Suboptimal feeding practices in children under five remain a critical concern, particularly in low- and middle-income countries. Integrated Supplementary Feeding programmes (SFPs) combined with Social and Behaviour Change Communication (SBCC) interventions have shown potential, yet global evidence on their design and effectiveness remains scattered across diverse settings and varies widely in scope and quality. This review aims to map global evidence on integrated SFP and SBCC interventions for children aged 6–59 months, assessing their impact on anthropometric, biochemical, nutritional, health, developmental, functional, microbiological and infant and young child feeding (IYCF) outcomes, and to identify contextual factors, evidence gaps and successful strategies. The review will also aim to document cost effectiveness and economic outcomes of this integrated intervention.

The review will follow Joanna Briggs Institute (JBI) methodology, applying the Population–Concept–Context framework and the review title has been registered in Open Science Framework (OSF) (https://doi.org/10.17605/OSF.IO/ZJ5BG). Eligible studies published between 2000 and 2025 will include community-based interventions for children under five that combine SFP and SBCC. The review will focus on SFP interventions delivered through community-based or public health platforms, including but not limited to take home ration, hot cooked meal, micronutrient powders, coupled with SBCC modalities such as home visits, mobile health and mass media campaigns. Comprehensive searches will be conducted in MEDLINE (PubMed), Cochrane CENTRAL, Google Scholar and organisational websites. Two independent reviewers will screen, extract and appraise studies using Covidence and JBI tools. Data will be analysed using descriptive statistics to summarise study characteristics, intervention types and reported outcomes, helping understand patterns across time and settings. Qualitative findings will be synthesised through descriptive content analysis involving coding and theme development. Expected outcomes include a range of study designs from different settings across the globe, covering diverse delivery models of integrated SFP and SBCC with reported outcomes including dietary indicators, anthropometry, nutritional biomarkers, caregiver practices and cost-effectiveness.

This review is part of a larger cluster randomised controlled trial (NECCTAR) which has received ethical approval from the independent institutional ethics committee of all the participating institutes. The current review will involve only publicly available literature and does not have a separate institutional ethics committee approval. Findings will be disseminated through academic conferences and publications in peer-reviewed journals.

Poor cardiopulmonary fitness is an important risk factor for postoperative complications, yet a feasible, objective and prognostically accurate method to assess preoperative fitness has not been established. The 6 min walk test (6MWT) is a simple, inexpensive and widely applicable measure that shows promise for predicting postoperative risk. However, robust data are lacking on whether the 6MWT accurately predicts complications, provides incremental prognostic value beyond routinely collected clinical factors or outperforms simpler alternatives such as questionnaires, cardiac biomarkers or grip strength testing. The Functional Assessment for Surgery by a Timed Walk (FAST Walk) study is designed to address these knowledge gaps by evaluating whether the 6MWT improves prediction of key postoperative outcomes compared with clinical factors and simpler measures of fitness.

The FAST Walk study is an international multicentre prospective cohort study of 1672 adults (≥40 years) undergoing major elective non-cardiac surgery at centres in Canada, Hong Kong, Australia, Spain and the Netherlands. Participants complete a preoperative 6MWT and baseline assessments of comorbidities, self-reported cardiopulmonary fitness (MET: Re-evaluation for Perioperative Cardiac Risk questionnaire), biomarkers (N-terminal pro-B-type natriuretic peptide) and grip strength. The primary outcome is 30-day death or major postoperative complication, defined as Clavien-Dindo grade II or higher. Secondary outcomes are (1) death or new significant disability at 90 days after surgery and (2) days alive and out of hospital at 30 days after surgery. Disability is measured using the short-form WHO Disability Assessment Schedule 2.0 instrument. Multivariable regression models and complementary metrics of prediction performance will be used to determine whether 6MWT distance adds prognostic value beyond routinely collected clinical factors and simpler measures of fitness.

The FAST Walk study has received research ethics board approval at all participating sites. Recruitment commenced in June 2024, with completion of participant follow-up expected in 2026. Findings will be disseminated through peer-reviewed publications and conference presentations, with the primary results anticipated in 2027.

Inhaled anaesthetics can be used in mechanically ventilated critically ill patients to provide sedation. This approach to sedation potentially improves patient and health system outcomes, but further supportive evidence is needed. The objective of the SAVE-ICU clinical trial is to compare the effectiveness of inhaled versus intravenous sedation in ventilated adults with acute hypoxaemic respiratory failure.

SAVE-ICU is a multicentre, open-label, pragmatic, randomised controlled trial conducted in 15 intensive care units (ICUs) in Canada and the USA. Eligible patients include mechanically ventilated and sedated adults with acute hypoxemic respiratory failure from COVID-19 or non-COVID causes with PaO₂/F_IO₂ ratio 12 hour). A hierarchy of outcomes was identified at the time of trial design, as the trial was launched during the COVID-19 pandemic when study drug shortages, staffing challenges and healthcare system pressures were prevalent and there was a requirement for rapid evidence generation and implementation on this topic. The primary outcome and highest in the hierarchy is hospital mortality (requiring 758 participants). Secondary and lower hierarchical outcomes are ventilator-free days at day 30 (200 patients), quality of life at 3 months (144 participants) and ICU-free days at day 30 (128 participants). Additional secondary outcomes include median daily oxygenation at day 3 (PaO₂/F_IO₂ ratio), need for adjunctive acute respiratory distress syndrome therapies (prone positioning, inhaled nitric oxide, paralysis with a neuromuscular blocking agent and extracorporeal membrane oxygenation) during ICU stay, days alive and free from delirium and coma at day 14, hospital-free days at day 60 and disability score at 3 months and 12 months after enrolment.

The protocol was approved by all hospital ethics committees and by Health Canada. Informed consent will be obtained from substitute decision makers or deferred consent (as permitted by site ethics board). Trial findings will be shared at the end of the study using peer-review publications, conference presentations and social media as part of the trial knowledge translation plan.
