Allogenic faecal microbiota transplantation for antibiotic-associated diarrhoea in critically ill patients (FEBATRICE)-Study protocol for a multi-centre randomised controlled trial (phase II).

Background: Exposure of critically ill patients to antibiotics lead to intestinal dysbiosis, which often manifests as antibiotic-associated diarrhoea. Faecal microbiota transplantation restores gut microbiota and may lead to faster resolution of diarrhoea.

Methods: Into this prospective, multi-centre, randomized controlled trial we will enrol 36 critically ill patients with antibiotic-associated diarrhoea.

The impact of new onset diabetes on cardiovascular risks in orthotopic liver transplant recipients: findings from the COLT study.

Background: Orthotopic liver transplantation (OLT) has greatly improved short-term survival for end-stage liver disease. However, cardiovascular events (CVE) still pose a significant threat to long-term post-transplant health. Aim of this study is to assess the occurrence of long-term cardiovascular events and whether it relates to new-onset diabetes after liver transplantation (NODALT).

Development and evaluation of a web-based diet quality screener for vegans (VEGANScreener): a cross-sectional, observational, multicenter, clinical study.

Consumption of plant-based diets, including vegan diets, necessitates attention to the quality of the diet for the prevention and early detection of nutritional deficiencies. Within the VEGANScreener project, a unique brief screening tool for the assessment and monitoring of diet quality among vegans in Europe was developed. To provide a standardized tool for public use, a clinical study will be conducted to evaluate the VEGANScreener against a reference dietary assessment method and nutritional biomarkers.

Liver fat response to two days fasting and two days isocaloric high-carbohydrate refeeding in lean and obese women.

Background And Aims: Prolonged fasting, which leads to the mobilization of fat from adipose tissue, can result in the development of hepatosteatosis. However, it is not yet known whether the accumulation of fat in the liver after fasting can be affected by concurrent obesity. Therefore, this study aimed to assess how excessive adiposity influences changes in liver fat content induced by fasting and subsequent refeeding.

Evaluating Bacterial Viability in Faecal Microbiota Transplantation: A Comparative Analysis of In Vitro Cultivation and Membrane Integrity Methods.

Background: Faecal microbiota transplantation (FMT) is a developing therapy for disorders related to gut dysbiosis. Despite its growing application, standardised protocols for FMT filtrate preparation and quality assessment remain undeveloped. The viability of bacteria in the filtrate is crucial for FMT's efficacy and for validating protocol execution.

The impact of the massive open online course C19_SPACE during the COVID-19 pandemic on clinical knowledge enhancement: a study among medical doctors and nurses.

Purpose: During the initial phase of the pandemic, healthcare professionals faced difficulties due to the limited availability of comprehensive learning resources on managing patients affected with coronavirus disease 2019 (COVID-19). The COVID-19 Skills Preparation Course (C19_SPACE) was tailored to meet the overwhelming demand for specialized training. The primary objective of this study was to assess the efficacy and impact of this program on enhancing clinical knowledge and to identify factors affecting this improvement.

Obesity alters adipose tissue response to fasting and refeeding in women: A study on lipolytic and endocrine dynamics and acute insulin resistance.

Fasting induces significant shifts in substrate utilization with signs of acute insulin resistance (IR), while obesity is associated with chronic IR. Nonetheless, both states substantially influence adipose tissue (AT) function. Therefore, in this interventional study (NCT04260542), we investigated if excessive adiposity in premenopausal women alters insulin sensitivity and AT metabolic and endocrine activity in response to a 60-h fast and a subsequent 48-h refeeding period.

SARS-CoV-2 viral load is linked to remdesivir efficacy in severe Covid-19 admitted to intensive care.

Remdesivir therapy has been declared as efficient in the early stages of Covid-19. Of the 339 patients (males 55.8%, age 71(59;77) years) with a detectable viral load, 140 were treated with remdesivir (of those 103 in the ICU and 57 immunosuppressed) and retrospectively compared with 199 patients (of those 82 in the ICU and 28 immunosuppressed) who were denied therapy due to advanced Covid-19.

Real-World Data on Brodalumab Treatment in Patients with Moderate-to-Severe Plaque Psoriasis: An Observational Study from the Czech Republic BIOREP Registry.

Introduction: The aim of this observational, multicenter study was to assess the real-world use of brodalumab for the treatment of moderate-to-severe plaque psoriasis in patients in the Czech Republic, using data from the BIOREP registry.

Methods: The study included 273 patients aged ≥ 18 years with moderate-to-severe psoriasis who received brodalumab. Endpoints were drug survival (time from treatment initiation to discontinuation), effectiveness [Psoriasis Area and Severity Index (PASI)], and health-related quality-of-life [Dermatology Life Quality Index (DLQI)].

Predictors of spontaneous intracerebral hemorrhage mortality: a community-based study in Brno, Czech Republic.

Background And Objective: Intracerebral hemorrhage (ICH) is a serious medical condition with high mortality. However, factors leading to long-term mortality after ICH are largely unclear. The aim of this community-based study is to assess predictors of long-term mortality after spontaneous ICH.

Evaluation of adherence to abiraterone therapy in prostate cancer patients based on a population pharmacokinetic model.

Aims: Abiraterone treatment requires regular drug intake under fasting conditions due to pronounced food effect, which may impact patient adherence. The aim of this prospective study was to evaluate adherence to abiraterone treatment in patients with prostate cancer. To achieve this aim, an abiraterone population pharmacokinetic model was developed and patients' adherence has been estimated by comparison of measured levels of abiraterone with population model-based simulations.

Purpose: The echocardiography parameters may predict the maintenance of sinus rhythm after cardioversion of a supraventricular arrhythmia (SVA).

Materials And Methods: Patients in septic shock with onset of an SVA, normal to moderately reduced LV systolic function (EF_LV˃̳35%) and on a continuous noradrenaline of <1.0 μg/kg.

Feasibility of Direct Vitrectomy-Sparing Subretinal Injection for Gene Delivery in Large Animals.

Purpose: To assess the safety and feasibility of direct vitrectomy-sparing subretinal injection for gene delivery in a large animal model.

Methods: The experimental Liběchov minipigs were used for subretinal delivery of a plasmid DNA vector (pS/MAR-CMV-copGFP) with cytomegalovirus (CMV) promoter, green fluorescent protein (GFP) reporter (copGFP) and a scaffold/matrix attachment region (S/MAR) sequence. The eyes were randomized to subretinal injection of the vector following pars plana vitrectomy (control group) or a direct injection without prior vitrectomy surgery (experimental group).

β-hydroxybutyrate exposure restores mitochondrial function in skeletal muscle satellite cells of critically ill patients.

Background & Aim: Dysfunction of skeletal muscle satellite cells might impair muscle regeneration and prolong ICU-acquired weakness, a condition associated with disability and delayed death. This study aimed to elucidate the distinct metabolic effects of critical illness and β-OH-butyrate on satellite cells isolated from these patients.

Methods: Satellite cells were extracted from vastus lateralis muscle biopsies of patients with ICU-acquired weakness (n = 10) and control group of healthy volunteers or patients undergoing elective hip replacement surgery (n = 10).

BCAA metabolism in pancreatic cancer affects lipid balance by regulating fatty acid import into mitochondria.

Background: Pancreatic ductal adenocarcinoma (PDAC) has been associated with the host dysmetabolism of branched-chain amino acids (BCAAs), however, the implications for the role of BCAA metabolism in PDAC development or progression are not clear. The mitochondrial catabolism of valine, leucine, and isoleucine is a multistep process leading to the production of short-chain R-CoA species. They can be subsequently exported from mitochondria as short-chain carnitines (SC-CARs), utilized in anabolic pathways, or released from the cells.
