We recently found that older adults show reduced learning rates when learning a new pattern of coordinated rhythmic movement. The purpose of this study was to extend that finding by examining the performance of all ages across the lifespan from the 20 s through to the 80 s to determine how learning rates change with age. We tested whether adults could learn to produce a novel coordinated rhythm...

Study Design Retrospective study. Objective To compare clinical outcomes, radiographic evaluations including bony union rate and incidence of osteoporotic vertebral fractures (OVFxs), and perioperative complications following posterior lumbar interbody fusion (PLIF) between patients ≥80 years of age and those <80 years. Methods Ninety-six patients ≥70 years old who underwent PLIF were reviewed....

BACKGROUND The measurement of carbohydrate antigen 19-9 (CA 19-9) is recommended for the diagnosis and follow-up of pancreatic cancer. However, increased CA 19-9 has also been reported in patients with various benign diseases of the lung. We aimed to elucidate the pulmonary radiographic abnormalities and laboratory results associated with increased concentrations of CA 19-9. METHODS This stud...

Normative data for 884 neurologically normal adults (15-93) are provided for a six-trial administration of Form 1 of the Spanish version of the Verbal Selective Reminding Test (VSRT). Form 2 was also administered to 391 adults (18-87). Age was the most important predictor of performance on all VSRT scores in Forms 1 and 2. Additionally, women and higher educated participants outperformed men an...

AIMS The main aim of this study was to describe the age at which pathological aortic root dilation occurs in patients with Marfan's syndrome (MFS). METHODS AND RESULTS A total of 160 patients with MFS attending a regional cardiac centre were reviewed retrospectively. Dilation of the ascending aorta was diagnosed by comparing the maximum aortic sinus measurement with control data from the lite...

OBJECTIVE To study the prevalence of atrial fibrillation (AF) and the relation with its risk factors in China. METHODS A total of 19 363 participants (8635 males and 10 728 females) aged ⋝35 years in geographically dispersed urban and rural regions of China were included in this cross-sectional survey. All participants received questionnaire, physical and blood examination. Echocardiography w...

Problems in suppressing neural activity related to distracting information increase with age. We investigated whether age-related changes in processing non-target material are present even when behavioral performance is matched between age groups. Younger (19-36 years) and older (61-80 years) participants performed a go/nogo task with different degrees of cognitive interference for two types of...
