Support groups are a promising resource, but eating disorder (ED) support group research is scarce. This study aimed to examine associations between support group utilization, psychosocial health, and ED symptoms to guide future research on this resource. Participants ( = 494) were sampled from virtual, clinician-moderated ED support groups.

OHBSS scales assess social support for toothbrushing, flossing, and dental care utilization, which are targets for interpersonal-level interventions to promote oral health among Hispanic/Latino adults. The focus was on Mexican-origin adults, who comprise the largest United States Hispanic/Latino subgroup and experience a high oral disease burden.

The pandemic forced adjustments in BC management and may have also impacted BC presentation characteristics due to social behavior changes. The aim of this study was to describe BC presentations before and during the COVID-19 pandemic at a single facility in SA.

This systematic review sought to synthesize the literature on SM use among individuals pre- and post-MBS. Objectives were to: 1) explore the patterns of SM use in this population, 2) identify the benefits and risks of MBS-focused SM use, and 3) inform clinicians and patients about strategies to more effectively engage with MBS-focused SM.

Cognitive inflexibility (i.e.

Participants (n = 200 white, n = 199 Black) completed a pre-exposure measure of ethnic identity and pre-post measure of body satisfaction (where lower scores indicate dissatisfaction) after randomization to thin or curvy body ideal conditions. Black women endorsed higher pre-exposure ethnic identity than white women but did not differ in level of body dissatisfaction.

This process evaluation study seeks to assess the role of CHWs in social risk screening, referral, and follow-up through process mapping to identify barriers to the process for future quality improvement efforts.
Methods: Researchers at the Arizona Prevention Research Center (AzPRC) engaged with two Federally Qualified Health Centers (FQHCs) in two of Arizona's major urban areas to evaluate their internal processes for social risk screening and intervention.

Emerging research indicates that even low-dose radiation once believed to be safe, may have harmful effects. This perception has spurred a growing interest in investigating the potential risks associated with low-dose radiation exposure across various scenarios.

Endothelial dysfunction in advanced PAH is associated with proliferation, apoptosis resistance, and endothelial to mesenchymal transition (EndoMT) due to aberrant signaling. DLL4, a cell membrane associated NOTCH ligand, plays a pivotal role maintaining vascular integrity.

No studies have examined the effect of treatment on within-day timing of loss of control eating severity. We examined whether time of day differentially predicted loss of control eating severity at baseline (i.

In cats, canine TSH chemiluminescent immunoassays (CLIA) assays are commonly used to measure TSH, but these TSH-CLIAs cannot measure low TSH concentrations (< 0.03 ng/mL) and therefore cannot distinguish between low-normal concentrations and truly low TSH concentrations (characteristic of hyperthyroidism).

At baseline, participants completed diagnostic interviews, height/weight measurements, and measures of set-shifting (the Intradimensional/Extradimensional shift task) and reversal learning (a probabilistic reversal learning task). At 3- and 6-month follow-up, participants with eating disorders completed assessments of weight and eating disorder symptoms.

In this review, we discuss the major research issues that need to be addressed to expedite this transformation along with the salient challenges involved. We especially focus on Bayesian signal processing and machine learning schemes that are uncertainty aware and physics informed for knowledge-driven learning, robust optimization, and efficient objective-driven experimental design.

However, the enormous search space containing the candidates and the substantial computational cost of high-fidelity property prediction models make screening practically challenging. In this work, we propose a general framework for constructing and optimizing a high-throughput virtual screening (HTVS) pipeline that consists of multi-fidelity models.

Little is known about factors that contribute to the persistence of these behaviors. This study explored whether habitual control over binge/purge (B/P) spectrum behaviors contributes to symptom persistence and whether negative reinforcement via reductions in negative affect is less influential in maintaining B/P behaviors that are under habitual control and are persistent.

However, recent empirical work outside of the field of EDs challenges this categorical conceptualization of strategies, demonstrating that adaptiveness is determined by the ability to flexibly implement and adjust strategies based on contextual demands (i.e.

Gram-negative bacteria are common pathogens that can activate host immune responses through their outer membrane component, LPS. Macrophage activation by LPS induces cell signals that promote hypoxic metabolism, phagocytosis, Ag presentation, and inflammation.

This relationship may be particularly salient among youth with overweight/obesity, given that social marginalization of larger bodies has been associated with elevated SWC and barriers to PA. This pilot study explores reciprocal relationships between momentary SWC and accelerometer-assessed PA behavior.
