The cropping system is based on traditional farming in rural areas. In this way, yields of some food crops like yam are very low considering their high need for nutrients. The nutrient-rich land is under high land pressure as it is occupied by cash crops such as oil palm and rubber at the expense of food crops and soil fertility is declining. The study was conducted in Grand-Lahou to assess the effect of organic matter provided by legumes in increasing yam yield. The randomized complete block design included four (4) treatments: Arachis hypogaea + yam association (T1), Acacia mangium + yam association (T2), Arachis + Acacia mangium + yam association (T3) and pure yam crop (T0). The parameters measured were: the soil nutrients content, the rate of mineralization of organic matter through the C/N ratio as well as the yield of yam through different techniques that allowed the objective of the study to be achieved. It was noted a slight improvement of nitrogen and organic carbon in all treatments with a higher value recorded in the T2 treatment. The C/N ratio decreased to 12 in all treatments compared to the control, which reflects a normal decomposition of the organic matter. Treatment T1 increased yam yield (8.4 t/ha) in contrast to treatments T2 (4.1 t/ha) and T3 (2.8 t/ha). Legume-based treatments T2 and T3 were associated with a significant decrease in yam yield, resulting in losses of −46.34% to −25.09%, while treatment T1 resulted in a gain of 28.57%. As a result, the treatments involving legumes contributed to normalizing the organic matter content of the soil. The simultaneous association of these two legumes led to a decrease in yam production, contrary to the treatment associating only groundnut.

Introduction: Infant and child morbidity and mortality linked to infections remain a major concern in both developed and developing countries. The general objective was to determine the characteristics of hospital morbidity and mortality linked to infectious pathologies in the pediatric department of the King Baudouin hospital center in Dakar. Methods: This was a retrospective, descriptive and analytical study focusing on children hospitalized from January 1, 2018 to December 31, 2021 in the pediatric department of the King Baudouin hospital center in Dakar. Results: During the study period, 1474 children were hospitalized for an infectious pathology in the pediatric department. The sex ratio was 1.48. Children aged between one and twelve months represented 34.12%. Morbidity due to respiratory and digestive infections was 42.33% and 33.45%, respectively. Pediatric hospital mortality was 0.75% with a predominance noted in infants between 1 and 12 months (55.86%). Respiratory, digestive infections, sepsis and neurological infections were the main causes of death. Factors associated with mortality were age (1 to 12 months) with p Conclusion: Reducing infant and child mortality linked to infectious diseases remains a crucial challenge to address for improving children’s health. Early detection of related signs, prevention of infections, and adequate care and monitoring of infants and children can contribute to this reduction.

Background and Objectives: The indication for treatment in HBsAg-positive patients with low viral load and normal transaminases requires an assessment of fibrosis. In resource-limited settings, free hepatic fibrosis evaluation tests can aid in therapeutic decision-making. Our study aims to demonstrate the utility of assessing hepatic fibrosis using non-invasive markers (APRI and FIB-4) in patients with chronic B viral hepatitis without cytolytic activity and low viral replication in our context. Patients and Methods: This is a retrospective cross-sectional study conducted between January 2018 and December 2021 at the University Hospital Center of Bouaké. Included were all patients aged ≥18 with normal transaminases (Results: Our study included 241 patients, with a mean age of 36.19 years (±10.52 years) and a male predominance of 52%. The mean FibroScan® value was 6.44 ± 2.3 kPa, and 68 patients (28.22%) had fibrosis >7 kPa. To exclude significant fibrosis (FS Conclusion: A significant proportion of HBV-infected patients with normal ALT and low viral load have active liver disease. Both FIB-4 and APRI biological scores are useful in identifying individuals without significant fibrosis with a good negative predictive value (>50%).

以废玻璃为原材料,采用水热合成法制备方沸石,探究其对废水中Pb^(2+)、Cd^(2+)和Cu^(2+)的吸附性能。通过批式实验系统考察了多种物理化学因素(pH、温度、接触时间等)对吸附量的影响。结果表明,初始pH对吸附量的影响较为显著,而温度变化对平衡吸附量的影响较小。确定了方沸石吸附Pb^(2+)、Cd^(2+)和Cu^(2+)的最佳工艺参数。利用Langmuir等温线模型对方沸石吸附水中的Pb^(2+)、Cd^(2+)和Cu^(2+)过程进行拟合,结果表明,该吸附过程是均质单分子层吸附,且吸附动力学特征更符合准二级动力学方程,证实了该吸附过程主要通过离子交换、化学吸附和表面络合作用实现。为废玻璃的资源化利用及废水中重金属的去除提供了一种低成本、高效率的方法。
