Associating frailty and dynamic dysregulation between motor and cardiac autonomic systems.

Frailty is a geriatric syndrome associated with the lack of physiological reserve and consequent adverse outcomes (therapy complications and death) in older adults. Recent research has shown associations between heart rate (HR) dynamics (HR changes during physical activity) with frailty. The goal of the present study was to determine the effect of frailty on the interconnection between motor and cardiac systems during a localized upper-extremity function (UEF) test.

Preservation of the inferior alveolar vasculonervous bundle in mandibular resective therapies: systematic review and report of two cases.

Background: Segmental surgical resection is a frequently indicated procedure to treat aggressive mandibular tumors. One of the most important complications derived from this technique is permanent paresthesia of the inferior alveolar nerve (IAN), which significantly affects the quality of life of patients who experience it. This could be avoided through maneuvers that preserve the IAN.

Low-Rank Representation of Head Impact Kinematics: A Data-Driven Emulator.

Head motion induced by impacts has been deemed as one of the most important measures in brain injury prediction, given that the vast majority of brain injury metrics use head kinematics as input. Recently, researchers have focused on using fast approaches, such as machine learning, to approximate brain deformation in real time for early brain injury diagnosis. However, training such models requires large number of kinematic measurements, and therefore data augmentation is required given the limited on-field measured data available.

Symptomatic macroglossia and tongue myositis in polymyositis: treatment with corticosteroids and intravenous immunoglobulin.

Symptomatic macroglossia occurs in some rare congenital muscle diseases, such as Becker's and Duchenne's dystrophies or Pompe's disease. Herein we describe a case of symptomatic macroglossia with myositis of the tongue occurring in a patient with polymyositis. Tongue myositis was evidenced by dysarthria, frequent biting during mastication, swallowing difficulties without aspiration, and noisy breathing.
