Background: Neonatal Respiratory Distress Syndrome (RDS) is a dangerous disease in neonates and is accompanied by neonatal complications and death.
Objective: The aim of this study was the early determination of neonatal serum vitamin A levels as a possible novel predictor for neonatal RDS.
Patients And Methods: A case-control study with the identification number TCTR20210206001, was performed on 100 neonates who were admitted to the Neonatal Intensive Care Unit (NICU) of Tanta University Hospital (TUH) suffering from RDS (patient group) and 100 healthy neonates (control group). Estimation of serum vitamin A (retinol) was made for all neonates of this study within the first four hours after birth before any nutrition or therapies.
Results: The results showed no significant difference between serums retinol (RT) levels in grade 1 & 2 RDS neonates (patient group) and the serum RT levels in the control group, while there was a significant difference between serums retinol levels in grade 3 & 4 RDS neonates (patient group) and the serum retinol levels in the control group where the P-value was 0.006 and 0.002 respectively.
Conclusion: Serum vitamin A levels in neonates were found to be decreased in RDS neonates and could be used as a predictor for the development and severity of RDS.
Recommendation: It is recommended to carry out routine estimation of serum vitamin A levels in neonates as a novel predictor for neonatal RDS.

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.

Background: Vitamin D supplementation could offer irritable bowel syndrome (IBS) patients significant improvements in terms of symptom severity and overall quality of life (QoL). Yet, the potential benefits and risks associated with vitamin D supplementation still require additional investigation.
Objectives: We aimed to evaluate the impact of vitamin D supplementation on IBS using a systematic review and meta-analysis.

Purpose: The effect of exercise on serum concentration of vitamin D metabolites remains inconclusive, with studies reporting deviating results. This study evaluated the acute effect of a single session of two specific exercise forms; strength training (ST) and high-intensity interval training (HIIT), on circulating 25-hydroxyvitamin D (25(OH)D), free25(OH)D and 1,25-dihydroxyvitamin D (1,25(OH)2D), and skeletal muscle vitamin D receptor (VDR) gene expression, in healthy adults.
Methods: Thirty-nine participants (19 women and 20 men, age 21-30 years) completed a single bout of ST and HIIT exercise, separated by two weeks.

A fluorescence probe for "switch-on" detection of alkaline phosphatase (ALP) was developed based on Au nanoclusters anchored MnO nanosheets (Au NCs-MnO NSs), which were synthesized using bovine serum albumin (BSA) as template through a simple one-pot approach. In the sensing system, MnO NSs function as both energy acceptors and target identifiers, effectively quenches the fluorescence of Au NCs via fluorescence resonance energy transfer (FRET). The presence of ALP catalyzes the hydrolysis of L-ascorbic acid-2-phosphate (AAP) to ascorbic acid (AA), reducing MnO NSs to Mn and facilitate the fluorescence recovery of Au NCs.

Background/objectives: Vitamin K2 analogs are associated with decreased vascular calcification, which may provide protective benefits for individuals with coronary artery disease (CAD) by stimulating anti-calcific proteins like matrix Gla protein and adjusting innate immune responses. This study addresses a significant gap in understanding the association between serum levels of vitamin K2 analogs in different CAD types and examines their correlations with clinical risk parameters in CAD patients.
Methods: This case-control study enrolled CAD patients and healthy controls to assess and compare serum concentrations of two vitamin K2 analogs including menaquinone-4 (MK-4) and menaquinone-7 (MK-7) via ultra-performance liquid chromatography with tandem mass spectrometry (UPLC-MS/MS).
