Abstract
BACKGROUND Sepsis is one of the main causes of death in newborns worldwide. Vitamin D levels during fetal and neonatal periods have a significant role in the development of the immunological system. The study aims to evaluate the association between vitamin D levels and the risk of early-onset neonatal sepsis in full-term neonates in a developing country. METHODS This case-control study was conducted at the Neonatal Intensive Care Units (NICUs) of Kasr Alainy Hospital, Cairo, Egypt. The study was composed of two groups; the sepsis group involved full-term neonates appropriate for gestational age with sepsis-related clinical signs. The control group included newborns with no signs of clinical/laboratory infection within 72 h of life. Blood samples were collected on admission during the first three days of life in both groups for the measurement of 25-hydroxyvitamin D levels, Complete Blood Count (CBC), C reactive protein (CRP), and blood culture. RESULTS Forty-five newborns with clinical and laboratory findings of early-onset neonatal sepsis within 72 h of life were enrolled, and the control group included forty-five newborns with no evidence of sepsis. Vitamin D levels in the sepsis group were significantly lower than in the control group. Apgar score at the first minute was significantly lower in the sepsis group. 57.8% of neonates with sepsis had positive blood cultures. There was a statistical difference between deficient, insufficient, and sufficient vitamin D levels regarding the duration of the NICU stay, which was longer in neonates with deficient vitamin D levels. CRP was significantly higher in neonates with deficient vitamin D levels. The area under the receiver operating characteristic curve for serum vitamin D in the prediction of neonatal sepsis was 0.76 at a cutoff < 19.7(ng/ml). CONCLUSION In the current study, full-term newborns with EOS had considerably lower vitamin D levels than healthy controls. Through appropriate vitamin supplementation of the mothers during pregnancy, it could be possible to ensure adequate vitamin D levels for newborns. This may contribute to the reduction of the risk of EOS, together with the other well-known preventive measures (i.e. breastfeeding and intrapartum antibiotic prophylaxis).

Abstract
OBJECTIVE The aim of the study is to investigate the relation of neonatal and maternal vitamin D and late-onset sepsis (LOS). STUDY DESIGN One-hundred twenty term neonates along with their mothers were enrolled in this case-control study. Sixty neonates who were admitted in the neonatal intensive care unit by LOS and had not been previously admitted for last 48 hours and did not receive antibiotics or vitamin D were enrolled as cases (sepsis) group. On the other hand, 60 healthy term neonates were referred as control group. Maternal and neonatal serum 25-OH vitamin D levels were assessed in both the cohorts. RESULTS Maternal and neonatal 25-OH vitamin D levels in cases (17.2 and 16.1 ng/mL, respectively) were significantly lower than in controls (22.7 and 21 ng/mL, respectively) p = 0.001. In the study group, the neonatal 25-OH vitamin D was negatively correlated with C-reactive protein and length of hospital stay (r = -0.616 and -0.596, respectively) p <0.001 for both. With a cut-off value of 12.9 ng/mL, the specificity and positive predictive value of neonatal vitamin D were 83.3 and 74.4%, respectively. The odds ratio was 1.088 (95% CI = 1.034-1.144)) for LOS in vitamin D-deficient neonates. CONCLUSION Neonates with higher vitamin D level are at lower risk of LOS than those with vitamin D deficiency. Maternal vitamin D correlates with neonatal vitamin D. These data suggest that maternal vitamin supplementation during pregnancy may lower the risk of LOS. KEY POINTS · Neonatal and maternal vitamin D deficiency increase risk of LOS.. · Neonatal vitamin D correlates with maternal vitamin D.. · Neonatal vitamin D is independent predictor for LOS..

Abstract
Patients with sepsis have a wide range of respiratory disorders that can be treated with oxygen therapy. Experimental data in animal sepsis models show that oxygen therapy significantly increases survival, while clinical data on the use of different oxygen therapy protocols are ambiguous. Oxygen therapy, especially hyperbaric oxygenation, in patients with sepsis can aggravate existing oxidative stress and contribute to the development of disseminated intravascular coagulation. The purpose of this article is to compare experimental and clinical data on oxygen therapy in animals and humans, to discuss factors that can influence the results of oxygen therapy for sepsis treatment in humans, and to provide some recommendations for reducing oxidative stress and preventing disseminated intravascular coagulation during oxygen therapy.

Abstract
OBJECTIVE This study explored the status of serum vitamin D in hospitalized full-term neonates at a tertiary hospital in eastern China. METHODS A prospective study was conducted among 471 hospitalized full-term neonates at the Children's Hospital of Soochow University between January 1 and June 20, 2020. Perinatal clinical data, serum 25-hydroxyvitamin D (25(OH)D3), laboratory examinations, serum calcium levels, and immune function were obtained and analyzed. We explored and analyzed the risk factors for vitamin D insufficiency or deficiency, and we also attempted to determine correlations between vitamin D and its influence on immunity. RESULTS The mean serum 25(OH)D3 was 33.65±6.07ng/ml.The prevalence of vitamin D insufficiency was 28.24%,vitamin D sufficiency was 71.76%, there was no vitamin D deficiency. The serum 25-(OH)D3 in singleton neonate was higher than twins or multiple infants (t = -10.918, P = 0.000). The serum 25-(OH)D3 were higher in neonates who born in spring and summer than in winter (H = 13.443, P = 0.001). The serum 25-(OH)D3 in appropriate for gestational age (AGA) and large for gestational age (LGA) neonates were higher than small for gestational age (SGA) (H = 7.686, P = 0.021). The serum 25-(OH)D3 were higher in neonates whose mothers had no underlying diseases than those with certain immunological and infectious diseases (F = 12.417, P = 0.000). The serum 25-(OH)D3 in neonates whose mothers had none or one perinatal complication were higher than those with two or more (F = 13.299, P = 0.000). The neonates with eosinophils ≤5% or normal platelet counts or serum Ca++ ≥0.9 mmol/L have higher serum 25-(OH)D3. Neonates born in winter were at risk for vitamin D insufficiency, and the incidence of infectious pneumonia, sepsis, cytomegalovirus infection, and hypocalcemia in the vitamin D insufficiency group were higher than sufficiency group (P < 0.05). The serum CD3+, CD3+CD4+, and IgA levels in vitamin D sufficiency neonates were significantly higher than those in insufficiency group (P < 0.05). CONCLUSION The prevalence of vitamin D insufficiency was 28.24%, and birth in winter was a risk factor for vitamin D insufficiency in hospitalized full-term neonates in Suzhou area. Neonates with infectious pneumonia, sepsis, cytomegalovirus infection, and hypocalcemia exhibited a high risk of vitamin D insufficiency. The serum CD3+, CD3+CD4+, and IgA levels in neonates with vitamin D insufficiency were lower.

Abstract
BACKGROUND Sepsis leads to the high mortality in critically ill infants and children. It is still controversial whether vitamin D deficiency was associated with the incidence of sepsis. Thus we designed the systematic review and meta-analysis. METHODS The Ovid Medline, Embase, PubMed, and Cochrane library were systematically searched until April 5, 2020. The 25 hydroxyvitamin D (25-OHD) level was recorded and set 20 ng/mL as cut-off in cohort study to divide the lower and higher 25-OHD group. The odds ratio (OR) and 95% confidence intervals (CIs) were calculated for comparing the impact of vitamin D deficiency on the incidence of sepsis in critically ill children. RESULTS A total of 27 studies were included with 17 case-control studies and 10 cohort studies. In those case-control studies, the maternal 25-OHD level and neonatal 25-OHD level in sepsis group was significant lower than non-sepsis group (P < .001). The percentage of severe vitamin D deficiency was significant higher in sepsis group comparing to non-sepsis group (odds ratio [OR] = 2.66, 95% CI = 1.13-6.25, P < .001). In those cohort studies, the incidence of sepsis in lower 25-OHD group was 30.4% comparing with 18.2% in higher 25-OHD level group. However, no statistical significant difference in terms of mechanical ventilation rate and 30-day mortality. CONCLUSION We demonstrated that critically ill infants and children with sepsis could have a lower 25-OHD level and severe vitamin D deficiency comparing to those without sepsis. Future studies should focus on the association of vitamin D supplement and the occurrence of sepsis in critically ill children.

Abstract
Vitamin D deficiency is a major public health concern of pregnant women and neonates worldwide, affecting more than half of neonates. Studies report inconsistent and inconclusive effects of vitamin D treatment on neonatal sepsis. This study aimed to provide conclusive evidence regarding the effect of maternal and cord blood vitamin D levels on neonatal sepsis. Data were retrieved from the electronic database (Web of Science, Scopus, CINAHL [EBSCOhost], ProQuest, EMBASE [Ovid], PubMed, Emcare, MEDLINE [Ovid], and gray literature sources [World cat, Mednar, Google scholar and Google]). Joanna Briggs Institute quality assessment tool was utilized for quality assessment while analysis was performed using Open Meta-analyst, Comprehensive Meta-analysis version 3.3.070, and Review Manager version 5.3 software. From the 18 studies included in the study, the overall prevalence of vitamin D deficiency among neonates was 61% (95% CI: 44.3, 77.7); 79.4% (95% CI: 71.6, 87.3) of neonates with sepsis were vitamin D deficient as were 43.7% (23.4, 63.9) of sepsis-free neonates. Neonates born from mothers with low vitamin D levels were at greater risk of developing neonatal sepsis with a weighed mean difference of -8.57 ng/ml (95% CI: -13.09, -4.05). Similarly, neonates with low cord vitamin D levels were at risk for neonatal sepsis with a mean difference of -8.78 ng/ml (95% CI:-11.58, -5.99). The incidence of EONS in full-term newborns was significantly associated with low maternal and cord blood vitamin D levels with weighed mean differences of -11.55ng/ml (95% CI: -17.63, -5.46) & -11.59 ng/ml (95% CI:-16.65, -6.53), respectively. Low levels of vitamin D both in the cord blood and maternal blood were significantly associated with neonatal sepsis. Hence, vitamin D supplementation for pregnant women and newborns could decrease neonatal sepsis.

Abstract
Vitamin D plays a critical role in calcium homeostasis and in the maintenance and development of skeletal health. Vitamin D status has increasingly been linked to non-skeletal health outcomes such as all-cause mortality, infectious diseases and reproductive outcomes in both humans and veterinary species. We have previously demonstrated a relationship between vitamin D status, assessed by the measurement of serum concentrations of the major vitamin D metabolite 25 hydroxyvitamin D (25(OH)D), and a wide range of non-skeletal health outcomes in companion and wild animals. The aims of this study were to define the host and environmental factors associated with vitamin D status in a cohort of 527 calves from Western Kenya which were part of the Infectious Disease of East African Livestock (IDEAL) cohort. A secondary aim was to explore the relationship between serum 25(OH)D concentrations measured in 7-day old calves and subsequent health outcomes over the following 12 months. A genome wide association study demonstrated that both dietary and endogenously produced vitamin D metabolites were under polygenic control in African calves. In addition, we found that neonatal vitamin D status was not predictive of the subsequent development of an infectious disease event or mortality over the 12 month follow up period.
