Dialogic reading at age 2 is linked to frontal activation related to executive function at age 5: An fNIRS study

by Ming Yean Sia, Chia-Feng Lu, Ovid J. L. Tzeng, Shinmin Wang

This study investigates the relationship between children’s dialogic reading (DR) experiences with parents at age 2 and their frontal neural responses related to executive function (EF) at age 5. To assess how the intensity of DR influences brain development, we quantitatively measured parental engagement in DR when children are at 2 years of age. Neural activations in frontal regions associated with EF were evaluated using functional near-infrared spectroscopy when children reached age 5. Our results reveal a significant positive correlation between parental dialogic interaction during shared book reading at age 2 and the activation of key brain regions related to EF – the bilateral dorsolateral prefrontal cortex and the bilateral inferior frontal gyrus – during a Dimensional Change Card Sort (DCCS) task at age 5. This correlation persisted even after controlling for maternal education and children’s expressive vocabulary, indicating a robust relationship between early DR experiences and subsequent neural correlates of EF. The results suggest that early DR may help cultivate the neural infrastructure necessary for EF development. By focusing on DR at a young age and assessing neural activity during a classic EF task, the DCCS, our findings contribute additional evidence regarding the role of DR in shaping neural development associated with EF. These results highlight the importance of encouraging interactive DR practices in early childhood, as they not only support language development but also strengthen the neural pathways crucial for cognitive skills essential for academic success.

Multidisciplinary Offloading for Healed Diabetic Foot Ulcers: A Prospective Study on Functional Outcomes and Predictors of Recurrence, Amputation, and Mortality

ABSTRACT

To evaluate the effectiveness of multidisciplinary offloading versus standard care on one-year diabetic foot ulcer recurrence, amputation, mortality, and functional recovery. In this prospective cohort study, 232 patients with healed diabetic foot ulcers were stratified into a control group (76 patients) or an intervention group (156 patients) receiving offloading modalities ranging from felt padding to custom-made therapeutic footwear. Assignment was based on shared decision-making considering biomechanical needs and economic feasibility. Primary outcomes included recurrence, amputation, and mortality. Secondary outcomes assessed quality of life, working ability, and ankle function. The intervention group demonstrated significantly lower recurrence (10.9% vs. 25.0%; p = 0.007) and mortality (3.2% vs. 14.5%; p = 0.004). Multivariable analysis identified offloading as independently protective against recurrence (odds ratio 0.35) and mortality (odds ratio 0.24). Amputation rates did not differ significantly after adjustment. Functionally, the intervention group achieved superior recovery in quality of life, working ability, and ankle scores (p < 0.001). Subgroup analysis indicated that customized therapeutic footwear yielded the lowest complication rates and highest patient satisfaction. Multidisciplinary offloading significantly reduces recurrence and mortality while restoring physical function. Although financial barriers influence device selection, customized therapeutic footwear offers the optimal balance of biomechanical protection and functional outcomes.

Educational Attainment and Diabetic Foot Ulceration: Outcomes From the Barbados Diabetic Foot Study

ABSTRACT

Diabetic foot ulceration (DFU) contributes significantly to diabetes-related morbidity and amputation. In Barbados, where amputation rates are among the highest globally, the influence of socioeconomic factors on ulceration outcomes remains underexplored. Educational attainment, a social determinant of health, may influence health behaviours, engagement with healthcare services, and ultimately clinical outcomes. This study examines whether educational attainment is associated with diabetic foot ulcer severity, as measured by the SINBAD scoring system, and six-week healing outcomes among inpatients with DFU. A prospective observational study was conducted over 6 months at Barbados' sole public hospital. A total of 176 participants admitted with a diagnosis of DFU were recruited. Baseline demographics, comorbidities, and ulcer characteristics were collected, and SINBAD scores were determined. Random forest modelling was employed to evaluate predictors of complete healing at 6 weeks and to assess ulcer severity stratified by educational attainment. Of the cohort, 17.5% reported primary education as their highest attainment level, compared with 2.9% of the general adult population. The mean SINBAD score was 2.45 among those with primary education and 2.51 among those with secondary education (p > 0.05). No statistically significant association was found between educational attainment and healing outcomes at 6 weeks. Educational attainment in this inpatient DFU cohort was lower than that of the general Barbadian population; however, it was not significantly associated with ulcer severity or six-week healing outcomes. In a universal healthcare setting, equitable access to care may attenuate the effect of educational attainment on clinical outcomes. These null findings highlight the need for future adequately powered studies incorporating health literacy assessment and key clinical confounders. Nonetheless, the observed disparity in educational attainment among DFU inpatients suggests that foot health education initiatives should be designed to be accessible to individuals across all educational levels.

Reactive Nitrogen–Dominant Plasma Accelerates Diabetic Wound Healing Through Regulated Angiogenesis and TGF‐β Normalisation

ABSTRACT

Chronic diabetic wounds persist because of impaired angiogenesis, dysregulated transforming growth factor beta activity and delayed matrix remodelling. Non-thermal atmospheric pressure plasma therapy represents a potential non-pharmacologic approach to overcome these barriers. This study compared reactive nitrogen–dominant and reactive oxygen–dominant plasma exposures under identical apparatus conditions in a diabetic wound model. A universal plasma jet operated with nitrogen or argon gas was applied to streptozotocin-induced diabetic rats. Wound area reduction and time to 90% closure were quantified. Histological evaluation assessed re-epithelialisation and collagen deposition and immunohistochemistry measured angiogenesis using cluster of differentiation 31 staining and transforming growth factor beta expression. Nitrogen plasma treatment demonstrated sustained improvement in wound reduction relative to diabetic controls and reached 90% closure on day 19, whereas argon plasma reached this threshold on day 24 and diabetic controls exceeded 30 days. Nitrogen plasma was also associated with an earlier, self-limited angiogenic response characterised by an early cluster of differentiation 31 peak on day 6, together with patterns consistent with enhanced collagen maturation and earlier normalisation of transforming growth factor beta expression. Overall, these findings suggest mechanistic differences between reactive nitrogen–dominant and reactive oxygen–dominant plasma exposures in regulating angiogenesis and matrix remodelling during diabetic wound repair. These results indicate that plasma gas chemistry may influence wound-healing trajectories, supporting the potential of plasma therapy as a translational adjunct approach for difficult-to-heal wounds.

Who gets to deliver in a health facility? An investigation of wealth-based inequities in institutional delivery in Ghana

Por: Atta-Doku · J. F. · Achiam · W. K. A.
Objectives

Institutional delivery under skilled care is essential for reducing maternal mortality. Ghana has expanded maternal health services through policies such as the National Health Insurance Scheme and the free maternal healthcare policy. Inequalities in access to facility-based delivery, however, remain across socioeconomic groups. This study examined wealth-based inequities in institutional delivery and identified maternal and socioeconomic factors associated with facility delivery in Ghana.

Design

A cross-sectional analysis of nationally representative survey data.

Setting

Ghana.

Participants

Data were drawn from the 2022 Ghana Demographic and Health Survey. The analysis included 5855 women aged 15–49 years who had at least one live birth in the 5 years preceding the survey.

Methods

Descriptive statistics were used to summarise participant characteristics, and weighted logistic regression models were applied to identify factors associated with institutional delivery.

Results

84.3% of women delivered in a health facility. Wealth showed a strong gradient effect. Women in the richest wealth quintile had significantly higher odds of institutional delivery compared with those in the poorest quintile (odds ratio (OR) 2.71, p

Conclusion

Socioeconomic and geographic disparities in institutional delivery remain evident in Ghana. Wealth, education, antenatal care attendance and health insurance coverage influence access to facility-based childbirth. Targeted interventions are needed to improve equitable access to skilled delivery services.

Cancer loyalty card study-2 (CLOCS-2): protocol for an observational case-control study focusing on the patient interval in cancer diagnosis

Por: Toopchiani · S. · Codling · S. · Pondeca · Y. · Kaur · S. · Horeau · K. · Brewer · H. · Cross · A. · Delaney · B. · Faisal · A. A. · Peters · C. · Goulding · J. · Hirst · Y. · Sundar · S. · Flanagan · J. M.
Introduction

Some cancers are diagnosed late, making them harder to treat. People with an undiagnosed cancer may use over-the-counter medications to manage non-specific cancer-related symptoms that often mimic other more common, easily treatable conditions. Results from the original Cancer Loyalty Card Study (CLOCS) suggest there may be an increase in purchases of pain and indigestion medication 8–9 months before an ovarian cancer diagnosis. We aim to validate the CLOCS findings by exploring whether a significant change in medication purchases could be an indication for early signs of the following cancer types: oesophageal, stomach (gastric), colorectal (bowel), pancreatic, liver, bladder, endometrial, uterine sarcoma, ovarian and vulval, using data collected through store loyalty cards.

Methods and analysis

Using a retrospective case-control design, we aim to recruit 1450 participants with one of the cancers of interest (cases) and 1450 participants without cancer (controls) in the UK who (or whose household members) hold a loyalty card with at least one participating high street retailer. We will use pre-existing loyalty card data to compare past purchase patterns of cases with those of controls. To assess cancer risk in participants and their purchasing patterns, we will collect information on demographic characteristics, health risk factors, lifestyle habits and behaviours, family history of cancer and any symptoms experienced prior to diagnosis (cases) and in the last year prior to study recruitment (controls). In addition, cases will be asked about their cancer diagnosis.

Ethics and dissemination

CLOCS-2 was reviewed and approved by the East Midlands-Leicester South Research Ethics Committee (23/EM/0224). Study outcomes will be disseminated through peer-reviewed publications, conferences, presentations to the research communities as well as patients and the public, the study website and other social media outlets.

Sucralose inhibited cell survival through the activation of ER stress in human endothelial progenitor cells

by Chia-Ying Li, Hung-Yu Lin, En-Pei Isabel Chiang, Hung-Chang Hung, Feng-Yao Tang

Sucralose, a widely utilized non-caloric sweetener, is frequently added to food and beverage products as a sugar substitute aimed at lowering energy consumption and reducing obesity-related health risks. However, epidemiological studies have indicated a possible association between high intake of sucralose and increased prevalence of coronary artery disease (CAD). Prior research has demonstrated that diminished levels of circulating human endothelial progenitor cells (hEPCs) are linked to a higher risk of CAD. Although sucralose is broadly consumed, its direct biological impact on hEPCs has not been comprehensively characterized. In this study, we investigated the cellular effects of sucralose on hEPCs using a variety of in vitro techniques, including assays for viability, migration, capillary-like tube formation, lactate dehydrogenase (LDH) release-cytotoxicity assay, and protein expression profiling by Western blotting. Our results revealed that increased concentrations of sucralose significantly impaired hEPCs viability, motility, and neovasculogenic function, accompanied by increased expression of markers associated with apoptosis, inflammasome activation, and pyroptosis. Mechanistic analysis further demonstrated that sucralose strongly activated endoplasmic reticulum (ER) stress/PERK pathways in these cells. Inhibition of ER stress via 4-phenylbutyric acid (4-PBA) substantially attenuated sucralose-induced cell death and reduced the expression of pyroptosis-related proteins and inflammasome markers. Taken together, these findings suggest that sucralose disrupts hEPCs function in part by triggering ER stress, which promotes both apoptotic and pyroptotic cell death programs.

Protocol RCT for active informed consent in spine and urologic surgery in the metropolitan city of Bologna: does an increased patient engagement improve satisfaction of complex surgical procedures?

Por: Boriani · L. · Quattrini · I. · Maccaferri · B. · Lima · C. · Benuzzi · A. · Salvador · M. · Schiavina · R. · Brunocilla · E. · Deiure · F. · Maselli · V. · De Stefano · R. · Vommaro · F. · Gasbarrini · A.
Introduction

Informed consent is an essential component of surgical care; however, patients often struggle to fully understand procedures, associated risks and available alternatives. Factors such as preoperative anxiety, limited health literacy and the complexity of consent documents can further impair comprehension and information retention. The active informed consent (CIA) pathway, based on a Patient Educational Program that combines multimedia resources with a comprehension test, aims to enhance patient understanding, improve satisfaction and reduce medicolegal issues.

Methods and analysis

The study will be conducted as a multicentre, non-pharmacological, randomised controlled trial in three hospitals in the Emilia-Romagna region (Italy). A total of 300 patients undergoing elective complex spinal surgery or robotic radical prostatectomy will be enrolled and randomised (1:1) to the experimental arm or to the standard informed consent arm, using block randomisation stratified by centre. Outcomes will include patient satisfaction (Client Satisfaction Questionnaire), comprehension, psychological distress (Depression Anxiety Stress Scales), pain (Numeric Rating Scale), functional recovery (Oswestry Disability Index/International Prostate Symptom Score/International Consultation on Incontinence Questionnaire Short Form/International Index of Erectile Function) and medicolegal complaints. Assessments will be performed at baseline (T0), discharge (T1), 2 months (T2) and 6 months (T3), with extended monitoring of medicolegal outcomes for up to 5 years.

Ethics and dissemination

The study has been approved by the Regional Ethics Committee of Emilia-Romagna (protocol CIA21, V.1.3 dated 14 December 2022). Participation is voluntary and does not affect standard care. Results will be disseminated through peer-reviewed journals, conference presentations and communication with health authorities. If effective, the intervention may be implemented as a scalable model to improve patient empowerment and transparency in surgical consent.

Neoplastic Foot Ulcers: A Multicentre Retrospective Study

ABSTRACT

Neoplastic foot ulcers are particularly challenging for dermatologists and specialists in hard-to-heal wounds because their location and comorbidities can delay accurate diagnosis. We performed a multicentre, retrospective study analysing clinical and histological data, focusing on neoplastic foot ulcers collected over the past 5 years. We evaluated patients' demographic characteristics, clinical features, histological diagnosis, tumour onset and ulcer site. Statistical analyses were conducted using SPSS software, v.30. In total, 106 patients affected by foot skin ulcers were enrolled in the present protocol (52 women, 54 men). The mean age was 70.15 years. In most cases, the neoplastic ulcer was due to primary tumour ulceration. The dorsum of the foot was the most common site of neoplastic ulcers (66%). From a clinical perspective, most lesions were classified as ulcerated nodules (n = 58), ulcerated plaques (n = 8) or hypergranulating ulcers (n = 25), all with thickened, atypical edges. Histological diagnoses included melanoma (n = 45), non-melanoma skin cancers (n = 34), benign tumours (n = 18) and rarer malignancies (n = 9). A statistically significant correlation was found between histotype and clinical lesion type, and between age and histotype. The study provided preliminary data on the clinical and histological characteristics of neoplastic foot ulcers, warranting further exploration in a prospective, multicentre study.

Ecological momentary assessment of daily patient-reported outcomes and actigraphy-measured physical activity and sleep in patients with rheumatoid arthritis and spondyloarthritis: a study protocol

Por: Aymard · N. · Darmaillacq · A. · Bailly · S. · Kechichian · A. · Baillieul · S. · Bernardy · C. · Gastaldi · R. · Flore · P. · Baillet · A. · Mendelson · M.
Background

Rheumatoid arthritis (RA) and spondyloarthritis (SpA) are chronic inflammatory rheumatic diseases characterised by pain, fatigue, mood disturbances, sleep problems and reduced quality of life. These symptoms are highly variable both between individuals and within individuals across days, reflecting the fluctuating nature of disease activity and daily functioning. Although physical activity is known to alleviate many of these symptoms, individuals with RA and SpA often encounter barriers that limit regular engagement. Capturing the dynamic interplay between symptoms and physical activity therefore requires methods that account for day-to-day and moment-to-moment variability. Ecological momentary assessment (EMA), especially when combined with actigraphy, enables real-time, context-sensitive monitoring of symptoms and physical activity in daily life. However, little is known about the feasibility and acceptability of such protocols in individuals with RA and SpA, for whom participant burden and adherence may represent significant challenges. This pilot study therefore aims to assess the feasibility and acceptability of a 14-day EMA protocol and to explore factors associated with objectively measured physical activity in individuals with RA and SpA.

Methods and analysis

50 adults diagnosed with RA or SpA will be recruited through rheumatology clinics or via advertisement. Eligible participants must be smartphone users without cognitive or physical impairments affecting participation. After providing consent, participants will complete baseline questionnaires regarding disease activity, quality of life, sleep, pain, fatigue, affective states and will attend a remote session with a member of the research team to learn how to use the mobile app. They will then complete a 14-day EMA protocol, during which data on patient-related outcomes (PROs), including pain, fatigue, sleep quality and affective states (i.e. positive and negative affects) will be assessed four times daily: upon awakening, 11:00, 15:00 and 20:30. Physical activity and sleep will be continuously monitored using both a wrist-worn and a thigh-worn device. Feasibility will be evaluated based on adherence to EMA prompts and actigraphy wear time. Acceptability will be assessed via a study-specific questionnaire and qualitative interviews conducted at the end of the protocol. Exploratory analyses will examine real-time, temporal and lagged relationships between PROs (pain, fatigue affective states), sleep and physical activity levels.

Ethics and dissemination

This study was approved by the French national ethics committee [Comité de protection des personnes Nord Ouest I, 2025-A01349-40] on 24/07/2025. The results will be disseminated in peer-reviewed journals and at international conferences.

Understanding patient experience during Lokomat rehabilitation in children and adolescents: a clinical observational study combining self-evaluation and physiological metrics

Por: Chiappini · M. · Malerba · G. · Dei · C. · Bellazzecca · S. · Falivene · A. · Costantini · S. · Morganti · R. · Diella · E. · Storm · F. · Ambrosini · E. · Cavallo · A. · Biffi · E.
Objectives

To examine the emotional, cognitive and dispositional experience of children and adolescents undergoing Lokomat rehabilitation by integrating self-evaluation, therapist observations and physiological metrics across repeated sessions, with the aim of characterising how patient experience evolves throughout paediatric robot-assisted gait training.

Design

Prospective observational study using a multidimensional assessment approach combining self-report, therapist ratings and physiological measures.

Setting

Inpatients undergoing robot-assisted gait training (RAGT) with the Lokomat at the Scientific Institute Eugenio Medea in Bosisio Parini (Italy).

Participants

42 children and adolescents (N=42; mean age 11.66±5.59 years) undergoing RAGT.

Interventions

Robot-assisted gait therapy with the Lokomat. Participants underwent 30-minute therapy sessions as per routine rehabilitation protocols, with treatment durations ranging from 15 to 20 sessions, as prescribed by their referring clinician.

Primary and secondary outcome measures

Participants completed ad-hoc questionnaires about emotional, cognitive and dispositional factors before and after therapy; therapists provided structured assessments of patient engagement and psychological states. Physiological data, such as heart rate variability (HRV) and electrodermal activity (EDA), were recorded using wearable sensors to capture physiological correlates of emotional and cognitive engagement.

Results

The results showed that by the end of Lokomat therapy, patients displayed increased cognitive engagement and better emotional regulation, along with higher vagal activity (normalised high-frequency) and increased phasic EDA responses. According to the therapists, patients appeared more confident, calm and cooperative. Sympathetic activation observed during satisfaction ratings reflected the involvement of the autonomic nervous system in positive emotional experiences.

Conclusions

This study, therefore, emphasises a multidimensional approach to rehabilitation, which involves subjective patient self-assessments, therapist observations and physiological signals in an effort to capture a more comprehensive patient experience. The findings highlight the importance of personalised, patient-centred approaches and contribute new evidence on the psychological and physiological effects of RAGT in paediatric populations. Further research is warranted to confirm these results and explore their clinical implications.

Introduction

The surge in postsecondary students reporting mental health concerns, coupled with increased utilisation of on-campus and hospital-based mental healthcare, highlights a need to understand effective service navigation. To address this system gap, the University of Toronto and the Centre for Addiction and Mental Health (CAMH) leveraged their unique expertise and resources to develop the University of Toronto Navigation (UTN) service. UTN introduces care navigators to facilitate postsecondary student transitions from acute mental health services to community or campus mental healthcare. There has been limited implementation and evaluation of navigator models specific to the postsecondary context to date, which hinders scalability. This paper describes the study protocol of Navigation to Enhance Post-Secondary Students’ Acute Mental Health Care Transitions, a study that aims to collaborate with students, navigators and clinicians to evaluate the UTN service.

Methods and analysis

A one-stage, single-arm multimethods study design will be used to evaluate the UTN service. We will recruit 103 students following their UTN intake appointment. Students will complete quantitative measures assessing health outcomes, experiences of care and service utilisation at baseline and at three subsequent time points across a 6-month follow-up period. The quantitative data will be linked to administrative healthcare data. The primary evaluation outcome will be defined as attending an appointment with an appropriate care provider (in person or virtually) within 30 days of discharge from the hospital. We will conduct interviews with students and referring clinicians to gather perspectives regarding their experiences and satisfaction with the UTN service in greater depth.

Ethics and dissemination

Research ethics board approvals have been obtained from the University of Toronto and CAMH. Results will be disseminated through publications and presentations, and a toolkit will be cocreated to support implementation and adaptation of hospital-based navigator interventions in postsecondary contexts.

Effect of race and sex on lupus diagnosis in primary care: A randomized factorial survey study

by Alyssa Howren, Quan L. Tran, Sadaf Sediqi, Saadiya Hawa, Douglas K. Owens, Eleni Linos, Titilola O. Falasinnu, Yashaar Chaichian, Julia F. Simard

Background

Systemic lupus erythematosus (SLE) is a heterogeneous autoimmune rheumatic disease whose epidemiology and clinical prognosis vary by race and sex. Observed disparities in SLE may be partly attributable to cognitive processes in clinical decision-making, which can influence diagnostic accuracy and clinical management. We aimed to examine variation in primary care physicians’ (PCP) diagnosis and management of SLE when all content of a clinical case is identical, apart from race and sex.

Methods

We distributed an online randomized factorial survey from 04/11/2024–06/10/2024 to PCPs across the US. Participants were presented with one of four possible SLE vignettes – Black female, White female, Black male, White male – for which all other clinical content was identical. Block randomization was used to randomly modify the race (Black/White) and sex (female/male) of the SLE “case”. Primary outcomes were correct text-based responses for SLE diagnosis at initial case presentation and after reviewing additional lab results. Secondary outcomes were participants’ review time and planned next steps (treatment, referral, tests) as a proxy for cognitive bias and certainty, respectively. We calculated descriptive statistics for all outcomes stratified by assigned randomized factor and used chi-square tests to evaluate between-group differences.

Results

1031 PCPs (42.7% women, mean age 52.1 ± 12.1 years) completed the case. At initial presentation, 63.9% of participants correctly identified SLE as a differential diagnosis. An initial diagnosis of SLE significantly differed by the race and sex of the case (p  Conclusion

A patient’s race and sex may influence diagnostic accuracy and clinical decision-making for SLE in primary care. The observed variation in diagnostic accuracy, which aligns with the descriptive epidemiology of SLE, highlights the need for targeted interventions to ensure equitable diagnostic processes.

Extracts from <i>Cordyceps cicadae</i> and <i>Hericium erinaceus</i> promote the neurite outgrowth of retinal ganglion cells

by Fang-Yi Chen, Chin-Chu Chen, Chuan-Chin Chiao

The regenerative capacity of mammalian RGC neurites after damage, such as glaucoma, is limited. Numerous studies have utilized herbal extracts to promote neural regeneration and exert neuroprotective effects in the hope of mitigating glaucoma. In the present study, we investigated the effect of extracts from the cicada fungus (Cordyceps cicadae) and the Lion’s mane mushroom (Hericium erinaceus) on neurite outgrowth of retinal explants and isolated RGCs. We also examined whether these extracts affect the number of apoptotic cells and neurite outgrowth activity of RGCs. The results showed that an aqueous extract of Cordyceps cicadae, an ethanol extract of Hericium erinaceus, and the purified compound Erinacine Sare able to promote neurite outgrowth in retinal explants. Given its role as a key bioactive compound, Erinacine S was further investigated on isolated RGCs, where it also significantly enhanced neurite outgrowth, demonstrating a direct effect on RGC regeneration. In addition, these extracts have no significant drawbacks in terms of cell apoptosis and RGC neurite outgrowth activity at specific concentrations. The present study thus demonstrates that while excessively high concentrations of these extracts may inhibit neurite growth, at moderate concentrations some extracts from Cordyceps cicadae and Hericium erinaceus have the potential of promoting neurite regeneration in the mammalian retina. Further research targeting the molecular mechanisms behind these effects may shed light on their potential application as a medicine or nutraceutical for facilitating neural regeneration.

A pilot randomised controlled trial of a critical time intervention for people leaving prison: findings from an integrated process evaluation

Background

We conducted a pilot randomised controlled trial (the PHaCT study), including a process evaluation to assess the acceptability of a housing-led Critical Time Intervention (CTI) for prison leavers and the use of a trial design. This paper presents the process evaluation findings.

Objective

To explore the acceptability of both the intervention and the trial design to participants and those delivering the intervention, and to assess whether the intervention was delivered with fidelity.

Design

A process evaluation following Medical Research Council guidelines. Data collection included semi-structured interviews with participants and CTI caseworkers and observations of intervention delivery. A thematic analysis of interviews and observations was conducted to understand the intervention’s implementation and contextual factors as well as the trial process acceptability.

Setting

Participants for the pilot trial were recruited from three prisons in England and Wales where the intervention was being delivered.

Participants

While 28 out of 34 trial participants consented to interviews, only one was completed. Seven caseworkers were interviewed.

Intervention

A housing-led CTI to support people leaving prison at risk of homelessness, involving phased, time-limited support from caseworkers, starting prerelease and continuing postrelease, to help secure stable housing and build independence, without directly providing housing.

Results

The intervention’s acceptability was primarily reflected through the positive feedback and success stories shared by CTI caseworkers, as well as observational data indicating high acceptance among service users. The trial design’s acceptability was challenged by concerns about randomisation and equipoise, with staff viewing randomisation as unethical due to limited support for vulnerable populations. The fidelity to the CTI intervention housing-led approach was adhered to as best as possible; stable housing was prioritised for service users before addressing other needs. Despite these efforts, both sites encountered significant challenges due to limited housing availability and complex systems for securing social housing, particularly for single men leaving prison.

Conclusions

This wider study faced significant challenges which impacted the process evaluation. Despite these issues, the evaluation provides important insights into the challenges of conducting trials on interventions for people leaving prison. The challenges experienced should inform future study designs with similar populations and in similar settings.

Critical time intervention for people leaving prison at risk of homelessness in England and Wales (PHaCT trial): a pilot feasibility randomised controlled trial

Por: Williams · A. D. N. · Jacob · N. · Grozeva · D. · Lloyd · B. · Moriarty · Y. · Deidda · M. · Achiaw · S. O. · Thomas · I. · Lewis · K. · Cannings-John · R. · Madoc-Jones · I. · Fitzpatrick · S. · Katikireddi · S. V. · Mackie · P. · White · J. · Lewsey · J.
Objective

To determine whether a full-scale randomised control trial (RCT) assessing the efficacy and cost-effectiveness of a housing led Critical Time Intervention (CTI) is feasible and acceptable.

Design

Pilot parallel two-arm individual level RCT, including process evaluation and embedded exploratory health economic evaluation.

Setting

Four prisons for men across England and Wales, UK.

Participants

Men leaving prison at risk of homelessness and intervention delivery staff.

Intervention

CTI has four components: (1) pre-engagement phase: assessing the needs of the client and implementing a plan pre-discharge; (2) transition to community: forming relationships and goal setting; (3) try out: encouraging problem-solving and managing practical issues and (4) transfer of care: developing long-term goals and transferring responsibilities to community providers.

Outcome measures

Progression criteria: recruitment, retention, acceptability of the processes (CTI and trial method) and fidelity of intervention delivery. We also assessed the completeness of primary, secondary and exploratory outcome measures and estimated intervention costs.

Results

The recruitment progression criterion was met, with 92% (34/37) of approached individuals consenting to participate (target: 50%). However, the overall recruitment target of 80 was not achieved, and retention was low, only 18% (6/34) provided follow-up data, well below the 60% threshold. Retention was hindered by systemic challenges, including changes to prison release policies and reduced probation support. While the CTI model was acceptable to staff and service users, the trial design, particularly randomisation, was not. Intervention fidelity met the progression criteria. Baseline data collection for health economics and resource use was feasible, and intervention costs were estimated.

Conclusion

This pilot trial identified significant challenges to conducting a full-scale RCT of CTI in this context, particularly around retention, trial acceptability and systemic instability. While CTI remains a promising model, a traditional RCT design may not be viable in this setting without substantial structural and ethical adaptations.

Can creative activities and mind-body practices help enhance well-being and mental health awareness? An exploratory qualitative study in UK higher education

by Marianna Cortesi, Federico Pendenza, Elizabeth Haddon, Andrea Schiavio

Creative arts activities and mind-body practices, such as yoga, have been shown to benefit mental health and well-being. Research in higher education highlights the mental health challenges faced by students and staff in tertiary education; however, most studies on the potential of creative arts and mind-body practices have been conducted in the United States, with limited research investigating their impact in the UK higher education context. This qualitative study seeks to examine students’ and staff members’ views on extra-curricular creative and mind-body practices provided by one UK university, exploring how engagement in such activities can impact their understanding and awareness of mental health and well-being. In addition, it intends to investigate potential barriers to engagement with such activities. Drawing on questionnaire responses from 25 students and 20 staff members, findings highlight the effectiveness of art-based interventions and mind-body practices in raising awareness and understanding of mental health and well-being, while also having the potential to positively impact individuals’ mental health and well-being. Although personal interests and time restrictions may limit engagement, such activities were found to foster community-building, a particularly relevant factor in the post-Covid era, as institutions seek to re-engage students and staff through in-person activities. These findings have therefore important implications for the implementation of similar interventions in higher education and beyond to promote mental health and well-being awareness in diverse communities.

Objective

To examine the association between socioeconomic status (SES), financial subsidies and awareness-related factors such as age, cancer stage and family history, and the uptake of cancer genetic testing, with a focus on equitable access to care.

Design

Retrospective cohort study.

Setting

Tertiary care cancer genetics service in Singapore.

Participants

The study population included 2687 individuals of all ages, genders and ethnicities who attended pretest counselling between 2014 and 2020 and were eligible for genetic testing for hereditary cancer syndromes.

Primary and secondary outcome measures

The primary outcome was the uptake of genetic testing. The main explanatory variables were SES (proxied by Housing Index), subsidy status, age, cancer stage and family history. Analyses examined whether associations varied across SES and age subgroups.

Results

Receipt of financial subsidies was strongly associated with testing uptake (adjusted OR 9.15, 95% CI 2.68 to 31.20). Uptake exceeded 90% among subsidised individuals across all socioeconomic strata, compared with 56–68% among non-subsidised individuals, with the largest gains in the lowest SES group (43 vs 28 percentage points (pp) in the highest). The level of subsidy was not associated with uptake. Younger patients (18–39 years) had higher uptake than those aged 60+ (66% vs 57%); patients with advanced cancer (stage IV) had the highest uptake (82% vs 57–66% in earlier stages); and family history was associated with increased uptake, strongest for having a child with cancer (+28 pp). Interaction analysis suggested that the additive effects of subsidies were greatest in lower SES groups and in older adults.

Conclusions

Financial subsidies were strongly associated with higher genetic testing uptake. Awareness indicators like age, cancer stage and family history were associated with higher uptake. The association between subsidies and uptake varied by SES and age, suggesting that subsidies may help reduce disparities and improve equitable access to genetic testing services.

Non-smoking-related lung cancer is increasingly associated with environmental factors such as particulate matter (PM) exposure. Using deep small RNA sequencing, we identified distinct miRNA expression patterns in lung cancer patients compared to non-cancer controls, stratified by smoking status. Notably, hsa-miR-125b-5p and hsa-miR-100-5p were significantly downregulated in non-smoking lung cancer patients. Pathway enrichment analysis revealed smoking amplifies pathways related to glycan biosynthesis, signal transduction, and transcriptional regulation, while non-smoking lung cancer is characterized by immune dysfunction and metabolic alterations, including oxidative phosphorylation and natural killer cell cytotoxicity. Validation in a larger cohort using quantitative RT-PCR confirmed the suppression of miR-125b-5p and miR-100-5p in non-smoking lung cancer patients. Additionally, miR-203a and miR-199a-3p were identified as potential biomarkers for lung cancer, independent of smoking status. Chronic PM exposure in primary bronchial/tracheal epithelial cells initially elevated miR-125b-5p and miR-100-5p expression, but prolonged exposure suppressed these miRNAs while increasing their target genes, TXNRD1 and HOXA1, suggesting stress-induced dysregulation. Functional studies using miRNA mimics demonstrated that miR-125b-5p and miR-100-5p suppress PM-induced cancer cell mobility and colony formation, with miR-125b-5p exhibiting broader effects. These findings underscore the critical roles of miR-125b-5p and miR-100-5p in PM-associated lung cancer progression and their potential as biomarkers and therapeutic targets. This study highlights distinct mechanisms of lung carcinogenesis in smokers and non-smokers, providing a foundation for targeted interventions in PM-associated lung cancer.
