What Is Prediabetes?
J Jin, JAMA Patient Corner, December 1, 2023 (Posted Dec 02, 2023 9AM)

From the article: " Prediabetes affects approximately 1 in 3 US adults and about 720 million individuals worldwide. People with prediabetes often have no symptoms, so most people with prediabetes do not know they have it. Risk Factors for Prediabetes include: Being older than 45 years; Being overweight or obese; Being physically active less than 3 times a week; Eating an unhealthy diet; Having a parent or sibling with type 2 diabetes; Having a history of diabetes during pregnancy (gestational diabetes) or giving birth to an infant weighing more than 9 pounds; Having polycystic ovary syndrome."

Cord blood DNA methylation signatures associated with preeclampsia are enriched for cardiovascular pathways: insights from the VDAART trial.
Hanna M Knihtilä et al. EBioMedicine 2023 11 104890 (Posted Nov 29, 2023 9AM)

From the abstract: "Preeclampsia has been associated with maternal epigenetic changes, in particular DNA methylation changes in the placenta. It has been suggested that preeclampsia could also cause DNA methylation changes in the neonate. We examined DNA methylation in relation to gene expression in the cord blood of offspring born to mothers with preeclampsia. This study included 128 mother-child pairs who participated in the Vitamin D Antenatal Asthma Reduction Trial (VDAART), where assessment of preeclampsia served as secondary outcome. We found that preeclampsia is related to differential cord blood DNA methylation signatures of cardiovascular pathways, including the apelin signaling pathway. "

Down Syndrome in a New Era for Alzheimer Disease.
Michael S Rafii et al. JAMA 2023 11 (Posted Nov 29, 2023 9AM)

From the paper: "Despite the ultra-high risk for Alzheimer disease and its effect of a shortened life expectancy, persons with Down syndrome who are experiencing Alzheimer disease–related cognitive decline have limited access to expert clinical evaluation for dementia, let alone these newly approved therapeutics. At the same time, because of the genetic basis for lifelong amyloid accumulation, there are also significant concerns related to cerebral amyloid angiopathy and the risk of adverse events related to amyloid-related imaging abnormalities (ARIA). This requires careful assessment of safety and tolerability in individuals with Down syndrome to be done before these drugs can be widely prescribed in this vulnerable population. "

Prevalence of chromosomal alterations in first-trimester spontaneous pregnancy loss.
Rick Essers et al. Nat Med 2023 11 (Posted Nov 27, 2023 10AM)

From the abstract: "Pregnancy loss is often caused by chromosomal abnormalities of the conceptus. The prevalence of these abnormalities and the allocation of (ab)normal cells in embryonic and placental lineages during intrauterine development remain elusive. In this study, we analyzed 1,745 spontaneous pregnancy losses and found that roughly half (50.4%) of the products of conception (POCs) were karyotypically abnormal, with maternal and paternal age independently contributing to the increased genomic aberration rate.
