Abstract Background This study aimed to investigate the relationship between maternal serum vitamin D status in the first trimester of pregnancy and maternal as well as neonatal outcomes, considered the prevalence of vitamin D deficiency (serum 25(OH)D < 50 nmol/L) around the world, especially in the pregnant women. Methods From January 2015 to December 2016, in this cross-sectional retrospective study, we enrolled women receiving regular prenatal examinations and giving birth in the International Peace Maternity and Child Health Hospital. Cases confirmed as multiple pregnancy, incomplete medical records, and vitamin D level recorded after 13 weeks of gestation were excluded. A total of 23,394 mother-infant pairs were included ultimately. Obstetric and neonatal information were extracted from the database. Maternal serum vitamin D concentration was measured by chemiluminescence microparticle immunoassay. Logistic regression analysis (unadjusted and adjusted models) was used to analyze the association between vitamin D and maternal and neonatal outcomes. Results The average 25(OH) D concentration was 43.20 ± 0.10 nmol/L; 67.09% of patients were vitamin D deficient(25(OH) D < 50.00 nmol/L), 29.84% were vitamin D insufficient (50 nmol/L ≤ 25(OH)D < 75 nmol/L), 3.07% were sufficient (25(OH)D ≥ 75 nmol/L). The maternal 25(OH)D levels varied with age, pre-pregnancy BMI, season when blood sample was collected, number of previous-pregnancy. Notably, newborns delivered by women with deficient vitamin D status had a higher incidence rate of admission to NICU (Deficiency: 12.20% vs Insufficiency: 10.90% vs Sufficiency: 11.70%, Pbonferroni = .002) and a longer stay (deficiency: 6.2 ± 4.1 days vs insufficiency: 5.9 ± 3.1 days vs sufficiency: 5.1 ± 2.1 days, Pbonferroni = .010). Moreover, maternal vitamin D deficiency was a dependent risk factor for admission to NICU (unadjusted OR = 1.35, 95% CI,1.05–1.74 Pbonferroni = .022; adjusted OR = 1.31, 95% CI,1.010–1.687 Pbonferroni = .042). Conclusions Maternal vitamin D deficiency (25(OH) D < 50 nmol/L) was prevalent in eastern coastal China. The incidence rate of GDM as well as preeclampsia was higher in vitamin D insufficient group while vitamin D deficiency group was liable to intrauterine infection when compared with the other two groups. Most importantly, low vitamin D status in the first trimester of pregnancy was a dependent risk factor for admission to NICU. More well-designed perspective researches are necessary to clarify the role of vitamin D in the early stage of pregnancy.

Abstract Background: This study was thus undertaken to study the estimation of vitamin D levels in pregnant women and their newborns in DRC and to study its association with various neonatal outcomes. Methods: Observational study done on 569 pregnant women and their newborn babies. Sample obtained from maternal serum and cord blood from the placental end during peripartum period. The data was analysed to estimate the prevalence of vitamin D levels in mothers and newborns and to identify association, if any, between maternal vitamin D levels and neonatal outcomes.Results: 464 mothers had sufficient vitamin D (VDS) levels (>30 ng/dL) and 105 had vitamin D deficiency (VDD) with mean maternal serum vitamin D level of 35.63ng/ml (SD 6.18, range 9.2-39.8). All the newborns (n=569) were vitamin D deficient (<30ng/ml). The percentage of LBW babies born to VDD mothers was 18.09%, which was very similar to the percentage of LBW babies born to VDS mothers (18.31%) (p=0.76456749). The incidence of caesarean section was 58.09% in the vitamin D deficient (VDD) group as compared to 19.61% in the sufficient (VDS) group (p<0.0005). The incidence of preterm births was 10.77% in the sufficient group (VDS) as compared to 17.14% in the vitamin D deficient (VDD) group (p=0.038). Conclusion: Our findings will help health professionals, policy makers, and the general public in Africa aware of the high prevalence of vitamin D deficiency and the associated health risks.

Spontaneous Pregnancy

Background: Pregnancy loss in the first trimester is one of the most disappointing matters for a mother. But spontaneous pregnancy loss in the first trimester is the most common negative outcome of pregnancy. It's estimated that about 10% of known pregnancies are lost in the first trimester whereas fewer than 4% of pregnancies miscarry in the second trimester. Aim of current study was to assess the effect of the maternal vitamin D level on the risk of spontaneous pregnancy loss in the first trimester.Methods: It was a case-control study conducted in the department of obstetrics and gynecology, Sir Salimullah medical college Mitford hospital, Dhaka, Bangladesh during the period of September 2018 to August 2019. A total of 100 patients were included in this study. Statistical analyses of the results were obtained by using window-based computer software devised with SPSS version 22.0.Results: In analyzing the association of serum vitamin D status with first-trimester pregnancy state it was observed that more than half (52.0%) patients had severe deficiency (<10 ng/ml) in the case group and 14 (28.0%) patients in the control group. In total 24 (48.0%) patients had deficiency (10-20 ng/ml) in case and 35 (70.0%) in control group. Only 1 (2.0%) patient had insufficiency (21-29 ng/ml) in control group. The difference was statistically significant (p<0.05) between the two groups.Conclusions: Maternal serum vitamin D deficiency was significantly associated with early spontaneous pregnancy loss in the first trimester.

Aim: To determine the relationship between maternal serum 25(OH) D concentrations and development of preeclampsia. Study Design: A cross sectional comparative study. Place and Duration of Study: Department of Obstetrics and Gynaecology, University of Abuja Teaching Hospital, Abuja, between March 2016 and February 2017. Methodology: We included 55 women with preeclampsia and 55 healthy women. Data obtained included sociodemographic characteristics, clothing style and duration of exposure to sun light.  ELISA method was used for evaluation of serum vitamin D levels. Results: The prevalence of VD deficiency in the population was 15%, while 16.8% and 73% of the participants had insufficient and normal levels respectively. The prevalence of VD deficiency in women with preeclampsia was 20.4% while that in healthy pregnant women was 9.4% (P=.19). The mean serum 25-OH-D level of women with pre-eclampsia was significantly lower than that of healthy women (34.5±14.9 vs. 43.5±15.1, P = .003). Preeclamptic women with vitamin D insufficiency delivered at a higher gestational age than those with vitamin D deficiency (37.67(2.77) weeks vs. 33.55(2.38) weeks respectively, P = .007). In the adjusted analysis of cases with vitamin D defficiency, the odds of developing preeclampsia was not statistically significant [odds ratio (OR) = 3.27, CI = 0.99-10.83, P =.05].  However, the odds of developing preeclampsia in women with Vitamin D insufficiency was statistically  significant (OR = 3.20, CI = 1.02–10.06,  = 0.046). Conclusion: In conclusion, an association between vitamin D deficiency and preeclampsia was not demonstrated in this study. The results however suggest that maternal vitamin D insufficiency in late pregnancy is an independent risk factor for preeclampsia.

Objective: Vitamin D deficiency is a major health problem in all age groups. In the present study, we aimed to determine the prevalence of vitamin D deficiency in neonates hospitalized in an intensive care unit (NICU) and its association with clinical neonatal outcomes. Materials and methods: A prospective cross-sectional study was carried out on all neonates hospitalized in the NICU of Children's Medical Center over a period of one year (January–December 2018). Immediately on admission, a serum sample for vitamin D measurement was obtained with another routine blood sampling. Demographic and clinical data including sex, gestational age, the season of birth, serum levels of vitamin D and calcium, the causes of hospitalization, age at admission and neonatal outcomes including length of hospital stay and mortality during hospitalization were assessed. Results: One hundred neonates entered the study. Vitamin D deficiency and insufficiency were present in 95% of neonates. There was a significant association between vitamin D status and birth during winter (p=0.014); hypocalcemia (p=0.025) and older age at NICU admission (p<0.001). The mean value of vitamin D in term neonates was significantly lower than in preterm neonates (p=0.031). There were no correlations between length of hospital stay and neonatal mortality rate with vitamin D status (p=0.876). Conclusion: Vitamin D deficiency and insufficiency were highly prevalent among NICU patients. Maternal vitamin D supplementation during pregnancy may prevent or reduce the risk of low levels of vitamin D in neonates.

AbstractObjectiveTo assess vitamin D status among Cypriot adolescents and investigate potential determinants including BMI and body fat percentage (BF%).DesignParticipants had cross-sectional assessments of serum vitamin D, physical activity, dietary vitamin D intake and sun exposure. Linear and logistic regression models were used to explore the associations of vitamin D with potential predictors.SettingHospitals, Cyprus, November 2007–May 2008.SubjectsAdolescents (n 671) aged 16–18 years.ResultsMean serum vitamin D was 22·90 (sd 6·41) ng/ml. Only one in ten children had sufficient levels of vitamin D (≥30 ng/ml), while the prevalence of vitamin D deficiency (12–20 ng/ml) and severe deficiency (<12 ng/ml) was 31·7 % and 4·0 %, respectively. Lower vitamin D was associated with winter and spring season, female gender, reduced sun exposure in winter and darker skin. Participants with highest BMI and BF% when compared with a middle reference group had increased adjusted odds of vitamin D insufficiency (OR = 3·00; 95 % CI 1·21, 7·45 and OR = 5·02; 95 % CI 1·80, 13·97, respectively). A similar pattern, although not as strong, was shown for vitamin D deficiency with BF% (OR = 1·81; 95 % CI 1·04, 3·16) and BMI (OR = 1·51; 95 % CI 0·85, 2·67). Participants in the lowest BMI and BF% groups also displayed compromised vitamin D status, suggesting a U-shaped association.ConclusionsVitamin D deficiency in adolescence is very prevalent in sunny Cyprus, particularly among females, those with darker skin and those with reduced sun exposure in winter. Furthermore, vitamin D status appears to have a U-shaped association with adiposity measures.

Abstract Background: Neonates could be strongly affected by vitamin D deficiency-related adverse effects. In the present study, we aimed to determine the prevalence of vitamin D deficiency in the neonatal intensive care unit (NICU) hospitalized neonates and its possible relationship with neonatal outcomes. Methods: A prospective cross-sectional study was carried out in the NICU of Children's Medical Center (Tehran-Iran; 2015). The population study was NICU hospitalized neonates. Immediately on admission, serum sample for vitamin D measurement was obtained with routine blood sampling. Demographic and clinical data including serum levels of vitamin D and calcium, the causes of hospitalization, and neonatal outcome were recorded. The prevalence of vitamin D deficiency and its association with neonatal outcome were assessed. Results: One-hundred subjects entered the study. Vitamin D deficiency and insufficiency were present in 95% of neonates. There was a significant association between vitamin D status and season of birth (p=0.014); calcium status (p=0.025) and age at NICU admission (p<0.001). The mean value of vitamin D in term neonates was significantly lower than preterm neonates (p=0.031). There were no correlations between neonatal mortality with vitamin D (p=0.876) status.Conclusion: Vitamin D deficiency/insufficiency was highly prevalent among our NICU hospitalized neonates. There was no association between vitamin D level and neonatal outcomes. Neonates' vitamin D statuses were significantly correlated with the neonate's age at hospital admission, calcium status and season of birth. The measurement of serum vitamin D along with other routine blood tests in neonates who need NICU admission was strongly recommended.

Background: Vitamin D deficiency has been associated with various poor maternal and fetal outcome and is proposed to be important in the pathogenesis of preeclampsia. The aim of the study was to evaluate the serum vitamin-D levels in normal pregnant females and pre-eclampsia or eclampsia individuals in the third trimester admitted for termination or in labour and to assess the neonatal outcome and neonatal serum calcium levels of babies born to mother in both the groups.Methods: This study was a prospective comparative study carried out on the pregnant women in the third trimester admitted for termination or in labour. 100 pregnant females with either pre-eclampsia or eclampsia were compared with equal number of normotensive pregnant females for serum vitamin D. They were followed up until delivery and subsequently neonatal serum calcium level was estimated.Results: Most pregnant females had vitamin D deficiency pointing towards universal prevalence. Only 10% had suboptimal to optimal vitamin D level while 90% had vitamin deficiency. The hypertensive group had lower mean serum vitamin D level (9.06±5.20 ng/ml) as compared to normotensive group (13.67±7.24 ng/ml). Neonatal outcome was poorer in the hypertensive group. Neonates born to hypertensive mothers had lower mean calcium level (8.30±1.46mg/dl) when compared to those born to normotensive mothers (8.82±0.918mg/dl).Conclusion: The study findings revealed that there lies a consistent association of maternal serum vitamin D deficiency with the hypertensive disorders of pregnancy and neonatal morbidity.

Background: Low vitamin D levels are common in patients with foot and ankle disorders. We have previously demonstrated that juveniles diagnosed with osteochondritis dissecans (OCD) have a high prevalence of vitamin D deficiency. Moreover, there is evidence that OCD might be related to vitamin D deficiency in general. However, whether or not hypovitaminosis D is associated with OCD of the talus has yet to be elucidated. Methods: The aim of this study was to determine serum vitamin D levels [25(OH)D] of patients diagnosed with traumatic and idiopathic OCD of the talus. The vitamin D status of patients was measured and correlated to age, sex, season, etiology, laterality, degree of disease, and nicotine abuse. Moreover, parathyroid hormone and serum calcium levels of patients were obtained to assess for severe vitamin D deficiency and secondary hyperparathyroidism. Between January 2015 and December 2017, 65 patients with a mean age of 38.9 years and a total of 68 lesions were identified. Results: In total, 75.4% of patients had low vitamin D levels with a mean overall 25(OH)D level of 24.2 ng/mL. Specifically, 35.4% of patients were vitamin D deficient; another 40% were vitamin D insufficient, and only 24.6% of patients presented with sufficient vitamin D levels. Statistical analysis showed no significant difference comparing vitamin D levels of patients with idiopathic OCD to patients with traumatic OCD. Conclusion: We could not find any significant differences in the vitamin D status of patients with OCD of the talus compared with patients with foot and ankle disorders in general. However, we found that vitamin D deficiency was frequent in patients presenting with traumatic and idiopathic OCD of the talus. We believe it might be beneficial to routinely assess and treat the vitamin D status of patients. Level of Evidence: Level III, retrospective comparative study.

Background: Recently, we see in our clinical practice that many patients who are coming with generalized body aches and pains and diagnosed as fibromyalgia or chronic fatigue, not adequately responding to treatment. When their vitamin D level was done, it was found to be low and correction of their low vitamin D level improved their symptoms dramatically. Despite abundant sunshine in Bangladesh, allowing vitamin D synthesis all the year round, why our people are developing hypovitaminosis D inspired us to do this current study. Our present study is designed to estimate the prevalence of vitamin D deficiency among adult patients presented with aches & pains as well as to study the association of low vitamin D levels with different socio-demographic parameters.Methods: A cross sectional observational study was conducted among 212 adult patients aged 18 years and above presented with generalized body aches and pains, attended both outpatient and inpatient departments of Popular Medical College Hospital during the period of March’16- August’16 ( 6 months). Association between vitamin D status & the individual specific variables was statistically analyzed.Results: The prevalence of vitamin D deficiency among the study population was found to be100% in all age groups. Among 212 study population, 73.6% were female (n=156) & 26.4% were male (n=56). Mean Vitamin D level among male was 14.29 (SD 4.68) & among female was 12.64 (SD 4.74). The factors associated with severely deficient Vitamin D level were female sex, urban population, &obesity. It is alarming that 64.2% of our study population were totally unaware about the importance of sun exposure.Conclusions: Vitamin D status was associated with a number of socio-demographic variables. Knowledge of these variables may improve targeted education and public health initiatives.J MEDICINE Jan 2018; 19 (1) : 22-29

Abstract. Background & Aims: Epilepsy affects nearly 70 million people worldwide. Vitamin D deficiency may influence the balance of certain epilepsies. The purpose of this study was to determine the vitamin D status and anthropometric measurements of people with epilepsy (PWE), according to their pharmacosensitivity. Methods: Forty-six PWE, with or without drug resistance, underwent nutritional assessment after giving consent. Weight, body mass index (BMI), triceps skinfold thickness (TSF), fat mass (FM) and free fat mass (FFM) by bioelectrical impedance analysis were measured. Serum vitamin D was determined without supplementation. Deficiency was defined as a level < 30 ng/mL. Statistical analysis involved Student t test, ANOVA and Chi2. Results: Patients were aged 44.5 ± 14.3 years, with 60.9% of drug-resistance. BMI was 28.7 ± 7.0, 2.2% were malnourished and 30.4% obese according to the BMI. The average vitamin D level was 15.3 ± 9.9 ng/mL, with 87.0% of deficiency, and 40.0% of severe deficiency (<10 ng/mL). The TSF was higher in drug-resistant cases (p = 0.03). There was no link between drug resistance and anthropometric measurements, FM, FFM or vitamin D concentration. Conclusions: Although limited in size, this study showed that PWE are more often obese. Vitamin D deficiency is more common than in the general population, with a much higher prevalence of severe deficiency.
