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.
To develop and user-test a patient decision aid for people diagnosed with degenerative cervical myelopathy and who are considering surgery.
Mixed-methods study describing the development of a patient decision aid.
A draft decision aid was developed by a multidisciplinary steering group (including study authors with degenerative cervical myelopathy, health professionals and researchers) informed by the best available evidence, authorship consensus and existing patient decision aids.
Patient-participants and health professional-participants who manage people with degenerative cervical myelopathy were recruited through social media and the steering group’s research and practice network. Quantitative questionnaires were used to gather baseline data, descriptive feedback, refine the decision aid and assess its acceptability. Qualitative semi-structured interviews were conducted online to gather feedback on the decision aid and were analysed using reflexive thematic analysis.
We conducted 32 interviews: 19 patient-participants and 13 health professional-participants who manage people with degenerative cervical myelopathy (neurosurgeons, neurologists, physiotherapists, orthopaedic surgeons, general practitioners, rehabilitation and pain specialists and consultant occupational physicians and chiropractors). Participants were from 10 countries (Australia, Canada, Cyprus, Germany, Ireland, New Zealand, Sweden, Switzerland, United Kingdom and USA). Most participants rated the decision aid’s acceptability as good-to-excellent and agreed with most aspects of the decision aid (eg, defining degenerative cervical myelopathy, management recommendations, potential benefits and harms, questions to consider asking a health professional).
Our patient decision aid was rated as an acceptable tool by both health professional-participants who treat degenerative cervical myelopathy and patient-participants with lived experience of degenerative cervical myelopathy. This decision aid can be used by clinicians and people with degenerative cervical myelopathy to help with shared decision making following a diagnosis of degenerative cervical myelopathy. A study testing the potential benefits of this decision aid in a clinical setting is recommended.
Language-concordant care, or healthcare in one’s preferred language, is important both for health equity and for improving health outcomes. Linguistic minorities, like Francophones in Ontario, Canada, are at risk of poorer clinical outcomes if they receive non-language-concordant primary care. However, common ratio-based access measures can provide misleading views of minorities’ actual access levels. This cross-sectional geospatial study demonstrates a new way to measure primary care access using average travel time to the nearest five English- and French-speaking family physicians. We also introduce the concept of primary care access fragility, where a region’s primary care access may depend on one or a few local family physicians. Our research question is: are there differences in travel burden and access fragility for census subdivisions (CSDs) across language (English/French), rurality (urban/rural) and region (north/south) in the province of Ontario, Canada?
We conducted a cross-sectional geospatial analysis to estimate English-language and French-language primary care travel burdens and access fragility in Ontario, Canada. We used population and boundary data from Statistics Canada’s 2021 census, road-network data from OpenStreetMaps, and family physician practice locations and language abilities from the College of Physicians and Surgeons of Ontario. We measured travel burden using Valhalla, an open-source road-network analysis platform.
We conducted our analysis for Ontario, Canada’s 577 CSDs, which correspond roughly to municipalities and with populations ranging from 5 inhabitants in Rainy Lake 17B to a high of 2 794 356 in Toronto.
Using public data from January 2026, we identified 15 762 family physicians practising in Ontario, of whom 11.0% reported speaking French. Patient data were obtained from the most recent 2021 census.
Our first primary outcome measures were CSD-level mean travel time to the nearest five English-speaking family physicians, and CSD-level mean travel time to the nearest five French-speaking family physicians, which we compared to explore regional inequities in travel burden. Our secondary outcome measures were based on a novel notion of the travel burden component of ‘primary care access fragility’. This metric indicates how dependent a region’s access is on a small number of local physicians and is defined as the difference between the CSD-level mean travel time to the nearest one physician and to the nearest five physicians. As the difference in travel times grows, so too does access fragility.
Median differences in French-language and English-language travel burdens were strongly significant across rurality, regions and overall (median difference 13.4 min, p
Compared with the general public, Ontario’s French-speakers face higher travel burdens to language-concordant family physicians and higher access fragility, especially in rural and northern regions. Our results are of interest to policymakers and health-system planners, and our methods are applicable to other populations and regions.
To develop and evaluate an explainable machine learning framework enhanced with synthetic data generation to predict unplanned 30-day hospital readmissions among patients with chronic obstructive pulmonary disease (COPD), heart failure (HF) and type 2 diabetes mellitus (T2DM), and to identify key clinical and social predictors of readmission.
A retrospective cohort study using electronic health record data incorporating both structured variables and information extracted from unstructured clinical notes. Synthetic data were generated using advanced resampling and deep learning-based techniques to address outcome imbalance and improve model training.
Intensive care unit and general ward admissions at a single tertiary academic medical centre included in the MIMIC-IV (Medical Information Mart for Intensive Care IV) database.
Adult patients (≥18 years) were admitted with a primary diagnosis of COPD (n=14 050), HF (n=7097) or T2DM (n=12 735) between 2008 and 2019, with complete 30-day follow-up and no in-hospital mortality during the index admission.
The primary outcome was unplanned all-cause hospital readmission within 30-days of discharge. Predictors were drawn from six domains, including demographics, comorbidities, clinical acuity, therapies, behavioural factors and care continuity. Predictive performance was evaluated using multiple machine learning methods and fivefold cross-validation, with model interpretability assessed using established goal and local explanation approaches.
Ensemble-based machine learning models demonstrated the strongest predictive performance across all three disease cohorts. Key predictors of readmission included higher illness severity, greater comorbidity burden, medication non-adherence, gaps in preventive care and limited social support. Models incorporating synthetic data augmentation showed improved discrimination compared with models trained on original data alone.
An explainable synthetic-data driven framework incorporating clinical, behavioural and social data can support prediction of 30-day readmissions among patients with common chronic conditions using routinely available electronic health record data.
Spirituality is a crucial yet complex element of holistic nursing care, particularly when providing care for older adults with depression. In Thailand, depression poses a significant mental health challenge. Thai cultural values are deeply interwoven with individuals' beliefs, making spirituality a critical factor in addressing the care of older adults with depression. This study aimed to explore how older adults with depression experience spirituality and construct meaning from it in their daily lives.
An interpretative phenomenological study.
In-depth interviews of 30 older Thai adults living with depression (aged 60–85 years) from an outpatient psychiatric clinic in southern Thailand were conducted using semi-structured interview questionnaires. Interpretive phenomenological analysis was employed. Data were collected from June to August 2024.
Five themes emerged from the phenomenological data analysis: (1) elusiveness of spiritual meaning, (2) holding oneself together through inner power, (3) finding acceptance through faith in a higher power, (4) family ties shaping peace and despair, and (5) being guided and cared for.
This study highlights that older adults with depression perceive spirituality as essential for their well-being. Personal practices, such as meditation and chanting, played a key role in strengthening spirituality and reducing the risk of relapse in depressive symptoms, which are distinct for each older adult. Understanding spirituality's role in mental health guides nurses to develop strategies for providing more empathetic spiritual care.
Nurses must address depression in older adults through individualized practices to effectively empower their inner strength and coping mechanisms. Understanding each individual's spiritual practices is essential to help them harness their inner strength when coping with depression.
Sub-Saharan Africa (SSA) continues to be the hub of the global HIV/AIDS pandemic, globally. Despite several attempts to meet their HIV prevention needs, men continue to have high rates of HIV infection. Pre-exposure prophylaxis (PrEP) is an effective treatment that, when taken as prescribed, can be very efficient in preventing and reducing the risk of HIV acquisition. HIV self-testing (HIVST) has been demonstrated to be acceptable among men in SSA. As such, this review aims to explore the existing literature on the integration of PrEP dispensing with HIVST among men in SSA.
We will systematically search bibliometric databases, including PubMed/MEDLINE, Embase, Scopus, the Cumulative Index to Nursing and Allied Health Literature Plus, Sociological Abstracts, ProQuest Dissertations and Theses global. Our review will be guided by the Arskey and O’Malley framework and Levac et al. The review results will be reported using the preferred reporting items for systematic reviews and meta-analysis: extension for scoping reviews guidelines. To assess the methodological quality of the included articles, the mixed methods appraisal tool version 2018 will be used. We will use NVivo software (V.11) to synthesise data from the included studies using a thematic approach.
Ethical approval is not required, as this review uses publicly available data. Findings will be disseminated through peer-reviewed publication, conference presentations and engagement with key stakeholders in HIV prevention and treatment across SSA.

BackgroundToxoplasma gondii (T. gondii) is a successful protozoan parasite infecting up to a third of the human population. It has varied transmission routes including ingestion of food and water contaminated by cat feces containing oocysts of the parasite and ingestion of bradyzoites in poorly cooked meat. Blood transfusion is another possible route of transmission especially among people with medical conditions requiring blood transfusion, such as those with sickle cell disease (SCD). This study aimed at finding out the prevalence of T. gondii infection and the association of blood transfusion among patients with SCD.
MethodThis study was a cross-sectional study involving SCD patients attending the SCD clinic at the Ho Teaching Hospital in the Volta Region of Ghana. Questionnaire administration was employed to obtain sociodemographic information, cat ownership, consumption of poorly cooked meat, as well as blood transfusion history. A blood sample was collected and anti-T. gondii IgG and IgM were detected using Rapid Diagnostic Test (RDT), while Enzyme-linked Immunosorbent Assay (ELISA) was used as the gold standard and reference. Seropositivity was defined as either positive for IgG, IgM or both. Data was analyzed using SPSS version 23, with frequency distribution done for the sociodemographic variables and the prevalence of RDT and ELISA anti-T. gondii IgG and IgM. Pearson Chi-square analysis was performed to find any significant association between diagnosis of T. gondii infection with sociodemographic variables and blood transfusion. Logistic regression analysis was performed to investigate the odds of seropositivity (ELISA) with sociodemographic variables and blood transfusion.
ResultsA total of 156 SCD patients participated in this study of which 124 (79.5%) and 32(20.5%) were HbSS and HbSC respectively. Among the study participants, 105 (67.3%) had a history of blood transfusion. A total of 60 (38.5%) and 83 (53.2%) patients were positive for RDT and ELISA respectively. No significant association was seen between T. gondii diagnosis and cat ownership (RDT,20[37.7%], p = 0.891; ELISA, 27[50.9%], p = 0.673) and consumption of poorly cooked meat (RDT,37[41.6%],p = 0.370;ELISA,53[59.6%], p = 0.211). However there was a significant association between T. gondii diagnosis and age, with seropositive results predominantly seen among older patients (≥20 years) (RDT, 38[52.1%], p = 0.002; ELISA 49 [67.1%, p = 0.002]. Blood transfusion had a significant association with T.gondii diagnosis (RDT, p = 0.003; ELISA, p = 0.001). A total of 66 (62.9%) of SCD patients who had history of blood transfusion tested positive for ELISA and they had 3 times the odds of testing positive for ELISA (adjusted OR 3.14[95% CI 1.50–6.58]; p = 0.002).
ConclusionThe prevalence of T. gondii infection was higher by ELISA (53.0%) than by rapid diagnostic testing (RDT) (38.5%), and sickle cell disease patients with a transfusion history had higher odds of seropositivity. These findings highlight the need to strengthen transfusion safety protocols and consider screening strategies for T. gondii among high-risk populations such as patients with sickle cell disease. Also, there is the need for longitudinal research to help elucidate the true contribution of blood transfusion transmission of T. gondii since a cross-sectional study, causality could not be established.

Cornsilk flies, Euxesta eluta and Chaetopsis massyla (Diptera: Ulidiidae), are serious economic pests affecting sweet corn production in Florida. As a basis for development of enhanced trapping strategies, the sensory and behavioral basis for response to color was examined. Using electroretinograms, spectral sensitivity curves for both species revealed broad curves with a peak in the UV (350 nm) and the green region (500–550 nm) of the spectrum. Curves for males and females of each species were relatively similar in shape. Using pigment templates, the measured curve for E. eluta was matched by pigment combinations with maximum sensitivity at 350, 430, 500 and 560 nm in a ratio of 25:21:25:29. Similarly, the curve for C. massyla was best matched by pigments with maximum sensitivity at 350, 430, 500 and 560 nm in a 28:18:27:27 ratio. Laboratory behavioral assays were conducted to evaluate if attraction occurred in response to the color or the brightness of a target. Attraction responses were evaluated in paired tests to blue, green and yellow cards paired with gray cards of matching brightness. Despite relatively similar visual pigments, the two species differed greatly in their behavioral attraction. Euxesta eluta was only attracted to yellow cards at low or high brightness levels, to mid-level bright blue cards and not attracted to green cards at any brightness level. In contrast, C. massyla was highly attracted to yellow and green cards compared to gray cards of the same brightness but avoided blue cards. These differences in response to color and brightness are important for interpretation of surveillance results as well as development visual traps targeted for these species.
This study aims to explore the history of prior abortions and the factors influencing them among young women seeking abortion services in Foshan, Guangdong, China.
This is a retrospective, cross-sectional study of young women seeking abortion care.
Gynaecological outpatient clinics at the Department of Gynaecology, Foshan Women and Children Hospital Affiliated to Guangdong Medical University, Foshan, Guangdong, China, between 2013 and 2023.
A total of 7361 young women aged 12–25 years seeking abortion services.
Data on abortion history, sociodemographic factors, contraceptive use and postabortion contraceptive choices were collected and analysed, with special emphasis on the incidence of repeat abortions and the factors associated with them.
Of the 7361 participants, 34.2% reported at least one previous abortion, underscoring a notable public health concern. The mean age of the participants was 22.30 years (SD=2.13). Women with a history of abortion were significantly older than those without (22.57 vs 22.08 years, p
This study underscores the need for targeted interventions to address the multifaceted factors leading to repeat abortions among young women in China. The results offer valuable insights for improving reproductive health outcomes in this vulnerable population and highlight the importance of expanding access to contraceptive education and services in China.
To synthesise the prevalence and patterns of dementia-relevant structural brain MRI abnormalities in adults with suspected or confirmed dementia in low- and middle-income countries (LMICs), and to summarise MRI protocols and the incremental diagnostic contribution of MRI beyond cognitive screening.
Systematic review and meta-analysis.
PubMed, EMBASE, Web of Science and PsycINFO (January 1990–27 January 2025), plus reference list screening and targeted manual searches.
Observational or diagnostic-accuracy studies from World Bank-defined LMICs including adults (≥50 years) with suspected or confirmed dementia who underwent brain MRI as part of diagnostic evaluation.
Two reviewers independently screened, extracted data and assessed risk of bias using ROBINS-I. Random-effects models pooled prevalence of dementia-relevant MRI abnormalities; diagnostic-accuracy outcomes were synthesised narratively due to heterogeneous reference standards and incomplete reporting.
39 LMIC studies were included; 23 studies (2513 participants) contributed to the meta-analysis. Dementia-relevant MRI abnormalities (defined as ≥1 clinically relevant structural abnormality per study definition) were present in 1248/2513 participants. The pooled prevalence of dementia-relevant MRI abnormalities was 58% (95% CI 43% to 72%), with substantial heterogeneity (I²=95%) and a wide prediction interval (8–96%), indicating marked between-study variability; this estimate should be interpreted as a descriptive summary of study-level proportions rather than a precise population parameter.
Brain MRI frequently demonstrates dementia-relevant pathology in LMIC clinical cohorts, usually with mixed neurodegenerative-vascular patterns. Structured visual ratings may add aetiologic specificity beyond cognitive screening, but pooled estimates should be interpreted as summaries of heterogeneous study-level findings rather than precise population parameters, given high heterogeneity and risk of bias.

Spirituality has gained increasing attention in healthcare, particularly in palliative care, as it supports meaning, purpose and connection during illness. While literature extensively explores patients’ spiritual needs, growing evidence highlights the importance of addressing the spiritual needs of caregivers and healthcare professionals. Caregivers and relatives often face emotional, ethical and practical challenges during prolonged care pathways, impacting their well-being. Limited training and tools can hinder spiritual care, contributing to distress and burnout among professionals and unmet needs for families. Addressing spirituality in neurodegenerative disease palliative care is essential for holistic, person-centred approaches that foster coping, hope and ethical decision-making. This scoping review aims to map evidence on spiritual needs and challenges of caregivers, relatives and healthcare staff in end-stage neurodegenerative disease care.
This review will follow the Joanna Briggs Institute framework (JBI) for scoping reviews. The search and reporting process will be guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews checklist. Inclusion criteria followed JBI’s population, concept and context framework with no date or geographical limits; only English and Italian sources ensured accurate interpretation. Searches will use university-access databases and grey literature to capture policy and non-peer-reviewed sources. Databases selected: PubMed, CINAHL, APA PsycINFO and Scopus for comprehensive, multidisciplinary coverage. This inclusive approach is aligned with the purpose of scoping reviews, which aim to map the breadth and depth of available literature. Researchers independently screened titles/abstracts in Rayyan software with blinding, resolved discrepancies collaboratively, piloted and refined extraction tables, and jointly synthesised themes through iterative meetings to ensure rigour and consensus. Findings will highlight existing knowledge, identify gaps and inform future research and practice.
Since secondary data will be analysed, no ethical approval is required. The results will be disseminated through publications subject to peer review. The protocol has been registered with the Open Science Framework https://doi.org/10.17605/OSF.IO/X9275
Subjective well-being, a measurement of quality of life, varies systematically across racialised groups. However, the use of inconsistent subjective well-being measures across academic disciplines results in conflicting subjective well-being findings for people racialised as Black or African American in the USA. The aim of this scoping review is to provide a comprehensive overview of how subjective well-being is measured for people racialised as Black or African American in the USA and to examine how subjective well-being reports differ between people racialised as Black and white in the nation.
This scoping review will use the Joanna Briggs Institute methodology and report findings according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews guidelines. A predefined search strategy was used on 17 April 2024 to search PubMed (includes MEDLINE), APA PsycINFO (ProQuest), Sociological Abstracts (ProQuest), EconLit (EBSCOhost) and Scopus for studies published in English. Articles will be included if they specify Black or African American population, subjective well-being, and include populations within the USA. Data will be extracted and presented quantitatively and qualitatively in tabular and/or figure form to describe the characteristics and conclusions of included studies, grouped by subjective well-being component and measure. Analysis will identify methodological inconsistencies and research gaps.
This study does not require review by our institution’s review board as primary data will not be collected in this study. The findings of this scoping review will be disseminated through peer-reviewed publications, conference presentations, and condensed summaries for key partners in the field.

Video-assisted thoracoscopic surgery (VATS) lobectomy is a commonly employed surgical technique for the management of operable early stage non-small cell lung cancer (NSCLC). This procedure, however, is dependent on the patient’s ability to tolerate surgery. In light of this, stereotactic ablative radiotherapy (SABR) has emerged as a viable alternative treatment strategy for patients who are inoperable or who refuse surgery. Considering the lack of randomised controlled trials and the increased risk of bias in observational cohort studies, this study protocol proposes an emulated target trial design to investigate the causal effect of SABR, in comparison to VATS, on overall survival in operable early stage NSCLC patients.
Data on NSCLC patients will be collected from routinely collected university hospital records linked with German cancer registry data. This study protocol was developed using the target trial methodology outlined by Hernan et al. The protocol establishes specific parameters for key trial components in order to mitigate bias in the analysis of observational data and to facilitate the calculation of causal estimands. The target trial design that would be emulated is a multicentre open-label two-parallel arm superiority randomised trial. Mediators and confounding variables were determined through the use of a directed acyclic graph. The statistical analysis aims to measure the per-protocol and intention to treat effect of SABR versus VATS within 3 months of diagnosis, on survival, through the difference in restricted mean survival times, using weighted non-parametric Kaplan-Meier curves.
The Ethics Committee of the Medical Faculty of Martin Luther University Halle-Wittenberg with an approved addendum with Dnr 2023–112 has approved this study. The study uses anonymised routinely collected hospital and cancer registry data in accordance with applicable data protection regulations. Results will be disseminated through peer-reviewed publications and presentations at scientific conferences.
Suicide is a major public health concern among youth in Canada and worldwide. The most rapid increases in suicidal ideation, self-harm, and suicide attempts have been observed among adolescent girls, particularly since the COVID-19 pandemic. Recent studies report disproportionately high rates of emergency department visits and hospitalisations for suicide-related concerns among adolescent girls. Despite these concerning trends, limited evidence exists on the life trajectories, needs, and service pathways of adolescent girls who attempt suicide. This protocol describes a qualitative suicide audit focused on adolescent girls aged 12–17 who were hospitalised following a suicide attempt in two regions of the province of Québec, Canada. The aim is to understand developmental trajectories, document services received and identify individual, relational and systemic factors influencing these trajectories to generate recommendations that inform suicide prevention.
Using a narrative qualitative design and a community-based research approach, data will be collected from semi-structured interviews with adolescents and parents, parent questionnaires and hospital health records. These data will be integrated to develop anonymised case vignettes. A multidisciplinary panel, including clinicians, health system stakeholders, community partners and individuals with lived experience, will review each case to identify gaps and strengths in care and generate case-level and cross-case recommendations for clinical practice, health policy and professional training.
Ethics approval was obtained from the research ethics committee (REC) of the Centre intégré de santé et de services sociaux de Chaudière-Appalaches, which serves as the reviewing REC, with administrative reviews underway at two other health authorities. Findings will be disseminated through peer-reviewed publications, conference presentations and collaborative knowledge-mobilisation activities with clinical and community partners, including practice-oriented tools and accessible materials for adolescents and parents.
Non-communicable diseases (NCDs) have become the leading cause of mortality globally, with a sharp rise in Iran due to lifestyle changes and urbanisation. Although many NCD risk factors are modifiable, limited understanding of their determinants hinders effective prevention. To address this, the Prospective Epidemiological Research Studies in Iran (PERSIAN) Cohort was established in 2014 to study NCDs nationwide. The Sabzevar PERSIAN Cohort Study (SPECS) is the first in northeastern Iran, aiming to investigate environmental and social factors influencing NCDs in a unique regional context.
SPECS enrolled 5174 adults (aged 35–70 years) in northeastern Iran between January 2018 and January 2019 through a census and an online registration process. The baseline data collection included demographic verification, informed consent, health questionnaires, anthropometric measurements and biological samples (blood, urine, hair, nails). The annual follow-up began in April 2019, with full reassessments every 5 years over a 15-year period. The data is gathered via an active and passive follow-up, supported by trained staff and registry linkages.
Of the 5174 participants, 4241 (81%) remained in the study. Among the cohort, 54.5% were female, with a mean age of 50.5 years. The majority were married (93.5%), and nearly half had at least high-school education (46.5%) and moderate socioeconomic status (49.4%). Drug abuse history (smoking/drugs) was reported by about 15% of the sample. The mean body mass index was 26.9 kg/m², and the average blood pressure was higher in males (118.1/74.0 mm Hg) than in females (111.5/70.2 mm Hg). The common conditions included hypertension (22.8%), kidney stones (22.4%), fatty liver (15.4%) and diabetes (13.8%). Cancer had the highest treatment rate (100%), while fatty liver had the lowest (70.1%). Stroke had the highest mean age of onset (51.2 years), and epilepsy the lowest (23.7 years). All health data were self-reported.
SPECS, part of the national PERSIAN cohort initiative, is the only adult NCD-focused study in Khorasan Razavi. Its 15-year follow-up aims to generate region-specific insights into the incidence of NCDs and their risk factors. The ethnically homogeneous sample enhances statistical power, and the findings may inform culturally tailored health policies. While self-reported data have limitations due to bias, high initial participation and access to free healthcare support long-term engagement, especially among lower-income groups.
Clinical documentation is a significant driver of burnout among physicians. Ambient artificial intelligence (AI) scribes, which leverage generative large language models to automate the creation of clinical notes from patient–physician conversations, are rapidly emerging as a potential solution. While these tools promise to enhance efficiency and reduce administrative tasks, concerns about the quality, accuracy and potential biases persist. There is now a need for a systematic synthesis of evidence to evaluate the impact of these technologies in clinical practice. To assess the effects of ambient AI scribes on physicians’ clinical documentation, the specific objectives are to: (1) evaluate the effectiveness of these tools on documentation, including accuracy and completeness; (2) synthesise evidence on the impact on physician efficiency after adoption, including time spent on documentation and (3) examine physicians’ satisfaction with these tools, including physicians’ perceived burden.
A systematic review of quantitative or mixed-method studies as well as preprints will be conducted. We will perform a comprehensive search of four electronic databases (PubMed, IEEE Xplore, APA PsycInfo and Web of Science, along with medRix and ClinicalTrials.gov for preprints) for empirical studies published between January 2023 and March 2026. The review will synthesise studies comparing physicians’ use of ambient AI scribes with traditional documentation approaches. Given the anticipated heterogeneity of the studies, a narrative synthesis will be employed to summarise the findings. Where common quantitative outcomes exist, effect sizes will be calculated using Hedges’ g, mean differences or risk ratios/odds ratios as appropriate. The overall quality of evidence will be assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) framework.
As no patient data are involved in the data collection, no ethical approval is acquired. Results will be disseminated in a peer-reviewed, open-access journal, and presented at relevant academic conferences.

Impaired cytoplasmic dynein function has been implicated in amyotrophic lateral sclerosis (ALS) pathogenesis, yet the contributions of spinal interneurons to disease phenotypes remain unclear. We tested the hypothesis that hypomorphic dynein function in cholinergic neurons disrupts the development, survival, or positioning of inhibitory interneuron populations in the lumbar spinal cord. Using ChAT-Cre recombination, we generated four mouse genotypes with graded reductions in dynein activity in ChAT+ cells: Dync1h1+/+ (wildtype), Dync1h1−/+ (hemizygous wildtype), Dync1h1+/Loa (heterozygous Loa mutation), and Dync1h1−/Loa (hemizygous Loa). At 52 weeks of age, lumbar spinal cords (L3–L6) were harvested, cryosectioned, and immunostained for ChAT, GAD-67, Parvalbumin, and Calbindin. Cell counts were performed on confocal images from eight sections per mouse (N = 3 male mice/genotype), and radial distances from the central canal were normalised to gray matter width. Angular distributions were analysed via circular statistics. There were no significant genotype-dependent differences in the numbers of ChAT+, GAD-67+, Parvalbumin+, or Calbindin+ cells, nor in ChAT+ subpopulations (motor neurons versus interneurons) or double‐positive interneuron subsets (e.g., ChAT+–GAD-67+, Parvalbumin+–GAD-67+, Parvalbumin+–Calbindin+). Radial positioning relative to the central canal was similarly preserved across all markers and genotypes. Circular‐median tests revealed statistically significant shifts in mean angle for ChAT+, GAD-67+, and certain double‐positive cells, but these amounted to only 5–10° displacements, translating to lateral shifts of ~10–20 µm, well within single laminar bands, and are unlikely to impact circuit connectivity. Despite substantial motor deficits and hallmark TDP-43 pathology previously seen in these models, impaired dynein function does not precipitate interneuron loss or gross migratory defects in the lumbar spinal cord. Instead, our findings suggest that the primary contributions of dynein to ALS-like phenotypes likely arise from functional disruptions in axonal transport, synaptic maintenance, and neuronal physiology rather than from structural alterations or loss of interneuron populations.

Multimorbidity, the presence of multiple chronic health conditions, is a leading cause of death globally. In Malawi, chronic noncommunicable and communicable diseases such as HIV frequently co-exist, putting pressure on an under-resourced system. However, the health system is primarily structured around disease-specific [vertical] programs, which hinders person-centred care approaches to multimorbidity. Our study focuses on multimorbidity care and explores the perceptions of healthcare workers on the patient pathways and service organisation throughout the patient’s interaction with the health facilities. This cross-sectional qualitative study took an interpretivist approach. We conducted 13 days of clinical observations at Queen Elizabeth Central Hospital and Chiradzulu District Hospital. We also conducted 13 days of clinical observations and semi-structured in-depth interviews with different cadres of purposively sampled healthcare workers (n = 22) at Queen Elizabeth Central Hospital and Chiradzulu District Hospital. Through thematic analysis, we identified an understanding of the organisation of care and healthcare workers’ perspectives on the delivery of services. Findings showed both hospitals provided services for inpatients and outpatients with multimorbidity, including screening, management, prevention of secondary conditions and rehabilitation. Patient diagnosis and management for multimorbidity were often delayed due to frequent stockouts of medication and consumables necessary for diagnostic testing for NCDs at the hospital level. Some healthcare workers were not equipped with the knowledge, skills, or guidelines to manage multimorbidity. As HIV care is currently better resourced than other chronic conditions, healthcare facilities may strengthen the supply chain, healthcare workers’ training sessions and monitoring and evaluation tools to ensure NCDs are well managed, learning from HIV programmes.
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.

Staphylococcus aureus bacteraemia (SAB) is a common and severe infection, with a 90-day mortality of 24%–32%. Cloxacillin is regarded as a first-line antibiotic treatment in SAB in Sweden. However, exposure to cloxacillin in real-world hospitalised patients with SAB, most of whom are elderly patients treated outside the intensive care unit, is not well described. There are also limited data on the role of unbound cloxacillin exposure in relation to renal function or drug-induced toxicity.
This multicentre, prospective, observational clinical trial will include 95 adult patients with methicillin-susceptible S. aureus bacteraemia, treated with cloxacillin. Patients with endocarditis, polymicrobial bacteraemia or those considered unsuitable for cloxacillin treatment are excluded. Trough and peak total and unbound cloxacillin concentrations will be measured at steady state at days 2 and 7. Blood cultures will be obtained at days 2, 3, 4 and 7 to assess time to negative culture. Renal function will be assessed daily for plasma creatinine and at days 1 and 6 for cystatin C and for 12-hour urine creatinine clearance. In a novel approach to detecting nephrotoxicity, renal tubular damage biomarkers will be measured at days 1 and 6 (KIM-1, N-acetyl-β-D-glucosaminidase, neutrophil gelatinase-associated lipocalin, urine cystatin C, alpha-1-microglobulin). Detection of neurologic symptoms such as confusion, tremor, hallucinations and convulsions, as well as consciousness, will be monitored daily using a structured evaluation form.
We aim to investigate to which extent target attainment (100% of the dosing interval during which the free (unbound) drug concentration exceeds the minimum inhibitory concentration) is achieved with standard dosing of cloxacillin in a real-world cohort of hospitalised patients with SAB, and whether initial renal function can predict who is at risk for underdosing or overdosing. We will also explore whether neurological or renal damage is prevalent and associated with cloxacillin levels.
