Optimization of Cocoa Pods Maturity Classification Using Stacking and Voting with Ensemble Learning Methods in RGB and LAB Spaces.

Determining the maturity of cocoa pods early is not just about guaranteeing harvest quality and optimizing yield. It is also about efficient resource management. Rapid identification of the stage of maturity helps avoid losses linked to a premature or late harvest, improving productivity.

Dyslipidemia in Adults with Type 2 Diabetes in a Rural Community in Ganadougou, Mali: A Cross-Sectional Study.

Dyslipidemia is a disorder where abnormally lipid concentrations circulate in the bloodstream. The disorder is common in type 2 diabetics (T2D) and is linked with T2D comorbidities, particularly cardiovascular disease. Dyslipidemia in T2D is typically characterized by elevated plasma triglyceride and low high-density lipoprotein cholesterol (HDL-C) levels.

Classification of Cocoa Beans by Analyzing Spectral Measurements Using Machine Learning and Genetic Algorithm.

The quality of cocoa beans is crucial in influencing the taste, aroma, and texture of chocolate and consumer satisfaction. High-quality cocoa beans are valued on the international market, benefiting Ivorian producers. Our study uses advanced techniques to evaluate and classify cocoa beans by analyzing spectral measurements, integrating machine learning algorithms, and optimizing parameters through genetic algorithms.

CocoaMFDB: A dataset of cocoa pod maturity and families in an uncontrolled environment in Côte d'Ivoire.

Cocoa cultivation is the basis for chocolate production; it has a unique aroma that makes it useful in the production of snacks and usable for cooking or baking. The maximum harvest period of cocoa is normally once or twice a year and spread over several months, depending on the country. Determining the best harvesting period for cocoa pods plays a major role in the export process and the pods quality.

First Malian series of surgery for rheumatic valve disease: opening of the centre, clinical features and peri-operative realities.

Introduction: Over the past two decades, the incidence of acute rheumatic fever (ARF) and chronic rheumatic heart disease (RHD) have dramatically declined in wealthier regions of the world as a result of preventative programmes, improved living standards and access to cardiac surgery. Nevertheless, ARF and RHD are still public health problems in less-developed regions of the world such as Oceania, south Asia and sub-Saharan Africa.

Aim: We report on clinical, therapeutic and prognostic aspects as well as the difficulties encountered during this first series of surgery for rheumatic valve disease in Mali.

Management of delayed Sprengel malformation with intracanalar compressive omovertebral bone in a developing country's neurosurgery unit.

Sprengel deformity is a congenital abnormality done to the ascent of the scapular bone (which occurs probably between the 5th and 12th weeks of gestation). It can cause cosmetic or functional problems. The aim of our study was to describe this rare deformity, often neglected in our context, and its surgical management.

[Diagnosis and surgical traitment of intracerebral hydatic cyst in Mali].

Aims: Cerebral hydatic cysts are common in North African and pastoral countries but still underdiagnosed in sub-saharian ones.We report the first two casesoperated in Mali andhistologically proven of cerebral hydatic cysts.

Patients And Method: Our study was aboutabout a 46 years old patient, admitted for Bravais-Jacksonian crisis, dysarthry and right hemiparesy, and another 38 years old male one, with a intracranial hypertension syndrome associated with cranial fistulized cerebral hydatic cyst.

Sexual Dimorphism of Metabolomic Profile in Arterial Hypertension.

Metabolomic studies have demonstrated the existence of biological signatures in blood of patients with arterial hypertension, but no study has hitherto reported the sexual dimorphism of these signatures. We compared the plasma metabolomic profiles of 28 individuals (13 women and 15 men) with essential arterial hypertension with those of a healthy control group (18 women and 18 men), using targeted metabolomics. Among the 188 metabolites explored, 152 were accurately measured.

[Multiparametric biochemical analysis revealing an increase of homocysteinemia and NT-proBNP in hypertensive patients living in Bamako (Mali)].

Introduction: Arterial hypertension is a major public health problem in sub-Saharan Africa due to its high frequency and to the cardiovascular risk that it entails. The purpose of this study was to assess the prevalence of clinical and biological risk factors of hypertension in Bamako (Mali).

Methods: We conducted a case-control study, stratified in function of the sex, of 72 participants including 36 patients with hypertension and 36 controls.

Cardiac Pacing in Sub-Saharan Africa: JACC International.

Many parts of the developing world, especially Sub-Saharan Africa, completely lack access to cardiac pacing. The authors initiated a multinational program to implement cardiac pacing in 14 countries in Sub-Saharan Africa (1996 to 2018), aiming to eventually build self-sustainable capacity in each country. This was based on an "on-site training" approach of performing procedures locally and educating local health care teams to work within resource-limited settings, with prospective evaluation of the program.

Subclinical Cardiac Dysfunction Is Associated With Extracardiac Organ Damages.

Several studies conducted in America or Europe have described major cardiac remodeling and diastolic dysfunction in patients with sickle cell disease (SCD). We aimed at assessing cardiac involvement in SCD in sub-Saharan Africa where SCD is the most prevalent. In Cameroon, Mali and Senegal, SCD patients and healthy controls of the CADRE study underwent transthoracic echocardiography if aged ≥10 years.

Arterial Stiffness Impairment in Sickle Cell Disease Associated With Chronic Vascular Complications: The Multinational African CADRE Study.

Background: Although a blood genetic disease, sickle cell disease (SCD) leads to a chronic vasculopathy with multiple organ involvement. We assessed arterial stiffness in SCD patients and looked for associations between arterial stiffness and SCD-related vascular complications.

Methods: The CADRE (Coeur Artères et Drepanocytose, ie, Heart Arteries and Sickle Cell Disease) study prospectively recruited pediatric and adult SCD patients and healthy controls in Cameroon, Ivory Coast, Gabon, Mali, and Senegal.

Optimizing the management of acute coronary syndromes in sub-Saharan Africa: A statement from the AFRICARDIO 2015 Consensus Team.

Background: Whereas the coronary artery disease death rate has declined in high-income countries, the incidence of acute coronary syndromes (ACS) is increasing in sub-Saharan Africa, where their management remains a challenge.

Aim: To propose a consensus statement to optimize management of ACS in sub-Saharan Africa on the basis of realistic considerations.

Methods: The AFRICARDIO-2 conference (Yamoussoukro, May 2015) reviewed the ongoing features of ACS in 10 sub-Saharan countries (Benin, Burkina-Faso, Congo-Brazzaville, Guinea, Ivory Coast, Mali, Mauritania, Niger, Senegal, Togo), and analysed whether improvements in strategies and policies may be expected using readily available healthcare facilities.

The VALVAFRIC study: A registry of rheumatic heart disease in Western and Central Africa.

Background: There are few African data available on rheumatic heart disease (RHD).

Aim: To provide data on the clinical characteristics and treatment of patients with RHD hospitalized in sub-Saharan Africa.

Methods: The VALVAFRIC study is a multicentre hospital-based retrospective registry of patients with RHD hospitalized in African cardiology departments from 2004 to 2008.

Early renal damage in patients with sickle cell disease in sub-Saharan Africa: a multinational, prospective, cross-sectional study.

Background: Chronic kidney disease is one of the leading causes of mortality in patients with sickle cell disease. However, it has been almost exclusively studied in patients with the SS phenotype and in high-income countries, despite more than 80% of patients living in Africa. We looked for the determinants of glomerulopathy in a multinational cohort of patients with sickle cell disease of different phenotypes in sub-Saharan Africa.

Interdependency of subsurface carbon distribution and graphene-catalyst interaction.

The dynamics of the graphene-catalyst interaction during chemical vapor deposition are investigated using in situ, time- and depth-resolved X-ray photoelectron spectroscopy, and complementary grand canonical Monte Carlo simulations coupled to a tight-binding model. We thereby reveal the interdependency of the distribution of carbon close to the catalyst surface and the strength of the graphene-catalyst interaction. The strong interaction of epitaxial graphene with Ni(111) causes a depletion of dissolved carbon close to the catalyst surface, which prevents additional layer formation leading to a self-limiting graphene growth behavior for low exposure pressures (10(-6)-10(-3) mbar).

Usefulness of a rapid immuno-migration test for the detection of canine monocytic ehrlichiosis in Africa.

A rapid immuno-migration test for the serological detection of canine monocytic ehrlichiosis, Witness® Ehrlichia (WE) (Zoetis, France), was evaluated in 528 serum samples from dogs living in endemic areas of West and East Africa: Senegal (N=208), Ivory Coast (N=7), Sudan (N=27), and Djibouti (N=286). Of these dogs, 200 were French military working dogs (MWD) temporarily residing in Africa. The WE test results were compared with those obtained by indirect immunofluorescence (IFA).
