RESUMO

BACKGROUND AND AIMS: Screening colonoscopy has significantly contributed to the reduction of the incidence of colorectal cancer (CRC) and its associated mortality, with adenoma detection rate (ADR) as the quality marker. To increase the ADR, various solutions have been proposed including the utilization of Artificial Intelligence (AI) and employing second observers during colonoscopies. In the interest of AI improving ADR independently, without a second observer, and the operational similarity between AI and second observer, this network meta-analysis aims at evaluating the effectiveness of AI, second observer, and a single observer in improving ADR. METHODS: We searched the Medline, Embase, Cochrane, Web of Science Core Collection, Korean Citation Index, SciELO, Global Index Medicus, and Cochrane. A direct head-to-head comparator analysis and network meta-analysis were performed using the random-effects model. The odds ratio (OR) was calculated with a 95% confidence interval (CI) and p-value < 0.05 was considered statistically significant. RESULTS: We analyzed 26 studies, involving 22,560 subjects. In the direct comparative analysis, AI demonstrated higher ADR (OR: 0.668, 95% CI 0.595-0.749, p < 0.001) than single observer. Dual observer demonstrated a higher ADR (OR: 0.771, 95% CI 0.688-0.865, p < 0.001) than single operator. In network meta-analysis, results were consistent on the network meta-analysis, maintaining consistency. No statistical difference was noted when comparing AI to second observer. (RR 1.1 (0.9-1.2, p = 0.3). Results were consistent when evaluating only RCTs. Net ranking provided higher score to AI followed by second observer followed by single observer. CONCLUSION: Artificial Intelligence and second-observer colonoscopy showed superior success in Adenoma Detection Rate when compared to single-observer colonoscopy. Although not statistically significant, net ranking model favors the superiority of AI to the second observer.

RESUMO

BACKGROUND: Management of choledocholithiasis in patients with Roux-en-Y gastric bypass surgery is challenging. This study aims to compare technical success rates, adverse events, and procedural time between 3 current approaches: endoscopic ultrasound-directed transgastric Endoscopic retrograde cholangiopancreatography (ERCP) (EDGE), enteroscopy-assisted ERCP (E-ERCP), and laparoscopic-assisted ERCP (LA-ERCP). METHODS: A systematic search of 5 databases was conducted. Direct and network meta-analyses were performed to compare interventions using the random effects model. A significance threshold of P < 0.05 was applied. RESULTS: Sixteen studies were included. On direct meta-analysis, technical success rates were comparable between EDGE and LA-ERCP (odds ratio: 0.768, CI: 0.196-3.006, P = 0.704, I2 = 14.13%). However, EDGE and LA-ERCP showed significantly higher success rates than E-ERCP. No significant differences in adverse events were found between EDGE versus LA-ERCP, EDGE versus E-ERCP, and LA-ERCP versus E-ERCP on direct meta-analysis. In terms of procedural time, EDGE was significantly shorter than E-ERCP [mean difference (MD): -31 minutes, 95% CI: -40.748 to -21.217, P < 0.001, I2 = 19.89%), and E-ERCP was shorter than LA-ERCP (MD: -44.567 minutes, 95% CI: -76.018 to -13.116, P = 0.005, I2 = 0%). EDGE also demonstrated a significant time advantage over LA-ERCP (MD: -78.145 minutes, 95% CI: -104.882 to -51.407, P < 0.001, I2 = 0%). All findings were consistent with network meta-analysis on random effects model. The heterogeneity of the model was low. CONCLUSIONS: EDGE and LA-ERCP showed superior technical success rates compared with E-ERCP. Adverse events did not significantly differ among the three approaches. Furthermore, EDGE demonstrated the shortest procedural duration. We recommend considering EDGE as a first-choice procedure.

RESUMO

PURPOSE OF REVIEW: The purpose of this review was to investigate and synthesize psychosocial outcomes from pharmacotherapy experimental trials for weight loss among adolescents with obesity. RECENT FINDINGS: There is a paucity of research regarding pharmacological interventions for adolescents with obesity. These studies have typically reported reductions in weight, and side effects have been inconsistently described. Overall, medication seems to be a safe and effective obesity treatment modality for adolescents with obesity. Six articles were included in this review. Studies varied in medication type, medication dosing, lifestyle components, psychosocial measures, measurement intervals, and psychosocial outcomes. All studies found a reduction in weight and/or BMI. Studies were often underpowered to detect differences in psychosocial variables, which were always considered secondary or exploratory outcomes. Future research should include psychosocial outcomes as a primary endpoint of pharmacological interventions for adolescent obesity. Ultimately, the treatment of the complex disease of obesity deserves to be assessed through multiple health domains extending beyond weight reduction.

RESUMO

Objective: Effectiveness of behavioural obesity treatments in adolescents is modest. Thus, incorporating participant feedback may lead to improvement of intervention acceptability. This qualitative study's objective was to assess perceived barriers/facilitators to weight loss and healthy lifestyles among diverse adolescents with overweight/obesity (OW/OB). Methods: Adolescents ages 14-19 with BMI ≥ 85th percentile participated in focus groups and identified perceived barriers/facilitators to weight loss and healthy lifestyles. Results: Ten sex-stratified focus groups (n = 41; n = 13 males, n = 28 females) were conducted in 2018 and 2019. Females reported experiencing weight struggles, whereas males often stated no struggles with weight, despite all participants meeting criterion for OW/OB. Barriers included eating behaviours, family members and internal motivation, with additional barriers of physical activity, friends, time and support cited in females. Facilitators included parental, familial and peer support of healthy eating and exercise, modelling behaviours, internal motivation and organized sports. Two additional findings regarding adolescents' perceived barriers/facilitators include substantial overlap and sex differences of perceived barriers/facilitators. Conclusions: Adolescent males and females with OW/OB experience weight status differently, affecting their perceived barriers/facilitators to weight loss and healthy lifestyles. Tailoring weight management interventions to the unique needs of adolescent females versus adolescent males has the potential to improve intervention quality and effectiveness.

RESUMO

Diabetes is a complex and multifactorial disease affecting more than 415 million people worldwide. Excess adiposity and modifiable lifestyle factors, such as unhealthy dietary patterns and physical inactivity, can play a significant role in the development of type 2 diabetes. Interventions that implement changes to lifestyle behaviors, in addition to pharmacological treatment, may attenuate the development and worsening of diabetes. This narrative review delineates how standard behavioral interventions (SBTs), based in "first wave" behavioral therapies and "second wave" cognitive behavioral therapies, serve as the foundation of diabetes treatment by supporting effective lifestyle changes, including improving adherence to healthful behaviors, medication, and self-monitoring regimens. Moreover, "third wave" "acceptance-based therapies" (ABTs), which integrate techniques from acceptance and commitment therapy, are proposed as a potential novel treatment option for diabetes management. Further research and long-term, randomized controlled trials will clarify the feasibility, acceptability, and effectiveness of ABT for improving glucose control via enhancing medication adherence and promoting effective lifestyle changes in people with diabetes.

RESUMO

Eating behaviors, including unhealthy snacking or excessive snacking leading to excess calorie consumption, may contribute to obesity among adolescents. Socioeconomic status (SES) also significantly influences eating behaviors, and low SES is associated with increased risk for obesity. However, little is known regarding the relationship between snacking behavior and SES among adolescents and how this may contribute to obesity-related outcomes. The primary objective of this scoping review was to review the literature to assess and characterize the relationship between SES and snacking in adolescents. The secondary objective was to assess weight-related outcomes and their relation to snacking habits. Included articles were published between January 2000 and May 2019; written in English, Portuguese, or Spanish; and focused on adolescents (13-17 years). In total, 14 bibliographic databases were searched, and seven studies met the inclusion criteria. Preliminary evidence from the seven included studies suggests a weak but potential link between SES and snacking. Additionally, these dietary patterns seemed to differ by sex and income type of country. Finally, only three of the included studies addressed weight-related outcomes, but the overall available evidence suggests that snacking does not significantly affect weight-related outcomes. Due to the small number of included studies, results should be interpreted with caution.
