Chronic care manages long-term, progressive conditions, while acute care handles short-term ones. Here, authors show chronic conditions account for most of the global health burden, with 68% of DALYs and 93% of YLDs attributed to chronic care needs.

Whether multimorbidity accelerates brain Aβ deposition in humans remains largely unknown. Here, the authors demonstrate that higher self-reported multimorbidity burden predicts increased brain Aβ accumulation rates in the ADNI cohort.

Human neurons derived from induced pluripotent stem cells permit the study of aberrant protein processing and aggregation in Machado–Joseph disease.

Current models suggest that DLK1 is an inhibitory ligand in the Notch pathway. Here, the authors show that DLK1 does not interact with Notch receptors, instead blocking Activin signaling via an interaction with Activin receptor type-2B.

This study shows that glial reactivity is linked to synaptic dysfunction in aging and Alzheimer’s disease, with tau pathology mediating these effects–highlighting the potential of synaptic biomarkers track disease progression.

Genome-wide analyses identify 30 independent loci associated with obsessive–compulsive disorder, highlighting genetic overlap with other psychiatric disorders and implicating putative effector genes and cell types contributing to its etiology.

Study shows PTSD predisposition shares distinct genes and genomic regions with several cardiovascular conditions. Here the findings reveal neuronal, immune, and metabolic pathways, and repurposed drug targets that further the understanding of the comorbidity.

Literature produced inconsistent findings regarding the links between extreme weather events and climate policy support across regions, populations and events. This global study offers a holistic assessment of these relationships and highlights the role of subjective attribution.

Placing particles at the interface between immiscible fluids usually enhances emulsification. However, now it is shown that if the particles are ferromagnetic, emulsification is suppressed and a non-planar recoverable interfacial shape develops.

An analysis of 24,202 critical cases of COVID-19 identifies potentially druggable targets in inflammatory signalling (JAK1), monocyte–macrophage activation and endothelial permeability (PDE4A), immunometabolism (SLC2A5 and AK5), and host factors required for viral entry and replication (TMPRSS2 and RAB2A).

A genome-wide study by the Long COVID Host Genetics Initiative identifies an association between the FOXP4 locus and long COVID, implicating altered lung function in its pathophysiology.

Sarcomas are a group of mesenchymal malignancies which are molecularly heterogeneous. Here, the authors develop an in vivo muscle electroporation system for gene delivery to generate distinct subtypes of orthotopic genetically engineered mouse models of sarcoma, as well as syngeneic allograft models with scalability for preclinical assessment of therapeutics.

A global network of researchers was formed to investigate the role of human genetics in SARS-CoV-2 infection and COVID-19 severity; this paper reports 13 genome-wide significant loci and potentially actionable mechanisms in response to infection.

A two-step Bayesian model improves small area population estimates by integrating health campaign data or household surveys with incomplete satellite settlement maps. It reduces errors by up to 73%, offering a practical solution in regions where traditional methods face limitations.

Utilizing single-cell RNA sequencing, the authors here find that IL1B gene expression in peripheral blood monocytes associates with smaller HIV-1 reservoir size in people treated during acute infection, suggesting IL1B may be a natural latency reversing factor decreasing the reservoir via NF-κB activation.

The molecular etiology of hypertensive disorders of pregnancy is largely unknown. Here the authors show from a prospective study of diverse pregnancies that the disease can be split into molecular subtypes based on RNA data and validated a classifier for individuals with no preexisting high risk factors.

Multiomic analysis of blast-phase myeloproliferative neoplasms identifies a chromosome 21 amplicon harboring DYRK1A as a clonal and therapeutically targetable event in around a quarter of cases.

Inhibition of a cardiac stroma-enriched mechanosensor, SRC—in concert with suppression of the TGFβ pathway—potentiates the reversal of fibroblast activation and alleviates contractile dysfunction in fibrotic hearts.

Whole-genome sequencing, transcriptome-wide association and fine-mapping analyses in over 7,000 individuals with critical COVID-19 are used to identify 16 independent variants that are associated with severe illness in COVID-19.

Heart failure with preserved ejection fraction (HFpEF), which can be driven by obesity and hypertension, has a high prevalence but limited treatment options. Here, the authors show that nitro-oleic acid restores mitochondrial function and improves heart failure symptoms in a mouse model of HFpEF.

Heo, Xu et al. used comprehensive plasma proteomics to identify 416 plasma proteins (294 new) associated with Alzheimer’s disease and applied machine learning to select 7 proteins that were highly predictive of Alzheimer’s disease across multiple cohorts.

Microscopic colitis is a chronic inflammatory disease of the large intestine. Here the authors use single-cell RNA transcriptomic profiling and tissue localization studies to characterise the colon immune cell populations in MC, showing expansion of CD8 T cells with diverse TCR clonotypes and expression of CD4 T reg cell signatures.

Black and white fonio are two small indigenous grain cereals grown in West Africa. Here, the authors reveal their independent domestication and cultivation histories through population genetics and demographic history analyses.

A phase 1 feasibility trial shows that bilateral deep brain stimulation within the central lateral thalamus can be safely applied and is associated with improved executive control.

Influenza A H5N1 is an increasing concern in cattle herds in the United States. Here, the authors use mathematical modelling to estimate the size of the current epidemic, predict states at risk in the future, and highlight gaps in data collection.

A non-contact wearable device that defines and modulates a microclimate adjacent to the skin can measure incoming and outgoing streams of vapourized substances, offering valuable insights into physiological health, wound healing and environmental exposures.

Microglial states are dynamically regulated during development and disease. Here, the authors show that these changes are mediated by cell autonomous TGF-β signaling in microglia, which is developmentally regulated by ITGB8 in radial glia.

Xylem-mediated transport and light intensity on leaf surface primarily drive foliar methane oxidation and nitrous oxide emissions in Salix bebbiana plant, according to an analysis of an ecophysiological manipulation experiment with biochar incorporation and nitrogen addition.

Here, the authors suggest that nitric oxide (NO) is an endogenous epigenetic regulator of gene expression by inhibiting DNA demethylation enzymes (TET and ALKBH2) and increasing DNA methylation at gene regulatory loci throughout the genome.

Artificial intelligence (AI) system is known to improve dermatologists’ diagnostic accuracy for melanoma. This group applies the eye-tracking technology on dermatologists when diagnosing dermoscopic images of melanomas and reports improved balanced diagnostic accuracy when using an X(explainable) AI system comparing to the standard one.

Long-read chromatin assay reveals (1) a novel class of accessible chromatin regions, (2) accessibility within individual LTR retrotransposons and (3) the relationship between diffuse accessibility, gene body methylation and hAT transposon insertion.

Systematic analysis from the Global Burden of Disease study reported that, despite global improvements from 1990 to 2021, dietary iron deficiency-associated disease burden remains high in women, children and residents in low socio-demographic index countries.
