Coronary Artery Calcium Score and Polygenic Risk Score for the Prediction of Coronary Heart Disease Events
SS Khan et al, JAMA Network Open, May 23, 2023

Does discrimination change when either a coronary artery calcium score or a polygenic risk score is added to a coronary heart disease (CHD) prediction model based on traditional risk factors? In 2 population-based studies involving 3208 adults aged 45 years through 79 years (Multi-Ethnic Study of Atherosclerosis [MESA], median age 61 years and the Rotterdam Study [RS], median age, 67 years) and of European ancestry, a coronary artery calcium score significantly improved discrimination when added to a traditional risk factor–based score (MESA, 0.09; Rotterdam Study, 0.06), but the polygenic risk score did not. Similar findings were observed when stratified by median age.

Link Between Long Telomeres and Long Life Is a Tall Tale, Study Finds
G Kolata, NY Times, May 4, 2023

The longer a person’s telomeres, researchers found, the greater the risk of cancer and other disorders, challenging a popular hypothesis about the chromosomal roots of vitality. While short telomeres do lead to health problems, long telomeres lead to health problems of their own. Far from extending life, long telomeres appear to cause cancer and a blood disorder known as CHIP, a condition that increases the risk of blood cancers and heart disease.

Cardiovascular Disease Risk Assessment Using Traditional Risk Factors and Polygenic Risk Scores in the Million Veteran Program.
Jason L Vassy et al. JAMA Cardiol 2023 5

Do polygenic risk scores (PRSs) for coronary heart disease and acute ischemic stroke predict incident atherosclerotic cardiovascular disease (ASCVD) events? In an ancestrally diverse, primary prevention sample of almost 80?000 veterans observed for up to 7 years, PRSs were significantly associated with incident myocardial infarction, acute ischemic stroke, and cardiovascular death. Discrimination was modest overall but greater among women and younger participants.

Implementation of Newborn Screening for Conditions in the United States First Recommended during 2010–2018
S Singh et al, IJNS, April 2023

During 2010–2022, seven conditions were added to the RUSP: severe combined immunodeficiency (SCID) (2010), critical congenital heart disease (CCHD) (2011), glycogen storage disease, type II (Pompe) (2015), mucopolysaccharidosis, type I (MPS I) (2016), X-linked adrenoleukodystrophy (X-ALD) (2016), spinal muscular atrophy (SMA) (2018), and mucopolysaccharidosis, type II (MPS II) (2022). The adoption of SCID and CCHD newborn screening by programs in all 50 states and three territories (Washington, D.C.; Guam; and Puerto Rico) took 8.6 and 6.8 years, respectively.
