Surgical patients frequently experience postoperative increases in creatinine levels. The authors hypothesized that even small increases in postoperative creatinine levels are associated with adverse outcomes. ⋯ Even minor postoperative increases in creatinine levels are associated with adverse outcomes. These results emphasize the importance to find effective therapeutic approaches to prevent or treat even mild forms of postoperative kidney dysfunction to improve surgical outcomes.

ReviewMoving Beyond Metabolic Encephalopathy: An Update on Delirium Prevention, Workup, and Management.
Delirium is a condition that frequently complicates hospitalization and consists of an acute decline in orientation and attention, often accompanied by other cognitive changes. Delirium is tied to multiple detrimental outcomes both in the short and long term, including cognitive and functional decline, inpatient complications, and mortality. ⋯ In general, instituting a system of active screening of at-risk populations and nonpharmacologic interventions for prevention and treatment seems to be the most effective method of addressing delirium. More research is needed to clarify the etiology of delirium and develop safe therapeutic options that address the underlying pathophysiology.

ReviewThrombotic thrombocytopenic purpura: from diagnosis to therapy.
Thrombotic thrombocytopenic purpura (TTP) is a rare but challenging disease for intensive care specialists. Patients with acute TTP frequently require admission to the intensive care unit because of organ dysfunctions due to the disease or because of the risk of sudden aggravation at the onset of the disease. This review aims at describing recent evolutions in the diagnosis and for the management of TTP for the use of intensive care specialists. ⋯ The classification of thrombotic microangiopathies has evolved from a clinical to a pathophysiological definition. TTP is characterized by a severe ADAMTS13 deficiency that can be documented in vitro, along with anti-ADAMTS13 antibodies in most adult cases. Plasmapheresis and immunosuppressive therapy with steroids remain the standard of care for acute inaugural TTP. Anti-CD20 monoclonal antibody rituximab is safe and indicated in relapsing and/or refractory TTP. Its indication in inaugural TTP remains to be evaluated but is nevertheless recommended by experts. Novel therapies for TTP are still in preclinical phases.

ReviewChronic Histopathological and Behavioral Outcomes of Experimental Traumatic Brain Injury in Adult Male Animals.
The purpose of this review is to survey the use of experimental animal models for studying the chronic histopathological and behavioral consequences of traumatic brain injury (TBI). The strategies employed to study the long-term consequences of TBI are described, along with a summary of the evidence available to date from common experimental TBI models: fluid percussion injury; controlled cortical impact; blast TBI; and closed-head injury. For each model, evidence is organized according to outcome. ⋯ The majority of experimental TBI studies collect data in the acute postinjury period, but few continue into the chronic period. Available evidence from long-term studies suggests that many of the experimental TBI models can lead to progressive changes in histopathology and behavior. The studies described in this review contribute to our understanding of chronic TBI pathology.

The number of patients with noncardiac implantable electronic devices is increasing, and the absence of perioperative management standards, guidelines, practice parameters, or expert consensus statements presents clinical challenges. A 69-year-old woman presented for latissimus dorsi breast reconstruction. The patient had previously undergone implantation of a spinal cord stimulator, a gastric pacemaker, a sacral nerve stimulator, and an intrathecal morphine pump. ⋯ Bipolar cautery was used intraoperatively. Postoperatively, all devices were interrogated to ensure appropriate functioning before home discharge. Perioperative goals include complete preoperative radiologic documentation of device component location, minimizing electromagnetic interference, and avoiding mechanical damage to implanted device components.
