Factor of Adoption of Organic Cotton in Southern Mali in the Villages of Kolodieba and Yanfolila

Organic cotton has started in 2004 in Mali in the context of a serious crisis in the conventional cotton   production system. It is all the more important for developing countries like Mali where agriculture, one of the pillars of the economy, remains heavily dependent on chemical pesticides. The aim of this study is to analyze the adoption of organic cotton production in the villages of Kolondieba and Yanfolila in southern Mali. Our survey involved 114 people including 48 organic cotton producers and 67 conventional cotton producers. Data were collected through individual interviews based on questionnaires. The analysis of the adoption of organic cotton carried out using a logistic regression model showed that the socio-economic characteristics of producers as well as the sex and education of producers are the main factors influencing their choice of production or not organic cotton. Women prefer organic production more than conventional production. This allows them not to depend on their husbands for inputs but also to have their own fields. Producers who have a very large number of people in the family, producers with schooling, as well as producers with a lot of beef are more apt to adopt organic cotton.

Epilepsie et permis de conduire au Mali : connaissances, attitudes et pratiques des moniteurs d’auto-école et des candidats au permis de conduire

Introduction: L’un des sujets les plus controversés dans le domaine de l’épilepsie est la problématique de la conduite chez l’épileptique.Objectif: Nous avons initié une étude, en collaboration avec l’Agence Nationale de la Sécurité Routière au Mali (ANASER), ayant pour but de faire l’état des lieux sur les connaissances, attitudes et pratiques des conducteurs, moniteurs et inspecteurs d’auto-écoles en matière d’épilepsie.Methode: Il s’agissait d’une étude longitudinale, prospective, descriptive et analytique qui s’est déroulée de juin 2009 à juin 2010. Elle a porté sur 31 auto-écoles du district de Bamako. 568 personnes ont été interrogées (488 candidats au permis de conduire, 70 moniteurs d’auto-école et 10 inspecteurs).Resultats: Près de 60 % des personnes interrogées accordaient une origine surnaturelle à l’épilepsie ; plus de 85 % indiquaient que l’épilepsie était incompatible avec la conduite automobile. Plus de la moitié ignorait l’existence d’une réglementation. Près de 70 % pensaient que l’épilepsie était pourvoyeuse d’accident de la voie publique.Conclusion: A l’instar de nos précédentes études communautaires au Mali, ce travail a permis de mettre l’accent, d’une part, sur l’importance des connaissances erronées sur l’épilepsie et, d’autre part, sur la nécessité d’actualiser la réglementation en matière de conduite de véhicules motorisés pour ces patients.Mots clés: Attitudes, Épilepsie, Mali, Permis de conduire, Conduite automobileEnglish Title: Epilepsy and driving licence in Mali : knowledge, attitudes and practices of driving schools monitors and the candidates for the licenceEnglish AbstractBackground: One of the most controversial topics in the field of epilepsy remains the issue of driving license for epileptic patients.Purpose: We initiated a study in collaboration with ANASER (National Agency for Road Safety in Mali) with the goal, on one hand, of assessing the knowledge, attitudes and practices of drivers and driving school authorities on epilepsy and, on the other hand, to analyze the current regulations on issuance of license to epileptic patients.Methods: Il s’agissait d’une étude longitudinale, prospective, descriptive et analytique qui s’est déroulée de juin 2009 à juin 2010. We interviewed 568 sujects, including 488 candidates for driver’s license, 70 driving school monitors and 10 inspectors.Results: About 60% gave a supernatural origin of the disease, and more than 85% believed that epilepsy was incompatible with driving. More than half were unaware of regulations. Approximately, 70% of respondents believed that epilepsy was a contributory factor to road accident.Conclusion: As in our previous community studies in Mali, this study emphasizes the importance of misconceptions about epilepsy, and has shown the need to update the regulations regarding the driving of motorized vehicles for these patients.Keywords: Epilepsy, Attitudes, Driving , Driving License, Mal

Surgical complications of Pica syndrome: About 3 cases

The Pica syndrome is an eating disorder characterized by an excessive or abnormal desire to consume a non-nourishing substance which can be relatively harmless, or potentially harmful for the health. It is a rare affection secondary to the accumulation of diverse natured foreign bodies inside the digestive tract and more especially at the stomach level. Gastro-intestinal localization is the most frequent, and can remain asymptomatic for a long time. Treatment is surgical. We report 3 cases of digestive complications of Pica syndrome

Study of the effectiveness of training Malian social and health agents in female genital cutting issues and in educating their clients

This report documents findings of a study to assess the education and training of social and healthcare workers in Mali regarding female genital cutting (FGC). After two decades of campaigning against FGC in Mali, the results are not satisfactory when compared to the levels of human and financial investment. The Mali Division of Family and Community Health, with technical support from the Population Council, conducted this research to highlight certain issues related to the practice of FGC in Mali, in particular health consequences and the role health personnel can play in eradicating the practice. The continued prevalence of FGC among dominant ethnic groups and the risk of its spreading to minority ethnic groups which do not traditionally circumcise females justify the continuation and extension of the campaign. Future research avenues, such as ways to improve IEC tools and training in health facilities, and improving outreach programs particularly among youths, should be explored

Pyronaridine-artesunate or dihydroartemisinin-piperaquine combined with single low-dose primaquine to prevent Plasmodium falciparum malaria transmission in Ouélessébougou, Mali: a four-arm, single-blind, phase 2/3, randomised trial.

BACKGROUND: Pyronaridine-artesunate is the most recently licensed artemisinin-based combination therapy. WHO has recommended that a single low dose of primaquine could be added to artemisinin-based combination therapies to reduce Plasmodium falciparum transmission in areas aiming for elimination of malaria or areas facing artemisinin resistance. We aimed to determine the efficacy of pyronaridine-artesunate and dihydroartemisinin-piperaquine with and without single low-dose primaquine for reducing gametocyte density and transmission to mosquitoes. METHODS: We conducted a four-arm, single-blind, phase 2/3, randomised trial at the Ouélessébougou Clinical Research Unit of the Malaria Research and Training Centre of the University of Bamako (Bamako, Mali). Participants were aged 5-50 years, with asymptomatic P falciparum malaria mono-infection and gametocyte carriage on microscopy, haemoglobin density of 9·5 g/dL or higher, bodyweight less than 80 kg, and no use of antimalarial drugs over the past week. Participants were randomly assigned (1:1:1:1) to one of four treatment groups: pyronaridine-artesunate, pyronaridine-artesunate plus primaquine, dihydroartemisinin-piperaquine, or dihydroartemisinin-piperaquine plus primaquine. Treatment allocation was concealed to all study staff other than the trial pharmacist and treating physician. Dihydroartemisinin-piperaquine and pyronaridine-artesunate were administered as per manufacturer guidelines over 3 days; primaquine was administered as a single dose in oral solution according to bodyweight (0·25 mg/kg; in 1 kg bands). The primary endpoint was percentage reduction in mosquito infection rate (percentage of mosquitoes surviving to dissection that were infected with P falciparum) at 48 h after treatment compared with baseline (before treatment) in all treatment groups. Data were analysed per protocol. This trial is now complete, and is registered with ClinicalTrials.gov, NCT04049916. FINDINGS: Between Sept 10 and Nov 19, 2019, 1044 patients were assessed for eligibility and 100 were enrolled and randomly assigned to one of the four treatment groups (n=25 per group). Before treatment, 66 (66%) of 100 participants were infectious to mosquitoes, with a median of 15·8% (IQR 5·4-31·9) of mosquitoes becoming infected. In individuals who were infectious before treatment, the median percentage reduction in mosquito infection rate 48 h after treatment was 100·0% (IQR 100·0 to 100·0) for individuals treated with pyronaridine-artesunate plus primaquine (n=18; p<0·0001) and dihydroartemisinin-piperaquine plus primaquine (n=15; p=0·0001), compared with -8·7% (-54·8 to 93·2) with pyronaridine-artesunate (n=17; p=0·88) and 50·4% (13·8 to 70·9) with dihydroartemisinin-piperaquine (n=16; p=0·13). There were no serious adverse events, and there were no significant differences between treatment groups at any point in the frequency of any adverse events (Fisher's exact test p=0·96) or adverse events related to study drugs (p=0·64). The most common adverse events were headaches (40 events in 32 [32%] of 100 participants), rhinitis (31 events in 30 [30%]), and respiratory infection (20 events in 20 [20%]). INTERPRETATION: These data support the use of single low-dose primaquine as an effective supplement to dihydroartemisinin-piperaquine and pyronaridine-artesunate for blocking P falciparum transmission. The new pyronaridine-artesunate plus single low-dose primaquine combination is of immediate relevance to regions in which the containment of partial artemisinin and partner-drug resistance is a growing concern and in regions aiming to eliminate malaria.

Peoples’ attitude toward COVID-19 vaccine, acceptance, and social trust among African and Middle East countries

Background: To end the COVID-19 pandemic, a large part of the world must be immune to the virus by vaccination. Therefore, this study aimed to gauge intent to be vaccinated against COVID-19 among ordinary people and to identify attitudes towards vaccines and barriers for vaccine acceptance. Methods: The study population comprises 1880 people residing in different countries that answer a prepared questionnaire. The questionnaire topics are demographics, historical issues, participants’ attitudes and beliefs regarding vaccines, concerns, and vaccine hesitancy. Results: Attitudes and beliefs relating to vaccines in general, and the COVID-19 vaccine, were ascertained. Overall, 66.81% of the contributors would like to be vaccinated against COVID-19, while %33.19 did not intend to be vaccinated. Reasons for COVID-19 vaccine hesitancy included concern regarding vaccine side effects, fear of getting sick from the uptake of the vaccine, and the absence of accurate vaccine promotion news. Individuals with higher education believe that India (68.6%) produces the best vaccine (P&lt;0.001), while healthcare workers think the Chinese vaccine (44.2%) is the best (P=0.020). Individuals with higher education have not been vaccinated, not be healthcare workers, and females were the most contributors to effective of the vaccine in reducing mortality from COVID-19 disease. Conclusion: Given the degree of hesitancy against COVID-19 vaccination, a multifaceted approach to facilitate vaccine uptake that includes vaccine education, behavioral change strategies, and health promotion, is paramount

Case Report: COVID-19 and Lassa Fever Coinfection in an Ebola Suspected Patient in Guinea

ABSTRACT. In this case report, we describe a clinical presentation and therapeutic history of a unique case diagnosed with Lassa fever and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in a 23-year-old man from Yomou prefecture in southeast Guinea identified with suspected Ebola Virus Disease (EVD) in the midst of an ongoing outbreak of that disease in the same region. On May 3, 2021, he was admitted to the Nzérékoré Epidemic disease treatment center where his clinical condition deteriorated significantly. Laboratory testing performed on the same day reveals a negative EVD polymerase chain reaction (PCR). Three days later, the patient was tested positive for SARS-CoV-2 and Lassa fever by reverse transcriptase PCR (RT-PCR) assays. Laboratory examination also indicated severe hematological and biochemical deteriorations in the patient. This case substantiates the need for systematic differential diagnosis during epidemic-prone disease outbreaks to better manage severely unwell patients.</jats:p

Countdown to 2030 : tracking progress towards universal coverage for reproductive, maternal, newborn, and child health

Building upon the successes of Countdown to 2015, Countdown to 2030 aims to support the monitoring and measurement of women's, children's, and adolescents' health in the 81 countries that account for 95% of maternal and 90% of all child deaths worldwide. To achieve the Sustainable Development Goals by 2030, the rate of decline in prevalence of maternal and child mortality, stillbirths, and stunting among children younger than 5 years of age needs to accelerate considerably compared with progress since 2000. Such accelerations are only possible with a rapid scale-up of effective interventions to all population groups within countries (particularly in countries with the highest mortality and in those affected by conflict), supported by improvements in underlying socioeconomic conditions, including women's empowerment. Three main conclusions emerge from our analysis of intervention coverage, equity, and drivers of reproductive, maternal, newborn, and child health (RMNCH) in the 81 Countdown countries. First, even though strong progress was made in the coverage of many essential RMNCH interventions during the past decade, many countries are still a long way from universal coverage for most essential interventions. Furthermore, a growing body of evidence suggests that available services in many countries are of poor quality, limiting the potential effect on RMNCH outcomes. Second, within-country inequalities in intervention coverage are reducing in most countries (and are now almost non-existent in a few countries), but the pace is too slow. Third, health-sector (eg, weak country health systems) and non-health-sector drivers (eg, conflict settings) are major impediments to delivering high-quality services to all populations. Although more data for RMNCH interventions are available now, major data gaps still preclude the use of evidence to drive decision making and accountability. Countdown to 2030 is investing in improvements in measurement in several areas, such as quality of care and effective coverage, nutrition programmes, adolescent health, early childhood development, and evidence for conflict settings, and is prioritising its regional networks to enhance local analytic capacity and evidence for RMNCH

Contribution of oenocytes and pheromones to courtship behaviour in Drosophila

<p>Abstract</p> <p>Background</p> <p>In Drosophila, cuticular sex pheromones are long-chain unsaturated hydrocarbons synthesized from fatty acid precursors in epidermal cells called oenocytes. The species <it>D. melanogaster </it>shows sex pheromone dimorphism, with high levels of monoenes in males, and of dienes in females. Some biosynthesis enzymes are expressed both in fat body and oenocytes, rendering it difficult to estimate the exact role of oenocytes and of the transport of fatty acids from fat body to oenocytes in pheromone elaboration. To address this question, we RNAi silenced two main genes of the biosynthesis pathway, <it>desat1 </it>and <it>desatF</it>, in the oenocytes of <it>D. melanogaster</it>, without modifying their fat body expression.</p> <p>Results</p> <p>Inactivation of <it>desat1 </it>in oenocytes resulted in a 96% and 78% decrease in unsaturated hydrocarbons in males and females, respectively. Female pheromones (dienes) showed a decrease of 90%. Inactivation of <it>desatF</it>, which is female-specific and responsible for diene formation, resulted in a dramatic loss of pheromones (-98%) paralleled with a two-fold increase in monoenes. Courtship parameters (especially courtship latency) from wild-type males were more affected by <it>desat1 </it>knocked-down females (courtship latency increased by four fold) than by <it>desatF </it>knocked-down ones (+65% of courtship latency).</p> <p>The number of transcripts in oenocytes was estimated at 0.32 and 0.49 attomole/μg for <it>desat1 </it>in males and females, respectively, about half of the total transcripts in a fly. There were only 0.06 attomole/μg <it>desatF </it>transcripts in females, all located in the oenocytes.</p> <p>Conclusion</p> <p>Knock-down results for <it>desat1 </it>suggest that there must be very little transport of unsaturated precursors from fat body to the oenocytes, so pheromone synthesis occurs almost entirely through the action of biosynthesis enzymes within the oenocytes. Courtship experiments allow us to discuss the behavioral role of diene pheromones, which, under special conditions, could be replaced by monoenes in <it>D. melanogaster</it>. A possible explanation is given of how pheromones could have evolved in species such as <it>D. simulans</it>, which only synthesize monoenes.</p
