A newly bat-borne hantavirus detected in Seba's short-tailed bats (Carollia perspicillata) in the Brazilian Atlantic Rainforest.

Background: Bat-borne hantaviruses have been identified worldwide but little is known about neotropical bats in the megadiverse biomes of the American continent. Although serological evidence has hinted at hantavirus circulation in Brazil, the scarce number of genomic detection represents a gap to understand viral diversity, prevalence, and ecology of bat-borne hantaviruses.

Objective: We aim to investigate and evaluate the presence and prevalence of bat-borne hantavirus in the Brazilian Atlantic Forest.

Urethral instrumentation in men with artificial urinary sphincter: a national survey among Brazilian urologists.

Purpose: Urethral instrumentation (UI) in patients with an artificial urinary sphincter (AUS) demands technical considerations and poses a risk of urethral erosion, leading to serious clinical and legal consequences. We conducted a national survey to evaluate the knowledge and experience of Brazilian urologists with UI in these patients.

Methods: This study used an electronic survey distributed to members of the Brazilian Society of Urology.

Homologous acetylenic acetogenins from Porcelia macrocarpa R.E. (Fries) displayed potent activity against amastigotes from Trypanosoma cruzi.

As part of our continuous study on the Annonaceae species Porcelia macrocarpa, in the present work, eight chemically related 2-alkyl-3-hydroxy-4-methyl-γ-lactones (1-8) were isolated. Their structures were characterised by NMR, MS, and VCD. Their antitrypanosomal activity was evaluated in vitro against intracellular amastigotes with EC values ranged from 13.

Tract-specific spinal damage in SCA2, SCA3 and SCA6.

Background: Spinocerebellar ataxias (SCAs) are a group of neurodegenerative disorders characterized by progressive ataxia. Although previous studies have focused on cerebral and cerebellar damage, spinal cord involvement in SCAs remains underexplored.

Objectives: This study aims to characterize spinal cord abnormalities in SCA2, SCA3, and SCA6 and to identify its phenotypic correlates.

Median nerve impairment in leprosy: how does it differ from the classic carpal tunnel syndrome?

Background:  Carpal tunnel syndrome (CTS) has already been described as a possible form of neural leprosy presentation. However, the median nerve can be involved in this neuropathy in proximal segments and, sometimes, with an asymmetric impairment of the digital branches.

Objective:  To detail the pattern of median nerve impairment through nerve conduction study (NCS) and ultrasound evaluation.
