Objective: To determine whether povidone iodine in alcohol is noninferior to chlorhexidine gluconate in alcohol to prevent SSIs after cardiac or abdominal surgery.

SARS-CoV-2 Vaccination is Not Associated With Involuntary Childlessness in Female Healthcare Workers: A Multicenter Cohort Study.

Background: There is debate about the causes of the recent birth rate decline in high-income countries worldwide. During the pandemic, concern about the effects on reproductive health has caused vaccine hesitancy. We investigated the association of SARS-CoV-2 vaccination and infection with involuntary childlessness.

SARS-CoV-2 immunity and reasons for non-vaccination among healthcare workers from eastern and northern Switzerland: results from a nested multicentre cross-sectional study.

Aims Of The Study: We aimed to assess the extent of SARS-CoV-2 humoral immunity elicited by previous infections and/or vaccination among healthcare workers, and to identify reasons why healthcare workers decided against vaccination.

Methods: This nested cross-sectional study included volunteer healthcare workers from 14 healthcare institutions in German-speaking Switzerland. In January 2021, SARS-CoV-2 vaccines were available for healthcare workers.

Hepatitis C prevalence and cascade of care among patients in the decentralised opioid agonist therapy programme of the canton of St Gallen, Switzerland: a cross-sectional study.

Background: To eliminate chronic hepatitis C virus (HCV) infection by 2030, 90% of those infected must be diagnosed and 80% treated. In Switzerland, >40% of the estimated 32,000 infected people are still undiagnosed. In the canton of St Gallen, HCV prevalence and cascade of care have only been studied in the centralised opioid agonist therapy (OAT) setting (institutions), although about 80% of OAT patients are treated decentrally (general practitioner [GP] or pharmacy).

Impact of COVID-19 disease on the male factor in reproductive medicine - how-to advise couples undergoing IVF/ICSI.

Context: The COVID-19 pandemic has caused widespread concern about its potential impact on various aspects of human health.

Aims: This narrative review aims to summarise the current knowledge about the impact of COVID-19 on sperm quality and its effect on assisted reproductive technology.

Methods: In this narrative review, a literature search using the PubMed and MEDLINE databases was conducted to identify relevant original research articles published up to 29 January 2023.

Healthcare‑associated infections in intensive care unit patients with and without COVID-19: a single center prospective surveillance study.

Background: The coronavirus disease 2019 (COVID-19) pandemic led to a global increase in healthcare-associated infections (HAI) among intensive care unit (ICU) patients. Whether this increase is directly attributable to COVID-19 or whether the pandemic indirectly (via staff shortages or breaches in infection prevention measures) led to this increase, remains unclear. The objectives of this study were to assess HAI incidence and to identify independent risk factors for HAI in COVID-19 and non-COVID-19 ICU patients.

Effective infection prevention and control measures in long-term care facilities in non-outbreak and outbreak settings: a systematic literature review.

Background: Healthcare-associated infections in long-term care are associated with substantial morbidity and mortality. While infection prevention and control (IPC) guidelines are well-defined in the acute care setting, evidence of effectiveness for long-term care facilities (LTCF) is missing. We therefore performed a systematic literature review to examine the effect of IPC measures in the long-term care setting.

Epidemiology of patients harboring carbapenemase-producing bacteria and comparison with patients with detection of extended-spectrum beta-lactamase-producing Enterobacterales-A retrospective cohort study.

Objective: We evaluated the epidemiology of carbapenemase-producing bacteria (CPB) in Switzerland by comparing risk factors between patients colonized with CPB and patients colonized with extended-spectrum β-lactamase-producing Enterobacterales (ESBL-PE).

Methods: This retrospective cohort study was conducted at the University Hospital Basel in Switzerland. Hospitalized patients with CPB in any sample between January 2008 and July 2019 were included.

Clinical symptoms of SARS-CoV-2 breakthrough infection during the Omicron period in relation to baseline immune status and booster vaccination-A prospective multicentre cohort of health professionals (SURPRISE study).

The effects of different types of pre-existing immunity on the frequency of clinical symptoms caused by the SARS-CoV-2 breakthrough infection were prospectively assessed in healthcare workers during the Omicron period. Among 518 participants, hybrid immunity was associated with symptom reduction for dizziness, muscle or limb pain and headache as compared to vaccination only. Moreover, the frequencies of dizziness, cough and muscle or limb pain were lower in participants who had received a booster vaccine dose.

An intensive care unit outbreak with multi-drug-resistant Pseudomonas aeruginosa - spotlight on sinks.

Background: Pseudomonas aeruginosa and other Gram-negative bacteria have the ability to persist in moist environments in healthcare settings, but their spread from these areas can result in outbreaks of healthcare-associated infections.
