Risultati per: Infezione da Helicobacter pylori: review

Introduction
Haemostasis, a process involving platelet activation, platelet aggregation and coagulation, poses intricate clinical challenges for clinicians. There remains significant national variability in thromboprophylaxis protocols, which are used in 77–82% of surgical cases in Australia. There is also increasing concern focused on the development of antiplatelet resistance. Given an apparent lack of standardised approaches to haemostasis, these decisions frequently require clinician discretion and can result in suboptimal outcomes. To optimise patient management, all available therapeutic agents should be considered. Current standards may need to be revised accordingly.
Dextrans are polysaccharides with perioperative significance in haemostasis. Although the proposed mechanisms of dextran action are multifactorial, these agents may have a significant impact in cases of trauma, reconstructive surgery, transplantation and vascular surgery. However, a suspected deficit in the quality of the literature, and therefore clinical standardisation, raises concerns for optimal incorporation into practice.
Accordingly, we plan to examine both peer-reviewed articles and ‘grey’ literature that considers the indications, efficacy and complications associated with the clinical use of dextrans to promote haemostasis. The primary objective of this scoping review will be to analyse and map the existing literature on the use of dextrans in both operative and non-operative settings and provide insight that will bridge the current knowledge gap and guide future research initiatives.

Methods and analysis
The study and literature search will be performed in accordance with recommendations adapted for scoping reviews in alignment with Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Scoping Reviews standards. A thorough and systematic investigation will be undertaken across several electronic databases, including EMBASE, the Cochrane Library and MEDLINE; additional studies will be accessed and examined by reference tracking. All relevant research published before 11 March 2024 will be reviewed for appropriateness of inclusion. Two researchers will perform data screening and extraction of relevant information. Study observations will be presented in a descriptive manner using a mixed methods and narrative approach.

Ethics and dissemination
Ethics approval was not required for this study. The results will be disseminated through publication in open-access peer-reviewed journals, established professional networks and conference presentations.

Introduction
People with intellectual disability experience lower levels of employment than those with other disabilities and those without disability, and typically require support services to access and maintain employment. Reviews on employment support often focus on the perspectives of providers and employers, meaning that, thus far, the perspectives of people with intellectual disability and their family members have not been collated and synthesised. This review will address this evidence gap.

Methods and analysis
Six databases (CINAHL, EconLit, EMBASE, Medline Complete, PsychINFO, Web of Science) will be comprehensively searched for the last 20 years to identify English-language, peer-reviewed publications including primary qualitative data. Search results will be independently screened by three reviewers (CP, NM, SF). Backwards and forwards citation tracing will be used to identify any additional literature not found by the searches. A narrative summary of the included studies will be provided. Study characteristics such as research focus, design, setting and findings will be independently extracted by one reviewer, checked by a second. Methodological quality will be independently evaluated by two reviewers using the Critical Appraisal Skills Programme Qualitative Studies Checklist. Findings from the studies will be collated using thematic synthesis and a realist approach. Any disagreement during the review process will be resolved by a third reviewer.

Ethics and dissemination
Ethics approval is not required to conduct the planned systematic review of peer-reviewed, published articles because the research does not involve human participants. Findings will be published in a peer-reviewed journal, presented at leading disability conferences and disseminated via website postings and social media channels.

Background
Electroconvulsive therapy (ECT) is an established treatment for depression and mania, with its therapeutic effect deriving from the induced seizure rather than the electrical stimulus itself. Anaesthetic agents are routinely used to reduce procedural discomfort, requiring assisted ventilation. However, these agents may raise the seizure threshold, necessitating higher stimulus doses and potentially increasing adverse effects. Although various strategies have been explored, pre-ECT hyperventilation—despite its known ability to lower the seizure threshold—remains insufficiently investigated. This review aims to examine the various ventilation approaches employed during anaesthesia for ECT, assess how hyperventilation has been applied to augment ECT, explore their impact on clinical outcomes and identify the outcome parameters most frequently investigated in ECT studies.

Methods
The reporting of the scoping review will adhere to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews guidelines. A comprehensive literature search will be conducted in Medline, EMBASE, Scopus and PsycINFO. Grey literature, along with national and international guidelines, will also be included. Studies investigating any form of ventilation during anaesthesia for ECT will be included. An information specialist and a medical librarian will support the development and refinement of the search strategy. Two reviewers will independently screen eligible studies and perform data extraction according to predefined headings. Disagreements will be resolved by a third reviewer. Data will be organised under the following headings: details of the included studies, ventilation strategies investigated, outcome measures studied. Results will be presented narratively and in table form and discussed in relation to the relevant literature.

Ethics and dissemination
Ethical approval is not necessary, as the review synthesises evidence from the existing literature. The results will be disseminated through publication in a peer-reviewed journal and presentation at relevant academic conferences. Findings will also be shared with ECT clinicians to support clinical awareness and inform practice.

Objectives
The Idea, Development, Evaluation, Assessment and Long-term follow-up (IDEAL) framework was designed to improve the quality of surgical research and evaluation of surgical innovation. It has become a widely cited tool for evaluating innovative devices and procedures, yet challenges remain concerning the definition and reporting of incremental innovative modifications, hindering evolution and evaluation of innovations and potentially risking patient safety. This systematic review examined IDEAL studies to identify such modifications and establish recent practices around modification reporting to inform the development of future guidance to facilitate safe, transparent and efficient surgical innovation.

Design
Systematic review and thematic synthesis of studies reporting surgical innovation.

Data sources
Web of Science and Scopus were searched in July 2023 using citation tools to identify studies following the IDEAL framework (citing any of 13 key IDEAL/IDEAL framework publications and guideline papers).

Eligibility criteria
Primary research studies of any design that involved invasive innovative devices or procedures.

Data extraction and synthesis
Study characteristics and verbatim text for all reported modifications, including contextual information, were extracted. Data were analysed and synthesised using thematic synthesis.

Results
Of 1071 records screened, 104 studies published between 2011–2023 were included (n=87 (83.6%) study reports; n=17 (16.3%) protocols). 425 modifications were reported in 76 (73.1%) studies, including modifications to procedures (n=283, 66.6%), devices (n=94, 22.1%) and patient selection (n=48, 11.3%). Procedure/device modifications included technical, non-technical and cessation (conversion to other procedures or abandonment). Modifications were most often reported within IDEAL stage 2a (n=30/44, 68.2%), whereas there was considerable variation across other stages, such as stage 0 (n=2/3, 66%) and stage 2b (n=4/12, 33.3%).

Conclusion
Reporting modifications is imperative for evaluating surgical innovation. However, this review found inconsistent approaches to reporting and describing modifications. Findings will inform the development of a checklist for reporting modifications that aims to complement the IDEAL framework and further promote shared learning, avoiding the repetition of harmful/ineffective modifications and enhancing patient safety.

Introduction
Sleep disturbance is prevalent in pregnancy and can result in significant adverse outcomes for women and their infants. Numerous clinical trials of various nonpharmacotherapies for preventing or treating sleep disturbances have been conducted previously; however, previous systematic reviews with direct comparisons have failed to demonstrate the best options for different kinds of treatments. This systematic review and network meta-analysis (NMA) aims to explore the comparative efficacy and acceptability of nonpharmacological interventions for sleep disturbances in pregnancy and to assist clinical decision-making through ranking interventions concerning critical clinical outcomes.

Methods and analysis
We will follow the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) statement. Two reviewers will systematically search five major bibliographic databases (PubMed, Embase, Cochrane Library, Web of Science and Cumulative Index to Nursing and Allied Health Literature) and registries for published and unpublished randomised controlled trials (RCTs) of any nonpharmacological interventions for sleep disturbances from inception to 24 June 2025. To ensure the search is up to date, we will also perform an updated search up to the time of final analysis submission. Primary outcomes will consider efficacy (the overall mean change of any predefined sleep disturbances, including sleep quality, sleep duration and sleep-specific symptoms) and acceptability (all-cause discontinuation). The risk of bias of each included RCT will be assessed using the Cochrane Risk of Bias 2.0 Tool (RoB2). Traditional pairwise meta-analyses and NMAs will be performed to compare the efficacy and acceptability of different nonpharmacological interventions. Surface under the cumulative ranking curve for the outcomes of interest will be used to rank the competing interventions. The Grading of Recommendations, Assessment, Development and Evaluation system will be used to assess the quality of evidence associated with the main results.

Ethics and dissemination
This review is a secondary analysis of published data and, therefore, does not require ethical approval. The results will be disseminated in a peer-reviewed journal.

Introduction
Stress is omnipresent in our everyday lives and a key risk factor for our physical and mental health. Yet little is known about the impact of geographic life environments, linked to our daily activities and mobility patterns, on our momentary and daily stress levels.
We propose this review to gather evidence on the spatio-temporal determinants of momentary or daily stress in studies using ecological momentary assessment (EMA) or experience sampling methods (ESM) in addition to global positioning systems (GPS) tracking. We will focus on the spatio-temporal definition and modelling of environmental exposures accounting for participant daily activities and mobility patterns and their association with stress.

Methods and analysis
This scoping review will follow the Preferred Reporting Items for Systematic Reviews and Meta-Analyses framework for scoping reviews (2018). We will search the PubMed/Medline, Web of Science, PsycInfo and Scopus databases. We will include papers using EMA or ESM and GPS measuring chronic, daily or momentary stress as an outcome; these methods are also referred to as geographically-explicit ecological momentary assessment.
Articles published from January 2000–June 2025 will be screened. Two independent reviewers will screen titles and abstracts to agree on the inclusion of articles. No geographical or population limitation will be imposed.

Ethics and dissemination
This study is a scoping review based on previously published and publicly available literature. It does not involve the collection of primary data, human participants, or the processing of personal or sensitive information. Therefore, ethical approval is not required in accordance with institutional and international research ethics guidelines. The results will be submitted in peer-reviewed journals and presented at international conferences.

Objectives
Low-level viremia (LLV) is a risk factor affecting the prognosis of patients with chronic hepatitis B (CHB). The objective of this study was to systematically assess the prevalence of LLV, thereby providing robust evidence-based medical insights into effective clinical interventions and preventative measures against LLV.

Design
Systematic review and meta-analysis.

Data sources
A comprehensive literature search was conducted across various databases, including China National Knowledge Infrastructure, Wanfang Data (Wanfang), China Science And Technology Journal Database (VIP-CSTJ), China Biology Medicine disc (CBMdisc), PubMed, Embase, Web of Science and the Cochrane Library, spanning from the inception of these databases up to 5 January 2024.

Eligibility criteria
The research type included either a cross-sectional study or a cohort study focusing on the Chinese population, with the outcome being LLV. The languages were limited to both Chinese and English. Studies with any of the following were excluded: subjects with other comorbidities, original articles inaccessible or data unavailable, and duplicate publications.

Data extraction and synthesis
Literature management used EndNote X9.1, and an information extraction table was created using Microsoft Excel to record research information, including first author, year of publication and study type. The prevalence of LLV was assessed via meta-analysis. Meta-analyses were conducted in RStudio using the ‘metaprop ()’ function. Subgroup analysis and sensitivity analysis were used to identify sources of heterogeneity, and funnel plots and AS-Thompson tests were employed to evaluate publication bias.

Results
18 studies, encompassing a total sample of 9773 patients, were included in the analysis. Of these, 3336 patients were identified with LLV. The meta-analysis revealed that the prevalence of LLV among treated CHB patients stands at 33.6% (95% CI 30.2 to 37.0). The antigen status, antiviral treatment regimen (type of drugs and nucleos(t)ide analogues (NAs)), treatment duration, medication adherence and baseline hepatitis B virus DNA levels all affected the prevalence of LLV. Sensitivity analysis further corroborated the stability of these meta-analysis findings. The funnel plot and AS-Thompson test indicated no significant publication bias (t = –0.01, p=0.995).

Conclusions
The prevalence of LLV among CHB patients was established at 33.7% (95% CI 29.8% to 37.6%). Thus, it is imperative for clinical decision-makers to consider the various influencing factors of LLV when formulating treatment plans in order to mitigate any potential adverse outcomes.

Objectives
This scoping review aims to map existing evidence on knowledge, attitudes and practices (KAP) and barriers to preconception care in low- and middle-income countries. The primary objective is to identify key gaps and research priorities to guide future efforts to improve maternal and child health.

Design
This review followed Arksey and O’Malley’s scoping review framework, with a comprehensive search across Medline, EMBASE, CINAHL and Scopus from inception to May 2025. Eligible studies included original research on preconception care (PCC), KAP in low- and middle-income countries (LMICs) without date restrictions. Two independent reviewers conducted screening in Covidence. Findings were presented in graphical, tabular and narrative formats, adhering to the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols Extension for Scoping Reviews (PRISMA-ScR) standard.

Setting
The review focused on PCC studies conducted in LMICs across various healthcare settings, emphasising primary and secondary levels of care. The geographical scope was global but limited to LMICs as defined by World Bank criteria.

Result
A total of 62 studies were included in the review. Of these, 42 employed quantitative methods, 18 used qualitative approaches and 2 used a mixed-methods design. Regarding focus areas, 25 studies assessed knowledge, 14 assessed practices, 12 studies assessed KAP comprehensively and 10 assessed attitudes. Participants were mainly women of reproductive age (44 studies), with only five studies including men. Among healthcare providers, KAP varied, with midwives being the most frequently studied group. Stakeholders such as policymakers were notably under-represented. Identified barriers included limited training, cultural beliefs and inadequate policies. Facilitators highlighted were targeted education, spousal support and policy advocacy, emphasising the need for gender-sensitive and systemic interventions.

Conclusion
LMICs face complex challenges in utilising PCC, influenced by socioeconomic, cultural, and healthcare system factors. To address these challenges, nuanced approaches incorporating intersectional perspectives and practical qualitative methodologies are essential for improving couples’ and child health outcomes.

Trial registration number
The study protocol was registered in the Open Science Framework (OSF) on December 23, 2022, with DOI: 10.17605/OSF.IO/H3MK6.

Objectives
This systematic review investigated available evidence on the stand-alone and incremental predictive performance of ophthalmic artery Doppler (OAD) for pre-eclampsia.

Design
Systematic review.

Data sources
We conducted a literature search from PubMed (Medline), the Cochrane CENTRAL, EMBASE and Scopus from inception to 8 April 2025.

Eligibility criteria
Studies eligible for inclusion were prospective or retrospective cohort studies, case-control studies or randomised controlled trials that reported on the predictive performance of OAD for pre-eclampsia in singleton pregnancies; and conducted in either high-income country (HIC) or low- and middle-income country (LMIC).

Data extraction and synthesis
Two reviewers independently screened and assessed articles for inclusion. One reviewer then extracted data using a standardised data extraction sheet, and any uncertainties were discussed with a second reviewer. The Prediction model Risk of Bias Assessment Tool was used for quality and risk of bias assessment. Findings were summarised and reported according to the Preferred Reporting Items for Systematic Review and Meta-Analyses statement and synthesised qualitatively.

Results
We identified and included 11 observational studies (3 from HIC and 8 from LMICs) with a total of 12 150 singleton pregnancies, of which 517 (4.3%) were complicated by pre-eclampsia at end of follow-up. The included studies were of varied quality, with three at low risk of bias, four at unclear risk and four at high risk. No interventional study was identified. Three studies (27.3%) recruited high-risk pregnancies (defined according to the American College of Obstetricians and Gynecologists (ACOG) criteria as one or more of the following: chronic hypertension, personal or family history of pre-eclampsia, early (≤18 years) or late (≥40 years) first pregnancy, primipaternity, chronic kidney disease, increased body mass index >30 kg/m2, presence of diabetes mellitus prior to pregnancy, autoimmune disease and thrombophilia), while eight studies (72.7%) recruited undetermined risk pregnancies. Stand-alone performance of OAD (interpreted by area under the receiver operating curve at 95% CI) showed that in the first trimester, the peak systolic velocity (PSV) ratio demonstrated very good predictive ability (0.97, 95% CI 0.92 to 1.0) (n=1 study), and the second PSV (PSV2) demonstrated very good predictive ability (0.91, 95% CI 0.82 to 0.99) (n=1 study). Also, PSV2 demonstrated fair predictive ability (0.61, 95% CI 0.42 to 0.79; and 0.53, 95% CI 0.40 to 0.66) for early and late pre-eclampsia, respectively (n=1 study). In the second trimester, the PSV ratio demonstrated very good predictive ability (0.88, 95% CI 0.84 to 0.91) (n=1 study), and PSV2 demonstrated good predictive ability (0.73, 95% CI 0.66 to 0.81; and 0.76, 95% CI 0.71 to 0.81) for pre-eclampsia (n=2 studies). In the third trimester, the PSV ratio demonstrated good predictive ability (0.82, 95% CI 0.73 to 0.89; and 0.77, 95% CI 0.71 to 0.82) for preterm and term pre-eclampsia, respectively (n=1 study). Also, PSV2 demonstrated good predictive ability 0.70 (0.57 to 0.84) (n=1 study).
Subsequently, in the second trimester, PSV ratio demonstrated better incremental predictive performance than uterine artery pulsatility index for preterm pre-eclampsia, when added to maternal factors and mean arterial pressure (MAP) (56.1%–80.2% vs 56.1%–74.8% detection rate (DR) at 10% FPR) (n=1 study). Also in the third trimester, adding PSV ratio to maternal factors and MAP was superior to soluble fms-like tyrosine kinase-1/placental growth factor ratio in predicting pre-eclampsia at

Conducting clinical research in response to infectious disease outbreaks presents unique challenges. In a previous review, we identified a range of political, economic, administrative, regulatory, logistical, ethical and social (PEARLES) challenges and proposed solutions to effective implementation of outbreak research responses. Following the COVID-19 pandemic, we conducted an update to explore if solutions recommended had been implemented, or new challenges identified. We searched seven databases (Ovid MEDLINE, Global Health, Embase, and PsycINFO, Scopus, Epistemonikos, Google Scholar) and grey literature from 01/06/2018 to 28/09/2023 for studies presenting PEARLES challenges/solutions to epi/pandemic research responses.

Introduction
interRAI is a global collaboration of clinicians, researchers and policy-makers who have developed a suite of assessment tools to assess the health status and care needs of older adults in various settings (ie, home, long-term care, etc). We aim to determine how interRAI tools have been used as an intervention and to evaluate intervention efficacy in older adults (65+) across diverse healthcare settings. Importantly, given the deployment of interRAI primarily in high-income countries, we anticipate that the findings may have minimal relevance to low- and middle-income nations, where there is an immediate and urgent need for equity in geriatric assessment.

Methods and analysis
To be included, all studies must satisfy our inclusion criteria, outlined by the population (ie, older adults and/or individuals providing some element of care to older adults), intervention (ie, randomised or non-randomised), comparator (ie, with or without one) and outcome (ie, how the interRAI formed the basis of a study intervention). Our search strategy is based on previous reviews of interRAI tools, our research and clinical experience, and the expertise of a specialised librarian. In addition to PubMed, we will conduct our search without date or language restrictions in Scopus, Embase,Cumulative Index to Nursing and Allied Health Literature (CINAHL), Academic Search Premier and PsycInfo. Study screening will employ a team-based approach, with Kappa statistics >0.8 indicating ‘substantial’ agreement and an acceptable threshold. Data extraction will capture the study ID and design, as well as sample characteristics and outcomes. Reporting will adhere to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews, with findings presented graphically and narratively.

Ethics and dissemination
Ethics approval is not required. Our knowledge dissemination strategies include traditional research avenues (ie, manuscript publications). We will also create an infographic to disperse widely and leverage existing partnerships to provide community presentations.

Introduction
Non-pharmacological interventions, including musculoskeletal manipulations (MMs), have been proven effective for musculoskeletal disorders.

Objectives
To evaluate if MMs, including osteopathic manipulation and chiropractic care, are effective to improve quality of life, pain intensity and function in older adults with musculoskeletal disorders.

Design
Systematic review.

Data sources
A systematic search was conducted on MEDLINE/PubMed, EMBASE, Scopus, Web of Science, CINAHL, Cochrane Library, from database inception up to 2 January 2025.

Eligibility criteria
Randomised controlled trials, controlled non-randomised trials and open label trials evaluating the efficacy and safety of MM such as osteopathic manipulation, chiropractic manipulation, myofascial release, craniosacral therapy, as monotherapy or adjunctive therapies in older people (age ≥65 years) with musculoskeletal disorders. The main outcomes included pain intensity, functionality and quality of life. Additionally, other related outcomes were considered, such as medical use duration, mood, mobility, motion, strength and endurance. Finally, we considered any adverse events.

Data extraction and synthesis
Selection and data extraction were performed independently by two authors. The effect estimates for each study were performed using Review Manager V.5.14. Continuous outcomes were analysed using the mean difference (95% CI). The methodological quality of the included studies was assessed using the Cochrane Risk of Bias tool 2 (RoB 2). No meta-analysis was performed.

Results
Five parallel randomised controlled trials were included, with a total sample size of 676 participants (41.6% women with a mean age of 77.3 years): 34 with chronic pain, 265 with neck pain and 377 with low back pain. MMs were not effective in patients with chronic pain, neither in pain intensity nor in functionality. For neck pain, considering the main outcomes, only in one of the two studies was there a statistically significant improvement in neck pain intensity only at week 12 for spinal manipulative treatment (SMT)+home exercise (HE) compared with HE alone (ES=–0.90 (95% CI –1.46 to –0.34); p=0.002). For low back pain, SMT+HE showed a statistically significant reduction in pain at 12 weeks compared with HE (ES=–0.79 (95% CI –1.39 to –0.19) p=0.010. For neck pain and low back pain, no statistically significant improvement in functional status and quality of life was observed with MM compared with any control group. RoB 2 showed a high risk of bias in three studies and some concerns in the others. At the domain level, the lowest risk was observed in the randomisation process (80% with some concerns). All five studies reported adverse events, none of which were serious.

Conclusions
This review provides limited and inconclusive evidence about MM to improve quality of life, pain management and functional status in older adults with musculoskeletal disorders. However, MM appears to be generally safe and well-tolerated.

Background
Health disparities persist, posing significant health, social and economic challenges. Digital health technologies (DHTs) present a promising opportunity to address these inequities and advance health equity. Despite this potential, a comprehensive and structured overview of existing frameworks and guidelines on advancing health equity and a clear understanding of the potential of DHTs in their implementation to systematically close the healthcare gap is yet to be done.

Objective
To this end, our objectives are twofold: first, to identify frameworks and guidelines that promote health equity and second, to pinpoint the role of DHTs as an avenue for their implementation. We conducted a scoping review informed by Arksey and O’Malley’s five-stage framework, methodological guidelines by the Joanna Briggs Institute and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews.

Sources of evidence
A comprehensive search was conducted across seven databases on 6 December 2023: PubMed, EMBASE, Cochrane, PsycINFO, Scopus, Web of Science and WISO.

Eligibility criteria
We included primary and secondary studies published in English between 2010 and 2023 focusing on advancing health equity for priority populations.

Charting methods
For the analysis, we applied multistaged coding approaches to answer our twofold objective.

Results
The search identified 6419 studies, of which 38 met our final inclusion criteria and were included in this review. We extracted 559 recommendations on advancing health equity and synthesised these into 82 distinct recommendations across five levels of initiative and 19 areas of initiative. Thereby, 24% of the included studies explicitly mentioned the use of (digital) technology with 10 impact opportunities on advancing health equity.

Conclusion
Our synthesis offers key insights into the advancement of health equity across different levels of initiative and the role of DHTs in their implementation. This offers practitioners and researchers alike a comprehensive overview to make health equity advancement more tangible and actionable.

Introduction
Dental neglect in children and adolescents is a form of child maltreatment and can be an indicator of other forms of maltreatment. Early identification of dental neglect is essential to initiate preventive interventions and connect families to appropriate health and social services to avoid further harm and to reduce negative impacts on child development and well-being. Articles that systematically synthesise and compare models for early detection, intersectoral cooperation and care for dental neglect have not been published yet. This scoping review aims to map the evidence on strategies for the identification and prevention of dental neglect in children and adolescents.

Methods and analysis
The study is designed as a scoping review. Based on the Population, Concept and Context (PCC) scheme, the databases PubMed, PsycInfo and Scopus are searched for publications before July 2023. Publications in all languages will be considered in case an abstract in English or German is available. The review will include articles reporting on strategies for identification and prevention related to dental neglect in children and adolescents as conducted in health service and community settings. Data from included articles will be extracted to describe and categorise the available evidence. The review will follow recommendations of the Joanna Briggs Institute Reviewer’s Manual on scoping reviews and the Critical Appraisal Tool for Health Promotion and Prevention Reviews (CAT HPPR).

Ethics and dissemination
Ethical approval is not required, as no personal data will be collected in this literature-based study. The study’s findings will be disseminated through conference presentations, scientific publications and stakeholder meetings.

Introduction
Objective and accurate dietary monitoring is critical for comprehensive dietary assessment and improving nutritional health outcomes. The rapid advancement of wearable sensing technology presents a promising solution for effective dietary monitoring by reducing recall bias and enhancing user convenience, with potential benefits for both clinical chronic disease management and nutritional research. This systematic review aims to evaluate the effectiveness and feasibility of wearable sensors in monitoring dietary behaviours, while also examining the latest advancements in the field since 2020.

Methods and analysis
This protocol follows the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocols guidelines for systematic review reporting. We will conduct a comprehensive search across MEDLINE, EMBASE, PubMed, IEEE Xplore and Web of Science to identify studies published between January 2020 and March 2025 involving human participants using wearable sensors for dietary intake monitoring. Studies that focus solely on the development of algorithms or applications for these sensors will be excluded. The outcomes of this review will include evaluations of sensor design, performance metrics and user experience.

Ethics and dissemination
Findings of this systematic review will be disseminated through peer-reviewed journals, conferences and seminar presentations. The data used do not include individual patient data, so no ethical approval is required.
