Increase in new-onset type 1 diabetes diagnoses among Brazilian children and adolescents during the COVID-19 pandemic.

Objective: This study aimed to determine if there was a rise in new T1DM cases in children during the pandemic in a large metropolitan area in Brazil.

Methods: The authors conducted a cross-sectional study at five public tertiary care centers that specialize in diabetes in children, comparing all new T1DM cases (ages 0.5-18y) diagnosed from March 2020 to December 2021 (pandemic period, PP) with those from March 2018 to December 2019 (historical period, HP).

Lidocaine exhibits antileishmanial and immunomodulatory activities in an in vitro model of tegumentary leishmaniasis.

Local anesthetics have been shown to inhibit or delay the progression of tegumentary leishmaniasis (TL) in hamster models, although the mechanisms underlying this clinical improvement remain unclear. This study aimed to determine whether lidocaine reduces intracellular parasitism through a direct antiparasitic effect and/or by modulating macrophage functions. To achieve this, Leishmania (L.

Lack of association between Y chromosome haplogroups and male infertility in Japanese men.

The Y chromosome carries several genes involved in spermatogenesis, which are distributed in three regions in the euchromatic part of the long arm, called AZFa (azoospermia factor a), AZFb, and AZFc. Microdeletions in these regions have been seen in 10-15% of sterile males with azoospermia or severe oligozoospermia. The relatively high de novo occurrence of these microdeletion events might be due to particular chromosome arrangements associated with certain Y chromosome haplogroups.
