Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), causing the coronavirus disease 2019 (COVID-19) pandemic, leads to illness and death. Various risk factors for a severe course, such as higher age, male gender and pre-existing illnesses are known. However, pathophysiological risk factors are largely unclear. Notably, the mild course of disease in children is conspicuous. Angiotensin converting enzyme 2 (ACE2) serves as a receptor for SARS-CoV-2 and is a key enzyme in infection. Differences in the distribution of ACE2 can provide insights into different courses of COVID-19. Our aim was to elucidate the role of ACE2 as a pathophysiological risk factor by measuring soluble ACE2 (sACE2) via ELISA in blood samples (lithium-heparin-plasma or serum) of 367 individuals including children and adults with and without COVID-19. sACE2-levels were compared between the groups according to age and sex. In adults and children with COVID-19, sACE2-concentrations are significantly higher compared to healthy individuals. sACE2-levels increase with age and are lower in children compared to adults with COVID-19. Sex doesn't significantly influence sACE2-concentration. It remains unclear whether sACE2 concentrations increase because of the infection and what factors could influence this response. In conclusion, the increase of sACE2-concentration with age could indicate that ACE2 concentrations mirror increased COVID-19 severity.

: This study sought to assess how body mass (BM) and body composition in post-COVID-19 elderly adults were affected by 8 weeks of resistance training. An additional goal was to determine the agreement between Bioelectrical Impedance Analysis (BIA) and Dual Energy X-Ray Absorptiometry (DXA) in elderly people. : Participants were randomly assigned to an intervention Group, which engaged in 8 weeks of resistance training, and a Control Group, which was advised to maintain their usual activity levels.

: In Slovenia, patients with suspected tick-borne encephalitis (TBE) were historically referred to infectious diseases (ID), but during the COVID-19 pandemic, there were increased referrals to neurology. This study compared the clinical management of TBE patients between ID specialists and neurologists and assessed patients' outcomes. : We retrospectively reviewed the clinical, laboratory, and imaging data of 318 adult patients with TBE managed by ID (n = 256; 80.

Evidence suggests that older adults who survived COVID-19 were exposed to greater functional dependence in their daily living activities. This study aims to examine the prevalence of functional dependence and associated factors among Brazilian older people with functional dependence 12 months after COVID-19 infection. A cross-sectional study was carried out involving people aged 60 years or older in the state of Paraná, Brazil.

The continuous monitoring of oxygen saturation (SpO) and respiratory rates (RRs) are major clinical issues in many cardio-respiratory diseases and have been of tremendous importance during the COVID-19 pandemic. The early detection of hypoxemia was crucial since it precedes significant complications, and SpO follow-up allowed early hospital discharge in patients needing oxygen therapy. Nevertheless, fingertip devices showed some practical limitations.

Objectives: Gestational diabetes mellitus (GDM) is associated with an increased risk of both neonatal and maternal morbidity. The aim of this retrospective study was to evaluate the frequency of perinatal complications due to GDM in the Department of Neonatology at the Medical University of Wroclaw, Poland, considering the treatment of GDM-diet and physical activity versus insulin therapy. The influence of maternal comorbidities and the COVID-19 pandemic on pregnancy outcomes was assessed.
