RESUMEN

INTRODUCTION: Despite the early implementation of hepatitis B vaccination and the ongoing decentralisation of chronic hepatitis B (CHB) care, over 10% of the Senegalese adult population lives with CHB and liver cancer remains a main cause of death. Investigating factors associated with CHB infection, prevention of CHB-related morbidity, and prevention and treatment of mortality secondary to CHB calls for a holistic and multidimensional approach. This paper presents the adaptation of the health capability profile (HCP) to a specific epidemiological issue and empirical setting: it seeks to identify and analyse inter-related abilities and conditions (health capabilities) in relation to the CHB epidemic in the rural area of Niakhar, Senegal. METHODS AND ANALYSIS: This ongoing study relies on a sequential social justice mixed-methods design. The HCP is comprehensively adapted to CHB in rural Senegal and guides the design and conduct of the study. Objective and subjective data are collected at the individual level following a mixed-methods explanatory core design. The quantitative module, embedded in the ANRS12356 AmBASS cross-sectional survey (exhaustive sampling), is used to select a purposeful sampling of participants invited for one-on-one qualitative interviews. Additional data are collected at the institutional and community level through health facility surveys and an ethnography (in-depth interviews) of local and national CHB stakeholders. Data analysis adopts a synergistic approach to produce a multilayered analysis of individual HCPs and crosscutting analysis of the 15 health capabilities. The data integration strategy relies on a mixed-methods convergent core design, and will use 0-100 health capability scores as well as flow diagrams to measure and characterise levels of development and interactions among health capabilities, respectively. ETHICS AND DISSEMINATION: This study was approved by Senegalese and French authorities. Results dissemination through local workshops and scientific publications aim at fuelling effective policy change towards CHB-related health capability.

RESUMEN

To assess the coverage rate of routine vitamin A supplementa tion, a descriptive study was carried out in the Guédiawaye Health District. The coverage rate for vitamin A supplementation was 48.6%. Age over 24 months, uneducated father, maternal age over 25, and lack of disease-related knowledge were factors associated with delayed vitamin A supplementation.

RESUMEN

BACKGROUND: Ready-to-use food (RUF) is increasingly used for nutritional therapy in HIV-infected individuals. However, practical guidance advising nutrition care to HIV-infected adolescents is lacking, so that little is known about the acceptability of such therapy in this vulnerable population. This study assesses the overall acceptability and perception of a RUF-based therapy and risk factors associated with sub-optimal RUF intake in HIV-infected undernourished adolescents in Senegal. METHODS: Participants 5 to 18 years of age with acute malnutrition were enrolled in 12 HIV clinics in Senegal. Participants were provided with imported RUF, according to WHO prescription weight- and age-bands (2009), until recovery or for a maximum of 9-12 months. Malnutrition and recovery were defined according to WHO growth standards. Adherence was assessed fortnightly by self-reported RUF intake over the period. Sub-optimal RUF intake was defined as when consumption of the RUF provision was < 50%. RUF therapy acceptability and perceptions were assessed using a structured questionnaire at week 2 and focus group discussions (FGDs) at the end of the study. Factors associated with sub-optimal RUF intake at week 2 were identified using a stepwise logistic regression model. RESULTS: We enrolled 173 participants, with a median age of 12.5 years (Interquartile range: 9.5-14.9), of whom 61% recovered from malnutrition within the study period. Median follow-up duration was 66 days (21-224). RUF consumption was stable, varying between 64 and 57% of the RUF provided, throughout the follow-up. At week 2, sub-optimal RUF intake was observed in 31% of participants. Dislike of the taste of RUF (aOR = 5.0, 95% CI: 2.0-12.3), HIV non-disclosure (5.1, 1.9-13.9) and food insecurity (2.8, 1.1-7.2) were the major risk factors associated with sub-optimal RUF intake at week 2. FGDs showed that the need to hide from others to avoid sharing and undesirable effects were other constraints on RUF feeding. CONCLUSIONS: This study revealed several factors reducing the acceptability and adherence to RUF therapy based on WHO guidelines in HIV-infected adolescents. Tailoring prescription guidance and empowering young patients in their care are crucial levers for improving the acceptability of RUF-based therapy in routine care. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT03101852, 04/04/2017.

RESUMEN

Mycetoma is a neglected tropical disease caused by various actinomycetes or fungi. The disease is characterized by the formation of tumor like-swellings and grains. Senegal is an endemic country where mycetoma cases are under-or misdiagnosed due to the lack of capacities and knowledge among health workers and the community; and where the management of eumycetoma, burdened by a high amputation rate, is currently inadequate. This study aimed to update data on the epidemiology of mycetoma cases diagnosed in three hospital centres in Senegal over a 10 years-period. A total of 193 patients, diagnosed from 2008 to 2018, were included in the study. The most frequent presentation was eumycetoma (47.2%); followed by actinomycetoma (36.8%); it remained undetermined in 16.1% of the patients. The mean age was 38.3 years (68.4% of the patients were between 15 and 45 years-old); the male: female ratio was a 2.94; and most were farmers. One hundred fifty-six (80.8%) patients had used phytotherapy before attending the hospital. Mycetoma was mainly located to the lower limbs (91.2%). Grains were observed in 85% of the patients; including white (25.6%) and yellow (4.3%) grains. The etiological diagnosis was complex, resulting in negative direct microscopy, culture and/or histopathology findings, which explains that 16.1% remained uncharacterized. In most of cases, actinomycetoma were treated with a combination of cotrimoxazole, amoxicillin/clavulanic acid, and streptomycin; whereas eumycetoma cases were treated with terbinafine. The surgery was done in 100 (51.8%) of the patients including 9 in actinomycetoma, 78 in eumycetoma and 13 in undetermined form. The high number of uncharacterized mycetoma in this study, the delay in attending a qualified health-care facility, and the lack of available adequate antifungal drug, point out the need to strengthen mycetoma management capacities in Senegal.

RESUMEN

INTRODUCTION: Rape remains one of the most serious forms of sexual violence because of its negative impact on the physical and mental health of victims. The objective of this study is to identify the factors associated with the delay in rape victims seeking medical assistance from healthcare professionals in Senegal. METHODOLOGY: A retrospective, descriptive and analytical observation study was conducted. The study population consisted of all the court files of girls or women victims of rape recorded by the investigators at the 11 high courts of Senegal during the period from 2006 to 2015. An exhaustive recruitment of the full records of rape victims meeting the inclusion criteria were completed. The uni and multivariate analyses were carried out with Epi Info 2000 and R 2.2.9 software respectively. RESULTS: At the end of the collection, 1,037 cases of rape were included in the study population. The average age of the victims was 16.3±7.9 years (range 1-72). Minors (<18 years) accounted for 24.8 %. The median time from rape to consultation at a health facility was 24hours. Long delay in consultation (>24hours) was noted for 38.6 % of victims. Risk of late consultation after rape was higher among victims residing in the southern areas (ORaj=4.31 [1.15-16.14]), or northern areas (ORaj=4.22 [1.26-14.14]), who were major (ORaj=1.67 [1.04-2.68]) or married (ORaj=3.44 [1.58-7.5]) or who were pregnant after the aggression (ORaj=34.03 [15.47-74.85]) or had an abortion (ORaj=5.45 [1.04-24.47]). CONCLUSION: Medical and judicial assistance are more difficult if there is a long delay between the aggression and consultation. Thus, it is important for the health and judicial authorities to raise awareness about the harmful consequences of sexual violence, and to put forward the benefits of therapeutic care, compensation for the harm suffered by rape victims, as well as the availability of holistic care services 24hours a day.

RESUMEN

OBJECTIVES: The goals of this study were to determine the frequency of traditional healer use among people living with HIV in Senegal, to identify predictors of traditional healer use, and to determine if traditional healer use is associated with HIV outcomes. DESIGN: Prospective longitudinal study. METHODS: Participants were enrolled from April 2017 to April 2018 in Dakar and Ziguinchor, Senegal. Interviews, clinical evaluations, laboratory analyses, and chart review were conducted. Logistic regression was used to identify sociodemographic predictors of traditional healer use and to determine the associations between HIV-outcomes and use of a traditional healer. Survival analysis was conducted using the Kaplan-Meier method. RESULTS: Data from 157 HIV-positive individuals were included; 34% reported seeking care from a traditional healer. Median follow-up was 224 days (interquartile range 118-339.5). Predictors of traditional healer use included age greater than or equal to 35 years and residence in the Casamance region. HIV-1-infected participants who sought care from a traditional healer had lower baseline CD4 cell counts compared with those who did not (104 versus 208; P = 0.02), and a greater percentage presented with advanced disease (85% versus 62%; P = 0.01). A greater percentage of those who sought care from a traditional healer died (13.2 versus 2.9%; P = 0.03). HIV-1-infected individuals with advanced disease [odds ratio (OR) 3.58, 95% confidence interval (CI) 1.18-10.82], those who were malnourished (OR 3.79, 95% CI 1.63-8.83), and those who died during follow-up (OR 7.26, 95% CI 1.34-39.37) were more likely to have sought care from a traditional healer. CONCLUSION: Traditional healer use is common among people living with HIV in Senegal and is associated with advanced disease and increased mortality. Partnering with traditional healers may be an effective strategy to improve the HIV care cascade and decrease mortality in the region.

RESUMEN

BACKGROUND: The WHO guidelines for the management of advanced HIV disease recommend a package of care consisting of rapid initiation of antiretroviral therapy (ART), enhanced screening and diagnosis of tuberculosis (TB) and cryptococcal meningitis, co-trimoxazole prophylaxis, isoniazid preventive therapy (IPT), fluconazole pre-emptive therapy, and adherence support. The goals of this study were to determine the prevalence of advanced HIV disease among individuals initiating ART in Senegal, to identify predictors of advanced disease, and to evaluate adherence to the WHO guidelines. METHODS: This study was conducted among HIV-positive individuals initiating ART in Dakar and Ziguinchor, Senegal. Clinical evaluations, laboratory analyses, questionnaires and chart review were conducted. Logistic regression was used to identify predictors of advanced disease. RESULTS: A total of 198 subjects were enrolled; 70% were female. The majority of subjects (71%) had advanced HIV disease, defined by the WHO as a CD4 count < 200 cells/mm3 or clinical stage 3 or 4. The median CD4 count was 185 cells/mm3. The strongest predictors of advanced disease were age ≥ 35 (OR 5.80, 95%CI 2.35-14.30) and having sought care from a traditional healer (OR 3.86, 95%CI 1.17-12.78). Approximately one third of subjects initiated ART within 7 days of diagnosis. Co-trimoxazole prophylaxis was provided to 65% of subjects with CD4 counts ≤350 cells/mm3 or stage 3 or 4 disease. TB symptom screening was available for 166 subjects; 54% reported TB symptoms. Among those with TB symptoms, 39% underwent diagnostic evaluation. Among those eligible for IPT, one subject received isoniazid. No subjects underwent CrAg screening or received fluconazole to prevent cryptococcal meningitis. CONCLUSIONS: This is the first study to report an association between seeking care from a traditional healer and presentation with WHO defined advanced disease in sub-Saharan Africa. Given the widespread use of traditional healers in sub-Saharan Africa, future studies to further explore this finding are indicated. Although the majority of individuals in this study presented with advanced disease and warranted management according to WHO guidelines, there were numerous missed opportunities to prevent HIV-associated morbidity and mortality. Programmatic evaluation is needed to identify barriers to implementation of the WHO guidelines and enhanced funding for operational research is indicated.

RESUMEN

OBJECTIVE: To determine the epidemiological and etiological profile of tinea capitis in adults in Dakar (Senegal). PATIENTS AND METHODS: A 9-month prospective, multicenter, descriptive and analytic study. Patients included were aged over 18 years. Mycological tests were used to confirm the diagnosis. RESULTS: 121 patients were included with a mean age of 36.1 years and a hospitalisation frequency of 0.8%. The age range of 64.4% of patients was between19 and 38 years. 51% of patients were housewives. A low socioeconomic level was found in 72.8% of cases. In 3.3% of patients, the disease began in childhood. 31.4% of patients had already consulted a traditional healer. Similar familial cases were noted in 60.3% of patients. Contact with a sheep was noted in 32.2% of cases, deliberate skin lightening in 64% of women, hair salon attendance in 46.7% of women, and immunosuppression in 17.3% of patients, while itching was present in 95.5%. Dermatologic examination showed scaled plaques and a diffuse form, with 92.6% and 64% (n=75) respectively. Wood's light examination was positive in 40.2% of patients. A positive culture test was found in 71%. The most frequently encountered species were: T. soudanense (65%), M. audouinii (21%), T. rubrum (4.7%), M. gypseum (3.5%), T. violaceum (2.3%), T. verrucosum (2.3%) and M. canis (1 case). The clinical course was favorable under treatment with griseofulvin or terbinafine. CONCLUSION: Tinea capitis in adults mainly affects young women. The diffuse form is the most common. The most frequently encountered species was T. soudanense.

RESUMEN

BACKGROUND: Cervical cancer is the second most common women's cancer in less developed regions and it is the leading cause of cancer mortality among women in Senegal. Because of the high costs, cervical cancer prevention is very rare in developing countries and it is often based on visual inspection methods. The University of Parma (CUCI)  and the MANI association have developed a cervical cancer screening project addressed to rural Senegal communities. The aim of the project was to disseminate the cytocervical sampling technique among Senegalese nurses and midwives, as a completion to the local visual inspection method. Other objectives were to verify the prevalence of precancerous lesions and to evaluate cervical cancer knowledge and attitudes among women who participated at the screening campaign. INTERVENTIONS: A theoretical and practical training plan on cervical cancer screening was provided to the local health workers at various levels. The screening was performed through a first step visual inspection exam to 203 women, followed by a Pap smear in case of positive outcome. 20 women participated also to a structured interview. RESULTS: The Pap smear material was adequate in all the samples collected where this indicates that the objective to disseminate cervical cancer screening techniques has been achieved.  Of the 203 women involved in the screening project, 68 were tested positive at the first step and 38 of them were submitted to Pap tests. CONCLUSION: The difficulties encountered confirm how Pap tests have overall proved inordinately complex and expensive for developing countries. It seems more sensible to deal first with global health in terms of basic hygienic sanitation, including an educational component in screening programs in order to sensitize women to the risk factors of cervical cancer.

RESUMEN

INTRODUCTION: The long diagnostic delay is responsible for the extension of radiological lesions and spread of TB in the community. These radiological lesions can leave significant scars responsible for respiratory disability. OBJECTIVE: The aim of the study is to characterize radiologic features according to tuberculosis diagnostic delay. METHODS: We conducted a prospective cross-sectional study, about 66 patients with positive sputum. RESULTS: The average diagnostic delay was 16 (±15) weeks; whether 22 (±14.1) weeks in the female gender versus 14.6 (±14.3) weeks in the male gender (P=0.10). The first care use was respectively health centers (62.1%), drugstores (51.9%), and traditional medicine (28.7%). Only 27.2% of patients used the marabouts care. Bilateral radiographic abnormalities in bivariate analysis were associated with consultation at the health center (66.7% versus 33.3%; P<0.031), as is the extension of the lesions (70.2% versus 29.8% RP=1.66 [1.05 to 2.91]; P<0.03). Lake of knowledge of the symptoms of TB was associated with the use of marabouts care (12.5% versus 87.5; PR=0.35 [0.11 to 1.08], P<0.04). CONCLUSION: These results should prompt consideration in an emergency, appropriate control interventions, advocacy, patient information and medical personnel on the reality of tuberculosis to prevent its spread often causing respiratory disability with radological effects.

RESUMEN

Malaria is endemic in Senegal. The national malaria control strategy focuses on achieving universal coverage for major interventions, with a goal of reaching preelimination status by 2018. Senegal began distribution of insecticide-treated nets (ITNs) and introduced artemisinin-based combination therapy in 2006, then introduced rapid diagnostic tests in 2007. We evaluated the impact of these efforts using a plausibility design based on malaria's contribution to all-cause under-five mortality (ACCM) and considering other contextual factors which may influence ACCM. Between 2005 and 2010, household ownership of ITNs increased from 20% to 63%, and the proportion of people sleeping under an ITN the night prior to the survey increased from 6% to 29%. Malaria parasite prevalence declined from 6% to 3% from 2008 to 2010 among children under five. Some nonmalaria indicators of child health improved, for example, increase of complete vaccination coverage from 58% to 64%; however, nutritional indicators deteriorated, with an increase in stunting from 16% to 26%. Although economic indicators improved, environmental conditions favored an increase in malaria transmission. ACCM decreased 40% between 2005 and 2010, from 121 (95% confidence interval [CI] 113-129) to 72 (95% CI 66-77) per 1,000, and declines were greater among age groups, epidemiologic zones, and wealth quintiles most at risk for malaria. After considering coverage of malaria interventions, trends in malaria morbidity, effects of contextual factors, and trends in ACCM, it is plausible that malaria control interventions contributed to a reduction in malaria mortality and to the impressive gains in child survival in Senegal.

RESUMEN

Infectious diseases represent one of the greatest potential barriers to achievement of the third Sustainable Development Goals in African countries and around the world because they continue to pose major public health challenges. The surveillance of infectious diseases has recently assumed greater importance in most African countries, both because of the emergence of infectious diseases and because strains of pathogens that cause tuberculosis, malaria, cholera, dysentery, and pneumonia have developed resistance to common and inexpensive antimicrobial drugs. However, data on the pathogen-specific causes of infectious diseases are limited. Developing research in infectious and tropical diseases in Africa is urgently needed to better describe the distribution of pathogen-borne diseases and to know which pathogens actually cause fever. This research is critical for guiding treatment and policies in Africa. More effective diagnostics are also needed for these diseases, which often are misdiagnosed or diagnosed too late. A comprehensive review of this type of research is presented here.

RESUMEN

OBJECTIVES: To describe prevalence and risk factors for wasting and stunting among HIV-infected children with a median duration of 3 years of antiretroviral therapy (ART) at the time of their enrollment in the cohort study. METHODS: Wasting and stunting at ART initiation and enrollment were defined as weight-for-height/body mass index-for-age Z scores < -2 and height-for-age Z scores < -2, respectively. Logistic regression was used to assess risk factors for wasting and stunting. Main predictive factors were age at enrollment, nutritional status and age (< or ≥5 years) at ART initiation and ART duration (< or ≥3 years on first-line, or ≥3 years including a switch to second-line ART). RESULTS: Two hundred forty-four children 2-16 years of age were enrolled. Overall, wasting and stunting prevalence dropped off consistently in children 2-10 years of age, between ART initiation and enrollment, while it remained at high levels, 52% and 42%, respectively, in children 10-16 years of age. Risk factors for wasting at enrollment were ART duration of ≥3 years including a switch to second-line [adjusted odds ratio (aOR): 3.9, 95% confidence interval (CI): 1.7-8.9] and wasting at ART initiation (aOR: 2.7, 95% CI: 1.4-5.2). The risk factor for stunting at enrollment was stunting at ART initiation (aOR: 11.6, 95% CI: 5.4-25.0), independent of ART duration. CONCLUSIONS: Malnutrition at the time of ART initiation was the main predictor of malnutrition at enrollment among HIV-infected children on ART. Longer duration on ART had no overall protective effect on wasting and stunting. Growth and virologic monitoring are of utmost importance in the comprehensive care of children with HIV infection.

RESUMEN

INTRODUCTION: Many countries have developed disease surveillance systems to deal with epidemics, but although health information systems have existed for more than two decades, constraints and biases in data collection limit the relevance of policy decisions and strategies in the field of health, as priority has been given to education and health in developing countries. Donor support has led to the development of systems for the production of statistics, designed, among other things, to more clearly target interventions in terms of educational objectives, action and credibility and enable health systems to continue to benefit from external funding. METHODS: We used a classical anthropology approach based on observations and in-depth interviews with local and national health system actors. RESULTS: The aim of this article is to analyse the real effects of the production of health statistics in health care systems and to determine the relevance of these figures in the context in which they apply. DISCUSSIONS: Health priorities defined by international organizations and technical and financial partners focus on diseases considered to be ?priorities? to the detriment of neglected diseases, which are perceived as being more important at the local level due to their impact on the already limited health systems.

RESUMEN

BACKGROUND: Prisoners represent a vulnerable population for blood-borne and sexually transmitted infections which can potentially lead to liver fibrosis and ultimately cirrhosis. However, little is known about the prevalence of liver fibrosis and associated risk factors among inmates in sub-Saharan Africa. METHODS: Screening of liver fibrosis was undertaken in a randomly selected sample of male inmates incarcerated in Lome, Togo and in Dakar, Senegal using transient elastography. A liver stiffness measurement ≥9.5 KPa was retained to define the presence of a severe liver fibrosis. All included inmates were also screened for HIV, Hepatitis B Virus (HBV) and Hepatitis C Virus (HCV) infection. Substances abuse including alcohol, tobacco and cannabis use were assessed during face-to-face interviews. Odds Ratio (OR) estimates were computed with their 95 % Confidence Interval (CI) to identify factors associated with severe liver fibrosis. RESULTS: Overall, 680 inmates were included with a median age of 30 years [interquartile range: 24-35]. The prevalence of severe fibrosis was 3.1 % (4.9 % in Lome and 1.2 % in Dakar). Infections with HIV, HBV and HCV were identified in 2.6 %, 12.5 % and 0.5 % of inmates, respectively. Factors associated with a severe liver fibrosis were HIV infection (OR = 7.6; CI 1.8-32.1), HBV infection (OR = 4.8; CI 1.8-12.8), HCV infection (OR = 52.6; CI 4.1-673.8), use of traditional medicines (OR = 3.7; CI 1.4-10.1) and being incarcerated in Lome (OR = 3.3; CI 1.1-9.8) compared to Dakar. CONCLUSIONS: HIV infection and viral hepatitis infections were identified as important and independent determinants of severe liver fibrosis. While access to active antiviral therapies against HIV and viral hepatitis expands in Africa, adapted strategies for the monitoring of liver disease need to be explored, especially in vulnerable populations such as inmates.

RESUMEN

BACKGROUND: In Africa, studies primarily devoted to chronic leg ulcer due to sickle cell disease are rare. The objectives of the study were to determine the epidemiology, diagnosis and progression of chronic leg ulcers in sickle cell disease. PATIENTS AND METHODS: A 5-year multicentre, retrospective study was conducted in three university hospitals in Dakar. We included all patients with chronic leg ulcers occurring in a setting of sickle cell disease. RESULTS: We identified 40 cases of chronic leg ulcers associated with sickle cell disease, representing 3.4% of the current population of sickle cell patients in our institutions. The average patient age was 25.9 years and the sex ratio was 2.33. Chronic leg ulcer was the presenting feature enabling diagnosis of sickle cell disease in one third of the cases. The average time to consultation from onset was 5.4 years. Pain was reported in 22 cases (48%). Ulcers were isolated in 76% and multiple in 24% of cases. The most common site was the medial malleolus (39%). A CBC allowed identification of anaemia in 35 cases. Haemoglobin electrophoresis was performed and homozygous sickle cell SS disease was identified in 39 cases and heterozygous SC disease in 1 case. Local treatments included physiologic serum, topical antibiotics and skin grafting. Systemic treatment included supplementation with folic acid in all patients, blood transfusion in 16 cases, vasodilators in 11 cases and antibiotics in 25 cases. The outcome was favourable in 61.8% of cases. DISCUSSION: In Dakar, sickle cell disease is a common cause of chronic leg ulcer and is frequently revealed by chronic leg ulcer.

RESUMEN

BACKGROUND: Food insecurity in sub-Saharan Africa and malnutrition constitute the main obstacles for successful treatment of people living with HIV/AIDS (PLWH). The aim of this study was to assess the effect of consuming daily 100 g RUTF (ready-to-use therapeutic food) as supplement, on body composition, anemia and zinc status of hospitalized PLWH in Senegal. METHODS: A Controlled clinical trial was conducted in 65 PLWH randomly allocated to receive either standard hospital diet alone (Control group: n = 33), or the standard diet supplemented with 100 g RUTF/day (RUTF group: n = 32). Supplementation was continued at home during 9 weeks. Individual dietary intakes were measured and compared to the Recommended Dietary Allowances. Body composition was determined using Bio-Impedance Analysis. Hemoglobin was measured by HemoCue and plasma zinc (PZ) concentration by atomic absorption spectrometry. PZ was adjusted to infection (CRP and α1-AGP). All measures were conducted on admission, discharge and after 9 weeks home-based follow up. RESULTS: 34 and 24% of the patients in RUTF and Control groups were suffering from severe malnutrition (BMI < 16 kg/m(2)), respectively. In both groups, more than 90% were anemic and zinc deficiency affected over 50% of the patients. Food consumed by the Control group represented 75, 14 and 55% of their daily recommended intake (DRI) of energy, iron and zinc, respectively. When 100 g of RUTF was consumed with the standard diet, the DRI of energy and zinc were 100% covered (2147 kcal, 10.4 mg, respectively), but not iron (2.9 mg). After 9 weeks of supplementation, body weight, and fat-free mass increased significantly by +11% (p = 0.033), and +11.8% (p = 0.033) in the RUTF group, but not in the Control group, while percentage body fat was comparable between groups (p = 0.888). In the RUTF group, fat free mass gain is higher in the patients on ART (+11.7%, n = 14; p = 0.0001) than in those without ART (+6.2%, n = 6; p = 0.032). Anemia decreased significantly with the supplementation, but zinc status, measured using plasma zinc concentration, remained unchanged. CONCLUSION: Improving PLWH' diet with 100 g RUTF for a long period has a positive impact on muscle mass and anemia but not on the zinc status of the patients. TRIAL NUMBER: NCT02433743, registered 29 April 2015.

RESUMEN

BACKGROUND: The first Ebola virus disease (EVD) epidemic in West Africa is unprecedented in its spread, complexity and severity. Comparing responses to spread of the virus in the three most affected countries - Guinea, Sierra Leone and Liberia- with that in Nigeria, Senegal and Mali where the epidemic was quickly brought under control may guide future mitigation efforts. METHODS: Literature from Pubmed. Google,Center for Disease Control and Prevention (CDC), Morbidity and Mortality Weekly Report (MMWR), World Health Organization's Updates and Ebola Response Reports: Results: The epidemic spread undiagnosed for three months from Meliandou in Guinea to its four rural prefectures and its. capital Conakry, two countires in Liberia and two districts in Sierra Leone. Control measures were hampered by traditional and faith healers offering -inappropriate treatments, as well as secret societies encouraging unsafe burial rituals. Whereas, in Nigeria, a case imported from Liberia on 20 July 2014 was diagnosed on the 3rd day; all primary, secondary and tertiary contacts were traced. Also, at a formal meeting, officials of Lagos state government discouraged treatment of EVD by faith healers. In Senegal, a single case imported from Guinea on 20 August 2014 was diagnosed on the 9th day, treated and further spread was prevented. In Mali, there were two waves of transmissions identified on 23 October and 12 November 2014 within 15 days of importation and the epidemic was controlled.There were no cases of EVD treated by any traditional healers or faith healers in Nigeria, Senegal and Mali. CONCLUSION: Education of traditional and faith healers on EVD will complement control measures for EVD epidemic.

RESUMEN

Use of medicinal plants is common and widespread throughout Africa, including in Senegal. Because efficacy has been demonstrated, public policies have been instituted that have allowed plant-based therapies to have an important role in general primary care. However, little is known about the cutaneous safety of many plant-based therapies. In this 6-month prospective study all cases of dermatitis induced or aggravated by exclusive use of medicinal plants were evaluated via skin allergy testing. The results were classified and compared with the available literature. Forty-three cases of plant-therapy-associated cutaneous reactions were identified, including worsening of existing conditions (56%), recurrence of a previously resolved condition (16%) and new dermatitis arising spontaneously (28%). In the cases where the condition was new, generalized exfoliative dermatitis occurred in 42% of cases with an average time of onset of 9 days. Specific plants were identified in 65% of cases and included 18 varieties. The frequency and severity of plant-induced cutaneous reactions should be the basis for the creation of a phytovigilance programme and re-evaluation of how traditional medicine is used in the general population. When irritation occurs, identification of the responsible plant and allergy testing should be the first steps towards relieving symptoms.

RESUMEN

A pilot study of market surveillance in Senegal has been performed analyzing best selling drugs from an official pharmacy and a street market in two principal cities of Senegal and some traditional preparations from herbal medicine from the same market. A simple and rapid gas chromatography method with mass spectrometry detection has been applied after a liquid-liquid extraction of pharmaceutical products and traditional preparations at acidic, neutral and basic pH with chloroform-isopropanol (9:1, v/v). The assay was validated in the range from 10mg to 250 mg/g powder preparations with good determination coefficients (r(2)≥ 0.99) for the calibration curves. At three concentrations spanning the linear dynamic ranges of the calibration curves, mean recoveries of substances under investigation were always higher than 90% and intra-assay and inter-assay precision and accuracy were always better than 15%. The four best selling drugs purchased from a Dakar local pharmacy exactly contained the amount of active principles reported in the respective labels while the best selling drugs freely purchased from Kaolack market contained an amount of active ingredients lower than that declared on the label. No pharmacological active compound, but salicylic acid was found in one of the traditional herbal preparations. This pilot study showed that whereas official drugs sold in pharmacies at prices accessible for a very few portion of the population contained the amount of active principles as reported in the labels, those from street market bought by the majority of population contained an amount of active ingredients lower than that declared on the label and finally traditional herbal preparations seldom contain pharmacological active principles.
