The association between stress hyperglycemia ratio and adverse outcomes in patients with chronic kidney disease: a systematic review and meta-analysis

Chronic kidney disease (CKD) increases risks of cardiovascular events and mortality, so reliable biomarkers are needed to improve risk stratification. Stress hyperglycemia ratio (SHR), which adjusts acute glucose levels for chronic glycemia using glycated hemoglobin, has shown pr...

Survival and biological and technical complications of veneered zirconia-ceramic versus metal-ceramic restorations: a systematic review and meta-analysis

This systematic review and meta-analysis aimed to critically assess and compare the survival rates and the spectrum of biological and technical complications associated with veneered zirconia-ceramic versus metal-ceramic restorations. By synthesizing evidence from randomized clin...

Comparative effectiveness of cognitive behavioral therapy versus group-based optimism training on psychological outcomes in hemodialysis patients: a randomized controlled trial

Patients undergoing hemodialysis (HD) face significant psychological challenges that affect their well-being. Nevertheless, no comparative investigation has yet examined the efficacy of cognitive-behavioral therapy (CBT) versus group-based optimism training on psychological outco...

Plasma p-tau217 as a two-cutoff approach to improve tau-PET screening and trial recruitment in Alzheimer’s disease

Abstract Blood-based biomarkers could broaden access to Alzheimer’s disease diagnostics, but their ability to approximate tau PET, and to address gray-zone results, remains uncertain. We evaluated plasma p-tau217 against tau PET using a harmonized ADNI baseline cohort and an inde...

Hepatic steatosis assessed by transient elastography in patients with significant coronary artery disease: a cross-sectional study

While metabolic dysfunction-associated steatotic liver disease (MASLD) and coronary artery disease (CAD) share metabolic risk factors, it remains unclear whether the anatomical severity of CAD predicts the severity of hepatic steatosis or fibrosis. This study aimed to estimate MA...

Background/Aims Occupational performance coaching is a family-centred intervention to enhance occupational performance in children. The remote variant, tele-occupational performance coaching, has become a viable option, especially for children with attention deficit hyperactivity...

Effect of a free sugar-restricted diet on anthropometric parameters, lipid profile, and glycemic control in women with polycystic ovary syndrome: a randomized controlled trial

Abstract Background High-sugar diets rich in fructose and other simple sugars are associated with increased lipogenesis and insulin resistance, potentially increasing the risk of metabolic syndrome, a condition closely linked with polycystic ovary syndrome (PCOS). This study aime...
