To show its interest in the African context, in the management of heart disease, a prospective study was carried out. Its objective was to evaluate the effects of physical rehabilitation on cardiac function. Methods: Patients were evaluated at the beginning and at the end of cardiovascular rehabilitation by cardiovascular, biological, and echocardiographic parameters including the size of the heart chambers, the kinetics of the walls, and the systolic function of the ventricles. Results: The study involved 12 patients, 67% of whom were men. After cardiac rehabilitation, the mean hemodynamic constants had not been significantly modified. However, a significant decrease in Total-Cholesterol, LDL-Cholesterol and triglyceride levels was noted. Mean fasting blood sugar decreased from 1.25 ± 0.48 g/L to 0.92 ± 0.18 g/L and glycated hemoglobin from 7.72% ± 0.01% to 6.45% ± 0.008%. The echocardiographic parameters studied showed an improvement in the dilation of the heart chambers in 8.33% of the patients, the normalization of the ejection fraction of the left ventricle in 16% patients, the improvement of the kinetic disorders in 16% of patients and recovery of right ventricular systolic function in all patients. Conclusion: Cardiac rehabilitation as a secondary preventive measure for cardiovascular disease has contributed significantly to improving the clinico-biological parameters of the disease.展开更多

Workers in this professional environment do not have access to individual and collective means of protection adapted to the activity, which exposes them to the dust emitted during their activity and therefore contributes to increasing the risk of developing respiratory disorders in this population. Objective: Our study aimed to evaluate the ventilatory function of metal welders in the city of Dakar. Method: This was a comparative study based on the analysis of the spirometric parameters of metal welders working in the city of Dakar (Senegal) with those of a control group of the same kind, selected from the general population. Measurements of forced expiratory volume in the first second (FEV1), forced vital capacity (FVC), peak expiratory flow (PEF) and maximum mid expiratory flow (MMEF) were measured. Results: A total of 75 men between the ages of 19 and 61 were recruited and divided into two groups (43 controls and 32 welders). The welding population had more frequent distal and central obstructions and pulmonary restriction compared to the control group. The metals most commonly used by welders were aluminum for welders who had an obstruction, while for those who had a restriction, iron was the most used metal. Signs of metal fever were frequently found in welders, especially those with ventilatory disorders. Conclusion: The prevalence of respiratory disorders observed is close to that observed in industrial environments, where exposure levels are the highest. The lack of personal protective equipment could also be a significant risk factor in the development of these disorders.展开更多

The combination of a sustained high ventilation and provocative training environments may impact the susceptibility of athletes to ventilatory disorders. Previous studies suggest that impaired ventilatory function in elite athletes can be detected in the absence of respiratory symptoms even after cessation of sports activity. The purpose of this study was to evaluate the ventilatory function of elite athletes compared to sedentary subjects. Material and Methods: This study included sedentary subjects and elite athletes, all male, aged 16 to 23 years. The athletes played regularly in the Senegalese league 1 championships (football and basketball) for at least two seasons with more than 10 hours of training per week during two years. For all participants, an interrogation was submitted and we conducted a clinic examination was performed following by a basic and post-bronchodilator spirometry. Results: The mean age of athletes (n = 66) and sedentary subjects (n = 61) was respectively 19.16 ± 2 years and 19.54 ± 2.12 years. The elite athletes presented significantly higher spirometry values (p Conclusion: This study found a high prevalence (72.73%) of ventilatory disorders (VD) in Senegalese elite athletes. Many previously undiagnosed elite athletes had significant ventilatory problems. To prevent the respiratory risk, athletes should be encouraged to avoid certain environmental factors and to adapt the period of their training.展开更多
