A functional microbiome catalogue crowdsourced from North American rivers.

Predicting elemental cycles and maintaining water quality under increasing anthropogenic influence requires knowledge of the spatial drivers of river microbiomes. However, understanding of the core microbial processes governing river biogeochemistry is hindered by a lack of genome-resolved functional insights and sampling across multiple rivers. Here we used a community science effort to accelerate the sampling, sequencing and genome-resolved analyses of river microbiomes to create the Genome Resolved Open Watersheds database (GROWdb).

An integrated approach to evaluating water contaminants and evaporation in agricultural water distribution systems.

This study presents an innovative approach for assessing water quality in agricultural irrigation networks, integrating stable isotope analysis, in vivo zebrafish screening, and comprehensive chemical profiling to investigate the occurrence, transformation, and potential toxicity of organic contaminants. Stable isotope analysis was used to measure evaporation as a proxy for water residence time in the canal, while liquid chromatography-high resolution mass spectrometry (LC-HRMS) identified a range of organic compounds in water samples collected from both the irrigation canal and its source river. Results indicated a reduction in contaminant levels in the canal compared to the river, with the most significant evaporation and concentration changes occurring at a holding reservoir, suggesting that managing residence time could help reduce water loss in arid irrigation networks.

Anti-retinal Autoantibodies in Hydroxychloroquine Eye Toxicity.

Objective: Autoimmune retinopathy and hydroxychloroquine (HCQ)-related retinal toxicity share many similarities, raising the possibility autoimmunity plays a role in HCQ retinopathy. The objective of this study is to determine whether patients diagnosed with HCQ retinal toxicity are more likely to have circulating antiretinal autoantibodies (AAbs) compared to controls.

Methods: We tested plasma samples for the presence of anti-retinal AAbs by immunoblotting in 270 patients with systemic lupus erythematosus (SLE) receiving HCQ.

A scoping review of the epidemiology of systemic sclerosis and its organ manifestations: 2018-2024.

Purpose Of Review: Updates from large, observational cohorts and new statistical techniques have resulted in new data on the epidemiology of systemic sclerosis (SSc). This scoping review uses data from 2018 to 2024 to describe the current understanding of the epidemiology of SSc and several of its organ- manifestations.

Recent Findings: Our review identified new estimates for the global incidence and prevalence of SSc (1.

Objective: To obtain an overview of current practice for pre-alveolar bone graft (pre-ABG) orthodontics at cleft centres across the United Kingdom.

Design: Cross-sectional survey.

Setting: Web-based.
