This study aimed to assess expectant management of PPROM before 34 weeks at the university hospital of Kinshasa. We conducted a retrospective analysis of expectantly managed PROM before 34 weeks between January 2008 and December 2018. Maternal and fetal outcomes were collected, and all data were analyzed using the SPSS 23.0 software. Of the 113 patients included in the study, 2.6% were diagnosed with PROM before 34 weeks. We observed prolongation of the pregnancy duration;the median latency period was eight days, and the average gestational age at delivery of 32.85 ± 2.5 weeks. Chorioamnionitis (23%), severe oligoamnios (7%), and acute fetal distress (4%) were complications observed during the latency period. In the postpartum period, endometritis (6.2%), neonatal jaundice (39.8%), anemia (25.7%), ulcerative necrotizing enterocolitis (6.2%), cerebromeningeal hemorrhage (5.3%), and acute respiratory distress syndrome (4.4%) were complications observed. The risk of infection during the latency period was significantly associated with irregular (P = 0.045) or lack (P = 0.006) antenatal care (ANC) attendances and C-Reactive Protein (CRP) results 6 (P = 0.013). The risk of neonatal death was significantly associated to infection during the latency period (P = 0.011), irregular (P = 0.009) or lack of ANC (P = 0.000) attendances, Birth weight g (P = 0.039) as well as Gestational age at birth between 28 to 30 Weeks (S) (P = 0.021). These findings report first-time pregnancy outcomes related to the management of PPROM before 34 weeks in our setting. We found that the conservative attitude adopted allowed the prolongation of pregnancies, reducing the risks associated with prematurity. Nevertheless, attendance in good quality ANC could reduce the frequency of PROM and related adverse outcomes.展开更多

It would be a significant way that enterprises undertake R&D activities for a change. This paper is based on the Shanghai and Shenzhen A-share listed heavy pollution enterprises in 2011-2016, which is based on the review and summary of research results of former researchers, combining with current environmental regulation situation of our country, raising the relevant hypothesis between environmental regulations, R&D investment and business performance against heavy pollution industry. Adopting the method of empirical research, it also built the linear regression model which employs the relevant financial data of heavy-polluting enterprises in China as the statistical research sample. The relationship for heavy-polluting enterprises affected by environmental regulations between environmental protection R&D investment and enterprise business performance was tested. The results show that there is a positive influence on the environmental R&D investment and business performance, and a lag effect upon the R&D investment of enterprises to business performance. Finally, the research results were used to evaluates problems existing in the R&D investment on pollution industry in China as well as business performance and we put forward some suggestions on improving environmental regulation standards and technology innovation consciousness as well as optimizing the structure of R&D investment.展开更多
