Background: Survivors of breast and prostate cancer, especially those that are Black and/or Hispanic, are at high risk for cardiovascular events. Physical activity can reduce the risk of cardiovascular events in cancer survivors, but Black and Hispanic people are less likely to engage in routine physical activity. Concepts from behavioral economics have been used to design scalable, low-touch gamification interventions that increase physical activity in individuals at high risk for cardiovascular events, but the effectiveness of these strategies in Black and Hispanic survivors of breast and prostate cancer is uncertain.

Advancing Interpretable Regression Analysis for Binary Data: A Novel Distributed Algorithm Approach.

Stat Med

December 2024

Center for Health AI and Synthesis of Evidence (CHASE), Department of Biostatistics, Epidemiology and Informatics, Perelman School of Medicine, University of Pennsylvania, Philadelphia, Pennsylvania, USA.

Article Synopsis
  • Sparse data bias is an issue in data analysis, especially for rare binary outcomes, and while a two-step meta-analysis can help, it doesn't fully eliminate bias in effect estimation.
  • The authors propose a new algorithm called ODAP-B, which utilizes modified Poisson regression to estimate relative risk more accurately and efficiently than traditional methods.
  • Evaluations through simulations and real-world data reveal that ODAP-B provides closer effect estimates and is more privacy-preserving since it only requires aggregated data.

Behavioral economics research suggests poverty may influence behavior by reducing mental bandwidth, increasing future discounting, and increasing risk aversion. It is plausible these decision-making processes are further impaired in the context of HIV or pregnancy. In this cross-sectional study of 86 low-income women in Philadelphia, HIV was associated with lower mental bandwidth (one of two measures) and lower risk aversion.

Article Synopsis
  • Delaying elective noncardiac surgery after an acute myocardial infarction (NSTEMI) leads to better health outcomes, but existing guidelines are outdated and based on old data.
  • A study analyzed Medicare data from surgeries between 2015 and 2020, focusing on patients 67 and older, to determine how the time since an NSTEMI affects postoperative risks.
  • Results showed that surgeries performed within 30 days of an NSTEMI significantly increased the chances of major cardiovascular and cerebrovascular events, with risks leveling off after 30 days for those who had heart procedures, but increasing again after 180 days.

Risk for Financial Precarity From Hospitalization: Implications for Targeting Financial Assistance in Medicare.

Ann Intern Med

December 2024

Department of Medicine, University of Pennsylvania Perelman School of Medicine, and Leonard Davis Institute of Health Economics, University of Pennsylvania, Philadelphia, Pennsylvania (P.C., E.T.R.).

Background: High out-of-pocket costs in Medicare may leave many beneficiaries in financial precarity. Beneficiaries with modest incomes are often ineligible for Medicaid (which covers most out-of-pocket Medicare costs) and may have insufficient resources to pay an unexpected health care bill. This has prompted calls to improve financial protections, but the target population remains uncharacterized.

Risk of Opioid Overdose Associated with Concomitant Use of Methadone and Statins.

Clin Pharmacol Ther

February 2025

Center for Real-World Effectiveness and Safety of Therapeutics, Perelman School of Medicine, University of Pennsylvania, Philadelphia, Pennsylvania, USA.

Article Synopsis
  • * A study using Medicaid claims from 2003 to 2020 assessed the overdose rates among users of methadone and different statins, specifically comparing P-gp-inhibiting statins (simvastatin, atorvastatin, lovastatin) with rosuvastatin as a control.
  • * Results showed no significant association between the use of P-gp-inhibiting statins and opioid overdose risk, indicating that using these statins alongside methadone may not increase the risk compared to using rosuvastatin.
