Abstract
BACKGROUND Surgical site infection (SSI) surveillance aims to facilitate a reduction in SSIs through identifying infection rates, benchmarking, triggering clinical review and instituting infection control measures. Participation in surveillance is, however, variable suggesting opportunities to improve wider adoption. AIM To gain an in-depth understanding of the barriers and facilitators for SSI surveillance in a high-income European setting. METHODS Key informant interviews with 16 surveillance staff, infection prevention staff, nurses and surgeons from nine cardiac hospitals in England. Data were analysed thematically. FINDINGS SSI surveillance was reported to be resource intensive. Barriers to surveillance included challenges associated with data collection: data being located in numerous places, multiple SSI data reporting schemes, difficulty in finding denominator data, lack of interface between computerized systems, 'labour intensive' or 'antiquated' methods to collect data (e.g., using postal systems for patient questionnaires). Additional reported concerns included: relevance of definitions, perceived variability in data reporting, lack of surgeon engagement, unsupportive managers, low priority of SSIs among staff, and a 'blame culture' around high SSI rates. Facilitators were increased resources, better use of digital technologies (e.g., remote digital wound monitoring), integrating surveillance within routine clinical work, having champions, mandating surveillance, ensuring a closer relationship between surveillance and improved patient outcomes, increasing the focus on post-discharge surveillance, and integration with primary care data. CONCLUSION Using novel interviews with 'front-line' staff, identified opportunities for improving participation in SSI surveillance. Translating these findings into action will increase surveillance activity and bring patient safety benefits to a larger pool of surgical patients.

Type of funding sources: Public Institution(s). Main funding source(s): Australian Catholic University, Australia
Background
Patients with heart failure or type 2 diabetes often experience bothersome symptoms (e.g., swelling, dizziness) and need clinical support with symptom management to reduce the impact of these symptoms. Knowledge about recommended self-care management behaviors by experienced clinicians can help to guide the development of more effective self-care interventions.
Purpose
To develop a list of common bothersome symptoms of heart failure and type 2 diabetes and of self-care management behaviors that clinicians recommend to patients to reduce the impact of these symptoms.
Methods
A two-round Delphi study among a panel of 37 nurses and physicians (heart failure only n=14; type 2 diabetes only n=11 and both heart failure and type 2 diabetes n=12) from Italy, the Netherlands, Sweden and the US was performed. Online surveys were used to identify common and bothersome symptoms and related self-care management behaviors that they recommend to patients with heart failure or type 2 diabetes. Self-care management behaviors that received at least 75% agreement were retained and similar self-care management behaviors were discussed and merged to reduce redundancy.
Results
For heart failure, the final list included 12 common bothersome symptoms (e.g., fatigue/tiredness, shortness of breath) and 51 related self-care management behaviors (e.g., balance rest & activity, check body weight & swelling). For type 2 diabetes, 11 common bothersome symptoms (e.g., hypo- and hyperglycemia symptom clusters, foot wounds) and 25 related self-care management behaviors (e.g., check blood sugar, take insulin, contact podiatrist) were included in the final list. Consensus was reached on the vast majority (70%) of recommended behaviors.
Conclusion
The lists of common bothersome symptoms and self-care management behaviors reflect consensus but also discrepancies between clinicians’ recommendations and current guidelines. Efforts to enhance and align the use of proven effective self-care management behaviors to reduce symptom impact in routine care by clinicians should be considered.

Abstract
Branched-chain amino acids (BCAA) and their cognate α-ketoacids (BCKA) are elevated in an array of cardiometabolic diseases. Here we demonstrate that the major metabolic fate of uniformly-13C-labeled α-ketoisovalerate ([U-13C]KIV) in the heart is reamination to valine. Activation of cardiac branched-chain α-ketoacid dehydrogenase (BCKDH) by treatment with the BCKDH kinase inhibitor, BT2, does not impede the strong flux of [U-13C]KIV to valine. Sequestration of BCAA and BCKA away from mitochondrial oxidation is likely due to low levels of expression of the mitochondrial BCAA transporter SLC25A44 in the heart, as its overexpression significantly lowers accumulation of [13C]-labeled valine from [U-13C]KIV. Finally, exposure of perfused hearts to levels of BCKA found in obese rats increases phosphorylation of the translational repressor 4E-BP1 as well as multiple proteins in the MEK-ERK pathway, leading to a doubling of total protein synthesis. These data suggest that elevated BCKA levels found in obesity may contribute to pathologic cardiac hypertrophy via chronic activation of protein synthesis. Systemic modulation of branched-chain keto acid (BCKA) metabolism alters cardiac health. Here, the authors define the major fates of BCKA in the heart and demonstrate that acute exposure to BCKA levels found in obesity activates cardiac protein synthesis and markedly alters the heart phosphoproteome.

Abstract
Elevations in circulating levels of branched-chain amino acids (BCAAs) are associated with a variety of cardiometabolic diseases and conditions. Restriction of dietary BCAAs in rodent models of obesity lowers circulating BCAA levels and improves whole-animal and skeletal-muscle insulin sensitivity and lipid homeostasis, but the impact of BCAA supply on heart metabolism has not been studied. Here, we report that feeding a BCAA-restricted chow diet to Zucker fatty rats (ZFRs) causes a shift in cardiac fuel metabolism that favors fatty acid relative to glucose catabolism. This is illustrated by an increase in labeling of acetyl-CoA from [1-13C]palmitate and a decrease in labeling of acetyl-CoA and malonyl-CoA from [U-13C]glucose, accompanied by a decrease in cardiac hexokinase II and glucose transporter 4 protein levels. Metabolomic profiling of heart tissue supports these findings by demonstrating an increase in levels of a host of fatty-acid-derived metabolites in hearts from ZFRs and Zucker lean rats (ZLRs) fed the BCAA-restricted diet. In addition, the twofold increase in cardiac triglyceride stores in ZFRs compared with ZLRs fed on chow diet is eliminated in ZFRs fed on the BCAA-restricted diet. Finally, the enzymatic activity of branched-chain ketoacid dehydrogenase (BCKDH) is not influenced by BCAA restriction, and levels of BCAA in the heart instead reflect their levels in circulation. In summary, reducing BCAA supply in obesity improves cardiac metabolic health by a mechanism independent of alterations in BCKDH activity.

Abstract
Background:
Patients with diabetes mellitus (DM) have a higher risk of heart failure (HF). While metabolic dysregulation has been well-established in HF and DM separately, molecular mechanisms associated with diabetic HF are incompletely understood. Thus, we sought to test the overarching hypothesis that cardiac metabolic programming is distinct in diabetic HF compared to DM and HF individually.
Methods:
RNA-sequencing and targeted metabolomics profiles were completed on human myocardial tissue from 54 unique individuals received from the Duke Human Heart Biorepository and the University of Colorado. Multi-omics profiles of cardiac tissue from 4 groups were compared: a) controls with no clinical evidence of DM or HF (n = 12), b) DM-only (n = 15), c) HF-only (n = 10), and d) HF+DM (n = 17).
Results:
After using statistical criteria to prioritize genes, we looked for genes that function together or modulate the same activity. Genes encoding producers of reactive oxygen species (ROS), DUOX2, DUOXA2, and DUOXA1, were differentially upregulated in diabetic-HF, compared to DM or HF alone (FDR HF+DM vs DM-only/HF-only = 6.6 x 10

/2.2 x 10
-4
, 7.7 x 10
-3
/6.7 x 10

, and 3.6 x 10

/0.013, respectively). Modulators of mTOR signaling, ERBB3, ERBB4, and PIK3R3, were also differentially regulated in diabetic-HF (FDR HF+DM vs DM-only/HF-only = 1.4 x 10
-3
/0.010, 0.012/7.4 x 10
-3
, and 0.011/9.3 x 10
-3
, respectively). Gene set enrichment analysis supported our focus on these genes; top enriched gene sets included mTOR signaling and processes related to oxidative stress response. In our metabolomics data, long chain acylcarnitines (AC) and ceramides (Cer) are decreased in diabetic-HF. For example, C20:1 AC can be converted to C20:1 Cer and accumulation of both is diminished in diabetic-HF (FDR = 0.0032 and 0.035, respectively).
Conclusions:
We found that diabetic-HF was characterized by a distinct omics profile consistent with increased ROS production, diminished AC and Cer accumulation, and modulation of mTOR signaling. The fact that ceramide accumulation has been previously associated with oxidative stress and also linked to ERBB and PI3K pathways suggests that these data may reveal a unique regulation of these pathways in diabetic-HF.

Abstract
Abstract
Background: Aromatase inhibitors are a mainstay hormone receptor-positive breast cancer treatment. AIA occur in up to 50% of patients (pts), adversely affecting quality of life and treatment compliance. A small phase II clinical trial of oral testosterone unedeconate appeared to improve AIA over placebo (P), with no significant androgenic side effects. The current study was performed to confirm these findings.
Methods: This randomized P-controlled trial enrolled postmenopausal women on adjuvant anastrozole or letrozole and experiencing moderate-to-severe AIA (≥5 on 0-10 scale). Pts were initially randomized to receive a subcutaneous pellet containing T 120 mg + anastrozole 8 mg (T+AIpellet) or P at the end of the first week on study (after obtaining baseline hot flash data) and at 3 months (mo). Due to slow accrual, the protocol was amended to change the route of delivery to topical T or P applied to the skin once daily for 6 mo. Baseline and monthly questionnaires were administered, including: Modified Brief Pain Inventory for aromatase arthralgia (BPI-AIA), prolife of mood states (POMS), the menopause specific quality of life questionnaire (MENQOL), a hot flash diary, the hot flash related daily interference scale (HFRDIS) and a symptom experience questionnaire. The primary endpoint was intra-patient change in joint pain at 3 mo, compared using a two-sample t-test.
Results: 227 pts were accrued between 9/1/2013-11/29/2017. 55 pts were randomized prior to the protocol amendment and received T+AIpellet or P. Baseline characteristics were balanced between arms, with the exceptions of median weight, BMI, hemoglobin (all higher in T arm), and breast tenderness, dissatisfaction with personal life/depression, and skin changes (all higher in P arm). Compared to baseline, there were no significant differences between T and P in average pain or joint stiffness at 3 (p=0.483) or 6 mo (p=0.573). Average pain was significantly lower each month compared to baseline, irrespective of treatment arm. There were no significant differences in any other items evaluated by BPI-AIA, POMS, MENQOL, hot flash diary or HFRDIS. Similarly, there were no substantial differences in toxicity. A subset analysis of the 55 pts randomized to receive T+AIpellet or P identified significant reductions in average pain scores with T+AIpellet during the first month (p=0.038), but not thereafter. T+AIpellet pts had significantly more reduction in reported % of baseline hot flash frequency (p=0.034) and score (p=0.031), nausea (p=0.019), fatigue (p=0.042), mood swings (p=0.026), hand/feet swelling (p=0.009), stress urinary incontinence (p=0.039) and changes in appearance, texture or tone of their skin (p=0.0083), than pts on P.
Conclusions: Overall, T did not improve AIA or menopausal symptoms compared to P. While there was significant improvement in AIA over the study period, T did not facilitate this process. However, T+AIpellet was associated with improvement in short-term AIA and several menopausal symptoms compared to P, suggesting that subcutaneous T combined with anastrozole may be superior to transdermal T alone.

Abstract
BACKGROUND Recent violence reduction initiatives in Glasgow have led to a reduction in recorded levels of violent crime.(1) This study evaluates the impact of these initiatives on assault-related emergency department attendances and admissions. METHODS A retrospective observational study conducted in Glasgow Royal Infirmary's emergency department comparing assault-related emergency department attendances and hospital admissions over two 30-day study periods (April 2010 and April 2012). The primary outcome measure was the change in assault-related emergency department attendances. The secondary outcome measure was the impact on assault-related hospital and critical care admissions. RESULTS In April 2010, there were 6098 emergency department attendances, 301 (4.9%) were due to assault. In April 2012, there were 7236 emergency department attendances, 263 (3.6%) were due to assault, representing a significant reduction in assault-related attendances (p < 0.01). There were significant reductions in level 1 admissions 2010 n = 56 (19.2%), 2012 n = 36 (14.0%) p = 0.04 and critical care admissions, 2010 n = 5 (1.7%), 2012 n = 1 (0.4%) p = 0.04. CONCLUSIONS Violence reduction initiatives in Glasgow have contributed to a reduction in assault-related emergency department attendance at Glasgow Royal Infirmary. The reduction in hospital admissions, in particular critical care admissions, suggests a reduction in morbidity and cost to the National Health Service.

Abstract
It is expedient to consider new ways in which dementia care services may be configured to meet increasing demographic, societal and regulatory demands. Greater equity in the distribution of clinical responsibility across multidisciplinary teams has been suggested as one method that may offer a range of benefits to both the service user and the service itself. However, within the dementia workforce there are concerns about inconsistency and variability in both knowledge of dementia and competency in meeting the needs of those affected. Taking this into account it was felt important to explore perceived knowledge and competency of specialist dementia care nurses who would not only be expected to possess higher levels of knowledge and skill but are positioned as the obvious clinical group to engage with new ways of working. Consequently, this paper offers the results and subsequent discussion of a survey of senior nurses working in dementia care across the UK.

Abstract
Obesity has become a worldwide epidemic and can lead to multiple chronic diseases. Adipose tissue is increasingly thought to play an active role in obesity-related pathologies such as insulin resistance and non-alcoholic fatty liver disease. Obesity has been strongly associated with systemic inflammation and, to a lesser degree, with oxidative stress, although the causal relationships among these factors are unclear. A recent study demonstrating an expression of the components of the melanogenic pathway and the presence of melanin in visceral adipose has raised questions regarding the possible role of melanogenesis in adipose tissue. As this study also found larger amounts of melanin in the adipose tissue of obese patients relative to lean ones, we hypothesize that melanin, a pigment known for its antioxidant and anti-inflammatory properties, may scavenge reactive oxygen species and abate oxidative stress and inflammation in adipose tissue. This review considers the evidence to support such a hypothesis, and speculates on the role of melanin within adipocytes. Furthermore, we consider whether the α-melanocyte-stimulating hormone or its synthetic analogues could be used to stimulate melanin production in adipocytes, should the hypothesis be supported in future experiments.

Abstract
Dysnatraemic disorders are becoming more common with increased use of biochemical tests in routine practice. Although hyponatraemia is generally much commoner than hypernatraemia, the latter is found in a variety of clinical situations. This review article aims to explain the approach to assessment and strategies for management of hypernatraemia, complications of its treatment and the steps that can be taken for prevention of recurrence.

Abstract
OBJECTIVES To compare nurse initial diagnoses following domiciliary visits with subsequent formal multidisciplinary formulation based upon the full possession of investigations, neuropsychological tests and brain imaging. DESIGN Retrospective case note study. SETTING Home-based nurse assessments, secondary care based multidisciplinary memory clinic. PARTICIPANTS Four hundred and four consecutive referrals over an 18-month period. RESULTS One hundred and seventy-five patients (43.3%) were diagnosed by the multi-disciplinary team as having a dementia. Seventy-three (41.5%) were classified as Alzheimer's disease, 81 (46%) of mixed sub-type and 20 (11.4%) of vascular origin. Overall nurse-MDT diagnosis agreement was 0.88 (Kappa = 0.82). Together, two nurses were able to detect dementia with 94% accuracy (Kappa = 0.88) Sensitivity was 92% and specificity 96%. The positive and negative predictive values of their judgements were 94% and 98% respectively. Nurses were able to sub-diagnose dementia with 86% (kappa = 0.76) accuracy. Multivariate logistic regression modelling showed a MDT dementia diagnosis to be independently and significantly associated with lower scores on the KOLT and total MMSE, and with the absence of biological markers of depression. Nurse dementia diagnoses were associated with lower KOLT scores and the absence of biological depression markers, high past alcohol consumption or a history of hypercholesteraemia. CONCLUSIONS In this study, structured initial assessment by a specialist nurse was shown to be an accurate method of determining a diagnosis of cognitive impairment, when compared with formal MDT judgement. The principal benefit of this approach was that signposting to subsequent care pathways was expedited. Arguably, such distributed responsibility affords a viable option for the future detection of early dementia.

Abstract
We have measured the beam-normal single-spin asymmetry in elastic scattering of transversely polarized 3 GeV electrons from unpolarized protons at Q2=0.15, 0.25 (GeV/c)2. The results are inconsistent with calculations solely using the elastic nucleon intermediate state and generally agree with calculations with significant inelastic hadronic intermediate state contributions. A(n) provides a direct probe of the imaginary component of the 2gamma exchange amplitude, the complete description of which is important in the interpretation of data from precision electron-scattering experiments.

Abstract
The fate and phenotype of lesion macrophages is regulated by cellular oxidative stress. Thioredoxin-1 (Trx-1) plays a major role in the regulation of cellular redox balance, with resultant effects on gene expression and cellular responses including cell growth and death. Trx-1 activity is inhibited by interaction with vitamin D-upregulated protein-1 (VDUP-1). Peroxisome proliferator-activated receptor gamma (PPARgamma) is expressed by human monocyte-derived macrophages (HMDM) and PPARgamma agonism has been reported to decrease expression of inflammatory genes and to promote apoptosis of these cells. To determine whether VDUP-1 may be involved in regulating the effects of PPARgamma agonists in macrophages, we investigated the effect of a synthetic PPARgamma agonist (GW929) on the expression of VDUP-1 in HMDM. GW929 concentration-dependently increased HMDM expression of VDUP-1 (mRNA and protein). Transfection of different fragments of the VDUP-1 promoter as well as gel shift analysis revealed the presence of functional PPARgamma response elements (PPRE) in the promoter. Under conditions in which PPAR agonism altered levels of VDUP-1, caspase-3 activity, and macrophage apoptosis were also elevated. The results suggest that PPARgamma activation stimulates apoptosis in human macrophages by altering the cellular redox balance via regulation of VDUP-1.

Abstract
The European Food Safety Authority (EFSA) and the World Health Organization (WHO), with the support of the International Life Sciences Institute, European Branch (ILSI Europe), organized an international conference on 16-18 November 2005 to discuss how regulatory and advisory bodies evaluate the potential risks of the presence in food of substances that are both genotoxic and carcinogenic. The objectives of the conference were to discuss the possible approaches for risk assessment of such substances, how the approaches may be interpreted and whether they meet the needs of risk managers. ALARA (as low as reasonably achievable) provides advice based solely on hazard identification and does not take into account either potency or human exposure. The use of quantitative low-dose extrapolation of dose-response data from an animal bioassay raises numerous scientific uncertainties related to the selection of mathematical models and extrapolation down to levels of human exposure. There was consensus that the margin of exposure (MOE) was the preferred approach because it is based on the available animal dose-response data, without extrapolation, and on human exposures. The MOE can be used for prioritisation of risk management actions but the conference recognised that it is difficult to interpret it in terms of health risk.

Abstract
BACKGROUND Mast cell microlocalisation within the airway smooth muscle (ASM) bundle is an important determinant of the asthmatic phenotype. We hypothesised that mast cells migrate towards ASM in response to ASM derived chemokines. METHODS Primary ASM cultures from subjects with and without asthma were stimulated with interleukin (IL)-1beta, IL-4, and IL-13 alone and in combination. Mast cell chemotaxis towards these ASM supernatants was investigated, and the chemotaxins mediating migration by using specific blocking antibodies for stem cell factor (SCF) and the chemokine receptors CCR3, CXCR1, 3 and 4 as well as the Gi inhibitor pertussis toxin and the tyrosine kinase inhibitor genistein were defined. The concentrations of CCL11, CXCL8, CXCL10, TGF-beta, and SCF in the supernatants were measured and the effect of non-asthmatic ASM supernatants on the mast cell chemotactic activity of asthmatic ASM was examined. RESULTS Human lung mast cells and HMC-1 cells migrated towards Th2 stimulated ASM from asthmatics but not non-asthmatics. Mast cell migration was mediated through the combined activation of CCR3 and CXCR1. CCL11 and CXCL8 expression by ASM increased markedly after stimulation, but was similar in those with and without asthma. ASM supernatants from non-asthmatics inhibited mast cell migration towards the asthmatic ASM supernatant. CONCLUSION Th2 stimulated ASM from asthmatics is chemotactic for mast cells. Non-asthmatic ASM releases a mediator or mediators that inhibit mast cell migration towards stimulated asthmatic ASM. Specifically targeting mast cell migration into the ASM bundle may provide a novel treatment for asthma.

Abstract
We have measured parity-violating asymmetries in elastic electron-proton scattering over the range of momentum transfers 0.12 < or =Q2 < or =1.0 GeV2. These asymmetries, arising from interference of the electromagnetic and neutral weak interactions, are sensitive to strange-quark contributions to the currents of the proton. The measurements were made at Jefferson Laboratory using a toroidal spectrometer to detect the recoiling protons from a liquid hydrogen target. The results indicate nonzero, Q2 dependent, strange-quark contributions and provide new information beyond that obtained in previous experiments.

Abstract
Anticholinesterases are known to be effective against cognitive and non-cognitive symptoms of Alzheimer's disease (AD) but their effect on the personality changes in the disease is not known. This study examines the effect of anticholinesterase treatment on personality changes in AD. It involved the carers of patients with mild to moderate AD who were currently receiving anticholinesterases in south Manchester. The personality change was measured using the Brooks and McKinlay Personality Inventory. The carers were asked to complete the inventory for each of three periods in the patients' lives: before the onset of AD, after the diagnosis of AD but before starting anticholinesterases, and currently on anticholinesterases. Fifty-eight carers participated in the study. Personality became more negative (total score on the personality inventory became less) following the onset of AD (p < 0.001). Following anticholinesterase treatment, the total score on the personality inventory remained the same or increased in 23 (39%) patients. Scores on individual personality traits remained the same or increased in the majority of patients. In approximately one fifth of the patients, the traits 'does things himself', 'happy', 'calm' and 'cautious' showed improvement on anticholinesterases. The study confirms that personality changes are almost universal and negative in AD and suggests that anticholinesterases may have a positive effect. Further double blind prospective studies are needed to understand natural progression of personality changes in AD and to validate the findings of this study.

Abstract
NF-kappaB/Rel transcription factors are modulators of immune and inflammatory processes and are also involved in malignancy. Phosphorylation of the IkappaB inhibitors by the IkappaB kinase (IKK) complex leads to their proteasomal degradation, resulting in activated NF-kappaB. Here, we investigated the activation status of NF-kappaB and the IKK complex in acute myeloid leukemia (AML). Gelshift assays revealed an increased level of activated nuclear NF-kappaB in myeloid blasts. Both bone marrow and peripheral blood blasts from AML patients showed enhanced IKK activity relative to controls, whereas the IKK protein concentrations were comparable. In addition, an increased level of IkappaB-alpha was detected in AML blast cells, although this appeared to be insufficient to block nuclear translocation of NF-kappaB, also confirmed by immunofluorescence. In subtype M4 and M5 AML cells a more extensive NF-kappaB activation and higher IKK activity was found than in M1/M2 specimens. Isolated AML blasts cultured ex vivo responded to external stimulation (TNF, LPS) by further IKK activation, IkappaB degradation and NF-kappaB activation. Preincubation with the proteasome inhibitor PSI inhibited the NF-kappaB system in isolated AML blasts. This study established for the first time a dysregulation of IKK signaling in AML leading to increased NF-kappaB activity suggesting potential therapeutic avenues.

Abstract
Asthma is characterized by inflammation, hyperresponsiveness, and remodeling of the airway. Human mast cells (HMCs) play a central role in all of these changes by releasing mediators that cause exaggerated bronchoconstriction, induce human airway smooth muscle (HASM) cell proliferation, and recruit and activate inflammatory cells. Moreover, the number of HMCs present on asthmatic HASM is increased compared with that on nonasthmatic HASM. HASM cells also have the potential to actively participate in the inflammatory process by synthesizing cytokines and chemokines and expressing surface molecules, which have the capacity to perpetuate the inflammatory mechanisms present in asthma. This review specifically examines how the mediators of HMCs have the capacity to modulate many functions of HASM; how the synthetic function of HASM, particularly through the release and expression of stem cell factor, has the potential to influence HMC number and activation in an extraordinarily potent and proinflammatory manner; and how these interactions between HMCs and HASM have potential consequences for airway structure and inflammation relevant to the disease process of asthma.

Abstract
The use of genotypic assays for determining drug resistance in human immunodeficiency virus (HIV) type 1 (HIV-1)-infected patients is increasing. These tests lack standardization and validation. The aim of this study was to evaluate several tests used for the determination of HIV-1 drug resistance. Two genotypic tests, the Visible Genetics TruGene HIV-1 Genotyping Kit and the Applied Biosystems HIV Genotyping System, were compared using 22 clinical samples. Genotyping results were also obtained from an independent reference laboratory. The Visible Genetics and Applied Biosystems genotyping tests identified similar mutations when differences in the drug databases and reference strains were taken into account, and 19 of 21 samples were equivalent. The concordance between the two assays was 99% (249 of 252 mutation sites). Mutations identified by the reference laboratory varied the most among those identified by the three genotypic tests, possibly because of differences in the databases. The concordance of the reference laboratory results with the results of the other two assays was 80% (201 of 252). Samples with 500 to 750 HIV RNA copies/ml could be sequenced by the Visible Genetics and Applied Biosystems assays using 1 ml of input. The Visible Genetics and Applied Biosystems assays both generated an accurate sequence. However, the throughput of the Visible Genetics assay is more limited and may require additional instruments. The two assays differ technically but are similar in overall complexity. Data analysis in the two assays is straightforward, but only the reports provided by Visible Genetics contain information relating mutations to drug resistance. HIV drug resistance genotyping by sequencing is a complex technology which presents a challenge for analysis, interpretation, and reporting.

Abstract
The paper reports findings from a multidisciplinary programme of research, the major aims of which were to determine the nature and extent of the New Zealand adventure tourism injury problem. Analysis of hospital discharge and mortality data for a 15-year period identified adventure tourism-related activities as contributing to approximately 20% of overseas visitor injuries, and 22% of fatalities. Activities that commonly involve independent-unguided adventure tourism, notably mountaineering, skiing and tramping, contributed most to injury and fatality incidence. Horse riding and cycling activities were identified from hospital discharge data and adventure tourism operators' reported client injury-incidence, as the commercial adventure tourism activities most frequently involved in client injuries. Falls were the most common injury events, and a range of client, equipment, environmental and organisational risk factors were identified. Possible interventions to reduce injury risk among overseas and domestic adventure tourists are discussed.

Abstract
A critical perspective is presented in regard to the 2000 regional rankings of Canadian health care indices by Maclean's magazine, June 5, 2000. This perspective is related in format to previous analyses of the Maclean's rankings of Canadian universities. Several pitfalls in the health care ranking procedures are summarized. The Maclean's data and general criteria appear conceptually reasonable, but their inconsistencies and limited range, together with problems in interpretation of rank data, do not allow them to be logically or empirically useful in the matter of health care evaluation, that is, in the manner portrayed for readers of Maclean's. Using a particular set of parameters defined as health "indicators," the rank data show gratuitously that communities better endowed with certain health services, such as those with medical schools, tend to provide higher levels of care.

Abstract
OBJECTIVE Activated platelets induce alterations of chemotactic and adhesive properties of endothelial cells, a critical initial step in atherogenesis. We investigated the effect of transient interaction of activated platelets with cultured human umbilical vein endothelial cells (HUVECs) on secretion of monocyte chemoattractant protein-1 (MCP-1), a key molecule in monocyte chemotaxis and transmigration. METHODS AND RESULTS Transient interaction of alpha-thrombin-activated platelets with endothelial cells for 10-120 min substantially induced endothelial secretion of MCP-1, monocyte chemotaxis and adhesion to HUVECs. Platelet-induced secretion of MCP-1 and monocyte-endothelium adhesion was reduced by the MAP kinase p38-specific inhibitor SB203580, but not by other kinase inhibitors including PD98059, wortmannin, or rapamycin. In addition, activated platelets induced transcription of a luciferase reporter construct containing a MCP-1 promotor, an effect that could be inhibited by SB203580. Overexpression of dominant-negative mutants of MAP kinase p38, CSBP2-(D168A) and CSBP2-(T180E,Y182E) reduced platelet-induced expression of MCP-1. CONCLUSIONS Activation of the p38 MAP kinase and consecutive endothelial secretion of MCP-1 induced through transient interaction of activated platelets might play an important role in atherogenesis.

Abstract
AIM To assess the use of the Heidelberg retina tomograph (HRT) in screening for sight threatening diabetic macular oedema in a hospital diabetic clinic, using a new subjective analysis system (SCORE). METHODS 200 eyes of 100 consecutive diabetic patients attending a diabetologist's clinic were studied, all eyes had an acuity of 6/9 or better. All patients underwent clinical examination by an ophthalmologist. Using the HRT, one good scan was obtained for each eye centred on the fovea. A System for Classification and Ordering of Retinal Edema (SCORE) was developed using subjective assessment of the colour map and the reflectivity image. The interobserver agreement of using this method to detect macular oedema was assessed by two observers (ophthalmic trainees) who were familiarized with SCORE by studying standard pictures of eyes not in the study. All scans were graded from 0-6 and test positive cases were defined as having a SCORE value of 0-2. The sensitivity of SCORE was assessed by pooling the data with an additional 88 scans of 88 eyes in order to reduce the confidence interval of the index. RESULTS 12 eyes in eight out of the 100 patients had macular oedema clinically. Three scans in three patients could not be analysed because of poor scan quality. In the additional group of scans 76 out of 88 eyes had macular oedema clinically. The scoring system had a specificity of 99% (95% CI 96-100) and sensitivity of 67% (95% CI 57-76). The predictive value of a negative test was 87% (95% CI 82-99), and that of a positive test was 95% (95% CI 86-99). The mean difference of the SCORE value between two observers was -0.2 (95% CI -0.5 to +0.07). CONCLUSIONS These data suggest that SCORE is potentially useful for detecting diabetic macular oedema in hospital diabetic patients.

Abstract
This paper draws on a small scale, exploratory study which was conducted in the clinical area in the early 1990s (Page 1992). The study drew on the principles of reflective practice in order to enable practitioners to identify learning needs in relation to cardiopulmonary resuscitation (CPR) procedures. Whilst considerable benefit from the reflective sessions was noted, one unanticipated and unpalatable outcome was what might be termed professional apathy. This was manifest in several ways, most importantly in that issues 'for action', identified through reflection, were not prioritised or acted upon. Whilst partial responsibility for this may lie with the somewhat naive way in which the reflective process was facilitated, some responsibility also rests with the nurses in question. One possible explanation is that, for changes in practice to occur, the planning and management of change should form an integral part of the reflective cycle. This point has been largely absent in the reflection literature to date. Such concerns are reviewed here in the context of nurse education's ongoing involvement with the notion of reflective practice and the role of the educationalist in the clinical area. The current political backdrop of 'quality initiatives' to create and demonstrate high standards of clinical care may be useful in advancing the debate.

Abstract
This paper addresses developments regarding new pharmacological treatments for people with Alzheimer's disease such as Donepezil and Rivastigmine. Following a brief discussion of the experience of people in the early stages of Alzheimer's disease, the pharmacology associated with these new treatments is outlined. The implications of these treatments for nurses working with this client-group are fully discussed within the context of assessment, treatment and cessation. It is argued that nurses have an important contribution in the management of these treatments and recommends that descriptive and evaluative research should be undertaken relating to this new specialist area of nursing care.
