(1) Several studies have suggested that the vitamin D receptor (VDR) gene plays a role in type 2 diabetes mellitus (T2DM) susceptibility. Nonetheless, the association between T2DM and VDR polymorphisms remains inconclusive. We determined the genotype of VDR rs1544410 (BsmI) and rs2228570 (FokI) polymorphisms among Malaysian patients with T2DM and their association with glycemic control factors (vitamin D levels, calcium, magnesium, and phosphate). (2) A total of 189 participants comprising 126 patients with T2DM (63 with good glycemic control and 63 with poor glycemic control) and 63 healthy controls were enrolled in this case-control study. All biochemical assays were measured using spectrophotometric analysis. VDR gene FokI and BsmI polymorphisms were analyzed using polymerase chain reaction and endonuclease digestion. (3) Our findings revealed no significant differences in VDR FokI and BsmI genotypes between participants with T2DM and healthy controls. Moreover, no significant association was observed between both single nucleotide polymorphisms and glycemic control factors. Participants with poor glycemic control had significantly lower serum magnesium levels and significantly higher HOMA-IR compared to the other groups. (4) The present study revealed that VDR gene BsmI and FokI polymorphisms were not significantly associated with T2DM.

Comparison of Vitamin D Levels, Bone Metabolic Marker Levels, and Bone Mineral Density among Patients with Thyroid Disease: A Cross-Sectional Study.

Diagnostics (Basel) 2020 Dec 11;10(12). Epub 2020 Dec 11.

Endocrine Unit, Department of Medicine, School of Medical Sciences, Universiti Sains Malaysia Health Campus, Kubang Kerian 16150, Kelantan, Malaysia.

Thyroid hormones have a catabolic effect on bone homeostasis. Hence, this study aimed to evaluate serum vitamin D, calcium, and phosphate and bone marker levels and bone mineral density (BMD) among patients with different thyroid diseases. This cross-sectional study included patients with underlying thyroid diseases ( = 64, hyperthyroid; = 53 euthyroid; = 18, hypothyroid) and healthy controls ( = 64). BMD was assessed using z-score and left hip and lumbar bone density (g/cm). The results showed that the mean serum vitamin D Levels of all groups was low (<50 nmol/L). Thyroid patients had higher serum vitamin D levels than healthy controls. All groups had normal serum calcium and phosphate levels. The carboxy terminal collagen crosslink and procollagen type I N-terminal propeptide levels were high in hyperthyroid patients and low in hypothyroid patients. The z-score for hip and spine did not significantly differ between thyroid patients and control groups. The hip bone density was remarkably low in the hyperthyroid group. In conclusion, this study showed no correlation between serum 25(OH)D levels and thyroid diseases. The bone markers showed a difference between thyroid groups with no significant difference in BMD.

A real-world study in patients with type 2 diabetes mellitus treated with gliclazide modified-release during fasting: DIA-RAMADAN.

Diabetes Res Clin Pract 2020 May 21;163:108154. Epub 2020 Apr 21.

Dasman Diabetes Institute, Kuwait City, Kuwait.

Aims: To explore the real-world safety and effectiveness of gliclazide modified release (MR) in patients with type 2 diabetes mellitus (T2DM) fasting during Ramadan.

Methods: DIA-RAMADAN (NCT04132934) was a prospective, international, observational study conducted in nine countries. Patients >18 years of age with T2DM (N = 1244) were examined at an inclusion visit (V0) occurring 6-8 weeks before the start of Ramadan. Patients received a diary to report treatment changes, hypoglycaemic events (HEs), and other adverse events. Gliclazide MR was taken once daily for 14-18 weeks. A second visit (V1) was conducted 4-6 weeks after the end of Ramadan. The primary endpoint was the proportion of patients reporting ≥1 symptomatic HE. Changes in HbA, fasting plasma glucose (FPG), and body weight were secondary endpoints.

Results: The proportion of patients reporting ≥1 symptomatic HE during Ramadan was low (2.2%) with no reported severe HEs. There was a significant reduction in HbA (-0.3%), FPG (-9.7 mg/dL), body weight (-0.5 kg) and body mass index (-0.2 kg/m) between V0 and V1 (p < 0.001).

Conclusions: Patients with T2DM treated with gliclazide MR during Ramadan have a low risk of hypoglycaemia and maintain glycaemic control and weight while fasting.

Fasting experience of patients with Type 2 diabetes mellitus on insulin therapy during Ramadan: VISION Ramadan substudy.

Diabetes Res Clin Pract 2019 May 27;151:285-289. Epub 2019 Feb 27.

Eli Lilly and Company, Gurgaon, India.

Aims: To describe the characteristics and fasting experience of a subgroup of patients in the VISION study who initiated insulin therapy and chose to fast during Ramadan, and to discuss the VISION Ramadan substudy data in the context of previous Ramadan studies.

Methods: The VISION study was a prospective, non-interventional, observational study of adult patients with Type 2 diabetes mellitus in 6 countries in the Western Pacific, Middle East and North Africa, receiving insulin injection therapy for the first time. In this VISION Ramadan substudy, fasting data was collected during Ramadan 2014 and 2015.

Results: Of 1617 patients in the VISION study, data was collected for 357 patients who chose to fast during Ramadan. At baseline, mean HbA1c was 10.1%, duration of diabetes was 8.8 years, and mean BMI was 30 kg/m. All patients with non-missing data (n = 169) received advice on fasting during Ramadan. The majority of patients fasted for the full month of Ramadan, and around one-third of patients fasted outside Ramadan.

Conclusions: Here we provide an update on the characteristics and Ramadan experience of patients with Type 2 diabetes mellitus who initiated insulin therapy and chose to fast during Ramadan. There is still a need to explore patient's experience during fasting, and identify and address methods to better help manage those patients.

Understanding Dieting and Previous Weight Loss Attempts among Overweight and Obese Participants: Insights into My Body Is Fit and Fabulous at Work Program.

Korean J Fam Med 2018 Jan 23;39(1):15-22. Epub 2018 Jan 23.

Program of Nutrition and Dietetics, School of Health Sciences, Universiti Sains Malaysia, Kelantan, Malaysia.

Background: A qualitative study providing an in-depth exploration of people's view and the increasing burden of overweight and obesity is required. This study aimed to explore the understanding of dieting and previous experiences on weight loss attempts among overweight and obese government employees in Kelantan, Malaysia, prior to recruitment into the intervention program.

Methods: Thirteen focus group discussions involving 129 participants from a weight-loss intervention program were conducted within the first 1 month of recruitment. These discussions were moderated by two trained researchers in the Malay language and assisted by an interview guide. They were audio-recorded and transcribed verbatim. A thematic analysis was performed, and codes and themes from each discussion were constructed.

Results: The participants understood dieting with various meanings, including skipping meals and removing rice from daily diets. They applied numerous methods to lose weight and achieved various outcomes. Health and appearance, social support, and compliance with current trends were the factors motivating these participants to lose weight. Their determination to lose weight was limited by lack of self-control and motivation, experiences of unpleasant effects, influence on weight, and environmental and health factors.

Conclusion: Real-life weight loss experiences and perceptions provided relevant insights into current weight loss management strategies. Some of these issues and misunderstandings should be emphasized in weight loss strategies during health promotion.
