Introduction: Late pregnancies are considered a public health problem linked to maternal mortality due to their complications. These risks, which worsen with maternal age, should be better known and taken into account in monitoring these pregnancies. Objective: To evaluate the impact of age on the prevalence of obstetric and neonatal complications among parturients of 40 years old and over. Methodology: This was an 11-year retrospective analytical case control study from January 1, 2007 to December 31, 2017. The study population was female patients of 40 years old or older for cases and female patients younger than 40 years of control case. Results: In total, we collected 640 cases of parturients of 40 years old and over out of a total of 84,234 deliveries during the study period;i.e. a frequency of 0.76%. Spontaneous abortion increased in patients of 40 and over with 8.28%. Hypertension and diabetes were higher of women of 40 and over, 52.65%. Concerning the method of admission: 55% of parturients of 40 and over were referrals. Incidents occurring among women of 40 and over were more pronounced than in control cases. Complications during vaginal delivery, cervical tear, perineal tear, uterine dehiscence and uterine rupture are high in our cases, i.e. 11.88%;3.59%;2.19%;2.66. During our study, depending on the type of delivery, the cesarean rate was much higher among women of 40 and over than among control cases, i.e. 54.22% versus 12.24%. Hemorrhages in the 3rd trimester were the main indications for cesarean section. Hemorrhages in the 3rd trimester were more frequent with women of 40 and over, i.e. 10.47%;5.94% versus 1.74% and 0.42%. As for the different types of malformations in parturients, women under 40 years old fetal malformations were absent in 92.29%, on the other hand they were more frequent in patients with 40 years and over, i.e. a normal frequency of 36.72%. Conclusion: Pregnancy at a late age exposes the elderly patient and the newborn to several ri

Introduction: Maternal mortality constitutes a public health problem and its rate is an indicator of a country’s development. Among the causes of maternal and perinatal death, high blood pressure associated with pregnancy occupies a significant part. It represents 5% of direct maternal deaths. Objective: to study the maternal and perinatal prognosis of high blood pressure during pregnancy in the Tenenkou reference health center in Mali. Methodology: This was a descriptive, analytical and retrospective cross-sectional study over a period of twelve months from January 1, 2021 to December 31, 2021 and involving 144 cases of high blood pressure associated with pregnancy. Results: We obtained a frequency of 11.75%. The majority of patients 70.9% were aged between 20 - 35 years. The important risk factor found was young age. During our study, 46.5% of patients had performed at least one CPN and only 13.9% performed 04 CPN. Pre-eclampsia was the most common type of high blood pressure during pregnancy, i.e. 61.1%. Eclampsia and retroplacental hematoma were the most common maternal complications, respectively 27.8% and 11.1%. The most common fetal complications were premature births and fetal distress with 20.9% and 17.4% respectively. Conclusion: Hypertension associated with pregnancy still remains a major cause of maternal-fetal morbidity and mortality in our context where diagnosis is often late. The main clinical form was preeclampsia. Eclampsia and retroplacental hematoma were the most frequent maternal complications. Fetal complications were mainly prematurity and fetal distress.

Introduction: Uterine fibroid is a mixed mesenchymal tumor, developing from smooth muscle cells of the myometrium, separated by connective tissue. The majority of fibroids are asymptomatic and do not require any intervention or other exploratory measures. However, in some cases fibroids are symptomatic, their treatment should aim to improve symptoms and quality of life. Objectives: Describe the epidemiological-clinical aspects of uterine fibroids in the gynecology and obstetrics department of the reference health center of commune VI of the Bamako district. Methodology: This was a retrospective descriptive study carried out over a period of one year. It concerns all patients seen in consultation in the gynecology and obstetrics department of the reference health center of commune VI. Results: during the study period, the uterine fibroid frequency was 1.80%. During this same period, fibroids represented 5.59% of gyneco-obstetric pathologies operated on in the department. The 30 - 45 year old age group was the most represented with a frequency of 75.63%. The average age was 36.87 years ± 6.2 years with extremes of 25 and 63 years. Married women were the most represented 97.48%. The vast majority of our patients 95.8% were not postmenopausal. The multigravidas were the most represented, i.e. 37.50% with a large part of the pauciparous 41.29%. In our patients, 96.64% had a clinical symptom on their fibroid with the main reason for consultation being the sensation of a pelvic mass in 97.48%. We recorded three cases of infertility as associated factors. Ultrasound was performed in all patients. The location of the myxomatous nuclei was subserosal in the majority in 42.86% and with multiple nodules in 84.85% of cases. The main indication for myomectomy was the failure of medical treatment in 86.49% of cases. Surgical treatment was mainly a myomectomy 93.30%, a hysterectomy was indicated in 6.70%. No cases of death were recorded. Conclusion: Uterine fibroid is a gynecologic

On the Optimal Design of Cable Driven Parallel Robot with a Prescribed Workspace for Upper Limb Rehabilitation Tasks

Journal of Bionic Engineering 2019年第3期16卷 503-513页

This paper deals with an optimization approach to design a cable driven parallel robot intended for upper limb rehabilitation tasks. The cable driven parallel robots have characteristics that make them best candidate for rehabilitation exercise purposes such as large workspace, re-configurable architecture, portability and cost effectiveness. Here, both the cable tensions that are needed to move a wristband as well as the workspace need to be carefully optimized for fulfilling the prescribed operation tasks. A specific case of study is addressed in this work by referring to LA RM wire driven exercising device (LAWEX), which is applied to upper limbs exercises. To that end, a motion capture system is used to collect quantitative data on the prescribed workspace of a human upper limb. A specific optimization problem is settled up for considering combining two optimization goals, namely, the smallest robot size reaching a prescribed workspace and the minimum cable tension distributions. A sequence of optimization steps is defined using Genetic Algorithms (GAs) applied to LAWEX robot. The proposed objective function is based on a mathematical formulation of the power of a point with respect to bounding surfaces in combination with a performance index to show the distributions of the minimum cable tensions.

Analysis and optimal synthesis of single loop spatial mechanisms

Journal of Zhejiang University-Science A(Applied Physics & Engineering) 2011年第9期12卷 665-679页

作者： med Amine LARIBI Lotfi ROMDHANE Sad ZEGHLOUL Laboratoire de Génie Mécanique LAB-MA-05 Ecole Nationale d'Ingénieurs de Sousse Institut Pprime-UPR 3346 CNRS-Université de Poitiers-ENSMA Département Génie Mécanique et Systémes Complexes SP2MIBP30179 86962 Futuroscope France

In this work, a systematic approach is presented to obtain the input-output equations of a single loop 4-bar spatial mechanisms. The dialytic method along with Denavit-Hartenberg parameters can be used to obtain these equations efficiently. A genetic algorithm (GA) has been used to solve the problem of spatial mechanisms synthesis. Two types of mechanisms, e.g., RSCR and RSPC (R: revolute; S: spherical; C: cylindrical; P: prismatic), have illustrated the application of the GA to solve the problem of function generation and path generation. In some cases, the GA method becomes trapped in a local minimum. A combined GA-fuzzy logic (GA-FL) method is then used to improve the final result. The results show that GAs, combined with an adequate description of the mechanism, are well suited for spatial mechanism synthesis problems and have neither dificulties inherent to the choice of the initial feasible guess, nor a problem of convergence, as it is the case for deterministic methods.

An Experimental Analysis of Overcoming Obstacle in Human Walking

引用

Journal of Bionic Engineering 2014年第4期11卷 497-505页

作者： Tao Li Marco Ceccarelli Minzhou Luo med Amine Laribi Said Zeghloul Institute of Advanced Manufacturing Technology Hefei Institutes of Physical Science Chinese Academy of Sciences Changzhou 213164 P. R. China Laboratory of Robotics and Mechatronics University of Cassino and South Latium Cassino 03043 Italy Institute PPRIME- DGMSC CNRS-University of Poitiers- ENSMA 15 Rue de l'Hotel Dieu 86000 Poitiers France

In this paper, an experimental analysis of overcoming obstacle in human walking is carried out by means of a motion capture system. In the experiment, the lower body of an adult human is divided into seven segments, and three markers are pasted to each segment with the aim to obtain moving trajectory and to calculate joint variation during walking. Moreover, kinematic data in terms of displacement, velocity and acceleration are acquired as well. In addition, ground reaction forces are measured using force sensors. Based on the experimental results, features of overcoming obstacle in human walking are ana- lyzed. Experimental results show that the reason which leads to smooth walking can be identified as that the human has slight movement in the vertical direction during walking; the reason that human locomotion uses gravity effectively can be identified as that feet rotate around the toe joints during toe-off phase aiming at using gravitational potential energy to provide propulsion for swing phase. Furthermore, both normal walking gait and obstacle overcoming gait are characterized in a form that can provide necessary knowledge and useful databases for the implementation of motion planning and gait planning towards overcoming obstacle for humanoid robots.
