Filter by:The purpose of this study, is to determine whether daily supplements of vitamin D improves wound healing in diabetic patients with chronic foot ulcers.
The efficiency of different vitamin D formulations in treating suboptimal vitamin D status in adult population will be determined. It will provide insights into the influence of formulation on vitamin D absorption. A randomised controlled intervention trial will be conducted on at least 72 subjects (18-65 years) with suboptimal Vitamin D status. Subjects will be selected from a pool of subjects in Part 1 of the study, after completion of winter sampling. Study subjects will be randomised into four study groups (at least 18 subjects per study group). Three different treatments will be compared with a control group, which will not receive any supplemental Vitamin D. The three tested Vitamin D preparations in the treatment groups will be (A) oil-based VALENS vitamin D; (B) water-based VALENS vitamin D; and (C) Vitamin D capsules with starch-adsorbed vitamin D (powder). All these products are commercially available. Prior to study, actual level of vitamin D will be determined using appropriate analytical method. The treatment will be with 1000 IU Vitamin D per day, for two months, in all three groups. Second serum vitamin D level will be determined on last day of the treatment, and compared with pre-treatment vitamin D level.
The aim of this study is to investigate the safety and metabolic-hormonal efficiency of supplementation vitamin D deficient/insufficient PCOS women with (calcium +vitamin D + metformin) for 8 weeks compared to (placebo+ metformin).
This study investigates the influence of different food matrices on the bioavailability of vitamin D. Although most vitamin D comes from skin synthesis in response to sun exposure, dietary intake is also important - especially during winter time where there is no endogenous production of vitamin D in Denmark. A way to maintain an adequate vitamin D status is to supplement either as tablets/droplets or as fortified food. However, there seems to be an inter-individual variation in response to supplementation. This study aims to investigate whether this variation in absorption of vitamin D may depend on delivery system.
Previous studies have shown that improving vitamin D status among the elderly may lead to an improvement in some inflammatory markers, especially with patients with type 2 diabetes. The aim of our trial is study the effect of vitamin D supplementation on inflammatory markers in patients having type 2 diabetes.
Title:Impact of vitamin D administration on cardiac autonomic tone in Asthma Chronic Obstructive Pulmonary Disease (COPD) Overlap patients: A blinded randomized control trial. Background: Respiratory disease is closely associated with cardiovascular disease. Reduced Heart Rate Variability (HRV), reflecting impaired autonomic activity have been reported in both asthma and COPD. Vitamin D deficiency is a common feature in Asthma COPD Overlap (ACO) patient. Relationship between vitamin D deficiency and low HRV has been reported. Vitamin D administration has been reported to improve cardiac autonomic modulation in healthy subjects in response to external stressor. Objective: To assess the changes in cardiac autonomic tone after vitamin D administration for 90 days in vitamin D deficient ACO patients. Hypothesis:Null: Vitamin D administration does not have impact on cardiac autonomic tone in vitamin D3 deficient ACO patient. .Method: This randomized controlled trial will be conducted by Department of Physiology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Shahbag, Dhaka from September' 2017 to August' 2018. For this study, a total number of 60 subjects (age > 40 years, both male and female) will be randomly selected. 30 diagnosed vitamin D deficient Asthma COPD Overlap (ACO) patients will form group A and another 30 diagnosed vitamin D3 deficient ACO patients with similar age, sex, (Body Mass Index) BMI will constitute control group B. Patients of study group B0 will take vitamin D3 with a prescribed schedule for 3 months and followed up after 3 months (group B90). On the other hand patients of group A1 will be given placebo and followed up after 3 months (group A90). All these patients will continue their medication prescribed by physician during these 3 months. On the basis of data recording - group B1 and group B90 will constitute pre and post vitamin D group whereas group A0 and group A90 will represent pre and post placebo follow up at day 0 and day 90. Cardiac autonomic nerve function will be assessed by recording ECG & Heart Rate Variability (HRV) analysis by a data acquisition device, powerlab 8/35, AD instruments, Australia. HRV measures of all patients will be recorded at baseline.Then after 3 months of follow up it will be recorded in both groups at day 90. Serum 25(OH)D level will be measured of all subject at day 0 and day 90. For statistical analysis unpaired and paired "t" test will be done by using Microsoft Office Excel Word version 2016
The Combined effect of Vitamin D3 and Omega-3 supplements on serum leptin and Glycated hemoglobin (Hb A1C) levels in Jordanian people with vitamin D deficiency.
Background/aim: Investigators aimed to investigate the effect of D vitamin levels on Sugammadex and Neostigmine reverse durations in the study. Materials and methods: Eighty patients between 18 and 65 years, with ASA I-III status who were undergoing surgery under general anaesthesia were included the study. All patients were randomly divided into two groups with double blindness and 1.25 (OH) 2 vitamin D, 25 (OH) 2 vitamin D, and calcium levels were measured. At the end of the operation, 2 mg/kg of Sugammadex was administered to one group and Atropine + Neostigmine to the other group. The patients were also divided into two groups as to whether their vitamin D levels were ≥ 30 ng/mL or below. A train of four values was recorded after a hypnotic agent was given at the beginning and throughout the operation. The time to complete the disappearance of response to TOF stimulation was recorded as T0. End of the operation: When 2 responses to TOF stimulation were taken, the following times were recorded until the extubation phase by administering at least 2 mg/kg of Sugammadex or 0.05 mg/kg of Neostigmine 0.05 mg/kg of Atropine per kg of body weight. The time until the TOF value reached 50,70,90% and extubation were recorded.
- Vitamin D considers as the most potent effect on calcium level in blood it was found that vitamin D target mainly bone tissue intestine and kidney for calcium absorption In bone, vitamin D stimulates mainly the activity of osteoclasts osteoblast activity on the other hand it increases the production of extracellular matrix proteins by different osteoblastic activity. Vitamin D also increase intestinal calcium absorption and regulate synthesis and secretion of parathyroid hormone (PTH) Implant consider as one of the most successful treatment modalities that usually used in dental clinics for restoring single or multiple missed teeth knowing that successful rate of dental implant may reach up to 99% however there are many different techniques for implant placement they mainly depend on the same procedure for implant placement even sequential drilling technique or single drilling technique some paper supported that sequential drilling is much better than single drilling technique on other hand some assume that single drilling is much better as it save time effort material less bone trauma & less heat generation although there are many studies performed on sequential drilling & single drilling techniques we still have a gap for understanding the ideal technique for implant placement in patients with vitamin D deficiency
The overall objective of the study is to determine the pharmacokinetics of Vitamin D supplementation in children who have asthma and are overweight or obese.
