Feed-forward Control Nursing Model in Expectant Treatment of Placenta Previa

BACKGROUND We studied the possible advantages of feed-forward control nursing model in the treatment of placenta previa. METHODS We enrolled 60 pregnant women who were receiving treatment for expectant placenta previa between January 2010 and January 2016 and randomly divided them into the control group and the observation group with 30 cases in each group. In the control group, we offered sp...

Placenta previa

OBJECTIVES To review cases of placenta previa in the last 13 years in a tertiary teaching hospital to identify risk factors for maternal morbidity.  METHODS A retrospective analysis of all cases of placenta previa managed at King Abdulaziz University Hospital (KAUH), Jeddah, Kingdom of Saudi Arabia from January 2001 to December 2013.    RESULTS The total number of deliveries was 55,862 deli...

Abnormal Placentation: Placenta Previa, Vasa Previa, and Placenta Accreta.

Placental disorders such as placenta previa, placenta accreta, and vasa previa are all associated with vaginal bleeding in the second half of pregnancy. They are also important causes of serious fetal and maternal morbidity and even mortality. Moreover, the rates of previa and accreta are increasing, probably as a result of increasing rates of cesarean delivery, maternal age, and assisted repro...

Parsimonious learning feed-forward control

We introduce the Learning Feed-Forward Control configuration. In this configuration, a B-spline neural network is contained, which suffers from the curse of dimensionality. We propose a method to avoid the occurrence of this problem. 1 Introduction In order to design a conventional feedback controller, like a state-feedback controller, detailed knowledge of the process under control is required...

Effect of Placenta Previa on Preeclampsia

BACKGROUND The correlation between gestational hypertension-preeclampsia (GH-PE) and placenta previa (PP) is controversial. Specifically, it is unknown whether placenta previa has any effect on the various types of preeclampsia (PE), and the role PP with concurrent placenta accreta (PA) play in the occurrence of GH-PE are not well understood. OBJECTIVE The aim of this study was to identify th...
