Biomarkers.

Background: The nuclear clearance and cytoplasmic aggregation of splicing repressor TAR DNA/RNA-binding protein-43 (TDP-43) occur in approximately 50% of Alzheimer's disease (AD) cases and about 45% of frontotemporal dementia (FTD). However, it is not clear how early such mechanism occurs in AD and FTD as there is no method of detecting TDP-43 dysregulation in living individuals. Since the loss of nuclear TDP-43 leads to cryptic exon inclusion, we propose that cryptic exon-encoded peptides may be detected in patient biofluids as biomarkers of TDP-43 loss of function.

Expansion of stereotactic work envelope using transformation matrices and geometric algebra for neurosurgery.

Stereotactic systems have traditionally used Cartesian coordinate combined with linear algebraic mathematical models to navigate the brain. Previously, the development of a novel stereotactic system allowed for improved patient comfort, reduced size, and carried through a simplified interface for surgeons. The system was designed with a work envelope and trajectory range optimized for deep brain stimulation applications only.

The protective effects of liraglutide in reducing lipid droplets accumulation and myocardial fibrosis in diabetic cardiomyopathy.

Background: Diabetes is a primary contributor to diabetic cardiomyopathy (DbCM), which is marked by metabolic imbalances such as elevated blood glucose and lipid levels, leading to significant structural and functional alterations in the myocardium. Elevated free fatty acids (FFAs) and hyperglycemia play critical roles in DbCM development, with FFAs inducing insulin resistance in cardiomyocytes and promoting lipid accumulation, resulting in oxidative stress and fibrosis. Current research suggests that glucagon-like peptide-1 (GLP-1) receptor agonists may effectively mitigate DbCM, although an effective treatment for this condition remains elusive, and the precise mechanisms of this protective effect are not fully understood.

The additive impact of reduced symptom-to-door and door-to-balloon times on survival rates in acute ST-elevation myocardial infarction patients.

Background: Shortened door-to-balloon time (D2B) has been documented to confer cardiovascular benefits for ST-elevation myocardial infarction (STEMI) patients undergoing primary percutaneous coronary intervention (PPCI). However, prolonged myocardial ischemic duration usually negates the beneficial effects due to delayed symptom-to-door time (S2D). In this study, we sought to investigate the joint effect of S2D-D2B in predicting clinical outcomes.

Metabolic dysfunction-associated steatotic liver disease is associated with increased risks of heart failure.

Aims: Metabolic dysfunction-associated steatotic liver disease (MASLD), defined by steatotic liver disease (SLD) and cardiometabolic factors, is increasing in prevalence, but its association with heart failure (HF) is unclear.

Methods And Results: Patients with SLD without a history of HF from 2006 to 2021 were retrospectively included and were classified into MASLD and non-MASLD groups that were followed longitudinally. The primary outcome was the new development of HF, which was sub-classified by echocardiography.
