Using BCG Vaccine to Enhance Nonspecific Protection of Health Care Workers During the COVID-19 Pandemic: A Randomized Controlled Trial.

Background: The BCG (Bacillus Calmette-Guérin) vaccine can induce nonspecific protection against unrelated infections. We aimed to test the effect of BCG on absenteeism and health of Danish health care workers (HCWs) during the coronavirus disease 2019 (COVID-19) pandemic.

Methods: A single-blinded randomized controlled trial included 1221 HCWs from 9 Danish hospitals.

An autologous blood-derived patch as a hemostatic agent: evidence from thromboelastography experiments and a porcine liver punch biopsy model.

Perioperative bleeding is a common complication in surgeries that increases morbidity, risk of mortality, and leads to increased socioeconomic costs. In this study we investigated a blood-derived autologous combined leukocyte, platelet, and fibrin patch as a new means of activating coagulation and maintaining hemostasis in a surgical setting. We evaluated the effects of an extract derived from the patch on the clotting of human blood in vitro, using thromboelastography (TEG).

Using BCG vaccine to enhance non-specific protection of health care workers during the COVID-19 pandemic: A structured summary of a study protocol for a randomised controlled trial in Denmark.

Objectives: The Bacille Calmette-Guérin (BCG) vaccine against tuberculosis is associated with non- specific protective effects against other infections, and significant reductions in all-cause morbidity and mortality have been reported. We aim to test whether BCG vaccination may reduce susceptibility to and/or the severity of COVID-19 and other infectious diseases in health care workers (HCW) and thus prevent work absenteeism.The primary objective is to reduce absenteeism due to illness among HCW during the COVID-19 pandemic.

Risk of adhesive bowel obstruction after abdominal surgery. A national cohort study of 665,423 Danish women.

Background: Adhesive bowel obstruction is associated with considerable morbidity and mortality, but the magnitude of the risk is debated.

Method: In a national cohort of all Danish women with an abdominal operation (N = 665,423) between 1977 and 2013, the risk of adhesive bowel obstruction was assessed by Cox multiple regression. Covariates were the number of abdominal operations, the surgical methods, the anatomical site involved, and the calendar year.

Postpartum urinary tract infection by mode of delivery: a Danish nationwide cohort study.

Objectives: To examine the association between postpartum urinary tract infection and intended mode of delivery as well as actual mode of delivery.

Design: Retrospective cohort study.

Setting And Participants: All live births in Denmark between 2004 and 2010 (n=450 856).

Description of women's personality traits and psychological vulnerability prior to choosing hormone replacement therapy.

Introduction: Data suggest that women using hormone replacement therapy (HRT) represent a special subgroup of the general population regarding, for instance, cardiovascular risk factors and education.

Objective: To analyse if women who choose HRT are characterised a priori by high neuroticism score or by psychological vulnerability.

Design: A prospective population-based study was initiated in 1976 with follow-ups in 1981, 1987 and 1996.
