Molecular characterization of Enterobacteriaceae resistant to carbapenem antimicrobials Caracterização molecular de enterobactérias resistentes aos carbapenêmicos

The present study aimed to genotypically and phenotypically characterize clinical isolates of carbapenem-resistant Enterobacteriaceae collected from inpatients at the University Hospital of Santa Maria, during seven months. Among the clinical isolates subjected to the modified Hodge test (MHT), 62.5% were positive, indicating possible production of carbapenemase. Polymerase chain reaction (PCR) demonstrated that bla KPC was the most frequently found gene (31%), followed by bla IMP (12.5%). Combined use of the methods is needed to identify carbapenem resistance in enterobacteria to prevent their spread and control the infections caused by these organisms

Ombitasvir, paritaprevir, and ritonavir, with or without dasabuvir, plus ribavirin for patients with hepatitis C virus genotype 1 or 4 infection with cirrhosis (ABACUS): a prospective observational study

Background We ran a compassionate use nationwide programme (ABACUS) to provide access to ombitasvir, paritaprevir, and ritonavir, with dasabuvir, plus ribavirin for hepatitis C virus (HCV) genotype 1 infection and ombitasvir, paritaprevir, and ritonavir, plus ribavirin for HCV genotype 4 infection in patients with cirrhosis at high risk of decompensation while approval of these regimens was pending in Italy. Methods In this prospective observational study, we collected data from a compassionate use nationwide programme from March 17, 2014, to May 28, 2015. Patients with HCV genotype 1 infection and cirrhosis at high risk of decompensation were given coformulated ombitasvir (25 mg), paritaprevir (150 mg), and ritonavir (100 mg) once daily and dasabuvir (250 mg) twice daily for 12 weeks (patients with HCV genotype 1b infection) or 24 weeks (patients with HCV genotype 1a infection). Patients with HCV genotype 4 infection were given coformulated ombitasvir (25 mg), paritaprevir (150 mg), and ritonavir (100 mg) once per day for 24 weeks. All patients were given weight-based ribavirin. The primary efficacy endpoint was sustained virological response at week 12 after the end of treatment (SVR12), analysed by intention-to-treat. Univariate and multivariate logistic regression analyses were used to identify baseline characteristics associated with SVR12. Adverse events were recorded throughout the study. Findings 728 (96%) of 762 patients with cirrhosis who were given ombitasvir, paritaprevir, and ritonavir, with or without dasabuvir, plus ribavirin therapy for 12 or 24 weeks achieved SVR12. Logistic regression analyses identified that bilirubin concentrations of less than 2 mg/dL were associated with SVR12 (odds ratio [OR] 4·76 [95% CI 1·83–12·3]; p=0·001). 166 (23%) of 734 patients included in safety analyses had an adverse event. 25 (3%) patients discontinued treatment because of adverse events. Asthenia was the most commonly reported adverse event, occurring in 36 (5%) patients. Interpretation Our findings suggest that the safety and effectiveness of ombitasvir, paritaprevir, and ritonavir, with or without dasabuvir, plus ribavirin in patients with HCV genotype 1 or 4 infection and cirrhosis at high risk of decompensation in a real-life setting are similar to those reported in clinical trials. The concordance with clinical trials provides reassurance that the reported efficacy of this treatment in clinical trials will translate to its use in routine clinical practice.

ISARIC-COVID-19 dataset: A Prospective, Standardized, Global Dataset of Patients Hospitalized with COVID-19

The International Severe Acute Respiratory and Emerging Infection Consortium (ISARIC) COVID-19 dataset is one of the largest international databases of prospectively collected clinical data on people hospitalized with COVID-19. This dataset was compiled during the COVID-19 pandemic by a network of hospitals that collect data using the ISARIC-World Health Organization Clinical Characterization Protocol and data tools. The database includes data from more than 705,000 patients, collected in more than 60 countries and 1,500 centres worldwide. Patient data are available from acute hospital admissions with COVID-19 and outpatient follow-ups. The data include signs and symptoms, pre-existing comorbidities, vital signs, chronic and acute treatments, complications, dates of hospitalization and discharge, mortality, viral strains, vaccination status, and other data. Here, we present the dataset characteristics, explain its architecture and how to gain access, and provide tools to facilitate its use
