The prognostic value of a screening tool for psychological risk factors after mild traumatic brain injury: prospective studies in Canada and New Zealand

Por: Mikolic · A. · Snell · D. L. · Theadom · A. · Faulkner · J. W. · Zemek · R. · Silverberg · N. D.
Objective

To investigate the prognostic value of the Subgroups for Targeted Treatment (STarT) Screening Tool adapted for concussion (STarT-C) on persistent symptoms and disability at 6–9 months following mild traumatic brain injury (mTBI).

Design

Secondary analysis of two prospective studies: an observational cohort study in New Zealand and usual care control arm of a clinical trial in Canada (ClinicalTrials.gov Registry (NCT04704037)).

Setting

Participants in the New Zealand cohort were recruited from concussion clinics (five sites) and those in the Canadian cohort were recruited from emergency departments/urgent care centres (eight sites).

Participants

New Zealand participants (n=93, median age 37 years, 60% women) were assessed at median=6 weeks post-injury (T1) and 6 months later (T2). Canadian participants (n=223, median age 38 years, 56% women) were assessed at median=2 weeks (T1) and 6 months later (T2).

Main outcome measures

Symptoms at T2 were assessed using the validated Rivermead Postconcussion Symptoms Questionnaire (RPQ) and disability using the WHO Disability Assessment Schedule 2.0 12-item Interview.

Results

In linear regression analyses, the STarT-C predicted symptom burden (R2=18–36%) and disability (R2=15–18%) at T2 in both cohorts. While the additional prognostic value over and above baseline variables was substantial (delta R2 8–40%), the additional prognostic value over the RPQ at T1 was variable and generally lower (delta R2=1–9%).

Conclusion

The STarT-C—a brief screening tool—predicted persistent symptoms and disability in adults following mTBI. The incremental prognostic value of the STarT-C over the RPQ may be variable, but regardless, the tool may be useful for identifying those at risk of prolonged recovery who may benefit from early psychological intervention.

Assessing the global variation in patient characteristics, management and short-term outcomes of spontaneous intracranial haemorrhage worldwide: a protocol for a global observational prospective multicentre study (the PLOT-ICH study)

Introduction

Stroke is the second leading cause of death worldwide, with the greatest burden in low- and middle-income countries (LMICs). Haemorrhagic stroke or spontaneous intracranial haemorrhage (sICH), including intraparenchymal haemorrhage (IPH) and subarachnoid haemorrhage (SAH), has the highest mortality and morbidity. Local management practices for haemorrhagic stroke vary greatly between geographical regions. The Planetary Outcomes after Intracranial Haemorrhage study aims to provide a global snapshot of the patient characteristics, processes of care and short-term outcomes of patients being treated for sICH across high- and low-income settings. It will also describe variation seen in care processes and available resources and time delays to receiving care. A greater understanding of the current state of sICH care is essential to identify possible interventions and targets for improved standards of care in all settings.

Methods and analysis

We describe a planned prospective, multicentre, international observational cohort study of patients admitted to hospital for management of sICH. We will include patients of all ages presenting to hospital with imaging evidence of sICH (IPH, intraventricular haemorrhage and/or SAH). The study will collect patient, care process and short-term outcome data, following patients for up to 30 days (or until discharge or death, whichever occurs first). Any centre globally where patients with sICH are admitted and managed can participate, targeting a sample size of 712 patients. The study will recruit centres worldwide through pre-existing research networks and by dissemination through neurosurgical and stroke conferences and courses. Each participating centre will complete a site questionnaire alongside patient data collection.

Ethics and dissemination

The study has received ethical approval by the University of Cambridge (PRE.2024.070). Participating centres will also confirm that they have undergone all necessary local governance procedures prior to starting local data collection. The findings will be disseminated via open access peer-reviewed journals, relevant conferences and other professional networks and lay channels, including the study website (https://plotich.org/) and social media channels (@plotichstudy).

Effectiveness and cost-effectiveness of community-based TB screening algorithms using computer-aided detection (CAD) technology alone compared with CAD combined with point-of-care C reactive protein testing in Lesotho and South Africa: protocol for a pair

Por: Signorell · A. · van Heerden · A. · Ayakaka · I. · Jacobs · B. K. · Antillon · M. · Tediosi · F. · Verjans · A. · Brugger · C. · Harkare · H. V. · Labhardt · N. D. · Bosman · S. · Kamele · M. · Keitseng · M. · Madonsela · T. · Kurscheid · J. · Muhairwe · J. · Keter · A. K. · Murphy · K.
Introduction

Tuberculosis (TB) remains a significant public health challenge in many African communities, where underreporting and underdiagnosis are prevalent due to barriers in accessing care and inadequate diagnostic tools. This is particularly concerning in hard-to-reach areas with a high burden of TB/HIV co-infection, where missed or delayed diagnoses exacerbate disease transmission, increase mortality and lead to severe economic and health consequences. To address these challenges, it is crucial to evaluate innovative, cost-effective, community-based screening strategies that can improve early detection and linkage to care.

Methods and analysis

We conduct a prospective, community-based, diagnostic, pragmatic trial in communities of the Butha Buthe District in Lesotho and the Greater Edendale area of Msunduzi Municipality, KwaZulu-Natal in South Africa to compare two strategies for population-based TB screening: computer-aided detection (CAD) technology alone (CAD4TBv7 approach) versus CAD combined with point-of-care C reactive protein (CRP) testing (CAD4TBv7-CRP approach). Following a chest X-ray, CAD produces an abnormality score, which indicates the likelihood of TB. Score thresholds informing the screening logic for both approaches were determined based on the WHO’s target product profile for a TB screening test. CAD scores above a threshold prespecified for the CAD4TBv7 approach indicate confirmatory testing for TB (Xpert MTB/RIF Ultra). For the CAD4TBv7-CRP approach, a CAD score within a predefined window requires the conduct of the second screening test, CRP, while a score above the respective upper threshold is followed by Xpert MTB/RIF Ultra. A CRP result above the selected cut-off also requires a confirmatory TB test. Participants with CAD scores below the (lower) threshold and those with CRP levels below the cut-off are considered screen-negative. The trial aims to compare the yield of detected TB cases and cost-effectiveness between two screening approaches by applying a paired screen-positive design. 20 000 adult participants will be enrolled and will receive a posterior anterior digital chest X-ray which is analysed by CAD software.

Ethics and dissemination

The protocol was approved by National Health Research Ethics Committee in Lesotho (NH-REC, ID52-2022), the Human Sciences Research Council Research Ethics Committee (HSRC REC, REC 2/23/09/20) and the Provincial Health Research Committee of the Department of Health of KwaZulu-Natal (KZ_202209_022) in South Africa and from the Swiss Ethics Committee Northwest and Central Switzerland (EKNZ, AO_2022–00044).

What are the factors associated with alcohol, cigarette and marijuana use among adolescents in Africa? Evidence from the Global School-based Health Survey

Por: Pokothoane · R. · Argefa · T. G. · Tsague · J. D. · Mdege · N. D.
Objectives

To provide comprehensive estimates of the prevalence of psychoactive substance use, specifically alcohol, cigarettes and marijuana, and factors associated with their use among school-going adolescents in 25 African countries.

Design and methods

We used a pooled cross-sectional dataset from the publicly available Global School-based Health Survey (GSHS) from 25 African countries. We used descriptive statistics to estimate the prevalence of alcohol, cigarette and marijuana use as well as their dual use among adolescents aged 11–16 years. Additionally, we used logistic regressions to model factors associated with the use of each substance, with adjusted Odds Ratios (aORs) and their 95% Confidence Intervals (CIs) as the measures of association.

Setting and participants

The study focused on school-going adolescents aged 11–16 years in 25 African countries that have conducted the GSHS between 2003 and 2017.

Outcome measures

The key outcome measure is the proportion of adolescents who have used a specific substance in the past 30 days. These substances include: (1) alcohol, (2) cigarettes, (3) marijuana, (4) alcohol and cigarettes, (5) cigarettes and marijuana and (6) alcohol and marijuana.

Results

The prevalence of alcohol use among adolescents was 9.5% (95% CI 8.4% to 10.7%), that of cigarette smoking was 6.2% (95% CI 5.0% to 7.6%), and it was 3.4% (95% CI 2.7% to 4.2%) for marijuana. The prevalence of dual use of alcohol and cigarettes was 3.1% (95% CI 2.4% to 3.9%), that of alcohol and marijuana was 2.0% (95% CI 1.5% to 2.5%), and it was 1.4% (95% CI 1.1% to 1.8%) for cigarettes and marijuana. The prevalence of cigarette smoking was significantly higher among boys than girls. However, there was no statistically significant difference in the prevalence of alcohol or marijuana by sex. Having parents who smoke any tobacco products, being bullied, missing school without permission and experiencing sadness and hopelessness were positively associated with being a current user, irrespective of substance type.

Conclusions

There is a need for comprehensive, current data on substance use among adolescents. Interventions that tackle bullying, reduce school absenteeism, build resilience against difficult situations and increase self-efficacy to resist the use of these substances have the potential to curb substance use among adolescents in Africa.

Non-invasive electrophysiological monitoring vs conventional monitoring during labour in a tertiary obstetric care centre in the Netherlands: study protocol of a cohort intervention random sampling study (NIEM-II study)

Introduction

Conventional cardiotocography (CTG) has been used extensively to monitor the fetal condition during labour. However, conventional non-invasive monitoring is limited by the difficulty of obtaining an adequate signal quality, particularly in the case of obese parturients. Furthermore, the rate of operative deliveries keeps rising despite the ability for conventional intrapartum monitoring. Electrophysiological monitoring is an alternative technique that has been developed over the past decades to improve signal quality. This non-invasive, transabdominal and wireless alternative measures fetal heart rate by fetal electrocardiography (NI-fECG), and uterine activity by electrohysterography (EHG). Both NI-fECG and EHG have been proven to be more accurate and reliable than conventional non-invasive methods and are less affected by maternal Body Mass Index. Nevertheless, it is still unknown whether electrophysiological intrapartum monitoring leads to better obstetric and neonatal outcomes. This study aims to investigate whether electrophysiological monitoring during labour affects the number of operative interventions compared with conventional monitoring during labour.

Methods and analysis

This is a single-centre cohort intervention random sampling study which will be performed in a tertiary obstetric care centre. In total, 3471 term pregnant women with a singleton fetus in cephalic position and indication for continuous fetal monitoring during labour will be included. Eligible women will be prospectively included in the cohort for conventional monitoring. From these women, 90.9% of women will be randomly sampled and will be offered electrophysiological monitoring. A historical cohort of an additional 2100 women who received conventional monitoring will be added to the conventional group. This historical cohort was collected between April 2019 and February 2023. The primary outcome will be the number of operative interventions during labour. Secondary outcome measures include maternal and neonatal outcomes, patient and healthcare professional perspectives and costs.

Ethics and dissemination

This study received approval from the Medical Ethics Committee of Máxima Medical Centre (W22.071) on 1 November 2023. All participants will provide informed consent prior to data collection. Results of the study will be disseminated in peer-reviewed scientific journals and conference presentations.

Trends over time in age-standardised prevalence of cardiometabolic risk factors in Senegal between 1975 and 2021 by sex: an ecological study from the WHO Inequality Data Repository

Por: Ka · M. M. · Gaye · N. D. · Tukakira · J. · Kyem · D. · Gary-Webb · T. · Sattler · L. · Jobe · M. · Gaye · B.
Objective

We aimed to analyse the time trends of cardiometabolic risk factors in Senegal from 1975 to 2021.

Design

Ecological study of publicly available data from the WHO Health Inequality Data Repository.

Setting

Disaggregated datasets from publicly available sources.

Primary outcome

Trends of age-standardised prevalence rates, stratified by sex for tobacco use, obesity, diabetes and hypertension, were analysed for significance.

Participants

Only data from Senegal were included in this study.

Results

Tobacco use decreased in both sexes between 2000 and 2021, from 1.7% to 0.7% (p value 0.04) in females and from 28.1% to 12.8% (p value 0.04) in males. Obesity and overweight increased in both sexes between 1975 and 2016, from 14.2% to 35.9% (p value

Conclusion

Our findings highlight changes in cardiometabolic risk factors in Senegal between 1975 and 2020 by sex. While tobacco use declined, rates of obesity, diabetes and hypertension increased. These findings underscore the need for strategies to mitigate this increase in cardiometabolic risk factors and a consequential rise in non-communicable diseases.

Survival status and predictors of mortality among patients with breast cancer in Ethiopia: a systematic review and meta-analysis

Por: Aragie · H. · Adugna · D. G. · Negash · H. K. · Maru · L. · Baye · N. D.
Objectives

This study aimed to evaluate survival outcomes and identify key mortality predictors among patients with breast cancer in Ethiopia.

Study design

A systematic review and meta-analysis.

Study participants

The study used 11 primary studies, involving a total of 4131 participants.

Data sources

We searched PubMed, Embase, Web of Science, Scopus and Google Scholar until 7 March 2025, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.

Eligibility criteria for selecting studies

All observational studies that had reported the survival status and/or at least one predictor of mortality of women patients with breast cancer were considered.

Data extraction and synthesis

Three independent reviewers (HA, HKN and DGA) used a structured data extraction form to extract the data. To compute the pooled survival and mortality rates, the survival rates at different observation periods and the mortality rates reported in the included studies were extracted.

Results

Eleven studies were analysed. All studies were of good quality based on Newcastle-Ottawa Scale. However, heterogeneity was high (I² = 98.2%, p=0.00). Funnel plots showed significant publication bias. The Grading of Recommendations, Assessment, Development, and Evaluations assessment indicated moderate certainty for mortality rates and predictors, limited by heterogeneity and regional data gaps. The pooled mortality rate was 36% (95% CI: 25% to 46%). The survival rates at 1, 3 and 5 years were 85% (95% CI: 75% to 96%), 66% (95% CI: 48% to 84%) and 22% (95% CI: 1% to 43%), respectively. Key mortality predictors included advanced clinical stage (Adjusted Hazard Ratio (AHR): 4.14; CI: 2.53 to 6.78), rural residence (AHR: 1.65; 95% CI: 1.27 to 2.14), positive lymph node status (AHR: 2.85; 95% CI: 1.50 to 5.44), no hormonal therapy (AHR: 2.02; 95% CI: 1.59 to 2.56), histologic grade III (AHR: 1.76; 95% CI: 1.29 to 2.41), hormone receptor negativity (AHR: 1.54; 95% CI: 1.05 to 2.25) and comorbidities (AHR: 2.24; 95% CI: 1.41 to 3.56).

Conclusion

Breast cancer in Ethiopia poses a high mortality rate primarily due to late-stage diagnosis, rural residency, histologic grade III, positive lymph node status and comorbidities. To improve survival outcomes, it is crucial to expand access to early screening, particularly in rural areas, implement comprehensive treatment protocols and strengthen healthcare infrastructure to address these critical factors.

Cost drivers and feasibility of a hospital-at-home programme for geriatric care in northeastern Mexico: a retrospective observational study

Objective

The primary objective was to evaluate factors influencing the cost of a ‘hospital at home’ (HAH) for geriatric patients in a Northeastern Mexican hospital. Secondarily to evaluate the per capita global cost-effectiveness compared with traditional hospital care.

Design

This retrospective analysis examined the costs incurred by geriatric patients in an HAH programme from February to December 2022

Setting

We collected data from clinical records and assessed medication and procedure costs through the hospital’s financial department. Costs for traditionally hospitalised patients were reviewed for comparison.

Participants

Subjects of both genders aged 70 and older who were treated in HAH during 2022 and hospitalised subjects with the same age and gender treated in the same period.

Intervention: NA

Primary and secondary outcome measures

Primary outcome: factors that influence costs in HAH. Secondary, global per capita cost comparison between HAH and hospital care.

Results

We examined the expenses associated with 416 home visits to 49 patients in the HAH programme. The main factors influencing the programme’s overall cost were medical care and procedure-related disorders (β=0.333, p=0.002), sleep-regulators (β=0.561, p

Conclusions

This study highlights that the main factors influencing the HAH programme’s costs include medical care and procedure-related disorders, as well as medication extensively used in the elderly population. Additionally, we demonstrated the cost-effectiveness of the HAH programme, which produces substantial savings and is a financially viable alternative to traditional hospital care.
