To assess the quality of the Spanish Triage System performed by nurses according to the triage code assigned to each patient and to examine factors associated with the need for re-evaluation after completion of triage.
Retrospective longitudinal observational study.
A retrospective analysis was conducted of patients triaged in the emergency department between 2018 and 2023. Patients triaged by other healthcare professionals and those who did not receive a triage priority level were excluded.
493,211 episodes were analysed. Most were low/intermediate acuity (Level IV 65.4%, Level III 23.9%; Level I 0.1%). Mean time-to-first physician record entry increased as acuity decreased (38 min Level I vs. 81 min Level V), yet recorded time-target compliance was lowest in Levels I–II (23.8% and 14.7%). Re-evaluation occurred more often in high-acuity levels and was independently associated with older age, male sex, lower oxygen saturation and longer emergency department length of stay; compared with Level I, Levels II–III and lower adjusted odds of re-evaluation.
Nurse-led triage demonstrated coherent clinical and operational stratification; however, the lowest recorded time-target compliance in the sickest patients suggests a gap between immediate care and electronic documentation.
Streamline documentation workflows for high-acuity cases and use re-evaluation risk profiles to prioritize monitoring and escalation.
Evidence on nurse-led Spanish Triage System performance and time-documentation quality is limited. Acuity and flow metrics showed expected gradients, but target-time compliance was lowest in Levels I–II; predictors of re-evaluation were also identified. Findings support emergency department nursing, quality improvement and potential benefits for patients attending emergency departments.

To assess the level of alarm fatigue among intensive care unit (ICU), cardiac care unit (CCU) and emergency room (ER) nurses, identify associated demographic and occupational factors, determine the most frequent sources of alarms and evaluate nurses’ psychological reactions to alarms.
A cross-sectional, descriptive–analytical study.
ICUs, CCUs and ERs of six public teaching hospitals affiliated with Tehran and Kashan Universities of Medical Sciences in Iran.
Using a multistage stratified random sampling method, 285 nurses were approached, of whom 260 completed and returned the questionnaires (response rate: 91%). Participants were registered nurses with at least a bachelor’s degree or higher and 3 months of experience in ICUs, CCUs or ERs.
The primary outcome was the level of alarm fatigue measured using the validated Nurses’ Alarm Fatigue Questionnaire. Secondary outcomes included factors associated with alarm fatigue and nurses’ reported psychological responses to frequent alarms.
The mean score of alarm fatigue was 26.4±7.9, indicating a moderate level. After adjusting for confounders and hospital-level clustering using multivariable mixed-effects regression, higher monthly income was significantly associated with lower alarm fatigue (β=–0.15, p=0.03), and nurses working rotational shifts reported significantly higher fatigue compared with those with fixed shifts (β=0.18, p=0.02). Other demographic and occupational factors were not significant. Reported psychological reactions to alarms included indifference (14%), irritability (18%) and anxiety/stress (15%).
ICU, CCU and ER nurses experience a moderate level of alarm fatigue, with income and shift type as independent associated factors. The association between income and alarm fatigue may reflect the role of financial stress as an additional job demand that compounds the burden of frequent alarms, particularly in contexts where low base salaries lead nurses to rely on overtime and multiple shifts. These findings underscore the need for targeted managerial and educational interventions, including shift schedule optimisation and attention to workload-related stressors, alongside alarm prioritisation strategies. Due to the cross-sectional design, causal inferences cannot be drawn.

BackgroundDeath anxiety is fast becoming recognised as a transdiagnostic construct across myriad mental health conditions. Though existing clinical treatments of death anxiety, such as Cognitive Behaviour Therapy type interventions, have been shown to be effective, Terror Management Theory (TMT) proposes self-esteem as a protective factor against death anxiety by endowing individuals with a feeling of significance in life and helping them to process the nature of death and its inevitability. Despite the centrality of self-esteem to TMT, however, extant research examining its relationship with death anxiety has yet to be synthesised. The current study aims to systematically review peer-reviewed, quantitative research examining the association between death anxiety and self-esteem and, where possible, to test the strength of these associations through meta-analysis.
MethodA systematic search of quantitative and mixed-methods studies will be conducted across six databases: MEDLINE; PsycINFO; PubMed; Web of Science; CINAHL and; EMBASE. Google Scholar will also be searched and the first 200 records by relevance will be screened for eligibility. Searches will be conducted by TC, and records will be screened by TC, SK, CF, RH and KB, so that each record is screened for eligibility by at least two authors. Data extraction and quality assessment, using the Joanna Briggs Inventory Risk of Bias tools, will be performed by TC, SK, CF, RH and KB, so that each record is assessed by at least two authors, with doubts and discrepancies being resolved through discussion with AS and MM. A narrative synthesis of relevant data will be presented and, where sufficient data are available, meta-analysis will be conducted using the MAJOR extension for Jamovi to establish an overall effect size for the association between death anxiety and self-esteem. Should sufficient data be available, demographic factors, such as gender and age, and clinical population status (clinical vs. non-clinical population) will be examined as moderators of the effect. This protocol was developed in line with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and has been registered in PROSPERO (CRD42024591775).
DiscussionThe current review will systematically examine the relationship between death anxiety and self-esteem. Should sufficient data be available, an overall effect size of the relationship will be generated. By better understanding how death anxiety is related to self-esteem, and by establishing the size and significance of the relationship will aid firstly in systematically validating TMT and, secondly, identify whether self-esteem may be targeted in future death anxiety interventions to reduce death anxiety and improve individuals’ overall mental health.

Hepatocellular carcinoma (HCC) has a very significant mortality rate and is one of the most common cancers worldwide. Jacaranda mimosifolia is reported to have potential antitumor activities against various human cancers. However, the effects of J. mimosifolia on HCC are yet elusive. This study aimed to investigate the anti-HCC potential of methanolic extract of J. mimosifolia leaves using in vitro and in vivo studies and a network pharmacology approach. The effect of J. mimosifolia extract was assessed on Huh-7.5 cells using MTT assay, wound healing assay, and DNA fragmentation assay. These experiments found that J. mimosifolia extract significantly suppressed Huh-7.5 cell proliferation, impaired cell migration, and induced cell apoptosis. The real-time PCR validated the upregulation of p53 and Bax, alongside the downregulation of AFP and GPC3 in Huh-7.5 cells after treatment with J. mimosifolia extract. In vivo experiments confirmed the hepatoprotective effects of J. mimosifolia extract in mice models with CCl4-induced hepatic injury. In addition, through network pharmacological analysis, J. mimosifolia was found to play a critical role against HCC via targeting multiple potential targets and pathways. Docking analysis identified apigenin and kaempferol with the lowest binding energy against PTGS2 and EGFR, respectively, while flavonol glycoside showed the lowest binding energy against MMP9. However, detailed research is needed to isolate the potential phytochemicals from J. mimosifolia against HCC.To map and synthesise the main recommendations for arterial blood gas (ABG) collection in intensive care units (ICUs).
A scoping review was conducted according to the PRISMA-ScR Checklist, supported with The PAGER framework and guided by the Joanna Briggs Institute methodology to ensure methodological rigour and analytical comprehensiveness.
Data collection was conducted from February to April 2024. The data sources included: Cumulative Index to Nursing and Allied Health Literature (CINAHL), Cochrane Library, PubMed Central, Scientific Electronic Library Online (SciELO), Web of Science (WoS), SCOPUS, Science Direct, Virtual Health Library (VHL), Excerpta Medica database (Embase), CAPES Thesis and Dissertation Catalogue, Brazilian Digital Library of Theses and Dissertations (BDTD), Scientific Open Access Repository of Portugal (RCAAP), Theses Canada and the Oswaldo Cruz Foundation (Fiocruz) repository.
Key findings recommend the radial artery as the preferred puncture site, an insertion angle of 30° to 45°, the use of 1 or 3 mL syringes and 20G or 23G gauge needles. Transport and storage at room temperature are advised. Cryoanalgesia and subcutaneous analgesia methods were found to be effective for pain management.
The review highlights the best practices for arterial blood gas collection in critical care. The synthesized evidence strengthens clinical practice, informs guidelines for intensive care nursing and promotes safer, higher-quality care for critically ill patients.
The evidence-based recommendations identified can enhance nursing care related to arterial blood gas collection. Adherence to these practices promotes safer, more humanised and evidence-based care during the procedure.
The report of this study followed the PRISMA-ScR Checklist.

This study evaluated the effects of increasing narasin doses on ruminal fermentation, nutrient digestibility, ruminal pH stability, papillae histology, and microbial composition in Angus cattle fed feedlot diets. Three rumen-cannulated Angus steers (average body weight: 680 kg) were assigned to a 3 × 3 Latin square design and received diets containing 13, 20, or 27-ppm of narasin. Each experimental period consisted of 14 days of adaptation followed by seven days of sampling. Ruminal degradability was assessed on days 15–17, apparent digestibility on days 15–19, continuous ruminal pH on days 19–20, and samples for short-chain fatty acids (SCFA), microbiota, and ruminal histology were collected on days 20 and 21. Ruminal degradability was not affected by narasin dose. Digestibility of acid detergent fiber (ADF) was significantly influenced, with the greatest values observed at 27-ppm (P = 0.01). Increasing narasin doses improved ruminal pH stability, as indicated by a linear increase in minimum pH (P = 0.01) and a reduction in the duration of pH below 5.6 (P = 0.10). At 13 ppm, SCFA production, particularly acetate and propionate, increased (P P P = 0.02), and butyrate (P P P = 0.03). Narasin supplementation altered ruminal microbial composition, increasing the relative abundance of Lachnospiraceae and Isotricha while reducing lactic acid–producing bacteria. In terms of ruminal morphology, supplementation with 20-ppm of narasin increased the keratin layer thickness of ruminal papillae (P = 0.02), suggesting enhanced epithelial development. Overall, narasin supplementation modulated ruminal function and microbial ecology, with doses between 13 and 20-ppm providing the most favorable balance between fermentative efficiency and ruminal health in feedlot cattle.Knee osteoarthritis (KOA) is a prevalent degenerative joint disorder, often accompanied by comorbidities like type 2 diabetes mellitus (T2DM). These conditions have a significant impact on patients’ sleep quality and metabolic health. Current treatments for KOA primarily focus on symptom management, while innovative approaches targeting interconnected health outcomes remain underexplored. The lumbar knee recovery device, a non-invasive device patented in Iran, offers potential benefits by enhancing lumbar-knee synchronisation, improving blood circulation and optimising cellular metabolism. This randomised controlled trial (RCT) aims to evaluate the device’s effectiveness in improving sleep quality and regulating blood glucose levels in diabetic patients with KOA.
This RCT aims to evaluate the impact of using the lumbar knee recovery device (Kamarasa) on sleep quality, blood glucose levels, HbA1c (blood glucose control level over the past 90 days) and body mass index (BMI) in patients with T2DM and grade 1–3 KOA. The study will be conducted at the Orthopedic Clinic of Imam Khomeini Hospital, Tehran, and the Health and Wellness Clinic. Eligible participants will be randomly allocated into two groups: the intervention group (receiving 10 supervised sessions using the Recovery device over 3 months) and the control group (receiving standard KOA and diabetes care). A total of 37 participants will be included in each group. The primary outcome, sleep quality, will be assessed using the Pittsburgh Sleep Quality Index at baseline and 3 months post intervention. Secondary outcomes will include random blood glucose levels, which will be measured at 10 intervals during the study; BMI, measured at the start and end of the study and HbA1c, assessed at both baseline and post intervention. The Western Ontario and McMaster Universities Arthritis Index will be used to assess pain, stiffness and physical function, also at both baseline and 3 months. Appropriate statistical tests, including two-sample t-tests, ² tests, analysis of covariance or linear regression, will be performed based on the type of variables using SPSS V.23. Additionally, standardised intervention effect sizes will be calculated for each outcome.
Ethical approval for this study was obtained from the Research Ethics Committee of the School of Nursing and Midwifery at Tehran University of Medical Sciences with reference number (IR.TUMS.FNM.REC.1403.145). Additionally, the study protocol was registered with the IRCT under the identifier IRCT20191027045257N7 on 24 November 2024.

The clinical practicum is a critical component of nursing education. In Spain, it is currently facing systemic challenges that compromise its quality and sustainability. A persistent nursing shortage, combined with increasing pressure on healthcare systems and a growing number of students intended to address this gap, is adding strain to clinical learning environments, which may compromise the capacity of nurses to provide adequate supervision and meaningful learning experiences for nursing students. This not only diminishes the quality of the training experiences, but also negatively affects the well-being of both students and nurses, further worsening the situation. This protocol outlines a study aimed at conducting an in-depth analysis of the current challenges affecting the clinical practicum and proposing a new model that effectively addresses them, with significant potential for adaptation and implementation across different health education fields and geographical locations.
The study will employ a sequential mixed-methods design comprising two integrated phases. In phase I, quantitative, qualitative and scoping review methodologies will be combined to identify current challenges and opportunities. Quantitative data will be obtained by administering questionnaires to nursing students and clinical mentors (CMs) tutoring them in Catalonia, examining potential barriers and facilitators to their mentoring role. Data will be analysed through descriptive and inferential statistics. Qualitative data will emerge from semistructured interviews with CMs and nurse coordinators, as well as from a visual elicitation technique, the ‘Emojional’ Calendar, conducted with students to understand their clinical practicum experiences. These will be analysed through an inductive thematic analysis approach. The scoping review, following the Arksey and O’Malley framework, will identify best practices in clinical practicums in nursing and other health studies globally. Phase II will involve a three-round qualitative Delphi study in which all preceding results will be presented to stakeholders and decision makers in order to redesign the clinical practicum model.
Ethical approval for this study was obtained from Hospital del Mar Clinical Research Ethics Committee (Ref #2023/11123). Results will be disseminated through peer-reviewed journals and conference presentations, as well as via strategic actions (forums and meetings with healthcare managers, deans and policymakers) and general outreach (talks, social media and websites) targeted at professionals, students and the public.
Patient decision aids (PtDAs) are effective interventions to support patient involvement in health decisions and have the potential to impact favourably on health inequities by reducing gender bias in clinical practice. The aim was to explore sex and gender reporting and differences in randomised controlled trials (RCTs) evaluating PtDAs for adults making treatment or screening decisions.
Secondary analysis of the Cochrane review of PtDAs of RCTs that reported sex and/or gender. The original review searched MEDLINE, Embase, PsychINFO and EBSCO from journal inception to March 2022. Two team members independently screened citations, extracted data and assessed risk of bias. For this secondary analysis, we only included primary outcomes from the original review. We assessed appropriate use of terminology for sex (biological attribute) and gender (social construct). When terms were used interchangeably, it was considered inaccurate. Findings were synthesised descriptively, and we used meta-analysis when two or more RCTs were conducted with females/women or males/men using similar outcome measures.
Informed values-choice congruence and the quality of the decision-making process (eg, knowledge, accurate risk perceptions, feeling informed, clear values, participation in decision making, undecided) and adverse events (eg, decision regret, emotional distress) by sex and gender.
Of 209 RCTs in the original review, 206 reported sex and/or gender, with 35 (17%) using accurate terminology. Of 206 RCTs, 70 were with females/women only, 27 males/men only, 12 analysed by sex/gender and 97 RCTs did not disaggregate findings by sex or gender. Meta-analysis comparing RCTs for females/women to usual care and RCTs for males/men only compared with usual care showed similar mean differences in knowledge scores (10.84 vs 9.38 out of 100; p=0.44). Males/men had significantly higher self-reported participation in decision making compared with females/women (RR 3.16 vs 0.95; p
In PtDA RCTs, sex and gender terms are used interchangeably and 6% analysed outcomes by sex or gender. Meta-analysis of males/men only given PtDAs showed higher self-reported decision making participation in clinical practice compared to usual care versus females/women only compared with usual care. Researchers must improve reporting sex and gender in PtDA RCTs to assess how it influences health inequities.

Cadmium (Cd), a toxic heavy metal found in agricultural landscapes worldwide, has been pointed out in cropped soils with Theobroma cacao L., as one of the main contaminants that translocate into plant tissues. Among the factors linked to cadmium translocation into plants, the role of soil bacterial communities in chemical transformation in soils has been poorly investigated. Overall, soil bacterial communities are shaped by diverse environmental and anthropogenic factors that influence crop yield and health. Cadmium alters soil microbial communities and increases the risk to human health through plant uptake. Although the impacts of cadmium on soil bacteria have been studied in other crops, there is limited information on cacao. Thus, this study aimed to assess the responses of soil bacterial communities in cacao farms to cadmium exposure, both natural and spiked. A total of 225 rhizosphere soil samples were collected from 16 plots across five cacao farms in two Colombian departments. The complementary approaches used were: (i) 16S rDNA amplicon sequencing to assess the composition of the bacterial community in soils with natural Cd concentrations, and (ii) isothermal microcalorimetry (IMC) to measure the temporal metabolic responses of bacteria to Cd in closed systems for 80 hours at 25 °C. The findings suggest that nearly 28% of the bacterial community responds to high cadmium concentrations in soils, both in natural and experimental conditions. Field-based observations revealed that Cd-responsive taxa detected under natural soil conditions included several unculturable bacterial groups, whereas laboratory experiments with Cd spiking predominantly selected for previously characterized cadmium-tolerant bacteria (CdtB). Significant variation in natural Cd-bacterial community composition and Cd-related metabolic activity was observed across the farms. Moreover, Cd-responsive bacterial taxa exhibited increased abundance during Cd spikes. As expected, contrasting patterns were revealed by the activity-response measured by IMC and taxonomic analyses of 16S rRNA gene sequences.Adverse pregnancy and perinatal outcomes (APPOs), including pre-term birth, pre-eclampsia and gestational diabetes, can result in maternal and neonatal morbidity and mortality, parental anxiety and increased healthcare costs. A better understanding of the causes of APPOs is essential to inform lifestyle and pharmaceutical interventions for their prevention and management. Given the difficulty of undertaking randomised controlled trials in pregnant women, triangulating evidence from across methods with different sources of bias may improve causal inference for APPOs. The purpose of the Mendelian randomisation in pregnancy (MR-PREG) collaboration is to support such triangulation using genetic (eg, Mendelian randomisation (MR)) and non-genetic (eg, partner negative controls) approaches to investigate the causal effects of maternal exposures on a comprehensive set of APPOs.
The MR-PREG collaboration includes individual participant data from three birth cohorts (two from the UK and one from Norway) and UK Biobank, as well as summary data from FinnGen and publicly available genome-wide association studies (GWAS). Data have been harmonised across studies and currently include information on up to 35 APPOs in up to 707 797 women.
The main aims of MR-PREG are to strengthen the evidence base for (1) prevention, by advancing understanding of maternal lifestyle factors on APPOs, (2) the role of pre-conceptional health, by improving understanding of the effect of maternal pre-existing conditions on APPOs, and (3) treatments, by evaluating the efficacy and safety of existing medications used for pre-existing conditions, and by identifying and testing novel or repurposed therapies for APPOs. To date, our published work has mainly addressed aims 1 and 3. Examples include triangulation of evidence from MR, conventional multivariable regression and paternal negative control, showing that higher maternal body mass index increases the risk of multiple APPOs, as well as the identification of maternal circulating metabolites and proteins that may influence birth weight.
Future priorities include increasing diversity within the MR-PREG collaboration by expanding representation of participants from non-European ancestries. We are also integrating molecular data, including circulating protein levels and placental transcriptomics, to better characterise the molecular mechanisms underlying APPOs. Additionally, we are using whole-exome and whole-genome sequencing to identify novel causal genes and to inform the prioritisation of candidate therapeutic targets for APPOs.
Increasing demand for haematological specialist care makes the optimisation of referrals and outpatient workflow a priority. Automated placing of standardised test orders prior to the first appointment may provide haematologists with necessary information to reach diagnoses and initiate treatment at the first patient encounter, reducing low-value follow-up appointments. We aimed to evaluate rates of patient participation in an initiative using artificial intelligence to place standardised test orders as well as reasons for non-participation, differences in the number of participants and non-participants discharged back to primary care with a diagnosis or appropriate treatment plan, and potentially avoidable referrals.
A retrospective, multicentric cohort study.
Four academic hospitals in Madrid, Spain.
18 190 patients referred for a first haematologist appointment for 11 included presenting complaints.
Referral notes from primary care were classified using natural language processing and automated placement of standardised test order sets was carried out prior to first appointment for participating patients.
We compared demographic differences between participants and non-participants, the main motives for not participating, and the number of patients discharged back to primary care at first appointment with a diagnosis and treatment plan. Most frequent International Classification of Diseases, tenth revision codes for each of the included presenting complaints were described.
During the study period, 18 190 (41%) patients were referred for a first haematologist appointment for presenting complaints included in the intervention (‘eligible patients’), of which 612 (3.3%) patients agreed to participate in the intervention. Participants were significantly younger than non-participants. Most common motives for not participating were administrative reasons (6268, 76.9%). Only 122 (1.5%) patients expressed explicit unwillingness to participate. A significant increase in the number of patients discharged upon first appointment was observed for participants (146 (23.9%) vs 3375 (19.36%); p=0.041), signifying a 22% relative reduction in avoidable follow-up. The diagnosis ‘haematological disorders ruled out’ was constantly observed as one of the ten most common diagnoses made by the haematology specialist for all but one of the included presenting complaints.
Natural language processing of referrals from primary to specialist haematology care with automated placing of standardised test orders can decrease low-value follow-up appointments. Explicit refusal to participate was low. Participants tended to be younger than non-participants, underlining the importance of designing strategies to target the older population in order to improve participation.
Outcomes for degenerative cervical myelopathy (DCM) patients are limited by delayed and missed diagnoses, driven in part by poor professional awareness. Despite DCM being the most common cause of adult spinal cord injury, it remains under-recognised and undertaught in clinical education. Lessons from other common pathology like stroke and acute myocardial infarction highlight the potential of education to improve early diagnosis. This study will develop a professional education strategy to improve early DCM diagnosis. It will define key audiences and identify an effective delivery method, laying the groundwork for a sustained, targeted intervention.
The study aims to define who needs to know about DCM, what they need to know and how they can learn it. This will be carried out in three phases: phase 1—who and what: to establish the target population and to define core competencies for the educational intervention; phase 2—how: to create and review the educational intervention; phase 3—evaluation: to test whether the framework is an improvement to existing strategies.
Ethical approval is in place from the University of Cambridge (HBREC.2024.24). Results from the study will be disseminated through scientific publication, conference presentation, blog posts and podcasts.

We aim to identify trajectories of probable maternal common mental disorders (CMD), as well as risk and protective factors associated with maternal mental health among postpartum women during the pandemic using life course theory approach.
Prospective individual level cohort study from the Iracema-COVID Study.
Mothers (n=335) at postpartum period who delivered during the COVID-19 pandemic in the fourth largest city in Brazil.
Probable CMDs were accessed using validated instruments in five cohort waves at postpartum period. Sequence analyses (SA) were employed to extract CMD trajectories, and a set of generalised binomial logistic and log-Poisson multivariable regression models with robust variance were employed to assess risk and protective factors for probable CMDs diagnosis.
Trajectories patterns of probable maternal common mental disorders.
Fit indices demonstrated a two-cluster-SA solution of probable CMD. The patterns of probable CMDs indicated that 335 mothers were clustered into occasional/transitory (n=240, 71.64%) and mostly/persistent (n=95, 28.36%) CMD trajectories. We found that mothers with low education (OR: 2.44; 95% CI 1.13 to 5.23), single (OR: 1.97; 95% CI 1.03 to 3.75) or in a stable union (OR: 2.00; 95% CI 1.02 to 3.90) and travel time spent to access the nearest primary healthcare unit (OR: 1.02; 95% CI 1.006 to 1.04) were associated with increased OR of belonging to the mostly/persistent CMD trajectory. Deprived green areas acted as a risk factor to maternal CMDs prevalence (OR: 1.37; 95% CI 1.002 to 1.87).
This study provides evidence that individual vulnerabilities and neighbourhood deprivation play an important role in understanding maternal mental health, beyond the patterns and trajectories of probable maternal CMD due to issues confronted during the COVID-19 outbreak in the northeastern region of Brazil. Policies to prevent and treat maternal mental health issues and improvement in neighbourhood deprivation need to be developed and addressed to avoid exacerbation of probable maternal CMDs.
Bipolar disorder affects around 2% of the population and is linked with reduced life expectancy and socioeconomic burden. Depressive episodes are difficult to treat and typically more prevalent, enduring and burdensome than manic episodes. The use of antidepressants alone has limited effect and is associated with significant clinical risk through polarity switch. Current National Institute for Health and Care Excellence guidelines recommend quetiapine, olanzapine (with or without fluoxetine) and lamotrigine; however, these medications have limited efficacy, tolerability and acceptability. The ASCEnD study aims to assess the clinical and cost-effectiveness of aripiprazole plus sertraline compared with quetiapine, offering potential improvements for outcomes in bipolar depression. The study is funded by the National Institute for Health and Care Research Health Technology Assessment programme (NIHR132773).
ASCEnD is a prospective, two-arm, superiority, individually 1:1 randomised, controlled, pragmatic, parallel group, type A open-label clinical trial of aripiprazole/sertraline medication combination compared with quetiapine for bipolar depression. The study is conducted in the UK National Health Service setting with the aim of recruiting and randomising 270 participants followed-up for 24 weeks. Adults with bipolar disorder self-refer or are recruited through primary and secondary care services. The primary outcome is change in depressive symptoms 12–16 weeks after randomisation. Secondary outcomes include measures of symptom change, treatment satisfaction, tolerability, medication adherence, concomitant medication use, psychosocial functioning, quality of life and cost-effectiveness and informal carer measures of quality of life and costs of caring. The exploratory outcome is change in participant reward and punishment responsiveness. Analysis will follow a prespecified statistical analysis plan. A nested qualitative study is included to examine feasibility and acceptability of the trial design.
A Clinical Trial Authorisation from Medicines and Healthcare products Regulatory Agency, and approval from the Health Research Authority (IRAS 1007468) and North East – Newcastle and North Tyneside 1 Research Ethics Committee (23/NE/0132) were obtained. Results will be disseminated through peer-reviewed publications, conference presentations and lay summaries for participants and patient and public groups.
Accurate assessment of insulin resistance, sensitivity and β-cell function is essential for early detection and management of metabolic disorders. However, reference intervals (RIs) commonly used in Nepal have been adapted from Western populations, which may not accurately reflect local physiological characteristics. Thus, this study aimed to establish population-specific RIs for fasting insulin and key insulin-related indices using a direct priori method in healthy adults from Gandaki Province, Nepal.
This cross-sectional study recruited 135 healthy adults (20–69 years, body mass index 18.5–24.9 kg/m²) representing different districts of Gandaki Province, Nepal. Fasting blood samples were analysed for glucose, insulin and lipids using standardised assays. Insulin was measured using the chemiluminescence immunoassay method. Nineteen different insulin-derived indices (Homeostasis Model Assessment 1 of Insulin Resistance (HOMA1-IR), Homeostasis Model Assessment 2 of Insulin Resistance (HOMA2-IR), Homeostasis Model Assessment for Triglycerides, Fasting Insulin to Glucose Ratio, Fasting Insulin Resistance Index, Metabolic Score for Insulin Resistance (METS-IR), InsuTAG, HOMA1-%S, HOMA2-%S, Quantitative Insulin Sensitivity Check Index (QUICKI), McAuley, Bennett, Raynaud, Glucose-to-Insulin Ratio, Fasting Insulin Sensitivity Index, Single Point Insulin Sensitivity Estimator (SPISE), reciprocal insulin, HOMA1-%B and HOMA2-%B) were calculated. Non-parametric 95% double-sided RIs (2.5th–97.5th percentiles) were established following outlier removal per Clinical and Laboratory Standards Institute-International Federation of Clinical Chemistry and Laboratory Medicine EP28-A3c guidelines.
The RI for fasting insulin was 2.63–14.56 µIU/mL (median 7.69 µIU/mL). Among the 19 mathematically correlated insulin-derived indices which are calculated from core measurements (fasting serum insulin and glucose), consistent patterns emerged across functional categories. Insulin resistance indices (HOMA1-IR: 0.56–3.50; HOMA2-IR: 0.30–1.70; METS-IR: 25.14–38.94) exhibited concordant right-skewed distributions with elevated upper limits. Conversely, insulin sensitivity indices (QUICKI: 0.32–0.42; HOMA2-%S: 58.83–233.20; SPISE: 5.75–10.86) demonstrated inverse, left-skewed patterns. Beta-cell function indices (HOMA1-%B: 0.54–322.21; HOMA2-%β: 40.74–159.52) also exhibited right skewed characteristics and revealed wide interindividual variability, reflecting preserved pancreatic reserve despite varying insulin resistance. Composite indices incorporating lipid parameters showed broader ranges, capturing additional metabolic heterogeneity.
This is the first study to define the RIs of fasting insulin and a spectrum of insulin derived indices in a Nepalese population. These findings offer a valuable framework for early detection and management of metabolic disorders in South Asian populations.
Climate change has led to extreme heat events, disproportionately affecting vulnerable populations. Heat stress during pregnancy is linked to adverse health outcomes, yet the biological mechanisms remain poorly understood. This research study aims to investigate the effect of environmental heat on maternal, fetal and infant health and examine the biological pathways linking heat stress to adverse pregnancy outcomes.
This prospective cohort study will recruit 6000 pregnant women from three districts in Sindh, Pakistan. Eligible participants ≥18 years old, will have a minimum of five scheduled visits from
The study has received ethical approval from the Aga Khan University (AKU) (Ref: 26249) and the Pakistan National Bioethics Committee (Ref: 1065/23/1736). Written informed consent will be obtained from all participants before enrolment. Referral pathways to healthcare facilities will be established to ensure timely management of pregnancy complications. Findings will be disseminated through peer-reviewed publications, scientific conferences, and engagement with policymakers and public health stakeholders to inform climate-resilient maternal health strategies. Results will also be shared with participants and communities through meetings and informal sessions to raise awareness and support evidence-based heat adaptation.
