Socioeconomic Status and Stroke: A Review of the Latest Evidence on Inequalities and Their Drivers.

The latest research on socioeconomic status (SES) and stroke continues to demonstrate that individuals with low SES are at a higher risk of stroke, receive lower-quality care, and experience poorer outcomes. Despite growing evidence on the impact of SES on stroke, gaps remain in understanding the underlying mechanisms and the influence of SES in different contexts, particularly in low- and middle-income countries. This narrative review builds upon our previous reviews from 2006 to 2015, focusing on studies published since 2015 to update on the influence of SES on stroke.

A scoping review of stroke registers in Sub-Saharan Africa.

Background: Stroke registers are recommended as a key priority by the Lancet Neurology World Stroke Organization Commission for Stroke, 2023, and the African Stroke Leaders' Summit, 2022.

Aims: This scoping review aims to map where stroke registers have been implemented in Sub-Saharan Africa (SSA). The article then compares and critiques the methods and definitions used and summarizes key results from the registers.

Quality of life and quality-adjusted life years after stroke in Sierra Leone.

Background: Stroke is a leading cause of mortality and negatively affects health-related quality of life (HRQoL). HRQoL after stroke is understudied in Africa and there are no reports of quality-adjusted life years after stroke (QALYs) in African countries. We determined the impact of stroke on HRQoL after stroke in Sierra Leone.

The feasibility, repeatability, validity and responsiveness of the EQ-5D-3L in Krio for patients with stroke in Sierra Leone.

Objectives: To assess the feasibility, repeatability, validity and responsiveness of the EQ-5D-3L in Krio for patients with stroke in Sierra Leone, the first psychometric assessment of the EQ-5D-3L to be conducted in patients with stroke in Sub Saharan Africa.

Methods: A prospective stroke register at two tertiary government hospitals recruited all patients with the WHO definition of stroke and followed patients up at seven days, 90 days and one year post stroke. The newly translated EQ-5D-3L, Barthel Index (BI), modified Rankin Scale (mRS) and National Institute of Health Stroke Scale (NIHSS), a measure of stroke severity, were collected by trained researchers, face to face during admission and via phone at follow up.

A qualitative study examining the health system's response to COVID-19 in Sierra Leone.

The paper examines the health system's response to COVID-19 in Sierra Leone. It aims to explore how the pandemic affected service delivery, health workers, patient access to services, leadership, and governance. It also examines to what extent the legacy of the 2013-16 Ebola outbreak influenced the COVID-19 response and public perception.

Improving the quality of COVID-19 care in Sierra Leone: A modified Delphi process and serial nationwide assessments of quality of COVID-19 care in Sierra Leone.

Introduction: Improving the quality of care that patients receive is paramount to improving patient outcomes and engendering trust during infectious disease outbreaks. Whilst Quality Improvement (QI) is well established to drive improvement in routine care and in health systems, there are fewer reports of its use during infectious disease outbreaks.

Methods: A modified Delphi process was undertaken to create a standardized assessment tool for the quality of COVID-19 care in Sierra Leone.

Stroke in Sierra Leone. the stroke risk factors for people with HIV: A prospective case-control study.

Background: HIV infection rates are relatively low in Sierra Leone and in West Africa but the contribution of HIV to the risk factors for stroke and outcomes is unknown. In this study, we examined stroke types, presentation, risk factors and outcome in HIV stroke patients compared with controls.

Methods: We used data from the Stroke in Sierra Leone Study at 2 tertiary hospitals in Freetown, Sierra Leone.

All-cause mortality of hospitalised patients with suspected COVID-19 in Sierra Leone: a prospective cohort study.

Objectives: To study the mortality of patients with COVID-19 in Sierra Leone, to explore the factors associated with mortality during the COVID-19 pandemic and to highlight the complexities of treating patients with a novel epidemic disease in a fragile health system.

Study Design: A prospective single-centre cohort study. Data were extracted from paper medical records and transferred onto an electronic database.

Association between ambulance prehospital time and maternal and perinatal outcomes in Sierra Leone: a countrywide study.

Introduction: Sierra Leone, one of the countries with the highest maternal and perinatal mortality in the world, launched its first National Emergency Medical Service (NEMS) in 2018. We carried out a countrywide assessment to analyse NEMS operational times for obstetric emergencies in respect the access to timely essential surgery within 2 hours. Moreover, we evaluated the relationship between operational times and maternal and perinatal mortality.

The impact of the COVID-19 pandemic on hospital utilisation in Sierra Leone.

Introduction: The COVID-19 pandemic has adversely affected health systems in many countries, but little is known about effects on health systems in sub-Saharan Africa. This study examines the effects of COVID-19 on hospital utilisation in a sub-Saharan country, Sierra Leone.

Methods: Mixed-methods study using longitudinal nationwide hospital data (admissions, operations, deliveries and referrals) and qualitative interviews with healthcare workers and patients.

Improving Access to Healthcare in Sierra Leone: The Role of the Newly Developed National Emergency Medical Service.

We aim to evaluate whether the first National Emergency Medical Service (NEMS) improved access to hospital care for the people of Sierra Leone. We performed an interrupted time-series analysis to assess the effects of NEMS implementation on hospital admissions in 25 facilities. The analysis was also replicated separately for the area of Freetown and the rest of the country.

A Prospective Stroke Register in Sierra Leone: Demographics, Stroke Type, Stroke Care and Hospital Outcomes.

Stroke is the second most common cause of adult death in Africa. This study reports the demographics, stroke types, stroke care and hospital outcomes for stroke in Freetown, Sierra Leone. A prospective observational register recorded all patients 18 years and over with stroke between May 2019 and April 2020.

Development of a Pediatric Ebola Predictive Score, Sierra Leone.

We compared children who were positive for Ebola virus disease (EVD) with those who were negative to derive a pediatric EVD predictor (PEP) score. We collected data on all children <13 years of age admitted to 11 Ebola holding units in Sierra Leone during August 2014-March 2015 and performed multivariable logistic regression. Among 1,054 children, 309 (29%) were EVD positive and 697 (66%) EVD negative, with 48 (5%) missing.

Ebola Holding Units at government hospitals in Sierra Leone: evidence for a flexible and effective model for safe isolation, early treatment initiation, hospital safety and health system functioning.

The 2014-2015 West African outbreak of Ebola Virus Disease (EVD) claimed the lives of more than 11,000 people and infected over 27,000 across seven countries. Traditional approaches to containing EVD proved inadequate and new approaches for controlling the outbreak were required. The Ministry of Health & Sanitation and King's Sierra Leone Partnership developed a model for Ebola Holding Units (EHUs) at Government Hospitals in the capital city Freetown.

Novel surveillance methods for the control of Ebola virus disease.

The unprecedented scale of the 2013-2016 West African Ebola virus disease (EVD) outbreak was in a large part due to failings in surveillance: contacts of confirmed cases were not systematically identified, monitored and diagnosed early, and new cases appearing in previously unaffected communities were similarly not rapidly identified, diagnosed and isolated. Over the course of this epidemic, traditional surveillance methods were strengthened and novel methods introduced. The wealth of experience gained, and the systems introduced in West Africa, should be used in future EVD outbreaks, as well as for other communicable diseases in the region and beyond.

Acute hepatitis E virus infection in a migrant population in North East Italy: A retrospective analysis.

Objective: To study the epidemiological and clinical features of Hepatitis E Virus (HEV) infection in a migrant population.

Methods: We performed a retrospective chart review, identifying a cohort of 21 symptomatic patients of migrant origin with confirmed HEV infection admitted in the period between January 1995-November 2014.

Results: 20 (95%) patients came from South Asian countries highly endemic for HEV, all positive for HEV genotype 1.

Risk in the "Red Zone": Outcomes for Children Admitted to Ebola Holding Units in Sierra Leone Without Ebola Virus Disease.

We collected data on 1054 children admitted to Ebola Holding Units in Sierra Leone and describe outcomes of 697/1054 children testing negative for Ebola virus disease (EVD) and accompanying caregivers. Case-fatality was 9%; 3/630 (0.5%) children discharged testing negative were readmitted EVD-positive.

Quantifying the risk of nosocomial infection within Ebola Holding Units: a retrospective cohort study of negative patients discharged from five Ebola Holding Units in Western Area, Sierra Leone.

Objectives: A central pillar in the response to the 2014 Ebola virus disease (EVD) epidemic in Sierra Leone was the role of Ebola Holding Units (EHUs). These units isolated patients meeting a suspect case definition, tested them for EVD, initiated appropriate early treatment and discharged negative patients to onward inpatient care or home. Positive patients were referred to Ebola Treatment Centres.

Ebola Virus Disease in Children, Sierra Leone, 2014-2015.

Little is known about potentially modifiable factors in Ebola virus disease in children. We undertook a retrospective cohort study of children <13 years old admitted to 11 Ebola holding units in the Western Area, Sierra Leone, during 2014-2015 to identify factors affecting outcome. Primary outcome was death or discharge after transfer to Ebola treatment centers.

Ebola response in Sierra Leone: The impact on children.

The West African Ebola virus disease (EVD) outbreak is the largest ever seen, with over 28,000 cases and 11,300 deaths since early 2014. The magnitude of the outbreak has tested fragile governmental health systems and non-governmental organizations (NGOs) to their limit. Here we discuss the outbreak in the Western Area of Sierra Leone, the shape of the local response and the impact the response had on caring for children suspected of having contracted EVD.

Application of Ultrasonography in the Diagnosis of Infectious Diseases in Resource-Limited Settings.

Ultrasound (US) has vast potential in the field of infectious diseases, especially so in resource-limited settings. Recent technological advances have increased availability and access to ultrasound in low-resource settings, where the burden of infectious diseases is greatest. This paper collates the evidence for the utilization of ultrasound and evaluates its effectiveness in the diagnosis and management of a range of infectious diseases.
