Indian immigrants experience significant dietary acculturation post-migration, shifting from traditional diets to more westernised eating patterns influenced by socioeconomic and environmental factors. This transition, often marked by increased processed food consumption and reduced intake of traditional staples, contributes to elevated risks of obesity and type 2 diabetes. Despite the growing Indian diaspora in Australia, Canada, New Zealand and the UK, the evidence on their dietary acculturation remains limited.

This review will adopt the Joanna Briggs Institute (JBI) methodology for scoping reviews. A three-step search strategy will be applied across databases including MEDLINE (via PubMed), CINAHL, Scopus and Web of Science. Google Scholar will be used as a supplementary search tool to identify additional relevant studies. The search will include peer-reviewed studies and grey literature published in English between 1 January 2000 and 22 May 2025. First-generation Indian immigrants of all ages will be included, while second-generation immigrants, refugee populations and studies linked to non-communicable disease interventions will be excluded. Screening will be conducted in Covidence by two independent reviewers, with discrepancies resolved by a third reviewer. Data will be extracted using a standard JBI tool, charted in tabular form, and synthesised narratively and thematically.

As this review will use published and publicly available data, formal ethics approval is not required. Findings will be disseminated through peer-reviewed publication, conference presentations and community engagement.

Sympathetic activation is the hallmark of cardiac disease, driving disease progression and triggering ventricular arrhythmia (VA). Despite optimal medical therapy, many patients experience recurrent VAs refractory to medical therapy, leading to repetitive implantable cardioverter defibrillator (ICD) therapy, worse quality of life and adverse outcomes. Cardiac sympathetic denervation (CSD) through surgical removal of the stellate ganglia is an effective treatment for refractory VAs but carries a high complication rate. We hypothesise that high precision image guided radiotherapy can be used to target the stellate ganglia to achieve CSD non-invasively.

RADIO-STAR (hypofractionated radiotherapy to the stellate ganglia for ventricular arrhythmia) is a first-in-human, phase 1 safety and dose finding study of radiotherapy to the stellate ganglia in patients with recurrent VAs. Patients with structural heart disease requiring recurrent ICD therapy for VAs are invited to undergo radiotherapy bilaterally to their stellate ganglia with a predetermined sample size of n=13. Radiotherapy dose will be determined by a prespecified dose escalation protocol. The primary outcome is safety defined as any treatment-related grade 3–5 toxicity occurring within 6 months of radiotherapy treatment, as defined by the Common Terminology Criteria for Adverse Events or any treatment-related side effects detected on patient symptom questionnaires and clinical examination during study visits. Secondary outcome measures to evaluate feasibility and efficacy include ability to safely deliver radiotherapy and consequent changes in circulating catecholamines and neuropeptide-Y, heart rate variability, structural changes in the stellate ganglia on MRI imaging and ICD therapy burden.

This study has received ethical approval by the South Central—Oxford B Research Ethics Committee (REC/SC/0005). Study findings will be submitted for publication in peer-reviewed scientific journals and presented at national and/or international scientific conferences.

Cognitive behavioural therapy (CBT) and interpersonal psychotherapy (IPT) are both efficacious treatments for depression, but it is less clear how both compare on outcome domains other than depression and in the longer term. Moreover, it is unclear which of these two psychotherapies works better for whom. This article describes the protocol for a systematic review and individual participant data (IPD) meta-analysis that aims to compare the efficacy of CBT and IPT for adults with depression on a range of outcomes in both the short and long term, and to explore moderators of the treatment effect. This study can enhance our understanding of treatments for depression and inform treatment personalisation.

Systematic literature searches will be conducted in PubMed, PsycINFO, EMBASE and the Cochrane Library from inception to 1 January 2026, to identify randomised clinical trials (RCTs) comparing CBT and IPT for adult depression. Researchers of eligible studies will be invited to contribute their participant-level data. One-stage IPD meta-analyses will be conducted with mixed-effects models to examine (a) treatment efficacy on all outcome measures that are assessed at post-treatment or follow-up in at least two studies, and (b) various baseline participant characteristics as potential moderators of depressive symptom level at treatment completion.

Ethical approval is not required for this study since it will be based on anonymised data from RCTs that have already been completed. The findings of the present study will be disseminated through a peer-reviewed journal or conference presentation.

Gram negative bloodstream infections (GN BSI) are a leading cause of mortality worldwide, and antibiotic treatment approaches remain understudied. BALANCE+ is a perpetual Bayesian adaptive platform trial to test multiple treatment questions for hospitalised patients with GN BSI. The vanguard phase objective was to test the feasibility of the main trial.

Adaptive platform trial with five initial domains of investigation, each with open label 1:1 randomisation.

Ten hospitals across four Canadian provinces.

Individuals admitted to hospital with blood cultures yielding Gram negative bacteria.

The five initial domains of investigation included: antibiotic de-escalation versus no de-escalation; oral transition to beta-lactam versus non-beta-lactam treatment; routine versus no routine follow-up blood cultures (FUBCs); central vascular catheter replacement versus retention; and, ceftriaxone versus carbapenem treatment for low risk AmpC organisms.

Domain-specific recruitment rates and protocol adherence.

During the vanguard phase, 719 patients were screened, of whom 563 (78.3%) were eligible, with 179 (31.8%) enrolled into the platform. The platform recruitment rate was 1.37 patients/site-week. Recruitment varied by domain: routine versus no FUBC domain 1.23 patients/site-week; oral beta-lactam versus non-beta-lactam domain 0.48; de-escalation versus no de-escalation domain 0.28; low risk AmpC domain 0.02; catheter replacement versus retention domain 0.01. Domain specific protocol adherence rates were 145/158 (91.8%) for routine versus no routine FUBC, 53/60 (88.3%) for oral beta-lactam versus non-beta-lactam, 26/33 (78.8%) for de-escalation versus no de-escalation, 3/3 (100%) for low risk AmpC, and 0/1 (0%) for line replacement versus retention. There was complete ascertainment of all study outcomes in hospital 170/170 (100%) and near complete ascertainment at 90 days 162/170 (95.3%).

The vanguard phase demonstrated overall trial feasibility by recruitment rate and protocol adherence, with differences across interventions, leading to a transition to the main BALANCE+ platform trial with minimal protocol modifications.

To assess maternal medical conditions, physical and surgical ailments, contraceptive use and barriers to its use, maternal mental health, neonatal health, breastfeeding practices and available social support in the postpartum period.

A prospective cohort study.

A large tertiary care centre.

12 245 women who delivered after 22 weeks gestation in the year 2022.

Three pre-specified exposures, namely mode of delivery, presence of significant risk factors and preterm delivery within the cohort, were used to identify potential groups of women who would need additional support.

The primary outcome was the number of unscheduled visits by the mother or child and the indications for these visits.

The secondary outcomes in mothers included unhealed wound sites, anaemia, increase in body mass index (BMI) by >3, persistent high blood pressure, pain in the abdomen or pelvis, urinary or bowel problems, musculoskeletal pain, abnormal maternal mental health, breast-related issues and barriers to breastfeeding, contraceptive use and sexual activity.

Only 2% of women and children were lost to follow-up. Nine women and 75 babies died. The majority of infant deaths were related to serious congenital diseases. Unscheduled visits to the health facility were seen in 44% of the cohort, most commonly for upper respiratory infections and fever in the mother and baby. 41 mothers and 741 infants needed admission to hospital. Hospitalisation was more common in those with risk factors or preterm delivery. High blood pressure was seen in 3 to 4% and anaemia in 4% of the cohort. Wound infection was seen in 3 to 4% and urinary incontinence in 2% of women. Wound infection was more common with instrumental delivery. Bowel incontinence was rare. A fourth of the cohort had musculoskeletal pain, especially back pain, which was more common after caesarean delivery. Only 5.5% of the cohort had unsatisfactory mental health, and these women were more likely to have abnormal mental health scores with the NICE Questionnaire at screening. The family APGAR of the cohort was 9/10, and 95% belonged to the middle-income group. 2.6% of neonates had delayed milestones, and this was more common in the group with risk factors and preterm delivery.

Healthcare utilisation was mainly for minor complaints. Re-admissions were rare, as intrapartum and immediate postpartum care were optimal. Women who delivered by caesarean section or delivered a preterm child needed additional support in the postpartum phase. NICE Questionnaire is a quick and easy screening tool to identify unsatisfactory mental health and should be used before discharge, postnatally, even in busy settings. The implementation of formal telephonic support 24 hours a day in birthing facilities should be explored in the future. Holistic postnatal care of mother and child during the immunisation of the baby would be the best opportunity to improve the quality and coverage of care in the postnatal phase.

Alcohol is consumed by an estimated 137.4 million people in the USA 12 years of age and older and, as a result, is estimated to have caused about 140 thousand deaths among people 20 to 64 years of age each year from 2015 up to and including 2019.

The proposed review of the evidence on alcohol’s impact on health aims to produce conclusions to inform the Dietary Guidelines for Americans, 2026–2030. A multi-method approach will be utilised to formulate conclusions on (i) weekly (ie, average) thresholds to minimise long-term and short-term risks of morbidity and mortality, (ii) daily thresholds to minimise the short-term risk of injury or acute illness due to per occasion drinking, (iii) alcohol use among vulnerable populations (eg, pregnant women) and (iv) situations and circumstances that are hazardous for alcohol use. To inform expert decisions, this project will also include a systematic review of existing low-risk drinking guidelines, a systematic review of meta-analyses which examine alcohol’s impact on key attributable disease and mortality outcomes, and of estimates of the lifetime absolute risk of alcohol-attributable mortality and morbidity based on a person’s sex and average level of alcohol use. The systematic reviews were designed in accordance with the preferred reporting items for systematic review and meta-analysis protocols (PRISMA-P). The preliminary conclusions produced as a result of this project will undergo public consultation, and data from these consultations will be qualitatively analysed. The results of the public consultations will be used to further revise and refine the project’s conclusions.

The study was granted an ethics exemption as only secondary data sources and unidentifiable public consultation will be utilised. Systematic reviews are pre-registered with PROSPERO (registration numbers CRD42024584924 and CRD42024584948).

This project will establish a scientific consensus concerning alcohol’s impact on health. This consensus is imperative for informing the upcoming Dietary Guidelines for Americans, 2026–2030, and for better informing individuals about the health risks associated with alcohol use.

Worldwide, there are 15 established trauma databases collecting data to better understand the patterns of injury and effectiveness of interventions, but interpreting the information is hampered by the varied approaches. The aim of this study was to determine the impact, practices, evolution in design and methods of analysis that are standardised and comparable within registries.

A thematic analysis using a narrative synthesis was used to develop threads for future study and identify the limitations in current practice.

PubMed, Ovid, Scopus and EMBASE were searched on the 2 October 2025. At the same time, ChatGPT (Open artificial intelligence) identified the most cited articles in orthopaedic trauma registries, cross-referencing lists as a form of triangulation to aid in snowballing references.

The review included 174 papers from trials and observational studies that analyse data from established trauma orthopaedic registries published in English.

Two independent reviewers used standardised methods to search, screen and code included studies assessing the papers using the Strengthening the Reporting of Observational Studies in Epidemiology checklist to assess the observational and cohort studies and the Downs and Black Quality Criteria for the remaining papers.

Outcome measures other than mortality are poorly collected, undermining the value of registries. Trauma patients reported considerable impairment 6 and 12 months after injury. Association between level of trauma care and mortality is evident for major trauma populations, but does not hold for general trauma populations. Level I trauma centres produce improved survival in severely injured, but this association could not be proven for non-fatal outcomes in general populations. There is a disparity between resources allocated to save and salvage cases within major trauma units, and hence, routine cases often have lower priority and delayed care.

There is a need to develop a standardised and reproducible method to evaluate data quality in trauma registries. National performance guidelines and trauma centre audits are integral steps towards optimum results. Routine collection of postinjury outcome measures beyond mortality will enable the development of quality improvement metrics that better reflect patient outcomes.

Metacognitive strategy training is a crucial approach for addressing metacognitive deficits and enhancing metacognitive abilities, which can help mitigate age-related cognitive decline and optimise cognitive functioning. The present scoping review aims to systematically examine and synthesise the existing evidence on metacognitive strategy training programmes designed for both neurotypical adults and individuals with cognitive-communication disorders (CCDs).

A scoping review following the JBI methodology.

A literature search was conducted systematically across PubMed, Embase and Web of Science between June and August 2024.

Studies involving metacognitive strategy training for neurotypical adults or individuals with CCDs, measuring cognition, communication or metacognitive skills.

Two reviewers independently screened studies in a two-step process, that is, title and abstract screening followed by full-text screening. Data extraction included study characteristics, participant demographics, intervention details and outcome measures.

A total of 32 studies met the selection criteria, revealing diverse metacognitive training approaches that varied in component and dosage. The most frequently used approaches are the Cognitive Orientation to Occupational Performance approach and the Multicontext approach. The reported outcome measures included cognitive outcomes, metacognitive outcomes, well-being measures and feasibility measures. The majority of interventions targeted occupational goals, followed by cognitive skills, with fewer studies addressing cognitive-communicative skills. Studies have focused primarily on individuals with CCDs, with only a few targeting neurotypical adults.

Studies examining the efficacy of metacognitive strategy training are heterogeneous in terms of population, intervention approaches, and outcome measures. There is significant potential to expand the focus of these interventions to include neurotypical adults, aiming to counteract age-related cognitive-communicative disorders. The limited research within the field of speech-language pathology presents a valuable opportunity for speech-language pathologists to broaden the application of metacognitive strategy training, particularly in enhancing cognitive-communicative abilities.

The rapidly growing population of older adults (individuals aged 65 years and older) presents a new set of challenges for healthcare providers in the emergency department (ED), given the prevalence of severe and life-threatening conditions among this group, such as chronic cancer, Alzheimer’s disease/dementia and congestive heart failure. ED encounters often represent a critical point in an older patient’s trajectory of care and can thus be an important opportunity for various interventions such as palliative care consultation. Therefore, identifying those who will benefit most from palliative care is of high importance, especially in determining the course of future treatment. Thus, we aim to conduct a systematic review assessing the efficacy of palliative care screening in the ED by assessing inpatient length of stay as the primary outcome and quality of life, percentage of hospitalisation and cost of care as secondary outcomes.

This study will use Ovid MEDLINE, Embase, EBSCO CINAHL, Web of Science and Cochrane as databases. The study population comprises adults aged 60 years and older, with no focus on any specific clinical specialty or disease. Patients who have not received palliative care screening will serve as the comparator. Only studies with an applicable comparator will be considered. Studies published from 1 January 2000 to 1 July 2025 will be included.

All articles will be reviewed independently and in duplicate, and every author will participate in the review, data abstraction and conflict resolution process.

Ethical approval is not required as it is a protocol for a systematic review. Findings will be disseminated through peer-reviewed publications and conference presentations.

Improving outcomes from sepsis in children is a WHO Global Health Priority, yet mortality from sepsis remains high, particularly in low- and middle-income countries (LMICs). This database from children with community-acquired childhood sepsis in LMICs and some high-income countries will allow analysis of the burden of disease, including incidence, severity and outcomes. Understanding these aspects of sepsis care is fundamental for the design and conduct of future international interventional trials to improve childhood sepsis outcomes.

This multicountry retrospective observational study will include children up to 18 years of age presenting to emergency departments with suspected sepsis, defined as admission to hospital for treatment with intravenous antibiotics plus (1) a provisional diagnosis of sepsis and/or (2) treatment for suspected sepsis (operationalised as the administration of one or more fluid bolus to treat impaired perfusion or vasoactive infusion). Presenting characteristics, management and outcomes will be collected. These will include vital signs, serum biomarkers, intravenous fluid administration for the first 24 hours of hospitalisation, organ support therapies delivered, antimicrobial use, microbiological diagnoses, hospital and intensive care unit length of stay, and mortality censored at hospital discharge or 30 days from enrolment (whichever occurs first).

Central ethics approval was received from the Royal Children’s Hospital of Melbourne, Australia Human Research Ethics Committee (HREC/100648/RCHM-2023). Each international site will be required to obtain local Institutional Research Ethics Board approval. The findings will be disseminated in peer-reviewed journals, at academic conferences and through lay media. A cleaned study database and individual site-level data will be made available to site investigators upon completion of the study.

This study was registered with the Australian and New Zealand Clinical Trials Registry on 23 January 2024 prior to commencement of recruitment (ACTRN12624000052538).

Leishmaniasis poses a significant public health problem in Kenya, where effective case management and treatment rely on accurate diagnosis. This review aims to summarise the research landscape on leishmaniasis diagnostics in Kenya and identify gaps.

This scoping review expands a previously published scoping review on leishmaniasis in Kenya to further analyse studies focusing on diagnostics. The field of diagnostics was chosen because of recent pushes for novel tools and because of the role timely diagnosis plays in disease elimination. A comprehensive search of PubMed, Embase via Embase.com, Web of Science Core Collection, the Cochrane Library, ClinicalTrials.gov, WHO ICTRP and the Pan African Clinical Trials Registry was conducted, covering studies up to 5 January 2024.

After dual, blind screening with conflict resolution by a third reviewer, 41 studies were included in the review. These studies examined a range of diagnostic tools; however most were assessed in one or few studies, and none evaluated real-time PCR. Additional gaps in the research landscape include a lack of diagnostics for cutaneous leishmaniasis and post-kala-azar dermal leishmaniasis in Kenya, outdated literature surrounding the Direct Agglutination Test and randomised trials for any diagnostic tool.

Future research should focus on solidifying the validity and reliability of diagnostic tools in the Kenyan context and updating previous work.
