How do professional relationships influence surgical antibiotic prophylaxis decision making? A qualitative study.

Background: Surgical antibiotic prophylaxis (SAP) is a critical area to optimize to reduce the escalation of antimicrobial resistance. This article explores the ways by which interpersonal relationships influence SAP decision making.

Methods: Twenty surgeons and anesthetists participated in in-depth semistructured interviews on SAP prescribing.

Clinical and social barriers to antimicrobial stewardship in pulmonary medicine: A qualitative study.

Background: The treatment of pulmonary infections is one of the largest indications for antibiotics in human health care, offering significant potential for antibiotic optimization internationally. This study explores the perspectives of pulmonary clinicians on antibiotic use in hospital pulmonary infections.

Methods: Twenty-eight pulmonary doctors and nurses from 2 hospitals participated in semi-structured interviews focusing on their experiences of antibiotic use.

A randomised controlled trial of Heparin versus EthAnol Lock THerapY for the prevention of Catheter Associated infecTion in Haemodialysis patients--the HEALTHY-CATH trial.

Background: Tunnelled central venous dialysis catheter use is significantly limited by the occurrence of catheter-related infections. This randomised controlled trial assessed the efficacy of a 48 hour 70% ethanol lock vs heparin locks in prolonging the time to the first episode of catheter related blood stream infection (CRBSI).

Methods: Patients undergoing haemodialysis (HD) via a tunnelled catheter were randomised 1:1 to once per week ethanol locks (with two heparin locks between other dialysis sessions) vs thrice per week heparin locks.

Antigen-specific CD4 cells assist CD8 T-effector cells in eliminating keratinocytes.

Keratinocytes expressing tumor or viral antigens can be eliminated by antigen-primed CD8 cytotoxic T cells. CD4 T-helper cells help induction of CD8 cytotoxic T cells from naive precursors and generation of CD8 T-cell memory. In this study, we show, unexpectedly, that CD4 cells are also required to assist primed CD8 effector T cells in rejection of skin expressing human growth hormone, a neo-self-antigen, in keratinocytes.

Rationale and design of the HEALTHY-CATH trial: a randomised controlled trial of Heparin versus EthAnol Lock THerapY for the prevention of Catheter Associated infecTion in Haemodialysis patients.

Background: Catheter-related bacteraemias (CRBs) contribute significantly to morbidity, mortality and health care costs in dialysis populations. Despite international guidelines recommending avoidance of catheters for haemodialysis access, hospital admissions for CRBs have doubled in the last decade. The primary aim of the study is to determine whether weekly instillation of 70% ethanol prevents CRBs compared with standard heparin saline.
