Introduction: Despite progress in universal health coverage, maternal mortality remains a concern for developing countries, including Mali. the problem is not due only to a lack of health services but to a combination of factors that need to be identified to give hope to women of childbearing age. Objective: Determine the factors associated with maternal mortality in the timbuktu region of Mali. Methodology: Retrospective, descriptive, cross-sectional and analytical study from January 1, 2018 to December 31, 2022 using a questionnaire and an interview guide to determine the factors associated with maternal mortality in the timbuktu region of Mali. Results: A total of 112 maternal deaths were recorded between 2018 and 2022. the average age of the women who died was 26 years (standard deviation 7.6 years). the 14 – 23-year-old age group is the most affected (43.8%). 66.1% of women came from rural areas. Illiteracy (77.7%), lack of ANC (54.5%), distance of households from health facilities (76%) and insecurity (52.7%) have been identified as factors contributing to maternal mortality. Conclusion: this study reported a high prevalence of maternal mortality rates that may be associated with women’s socioeconomic conditions. Actions must be developed to integrate CPN into an advanced strategy for women living in rural areas in Mali.

Introduction: Worldwide, 2.3 million children died in the first 20 days after birth in 2022, according to the WHO. In Mali, according to the sixth Demographic and Health Survey, the neonatal mortality rate was estimated at 33% live births in 2018. the timbuktu region had the highest neonatal mortality rate in the country with 44%. the objective of this work was to study the causes of neonatal morbidity and mortality and related factors in the paediatrics department of timbuktu hospital. Materials and method: this was a descriptive, cross-sectional study conducted from 1 January to 31 December 2023 in the neonatology unit of the paediatrics department of timbuktu hospital, including all newborns admitted to hospital. Results: Our study took place over 12 months, during which 618 admissions were made to the paediatric ward, including 244 newborns, i.e. 39.48%. the majority of newborns (86.5%) were admitted in the first week of life. the mean age was 3 days, with a sex ratio of 1.1 for males. Weight under 2500 g was 54.1% for an average weight of 2372 g. the main mode of admission was transfer from the hospital maternity unit (62%). the main reasons for admission were acute foetal distress (27.9%) and prematurity (26.2%). the average age of the mothers was 24, with extremes of 15 and 49. the mothers were housewives (87.3%), uneducated and primiparous (59% and 36.5% respectively);only 40.2% had made more than 3 antenatal care visits. Newborns born by vaginal delivery accounted for 80.7% and those born by caesarean section for 19.3%. the risk of infection was present in 52.5% of cases. the three leading causes of hospitalisation were birth asphyxia (40.2%), neonatal infection (32.4%) and prematurity (25%). the mortality rate was 21.7%. the main causes of death were prematurity (39.6%), birth asphyxia (32.1%) and neonatal infection (24.5%). Conclusion: Neonatal morbidity and mortality remain a concern in timbuktu. Despite the unfavourable security situation, morbidity and

Context: In Burkina Faso, there is only one retinoblastoma treatment center located in the capital. Nowadays, the treatment of retinoblastoma has benefited from the contribution of scientific progress. Objective: the aim was to take stock of the situation of retinoblastoma in the pediatric oncology department from January 1, 2010 to December 31, 2019. Materials and Methods: this was a descriptive cross-sectional study with retrospective data collection over a 10-year period, based on records of patients admitted to pediatric oncology department of CHU-YO. Data were analysed using CS Pro version 7.2 software. Categorical variables were compared using Pearsons Chi-square test at the 5% significance level. Overall survival was estimated using the Kaplan-Meier method. Operational definitions were used for lost to follow-up, consultation and diagnosis delays. Results: We collected a total of 204 cases in 10 years, i.e. an annual average of 20.4 cases/year. the mean age at diagnosis was 37.5 months for unilateral cases and 26.4 months for bilateral cases. Male predominance was noted, with a sex ratio of 1.31. the majority of patients came from disadvantaged backgrounds (72% farming fathers and 91% housewives). Clinically, leukocoria and exophthalmos were the main presenting features. the average time to consultation was long (8.73 months) and unilateral localization was predominantly unilateral at 77%. In terms of treatment, 102 patients were eligible for curative treatment and 80 for palliative treatment. the prognosis was poor, with 41% death and numerous cases of lost to follow-up (18%). Overall survival was estimated at 32%. the factor associated with the lethality of retiniblastoma was the extension of the tumor to other organs. Conclusion: Recognition of the early clinical signs of retinoblastoma can anticipate the occurrence of this cancer. Health professionals should be encouraged to perform the Buckner test every time they come into contact with children aged 0 t

Introduction: Postpartum family planning is the prevention of pregnancies during the 12 months following childbirth. 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.

the Dialafara area is part of the highly endowed Kédougou-Kéniéba Inlier (KKI), West-Malian gold belt, which corresponds to a Paleoproterozoic window through the West African Craton (WAC). this study presents, first of all, an integration of geophysical data interpretation with litho-structural field reconnaissance and then proposes a new litho-structural map of the Dialafara area. the Dialafara area shows a variety of lithology characterized by volcanic and volcano-sedimentary units, metasediments and plutonic intrusion. these lithologies were affected by a complex superposition of structures of unequal importance defining three deformation phases (DD1 to DD3) under ductile to brittle regimes. these features permit to portray a new litho-structural map, which shows that the Dialafara area presents a more complex lithological and structural context than the one presented in regional map of the KKI. this leads to the evidence that this area could be a potential site for exploration as it is situated between two world-class gold districts.

Introduction: Upper digestive hemorrhage is one of the main digestive emergencies and remains a major cause of morbidity and mortality in Mali. the aim of this study was to describe the therapeutic profile and outcome of patients suffering from upper digestive haemorrhage. Methodology: this was a prospective study carried out in the internal medicine department of the Sikasso Regional Hospital from August 2022 to July 2023. All adult patients presenting with upper digestive haemorrhage and having given their consent, were included. Data were analyzed using SPSS version 21 software. Results: Sixty-three patients were enrolled. the mean age was 49.7 ± 18.99 years, with a male-female sex ratio of 2.2. Ruptured esophageal varices (37.5%) and peptic ulcer (25%) were the main etiologies. Pharmacological treatment was dominated by proton pump inhibitors (85.7%). Hemostasis endoscopy accounted for 3.17%. the evolution was marked by hemorrhagic arrest (69.84%), recurrence of hemorrhage (11.11%) and death (19.04%), the main cause of which was hemorrhagic shock (58.3%). We found no statistically significant relationship between prognosis and etiologies (P = 0.11), and length of hospital stay (P = 0.18). Conclusion: Hemostasis endoscopy remains a challenge for Sikasso Hospital. A holistic strategy of communication and community awareness-raising, combined with adequate technical facilities, will help to improve patient care and outcomes.

从化石燃料中脱硫仍然存在许多环境问题、工业问题、甚至是经济问题。在很多情况下,硫化合物、脱硫成本高、催化性能不稳定和燃烧效率低都是非环境良性影响。因此,基于有效地脱硫方法的发展,人们坚持不懈的努力解决这些障碍以替代加氢脱硫,加氢脱硫技术效率低并且所需环境恶劣。催化氧化脱硫可以在温和的条件下进行,是一种非常具有前景的脱硫过程,但是催化剂的溶解性、溶剂的重复利用是获得超低硫柴油不可避免会面临的阻碍。利用离子液体代替复杂的有机溶剂不仅能够很容易的重复使用,而且还能提高催化效率。因此,我们采用离子液体和Keggin型含钒多金属氧酸盐进行催化氧化脱硫。结果清楚地表明,催化剂的催化氧化脱硫效率达到99.14%,并且循环使用5次整个催化体系的催化效果仍然很好。因此,催化氧化脱硫的简易性和高活性使得它能够代替加氢脱硫广泛地适用于工业脱硫。

Its management often relieves resuscitation that is often difficult to set up in our countries and sometimes based on invasive and mutilate surgery. Objectives: the purpose of this survey was to report frequency of this pathology, to describe its management and the factors that influence the prognosis of early postpartum hemorrhage in low setting health in Africa. Method: Authors conducted a prospective study that analyzed early postpartum hemorrhage in the motherhoods of Gabriel touré teaching hospital and community five health reference center of the district of Bamako. It took place from January, 2015 to December, 2016. the study concerned all the cases of early postpartum hemorrhage according to WHO definition. Statistical tests used were X2 or Fisher test, its 95% confidence interval (CI95%), p value was significant if Results: Early postpartum hemorrhage frequency has been 0.7% (62 cases for 8.885 deliveries). Sixty nine and one percent (69.1%) of patients have been blood fluid transfused. Obstetric treatment dominated by uterine revision (30.7%). Hysterorraphy (4.0%), hysterectomy (3.0%), suture of uterus injuries (15.7%), hypo gastric artery ligature (2.0%) and B-Lynch compression suture (2.0%) have been the main practiced surgical operations. No satisfy blood transfusion need was 26.9%. the main risk factors of early PPH were high parity (p = 0009;RR = 3.04;CI95% [2.80 - 5.11]), prolonged labor (p = 0004;RR = 4.00;CI95% [3.06 - 10.02]), oxytocin/prostaglandin use (p = 0003;RR = 1.47;CI95% [1.17 - 3.16]). Eleven of maternal occurred (11.8%). Conclusion: Early postpartum hemorrhage is still a severe event in developing countries especially. Its management sometime consisted to invasive cares. Maternal prognosis that is influenced by unsatisfied blood need and late management is marked by high lethality.
