Clinical and Genetic Risk Factors for Acute Incident Venous Thromboembolism in Ambulatory Patients With COVID-19
J Xie et al, JAMA Internal Medicine, August 18, 2022

What is the 30-day acute risk of venous thromboembolism (VTE) among ambulatory patients with COVID-19, and what are the clinical and genetic risk factors predisposing them to developing post–COVID-19 VTE? In this retrospective cohort study of 18?818 outpatients with COVID-19 and 93?179 propensity score–matched noninfected participants, a higher VTE incidence was observed in the former (hazard ratio, 21.42); however, this risk was considerably attenuated among the fully vaccinated, after breakthrough infection. Older age, male sex, obesity, no vaccination or partial vaccination, and inherited thrombophilia were independent risk factors for COVID-19–associated VTE.

Predicting chronic morbidity in childhood cancer survivors.
Vrooman Lynda M et al. Nature medicine 2022 8

Approximately 85% of children diagnosed with cancer will be cured of their primary cancer, but epidemiologic and clinical studies have characterized a significant burden of morbidity, as well as excess early mortality, in survivors. Two recent studies show that incorporating genetic factors into risk models improves the prediction of severe obesity for survivors of childhood cancer, which could promote early interventions and better long-term care.

Genetic risk score enhances the risk prediction of severe obesity in adult survivors of childhood cancer.
Sapkota Yadav et al. Nature medicine 2022 7

We show the contribution of genetic risk scores (GRSs) to increase prediction of those survivors of childhood cancer who are at risk for severe obesity (body mass index =40?kg?m-2) as an adult. Among 2,548 individuals of European ancestry from the St. Jude Lifetime Cohort Study who were 5-year survivors of childhood cancer, the GRS was found to be associated with 53-fold-higher odds of severe obesity. Addition of GRSs to risk prediction models based on cancer treatment exposures and lifestyle factors significantly improved model prediction (area under the curve increased from 0.68 to 0.75, resulting in the identification of 4.3-times more high-risk survivors).

Risk Factors for COVID-19 Mortality in Pediatric Populations: A Scoping Review
J Theophillia et al, Research Square, June 10, 2022

Searches generated a total of 5787 papers and, 78 papers were eligible for analysis. There was a pooled total of 837 pediatric deaths. The presence of at least one comorbidity was a major risk factor; malignancies, cardiovascular diseases and overweight/obesity were the most frequently associated with mortality. The development of Pediatric Multisystem Inflammatory Syndrome (PMIS) was also consistently demonstrated to be a risk factor.
