Objective: High prevalence of hypovitaminosis D has been reported to be common in different regions of the Middle East. The objective of the present study was to examine the predictors of vitamin D deficiency and insufficiency in Bahrainis.
Design: A cross-sectional study.
Setting: Blood transfusion volunteers at a blood bank.
Subjects: Serum levels of total 25-hydroxyvitamin D, bone markers and other parameters such age, sex, season and clothing style in the 500 healthy Bahrainis were investigated.
Results: In the entire cohort the prevalence of vitamin D deficiency was 49.4% and the relative risk of vitamin D deficiency increased significantly by 1.1, 1.2, 1.5, 1.7 and 1.2 fold with younger age group (P = 0.03), hyperparathyroidism (P = 0.01), low serum Ca (P < 0.001), warm and hot months of the year (P < 0.0001) and female sex (P = 0.002), respectively. In females the prevalence of vitamin D deficiency was 67.6% and the relative risk of vitamin D deficiency increased significantly by 1.1, 1.2, 1.2, 1.2 and 1.4 fold with younger age group (P = 0.04), hyperparathyroidism (P = 0.03), low serum Ca (P = 0.001), warm and hot months of the year (P = 0.001) and conservative clothing style (P = 0.04), respectively. In contrast, in males the prevalence of vitamin D deficiency was 31.2% and the relative risk of vitamin D deficiency was increased by 1.6 fold in warm and hot months of the year (P < 0.0001).
Conclusions: High prevalence of low circulating levels of vitamin D and the relative risk factors associated with vitamin D deficiency and insufficiency observed in the present study suggest an urgent need for public health interventions including vitamin D food fortification in Bahrain.

Background: Vitamin D is thought to play a role in the development of migraine, but the nature of the relationship is still not fully understood. Although some studies have shown an association between vitamin D deficiency and migraine, other studies have had inconsistent or inconclusive results. Therefore, further research is needed to better understand the relationship between vitamin D and migraine headaches.

Autosomal recessive hypophosphatemic rickets type 2 (ARHR2) is an uncommon hereditary form of rickets characterised by chronic renal phosphate loss and impaired bone mineralisation. This results from compound heterozygous or homozygous pathogenic variants in ectonucleotide pyrophosphatase/phosphodiesterase 1 (ENPP1), a key producer of extracellular inorganic pyrophosphate (PPi) and an inhibitor of fibroblast growth factor23 (FGF23). ENPP1 deficiency impacts FGF23 and increases its activity.

Background: Diagnosis of Alzheimer's disease (AD) via MRI is costly and can be limited by regional availability. With the recent advancements and discovery of amyloid in the retina, diagnosis of AD and the effect of AD pathology on the retina is becoming well characterized. However, the prevalence of vascular contributions to cognitive impairment and dementia (VCID) and its effects on the retina are less well known.

Background: Brain endothelial cell (EC) stress, including that induced by vascular amyloid β (Aβ) deposits in cerebral amyloid angiopathy (CAA) and Alzheimer's disease (AD), contributes to cerebral blood flow impairment, blood brain barrier (BBB) damage, neurovascular unit dysfunction, microhemorrhages and hypoperfusion, precipitating neurodegeneration and neuroinflammation processes. Epidemiological and experimental evidence suggests that hyperhomocysteinemia (Hhcy) contributes to increasing AD risk as well as CAA pathology. However, the cellular and molecular mechanisms through which Aβ and Hhcy drive EC and BBB dysfunction, whether the molecular effects of these challenges are additive or independent, and possible therapeutic strategies, remain to be determined.
