RESUMEN
This evidence-based case study follows a child from a nursing assessment on the day of his elective surgery at a children's hospital for myringotomy and insertion of grommets under general anaesthesia through to his arrival at the operating room. Potential pre-operative problems are identified and two problems that arose are discussed in detail. The main care provider in this case was a student nurse referred to as 'the nurse', supported by a qualified nurse, referred to as the 'registered nurse', who performed some assessments.

OBJECTIVE: This paper reports on the experiences and perspectives of community members in relation to advance healthcare directives and enduring power of attorney, including the factors that encourage or discourage engagement in advance care planning (ACP). METHODS; A qualitative methodology was used involving 26 in-depth telephone interviews with community members (mean age 66 years). The aims of the interview question were to gain an understanding of: (1) motivations for engaging in ACP; (2) barriers that prevent people from engaging in ACP; and (3) suggestions for promoting ACP. RESULTS: The findings suggest that: (1) community members lack knowledge about ACP; (2) forms appear inaccessible and complex; (3) community members avoid ACP due to fear, mistrust and concerns over control; and (4) there are misperceptions regarding the relevance of ACP based on age and health. CONCLUSIONS: There is unnecessary fear, avoidance and mistrust around ACP activities, largely resulting from misinformation. There is an undoubted need for greater education and support to be offered to individuals and their families regarding ACP, its benefits and its limitations.

This article presents findings from six focus groups with health care practitioners in an Australian hospital during 2010, which sought to elicit their perspectives on the barriers for people to plan their future health care should they become unwell. Such knowledge is invaluable in overcoming the barriers associated with advance care planning and enhancing the uptake of advance directives and the appointment of an enduring power of attorney for people of all ages. A person's rights to self-determination in health care, including decision making about their wishes for future care in the event they lose cognitive capacity, should not be overlooked against the backdrop of increasing pressure on health care systems. Findings suggest that multiple barriers exist, from practitioners' perspectives, which can be divided into three major categories, namely: patient-centred, practitioner-centred and system-centred barriers. Specifically, patient-centred barriers include lack of knowledge, accessibility concerns, the small 'window of opportunity' to discuss advance care planning, emotional reactions and avoidance when considering one's mortality, and demographic influences. At the practitioner level, barriers relate to a lack of knowledge and uncertainty around advance care planning processes. Systemically, legislative barriers (including a lack of a central registry and conflicting state legislation), procedural issues (particularly in relation to assessing cognitive capacity and making decisions ad hoc) and questions about delegation, roles and responsibilities further compound the barriers to advance care planning.

Social work clinicians across health care settings are uniquely positioned to disseminate valuable practice experience, thereby contributing to knowledge development within their field of practice and across disciplines. Unfortunately, practitioners tend to shy away from writing and research, and are often reluctant to publicly disseminate their expertise through peer-reviewed journals and conference presentations. To better support health social workers in scholarly endeavors, we developed and implemented The Writing Series Project in southeast Queensland, Australia. This article reports on the development, programmatic challenges and practitioner feedback that offer insight into the benefits and pitfalls that we encountered.

BACKGROUND: Kangaroo care (KC), or skin-to-skin care, occurs when an infant is dressed in a diaper and held to a parent's bare chest. This form of holding has been shown to have many benefits for hospitalized infants and has been shown to be a safe and feasible intervention to support infants with congenital heart disease. Despite known benefits, KC was not implemented routinely and consistently in our cardiac center for infants with congenital heart disease. The purpose of this project was to support use of KC as a nursing intervention for hospitalized infants with congenital heart disease and their parents. METHODS: A KC quality improvement committee formed to develop strategies to increase frequency of KC, including the creation of a new nursing policy and procedure on KC for infants, adaptation of the electronic health record to facilitate KC documentation, education, and supporting translation of KC into practice through the cardiac center's first Kangaroo-A-Thon. RESULTS: Twenty-six nurses initiated KC 43 times with 14 patients over the 8-week period for the Kangaroo-A-Thon. No adverse events were reported as a result of infants being held by their parents in KC. CONCLUSION: Our local initiative provided preliminary evidence that KC can be safely integrated into standard care for hospitalized infants with congenital heart disease. Formal standards and procedures, along with creative initiatives such as a Kangaroo-A-Thon, can be a first step toward fostering the translation of KC into practice.

Substantial epidemiological evidence supports the association between alcohol consumption and the risk of breast cancer; however, information on alcohol consumption is not routinely collected by breast screening services in NSW. This study was conducted to investigate the level of self-reported alcohol use among women accessing North Coast Breast Screen in Lismore, NSW. Two hundred and sixty-four consecutive women were screened using the Alcohol Use Disorders Identification Test. Their drinking status was categorised as low risk, risky or high risk. Two-thirds of the screened women (69.7%) were classified as low-risk drinkers; 9.8% as risky and 0.4% as high-risk drinkers. Although the risk of breast cancer increases with the amount of alcohol consumed, evidence suggests that even low-risk drinking is associated with increased risk of breast cancer. Implications for prevention activities by breast screening services are discussed.

The most common alcohol-related chronic condition for hospitalisation is alcohol dependence which can lead to an alcohol withdrawal syndrome (AWS). The aim of this paper is to report on a quality improvement program in an Australian rural area health service for the screening and management of alcohol withdrawal and the effect of two types of nursing education and training approaches: a self-directed competency training package and a more traditional in-service program. The measure of improvement was compliance to nine clinical standards or core competencies for the assessment and treatment of the AWS derived from the Clinical Institute Withdrawal Assessment for Alcohol-Revised (CIWA-Ar) scale and the NSW drug and alcohol withdrawal clinical practice guidelines. An audit of medical records using a standardised protocol for the nine standards was conducted at baseline (n=100) and follow-up (n=340) across eleven hospitals in the area. Results indicated that in three hospitals, where 70 nurses completed the self-directed competency training, there was a higher total compliance score across the nine standards compared to eight hospitals where 238 nurses received the in-service program. The self-directed competency program was also rated highly by nurses who participated in the program. The benefits of self-directed competency training are discussed as well as future recommendations for improving nurse education strategies for managing alcohol withdrawal.

Ghrelin, through action on its receptor, GH secretagogue receptor type 1a (GHS-R1a), exerts a variety of metabolic functions including stimulation of appetite and weight gain and suppression of insulin secretion. In the present study, we examined the effects of novel small-molecule GHS-R1a antagonists on insulin secretion, glucose tolerance, and weight loss. Ghrelin dose-dependently suppressed insulin secretion from dispersed rat islets. This effect was fully blocked by a GHS-R1a antagonist. Consistent with this observation, a single oral dose of a GHS-R1a antagonist improved glucose homeostasis in an ip glucose tolerance test in rat. Improvement in glucose tolerance was attributed to increased insulin secretion. Daily oral administration of a GHS-R1a antagonist to diet-induced obese mice led to reduced food intake and weight loss (up to 15%) due to selective loss of fat mass. Pair-feeding experiments indicated that weight loss was largely a consequence of reduced food intake. The impact of a GHS-R1a antagonist on gastric emptying was also examined. Although the GHS-R1a antagonist modestly delayed gastric emptying at the highest dose tested (10 mg/kg), delayed gastric emptying does not appear to be a requirement for weight loss because lower doses produced weight loss without an effect on gastric emptying. Consistent with the hypothesis that ghrelin regulates feeding centrally, the anorexigenic effects of potent GHS-R1a antagonists in mice appeared to correspond with their brain exposure. These observations demonstrate that GHS-R1a antagonists have the potential to improve the diabetic condition by promoting glucose-dependent insulin secretion and promoting weight loss.

Compounds that simultaneously activate the three peroxisome proliferator-activated receptor (PPAR) subtypes alpha, gamma, and delta hold potential to address the adverse metabolic and cardiovascular conditions associated with diabetes and the metabolic syndrome. We recently identified the indanylacetic acid moiety as a well-tunable PPAR agonist head group. Here we report the synthesis and structure-activity relationship (SAR) studies of novel aryl tail group derivatives that led to a new class of potent PPAR pan agonists. While most of the tail group modifications imparted potent PPAR delta agonist activity, improvement of PPAR alpha and gamma activity required the introduction of new heterocyclic substituents that were not known in the PPAR literature. Systematic optimization led to the discovery of 4-thiazolyl-phenyl derivatives with potent PPAR alpha/gamma/delta pan agonistic activity. The lead candidate from this series was found to exhibit excellent ADME properties and superior therapeutic potential compared to known PPAR gamma activating agents by favorably modulating lipid levels in hApoA1 mice and hyperlipidemic hamsters, while normalizing glucose levels in diabetic rodent models.

A female resident of Townsville, Queensland, Australia has been diagnosed with Zika virus infection following a recent trip to the Cook Islands. An initial serum sample collected in March, 2014 was positive by two separate Zika virus TaqMan real-time RT-PCRs and a pan-Flavivirus RT-PCR. Nucleotide sequencing and phylogenetics of the complete Cook Islands Zika virus envelope gene revealed 99.1% homology with a previous Cambodia 2010 sequence within the Asian lineage. In addition, IgG and IgM antibody seroconversions were detected between paired acute and convalescent phase sera using recombinant Zika virus serology assays. This is the first known imported case of Zika virus infection into northern Queensland where the potential mosquito vector Aedes aegypti is present and only the second such reported case diagnosed within Australia.
RESUMEN
INTRODUCTION AND AIMS: Tobacco use and heavy alcohol consumption are associated with increased morbidity and mortality. There is limited research on the correlation between tobacco and risky levels of alcohol use and the possible complications associated with a hospital admission. The underestimation of problem drinking, in particular, has obvious repercussions for the management of patients in hospital. If alcohol-related problems go undetected or unrecorded, treatment may be inadequate or inappropriate. The aims of the project were to assess the prevalence of high-risk alcohol and tobacco use in orthopaedic in-patients and to examine any relationship between alcohol and tobacco use and the number and type of complications, management and length of stay. DESIGN AND METHOD: One hundred and fifty-three consecutive orthopaedic admissions to the Orthopaedic Ward at Lismore Base Hospital were screened using the Drinkcheck questionnaire, which is based on the Alcohol Use Disorders Identification Test (AUDIT), but which also screens for tobacco use. Nursing staff on the ward completed a Complications Evaluation Questionnaire (CEQ). The risk status of the subjects was compared to the number and type of complications, to assess any effects of alcohol and tobacco on post-surgical complications. RESULTS: Significant correlations were found between tobacco use, hazardous and harmful alcohol use and numerous medical complications and behavioural problems. Behavioural problems associated with risky alcohol use included verbal abuse, agitation and sleep disturbances, particularly in men; problems associated with tobacco use included agitation and non-compliance. DISCUSSION AND CONCLUSIONS: Orthopaedic patients who smoke and/or drink heavily prior to surgery may have more non-medical complications than non-smokers and light or non-drinkers. All surgery patients should thus be screened for alcohol and tobacco use and alcohol withdrawal, which may cause other symptoms such as behavioural problems, non-compliance and verbal abuse post-surgery.

Modulation of PPAR activities represents an attractive approach for the treatment of diabetes with associated cardiovascular complications. The indanylacetic acid structural motif has proven useful in the generation of potent and tunable PPAR ligands. Modification of the substituents on the linker and the heterocycle tail group allowed for the modulation of the selectivity at the different receptor subtypes. Compound 33 was evaluated in vivo, where it displayed the desired reduction of glucose levels and increase in HDL levels in various animal models.

Modulation of cAMP levels has been linked to insulin secretion in preclinical animal models and in humans. The high expression of PDE-10A in pancreatic islets suggested that inhibition of this enzyme may provide the necessary modulation to elicit increased insulin secretion. Using an HTS approach, we have identified quinoline-based PDE-10A inhibitors as insulin secretagogues in vitro. Optimized compounds were evaluated in vivo where improvements in glucose tolerance and increases in insulin secretion were measured.
