Macular degeneration (MD), which affects the central visual field including the fovea, has a profound impact on acuity and oculomotor control. We used a motion extrapolation task to investigate the contribution of various factors that potentially impact motion estimation, including the transient disappearance of the target into the scotoma, increased position uncertainty associated with eccentric target positions, and increased oculomotor noise due to the use of a non-foveal locus for fixation and for eye movements. Observers performed a perceptual baseball task where they judged whether the target would intersect or miss a rectangular region (the plate).

Cardiac amyloidosis (CA) is an infiltrative disease that results from the deposition of amyloid fibrils in the myocardium, resulting in restrictive cardiomyopathy. The amyloid fibrils are predominantly derived from two parent proteins, immunoglobulin light chain (AL) and transthyretin (ATTR), and ATTR is further classified into hereditary (ATTRv) and wild-type (ATTRwt) based on the presence or absence, respectively, of a mutation in the transthyretin gene. Once thought to be a rare entity, CA is increasingly recognized as a significant cause of heart failure due to improved clinical awareness and better diagnostic imaging.

Implicit solvation models permit the approximate description of solute-solvent interactions, where water is the most often considered solvent due to its relevance in biological systems. The use of other solvents is less common but is relevant for applications such as in nuclear magnetic resonance (NMR) or chromatography. As an example, chloroform is commonly used in anisotropic NMR to measure residual dipolar couplings (RDCs) of chiral analytes weakly aligned by an alignment medium.

Reviews of the effectiveness of medicinal cannabis for chronic pain vary in their conclusions. IASP has identified that a key missing evidence in this debate is data from observational cohort studies, analyzed with comparative effectiveness methods. In a medically supervised context to the use of marijuana for chronic pain, we identified 440 patients certified for medical marijuana by pain specialists in a single healthcare system.

Background: Web-first multimode survey protocols increase HCAHPS survey response rates and representativeness but may result in different HCAHPS scores because of survey mode effects and selective email address availability. A variable absent from many patient-mix adjustment models that may result in more positive patient experiences is whether the hospital admission was planned; adjustment for planned stays may better measure hospital performance.

Objectives: Develop adjustments for new Web-first survey protocols and planned admissions to facilitate comparisons across hospitals.

Objectives: This longitudinal experimental study aimed to profile audiometric hearing loss, explore the feasibility and efficacy of low-cost hearing devices, and examine their social and emotional impact on participants in South Sudan, a low-resource humanitarian setting.

Design: We performed pure tone hearing screenings on adults with self-reported hearing disability, randomly providing eligible participants with one of two inexpensive devices-Asana Pro 800, a non-customizable hearing device fit unilaterally, or the Super Ear SE9000, a hand-held amplifier with headphones given one per individual.

Study Sample: Between October 2022 and January 2023, 142 adults underwent hearing screening at the Juba Teaching Hospital ENT clinic, of whom 19 eligible individuals were provided with hearing devices.

Multifunctional devices based on van der Waals heterojunctions have drawn significant attention owing to their portable size, low power consumption and various application scenarios. However, high fabrication equipment requirements, complex device structures and limited operating conditions hinder their potential value. Herein, multifunctional UV photodetect-memristors based on GaS/graphene/GaN van der Waals heterojunctions area selective deposition have been proposed for the first time.

Objective: High body mass index (BMI) may reduce ulcerative colitis (UC) treatment efficacy. Etrasimod is an oral, once-daily (QD), selective sphingosine 1-phosphate (S1P)1,4,5 receptor modulator for the treatment of moderately to severely active UC. This post hoc analysis assessed treatment outcomes according to BMI in ELEVATE UC 52 and ELEVATE UC 12.

Heteropolar two-dimensional materials, including hexagonal boron nitride (hBN), are promising candidates for seawater desalination and osmotic power harvesting, but previous simulation studies have considered bare, unterminated nanopores in molecular dynamics (MD) simulations. There is presently a lack of force fields to describe functionalized nanoporous hBN in aqueous media. To address this gap, we conduct density functional theory (DFT)-based ab initio MD simulations of hBN nanopores surrounded by water molecules.

Transcriptome-Wide Association Study Identified Novel Blood Tissue Gene Biomarkers for Prostate Cancer Risk.

Prostate

January 2025

Cancer Epidemiology Division, Population Sciences in the Pacific Program, University of Hawaii Cancer Center, University of Hawaii at Manoa, Honolulu, Hawaii, USA.

Objective: A number of susceptibility genes in prostate tissue have been identified to be associated with prostate cancer (PCa) risk. However, the reported genes based on assessing prostate tissue could not fully explain PCa genetic susceptibility. It is believed that genes functioning in the immune system may fill in the gap of some missing heritability.

Purpose: This qualitative study assessed internet access and use, barriers and facilitators to participating in digital health interventions or programs, and the engagement experience in virtual versus in-person health interventions among rural adults and rural cancer survivors.

Methods: Rural adults (n = 10) and rural cancer survivors (n = 10) were recruited from previous studies to participate in an in-depth interview. The interview guide contained eight open-ended questions related to participation in technology-based programs.

As the main inhibitory neurotransmission system, the GABAergic system poses an interesting yet underutilized target for molecular brain imaging. While PET imaging of postsynaptic GABAergic neurons has been accomplished using radiolabeled benzodiazepines targeting the GABA receptor, the development of presynaptic radioligands targeting GABA transporter 1 (GAT1) has been unsuccessful thus far. Therefore, we developed a novel GAT1-addressing radioligand and investigated its applicability as a PET tracer in rodents.

Collaboration between occupational therapists and speech-language pathologists is crucial in stroke rehabilitation to effectively manage the complex challenges patients often experience after stroke. This article describes a two-hour, case-based interprofessional education (IPE) stroke workshop that required 67 graduate occupation therapy (OT) and speech-language pathology (SLP) students to collaboratively solve a case study related to stroke. Students used a survey to self-assess their interprofessional collaborative practice before and after participating in the workshop and completed a reflection journal.

Herpes simplex virus (HSV) infection is one of the most prevalent viral infections worldwide. In general, host immunity is sufficient to clear viral shedding and recurrences, although it is insufficient to prevent subsequent virologic reactivations. In immunocompromised patients, prolonged and difficult-to-treat HSV infections may develop.
