AI Article Synopsis
- The study focuses on reducing HIV-1 transmission through breastfeeding among infants in Sub-Saharan Africa, where formula feeding can increase child mortality.
- Conducted in Mozambique, the research involved 341 HIV-1 exposed infants and their mothers, providing medical care and counseling for exclusive breastfeeding while administering HAART treatment.
- Results showed a significant reduction in HIV transmission (cumulative rate of 2.8%) and high infant survival rates, suggesting the effectiveness of maternal HAART in decreasing late postnatal HIV transmission.
Article Abstract
Background: Reduction of HIV-1 breast-feeding transmission remains a challenge for prevention of pediatric infections in Sub-Saharan Africa. Provision of formula decreases transmission but often increases child mortality in this setting.
Methods: A prospective observational cohort study of HIV-1 exposed infants of mothers receiving pre and postnatal medical care at Drug Resource Enhancement Against AIDS and Malnutrition centers in Mozambique was conducted. Live-born infants of HIV-1-infected women receiving medical care were enrolled. HIV-1 testing was performed at 1, 6, and 12 months of age using branched DNA. Mothers were counseled to breast-feed exclusively for 6 months and were provided HAART antenatally and postnatally for the first 6 months. Women with CD4 cell counts less than 350/cmm at baseline continued HAART indefinitely.
Results: Of 341 infants followed from birth, 313 mother-infant pairs (92%) completed 6 months and 283 (83%) completed 12 months of follow-up. HIV-1 diagnosis was ascertained in 287 infants (84%) including 4 who died. There were 8 cases of HIV-1 transmission: 4 of 341 (1.2%) at 1 month, 2 of 313 (0.6%) at 6 months, and 2 of 276 (0.7%) at 12 months (cumulative rate: 2.8%). Two mothers (0.6%) and 11 infants (3.2%) died. Maternal and infant mortality rates were 587 of 100,000 and 33 of 1000, while country rates are 1000 of 100,000 and 101 of 1000. HIV risk reduction was 93% and HIV-free survival at 12 months was 94%.
Conclusions: Late postnatal transmission of HIV-1 is significantly decreased by maternal use of HAART with high infant survival rates up to 12 months of age.

Technological Adjuncts to Streamline Patient Recruitment, Informed Consent, and Data Management Processes in Clinical Research: Observational Study.
JMIR Form Res
January 2025
Northwestern Medicine, Chicago, IL, United States.
Background: Patient recruitment and data management are laborious, resource-intensive aspects of clinical research that often dictate whether the successful completion of studies is possible. Technological advances present opportunities for streamlining these processes, thus improving completion rates for clinical research studies.
Objective: This paper aims to demonstrate how technological adjuncts can enhance clinical research processes via automation and digital integration.

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.
Design, Setting, And Participants: Pragmatic randomized clinical trial conducted from June 6, 2023, to September 6, 2023, at 2 primary care practices at an academic health system among patients aged 20 to 75 years with at least 1 primary care visit in the past 3 years who were overdue for lipid screening.
Palliative Care Program for Community-Dwelling Individuals With Dementia and Caregivers: The IN-PEACE Randomized Clinical Trial.
JAMA

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: 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.
