Preparing clinicians for practice: effectiveness and design of on-call simulation.

Background: Final year medical students and postgraduate doctors regularly contend with feelings of under-preparedness when transitioning into new areas of clinical practice. This lack of confidence is most evident in the context of on-call work which frequently requires sound clinical prioritisation, rigorous decision making and the management of acutely unwell patients, often with reduced senior support and staffing. This has prompted the emergence of on-call simulation which seeks to enhance participant confidence in performing on-call tasks and facilitate the development of key clinical and non-technical skills.

Considerable variation in current coronoid height and fracture measurement techniques: a systematic review.

Background: Coronoid fractures usually occur in the presence of a significant osseoligamentous injury to the elbow. Fracture size and location correlate with degree of instability and many authors have attempted to analyze the effect of fracture variation on decision making and outcome. There remains no standardized technique for measuring coronoid height or fracture size.

Return of large fin whale feeding aggregations to historical whaling grounds in the Southern Ocean.

Fin whales (Balaenoptera physalus quoyi) of the Southern Hemisphere were brought to near extinction by twentieth century industrial whaling. For decades, they had all but disappeared from previously highly frequented feeding grounds in Antarctic waters. Our dedicated surveys now confirm their return to ancestral feeding grounds, gathering at the Antarctic Peninsula in large aggregations to feed.

Copy number gain of 11q13.3 genes associates with pathological stage in hypopharyngeal squamous cell carcinoma.

Squamous cell carcinomas of the hypopharynx (HPSCC) and oropharynx (OPSCC) have markedly different patient outcomes. Differences in HPV prevalence between these two patient groups may account for some of this difference, but other molecular markers of prognosis or pathological phenotype have not been established. Copy number gain of oncogenes is a well-established molecular change contributing to HNSCC development.

Public Health Amendment (Vaccination of Children Attending Child Care Facilities) Act 2013: its impact in the Northern Rivers, NSW.

Objective: The objective of the study was to explore the impact of implementation of the Public Health Amendment (Vaccination of Children Attending Child Care Facilities) Act 2013 on child-care centres in the Northern Rivers region of New South Wales (NSW), from the perspective of child-care centre directors. Importance of study: Immunisation is an effective public health intervention, but more than 75 000 Australian children are not fully vaccinated. A recent amendment to the NSW Public Health Act 2010 asks child-care facilities to collect evidence of complete vaccination or approved exemption before allowing enrolment.

Formalin fixed paraffin embedded (FFPE) material is amenable to HPV detection by the Xpert(®) HPV assay.

Background: The Xpert(®) HPV Assay (Cepheid(®), Sunnyvale, USA) is a rapid, cartridge-based HPV test validated for use on cervical cytology samples. However, there is an increasing demand for HPV annotation of formalin fixed paraffin embedded (FFPE) material.

Objectives: The aim of this study was to determine the suitability of the Xpert HPV assay for the detection of nucleic acid (NA) derived from FFPE samples.

A quality improvement evaluation case study: impact on public health outcomes and agency culture.

Background: Quality improvement (QI) is increasingly recognized as an important strategy to improve healthcare services and health outcomes, including reducing health disparities. However, there is a paucity of evidence documenting the value of QI to public health agencies and services.

Purpose: The purpose of this project was to support and assess the impact on the outcomes and organizational culture of a QI project to increase immunization rates among children aged 2 years (4:3:1:3:3:1 series) within a large public health agency with a major pediatric health mission.

Effect of severe hurricanes on biorock coral reef restoration projects in Grand Turk, Turks and Caicos Islands.

Artificial reefs are often discouraged in shallow waters over concerns of storm damage to structures and surrounding habitat. Biorock coral reef restoration projects were initiated in waters around 5 m deep in Grand Turk, at Oasis (October 2006) and at Governor's Beach (November 2007). Hemi-cylindrical steel modules, 6m long were used, four modules at Oasis and six at Governor's Beach.
