Association of Hearing Loss with Physical, Social, and Mental Activity Engagement.

This article aims to evaluate a hearing loss intervention versus an aging education intervention on activity engagement in the Aging and Cognitive Health Evaluation in Elders pilot (ACHIEVE-P). Forty adults (70-84 years) with hearing loss recruited from the Atherosclerosis Risk in Communities Study and de novo participated. Participants were randomized 1:1 to a best practices hearing intervention or a successful aging intervention. Hearing was measured with pure-tone audiometry. The Community Healthy Activities Model Program for Seniors questionnaire measured self-reported time engaging in activities at baseline and 6-month follow-up. At baseline, greater hearing loss was associated with reduced time per week on mental activities (-3.0 hours per 10 dB of hearing loss, 95% confidence interval: -5.8, -0.2). Mental activity engagement increased (mean: +1.3 hours, SD = 6.6) for the hearing intervention group but decreased (mean: -1.1 hours, SD = 4.8) for the aging education group (Cohen's d : 0.41). Hearing loss may be associated with reduced engagement in mental activities. Whether hearing loss treatment impacts activity will be studied in the full-scale ACHIEVE trial.

Platelet-T cell aggregates in lung cancer patients: Implications for thrombosis.

Platelet-leukocyte aggregates (PLAs) are associated with increased thrombosis risk. The influence of PLA formation is especially important for cancer patients, since thrombosis accounts for approximately 10% of cancer-associated deaths. Our objective was to characterize and quantify PLAs in whole blood samples from lung cancer patients compared to healthy volunteers with the intent to analyze PLA formation in the context of lung cancer-associated thrombosis. Consenting lung cancer patients (57) and healthy volunteers (56) were enrolled at the Dana Cancer Center at the University of Toledo Health Science Campus. Peripheral blood samples were analyzed by flow cytometry. Patient medical history was reviewed through electronic medical records. Most importantly, we found lung cancer patients to have higher percentages of platelet-T cell aggregates (PTCAs) than healthy volunteers among both CD4+ T lymphocyte and CD8+ T lymphocyte populations. Our findings demonstrate that characterization of PTCAs may have clinical utility in differentiating lung cancer patients from healthy volunteers and stratifying lung cancer patients by history of thrombosis.
