Journal of Health Science 2014年第3期2卷 152-156页

Facility records of 320 TB （tuberculosis） patients were examined over a one-year-period; January-December 2009 to ascertain the screening of children under 6 years of age who have had contacts with sputum smear positive TB patients as stipulated in the NTBLCP （National Tuberculosis and Leprosy Control Program） guidelines. In addition, semi-structured questionnaires were administered to 28 DOTS （directly-observed treatment strategy） clinicians to elicit information to help explain findings from the analysis of the routine data. Over 60% of children less than 6 years of age who had contacts with TB patients were not investigated in the health facilities included in the survey. The level of educational attainment of DOTS providers was associated with the screening of TB patients＇ contacts （P = 0.008）. Forgetfulness by clinicians to ask for or screen children of TB patients in the facilities is the singular most important factor undermining contact investigation. The proportion of under 6 years TB contacts screened or not screened for TB in the facilities was similar according to the age and gender of TB patients, and the type of health facilities where treatment was accessed by patients （P = 0.325）. The study underscored the need for the state program to evaluate the quality of service provision as well as counseling provided to TB patients at the facilities.

Advances in Biological Chemistry 2023年第3期13卷 100-109页

作者： Louise Odile Moke-Bedji Assieoussou Jean-Luc N’Guessan Lydie Boyvin Colombe Lohore Gnogbo Alexis Bahi Allico Joseph Djaman amos Ankotche Diabetes and Hypertension Clinic Treichville University Hospital Abidjan C&#244te d’Ivoire Faculty of Biosciences Felix Houphou&#235t-Boigny University (UFHB) Abidjan C&#244te d’Ivoire Department of Fundamental and Medical Biochemistry Institute Pasteur of C&#244te d’Ivoire (IPCI) Abidjan C&#244te d’Ivoire

Background: Type II diabetes mellitus is associated with multiple metabolic derangements which can cause secondary pathophysiological changes in multiple organ systems. This in turn can impose a heavy burden of morbidity and mortality from micro‑ and macro‑vascular complications. This study aimed to describe the metabolic and therapeutic profile of a subgroup of type 2 diabetic patients who have treatment failure with oral anti-hyperglycemic agents with persistent hyperglycemia despite insulin treatment. Methods: 60 type 2 diabetic patients in treatment failure with oral antidiabetics and under insulin treatment, aged 35 to 70 years, were recruited at the Diabetes Clinic of the University Teaching Hospital of Treichville in Abidjan, Côte d’Ivoire. Blood samples were collected in tubes containing Ethylenediaminetetraacetic Acid (EDTA) to determine glycated hemoglobin (HbA1c). Results: The average age of the population was 54 ± 9.38 years with a sex ratio (M/F) of 0.3, an average BMI of 30.25 ± 5 kg/m2, and an average HbA1c of 10.1% ± 1.6% for an average diabetes duration of 11.8 ± 5.8 years. The average insulin dose was 74.556 ± 16.21 UI/day, and the average duration of insulin treatment was 5.4 ± 3.1 years. The average HbA1c value was 10.1% ± 1.87% in men against 10.03% ± 1.53% in women with no significant difference (p = 0.1). The mean HbA1c values according to patient weight were 10.08% ± 2.05% for normal weight, 9.55% ± 2.26% for overweight, and 10.57% for obese, with no significant difference between the three groups of patients (p = 0.1). Conclusion: This study showed a persistence increase in glycated hemoglobin regardless of the treatment regimen, duration, and dose of insulin treatment in the subpopulation of type 2 diabetic patients.

Socioenvironmental Drivers of Farmers’ Perceptions of Climate Change Risk in Agroforestry Parklands of West Atacora in Benin (West Africa)

Open Journal of Ecology 2024年第1期14卷 54-65页

Throughout the world, climate change is threatening the human population. In West Africa, smallholder farmers in indigenous agricultural societies typically hold considerable knowledge. Therefore, this study was conducted in West Atacora of Benin Republic to assess the drivers of farmers’ perceptions of climate change risk. We used a random sampling technique to select 360 households’ heads who were interviewed regarding different climate change risks perception. Binomial logistic regression was used to assess the drivers of farmers’ perceptions of climate change risks. The results showed that the farmers in drier areas had a higher perception of the global risk of climate change than those in humid areas. The same trend was observed for the seven different individual’s climate change risk investigated. The study identified also membership of farm organizations as main sociodemographic characteristic that explains farmers’ perception of climate change risk perception. These findings are helpful tools to sensitize the local people on climate change risk and cope with the risk in agricultural lands.

为适应市场需求,Napier公司在上个世纪90年代末研制了NA297和NA357型涡轮增压器产品。这些产品在海运和发电应用领域确立了稳固的地位。开发工作的一个基本组成部分是一个受控的验证程序,Wrtsil柴油机公司对此给予了特别支持。该程序包括,在交付现场试验之前,先在Napier试验台上对涡轮增压器进行全面试验,然后在试验室内进行与发动机的配机试验。验证程序特别规定要在苛刻条件下(诸如:超负荷和负荷循环)测试涡轮增压器的性能和适应能力。进一步的现场验证还使公司能对更长期的效果(例如烧重油)作出评价。指定用于验证的样机仍处于监测之中,其验证结果被用于产品改进和强化新的开发工作。NA297和NA357型增压器的成功经验和通过验证程序的执行而产生的自信促进了Wrtsil公司和Napier公司之间在新的7系列产品方面的交流。新的NA397和NA307型增压器就是这种合作的结果。这些增压器的开发建立在早先产品的成功基础上,同时也吸收了在验证过程中得到的经验。NA397型涡轮增压器采用新的空气动力学叶轮和涡轮结构,并有许多其它新的或改进的结构特点。分析能力的提高有助于优化设计,最大限度地减小了叶轮的应力。采用了新的涡轮端密封系统,从而允许使用更高的油压,并且对因烧重油时润滑油污染造成的磨损加速问题更具适应能力。这种封密已被装置试验、试验台试验和现场运用所认可,从而确认其可信度。亦对增压器的涡轮出气壳进行了结构改进,采用新的转速传感器、模件式隔热装置并改变加工工艺以改进质量和控制成本。NA397型涡轮增压器在顺利通过第一阶段——试验室试验和装机试验后,于2003年夏季开始进行现场试验验证。在此期间,增压器以超负荷长时间运行并完成了500次快速全负荷循环。增压器还经受了热停机考验而未发生轴承损坏,并进行了全面的振动考查。NA307型涡轮增压器正处于设计阶段,它采用NA397型增压器中所用的新的Napier“PM”涡轮,并正在签订配套工具合同。首台样机将于2004年春季制成,届时,它将按NA397型增压器的程序完成初期鉴定。通过早期提供理论上的振动分析数据,将进一步加强合作,以保证安装特性得到优化。这一理论随后将由实际试验结果进行验证。这些新的涡轮增压器显示了制造商与用户之间的技术合作是有益的。双方共同开发涡轮增压器能更好地满足发动机的要求,并能保证提交给现场使用的产品首先经过全面验证。这种合作将继续,以研制出可靠的产品设备。

Insight into Dynamics of Hydromagnetic Flow of Micropolar Fluid Containing Nanoparticles and Gyrotactic Microorganisms at Weak and Strong Concentrations of Microelements: Homotopy Analysis Method

American Journal of Computational Mathematics 2022年第2期12卷 267-282页

The mathematical model of bioconvection flow of micropolar fluid through a vertical surface containing nanoparticles and gyrotactic microorganisms is presented in this study. In the study, weak and strong concentrations of microstructures are explored. In the energy and concentration equations, the Catteneo-Christov diffusion models are used to explain temperature and concentration diffusions with thermal and solutal relaxation durations, respectively. The governing equations describing the fluid flow are transformed and parameterized through similarity variables. The approximate analytical solution is obtained by using Homotopy Analysis Method (HAM). The impacts of relevant parameters on the various distributions are investigated and illustrated. It is discovered that increasing the value of the micropolar parameter results in an increase in the microrotation distribution for strong concentrations of microstructures while decreasing the microrotation distribution for weak concentrations of microstructures.

Introduction: Thoracoscopy is a video-assisted surgical approach that mirrors the techniques used in thoracotomy. Our aim is to map the current state of thoracoscopy practice in Cameroon’s hospitals. Methods: This was a descriptive study that collected both retrospective and prospective data over 57 months across four hospitals in Cameroon. It included 13 patients and focused on variables such as socio-demographic factors, clinical profiles, surgical procedures, and postoperative follow-up. Results: Thirteen patients, predominantly male (84.6%, n = 11), with a mean age of 37.5 ± 16 years, were enrolled. Alcohol use (61.5%) and smoking (38.5%) were the most common past histories. The major complaints were dyspnea (84.6%) and chest pain (58.3%). The primary surgical procedure was clot-free thoracoscopy in 30.8% of cases, mainly for persistent hemothorax (41.8%). Most surgeries were elective (76.9%) and performed under general anesthesia with selective intubation (61.5%). The most common approach was single-port thoracoscopy (U-VATS) (76.9%), with no reported difficulties;however, one intraoperative incident occurred and was successfully treated. Drainage was performed systematically in all patients, and one case required conversion to open surgery. Postoperative complications were minor (Clavien-Dindo grade I) and mainly consisted of pain, with a mortality rate of 15.4%. No significant association was found between risk factors and the occurrence of complications or postoperative mortality. Conclusion: Thoracoscopy, a novel approach in our context, primarily focuses on minor thoracic surgeries.
