The objective of this work is to contribute to the management of OF cases in CAR. Patients and Methods: This was a retrospective, descriptive and analytical study, including data from several OF care services. The study included 245 cases of OF, operated on from 2009 to 2018. The parameters studied were maternal and obstetrical data, sociodemographic data, the specific characteristics of the fistulas as well as the modalities and outcome of surgical treatment. The data collected came from six (6) OF surgical repair campaigns organized by the Ministry of Health and Population with the support of UNFPA. Results: We recorded 245 patients, representing a prevalence of 0.77% of OF per year. Among these patients, almost half (45.3%) were treated at the Sino-Central African Friendship University Hospital Center (CHUASC). The average age of the patients was 30 years (range 14 to 78 years). They were unschooled (53.9%) and primigravidas (35%). The fistulas had an average duration of evolution of 7.58 years. They were vesicovaginal in 25.3%. Types V and I dominated in 17.4% and 9.2%, respectively. In 85.9% of cases, fistulorrhaphy was performed, half of which (50.2%) via the upper route. The cure rate was 83.3%. Note that our study reveals statistically significant links between the evolution after surgery with age (p = 0.04 Conclusion: OF mainly affected women of childbearing age, uneducated, primiparous. Vesicovaginal fistula was the frequently encountered type and was manifested by urine loss clinically with a positive methylene blue test.展开更多

The evolutionary aspects of the incidence of antibiotic resistance in Salmonella strains no longer seem to attract much interest in the Central African Republic (CAR), although salmonellosis remains a health problem requiring national and international surveillance. Methodology: The study conducted at the National Laboratory of Clinical Biology and Public Health, Bangui, Central African Republic (LNBCSP) was a retrospective descriptive study. The study duration was five years (January 2019 to December 2023). The study sample consisted of patients who underwent bacteriological testing of stool, blood and urine samples for Salmonella at the LNBCSP in Bangui during this period. Study variables were age, sex, year and bacteriological test results. Statistical tests were used to compare incidences. Relative risks (RR) were calculated to measure the degree of association. Results: From 2019 to 2023, we recorded 353 Salmonella strains, of which 5% were found in blood, 37% in urine and 58% in stool. Patient age ranged from 1 to 86 years, with a mean of 27 ± 22.05 years and a mode of 5 years. Children aged 0 to 14 years (34%) and females (55.81%) predominated. The highest rate of contamination by Salmonella strains was 1.69% in 2022. The overall incidence of salmonellosis was 6.72 in 2019, 7.05 in 2020, 6.91 in 2021, 16.9 in 2022 and 6.26 in 2023 per 1000 samples. Resistance was 30.47% to β_lactam antibiotics, 24.22% to fluroquinolones and 37.97% to Salmonella spp. For Salmonella arizonae strains, resistance was 20.25% to aminoglycosides, 43.67% to chloramphenicol and 7.59% to imipenem. Conclusion: Laboratory-based surveillance of antibiotic resistance in Salmonella strains is needed in both human and veterinary medicine. Another study based on molecular characterization will identify new antibiotic-resistant variants circulating in CAR.展开更多

Then, the comparison on calculation methods of bending behavior including the original Chinese calculation method, the present Chinese calculation method, the present American calculation method and the present European calculation method is studied. The results show that the original Chinese calculation method of bending behavior is based on the allowable stress calculation method, and the design safety factors are 3.55 to 4. 0. In term of the calculation area of longitudinal rebars of reinforced concrete beams, without considering earthquake action, the original Chinese structural calculation method is safer than the present Chinese structural calculation method, the present European structural calculation method, and the present American structural calculation method. The results can provide support for the structural safety assessments of modem Chinese reinforced concrete buildings.展开更多

Thus ＂NTBF＂ （New Technology Based Firms） are increasingly developing, that are able to act both as a major player in the innovation process, and as a link between the market and the production world and that need not only venture capital to cope with the large initial investment, but also such figures that, with their leadership qualities, are able to anticipate the market development. As a result, the emergence of the knowledge society has increasingly driven companies to search for new business figures, playing both the role of financing partners and of valuable support to the entrepreneur in running a business. Such distinguishing characteristics appear to be peculiar to the figure of the business angel that, thanks to the know-how and international contacts, acts not only as a simple partner but also as a leading force within the company, who is able to simplify the decision process of the business and drive it to plan profitable investment and winning strategies. Therefore, the present work is aimed at understanding how such a figure is crucial to the development of new companies operating in emerging economies being, as well, technologically advanced, as it is the case for Estonia, which is called the ＂Silicon Valley of the Baltic Sea＂. Thus, the work will first focus on the functions, organization and the benefits resulting from the involvement of business angels and, secondly, on the reasons why this figure is preferable to other operators involved in venture capital, namely venture capitalists. Finally, the good practices implemented in Europe by the various associations of business angels will be analyzed, paying particular attention to the Italian context, in order to consider the opportunity to develop, even in the Baltic Republics area, a similar institution being able to ensure, by promoting contact between entrepreneurs and business angels, the proper development of businesses, especially starting-up companies.展开更多

文摘The world entrepreneurial scenery, being under constant evolution because of globalization and the current international crisis, has changed corporate competition, requiring companies to meet such key-factors to success as increased organizational flexibility and innovative development of their structures and products. Thus ＂NTBF＂ （New Technology Based Firms） are increasingly developing, that are able to act both as a major player in the innovation process, and as a link between the market and the production world and that need not only venture capital to cope with the large initial investment, but also such figures that, with their leadership qualities, are able to anticipate the market development. As a result, the emergence of the knowledge society has increasingly driven companies to search for new business figures, playing both the role of financing partners and of valuable support to the entrepreneur in running a business. Such distinguishing characteristics appear to be peculiar to the figure of the business angel that, thanks to the know-how and international contacts, acts not only as a simple partner but also as a leading force within the company, who is able to simplify the decision process of the business and drive it to plan profitable investment and winning strategies. Therefore, the present work is aimed at understanding how such a figure is crucial to the development of new companies operating in emerging economies being, as well, technologically advanced, as it is the case for Estonia, which is called the ＂Silicon Valley of the Baltic Sea＂. Thus, the work will first focus on the functions, organization and the benefits resulting from the involvement of business angels and, secondly, on the reasons why this figure is preferable to other operators involved in venture capital, namely venture capitalists. Finally, the good practices implemented in Europe by the various associations of business angels will be analyzed, paying particular attention to the Italian context, in order to consider the opportunity to develop, even in the Baltic Republics area, a similar institution being able to ensure, by promoting contact between entrepreneurs and business angels, the proper development of businesses, especially starting-up companies.
