Article Abstract
Background And Purpose: Both low serum calcium and magnesium levels have been associated with the extent of bleeding in patients with intracerebral hemorrhage, suggesting hypocalcemia- and hypomagnesemia-induced coagulopathy as a possible underlying mechanism. We hypothesized that serum albumin-corrected total calcium and magnesium levels are associated with ruptured intracranial aneurysms.
Methods: The medical records of 4701 patients, including 1201 prospective patients, diagnosed at the Brigham and Women's Hospital and Massachusetts General Hospital between 1990 and 2016 were reviewed and analyzed. One thousand two hundred seventy-five patients had available serum calcium, magnesium, and albumin values within 1 day of diagnosis. Individuals were divided into cases with ruptured aneurysms and controls with unruptured aneurysms. Univariable and multivariable logistic regression analyses were performed to determine the association between serum albumin-corrected total calcium and magnesium levels and ruptured aneurysms.
Results: In multivariable analysis, both albumin-corrected calcium (odds ratio, 0.33; 95% confidence interval, 0.27-0.40) and magnesium (odds ratio, 0.40; 95% confidence interval, 0.28-0.55) were significantly and inversely associated with ruptured intracranial aneurysms.
Conclusions: In this large case-control study, hypocalcemia and hypomagnesemia at diagnosis were significantly associated with ruptured aneurysms. Impaired hemostasis caused by hypocalcemia and hypomagnesemia may explain this association.

Introduction: Dependent older adults in residential aged care are at increased risk of inadequate micronutrient intakes. Knowledge of dietary intakes in this group is needed to inform clinical decision making and guide nutrition policy and menu planning. This study aimed to determine the usual intake and food sources of micronutrients of New Zealand aged-care residents.

Background And Aims: Atrial fibrillation (AF) is a prevalent complication after cardiac surgery, worsening patient outcomes. Considering the established role of Ca2+-handling abnormalities in AF pathogenesis, this study aimed to evaluate if integrating cytosolic Ca2+-handling measurements with clinical risk factors enhances the risk prediction of post-operative AF.
Methods: Clinical data from 558 patients undergoing cardiac surgery without pre-existing AF from two centres were analysed.

Background: Sub-Saharan Africa is facing a dietary transition with both undernutrition and rising rates of non-communicable diseases. Adopting the reference diet proposed by the EAT-Lancet Commission can reduce both the environmental burden and improve health outcomes. However, whether this diet provides micronutrient adequacy in older adults in low-income settings has not been investigated.

Postoperative atrial fibrillation (POAF) is a common complication following anatomic lung resection, contributing to increased morbidity and mortality, prolonged hospital stays, and higher healthcare costs. Despite its frequency, there remains limited consensus on optimal pharmacologic management in this population, particularly in the context of balancing efficacy with the unique risks associated with thoracic surgery. This report aims to draw attention to the clinical significance of POAF in thoracic surgery, particularly following pulmonary resections, by presenting a representative case and contextualizing it through a focused review of current literature and consensus guidelines.

In this study, Cyprinus carpio nudus were exposed for 2 weeks to polyethylene microplastics (MPs) of two particle sizes (125 μm and 34 μm) at concentrations of 0, 40, 80, 160, 320, and 640 ppm. The experiment involved 11 treatment groups, each with triplicate tanks, and evaluated MPs accumulation in tissues, hematological profiles, plasma components, and antioxidant responses. Accumulation in the gill, intestine, and liver were quantified using Nile red staining and fluorescence microscopy, showing the highest accumulation in the intestine, followed by the gill and liver, with smaller MPs accumulated significantly more than larger MPs.
