This study is a retrospective-prospective cohort study that investigates the factors influencing neonatal umbilical cord blood 25(OH)D levels, and the impact of exposure to low intrauterine 25(OH)D levels on neonatal prognosis. Newborns born in Sun Yat-sen Memorial Hospital of Sun Yat-sen University from August 2023 to August 2024 were selected. 2ml of umbilical cord blood was collected to test serum 25(OH)D levels. Based on the umbilical cord blood 25(OH)D levels, newborns were divided into three groups: vitamin D deficiency (<30nmol/L), insufficiency (30~50nmol/L), and sufficiency (>50~250nmol/L). Factors influencing neonatal vitamin D levels at birth were investigated by reviewing medical records, questionnaire collection, phone interviews, etc., collecting data on basic neonatal information, maternal information, complications during pregnancy, prenatal biochemical test results, medication history during pregnancy, lifestyle habits during pregnancy, and vitamin D supplementation status. Phone follow-ups on the health of the newborns during their hospital stay and at 1 month and 2 months after discharge were conducted to investigate the impact of exposure to low intrauterine 25(OH)D levels on neonatal prognosis, providing a theoretical basis for early intervention in high-risk pregnant women and early identification of high-risk groups with vitamin D deficiency or insufficiency among newborns. Miscarriages prevention is a major feature of our hospital's obstetrics department. Many pregnant women who are hospitalized and give birth at our hospital have a history of fetus protection. Choosing pregnant women and newborns from our hospital's obstetrics department as research subjects is conducive to exploring the impact of specific diseases and medication histories on neonatal vitamin D deficiency, which is an innovative aspect of this study.
This study is an experimental design study in which demographic characteristics, food consumption, biochemical parameters and anthropometric measurements of individuals with low vitamin D levels before and after consuming UV-enriched foods will be examined.
This is double-blind, controlled fiel trial, to compare fortified egg with D3-or 25(OH)D3 and non-fortified eggs in healthy preschool-age children 12 to 60 months of age, affiliated to day-care centers at Secretaria de Desarrollo Social (SEDESOL). The study aims to answer are: 1. to evaluate the efficacy of fortified egg with vitamian D3 on serum concentrations of 25-hydroxyvitamin D3 2. and to evaluate parathyroid hormone (PTH) in children aged 12 to 60 months of age. - Children would be given for breakfast fortified egg/non-foritfied egg three times per week for 12 weeks. - Blood samples will be taken at baseline and at the end of study. - Anthropometric meassurements weight /height will be taken at baseline and at end of study.
The aim of this study is to perform a double-blind, randomised, dose-response trial of vitamin D3 supplementation in United Kingdom (UK)-dwelling adults of white European, South Asian, and black African/Caribbean ethnicity to investigate the distribution of dietary intakes needed to maintain adequate vitamin D status in winter, as indicated by serum 25(OH)D concentrations at ranges of >25 to 50 nmol/L. In addition, this study will investigate the effect of vitamin D3 supplementation on immune health, muscular strength, and overall health.
This study is a randomized controlled trial which compares the effect of vitamin D3 therapy 5,000 IU daily and 50,000 IU on 25(OH)D and 1,25(OH)2D, VDBP, and 24,25(OH)2D maternal serum levels in pregnant women with vitamin D deficient and insufficient.
To investigate the role of Vitamin D (VD) deficiency as a risk factor for the development and malignant transformation of Oral lichen planus (OLP) taking into consideration sex, dietary habits, sun exposure, socioeconomic status and psychological factors.
The observational study is to compare vitamin D deficiency and related indicators among different spontaneous abortions in describe female reproductive health.The main question aim to answer is: the possible pathogenesis of recurrent spontaneous abortion caused by vitamin D. Participants, who visit the RSA specialty clinic, will provide medical history information, regularly exam based on the condition, following up on pregnancy status.Participants will be asked to supply vitamin D preparation and do moderate exercise outdoors, comparing the effect after treatment.
Patients aged between 18-65 who visit the Physical Medicine and Rehabilitation outpatient clinic diagnosed with Bell Palsy will be included in the study. The patients' Bell Palsy grade will be evaluated by Houseman Brahman (HB) Scale and their disability level will be evaluated by Facial Disability Index (FDI). Their serum vitamin D level will be noted. The patients having vitamin D deficiency will be randomized into two groups. Group 1 will be given 50.000 IU/week vitamin D replacement for 8 weeks. All the patients will be included in a standard physical therapy and home exercise program. Both groups will be asked for a control visit at weeks 8.Their clinical recovery will be evaluated by HB staging and FDI by the Physical Medicine and Rehabilitation specialist who is blind to the randomization.
Osteoarthritis (OA) knee is one of the commonest chronic degenerative conditions. It causes disability in elderlies due to pain and stiffness. The prevalence of radiologic knee osteoarthritis increases in proportion to age, reaching an astounding 64.1% for patients who are over 60 years of age. In 2021, there were over 26,000 patients on the Hospital Authority (HA) waiting list for knee total knee replacement (TKR) and with only 4300 TKRs performed, the nominal waiting time for TKR was almost 89 months. Low vitamin D can adversely affect cartilage thickness and study suggested that low serum vitamin D is associated with increased radiographic knee OA progression. A systematic review concluded that vitamin D supplements can improve pain and function in patients with knee OA. Vitamin D has long been recognized for its effect on musculoskeletal health and increasing attention has been focused for its effect on muscle function. Vitamin D have a direct effect on muscle hypertrophy by acting on specific vitamin D receptors (VDRs) on myocytes, and sufficient levels of vitamin D in patients have been found to correlate with an increase in the size, number, and strength of muscle fibres. Vitamin D also seems to exert beneficial effects by its interplay with myokines such as myostatin and irisin. One study also showed that muscle nuclear VDR was increased by 30% and augmented muscle fibre size by 10% in elderly females (mean age of 78 years) taking vitamin D orally at a rate of 100 µg/day (4000 IU/day) for 4 months. This will be a double-blinded RCT investigating the effect of vitamin D supplements or knee muscle strength, physical function, pain symptoms and, sarcopenia status. The study will be a follow-up study with assessment at baseline, 3- ,6-and 12-months post vitamin D intervention.
