Vitamin D Significantly Inhibits Carcinogenesis in the Mogp-TAg Mouse Model of Fallopian Tube Ovarian Cancer.

Epidemiological and observational studies suggest that vitamin D has potential for the chemoprevention of ovarian cancer. The anticancer effect of vitamin D in the fallopian tube epithelium (FTE), which is now thought to harbor the precursor cells for high grade ovarian cancer, is not known. The purpose of this study was to investigate whether vitamin D can inhibit carcinogenesis in the mogp-TAg fallopian tube (FT) ovarian cancer mouse model and examine underlying mechanisms.

In Vivo Contribution of Cyp24a1 Promoter Vitamin D Response Elements.

CYP24A1 is a multifunctional, P450 mitochondrial enzyme that catabolizes the vitamin D hormone (calcitriol, 1,25(OH)2D3), its precursor (calcifediol, 25(OH)D3), and numerous vitamin D metabolites. In the kidney, Cyp24a1 is induced by 1,25(OH)2D3 and fibroblast growth factor 23 (FGF23) and potently suppressed by PTH to control the circulating levels of 1,25(OH)2D3. Cyp24a1 is controlled by a pair of promoter proximal (PRO) vitamin D response elements (VDREs) that are aided by distal, downstream (DS) enhancers.

LAIR-1 and PECAM-1 function via the same signaling pathway to inhibit GPVI-mediated platelet activation.

Background: Inhibition of platelet responsiveness is important for controlling thrombosis. It is well established that platelet endothelial cell adhesion molecule-1 (PECAM-1) serves as a physiological negative regulator of platelet-collagen interactions. We recently demonstrated that leukocyte-associated immunoglobulin-like receptor-1 (LAIR-1) is a negative regulator of platelet production and reactivity.

Effect of hearing intervention on communicative function: A secondary analysis of the ACHIEVE randomized controlled trial.

Background: The Aging and Cognitive Health Evaluation in Elders (ACHIEVE) Study was designed to determine the effects of a best-practice hearing intervention on cognitive decline among community-dwelling older adults. Here, we conducted a secondary analysis of the ACHIEVE Study to investigate the effect of hearing intervention on self-reported communicative function.

Methods: The ACHIEVE Study is a parallel-group, unmasked, randomized controlled trial of adults aged 70-84 years with untreated mild-to-moderate hearing loss and without substantial cognitive impairment.

Pathophysiology and Treatment of Prediabetes and Type 2 Diabetes in Youth.

Youth-onset type 2 diabetes is a heterogeneous disease with increasing prevalence in relation to increased rates of obesity in children. It has genetic, epigenetic, social, and environmental determinants. Youth-onset type 2 diabetes is alarming given a rapidly progressive course compared with the course of adult-onset disease, early-onset vascular complications, and long-term exposure to hyperglycemia and associated complications.

Cost-effectiveness of vaccinating adults aged 60 years and older against respiratory syncytial virus.

Respiratory syncytial virus (RSV) causes substantial morbidity and mortality in older adults. In May 2023, two subunit RSV vaccines (Arexvy [GSK] and Abrysvo [Pfizer]) received approval from the U.S.

Jurisdiction-level costs of the initial phase of the COVID-19 vaccination program in the United States, December 20, 2020-May 31, 2021.

This study aimed to quantify U.S. jurisdiction-level costs related to the COVID-19 Vaccination Program by estimating the per-dose-administered cost during December 20, 2020-May 31, 2021, from a combined federal and local government perspective.

contribution of promoter vitamin D response elements.

CYP24A1 is a multifunctional, P450 mitochondrial 24-hydroxylase enzyme that is responsible for catabolism of the most active vitamin D hormone (calcitriol, 1,25(OH)D), its precursor (calcifediol, 25(OH)D), and numerous other vitamin D metabolites at the 23- and 24-carbon positions. In the kidney, is induced by 1,25(OH)D, induced by FGF23, and potently suppressed by PTH to tightly control the circulating blood levels of 1,25(OH)D. This gene is believed to be under the control of a pair of classic promoter proximal (PRO) vitamin D response elements (VDREs) that are aided by distal, downstream (DS) containing enhancers that we identified more recently.

Effect of Hearing Intervention Versus Health Education Control on Fatigue: A Secondary Analysis of the ACHIEVE Study.

Background: Fatigue is a common complaint among older adults with hearing loss. The impact of addressing hearing loss on fatigue symptoms has not been studied in a randomized controlled trial. In a secondary analysis of the Aging and Cognitive Health Evaluation in Elders (ACHIEVE) study, we investigated the effect of hearing intervention versus health education control on 3-year change in fatigue in community-dwelling older adults with hearing loss.

Generational Immigration Status Modifies the Association Between Psychosocial Distress and Substance Use Among Alternative High School Students.

Purpose: Alternative high schools (AHS) are designed to provide individualized education, more flexible scheduling, and smaller class sizes for students referred out of traditional high school. AHS students report higher levels of substance use (SU) and face disproportionately higher levels of trauma and toxic stress than their traditional high school peers. We sought to examine whether generational immigration (GenIm) status modifies the association of mental health and SU among AHS students using a longitudinal study of 1,060 Southern California AHS students.

Traumatic brain injury and cognitive change over 30 years among community-dwelling older adults.

Introduction: There is limited evidence regarding the rate of long-term cognitive decline after traumatic brain injury (TBI) among older adults.

Methods: In this prospective cohort study, time-varying TBI was defined by self-report and International Classification of Disease diagnostic codes. Cognitive testing was performed at five visits over 30 years and scores were combined into a global cognition factor score.

Healthcare resource utilization and economic burden of multiple sclerosis in Chinese patients: results from a real-world survey.

Multiple sclerosis (MS) is uncommon in China and the standard of care is underdeveloped, with limited utilization of disease-modifying treatment (DMT). An understanding of real-world disease burden (including direct medical, non-medical, and indirect costs, such as loss of productivity), is currently lacking in this population. To investigate the overall burden of managing patients with MS in China, a cross-sectional survey of physicians and their consulting patients with MS was conducted in 2021.

Age of Diabetes Diagnosis and Lifetime Risk of Dementia: The Atherosclerosis Risk in Communities (ARIC) Study.

Objective: The impact of age of diabetes diagnosis on dementia risk across the life course is poorly characterized. We estimated the lifetime risk of dementia by age of diabetes diagnosis.

Research Design And Methods: We included 13,087 participants from the Atherosclerosis Risk in Communities Study who were free from dementia at age 60 years.

Spatial detection and consequences of nonrenal calcitriol production as assessed by targeted mass spectrometry imaging.

The immune benefits of vitamin D3 supplementation beyond calcium and phosphate maintenance are highly clinically debated. Kidney expression of CYP27B1 is the source of endocrine, circulating 1,25(OH)2D3 (active form of vitamin D) that maintains serum calcium and phosphate. 1,25(OH)2D3 may also be made by the CYP27B1 enzyme in nonrenal cells, like immune cells, in a process driven by cellular availability of 25(OH)D3 and inflammation.
