Continuous Glucose Monitoring in Type 2 Diabetes and Beyond: A Review

Aug 3, 2026

The authors aim to evaluate the efficacy and appropriateness of continuous glucose monitoring (CGM) for individuals with type 2 diabetes and beyond, given its initial focus on type 1 diabetes. They found that while CGM can lead to a modest reduction in hemoglobin A1c for some patients with type 2 diabetes, evidence for its use in those not on glucose-lowering therapy or in populations like prediabetics remains limited. The authors advocate for a targeted approach to CGM deployment, ensuring it aligns with patient needs and clinical contexts to maximize benefits and prevent overuse.

Autonomous Oxygen Titration for Maintaining Normoxemia in Acutely Ill Adults: The SAVE-O2 AI Randomized Clinical Trial

Aug 3, 2026

The authors aimed to determine whether autonomous oxygen titration could increase the time acutely ill adults spent in the targeted normoxemia range compared to usual care. The study found that patients receiving autonomous oxygen titration spent significantly more time in the normoxemia range (85% vs. 63%) and less time in hypoxemia (2.0% vs. 3.6%) than those under manual titration by clinicians. These results suggest that autonomous titration may improve oxygen management in hospitalized patients.

High-Efficiency Particulate Air Filters to Prevent Winter Respiratory Infections in Care Homes: The AFRI-c Cluster Randomized Clinical Trial

Jul 27, 2026

The study aimed to determine whether the use of portable high-efficiency particulate air (HEPA) filters in care homes reduces the incidence of respiratory infections among residents. The trial found no significant difference in respiratory infection rates or staff absenteeism between care homes using HEPA filters and those without. The authors concluded that existing infection prevention measures should continue, as HEPA filters did not demonstrate additional benefits in this context.

An Indigenous Food Is Medicine Intervention: The MUTTON-HF Randomized Clinical Trial

Jul 27, 2026

The authors aimed to evaluate the efficacy of a culturally and medically tailored meal program, incorporating traditional Navajo foods, on reducing hospitalizations and emergency department visits among adults with heart failure. The randomized clinical trial found that participants in the intervention group experienced significantly fewer hospitalizations and improved quality of life measures compared to those receiving usual dietary advice. These findings suggest that community-based interventions utilizing traditional foods can enhance health outcomes in Indigenous populations.

Initiation, Adherence, and Persistence to Guideline-Directed Medical Therapy After Heart Failure Hospitalization

Jul 20, 2026

The authors aimed to characterize medication-use patterns following heart failure (HF) hospitalizations, specifically focusing on the initiation, adherence, and persistence of guideline-directed medical therapy. They found that a significant proportion of new prescriptions were not filled, with only 54% initiated within 7 days post-discharge, and at 6 months, only 42% of patients were adherent and 51% persistent to their medications. These findings highlight the need for interventions to improve medication use after hospital discharge for HF patients.

Moral Injury Among Physicians Caring for Immigrant Patients Amid Anti-Immigrant Policies

Jul 20, 2026

This study investigates the impact of anti-immigrant policies enacted in January 2025 on primary care physicians' well-being and their immigrant patients' health. Through qualitative interviews, the authors identify themes related to moral injury experienced by physicians, including conflicts between ethical values and professional responsibilities, the vulnerability of immigrant patients, and varying responses from healthcare systems. Despite these challenges, the study highlights how physicians have adapted their practices to support both patients and themselves, mitigating some effects of moral injury.

Low-Value Services and Longitudinal Knowledge Assessment Performance

Jul 13, 2026

The authors aimed to investigate the relationship between the use of low-value services (LVSs) in healthcare and physicians' clinical knowledge, as measured by their performance on the Longitudinal Knowledge Assessment (LKA). The study found that patients treated by physicians with higher LKA scores were significantly less likely to receive LVSs, indicating that better clinical knowledge may be associated with more judicious use of healthcare resources.

Quality, Cost, and Timeliness of Cancer Treatment in Medicare Advantage and Traditional Medicare

Jul 13, 2026

This study investigates whether the type of Medicare insurance—Medicare Advantage (MA) or Traditional Medicare (TM)—affects the quality and cost of cancer treatment. The authors found that while MA beneficiaries had similar rates of receiving optimal cancer treatment compared to TM beneficiaries, they experienced significantly lower treatment costs. Overall, the findings suggest that MA may provide cost-effective cancer care without compromising treatment quality.

Respiratory Outbreak Mitigation With Point-of-Care Testing in Long-Term Care: A Randomized Clinical Trial

Jul 6, 2026

This study aimed to evaluate the impact of on-site point-of-care respiratory multiplex polymerase chain reaction (POC-RMPCR) testing on respiratory infection outbreaks in nursing homes (NHs). The findings indicated that while the use of POC-RMPCR did not significantly alter the number or size of outbreaks, it led to a reduction in emergency department transfers and improved viral testing and treatment initiation for residents. The authors suggest that seasonal implementation of POC-RMPCR could enhance patient management in NHs.

Prenatal Acetaminophen (Paracetamol) Use and the Risk of Autism and/or Attention-Deficit/Hyperactivity Disorder Among Sibling-Matched Cohorts

Jun 29, 2026

The authors aimed to investigate the association between prenatal exposure to paracetamol (acetaminophen) and the risk of autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD) in offspring, utilizing a sibling-matched cohort design to control for familial confounding. Their findings indicated no significant association between prenatal paracetamol use and the development of ASD or ADHD, suggesting that previously observed positive correlations in conventional studies may be due to residual familial factors. This research provides reassurance regarding the safety of paracetamol use during pregnancy.
