Upper GI bleeding in healthy full-term infants: a case-control study

Abstract OBJECTIVE To investigate the cause of intracranial hemorrhage among full-term infants. METHODS A retrospective, hospital-based, matched case-control study was conducted at London Health Sciences Center, in southwestern Ontario, for the period from January 1, 1985, to December 31, 1996. Cases were diagnosed with magnetic resonance imaging, computed tomography, or ultrasonography within 7 days after birth. Control subjects were matched with respect to year of birth, sex, and, for nontransferred case patients only, obstetrician. RESULTS Sixty-six full-term infants with intracranial hemorrhage were identified, and 104 control subjects were matched. Each factor was independently associated with increased risk of intracranial hemorrhage, as follows: forceps assistance (odds ratio [OR], 4.3; 95% confidence interval [CI], 1.2–15.1), compared with spontaneous vaginal delivery; 1-minute Apgar scores of 1 through 4 (OR, 110; 95% CI, 5.0–2400) and 5 through 8 (OR, 4.9; 95% CI, 1.3–18.3), compared with scores of 9 or 10 (corresponding 5-min Apgar scores were also statistically significant); and requirements for resuscitation (OR, 5.1; 95% CI, 1.8–14.1), compared with no resuscitation requirements. Of the 52 case patients for whom platelet counts were recorded within 48 hours after birth, 30.8% (95% CI, 18.3–43.3%) exhibited counts of less than 70 × 109/L. Platelet counts of less than 50 × 109/L were specifically associated with intraparenchymal hemorrhage and a more severe radiological grade. Forceps-associated hemorrhage was more frequently subarachnoid and subdural and less frequently intraparenchymal. Such hemorrhage also tended to be more caudal in location. CONCLUSION Thrombocytopenia seems to be an important cause of intraparenchymal hemorrhage, and the use of forceps is more likely to be associated with subarachnoid and subdural hemorrhage.

Objective Low birth weight (LBW) infants (<2,500 g) continued to be a global health problem because of the associated short- and long-term adverse outcomes. The study aimed to determine the prevalence, risk factors, and short-term outcomes of term LBW infants Study Design A prospective and case–control study. All infants born consecutively from September 1, 2018 to August 31, 2019 were included. Cases, term LBW infants, were 1:1 matched to controls, appropriate for gestational age (AGA) term infants. Major congenital or chromosomal anomalies and multiple pregnancies were excluded. Results The prevalence of term LBW in the studied period was 4.8%. Mothers of term LBW infants had significantly lower body mass index (p = 0.05), gained less weight (p = 0.01), had a history of previous LBW (p = 0.01), and lower monthly income (p = 0.04) compared with mothers of term AGA infants even after adjustment for confounders. A nonsignificant higher number of term LBW infants needed NICU admission, while their need for phototherapy was deemed significant. Conclusion We identified nutritional and socioeconomic maternal factors that are significantly associated with LBW infants and should be targeted during antenatal visits to improve neonatal outcomes.

Abstract Objectives i) To compare the placental human papilloma virus (HPV) deoxynucleic acid (DNA) status of preterm deliveries with full term deliveries and to identify high risk (HR) genotypes (HPV 16 and 18); and ii) To compare the perinatal outcomes of HPV positive with HPV negative pregnant women. Methods A case control study was carried out on 100 antenatal women with singleton live pregnancies admitted in labor ward of a tertiary care teaching hospital from April 2017 to March 2018. The two study groups were i) spontaneous preterm deliveries between 24 and 36 + 6 weeks (n=50) and ii) full term deliveries ≥37 weeks (n=50). The placental tissue was analysed for HPV DNA and HR HPV genotypes were detected by type specific primers. A comparative analysis of perinatal outcomes between HPV positive and negative women was done. Results An overall placental tissue HPV prevalence of 12% (12/100) was observed in study cohort which was not significantly different between preterm and full term deliveries (16 vs. 8%, p=0.218). HPV 16 was significantly associated with preterm births (p=0.04). Both HPV affected and non-affected women were comparable in terms of mode of delivery and neonatal outcomes. However, a statistically significant association of preterm neonatal intensive care admissions with HR HPV 16 genotype was observed (p=0.04). Conclusions Spontaneous preterm births can be attributed to placental HPV infection, specifically HR HPV 16 genotype. This association identifies a potentially preventable cause of prematurity and its associated complications, in wake of availability of an effective vaccine.
