AIM To determine whether patient triggered ventilation (PTV) leads to greater exposure to significant hypocarbia than conventional ventilation (CMV) in premature infants during the first 72 hours of life. METHODS Infants of 32 weeks gestation or less were included. Randomisation yielded 74 infants on PTV and 68 infants on CMV. Arterial PaCO(2) measurements were taken four hourly for the first...

Phylogenetic relationships inferred from multilocus organellar and nuclear DNA data are often difficult to resolve because of evolutionary conflicts among gene trees. However, conflicting or "outlier" associations (i.e., linked pairs of "operational terminal units" in two phylogenies) among these data sets often provide valuable information on evolutionary processes such as chloroplast capture ...

Fast image codecs are a current need in applications that deal with large amounts of images. Graphics Processing Units (GPUs) suitable processors to speed up most kinds algorithms, especially when they allow fine-grain parallelism. Bitplane Coding Parallel Coefficient processing (BPC-PaCo) is recently proposed algorithm for the core stage wavelet-based tailored highly parallel architectures GPU...

BACKGROUND Cystic fibrosis (CF) is the most common life threatening autosomal recessive disorder in the white population. Wasting has long been recognised as a poor prognostic marker in CF. Whether it predicts survival independently of lung function and arterial blood gas tensions has not previously been reported. METHODS 584 patients with CF (261 women) of mean (SD) age 21 (7) years were stu...

The estimation of plasma hemoglobin concentration (Hb) is among one of the daily activities in the practice of clinical anesthesiology. The near-infrared spectroscopy of the brain (rSO(2)) represents a balance between cerebral oxygen delivery and consumption. This study was designed to assess the value of rSO(2) in the prediction of the Hb level while other variables were mathematically control...

In cross-national data on individual and country-level characteristics, the variance of log annual income is shown to correlate positively with indicators of redistribution. The database comes from the Panel Comparability (PACO) project, affiliated with the Luxembourg Income Study (LIS), a first effort to provide comparable panel data across a broad range of countries. Countries in the sample i...

A b st ra ct Background and Aims: To identify predictors of need of mechanical ventilation (MV) and that of reintubation, after a planned extubation, among the patients with exacerbation of chronic obstructive pulmonary disease. Materials and Methods: Prospectively collected data of 82 patients with exacerbation of COPD over a one-year period were reviewed. Clinical and demographic profile, APA...
