Maternal Smoking and Congenital Heart Defects, National Birth Defects Prevention Study, 1997-2011

J Pediatr. 2021 Sep 8:S0022-3476(21)00877-5. doi: 10.1016/j.jpeds.2021.09.005. Online ahead of print. ABSTRACT OBJECTIVES: To assess associations between maternal smoking and congenital heart defects (CHDs) in offspring. STUDY DESIGN: We performed a retrospective case-control study using data for cases of CHD (n=8,339) and non-malformed controls (n=11,020) children from all years (1997-2011) of the National Birth Defects […]

Perspectives of Pediatric Providers Regarding Clinical Use of Pharmacogenetics

S D Med. 2021 Jul;74(7):294-301. ABSTRACT INTRODUCTION: A major goal of the current personalized medicine era is to utilize pharmacogenetics (PGx) in order to influence how medications and therapies are prescribed by providers. However, disparities for prescribing medications between adults and children exist. Research has shown that children are not just small adults and there […]

Integrative genetic, genomic and transcriptomic analysis of heat shock protein and nuclear hormone receptor gene associations with spontaneous preterm birth

Sci Rep. 2021 Aug 24;11(1):17115. doi: 10.1038/s41598-021-96374-9. ABSTRACT Heat shock proteins are involved in the response to stress including activation of the immune response. Elevated circulating heat shock proteins are associated with spontaneous preterm birth (SPTB). Intracellular heat shock proteins act as multifunctional molecular chaperones that regulate activity of nuclear hormone receptors. Since SPTB has […]

Detecting methylation quantitative trait loci using a methylation random field method

Brief Bioinform. 2021 Aug 19:bbab323. doi: 10.1093/bib/bbab323. Online ahead of print. ABSTRACT DNA methylation may be regulated by genetic variants within a genomic region, referred to as methylation quantitative trait loci (mQTLs). The changes of methylation levels can further lead to alterations of gene expression, and influence the risk of various complex human diseases. Detecting […]

To Be or No B2: A Rare Cause of Stridor and Weakness in a Toddler

Child Neurol Open. 2021 Aug 5;8:2329048X211030723. doi: 10.1177/2329048X211030723. eCollection 2021 Jan-Dec. ABSTRACT We present a case of a young child with a rare metabolic disorder whose clinical presentation resembled that of autoimmune myasthenia gravis. The differential diagnosis was expanded when autoantibody testing was negative and the patient did not respond to standard immunomodulatory therapies. Rapid […]

Developmental and temporal characteristics of clonal sperm mosaicism

Cell. 2021 Aug 7:S0092-8674(21)00883-7. doi: 10.1016/j.cell.2021.07.024. Online ahead of print. ABSTRACT Throughout development and aging, human cells accumulate mutations resulting in genomic mosaicism and genetic diversity at the cellular level. Mosaic mutations present in the gonads can affect both the individual and the offspring and subsequent generations. Here, we explore patterns and temporal stability of […]

Emergence of an early SARS-CoV-2 epidemic in the United States

Emergence of an early SARS-CoV-2 epidemic in the United States, Cell (2021), The emergence of the COVID-19 epidemic in the United States (U.S.) went largely undetected due to inadequate testing. New Orleans experienced one of the earliest and fastest accelerating outbreaks, coinciding with Mardi Gras. To gain insight into the emergence of SARS-CoV-2 in the […]
