Self-treatment of benign symptoms using hot water bottles, steam inhalation or hot tea is common in households and poses risks of severe scald injuries. This study aims to investigate associated hazards and identify high-risk patient groups to facilitate targeted prevention. A retrospective, single-center descriptive study was conducted on adult burn patients with scald injuries from hot water bottles, steam inhalation or hot tea. Demographic information, injury mechanism and outcomes were analysed. A total of 43 patients (mean age: 37.5 years; female:male ratio 23:20) were included. Injuries were caused by hot water/tea (37.2%), steam (34.9%) and hot water bottles (27.9%). The average burned total body surface area (TBSA) was 4%, with 79.1% of injuries being superficial partial-thickness burns. Surgical intervention was required in 13.9% of cases. Hot water bottle injuries predominantly affected young females (75%, mean age 32.6 years), with a high incidence of genital burns (58.3%). Hot tea-related injuries were more frequent in older males (62.5%, mean age 41.6 years), involving greater TBSA (6.5%) and a higher necessity for skin grafting (18.8%). Common self-treatment strategies can cause serious scalds, particularly in specific demographic groups, thereby burdening healthcare systems. Awareness of these risks is pivotal for effective education and prevention.

Sternal surgical site infections after cardiac surgery can lead to significant morbidity, mortality, and cost. The effects of negative pressure wound management and adding vancomycin as perioperative antimicrobial prophylaxis are unknown. The PICS-PREVENA pilot/vanguard trial, a 2x2 factorial, open label, cluster-randomized crossover trial with 4 periods, was conducted at two major cardiac surgery hospitals in Ontario, Canada. Sites were randomized to one of eight sequences of the four study arms (Cefazolin or Cefazolin + Vancomycin (not analyzed) and standard wound dressing or a negative pressure 3M Prevena incision management system (Prevena). Only diabetic or obese patients were eligible for the latter comparison. This trial investigated feasability including adherence to protocol of each intervention (goal: > 90% each) and loss to follow-up (goal:To assess the association between the maternal continuum of healthcare and child immunisation in East Africa using propensity score matching (PSM).
Cross-sectional study using Demographic and Health Survey data.
This study was conducted in East African countries.
This study included a weighted sample of 13 488 women with children aged 12–23 months.
Child immunisation was the outcome variable of this study.
The PSM estimates indicate that the average treatment effect on the treated for complete child immunisation was 0.0583, meaning that children of mothers who received a complete maternal continuum of care had a 5.83% higher probability of being fully immunised compared with children of mothers with incomplete care. Expressed relative to the treated group’s mean, this corresponds to a 7.48% increase. Additionally, our results indicated that the population average treatment effect was 0.0629. This means that, on average, a complete continuum of maternal healthcare increases the probability of full child immunisation by approximately 6.29% across the entire population.
The study highlights that children whose mothers receive comprehensive maternal healthcare are more likely to complete their childhood immunisations. This finding underscores the need to integrate immunisation services into maternal healthcare programmes to enhance vaccination coverage and promote better child health. To maximise this connection, improving access to maternal healthcare, especially in underserved regions, is crucial, along with ensuring that immunisation is a regular part of maternal care.
To analyse trends and characteristics of multidrug-resistant (MDR) bacteria over the past 7 years, in relation to patterns of antimicrobial use, to inform rational antimicrobial use and strengthen hospital infection control measures.
Retrospective cohort study.
A large teaching hospital in Tianjin, a major metropolitan city in northern China.
A total of 190 352 inpatients aged >18 years, admitted between 1 January 2017 and 31 December 2023, were included. Patients were eligible if they had complete clinical data and met the five quality control indicators for multidrug-resistant bacteria (QC-MRB), defined in the ‘Hospital Infection Surveillance Specifications’ (WS/T 312–2023). Patients with MDR infections before admission or those with duplicate results from multiple specimens were excluded.
Statistical analysis revealed a detection rate of 12.11% for the five QC-MRB and an incidence rate of 0.20%. The findings also indicated an upward trend in the detection and incidence rates of carbapenem-resistant Enterobacteriaceae, despite a relatively stable rate of antimicrobial use over 7 years. A positive correlation was observed between the incidence of MDR bacteria and the intensity of antimicrobial use within the hospital setting.
The hospital’s bacterial data align with national trends. It established an interdisciplinary management framework for clinical data analysis and prediction of antimicrobial resistance. This approach enhances infection control measures and supports the rational use of antimicrobials.
Adenotonsillectomy is the primary treatment for type 1 obstructive sleep apnoea (OSA1). Although polysomnography (PSG) remains the gold standard for measuring Apnoea-Hypopnoea Index, it is a labour-intensive procedure and does not correlate with improvements in quality of life postadenotonsillectomy. Mouth breathing is associated with poorer quality of life in children. Mandibular movement (MM), which measures mouth opening, is a validated measure of respiratory effort that can be easily and safely assessed in children using the JAWAC technology. This study aims to evaluate the relationship between changes in quality of life and changes in mouth opening in children with OSA1 after undergoing adenotonsillectomy. Secondary objectives include evaluating changes in quality of life, clinical symptoms and other MM and PSG metrics in the same population.
This exploratory, non-randomised, monocentric, prospective cohort study with a non-blinded single arm will include 50 children aged 3–7 years, undergoing adenotonsillectomy at the Clinique Saint Jean, Montpellier, France. Quality of life will be measured using the parent version of the Paediatric Quality of Life Inventory and MM metrics will be measured during PSG using the JAWAC system during the inclusion visit and 3 months after adenotonsillectomy. The primary outcome will be the correlation between the changes in quality of life and mouth opening (1/10 mm) postadenotonsillectomy. Secondary analyses will evaluate changes in clinical symptoms, PSG measures and other MM metrics including respiratory effort, as well as the associations between these measures.
This study was approved by an independent ethics committee (Comité de Protection des Personnes Est) on 24 March 2025 (2024-A02761-46) and will be conducted in accordance with French law, good clinical practice and the guidelines of the Declaration of Helsinki. Study findings will be disseminated through international peer-reviewed journal articles as well as public, academic presentations at national and international conferences.
Chronic subdural haematoma (CSDH) is a common neurosurgical condition in older adults, with a recurrence rate of approximately 7.1–13% after burr-hole drainage. Although surgical adjuncts such as subdural drains and middle meningeal artery embolisation may reduce recurrence, these are not suitable for all patients. Pharmacological strategies, including tranexamic acid, Goreisan and carbazochrome sodium sulfonate hydrate, have shown potential, but high-level evidence remains lacking. A prior retrospective study suggested that a triple oral regimen combining these agents may reduce recurrence. This randomised controlled trial aims to evaluate its efficacy and safety.
This is a prospective, multicentre, open-label, randomised controlled trial conducted across six hospitals in Ibaraki, Japan. A total of 180 patients undergoing first-time burr-hole surgery for CSDH will be randomised 1:1 to receive either triple therapy (Goreisan 7.5 g/day, carbazochrome sodium sulfonate hydrate 90 mg/day and tranexamic acid 750 mg/day for up to 90 days) or standard postoperative care. The primary outcome is recurrence requiring reoperation within 90 days. Secondary outcomes include time to recurrence and haematoma volume reduction on serial CT imaging. All analyses will follow the intention-to-treat principle, using logistic regression, Cox proportional hazards models and mixed-effects models.
Written, informed consent will be obtained from all participants at each participating hospital by trained staff from that hospital. The trial protocol has been approved by the ethics committee of the University of Tsukuba Hospital (approval no. TCRB23-025) and the Institutional Review Boards of all participating centres. Study findings will be disseminated through presentations at scientific conferences and publications in peer-reviewed journals. A summary of the results will also be provided to participating institutions and made publicly available in accordance with the BMJ Open data sharing policy.

ObjectiveTo evaluate the effects of aquatic exercise compared with non-exercise controls and land-based exercise on arterial stiffness and endothelial function.
DesignSystematic review and meta-analyses of randomized controlled trials assessed using the Cochrane risk-of-bias tool and Grading of Recommendations Assessment, Development and Evaluation.
Data sourcesPubMed/MEDLINE, CINAHL Plus, SPORTDiscus, and reference lists, searched from database inception to April 16, 2025.
Eligibility criteriaStudies evaluating chronic aquatic exercise (multi-session interventions) compared with land-based exercise or non-exercise comparison groups in adults, measuring arterial stiffness via pulse wave velocity (PWV) or endothelial function via flow-mediated dilation (FMD).
ResultsThis review includes 18 randomized controlled trials with 845 participants (mean age 65 ± 7 years). Studies compared aquatic exercise with non-exercise controls (8 studies), land-based exercise (6 studies), or both (4 studies). Exercise sessions averaged 50 minutes, 3 times weekly for 11 weeks. Most studies (17 out of 18) implemented moderate-to-vigorous intensity protocols. Aquatic exercise resulted in improvements in arterial stiffness compared with non-exercise controls (7 studies; SMD = –2.37, 95% CI: –4.46 to –0.29; I2 = 98%: low certainty), with most evidence reflecting systemic and peripheral PWV. Changes in arterial stiffness did not differ from those observed after land-based exercise (6 studies; SMD = –0.07, 95% CI: –0.34 to 0.20; I2 = 0%, moderate certainty). For endothelial function, aquatic exercise may improve outcomes versus non-exercise controls (6 studies; SMD = 0.91, 95% CI: 0.39 to 1.43; I2 = 68%; low certainty) and may lead to greater improvements than land-based exercise (7 studies; SMD = 0.55, 95% CI: 0.05 to 1.06; I2 = 75%; low certainty).
ConclusionAquatic exercise improves systemic and peripheral arterial stiffness as well as endothelial function compared with non-exercising controls. Changes in arterial stiffness do not differ from those observed after land-based exercise. Aquatic exercise may provide greater improvement in endothelial function than land-based exercise, though this is supported by low-certainty evidence, and substantial heterogeneity limits confidence in the generalizability of this finding.

To characterise patient and medication-related patterns observed in drug-related pressure ulcers (DRPUs) and provide descriptive findings that may support future consensus-building.
Multicentre retrospective observational study.
20 hospitals across Japan participated in the study with hospital pharmacists specialised in PU care.
A total of 1113 hospitalised patients with existing PUs were included and classified into three groups (definite, probable and no-possibility of DRPUs) based on predefined criteria.
The primary outcome was the description of medication-related characteristics observed in each DRPU classification group, including polypharmacy, initiation of new medications and dose adjustments. Secondary outcomes included differences in ulcer characteristics and functional status across DRPU categories.
The definite group (n=128, 11.5%) showed a significantly higher prevalence of polypharmacy (83.6% vs 71.1% in the no-possibility group, p
Medication-related characteristics such as polypharmacy, initiation of new medications, dose modifications and use of antipsychotics were more frequently observed in the definite DRPU group. These descriptive findings may help characterise the clinical patterns of DRPUs and may inform future hypothesis generation.
To explore the patient and informal-carer reported factors that influence prescribing decisions in the management of borderline personality disorder (BPD).
The study employed a qualitative methodology of semi-structured interviews with patients and informal carers to examine perspectives on prescribing decisions and the factors shaping them.
Interviews were conducted across both primary and secondary care settings in England.
A total of 10 participants were recruited for the study, comprising eight females and two males, all aged 18 years or older. Participants either had a formal diagnosis of BPD or were informal carers of individuals diagnosed with BPD. All participants had experience with the prescribing of medication for the management of BPD.
Thematic analysis, employing both inductive and deductive strategies and informed by agency theory, yielded three interrelated themes: prescribing for symptom relief, the impact of risk on prescribing and difficulties in accessing services. Participants described medication as a necessary means of managing distress, especially when access to psychological therapies was constrained. Despite awareness of potential adverse effects, many expressed a strong desire to make their own decision around medication.
Improving clarity around the likelihood of both symptomatic relief and potential adverse effects through co-designed informational resources may support more informed decision-making in the treatment of BPD. Furthermore, to change prescribing patterns, systemic gaps in the provision of long-term psychological therapies must be addressed.

BackgroundAttention-deficit/hyperactivity Disorder (ADHD) is the most common neurobehavioral condition of childhood and can be controlled with stimulant medication. Evidence-based guidelines endorse use of standardized ADHD symptom reports to facilitate medication titration to therapeutic dosage. Children living in under-resourced areas experience barriers to receiving this recommended evidence-based care. The Remote ADHD Monitoring Program (RAMP) uses a text-based platform to relay symptom reports from caregivers and teachers to healthcare providers. This pilot study is a feasibility study examining intervention uptake. It compares the submission of structured symptom reports in those children enrolled in RAMP compared to usual care as well as utilization of the RAMP platform by providers.
MethodsThis paper describes the protocol to evaluate the feasibility of deploying RAMP in practices serving rural or underserved children. We will recruit 36 dyads from 4 practices in 2 separate states. Each dyad will include a caregiver and their child aged 5–11 years with a diagnosis of ADHD who is starting or reinitiating stimulants. Dyads will be randomized 1:1 to receive the RAMP intervention or usual care with attention controls. Our primary outcome is number of symptom reports (paper assessments in control arm and RAMP reports in intervention arm) per participant that are completed by caregivers and teachers and returned to providers. Our secondary outcome is proportion of submitted RAMP reports that are reviewed by providers.
DiscussionAs telehealth use increases, it is critical that we improve access to high quality care for children with chronic conditions. Leveraging technology may be a meaningful approach to improve efficiency in optimizing medication management. This pilot study tests a text-based platform designed to improve communication between the caregivers and teachers of children with ADHD and health care providers. If successful, a future trial will examine the effectiveness of the RAMP intervention on improvement in symptoms.

Microvascular obstruction (MVO) is a common complication following primary percutaneous coronary intervention (PPCI) for ST-segment elevation myocardial infarction (STEMI) and is strongly associated with adverse clinical outcomes. MVO is a dynamic, multifactorial process shaped by factors spanning the myocardial infarction–reperfusion continuum and by PPCI-related microcirculatory injury, which leaves current early risk stratification—often a static snapshot—with limited power to anticipate its evolution. Renalase, a cardioprotective enzyme, exhibits a post-reperfusion surge that parallels MVO development; periprocedural renalase release may likewise be driven by overlapping mechanisms along the ischaemia–reperfusion pathway. This hypothesis-generating observation supports evaluating the delta-Renalase (periprocedural change in serum renalase) as a candidate association-based biomarker. Accordingly, this study aims to assess whether delta-Renalase is independently associated with MVO in patients with STEMI after PPCI and to evaluate its incremental predictive value, without causal inference.
The Renalase and MicroVascular Obstruction Study (ReMVOS) is a prospective, single-centre, observational cohort study conducted at a nationally accredited chest pain centre in China. We will enrol 266 patients with consecutive STEMI with symptom onset within 12 hours who undergo PPCI. The exposure variable is delta-Renalase, calculated as the increase in serum renalase levels at 24 hours post-PPCI relative to the preprocedural baseline. The primary outcome is the presence of MVO, assessed by cardiovascular magnetic resonance (CMR) performed 2–5 days post-PPCI. Secondary outcomes include infarct size and peak global longitudinal strain quantified by CMR, major adverse cardiovascular events within 90 days and peak oxygen pulse from cardiopulmonary exercise testing (CPET) at the 90-day visit. The independent association and predictive value of delta-Renalase will be evaluated using a prespecified multivariable logistic regression model.
This protocol has been approved by the Ethics Committee of the Third Xiangya Hospital of Central South University (approval No. K24655). All patients will provide written informed consent prior to enrolment. The findings of this study will be disseminated through publications in peer-reviewed international medical journals and presentations at relevant academic conferences.
Myoglobin (Mb) exerts both direct and indirect nephrotoxic effects, contributing to the progression of kidney injury. For patients with rhabdomyolysis (RM) and acute kidney injury (AKI) requiring renal replacement therapy (RRT), Mb clearance is a critical therapeutic goal. Recent studies have indicated that haemoadsorption (HA) combined with continuous renal replacement therapy (CRRT) is an effective strategy for removing circulating Mb. However, clinical data regarding the efficiency of Mb clearance and long-term patient outcomes with this approach remain limited. This study aims to evaluate the efficacy and safety of HA combined with CRRT in treating severe RM and AKI.
This single-center, open-label, randomised controlled trial will be conducted at West China Hospital of Sichuan University. A total of 60 patients with severe RM and AKI will be enrolled and randomly assigned in a 1:1 ratio to either the CRRT group or the CRRT+HA group. Randomisation will be conducted by drawing lots, performed by the patient’s legal representative (with ‘0’ indicating the CRRT group and ‘1’ indicating the CRRT+HA group).
The primary outcome of the study is the plasma clearance of Mb. Secondary outcomes include the plasma clearance of creatine kinase, haemodynamic changes, changes in acute physiology and chronic health II (APACHE) II score and sequential organ failure assessment (SOFA) score, renal function recovery, length of hospital stay, all-cause mortality, and pre- and post-treatment changes in albumin, platelet and haemoglobin counts. Data will be analysed using both intention-to-treat and per-protocol analysis methods.
The study will comply with the Declaration of Helsinki and the Chinese Clinical Trials Act. The study protocol has been approved by the Biomedical Research Ethics Committee of West China Hospital of Sichuan University (2024.1914). Written informed consent will be obtained from all participants. The study results will be presented at academic meetings and in peer-reviewed academic journals.

This study aimed to investigate the evolution of burnout levels and cardiovascular risk among healthcare professionals during the COVID-19 pandemic, identifying associated risk factors, with a particular focus on the impact of working hours, job roles and working units.
A longitudinal, observational study was conducted.
The study was carried out in a medical centre in central Taiwan, encompassing various healthcare settings.
A total of 1502 healthcare workers participated, including nurses, medical technicians, resident doctors, attending physicians and administrative staff. Participants were selected based on consistent completion of a 4-year questionnaire, with exclusion criteria for those who did not complete.
The primary outcome measured was burnout levels using the Chinese version of the Copenhagen Burnout Inventory. The secondary outcome was cardiovascular risk calculated from employees’ health check-up data using the Framingham Risk Score.
Cardiovascular risk showed an upward trend over 4 years. Personal and work-related burnout significantly decreased from 2019 to 2020 but increased from 2020 to 2022, aligning with changes in weekly working hours. Nurses exhibited the most pronounced fluctuations, likely due to their younger average age, shorter professional tenure and frequent direct patient contact, which may heighten vulnerability to pandemic-related stressors. In contrast, attending physicians demonstrated age as a protective factor against burnout, as greater seniority, clinical experience and professional maturity may buffer stress and foster resilience. Participants who worked in COVID-related units generally had elevated burnout levels and working hours. During the initial outbreak in 2020, employees working in COVID-related units had reduced working hours but stable burnout levels, while employees in non-COVID-related units experienced decreased burnout.
This study highlights the critical impact of long working hours on burnout among healthcare professionals during the COVID-19 pandemic. Nurses emerged as a vulnerable group, sensitive to pandemic-induced changes, while attending physicians exhibited more resilience. COVID-related units face greater stress and are less likely to benefit from reductions in patient numbers and working hours during the pandemic. Our findings underscore the urgent need for tailored interventions, such as regulated work hours, flexible scheduling and enhanced organisational and peer support, to protect healthcare workers’ well-being. These strategies can strengthen workforce resilience and sustainability in future public health crises.
Genitourinary syndrome of menopause (GSM) is a prevalent condition among breast cancer survivors, often exacerbated by oncological treatments. Hormonal therapies are typically contraindicated in this population, necessitating effective non-hormonal interventions.
This randomised controlled trial aims to compare the effectiveness and cost-effectiveness of multimodal pelvic floor physiotherapy—comprising pelvic floor muscle training, non-ablative radiofrequency, therapeutic pelvic health education and the use of vaginal moisturisers—versus fractional CO2 laser therapy combined with vaginal moisturisers in alleviating GSM symptoms in breast cancer survivors. Participants will be randomly assigned to one of the two intervention groups. Primary outcomes include measures of sexual function (assessed by the Female Sexual Function Index), subjective pelvic perineal pain intensity (measured with a 100 mm Visual Analogue Scale) and health-related quality of life (assessed by the Functional Assessment of Cancer Therapy-Breast), assessed at baseline, post-intervention and at 3, 6 and 12 months of follow-up. Statistical analyses will be conducted to evaluate the clinical efficacy and cost-effectiveness of the interventions.
The study protocol has been approved by the Ethics and Health Research Committee of the University of Alcalá (Reference: CEIP/2024/1/012). All participants will provide informed consent prior to inclusion in the study. Findings will be disseminated through peer-reviewed journals and conference presentations, and by engaging with patient associations and survivor groups through tailored materials.
The MD Anderson Oropharynx Cancer (MDA-OPC) cohort is a unique single-institution, prospective longitudinal cancer cohort. The cohort aims to enhance the therapeutic index of OPC management by supporting data needs for independent investigators to conduct rigorous observational studies examining exposures and factors associated with acute and late toxicities, cancer progression, recurrence, new malignancies and quality of life in OPC survivors.
A total of 1811 patients with OPC with a minimum follow-up of 6 months have been consented to our prospective registry between 18 March 2015 and 29 December 2023. Clinical and treatment (Tx) data are available on all patients, including previously untreated patients (1443, 80%). Most previously untreated patients (97%) consented to longitudinal patient-reported outcomes and functional assessments for critical time points including pre-Tx, during-Tx and post-Tx at 3–6 months, 12 months, 18–24 months and annually up to 5 years.
The median age for the MDA-OPC cohort is 66 years (range, 25–96) with the majority being male (89%), white (92%) and with human papillomavirus (HPV)/p16-associated OPC (88%) primarily located in the tongue base or tonsil (90%). For previously untreated patients, 79% were diagnosed with stage I/II disease, and nearly half underwent curative intent chemoradiation. Overall survival was significantly higher for HPV/p16-associated OPC at 1 year (98% vs 93%) and 5 years (83% vs 54%; p
Future work includes expansion of the MDA-OPC cohort and survivorship surveillance to 10 years under the recently funded OPC-SURVIVOR research programme (P01CA285249), which aims to identify non-invasive, clinic-ready biomarkers and examine novel phenotypes and mechanistically matched mitigation strategies for latent OPC sequelae. Additionally, we aim to expand our advanced data infrastructure by integrating large data streams from parallel clinical trials and imaging registries.

IntroductionReports indicate increasing prevalence rates of successive natural disasters, and the negative impact on existing infrastructures are well documented. However, factors impacting outcomes on both communities and individuals remain unclear. For historically underserved communities, the effects of disasters are exacerbated by pre-existing barriers that make efforts to recovery difficult. Thus, understanding the nuance of their circumstances and experience is crucial to helping build resilience in these communities and inform preparedness and response efforts.
ObjectiveThrough this study, we sought to qualitatively understand the lived experience of historically underserved communities in the context of natural disasters to support the development and/or adoption of resources.
MethodsPhotovoice was used to guide semi-structured interviews with participants recruited from three communities (Kashmere Gardens, Greater Third Ward, Greater Fifth Ward) in Houston, TX. Reflexive thematic analysis was employed to generate themes accurately depicting participant experiences. Reflexivity, persistent observation, and triangulation were employed to increase trustworthiness in analysis.
ResultsFive key themes emerged from analysis: 1) Acute and long-term damage from natural disasters requires sustained recovery efforts; 2) Gaps and opportunities exist in city, state, and federal support mechanisms; 3) Strengthening and expanding support networks and community resources after extreme weather events is critical; 4) Need to address structural barriers to disaster preparedness and coping; and 5) Recognizing and mitigating the broad mental health impacts of natural disasters.
ConclusionThe lived experiences of individuals from historically underserved communities in Houston highlight a complex interaction of psychosocial, structural, and cultural factors that influence both community resilience and vulnerability. Understanding this interplay is crucial to informing policy efforts that prioritize resilience building in these communities. Implications from these findings are discussed.

ObjectiveRadiation-induced brain injury (RIBI) is a significant complication following radiotherapy for brain tumors, leading to neurocognitive deficits and other neurological impairments. This study aims to identify potential biomarkers and therapeutic targets for RIBI by utilizing advanced proteomic techniques to explore the molecular mechanisms underlying RIBI.
MethodsA rat model of RIBI was established and subjected to whole-brain irradiation (30 Gy). Tandem mass tagging (TMT)-based quantitative proteomics, combined with high-resolution mass spectrometry, was used to identify differentially expressed proteins (DEPs) in the brain tissues of irradiated rats. Gene Ontology (GO) enrichment and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses were conducted to identify the biological processes and pathways involved. Protein-protein interaction (PPI) networks were constructed to identify key hub proteins.
ResultsA total of 35 DEPs were identified, including PHLDA3, APOE and CPE. GO enrichment analysis revealed that the DEPs were mainly involved in lipid transport, cell adhesion, and metabolic processes. KEGG analysis highlighted the enrichment of pathways related to metabolism, tight junctions, and PPAR signaling. APOE was identified as a key hub protein through PPI network analysis, indicating its potential role in RIBI pathophysiology. Immunohistochemistry further validated the increased expression of PHLDA3, APOE, and CPE in the brain tissue of irradiated rats.
ConclusionThis study provides valuable insights into the molecular mechanisms of RIBI by identifying key proteins and their associated pathways. The findings suggest that these proteins, particularly APOE and PHLDA3, could serve as potential biomarkers and therapeutic targets for clinical intervention in RIBI. These results not only enhance our understanding of RIBI’s molecular pathology but also open new avenues for the development of targeted therapies to mitigate radiation-induced neurotoxicity.
Internalised racism (IR) is broadly defined as the acceptance of negative racial stereotypes, beliefs and attitudes about one’s own racial or ethnic group. IR is increasingly recognised as a critical component and consequence of racial stress and trauma. Although IR has been linked to a variety of adverse mental and physical health outcomes, the phenomenon remains under-represented in intervention research. This scoping review addresses this gap by systematically mapping the range of interventions and intervention components that explicitly target IR among racially or ethnically minoritised communities and their health-related outcomes. This protocol paper will describe the process of the scoping review.
This review will follow methodology from the Joanna Briggs Institute and report using the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) checklist. Using identified controlled vocabulary and keywords, searches will be undertaken using the following databases: MEDLINE, PsycInfo, Embase and Web of Science. This review will include studies describing any intervention or intervention component designed to reduce IR that is conducted with racially or ethnically minoritised populations in any context or setting. No date limit will be applied, and the study must be available in English. Conceptual or opinion pieces without a clear intervention framework will be excluded. Two reviewers will independently screen and select sources and extract data on intervention characteristics, theoretical underpinnings, outcomes and implementation details. Descriptive statistics will summarise study characteristics and outcomes, while a narrative synthesis will explore how interventions conceptualise and address IR. The findings will map existing approaches, highlight research gaps and inform future clinical practice and intervention development.
As this review uses published and publicly available data, no ethical approval is required. The findings will be disseminated through a peer-reviewed publication, conference presentations and briefs to stakeholder networks.
This protocol is registered on the Open Science Framework (https://doi.org/10.17605/OSF.IO/4VDBX).

Background/ObjectivesObesity is a chronic metabolic disorder, and its prevalence in Bangladesh is increasing at an alarming rate. Previous reports have suggested a significant association between Vitamin D receptor (VDR) gene polymorphisms and obesity, but with inconsistent results. The purpose of our study was to investigate the association between two single-nucleotide polymorphisms (SNPs) (Apal, rs7975232, and Taql, rs731236) of the VDR gene and the risk of obesity in the Bangladeshi population. Moreover, we looked at serum VDR levels and serum 25-hydroxy vitamin D levels in people with obesity (n = 124) and healthy controls (n = 126).
MethodsGenotyping was performed using Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP). General linear model and multivariate logistic regression analysis were used to calculate the adjusted odds ratio (OR) along with 95% confidence intervals (CI) and P-values.
ResultsSerum VDR level was downregulated in people with obesity compared to healthy controls (P A) polymorphism, the CA Heterozygous genotype carried a 1.93-fold higher risk of developing obesity (OR=1.93, 95% CI = 1.10–3.41, P = 0.023). On the contrary, for TaqI, rs731236 (T > C), no significant association was found for both heterozygous and mutant homozygous genotypes.
ConclusionWe report the downregulation of serum VDR levels and serum 25-hydroxy vitamin D levels in people with obesity. Moreover, a polymorphism of Apal (rs7975232 C > A) in the VDR gene increases the risk of developing obesity in the Bangladeshi population.
