Individual variations in the active form of vitamin D (Vit.D) arise from a combination of dietary intake, sun exposure, and genetic factors, making it complex and challenging to maintain optimal levels. Among Vit.D-related genes, variations in and influence Vit.D synthesis, regulates its inactivation, and the Vit.D receptor (VDR) mediates Vit.D signaling. These genetic variations contribute to substantial differences in Vit.D concentrations and associated clinical effects. However, there has been a lack of comprehensive, simultaneous exploration of these key genes and their clinical implications. This review provides a systematic analysis of genetic variants in Vit.D-related P450 genes identified in human clinical studies, along with in silico predictions of their functional consequences. Since multiple genes seem to influence the body's response to Vit.D, studying just one genetic variant may not fully explain Vit.D deficiency. A comprehensive evaluation of all Vit.D-related genes could offer valuable insights for advancing personalized medicine in Vit.D management. This study provides a foundation for developing a more personalized approach to Vit.D supplementation and regulation, guided by genetic information.

Introduction: The relationship between Vitamin D (VitD) levels and cognitive function in young adults remains unclear, with conflicting results in existing literature. This study aimed to assess the prevalence of VitD deficiency and mild cognitive impairment (MCI) and to explore the correlation between serum VitD levels and cognitive functions in young indigenous adults in Meghalaya.
Methods: A hospital-based cross-sectional study was conducted in a tertiary care centre in Shillong, Meghalaya, involving 137 healthy young individuals associated with the centre.

Background: Celiac disease (CeD) is an autoimmune disorder, causing significant gastrointestinal (GI) and non-GI symptoms. The only effective treatment is a gluten-free diet (GFD), but adherence can be challenging. This study investigates GFD adherence among CeD patients and the change in their clinical and pathological conditions over time.

Purpose: To investigate the correlation between serum Wnt1-inducible signalling pathway protein-1 (WISP-1) levels and cerebral infarction (CI) in patients with type 2 diabetes (T2DM).
Methods: This was a cross-sectional study. We enrolled 87 patients with T2DM (T2DM group) and 83 T2DM patients with cerebral infarction (DCI group) who were admitted to the First Affiliated Hospital of Soochow University.

: Gentamicin is one of the most effective and widely used antibiotics to treat serious infections. In addition to its bactericidal properties, gentamicin has a nephrotoxic effect that results in acute kidney injury (AKI). AKI may be intensified by hypovitaminosis D.

Background: Vitamin D (VitD) plays an important role in immune modulation. VitD deficiency is associated with increased susceptibility to acute respiratory syndrome as observed in COVID-19. We evaluated potential associations between serum VitD levels and risk of COVID-19 infection and hospitalisation, within the overall and cancer populations.
