Distinct metabolic perturbations link liver steatosis and incident CVD in lean but not obese PWH.
Metabolic dysfunction-associated steatotic liver disease (MASLD) is a key risk factor for cardiovascular disease (CVD), potentially driven by shared metabolic mechanisms. Metabolic perturbations associated with MASLD and CVD remain underexplored in people with HIV (PWH). ⋯ Metabolic disturbances linked to liver steatosis and CVD diverge across BMI categories in PWH. Lean PWH, unlike their overweight/obese counterparts, show common metabolic perturbations between MASLD and CVD, particularly involving arachidonic acid metabolism. This suggests that lean PWH with liver steatosis may face a heightened risk of CVD due to shared metabolic pathways, potentially opening avenues for targeted interventions, such as aspirin therapy, to mitigate this risk.

Preventing cardiovascular disease (CVD) in adults with hypertension is essential, but it remains uncertain whether optimizing modifiable factors can eliminate the excess CVD risk associated with new-onset hypertension. ⋯ In adults with new-onset hypertension, maintaining four or more modifiable factors at favorable levels was associated with a CVD risk comparable to that of normotensive individuals. However, young hypertensive adults may require more aggressive interventions to mitigate CVD risk.

Generative artificial intelligence (GAI) has developed rapidly and been increasingly used in scholarly publishing, so it is urgent to examine guidelines for its usage. This cross-sectional study aims to examine the coverage and type of recommendations of GAI usage guidelines among medical journals and how these factors relate to journal characteristics. ⋯ Although most medical journals provided their own GAI usage guidelines or referenced external guidelines, some recommendations remained unspecified (e.g., whether AI can be used for data analysis and interpretation). Additionally, journals with lower SJR scores were less likely to provide guidelines, indicating a potential gap that warrants attention. Collaborative efforts are needed to develop specific recommendations that better guide authors and reviewers.

Sepsis-associated acute kidney injury (SA-AKI) is a frequent complication in patients with sepsis and is associated with high mortality. Therefore, early recognition of SA-AKI is essential for administering supportive treatment and preventing further damage. This study aimed to identify and validate metabolite biomarkers of SA-AKI to assist in early clinical diagnosis. ⋯ We proposed a blood metabolite model consisting of inosine, creatine, and 3-hydroxybutyric acid for the early screening of SA-AKI. Future studies will observe the performance of these metabolites in other clinical populations to evaluate their diagnostic role.

Fluoroquinolone antibiotics have a high potential for serious adverse drug reactions, but real-world evidence in European patient cohorts is lacking. Therefore, we aim to examine the association between fluoroquinolone exposure and potentially life-threatening adverse events stratified by age and gender in Germany. ⋯ This study contributes real-world evidence to endpoint-specific differences of risks in patient subgroups which need to be considered to improve fluoroquinolone drug safety.
