The plaque reducing efficacy of oil pulling with sesame oil: a randomized-controlled clinical study.

Objectives: To compare the plaque reducing efficacy of oil pulling with sesame oil compared to distilled water in a randomized, controlled, examiner-blinded parallel group study.

Materials And Methods: Forty probands without advanced periodontal disease of the University Hospital for Restorative Dentistry and Periodontology, Medical University of Innsbruck (Austria) were randomized allocated to test- (sesame oil) or control group (distilled water) and asked to pull daily in the morning for eight weeks with their allotted fluid for 15 min. Rustogi Modified Navy Plaque Index (RMNPI) and gingival bleeding index were assessed at baseline and after four and eight weeks.

Expansion of the MutS gene family in plants.

The widely distributed MutS gene family functions in recombination, DNA repair, and protein translation. Multiple evolutionary processes have expanded this gene family in plants relative to other eukaryotes. Here, we investigate the origins and functions of these plant-specific genes.

Burden of post-acute COVID-19 sequelae in healthcare workers and its course over a 30-month period-results from a prospective multicentre cohort.

Purpose: As healthcare workers (HCW) have been disproportionally affected by COVID-19, its post-acute sequelae (PASC) in HCW can impact healthcare systems. We assessed the burden and course of PASC in HCW over a 30-month period.

Methods: In a prospective multicentre HCW cohort in Switzerland, PASC surveys were conducted in 03/2021, 09/2021, 06/2022, 04/2023, and 10/2023.

Colonization with resistant bacteria in hospital employees: an epidemiological surveillance and typing study.

The objective of this study was to determine the prevalence, molecular epidemiology, and risk factors for gut colonization with extended-spectrum β-lactamase-producing Enterobacterales (ESBL-E), carbapenemase-producing Enterobacterales (CPE), and vancomycin-resistant enterococci (VRE) in healthcare workers (HCWs). In September/October 2022, we performed a cross-sectional study among HCW from 14 institutions in Northeastern Switzerland. HCWs reported risk factors for antimicrobial resistance (covering the last 12-24 months) and provided rectal swabs.
