Standard enhancement settings used on endoscopy systems significantly impair performance of artificial intelligence systems in endoscopy.

Background AI-systems in endoscopy are predominantly developed and tested using high-quality imagery from expert centers. Their performance may be different when applied on heterogeneous imagery in clinical practice. This is partially caused by the diversity in post-processing enhancement settings used in endoscopy units.

Multidimensional Analysis of Preoperative Patient-Reported Outcomes Identifies Distinct Phenotypes in Total Knee Arthroplasty: Secondary Analysis of the SHARKS Registry in a Public Hospital Department.

Anti-platelet factor 4 antibody-mediated disorders: an updated narrative review.

Anti-platelet factor 4 (PF4) antibody-mediated disorders are a heterogenous group of diseases characterized by the presence of highly pathogenic immunoglobulins G directed against PF4 and/or PF4/heparin complexes. These antibodies are able to activate platelets, neutrophils and monocytes, thus resulting in thrombocytopenia and a hypercoagulable state. Five different forms of anti-PF4 antibody-mediated disorders have been identified: i) classic heparin-induced thrombocytopenia (cHIT) mediated by heparin and certain polyanionic drugs; ii) autoimmune HIT (aHIT) characterized by the presence of anti-PFA/polyanion antibodies that can strongly activate platelets even in the absence of heparin; iii) spontaneous HIT (spHIT) characterized by thrombocytopenia and thrombosis without proximate exposure to heparin, with two subtypes: (a) post-total knee arthroplasty, and cardiac surgery using cardiopulmonary bypass or extracorporeal membrane oxygenation, and (b) post-infections; iv) vaccine-induced immune thrombotic thrombocytopenia (VITT) characterized by thrombocytopenia, arterial and venous thrombosis, or secondary hemorrhage after receiving adenoviral vector vaccines for COVID-19; v) VITT-like disorders triggered by adenoviral infections.

Experience using conventional compared to ancestry-based population descriptors in clinical genomics laboratories.

Various scientific and professional groups, including the American Medical Association (AMA), American Society of Human Genetics (ASHG), American College of Medical Genetics (ACMG), and the National Academies of Sciences, Engineering, and Medicine (NASEM), have appropriately clarified that certain population descriptors, such as race and ethnicity, are social and cultural constructs with no basis in genetics. Nevertheless, these conventional population descriptors are routinely collected during the course of clinical genetic testing and may be used to interpret test results. Experts who have examined the use of population descriptors, both conventional and ancestry based, in human genetics and genomics have offered guidance on using these descriptors in research but not in clinical laboratory settings.

Competitive behaviors in Serratia marcescens are coordinately regulated by a lifestyle switch frequently inactivated in the clinical environment.

Opportunistic bacterial pathogens must compete with other bacteria and switch between host- and environment-adapted states. Type VI secretion systems (T6SSs) occur widely in gram-negative bacteria and can efficiently kill neighboring competitors. We determined the distribution of T6SSs across the genus Serratia and observed that a highly conserved antibacterial T6SS is differentially active between closely related clinical isolates of Serratia marcescens.

Identification, structure, and agonist design of an androgen membrane receptor.

Androgens, such as 5α-dihydrotestosterone (5α-DHT), regulate numerous functions by binding to nuclear androgen receptors (ARs) and potential unknown membrane receptors. Here, we report that the androgen 5α-DHT activates membrane receptor GPR133 in muscle cells, thereby increasing intracellular cyclic AMP (cAMP) levels and enhancing muscle strength. Further cryoelectron microscopy (cryo-EM) structural analysis of GPR133-Gs in complex with 5α-DHT or its derivative methenolone (MET) reveals the structural basis for androgen recognition.

Triglyceride-glucose index and triglyceride-glucose-body mass index as prognostic factors for early stage breast cancer patients receiving neoadjuvant chemotherapy.

Background: Insulin resistance (IR) is closely associated with the risk of breast cancer. The triglyceride-glucose (TyG) index and the triglyceride-glucose-body mass index (TyG-BMI) are considered surrogate indicators of IR; however, their prognostic value in breast cancer patients has not been discussed. The purpose of this study is not only to explore whether the TyG index and the TyG-BMI can predict the chemotherapy response and long-term prognosis of breast cancer patients receiving neoadjuvant chemotherapy (NACT) but also to investigate the possible mediating mechanism and to analyze the relationship between TyG-related enzyme expression and drug resistance and prognosis.
