Qualitative, quantitative, and mixed-methods systematic reviews were identified, without language or date limits.

Another 10 facilitators were new to this update. There were 16 barriers, most commonly: perceived risk, practical difficulties, and distrust of researchers. Many barriers applied to specific designs, particularly randomised trials. Factors that were barriers or facilitators include the influence of others and information quality.

After total mesorectal excision (TME) and coloanal anastomosis, participants face high risks of anastomotic leakage and infection, often requiring a protective ileostomy. However, ileostomies themselves lead to significant complications, such as dehydration and chronic renal failure, and many participants cannot have their stomas reversed as planned. The Turnbull-Cutait procedure, involving delayed transanal pull-through rectal resection, has emerged as a safer alternative, reducing leakage complications and avoiding the need for a protective stoma. Recent studies support its use in challenging rectal cases, showing comparable or better outcomes than standard techniques. Despite these promising results, limited data exists on its application to intersphincteric resection (ISR) or intersphincteric dissection (ISD), which itself has higher complication rates. Therefore, further research is needed to evaluate this Turnbull-Cutait anastomosis procedure (delayed transanal pull-through) in ISR, comparing its complications, oncological outcomes, and functional results to those of traditional methods (direct anastomosis). This study is a prospective, multicenter, 1:1, non-inferiority, randomized controlled trial with 110 participants, divided into two groups: the staged Turnbull-Cutait pull-through anastomosis group (n = 55) and the direct anastomosis group (n = 55). The control group will undergo ISR with traditional anastomosis plus protective ileostomy, while the experimental group will receive the transanal pull-through and delayed anastomosis without ileostomy. The primary outcome is the 30-day overall postoperative complication rate, including anastomotic leakage, infection, and other complications. Secondary outcomes include long-term complications, total surgery time, anorectal function (measured by LARS and Wexner scores), urinary and sexual function, quality of life (EORTC QLQ-CR29 and FIQL), and 3-year disease-free survival (DFS) and overall survival (OS).&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Discussion: &lt;/strong&gt;Currently, there is a lack of systematic studies exploring the use of delayed pull-through anastomosis in intersphincteric resection (ISR) procedures. Existing research on this technique in low rectal cancer is limited to small, single-center, retrospective studies with low levels of evidence. Therefore, a multicenter, prospective, randomized controlled trial is needed to determine whether delayed pull-through anastomosis can serve as a viable alternative to ISR-coloanal anastomosis, offering comparable or lower rates of postoperative complications, as well as similar oncological outcomes and defecatory function.

Despite the well-documented benefits, many individuals with (pre)diabetes remain insufficiently active. General practitioners (GP) provide an accessible platform for delivering interventions; however, integrating PA interventions into routine care is hindered by resource constraints.</p><p><strong>Objectives: </strong>The ENERGISED trial aims to address these barriers through an innovative GP-initiated mHealth intervention combining wearable technology and just-in-time adaptive interventions.</p><p><strong>Methods: </strong>The ENERGISED trial is a pragmatic, 12-month, multicentre, randomised controlled trial, assessing a GP-initiated mHealth intervention to increase PA and reduce sedentary behaviour in patients with type 2 diabetes and prediabetes. The primary outcome is daily step count, assessed via wrist-worn accelerometry. The primary analysis follows the intention-to-treat principle, using mixed models for repeated measures. Missing data will be handled under the missing-at-random assumption, with sensitivity analyses exploring robustness through reference-based multiple imputation. The trial incorporates the estimand framework to provide transparent and structured treatment effect estimation.</p><p><strong>Discussion: </strong>This statistical analysis plan outlines a robust approach to addressing participant non-adherence, protocol violations, and missing data. By adopting the estimand framework and pre-specified sensitivity analyses, the plan ensures methodological rigour while enhancing the interpretability and applicability of results.</p><p><strong>Conclusions: </strong>The ENERGISED trial leverages innovative mHealth strategies within primary care to promote PA in individuals with (pre)diabetes. The pre-specified statistical framework provides a comprehensive guide for analysing trial data and contributes to advancing best practices in behavioural intervention trials for public health.</p><p><strong>Trial registration: </strong>ClinicalTrials.gov NCT05351359 .
