Herein, we propose a Spearman rank correlation-based screening procedure for ultrahigh-dimensional data with censored response cases. The proposed method is model-free without specifying any regression forms of predictors or variables and robust under the unknown monotone transformations these variable predictors. sure-screening rank-consistency properties are established some mild regularity c...

BACKGROUND Linear and angular measurements such as A point, nasion, B point (ANB) angle and Wits appraisal index are not accurate enough to evaluate sagittal relationship of the jaws. The aim of this study was to evaluate and compare the range of μ and β angles in 6-17-year-old children of Isfahan, having normal occlusion. MATERIALS AND METHODS This was an analytical descriptive study. For th...

BACKGROUND Traditionally, technical proficiency for spinal anesthesia has been assessed using observational scales such as global rating scales or task specific checklists. However more objective metrics are required in order to improve novice's training programs. The aim of this study is to validate the hand motion analysis of the Imperial College Surgical Assessment Device (ICSAD) in a simula...

BACKGROUND Bioelectrical Impedance (BIA) derived phase angle is increasingly being used as an objective indicator of nutritional status in advanced cancer. Subjective Global Assessment (SGA) is a subjective method of nutritional status. The objective of this study was to investigate the association between BIA derived phase angle and SGA in advanced colorectal cancer. METHODS We evaluated a c...

Increasing the precision of measurements of total energy expenditure in population-based epidemiological studies is important for accurately quantifying the relationship between this exposure and disease. Current questionnaire-based methods cannot accurately quantify total energy expenditure, although they may provide an estimate of the frequency of vigorous activities. Heart rate monitoring wi...

STUDY OBJECTIVES Sarcoidosis is a granulomatous disorder primarily affecting the lung, but with frequent extrapulmonary organ involvement. There are no comprehensive scoring systems for sarcoidosis disease severity. Our goal was to develop and validate an objective and comprehensive sarcoidosis disease severity scoring system. DESIGN Three sarcoidosis experts reviewed clinical data on 104 pat...

This study was carrying out to recognize the essential factors for deployment of knowledge management in teaching hospitals affiliated to Qom University of Medical Sciences (QUMS), Iran. Materials and Methods: This descriptive-correlational study was operated on 570 employees o...

OBJECTIVE To determine the indication of routine transrectal ultrasound-guided needle biopsy (TRUSBx) of the prostate gland following incidental cancer diagnosis after transurethral resection of the prostate (TURP) for benign prostatic hyperplasia. MATERIALS AND METHODS A multi-institutional search identified 63 patients with incidental TURP-diagnosed prostate cancer from 2001 to 2010, who un...

Purpose:MUC4 shows aberrant expression in early pancreatic lesions and ahigh specificity for pancreatic cancer. It thus has ahighpotential tobe a sensitive and specific biomarker.Unfortunately, its low serum level limits its diagnostic/prognostic potential.We here report that amultifaceted acute phase protein lipocalin 2, regulated by MUC4, could be a potential diagnostic/prognostic marker for ...
