Traumatic brain injury (TBI) initiates a deleterious inflammatory response that exacerbates pathology and worsens outcome. This inflammatory response is partially mediated by a reduction in cAMP and a concomitant upregulation of cAMP-hydrolyzing phosphodiesterases (PDEs) acutely after TBI. The PDE4B subfamily, specifically PDE4B2, has been found to regulate cAMP in inflammatory cells, such as neutrophils, macrophages and microglia. To determine if PDE4B regulates inflammation and subsequent pathology after TBI, adult male Sprague Dawley rats received sham surgery or moderate parasagittal fluid-percussion brain injury (2 ± 0...

BACKGROUND: Obesity causes frailty in older adults; however, weight loss might accelerate age-related loss of muscle and bone mass and resultant sarcopenia and osteopenia. METHODS: In this clinical trial involving 160 obese older adults, we evaluated the effectiveness of several exercise modes in reversing frailty and preventing reduction in muscle and bone mass induced by weight loss. Participants were randomly assigned to a weight-management program plus one of three exercise programs - aerobic training, resistance training, or combined aerobic and resistance training - or to a control group (no weight-management or exercise program)...

Hemorrhage continues to be the most common cause of death among service members wounded in combat. Injuries that were previously nonsurvivable in previous wars are now routinely seen by combat surgeons in forward surgical units, the result of improvements in body armor, the universal use of field tourniquets to control extremity hemorrhage at the point of injury, and rapid air evacuation strategies. Combat orthopaedic surgeons remain a vital aspect of the forward surgical unit, tasked with assisting general surgical colleagues in the resuscitation of patients in hemorrhagic shock while also addressing traumatic amputations, open and closed long bone fractures, and mechanically unstable pelvic trauma...

UNLABELLED: Learning and memory impairments are common in traumatic brain injury (TBI) survivors. However, there are no effective treatments to improve TBI-induced learning and memory impairments. TBI results in decreased cAMP signaling and reduced cAMP-response-element binding protein (CREB) activation, a critical pathway involved in learning and memory. TBI also acutely upregulates phosphodiesterase 4B2 (PDE4B2), which terminates cAMP signaling by hydrolyzing cAMP. We hypothesized that a subtype-selective PDE4B inhibitor could reverse the learning deficits induced by TBI...

PURPOSE OF REVIEW: Management of midface trauma is complex and challenging and requires a clear understanding of the facial buttress system, subunit anatomy and inter-relationships. Too often clinicians attempt surgical repair without adequate knowledge of the common complications associated with poor reduction and improper sequencing of fracture repair. This review outlines a working approach to the identification and management of such injuries, and the definitive management of common injury patterns...

Synthetic cannabinoids, which began proliferating in the United States in 2009, have gone through numerous iterations of modification to their chemical structures. More recent generations of compounds have been associated with significant adverse outcomes following use, including cognitive and psychomotor impairment, seizures, psychosis, tissue injury and death. These effects increase the urgency for forensic and public health laboratories to develop methods for the detection and identification of novel substances, and apply these to the determination of their metabolism and disposition in biological samples...

BACKGROUND: Postoperative knee chondrolysis caused by continuous intra-articular pain pumps infusing bupivacaine with epinephrine is a rare but serious complication. PURPOSE: To determine the association between postoperative intra-articular infusion of bupivacaine with epinephrine and the development of knee chondrolysis in patients who have undergone arthroscopic anterior cruciate ligament reconstruction (ACLR). The authors hypothesized that the development of knee chondrolysis after ACLR is associated with postoperative high-dose intra-articular bupivacaine with epinephrine infusion...

This paper presents real world acceleration data for an ambulance driving up and over a curb. A full scale reenactment was performed for a litigated case in which a patient on a gurney in an ambulance claimed a variety of bodily injuries after the ambulance struck a curb. A height and weight matched surrogate rode on the gurney during the tests. Results demonstrated that peak vehicle and occupant accelerations never exceeded 1.1g's. To address the claimed injuries, the accelerations likely sustained by the patient were compared to those experienced during daily life...

Recently, increasing attention has been drawn to haemophagocytic lymphohistiocytosis as a potentially under-diagnosed condition in critically ill patients with severe sepsis. It is thought to be caused by a highly stimulated, but ineffective, immune system. We report the case of a patient suffering from major burns who, despite extensive investigations showing the absence of concurrent sepsis or infection, developed haemophagocytic lymphohistiocytosis refractory to treatment. We believe that this is the first report suggestive of haemophagocytic lymphohistiocytosis triggered by a burns injury...

Adiponectin (Ad), an adipokine exclusively secreted by the adipose tissue, has emerged as a paracrine metabolic regulator as well as a protectant against oxidative stress. Pharmacological approaches of protecting against clinical hyperoxic lung injury during oxygen therapy/treatment are limited. We have previously reported that Ad inhibits the NADPH oxidase-catalyzed formation of superoxide from molecular oxygen in human neutrophils. Based on this premise, we conducted studies to determine whether (i) exogenous Ad would protect against the hyperoxia-induced barrier dysfunction in the lung endothelial cells (ECs) in vitro, and (ii) endogenously synthesized Ad would protect against hyperoxic lung injury in wild-type (WT) and Ad-overexpressing transgenic (AdTg) mice in vivo...

Acute kidney injury (AKI) is a frequent complication after cardiopulmonary bypass surgery during infancy. Standard methods for evaluating renal function are not particularly sensitive nor are proximate indicators of renal dysfunction that allow intervention in real time. Near-infrared spectroscopy (NIRS) is a newer noninvasive technology that continuously evaluates regional oximetry and may correlate with renal injury and adverse outcomes after cardiac surgery in infants. This prospective observational study enrolled 40 infants (age, <12 months) undergoing biventricular repair...

A 50-year-old man was the victim of an accidental arrow shooting while hunting. The arrow entered his posterolateral neck and came to rest in the space between the C1/C2 vertebrae in his cervical spine. He was able to maintain his own cervical immobilization. His hunting partners drove him to meet emergency medical technicians, who stabilized the arrow shaft, transferred him to a backboard and gurney, and continued manual cervical immobilization en route to a local hospital. Cervical spine X-ray results compelled an air ambulance transfer to a trauma center where he underwent surgical intervention to remove the arrow...
