Background: The aim of this study is to present the clinical outcome of endovascular aneurysm sealing (EVAS) with the Nellix endoprosthesis in patients with abdominal aortic aneurysms treated in our institution.
Methods: This is a retrospective, single center, observational cohort study. A departmental database was interrogated to extract demographics, clinical information, and outcome of all patients treated with EVAS between December 2013 and December 2015. Outcome measures included technical success (successful device deployment and absence of any endoleak at completion angiography), mortality, major complications, incidence of endoleaks, aneurysm rupture, and reintervention.
Results: Sixty-five patients (49 men) with a mean (standard deviation) age of 78 (6.9) years were successfully treated with EVAS, with no 30-day mortality. The cohort included 1 patient with ruptured aneurysm, 9 patients with late complications of previous aortoiliac repairs (2 open, 7 endovascular), and 4 patients who required a total of 9 visceral chimneys for juxtarenal aneurysms. Six patients (9%) suffered major postoperative complications and 4 (6%) required intervention. There were no early or late endoleaks or aneurysm ruptures. After a median (range) follow-up of 12 (0-24) months, there was no aneurysm-related mortality; 2 patients (3%) required late aneurysm-related interventions.
Conclusions: EVAS can be performed with good outcomes up to 2 years postoperatively. Longer follow-up on larger cohorts is needed to prove the efficacy of this technique.

Clinical Informatics and Health Outcomes Research Group, Nuffield Department of Primary Care Health Sciences, University of Oxford, Oxford, United Kingdom.
Background: There are gaps in our understanding of the clinical characteristics and disease burden of the respiratory syncytial virus (RSV) among community-dwelling adults. This is in part due to a lack of routine testing at the point of care. More data would enhance our assessment of the need for an RSV vaccination program for adults in the United Kingdom.

JAMA Netw Open
January 2025
University Hospitals Cleveland Medical Center, Case Western Reserve University School of Medicine, Cleveland, Ohio.
Importance: A substantial number of individuals worldwide experience long COVID, or post-COVID condition. Other postviral and autoimmune conditions have a female predominance, but whether the same is true for long COVID, especially within different subgroups, is uncertain.
Objective: To evaluate sex differences in the risk of developing long COVID among adults with SARS-CoV-2 infection.
Medicaid Spending in Coordination-Only Dual-Eligible Special Needs Plans.
JAMA Netw Open
January 2025
Department of Population Health Sciences, Duke University School of Medicine, Durham, North Carolina.
Importance: More than 4 million Medicare beneficiaries have enrolled in dual-eligible Special Needs Plans (D-SNPs), and coordination-only D-SNPs are common. Little is known about the impact of coordination-only D-SNPs on Medicaid-covered services and spending, including long-term services and supports, which are financed primarily by Medicaid.
Objective: To evaluate changes in Medicaid fee-for-service (FFS) spending before and after new enrollment in coordination-only D-SNPs vs new enrollment in non-D-SNP Medicare Advantage (MA) plans among community-living beneficiaries enrolled in both Medicare and North Carolina Medicaid.
External Validation of the Walter Index for Posthospitalization Mortality Prediction in Older Adults.
JAMA Netw Open
January 2025
Division of Geriatrics, School of Medicine, University of California San Francisco.
Importance: The Walter Index is a widely used prognostic tool for assessing 12-month mortality risk among hospitalized older adults. Developed in the US in 2001, its accuracy in contemporary non-US contexts is unclear.
Objective: To evaluate the external validity of the Walter Index in predicting posthospitalization mortality risk in Brazilian older adult inpatients.
Cerebral Microbleeds and Amyloid Pathology Estimates From the Amyloid Biomarker Study.
JAMA Netw Open
January 2025
Alzheimer Center Limburg, Department of Psychiatry and Neuropsychology, School for Mental Health and Neuroscience, Maastricht University, Maastricht, the Netherlands.
Importance: Baseline cerebral microbleeds (CMBs) and APOE ε4 allele copy number are important risk factors for amyloid-related imaging abnormalities in patients with Alzheimer disease (AD) receiving therapies to lower amyloid-β plaque levels.
Objective: To provide prevalence estimates of any, no more than 4, or fewer than 2 CMBs in association with amyloid status, APOE ε4 copy number, and age.
Design, Setting, And Participants: This cross-sectional study used data included in the Amyloid Biomarker Study data pooling initiative (January 1, 2012, to the present [data collection is ongoing]).
