The loss of a spouse is a highly stressful event that puts older adults at increased risk for morbidity and mortality. The risk is highest in the first year to 18 months post-loss; nevertheless, widow(er)s, in general, are at heightened risk of cardiovascular disease (CVD) related morbidity and mortality, and to a lesser extent, non-CVD related morbidity and mortality. The primary goal of this article is to argue for a perspective that considers diet and emotion-induced autonomic, neuroendocrine, and immune dysregulation, in unison, to understand the mechanisms underlying morbidity and mortality in early widowhood. Toward this end, we first summarize our previously published work, as well as work from other investigatory teams, showing that compared with those who were not bereaved, widow(er)s have higher levels of pro-inflammatory cytokine production and more dysregulated autonomic and neuroendocrine activity than non-widow(er)s, independent of health behaviors such as diet. We highlight that a major gap in our current understanding of the biobehavioral mechanisms that underlie the widowhood effect is the role of diet and hypothesize that the adverse health impact of grief and associated negative emotions and diet may be more than additive. Therefore, we propose that diet may be a pathway by which widow(er)s are at higher CVD risk requiring further investigation.

Background: The vital statistics in the third world countries are poor and have witnessed minimal improvement over the years with childhood mortality in Nigeria remaining one of the highest among the developing countries despite various child survival programmes. Child survival strategies can only be efficient if the major reasons for morbidity are known. The objective of this retrospective study was to review the patterns of childhood mortality at the emergency room of the Federal Teaching Hospital, Ido-Ekiti (FETHI).

Infective endocarditis carries a high risk of morbidity and mortality with recurrent infections and non-compliance. In the case of right-sided endocarditis, the indications for intervention are less clear. The Angiovac procedure provides a treatment for right-sided endocarditis that is a less-invasive and ideal for a complicated patient population.

Introduction: Arteriovenous (AV) fistula creation is the most common surgical procedure for providing vascular access for haemodialysis in patients with chronic kidney disease (CKD). The functioning of fistula dictates the quality of dialysis and the longevity of patients. The most common circumstances that require surgical takedown of AV fistula are thrombosis and rupture.

Introduction: Since the dawn of the new millennium, Candida species have been increasingly implicated as a cause of both healthcare-associated as well as opportunistic yeast infections, due to the widespread use of indwelling medical devices, total parenteral nutrition, systemic corticosteroids, cytotoxic chemotherapy, and broad-spectrum antibiotics. Candida tropicalis is a pathogenic Candida species associated with considerable morbidity, mortality, and drug resistance issues on a global scale.

Atrial arrhythmias, including atrial fibrillation (AF), are a major contributor to cardiovascular morbidity and mortality. Early detection and effective management are critical to mitigating adverse outcomes such as stroke, heart failure, and overall mortality. Wearable devices have emerged as promising tools for monitoring, detecting, and managing atrial arrhythmias near-continuously.
