Background D-dimers are used in conjunction with clinical probability scores in the assessment of venous thromboembolism (VTE), and they are elevated in other conditions, including malignancy, infection and arrhythmias. High levels of D-dimers in VTE are associated with adverse outcomes, including increased mortality. Their significance in patients without VTE has not previously been established. ...

The impact of small anions on the physical properties of gel-forming mucin has been almost overlooked relative to that of cations. Recently, based on the coincident abnormalities in HCO(3)(-) secretion and abnormal mucus formed in the hereditary disease, Cystic Fibrosis (CF), HCO(3)(-) was hypothesized to be critical in the formation of normal mucus by virtue of its ability to sequester Ca(2+) fro...

About half of the patients suffering from heart failure present with sleep-disordered breathing. In most cases obstructive and central breathing disturbances (including Cheyne-Stokes respiration [CSR]) coexist. CSR is defined by a waxing and waning pattern of the tidal volume. While its pathophysiology has not been elucidated completely, increased ventilatory sensitivity for CO2 and therefore an i...

Memory impairment is common following traumatic brain injury (TBI), but interventions to improve memory in persons with TBI have been ineffective. Retrieval practice is a robust memory strategy among healthy undergraduates, whereby practice retrieving information shortly after it is presented leads to better delayed recall than simple restudy. In a verbal paired associate paradigm, we investigated...

Dysplasia affecting the oral mucosa has a malignant potential. The options for treatment of oral dysplasia are limited. Surgery remains the mainstay of management, with no strong evidence for medical treatments currently available. Histological grading alone does not accurately predict which dysplastic lesions will progress to cancer, which poses the clinician with difficult decisions regarding th...

Breakage of a PICC Line. :: Added: Unknown

Traumatic brain injury (TBI) results in a variable degree of cerebral atrophy that is not always related to cognitive measures across studies. However, the use of different methods for examining atrophy may be a reason why differences exist. The purpose of this manuscript was to examine the predictive utility of seven magnetic resonance imaging (MRI) -derived brain volume or indices of atrophy for...
