Differential lipid signaling from CD4 and CD8 T cells contributes to type 1 diabetes development.

Introduction: We reported that Ca-independent phospholipase Aβ (iPLAβ)-derived lipids (iDLs) contribute to type 1 diabetes (T1D) onset. As CD4 and CD8 T cells are critical in promoting β-cell death, we tested the hypothesis that iDL signaling from these cells participates in T1D development.

Methods: CD4 and CD8 T cells from wild-type non-obese diabetic () and .

Safety and Efficacy of Axon Therapy (SEAT Study), Utilizing Magnetic Peripheral Nerve Stimulation (mPNS) for Treatment of Neuropathic Pain.

Background: Many of the current treatments for chronic neuropathic pain have variable effectiveness and known side effects. Given the prevalence of this type of intractable pain (3-17% of general population), additional therapeutic non-invasive approaches are desired. Magnetic Peripheral Nerve Stimulation (mPNS) delivered at 0.

Antidepressant Medication Use for Treatment of Chronic Ocular Pain.

Chronic ocular pain (COP) is a leading cause of eye care visits in the US and has a substantial impact on quality of life and visual functioning. Although many conditions underlie COP, such as dry eye disease or post-herpetic neuralgia, some people experience pain without significant ocular signs on examination or known risk factors (eg, traumatic injury). Antidepressant medications that act primarily on the central nervous system, such as tricyclic antidepressants and serotonin and norepinephrine reuptake inhibitors, are often used to treat patients with COP, but a recent Cochrane review and network meta-analysis investigating 25 different antidepressants concluded that only two serotonin and norepinephrine reuptake inhibitors, have sufficient data to support their use in chronic pain.

The Opinion of Healthcare Professionals About a Proposed European Registry of Neuromodulation for Chronic Pain: An Online Survey.

Introduction: During the last decade, the complementary value of real-world data (through registries or medical records) and data from randomized clinical trials has been recognized as increasingly important. In the field of neuromodulation, only a few industry-independent nationwide neuromodulation registries are available. The interest in creating a European registry has increased but without a successful result.

Update on Clinical Trial Endpoints in Gene Therapy Trials for Inherited Retinal Diseases.

Inherited retinal diseases (IRDs) encompass a wide spectrum of rare conditions characterized by diverse phenotypes associated with hundreds of genetic variations, often leading to progressive visual impairment and profound vision loss. Multiple natural history studies and clinical trials exploring gene therapy for various IRDs are ongoing. Outcomes for ophthalmic trials measure visual changes in three main categories-structural, functional, and patient-focused outcomes.

The role of 6-phosphogluconate dehydrogenase in vascular smooth muscle cell phenotypic switching and angioplasty-induced intimal hyperplasia.

Background: Restenosis poses a significant challenge for individuals afflicted with peripheral artery diseases, often leading to considerable morbidity and necessitating repeated interventions. The primary culprit behind the pathogenesis of restenosis is intimal hyperplasia (IH), in which the hyperproliferative and migratory vascular smooth muscle cell (VSMC) accumulate excessively in the tunica intima. 6-Phosphogluconate dehydrogenase (6PGD), sometimes referred to as PGD, is one of the critical enzymes in pentose phosphate pathway (PPP).

Analysis of Circadian Clock Gene Expression in Human Skin Explants.

Many aspects of skin biochemistry and physiology are known to vary over the course of the 24-hour day. Traditional approaches to study circadian rhythms in the skin have employed rodents or human subjects, which limit the experimental variables that can be studied. Although explants derived from discarded surgical skin are a commonly used model in the skin biology field, circadian rhythms have yet to be examined ex vivo.

Sexual Dimorphism in the Musculoskeletal System: Sex Hormones and Beyond.

Mounting evidence indicates that whereas some fundamental aspects of bone cell differentiation and function are similar in females and males, there is a clear contribution of sex/gender on the effects of signaling molecules on bone mass and strength and, consequently, on the effects of pharmacologic approaches to treat skeletal disorders. However, until recently, most studies were designed and performed using only 1 sex, resulting in a scarcity of published information on sexual dimorphism of the musculoskeletal system, including the mandible/masticatory muscles and the axial and appendicular bones and skeletal muscles. Further, it is now recognized that scientific rigor requires the study of both males and females.

A novel computational pathology approach for identifying gene signatures prognostic of disease-free survival for papillary thyroid carcinomas.

Introduction: Papillary thyroid carcinoma (PTC) is the most prevalent form of thyroid cancer, with the classical and follicular variants representing most cases. Despite generally favorable prognoses, approximately 10% of patients experience recurrence post-surgery and radioactive iodine therapy. Attempts to stratify risk of recurrence have relied on gene expression-based prognostic and predictive signatures with a focus on mutations of well-known driver genes, while hallmarks of tumor morphology have been ignored.

Quality and access outcomes in 2 Veterans Health Administration facilities with fidelity to the comprehensive medication management framework.

Purpose: Utilization of clinical pharmacists providing comprehensive medication management (CMM) has been shown to improve the quadruple aim of healthcare. Lack of fidelity surrounding CMM practice standardization components has led to heterogeneity in interpretation of clinical pharmacist outcomes. We compared 2 Veterans Health Administration (VHA) facilities with the patient-aligned care team (PACT) Platinum Practice designation in terms of clinical pharmacist practitioner (CPP) access and care quality relative to national CPP averages.

Effects of therapeutically approved individual bile acids on the development of metabolic dysfunction-associated steatohepatitis a low bile acid mouse model.

Bile acid (BA) signaling dysregulation is an important etiology for the development of metabolic dysfunction-associated steatotic liver disease (MASLD). As diverse signaling molecules synthesized in the liver by pathways initiated with CYP7A1 and CYP27A1, BAs are endogenous modulators of farnesoid x receptor (FXR). FXR activation is crucial in maintaining BA homeostasis, regulating lipid metabolism, and suppressing inflammation.

Uptake of Cancer Genetic Services for Chatbot vs Standard-of-Care Delivery Models: The BRIDGE Randomized Clinical Trial.

Importance: Increasing numbers of unaffected individuals could benefit from genetic evaluation for inherited cancer susceptibility. Automated conversational agents (ie, chatbots) are being developed for cancer genetics contexts; however, randomized comparisons with standard of care (SOC) are needed.

Objective: To examine whether chatbot and SOC approaches are equivalent in completion of pretest cancer genetic services and genetic testing.

Lysophosphatidic Acid Signaling in the Gastrointestinal System.

The intestinal epithelium undergoes continuous homeostatic renewal to conduct the digestion and absorption of nutrients. At the same time, the intestinal epithelial barrier separates the host from the intestinal lumen, preventing systemic infection from enteric pathogens. To maintain homeostasis and epithelial functionality, stem cells, which reside in the base of intestinal crypts, generate progenitor cells that ultimately differentiate to produce an array of secretory and absorptive cells.
