“…We also observed a statistically significant change in the mean (±SD) 30‐second sit‐to‐stand test of 4 (±4) counts, which is approximately 2‐fold greater than changes reported in recent studies following bariatric surgery plus exercise intervention . Improvements in leg strength and endurance were inversely associated with BMI (positively associated with weight loss) age and diabetes.…”

Physical capacity outcomes in patients with severe obesity after 12 months of physician‐led multidisciplinary team care: A case series from a public hospital clinical obesity service

et al. 2019

Summary Impaired physical capacity is common in people with severe levels of obesity. We aimed to investigate changes in physical capacity outcomes in patients with severe obesity following 12 months of physician‐led multidisciplinary care from a “real world” Australian public hospital setting using a case series study design. We extracted data from medical records for all of the eligible patients referred to our clinical obesity service from 2010 to 2015 (69 of 239). We found significant (P < .05) pre‐test/post‐test (mean ± SD) improvements in the 6‐minute walk test (6MWT) (339 ± 120 to 417 ± 112 m); 30‐second sit‐to‐stand test (11 ± 4 to 15 ± 6 counts) and sit‐and‐reach test (−12 ± 13 to −8 ± 15 cm). Using linear mixed‐effects models adjusting for repeated measurements over time (baseline vs 12 months) and testing for potential predictors, we found: mean 6MWT was associated with 12‐month time period (56 m), body mass index (BMI, −3 m), no walking aid over 12 months (106 m) and no opioid analgesics (75 m); mean sit‐to‐stand was associated with 12‐month time period (3 counts), age at referral (−0.2 counts), BMI (−0.2 counts), and diabetes (3 counts); and mean sit‐and‐reach was associated with 12‐month time period (5 cm), female gender (5 cm) and total medications (−0.9 cm). Using causal mediation analysis, our results show that total exercise classes partially mediates change in walking capacity among those with cardiovascular disease. Our study shows that significant and clinically important improvements in physical capacity outcomes in patients with severe obesity can be achieved following 12 months of intensive specialist obesity services, such as ours.

“…For example, the three‐arm trial by Hassannejad et al reported in the abstract that both intervention arms were better than control for the primary endpoint of weight loss; however, they did not report the comparison between intervention arms, possibly because this comparison was not statistically significant. The only mention in the abstract of a between‐intervention comparison was for the secondary endpoint, which was statistically significant …”

Evaluation of spin within abstracts in obesity randomized clinical trials: A cross‐sectional review

et al. 2018

View full text Add to dashboard Cite

This is a cross-sectional analysis of spin in randomized controlled trial (RCT) abstracts published in top-ranked obesity and general medicine journals. The top seven obesity and four general medicine journals were searched from 1 January 2016 to 31 December 2017. To be included in this study, a trial must be an RCT with non-significant primary endpoint (P > 0.05), exclusively randomize subjects with overweight or obesity or have a primary endpoint of weight loss. These studies were analysed by two reviewers for spin in the abstract.The primary endpoint of our investigation was the frequency and type of spin. The secondary endpoint was to assess whether funding source was associated with the presence of spin. Our PubMed search yielded 1143 articles. Primary screening excluded 992 articles, and fulltext evaluation excluded an additional 106. Overall, 45 articles were included. Spin was identified in 21 of the 45 (46.7%) abstracts analysed. Evidence of spin was found in 17 (37.8%) abstract result sections and 11 (24.4%) abstract conclusion sections. Of the 39 RCTs reporting a clinical trial registry, 6 (15.4%) had evidence of selective reporting bias. Our study found that obesity medicine RCTs from top-ranked journals with non-significant primary endpoints published in 2016 and 2017 frequently have spin in their abstracts. Abstracts with evidence of spin may influence a reader's perception of new drugs or procedures. These results warrant a careful review of future RCTs, but may not be generalizable to RCTs published in lower-ranked journals.

“…En el paciente bariátrico, el objetivo de la evaluación es determinar la capacidad cardiorrespiratoria a través de una prueba de estrés cardiopulmonar que nos permita prescribir el ejercicio aeróbico y evaluar la respuesta al entrenamiento, teniendo en consideración sus experiencias previas habitualmente negativas relacionadas con el ejercicio y/o actividad física 8 . En la literatura revisada en la Tabla 2 6,[9][10][11][12][13][14][15][16][17][18] , la metodología más utilizadas es la evaluación directa del consumo máximo (VO 2max ) o pico de oxígeno mediante ergoespirometría, utilizando protocolos escalonados con duración de 5-12 min. Dentro de las evaluaciones indirectas la realización del protocolo de Astrand o Bruce puede entregar una estimación del VO 2max 19 y parámetros de carga interna y/o externa para la prescripción del ejercicio.…”

The Effect of Aerobic or Aerobic-Strength Exercise on Body Composition and Functional Capacity in Patients with BMI ≥35 after Bariatric Surgery: a Randomized Control Trial

Abstract: The data suggests a positive effect of exercise on weight and PBF decrease after surgery, and it leads to significant improvement on aerobic capacity. Moreover, doing resisted exercise caused greater preserving of lean mass.
