Internal Hernia through an Ovarian Cyst: Another Anatomical Particularity
Sawadogo Yamba Elie, Maïga Check Abdoul Fatao, Sam Aristide, Kambou Ollo, Ouédraogo Ida, Sanou Yves, Savadogo Julien, Kafando Roch, Ouangré EdgarThe authors describe a rare case of small-bowel obstruction caused by an internal hernia through a right ovarian cyst in a 52-year-old woman. Pre-operative CT suggested obstruction with a co-existing ovarian cyst, and laparotomy confirmed an incarcerated, perforated ileal loop that required wedge resection and cystectomy. The patient recovered uneventfully and was discharged on postoperative day 4. The report highlights an exceptional anatomical route for internal herniation and underscores the value of imaging for early suspicion.

Missed opportunities for hospital referral of young children with severe pneumonia identified at primary care using pulse oximetry: an analysis from the AIRE study in West Africa
Désiré Lucien Dahourou,1,2 Désiré Neboua,3 Kessièdé Gildas Boris Hedible ,2 Zineb Zair,2 Sarah Louart ,4 Jean-Paul Yassa Guilavogui,5 Abdoul Guaniyi Sawadogo,6 Bertrand Meda,7 Solange Ouédraogo Yugbaré,8 Ibrahima Sory Diallo,9 Abdoul Aziz Diakite,10 Hannatou Abarry Souleymane,11 Valéry Ridde ,12,13 Valériane Leroy ,2 for the AIRE Research Study GroupChildhood Illness (IMCI) guidelines, healthcare workers
(HCWs) should refer all severe pneumonia among children
under 5 seen in primary care in resource-limited
settings.
We investigated the frequency and correlates of missed
opportunities for hospital referral (MOHR) of clinical severe
pneumonia. Our study was embedded within the Améliorer
l'Identification des détresses Respiratoires chez l'Enfant
project, which involved the routine implementation of
pulse oximetry (PO) within IMCI consultations at primary
healthcare centres (PHCs) in West Africa: Burkina Faso,
Guinea, Mali and Niger.
Methods All children aged 2–59 months attending IMCI
consultations in 16 PHCs and classified as severe cases
using IMCI+PO were enrolled into a prospective cohort
for 14 days, with parental consent. We estimated the
rate of MOHR for IMCI-defined
severe pneumonia, which

Availability and quality of raw materials used in intensive poultry farming in Burkina Faso: The case of the city of Ouagadougou
Zampou Yasmine Jessica Irène*1,2, Gnanda Bila Isidore2, Sanou Sita2, Zare Yacouba2, Traore Boureima1, Ky Inoussa3, Zongo Moussa1Feed, especially quality feed, is one of the major challenges facing intensive peri-urban poultry farming in Burkina Faso. The aim of this study was to assess the availability and the quality of poultry feed in the city of Ouagadougou. Indeed, a survey was conducted at the main livestock markets in this city to inventory the raw materials (organic and mineral sources) that are marketed for poultry feeding. A total of 223 samples of organic raw materials and 22 mineral source samples were collected and analyzed by standard methods to determine their composition and qualities. The results generated indicate that, excluding rice bran, sesame seeds, and peanuts, most of feeds of organic basing inventoried and analyzed, contained acceptable crude cellulose (CC) levels, qualifying them as single concentrate feeds. Peanut, sesame and soybean seeds showed fairly good crude protein (CP) contents,...

Substitution of Fish Meal with Poultry Intestine Meal and Domestic Fly Larvae (Musca domestica) in the Diet of Juvenile Clarias gariepinus
Badioula Coulibaly1, Halidou Komi2, Armel Djerma3, Nessan Désiré Coulibaly4 & Moussa Zongo5The use of fishmeal and fish oil as ingredients in fish feed increases production costs and has long-term environmental impacts. This study aims to investigate alternative protein sources to fishmeal in fish feed to reduce production costs. To achieve this, maggot meal and poultry intestine meal were incorporated into feed and administered to African catfish juveniles to evaluate their growth, production costs, and assess their welfare. Nine iso-protein (42.5% protein) and iso-lipid (11.7% lipids) diets were formulated using these byproducts. The control diet (D1) contained fishmeal as the sole major protein source; in diets D2 to D5, fishmeal was replaced with maggot meal at rates of 25%, 50%, 75%, and 100%. From D6 to D9, the same substitution was made using poultry intestine meal. Fingerlings with an initial average weight of 13.73±0.23 g were placed in 27 hapas arranged in triplicate...

Analysis and optimal control of a fractional-order model of a vector-borne disease
Ali Traoré; Rosaire Ouedraogo; Hamadoum DickoIn this paper, a fractional-order model has been developed to study the transmission dynamics of a vector-borne disease. The use of fractional calculus, particularly through the Caputo derivative, provides a mathematical framework that accounts for memory effects and long-term dynamics often observed in vector-borne diseases. The difference between fractional-order and integer-order derivatives is reflected in the memory effect, which allows for greater accuracy in modeling real epidemiological dynamics. The basic reproduction number is calculated, and a qualitative stability analysis of the equilibria is provided. Two control strategies are applied, namely the rate of human protection and the rate of vector control interventions, with the aim of minimizing the number of infected individuals. Numerical simulations are carried out to illustrate the theoretical results obtained.

EFFET DE DEUX FORMULES ALIMENTAIRES DE PRE VULGARISATION SUR LES PERFORMANCES PONDERALES ET LES RENDEMENTS CARCASSES DES PORCS EN CROISSANCE : CAS DES ELEVAGES DES ZONES PERIURBAINES DE KOUDOUGOU ET DE REO, AU BURKINA FASO
GNANDA Isidore Bila, SAMA Pagnaguédé, ZARE Yacouba, OUOBA-IMA Sidonie Aristide, YODA Gildas Marie-Louis, ZONGO MoussaIl s’est agi d’évaluer l’impact nutritionnel de deux (2) aliments composés de prévulgarisation élaborés par la Recherche sur la performance de croissance des porcs. L’étude a été conduite en zone périurbaine de deux villes du Burkina Faso et a porté sur 86 porcelets locaux et métissés âgés de 3 à 6 mois. L’effet de ces deux aliments composés (AC1 et AC2) a été évalué sur le gain pondéral et les rendements carcasses des porcs de l’étude et ce, en comparaison avec celui des rations paysannes (témoin) durant 105 jours. Les poids finaux des porcs alimentés à l’AC1 (48,76±14,38 kg) et de ceux alimentés à l’AC2 (50,12±14,09 kg) ont été significativement (P≤0,05) plus élevés que ceux des porcs nourris aux rations paysannes (29,87±8,48 kg). Les marges bénéficiaires des porcs alimentés aux rations AC1 et AC2 ont été respectivement de 4718 F CFA et 4 791 F CFA/porc. Chez les porcs nourris aux rati...

Framework for assessing genetic variation in livestock using demographic, pedigree, and genomic measures
Gábor Mészáros, Ino Curik, Dominique Ouedraogo, Jack Windig, Gregoire Leroy, Yuri Tani Utsunomiya, Pamela Burger, Licia Colli, Chang Xu, Paul Boettcher, Christian Looft and Johann SoelknerGenetic variation within livestock populations underpins global food security, resilience, and the long-term sustainability of breeding programs. Despite its fundamental role, harmonized approaches for assessing and monitoring genetic variation across data sources remain limited. This review provides an integrated framework for assessing genetic variation in livestock using demographic, pedigree, and genomic data, developed by FAO experts and international collaborators. Demographic indicators offer essential insight into population size, sex ratio, and reproductive structure, while pedigree data allow detailed evaluation of genetic relatedness, inbreeding, and effective population size (Ne) over time. Genomic information now provides unprecedented accuracy in characterizing allelic variation, population structure with admixture, and the dynamics of inbreeding and drift. Each data source...

Potentials for Promoting Oil Products Identified from Traditional Knowledge of Native Trees in Burkina Faso.
Amadé Ouédraogo Department of Plant Biology and Physiology, University of Ouagadougou Anne Mette Lykke Department of Bioscience, Aarhus University Benjamin Lankoandé Department of Plant Biology and Physiology, University of Ouagadougou Gabin Korbéogo Department of Sociology, University of OuagadougouOil products from native trees are far from fully exploited in West Africa. Only well-known species like shea (Vitellaria paradoxa C.F. Gaertn.) and oil palm (Elaeis guineensis Jacq.) receive attention. We used quantitative questionnaires in 12 villages in Western Burkina Faso to assess the knowledge of four ethnic groups on 28 tree species and how their oil is used. Sixteen species were used the most. Among them, V. paradoxa, E. guineensis, Carapa procera DC., Pentadesma butyracea Sabine and Lophira lanceolata Tiegh. ex Keay received the most citations. Oils were used for soap (22%), food (21%), medicine (19%), body care (18%) and hair care (14%). Significant differences were found among ethnic groups concerning knowledge and preferences of oil products. Apart from the well-known species, C. procera, L. lanceolata and P. butyracea appear to be promising species for promotable oil produc...

Genre et éthique environnementale au Burkina Faso : Une approche empirique de l’éthique du care environnemental chez des Sanan
Gabin Korbéogo University Joseph Ki-ZerboLes effets induits par les variations et les inégalités environnementales ont mis sous les feux des projecteurs la nécessité de trouver des stratégies qui favorisent l’exploitation durable et équitable des ressources naturelles par les femmes et les hommes et qui assurent la reproduction des humains et des non-humains. Cette recherche empirique explore, sur la base d’une perspective de genre, les interrelations entre les rapports conceptuels et les rapports utilitaires que les Sanan entretiennent avec l’environnement. Les résultats d’analyse révèlent qu’il y existe une relation d’homologie structurale entre le système symbolique et la praxis sociale. Chez les Sanan, le pouvoir masculin dans le gouvernement de nature est rendu possible par le contrôle et l’appropriation de la fécondité des femmes, de leur savoir-faire comme du produit de leur force de travail par les hommes.

Le goût de la scène. Éléments d’une sociologie de la relation théâtrale à Ouagadougou (Burkina Faso)
Gabin Korbéogo University Joseph Ki-ZerboQue voit le sociologue lorsque la société se met en scène ? Cette question
qui fonde le projet heuristique de la sociologie de l‟art théâtral constitue le
fil conducteur de cet article. Le théâtre est un espace de jeu et de
compétition entre une pluralité d‟acteurs dont les compétences et les attentes
artistiques et culturelles sont différenciées. Cet article montre que la
préférence et la relation théâtrales des Ouagalais diffèrent selon leur origine
sociale et leur style de vie. Ainsi, plus les individus sont dotés en ressources
économiques et culturelles Ŕ notamment le titre scolaire qui contribue à la
formation du goût artistique et culturel au même titre que l‟origine sociale -
plus ils sont disposés à aimer l‟art théâtral et à comprendre les messages qui
y sont véhiculés. Par contre, lorsque le niveau socioéconomique et culturel
des indiv...
