Introduction: Exercise stress testing (on a treadmill or ergometer bicycle) is an important test in cardiology for diagnosing myocardial ischemia. This test in Mali is still in its beginning compared to other countries in the sub-region. The lack of data in Mali prompted this study, which aimed to evaluate the indications of this activity and its diagnostic contribution to cardiology in Mali. Materials and Methods: This was a retrospective, descriptive study. The study was conducted at the “TOUCAM” medical clinic in Kati based on the analysis of stress test reports between January 2016 and August 2022. Result: During the study period, we documented 73 patients who underwent exercise testing on a bicycle ergometer for suspected coronary heart disease. The mean age of our patients was 47.5 ± 13.8 years (14 and 79 years). Males accounted for the majority (78.1%). The sex ratio is 3.5. More than half of our patients were overweight or obese (77.1%). Hypertension and diabetes affected 52.1% and 25.8% of patients, respectively. 20.8% of patients had coronary artery disease. renin-angiotensin-aldosterone system blockers (56.8%) and beta-blockers (51.3%). The main indications were chest pain (63.0%) and ischemia detection (15.1%). A modified STEEP protocol was used. The majority of our patients (71.2%) achieved at least 85% of their maximum theoretical heart rate. The main reason for the termination of the study was fatigue (57.3%). The average duration was 11.3 ± 4.2 minutes. 24.7% thought the stress tests were positive and 17.8% thought they were controversial. Conclusion: This study demonstrates the importance of stress testing in the diagnosis and treatment of ischemic heart disease, especially in settings where we have very limited access to coronary angiography.

Introduction. Hyperprolactinemia represents a supraphysiological secretion of prolactin. In clinical practice, it is the most frequently encountered anterior pituitary disorder. However, its real prevalence is little known in Africa. The purpose of this study is to list all cases of hyperprolactinemia over the past four years and to make an inventory of the various etiologies found and their management. Methodology. This is a cross-sectional descriptive study on the files of patients who came for consultation in the internal medicine and endocrinology department with hyperprolactinemia retrospectively collected from January 2017 to December 2020. Included were patients followed or whose the diagnosis of hyperprolactinemia was established in endocrinological consultation during the study period. Results. This study recorded 26 cases of hyperprolactinemia. The female sex represented 73.08% (sex ratio M/F 0.37) and the average age was 33.92 years. The 40 - 50 age group was the most represented with 30.77%. In women, galactorrhea accounted for 73.07%, amenorrhea 57.69% of clinical pictures and infertility 23.08%. In men, infertility accounted for 7.69% of presentations, gynecomastia 11.54% and erectile dysfunction 15.38%. The duration of evolution of the signs was 4 months in 23.08% of the patients. The mean prolactinemia was 702.58 ng/ml. CT was performed in 80.85% of patients. The main etiologies were pituitary adenomas (77%). All our patients were treated with dopaminergic agonists. Cabergoline was prescribed in 77% of patients. The evolution was favorable in 96.25% of patients. Conclusion. Hyperprolactinemia is a pathology that exists in our regions. The main etiology remains pituitary adenomas and treatment with cabergoline.

Introduction: Breast cancer is the most common cancer in women worldwide, accounting for an estimated 22% of all female cancers. It is the leading cause of cancer mortality in women, almost all of which is due to metastases, with 73% of metastases occurring in the bone. In oncology, metastable technetium 99-labelled methylene bisphosphonate bone scintigraphy (BS) remains the standard examination for detecting and assessing the extent of bone metastases. The aim of this study was to assess the role of BS in the evaluation and follow-up of breast cancer in Senegal. Methodology: This was a retrospective study of breast cancer patients who underwent bone scintigraphy with 99mTc-HMDP in the nuclear medicine department of Idrissa Pouye General Hospital (IPGHO), from July 2009 to June 2022. Results: We enrolled 165 patients, mean age 46.79 years (27 - 87 years). BS was performed in 94.37% of cases for post-therapeutic monitoring and in 5.63% for pre-therapeutic assessment. Results were contributory in 131 patients (92.25%), of whom 72 cases (50.70%) were normal and 59 cases (41.55%) positive or presenting bone metastases;and non-contributory or doubtful in 11 cases (7.75%). Secondary bone locations were multiple in 57 cases (96.61%) and single or solitary in 2 cases (3.39%). The scintigraphic appearance of bone metastases was hyper-fixative in 58 cases (98.31%) and mixed in 1 case (1.69%). Bone lesions were quantified using the Soloway’s grading classification. Conclusion: BS with 99mTc-labelled bisphosphonates remains the examination of choice for skeletal exploration, in the detection and extension of bone metastases in breast cancer. Performance has been enhanced by the development of SPECT coupled with CT (SPECT-CT).

[目的/意义]信息通信技术(ICT)政策是引领社会经济转型发展、提升政府治理能力与公共服务的重要战略工具。识别并理解不同地区各级政府对ICT政策采纳与关注的异质性,对于缩小数字鸿沟和促进经济均衡发展至关重要。[方法/过程]文章以1994—2021年中国政府发布的ICT政策为研究样本,基于社会表征理论中动态化、成因化和结构化三维视角探索中央和八大经济区域政府在ICT政策注意力分配的时空差异与影响机制。首先,利用结构化主题模型识别大规模ICT政策中的重要议题,从注意力强度、核心内容和主题协同性三方面量化区域政府在不同ICT政策议题上的注意力分配差异;其次,从动态化视角分析各区域政府对ICT政策注意力分配的演进过程;再次,从成因化视角考察地理位置、发布时间、政策被引次数等因素对ICT政策注意力分配的作用机理;最后,从结构化视角探讨政策类型、政策效力等级、政府行政级别三个因素对不同经济区域对ICT政策注意力分配的调节效用。[结果/结论]中央政府表现出注意力多样性和相对稳定性的特征,而地方政府对议题的关注具有显著优先级和短时热度现象;地理位置、发布时间和政策被引次数显著影响政策议题的注意力分配,其作用机制与议题属性相关;政策类型、效力等级和行政级别从执政理念、政府权力以及制度水平三个方面调节决策群体的注意力分配表征。

[研究目的]基于动态知识流动特征对有向的技术融合关系进行预测,有助于提高企业的研发效率及科技管理部门对科技资源的合理分配。[研究方法]首先,将IPC前4位代码作为技术单元,基于专利中主分类号与副分类号提取技术间的有向知识流动关系;然后,借鉴关联规则挖掘算法从重要性、强度和依赖度3个维度对知识流动关系进行筛选,将满足指标阈值的知识流动关系作为有向技术融合关系;最后,将有向技术融合关系预测转化为有监督的二分类任务,以机器学习算法为模型基础,结合前两个时期的技术间知识流动特征及其时序变化特征,预测下一个时期内的技术间是否存在技术融合关系。[研究结论]增材制造领域的实证分析结果显示,以代价敏感机器学习算法为预测算法,基于前两个时期的技术间知识流动特征及其时序变化特征可以有效预测下一阶段中的技术融合。随着技术的发展,技术间的单向融合愈发频繁,并逐渐演变为技术双向融合,甚至呈现多技术融合的现象。

调蓄水池在施工期遇到滑坡而无法实施,工程建设无法正常推进,这将影响工程建设进度和工程整体建成后的效益发挥。静宁田堡调蓄水池滑坡设计变更后工程将正常施工并早日建成,对早日发挥工程效益起积极作用。设计变更后滑坡治理部位施工主要为抗滑桩工程,产生的土方主要用于调蓄水池筑坝,无多余弃土方,对渣场容量和设置基本无影响,施工征占地的数量稍有增加,施工区也不会由于设计变更而产生生物量的损失,在采取科学措施后将不会产生新的水土流失。

Giant cerebriform nevus cell nevus of the scalp is an extremely rare form of congenital melanocytic nevus. Giant cerebriform nevus of the scalp has a major psychosocial impact because of its unsightly appearance with fetid maceration. We report the case of a 35-year-old woman who had a painless, malodorous swelling of the cerebriform scalp measuring 20 × 17 cm in diameter with a wide base of insertion at the occipital level adhering to the deep planes. The excision associated with a skin plasty was carried out. Histology concluded that there was a giant cerebriform naevo-cellular nevus of the scalp.
