Free radical scavenger posttreatment improves functional and morphological outcome after fluid percussion injury in the rat
Reactive oxygen species (ROS) are thought to contribute to the secondary injury process after traumatic brain injury (TBI). ROS scavenging compounds have shown neuroprotective properties in various models of experimental brain injury, including TBI. Administration of nitrone radical scavengers has emerged as a promising pharmacological concept in focal experimental ischemia due to their low toxici
Effect of traumatic brain injury and nitrone radical scavengers on relative changes in regional cerebral blood flow and glucose uptake in rats
Changes in regional cerebral blood flow (rCBF) and glucose metabolism are commonly associated with traumatic brain injury (TBI). Reactive oxygen species (ROS) have been implicated as key contributors to the secondary injury process after TBI. Here, pretreatment with the nitrone radical scavengers (alpha-phenyl-N-tert-butyl nitrone (PBN) or its sulfonated analogue sodium 2-sulfophenyl-N-tert-butyl
Impact of amoxicillin therapy on resistance selection in patients with community-acquired lower respiratory tract infections : A randomized, placebo-controlled study
Objectives: To determine the effect of amoxicillin treatment on resistance selection in patients with community-acquired lower respiratory tract infections in a randomized, placebo-controlled trial. Methods: Patients were prescribed amoxicillin 1 g, three times daily (n = 52) or placebo (n = 50) for 7 days. Oropharyngeal swabs obtained before, within 48 h post-treatment and at 28-35 days were asse
Administration of monoclonal antibodies neutralizing the inflammatory mediators tumor necrosis factor alpha and interleukin -6 does not attenuate acute behavioral deficits following experimental traumatic brain injury in the rat
PURPOSE: Although many previous studies have indicated that the acute inflammatory response following traumatic brain injury (TBI) is detrimental, inflammation may also positively influence outcome in the more chronic post-injury recovery period. We evaluated the effects of monoclonal antibodies (mAB), neutralizing either IL-6 (IL-6 mAB) or TNF-alpha (TNF mAB), administered intracerebroventricular
Selective temporal and regional alterations of Nogo-A and small proline-rich repeat protein 1A (SPRR1A) but not Nogo-66 receptor (NgR) occur following traumatic brain injury in the rat
Axons show a poor regenerative capacity following traumatic central nervous system (CNS) injury, partly due to the expression of inhibitors of axonal outgrowth, of which Nogo-A is considered the most important. We evaluated the acute expression of Nogo-A, the Nogo-66 receptor (NgR) and the novel small proline-rich repeat protein 1A (SPRR1A, previously undetected in brain), following experimental l
Cognitive outcome following brain injury and treatment with an inhibitor of Nogo-A in association with an attenuated downregulation of hippocampal growth-associated protein-43 expression
OBJECT: Central nervous system axons regenerate poorly after traumatic brain injury (TBI), partly due to inhibitors such as the protein Nogo-A present in myelin. The authors evaluated the efficacy of anti-Nogo-A monoclonal antibody (mAb) 7B12 administration on the neurobehavioral and cognitive outcome of rats following lateral fluid-percussion brain injury, characterized the penetration of the 7B1
Functional outcome is impaired following traumatic brain injury in aging Nogo-A/B-deficient mice
Increasing age is associated with a poor prognosis following traumatic brain injury (TBI). CNS axons may recover poorly following TBI due to expression of myelin-derived inhibitors to axonal outgrowth such as Nogo-A. To study the role of Nogo-A/B in the pathophysiological response of the elderly to TBI, 1-year-old mice deficient in Nogo-A/B (Nogo-A/B homozygous(-/-) mice), Nogo-A/B heterozygous(-/
Effects of the neurological wake-up test on intracranial pressure and cerebral perfusion pressure in brain-injured patients
OBJECTIVE: To evaluate the effects of the neurological "wake-up test" (NWT), defined as interruption of continuous propofol sedation and evaluation of the patient's level of consciousness, on intracranial pressure (ICP) and cerebral perfusion pressure (CPP) in patients with severe subarachnoid hemorrhage (SAH) or traumatic brain injury (TBI).METHODS: A total of 127 NWT procedures in 21 severely br
Genetic deletion and pharmacological inhibition of Nogo-66 receptor impairs cognitive outcome after traumatic brain injury in mice
Functional recovery is markedly restricted following traumatic brain injury (TBI), partly due to myelin-associated inhibitors including Nogo-A, myelin-associated glycoprotein (MAG) and oligodendrocyte myelin glycoprotein (OMgp), that all bind to the Nogo-66 receptor-1 (NgR1). In previous studies, pharmacological neutralization of both Nogo-A and MAG improved outcome following TBI in the rat, and n
Tissue sparing and functional recovery following experimental traumatic brain injury is provided by treatment with an anti-myelin-associated glycoprotein antibody
Axonal injury is a hallmark of traumatic brain injury (TBI) and is associated with a poor clinical outcome. Following central nervous system injury, axons regenerate poorly, in part due to the presence of molecules associated with myelin that inhibit axonal outgrowth, including myelin-associated glycoprotein (MAG). The involvement of MAG in neurobehavioral deficits and tissue loss following experi
The neurological wake-up test does not alter cerebral energy metabolism and oxygenation in patients with severe traumatic brain injury
BACKGROUND: The neurological wake-up test (NWT) is used to monitor the level of consciousness in patients with traumatic brain injury (TBI). However, it requires interruption of sedation and may elicit a stress response. We evaluated the effects of the NWT using cerebral microdialysis (MD), brain tissue oxygenation (PbtiO2), jugular venous oxygen saturation (SjvO2), and/or arterial-venous differen
Improved outcome of patients with severe thalamic hemorrhage treated with cerebrospinal fluid drainage and neurocritical care during 1990-1994 and 2005-2009
INTRODUCTION: Patients with thalamic hemorrhage, depressed level of consciousness and/or signs of elevated intracranial pressure may be treated with neurocritical care (NCC) and external ventricular drainage (EVD) for release of cerebrospinal fluid.METHODS: Forty-three patients with thalamic hemorrhage treated with NCC from 1990 to 1994 (n = 21) and from 2005-2009 (n = 22) were evaluated.

Association between low-density lipoprotein cholesterol-lowering genetic variants and risk of type 2 diabetes : A meta-analysis
IMPORTANCE Low-density lipoprotein cholesterol (LDL-C)-lowering alleles in or near NPC1L1 or HMGCR, encoding the respective molecular targets of ezetimibe and statins, have previously been used as proxies to study the efficacy of these lipid-lowering drugs. Alleles near HMGCR are associated with a higher risk of type 2 diabetes, similar to the increased incidence of new-onset diabetes associated w
The Global Prevalence of Infections in Urology (GPUI) Study : A Worldwide Surveillance Study in Urology Patients
The GPIU study is currently the only study registering health care–associated urogenital tract infections, especially in urology patients, in an ongoing surveillance protocol that can help to deliver data on adequate empirical antibiotic therapy in hospitalised urology patients according to guideline recommendations. The annual GPIU study will continue to be performed in November of each year unde
