Travel nurse work experiences: A comparison of staff and travel nurses' burnout and job attitudes.

A survey of 330 hospital RNs assessed burnout, job satisfaction, turnover intentions, and perceptions of work assignments. Understanding how travel nurses' work experiences differ from the experiences of staff nurses can help nurse leaders determine the best approaches to manage and support these nurses.

Starting fresh: a mixed method study of follower job satisfaction, trust, and views of their leader's behavior.

Introduction: The leadership literature has been dominated by the study of broad styles rather than the identification of specific key behaviors. To address this deficiency, a mixed method approach was utilized to explore how follower behavioral descriptions of their leaders would relate to potential outcomes of trust in that leader and job satisfaction.

Methods: Data were collected from 273 hospital direct reports of 44 managers.

Organizational science and cybersecurity: abundant opportunities for research at the interface.

Cybersecurity is an ever-present problem for organizations, but organizational science has barely begun to enter the arena of cybersecurity research. As a result, the "human factor" in cybersecurity research is much less studied than its technological counterpart. The current manuscript serves as an introduction and invitation to cybersecurity research by organizational scientists.

Metabolic basis to Sherpa altitude adaptation.

The Himalayan Sherpas, a human population of Tibetan descent, are highly adapted to life in the hypobaric hypoxia of high altitude. Mechanisms involving enhanced tissue oxygen delivery in comparison to Lowlander populations have been postulated to play a role in such adaptation. Whether differences in tissue oxygen utilization (i.

Tablet Computing in Clinical Training of Pediatric Residents.

Background: Medical residents receive both medical education and clinical skills training. New technologies and pedagogies are being developed to address each of these phases. Our research focuses on the efficacy of an iPad(®) (Apple, Cupertino, CA) for clinical skills training.

Fenofibrate administration does not affect muscle triglyceride concentration or insulin sensitivity in humans.

Animal data suggest that males, in particular, rely on peroxisome proliferator activated receptor-α activity to maintain normal muscle triglyceride metabolism. We sought to examine whether this was also true in men vs women and its relationship to insulin sensitivity (Si). Normolipidemic obese men (n = 9) and women (n = 9) underwent an assessment of Si (intravenous glucose tolerance test) and intramuscular triglyceride (IMTG) metabolism (gas chromatography/mass spectrometry and gas chromatography-combustion isotope ratio mass spectrometry from plasma and muscle biopsies taken after infusion of [U-(13)C]palmitate) before and after 12 weeks of fenofibrate treatment.

Occult squamous cell carcinoma of the uvula detected by F-18 FDG PET/CT in a case of carcinoma of unknown primary in the head and neck.

Incidence of unknown primary head/neck tumors with metastatic cervical lymphadenopathy at time of diagnosis is approximately 2% to 9%. Detecting site of original disease is challenging. We present a 75-year-old woman with bulky unilateral level 2 and 3 lymphadenopathy.

Should we treat lung metastases from adenoid cystic carcinoma of the head and neck in asymptomatic patients?

Adenoid cystic carcinoma is a rare malignant tumor that is well known for its deceptively encouraging 5-year survival rate and its dismal survival rate at longer intervals. Controversy exists as to the benefit of regularly following asymptomatic patients to look for distant metastases because even if one is found, the options for further management are limited. When a metastasis is limited to the lung in an asymptomatic patient with no locoregional recurrence, metastasectomy might provide some long-term benefit, although we cannot know for certain.

Penicillium species as a rare isolate in tracheal granulation tissue: a case series.

Introduction: Granulation tissue formation is a major problem complicating the treatment of upper airway stenosis. We present two cases of recurrent tracheal granulation tissue colonisation by Penicillium species in patients undergoing laryngotracheal reconstructive surgery for post-intubation tracheal stenosis. We believe that although most Penicillium species do not cause invasive disease they can be a contributory factor to the occurrence of upper airway stenosis.

Outcome of endoscopic treatment of adult postintubation tracheal stenosis.

Objectives/hypothesis: To assess the results of primary endoscopic treatment of adult postintubation tracheal stenosis, to identify predictors of a successful outcome, and better define the scope and limitations of minimally-invasive surgery for this condition.

Methods: Sixty-two consecutive patients treated between April 2003 and 2006 with initial endoscopic surgery were prospectively studied. Patient and lesion characteristics, treatment details, complications, decannulation, and open surgery rates were recorded.

Quantifying the physiology of laryngotracheal stenosis: changes in pulmonary dynamics in response to graded extrathoracic resistive loading.

Objectives/hypothesis: A model of airway obstruction was developed to study the impact of changes in airway resistance on ventilatory mechanics. This was used to derive quantitative indices of airway obstruction to aid in the objective diagnosis and physiological monitoring of adult patients with laryngotracheal stenosis (LTS).

Methods: Six airway resistors, the characteristics of which mirrored the selective impediment to inspiratory airflow that occurs in patients with LTS, were created and calibrated.

Endoscopic resection of malignant tumors of the nose and sinuses.

Background: Since the introduction of endoscopic surgery, its role has been gradually extended to encompass a range of pathologies, including sinonasal tumors, facilitated by the ability to repair significant skull-base defects. However, the rarity and long natural history of malignant tumors make it difficult to accrue cohorts comparable with the established gold standard of craniofacial resection.

Methods: In this prospective cohort study, after histological confirmation and a staging imaging protocol, patients deemed suitable were offered the option of an entirely endoscopic resection as an alternative to craniofacial resection.

The role of mitomycin C in surgery of the frontonasal recess: a prospective open pilot study.

Background: Mitomycin C (MMC) inhibits fibroblast proliferation. The objective of this study was to determine the efficacy of MMC in reducing frontal ostium stenosis after endoscopic sinus surgery.

Methods: A prospective open pilot study was conducted in 28 patients who had undergone one or more previous surgical interventions for frontal sinusitis.

Bacterial colonization of airway stents: a promoter of granulation tissue formation following laryngotracheal reconstruction.

Objective: To investigate whether airway granulation, a common occurrence during laryngotracheal reconstructive surgery and a common cause of delays in definitive treatment and treatment failure, is associated with a microbial etiology.

Design: Prospective case-control study.

Setting: Tertiary referral airway reconstruction unit.

Early endoscopic treatment of acute inflammatory airway lesions improves the outcome of postintubation airway stenosis.

Objectives/hypothesis: The objective of this study was to compare the results of treating acute postintubation stenotic airway lesions with the results of treating mature lesions and to assess whether early intervention improves the outcome.

Methods: Patients without previous surgery, treated for postintubation airway stenosis, were reviewed. Those with airway lesions presenting within weeks of intubation (n = 11) were treated with intralesional steroids, laser reduction, and balloon dilatation.

Craniofacial resection for tumors of the nasal cavity and paranasal sinuses: a 25-year experience.

Background: Craniofacial resection is the established "gold standard" for surgical treatment of tumors affecting the anterior skull base.

Methods: This study analyzed 308 patients (220 males, 88 females) who had undergone craniofacial resection for sinonasal neoplasia with up to 25-year follow-up.

Results: An overall actuarial survival of 65% at 5 years and 47% at 10 years was found for the cohort as a whole.

The effect of treatment for epistaxis secondary to hereditary hemorrhagic telangiectasia.

Background: Epistaxis is the most common symptom in patients with hereditary hemorrhagic telangiectasia. Different treatment options have been described but with little reference to their effect on quality of life or disease severity.

Methods: This study prospectively investigated the effect of nasal closure, argon laser, and a combination of septodermoplasty and argon laser treatments on quality-of-life scores and disease severity ratings in a group of 29 patients with moderate to severe epistaxis referred to a tertiary referral center.

The SF-36 health status questionnaire in assessing patients with epistaxis secondary to hereditary hemorrhagic telangiectasia.

Background: This study assesses the ability of the short form 36 (SF-36), a validated health status survey, to measure the health of patients with epistaxis due to hereditary hemorrhagic telangiectasia (HHT).

Methods: Thirty-eight patients completed the SF-36 and symptom-specific questionnaires. They were asked to rate their epistaxis as severe, moderate, or mild.

Database for the collection and analysis of clinical data and images of neoplasms of the sinonasal tract.
