Commentary on: Heslop, P., Lauer, E. (2024). Strategies to prevent or reduce inequalities in specific avoidable causes of death for adults with intellectual disability: A systematic review. British Journal of Learning Disabilities, 52(2), pp.312-349.
Implications for practice and research Preventative interventions and reasonable adjustments are required to address health inequalities experienced by adults with intellectual disability. Future research should focus on policy, population and individual interventions that reduce health inequalities and avoidable deaths.
There is well-established research evidence regarding the substantial health inequalities experienced by many adults with intellectual disabilities, with significant implications for their health, well-being and quality of life. Despite this evidence, many continue to die prematurely from conditions amenable to early interventions and preventative strategies. Limited knowledge, skills and confidence regarding the needs of adults with intellectual disabilities by some health professionals is evident. Reasonable adjustments can contribute positively...
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:by Qian Yue Tan, Kinda Ibrahim, Helen C.

BackgroundPeople with Parkinson’s (PwP) and their caregivers have to manage multiple daily healthcare tasks (treatment burden). This can be challenging and may lead to poor health outcomes.
ObjectiveTo assess the extent of treatment burden in Parkinson’s disease(PD), identify key modifiable factors, and develop recommendations to improve treatment burden.
MethodsA mixed-methods study was conducted consisting of: 1) a UK-wide cross-sectional survey for PwP and caregivers using the Multimorbidity Treatment Burden Questionnaire (MTBQ) to measure treatment burden levels and associated factors and 2) focus groups with key stakeholders to discuss survey findings and develop recommendations.
Results160 PwP (mean age = 68 years) and 30 caregivers (mean age = 69 years) completed the surveys. High treatment burden was reported by 21% (N = 34) of PwP and 50% (N = 15) of caregivers using the MTBQ. Amongst PwP, higher treatment burden was significantly associated with advancing PD severity, frailty, a higher number of non-motor symptoms, and more frequent medication timings (>3 times/day). Caregivers reporting higher treatment burden were more likely to care for someone with memory issues, had lower mental well-being scores and higher caregiver burden. Three online focus groups involved 11 participants (3 PwP, 1 caregiver and 7 healthcare professionals) recruited from the South of England. Recommendations to reduce treatment burden that were discussed in the focus groups include improving communication. clear expectation setting, and better signposting from healthcare professionals, increasing education and awareness of PD complexity, flexibility of appointment structures, increasing access to healthcare professionals, and embracing the supportive role of technology.
ConclusionsTreatment burden is common amongst PwP and caregivers and could be identified in clinical practice using the MTBQ. There is a need for change at individual provider and system levels to recognise and minimise treatment burden to improve health outcomes in PD.

Determining the quality of medicines remains a challenge, particularly in low- and middle-income countries, where regulatory oversight and enforcement vary, and resources and infrastructure for quality testing are often constrained. In these settings, price is often used as a proxy for higher-quality medicines, yet empirical evidence supporting this assumption remains scarce. We conducted a mystery shopper survey in over 1,200 retail pharmacies across urban and rural areas in the six geopolitical zones of Nigeria, purchasing one drug sample from a list of twenty branded medicines, including analgesics, antimalarials, antibiotics, antihypertensives, and multivitamins. A sub-sample of the purchased medicines (N = 246) was tested for quality, defined as passing a laboratory test using High-Performance Liquid Chromatography (HPLC) to measure the Active Pharmaceutical Ingredient (API) content of each medicine. Using probit regressions, we examined the extent to which price is associated with quality, controlling for observable pharmacy and drug sample characteristics. A 1% increase in price is associated with a 16.7 percentage point increase in the probability of passing the laboratory test, conditional on other factors. Receiver Operating Characteristic (ROC) analysis shows strong out-of-sample classification performance, with an Area Under the Curve (AUC) of 0.82 for the price-only model, indicating that price alone explains much of the variation in quality. Other results show that medicines organized by brand and displaying visible expiration dates may signal higher quality, while the presence of other observable characteristics (e.g., packaging, storage, display) shows more counterintuitive associations with drug quality in this context. Stratified analyses show that the association between price and quality is particularly strong for analgesics and antibiotics. These findings suggest that price appears to be a reliable signal of medicine quality, whereas other characteristics of pharmacies and drug samples provide weaker and less consistent indicators. This underscores the need for stronger regulatory oversight, greater market transparency, and targeted consumer education to promote safer access to quality medicines.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.
The ‘time-limited trial’ for patients with critical illness is a collaborative plan made by clinicians, patients and families to use life-sustaining therapies for a defined duration. After this period, the patient’s response to therapy informs decisions about continuing recovery-focused care or transitioning to comfort-focused care. The promise of time-limited trials to help navigate the uncertain limits and benefits of life-sustaining therapies has been extensively discussed in the palliative and critical care literature, leading to their dissemination into clinical practice. However, we have little evidence to guide clinicians in how to conduct time-limited trials, leading to substantial variation in how and why they are currently used. The overall purpose of this study is to characterise the features of an optimal time-limited trial through a rich understanding of how they are currently shaping critical care delivery.
We are conducting an observational, multicentre, focused ethnography of time-limited trials in patients with acute respiratory failure receiving invasive mechanical ventilation in six intensive care units (ICUs) within five hospitals across the US. Study participants include patients, their surrogate decision makers and ICU clinicians. We are pursuing two complementary analyses of this rich data set using the open-ended, inductive approach of constructivist grounded theory and, in parallel, the structured, deductive methods of systems engineering. This cross-disciplinary, tailored approach intentionally preserves the tension between time-limited trials’ conceptual formulation and their heterogeneous, real-world use.
This study has been reviewed and approved by the University of Wisconsin Institutional Review Board (IRB) as the single IRB (ID: 2022-1681; initial approval date 23 January 2023). Our findings will be disseminated through peer-reviewed publication, conference presentations, and summaries for the public.
Transoral robotic surgery (TORS) is a minimally invasive technique for surgical removal of tumours of the tonsil and lateral oropharynx. Surgical defects after TORS lateral oropharyngectomy are traditionally left open to heal by secondary intention, resulting in significant postoperative pain and secondarily resulting in delayed swallowing and discharge. Although multimodal analgesia can improve postoperative pain control, no studies to date have assessed the impact of adjunct surgical interventions for reducing postoperative pain after TORS. Buccal fat rotation flap is a regional reconstruction option after TORS lateral oropharyngectomy and provides immediate coverage of the open surgical wound. However, the impact of buccal fat rotation flap reconstruction on postoperative pain and swallowing remains unclear. This trial aims to compare postoperative pain outcomes in patients who undergo TORS lateral oropharyngectomy with and without buccal fat rotation reconstruction.
This protocol outlines a single centre, parallel, unblinded, phase II, randomised control trial. Inclusion criteria include adult patient (≥18 years) undergoing TORS lateral oropharyngectomy for early to intermediate stage tonsillar squamous cell carcinoma (T1-2N0-1 p16+/–) or early to intermediate stage salivary gland tumours of the palatine tonsils. Exclusion criteria include a history of prior head and neck squamous cell carcinoma, prior head and neck radiotherapy, retropharyngeal lymphadenopathy, bilateral lymphadenopathy, need for bilateral neck dissection, baseline trismus, opioid use or drug addiction, need for open surgery (transcervical lateral oropharyngectomy), free tissue transfer, or alternative regional flap, and pregnancy. All patients are planned for a TORS lateral oropharyngectomy. The intervention group will have a buccal fat rotation flap reconstruction, and the control group will be allowed to heal via secondary intention. The allocation sequence will be created using a computer-generated random sequence with a permuted block strategy. The allocation sequence will be concealed until the time of assignment. The primary outcome is postoperative pain intensity during rest and swallowing using the visualised analogue scale. Secondary outcomes include postoperative complications, other adverse events, patient-reported speech and swallowing, opioid usage, length of hospital stay, feeding tube dependence and blood glucose levels. The trial has a target sample size of 40 patients. Statistical analysis of the primary outcome will be analysed in an intention to treat analysis using a linear mixed effects model.
The study was approved by the University Health Network Coordinated Approval Process for Clinical Research. Study number CAPCR ID: 24-5894. All participants will be required to provide written informed consent to participate. Findings will be presented at national conferences and published in medical journals.
Many patients receive oral anticoagulation for reduced stroke risk in atrial fibrillation or as treatment or prevention of venous thromboembolism. Oral factor Xa inhibitors (oral FXaI, eg, apixaban, edoxaban or rivaroxaban) are commonly prescribed for this indication. Dabigatran, an oral direct thrombin inhibitor, is similarly approved. In vitro and animal model evidence suggests that dabigatran also has direct effects on Staphylococcus aureus virulence and infection. Observational data have shown that dabigatran users are less likely to develop S. aureus bacteremia (SAB), and a small randomised controlled trial showed that dabigatran has anti-S. aureus effects when compared with low molecular weight heparins during bloodstream infection. We seek to answer whether dabigatran is superior to the oral FXaIs in achieving better SAB outcomes among patients who independently require oral anticoagulation. We report the intervention-specific protocol, embedded in an adaptive platform trial.
The S. aureus Network Adaptive Platform (SNAP) trial [NCT05137119] is a pragmatic, randomised, multicentre adaptive platform trial that compares different SAB therapies for 90-day mortality rates. For this intervention (‘Dabi-SNAP’), patients receiving therapy with an oral FXaI will be randomised to continue as usual or to change to dabigatran as of the next scheduled dose. All subjects will receive standard of care antibiotics and/or antibiotics allocated through other active domains in the platform. As the choice of anticoagulant may not demonstrate large differences in mortality, a ranked composite of death and adverse outcomes (Desirability of Outcome Ranking, or DOOR) was chosen as the primary outcome.
The study is conditionally approved by the research ethics board of the McGill University Health Centre: identifier 2025-10900. Trial results will be published open access in a peer-reviewed journal and presented at a global infectious disease conference. The trial is registered at clinicaltrials.gov with the identifier NCT06650501.
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.

To assess how preoperative anaemia affects surgical outcomes in elderly patients within a resource-limited setting.
Prospective cohort study.
Two comprehensive specialised hospitals in Ethiopia.
Participants consisted of 224 patients aged 65 years and older who underwent surgery between 1 December 2024 and 29 March 2025.
Perioperative blood transfusions were the primary outcome. Secondary outcomes included intensive care unit (ICU) admission, risk of postoperative complications, prolonged hospitalisation, poor recovery quality and in-hospital mortality.
The anaemic group required transfusions of three or more units more frequently than the non-anaemic group (10.5% vs 2.6%; absolute risk difference 8.0%). Their perioperative transfusion rates were significantly higher (42.3% vs 18.4%; p
Preoperative anaemia significantly increases the risk of transfusion, poor recovery, ICU admission, prolonged hospitalisation and in-hospital mortality in older patients who underwent surgery. In resource-limited settings, improving perioperative outcomes should prioritise the early detection and treatment of anaemia.
The Communication and Symbolic Behaviour Scales Developmental Profile Infant–Toddler Checklist (CSBS DP ITC) is a screening tool designed to identify early deficits in social communication, expressive speech/language and symbolic functioning in children aged 6–24 months. This study aimed to translate and content validate the CSBS DP ITC into Modern Standard Arabic.
Methodological study involving translation and content validation.
The study was conducted in the United Arab Emirates.
The translation process involved five bilingual translators and one monolingual Arabic language expert. Ten experts participated in the content validation phase, and 10 parents of young children participated in the face validity assessment.
Content Validity Indices (CVIs), including the Item-level CVI (I-CVI), the Scale-level CVI by Average (S-CVI/Ave) and the S-CVI by Universal Agreement (S-CVI/UA), along with modified kappa statistics, were calculated to assess item-level and scale-level clarity, relevance and comprehensiveness.
Expert panel ratings showed high clarity (I-CVI: 0.8–1, S-CVI/Ave: 0.98, S-CVI/UA: 0.88) and similar relevance scores. Face validity assessments yielded clarity I-CVI scores of 0.9–1, with S-CVI/Ave at 0.98 and S-CVI/UA at 0.8. The modified kappa statistic ranged from 0.89 to 1, indicating strong agreement among parents.
The CSBS DP ITC was effectively translated and content validated into Modern Standard Arabic. The calculated CVI values ranged from excellent to acceptable. This step establishes a foundation before proceeding to full psychometric testing of the instrument, paving the way for a reliable and culturally appropriate tool to identify early communication delays for use across the Arab-speaking population.

The objective of this study was to examine whether different types of mental-imagery training focused on the vocal apparatus can enhance awareness of the vocal tract and diaphragm (vocal awareness) in non-professional singers.Sixty participants with no singing education received one of three training conditions: following instructions based on 1) a description of the physiological changes that take place during phonation (physiological description), 2) imitating an action using the vocal apparatus (imitative action), and 3) a metaphorical narration. Imitative action and metaphorical narration were conceptualized as more imaginative forms of training. Vocal awareness was assessed with a questionnaire that participants completed before and after the training. The questionnaire measured three indices: vocal apparatus representation, vocal apparatus interoceptive awareness, and vocal self-regulation. Results showed that all three types of training program significantly enhanced vocal awareness, but imitative action and metaphorical narration were more effective for interoceptive awareness, and metaphorical narration was more effective for self-regulation. In conclusion, the two imaginative forms of training were more effective than physiological description for improving vocal awareness.by Omar Fitian Rashid, Saba A. Tuama, Humam Al-Shahwani
In modern digital communication, Confidentiality of text transmission is remains a concern in the current online communication as cyber threats and intrusion. To address these challenges, this paper proposes a dual-layered security system that integrates cryptography and multi-image steganography to strengthen text protection during transmission. The cryptography layer is done based eight steps; in the first one, the message is converted to ASCII format, then convert the ASCII values into their equivalent binary numbers and make a complement to the binary values where each 0’s becomes 1’s and vice versa. In the next step, it needs to enter a key that includes a combination of characters, numbers, and special characters. This key is also converted to binary, and then the XOR operation is made between the message of the binary values and the key. In the fifth step, switching the values of each two adjacent binary values are together and converted to decimal values. While the second layer embeds the ciphertext in several cover images using a randomized codebook along with the Least Significant Bit (LSB) substitution, thus enhancing undetectability. Experimental evaluation demonstrates fast execution times for both the encryption/decryption processes and the multi-image hiding/extraction procedures. The achieved results validate that the proposed system provides an efficient and highly secure framework for protecting sensitive information.by Allison Anbari, Zachary Massey, Abigail Adediran, Na Wang, LaRissa Lawrie, Priscilla Martinez, Denis McCarthy
Alcohol consumption increases breast cancer risk. We evaluated the responses of 748 United States female participants ages 21–29 to health warning messages addressing the relationship between alcohol consumption and increased breast cancer risk. In an online experiment, participants were randomly assigned to view standalone health warning messages about alcohol, breast cancer, and breast cancer health effects with varying picture and text attributes. Participants then completed post-message exposure assessments that included an immediate open-ended response to the message prompt. We conducted a qualitative content analysis of the responses and coded deductively based on constructs from the Message Impact Framework including message reactions, attitudes and beliefs, and behavioral intentions. These constructs and corresponding variables were present in participants’ responses. Response type did not vary by participants’ demographics or the attributes of the health warning message they viewed. The code new information was applied to 20% of the responses, indicating that those participants had no prior knowledge of alcohol and breast cancer risk. Alcohol and breast cancer messaging could impact drinking behaviors. Given the frequency of responses indicating a lack of awareness, more work in cancer prevention and population health messaging is warranted.by Nailya Ibragimova, Arailym Aitynova, Seitzhan Turganbay, Marina Lyu, Alexandr Ilin, Tamari Gapurkhaeva, Galina Ponomareva, Karina Vassilyeva, Diana Issayeva, Amirkan Azembayev, Serzhan Mombekov, Aralbek Rsaliyev, Nurgul Sikhayeva, Yergali Abduraimov, Saki Raheem
Iodine-based antiseptics are essential in wound care but are often limited by cytotoxicity, instability, and rapid iodine release. Novostron is a novel polymer–iodine complex incorporating dextrin, polyvinyl alcohol, and metal ions, designed to enable controlled iodine release. Structural integrity and composition were confirmed by ¹H and 13C NMR spectroscopy and physicochemical analysis, indicating a molecular weight of ~9500 g/mol, a pH of 4.23, and an iodine content of 8.13%. Pharmacokinetic analysis in rabbits demonstrated that following a single dermal application, systemic iodine absorption was minimal, with peak blood iodine concentrations remaining within physiological limits and rapid elimination within 24 hours. Evaluation of thyroid function revealed no significant changes in serum T₃, T₄, or TSH levels compared with those of the controls, confirming that topical application of Novostron does not disrupt thyroid homeostasis. In compliance with OECD guidelines in rabbits, guinea pigs, and rats, Novostron showed no signs of dermal irritation, skin sensitization, or systemic toxicity (LD₅₀ > 2000 mg/kg). In a rat cotton pellet granuloma model, Novostron significantly reduced the inflammatory mass (23.65% inhibition), supporting its anti-inflammatory potential. In a murine burn model, Novostron accelerated wound contraction (25.95% at day 10), increased epidermal thickness, and enhanced collagen deposition (~44%), outperforming controls and matching or exceeding betadine. These findings suggest that Novostron promotes tissue repair by modulating inflammation. Overall, Novostron demonstrated a favourable preclinical safety and efficacy profile, and its polymer–iodine composition, which enables controlled release and localized activity highlights its potential as a promising topical therapeutic. However, the study was limited to animal models and short-term observation; further long-term and clinical investigations are needed to confirm its translational potential in human wound healing.There is limited research exploring the age-related difference in communication when describing pain experiences. This project aimed to identify key differences between adolescents’, young adults’ and adults’ (i) preferred communication method, (ii) language content and (iii) lexical amount and variety when discussing their persistent pain experience using chatbot technology.
An exploratory concurrent nested mixed-methods design using a comparative analysis.
Participants were recruited through a convenience sampling strategy from two tertiary multidisciplinary pain centres in Australia.
20 adolescents, 20 young adults and 20 adults completed a pain history assessment using the Dolores application. The inclusion criteria for this study were (i) persistent non-cancer pain for at least 3 months, (ii) 10 years of age and over and (iii) adequate expressive and receptive language skills to complete the required tasks in English, as determined by clinicians in the treating team.
Drawn, voice and typed responses provided by participants during the chatbot interaction were analysed using content analysis. Fisher’s exact tests and 2 tests were used to examine differences between age groups. Strong effect size estimates generated from comparative analyses suggested that adolescents were the most likely age group to utilise drawing (p=0.153, Cramer’s V=0.268), preferred typing over speaking (p==0.007, Cramer’s V=0.433). Young adults used the greatest number and variety of words in response to chatbot questions including evaluative language (p=0.097, Cramer’s V=0.296). Adults tended to use more metaphors (p=0.085, Cramer’s V=0.305) and had a strong preference for speaking over typing (p=
The results of this study provide insights into age-related differences in communication and preferences when using technology to communicate about persistent pain. Future research exploring individualised age-related approaches to pain assessment, supported by the findings of this study, in comparison to current standardised assessments administered by clinicians are warranted.
Delays in cancer diagnosis for patients with non-specific symptoms (NSSs) lead to poorer outcomes. Rapid Diagnostic Clinics (RDCs) expedite care, but most NSS patients do not have cancer, highlighting the need for better risk stratification. This study aimed to develop biomarker-based clinical prediction scores to differentiate high-risk and low-risk NSS patients, enabling more targeted diagnostics.
Retrospective and prospective cohort study.
Secondary care RDC in London.
Adult patients attending an RDC between December 2016 and September 2023 were included. External validation used data from another RDC.
The primary outcome was a cancer diagnosis. Biomarker-based risk scores were developed using Latent Class Analysis (LCA) and Least Absolute Shrinkage and Selection Operator (LASSO). Model performance was assessed using logistic regression, receiver operating characteristic curves (AUROC) and decision curve analysis.
Among 5821 RDC patients, LCA identified high white cell count, low haemoglobin, low albumin, high serum lambda light chain, high neutrophil-to-lymphocyte ratio, high serum kappa light chain (SKLC), high erythrocyte sedimentation rate (ESR), high C-reactive protein (CRP) and high neutrophils as cancer risk markers. LASSO selected high platelets, ESR, CRP, SKLC, alkaline phosphatase and lactate dehydrogenase. Each one-point increase in score predicted higher odds of cancer (LCA: AOR 1.19, 95% CI 1.16 to 1.23; LASSO: AOR 1.29, 95% CI 1.25 to 1.34). Scores ≥2 predicted significantly higher cancer odds (LCA: AOR 3.79, 95% CI 2.91 to 4.95; LASSO: AOR 3.44, 95% CI 2.66 to 4.44). Discrimination was good (AUROC: LCA 0.74; LASSO 0.73). External validation in 573 patients confirmed predicted increases in cancer risk per one-point LASSO score rise (AOR 1.28, 95% CI 1.15 to 1.42), with a borderline increase for LCA (AOR 1.16, 95% CI 1.06 to 1.27).
Biomarker-based scores effectively identified NSS patients at higher cancer risk. LCA captured a broader biomarker range, offering higher sensitivity, while LASSO achieved higher specificity with fewer markers. These scores may also help detect severe benign conditions, improving RDC triage. Further validation is needed before broader clinical implementation.
Large differences exist in chronic kidney disease (CKD) rates between countries, but differences within diverse populations living in the same setting with universal healthcare are not well understood.
To compare dialysis prevalence, CKD risk factors and control, and CKD progression by ethnicity and birth country in an ethnoculturally diverse setting with high rates of kidney disease and universal healthcare.
Scarborough, Toronto’s most diverse region and site of Canada’s largest regional dialysis programme.
Double observational cohort study of 2397 participants: a retrospective cohort of 1116 residents who received dialysis between 2016–2019, and a prospective cohort of 1281 individuals with non-dialysis CKD followed for 3 years between 2010–2015 in Scarborough.
Dialysis prevalence, calculated by comparing frequencies of birth countries and ethnicities in the dialysis cohort with census-derived community frequencies. Secondary outcome measurements were traditional CKD risk factor prevalence (diabetes, hypertension, cardiovascular disease) and control (haemoglobin A1c, blood pressure); and CKD progression (estimated glomerular filtration rate decline, proteinuria) adjusted for socioeconomic status in the non-dialysis cohort.
Dialysis prevalence was 4.2 times higher in immigrants (p
Despite universal healthcare access, marked disparities in CKD risks and rates exist within ethnoculturally diverse immigrants living in this Canadian kidney disease hotspot. More focused research and tailored interventions are required.
