Full textThe purpose of this study was to investigate the prognostic significance of standard electrocardiogram (ECG) in a large cohort of patients with hypertrophic cardiomyopathy (HCM). In this multicenter study 841 HCM patients (66% men, mean age 48±17 yrs) were followed for 7.1±7.1 years and the first collected ECG was considered for the analysis. The results showed that independent predictors of sudden cardiac death were unexplained syncope (p 0.004), ST segment elevation and/or giant positive T waves (p 0.048), QRS duration >= 120 ms (p 0.017). Two models has been contructed to predict the risk of sudden death: the first based on the already well known established risk factors (wall thickness >= 30 mm, non-sustained ventricular tachycardia on ECG Holter monitoring, syncope and family history of sudden death) and the second with the addition of ST segment elevation/giant positive T waves and QRS duration >= 120 ms. Whereas both models stratified patients according to the number of risk factors, the second model showed a higher predictive power (chi-square from 12 to 22, p 0.002). In conclusion in HCM standard ECG has a prognostic value and improves the current risk stratification model.

Full textBackground/Objectives To investigate the hypothesis that repeated lifting tasks could be a risk factor for retinal detachment. Methods Case-control study (case definition: surgically treated retinal detachment. Cases were identified among patients operated for retinal detachment in two large urban hospital in Bologna and Brescia. Controls were drawn from outpatients attending an eye clinic in the same catchment area. 104 cases and 173 controls (blind to the study hypothesis) responded to a structured questionnaire regarding individual, pathological and work-related factors possibly related to retinal detachment, including past/present occupational lifting tasks. Three lifting categories were defined based on the median “cumulative lifting index” (product of load, manoeuvres/hour and lifting-years) among manual workers: no lifting (reference category); light lifting; heavy lifting. Odds ratios for retinal detachment associated with “heavy”, “moderate” or “light” occupational lifting in an unconditional logistic regression model (adjusted for age and sex) were obtained. Results In addition to ocular surgery and myopia (known risk factors), an independent associations were recorded for heavy lifting (odds ratio 3.6, 95% confidence interval, 1.5 to 9.0). Likelihood ratio tests did not reveal interactions between heavy lifting, ocular/cataract surgery and myopia. Conclusions The results support the plausible hypothesis that heavy occupational lifting (involving Valsalva’s manoeuvre) may be a relevant risk factor for retinal detachment. Moreover these preliminary results confirmed, as reported in literature, an increased risk of retinal detachment for myopic subjects and for those who have undergone cataract surgery. Our observations emphasize the importance of prevention especially in subjects involved in the manual handling of loads, particularly if short-sighted.

Full textDrug-induced liver injury (DILI) is a term that describes abnormalities in liver function tests related to medication intake. Acetaminophen is the most common cause of DILI followed by antibiotics, NSAIDs, and antitubercular medications. NSAIDs represent one of the most widely used classes of drugs. Numerous case reports have described patients who develop fatal liver injury while taking NSAIDs. Several NSAIDs were withdrawn from the market because of hepatic ADRs. The latest warning signal for hepatotoxicity induced by a NSAID is related to nimesulide. In some European countries, Finland, Spain, and Ireland, nimesulide was suspended from the market because of an associated high frequency of hepatotoxicity. In contrast, a recent referral of the EMEA concluded that the benefits of the drug outweigh its risks. However, the full extent of the risk of nimesulide-induced liver injury is still a much debated issue within the EMEA. Primary objectives was to estimate the relative risk of liver injury induced by drugs with a prevalence of use in the Italian population > or = 6% This study is designed as a multicenter case–control study where cases and controls will all be recruited among patients seen in a hospital context in various parts of Italy. Information regarding demographic data, medical history, coexisting illnesses, lifestyles and dietary habits, alcohol, tobacco and coffee intake, use of herbal products, and drug use (including doses taken and indication for use on each day of exposure) will be collected directly from all patients through a structured interview. Preliminary results of this study confirm a significant relative risk (Odds Ratio) of liver injury associated with the use of nimesulide, NSAIDs, some antibiotics like macrolides and paracetamol. The results of this study could strongly affect regulatory decisions within the National Health Service.

Full textObjectives: To assess the role of fetal magnetic resonance imaging (MRI) in detecting associated anomalies in fetuses presenting with mild and moderate isolated ventriculomegaly (VM) undergoing multiplanar ultrasound (US) evaluation of fetal brain. Methods: Multicenter, retrospective, cohort study involving 15 referral fetal medicine centers in Italy, United Kingdom, and Spain. Inclusion criteria: fetuses affected by isolated VM on US, undergoing detailed assessment of fetal brain via a multiplanar approach. Primary outcome: to report the rate of additional CNS anomalies detected exclusively at prenatal MRI and missed at US; secondary aim: to estimate the incidence of additional anomalies detected exclusively after birth and missed at prenatal imaging. Results: 556 fetuses with a prenatal diagnosis of isolated fetal VM on US were included. Additional structural anomalies were detected at prenatal MRI and missed at US in 5.4% (95% CI 3.8-7.6) of cases. Fetuses with an associated anomaly detected only at MRI were more likely to have moderate compared to mild VM (60.0% vs 17.7%, p<0.001), while there was no significant difference between the proportion of cases with bilateral VM between the two groups (p=0.2). The results of the logistic regression analysis showed that maternal body mass index (OR: 0.85, 95% CI 0.7-0.99, p= 0.030), presence of moderate VM (OR: 5.8, 95% CI 2.6-13.4, p<0.001) and gestational age at MRI ≥24 weeks of gestation (OR: 4.1, 95% CI 1.1-15.3, p= 0.038) were independently associated with the probability of detecting associated anomalies at MRI. Associated anomalies were detected exclusively at birth and missed at prenatal imaging in 3.8% of cases. Conclusions: The rate of associated fetal anomalies missed at US and detected only at fetal MRI in fetuses with isolated mild and moderate VM undergoing neurosonography is lower than that previously reported. The large majority of these anomalies are difficult to detect on ultrasound

Full textENGLISH ABSTRACT Background: patients’ satisfaction for nursing care in the healthcare is an aspect that has become increasingly important over the years, not only for the nursing -as it is counted among nursing sensitive outcomes- but also at in economic and political issues. In Pediatrics, the philosophy most embraced in the Western world is Family Centered Care, which envisages the centrality of the child and his or her family unit in the entire care process. Few studies have evaluated the relationships between the experience of family caregivers regarding the care received and the organizational aspects of nursing care. Objectives: To examine the experience of family caregivers in relation to the hospitalization they have lived with their child and evaluate the relationship with the nursing care received and the care setting Methods: Cross-sectional study; multi-level data (administrative, nurses and caregivers) through convenience sampling. Participation has always been preceded by acceptance to participate in the study following the reading of the informed consent. For these analyses a sub-sample comparable with the studies in the literature was extrapolated. Nine hospitals affiliated with the Italian Pediatric Hospitals Association, located in different Italian regions, were involved in the data collection at the caregivers level. The data were collected through a web survey, at the nurse level, and through the Child HCAHPS, specially adapted and validated for the Italian context (S-CVI 0.91; ICC 0.90; Cronbach's Alpha 0.90). The data were analysed at the unit level through descriptive statistical analysis, to describe the sample and the variables of interest with central trend indices, frequencies and percentages; then, a linear regression model has been built to study the relationships between caregivers’ outcomes and the nursing (workload) and setting (pediatric hospital vs general hospital) variables. Data from to the caregivers’ survey, the Top Box approach was applied as indicated in the literature: each item was recoded as an indicator variable of whether respondents selected the most positive response option (eg "Yes, absolutely", “Always, or “rate 9-10”). All analyses were conducted using IBM SPSS statistical software, version 22. Results: Ninety-six units, 1472 nurses and 635 caregivers were involved in the study. The areas in which the highest percentage values were achieved were those relating to pain and communication with doctors and nurses. The lowest values, on were related to safety, preparation for discharge and comfort. Overall, the responses given by caregivers in pediatric hospitals were better than those reported by caregivers in general hospitals. The linear regression model showed that increasing the workload score by one point decreases the hospital's overall rating by 2.12 points; adding the type of hospital to the model, it was found that being in a pediatric hospital increases the hospital's overall rating by 0.28 points. Conclusions: this is the first study conducted in Europe that investigates the experience of caregivers in the Pediatrics through the gold standard tool for evaluating Family Centered Care, and is also the first to relate these outcomes with the characteristics of the nursing staff. These data confirm once again how nursing care can influence the hospitalization experience by impacting on the quality and care provided. In addition, these data can be very useful in identifying improvements to make pediatric nursing care increasingly family-centered and effective.

Full textBackground. Il trattamento ottimale della Sindrome da Antifosfolipidi (APS) ostetrica è attualmente sconosciuto. La terapia con aspirina a basso dosaggio (LDA) da sola o associata all’eparina rappresenta il trattamento convenzionale per l’APS ostetrica. Nonostante questo trattamento, circa il 20% delle gravidanze hanno esito sfavorevole. Recentemente abbiamo individuato alcuni fattori di rischio aggiuntivi di perdita gravidica in corso di gravidanza trattata con terapie convenzionali. Scopo della Tesi. Confrontare gli outcomes di gravidanza ottenuti a seguito dei diversi trattamenti e definire dei precisi profili di rischio al fine di analizzare l’efficacia della terapia sulla base della stratificazione del rischio. Materiali e Metodi. E’ stato condotto uno studio europeo di tipo retrospettivo e multicentrico. Sono stati raccolti i dati basali e quelli in corso di gravidanza di donne affette da APS, diagnosticata sulla base dei Criteri di Sydney, che presentavano almeno uno dei seguenti tre fattori di rischio aggiuntivi: associazione con il Lupus Eritematoso Sistemico (LES), triplice positività per Antifosfolipidi (aPL) e pregressa trombosi. Sono state prese in considerazione le pazienti trattate con le seguenti terapie: LDA, eparina a dose profilattica ± LDA, eparina a dose terapeutica ± LDA, protocolli di II livello (plasmaferesi/immunoassorbimento e/o immunoglobuline endovena) e nessuna terapia. Le determinazioni degli anticardiolipina e anti-Beta2 Glicoproteina I sono state eseguite presso i singoli Centri con il metodo ELISA seguendo procedure diverse sia “home-made” che commerciali, mentre il Lupus Anticoagulant è stato testato con una serie di metodi emocoagulativi in accordo con la corrente letteratura. I metodi statistici utilizzati sono stati l’analisi univariata e la regressione logistica. Risultati. Il numero di gravidanze considerate nello studio è stato complessivamente 202, relative a 158 pazienti. L’età media delle donne al momento della gravidanza era 32,5 anni ± 4,6 DS (range: 20-44) con una durata media di malattia di 5,2 anni ± 4,5 (range: 0-22). L’esito favorevole è stato osservato in 149 gravidanze (73,8%), che si sono concluse con la nascita di 150 neonati (un parto gemellare), di cui 78 (52%) maschi e 72 femmine (48%), nati mediamente alla 36,2^ SG ± 3 DS, con un Apgar medio a 5 minuti di 9,1 ± 1,3 DS e un peso in percentili di 55,8 ± 24,9 DS. Ci sono state 53 perdite (26,2%). In assenza della considerazione del rischio non si sono osservate differenze significative nelle prevalenze dei nati vivi tra le donne che assumevano le diverse tipologie di trattamento prese in considerazione. L’outcome primario è stato analizzato in relazione ai 7 profili di rischio definiti sulla base delle combinazioni di: pregressa trombosi, LES e triplice positività aPL. Accorpando i trattamenti convenzionali, l’unico profilo su cui è stata rilevata una differenza statisticamente significativa è stato quello caratterizzato dai fattori “triplice positività aPL + pregressa trombosi”, dove si è osservata una prevalenza di bambini nati vivi pari al 92,9% nei trattamenti di II livello versus il 58,3% nei trattamenti convenzionali (Fisher test, p-value < 0,05 e OR 9,3; 95% CI:1,3 - 65,6). Questi risultati sono stati confermati dall’analisi di regressione logistica che ha fornito una stima dell’odds ratio aggiustata per le variabili confondenti (OR 9,6; 95% CI: 1,1-84,3). Discussione. Da questo studio è emerso un sottogruppo di donne caratterizzato dalla presenza di “triplice positività aPL + pregressa trombosi”, dove la terapia di II livello è risultata più efficace per numero di nati vivi rispetto al trattamento convenzionale. In particolare si è messa in evidenza l’importanza dell’uso del trattamento di II livello nell’APS ostetrica. Possiamo concludere che la terapia dell’APS ostetrica andrebbe differenziata sulla base del rischio. In particolare, nelle donne con “triplice positività aPL + pregressa trombosi” il trattamento di elezione potrebbe essere quello di II livello associato alla terapia convenzionale.

Full textBackground. The T1-weighted (w)/T2w-ratio has been proposed as a clinically feasible method to investigate white matter (WM) and gray matter (GM) integrity in multiple sclerosis (MS). However, its clinical relevance and suitability in a multicenter setting still need to be fully explored. Objective. To evaluate WM and GM T1w/T2w-ratio in a large multicenter cohort of healthy controls (HC) and MS patients, and its association with clinical disability. Methods. Brain T2w and T1w scans were identified retrospectively at 7 European sites from 434 MS patients (57 clinically isolated syndrome, 196 relapsing-remitting [RR], 106 secondary progressive [SP], 75 primary progressive [PP]) and 270 HC. T1w/T2w-ratio maps were obtained after calibrating signal intensities to eyes and temporal muscle. Sex- and site-adjusted lifespan trajectories of T1w/T2w-ratio were estimated in different brain structures of HC using linear mixed models. Then, sex-, age- and site-specific T1w/T2w-ratio z-scores were derived in MS patients and compared among different clinical phenotypes and levels of disability. The associations with clinical and MRI variables were investigated. Results. In HC, T1w/T2w-ratio increased with age until 50-60 years both in WM and GM. Compared to HC, T1w/T2w-ratio was significantly lower in WM lesions of all MS phenotypes, and in normal-appearing (NA) WM and cortex of RRMS and SPMS patients (p≤0.026), but it was significantly higher in the striatum and pallidum of RRMS, SPMS and PPMS patients (p≤0.042). Furthermore, compared to HC, T1w/T2w-ratio was significantly lower in WM lesions and NAWM in relapse-onset MS patients with mild levels of disability (Expanded Disability Status Scale [EDSS]<3.0) and in the cortex in relapse-onset MS patients with EDSS≥3.0 (p≤0.023). Conversely, T1w/T2w-ratio was significantly higher in the striatum and pallidum in relapse-onset MS patients starting at EDSS≥4.0 (p≤0.005). In PPMS, T1w/T2w-ratio was significantly higher in the striatum and pallidum beyond EDSS≥6.0 (p≤0.001). In MS, longer disease duration, higher EDSS, higher brain T2-hyperintense lesion volume, and lower normalized brain volume were associated with lower T1w/T2w-ratio in WM lesions and cortex and a higher T1w/T2w-ratio in the striatum and pallidum (β from -1.168 to 0.286, p≤0.040). Conclusions. Compared to HC, heterogeneous T1w/T2w-ratio abnormalities were detected in specific brain compartments according to MS clinical phenotypes and disability. Various pathological substrates, including demyelination, inflammation, neurodegeneration, and iron accumulation may explain alterations of this index and their clinical relevance.

Full textFATTORI DI RISCHIO PER IL PRIMO EVENTO TROMBOTICO IN SOGGETTI POSITIVI PER ANTICORPI ANTIFOSFOLIPIDI. STUDIO MULTICENTRICO, PROSPETTICO, DI FOLLOW-UP Introduzione. La sindrome da anticorpi antifosfolipidi (APS) è definita dalla persistente presenza di anticorpi antifosfolpidi (aPL) nel sangue in associazione a manifestazioni trombotiche e/o impegno ostetrico. Alcuni studi hanno recentemente tentato di identificare gli elementi predittivi dell’evento trombotico negli aPL carriers, ma differenze sostanziali nel disegno degli studi, nei criteri di selezione dei pazienti, nei profili anticorpali e nei fattori di rischio considerati rendono difficile trarre delle conclusioni definitive. Obiettivi. Identificare i fattori di rischio per il primo evento trombotico nei pazienti positivi per aPL e valutare l’efficacia della profilassi. Metodi. Lo studio ha incluso pazienti/soggetti provenienti da 11 Centri Reumatologici facenti parte del Gruppo di Studio sulla APS della Società Italiana di Reumatologia. I criteri di inclusione erano i seguenti: età compresa tra 18 e 65 anni, anamnesi negativa per trombosi. I criteri di laboratorio erano: due positività consecutive per aPL, in accordo con i criteri di Sidney, ad almeno 12 settimane di distanza l’una dall’altra. Le donne con l’impegno ostetrico della APS erano incluse. I dati demografici, di laboratorio e clinici erano raccolti all’arruolamento e una volta all’anno durante il follow-up. Il profilo anticorpale era determinato anche al momento dell’evento trombotico. Gli anticorpi anti-cardiolipina e anti-beta2glicoproteina I sono stati determinati da 5 Centri con metodo Elisa “in-house” e dai rimanenti 6 Centri con kits commerciali. Il Lupus Anticoagulant (LA) è stato testato secondo i criteri dell’ International Society of Thrombosis and Haemostasis. Risultati. Duecentocinquantotto pazienti/soggetti (223 donne e 35 uomini di età media 40.9 anni ± 11.1 SD) sono stati reclutati tra l’Ottobre 2004 e l’Ottobre 2008. Il follow-up medio è stato di 35 mesi ± 11.9 SD (range 1-48). Quattordici pazienti (5.4%, annual incidence rate 1.86%) hanno sviluppato il primo evento trombotico (in 9 casi venoso, in 5 arterioso) durante il follow-up. Sette di questi stavano assumendo un trattamento profilattico al momento dell’evento (6 in modo continuativo ed 1 in corso di gravidanza). In 5 casi il primo evento trombotico si è verificato durante un periodo ad alto rischio (gravidanza/puerperio, immobilizzazione o chirurgia). L’ipertensione ed il LA sono stati identificati dall’analisi multivariata come fattori di rischio indipendenti per la trombosi (OR=3.6 con 95% CI= 1.2-11, p<0.05 e OR=3.7 con 95% CI= 1-13.8, p<0.05, rispettivamente). E’ risultato inoltre che la profilassi con aspirina a basso dosaggio (100 mg) e/o eparina durante i periodi ad alto rischio è significativamente protettiva (OR=0.1 con 95% CI= 0.01-0.9, p<0.05), mentre la profilassi data in modo continuativo non è protettiva. Conclusioni. Da questo studio prospettico di follow-up è risultato, in linea con quanto emerso nel nostro precedente studio retrospettivo, che l’ipertensione è un fattore di rischio per il primo evento trombotico in aPL carriers asintomatici. Inoltre anche il LA è risultato un fattore di rischio per trombosi e la profilassi, somministrata nei periodi ad alto rischio, è risultata, infine, protettiva.

Full textPsoriasis is a cutaneous chronic inflammatory disease which can be classified in mild, moderate or severe, according with the skin involvement. For the severe forms, biological therapies have been recently introduced. These therapies often cause a complete clearance of the skin lesions, but they have specific and rigid dose administration regimens. Recently, some studies have proposed a dose tapering to improve the patient's quality of life and reduce the health costs. We considered in this study 199 patients treated with one biological therapy among infliximab, etanercept, adalimumab or ustekinumab, from January 2005 through June 2018. Of them, 96 reached a complete clearance of the lesions (PASI100) maintained for at least 12 months. In this group, we elongated the administration period of the used biologic and we administered a questionnaire about the “healing sensation”. In the other 103 patients, who did not reach the PASI100, we maintained the therapy at the standard dose. We also evaluated the percentage of relapses among the two groups and the association between the incidence of relapses and hypertension, diabetes, psoriatic arthritis or smoking habits. The difference in terms of relapses between the two groups appeared negligible (p-value 0.445) while hypertension has been related to a higher percentage of psoriasis recurrence in both groups. In the group of dose tapering, most patients (61,70%) reported high satisfaction and “healing sensation” after the dose tapering of the biologic. Biological therapies cause often a good therapeutic response or, in most cases, a complete remission of the disease. Our study demonstrated that a dose tapering of biologics maintain good results in terms of efficacy and it is well accepted by the psoriatic patients. More studies are needed to evaluate the long-term efficacy of these new therapeutic regimens of biologics and to study the newly introduced parameter of “healing sensation”.

Full textIn view of fostering transferability of pre-clinical data on the efficacy of remote ischemic conditioning (RIC) in acute ischemic stroke, we designed two multi-centre translational trials in mice and rats of both sexes. We defined to model ischaemic stroke by the transient occlusion of the middle cerebral artery (tMCAo). The improvement of sensorimotor deficits at 48h after tMCAo in RIC-treated animals was defined as the primary outcome. This work presents the harmonization phase relative to the evaluation of sensorimotor deficits by De Simoni neuroscore. Each centre performed different tMCAo durations - 30, 45, 60 min - allowing sufficient variability in the outcome. Animals were monitored post-surgery according to the ARRIVE and IMPROVE guidelines and data was registered into an electronic case report form on RedCap. All animals were video recorded during the neuroscore and the videos (n=11 per species) were distributed and evaluated blindly by raters at all centres. The interrater agreement of neuroscore was described using intraclass correlation coefficient (ICC), ranging between ICC=0 (equivalent to chance) and ICC=1 (perfect agreement), setting a target of ICC≥0.60 as satisfactory. We obtained moderate agreement for mice (ICC=0.50 [0.22-0.77]) and rats (ICC=0.49 [0.21-0.77]). Errors were identified in animal handling and test execution. We thus performed a second training followed by a new blind evaluation replacing the videos with poor experimental execution. The interrater agreement improved for mice (ICC=0.64 [0.37-0.85]) and rats (ICC=0.69 [0.44-0.88]). In conclusion, two dedicated training on the neuroscore allowed us to reach the agreement target for both species and thus next proceed with the interventional phase of the project.

Full textIntroduction: Congenital heart diseases (CHD) are the most frequent congenital anomalies at birth, with an incidence of 1 in 100 live births. The placenta is the most complex fetal organ, responsible of fetal development and growth during pregnancy. Although the development of the placenta and heart occurs in parallel, the relationship between these two organs is unknown and only recently elucidated. Methods: We conducted a retrospective observational study, including patients born exclusively at the G. Gaslini hospital, between January 2014 and March 2018 with a prenatal diagnosis of CHD and an anatomopathological analysis of the placenta, for a total of 151 patients. Fetuses with CHD Mayor were divided into 5 categories, based on cardiovascular physiology, as follows: (1) single ventricle with aortic obstruction, (2) single ventricle with pulmonary obstruction, (3) two hemodynamically unstable ventricles, (4) transposition of the great arteries, (5) two hemodynamically stable ventricles. For each patient, the following data were considered: absolute placental weight, macroscopic and vascular alterations of the umbilical cord, maternal body mass index (BMI), gender, fetal and neonatal intrauterine growth restriction (IUGR), extracardiac anomalies, surgical procedure or percutaneous in the neonatal period. For statistical analysis, the Fisher test was used, with which we studied the dependency ratio between a specific variable and the CHD; a p <0.05 was considered significant. Results: Only four variables showed scientific significance: neonatal surgery (p = 0.000008), associated extracardiac anomalies (p = 0.012), umbilical cord edema (p = 0.007) and gender (p = 0.015). Although we had found a high incidence of abnormal insertion of the umbilical cord in the placentas of heart disease infants, the result of Fisher's analysis showed no dependence between the CHD groups and this variable (p = 0.379). Conclusion: From the analysis of our results, we do not believe that the weight of the placenta can predict the diagnosis of CHD, as previously reported in the literature. Based on our experience, we cannot consider abnormal cord insertion as a high risk factor for CHD. Therefore, we do not consider it necessary to expand the ultrasound screening method by analyzing the cord insertion method. Conversely, the presence of edema of the umbilical cord was found to be CHD dependent therefore, it could be considered a risk factor for CHD. Similarly, gender was also dependent on CHD, with a strong association between the male sex and CHD Mayor. For the future, we believe it is necessary to implement the study with the inclusion of a control group and with the inclusion of other clinical and instrumental variables of the fetus and placenta.

Full textSeveral clinical studies have evaluated the efficacy and tolerability of treatment with immune checkpoint inhibitors in patients with advanced stage non-small cell lung cancer. However, there are still many uncertainties regarding the selection of the patients who could benefit the most from this treatment. In a context in which there is a slow but constant improvement in the prognosis of a disease traditionally considered poor in the short term, the weight of those variables, above all "clinical" ones, linked to the patient and his non-oncological anamnesis, can contribute to predicting the benefit of treatments as well as their potential toxic effects. The present study aims to evaluate in an unselected population the prognostic and predictive weight of different humoral variables (histology and PD-L1 value on tumour biopsy, presence of anemia, LDH value, neutrophil/lymphocyte ratio) and clinical ones (performance status, age, smoking status, type of anemia corrections, disease sites, comorbid burden) in patients with advanced NSCLC candidates to receive immunotherapy according to AIFA indications. A total of 166 patients from two University Hospitals of Pavia were enrolled. The median age of the entire population was 68.5 years. 71% of the patients were male and 29% female. 92% were active smokers or former smokers. About half of the patients (45-18%) had an ECOG PS score of 0, while 43.37% had an ECOG PS score of 1 and 11.45% of 2-3. 25.3% of patients had squamous NSCLC, while 74.7% had non-squamous carcinoma, histotype adenocarcinoma. 27.16% of patients had an immunohistochemical expression of PD-L1 on tumour biopsy <1%, 45.68% between 1 and 49%, 44% ≥ 50%. At the start of immunotherapy treatment, most of the patients (76.51%) presented with stage IV disease. Nivolumab was administered to 50% of patients, pembrolizumab to 34%, atezolizumab to less than 4% and durvalumab to 12% of patients. In most cases, patients received immunotherapy treatment in the 2nd (57.23%) or 3rd (13.86%) line of treatment. About 50% of patients had anemia at the start of treatment and in most cases the cause of the anemia was the underlying chronic disease. Concerning the sites of disease of interest, about 12% of patients had brain metastases, 11% liver disease, 23% skeletal metastasis, 87% lymph node metastasis and 9% pleural metastasis. The results of this study show that immunotherapy is confirmed to be an effective and well tolerated treatment in an unselected population of patients with advanced non-small cell lung cancer. Our study suggests that some clinical variables are particularly influencing the probability of response to treatment as well as the risk of progression at 6 months and the risk of death at 6 and 12 months. These variables are represented by the patient's performance status, the immunohistochemical expression value of PDL 1 on the tumour piece, the presence of anemia before starting treatment and the LDH values and the neutrophil/lymphocyte ratio. In an era in which research is focusing on prognostic or predictive tumour molecular alterations as well as tumour mutational burden, this study highlights how the clinical characteristics of the patient are still an influential basis for predicting the response and the prognosis to oncological treatments, even more with immune checkpoint inhibitors, in which patient's immune system must guide the response to the treatment itself.

Full textIntroduction: Sacubitril/valsartan in heart failure (HF) with reduced ejection fraction (HFrEF) was shown to be superior to enalapril in reducing the risk of death and hospitalization for HF. The aim of this study was to evaluate cardiopulmonary effects of sacubitril/valsartan in patients with HFrEF and the possible correlation with the degree of myocardial fibrosis assessed with cardiac magnetic resonance (CMR). Methods: An observational, prospective study was conducted. 134 outpatients with HFrEF underwent serial cardiorespiratory tests after initiation of therapy with Sacubitril / Valsartan. Of these, 54 patients underwent CMR. The remaining 80 patients did not perform CMR as they had undergone ICD implantation prior to enrollment in the aforementioned study. Results: After a mean follow-up of 13.3 ± 6.6 months, a reduction in systolic blood pressure (p <0.0001), an improvement in FE (p = 0.0003), a reduction in the E/A ratio (p = 0.007), inferior vena cava size (p = 0.009) and NT-proBNP levels (p = 0.007) was observed. During the follow-up, we observed an increase in peak VO2 of 16% (Δ = + 5 mL / Kg / min; p <0.0001) and in O2 pulse of 13% (Δ = +1, 7 mL / beat; p 0.0002), as well as an improvement in ventilatory response associated with a 7% reduction in the VE/VCO2 slope (Δ = 2.5; p = 0.0009). VO2 at the anaerobic threshold (AT-VO2) went from 11.5 +2.6 to 12.5 +3.3 mL / kg / min (p = 0.021); furthermore, an 8% increase in the Δ VO2 / Δ Work ratio (Δ = +0.8 mL / beat; p 0.0001) and an 18% increase in the tolerance to physical exercise (Δ = +16 Watt; p <0.0001). In multivariate logistic regression analysis, the main predictors of events during follow-up were the VE/VCO2> 34 [OR: 3.98 (95% CI: 1.59 10.54); p-value = 0.0028]; the presence of ventilatory oscillation [OR: 4.65 (95% CI: 1.55 1 6.13); p value = 0.0052] and the hemoglobin value [OR: 0.35 (95% CI: 0.21 0.55); p value <0.0001]. In the subgroup of patients undergoing CMR, a lower response after sacubitril/valsartan therapy was observed in the presence of Delayed Enhancement (DE) > 4.6% in terms of improvement in peak VO2 delta (+2.1 vs. + 4.7), pulse of O2 (+1.4 vs. +4.2), FE (+4.1 vs. + 10) and NT-proBNP (760 vs. 810). No significant differences were observed in terms of ΔVO2/ΔWork and VE / VCO2. Conclusions: The results of the study show that therapy with Sacubitril/valsartan improves exercise tolerance, left ventricular ejection fraction, peak VO2 and anaerobic threshold and ventilatory efficiency. The presence of myocardial fibrosis conditions the response to therapy with sacubitril/valsartan. In fact, in these patients, the effects of the drug on the functional capacity and cardiorespiratory parameters, even if maintained, are reduced. However, further studies are needed in order to better understand the mechanism of action of the drug and the effects on cardiac remodelling.

Full textIntroduzione. Nonostante sia un'applicazione clinica da quasi trent'anni, i dati relativi allo stato di salute a lungo termine dei pazienti trapiantati di fegato sono scarsi. Il numero dei pazienti che raggiungono la soglia di sopravvivenza a 10 anni è in aumento, esponendo questa popolazione al rischi associati all'uso cronico degli immunosoppressori. Metodi. Il Centro Trapianti di Fegato di Padova ha coordinato due studi multicentrici spontanei: uno studio retrospettivo, osservazionale, longitudinale, multicentrico (12 Centri Trapianto di Fegato italiani) che valuta la sopravvivenza a lungo termine e le principali caratteristiche della popolazione ricevente; e EPOCAL uno studio spontaneo di Fase II, interventistico, multicentrico (7 Centri Trapianto di Fegato italiani), in aperto, randomizzato, controllato che valuta il rigetto e la perdita del graft a 3 mesi dal trapianto, la funzione renale e l'incidenza degli eventi avversi. Risultati. I dati su 3008 trapianti di fegato effettuati in Italia dal 1993 al 1999 sono stati registrati in un eCRF. I dati di 2846 pazienti con un sufficiente follow-up sono stati usati per le analisi successive. La sopravvivenza a 20 anni dal trapianto è stata stimata al 51%. Un totale di 139 pazienti è stato arruolato nello studio EPOCAL, 92 nel gruppo di studio e 47 nel gruppo di controllo. Non abbiamo trovato differenze significative tra i due gruppi prima all'arruolamento. L'end-point primario dello studio è stato raggiunto: i rigetti acuti confermati da biopsia erano meno del 25 % (sotto 14 %) (p < 0,05). La funzione renale a tre mesi era significativamente migliore nel gruppo di studio (p < 0,05). Conclusioni. Questi studi presentano un profilo di sopravvivenza eccellente della coorte di pazienti italiani trapiantati di fegato da lungo tempo. Mostriamo sicurezza ed efficacia di un protocollo immunosoppressivo con minimizzazione degli inibitori della calcineurina (tacrolimus), e l'introduzione precoce di everolimus. L'insieme dei risultati mostra una strada verso la sopravvivenza a lungo termine dei pazienti con protocolli immunosoppressivi sostenibili.
