This is a review of the first 10 coronary artery bypass surgeries performed by the local team. The mean age was 62 years old [45 - 74]. The patients were predominantly male, with a M/F ratio of 4:1. Cardiovascular risk factors were mainly myocardial infarction (MI) (60%), hypertension (50%), obesity (40%) and diabetes (30%), with at least two risk factors per patient. Angina was the main symptom (80%). The average time from presentation to surgery was 8 months. The mean Euroscore 2 was 2.92 ± 1.65 [1.33 - 6.60]. Coronary angiography revealed an average of 2 lesions per patient, with 3-vessel involvement in 70% of cases: the Interventricular artery (IVA) (100%), the right coronary artery (90%) and the circumflex artery (70%). On echocardiography, the mean Left ventricular ejection fraction (LVEF) was 59% [33% - 76%]. All patients underwent median sternotomy with bypass grafting. The average duration of the cardiopulmonary bypass was 150 min [46 - 275 min];that of aortic clamping, 120 min [43 - 232 min]. The grafts used were internal thoracic artery (ITA) in 100% of cases (80% on the left and 20% on the right), and the great saphenous vein (GSV) in 60% of cases (50% on the left and 10 on the right). Double bypass was performed in 60% of cases, single bypass in 30% and triple bypass in 10%. The bypasses were performed on the IVA (100%), the middle lateral of the circumflex (30%) and the bisector (20%). The average time to extubation was 11 hours and the length of stay in the intensive care unit was 7 days [03 - 17 days]. One patient had a reoperation on Day 0 post-op. The average hospital stay was 13 days [06 - 27 days]. Complications occurred in nine of the patients (90%), with a predominance of infectious and neurological complications. Overall operative mortality was 3%, all in intensive care.

地缘破碎带是全球冲突和大国竞争的主要区域,具备外部挤压性、内部分裂性、过程动态性等基本特征,是域内外双重尺度作用下共同形成的地理区域。地缘破碎带的基本特征与发展模式契合于地缘环境研究的核心理念,在地缘环境视角下,地缘破碎带是一个以域内外多元行为体互动实践为核心的不断发展演化的地理区域。通过互动实践,破碎带产生的决策信息集成为制约相关行为体发生行动的物质性与理念性因素,在此约束下,这些决策行动在时序上的排列关联构成了破碎带历史演进的核心内容。选取亚欧交界处的南高加索地区为研究区域,自1991年南高加索三国独立以来,该地区历经复杂的内部冲突与外部博弈,是地缘破碎带分析的典型案例。本文构建出地缘环境视角下地缘破碎带历史演进的分析框架,从本底要素、关联要素、结构要素3类视角解析1991年南高加索地区三国独立后至2020年底的历史演进过程及阶段性特征,并从跨领域互动、跨尺度耦合和多元行为体博弈3方面分析推动演进的内在路径,以地缘政治学理论视角多维化呈现地缘破碎带的历史演进过程,尝试将地理学研究的区域性、综合性、尺度性等基本思维模式融入历史学与国际关系学研究中。

From Fostering to Delusional Disorder of Filiation

引用

Open Journal of Psychiatry 2024年第4期14卷 283-286页

作者： Momar Camara Wissem Masmoudi El Hadji Makhtar ba Sokhna Seck Maïmouna Dieye Aïda Sylla Department of Psychiatry and Medical Psychology Cheikh Anta Diop University Dakar Senegal Thiaroye National Psychiatric Hospital Center Dakar Senegal Fann National University Hospital Center Dakar Senegal Albert Royer Childrens Hospital Dakar Senegal

Introduction: Fostering is a widespread practice in West Africa. It played an essential role in the circulation of children. The failure of its community regulation, not compensated by a legal framework, has made its practice precarious. Observation: A case study was conducted on Dior, who was hospitalised in a psychiatric ward for a delusional disorder of filiation. Dior was entrusted to her maternal grandmother and aunt at ages 2 and 9. During these fosterings, the place of the symbolic father was not substituted, causing a void that challenged her imagination. The outcome was an inscription in a genealogy where she had found herself with prestigious parents. Discussion: Fostering has strongly disrupted the family dynamics in Dior’s case. One of her options was to assume the paternal function, the use of which was perceived as a defiance or even a transgression. This same function would be a starting point of a psychosis whose filial character would only be an attempt at rectification where reality and imagination collide. Conclusion: Our study reveals the importance of stable parental figures at stake in fostering contexts, which constitute a risk factor for the development of a subsequent psychosis.

Removal of Dyes in Aqueous Media with Hydrochar base of Solid Tanneries Waste: Optimization Process and Application

引用

Materials Sciences and Applications 2024年第7期15卷 168-185页

作者： Abdoul Ntieche Rahman Gervais Ndongo Kounou Sakué Ngankam Eric Tamafo Fouegue Aymard Didier Kouotou Daouda Abdelaziz baçaoui Department of Chemistry Higher Teacher Training College Bertoua The University of Bertoua Bertoua Cameroon Department of Fundamental Sciences Institute of Wood Technology of Mbalmayo University of Yaound I Balmayo Cameroon Department of Chemistry Faculty of Science Semlalia University of Cady Ayyad Marrakech Morocco

The Response Surface Methodology (RSM) was used to optimise the conditions of preparation of activated hydrochar from tannery solid waste by hydrothermal carbonisation (HTC). The main factors such as residence time, moisture content and final carbonisation temperature were investigated during the optimisation of hydrochar preparation conditions. The three responses investigated are hydrochar yield, iodine and methylene blue indices. The results of experimental analyses showed that the yield of hydrochar decreases with increasing final temperature, leading to the formation of micropores inside the carbonaceous solid. The optimum conditions for preparing the following hydrochar were obtained: 83.10%, 390.44 mg∙g−1 and 259.63 mg∙g−1 respectively for the hydrochar yield, the iodine and methylene blue indices. The specific surface area of prepared hydrochar is 849.160 m2/g, SEM micrographs showed a porous heterogeneous surface and particularly, the hydrochar surface also revealed external pores on the hydrochar surface which acted as a pathway to the micropores. Fourier transform infrared (FTIR), however, showed a predominance of acid functions on the surface of the carbonaceous solids. Tests were carried out to eliminate indigo carmine in aqueous media. Activated hydrochar showed a high level of activity, with the Langmuir and Freundlich isotherms giving an adsorption quantity of 354.610 mol/g and a KF constant of 468.2489, respectively. The findings of the research revealed that hydrochar produced is well adapted for dyes removal.
