Résumé :

SMMEs provide an indispensable framework for addressing unemployment, poverty and boosting the economy of a country. This report was impelled by the need to create and sustain enterprises within the hotels and restaurant sub-sector of the tourism industry in Libreville, Gabon. A quantitative methodology was embraced to disperse seventy self-administered questionnaires to owners and managers of hotels and restaurants. The results demonstrate that the key components which lead to the failure or non-sustainability of businesses include: limited access to start-up finance required to cover start-up and growth cost, the low return on investment, as well as the mismanagement of businesses. Given that job creation remains a dependable method for diminishing unemployment and poverty, establishing and sustaining businesses in Libreville would be a step in the right direction in Gabon. Keywords: venture creation, enterprise development, entrepreneurship challenges, Libreville. JEL Classification: M13, L26, L83

The number of existing cases hospitalized was significantly more than new cases. All levels of society were represented in our study: students (42); military (36); administratives (99); technicians (180); unemployed (295); and retired (146).

Résumé :

Description du sujet. La diminution drastique de terres arables à Libreville pousse de plus en plus les agriculteurs à s’installer dans les localités proches de la capitale gabonaise pour y pratiquer l’agriculture et ravitailler Libreville en produits agricoles.Objectif. La présente étude qui se déroule à quatre-vingt kilomètres de Libreville, a pour objectifs de : (1) déterminer certaines propriétés physico-chimiques et biologiques des sols de Kango, et de comparer les valeurs trouvées avec les valeurs seuil agronomiques, (2) relever les contraintes liées à la production agricole sur ces sols, et (3) proposer des solutions adéquates pour une exploitation agricole respectueuse de l’environnement.Méthodes. Des échantillons de sols ont été prélevés, et les analyses physico-chimiques et biologiques y ont été réalisées : le pH eau, le pH KCl, le carbone organique total, l’azote total, l’azote assimilable, le phosphore total, le phosphore assimilable, l’aluminium, les cations basiques, la capacité d’échange cationique, le taux de saturation en bases échangeables, la biomasse microbienne, le quotient microbien, les rapports azote microbien/azote total et carbone microbien/azote microbien.Résultats. Les sols prélevés sont argileux, ils ont des teneurs en carbone organique total, en azote total et en phosphore total agronomiquement convenables. Mais la très forte acidité, les teneurs en phosphore et azote assimilables, en cations basiques, le taux de saturation très bas et l’activité biologique constituent les principales contraintes à la production agricole.Conclusion. Le chaulage, l’apport de biochar et des amendements organiques sont des solutions à appliquer pour obtenir de bons rendements dans ces rendements dans ces sols dans le respect de l’environnement. Description of the subject. Faced with the drastic reduction of arable land in Libreville following the development of the city, more and more farmers and agro-industries are settling in localities close to the Gabonese capital where they can find land to exploit in to supply Libreville with agricultural products, such as the locality of Kango, located 82 kilometers from Libreville.Goals. The objectives of this study are (1) to determine certain physico-chemical and biological properties of the soils of Kango and to compare the values found with the agronomic threshold values, (2) to identify the constraints likely to limit agricultural production on these soils, and (3) to propose adequate solutions for an efficient and environmentally friendly agricultural exploitation.Methods. Soil samples were taken, and physico-chemical and biological analyzes were carried out: water pH, KCl pH, total organic carbon, total nitrogen, assimilable nitrogen, total phosphorus, phosphorus assimilable, aluminum, basic cations, cation exchange capacity, exchangeable base saturation rate, microbial biomass, microbial quotient, microbial nitrogen/total nitrogen and microbial carbon/microbial nitrogen ratios.Results. The soils sampled are clayey, they have agronomically suitable total organic carbon, total nitrogen and total phosphorus contents. But the very high acidity, the assimilable phosphorus and nitrogen, basic cations, the very low saturation rate and the biological activity constitute the main constraints to agricultural production.Conclusion. Liming, the addition of biochar and organic amendments are solutions to be applied to obtain good yields in these soils while respecting the environment.ls dans le respect de l’environnement.

Résumé :

À partir d’enquêtes de terrain réalisées auprès du mouvement rap à Libreville, Alice Aterianus apporte une analyse anthropologique des langages du politique développés autour de la pratique musicale au Gabon depuis le début des années 1990. En décrivant une campagne électorale tenue à l’occasion des élections présidentielles d’aout 2009, cet article présente les logiques d’interpénétration du réseau du rap et de l’environnement politique, et les enjeux contenus autour de différents modes de participation des rappeurs à la campagne, en les pensant comme autant de stratégies d’invention du politique et d’infléchissement du pouvoir mettant en débat la notion de démocratie au Gabon.

Résumé :

In this contribution, we examine the question of the transmission of Bantu languages from the generation of the parents to the generation of children, into the specific context of Gabon. Our results are based upon a sociolinguistic survey (Zuè Elibiyo, 2008) made in two different cities of Gabon. One of these cities is located in the north-west (Libreville), and the other one in the center (Lambaréné). The data analysis shows that French language is clearly the language which the great majority of the parents transmit to their children. Nevertheless, at least two Bantu local languages, Fang (A75) and Gisir (B41) are, to a certain extent, also spoken by adults to the children within the family context. Finally, we show that not all local languages of Gabon are really endangered, even though their transmission is globally in decline.

Résumé :

Following the observed increase of malaria prevalence among older children in Gabon, a descriptive observational study was carried out in 2012 to determine the prevalence of malaria in adults presenting with fever in two health centres of Libreville, the capital city of Gabon. Thick- and thin-blood smears for malaria diagnosis were performed in febrile individuals aged more than 15 years old. Age, use of bed nets, previous antimalarial drug treatment, clinical symptoms, chest radiography results, and available haemoglobin data were also recorded. Among the 304 patients screened, the global malaria frequency was of 42.1%(n=128/34).Plasmodium (P). falciparumwas the only species identified. The proportion of patients with a clinical malaria requiring parenteral treatment was 38.5%, whereas 47.5% of outpatients had uncomplicated malaria. According to WHO classification, 14 (19.7%) infected patients had severe malaria; neurological and respiratory symptoms tended to be more frequent in case ofP. falciparuminfection. Anaemia was found in 51.5% adults and none had severe anaemia. Almost half of adults consulting for fever in two health centres of the urban city of Libreville have malaria. The use of insecticide-treated bed nets, the screening, and the treatment of individuals withP. falciparummicroscopic and submicroscopic asymptomatic infection or clinical malaria should be emphasized to reduce the transmission.

Résumé :

Cet article examine l’impact de la transition numérique sur l’entrepreneuriat informel des femmes commerçantes à Libreville, au Gabon, et sur leur autonomisation économique. Utilisant une approche qualitative exploratoire et s’appuyant sur des entretiens semi-directifs avec des commerçantes de Libreville ainsi que divers acteurs (ONG, etc.), l’étude révèle que la transition numérique présente des opportunités, notamment en matière d’accès à l’information et aux services financiers ainsi que de renforcement des réseaux sociaux et du capital humain. Néanmoins, elle met également en évidence des défis significatifs, tels que l’accès limité aux technologies, des compétences numériques insuffisantes ainsi que l’existence de normes sociales et culturelles contraignantes. Des stratégies d’adaptation et de résilience élaborées par les femmes commerçantes pour faire face à ces obstacles sont identifiées. Ces constatations suggèrent des directions pour les décideurs politiques, les gestionnaires et les organisations désireux de soutenir l’entrepreneuriat féminin dans le cadre d’une numérisation en expansion.

Résumé :

In Africa and Gabon particularly, rampant urbanization, the increase in female professional activity, the break-up of the classic family model have induced new eating behaviors and consumption patterns. The development of the cold chain promotes the reduction of food losses, the conformity of products to quality requirements, market safety and the improvement of production. The cold chain is therefore an essential factor in food safety. In Gabon, national consumption needs are more or less covered by local production with regard to plantain, cassava, taro, yam and fish products. The coverage rate is zero for rice, wheat, fruit ballast, quite low for vegetables, meat and poultry. So much so that it is common to hear people say in Libreville: “I am going to buy the embalmed, how are we going to do it again?”. FAO 2008 defines food security as a state where "all human beings have, at all times, physical and economic access to sufficient, safe and nutritious food, enabling them to satisfy their energy needs and food preferences to carry out a healthy and active life » Our non-stratified sample includes teachers and ATOS staff from the ENS Libreville campus. A total of 100 questionnaires are distributed, only 88 are collected for the study. The survey conducted within the premises of the Superior Normal School of Libreville is not statistically representative of the whole country. The limitations of the study are related to its geographical coverage. The approach is based on the place of purchase and the type of purchase. This study shows that respondents determine the quality of what they buy by the eyes, the color, the smell and the place of purchase. As places of purchase they prefer supermarkets (Mbolo, CKDO). Many of them believe that the authorities do not pay enough attention to the quality of food. The objective of this work is to understand the processes that populations bring into play in the development of food quality.

Résumé :

To establish the immunohistochemical profile of the molecular markers of free-ranging breast carcinomas. Descriptive retrospective study over 3 years from July 2014 to September 2017. The tumour samples came from the Anatomical Pathology Laboratories of the Omar Bongo Ondimba Army Instruction Hospital and the University of Health Sciences. In total, the records of 60 patients with histologically proven breast carcinoma with the immunohistochemical study were included in the study. The following molecular markers, hormone receptors (estrogen receptors, progesterone receptors), the HER2/Neu oncogene, and the Ki67 cell proliferation marker, was identified using the Immunohistochemistry technique.The average age was 47.6 years, with extremes of 15 and 69 years. Depending on the location, the right breast was most commonly affected (50%). Histologically, there was a predominance of infiltrating ductal carcinomas (66.6%) and a majority SBR III grade (50%). This study revealed an immunohistochemical profile of positive hormone receptors: ERs + (13.3%); PRs + (8.3%) and a Ki67 profile positive in 10% of tumors. The molecular classification into 4 subtypes (Luminal A, Luminal B, HER2 and Triple Negative) places the Luminal A group in the first rank (33.3%) followed by the Luminal B (15%), Triple Negative (11.6%) and HER2 (8.3%). The present work is the first study reporting the immunohistochemical profile of molecular markers of mammary carcinomas in Gabon. It would be necessary to continue this study on a larger and wider cohort throughout Gabon because the knowledge of the immunohistochemical profile gives an indication of the origin of breast cancers and allows to consider better management of patients by a targeted therapy to avoid unnecessary toxic effects resulting from ineffective treatment.

Résumé :

Background: Exclusive breastfeeding from birth to six months of age has an unparalleled benefit on a child's growth and development. This survey aimed to assess the practice of exclusive breastfeeding (EBF) in Libreville and Lambaréné. Method: This is a prospective study, including mother-child pairs of infants taken to vaccination centers in Libreville (urban area) and Lambaréné (semi-rural area). The data collected included sociodemographic aspects of families, the children's characteristics, and the duration of EBF in months. Result: We included 552 mother-child pairs, 58% of whom were recruited (n = 320) in Libreville. The average age of mothers was 26.5 ± 6.4 years, while fathers were 33.3 ± 7.8 years. The mean age of children was 4.2 ± 3.1 months. Male participants were accounted for 52.2% (n = 288), while females 47.8% (n = 264). The mean duration of exclusive breastfeeding in the whole was 0.9 months. Six-month EBF was generally performed at 9.2% (n = 51, 95% CI = 7.1%-11.9%). The factors influencing the EBF were father’s level of education (all classes combined) (p = 0.025), marital status (p = 0.011), and residential area (OR = 3.40, p <0.001) Conclusion: The duration of exclusive breastfeeding in the two studied is lower than the WHO recommendations. The associated factors found are areas of work to be explored to encourage this important practice for our infants.

Résumé :

This report offers an account of an international workshop held at the Omar Bongo University in Libreville, Gabon, from 23 November to 27 November 2018. Bringing together specialists on and from Cameroon, Central African Republic, Chad, Congo, Equatorial Guinea, and Gabon, participants reflected on the ways in which different forms of violence have historically had – and continue to have – an impact on social fabrics and several dimensions of politics. The workshop also sought to relate these legacies of violence to the region’s economies of extraction. The region is confronted with social and political turmoil that receives little international attention. The combination of simmering and open instability and the relatively marginal position of the region vis-à-vis the wider continent risks propelling several countries into outright political strife with regional repercussions. The debates concluded that further thinking on how violence permeates every aspect of social and political life is much needed.

Résumé :

Aims: This study determined the prevalence and evolution of long COVID symptoms in patients hospitalized for severe COVID-19 at the CHUL intensive care unit in Libreville, Gabon. Study Design: Prospective, longitudinal, study. Place and Duration of Study: Infectiology Unit, Centre Hospitalier Universitaire de Libreville Hospitalier Universitaire de LibrevH (CHUL), between January 2021 and January 2022. Methodology: We included 144 patients (84 men, 60 women; median age 46.4 [16-88] years) hospitalized in the intense care unit for a RT-PCR- confirmed COVID-19 and who have accepted a one-year follow-up. All patients were consulted quarterly for 12 months. During the follow-up, existence, appearance and types of symptoms were sought at 3, 6 and 12-months post-hospitalization. Results: The prevalence of long COVID-19 was 52.1% (n=75/144). Fatigue (21.3%), cough (20.8%), sleep disorders (16.0%) and anxiety (11.1%) predominated at month-3. The main symptoms reported 6-months after the onset of infection were dyspnea (9.7%; n=14), anxiety (7.6%; n=11), fatigue (6.2%; n=9) and cough (3.5%; n=5). One year after, the persistent symptoms were anxiety (6.5%; n=9), dyspnea (1.4%; n=2). Most participants had only one symptom: 60% at month-3, 79.5% at month-6 and 77.8% at 12-months (p=0.04). Conclusion: The long COVID is frequent among patients hospitalized for severe form of SARS-COV-2 infection. It is imperative to continue generating information for appropriate prevention and monitoring measures to be adopted in Gabon.

Pour y parvenir, nous avons réalisé une enquête auprès de 287 clients du « Groupe CECA-GADIS » à Libreville au Gabon pour vérifier le modèle conçu à cet effet. Contrairement aux études antérieures, les résultats de cette étude montrent globalement que la performance logistique n’a pas d’impact sur la satisfaction des consommateurs et l’image du magasin. Par contre, c’est l’image du magasin et la satisfaction des consommateurs qui ont une influence significative sur leur fidélité selon cette recherche.

Résumé :

The first detection of canine parvovirus type-2 (CPV-2) was in the early 1970s, when it was known to cause severe gastroenteritis in dogs. However, it has evolved over the years into CPV-2a within 2 years, into CPV-2b after 14 years, into CPV-2c after 16 years and more recently CPV-2a-, 2b- and 2c-like variants reported in 2019, with a global distribution. Reports on the molecular epidemiology of this virus are missing in most African countries. The report of clinical cases among vaccinated dogs in Libreville in Gabon triggered the execution of this study. The objective of this study was to characterize circulating variants from dogs showing clinical signs suggestive of CPV that were examined by a veterinarian. A total of eight (8) fecal swab samples were collected, and all had positive PCR results. Sequencing, Blast analysis and assembly of two whole genomes and eight partial VP2 sequences were performed, and the sequences submitted to GenBank. Genetic characterization revealed the presence of CPV-2a and CPV-2c variants with predominance of the former. Phylogenetically, the Gabonese CPVs formed distinct groups similar to Zambian CPV-2c and Australian CPV-2a sequences. The antigenic variants CPV-2a and CPV-2c have not yet been reported in Central Africa. However, these CPV-2 variants circulate in young, vaccinated dogs in Gabon. These results suggest additional epidemiological and genomic studies are required in order to evaluate the occurrence of different CPV variants in Gabon and effectiveness of the commercial vaccines used against protoparvovirus in the country.

Résumé :

Background: Iron is essential for a child's growth. In the Gabonese general pediatric population, iron deficiency is the most widespread nutrient deficiency. Quid of the sickle cell children in Libreville, Gabon? Methods: We conducted a cross-sectional study including sickle cell children aged from 6 months to 15 years, with haemoglobin SS confirmed. Subjects included were examined in steady-state. Data collected were about the socioeconomic background of the families, medical history of the children. To determine iron status, we used: CRP, Ferritin, serum iron, Transferrin, total blood count cell and erythrocytic parameters. Results: We included 247 children; 128 boys (51.8%) and 119 girls (48.2%). The median age of the children was 8 years [1 year - 15 years]. Following definition criteria we found: 9% (95% CI [18.6% - 29.2%]) of iron deficiency, 67.6% (95% CI [62.2% - 73.8%]) of normal iron status, and 8.1% (95% CI [4.7% - 11.5%]) of iron overload. Iron deficiency was associated with a child’s rank >2, OR=2.1 (95%IC [1.2-6], p<0.001). Iron overload was associated with age >11 years OR=2.5 (95%IC [1.7-9], p<0.001); mothers’ low educational level OR=3.6 (945% IC [1.4-9], p=0.03); transfusion OR=10,5 (95%IC [1,9 – 53], p =.0.025); a last transfusion between 4 and 6 months OR=9.1 (95%IC [3.1-21], p<0.001). Conclusion: The majority of sickle cell children in our context has a normal iron status. Iron deficiency and iron overload should be monitor and treated according to associated factors, and greater studies are required to determine algorithms to assess and treat and iron imbalance.

Résumé :

Background: High-risk oncogenic human papillomaviruses (HPV) are the cause of sexually transmitted viral infection. Its persistence is a risk factor for precancerous lesions of the cervix, which will constitute the base of cervical cancer. In the world, the prevalence of high-risk oncogenic HPV is 66.7%, which is higher among women starting their sexual activity.Methods: An analytical cross-sectional study was conducted in high schools in Gabon regarding parents. The variables selected were the socio-cultural and demographic characteristics of the parents, their knowledge of human papillomavirus vaccination and their acceptability of HPV vaccination and finally the feasibility of HPV vaccination. The statistical test used was Pearson's Chi-square, and a difference was considered significant for p<0.05.Results: The majority of parents, 89%, were informed of the existence of cervical cancer. However, 73.4% of them were unaware of the existence of vaccination against cervical cancer. Only 2.4% of parents had vaccinated their daughters against cervical cancer at the time of the study. These parents only 53.4% expressed an interest in vaccinating their daughters in 53.4% of cases. The ability to vaccinate children is associated with the socio-professional status of parents (p˂0.000).Conclusions: The majority of parents approved school-based vaccination against human papillomavirus infections despite its reported cost and lack of information. The integration of anti-HPV vaccination into the expanded programme on immunization in Gabon will improve immunization coverage.

Résumé :

Aim: The aim of this study was to assess the trends of ITN use and age disparities among children attending for malaria diagnosis in the main sentinel site for malaria surveillance of Gabon. Methodology: Data were collected from September 2023 to October 2023 at the malaria sentinel site for malaria survey of the Regional Hospital of Melen in Gabon. Data from 2010 to 2020, including age, gender, years of screening and ITN use the night before the consultation were reported on a case report form. Results: Data from 13687 children were analyzed, the rate of ITN use was 57.7% (n=7902). The trend of ITN use decreased significantly from 76.2% in 2011 to 41.9% in 2017, with a slight increase until 2019 (54.9%). According to age, use of ITN was more frequently reported in infants (64.1%) and children aged between 2 to less than 5 years (57.1%) compared to older children (53.1%) and adolescents (51.2%) (P<0.01). Although the rate of mosquito net use significantly decreased in all the age groups, the odds of net use remained the highest in children under 5 years and lowest among the adolescents (P<0.01). Conclusion: The ITN use coverage is still insufficient in Libreville. Efforts should be done to achieve the universal coverage of ITN ownership and use toreduce malaria transmission in Gabon.

Résumé :

La présente étude se propose de comprendre et d’illustrer le processus d’intégration du XO dans une école primaire à Libreville au Gabon. Menée sous l’angle de la théorie de l’activité, elle aboutit à des tensions intrasystémiques induites par le peu d’ouverture du système d’activité des enseignants aux outils non recommandés par les programmes officiels, et à des tensions intersystémiques suscitées par la fragilisation des frontières aux frontières des systèmes d’activité impliqués dans le développement de l’élève en contexte. Alors que les tensions intrasystémiques tendent d’amorcer l’expansion de l’activité d’intégration du XO, les tensions intersystémiques tendent au contraire à la « paralysie » au point où il devenait difficile aux enseignants de donner un sens à l’utilisation du XO animée par une motivation à changer leur pratique de classe.

Résumé :

This study aimed at assessing the impact of urban agriculture on physicochemical soil properties and the metal uptake by some leafy vegetables cultivated in urban soils of Libreville, Gabon. Cultivated and uncultivated top-soil and vegetable samples were collected on two urban garden sites, and analyzed. The results showed that there was strong acidification and a decrease of nutrient and metal concentrations in soils due of agricultural practices. The metal transfer to plants was important, with the exception of iron. The non-essential metal cadmium and lead were not detectable in plant tissues. Amaranth accumulated more metals than other vegetables. Amaranth and Roselle were vegetables that preferentially concentrated metals in their leaves and can therefore be used for metal supplementation in food chain.
