Small coastal pelagic fish are one of the fish families most affected by sea fishing. This man-made phenomenon leads to an imbalance in the marine and coastal ecosystem and is one of the main causes of migration north and offshore of the ranges. We used the ordinary differential equations to model the interactions existing between small pelagic resources and fishermen. Modelling follows the same of the Lotka-Volterra equations with a difference in the number of variables. This study confirmed the instability of the marine ecosystem. The objective is first of all to model a system of three interacting individuals composed of two distinct types of predators and two types of prey, and then optimise this interaction with the aim of conserving biodiversity in the ecosystem under study. Determining the Jacobian matrix made it possible to calculate the reproduction rate basic (r0). The study of the strong connectedness has made it possible to reduce the number of variables without losing the objective of the study. A computer program implemented on the language computer python facilitated the visualisation of the results.

Malnutrition is a global health problem. It is very common in developing countries where it contributes to an increase in morbidity and mortality, especially among children under five years of age. The main objective of this study was to describe the management of severe acute malnutrition (SAM) in children six months to five years of age hospitalized at Diamniadio Children’s Hospital (DCH). This was an epidemiological, retrospective, descriptive and cross-sectional study of children aged six to 59 months hospitalized at DCH for SAM. The study took place over a 12-month period (from January 1, 2018 to December 31, 2018). During the study period, 67 children were admitted for SAM, representing a hospital prevalence of 8.4%. The majority (88%) children were less than 24 months old. Reasons for consultations were dominated by diarrhea (57.5%) vomiting (38.8%). Complications related to SAM were mainly: anaemia (74.6%), infections (85%) and severe acute dehydration (40.3%). Factors associated with SAM were young age (infants under 24 months of age), poverty, the first four children of a sibling, poor behaviour of food diversification. The average length of hospitalization was 12 days. The nutritional recovery rate was 73.1% and lethality was 3%. Conclusion: The prevention of malnutrition must involve the fight against poverty, an optimal and well-diversified diet, monitoring the nutritional status of children up to five years of agerdana;">.

This study describes the floristic composition and structure of a woody stand in the Senegalese Sahel, paying particular attention to the edaphic factors of its floristic composition. A stratified inventory considering the different relief units was adopted. Woody vegetation was surveyed using a dendrometric approach. The results obtained show that the flora is dominated by a few species adapted to drought, such as Balanites aegyptiaca (L.) Del., Calotropis procera Ait. and Boscia senegalensis (Pers.). The distribution of this flora and the structure of the ligneous plants are linked to the topography. In the lowlands, the flora is more diversified and the ligneous plants reach their optimum level of development compared with the higher relief areas. In the lowlands, there are a few woody species which, in the past, were indicative of better climatic conditions. These are Anogeissus leiocarpus (DC.), Commiphora africana (A. rich.), Feretia apodanthera Del., Loeseneriella africana (A. Smith), Mitragyna inermis (Willd.) and Sclerocarya birrea (A. rich). It is important that their reintroduction into reforestation projects takes account of their edaphic preference.

Purpose: High urinary retention (HUr) can negatively impact renal function. Our study aimed to present the epidemiological, diagnostic, and therapeutic aspects of HUr in a Senegalese academic hospital. Patients and Methods: We conducted a retrospective study of 70 patients with HUr associated with renal failure from January 2017 to December 2020. Parameters examined included: age, sex, coexisting conditions affecting renal function, clinical symptoms, diagnostic tests, causes of HUr, urinary diversion, and patient outcomes. results: The average age was 66, with a majority of male patients (87%). Twenty-three patients had pre-existing medical conditions. Oligo-anuria was the most common reason for detecting HUr (70%). Half of the patients had an ECOG score ≥ 2. The mean creatinine level was 50.7 mg/l. Nineteen patients exhibited hydroelectrolytic disorders. Bacterial colonization was observed in 25 patients. Ultrasound and computed tomography were the most frequently performed imaging tests (100% and 62.8%, respectively). Sixty-seven patients had ureterohydronephrosis (UHN), with bilateral UHN in 88.6% of cases. Pelvic cancers (47.1%) were the primary cause of HUr, primarily bladder cancers (27.1%). Nephrostomy was the most common urinary drainage method (50%), particularly for obstructions due to pelvic cancer (88.6%). The majority of patients (52.8%) regained normal renal function after drainage. Nineteen deaths occurred among elderly patients with compromised general health. Conclusion: Urinary drainage significantly improved renal function for most patients. Pelvic cancer emerged as the leading cause of HUr. Nephrostomy was the predominant drainage method.

HIV/AIDS is a serious health problem among prisoners and constitutes a big challenge for prison administration services, public health services and governments. Aims: Determine the prevalence of HIV infection among prisoners and describe associated factors. Population and Methods: This was a descriptive and analytical cross-sectional study conducted from December 2015 to October 2016. A sample of 600 prisoners was randomly interviewed nationwide. They were selected directly from the sample frame from across the country and proportionally from all sites. Pre-established questionnaires providing information on the sociodemographic and biological characteristics of prisoners were used for the collection of data. Data entry and analysis were performed using EXCEL and SPSS 18 software. Results: The survey was based on a randomised sample of 600 prisoners, 593 of whom accepted blood extraction for the HIV testing. The series was mainly composed of males (89%). The median age was 33 years (18 - rdana;">69). The level of education among respondents was 60%. regarding marital status, the proportion of married prisoners was 51.8%. Almost three-quarters (71.5%) were at their first imprisonment and 51.8% were on preventive detention. The reasons for imprisonment varied and were dominated by drug use (35.3%), while only 4.6% confessed that they continued using drugs while in prison. 97.8% of prisoners have had a sexual experience. Their median age was 19 years at their first sexual interc

Introduction: Congenital heart disease (CHD) is a malformation of the heart present at birth and resulting from a developmental defect during embryonic life. The aim was to assess CHD in rural areas. Methodology: This is a retrospective study conducted over a period of 2 years in rural Senegal. results: During the study period, we collected 79 patients with CHD, representing a hospital prevalence of 2.6%. The mean age at diagnosis was 17.05 months and the sex ratio was 1.19. The mean birth weight was 2826 g. The main comorbidities were anaemia (54.43%) and respiratory infections 38 cases (48.10%). respiratory distress was the most common sign with 98.73%. radiological cardiomegaly was noted in 86.7%. The most frequent CHD were interventricular septal defect (IVD) 21.51% and atrial septal defect (ASD) 8.86%. No patient was able to receive surgical treatment. Seven children died (8.86%) and 21 children were lost to follow-up (26.58%). On Doppler echocardiography, 16.45% of the patients had pulmonary arterial hypertension (PAH). Conclusion: In light of this work, emphasis should be placed on the quality of antenatal consultations, the quality of management and the regular availability of echocardiography and a cardio-paediatrician in order to reduce morbidity and mortality.
