RESUMEN
PURPOSE: The primary aim of this study was to investigate the health behaviour status of teenage and young adult (TYA) cancer patients and survivors; the secondary aim was to determine if TYA cancer patients and survivors health behaviour differs to general population controls. METHODS: Two hundred sixty-seven young people with cancer (n =83 cancer patients receiving active treatment: n =174 cancer survivors, 57.1% >1 year since treatment completion) and 321 controls completed a health and lifestyle questionnaire which included validated measures of physical activity (PA) (Godin Leisure Time Exercise Questionnaire), diet (Dietary Instrument for Nutrition Education, DINE), smoking status, and alcohol consumption (AUDIT-C). RESULTS: General population controls and cancer survivors were more likely to meet current (PA) recommendations (p <0.001) than TYA cancer patients undergoing treatment (54.8% vs 52.3% vs 30.1%, respectively). Less than 40% of young people with cancer and controls met fat intake, sugar intake, fibre intake or current fruit and vegetable recommendations. TYA cancer survivors were more likely to report binge drinking than controls (OR=3.26, 95% CI 2.12-5.02, p <0.001). Very few young people with in the study were current smokers. The majority of TYA cancer patients and survivors reported a desire to make positive changes to their health behaviour. CONCLUSION: Consideration should be given to whether existing health behaviour change interventions which have demonstrated positive effects among the general TYA population could be adapted for young people with cancer.

The feedback between fluid migration and rock deformation in mid-crustal shear zones is acknowledged as being critical for earthquake nucleation, the initiation of subduction zones and the formation of mineral deposits. The importance of this poorly understood feedback is further highlighted by evidence for shear-zone-controlled advective flow of fluids in the ductile lower crust and the recognition that deformation-induced grain-scale porosity is a key to large-scale geodynamics. Fluid migration in the middle crust cannot be explained in terms of classical concepts. The environment is considered too hot for a dynamic fracture-sustained permeability as in the upper crust, and fluid pathways are generally too deformed to be controlled by equilibrium wetting angles that apply to hotter, deeper environments. Here we present evidence that mechanical and chemical potentials control a syndeformational porosity generation in mid-crustal shear zones. High-resolution synchrotron X-ray tomography and scanning electron microscopy observations allow us to formulate a model for fluid migration in shear zones where a permeable porosity is dynamically created by viscous grain-boundary sliding, creep cavitation, dissolution and precipitation. We propose that syndeformational fluid migration in our 'granular fluid pump' model is a self-sustained process controlled by the explicit role of the rate of entropy production of the underlying irreversible mechanical and chemical microprocesses. The model explains fluid transfer through the middle crust, where strain localization in the creep regime is required for plate tectonics, the formation of giant ore deposits, mantle degassing and earthquake nucleation. Our findings provide a key component for the understanding of creep instabilities in the middle crust.
RESUMEN
While urban-grown vegetables could help combat future food insecurity, the elevated levels of toxic metals in urban soils need to be met with measures that minimise transfer to crops. This study firstly examines soil/dust particle inclusion in leafy vegetables and its contribution to vegetable metals (As, Ba, Cd, Co, Cr, Cu, Ni, Pb, Sb, and Zn), using vegetable, soil and dust data from an open-field urban farm in southeastern Sweden. Titanium concentrations were used to assess soil/dust adherence. Results showed that vegetables contained 0.05-1.3 wt% of adhering particles (AP) even after washing. With 0.5 % AP, an adult with an average intake of vegetables could ingest approximately 100 mg of particles per day, highlighting leafy vegetables as a major route for soil/dust ingestion. The presence of adhering particles also significantly contributed to the vegetable concentrations of As (9-20 %), Co (17-20 %), Pb (25-29 %), and Cr (33-34 %). Secondly, data from an indoor experiment was used to characterise root metal uptake from 20 urban soils from Sweden, Denmark, Spain, the UK, and the Czech Republic. Combining particle adherence and root uptake data, vegetable metal concentrations were calculated for the 20 urban soils to represent hypothetical field scenarios for these. Subsequently, average daily doses were assessed for vegetable consumers (adults and 3-6 year old children), distinguishing between doses from adhering particles and root uptake. Risks were evaluated from hazard quotients (HQs; average daily doses/tolerable intakes). Lead was found to pose the greatest risk, where particle ingestion often resulted in HQs > 1 across all assessed scenarios. In summary, since washing was shown to remove only a portion of adhering metal-laden soil/dust particles from leafy vegetation, farmers and urban planners need to consider that measures to limit particle deposition are equally important as cultivating in uncontaminated soil.

Technology-critical elements (TCEs) include most rare earth elements (REEs), the platinum group elements (PGEs), and Ga, Ge, In, Nb, Ta, Te, and Tl. Despite increasing recognition of their prolific release into the environment, their soil to plant transfer remains largely unknown. This paper provides an approximation of the potential for plant uptake by calculating bioconcentration factors (BCFs), defined as the concentration in edible vegetable tissues relative to that in cultivation soil. Here data were obtained from an indoor cultivation experiment growing lettuce, chard, and carrot on 22 different European urban soils. Values of BCFs were determined from concentrations of TCEs in vegetable samples after digestion with concentrated HNO3, and from concentrations in soil determined after 1) Aqua Regia digestion and, 2) diluted (0.1 M) HNO3 leaching. For comparison, BCFs were also determined for 5 traditional metal contaminants (TMCs; As, Cd, Cu, Pb, and Zn). The main conclusions of the study were that: 1)BCF values for the REEs were consistently low in the studied vegetables;2)the BCFs for Ga and Nb were low as well;3) the BCFs for Tl were high relative to the other measured TCEs and the traditional metal contaminants; and 4) mean BCF values for the investigated TCEs were generally highest in chard and lowest in carrot. These findings provide initial evidence that there are likely to be real and present soil-plant transfer of TCEs, especially in the case of Tl. Improvements in analytical methods and detection limits will allow this to be further investigated in a wider variety of edible plants so that a risk profile may be developed.

Intact rabbit immunoglobulin G molecules (IgGs) and their papain or pepsin fragments were radio-iodinated and injected into HeLa cells. Whole IgGs, Fab2, and Fc fragments were degraded with half-lives of 60-90 h, whereas half-lives of Fab fragments were 110 h. These results indicate that proteolytic cleavage in the hinge region of the IgG molecule is not the rate-limiting step in its intracellular degradation. The hingeless human myeloma protein, Mcg, was degraded at the same rate as bulk human IgG, providing further evidence that the proteolytically susceptible hinge region is not important for intracellular degradation of IgG molecules. SDS acrylamide gel analysis of injected rabbit IgG molecules revealed that heavy and light chains were degraded at the same rate. Injected rabbit IgGs and rabbit IgG fragments were also examined on isoelectric focusing gels. Fab, Fab2, and Fc fragments were degraded without any correlation with respect to isoelectric point. Positively charged rabbit IgGs disappeared more rapidly than their negative counterparts, contrary to the trend reported for normal intracellular proteins. The isoelectric points of two mouse monoclonal antibodies were essentially unchanged after injection into HeLa cells, suggesting that the altered isoelectric profile observed for intact rabbit IgG resulted from degradation and not protein modification. The intracellular distributions of IgG fragments and intact rabbit IgG molecules were determined by autoradiography of thin sections through injected cells. Intact IgG molecules were excluded from HeLa nuclei whereas both Fab and Fc fragments readily entered them. Thus, for some proteins, entry into the nuclear compartment is determined primarily by size.

PLAIN ENGLISH SUMMARY: This paper describes the methods that were used to develop a health behaviour intervention specifically for teenage and young adult cancer survivors (TYACS). The program of work, carried out in partnership with CLIC Sargent (a UK based cancer charity for children and young people) was guided by The Behaviour Change Intervention Design Process. A systematic review of existing intervention studies was carried out and TYACS were surveyed on their interest in receiving health behaviour information and their preference regarding the format, delivery and timing of such information. Health professionals were also surveyed to gather their views on how health behaviour information would be best delivered to young people with cancer. The results of these studies informed the development of a collection of health behaviour change intervention resources containing comprehensive lifestyle information and behaviour change support tools. TYACS and TYA health professionals were invited to review and provide feedback on the relevance, appeal and usability of the resources. It is hoped that by involving TYACS and TYA representatives at every stage of intervention development the problem of low uptake and adherence commonly encountered during intervention piloting will be prevented. ABSTRACT: Background Teenage and Young Adult Cancer Survivors (TYACS) are advised to adopt a healthy lifestyle in order to reduce the impact of cancer and its treatments upon their long-term health. However, at present there are no interventions available in the UK to support TYACS to lead a healthy lifestyle. To inform the development of a lifestyle intervention for TYACS a partnership was set up between academic behavioural scientists and CLIC Sargent, a cancer charity which supports children and young people. Methods A series of studies to understand patient and professionals needs and perspectives regarding health behaviour change were carried out. TYACS were surveyed to gather data on their current health behaviour status; interest in, and experience of receiving, lifestyle advice; and preference regarding the type, format, and delivery of a lifestyle intervention. Health care professionals were surveyed simultaneously to gather their views on how best to promote health behaviour change to TYACS. In this paper we summarise key findings from the development work, the resulting lifestyle intervention, and new data from a preliminary evaluation study exploring TYACS and TYA health professionals' views on the relevance, appeal and usability of the intervention resources. Results A collection of health behaviour change intervention resources containing lifestyle information and behaviour change support tools were developed. These intervention resources were well received by TYACS and health professionals with the majority rating the information as high quality, helpful and relevant. Over 80% of TYACS reported they would find the support tools 'very appealing' or 'quite appealing'. TYACS and health professionals provided feedback on how the resources could be improved including commenting that more personalized or tailored health behaviour information would be beneficial. Discussion and conclusion It is hoped that by involving TYACS and TYA representatives at every stage of intervention development,and carrying out a preliminary evaluation of the intervention resources, the problem of low uptake and adherence commonly encountered during formal intervention piloting and evaluation will be prevented.

RESUMEN
Here we examine the molecular basis for the known preferential expression of rabbit aldehyde dehydrogenase class 1 (ALDH1A1) in the cornea. The rabbit Aldh1a1 promoter-firefly luciferase reporter transgene (-3519 to +43) was expressed preferentially in corneal cells in transfection tests and in transgenic mice, with an expression pattern resembling that of rabbit Aldh1a1. The 5' flanking region of the rabbit Aldh1a1 gene resembled that in the human gene (60.2%) more closely than that in the mouse (46%) or rat (51.5%) genes. We detected three xenobiotic response elements (XREs) and one E-box consensus sequence in the rabbit Aldh1a1 upstream region; these elements are prevalent in other highly expressed corneal genes and can mediate stimulation by dioxin and repression by CoCl(2), which simulates hypoxia. The rabbit Aldh1a1 promoter was stimulated fourfold by dioxin in human hepatoma cells and repressed threefold by CoCl(2) treatment in rabbit corneal stromal and epithelial cells. Cotransfection, mutagenesis, and gel retardation experiments implicated the hypoxia-inducible factor 3alpha/aryl hydrocarbon nuclear translocator heterodimer for Aldh1a1 promoter activation via the XREs and stimulated by retinoic acid protein 13 for promoter repression via the E-box. These experiments suggest that XREs, E-boxes, and PAS domain/basic helix-loop-helix transcription factors (bHLH-PAS) contribute to preferential rabbit Aldh1a1 promoter activity in the cornea, implicating hypoxia-related pathways.

Trials with second generation CD19 chimeric antigen receptors (CAR) T-cells report unprecedented responses but are associated with risk of cytokine release syndrome (CRS). Instead, we studied the use of donor Epstein-Barr virus-specific T-cells (EBV CTL) transduced with a first generation CD19CAR, relying on the endogenous T-cell receptor for proliferation. We conducted a multi-center phase I/II study of donor CD19CAR transduced EBV CTL in pediatric acute lymphoblastic leukaemia (ALL). Patients were eligible pre-emptively if they developed molecular relapse (>5 × 10-4) post first stem cell transplant (SCT), or prophylactically post second SCT. An initial cohort showed poor expansion/persistence. We therefore investigated EBV-directed vaccination to enhance expansion/persistence. Eleven patients were treated. No CRS, neurotoxicity or graft versus host disease (GVHD) was observed. At 1 month, 5 patients were in CR (4 continuing, 1 de novo), 1 PR, 3 had stable disease and 3 no response. At a median follow-up of 12 months, 10 of 11 have relapsed, 2 are alive with disease and 1 alive in CR 3 years. Although CD19CAR CTL expansion was poor, persistence was enhanced by vaccination. Median persistence was 0 (range: 0-28) days without vaccination compared to 56 (range: 0-221) days with vaccination (P=0.06). This study demonstrates the feasibility of multi-center studies of CAR T cell therapy and the potential for enhancing persistence with vaccination.

The aim of this study was to retrospectively define those patients with unequivocal primary bone lymphoma presenting to the Sheffield Lymphoma Group and document patient and tumour characteristics and management strategies, and correlate these with survival. Thirty-seven patients were documented from a total of 3148 cases of non-Hodgkin's lymphoma seen over 34 years. There were 17 males and 20 females, with a mean age of 55.4 years (range, 27-78). Pain was the most commonly presented symptom (67.5%), and the pelvis was the most frequently presented site (21.3%). Grade 2 and diffuse large B cell lymphoma comprised the majority of histologies (78.7% and 70.3%, respectively). Treatment was most often with radiotherapy alone (41.8%) or combined with CHOP-like chemotherapy (37.9%). The overall response rate was 56.7%, and 5- and 10-year survival rates were 64.5% and 49.6%, respectively. Univariate analysis showed an age of <60 years and complete response to be favourable prognostic factors. There was a trend toward better survival with combined modality therapy involving CHOP-like chemotherapy. Bone lymphoma has a better survival than other extranodal lymphomas. Younger age and complete response are favourable predictive factors. Combined modality treatment is likely to be the treatment of choice but this remains to be confirmed in large prospective multicentre studies.

The Caenorhabditis elegans T20H4.4 open reading frame (GenBank accession no. U00037) predicted by Genefinder encodes a 367 amino acid protein that is 32-35% identical to the C-terminal domain of adenosine deaminases that act on RNA. We show that T20H4.4 cDNAs (GenBank accession no. AF051275) encode a larger 495 amino acid protein that is extended at its N-terminus to include a single double-stranded RNA-binding motif, and that T20H4.4 occupies the second position in a six-gene operon (5'-T20H4.5, T20H4.4, R151.8A, R151.8B, R151.7, R151.6-3'). Ten different spliced-leader (SL) sequences were found attached to T20H4.4 mRNAs, including SL1, SL2 and eight SL2-like leaders that include two new variants. Characterization of cDNAs derived from all six genes confirmed the essential features of C.elegans operons: intercistronic distances in the range of 104-257 nt between the upstream polyadenylation sites and the downstream trans -splice sites; SL2, or SL2-like leaders, attached to the downstream mRNAs. Polycistronic mRNA fragments revealed a 5'-untranslated region (5'-UTR) >705 nt. The 5'-UTR is removed in mature mRNAs from the first gene (T20H4.5) and replaced primarily by SL1, and to a lesser extent by SL2. Our study provides new information regarding operons and how they are processed.

Heavy metal(loid) rich ash (≤10,000 mg kg-1 total As, Cr, Cu and Zn) originating from the combustion of contaminated wood was subjected to several experimental procedures involving its incorporation into an upland pasture soil. Ash was added to soil that had been prior amended with local cattle manure, replicating practices employed at the farm scale. Metal(loid) concentrations were measured in soil pore water and ryegrass grown on soil/manure plus ash mixtures (0.1-3.0% vol. ash) in a pot experiment; toxicity evaluation was performed on the same pore water samples by means of a bacterial luminescence biosensor assay. Thereafter a sequential extraction procedure was carried out on selected soil, manure and ash mixtures to elucidate the geochemical association of ash derived metal(loid)s with soil constituents. Predictive modelling was applied to selected data from the pot experiment to determine the risk of transfer of As to meat and milk products in cattle grazing pasture amended with ash. The inclusion of manure to soils receiving ash reduced phyto-toxicity and increased ryegrass biomass yields, compared to soil with ash, but without manure. Elevated As and Cu concentrations in pore water and ryegrass tissue resulting from ash additions were reduced furthest by the inclusion of manure due to an increase in their geochemical association with organic matter. Zinc was the only measured metal(loid) to remain uniformly soluble and bioavailable regardless of the addition of ash and manure. Risk modelling on pot experimental data highlighted that an ash addition of >1% (vol.) to this pasture soil could result in As concentrations in milk and meat products exceeding acceptable limits. The results of this study therefore suggest that even singular low doses of ash applied to soil increase the risk of leaching of metal(loid)s and intensify the risk of As transfer in the food chain.

The use of the National Institute of Mental Health Diagnostic Interview Schedule (DIS) to elicit DSM-III-defined mental disorders among Hispanic respondents in the Los Angeles site of the Epidemiologic Catchment Area project required development of a Spanish translation of the instrument that would be understood readily by persons of Mexican, Puerto Rican, and Cuban origin. The translation was carried out using back translation, bilingual test respondents, a bilingual translation staff, an extensive committee of experienced bilingual clinicians as translation consultants, and revision following clinical evaluation. A study of its reliability and comparison with clinical diagnoses obtained with Spanish-speaking psychiatric outpatients indicated satisfactory equivalence of the Spanish DIS to the English version. Early international use of the Spanish DIS promises new data on the cross-cultural validity and prevalence rates of DSM-III-diagnosed disorders.

The National Institute of Mental Health Diagnostic Interview Schedule (DIS) was translated into Spanish. The reliability of the Spanish instrument, its equivalence to the English version, and its agreement with clinical diagnoses were examined in a study of 90 bilingual (English-and Spanish-speaking) and 61 monolingual (Spanish-speaking only) patients from a community mental health center. The study design involved two independent DIS administrations and one independent clinical evaluation of each subject.

The National Institute of Mental Health multisite Epidemiologic Catchment Area (ECA) program is described in the context of four previous psychiatric epidemiologic surveys that included a combined total of 4,000 subjects from Stirling County, the Baltimore Morbidity Study, Midtown Manhattan, and the New Haven third-wave survey. The ECA program is distinguished by its sample size of at least 3,500 subjects per site (about 20,000 total); the focus on Diagnostic Interview Schedule--defined DSM-III mental disorders; the one-year reinterview-based longitudinal design to obtain incidence and service use data; the linkage of epidemiologic and health service use data; and the replication of design and method in multiple sites. Demographic characteristics of community and sample populations are provided for New Haven, Conn, Baltimore, and St Louis.

Utilization of general medical and mental health services by respondents in the Los Angeles Epidemiologic Catchment Area (ECA) site was compared with that in three ECA sites studied previously (New Haven, Conn, Baltimore, and St Louis). Within the Los Angeles sample, Mexican-American patterns of utilization were compared with those for non-Hispanic whites. Los Angeles respondents were less likely than those at other ECA sites to make ambulatory health care visits and to be hospitalized for physical or mental health reasons. Mexican Americans were less likely than non-Hispanic whites to report ambulatory health care but were as likely to have been hospitalized. Six percent of Los Angeles respondents reported a recent mental-health-care visit as compared with 6% to 7% of respondents at the other ECA sites. However, among respondents with Diagnostic Interview Schedule DSM-III disorders diagnosed within the six months prior to the interview, a lower proportion made a mental health visit in Los Angeles (14%) compared with the other sites (16% to 20%). Of those who made a mental-health-care visit, Los Angeles respondents with a recently diagnosed disorder were more likely than comparable respondents at the other ECA sites to visit a mental health specialist rather than a general medical care provider. Mexican Americans with a recently diagnosed mental disorder were only half as likely as non-Hispanic whites (11% vs 22%, respectively) to have made a mental health visit. However, when Mexican Americans with Diagnostic Interview Schedule/DSM-III did make a mental health visit, they were as likely as non-Hispanic whites to see a mental health specialist.

To determine if Vietnam theater veterans were more likely than controls to have a specific psychiatric disorder other than posttraumatic stress disorder, the rates of specific psychiatric disorders were estimated using the Diagnostic Interview Schedule for national samples of veterans who served in Vietnam, other veterans of the Vietnam era, and matched civilian controls. Overall, there were few differences in rates of disorder between theater and other veterans; there were somewhat more differences between theater veterans and civilians. There were striking differences, however, in rates for most disorders, both lifetime and current, between male theater veterans with high levels of exposure to war zone stress and other male veterans or civilians. Female veterans exposed to high levels of war zone stress also had higher rates than other female respondents for several disorders.

The current prevalence of DSM-III psychiatric disorders was assessed using the Diagnostic Interview Schedule (DIS) as part of a Los Angeles household population survey. The Los Angeles prevalence estimates were compared with sex- and age-adjusted estimates from four other US field sites, all of which were part of the Epidemiologic Catchment Area (ECA) program. Overall, few significant differences in household population rates were found between Los Angeles and the other ECA sites. Within the Los Angeles household sample, the current prevalence of disorder among Mexican Americans was compared with that among non-Hispanic whites. Non-Hispanic whites had higher rates of drug abuse/dependence than Mexican Americans; the rates among non-Hispanic whites in Los Angeles were also higher than those found at other ECA sites. Mexican Americans displayed higher rates of severe cognitive impairment, a finding that likely reflects ethnic and educational bias in the measurement of cognitive impairment. Another ethnic difference was found only for one specific age and sex group: Mexican-American women 40 years of age or older had strikingly high rates of phobia.

The lifetime prevalence of specific DSM-III-defined psychiatric disorders among 1243 Mexican-American and 1309 non-Hispanic white residents of two Los Angeles communities is reported from the Los Angeles site of the Epidemiologic Catchment Area (ECA) research study. Results from household interviews in response to the National Institute of Mental Health Diagnostic Interview Schedule revealed overall rates of disorders for the total Los Angeles sample and ethnic subsamples that were similar to rates reported from the initial three ECA sites. Non-Hispanic whites reported far more drug abuse/dependence and more major depressive episodes than Mexican Americans. Young non-Hispanic white women reported high rates of major depressive episodes and drug abuse/dependence. Alcohol abuse/dependence is highly prevalent among Mexican-American and non-Hispanic white men of any age. Mexican-American women infrequently abuse or become dependent on drugs or alcohol at any age. Dysthymia, panic disorder, and phobia are somewhat more prevalent among Mexican-American women over 40 years of age compared with both non-Hispanic white women over and Mexican-American women under 40 years of age. Antisocial personality is predominantly a disorder of young men of both ethnic groups.

BACKGROUND: Although relatively rare, cancer in teenagers and young adults (TYA) is the most common disease-related cause of death and makes a major contribution to years of life lost in this age group. There is a growing awareness of the distinctive needs of this age group and drive for greater understanding of how outcomes can be improved. We present here the latest TYA survival trends data for the United Kingdom (UK). METHODS: Using national cancer registry data, we calculated five-year relative survival for all 15-24 year olds diagnosed with cancer or a borderline/benign CNS tumour in the UK during the periods 1992-1996, 1997-2001 and 2002-2006. We analysed trends in survival for all cancers combined and for eighteen specified groups that together represent the majority of TYA cancers. We compared our data with published data for Europe, North America and Australia. RESULTS: Five-year survival for all cancers combined increased from 75.5% in 1992-1996 to 82.2% in 2002-2006 (P<0.001). Statistically significant improvements were seen for all disease groups except osteosarcoma, rhabdomyosarcoma, non-gonadal and ovarian germ cell tumours and ovarian and thyroid carcinomas. During the earliest time period, females had significantly better survival than males for five of the twelve non-gender-specific disease groups. By the latest period, only melanomas and non-rhabdomyosarcoma soft tissue sarcomas had differential survival by gender. Survival in the UK for the most recent period was generally similar to other comparable countries. CONCLUSION: Five-year survival has improved considerably in the UK for most cancer types. For some disease groups, there has been little progress, either because survival already approaches 100% (e.g. thyroid carcinomas) or, more worryingly for some cancers with poor outcomes, because they remain resistant to existing therapy (e.g. rhabdomyosarcoma). In addition, for a number of specific cancer types and for cancer as a whole males continue to have worse outcomes than females.
