To assess how preoperative anaemia affects surgical outcomes in elderly patients within a resource-limited setting.

Prospective cohort study.

Two comprehensive specialised hospitals in Ethiopia.

Participants consisted of 224 patients aged 65 years and older who underwent surgery between 1 December 2024 and 29 March 2025.

Perioperative blood transfusions were the primary outcome. Secondary outcomes included intensive care unit (ICU) admission, risk of postoperative complications, prolonged hospitalisation, poor recovery quality and in-hospital mortality.

The anaemic group required transfusions of three or more units more frequently than the non-anaemic group (10.5% vs 2.6%; absolute risk difference 8.0%). Their perioperative transfusion rates were significantly higher (42.3% vs 18.4%; p

Preoperative anaemia significantly increases the risk of transfusion, poor recovery, ICU admission, prolonged hospitalisation and in-hospital mortality in older patients who underwent surgery. In resource-limited settings, improving perioperative outcomes should prioritise the early detection and treatment of anaemia.

Current pharmacological treatment options for painful diabetic neuropathy (PDN) often fail to provide adequate pain relief. However, in the recent SENZA-PDN study, high-frequency 10 kHz spinal cord stimulation (SCS) demonstrated significant long-term improvements in lower limb pain and health-related quality of life (HRQoL) in a PDN population. Furthermore, more than half of 10 kHz SCS recipients showed improved sensory function based on non-blinded clinical assessments in post hoc analysis. We report the design of the PDN-Sensory study, which aims to evaluate changes in pain and neurological function with 10 kHz SCS in the treatment of PDN. The study will include objective measures of neurological function, including the modified Toronto Clinical Neuropathy Score (mTCNS) and intraepidermal nerve fibre density (IENFD).

This multicentre, prospective, randomised controlled trial will compare conventional medical management (CMM) with 10 kHz SCS+CMM in individuals with diabetes and chronic, intractable lower limb pain due to PDN. Participants will be randomised 1:1 to CMM alone or 10 kHz SCS+CMM, with optional crossover at 6 months. The primary outcome is the proportion of participants at 6 months achieving ≥50% pain relief from baseline. The key secondary endpoint is the proportion of participants at 6 months with a reduction in mTCNS of ≥3 points from baseline (excluding changes in foot pain). Additional endpoints at 6 and 12 months include changes from baseline in mTCNS, IENFD, 7-day averaged pain score, pain-related interference, HRQoL, sleep, psychological outcomes, functional status and metabolic parameters.

The study protocol received central approval from the Western Institutional Review Board (IRB #20230954). Local IRB approval will be required before initiation of the study at each participating clinical site. The study complies with Good Clinical Practice guidelines (ISO 14155), the Declaration of Helsinki, and all applicable national, federal and local regulatory requirements. Dissemination plans include presentations at national and international conferences and publication in a peer-reviewed journal with open access.

To assess awareness of colorectal cancer (CRC) symptoms and risk factors among adults attending Sri Lanka’s largest tertiary care hospital, and to identify sociodemographic predictors of awareness.

Descriptive cross-sectional study.

Outpatient clinics at the National Hospital of Sri Lanka (NHSL), the country’s largest tertiary care centre.

A total of 506 adults (≥18 years) recruited via convenience sampling. Data were collected from May 2022 to May 2023 at the outpatient clinics of the NHSL, the country’s largest tertiary care centre. Eligible participants included clinic attendees as well as accompanying persons of attendees, provided they met inclusion criteria. Individuals with known gastrointestinal conditions or malignancies were excluded.

Primary outcomes: awareness scores of CRC symptoms and risk factors using a culturally adapted Bowel Cancer Awareness Measure questionnaire.

Secondary outcomes: predictors of awareness based on sociodemographic variables.

58.7% (n=297) of participants could not name any CRC symptoms unprompted; blood in stools (n=93, 18.4%) was the most identified symptom unprompted. Prompted awareness improved markedly, with 75.3% (n=381) identifying blood in stools when provided with a list. Similarly, 44.3% (n=224) could not identify any CRC risk factors unprompted; excessive alcohol intake (n=368, 72.7%) and low fibre intake (n=324, 64.0%) were the most commonly recognised risk factors when prompted. The mean symptom awareness score was 5.63 (SD=2.55), corresponding to ‘fair’ awareness, and the mean risk factor awareness score was 5.47 (SD=2.63), also indicating ‘fair’ awareness. Female gender (B=0.669, p=0.008; n=237) and older age (B=0.023, p=0.034) were significantly associated with higher symptom awareness. Awareness was significantly lower among participants with lower education (B = –0.104, p=0.018; n=219) and among the unemployed (B = –0.175, p=0.045; n=152).

Unprompted awareness of CRC symptoms and risk factors was suboptimal in this population, with marked gaps in spontaneous recall. Public health campaigns should prioritise men, younger adults and individuals with lower education to enhance CRC literacy and promote earlier detection.

Health systems must guarantee access to quality, safe and effective medicines. Essential medicine lists (EMLs) are crucial prioritisation tools to inform coverage decisions and steward limited health resources under the context of universal healthcare. This study aims to develop a consolidated framework for prioritising the assessment of health technologies to review and update EML for treating diseases or health problems managed in primary healthcare (PHC).

A mixed-methods approach was designed to validate the framework. An initial scoping systematic review will be conducted to search for studies that describe criteria used to prioritise the assessment of health technologies for PHC. The relevant studies will be examined using the Joanna Briggs Institute methodological framework for scoping review studies. A comprehensive search was conducted in the following sources: PubMed, Embase, Cochrane Library, Virtual Health Library (LILACS, WHO IRIS, IBECS, PAHO-IRIS, PAHO, LIS, BRISA), Health System Evidence, Global Healths, Health Evidence and Epistemonikos from the inception until February 2025. Two review authors will screen and extract data independently. The extracted data will be qualitatively analysed and presented in a diagrammatic or tabular form, alongside a narrative summary, in line with Preferred Reporting Items for Systematic Reviews and Meta-Analysis: Extension for Scoping Reviews reporting guidelines. An iterative process online using the Delphi hybrid with stakeholders through predetermined consensus thresholds, a combination of a four-point Likert scale and open-ended questions will be conducted to select and validate the criteria identified in the scoping review.

We will provide a consolidated framework to inform decision-makers for prioritising the assessment of health technologies for the national EML for PHC. This is an important step in using evidence to inform public health policies. We plan to share findings through a variety of means, including publications in peer-reviewed journals, presentations at national conferences, invited workshops and webinars, email discussion lists affiliated with our institutions and professional associations, and academic social media.

Assess the magnitude of adverse pregnancy outcomes and associated factors among mothers who had operative vaginal delivery in Amhara Region Comprehensive Specialized Hospitals, 2024.

A cross-sectional study was conducted from 1 November 2024 to 20 February 2025.

Seven comprehensive specialised hospitals were included in the study.

The study was employed on 389 mothers who had operative vaginal delivery.

Systematic sampling was used. Data were collected via questionnaires, chart reviews and observation. Data were entered into Epi Data V.4.6 and analysed using V.25 statistical package of social sciences. Variables with p

Adverse pregnancy outcomes of operative vaginal delivery.

Adverse pregnancy outcomes of operative vaginal delivery were 42.2%. Among them, 46 (11.8%) had only maternal complications, 55 (14.1%) had only neonatal complications and 63 (16.2%) had both maternal and neonatal complications. Perineal tear 29 (7.5%) and episiotomy extension 31 (8%) were the most common maternal complications, while caput succedaneum 45 (11.6%) was the most neonatal complication. The most common indication of operative vaginal delivery was prolonged second stage 203 (52.2%). Vacuum-assisted delivery (AOR 0.53; 95% CI 0.29 to 0.96), two tractions (AOR 2.19; 95% CI 1.23 to 3.90), birth weight less than 2.5 kg (AOR 1.85; 95% CI 1.21 to 2.83) and mid fetal station (AOR 2.9; 95% CI 1.49 to 5.64) were significantly associated with adverse pregnancy outcomes.

Adverse pregnancy outcomes following operative vaginal delivery were high. Type of instrumental vaginal delivery, number of tractions, fetal birth weight and fetal station were significantly increased risks. Therefore, operators should minimise traction attempts during operative vaginal delivery to reduce adverse outcomes.

Length-for-age z-scores (LAZ) and stunting prevalence (%LAZ

We simulated a synthetic cohort with a harmonically downward-shifting LAZ trajectory from birth to 24 months of age, with mean LAZs similar to the HBGDki pooled South Asian cohorts, and without any input parameters intended to differentially affect individuals’ growth across the height distribution or at different ages. We compared HBGDki empirical estimates of age interval-specific frequencies of incident stunting onset and stunting reversal with those from the synthetic cohort. Using synthetic cohorts, we examined how estimates of incident onset and reversal were affected by missing data, magnitude of the whole-population shift in the LAZ distribution and strength of the between-time-point correlation. We also compared the 3–24 month pattern of linear growth faltering expressed as age-related trajectories of average growth delay (chronological age minus height–age), mean LAZ or stunting prevalence.

Empirical estimates of age interval-specific incident stunting onset and stunting reversal in the HBGDki cohorts were similar to those observed in a synthetic cohort. Variability in LAZ threshold-crossing event rates is explained by starting LAZ, between-time-point correlation and the magnitude of the whole-population shift in the LAZ distribution. Incident stunting onset is also affected by missing data in preceding intervals. Stunting reversal occurs due to within-child variability (ie, imperfect between-time-point correlation) in the absence of any other phenomena that cause stunted children to become non-stunted at a later age. The linear growth faltering pattern based on growth delay differed from corresponding age-related trajectories of mean LAZ or stunting prevalence.

In longitudinal studies of linear growth faltering in LMICs, LAZ threshold-crossing indicators are byproducts of whole-population shifts in LAZ and within-child variability and should be interpreted accordingly. Reporting incident stunting onset and reversal rates, or analyses in which children are grouped by the timing of LAZ threshold-crossing events, may detract from efforts to understand when and why nearly all children in LMICs grow more slowly than expected for their age. Since mean LAZ and stunting prevalence are unsuitable for quantifying the rate and timing of population-average postnatal linear growth faltering, growth delay is recommended for consideration as a preferred metric.

To assess the incidence of delirium and its predictors among adult patients admitted to the intensive care units of comprehensive specialised hospitals in the Amhara region of northwest Ethiopia from 18 October 2024 to 20 February 2025.

A multicentre prospective observational study was conducted.

Four comprehensive specialised hospitals in the Amhara region of northwest Ethiopia, from 18 October 2024 to 20 February 2025.

A total of 351 patients were included in the final analysis during the study period.

The primary outcome measure of this study was the incidence of delirium. Additionally, the study investigated the factors associated with delirium incidence among adult patients admitted to intensive care units.

The incidence of delirium among adult patients in intensive care units was 42.17% (95% CI: 37.08 to 47.42). Pain (adjusted HR (AHR) = 4.74; 95% CI: 2.38 to 9.44), mechanical ventilation (AHR = 2.96; 95% CI: 1.56 to 5.63), age 65 years or older (AHR = 2.18; 95% CI: 1.48 to 3.21) and agitation (Richmond Agitation-Sedation Scale (RASS) ≥1) (AHR = 3.26; 95% CI: 2.09 to 5.09) were statistically significant factors associated with delirium.

In the present study, more than one-third of patients developed delirium. Pain, mechanical ventilation, age 65 or older and agitation (RASS≥1) were significantly associated with delirium occurrence. To reduce the incidence of delirium, the current study recommends treating or preventing pain and agitation. Additionally, special attention should be given to patients receiving mechanical ventilation and those aged 65 or older during care.

To integrate the quantitative and qualitative data collected as part of the PEACH (Procalcitonin: Evaluation of Antibiotic use in COVID-19 Hospitalised patients) study, which evaluated whether procalcitonin (PCT) testing should be used to guide antibiotic prescribing and safely reduce antibiotic use among patients admitted to acute UK National Health Service (NHS) hospitals.

Triangulation to integrate quantitative and qualitative data.

Four data sources in 148 NHS hospitals in England and Wales including data from 6089 patients.

A triangulation protocol was used to integrate three quantitative data sources (survey, organisation-level data and patient-level data: data sources 1, 2 and 3) and one qualitative data source (clinician interviews: data source 4) collected as part of the PEACH study. Analysis of data sources initially took place independently, and then, key findings for each data source were added to a matrix. A series of interactive discussion meetings took place with quantitative, qualitative and clinical researchers, together with patient and public involvement (PPI) representatives, to group the key findings and produce seven statements relating to the study objectives. Each statement and the key findings related to that statement were considered alongside an assessment of whether there was agreement, partial agreement, dissonance or silence across all four data sources (convergence coding). The matrix was then interpreted to produce a narrative for each statement.

To explore whether PCT testing safely reduced antibiotic use during the first wave of the COVID-19 pandemic.

Seven statements were produced relating to the PEACH study objective. There was agreement across all four data sources for our first key statement, ‘During the first wave of the pandemic (01/02/2020-30/06/2020), PCT testing reduced antibiotic prescribing’. The second statement was related to this key statement, ‘During the first wave of the pandemic (01/02/2020-30/06/2020), PCT testing safely reduced antibiotic prescribing’. Partial agreement was found between data sources 3 (quantitative patient-level data) and 4 (qualitative clinician interviews). There were no data regarding safety from data sources 1 or 2 (quantitative survey and organisational-level data) to contribute to this statement. For statements three and four, ‘PCT was not used as a central factor influencing antibiotic prescribing’, and ‘PCT testing reduced antibiotic prescribing in the emergency department (ED)/acute medical unit (AMU),’ there was agreement between data source 2 (organisational-level data) and data source 4 (interviews with clinicians). The remaining two data sources (survey and patient-level data) contributed no data on this statement. For statement five, ‘PCT testing reduced antibiotic prescribing in the intensive care unit (ICU)’, there was disagreement between data sources 2 and 3 (organisational-level data and patient-level data) and data source 4 (clinician interviews). Data source 1 (survey) did not provide data on this statement. We therefore assigned dissonance to this statement. For statement six, ‘There were many barriers to implementing PCT testing during the first wave of COVID-19’, there was partial agreement between data source 1 (survey) and data source 4 (clinician interviews) and no data provided by the two remaining data sources (organisational-level data and patient-level data). For statement seven, ‘Local PCT guidelines/protocols were perceived to be valuable’, only data source 4 (clinician interviews) provided data. The clinicians expressed that guidelines were valuable, but as there was no data from the other three data sources, we assigned silence to this statement.

There was agreement between all four data sources on our key finding ‘during the first wave of the pandemic (01/02/2020-30/06/2020), PCT testing reduced antibiotic prescribing’. Data, methodological and investigator triangulation, and a transparent triangulation protocol give validity to this finding.

Randomised controlled trials have aimed to assess the effectiveness of stereotactic ablative radiotherapy (SABR) with curative intent versus surgical resection for individuals diagnosed with early-stage non-small cell lung cancer (NSCLC) but have failed to recruit sufficient numbers of patients. Non-randomised studies for early-stage NSCLC have reported mixed outcomes following curative SABR versus surgical resection, but did not fully address confounding by indication. The Surgery Or RadioTherapy for early-stage cancer study (SORT) will assess the comparative effectiveness of SABR with curative intent versus surgical resection for NSCLC with a target trial emulation approach, as this can reduce biases in observational studies that aim to estimate the causal effect of interventions.

The SORT study will use the National Cancer Registry for individuals diagnosed with early-stage NSCLC in England during 2015–2020 (inclusive) who received SABR with curative intent or surgical resection. These data will be linked to Hospital Episode Statistics, National Radiotherapy Data Set and the Systemic Anti-Cancer Therapy dataset to obtain information on clinical and sociodemographic characteristics and the treatment received. This target trial emulation will define study population eligibility criteria and regimens for SABR with curative intent and surgical resection. We will reduce the risk of residual confounding with instrumental variable analyses that will exploit geographical variation across the National Health Service in England in the use of SABR with curative intent versus surgical resection for early-stage NSCLC. The primary outcome will be 3-year all-cause mortality after treatment initiation. Secondary outcomes will include 3-month, 6-month, 12-month and 24-month all-cause and lung-cancer mortality, time to death, numbers of hospitalisations, incremental costs and incremental cost-effectiveness.

Ethical approval was obtained from the London School of Hygiene and Tropical Medicine Research Ethics Committee (reference number 29 717–1). Results will be disseminated to clinicians, patients, policy-makers and researchers.

To identify and contextualise evidence-based strategies for implementing deprescribing practices at different levels of healthcare in Brazil, through the development of an evidence brief for policy that includes stakeholder deliberation and considers barriers, facilitators and equity aspects.

This protocol outlines the development of an evidence brief for policy using a mixed-methods design. It involves synthesising evidence for health policies by integrating global research and local evidence through three stages: stakeholder exchange, evidence brief development and external endorsement. The Supporting Policy-Relevant Reviews and Trials tools for evidence-informed health policies will guide both the synthesis of strategies and the facilitation of deliberative dialogues. The synthesis will encompass evidence from systematic reviews and meta-analysis on deprescribing strategies across healthcare levels, focusing on effectiveness, harms, costs, perceptions, barriers, facilitators and equity. Studies proposing strategies not yet implemented will be excluded. Study selection and data extraction will be conducted independently and in duplicate. The methodological quality of included studies will be assessed using the A Measurement Tool for Assessing the Methodological Quality of Systematic Reviews-2 criteria. Synthesised evidence will be used to develop evidence-based strategies, which will then be presented in deliberative dialogues for endorsement by stakeholders and adaptation to the Brazilian context. Endorsement rates will be classified as high, moderate or low based on predefined criteria.

This study was approved by the University of Sorocaba Research Ethics Committee (certificate 82098324.7.0000.5500). Informed consent will be obtained from all participants. Findings will be disseminated through peer-reviewed publications and conference presentations.
