Abstract Objective: The aim of this study was to determine, retrospectively, the serum 25OHD and calcium concentrations of screened neonates of mothers at high risk of 25OHD deficiency (maternal 25OHD < 25 nmol/L or unknown vitamin D concentrations and risk factors for vitamin D deficiency) and critically analyse whether their measurements contributes to the management of these neonates. Methods: Serum 25OHD and calcium concentrations from 600 samples of umbilical cord blood or venous blood collected from neonates over a 12-month period were analysed. 25OHD concentrations were reported for all while both the corrected calcium concentrations and vitamin D concentrations were available for 569 samples. Results: There was little or no evidence of association between neonatal 25OHD concentrations and gender, gestational age or birth weight. There was a high prevalence of vitamin D insufficiency (27.6%, 30–50 nmol/L) and deficiency (21.3%, < 30 nmol/L) in neonates from high-risk maternal groups. There was a statistically positive but weak correlation (ρ = 0.22, P < 0.0001) between serum calcium and 25OHD concentrations. Only 7 neonates out of 569 (1.2%) had calcium levels in the hypocalcaemic range; however, a significant number (47.6%) were reported to be in the hypercalcaemic range. Nearly all of these were venous samples collected in first 24 hours after birth. We calculated the reference interval for corrected calcium from our data of venous samples in first 24 hours and the upper limit was significantly higher (2.38–3.04 mmol/L) than the standard reference range used. Conclusion: Vitamin D deficiency is prevalent in neonates of high-risk mothers but the risk of hypocalcaemia due to vitamin D deficiency at birth is low. Screening neonates entails blood testing which can cause distress to neonates and their parents, substantial impost on staff and financial burden on the health care system. 25OHD deficiency is corrected relatively easily in neonates with supplementation and vitamin D supplementation of neonates from birth without routine screening appears to offer better value of care. Also, the data from this study suggest that the paediatric reference range for corrected calcium concentrations in neonates is higher and the paediatric reference range should be reconsidered.

AbstractThe incidence of vitamin D deficiency is high globally, and vitamin D supplementation draws particular attention. The objective of this study was to investigate the effects of stratified vitamin D supplementation in middle-aged and elderly individuals with vitamin D insufficiency in Beijing. A total of 448 subjects aged over 40 years old were selected from a community in Beijing. Among them, 100 middle-aged and elderly people with vitamin D insufficiency were randomly selected on a voluntary basis. They were further divided into control group and intervention group. The control group received health education and lifestyle guidance, and the intervention group received lifestyle guidance and vitamin D supplementation for nine months. The doses were stratified as follows: for vitamin D insufficiency, oral vitamin D3 supplement was given at 5000 IU/w; for mild vitamin D deficiency, oral vitamin D3 supplement was given at 10 000 IU/w; for severe vitamin D deficiency, oral vitamin D3 supplement was given at 15 000 IU/w. Safety evaluation was conducted after three-month treatment. The intervention group consisted of 8%, 62%, and 30% of cases who had vitamin D insufficiency, mild vitamin D deficiency, and severe vitamin D deficiency, respectively, which were similar with the control group. It showed that the blood 25(OH)D level increased significantly in the intervention group, from 14.30±4.30 ng/ml to 33.62±6.99 ng/ml (p<0.001), in contrast to insignificant change in the control group. Stratified vitamin D supplementation effectively increased the blood 25(OH)D level, as well as the number of cases with corrected vitamin D insufficiency or deficiency.

AimsTo audit the investigation, identification and treatment of Vitamin D deficiency within Men's Secure Services.BackgroundVitamin D and/or vitamin D deficiency has been suggested to play a role in the pathogenesis of mental illness. There is evidence that Vitamin D inadequacy is pandemic among rehabilitation patients in inpatient settings. Patients within secure hospitals are similarly considered to be at high risk, due to their limited solar exposure during often lengthy admissions. It has been suggested that these patients should be considered an ‘at-risk’ cohort, for whom Vitamin D supplementation should be routine. Men's secure services in Birmingham comprise of two medium secure units and a low secure rehabilitation unit. Here we present an audit of Vitamin D monitoring and treatment completed in 2019.MethodA three year retrospective review of electronic patient records, for all inpatients admitted within men's secure services as of 1 September 2019 (n = 188). Standards were based on the Trust accepted guidelines for management of Vitamin D deficiency.ResultKey findings included:- The majority of inpatients were Caucasian (43%) and African-Caribbean (24%). Ages ranged from 18 to 70, with a mean age of 39.Approximately two-thirds (65%) had been in hospital for over a year, of which 44% had been admitted for more than 3 years. The average length of admission was 885 days.Only 47% of patients had their Vitamin D level checked within the study period.Of those checked, 24% were tested within 1 month of admission. The mean duration between admission and Vitamin D testing was 464 days.Results ranged from 10.3 to 118.5nmol/L. A high rate of Vitamin D deficiency was identified (54%), whilst a further 16% had ‘inadequate’ levels.23% of those identified as requiring treatment did not receive any supplementation, whilst 59% of those with sufficient Vitamin D were prescribed treatment.Only 48% had their levels rechecked following treatment; of these, only 59% now had an adequate Vitamin D status.ConclusionThis audit demonstrates limited Vitamin D monitoring within male forensic inpatients. There was a high prevalence of Vitamin D insufficiency in this population, yet a substantial proportion of patients with identified deficiency were not prescribed any treatment. Ongoing monitoring and review of treatment effectiveness was poor. We argue that more consideration should be given to this population, with robust guidelines introduced for the treatment of this specific ‘at-risk group’.

Abstract Background Vitamin D deficiency represents a global health problem, affecting children and adolescents worldwide. Objects To confirm that vitamin D deficiency can present as a spectrum of clinical pictures. Methods We diagnosed nutritional rickets in a 10-month-old infant of Senegal origin with several risk factors for vitamin D deficiency. As many of these factors affected also his cohabitant relatives, we evaluate infant’s family members (mother and 4 brothers) looking for other vitamin D deficiency-related comorbidities. Results 3 brothers had asymptomatic vitamin D deficiency and 2 of them (9.8 and 13.4 years-old) showed secondary hyperparathyroidism. The fourth brother (11.3 years-old) had nutritional rickets. Their mother was affected by osteomalacia. None of them received vitamin D supplementation. Conclusion Vitamin D deficiency may present as a spectrum of clinical pictures, representing a continuum ranging from asymptomatic/subtle conditions to overt rickets/osteomalacia. Immigrant families are at high risk for vitamin D deficiency at every age. If a case of symptomatic vitamin D deficiency is recognized, then the evaluation of the all family members is recommended, as they can have the same and/or other risk factors for vitamin D deficiency.

Background: Preeclampsia (PE) is a disease specific to pregnancy affecting many bodily systems. This is characterized by high blood pressure and proteinuria after the 20th week of pregnancy. The objective of this study was to evaluate of association of vitamin D insufficiency with gestational hypertension in pregnant women.Methods: This was a cross-sectional study. A total of 104 pregnant women were included in the study. The diagnosis of gestational hypertension was confirmed using the “Report of the American College of Obstetricians and Gynaecologists’ Task Force on Hypertension in Pregnancy” criteria. Based on these criteria, patients with systolic blood pressure ≥140 mmHg and/or diastolic blood pressure ≥90 mmHg (measured after a period of rest of four hours, twice daily) and proteinuria (≥300 mg protein/24 h) were diagnosed as gestational hypertension.Results: Vitamin D deficiency was found among 78.9% (90/114) women. There was no significant (p >0.05) difference in age of women between vitamin D deficient and sufficient. Vitamin D level was significantly (p = 0.0001) lower among the women between Vitamin D deficient (15.93±4.66) and sufficient (35.70±3.25). There was no significant (p >0.05) association of Vitamin D level with parity, family history of hypertension, blood pressure, gestational age and fasting blood glucose. There was significant (p = 0.0001) difference in BMI between Vitamin D deficient (30.10±4.95) and sufficient (24.04±2.75). Tobacco consumption was also associated with the level of Vitamin D. There was significant negative correlation between BMI and Vitamin D level (r = -0.56, p = 0.00011).Conclusions: The present study demonstrates that vitamin D plays a role in the ethology and pathophysiology of gestational hypertension. Among the population having the risk of vitamin D deficiency, the risk of pregnancy induced hypertension may be decreased through vitamin D supplementation.

Abstract Background : Vitamin D insufficiency and deficiency in childhood are common. However, the status and influential factors of vitamin D during different ages are not clear. This study aimed to survey vitamin D concentrations in children aged 0 to 6 years and explore its influential factors. Methods: A total of 6953 children were recruited in Wuxi City of East China from January to December in 2016. Enzyme-linked immunosorbent assay was used to determine the serum concentrations of 25-hydroxyvitamin D [25(OH)D]. Results: The median vitamin D concentrations in the infant group (0-1 years of age) was 69.40 nmol/L, which were higher than that in both the toddlerhood group (1-3 years of age; 62.30 nmol/L) and the preschool group (3-6 years of age; 50.85 nmol/L). In addition, the median vitamin D concentrations were 71.70 nmol/L in summer, which was higher than that in spring (64.25 nmol/L), autumn (62.95 nmol/L) and winter (64.10 nmol/L). However, no difference was observed between genders ( P = 0.974). Furthermore, the prevalence of vitamin D deficiency (<50 nmol/L) was 48.1% in the preschool group (3-6 years of age), which was higher than the 21.2% vitamin D deficiency in the toddlerhood group (1-3 years of age) and the 17.9% vitamin D deficiency in the infant group (0-1 years of age). Interestingly, a nonlinear association between 25(OH)D and air temperature was observed. Conclusions: A high prevalence of vitamin D deficiency was common in a Chinese population of children 0-6 years old, especially in the preschool-aged children. Therefore, we suggested that we should pay more attention to vitamin D supplementation in Chinese young children.

BackgroundIn response to a resurgence of symptomatic cases of vitamin D deficiency in a high-risk predominantly ethnic minority population, a programme of universal rather than targeted vitamin D supplementation was begun with a public awareness campaign about the importance of vitamin D.ObjectiveTo evaluate the effectiveness of this programme in reducing case numbers.MethodsCases of symptomatic vitamin D deficiency in children under 5 years resident in a primary care trust catchment area presenting at local hospitals were identified through laboratory records of low vitamin D levels which were cross-checked against medical records to confirm the diagnosis. Comparisons were made of the case incidence rate, level of public knowledge and vitamin supplement uptake rate at the onset of the programme in 2005 and 4 years later.ResultsThe number of cases of symptomatic vitamin D deficiency in those under 5 years fell by 59% (case incidence rate falling from 120/100 000 to 49/100 000) despite the supplement uptake rate rising only to 17%. Public awareness of vitamin D deficiency rose to near universal levels.ConclusionsA programme of universal rather than targeted Healthy Start vitamin D supplementation for pregnant and lactating women and young children has led to a substantial decrease in cases of symptomatic vitamin D deficiency in a high-risk population. Supplementation was also started at a younger age than in the national programme. This approach has implications for the delivery of vitamin D supplementation programmes in similar populations.

Aims. Kidney disease was found to be a major risk factor for vitamin D deficiency in a population study of patients hospitalized. The aims of the study were to describe the prevalence of vitamin D deficiency inpatients and outpatients in a nephrology department during fall and to evaluate effect of assessing serum 25-hydroxyvitamin D (25(OH)D) levels and previous supplementation of cholecalciferol on vitamin D status.Methods. We studied 280 subjects in total, between October and January. The subjects were recruited from the following two groups: (a) inpatients and (b) outpatients in nephrology unit. We examined previous documentary evidence of vitamin D supplementation of the patients.Results. The prevalence of vitamin D deficiency among these 280 patients was 62,1% (174 patients). Fifty-three patients (18.9%) had severe vitamin D deficiency, 121 patients (43.2%) moderate vitamin D deficiency, and 66 patients (23.6%) vitamin D insufficiency. In logistic regression analysis female gender, not having vitamin D supplementation history, low serum albumin, and low blood urea nitrogen levels were significant independent predictors of vitamin D deficiency while no association of vitamin D deficiency with diabetes mellitus, serum creatinine, eGFR, and being hospitalized was found.Conclusion. Vitamin D deficiency, seems to be an important problem in both inpatients and outpatients of nephrology. Monitoring serum 25(OH)D concentrations regularly and replacement of vitamin D are important. Women in Turkey are at more risk of deficiency and may therefore need to consume higher doses of vitamin D.

Objective: Uterine myoma is the most common benign tumor however with significant distress and reduced quality of life in affected women. Besides, vitamin D deficiency may be a risk factor for uterine myoma. This study aimed to evaluate the effect of vitamin D supplements on the size of myoma in women with vitamin D insufficiency or deficiency. Materials and methods: This clinical trial was conducted in a teaching hospital from 2019 to 2020. According to baseline vitamin D level, participants were assigned into two interventional equal groups (vitamin D deficiency or insufficiency) to receive either 1000 IU daily or 50000 IU weekly vitamin D for 12 weeks. The size and location of the uterine myoma were compared before and after the intervention. Results: Totally, 137 women with uterine myoma were enrolled. Based on baseline vitamin D level, 52 cases had vitamin D insufficiency and 85 cases had vitamin D deficiency. No significant difference was observed in age and BMI in both groups. The location of the subserosal and intramural myoma did not differ, otherwise, the percent of the submucosal myomas were increased significantly (p=0.020) after the intervention. In both groups decreased myoma size otherwise not significant was seen after the intervention (p=0.148 and p=0.664 respectively). Conclusion: Vitamin D supplementation may not be effective in women with vitamin D insufficiency or deficiency in the short term to reduce myoma size.

Introduction: Vitamin D deficiency is very prevalent in world population and growing evidence shows that also athletes are affected. Vitamin D deficiency causes beside bone disorders, musculoskeletal pain, muscle weakness and is associated with many other health disorders. For athletes in particular it may impair training and performance, prolong recovery and increase risk of injury. We therefore analyzed vitamin D levels in Swiss athletes focusing on prevalence according to age, gender, seasonal variations, indoor or outdoor sports, sunscreen use and vitamin D supplementation. Methods: This study was performed in a convenient sample of 655 Swiss Olympic athletes over one year. Blood samples were obtained and a questionnaire was filled in at Swiss Olympic Medical Centers or Bases during an annual routine exam. Data were then sent to the central laboratory of the Aarau hospital where they were processed and sent to us in an anonymized version. Vitamin D levels were categorized into deficiency (≤ 50 nmol/l), insufficiency (between 50 and 75 nmol/l) and adequate levels (> 75 nmol/l) of 25-hydroxyvitamin D. By means of the questionnaire, we assessed age, gender, type of sport, symptoms possibly related to vitamin D deficiency during the last year, frequency of sunscreen use and vitamin D-containing medications of the athletes. Results: 13.5% of the participants (total number = 651) presented a vitamin D deficiency, 37.8% a vitamin D insufficiency so that more than half of the athletes (51.2%) had inadequate vitamin D levels. Inadequate vitamin D levels were more prevalent in younger athletes, during seasons with lower sun exposure, in indoor sports during the sun deprived seasons, in athletes without vitamines supplementation and in athletes of lower Swiss Olympic classes compared to their counterparts. Conclusions: The results of the study show that the prevalence of inadequate vitamin D levels in Swiss athletes is substantial for younger athletes (< 18 years of age) and for indoor athletes during sun deprived periods of the year. However, a general vitamin supplementation containing vitamin D reduced the prevalence of vitamin D inadequacy which is especially relevant during sun deprived seasons.
