OBJECTIVE It was the aim of this study to examine the potential value of cervical length at 11-13 weeks' gestation in the prediction of spontaneous preterm delivery. METHODS This was a screening study for spontaneous preterm delivery in singleton pregnancies from cervical length measured by transvaginal ultrasound at 11-13 weeks' gestation. The performance of screening for preterm delivery by...

BACKGROUND The multiple competing demands of the busy office visit have been shown to interfere with delivery of preventive services. In this study we used physician recommendations for screening mammography to examine the relative importance of physician, patient, and visit characteristics in determining on which patient visits this preventive service will be provided. METHODS Physicians in ...

introduction: designing a tool that can differentiate those at risk of child abuse with great diagnostic accuracy is of great interest. the present study was designed to evaluate the diagnostic accuracy of escape instrument in triage of at risk cases of child abuse presenting to emergency department (ed). methods: the present diagnostic accuracy study performed on 6120 of the children under 16 ...

Background: Colorectal Cancer (CRC) is a serious health problem, and its early detection is crucial for treatment and reducing mortality. Beliefs related to colorectal cancer are an affecting factor in a person’s decision about the CRC Program. The current study aimed at assessing the knowledge, attitude, and practice of healthcare providers regarding colorectal cancer screening based on the He...

OBJECTIVE To investigate the potential value of cerebroplacental ratio (CPR) at 30-34 weeks' gestation in the prediction of adverse perinatal outcome. METHODS This was a screening study in 30 780 singleton pregnancies at 30-34 weeks' gestation. Umbilical artery (UA) and fetal middle cerebral artery (MCA) pulsatility index (PI) were measured and the values were converted to multiples of the me...

Tay-Sachs disease (TSD) carrier screening, initiated in the 1970s, has reduced the birth-rate of Ashkenazi Jews with TSD worldwide by 90%. Recently, several nationwide programs have been established that provide carrier screening for the updated panel of Jewish genetic diseases on college campuses and in Jewish community settings. The goals of this study were to determine the performance charac...

Reflectance retrieval is a key parameter for land cover mapping from hyperspectral imagery. However most of the inverse methods to estimate these reflectances are limited in urban areas with the use of high spatial resolution sensors because they do not take into account the 3D radiative impact of the urban environment. A recent tool, ICARE [1], is able to retrieve surface reflectance in the re...

BACKGROUND Non-invasive prenatal testing (NIPT), also known as cell-free DNA testing and non-invasive prenatal screening (NIPS), is an important addition to the range of screening tests for fetal chromosomal abnormalities. For trisomy 21 in particular, NIPT is superior to other screening modalities. However, NIPT has limitations and complexities that requesting clinicians and their patients sho...

background: the study was conducted to estimate and compare the validity and performance of two screening methods for uri­nary schistosomiasis: the interview - reporting blood in urine- and detecting microhematuria by reagent strip. methods:  in year 2003, 515 schoolchildren from five schools in abyan and taiz governorates in yemen, were in-terviewed by healtworker for hematuria, and then urine...

abstract background assuring safety and survival of blood in vitro depends on anti-coagulation substances, blood bag characteristics, storage conditions, and transport of blood. besides, careful selection and screening of donors as well as blood tests can minimize the transmission risk of blood-transmissible pathogens and optimize blood health. the aim of this study was to assay the level of kn...
