Abstract
A relatively high proportion of people detained in forensic psychiatric hospitals have intellectual disabilities (up to 3000 people in the UK; Royal College of Psychiatrists, 2013), and people with intellectual disability are significantly over-represented among those psychiatric patients with long lengths of hospital stay (CQC, 2013; Vollm, 2015). People with mild to borderline intellectual disabilities are also prevalent in the UK prison system.Although the relationship between intelligence and offending is complex, lower intelligence is a known actuarial risk factor for offending behaviour. Studies, which have investigated the prediction of re-offending risk in populations with intellectual disability, have nevertheless found lower rates of recorded re-offending compared to those in mainstream forensic populations (e.g. Gray et al., 2010). The relatively high rate of ‘offending-like’ behaviour, which is not processed through the criminal justice system in people with intellectual disability makes risk prediction a more complex exercise with this group of people. It also makes outcomes measurement more difficult.This paper will give an overview of the current research evidence and clinical practice in the field of risk assessment, risk management and outcome measurement with offenders with intellectual disability. It will summarise the findings of a recent NIHR funded systematic review by the author, which pertains to this area, and will point to future developments in the field.Disclosure of interestThe author has not supplied his declaration of competing interest.

Abstract
Senescent cells play important roles in both physiological and pathological processes, including cancer and aging. In all cases, however, senescent cells comprise only a small fraction of tissues. Senescent phenotypes have been studied largely in relatively homogeneous populations of cultured cells. In vivo, senescent cells are generally identified by a small number of markers, but whether and how these markers vary among individual cells is unknown. We therefore utilized a combination of single‐cell isolation and a nanofluidic PCR platform to determine the contributions of individual cells to the overall gene expression profile of senescent human fibroblast populations. Individual senescent cells were surprisingly heterogeneous in their gene expression signatures. This cell‐to‐cell variability resulted in a loss of correlation among the expression of several senescence‐associated genes. Many genes encoding senescence‐associated secretory phenotype (SASP) factors, a major contributor to the effects of senescent cells in vivo, showed marked variability with a subset of highly induced genes accounting for the increases observed at the population level. Inflammatory genes in clustered genomic loci showed a greater correlation with senescence compared to nonclustered loci, suggesting that these genes are coregulated by genomic location. Together, these data offer new insights into how genes are regulated in senescent cells and suggest that single markers are inadequate to identify senescent cells in vivo.

Abstract
Background Docetaxel based therapy is one of the first line chemotherapeutic agents for the treatment of metastatic castrate-resistant prostate cancer. However, one of the major obstacles in the treatment of these patients is docetaxel-resistance. Defining the mechanisms of resistance so as to inform subsequent treatment options and combinations represents a challenge for clinicians and scientists. Previous work by our group has shown complex changes in pro and anti-apoptotic proteins in the development of resistance to docetaxel. Targeting these changes individually does not significantly impact on the resistant phenotype but understanding the central signalling pathways and transcription factors (TFs) which control these could represent a more appropriate therapeutic targeting approach. Methods Using a number of docetaxel-resistant sublines of PC-3 cells, we have undertaken a transcriptomic analysis by expression microarray using the Affymetrix Human Gene 1.0 ST Array and in conjunction with bioinformatic analyses undertook to predict dysregulated TFs in docetaxel resistant prostate cancer. The clinical significance of this prediction was ascertained by performing immunohistochemical (IHC) analysis of an identified TF (SRF) in the metastatic sites from men who died of advanced CRPC. Investigation of the functional role of SRF was examined by manipulating SRF using SiRNA in a docetaxel-resistant PC-3 cell line model. Results The transcription factors identified include serum response factor (SRF), nuclear factor kappa-B (NFκB), heat shock factor protein 1 (HSF1), testicular receptor 2 & 4 (TR2 &4), vitamin-D and retinoid x receptor (VDR-RXR) and oestrogen-receptor 1 (ESR1), which are predicted to be responsible for the differential gene expression observed in docetaxel-resistance. IHC analysis to quantify nuclear expression of the identified TF SRF correlates with both survival from date of bone metastasis (p = 0.003), survival from androgen independence (p = 0.00002), and overall survival from prostate cancer (p = 0.0044). Functional knockdown of SRF by siRNA demonstrated a reversal of apoptotic resistance to docetaxel treatment in the docetaxel-resistant PC-3 cell line model. Conclusions Our results suggest that SRF could aid in treatment stratification of prostate cancer, and may also represent a therapeutic target in the treatment of men afflicted with advanced prostate cancer.

Abstract
The non-canonical Wnt pathway, a regulator of cellular motility and morphology, is increasingly implicated in cancer metastasis. In a quantitative PCR array analysis of 84 Wnt pathway associated genes, both non-canonical and canonical pathways were activated in primary and metastatic tumors relative to normal prostate. Expression of the Wnt target gene PITX2 in a prostate cancer (PCa) bone metastasis was strikingly elevated over normal prostate (over 2,000-fold) and primary prostate cancer (over 200-fold). The elevation of PITX2 protein was also evident on tissue microarrays, with strong PITX2 immunostaining in PCa skeletal and, to a lesser degree, soft tissue metastases. PITX2 is associated with cell migration during normal tissue morphogenesis. In our studies, overexpression of individual PITX2A/B/C isoforms stimulated PC-3 PCa cell motility, with the PITX2A isoform imparting a specific motility advantage in the presence of non-canonical Wnt5a stimulation. Furthermore, PITX2 specific shRNA inhibited PC-3 cell migration toward bone cell derived chemoattractant. These experimental results support a pivotal role of PITX2A and non-canonical Wnt signaling in enhancement of PCa cell motility, suggest PITX2 involvement in homing of PCa to the skeleton, and are consistent with a role for PITX2 in PCa metastasis to soft and bone tissues. Our findings, which significantly expand previous evidence that PITX2 is associated with risk of PCa biochemical recurrence, indicate that variation in PITX2 expression accompanies and may promote prostate tumor progression and metastasis.

Abstract
Interplays among lineage-specific nuclear proteins, chromatin modifying enzymes, and the basal transcription machinery govern cellular differentiation, but their dynamics of action and coordination with transcriptional control are not fully understood. Alterations in chromatin structure appear to establish a permissive state for gene activation at some loci, but they play an integral role in activation at other loci. To determine the predominant roles of chromatin states and factor occupancy in directing gene regulation during differentiation, we mapped chromatin accessibility, histone modifications, and nuclear factor occupancy genome-wide during mouse erythroid differentiation dependent on the master regulatory transcription factor GATA1. Notably, despite extensive changes in gene expression, the chromatin state profiles (proportions of a gene in a chromatin state dominated by activating or repressive histone modifications) and accessibility remain largely unchanged during GATA1-induced erythroid differentiation. In contrast, gene induction and repression are strongly associated with changes in patterns of transcription factor occupancy. Our results indicate that during erythroid differentiation, the broad features of chromatin states are established at the stage of lineage commitment, largely independently of GATA1. These determine permissiveness for expression, with subsequent induction or repression mediated by distinctive combinations of transcription factors.

Abstract
Cardiac rehabilitation (CR) programs are recognized as integral part of the comprehensive care of patients with cardiovascular disease and are recommended as useful and effective (Class I) by the American Heart Association (AHA). In this study we used serial administration of the short form 36 (SF36) to evaluate patient's response to CR in terms of improvement in Health related Quality of Life. A total of 49 patients were included in the analysis. There was a significant improvement observed after CR in the Physical Capacity Score (42.3 vs 49.9 p = 0.0005). There was no significant improvement in the Mental Capacity Score (54.8 vs 54.9 p = 0.96). We conclude that Cardiac Rehabilitation Program causes a significant improvement in the health related quality of life of patients by improving their physical health and well being but does not improve the mental capacity which is already at a healthy level before CR.

Abstract
BACKGROUND Little research has been conducted investigating the way in which personality constructs relate to people with intellectual disabilities. The small amount of research that does exist suggests that underlying personality structure may be considerably different to that found in mainstream research. This hypothesis is, however, untested because so little work has been conducted with this population. METHOD Two circumplex models, the Interpersonal Adjective Scales and the CIRCLE, were employed to explore the factor structure, coherence and fit of these models with this population. One hundred and twenty-three participants from forensic intellectual disability services were rated by staff on the assessments, although not all assessments were completed for all participants. RESULTS The factor structures for both assessments conform broadly with a theoretical structure. Hypotheses concerning the magnitude and direction of Spearman's correlations both within and between assessments were generally confirmed. CONCLUSION While results would support the applicability of mainstream personality assessments to this client group, cautions were expressed in relation to the source of the sample and to the method of data collection.

Abstract
Transmembrane serine protease 2 (TMPRSS2) is an androgen-regulated member of the type two transmembrane protease (TTSP) family. Two other members of the TTSP family, matriptase and hepsin, are over-expressed in prostate adenocarcinoma and mechanistically influence cancer cell invasion and metastasis. This study was performed to determine TMPRSS2 protein expression in primary and metastatic prostate cancers. We developed a monoclonal antibody capable of the sensitive and specific detection of TMPRSS2 protein. TMPRSS2 regulation by androgen and presence in seminal fluid was measured. TMPRSS2 localization and expression was evaluated in 415 cases of primary prostate cancer and 144 prostate cancer metastases by immunohistochemistry. We determined that TMPRSS2 protein expression is regulated by androgens and that TMPRSS2 is a component of the normal seminal fluid proteome. TMPRSS2 protein is abundantly expressed in the prostate, with low levels in the epithelia of the colon, stomach, epididymis and breast. Pancreatic acini, hepatic bile ducts, testicular Leydig cells and the kidney also express TMPRSS2. In the prostate, TMPRSS2 protein is specifically localized to the secretory epithelium, with enhanced expression in the plasma membrane orientated towards the ductal lumen. TMPRSS2 expression was significantly higher in both neoplastic prostate and in the epithelium of prostatic hyperplasia compared to normal epithelium (p < 0.01). TMPRSS2 expression was further elevated in higher Gleason grade cancers (patterns 4 and 5) compared to pattern 3 (p = 0.04). Furthermore, in most high-grade cancers, TMPRSS2 was mislocalized, being expressed in the cytoplasm as well as in the cell membrane. Prostate cancer metastases also generally expressed high levels of TMPRSS2. In summary, the TMPRSS2 protease is expressed highly in primary and metastatic prostate cancers and is associated with tumour cell differentiation. Based on studies with the related proteins matriptase and hepsin, TMPRSS2 should be investigated for causal roles in prostate carcinogenesis.

Abstract
BACKGROUND Despite an increasing knowledge base concerning the assessment of emotional and behavioural problems in people with intellectual disabilities (ID), relatively little research has examined such problems in offenders with ID. METHODS The study assessed 172 male offenders with ID in three service settings (high, medium-low security and community) using the Behaviour Rating Scale of the Emotional Problem Scales (EPS), with the aim of assessing differences in Externalizing and Internalizing Behaviour Problems. RESULTS Normative information is presented on the Behaviour Rating Scale of the EPS across three levels of forensic ID care. It was found that offenders in higher secure care scored higher on sub-scales reflecting physical aggression than those in lower secure care. However, there was no difference in terms of other Externalizing Behaviour Problems, such as verbal aggression, non-compliance or hyperactivity. In addition, those offenders in higher secure care scored significantly higher on all Internalizing Behaviour Problems sub-scales, including anxiety, depression and low self-esteem. CONCLUSIONS Implications for research and clinical practice are discussed, including the utility of the EPS as a measure of clinical need and treatment outcome.

Abstract
The VHL gatekeeper tumour suppressor gene is inactivated in the familial cancer syndrome von Hippel-Lindau disease and in most sporadic clear cell renal cell carcinomas. Recently the VHL gene product has been identified as a specific component of a SCF-like complex, which regulates proteolytic degradation of the hypoxia inducible transcription factors HIF-1 and HIF-2. pVHL is critical for normal development and mRNA expression studies suggest a role in nephrogenesis. Despite the importance of VHL in oncogenesis and development, little is known about the regulation of VHL expression. To investigate VHL promoter activity, we performed comparative sequence analysis of human, primate, and rodent 5' VHL sequences. We then proceeded to deletion analysis of regions showing significant evolutionary conservation between human and rat promoter sequences, and defined two positive and one negative regulatory regions. Analysis of specific putative transcription factor binding sites identified a functional Sp1 site, which was shown to be a regulatory element. Overlapping Sp1/AP2 sites were also identified and candidate E2F1 binding sites evaluated. Three binding sites for as yet unidentified transcription factors were mapped also. These investigations provide a basis for elucidating the regulation of VHL expression in development, the molecular pathology of epigenetic silencing of VHL in tumourigenesis, and suggest a possible link between Sp1, VHL, and nephrogenesis.

Abstract
The genetic events involved in the aetiology of non-clear-cell renal cell carcinoma (RCC) and a proportion of clear cell RCC remain to be defined. Germline mutations of the TSC1 and TSC2 genes cause tuberous sclerosis (TSC), a multi-system hamartoma syndrome that is also associated with RCC. We assessed 17 sporadic clear cell RCCs with a previously identified VHL mutation, 15 clear-cell RCCs without an identified VHL mutation and 15 non-clear-cell RCCs for loss of heterozygosity (LOH) at chromosomes 9q34 and 16p13.3, the chromosomal locations of TSC1 and TSC2. LOH was detected in 4/9, 1/11 and 3/13 cases informative at both loci. SSCP analysis of the whole coding region of the retained allele did not reveal any cases with a detectable intragenic second somatic mutation. Furthermore, RT-PCR analysis of TSC1 and TSC2 on total RNA from 8 clear-cell RCC cell lines confirmed expression of both TSC genes. These data indicate that biallelic inactivation of TSC1 or TSC2 is not frequent in sporadic RCC and suggests that the molecular mechanisms of renal carcinogenesis in TSC are likely to be distinct.

Abstract
Renal cell carcinoma (RCC), the most common adult kidney neoplasm, is histopathologically heterogeneous, with most sporadic RCCs ( approximately 80%) classified as clear cell (CC) tumors. Chromosome 3p allele loss is the most frequent genetic alteration in RCC but is associated specifically with sporadic and hereditary forms of clear cell RCC (CC-RCC) and is not a feature of non-CC-RCC, such as papillary (chromophilic) RCC. The VHL tumor suppressor gene (TSG) maps to chromosome 3p25, and somatic inactivation of the VHL gene occurs in up to 70% of CC-RCC tumors and cell lines. However, VHL inactivation is not sufficient for CC-RCC tumorigenesis, and inactivation of 3p12-p21 TSG(s) appears to be necessary in CC-RCC irrespective of VHL gene inactivation status. Recently, we demonstrated that the candidate 3p21 TSG, RASSF1A, is hypermethylated in most small cell lung cancers. We have now investigated the role of RASSF1A inactivation in primary RCC tumors. RASSF1A promoter methylation was detected in 23% (32 of 138) of primary CC-RCC tumors. In CC-RCC cell lines, RASSF1A methylation was associated with silencing of RASSF1A expression and restoration of expression after treatment with 5'-azacytidine. The frequency of RASSF1A methylation was similar in CC-RCC with and without VHL gene inactivation (24% versus 21%), and there was no association between epigenetic silencing of the RASSF1A and VHL TSGs, because 0 of 6 tumors with VHL hypermethylation had RASSF1A methylation, and VHL was not methylated in 26 CC-RCCs with RASSF1A methylation. Although 3p allele loss has been reported rarely in papillary RCC, we identified RASSF1A methylation in 44% (12 of 27) of papillary RCCs analyzed. Thus: (a) inactivation of RASSF1A is a frequent event in both CC-RCC and papillary RCC tumors; (b) there is no relationship between epigenetic silencing of RASSF1A and VHL inactivation status in CC-RCC. Fifty-four CC-RCCs analyzed for RASSF1A methylation were informative for 3p21 allele loss, and 20% (7 of 35) with 3p21 allele loss demonstrated RASSF1A methylation. All informative CC-RCCs with 3p21 allele loss and no RASSF1A methylation also demonstrated allele losses at other regions of 3p so that tumorigenesis in these cases may result from: (a) haploinsufficiency of RASSF1A; (b) inactivation of other 3p21 TSGs; or (c) inactivation of 3p TSGs from outside of 3p21. RASSF1A is the first TSG to be inactivated frequently in both papillary and CC-RCCs. The finding of frequent epigenetic inactivation of RASSF1A in papillary RCCs despite previous studies reporting infrequent 3p21 allele loss in this tumor type illustrates how the systematic identification of all major human cancer genes will require detailed analysis of the cancer genome and epigenome.

Abstract
We have developed and validated a robust antigen capture assay for the measurement of serum clusterin. Increased clusterin expression, and alterations in serum clusterin levels have been associated with a number of disease states. In particular, clusterin has been shown to be associated with tissue regression and apoptosis in the rat ventral prostate in response to androgen ablation or administration of anti-androgens. The object of this study was to determine if changes in human serum clusterin can be used as a diagnostic or prognostic marker to monitor the response to hormonal therapy in patients with prostate cancer, and to determine if clusterin concentrations increase with the progression towards androgen independence. The antigen capture assay was used for an extensive analysis of human serum clusterin concentration in fasting males, and to determine if there is any relationship between clusterin and age or cholesterol levels. The average clusterin level in serum is 101+/-42 microg/ml (n=96). There is no correlation to age or serum cholesterol levels. Analysis of serum clusterin levels in patients with newly diagnosed prostate cancer (n=5), hormone responsive tumors (n=5), and hormone refractory disease (n=5), demonstrates that no significant changes in serum clusterin levels accompany the progression of prostatic disease, or response to hormone therapy.

Abstract
OBJECTIVE To describe a new syndrome characterised by embryonic mortalities, stillbirths, mummified foetuses and congenital malformations in a herd of intensively farmed pigs. DESIGN Field observations, laboratory investigations and examination of breeding records. PROCEDURE Pathology examinations were performed on mummified and congenitally deformed piglets during an outbreak of reproductive disease at a 2600 sow intensive piggery in New South Wales from April to October 1997. Reproductive performance was monitored during the outbreak and breeding records were examined retrospectively. Serum and tissue samples from pigs were tested for evidence of infection with known porcine pathogens and for a new virus, Menangle virus, isolated from stillborn piglets with deformities from the affected piggery in August 1997. RESULTS Reproductive disease occurred sequentially in all four breeding units at the affected piggery over a period of 21 weeks. The farrowing percentages in each unit decreased from 80 to 82% before the outbreak to 63 to 78% during the outbreak and the number of live piglets per litter declined from a mean of 9.6 to 9.8 before the outbreak to 7.2 to 8.9 during the outbreak. The proportion of affected litters (litters with less than six liveborn piglets) was highest (64%) in the sixth week of the outbreak. Mummified foetuses, stillborn piglets with arthrogryposis, craniofacial deformities and degeneration of the brain and spinal cord, were observed along with occasional abortions. Sera from sows that produced affected litters contained neutralising antibodies against Menangle virus and there was evidence that this virus had been introduced to the piggery in February 1997. CONCLUSIONS Reproductive disease in pigs due to Menangle virus was characterised by stillbirths, mummification, embryonic death and infertility, along with abortions, skeletal deformities and degeneration of the brain and spinal cord in affected foetuses and stillborn piglets.

Abstract
After hormonal ablation, 90% of the secretory epithelial cells of the prostate undergo apoptosis, and the remaining cells are reorganized as the tissue is remodeled. Using differential display RT-PCR of total RNA extracted from the rat ventral prostate before and 4 days after castration, we have cloned and sequenced a number of complementary DNAs whose cognate messenger RNAs (mRNAs) may be either up- or down-regulated during prostatic regression. One sequence of particular interest, 25.2, is up-regulated after castration and is homologous to p190, a protein associated with cytoskeletal reorganization. RT-PCR has confirmed that the steady state level of p190A mRNA is increased in the rat ventral prostate after castration, and Western blot analysis indicates that the protein levels for p190A also increase. The steady state level of p190B mRNA, the second isoform of p190, does not appear to change significantly after hormone ablation. Immunohistochemical analysis demonstrates that p190A is up-regulated primarily in the columnar epithelial cells that actively undergo cell death after hormone ablation. As Rho-GAP signaling had been shown to be influenced by p190 levels, leading to the disassembly of focal adhesion contacts and the loss of cytoskeletal architecture, we also measured the changes in Rho-GAP during prostate regression. Rho-GAP levels do not change significantly, suggesting that changes in stoichiometry of the interaction between p190A and Rho-GAP may be a prerequisite for the initiation of cytoplasmic condensation. These intracellular events coupled with the proteolytic degradation of the extracellular matrix appear to be integral to the apoptotic process in glandular epithelia.

Abstract
Clusterin was first characterized as an apoptosis-associated transcript after it was identified as testosterone-repressed prostate message (TRPM-2) that is expressed in the epithelial cells of the regressing rat ventral prostate. Increases in clusterin mRNA and protein have been consistently detected in apoptotic cell death paradigms, establishing clusterin gene expression as a prominent marker of apoptotic cell loss. However, enhanced protein expression has also been reported in surviving cells. This ambiguity makes it difficult to define the contribution of clusterin to apoptosis. To address this problem, a panel of polyclonal and monoclonal antibodies were raised against the clusterin alpha-chain, beta-chain, and mixed alpha/beta epitopes. These antibodies detect changes in the biogenesis of clusterin during apoptosis by Western analysis and immunohistochemistry. A 42-kDa glyco/isoform of clusterin appears to be up-regulated in dying epithelial cells. This glyco/isoform is apparently generated as a result of apoptosis-induced stimulation of a normal but under-utilized, synthetic pathway. These data demonstrate that clusterin synthesized by apoptotic cells can be immunologically distinguished from clusterin synthesized by surviving cells in damaged tissue.

Abstract
This paper describes a small-scale survey undertaken with 300 nurses, midwives and health visitors on post-registration courses and registered for the ENB Higher Award. The aim was threefold: first to examine reasons for electing to use particular libraries; second, the relationship between workplace, home, teaching site and choice of library services; and third, the use of library enquiry services. There was a 56% response rate to the postal questionnaire and results indicated that the key factor in selecting a library was availability of resources rather than convenience to home or workplace. The third largest group of respondents worked in community organizations with little or no on-site access to resources and were dependent on access to other libraries. Most who used the library for literature searching needed to seek help in spite of preliminary user education sessions. Similar levels of assistance were needed to locate journals and use the computerized book catalogue. The paper recommends explicit information on strategic entry points, necessity of a broad central collection, integration of information retrieval into post-registration courses, use of self-study packs, better trust/university liaison and recognition of the need for resource transfer from teaching to learning.
