RESUMEN
BACKGROUND: Childhood obesity is a major global health concern. Weight-management camps involving delivery of a program of physical activity, health education, and healthy eating are an effective treatment, although post-intervention weight-management is less well understood. Our objective was to assess the effectiveness of a weight-management camp followed by a community intervention in supporting weight-management for overweight children and children with obesity. METHODS: Participants were overweight Qatari schoolchildren or schoolchildren with obesity, ages 8-14 years, (n = 300) recruited over a three-year period across 14 randomly selected schools in the Doha area. They attended a two-week weight management camp, then a 10-week program of weekly lifestyle education and physical activity sessions, which also included behavior change techniques. The programme was cognitive behavioural therapy (CBT)-focused with a strong element of behavioural economics blended in. RESULTS: Participants saw a significant BMI SDS reduction as a result of the entire intervention (camp + education and activity sessions) both at the individual (p < 0.0001) and cluster/school (p = 0.0002) levels, and weight loss occurred during each intervention stage separately for the camp (p < 0.0001 for both the individual and cluster/school levels) and the lifestyle education and activity phase (p < 0.0001 and p = 0.0220 at the individual and cluster/school levels, respectively). CONCLUSIONS: Weekly lifestyle education and activity sessions which include behavior change techniques may be useful in promoting continued weight management in the period following intensive, immersive childhood obesity interventions.

BACKGROUND: Recovery from surgery has traditionally been measured using specific outcome measures, such as length of hospital stay. However, advances in technology have enabled the measurement of continuous, objective physical activity data in the perioperative period. The aim of this systematic review was to determine the relationship between length of hospital stay and physical activity data for patients undergoing surgery. METHODS: A systematic search of EMBASE, Medline and the Cochrane Library, from inception until January 2017, was performed to identify all study designs that evaluated physical activity after surgery. Studies were included if a wearable sensor measured patient activity as an in-patient and the length of hospital stay was reported. Only English articles were included. RESULTS: Six studies with a total of 343 participants were included in this review. All the studies were prospective observational studies. Each study used a different sensor, with the commonest being a tri-axial accelerometer, and multiple different physical activity outcome measures were used, thereby prohibiting meta-analysis. Four of the studies demonstrated a relationship between physical activity levels and length of hospital stay, while two studies did not show any significant relationship. CONCLUSION: The amount of physical activity performed post-operatively negatively correlates with the length of hospital stay. This suggests that objective physical activity data collected by body worn sensors may be capable of predicting functional recovery post-operatively.

Since the concept of enhanced recovery after surgery (ERAS) was introduced in the late 1990s the idea of implementing specific interventions throughout the peri-operative period to improve patient recovery has been proven to be beneficial. Minimally invasive surgery is an integral component to ERAS and has dramatically improved post-operative outcomes. ERAS can be applicable to all surgical specialties with the core generic principles used together with added specialty specific interventions to allow for a comprehensive protocol, leading to improved clinical outcomes. Diffusion of ERAS into mainstream practice has been hindered due to minimal evidence to support individual facets and lack of method for monitoring and encouraging compliance. No single outcome measure fully captures recovery after surgery, rather multiple measures are necessary at each stage. More recently the pre-operative period has been the target of a number of strategies to improve clinical outcomes, described as prehabilitation. Innovation of technology in the surgical setting is also providing opportunities to overcome the challenges within ERAS, e.g., the use of wearable activity monitors to record information and provide feedback and motivation to patients peri-operatively. Both modernising ERAS and providing evidence for key strategies across specialties will ultimately lead to better, more reliable patient outcomes.
RESUMEN
BACKGROUND: Rectal intussusception and external rectal prolapse are uncommon proctographic findings in men reflecting the lack of studies investigating such patients. The aim of this study was to identify the demographic, clinical, and physiological characteristics of this population with a view to appreciate the mechanism of development of this condition. METHODS: All men, presenting with symptoms of constipation or fecal incontinence, who were diagnosed proctographically with recto-rectal intussusception (RRI)/recto-anal intussusception (RAI) or external rectal prolapse (ERP) between 1994 and 2007 at a tertiary academic colorectal unit were studied. Demographics, relevant comorbidities, distribution and symptom duration, and anorectal physiology results were analyzed retrospectively for each proctographic group and intergroup comparisons performed. RESULTS: Two hundred five men (median age 50 y; range, 13-86) including 155 (75.6%) without any relevant comorbidities were studied. A significant proportion of patients in all proctographic groups reported rectal evacuatory difficulty ([RRI, 46.4%], [RAI, 39.4%], [ERP, 44.8%]; P = 0.38,analysis of variance). Patients also reported a combination of fecal incontinence symptoms (e.g., urge, passive, postdefecatory leakage) that did not differ across the proctographic groups. Anorectal physiological parameters were within normal range and were not found to be statistically different between the proctographic groups with the exception of anal resting pressure, which was lowest in ERP patients (62 cm H2O; range, 14-155) compared with patients with RRI (89 cm H2O; range, 16-250; P = 0.003) and RAI (92 cm H2O; range, 38-175; P = 0.006). CONCLUSIONS: Men with rectal intussusception and prolapse present with a combination of symptoms, predominantly defective rectal evacuation. Anorectal physiological assessment has failed to shed light into the mechanism of development of this condition and thus, the need for large observational studies incorporating integrated defecographic and manometric assessments of the evacuation process.

BACKGROUND: Diverticular disease is the most common morphological abnormality of the colon and the fifth most important gastrointestinal disease in terms of cost in the Western world. Tower Hamlets is the poorest borough in London containing a large Bangladeshi community. We observed that emergency admissions with complications of colonic diverticulosis were minimal in the Bangladeshi community. The objective was to compare the background prevalence of colonic diverticulosis in Bangladeshis with other ethnicities in patients undergoing colonoscopy at a single centre in Tower Hamlets. METHODS: Four thousand four hundred and fifty-four consecutive colonoscopy reports over a 2-year period were retrospectively analysed. Patients under 40 years of age and repeat colonoscopies were excluded, leaving 3151 patients (mean age: 63 years; 48% male). Demographics including ethnicity and medical background were retrieved from the electronic patient record system and findings correlated with the prevalence of other 'Western' diseases in the cohort. RESULTS: Six hundred and thirty out of 3151 (20%) colonoscopies were performed on Bangladeshis. The prevalence of colonic diverticulosis was significantly lower in Bangladeshis (17/630: 2.7%) than Caucasians (673/1869: 36%), Indians/Pakistanis (16/161: 9.9%), Oriental (15/44: 34%) and Black (90/369: 24.4%) patient groups (χ(2) p < 0.0001 for all comparisons). The prevalence of classical sigmoid diverticulosis in the Bangladeshi cohort was only 1.0%, despite significantly more Bangladeshi patients undergoing colonoscopy for abdominal pain (p < 0.0001, χ(2)) and diarrhoea (p < 0.0034, χ(2)). There was also a significantly greater incidence of type 2 diabetes mellitus and ischaemic heart disease (p < 0.0001, χ(2)) in Bangladeshi patients. CONCLUSIONS: There is a negligible prevalence of colonic diverticulosis in the Bangladeshi population of London who undergo colonoscopy. This is in spite of a high incidence of type 2 diabetes and ischaemic heart disease. The effect of diet and genetics on the prevalence of colonic diverticulosis in Bangladeshis is not known and merits further investigation.
