Abstract
We report the first result of a direct search for a cosmic axion background (CaB)-a relativistic background of axions that is not dark matter-performed with the axion haloscope, the Axion Dark Matter eXperiment (ADMX). Conventional haloscope analyses search for a signal with a narrow bandwidth, as predicted for dark matter, whereas the CaB will be broad. We introduce a novel analysis strategy, which searches for a CaB induced daily modulation in the power measured by the haloscope. Using this, we repurpose data collected to search for dark matter to set a limit on the axion photon coupling of a CaB originating from dark matter cascade decay via a mediator in the 800-995 MHz frequency range. We find that the present sensitivity is limited by fluctuations in the cavity readout as the instrument scans across dark matter masses. Nevertheless, we suggest that these challenges can be surmounted using superconducting qubits as single photon counters, and allow ADMX to operate as a telescope searching for axions emerging from the decay of dark matter. The daily modulation analysis technique we introduce can be deployed for various broadband rf signals, such as other forms of a CaB or even high-frequency gravitational waves.

Background
Chronic Heart Failure (CHF) is associated with a considerable burden of disability. Despite the impact of evidence-based therapies on CHF related deaths and disability, many patients continue to experience persistent symptoms and will die from progressive CHF. This may be exacerbated by the presence of co-morbidities that contribute to both the development and progression of CHF. The identification and management of co-morbidities, such as obstructive sleep apnoea (OSA), may provide an additional strategy for the management of CHF, leading to improved survival, symptoms, and health care cost. OSA remains largely under diagnosed and under treated with a negative impact on the patient and health care systems as complications develop. To bridge this gap and to develop targeted interventions, the identification of possible barriers to, and enablers of, the diagnosis and treatment of OSA in CHF, is essential.
Purpose
To investigate the barriers to, and enablers of, the diagnosis and treatment of OSA from CHF patients’ and clinicians’ perspectives.
Methods
A qualitative study design was utilised to elicit and describe perceived barriers and enablers associated with the diagnosis and treatment of OSA in CHF. CHF patients (n=10) and clinicians (n=20) took part in semi-structured interviews that were analysed using thematic analysis.
Results
Findings from both patients’ and clinicians’ interviews reported barriers and enablers at all stages of the diagnostic pathway. Patient-reported barriers comprised poor recognition of symptoms, lack of understanding, insufficient information provided by health care professionals, poorly tolerated treatment, and poor access to sleep services. Patient enablers were partner-reported symptoms, awareness of others with OSA, confidence in their heart failure clinician, outcome expectancy, and support from a partner and the sleep disorders service.
Clinician-reported barriers were that patients perceived OSA as a low priority compared to their diagnosis of CHF, lack of awareness, knowledge, and skills in the assessment of OSA, variable levels of confidence and low clinical priority of OSA, variable access to sleep services and poor patient uptake and adherence to OSA treatment. Key enablers were perceived outcomes expectancy, education, high confidence, and prompts built into their assessment template.
Conclusion
Findings identified several key barriers and enablers across the OSA diagnostic pathway and associated with both CHF patients and clinicians. Targeted interventions based on the study findings are likely to significantly influence the OSA diagnostic pathway, effective clinical recognition, diagnosis of OSA and treatment of OSA. Development of co-designed and co-produced targeted interventions for clinician upskilling is essential.

Abstract
The needs of romantic partners of people transitioning gender remain neglected within academia and gender services. Following a systematic search, nine studies relating to female partners' experiences were subjected to a thematic metasynthesis. Four themes were generated and entitled Changes in sexual relationship; New roles and responsibilities; Identity and belonging; and Transformation and loss Results are considered in relation to the dominance of the gender-affirmation discourse. Limitations of the review and reviewed studies are highlighted. Clinical implications for couples and partners of people transitioning gender are offered.

Abstract
We report the results from a haloscope search for axion dark matter in the 3.3-4.2 μeV mass range. This search excludes the axion-photon coupling predicted by one of the benchmark models of "invisible" axion dark matter, the Kim-Shifman-Vainshtein-Zakharov model. This sensitivity is achieved using a large-volume cavity, a superconducting magnet, an ultra low noise Josephson parametric amplifier, and sub-Kelvin temperatures. The validity of our detection procedure is ensured by injecting and detecting blind synthetic axion signals.

Abstract
The transcriptional corepressor complex CoREST is one of seven histone deacetylase complexes that regulate the genome through controlling chromatin acetylation. The CoREST complex is unique in containing both histone demethylase and deacetylase enzymes, LSD1 and HDAC1, held together by the RCOR1 scaffold protein. To date, it has been assumed that the enzymes function independently within the complex. Now, we report the assembly of the ternary complex. Using both structural and functional studies, we show that the activity of the two enzymes is closely coupled and that the complex can exist in at least two distinct states with different kinetics. Electron microscopy of the complex reveals a bi-lobed structure with LSD1 and HDAC1 enzymes at opposite ends of the complex. The structure of CoREST in complex with a nucleosome reveals a mode of chromatin engagement that contrasts with previous models. The activities of LSD1 and HDAC1 are closely coupled in the CoREST complex Both LSD1 and HDAC1 exist in two different kinetic states CoREST has a bi-lobed, flexible structure with the two enzymes located at opposite ends CoREST interacts with methylated nucleosomes via LSD1, but not HDAC1 or RCOR1

Abstract
There is increasing interest in the development of multiple sclerosis (MS) biomarkers that reflect central nervous system tissue injury to determine prognosis. We aimed to assess the prognostic value of kinesin superfamily motor protein KIF5A in MS by measuring levels of KIF5A in cerebrospinal fluid (CSF) combined with analysis of single nucleotide polymorphisms (SNPs; rs12368653 and rs703842) located within a MS susceptibility gene locus at chromosome 12q13-14 region. Enzyme-linked immunosorbent assay was used to measure KIF5A in CSF obtained from two independent biobanks comprising non-inflammatory neurological disease controls (NINDC), clinically isolated syndrome (CIS) and MS cases. CSF KIF5A expression was significantly elevated in progressive MS cases compared with NINDCs, CIS and relapsing-remitting MS (RRMS). In addition, levels of KIF5A positively correlated with change in MS disease severity scores (EDSS, MSSS and ARMSSS), in RRMS patients who had documented disease progression at 2-year clinical follow-up. Copies of adenine risk alleles (AG/AA; rs12368653 and rs703842) corresponded with a higher proportion of individuals in relapse at the time of lumbar puncture (LP), higher use of disease-modifying therapies post LP and shorter MS duration. Our study suggests that CSF KIF5A has potential as a predictive biomarker in MS and further studies into the potential prognostic value of analysing MS susceptibility SNPs should be considered.

Abstract
Background:In 2019, EULAR launched the #Time2Work campaign [1] to raise awareness of the impact of rheumatic and musculoskeletal diseases on individuals, society, and the economy. Building on this theme, the Canadian Arthritis Patient Alliance (CAPA) developed a social media campaign and Twitter chat in collaboration with international patient advocates and organizations. The Twitter chat built upon CAPA’s successful development of workplace resources for people living with arthritis [2].Objectives:To deliver an international #ArthritisAtWork social media campaign on Twitter, in support of the #Time2Work campaign.Methods:A one-hour Twitter Chat was held on World Arthritis Day (October 12, 2019) on arthritis in the workplace (#ArthritisAtWork) from 18:00 to 19:00 UTC. The chat was hosted by CAPA and co-hosted by Simon Stones, a patient advocate from the United Kingdom (UK) and CreakyJoints, patient-driven arthritis organization in the United States (US). The Twitter Chat questions were co-developed in advance by the hosts, and blog posts were shared from CAPA’s website. Each host also promoted the Twitter Chat through their websites, newsletters and online communities. A social media analytical tool, Symplur, was used to measure audience engagement using the hashtag #ArthritisAtWork. In addition, pertinent Tweets before, during, and after the chat were obtained. The analysis of themes was undertaken to identify common issues and questions.Results:One hundred and ten users participated in the Twitter chat between 17:20 and 19:20 UTC. Participants included people living with arthritis, researchers, patient organizations, health information outlets and academic institutions. During this period, 565 tweets were shared between participants in Australia, Canada, Ireland, Spain, UK and US. There were 3.352 million Twitter impressions. This represents the number of times a tweet appears to users in either their timeline or search results. Emergent themes of the analysis include:common workplace challenges such as employer attitudes and stigma;effective workplace supports such as prioritizing tasks and requesting workplace accommodations; andareas of improvement such as instituting workplace policies, flexible workplace approaches and education for employees and managers.Conclusion:The social media campaign was successful in reaching a diverse audience and supporting the #Time2Work campaign. Social media tools can provide an important social support for people living with arthritis as they navigate workplace challenges. It also offers a more contemporary platform to engage the international community on issues of common interest. Working together, internationally helps expand reach and reduce barriers in communication. Research can be conducted to measure potential behavior change that leverages digital social support for people living with arthritis.References:[1]EULAR (2019).

Abstract
AIMS Psychological comorbidity, such as depression and/or diabetes-specific emotional distress (DSD), is highly prevalent in people with type 2 diabetes (T2DM) and associated with poorer treatment outcomes. While treatments for depression are well established, interventions specifically designed for DSD are sparse. The aim of this study was to determine interventions that successfully address DSD and HbA1c in people with T2DM. METHODS Seven databases were searched to identify potentially relevant studies. Eligible studies were selected and appraised independently by two reviewers. Multiple meta-analyses and meta-regression analyses were performed to synthesise the data; the primary analyses determined the effect of interventions on DSD, with secondary analyses assessing the effect on HbA1c. RESULTS Thirty-two studies (n = 5206) provided sufficient DSD data, of which 23 (n = 3818) reported data for HbA1c. Meta-analyses demonstrated that interventions significantly reduced DSD (p = 0.034) and HbA1c (p = 0.006) compared to controls, although subgroup meta-analyses and meta-regression to explore specific intervention characteristics that might mediate this effect yielded non-significant findings. CONCLUSIONS The findings demonstrate that existing interventions successfully reduce DSD and HbA1c in people with T2DM. While promising, deductions should be interpreted tentatively, highlighting a stark need for further focused exploration of how best to treat psychological comorbidity in people with T2DM.

Abstract
BACKGROUND Fatigue is a common and disabling symptom in multiple sclerosis (MS) with a variety of direct and indirect influences, but remains poorly understood. Perceived fatigue and cognitive performance fatigability may only be weakly correlated and may have independent predictors. We adopted a multifactorial approach, utilising a measure of concurrent cognitive performance change in order to examine the clinical, psychological, and cognitive factors influencing perceived and cognitive performance fatigability in MS. METHODS Individuals with adult-onset MS were identified from a regional patient database and invited to complete an assessment battery during a home visit. Baseline perceived fatigue was measured using the Modified Fatigue Impact Scale, Fatigue Assessment Instrument, and a Visual Analogue Scale (VAS). The Conners Continuous Performance Test 3 (CCPT3) and VAS were administered before and after our intervention of roughly 2.5 hours of assessment, which represented a period of cognitive effort. The differences in scores formed measures of cognitive performance fatigability and perceived fatigue change, respectively. We examined differences across baseline fatigue, fatigue change and performance change classifications, using regression analysis to uncover predictors of perceived fatigue and performance change. RESULTS The sample comprised 61 participants who were recruited from an existing cohort of MS patients. Positive relationships with depression and emotion-focused coping, and a negative one with sleep, each predicted baseline perceived fatigue with the model explaining 53.5% of variance. Increased perceived fatigue change was not associated with baseline fatigue, cognitive impairment, disease variables or levels of disability, but was linked with higher anxiety, lower self-efficacy and gender. Most CCPT3 performance change variables did not show significant correlations with baseline clinical, psychological, or fatigue variables. However, two variables were predicted by positive relationships with estimated intelligence, whilst a negative relationship with self-efficacy and a positive one with post-intervention fatigue predicted one each. CONCLUSION Fatigue in MS is a multifactorial construct, with perceived fatigue and cognitive performance fatigability largely influenced by indirect psychological and cognitive factors. Future studies need to take these influences into account when developing fatigue assessment tools. Further, targeting influential fatigue drivers such as psychological variables may improve the burden of fatigue and quality of life of people with MS.

Abstract
AIMS Psychological comorbidity, such as depression and/or diabetes-specific emotional distress (diabetes distress), is widespread in people with Type 2 diabetes and is associated with poorer treatment outcomes. Although extensive research into the prevalence of depression has been conducted, the same attention has not been given to diabetes distress. The aim of this systematic review was to determine the overall prevalence of diabetes distress in people with Type 2 diabetes. METHODS Seven databases were searched to identify potentially relevant studies; eligible studies (adult population aged > 18 years with Type 2 diabetes and an outcome measure of diabetes distress) were selected and appraised independently by two reviewers. Multiple fixed- and random-effects meta-analyses were performed to synthesize the data; with primary analyses to determine the overall prevalence of diabetes distress in people with Type 2 diabetes, and secondary meta-analyses and meta-regression to explore the prevalence across different variables. RESULTS Fifty-five studies (n = 36 998) were included in the meta-analysis and demonstrated an overall prevalence of 36% for diabetes distress in people with Type 2 diabetes. Prevalence of diabetes distress was significantly higher in samples with a higher prevalence of comorbid depressive symptoms and a female sample majority. CONCLUSIONS Diabetes distress is a prominent issue in people with Type 2 diabetes that is associated with female gender and comorbid depressive symptoms. It is important to consider the relationship between diabetes distress and depression, and the significant overlap between conditions. Further work is needed to explore psychological comorbidity in Type 2 diabetes to better understand how best to identify and appropriately treat individuals.

Abstract
BACKGROUND Attention-deficit/hyperactivity disorder (ADHD) is a complex highly comorbid disorder, which can have a huge impact on those with ADHD, their family, and the community around them. ADHD is currently managed using pharmacological and nonpharmacological interventions. However, with advances in technology and an increase in the use of mobile apps, managing ADHD can be augmented using apps specifically designed for this population. However, little is known regarding the suitability and usability of currently available apps. OBJECTIVE The aim of this study was to explore the suitability of the top 10 listed apps for children and young people with ADHD and clinicians who work with them. It is hypothesized that mobile apps designed for this population could be more suitably designed for this population. METHODS The top 10 listed apps that are specifically targeted toward children and young people with ADHD in the United Kingdom were identified via the Google Play (n=5) and iTunes store (n=5). Interviews were then undertaken with 5 clinicians who specialize in treating this population and 5 children and young people with ADHD themselves, to explore their opinions of the 10 apps identified and what they believe the key components are for apps to be suitable for this population. RESULTS Five themes emerged from clinician and young people interviews: the accessibility of the technology, the importance of relating to apps, addressing ADHD symptoms and related difficulties, age appropriateness, and app interaction. Three additional themes emerged from the clinician interviews alone: monitoring symptoms, side effects and app effect on relationships, and the impact of common comorbid conditions. The characteristics of the apps did not appear to match well with the views of our sample. CONCLUSIONS These findings suggest that the apps may not be suitable in meeting the complex needs associated with this condition. Further research is required to explore the value of apps for children and young people with ADHD and their families and, in particular, any positive role for apps in the management of ADHD in this age group. A systematic review on how technology can be used to engage this population and how it can be used to help them would be a useful way forward. This could be the platform to begin exploring the use of apps further.

Abstract
Femtosecond magneto-optical measurements detect the formation of a spin-excited state in the vanadium–chromium Prussian blue analogue, which is a molecule-based magnet.
We show that a vanadium–chromium Prussian blue analogue, which is a room-temperature molecule-based magnet, displays a fast magnetic response on a femtosecond timescale that is attributed to the super-exchange interaction between the metal ions. These dynamics are obtained from femtosecond Faraday magneto-optical (MO) measurements, performed at 50 and 300 K. Exciting at the ligand-to-metal charge-transfer (LMCT) band results in the formation of the 2E excited state on the Cr ion via intersystem crossing (ISC) from the 4LMCT state in less than 250 fs. Subsequent vibrational relaxation in the 2E state occurs on a 0.78 ± 0.05 ps timescale at 50 K and 1.1 ± 0.1 ps at 300 K. The MO measurements can detect the formation of the 2E state on the Cr ion from the change in the super-exchange interaction taking place as a result of the corresponding spin flip associated with the formation of the 2E state. These results open up a new avenue to study molecular magnets using a powerful method that is capable of directly probing spin dynamics on a sub-picosecond timescale in thin film environments.

Abstract
INTRODUCTION Transverse myelitis (TM) is an immune-mediated disorder of the spinal cord which causes motor and sensory disturbance and limited recovery in 50% of patients. Standard treatment is steroids, and patients with more severe disease appear to respond to plasma exchange (PLEX). Intravenous immunoglobulin (IVIG) has also been used as an adjunct to steroids, but evidence is lacking. We propose the first randomised control trial in adults and children, to determine the benefit of additional treatment with IVIG. METHODS AND ANALYSIS 170 adults and children aged over 1 year with acute first episode TM or neuromyelitis optica (with myelitis) will be recruited over a 2.5-year period and followed up for 12 months. Participants randomised to the control arm will receive standard therapy of intravenous methylprednisolone (IVMP). The intervention arm will receive the above standard therapy, plus additional IVIG. Primary outcome will be a 2-point improvement on the American Spinal Injury Association (ASIA) Impairment scale at 6 months postrandomisation by blinded assessors. Additional secondary and tertiary outcome measures will be collected: ASIA motor and sensory scales, Kurtzke expanded disability status scale, International Spinal Cord Injury (SCI) Bladder/Bowel Data Set, Client Services Receipt Index, Pediatric Quality of Life Inventory, EQ-5D, SCI Pain and SCI Quality of Life Data Sets. Biological samples will be biobanked for future studies. After 6-months' follow-up of the first 52 recruited patients futility analysis will be carried out. Health economics analysis will be performed to calculate cost-effectiveness. After 6 months' recruitment futility analysis will be performed. ETHICS AND DISSEMINATION Research Ethics Committee Approval was obtained: 14/SC/1329. Current protocol: v3.0 (15/01/2015). Study findings will be published in peer-reviewed journals. TRIAL REGISTRATION NUMBERS This study is registered with EudraCT (REF: 2014-002335-34), Clinicaltrials.gov (REF: NCT02398994) and ISRCTN (REF: 12127581).

Abstract
Huntington's disease (HD) is a neurodegenerative genetic condition for which a predictive genetic test by mutation analysis has been available since 1993. However, whilst revealing the future presence of the disease, testing may have an adverse psychological impact given that the disease is progressive, incurable and ultimately fatal. This review seeks to systematically explore the psychological impact of genetic testing for individuals undergoing pre-symptomatic mutation analysis. Three databases (Medline, PsycInfo and Scopus) were interrogated for studies utilising standardised measures to assess psychological impact following predictive genetic testing for HD. From 100 papers initially identified, eight articles were eligible for inclusion. Psychological impact of predictive genetic testing was not found to be associated with test result. No detrimental effect of predictive genetic testing on non-carriers was found, although the process was not found to be psychologically neutral. Fluctuation in levels of distress was found over time for carriers and non-carriers alike. Methodological weaknesses of published literature were identified, notably the needs of individuals not requesting genetic testing, as well as inadequate support for individuals registering elevated distress and declining post-test follow-up. Further assessment of these vulnerable individuals is warranted to establish the extent and type of future psychological support.

Abstract
AIMS/HYPOTHESIS Human complex metabolic traits are in part regulated by genetic determinants. Here we applied exome sequencing to identify novel associations of coding polymorphisms at minor allele frequencies (MAFs) >1% with common metabolic phenotypes. METHODS The study comprised three stages. We performed medium-depth (8×) whole exome sequencing in 1,000 cases with type 2 diabetes, BMI >27.5 kg/m(2) and hypertension and in 1,000 controls (stage 1). We selected 16,192 polymorphisms nominally associated (p < 0.05) with case-control status, from four selected annotation categories or from loci reported to associate with metabolic traits. These variants were genotyped in 15,989 Danes to search for association with 12 metabolic phenotypes (stage 2). In stage 3, polymorphisms showing potential associations were genotyped in a further 63,896 Europeans. RESULTS Exome sequencing identified 70,182 polymorphisms with MAF >1%. In stage 2 we identified 51 potential associations with one or more of eight metabolic phenotypes covered by 45 unique polymorphisms. In meta-analyses of stage 2 and stage 3 results, we demonstrated robust associations for coding polymorphisms in CD300LG (fasting HDL-cholesterol: MAF 3.5%, p = 8.5 × 10(-14)), COBLL1 (type 2 diabetes: MAF 12.5%, OR 0.88, p = 1.2 × 10(-11)) and MACF1 (type 2 diabetes: MAF 23.4%, OR 1.10, p = 8.2 × 10(-10)). CONCLUSIONS/INTERPRETATION We applied exome sequencing as a basis for finding genetic determinants of metabolic traits and show the existence of low-frequency and common coding polymorphisms with impact on common metabolic traits. Based on our study, coding polymorphisms with MAF above 1% do not seem to have particularly high effect sizes on the measured metabolic traits.

Abstract
Carbonic anhydrase IX (CA IX) is a hypoxia-regulated enzyme, overexpressed in many types of human cancer. CA IX is involved in pH homeostasis, contributing to extracellular acidification and tumourigenesis. Acidification of the extracellular milieu can impact upon cellular uptake of chemotherapeutic drugs by favouring weak acids (e.g. melphalan), but limiting access of weak bases (e.g. doxorubicin). We investigated whether alterations of CA IX activity affected anti-cancer drug uptake and toxicity. CA inhibitor acetazolamide (AZM) enhanced doxorubicin toxicity but reduced melphalan toxicity in cell lines that highly expressed CA IX under anoxic conditions (HT29 and MDA435 CA9/18). The toxicity changes reflected modification of passive drug uptake. AZM did not alter toxicity or uptake in cells with low CA IX activity (HCT116 and MDA435 EV1). AZM lowered intracellular pH in HT29 and MDA435 CA9/18 cells under anoxic conditions. CA IX activity has chemomodulatory properties and is an attractive target for anti-cancer therapy.

Abstract
'It's Your Move!' was a 3-year intervention study implemented in secondary schools in Australia as part of the Pacific Obesity Prevention In Communities Project. This paper reports the outcome results of anthropometric indices and relevant obesity-related behaviours. The interventions focused on building the capacity of families, schools and communities to promote healthy eating and physical activity. Baseline response rates and follow-up rates were 53% and 69% respectively for the intervention group (n=5 schools) and 47% and 66% respectively for the comparison group (n=7 schools). Statistically significant relative reductions in the intervention versus comparison group were observed: weight (-0.74 kg, P < 0.04), and standardized body mass index (-0.07, P<0.03), and non-significant reductions in prevalence of overweight and obesity (0.75 odds ratio, P=0.12) and body mass index (-0.22, P=0.06). Obesity-related behavioural variables showed mixed results with no pattern of positive intervention outcomes. In conclusion, this is the first study to show that long-term, community-based interventions using a capacity-building approach can prevent unhealthy weight gain in adolescents. Obesity prevention efforts in this important transitional stage of life can be successful and these findings need to be translated to scale for a national effort to reverse the epidemic in children and adolescents.

Abstract
BACKGROUND AND PURPOSE Neuromyeltis optica (NMO) is a neuroinflammatory disorder considered rare in Caucasian populations. However, accurate population-based epidemiological data for NMO and NMO spectrum disorder (NMO-SD) from Western populations employing validated diagnostic criteria remain limited. We sought therefore to estimate the prevalence and clinical features of NMO in a north European Caucasian population in South East Wales. METHODS Patients were identified by a comprehensive, multistage ascertainment strategy employing a regional neuroinflammatory disease register, hospital diagnostic databases personal physician referrals and regional requests for anti-aquaporin-4 antibodies (anti-AQP4). RESULTS Fourteen Caucasian patients (11 patients with NMO and three with NMO-SD) were identified in a population of 712,572 (19.6/million; 95% CIs: 12.2-29.7). There was an excess of females (female:male 12:2), 11/14 were anti-AQP4 positive and 5/14 had disease onset under the age of 20 years. CONCLUSION This study suggests that NMO and related spectrum disorders are at least as frequent in Northern European populations as in non-Caucasian populations and that the demographic profile of prevalent patients differs from clinic-based cohorts.

Abstract
Genetic factors are likely to affect individual cancer risk, but few quantitative estimates of heritability are available. Public health radiation protection policies do not in general take this potentially important source of variation in risk into account. Two surrogate cellular assays that relate to cancer susceptibility have been developed to gain an insight into the role of genetics in determining individual variation in radiosensitivity. These flow cytometric assays for apoptosis induction and cell cycle delay following radiation are sufficiently sensitive to distinguish lymphocytes from a healthy donor population from those of a sample of obligate carriers of ATM mutations (P = 0.01 and P = 0.02, respectively). Analysis of 54 unselected twin pairs (38 dizygotic, 16 monozygotic) indicated much greater intrapair correlation in response in monozygotic than in dizygotic pairs. Structural equation modelling indicated that models including unique environmental factors only fitted the data less well than those incorporating two or more of additive genetic factors, common environmental factors and unique environmental factors. A model incorporating additive genetic factors and unique environmental factors yielded estimates of heritability for the two traits of 68% (95% CI 40-82%, cell cycle) and 59% (95% CI 22-79%, apoptosis). Thus, these data suggest that genetic factors contribute significantly to human variation in these two measures of radiosensitivity that relate to cancer susceptibility.

Abstract
OBJECTIVES To assess the psychological morbidity and illness beliefs in newly referred patients with chest pain, and to compare the psychological morbidity of patients with pain of cardiac origin with that of patients with pain of non-cardiac origin. DESIGN Longitudinal cohort study. SETTING Rapid Access Chest Pain Clinic in a tertiary referral centre in Leicester, United Kingdom. PARTICIPANTS 246 patients with acute, undifferentiated, chest pain followed up 1 week and 2 months subsequent to clinic attendance. MAIN OUTCOME MEASURES Levels of affective disturbance, health anxiety and illness perception. RESULTS Levels of anxiety before clinic attendance exceeded community norms but did not differentiate the two groups. However, after clinic attendance levels of anxiety for those with a non-cardiac diagnosis significantly exceeded those of patients whose pain was of cardiac origin and remained above community norms 2 months hence. Non-cardiac patients viewed their condition as significantly less controllable and less understandable than those whose pain was cardiac in origin. Levels of depression for those with cardiac pain also significantly increased to above community norms after clinic attendance. CONCLUSIONS Clinical levels of psychological morbidity are evident in the immediate and long-term aftermath of a visit to a Rapid Access Chest Pain Clinic, despite early access and provision of reassurance. More structured interventions appear necessary to deal with both distress and illness beliefs that may influence future healthcare use.

Abstract
We report on a giant basilar tip aneurysm in a 48-year-old woman that could not be clipped despite temporary occlusion of the basilar trunk. Adenosine induced cardiac asystole reduced the aneurysm's wall tension and coupled with increased exposure resulting from brain relaxation allowed for the aneurysm to be satisfactorily occluded via an extended right pterional craniotomy. In difficult vascular cases, adenosine induced cardiac standstill is a useful technique which may allow for technical success when other methods such as temporary clipping fail. It acts to both reduce aneurysm wall tension and increase operative exposure by reducing vascular, and hence brain volume.

Abstract
AIMS To examine psychological adjustment and changes in the activities of daily living in relation to visual loss in diabetes. METHODS This was an incident cohort, longitudinal, observational study contrasting the adjustment of individuals with visual loss associated with diabetes and those whose visual loss arose from other conditions; in the year subsequent to registration for blindness and 12 months later, 124 individuals participated in the study (51 with diabetes and 73 without). Participants provided demographic and biomedical information, and completed the Brief COPE, Hospital Anxiety and Depression Scale, SF-36, Instrumental Activities of Daily Living scale and Social Avoidance and Distress Scale via interview. People with diabetes were compared with those without. RESULTS Both diabetic and non-diabetic groups showed elevated and comparable levels of psychological morbidity, sustained over time. Significant differences in functional adjustment were found at initial interview: people with diabetes having more problems coping but these were no longer present 1 year later. CONCLUSIONS There was a significant and enduring elevation of anxiety and depression in those who were newly registered blind or visually handicapped. Taking these findings into account, psychological assessment should be developed for all those experiencing visual loss.

Abstract
We describe cisRED, a database for conserved regulatory elements that are identified and ranked by a genome-scale computational system (www.cisred.org). The database and high-throughput predictive pipeline are designed to address diverse target genomes in the context of rapidly evolving data resources and tools. Motifs are predicted in promoter regions using multiple discovery methods applied to sequence sets that include corresponding sequence regions from vertebrates. We estimate motif significance by applying discovery and post-processing methods to randomized sequence sets that are adaptively derived from target sequence sets, retain motifs with p-values below a threshold and identify groups of similar motifs and co-occurring motif patterns. The database offers information on atomic motifs, motif groups and patterns. It is web-accessible, and can be queried directly, downloaded or installed locally.

Abstract
The guanidinium acid-phenol method of RNA extraction is relatively fast (4 h) and is useful for the processing of large numbers of samples, without the need for ultracentrifugation. This protocol produces total RNA that includes ribosomal, transfer, and messenger RNA. This high-quality RNA is suitable for Northern blot analysis, dot-blot hybridization, poly (A) RNA selection, in vitro translation, cDNA library construction, reverse transcriptase-polymerase chain reaction, ribonuclease protection assay, and primer extension experiments.

Abstract
BACKGROUND Strategies to implement change in health professional performance have variable impact. A potential explanation is that the barriers to implementation are different in different settings and at different times. Change may be more likely if the strategies were specifically chosen to address the identified barriers. OBJECTIVES To assess the effectiveness of strategies tailored to address specific, identified barriers to change in professional performance. SEARCH STRATEGY We searched the Cochrane Effective Practice and Organisation of Care Group (EPOC) specialised register and pending files until end of December 2002. English language articles only were included. SELECTION CRITERIA Randomised controlled trials (RCTs) that reported objectively measured professional practice or health care outcomes in which at least one group received an intervention designed (or tailored) to address prospectively identified barriers to change. DATA COLLECTION AND ANALYSIS Two reviewers independently extracted data and assessed quality. We also contacted study authors to obtain any missing information. Quantitative and qualitative analyses were undertaken. MAIN RESULTS We included 15 studies. For Comparison 1 (an intervention tailored to address identified barriers to change compared to no intervention or an intervention(s) not tailored to the barriers), there was no consistency in the results and the effect sizes varied both across and within studies.A meta-regression of a subset of the included studies, using a classical approach estimated a combined OR of 2.18 (95% CI: 1.09, 4.34), p = 0.026 in favour of tailored interventions. However, when a Bayesian approach was taken, meta-regression gave a combined OR of 2.27 (95% Credible Interval: 0.92, 4.75), which was not statistically significant. AUTHORS' CONCLUSIONS Interventions tailored to prospectively identify barriers may improve care and patient outcomes. However, from the studies included in this review, we were unable to determine whether the barriers were valid, which were the most important barriers, whether all barriers were identified and if they had been addressed by the intervention chosen. Based on the evidence presented in this review, the effectiveness of tailored interventions remains uncertain and more rigorous trials (including process evaluations) are needed. Further research needs to address explicitly the questions of identifying and addressing barriers.

Abstract
Carbonic anhydrase IX (CAIX) is a membrane-associated carbonic anhydrase (CA), strongly induced by hypoxia. CAIX is overexpressed in a variety of tumor types and associated with increased metastasis and poor prognosis. An inhibitor of CAs, acetazolamide has been reported to inhibit invasion. We used RNA interference (RNAi) to examine the function of CAIX in MDA468 and MDA231 breast carcinoma cells, which express high levels of CAIX under hypoxia. Hypoxia-induced CA activity was completely blocked by specific RNAi (P < 0.01). RNAi-treated cells showed growth delay in dense monolayer culture and a 50% reduction in clonogenic survival under hypoxia. In the MDA468 cells, there was no effect of RNAi treatment on invasion. In a cell line that did not induce CAIX under hypoxia, RT112, we found no effect on the ability of cells transfected with CAIX to invade or migrate. Thus, CAIX plays an important role in the growth and survival of tumor cells under normoxia and hypoxia, making it a potential target for cancer therapy, but is not involved in invasion.

Abstract
AIM The benefit of anti-reflux surgery for gastro-oesophageal reflux (GOR) in early infancy is uncertain. The aim of this study was to assess the value of Nissen fundoplication in a group of infants with severe GOR. METHODS 10 infants underwent Nissen fundoplication for gastro-oesophageal reflux following a failure of medical management. All had suffered life-threatening respiratory episodes as a consequence of gastro-oesophageal reflux, and were neonatal intensive care-dependent. Median (range) birth weight was 1.26 kg (0.48-3.8 kg), gestation 30 weeks (25-38 weeks); at surgery, weight was 3.25 kg (2.5-6.1 kg) at a corrected age of 11.5 weeks (term-22) weeks. For each infant, the success of enteral feeding and the level of support required pre- and post-operatively was compared, and where appropriate, the facilitation of palliative feeding was assessed. Median follow-up was 14 (3-36) months. RESULTS No infant suffered intra-operative morbidity or mortality. One infant died within 1 month of surgery from a collapse unrelated to surgery. Eight of nine surviving infants were discharged from intensive care following extubation and the establishment of enteral feeding. One patient died of severe bronchopulmonary dysplasia 3 months post-surgery. One infant developed a gastrostomy site infection, and two required gastrostomy tube replacement within 6 months of surgery. All were thriving at follow-up. Two infants with a congenital myopathy died as a result of their muscle disease at 9 and 11 months post-operatively. CONCLUSIONS Nissen fundoplication is a feasible, effective and safe operation in severe gastro-oesophageal reflux unresponsive to medical treatment in term and pre-term infants. It has an additional important role in facilitating safe palliative enteral feeding in infants with a diagnosis incompatible with survival into adulthood.
