Disparities in care and outcomes for adolescent and young adult lymphoma patients.

Though survival outcomes among adolescents and young adults (AYAs) with lymphoma have improved over the last three decades, socially vulnerable populations including non-White, low-income, and publicly insured groups continue to trail behind on survival curves. These disparities, while likely the result of both biological and non-biological factors, can be largely attributed to inequities in care over the full cancer continuum. Nationally representative studies have demonstrated that from diagnosis through therapy and into long-term survivorship, socially vulnerable AYAs with lymphoma face barriers to care that impact their short and long-term survival.

Reliability of the NACC Telephone-administered Neuropsychological Battery (T-cog) and Montreal Cognitive Assessment for participants in the USC ADRC.

Introduction: Restrictions during the COVID-19 pandemic necessitated remote administration of neuropsychological testing. We assessed the test-retest reliability for a telephone-administered cognitive battery, recommended for use in the National Institute on Aging Alzheimer's Disease Research Center (ADRC).

Methods: 64 participants in the University of Southern California ADRC clinical core underwent repeat telephone evaluation using the T-cog Neuropsychological Battery.

3D bioprinting of an implantable xeno-free vascularized human skin graft.

Bioengineered tissues or organs produced using matrix proteins or components derived from xenogeneic sources pose risks of allergic responses, immune rejection, or even autoimmunity. Here, we report successful xeno-free isolation, expansion, and cryopreservation of human endothelial cells (EC), fibroblasts (FBs), pericytes (PCs), and keratinocytes (KCs). We further demonstrate the bioprinting of a human skin substitute with a dermal layer containing xeno-free cultured human EC, FBs, and PCs in a xeno-free bioink containing human collagen type I and fibronectin layered in a biocompatible polyglycolic acid mesh and subsequently seeded with xeno-free human KCs to form an epidermal layer.

Sound-guided assessment and localization of pulmonary air leak.

Pulmonary air leak is the most common complication of lung surgery, with air leaks that persist longer than 5 days representing a major source of post-surgery morbidity. Clinical management of air leaks is challenging due to limited methods to precisely locate and assess leaks. Here, we present a sound-guided methodology that enables rapid quantitative assessment and precise localization of air leaks by analyzing the distinct sounds generated as the air escapes through defective lung tissue.

Models of depressive pseudoamnestic disorder.

Objective: Little effort has been made in the past to validate depressive pseudodementia based on hypothesis-driven approaches. We extended this concept to individuals with amnestic Mild Cognitive Impairment and Major Depression, that is, pseudodepressive amnestic disorder. We tested two hypotheses consistent with the presentations and mechanisms associated with this potential syndrome: improvements in cognition would be significantly correlated with improvements in depression after treatment (Hypothesis 1), and if not confirmed, the presence of such an association could be identified once moderator variables were taken into account (Hypothesis 2).

COVID-19 infection in an infant with cystic fibrosis: A case report and possible therapeutic effect of hypertonic saline.

Pulmonary infections represent the major causes of morbidity and mortality in cystic fibrosis (CF). Here, we report a 3-month-old infant with pancreatic insufficient CF was hospitalized with positive RT-PCR test for COVID-19. He was treated successfully.

Clinicians' perspectives on the implementation of patient decision aids in the emergency department: A qualitative interview study.

Objective: Decision aids (DAs) are tools to facilitate and standardize shared decision making (SDM). Although most emergency clinicians (ECs) perceive SDM appropriate for emergency care, there is limited uptake of DAs in clinical practice. The objective of this study was to explore barriers and facilitators identified by ECs regarding the implementation of DAs in the emergency department (ED).

Deep learning improves utility of tau PET in the study of Alzheimer's disease.

Introduction: Positron emission tomography (PET) imaging targeting neurofibrillary tau tangles is increasingly used in the study of Alzheimer's disease (AD), but its utility may be limited by conventional quantitative or qualitative evaluation techniques in earlier disease states. Convolutional neural networks (CNNs) are effective in learning spatial patterns for image classification.

Methods: 18F-MK6240 (n = 320) and AV-1451 (n = 446) PET images were pooled from multiple studies.

Milestones comparisons from residency to pediatric emergency medicine fellowship: Resetting expectations.

Background: Pediatric emergency medicine (PEM) fellowships accept trainees who have completed a residency in either emergency medicine (EM) or pediatrics and have adopted 17 subcompetencies with accompanying set of milestones from these two residency programs. This study aims to examine the changes in milestone scores among common subcompetencies from the end of EM or pediatrics residency to early PEM fellowship and evaluates time to reattainment of scores for subcompetencies in which a decline was noted.

Methods: This is a national, retrospective cohort study of trainees enrolled in PEM fellowship programs from July 2014 to June 2018.

Milestone achievements in a national sample of pediatric emergency medicine fellows: impact of primary residency training.

Background: Pediatric emergency medicine (PEM) fellowships recruit trainees from both pediatric and emergency medicine (EM) residencies. The Accreditation Council for Graduate Medical Education (ACGME) defines separate training pathways for each. The 2015 PEM milestones reflect a combination of subcompetencies from the two residencies.

RFA and benign thyroid nodules: Review of the current literature.

Unlabelled: Benign thyroid nodules (BTNs) are commonly found in the general population. They are usually asymptomatic and their incidence has increased as a result of wide-spread use of ultrasound. Benign nodules are typically monitored clinically until they increase in size, resulting in compressive symptoms warranting surgery.

The AT(N) framework for Alzheimer's disease in adults with Down syndrome.

The National Institute on Aging in conjunction with the Alzheimer's Association (NIA-AA) recently proposed a biological framework for defining the Alzheimer's disease (AD) continuum. This new framework is based upon the key AD biomarkers (amyloid, tau, neurodegeneration, AT[N]) instead of clinical symptoms and represents the latest understanding that the pathological processes underlying AD begin decades before the manifestation of symptoms. By using these same biomarkers, individuals with Down syndrome (DS), who are genetically predisposed to developing AD, can also be placed more precisely along the AD continuum.

Sex differences in risk of Alzheimer's disease in adults with Down syndrome.

Introduction: Adults with Down syndrome (DS) older than 40 have Alzheimer's disease (AD) neuropathology and high risk for dementia, but little is known about the relationship of sex to AD risk in this population.

Methods: Using nonparametric methods and Cox proportional hazards models we analyzed differences in incidence of dementia, by sex, presence of an apolipoprotein E () ε4 or ε2 allele, and dementia duration and decline in 246 adults over 40 with DS.

Results: There was no significant sex difference in risk of AD or rate of cognitive decline.

: A distal myopathy with polyglucosan bodies.

Mutations in glycogenin-1 () cause an adult-onset polyglucosan body myopathy. We report here a patient presenting with late-onset distal myopathy. We wish to highlight this rare clinical phenotype of -related myopathy and the histological clues leading to its diagnosis.

Longitudinal health-related quality of life in first-line treated patients with chronic lymphocytic leukemia: Results from the Connect CLL Registry.

Health-related quality of life (HRQoL) in patients with chronic lymphocytic leukemia (CLL) is important in guiding treatment decisions. However, the impact of CLL treatment initiation on HRQoL is unclear. We assessed HRQoL using the FACT-Leu and EQ-5D-3L questionnaires in the Connect CLL Registry, a large, US-based, multicenter, prospective observational study of CLL patients enrolled between 2010 and 2014, prior to the introduction of novel therapies.

Proteomic profiles for Alzheimer's disease and mild cognitive impairment among adults with Down syndrome spanning serum and plasma: An Alzheimer's Biomarker Consortium-Down Syndrome (ABC-DS) study.

Introduction: Previously generated serum and plasma proteomic profiles were examined among adults with Down syndrome (DS) to determine whether these profiles could discriminate those with mild cognitive impairment (MCI-DS) and Alzheimer's disease (DS-AD) from those cognitively stable (CS).

Methods: Data were analyzed on n = 305 (n = 225 CS; n = 44 MCI-DS; n = 36 DS-AD) enrolled in the Alzheimer's Biomarker Consortium-Down Syndrome (ABC-DS).

Results: Distinguishing MCI-DS from CS, the serum profile produced an area under the curve (AUC) = 0.

Use of daratumumab in high risk multiple myeloma: A meta-analysis.

Daratumumab is approved for use in newly diagnosed and relapsed/refractory multiple myeloma (MM), however the patients most likely to benefit from its addition to standard anti-myeloma therapy is unclear. This meta-analysis included 2340 newly diagnosed MM patients (1982 with standard risk and 358 with high risk cytogenetics) and 673 patients with relapsed/refractory MM (513 with standard risk and 160 with high risk cytogenetics) to assess which cytogenetic subgroups derived PFS benefit from Daratumumab. Studies included were the CASSIOPEIA, MAIA and ALCYONE (for newly diagnosed MM) and the CASTOR and POLLUX trials (for relapsed/refractory MM).

Proteomic profiles of incident mild cognitive impairment and Alzheimer's disease among adults with Down syndrome.

Introduction: We sought to determine if proteomic profiles could predict risk for incident mild cognitive impairment (MCI) and Alzheimer's disease (AD) among adults with Down syndrome (DS).

Methods: In a cohort of 398 adults with DS, a total of n = 186 participants were determined to be non-demented and without MCI or AD at baseline and throughout follow-up; n = 103 had incident MCI and n = 81 had incident AD. Proteomics were conducted on banked plasma samples from a previously generated algorithm.

Proteomic profiles of prevalent mild cognitive impairment and Alzheimer's disease among adults with Down syndrome.

Introduction: We sought to determine if a proteomic profile approach developed to detect Alzheimer's disease (AD) in the general population would apply to adults with Down syndrome (DS).

Methods: Plasma samples were obtained from 398 members of a community-based cohort of adults with DS. A total of n = 186 participants were determined to be non-demented and without mild cognitive impairment (MCI) at baseline and throughout follow-up; n = 50 had prevalent MCI; n = 42 had prevalent AD.

Multiple System Atrophy With Predominant Striatonigral Degeneration and TAR DNA-Binding Protein of 43 kDa Pathology: An Unusual Variant of Multiple System Atrophy.

Background: The pathological hallmark in MSA is oligodendrocytic glial cytoplasmic inclusions (GCIs) containing α-synuclein, in addition to neuronal loss and astrogliosis especially involving the striatonigral and olivopontocerebellar systems. Rarely, TAR DNA-binding protein of 43 kDa (TDP-43), a component of ubiquitinated inclusions observed mainly in amyotrophic lateral sclerosis and frontotemporal lobar degeneration has been demonstrated in cases of MSA and, more recently, was shown to colocalize with α-synuclein pathology in GCIs in 2 patients.

Methods: A 66-year-old woman presented with a syndrome characterized by spasticity, dysautonomia, bulbar dysfunction, and parkinsonism.
