EP19.03: Cerebroplacental ratio (CPR) curve reference based on local pregnant population is more efficient than external CPR curve to predict operative delivery in appropriate‐for‐gestational‐age fetuses

The value of biophysical profile and sonographic cerebroplacental ratio (CPR) in predicting childbirth mode and adverse neonatal outcomes

Efficient elliptic curve cryptosystems

Elliptic curve cryptosystems (ECC) are new generations of public key cryptosystems that have a smaller key size for the same level of security. The exponentiation on elliptic curve is the most important operation in ECC, so when the ECC is put into practice, the major problem is how to enhance the speed of the exponentiation. It is thus of great interest to develop algorithms for exponentiation...

Bystander-initiated chest compression-only CPR is better than standard CPR in out-of-hospital cardiac arrest

INTRODUCTION Out-of-hospital cardiac arrest has a low survival rate to hospital discharge. Recent studies compared a simplified form of CPR, based on chest compression alone versus standard CPR including ventilation. We performed systematic review and meta-analysis of randomized controlled trials, focusing on survival at hospital discharge. METHODS We extensively searched the published litera...

A new population-based reference curve for symphysis-fundus height.

OBJECTIVE To present a new gestational-age-specific percentile curve for symphysis-fundus (SF) height and to determine the effects of maternal and fetal covariates. DESIGN A population-based register study. SETTING Antenatal clinics in Västra Götaland County, Sweden, between 2005 and 2010. POPULATION A total of 42 018 women with ultrasound-dated singleton pregnancies who delivered at Sahl...

A dose-response curve for the negative bias pressure of an intrathoracic pressure regulator during CPR.

An intrathoracic pressure regulator (ITPR) is a device that can be added to the external end of a tracheal tube to create controlled negative airway pressure between positive pressure ventilations. The resulting downward bias of the airway pressure baseline promotes increased venous return and enhanced circulation during CPR and also during hypovolemic shock. In the present study, we exercised ...
