Iron or Multiple Micronutrient Powder Supplements With Malaria Chemoprevention in Rural Malawian Children: The IRMA Randomized Clinical Trial

Aug 6, 2026

The study aimed to determine whether universal iron interventions combined with malaria chemoprevention would enhance cognitive outcomes and safety regarding infection risk in rural Malawian children. The results indicated that neither iron syrup nor iron-containing micronutrient powders improved cognitive scores compared to malaria chemoprevention alone, and both iron interventions did not increase malaria risk. Overall, the findings suggest that these iron interventions did not provide the expected functional benefits in this population.

Duration of Therapeutic Hypothermia After Out-of-Hospital Cardiac Arrest: The ICECAP Randomized Clinical Trial

Aug 5, 2026

The ICECAP randomized clinical trial aimed to determine the optimal duration of therapeutic hypothermia at 33 °C for maximizing neurological recovery in comatose survivors of out-of-hospital cardiac arrest. The study found that increasing the duration of cooling did not improve neurological outcomes, with a posterior probability suggesting that a 6-hour duration may be optimal. Overall, no significant differences in secondary outcomes or mortality were observed across varying cooling durations.

Classic Hodgkin Lymphoma: A Review

Aug 3, 2026

This review aims to provide a comprehensive overview of classic Hodgkin lymphoma (cHL), including its epidemiology, clinical presentation, risk factors, and treatment strategies. The authors highlight that cHL primarily affects younger individuals and that first-line treatment typically involves chemotherapy, with potential additions of radiotherapy and novel agents for certain patient groups. They also discuss the long-term risks faced by survivors, emphasizing the importance of monitoring for secondary malignancies and other complications.

Addition of High-Dose Vitamin D3 to Standard Treatment in Patients With Metastatic Colorectal Cancer: The SOLARIS Randomized Clinical Trial (Alliance A021703)

Aug 3, 2026

The SOLARIS trial aimed to determine whether high-dose vitamin D3, when added to standard chemotherapy, improves outcomes in patients with previously untreated metastatic colorectal cancer (mCRC). The study found that high-dose vitamin D3 did not significantly enhance progression-free survival compared to standard-dose vitamin D3, nor did it show improvements in overall survival or response rates. Overall, the addition of high-dose vitamin D3 did not provide clinically meaningful benefits in this patient population.

Initial HIV Therapy for Adults and Treatment-Associated Weight Gain: The Opti-DOR Randomized Clinical Trial

Jul 31, 2026

The study aimed to determine whether a regimen of doravirine, lamivudine, and tenofovir disoproxil fumarate results in less weight gain compared to a regimen of dolutegravir, emtricitabine, and tenofovir alafenamide while maintaining similar levels of viral suppression in ART-naive adults with HIV. The findings indicated that both regimens achieved comparable viral suppression rates at 48 weeks, but the doravirine-based regimen was associated with significantly less weight gain. This suggests that the doravirine regimen may be a preferable option for managing weight-related concerns in individuals starting HIV treatment.

Dapagliflozin and Acute Kidney Injury Following Cardiac Surgery: A Randomized Clinical Trial

Jul 30, 2026

This randomized clinical trial aimed to determine whether initiating dapagliflozin one day prior to elective cardiac surgery could reduce the incidence of acute kidney injury (AKI) within the first week post-surgery. The results showed that dapagliflozin significantly decreased AKI rates compared to placebo (28% vs. 52%), suggesting its potential as a preventive treatment in this patient population. Adverse events such as atrial fibrillation and reoperation rates were similar between the two groups.

Nicotine E-Cigarettes for Cigarette Smoking Cessation: Recommendations to US-Based Clinicians

Jul 30, 2026

The authors aim to address how clinicians can effectively integrate e-cigarettes into smoking cessation discussions with patients, given their potential benefits compared to traditional nicotine replacement therapies. They provide evidence-based recommendations for engaging patients in shared decision-making about the risks and benefits of e-cigarettes, while also clarifying common misconceptions about their safety. Ultimately, the paper advocates for the inclusion of e-cigarettes as a viable option in pharmacologic treatments for smoking cessation to mitigate the health risks associated with cigarette smoking.

Global Burden of Elevated LDL-C: Findings From the Global Burden of Disease Study 2023

Jul 29, 2026

The authors aimed to estimate the global, regional, and national burden of ischemic heart disease and ischemic stroke attributable to elevated low-density lipoprotein cholesterol (LDL-C) from 1990 to 2023, assessing the impact of population growth, aging, and exposure changes. They found that elevated LDL-C accounted for 3.6 million deaths and 90.7 million disability-adjusted life years (DALYs) in 2023, with significant regional disparities and a notable shift of the burden towards middle-sociodemographic countries. Despite a decline in age-standardized rates, the absolute burden of LDL-C has increased due to demographic changes, highlighting the need for improved prevention and treatment strategies.

Multidomain Intervention for Growth in Term Small-for-Gestational-Age Infants: A Randomized Clinical Trial

Jul 27, 2026

This study aimed to evaluate the effectiveness of a multidomain intervention package on the growth and neurodevelopment of term small-for-gestational-age (SGA) infants compared to usual care. The results indicated that the intervention significantly improved weight, weight-for-age z scores, and cognitive outcomes, while also reducing the prevalence of underweight, stunting, wasting, and anemia among the infants. Overall, the integrated intervention demonstrated beneficial effects on both physical growth and neurodevelopmental outcomes in this vulnerable population.

Safe Sleep Video Intervention via Text Messaging to Low-Income Families: The SMARTER Randomized Clinical Trial

Jul 23, 2026

The study aimed to evaluate the effectiveness of a text-delivered video intervention promoting safe sleep practices among low-income families participating in the WIC program. Although the intervention did not significantly impact the primary outcomes related to safe sleep practices, it did show a higher rate of exclusive supine positioning at 60 days among participants who received the prenatal intervention compared to controls. Overall, the findings suggest limited effectiveness of the intervention in improving adherence to safe sleep practices.
