Introduction: Mechanical complications after osteosynthesis are spontaneous and harmful modifications of the joint compromising the consolidation process. The aim of this study is to report on the frequency of these complications and their management in the Orthopaedic-Traumatology Department of CHU Ignace Deen. Patients and Methods: we conducted a retrospective descriptive and analytical cross-sectional study from January 2017 to December 2022. It focused on the records of patients hospitalized and treated in the department for a mechanical complication after osteosynthesis. Results: The frequency of mechanical complications was 1.2%, with an average age of 44.2 years and a sex ratio of 3.2 in favor of men. Non-compliance with postoperative instructions, non-compliance with surgical technique, postoperative infection and early loading were the main contributing factors. Disassembly of the screw-plate was the most common cause in 6 cases (35.5%), with a mean delay of 4.1 months. Revision osteosynthesis was carried out using screw plates in 8 cases (47.1%). Conclusion: Mechanical complications of osteosynthesis are less frequent traumatic conditions in our department. Several factors contribute to their occurrence.

Internet of Things (IoT) networks present unique cybersecurity challenges due to their distributed and heterogeneous nature. Our study explores the effectiveness of two types of deep learning models, long-term memory neural networks (LSTMs) and deep neural networks (DNNs), for detecting attacks in IoT networks. We evaluated the performance of six hybrid models combining LSTM or DNN feature extractors with classifiers such as Random Forest, k-Nearest Neighbors and XGBoost. The LSTM-RF and LSTM-XGBoost models showed lower accuracy variability in the face of different types of attack, indicating greater robustness. The LSTM-RF and LSTM-XGBoost models show variability in results, with accuracies between 58% and 99% for attack types, while LSTM-KNN has higher but more variable accuracies, between 72% and 99%. The DNN-RF and DNN-XGBoost models show lower variability in their results, with accuracies between 59% and 99%, while DNN-KNN has higher but more variable accuracies, between 71% and 99%. LSTM-based models are proving to be more effective for detecting attacks in IoT networks, particularly for sophisticated attacks. However, the final choice of model depends on the constraints of the application, taking into account a trade-off between accuracy and complexity.

Hepatitis C infection in people living with Human Immunodeficiency Virus (HIV) poses management challenges. Of the world’s population, 3% are estimated to have chronic Hepatitis C Virus (HCV) infection, which is responsible for about 70% of cases of chronic hepatitis (accelerated chronicity in the presence of HIV and for such major complications as cirrhosis and hepatocellular carcinoma. The fibrosis 4 (FIB-4) and Aspartate aminotransferase/platelet ratio index (APRI) scores are simple, inexpensive tests accessible to most people, and their performance has not yet been studied in C?te d’Ivoire. Objective: To prospectively evaluate the diagnostic performance of APRI and FIB-4 scores in liver damage in those co-infected with HIV/HCV in C?te d’Ivoire. Methods: This study was conducted over three months. The patients came from national blood transfusion center of the cities of Man and Daloa. The criteria for selecting respondents were at least 18 years of age and a positive test for HIV and HCV. APRI and FIB-4 scores were calculated for each patient from biological data obtained by COBAS C311 (Roche Hitachi, Japan). Statistical analyses were performed using GraphPad and MED-CALC software. Results: Our study involved 30 patients (men) of middle age (25 - 52 years), with extremes ranging from 0.67 to 8 for APRI and 0.201 to 22 for FIB-4. A predictive APRI and FIB4 score of significant hepatic fibrosis was observed in 23% of patients;however, 46% and 54% of patients for the APRI and FIB-4 score, respectively, would not have significant fibrosis. An APRI and FIB4 score not included in the classification limits of the type of fibrosis hepatitis was observed in 31% and 23% of patients, respectively. Conclusion: The performance of the APRI and FIB-4 biological scores analyzed according to the interpretation of their cut-off values would enable classifying about 70% and 77%, respectively, of the patient population in the stages of hepatitis C fibrosis.

A study was conducted in Côte d’Ivoire to assess the after-effect of phosphate amendments on rice yields and soil properties. Eight types of amendments, composed of Moroccan phosphate rock (PRM) and triple superphosphate were tested in three agroecological zones over three consecutive years of cultivation. This study revealed that the application of Moroccan phosphate rock (PRM) and/or triple superphosphate (TSP) did not significantly affect soil cation exchange capacity (CEC) and organic carbon (Corg) content. However, there was a negative residual effect of PRM-rich treatments on soil pH and K and N content, but the impact varies depending on the characteristics of the soils studied. Furthermore, nutrient losses, notably nitrogen from −17.5 to −267.7 kg/ha and potassium (−0.1 to 0.7 kg/ha), were observed in all treatments. Only phosphorus showed a positive balance of +49.56 to +52 kg/ha in PRM-rich treatments. Treatment T3, composed of 80% RPM and 20% TSP, was the most effective in all zones, with a relative increase in grain yields of over 100% compared to the control. These results suggest that the input of natural phosphate rock can significantly improve rice yields and soil properties in the studied agroecological zones in Côte d’Ivoire.

The soil samples were collected taking into account the land use in Songon area. The hydraulic conductivity (K) of soils was characterized in-situ when specific yield (Sy), pHw and concentrations of Cooper, Iron, Zinc, Cadmium, Chromium and Lead were measured in the laboratory. Pollution load indices (PLI) were calculated to evaluate the soil contamination levels. The soils were neutral and alkaline (6.7≤ pH ≤ 9.20), permeable (1.9 í 10-5?m·s-1?≤ K ≤ 8.2 í 10-4?m·s-1), with a high specific yield (13.33% ≤ Sy ≤ 33.33%) which can favor the pollutants transfer. The heavy metals (Fe, Cu, Zn, Cd, Cr and Pb) have very high concentrations in soils. The integrated pollution indices (PLI) indicate that almost 70% of Songon soils are moderately contaminated by the investigated heavy metals, with windows presenting high indices of pollution related to the intensive use of fertilizers and pesticides. The establishment of new boreholes in the Songon area should consider these heavy metals, so as to avoid the risk of groundwater pollution due to the physical properties of soils.

Introduction: Sickle cell disease has physical and emotional repercussions on the child and his family. The aim of this study was to describe the psychosocial experiences of mothers of children with sickle cell disease in order to improve the overall care of the child. Methods: This was a descriptive cross-sectional study carried out in the pediatrics department of Bouaké University Teaching Hospital from June to September 2023. It focused on mothers of major sickle-cell-affected children followed up in the pediatrics department of the Bouaké University Teaching Hospital. The variables studied were sociodemographic, psychological, social and economic. Results: Of the 40 mothers surveyed, 15% were not in school and 32.5% were unemployed. For them, sickle cell disease was of natural (genetic) origin in 90% and supernatural in 10%. They stated that the child had an average age of 36 months (extremes 7 and 108 months) when the disease was discovered. And 52% of them were satisfied with the way the disease was clearly and completely announced. Following the announcement, the questioned mothers said they had felt shock (35%), sadness (31.7%), guilt (23.3%) and discouragement (10%). Anxiety and depression were experienced by 77.5% and 22.5% respectively. In 60% of cases, they stated that the disease was incurable, and the outcome was fatal in 2.5% of cases. The child’s illness was a source of problems in the home in 25% of cases, represented by arguments in 92% and divorce in 8%. In 97.5% of cases, the mother told her family and friends about the child’s illness. In 90% of cases, the mother and child benefited from psychological support from family and friends. Conclusion: Sickle cell disease is a serious illness with a psychological and social impact on mothers. We recommend psychological support for mothers from the moment of diagnosis and throughout follow-up.

Introduction:In C?te d’Ivoire, despite awareness raising among mothers by health authorities and health care providers, the exclusive breastfeeding rate is still low, 23%. This rate seems even lower in rural areas. The objective of the study was to evaluate the knowledge, attitudes and practices of mothers regarding exclusive breastfeeding for the reduction of malnutrition in rural areas. Methods: This was a descriptive and analytical cross-sectional study conducted in Brobo from July to September 2020. It included consenting mothers of infants aged 0 to 24 months. Mothers’ knowledge, attitudes and practice were assessed by an anonymous structured questionnaire with a performance threshold set at 75%. Factors associated with exclusive breastfeeding were investigated by the Chi-square test at the 5% level of significance. Results: The average age of the 183 mothers was 25 years (extremes 13 and 49 years). They were primigravida (33%) and had a low socioeconomic level (84%). The mothers knew the definition of exclusive breastfeeding (33%). They knew that breastfeeding promoted ideal infant growth (64%) and protected against diarrhea and infection (18%). They also knew that breastfeeding reduced the mother’s risk of cancer (16%) and strengthened the mother-infant bond (7%). The mothers interviewed stated that they had put the baby to the breast within the first hour after delivery in 2% and 63% of them gave the baby colostrum. Mothers were confident about breastfeeding (91%) and exclusive breastfeeding until 6 months of age represented 9%. The factor associated with lack of knowledge of exclusive b

Identify the epidemiological characteristics, etiologies and evolutionary aspects of dyspnea in infants. This was a retrospective study of infants hospitalized for dyspnea from January 1 to December 31, 2020. The parameters studied were sex, age, origin, vaccination status, existence of underlying pathology. Underlying, the diagnosis and the evolutionary modalities. Data analysis and processing were possible using Word, Excel and EPI info version 7 software. We retained 152 infants. The sex ratio was 1.34 and the median age was 4 months. Vaccines according to expanded immunization program (EPI) were up to date in 76.32%. The main antecedents with risk identified were malnutrition, hypotrophy at birth, interventricular communication. The pathologies observed were low acute respiratory diseases in 90.79%, ENT diseases in 04.60% and cardiac diseases in 03.95%. The median length of hospitalization was 4 days. Infants who died accounted for 15.13%. The median age of infants who died was 4 months. The median time to onset of death was 1.63 days. The risk factors for death were age < 6 months (p = 0.003;CI [1.27;9.33]), outdated vaccines (p = 0.012;CI [1.18;5.17]), history with risk (p = 0.031;CI [1.02;4.54]). Dyspnea in infants remains a concern in our service. Reducing mortality involves developing procedures for the management of lower respiratory ailments, continuous staff training and strengthening the technical platform.
