Adverse Perinatal Outcomes Associated with Increasing Maternal Obesity.

OBJECTIVE: The aim of this study was to determine adverse perinatal outcomes related to maternal preconception body mass index (BMI). STUDY DESIGN: This is a retrospective observational cohort study at a single institution of 500 consecutive mothers of normal weight with a preconception BMI of 18.5 to less than 25 and 500 additional obese mothers with a preconception BMI more than or equal to 30. Maternal/newborn metrics were stratified by maternal preconception BMI and trend analysis was performed both by simple univariable and multivariable logistic regression analysis. RESULTS: The study included 858 mother/baby dyads after 142 were excluded. Trend analysis demonstrated higher preconception BMI was significantly associated with progressively higher rates of cesarean section (p < 0.001), preeclampsia p < 0.001), gestational diabetes (p < 0.001), preterm birth (p = 0.001), lower 1- and 5 minutes Apgar scores (p < 0.001), and neonatal intensive care unit admission (p = 0.002). These associations remained significant in both simple univariable and multivariable logistic regression models. CONCLUSION: We demonstrated obese women are more likely to have maternal complications and neonatal morbidity when compared with normal weight mothers. Maternal and fetal complications increase with increasing obesity with superobese mothers (BMI ≥ 50) having more perinatal adverse outcomes when compared with other classes of obesity. It is reasonable to counsel weight loss prior to conception of women with BMI more than or equal to 30 in an effort to reduce maternal complications and neonatal morbidity related to pregnancy. KEY POINTS: · Maternal obesity is associated with adverse outcomes.. · Complications increase with increasing obesity.. · Superobese mothers have the most adverse outcomes..

Persistent Hypoglycemia with Polycystic Kidneys: A Rare Combination - A Case Report.

We present the case of an infant referred to our NICU born at 39 weeks' gestation with persistent hypoglycemia with elevated insulin levels (HI) requiring diazoxide to maintain normoglycemia. Additionally, polycystic kidney disease (PKD) was detected by ultrasound. Molecular genetic testing revealed pathogenic variants in the PMM2gene, i.e., a variant in the promoter region and a missense variant in the coding region. The precoding variant was recently described in 11 European families with similar phenotypes, either in a homozygous state or as compound heterozygous with a pathogenic coding variant. In neonates with HI associated with PKD, this rare recessive disorder should be considered.

Rickets treatment improves more than bone health in toddler with autism spectrum disorder: A brief report.

Children with autism spectrum disorder have been found to have lower levels of vitamin D than their peers. Our case report supports the hypothesis that vitamin D may be an effective treatment for developmental delay in autism. In addition, we review the literature surrounding vitamin D deficiency as a potential cause of autism spectrum disorder and the role that vitamin D may play in treatment.
