The discovery and study of three new species of from Southwestern North America, , , and , adds not only to the diversity of the genus and family but generated new insights into the occurrence of two ascus types in the genus and the variety of conidiogenous cells and conidia. now includes 15 species with a mainly Holarctic distribution (Asia, Europe, North America) and one species in Australia. A key is supplied to the genus. An overview of the genus is given, including differentiation from other genera of Acarosporaceae. The monotypic genus is considered to be a synonym of . The new combination is proposed. The ascus type is shown to be variable in the genus with species with two types being intermixed with each other in our phylogeny.

Background: Xylazine is a α2-adrenergic receptor agonist, used for sedation in veterinary contexts. Although it is increasingly found in overdose deaths across North America, the clinical management of xylazine-involved overdoses has not been extensively studied, especially in community-based harm reduction settings. Here we present a clinical series of xylazine-involved overdose and share the clinical approach and lessons learned by a community overdose response team in Tijuana, Mexico amidst the arrival of xylazine.

The public health risks of counterfeit pills.

Lancet Public Health

Synthetic illicit drugs, such as nitazenes and fentanyls, are becoming commonplace in countries around the world, including in Europe, Australia, and Latin America, which raises concern for overdose crises like those seen in North America. An important dimension of the risk represented by synthetic drugs is the fact that they are increasingly packaged in counterfeit pill form. These pills-often indistinguishable from authentic pharmaceuticals-have substantially widened the scope of populations susceptible to synthetic drug overdose in North America (eg, among adolescents experimenting with pills or tourists from the USA seeking psychoactive medications from pharmacies in Mexico).

Objective: To evaluate the worldwide use of FIGO's two systems for the classification of causes and contributors to nongestational abnormal uterine bleeding in the reproductive years by obstetrics and gynecology professionals worldwide, to identify knowledge gaps, and explore barriers to implementation.

Methods: An electronic survey was developed by members of FIGO's Menstrual Disorders and Related Health Impacts (MDRHI) Committee to assess knowledge of abnormal uterine bleeding (AUB) and the two FIGO AUB systems among obstetricians and gynecologists. The survey was conducted online from February 28 to June 30, 2023, and comprised demographic questions, educational content inquiries, and a knowledge assessment.
