Limited data exist on temporal changes in antibiotic use in low and middle-income countries. We evaluated trends in antibiotic use at tertiary hospitals in Uganda.
Retrospective trend analysis of a repeated point prevalence survey (PPS).
This study utilised antibiotic use data from quarterly PPS conducted among inpatients at nine regional referral hospitals in Uganda between October 2020 and December 2023.
We determined the proportions of antibiotic use, prescriptions guided by culture and sensitivity tests (CST), WHO AWaRe (Access, Watch and Reserve) categories, and prescriptions without documented indication. Linear regression was used to derive slope coefficients and 95% confidence interval (CI).
Of 15,154 patients surveyed, 8,892 (58.7%) received systemic antibiotics. The median age was 23 years (IQR: 11–38), 5,338 (60.5%) were female, and 4,583 (51.5%) were on treatment for infectious syndromes, including sepsis (1,400, 15.7%) and pneumonia (867, 9.8%). The drug utilisation index (DU75) consisted of ceftriaxone, metronidazole, gentamicin and ampicillin, which accounted for 76.9% (12,291/15,989) of total antibiotic use. The distribution of prescribed antibiotics was 46.6% Access, 45.5% Watch, 0.1% Reserve and 7.7% unrecommended combinations. Overall, 5,402 (60.8%) prescriptions were aligned with national guidelines, 2,147 (24.1%) prescriptions were issued without an indication, and CST guided 271 (3%) prescriptions. Over time, there was no significant change in antibiotic prescription prevalence (slope=0.09, CI –0.93 to 1.10) and prescriptions without indication (slope=–0.70, CI –1.79 to 3.98). However, adherence to treatment guidelines (slope=2.06, CI 0.14 to 3.98) and prescriptions based on CST results (slope=0.62, CI 0.12 to 1.13) significantly increased, while ‘Watch’ antibiotics prescriptions decreased (slope=–0.40, CI –0.63 to –0.17).
The antibiotic prescription rate remained high, with no significant change over time. Improvements were seen in adherence to treatment guidelines, use of CST and reduced use of ‘Watch’ antibiotics. Strengthening antibiotic stewardship is recommended to further improve practices.

PurposeTo define optimal exposure parameters and the therapeutic window for transscleral photodynamic therapy (TSPDT) with chlorin e6 by evaluating clinical, histological, and thermal effects of subthreshold, therapeutic, and suprathreshold settings in rabbit eyes.
MethodsThe study was conducted on 21 healthy rabbits. TSPDT was performed using a 660 nm laser and chlorin e6 (2.5 mg/kg). Transscleral probes (5 mm: 0.1 W, 0.17 W, 0.3 W; 10 mm: 0.3 W, 0.6 W) with integrated thermosensors were used. Enucleation and histological analysis were performed 14 days post-irradiation.
ResultsFundus examination on day 14 revealed distinct treatment zones correlating with laser settings. The therapeutic window was defined as 0.14–0.17 W (5 mm probe; power density: 0.693–0.866 W/cm²; energy density: 415.8–519.6 J/cm²) and 0.48–0.6 W (10 mm probe; 0.611–0.764 W/cm²; 366.6–458.4 J/cm²) with 600 s exposure time, achieving selective choroidal damage without scleral or retinal injury (ΔT ≤ 4.5°C). Suprathreshold settings (≥0.3 W for 5 mm; ≥ 0.6 W for 10 mm) induced retinal necrosis (up to 50%) and scleral coagulation (ΔT ≥ 8°C) with power densities exceeding 0.866 W/cm² (5 mm) and 0.764 W/cm² (10 mm).
ConclusionTSPDT with chlorin e6 enables selective targeting of intraocular pathological tissues while preserving scleral and retinal integrity. Defining the therapeutic window and using real-time thermal monitoring enhances treatment safety. These findings lay a foundation for clinical protocols for uveal melanoma and other intraocular tumors.
Little is known about how young people use social media during periods of self-harm. This study aimed to explore how they express themselves online through images posted on social media before and after self-harm and how this expression may change across these periods, employing visual content and thematic analyses.
A prospective cohort study, with qualitative analysis conducted using a recurrent cross-sectional approach and codebook methodology, accounting for chronological changes across time points before, during and after episodes of self-harm.
Participants were recruited from a mental health NHS Trust in the UK.
Image data during episodes of self-harm was available for 20 participants. The majority of whom were aged 18 years or older (n=15), female (n=14) and met criteria for moderate or severe anxiety and depression (n=18). The sample reflected diverse ethnic backgrounds, with six participants identifying as Asian or Mixed/Multiple ethnic backgrounds.
None of the images investigated had direct visual presentations of self-harm. A few images referenced self-harm through the medium of text, and this was largely to normalise and promote help-seeking. Several themes were identified, including participation in activities that support well-being, love and relationships, connecting through humour, expressions of distress, and promoting mental health awareness and support. Subtle temporal changes were also observed.
Findings suggest that young people may temporarily withdraw from social media on the day of a self-harm event and rarely post graphic self-harm images around that time. This may reflect concerns about being stigmatised, but also improved platform moderation. Instead, platforms may serve as spaces for expressing self-care behaviours and connecting with others about both positive and challenging emotions, and across a range of topics including mental health.

To develop a method for computationally detecting fall events using clinical language models to complement existing self-reporting mechanisms.
Retrospective observational study.
Text data were collected from the unstructured nursing notes of three hospitals' electronic health records and the Korean national patient safety reports, totalling 34,480 records covering the period from January 2015 to December 2019. Note-level labelling was conducted by two researchers with 95% agreement. Preprocessing data anonymisation and English translation were followed by semantic validation. Five language models based on pretrained Bidirectional Encoder Representations from Transformers (BERT) and Generative Pretrained Transformer (GPT)-4 with prompt programming were explored. Model performance was assessed using F measurements. Error analysis was conducted for the GPT-4 results.
Fine-tuned BERT models with the English data set outperformed GPT-4, with Bio+Clinical BERT achieving the highest F1 score of 0.98. Fine-tuned Korean BERT with the Korean data set also reached an F1 score of 0.98, while GPT-4 achieved a competitive F1 score of 0.94. GPT-4 with prompt programming showed much higher F1 scores than GPT-4 with a standardised prompt for the English data set (0.85 vs. 0.39) and the Korean data set (0.94 vs. 0.03). The error analysis identified that the common misclassification patterns included fall history and homonyms, causing false positives and implicit expressions and missing contextual information, causing false negatives.
The clinical language model approach, if used alongside the existing self-reporting, promises to increase the chance of identifying the majority of factual falls without the need for additional chart reviews.
Inpatient falls are often underreported, with up to 91% of incidents missed in self-reports. Using language models, we identified a significant portion of these unreported falls, improving the accuracy of adverse event tracking while reducing the self-reporting burden on nurses.

Child undernutrition is linked to substantial national economic and health losses in low- and middle-income countries, including Rwanda. Although the causal and contextual factors contributing to chronic malnutrition in children in Rwanda have been explored, the role of the mothers’ mental health has not been fully investigated. This study aims to determine the prevalence of major depressive disorders, generalised anxiety and suicide risk among mothers in Rwanda and to explore their association with child stunting.
This study used a cross-sectional, population-based design.
Participants included children aged 1–36 months (n=601) and their mothers (n=601) in Rwanda’s Northern Province. Mothers’ mental health was assessed using four modules from the Mini International Neuropsychiatric Interview, based on the Diagnostic and Statistical Manual of Mental Disorders. Child anthropometric measurements followed WHO guidelines.
The primary outcome of the study was child stunting that was defined as a height-for-age Z (HAZ) score
Among the 601 mothers assessed, generalised anxiety disorder had the highest prevalence (36.6%), followed by recurrent major depressive disorder (27.3%), current major depressive disorder (22.7%) and current suicide risk (18.2%). Among the children, 27.1% were stunted, with prevalence rising from 9.8% in infants (1–12 months) to 39.9% in toddlers (25–36 months). Current major depressive disorders in mothers were associated with child stunting (adjusted OR 1.67; 95% CI 1.06 to 2.61). Affected children had lower HAZ scores (–1.68±1.36 vs –1.30±1.09; p=0.004), and excess relative risk (ERR) analysis confirmed depression as a significant risk factor (ERR: 1.56; p=0.005).
Mental health disorders in mothers, especially depression, showed a significant association with child stunting. Addressing mental health disorders in mothers is essential for improving child nutritional outcomes.
Informal caregivers play a vital role in caring for individuals who choose to spend the end of their life at home. However, this caregiving role often imposes considerable physical, emotional, social and financial burdens that can negatively impact caregivers’ quality of life. A comprehensive understanding of the breadth of interventions designed to support caregivers of individuals receiving home-based palliative and end-of-life care is essential, along with insights into how these interventions are perceived by those who have received them. The objective of this review is to synthesise existing evidence on the effectiveness and appropriateness of interventions that support informal caregivers of patients receiving home-based palliative care in order to address the caregivers’ needs and improve their quality of life. Additionally, this review aims to explore the acceptability and perceived benefits of these interventions from the perspectives of informal caregivers who have received them.
A comprehensive search will be performed in the following databases: MEDLINE (PubMed), CINAHL, PsycINFO, Web of Science, Scopus, Cairn.info, EMBASE and the Cochrane Central Register of Controlled Trials (CENTRAL). This review will include studies that focus on adult informal caregivers of adult patients with serious life-threatening illnesses receiving home-based palliative care. Interventional studies that employed quantitative, qualitative and mixed-methods approaches will be considered. Quantitative studies will include randomised controlled trials (RCTs) and experimental and quasi-experimental designs. Qualitative studies will encompass research that explores informal caregivers’ experiences with the interventions, perceived benefits and barriers and enablers influencing intervention effectiveness. Mixed-methods studies using convergent, embedded or sequential designs will also be included.
The search will include studies published in English or French, with no restrictions on the publication period. Study selection, critical appraisal and data extraction will be conducted independently by two reviewers to ensure methodological rigour. This review will adhere to the Joanna Briggs Institute guidelines for mixed-methods systematic reviews, using a convergent segregated approach. Findings will be reported in accordance with the Preferred Reporting Items for Systematic Review and Meta-Analyses guidelines.
Ethical review is not required for this study, as it is a literature review that does not involve the collection of primary data. The findings of this review will be disseminated to the scientific community through conference presentations and peer-reviewed publications. Additionally, lay summaries will be prepared and shared with the general public and relevant stakeholders.
