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: Vitamin D plays an important role in maintaining calcium and bone metabolism, a risk factor of osteoporosis, fall and fracture in old age. Reduction in D-vitamin levels associated with compensatory increased level of parathyroid hormone causes significant loss of bone matrix, so substitutions of vitamin D and calcium are very important. Many authors publish their recommended doses used for prevention of hip fracture during the last years. Some authors are satisfied only with vitamin D supplementation while others have better experiences with vitamin D and calcium substitution. On the other hand, some metaanalyses give contradictory results and propose further investigations. It is important to consider the patients’ eating habits and lifestyle as well as the risk of cardiovascular and other chronic diseases. Further trials should be done in different age groups in order to examine the effects of different doses of vitamin D without and with calcium to make a final decision.

Lack of adherence with vitamin D supplementation is still a risk factor for rickets. In a randomized cross-over design, infants received 400 IU cholecalciferol by dropper (1 mL syrup) or filmstrip. Infant and parent preference scores and adherence were then compared. Forty-three parents of healthy infants preferred the filmstrip (85.4% of parents; 95% confidence interval of 70.1%–93.9%; p < 0.001), a result that was corroborated by higher infant and parental scores and compliance. Ease of administration of supplements with improved acceptance may improve adherence.

Structured abstractImportanceVitamin D deficiency increases the incidence of respiratory virus infections. More than 1 billion people worldwide are vitamin D deficient. If vitamin D deficiency is associated to incidence or severity of SARS-CoV-2 infection, a global call could be made for vitamin D supplementation to mitigate the pandemic.Objectiveto determine if lower serum 25-hydroxyvitamin D (25(OH)D) levels are correlated to the risk for COVID-19 and its severity as measured by CTDesignsingle-center observational studySettingAZ Delta general hospitalParticipants186 consecutive patients with PCR-confirmed SARS-CoV-2 infection hospitalized for COVID-19 from March 1, 2020 to April 7, 2020Main outcome and measurescomparative analysis of 25(OH)D levels in patients hospitalized for COVID-19 at various radiological stages and a season/age/sex-matched diseased control populationResultswe report on 186 SARS-CoV-2 infected patients requiring hospitalization for severe COVID-19: 109 males (median age 68 years, IQR 53–79 years) and 77 females (median age 71 years, IQR 65–74 years). At admission patients were screened by CT to determine temporal changes of COVID-19 lung disease and classified as stage 1 (ground glass opacities), 2 (crazy paving pattern) and 3 (consolidation). At intake, 25(OH)D levels were measured and compared to a season-matched population of 2717 diseased controls, consisting of 999 males (median age 69 years, IQR 53–81 years) and 1718 females (median age 68 years, IQR 43–83 years). Male and female COVID-19 patients combined showed lower median 25(OH)D than controls (18.6 ng/mL, IQR 12.6–25.3, versus 21.5 ng/mL, IQR 13.9–30.8; P=0.0016) and a higher fraction of vitamin D deficiency (58.6% versus 45.2%, P=0.0005). A strong sexual dimorphism was found: female patients had comparable vitamin D status as control females. Male COVID-19 patients, however, showed markedly higher percentage of vitamin D deficiency than controls (67.0% versus 49.2%, P=0.0006) and this effect was more pronounced with advanced radiological stage ranging from 55.2% in stage 1 to 74% in stage 3.Conclusions and relevancevitamin D deficiency is a possible risk factor for severe SARS-CoV-2 infection in males. Vitamin D supplementation might be an inexpensive, accessible and safe mitigation for the SARS-CoV-2 pandemic.Key pointsQuestion: does vitamin D deficiency predispose to severity of SARS-CoV-2 infection?Findings: in this observational study on 186 consecutive patients hospitalized with PCR-confirmed SARS-CoV-2 infection, we find that patients with severe COVID-19 show lower median serum 25(OH)D and a higher percentage of vitamin D deficiency at intake than a season/age-matched reference population. The correlation between vitamin D deficiency and the need for hospitalization due to COVID-19 was only seen in male patients. In males but not females, the percentage of vitamin D deficient patients also increased with more advanced COVID-19 disease stage as measured by CT.Meaning: our data indicate a strong statistical correlation between the degree of vitamin D deficiency and severity of COVID-19 lung disease. With more than 1 billion people worldwide affected by vitamin D deficiency, vitamin D supplementation might be a lifesaving, inexpensive, accessible and safe component of primary prevention during the SARS-CoV-2 pandemic and beyond

Objective: Observe the clinical characteristics of children with SLE, namely, to observe the symptoms and laboratory examinations, such as blood routine, blood lipid, immunoglobulin, complement, autoantibodies, serum 25 (OH) D and other indicators, and to explore the clinical characteristics, the difference and the significance of vitamin D supplements between male and female SLE patients in children respectively. Methods: We enrolled 64 cases of SLE patients in children who were admitted into the department of pediatrics and rheumatology of the third affiliated hospital of sun yat-sen university in guangzhou from May 1, 2011 to February 1, 2019, They were analyzed retrospectively, adopting ?² test for statistical analysis. Results: 64 cases of SLE in children, which included 10 cases of male and 54 cases of female. Clinical manifestations: facial skin rash in 48 patients (75%), fever in 38 cases (59.4%), arthritis in 28 cases (43.8%), oral ulcer in 18 cases (28.1%), serositis in13 cases (20.3%), and the sun allergy in 9 cases (14.1%), the damage of central nervous system in 7 cases (10.9%) . Laboratory examination: 30 cases of leukopenia (46.9%), anemia in 30 cases (46.9%), thrombocytopenia in 12 cases (18.8%), hematuria in 18 cases (28.1%), proteinuria in 33 cases (51.2%), 6 patients with renal impairment (9.4%), antinuclear antibody positive in 63 cases (98.4%), anti-double-stranded DNA (dsDNA) antibody positive in 48 cases (75%), anti SSA antibody positive in 44 cases (68.7%), SSB antibody positive in 33 cases (51.6%), Sm antibody positive in 40 cases (62.5%), nucleosome antibody positive in 28 cases (43.8%) .Among these children, male SLE patients were higher than female children with SLE in the damage of kidney, Sm antibodies and resisting nucleosome antibody positive rates (?²= 4.451, 8.336, 6.803, P<0.05), the female children with SLE was higher than male SLE Children in the anti-SSB antibody positive rate (?²=4.945, P < 0.05). In 64 cases of SLE children, which included 52 cases were lower than the normal level of serum 25 (OH) D measurements, 12 cases were in the normal lower limit of serum 25 (OH) D measurements, at the same time, the female SLE. Patients was higher than male children with SLE in the reduce rate of serum 25 (OH) D (?²= 8.351, P < 0.05). Conclusion: Male SLE patients which appeared damage of kidney easier than female patients , the proteinuria was the most common in the damage of kidney. Resistance to Sm antibodies which was the risk factor of renal injury with higher incidence in male children with SLE; Anti nucleosome antibody which was the risk factor for the disease activity in male children with SLE were higher than female children with SLE. It was estimated that the risk of Sjogren's syndrome appeared in female with SLE were higher than that in male SLE children. In this retrospective study, the serum 25 (OH) D levels were significantly lower in children with SLE, and vitamin D supplementation was required.

Background: Several risk factors are associated with multiple sclerosis (MS) progression and may be amenable to intervention. Objective: To systematically review the evidence for interventions targeting risk factors for MS progression. Methods: We searched six databases and existing reviews till March 2015 and consulted with experts to identify randomized controlled trials (RCTs) of interventions targeting MS risk factors (PROSPERO 2015:CRD42015016461). Results: In total, 37 RCTs met inclusion criteria. Expanded Disability Status Scale (EDSS) scores after exercise interventions did not differ compared with untreated controls (standardized mean differences (SMDs): 0.02; confidence interval (CI): −0.40, 0.44; I2: 0%; seven RCTs; very low quality of evidence (QoE)). Dietary interventions did not show a statistically significant effect on the relative risk (RR) of progression (RR: 0.86; CI: 0.67, 1.05; I2: 0%; four RCTs; moderate QoE) compared to placebo. EDSS scores after vitamin D supplementation were not significantly different from placebo (SMD: −0.15; CI: −0.33, 0.02; I2: 0%; five RCTs; very low QoE). Conclusion: We did not identify any risk factor interventions with significant effects on MS progression, but the overall QoE was limited. More adequately powered trials are needed on vitamin D supplementation, long-term exercise, and smoking cessation.
