Maternal Iron and Vitamin D Status during the Second Trimester Is Associated with Third Trimester Depression Symptoms among Pregnant Participants in the APrON Cohort. J Nutr 2024; 154:174-184. [PMID: 37984742 DOI: 10.1016/j.tjnut.2023.10.029] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2023] [Revised: 09/21/2023] [Accepted: 10/16/2023] [Indexed: 11/22/2023] Open
Abstract
BACKGROUND The maternal status of multiple micronutrients during pregnancy and postpartum and their potential associations with maternal health outcomes are largely undescribed. OBJECTIVES This study aimed to examine associations between maternal iron and vitamin D status, individually and in combination, on depression symptoms in pregnant individuals. METHODS The Alberta Pregnancy Outcomes and Nutrition cohort study included pregnant participants and their children from Calgary and Edmonton, Canada. Iron biomarkers (serum ferritin [SF], soluble transferrin receptor, and hepcidin) were measured via immunoassays and vitamin D [25-hydroxyvitamin D3 (25(OH)D3) and 3-epi-25-hydoxyvitamin D3 (3-epi-25(OH)D3)] metabolites were quantifed using liquid chromatography with tandem mass spectroscopy. Four categories of maternal iron and vitamin D status during the second trimester were conceptualized using concentrations of SF and total 25-hydoxyvitamin D [25(OH)D], respectively. Maternal Edinburgh Postnatal Depression Scale (EPDS) scores during the third trimester (n = 1920) and 3 mo postpartum (n = 1822) were obtained. RESULTS Concentrations of maternal 25(OH)D3, 3-epi-25(OH)D3, and the ratio of both metabolites were significantly higher during the second trimester compared with their status at 3 mo postpartum. Higher second trimester maternal concentrations of SF (β: -0.8; 95% confidence interval [CI]: -1.5, -0.01), hepcidin (β: -0.5; 95% CI: -0.9, -0.2), and 25(OH)D3 (β: -0.01; 95% CI: -0.02, -0.004) predicted lower maternal EPDS scores during the third trimester. Pregnant individuals with a low iron (SF <15 μg/L) and replete vitamin D (25(OH)D ≥75 nmol/L) (β: 1.1; 95% CI: 0.03, 2.1) or low iron (SF <15 μg/L) and vitamin D (25(OH)D <75 nmol/L) (β: 2.2; 95% CI: 0.3, 4.2) status during midpregnancy had higher third trimester EPDS scores compared with those that were replete in both micronutrients. CONCLUSIONS A higher midpregnancy maternal iron and vitamin D status, independently or in combination, predicted fewer maternal depression symptoms in the third trimester. Concentrations of maternal 25(OH)D3 and 3-epi-25(OH)D3 may be lower in the postpartum period compared with midpregnancy.

Exploring the Role of Mediterranean and Westernized Diets and Their Main Nutrients in the Modulation of Oxidative Stress in the Placenta: A Narrative Review. Antioxidants (Basel) 2023; 12:1918. [PMID: 38001771 PMCID: PMC10669105 DOI: 10.3390/antiox12111918] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2023] [Revised: 10/22/2023] [Accepted: 10/25/2023] [Indexed: 11/26/2023] Open
Abstract
Oxidative stress is a major cellular event that occurs in the placenta, fulfilling critical physiological roles in non-pathological pregnancies. However, exacerbated oxidative stress is a pivotal feature of different obstetric complications, like pre-eclampsia, fetal growth restriction, and other diseases. Compelling evidence supports the relevant role of diet during pregnancy, with pleiotropic consequences for maternal well-being. The present review aims to examine the complex background between oxidative stress and placental development and function in physiological conditions, also intending to understand the relationship between different dietary patterns and the human placenta, particularly how this could influence oxidative stress processes. The effects of Westernized diets (WDs) and high-fat diets (HFDs) rich in ultra-processed foods and different additives are compared with healthy patterns such as a Mediterranean diet (MedDiet) abundant in omega 3 polyunsaturated fatty acids, monounsaturated fatty acids, polyphenols, dietary fiber, and vitamins. Although multiple studies have focused on the role of specific nutrients, mostly in animal models and in vitro, further observational and intervention studies focusing on the placental structure and function in women with different dietary patterns should be conducted to understand the precise influence of diet on this organ.

Relevance of Serum Levels and Functional Genetic Variants in Vitamin D Receptor Gene among Saudi Women with Gestational Diabetes Mellitus. Nutrients 2023; 15:4288. [PMID: 37836571 PMCID: PMC10574375 DOI: 10.3390/nu15194288] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2023] [Revised: 10/04/2023] [Accepted: 10/06/2023] [Indexed: 10/15/2023] Open
Abstract
Background: This study explored the association between ApaI-TaqI Single Nucleotide Polymorphisms (SNPs) in a Vitamin D receptor (VDR) and the risk of Gestational Diabetes Mellitus (GDM) in Saudi women, along with the serum levels of vitamin D. Methods: Ninety women with GDM and 90 non-GDM women were enrolled, based on the inclusion and exclusion criteria for pregnant women enrolled in a single-center study. Blood samples were retrieved from 180 pregnant women using ethylenediaminetetraacetic acid (EDTA) tubes. Serum samples were used to measure the vitamin D, 25-hydroxyvitamin D (25(OH)D or calcidiol), and lipid profiles. Blood was used to measure the hemoglobin A1c levels and to isolate the DNA. The polymerase chain reaction (PCR) was performed for the ApaI (rs79785232), BsmI (rs1544410), FokI (rs2228570), and TaqI (rs731236) SNPs in the VDR gene using restriction fragment length polymorphism analysis. Validation was performed using Sanger sequencing. Statistical analyses were performed between the patients with and without GDM using various statistical software packages. Results: The Hardy-Weinberg equilibrium analysis was statistically significant (p > 0.05). The ApaI, BsmI, and TaqI SNPs were associated with alleles, genotypes, and different genetic models (p < 0.05). Vitamin D levels were associated with deficient levels (p = 0.0002), as well as with a normal and overweight body mass index (p = 0.0004). When vitamin D levels were measured with GDM covariates, the fasting plasma glucose (FPG) (p = 0.0001), postprandial blood glucose (PPBG) (p < 0.0001), oral glucose tolerance test (OGTT)-1 h (p = 0.005), high-density lipoprotein (p = 0.022), and low-density lipoprotein cholesterol (LDLc) (p = 0.001) levels were significantly different. When similar vitamin D levels were measured for each genotype, we confirmed that the ApaI SNP was associated with sufficient levels (p < 0.0001), whereas the BsmI, FokI, and TaqI (p < 0.05) were associated with insufficient levels. The logistic regression model confirmed that the first hour of the OGTT (p = 0.005) was strongly associated with GDM, whereas the analysis of variance confirmed that FPG and PPBG (p < 0.05) were strongly associated with all the SNPs evaluated in the VDR gene. Additionally, the second hour of the OGTT (p = 0.048) and LDLc (p = 0.049) were associated with the ApaI and FokI SNP. Moreover, the first hour OGTT (p = 0.045) and lipid profile parameters (p < 0.05) were associated. Haplotype analysis revealed positive associations among the examined SNPs, which seemed compatible with the hypothesis that variants and combinations of multiple SNP genotypes enhance the risk of GDM in women. Haplotype analysis revealed that different combinations of alleles, such as AGCC, CATT, CGTC, AGTC, and CATT (p < 0.05), were strongly associated. The linkage disequilibrium (LD) analysis showed a strong association with all combinations (p < 0.05). Among the gene-gene interactions, all possible combinations showed a positive association (p < 0.05). Conclusions: Low vitamin D levels were observed in women with GDM. The ApaI, BsmI, and TaqI SNPs were associated with genotype and allele frequencies (p < 0.05). Vitamin D and the SNPs in the VDR gene were associated, according to the ANOVA, logistic regression, haplotype analysis, LD analysis, and the generalized multifactor dimensionality reduction model (p < 0.05).

Abstract
Vitamin D has been found to be involved in glucose metabolism in recent years. Its deficiency is very common, especially in children. Whether vitamin D deficiency in early life affects adult diabetes risk is unknown. In this study, a rat model of early life vitamin D deficiency (F1 Early-VDD) was established by depriving it of vitamin D from the 0 to the 8th week. Further, some rats were switched to normal feeding conditions and sacrificed at the 18th week. Other rats were mated randomly to generate offspring rats (F2 Early-VDD), and F2 rats were fed under normal conditions and sacrificed at the 8th week. Serum 25(OH)D3 level decreased in F1 Early-VDD at the 8th week and returned to normal at the 18th week. Serum 25(OH)D3 level in F2 Early-VDD at the 8th week was also lower than that in control rats. Impaired glucose tolerance was observed in F1 Early-VDD at the 8th week and 18th week and also in F2 Early-VDD at the 8th week. The gut microbiota composition in F1 Early-VDD at the 8th week significantly changed. Among the top ten genera with a rich difference, Desulfovibrio, Roseburia, Ruminiclostridium, Lachnoclostridium, A2, GCA-900066575, Peptococcus, Lachnospiraceae_FCS020_ group, and Bilophila increased owing to vitamin D deficiency, whereas Blautia decreased. There were 108 significantly changed metabolites in F1 Early-VDD at the 8th week, of which 63 were enriched in known metabolic pathways. Correlations between gut microbiota and metabolites were analyzed. Blautia was positively related to 2-picolinic acid, whereas Bilophila was negatively related to indoleacetic acid. Moreover, some of the changes in microbiota, metabolites, and enriched metabolic pathways still existed in F1 Early-VDD rats at the 18th week and F2 Early-VDD rats at the 8th week. In conclusion, vitamin D deficiency in early life leads to impaired glucose tolerance in adult and offspring rats. This effect may be partly achieved by regulating gut microbiota and their co-metabolites.

Abstract
Background: We aimed to investigate the short-term effects of adrenocorticotropic hormone (ACTH) treatment on the adrenal pathway and bone metabolism in patients with epileptic encephalopathy.
Methods: Two groups with 16 patients and 16 controls were formed. Before the treatment, all patients and controls were tested for bone and adrenal metabolism. Twenty doses of ACTH therapy were given to the patient group over 3 months. The tests on the patient group were repeated 1 month after the end of the treatment.
Results: In the patient group, serum calcium, phosphorus and parathyroid hormone levels increased significantly after treatment compared with before treatment. Comparing the bone metabolism of the patient and control groups, urinary calcium/creatinine ratio was higher before treatment; serum phosphorus level, bone-specific alkaline phosphatase level and the urinary calcium/creatinine ratio were higher after treatment in the patient group. In the evaluation of the adrenal pathway, no significant differences were found between fasting serum glucose, sodium, potassium, cortisol and ACTH levels before and after treatment and in the comparison of the patient and control groups.
Conclusion: Our study investigated the short-term effect of ACTH on the adrenal pathway and bone metabolism. The results show that ACTH treatment did not have a negative effect on the adrenal pathway in the early period but, its effects on bone metabolism have not been adequately clarified.

Abstract
Purpose: Vitamin D deficiency is a health problem in developing countries. This study aims to investigate the characteristics of children with vitamin D deficiency in early infancy.
Materials and Methods: Hundred and forty infants with vitamin D deficiency (mean age:3.5 ± 1.7 [0-6] months) and a control group of 200 healthy infants (mean age: 3.4 ± 1.7 [0-6] months) were included in the study. Serum calcium, phosphorus, alkaline phosphatase, parathyroid hormone (PTH), and 25-hydroxyvitamin D (25(OH)D) levels were measured in the patient, control groups, and the mothers of the patients. In 38 patients, radiological findings were evaluated with knee and wrist radiographs. Thacher Rickets Severity Scoring (RSS) system was used for radiological evaluation of rickets severity.
Results: The most common (42%) complaints were respiratory symptoms, including cough, respiratory distress, and wheezing. The most common finding of physical examination was the rachitic rosary. Serum calcium (Ca++), alkaline phosphatase (ALP), 25(OH) vitamin D, and parathormone (PTH) levels were significantly different in the patient and the control groups. The mean Thacher radiological score of 38 patients was 3.1 ± 2.1 (0-8) points. The mother's dressing style of covering up the whole body, i.e., veiling, increased the infant's risk of vitamin D deficiency by 17.5 times.
Conclusion: Subtle clinical, laboratory, and radiological findings of vitamin D deficiency are detected in early infancy. Vitamin D deficiency should be considered primarily in infants with hypocalcemia whose mothers are less frequently exposed to sunlight due to geographical conditions and their preferred or imposed lifestyle.

Abstract
Epigenetics is a series of alterations regulating gene expression without disrupting the DNA sequence of bases. These regulatory mechanisms can result in embryogenesis, cellular differentiation, X-chromosome inactivation, and DNA-protein interactions. The main epigenetic mechanisms considered to play a major role in both health and disease are DNA methylation, histone modifications, and profiling of non-coding RNA. When the fragile balance between these simultaneously occurring phenomena is disrupted, the risk of pathology increases. Thus, the factors that determine proper epigenetic modeling are defined and those with disruptive influence are sought. Several such factors with proven negative effects have already been described. Diet and nutritional substances have recently been one of the most interesting targets of exploration for epigenetic modeling in disease states, including autoimmunity. The preventive role of proper nutrition and maintaining sufficient vitamin D concentration in maternal blood during pregnancy, as well as in the early years of life, is emphasized. Opportunities are also being investigated for affecting the course of the disease by exploring nutriepigenetics. The authors aim to review the literature presenting vitamin D as one of the important nutrients potentially modeling the course of disease in selected autoimmune disorders.

Abstract
Vitamin D has well-defined classical functions related to metabolism and bone health but also has non-classical effects that may influence pregnancy. Maternal morbidity remains a significant health care concern worldwide, despite efforts to improve maternal health. Nutritional deficiencies of vitamin D during pregnancy are related to adverse pregnancy outcomes, but the evidence base is difficult to navigate. The primary purpose of this review is to map the evidence on the effects of deficiencies of vitamin D on pregnancy outcome and the dosage used in such studies. A systematic search was performed for studies on vitamin D status during pregnancy and maternal outcomes. A total of 50 studies came from PubMed, 15 studies came from Cochrane, and 150 studies came from Embase, for a total of 215 articles. After screening, 34 were identified as candidate studies for inclusion. Finally, 28 articles met the inclusion criteria, which originated from 15 countries. The studies included 14 original research studies and 13 review studies conducted between 2012 and 2021. This review was finally limited to the 14 original studies. This systematic review was conducted according to the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines, and the quality and strength of the evidence was evaluated using the Navigation Guide Systematic Review Methodology (SING). We found evidence that supports the idea that supplementary vitamin D for pregnant women is important for reducing the risk of gestational diabetes, hypertension, preeclampsia, early labor, and other complications. The data retrieved from this review are consistent with the hypothesis that adequate vitamin D levels might contribute to a healthy pregnancy.

Abstract
OBJECTIVE Vitamin D deficiency in pregnant women is of special concern as mother is the only source of vitamin D for the developing fetus, and maternal hypovitaminosis D has been implicated in a number of maternal and neonatal adverse outcomes. The objective of this study was to assess the association of maternal circulating 25-hydroxy vitamin D3 [25(OH)D] concentration with cord blood 25(OH)D and adverse birth and neonatal outcomes. METHODS This prospective cohort study was conducted in Mahatma Gandhi Medical College and Research Institute (MGMCRI) from January 2020 to December 2020. 121 babies born to mothers with singleton pregnancy tested for serum 25(OH)D level on admission for safe confinement were included in the study and cord blood of the babies were sampled for 25(OH)D. Based on the maternal 25(OH)D level, babies were categorized as those born to mothers with sufficient vitamin D level and those born to mothers with hypovitaminosis D (deficient/insufficient) and primary and secondary outcome was compared between two groups. RESULTS Maternal and cord blood hypovitaminosis D was observed in 65% of mothers and 68.6% of babies, respectively. Maternal vitamin D level was the single most significant predictor of cord blood vitamin D level with five-fold increased risk of cord blood hypovitaminosis D in babies born to mothers with hypovitaminosis D. Birthweight (t = -2.219, p = .028) and preterm birth (aOR = 4.417, 95% CI: 1.03-18.9) was significantly associated with maternal hypovitaminosis D and a trend toward increased risk of LBW (aOR - 2.1, 95%CI: 0.6-7.3), SGA babies (aOR - 1.5, 95% CI: 0.5-4.7), perinatal depression (aOR - 1.5, 95% CI: 0.4-5.8) and neonatal hyperbilirubinemia (aOR = 2.68, 95%CI: 0.942-7.6) was observed. CONCLUSIONS Hypovitaminosis D in pregnant women is a significant health issue affecting both the mother and her baby. Safest dose for supplementation during pregnancy to prevent adverse perinatal outcome needs to be evaluated.

Abstract
Background: Abortion is pregnancy termination or loss before 20 weeks gestation or with a fetus delivered weighing <500 grams. One of the pathogenic mechanisms associated with abortion was immunological factors. The human fetus represents a semi-allograft, which cannot survive without maternal immune tolerance. Vitamin D may be implicated in the risk of miscarriage due to its function as an immune modulator and its potential importance for the maternal-fetal immunologic response
Objective: This study aimed to compare the level of serum vitamin D in abortion patients and normal pregnant women.
Methods: This is a cross-sectional study using primary data from a private maternity clinic in October 2020-February 2021. The subjects recruited in this study were 98 women at first-trimester pregnancy with either viable gestation (46 subjects) or abortion (52 subjects). Demographic data (maternal age, gestational age, BMI, parity level, history of miscarriage, and occupation) and their association to abortion were determined. The serum 25(OH)D level was measured and then compared using statistical analysis.
Results: Mean age of the subjects was 30.45 ± 4.56 years and the mean gestational age of the recruitment was 58.31 ± 17.89 days. Abortion group has lower serum 25(OH)D level (16.95 ± 5,51 mg/L) than normal pregnant group (17.89 ± 4,74 mg/L), although it was not statistically significant (P = 0.527). The results also showed there was no statistically significant association between the classification of vitamin D deficiency, BMI, parity level, history of miscarriage, occupation, and abortion (P > 0.05).
Conclusion: In our study, we found that abortion patients had lower vitamin D levels than normal pregnant women, but it was not statistically significant. Abortion also was not associated with BMI, parity level, history of miscarriage, and occupation

Abstract
Background Adherence to standard guidelines is imperative when question comes to disease management. The present study aimed to evaluate the administration of adjunctive vitamin D therapy in various diseases, its adherence to standard guideline and the effect of socioeconomic status on the consumption of vitamin D in children. Methods Cross sectional observational study was conducted among 400 ambulatory pediatric patients at Children’s Hospital, Pakistan Institute of Medical Sciences Islamabad, from November 2017 to June 2018. Data were collected by a self-designed structured questionnaire from the patient’s medical chart. Adjunctive vitamin D therapy adherence was evaluated by the U. S endocrinology clinical practice guideline of vitamin D deficiency. The association between socioeconomic status and consumption of vitamin D was examined by chi-square. Alpha value (p ≤ 0.005) was considered statistically significant. Statistical analysis was done by SPSS version 25. Results In 400 patients, 9 diseases and 21 comorbid conditions were identified, in which adjunctive vitamin D therapy was prescribed. Adherence to vitamin D testing in high-risk vitamin D deficiency diseases as; seizures (3.8%), bone deformities (13.3%), steroid-resistant nephrotic syndrome (0.0%), cerebral palsy (5.9%) and meningitis (14.3%). Adherence to prescribed vitamin D dose was in (41.3%) patients in various diseases. Significant association (p < 0.05) was found between socioeconomic status and consumption of vitamin D in children and mothers. Conclusions It was found that adjunctive vitamin D was being prescribed in various diseases and comorbidities. Overall poor adherence to the standard guideline was observed in disease management in children. Low socioeconomic status affects vitamin D supplementation consumption in children.

Abstract
OBJECTIVES To determine vitamin D supplementation frequency among children aged 1-24 months, factors that influence adherence, and reasons for discontinuation of initiated vitamin D. METHODS This cross-sectional study was conducted using a questionnaire administered to the mothers via face-to-face interview of 560 children aged from 1 to 24 months admitted to outpatient clinics from June to December 2017. RESULTS A total of 351 children were administered vitamin D, and the rate of supplementation in the first year of life was 83%, while it was only 28% between 13 and 24 months. The rate of vitamin D supplementation was higher among exclusively formula-fed children (p < .05). When the data were analyzed using logistic regression analysis, only visit family physicians were statistically significant independent variable in increasing supplementation (p < .05). Compared with family refusal, the rate of discontinuation of vitamin D by the healthcare providers was higher after the first year of life (p < .05). The rate of vitamin D discontinuation by healthcare providers, especially by nurses who considered the duration of supplementation adequate, was statistically significantly higher when compared with the fontanel closure and other independent variables (p < .05). CONCLUSION The rate of vitamin D supplementation was higher among families who visited family physicians, which suggests the importance of well-baby visits. Since vitamin D supplementation was less common among exclusively breastfed children, mothers should be educated. Healthcare professionals need further education about the importance of vitamin D supplementation and indications for discontinuation.

Abstract
Vitamin D, a fat-soluble vitamin, plays a critical role in calcium homeostasis, the immune system, and normal development. Many epidemiological cohort studies globally have found high prevalence rates of vitamin D deficiency and insufficiency, recognized as an important health issue that needs to be solved. In particular, reproductive age and pregnant women low in vitamin D status may confer risks of diseases like obesity on their offspring. While observational studies have suggested associations between prenatal vitamin D deficiency and metabolic phenotypes in offspring, not yet determined is whether prenatal vitamin D deficiency permanently alters the development of the liver, a major metabolic organ. We tested the histopathology and the transcriptomic profiles of livers from male C57BL/6J mice exposed to prenatal vitamin D deficiency through a maternal dietary intervention model. We found that prenatal vitamin D deficiency increases the prevalence of histopathological changes in the liver, and alters its gene expression profile. Cell subtype proportion analysis showed that the liver of prenatal vitamin D deficiency alters non-parenchymal cells of the liver, specifically macrophages, a subset of endothelial cells, and dendritic cells. Our results indicate the long-term memory of prenatal vitamin D deficiency exposure in the adult liver, a potential contributor to offspring health risks.

Abstract
OBJECTIVES Preterm infants are at increased risk for vitamin D deficiency (VDD). We aimed to assess the adequacy of standardized vitamin D supplementation protocol in very low birth weight (VLBW) infants. Additionally, vitamin D status of mother/infant couples and the associations between vitamin D status at birth and morbidities of the infants were investigated. METHODS In this single-center, prospective cohort study blood samples were collected from 55 mothers just before delivery and from their infants at birth and on the 30th day of life (DOL) for 25 hydroxy vitamin D (25OHD) measurements. Vitamin D was initiated in dose of 160 IU/kg by parenteral nutrition on the first DOL and oral vitamin D supplementation (400 IU/day) was administered when enteral feedings reached 50% of total intake or on the 15th DOL. RESULTS The median 25OHD levels of the infants were 16.12 (9.14-20.50) in cord blood and 36.32 (31.10-44.44) in venous blood on the 30th DOL (p<0.01). In 98% of the VLBW infants 25OHD reached sufficient levels on the 30th DOL. None of the mothers had sufficient vitamin D levels (25OHD >30 ng/mL). Maternal 25OHD levels were correlated with the 25OHD levels of the infants in cord blood (r=0.665, p<0.001). There was a significant difference in mean cord 25OHD levels between winter (13.65 ± 5.69 ng/mL) and summer seasons (19.58 ± 11.67 ng/mL) (p=0.021). No association was found between neonatal morbidity and vitamin D status. CONCLUSIONS The results clearly show that by utilizing the current supplementation protocol, the majority of VLBW infants with deficient/insufficient serum 25OHD levels reached sufficient levels on the 30th DOL. Furthermore, vitamin D levels in mother/infant couples were found to be highly correlated.

Abstract
OBJECTIVE To evaluate the relationship between 25-hydroxy vitamin D (25(OH)D) levels and disease severity in hospitalized COVID-19 positive pregnant women. METHODS The COVID-19 (+) pregnant women (confirmed by PCR test) were classified as asymptomatic, mild symptomatic, and severe disease according to their symptoms and laboratory results. Severe COVID-19 criteria were respiratory symptoms and/or findings. The following laboratory results were considered as poor prognostic factors: the number of lymphocytes <800/µl and/or CRP value >10 times the upper limit of the normal range and/or ferritin value >500 ng/ml and/or D-Dimer value >1000 µg/l. The patients were divided into two groups; asymptomatic or mild symptomatic group (Group 1), and severe disease and/or poor prognostic factor group (Group 2). The 25(OH)D levels were compared between groups. ROC curve analysis was used to analyze the cutoff value for vitamin D to predict the severity of COVID-19. RESULTS 25(OH)D levels were found to be statistically significantly lower in group 2 (15.5 (10.25) ng/ml in Group 1, 13 (12) ng/ml in Group 2, p = .010). The 25(OH)D level under 14.5 ng/ml was associated with severe COVID-19 and/or poor prognostic factors (p = .010). The risk of severe COVID-19 and/or having poor prognostic factors was 1.87 times higher among pregnant women who had 25(OH)D levels below 14.5 ng/ml. This value was found to have 54.1% sensitivity and 61.3% specificity in predicting severe COVID-19 and/or poor prognostic laboratory findings in pregnant women. CONCLUSION There is a relationship between vitamin D status and the severity of COVID-19 in pregnant women. During the pandemic period, vitamin D supplementation for pregnant women should gain more importance.

Abstract
BACKGROUND/AIM Acute bronchiolitis is mostly caused by viral agents in children under 2 years of age. The disease mostly has a mild clinical course however severe cases are not uncommon. Vitamin D is known to exert immune-regulatory functions. We aimed to examine the association between the clinical severity of acute bronchiolitis and serum vitamin D levels in infants. MATERIALS AND METHODS A total of 182 children with acute bronchiolitis were prospectively enrolled. The disease severity was assessed using the Modified Tal Scoring System and their vitamin D levels were evaluated. RESULTS Vitamin D deficiency or insufficiency was as high as 47.8% in infants with bronchiolitis. Infants with low vitamin D levels comprised a significantly larger proportion of patients with severe bronchiolitis (p = 0.002). Infants admitted to intensive care unit had significantly higher degrees of vitamin D deficiency or insufficiency (p < 0.001). CONCLUSION Vitamin D deficiency is closely linked with severe bronchiolitis and the need for intensive care unit admission in infants. We believe that assessment of vitamin D levels in infants prior to bronchiolitis season and appropriate supplementation may have a protective effect against severe bronchiolitis.

Abstract
BACKGROUND: Vitamin D deficiency in neonates is associated with neonatal sepsis incidence. It is also significantly correlated to the increased risk in the outcomes of sepsis, such as mortality, length of hospital stay, and use of ventilatory support.
AIM: The aim of the study is to observe the relationship between Vitamin D levels and clinical outcomes of sepsis in the neonatal unit.
METHODS: An analytical cross-sectional study was conducted to neonates in neonatology Haji Adam Malik hospital from June 2019 to February 2020. A Chi-square test was carried out to observe the relationship between Vitamin D levels and sepsis outcomes, and a Mann-Whitney test was done to assess the significance between Vitamin D levels and length of hospital stay.
RESULTS: Among 41 full-term and pre-term neonates, there were 75.6% (31/41) neonates with Vitamin D deficiency, while 24.4% (10/41) had normal Vitamin D levels and did not suffer from deficiency. The relationship of Vitamin D levels with mortality, use of ventilatory support, length of stay, and blood culture was p = 0.660 (95% confidence interval [CI] = 0.810–1.677), p = 0.013 (p < 0.05), p = 0.940 (median 21 days), and p =0.712 (95% CI = 0.623–1.353), respectively.
CONCLUSION: Vitamin D deficiency had a significant relationship with ventilatory support requirement as one of the sepsis outcomes in neonates.

Abstract
There is an increasing number of people who go vegetarian. Some young parents also switch
to this diet. The safety of vegetarian diets, especially vegan diets, is very important, especially
during pregnancy. Unfortunately, reference publications do not provide coherent data on the
safety of vegetarian diets during pregnancy. On the one hand, the vegan diet has advantages
because it reduces the risk of heart disease and gestational diabetes. On the other hand,
vegetarians/vegans should be aware of potential deficiencies of some nutrients (iron, zinc,
vitamin B12, vitamin D, omega-3 fatty acids, calcium, iodine) and the clinical consequences
for the fetus. For example, iron deficiency may affect cognitive abilities, behavior, intelligence
and increase the risk of preterm birth and low birth weight of infants. Plant food contains
non-haem iron with variable absorption. Therefore, the vegan diet should include nutrients
increasing the bioavailability of iron, e.g. ascorbic acid, carotene and retinol. Due to the fact
that animal food is the main source of vitamin B12, vegans are at a very high risk of vitamin
B12 deficiency, which will affect the infant’s weight at birth. Low level of vitamin D, which is
prevalent in animal food, is the most common deficiency among vegans and lacto-ovo vegetarians.
This vitamin prevents gestational diabetes, reduces insulin resistance and guarantees
normal function of the musculoskeletal system. Zinc deficiency during pregnancy may lead to
preterm birth, neural tube defects or even miscarriage. In view of the clinical consequences
of potential deficiencies of nutrients, the vegetarian/vegan diet should be well balanced.

Abstract
INTRODUCTION Vitamin D deficiency (VDD) is rampant in neonates. Recommendations for supplementation are variable. METHODS An observational study was done on less than 32 weeks of very low birth weight neonates to find prevalence of VDD (<20 ng/ml) at baseline; at 38 ± 2 weeks post-menstrual age (PMA) after daily intake of 800 IU vitamin D (vit D). Secondary objectives were to find determinants of VDD, to compare growth in deficient; vit D sufficient (VDS) neonates; to find vit D toxicity. RESULTS Of 83 neonates, 81 (97.6%) were VDD at baseline and 5 (6%) at 38 ± 2 weeks PMA. Determinants for VDD at baseline were inadequate maternal sun exposure (p < 0.001) and vit D supplementation (p = 0.007). Factors for VDD at 38 ± 2 weeks PMA were male gender (p = 0.049), morbidities (p = 0.006), ventilation >24 h (<0.001), sepsis (p = 0.032), caffeine (p ≤ 0.001) and missed supplements (p < 0.001). Weight and length gain of VDD to VDS neonates were (6.70 ± 2.40 to 8.96 ± 2.21 g/day); (0.82 ± 0.34 to 1.08 ± 0.37 cm/week), respectively (p < 0.001). Head circumference gain (cm/week) of VDS; VDD neonates was 0.58 ± 0.09; 0.54 ± 0.06 (p = 0.054), respectively. No neonates developed vit D toxicity. CONCLUSIONS In preterm VLBW neonates, the prevalence of VDD was 97.6% but decreased by >90% at 38 ± 2 weeks with a daily intake of 800 IU vit D. Inadequate maternal vit D intake and sun exposure determined low baseline vit D status of neonates. Male gender, morbidities, ventilation, sepsis, caffeine, missed vitamin D supplements were determinants of poor vit D status at follow-up. Weight gain and length increments were more in the VDS group.

[PMID: 32815629 PMCID: PMC7729540 DOI: 10.1111/mcn.13028] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/12/2019] [Revised: 04/25/2020] [Accepted: 04/27/2020] [Indexed: 12/11/2022]
Abstract
In Pakistan, there is limited evidence for the levels and relationship of 25 (OH) Vitamin D (25(OH)D) status in pregnant women and their newborns, while the association between maternal 25(OH)D and newborn anthropometric measurements remains unexplored. Sociodemographic data were collected from 213 pregnant mothers during their visit to a tertiary care hospital at the time of childbirth. Anthropometric measurements were performed on all mothers and their newborns and blood samples collected from both for 25(OH)D levels. Participants were classified into two groups according to their 25(OH)D status: sufficient (25(OH)D ≥50 nmol L-1 ) and deficient (25(OH)D <50 nmol L-1 ). Simple and multiple regression models were used for analysis. Among 213 pregnant women, prevalence of 25(OH)D deficiency was 61.5%, and their newborn was 99.5% (mean 25(OH)D levels: 46.3 [11.3] and 24.9 [5.4] nmol L-1 , respectively). Maternal sociodemographic characteristics were similar between 25(OH)D deficient and sufficient mothers, whereas newborn 25(OH)D levels were significantly lower in the former (22.60 [4.53] vs. 27.67 [3.82] nmol L-1 , respectively, P < 0.001). There was a strong positive association between maternal and newborn 25(OH)D levels (r, 0.66; r2 , 43%, B [SE], 0.3 [0.02]; P < 0.001). Association of maternal 25(OH)D levels with newborn weight, length and head circumference was not significant (all P > 0.05). Our study shows a high prevalence of 25(OH)D deficiency in pregnant women and their newborns and a strong positive association between maternal and newborn 25(OH)D levels. Findings of this study indicate the importance of maintaining sufficient 25(OH)D levels during pregnancy.

Serum 25 Hydroxyvitamin D Levels During Pregnancy in Women with Asthma: Associations with Maternal Characteristics and Adverse Maternal and Neonatal Outcomes. Nutrients 2020; 12:nu12102978. [PMID: 33003370 PMCID: PMC7600161 DOI: 10.3390/nu12102978] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2020] [Revised: 09/24/2020] [Accepted: 09/28/2020] [Indexed: 12/02/2022] Open
Abstract
Low 25-hydroxyvitamin D (25(OH)D) levels are common in pregnancy and associated with adverse maternal/neonatal outcomes. In pregnant women with asthma, this study examined the association of lifestyle- and asthma-related factors on 25(OH)D levels and maternal/neonatal outcomes by vitamin D status. Serum 25(OH)D was measured at 16 and 35 weeks gestation in women with asthma (n = 103). Body mass index (BMI), gestational weight gain (GWG), smoking status, inhaled corticosteroid (ICS) use, asthma control, airway inflammation, and exacerbations, and maternal/neonatal outcomes were collected. Baseline and change (Δ) in 25(OH)D were modelled separately using backward stepwise regression, adjusted for season and ethnicity. Maternal/neonatal outcomes were compared between low (25(OH)D < 75 nmol/L at both time points) and high (≥75 nmol/L at one or both time points) vitamin D status. Fifty-six percent of women had low vitamin D status. Obesity was significantly associated with lower baseline 25(OH)D (Adj-R2 = 0.126, p = 0.008); ICS and airway inflammation were not. Excess GWG and season of baseline sample collection were significantly associated with Δ25(OH)D (Adj-R2 = 0.405, p < 0.0001); asthma-related variables were excluded (p > 0.2). Preeclampsia was more common in the low (8.6%) vs. high (0%) vitamin D group (p < 0.05). Obesity and excess GWG may be associated with gestational 25(OH)D levels, highlighting the importance of antenatal weight management.

Abstract
Some studies showed that the polymorphisms of vitamin D receptor (VDR) gene were associated with pulmonary diseases. However, the relationship between the VDR variations and susceptibility to coal worker's pneumoconiosis (CWP) remains unclear. The study aimed to determine the associations between VDR polymorphisms and susceptibility to CWP in Chinese Han population. The study involved 340 CWP patients and 312 healthy controls. The VDR polymorphisms were determined by DNA sequencing, and serum 25(OH)2D levels were detected by Ultra High-Performance Liquid Chromatography-Tandem Mass Spectrometry. The results showed that the VDR gene ApaI T allele increased the risk of CWP (OR = 1.486, 95% CI = 1.125-1.963, P = 0.006) and ApaI GT genotype as well as TT genotype increased the risk of CWP (GT vs. GG, OR = 1.461, 95% CI = 1.048-2.038, P = 0.025; TT vs. GG, OR = 2.673, 95% CI = 1.017-7.025, P = 0.039). Five haplotypes were identified and we found that the TGGT haplotype was associated with a lower risk of CWP (OR = 0.755, 95% CI = 0.603-0.946, P = 0.014). Meanwhile, multifactor dimensionality reduction analysis showed that the interaction between ApaI and exposure was the strongest, followed by TaqI and then BsmI. The study also found that the serum 25(OH)2D mean levels of the case group were significantly lower than that of the control group, and the serum 25(OH)2D mean levels of ApaI homozygous mutant and heterozygous mutant subjects were lower than that of the wild homozygosity, respectively (P < 0.001). The results suggested that ApaI T allele and GT or TT genotype and lower 25(OH)2D levels were increased the risk of CWP in Chinese Han population.

Abstract
Background Recent study found that vitamin D before conception was considered as a potential additional determinant for achieving pregnancy and live births. The study aimed to evaluate the serum 25 hydroxyvitamin D (25(OH)D) levels and its affecting factors among preconception fertile women. Methods This cross-sectional study enrolled 410 women aged 22–44 years who attended a preconception genetic counseling clinic from January 2018 to May 2019. Sociodemographic characteristics and reproductive history of women were collected, and height and weight were measured. Serum 25(OH)D concentration was assayed with chemiluminescence immunoassay. Descriptive statistics were used to examine serum 25(OH)D concentration, and socio-demographic characteristics and reproductive history among preconception women. Determinants of vitamin D deficiency and its affecting factors were assessed using χ2 test and logistic regression. Results Findings showed 84.4% of women had serum 25(OH)D concentration below 20 ng/mL. Women working indoors as well as without a history of childbirth had significantly lower 25(OH)D levels compared with those non-working individuals and having delivered a previous child (both P < 0.05). The 25(OH)D levels were the lowest in winter among that in spring, summer, and autumn (all P < 0.001). Women in winter have significantly elevated OR of 5.00 (95%CI 1.75–14.25) to develop vitamin D deficiency. Seasonal variation in serum 25(OH)D levels was not present in non-working individuals and women aged 31–44 years. Conclusions Vitamin D deficiency is common among preconception women especially nulliparous women and working women, which propose to screen serum 25(OH)D on preconception evaluation and emphasize need vitamin D supplements and get sunshine exposure.

Abstract
Background The prevalence of vitamin D deficiency and insufficiency is extremely high in pregnant women worldwide. However, the association between single nucleotide polymorphisms (SNPs) in vitamin D metabolic pathway genes and 25‐hydroxyvitamin D (25(OH)D) concentration among Chinese pregnant women is seldom reported. The risk of adverse neonatal outcomes due to maternal vitamin D deficiency has not been well investigated. Methods A total of 815 pregnant women and 407 infants were enrolled in this study. Serum 25(OH)D concentration was detected. DNA was extracted from the maternal blood for genotyping genetic SNPs in vitamin D pathway. An XGBoost model was established based on SNPs combined with external variables. Results Mean serum 25(OH)D level was 15.67 ± 7.98 ng/mL among the pregnant women. Seventy‐five percent of pregnant women had 25(OH)D deficiency in China. SNPs of GC (rs17467825, rs4588, rs2282679, rs2298850, and rs1155563) were significantly associated with maternal 25(OH)D concentration. The influence of variants of rs17467825, rs4588, rs2282679, and rs2298850 on maternal 25(OH)D might be modified by vitamin D supplementation and sunshine exposure. An XGBoost model was established for monitoring 25(OH)D status in pregnant women and provided clinical advice to reduce the risk of 25(OH)D deficiency. Mothers with 25(OH)D deficiency hinted a risk for macrosomia. Conclusion A high prevalence of vitamin D deficiency in China has been confirmed. A clinical model was established to guide pregnant women to supplement vitamin D according to genotype. Furthermore, we suggest the effect of maternal vitamin D status on the risk of macrosomia.

Abstract
BACKGROUND Striae gravidarum (SG) are a form of scarring on the skin observed during pregnancy and an important cosmetic problem. Vitamin D plays an important role in the skin. AIMS To assess the association between serum 25-hydroxyvitamin D (25(OH)D) levels and the presence and severity of SG in primigravid women. METHODS The study included 91 primigravid women at the gestational age of 36-41 weeks. Patients were examined and divided into two groups with respect to whether they had SG or not. Striae were scored using the numerical scoring system of Atwal et al. The serum 25(OH)D levels were evaluated. RESULTS While 55 patients (60.5%) had SG, 36 (39.5%) did not. The mean serum 25(OH)D level of women with SG was 17.69 ± 9.81 ng/mL and of women without SG was 21.18 ± 11.71 ng/mL. There was no statistically significant difference between two groups (P = .144). Multivariate logistic regression analysis has shown that women who have normal values of serum 25(OH)D (≥30 ng/mL) have a lower risk of having SG than women who have scarce levels of serum 25(OH)D (<20 ng/mL) after adjusting for confounding factors (adjusted odds ratio = 0.18, 95% confidence interval: 0.04-0.72, P = .015). According to the results of the linear-by-linear test, the association between serum 25(OH)D levels and the severity of SG was not found significant (P = .82). CONCLUSIONS This is the first study to show that having normal values of serum 25(OH)D is linked to a lower risk of having SG than scarce levels. Therefore, management of vitamin D deficiency might help prevent SG in primigravid women.

Abstract
Metabolic syndrome is a disorder of energy use and storage, which is characterized by central obesity, dyslipidemia, and raised blood pressure and blood sugar levels. Maternal 25-hydroxyvitamin D deficiency is known to cause metabolic changes, chronic disease, and increased adiposity in adulthood. However, the underlying mechanism of induced metabolic syndrome (MetS) in the offspring in vitamin D deficient pregnant mothers remains unclear. We identified that maternal 25-hydroxyvitamin D deficiency enhances oxidative stress, which leads to the development of MetS in the mother and her offspring. Further, immunohistochemical, Western blotting, and qRT-PCR analyses revealed that maternal 25-hydroxyvitamin D deficiency inhibited the activation of the Nrf2/carbonyl reductase 1 (CBR1) pathway in maternal placenta, liver, and pancreas, as well as the offspring's liver and pancreas. Further analyses uncovered that application of 25-hydroxyvitamin D activated the Nrf2/CBR1 pathway, relieving the oxidative stress in BRL cells, suggesting that 25-hydroxyvitamin D regulates oxidative stress in offspring and induces the activation of the Nrf2/CBR1 pathway. Taken together, our study finds that maternal 25-hydroxyvitamin D deficiency is likely to result in offspring's MetS probably via abnormal nutrition transformation across placenta. Depression of the Nrf2/CBR1 pathway in both mothers and their offspring is one of the causes of oxidative stress leading to MetS. This study suggests that 25-hydroxyvitamin D treatment may relieve the offspring's MetS.

Abstract
Hypovitaminosis D is prevalent worldwide; however, analytical bias in the measurement of circulating 25-hydroxyvitamin D (25(OH)D) concentrations may affect clinical treatment decisions and research. We performed parallel plasma 25(OH)D analyses using the Abbott Architect i2000 chemiluminescent immunoassay (CIA) and liquid chromatography–tandem mass spectrometry (LC–MS/MS) for paired samples from the same infants at 3 (n = 69), 6 (n = 79) and 12 months (n = 73) of age. To test agreement, we used Lin’s concordance correlation coefficient and corresponding 95% confidence interval, Bland–Altman’s limits of agreement, and Bradley–Blackwood (BB) test. Agreement was high at 3 months (coefficient between difference and mean −0.076; BB F = 0.825; p = 0.440), good at 12 months (−0.25; BB F = 2.41; p = 0.097) but missing at 6 months of age (−0.39; BB F = 12.30; p < 0.001). Overall, 18 infants had disparate results based on the cut-off point for vitamin D deficiency (25(OH)D < 50 nmol/L), particularly at three months, with seven (10%) infants deficient according to CIA but not LC–MS/MS, and four (6%) deficient by LC–MS/MS but not CIA. To our knowledge, this is the first study to show that the reported 25(OH)D concentration may be influenced by both age and assay type. Physicians and researchers should be aware of these pitfalls when measuring circulating 25(OH)D concentrations in infants and when developing treatment plans based on measured vitamin D status.

Yu M, Liu X, Li J. Factors Influencing Vitamin D Levels in Neonatal Umbilical Cord Blood: A Two-Center Study From Tibet and Shenyang. Front Pediatr 2020; 8:543719. [PMID: 33330264 PMCID: PMC7719748 DOI: 10.3389/fped.2020.543719] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/18/2020] [Accepted: 10/26/2020] [Indexed: 02/02/2023] Open
Abstract
Objective: To investigate the factors influencing the levels of vitamin D (vitD) in the umbilical cord blood of neonates born in Naqu, Tibet (4,500 m above sea level), and Shenyang, Liaoning Province (500 m above sea level). Methods: This prospective study was conducted from June 2017 to October 2018 in Naqu (the plateau group) and Shenyang, (the non-plateau group). Healthy mothers that gave birth to healthy neonates of >2,000g after 38 weeks' gestation were enrolled in the study, as were their neonates. After separation of serum from the umbilical cord and mothers for routine biochemical tests, discarded samples were remained for analyses of vitD, calcium, phosphorus, alkaline phosphatase (ALP) and parathyroid hormone (PTH). Questionnaires were developed covering the demographic characteristics and possible risk factors for neonatal vitD deficiency of mothers. Statistical analysis was performed to identify associations between the calcium, phosphorus, ALP, PTH, maternal factors and neonatal vitD levels. Results: In total, 295 neonates and 225 mothers were enrolled in the study. VitD deficiency was common in neonates and mothers. The risk of vitD deficiency was higher in the plateau group than in the non-plateau group. The mean levels of 25-hydroxy vitD (25(OH)D) in mothers and neonates from the plateau group were 8.49 ± 4.12 ng/mL and 10.17 ± 5.07 ng/mL, respectively. Such levels were significantly lower than those in the non-plateau group (19.77 ± 9.57 ng/mL and 23.93 ± 11.01 ng/mL, respectively). The vitD levels of neonates and mothers were highest in the summer and lowest in the winter. Cord blood vitD was positively correlated with the vitD levels in mothers' serum (r = 0.75, P < 0.05). Increased PTH levels in mothers and decreased cord blood calcium levels were risk factors for neonatal vitD deficiency. A lack of vitD supplementation during pregnancy was associated with an 8.91-fold higher probability of neonatal vitD deficiency (OR = 8.91, 95% CI = 1.521-9.429, P < 0.001). Conclusions: The levels of neonatal and maternal vitD in the plateau group were generally lower than those in the non-plateau group. VitD supplementation during pregnancy could effectively reduce the risk of vitD deficiency in neonates.

Higher serum alkaline phosphatase activity in infants born to vitamin D-deficient mothers. Arch Osteoporos 2019; 14:102. [PMID: 31650259 DOI: 10.1007/s11657-019-0651-9] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/30/2018] [Accepted: 09/03/2019] [Indexed: 02/03/2023]
Abstract
UNLABELLED Our research shows that the newborns of vitamin D-deficient mothers have higher serum alkaline phosphatase (ALP) activity compared with those of vitamin D-non-deficient mothers, which is likely related to increased bone turnover rather than just being a marker for bone formation. This has a potential negative impact on fetal bone development and subsequent skeletal growth. PURPOSE/INTRODUCTION Low maternal serum 25-hydroxy vitamin D (25(OH)D) level during pregnancy contributes to vitamin D deficiency in infants at birth, which is associated with multiple potential adverse effects on fetal skeletal mineralization and growth. We studied the relationship between maternal 25(OH)D level and newborn serum alkaline phosphatase activity (ALP) at term. METHODS In this prospective cross-sectional hospital-based study, venous blood samples of healthy pregnant mothers were drawn to measure 25(OH)D levels within 6 h of delivery. Cord blood samples were examined for calcium, phosphorus levels, and ALP activity immediately after birth. In addition, we also recorded the newborns' anthropometric measurements. RESULTS Seventy-two percent (n = 108/150) of mothers in our study were vitamin D-deficient (serum 25(OH)2D < 25 nmol/l). In a multivariate logistic regression model, young maternal age (odds ratio (OR) = 0.94, 95% CI 0.88-0.99, p = 0.04) and increased weight (OR = 1.03, 95% CI 1.01-1.07, p = 0.02) as well as decreased milk intake (OR = 0.31, 95% CI 0.13-0.74, p = 0.009) were all significantly associated with maternal vitamin D deficiency. ALP activity was significantly higher in newborns of vitamin D-deficient compared with vitamin D-non-deficient mothers (median = 176 (IQR = 139-221) and 156 (IQR = 132-182), respectively, p = 0.04). A significant inverse correlation (Pearson's coefficient = - 0.18, p = 0.03) was observed between maternal 25(OH)D levels and babies' ALP activities. This association persisted in a multivariate logistic regression model (OR = 3.46, 95% CI 1.18-10.18, p = 0.024). CONCLUSIONS Our findings indicate that newborns of vitamin D-deficient mothers have higher serum ALP activity than those of non-deficient mothers, which might be related to increased bone turnover rather than just being a marker for bone formation. This could have a potential negative impact on fetal bone development and subsequent skeletal growth.

Abstract
Objective: To evaluate the maternal and neonatal 25-hydroxyvitamin D [25(OH)D] levels and the effect of 25(OH)D levels on the development of neonatal sepsis. Methods: This prospective study was performed in the neonatal intensive care unit of Medicine Hospital/Biruni University between November 2017 and September 2018. Fifty one term infants with sepsis group and 56 term infants with control group were included in this study. Blood samples for whole blood count, CRP, Ca, P, ALP, 25(OH)D and culture were obtained from all neonates. Results: Mean vitamin D levels for the neonates and their mothers were found to be 12.4±8.5 ng/ml and 13±8.7 ng/ml, respectively. There was a significant correlation between maternal and newborn 25(OH)D levels (r=0.72, p<0.01). The number of the newborns with vitamin D deficiency was significantly higher in the sepsis group (n=31, 60.8%) than in the control group (n=30, 53.6%; p=0.00), corresponding to significantly lower levels of vitamin D in the sepsis group (11±5.5 ng/ml vs. 13.8±10.6 ng/ml; p=0.012). Similarly, maternal vitamin D levels was significantly lower in the sepsis group than in the control group (10.8±5.6 ng/ml vs. 14.9±10 ng/ml; p=0.001). Conclusion: Our findings suggest that there may be an association between vitamin D deficiency and neonatal sepsis

Abstract
Background An adequate maternal vitamin D (vitD) intake is rarely achieved in actual practice. The aim of this study was to assess maternal factors associated with neonatal vitD deficiency. Methods This is a single-institution prospective case-control study. Consecutive single-birth neonates admitted between September 2014 and February 2015 were prospectively enrolled. Serum 25-hydroxyvitamin D (25(OH)D) concentrations were measured by spectrometry. The associations between neonatal vitD deficiency (defined as 25(OH)D <15 ng/mL) and several maternal characteristics, including body mass index (BMI) at delivery, education, health insurance status, birth season, sun exposure time, egg consumption, and vitD supplementation during pregnancy, were examined using multivariable logistic regression and their respective odds ratios (ORs) reported. Results A total of 125 mother-infant dyads were enrolled, with a gestational age of 36.8±2.7 weeks. Fifty-six percent (70/125) of the neonates had vitD deficiency. Maternal factors that were significantly associated with vitD deficiency included winter birth, insufficient sun exposure time, high maternal BMI at delivery, insufficient egg consumption, insufficient vitD supplementation during pregnancy, and disadvantaged health insurance. Disadvantaged insurance status and insufficient vitD supplementation during pregnancy were the two most influential factors of neonatal vitD deficiency, with an OR of 7.5 (95% confidence interval [CI], 2.0-37.6) and 7.0 (95% CI, 2.7-20.7), respectively. Conclusions Neonatal vitD deficiency is very rampant. An individualized vitD supplementation strategy may be developed by taking into consideration pregnant women's socioeconomic status and lifestyles.

Abstract
BACKGROUND Vitamin D levels may differ between migrant and non-migrant populations, especially among non-western immigrants living in a country with limited sun exposure such as Germany. This study examined serum vitamin D concentration and associated factors among Berliners with and without Turkish background. METHODS Two samples (with and without Turkish roots) were recruited in the inner city of Berlin for a cross-sectional study assessing serum vitamin D concentration. Linear regression analyses were used to examine sociodemographic, lifestyle and medical factors associated with serum vitamin D levels. RESULTS In the analyses, we included 537 subjects (39% men and 61% women, age 43.2 ± 12.5 (mean ± standard deviation) years) with and 112 without Turkish background (46% men and 54% women, age 46.7 ± 14.6 years). The Turkish sample had lower mean (95%-Confidence Interval) vitamin D levels than the non-Turkish sample: 22.7 nmol/L (21.5;23.9) vs 34.7 nmol/L (31.9;37.5), p < 0.001. In the Turkish female subgroup, veiled women had considerably lower levels than unveiled women: 14.4 nmol/L (11.5;17.3) vs 24.9 nmol/L (23.1;26.7), p < 0.001. Multivariable regression analysis revealed that among the Berliners of Turkish descent, being active less than 150 min per day, and being overweight/obese were independently associated with a lower vitamin D concentration. In the non-migrant sample besides being overweight and obese, female sex was associated with lower vitamin D concentrations. CONCLUSIONS Serum vitamin D levels were considerably low in Berliners of Turkish descent, and especially in veiled women. Potentially modifiable factors of low vitamin D levels were high BMI and low physical activity. These findings should be considered in the development of future public health strategies for subpopulations with Turkish migration background.
