RESUMO
Since late December 2019, severe acute respiratory syndrome coronavirus 2 has spread across the world, which resulted in the World Health Organization declaring a global pandemic. Coronavirus disease 2019 (COVID-19) presents a highly variable spectrum with regard to the severity of illness. Most infected individuals exhibit a mild to moderate illness (81%); however, 14% have a serious disease and 5% develop severe acute respiratory distress syndrome (ARDS), requiring intensive care support. The mortality rate of COVID-19 continues to rise across the world. Data regarding predictors of mortality in patients with COVID 19 are still scarce but are being actively investigated. The present multicenter retrospective observational study provides a complete description of the demographic and clinical characteristics, comorbidities and laboratory abnormalities in a population of 421 hospitalized patients recruited across eight infectious disease units in Southern Italy (Sicily) with the aim of identifying the baseline characteristics predisposing COVID-19 patients to critical illness or death. In this study, older age, pre-existing comorbidities and certain changes in laboratory markers (such as neutrophilia, lymphocytopenia and increased C-reactive protein levels) at the time of admission were associated with a higher risk of mortality. Male sex, on the other hand, was not significantly associated with increased risk of mortality. Symptoms such as fatigue, older age, a number of co-pathologies and use of continuous positive airway pressure were the most significant contributors in the estimation of clinical prognosis. Further research is required to better characterize the epidemiological features of COVID-19, to understand the related predictors of death and to develop new effective therapeutic strategies.
RESUMO
INTRODUCTION: The Baveno VI consensus guidelines and an expanded algorithm suggest that transient elastography (TE) and platelet (PLT) count can be used to identify patients with cirrhosis who can avoid esophagogastroduodenoscopy (EGD). The primary aims of this study were to assess the ability of a simple algorithm, which uses only laboratory parameters, to predict medium/large esophageal varices (EV) in patients with hepatitis C virus (HCV) and cirrhosis from the Rete Sicilia Selezione Terapia-HCV (RESIST-HCV) cohort and to compare the performance of the algorithm with Baveno VI and Expanded Baveno VI criteria. The secondary aim was to assess the role of TE in ruling out large EV. METHODS: In total, 1,381 patients with HCV-associated cirrhosis who had EGD and TE within 1 year of starting treatment with direct-acting antivirals were evaluated. Using multivariate logistic analysis, laboratory variables were selected to determine which were independently associated with medium/large EV to create the RESIST-HCV criteria. These criteria were tested in a training cohort with patients from a single center (Palermo) and validated with patients from the 21 other centers of the RESIST-HCV program (validation cohort). RESULTS: In the entire cohort, medium/large EV were identified in 5 of 216 patients (2.3%) using the Baveno VI criteria and 13 of 497 patients (2.6%) using the Expanded Baveno VI criteria. PLT count and albumin level were independently associated with medium/large EV. The best cut-off values were a PLT count greater than 120 × 10 cells/µL and serum albumin level greater than 3.6 g/dL; negative predictive values (NPVs) were 97.2% and 94.7%, respectively. In the training cohort of 326 patients, 119 (36.5%) met the RESIST-HCV criteria and the NPV was 99.2%. Among 1,055 patients in the validation cohort, 315 (30%) met the RESIST-HCV criteria and the NPV was 98.1%. Adding TE to the RESIST-HCV criteria reduced the avoided EGDs for approximately 25% of patients and the NPV was 98.2%. DISCUSSION: The "easy-to-use" RESIST-HCV algorithm avoids EGD for high-risk EV screening for more than 30% of patients and has the same performance criteria as TE. Using these criteria simplifies the diagnosis of portal hypertension.

BACKGROUND & AIMS: Studies have produced conflicting results of the incidence of hepatocellular carcinoma (HCC) in patients with hepatitis C virus-associated cirrhosis treated with direct-acting antivirals (DAAs). Data from clinics are needed to accurately assess the occurrence rate of HCC in patients with cirrhosis in the real world. METHODS: We collected data from a large prospective study of 2,249 consecutive patients (mean age = 65.4 years, 56.9% male) with hepatitis C virus-associated cirrhosis (90.5% with Child-Pugh class A and 9.5% with Child-Pugh class B) treated with DAAs from March 2015 through July 2016 at 22 academic and community liver centers in Sicily, Italy. HCC occurrence was evaluated by Kaplan-Meier curves. Cox regression analysis was used to identify variables associated with HCC development. RESULTS: A sustained virologic response (SVR) was achieved by 2,140 patients (total = 95.2%; 95.9% with Child Pugh class A and 88.3% with Child Pugh class B; P < .001). Seventy-eight patients (3.5%) developed HCC during a mean follow-up of 14 months (range = 6-24 months). At 1 year after exposure to DAAs, HCC developed in 2.1% of patients with Child-Pugh class A with an SVR and 6.6% of patients with no SVR and in 7.8% of patients with Child-Pugh class B with an SVR and 12.4% of patients with no SVR (P < .001 by log-rank test). Albumin level below 3.5 g/dL (hazard ratio = 1.77, 95% confidence interval = 1.12-2.82, P = .015), platelet count below 120 × 109/L (hazard ratio = 3.89, 95% confidence interval = 2.11-7.15, P < .001), and absence of an SVR (hazard ratio = 3.40, 95% confidence interval = 1.89-6.12, P < .001) were independently associated increased risk for HCC. The mean interval from exposure to DAAs to an HCC diagnosis was 9.8 months (range = 2-22 months) and did not differ significantly between patients with (n = 64, 9.2 months) and without (n = 14, 12.0 months) an SVR (P = .11). A larger proportion of patients with an SVR had a single HCC lesion (78% vs 50% without an SVR; P = .009) or an HCC lesion smaller than 3 cm (58% vs 28% without an SVR; P = .07). CONCLUSIONS: In an analysis of data from a large prospective study of patients with hepatitis C virus-associated compensated or decompensated cirrhosis, we found that the SVR to DAA treatment decreased the incidence of HCC over a mean follow-up of 14 months.

The relationship between the concentration of plasma progesterone (P4) during embryo attachment or at recognition of pregnancy, and that of pregnancy-associated glycoprotein (PAG) was assessed in dairy cows. The outcome of artificial insemination (AI) was classified as positive (AI+), negative (AI-), or late embryonic mortality (EM) by measuring circulating PAG concentrations and by ultrasonography. Based on P4 concentrations at either day 21 or day 15, AI+ and EM cows were classified into 'low' (P4 concentrations

Fungal sepsis is an important cause of fever resistant to antibiotic therapy that is very often taken into marginal account. It should instead be particularly considered in patients with a long history of immune depression such as diabetes or chronic and debilitating diseases. Blood cultures are essential for diagnostic purposes, preferably performed in antibiotic wash-out, since they may allow identification of pathogenic (or opportunistic) fungi responsible for episodes of fungal sepsis. The case described illustrates an episode of systemic infection by Rhodotorula glutinis correlated with the presence of CVC.
