Endoscopic scoring system utilization for inflammatory bowel disease activity assessment: A multicenter real-world study from Argentina.

BACKGROUND: The frequency and patterns of use of scores for the assessment of endoscopic activity in inflammatory bowel disease patients are not known. AIM: To describe the prevalence of adequate use of endoscopic scores in IBD patients who underwent colonoscopy in a real-life setting. MATERIALS AND METHODS: A multicenter observational study comprising six community hospitals in Argentina was undertaken. Patients with a diagnosis of Crohn's disease or ulcerative colitis who underwent colonoscopy for endoscopic activity assessment between 2018 and 2022 were included. Colonoscopy reports of included subjects were manually reviewed to determine the proportion of colonoscopies that included an endoscopic score report. We determined the proportion of colonoscopy reports that included all of the IBD colonoscopy report quality elements proposed by BRIDGe group. Endoscopist's specialty, years of experience as well as expertise in IBD were assessed. RESULTS: A total of 1556 patients were included for analysis (31.94% patients with Crohn's disease). Mean age was 45.94±15.46. Endoscopic score reporting was found in 58.41% of colonoscopies. Most frequently used scores were Mayo endoscopic score (90.56%) and SES-CD (56.03%) for ulcerative colitis and Crohn's disease, respectively. In addition, 79.11% of endoscopic reports failed to comply with all recommendations on endoscopic reporting for inflammatory bowel disease. CONCLUSIONS: A significant proportion of endoscopic reports of inflammatory bowel disease patients do not include the description of an endoscopic score to assess mucosal inflammatory activity in a real-world setting. This is also associated with a lack of compliance in recommended criteria for proper endoscopic reporting.

Assessment of EPInfant scale for exercise intensity perceptual self-regulation in healthy children. / Evaluación de la escala EPInfant para la auto-regulación perceptual de la intensidad del ejercicio en niños sanos.

INTRODUCTION: The EPInfant scale has been validated for the perceptual estimation of physical exer tion in Chilean children, but its usefulness for self-regulation of exercise intensity is unknown. The objective of the study was to evaluate the criterion validity of the EPInfant scale to regulate and re produce exercise intensity in a sample of healthy children. SUBJECTS AND METHOD: 15 children between the ages of eight and 12 were selected for an incremental exercise test (IET) and three perceptually regulated exercise tests (PRET) on a treadmill. The tests were performed with a 48-hour interval between them. In the PRET, the exercise load was adjusted perceptually for five minutes, randomly considering levels 3, 6, and 9 of the EPInfant scale. The average heart rate (HR) during PRET was considered as the perceptually reproduced intensity. Variance analysis, simple linear regression, and reliability analysis were used to determine the reproducibility of HR during PRET. RESULTS: There was a significant difference in HR between perceptual levels during PRET (p < 0.001). Additionally, a correlation was observed between HR during the IET and the PRET (r = 0.83, r2 = 0.69). The intra class correlation coefficient was 0.76, 0.83. and 0.93 at perceptual levels 3, 6, and 9; and the mean dis cordance between HR during the IET and the PRET was -2.4 beats/min. CONCLUSION: In the studied sample, the EPInfant scale was valid to allow the perceptual regulation and reproduction of exercise intensity in a treadmill.

Evaluación de la escala EPInfant para la auto-regulación perceptual de la intensidad del ejercicio en niños sanos / Assessment of EPInfant scale for exercise intensity perceptual self-regulation in healthy children

INTRODUCCIÓN: La escala EPInfant ha sido validada para la estimación perceptual del esfuerzo físico en niños chile nos, pero se desconoce su utilidad para la autorregulación de la intensidad del ejercicio. OBJETIVO: evaluar la validez de criterio de la escala EPInfant para regular y reproducir la intensidad de ejercicio en una muestra de niños sanos. SUJETOS Y MÉTODO: Se seleccionaron 15 niños entre 8 y 12 años, en quienes se realizó un test de carga incremental (TCI) y tres pruebas de regulación perceptual (PRP) en trotadora. Las pruebas se realizaron con un intervalo de 48 horas entre ellas. En la PRP, la carga de trabajo se ajustó perceptualmente durante 5 minutos, considerando aleatoriamente los niveles 3, 6 y 9 de la escala EPInfant. Se consideró el promedio de la FC durante la PRP como la intensidad reproducida perceptualmente. Se empleó análisis de varianza, regresión lineal simple y análisis de confiabilidad para determinar la reproducibilidad de la FC durante la PRP. RESULTADOS: Existió diferencia significativa en la FC entre los niveles perceptivos durante la PRP (p < 0,001). Adicional mente, se observó correlación entre la FC durante el TCI y la PRP (r = 0,83; r2 = 0,69). El coeficiente de correlación intraclase fue de 0,76, 0,83 y 0,93 en los niveles perceptivos 3, 6 y 9; y la discordancia media entre la FC durante el TCI y la PRP fue de -2,4 lat/min. CONCLUSIÓN: En la muestra estudiada, la escala EPInfant fue válida para permitir la regulación y reproducción perceptual de la intensidad del ejercicio en trotadora.

Efficacy of Different Treatment Alternatives for Obesity Hypoventilation Syndrome. Pickwick Study.

RATIONALE: The incidence of obesity hypoventilation syndrome (OHS) may be increasing in parallel with the present obesity epidemic. Despite extensive noninvasive ventilation (NIV) and continuous positive airway pressure (CPAP) use in patients with OHS, information regarding efficacy is limited. OBJECTIVES: We performed a large, multicenter randomized controlled study to determine the comparative efficacy of NIV, CPAP, and lifestyle modification (control group) using daytime PaCO2 as the main outcome measure. METHODS: Sequentially screened patients with OHS with severe sleep apnea were randomized into the above-mentioned groups for a 2-month follow up. Arterial blood gas parameters, clinical symptoms, health-related quality-of-life assessments, polysomnography, spirometry, 6-minute-walk distance, dropouts, compliance, and side effects were evaluated. Statistical analysis was performed using intention-to-treat analysis, although adjustments for CPAP and NIV compliance were also analyzed. MEASUREMENTS AND MAIN RESULTS: In total, 351 patients were selected, and 221 were randomized. NIV yielded the greatest improvement in PaCO2 and bicarbonate, with significant differences relative to the control group but not relative to the CPAP group. In the CPAP group, PaCO2 improvement was significantly different than in the control group only after CPAP compliance adjustment. Additionally, clinical symptoms and polysomnographic parameters improved similarly with NIV and CPAP relative to the control. However, some health-related quality-of-life assessments, the spirometry, and 6-minute-walk distance results improved more with NIV than with CPAP. Dropouts were similar between groups, and compliance and secondary effects were similar between NIV and CPAP. CONCLUSIONS: NIV and CPAP were more effective than lifestyle modification in improving clinical symptoms and polysomnographic parameters, although NIV yielded better respiratory functional improvements than did CPAP. Long-term studies must demonstrate whether this functional improvement has relevant implications. Clinical trial registered with www.clinicaltrials.gov (NCT01405976).
