Healthcare utilisation (HU) is key to improving the health of residents in urban informal settlements. This study aimed to explore household-level factors influencing HU among informal settlement households in Freetown, Sierra Leone.

Cross-sectional survey.

Three informal settlements (Cockle Bay, Dwarzark and Moyiba) in Freetown, Sierra Leone.

Primary data from 4871 households were collected during the Health and Wellbeing survey conducted between April and May 2023, targeting households with adults aged 18 years and older.

The primary outcomes were households HU both within and outside informal settlements. Household-level predisposing and enabling explanatory variables were derived from Andersen’s Behavioural Model of HU.

Disability in households increases HU within settlements (especially in Dwarzark, 13% and Moyiba, 10%) but is less likely outside. Households engaged in income-generating activities are more likely to seek healthcare within settlements, but 12% less likely outside in Cockle Bay and Dwarzark. Food insecurity decreases HU within Dwarzark (9%) and increases HU outside by 174% in Moyiba. Longer water fetching times and water shortages were associated with higher HU (between 6% and 16%) within settlements, especially in Cockle Bay and Dwarzark. Clean water sources (eg, piped dwelling, bowser, surface, bottled) were consistently associated with higher HU both within and outside settlements. Shared sanitation facilities (such as shared toilets) were positively associated with HU both within and outside settlements, particularly in Dwarzark and Moyiba. Households with income from fishing, informal salaried work and bike riding showed higher HU both within and outside settlements, especially in Dwarzark and Moyiba.

We identified strong settlement-specific patterns of household-level factors that influence HU both within and outside Freetown’s informal settlements. These findings provide a foundation for developing targeted policies such as strengthening local services, addressing affordability and accessibility barriers and supporting vulnerable occupation groups.

The impact of poor nutritional health on maternal and infant morbidity and mortality remains high in low- and middle-income countries (LMICs), exacerbated by climate change-linked disasters. Maternal nutritional health, as a modifiable factor, is influenced by various social, political, economic and environmental factors, as well as cultural practices. Identifying climate change-related interventions, adaptive strategies and best practices targeting maternal nutritional health and well-being in LMICs within a cultural context helps inform the co-production of sustainable, culturally sensitive interventions to improve health outcomes for mothers and babies.

We will undertake a systematic review of the literature employing the six steps of the Protocol, Search, Appraisal, Synthesis, Analysis and Report (PSALSAR) framework, including both peer-reviewed and grey literature. The Population, Concept and Context approach will be used to formulate the review question and the inclusion and exclusion criteria. We will include primary research comprising all study designs published in English from 2007 onwards. We will conduct searches in online academic databases, including CINAHL, MEDLINE, Global Health (CABI), AGRIS (FAO) and SCOPUS, as well as defined grey literature sources (ie, Google Scholar). Titles, abstracts and later full-text articles will be independently accessed and screened for eligibility criteria by four researchers. Following the integrative review methodology, we will present findings narratively, organised around the components of the PSALSAR framework to provide a comprehensive synthesis of the available evidence.

As no primary data will be collected, the systematic review does not require formal ethics approval. However, we will give attention to ethical considerations within the identified studies. Findings will be published in a peer-reviewed journal and presented at relevant conferences. The findings of our systematic review and the ethnographic component of our research project will inform the development of appropriate maternal nutritional health interventions using co-production methodology in Pakistan.

To evaluate the diagnostic accuracy of CT in identifying small and large bowel obstruction and associated complications, including ischaemia and perforation, in adult patients.

Systematic review and meta-analysis reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses of Diagnostic Test Accuracy reporting guidelines.

Ovid MEDLINE and Embase were searched from 1946 to 20 February 2025.

The study included randomised controlled trials, cohort studies and case–control studies evaluating the diagnostic accuracy of CT for bowel obstruction in adults (aged ≥18 years). Only studies published in English were included. Conversely, case reports, editorials, conference abstracts without full data and studies focusing exclusively on paediatric populations or animal models were excluded.

Three reviewers independently extracted data on study characteristics, CT modality, diagnostic accuracy metrics (sensitivity, specificity and predictive values) and complications. Risk of bias was assessed using the QUADAS-2 tool. A random-effects meta-analysis was conducted. Heterogeneity was assessed using I² and Tau² statistics.

Sixty-five studies with 9418 patients were included. The pooled sensitivity and specificity of CT for bowel obstruction were 90% (95% CI 78 to 96; I²=56%, Tau²=0.36) and 88.8% (95% CI 78.0 to 94.8; I²=65%, Tau²=0.35), respectively. For bowel ischaemia, CT showed a pooled sensitivity of 47.0% (95% CI 32.4 to 59.9; I²=0%, Tau²=0.00) and specificity of 85.3% (95% CI 77.9 to 89.5; I²=1%, Tau²=0.45). Multidetector CT (MDCT) outperformed older modalities across all endpoints. Ischaemia was present in 22.05% of all cases, with higher rates in small bowel obstruction. Perforation and mortality rates were 3.98% and 4.40%, respectively. No significant publication bias was detected, and the certainty of evidence was graded as moderate for most diagnostic accuracy outcomes.

CT, particularly MDCT, offers high diagnostic accuracy for bowel obstruction and is a critical tool for detecting serious complications such as ischaemia and perforation. However, sensitivity for ischaemia remains modest. Standardised protocols and prospective studies are needed to enhance early identification and optimise care pathways.

South Asia carries the burden of a rapidly changing climate with floods and extreme heat. These disasters further translate into mental health distress, financial stress and detrimental effects on well-being, with women being the most vulnerable. This study aims to demonstrate that mental health screening, referral and resilience-building group sessions can be successfully administered by community health workers and primary health facility staff in a flood-affected rural population of women in Pakistan and provide evidence on the effectiveness of this approach for improving their mental health status.

A quasi-experimental design with a comparison group will be used for the study, preceded by a formative phase. The formative phase evaluated the feasibility of mental health screening by Lady Health Workers (LHWs) in flood-affected areas using a qualitative approach such as focus group discussions and in-depth interviews. Manuals developed by the study team of mPareshan will be used to train LHWs, Lady Health Supervisors (LHS) and health facility staff. Following this, LHWs will briefly screen women aged 18 to 49 years, administer awareness-raising and resilience-building sessions and refer women who screen positive for depression or anxiety to a primary health facility. Physicians at the health facility will confirm the diagnosis and provide counselling to mild-moderate cases, while severe cases would be referred to specialists. Statistical evaluation of quantitative data and thematic content analysis of qualitative data will be conducted to assess the feasibility and impact of the intervention. This trial is registered at clinicaltrials.gov with number NCT06756165.

The study acquired ethical approval from the Ethical Review Committee at Aga Khan University (2024-10475-30776) and the National Bioethics Committee (4-87/NBC-1158/23/481) in Islamabad. Approval was obtained from relevant provincial authorities. The trial will adhere to the ethical principles of autonomy, anonymity, confidentiality, equity and respect. All eligible participants will be provided with informed consent, details regarding the purpose and procedure of the study, and the right to withdraw at any time. Data and information will be anonymised and stored securely. Dissemination of the results of the trial will occur after its completion to stakeholders, participants and the public.

The improved survival rates of children with cancer have heightened concerns about treatment-related chronic health conditions, including platinum-induced hearing loss (PIHL). Cisplatin and carboplatin, widely used in paediatric cancer therapies, frequently cause irreversible sensorineural hearing loss. PIHL affects 1.7–90.1% of patients exposed to these drugs, yet known risk factors—including age, cisplatin dosage, cranial radiation and co-treatment with ototoxic drugs—fail to fully explain interindividual variability. Genetic factors likely play a role in susceptibility to PIHL. Since genetic susceptibility in children may differ from adults, and given the critical window of auditory development, a focused investigation of paediatric genetic factors using quantitative methods is warranted to detect small to moderate effects and understand the polygenic nature of PIHL.

In this study, we will systematically review and conduct a meta-analysis of genetic polymorphisms associated with PIHL in individuals diagnosed before the age of 21 years. Following Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines, the review will include randomised controlled trials, cohort, case-control and cross-sectional studies that analyse the genetic influence on PIHL in paediatric populations treated with cisplatin and carboplatin. A comprehensive search of PubMed, EMBASE and Cochrane databases will be conducted, supplemented by backward citation searching. Data will be extracted on study design, treatment details, hearing loss assessment methods, genetic findings and covariates. We will use forest plots to present the results, and both Mantel-Haenszel fixed-effects model and random-effects model will be used for meta-analysis. Heterogeneity will be assessed with the I² index. The study will address potential heterogeneity, individual study quality, proportion of missing data and meta-analysis bias. The quality of the evidence of the meta-analysis will be assessed using the Grading quality of evidence and strength of Recommendations (GRADE) approach.

This systematic review will enhance our understanding of the genetic contribution to PIHL in children and serve as a basis for further research for improvement of personalised treatment strategies for paediatric cancer care.

All the included patient’s data are already published with an ethics approval for each study, respectively. No original data will be collected.

In critical care, intensive care unit (ICU) staff and physicians often estimate patients' height and weight visually, impacting calculations for cardiac function, ventilation, medication, nutrition and renal function. However, accurate assessment is challenging in critically ill patients. This study evaluates the accuracy of visual estimations by ICU staff.

Descriptive cross-sectional study.

National Institute of Cardiovascular Diseases, Karachi, Pakistan.

We included a convenient sample of adult (≥18 years) cardiac patients admitted to the critical care unit in this study. Patients who refused to give consent, trauma/surgery of lower limbs or patients with below-knee or above-knee amputation were excluded to avoid bias.

A convenient sample of cardiac ICU patients was included. Measured weight (kg) and height (cm) were compared with visual estimations by senior ICU nurse, senior non-ICU nurse, ICU consultants, fellows and residents. Correlation and agreement were analysed using Bland–Altman plots and 95% agreement limits.

A total of 356 patients were evaluated, of whom 204 (57.3%) were male, with a mean age of 55.2 ± 14.3 years. The median SOFA score was 3 [2–5], and 101 patients (28.4%) were on mechanical ventilation. The mean difference between measured and estimated weight by senior non-ICU nurse was 4.7±9.2 [–13.38–22.83] kg, senior ICU nurse was 7.8±9.9 [–11.56–27.12] kg, ICU consultants was 3.0±6.6 [–9.89–15.79] kg, ICU fellow was 3.0±7.1 [–10.88–16.92] kg and ICU resident was 8.0±9.6 [–10.83–26.79] kg. Similarly, the mean difference between measured and estimated height by senior non-ICU nurse was 2.0±7.3 [-12.36–16.34] cm, senior ICU nurse was 2.4±7.5 [–12.19–17.00] cm, ICU consultants was 1.5±5.6 [–9.51–12.48] cm, ICU fellow was 1.1±5.5 [–9.68–11.95] cm and ICU resident was 2.3±8.5 [–14.40–19.01] cm.

The findings indicate that healthcare professionals tend to overestimate both weight and height. The accuracy of these estimations varied among professional groups, underscoring the potential clinical consequences of such errors. This emphasises the need for objective measurements in clinical decision-making.
