Aim: A clinical study with retrospective analysis of 10 eyes of 5 babies with APROP of birth weight 970 to 1420 grams, Gestational age 26 to 32weeks, from a Level 3 NICU with multiple risk factors. Result: Flat neovascularisation was seen in 8 eyes in zone 1,one eye in zone 2. One eye showed a large vascular loop in zone 2. 3 babies with APROP had very low gestation age <28wks.2 babies were of ...

OBJECTIVE. The purpose of this work was to compare the predictive accuracy of alternative risk-assessment strategies used to screen for the risk of significant neonatal hyperbilirubinemia. PATIENTS AND METHODS.We conducted a prospective cohort study of 823 term and nearterm newborns admitted to the well-infant nursery at the Hospital of the University of Pennsylvania. Maternal, infant, and deli...

STUDY DESIGN Retrospective study. PURPOSE To evaluate the initial fixation using the cortical bone trajectory (CBT) technique for posterior lumbar fusion through assessment of the clear zones around the screws and the risk factors involved. OVERVIEW OF LITERATURE Postoperative radiolucent zones (clear zones) are an indicator of poor conventional pedicle screw fixation. METHODS Between Jan...

STUDY DESIGN A retrospective study using 323 contrast-enhanced, multi-planner three-dimensional computed (3D-CT) scans. OBJECTIVE The aim of this study was to identify risk factors for injury to the major vessels in the lateral transpsoas approach. SUMMARY OF BACKGROUND DATA To avoid critical complications such as major vessel injury, it is essential to examine anatomical information relate...

This paper describes a methodology based on Answer Set Programming (ASP) to work with incomplete geographic data. Source geographic data which describes a risk zone is translated to ASP description and it allows to solve query’s which can not be solved by a normal GIS. An evacuation plan can change when new situations are presented, for instance traffic, a zone in extreme danger or other natura...

OBJECTIVE To investigate risk factors, including reported net use, for Plasmodium infection and anaemia among school children and to explore variations in effects across different malaria ecologies occurring in Kenya. METHODS This study analysed data for 49 975 school children in 480 schools surveyed during a national school malaria survey, 2008-2010. Mixed effects logistic regression was use...

In this paper, we propose two new vision-based methods for irzdooimobile robot navigation. One is a selflocalization algorithm using projective invariant and the other is a method for obstacle detection by simple image difference and relative positioning. Foia geometric model of corridor erzvironnaent, we use natural features formed by floor, walls, and door frames. Using the cross-ratios of th...

This study reports the results of a simulator-based assessment of driver response to two different urban highway work zone configurations. One configuration represented an existing design which was contrasted with a second configuration that presented a reduced taper length prototype work zone design. Twenty-one drivers navigated the two different work zones in two different conditions, one wit...
