Brief communication: gaps and opportunities in HIV research in Venezuela.

Over the past decade, Venezuela has experienced a political and economic crisis that has affected the country's scientific research development. Currently, the state of HIV research in Venezuela remains unknown. We conducted a systematic review identifying 683 articles over the last 20 years of which only 101 met our inclusion criteria.

Psychotic-Spectrum Disorders With Comorbid Anxiety are Predisposing Factors for Parkinson's Disease in a Case-Control Study.

Background: Multiple studies have demonstrated associations between psychiatric conditions and Parkinson's disease (PD) development; fewer have examined psychotic-spectrum disorders and PD development.

Objective: The objective was to assess the prevalence of psychotic-spectrum disorders with and without depression and anxiety preceding a PD diagnosis.

Methods: In this retrospective, case-control study of adults > 60 years of age, cases were identified by PD diagnosis and controls were identified in a 3:1 ratio by ambulatory encounter from 2015 to 2020.

Orthotopic Heart Transplantation in a Patient With Hypertrophic Cardiomyopathy and Marfan Syndrome.

A 24-year-old man with Marfan syndrome and heart failure from hypertrophic cardiomyopathy was referred to our institution in cardiogenic shock for advanced therapies. He was supported by a femoral intra-aortic balloon pump, then bridged to orthotopic heart transplantation. This is a report of an orthotopic heart transplantation in a patient with both Marfan syndrome and heart failure from hypertrophic cardiomyopathy.

Artificial intelligence applied to bed regulation in Rio Grande do Norte: Data analysis and application of machine learning on the "RegulaRN Leitos Gerais" platform.

Bed regulation within Brazil's National Health System (SUS) plays a crucial role in managing care for patients in need of hospitalization. In Rio Grande do Norte, Brazil, the RegulaRN Leitos Gerais platform was the information system developed to register requests for bed regulation for COVID-19 cases. However, the platform was expanded to cover a range of diseases that require hospitalization.

Structural and functional insights into UDP-N-acetylglucosamine-enolpyruvate reductase (MurB) from Brucella ovis.

The peptidoglycan biosynthetic pathway involves a series of enzymatic reactions in which UDP-N-acetylglucosamine-enolpyruvate reductase (MurB) plays a crucial role in catalyzing the conversion of UDP-N-acetylglucosamine-enolpyruvate (UNAGEP) to UDP-N-acetylmuramic acid. This reaction relies on NADPH and FAD and, since MurB is not found in eukaryotes, it is an attractive target for the development of antimicrobials. MurB from Brucella ovis, the causative agent of brucellosis in sheep, is characterized here.
