Contribution of GIS to Soil Landscape Mapping by Multi-Criteria Analysis Using Weighting: The Case of the Square Degrees of M’Bahiakro (Centre) and Daloa (Centre-West) in Ivory Coast

As part of the drive to improve coffee and cocoa production in Ivory Coast, studies are carried out to identify soils that are favourable for these crops. It is therefore necessary to orientate soil investigations based on reliable criteria that best discriminate soil cover. With this in mind, this study is being carried out to help improve survey methods by mapping soil landscapes. It uses GIS and weighted multicriteria analysis. To do this, satellite images were processed and the geological map of the square degrees of M’Bahiakro and Daloa was reclassified. The results show that relief is the main factor in soil landscape differentiation, with respective weights of 0.58 and 0.67 for the forest and pre-forest zones. In contrast, the weight of geological formation in soil landscape differentiation remains low (0.05 for the forest zone and 0.07 for the pre-forest zone). The criteria used on the base of aggregation sum methods have made it possible to formulate soil landscape mapping prediction functions according to agro-ecological environments in the humid intertropical zone. This is essential for the orientation of soil survey work. Nevertheless, other comparative methods, such as the coding mapping method, could provide elements for discussion to validate the models.

Technical-Economic Performance, Carcass and Meat Quality of COBB500 Broilers Fed Rations Incorporating Mango By-Product Feeds in Ivory Coast (West Africa)

The study evaluated the growth performance and carcass quality of COBB500 broilers fed two experimental rations incorporating feed and mango fine ED10 for a batch of 83 birds, ED20 (batch of 83 birds) in comparison with a commercial control ration CCD (84 birds). For this purpose, 250 day-old chicks of this breed were purchased in Korhogo and transported to Tengréla in Ivory Coast for rearing. The results show that substituting mango provender ans and mango seed flour for maize resulted in rations with costs per kgMS of 215.35FCFA, 2016.93FCFA and 320FCFA for the ED10, ED20 and CCD rations respectively. The production costs per kg of chicken (FCPkgLW) of the CCD ration were significantly higher than those of the ED10 and ED20 (p 0.05). ADGs were significantly different and decreasing from CCD, ED20 to ED10 (p 0.05). Average weights at 42nd day for ED20 and CCD were homogeneous (p > 0.05) and significantly higher than for ED10 (p 0.05). By day 49th the average weight of ED20 had reached and exceeded that of CCD by day 42nd. PSLW, HCW and CCW were significantly different and decreasing from CCW, ED20 to ED10 (p 0.05). Average hot (HCY) and cooled (CCY) carcass yields of ED20 and CCD rations were comparable (p > 0.05) and significantly higher than those of ED10 ration (p = 0.009) and 0.003). Average drumstick and neck weights were significantly higher and lower for CCD, ED20 and ED10 (p 0.05). For all other parts of the cut, the average weights of the CCD ration were significantly higher (p 0.05) than those of the ED20 and ED10 rations, which were homogeneous (p 0.05). The incorporation of mango provender and mango seed flour in broiler rations offers the prospect of reduced production costs, less competition between man and animals over cereals, and lean meat production that is more appreciated than that of chickens fed conventional feed. As it stands, the ED20 ration can be recommended as a growth diet for broilers. It would be necessary to determine the levels of anti-nutritional substances in mango feeds and to assess the in vivo digestibility of mango ingredients and the diets incorporating them.

Management of Mandibular Fractures in Children in Ivory Coast: Experience of the Stomatology and Maxillofacial Surgery Department at the University Hospital of Cocody from 2000 to 2019

Introduction: Mandibular fractures in children are becoming increasingly common. Treatment of these fractures is difficult due to their anatomical and physiological complexity. Therefore, there is a need for well-codified management. Our main aim was to develop a decision algorithm for the management of mandibular fractures in children based on our experience. Materials and Methods: This was a retrospective descriptive study carried out in the Department of Stomatology and Maxillofacial Surgery at the University Hospital of Cocody over a period of 20 years (2000-2019). Results: We enrolled 58 patients. The mean age of the patients was 9.35 ± 2.3 years with a sex ratio of 2.22. Traffic accidents were the main cause of mandibular fractures (60.35%). Condylar fractures were the most common (46.87%). Treatment was orthopedic in 45.76% of cases, mixed (orthopedic and surgical) in 24.14% and surgical in 5.17%. Patients were followed up weekly for 1 month, then monthly for 6 months and annually for 3 years, with panoramic radiographs of the maxilla starting at 21 days. We observed 2 cases of complications: temporomandibular ankylosis and gingival stomatitis. Conclusion: Mandibular fractures are common in children. Management is difficult due to anatomical and physiological peculiarities. The choice of treatment depends on several criteria.

Response of the Maize Variety EV87-28 to a Fertilization Strategy Involving Indorama Granular Urea on Ferralsol in the Central Ivory Coast

In Côte d’Ivoire, the decline in soil fertility strongly impacts the productivity of maize (Zea mays L.) on heavily leached ferralitic soil. In this study, the general objective was therefore to improve the productivity of maize EV87-28 on the Ferralsols in pre-forested areas during different cropping seasons. Eight (8) micro-plots were set up according to a total randomization device with three repetitions. Two factors were studied: nitrogen fertilizer modalities (main factor) and crop season (secondary factor). Growth, flowering and yield parameters were measured and analyzed. The results showed that there was no interaction between the nitrogen fertilizer factor and the cropping season factor. In addition, this study showed the short rainy season had the most positive impact on growth, flowering and yield parameters than the long rainy season. The results also showed that the different nitrogen fertilizer modalities had no statistically different effects on growth, flowering and yield parameters. However, quantitative differences were reported, highlighting one nitrogen fertilizer modality, which is the combination of urea granule + farm manure (75% urea indorama granules and 25% farm manure). The combination of urea granule + farm manure (75% urea indorama granules and 25% farm manure) had the best effect on corn grain yield. So, the combination of urea (75%) and manure (25%), that resulted in yield gain, could be recommended for corn fertilization during the small rainy season.

Micropenis Associated or Not with Cryptorchidism in the Endocrinology Department of Yopougon University Hospital in Ivory Coast: Epidemiological, Clinical, Paraclinical and Therapeutic Aspects

Background: Congenital malformations such as micropenis and cryptorchidism do not have immediate dramatic consequences. However, the diagnosis is often unknown at birth, and therefore late. In Ivory Coast, there are few studies on cryptorchidism and micropenis. We conducted this study to identify the epidemiological, clinical, etiological and therapeutic characteristics of the micropenis associated or not with cryptorchidism at Yopougon University Hospital. Methods: We conducted a retrospective descriptive study in the Department of Endocrinology-Diabetology of the Yopougon University Hospital carried out over 13 years from January 2005 to December 2018. All patients were included regardless of the presence of a micropenis associated or not with cryptorchidism in the clinical or paraclinical examination. Results: A total of 14 micropenis were reported associated in 6 cases with cryptorchidism. It was unilateral cryptorchidism in 4 patients or 66.66% of cases. The average age of affected patients was 21.32 years with extremes ranging from 10 months to 48 years. The reason for consultation was micropenis in 12 out of 14 cases or 85.75%. The associated signs apart from cryptorchidism were obesity in 42.86% of cases, gynecomastia in 35.71% of cases. The aetiology was dominated by idiopathic causes. Treatment with testosterone enanthate was more effective in pre-pubertal children than in adults. Conclusion: The diagnosis of micropenis associated or not with cryptorchidism is late because of the frustrations, taboos and psycho-social states that it causes. However, drug treatment is effective when treatment is started early.

Analysis of the Quality of Physical and Chemical Parameters of Groundwater in Three Localities in the Sub-Prefecture of Zanzra (Ivory Coast)

The availability of groundwater of acceptable quality has become a difficult challenge to meet in many countries, particularly Côte d’Ivoire. The State of Côte d’Ivoire and rural populations are building hydraulic infrastructure for this purpose. However, the quality of water coming from these infrastructures remains to be determined. This study therefore aims to analyze certain physicochemical parameters of the groundwater of Gloazra, Kouezra and Trahonfla. These are temperature, pH, electrical conductivity, TDS, salinity level, hardness, alkalinity, chloride content and bicarbonate. To determine the pH, electrical conductivity, temperature, TDS, and salinity rate, an electrochemical analysis was carried out. The titrimetric analysis made it possible to determine the chloride and bicarbonate content, alkalinity, and hardness. The results indicate that the studied groundwater is soft and acidic with good mineralization. This water does not present a health hazard to consumers but can affect hydraulic equipment and household containers.

Calcium-Magnesium Ca/Mg Ratios and Their Agronomic Implications for the Optimization of Phosphate Fertilization in Rainfed Rice Farming on Acidic Ferralsol in the Forest Zone of Ivory Coast

This study is a contribution to improving rice productivity on acidic plateau soils of the tropical rainforest zone. It is based on taking into account the cationic balances of the soil in order to optimize the phosphorus (P) nutrition of rice on these acidic soils, where this nutrient constitutes a limiting factor for agricultural production. Three (3) pot trials were conducted in Adiopodoumé in the forested south of Côte d’Ivoire. The interactive effects of calcium carbonate (0, 25, 50 and 75 kg Ca ha−1) and magnesium sulfate (0, 25, 50 and 75 kg Mg ha−1) were evaluated on the response of NERICA 5 rice at doses 0, 25, 50 and 75 kg P ha−1 of natural phosphate from Togo, applied only once at the start of the experiment. Additional fertilizers of nitrogen (N) (100 kg N ha−1) and potassium (K) (50 kg KCl ha−1) were added to each of the tests in a split-plot device. The test results revealed a paddy production potential of approximately 3 to 5 t⋅ha−1 for NERICA 5 on an acidic soil, under the effect of the interaction of P, Ca and Mg. The quadratic response of rice yield to the doses of these fertilizers would be more dependent on their balance, itself influenced by Ca nutrition. For the sustainability and maintenance of rice production in agro-ecology studied, it was recommended doses of 38 kg Ca ha−1, 34 kg Mg ha−1 in a Ca/Mg ratio (1/1) with intakes of 41 kg P ha−1, overall in a ratio 1/1/1 (P/Ca/Mg) more favorable to the availability of free iron considered a guiding element of mineral nutrition. Thus, these promising results should be confirmed in a real environment for better management of the fertilization of rice cultivated on acidic plateau soils in Côte d’Ivoire.

One Case of Acute Fluid Pericarditis and Hyperthyroidism at Teaching Hospital of Bouake (Ivory Coast): Cause-Effect Relationship or Accidental Association?

Cardiovascular complications during hyperthyroidism are dominated by arrhythmias, heart failure and coronary heart disease. Pericardial effusion which is a common complication of hypothyroidism is extremely rare in hyperthyroidism. We report the case of a 45-year-old woman admitted for management of pleuro-pericarditis associated with atrial fibrillation in the context of cardiothyreosis. The treatment consisted of a pericardial puncture associated with synthetic anti-thyroid drugs and anti-tuberculosis drugs with positive clinical and echocardiographic outcomes.

Prevalence and Factors Associated with Intestinal Metaplasia in Chronic Helicobacter pylori Gastritis in a Country with High Endemicity: Ivory Coast Case

Context/Objective: Few studies have been carried out in a country with high endemicity for Helicobacter pylori (H. pylori) infection in Sub-Saharan Africa looking for the association of intestinal metaplasia (IM) with chronic gastritis. We hypothesize that IM is correlated with the intensity of H. pylori infection in a country with high endemicity, Ivory Coast. The objective of this study was to determine the prevalence of intestinal metaplasia in chronic H. pylori gastritis in Ivory Coast. Methods: This was a prospective, cross-sectional, multicenter study, carried out over a period of 5 months, in the reference hospital centers of Abidjan, specialized in Gastroenterology. All patients who had undergone Gastroscopy with biopsies according to the criteria of the Sydney System for the anatomopathological study, those with chronic gastritis and/or H. pylori intestinal metaplasia on histology and in whom all the parameters of the Sydney system classification had been well informed. The quantitative variables were expressed by their means accompanied by their standard deviations and the qualitative variables by their numbers and percentages. Chi-square and Fischer tests were used to look for associations between variables. The significance level was set at 5%. Results: 152 patients were retained. The mean age was 44.9 ± 12.9 years. The prevalence of intestinal metaplasia was 11.8%. In univariate analysis, no significant association was found between clinical and pathological sociodemographic factors (age, sex, ethnicity, educational level, profession) and intestinal metaplasia in chronic Helicobacter pylori gastric cases. In multivariate analysis we found that prolonged use of Proton Pump Inhibitors (PPIs) and a history of Gastroesophageal Reflux Disease (GERD) were significantly associated with the absence of IM. Conclusion: Chronic H. pylori gastritis is the main risk factor for intestinal metaplasia. Prolonged use of PPIs and a history of GERD were significantly identified as factors that would protect against intestinal metaplasia.

Impact of Climate Variability on Water Resources: The Case of Marc Delorme-Cnra Station, Southeast of Ivory Coast

This study aims to characterize the climatic variability in the South-East of Ivory Coast and to show its impact on the supply of water resources. To do this, statistical and hydrological methods were applied to climatic data collected at the Marc DELORME Research Station of the CNRA. The statistical trend tests on this data revealed a significant decrease in precipitation and an increase in temperature, insolation and evaporation. Statistical break methods indicate a rainfall break in 1982 which marks a modification of the rainfall regime thus translating a drop in rainfall of 15%, a recession in the frequency of rainy days in general and in particular in rainfall heights between 10 and 30 mm and greater than 50 mm. This break is accompanied by a shortening of the rainy seasons, with average rainfall durations ranging from 54 days (short rainy season) to 104 days (great rainy season). Despite the disturbances in the different seasons of the year, the monthly rainfall regimes in the area have not changed. The assessment of the effects of drought on water resources using the Standardized Precipitation and Evapotranspiration Index (SPEI) for three-time scales (1 month, 3 months and 12 months) indicates a severe drought ranging from 3% to 7% over the period 1961 to 2018. However, despite the presence of this severe drought, the intensity of the drought was found to be moderate on all time scales. The Thorrnthwaite method was used to highlight the impacts of this climatic variability on the region’s water resources. The average annual recharge estimated at 402 mm, has been reduced to 153 mm during a deficit period, a decrease of about 62%. The average annual runoff, which was 294 mm, fells to 257 mm, a decrease of about 13%. This recorded decrease in the water infiltrated after the rainfall break (1983-2018), explains the heterogeneous decrease in the depth of the water table.

Pancreatic Cancer: Epidemiological, Clinical and Therapeutic Aspects in Abidjan (Ivory Coast)

Aim: The aim was to study the epidemiological, clinical and therapeutic aspects of pancreatic cancers in Ivory Coast. Materials and methods: A retrospective multi-center and multidisciplinary study aimed at describing sixteen years and four months from January 1, 2000 to April 30, 2016 in several hospitals in the city of Abidjan taking charge of pancreatic cancers (hepato-gas troenterology services of the universities hospitals of Cocody and Yopougon), internal medicine departments of University Hospital of Treichville and Abidjan Military Hospital, the department of oncology of the university hospital center of Treichville, private clinics (DANGA, PISAM and GMP), the COBA center in Treichville. The diagnosis of cancer was based on either histological criteria or a set of clinical and paraclinical arguments. Patients whose files did not include imaging were excluded from this study. The following parameters were collected: age, sex, reason for consultation, physical signs, personal and family antecedents, tumor characteristics, delay in diagnosis and the nature of the treatment administered. Results: We have observed 150 cases of pancreatic cancer. The mean age of patients was 59.09 years with extremes ranging from 24 years to 88 years. Our study population consisted of 98 men and 52 women (sex ratio 1.88). Risk factors were dominated by diabetes 20.7%. Epigastralgia is the main reason for consultation (48%). The tumor was localized at the cephalic level in 84.67%. In 13 cases the diagnosis was histological and was dominated by adenocarcinoma (100%). The majority of our patients was seen at an advanced stage of the disease: stage IV (74.56%). The average time to diagnosis was 2.76 months. Fourteen of our patients (9.33%) had benefited surgery. This was curative surgery in 35.71% (n = 5) and palliative in 64.29% (n = 9). Among those who benefited from this curative surgery, three died two months after surgery and two lost to follow-up. The majority (90.67%) of our patients had received symptomatic treatment. Conclusion: Pancreatic cancer is an appalling cancer with a very bad and late diagnosis because of its insidious symptomatology. Most of the time, tumors had already metastasized before diagnosis, so the treatment is often symptomatic.

Doppler Ultrasound Abnormalities of the Lower Limbs in Patients with Diabetic Foot at the Yopougon University Hospital in Ivory Coast

Background: Diabetic foot is a frequent complication of diabetes, of multifactorial origin, associating nervous and/or circulatory disorders to which infection is often added. Its care is multidisciplinary and requires coordination between different actors. In this context, arterial doppler ultrasound is essential in the diagnosis of diabetic arteriopathy and participates in therapeutic decision-making. The aim of this study was to describe the abnormalities found on Doppler ultrasonography of patients hospitalized for the diabetic foot in the Ivory Coast. Methods: We conducted a retrospective descriptive study including 235 patients hospitalized for the diabetic foot in the Endocrinology department of the Yopougon University Hospital from February 2002 to December 2015. All records of patients who performed arterial Doppler ultrasound of the lower limbs were selected and the various abnormalities were described. Results: The sex ratio (M/F) was 1.1 (124 men to 111 women). The predominant age group was 61.2 years. Type 2 diabetes was found in 97.4% of cases. The average evolution of diabetes was 8.9 years with extremes of 1 and 32 years. Wet gangrene was the most common type of lesion found in 75.8% of cases. On ultrasonography, 98.7% of the patients had an arterial abnormality of the lower limbs. It was bilateral in 62.2% of cases, dominated by atheromatous overloads and mediacalcosis in 46.4% and 43.8% of cases, respectively. Arterial stenosis was lesions hemodynamically found in 76.3% of cases and arterial occlusions in 32.7% of cases. The amputation rate was 72.7%. Conclusion: This study shows the high frequency of arterial abnormalities in patients with the diabetic foot with a predominantly distal involvement. Arterial Doppler ultrasound of the lower limbs remains an essential tool in the care of diabetic foot. This easily accessible, non-invasive examination has a key role in therapeutic decision-making.

Sugarcane Yield Variations in Northern and Central Ivory Coast as Influenced by Soil Water Balance over Two Critical Growth Stages

The influence of water deficit as main cane yield limiting factor in Ivory Coast was investigated on SUCAF Ferke 2 and Sucrivoire Zuenoula sugarcane commercial plantations. A soil water balance model was used to assess crop water uptake over two critical growth stages, namely stem elongation and yield formation, to be correlated with cane yields. Under simulated rainfed conditions, average yields performed on yearly basis （from 1991 to 1997） in both sites were highly dependent （linearly） on average crop water satisfaction ratio （ETa/ETm） over these critical growth stages. Under real field conditions in Ferke 2 （irrigation water being considered in addition to rainfall）, cane yields of early as well as late maturing sugarcane varieties obtained on yearly basis were dependent on average crop water satisfaction ratio over both growth stages. In Zudnoula, cane yield fluctuations were generally not predicted by crop water satisfaction ratio, regardless the cropping season considered. However, average cane yields obtained from year to year over the study period in both sugarcane schemes were highly dependent on the average crop water uptake ratio. This shows the important contribution of water in predicting yearly variations of average cane yields produced on Ivorian sugarcane commercial plantations.

Chinese Products in Ivory Coast:A New Material Culture and New Figures of Success

In this paper,we will focus on consumers of Chinese products,but also other key players in this revolution of Chinese products in Ivory Coast:Ivorian traders,paying particular attention to the micro-social consequences of the arrival of Chinese products on the daily lives of Ivorian people.To date,work on relations between China and Africa is still struggling to grasp the micro-social consequences of Sino-African trade in African economies.Most of this work perceives Sino-African trade in terms of threats or opportunities for the development of African economies.While attention is generally focused on Chinese imports from Africa,given their geostrategic value,we want to show,in the case of Ivory Coast,the profound transformations induced by imports of Chinese products into Ivorian society.Sino-Ivorian trade has grown rapidly in recent years.While in 2012,exports of Ivorian products by China were 55,515 billion francs CFA(Communautéfinancière d'Afrique);in 2016,they reached 42,3831 billion francs CFA,On the other hand,imports from China increased by a whopping 364,103 billion francs CFA in 2012,reaching 885,699 billion francs CFA in 2016.This increase in imports of Chinese products by Ivory Coast corresponds to the arrival of a wide variety of manufactured products in the Ivorian market.For many Ivorians,the presence of these products on the Ivorian market is an expression of good Sino-Ivorian cooperation.In order to appreciate the various dimensions of Chinese products in Ivorian territory,our communication will be part of an interdisciplinary approach and will be based on empirical observations and interviews conducted in Ivory Coast during 2014-2016.

PRODUCTION AND TRANSFORMATION OF IVORY BONE IN OSTEOARTHRITIC FEMORAL HEAD

Twelve femoral heads were collected during total hip replacement forosteoarthritis of hip joint. The areas on the femoral head denuded of articular cartilageand the ivory bone were studied with scanning electron microscope. The following findingswere observed: 1. Over the area denuded of articular cartilage, the subchnodral bone platerevealed flake-like trabeculae whick were unequal in size and haphazard in array. Therewas a transformation of the flake-like trabeculae into lamellar bone tissues. 2. Over theivory bone, the lamellar bone tissues turned into Haversian systems and interstitiallamellae, thereby revealing characteristics of compact bone and became extremely hard. 3.Over the surface of the ivory bone could be seen fibrocartilaginous islands, representingreparative response from the marrow tissues.

Predictors of Direct-Acting Antivirals Failure in Patients with Chronic Hepatitis C Virus in Ivory Coast: About 5 Cases

Context and Aim: Direct-acting antivirals are the therapeutic revolution in the management of viral hepatitis C, but often with a few cases of failure. The aim of this study was to identify factors that may be implicated in the failure of direct-acting antiviral therapy in patients with hepatitis C virus in Ivory Coast. Methodology: This was a cross-sectional and descriptive study with a retrospective compendium of data from the year 2016 to the year 2018. This study included all patients with chronic viral hepatitis C, patients naive to antiviral treatment, or pre-treated patients in whom a failure to treatment with direct-acting antiviral has been diagnosed. Results: During the study period, 5 patients out of 14 cases of therapeutic failure were included, i.e. 35.71%. Most of the patients were over 50 years (4 out of 5) and predominantly female (3 out of 5). High blood pressure was the most common comorbidity (3 out of 5 patients). Genotype 1 was found in 4 patients versus 1 case of genotype 2. None of the patients had hepatitis B or HIV coinfection. A viral load > 6log was found in 4 patients at baseline. All our patients had hepatic cytolysis. Two of them were cirrhotic. All 4 cases of genotype 1 benefited from the combination sofosbuvir + ledipasvir for 12 weeks and the case of genotype 2 from the combination sofosbuvir + ribavirin for 24 weeks. The resistance mutations were observed mainly on the sequencing of NS5A at the Y93H, L31M, 28L, 30T, 31V, 58S and 93H genes and a case of mutation on the N3 gene sequencing. Conclusion: Age > 50 years, comorbidities (high blood pressure), polymedication, female gender, genotype 1b, viremia > 6log, and cytolysis were the profile of patients with treatment of HCV by direct-acting antiviral failure.

Associated Risk Factors of Non-Communicable Disease in Three Sites across Ivory Coast: An Urban (Cocody), Peri-Urban (Abobo) and Rural (Yocoboué) Area

Introduction: The prevalence of Non-communicable diseases (NCDs) has increased so it’s becoming a global public health problem. This problem is also threatening in Sub-Sahara Africa (SSA) country including Ivory Coast. Ivory Coast is a country of 22.6 million people experiencing rapid economic development and social change. All development is typically associated with an increase in non-communicable disease (NCD) risk factors. Our study aimed to determine the prevalence and associated factors of the major risk factors of NCDs among the population of Cocody, Abobo and Yocoboué in the Ivory Coast. Methods: A descriptive and analytical cross-sectional study was conducted and involved 1146 adults of 19 to 60 years from general population in Cocody (urban), Abob (peri-urban) and Yocoboué (rural). The WHO STEPS risk factor survey has been changed a bit and was administered. it contains anthropometric and biochemical measures. Results: The prevalence of NCD risk factors was markedly different across the three sites particularly between urban (Cocody) and rural (Yocoboué) areas. The overall prevalence estimates of the risk factors were 15.2% for current smoking, 57.71% for harmful use of alcohol, 58.84% for low physical activity, 24.71% for sedentariness (sitting at least 7 h), 69.45% for skipping breakfast, 61% for having late dinner and 36% for snacking. Concerning biological risk factor we noticed 40.95% for Overweight/obesity, 52.96% for abdominal obesity, 14.61% for raised blood pressure, 23.37% for raised blood sugar and 18.51 low HDL-C. Being female has an important associated with an increased risk for having abdominal obesity (OR: 25.7) and being overweight or obese (OR: 11.3), suffering from hypertension increased with age, 30 - 39 years (OR 8.45), 40 - 49 years (OR 13.4) and 50 years and above (OR 24.6). Conclusion: Adult residents in the two (Urban and peri-urban) of three different areas are developing high-risk NCDs, particularly Cocody’s population. At the end, we observed among participants that the female gender, living in urban areas and clustering are the most concerned by non-communicable disease risk factors. To reach the goal, preventive and therapeutic interventions are needed among the targeted population.

Epidemiology and Histology Aspects of Breast Cancers of Women in Ivory Coast

Breast cancer is a major public health problem both in developed countries, where it represents the first female cancer, and in developing countries, where its incidence is increasing. Purpose: The authors report the results of a study whose objective was to describe the epidemiological and pathological features of women’s breast cancers in Ivory Coast. Material and Methods: This is a retrospective descriptive study on breast cancer histologically confirmed and made from the records of pathology laboratories of the University Hospital in Abidjan. The study period was 24 years (1984-2007). The parameters studied were: frequency, age, risk factors, the macroscopic and histological aspects. Results: Women’s breast cancer was the second cancer among women (13.69%) after cervical cancer and represented 6.51% of cancers. The average age was 45.21 years ranging from 10 years to 85 years. Subjects from 35 to 44 years were the most affected (30.7%) and 8% of patients were under 30 years (n=61). Multiparity (53.55%) and lower socioeconomic level (79.63%) were associated. At the macroscopic level nodular aspects represented 47.62% of cases (n=301). Carcinomas were 92% (n=710) of histological types with 94.36% (n=692) of invasive carcinomas. Sarcomas (5.7%), lymphoma (2.1%) and Paget’s disease (0.3%) were also observed. With regard to prognostic, the grading of Scarff-Bloom and Richardson showed 26.75% (n=156) grade I, 60.64% (n=354) grade II and 12.52% (n=73%) grade III. Conclusion: In consideration of prognosis of advanced forms, an effort should be made for diagnosis and early treatment of women’s breast cancer in Ivory Coast.

Sensitivity of Statistical Models for Extremes Rainfall Adjustment Regarding Data Size: Case of Ivory Coast

The objective of this study is to analyze the sensitivity of the statistical models regarding the size of samples. The study carried out in Ivory Coast is based on annual maximum daily rainfall data collected from 26 stations. The methodological approach is based on the statistical modeling of maximum daily rainfall. Adjustments were made on several sample sizes and several return periods (2, 5, 10, 20, 50 and 100 years). The main results have shown that the 30 years series (1931-1960;1961-1990;1991-2020) are better adjusted by the Gumbel (26.92% - 53.85%) and Inverse Gamma (26.92% - 46.15%). Concerning the 60-years series (1931-1990;1961-2020), they are better adjusted by the Inverse Gamma (30.77%), Gamma (15.38% - 46.15%) and Gumbel (15.38% - 42.31%). The full chronicle 1931-2020 (90 years) presents a notable supremacy of 50% of Gumbel model over the Gamma (34.62%) and Gamma Inverse (15.38%) model. It is noted that the Gumbel is the most dominant model overall and more particularly in wet periods. The data for periods with normal and dry trends were better fitted by Gamma and Inverse Gamma.

Late Season Sugarcane as Affected by Deficit Irrigation at the Yield Formation Stage in Northern Ivory Coast

A field trial was carried out in Ferk6 2 Sugar mill located in northern Ivory Coast, in order to study sugarcane growth and yield response to deficit irrigation imposed over the yield formation stage. The crop used was a first ratoon Co 957, a non flowering late season sugarcane variety. The experiment was completely randomized following a one-factor design with 4 water deficit treatments in 3 replicates. It came out that the optimum water deficit treatment reached 20%, i.e., 80% of crop water requirements were satisfied through irrigation. That treatment gave 7.9 kg cane/m3 or 0.98 kg sugar/m3 as irrigation water use efficiency. Relatively low crop growth rates （0.2-0.4 cm/day） as well as low cane yields （24.5-78.4 t/ha） were obtained as a result of an intensive and persistent dry season occurred over the yield formation stage. In line of prevailing climatic conditions, cane juice quality measured was particularly high on Co 957 which used to be a moderately performing variety in Ferk6 2 sugar mill.
