Chronic stress results in long-term dynamic changes at multiple levels of the hypothalamic-pituitary-adrenal (HPA) axis resulting in stress axis dysregulation with long-term impacts on human and animal health. However, the underlying mechanisms and dynamics of altered of HPA axis function, in particular at the level of pituitary corticotrophs, during a period of chronic stress and in the weeks after its cessation (defined as "recovery") are very poorly understood. Here, we address the fundamental question of how a period of chronic stress results in altered anterior pituitary corticotroph function and whether this persists in recovery, as well as the transcriptomic changes underlying this.

People with epilepsy (PWE) stand to benefit significantly from increasing their physical activity, but promotion of physical activity is difficult in any population; a challenge compounded by the unique barriers encountered by PWE, especially those with drug-resistant epilepsy (DRE). This study explores the feasibility of a remotely delivered, 12-week aerobic exercise program based on social cognitive theory principles in adults with DRE. This line of research is nested within the Multiphase Optimization Strategy (MOST), a framework that emphasizes iterative early pilot work (preparation phase research), followed by iterative optimization phase research.

Article Synopsis
  • The study focuses on understanding how social determinants—nonmedical factors impacting health—affect the use of rehabilitation services, particularly after a stroke, which has been underexplored.
  • Researchers reviewed various models to create a framework for identifying and selecting area-level social determinant measures to better analyze their relationship with rehabilitation service utilization.
  • The communication also highlights the challenges faced during the research process and discusses potential future directions for studying the intersection of social determinants and rehabilitation.

Gluten proteins are storage proteins in wheat that exhibit a certain resistance to gastrointestinal digestion. To explore solutions to cope with accidental ingestion of gluten in individuals suffering from gluten-related disorders, it is essential to monitor the fate of gluten peptides in biological samples, , gastrointestinal juices, blood plasma or urine. In this work, we aimed at developing a mass spectrometry (MS)-based method for measuring gluten peptides in human duodenal fluids.

Background And Objectives: Anxiety and depression are highly prevalent and impactful in epilepsy. American Academy of Neurology quality measures emphasize anxiety and depression screening and quality of life (QOL) measurement, yet usual epilepsy care QOL and anxiety/depression outcomes are poorly characterized. The main objective was to assess 6-month QOL, anxiety and depression during routine care among adults with epilepsy and baseline anxiety or depression symptoms; these were prespecified secondary outcomes within a pragmatic randomized trial of remote assessment methods.

Background And Aims: Ultrasonography has shown that eosinophils accumulate in each segment of the esophageal mucosa in human EoE, ultimately promoting esophageal motility dysfunction; however, no mechanistic evidence explains how or why this accumulation occurs.

Methods: Quantitative PCR, ELISA, flow cytometry, immunostaining, and immunofluorescence analyses were performed using antibodies specific to the related antigens and receptors.

Results: In deep esophageal biopsies of EoE patients, eosinophils and mast cells accumulate adjacent to nerve cell-derived VIP in each esophageal segment.

In recent years, temperatures have increased globally, and nestlings of many bird species are likely regularly exposed to increased temperatures both pre- and postnatally. Even small increases in nest temperature during incubation affect offspring growth and survival in a variety of species, one cause of which is thought to be increased production of prooxidants in embryos and nestlings. Defences marshalled in response to this oxidative stress could, in turn, result in trade-offs that lead to reduced survival or growth.

Background: The purpose of this study was to develop a clinical support tool for osteoporosis clinic providers to support risk assessment and referrals for evidence-based exercise therapy programs.

Methods: A sequential Delphi method was used with a multidisciplinary group of national falls experts, to provide consensus on referral to exercise therapy for patients at risk for falls. The Delphi study included a primary research team, expert panel, and clinical partners to answer the questions: (1) "What patient characteristics are needed to develop a clinical support tool?"; (2) "What are the recommended exercise referrals for patients with osteoporosis at risk for falls?" The consensus process consisted of two rounds with 8 weeks between meetings.

In 2021, Research in Medical Education (RIME) celebrated 60 years of advancing scholarship in health professions education (HPE). At that time, the nation's educational institutions faced a public reckoning on the long-standing pandemic of racism that sweltered in their practices and policies, laid bare by COVID-19 and the Black Lives Matters movement. RIME responded with a mentorship program for minoritized early career HPE faculty, which aims to amplify their voices in settings where their experiences and contributions are frequently dampened.
