    Introduction: Breast cancer is the most common cancer in morocco women were it occupies the first place in term of incidence and mortality. The aim of the present paper is to evaluate the risk factors associated with a breast cancer in a population of Moroccan women. Methods: A casecontrol study was conducted with population women whose age is less than 40 years during 2008-2010 at the National Institute of Oncology of Rabat. These women were interviewed for Epidemiological information and risk factor for breast cancer. Results: Included in this study were 124 cases and 148 age matched controls. No statistically significant case-control difference was found for the early age of menarche (OR = 2.474; CI 95%: 1.354- 4.521), and family antecedents of first degree of breast cancer (OR = 11.556; 95% CI: 2.548-52.411). However physical activity (OR = 0.507; 95% CI: 0.339 -0.757) early maternity age (OR = 0.212; 95% CI: 0.087 - 0.514), multiparity (OR = 0.742; 95% CI: 0.359 -1.539) and breastfeeding than 6 months (OR = 0.739; 95% CI: 0.357 -1.523) appear as significant protective factors. Conclusion: This study show the criminalization of only part of the known risk factors of breast cancer in this age group and confirms the probable protective role of physical activity and factors related to life reproductive women in our study (early childbearing, multiparity and lactation).Pan African Medical Journal 2016; 2

    The evolving SARS-CoV-2 epidemic in Africa: Insights from rapidly expanding genomic surveillance

    INTRODUCTION Investment in Africa over the past year with regard to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) sequencing has led to a massive increase in the number of sequences, which, to date, exceeds 100,000 sequences generated to track the pandemic on the continent. These sequences have profoundly affected how public health officials in Africa have navigated the COVID-19 pandemic. RATIONALE We demonstrate how the first 100,000 SARS-CoV-2 sequences from Africa have helped monitor the epidemic on the continent, how genomic surveillance expanded over the course of the pandemic, and how we adapted our sequencing methods to deal with an evolving virus. Finally, we also examine how viral lineages have spread across the continent in a phylogeographic framework to gain insights into the underlying temporal and spatial transmission dynamics for several variants of concern (VOCs). RESULTS Our results indicate that the number of countries in Africa that can sequence the virus within their own borders is growing and that this is coupled with a shorter turnaround time from the time of sampling to sequence submission. Ongoing evolution necessitated the continual updating of primer sets, and, as a result, eight primer sets were designed in tandem with viral evolution and used to ensure effective sequencing of the virus. The pandemic unfolded through multiple waves of infection that were each driven by distinct genetic lineages, with B.1-like ancestral strains associated with the first pandemic wave of infections in 2020. Successive waves on the continent were fueled by different VOCs, with Alpha and Beta cocirculating in distinct spatial patterns during the second wave and Delta and Omicron affecting the whole continent during the third and fourth waves, respectively. Phylogeographic reconstruction points toward distinct differences in viral importation and exportation patterns associated with the Alpha, Beta, Delta, and Omicron variants and subvariants, when considering both Africa versus the rest of the world and viral dissemination within the continent. Our epidemiological and phylogenetic inferences therefore underscore the heterogeneous nature of the pandemic on the continent and highlight key insights and challenges, for instance, recognizing the limitations of low testing proportions. We also highlight the early warning capacity that genomic surveillance in Africa has had for the rest of the world with the detection of new lineages and variants, the most recent being the characterization of various Omicron subvariants. CONCLUSION Sustained investment for diagnostics and genomic surveillance in Africa is needed as the virus continues to evolve. This is important not only to help combat SARS-CoV-2 on the continent but also because it can be used as a platform to help address the many emerging and reemerging infectious disease threats in Africa. In particular, capacity building for local sequencing within countries or within the continent should be prioritized because this is generally associated with shorter turnaround times, providing the most benefit to local public health authorities tasked with pandemic response and mitigation and allowing for the fastest reaction to localized outbreaks. These investments are crucial for pandemic preparedness and response and will serve the health of the continent well into the 21st century

    International audienceChlamydospores of Fusarium oxysporum f.sp. albedinis are well known as fungus survival spores in soil, also act as a causal agent of Bayoud disease of the date palm. Till now, there are a little study in the literature about the favorable media for the formation of chlamydospores and the stages of chlamydogenesis. This study shows that rice flour based medium (45 chlamydospores per mm 2), oatmeal (31 chlamydospores per mm 2) and bean flour (27 chlamydospores per mm 2) tested for the first time, are among the media inducing the formation of chlamydospores in large numbers. The optimum formation of chlamydospores is observed on rice flour-based medium after 7 days of Original Research Article Smail et al.; ARRB, 18(4): 1-9, 2017; Article no.ARRB.35653 2 incubation at 18°C and pH 7. The effect of light does not seem very important on chlamydogenesis. However, relative humidity has a significant effect on the growth and chlamydogenesis of F. oxysporum f.sp. albedinis. The tested G 1 isolate grows and forms chlamydospores at relative humidities of 70 and 100%. The number of chlamydospores varies between 40.01 and 44.05 chlamydospores/mm 2. To form chlamydospores, cultures of F. oxysporum f.sp. albedinis need to be in contact with the favorable culture medium. Thus, the cultures develop and form more chlamydospores on a single layer of cellophane deposited on a culture medium, but show slower growth and do not form chlamydospores on two layers of cellophane. Chlamydospores of Fusarium oxysporum f.sp. albedinis are always at the extremity of the mycelial filaments. They differ in one to four cells in superimposed position. A terminal hyphal bulge leads to the formation of the terminal cell. The second cell is formed at the base of the first, and the process continues so that one can sometimes observed chlamydospores in bead-like chains

    Good nutrition plays an essential role in our health. It decreases the risk of developing certain chronic diseases and thus increases life expectancy. This study is the first of its kind in Morocco, its objective is to determine the nutrient composition of the most consumed Moroccan culinary recipes. Thus, thanks to the calculation of the nutriscore, we can know which culinary recipe is the “healthiest”. Some of the most consumed Moroccan traditional dishes were collected in which carbohydrates, fats, and proteins were analyzed using the procedures of the Association of Official Analytical Chemists, then followed by a calculation of the food exchange lists per serving using the Wheeler method. Variations in macronutrients, micronutrients (minerals and trace elements) and trans-fatty acid content, polyunsaturated and monounsaturated were found among the Moroccan dishes. The highest protein (17.37g/100g) in Chicken, French Fries, and Cumin Tajine while the lowest (0.06g/100g) in Orange and Carrot Salad. The highest carbohydrates (42.68g / 100g) in Tuna Pizza while lowest (2.37g / 100g) in tomato with pepper. And the highest lipids (19.2g/ 100 g) in meat with onion Tajine and the lowest (0.6g/ 100g) in Harira. Meanwhile, the energy ranged between 35.7 and 352.4 Kcal/100 g in the dishes. For each dish and according to the size of each serving, the exchanges of carbohydrates (starch), fats, and proteins (lean meat, medium fat, and high-fat meat) were calculated. This study offers an opportunity - for health professionals, dietitians as well as consumers - to orchestrate with knowledge traditional dishes and ensuring leading dietary and medical nutritional therapy practices and patient self-control
