with POTS.Background Impaired heart rate variability (HRV) is associated with increased mortality in sinus rhythm. However, HRV has not been systematically assessed in patients with atrial fibrillation (AF). We hypothesized that parameters of HRV may be predictive of cardiovascular death in patients with AF. Methods and Results From the multicenter prospective Swiss-AF (Swiss Atrial Fibrillation) Cohort Study, we enrolled 1922 patients who were in sinus rhythm or AF. Resting ECG recordings of 5-minute duration were obtained at baseline. Standard parameters of HRV (HRV triangular index, SD of the normal-to-normal intervals, square root of the mean squared differences of successive normal-to-normal intervals and mean heart rate) were calculated. During follow-up, an end point committee adjudicated each cause of death. MLT-748 manufacturer During a mean follow-up time of 2.6±1.0 years, 143 (7.4%) patients died; 92 deaths were attributable to cardiovascular reasons. In a Cox regression model including multiple covariates (age, sex, body mass index, smoking status, history of diabetes mellitus, history of hypertension, history of stroke/transient ischemic attack, history of myocardial infarction, antiarrhythmic drugs including β blockers, oral anticoagulation), a decreased HRV index ≤ median (14.29), but not other HRV parameters, was associated with an increase in the risk of cardiovascular death (hazard ratio, 1.7; 95% CI, 1.1-2.6; P=0.01) and all-cause death (hazard ratio, 1.42; 95% CI, 1.02-1.98; P=0.04). Conclusions The HRV index measured in a single 5-minute ECG recording in a cohort of patients with AF is an independent predictor of cardiovascular mortality. HRV analysis in patients with AF might be a valuable tool for further risk stratification to guide patient management.

This report is an extension of early work, completed by the same authors that described the diagnostic accuracy of a Spanish nonword repetition task. Method One hundred thirty Spanish-speaking families with preschool-age children participated; 37 children had DLD, and 93 were typically developing. Families were recruited from early childhood programs in three states in the western region of the United States. Working memory and linguistic measures were collected from the children; parents completed a vocabulary checklist and reported on their child's longest utterances. Results Nonverbal working memory was not associated with other measures, but verbal working memory was associated with linguistic measures. Although there were no group differences on nonverbal working memory, group differences (DLD vs. typical development) were detected on verbal working memory and linguistic measures. Verbal working memory combined with vocabulary scores resulted in 79% of cases correctly classified. Conclusions Working memory tasks yielded different results depending on the type of task (verbal vs. nonverbal). Outcomes from this study showed that a nonverbal working memory task (hand movement) was not useful in distinguishing preschool-age dual language children with DLD from typical peers, but a verbal working memory task (nonword repetition) may be useful if combined with other more robust linguistic measures.Purpose The purpose of this study was to explore how bilingual children shift sets to gain flexibility when forming categories. Using a cognitive lab approach focused on understanding how learners approach problems, we asked children to sort 10 sets of pictures representing common objects in two different ways and to explain their rationale for the sort. We explored the relationship between age and language use on their performance. Method Forty-six typically developing Spa
