International workshop: what is needed to ensure outcome measures for Rett syndrome are fit-for-purpose for clinical trials? June 7, 2023, Nashville, USA.

Introduction: The clinical, research and advocacy communities for Rett syndrome are striving to achieve clinical trial readiness, including having fit-for-purpose clinical outcome assessments. This study aimed to (1) describe psychometric properties of clinical outcome assessment for Rett syndrome and (2) identify what is needed to ensure that fit-for-purpose clinical outcome assessments are available for clinical trials.

Methods: Clinical outcome assessments for the top 10 priority domains identified in the Voice of the Patient Report for Rett syndrome were compiled and available psychometric data were extracted.

Evolution of Diagnostic Medical Physics Enterprise.

The roles and responsibilities of radiation safety officers (RSO), medical health physicists (MHP) and diagnostic medical physicists (DMP) have evolved significantly over the past 20 years. With the availability of enterprise software systems and aggregated data platforms for various radiologic healthcare systems, the roles of these professions are expanding beyond their original scopes in managing the Radioactive Materials License (RSO, MHP) and Machine Specific Physics Testing (DMP). Workers in medical radiation safety are transitioning from siloed workers working within their specific disciplines as new emerging technology and clinical care require these roles to evolve.

Stem cell expressed CXCR4 regulates tissue composition in the vomeronasal organ.

The vomeronasal organ (VNO) detects signaling molecules that often prompt innate behaviors such as aggression and reproduction. Vomeronasal sensory neurons, classified into apical and basal lineages based on receptor expression, have a limited lifespan and are continuously replaced from a common stem cell niche. Using a combination of single-cell RNA sequencing data, immunofluorescence staining, and lineage tracing, we identified CXCR4 expression in proliferative stem cells and the basal neuronal lineage.

Effects of luteinizing hormone receptor activation in immortalized neoplastic canine T lymphocytes.

Objective: The expression of luteinizing hormone (LH) receptors has been reported in canine nonneoplastic and neoplastic lymphocytes. This study aimed to determine the effect of LH receptor activation in neoplastic canine T lymphocytes.

Methods: Cell lines (CLC, CLK, EMA) derived from 3 dogs with primary T-cell lymphoma were used.

Association of hearing, vision, and dual sensory impairment and risk of Alzheimer's disease: a nested case-control study.

Background: Hearing impairment is a known risk factor for Alzheimer's disease (AD), although less is known about vision impairment or dual sensory impairment (DSI) as risk factors for AD. We studied the association between diagnosed hearing impairment, visual impairment, or DSI, and the risk of AD.

Method: The Medication use and Alzheimer's disease study (MEDALZ) is a register-based nested case-control study including 70,718 community-dwelling persons diagnosed with incident AD in 2005-2011 in Finland and their 282,845 matched controls.
