Targeted long-read sequencing to quantify methylation of the C9orf72 repeat expansion.

Background: The gene C9orf72 harbors a non-coding hexanucleotide repeat expansion known to cause amyotrophic lateral sclerosis and frontotemporal dementia. While previous studies have estimated the length of this repeat expansion in multiple tissues, technological limitations have impeded researchers from exploring additional features, such as methylation levels.

Methods: We aimed to characterize C9orf72 repeat expansions using a targeted, amplification-free long-read sequencing method.

Health System Purchasing Professionals' Approaches to Considering Equity in Procurement.

Background: Continuing data on racial bias in pulse oximeters and artificial intelligence has sparked calls for health systems to drive innovation against racial bias in healthcare device and artificial intelligence markets by incorporating equity concerns explicitly into purchasing decisions.

Research Question: How do healthcare purchasing professionals integrate equity concerns into purchasing decision-making?

Study Design And Methods: Between 8/2023-3/2024, we conducted semi-structured interviews via videoconferencing with healthcare purchasing professionals about purchasing processes for pulse oximeters and other devices-and whether and where equity concerns arise in decision-making. An abductive approach was used to analyze perspectives on how equity and disparity concerns are currently integrated into healthcare purchasing decision-making.

Painless Aortic Syndrome in a Patient with Syncope and Globus Sensation: A Case Report.

Introduction: Aortic dissection is a devastating clinical entity with a variety of presentations and requires prompt recognition and management. To our knowledge this is the first reported case of a patient who presented with a globus sensation and was diagnosed with an aortic dissection prior to clinical deterioration.

Case Report: The patient presented with an episode of near-syncope and globus sensation.

Effect of the COVID-19 pandemic on unmet healthcare needs after hospital discharge in acute respiratory failure survivors: A multicenter prospective cohort study.

Survivors of acute respiratory failure (ARF) have complex healthcare needs postdischarge, frequently resulting in unmet needs. This prospective multicenter study explores the association between COVID-19 status and unmet healthcare needs in survivors of ARF following hospital discharge. We analyzed patient characteristics and unmet healthcare needs by COVID-19 status using a multivariable regression model with propensity weights.

Laminar Fluid Ejection for Olfactory Drug Delivery: A Proof of Concept Study.

Focal intranasal drug delivery to the olfactory cleft is a promising avenue for pharmaceuticals targeting the brain. However, traditional nasal sprays often fail to deliver enough medication to this specific area. We present a laminar fluid ejection (LFE) method for precise delivery of medications to the olfactory cleft.
