Introduction: Several factors influence women’s decision to take First Trimester Screening (FTS) tests. These factors are associated with the ambivalence of women toward undergoing screening tests.  Objective: This study aimed to investigate the effect of Shared Decision-Making (SDM) about undergoing FTS on Decisional Conflict (DC) immediately after consultation and uptake of FTS. Materials a...

OBJECTIVE To evaluate the rate of abnormal results of repeated screening tests for gestational diabetes mellitus when initial tests were normal and related factors. SUBJECTS Six hundred women who had clinical risk factors for gestational diabetes mellitus (GDM) who attended the antenatal care clinic at Siriraj Hospital before 24 weeks of gestation, between January and June 2005 were recruited...

The purpose of prenatal diagnosis tests is insisting of diagnosis of neonatal disorders, preparing a range of informed choices and making couples at risk to be ready for having children with genetic disorders as well. The aim of this article is to investigate all of the tests in order to determine the best one which has the lowest risk and the highest sensitivity. Screening tests (maternal bloo...

BACKGROUND The transtheoretical model (TTM) has been widely used to promote healthy behaviors in different groups. However, a questionnaire has not yet been developed to evaluate the health behaviors that medical practitioners often consider in individuals with cancer or at a high risk of developing cancer. PURPOSE The aim of this study was to construct and validate the Health Behavior and St...

Disease screening is a fundamental part of health care. To evaluate the accuracy of a new screening modality, ideally the results of the screening test are compared with those of a definitive diagnostic test in a set of study subjects. However, definitive diagnostic tests are often invasive and cannot be applied to subjects whose screening tests are negative for disease. For example, in cancer ...

An international collaborative study on serotyping and antimicrobial susceptibility testing of eight Salmonella enterica strains was performed to enhance the capacity of national and regional reference laboratories in WHO Global Salm-Surv to conduct Salmonella serotyping and antimicrobial susceptibility testing. A total of 103 laboratories in 60 countries participated. For serotyping, 78% of th...

Recent international efforts to sequence the human genome have greatly enhanced our ability to test definitively for many genetic conditions. For many, this has been welcome, allowing the diagnosis of disorders that have been previously only suspected. This has also led to the advent of the ‘unpatient’ [1], where there is an increasing ability to test healthy individuals for genetic conditions ...

In 1990, CAST (classification of audiograms by sequential testing) was proposed and developed as an automated, innovative approach to screening infant hearing using a modified Bayesian method. The method generated a four-frequency audiogram in a minimal number of test trials using VRA (visual reinforcement audiometry) techniques. Computer simulations were used to explore the properties (efficie...

OBJECTIVE To study physicians' beliefs about the effectiveness of different tests for cancer screening. METHODS Data were examined from the Women's Health Survey of 1574 Family Medicine, Internal Medicine, and Obstetrics-Gynecology physicians to questions about their level of agreement about the clinical effectiveness of different tests for breast, cervical, ovarian, and colorectal cancer scr...
