Differentiating Characteristics and Responses to Treatment of New-Onset Heart Failure With Preserved and Reduced Ejection Fraction in Ambulatory Patients.

Background: Differences in clinical presentation and therapy outcomes between heart failure with preserved ejection fraction (HFpEF) and heart failure with reduced ejection fraction (HFrEF) have been reported but described mainly among hospitalized patients. Because the population of outpatients with heart failure (HF) is increasing, we sought to discriminate the clinical presentation and responses to medical therapy in ambulatory patients with new-onset HFpEF vs. HFrEF.

Early Prediction and Evaluation of Risk of Autism Spectrum Disorders.

Autism is a neuro-developmental condition that first appears at less than three years of age. Autism spectrum disorders (ASD) include several symptoms, such as social communication impairment, stereotyping behaviors, speech abnormalities, and impairment of eye contact. Its prevalence has increased recently, and several factors play a role in increasing the risk of autism.
