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.

Abstract
There are limited data for greenhouse gas (GHG) emissions from smallholder agricultural systems in tropical peatlands, with data for non-CO2 emissions from human-influenced tropical peatlands particularly scarce. The aim of this study was to quantify soil CH4 and N2 O fluxes from smallholder agricultural systems on tropical peatlands in Southeast Asia and assess their environmental controls. The study was carried out in four regions in Malaysia and Indonesia. CH4 and N2 O fluxes and environmental parameters were measured in cropland, oil palm plantation, tree plantation and forest. Annual CH4 emissions (in kg CH4 ha-1 year-1 ) were: 70.7 ± 29.5, 2.1 ± 1.2, 2.1 ± 0.6 and 6.2 ± 1.9 at the forest, tree plantation, oil palm and cropland land-use classes, respectively. Annual N2 O emissions (in kg N2 O ha-1 year-1 ) were: 6.5 ± 2.8, 3.2 ± 1.2, 21.9 ± 11.4 and 33.6 ± 7.3 in the same order as above, respectively. Annual CH4 emissions were strongly determined by water table depth (WTD) and increased exponentially when annual WTD was above -25 cm. In contrast, annual N2 O emissions were strongly correlated with mean total dissolved nitrogen (TDN) in soil water, following a sigmoidal relationship, up to an apparent threshold of 10 mg N L-1 beyond which TDN seemingly ceased to be limiting for N2 O production. The new emissions data for CH4 and N2 O presented here should help to develop more robust country level 'emission factors' for the quantification of national GHG inventory reporting. The impact of TDN on N2 O emissions suggests that soil nutrient status strongly impacts emissions, and therefore, policies which reduce N-fertilisation inputs might contribute to emissions mitigation from agricultural peat landscapes. However, the most important policy intervention for reducing emissions is one that reduces the conversion of peat swamp forest to agriculture on peatlands in the first place.

Abstract
OBJECTIVE The objective of this mixed methods review is to examine the effectiveness and experience of social phone programs on loneliness and/or mood in community-dwelling older adults. INTRODUCTION There is a large and growing older adult population that is burdened with loneliness. Loneliness affects both physical and mental health, and it is, therefore, imperative to examine ways of mitigating experiences of loneliness. Social phone programs are being offered through multiple organizations as a way of increasing socialization and decreasing loneliness in older adults. There is a need to examine existing data on social phone programs to determine their effectiveness and optimize their implementation. INCLUSION CRITERIA Included studies will be original qualitative, quantitative, or mixed methods research, along with gray literature, examining the use of social phone programs to address loneliness and/or mood in older adults. METHODS A convergent segregated mixed methods approach will be used, in line with the JBI methodology for mixed methods reviews. Articles will be searched in selected databases, sources of clinical trials, and gray literature. No limits have been set for language or date of publication. Two team members will select studies through title and abstract screening and then full-text screening. Critical appraisal will be performed in accordance with the standard JBI critical assessment tools, although no articles will be excluded based on this appraisal. Quantitative articles will be synthesized using meta-analysis, while a process of meta-aggregation will be used for qualitative articles. The findings will be integrated into a final report. SYSTEMATIC REVIEW REGISTRATION NUMBER PROSPERO CRD42022335119.

Abstract
This paper reports on Indigenous early career researchers' experiences of mentoring in Australian higher education, with data drawn from a longitudinal qualitative study. Interviews were conducted with 30 Indigenous participants. A consistent theme in the findings and contemporary critical literature has been a reaction against institutionalised and hierarchical cloning and investment models of mentoring that reinforce the accumulation of White cultural capital, in favour of strength-based relational models tailored to build Indigenous cultural wealth in parallel with career development. We write from an equity-based standpoint addressing mentoring as a complex and raced space where individual Indigenous ECRs articulate a desire and will to develop a successful and meaningful career, rich in cultural wealth and with their identity intact. It is our intent that these findings will also have global significance and support the more sustainable and ethical career development of First Nation early career academics in relationally like colonised contexts.

Abstract
Funding Acknowledgements
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
This paper provides a snapshot of Indigenous Early Career Researchers in Australia derived from demographic information collected in the first stage of the 'Developing Indigenous Early Career Researchers' project. Analysis of the data to date has evidenced much diversity across this cohort. However, one commonality across all Indigenous Early Career Researchers was a commitment to the value and validity of Indigenous Ways of Knowing in the higher education sector. With the use of Tribal Critical Race Theory this paper explores the ways in which Indigenous Early Career Researchers disrupt Western-based academies and schools of thought and proposes that Indigenous Early Carer Researchers grow 'pearls' of experience and knowledge within the higher education sector that are essential to the development of a richer academy and stronger Indigenous communities.

Abstract
The current paper evaluates the phytoremediation ability and physiological responses of selected resistant plant species to the hazardous levels of elements in the marble waste polluted ecosystem. Preliminary results demonstrate that all the indicator/resistant plant species i.e., Ailanthus altissima, Arundo donax, Cynodon dactylon, Erigeron canadensis, Cannabis sativa, Ficus carica, Lathyrus aphaca, Morus alba, Populus alba, Robinia pseudoacacia and Vitex negundo were the best Phyto-extractors and Phyto-stabilizers for most of the heavy metals in general and Mg, Ca, Fe, Cu and Na in particular (at p < 0.05). Structural Equation Modeling confirmed that marble waste pollution has a direct and significant (R2 =0.80) impact on proline synthesis and hence a role in combating the pollution. Chlorophyll content decreased by 4% in studied plant species when the concentration of pollutants increased. It is concluded that the studied bio-indicators - the abundant plant species of the Marble Waste Polluted Systems (MWPS) have a significant role in its remediation. Increasing proline accumulation and decreasing chlorophyll contents with an increase in pollution in the studied plants show resilience of the ecosystem in response to the external lithospheric toxicities. It is recommended that the recognized plant species could be planted abundantly to remediate the MWPS around the marble processing and other such industries and their catchments.

Abstract
The COVID-19 pandemic has caused global disruption, with the emergence of this and other pandemics having been linked to habitat encroachment and/or wildlife exploitation. High impacts of COVID-19 are apparent in some countries with large tropical peatland areas, some of which are relatively poorly resourced to tackle disease pandemics. Despite this, no previous investigation has considered tropical peatlands in the context of emerging infectious diseases (EIDs). Here, we review: (i) the potential for future EIDs arising from tropical peatlands; (ii) potential threats to tropical peatland conservation and local communities from COVID-19; and (iii) potential steps to help mitigate these risks. We find that high biodiversity in tropical peat-swamp forests, including presence of many potential vertebrate and invertebrate vectors, combined, in places, with high levels of habitat disruption and wildlife harvesting represent suitable conditions for potential zoonotic EID (re-)emergence. Although impossible to predict precisely, we identify numerous potential threats to tropical peatland conservation and local communities from the COVID-19 pandemic. This includes impacts on public health, with the potential for haze pollution from peatland fires to increase COVID-19 susceptibility a noted concern; and on local economies, livelihoods and food security, where impacts will likely be greater in remote communities with limited/no medical facilities that depend heavily on external trade. Research, training, education, conservation and restoration activities are also being affected, particularly those involving physical groupings and international travel, some of which may result in increased habitat encroachment, wildlife harvesting or fire, and may therefore precipitate longer-term negative impacts, including those relating to disease pandemics. We conclude that sustainable management of tropical peatlands and their wildlife is important for mitigating impacts of the COVID-19 pandemic, and reducing the potential for future zoonotic EID emergence and severity, thus strengthening arguments for their conservation and restoration. To support this, we list seven specific recommendations relating to sustainable management of tropical peatlands in the context of COVID-19/disease pandemics, plus mitigating the current impacts of COVID-19 and reducing potential future zoonotic EID risk in these localities. Our discussion and many of the issues raised should also be relevant for non-tropical peatland areas and in relation to other (pandemic-related) sudden socio-economic shocks that may occur in future.

Abstract
BACKGROUND Reduction of carbon emissions from peatlands is recognized as an important factor in global climate change mitigation. Within the SE Asia region, areas of deeper peat present the greatest carbon stocks, and therefore the greatest potential for future carbon emissions from degradation and fire. They also support most of the remaining lowland swamp forest and its associated biodiversity. Accurate maps of deep peat are central to providing correct estimates of peat carbon stocks and to facilitating appropriate management interventions. We present a rapid and cost-effective approach to peat thickness mapping in raised peat bogs that applies a model of peat bottom elevation based on field measurements subtracted from a surface elevation model created from airborne LiDAR data. RESULTS In two raised peat bog test areas in Indonesia, we find that field peat thickness measurements correlate well with surface elevation derived from airborne LiDAR based DTMs (R2 0.83-0.88), confirming that the peat bottom is often relatively flat. On this basis, we created a map of extent and depth of deep peat (> 3 m) from a new DTM that covers two-thirds of Sumatran peatlands, applying a flat peat bottom of 0.61 m +MSL determined from the average of 2446 field measurements. A deep peat area coverage of 2.6 Mha or 60.1% of the total peat area in eastern Sumatra is mapped, suggesting that deep peat in this region is more common than shallow peat and its extent was underestimated in earlier maps. The associated deep peat carbon stock range is 9.0-11.5 Pg C in eastern Sumatra alone. CONCLUSION We discuss how the deep peat map may be used to identify priority areas for peat and forest conservation and thereby help prevent major potential future carbon emissions and support the safeguarding of the remaining forest and biodiversity. We propose rapid application of this method to other coastal raised bog peatland areas in SE Asia in support of improved peatland zoning and management. We demonstrate that the upcoming global ICESat-2 and GEDI satellite LiDAR coverage will likely result in a global DTM that, within a few years, will be sufficiently accurate for this application.

Abstract
Peatlands are globally important areas for carbon preservation; although covering only 3% of global land area, they store 30% of total soil carbon. Lowland peat soils can also be very productive for agriculture, but their cultivation requires drainage as most crops are intolerant of root-zone anoxia. This leads to the creation of oxic conditions in which organic matter becomes vulnerable to mineralisation. Given the demand for high quality agricultural land, 40% of the UK's peatlands have been drained for agricultural use. In this study we present the outcomes of a controlled environment experiment conducted on agricultural fen peat to examine possible trade-offs between celery growth (an economically important crop on the agricultural peatlands of eastern England) and emissions of greenhouse gases (carbon dioxide (CO2) and methane (CH4)) at different temperatures (ambient and ambient +5 °C), water table levels (-30 cm, and -50 cm below the surface), and fertiliser use. Raising the water table from -50 cm to -30 cm depressed yields of celery, and at the same time decreased the entire ecosystem CO2 loss by 31%. A 5 °C temperature increase enhanced ecosystem emissions of CO2 by 25% and increased celery dry shoot weight by 23% while not affecting the shoot fresh weight. Fertiliser addition increased both celery yields and soil respiration by 22%. Methane emissions were generally very low and not significantly different from zero. Our results suggest that increasing the water table can lower emissions of greenhouse gases and reduce the rate of peat wastage, but reduces the productivity of celery. If possible, the water table should be raised to -30 cm before and after cultivation, and only decreased during the growing season, as this would reduce the overall greenhouse gas emissions and peat loss, potentially not affecting the production of vegetable crops.

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.
