Catering to patients with Parkinsons disease: a survey on self-perceived competence and barriers of speech and language pathologists in Malaysia

Por: Smith · G. · Kamarulzaman · N. B. · Siau · C. S. · Chu · S. Y. · Woo · P. J. · Zhang · M. M. · Yuen · M.-C. · Garraffa · M.
Objective

Referrals to speech and language pathology are infrequent for people with Parkinson’s disease (PD), despite speech and communication being often affected and greatly impacting their quality of life. This study investigated the knowledge, self-competence and challenges faced by speech and language pathologists (SLPs) in Malaysia when managing PD cases.

Design

Participants self-administered an online-survey in a cross-sectional study design. The survey consisted of 14 questions on current practices of SLPs with their patients with PD, self-perceived competence when assessing and managing PD and perceived barriers for catering to patients with PD. Inferential statistics were run on self-perceived competence across domains and their relationship with demographic/current practice factors. Descriptive statistics were used to analyse perceived barriers.

Setting

The survey was administered in English through Google Forms.

Participants

54 Malaysian SLPs with at least one active case of PD in their caseload were invited via email and WhatsApp Messenger. These contacts were obtained from the Speech-Language Therapists Association of Malaysia (SPEAK), and snowball sampling was encouraged to recruit additional SLPs through other social networks.

Primary and secondary outcome measures

To quantify Malaysian SLPs’ self-perceived competence levels (assessed on 5-point Likert scales) in assessing and managing five key domains in patients with PD: speech, language, oro-motor skills, cognition and swallowing; and to identify the frequency and types of barriers encountered in clinical practice with patients with PD through structured multiple-choice questions. Secondary outcomes included quantifying current service delivery patterns (frequency of PD referrals, stage at referral, caseload size), multidisciplinary consultation patterns and confidence levels in managing rehabilitation risks associated with PD, all measured through structured survey items with categorical or ordinal response options.

Results

Most participants had 1–5 patients with PD in their active caseload, referred at a middle or advanced stage of the disease. The majority of participants felt competent in assessing and managing motor speech and language in patients with PD. Conversely, most of them did not feel competent in assessing and managing cognition in these patients, regardless of demographic factors or current practices. This difference was significant. Most participants also reported facing barriers such as health conditions or comorbidities, family expectations on the therapy outcome and the unavailability of a multidisciplinary approach.

Conclusion

The study reveals that SLPs working in Malaysia feel competent in working with motor speech and language in individuals with PD. However, it highlights a need for additional training to address cognitive assessment and management as a crucial tool to boost functional communication in people with PD. The study also reveals a need for promoting a multidisciplinary approach.

School-based versus community-based interventions for promoting mental health among school-age children in marginalised or underserved populations: a systematic review protocol

Por: Oranye · N. O. · Dibaba · A. · Nwankwo · I. U. · Webb · L. · Lee · T. · Alexander · M. · Kagulire · J. · Landu-Adams · V. · Nnedum · O. A. · Abdalla · E. · Sodeke · S. · Underwood · J.
Introduction

School-aged children frequently experience psychological distress due to academic pressures, a challenge that is often more severe for those from underserved and minority communities. This study aims to evaluate the effectiveness of mental health interventions implemented in school and community settings for children aged 5 to 19. It also seeks to compare the outcomes between children from minority and underserved populations and their peers.

Methods and analysis

This systematic review will follow Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines to identify relevant studies. Major databases will be searched using a structured search strategy developed by the research team. The review will include randomised controlled trials (RCTs) that assess the impact of interventions conducted in school or community settings to prevent psychological distress—specifically depression, anxiety and stress. To minimise bias, two reviewers will independently select studies and extract data at various stages. The quality of included studies will be assessed. A meta-analysis will be conducted to compare intervention outcomes between children from underserved/minority communities and other children. Pooled prevalence rates and subgroup analyses will be used to explore differences in effectiveness. Heterogeneity among studies and publication bias will also be assessed. Meta-analyses of proportions, ORs and relative risks will be conducted using a random-effects model to estimate effect sizes from multivariate analyses.

Ethics and dissemination

Ethical approval was not required, as this study involved secondary analysis of published literature and did not involve human participants. To date, no systematic review has comprehensively compared school-based and community-based interventions in terms of their effectiveness in addressing anxiety, depression and stress among school-aged children. This review aims to fill that gap by providing clinical insights into the comparative effectiveness of various intervention types and settings.

Can digital self-screening improve identification of chronic dyspnoea in Australian general practice? A proof-of-concept protocol for the BREATHE SMART trial

Por: Jang · K. · Giskes · K. · Martin · A. · Sunjaya · A. P. · Khin · P. · Jenkins · C. · Hespe · C. M. · on behalf of the BREATHE SMART Steering Committee · Hespe · Jenkins · Martin (Humphries) · Giskes · Lowres · Woods · Chua · Pearce · Ben Freedman · Sunjaya · Fardy · Tam
Introduction

Chronic dyspnoea is a prevalent and clinically significant symptom, often indicative of underlying cardiorespiratory disease. It is frequently under-reported by patients and under-recognised in primary care, with these challenges exacerbated in rural and remote communities where disease burden is greater and patients experience barriers to timely diagnosis and management. The BREATHE SMART trial aims to implement and evaluate an innovative, fully digital self-screening system for chronic dyspnoea, integrated into general practice workflows and information technology infrastructure. This approach seeks to enhance early detection and management of chronic cardiorespiratory conditions across diverse practice settings.

Methods and analysis

This multisite proof-of-concept study will test a software platform delivering a preconsultation self-screening questionnaire across 40 general practices in urban, rural and remote Australia. The system identifies eligible patients (≥18 years, consenting to SMS communication with their practice), issues an automated SMS that administers a validated dyspnoea screening questionnaire, and summarises responses for integration into the electronic medical record. Process evaluation will assess acceptability and utility using deidentified audit data, software metrics and qualitative feedback from patients, staff and general practitioners (GPs) via surveys, interviews and focus groups. Approximately 12 000 patients will be screened over 12 months. Primary outcomes will include the proportion completing self-screening and prevalence of chronic dyspnoea and secondary outcomes will include the rate of newly diagnosed chronic dyspnoea-related conditions (ie, asthma, chronic obstructive pulmonary disease and heart failure) in the preceding 12 months and during the intervention period.

Ethics and dissemination

Ethics approval was granted by the University of New South Wales Human Research Ethics Committee (HREC) (iRECS6645) and the University of Notre Dame Australia HREC (2024-155). Participating practices and each GP will provide written, informed consent. All patients being screened will provide electronic informed consent. Results of the study will be disseminated through various forums, including peer-reviewed publications and presentation at national and international conferences. Following the study, participating practices will be provided with a summary of the findings of the study, together with a full copy of any publications and a plain language statement for participants, which will be made available in the practices.

TACKLE concussion study: an observational study of post-concussion biomarker and neuroimaging progression in adolescent male school sports-related concussion

Por: To · X. V. · Robinson · B. · Mitchell · G. · McDonald · W. · Cumming · P. · Wood · J. · Mammone · T. · Evans · T. · Ross · J. · Nasrallah · F.
Introduction

Sports-related concussion (SRC) is an established research topic in the context of sport professionals suffering from mild traumatic brain injury (mTBI), but there is scant investigation of SRC arising in school-aged athletes. Effective management of SRC in adolescents is especially dependent on obtaining an understanding of its pathophysiology and the multifaceted nature of recovery. In this planned observational study, we shall investigate the associations among multimodal data comprising blood-based and saliva-based biomarkers, diffusion tensor imaging (DTI), quantified susceptibility imaging (QSM), resting state functional connectivity MRI (rsfMRI) and cognitive testing in school rugby players with a conventional diagnosis of concussion. Our objective is to map out a natural history of the post-concussion injury and recovery process as measured by diverse biomarkers.

Methods and analysis

This prospective cohort study will enrol 450 male adolescents who participate in sports (including rugby, basketball and swimming). We shall quantify blood biomarker levels (total tau, neurofilament light, glial fibrillar acidic protein and ubiquitin C-terminal hydrolase-L1), white matter integrity on DTI, cerebral venous oxygen saturation on QSM, connectivity metrics on rsfMRI and cognitive performance after SRC. We conduct measurements at pre-injury baseline measure and post-SRC at four to five pivotal times: day 1 (day of injury), 3, 6, 13 and 21 (if symptoms persist) post-concussion. Using mixed-effects and trajectory modelling, we shall assess biomarker trajectories.

We have secured ethical approval for this study from The University of Queensland’s Human Research Ethics Committee, Queensland. We shall inform participants and/or their guardians verbally and in writing of the study’s scope and procedures as a condition for informed consent. The dissemination of findings shall entail peer-reviewed publications and presentations at national and international conferences and via research and clinical networks. Completion of this study should provide a clearer understanding of anatomic and functional outcomes in adolescents with sports-related concussion.

Benefits of the study

The multimodal investigation of a cohort of adolescents suffering from concussion in the context of community sports should offer broad insight into the effects of mTBI on the developing brain.

Measurement innovation for sensitive behaviours: applying direct and social network-based estimation approaches to intimate partner violence in Burkina Faso and the Democratic Republic of the Congo using cross-sectional data

Por: Thomas · H. L. · Bell · S. O. · Bazie · F. · Guiella · G. · Kayembe · D. M. · Akilimali · P. Z. · Decker · M. R. · Wood · S. N.
Objectives

To explore the feasibility of the confidante methodology to measure past-year intimate partner violence (IPV) experiences in Burkina Faso and the Democratic Republic of the Congo (DRC) through (1) comparison of direct assessment with indirect estimation via the confidante method and (2) assessment of the performance of each confidante method assumption.

Design

Cross-sectional study with nationally and subnationally representative data collected from December 2020 to March 2021 in Burkina Faso (national) and from December 2021 to April 2022 in Kinshasa and Kongo Central, DRC (subnational).

Setting

Burkina Faso; Kinshasa, DRC; Kongo Central, DRC.

Participants

Partnered women (married or cohabiting) aged 15–49 in Burkina Faso (N=3047), Kinshasa, DRC (N=702) and Kongo Central, DRC (N=688) and their partnered confidantes aged 15–49 (N=2064 in Burkina Faso, N=304 in Kinshasa, DRC, N=393 women in Kongo Central, DRC).

Primary and secondary outcome measures

Past-year IPV (emotional, physical, sexual, any) comparing differences in prevalence between the direct respondent sample and the indirect confidante sample, adjusting for confidante method assumptions.

Results

The confidante method produced comparable IPV estimates to respondents’ direct reports across sites (35.3% respondent vs 36.1% confidante in Kinshasa, DRC; 29.7% respondent vs 39.0% confidante in Kongo Central, DRC; 25.7% respondent vs 26.0% confidante in Burkina Faso, differences not statistically significant). Of note, there were differences in IPV estimates between respondents and confidantes by IPV subtype, with physical IPV consistently lower among respondents across sites and sexual IPV lower among confidantes in Kinshasa, DRC and Burkina Faso, though generally not statistically significant.

Conclusions

The confidante methodology did not afford advantages over standard, direct assessment for IPV. Overall, findings indicate the reliability of population-based surveys with direct IPV questions when implemented under recommended ethical guidelines, though direct reports are likely undercounts.

Screening for hyperglycaemia in pregnancy and pregnancy outcomes among Aboriginal women in remote communities of the Northern Territory, Australia: a retrospective cohort study

Por: Wood · A. J. · OHara · C. · Joyce-Tubb · A. · Webster · V. · Wicks · M. · Van Dokkum · P. · Maple-Brown · L. J. · Hare · M. J. L.
Background

Aboriginal women in the remote Northern Territory (NT) experience high rates of adverse pregnancy outcomes related to hyperglycaemia in pregnancy. Oral glucose tolerance test (OGTT) screening was recommended in early pregnancy but barriers to uptake exist.

Objectives

To examine uptake of screening for hyperglycaemia in pregnancy among Aboriginal women in remote NT communities and explore adverse pregnancy outcome rates among women who did not have early OGTT screening compared with women who did undergo screening in early pregnancy and those with pre-existing diabetes.

Design

Retrospective observational cohort study of pregnancies among Aboriginal women in remote NT clinics from January 2017 to December 2019. Screening for hyperglycaemia in pregnancy included having an early OGTT (

Results

Among 1191 pregnancies in 52 remote communities, pre-existing type 2 diabetes (T2D) was diagnosed in 6.4% (n=76) and gestational diabetes mellitus (GDM) was diagnosed in 13% (154/1191). Excluding women with pre-existing diabetes, 226 (20%) had an early OGTT. Guideline-directed screening (with either (a) an early OGTT diagnosing GDM or (b) a negative early OGTT followed by a routine OGTT) occurred in 14% of pregnancies (n=158). Compared with women who had an early pregnancy OGTT, the combined adverse pregnancy outcome was more common among women with pre-existing T2D (89% vs 54%, adjusted OR 6.06 (95% CI 2.75 to 13.35)) and similar among women who did not undergo early OGTT (50%, adjusted OR 0.97 (95% CI 0.71 to 1.32)).

Conclusion

Uptake of guideline-directed screening in Aboriginal women in remote NT was low, although there was no difference in pregnancy outcomes for women who were and were not screened with an early OGTT. Rates of adverse pregnancy outcomes were concerningly high in women with pre-existing T2D, highlighting a need to strengthen diabetes care for these women.

Measurement of quality of stroke care with national electronic health records: a prospective cohort study during and after the COVID-19 pandemic

Objectives

To evaluate the value of linked electronic health records (EHRs) for measuring stroke care quality in England before and after the COVID-19 pandemic, focusing on metrics not routinely captured: stroke incidence, dispensing of secondary prevention medications and a proxy of disability—time spent at home after stroke (‘home-time’).

Design

Prospective cohort study using national linked datasets.

Setting

England-wide health data linkage including the Sentinel Stroke National Audit Programme (SSNAP), primary and secondary care, dispensed medications and mortality records, accessed via National Health Service (NHS) England’s Secure Data Environment.

Participants

425 675 adults with a first stroke between 1 January 2020 and 31 December 2023; data were available for 304 210 in primary care, 279 825 in hospital admissions, 220 470 in SSNAP and 59 465 in death records.

Main outcome measures

Annual stroke incidence; first-year medication dispensing rates for antiplatelets, anticoagulants, antihypertensives and lipid-lowering agents (with a 1-month washout period) and home-time at 180 days post stroke.

Results

Stroke ascertainment was highest when combining all sources, with 10.8% of non-fatal ischaemic strokes recorded exclusively in primary care and 19.4% of fatal strokes identified solely through death records. Standardised annual stroke incidence rose from 227.6 (95% CI 226.1 to 229.0) to 244.8 (95% CI 243.4 to 246.3) per 100 000 over the study period including the COVID-19 pandemic. During the COVID-19 lockdown, non-fatal stroke recordings decreased while stroke-related deaths rose, indicating that recording quality was sensitive to shifts in healthcare-seeking behaviour during the pandemic. Among people with ischaemic stroke, 89.1% received an antiplatelet or anticoagulant, 44.5% an antihypertensive and 80.5% a lipid-lowering therapy. For haemorrhagic stroke, these proportions were: for anticoagulants 13.5%, antiplatelets 13.2%, antihypertensives 46.6% and lipid lowering 41.1%. Medication dispensing for stroke prevention declined with increasing age and comorbidity, but varied little by ethnicity, region or pandemic period. Mean home-time within 180 days of stroke was 166.6 (95% CI 166.4 to 166) days, decreasing with greater age (141.4 days for 90 years or older (95% CI 140.7 to 142.1)), deprivation (166.4 days (95% CI 166.1 to 166.6) for most deprived quintile) and stroke severity (137.4 days for National Institutes of Health Stroke Scale (NIHSS) score on arrival over 22 (95% CI 135.8 to 139.1)) and increasing with years from the COVID-19 pandemic 2023 (169.3 days (95% CI 169.0 to 169.5) vs 2020 164.4 days (95% CI 164.1 to 164.7)).

Conclusions

Standardised stroke incidence increased significantly over the study period, highlighting a growing public health burden that persisted despite disruptions due to the pandemic although variation in case ascertainment and stroke coding practices was observed. While secondary prevention coverage for antiplatelets and lipids was high, lower rates of dispensing of antihypertensives, particularly in older and comorbid populations, potentially signal a target for improvement. Home-time represents a sensitive, person-centred outcome that exposes disparities linked to socioeconomic deprivation and clinical severity that can be used to enhance routine stroke audits. These findings justify the expansion of linked EHR infrastructure and the modernisation of governance frameworks to enable the longitudinal evaluation of care quality beyond the COVID-19 era.

Cancer survival and its social determinants among children with a migrant background: systematic review protocol

Por: Rajabzadeh · V. · Sami · A. · Harila · A. H. · Richards · D. A. · Woodford · J. · von Essen · L.
Introduction

Childhood cancer survival rates are not equal for all, with disparities existing both between and within low- and middle-income countries and high-income countries, particularly among ethnic minorities and children with migrant backgrounds. Factors such as cultural misunderstandings, language barriers and limited support networks can lead to delays in diagnosis and treatment challenges, which can result in poor health outcomes. Social determinants of health (SDoH), such as housing insecurity and poverty, may worsen these disparities. This protocol outlines a systematic review to examine childhood cancer survival in children with migrant backgrounds compared with non-migrants and to explore the SDoH associated with these survival outcomes.

Methods and analysis

We will search MEDLINE (PubMed), Scopus, Web of Science, and Embase for relevant studies, with secondary searches of grey literature. Two reviewers will screen for observational studies, including longitudinal cohort, case–control, cross-sectional and registry-based studies, that report childhood cancer survival outcomes (eg, survival rates, HRs) for both migrant and non-migrant populations. A narrative synthesis will explore SDoH and their association with survival outcomes. If data allow, we will perform random-effects meta-analyses to estimate pooled survival outcomes. Subgroup analyses will examine factors such as geographic region, migration status and type of cancer.

Discussion

Understanding factors contributing to childhood cancer survival disparities in migrant populations is critical for informing the development of targeted strategies to address them, ensuring all children, regardless of their migration status, have an equitable opportunity for effective care and improved outcomes.

Ethics and dissemination

Ethical approval is not required for this study as it is based on previously published data and does not involve primary data collection. We will publish the results in peer-reviewed journals and present at academic conferences.

Development of a Loop-Mediated Isothermal Amplification (LAMP) for the screening of <i>Candida auris</i>

by Woong Sik Jang, Young Lan Choe, Soo Young Yoon, Chae Seung Lim, Min-Chul Cho

Background

Candida auris is an emerging multidrug-resistant yeast associated with invasive infections, healthcare-associated outbreaks, and high mortality, and is often misidentified by conventional diagnostic methods. Rapid, accurate, and scalable screening tools are essential for effective infection control, particularly in high-risk settings.

Materials and methods

We developed a multiplex loop-mediated isothermal amplification (LAMP) assay that combines a broad-range Candida Pan target with a C. auris–specific target in a single isothermal reaction. Assay conditions were optimized for primer ratio and temperature, and analytical sensitivity was evaluated using serial dilutions of culture-derived C. albicans and C. auris DNA, as well as contrived specimens consisting of urine, swab, and whole-blood matrices. Clinical performance was assessed using 35 Candida-positive clinical specimens (blood, urine, ear swabs) and 94 non-infectious controls. Results were compared with Candida Pan qPCR and C. auris qPCR. Cross-reactivity was tested against common bacterial isolates.

Results

Under optimized conditions (1:1 primer ratio, 64 °C), the assay allowed species-level discrimination, with C. auris positive for both Pan and auris channels and C. albicans positive only for the Pan channel. The C. auris-specific LAMP probe detected approximately 10²–10³ cells/mL in culture-derived and contrived specimens, showing a 1–2 log improvement over C. auris qPCR (10⁴–10⁵ cells/mL), while the Pan LAMP channel detected C. auris at around 10⁵ cells/mL. In clinical specimens, Pan LAMP detected Candida spp. in 34/35 cases (97.14%) versus 32/35 (91.14%) for Pan qPCR. All C. auris–positive specimens (9/9) were detected by the multiplex LAMP assay, compared with 6/9 (66.7%) by Pan qPCR. All 94 non-infectious controls and all bacterial isolates tested negative, indicating 100% clinical specificity and absence of cross-reactivity.

Conclusion

The multiplex Candida Pan/auris LAMP assay provides a rapid, highly sensitive, and specific alternative to qPCR for C. auris screening, while preserving broad Candida detection in a single isothermal reaction. Its improved analytical and clinical sensitivity suggests strong potential for use in active surveillance and infection-control programs, particularly in settings where timely identification and containment of C. auris are critical.

Seasonal and temporal trends in leading causes of hospitalisation among older adults in Hong Kong: a retrospective study across community and institutional care settings

Por: Qian · X. X. · Chau · P. H. · Lai · E. T. C. · Wong · G. L.-H. · Woo · J.
Objectives

With an ageing population, understanding leading causes of hospitalisation in older adults is critical for care strategies. These leading causes may vary across residential settings and by seasonal patterns. This study examines the temporal trends of leading causes of hospitalisation among older adults in community-dwelling and nursing home settings, specifically comparing patterns during winter and summer seasons.

Design, setting, participants and main outcome measures

A retrospective analysis of electronic medical records from Hong Kong public hospitals (2012–2018) was conducted for three million adults aged ≥65. Age-standardised and sex-standardised monthly hospitalisation rates and average annual percentage change (AAPC, representing the average yearly percentage change in rates) were examined for leading causes during summer and winter across settings.

Results

Among community-dwelling individuals, the top five causes in 2018 were symptoms, signs and abnormalities not classified elsewhere (NEC), neoplasms, genitourinary, circulatory and respiratory diseases in winter, with digestive diseases replacing respiratory diseases in summer. Symptoms, signs and abnormalities NEC (AAPC: 2.7% (95% CI 1.8% to 3.6%) in winter; 3.4% (2.8% to 4.0%) in summer), neoplasms (2.4% (1.4% to 3.4%) in winter; 2.5% (1.6% to 3.4%) in summer), genitourinary (2.5% (2.1% to 2.9%) in winter; 2.4% (1.8% to 3.0%) in summer) and digestive diseases (2.5% (1.6% to 3.3%) in winter; 2.6% (1.7% to 3.5%) in summer) increased, while circulatory diseases decreased in winter. In nursing home residents, the top five causes in 2018 were respiratory diseases, symptoms, signs and abnormalities NEC, genitourinary, circulatory and digestive diseases in winter and summer. Symptoms, signs and abnormalities NEC increased (2.9% (0.9% to 5.0%) in winter; 2.9% (0.8% to 5.1%) in summer), while circulatory diseases declined across seasons. Genitourinary diseases remained stable across seasons, whereas digestive diseases declined in winter.

Conclusions

In Hong Kong’s ageing population, seasonal and temporal shifts in hospitalisation causes were observed. Symptoms, signs and abnormalities NEC emerged as the top two causes across settings, highlighting challenges for primary care and hospital management and need for enhanced prevention and care strategies.

Utilisation of brain MRI for the diagnosis of dementia in low and middle-income countries: systematic review and meta-analysis

Por: Nassanga · R. · Nakasujja · N. · Mubuuke · A. G. · Lwere · K. · Kawooya · M. G. · Ocan · M. · Kaddumukasa · M.
Objectives

To synthesise the prevalence and patterns of dementia-relevant structural brain MRI abnormalities in adults with suspected or confirmed dementia in low- and middle-income countries (LMICs), and to summarise MRI protocols and the incremental diagnostic contribution of MRI beyond cognitive screening.

Design

Systematic review and meta-analysis.

Data sources

PubMed, EMBASE, Web of Science and PsycINFO (January 1990–27 January 2025), plus reference list screening and targeted manual searches.

Eligibility criteria

Observational or diagnostic-accuracy studies from World Bank-defined LMICs including adults (≥50 years) with suspected or confirmed dementia who underwent brain MRI as part of diagnostic evaluation.

Data extraction and synthesis

Two reviewers independently screened, extracted data and assessed risk of bias using ROBINS-I. Random-effects models pooled prevalence of dementia-relevant MRI abnormalities; diagnostic-accuracy outcomes were synthesised narratively due to heterogeneous reference standards and incomplete reporting.

Results

39 LMIC studies were included; 23 studies (2513 participants) contributed to the meta-analysis. Dementia-relevant MRI abnormalities (defined as ≥1 clinically relevant structural abnormality per study definition) were present in 1248/2513 participants. The pooled prevalence of dementia-relevant MRI abnormalities was 58% (95% CI 43% to 72%), with substantial heterogeneity (I²=95%) and a wide prediction interval (8–96%), indicating marked between-study variability; this estimate should be interpreted as a descriptive summary of study-level proportions rather than a precise population parameter.

Conclusions

Brain MRI frequently demonstrates dementia-relevant pathology in LMIC clinical cohorts, usually with mixed neurodegenerative-vascular patterns. Structured visual ratings may add aetiologic specificity beyond cognitive screening, but pooled estimates should be interpreted as summaries of heterogeneous study-level findings rather than precise population parameters, given high heterogeneity and risk of bias.

An overlooked source of skin dose perturbation: Commercial tattoo inks in radiotherapy

by Hongjun Park, Beechui Koo, Jungwook Shin, Byoung Hyuck Kim, James J. Sohn

Approximately one-third of US adults have tattoos, yet the dosimetric impact of intradermal tattoo pigments during radiation therapy remains uncharacterized. Commercial tattoo inks contain unregulated metallic impurities including chromium, lead, and nickel, raising concerns about dose perturbations in tattooed skin. This work quantifies radiation dose perturbations induced by high-atomic-number (Z) tattoo pigments under clinically relevant radiotherapy conditions. Monte Carlo simulations (TOPAS) modeled layered skin phantoms with a 0.3-mm intradermal tattoo layer embedded at 1.25–1.55 mm depth. Three commercial inks were evaluated: carbon-based (black) and metal-containing (Fe-rich brown, Al-containing orange) at pigment loadings of 5–100 vol% within the tattoo layer, to establish upper-bound effects. Electron (6, 18 MeV) and photon (6, 18 MV) beams were simulated with standard clinical geometry (1 × 1 cm² field, SSD = 100 cm). Photon irradiation produced pronounced, depth-localized dose enhancement, with peak dose enhancement factor (DEF) reaching 2.5 for brown ink at 18 MV, a 62% mean increase relative to non-tattooed skin driven by high-Z–mediated secondary electron production. Electron beams exhibited energy-dependent behavior: 6 MeV produced modest enhancement (peak DEF ~ 1.07), while 18 MeV unexpectedly generated dose deficits (DEF 

Enhanced Wound Healing Through Air‐Break Augmentation of Hyperbaric Oxygen Therapy Combined With Adipose‐Derived Stromal Cell Transplantation in a Murine Model

ABSTRACT

Hyperbaric oxygen therapy (HBOT) enhances wound healing by promoting angiogenesis and reducing hypoxia. However, the role of air-breaks—intermittent exposures to ambient air during HBOT—remains unclear. We investigated the effects of air-breaks on HBOT-mediated wound healing, particularly in combination with adipose-derived stromal cells (ASCs). Full-thickness wounds were created in C57BL/6 mice (n = 36) and assigned to control, HBOT (1 h/day, 2 ATA for 11 days), or HBOT with a 10-min air-break groups. In a second experiment, we evaluated ASC treatment combined with HBOT and air-breaks. Wound healing was assessed via gross examination, histology and gene expression analysis of collagen type 1 alpha 1 (Col1a1), hypoxia-inducible factor 1 alpha (Hif1a) and tumour necrosis factor (Tnf-α). Compared with HBOT alone, air-breaks significantly improved wound closure, epithelial regeneration and collagen deposition (p < 0.05). Gene analysis showed higher Col1a1 expression and lower Hif1a and Tnf-α levels in the air-break group. In ASC-treated wounds, air-breaks further accelerated healing, enhancing collagen synthesis and reducing hypoxia and inflammation. These findings suggest that incorporating air-breaks into HBOT protocols improves wound healing outcomes, both generally and in ASC-based therapies, by modulating collagen production, hypoxia and inflammation, and could optimise HBOT efficacy, particularly in cell-based regenerative therapies.

Prescribing Practices and Behaviours of Advanced Practice Nurses and Pharmacists: A Nationwide Cross‐Sectional Survey

ABSTRACT

Aim

To explore the prescribing practices and behaviours of Advanced Practice Nurses (APN) and pharmacist prescribers in Singapore, assess their confidence in key prescribing competencies, examine their use of information sources, and understand their views on the consequences of prescribing errors.

Design

Cross-sectional national survey.

Methods

A census survey of all registered APN and pharmacist prescribers in Singapore was conducted from February to May 2024 using a validated 96-item instrument. The survey assessed prescribing practices, confidence in prescribing competencies, use of information sources, and prescribing safety. Descriptive statistics were used for analysis.

Results

Ninety-one prescribers (54 APNs, 37 pharmacists) responded (32% response rate), most of whom worked in public medical/surgical settings. Prescribing comprised a median of 75% of their practice. Most time was spent prescribing continued medications, with less on initiating new medicines. Participants reported high confidence in communication, therapeutic partnerships, and working within professional standards. Greatest confidence was seen in educating patients, legal prescribing, and monitoring treatment response. Lower confidence was noted in complementary medicine-related tasks. Professional literature and colleagues were the most valued information sources. Most participants acknowledged the serious consequences of prescribing errors, though many believed such errors would likely be intercepted.

Conclusion

APNs and pharmacists demonstrate strong competencies in safe, holistic prescribing. However, cultural factors may limit patient engagement, highlighting the need to strengthen shared decision-making and collaborative practice.

Implications for the Profession

Refining governance structures, adopting tiered prescriber autonomy, and enhancing training in complex prescribing are essential. Standardising deprescribing, improving access to decision-support tools, and promoting interprofessional collaboration and patient involvement can strengthen care quality and team-based delivery.

Impact

This study offers the first national insight into Singapore's Collaborative Prescribing Framework and informs training, policy, and workforce development for non-physician prescribers locally and in similar international contexts.

Introduction

A neglected area of patient safety research is how the characteristics of mental health staff and teams may influence incidents, specifically, through unintended and harmful consequences of clinical care. While the research literature into patient safety has increased, there is still a need to further consider safety on mental health wards, for example, the role of the staff team in containment and conflict. This review aims to explore the question, ‘How do staff and team characteristics relate to safety incidents in adult inpatient mental health settings?’.

Methods and analysis

The review will follow Whittemore and Knafl’s integrative review framework. CINAHL, Cochrane, Embase, MEDLINE, PsycINFO, Web of Science will be searched. Literature published after 1999, that includes extractable quantitative, qualitative and mixed methods data exploring the relationship between staff and team characteristics on incidents in adult inpatient mental health settings, will be suitable for inclusion. The Mixed Methods Appraisal Tool will be used for quality appraisal and data analysis and will comprise data reduction, display and comparison.

Ethics and dissemination

No new data or access to participants will be involved in this review. As such, ethical review will not be required. Dissemination will include publication in peer-reviewed journals and presentations at national and international conferences.

Introduction

Newborn bloodspot screening (NBS) is freely and universally available to babies born in Australia, with nearly 300 000 newborns screened each year. The NBS programme screens for approximately 30 conditions; however, there are hundreds of childhood conditions that could be treated if identified earlier and asymptomatically. Contemporary screening platforms have relied on mass spectrometry-based technologies, limiting surveillance to conditions with validated biomarkers detectable within the neonatal period. Advancements in metabolic techniques and genomics have expanded the range of conditions that could be detected. The NewbornsInSA research study will develop, validate and evaluate a novel multi-omic model of newborn screening, integrating metabolomic and genomic newborn screening as complementary methodologies.

Methods

Parents can opt in to additional NBS through NewbornsInSA during pregnancy or shortly after birth. One thousand prospectively recruited families will be offered genomic NBS by whole-genome sequencing, including analysis of a virtual gene panel of over 600 genes, and concurrent metabolomic screening. Clinically actionable pathogenic or likely pathogenic genetic variants will be reported to parents and whole genome sequencing data will be available on request for diagnostic reanalysis, if required later in life.

Acceptability of the NewbornsInSA programme will be evaluated through stakeholder engagement activities with healthcare professionals, members of the public and patient advocacy groups. Family experiences will be assessed using online surveys. The diagnostic yield, accuracy and the costs and consequences of the multi-omic NBS model will be assessed by comparison to standard-of-care NBS.

NewbornsInSA will investigate the acceptability, feasibility and cost-effectiveness of a multi-omic newborn screening model in a prospectively recruited South Australian population. We hypothesise that this approach will increase the number of conditions identified, reduce the time to diagnosis and facilitate earlier care with better outcomes for newborns with genetic conditions.

Ethics and dissemination

This research study has been ethically approved by the Women’s and Children’s Health Network Human Research Ethics Committee (2022/HRE00258 and 2023/HRE00236). Findings will be disseminated through peer-reviewed publication and conferences.

Introduction

Early-life socioeconomic status (SES) increases the risk of poor mental health outcomes in adulthood. However, the mechanistic pathways underlying this relationship remain poorly understood. While addressing socioeconomic inequalities remains a long-term goal, identifying specific mediating pathways could reveal more immediate opportunities for effective interventions.

Methods and analysis

Using linked administrative data from New South Wales, Australia (1990–2022), we will emulate a target trial examining the relationship between SES at birth and acute mental health admissions and presentations between the ages of 18 and 25 years. An interventional mediation analysis will be used to examine the effect of multiple mediating pathways, including education, housing stability, child protection contact, parental incarceration and justice system involvement, on the outcome. The analysis will estimate direct and indirect interventional effects, quantifying how much of the SES-mental health relationship could be modified by interventions on specific mediators.

Ethics and dissemination

This study has received ethics approval from the University of Newcastle (H-2024-0015) and Aboriginal Health and Medical Research Council (2265/24) Human Research Ethics Committees. All dissemination activities will be conducted in accordance with data access agreements and following approval from all relevant data custodians (New South Wales Health System Data Services). Key findings will be communicated to relevant government agencies and policymakers through policy briefs and stakeholder meetings, and publication in appropriate academic journals.

Tonsil-derived mesenchymal stem cells alleviate skin inflammation by modulating neutrophil extracellular trap formation and T cell migration

by Hyun Ju Kim, Kyung-Ah Cho, So-Youn Woo

Skin inflammation arises from complex interactions among immune cells, particularly T cells and neutrophils. Mesenchymal stem cells (MSCs) exhibit potent immunomodulatory properties, but the specific roles of tonsil-derived MSCs (T-MSCs) in regulating neutrophil extracellular trap (NET) formation and cell death, as well as T cell migration in inflammatory skin conditions, remain poorly defined. In this study, the therapeutic effects and mechanisms of T-MSCs were investigated in a 2,4-dinitrochlorobenzene (DNCB)-induced skin inflammation model, with a focus on NET formation and T cell migration. T-MSCs were intravenously administered to mice with DNCB-induced skin inflammation; inflammation severity and immune cell dynamics were evaluated using histological analysis, flow cytometry, immunostaining, microarray profiling, NET assays, and T cell migration assays. T-MSC treatment reduced DNCB-induced skin inflammation, as demonstrated by decreased epidermal thickness and neutrophil infiltration. Although T-MSCs enhanced NET formation in vitro, they suppressed neutrophil accumulation in vivo. T-MSCs also modulated the distribution and activation of T cell subsets in the skin and secondary lymphoid organs. Gene expression profiling revealed that T-MSCs regulated pathways associated with inflammation and neutrophil activity, including those involved in immune cell trafficking and NET formation. Moreover, T-MSCs promoted T cell migration, although this effect was influenced by neutrophil presence, indicating complex interplay among immune cells. These findings demonstrate that T-MSCs exert anti-inflammatory effects in DNCB-induced skin inflammation by modulating NET formation and T cell migration, revealing a novel immunoregulatory mechanism and supporting their therapeutic potential for inflammatory skin diseases.

Feasibility of the ICF CoreSets for Autism Strengths and Needs Assessment in NHS diagnostic services in England: protocol for a randomised pilot trial

Por: Day · M. · Scargill · K. · Poole · D. · Kellar · I. · Young · T. A. · Bölte · S. · Clarke · S. · Lodge · K.-M. · Woods · A. · Freeth · M.
Introduction

There are approximately 700 000 autistic people in the UK, and autism is increasingly being diagnosed in adulthood. Diagnosis on its own does not provide adequate information to plan post-diagnostic support for autistic people, and clinicians often plan support without the use of validated standardised tools which may exacerbate inequities in care. This study will evaluate a novel strengths and needs assessment, based on the WHO’s International Classification of Functioning, Disability and Health CoreSet for Autism, for use in adult diagnostic services immediately on receipt of an autism diagnosis. Potential issues, including the length of the assessment, timing of delivery and selection bias, will be explored as part of the trial process evaluation.

Methods and analysis

A two-arm, multisite, randomised pilot trial design will be used to evaluate the ICF CoreSets for Autism Strengths and Needs Assessment in three diagnostic services in England. A total of 72 newly diagnosed autistic adults will be recruited across the three sites over a 6-month period and randomised into an assessment group (strengths and needs assessment plus standard care) and a treatment as usual group (standard care only). The assessment group will receive a summary report of their strengths and needs on completion of the assessment. Both groups will complete measures of mental health and quality of life at baseline and 3 months follow-up (Patient Health Questionnaire-9, Generalised Anxiety Disorder questionnaire-7, Recovering Quality of Life questionnaire-10, EuroQoL-5D). Acceptability and feasibility will be measured for the strengths and needs assessment and for trial procedures using standardised measures, progression criteria and qualitative data from clinician focus groups and interviews with a subsample of autistic participants. The study design and procedures are being co-produced with an autistic advisor/patient and public involvement lead and with a steering group of autistic adults.

Ethics and dissemination

This study was reviewed by the East Midlands—Nottingham 2 Research Ethics Committee and was given Health Research Authority approval on 18 March 2025 (REC reference:25/EM/0041). The results will be disseminated via reports to the funder (NIHR), a peer-reviewed journal paper and academic conferences. We will email a summary report of findings to study participants and will invite participants to an information dissemination event at the end of the study.

The Barriers and Facilitators Healthcare Professionals' Experience When Assessing the Cutaneous Manifestations of Chronic Venous Insufficiency and Peripheral Arterial Disease in People With Dark Skin Tones: A Qualitative Descriptive Study

ABSTRACT

Recognising peripheral arterial disease and chronic venous insufficiency early and managing them appropriately improves patient outcomes and prevents ulceration. However, few studies consider the influence patient skin tone has on this assessment. The study aimed to explore the experiences of healthcare professionals when assessing the cutaneous manifestations of chronic venous insufficiency and peripheral arterial disease in people with dark skin tones. We conducted semi-structured online interviews with healthcare professionals working in the United Kingdom between July and December 2023. The ‘theoretical domains framework of behaviour change’ (TDF) guided the interview schedule and data analysis. 24 healthcare professionals were interviewed (18 nurses, 5 doctors, 1 physiotherapist) with an average experience of 15 years (IQR 9.75–21.75 years). We found the environmental context domain best explains clinical behaviour, which included effective teamworking, referral pathways and training, and adequate lighting. Environmental factors also influenced other aspects of the TDF such as skill development, focus and concentration, and belief about capabilities. Some participants also found personal challenges in asking questions exploring patients' behaviour and skin care practices as they did not want to cause offence. Findings will inform the development of interventions to support lower limb assessment in those with dark skin tones.
