Randomized Controlled Trial Observational Study
'Stop sign' position for subclavian ultrasound: a single-blinded observational study of subclavian vein dimensions.
Right subclavian vein (SCV) dimensions were evaluated on ultrasound and whether these change when the right upper limb is in a neutral position compared with the 'stop sign' position (shoulder abducted and externally rotated to 90°, elbow flexed to 90°), and when patients were positioned 30° head-up compared with lying supine. ⋯ Utilizing the stop sign position does not change SVC dimensions when patients are supine, however, may improve dimensions when lying supine is contraindicated.

The association between objective nutritional indexes and prognosis in patients with acute heart failure have not been well studied. Therefore, we aimed to compare the prognostic value of modified Glasgow prognostic score, prognostic nutritional index, controlling nutritional status score, and geriatric nutritional risk index for the prediction of in-hospital mortality in patients with acute heart failure. ⋯ Though all objective nutritional indexes were associated with prognosis in elderly patients with acute heart failure, geriatric nutritional risk index was superior to other scores in predicting in-hospital mortality.
