The study addressed a crucial public health concern of dyslipidemia and its management, with a focus on the Ignace DEEN National Hospital patients, filling a research gap in the Republic of Guinea. It contributed valuable epidemiological data on dyslipidemia in the studied population, emphasizing gender, age, and socio-professional categories, which could inform tailored prevention and management strategies in improving the health care of dyslipidemia patients by proposing diets to help these patients better manage their disease and a food system for preventing dyslipidemia. The study focused on the lipid profile of patients seen at the cardiology department at the Ignace DEEN National Hospital Republic of Guinea (Conakry). This was a prospective, descriptive study lasting six (6) months from January 24 to July 23, 2021;aimed at determining the frequency of lipid abnormalities and pathologies related to the lipid profile. A total of 523 people were included in this study with a female predominance of 59.34% compared to 40.66% of males for a ratio of 1.5 in favor of women. The age groups of 45 - 54 and 55 - 65 were the most affected with respective frequencies of 45.42% and 30.03%. The most represented socio-professional category was that of housewives, i.e. 45.78%, followed by traders 18.68%. Our series was dominated by the married couple, i.e. 77.29%. Dyslipidemia constitutes a modifiable cardiovascular risk factor in patients seen in the cardiology department at the Ignace DEEN Hospital;its control must be strict through the use of hygienic and dietary rules and hypolipidemia medications.

Mango Diseases Classification Solutions Using Machine Learning or Deep Learning: A Review

引用

Journal of Computer and Communications 2022年第12期10卷 16-28页

作者： demba Faye Idy Diop Doudou Dione Cheikh Anta DIOP University of Dakar Dakar Senegal

The mango crop suffers from several diseases that reduce both the production and the quality of the mangoes. This also reduces its price on the international market. Diagnosis of these diseases remains difficult in many countries due to poverty and lack of infrastructure. Plant pathologists use several techniques to identify these diseases. But these techniques are time consuming and relatively expensive for mango growers and the solutions proposed are often not very accurate and sometimes biased. In the last decade, researchers have proposed several solutions in the field of automatic diagnosis of mango diseases. Such solutions are based on Machine Learning (ML) and Deep Learning (DL) algorithms. In this paper, we divided these solutions into two groups: solutions based on classical ML algorithms, and those based on DL. In recent years, DL, especially Convolutional Neural Network (CNN) has become the most widely used method by researchers because of its impressive performance. The critical analysis of the proposed solutions has allowed us to identify their limits and potential challenges in mango disease automatic diagnosis.

马里是一个位于西非的内陆国家,人口1900万,由两个地理区域组成。90%的人口集中在南部首都巴马科附近,主要由黑人民族组成。该国北部地区人口由阿拉伯人和大部分游牧民族的图阿雷格人组成,该地区位于该国的边境,甚至存在武器和毒品,以及难以控制极端主义团体,因为他们找到了庇护所。本研究旨在研究国际社会在解决马里2013年政治和安全危机中的作用。为此,本论文通过冲突解决理论以及维和机制分析国际社会在马里危机过程中的角色和作用。正文分为三章:第一章利比亚政权垮台的危机引发了新的武器交易产生以及卡扎菲雇用一些图阿雷格人,雇佣军回流给马里带来了巨大的挑战。2012年3月22日,军方夺取政权,很快就控制了一些领土。根据该地区的伊斯兰教法,这一举动破坏了位于廷巴克图的联合国教科文组织世界遗产。伊斯兰北方对巴马科萨赫勒地区的脆弱性颇为敏感,那里有受到马里难民及其恐怖主义影响的邻国,比如布基纳法索,毛里塔尼亚,尼日尔。第二章从不同维度分析了联合国对马里危机的介入。联合国安理会就马里问题发布了若干决议,国际社会将参与马里的局势。同样,马里总统寻求法国政府的援助,以镇压来自北方的反叛分子或恐怖组织。总的来说,法国通过联合国决议和A.U以及马里总统的要求,共同努力让国际社会参与解决马里的安全和政治危机。事实证明,这场危机难以通过谈判得到解决,因为叛乱分子和恐怖分子团体的要求无法与巴马科中央政府的要求相协调,正是这种僵局使军事手段成为解决冲突的唯一可行选择。为此,法国政府通过提供财政、后勤和军事干预(serval)来实现。第三章聚焦于非洲联盟(A.U)等组织参与解决马里危机。非盟将此事提交给西非国家经济共同体(西非经共体)以解决危机。然而,由于财政和技术方面的挑战,非盟在解决冲突方面做得不够。此外,法国军队和马里稳定团与马里军队合作,成功地压制了叛乱。本研究建议,为了使国际社会在危机干预中发挥有效作用,需要进行适当的规划,以便迅速应对像马里这样的危机。

Atmospheric and Climate Sciences 2020年第2期10卷 206-219页

This study aims to evaluate dust impact on climate parameters over the Sahel region by RegCM3 regional model during 2006. Indeed, aerosols are one of the main uncertainties in climate models. The aerosol optical depth (AOD) derived from RegCM3 model has been validated with various observed datasets. The aerosol sources are identified over North Algeria and East of Sahel (Bodele depression). Discrepancies are noted when considering dust temporal and spatial distribution. Dust season extends between March and October, with two peaks of AOD recorded in March (spring) and June (summer). The dust vertical distribution showed that the mineral aerosol layer is located between 850 hPa and 300 hPa (1.5 km to 7 km). The RegCM3 model simulates fairly well the transport in the upper layers, especially in the Saharan Air Layer (SAL) during the summer. However, RegCM3 simulates poorly the transport and sedimentation of particles in the lower layers (below 2 km). The investigation of dust radiative impact shows a general cooling. The maximum of radiative forcing is located around 18°N - 20°N, with values of about -80 W/m2 in June - August (JJA) and -40 W/m2 at the surface during March - May (MAM). This study also showed the indirect effect of dust with a decrease in precipitation about -0.7 mm/day around 15 - 20°N during the rainy season.

Journal of Computer and Communications 2023年第9期11卷 57-75页

作者： demba Faye Idy Diop Nalla Mbaye Doudou Dione Marius Mintu Diedhiou Polytechnic School of Dakar University Cheikh Anta Diop Dakar Senegal Department of Plant Biology Faculty of Science and Technology University Cheikh Anta Diop Dakar Senegal

The world’s agricultural production suffers huge losses estimated between 20% and 40% annually. 40% to 50% of such losses are due to pest and diseases which cause significant economic losses every year. Precise assessment of severity is crucial for suitable management of crop diseases. It helps famers to avoid yield losses, reduce production costs, ensure good disease management and so on. This paper is a review of plant diseases severity estimation solutions proposed by researchers the last few years and based on Image Processing Techniques (IPT), classical Machine Learning (ML) and Deep Learning (DL) algorithms. The analysis of these solutions has allowed us to identify their limitations and potential challenges in plant disease severity assessment.

河流流量估算是水文学家普遍采用的一种活动,它考虑了几个气象因素。虽然有些方法需要彻底了解水文过程以及导致径流的不同参数之间的关系,但其他方法并不需要它。该研究工作主要提出了一种基于特定类型的人工神经网络的方法,称为长期短期记忆(LSTM)来预测泾河流量。本文借助LSTM的时间依赖建立了预测模型。该模型将根据前一天的流量和天气条件预测每天的河流流量。模型的性能高度依赖于超参数值。为了找到超参数的最佳组合,使用随机搜索方法,即,测试随机超参数的组合,直到实现最佳可能的参数。然后将建立的模型与GWLF(广义流域加载函数)的分水岭模型进行比较。由于GWLF使用月值,每日观察和预测的流量被转换为月总流量,以便能够比较性能。使用两个性能指标RMSE和NSE系数作为评价性能的依据,实际运行表明本文提出的LSTM模型在校准和验证期间都优于GWLF。

Open Journal of Pediatrics 2023年第6期13卷 763-773页

作者： Guillaye Diagne Papa Souleye Sow Khadim Bop Maimouna Sow Idrissa demba Ba Albert Royer National Children’s Hospital Dakar Senegal

Acute chest syndrome (ACS) is a serious pulmonary complication of sickle cell disease. It is estimated to be responsible for a quarter of deaths in the pediatric sickle cell population. In Senegal, there are not enough pediatric studies in this area. The objective of our study was to determine the epidemiological, diagnostic and evolutionary characteristics of ATS at the Albert Royer National Children’s Hospital (CHNEAR) in Dakar. This was a retrospective study in patients hospitalized at CHNEAR for ATS from January 1, 2021 to March 31, 2022. We included patients hospitalized and diagnosed with ATS. We had collected 102 patients, i.e. a hospital incidence of 2.96%. The average age of the children was 9 years old;the sex ratio was 1.04. The main symptoms on admission were hypoxemia (97.06%), chest pain (77.45%), dyspnea (77.45%) and fever (65.69%). 52.94% of patients had an associated vaso-occlusive crisis (VOC). The chest x-ray was abnormal in 92 patients, a rate of 90.20% and showed images of pneumonia (71%);bronchitis (17.65%) and pleurisy (0.98%). None of the children benefited from a pulmonary ultrasound. The treatment associated with analgesics (100%), broad-spectrum antibiotics (100%), oxygen therapy (100%), hydration (95.09%), transfusion (73.53%), non-ventilation invasive (6.86%), intubation (2.94%) and beta 2 mimetics (12.75%). No patient benefited from incentive spirometry. Almost all of the patients 95.10% (n = 97) had a favorable clinical evolution. However, five children (4.90%) had an unfavorable outcome including one case of complication such as stroke (0.98%) and four (4) cases of death. The average hospital stay was 8 days. ATS is common in children with sickle cell disease in Senegal and its etiologies seem to be dominated by infectious causes in our context.

Epidemiological Profile of Men Who Have Sex with Men: First Data about Male Sex Workers in Central African Republic (CAR)

引用

Advances in Sexual Medicine 2024年第1期14卷 1-11页

作者： Hermione Dahlia Mossoro-Kpinde Balekouzou Augustin Paola Julienne demba Henri Saint Calvaire Diemer Direction de la Médecine du Travail Ministère du Travail de l’Emploi de la Protection Sociale et de la Formation Professionnelle Ban-gui République Centrafricaine Comité National de Lutte contre le Sida Bangui République Centrafricaine Faculté des Sciences de la Santé Université de Bangui Bangui République Centrafricaine Département de Santé Publique Faculté des Sciences de la Santé Université de Bangui Bangui République Centrafricaine

Objectives: Sex work is not well documented among African men. The aim of this study was to describe the epidemiological profile of men who have sex with men (MSM) and eventually to determine the proportion of sex workers (SW) among them, as well as the proportion of MSM who have been victims of gender-based violence (GBV). Material and Methods: A cross-sectional study coordinated by the Direction de la Médecine du Travail was carried out at the headquarters of the association ALTERNATIVES in Bangui Bangui from July 1 to October 31, 2021. Consenting MSM present during the study period were systematically included. Sociodemographic variables, those relating to the future vision of the activity and to GBV were collected and analyzed using Epi-Info version 7 software. Results: Forty MSM with an average age of 23 years and mainly secondary education (75.0%) were included. The vast majority of MSM were unemployed (85.0%). 45.0% had been victims of GBV and wanted to stop working as an MSM (47.5%), and almost 2/3 (65.0%) would accept another income-generating activity in exchange for the MSM. Violence was sexual (32.5%), economic (22.5%), physical (20.0%), verbal (12.5%) and psychological (12.5%). Conclusion: The MSM were mainly young, poorly educated, unemployed, and almost half were victims of GBV. The desire to change MSM activity to another income-generating activity alongside that of MSM shows that many of them are SW, workers in the informal sector. This must be taken into account in prevention activities, even if the data needs to be confirmed on a much larger sample.
