Background:Research on the utilization and effectiveness of antitumor necrosis factor (TNF) biologics in children with very early onset inflammatory bowel disease (VEOIBD) is urgently needed. Here we describe anti‐TNF use and durability in a multicenter cohort.Methods:We performed a retrospective cohort study of patients diagnosed with VEOIBD (<6 years) between 2008 and 2013 at 25 North American centers. We performed chart abstraction at diagnosis and 1, 3, and 5 years after diagnosis. We examined the rate of initiation and durability of infliximab and adalimumab and evaluated associations between treatment durability and the following covariates with multivariate Cox proportional hazard regression: age at diagnosis, sex, disease duration, disease classification, and presence of combined immunomodulatory treatment versus monotherapy.Results:Of 294 children with VEOIBD, 120 initiated treatment with anti‐TNF therapy and 101 had follow‐up data recorded [50% Crohn disease (CD), 31% ulcerative colitis (UC), and 19% IBD unclassified (IBD‐U)]. The cumulative probability of anti‐TNF treatment was 15% at 1 year, 30% at 3 years, and 45% at 5 years from diagnosis; 56 (55%) were treated between 0 and 6 years old. Anti‐TNF durability was 90% at 1 year, 75% at 3 years, and 55% at 5 years. The most common reason for discontinuation of anti‐TNF were loss of response in 24 (57%) children. Children with UC/IBD‐U had lower durability than those with CD (hazard ratio [HR] 0.17; 95% confidence interval [CI], 0.06–0.51; P = 0.001).Conclusions:Utilization and durability of anti‐TNF in VEOIBD is relatively high and comparable with older children. Having Crohn disease (compared with UC/IBD‐U) is associated with greater durability.

Abstract Introduction In this longitudinal study, we aimed to examine if slowing gait speed preceded cognitive decline and correlated with brain amyloidosis. Methods The sample (n = 287) was derived from the Gothenburg H70 Birth Cohort Studies, with follow‐ups between 2000 and 2015. Gait speed was measured by indoor walk, and cognition using the Clinical Dementia Rating (CDR) score. All participants had CDR = 0 at baseline. Some participants had data on cerebrospinal fluid (CSF) amyloid beta (Aβ) 1‐42 concentrations at the 2009 examination. Results Gait speed for participants who worsened in CDR score during follow‐up was slower at most examinations. Baseline gait speed could significantly predict CDR change from baseline to follow‐up. Subjects with pathological CSF Aβ 1‐ 42 concentrations at the 2009 visit had lost more gait speed compared to previous examinations. Discussion Our results indicate that gait speed decline precedes cognitive decline, is linked to Alzheimer's pathology, and might be used for early detection of increased risk for dementia development.

Abstract Objective To describe and demonstrate use of pediatric data collected by the All of Us Research Program. Materials and Methods All of Us participant physical measurements and electronic health record (EHR) data were analyzed including investigation of trends in childhood obesity and correlation with adult body mass index (BMI). Results We identified 19 729 participants with legacy pediatric EHR data including diagnoses, prescriptions, visits, procedures, and measurements gathered since 1980. We found an increase in pediatric obesity diagnosis over time that correlates with BMI measurements recorded in participants’ adult EHRs and those physical measurements taken at enrollment in the research program. Discussion We highlight the availability of retrospective pediatric EHR data for nearly 20 000 All of Us participants. These data are relevant to current issues such as the rise in pediatric obesity. Conclusion All of Us contains a rich resource of retrospective pediatric EHR data to accelerate pediatric research studies.

There is no clear consensus regarding the optimal approach for secondary prophylaxis of gastric variceal bleeding (GVB) in patients with cirrhosis. We conducted a systematic review and network meta‐analysis (NMA) to compare the efficacy of available treatments. A comprehensive search of several databases from each database's inception to March 23, 2021, was conducted to identify relevant randomized controlled trials (RCTs). Outcomes of interest were rebleeding and mortality. Results were expressed as relative risk (RR) and 95% confidence interval (CI). We followed the Grading of Recommendations Assessment, Development, and Evaluation approach to rate the certainty of evidence. We included 9 RCTs with 647 patients who had histories of GVB and follow‐ups >6 weeks. A total of 9 interventions were included in the NMA. Balloon‐occluded retrograde transvenous obliteration (BRTO) was associated with a lower risk of rebleeding when compared with β‐blockers (RR, 0.04; 95% CI, 0.01‐0.26; low certainty), and endoscopic injection sclerotherapy (EIS)–cyanoacrylate (CYA) (RR, 0.18; 95% CI, 0.04‐0.77; low certainty). β‐blockers were associated with a higher risk of rebleeding compared with most interventions and with increased mortality compared with EIS‐CYA (RR, 4.12, 95% CI, 1.50‐11.36; low certainty), and EIS‐CYA + nonselective β‐blockers (RR, 5.61; 95% CI, 1.91‐16.43; low certainty). Analysis based on indirect comparisons suggests that BRTO may be the best intervention in preventing rebleeding, whereas β‐blocker monotherapy is likely the worst in preventing rebleeding and mortality. Head‐to‐head RCTs are needed to validate these results.

Background: The modifying effect of sex on the relation between marital status and dementia has yet to be determined. Objective: To examine if sex modifies the association between marital status and incident dementia. Methods: Population-based samples from the Mayo Clinic Study of Aging (MCSA, N = 3,471) and the Gothenburg H70 Birth Cohort Study (H70-study, N = 913) were used. A multiplicative interaction term was used to analyze the modifying effect of sex on the relation between marital status (married versus not married) and incident dementia using Cox regression models. Further, risk of dementia by marital status was also evaluated in models separated by sex. Results: In the MCSA, there was an interaction between marital status and sex in relation to dementia (p = 0.015). In contrast, in the H70-study, no significant interaction was observed (p = 0.28). Nevertheless, in both studies, not married men had increased risk of dementia compared to married men in models adjusted for age, education, and number of children (H70-study: 1.99; 1.06–3.76, MCSA: 1.43; 1.08–1.89). Associations remained similar after additional adjustment for depression, BMI, hypertension, dyslipidemia, and diabetes mellitus (H70-study: 2.00; 1.05–3.82, MCSA: 1.32; 0.99–1.76). Further, no significant association was observed between marital status and dementia in women (H70-study: 1.24; 0.82–1.89, MCSA: 0.82; 0.64–1.04). Conclusion: Sex had a modifying effect on the association between marital status and incident dementia. In analyses separated by sex, not married men had an increased risk of dementia compared to married men, while no significant association was observed between marital status and risk of dementia in women.

Abstract Introduction/Purpose: There is a general lack of consensus onboth the anatomic definition and function of Broca’s area. Given the belief that this region plays a critical role in expressive language, resective surgery is often avoided topreserve function. However, the putative role of Broca’s area in speech production has been recently challenged.The current study aims to investigatethe feasibilityof glioma resection and neurological outcomes in “Broca’s area” in 15 patients.Methods: We report a feasibility study describing the resection of gliomas within the IFG. Awake brain surgery for resection with mapping and intraoperative neuropsychological evaluation was carried out in all individuals. Results: All included patientshad tumors located in traditional “Broca’s area” and eight patients (53.33%) had tumors that additionally extendedinto the insula and subinsular regions. During stimulation, positive speech-language sites within the IFG were identified in ten patients. Two patients (13.33%) experienced a declinein naming during intraoperative cognitive monitoring and thirteen (86.66%) had a stable performance throughout surgery. With all patients had recovery of language functions at a two-week follow up. Extent of resection was stratified in anatomical regions within the IFG, being the pOr the area with the greatest EOR (97.4%), followed by the pT (84.1%), pOp (83.8%), and vPMC (80%).Conclusion: The belief that Broca’s area is not safe to resect is challenged. Adequate mapping and careful patient selection allow maximum safe resection of tumors located in thetraditional “Broca’s area”,with low risk of postoperative morbidity.
