Vitamin D deficiency is prevalent across all geographic areas, age groups, and seasons and is increasing in incidence. Vitamin D receptors have been found to be present in almost every body cell and tissue. Clinical research has alluded to a preventive effect of vitamin D supplementation on cardiovascular disorders such as myocardial infarction, hypertension, and dyslipidemia. Furthermore, a low serum vitamin D level has been associated with an increased risk for cardiovascular disease. This article examines the association between serum vitamin D levels and cardiovascular disease mortality and risk.

Background: Vitamin D deficiency is widely prevalent throughout the world. Pregnant women, neonates and infants form most vulnerable groups for vitamin D deficiency. Hypovitaminosis D in pregnancy has been reported to cause various fetomaternal effect, i.e. increased risk of preeclampsia (PE), gestational diabetes mellitus (GDM), caesarean section, hypocalcemia, subclinical myopathy, neonatal tetany, hyperbilirubinemia congenital rickets and infantile rickets, etc. Only few Indian studies are available in this regard. The objectives are to find prevalence of vitamin D deficiency in pregnant women and to evaluate the effect of supplementation with cholecalciferol in improving vitamin D levels in pregnant women and evaluate its correlation with feto-maternal outcome.Methods: A prospective observational was conducted on 120 Pregnant women on their first visit to hospital irrespective of gestational age were offered the test and on the basis of inclusion and exclusion criteria are included in study and vitamin D level was done to know the prevalence of vitamin D deficiency. Apart from routine obstetrical investigation, serum vitamin D (total) level was estimated. All results were recorded and analyzed statically.Results: Out of 120 patients 101 (84.1%) were found to be vitamin D deficient. Mean age of vitamin D deficient group was 28.31±3.86 and sufficient group was 26.37±2.83.81 (67.5%) were vegetarian and 39 (32.5%) were nonvegetarian.75 (92.59%) vegetarian and 26 (66.66%) non-vegetarian found to be vitamin D deficient. (p<0.05). Vitamin D supplementation has been observed to reduce risk of preeclampsia. (p<0.05) and vitamin D sufficiency associated with reduced risk of low birth weight babies.Conclusions: Vitamin D supplementation reduces risk of maternal comorbidities and helps improve neonatal outcomes.

Background: Cardiovascular disease (CVD) is a main cause of mortality and disability worldwide. One of the key factors in the soaring prevalence of CVD globally has been nutrition transitions and changes in dietary patterns. Objective: This study investigated the association between two diet scores, namely, a high-fat dietary (HFD) pattern score and a Mediterranean diet (MedDiet) score, and CVD risk factors (obesity, hypertension, total cholesterol, and blood glucose) and serum 25 hydroxy vitamin D (25[OH]D) levels. Methods: Three hundred twenty-one participants were included in this study. Fasting blood tests were collected from all participants for biochemical measurements. Blood pressure and anthropometric measurements were also taken. A validated, semi-quantitative food frequency questionnaire was used to collect data on participants’ dietary intake. Dietary scores for the HFD pattern were calculated based on recommended food groups. MedDiet scores were calculated based on a previously validated method that contains 14 questions related to MedDiet. Both diet scores were classified into tertiles. Linear regression analyses were performed to assess the statistical significance of the tertile groups. Result: A significant association was found between HFD score and obesity when comparing the lowest tertile (27.3±4.6 kg/m2) of HFD scores with the medium tertile (29.2±5.7 kg/m2; P = 0.02). A higher HFD score was significantly associated with lower 25(OH)D levels (P = 0.02). In addition, a significant association was observed between MedDiet scores and 25(OH)D levels, with an increase in MedDiet score resulting in an increase in 25(OH)D levels (P = 0.01). Furthermore, a significant negative association between MedDiet scores and low-density lipoprotein levels was reported only in participants with CVD (P = 0.03). Conclusion: The results of this study revealed that HFD and MedDiet scores might have a role in the development of CVD and vitamin D deficiency among the Saudi Arabian population. Further studies are required using diet scores to assess the quality of dietary patterns and their association with an increased risk of diseases in Saudi Arabians.

Background: Transient tachypnea of newborn (TTN) is a common cause of respiratory distress in newborns with estimated incidence of 1-2% of all newborns. Although a self-limiting transient condition but it may cause severe morbidities. This study was conducted to find association of serum vitamin D levels in neonates who develop TTN as compared to normal healthy neonates.Methods: With thorough history with structured questionnaire and lab tests, serum vitamin D levels of 45 neonates who develop TTN were compared with 56 healthy neonates in control group.Results: Out of 45 neonates who develop TTN 39(86.7%) were deficient in vitamin D as compared to control group where 33(58.9%) out of 56 healthy neonates were deficient in vitamin D.Conclusions: Lower vitamin D levels at birth in term neonates is associated with increased risk of developing TTN and vitamin D may have a role in its pathogenesis.

Abstract Sarcopenia is an age-related disease with an increased risk of mortality. It is emerging that low serum vitamin D (25(OH)D) affects the sarcopenic state in general, but in rheumatoid arthritis (RA), these associations are not understood although the prevalence of vitamin D insufficiency is high in RA. We conducted a cross-sectional study of older female outpatients from our cohort (KURAMA) database. We measured skeletal muscle mass, handgrip strength, and gait-speed to diagnose severe sarcopenia. The serum 25(OH)D concentration was measured using electrochemiluminescence immunoassay. A total of 156 Patients (sarcopenia:44.9%, severe sarcopenia: 29.5%, and without sarcopenia: 25.6%) were enrolled. Classification of vitamin D status at a cutoff point of median 25(OH)D concentration revealed that low 25(OH)D status was associated with a high prevalence of severe sarcopenia and with low measured values of muscle mass, handgrip, and gait-speed. Furthermore, multiple regression analysis identified that low 25(OH)D status was associated with a high prevalence of severe sarcopenia (OR 6.00; 95% CI 1.99–18.08). In components of sarcopenia, both low physical performance and muscle mass were associated with low 25(OH) status. In conclusion, vitamin D levels are associated with severe sarcopenia and its components, and modification of vitamin D status including vitamin D supplementation may play a role in improving sarcopenia in RA.

Abstract BackgroundAccumulating data have highlighted the prominence of supplementation as an effective approach for vitamin D deficiency. But individuals vary in their response to vitamin D supplementation. In this study, the effect of cardiometabolic risk factors were evaluate on magnitude of response to vitamin D supplementation by using novel statistical analysis, artificial neural networks(ANNs).Methods608 participants aged between 12 to 19 years old were assed in this prospective interventional study. Nine vitamin D capsules containing 50000IU vitamin D/weekly were given to all participants over the 9 week period. The change in serum 25(OH)D level was calculated as the difference between post-supplementation and basal levels. Suitable ANNs model were selected between different algorithms in the hidden and output layers and different numbers of neurons in the hidden layer. Then, the major determinants in predicting response to vitamin D supplementations were identified (Trial registration: IRCT201509047117N7; 2015-11-25; Retrospectively registered)ResultsSigmoid in both hidden and output layers with 4 hidden neurons had acceptable sensitivity, specificity and accuracy area under the ROC curve in our study. Baseline serum vitamin D (30.4%), waist to hip ratio (10.5%), BMI (10.5%), systolic blood pressure (8%), heart rate (6.4%), and waist circumference (6.1%) were the greatest importance in predicting the response in serum vitamin D levels. ConclusionWe provide the first attempt to relate anthropometric specific recommendations to attain serum vitamin D targets. With the exception of cardiometabolic risk factor, the relative importance of other factors and the mechanisms by which these factors may affect the response requires further analysis in future studies.

Abstract Background Vitamin D is a critical factor in bone remodelling, calcium absorption and may promote anti-inflammatory cytokines in the gut. Inflammatory bowel disease (IBD) is associated with a reduction in serum Vitamin D levels and a chronic inflammatory state, both of which are strong risk factors for bone density loss affecting IBD patients. Despite European and North American IBD maintenance guidelines for Vitamin D monitoring and bone density scans, there are limited North American investigations into factors influencing serum Vitamin D levels in the IBD patient population specifically. Aims We investigated whether patient demographics, disease severity indexes and/or inflammatory markers were linked to low serum Vitamin D levels in our IBD patients. We also established the extent of Vitamin D serum deficiencies and supplementation rates in our IBD patients. Methods A retrospective chart review of a single clinician’s practice at London Health Science Centre, Victoria Hospital, over the past 20 months, was performed to: 1) assess the frequency of low serum 25-OH Vitamin D (25-OH D) in the IBD patient population and 2) determine whether patient disease severity was linked to lower 25-OH D levels. A multivariate regression analysis was performed assessing Crohn’s Disease (CD) or Ulcerative Colitis (UC) patient factors: age, sex, disease duration, seasonality, current pharmacologic treatments, past surgeries, CD Activity Index, UC Mayo score, C-reactive protein, and fecal calprotectin (Fcal) level. Results 175 IBD patients had at least one 25-OH D measurement with 71 patients actively on Vitamin D therapy. Of UC and CD patients who were not on Vitamin D therapy, 63% (17/27) and 79% (61/77) were 25-OH D deficient, respectively. 25-OH D levels in the CD population was associated with Vitamin D supplementation (regression coefficient [RC] 23.99, 95% confidence interval [CI] 14.54 to 33.45), summer season ([RC] 9.90, [CI] 0.56 to 19.24), and past bowel resection ([RC] -10.61, [CI] -20.48 to -0.76). 25-OH D levels in the UC population was associated with Vitamin D supplementation (regression coefficient [RC] 47.23, 95% confidence interval [CI] 27.62 to 66.83), and Mayo severity scores ([RC] -23.01, [CI] -41.82 to -4.20). Fcal (78 patients) was inversely associated with 25-OH D levels but the trend was not significant. Conclusions Overall, 25-OH D levels were lower in both the UC and CD patient populations relative to the already deficient Canadian population. However, IBD patients are responsive to Vitamin D supplementation. Tools with more objective evidence of disease severity such as UC Mayo score and fcal should be prioritized for identifying the IBD population requiring supplementation. Funding Agencies None

Vitamin D deficiency/insufficiency has been primarily associated with skeletal disorders, however, since vitamin D receptors are found on multiple types of cells, there is also a link to increased chronic disease risk and all-cause mortality. The aim of this study was to examine whether deficient/insufficient vitamin D levels are associated with risk factors of chronic diseases and cognitive dysfunction in 50 to 70 year old adults. Participants completed the health status, three-day dietary record and vitamin D food frequency, sun exposure, and international physical activity questionnaires. Cognitive function of the participants was assessed using the Automated Neuropsychological Assessment Metrics while body composition (percent body fat, android/gynoid ratio) was assessed using Dual Energy X-ray Absorptiometry. Applanation tonometry was used to obtain pressure wave forms at the radial artery to examine arterial stiffness and central pressures. A fasting blood draw was taken to measure vitamin D, blood lipid and glucose levels. Fifty percent of the participants (36/72) were vitamin D deficient/insufficient. Individuals in the low physical activity (PA) group had lower serum vitamin D concentration compared to those in the high PA group (p = 0.04). Moreover, serum vitamin D levels were negatively related to risk factors of chronic diseases; blood glucose (r = −0.38; p = 0.01), triglycerides (r = −0.27; p = 0.02), and android/gynoid ratio (r = −0.32; p = 0.01). Deficient/insufficient vitamin D levels are linked to the risk factors of chronic diseases in men and women aged 50 to 70 years.
