This study aimed to systematically delineate the clinical characteristics and identify the key risk factors associated with methicillin-resistant Staphylococcus aureus (MRSA) infections in burn patients, thereby informing targeted preventive measures and therapeutic strategies. This retrospective study included 270 burn patients with Staphylococcus aureus (S. aureus) infections at a Chinese centre (2019–2022), comprising 127 MRSA and 143 methicillin-susceptible S. aureus (MSSA) cases. Clinical data were analysed to assess infection profiles, resistance patterns and MRSA risk factors. Amongst the infections, 68.1% (184/270) were caused by multi-drug resistant S. aureus, specifically 47.0% (127/270) by MRSA and 21.1% (57/270) by MSSA. The predominant resistance pattern (penicillin, oxacillin, gentamicin, clindamycin, erythromycin, ciprofloxacin, levofloxacin, tetracycline) accounted for 23.9% (44/184) of multidrug-resistant cases. The overall MRSA detection rate was 47.0% (127/270). Univariate analysis identified multiple factors significantly associated with MRSA infection (p < 0.05). Multivariate analysis identified the use of ≥ 3 types of antibiotics as an independent risk factor for MRSA infection in burn wounds. The detection rate of multi-drug resistant S. aureus (including MRSA) infections in burn wounds is relatively high. A number of variables are the influencing factors for MRSA infections. Medical personnel should adopt infection control measures to block the transmission of multi-drug resistant bacteria (including MRSA).
Parenting stress among clinical nurses has been associated with turnover-related outcomes. For many nurses, critical periods of career development and accumulated clinical responsibility overlap with reproductive and early parenting years. Features of nursing work may shape parenting stress through demands related to scheduling, workload, and limited flexibility.
Integrative literature review.
An integrative literature review was conducted following the methodological framework of Whittemore and Knafl. The final searches across three databases (CINAHL Complete, Medline, and Embase) were completed on May 14, 2026. Eligible articles were published in English, addressed parenting stress, and, when empirical, included nurses as a distinct population. Reporting followed PRISMA guidelines.
Eight articles met all inclusion criteria. Countries of origin included South Korea, Turkey, and China. Approximately 1667 nurse-parent participants were represented across the included studies. Main themes included as follows: (1) Work-Family Role Conflict and Parenting Stress, (2) Parenting Stress Across Career and Family Life Stages, (3) Parenting Stress and Nurse Workforce Outcomes, and (4) Organizational and Structural Contributors to Parenting Stress.
Parenting stress appears to be a relevant nursing workforce issue shaped by structural conditions of practice. The structure and demands of patient care may intensify parenting stress. Additional research is needed to examine the effects of parenting stress in clinical nurses and the implications for nurse retention.
Organizational and policy-level interventions (including family-friendly scheduling, accessible childcare, and structured peer support programs) may support workforce sustainability among nurse-parents.

ObjectiveThis study aimed to comprehensively analyze differentially expressed genes (DEGs) in chondrocytes from patients with knee osteoarthritis (OA) by integrating multiple machine learning algorithms and bioinformatics techniques, to unravel the underlying molecular mechanisms associated with OA chondrocytes, and to provide novel insights for the innovation of clinical therapeutic strategies.
MethodsWe downloaded the GSE117999, GSE114007, GSE169077, GSE246425, and GSE178557 datasets from the public Gene Expression Omnibus (GEO) database as the training set, while GSE57218 served as an independent validation set. To ensure data consistency and comparability, the training set was normalized, and the ComBat algorithm was applied to eliminate batch effects, yielding a merged gene expression dataset. Subsequent differential expression analysis was performed to identify genes with significant changes under disease conditions, followed by enrichment analysis. To more accurately identify genes closely linked to disease characteristics, we independently analyzed the merged dataset using three machine learning algorithms: Lasso regression, random forest, and support vector machine (SVM). The intersection of results from these three methods was used to construct a robust list of disease-related feature genes. These prominent feature genes were validated in the training set and further externally confirmed using the GSE57218 dataset. Additionally, the CIBERSORT algorithm was employed to quantify immune cell infiltration in the normalized gene expression data, selecting infiltration results with high reliability (P Results
DDIT3 and PFKFB3 were significantly downregulated in OA patients. DDIT3 was specifically associated with lipid metabolism, apoptosis, and inflammatory genes (e.g., TNFRSF12A), whereas PFKFB3 was linked to phospholipid synthesis and cell cycle genes (e.g., CHKA). Both genes were associated with core OA-related pathways, including PI3K-Akt and AGE-RAGE. Immune infiltration analysis revealed that DDIT3 was positively correlated with pro-inflammatory mast cells and M1 macrophages, while PFKFB3 was negatively correlated with activated dendritic cells. Collectively, these two genes were associated with immune cell infiltration patterns. The competing endogenous RNA (ceRNA) network analysis indicated that DDIT3 was associated with axes such as LINC00689-miR-769-5p, and PFKFB3 was associated with complex networks like GAS6-AS1-miR-146a-5p.
ConclusionDDIT3 and PFKFB3 are key candidate genes associated with the pathological progression of OA. Their downregulation is correlated with inflammatory and metabolic disturbances in chondrocytes, supporting their potential use as diagnostic biomarkers and therapeutic targets for OA.

Bone loss occurs in astronauts during prolonged spaceflight, thus indicating the sensitivity of skeletal homeostasis to altered gravitational environments. Previous studies have shown that microgravity affects osteoclast differentiation and bone resorption, which suggests that osteoclasts possess mechanisms to sense and respond to gravity-generated mechanical forces. For testing of the related mechanisms, hypergravity can be experimentally reproduced with use of a centrifuge. In the present study, osteoclasts derived from mouse bone marrow were subjected to hypergravity under three conditions: 30G exposure using a non-CO2 centrifuge system, and short- or long-term exposure to 3G or 5G using an incubator-compatible centrifuge system. Cytoskeletal organization and resorptive function were assessed using TRAP (tartrate-resistant acid phosphatase) staining, F-actin visualization, and dentin pit assays. In addition, phosphoproteomic analysis was performed after short-term exposure to 5G hypergravity. Hypergravity exposure for as brief as 30 minutes compromised F-actin ring integrity, reduced fluorescence intensity, and promoted nuclear repositioning toward actin rings, whereas tubulin and vinculin localization remained unchanged, and the structural alterations corresponded to attenuated resorption pit formation. Quantitative phosphoproteomic profiling revealed coordinated hypergravity-dependent changes in phosphorylation across multiple cellular modules, including cytoskeletal organization, membrane trafficking, intracellular signaling, and nuclear regulatory pathways. Together, these results indicate that osteoclasts are sensitive to gravity-generated mechanical loading, with hypergravity rapidly modifying F-actin-associated cytoskeleton properties and reprogramming phosphorylation-dependent signaling networks, ultimately attenuating bone-resorptive activity. These findings provide mechanistic insight into how osteoclasts respond to altered gravitational loading conditions and have implications for skeletal adaptation during spaceflight and under altered mechanical loading conditions on Earth.by Tatsuya Yoshihara, So Owada, Harumasa Arita, Akiko Nakagomi, Kota Tanaka, Yosuke Ono, Osamu Yoshino
BackgroundTo investigate the association between menstrual-related disorders and sexually transmitted infections (STI) among young women in Japan, and to examine differences according to disorder type and hormonal therapy use.
MethodsThis cross-sectional study used the Japan Medical Data Center Claims Database and included women younger than 40 years who had at least one healthcare visit in 2023. Menstrual-related disorders were defined as endometriosis or dysmenorrhea based on ICD-10 codes. The prevalence of five STIs—gonorrhea, genital chlamydia infection, trichomoniasis, genital herpes, and other sexually transmitted conditions—was compared between women with and without menstrual-related disorders. Subgroup analyses were conducted for endometriosis, dysmenorrhea, and hormonal therapy (low-dose estrogen–progestin combinations or dienogest). Prevalence ratios (PR) and prevalence differences (PD) with 95% confidence intervals (CI) were estimated.
ResultsAmong 3,440,929 women, 257,897 (7.5%) had menstrual-related disorders. All STI were substantially more prevalent in this group than in women without menstrual-related disorders, with PRs ranging from 4.31 to 5.29. Endometriosis showed the highest prevalence, particularly for genital chlamydia infection (4.98%; PR 7.44). Dysmenorrhea was also associated with consistently elevated STI prevalence. Among women with menstrual-related disorders, STI prevalence differed only slightly according to hormonal therapy use, with differences generally within one percentage point.
ConclusionMenstrual-related disorders were strongly associated with increased diagnosis of STI in Japanese young women. These findings highlight the importance of integrating STI screening and reproductive health education into routine gynecologic care for women with endometriosis or dysmenorrhea. The influence of healthcare-seeking behavior and diagnostic patterns should be considered when interpreting claims-based STI data.
To develop predictive models for early and overall tuberculosis (TB) deaths for prospective use at TB diagnosis in resource-constrained TB programme settings.
Statewide cohort study using routinely captured secondary data.
With the majority of TB deaths being early (within 2 months), India’s TB programme’s information management system (Ni-kshay)-dependent death prediction models (using age, gender, TB site, previous treatment, microbiological confirmation, HIV, diabetes and bank account availability) are not feasible for prospective use, as few variables are captured at diagnosis. Utilising routinely captured triage variables for severe illness at diagnosis (body mass index, pedal oedema, respiratory rate, oxygen saturation and ability to stand without support) from an ongoing statewide and state-specific differentiated TB care initiative to reduce TB deaths in Tamil Nadu state (southern India, 80 million population with 0.1 million annual notifications), robust models for prospective use were developed.
Adults (aged ≥15 years) with TB (not known to be drug-resistant at diagnosis) that were notified from public facilities of Tamil Nadu from July 2022 to June 2023.
Early and overall (within 12 months of notification) TB deaths. Area under the receiver operating characteristic curve (AUC) was used to assess accuracy of models built using modified Poisson regression.
Among 55 971 adults, the overall death rate was 7.4%, and 67.9% of the deaths were early. In predicting overall deaths, accuracy of the model using all Ni-kshay variables (AUC 0.716 (95% CI 0.707 to 0.725)) was as good as the model using triage variables for severe illness only (AUC 0.701 (95% CI 0.691 to 0.711)). To the latter, adding potentially capturable Ni-kshay variables at diagnosis (age, gender, TB site, previous treatment and microbiological confirmation) significantly improved model accuracy (AUC 0.754 (95% CI 0.745 to 0.763)). Further addition of remaining Ni-kshay variables did not improve accuracy significantly. Death prediction equations were generated for these models.
Simple and easily measurable triage variables for severe illness should be routinely captured at TB diagnosis. A death prediction calculator (http://44.208.93.99/) based on these variables (specifically triage variables for severe illness combined with age, gender, TB site, previous treatment and microbiological confirmation) may be used by Indian states and high TB burden countries seeking scalable, data-driven interventions to reduce TB deaths.
This study aimed to explore the dual perspectives and challenges of clinical nursing educators and novice nurses regarding the implementation of nursing-specific mini-clinical evaluation exercise (mini-CEX) and direct observation of procedural skills (DOPS) in novice nurses’ training within a single tertiary hospital in China.
A descriptive qualitative research design was used. Participants were selected using a purposive sampling method, and semistructured interviews were conducted to collect data, which were then analysed following the six-step thematic analysis process.
The study was conducted at a tertiary hospital in Beijing, China.
A total of 24 participants were recruited from November to December 2023, comprising 13 clinical nursing educators and 11 novice nurses.
Four themes emerged: (1) novice nurse growth: true reflection of novice nurses’ clinical nursing abilities through direct observation; tailored learning pathways for individual growth; immediate feedback and self-reflection-driven engagement for individualised learning advancement; visual analytics for identifying targeted improvement areas and tracking progress across clinical domains; (2) educator teaching quality: practical contents and flexible methods of evaluation; real-time teaching adaptation and refined teaching plans; educator-led multidimensional nursing competencies cultivation; (3) obstacles in implementing evaluation tools: time-consuming processes in assessment and manual documentation; insufficient and delayed feedback due to heavy clinical workload; interruption of implementation by significantly changed clinical situation and (4) factors affecting implementation efficacy: subjective differences in scoring and inconsistent evaluation standards; lack of specialty in assessment tools; teaching-related factors; novice nurses’ personal factors; patient-related factors; feedback-related factors.
Educators and novice nurses perceived that the nursing-specific mini-CEX and DOPS have many advantages but raise concerns about time-consuming assessments, inadequate or delayed feedback, disruptions to implementation due to significant clinical changes, inconsistent standards and a lack of specialised assessment tools as well as multiple factors affecting its efficacy. Future research should focus on efficient strategies for optimal use.

PurposeSpinal cord injury (SCI) impacts physical, emotional, and social well-being, contributing to decreased quality of life and increased healthcare burden. Surface electromyography (sEMG), a non-invasive tool for measuring muscle activity, has demonstrated potential as a biomarker for recovery in SCI research, yet remains underutilized in clinical practice. Understanding how physical therapists (PTs) and occupational therapists (OTs) perceive the use of sEMG is necessary for integrating sEMG into post-SCI treatment and advancing personalized rehabilitation.
Materials and methodsA cross-sectional, qualitative descriptive design was employed. Ten participants (9 PTs and 1 OT) were recruited through convenience sampling. Semi-structured interviews were conducted and analyzed inductively using a thematic analysis approach.
ResultsTwo major themes were identified: 1) Perceived value of the use of electrophysiology and sEMG data in clinical practice. Participants valued sEMG as an adjunct assessment tool for providing objective feedback after incomplete SCI and setting goals during treatment. 2) Barriers and facilitators to implementing sEMG. Key barriers highlighted include the lack of training and standardized protocols. Continued training, resources, and educational support were key facilitators.
ConclusionPTs and OTs perceive sEMG as a valuable tool in SCI rehabilitation, but desire education and standardized protocols to support its clinical integration.

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.by Linda Furness, Janani Pinidiyapathirage, Matthew French, James Ware, Liam Weber, Brendan Carrigan
IntroductionIn rural generalist clinical settings, medical trainees routinely assess patients and discuss their findings with supervisors to plan ongoing care. These interactions termed ‘learning conversations’, serve as important opportunities for workplace-based learning and clinical decision making. However, preliminary evidence and stakeholder feedback indicate a lack of shared understanding regarding how these conversations should be structured, facilitated, and optimised. This study aims to observe current practices, identify supervisor and trainee learning needs, and co-design a model of learning conversations that enhances educational value and supports safe, effective patient care.
Methods and analysisThis study will use an exploratory sequential mixed methods design structured around the 3Cs of co-design (Co-define, Co-design, Co-refine). Phase 1 (co-define) will involve qualitative observation and audio-recording of learning conversations across two rural hospitals to characterise current practice and inform a protype model. In Phase 2 (co-design), supervisor and trainee focus groups will explore perceived needs, expectations, and feedback on the prototype model. A national online survey of rural supervisors and trainees will further inform model refinement. Phase 3 (co-refine) will incorporate national stakeholder input through a workshop, followed by feasibility testing of the refined model during a pilot simulation at a Rural Clinical School. Outcome data will focus on model usability, perceived relevance, applicability across contexts, and users’ experiences of employing the model during simulated learning conversations.
DiscussionThis study will produce a stakeholder-informed model that responds to the specific learning and clinical needs of rural generalist practice. By embedding co-design throughout the research process, the resulting model is expected to strengthen learning conversations, optimise trainee learning, and enhance the quality and safety of patient care. The findings have potential applicability across broader health professional training contexts and can support workforce development in rural healthcare settings.

IntroductionGlycemic dysregulation is a hallmark of type 2 diabetes (T2D) and contributes to skeletal muscle (SKM) loss and frailty risk, especially in older adults. Glycemic control and physical function are supported by SKM capillarization and mitochondrial function, and their impairment contributes to T2D development. While high-intensity interval training (HIIT) is a promising intervention, adherence and effectiveness remain concerns for prescribing HIIT among older adults at risk for T2D. Local heat therapy (LHT) may be a more practical initial strategy to improve SKM architectural factors and precondition SKM, enhancing physiological adaptations to exercise in this population.
Methods and analysisHeat and Exercise in Aging as Therapy (HEAT) is a two-phase, randomized, sham-controlled clinical trial investigating the efficacy of LHT to improve glycemic control and decrease frailty risk via improved SKM architecture among older adults with prediabetes. LHT is tested as a standalone intervention and as a means to precondition SKM for subsequent HIIT, improving exercise adaptations. In Phase 1, LHT and sham (CON) groups apply heat pads for 90 minutes/day, 6 days/week, for 12 weeks. A separate HIIT group completes 4x4-minute cycling intervals at 90–95% VO₂peak, 3 days/week. In Phase 2, LHT and CON groups begin HIIT. Participants (≥50 years) have impaired fasting glucose (100–125 mg/dL) and/or HbA1c (5.7–6.4%). Biospecimen collection and clinical assessments occur at baseline (T1), after Phase 1 (T2), and Phase 2 (T3). To our knowledge, this is the first study to determine the use of local heat pad on pre-diabetic older population. If successful, LHT may be a practical, scalable, non-invasive intervention to improve glycemic control and reduce frailty risk in older adults with prediabetes, preventing progression to T2D.
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.
Scaling and root planing (SRP) combined with adjunctive antibiotic therapy is widely adopted in the management of periodontitis in patients with type 2 diabetes mellitus (T2DM), with the aims of ameliorating glycaemic control, alleviating local inflammation and facilitating periodontal tissue regeneration. As a topically administered adjunctive antibiotic for periodontal treatment, minocycline hydrochloride (MH) ointment has shown favourable clinical efficacy in systemically healthy patients with periodontitis. However, robust evidence supporting its clinical efficacy and potential glycaemic-improving effects in patients with periodontitis complicated by T2DM remains limited. The present study is designed to test the null hypothesis that no significant differences in clinical outcomes exist between SRP combined with MH and SRP alone in the management of periodontitis among patients with T2DM, with its primary objective to investigate whether MH as an SRP adjunct confers superior clinical benefits to SRP alone.
We will conduct a randomised, single-blind, placebo-controlled clinical trial. 56 patients with T2DM-associated stage III/IV periodontitis will be recruited from the Department of Periodontology, Peking University School and Hospital of Stomatology, Beijing, China. Eligible participants will be randomised into two groups: the experimental group will undergo SRP combined with topically administered MH ointment and the control group will undergo SRP with a matched placebo. The primary outcomes will include probing depth (PD) changes at periodontal pocket sites with a baseline PD ≥6 mm at 6 months post-baseline, with a specific focus on the percentage of such sites with PD reduced to ≤5 mm. The secondary outcomes will comprise PD changes at pocket sites with a baseline PD ≥5 mm at 6 months post-baseline, as well as clinical attachment loss, the plaque index, bleeding index, the levels of IL-1β, IL-17, calprotectin and insulin levels in gingival crevicular fluid and serum, complete blood count, blood biochemistry, including glycated haemoglobin levels, and the composition of subgingival plaques at baseline, and 2 and 6 months post-baseline.
This study was approved by the Ethics Committee of Peking University School and Hospital of Stomatology (PKUSSIRB-2024102139b). Results will be published in a peer-reviewed scientific journal.

Despite implementation of the National Programme for Prevention and Control of Non-Communicable Diseases (NP-NCD), screening coverage for oral, breast and cervical cancers remains below 2%. Screening quality is inadequately addressed and delays in diagnosis and treatment initiation continue to persist. This multisite implementation research aims to improve district-level coverage and quality of screening, early diagnosis and timeliness of treatment initiation through a model co-developed within the NP-NCD context.
The study will be conducted in three phases across seven districts in diverse regions of India. In phase I (formative), the current status, barriers and facilitators of cancer screening, diagnosis and treatment initiation under NP-NCD will be assessed. In phase II (optimisation), a model (package of implementation strategies) will be co-developed and iteratively optimised with multistakeholder engagement at the subdistrict level to improve screening coverage and quality and strengthen the referral system for early diagnosis and treatment initiation. In phase III (scale-up and evaluation), the model will be implemented at the district level and evaluated for improvements in screening, early diagnosis and treatment initiation. A convergent mixed-methods design will be used, incorporating household surveys, facility assessments and stakeholder interviews. Implementation Research Logic Model will guide planning, execution and evaluation in the present study. Determinants of screening coverage and quality, early diagnosis and treatment initiation will be assessed using the Consolidated Framework for Implementation Research. Implementation strategies for the model will be finalised using the Expert Recommendations for Implementing Change framework. Implementation and service outcomes will be evaluated using the Reach, Effectiveness, Adoption, Implementation and Maintenance framework.
Ethical approval has been obtained from all study sites. The study findings will be disseminated at the state, national and global levels through meetings and conferences and submitted to a peer-reviewed journal for publication.

Ophthalmic complaints account for a substantial proportion of presentations to emergency and acute eye care services, yet initial assessment or referral is frequently performed by non-ophthalmologist healthcare professionals. Previous single-centre studies suggest that one-third of referrals are incorrectly diagnosed, potentially delaying appropriate management of vision-threatening conditions. However, the overall magnitude of diagnostic error and patterns of misdiagnosis across healthcare settings remain unclear. This study aims to systematically review and synthesise the evidence on the diagnostic concordance of ophthalmic referral diagnoses made by non-ophthalmologists in acute eye care.
A systematic review and meta-analysis will be conducted following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocols) guidance and registered with PROSPERO. MEDLINE (Ovid), Embase (Ovid) and the Cochrane CENTRAL database will be searched from inception to April 2025. Studies evaluating the diagnostic accuracy of referrals made by non-ophthalmologist healthcare professionals in emergency or acute eye care settings will be included. Two reviewers will independently screen studies, extract data and assess risk of bias using the QUADAS-2 (Quality Assessment of Diagnostic Accuracy Studies-2) framework adapted for referral-diagnosis studies. The primary outcome will be diagnostic concordance between referral and final ophthalmologist diagnosis. Where appropriate, pooled concordance proportions will be synthesised using a random-effects meta-analysis. Condition-specific 2x2 diagnostic accuracy analyses will only be undertaken where valid binary target conditions and sufficient denominators are reported. Heterogeneity will be assessed using Cochran’s Q test and the I² statistic with subgroup analyses exploring differences by referring clinician type and anatomical location of ophthalmic pathology.
Ethical approval is not required for this study as it will synthesise data from previously published studies; findings will be disseminated through publication in a peer-reviewed journal and presentation at relevant academic conferences.

Sexually transmitted infections (STIs) have emerged as significant public health concerns, imposing a substantial burden on both individuals and the healthcare system of the country. Additionally, STIs may also result in major extensive psychological consequences that profoundly affect individuals with STIs. Despite the government’s implementation of different initiatives aimed at addressing STI-related challenges, these conditions are associated with shame and stigma which act as barriers to the effective utilisation of healthcare services. The purpose of the present study is to generate evidence on barriers and facilitators to service utilisation and management of STIs in India.
Indian Council of Medical Research, New Delhi, is conducting a multi-centre study employing a mixed-method approach. The study involves different levels of healthcare systems, including both government and private healthcare facilities across seven sites in several states of India, including Maharashtra, Rajasthan, Punjab, Bihar, Uttar Pradesh and New Delhi. For the quantitative data, individuals seeking healthcare services related to STIs will be enrolled and assessed using a semi-structured pilot-tested questionnaire. In-depth interviews and focus group discussions will also be conducted with different stakeholders as per the standard guidelines of the qualitative method by the designated trained project staff. Descriptive and inferential statistics will be applied to the quantitative data, while the qualitative data will be analysed using a deductive approach with thematic content analysis.
The study protocol has been approved by the ethics review committees of all the participating sites individually. The findings from this study will be published in peer-reviewed journals and disseminated through scientific conferences and meetings among policy-makers and government agencies.

Neoadjuvant chemotherapy (NAC) followed by definitive treatment consisting of either radical radiotherapy or radical cystectomy is the recommended treatment for patients with organ-confined muscle-invasive bladder cancer (OC-MIBC). A randomised controlled trial (RCT) aimed to compare the effectiveness of radical radiotherapy and radical cystectomy but failed to recruit. Radical radiotherapy is non-invasive and organ-preserving, and observational studies have suggested this treatment may be associated with similar outcomes compared with radical cystectomy. However, in these observational studies, the risk of confounding was high, and they did not consider the receipt of NAC. The surgery or radiotherapy (SORT) for the early-stage cancer study will assess the comparative effectiveness and cost-effectiveness of either radical cystectomy or radical radiotherapy, both after NAC for OC-MIBC. We will use a target trial emulation approach to reduce the risk of bias when assessing comparative effectiveness from observational data.
The SORT study will use UK’s National Cancer Registry to identify individuals diagnosed with urothelial OC-MIBC (T2-4aN0M0) between 1 January 2015 and 31 December 2021 who received either radical radiotherapy or radical cystectomy after NAC. The data will be linked to Hospital Episode Statistics (HES), National Radiotherapy Data Set (RTDS) and Systemic Anti-Cancer Therapy (SACT) data sets to gather information on clinical, tumour and socio-demographic characteristics and receipt of treatment. Using the target trial emulation framework, we will define the eligibility criteria and radical radiotherapy and radical cystectomy receipt. To reduce the risk of confounding, we will use advanced statistical approaches to allow for differences in measured baseline characteristics between the comparison groups.
The primary outcome is 3-year all-cause mortality after radical treatment receipt. Secondary outcomes will include all-cause and bladder-cancer-associated mortality at 3 and 5 years, time to death, incremental costs and incremental cost-effectiveness reported according to net health benefits.
The study was approved by the London School of Hygiene and Tropical Medicine Ethics Committee (Reference number 29717 - 1). Results will be communicated in open-access journals and conferences to clinicians, researchers, patients and policymakers.
This study aimed to investigate the association of the triglyceride-glucose (TyG) index with the risk of acute myocardial infarction (AMI) and all-cause mortality in patients with coronary artery disease (CAD), and to inspect whether AMI mediates the relationship between TyG index and mortality.
A large-scale, retrospective cohort study.
This single-centre study was conducted at a tertiary academic hospital in South China. The association between the TyG index and AMI was assessed using multivariable logistic regression, with progressive adjustment for demographic and clinical covariates. Cox proportional hazards models were used to estimate the HRs for all-cause mortality associated with TyG index. Restricted cubic splines and mediation analysis were employed to examine non-linear relationships and the mediating role of AMI.
A total of 20 125 patients diagnosed with CAD during hospitalisation between January 2020 and February 2025 were initially enrolled. After applying exclusion criteria (insufficient data), 18 245 participants were included in the final analysis.
We examined the association of the TyG index with the risk of AMI, as well as its association with all-cause mortality across different CAD subgroups.
The association between the TyG index and all-cause mortality was significantly modified by AMI status (P for interaction
An elevated TyG index independently predicts the risk of AMI in patients with CAD. Its prognostic value for mortality, however, is critically dependent on the presence of AMI: while a higher TyG index is associated with increased mortality in patients with AMI, moderately elevated TyG levels (Q2–Q3) are associated with lower mortality, whereas the highest quartile shows no significant association. Mediation analysis further reveals that AMI significantly mediates the association between TyG index and mortality, highlighting the importance of AMI prevention in mitigating the adverse prognostic impact of insulin resistance in the CAD population. These findings warrant validation in prospective studies.
