Global burden of disease attributable to metabolic risk factors in adolescents and young adults aged 15-39, 1990-2021.

Background: Metabolic risk factors are a significant cause of global burden among adolescents and young adults, but there is a lack of attention to the burden attributable to these metabolic risk factors globally.

Aims: This study aims to provide comprehensive estimates of five important metabolic risk factors and the attributable disease burden in people aged 15-39 years from 1990 to 2021, based on the Global Burden of Disease Study (GBD) database.

Methods: Global total deaths and disability-adjusted life years (DALYs) were used to describe the burden attributable to five common metabolic risk factors, including high fasting plasma glucose (FPG), high low-density lipoprotein cholesterol (LDL-C), high systolic blood pressure (SBP), high body mass index (BMI), and kidney dysfunction, in adolescents and young adults.

Peptides in the detection of metal ions.

By means of their specific interactions with different metal ions, naturally occurring proteins control structures and functions of many biological processes and functions in organisms. In view of natural metallopeptides, scientists have proposed artificial peptides which coordinate with metal ions through their functional groups either for introducing a special reactivity or for constructing various sensors. However, the design of new peptide ligands requires a deep understanding of the structures, assembly properties, and dynamic behaviors of such peptides.

Global burden of metabolic diseases, 1990-2021.

Background: Common metabolic diseases, such as type 2 diabetes mellitus (T2DM), hypertension, obesity, hypercholesterolemia, and metabolic dysfunction-associated steatotic liver disease (MASLD), have become a global health burden in the last three decades. The Global Burden of Disease, Injuries, and Risk Factors Study (GBD) data enables the first insights into the trends and burdens of these metabolic diseases from 1990 to 2021, highlighting regional, temporal and differences by sex.

Methods: Global estimates of disability-adjusted life years (DALYs) and deaths from GBD 2021 were analyzed for common metabolic diseases (T2DM, hypertension, obesity, hypercholesterolemia, and MASLD).

Clinical characteristics and prognostic importance of anticoagulant use in ischemic left ventricular aneurysm: a retrospective cohort study.

There is insufficient data on systemic embolic events (SSEs) in patients with ischemic left ventricular aneurysm (LVA) concerning the impact of anticoagulation therapy. In this retrospective cohort study with 1043 patients with ischemic LVA, SSEs occurred in 7.2% over 2.

Screening for metabolic dysfunction-associated fatty liver disease: Time to discard the emperor's clothes of normal liver enzymes?

Metabolic dysfunction-associated fatty liver disease (MAFLD) is the most prevalent chronic liver condition worldwide. Current liver enzyme-based screening methods have limitations that may missed diagnoses and treatment delays. Regarding Chen , the risk of developing MAFLD remains elevated even when alanine aminotransferase levels fall within the normal range.

Quantifying Microstructure Features for High-Performance Solid Oxide Cells.

The drive for sustainable energy solutions has spurred interest in solid oxide fuel cells (SOFCs). This study investigates the impact of sintering temperature on SOFC anode microstructures using advanced 3D focused ion beam-scanning electron microscopy (FIB-SEM). The anode's ceramic-metal composition significantly influences electrochemical performance, making optimization crucial.
