Women with pelvic organ prolapse and fibulin-5 rs12589592 polymorphism.

Objective: This study aims to access the frequency of single-nucleotide polymorphism rs12589592 (G>A) of the fibulin-5 gene in a Brazilian population with pelvic organ prolapse.

Methods: This was a case-control study, with menopausal women divided into two groups and classified using the pelvic organ prolapse quantification system: pelvic organ prolapse group: pelvic organ prolapse quantification system stages III and IV and Control group: pelvic organ prolapse quantification system stages I and 0. We collected epidemiologic and baseline health information and performed genotyping of rs12589592 from the fibulin-5 gene using a restriction fragment length polymorphism (polymerase chain reaction-restriction fragment length polymorphism) strategy, based on the distinction of sequences from alleles G and A by the restriction enzyme DdeI.

A Decade of Chronic Norovirus Infection Surveillance at the NIH Clinical Research Center: Clinical Characteristics, Molecular Epidemiology, and Replication.

Background: Noroviruses are an important viral cause of chronic diarrhea in immunocompromised individuals.

Method: We collected norovirus-positive stool samples (n=448) from immunocompromised patients (n=88) at the National Institutes of Health Clinical Research Center, U.S.

Trypanosoma cruzi Vps34 colocalizes with Beclin1 and plays a role in parasite invasion of the host cell by modulating the expression of a sub-group of trans-sialidases.

Trypanosoma cruzi, the etiological agent of Chagas' disease, can infect both phagocytic and non-phagocytic cells. T. cruzi gp82 and gp90 are cell surface proteins belonging to Group II trans-sialidases known to be involved in host cell binding and invasion.

Endoscopic treatment of anastomotic leakage after colorectal surgery by using polyglycolic acid sheets and fibrin glue.

We describe the case of a 66-year-old man with an anastomotic fistula after rectal surgery, which was treated colonoscopically using polyglycolic acid sheets and fibrin glue. Polyglycolic acid sheets and fibrin glue have been used in thoracic surgery and otolaryngology to reinforce sutures and prevent air leakage. There have been recent reports of their use in endoscopic surgery for the closure of intraoperative perforations after endoscopic submucosal dissection and for fistula closure after upper gastrointestinal tract surgery.

Using artificial intelligence to improve human performance: efficient retinal disease detection training with synthetic images.

Background: Artificial intelligence (AI) in medical imaging diagnostics has huge potential, but human judgement is still indispensable. We propose an AI-aided teaching method that leverages generative AI to train students on many images while preserving patient privacy.

Methods: A web-based course was designed using 600 synthetic ultra-widefield (UWF) retinal images to teach students to detect disease in these images.
