Purpose: Radiation Therapy Oncology Group (RTOG) recursive partitioning analysis (RPA) prognostic classes I and II for patients with brain metastases is derived from a database made up primarily of patients with unresected and multiple metastases. An analysis of a previously published randomized trial was performed to determine the applicability of these RPA prognostic classes in the setting of resection of single metastases to the brain.
Patients And Methods: Ninety-five patients with single metastases to the brain that were treated with complete surgical resection entered this study. Patients were randomly assigned to treatment with postoperative whole brain radiotherapy (WBRT) (n = 49 patients) or no further brain treatment (n = 46 patients). All patients entered on this study had a Karnofsky performance status of > or =70. Therefore, although the RTOG RPA has 3 classes, only patients with RPA classes I (n = 26) or II (n = 69) were eligible for this study analysis.
Results: For RPA class I, the median survival was 10.9 months versus 9.8 months for class II patients (P = 0.45). Multivariate analysis showed that only postoperative WBRT, independent of RPA class I or II, lessened the risk of brain tumor recurrence (P < 0.0001).
Conclusion: This analysis of a randomized trial evaluating postoperative WBRT in the treatment of single metastases to the brain showed no difference in survival between RPA class I or II patients. In addition, the use of postoperative WBRT after complete surgical resection of single brain metastases results in substantially better control of disease in the brain independent of RPA classes I or II.

JAMA Cardiol
January 2025
Center for Health Incentives and Behavioral Economics, University of Pennsylvania, Philadelphia.
Importance: A comprehensive lipid panel is recommended by guidelines to evaluate atherosclerotic cardiovascular disease risk, but uptake is low.
Objective: To evaluate whether direct outreach including bulk orders with and without text messaging increases lipid screening rates.

Palliative Care Program for Community-Dwelling Individuals With Dementia and Caregivers: The IN-PEACE Randomized Clinical Trial.
JAMA
January 2025
Division of General Internal Medicine and Geriatrics, Indiana University School of Medicine, Indianapolis.
Importance: Care management benefits community-dwelling patients with dementia, but studies include few patients with moderate to severe dementia or from racial and ethnic minority populations, lack palliative care, and seldom reduce health care utilization.
Objective: To determine whether integrated dementia palliative care reduces dementia symptoms, caregiver depression and distress, and emergency department (ED) visits and hospitalizations compared with usual care in moderate to severe dementia.
Design, Setting, And Participants: A randomized clinical trial of community-dwelling patients with moderate to severe dementia and their caregivers enrolled from March 2019 to December 2020 from 2 sites in central Indiana (2-year follow-up completed on January 7, 2023).

Importance: Hypertension is the primary cardiovascular risk factor in Africa. Recently revised World Health Organization guidelines recommend starting antihypertensive dual therapy; clinical efficacy and tolerability of low-dose triple combination remain unclear.
Objectives: To compare the effect of 3 treatment strategies on blood pressure control among persons with untreated hypertension in Africa.

Department of Pediatrics, The Children's Hospital at Montefiore, Albert Einstein College of Medicine, Bronx, New York.
Importance: Pediatric obesity and hypertension are highly correlated. To mitigate both conditions, provision of counseling on nutrition, lifestyle, and weight to children with high blood pressure (BP) measurements is recommended.
Objective: To examine racial and ethnic disparities in receipt of nutrition, lifestyle, and weight counseling among patients with high BP at pediatric primary care visits stratified by patients' weight status.
Imiquimod Cream Preceded by Superficial Curettage vs Surgical Excision for Nodular Basal Cell Carcinoma: A Secondary Analysis of a Randomized Clinical Trial.
JAMA Dermatol
January 2025
Department of Dermatology, Maastricht University Medical Centre, Maastricht, the Netherlands.
Background: Interest in noninvasive treatment of basal cell carcinoma (BCC) has been increasing. For superficial BCC, it has been demonstrated that imiquimod cream, 5%, has high long-term efficacy, but for nodular BCC (nBCC), long-term evidence is sparse.
Objectives: To evaluate whether superficial curettage (SC) followed by imiquimod cream, 5%, is noninferior to surgical excision (SE) in nBCC after 5 years of treatment.
