Retrospective Analysis of Risk Factors in Geriatric Hip Fracture Patients Predictive of Surgical Intensive Care Unit Admission.

Introduction: Although numerous risk factors and prediction models affecting morbidity and mortality in geriatric hip fracture patients have been previously identified, there are scant published data on predictors for perioperative Surgical Intensive Care Unit (SICU) admission in this patient population. Determining if a patient will need an SICU admission would not only allow for the appropriate allocation of resources and personnel but also permit targeted clinical management of these patients with the goal of improving morbidity and mortality outcomes. The purpose of this study was to identify specific risk factors predictive of SICU admission in a population of geriatric hip fracture patients.

Resource Deployment in Response to Trauma Patients.

Background Variance in the deployment of the trauma team to the emergency department (ED) can result in patient treatment delays and excess burden on ED personnel. Characteristics of trauma patients, including mechanism of injury, injury type, and age, have been associated with differences in trauma resource deployment. Therefore, this retrospective, single-site study aimed to examine the deployment patterns of trauma resources, the characteristics of the trauma patients associated with levels of trauma resource deployment, and the deployment impact on ED workforce utilization and non-trauma ED patients.

Predicting Instability Risk Following Hemiarthroplasty for Femoral Neck Hip Fractures in Geriatric Patients.

Background: Although a rare complication, dislocation following hemiarthroplasty (HA) for a femoral neck hip fracture is associated with increased mortality, readmission, and possible revision surgery. To date many of the specific risk factors have been difficult to demonstrate. Patient factors, surgical factors, as well as morphological factors need to be assessed.

Lateral femoral cutaneous nerve palsy following shoulder surgery in the beach chair position: a report of 4 cases.

Neuropathy of the lateral femoral cutaneous nerve can present as pain, decreased sensation, and/or burning or tingling on the anterolateral thigh. We present 4 cases of lateral femoral cutaneous nerve palsy following shoulder surgery in the beach chair position, all of which occurred in obese patients. This complication, to our knowledge, has never been reported in conjunction with the beach chair position.

A sustainable training strategy for improving health care following a catastrophic radiological or nuclear incident.

The detonation of a nuclear device in a US city would be catastrophic. Enormous loss of life and injuries would characterize an incident with profound human, political, social, and economic implications. Nevertheless, most responders have not received sufficient training about ionizing radiation, principles of radiation safety, or managing, diagnosing, and treating radiation-related injuries and illnesses.

Contrasting roles of protein kinase C in induction versus suppression of group I mGluR-mediated epileptogenesis in vitro.

Activation of group I metabotropic glutamate receptors (mGluRs) elicits persistent ictaform discharges in guinea pig hippocampal slices, providing an in vitro model of epileptogenesis. The induction of these persistent ictaform bursts is prevented by l-cysteine sulfinic acid (CSA), an agonist at phospholipase D (PLD)-coupled mGluRs. Studies described herein examined the role of protein kinase C (PKC) in both the group I mGluR-mediated induction and CSA-mediated suppression of this form of epileptogenesis.
