Por: Taveira · R. S. · Vasconcellos · L. S. d. · Bezerra · C. F. · Aires · D. N. · Dias de Oliveira · A. K. · da Silva · K. d. O. C. · Melo · L. P. d. · Ribeiro · T. S.
Introduction

Telerehabilitation (TR) programmes are increasingly recognised for their feasibility and potential benefits, such as eliminating travel time, reducing costs and providing a more comfortable rehabilitation experience at home. However, the comparative efficacy of remote physiotherapy compared with traditional in-person sessions for individuals with Parkinson’s disease (PD) remains uncertain. This study aims to evaluate the effects of TR compared with in-person physiotherapy in individuals with PD, focusing on both motor and non-motor outcomes.

Methods and analysis

This is a randomised, single-blind clinical trial with a mixed-methods approach. A total of 22 individuals diagnosed with PD will be randomly assigned to one of two groups. The experimental group will receive TR, consisting of remote physiotherapy sessions conducted once a week for 1 hour over a 4-month period. The control group will receive the same interventions in person. Interventions will include global muscle strengthening exercises, balance training, gait and motor coordination exercises, and cognitive training. The primary outcome will be motor function, measured using part III of the Movement Disorder Society–Unified Parkinson’s Disease Rating Scale. Secondary outcomes will include cognition (Montreal Cognitive Assessment), gait (Functional Gait Assessment), mobility (Timed Up and Go Test) and quality of life (Parkinson’s Disease Questionnaire). Data will be analysed using repeated measures analysis of variance to compare outcomes between groups across four assessment points (baseline, midpoint, postintervention and 2 months follow-up). Additionally, a qualitative phase will explore participants’ perceptions and experiences regarding TR and in-person interventions, with assessments carried out 2 months after the completion of the 24-week interventions, through semistructured interviews that will be analysed using Bardin’s Content Analysis technique.

Ethics and dissemination

This protocol was approved by the Research Ethics Committee of the Federal University of Rio Grande do Norte (approval number: 5.553.701). All participants will provide written informed consent before inclusion. Results will be disseminated through peer-reviewed publications, scientific conferences and communication with participants and healthcare professionals.

Study protocol for a randomised controlled trial to determine the efficacy of lisdexamfetamine for the treatment of acute methamphetamine withdrawal in inpatient settings

Por: Acheson · L. S. · Siefried · K. J. · Lintzeris · N. · Dunlop · A. J. · Haber · P. S. · Arunogiri · S. · Christmass · M. · Doyle · M. · Donoghoe · M. · Nagle · J. · Clifford · B. · McKetin · R. · Lubman · D. I. · Brett · J. · Taylor · N. · Carr · A. · Levin · F. R. · Shoptaw · S. · Ezard · N
Introduction

Harms due to methamphetamine use disorder (MAUD) are rising globally. Untreated withdrawal symptoms perpetuate the cycle of dependence and are a barrier to treatment. There is no pharmacotherapy approved for methamphetamine withdrawal. Lisdexamfetamine (LDX) dimesylate has potential as an agonist therapy to ameliorate symptom severity during acute methamphetamine withdrawal and increase duration of initial abstinence and retention in treatment.

Methods and analysis

We will conduct a double-blind, randomised, controlled trial to evaluate the efficacy of LDX in reducing symptom severity during acute methamphetamine (MA) withdrawal. One hundred eighty-four adults with moderate to severe MAUD presenting to a health service requesting MA withdrawal treatment who report use of MA within the last 72 hours will be recruited. Participants will be randomised 1:1 to receive a tapering dose of lisdexamfetamine (250 mg on day 1, reducing by 50 mg per day to 50 mg on day 5, followed by 2 days of placebo washout on days 6 and 7), or placebo for 7 days. The study will be conducted over 7 days in an inpatient unit, and all participants will also receive standard inpatient withdrawal care. Participants will be followed up in the community to day 84. The primary outcome is efficacy, defined as the between-group difference in average withdrawal severity measured over the 7-day admission by the Amphetamine Withdrawal Questionnaire. Secondary outcomes are retention in treatment, treatment satisfaction, sleep and concomitant medication use (symptomatic medications and medications for other indications to day 7); safety, craving for MA, post-treatment withdrawal symptoms, depression, anxiety and stress, insomnia and cost effectiveness (to day 28) and MA use, mental, physical and social health and post-withdrawal treatment utilisation (to day 84). A First Nations qualitative substudy will assess the experiences of Aboriginal and Torres Strait Islander participants, ensuring the treatment meets the needs of First Nations people.

Ethics and dissemination

This protocol was first approved by the St Vincent’s Hospital Human Research Ethics Committee on 15/05/2024 (2024/ETH00788). All participants will be provided with a participant information sheet and consent form, be fully informed about the study and given ample time to consider participation. Results will be published in peer-reviewed journals and presented at national and international conferences. Findings will be presented such that individual participants will not be identifiable.

Prevention of postamputation pain with targeted muscle reinnervation (PreventPAP trial): protocol for a national, multicentre, randomised, sham-controlled trial

Por: Tendijck · G. A. H. · van Schaik · J. · Dijkman · R. R. · Niesters · M. · van Zwet · E. W. · van den Hout · W. B. · Ploeg · A. J. · van Rijt · W. G. · de Ruiter · G. C. W. · Coert · J. H. · Duraku · L. S. · Zuidam · J. M. · van de Water · W. · Pondaag · W. · van der Krogt · H. · Groe
Introduction

In the Netherlands, approximately 2200 major amputations of the lower extremities are performed each year, the majority in vascular patients. Around 61% of these patients will develop postamputation pain (PAP). PAP is a severe, lifelong, disabling condition profoundly affecting quality of life. During amputations, the common practice is to cut the nerves without employing nerve-surgical techniques to prevent chronic pain due to neuroma formation. In recent years, targeted muscle reinnervation (TMR) has been the most frequently studied technique for treating PAP, inhibiting neuroma formation by rerouting the cut mixed nerve to a functional motor nerve. We hypothesise that a primary TMR procedure during major lower limb amputations will result in a lower prevalence of PAP.

Methods and analysis

We propose a national, multicentre, randomised, sham-controlled trial comparing TMR with traction neurectomy in major amputations of the lower extremities in patients with vascular disease. 203 patients will be recruited with an indication for a transfemoral to transtibial amputation as a primary or secondary sequela of vascular disease. The subjects are randomly assigned to the TMR group or the traction neurectomy group. PAP will be evaluated 1 year postoperatively as the primary endpoint. Secondary outcomes include quality of life, mobility, neuropathic pain, hospital anxiety and depression, cost-effectiveness and complications.

Ethics and dissemination

This study has been reviewed and approved by the local ethical review body, ‘The Medical Ethics Committee Leiden The Hague Delft’, under the reference: P24.073 on 28 November 2024. Results will be published in peer-reviewed journals.

Developing consolidated guidelines for reporting and evaluation of studies using transcranial electrical stimulation (CoRE-tES): protocol for an international Delphi study and expert consensus process

Por: Suhood · A. Y. · Summers · S. · Pascual-Leone · A. · Nitsche · M. A. · Ziemann · U. · Bikson · M. · Lefaucheur · J.-P. · Brunoni · A. R. · Bestmann · S. · Chipchase · L. S. · Razza · L. B. · Cavaleri · R.
Introduction

In recent decades, transcranial electrical stimulation (tES) has become a widely used non-invasive method for modulating brain function in clinical and non-clinical populations. However, existing tES trials exhibit substantial methodological heterogeneity, often limiting the reproducibility and interpretability of findings. There currently exists a paucity of consensus-driven, standardised recommendations outlining the key factors that should be reported and/or controlled in tES studies. Accordingly, this project aims to develop Consolidated Guidelines for Reporting and Evaluation of studies using tES (CoRE-tES), a tool designed to assess the methodological quality and reporting of laboratory-based and home-based tES studies. These guidelines will support improved quality, consistency, replication and transparency in research involving tES modalities, including transcranial direct current stimulation, transcranial alternating current stimulation and transcranial random noise stimulation.

Methods and analysis

CoRE-tES will be developed and disseminated over five stages. Stage 1 will comprise a review of recent tES literature to assess methodological and reporting quality. Stage 2 will employ a Delphi process to seek agreement among international tES experts on a list of items for inclusion in CoRE-tES. In stage 3, a consensus meeting will be held to synthesise and prioritise the agreed items to form CoRE-tES. Stage 4 will involve production of the final CoRE-tES checklist and an accompanying evaluation and elaboration document. In stage 5, CoRE-tES will be disseminated via journal publication, conferences, professional meetings and social media campaigns.

Ethics and dissemination

Ethics approval has been obtained from the Western Sydney University Human Research Ethics Committee (approval number H16803). Findings will be disseminated through scientific conferences and peer-reviewed journal publications, and CoRE-tES will be indexed on the Enhancing the QUAlity and Transparency Of health Research Network website.

Assessing the impact of a semi-structured intraoperative anaesthesia handoff cognitive aid on surgical patient outcomes: study protocol for a cluster randomised trial

Por: Samost-Williams · A. · Green · C. E. · Kao · L. S. · Sridhar · S. · Sessler · D. I. · Turan · A. · Thomas · E. J.
Introduction

Intraoperative anaesthesia handoffs represent a risk point in the care of surgical patients. Although often necessary to prevent fatigue, improve vigilance and optimise operational efficiency, critical information can be lost, potentially leading to postoperative complications. Structured handoffs can increase the transfer of knowledge during intraoperative anaesthesia handoffs, improving their quality. We therefore propose to test the primary hypothesis that a semi-structured intraoperative anaesthesia handoff cognitive aid reduces the number of serious 30-day complications in surgical patients.

Methods and analysis

We will enrol adults having non-cardiac surgery who are scheduled to have an intraoperative anaesthesia handoff for operational reasons. We plan a cluster randomised trial (enrolling over 18 months, anticipated sample size approximately 4500 patients) that will compare the Epic Electronic Health Record intraoperative anaesthesia handoff cognitive aid to routine handoffs. Our primary outcome will be the number of serious postoperative complications within 30 days. Our secondary outcomes will be: (1) the number of minor complications; and (2) the duration of postoperative hospitalisation. Bayesian analysis with generalised linear multilevel modelling will be used to estimate the effect of structured handoffs on the primary and secondary outcomes.

Ethics and dissemination

This study has been approved by the local institutional review board with a waiver of informed consent. Results will be disseminated in the medical literature with de-identified data available on request.

Prognostic significance of tumour-infiltrating T lymphocytes in ovarian cancer: a protocol for systematic review and meta-analysis

Introduction

Ovarian cancer remains a significant clinical challenge due to its aggressive nature and high mortality rate. Tumour-infiltrating lymphocytes (TILs) play a critical role in the tumour microenvironment, influencing treatment response and patient survival across various cancer types, including ovarian cancer. A systematic review is warranted to consolidate evidence on TILs as prognostic biomarkers in ovarian cancer, with the goals of integrating them into clinical practice to enhance patient outcomes. This study aims to assess the prognostic significance of TILs in ovarian cancer.

Methods and analysis

A comprehensive literature search will be conducted across multiple databases, including PubMed, Embase, Web of Science, Scopus, Cochrane Library, CINAHL, ScienceDirect and LILACS. No restrictions regarding publication date or language will be applied. Original studies evaluating the role of TILs in women with ovarian cancer will be considered for inclusion. Two independent authors will screen titles and abstracts, and any discrepancies will be resolved through discussion with a third author. The risk of bias in included studies will be assessed using the Quality in Prognosis Studies (QUIPS) tool. Data synthesis will be performed using R software (V.4.3.1).

Ethics and dissemination

This study reviews the published data; thus, obtaining ethical approval is unnecessary. The findings of this systematic review will be published in a peer-reviewed journal.

ColoCap: determining the diagnostic accuracy of colon capsule endoscopy compared with standard colonoscopy in patients at risk of colorectal disease - a study protocol

Por: Ibrahim · H. · Haritakis · M. · Ballantine · L. · McCormack · K. · Cotton · S. · Hudson · J. · Atkin · K. · Rogers · S. · Nixon · L. S. · Verghese · A. · Holmes · H. · Treweek · S. · MacLennan · G. · Dolwani · S. · Gardner · G. · Hurt · C. · Watson · A. · Turvill · J.
Background

Lower gastrointestinal symptoms attributed to colorectal disease are common. Early diagnosis of serious colorectal disease such as colorectal cancer (CRC), precancerous growths (polyps) and inflammation is important to ensure the best possible outcomes for a patient. The current ‘gold standard’ diagnostic test is colonoscopy. Colonoscopy is an invasive procedure. Some people struggle to cope with it and require intravenous sedation and/or analgesia. It is also resource-intensive, needing to be performed in specialist endoscopy units by a trained team. Across the UK, the demand for colonoscopy is outstripping capacity and the diagnosis of colorectal disease is being delayed. A colon capsule endoscope (CCE) is an alternative colorectal diagnostic. It is a ‘camera in a pill’ that can be swallowed and which passes through the gastrointestinal tract, obtaining visual images on the colon. There is now established experience of CCE in the UK. CCE might provide a less invasive method to diagnose colorectal disease if found to be accurate and effective and provide a means by which to increase the National Health Service (NHS) diagnostic capacity.

Aims and objectives

The aim of this study is to determine the diagnostic accuracy of CCE when compared with colonoscopy in representative and clinically meaningful cohorts of patients. An evaluation of the experiences of CCE for the patient and clinical team and an assessment of cost effectiveness will be undertaken.

Methods

We will undertake three research workstreams (WS). In WS1, we shall perform a paired (back-to-back) study. Each participant will swallow the CCE and then later on the same day they will have a colonoscopy. The study has been designed in collaboration with our Patient Advisory Group and as closely mirrors standard care as is possible. 973 participants will be recruited from three representative clinical contexts; suspected CRC, suspected inflammatory bowel disease and postpolypectomy surveillance. Up to 30 sites across the UK will be involved to maximise inclusivity. Measures of diagnostic accuracy will be reported along with CCE completion rates, number of colonoscopy procedures potentially prevented and adverse events, such as capsule retention. A nested substudy of intraobserver and interobserver agreement will be performed. WS2 will develop models of cost-effectiveness and WS3 will evaluate the patient and clinician experience, with reference to acceptability and choice.

Anticipated impact

The study findings will provide the evidence base to inform future colorectal diagnostic services.

Ethics and dissemination

The study has approval from the North East—Tyne and Wear South research ethics committee (REC reference 24/NE/0178, IRAS 331349). The findings will be disseminated to the NHS, National Institute for Health and Care Excellence, other clinical stakeholders and participants, patients and the public.

PUTRA-CV study protocol: a multicentre observational study of ethnic-specific genetic variants and dietary patterns in relation to lipoprotein(a) levels and their association with coronary artery disease severity in Malaysian adults

Por: Pannirselvam · S. · C Thambiah · S. · Appannah · G. · Ling · K. H. · Samsudin · I. N. · Hooper · A. J. · Yusoff · M. R. · Zakaria · A. F. · Razali · R. · Kiong · G. L. S. · Zahari Sham · S. Y. · Lai · Y. Y. · Abdul Rahman · T. H. · Zainal Abidin · I.
Introduction

Although low-density lipoprotein cholesterol (LDL-C) is established as the primary cardiovascular disease (CVD) risk factor, some individuals with LDL-C within desirable limits still develop coronary artery disease (CAD). Lipoprotein(a) (Lp(a)) has emerged as a genetically determined independent risk factor for CVD. This study aims to investigate Lp(a) by determining its association with coronary artery stenosis severity, identifying its ethnic-specific genetic determinants and assessing its relationship with an energy-dense dietary pattern.

Methods and analysis

The PUTRA-CV study is a 3-year, multicentre, case-control observational study involving adult patients who have undergone coronary angiography. The primary outcome is the association between Lp(a) levels and the severity of angiographic CAD (assessed by Gensini or Syntax score). Secondary outcomes include the frequencies of Lp(a)-associated single nucleotide polymorphisms (SNPs) (rs10455872 and rs3798220) and the association between dietary patterns and Lp(a) levels. Lp(a) will be measured using a particle-enhanced immunoturbidimetric method, and SNPs will be genotyped using high-resolution melting. Dietary intake will be assessed using a validated semiquantitative food frequency questionnaire. Data will be analysed using SPSS. Descriptive statistics will be used to summarise population characteristics. Bivariate analyses will use chi-square (2), independent t-tests or Mann-Whitney U tests as appropriate. The independent association between Lp(a) and coronary artery stenosis severity will be determined using multivariable logistic regression, adjusting for confounders. Empirically driven dietary patterns will be derived using reduced rank regression, and their association with Lp(a) will be assessed. For genetic analysis, allele frequencies of the LPA SNPs rs10455872 and rs3798220 will be calculated and compared between cases and controls.

Ethics and dissemination

Ethical approval has been obtained from the ethics committees of the Ministry of Health Malaysia (NMRR ID-24-00877-2ID-IIR), Universiti Putra Malaysia (JKEUPM-2024–246), Universiti Teknologi MARA (REC/07/2024-OT/FB/2) and Universiti Malaya Medical Centre (MREC ID NO: 2 02 453–13692). The findings will be disseminated via peer-reviewed journals and conferences.

Food environment of traditional peoples and communities: a scoping review protocol

Por: Barbosa · B. B. · Tavares · N. H. C. · Adriano · L. S. · Mendes · L. L. · Carioca · A. A. F.
Introduction

Traditional peoples and communities (TPCs), such as indigenous peoples and quilombolas (communities descended from escaped African slaves), face challenges related to food security and the impact of the food environment on their health. Changes in food systems, urbanisation and loss of territorial rights have contributed to less healthy eating patterns, with increased consumption of ultra-processed foods and a higher prevalence of chronic non-communicable diseases. Despite this, there are gaps in knowledge about how the food environments of these communities are investigated, especially in relation to the physical, economic, political and sociocultural dimensions.

Methods and analysis

This scoping review will be conducted following the methodological framework developed by the Joanna Briggs Institute for scoping reviews, and its reporting will adhere to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses-Extension for Scoping Reviews checklist. A systematic search will be carried out in the following databases: PubMed, SciELO, Web of Science, Embase and EBSCO, using terms related to traditional populations and food environments. The studies to be included will be selected according to the inclusion and exclusion criteria defined based on the population, concept and context technique. The study population will include TPCs, such as indigenous peoples and quilombolas; the concept will address the food environment in its physical, economic, political and sociocultural dimensions; and the context will encompass studies conducted at a global level, without any restrictions on geographic location. The study type will include original articles and grey literature. The screening of studies will involve independent reviewers and predefined inclusion and exclusion criteria. Data synthesis will be presented in tables, including information on focus, geographic scope and methodology of the selected studies. The risk of bias will be assessed using the Risk of Bias in Non-randomised Studies of Exposure tool.

Ethics and dissemination

As the study does not involve the collection of primary data or human participants, it does not require ethical approval. The results will be submitted to peer-reviewed journals and presented at public health and nutrition conferences, contributing to the advancement of knowledge on food environments of TPCs.

Development of a core outcome set for the trials of complementary therapies in people with multiple sclerosis: international survey and consensus meetings

Por: Lopez-Alcalde · J. · Tietjen · A. K. · Yan · Y. · Canella · C. · Barth · J. · Steinemann · N. · Hägele-Link · S. · Bolt · S. · Baum · C. · Rettenmund · G. · von Wyl · V. · Nonino · F. · Wieland · L. S. · Wang · X. · Schmick · A. · Pagnini · F. · Kesselring · J. · Khazaei · H. · Perez-Ner
Objectives

This study aimed to develop a core outcome set (COS) for trials evaluating the effects of complementary therapies in people with multiple sclerosis (pwMS). We sought to identify the outcomes most relevant to pwMS, their relatives and friends, healthcare professionals and researchers and to propose these for inclusion in future trials.

Design

A participatory international research project using a mixed-method approach with qualitative and quantitative methods. The study included a scoping review and a national survey in Switzerland to identify candidate outcomes, followed by an international COS survey to rate the importance of these outcomes. The final phases involved two consensus meetings to refine and finalise the COS.

Setting

Data were sourced from the published literature and input from international stakeholders.

Participants

pwMS and other relevant stakeholders, including their relatives and friends, healthcare professionals and researchers.

Results

A total of 770 individuals participated in the international COS survey of 39 candidate outcomes (662 pwMS, 27 relatives/friends, 58 healthcare professionals and 23 researchers). According to the survey results, 13 outcomes were added to the COS, 5 were excluded and 21 were classified as ‘no consensus’. 13 individuals (six pwMS, one pwMS’s friend, three healthcare professionals and three researchers) attended the first consensus meeting. Following the voting on the outcomes without consensus, seven outcomes were added to the COS, four were excluded and 10 outcomes were still classified as ‘no consensus’. The six members of the stakeholders advisory board (one pwMS, four healthcare professionals and two researchers) attended the second consensus meeting to define the final COS. Nine additional outcomes were included in the COS. Sexual problems, an outcome previously excluded, were also added. In total, 30 outcomes were included in the final COS.

Conclusion

We have developed the first COS for future trials of complementary therapies for pwMS. The use of this COS will promote that future research in complementary therapies is relevant for pwMS and other stakeholders involved in MS care. Future COS research should integrate diverse geographical regions, where perspectives and access to complementary therapies may vary.

Effect of nature-based health interventions for individuals diagnosed with anxiety, depression and/or experiencing stress--a systematic review and meta-analysis

Por: Jessen · N. H. · Lovschall · C. · Skejo · S. D. · Madsen · L. S. S. · Corazon · S. S. · Maribo · T. · Poulsen · D. V.
Objectives

The use of natural environments and nature activities as elements in the treatment and rehabilitation of mental health challenges is gaining international attention. The objective of the present review was to summarise the knowledge on the effects of nature-based health interventions (NBHIs) targeting individuals diagnosed with anxiety, depression and/or experiencing stress.

Design

Systematic review and meta-analyses. The quality and certainty of evidence were assessed using the SIGN and GRADE.

Data sources

Searches were performed in Embase, MEDLINE, PsycINFO, CINAHL, Cochrane and Web of Science.

Eligibility criteria

(1) NBHIs, (2) Individuals with a diagnosis of mild to moderate anxiety, depression and/or experiencing stress, (3) Age of participating individuals: 18–84 years, (4) Study designs: randomised controlled trials, cohort studies, case-control studies and case-series studies and (5) Publication date: 2000–2024.

Data extraction and synthesis

Screening, quality appraisal and certainty of evidence, assessed using SIGN and GRADE, were performed by two independent reviewers, except title screening. Meta-analyses were performed using random-effect models.

Results

Nineteen articles were included, of which 14 were included in the meta-analyses. The articles showed substantial variation in design, interventions, settings and risk of bias, limiting the certainty of evidence according to GRADE. Participating in NBHIs led to a small to large effect in mental health with standardised mean changes of –0.80 (95% CI= (–1.56; –0.04)), –0.87 (95% CI= (–1.18; –0.56)), –0.32 (95% CI= (–0.74; 0.09)) and 0.58 (95% CI= (0.39; 0.77)) for anxiety, depression and stress scores and overall mental health scores, respectively.

Conclusions

This is the first systematic review examining the effect of NBHIs exclusively on individuals diagnosed with anxiety, depression and/or experiencing stress. Our findings suggest small to large improvements after participating in NBHIs. However, methodological limitations to the included articles necessitate cautious interpretation.

Objectives

COVID-19 in children is generally of short duration, but some may take longer to recover. This study investigated the time to symptom resolution following SARS-CoV-2 infection among children in a community setting on the outskirts of an urban centre in Brazil.

Design

Prospective cohort study.

Setting

This is a community-based cohort of children living in Manguinhos, a favela in Rio de Janeiro. The cohort was followed through home visits and telephone monitoring of symptoms. The analysis focused on symptomatic children from this cohort with confirmed SARS-CoV-2 infection. Recovery time was defined as the interval between the first date with symptoms and the first date without symptoms following a positive SARS-CoV-2 test.

Participants

A total of 1276 children (boys and girls aged 2–

Outcome measure

COVID-19 recovery time, assessed based on change points on the symptom persistence probability curve (Kaplan-Meier).

Results

Among children who tested positive, 148 (60%) were symptomatic. The median recovery time was 11 days (IQR: 7–16). Two inflection points were identified on the Kaplan-Meier curve: days 16 and 34. Children who were ill during the Omicron wave took longer to recover. More boys became asymptomatic within the first 15 days; about 93% of girls recovered by day 33, and boys were more common among those who recovered in ≥34 days. Children aged 6–

Conclusions

Among children from a vulnerable area in Rio de Janeiro, recovery time was longer than that reported in other countries, with 9.5% of children experiencing persistent symptoms for more than 33 days. These findings are crucial for understanding the implications of COVID-19 in specific socioeconomic contexts and the dynamics of paediatric recovery in community settings.
