FR2.2: Gender-based assessment of rice and rice seed production in Nioro hub, Senegal

In the central part of Senegal, farmers are threatened by some abiotic stress including salinity and toxicity such that farmers abandoned rice farming in some areas. The pressures to sustain the farmers' livelihood sources are intense, involving land hire in the less-affected areas. From a gender perspective, these conditions are particulary worrying because they are compromising the essence of the role of the woman in the household: rice growing for food in the lowland fields is a traditional activity of the woman, the man is involved in cash crop production in upland ecology (groundnut and millet). Hence producing rice is essentially the woman's contribution to the household's food consumption, noting that men are becoming involved in growing upland rice, with the introduction of suitable varieties. This study targeted to investigate the women and men specific seed needs, challenges, and opportunities to make rice and rice seed production more beneficial to women, by providing them stress tolerant verities for lowlands and identifying sustainable business models adoption and dissemination. We conducted focus group in three villages with separate groups of men; women and young people and quantitative data collection with a sample of 60 farmers in each village, to identify the constraints to rice farming and to assess the producer's awareness of this improved varieties. The abiotic stressors decimate the crops and then the stress tolerant varieties and production of seeds sparked a new interest in rice cultivation in this region. Additional efforts are required to implement sustainable business models for seed production

Profil clinique et évolutif des lésions de la peau et des parties molles chez les diabétiques en 2017 à la salle de pansement du Centre Marc Sankale de Dakar

Introduction: le but de notre étude était de déterminer le profil clinique et évolutif des lésions de la peau et des parties molles des sujets diabétiques suivis à la salle de pansement. Méthodes: il s'agissait d'une étude observationnelle descriptive et analytique menée du 1er janvier au 31 décembre 2017 à la salle de pansement du centre Marc Sankale de Dakar. Notre étude a porté sur les sujets diabétiques ayant consultés à la salle de pansement. Résultats: au total, 37173 actes de soins ont été enregistrés au centre Marc Sankale. Les activés de soins à la salle de pansement représentaient 16418 cas soit une prévalence de 14,16%. L'âge moyen était de 56,6 ± 12 ans et le sex ratio (H/F) de 0,88. Le diabète de type 2 prédominait (78,97%) et la durée moyenne du diabète était de 8,06 ± 7,9 ans. La glycémie capillaire moyenne était de 2,4 ± 1 g/l. La neuropathie diabétique était présente chez 72,33% des cas. Les lésions se situait aux membres dans 93,98% (1185 cas). Les lésions les plus représentatives étaient l'ulcère (46,76%), l'abcès (13,46%), le phlegmon (13,20%), la gangrène (8,41%), l'érysipèle (3,78%), le mal perforant (3,53%), l'intertrigo (3,95%). Les lésions étaient infectieuses (61,41), non infectieuses (33,50%), vasculaires pures (1,57%) et Mixtes (3,70%). Sur les 1189 patients 7,57% avaient présentés une ostéite. Les germes retrouvés étaient des bactéries grams positifs (12,70%), grams négatifs (23,80%). L'amputation était corrélée à la topographie de la lésion (p=0.00), au type de lésion (p=0.000), à l'ancienneté du diabète (p=0,02), au type de diabète (p=0,008), à la présence d'ostéite (p=0,006). L'amputation etait mineur (43,33%), et majeur (37,43%). Nous avons enregistré 70 décès (5,89%). Conclusion: les lésions de la peau et des tissus mous restent dominées par le pied diabétique. La mortalité est non négligeable et le risque d'amputation était statistiquement corrélé à la topographie, au type de lésion, à l'ancienneté et le type de diabète et à l'existence d'ostéite

Une lesion cutanée persistante non cicatricielle depuis 3 ans: le pyoderma gangrenosum

Le pyoderma gangrenosum (PG) est une dermatose neutrophilique non infectieuse rare souvent méconnue. Il se présente généralement par des ulcérations cutanées inflammatoires, très douloureuses et d'évolution rapide. Il est fréquemment retrouvé dans un contexte de néoplasie, de pathologies inflammatoires digestives, rhumatologiques et/ou hématologiques. Son diagnostic est très souvent tardif après de multiples échecs thérapeutiques. Nous rapportons un cas de pyoderma gangrenosum dont le diagnostic n'a pas été criant. Un patient a été admis dans notre service pour une lésion dermatologique persistante et d'évolution défavorable malgré les débridements et l'administration d'antibiotiques. Il était suivi pour un cancer de la prostate, une hypertension artérielle et un asthme. Du fait des anomalies biologiques observées telles qu'une hyperleucocytose à polynucléaires neutrophiles avec myélémie à myélocytes et métamyélocytes, sans blastose sanguine et une anémie normochrome normocytaire, une leucémie myéloïde chronique a été évoquée chez ce patient. Elle a par la suite été infirmée devant les différents examens complémentaires non concluants. C'est ainsi que le diagnostic de PG a été évoqué et confirmé à l'examen anatomopathologique montrant un aspect histopathologique d'un tissu de granulation concordant avec un pyoderma gangrenosum et une absence de signe histologique de malignité. L'institution d'un traitement à base de corticothérapie a abouti à la guérison

Dyslipidemia, obesity and other cardiovascular risk factors in the adult population in Senegal

Introduction: According to the WHO, 50% of deaths worldwide (40.1% in developing countries) are due to chronic non-communicable diseases (NCDs). Of these chronic NCDs, cardiovascular diseases remain the leading cause of death and disability in developed countries. The Framingham study has shown the importance of hypercholesterolemia as a primary risk factor. In Senegal, the epidemiology of  dyslipidemia and obesity are still poorly understood due to the lack of comprehensive studies on their  impact on the general population. This motivated this study to look into the key epidemiologic and socio-demographic determinants of these risk factors. Methods: It was a cross-sectional descriptive epidemiological survey which included 1037 individuals selected by cluster sampling. Data were collected using a questionnaire following the WHO STEPwise approach. Socio-demographic, health and biomedical variables were collected. P value Results: The average age was 48 years with a female predominance (M: F of 0.6). The literacy rate was 65.2% and 44.7% of participants were from rural areas. The prevalence of hypercholesterolemia, hyperLDLemia, hypoHDLemia, hypertriglyceridemia and mixed hyperlipidemia were 56%, 22.5%, 12.4%, 7.11% and 1.9% respectively. One in four was obese (BMI> 30kg/m2) and 34.8% had abdominal obesity. The main factors significantly associated with dyslipidemia were obesity, urban dwelling, physical inactivity and a family history of dyslipidemia. Conclusion: The prevalence of dyslipidemia, obesity and other risk factors in the population was high needing immediate care for those affected and implementation of prevention strategies.Key words: Dyslipidemia, obesity, cardiovascular, risk factors, Saint Loui

Consumer willingness to pay for rice fragrance: Evidence from Senegal

In response to increasing urban consumer demand for fragrant rice, rice breeders have developed local, fragrant rice varieties in Senegal. We assess the drivers of demand for rice fragrance by eliciting urban consumers’ willingness to upgrade non-fragrant to fragrant rice and willingness to pay (WTP) for domestic versus imported fragrant rice. We conducted experimental auctions with 120 urban consumers in Dakar and analyzed WTP for rice fragrance through a double hurdle model. The results indicate that variables such as ethnicity, household size, and awareness of fragrance and local fragrant rice significantly affect consumers’ willingness to upgrade non-fragrant to fragrant rice. Urban consumers with positive buying intentions towards domestic fragrant rice are very likely to buy it and pay price premiums of 64 FCFA/kg. However local fragrant rice is slightly discounted compared to imported fragrant Thai Hom Mali rice. Our findings suggest that there is an important market for domestic fragrant rice in Dakar and that local rice is competitive with imported rice on that urban market

Willingness to Pay for Enhanced Food Quality: Rice Parboiling in Benin

In Benin, traditional parboiling is still widely practiced among rice processors, resulting in inferior grain quality. A new parboiler was introduced to improve the milling yield and quality of local rice. We conducted Vickrey second price auctions followed by a consensus session to elicit rural Beninese consumers’ willingness to pay for rice obtained through the new parboiler and two locally innovated parboilers. Relative to traditionally parboiled rice, consumers were willing to pay price premiums of 9–13% for rice obtained through a local parboiler using a container of which the bottom is a perforated metal, 27% for rice obtained through a local parboiler using wooden sticks at the bottom of the pot, and 25–34% for rice parboiled through the improved parboiler. Bids were influenced by the presentation order of the products according to perceived quality. Bids were also higher when participants had been informed on the benefits of improved parboiling techniques, a crucial insight for developing marketing and communication strategies for this improved quality product

Experimental auctions, collective induction and choice shift: Willingness-to-pay for rice quality in Senegal

We propose a collective induction treatment as an aggregator of information and preferences, which enables testing whether consumer preferences for food quality elicited through experimental auctions are robust to aggregation. We develop a two-stage estimation method based on social judgment scheme theory to identify the determinants of social influence in collective induction. Our method is tested in a market experiment aiming to assess consumers’ willingness-to-pay for rice quality in Senegal. No significant choice shift was observed after collective induction which suggests that consumer preferences for rice quality are robust to aggregation. Almost three quarters of social influence captured by the model and the variables was explained by social status, market expertise and information
