Severe secretion retention: a predictor of decannulation outcome in severe brain injury patients with tracheostomy.

Background: Identifying accurate predictors of decannulation outcome is essential to ensure safe and timesaving decannulation. Studies indicated hypopharyngeal secretion retention is closely associated with compromised airway protection and patients with it are less likely to be decannulated. However, data verifying the link between secretion retention and decannulation outcome are lacking.

More is less: Effect of ICF-based early progressive mobilization on severe aneurysmal subarachnoid hemorrhage in the NICU.

Introduction: Aneurysmal subarachnoid hemorrhage (aSAH) is a type of stroke that occurs due to a ruptured intracranial aneurysm. Although advanced therapies have been applied to treat aSAH, patients still suffer from functional impairment leading to prolonged stays in the NICU. The effect of early progressive mobilization as an intervention implemented in the ICU setting for critically ill patients remains unclear.

Methods: A name that was most familiar to the subject (SFN) was added as a self-related reference. We used 4 auditory stimuli-pure tone (1000 Hz), SON, SDN, and SFN-to evaluate the corresponding activated brain areas in 19 healthy subjects by using functional magnetic resonance imaging.

Autogenous bone particles combined with platelet-rich plasma can stimulate bone regeneration in rabbits.

Long-term bone defects are a key clinical problem. Autogenous bone graft remains the gold standard for the treatment of these defects; however, improving the osteogenic properties and reducing the amount of autogenous bone is challenging. Autologous platelet-rich plasma (PRP) has been widely considered for treatment, due to its potentially beneficial effect on bone regeneration and vascularization.

Multidimensional review of cognitive impairment after spinal cord injury.

Cognitive impairment is highly prevalent in the population with spinal cord injury (SCI) and exerts a significant impact on functional independence and quality of life in this population. A number of neuroscientists have conducted preliminary investigations of cognitive deficits after SCI, but achieved marginally contradictory results due to some limitations such as the heterogeneity in the sample population, sample size, types of tests utilized, study design, and time since SCI. Therefore, this review mainly focuses on the characteristics, assessments, potential causality and treatment of cognitive impairment for better understanding such deficits in the SCI population.
