Cancer is the leading cause of death and morbidity among children and adolescents worldwide. Functionality-based interventions are relevant among children and adolescents with an oncological diagnosis, whence studies summarising evidence on this topic are needed. This systematic review will summarise evidence on the effect of interventions to improve functionality indicators among paediatric patients diagnosed with cancer.

This protocol will follow Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA)-Protocols reporting guidelines. The systematic review will be conducted according to the Cochrane Handbook and PRISMA 2020. Studies will be searched in MEDLINE (PubMed), Embase, Web of Science, CENTRAL, LILACS and PEDro. Additional searches will include Google Scholar, reference lists of included studies, relevant reviews and trial registries. Studies will be included if they implement a functionality-based intervention. They must evaluate effects among paediatric patients with an oncological diagnosis. Secondary outcomes will include health-related quality of life. There will be no limits to language or year of publication, and articles published in peer-reviewed journals will be accepted. Only randomised controlled trials will be included. Risk of bias will be assessed using the Cochrane Risk of Bias Tool 2. Two independent reviewers will select studies, extract data and assess risk of bias. A narrative synthesis and meta-analysis will be conducted if studies are clinically and methodologically homogeneous. Statistical heterogeneity will be assessed using Higgins’ inconsistency test (I^²). Meta-analysis may estimate combined effects using random-effects and the inverse variance method. The R statistical software will be used. The certainty of evidence will be evaluated for each outcome using the Grading of Recommendations Assessment, Development and Evaluation system.

This study used data from previously published studies, thus waiving submission to an Ethics Committee. Scientific dissemination strategies will include publication in peer-reviewed journals, conference presentations and workshops for the public.

Healthcare logistics involves the coordination of resources, services and infrastructure to ensure timely and efficient care delivery. Process mining offers data-driven insights into logistical workflows such as patient transport, inventory management and scheduling. This systematic review aims to synthesise evidence on the application of process mining in healthcare logistics, focusing on its impact on operational efficiency, resource utilisation and service delivery.

A systematic search will be conducted in MEDLINE, Embase, Google Scholar, Web of Science and ABI/Inform for studies published from 1999 onward. Eligible studies will include observational studies, case reports, conference papers and meta-analyses focusing on process mining applications to logistical processes in healthcare settings. Studies screening, data extraction and methodological quality assessment will be conducted using the Mixed Methods Appraisal Tool. Data will be extracted on key dimensions and performance indicators and will be presented in a structured format. A narrative synthesis will be conducted, and findings will be categorised and thematically analysed where appropriate. Primary outcomes include improvements in logistical efficiency, traceability, resource utilisation and sustainability. Secondary outcomes include implementation challenges, data integration issues and limitations in applying process mining techniques to logistical workflows.

The results of the systematic review will be disseminated via publication in a peer-reviewed journal and presented at a relevant conference. The data we will use do not include individual patient data, so ethical approval is not required.

Sickle cell disease (SCD) is due to the mutation of haemoglobin (Hb), from HbA to HbS and characterised by recurrent vaso-occlusive crises (VOC), which can progress to acute chest syndrome (ACS), a leading cause of death in adults with SCD. Hypoxia is a key modifiable factor in the polymerisation of HbS and the pathogenesis of VOC. High-flow nasal oxygen (HFNO) delivers humidified gas at high oxygen concentrations and flow rates: the former may reverse sickling (metabolic effect) to accelerate VOC resolution and prevent ACS, while the latter may reduce the risk of ACS by mitigating hypercapnia and generating positive airway pressure that limits hypoventilation and atelectasis (pulmonary effect). The study hypothesises that HFNO is a safe and effective strategy for treating VOC and preventing secondary ACS, and will assess this using a multi-arm multi-stage (MAMS) trial design.

This is a prospective, multicentre, randomised, open-label controlled trial following an MAMS design with three phases and four arms: one control (low-flow oxygen) and three HFNO intervention arms with varying fraction of inspired oxygen levels (low, intermediate, high). The pilot stage will assess safety and feasibility, using the rate of cardiac and neurological events as the primary endpoint. In the activity stage, arms demonstrating acceptable safety will be compared for efficacy based on the rate of VOC resolution without complications by day 5, allowing selection of the most promising arm. The final efficacy stage will compare the selected HFNO strategy to control, with prevention of secondary ACS by day 14 as the primary endpoint. The study aims to enrol up to 350 VOC episodes in total.

The study has been granted ethical approval (CPP SUD MEDITERRANEE IV). Following the provision of informed consent, patients will be included in the study. The results will be submitted for publication in peer-reviewed journals.
