ABSTRACT
BACKGROUND: Demand for stroke rehabilitation is expected to grow dramatically; with the estimated prevalence of stroke survivors rising to 70 million worldwide by 2030. The World Health Organization's (WHO) report - Rehabilitation 2030: A call for action - has introduced the objective of 'upscaling' rehabilitation globally to meet demand. This research explored what upscaling stroke rehabilitation might mean for health professionals from countries at different stages of economic development. METHODS: Qualitative descriptive study design using semi-structured interviews was employed. Purposively sampled, clinical leaders in stroke rehabilitation were recruited for interviews from low through to high-income countries. RESULTS: Twelve rehabilitation professionals (medicine, physical therapy, occupational therapy, and speech and language therapy) from high (United States of America, Germany, United Kingdom, United Arab Emirates, New Zealand), upper-middle (Colombia and Turkey), lower-middle (Vietnam, Pakistan, Ghana), and low-income countries (Nepal and Sierra Leone) were interviewed. Upscaling was seen as a necessity. Successful scaling up will require initiatives addressing: political governance and managerial leadership, increasing knowledge and awareness of the value of rehabilitation, financial support, workforce developments, physical space and infrastructure, and the development of community services and reintegration. CONCLUSION: Although there have been many gains within the development of stroke rehabilitation internationally, further investment is required to ensure that this patient population group continues to receive the best quality services. For the WHO to be successful in implementing their objective to upscale rehabilitation, specific attention will need to be paid to political, professional, economic, and sociocultural issues at global and local levels.

BACKGROUND: Midwifery centres have been identified in over 56 countries. Consensus was reached on a global definition for midwifery centres, yet there is a lack of standards to assure consistent quality of care is provided. METHODS: Evidence-based standards and guidelines developed from American Association of Birth Centres (USA), Midwifery Unity Network (UK/EU), World Health Organization, International Childbirth Initiative, and White Ribbon Alliance, were gathered, duplicate standards were removed, and language was adapted for global use with sensitivity to low and middle countries (LMIC). An initial list of 52 midwifery centre standards were identified. Through an informal modified Delphi process these were reviewed by global midwifery centres experts, researchers, and midwifery centre staff at focus groups in Haiti, Mexico and Bangladesh for significance, language, and usability. The standards were then piloted at midwifery centres in eight countries (Sierra Leone, Cambodia, Bangladesh, Mexico, Haiti, Peru, Uganda and Trinidad). All feedback was incorporated into the final standards. RESULTS: A final list of 43 standards, organized into 3 domains including quality standards for care providers, dignity standards for women, and community standards for administration, were agreed on. CONCLUSION: Midwifery centres are prevalent around the globe. Identifying standards for quality of care provides a foundation for the midwifery centre model to be replicated and ensure consistent quality of care. Evidence based standards for midwifery centres in LMIC, allows systems to embrace and encourage the implementation and growth of midwifery centres to address accessible, acceptable, respectful, woman-centred, community-engaged maternal health care that participates fully in the health care system.

INTRODUCTION: Delays in arrival and treatment at health facilities lead to negative health outcomes. Individual and external factors could be associated with these delays. This study aimed to assess common factors associated with arrival and treatment delays in the emergency departments (ED) of three hospitals in humanitarian settings. METHODOLOGY: This was a cross-sectional study based on routine data collected from three MSF-supported hospitals in Afghanistan, Haiti and Sierra Leone. We calculated the proportion of consultations with delay in arrival (>24 hours) and in treatment (based on target time according to triage categories). We used a multinomial logistic regression model (MLR) to analyse the association between age, sex, hospital and diagnosis (trauma and non-trauma) with these delays. RESULTS: We included 95,025 consultations. Males represented 65.2%, Delay in arrival was present in 27.8% of cases and delay in treatment in 27.2%. The MLR showed higher risk of delay in arrival for females (OR 1.2, 95% CI 1.2-1.3), children <5 (OR 1.4, 95% CI 1.4-1.5), patients attending to Gondama (OR 30.0, 95% CI 25.6-35.3) and non-trauma cases (OR 4.7, 95% CI 4.4-4.8). A higher risk of delay in treatment was observed for females (OR 1.1, 95% CI 1.0-1.1), children <5 (OR 2.0, 95% CI 1.9-2.1), patients attending to Martissant (OR 14.6, 95% CI 13.9-15.4) and non-trauma cases (OR 1.6, 95% CI 1.5-1.7). CONCLUSIONS: Women, children <5 and non-trauma cases suffered most from delays. These delays could relate to educational and cultural barriers, and severity perception of the disease. Treatment delay could be due to insufficient resources with consequent overcrowding, and severity perception from medical staff for non-trauma patients. Extended community outreach, health promotion and support to community health workers could improve emergency care in humanitarian settings.

Introducción: La enfermedad del ébola se dio a conocer por primera vez en 1976, con una letalidad muy elevada en todos los brotes detectados. Objetivo: Caracterizar clínica y epidemiológicamente a los pacientes portadores de la enfermedad por el virus del Ébola. Métodos: Se realizó un estudio observacional, descriptivo y transversal en 424 pacientes ingresados en un centro de tratamiento de ébola en la República de Sierra Leona, África occidental, con el diagnóstico confirmado mediante la técnica de reacción en cadena de la polimerasa para virus Ébola, durante el período de noviembre de 2014 hasta marzo de 2015. Resultados: Se muestra que el grupo etario más afectado fue el de 25 a 34 con un 25,9 por ciento. La mayor letalidad se presentó en los pacientes con más de 65 años de edad con un 44,4 por ciento. El síntoma que prevaleció fue la fiebre para un 61,8 por ciento, y el hipo se presentó en el 88,8 por ciento de los fallecidos. Conclusión: Se concluye que la enfermedad no tuvo distinción significativa con el sexo. La mayor letalidad se presentó en las edades geriátricas. Los síntomas más frecuentes fueron la fiebre, diarrea y el decaimiento. El hipo fue el signo que más se presentó en los pacientes que fallecieron(AU)
Introduction: Ebola disease was first reported in 1976 with a very high lethality in all outbreaks. Objective: To clinically and epidemiologically characterize the patients carriers of Ebola virus disease. Methods: we conducted an observational, descriptive and cross-sectional study in 424 patients admitted to an Ebola Treatment Center in the Republic of Sierra Leone, West Africa from November 2014 to March 2015. The polymerase chain reaction technique for Ebola virus confirmed the diagnosis. Medical records provided all data. Results: The age group most affected was 25 to 34 (25.9 percent). The highest lethality occurred in those over 65 years of age (44.4 percent ). Fever was the prevailing symptom (61.8 percent) and hiccups occurred in 88.8 percent of the deceased. Conclusion: Clinical manifestations were variable, although fever was the main symptom. Hiccup was a sign of poor prognosis when associated with a higher percentage of mortality. Lethality was high(AU)

Substandard antibiotics are thought to be a major threat to public health in developing countries and a cause of antimicrobial resistance. However, assessing quality outside of a laboratory setting, using simple equipment, is challenging. The aim of this study was to validate the use of a portable Fourier transform infrared (FT-IR) spectrometer for the identification of substandard antibiotics. Results are presented for amoxicillin packages from Haiti, Ghana, Sierra Leone, Democratic Republic of Congo, India, Papua New Guinea, and Ethiopia collected over the course of 6 months in 2017, including two field trips with the FT-IR to Ghana and Sierra Leone. Canadian samples were used as a control. Regarding drug quality, of 290 individual capsules of amoxicillin analyzed, 13 were found to be substandard with total active pharmaceutical ingredients (API) lying outside the acceptable range of 90-110%. Of these 13, four were below 80% API. The FT-IR reliably identified these outliers and was found to yield results in good agreement with the established pharmacopeia liquid chromatography protocol. We conclude that the portable FT-IR may be suitable to intercept substandard antibiotics in developing countries where more sophisticated techniques are not readily available.

Rhabdomyolysis results from acute necrosis of skeletal muscle fibres and consequent leakage of muscle constituents into the circulation. Its association with anything different than trauma in the Emergency Room is not that frequent. We present the case of a 47-year-old male, hypertensive, that developed weakness and incapability to walk without help, finding on the blood biochemistry that he had developed a rhabdomyolysis due to hipokalemia after abusing of diuretics.
La rabdomiólisis es el resultado de la necrosis de las fibras musculoesqueléticas y la consiguiente fuga de constituyentes musculares a la circulación. Su asociación con algo diferente a un trauma en la sala de emergencias no es tan frecuente. Presentamos el caso de un varón de 47 años, hipertenso, con historia de abuso de diuréticos, desarrollando debilidad e incapacidad para caminar por sus propios medios, encontrando en la bioquímica sanguínea que había padecía rabdomiólisis por hipocalemia.

Introduction: Fetal hemoglobin is an important factor in modulating the severity of sickle cell anemia. Its level in peripheral blood underlies strong genetic determination. Associated loci with increased levels of fetal hemoglobin display population-specific allele frequencies. Objective: We investigated the presence and effect of known common genetic variants promoting fetal hemoglobin persistence (rs11886868, rs9399137, rs4895441, and rs7482144) in 60 Colombian patients with sickle cell anemia. Materials and methods: Four single nucleotide polymorphisms (SNP) were genotyped by restriction fragment length polymorphisms (RFLP) and the use of the TaqMan procedure. Fetal hemoglobin (HbF) from these patients was quantified using the oxyhemoglobin alkaline denaturation technique. Genotype frequencies were compared with frequencies reported in global reference populations. Results: We detected genetic variants in the four SNPs, reported to be associated with higher HbF levels for all four SNPs in the Colombian patients. Genetic association between SNPs and HbF levels did not reach statistical significance. The frequency of these variants reflected the specific ethnic make-up of our patient population: A high prevalence of rs7482144-'A' reflects the West-African origin of the sickle cell mutation, while high frequencies of rs4895441-'G' and rs11886868-'C' point to a significant influence of an Amerindian ethnic background in the Colombian sickle cell disease population. Conclusion: These results showed that in the sickle cell disease population in Colombia there is not a unique genetic background, but two (African and Amerindian). This unique genetic situation will provide opportunities for a further study of these loci, such as fine-mapping and molecular-biological investigation. Colombian patients are expected to yield a distinctive insight into the effect of modifier loci in sickle cell disease.
Introducción. La hemoglobina fetal es un importante factor modulador de la gravedad de la anemia falciforme, cuya expresión está muy condicionada por el factor genético. Los loci asociados con el incremento de la hemoglobina fetal pueden presentar frecuencias alélicas específicas para cada población. Objetivo. Investigar la presencia y el efecto de las variantes genéticas rs11886868, rs9399137, rs4895441 y rs7482144 asociadas con la persistencia de hemoglobina fetal, en 60 pacientes colombianos con anemia falciforme. Materiales y métodos. Se hizo la genotipificación de los polimorfismos de nucleótido simple ( Single Nucleotide Polymorphisms, SNP) mediante la técnica de polimorfismos de longitud de fragmentos de restricción ( Restriction Fragment Length Polymorphisms, RFLP) y el procedimiento TaqMan. La hemoglobina fetal (HbF) se cuantificó utilizando la técnica de desnaturalización alcalina de la oxihemoglobina. Las frecuencias genotípicas se compararon con las reportadas en poblaciones de referencia global. Resultados. Se observaron variantes genéticas ya reportadas para aumento de HbF en los cuatro SNP. La asociación genética entre los SNP y el incremento de la HbF no alcanzó significancia estadística. La frecuencia de estos alelos reflejó la siguiente composición específica en esta muestra de pacientes colombianos: una gran prevalencia de rs7482144-'A', lo que indica que el origen de la mutación para la anemia falciforme es África occidental, y una gran frecuencia de rs4895441-'G' y rs11886868-'C', lo que denota la influencia significativa del origen genético amerindio. Conclusión. Los resultados evidenciaron que la población con anemia falciforme de Colombia no tiene un único origen genético, sino que existen dos (africano y amerindio). Esta situación genética única ofrece la oportunidad de llevar a cabo un estudio más amplio de estos loci a nivel molecular. Se espera que el estudio de pacientes colombianos permita una visión diferente del efecto de los loci modificadores en esta enfermedad.

BACKGROUND: In light of the decline in donor HIV funding, HIV programmes increasingly need to assess their available and potential resources and maximize their utilization. This article presents lessons learned related to how countries have addressed the sustainability of HIV programmes in a stakeholder-driven sustainability analysis. METHODOLOGY: During HIV/AIDS Programme Sustainability Analysis Tool (HAPSAT) applications in six countries (Benin, Guyana, Kenya, Lesotho, Sierra Leone and South Sudan), stakeholders identified key sustainability challenges for their HIV responses. Possible policy approaches were prepared, and those related to prioritization and resource mobilization are analysed in this article. RESULTS: The need to prioritize evidence-based interventions and apply efficiency measures is being accepted by countries. Five of the six countries in this study requested that the HAPSAT team prepare 'prioritization' strategies. Countries recognize the need to prepare for an alternative to 'universal access by 2015', acknowledging that their capacity might be insufficient to reach such high-coverage levels by then. There is further acceptance of the importance of reaching the most-at-risk, marginalized populations, as seen, for example, in South Sudan and Sierra Leone. However, the pace at which resources are shifting towards these populations is slow. Finally, only two of the six countries, Kenya and Benin, chose to examine options for generating additional financial resources beyond donor funding. In Kenya, three non-donor sources were recommended, yet even if all were to be implemented, it would cover only 25% of the funding needed. CONCLUSIONS: Countries are increasingly willing to address the challenges of HIV programme sustainability, yet in different ways and with varying urgency. To secure achievements made to date and maximize future impact, countries would benefit from strengthening their strategic plans, operational plans and funding proposals with concrete timelines and responsibilities for addressing sustainability issues.

This study investigated the trends in tuberculosis mortality through time in Switzerland. Information on the decline in mortality before chemotherapies were introduced may be useful in developing countries where drug-resistant tuberculosis is now becoming a major problem. Swiss data were collected from historical records and comparative data were obtained from the literature for England and Wales, New York, Japan, Brazil and Sierra Leone. Logistic curves were fitted to examine the rate of decline before introduction of pharmacotherapies and these show that the decline would have continued without the introduction of chemical therapies, including antibiotics. In Switzerland, England and Wales and New York, the decline had occurred long before the introduction of specific anti-tuberculosis agents. In Brazil and Japan, chemical therapy was co-incident with the decline in tuberculosis mortality rates. Overall, it is suggested that the effective control of tuberculosis can be achieved through a combination of chemical interventions, conservative therapy (rest, good nutrition, ventilation, etc.) as well as public health interventions addressing hygiene, nutrition, reducing exposure to infections and educating the population about tuberculosis.

Opioid analgesics are simultaneously indispensable medicines for the treatment of moderate to severe pain and are harmful when abused. The challenge for governments is to balance the obligation to prevent diversion, trafficking, and abuse of opioids with the equally important obligation to ensure their availability and accessibility for the relief of pain and suffering. Over the last 30 years, significant progress has been made toward improving access to opioids as measured by increasing global medical opioid consumption. However, this progress is marked by ongoing large disparities among countries, with most increases in medical opioid consumption attributed to high-income countries, not low- and middle-income countries (LMICs). The International Pain Policy Fellowship (IPPF) was developed by the Pain & Policy Studies Group, with the central goal of developing national leaders from LMICs and empowering them to improve availability and accessibility of opioids for the treatment of pain. To date, two classes of fellows have been selected, representing 17 fellows from 15 countries. Progress achieved by the leadership of three fellows from Sierra Leone, Colombia, and Serbia is highlighted in this paper. The fellows from each country were successful at initiating collaboration with relevant governmental bodies, national authorities, and professional societies, which resulted in a new supply of oral opioids in Sierra Leone and Serbia, and improvements in the distribution of already available opioids in Colombia. All fellows were instrumental in facilitating evaluation of national policy. The IPPF program empowers fellows with the necessary knowledge, skills, and guidance to improve the availability and accessibility of opioids for the treatment of pain.

One of the mandates of Statistics Sierra Leone (SSL) is to collect, collate, process, analyse, publish and disseminate population census and survey data at all levels. Statistics Sierra Leone has the additional mandate of being the focal point for policy formulation and coordination of population activities in the country. By this mandate, Statistics Sierra Leone occupies the leadership position in the population sector and the major provider of information on the Sierra Leone population. The successful conduct of the 2008 Sierra Leone Demographic and Health Survey (SLDHS) and the production of this report, within a reasonably short time frame, undoubtedly underscores Statistics Sierra Leones leadership role. The compilation of the report has been borne out of the need to meet the yearnings of policy makers, programme implementers, and researchers, who require timely data for their day-to-day operations. The report contains detailed information on the demographic, health, and social indicators that will enable us measure progress in the Sierra Leone Society

This paper reports on research conducted on the insecurity of non-governmental organisations (NGOs) between 1999 and 2002, with the goal of contributing to the debate on the reasons why NGO actors are targets of violence in conflict settings. The research involved the collection of data from three countries-Angola, Ecuador and Sierra Leone-and exploration of the relationship between levels of insecurity, context and the characteristics of NGOs. Four risk factors appear to heighten the degree of insecurity that NGOs face: (1) carrying out multiple types of activities and providing material aid; (2)'operationality'(that is, implementing programmes and activities); (3) working with both sides of the conflict; and (4) integrating into the local community. The paper discusses the methodological approach adopted for the research, the differences between ambient and situational insecurity and the findings related to risk factors. It concludes with a summary of the study's implications.

To better understand the population substructure of African Americans living in coastal South Carolina, we used restriction site polymorphisms and an insertion/deletion in mitochondrial DNA (mtDNA) to construct seven-position haplotypes across 1,395 individuals from Sierra Leone, Africa, from U.S. European Americans, and from the New World African-derived populations of Jamaica, Gullah-speaking African Americans of the South Carolina Sea Islands (Gullahs), African Americans living in Charleston, South Carolina, and West Coast African Americans. Analyses showed a high degree of similarity within the New World African-derived populations, where haplotype frequencies and diversities were similar. Phi-statistics indicated that very little genetic differentiation has occurred within New World African-derived populations, but that there has been significant differentiation of these populations from Sierra Leoneans. Genetic distance estimates indicated a close relationship of Gullahs and Jamaicans with Sierra Leoneans, while African Americans living in Charleston and the West Coast were progressively more distantly related to the Sierra Leoneans. We observed low maternal European American admixture in the Jamaican and Gullah samples (m = 0.020 and 0.064, respectively) that increased sharply in a clinal pattern from Charleston African Americans to West Coast African Americans (m = 0.099 and 0.205, respectively). The appreciably reduced maternal European American admixture noted in the Gullah indicates that the Gullah may be uniquely situated to allow genetic epidemiology studies of complex diseases in African Americans with low European American admixture.

AIM: To report the presence of Behçet's disease with ocular involvement in patients of west African or Afro-Caribbean origin. METHODS: Case series of eight patients reporting to a tertiary uveitis service. RESULTS: Eight patients with typical features of the disease are presented. Six of the eight patients were tested and found to be HLA-B51 negative. CONCLUSION: Behçet's disease has only been reported in sporadic case reports in the indigenous west African and Afro-Caribbean populations, in whom the incidence of HLA B51 is also very low. A series of patients from the London region presented with the typical symptoms and signs of disease, most of whom were also HLA B51 negative. The presence of disease in this population, when absent in the indigenous population, suggests either that ascertainment of disease is poor in the indigenous population or that acquired factors may be important in the aetiology of the disease.

This article reports the results of a Saint Lucia survey, part of a larger program, that was the first to document the prevalence of suboptimal safety practices among vector control and farm workers using pesticides in the English-speaking Caribbean. Among other things, the survey found that many of 130 pesticide users surveyed were unaware that the skin and eyes were important potential routes of absorption. Over a quarter said had felt ill at some point as a result of pesticide use. About half the respondents said they had received more than "introductory" training in safe pesticide use, and most said they always found labels or directions affixed to pesticide containers. However, about half said they never or only sometimes understood the labels, and many of those who said they understood did not always follow the instructions. About a quarter of the smokers said they smoked while using pesticides; about a sixth of the survey subjects said they ate food while using pesticides; and over 60 percent said they never wore protective clothing
