Objective: To investigate β-amyloid and tau depositions using Pittsburgh compound B (PiB) positron emission tomography (PET) and AV1451 tau PET imaging in aging multiple sclerosis (MS) patients.
Methods: Patients with MS (n = 16) and controls (n = 80) matched for age, sex, and APOE ε4 status from the population-based Mayo Clinic Study of Aging who underwent PiB PET imaging were studied. Of these individuals, 12 patients with MS and 60 matching controls also underwent AV1451 tau PET. Cortical PiB and AV1451 standard uptake value ratios (SUVrs) from the entire cortex and previously determined Alzheimer disease (AD) signature regions in the same population were calculated for group comparisons and testing for associations with age.
Results: AD signature PiB SUVr (odds ratio [OR] [95% confidence interval (CI)] = 0.52 [0.27-0.98], p = 0.044), total cortical PiB SUVr (OR [95% CI] = 0.52 [0.28-0.99], p = 0.048), and the frequency of abnormal PiB SUVrs (OR [95% CI] = 0.10 [0.01-0.90], p = 0.040) were lower in MS than controls. Although AD-signature and total cortical AV1451 SUVrs were not different between the groups, the frequency of abnormal AV1451 SUVrs was higher (OR [95% CI] = 10.65 [1.10-103.35], p = 0.041) in MS than controls. The association of AD signature PiB SUVr with age was steeper in the controls compared to patients with MS (estimate [95% CI] = -0.14 [-0.023 to -0.006], p = 0.002). Similarly, the association of total cortical PiB SUVr with age was steeper in the controls compared to patients with MS (estimate [95% CI] = -0.13 [-0.021 to -0.005], p = 0.002). There was no difference in the association of AV1451 SUVr findings with age between the MS patients and controls.
Interpretation: Although both β-amyloid and tau are biomarkers of cognitive aging and AD, cortical β-amyloid deposition was lower in MS than age-matched controls, suggesting that some aspect of MS pathobiology retards the accumulation of β-amyloid but not the accumulation of tau.

Background: Inequities exist in pediatric surgical outcomes. Differential outcomes have been identified across racial groups, geography, and socioeconomic standing. However, the association between preferred language, interpreter use, and surgical outcomes is not well-studied in pediatric surgical literature.

Background: Leaving before medically advised (BMA) is a significant issue in the US healthcare system, leading to adverse health outcomes and increased costs. Despite previous research, multi-year studies using up-to-date nationwide emergency department (ED) data, are limited. This study examines factors associated with leaving BMA from EDs and trends over time, before and during the COVID-19 pandemic.

Purpose The present study aimed to clarify the distribution pattern of carcinoma associated fibroblasts (CAFs) across pancreatic ductal adenocarcinoma (PDAC) and its prognostic prediction value. Methods Data of two cohorts were retrospectively collected from consecutive patients who underwent primary pancreatic resection from January 2015 to December 2017. We used tumor specimens to screen out the most suitable markers for the spatial distribution analysis for CAFs subpopulations.

Allied prisoners of war (POWs) working on the Imperial Japanese Army's railroad from Thailand to Burma during 1943-1945 devised a blood transfusion service to rescue severely ill fellow prisoners who were otherwise unlikely to survive the war. Extant transfusion records (1,251 recipients, 1,189 donors) in ledger books held by the United Kingdom National Archives at Kew were accessed and analyzed. Survival to the end of the war in 1945 was determined from Commonwealth War Graves Commission records.
