Introduction: The use of standard-dose cancer treatment can result in a decline in the functional abilities of older adults with cancer. The "start-low, go-slow" (SLGS) strategy involves initiating cancer treatment at lower-than-standard doses in selected patients who are vulnerable to excess toxicity and escalating based on tolerance. We performed a systematic review and meta-analysis to assess the available data and the effectiveness of the SLGS strategy in the treatment of cancer in older adults with incurable solid cancer.

In the United Sates, over 115,000 individuals are diagnosed with a gynecologic cancer annually with access to a gynecologic oncologist and evidence-based treatment remaining a persistent challenge. Coverage decisions by private and public insurance, including Medicaid and Medicare, play key roles in access to care, impacting oncologic outcomes. The expansion of Medicaid insurance under the Affordable Care Act improved early diagnosis, treatment, and survival in gynecologic cancers, but disparities remain for individuals in non-Medicaid expansion states.

Background: People diagnosed with a co-occurring serious mental illness (SMI; ie, major depressive disorder, bipolar disorder, or schizophrenia) but hospitalized for a nonpsychiatric condition experience higher rates of readmissions and other adverse outcomes, in part due to poorly coordinated care transitions. Current hospital-to-home transitional care programs lack a focus on the integrated social, medical, and mental health needs of these patients. The Thrive clinical pathway provides transitional care support for patients insured by Medicaid with multiple chronic conditions by focusing on posthospitalization medical concerns and the social determinants of health.

Cost of care associated with utilization of telehealth in clinical trials.

Gynecol Oncol Rep

December 2024

Department of Obstetrics and Gynecology, Division of Gynecologic Oncology, University of Pennsylvania School of Medicine, Philadelphia, PA, USA.

Objective: Due to COVID-19 pandemic restrictions, telehealth was incorporated into standard oncologic care and clinical trial operations. We sought to analyze whether telehealth changed cost of care compared to traditional clinical trial operations.

Methods: We conducted a retrospective cohort study of gynecologic oncology patients enrolled in therapeutic clinical trials at a National Cancer Institute designated center, comparing the cost of cancer care on trial pre-TELEhealth (9/30/2019 to 3/15/2020) versus during TELEhealth (3/16/2020 to 8/20/2020).

This study argues that value assessment conducted from a societal perspective should rely on the Generalized Cost-Effectiveness Analysis (GCEA) framework proposed herein. Recently developed value assessment inventories - such as the Second Panel on Cost-Effectiveness's "impact inventory" and International Society of Pharmacoeconomics Outcomes Research (ISPOR) "value flower" - aimed to more comprehensively capture the benefits and costs of new health technologies from a societal perspective. Nevertheless, application of broader value elements in practice has been limited in part because quantifying these elements can be complex, but also because there have been numerous methodological advances since these value inventories have been released (e.

Nearly 1 in 5 families with children in the United States are food insecure. Hospitalization of a child can exacerbate food insecurity, both during the hospitalization and after discharge. Although some hospitals provide free or subsidized meals during hospitalization, few address food insecurity in the immediate posthospitalization period.

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

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.
