Background During the COVID-19 response, nonclinical essential workers usually worked overtime and experienced significant work stress, which subsequently increased their risk of mortality due to cardiovascular diseases, stroke, and pre-existing conditions. Deaths on duty, including deaths due to overwork, during the COVID-19 response were usually reported on web-based platforms for public recognition and solidarity. Although no official statistics are available for these casualties, a list of on-duty deaths has been made publicly available on the web by crowdsourcing. Objective This study aims to understand the trends and characteristics of deaths related to overwork among the frontline nonclinical essential workers participating in nonpharmaceutical interventions during the first wave of COVID-19 in China. Methods Based on a web-based crowdsourced list of deaths on duty during the first wave of the COVID-19 response in China, we manually verified all overwork-related death records against the full-text web reports from credible sources. After excluding deaths caused by COVID-19 infection and accidents, a total of 340 deaths related to overwork among nonclinical essential workers were attributed to combatting the COVID-19 crisis. We coded the key characteristics of the deceased workers, including sex, age at death, location, causes of death, date of incidence, date of death, containment duties, working area, and occupation. The temporal and spatial correlations between deaths from overwork and COVID-19 cases in China were also examined using Pearson correlation coefficient. Results From January 20 to April 26, 2020, at least 340 nonclinical frontline workers in China were reported to have died as a result of overwork while combatting COVID-19. The weekly overwork mortality was positively correlated with weekly COVID-19 cases (r=0.79, P<.001). Two-thirds of deceased workers (230/340, 67.6%) were under 55 years old, and two major causes of deaths related to overwork were cardiovascular diseases (138/340, 40.6%) and cerebrovascular diseases (73/340, 21.5%). Outside of Hubei province, there were almost 2.5 times as many deaths caused by COVID-19–related overwork (308/340, 90.6%) than by COVID-19 itself (n=120). Conclusions The high number of deaths related to overwork among nonclinical essential workers at the frontline of the COVID-19 epidemic is alarming. Policies for occupational health protection against work hazards should therefore be prioritized and enforced.

Aims During the COVID-19 pandemic, many patients continue to require urgent surgery for hip fractures. However, the impact of COVID-19 on perioperative outcomes in these high-risk patients remains unknown. The objectives of this study were to establish the effects of COVID-19 on perioperative morbidity and mortality, and determine any risk factors for increased mortality in patients with COVID-19 undergoing hip fracture surgery. Methods This multicentre cohort study included 340 COVID-19-negative patients versus 82 COVID-19-positive patients undergoing surgical treatment for hip fractures across nine NHS hospitals in Greater London, UK. Patients in both treatment groups were comparable for age, sex, body mass index, fracture configuration, and type of surgery performed. Predefined perioperative outcomes were recorded within a 30-day postoperative period. Univariate and multivariate analysis were used to identify risk factors associated with increased risk of mortality. Results COVID-19-positive patients had increased postoperative mortality rates (30.5% (25/82) vs 10.3% (35/340) respectively, p < 0.001) compared to COVID-19-negative patients. Risk factors for increased mortality in patients with COVID-19 undergoing surgery included positive smoking status (hazard ratio (HR) 15.4 (95% confidence interval (CI) 4.55 to 52.2; p < 0.001) and greater than three comorbidities (HR 13.5 (95% CI 2.82 to 66.0, p < 0.001). COVID-19-positive patients had increased risk of postoperative complications (89.0% (73/82) vs 35.0% (119/340) respectively; p < 0.001), more critical care unit admissions (61.0% (50/82) vs 18.2% (62/340) respectively; p < 0.001), and increased length of hospital stay (mean 13.8 days (SD 4.6) vs 6.7 days (SD 2.5) respectively; p < 0.001), compared to COVID-19-negative patients. Conclusion Hip fracture surgery in COVID-19-positive patients was associated with increased length of hospital stay, more admissions to the critical care unit, higher risk of perioperative complications, and increased mortality rates compared to COVID-19-negative patients. Risk factors for increased mortality in patients with COVID-19 undergoing surgery included positive smoking status and multiple (greater than three) comorbidities.

<P>Objective: MicroRNA (miR)-340-5p has been identified to play a key role in several cancers. However, the function of miR-340-5p in skin fibroblasts remains largely unknown. </P><P> Methods: Gain of function experiments were performed by infecting normal skin fibroblast cells with a lentivirus carrying 22-bp miR-340-5p. Cell proliferation was detected by Cell Counting Kit-8 (CCK-8) assay. To uncover the mechanisms, mRNA-seq was used. Differentially expressed mRNAs were further determined by Gene Ontology and KEGG pathway analyses. The protein levels were analysed by Western blotting. A dual-luciferase reporter assay was used to detect the direct binding of miR-340-5p with the 3'UTR of Kruppel-like factor 2 (KLF2). </P><P> Results: MiR-340-5p lentivirus infection suppressed normal skin fibroblast proliferation. The mRNAseq data revealed that 41 mRNAs were differentially expressed, including 22 upregulated and 19 downregulated transcripts in the miR-340-5p overexpression group compared with those in the control group. Gene Ontology and KEGG pathway analyses revealed that miR-340-5p overexpression correlated with the macromolecule biosynthetic process, cellular macromolecule biosynthetic process, membrane, and MAPK signalling pathway. Bioinformatics analysis and luciferase reporter assays showed that miR-340-5p binds to the 3'UTR of KLF2. Forced expression of miR-340-5p decreased the expression of KLF2 in normal skin fibroblasts. Overexpression of KLF2 restored skin fibroblast proliferation in the miR-340-5p overexpression group. </P><P> Conclusion: This study demonstrates that miR-340-5p may suppress skin fibroblast proliferation, possibly through targeting KLF2. These findings could help us understand the function of miR-340-5p in skin fibroblasts. miR-340-5p could be a therapeutic target for preventing scarring.</P>

The coronavirus pandemic has affected more than 150 million people, while over 3.25 million people have died from the coronavirus disease 2019 (COVID-19). As there are no established therapies for COVID-19 treatment, drugs that inhibit viral replication are a promising target; specifically, the main protease (Mpro) that process CoV-encoded polyproteins serves as an Achilles heel for assembly of replication-transcription machinery as well as down-stream viral replication. In the search for potential antiviral drugs that target Mpro, a series of cembranoid diterpenes from the biologically active soft-coral genus Sarcophyton have been examined as SARS-CoV-2 Mpro inhibitors. Over 360 metabolites from the genus were screened using molecular docking calculations. Promising diterpenes were further characterized by molecular dynamics (MD) simulations based on molecular mechanics-generalized Born surface area (MM-GBSA) binding energy calculations. According to in silico calculations, five cembranoid diterpenes manifested adequate binding affinities as Mpro inhibitors with ΔGbinding < −33.0 kcal/mol. Binding energy and structural analyses of the most potent Sarcophyton inhibitor, bislatumlide A (340), was compared to darunavir, an HIV protease inhibitor that has been recently subjected to clinical-trial as an anti-COVID-19 drug. In silico analysis indicates that 340 has a higher binding affinity against Mpro than darunavir with ΔGbinding values of −43.8 and −34.8 kcal/mol, respectively throughout 100 ns MD simulations. Drug-likeness calculations revealed robust bioavailability and protein-protein interactions were identified for 340; biochemical signaling genes included ACE, MAPK14 and ESR1 as identified based on a STRING database. Pathway enrichment analysis combined with reactome mining revealed that 340 has the capability to re-modulate the p38 MAPK pathway hijacked by SARS-CoV-2 and antagonize injurious effects. These findings justify further in vivo and in vitro testing of 340 as an antiviral agent against SARS-CoV-2.

Abstract Introduction Our objective was to document the incidence of COVID-19 in vaccinated health care professionals and related personnel. Method We conducted an online survey to ascertain the incidence of COVID-19 symptoms, reverse transcriptase polymerase chain reaction (RT-PCR) positivity, effect on normal activity, need for anti-COVID-19 medication, hospitalization, and death among individuals who had completed both doses of COVID vaccination at least 2 weeks earlier. Results A total of 351 unique valid responses were received. Among the 340 people who had been vaccinated in India, 5% (17/340) had COVID-19 symptoms, 4.7% (16) became COVID-19 RT-PCR positive, 12 (3.5%) had sickness preventing normal daily activity, 2.65% (9) required anti-COVID-19 medication, and 1.18% (4) required hospitalization. Among family members living with the survey responders, the corresponding incidence was even lower. There was one death in this group. Discussion Being health care professionals, the responders would be at higher risk of daily exposure to COVID-19. Even in this high risk group, the vaccine efficacy is good. Vulture journalists should stop spreading fake news and misinformation that makes people hesitate taking the vaccine or be afflicted analysis paralysis. Every person who chooses to remain unvaccinated increases the risk for our entire community. We also need to follow universal precautions (wearing mask, physical distancing, handwashing) diligently without letting down our guard.

Статья посвящена вопросам изучения структуры меланоидинов - соединений, обеспечивающих цветообразование пива. Поставленная цель исследования - изучение цветовых характеристик меланоидинов, их состава и вклада в интенсивность окраски пива - обоснована субъективным представлением о методах измерения цвета. Реализацию поставленной цели осуществляли с помощью методов анализа, принятых в отрасли. Авторами сняты спектральные характеристики экстрактов меланодиинов с максимумами при 340 нм для двух образцов светлого пива, 340-350 нм для одного образца темного пива и 340-400 нм - для другого образца темного пива. Приведенные результаты исследования состава экстрактов меланоидинов из образцов пива, полученного из разных типов зернового сырья, показывают различия в характере светопоглощения. Полученные авторами соотношения углеводной и азотосодержащей составляющей меланоидинов пива не показали корреляции с содержанием экстрактивности начального сусла, цветом пива и общим содержанием меланоидинов в пиве. Соотношения редуцирующих и азотистых соединений в экстрактах меланоидинов были сгруппированы относительно цвета исходного пива. Показано, что в светлых сортах пива соотношение редуцирующих и азотистых соединений составляет 1:13-1:22 и коррелирует с типом применяемого более окрашенного солода, а в темных сортах пива - 1:10-1:19. The article is devoted to the study of the melanoidin structure - compounds that provide the color formation of beer. The stated goal is to study the color characteristics of melanoidins, their composition and contribution to the intensity of the color of beer - is justified by a subjective idea of color measurement methods. The implementation of the goal was carried out using the methods of analysis adopted in the industry. The authors recorded the spectral characteristics of melanoidin extracts with maxima at 340 nm for two samples of light beer, 340-350 nm for one sample of dark beer and 340-400 nm for another sample of dark beer. The results of studying the composition of melanoidin extracts from beer samples obtained from different types of grain raw materials show differences in the nature of light absorption. The ratios of the carbohydrate and nitrogen-containing components of beer melanoidins obtained by the authors did not show a correlation with the extract content of the initial wort, the color of beer, and the total content of melanoidins in beer. The ratios of reducing and nitrogen compounds in melanoidin extracts were grouped relative to the color of the original beer. It is shown that in light beers the ratio of reducing and nitrogenous compounds is 1:13-1:22 and correlates with the type of more colored malt used, and in dark beers it is 1:10-1:19.

Abstract Background SOTs (SOT) recipients with COVID-19 are considered to be at high risk of severe clinical outcomes. Several descriptive studies have reported a high frequency of intensive care unit admission and death rates. There is a lack of evidence regarding the best approach for immunosuppressive therapy in SOT recipients with COVID-19. Methods We performed a single-centered, retrospective, observational study of all SOT recipients with SARS-CoV-2 confirmed infection RT-PCR from nasopharyngeal swab specimens who were admitted to the emergency department from March 25 to September 1, 2020. Glucocorticoid therapy was administered according to the criteria of the attending physician. We classified glucocorticoid dose as low dose therapy if the patient received dexamethasone 6 mg/day or methylprednisolone 40 mg/day, and a high dose if the patient received methylprednisolone 80–160 mg/day. Specimens collected within the first 48 hours were defined coinfection, while specimens collected after 48 hours were defined as hospital-acquired superinfection. Results Of a total of 43 SOT recipients with COVID-19, 17 (39%) required intensive care unit admission. 32 (74.4%) required glucocorticoid therapy: 13 received low dose and 19 high dose. 15 (34.8%) had secondary infections. A total of 12 (27.9%) presented hospital-acquired bacterial superinfections, mostly caused by P. aeruginosa, most of isolations were from respiratory tract cultures. The median time from hospital admission to superinfection diagnosis was 9 (7-13) days. Community-acquired co-infection at COVID-19 diagnosis was documented only in 3 (6.9%) patients, mostly caused by K. Pneumoniae, all isolations were from urine culture. Glucocorticoid therapy was indicated in 32 (80%) patients, 19 received high dose and 13 low doses. Overall hospital mortality was 17.5%. ICU mortality was 41%. Overall mortality in the high dose steroids group was 37 % vs . 0% in the low dose group. Conclusion Our results showed a higher frequency of superinfection in SOT recipients with COVID-19 compared to previous reports, and higher ICU mortality. Further studies are needed to establish the best approach for glucocorticoid therapy in SOT recipients with COVID-19. Disclosures All Authors: No reported disclosures

Background The coronavirus disease (COVID-19) is expected to have widespread and pervasive implications for mental health in terms of deteriorating outcomes and increased health service use, leading to calls for empirical research on mental health during the pandemic. Internet-based psychological measurement can play an important role in collecting imperative data, assisting to guide evidence-based decision making in practice and policy, and subsequently facilitating immediate reporting of measurement results to participants. Objective The aim of this study is to use an internet-based mental health measurement platform to compare the mental health profile of community members during COVID-19 with community members assessed before the pandemic. Methods This study uses an internet-based self-assessment tool to collect data on psychological distress, mental well-being, and resilience in community cohorts during (n=673) and prior to the pandemic (two cohorts, n=1264 and n=340). Results Our findings demonstrate significantly worse outcomes on all mental health measures for participants measured during COVID-19 compared to those measured before (P<.001 for all outcomes, effect sizes ranging between Cohen d=0.32 to Cohen d=0.81. Participants who demonstrated problematic scores for at least one of the mental health outcomes increased from 58% (n=197/340) before COVID-19 to 79% (n=532/673) during COVID-19, leading to only 21% (n=141) of measured participants displaying good mental health during the pandemic. Conclusions The results clearly demonstrate deterioration in mental health outcomes during COVID-19. Although further research is needed, our findings support the serious mental health implications of the pandemic and highlight the utility of internet-based data collection tools in providing evidence to innovate and strengthen practice and policy during and after the pandemic.

Hallamos resultados similares en los antecedentes de abortos y cesáreas, así como el sexo del recién nacido. Conclusiones: La diferencia entre el peso promedio de los recién nacidos a término es alrededor de 55 g en las primeras 4 ciudades, pero se incrementa entre Puno y Cerro de Pasco a aproximadamente 250 g. Se observa una reducción significativa por encima de los 2 340 m y es mucho más marcado por encima de los 4 000 m. Los neonatos masculinos tienen más peso que los femeninos a diferentes niveles de altura.

Context Athletic trainers (ATs) are heavily involved in concussion assessment and return-to-play (RTP) decision making. Despite ATs' crucial role, few researchers have directly examined ATs' knowledge of concussions or whether concussion knowledge or clinical experience affects clinical concussion-management practices. Objective To determine the overall concussion knowledge of ATs and whether concussion knowledge and clinical experience affect concussion-assessment and -management practices. Design Cross-sectional study. Setting Online survey. Patients or Other Participants Random convenience sample of 8725 (15.0% response rate [1307/8725]; certified, 14.8 ± 10.6 years) ATs surveyed from the National Athletic Trainers' Association membership. Main Outcome Measure(s) The survey collected demographics, concussion-assessment and -management tools used, and concussion knowledge (patient-clinician scenarios, signs and symptoms recognition). We used multiple logistic regression models to determine the odds ratios (ORs) for using assessment and management tools based on signs and symptoms recognition and years of clinical experience. Results The ATs correctly identified 78.0% ± 15.1% of concussion signs and symptoms. Approximately 46% (357/770) of ATs indicated an athlete could RTP if the athlete stated he or she had a “bell rung.” Every additional year of clinical experience decreased the odds of using standardized sideline-assessment tools by 3% (OR = 0.97, 95% Confidence Interval [CI] = 0.95, 0.99). The odds of using standardized sideline tools (OR = 0.98, 95% CI = 0.96, 0.99) and symptom checklists (OR = 0.98, 95% CI = 0.97, 0.99) for RTP assessment were significantly decreased for each additional year of clinical experience. No other tools used for RTP assessment were influenced by signs and symptoms recognition (P ≥ .136) or clinical experience (P ≥ .158). Conclusions The ATs with greater clinical experience had lower odds of using concussion-assessment and -management tools. Athletic trainers should frequently review and implement current consensus guidelines into clinical practice to improve concussion recognition and prevent improper management.

BACKGROUND: COVID-19 has affected research and students all over the world. Ongoing studies have been disrupted and upcoming studies cannot begin until they are adapted to the new reality. METHODS: This is a cross-sectional study. The study was realized during the period March-May 2020. This study was included n = 340 (nurse. physiotherapy, midwife) students. In this study, we conduct a short questionnaire about the perception of quality of e-learning. The study was conducted with students of University of Shkodra, Department of Nursing. The survey was performed through an online form and all participants were virtual and anonym and were free to write everything about the quality of learning, methodology of teaching, and the difficulty during this process. RESULTS: In this study, n = 340 students were included. One hundred and fifty eight of them were attending their nurse studies, 40 physiotherapy, 72 midwife, and 70 were master students. Thirty-seven percentage of the participants were nurse students in their 2nd year of studies, 10% were nurse students in the 3rd year of their bachelor degree, 21% of students were midwifes in the 2nd year of the bachelor degree, 12% physiotherapy and (20%) in master’s degree. Eighty-three percentage of students were female and 17% were male. The student included were 19–25-year old, minimum 19-year old, maximum 25-year old, average 23-year old. The most part of them were from rural areas (70%). CONCLUSIONS: The majority of students were satisfied with the methodology of teachers, but they have identified a lot of problems and difficulties during this time. Most part of the problems was identified as technical and economic related with the students and professors.

Ore bearing porphyritic systems of Sikhote-Alin form linear zones in Cretaceous volcanic belt. They are limited to zones of tectonic disturbances at Moho depths of 19-25 mi (30-40 km). Pacific slab lies at around 340 miles (548 km) below the volcanic belt, which matches the slab depth of porphyritic deposits formation belts in the Andes and Indonesia-Tonga region. Formation of porphyry copper systems is linked to the processes of metalliferous fluids intrusion at slab destruction areas near asthenosphere.

Abstract Prothrombin 20210G>A and factor V Leiden are common prothrombotic mutations in whites for which founder effects have been established. In this study, we analyzed the frequencies of 5 single nucleotide polymorphisms (SNPs) and 9 microsatellites flanking the prothrombin gene (F2) in 88 homozygotes for 20210A and 66 homozygotes for 20210G. For estimating the age of the prothrombin 20210G>A mutation, we used the DMLE+2.0 program, which analyzed linkage disequilibria between the mutation and the multiple markers that had been assessed. This analysis yielded an age estimate of 23 720 years (95% credible set, 19 080-31 340 years). A similar analysis by the DMLE+2.0 program was performed on 5 SNPs from previously studied homozygotes for factor V Leiden and controls that yielded an age estimate of 21 340 years (95% credible set, 16 880-29 480 years). The occurrence of the 2 mutations in whites toward the end of the last glaciation and their presently wide distribution in whites suggest selective evolutionary advantages for which some evidence was reported (diminished blood loss) or is controversial (protection against infections).

Background:Circulating anti-drug antibodies (ADAs) are detectable approximatively in 33% of adalimumab treated rheumatoid arthritis (RA) patients, often within the first 6 months of therapy1-2. Classically, circulating ADAs associate with their specific drugs to form immune complexes, increasing drug clearance, and by this mechanism reducing therapeutic effect3. B cell involvement leading to ADAs production is not yet well established.Objectives:To study early ADAs formation according to clinical response to an adalimumab therapy in RA patients and the relationship between ADAs and circulating B cell subsets.Methods:28 RA patients and 13 healthy controls were included. Patients all presented inadequately controlled RA under conventional treatment, were naive of biotherapies, and started an adalimumab treatment at baseline (M0). Responder status was determined according to the DAS28CRP score (<or>3.2) at 3 (M3) and 6 months (M6). ADAs plasma concentration >10pg/mL at M3 defined the immunized patient group. Circulating B cell subsets were quantified by flow cytometry at M0 and M3.Results:11 (42.3%) patients were immunized at M3. Among them, 4 (36.4%) were responders at M6 and 7 (63.6%) were non-responders. Presence and concentration of ADAs at M3 was associated to non-responder status at M6 (p=0.043; p=0.042). Immunized patients had lower transitional B cells count at M0 compared to non-immunized patients (p=0.031).Conclusion:A high but classical proportion of RA patients developed ADAs after only 3 months of adalimumab treatment. This immunization was associated to non-responder status at M6 and to a low blood transitional B cells count at baseline. Our results suggest transitional B cells implication inRA activity and biotherapy resistance due to immunization. Low concentrations of transitional B cells could be an early biomarker of immunization process against adalimumab.References:[1]Bartelds GM et al. JAMA. 2011[2]Moots RJ et al.

The coronavirus disease of 2019 (COVID-19) discovered in China in early December 2019. The Saudi Food and Drug Authority approved the registration of the Pfizer-BioNTech COVID-19 vaccine in Saudi Arabia on December 10, 2020, and on May 10, 2021, Pfizer-BioNTech was given emergency authorization for use of the vaccine in children aged 12 to 15 years. Saudi Arabia’s Ministry of Health started the vaccination phase for ages 12 to 18 years for the Pfizer-BioNTech COVID-19 vaccine on June 27, 2021. An insulin-dependent diabetic 15-year-old female patient admitted to the medical ward diagnosed with acute pancreatitis nine days after being administered her first dose of the Pfizer-BioNTech COVID-19 vaccine. She presented with an amylase level of 340 U/L, lipase level of 937 U/L. She was discharged after eight days of hospitalization with no complications. Medical investigations were unable to link the diagnosis to any known etiology. Medical journals have reported numerous cases of acute pancreatitis in the adult population after Pfizer-BioNTech COVID-19 vaccination. We believe that our case is the first to present with acute pancreatitis after the first dose of the Pfizer-BioNTech COVID-19 vaccine in a teenager population.

Обнаружено, что все диаграммы нагружения имеют аномальный вид и содержат участки резкого и плавного снижения деформирующих напряжений. Моделирование кривых псевдоупругой деформации в рамках теории размытых мартенситных переходов, описывающей не только равновесие фаз, но и кинетику перехода между ними, показало, что ответственными за необычный вид диаграмм сжатия могут быть упругие межфазные напряжения, возникающие при характерных для этого сплава мартенситных реакциях Ll2->14M и 14M-> Ll0.

<p><strong>Background and Objective</strong>: The Coronavirus disease 2019 (COVID-19) pandemic has affected more than four million people in 213 countries. Health care workers (HCWs) who deal with COVID-19 patients have a high chance of getting infected. They have got valid concerns regarding their own health as well as the impact it can have on the wellbeing of their family and acquaintances. The current study aims to assess the prevalence of psychological problems among HCWs during the COVID-19 pandemic. <strong>Methods:</strong> A cross-sectional study was conducted among HCWs of Wah Medical College and Pakistan Ordnance Factories (POF) Hospital Wah Cantt from 1st May 2020 to 7th May 2020 after an ethical approval by ethical review board. A total of 340 HCWs participated by filling an online questionairre; questions on demographic profile and validated Depression, Anxiety and Stress Scale–21 (DASS-21) score were included. Frequency of depression, anxiety and stress and mean DASS-21 scores between house officers and all other healthcare workers and between Medicine and allied department and other departments was assessed. Data was analysed using Statistical Package for the Social Sciences (SPSS)-23. P-value ≤ 0.05 was considered statistically significant. <strong>Results:</strong> Among 340 HCWs majority i.e. 66.8% were less than 35 years of age and the mean age of participants was 40.65 ± 11.64 years. There was a female proponderance with a F:M ratio of 1.7:1. Most (55.3%) of the participants were single and there was a high percentage of house officers with 45% among all. The overall prevalence of depressiom, anxiety and stress among all HCWs was 32.9%, 25% and 23.5% respectively. The depression, anxiety and stress among house officers than other HCWs and higher prevalence in Medicine and Allied Departments than other departments. <strong>Conclusion:</strong> As the global threat of COVID-19 continues to emerge, it is important not to underestimate the psychological impact of this pandemic on HCWs. Interventions and support to especially vulnerable groups of HCWs will help improve psychological health, which in turn will help improve the quality of patient care.</p>

In the context of the evolving current COVID-19 pandemic, influenza vaccination among the public and health care workers is of particular importance. There are sparse data on the influenza vaccination coverage among health care workers amid COVID-19 pandemic. We aimed to study possible factors associated with influenza vaccination coverage among Greek physicians, dentists, and pharmacists during the flu season 2020–2021. We formulated the hypothesis that COVID-19 pandemic exerted a positive impact on the influenza vaccination coverage of health care workers. An online survey was conducted among the members of the Larissa, (Thessaly, Central Greece) Medical, Dentists, and Pharmacists Associations. The influenza vaccination coverage was 74% (251/340). Acceptance of COVID-19 vaccination coverage was the only factor independently associated with the likelihood of influenza vaccination coverage. In conclusion, we report here a considerable improvement of the influenza vaccination coverage among HCWs and especially among physicians. Acceptance of COVID-19 vaccination was the only predictor of influenza vaccination coverage. This finding provides public health workers and policymakers with useful policy-relevant evidence in order to maintain and even further improve the gains of increased vaccination coverage achieved during the flu season 2020–2021.

The COVID-19 pandemic has had a prolonged impact on many people working in different sectors. This paper focuses on the psychological stress consequences of professionals working in the educational sector in Andalucía (Spain). Using a sample of 340 educators, this empirical paper identifies the antecedents and profiles of those that ended up with burnout vs. those that were able to develop resilience. Results from OLS regressions show that regardless of the origins of stress, the principal determinant of burnout is clearly a lack of support and a perception of an inability to control a situation. Furthermore, results also show that working sources have a higher impact on the configuration of high burnout, while family sources harm those who are more resilient (low burnout).

Abstract Aflatoxins B1, B2, G1, and G2 were determined at parts-per-trillion levels in beer by immunoaffinity column cleanup and reversed-phase liquid chromatography (LC) with fluorescence detection after trifluoroacetic acid derivatization. Silanized vials were necessary for the evaporation step in order to obtain good recoveries of aflatoxins from spiked beer samples. Recoveries averaged 90–104%, 94%, 84–87%, and 89% for aflatoxins B1, B2, G1, and G2, respectively, at levels of 9.7–133 ng B1, 46 ng B2, 35–140 ng G1 and 41 ng G2/L. Detection limits were 19–20 ng/L for aflatoxins B1 and G1 and 15–16 ng/L for aflatoxins B2 and G2 (signal-to-noise ratio = 3:1) obtained by using an excitation wavelength of 360 nm; at 340 nm these detection limits were lowered to about 2 ng/L. Analysis of 24 beer samples, the majority from the United States and Mexico, showed natural contamination of one sample of Mexican beer at 49 ng B1/L when determined at 360 nm excitation, but reanalysis of 23 of the samples using 340 nm excitation indicated that an additional 4 Mexican samples and one Brazilian sample contained anatoxin B1 at low levels (< 10 ng/L).

Background: The World Health Organization recommends using a face mask to prevent infection with the coronavirus illness 2019 (COVID-19). Students are often nonchalant about maintaining physical or social distance from their peers, undermining the necessity of wearing a face mask both inside and outside of the classroom. The purpose of this study was to determine the students' knowledge, attitudes, and practices about the use of face masks at Novena University in Ogume, Delta State, Nigeria. Methodology: This was a descriptive cross-sectional study carried out among 400 sampled students. A self-administered questionnaire was used to collect the data while descriptive and inferential statistics were used to analyze the data at a significance level set at p<0.05. Results: About 220(55.0%) of the responders were between the ages of 21-25 years, and 260(65.0%) were females. The majority of responders, 340 (85.0%), had a good understanding of how to utilize a face mask. However, both attitudes towards using face masks 280(70.0%) and face mask usage 340(85.0%) were poor. The following demographic characteristics were shown to be substantially linked with knowledge, attitude, and use of face masks: age, sex, marital status, level of study, and religion at p<0.05. Conclusion: The majority of the respondents had an adequate understanding of how to use a face mask, a negative attitude about using a face mask, and poor practice of using a face mask to prevent COVID-19 infection. The study recommends the need for public health enlightenment campaign and education on the value and correct face mask usage among students in tertiary institutions.

3532 Background: Tanespimycin (17-AAG/KOS 953) disrupts Hsp90, a molecular chaperone of MM client proteins including IL-6 and IGF-1R that are key to MM growth, survival and drug resistance. Single agent T was well tolerated with modest anti- MM activity. Preclinical studies suggest potential synergy with BZ. Methods: Pts received BZ as IVB followed by 1-hr infusion of T on D1,4,8,11 q 21d. Results: 49 pts were enrolled in 7 cohorts (T 100- 340 mg/m2; BZ 0.7 - 1.3 mg/m2). PK of T was similar with or without BZ. Inhibition of 20S proteasome with T+BZ was not different vs. historical BZ single agent data. PBLs showed induction of Hsp70 4h post-infusion with maintenance of induction prior to T infusion across the dosing interval; pAKT plus total AKT were also reduced 4 and 72h following infusion. CD138 but not CD4 or CD8 cells from serial BM aspirates showed induction of apoptosis by flow cytometry. In addition, ↓expression of IGR-1R and IL-6R client proteins was seen after treatment. Safety: In Cohort 7, 19 pts received T 340 / BZ 1.3 mg/m2. Common all-grade (G) drug-related toxicity (n=19) included diarrhea (42%), nausea (32%), vomiting (26%), ↑ AST/ALT/Alk Phos (26%/21%/21%), myalgias (16%), and dizziness (16%). G3 thrombocytopenia was noted in 16% with no other G3 toxicity observed in more than 1 pt. DLT was seen in 2 pts: G3 myalgias/cramps and dehydration (reversible in both). G1–2 only treatment-emergent peripheral neuropathy was recorded in 15%. Activity: Responses have been seen across dose levels in BZ-naïve, pre-treated and ref pts (“ref” defined as no response to or disease progression within 60d of last dose of BZ-containing regimen). Specifically, 1 BZ-ref pt with 3 prior regimens had confirmed PR after 2 cycles and continues in Cycle 9 (M-spike ↓92%); a 2nd pt with 2 prior regimens achieved PR after 2 cycles and continues in Cycle 7; a 3rd pt with 7 prior regimens with confirmed PR after 3 cycles continues in Cycle 6. Conclusions: Treatment with T 340/ BZ 1.3 combination had generally manageable toxicity. Durable Hsp90 inhibition and similar proteasome inhibition (vs single-agent BZ) was seen. Importantly, anti-MM activity in BZ-ref pts was observed and further investigation of this combination in rel/ref MM is therefore warranted. No significant financial relationships to disclose.

BACKGROUND As the epidemic of corona virus disease - 19 (COVID – 19) has struck the entire world, schools and colleges had to shut, there was a sudden shift from in-person education to online education which became difficult for the institutions. There was a distinctive rise of e-learning and this method of learning has several amazing features that would be useful for use during this period as this will constitute a new and fantasizing method of learning for the students. METHODS This is a cross-sectional study. The study participants were the students from dental college in Faridabad from 1st year to the final year of under graduate (UG) program. The total number of participants were 340 students. An online questionnaire was designed and given to students through the platform, google forms. This questionnaire consisted of three parameters - attitude, social presence, and student satisfaction. RESULTS Among the 340 students, 40 % of the students were males and 60 % of them were females. The three domains measured attitude, social presence, and satisfaction; to elearning had fourteen, seven and nine questions respectively. Pearson’s correlation test was applied, P - value was significant at P ˂ 0.05. When the three perspectives of e-learning were correlated with e-learners using pearson’s correlation coefficient, it was found that there was a very strong positive correlation among these three domains (P = 0.0001 for all three perspectives).The correlation between the three perspectives of e-learning, attitude versus social presence was 0.773, attitude versus satisfaction was 0.756 and social presence versus satisfaction was 0.794. CONCLUSIONS A predominantly positive response has been observed for satisfaction aspect. The results showed a positive response as it was seen in other surveys. When it comes to the social presence, the study shows that the online setting becomes impersonal but the comfort in collaboration is better than offline model.

Health Care Workers are at the front line of the fight against Covid-19. The aim of this study was to evaluate the acceptability of vaccination against COVID-19 among health professionals (physicians, dentists, pharmacists) two weeks prior to the start of the Greek vaccination campaign against COVID-19. A cross-sectional online survey was conducted over the period 15–22 December 2020 in 340 health professionals in Central Greece. We found a high level of acceptance for COVID-19 vaccine (78.5%) and a high vaccination coverage for the influenza vaccine (74%). Age > 45 years (OR = 2.01; 95% C.I. = 2.01−4.3), absence of fear over vaccine safety (OR = 4.09; 95% C.I. = 1.36–12.3), and information received from the Greek public health authorities (OR = 11.14; 95% C.I. = 5.48–22.6), were factors independently associated with the likelihood of COVID-19 vaccination acceptance. Our study indicates a high level of the COVID-19 vaccination acceptance among physicians, dentists and pharmacists. Nevertheless, several interventions can be implemented to increase acceptance of vaccine among health-care workers (HCWs) and could be especially directed at younger and vaccine-hesitant health care workers due to fear of vaccine side-effects. Last, our results provide some evidence that receiving vaccine-related information from the Greek Center for Diseases Control (E.O.D.Y.) could reduce the drivers of hesitancy and enhance the acceptability of COVID-19 vaccination.

The Covid-19 pandemic has significantly impacted medical education, especially the parallel curriculum, which encompasses several extracurricular activities, such as academic leagues, internships, extension projects, undergraduate research projects, teaching assistance, and elective courses. This study aims at analyzing the result of the Covid-19 pandemic on the parallel curriculum from the perspective of medical students. This is an exploratory-descriptive, cross-sectional study, using an online questionnaire via Google Forms® with Likert-type scale questions. The sample consisted of 340 Medicine students, from the 4th to the 12th terms, from Curitiba, Paraná. The online modality facilitated the submission of scientific papers, as well as the accessibility to medical events, which had the highest adherence among the evaluated activities. Participation in scientific research stands out, especially for students in the basic/ clinical cycle. Therefore, most participants agree that there are adaptations to be maintained in the post-pandemic period.

We conducted a single-center, non-interventional retrospective study of melanoma patients with COVID-19 (1 March 2020 until 17 March 2023). The cohort was further divided into three groups according to the periods of SARS-CoV-2 variant dominance in Greece. We recorded demographics, comorbidities, vaccination data, cancer diagnosis/stage, types of systemic melanoma treatments, date of COVID-19 diagnosis and survival. We identified 121 patients. The vast majority (87.6%) had advanced disease (stages III or IV). A total of 80.1% of the patients were receiving immune checkpoint inhibitor-based therapies, 92.5% had asymptomatic/mild COVID-19 and 7.4% had moderate/severe/critical disease, while 83.5% contracted COVID-19 during the third period of the pandemic. Sixteen patients (13.2%) were hospitalized for COVID-19 with a median length of stay of 12 days (range: 1–55 days). Advanced age, heart failure, number of comorbidities (≤1 vs. >1), vaccination status and the time period of the infection correlated with more severe COVID-19, whereas only heart failure and time period were independently correlated with severity. The 30-day mortality rate after COVID-19 was 4.2%. With a median follow-up of 340 days post-COVID-19, 17.4% of patients were deceased. In this cohort of melanoma patients with COVID-19, the 30-day mortality rate was low. There was no association between melanoma stage, treatment receipt and type of treatment with COVID-19 severity.

Background: Fungemia is associated with high rates of morbidity, mortality, and increase in length of hospital stay. Several studies have recognized increased rates of candidemia since the COVID-19 pandemic. Methods: Patients with candidemia during January through May 2020 were identified through Theradoc. Patient demographics, comorbidities, hospital management, and microbiology were extracted by medical chart review. Patients were divided into cohorts based on COVID-19 status. The Fisher exact and Satterthwaite tests were used for analyses of categorical and continuous variables, respectively. Results: Overall, 31 patients developed candidemia and 12 (38.7%) patients tested SARS-CoV-2 positive. Candida glabrata was the most prevalent causative organism in both groups. On average, COVID-19 patients developed fungemia 12.1 days from admission, compared to 17.8 days in the COVID-19 negative or untested cohort (P = .340). Additionally, COVID-19 patients with a fungemia coinfection were significantly more likely to expire; 10 COVID-19 patients (83.3%) died, compared to 7 (36.8%) in the COVID-19–negative or untested cohort (P = .025). The cohorts did not demonstrate statistically significant differences in terms of demographic, comorbidities, hospital management, or coinfections. Conclusions: The prevalence of fungemia in COVID-19 patients is significantly greater than historically reported figures. Known risk factors for candidemia, such as use of corticosteroid, use of central venous catheters, and prolonged ICU length of stay were higher in the SARS-CoV-2–positive cohort in this period, which likely contributed to increased fungemia rates, as these factors are also more pronounced in those with COVID-19. Patients who developed candidemia in the COVID-19 cohort had poorer outcomes than those who were SARS-CoV-2 negative or were untested. Further investigation should be conducted in larger studies.Funding: NoDisclosures: None

This article aims to share an experience on the process taken by the University of Dar es Salaam to adopt and deliver technology-enhanced teaching and learning during the COVID-19 crisis. The university started by forming a team which conducted an audit to identify existing ICT infrastructure, skills gaps amongst instructors, and information systems that could be quickly adopted to deliver various courses during the COVID-19 crisis. The Moodle system, Zoom video conferencing system, and Postgraduate Information Management System were identified and recommended. After the audit, 340 instructors were trained on identified systems and 369 new courses were developed. Although face-to-face classes resumed a few months after the training and preparations, postgraduate courses continued to be offered via the blended mode with the Zoom and Moodle systems being used. The experience gathered from this study contributes towards knowledge of ICT integration in teaching and learning and can be integrated into teaching during the COVID-19 crisis in resource-constrained universities in sub-Saharan Africa and beyond.

Closures of educational establishments owing to the COVID-19 pandemic have impacted individuals globally. Educational organizations of all levels have been compelled to use online instruction because comprehensive safety precautions have been taken to minimize the spread of disease during the COVID-19 contagion, which has increased technostress. Both public and private organizations utilized these strategies, allowing the individual to work virtually. Purpose- This work examines the association between the perceived technostress attributes and instructors in Cambodian academic institutions during the COVID-19 pandemic. Design/Methodology- It used a quantitative method and constructed a research instrument to examine (340 participants) of public and private instructors service during the outbreak. Additionally, the data was collected and analyzed using structural equation modeling (SEM). Findings- The study revealed that technostress had a substantial effect on the gender, age, and working experience of educators. Hence, given the rapid evolution of ICT trends, it is appropriate to design practical training and wellness programs to alleviate technostress and foster a sense of technological competence and personal relevance.
