RESUMEN
Background: Congenital cytomegalovirus (CMV) infection is the leading cause of hearing loss and neurocognitive delay among children. Affected infants may be asymptomatic at birth and even pass their universal hearing screen. Early identification of CMV-infected infants will allow earlier detection, evaluation and management. The prevalence of congenital CMV infection in the developed world varies geographically from 0.6% to 0.7% of all deliveries and certain regions are at higher risk. The prevalence of congenital CMV is unknown for our region. Aim: The purpose of this study was to determine the prevalence of CMV infection among the neonatal population at an urban, tertiary hospital in northeast Florida which serves a large population of patients with low socioeconomic status to assess if universal screening program for congenital asymptomatic CMV infection can be determined. Methods: The study was submitted and approved by our Institutional Review Board. We tested the urine for CMV infection in 100 asymptomatic newborns (>32 weeks gestational age and >1,750â g weight at the time of delivery) delivered between June 2016 and July 2017. Results: Urine CMV was tested on 100 infants. One infant had a positive urine NAAT for CMV, making the prevalence of congenital CMV infection among asymptomatic newborns in our hospitals' population 1%. Conclusion: CMV prevalence in our setting of an urban, tertiary hospital is relatively consistent with the national average of all congenital CMV infections. A policy of universal screening for congenital CMV may be necessary.
RESUMEN
Melena neonatorum is not uncommon; it presents as bloody stool in newborns and is caused by ingestion of maternal blood. This case presents an infant who had multiple episodes of copious amount of blood in his stool starting at 10 min of life, which raised multiple concerns requiring further investigation. The alkali denaturation test confirmed that the blood was maternal; however, due to the amount of bloody stool and the time required for the alkali denaturation test to result, further workups such as abdominal radiograph and hemoglobin/hematocrit were completed to ensure nothing was overlooked. Our infant remained clinically stable under the newborn nursery care, and did not require a higher level of care. He was discharged with his mother at 52 Hours of Life with a follow-up appointment the next day with the Primary Care Physician.
RESUMEN
Objective: To show concordance between heel stick and placental blood sample pairs for newborns' pre-transfusion testing and to validate placental blood's tube and gel methodology. Methods: Placental samples were collected for pre-transfusion testing at birth from 78 singleton and twin newborns admitted to our Mother-Baby Unit to compare with the results of heel stick samples taken from same newborns. Gestational age ≥35 weeks, weight ≥2,000 g. The study was approved by the Institutional Review Board (IRB). Informed consent was obtained from newborn parents. ABO blood group, Rhesus factor (Rh), direct antiglobulin test (DAT), and antibody screen were performed. Ortho ProVue Analyzer was used for tube and gel methods. McNemar's test for paired categorical data was performed. Results: One hundred percent concordance in 78 pairs for ABO and Rh. Seventy-four pairs were tested for antibodies, 72 were both negative, 1 was both positive, and 1 gave discordant result. Ninety-nine percent concordance, p = 0.999. Sixty-five pairs were both DAT negative, seven were both DAT positive, and six gave discordant results. Ninety-two percent concordance, p = 0.68. Placental blood gave identical results comparing tube with gel methods. Conclusions: Placental blood is suitable for pre-transfusion testing and can replace heel sticks. Placental blood tube and gel methods are validated.
RESUMEN
OBJECTIVES: This study explored whether donor-milk supplementation increases breastfeeding exclusivity at 6 months of life. In 10/2015, we implemented donor milk for breastfed newborns who needed nutritional supplements for hypoglycemia, hyperbilirubinemia, and >8% weight loss at 40 h of life. STUDY DESIGN: We conducted a retrospective chart review on 122 qualified neonates admitted to newborn nursery at University of Florida Jacksonville 4 months before donor-milk implementation and 6 months after. RESULTS: 73 (60%) of the neonates received formula and 49 (40%) received donor milk. 39 (54%) in the formula group and 33 (46%) in the donor-milk group were surveyed after 6 months of life. Multivariate logistic regression showed that newborns who received donor milk had five times greater odds of being exclusively breastfed at 6 months of life. CONCLUSIONS: Donor milk as feeding supplementation for newborns is associated with increased exclusive breastfeeding at 6 months of life.

BACKGROUND: Published studies demonstrate that placental blood samples provide acceptable results for various laboratory tests, but these studies did not include pretransfusion testing. The aim of this study was to show concordance between heel stick and placental blood sample pairs for pretransfusion testing and to validate tube and gel method for placental samples. Using placental blood samples for pretransfusion testing potentially reduces the amount of blood collected from newborns for initial laboratory tests. STUDY DESIGN AND METHODS: Placental samples were collected for pretransfusion tests at birth from 32 newborns with less than 2000 g birthweight and less than 35 weeks to compare the results with the heel stick samples from the same newborns. ABO and D typing, direct antiglobulin test (DAT) with IgG, and antibody screen tests were performed on these sample pairs. For ABO and D typing both tube and gel methods were used to validate both methods for the placental samples. RESULTS: This study shows 100% concordance in 32 sample pairs for ABO, D, and DAT tests. Antibody screen results were compared on 29 sample pairs. All 28 sample pairs were concordant, but one placental blood sample was more sensitive to detect a weak maternal antibody than its corresponding heel stick sample was. CONCLUSION: The results of this study validated that placental blood samples can be used in place of heel stick samples and are suitable for pretransfusion testing. This study also validated ABO and D typing by tube and gel methods for placental samples.

OBJECTIVE: Education is a crucial social determinant of health. Food insecurity can be detrimental to children's academic achievement, potentially perpetuating a cycle of poverty and food insecurity. We aimed to assess the relationship between food insecurity and academic achievement in Canadian school-aged children. DESIGN: Cross-sectional study of children and parents. Parents completed the short-form Household Food Security Survey Module and questions about income and education level (socio-economic status). Children completed FFQ. Data were prospectively linked to children's performance on standardized exams written one year later. Mixed-effect logistic regression was employed to assess the relationship between food insecurity and likelihood of meeting academic expectations adjusting for socio-economic status, diet quality and potential confounders. SETTING: Nova Scotia, Canada in 2011-2012. SUBJECTS: Students (n 4105) in grade 5 (10-11 years; 2167 girls) and their parents. RESULTS: Low food security was reported by 9·8 % of households; very low food security by 7·1 % of households. Students from low-income households and reporting poor diet quality were less likely to do well in school. Children who lived in households reporting very low food security had 0·65 times the odds (OR=0·65; 95 % CI 0·44, 0·96) of meeting expectations for reading and 0·62 times the odds (OR=0·62; 95 % CI 0·45, 0·86) of meeting expectations for mathematics. CONCLUSIONS: Very low household insecurity is associated with poor academic achievement among children in Nova Scotia.

OBJECTIVE: Food security (FS) exists when all people, at all times, have physical and economic access to sufficient, safe and nutritious food to meet their needs. The present research sought to determine whether students from households experiencing moderate or severe food insecurity (FI) had poorer diet quality, higher body weights and poorer psychosocial outcomes than students from households classed as having high FS or marginal FI status. DESIGN: Population-based survey conducted in schools. Multiple regression analysis was used to explore associations between FS status (high FS; marginal, moderate, severe FI), dietary behaviours and intake, and health-related outcomes (body weight, quality of life, mood, peer relationships, externalizing problems). SETTING: Nova Scotia, Canada. SUBJECTS: Grade 5 students (n 5853), aged 10-11 years, with complete information on FS status and student outcomes. RESULTS: In this sample, rates of household FS were 73·5% (high FS), 8·3% (marginal FI) 10·2% (moderate FI) and 7·1% (severe FI status). Students living in households experiencing moderate or severe FI had poorer diet quality, higher BMI and poorer psychosocial outcomes than students classed as having high FS or marginal FI. CONCLUSIONS: These findings provide important evidence for policy makers on the prevalence of FI among families in Nova Scotia with grade 5 children and its relationship with childhood nutrition, psychosocial and quality of life factors, and weight status.
