Background: Continuous glucose monitoring (CGM) may improve self-management and reduce hypoglycemia risk among individuals with diabetes. However, little is known about how older adults with insulin-treated type 2 diabetes (T2D) experience and incorporate this technology into their daily lives.
Objective: To explore experiences, preferences, barriers, and questions related to using CGM among older adults with insulin-treated T2D with and without experience using CGM.
Design: Qualitative focus group study.
Participants: English-speaking older adults with T2D in a large, integrated healthcare delivery system. Groups included either experienced CGM users or adults who had not previously used CGM. Recruitment efforts prioritized individuals ≥ 75 years of age.
Approach: Transcripts were analyzed using the Framework Method to identify perspectives on CGM. Specific thematic categories were hypoglycemia-related benefits, general benefits, usefulness and ease of use concerns, and CGM questions.
Key Results: The study included 26 participants: 17 (65%) were experienced CGM users, 58% were female; median age was 74 (range 62-88) years. Participants perceived and anticipated these CGM benefits: informing behavior changes, reducing in-the-moment hypoglycemia risk, improving awareness and decision-making, and strengthening clinician collaboration. Perceived CGM barriers included challenges with wearability and reliability, burdens to others, distrust of technology, sensory and learning challenges, insufficient clinician support or engagement, and access and payer hurdles. Despite these downsides, experienced users perceived CGM as a worthwhile alternative to daily fingerstick glucose checks. Non-users were able to formulate many usability questions, providing a snapshot of informational needs for this age group.
Conclusions: Older adults with insulin-treated T2D experienced or anticipated benefits from CGM for diabetes management. Findings indicate a need for tailored education and self-management support for older adults to learn and gain maximal benefit from this technology.

Nicotine Exposure From Smoking Tobacco and Vaping Among Adolescents.
JAMA Netw Open
March 2025
Department of Addictions, Institute of Psychiatry, Psychology and Neuroscience, King's College London, London, United Kingdom.
Importance: It remains unknown whether nicotine intake among youths who vape is lower, comparable, or higher than among youths who smoke.
Objective: To examine potential differences in biomarkers of exposure to nicotine (1) between adolescents who smoke tobacco, vape, both vape and smoke (dual use), or do not use; (2) between adolescents in 3 countries; and (3) by nicotine content and form in the vaping product last used among adolescents who exclusively vaped.
Design, Setting, And Participants: This population-based, observational cross-sectional study invited adolescents aged 16 to 19 years in Canada, England, and the US who had previously completed national surveys to participate in a biomarker study based on their vaping and smoking status.
Association of Diet and Waist-to-Hip Ratio With Brain Connectivity and Memory in Aging.
JAMA Netw Open
March 2025
Department of Psychiatry, University of Oxford, Oxford, United Kingdom.
Importance: Epidemiological studies suggest that lifestyle factors are associated with risk of dementia. However, few studies have examined the association of diet and waist to hip ratio (WHR) with hippocampus connectivity and cognitive health.
Objective: To ascertain how longitudinal changes in diet quality and WHR during midlife are associated with hippocampal connectivity and cognitive function in later life.
Frailty Trajectories Following Adjuvant Chemotherapy and Mortality in Older Women With Breast Cancer.
JAMA Netw Open
March 2025
Department of Epidemiology, Gillings School of Global Public Health, University of North Carolina at Chapel Hill, Chapel Hill.
Importance: Frailty assessed at a single time point is associated with mortality in older women with breast cancer. Little is known about how changes in frailty following cancer treatment initiation affect mortality.
Objective: To evaluate the association between claims-based frailty trajectories following adjuvant chemotherapy initiation and 5-year mortality in older women with stage I to III breast cancer.
Increased mortality and morbidity risk in people with early HIV care interruption in Spain, 2004-2023.
AIDS
March 2025
National Center for Epidemiology, Carlos III Health Institute.
Objective: We assessed the association between early HIV medical care interruption (MCI) and the development of AIDS-defining events (ADEs), serious non-AIDS events (SNAEs), and death among people with HIV (PWH) from the CoRIS cohort.
Design: We included antiretroviral-naive individuals aged at least 18 years at enrollment, recruited between 1 January 2004 and 30 May 2021, and followed-up until 30 November 2023.
Methods: Early MCI was defined as a time interval over 15 months between two consecutive visits, where the first of these visits occurred within the first 15 months of enrollment.
Retinal Microvascular Biomarker Assessment With Automated Algorithm and Semiautomated Software in the Montrachet Dataset.
Transl Vis Sci Technol
March 2025
Ophthalmology Department, Dijon University Hospital, Dijon, France.
Purpose: To compare automated and semiautomated methods for the measurement of retinal microvascular biomarkers: the automated retinal vascular morphology (AutoMorph) algorithm and the Singapore "I" Vessel Assessment (SIVA) software.
Methods: Analysis of retinal fundus photographs centered on optic discs from the population-based Montrachet Study of adults aged 75 years and older. Comparison and agreement evaluation with intraclass correlation coefficients (ICCs) between SIVA and AutoMorph measures of the central retinal venular and arteriolar equivalent, arteriolar-venular ratio, and fractal dimension.
