Dietary patterns derived by reduced rank regression, macronutrients as response variables, and variation by economic status: NHANES 1999-2018.
EUROPEAN JOURNAL OF NUTRITION - 17 Sep 2024
Macronutrient intakes vary across people and economic status, leading to a disparity in diet-related metabolic diseases. This study aimed to provide insight into this by: (1) identifying dietary patterns in adults using reduced rank regression (RRR), with macronutrients as response variables, and (2) investigating the associations between economic status and macronutrient based dietary patterns...
Cyclic stretch enhances neutrophil extracellular trap formation.
BMC BIOLOGY - 18 Sep 2024
Neutrophils, the most abundant leukocytes circulating in blood, contribute to host defense and play a significant role in chronic inflammatory disorders. They can release their DNA in the form of extracellular traps (NETs), which serve as scaffolds for capturing bacteria and various blood cells. However, uncontrolled formation of NETs (NETosis) can lead to excessive activation of coagulation pa...

Protective role of acetylcholine and the cholinergic system in the injured heart.
ISCIENCE - 20 Sep 2024
This review explores the roles of the cholinergic system in the heart, comprising the neuronal and non-neuronal cholinergic systems. Both systems are essential for maintaining cardiac homeostasis by regulating the release of acetylcholine (ACh). A reduction in ACh release is associated with the early onset of cardiovascular diseases (CVDs), and increasing evidence supports the protective roles ...

HIV-1-DNA/RNA and immunometabolism in monocytes: contribution to the chronic immune activation and inflammation in people with HIV-1.
EBIOMEDICINE - 11 Sep 2024
Among people living with HIV-1 (PHIV), immunological non-responders (INR) experience incomplete immune recovery despite suppressive antiretroviral treatment (ART), facing more severe non-AIDS events than immunological responders (IR) due to higher chronic immune activation and inflammation (cIA/I). We analyzed the HIV-1 reservoir and immunometabolism in monocytes as a source of cIA/I. Cross-sec...
Tree-based scan statistics to generate drug repurposing hypotheses: a test case using sodium-glucose cotransporter-2 inhibitors.
11 Sep 2024
Most drug repurposing studies using real-world data focused on validating, instead of generating, hypotheses. We used tree-based scan statistics to generate repurposing hypotheses for sodium-glucose cotransporter-2 inhibitors (SGLT2i). We used an active-comparator, new-user design to create a 1:1 propensity-score matched cohort of SGLT2i and dipeptidyl peptidase-4 inhibitors (DPP4i) initiators ...
Evaluating the cost-effectiveness of polygenic risk score-stratified screening for abdominal aortic aneurysm.
NATURE COMMUNICATIONS - 14 Sep 2024
As the heritability of abdominal aortic aneurysm (AAA) is high and AAA partially shares genetic architecture with other cardiovascular diseases, genetic information could help inform AAA screening strategies. Exploiting pleiotropy and meta-analysing summary data from large studies, we construct a polygenic risk score (PRS) for AAA. Leveraging related traits improves PRS performance (R<sup>2</su...
High-density lipoprotein cholesterol level and risk of muscle strength decline and sarcopenia in older adults.
CLINICAL NUTRITION (EDINBURGH, SCOTLAND) - 22 Aug 2024
Recent studies have demonstrated that very high high-density lipoprotein cholesterol (HDL-C) level was paradoxically linked with higher risk of cardiovascular mortality, all-cause mortality, and several age-related diseases. However, whether very high HDL-C level is associated with a higher risk of sarcopenia in older adults remains unclear. We aimed to investigate the association between HDL-C...
