ABSTRACT

Background: Janus kinase inhibitor (JAKi) therapy has revolutionized the treatment landscape for alopecia areata (AA); however, access may be limited by a lack of insurance coverage and high out-of-pocket costs. Objective: We aimed to evaluate real-world patient experiences regarding access to JAKi therapy. Methods: We conducted an online patient-centered survey using the National Alopecia Areata Foundation listserv. Results: In total 784 individuals initiated our survey, and 600 completed it in full (76.5%). While more non-White patients considered obtaining JAKi therapy, more White patients reported the use of this medication class. In total, 74.2% lacked insurance coverage or had partial coverage for JAKi, and 52% expressed dissatisfaction with available coverage. However, 52.9% reported delays in starting medication due to insurance approval processes, contributing to worsened AA and related stress. In total, 35% of patients did not try to obtain JAKi therapy due to concerns about costs, and 18.2% discontinued therapy due to financial barriers. Also, 19.8% of patients reported utilizing financial savings to pay for medication, and 55.2% reported using a copay assistance card. Further, 12.2% reported forgoing other necessities to pay for AA expenses. Limitations: Our results are limited by the subjective nature of survey studies. The recency of FDA approval for JAKi therapy may also influence patients' perceptions of access to care. Conclusion: Patients with AA face significant barriers when trying to obtain JAKi therapy, and existing racial inequities may be exacerbated by these barriers. Further advocacy work is needed to improve access to care.

ABSTRACT

Medical students must be adept at critical thinking to successfully meet the learning objectives of their preclinical coursework. To encourage student success on assessments, the course director of a first-year medical physiology course emphasized the use of learning objectives that were explicitly aligned with formative assessments in class. The course director introduced the physiology discipline, learning objectives, and evidence-based methods of studying to students on the first day of class. Thereafter, class sessions started with a review of the learning objectives for that session and included active learning opportunities such as retrieval practice. The instructor provided short answer formative assessments aligned with the learning objectives, intended to help the students apply and integrate the concepts. Midsemester, students received a link to an online survey with questions on studying habits, class attendance, and student engagement. After finals, students were invited to participate in focus groups about their class experience. A qualitative researcher moderated focus groups, recorded responses, and analyzed the narrative data. Of 175 students, 95 submitted anonymous online surveys. Student engagement was significantly correlated with in-person class attendance (r = 0.26, T = 2.5, P = 0.01) and the completion of open-ended formative assessments (r = 0.33, T = 3.3, P = 0.001). Focus groups were held via videoconference. From the class, 14 students participated in 4 focus groups; focus group participants were mostly women (11 of 14) and mostly in-class attendees (13 of 14). The students in this sample valued critical thinking but misunderstood expectations on exams and few students used learning objectives to study.NEW & NOTEWORTHY We introduced formative assessments and study techniques to first-year medical students in a physiology course. Mastery of learning objectives was emphasized as the key to success. We asked how they studied physiology through an anonymous online survey and focus group interviews. The students enjoyed physiology but had difficulty with exam expectations. Helping students use learning objectives to guide their study may lead to improved exam scores. It may also help administrators meet their curriculum goals.

ABSTRACT

BACKGROUND: Allostatic load (AL) is a biological measure of cumulative exposure to socioenvironmental stressors (e.g., poverty). This study aims to examine the association between allostatic load (AL) and postoperative complications (POC) among patients with breast cancer. METHODS: Assigned females at birth ages 18 + with stage I-III breast cancer who received surgical management between 01/01/2012-12/31/2020 were identified in the Ohio State Cancer registry. The composite AL measure included biomarkers from the cardiovascular, metabolic, immune, and renal systems. High AL was defined as composite scores greater than the cohort's median (2.0). POC within 30 days of surgery were examined. Univariable and multivariable regression analysis examined the association between AL and POC. RESULTS: Among 4,459 patients, 8.2% had POC. A higher percentage of patients with POC were unpartnered (POC 44.7% vs no POC 35.5%), government-insured (POC 48.2% vs no POC 38.3%) and had multiple comorbidities (POC 32% vs no POC 20%). Patients who developed POC were more likely to have undergone sentinel lymph node biopsy followed by axillary lymph node dissection (POC 51.2% vs no POC 44.6%). High AL was associated with 29% higher odds of POC (aOR 1.29, 95% CI 1.01-1.63). A one-point increase in AL was associated with 8% higher odds of POC (aOR 1.08, 95% CI 1.02-1.16) and a quartile increase in AL was associated with 13% increased odds of POC (aOR 1.13, 95% CI 1.01-1.26). CONCLUSION: Among patients undergoing breast cancer surgery, increased exposure to adverse socioenvironmental stressors, operationalized as AL, was associated with higher odds of postoperative complications.

ABSTRACT

AIMS: Patients with chronic kidney disease (CKD) or heart failure (HF) are disproportionally affected by frailty, an independent predictor of morbidity. The prevalence of frailty and its impact on quality of life (QoL) in a unique population of patients with both CKD and HF (CKD-HF) is unclear. The aim of this study was to investigate the association between frailty and QoL in patients with CKD-HF. METHODS AND RESULTS: Patients were identified from a tertiary care cardiorenal clinic. Eligible patients had CKD-HF with a stable estimated glomerular filtration rate of <60 mL/min/1.732. Data were collected from each participant at one point in time using surveys delivered by study personnel between 14 July 2022 and 31 March 2023. Frailty was defined as Modified Frailty Phenotype (MFP) score ≥3. The Medical Outcomes Study 36-item Short Form Health Survey (SF-36) was used to assess QoL. Demographic data were retrospectively collected from electronic patient records. Demographics and QoL were compared between frail and non-frail cohorts using Pearson's R and Student's t-test (two-tailed, alpha-priori = 0.05). One hundred five participants consented, and 103 completed the questionnaires in full. Amongst the 103 participants, 49.5% (n = 51) were frail. Frailty was related to sex (P = 0.021) and medication count (P = 0.007), however not to other clinical measures, including estimated glomerular filtration rate (P = 0.437) and ejection fraction (P = 0.911). Frail patients reported poorer QoL across physical functioning (P < 0.001), general health (P < 0.001), bodily pain (P = 0.004), social functioning (P < 0.001), and energy levels (P < 0.001), however not emotional wellbeing (P = 0.058); 51.5% cited 'better quality of life' as their healthcare priority, over longer survival (23.3%) or avoiding hospital admissions (22.3%). This was consistent across frail and non-frail groups. CONCLUSIONS: A large proportion of CKD-HF patients are frail, regardless of disease severity, and more susceptible to significantly poorer QoL across physical and social domains. Improving QoL is the priority of patients across both frail and non-frail cohorts, further emphasizing the need for prompt recognition of frailty as well as possible intervention and prevention.

ABSTRACT

Efficient delivery of therapeutics to the central nervous system (CNS) remains a major challenge for the treatment of neurological diseases. Huntington disease (HD) is a dominantly inherited neurodegenerative disorder caused by a CAG trinucleotide expansion mutation in the HTT gene which codes for a toxic mutant huntingtin (mHTT) protein. Pharmacological reduction of mHTT in the CNS using antisense oligonucleotides (ASO) ameliorates HD-like phenotypes in rodent models of HD, with such therapies being investigated in clinical trials for HD. In this study, we report the optimization of apolipoprotein A-I nanodisks (apoA-I NDs) as vehicles for delivery of a HTT-targeted ASO (HTT ASO) to the brain and peripheral organs for HD. We demonstrate that apoA-I wild type (WT) and the apoA-I K133C mutant incubated with a synthetic lipid, 1,2-dimyristoyl-sn-glycero-3-phosphocholine, can self-assemble into monodisperse discoidal particles with diameters <20 nm that transmigrate across an in vitro blood-brain barrier model of HD. We demonstrate that apoA-I NDs are well tolerated in vivo, and that apoA-I K133C NDs show enhanced distribution to the CNS and peripheral organs compared to apoA-I WT NDs following systemic administration. ApoA-I K133C conjugated with HTT ASO forms NDs (HTT ASO NDs) that induce significant mHTT lowering in the liver, skeletal muscle and heart as well as in the brain when delivered intravenously in the BACHD mouse model of HD. Furthermore, HTT ASO NDs increase the magnitude of mHTT lowering in the striatum and cortex compared to HTT ASO alone following intracerebroventricular administration. These findings demonstrate the potential utility of apoA-I NDs as biocompatible vehicles for enhancing delivery of mutant HTT lowering ASOs to the CNS and peripheral organs for HD.

ABSTRACT

OBJECTIVE: Novel treatments for adults with anorexia nervosa (AN) are sorely needed. Although psychological interventions have been developed for AN, none have been identified as superior to one another or nonspecific treatments. Common comorbidities (e.g., mood and anxiety disorders) are rarely targeted in AN treatments, possibly impairing long-term clinical improvement. AN is associated with reward processing dysfunctions paralleling those identified in affective disorders; however, few treatments directly target these processes. METHOD: We adapted Positive Affect Treatment, a neuroscience-informed behavioral treatment developed for affective disorders, to the treatment of AN (PAT-AN). Adults with AN (N = 20) were randomized to 20 weeks of PAT-AN or waitlist to investigate the feasibility, acceptability, preliminary efficacy, and target engagement (on reward mechanisms) of PAT-AN. RESULTS: PAT-AN demonstrated strong retention (100%) and acceptability ratings (M = 5.67-5.95 on a 7-point scale). BMI (p = .006) and eating disorder symptoms (p < .001) improved over PAT-AN sessions. The PAT-AN group showed medium to large pre-to-post-treatment improvements in BMI, eating disorder symptoms and impairment, depressive and anxiety symptoms, and some reward indices (ds = .56-.87); changes were largely sustained at 3-month follow-up. Waitlist showed negligible changes (ds < .20) on nearly all measures. DISCUSSION: PAT-AN holds promise as an innovative treatment with capability to simultaneously improve eating disorder symptoms, affective symptoms, and underlying reward mechanisms. Findings should be interpreted cautiously due to small sample size and permitted concurrent enrollment in other treatments. Future, larger-scale research is warranted to establish the efficacy of PAT-AN. PUBLIC SIGNIFICANCE: This study provided a preliminary evaluation of Positive Affect Treatment for anorexia nervosa (PAT-AN), a novel, neuroscience-informed treatment aimed at increasing rewarding life experiences outside of one's eating disorder. Initial results suggest that PAT-AN is considered acceptable and may alleviate eating disorder, depressive, and anxiety symptoms. Therefore, this study presents promising data on a treatment that may hold potential for improving the lives of individuals with this disorder.

ABSTRACT

Diagnosing heart failure is often difficult due to the non-specific nature of symptoms, which can be caused by a range of medical conditions. Natriuretic peptides (NPs) have been recognized as important biomarkers for diagnosing heart failure. This document from the Heart Failure Association examines the practical uses of N-terminal pro-B-type natriuretic peptide (NT-proBNP) in various clinical scenarios. The concentrations of NT-proBNP vary according to the patient profile and the clinical scenario, therefore values should be interpreted with caution to ensure appropriate diagnosis. Validated cut-points are provided to rule in or rule out acute heart failure in the emergency department and to diagnose de novo heart failure in the outpatient setting. We also coin the concept of 'heart stress' when NT-proBNP levels are elevated in an asymptomatic patient with risk factors for heart failure (i.e. diabetes, hypertension, coronary artery disease), underlying the development of cardiac dysfunction and further increased risk. We propose a simple acronym for healthcare professionals and patients, FIND-HF, which serves as a prompt to consider heart failure: Fatigue, Increased water accumulation, Natriuretic peptide testing, and Dyspnoea. Use of this acronym would enable the early diagnosis of heart failure. Overall, understanding and utilizing NT-proBNP levels will lead to earlier and more accurate diagnoses of heart failure ultimately improving patient outcomes and reducing healthcare costs.

ABSTRACT

PURPOSE: Fatigue is a major symptom in patients with stroke. Because fatigue is an overarching multidimensional phenomenon, it is important to understand how the characteristics of fatigue change over time. The purpose of this study was to explore how fatigue characteristics change over time in patients with stroke. DESIGN: This study used a mixed-method observational design. METHODS: This study is a secondary analysis of data from a previous study, the results of which indicated fatigue to be a prominent symptom. Participants in that study were patients with stroke who met eligibility criteria and provided informed consent. This secondary analysis used data from numeric rating scale scores for fatigue, Functional Assessment of Chronic Illness Therapy-Fatigue Scale scores, fatigue descriptors, and participant comments about fatigue gleaned from transcribed interviews. RESULTS: Twenty-two patients participated in the study. Thirteen characteristics of fatigue were evaluated. Seven characteristics showed significant improvement ( p < .05) from admission to 1 month follow-up, and six characteristics did not change significantly. CONCLUSIONS: Fatigue experiences vary over time and have both physical and mental aspects to them. CLINICAL RELEVANCE TO REHABILITATION NURSING: Nurses may consider providing a quiet environment for physical rest, which may allow the brain to not be distracted by multiple stimuli.

ABSTRACT

AIMS: When relying on clinical assessment alone, an estimated 22% of acute heart failure (AHF) patients are missed, so clinical guidelines recommend the use of N-terminal pro-B-type natriuretic peptide (NT-proBNP) for AHF diagnosis. Since publication of these guidelines, there has been poor uptake of NT-proBNP testing in part due to concerns over excessive false positive referrals resulting from the low specificity of a single 'rule-out' threshold of <300 pg/mL. Low specificity can be mitigated by the addition of age-specific 'rule-in' NT-proBNP thresholds. METHODS AND RESULTS: A theoretical hybrid decision tree/semi-Markov model was developed, combining global trial and audit data to evaluate the cost-effectiveness of NT-proBNP testing using age-specific rule-in/rule-out (RI/RO) thresholds, compared with NT-proBNP RO only and with clinical decision alone (CDA). Cost-effectiveness was measured as the incremental cost per quality-adjusted life year (QALY) gained and incremental net health benefit. In the base case, using UK-specific inputs, NT-proBNP RI/RO was associated with both greater QALYs and lower costs than CDA. At a willingness-to-pay threshold of £20 000/QALY, NT-proBNP RO was also cost-effective compared with CDA [incremental cost-effectiveness ratio (ICER) of £8322/QALY], but not cost-effective vs. RI/RO (ICER of £64 518/QALY). Overall, NT-proBNP RI/RO was the most cost-effective strategy. Sensitivity and scenario analyses were undertaken; the conclusions were not impacted by plausible variations in parameters, and similar conclusions were obtained for the Netherlands and Spain. CONCLUSIONS: An NT-proBNP strategy that combines an RO threshold with age-specific RI thresholds provides a cost-effective alternative to the currently recommended NT-proBNP RO only strategy, achieving greater diagnostic specificity with minimal reduction in sensitivity and thus reducing unnecessary echocardiograms and hospital admissions.

ABSTRACT

OBJECTIVE: Precision medicine (i.e., individually tailored treatments) represents an optimal goal for treating complex psychiatric disorders, including eating disorders. Within the eating disorders field, most treatment development efforts have been limited in their ability to identify individual-level models of eating disorder psychopathology and to develop and apply an individually tailored treatment for a given individual's personalized model of psychopathology. In addition, research is still needed to identify causal relationships within a given individual's model of eating disorder psychopathology. Addressing this limitation of the current state of precision medicine-related research in the field will allow us to progress toward advancing research and practice for eating disorders treatment. METHOD: We present a novel set of analytic tools, causal discovery analysis (CDA) methods, which can facilitate increasingly fine-grained, person-specific models of causal relations among cognitive, behavioral, and affective symptoms. RESULTS: CDA can advance the identification of an individual's causal model that maintains that individuals' eating disorder psychopathology. DISCUSSION: In the current article, we (1) introduce CDA methods as a set of promising analytic tools for developing precision medicine methods for eating disorders including the potential strengths and weaknesses of CDA, (2) provide recommendations for future studies utilizing this approach, and (3) outline the potential clinical implications of using CDA to generate personalized models of eating disorder psychopathology. PUBLIC SIGNIFICANCE STATEMENT: CDA provides a novel statistical approach for identifying causal relationships among variables of interest for a given individual. Person-specific causal models may offer a promising approach to individualized treatment planning and inform future personalized treatment development efforts for eating disorders.

ABSTRACT

Lowering mutant huntingtin (mHTT) in the central nervous system (CNS) using antisense oligonucleotides (ASOs) is a promising approach currently being evaluated in clinical trials for Huntington disease (HD). However, the therapeutic potential of ASOs in HD patients is limited by their inability to cross the blood-brain barrier (BBB). In non-human primates, intrathecal infusion of ASOs results in limited brain distribution, with higher ASO concentrations in superficial regions and lower concentrations in deeper regions, such as the basal ganglia. To address the need for improved delivery of ASOs to the brain, we are evaluating the therapeutic potential of apolipoprotein A-I nanodisks (apoA-I NDs) as novel delivery vehicles for mHTT-lowering ASOs to the CNS after intranasal administration. Here, we have demonstrated the ability of apoA-I nanodisks to bypass the BBB after intranasal delivery in the BACHD model of HD. Following intranasal administration of apoA-I NDs, apoA-I protein levels were elevated along the rostral-caudal brain axis, with highest levels in the most rostral brain regions including the olfactory bulb and frontal cortex. Double-label immunohistochemistry indicates that both the apoA-I and ASO deposit in neurons. Most importantly, a single intranasal dose of apoA-I ASO-NDs significantly reduces mHTT levels in the brain regions most affected in HD, namely the cortex and striatum. This approach represents a novel non-invasive means for improving delivery and brain distribution of oligonucleotide therapies and enhancing likelihood of efficacy. Improved ASO delivery to the brain has widespread application for treatment of many other CNS disorders.

ABSTRACT

Clinical Physiology 1 and 2 are flipped classes in which students watch prerecorded videos before class. During the 3-h class, students take practice assessments, work in groups on critical thinking exercises, work through case studies, and engage in drawing exercises. Due to the COVID pandemic, these courses were transitioned from in-person classes to online classes. Despite the university's return-to-class policy, some students were reluctant to return to in-person classes; therefore during the 2021-2022 academic year, Clinical Physiology 1 and 2 were offered as flipped, hybrid courses. In a hybrid format, students either attended the synchronous class in person or online. Here we evaluate the learning outcomes and the perceptions of the learning experience for students who attended Clinical Physiology 1 and 2 either online (2020-2021) or in a hybrid format (2021-2022). In addition to exam scores, in-class surveys and end of course evaluations were compiled to describe the student experience in the flipped hybrid setting. Retrospective linear mixed-model regression analysis of exam scores revealed that a hybrid modality (2021-2022) was associated with lower exam scores when controlling for sex, graduate/undergraduate status, delivery method, and the order in which the courses were taken (F test: F = 8.65, df1 = 2, df2 = 179.28, P = 0.0003). In addition, being a Black Indigenous Person of Color (BIPOC) student is associated with a lower exam score, controlling for the same previous factors (F test: F = 4.23, df1 = 1, df2 = 130.28, P = 0.04), albeit with lower confidence; the BIPOC representation in this sample is small (BIPOC: n = 144; total: n = 504). There is no significant interaction between the hybrid modality and race, meaning that BIPOC and White students are both negatively affected in a hybrid flipped course. Instructors should consider carefully about offering hybrid courses and build in extra student support.NEW & NOTEWORTHY The transition from online to in-person teaching has been as challenging as the original transition to remote teaching with the onset of the pandemic. Since not all students were ready to return to the classroom, students could choose to take this course in person or online. This arrangement provided flexibility and opportunities for innovative class activities for students but introduced tradeoffs in lower test scores from the hybrid modality than fully online or fully in-person modalities.

ABSTRACT

Social media use is rapidly expanding in terms of frequency, duration, and the diversity of platforms available. Given evidence for associations between social media use, body image disturbances, and disordered eating it is important to identify potentially harmful aspects of social media use that could serve as intervention targets. This study surveyed two demographically diverse undergraduate student cohorts in 2015 and 2022 to compare patterns in social media use, body image, and disordered eating behaviors between samples, including as a function of the COVID-19 pandemic, and to test the hypothesized moderating role of specific content consumed in the association between social media use and maladaptive outcomes. Participants in 2022 reported greater body image disturbances, more frequent vomiting and laxative use, and more time spent on a greater number of social media accounts, with significantly greater use of image-based platforms such as Snapchat, TikTok, and YouTube. Moderated regression analyses suggest that type of content consumed, but not the amount of time spent on social media or diversity of platforms utilized, is associated with body image disturbances and disordered eating behaviors after controlling for gender and body mass index. Specifically, exposure to weight loss content was associated with lower body appreciation, greater fears of negative appearance evaluation, and more frequent binge eating. Contrary to initial hypotheses, exposure to body positivity/neutrality content did not have protective effects. Findings suggest that interventions targeting negative consequences of social media use should focus on addressing content consumed, rather than time spent on social media platforms.

ABSTRACT

ABSTRACT: BACKGROUND: Alzheimer disease (AD) is a neurodegenerative disease with no cure. The number of individuals living with AD doubles every 5 years. The current clinical practice relies on clinical history, mental status tests, cerebrum imaging, and physical and neurological examinations; however, recent advances in the field of biomarkers have provided clues for the early detection of AD. High levels of tau and low levels of amyloid-ß (Aß) in cerebrospinal fluid are well-known biomarkers for AD. METHODS: A database search of PubMed, Ovid MEDLINE, and CINAHL was conducted to identify relevant articles published within the last 5 years. The search was limited to articles concerning adults 65 years or older and published in the English language. Twelve articles were included in the review. RESULTS: Risk factors of sleep disruption, depression, and motor function are implicated. Cerebrospinal fluid parameters for biomarkers of tau and Aß were universally lower among Blacks compared with Whites, raising concern that norm reference may not be accurate for all populations. Older adults are more at risk for AD. Results are inconclusive regarding whether depression is related to Aß and tau pathology. CONCLUSION: Nurses should screen for sleep architecture, depression, and motor function in their patients and educate them on good sleep hygiene. Sleep studies should be advocated for people with suspected sleep apnea to mitigate the risk factor related to abnormal Aß and tau pathology. Falls and decreased motor function require screening because they may be early indicators of abnormal biomarkers leading to AD.

ABSTRACT

Identification of somatic variants in cancer by high-throughput sequencing has become common clinical practice, largely because many of these variants may be predictive biomarkers for targeted therapies. However, there can be high sample quality control (QC) failure rates for some tests that prevent the return of results. Stem-loop inhibition mediated amplification (SLIMamp) is a patented technology that has been incorporated into commercially available cancer next-generation sequencing testing kits. The claimed advantage is that these kits can interrogate challenging formalin-fixed, paraffin-embedded tissue samples with low tumor purity, poor-quality DNA, and/or low-input DNA, resulting in a high sample QC pass rate. The study aimed to substantiate that claim using Pillar Biosciences oncoReveal Solid Tumor Panel. Forty-eight samples that had failed one or more preanalytical QC sample parameters for whole-exome sequencing from the Australian Translational Genomics Centre's ISO15189-accredited diagnostic genomics laboratory were acquired. XING Genomic Services performed an exploratory data analysis to characterize the samples and then tested the samples in their ISO15189-accredited laboratory. Clinical reports could be generated for 37 (77%) samples, of which 29 (60%) contained clinically actionable or significant variants that would not otherwise have been identified. Eleven samples were deemed unreportable, and the sequencing data were likely dominated by artifacts. A novel postsequencing QC metric was developed that can discriminate between clinically reportable and unreportable samples.

ABSTRACT

Normal urine residual volume (URV) in dogs has not previously been established by direct measurement. Twenty-two client-owned normal healthy dogs (8 female spayed, 12 male castrated, 2 male intact) without history of urinary abnormalities were included. Dogs were walked outside for 5 min to allow for natural voiding, immediately followed by urinary bladder ultrasound and urinary catheterization. The URV was recorded, and the ultrasound images were used to estimate URV for each dog. There was no significant difference between male and female URV; therefore, all data were pooled. With a 90% confidence interval, URV was 0-0.47 mL/kg with a mean URV of 0.21 mL/kg and a median value of 0.175 mL/kg. There was no significant difference between the measured URV and the ultrasound-determined URV. This case series supports previously established normal URV in the dog; however, a reference interval based on a larger population of dogs with further evaluation of body size/weight, sex, and neuter status is recommended to be established for use in clinical setting to differentiate normal urination from urinary retention in patients.

ABSTRACT

OBJECTIVE: There is increasing consensus that open science practices improve the transparency and quality of clinical science. However, several barriers impede the implementation of these practices at the individual, institutional, and field levels; understanding and addressing these barriers is critical to promoting targeted efforts in increasing effective uptake of open science. METHODS: Within this research forum, we drew from publicly available online information sources to identify initial characterizations of researchers engaged in several types of open science practices in the field of eating disorders. We use these observations to discuss potential barriers and recommendations for next steps in the promotion of these practices. RESULTS: Data from online open science repositories suggest that individuals using these publishing approaches with pre-prints and articles with eating-disorder-relevant content are predominantly non-male gender identifying, early to mid-career stage, and are more likely to be European-, United States-, or Canada-based. DISCUSSION: We outline recommendations for tangible ways that the eating disorder field can support broad, increased uptake of open science practices, including supporting initiatives to increase knowledge and correct misconceptions; and prioritizing the development and accessibility of open science resources. PUBLIC SIGNIFICANCE STATEMENT: The use of open science practices has the potential to increase the transparency and quality of clinical science. This Forum uses publicly sourced online data to characterize researchers engaged in open science practices in the field of eating disorders. These observations provide an important framework from which to discuss potential barriers to open science and recommendations for next steps in the promotion of these practices.

ABSTRACT

Internalizing mental disorders are highly comorbid with one another, and evidence suggests that etiological processes contributing to these disorders often overlap. This systematic umbrella review aimed to synthesize meta-analytic evidence from observational longitudinal studies to provide a comprehensive overview of potentially modifiable risk and protective factors across the depressive, anxiety, and eating disorder psychopathology domains. Six databases were searched from inception to August 2022. Only meta-analyses of longitudinal studies that accounted for baseline psychopathology (either via exclusion of baseline cases or statistical adjustment for baseline symptoms) were included. Methodological quality of meta-analyses was evaluated using the AMSTAR 2, and quality of evidence for each analysis was rated using GRADE. Study selection, quality assessment, and data extraction were conducted in duplicate by independent reviewers. The protocol for this review was registered with PROSPERO (CRD42020185575). Sixty-one meta-analyses were included, corresponding to 137 meta-analytic estimates for unique risk/protective factor-psychopathology relationships. Most potential risk/protective factors, however, were examined only in relation to depressive psychopathology. Concern over mistakes and self-esteem were the only risk and protective factors, respectively, identified as statistically significant across depressive, anxiety, and eating disorder psychopathology domains. Eight risk factors and four protective factors also emerged as having transdiagnostic relevance across depressive and anxiety domains. Results suggest intervention targets that may be valuable for preventing/treating the spectrum of internalizing psychopathology and reducing comorbidity. However, few factors were identified as transdiagnostically relevant across all three internalizing domains, highlighting the need for more research investigating similar sets of potential risk/protective factors across internalizing domains.
