Janowitz Division of Gastroenterology, Icahn School of Medicine at Mount Sinai, New York, NY, USACorrespondence: Ipek Ensari, Department of Artificial Intelligence and Human Health, Icahn School of Medicine at Mount Sinai, New York, NY, USA, Email [email protected]: Female chronic pelvic pain disorders (CPPDs) affect 1 in 7 women worldwide and are characterized by psychosocial comorbidities, including a reduced quality of life and 2– 10-fold increased risk of depression and anxiety. Despite its prevalence and morbidity, CPPDs are often inadequately managed with few patients experiencing relief from any medical intervention. Characterizing mental health symptom trajectories and lifestyle predictors of mental health is a starting point for enhancing patient self-efficacy in managing symptoms. Here, we investigate the association between mental health, pain, and physical activity (PA) in females with CPPD and demonstrate a method for handling multi-modal mobile health (mHealth) data.Methods: The study sample included 4270 person-level days and 799 person-level weeks of data from CPPD participants (N=76). Participants recorded PROMIS global mental health (GMH) and physical functioning and pain weekly for 14 weeks using a research mHealth app, and moderate-to-vigorous PA (MVPA) was passively collected via activity trackers.Data Analysis: We used penalized functional regression (PFR) to regress weekly GMH-T (GMH-T) on MVPA and weekly pain outcomes while adjusting for baseline measures, time in study, and the random intercept of the individual. We converted 7-day MVPA data into a single smooth using spline basis functions to model the potential non-linear relationship.Results: MVPA was a significant, curvilinear predictor of GMH-T (F=18.989, p< 0.001), independent of pain measures and prior psychiatric diagnosis. Physical functioning was positively associated with GMH-T, while pain was negatively associated with GMH-T (B=2.24, B=− 1.16, respectively; p< 0.05).Conclusion: These findings suggest that engaging in MVPA is beneficial to the mental health of females with CPPD. Additionally, this study demonstrates the potential of ambulatory mHealth-based data combined with functional models for delineating inter-individual and temporal variability.Keywords: chronic pelvic pain, digital health, functional data modeling, global mental healt

Uso de adesivos teciduais em cirurgia digestiva

INTRODUÇÃO: Apesar dos refinamentos em cirurgia gastrointestinal, vazamentos anastomóticos persistem como grave problema, associados à morbidade e mortalidade elevadas e constituem a complicação mais temida. Na tentativa de prevenir e reduzir estas complicações, diversidade de técnicas de reforço anastomótico tem sido investigada e diversas medidas auxiliares têm sido desenvolvidas. OBJETIVO: Revisar os dados associados a aplicação de adesivos em cirurgia digestiva. MÉTODO: Revisão bibliográfica de artigos disponíveis no Medline/Pubmed utilizando-se os descritores: adesivo, trato gastrointestinal, anastomose cirúrgica e fístula. Foram selecionados os artigos mais atualizados sobre o assunto os quais utilizaram adesivos como estratégia para reduzir a morbidade e mortalidade relacionada à cirurgia digestiva. CONCLUS��O: Adesivos teciduais parecem seguros na prática clínica e têm sido utilizados com crescente frequência em várias especialidades cirúrgicas em decorrência de suas propriedades hemostáticas e selante, ganhando cada vez maior aceitação por parte dos cirurgiões. Estudos sugerem que adesivos cirúrgicos podem reforçar e melhorar a cicatrização de anastomoses intestinais, elevando a pressão de ruptura e aumentando a força tênsil. Os potenciais efeitos deletérios teciduais destas substâncias podem limitar sua utilização. Em decorrência da heterogeneidade dos estudos e falta de evidência forte, novas pesquisas deverão ser desenvolvidas.BACKGROUND: Despite refinements in the field of gastrointestinal surgery, anastomotic leakage still remains a serious problem associated with substantial morbidity and mortality and is the fearest life threatening complication in digestive surgery. To prevent or reduce these complications, a diversity of line reinforcement techniques have been investigated and several adjunctive measures have been developed. AIM: To review the data associated with the application of adhesives in digestive surgery procedures. METHOD: Review of papers available at Medline/Pubmed database using the follow headings: adhesive, gastrointestinal tract, surgical anastomosis, fistula. It was chosen recent articles on the subject which showed adhesives as strategy to reduce morbidity and mortality related to digestive surgery. CONCLUSION: Tissue adhesives appears to be safe in the clinical setting and are been used with increasing frequency in a variety of surgical field for its unique hemostatic and adhesive abilities, gaining increasing acceptance among surgeons. Studies suggest that surgical adhesive can be useful to reinforce and improve intestinal anastomotic healing, increase anastomotic bursting pressures and tensile strength. The potentially harmful tissue effects of the preparations might compromise the use of these substances. Because of the heterogeneity and lack of high level evidence, new studies have to be performed

New entity of adult ultra-short coeliac disease: the first international cohort and case–control study

Background: Ultra-short coeliac disease (USCD) is defined as villous atrophy only present in the duodenal bulb (D1) with concurrent positive coeliac serology. We present the first, multicentre, international study of patients with USCD. Methods: Patients with USCD were identified from 10 tertiary hospitals (6 from Europe, 2 from Asia, 1 from North America and 1 from Australasia) and compared with age-matched and sex-matched patients with conventional coeliac disease. Findings: Patients with USCD (n=137, median age 27 years, IQR 21–43 years; 73% female) were younger than those with conventional coeliac disease (27 vs 38 years, respectively, p<0.001). Immunoglobulin A-tissue transglutaminase (IgA-tTG) titres at index gastroscopy were lower in patients with USCD versus conventional coeliac disease (1.8×upper limit of normal (ULN) (IQR 1.1–5.9) vs 12.6×ULN (IQR 3.3–18.3), p<0.001). Patients: with USCD had the same number of symptoms overall (median 3 (IQR 2–4) vs 3 (IQR 1–4), p=0.875). Patients with USCD experienced less iron deficiency (41.8% vs 22.4%, p=0.006). Both USCD and conventional coeliac disease had the same intraepithelial lymphocytes immunophenotype staining pattern; positive for CD3 and CD8, but not CD4. At follow-up having commenced a gluten-free diet (GFD) (median of 1181 days IQR: 440–2160 days) both USCD and the age-matched and sex-matched controls experienced a similar reduction in IgA-tTG titres (0.5 ULN (IQR 0.2–1.4) vs 0.7 ULN (IQR 0.2–2.6), p=0.312). 95.7% of patients with USCD reported a clinical improvement in their symptoms. Interpretation: Patients with USCD are younger, have a similar symptomatic burden and benefit from a GFD. This study endorses the recommendation of D1 sampling as part of the endoscopic coeliac disease diagnostic workup

Examining the generalizability of research findings from archival data

This initiative examined systematically the extent to which a large set of archival research findings generalizes across contexts. We repeated the key analyses for 29 original strategic management effects in the same context (direct reproduction) as well as in 52 novel time periods and geographies; 45% of the reproductions returned results matching the original reports together with 55% of tests in different spans of years and 40% of tests in novel geographies. Some original findings were associated with multiple new tests. Reproducibility was the best predictor of generalizability—for the findings that proved directly reproducible, 84% emerged in other available time periods and 57% emerged in other geographies. Overall, only limited empirical evidence emerged for context sensitivity. In a forecasting survey, independent scientists were able to anticipate which effects would find support in tests in new samples

Cognitive Motor Interference in Multiple Sclerosis: Insights From a Systematic Quantitative Review

OBJECTIVE: To synthesize the evidence for differences in cognitive motor interference (CMI) between persons with multiple sclerosis (MS) and those without MS by using systematic review and meta-analysis. DATA SOURCES: EMBASE, PubMed, ScienceDirect, Scopus, SPORTDiscus, and Web of Science. Our focused literature search was informed by past systematic reviews of CMI during walking in MS. STUDY SELECTION: The key terms searched included Multiple sclerosis and synonyms of motor function (eg, Gait disorders, Gait, Walking, Balance, or Fall) and motor and cognitive functions (eg, Cognitive motor interference or Thinking). DATA EXTRACTION: From the 116 abstract-identified articles, 13 experimental studies were selected for the final analysis and were rated using the Quality Assessment of Diagnostic Accuracy Studies tool. A meta-analysis was performed for all considered outcomes. DATA SYNTHESIS: The results yielded a small overall effect size (ES) of .08 (SE=.17; 95% confidence interval, -.25 to .40; z=.49; P>.05), which indicated a nonsignificant minimal difference in CMI between persons with MS and those without MS. The moderator analysis for motor task (mobility task: ES, .22; postural task: ES, -.11) was not significantly different between persons with MS and those without MS. The moderator analysis for cognitive task (verbal fluency task: ES, .66; mental tracking task: ES, .04; discrimination and decision-making task: ES, -.30) resulted in a significant difference in CMI between persons with MS and those without MS (P<.05). CONCLUSIONS: We provide evidence that overall there is a minimal difference in CMI between persons with MS and those without MS

Physiotherapy and walking outcomes in adults with multiple sclerosis: Systematic review and meta-analysis

Background: Physiotherapy treatment may result in improved walking performance among persons with multiple sclerosis (MS). The existing literature is unclear as to what type of physiotherapy treatment has a larger effect on walking performance. It is further unclear regarding which domain of walking performance is improved with physiotherapy. Objective: To systematically review and quantify the effect of physiotherapy on walking performance compared with usual care in MS. Methods: A literature search of five databases was undertaken to identify randomised controlled trials of physiotherapy treatments that targeted walking outcomes. There were 21 studies that met our inclusion criteria and yielded data for effect size (ES) generation. An overall ES was calculated using a random effects model and expressed as Hedge’s g. Major findings: Physiotherapy treatments yielded a small, but statistically significant overall improvement in walking outcomes compared with usual care in persons with MS (ES = 0.25; 95% CI = 0.09–0.41; p < .05). Moderator analyses provided no significant evidence that different types of physiotherapy treatment, or different domains of walking performance, yield larger improvements in walking outcomes in persons with MS. Conclusion: This evidence indicates that overall there is a significant improvement in walking performance following physiotherapy in persons with MS

Accuracy of StepWatch™ and ActiGraph accelerometers for measuring steps taken among persons with multiple sclerosis

Introduction There has been increased interest in the objective monitoring of free-living walking behavior using accelerometers in clinical research involving persons with multiple sclerosis (MS). The current investigation examined and compared the accuracy of the StepWatch activity monitor and ActiGraph model GT3X+ accelerometer for capturing steps taken during various speeds of prolonged, over-ground ambulation in persons with MS who had mild, moderate, and severe disability. Methods Sixty-three persons with MS underwent a neurological examination for generation of an EDSS score and undertook two trials of walking on the GAITRite electronic walkway. Participants were fitted with accelerometers, and undertook three modified six-minute walk (6MW) tests that were interspersed with 10–15 minutes of rest. The first 6MW was undertaken at a comfortable walking speed (CWS), and the two remaining 6MW tests were undertaken above (faster walking speed; FWS) or below (slower walking speed; SWS) the participant's CWS. The actual number of steps taken was counted through direct observation using hand-tally counters. Results The StepWatch activity monitor (99.8%–99.9%) and ActiGraph model GT3X+ accelerometer (95.6%–97.4%) both demonstrated highly accurate measurement of steps taken under CWS and FWS conditions. The StepWatch had better accuracy (99.0%) than the ActiGraph (95.5%) in the overall sample under the SWS condition, and this was particularly apparent in those with severe disability (StepWatch: 95.7%; ActiGraph: 87.3%). The inaccuracy in measurement for the ActiGraph was associated with alterations of gait (e.g., slower gait velocity, shorter step length, wider base of support). Conclusions This research will help inform the choice of accelerometer to be adopted in clinical trials of MS wherein the monitoring of free-living walking behavior is of particular value
