Mitochondrial Autophagy In Ischemic Aged Livers, Jae-Sung Kim, William C Chapman, Yiing Lin

2020-Current year OA Pubs

Mitochondrial autophagy (mitophagy) is a central catabolic event for mitochondrial quality control. Defective or insufficient mitophagy, thus, can result in mitochondrial dysfunction, and ultimately cell death. There is a strong causal relationship between ischemia/reperfusion (I/R) injury and mitochondrial dysfunction following liver resection and transplantation. Compared to young patients, elderly patients poorly tolerate I/R injury. Accumulation of abnormal mitochondria after I/R is more prominent in aged livers than in young counterparts. This review highlights how altered autophagy is mechanistically involved in age-dependent hypersensitivity to reperfusion injury.

Association Of Leukocyte Telomere Length With Perceived Physical Fatigability, Rain Katz, Emma L Gay, Allison L Kuipers, Joseph H Lee, Lawrence S Honig, Kaare Christensen, Mary F Feitosa, Mary K Wojczynski, Nancy W Glynn, Llfs Research Group

2020-Current year OA Pubs

BACKGROUND: Leukocyte telomere length (LTL) is a potential genomic marker of biological aging, but its relation to fatigability, a prognostic indicator of phenotypic aging (e.g., functional decline) is unknown. We hypothesized shorter LTL would predict greater perceived physical fatigability, but that this association would be attenuated by adjusting for chronological age.

METHODS: Two generations of participants (N = 1997; 309 probands, 1688 offspring) were from the Long Life Family Study (age = 73.7 ± 10.4, range 60-108, 54.4 % women), a longitudinal cohort study of aging. LTL was assayed at baseline. Perceived physical fatigability was measured 8.0 ± 1.1 years …

Radiotherapy For Elderly Patients With Glioblastoma: An Assessment Of Hypofractionation And Modern Treatment Techniques, Jennifer K. Matsui, Jiayi Huang, Et Al.

2020-Current year OA Pubs

Glioblastoma (GBM) is a disease with a poor prognosis. For decades, radiotherapy has played a critical role in the management of GBM. The standard of care radiation prescription is 60 Gy in 30 fractions, but landmark trials have historically excluded patients older than 70 years. Currently, there is considerable variation in the management of elderly patients with GBM. Shortened radiation treatment (hypofractionated) regimens have been explored since conventional treatment schedules are lengthy and many elderly patients have functional, cognitive, and social limitations. Clinical trials have demonstrated the effectiveness of hypofractionated radiotherapy (40 Gy in 15 fractions) to treat elderly or …

Multicenter, Randomized Trial Of A Bionic Pancreas In Type 1 Diabetes, Steven J Russell, Janet B Mcgill, Maamoun Salam, Julie M Silverstein, Samantha Adamson, Andrea Cedeno, Et Al.

2020-Current year OA Pubs

BACKGROUND: Currently available semiautomated insulin-delivery systems require individualized insulin regimens for the initialization of therapy and meal doses based on carbohydrate counting for routine operation. In contrast, the bionic pancreas is initialized only on the basis of body weight, makes all dose decisions and delivers insulin autonomously, and uses meal announcements without carbohydrate counting.

METHODS: In this 13-week, multicenter, randomized trial, we randomly assigned in a 2:1 ratio persons at least 6 years of age with type 1 diabetes either to receive bionic pancreas treatment with insulin aspart or insulin lispro or to receive standard care (defined as any insulin-delivery …

Exit Rates Of Accountable Care Organizations That Serve High Proportions Of Beneficiaries Of Racial And Ethnic Minority Groups, Sunny C Lin, Karen E Joynt Maddox, Andrew M Ryan, Nicholas Moloci, Addison Shay, John Malcolm Hollingsworth

2020-Current year OA Pubs

Importance: The Medicare Shared Savings Program provides financial incentives for accountable care organizations (ACOs) to reduce costs of care. The structure of the shared savings program may not adequately adjust for challenges associated with caring for patients with high medical complexity and social needs, a population disproportionately made up of racial and ethnic minority groups. If so, ACOs serving racial and ethnic minority groups may be more likely to exit the program, raising concerns about the equitable distribution of potential benefits from health care delivery reform efforts.

Objective: To evaluate whether ACOs with a high proportion of beneficaries of racial …

Perioperative Mental Health Intervention Bundle For Older Surgical Patients: Protocol For An Intervention Development And Feasibility Study, Joanna Abraham, Katherine J Holzer, Emily M Lenard, Kenneth E Freedland, Bethany R Tellor Pennington, Rachel C Wolfe, Theresa A Cordner, Ana A Baumann, Mary Politi, Michael Simon Avidan, Eric Lenze

2020-Current year OA Pubs

INTRODUCTION: The perioperative period is high risk for older adults. Depression and anxiety are common perioperative problems, frequently coexisting with cognitive impairment. Older patients with these conditions are more likely than younger patients to experience postoperative delirium, long hospital stays, poor quality of life and rehospitalisation. These experiences can, in turn, exacerbate anxiety and depressive symptoms. Despite these risks, little is known about how to treat perioperative anxiety and depression among older adults.

METHODS AND ANALYSIS: We designed a feasibility study of a perioperative mental health intervention bundle to improve perioperative mental health, specifically depression and anxiety. The overarching goals …

Normal Aging In Mice Is Associated With A Global Reduction In Cortical Spectral Power And Network-Specific Declines In Functional Connectivity, Asher J Albertson, Eric C Landsness, Michelle J Tang, Ping Yan, Hanyang Miao, Zachary P Rosenthal, Byungchan Kim, Joseph C Culver, Adam Q Bauer, Jin-Moo Lee

2020-Current year OA Pubs

Normal aging is associated with a variety of neurologic changes including declines in cognition, memory, and motor activity. These declines correlate with neuronal changes in synaptic structure and function. Degradation of brain network activity and connectivity represents a likely mediator of age-related functional deterioration resulting from these neuronal changes. Human studies have demonstrated both general decreases in spontaneous cortical activity and disruption of cortical networks with aging. Current techniques used to study cerebral network activity are hampered either by limited spatial resolution (e.g. electroencephalography, EEG) or limited temporal resolution (e.g., functional magnetic resonance imaging, fMRI). Here we utilize mesoscale imaging …

Ances, Dominantly Inherited Alzheimer Network

2020-Current year OA Pubs

"Brain-predicted age" quantifies apparent brain age compared to normative neuroimaging trajectories. Advanced brain-predicted age has been well established in symptomatic Alzheimer disease (AD), but is underexplored in preclinical AD. Prior brain-predicted age studies have typically used structural MRI, but resting-state functional connectivity (FC) remains underexplored. Our model predicted age from FC in 391 cognitively normal, amyloid-negative controls (ages 18-89). We applied the trained model to 145 amyloid-negative, 151 preclinical AD, and 156 symptomatic AD participants to test group differences. The model accurately predicted age in the training set. FC-predicted brain age gaps (FC-BAG) were significantly older in symptomatic AD and …
