Few studies have been devoted to postpartum family planning in Mali. Our work will contribute to reducing unmet need for family planning. Objective: To study the use of contraceptive methods in the postpartum period in the obstetrics and gynecology unit of Timbuktu hospital. Materials and Methods: This was a descriptive and analytical cross-sectional study with prospective collection of data from January 1, 2022 to December 31, 2023. All women who gave birth having chosen and benefited from a contraceptive method were included. The statistical test used was the Fisher test with a significance threshold fixed at 5%. Results: The frequency of contraception in the postpartum period was 17.03%. The average age of clients was 26.14% with extremes of 14 and 45 years. They were paupiparous at 56.4% with an inter-birth interval of less than 12 months at 12.3%. More than half of the counseling (58.5%) was done during postnatal visits. The methods chosen were implants at 48.1%, injectable progestins at 21.3%, intrauterine device at 14.7%, miro-progestin pills at 13.5%, tubal ligation at 1 .4% and condoms at 1%. The regular follow-up rate was 51.1% of cases and 25.6% had no follow-up. Conclusion: The overall rate of postpartum family planning of 17.08% remains low. Improving FP staff skills will reduce unmet needs and contribute to increasing contraceptive prevalence in Timbuktu.展开更多

The questionnaires included MBI and Carlson work-family conflict questionnaires, and the data were analyzed using SPSS 17.Results: A total of 71.6% of nurses worked over 8 h per day during the last two months before the reevaluation. The total score of burnout of nurses was 66.84 ± 12.60, and the proportion of heavy work burnout was 44.2%. The personal accomplishment takes the heaviest portion(80.0%). The total score of work-family conflict is 55.19 ± 9.27. The scores of work-to-family conflict are all higher than that of family-to-work conflict. The time dimension had the highest score.Conclusions: During the preparation period, nurses suffered from a heavy workload and intense job burnout, and many aspects of work-family conflict existed.展开更多

How would nurses describe an optimal care transition? Nurses have a pivotal role during care transitions of older patients. More knowledge about their experiences is necessary to develop favorable improvements for this important period in the older patient’s treatment and care. The study has a qualitative explorative design with follow-up focus group interviews. Nurses (N = 30) working in hospital (n = 16) and municipal (n = 14) health care were organized in five mixed focus groups during the period October-January 2014/2015. The focus groups met twice, answering the research questions following a previously circulated semi-structured interview guide. The interview analysis was inspired by content analysis. The analysis resulted in the themes “Administrative demands challenge terms for collaboration” and “Essentials for nursing determine optimal care transitions for older patients”. Administrative demands may prevent nurses’ professional dialogue and collaboration across health care levels. Older patients’ best interests should be ensured through a collaborative relationship between hospital and municipal nurses, to form continuous care across health care levels. Clinical practice should be aware of essentials for nursing, which could influence and facilitate a more individualized and continuous transition for older patients.展开更多

Patients and Methods: The 12-month prospective study included 989 patients who were diagnosed with heart failure at the Institute of Cardiology of Abidjan and the Heart Department of the National Police Hospital in Cote d’Ivoire. Results: The mean age of the patients was 55 ± 12 years. Patients ≤ 50 years, aged 50 and 70 years, and ≥ 70 years were 42%, 60%, and 18%, respectively. The major cardiovascular risk factors were high blood pression (60%), smoking (19%), type 2 diabetes (11%), and hypercholesterolemia (8%). The status of 11% of HIV positive patients were ignored upon admission to the Heart Hospitals. Severe kidney failure (25%) was found in all hypertensive patients. Atrial fibrillation patients and sinus rhythm subjects were 20% and 80%, respectively. The average duration of QRS was 102 ± 24 ms. 20% of patients had a complete left bundle branch block. The mean of the left ventricular ejection fraction (LVEF) was 35.8% ± 13%. The LVEF was? ≤ 45% in 57% of cases and ≤ 30% in 30% of cases. The identified causes of heart failure were ischemic heart disease (60%), hypertensive heart disease (20%), and rheumatic valvulopathy (12%). Among the patients with ischemic heart disease, 80% were infarction. The coronarography and the myocardial revascularization were performed in 50% of cases. The primitive cardiomyopathy was diagnosed in 15% of cases. The average follow-up was 12.6 ± 8 months. 18% of patients died, 14% of whom deceased within 1 year after the initial diagnosis and 5% of death occurred in 19 months following the first symptoms of heart failure. The end stage of heart failure (13%) was the most frequent cause of death followed by the sudden death (5%) and the terminal kidney failure (2%). The patients were rehospitalized for heart failure (28 cases) and for ischemic stroke during the follow-up. The functional New York Heart Association score of patients was II in 39%, III in 43%, and IV in 18% at 1 month after admission.Conclusion: The heart failure is a major public health issue in Cote d’Ivoire as in many other African countries. The prevalence of ischemic heart disease as the leading cause of heart failure is certainly the reflection of the epidemiologic transition and the advent of the coronarography in the technical platform of the Abidjan Institute of Cardiology. The rapid evolution of the epidemiologic pattern of the heart failure in association with the increasing frequency of cardiovascular risk factors should contribute to implement study and prevention strategies against cardiovascular diseases in Cote d’Ivoire and in Africa.展开更多
