Abstract
Health practitioners often insert and maintain central venous access devices (CVADs) as part of cancer care. One in four CVADs prematurely fail, which is associated with increased mortality, morbidity and a negative impact on quality of life. To support implementation of updated guidelines, eviQ Education developed a comprehensive, peer-reviewed, evidence-based CVADs eLearning package. An evaluation indicated that the eLearning supported clinicians' practice and increased knowledge and clinical competency in CVAD insertion and management.

Abstract
BACKGROUND Restraint is widely practised within inpatient mental health services and is considered a higher-risk procedure for patients and staff. There is a sparsity of evidence in respect of the efficacy of personal protective equipment (PPE) used during restraint for reducing risk of infection. METHODS A series of choreographed restraint episodes were used to simulate contact contamination in research participants playing the roles of staff members and a patient. For comparison, one episode of simulated recording of physical observations was taken. Ultraviolet (UV) fluorescent material was used to track the simulated contact contamination, with analysis undertaken using established image registration techniques of UV photographs. This was repeated for three separate sets of PPE. RESULTS All three PPE sets showed similar performance in protecting against contamination transfer. For teams not utilising coveralls, this was dependent upon effective cleansing as part of doffing. There were similar patterns of contamination for restraint team members assigned to specific roles, with hands and upper torso appearing to be higher-risk areas. The restraint-related contamination was 23 times higher than that observed for physical observations. DISCUSSION A second layer of clothing that can be removed showed efficacy in reducing contact contamination. PPE fit to individual is important. Post-restraint cleansing procedures are currently inadequate, with new procedures for face and neck cleansing required. These findings leave scope for staff to potentially improve their appearance when donning PPE and engaging with distressed patients.

Abstract
While compassion-focused therapy (CFT) holds significant promise as an intervention for survivors of sexual abuse, a history of abuse can uniquely impact an individual's capacity to cultivate compassion and may generate a fear of compassion. Understanding the specific perspectives of sexual abuse survivors may inform the application of CFT-based interventions with this client group. Two separate focus groups were established for this purpose, one with adult female survivors of sexual abuse (n = 7) and another with sexual abuse counselors (n = 7). Transcripts were analyzed according to a consensual qualitative research design. Analysis of the survivor focus group identified two core domains, Barriers to Compassion, including poor relational templates, negative perception of self, low coping self-efficacy, and fears, resistance, and misperceptions regarding self-compassion, and Factors Supporting Compassion, including support from others, compassion for others, high coping self-efficacy, motivation and hope for change, and timing and readiness for change. Analysis of the counselor focus group revealed three domains, Therapeutic Factors to Support Compassion, including counselor authenticity and modeling, gradual introduction with consideration to individual needs, acknowledgment of suffering and offering an alternative perspective; Factors Affecting Client Readiness and Capacity, including shame, self-blame, and negative sense of self, response from others, and difficulty in changing self-critical habits; and Anticipated Outcomes, including providing a hope and recovery focus, offering an alternative perspective and coping strategy, and restoring trust. Findings are discussed in relation to clinical implications and relevance to a CFT model of intervention.

Abstract
Naturopathy is the general practice of natural therapies. It emphasizes prevention, treatment, and promotion of optimal health through therapeutic modalities which encourage the self-healing process of the body. Formalized in the 19th century by the hydrotherapy and nature cure movement in Austria and Germany, naturopathy was introduced to Australia at the turn of the 20th century. It became popular since the 1970s due to social and cultural change characterized by the post-modern philosophy, as well as government policies highlighting individual responsibility and freedom of choice. Naturopathy is one of the most popular forms of complementary medicine in Australia today with naturopaths received 4.9 million consultations annually. Naturopathic consultations are sought for a variety of conditions and, in some areas, as a form of primary care, especially by middle-aged women who have a higher education level and a higher annual income. The number of Australian naturopaths was estimated to be over 4000 in 2017 and expects to grow to over 4600 by 2022, although this number is likely to be an underestimation. Australian naturopaths, as a predominantly female profession, work mainly in private clinical practice with nutritional medicine, herbal medicine, homeopathy, as well as massage therapies being the most common modalities used. There are also signs of greater integration with community pharmacies and integrative medicine clinics in major cities. The Bachelor's degree programs in Naturopathy has just become the only accredited entry-level qualification since late 2015. Currently, there are only 5 private colleges offering naturopathic education, a far cry from the 40 over in mid-2000. The profession continues to be self-regulated. There is no barrier of entry to practice and unqualified practitioners of naturopathy can potentially do harm to the public. The registration of naturopaths remains unresolved due to fragmented representation under many professional associations, disunity among the profession, and objections by certain health care lobbyists. There is a dearth of research demonstrating efficacy of the whole practice of naturopathy in Australia, which has directed the government's decision to withdraw it from private health insurance coverage from 2019. Moving forward, the whole system research of naturopathy in Australia will be in focus with the recent establishment of a practice-based research network and an international research consortium. With increasing scrutiny from evidence-based medicine, the present and future challenge to Australian naturopaths is centered on the integration of both scientific and traditional evidence to form the foundation of a person-centered, evidence-informed practice.

Abstract
INTRODUCTION Irregular breathing motion exacerbates uncertainties throughout a course of radiation therapy. Breathing guidance has demonstrated to improve breathing motion consistency. This was the first clinical implementation of audiovisual biofeedback (AVB) breathing guidance over a course of liver stereotactic body radiotherapy (SBRT) investigating interfraction reproducibility. METHODS Five liver cancer patients underwent a screening procedure prior to CT sim during which patients underwent breathing conditions (i) AVB, or (ii) free breathing (FB). Whichever breathing condition was more regular was utilised for the patient's subsequent course of SBRT. Respiratory motion was obtained from the Varian respiratory position monitoring (RPM) system (Varian Medical Systems). Breathing motion reproducibility was assessed by the variance of displacement across 10 phase-based respiratory bins over each patient's course of SBRT. RESULTS The screening procedure yielded the decision to utilise AVB for three patients and FB for two patients. Over the course of SBRT, AVB significantly improved the relative interfraction motion by 32%, from 22% displacement difference for FB patients to 15% difference for AVB patients. Further to this, AVB facilitated sub-millimetre interfraction reproducibility for two AVB patients. CONCLUSION There was significantly less interfraction motion with AVB than FB. These findings demonstrate that AVB is potentially a valuable tool in ensuring reproducible interfraction motion.

Abstract
Child sexual abuse can have long-term negative impacts across psychological, physical, and interpersonal domains. Some of the common issues for survivors of sexual abuse include shame and self-blame, attachment-based difficulties, avoidant coping strategies, and reduced capacity for self-compassion. Compassion-focused therapy is a transdiagnostic intervention that specifically responds to these concerns. Compassion-focused therapy was originally developed for clients who experience high levels of shame and self-criticism and aims to strengthen the soothing and affiliative system through the cultivation of compassion. This article will highlight the theoretical alignment between some of the common issues and impacts associated with experiences of sexual abuse, with the core underlying principles of compassion-focused therapy. This includes (a) the capacity of the therapy's evolutionary framework to reduce perceptions of self-blame, (b) the cultivation of compassion to respond to feelings of shame, (c) acknowledgment of the role of early attachment experiences and facilitation of corrective affiliative experiences, (d) regulation of the threat-based system following trauma, and (e) provision of an alternative to avoidant-based coping by responding to distress with compassion. It is proposed that the theoretical framework and core focus and aims of compassion-focused therapy are highly applicable for survivors of sexual abuse and therefore holds significant promise as a treatment option for this client group.

Abstract
Studies have suggested that positivity can be used to estimate the prevalence of Chlamydia trachomatis in large-scale chlamydia screening programmes. A recent pilot of opportunistic screening in England estimated that the prevalence among 16–24-year-old women in Portsmouth and Wirral was 9.8% and 11.2%, respectively. This study assessed the continued validity of positivity as an approximate for prevalence. We re-analysed data from the Chlamydia Screening Pilot to estimate positivity, calculated as total positive tests divided by total tests, and compared these estimates with the previously reported prevalence, measured as the number of women testing positive divided by the total number of women screened. Overall positivity was 9.4% in Portsmouth and 11.0% in the Wirral; these estimates were not statistically different from prevalence, regardless of health-care setting, age group or symptoms. We conclude that positivity can be used as a proxy for prevalence.

Abstract
Qualitative methods are progressively being implemented by researchers for exploration within healthcare. However, there has been a longstanding and wide-ranging debate concerning the relative merits of qualitative research within the health care literature. This integrative review aimed to exam the contribution of qualitative research in burns care and subsequent rehabilitation. Studies were identified using an electronic search strategy using the databases PubMed, Cumulative Index of Nursing and Allied Health Literature (CINAHL), Excerpta Medica database (EMBASE) and Scopus of peer reviewed primary research in English between 2009 to April 2014 using Whittemore and Knafl's integrative review method as a guide for analysis. From the 298 papers identified, 26 research papers met the inclusion criteria. Across all studies there was an average of 22 participants involved in each study with a range of 6-53 participants conducted across 12 nations that focussed on burns prevention, paediatric burns, appropriate acquisition and delivery of burns care, pain and psychosocial implications of burns trauma. Careful and rigorous application of qualitative methodologies promotes and enriches the development of burns knowledge. In particular, the key elements in qualitative methodological process and its publication are critical in disseminating credible and methodologically sound qualitative research.

Abstract
OBJECTIVES The objective of this cross-sectional study was to assess the intra-rater, inter-rater and test-retest reliability and concurrent validity of lower-extremity alignment estimated from a photograph [photographic alignment (PA) angle]. METHODS A convenience sample of participants was recruited from the community. Radiopaque stickers were placed over participants' anterior superior iliac spines. One radiograph and one photograph were taken with the participant standing in a standardized position. The stickers were removed. After 30 min they were reapplied and a second photograph was taken. The hip-knee-ankle (HKA) angle was measured from each radiograph using customized imaging analysis software. The same software was used by three readers to measure the PA angle from each photograph from the first set twice, at least 2 weeks apart. One reader measured the PA angle from the second set of photographs. Reliability was tested using intraclass correlation coefficients (ICC(2,1)), Bland-Altman analyses and the minimal detectable change (MDC95). Concurrent validity was tested using a Pearson's correlation coefficient and Bland-Altman analysis. RESULTS Fifty adults participated (mean age 41.8 years; mean body mass index 24.7 kg/m(2)). The PA angle was 4.5° more varus than the HKA angle; these measures were highly correlated (r = 0.92). Intra-rater (ICC(2,1) > 0.985), inter-rater (ICC(2,1) = 0.988) and test-retest reliability (ICC(2,1) = 0.903) showed negligible bias (<0.20°). The MDC95 was 2.69°. CONCLUSIONS The PA angle may be used in place of the HKA angle if a bias of 4.5° is added. A difference of 3° between baseline and follow-up would be considered a true difference.

Abstract
Burn rehabilitation is a lengthy process associated with physical and psychosocial problems. As a critical area in burn care, the aim was to systematically synthesise the literature focussing on personal perceptions and experiences of adult burn survivors' rehabilitation and to identify factors that influence their rehabilitation. Studies were identified through an electronic search using the databases: PubMed, CINAHL, EMBASE, Scopus, PsycINFO and Trove of peer reviewed research published between 2002 and 2012 limited to English-language research with search terms developed to reflect burn rehabilitation. From the 378 papers identified, 14 research papers met the inclusion criteria. Across all studies, there were 184 participants conducted in eight different countries. The reported mean age was 41 years with a mean total body surface area (TBSA) burn of 34% and the length of stay ranging from one day to 68 months. Significant factors identified as influential in burn rehabilitation were the impact of support, coping and acceptance, the importance of work, physical changes and limitations. This review suggests there is a necessity for appropriate knowledge and education based programmes for burn survivors with consideration given to the timing and delivery of education to facilitate the rehabilitation journey.

Abstract
OBJECTIVE As part of a series of papers ['Chronobiology of mood disorders' Malhi & Kuiper. Acta Psychiatr Scand 2013;128(Suppl. 444):2-15; and 'It's time we managed depression: The emerging role of chronobiology' Malhi et al. Acta Psychiatr Scand 2013;128(Suppl. 444):1] examining chronobiology in the context of depression, this article examines recent western clinical practice guidelines (CPGs) for the treatment of depression with respect to the recommendations they make, in particular as regards chronobiological treatments, and briefly considers the implications of their methodology and approach. METHOD Five international treatment guidelines, which had been published in the past 5 years, were identified, representing North American and European views. Chosen guidelines were reviewed by the authors, and the relevant recommendations were distributed for discussion and subsequent synthesis. RESULTS Most current guidelines do not address chronobiology in detail. Chronotherapeutic recommendations are tentative, although agomelatine is considered as an option for major depression and bright light therapy for seasonal affective disorder. Sleep deprivation is not routinely recommended. CONCLUSION Recommendations are limited by the lack of reliable therapeutic markers for chronotherapeutics. Current evidence supports use of light therapy in seasonal depression, but in non-seasonal depression there is insufficient evidence to support reliance on chronotherapeutics over existing treatment modalities.

Abstract
OBJECTIVE The aim of this study was to determine canine breed predispositions for decreased serum folate or markedly decreased cobalamin concentrations. METHODS Retrospective analysis of samples from dogs that had serum folate and cobalamin concentrations measured, from 1990 to 2002 at the Comparative Gastroenterology Laboratory of Liverpool, were enrolled. A total of 13,069 samples were analysed. Those with trypsin-like immunoreactivity < 5·0 lg/L were excluded, and only breeds with at least 30 individuals tested were further analyzed. Breed predisposition was determined by calculating odds ratios and 95% confidence intervals for hypocobalaminaemia or decreased folate concentration. Significance was tested with a two-sided Fisher's exact test, and the level of statistical significance was set at P<0·05. RESULTS A total of 9960 dogs fulfilled the inclusion criteria. Forty breeds contained at least 30 individuals. Predispositions for hypocobalaminaemia were identified in shar peis, Staffordshire bull terriers, German shepherd dogs and mixed breeds. Predispositions for decreased folate concentration were found in golden retrievers and boxers. CLINICAL SIGNIFICANCE Predisposition for marked hypocobalaminaemia and decreased folate concentration differed between breeds. The shar peis had a markedly increased odds ratio for hypocobalaminaemia, as previously reported in North America, but other at-risk breeds were also identified.

Abstract
BACKGROUND Depression is associated with an increased risk of cardiovascular disease (CVD). Although the mechanism is uncertain, prothrombotic and inflammatory factors may play a role. OBJECTIVES As platelets play a key role in CVD, we determined first, whether depressed individuals had more activated platelets than non-depressed individuals and second, whether treatment of depression reduced platelet activation levels. PATIENTS/METHODS We recruited 108 depressed outpatients and 45 control subjects all without a history of CVD. After psychological assessment, the depressed patients were offered treatment with medication and/or psychotherapy. Flow cytometric markers of platelet activation and level of depression were assessed at baseline and at 4 weeks and 6 months after treatment. RESULTS Depression was associated with increased platelet activation with a higher number of circulating CD62p (0.76x10(9) L(-1) vs. 0.46, P=0.019) and CD63 (P=0.05) positive platelets compared with controls. Patients with depression also had more circulating platelet-leukocyte aggregates than controls (P<0.001). There was a positive correlation between the severity of depression and the level of platelet activation. Platelets from depressed patients were also hyperreactive to adenosine 5 -diphosphate (ADP) stimulation with increased CD62p and CD63 exposure (P=0.003 and 0.019, respectively). Six months of treatment resulted in a reduced number of circulating CD62p and CD63 positive platelets (29.84% and 53.38% decrease) and a 20.9% reduction in CD63 exposure after ADP activation. CONCLUSIONS Depression is associated with increased in vivo platelet activation and resolution of depression using psychotherapy and/or medication reduces platelet activation. These findings provide insights into the link between depression and cardiovascular risk.

Abstract
Patients with severe chronic obstructive pulmonary disease (COPD) commonly develop weight loss, muscle wasting, and consequently poor survival. Nutritional supplementation and anabolic steroids increase lean body mass, improve muscle strength, and survival in patients enrolled in comprehensive rehabilitation programs. Whether anabolic steroids are effective outside an intensive rehabilitation program is not known. We conducted a prospective, double-blind, placebo-controlled, 16-week trial to study the benefits of anabolic steroids in patients with severe COPD who did not participate in a structured rehabilitation program. Biweekly intramuscular injections of either the drug (nandrolone decanoate) or placebo were administered. Sixteen patients with severe COPD were randomized to either placebo or nandrolone decanoate. The placebo group weighed 55.32 ± 11.33 kg at baseline and 54.15 ± 10.80 kg at 16 weeks; the treatment group weighed 68.80 ± 6.58 at baseline and 67.92 ± 6.73 at 16 weeks. Lean body mass remained unchanged, 71 ± 6 vs. 71 ± 7 kg in placebo group and 67 ± 7 vs. 67 ± 7 in treatment group, at baseline and 16 weeks respectively. The distance walked on 6 min was unchanged at baseline, 8 weeks, and 16 weeks in placebo (291.17 ± 134.83, 282.42 ± 115.39, 286.00 ± 82.63 m) and treatment groups (336.13 ± 127.59, 364.83 ± 146.99, 327.00 ± 173.73 m). No improvement occurred in forced expiratory volume in one second, forced vital capacity, maximal inspiratory pressure, maximal expiratory pressure, VO2 max or 6-min walk distance or health related quality of life. Administration of anabolic steroids (nandrolone decanoate) outside a dedicated rehabilitation program did not lead to either weight gain, improvement in physiological function, or better quality of life in patients with severe COPD.

Abstract
OBJECTIVE There is increasing evidence that gene copy-number variation influences phenotypic variation. Chemokine ligand 3-like 1 (CCL3L1) is encoded by a variable copy-number gene, and binds to several pro-inflammatory cytokine receptors, including chemokine receptor 5 (CCR5). Considering lymphocyte recruitment by beta-chemokines is a feature of autoimmunity, and that the CCR5Delta32 variant is associated with protection to rheumatoid arthritis (RA), we hypothesised that CCL3L1 copy-number influences susceptibility to RA and type 1 diabetes (T1D). METHODS We measured CCL3L1 copy-number in 1136 RA cases from New Zealand (NZ) and the UK, 252 NZ T1D cases and a total of 1470 controls. All subjects were ancestrally Caucasian. RESULTS A copy-number higher than 2 (the most common copy number) was a risk factor for RA in the NZ cohort (odds ratio (OR) 1.34, 95% CI 1.08-1.66, p = 0.009) but not the smaller UK RA cohort (OR 1.09, 95% CI 0.75-1.60, p = 0.643). There was evidence for association in the T1D cohort (OR 1.46, 95% CI 0.98-2.20, p = 0.064) and in the combined RA/T1D cohort (OR 1.30, 95% CI 1.00-1.54, p = 0.003). Genetic interaction between CCL3L1 dosage and CCR5 genotype was found; the increased genetic risk conferred by higher CCL3L1 copy-number was ablated by a dysfunctional CCR5 (CCR5Delta32). CONCLUSIONS These data suggest that increased CCL3L1 expression may enhance inflammatory responses and increase the chance of autoimmune disease. Genetic interaction data were consistent with a biologically plausible model; CCR5Delta32 protects against RA and T1D by blocking signalling through the CCR5 pathway, mitigating the pro-inflammatory effects of excess CCL3L1.

Abstract
Proteomics is defined as an analysis of the full complement of proteins of a cell or tissue under given conditions. Avian proteomics, or more specifically chicken proteomics, has focussed on the study of individual tissues and organs of interest to specific researchers. Researchers have looked at skeletal muscle and growth, and embryonic development and have performed initial studies in avian disease. Traditional proteomics involves identifying and cataloguing proteins in a cell and identifying relative changes in populations between two or more states, be that physiological or disease-induced states. Recent advances in proteomic technologies have included absolute quantification, proteome simplification and the ability to determine the turnover of individual proteins in a global context. This review discusses the current developments in this relatively new field, new technologies and how they may be applied to biological questions, and the challenges faced by researchers in this ever-expanding and exciting field.

Abstract
Complaints of chronic trapezius muscle pain among computer workers have increased in prevalence during the last decade. Currently there is no clear understanding of the pathophysiological mechanisms involved in affected muscles. The major objective of this work was to determine if measurable electrophysiological differences exist between the trapezius muscles in individuals suffering from trapezius myalgia (TM) and occupation-matched pain-free control subjects. Myoelectric signal (MES) data were recorded from the upper trapezius muscle while subjects with and without myalgia performed a standardized series of postural and arm-holding tasks. MES variables reflecting muscle fatigue, muscle tension and motor control strategies were analyzed to determine their potential ability to distinguish between the two groups. One variable, RestTime, was found to be significantly different between the groups but it was not specific enough to predict group association. A multivariate logistic regression analysis yielded a model that separated the two groups with better than 70% sensitivity and 70% specificity. The variables included in the model reflect differences in trapezius muscle activity between the groups, particularly related to motor control and/or active muscle tension, but not fatigue. The model was tested using a small sample of new data, which again produced a good sensitivity (85.7%) but not specificity (42.9%). To the authors' knowledge, this is the first objective MES-based model that has successfully classified subjects with or without TM based on a simple clinical test. Further work with this model might result in understanding the pathophysiology of TM, assisting with clinical diagnosis, and testing the effect of various treatment interventions.

Abstract
We have reviewed imaging findings of 32 female patients with a proven haematological malignancy in the breast and axilla presenting to two breast units over a 13-year period. Nineteen patients had screen-detected lesions, and 13 presented to symptomatic services. The most common histological diagnosis was of non-Hodgkins lymphoma. Of the 12 patients who presented with disease in the breast, six (all with primary breast lymphoma) presented with a well-defined mass on mammography. The range of radiological appearances is, however, highly variable.

Abstract
A consequence of oxidative stress is DNA damage. The survival of Porphyromonas gingivalis in the inflammatory microenvironment of the periodontal pocket requires an ability to overcome oxidative stress caused by reactive oxygen species (ROS). 8-oxo-7,8-dihydroguanine (8-oxoG) is typical of oxidative damage induced by ROS. There is no information on the presence of 8-oxoG in P. gingivalis under oxidative stress conditions or on a putative mechanism for its repair. High-pressure liquid chromatography with electrochemical detection analysis of chromosomal DNA revealed higher levels of 8-oxoG in P. gingivalis FLL92, a nonpigmented isogenic mutant, than in the wild-type strain. 8-oxoG repair activity was also increased in cell extracts from P. gingivalis FLL92 compared to those from the parent strain. Enzymatic removal of 8-oxoG was catalyzed by a nucleotide excision repair (NER)-like mechanism rather than the base excision repair (BER) observed in Escherichia coli. In addition, in comparison with other anaerobic periodontal pathogens, the removal of 8-oxoG was unique to P. gingivalis. Taken together, the increased 8-oxoG levels in P. gingivalis FLL92 could further support a role for the hemin layer as a unique mechanism in oxidative stress resistance in this organism. In addition, this is the first observation of an NER-like mechanism as the major mechanism for removal of 8-oxoG in P. gingivalis.
