Knowledge of the role of hospital conditions in SARS-CoV-2 transmission should inform strategies for the prevention of nosocomial spread of this pathogen and of similarly transmitted viruses. This study aimed to identify risk factors for nosocomial acquisition of SARS-CoV-2. We ran a nested case-control study with incidence density sampling among adult patients hospitalized for >7 days (August-December 2020).

Background In complicated endovascular infections by methicillin-resistant (MRSA) or (MRSE), when first-line therapy with vancomycin (VAN) or daptomycin (DAP) fails, combination therapy with ceftaroline (CFT) and DAP has been shown to be a useful approach as salvage therapy for persistent MRSA bacteremia. Objectives This study aimed to describe experience with daptomycin and ceftaroline combination therapy in MRSE-complicated endovascular infections. Methods A single-center retrospective review of consecutive patients with MRSE-complicated endovascular infections treated with ≥72 hours of DAP+CFT at any time during the course of treatment, from January 1, 2016 to December 31, 2020, at Centro Hospitalar Universitário São João (CHUSJ), Porto, Portugal, was conducted.

Strategic and standardised approaches to analysis and reporting of surveillance data are essential to inform antimicrobial resistance (AMR) mitigation measures, including antibiotic policies. Targeted guidance on linking full-scale AMR and antimicrobial consumption (AMC)/antimicrobial residues (AR) surveillance data from the human, animal, and environmental sectors is currently needed. This paper describes the initiative whereby a multidisciplinary panel of experts (56 from 20 countries-52 high income, 4 upper middle or lower income), representing all three sectors, elaborated proposals for structuring and reporting full-scale AMR and AMC/AR surveillance data across the three sectors.

Third-generation cephalosporins are widely used due to the convenient spectrum of activity, safety, and posology. However, they are associated with the emergence of multidrug-resistant organisms, which makes them important targets for antimicrobial stewardship interventions. We aimed to assess the appropriateness of empirical prescriptions of ceftriaxone in a tertiary hospital.

There is a large reservoir of individuals with past hepatitis B virus (HBV) infection that are in risk for HBV reactivation when immunosuppressed. On the setting of hematologic malignancy, the malignancy itself and currently used treatments, especially anti-CD20 agents, have risk of HBV reactivation. Antiviral prophylaxis is recommended by some international societies.

Objectives: To assess whether electronic records data could improve the efficiency, exhaustiveness, and representativeness of SSI surveillance by selecting a group of high-risk patients for manual review.

Methods: Colorectal surgeries (2016-2018) and cholecystectomies (2017-2018) were selected. Post-surgical antibiotic use, positive culture, C-reactive protein (CRP) values, body temperature, leukocyte count, surgical re-intervention, admission to the emergency room, and hospital readmission were retrieved.

Ceftazidime/avibactam combines ceftazidime with a new beta-lactam that successfully that inhibits Amber Class A and D carbapenemases. We report a clinical case of a 61 year-old man with a carbapenemase-producing intra-abdominal infection after an elective abdominal hernia repair. The infection was successfully managed with multiple abdominal surgeries, drainage and combined antibiotic therapy with ceftazidime/avibactam plus tigecycline.

Rubella is a vaccine preventable infection, and congenital rubella the most feared complication of this disease. Although young adult women are at greatest risk of post-vaccine rubella, this is also the group who potentially benefits the most from vaccine protection. Since post-vaccine disease has a mild and self-limited course, the benefit clearly exceeds the risk.

Article Synopsis
  • The study investigated the global distribution of HIV-1 subtypes, focusing on newly diagnosed patients in western Europe, where subtype B is most prevalent.
  • Conducted as a retrospective analysis from 2006 to 2012, it included 592 patients and compared demographic and epidemiological characteristics between those with subtype B and other subtypes using various statistical methods.
  • Results showed that subtype B was primarily found in younger males and MSM (men who have sex with men), while non-B subtypes were more prevalent in heterosexuals and drug users, with non-B subtypes also showing higher rates of resistance mutations.

Tetralogy of Fallot is the most frequent cyanotic congenital cardiopathy. Its physiopathology has been progressively described which has made better treatment possible. The four characteristic morphologic abnormalities are: interventricular communication, subpulmonary stenosis, biventricular origin of the aortic valve and right ventricular hypertrophy, which are the direct result of the antero-cephalad deviation of the ventricular septal outlet and hypertrophy of the septoparietal trabeculations.
