Abstract Patients with H3K27M-mutant diffuse midline glioma (DMG) have no proven effective therapies. ONC201 has recently demonstrated efficacy in these patients, but the mechanism behind this finding remains unknown. We assessed clinical outcomes, tumor sequencing, and tissue/cerebrospinal fluid (CSF) correlate samples from patients treated in two completed multisite clinical studies. Patients treated with ONC201 following initial radiation but prior to recurrence demonstrated a median overall survival of 21.7 months, whereas those treated after recurrence had a median overall survival of 9.3 months. Radiographic response was associated with increased expression of key tricarboxylic acid cycle–related genes in baseline tumor sequencing. ONC201 treatment increased 2-hydroxyglutarate levels in cultured H3K27M-DMG cells and patient CSF samples. This corresponded with increases in repressive H3K27me3 in vitro and in human tumors accompanied by epigenetic downregulation of cell cycle regulation and neuroglial differentiation genes. Overall, ONC201 demonstrates efficacy in H3K27M-DMG by disrupting integrated metabolic and epigenetic pathways and reversing pathognomonic H3K27me3 reduction. Significance: The clinical, radiographic, and molecular analyses included in this study demonstrate the efficacy of ONC201 in H3K27M-mutant DMG and support ONC201 as the first monotherapy to improve outcomes in H3K27M-mutant DMG beyond radiation. Mechanistically, ONC201 disrupts integrated metabolic and epigenetic pathways and reverses pathognomonic H3K27me3 reduction. This article is featured in Selected Articles from This Issue, p. 2293

Background and Aims: Fatty liver disease is a major public health threat due to its very high prevalence and related morbidity and mortality. Focused and dedicated interventions are urgently needed to target disease prevention, treatment, and care. Approach and Results: We developed an aligned, prioritized action agenda for the global fatty liver disease community of practice. Following a Delphi methodology over 2 rounds, a large panel (R1 n = 344, R2 n = 288) reviewed the action priorities using Qualtrics XM, indicating agreement using a 4-point Likert-scale and providing written feedback. Priorities were revised between rounds, and in R2, panelists also ranked the priorities within 6 domains: epidemiology, treatment and care, models of care, education and awareness, patient and community perspectives, and leadership and public health policy. The consensus fatty liver disease action agenda encompasses 29 priorities. In R2, the mean percentage of “agree” responses was 82.4%, with all individual priorities having at least a super-majority of agreement (> 66.7% “agree”). The highest-ranked action priorities included collaboration between liver specialists and primary care doctors on early diagnosis, action to address the needs of people living with multiple morbidities, and the incorporation of fatty liver disease into relevant non-communicable disease strategies and guidance. Conclusions: This consensus-driven multidisciplinary fatty liver disease action agenda developed by care providers, clinical researchers, and public health and policy experts provides a path to reduce the prevalence of fatty liver disease and improve health outcomes. To implement this agenda, concerted efforts will be needed at the global, regional, and national levels.

Abstract Purpose: Germline pathogenic variants in CHEK2 confer moderately elevated breast cancer risk (odds ratio, OR ∼ 2.5), qualifying carriers for enhanced breast cancer screening. Besides pathogenic variants, dozens of missense CHEK2 variants of uncertain significance (VUS) have been identified, hampering the clinical utility of germline genetic testing (GGT). Experimental Design: We collected 460 CHEK2 missense VUS identified by the ENIGMA consortium in 15 countries. Their functional characterization was performed using CHEK2-complementation assays quantifying KAP1 phosphorylation and CHK2 autophosphorylation in human RPE1–CHEK2-knockout cells. Concordant results in both functional assays were used to categorize CHEK2 VUS from 12 ENIGMA case–control datasets, including 73,048 female patients with breast cancer and 88,658 ethnicity-matched controls. Results: A total of 430/460 VUS were successfully analyzed, of which 340 (79.1%) were concordant in both functional assays and categorized as functionally impaired (N = 102), functionally intermediate (N = 12), or functionally wild-type (WT)–like (N = 226). We then examined their association with breast cancer risk in the case–control analysis. The OR and 95% CI (confidence intervals) for carriers of functionally impaired, intermediate, and WT-like variants were 2.83 (95% CI, 2.35–3.41), 1.57 (95% CI, 1.41–1.75), and 1.19 (95% CI, 1.08–1.31), respectively. The meta-analysis of population-specific datasets showed similar results. Conclusions: We determined the functional consequences for the majority of CHEK2 missense VUS found in patients with breast cancer (3,660/4,436; 82.5%). Carriers of functionally impaired missense variants accounted for 0.5% of patients with breast cancer and were associated with a moderate risk similar to that of truncating CHEK2 variants. In contrast, 2.2% of all patients with breast cancer carried functionally wild-type/intermediate missense variants with no clinically relevant breast cancer risk in heterozygous carriers.

AbstractIntroductionThe potential benefits of electroconvulsive therapy (ECT) in chronic pain and several theories for its mechanism have been reported in the past, but mixed findings have also been reported. In the current systematic review and case series, our primary aim was to assess whether pain and functional outcomes are improved after ECT in patients with chronic pain. Secondary objectives included examining whether psychiatric improvement, specific pain diagnoses, and demographic or medical characteristics were associated with differences in pain treatment response.MethodsWe performed a retrospective chart review to identify patients with chronic pain diagnoses for more than 3 months prior to the initiation of ECT and a systematic literature search on electronic databases for studies on chronic pain outcomes after ECT.ResultsEleven patients with various chronic pain diagnoses and comorbid psychiatric conditions were identified in the case series. Six patients reported improvement in pain while 10 patients reported improvement in mood following ECT. Systematic review identified 22 articles reporting a total of 109 cases. Eighty‐five (78%) of cases reported reduction in pain while 96.3% of the patients with a comorbid psychiatric diagnosis reported improvement in mood symptoms post‐ECT. While there was an association between improvement in mood and pain in studies with numeric ratings in both outcomes (r = 0.61; p < 0.001), some patients reported pain improvement without improvement in mood in both the case series and the pooled analysis of cases in the review. Certain pain diagnoses such as CRPS, phantom limb pain, neuropathic pain, and low back pain have consistently reported benefits and should be further studied in future studies with matched case controls.ConclusionECT may be offered to patients with certain pain conditions who have not responded sufficiently to conventional therapies, particularly when comorbid mood symptoms are present. Improved documentation practices on the outcomes in chronic pain patients receiving ECT will help generate more studies that are needed on this topic.

OBJECTIVES To describe the quality of pediatric resuscitative care in general emergency departments (GEDs) and to determine hospital-level factors associated with higher quality. METHODS Prospective observational study of resuscitative care provided to 3 in situ simulated patients (infant seizure, infant sepsis, and child cardiac arrest) by interprofessional GED teams. A composite quality score (CQS) was measured and the association of this score with modifiable and nonmodifiable hospital-level factors was explored. RESULTS A median CQS of 62.8 of 100 (interquartile range 50.5–71.1) was noted for 287 resuscitation teams from 175 emergency departments. In the unadjusted analyses, a higher score was associated with the modifiable factor of an affiliation with a pediatric academic medical center (PAMC) and the nonmodifiable factors of higher pediatric volume and location in the Northeast and Midwest. In the adjusted analyses, a higher CQS was associated with modifiable factors of an affiliation with a PAMC and the designation of both a nurse and physician pediatric emergency care coordinator, and nonmodifiable factors of higher pediatric volume and location in the Northeast and Midwest. A weak correlation was noted between quality and pediatric readiness scores. CONCLUSIONS A low quality of pediatric resuscitative care, measured using simulation, was noted across a cohort of GEDs. Hospital factors associated with higher quality included: an affiliation with a PAMC, designation of a pediatric emergency care coordinator, higher pediatric volume, and geographic location. A weak correlation was noted between quality and pediatric readiness scores.

Objective Myelin oligodendrocyte glycoprotein antibody‐associated disease (MOGAD) can be monophasic or relapsing, with early relapse being a feature. However, the relevance of early relapse on longer‐term relapse risk is unknown. Here, we investigate whether early relapses increase longer‐term relapse risk in patients with MOGAD. Methods A retrospective analysis of 289 adult‐ and pediatric‐onset patients with MOGAD followed for at least 2 years in 6 specialized referral centers. “Early relapses” were defined as attacks within the first 12 months from onset, with “very early relapses” defined within 30 to 90 days from onset and “delayed early relapses” defined within 90 to 365 days. “Long‐term relapses” were defined as relapses beyond 12 months. Cox regression modeling and Kaplan–Meier survival analysis were used to estimate the long‐term relapse risk and rate. Results Sixty‐seven patients (23.2%) had early relapses with a median number of 1 event. Univariate analysis revealed an elevated risk for long‐term relapses if any “early relapses” were present (hazard ratio [HR] = 2.11, p < 0.001), whether occurring during the first 3 months (HR = 2.70, p < 0.001) or the remaining 9 months (HR = 1.88, p = 0.001), with similar results yielded in the multivariate analysis. In children with onset below aged 12 years, only delayed early relapses were associated with an increased risk of long‐term relapses (HR = 2.64, p = 0.026). Interpretation The presence of very early relapses and delayed early relapses within 12 months of onset in patients with MOGAD increases the risk of long‐term relapsing disease, whereas a relapse within 90 days appears not to indicate a chronic inflammatory process in young pediatric‐onset disease.

AbstractCeliac disease is a global disease requiring genetic susceptibility and gluten exposure to trigger immune‐mediated enteropathy. The effect of the degree of gluten‐containing grain availability on celiac disease prevalence is unknown. Our objective was to compare country‐based gluten availability to celiac prevalence using a systematic literature review. We searched MEDLINE, Embase, Cochrane, and Scopus until May 2021. We included population‐based serum screening with confirmatory testing (second serological study or small intestine biopsy) and excluded specific, high‐risk, or referral populations. We determined country‐specific gluten availability using the United Nations food balance for wheat, barley, and rye. Human leukocyte antigen (HLA) frequencies were obtained from allelefrequencies.net. The primary outcome was association between gluten‐containing grain availability and celiac disease prevalence. Generalized linear mixed models method with Poisson's link was used for analysis. We identified 5641 articles and included 120 studies on 427 146 subjects from 41 countries. Celiac disease prevalence was 0–3.1%, median 0.75% (interquartile range 0.35, 1.22). Median wheat supply was 246 g/capita/day (interquartile range 214.8, 360.7). The risk ratio (RR) for wheat availability on celiac disease was 1.002 (95% confidence interval [CI]: 1.0001, 1.004, P = 0.036). A protective association was seen with barley, RR 0.973 (95% CI: 0.956, 0.99, P = 0.003), and rye, RR 0.989 (95% CI: 0.982, 0.997, P = 0.006). The RR for gross domestic product on celiac disease prevalence was 1.009 (95% CI: 1.005, 1.014, P < 0.001). The RR for HLA‐DQ2 was 0.982 (95% CI: 0.979, 0.986, P < 0.001), and that for HLA‐DQ8 was 0.957 (95% CI: 0.950, 0.964, P < 0.001). In this geo‐epidemiologic study, gluten‐containing grain availability showed mixed associations with celiac disease prevalence.
