Background: Vitamin D status has been associated with metabolic syndrome (MetSyn) and its components in different populations, but few studies have assessed this among Hispanics. The objective of this analysis was to assess such association in a clinic-based sample of Hispanic adults.
Methods: Medical records were reviewed retrospectively for the years 2005-2013. MetSyn was assessed using the revised NCEP-ATP III criteria. Vitamin D status was evaluated from reported serum 25(OH)D levels. A multivariable logistic regression model was used to assess the association between MetSyn risk and vitamin D status, controlling for important confounders.
Results: From 1379 medical records evaluated, 712 met the inclusion criteria. Most were females (62.6%), with a mean age of 53.8 ± 14.1 years, mean body mass index (BMI) of 30.1 ± 6.4 kg/m(2), and mean serum 25(OH)D levels of 24.4 ± 8.3 ng/mL. MetSyn was identified in 40.5% of the participants. Serum 25(OH)D levels in those with MetSyn (22.7 ± 8.0 ng/mL) were significantly lower compared to those without MetSyn (25.5 ± 8.4 ng/mL; P < 0.001). Serum 25(OH)D levels were inversely correlated to triglycerides, waist circumference, and fasting blood glucose (P < 0.05). In the multivariable logistic regression model, decreased serum 25(OH)D levels were associated with higher odds of MetSyn, even after adjusting for age, gender, BMI, and seasonality.
Conclusion: In this clinic-based sample, the odds of MetSyn increased as serum 25(OH)D levels decreased. These results have important public health implications for developing recommendations directed to increase vitamin D status in this sample.

The Role of Nutrition and Nutritional Supplements in the Prevention and Treatment of Malnutrition in Chronic Obstructive Pulmonary Disease: Current Approaches in Nutrition Therapy.
Curr Nutr Rep
January 2025
Faculty of Health Sciences, Department of Nutrition and Dietetics, Hacettepe University, Ankara, Turkey.
Purpose Of Review: Malnutrition is a significant comorbidity in Chronic Obstructive Pulmonary Disease (COPD), contributing to disease progression and reduced quality of life. This narrative review examines the role of nutritional therapy in the prevention and management of malnutrition in COPD, emphasizing evidence-based approaches and their clinical implications.
Recent Findings: COPD patients face increased metabolic demands, systemic inflammation, and reduced dietary intake, resulting in muscle wasting, sarcopenia, and cachexia.
Elevated serum vitamin B12 concentrations in a patient with pancreatic exocrine insufficiency.

This case describes a patient with pancreatic exocrine insufficiency and persistently elevated serum vitamin B12 concentrations that were not due to supplementation or associated with hepatic or hematological pathology. Laboratory investigations suggested the presence of macro-B12 as the cause of this patient's raised serum vitamin B12. Macro-B12 is often formed when vitamin B12-vitamin binding proteins (transcobalamin and haptocorrin) complex with immunoglobulins.

Background/objectives: Food-insecure individuals are at risk for poor health outcomes, including substandard sleep health. A possible association of food insecurity with sleep regularity has not been explored, and factors contributing to the relationship between food insecurity and sleep are not well understood. This cross-sectional study explored the relationship between food insecurity and sleep regularity and identified specific nutrients that mediated the association.

Maternal nutrition during pregnancy plays a pivotal role in influencing both maternal and fetal health, impacting neonatal anthropometric outcomes and long-term disease susceptibility. An advanced maternal age (AMA ≥ 35 years) has been linked to increased risks of obstetric complications and adverse neonatal outcomes, yet its specific nutritional profile remains underexplored. : This study aimed to evaluate the nutrient and polyphenol intakes of women at an AMA compared to those of a younger control group and to investigate associations with neonatal anthropometric measures.

Children and teenagers display a distinct metabolic dysfunction-associated steatohepatitis (MASH) phenotype, yet studies of childhood MASH are scarce and validated animal models lacking, limiting the development of treatments. Poor vitamin C (VitC) status may affect MASH progression and often co-occurs with high-fat diets and related metabolic imbalances. As a regulator of DNA methylation, poor VitC status may further contribute to MASH by regulating gene expression This study investigated guinea pigs-a species that, like humans, depends on vitC in the diet-as a model of pediatric MASH, examining the effects of poor VitC status on MASH hallmarks and global DNA methylation levels.
