Precision Medicine for Pulmonary Vascular Disease: The Future Is Now (2023 Grover Conference Series).

Pulmonary vascular disease is not a single condition; rather it can accompany a variety of pathologies that impact the pulmonary vasculature. Applying precision medicine strategies to better phenotype, diagnose, monitor, and treat pulmonary vascular disease is increasingly possible with the growing accessibility of powerful clinical and research tools. Nevertheless, challenges exist in implementing these tools to optimal effect.

Sexual selection promotes reproductive isolation in barn swallows.

Despite the well-known effects of sexual selection on phenotypes, links between this evolutionary process and reproductive isolation, genomic divergence, and speciation have been difficult to establish. We unravel the genetic basis of sexually selected plumage traits to investigate their effects on reproductive isolation in barn swallows. The genetic architecture of sexual traits is characterized by 12 loci on two autosomes and the Z chromosome.

Cognitive Behavioral Therapy Factors Related to Outcomes in Depression Among Youth with HIV.

Purpose: This is a secondary analysis of a multi-site, cluster (site) randomized trial of the efficacy of a combined Health and Wellness Cognitive Behavior Therapy (H&W CBT) and medication management approach for depression in youth with HIV (YWH) compared to standard care. In this study, we explored the association between H&W CBT factors and depression outcomes after 24 weeks of treatment to discover treatment elements associated with symptom reduction.

Methods: Participants (12-24 years of age) were YWH in the United States (US) diagnosed with moderate to severe depression [Quick Inventory of Depressive Symptomatology (QIDS), Clinician-Rated score ≥ 11].

Deep phenotyping the right ventricle to establish translational MRI biomarkers for characterization of adaptive and maladaptive states in pulmonary hypertension.

Deep phenotyping the right ventricle (RV) is essential for understanding the mechanisms of adaptive and maladaptive RV responses to pulmonary hypertension (PH). In this study, feature selection coupled with machine learning classification/ranking of specific cardiac magnetic resonance imaging (MRI) features from cine-MRI, flow-sensitized, and extracellular-volume techniques were used to assess RV remodelling in monocrotaline (MCT) and Sugen hypoxia (SuHx) PH rats. Early physiological changes associated with RV adaptation were detected along with prediction of RV maladaptive outcomes.

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).
