Risk of mycobacterial infections in a cohort of silicosis patients with autoimmune rheumatic diseases.

Objective: To evaluate the incidence rates of mycobacterial infections in silicosis patients with systemic autoimmune rheumatic disease (ARD).

Methods: This was a retrospective cohort of silicosis patients between January of 1999 and December of 2023. We compared the incidence of tuberculosis and nontuberculous mycobacterial disease (NTM) in patients with silicosis with and without ARD.

Amphisbaena lumbricalis Vanzolini, 1996 is a synonym of Amphisbaena carvalhoi Gans, 1965 (Squamata, Amphisbaenidae).

We reassessed the type-series of Amphisbaena lumbricalis Vanzolini, 1996 and Amphisbaena carvalhoi Gans, 1965, two small amphisbaenid species from northeastern Brazil, to evaluate the characters used to diagnose and distinguish them, and compared these data with additional specimens from four new localities. We found broadly overlapping ranges of the diagnostic characters, and no morphological traits that could support differences between A. carvalhoi and A.

Prognostic significance of gastrointestinal dysfunction in critically ill patients with COVID-19.

Objective: To analyze in-hospital and 1-year morbidity and mortality associated with acute gastrointestinal dysfunction in critically ill patients with COVID-19 via a prespecified scoring system.

Methods: Between March and July 2020, consecutive hospitalized patients with COVID-19 from a single institution were retrospectively analyzed by medical chart review. Only those who remained in the intensive care unit for more than 24 hours were included.

Addressing Conservation Needs: Genetic Diversity and Population Ecology of the Endemic Tree Arruda.

Arruda (Anacardiaceae), popularly known as umbuzeiro or imbuzeiro, is a fruit tree native to the semiarid region of Brazil. The extractive harvesting of its fruits contributes significantly to the economy, generating an annual revenue of approximately $4,2 million. The present study aimed to assess the spatial pattern, allometric variations, fruit measurements, and genetic diversity of trees within a remaining forest of the Caatinga biome, with a focus on intrapopulation analysis.

A Unique Enoxaparin Derived from Bovine Intestinal Heparin: A Single Purification Step of the Starting Material Assures a Bovine Enoxaparin Like the Standard from Porcine Origin.

Low-molecular-weight heparin represent a significant advancement in anticoagulant therapy with enoxaparin being a prominent example obtained exclusively through the fragmentation of porcine intestinal heparin. However, escalating demand and limited resources have raised concerns about enoxaparin supplementation. The current challenge involves exploring alternative heparin sources for large-scale enoxaparin production with bovine intestinal heparin emerging as a promising option.
