Background: Breast cancer is the dominant cancer in women in both developed and developing countries. The objective of this study was to assess the knowledge, attitudes, practices and factors associated with early breast cancer screening among women in the Municipality of Abomey-Calavi in Benin. Methods: This was a cross-sectional, descriptive, analytical study with prospective data collection from October 1 to 8, 2018, involving 1740 women in the Municipality of Abomey-Calavi, aged 18 years or older and selected by WHO four-stage random cluster sampling. Consenting women who were mentally competent, 18 years of age or older at the time of the survey, and residing continuously in the Municipality of Abomey-Calavi for the last six months prior to the survey were included. On the other hand, women who belonged to a breast cancer prevention service, women in whom secondary screening was noted, or non-consenting women were not included. The initial minimum size was estimated by the Schwartz formula with a cluster effect of k = 2. Information was collected by questionnaire survey, entered with Epidata 3.1. Fr and analyzed with R Studio 3.5.1. software. Results: The mean age of the women surveyed was 32.0 ± 11.5 years with a range of 18 and 71 years. Regarding knowledge, the clinical manifestation known by the majority of women was the presence of a nodule (68.50%). In the series, 1308 (75.17%) declared having heard about breast cancer once before, either on the radio, television or from friends and 726 (55.50%) had heard about breast cancer screening. Five hundred and twelve (70.52%) of the 726 who had heard of breast cancer said they knew that breast cancer could be screened earlier. Breast self-examination was the most cited screening method (67.58%). The disease is of natural origin according to 37.84% of them. Regarding attitudes and practices, the prevalence of early breast cancer screening was 12.93%, of which 11.67% declared that they had checked themselves to kno

Coula edulis is non-timber forest product (NTFP) used in Africa for its hazelnuts, which contain edible seeds with a demonstrated nutritional potential. However, there have been very few scientific studies of this species in the Republic of Congo. Thus, the aim of the current study was therefore to determine the fatty acid composition of the oil extracted from Coula edulis hazelnut seeds collected at random in the Republic of Congo. The oil was extracted using the Soxhlet method and its fatty acid composition was determined by gas chromatography. The extracted oil from Coula edulis hazelnut kernels is rich in monounsaturated fatty acids (95.28%), particularly oleic acid (94.5%), which classifies it as an oleic oil and gives it interesting nutritional and therapeutic properties. On the other hand, saturated fatty acids (4.15%) and polyunsaturated fatty acids (0.35%) are not well represented. Its low poly-unsaturated fatty acid content makes it more stable when stored at room temperature.

Introduction: Antenatal care (ANC) contributes to the reduction of maternal and neonatal morbidity and mortality. The study aimed to investigate the determinants of the low proportion of pregnant women seen for first antenatal care in the first trimester of pregnancy at the urban medical center of Koudougou, Burkina Faso. Materials and Methods: This was a cross-sectional study with data collection from June 08 to August 18, 2021. It involved a sample of 302 participants including 280 pregnant women and 22 maternity providers. Semi-structured individual interviews, non-participant observation, and a literature review were used. Results: Pregnant women age 20 and over, knowledge of the date of their last menstrual period, and knowledge of the antenatal care calendar were associated with coming into contact (1) with Antenatal care in the first trimester of pregnancy. In addition, there was a lack of availability of antenatal care services, inadequate reception of clients, and shortages of health products. Conclusion: There is a need to revisit strategies for communicating with women about ANC, reorganizing ANC services, and improving ANC services.

Roadside trees are effective natural solutions for mitigating climate change. Despite the usefulness of trees to carbon sequestration, there is a dearth of information on the estimation of biomass and carbon stock for roadside trees in the study area. This study aimed to estimate the carbon stock and carbon dioxide equivalent of roadside trees. A complete enumeration of trees was carried out in Kétou, Pobè and Sakété within the communes of the Plateau Department, Bénin Republic. Total height and diameter at breast height were measured from trees along the roads while individual wood density value was obtained from wood density database. The allometric method of biomass estimation was adopted for the research. The results showed that the total estimations for above-ground biomass, carbon stock and carbon equivalent from all the enumerated roadside trees were 154.53 mt, 72.63 mt and 266.55 mt, respectively. The results imply that the roadside trees contain a substantial amount of carbon stock that can contribute to climate change mitigation through carbon sequestration.

Pandé is a Congolese fermented food produced from fruit pulps of raffia palm. The aim of this study was to explore the diversities in bacterial communities in the unfermented pulps (control) (PNFL) and fermented pulps obtained from fruits using boiling (PMF) and purchased at markets in Brazzaville (PFL) and using Illumina MiSeqTM sequencing of 16S rRNA gene. A total number of 157,054 sequences was obtained and grouped into 737 operational taxonomic units (OTUs). These were classified into 13 phyla, 26 classes, 48 orders, 96 families and 176 genera. At the phylum level, the most frequent bacterial communities were: for PFM, Proteobacteria (38.94%) and Firmicutes (19.37%);for PFL, Firmicutes (69.10%) and Proteobacteria (30.89%);for PNFL, Firmicutes (84.92%) and Proteobacteria (14.22%). were the most frequent in PFL, while Acidobacteria (40.02%), Proteobacteria (38.94%) and Firmicutes (19.37%) were preponderant in PFM. Firmicutes (84.92%) and Proteobacteria (14.22%) were the most common in unfermented pulps (PNFL). Lactobacillus (47.70%) and Gluconobacter genera (15.33%) were the most represented in the PFL sample. Acidipila (35.56%) and Rhizomicrobium (11.41%) were preponderant genera in the PFM sample. Weissella genus was the most frequent in the PNFL sample. Hierarchical cluster indicated that the samples could be grouped into two groups of different origins. PCA showed that main genera were higher in the fermented samples. The diversity was higher in the fermented pulps or Pandé than in the unfermented pulps. Pandé can be a potential source for the isolation of bacteria with biotechnological potential.

Fermented foods play an important role in the daily life and diet of the populations in Congo. Among these fermented foods, there is Pilipili or fermented pepper which is consumed without prior cooking. The microorganisms present are eaten alive. Few studies have been carried out on these microorganisms which may have beneficial effects on health. This study aimed to investing taxonomic diversity of bacterial communities in 3 samples of fermented peppers produced in 3 distinct areas of Brazzaville. To do this investigation, Illumina Miseq sequencing of 16S rRNA gene was used. The results showed that the number of identified operational taxonomic units (OTUs) ranged from 156 to 392. All OTUs belong to the domain of Bacteria and could be categorized into 21 Phyla, 36 Classes, 58 Orders, 100 Families and 171 genera. Firmicutes and Proteobacteria were the main dominant phyla of the total phyla present with a relative abundance of 89.12% and 8.08%, respectly. At the class level, Bacili were dominant in EB1 (99.50%), EB3 (85.32%) and EB2 (42.29%) while Clostridia in EB2 (40.10%). Lactobacillus, Clostridium sensu stricto and Frutobacillus were the dominant genera in the sample EB1, EB2 and EB3, respectively. The hierarchical classification showed that the samples EB1 and EB2 form the same group and EB3 is unique. Principal component analysis showed that the younger EB3 and EB2 samples were more diverse than the older EB1 sample. This study is a first in Congo on the diversity of fermented pepper using Illumina Miseq. It has shown that this food is very diverse and can be a source for the isolation of bacteria with biotechnological potential.

Actually, in Republic of Congo, rhizobia have poorly phenotypically and biochemically characterized. This study aimed to characterize native rhizobia. Rhizobia strains were isolated using nodule roots collected on Milletia laurentii, Acacia spp., Albizia lebbeck, and Vigna unguiculata. The strains isolated were characterized microbiologically, biochemically, physiologically, and molecularly identified using 16S rRNA method. The results reported in this study are only for six strains of all 77 isolated: RhA1, RhAc4, RhAc15, RhAc13, RhW1, and RhV3. All native strains were positive to urease activity, negative to cellulase and pectinase activity except for one isolate that showed a positive cellulase activity. Moreover, isolates have grown at 12% of NaCl. On different effects of temperatures, isolates were able to grow up to 44°C and showed good growth at pH from 7 to 9 and the ability to use ten different carbon hydrates sources. The strains were identified as Rhizobium tropici, Rhizobium sp., Mesorhizobium sp. Bradyrhizobium yuanmingense and Bradyrhizobium elkanii
