This study explores Arab university faculty's views on fully AI-generated assignments and research papers submitted by students, what reasons they give for their stance and how they react in this case. Surveys with a sample of 45 Arab instructors revealed that 98% do not accept AI-generated assignments and research papers from students at all. They gave numerous reasons for their position. If students submit AI-generated assignments or research papers, they would ask them to re-write them. The study recommends raising students' awareness of university policies regarding AI-generated content and introducing faculty and students to AI plagiarism detection tools. Faculty views and recommendations are reported in detail.

This study aimed to explore factors influencing students' transition from primary to secondary schools, the discrepancy of primary and secondary enrollments. The study used cluster sampling for identifying schools from the district of Assaba. The study aimed to explore the issue from teachers' perspectives. Classical Liberal Theory was adopted as a framework to guide this study. The theory argues that all individuals have the right to access education without any disparity. So, education systems are found to develop human capabilities and enable individuals to further their inherent skills. A qualitative approach was used as a study methodology, using a narrative inquiry approach to explore participants' perceptions about factors influencing the transition from primary to secondary. Interviews were the instrument used to collect data from 12 participants selected randomly from 3 schools. The study found that discontinuity of learning, home distance from schools, gender preference in education, and low income impact the transition from primary to secondary levels. The study recommends that school principals enhance counseling guidelines in schools for students, engaging parents' participation in the education process.

This study provides evidence on the distribution of school attendance and educational attainment across African countries, focusing on the correlation with literacy rates in the population, level of resources and country institutional features. The study also estimate sample correlations between enrolment and macroaggregates, related to resources (GDP per capita, student/teacher ratio), computing some counterfactuals. The authors then move to micro-data, selecting three African countries as representative examples of low (Mauritania), middle (Uganda) and high (Ghana) educational attainment. Using social surveys conducted in these countries, the authors estimate the returns to education in terms of better quality of employment (for those who are in the labour market) and of higher monetary returns (for the sub-sample of those earning a monetary wage). In addition, the authors collapse the data at household level, in order to study the determinants of individual educational attainment of children aged between 5 and 25, showing the correlation between parental education, availability of schools at community level, external shocks (like drought, famine, war) and the individual probability of being in school.

Undergraduate student dropout is gradually becoming a global problem and the 39 Small Islands Developing States (SIDS) are no exception to this trend. The purpose of this research was to develop a method that can be used for early detection of students who are at-risk of performing poorly in their undergraduate studies. A sample of 279 students participated in the study conducted in a Mauritian private tertiary academic institution. Results of regression analyses identified the variables having a significant influence on academic performance. These variables were used in a linear discriminant analysis where 74 percent of the students could be correctly classified into three categories: at-risk, pass or fail. In conclusion, this study has proposed a new technique that can be used by institutions to determine significant academic performance predictors and then identify at-risk students upon whom interventions can be implemented prior to exams to address the problem of dropouts.

The training of teachers of West Africa is carried out by the Academy of Rouen (France) and organized around an annual training plan approved by the AEFE. Each trainer only supervises twenty teachers for 5 days. Teachers from eight countries (Mauritania, Cape Verde, Senegal, Gambia, Mali, Guinea, Côte d'Ivoire and Burkina Faso), come to Dakar for a week. We have been asked four times tn Dakar (Senegal) to provide training for teachers of West Africa. It is all about being trained in order to resolve reading difficulties for students using our scientific research. This paper presents the theoretical framework of phonological awareness and letter names and the 0 phase and the beginning of Phase 1 of our research. We use these predictors as remedial reading difficulties among students aged 8 to 11 years. We present the first results.

This paper calculates a human Wellbeing Composite Index (WCI) for 42 countries, belonging to the European Economic Space, North Africa and the Middle East, as an alternative to the shortcomings of other well-known measures of socio-economic development (i.e. Gross Domestic Product per head and Human Development Index). To attain this goal, different data envelopment analysis (DEA) models are used as an aggregation tool for seven selected socio-economic variables which correspond to the following wellbeing dimensions: income per capita, environmental burden of disease, income inequality, gender gap, education, life expectancy at birth and government effectiveness. The use of DEA allows avoiding the subjectivity that would be involved in the exogenous determination of weights for the variables included in WCI. The aim is to establish a complete ranking of all countries in the sample, using a three-step process, with the last step consisting in the use of a model that combines DEA and compromise programming, and permits to obtain a set of common weights for all countries in the analysis. The results highlight the distance that still separates Southern Mediterranean countries from the benchmark levels established by some European countries, and also point to the main weaknesses in individual countries' performance. Nordic countries, plus Switzerland, top the list of best performers, while Mauritania, Libya and Syria appear at the bottom.

Different Learning Paradigms can be presented by different educators as a result of utilizing several types of Information and Communication Technologies in the Learning Process. The three abstract Learning Delivery Models are: "Traditional", "Distance", and "Hybrid Learning". Hybrid Learning attempts to maintain the best of Traditional Learning, and provides the hopes and objectives of Distance Learning in a model that maintains the "Learning Process" on the right road. Hybrid Learning shall be making use of different technologies available, exactly as does Distance Learning. Research that has focused on adopting Intelligent Technologies in Classrooms is not widely presented and deployed. Besides, the widespread of Web 2.0 resulted in the appearance of the acronym (e-Learning 2.0). E-Learning 2.0 is supposed to make use of different Web 2.0 capabilities. Web 2.0 is a big resource that changed the way everyone around thinks about and accesses the Internet, and greatly will touch the coming generations, the generations to which we are currently presenting education. This paper presents a proposed pedagogical and technical framework to empower classroom lectures with intelligent and Web 2.0 technologies that hopefully will enhance the learning process in learning institutions. Adaptive Lecture as a concept tends to help instructors providing more personalized lectures through utilizing Intelligent and Web 2.0 technologies. The growing number of students that is hardly met by the growing number of instructors is a challenge. In order not to let this challenge affect the performance of the lecture, it became important to utilize Web 2.0 technologies in the "formative assessments" within classroom. Moreover, in order to powerfully reach students, their data shall be gathered and further analyzed to make them feel more "Lecture Personalization" and get deeply "involved" with the lecture activities. Intelligent features can play an important role in achieving this task. (Contains 9 figures and 1 table.)

Background: Timely initiation of breastfeeding is crucial for positive health outcomes for babies and mothers. Understanding the factors influencing timely initiation of breastfeeding is vital for reducing child morbidities and mortalities in Mauritania. This study, therefore, assessed the prevalence of early initiation of breastfeeding and its associated factors among women in Mauritania, providing significant insights for improving maternal and child health in the country. Methods: We performed a secondary analysis of the 2019–2021 Mauritania Demographic and Health Survey data. A weighted sample of 4,114 mother-child pairs was included in the study. We used percentage to present the prevalence of early initiation of breastfeeding. A four-modelled multilevel binary logistic regression was used to examine the factors associated with early initiation of breastfeeding. The regression results were presented using adjusted odds ratio (aOR) with their respective 95% confidence interval (CI). Stata software version 17.0 was used to perform all the analyses. Results: The prevalence of early initiation of breastfeeding was 57.3% (95% CI 54.5, 60.00). Birth order was associated with early initiation of breastfeeding with the highest odds among those in the fourth birth order (aOR 1.61; 95% CI 1.08, 2.39). Mothers who practiced skin-to-skin contact were more likely to initiate breastfeeding early than those who did not (aOR 1.46; 95% CI 1.14, 1.87). There were regional disparities in the early initiation of breastfeeding. The odds of timely initiation of breastfeeding was lower among women who were delivered by caesarean section (aOR 0.22; 95%CI 0.14, 0.36), those who were working (aOR 0.57; 95% CI 0.45, 0.73), those who had four or more antenatal care visits (aOR 0.67; 95%CI 0.47, 0.94)], and those in the richest wealth quintile (aOR 0.61; 95% CI 0.38, 0.98) compared to those who had normal delivery, those who were not working, those who had zero antenatal care visits, and those in the poorest wealth quintile households, respectively. Conclusion: Our study found a relatively low prevalence of early initiation of breastfeeding among women in Mauritania. Factor such as birth order, region of residence, mother and newborn skin-to-skin contact after birth, antenatal care visits, caesarean delivery, employment status, and wealth index were associated with early initiation of breastfeeding. Improving optimal breastfeeding practices, such as early initiation of breastfeeding in Mauritania, should be given adequate attention. There is a need for interventions such as baby-friendly facilities, providing an enabling environment for mothers to breastfeed their newborns early. Addressing regional health access disparities is important to improve early initiation of breastfeeding and other maternal, newborn, and child health interventions. [ABSTRACT FROM AUTHOR]

The dromedary is a species closely linked to the culture of Mauritanian society, essential for food security, livelihood, and socio-economic development. The present study was undertaken to assess the socio-economic aspect of camel breeding in Mauritania, a typical Sahelian country. The specific objectives are to characterize the socio-demographic and zootechnical parameters of camel breeding and to evaluate its economic impact. For this purpose, an individual semi-direct questionnaire was administered to a sample of 359 breeders throughout Mauritania, who collectively keep 26,527 dromedaries. Over 72% of breeders were over 45 years old, and 70% had never received formal education. 80% of breeders had been breeding camels for over 25 years. The zootechnical performances were 2.82 L per day, 12.04 months, 11.73 months, and 23.13 months respectively for milk production, age at weaning, lactation duration, and calving-to-calving interval. Average selling prices were 13,544.24 MRU (equivalent to 342.89 $USD), 42,023.88 MRU (1,063.89 $USD), and 44,174.22 MRU (1,118.33 $USD) for young, adult females and adult males respectively. The selling age of young animals varies from 6 to 48 months, with an average of 16.17 ± 7.08 months. Pertinent indicators of economic importance were calculated, such as animal sales volume per breeder per year, job creation, annual total income per breeder, and annual total income per adult female, clearly showing the encouraging impact of camel breeding. A multifactor analysis based on productivity variables allowed us to identify 4 types of breeders, including two with a focus on dairy production and two whose primary focus is the production of live animals “Meat production”. The four types identified were “Dairy production in accessible pastoral areas”, “Dairy production around peri-urban areas”, “Meat production in remote pastoral areas” and “Meat production around peri-urban areas”. The first group consists of 164 (43.21%) farms with an average herd size of 69.90 ± 55.86 heads, generating the annual total income of 941,572.96 MRU/breeder (equivalent 23,837.22 $USD), and the annual total income per adult female of 14,790.11 MRU (375 $USD). The second group includes 73 (20.33%) farms. They have an average herd size of 74.53 ± 54.69 heads, and generate the annual total income of 976,336.15 MRU/breeder (24,717.37 $USD), and the annual total income per adult female of 15,818.68 MRU (625.50 $USD). The third group consists of 78 (21.72%) farms with an average herd size of 88.39 ± 103.8 heads. They generate the annual total income of 1,116,282.45 MRU/breeder (28,260.31 $USD), and the annual total income per adult female of 23,757.47 MRU (601.45 $USD). The tetrad group consists of 44 (12.25%) farms with an average herd size of 67.26 ± 58.93 heads, generating the annual total income of 825,592.58 MRU/breeder (20,5901.07 $USD), and the highest annual total income per adult female of 40,176.11 MRU (1,017.11 $USD). These results demonstrate the positive impact of camel breeding and can be used as a basis for any future development scenario for Mauritanian dromedaries. [ABSTRACT FROM AUTHOR]

Background: Mauritania, a lower-middle-income country in Northwest Africa, has one of the highest maternal and infant mortality rates worldwide and struggles to ensure optimal use of maternal healthcare services. Raising health awareness through family planning messages can promote maternal healthcare use, potentially reducing preventable maternal and child mortalities. The objective of the study was to assess the potential impact of exposure to family planning messages through social media on the utilization of maternal healthcare services among Mauritanian women. Methods: Data from the 2019-20 Mauritania Demographic and Health Survey (MDHS) on 7,640 women were analyzed. Multiple logistic regression models were applied to examine the associations between exposure to family planning messages through social media and maternal healthcare services, specifically the timing and adequacy of ANC visits, and facility-based childbirth. Adjusted odds ratios with 95% confidence intervals (CI) were estimated. Results: The percentage of timely initiation and adequate use of ANC among the participants were 65.6% and 45.1%, respectively. Approximately 75.0% of the women reported giving birth to their last child at a healthcare facility. Exposure to family planning messages on social media was significantly associated with increased odds of receiving adequate antenatal care visits (OR = 1.38, 95% CI = 1.12,1.71) and giving birth in a health facility (OR = 1.83, 95% CI = 1.09,3.08), Other factors such as age, health insurance, wealth, and desired timing of the last child were also found to be important predictors of maternal healthcare. Conclusion: The findings suggest that exposure to family planning messages on social media is strongly associated with adequate antenatal care and health facility-based childbirth, but not with early timing of antenatal care. Comprehensive maternal healthcare policies should consider the role of social media in promoting family planning messages. [ABSTRACT FROM AUTHOR]

Green hydrogen is becoming increasingly popular, with academics, institutions, and governments concentrating on its development, efficiency improvement, and cost reduction. The objective of the Ministry of Petroleum, Mines, and Energy is to achieve a 35% proportion of renewable energy in the overall energy composition by the year 2030, followed by a 50% commitment by 2050. This goal will be achieved through the implementation of feed-in tariffs and the integration of independent power generators. The present study focused on the economic feasibility of green hydrogen and its production process utilizing renewable energy resources on the northern coast of Mauritania. The current investigation also explored the wind potential along the northern coast of Mauritania, spanning over 600 km between Nouakchott and Nouadhibou. Wind data from masts, Lidar stations, and satellites at 10 and 80 m heights from 2022 to 2023 were used to assess wind characteristics and evaluate five turbine types for local conditions. A comprehensive techno-economic analysis was carried out at five specific sites, encompassing the measures of levelized cost of electricity (LCOE) and levelized cost of green hydrogen (LCOGH), as well as sensitivity analysis and economic performance indicators. The results showed an annual average wind speed of 7.6 m/s in Nouakchott to 9.8 m/s in Nouadhibou at 80 m. The GOLDWIND 3.0 MW model showed the highest capacity factor of 50.81% due to its low cut-in speed of 2.5 m/s and its rated wind speed of 10.5 to 11 m/s. The NORDEX 4 MW model forecasted an annual production of 21.97 GWh in Nouadhibou and 19.23 GWh in Boulanoir, with the LCOE ranging from USD 5.69 to 6.51 cents/kWh, below the local electricity tariff, and an LCOGH of USD 1.85 to 2.11 US/kg H2. Multiple economic indicators confirmed the feasibility of wind energy and green hydrogen projects in assessed sites. These results boosted the confidence of the techno-economic model, highlighting the resilience of future investments in these sustainable energy infrastructures. Mauritania's north coast has potential for wind energy, aiding green hydrogen production for energy goals. [ABSTRACT FROM AUTHOR]

Artisanal and small-scale gold mining (ASGM) is a serious growing concern in Sub-Saharan Africa. In Mauritania, recent gold discoveries in the north and northwest have led to an increase in ASGM centers, reflecting trends across the region and posing considerable risks of mercury (Hg) contamination. Notwithstanding this fact, the extent of mercury contamination in the region remains unclear due to insufficient knowledge on the mechanisms of Hg dispersion in hyper-arid regions. In light of this, the present study aimed to acquire fundamental knowledge to elucidate the dispersion mechanism of mercury through conducting soil and groundwater sampling in and around Chami town, Mauritania, where ASGM activities have intensified. We analyzed 180 soil samples and 5 groundwater samples for total mercury (total Hg) using cold vapor atomic absorption spectrometry (CVAAS) and atomic fluorescence spectrometry (AFS) methods. The total Hg levels in soil samples ranged from 0.002 to 9.3 ppm, with the highest concentrations found at ASGM sites. Groundwater samples exhibited low total Hg levels (0.25–1.25 ng/L). The total Hg content in soil and groundwater samples was below Japanese standards, yet soil samples from hotspot points exceeded other international standards. Our study emphasizes the Hg dispersion patterns around Chami town, suggesting a gradual decrease in total Hg with increasing distance from ASGM sites and a potential influence of wind dynamics. The knowledge accumulated in this study provides essential insights into the Hg dispersion mechanisms in Chami town, laying the foundation for establishing a predictive model of Hg contamination in hyper-arid regions.

Cervical cancer related to high-risk human papillomavirus (HR-HPV) is the second female cancer in Mauritania (Northwest Sahelian Africa). We assessed the distribution of HPV genotypes in Mauritanian women with high-grade cervical intraepithelial neoplasia (CIN2/3) or invasive cervical cancer (ICC). A prospective study was conducted in the Centre Hospitalier National, Nouakchott, Mauritania, to collect cervical biopsies among women suspected of CIN2/3 or cancer. HPV DNA detection and genotyping were carried out from formalin-fixed, paraffin-embedded biopsies using multiplex PCR (Human Papillomavirus Genotyping Real-Time PCR Kit, Bioperfectus Technologies Co., Taizhou, China). Fifty biopsies were included from women (mean age: 56.7 years) suffering from CIN2/3 (28.0%) and ICC (72.0%) which corresponded to 32 (64.0%) squamous cell carcinomas (SCC) and 4 (8.0%) adenocarcinomas (ADC). HPV DNA detection was successful in 47 (94.0%) samples. The most prevalent HR-HPV genotypes were HPV-45 (40.4%), HPV-16 (38.3%), HPV-39 and HPV-52 (23.4%), HPV-33 (17.0%), HPV-18 (14.9%), HPV-35 (4.2%), and HPV-56 (2.1%). The majority (93.6%) of HPV-positive biopsies contained at least one HPV type covered by the 9-valent Gardasil-9® vaccine, and 40.9% were infected by multiple vaccine HPV genotypes. To eradicate cervical cancer in Mauritania, prophylactic HPV vaccination must be combined with primary molecular screening of cervical HR-HPV infection. [ABSTRACT FROM AUTHOR]

In the Sahel, land ownership is significantly influenced by the complexity of hierarchical, ethnic, and tribal aspects as well as communal, religious, and state rights. This complicates the development of large-scale ecological projects. This study investigates the positive and negative experiences that have changed the method and attitude of agencies in Mauritania to providing a holistic and ecosystemic approach to conservation and restoration. The physical environment and society's perception of applied restoration measures are of great importance for reducing environmental degradation and promoting future actions. Interviews with stakeholders helped understand the social reality and impact of restoration and management measures taken on the communities. The results of this study revealed that measures such as fencing plots, preventing the passage of livestock, and stabilizing sand dunes noticeably improved the vegetative cover of the soil in the Sahel. This improvement in vegetation cover has had direct effects on the improvement of soil quality indicators such as organic carbon content, pH, soil structure, color, and texture. Different stakeholders have shown considerable involvement in projects, positively valuing their implementation and observing improvements in their daily lives. [ABSTRACT FROM AUTHOR]

Background: Toll-Like receptors (TLRs) play an important role in the immune response during hepatitis B virus (HBV) infection. In this study, we evaluated the association between two SNP variants (TLR3 rs3775290 and TLR4 rs4986790) and susceptibility to chronic HBV infection in Mauritania. Subjects and methods: : A total of 188 subjects were recruited for this study: 102 chronically infected patients and 86 individuals with spontaneously resolved HBV infection who were considered controls. Targeted PCR products were sequenced using Sanger sequencing. Results: We found that TLR3 rs3775290 was significantly more frequent in patients with chronic HBV than in the control population (p = 0.03). However, no association was found between the TLR4 rs3775290 polymorphism and chronic infection. Conclusion: Our results suggest that the TLR3 rs3775290 polymorphism may be a risk factor for susceptibility to chronic HBV infection in the Mauritanian population. [ABSTRACT FROM AUTHOR]

The global shift from conventional energy sources to sustainable alternatives has garnered significant attention, driven by the promise of economic benefits and environmental sustainability. The current study rigorously investigated the economic advantages and sustainability achieved from the transition of households in Mauritania from liquefied petroleum gas (LPG) to biogas utilization. The study constitutes a robust case study that centers on assessing the multifaceted impacts of this transition on household finances and overall quality of life in Mauritania. This case focuses on biogas technology adoption and its role as a competitor of LPG in Mauritania. The energy poverty portfolio of the nation has been explored and livestock waste generation and biogas production potential have been estimated at 2451 million cubic meters annually. Biogas production can fulfill 50% of the energy requirement for cooking purposes within the country. The community scale fixed-dome-type biogas digesters have been recommended for Mauritania by considering a community of 100 families. The calculated payback period for the community project is 74 months, and after the payback period, continuous monthly benefits of USD 1750 will be started. Livestock manure is directly utilized for farming practices in Mauritania, which produces 10.7 Gg of methane emissions per year. Biogas production is a clean and economically viable option for Mauritania, which can also be beneficial for reducing the methane emissions footprints of the livestock sector. This case study will prove as a vital project for other African nations if successfully implemented. Multiple recommendations for the policy-makers of Mauritania have also been formulated, like tariffs on biogas production facilities and swift financing schemes, which can further strengthen the biogas production on a national scale. International funders should also take part in coping with the energy demand of Mauritania and its mission to mitigate climate change rather than utilizing LPG on a national scale. Biogas production and utilization are much cheaper compared with the fluctuating prices of LPG and ensure health when cooking. [ABSTRACT FROM AUTHOR]

In this study, the Senegal River, being the main source of water, plays a crucial role in the area's agricultural development. Irrigation on the M'Pourie plain using water from the Senegal River is carried out without any prior sanitation control. An evaluation of the quality of irrigation water and its impact on soil salinization in different agricultural plots soil salinity is crucial for the effective utilization of traditional irrigation water over extended periods. Comprehensive physico-chemical analyses were conducted across nine locations on the M'Pourie plain in Rosso during the dynamic seasons of 2021-2023. Nevertheless, a relatively small number of studies have employed soil salinity indexing methods to examine the consequences of river irrigation on soil salinity. The analysis and interpretation of the results obtained were based both on classic methods (average and correlations) and more advanced techniques such as principal component analysis (PCA) and the Piper diagram which allow characterization and a spatial typology of water. Analysis of the Piper diagram highlights the distinction between two groups of water, weakly and moderately mineralized, ranging from 52.22 µS.cm-1 in the dry season to 72.22 µS.cm-1 in the rainy season, presenting a sodium-potassium bicarbonate facies The variability of irrigation water supplies, proves to be important in the functioning of an agro-systems. Two modes of operation have become individualized: the dry phase mode, characterized by very strong mineralization of the water linked to a significant load of dissolved elements, and the wet phase mode, whose water quality is poorly mineralized but shows the impact that its irrigation water can represent in the loading of organic and mineral pollution and the need for strict control of these waters upstream before their agricultural use. The results of this study show the absence of risks of soil salinization in relation to the chemical nature of irrigation water and the impact of agriculture on the M'Pourie plain.

The objective of this study was to conduct a preliminary assessment of the potential impacts of effluents from freezing plants and fishmeal and oil factories in the Levrier Bay on the aquatic environment through physicochemical and microbiological characterization. Effluent samples from various factories were collected and characterized by pH, dissolved oxygen (DO), electrical conductivity (EC), total dissolved solids (TDS), salinity, temperature (T°), phosphate (PO4), nitrate (NO3), nitrite (NO2), biochemical oxygen demand (BOD5), total coliforms (TC), Escherichia Coli (E.C), and fecal streptococci (FS). The concentration ranges of the effluents were as follows: pH (6.75 to 8.57), DO (1.56 to 4.66 mg/l), EC (26620 to 78520 µS/cm), TDS (13.15 to 38.70 g/l), salinity (16.26 to 49.68 PSU), T° (7.67 to 32.7 °C), PO4 (0.25 to 80.6 mg/l), NO3 (1.77 to 74.03 mg/l), NO2 (0.02 to 1.84 mg/l), and BOD5 (0.5 to 7150 mg/l). TC (2.3 x 103 to 4.6 x 106 UFC/100 ml), EC (50 to 2 x 106 CFU/100 ml), and FS (3.4 x 103 to 2.3 x 107 CFU/100 ml). The evaluated characteristics of these effluents are likely to contaminate and degrade the receiving water bodies (exceeding international standards). Hence, pretreatment of the effluent discharge is indispensable.

While the irrational use of medicines is frequently reported in sub-Saharan Africa, to the best of our knowledge no formal studies have taken place in Mauritania thus far. The main objective of this study was therefore to analyze the rational use of medicines in public and private not-for-profit health facilities, in five health districts in Mauritania.Methods: We conducted a cross-sectional study to assess the rational use of medicines. We used the standard indicators derived from the methodologies of the World Health Organization (WHO) and International Network for Rational Use of Drugs (INRUD). Data were prospectively collected from 1050 prescriptions/patients, in thirty-one public and private not-for-profit health posts/centers in 5 health districts. The data were analyzed using the Statistical Package for the Social Sciences. P value less than 0.05 at 95% confidence interval considered for significance of relationships for associations in statistical test.Results: The average number of medicines per prescription was 2.21; 83.1% (1931/2325) of medicines were prescribed by generic name, but only 54% (1253/2325) were on the National Essential Medicine List (NEML). Antibiotics were prescribed in 62.4% (655/1050) of the consultations, and injectable medicines were prescribed in 15.6% (164/1050) of the consultations. The average consultation time was 16.32 minutes, and the average dispensing time was 97 seconds. Dispensed medicines were correctly labeled, and 83% (871/1050) of patients met the correct administration schedule. The NEML, and the “restricted NEML” for 76 commonly-used medicines, were available in all surveyed health facilities, but the National Therapeutic Guidelines were available in only 60.26% of them.Conclusion: Our findings indicate a possible excess of antibiotics prescriptions, and a likely lack of knowledge of the National Therapeutic Guidelines. There is a need to investigate in more detail the prescription patterns versus disease-specific therapeutic guidelines, and to qualitatively investigate the factors that contribute to the observed irrational prescribing. Moreover, training local staff in the rational use of medicines seems important.Keywords: rational use of medicines, essential medicines, safety, antibiotics, Mauritania, sub-Saharan Africa

Abstract Background The intake of nutrient-rich foods from diverse diets ensures adequate nutrition for women. This study aims to determine dietary diversity among women of reproductive age (WRA) using the MDD-W indicator and how it relates to their socio-economic characteristics in the city of Nouakchott, Mauritania. Methods A community-based cross-sectional study was conducted on 240 women of reproductive age, aged 15–49 years. Food consumption data were obtained through unquantified 24 h recall which is designed to identify all foods consumed by the women during this period. We computed MDD-W as the consumption of at least five out of ten predefined food groups according to the guideline of the Food and Agriculture Organization (FAO) of the United Nations. In order to determine which factors had a statistically significant influence on dietary diversity among women, we used a value of P

The objective of this study was to conduct a preliminary assessment of the potential impacts of effluents from freezing plants and fishmeal and oil factories in the Levrier Bay on the aquatic environment through physicochemical and microbiological characterization. Effluent samples from various factories were collected and characterized by pH, dissolved oxygen (DO), electrical conductivity (EC), total dissolved solids (TDS), salinity, temperature (T), phosphate (PO4), nitrate (NO3), nitrite (NO2), biochemical oxygen demand (BOD5), total coliforms (TC), Escherichia coli (EC), and fecal streptococci (FS). The concentration ranges of the effluents were as follows: pH (6.75 to 8.57), DO (1.56 to 4.66 mg/l), EC (26620 to 78520 µS/cm), TDS (13.15 to 38.70 g/l), salinity (16.26 to 49.68 PSU), T (7.67 to 32.7 °C), PO4 (0.25 to 80.6 mg/l), NO3 (1.77 to 74.03 mg/l), NO2 (0.02 to 1.84 mg/l), and BOD5 (0.5 to 7150 mg/l). TC (2.3×103 to 4.6×106 CFU/100 ml), EC (50 to 2×106 CFU/100 ml), and FS (3.4×103 to 2.3×107 CFU/100 ml). The evaluated characteristics of these effluents are likely to contaminate and degrade the receiving water bodies (exceeding international standards). Hence, pretreatment of the effluent discharge is indispensable. [ABSTRACT FROM AUTHOR]

Background: The intake of nutrient-rich foods from diverse diets ensures adequate nutrition for women. This study aims to determine dietary diversity among women of reproductive age (WRA) using the MDD-W indicator and how it relates to their socio-economic characteristics in the city of Nouakchott, Mauritania. Methods: A community-based cross-sectional study was conducted on 240 women of reproductive age, aged 15–49 years. Food consumption data were obtained through unquantified 24 h recall which is designed to identify all foods consumed by the women during this period. We computed MDD-W as the consumption of at least five out of ten predefined food groups according to the guideline of the Food and Agriculture Organization (FAO) of the United Nations. In order to determine which factors had a statistically significant influence on dietary diversity among women, we used a value of P < 0.05. Results: The mean of dietary diversity was 5.48 and 71.7% of WRA had an acceptable minimum dietary diversity. During the study period, 96.25% and 80% of women consumed vitamin A and iron-rich foods respectively. The consumption rate of starchy foods, vitamin A-rich fruits and vegetables, meat, fish and chicken, milk and dairy products, dark green leafy vegetables and finally other vegetables was higher; 99.6%, 75.3%, 80%, 62.5%, 60.4% and 83.3% respectively. On the other hand, the consumption of legumes, eggs and other fruits was low; at 21.7%, 14.2% and 13.8% respectively. Conclusions: The study showed that more than half of the studied population had an acceptable minimum dietary diversity. The diet was mainly based on the consumption of starchy foods, meat and other vegetables than those rich in vitamin A. [ABSTRACT FROM AUTHOR]

Background: HIV/AIDS is one of the top global public health threats that causes significant cases, deaths, and socioeconomic impact. Even though both HIV testing and counseling are identified as essential HIV interventions during pregnancy, large population-representative data shows that service coverage and determinants are limited. Therefore, this study aimed to assess the coverage and determinants of HIV testing and counseling services among pregnant mothers attending antenatal care services in sub-Saharan African countries using different nationwide data. Methods: This study was conducted on large national-representative data from the Demographic Health Survey (DHS) using multilevel analysis. Data extraction, cleaning, coding, and statistical analysis were performed using STATA version 17. Weighting was used to ensure the representativeness of the sample and to obtain reliable estimates and standard errors. The multivariable multilevel logistic regression model was used to identify the determinants of HIV testing and counseling during the antenatal care visit. Adjusted odds ratios with 95% confidence intervals were used to measure statistical significance. Results: A total of 83,584 women attending antenatal care were included in this study. HIV testing and counseling coverage in sub-Saharan Africa was found to be 62.87% with a 95% CI of 62.54–63.19%. The HIV testing and counseling determinants included being in the age group of 35–49 (AOR = 1.64; 95% CI: 1.46–1.83), secondary and above education levels (AOR = 1.50; 95% CI: 1.39–1.60), having at least four ANC visits (AOR = 1.85; 95% CI: 1.68–2.02), living in an urban area (AOR = 1.40; 95% CI: 1.30–1.52), and living in countries such as Rwanda (AOR = 6.19; 95% CI: 5.19–7.38) and Mauritania (AOR = 0.02; 95% CI: 0.01–0.03). Conclusion: This study revealed that HIV testing and counseling coverage was 62.87% in sub-Saharan Africa. Factors affecting the HIV testing and counseling coverage were age, education, frequency of antenatal care visits, residence area, and living in Rwanda and Mauritania. Therefore, to increase HIV testing and counseling coverage in sub-Saharan Africa, policymakers on maternal health and other stakeholders should work with an integrated approach with other sectors and give prior attention to modifiable factors such as promoting women's education and the comprehensiveness of antenatal care follow-up services during the follow-up.

The rapid genetic evolution of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) during the coronavirus disease 2019 (COVID-19) pandemic has greatly challenged public health authorities worldwide, including in Mauritania. Despite the presence of the virus in Mauritania, only one study described its genomic variation during the course of the epidemic. The purpose of the present study was to document the genomic pattern of SARS-CoV-2 variants from clinical isolates during the COVID-19 outbreak in Mauritania, from September to November 2021. The whole genomes from 54 SARS-CoV-2 strains detected in nasopharyngeal swabs with a cycle threshold value ≤ 30 were successfully sequenced using next-generation sequencing (NGS) and the Illumina protocol. The mean genome coverage (±standard deviation) was 96.8% (±3.7). The most commonly identified clade was 21J (57.4%), followed by 21D (16.7%), 20A (11.1%), and 20B (9.2%). At the level of lineages, the majority of the samples were Delta variants with the sub-lineage AY.34 (or B.1.617.2.34). Among the 54 SARS-CoV-2 isolates that were successfully sequenced, 33 (61.1%) came from vaccinated individuals, and 21 (38.9%) were from unvaccinated individuals. Several SARS-CoV-2 variants were present in Mauritania between September and November 2021. As Mauritania, like many West African countries, is resource-limited regarding viral genome sequencing facilities, establishment of mutualized sub-regional sequencing platforms will be necessary to ensure continuous monitoring of mutations in viral genomes and track potential reduction in COVID-19 vaccine efficacy, increased transmissibility, and disease severity.

Objective of this study was therefore to analyze the rational use of medicines in public and private not-for-profit health facilities, in five health districts in Mauritania. Methods: We conducted a cross-sectional study to assess the rational use of medicines. We used the standard indicators derived from the methodologies of the World Health Organization (WHO) and International Network for Rational Use of Drugs (INRUD). Data were prospectively collected from 1050 prescriptions/patients, in thirty-one public and private not-for-profit health posts/centers in 5 health districts. The data were analyzed using the Statistical Package for the Social Sciences. P value less than 0.05 at 95% confidence interval considered for significance of relationships for associations in statistical test. Results: The average number of medicines per prescription was 2.21; 83.1% (1931/2325) of medicines were prescribed by generic name, but only 54% (1253/2325) were on the National Essential Medicine List (NEML).

An important factor in determining agricultural production is the availability of irrigation water in the main canal of the M'Pourie plain. This factor affects both the intensification of crops and the size of the irrigation areas. The main Senegal River canal in Rosso, Mauritania, runs across the Plaine of M'Pourie. This study aims to assess the physicochemical quality of the water used for irrigation and agriculture in the main irrigation canal on the M'Pourie plain. The measurements were made from 2021 to 2022, and the following physical and chemical parameters were monitored: pH, temperature, electrical conductivity, salt content, calcium, magnesium, sodium, and potassium; ammonium bicarbonate; chloride; nitrite; nitrate; nitrogen; sulfate; and sodium adsorption ratio (SAR). These measurements were analyzed using volumetric, spectroscopic, and spectrophotometric methods. After conducting statistical analysis and comparing the results with Moroccan quality standards for surface water utilized in irrigation, it has been discovered that the average pH value is 7.51, indicating a neutral state. However, the average nitrite and ammonium values exceed Moroccan standards at 5.16 mg.L-1 and 0.41 mg.L-1, respectively. The water's low mineralization is attributed to its low electrical conductivity, with an average of 52.2 µS.cm-1. Based on the analysis of the Senegal River water used for irrigation in the M'Pourie plain, it has been determined that its sodium adsorption ratio and electrical conductivity classify it as belonging to class C1S1. This indicates that the water has low salinity and is excellent for irrigation, with a low risk of alkalinization. [ABSTRACT FROM AUTHOR]

Abstract Background Health insurance has been documented as one of the primary methods of financing healthcare for Sustainable Development Goals (SDGs) by 2030. Yet, there is a dearth of evidence on the determinants of health insurance coverage among women in Mauritania. We examine the factors associated with health insurance coverage among women in Mauritania using a nationally representative survey dataset. Methods We analyzed secondary data from the 2019–2021 Mauritania Demographic and Health Survey. A weighted sample of 15,714 women of reproductive age (15–49 years) was included in the study. Multilevel regression analysis was used to examined the factors associated with health insurance coverage. The results were presented using an adjusted odds ratio (aOR) with a 95% confidence interval (CI). Results The coverage of health insurance among women was 8.7%. The majority of the women subscribed to social security health insurance (7.6%). Women aged 35 years and above [aOR = 1.54; 95% CI = 1.24, 1.92] were more likely to be covered by health insurance relative to those aged 15–24. The likelihood of being covered by health insurance increased with increasing level of education with the highest odds among women with higher education [aOR = 6.09; 95% CI = 3.93, 9.42]. Women in the richest wealth index households [aOR = 22.12; 95% CI = 9.52, 51.41] and those with grand parity [aOR = 2.16; 95% CI = 1.62, 2.87] had the highest odds of being covered by health insurance. Women who were working, those who watched television, and those who used the internet were more likely to be covered by health insurance relative to their counterparts who were not working, those who did not watch television, and those who did not use the internet. Women residing in Tiris zemour et Inchiri [aOR = 3.60; 95%CI = 1.60, 8.10], Tagant (aOR = 3.74; 95% CI = 1.61, 8.68], and Adrar [aOR = 2.76; 95% CI = 1.36, 5.61] regions were more likely to be covered by health insurance compared with those from Hodh Echargui. Conclusion Health insurance coverage among the women in our study was low. Achieving the SDG targets of ensuring universal health coverage and lowering maternal mortality to less than 70 deaths per 100,000 live births requires the implementation of interventions to increase health insurance coverage, taking into consideration the identified factors in the study. We recommend effective public education and awareness creation on the importance of being covered by health insurance by leveraging television and internet platforms. Also, interventions to increase health insurance coverage should consider younger women and those in rural areas.

Abstract Background Since 2014, dengue epidemics have occurred almost annually in Nouakchott, the capital city of Mauritania, coinciding with the recent establishment of Aedes aegypti, the primary vector of dengue, in the city. Anopheles arabiensis, the primary vector of malaria, is also abundant not only in Nouakchott but also in most areas of the country. Resistance to insecticides has been studied in An. arabiensis but not in Ae. aegypti in Mauritania. The objective of the present study was to establish the baseline data on the frequencies of knockdown resistance (kdr) mutations in the voltage-gated sodium channel (vgsc) gene in Ae. aegypti collected in Nouakchott to improve vector control. Methods Resting Ae. aegypti mosquitoes were collected in 2017 and 2018 in Teyarett and Dar Naim districts in Nouakchott using a battery-powered aspirator. Polymerase chain reaction (PCR) and DNA sequencing were performed to detect the presence of five kdr mutations known to be associated with pyrethroid resistance: L982W, S989P, I1011M/G, V1016G/I, and F1534C. Results A total of 100 female Ae. aegypti mosquitoes were identified among collected resting culicid fauna, of which 60% (60/100) were unfed, 12% (12/100) freshly blood-fed, and 28% (28/100) gravid. Among the mutations investigated in this study, 989P, 1016G, and 1534C were found to be widespread, with the frequencies of 0.43, 0.44, and 0.55, respectively. Mutations were not found in codons 982 and 1011. No other mutations were detected within the fragments analyzed in this study. Genotype distribution did not deviate from Hardy–Weinberg equilibrium. The most frequent co-occurring point mutation patterns among Ae. aegypti mosquitoes were the heterozygous individuals 989SP/1016VG/1534FC detected in 45.1% of mosquitoes. In addition, homozygous mutant 1534CC co-occurred simultaneously with homozygous wild type 989SS and 1016VV in 30.5% of mosquito specimens. Inversely, homozygous wild-type 1534FF co-occurred simultaneously with homozygous mutant 989PP and 1016GG in 19.5% of the mosquitoes. Conclusions To our knowledge, this is the first study reporting the presence of three point mutations in the vgsc gene of Ae. aegypti in Mauritania. The findings of the present study are alarming because they predict a high level of resistance to pyrethroid insecticides which are commonly used in vector control in the country. Therefore, further studies are urgently needed, in particular phenotypic characterization of insecticide resistance using the standardized test. Graphical Abstract
