Objective: To provide information on the potential contribution to vitamin A nutrition in infants of strategies for improving maternal vitamin A status and increasing the consumption of breast milk.
Methods: The contribution of breastfeeding to the vitamin A nutrition of children in eight age groups between 0 and 24 months was simulated under four sets of conditions involving two levels of breast milk consumption with or without maternal vitamin A supplementation.
Findings: During the first 6 months, optimal breastfeeding on its own (compared with withholding colostrum and then partially breastfeeding after the first week) was as effective as postpartum maternal supplementation alone, retinol intakes being increased by 59 micrograms per day and 68 micrograms per day, respectively. Combined in synergy, these strategies increase retinol intake by 144 micrograms per day, or 36% of the recommended intake. After 6 months, partial breastfeeding continued to provide a significant proportion of the recommended intakes: 42% from 6-12 months and 61% during the second year.
Conclusion: Maternal supplementation with a high dose of vitamin A at the time of delivery and the promotion of optimal breastfeeding practices are highly effective strategies for improving vitamin A nutrition in infants and should be strengthened as key components of comprehensive child survival programmes.

This study explores the relationship between 25-hydroxyvitamin D/calcium/alkaline phosphatase (ALP) levels and kidney stone development via cross-sectional and Mendelian randomization (MR) analyses. We used data from the National Health and Nutrition Examination Survey (NHANES) 2013 to 2018 to explore the associations of 25(OH)D metabolite, calcium, and ALP levels with kidney stone development, LDSC analysis to determine the associations between their genetically predicted levels and kidney stone development, and MR analysis to determine the causality of those relationship via genome-wide association studies (GWASs). The cross-sectional study revealed a relationship between ALP levels and kidney stone development (Model 1: OR = 1.

Purpose: We sought to evaluate the relationship between blood vitamin A levels and myopia in adults aged ≥20 years in Korea.
Methods: We collected data of 15,899 participants aged ≥20 years from the Korean National Health and Nutrition Examination Survey. Participants underwent refraction tests to identify myopia and high myopia, and their blood pressure and obesity levels were measured.

The association between heavy metal exposure and diabetes is controversial and vitamin E (VE) may reduce diabetes risk. We aimed to examine the associations between blood heavy metals (BHMs) and diabetes risk and VE's role in the relationship. From the 2007-2018 NHANES, 10,721 participants aged ≥ 18 were included for multiple statistical analyses, which revealed that BHMs and dietary VE intake were negatively associated with diabetes and fasting plasma glucose (FPG).

Gallbladder mucocele, cholelithiasis, choledocholithiasis, and cholecystitis are significant contributors to morbidity and mortality in dogs. The exact etiology of these conditions remains poorly understood, though various factors, such as endocrinopathies, dyslipidemia, and impaired gallbladder motility, have been suggested as potential contributors. Surgical intervention has been described as the first choice of treatment when biliary rupture or obstruction is suspected; however, medical management may be an important part of therapeutic or preventative strategy.

Background: Millet peppers have rich and diverse germplasm resources. It is of great significance to characterize their phenotypes and physicochemical indicators.
Methods: 30 millet germplasms were selected to measure the fruit length and width, flesh thickness, number of ventricles, fruit stalk length, and single fruit weight, and the texture characteristics of fruit such as hardness, cohesiveness, springiness, gumminess, and chewiness were determined by a texture analyzer.
