A survey among physicians in surgery and anesthesiology departments after the first surge of SARS-CoV-2 infections in Germany : Preparing for further challenges ahead.

Background: The SARS-CoV‑2 pandemic has extensively challenged healthcare systems all over the world. Many elective operations were postponed or cancelled, changing priorities and workflows in surgery departments.

Aims: The primary aim of this cross-sectional study was to assess the workload and psychosocial burden of surgeons and anesthesiologists, working in German hospitals during the first wave of SARS-CoV‑2 infections in 2020.

Hydration of Cement in the Presence of Biocidal Modifiers Based on Metal Hydrosilicates.

This article presents the results of a study of the characteristics of hydration and properties of a composite biocidal cement binder containing hydrosilicates of barium, copper or zinc. It was found that copper hydrosilicates block hydration processes, and when zinc hydrosilicates are used, the rate of hydration is determined by the content of silicic acid. The limiting concentrations of biocidal modifiers have been established: zinc hydrosilicates-no more than 4% and copper hydrosilicates-no more than 0.

Reasons for Reduced Moisture Resistance of Sulfur-Extended Asphalt Concrete.

The paper presents the results of a study of the mechanism for reducing the moisture resistance of sulfur-extended asphalt concrete. It is shown that a decrease in moisture resistance occurs due to the occurrence of chemical and physical processes. At the same time, it was found that during the manufacture of sulfur-bitumen composites, toxic gases HS and SO are formed, which are capable of interacting with a mineral filler, as well as the interaction of sulfur with a mineral powder with the formation of sulfur-containing water-soluble salts, the extraction of which leads to a decrease in the moisture resistance of sulfur-bitumen materials.

SARS-CoV-2 in Solid Organ Transplant Recipients: A Structured Review of 2020.

Background: The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic is challenging health systems all over the world. Particularly high-risk groups show considerable mortality rates after infection. In 2020, a huge number of case reports, case series, and consecutively various systematic reviews have been published reporting on morbidity and mortality risk connected with SARS-CoV-2 in solid organ transplant (SOT) recipients.

[Multimodular Cognitive Training for Nursing Staff Aged 50+: Initial Results of a Pilot Study on Feasibility and Efficacy].

The Aim Of The Study: was the assessment of the feasibility of a cognitive training program for employees of care 50+.

Method: A cognitive training program (13 h, 5 sessions) was conducted with 15 nurses of the University Hospital Munich (KUM). Acceptance of and effects on cognitive and psychological performance were determined.

Antigenotoxic effect of kefir and ayran supernatants on fecal water-induced DNA damage in human colon cells.

Fermented dairy products and their component bacteria have been shown to possess health-promoting functions in consumers and recently have been suggested to reduce the risk of colorectal cancer. Kefir and ayran are two popular fermented milk drinks that have their origins in the Caucasus region of Russia. The present study aimed to evaluate their potential anticancer properties in colon cells in vitro.
