OBJECTIVES To describe changes over time in extent of idiopathic pulmonary fibrosis (IPF) at multidetector computed tomography (MDCT) assessed by semi-quantitative visual scores (VSs) and fully automatic histogram-based quantitative evaluation and to test the relationship between these two methods of quantification. METHODS Forty IPF patients (median age: 70 y, interquartile: 62-75 years; M:F...

Dental calcification is a biological phenomenon used to estimate the maturation status of growing children. The effect body mass index percentile (BMI-percentile) on this process appears contentious among researchers. To determine predictive mandibular canine calcification. A prospective descriptive cross-sectional study. This was cross sectional study comprising eighty four participants (5-17 ...

This study offers a new technique for constructing percentile bootstrap intervals to predict the regression of univariate local polynomials. Bootstrap uses resampling derived from paired and residual methods. The main objective this is perform comparative analysis between two methods by considering nominal coverage probability. Resampling nonparametric with return method, where each sample poin...

BACKGROUND Upper arm postures are believed to be an important risk determinant for musculoskeletal disorder development in the neck and shoulders. The 10th and 90th percentiles of the angular elevation distribution have been reported in many studies as measures of neutral and extreme postural exposures, and variation has been quantified by the 10th-90th percentile range. Further, the 50th perce...

OBJECTIVE To describe the characteristics of sustained improved nutritional outcomes through the use of quality improvement (QI) methodology. DESIGN Retrospective analysis of a QI intervention in two institutions, implemented as part of larger national collaboratives. SETTING Paediatric cystic fibrosis (CF) programmes in academic centres in Alabama and Illinois. PARTICIPANTS All paediatri...

INTRODUCTION Sepsis-related multiple organ dysfunction is a common cause of death in the intensive care unit. The effect of sepsis on markers of tissue repair is only partly understood. The aim of this study was to measure markers of collagen synthesis and degradation during sepsis and investigate the association with disease severity and outcome. METHODS Forty-four patients with severe sepsi...
