38% as shown in Table 1 in my article.2 I apologize for this error. Their findings,1 coupled with the other reports of the mortality of untreated PE,3–6 would indicate that the mortality of untreated PE is approximately 30%. Given the fact that the mortality of PE in patients treated with heparin and warfarin is 5%,7,8 it is unlikely that there will be additional randomized clinical trials comp...

BACKGROUND The increased use of computed tomography pulmonary angiography (CTPA) is often justified by finding alternative diagnoses explaining patients' symptoms. However, this has not been rigorously examined. METHODS We retrospectively reviewed CTPA done at our center over an eleven year period (2000 - 2010) in patients with suspected pulmonary embolus (PE). We then reviewed in detail the ...

Ponderal somatograms assessed body composition in four groups of Division III collegiate football players: offensive line (OL), defensive line (DL), offensive backs (OB), and defensive backs (DB). Ponderal somatograms evaluate body size and shape by converting muscular (shoulders, chest, biceps, forearm, thigh, and calf) and nonmuscular (abdomen, hips, knee, ankle, and wrist) girths into ponder...

Meditation is associated with positive health behaviors and improved cognitive control. One mechanism for the relationship between meditation and cognitive control is changes in activity of the anterior cingulate cortex-mediated neural pathways. The error-related negativity (ERN) and error positivity (Pe) components of the scalp-recorded event-related potential (ERP) represent cingulate-mediate...

IMPORTANCE Future funding for new treatments in venous thromboembolism will be guided by cost-utility analyses. There is little available information on the utility of acute venous thromboembolism, limiting the validity of economic analyses. OBJECTIVE To measure the quality of life in the health states relating to thromboembolism cost-utility analyses. DESIGN A prospective cohort study. S...

Psychotic disorders are characterized by profoundly blunted neural responses to errors, as indicated by reductions in two event-related potential (ERP) components: the error-related negativity (ERN) and error positivity (Pe). The potential utility of the ERN and Pe as biomarkers for psychotic disorders is currently limited, however, by an incomplete understanding of their psychometric propertie...

Empirical evidence indicates that people can provide accurate evaluations of their own thoughts and actions by means of both error detection and confidence judgments. This study investigates the foundations of these metacognitive abilities, specifically focusing on the relationship between confidence and error judgments in human perceptual decision making. Electroencephalography studies have id...

Relations between a modifiable psychosocial factor, self-efficacy (SE), and behavioral and neural indices of self-regulation, including post-error behavior, the error-related negativity (ERN), and error positivity (Pe) were examined in young adults during a flanker task emphasizing either accuracy or speed. SE was predicted to be associated with larger ERN and Pe amplitudes, as well as greater ...

Rumination is a construct that cuts across a variety of disorders, including anxiety and depression. It has been associated with deficits in cognitive control thought to confer risk for psychopathology. One aspect of cognitive control that is especially relevant to the content of ruminative thoughts is error processing. We examined the relation of rumination and 2 electrophysiological indices o...
