Numerical experiments show that three types of signal couplings are in the same direction. Among them, normal signal coupling is the strongest, followed by that of premature ventricular contractions, and that of atrial premature beats is the weakest. The T test shows that the entropies of the three signals are distinct. Symbolic transfer entropy requires less data, can distinguish the three types of signals and has very good computational efficiency.展开更多

In Ethiopia, where maternal mortality is still high, the maternal and fetal outcomes in PROM is very important to decrease maternal and child mortality and for better management and prevention of complications. Thus, this study aimed to detect the maternal and fetal outcomes and associated factors in term PROM at Mizan-Aman General Hospital, south-west Ethiopia.METHODS: A retrospective cross sectional study was conducted using data available at MizanAman General Hospital during a period of 3 years(January 2011 to December 2013). We examined records of 4 525 women who gave birth in the hospital; out of these women, 185 were diagnosed with term PROM and all of them were included in the study. The data of these women were collected using a checklist based on registration books. The data were analyzed using SPSS version 20.0 statistical package. The association between independent and dependent variables was assessed by bivariate and multiple logistic regression analyses. 95%CI and P value less than 0.05 were considered statistically signifi cant.RESULTS: Of the 4 525 women who gave birth in the hospital, 202 were complicated by term PROM. About 22.2% of the women showed unfavorable maternal outcomes. The most common cause of maternal morbidity and mortality was puerperal sepsis. About 33.5% of neonates experienced unfavorable outcomes. The duration of PROM >12 hours(AOR=5.6, 95%CI 1.3–24.1) latency >24 hours(AOR=2.8, 95%CI 1.7–11.8), residing in rural areas(AOR=4.2, 95%CI 3.96–29.4) and birth weight less than 2 500 g were associated with unfavorable outcomes.CONCLUSION: Women residing in rural areas, long latency, and neonates with birth weight less 2 500 g may have unfavorable outcomes. Therefore, optimum obstetric and medical care is essential for the reduction of the devastating complications related to disorders.展开更多
