Nurse Preceptor Burnout: Contributing Factors.

Objective: The aim of this study was to assess nurse preceptor burnout and examine related factors.

Background: Nurse preceptors are essential to the provision of optimal hospital-based care. Preceptors guide and support nurses' transition from professional training to practice as well as movement within practice roles.

Trenches reduce crop foraging by elephants: Lessons from Kibale National Park, Uganda for elephant conservation in densely settled rural landscapes.

Crop loss to wildlife, particularly elephants, threatens livelihoods and support for conservation around many protected areas in Africa and Asia. Low-cost elephant barriers have been successfully deployed in savannas but seldom tested around isolated forest parks where the stakes are high for local farmers and isolated elephant populations. We measured the effectiveness of a series of ≥3 m deep trenches dug by farmers neighboring Kibale National Park, Uganda.

Diagnostic Dilemma in a Case of Necrotizing Pneumonia With Negative Transbronchial Biopsy.

A 33-year-old male with a past medical history of asthma presented to the Emergency room with a three-day history of right-sided chest pain, productive cough with dark brown sputum, and shortness of breath. He was found to have right lower lobe consolidation consistent with acute pneumonia, and areas of non-homogenous density within the consolidation, suspicious of necrotizing pneumonia. Computed tomography (CT) of the chest with IV contrast revealed a large, irregular thick-walled cavitary mass involving the right middle lobe with surrounding ground glass cavitation.

Preparing New Graduate Nurses for Patient Rescue: An Experimental Quantitative Study.

A patient deterioration educational program was offered to new graduate nurses. Pre and post self-confidence scores were compared, and competency performance was evaluated during a simulation. The results indicate that most of the participants successfully demonstrated simulation competencies, and there was a statistically significant improvement in self-confidence scores.

The Baptist Health Lexington Nursing Orientation Progression Tool: A Methodological Study.

Objective: The purpose of this study was to develop and test a tool to monitor a nursing orientee's progress to competence.

Background: The literature suggests that, during orientation, consistent documentation and communication among educators, preceptors, and nurse leaders facilitate a timely progression to independent practice for new nurses.

Methods: A 2-phase methodological study was conducted.

PBX transcription factors drive pulmonary vascular adaptation to birth.

A critical event in the adaptation to extrauterine life is relaxation of the pulmonary vasculature at birth, allowing for a rapid increase in pulmonary blood flow that is essential for efficient gas exchange. Failure of this transition leads to pulmonary hypertension (PH), a major cause of newborn mortality associated with preterm birth, infection, hypoxia, and malformations including congenital diaphragmatic hernia (CDH). While individual vasoconstrictor and dilator genes have been identified, the coordination of their expression is not well understood.

II. Evaluation of the impact of alternative light technology on male broiler chicken stress.

This study evaluates the impact of light-emitting diodes (LEDs), cold cathode fluorescent lamps (CCFLs), and incandescent lamps on broiler welfare in response to recent interest in the agriculture industry to transition to more energy-efficient lighting technologies. Male Ross 708 broilers (n=672) were raised to 6 wk age in 8 light-tight modified large colony houses under identical intermittent lighting conditions using 4 unique types of lamps, which were gradually dimmed throughout the study. Incandescent lamps served as the control; experimental technologies tested were a CCFL, and 2 different LED lamps.

I. Evaluation of the impact of alternative light technology on male broiler chicken growth, feed conversion, and allometric characteristics.

This study evaluates the impact of light-emitting diode (LED), cold cathode fluorescent (CCFL), and incandescent lamps on broiler performance. Male Ross 708 broilers (n=672) were raised to 6 wk age in 8 black-out modified large colony houses, under identical intermittent lighting conditions using 4 unique types of lamps, which were gradually dimmed throughout the study. Incandescent lamps served as the control; experimental technologies tested included CCFL and 2 different LED lamps.

A unique cutaneous presentation of Burkitt lymphoma.

Few reports of cutaneous Burkitt lymphoma exist in the literature. Here, the authors describe the case of a human immunodeficiency virus-positive individual with the rare diagnosis of cutaneous Burkitt lymphoma. Three weeks before the development of his cutaneous lesions, the patient experienced bilateral lower extremity paralysis, and an epidural mass was found.

Understanding the risk factors for violence and criminality in women: the concurrent validity of the PCL-R and HCR-20.

This study explores the performance of 132 female maximum-security inmates on the Psychopathy Checklist-Revised (PCL-R) and the HCR-20 (Historical, Clinical, and Risk Management Scheme) to examine the concordance between these two risk assessment instruments, and to assess their potential usefulness in determining level of risk for violent behavior and other forms of criminality. The two instruments demonstrated consistent and highly significant correlations across total scores, factor scores, and subscale scores. When the two instruments were entered into a multiple regression analysis to predict violent and non-violent crime, the HCR-20 did not add to the variance explained by the PCL-R.
