Current applications of indocyanine green fluorescence angiography in trauma patients and its potential impact: a systematic review

Objectives
Tissue viability assessment is one of the main challenges in trauma surgery. Vitality assessment using indocyanine green fluorescence angiography (ICG-FA) may improve surgical decision-making. This systematic review gives an overview of current applications of ICG-FA in surgical treatment of traumatic injury and its effects on the incidence of postoperative complications and intraoperative decision-making.

Design
Systematic review according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.

Data sources
PubMed, EMBASE and MEDLINE were searched through 18 December 2023.

Eligibility criteria for selecting studies
Primary research reports regarding indocyanine green (ICG)-fluorescence in patients with traumatic injury were included. Exclusion criteria were use of ICG for treatment of burn wounds, traumatic brain injury or reconstructive surgery, absence of an English or Dutch full-text and non-primary study design.

Data extraction and synthesis
Two independent reviewers performed the search and screening process according to standardised methods. Risk of bias was assessed using the Methodological Index for Non-Randomised Studies. Data were presented in text and overview tables.

Results
Thirteen studies were included, of which six were case series/reports including three or fewer patients. Within the other seven studies, 301 patients received ICG-guided surgery. ICG was used for perfusion assessment in all studies. Injury types consisted of traumatic extremity and abdominal injury. All studies reported beneficial effects such as necrosis detection, determination of resection/debridement margins and reduction of debridement procedures. ICG could improve intraoperative decision-making and significantly decrease postoperative complications. No included studies reported ICG-related complications or adverse events.

Conclusion
The available literature regarding the use of ICG-FA in trauma surgery is limited, and comparability is low. Still, the results are promising and show a large potential of ICG-FA for better and more efficient treatment of trauma patients. Further research with larger samples and comparable conditions is thus necessary and highly recommended.

Targeting osteosarcopenia and multimorbidity for frailty prevention through identification and deep phenotyping methods in healthy ageing and high-burden disease cohorts (OPTIMA-C): a longitudinal observational cohort study protocol for neuromusculoskeletal muscle health

Introduction
Sarcopenia and frailty have been identified as negative predictors of health outcomes. Patients with stroke, traumatic brain injury (TBI), knee osteoarthritis (OA) and breast cancer commonly experience low physical activity levels in the chronic phase of recovery. This prospective study aims to explore the feasibility of multimodal screening and longitudinal tracking of various biomarkers from the acute to chronic phase of disease to determine the relationship with frailty outcomes.

Methods and analysis
A prospective longitudinal observational cohort study involving Asian populations is planned over 3 years. Enrolled participants with index conditions of acute stroke, TBI, knee OA and breast cancer will be recruited from rehabilitation hospitals and clinics and followed longitudinally. Reference thresholds from the Asian Working Group on Sarcopenia will be used. Variables include self-reported questionnaires, disease and comorbidity characteristics, anthropometric measurements, appetite questionnaires, muscle ultrasound (MUS), muscle/bone mass, blood biomarkers and markerless gait motion systems. In particular, physical performance (short physical performance battery and hand grip strength), sarcopenia (SARC-F questionnaire) and frailty assessment (FRAIL score, clinical frailty scale), four-region MUS, body composition analysis, dual X-ray absorptiometry, bone mineral densitometry, physical activity levels (International Physical Activity Questionnaire for the elderly [IPAQ-E], fitness trackers) and health-related quality of life assessment (EuroQoL-5D questionnaire five level [EQ5D-5L]) will be used. Blood biomarkers measuring metabolic health (eg, glycated haemoglobin, cholesterol, fasting glucose and 25-OH vitamin D) and inflammation (eg, Tumor Necrosis Factor-alpha [TNF-α] and Monocyte Chemoattractant Protein-1 [MCP-1]) will be measured at baseline. Data collection will take place at postrecruitment baseline (hospital admission), 1, 6 months, 12 months and 2 years postrecruitment (inpatient) and at postrecruitment baseline, 6 months, 12 months and 2 years postrecruitment (outpatient).

Ethics and dissemination
Ethical approval has been obtained from the National Healthcare Group Domain Specific Review Board (2023/00105). Findings will be disseminated through conference presentations and publication in scientific journals.

Trial registeration number
NCT06073106.

How do we measure dysarthria after stroke? A systematic review to guide the core outcome set for dysarthria

Objectives
A consensus study to establish a Core Outcome Set for dysarthria after stroke identified four key outcome domains that should be measured in research and clinical practice: (1) intelligibility of speech, (2) ability to participate in conversations, (3) living well with dysarthria and (4) communication partners skills and knowledge (where relevant). This review aimed to systematically identify corresponding measurement instruments and to examine their clinical utility and psychometric properties.

Design
Systematic review conducted in alignment with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.

Data sources
CINAHL, EMBASE, MEDLINE, PsycInfo and Cochrane Stroke Group Trials Register, CENTRAL, Linguistics and Language Behavioral Abstracts (LLBA). Major trials registers: WHO ICTRP, ISRCTN registry and ClinicalTrials.gov searched March 2024.

Eligibility criteria for selecting studies
We included trials that developed or used measurement instruments for poststroke dysarthria. We identified studies that could be included in an update of the Cochrane systematic review of interventions for non-progressive dysarthria to identify what measurement instruments were used in therapy trials for poststroke dysarthria.

Data extraction and synthesis
Records were screened independently by three authors. Psychometric data were extracted, by two authors, from included studies and methodological quality was evaluated using Consensus-based Standards for the selection of health Measurement Instruments (COSMIN) and Core Outcome Measures in Effectiveness Trials (COMET) guidance. Assessment of clinical utility followed Outcome Measures in Rheumatology (OMERACT) guidance.

Results
Following screening, 19 publications reporting 12 measurement instruments were identified. According to COSMIN standards, all 19 publications were rated as having low, very low or unknown quality of evidence. Three measurement instruments were identified as having the most relevant clinical utility to the population, the highest quality of evidence and had the potential to measure some specific aspects from three of the four agreed domains, intelligibility, conversations and living well with dysarthria from the patient and clinician perspective. These were the Frenchay Dysarthria Assessment II, the Communication Outcomes After Stroke Scale and the Therapy Outcome Measures for Dysarthria.

Conclusions
This review provides a comprehensive overview and appraisal of dysarthria measurement instruments to align with a Core Outcome Set. We only included English language-based measurement instruments. Many dysarthria measurement instruments were developed for non-stroke populations, including progressive dysarthria, with limited psychometric data for stroke. Measurement instruments with uncertain quality of evidence can still be considered for inclusion with a Core Outcome Set and three have been suggested. There is a need for further psychometric testing of these and the development of new measurement instruments to cover all aspects of intelligibility, conversations, living well with dysarthria and communication partner skills.

Proteomic Signatures for Risk Prediction of Atrial Fibrillation

Circulation, Ahead of Print. BACKGROUND:Proteomic signatures might improve disease prediction and enable targeted disease prevention and management. We explored whether a protein risk score derived from large-scale proteomics data improves risk prediction of atrial fibrillation (AF).METHODS:A total of 51 680 individuals with 1459 unique plasma protein measurements and without a history of AF were included from the UKB-PPP (UK Biobank Pharma Proteomics Project). A protein risk score was developed with lasso-penalized Cox regression from a random subset of 70% (36 176 individuals, 54.4% women, 2155 events) and was tested on the remaining 30% (15 504 individuals, 54.4% women, 910 events). The protein risk score was externally replicated with the ARIC study (Atherosclerosis Risk in Communities; 11 012 individuals, 54.8% women, 1260 events).RESULTS:The protein risk score formula developed from the UKB-PPP derivation set was composed of 165 unique plasma proteins, and 15 of them were associated with atrial remodeling. In the UKB-PPP test set, a 1-SD increase in protein risk score was associated with a hazard ratio of 2.20 (95% CI, 2.05–2.41) for incident AF. The C index for a model including CHARGE-AF (Cohorts for Heart and Aging Research in Genomic Epidemiology Atrial Fibrillation), NT-proBNP (N-terminal B-type natriuretic peptide), polygenic risk score, and protein risk score was 0.816 (95% CI, 0.802–0.829) compared with 0.771 (95% CI, 0.755–0.787) for a model including CHARGE-AF, NT-proBNP, and polygenic risk score (C-index change, 0.044 [95% CI, 0.039–0.055]). Protein risk score added to CHARGE-AF, NT-proBNP, and polygenic risk score resulted in a risk reclassification of 5.4% (95% CI, 2.9%–7.9%) with a 5-year risk threshold of 5%. In the decision curve, the predicted net benefit before and after the addition of protein risk score to a model including CHARGE-AF, NT-proBNP, and polygenic risk score was 3.8 and 5.4 per 1000 people, respectively, at a 5-year risk threshold of 5%. External replication of a protein risk score in the ARIC study showed consistent improvement in risk stratification of AF.CONCLUSIONS:Protein risk score derived from a single plasma sample improved risk prediction of AF. Further research using proteomic signatures in AF screening and prevention is needed.

Objectives
Hearing loss (HL) affects 20% of the world’s population, with shortages of audiologists and audiometric sound booths unable to meet demand for hearing care services. We aimed to assess the accuracy of tablet-based audiometry (TA) to screen for HL at standard (0.25–8 kHz) and extended high frequencies ( >8 kHz).

Design
Diagnostic accuracy study.

Setting
Two secondary care audiology and ear, nose and throat outpatient clinics in the UK between April 2022 and September 2023.

Participants
Adults aged≥16 years undergoing sound booth audiometry (SBA).

Interventions
TA, hearing-related questionnaires and patient usability questionnaires.

Outcome measures
Sensitivity, specificity and accuracy of TA compared with SBA for detecting HL. Patient usability assessment of TA and SBA.

Results
129 patients were enrolled with 127 patients (254 ears) included in the final analysis. Median age was 43 years (IQR 33–56), 55% (70/127) were women. 76% (96/127) and 68% (86/127) of patients had HL defined by British Society of Audiology (BSA) and American Speech–Language–Hearing Association (ASHA) criteria. Age was significantly associated with HL (p85%, respectively, between 0.25 and 12.5 kHz. In terms of patient usability, TA showed significantly higher scores in attractiveness (p

Current state of mental health research in Mozambique: a scoping review protocol

Introduction
Mental health is a fundamental component of overall well-being, underpinning our ability to make both individual and collective decisions. In Mozambique, estimates suggest that a significant number of Mozambicans suffer from common mental disorders such as depression and anxiety, yet the majority go undiagnosed and untreated. In recognition of this burden, the Mozambican Ministry of Health had approved the country’s first Mental Health Strategy and Action Plan in 2007, alongside the National Health Policy Mental Health Guidelines (2006–2015). However, the implementation of this plan and strategy has been challenged by a severely limited mental health workforce and fragile infrastructure. Despite these challenges, recent years have seen some progress, including multisite studies and international collaborations aiming to understand the burden of disease and improve services. Yet, the mental health literature in Mozambique remains fragmented, with significant gaps regarding specific population groups, barriers to care and the effectiveness of interventions. This fragmentation highlights the need for a comprehensive scoping review to map the current state of mental health research in the country and to guide future studies, policy development and clinical practice.

Methods and analysis
This scoping review aims to map the existing scientific literature on mental health in Mozambique over the past 15 years, focusing on study types, target populations, methodological approaches and key findings. Employing a two-stage screening process and both quantitative and a thematic synthesis approach, the review will analyse studies meeting predefined eligibility criteria. A rigorous search strategy will be implemented across identified electronic databases and grey literature sources, including published studies from 2009 to the present. Data will be charted using a standardised form, and information regarding study characteristics, scope of the research, population involved, geographic distribution and reported outcomes/findings will be collected. This scoping review will follow a standard protocol adhering to the methodological framework outlined by Arksey and O’Malley (2005).

Ethics and dissemination
Ethical considerations involve respecting original authors, maintaining integrity and transparency, managing data ethically and disclosing conflicts of interest. Dissemination will occur through publication in peer-reviewed journals, conference presentations, open-access repositories, policy briefs, stakeholder engagement activities and social media platforms.

Building rural health research capacity: protocol for a realist review

Introduction
While individuals living in rural areas often have poorer health outcomes and reduced access to healthcare services compared with those in urban areas, there is a disproportionate gap in research examining rural health issues and identifying solutions to healthcare challenges. This is likely due to the numerous barriers to conducting rural health research, including the centralisation of research in urban areas and limited trained personnel and resources to conduct research in rural communities. This realist review aims to identify articles focused on building rural health research capacity and develop an evidence-based framework to be used by researchers, clinicians and policymakers to improve rural health services and well-being for rural populations.

Methods and analysis
We will conduct a realist review using the following steps: (1) develop a search strategy, (2) conduct article screening and study selection, (3) perform data extraction, quality appraisal and synthesis, (4) engage stakeholders for feedback on our findings and (5) report our findings and engage in knowledge translation. Search terms include variations of the terms ‘research’, ‘capacity building’ and ‘rural’. Databases include (since inception) Ovid MEDLINE, Embase, CINAHL Plus, APA PsycINFO, ERIC and Scopus. A separate search of the same databases was also designed to identify relevant theories or frameworks related to research capacity building, using variations of the terms ‘research’, “‘capacity building’, ‘theory’ and ‘framework’. Studies will be screened by title and abstract and full text by two research team members and included based on their relevance to rural health research capacity building. We will exclude articles not published in English. We will also search the grey literature to identify rural health research centres, networks or training programmes that have not been described in the academic literature. Two research team members will extract relevant data from included studies and perform a qualitative analysis based on guidelines for realist reviews.

Ethics and dissemination
This review does not require ethical approval as it draws on secondary data that is publicly available. The findings will be disseminated at academic conferences, published in peer-reviewed journals and summarised in a lay report for individuals interested in developing strategies, programmes or policies to improve rural health research. The results will inform individuals developing rural health research training programmes, establishing rural research centres, or others interested in building rural health research capacity.

Assessing the association between drug use and ischaemic colitis: a retrospective pharmacovigilance study using FDA Adverse Event data

Objective
Drug-induced ischaemic colitis is a significant adverse event (AE) in clinical practice. This study aimed to recognise the top drugs associated with the risk of ischaemic colitis based on the FDA Adverse Event Reporting System (FAERS) database.

Design
A cross-sectional design.

Setting
All data retrieved from the FAERS database from the first quarter of 2004 to the fourth quarter of 2023.

Participants
A total of 5664 drug-induced ischaemic colitis AEs eligible for screening.

Primary and secondary outcome measures
The Medical Dictionary for Regulatory Activities was used to identify ischaemic colitis (code: 10009895) cases. Disproportionality analysis for drug-associated ischaemic colitis signals.

Results
Drug-induced ischaemic colitis AEs were more prevalent in females (60.12%) and individuals aged ≥65 years (34.25%). The common outcomes were hospitalisation (46.85%) and death (9.73%). Disproportionality analysis identified 91 ischaemic colitis signals and the top 30 drugs mainly involved in the gastrointestinal and nervous systems. The top five drugs with the highest reported OR, proportional reporting ratio, information component and the empirical Bayesian geometric mean, were alosetron, tegaserod, osmoprep, naratriptan and kayexalate. Additionally, 20 of the top 30 drugs did not have ischaemic colitis risk indicated in the package insert.

Conclusions
This study identified key drugs associated with ischaemic colitis, particularly alosetron, tegaserod, osmoprep, naratriptan and kayexalate. Notably, two-thirds of these drugs lacked ischaemic colitis warnings in their package inserts. These findings underscore the need for greater clinical vigilance, improved regulatory oversight and further research to clarify underlying mechanisms and support safer medication use.

Augmentation of trauma-focused psychotherapy for post-traumatic stress disorder: a protocol for a systematic review and meta-analysis

Introduction
Despite the established status of trauma-focused psychotherapy (TFP) as a first-line treatment for post-traumatic stress disorder (PTSD), a substantial proportion of individuals do not achieve clinically significant improvement or discontinue treatment. Exploring augmentation strategies to enhance treatment outcomes is essential to reduce the overall burden PTSD puts on individuals and society. This protocol outlines a systematic review and meta-analysis of randomised controlled trials (RCTs) evaluating the efficacy of non-pharmacological augmentation strategies in addition to TFP for PTSD treatment.

Methods and Analysis
We comprehensively searched PubMed, Embase, CENTRAL, PTSDpubs, PsycArticles, PsycINFO, PSYNDEX and CINAHL for RCTs without restrictions on publication dates or languages in October 2024. Study screening is currently ongoing. Additionally, we will perform forward and backward searches of the included studies and relevant reviews. Two reviewers will independently screen and select studies, extract data and assess the risk of bias. We will conduct a narrative review to qualitatively synthesise data and a meta-analysis to quantitatively compare the treatment efficacy of augmented TFP with TFP alone or TFP plus placebo. Primary outcomes will be both symptom severity and response rates. The secondary outcome will be dropout rates. We will explore sources of between-study heterogeneity and potential moderators through subgroup and meta-regression analyses. We will assess the overall quality of the included studies with the Grading of Recommendations Assessment, Development, and Evaluation system.

Ethics and dissemination
Ethical approval is not required. We intend to publish results in a peer-reviewed journal and provide materials and data through the Open Science Framework.
