Resumen

Central European tickborne encephalitis (TBE) is a viral disease of the central nervous system. Despite a surveillance system for TBE existing in Poland since 1970, there are no standardised case definitions and different diagnostic tests are used in various regions. The purpose of this study was to summarise four years of surveillance data using standardised case definitions. From 1999 to 2002, 607 cases of TBE were reported to Poland’s national surveillance system: 386 (63.6%) were males, 331 (54.5%) lived in rural areas, and 186 (30.6%) were between 30 and 50 years old. Of 606 diagnosed cases, 453 (74.7%) had aseptic meningitis, 109 (18.0%) had meningoencephalitis, and 44 (7.3%) had meningoencephalomyelitis. Of the 607 reported cases, 602 (99.2%) could be classified: 153 (25.4%) as confirmed, 343 (57.0%) as probable, and 106 (17.6%) as possible cases. There was a significant difference in classified cases by gender: 28.6% of male cases were classified as confirmed, compared with 19.7% of female cases (chi2= 10.48, p=0.0053). There was a significant difference in case classification by clinical diagnosis: 32.4% of cases with meningoencephalitis were classified as confirmed cases, compared with 24.7% of cases with aseptic meningitis (chi2=11.79, p=0.019). There were also significant differences in the distribution by case definition group across geographical regions. For appropriate monitoring of TBE, a uniform and valid case definition should be used in European countries. With only 25% of reported cases meeting the definition for confirmed cases, there is a need for more complete follow-up and standardised testing of suspect cases.

Resumen

The abuse and misuse of antibiotics is one of the main drivers of antimicrobial resistance (AMR). Globally, AMR in food-producing animals is a significant public health concern. This study, therefore, assessed the knowledge, attitudes, and practices related to antibiotic usage (AMU) and AMR among poultry farmers in Nepal. We conducted a cross-sectional survey of 605 poultry farmers from six districts of Nepal from May to June 2022 to assess the status of knowledge, attitude, as well as practices toward prudent antibiotic usage (AMU) and AMR. The majority of the participants in our study were from the Chitwan district (31.6%; n = 191/605), aged 30–44 (54.2%; n = 328/605), males (70.4%; n = 426/605), and farmers with a higher secondary (28.76%; n = 174/605) level of education. The tetracyclines (28%, n = 228/828), aminoglycosides (23%, n = 188/828), and fluoroquinolones (15%, n = 126/828) were the most used antibiotics classes among poultry farmers. Although 87.8% (n = 531/605) of poultry farmers used antibiotics, 49.8% (n = 301/605) of them were aware of AMR, and 55.7% (n = 337/605) knew that the misuse of antimicrobials could affect human and environmental health. There were significant differences in the knowledge, attitude, and practices toward prudent AMU and AMR among farmers who reared different birds. The mean knowledge, attitude, and practice score of the respondents were 7.81 ± 3.26, 5.8 ± 2.32, and 7.59 ± 3.38 when measured on a scale of 12, 10, and 15, respectively. Based on a cut-off of 75% of the maximum score, 49.4% (n = 299/605), 62.8% (n = 380/605), and 12.73% (n = 77/605) of the respondents had good knowledge, attitude, and practices toward prudent AMU and AMR, respectively. The multivariable logistic regression analyses revealed that the positive predictors of good knowledge and attitude were male gender, higher level of education, district, and the types of birds (layers). Similarly, those of the male gender (OR: 3.36; 95% CI: 1.38–8.20; p = 0.008) and those that rear layers (OR: 4.63; 95% CI: 1.75–12.25; p = 0.003) were more likely to practice prudent usage of antimicrobials. The findings of this study show poor practice toward prudent antibiotic usage despite good knowledge of AMR. This study provides essential baseline data on the knowledge, attitudes, and practices of poultry farmers in Nepal and offers valuable insights that could help in the design of interventions and policies aimed at addressing illicit AMU and AMR in poultry in Nepal.

Resumen

Abstract Background The proto-oncogene ERG is located on chromosome 21q22 and overexpression of ERG was shown to have an adverse impact on outcome in cytogenetically normal AML (CN-AML). Acquired gain of chromosome 21 (+21) is a recurrent cytogenetic abnormality in AML, however, the pathogenetic impact remains elusive. Data indicate that +21 could be the underlying mechanism for altered expression of genes located in the respective regions, such as ERG, which might contribute to the pathogenesis in myeloid malignancies with +21. Aims 1) To investigate a possible relationship between ERG copy numbers and variations in ERG mRNA expression levels in patients (pts) with myeloid malignancies. 2) Analysis of ERG expression in CN-AML to reveal a possible association between ERG overexpression and other relevant molecular markers and to ascertain the prognostic impact of ERGin context of these markers. Methods ERG mRNA expression and ERG copy numbers were analyzed using a hydrolysis probe based real-time PCR assay. 1) To address ERG expression in relation to +21 the following cohorts were analyzed: 62 AML pts with a complex karyotype including +21 (CK+21); 44 AML pts with a non-complex aberrant karyotype including +21 (AK+21); 19 pts with various myeloid malignancies (10 de novo AML, 3 MDS, 1 s-AML, 2 t-AML, 1 MDS/AML, 1 t-MDS, 1 MDS/MPN) all of them showing ERG amplification by interphase FISH and array CGH (ERG-Amp). In addition, 32 CK-AML and 330 CN-AML pts without +21 or ERGamplification were analyzed. Results were expressed as mean values±SEM. Expression levels/DNA copy numbers were compared by t-test. 2)ERG expression was assessed in a cohort of 330 patients (<65 years) with de novo CN-AML. Female/male ratio was 169/161. To distinguish low from high ERG expressers the median %ERG/ABL1 level was used. BAALC expression levels were analyzed accordingly. Expression levels were correlated with clinical outcome and with the presence of mutations (mut) in ASXL1 (n=330), CEBPA (n=330), DNMT3A (n=261), FLT3-TKD (n=330), IDH1R132 (n=328), IDH2R140 (n=328), IDH2R172 (n=328), NPM1 (n=330), NRAS (n=330), RUNX1 (n=329), TET2 (n=166), WT1 (n=329) and FLT3-ITD (n=330), and with MLL-PTD (n=330) and BAALCexpression (n=328). Results 1) Analysis of pts with +21 or ERG-Amp revealed significantly higher expression levels of ERG in pts with +21 (AK+21 and CK+21 combined, 331 ± 28) and ERG-Amp (606 ± 127) as compared to pts with CN-AML (229 ± 10; p=0.001, p=0.008, respectively) or CK-AML (177 ± 36; p=0.001, p=0.004, respectively). Mean ERG expression was even higher in pts with ERG-Amp (606 ± 127) as compared to pts with +21 (331 ± 28, p=0.047). Quantification of ERG copy numbers on DNA level showed good correlation to ERG mRNA expression, with abundantly higher ERG DNA amount in +21 (3.25 ±0.14) and moreover in ERG-Amp (9.21 ±1.05) as compared to CN-AML and CK-AML (combined: 2.20 ± 0.05; p<0.001 and p<0.001, respectively). 2) In CN-AML, %ERG/ABL1 levels ranged from 0.078 to 1,016.027 (median: 188.904). High ERG expression was associated with lower age (mean: 48.7 vs. 52.4 years, p=0.002), higher white blood cell (WBC) count (mean: 64.8 vs. 44.4 x 109/L, p=0.019), FLT3-ITDmut/wt ratio≥0.5 (51/165, 30.9% vs. 24/165, 14.5%, p=0.001), IDH2R172mut (6/164, 3.7% vs. 0/164, 0.0%, p=0.030) and high BAALC expression (104/164, 63.4% vs. 59/164, 36.0%, p<0.001), as compared to low ERG expression. In contrast, NPM1mut (91/165, 55.2% vs. 118/165, 71.5%, p=0.003), IDH1R132mut (10/165, 6.1% vs. 29/163, 17.8%, p=0.001) and TET2mut (10/76, 13.2% vs. 22/90, 24.4%, p=0.077) were less frequent in high ERG expressers. Survival analysis revealed inferior overall survival (OS at 3 years: 52.2% vs. 68.7%, p=0.021) and event free survival (EFS at 3 years: 34.6% vs. 43.1%, p=0.052) for high ERG expressers as compared to low ERG expressers. In a multivariate analysis adjusted for age, WBC, BAALC expression, FLT3-ITDmut/wt ratio≥0.5, MLL-PTD and WT1mut, high ERG expression revealed a trend towards an adverse impact on OS (p=0.069), while no impact on EFS was observed. Conclusions 1) Gain of chromosome 21 and especially amplification of chromosomal band 21q22 is a mechanism for ERG overexpression. This might indicate ERG as an important factor contributing to the pathogenesis and progression of myeloid malignancies with gain of chromosome 21. 2) In CN-AML, ERG overexpression is associated to several molecular markers and has a negative impact on OS and EFS.

Resumen

Transformation behaviors and texture of Ni47Ti44Nb9 cold-rolled plates were studied by differential scanning calorimetry and X-ray diffraction test. R phase transformation does not occur in Ni47Ti44Nb9cold-rolled plate annealed at 350°C-750°C followed by quenching into the water. Martensite transformation temperature first increases and then decreases with increment of annealing temperature, and the maximum achieves at 700°C. The heat of reverse martensite transformation increases, while hardness decreases as annealing temperature increases. The major texture of cold-rolled plate is {332} and spread from {332} to {110}. When the annealing temperature is above 600°C, the major textures are {332} and {111} recrystallization texture in secondary cold-rolled plate.

Resumen

Background/Objectives: Although the overall survival prognosis of patients in advanced stages of pancreatic ductal adenocarcinoma (PDAC) is poor, typically ranging from days to months from diagnosis, there are rare cases of patients remaining in therapy for longer periods of time. Early estimations of survival prognosis would allow rational decisions on complex therapy interventions, including radical surgery and robust systemic therapy regimens. Understandably, there is great interest in finding prognostic markers that can be used for patient stratification. We determined the role of various KRAS mutations in the prognosis of PDAC patients using biopsy samples and circulating tumor DNA. Methods: A total of 118 patients with PDAC, clinically confirmed by endoscopic ultrasound-guided fine-needle aspiration biopsy (EUS-FNB), were included in the study. DNA was extracted from cytological slides following a standard cytology evaluation to ensure adequacy (viability and quantity) and to mark the tumor cell fraction. Circulating tumor DNA (ctDNA) was extracted from plasma samples of 45 patients in stage IV of the disease. KRAS mutations in exons 12 and 13 were detected by denaturing capillary electrophoresis (DCE), revealing a minute presence of mutation-specific heteroduplexes. Kaplan–Meier survival curves were calculated for individual KRAS mutation types. Results:KRAS mutations were detected in 90% of tissue (106/118) and 44% of plasma (20/45) samples. All mutations were localized at exon 2, codon 12, with G12D (GGT > GAT) being the most frequent at 44% (47/106) and 65% (13/20), followed by other types including G12V (GGT > GTT) at 31% (33/106) and 10% (2/20), G12R (GGT > CGT) at 17% (18/106) and 10% (2/20), G12C (GGT/TGT) at 5% (5/106) and 0% (0/20) and G12S (GGT/AGT) at 1% (1/106) and 5% (1/20) in tissue and plasma samples, respectively. Two patients had two mutations simultaneously (G12V + G12S and G12D + G12S) in both types of samples (2%, 2/106 and 10%, 2/20 in tissue and plasma samples, respectively). The median survival of patients with the G12D mutation in tissues was less than half that of other patients (median survival 101 days, 95% CI: 80–600 vs. 228 days, 95% CI: 184–602), with a statistically significant overall difference in survival (p = 0.0080, log-rank test), and furthermore it was less than that of all combined patients with other mutation types (101 days, 95% CI: 80–600 vs. 210 days, 95% CI: 161–602, p = 0.0166). For plasma samples, the survival of patients with this mutation was six times shorter than that of patients without the G12D mutation (27 days, 95% CI: 8–334 vs. 161 days, 95% CI: 107–536, p = 0.0200). In contrast, patients with detected KRAS G12R in the tissue survived nearly twice as long as other patients in the aggregate (286 days, 95% CI: 70–602 vs. 162 days, 95% CI: 122–600, p = 0.0374) or patients with other KRAS mutations (286 days, 95% CI: 70–602 vs. 137 days, 95% CI: 107–600, p = 0.0257). Conclusions: Differentiation of specific KRAS mutations in EUS-FNB and ctDNA (above all, the crucial G12D and G12R) is feasible in routine management of PDAC patients and imperative for assessment of prognosis.

Resumen

The article presents data of studies carried out in the northwestern part of the Non-Chernozem zone (Tver region) in 2019. Studied were fodder mixtures based on meadow clover Kretunovsky, Green, Chance, Falensky 86 varieties mixed with variegated alfalfa Vega 87 variety and cereal components − timothy grass VIK 9 and meadow fescue Sakharovskaya varieties. The yield of dry weight of legumes and cereal grass stands of the first year of use during primary mowing in ferti-lized varieties was 4.4-6.9 t/ha at the height of grass stand of 66-77 cm and stalk density of 318-507 pcs/m2. The indicators in variants without fertilizers were lower, the height of the grass stand was 63-69 cm, the density was 334-595 pcs/m2 and the yield of fodder mass was 3.8-4.6 t/ha. Unfavorable climatic conditions during the period between mowings had a suppressive effect on growth and development of herbs, therefore, during the secondary mowing the height parameters of agrophytocenoses decreased by 1.2-1.3 times and did not exceed 32-44 cm against unfertilized background, 43-53 cm against a fertilized one. A decrease in shoot formation ability of herbs during the second mowing was not observed, the density of agrophytocenoses was at the level of 300-500 pcs/m. The yield of dry mass of the second mowing compared to the first mowing decreased by 1.3-1.7 times and was 2.2-5.4 t/ha. In the botanical composition of grass mixtures during the first mowing, leg-ume components prevailed − 35-65 %, during the secondary mowing the percentage of legumes did not exceed 15-30 %. The use of three-component grass mixtures in agriculture will make it possible to get from 6.7 to 9.3 tons per hectare of dry weight of complete feed for cattle for two mowings. Adaptation and cultivation on sod-podzolic soils in the humid zone of the Non-chernozem region of grass mixtures consisting of new-generation forage grasses is one of the reserves for increasing produc-tivity of forage crops by more than 10 %.

Resumen

602 Background: The Kyushu Study group of Clinical Cancer conducted a phase II study that evaluated the FIREFOX regimen. (KSCC0701, Akagi et al, J Clin Oncol 28:15s, 2010). This study demonstrated the efficacy and mild neurotoxicity of this regimen. The present study evaluated the efficacy and safety of the FIREFOX plus bevacizumab (bev). Methods: Eligibility criteria included histologically confirmed advanced colorectal cancer, ECOG PS 0-2 and adequate bone marrow, renal and hepatic function. Patients (pts) received an alternating regimen of 4 cycles of mFOLFOX-6 plus bev (oxaliplatin 85 mg/m2, leucovorin 200 mg/m2, bev 5 mg/kg d1 followed by 400 mg/m2 bolus 5-FU and a 46-hr 2,400 mg/m2 5-FU infusion every 2 weeks) followed by 4 cycles of FOLFIRI plus bev (oxaliplatin replaced with irinotecan 150 mg/m2 d1). This schedule was repeated until unacceptable toxicity or disease progression occurred. The primary endpoint is progression-free survival. (UMIN000001312) Results: Of the 52 pts enrolled from May 2008 to July 2009. Two of the patients did not fulfill the eligibility criteria. M/F, 30/20; median age, 59.5 years (range 37 - 75); ECOG PS 0/1/2, 46/4/0. The median number of administration cycles was 14 (range, 2 - 44). Response rate (RECIST criteria) for CR, PR, SD, PD and NE were 2 (4%), 28 (56%), 14 (28%), 4 (8%) and 2 (4%), respectively. An overall response rate was 60% (95% CI: 45 - 74%). Median progression-free survival was14.2 M (95% CI: 10.6 M-16.3 M) and median overall survival was 27.5 M (95% CI; 22.4 M – not determined). The 2-year survival rate was 56.8%. Of the 52 pts evaluated for toxicity. The most common grade 3-4 adverse events were leukopenia (7.7%), neutropenia (32.7%), anemia (1.9%), fatigue (9.6%), anorexia (13.5%), stomatitis (3.8%), neurotoxicity (3.8%), hypertension (1.9%), diarrhea (7.7%), febrile neutropenia (3.8%), nausea (9.6%), vomiting (5.8%), hypersensitivity (3.8%), and thromboembolism (1.9%). Conclusions: The results of this phase II study show that the FIREFOX plus bev regimen is effective and well tolerated in the first-line treatment of advanced colorectal cancer. The low rate of neurotoxicity is also promising.

Resumen

Contrary to experimental animals, it is well known that pig oocytes show low developmental competence after IVM, fertilization and culture despite of the attempts to improve the IVM technology. One of the reasons causing such low developmental ability of porcine oocytes seems to be the culture condition, especially the gas phase for IVM because there is a large differences in oxygen tension between in vitro and in vivo conditions. Indeed, our preliminary study revealed that oocytes matured in vivo had larger perivitelline space than oocytes matured in vitro, which could be affected by in vitro culture condition. The present study was conducted to evaluate the effect of oxygen tensions on nuclear maturation, cumulus expansion and glutathione synthesis of porcine oocytes during IVM. COCs at the germinal vesicle stage were collected from ovaries of prepubertal gilts and cultured in modified NCSU37 either under 2, 5, or 20% O2 for 44 h (Group 2%, Group 5%, and Group 20%, respectively). Five percent CO2 was used for all groups. After culture, the cumulus expansion was morphologically evaluated by classification to three grades (Grade 1: excellent [the length of expanded cumulus cells was longer than the diameter of the oocyte], Grade 2: good [the length of expanded cumulus cells was less than the diameter of oocyte], Grade 3: poor [oocyte having partial or single layer of expanded cumulus cells]). All experiments in this study were replicated more than 5 times. Data were analyzed by ANOVA and then shown as mean ± SD%. The rate of Grade 1 in Group 2% (16.8 ± 8.3%, 32/189) was significantly lower than those in Group 5% (68.2 ± 11.2%, 149/228) and Group 20% (78.6 ± 6.9%, 162/201) (P < 0.05). As for rates of Grade 2 and Grade 3, there were no significant differences between the groups. After evaluation of cumulus expansion, cumulus cells were removed and oocytes were stained by aceto-orcein for evaluation of nuclear maturation. The rates of metaphase II-stage oocytes were 41.0 ± 12.4% (86/210), 47.6 ± 20.5% (119/263) and 47.7 ± 12.9% (100/199) in Group 2%, Group 5%, and Group 20%, respectively. There were no significant differences among the groups. In order to clarify the effect of oxygen concentration on cytoplasmic maturation, COCs were cultured for 44 h and glutathione level of the oocytes was measured by 5,5′-dithio-bis-2-nitro-benzonic acid-glutathione disulfide reductase recycling method. Regardless the oxygen concentration, glutathione level was increased from the start of culture (6.2 ± 3.9 pmol/oocyte). But there were no significant differences in the glutathione level among groups. These results suggest that oxygen concentration during IVM could affect cumulus expansion but not nuclear maturation and cytoplasmic glutathione level in pig oocytes.

Resumen

Purpose: The authors investigated the effects of sex, energy availability (EA), and health status on the change in hemoglobin mass (ΔHbmass) in elite endurance athletes over ∼3–4 wk of live-high–train-high altitude training in Flagstaff, AZ (2135 m; n = 27 women; n = 21 men; 27% 2016 Olympians). Methods: Precamp and postcamp Hbmass (optimized carbon monoxide rebreathing method) and iron status were measured, EA was estimated via food and training logs, and a Low Energy Availability in Females Questionnaire (LEAFQ) and a general injury/illness questionnaire were completed. Hypoxic exposure (h) was calculated with low (<500 h), moderate (500–600 h), and high (>600 h) groupings. Results: Absolute and relative percentage ΔHbmass was significantly greater in women (6.2% [4.0%], P < .001) than men (3.2% [3.3%], P = .008). %ΔHbmass showed a dose–response with hypoxic exposure (3.1% [3.8%] vs 4.9% [3.8%] vs 6.8% [3.7%], P = .013). Hbmasspre was significantly higher in eumenorrheic vs amenorrheic women (12.2 [1.0] vs 11.3 [0.5] g/kg, P = .004). Although statistically underpowered, %ΔHbmass was significantly less in sick (n = 4, −0.5% [0.4%]) vs healthy (n = 44, 5.4% [3.8%], P < .001) athletes. There were no significant correlations between self-reported iron intake, sex hormones, or EA on Hbmass outcomes. However, there was a trend for a negative correlation between LEAFQ score and %ΔHbmass (r = −.353, P = .07). Conclusions: The findings confirm the importance of baseline Hbmass and exposure to hypoxia on increases in Hbmass during altitude training, while emphasizing the importance of athlete health and indices of EA on an optimal baseline Hbmass and hematological response to hypoxia.

Abstract Introduction The aim of this study was to assess the prevalence of respiratory symptoms, diseases and ventilatory defects. Methods This cross-sectional study involved 365 marble workers in Casablanca, and Agadir, with at least two years’ seniority. It included a questionnaire, spirometry and thoracic radiophotography. The questionnaire consisted of four sections: socio-demographic and occupational characteristics, smoking habits, medical history and clinical respiratory symptoms. Chronic bronchitis is defined as chronic cough and chronic sputum production occurring for at least three months per year and for at least two consecutive years without any other identified cause. The diagnosis of COPD was made in the presence of an obstructive ventilatory defect based on a ratio of forced expiratory volume at the first second/ forced vital capacity (FEV1/ FVC) <70% after administration of a bronchodilator. Results Average age was 38,5±10.4 years. The average seniority was 13,1 ±6.4 years. 23,3% were current smokers, 12.3% former smokers and 64.3% non-smokers. The prevalence of tracheobronchial irritation symptoms was 23.5: 15 % for chronic cough, 7.8 % for respiratory discomfort, 4.9 % for chronic sputum and 7.9% for chest wheezing. The prevalence of rhinitis was 20%, asthma 7.5%, chronic bronchitis 17% and chronic obstructive pulmonary disease 6.2% (6.9% in current and former smokers versus 2.9% in non-smokers). 21.3% had deficits in the (FEV1) and the (FVC). This prevalence reached 44% in current and former smokers. The prevalence of radiological abnormalities was 14.9% (3.8% were emphysema, 3.3% were small parenchymal opacities suggestive of pneumoconiosis). Conclusion These craftsmen must benefit from occupational medical coverage for better prevention.

Resumen

Numerous factors affect on the developmental competence of cloned embryos, and one of the factors might be the disturbed synchronization of nuclear and cytoplasm maturation. Roscovitine, a purine known to specifically inhibit M-phase promoting factor (MPF) kinase activity by blocking the ATP in numerous cell systems, has been successfully used in maintaining porcine oocytes at GV stage without affecting their developmental potential. However, developmental ability of roscovitine treated porcine oocytes after nuclear transfer has not been evaluated. The purpose of this study was to examine the development of nuclear transferred porcine embryos after meiotic inhibition with roscovitine (ROS). Cumulus-oocyte complexes (COCs) were collected from antral follicles of slaughtered prepubertal gilts. COCs were cultured in pre-maturation medium (TCM-199 containing 50 �M Roscovitine) for 24 h, and then further cultured in conventional maturation medium for 44 h. A control group was cultured in the maturation medium for 44 h. Matured oocytes were enucleated and a porcine fetus cell was inserted into each enucleated oocyte. Couplets were simultaneously fused and activated with electric pulse of two 1.2 kV/cm for 30 �s. Nuclear transferred (NT) embryos were cultured in PZM-1 medium for 6 days (five replicates). Apoptotic cell death was analyzed by using a TUNEL assay and total cell number was examined by Hoechest 33342 counterstaining. At 3 h after fusion, NT embryos were fixed for microfilament staining. Data were analyzed by ANOVA and Student's t-test. The rates of fusion, cleavage, and blastocyst formation of the ROS-treated group (85, 68, and 18%, respectively) after nuclear transfer did not differ from control (78, 76, and 16%, respectively). The cell number in blastocysts of the ROS-treated group (30.8 � 10.6) was significantly lower than that of the control (42.3 � 13.7) (P < 0.01), but the mean proportion of apoptotic cells was not different between the two groups (6.9 � 7.1 and 4.8 � 4.9% for control and ROS group, respectively). Recovery of microfilaments after fusion was delayed in NT embryos derived from ROS-treated oocytes. This study demonstrated that porcine oocytes pre-cultured for 24 h in presence of roscovitine can be developed to blastocysts after somatic cell nuclear transfer. This could provide flexibility for studying porcine oocyte development and embryo cloning.

Resumen

The Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) survey has received increased attention to determine which demographics may influence patient satisfaction after Total Hip and Knee Arthroplasty. The purpose of this study was to evaluate the various effects that patient-specific factors, medical comorbidities, and demographics had on patient satisfaction. Two thousand and ninety-two patients underwent lower extremity total joint arthroplasty at our institution between 2014 and 2018. Nine hundred twenty-three of these patients responded to their HCAHPS survey (44%). Most patients (609, 66%) underwent primary total knee arthroplasty followed by 244 (26.4%) total hip arthroplasties, 35 (3.8%) revision total knee arthroplasties, 28 (3.0%) bilateral total knee arthroplasties, and 7 (0.8%) revision total hip arthroplasties. Increasing age and length of stay were associated with a decrease in patient satisfaction whereas patients who were married reported higher satisfaction. Patients discharged to a rehabilitation facility had a 12% decrease in top-box response rate compared to those discharged home. Contrary to our hypothesis, specific procedure type and the presence of comorbidities failed to predict patient satisfaction. The results of this study shed light on the intricate relationship between patient satisfaction and patient-specific factors. Furthermore, health care workers can counsel patients on expected satisfaction when considering total hip and knee arthroplasty.

Resumen

Context.— Adenocarcinoma in situ (AIS) is difficult to correctly interpret on Papanicolaou (Pap) cytology slides and false-negative interpretations of AIS can cause significant problems in daily practice. Objective.— To investigate the false-negative interpretation rate of AIS and the factors related to false-negative interpretation through responses in an educational environment. Design.— We retrospectively evaluated 11 337 responses in the PAP Education Program (PAP-Edu) from 173 AIS slides from 2011 to 2015. The false-negative interpretation rate, most common false-negative interpretations, and related other factors were evaluated. Results.— The overall false-negative rate was 6.9% (784 of 11 337). Respondents correctly interpreted AIS 50.0% (5667 of 11 337) of the time; high-grade intraepithelial lesion (HSIL) and malignancies (adenocarcinoma, squamous cell carcinoma, and other carcinomas) accounted for 42.7% (4842 of 11 337) and low-grade intraepithelial lesion accounted for 0.4% (44 of 11 337) of responses. Overall, 92.7% (10 509 of 11 337) of responses were HSIL and above. Among 784 false-negative responses, negative for intraepithelial lesion or malignancy was the most common (61.5% [482 of 784]), followed by reparative changes (24.1% [189 of 784]) and atrophic vaginitis (7.7% [60 of 784]). Overall, pathologists' responses showed a significantly higher false-negative rate than cytotechnologists' responses (8.3%, 403 of 4835 versus 5.7%, 275 of 4816; P < .001). The false-negative response rates were not statistically different among preparation types. Conclusions.— The low correct interpretation rate and higher false-negative rate for AIS demonstrate the difficulty in interpreting AIS on Pap cytology, which may cause clinical consequences. The higher false-negative rate with pathologists than with cytotechnologists suggests cytotechnologists' higher screening sensitivity for AIS or cautious interpretation to avoid false-positive results by pathologists.

Resumen

Abstract. Due to negative effects of high ambient temperature, the present study was conducted to investigate the effects of Portulaca oleracea hydroextract (PHE) and zinc (Zn) on the growth performance and immunity of broiler chickens reared under high summer ambient temperature conditions. A total of 420 day-old male broiler chickens (Ross 308) were randomly allocated to seven dietary treatments each replicated four times with 15 birds per replicate. The basal diet as the control diet was supplemented with 100 mg kg−1 butylated hydroxytoluene (BHT), or 300 and 600 mg kg−1 of PHE, 100 mg kg−1 of zinc and 100 mg kg−1 of zinc plus 300 or 600 mg kg−1 of PHE (ZP300 and ZP600). The result of the present study showed that Zn, PHE and their combination did not alter daily feed intake and feed conversion ratio. Although there was a tendency toward an increase in broiler body weight at 24 and 44 days of age (P=0.059 and P=0.061), the body weight of birds fed the basal diet supplemented with Zn reduced at day 10. The birds fed diets supplemented with BHT or ZP600 showed lower aspartate aminotransferase (ASAT) and lactate dehydrogenase activity at 24 days of age (P<0.05), but it remains lower in the ZP600 group only for ASAT activity level at day 44. The results of the present study suggest that dietary PHE and Zn supplementation partially improved body weight and serum antioxidant capacity, superoxide dismutase activity and antibody titer against sheep red blood cells and Newcastle diseases in the broiler chickens during summer conditions.

Resumen

602 Background: We previously reported that an adaptive Th1 immune response (CD3/CD8/CD45RO T-cells) observed in resected primary colorectal tumor and liver colorectal metastases (LCM) is an important prognostic factor. B and FoxP3 regulatory lymphocytes participate to the modulation of this response. We aimed to investigate whether the preoperative treatments influenced the quality and the density of the immune infiltrates previously reported in the LCM. Methods: We used a cohort of metastatic colorectal patients (n=107) engaged for curative liver surgery with available FFPE blocks for all resected LCM to confirm the prognostic impact of the immune response. Among this cohort of 338 LCMs, 46 were completely resected after chemotherapy (CT) alone, 130 after CT + anti-VEGF, 118 after CT + anti-EGFR and 44 after surgery alone. LCMs were analyzed for histological response according the Tumor Regression Grade (TRG) and regrouped as Response (R, TRG1-3) or No Response (NR, TRG4-5). The density of CD3+ (T-cells), CD8+ (cytotoxic), CD45RO+ (memory), CD20+ (B-cells) and FoxP3+ (regulatory) in the core (CT) and invasive margin (IM) of all LCM was quantified on immunostained slides. The mean density value (CT/IM) was calculated for each marker with a dedicated image analysis software on whole-slide imaging. Comparisons were made using the Wilcoxon-Mann-Whitney test. Results: LCMs showing R (compared to NR and untreated LCM) were more frequently associated with a high immune infiltrate for CD3+ (CT: p<0.005; IM: p<0.05), CD8+ (CT: p<0.005; IM: p<0.005) and CD20+ (CT: p<0.05). Conversely, high FoxP3+ density in the CT and IM was related to NR and untreated LCMs (p<0.01). LCMs treated with an anti-EGFR therapy showed higher densities of CD3+ (CT: p<0.005; IM: p<0.01), CD8+ (CT: p<0.005), CD45RO+ (CT: p<0.005), CD20+ (CT: p<0.005) and FoxP3+ (CT: p<0.05; IM: p<0.005) compared to other treatments and untreated LCMs. Conclusions: Preoperative treatment modifies the LCM immune microenvironnement. LCMs with a histological response show a cytotoxic immune response (CD3+/CD8+) with associated B-cells (CD20+) and downregulated Tregs (FoxP3+). The use of an anti-EGFR therapy significantly increases immune infiltration in the CT.

Resumen

Introduction: The habits children have included in life; continues to make the choices they make as adults. According to social learning theory these habits are derived through supervision, learning and modelling. For a child, most significant are primarily father and mother and their immediate family members. All these factors have the collective ability to influence the child's oral health outcomes. Objective: To examine the dental caries rate in 5 year’s old school children and influence of their family related habits and socio demographic factors on child’s dental caries experience and their oral health behavior. Methodology: This study conducted upon sample of 600 school children selected through random sampling from primary private and Government primary schools of Qasimabad Hyderabad Sindh during period of October 2015 to December 2015. Results: shows that out of 600 children 330 (55%) were boys and 270 (45%) were girls. Boys 245 (40%) were affected from caries and 85 (14%) were free from caries. In relation to parental education; 44 (7.3%) child boys whom parents were highly educated were found affected by caries 44(7.3%), while 3 (0.5%) boys were free from caries. Girls whose parents were highly educated affected by caries were 44(7.3%), caries free were 12(2%) Boys whose parents have incomplete secondary education/ vocational school were affected by caries 162(27%) and caries free were 82(13.6%). Girls whose parents have incomplete secondary / vocational school were affected by caries 145 (24.1%). Boys whose parents were having low level of education affected by caries were 39(6.5%) while caries free were 0 (0%). Girls whose parents have low level of education were affected by caries were 69 (11.5%) while caries free were 0 (0%) . Conclusion: Life style choices are the habits that are formed in childhood and dictated as in adult hood. Thus, assessing family related risk factor regarding oral health is essential when conducting preventive treatment programs for children because education on oral hygiene maintenance and regular preventive dental health checkups are very important in order to prevent oral diseases. Key words: Dental Caries, primary dentition.

Resumen

Abstract Multiple oncolytic viruses have been shown to induce multifaceted changes in the tumor microenvironment, that ultimately support induction of anti-tumor immune responses. We have previously demonstrated that CodaLytic, a codon-modified influenza virus, can kickstart the cancer immunity cycle at various steps in several mouse models with differing baseline immune contextures. Here, we are describing the activity of a new codon-modified virotherapeutic derived from the same synthetic viral engineering platform [Coleman et al., Science 2008]. Zika virus strain MR766 was synthetically codon-modified at 664 positions in the envelop gene to yield CDX-602. Virus was originally passaged in Vero cells and working stocks were expanded in BSR-T7 cells for in vivo use after titration on MA104.1 cells. Efficacy after intratumoral injection of 107 PFU/dose CDX-602 alone or in combination with 200 μg/dose αPD-1 blockade (RMP1-14, i.p.) was determined in subcutaneous B16-F10 melanoma and orthotopic EMT6 breast cancer models (n = 10). Changes in the tumor immune infiltrate were characterized using flow cytometry 6 or 8 days after treatment initiation, respectively (n = 5). In the immunotherapy-resistant B16-F10 model, CDX-602 monotherapy led to highly reproducible tumor growth inhibition (TGI, 52%, p < 0.0001 vs vehicle control), resulting in modest, but significant prolongation of median survival (25%, p < 0.01). Anti-tumor efficacy correlated with increased tumor immune infiltration with CD4+ and CD8+ T cells (R2 = 0.68 and 0.67, respectively, p < 0.01). Importantly, frequencies of cross-presenting dendritic cells (cDC) were increased 3.8-fold (p < 0.0001) after virus treatment, while no compensatory influx of CD206+ macrophages was observed, suggesting immune contexture changes conducive to anti-tumor immune induction. Efficacy was confirmed in the EMT6 model, in which monotherapy TGI was 44% and thus on par with αPD-1 blockade (50%, both p < 0.0001 vs control). Combination viroimmunotherapy in this model further improved efficacy, leading to 71% TGI and a doubling in complete regressions to 40%. Inclusion of CDX-602 in the treatment regimen led to similar changes in immune infiltration, in particular recruitment of CD8+ T cells and cDCs (9.7-fold and 6.9-fold increase after combination, respectively). Additional ex vivo analyses to confirm induction of anti-tumor immune responses are ongoing. Taken together, this preclinical data establishes CDX-602 as a novel virotherapeutic candidate that engages multiple mechanisms of action that contribute to anti-tumor activity. CDX-602 is the second virotherapeutic candidate derived from Codagenix’s codon modification platform, further supporting the utility of this synthetic viral engineering technology for viroimmunotherapy of cancer and highlighting its potential across multiple viral species.

Resumen

Augmenting bacterial growth is of great interest to the biotechnological industry. Hence, the effect of poly (caprolactone) fibrous scaffolds to promote the growth of different bacterial strains of biological and industrial interest was evaluated. Furthermore, different types of carbon (glucose, fructose, lactose and galactose) and nitrogen sources (yeast extract, glycine, peptone and urea) were added to the scaffold to determinate their influence in bacterial growth. Bacterial growth was observed by scanning electron microscopy; thermal characteristics were also evaluated; bacterial cell growth was measured by ultraviolet-visible spectrophotometry at 600-nm. Fibers produced have an average diameter between 313 to 766 nm, with 44% superficial porosity of the scaffolds, a glass transition around ~64 °C and a critical temperature of ~338 °C. The fibrous scaffold increased the cell growth of Escherichia coli by 23% at 72 h, while Pseudomonas aeruginosa and Staphylococcus aureus increased by 36% and 95% respectively at 48 h, when compared to the normal growth of their respective bacterial cultures. However, no significant difference in bacterial growth between the scaffolds and the casted films could be observed. Cell growth depended on a combination of several factors: type of bacteria, carbon or nitrogen sources, casted films or 3D scaffolds. Microscopy showed traces of a biofilm formation around 3 h in culture of P. aeruginosa. Water bioremediation studies showed that P. aeruginosa on poly (caprolactone)/Glucose fibers was effective in removing 87% of chromium in 8 h.

Abstract Abstract 5259 In this study, we attempted to determine the performance of the soluble fibrin monomer complex (SFMC) test in comparison to known activation markers, such as prothrombin fragment 1.2 (PF1.2), thrombin antithrombin complex (TAT) and d-dimer (DD). We have used the STA(R)-Liatest FM and STA(R)-Liatest D-Di kits to measure the SFMC and d-dimer levels. A total of 25 patients were included in this study. The data and demographic information are shown in the table below.

Only 3 out of 25 patients have elevated TAT and PF1.2 with normal SFMC levels. Therefore, our data would tend to indicate that SFMC level could be used as an activation marker to assess an ongoing prothrombotic process. In order to more fully determine the efficacy of the SFMC assay, we will obtain a detailed clinical history for the cases shown above. Disclosures: No relevant conflicts of interest to declare.

Resumen

Purpose:The study aimed to establish the test–retest reliability and convergent validity of PlayerLoad™ (triaxial-accelerometer data) during a standardized bout of treadmill running.Methods:Forty-four team-sport players performed 2 standardized incremental treadmill running tests (7–16 km/h) 7 d apart. Players’ oxygen uptake (VO2; n = 20), heart rate (n = 44), and triaxialaccelerometer data (PlayerLoad; n = 44) measured at both the scapulae and at the center of mass (COM), were recorded. Accelerometer data from the individual component planes of PlayerLoad (anteroposterior [PLAP], mediolateral [PLML], and vertical [PLV]) were also examined.Results:Moderate to high test–retest reliability was observed for PlayerLoad and its individual planes (ICC .80–.97, CV 4.2–14.8%) at both unit locations. PlayerLoad was significantly higher at COM vs scapulae (223.4 ± 42.6 vs 185.5 ± 26.3 arbitrary units; P = .001). The percentage contributions of individual planes to PlayerLoad were higher for PLML at the COM (scapulae 20.4% ± 3.8%, COM 26.5% ± 4.9%; P = .001) but lower for PLV (scapulae 55.7% ± 5.3%, COM 49.5% ± 6.9%; P = .001). Between-subjects correlations between PlayerLoad and VO2, and between PlayerLoad and heart rate were trivial to moderate (r = –.43 to .33), whereas within-subject correlations were nearly perfect (r = .92–.98).Conclusions:PlayerLoad had a moderate to high degree of test–retest reliability and demonstrated convergent validity with measures of exercise intensity on an individual basis. However, caution should be applied in making between-athletes contrasts in loading and when using recordings from the scapulae to identify lower-limb movement patterns.

Resumen

This work provides the reinterpretation results of the research outcomes with the DSS method on geotraverse IV on section PK 295-400 in order to clarify a seismic section in the Holovanivsk area of high gravity. A number of points of diffraction and seismic sites have been identified in Earth’s crust (at a depth of 2-60 km), which gives an opportunity to considerably specify the data on the deep structure of the studied area. The position in a section of the Talnivska fault zone is clarified due to the identification of additional points of diffraction and a large number of short reflective elements at a depth of 2-8 km. In the central part of the section (PK 338-355), horizontal and inclined elements (at the depths of 2-9 km and 24-44 km) and a series of short steeply inclined reflective elements (at depths of 8-26 km) form the area of the medium which at the depth of 2-44 km differs in its characteristics from the host rocks. This allowed tracing the listriс shear zone that stretches continuously from a depth of 8 km on PK 355 to 44 km on PK 304. All this, as well as available seismotomographic data, allows us to suppose that the Talnivska fault zone is traced up to depths of 100-600 km as a boundary between blocks with different Vp velocities and degrees and gaps in the Golitsyn—Geiko layer. The listriс shear zone is connected to the main part of the Talnivska fault zone near the surface. According to the given re-interpretation of GSS data on geotraverse IV, the supply channel of the intrusive body of hyperbasites is rather narrow at depths of 60-33 km, and starting only from depth of 30 km and almost to the surface the body expands up to 15 km in width. Focusing on the area of increased Vp velocities at a depth of 2-33 km, one can assume that the main intrusive body that consists of hyperbasites and basite-Dunites, peridotites, pyroxenites, gabbro, and amphibolites, the density of which exceeds the density of rocks by 0.1-0.22 g/cm3, is located at these depths along the axis of the central part of the Holovanivsk suture zone.

Resumen

ABSTRACT What are the long-term effects of hysterectomy on the ovaries of normal women? Ninety-three women aged 29–44 years (median, 38 years) who had undergone hysterectomy for benign reasons 0·3–9·1 years prior to investigation, contributed urine samples twice weekly for a period of 53–149 days (median 102 days) for pregnanediol analysis. The interval between successive pregnanediol peaks and their increment over baseline were measured. The median peak interval was 27·3 days, and 93·3% of all intervals were of 21- to 35-days duration. Of the 337 peaks observed, 96·7% met the criteria previously used to define an ovulatory cycle. These are similar to the figures reported for menstruant women of comparable age. ANOVA showed no significant effect of age or time since hysterectomy on either the interval between peaks or peak increment (P > 0·10 in all cases). The evidence suggests that the ovaries of women who have no uterus behave like those of intact women. Journal of Endocrinology (1992) 135, 597–602

Resumen

The Al–Mn alloy heat exchanger fin production process includes a brazing treatment at s high temperature of 600 °C, in which coarse grains are preferred for their high resistance to deformation at elevated temperatures by decreasing the grain boundary sliding. In this study, Al-1.57Mn-1.57Zn-0.58Si-0.17Fe alloy foils cold rolled by 81.7% (1.1 mm in thickness) and 96.5% (0.21 mm in thickness) were annealed at 100–550 °C for 1 h to investigate their recrystallization behavior, grain sizes, and precipitates by increasing the annealing temperature, using micro-hardness measurement, electron back-scattered diffraction (EBSD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM) techniques. The micro-hardness results showed that the recrystallization finishing temperatures for the two samples were almost the same, 323 ± 2 °C. The EBSD results showed that when the annealing temperature decreased from 550 to 400 °C, the recrystallized grain sizes of the two samples were nearly identical—both increased slightly. Further decreasing the annealing temperature from 400 to 330 °C caused the grain sizes to increase more, with the thinner foil sample having a more significant increase. The SEM and TEM observations showed that the micron-sized primary-phase remained unchanged during the annealing process. The nano-sized secondary phase precipitates formed during the hot-rolling process experienced a coarsening and dissolving process upon annealing. The particle size of the secondary phase increased from 32 nm to 44 nm and the area fraction decreased from 4.2% to 3.8%. The nucleation analysis confirmed that the large primary-phase could act as a nucleation site through particle stimulated nucleation (PSN) mode. The relatively dense secondary phase precipitates with small sizes at lower temperatures could provide higher Zener drag to the grain boundaries, leading to fewer nuclei and thereafter coarser grains. The coarsening of the recrystallized grains in the foils could be implemented through thickness reduction and/or precipitation processes to form densely distributed nano-sized precipitates.

Resumen

Abstract BACKGROUND Endoscopic assessment of disease severity is a key component of ulcerative colitis (UC) clinical studies. However, interobserver variability may contribute to bias in selecting study candidates and evaluating response rates. Scoring by blinded central readers has become the recommended standard method of assessment to minimize bias and interobserver variance. We present concordance rates between central and local readings from a Phase 2b study of investigational microbiome therapeutic SER-287 in patients with mild-to-moderate UC. METHODS This double-blind, placebo-controlled study screened 494 and randomized 203 adults (51.7% male; mean age 45.6 years; 83.7% white) 1:1:1 to 3 arms (Figure 1). Active UC was defined as ≥15 cm disease from the anal verge, a Three-Component Modified Mayo Score of 3-7, endoscopic subscore (ES) ≥1, and stool frequency subscore ≥1. Endoscopy was performed at screening, after induction, after exploratory maintenance or open-label, and for flare assessments. Endoscopic videos were scored by each site’s gastroenterologist (local ES), and by any 1 of 4 blinded central readers (Alimentiv; Ontario), with adjudication by a 2nd blinded central reader (Alimentiv), if necessary. If all 3 scores were discordant, the median score was designated as the final ES. Concordance between local and central readers were analyzed by timepoint and in total and quantified using weighted kappa statistics. RESULTS Concordance analyses were conducted for 608 ES comparisons between local and the 1st central reader (Local vs Central1 [LvC1]), and 337 comparisons where adjudication was necessary (Local vs Central2 [LvC2]; Central1 vs Central2 [C1vC2]). Observed concordance rates were: -LvC1: 44% (271/608, kappa = 0.61, Figure 2); -LvC2: 26% (86/337, kappa = 0.46); -C1vC2: 64% (216/337, kappa = 0.74). Concordance rates were comparable across study periods: -Screening: -LvC1: 42% (131/310, kappa = 0.59) -LvC2: 27% (48/179, kappa = 0.48) -C1vC2: 66% (118/179, kappa = 0.76) -Week 11: -LvC1: 46% (79/170, kappa = 0.61) -LvC2: 25% (22/91, kappa = 0.46) -C1vC2: 62% (56/91, kappa = 0.75) Local readers scored lower than C1 readers in 274/337 (81%) discordant cases (Figure 2), and lower than C2 in 221/251 (88%) discordant cases. The most frequent sources of discordance were L=ES2 vs C1=ES3 (153 videos) and L=ES1 vs C1=ES2 (77 videos). CONCLUSIONS In this Phase 2b study, low ES concordance highlights marked interobserver variability between local and blinded central readers. Local scores were consistently lower than central scores across all study time points. Despite low concordance rates, efficacy conclusions remain unchanged if only local ES scores were used for endpoint assessments. Objective, standardized, and consistent methods for evaluating ES are needed to better quantify disease severity and the impact of UC therapies.

Resumen

Abstract Introduction The hypomethylating agent 5-azacytidine (AZA) has been the standard of care for higher risk Myelodysplastic Syndromes (MDS) for the last few years. Its efficacy has been proven in large clinical trials, and its safety has been shown to be superior to that of conventional treatments. We have conducted a retrospective study about the efficacy and safety of 5-azacytidine, as reported and analyzed in our center. Patients and Methods Forty four consecutive patients with MDS or Acute Myeloid Leukemia (AML) with 20-30% bone marrow blasts that were treated with AZA during the last 63 months were included in the study. The clinical and laboratory characteristics of the patients were recorded, and the efficacy and safety data were analyzed. Results The epidemiologic and hematologic characteristics of the patients are shown in Table 1. The median overall survival was 13 months (1-101) and there was no primary treatment failure (Table 2). Serious adverse events consisted mostly of neutropenic infections (blood stream and pneumonia) (Table 3). Discussion Treatment with AZA offered a favorable (complete and partial) response in 34.1% of the patients, and an overall survival of 13 months, with generally predictable toxicities, although hospitalization was frequently inevitable during the first treatment cycles, when supportive treatment was a significant part of the management. A valuable observation is that there was a considerable decrease in the patients’ transfusion needs following treatment (p<0.0001). Our results are consistent with the results of other clinical trials and point out the need for investigational 5-azacytidine combinations. Table 1. Epidemiologic and hematologic characteristics.

Resumen

The purpose of this study was to evaluate the ophthalmic causes of headache among patients attending tertiary care hospital. This was a descriptive, cross sectional hospital-based study. One hundred and thirty-two patients with ocular cause of headache excluding primary headache and pediatrics patients during one year were included. Detail ocular examination was done including visual acuity, refraction, binocular vision assessment like convergence insufficiency and fusional insufficiency, anterior and posterior segment examination. Among headache patients, female was 106 (80.3%) and male was 26 (19.7%). The prevalence of headache in female was 6.9% and in male was 2%. Headache was more common in age group 18-29 (59.8%). The mean age of presentation was 29.9 ± 10.2 years (range 18-61 years). Out of 132 patients with headache, 104 (78.8%) had refractive error, 15 (11.4%) had fusional insufficiency, 6 (4.5%) had convergence insufficiency, 10 (7.6%) had anterior segment diseases and 5 (3.8%) had posterior segment diseases. Among refractive errors, both eyes astigmatism was the commonest 48 (36.5%) followed by both eyes simple myopia 44 (33.4 %) which was statistically significant with ocular headache (p=0.000). Ocular anomalies other than refractive error may coexist with headache complaints. Therefore, thorough ocular examination should be done in all patients suffering from headache.

Resumen

Background and aims Our departmental planning for COVID-19 was actioned a week before the lockdown (13th March 2020). We look at a 7- week lockdown activity for all scheduled outpatient clinics and urgent procedures. Methods and results A total of 2361 outpatient clinic slots (52.6% oncology slots and 47.4% benign urology slots) were scheduled during this period. The oncology slots included 330 (26.5%) flexible cystoscopy, 555 (44.7%) prostate cancer and 357(28.8%) non-prostate cancer slots. The benign urology slots included 323 (28.8%) andrology, 193 (17.2%) stones and 603 (54%) lower urinary tract symptoms (LUTS) slots. Of the total oncology outpatient slots (n = 1242), 66.3% were virtual consultations, 20% were face-to-face and 13.6% were cancelled. Of the total benign outpatient slots (n = 1119), 81% were virtual consultations, 9.7% were face-to-face and 9.3% were cancelled. A total of 116 anaesthetic surgical procedures were carried out, of which 54 (46.5%) were oncological procedures, 18 (15.5%) were benign urological procedures, and 44 (38%) were diagnostic procedures. Conclusions Hospitals and urologists can benefit from the model used by our hospital to mitigate the impact and prioritise patients most in need of urgent care. Reorganisation and flexibility of healthcare delivery is paramount in these troubled times and will allow clinical activity without compromising patient safety.

Resumen

Crytosporidium spp., Giardia duodenalis, and Enterocytozoon bieneusi are important diarrheal pathogens with a global distribution that threatens the health of humans and animals. Despite cattle being potential transmission hosts of these protozoans, the associated risks to public health have been neglected. In the present study, a total of 1155 cattle fecal samples were collected from 13 administrative regions of Heilongjiang Province. The prevalence of Cryptosporidium spp., G. duodenalis, and E. bieneusi were 5.5% (64/1155; 95% CI: 4.2–6.9), 3.8% (44/1155; 95% CI: 2.7–4.9), and 6.5% (75/1155; 95% CI: 5.1–7.9), respectively. Among these positive fecal samples, five Cryptosporidium species (C. andersoni, C. bovis, C. ryanae, C. parvum, and C. occultus), two G. duodenalis assemblages (E and A), and eight E. bieneusi genotypes (BEB4, BEB6, BEB8, J, I, CHS7, CHS8, and COS-I) were identified. Phylogenetic analysis showed that all eight genotypes of E. bieneusi identified in the present study belonged to group 2. It is worth noting that some species/genotypes of these intestinal protozoans are zoonotic, suggesting a risk of zoonotic disease transmission in endemic areas. The findings expanded our understanding of the genetic composition and zoonotic potential of Cryptosporidium spp., G. duodenalis, and E. bieneusi in cattle in Heilongjiang Province.

Resumen

Purpose Treatment of chronic-phase (CP) chronic myeloid leukemia (CML) with imatinib 400 mg/d can be unsatisfactory. Optimization of treatment is warranted. Patients and Methods In all, 1,014 newly diagnosed CP-CML patients were randomly assigned to imatinib 800 mg/d (n = 338), imatinib 400 mg/d (n = 325), or imatinib 400 mg/d plus interferon alfa (IFN-α; n = 351). Dose adaptation to avoid higher-grade toxicity was recommended. First primary end point was major molecular remission (MMR) at 12 months. Results A higher rate of MMR at 12 months occurred with tolerability-adapted imatinib 800 mg/d than with imatinib 400 mg/d (59% [95% CI, 53% to 65%] v 44% [95% CI, 37% to 50%]; P < .001) or imatinib 400 mg/d plus IFN-α (59% v 46% [95% CI, 40% to 52%]; P = .002). Median dose in the 800-mg/d arm was 628 mg/d with a maximum dose of 737 mg/d during months 4 to 6 and a maintenance dose of 600 mg/d. All three treatment approaches were well tolerated with similar grade 3 and 4 adverse events. Independent of treatment approach, MMR at 12 months showed better progression-free survival (99% v 94%; P = .0023) and overall survival (99% v 93%; P = .0011) at 3 years when compared with > 1% on the international scale or no MMR but showed no difference in 0.1% to < 1% on the international scale, which closely correlates with complete cytogenetic remission. Conclusion Treatment of early-phase CML with imatinib can be optimized. Early high-dose therapy followed by rapid adaptation to good tolerability increases the rate of MMR at 12 months. Achievement of MMR by month 12 is directly associated with improved survival.

Aim. To study the efficacy of shellfish dry extract with «Calcium-reparative» filler as a product of specialized medical nutrition to optimize bone metabolism.Methods. Total of 44 female patients aged from 49 to 71 years, mean age of 54.5±3.8 years, with a combination of several osteoporosis risk factors were involved. 72.7% of all patients complained of pain of varying severity in major joints, in the thoracic and lumbar spine. The patients were randomly divided into two groups - study group (29 patients) and control group (15 patients). Within 30 days, the participants of the study group received «Calcium-reparative» - a product created on the basis of natural biologically active compounds isolated from Far Eastern marine shellfish and purified Altai Shilajit. The efficacy of the product was assessed by means of standard questionnaires for the assessment of quality of life, 10-point visual analogue scale, biochemical laboratory tests. Measurement of serum osteocalcin was performed by ELISA, and immunochemical method - N-terminal propeptide of procollagen type I (the biomarker of bone tissue metabolism).Results. Adverse and allergic reactions to the product were not registered. Among those receiving the product 37.9% noted improvement of well-being and reduction of pain intensity from 6.9±0.45 to 4.28±0.74 points. In those receiving «Calcium-reparative» the level of synthesis of osteocalcin in the study group did not statistically significantly change and appeared to be 18.6±3.8 ng/ml. The increase in the concentration of procollagen type I from 20.9±3.0 ng/ml prior to administration of the therapeutic product to 37.6±5.8 ng/ml (t=0.006, p ≤0.001) after its administration was observed.Conclusion. Product of medical nutrition «Calcium-reparative» has the ability to stimulate the cells of bone tissue to synthesize bone matrix protein collagen type I.

Resumen

We sought to elucidate the relationship between albumin-bilirubin (ALBI) grade and non-protein respiratory quotient (npRQ) calculated by indirect calorimetry in chronic liver disease (CLD) patients (n = 601, median age = 63 years). Factors linked to npRQ < 0.85, which is reported to be an optimal cutoff point for the prognosis in liver cirrhosis (LC) patients, were also investigated using univariate and multivariate analyses. The median npRQ for all cases was 0.86. In total, 253 patients (42.1%) had npRQ < 0.85. The proportions of patients with npRQ < 0.85 in LC and non-LC patients were 51.9% (166/320) in LC patients and 31.0% (87/281) in non-LC patients (p < 0.0001). The median npRQ in ALBI grades 1, 2, and 3 for all cases were: 0.89, 0.85, and 0.82 (overall p < 0.0001). The proportions of patients with npRQ < 0.85 were 31.0% (71/229) in ALBI grade 1, 46.34% (152/328) in ALBI grade 2, and 68.18% (30/44) in ALBI grade 3 (overall p < 0.0001). In multivariate analyses of factors linked to npRQ < 0.85, ALBI grade 3 (p = 0.0095, hazard ratio = 3.242, ALBI grade 1 as a reference) was an independent predictor along with prothrombin time (p = 0.0139). In conclusion, ALBI grade can be a useful marker for npRQ in patients with CLDs.

Resumen

318 Background: Medical-related financial hardship (called financial toxicity) can negatively impact patient clinical outcomes and overall well-being. Routine financial toxicity screening is recommended to facilitate referrals to resources for patients experiencing, or at risk for, financial toxicity. The validated Comprehensive Score for Financial Toxicity (COST) tool is widely used in research to measure financial toxicity; however, its 11-question length and lack of standardized screening threshold make it challenging to implement in clinical practice. This analysis sought to develop and validate an abbreviated version of the tool, suitable for routine screening in clinical practice. Methods: The full COST was administered as part of clinical care from June 2022-August 2023. Patients receiving treatment for breast, gynecologic, thoracic, or gastrointestinal cancer at an urban comprehensive cancer center were queried via patient portal or in clinic. Using 38,330 observations, we calculated the correlation of abbreviated tools of varying length with the full COST score (0-44, lower scores=higher FT). We then used a validation dataset of 19,196 observations to assess the positive and negative predictive values (PPV, NPV) of an abbreviated tool against the full COST score, when compared to thresholds for risk previously used in the literature (score ≤15, ≤20). Results: Including two questions (Q3: “I worry about the financial problems I will have in the future as a result of my illness or treatment”; Q6: “I am satisfied with my current financial situation”) yielded r=0.922 correlation with the full COST. For this 2-item tool, PPV ranged from 74-91%, and NPV ranged from 91-98% when compared to the full COST tool. Table 1 shows the PPV and NPV of varying score thresholds for the abbreviated COST against full scores ≤15 and ≤20. Conclusions: Using a large and clinically diverse sample of patients with cancer,we demonstrate the predictive value of an abbreviated COST tool and show its approximate accuracy when compared to the full tool. Simplified, clinically integratedscreening for financial hardship can efficiently ensure appropriate intervention for patients experiencing medical-related financial hardship and can also be a first step toward mitigating hardship among those at risk for developing it.

Resumen

Aim: To evaluate the efficiency of Bayesian modeling software and first-order pharmacokinetic (PK) equations to calculate vancomycin area under the concentration-time curve (AUC) estimations. Methods: Unblinded, crossover, quasi-experimental study at a tertiary care hospital for patients receiving intravenous vancomycin. Vancomycin AUC monitoring was compared using Bayesian modeling software or first-order PK equations. The primary endpoint was the time taken to estimate the AUC and determine regimen adjustments. Secondary endpoints included the percentage of vancomycin concentrations usable for AUC calculations and acute kidney injury (AKI). Results: Of the 124 patients screened, 34 patients had usable vancomycin concentrations that led to 44 AUC estimations. Without electronic health record (EHR) integration, the time from assessment to intervention in the Bayesian modeling platform was a median of 9.3 min (quartiles Q1–Q3 7.8–12.4) compared to 6.8 min (Q1–Q3 4.8–8.0) in the PK equations group (p = 0.004). With simulated Bayesian software integration into the EHR, however, the median time was 3.8 min (Q1–Q3 2.3–6.9, p = 0.019). Vancomycin concentrations were usable in 88.2% in the Bayesian group compared to 48.3% in the PK equation group and there were no cases of AKI. Conclusion: Without EHR integration, Bayesian software was more time-consuming to assess vancomycin dosing than PK equations. With simulated integration, however, Bayesian software was more time efficient. In addition, vancomycin concentrations were more likely to be usable for calculations in the Bayesian group.

Resumen

Background:Imaging has been extensively used for the Calcium Pyrophosphate Deposition Disease (CPPD) diagnosis but the prevalence of joint calcifications at imaging in CPPD patients has not been thoroughly assessed.Objectives:This systematic literature review (SLR) is aimed to estimate the prevalence of calcium crystal deposition in peripheral joints by imaging in suspected or definite CPPD patients to establish relevant joints for CPPD monitoringMethods:After defining PICOs, Pubmed and Embase were searched from inception to October 2020 for identifying studies that evaluated the use of Conventional Radiography (CR), Ultrasound (US), Computed Tomography (CT) and Dual Energy Computed Tomography (DECT) in detecting calcifications at peripheral joints in patients with defined or probable CPPD. Search strategies based on MeSH terms and free text were applied. Six reviewers independently screened titles and abstracts, eligible article full texts were evaluated for inclusion and data extraction.Results:The SLR identified 1149 manuscripts. 524 papers entered in the full text evaluation and 181 articles were finally included. Considering excluded abstracts and full texts, 23 and 17 were excluded as duplicate, 156 and 9 for language, 171 and 48 for population, 171 and 20 for intervention, 57 and 117 for outcome, 47 and 70 for study type and 76 for full text unavailability. Among included, 41 papers considered patients with definite CPPD with a total population of 1239 patients, 908 cases and 331 controls and 140 papers referred to patients with suspected CPPD with a total population of 26785 patients, 2896 affected by CPPD and 23889 controls. The results about all joints are summarized in the Table 1. In patients with definite diagnosis, knee and wrist are the joints with the highest prevalence of calcifications at all imaging types, followed by hip and acromion-clavicular joint while in patients with suspected CPPD, the knee is the most prevalent followed by the wrist, hip and ankle (only sites with more than 50 patients assessed considered). The hand joints are characterized by CPPD lowest prevalence at imaging. Bilateral imaging findings varies depending on the technique used, the site and the patient’s type.Table 1.Definite CPPD DiagnosisKNEEWRISTHANDELBOWSHOULDERACHIPANKLEFOOTTMXRImaging positive cases/all cases330/584 57%214/409 52%43/158 27%54/212 25%65/249 26%37/84 44%140/293 48%30/255 12%15/59 25%0Cases positivebilaterally99/146 68%30/79 38%0/104/12 33%2/2 100%9/17 53%7/10 70%7/10 70%00USImaging positive cases/all cases155/252 62%86/118 75%4/42 9%2/2 100%0/304/30 13%47/80 59%30/255 12%15/59 25%0Cases positivebilaterally83/96 86%33/47 70%1/ 4 25%003/ 4 75%29/47 62%7/10 70%00CTImaging positive cases/all cases41/50 82%22/28 78%00000000Cases positivebilaterally27/30 90%000000000DECTImaging positive cases/all cases8/10 80%9/10 90%1/1 100%0000000Cases positivebilaterally001/1 100%0000000Suspected CPPD diagnosisKNEEWRISTHANDELBOWSHOULDERACHIPANKLEFOOTTMXRImaging positive cases/all cases1989/2442 81%549/1024 54%98/602 16%29/72 40%75/185 41%27/31 87%322/887 36%56/116 48%24/42 57%0Cases positive bilaterally611/1068 57%209/334 63%64/85 75%22/23 96%41/46 89%0/294/196 48%44/53 83%18/19 95%0USImaging positive cases/all cases241/261 93%125/185 68%2/39 5%1/1 100%4/12 33%02/2 100%27/78 35%8/37 22%0Cases positivebilaterally4/9 44%74/93 80%00000000CTImaging positive cases/all cases019/23 83%002/2 100%02/2 100%001/1 100%Cases positivebilaterally0000000001/1 100%DECTImaging positive cases/all cases1/1 100%2/2 100%00000000Cases positivebilaterally1/1 100%000000000Table 1 For each joint, are summarized the ratio between positive joints and overall evaluated joints and the ratio between the joints positive bilaterally and overall joints evaluated bilaterally.AC Acromion Clavicular, TM temporo mandibularConclusion:According to the results of this SLR, knees and wrists could be the sentinel joints for CPPD detection by imaging.Disclosure of Interests:None declared.

Resumen

606 Background: Only few randomized clinical trials have been conducted for second line therapy in advanced pancreatic cancer (APC). In these studies, elderly patients are poorly represented, even if the median age at diagnosis of APC is increasing; therefore, limited efficacy and safety data are available. Here, we present a retrospective monocentric analysis of second line chemotherapy in elderly patients treated at our Hospital. Methods: This study included patients with APC and aged>70 years old receiving a second-line chemotherapy for APC at our institution from March 2015 to August 2020. The primary endpoints were progression-free survival to second line (PFS2) and overall survival (OS); the secondary endpoint was safety. The Kaplan–Meier method was used to estimate efficacy outcome; log-rank test and Cox-regression model were used to compare the differences, considering a statistically significant p value < 0.05. Results: 169 pts affected with APC received first-line chemotherapy and 61 of them (36%) received second-line therapy. The median age at diagnosis was 74 Years (70-83), 31 (50%) were female; ECOG PS was 0-1 in 44 pts (59%), 41% had at least 2 comorbidities. The regimens of chemotherapy used were: mFOLFOX (28; 46%), Gemcitabine (11; 18%), Capecitabine (15; 24.6%), FOLFIRI (6; 9.8%), mFOLFIRINOX (1; 1.6%). 4 pts (6.6%) had a partial response and 22 (36.1%) had a stable disease, with a disease control rate of 42.7%. The median follow-up was 22.8 months; median PFS2 was 4.5 months (IC 95%: 2.5-6.5) and median OS was 15.4 months (IC 95%: 7.2-23.6). At the univariable analysis, there was a statistically significant difference in mPFS2 according to ECOG PS (0-1 vs 2: 5.3 [IC 95%: 3.5-7.0] vs 2.2 [IC 95%: 1.2-5.4] months; p 0.02) and number of metastatic sites at the beginning of second line therapy (1 vs 2 or more: 5.8 [IC 95%: 4.8-6.7] vs 3.4 [IC 95%: 3.1-3.8] months; p 0.006). At the multivariable analysis, both number of metastatic sites and ECOG PS were confirmed associated with mPFS2. Number of metastatic sites and ECOG PS were both also associated with mOS. No unexpected adverse events were reported, and no patients had to interrupt treatment due to toxicity. Conclusions: In our experience, only about a third of elderly pts with APC received second-line therapy; in these patients, ECOG PS, disease’s burden and the response to therapy are all positive prognostic factors. With regard to the safety profile, older age does not seem to negatively increase serious toxicities. In conclusion, elderly pts should not be precluded from an active treatment (also in later lines setting) and careful patients selection should guide treatment indication.

Resumen

Background:Behcet’s disease (BD) is a systemic disease that can affect vessels of any size and type. However, only limited cases of BD patients with vena cava involvement have been reported.Objectives:To investigate the clinical features and outcome of vena cava involvement in BD patients.Methods:We retrospectively reviewed the clinical data of BD patients with vena cava involvement in our institute from August 2001 to October 2019. The treatment and outcome of these patients were also analyzed.Results:Fifty BD patients with vena cava involvement were included. The median interval between BD onset and diagnosis of vena cava involvement was 2.8 (range 0-19.4) years. Superior vena cava (SVC) involvement was detected in 22 (44.0%) patients, and 21 patients had typical manifestations of SVC syndrome. Inferior vena cava (IVC) was detected in 35 (70.0%) patients, including 7 patients diagnosed with Budd-Chiari syndrome. Seven patients had both superior and inferior vena cava involvement. Forty-five (90.0%) patients had venous involvement other than vena cava, including 19 patients with common iliac thrombosis, 12 patients with common femoral vein thrombosis, 11 patients with external iliac vein thrombosis, etc. For the other BD manifestations, oral ulceration was presented in all patients, followed by genital ulceration (35, 70.0%), Erythema nodosum (27, 54.0%) and pathergy reaction (25, 50.0%). Thirteen (26%) patients had eye involvement. Ten (20%) patients had pleural and/or pericardial effusions. Eleven (22.0%) patients had pulmonary thromboembolism, and 4 (8.0%) patients had arterial involvement. Inflammatory markers were significantly elevated in 41 (82.0%) patients when the vena cava involvement developed, the mean ESR was 34.0±29.2mm/hr, and the median CRP level was 19.9(0.2-177.0) mg/L. The mean BDCAF2006 score of all patients was 4.6±1.6. Glucocorticoid was used in 47 (94.0%) patients after vena cava involvement was diagnosed, and cyclophosphamide was the first-choice immunosuppressant. Forty-one (82.0%) patients received anticoagulation treatment. Five patients had received placement of IVC filter, and 3 patients had taken balloon dilation of IVC. With a mean follow up of 4.1±3.8 years, 45 patients (90.0%) achieved clinical improvements, 6 patients (12.0%) had relapse of vascular involvement, 5 patients (10.0%) died. The respective estimated cumulative 1- and 5- years relapse-free rates were 90.9% and 83.1%, and the respective estimated 1- and 5- years survival rates were 95.9% and 90.1%.Conclusion:Vena cava involvement is a rare complication in BD patients. The prognosis of these patients is relatively optimistic after proper treatment. To the best of our knowledge, our study is the largest cohort of BD patients with vena cava involvement.References:[1]Y. Fei, X. Li, S. Lin et al.

Resumen

The aim of this study was to design a chemically defined medium for the vitrification of in vitro produced porcine blastocysts avoiding the use of serum or serum components. Cumulus–oocyte complexes were matured in vitro in NCSU-23 for 44 h and were inseminated with frozen–thawed spermatozoa. Presumptive zygotes were cultured for 16 h to assess in vitro fertilization (IVF) parameters (N = 200) or for 6 days (N = 600) in order to obtain blastocysts. For chemically delipidation, 10 μM forskolin was added to the culture medium on Day 5 of in vitro culture. On Day 2, embryos were evaluated for cleavage rate. On Day 6, embryos were assessed for blastocyst formation; only those blastocysts showing excellent morphological appearance were selected for vitrification. Blastocysts were vitrified using as basic medium TCM-199 HEPES supplemented with 20% of newborn calf serum (NBCS; n = 65), with 0.1% of polyvinyl alcohol (PVA; n = 64) or without additives (WA; n = 65). The OPS-vitrification and warming were performed as described by (Sanchez-Osorio et al. 2010 Theriogenology 73, 300–308) using 16% of Etylenglycol and 16% of dimetyl sulfoxide as final concentrations of cryoprotectants. Vitrified blastocysts were warmed and cultured in vitro for 24 h to assess their viability. Blastocysts that totally reformed their blastocoel cavity showing a normal or excellent morphology were considered viable. In addition, after in vitro culture vitrified-warmed viable embryos were fixed in 4% paraformaldehyde in PBS medium and stained with Hoechst 33342 in order to assess the total number of cells. Data were analysed by using the MIXED procedure of SPSS. The threshold for significance was set at P < 0.05. Results are expressed as least squares means ± SEM. The maturation, penetration, and monospermy rates were 98.5 ± 1.2%, 85.3 ± 3.6%, and 48.8 ± 5%, respectively. The efficiency of IVF (defined as the ratio of monospermic oocytes to the total number of inseminated oocytes) was 41.0 ± 4.9%. The values of cleavage rate at Day 2 and blastocysts formation rate were 67.8 ± 1.4% and 37.3 ± 1.6%, respectively. After vitrification and warming, similar survival rates were observed for NBCS (33.8 ± 5.9) PVA (40.6 ± 6.0), and WA (30.8 ± 5.9) groups. No significant differences were found for the total number of cells (ranged from 35.4 ± 6.8 to 50.8 ± 8.3) among vitrification groups. In conclusion, in vitro derived porcine blastocysts can be vitrified in the absence of serum and serum components. Furthermore, PVA is a suitable substitute for serum in vitrification solutions with no detrimental effect on the viability of in vitro produced pig blastocysts. This study was supported by the Seneca foundation of Murcia (GERM 04543/07).

Resumen

11001 Background: E-CMF [epirubicin (E) x 4 cycles every (q) 21 days (d), followed by classical CMF x 4 cycles q 28d] is established as highly effective adjuvant chemotherapy for early breast cancer (BC), reducing mortality by 30% compared with CMF alone [Poole NEJM 2006]. However, dose dense anthracycline-taxane schedules, accelerated with GCSF support, have been shown to be superior to conventional regimens [Citron JCO 2003, Burnell SABCS 2006]. Exploration of accelerated E-CMF is therefore of considerable interest. Methods: A non-randomised, multicenter trial was designed to explore the feasibility and tolerability of accelerated E-CMF chemotherapy for women with early BC. The primary endpoint was delivered dose intensity (DDI). The accrual target was 40 patients (pts). Pts were treated with 4 cycles E (100mg/m2) q 14d, with Pegfilgrastim (PF) (6mg sc) d2, followed by 4 cycles of Cyclophosphamide, Methotrexate, and 5-Fluorouracil (600/40/600mg/m2) administered intravenously d1 + 8, with PF d9, q 21d. Results: 44 pts were enrolled. Complete dose information from 40 pts and toxicity data from 336 cycles (44 pts) has been analysed. Median DDI was 96.7% of target. Delays of >2 d were recorded for 8% of cycles. Dose reductions were recorded in 4% of cycles. 90% of pts received >85% intended total dose and 85% of pts received >85% intended DDI. Percentage grade 2 and 3/4 toxicity reported per cycle were respectively: fatigue 34/12; all infections 7/4; emesis 19/4; bone pain 18/4; diarrhoea 7/3; dyspnoea 20/3; febrile neutropenia not applicable (na)/2; mucositis 12/0.3; and phlebitis 29/na. Hospitalisation occurred in 10% of cycles. One pt developed endocarditis in association with repeated line infections, and a further pt experienced severe delayed phlebitis requiring surgical intervention. Conclusions: Accelerated E-CMF with PF is feasible achieving high DDI in a majority of pts. Non-haematological toxicity was responsible for the majority of hospital admissions which were more frequent than anticipated. Relative efficacy of this regimen requires phase III evaluation. We have also completed a second study of accelerated E-CMF where 6 cycles of intensified CMF (800/50/600mg/m2) was delivered at 14 d intervals. No significant financial relationships to disclose.

Resumen

Intravenous albumin is recommended for hepatorenal disorders (HRD), but individuals who do not recover renal function may be at a high risk for pulmonary edema. We reviewed outcomes by the amount of albumin infused in 93 patients not receiving dialysis at admission but being treated with intravenous albumin for acute HRD at our institution. Absence of renal recovery was defined as no decrease in serum creatinine and requirement of dialysis during hospitalization, and partial renal recovery was defined as a decrease in serum creatinine but not to prehospitalization levels. Associations of clinical factors including total albumin infused, presence of renal recovery, and oliguria with the development of pulmonary edema during hospitalization were determined using logistic regression. Of the 93 patients, 20 patients had complete renal recovery, 17 patients had partial renal recovery, and 56 patients showed no renal recovery. Most patients received 300–600 g of albumin. Overall, 47.3% of patients developed pulmonary edema (n=44), but the risk was 75% in patients with oliguria on presentation and no renal recovery versus 17% in those with no oliguria and complete renal recovery (P<0.001). In the logistic regression model, oliguria (3.32; 95% confidence interval [CI]: 1.12, 9.81) and no renal recovery (3.38; 95% CI:1.24, 9.16) were each associated with higher odds of pulmonary edema after adjustment for covariates. No association was noted between total albumin infused and pulmonary edema. In summary, absence of renal recovery and oliguria in patients with HRD receiving intravenous albumin is associated with a higher risk of pulmonary edema.

Resumen

AimTo describe clinical features and outcomes of new-onset anterior uveitis associated with poorly controlled or undiagnosed diabetes mellitus.MethodsRetrospective analysis of 25 eyes of 18 patients (14 men, 4 women; mean age 44 years) who presented between December 2001 and October 2016 to the Kyorin Eye Center.ResultsOcular findings at presentation included posterior synechiae (15 eyes, 60%), anterior chamber fibrin (13 eyes, 52%), keratic precipitates (10 eyes, 40%), Descemet membrane folds (7 eyes, 28%) and hypopyon (3 eyes, 12%). Seven cases were bilateral. Intraocular pressure >21 mm Hg (7 eyes, 28%) and diabetic retinopathy (7 eyes, 28%, all non-proliferative) were also noted. The mean random blood glucose was 332 mg/dL (range 135–604 mg/dL) and the mean haemoglobin A1c was 12.6% (range 9.7%–16.7%). Seven patients (39%) were unaware of their hyperglycaemic state, and the remainder had either poor glucose control or had discontinued their diabetes treatment. Systemic examination and ancillary testing ruled out other possible causes of the uveitis. The ocular inflammation was managed in all cases using local corticosteroid therapy (drops and subconjunctival injections) in addition to internal medicine intervention for the diabetes. The best-corrected visual acuity (BCVA) was improved or maintained in all eyes at 3 months. The BCVA was ≤0.5 in two eyes due to both cataract and diabetic macular oedema.ConclusionsWe characterised new-onset anterior uveitis in 18 patients in association with poorly controlled or undiagnosed diabetes mellitus. The uveitis was managed in all cases with local corticosteroid therapy in addition to proper diabetes systemic treatment.

Resumen

Background Despite practice guidelines promoting delirium assessment in intensive care, few data exist regarding current delirium assessment practices among nurses and how these practices compare with those for sedation assessment. Objectives To identify current practices and perceptions of intensive care nurses regarding delirium assessment and to compare practices for assessing delirium with practices for assessing sedation. Methods A paper/Web-based survey was administered to 601 staff nurses working in 16 intensive care units at 5 acute care hospitals with sedation guidelines specifying delirium assessment in the Boston, Massachusetts area. Results Overall, 331 nurses (55%) responded. Only 3% ranked delirium as the most important condition to evaluate, compared with altered level of consciousness (44%), presence of pain (23%), or improper placement of an invasive device (21%). Delirium assessment was less common than sedation assessment (47% vs 98%, P < .001) and was more common among nurses who worked in medical intensive care units (55% vs 40%, P = .03) and at academic centers (53% vs 13%, P < .001). Preferred methods for assessing delirium included assessing ability to follow commands (78%), checking for agitation-related events (71%), the Confusion Assessment Method for the Intensive Care Unit (36%), the Intensive Care Delirium Screening Checklist (11%), and psychiatric consultation (9%). Barriers to assessment included intubation (38%), complexity of the tool for assessing delirium (34%), and sedation level (13%). Conclusions Practice and perceptions of delirium assessment vary widely among critical care nurses despite the presence of institutional sedation guidelines that promote delirium assessment.

ObjectiveTo explore the risk factors for ward and paediatric assessment unit (PAU) admissions from the emergency department (ED).DesignProspective observational study.Setting and patientsFebrile children attending a large tertiary care ED during the winter of 2014–2015.Main outcome measuresWard and PAU admissions, National Institute for Health and Care Excellence (NICE) guidelines classification, reattendance to the ED within 28 days and antibiotic use.ResultsA total of 1097 children attending the children's ED with fever were analysed. Risk factors for PAU admission were tachycardia (RR=1.1, 95% CI (1 to 1.1)), ill-appearance (RR=2.2, 95% CI (1.2 to 4.2)), abnormal chest findings (RR=2.1, 95% CI (1.2 to 4.3)), categorised as NICE amber (RR 1.7 95% CI (1.2 to 2.5)). There was a 30% discordance between NICE categorisation at triage and statistical internal validation. Predictors of ward admission were a systemic (RR=6.9, 95% CI (2.4 to 19.8)) or gastrointestinal illness (RR=3.8, 95% (1.4 to 10.4)) and categorised as NICE Red (RR=5.9, 95% CI (2.2 to 15.3)). Only 51 children had probable bacterial pneumonia (4.6%), 52 children had a proven urinary tract infection (4.2%), with just 2 (0.2%) positive blood cultures out of 485 (44%) children who received an antibiotic. 15% of all children reattended by 28 days and were more likely to have been categorised as Amber and had investigations on initial visit.ConclusionsRisk factors for PAU and ward admissions are different in this setting with high reattendance rates and very low proportion of confirmed/probable serious bacterial infections. Future studies need to focus on reducing avoidable admissions and antibiotic treatment.

Resumen

Background Prevalence of atopy, allergic diseases, and obesity are increasing. Atopy is an individu and/or familial tendency to sensitization in response to ordinary exposure to allergens. Obesity is defined as body mass index (BMI) greater or equal to 95 percentile. Research on association of BMI with atopy and allergic diseases in children were limited, with inconclusive results. Objective To assess association of BMI with atopy and allergic diseases in chidren.Methods A cross-sectional was conducted in school children aged 6-12 years in Lhokseumawe City, Aceh, June 2012. Children were assessed for BMI, skin prick test, and International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire. Statistical analyses included Chi-square, Fisher exact, and logistic regression.Results Children consisted of 137 (85.6%) normoweight, 12 (7.5%) overweight, and 11 (6.9%) obesity. Skin prick test results were positive in 44 (27.5%) and negative in 116 (72.5%) subjects. Allergic manifestations were allergic rhinitis (AR) 17 (10.6%), bronchial asthma 6 (3.8%), and atopic dermatitis (AD) 3 (1.9%). There was significant association of obesity with atopy, compared with normoweight (OR=3.78; 95%CI 1.08 to 13.19; P=0.037), but no significant association found when family history of atopy also assesed. There was significant association of obesity with bronchial asthma (OR=9.92; 95%CI 1.46 to 67.18; P=0.004) and AR (OR=6.49; 95%CI 1.64 to 25.66; P=0.015), compared with normoweight. Significant association of overweight with atopy and allergic disease was not found.Conclusion Obesity significantly associates with atopy, bronchial asthma, and AR, but overweight and normoweight do not.

Resumen

Background:To describe a comprehensive survey of the practice of electroconvulsive therapy (ECT) in Asia.Method:Between 2001 and 2003, a 29-item questionnaire was sent to 977 psychiatric facilities in 45 Asian countries.Results:Completed questionnaires were returned by 334 (34.2%) institutions in 29 (64.4%) countries. ECT was available in 257 institutions in 23 countries. During the year before the survey, 39,875 patients (62% male) received a mean of 7.1 ECT treatments. Most patients (73.1%) were 18-44 years old; few were < 18 (6.0%) or >64 (4.4%) years old. Indications for ECT were schizophrenia (41.8%), major depression (32.4%), mania (14.0%), catatonia (6.9%), drug abuse (1.8%), dysthymia (1.6%), and others. Brief-pulse ECT devices were used in only 103 (40.1%) institutions. Routine EEG monitoring was conducted in only 59 (23.0%) institutions. Bilateral electrode placement was invariable in 202 (78.6%) institutions. Unmodified ECT was administered to 22,194 (55.7%) patients at 141 (54.9%) institutions in 14 countries. Continuation ECT was available in only 115 (44.7%) institutions in 17 countries. No institution had a formal ECT training program.Conclusions:The practice of ECT in Asia may appear suboptimal: schizophrenia, not depression, is the commonest indication; most institutions offer sine-wave ECT; unmodified ECT is commonly administered; bilateral electrode placement is invariable in most institutions; EEG monitoring is uncommon; continuation ECT is infrequent; and no formal training in ECT is available. We speculate that the suboptimal practices reflect felt needs, and ground realities in standards of medical care in developing countries, rather than a misuse of ECT.

Resumen

852 Background: This study aimed to understand panitumumab (pmab) use in clinical practice for patients with wild-type RAS metastatic colorectal cancer (mCRC), in first-line (1L) with FOLFOX or second-line (2L) with FOLFIRI following fluoropyrimidine-based chemotherapy (excl. irinotecan). Methods: This is a combined analysis of two observational, non-interventional prospective cohort studies conducted in Germany/France (2012-2016) and Bulgaria/Czech Republic/Hungary (2013-2016). Results: Results are presented in the order of 1L FOLFOX (n = 332) followed by 2L FOLFIRI (n = 94). Patients received a median of 10 and 11.5 pmab infusions. The median duration of pmab exposure was 5.7 and 6.9 months (note that 53 and 10 patients continued pmab use after study end). The unadjusted overall response rate (complete or partial response) was 42% and 29%, based on 45% and 44% of patients with available response data post-baseline. In the 1L setting, resectability was achieved in 9%, not achieved in 42%, and unknown in 48%. Hospitalizations were reported for 100% and 99%, mostly cancer-related visits such as scheduled anticancer treatment (e.g. chemotherapy/pmab administrations), tumor assessment visits, or interventions; 93% in both groups reported outpatient, 66% and 60% inpatient visits. Conclusions: Overall, the study results show that treatment patterns and clinical efficacy of pmab in routine clinical practice were comparable to randomized controlled trials (RCTs). The ADR/SADR skin toxicity events are lower than expected based on findings from RCTs, however, similar findings have been shown in a previous observational study. More investigation is required to understand the reason for this.[Table: see text]

Resumen

Marine mammals are very diverse because of the oceanographic conditions of Mexican waters (where 36% of the current species worldwide are found); however, scientific research on many of these taxa is still at the basic stages. The goal of this study was to assess the scientific information available for these species and to determine research priorities through a GAP (from the acronym "Good", "Average", and "Poor”) analysis. Information from the abstracts of the meetings held by the Mexican Society of Marine Mammalogy (SOMEMMA) and online databases (SCOPUS and Web of Science) between 1998 and 2021 was analyzed using temporal (years), geographic (oceans or states), taxonomic (species), and thematic (topics) classifications. On average, of the 44 species included in the Mexican legislation, only 16 - included in 14 families (with most of the records) - are studied every year, Delphinidae (n = 500; 25.9%), Balaenopteridae (n = 335; 17.4%), and Otariidae (n = 316; 16.4%). The Gulf of California was the most studied region (35.4%), followed by the Northeast Pacific (19.3%), the Gulf of Mexico (15.5%), and the Caribbean Sea (6.9%). The most frequent topics were population ecology (32.9%), conservation (16.7%), and animal health (10.4%). A significant decrease in the taxonomic and thematic diversity of such studies has been noted since SOMEMMA meetings began to be held on a biennial basis. It is noteworthy that marine mammals are protected by Mexican Federal laws. However, stock assessments are not mandatory, therefore biological aspects and trends of several (mostly oceanic) species remain unknown in many places, especially in regions where academic and scientific institutions are not involved in marine science.

Resumen

Abstract Gamma-ray bursts (GRBs) 201015A and 201216C are valuable cases where very-high-energy (VHE) gamma-ray afterglows have been detected. By analyzing their prompt emission data, we find that GRB 201216C is an extremely energetic, long GRB with a hard gamma-ray spectrum, while GRB 201015A is a relative subenergetic, soft-spectrum GRB. Attributing their radio–optical–X-ray afterglows to the synchrotron radiation of the relativistic electrons accelerated in their jets, we fit their afterglow lightcurves with the standard external shock model and infer their VHE afterglows from the synchrotron self-Compton scattering process of the electrons. It is found that the jet of GRB 201015A is midrelativistic (Γ0 = 44), surrounded by a very dense medium (n = 1202 cm−3), and the jet of GRB 201216C is ultrarelativistic (Γ0 = 331), surrounded by a moderate dense medium (n = 5 cm−3). The inferred peak luminosity of the VHE gamma-ray afterglows of GRB 201216C is approximately 10−9 erg cm−2 s−1 at 57–600 s after the GRB trigger, making it detectable with the MAGIC telescopes at a high confidence level, even though the GRB is at a redshift of 1.1. Comparing their intrinsic VHE gamma-ray lightcurves and spectral energy distributions with GRBs 180720B, 190114C, and 190829A, we show that their intrinsic peak luminosity of VHE gamma-ray afterglows at 104 s after the GRB trigger is variable from 1045 to 5 × 1048 erg s−1, and their kinetic energy, initial Lorentz factor, and medium density are diverse among bursts.

Resumen

This study evaluated the effects of β-hydroxy-β-methylbutyrate free acid (HMB-FA) and calcium salt (HMB-Ca) on strength, hypertrophy, and markers of muscle damage. In this randomized, double-blind, placebo-controlled study, 44 resistance-trained men (age: 26 ± 4 years; body mass: 84.9 ± 12.0 kg) consuming ≥1.7 g·kg−1·day−1 of protein received HMB-FA (3 g/day; n = 14), HMB-Ca (3 g/day; n = 15), or placebo (PL; cornstarch, 3 g/day; n = 15) for 12 weeks, while performing a periodized resistance training program. Before and after intervention, lean body mass (measured with dual X-ray absorptiometry), maximal dynamic strength (one-repetition maximum), knee extension maximal isometric strength (maximal voluntary isometric contraction [MVIC]), cross-sectional area (measured with ultrasound), and muscle soreness were assessed. MVIC was also measured 48 hr after the first and the last training sessions. All groups increased lean body mass (main time effect: p < .0001; HMB-FA: 1.8 ± 1.8 kg; HMB-Ca: 0.8 ± 1.4 kg; PL: 0.9 ± 1.4 kg), cross-sectional area (main time effect: p < .0001; HMB-FA: 6.6 ± 3.8%; HMB-Ca: 4.7 ± 4.4%; PL: 6.9 ± 3.8%), one-repetition maximum bench press (main time effect: p < .0001; HMB-FA: 14.8 ± 8.4 kg; HMB-Ca: 11.8 ± 7.4 kg; PL: 11.2 ± 6.6 kg), MVIC (main time effect: p < .0001; HMB-FA: 34.4 ± 39.3%; HMB-Ca: 32.3 ± 27.4%; PL: 17.7 ± 20.9%) after the intervention, but no differences between groups were shown. HMB-FA group showed greater leg press strength after the intervention than HMB-Ca and PL groups (Group × Time interaction: p < .05; HMB-FA: 47.7 ± 31.2 kg; HMB-Ca: 43.8 ± 31.7 kg; PL: 30.2 ± 20.9 kg). MVIC measured 48 hr after the first and the last sessions showed no attenuation of force decline with supplementation. Muscle soreness following the first and last sessions was not different between groups. The authors concluded that neither HMB-Ca nor HMB-FA improved hypertrophy or reduced muscle damage in resistance-trained men undergoing resistance training ingesting optimal amounts of protein. HMB-FA but not HMB-Ca resulted in a statistically significant yet minor improvement on leg press one-repetition maximum.

Resumen

786 Background: Patients with anal cancer (AC) can achieve long-term disease control with chemoradiation (CRT), however, the treatment has serious adverse effects. Most patients with AC are ≥65 but little is known about cancer outcomes in this population. Frailty measures have been proposed to determine the risk of treating older adults. The purpose of this study was to evaluate the impact of age and frailty on outcomes in patients with AC. Methods: A retrospective review was performed of patients age ≥65 with non-metastatic AC treated from 2007-2016 at Princess Margaret Cancer Centre. A 44-item Cumulative Deficit Score was constructed to quantify frailty as per the Rockwood model. The impact of age and frailty on treatment toxicity and overall survival (OS) was analyzed using multivariable logistic regression and survival models, respectively, adjusting for ECOG performance status (PS), stage and treatment modality. Results: Among 92 patients, median age was 72 and 42.4% were age ≥75. Seventy (76.1%) patients were treated with CRT and 17 with radical radiotherapy (RT). After a median follow-up of 34.9 mo (range 0.5-103.9) 34 patients died – 16 from metastatic AC, 16 from other or unknown causes, and 2 treatment-related deaths. For patients treated with CRT or RT (N = 87), 53 (60.9%) required treatment modification due to toxicity. Twenty patients (22.9%) had an emergency room visit or hospitalization. Frailty did not significantly increase the risk of toxicity in multivariable analysis (OR 1.9, 95% CI 0.35-10.8). Treatment with CRT increased the risk of toxicity compared to RT alone (OR 9.5, 95% CI 1.7-53.8). Patients ≥75 had shorter OS on univariable analysis (HR 1.9, 95% CI 1.0-3.8) but not on multivariable modeling (HR 1.5, 95% CI 0.72-3.4). Factors associated with shorter OS were increased frailty (HR 3.8 CI 1.4-10.2) and ECOG ≥2 (HR 3.9, 95% CI 1.7-9.1). There was good discrimination of the model with a C-statistic of 0.77. Conclusions: Older adults with AC experience a high rate of treatment toxicity especially with CRT relative to RT alone. OS was significantly associated with frailty as well as PS but not age. Frailty assessment may improve treatment planning and understanding survival for older patients with AC.
