Effectiveness of education and training programmes to help clinicians assess and classify perineal tears: a systematic review

Objective
For every 100 women having a vaginal birth, approximately four will experience a severe (third-degree or fourth-degree) perineal tear. Severe perineal tears are associated with significant short-term and long-term consequences if not recognised and repaired. There are global efforts to reduce incidence of severe perineal tears including initiatives to strengthen education and training of clinicians in perineal anatomy and perineal tear assessment and classification. This systematic review aimed to describe and evaluate the effectiveness of these initiatives.

Design
Systematic review, reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines.

Data sources
Medline (Ovid), CINAHL Complete (EBSCO), MIDIRS and EMBASE (Ovid) were searched through 15 February 2024.

Eligibility criteria
Studies reporting simple or complex interventions aimed at improving the skills and knowledge of clinicians in perineal anatomy and/or the clinical assessment and classification of perineal tears were eligible.

Data extraction and synthesis
Two reviewers independently screened studies for eligibility and appraised the quality of individual studies using the Cochrane Risk of Bias (RoB) 2.0 tool or Risk of Bias in Non-Randomised Studies of Interventions (ROBINS-I) tool.

Results
In total, 7645 citations were screened and 39 studies included. We identified nine unique interventions including training programmes, short workshops and senior obstetrician supervision. Many studies were from high-income countries, in primary care settings and at high risk of bias.

Conclusions
Effective education included practical components, such as hands-on skills and training in perineal anatomy, assessment and classification, rather than senior supervision alone. Ongoing review of practice appears to be crucial for maintaining knowledge and skills. Future research should focus on interventions tailored to limited-resource settings, and the optimal length and intensity of training programmes to assess and classify perineal tears.

Brain-Body Interactions in Ischemic Stroke: VNS Reprograms Microglia and FNS Enhances Cerebellar Neuroprotection

Stroke, Ahead of Print. Stroke significantly impacts mortality and long-term disability, necessitating effective rehabilitation strategies to enhance recovery. This review examines the roles of vagus nerve stimulation (VNS) and fastigial nucleus stimulation (FNS) in facilitating ischemic stroke recovery through brain-body interactions. VNS enhances ischemic stroke recovery by reprogramming microglia from proinflammatory (M1) to neuroprotective (M2) phenotypes, reducing neuroinflammation and promoting tissue repair via neurotrophic factors. It has shown promise in clinically improving chronic upper limb deficits when combined with rehabilitation therapies. Conversely, FNS provides cerebellar-mediated neuroprotection by mainly mitigating excitotoxic damage and inflammatory responses independent of cerebral blood flow alterations, as evidenced by preclinical models of middle cerebral artery occlusion. By integrating VNS-driven immunomodulation with FNS-mediated excitotoxicity suppression, this review highlights their synergistic potential to improve rehabilitation outcomes for ischemic stroke survivors. Biomarker-guided protocols: VNS for cortical/subcortical ischemic deficits and FNS for cerebellar network recovery are advocated to address postischemic disability via anti-inflammatory rewiring, neuroplasticity enhancement, and cerebellar-thalamocortical circuit stabilization. Critical gaps remain in hemorrhagic stroke, where FNS’s excitotoxicity suppression may destabilize clots, necessitating subtype-specific safety validations.

Burden of disease using disability adjusted life years in the Middle East and North Africa (MENA) region: protocol of a systematic review

Introduction
In the Middle East and North Africa (MENA) region, changing demographic and epidemiological profiles have resulted in a diverse and shifting burden of disease (BoD). Disability-adjusted life years (DALYs), which combine years of life lost (YLL) due to premature mortality and years lived with disability (YLD), offer a valuable metric for assessing disease burden at the national level. While global burden of disease (GBD) estimates provide broad insights, national burden of disease (NBD) estimates offer country-specific data that can better inform tailored health policies and resource allocation. This systematic review protocol outlines our methodology for collating and analysing the NBD estimates in the MENA region using DALYs as the primary outcome measure.

Methods and analysis
This review will adhere to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. We will systematically search PubMed, Scopus, Web of Science and EMBASE for studies published from 1993 to 2024 that report national-level DALY estimates for diseases, injuries or risk factors in MENA countries. Eligible studies must report DALY estimates using national methodologies, while studies using exclusively GBD estimates will be excluded. Two independent reviewers will conduct title/abstract and full-text screening, data extraction and quality assessment using Standardised Reporting of Burden of Disease Studies (STROBOD), with disagreements resolved by a third reviewer when necessary.

Ethics and dissemination
Ethical approval is not required for this review as it involves analysis of previously published data. The findings will be disseminated through publication in a peer-reviewed journal and presented at relevant academic and policy forums.

Evaluation of the outpatient parenteral antimicrobial therapy (OPAT) service in Malaysian public hospitals: a mixed-methods study protocol

Introduction
Outpatient parenteral antimicrobial therapy (OPAT) is an innovative approach to manage infections that require extended courses of intravenous antibiotics by enabling patients to receive treatment in an outpatient setting. In Malaysia, there has yet to be a systematic evaluation of the OPAT service. This study aims to describe the safety, clinical indications and treatment outcomes of the OPAT service in Malaysia, assess patients’ satisfaction and experiences and determine the facilitators and barriers associated with the provision of the OPAT service in Malaysia.

Methods and analysis
A mixed-methods approach combining qualitative and quantitative methods will be employed for a comprehensive understanding of the provision of the OPAT service in Malaysian public hospitals. The study consists of four distinct parts: systematic review, retrospective cohort analysis of clinical outcomes, patients’ satisfaction survey and focus group discussions on providers’ experiences. A longitudinal analysis of the clinical outcomes (treatment success/failure, infection cure, adverse events, readmission and mortality) of the OPAT patients’ cohort will be conducted using descriptive and conclusive statistics, in addition to rates of patients’ satisfaction and evaluation of providers’ experiences.

Ethics and dissemination
This study is registered in the National Medical Research Register (NMRR ID-24-00941-2C8) and approved by the Medical Research and Ethics Committee, Ministry of Health Malaysia (Ref: 24-00941-2C8). Written informed consent will be obtained from all participants. The results will be submitted for publication in a peer-reviewed journal and presented at one or more scientific conferences.

The emerging economic evidence and methods used to evaluate clinical registries: a systematic scoping review protocol

Introduction
A clinical registry is a systematically collected database of health-specific information about a patient population. Clinical registries can be used for a variety of purposes including surveillance, monitoring of outcomes and patient care. The establishment and maintenance of clinical registries come with a significant cost. This scoping review aims to identify the methods used to economically evaluate clinical registries including their costs and benefits.

Methods
This systematic scoping review protocol has been developed in accordance with the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P) guidelines. The final review will be reported following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) checklist. The electronic databases Medline, Embase, Cochrane Library and The Cumulative Index to Allied Health Literature(CINAHL) database will be searched. Relevant national organisation websites will be searched to identify empirical studies within grey literature. The inclusion criteria include studies that economically evaluate clinical registries and are published in the English language from inception to February 2025. Two reviewers will independently screen 100% of titles and abstracts and full texts of studies for inclusion. Data will be extracted from eligible studies prior to being assessed for quality using a multi-tool approach.

Ethics and dissemination
The findings of this review will be published in an international peer-reviewed journal. They are likely to be of interest to custodians of existing clinical registries and to those wishing to establish or evaluate clinical registries.

Randomised trial of home sleep apnoea testing compared to in-lab polysomnography for the evaluation of obstructive sleep apnoea in children: rationale and study protocol

Introduction
Obstructive sleep apnoea (OSA) affects 1–5% of the paediatric population, including 55–90% of children with Down syndrome (DS), and has been associated with negative effects on neurocognitive development, cardiovascular health, immune development and quality of life. In-lab attended polysomnography (PSG) is currently the gold standard for the diagnosis of OSA in children, but it poses challenges due to the burden on families and limited testing facilities. Home sleep apnoea testing (HSAT), an unattended sleep test done at home, is an accepted alternative for adults but lacks sufficient evidence to be used clinically for the evaluation of OSA in children. HSAT may be especially beneficial for children with DS or others with sensory issues or those who struggle with sleeping in a laboratory setting overnight.

Methods and analysis
This single-centre trial compares HSAT to PSG for the diagnosis of OSA in children, including those with DS. The trial will enrol 317 children 5–12 years old, including approximately 100 with DS. The primary outcome is the diagnostic accuracy of HSAT compared with PSG for OSA evaluated through ROC. Secondary outcomes include the agreement between HSAT and PSG for therapeutic decision-making and comparison of preference and acceptability of HSAT versus PSG. This trial seeks to evaluate HSAT as an alternative diagnostic tool for paediatric OSA, potentially expanding testing options for clinicians and families.

Ethics and dissemination
This study has been approved by the Institutional Review Board at Children’s Hospital of Philadelphia (#21–0 19 533). Informed consent will be obtained from all participants, and no identifiable data will be reported.

Effect of transcranial magnetic stimulation on perioperative neurocognitive dysfunction: study protocol for a systematic review and meta-analysis of randomised controlled trials

Introduction
Perioperative neurocognitive disorders (PNDs), a common postoperative complication associated with anaesthesia and surgical procedures, are characterised by impairments in memory, attention, language comprehension and social functioning. Accumulating evidence from clinical studies indicates that transcranial magnetic stimulation (TMS)—a non-invasive neuromodulatory modality capable of targeted cortical stimulation—may offer therapeutic promise for PND management. To comprehensively assess the intervention efficacy and safety parameters of TMS in mitigating postoperative cognitive decline, we propose conducting a systematic review and meta-analysis of randomised controlled trials adhering to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Our findings aim to provide evidence-based insights into the neuroprotective potential of TMS for mitigating cognitive decline in surgical populations.

Methods and analysis
The investigation will implement a multifaceted search protocol encompassing international and Chinese scholarly resources. The search will be conducted in major databases, including Web of Science, Embase, PubMed, Cochrane Library, China Biology Medicine, China National Knowledge Infrastructure, Wan Fang Database and Chinese Scientific Journal Database from inception to 31 March 2025. To capture the latest research trends, ongoing trials will be simultaneously searched in the WHO International Clinical Trial Registry Platform, ClinicalTrials.gov and the China Clinical Trial Registry. Grey literature will be supplemented through resources such as GreyNet International, OpenGrey and Google Scholar. The inclusion criteria for this review are restricted to randomised controlled trials investigating the application of TMS as an intervention for PND. Primary endpoints comprise clinically confirmed incidence rates of postoperative delirium and delayed neurocognitive recovery. Two researchers will independently perform literature screening, data extraction and risk of bias assessment. The risk of bias in included studies will be evaluated using the Cochrane Risk of Bias Tool 2.0. Evidence certainty will be appraised through the GRADE framework with explicit justification for downgrading decisions. Meta-analysis will be conducted using STATA V.15.1 statistical software. The data synthesis process will incorporate standardised methodologies, including heterogeneity testing, sensitivity analysis and assessment of publication bias.

Ethics and dissemination
This study will not involve the collection of biometric information or medical privacy data throughout the research process, thus complying with the exemption criteria outlined in the ‘Measures for Ethical Review of Biomedical Research Involving Human Subjects.’ The findings will adhere to academic standards and be submitted for publication in reputable international medical journals following a rigorous double-blind peer-review process.

Systematic review registration
The research protocol has been prospectively registered on the PROSPERO international prospective systematic review registration platform (registration number: CRD42025636978).

Self-administered dual-task training reduces balance deficits and falls among community-dwelling older adults: a multicentre parallel-group randomised controlled trial with economic evaluation protocol

Background
Falls are common causes of disability, reduced disability-adjusted life years and death in older adults. Balance deficits and cognitive impairment are common causes of falls. Dual-task training is a new strategy that can potentially improve balance and cognitive function, leading to decreased falls. The effectiveness and cost-effectiveness of self-administered dual-task (sDT) training to improve balance and prevent falls is not known. We developed sDT training combining physical and cognitive tasks to improve balance and reduce falls. The proposed randomised controlled trial (RCT) with economic evaluation is to test the effectiveness and cost-effectiveness of the sDT compared with self-administered single-task training (sST) in this population.

Methods and analysis
In this RCT, we will recruit 190 community-dwelling older adults with a history of at least one fall over the last 6 months from 11 elderly centres. The older adults will be randomly assigned to the sDT (n=95) and sST groups (n=95). Each group will be offered in six training workshops to teach the participants either sDT or sST depending on the group allocation. Each workshop will last an hour and will be held once every 2 weeks for 3 months. Besides, the participants will be instructed to repeat the exercises at home two times weekly for 3 months. Following the intervention phase, the participants will continue unsupervised home-based exercises for 6 months. Assessments will be performed before, after and 6 months after completing the intervention. A fall calendar and cost diary will be provided to each older adult to record the number of falls and fall-related costs during and after the intervention to assess fall incidence and cost-effectiveness. Effectiveness will be assessed using a negative binomial regression model following the intention-to-treat principle for falls and a linear mixed model for the additional measure and cost-effectiveness using a Markov model.

Ethics and dissemination
This study has ethical approval from the PolyU Institutional Review Board for conducting research on human subjects (Ref: HSEARS20210322005). The results will be disseminated through seminars for individuals and health practitioners, international conferences and published in peer-reviewed journals.

Trial registration number

Length of hospital stay and associated treatment costs for patients with susceptible and antibiotic-resistant Salmonella infections: a systematic review and meta-analysis

Objectives
The global disease burden of Salmonella infections in 2017 included 135 900 deaths caused by Salmonella Typhi and Paratyphi and 77 500 deaths caused by invasive non-typhoidal Salmonella, with increasing antimicrobial resistance (AMR) exacerbating morbidity, mortality and costs. The aim of our systematic review and meta-analysis is to estimate the length of hospital stay and associated treatment costs for patients with susceptible and antibiotic-resistant Salmonella Typhi, Paratyphi and non-typhoidal Salmonella infections.

Design
Systematic review and meta-analysis.

Data sources
We searched EMBASE, Medline/PubMed, Scopus, Hinari and LILACS databases for studies published between 1 January 2005 and 15 May 2024, with no language restrictions.

Eligibility criteria
We included 30 studies that reported the length of hospital stay or treatment costs for patients with susceptible or antibiotic-resistant Salmonella Typhi, Paratyphi and non-typhoidal Salmonella infections. We excluded studies with sample sizes of less than 30 patients, those focused on non-human subjects and those not reporting our outcomes of interest.

Data extraction and synthesis
Two reviewers independently screened studies and extracted data on the length of hospital stay and associated costs, with monetary values converted to 2019 USD. We aggregated data according to GDP per capita quantiles using a random-effects meta-analysis. We conducted a quality assessment using an adapted Joanna Briggs Institute tool.

Results
Patients with drug-resistant Salmonella infections had longer hospital stays, with an additional 0.5–2.2 days compared with drug-susceptible Salmonella infections. Based on our meta-analysis, the mean hospital stay for typhoidal Salmonella infections was 6.4 days (95% CI 4.9 to 7.8) for drug-susceptible cases and 8.4 days (95% CI 5.1 to 11.7) for resistant cases in the lowest income quartiles. While there were insufficient data to perform a pooled analysis, individual studies inferred that treatment costs for resistant typhoidal Salmonella infections were higher than for susceptible infections, and resistant non-typhoidal Salmonella infections had longer hospital stays and higher costs compared with susceptible infections. Data were scarce from high-Salmonella-burden countries, particularly in sub-Saharan Africa and parts of Asia.

Conclusions
Patients with antibiotic-resistant Salmonella infections experience a greater healthcare burden in terms of hospitalisation length and direct costs compared with those with susceptible infections. We highlight the economic burden of AMR in Salmonella infections and emphasise the need for preventive measures.

Patient-Reported Incident Measure (PRIM) tools for reporting patient safety incidents: protocol for a scoping review

Introduction
Patient safety incidents during healthcare cause a high burden and mortality, but many go unreported. Involving patients and caregivers in the identification and reporting of safety incidents would add value to the current incident reporting systems used by health professionals. Identifying and analysing patient safety incidents is essential to prevent future events, allowing organisations to apply a learning-from-error approach and to implement improvement plans. Patient-Reported Incident Measures are tools for patients and caregivers to report safety issues related to their healthcare. In accordance with WHO’s patient safety taxonomy, the term patient safety incidents is used throughout this protocol to encompass events that do and do not reach the patient, including what are commonly referred to as near misses and adverse events. We aim to identify and describe the published literature about tools for patients or caregivers to report patient safety incidents in healthcare.

Methods and analysis
We will conduct a scoping review. We have developed inclusion criteria using the PCC (population, concept and context) format, where population includes adult patients or caregivers; concept refers to documents describing formal tools used to report patient safety incidents; and context includes any healthcare setting, such as hospitals or mental health centres, during or immediately after care. The scoping review will be reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews guidelines. Evidence sources include primary research, systematic reviews, meta-analyses, conference abstracts, letters, guidelines, as well as policy documents, reports, blogs and websites, without language restriction. An initial database search in Medline, Embase, CINAHL, and Cochrane Library from database inception up to June 2023 identified 4500 initial citations, of which 4103 were selected for evaluation after duplicates were removed. We will supplement the search by checking the reference lists of included studies for additional sources of evidence and an additional search in Google to identify non-peer-reviewed documents. This initial search will be updated before completing the review. We will use a self-created data collection form for data extraction and perform a narrative synthesis to integrate and summarise the review findings. We will describe the general characteristics of the tool: setting, scope, format, content, type of patient safety incident and severity, the moment of notification, relation to patient safety incident reporting and learning systems, development process, testing, validation, or piloting, among other characteristics. As a result of this scoping review, we intend to provide an index of patient/caregiver-reported safety notification tools and a list of descriptive or evaluation studies.

Ethics and dissemination
We will only use published data. Approval from the human research ethics committee is not required. The results of this scoping review will be submitted for publication in an international peer-reviewed journal and scientific meetings. Findings will also be disseminated through digital science platforms and academic social media.

Hyperangulated videolaryngoscope for difficult airway management: a protocol for a systematic review with meta-analysis and trial sequential analysis

Introduction
Videolaryngoscopes are recommended as the top preference for tracheal intubation in adults, children, infants and neonates, and even in patients with anticipated difficult airways, since they are generally easier to use and quicker to master than fibreoptic bronchoscopes. Compared with standard videolaryngoscopes, hyperangulated videolaryngoscopes possess a more sharply curved blade or blade tip, resulting in a higher first-attempt success rate among patients with anticipated difficult airways. However, hyperangulated videolaryngoscopes also pose challenges in advancing the tracheal tube, which decreases the first-attempt success rate while increasing the tracheal intubation time when the tracheal tube introducer is unsuitable. Hence, controversy still remains regarding the efficiency of hyperangulated videolaryngoscopes as first-line devices in patients with anticipated difficult airways, owing to the inconsistent clinical findings. Consequently, we will conduct a protocol for a systematic review and meta-analysis to determine the usefulness of hyperangulated videolaryngoscopes in patients with anticipated difficult airways.

Methods and analysis
English-language databases (Web of Science, Cochrane Library, PubMed, Embase and Ovid Medline), Chinese electronic databases (VIP database, China National Knowledge Infrastructure, and Wanfang database) and clinical trial registry platforms will be scoured from their inception to May 2025 to locate randomised controlled trials of hyperangulated videolaryngoscopes in patients with anticipated difficult airways. For continuous data, mean differences or standardised mean differences, accompanied by their 95% CIs, and for dichotomous data, the risk ratio, accompanied by its 95% CI, will be calculated using Review Manager V.5.4. Either a fixed-effects model or a random-effects model will be used depending on the magnitude of statistical heterogeneity as evaluated via the I2 test. The risk of bias will be assessed via the Cochrane risk-of-bias tool 2. Additionally, the quality of evidence regarding each outcome will be evaluated using the Grading of Recommendations Assessment, Development and Evaluation. The reliability of all outcomes will be appraised via trial sequential analysis. Moreover, the publication bias of all outcomes will be examined using Funnel plots and Egger’s regression test.

Ethics and dissemination
Ethical approval was not required for this systematic review protocol. The results will be disseminated through peer-reviewed publications.

Community-based type 2 diabetes screening programmes designed for priority populations: a scoping review protocol

Background
Type 2 diabetes is a growing public health concern, and it continues to disproportionately impact priority populations. Although earlier and more frequent screening of diabetes promotes early detection to prevent adverse outcomes, this is a significant barrier for priority populations due to inequities that hinder access to critical preventive screening in primary care settings. The purpose of this scoping review is to better understand the design and implementation of screening and early detection of type 2 diabetes in community settings for priority populations to reduce missed or delayed diagnoses and future potential adverse outcomes.

Methods
This scoping review will adopt the methodological framework of Arksey and O’Malley and be enhanced using Levac et al recommendations. A search strategy was designed using insights from experienced librarians through the Peer Review for Electronic Search Strategies to conduct a comprehensive search using the following databases: Medline, Embase, PsycINFO, Web of Science, Scopus, CINAHL and Google. The search will capture studies focused on community-based diabetes screening using point-of-care testing and deployed in community settings serving priority populations with undiagnosed diabetes. Studies will be excluded if priority populations were not a focus, individuals living with diabetes, the intervention is not implemented in a community setting and did not use point-of-care screening. Two authors will independently review and screen the articles (title, abstract and full-text), while a team-based approach will be applied to chart the data. A thematic analysis will be used to identify emerging themes and subthemes according to barriers and enablers of implementing an equitable community-based diabetes screening intervention.

Ethics and dissemination
The findings from this review will inform future diabetes screening interventions in community settings to enable an equity-informed approach in the design, planning and implementation of such strategies. Equally important, it will inform a larger project, in which the team plans to implement a community-based diabetes screening programme in Ontario, Canada.
