Predictors and outcome of obstetric admissions to intensive care unit: A comparative study

This descriptive observational study was carried out in Guru Teg Bahadur Hospital to identify predictors and outcome of obstetric admission to Intensive Care Unit (ICU). Ninety consecutive pregnant patients or those up to 42 days of termination of pregnancy admitted to ICU from October 2010 to December 2011 were enrolled as study subjects with selection of a suitable comparison group. Qualitative statistics of both groups were compared using Pearson′s Chi-square test and Fisher′s exact test. Odds ratio was calculated for significant factors. Low socioeconomic status, duration of complaints more than 12 h, delay at intermediary facility, and peripartum hysterectomy increased probability of admission to ICU. High incidence of obstetric admissions to ICU as compared to other countries stresses on need for separate obstetric ICU. Availability of high dependency unit can decrease preload to ICU by 5%. Patients with hemorrhagic disorders and those undergoing peripartum hysterectomy need more intensive care

Neutron stars in a Skyrme Model with Λ hyperons

In order to calculate neutron-star properties, it is necessary to have an Equation of State (EOS) linking pressure to the total energy density of the dense matter. At densities closer to the the nuclear saturation density (ρ 0 = 0.17f m −3 ), the matter is mostly composed of neutrons, protons and leptons (electrons and muons) in β equilibrium. As density increases, new hadronic degrees of freedom may appear. Hyperons are one of them as the equilibrium conditions in neutron stars makes the formation of hyperons energetically favorable. The role of hyperons on the neutron star properties have been studied by several authors (see, e.g. Refs. In this paper, we employ the best fit ΛN interactions obtained by us In our calculations of the EOS we have closely followed the methods reported in Ref
