Behavioral studies have identified select experiences that can prime infants to attend to color information as the basis for individuating objects prior to the time they do so spontaneously. For example, viewing pretest events in which the color of an object predicts the function in which it will engage leads 9-month-olds (who typically do not attend to color differences) to demonstrate increas...

Human immunodeficiency virus (HIV) prevention interventions, such as preexposure prophylaxis (PrEP), are often targeted to men who have sex with men (MSM) who self-report high-risk behaviors. Data from a prospective study evaluating methods to detect acute HIV infection among a primarily young (aged <25 years) and black or African American (African American) population from North Carolina were ...

Researchers at the University of Bourgogne in Dijon, France surveyed French geneticists who were members of the "Association Français des Généticiens" on incidental findings (IF) found on array-based comparative genomic hybridization (aCGH) technology retrospectively over a seven-year period.

BACKGROUND Pretest probability (PTP) assessment plays a central role in diagnosis. This report compares a novel attribute-matching method to generate a PTP for acute coronary syndrome (ACS). We compare the new method with a validated logistic regression equation (LRE). METHODS Eight clinical variables (attributes) were chosen by classification and regression tree analysis of a prospectively c...

Background Early detection of loss asthma control can effectively reduce the burden disease. However, broad implementation in clinical practice has not been accomplished so far. We are need research investigating operationalization eHealth pediatric care practice, which provide most potential benefits terms adoption, efficiency, and effectiveness. Objective The aim this study was to investigate...

the aim of the current study was to investigate the effect of paaryaad training program on the development of motor skills of children aged between 6 and 8 who suffered from high function autism (hfa). for this purpose, 30 girls with hfa (mean age 7.1 ± 0.6 yr) were randomly selected from special schools of sanandaj city. then, according to the pretest scores, were assigned to control and exper...

BACKGROUND Abnormal results of diagnostic laboratory tests can be difficult to interpret when disease probability is very low. Although most physicians generally do not use Bayesian calculations to interpret abnormal results, their estimates of pretest disease probability and reasons for ordering diagnostic tests may--in a more implicit manner--influence test interpretation and further manageme...

BACKGROUND When ultrasonography is used to investigate deep-vein thrombosis, serial testing is recommended for those who test negative initially. Serial testing is inconvenient for patients and costly. We aimed to assess whether the calculation of pretest probability of deep-vein thrombosis, with a simple clinical model, could be used to improve the management of patients who present with suspe...

Adding a pretest as a covariate to a randomized posttest-only design increases statistical power, as does the addition of intermediate time points to a randomized pretest-posttest design. Although typically 5 waves of data are required in this instance to produce meaningful gains in power, a 3-wave intensive design allows the evaluation of the straight-line growth model and may reduce the effec...
