Abstract
AIM Patients with type 2 diabetes (T2DM) often suffer from muscle cramps of varying severity. Studies have shown that muscle cramp is closely related to local microcirculation perfusion disorders. Diabetic retinopathy can not only reflect the microcirculation perfusion in the eye but also the systemic microcirculation in patients with diabetes. The aims of this study were to investigate the relationship between muscle cramps and diabetic retinopathy in patients with type 2 diabetes. METHODS A total of 150 adult patients with type 2 diabetes were enrolled and administered a questionnaire on muscle cramping, along with a visual analogue scale for pain. Diabetic retinopathy (DR) was determined by using fundus photography and graded as non-proliferative DR (NPDR) and proliferative DR (PDR). To assess whether there was an association between the muscle cramps and diabetic retinopathy, we conducted binomial logistic regression analysis. RESULTS Our study revealed that 48% of patients with T2DM experienced muscle cramps in the past three months. Patients self-reported suffering from muscle cramps exhibited a higher prevalence of DR (61% vs 38%, P < 0.05) and PDR (22% vs 4%, P < 0.05) compared with patients without muscle cramps. Serum 25-(OH) vitamin D, calcium, and magnesium levels were not significantly different between patients with and without muscle cramps. After adjusting for age, duration of diabetes, HbA1c, vitamin D, potassium, calcium, and magnesium, we demonstrated that diabetic retinopathy (OR, 2.18; 95% CI, 1.01-4.69; P< 0.05) and albumin (OR, 0.90; 95% CI, 0.82-1.00; P< 0.05) were highly associated with muscle cramps. Binomial logistic regression analysis also indicated that severity of DR is associated with muscle cramps. In addition, DR and PDR were found to be associated with muscle cramp frequency (P for trend < 0.05), duration (P for trend < 0.05), and pain severity (P for trend < 0.05). CONCLUSION Muscle cramps occur frequently in diabetes and are correlated with diabetic retinopathy and albumin. Patients with PDR exhibited a higher frequency, severity, and longer duration relative to those with NPDR or without DR. Our findings suggested that muscle cramps in individuals with T2DM might be a result of microvascular dysfunction. Modulation of microvascular perfusion might thus provide a therapeutic target for alleviating muscle cramps.

Abstract
Vitamin D deficiency (Vit D deficiency) is a global health concern and a common occurrence especially among pregnant women. It has been suggested that Vit D deficiency has implications on both the mother and the foetus. Vitamin D deficiency is the most under-diagnosed nutritional deficiency in the world, affecting the majority of individuals, irrespective of their geography, gender, age or race. Vitamin D deficiency is also linked with several diseases (autoimmune diseases, cancer, cardiovascular, dementia and musculoskeletal diseases). Therefore, appropriate supplementation is required in a deficient population. A diagnosis can be missed as symptoms associated with pregnancy are also seen in vitamin D-deficient women. A timely diagnosis and treatment can be beneficial as these disorders can cause maternal and foetal morbidity. Vitamin D status during pregnancy has been associated with maternal and foetal morbidity, but reported findings are inconsistent.
