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. We calculated QALYs at 1 year post-stroke and determined sociodemographic and clinical variables associated with HRQoL and QALYs in this population. A prospective stroke register was established at the two-principal adult tertiary government hospitals in Freetown, Sierra Leone. Participants were followed up at 7, 90 days, and 1 year post-stroke to capture all-cause mortality and EQ-5D-3L data. QALYs were calculated at the patient level using EQ-5D-3L utility values and survival data from the register, following the area under the curve method. Utilities were based on the UK and Zimbabwe (as a sensitivity analysis) EQ-5D value sets, as there is no Sierra Leonean or West African value set. Explanatory models were developed based on previous literature to assess variables associated with HRQoL and QALYs at 1 year after stroke. To address missing values, Multiple Imputation by Chained Equations (MICE), with linear and logistic regression models for continuous and binary variables, respectively, were used. EQ-5D-3L data were available for 373/460 (81.1%), 360/367 (98.1%), and 299/308 (97.1%) participants at 7, 90 days, and 1 year after stroke. For stroke survivors, median EQ-5D-3L utility increased from 0.20 (95% CI: -0.16 to 0.59) at 7 days post-stroke to 0.76 (0.47 to 1.0) at 90 days and remained stable at 1 year 0.76 (0.49 to 1.0). Mean QALYs at 1 year after stroke were 0.28 (SD: 0.35) and closely associated with stroke severity. Older age, lower educational attainment, patients with subarachnoid hemorrhage and undetermined stroke types all had lower QALYs and lower HRQoL, while being the primary breadwinner was associated with higher HRQoL. Sensitivity analysis with the Zimbabwe value set did not significantly change regression results but did influence the absolute values with Zimbabwe utility values being higher, with fewer utility values less than 0. We generated QALYs after stroke for the first time in an African country. QALYs were significantly lower than studies from outside Africa, partially explained by the high mortality rate in our cohort. Further research is needed to develop appropriate value sets for West African countries and to examine QALYs lost due to stroke over longer time periods.

Abstract Background: Access to medical products of the required efficacy, quality and safety is essential for everyone’s health and wellbeing. To achieve this milestone, every country needs a robust and strong performing National Regulatory Authority (NRA) that is independent and outcome oriented. With the help of the World Health Organization (WHO), the global benchmarking tool is the gold standard used to assess the regulatory capacity of NRAs. Objectives: This study assessed the capacity of the National Medicines Regulatory Authority in Sierra Leone to perform its regulatory functions. Methods: This descriptive cross-sectional study used both qualitative and quantitative approaches. A self-administered questionnaire was used for the quantitative approach, and the qualitative aspect consisted of a desk review looking at key regulatory documents such as laws, regulations, policies, guidelines, standard operating procedures and reports. The data collection tool used was the WHO global benchmarking tool (GBT) for “Evaluation of National Regulatory System of Medical Product Version VI. Results: The majority of the participants had a postgraduate degree (60%), and 72% had over 10 years of experience working at the NRA. Out of 251 sub-indicators assessed, 85 (34%) sub-indicators were fully implemented. Of the eight (8) functions assessed, sub-indicators related to clinical trial oversight and vigilance were the most common, with 67% and 62%, respectively. Of the 9 indicators assessed, 79% of the sub-indicators that are related to quality and risk management were implemented. The results of this study showed that PBSL operates at maturity level 1. The absence of laws and regulations that give PBSL the mandate to perform its regulatory functions was a major challenge even though other indicators were met. The study reported other challenges toward effective functioning, including but not limited to a lack of sufficient staff, weak enforcement of the sale of medicines and a poorly equipped quality control laboratory.

ABSTRACT A good collection of existing literature provides limited reflection on classifying post-conflict countries as being ‘peaceful’. This is especially so, as the period following the end of a civil war is normally characterised, as a period of ‘peace’, thereby equating peace to the silence of the guns. Such an understanding of what constitutes peace in post-conflict settings is problematic. This is because, societies in transition, are usually plagued with a plethora of challenges, with the legacies of war normally shaping the resurgence of violence in other forms. Additionally, complex transitions of violence and aggression, which reflect the socio-economic and political gyrations of a society redefining itself, and reconstructing its values are seen in most post-conflict contexts. Thus, using the case of Sierra Leone, this paper argues that some post-conflict settings experience negative peace, and diverse forms of violence that usually render communities unsafe, insecure and not peaceful. Thus, boxing societies in a bracket of being peaceful, because of the end of a violent civil war, limits what peace means in a specific contextual sense. It even undermines the potential for a broader approach towards understanding how the emerging forms of violence and aggression could be addressed.

BackgroundInfectious disease outbreaks like Ebola and Covid-19 are increasing in frequency. They may harm reproductive, maternal and newborn health (RMNH) directly and indirectly. Sierra Leone experienced a sharp deterioration of RMNH during the 2014–16 Ebola epidemic. One possible explanation is that donor funding may have been diverted away from RMNH to the Ebola response.MethodsWe analysed donor-reported data from the Organisation for Economic Cooperation and Development (OECD)’s Creditor Reported System (CRS) data for Sierra Leone before, during and after the 2014–16 Ebola epidemic to understand whether aid flows for Ebola displaced aid for RMNH. We estimated aid for Ebola using key term searches and manual review of CRS records. We estimated aid for RMNH by applying the Muskoka-2 algorithm to the CRS and analysing CRS purpose codes.ResultsWe find substantial increases in aid to Sierra Leone (from $484 million in 2013 to $1 billion at the height of the epidemic in 2015), most of which was earmarked for the Ebola response. Overall, Ebola aid was additional to RMNH funding. RMNH aid was sustained during the epidemic (at $42 m per year) and peaked immediately after (at $77 m in 2016). There is some evidence of a small displacement of RMNH aid from the UK during the period when its Ebola funding increased.ConclusionsModest changes to RMNH donor aid patterns are insufficient to explain the severe decline in RMNH indicators recorded during the outbreak. Our findings therefore suggest the need for substantial increases in routine aid to ensure that basic RMNH services and infrastructure are strong before an epidemic occurs, as well as increased aid for RMNH during epidemics like Ebola and Covid-19, if reproductive, maternal and newborn healthcare is to be maintained at pre-epidemic levels.

Energy systems modelling plays a pivotal role in understanding and optimizing complex energy systems. By integrating various factors such as energy demand, supply, infrastructure, and environmental considerations, energy systems modelling provides valuable insights for policymakers, industry stakeholders, and researchers. This can be key to informing stakeholder and policy decisions and facilitate the mobilisation of capital and market development to support the development of the energy sector. This article presents the data, assumptions, and related calculations used for the development of a national scale power system model for Sierra Leone. The focus of the model was a techno-economic analysis of specific hydropower expansion plans. Where possible, this data has been collected from publicly available sources such as scientific literature, feasibility studies, international databases, data from existing modelling efforts in Sierra Leone, and local stakeholders. The collection of the data, development of the model, and creation of scenarios was done in collaboration with the Ministry of Energy in Sierra Leone and verified by a broad range of stakeholders. The following paper outlines the key data presented in the full database which can be accessed through the URL found in the Specifications Table.

ABSTRACT The COVID-19 pandemic has amplified discussions on emergency vaccine deployment strategies, with current perspectives often neglecting extensive community involvement in ethical, logistical and political aspects. Existing social science literature predominantly delves into factors influencing trust, overlooking the untapped potential for community engagement. Our study examines community preparedness in Sierra Leone’s Kambia District, exploring diverse viewpoints on vaccine deployment strategies, emphasising Ebola and COVID-19 vaccinations. Utilising extensive ethnographic research from the Ebola vaccine trials (EBOVAC Salone) conducted in Kambia District from 2015 to 2021, including participant observation and tailored focus group discussions, we investigated various deployment scenarios with community leaders and citizens. Our findings underscore the multifaceted contributions of social science research with communities in shaping emergency vaccination strategies. These contributions span logistical insights, aligning campaigns with local livelihoods and social structures, and grounded ethical concerns assessing social justice outcomes across epidemic scenarios. This study emphasises the imperative of integrating discussions on vaccine confidence and deployment. It highlights communities’ proficiency in epidemiological reasoning and their ability to bring this in conversation with salient socio-cultural, economic and religious dimensions. We therefore promote the cultivation of public dialogue, collaborative creation of impactful vaccination initiatives alongside relevant communities in recognition of their invaluable perspectives .

Despite the advancement in therapy, breast cancer still remains the most common malignancy in women globally due in part to its heterogeneity. Triple-negative breast cancer (TNBC) represents up to 20% of all breast cancer variants, an aggressive disease with poorer outcomes compared to other breast cancer subtypes. No targeted therapies are currently approved for TNBC, and newer treatment approaches are seriously needed. Androgen receptor (AR), another hormonal receptor, is often expressed in breast cancer, and its role depends on the relative levels of circulating estrogens and androgens. This study aimed to assess the expression of AR in breast cancer in a tertiary hospital in Ghana. Immunohistochemical staining for AR was performed on tissue microarray (TMA) blocks, of which estrogen receptor, progesterone receptor, and Her-2/neu had already been done. 197 cases were suitable for the study. Results from the immunostaining were analyzed using the SPSS version 23 for descriptive statistics and correlations (χ2 and Pearson tests). 197 TMA cases were used. TNBCs constitute 61.9% of the cancers. The majority of these tumors were grade III, ductal carcinoma NST. The mean age was 49.86 ± 14.09, and the modal age group was 40-49 years. Our cases showed 23% AR expression in triple-negative cancers. The study also established that AR is more frequently expressed in low-grade tumors compared to high-grade ones. There is an appreciable level of AR expression in our cases; however, most are quadruple negative. However, AR is more frequently expressed in low-grade tumors than high-grade ones.

ObjectiveTo examine the prevalence of alcohol use and its associated factors among in-school adolescents in Sierra Leone.DesignData for the study was sourced from the 2017 Sierra Leone Global School-Based Student Health Survey, a nationally representative survey conducted among in-school adolescents aged 10–19 years using a multistage sampling methodology. Percentages were used to present the prevalence of alcohol use among in-school adolescents. Multivariable binary logistic regression analysis was performed to examine the factors associated with alcohol use among in-school adolescents. The results were presented using adjusted odds ratios (aOR) with their respective 95% confidence interval (CI).SettingSierra Leone.ParticipantsA weighted sample of 1730 in-school adolescents in Sierra Leone.Outcome measureCurrent alcohol use.ResultsThe prevalence of alcohol use among in-school adolescents was 10.7% (7.3, 15.3). In-school adolescents in senior secondary schools were more likely to use alcohol compared with those in junior secondary school (aOR=2.13; 95% CI 1.37, 3.30). The odds of alcohol use was higher among in-school adolescents who were truant at school relative to those who were not (aOR=2.24; 95% CI 1.54, 3.26). Also, in-school adolescents who were bullied (aOR=1.85; 95% CI 1.24, 2.76), ever engaged in sexual intercourse (aOR=2.06; 95% CI 1.39, 3.06), and used marijuana (aOR=3.36; 95% CI 1.72, 6.53) were more likely to use alcohol compared with those who were not. However, in-school adolescents who reported that their parents understood their problems (aOR=0.52; 95% CI 0.33, 0.82) had a lower likelihood of consuming alcohol.ConclusionOur study has shown that alcohol use is prevalent among in-school adolescents in Sierra Leone. Grade level, experiences of being bullied, history of sexual intercourse, truancy at school, and previous use of marijuana were the factors influencing alcohol use among in-school adolescents. The findings emphasise the necessity of creating school-based health interventions in Sierra Leone that can effectively identify in-school adolescents potentially vulnerable to alcohol-related issues. Also, existing policies and programmes aimed at reducing alcohol use among in-school adolescents need to be strengthened.
