Cardiovascular disease and type 2 diabetes in older adults: a combined protocol for an individual participant data analysis for risk prediction and a network meta-analysis of novel anti-diabetic drugs
medRxiv20234 influential citationsIntroduction Older and multimorbid adults with type 2 diabetes (T2D) are at high risk of cardiovascular disease (CVD) and chronic kidney disease (CKD). Estimating risk and preventing CVD is a challenge in this population notably because it…
The role of antimicrobial prophylaxis in the management of snakebite: a systematic review
Wellcome Open Res2026n=6961 influential citationsBackground Snakebite, a neglected tropical disease disproportionately affecting lower-income countries, is a significant cause of morbidity and mortality worldwide. Local toxicity and necrosis may result in secondary bacterial infection of…
Probiotics for preventing or treating COVID-19; a systematic review of research evidence and meta-analyses of efficacy for preventing death, severe disease, or disease progression
Wellcome Open Res20221 influential citationsBackground: COVID-19 variants threaten health globally. Despite improving vaccines and treatments, there is an urgent need for alternative strategies to prevent or reduce the severity of COVID-19. Potential strategies include probiotics,…
Semaglutide-associated risk of nonarteritic anterior ischemic optic neuropathy in patients with type 2 diabetes: A systematic review and meta-analysis of observational studies.
PLoS medicine2026ESemaglutide, a glucagon-like peptide-1 receptor agonist, is widely used for the management of type 2 diabetes (T2DM). Recent case reports have raised concerns about a potential association between semaglutide use and the development of…
Tirzepatide as Adjunct to Insulin in Adults With Type 1 Diabetes and Overweight or Obesity: A Systematic Review of Randomized and Real-World Evidence.
Endocrinology, diabetes & metabolism2026n=250AOverweight and obesity are increasingly common in adults with type 1 diabetes (T1D), contributing to insulin resistance, higher insulin requirements, and greater cardiometabolic burden. Tirzepatide, a dual glucose-dependent insulinotropic…
Direct Oral Anticoagulants Versus Warfarin in Atrial Fibrillation With Advanced Chronic Kidney Disease: A Systematic Review and Meta-Analysis.
Cureus2026n=184,136DPatients with non-valvular atrial fibrillation (AF) and advanced chronic kidney disease (CKD), including those with end-stage kidney disease (ESKD) on dialysis, present a unique therapeutic challenge. This population is at an elevated risk…
A new framework for acupoint specificity: Advancing acupuncture studies using the double-dissociation model
Integrative Medicine Research2026Acupoint specificity is a central concept in traditional acupuncture theory but remains controversial in modern scientific studies. Methodological inconsistencies and a predominant reliance on single-dissociation approaches have…
Colorimetric Chemosensors for selective detection of arsenite and arsenate: DFT studies and application in water samples
Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy2026The study focuses on developing colorimetric chemosensors that selectively detects arsenite (AsO<sub>2</sub><sup>-</sup>) and arsenate (AsO<sub>4</sub><sup>3-</sup>) anions. Three furan-based colorimetric chemosensors, NCV1, NCV2 and NCV3…
Clinic-based cross-sectional observational study of factors associated with canine parvovirus breakthrough infection among gastroenteritis cases in Nigeria
Preventive Veterinary Medicine2026n=17Canine parvovirus (CPV) enteritis is a widespread infectious disease affecting dogs globally. While vaccination is an acceptable preventive measure, repeated cases of vaccination and immunization failures abound globally, posing a…
In Silico discovery of GES-5 inhibitors via molecular docking, molecular dynamics simulation studies, and ADMET prediction
Computational Biology and Chemistry2026The emergence of multidrug-resistant Enterobacteriaceae represents a major threat to global public health. Among the key resistance mechanisms, the production of β-lactamases enzymes that hydrolyze the β-lactam ring plays a central role in…
