Objective: Inflammation is one biological pathway through which marital dissolution and marital discord may increase risk for chronic disease. The present study was conducted to investigate the cross-sectional association between marital dissolution, marital discord, and C-reactive protein (CRP), an indicator of inflammation, in a probability sample of Irish adults aged 50 years or older.
Method: Data were drawn from The Irish Longitudinal Study on Ageing. Linear regression analyses were conducted to examine (a) the association between marital dissolution and CRP values (N = 2,545), (b) the association between marital discord and CRP values (N = 1,949), and (c) whether these associations were moderated by gender. Subsequent models adjusted for demographic characteristics and health variables.
Results: With respect to marital dissolution, individuals who were separated or divorced had significantly higher CRP relative to married individuals. With respect to marital discord, gender significantly moderated the association between marital discord and CRP, such that marital discord was significantly and positively associated with CRP for men, whereas this association was not statistically significant for women. Results for marital dissolution and marital discord remained statistically significant when adjusting for demographic characteristics and health variables.
Conclusions: This is one of the first studies to document a significant cross-sectional association between marital dissolution, marital discord, and CRP, incremental to demographic and health covariates, in a non-American probability sample. Results indicate that inflammation may be one pathway by which marital dissolution and marital discord contribute to risk for disease and early death.

Introduction: Self-harm represents a complex and multifaceted public health issue of global significance, exerting profound effects on individuals and communities alike. It involves intentional self-poisoning or self-injury with or without the motivation to die. Although self-harm is highly prevalent, limited research has focused on the patterns and trends of self-harm among hospital populations in low- and middle-income countries, particularly within Africa.

Background: Research has increasingly explored maternal resilience or protective factors that enable women to achieve healthier maternal and child outcomes. However, it has not adequately examined maternal resilience using a culturally-relevant, socio-ecological lens or how it may be influenced by early-life stressors and resources. The current study contributes to the literature on maternal resilience by qualitatively exploring the salient multi-level stressors and resources experienced over the lifecourse by predominantly low-income and minoritized women.

Background: Epilepsy, a neurological disorder characterized by recurrent seizures, presents considerable difficulties in treatment, particularly when dealing with drug-resistant cases. Dapsone, recognized for its anti-inflammatory properties, holds promise as a potential therapeutic option. However, its effectiveness in epilepsy requires further investigation.

The enzyme D-sorbitol dehydrogenase (SLDH) facilitates the conversion of D-sorbitol to L-sorbose. While current knowledge of this enzyme class predominantly centers on Gluconobacter oxydans, the catalytic properties of enzymes from alternative sources, particularly their substrate specificity and coenzyme dependency, remain ambiguous. In this investigation, we conducted BLASTp analysis and screened out a novel SLDH (Fpsldh) from Faunimonas pinastri A52C2.
