Abstract
PURPOSE The incidence of psychotic disorders varies according to the geographical area, and it has been investigated whether neighbourhood level factors may be associated with this variation. The aim of this systematic review is to collate and appraise the literature on the association between social deprivation and the incidence or risk for psychotic disorders. METHOD A systematic review was conducted, and studies were included if they were in English, provided a measure of social deprivation for more than one geographically defined area and examined either the correlation, rate ratio or risk of psychotic disorder. A defined search strategy was undertaken with Medline, CINAHL Plus and PsychInfo databases. RESULTS A total of 409 studies were identified in the search, of which 28 fulfilled the inclusion criteria. Of these, four examined the association between social deprivation at the time of birth, three examined the putative prodrome of psychosis or those at ultra-high risk (UHR) for psychosis, and 23 examined the time at presentation with a first episode of psychosis (FEP) (one study examined two time points and one study included both UHR and FEP). Three of the studies that examined the level of social deprivation at birth found an association with a higher risk for psychotic disorders and increased social deprivation. Seventeen of the 23 studies found that there was a higher risk or rate of psychotic disorders in more deprived neighbourhoods at the time of presentation; however, adjusting for individual factors tended to weaken this association. Limited research has been conducted in the putative prodromal stage and has resulted in conflicting findings. CONCLUSIONS Research conducted to date has not definitively identified whether the association is a result of social causation or social drift; however, the findings do have significant implications for service provision, such as the location and access of services.

Abstract
Language disturbance has a central role in the presentation of psychotic disorders however its relationship with functioning requires further clarification, particularly in first episode psychosis (FEP). Both language disturbance and functioning can be evaluated with clinician-rated and performance-based measures. We aimed to investigate the concurrent association between clinician-rated and performance-based measures of language disturbance and functioning in FEP. We assessed 108 individuals presenting to an Early Intervention in Psychosis Service in Ireland. Formal thought disorder (FTD) dimensions and bizarre idiosyncratic thinking (BIT) were rated with structured assessment tools. Functioning was evaluated with a performance-based instrument, a clinician-rated measure and indicators of real-world functioning. The disorganisation dimension of FTD was significantly associated with clinician-rated measures of occupational and social functioning (Beta=-0.19, P<0.05 and Beta=-0.31, P<0.01, respectively). BIT was significantly associated with the performance-based measure of functioning (Beta=-0.22, P<0.05). Language disturbance was of less value in predicting real-world measures of functioning. Clinician-rated and performance-based assessments of language disturbance are complementary and each has differential associations with functioning. Communication disorders should be considered as a potential target for intervention in FEP, although further evaluation of the longitudinal relationship between language disturbance and functioning should be undertaken.

Abstract
OBJECTIVE The aim of the present study was to assess the effects of pomegranate juice on the level of oxidative stress in the blood of endurance-based athletes. Pomegranate juice is rich in polyphenols, conferring it a higher antioxidant capacity than other beverages with polyphenolic antioxidants. METHODS A randomized double-blind, multicenter trial was performed in athletes from three different sport clubs located in southeastern of Spain. Plasma oxidative stress markers (protein carbonyls and malondialdehyde [MDA]) as well as C-reactive protein and sE-selectin were measured. Thirty-one athletes participated in the study. Participants were divided into three groups. The first group was supplemented with 200 mL/d pomegranate juice (PJ; n = 10) over a 21-d period, the second with 200 mL/d pomegranate juice diluted 1:1 with water (PJD; n = 11), and a control group that did not consume pomegranate juice (C; n = 10). Nine athletes were excluded due to protocol violations (n = 4 in the PJ group and n = 5 in the PJD group) because they did not observe the 24 h of rest before the last blood test. RESULTS The control group increased levels of carbonyls (+0.7 ± 0.3 nmols/mg protein) and MDA (+3.2 ± 1.0 nmols/g protein), whereas the PJ and PJD groups maintained or decreased their levels, respectively. On the other hand, lactate levels increased in the PJ group (from 10.3 at day 0 to 21.2 mg/dL at day 22). A nonsignificant decrease was detected in sE-selectin and C-reactive protein in the groups consuming pomegranate juice. CONCLUSION Consumption of pomegranate juice over a 21-d period improved MDA levels and carbonyls, and thus decreased the oxidative damage caused by exercise.

Abstract
Diabetes is currently the world's fastest growing chronic disease and it is caused by deficient production of insulin by the endocrine pancreas or by abnormal insulin action in peripheral tissues. This results in persistent hyperglycaemia that over time may produce chronic diabetic complications. Determination of glycated haemoglobin level is currently the gold standard method to evaluate and control sustained hyperglycaemia in diabetic people. This measurement is currently made by high-performance liquid chromatography, which is a complex chemical process that requires the extraction of blood from the antecubital vein. To reduce the complexity of that measurement, we propose a fully-optical technique that is based in the fact that there are changes in the optical properties of erythrocytes due to the presence of glucose-derived adducts in the haemoglobin molecule. To evaluate these changes, we propose to perform quantitative phase maps of erythrocytes by using telecentric digital holographic microscopy. Our experiments show that telecentric digital holographic microscopy allows detecting, almost in real time and from a single drop of blood, significant differences between erythrocytes of diabetic patients and healthy patients. Besides, our phase measurements are well correlated with the values of glycated haemoglobin and the blood glucose values.

Abstract
BACKGROUND Sickness certification poses significant challenges to most general practitioners (GPs). As an alternative form of certification, in 2010, the UK implemented the 'fit note', which focuses on returning to work after illness. It has been well received in the UK but little is known of non-UK GP attitudes towards the fit note. AIMS To evaluate the challenges Irish GPs experience with the current sickness certification system and their attitudes towards the fit note. METHODS A questionnaire assessing attitudes, practices and preferences regarding the fit note was developed, piloted and posted to a representative sample of Irish GPs selected by systematic sampling. Descriptive statistics, chi-square tests and binary logistic regression were used to analyse the results. RESULTS Of 305 GPs surveyed, 64% (196) completed the survey. Ninety per cent (177) of responders reported a lack of available rehabilitation services for patients on sick leave and 66% (124) reported adverse effects of sickness certification on therapeutic relationships with patients. Those who indicated a preference for introducing the fit note (53%; 104) were significantly more likely to endorse both an excessive focus on disability [odds ratio (OR) = 3.16] and lack of GP training (OR = 2.04) in the sickness certification process. CONCLUSIONS Difficulties associated with sickness certification are apparent at GP-patient, GP-employer and GP-health service levels. Addressing these will require intervention at each of these levels and may be facilitated by challenging the assumption that illness equates to disability.

Abstract
BACKGROUND Formal thought disorder (FTD) is a core feature of psychosis, however there are gaps in our knowledge about its prevalence and factor structure. We had two aims: first, to establish the factor structure of FTD; second, to explore the clinical utility of dimensions of FTD in order to further the understanding of its nosology. METHODS A cross-validation study was undertaken to establish the factor structure of FTD in first episode psychosis (FEP). The relative utility of FTD categories vs. dimensions across diagnostic categories was investigated. RESULTS The prevalence of clinically significant FTD in this FEP sample was 21%, although 41% showed evidence of disorganised speech, 20% displayed verbosity and 24% displayed impoverished speech. A 3-factor model was identified as the best fit for FTD, with disorganisation, poverty and verbosity dimensions (GFI=0.99, RMR=0.07). These dimensions of FTD accurately distinguished affective from non-affective diagnostic categories. A categorical approach to FTD assessment was useful in identifying markers of clinical acuteness, as identified by short duration of untreated psychosis (OR=2.94, P<0.01) and inpatient treatment status (OR=3.98, P<0.01). CONCLUSION FTD is moderately prevalent and multi-dimensional in FEP. Employing both a dimensional and categorical assessment of FTD gives valuable clinical information, however there may be a need to revise our conceptualisation of the nosology of FTD. The prognostic value of FTD, as well as its neural basis, requires elucidation.

Abstract
Voluntarily admitted service users can report levels of perceived coercion comparable to those admitted involuntarily, yet little is known of this groups longer term outcome. The 'coerced voluntary' had a score of 4 or above on the MacArthur perceived coercion scale and one year after discharge, they had a better therapeutic relationship compared to involuntarily admitted service users. There was no difference between the coerced voluntary, uncoerced voluntary and involuntary groups in engagement, satisfaction and functioning.

Abstract
While knowledge on service users' perspective on their admissions to psychiatric wards has improved substantially in the last decade, there is a paucity of knowledge of the perspectives of caregivers. This study aimed to determine caregiver's perception of the levels of perceived coercion, perceived pressures and procedural justice experienced by service users during their admission to acute psychiatric in-patient units. The perspective of caregivers were then compared to the perspectives of their related service users, who had been admitted to five psychiatric units in Ireland. Caregivers were interviewed using an adapted version of the MacArthur admission experience interview. Sixty-six caregivers participated in this study and the majority were parents. Seventy one percent of service users were admitted involuntarily and nearly half had a diagnosis of schizophrenia or schizoaffective disorder. Caregivers of involuntarily admitted individuals perceived the service users' admission as less coercive than reported by the service users. Caregivers also perceived a higher level of procedural justice in comparison to the level reported by service users. Reducing the disparity of perceptions between caregivers and service users could result in caregivers having a greater understanding of the admission process and why some service users may be reluctant to be admitted.

Abstract
OBJECTIVES The study aimed to determine the number of accumulated coercive events experienced by patients during inpatient admission, the patients' functioning and quality of life (QOL) one year after discharge, and associations between these variables and patient characteristics and between follow-up outcomes and number of accumulated coercive events. METHODS A prospective cohort study was undertaken at three community services and an independent hospital in Ireland (N=162). Accumulated coercive events scores were based on patients' legal status, perceived coercion, and exposure to physical restraint, seclusion, or forced medication. RESULTS Most (68%) experienced at least one coercive event. Lower functioning predicted more coercive events. At follow-up, the mean subjective QOL score was 63% of the highest possible score, objective QOL improved for 15% of participants, and functioning improved for 70%. Accumulated coercive events did not predict these outcomes. CONCLUSIONS Coercive events during psychiatric admission appeared unrelated to functioning and QOL at follow-up.

Abstract
BACKGROUND Authors of the Diagnostic and Statistical Manual, Fifth Edition (DSM-V) have recommended to "integrate dimensions into clinical practice." The epidemiology and associated phenomenology of formal thought disorder (FTD) have been described but not reviewed. We aimed to carry out a systematic review of FTD to this end. METHODS A systematic review of FTD literature, from 1978 to 2013, using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. RESULTS A total of 881 abstracts were reviewed and 120 articles met inclusion criteria; articles describing FTD factor structure (n = 15), prevalence and longitudinal course (n = 41), role in diagnosis (n = 22), associated clinical variables (n = 56), and influence on outcome (n = 35) were included. Prevalence estimates for FTD in psychosis range from 5% to 91%. Dividing FTD into domains, by factor analysis, can accurately identify 91% of psychotic diagnoses. FTD is associated with increased clinical severity. Poorer outcomes are predicted by negative thought disorder, more so than the typical construct of "disorganized speech." CONCLUSION FTD is a common symptom of psychosis and may be considered a marker of illness severity. Detailed dimensional assessment of FTD can clarify diagnosis and may help predict prognosis.

Abstract
The quality of general practitioner (GP) ophthalmology referrals to emergency departments has been reported to be sub-optimal. It is possible that a lack of adequate formal training in ophthalmology for GPs contributes to this situation. Data in this study was obtained from a postal survey of GPs to ascertain their knowledge of, and confidence with, clinical ophthalmology skills as well as their training in this speciality. Undergraduate ophthalmology training was rated as inadequate by 35/50 (70%) respondents. 28 (56%) respondents reported to be confident with their clinical ophthalmology skills. 19 (38%) GPs reported to have good knowledge of ophthalmology, and this was strongly associated with a positive appraisal of their undergraduate ophthalmology training (92%, P < 0.01), having experience working in an ophthalmology department (80%, p = 0.14) and having received GP training abroad (52%, p = 0.16). Regarding ophthalmology equipment, 47 (94%) GPs reported to have an ophthalmoscope but only 33 (66%) were confident with its use and just 20 (40%) could confidently distinguish an abnormal optic disc. Lack of knowledge of ophthalmology may have a significant impact on patient care and could be addressed by including clinical skills training in GP specialist training or continuing professional development schemes.

Abstract
Human adipose mesenchymal stem cells are a heterogeneous population, where cell cultures derived from single-cell-expanded clones present varying degrees of differential plasticity. This work focuses on the immunomodulatory/anti-inflammatory properties of these cells. To this end, five single-cell clones were isolated (generally called 1.X and 3.X) from two volunteers. Regarding the expression level of the lineage-characteristic surface antigens, clones 1·10 and 1·22 expressed the lowest amounts, while clones 3·10 and 3·5 expressed more CD105 than the rest and clone 1·7 expressed higher amounts of CD73 and CD44. Regarding cytokine secretion, all clones were capable of spontaneously releasing high levels of interleukin (IL)-6 and low to moderate levels of IL-8. These differences can be explained in part by the distinct methylation profile exhibited by the clones. Furthermore, and after lipopolysaccharide stimulation, clone 3.X produced the highest amounts of proinflammatory cytokines such as IL-1β, while clones 1·10 and 1·22 highly expressed IL-4 and IL-5. In co-culture experiments, clones 1.X are, together, more potent inhibitors than clones 3.X for proliferation of total, CD3(+) T, CD4(+) T and CD8(+) T lymphocytes and natural killer (NK) cells. The results of this work indicate that the adipose stem cell population is heterogeneous in cytokine production profile, and that isolation, characterization and selection of the appropriate cell clone is a more exact method for the possible treatment of different patients or pathologies.

Abstract
The legal status of service users admitted to psychiatric wards is not synonymous with the level of coercion that they can perceive during the admission. This study aimed to identify and describe the proportion of individuals who were admitted voluntarily but experienced levels of perceived coercion comparable to those admitted involuntarily. Individuals admitted voluntarily and involuntarily to three psychiatric hospitals were interviewed using the MacArthur Admission Experience Interview and the Structured Clinical Interview for DSM-IV diagnoses. One hundered sixty-one individuals were interviewed and 22% of the voluntarily admitted service users had levels of perceived coercion similar to that of the majority of involuntarily admitted service users. Voluntarily admitted service users who experienced high levels of perceived coercion were more likely to have more severe psychotic symptoms, have experienced more negative pressures and less procedural justices on admission. Individuals brought to hospital under mental health legislation but who subsequently agreed to be admitted voluntarily and those treated on a secure ward also reported higher levels of perceived coercion. It needs to be ensured that if any service user, whether voluntary or involuntary, experiences treatment pressures or coercion that there is sufficient oversight of the practice, to ensure that individual's rights are respected.

Abstract
In most clinical trials, human mesenchymal stem cells (hMSCs) are expanded in vitro before implantation. The genetic stability of human stem cells is critical for their clinical use. However, the relationship between stem-cell expansion and genetic stability is poorly understood. Here, we demonstrate that within the normal expansion period, hMSC cultures show a high percentage of aneuploid cells that progressively increases until senescence. Despite this accumulation, we show that in a heterogeneous culture the senescence-prone hMSC subpopulation has a lower proliferation potential and a higher incidence of aneuploidy than the non-senescent subpopulation. We further show that senescence is linked to a novel transcriptional signature that includes a set of genes implicated in ploidy control. Overexpression of the telomerase catalytic subunit (human telomerase reverse transcriptase, hTERT) inhibited senescence, markedly reducing the levels of aneuploidy and preventing the dysregulation of ploidy-controlling genes. hMSC-replicative senescence was accompanied by an increase in oxygen consumption rate (OCR) and oxidative stress, but in long-term cultures that overexpress hTERT, these parameters were maintained at basal levels, comparable to unmodified hMSCs at initial passages. We therefore propose that hTERT contributes to genetic stability through its classical telomere maintenance function and also by reducing the levels of oxidative stress, possibly, by controlling mitochondrial physiology. Finally, we propose that aneuploidy is a relevant factor in the induction of senescence and should be assessed in hMSCs before their clinical use.

Abstract
OBJECTIVE Service users may express positive, ambivalent, or negative views of their hospital admission. The objective of this study was to determine whether the background of the interviewer-service user-researcher or clinician-influences the information elicited. The primary outcome was the level of perceived coercion on admission, and secondary outcomes were perceived pressures on admission, procedural justice, perceived necessity for admission, satisfaction with services, and willingness to consent to participate in the study. METHODS Participants voluntarily and involuntarily admitted to three hospitals in Ireland were randomly allocated to be interviewed at hospital discharge by either a service user-researcher or a clinician. Interviewers used the MacArthur Admission Experience Survey and the Client Satisfaction Questionnaire. RESULTS A total of 161 participants were interviewed. No differences by interviewer status or by admission status (involuntary or voluntary) were found in levels of perceived coercion, perceived pressures, procedural justice, perceived necessity, or satisfaction with services. Service users were more likely to decline to participate if their consent was sought by a service user-researcher (24% versus 8%, p=.003). CONCLUSIONS Most interviewees gave positive accounts of their admission regardless of interviewer status. The findings indicate that clinicians and researchers can be more confident that service users' positive accounts of admissions are not attributable to a response bias. Researchers can also feel more confident in directly comparing the results of studies undertaken by clinicians and by service user-researchers.

Abstract
OBJECTIVES The Mental Health Act 2001 (MHA 2001) was implemented in November 2006. Since that time, there has been considerable research into its impact, including the impact on service provision, use of coercive practices and the perceptions by key stakeholders. Our objective is to present a summary of research into the MHA 2001 since its implementation in the Irish state in the context of international standards and practice. METHODS We reviewed the literature presented on Medline and Google Scholar, directly assessed relevant journals and sought abstract information from the College of Psychiatry of Ireland. RESULTS There has been a small decrease in the rate of involuntary admission since implementation but there has been no change in the representativeness of diagnoses of individuals admitted involuntarily. Mental Health Tribunals were held for 57% of those admitted involuntarily and 46% of service users found that the Mental Health Tribunal made the involuntary admission easier to accept. One year after discharge, 60% of service users reflected that their involuntary admission had been necessary. Professional groups have expressed concerns regarding workload, training time for junior doctors and paperwork. CONCLUSIONS The MHA 2001 has brought the practice of involuntary admission further into line with international standards. However, five years after the implementation of the Act international guidelines and practice have highlighted areas in need of further reform, including capacity legislation and consideration of advance directives and community treatment orders. Further research is also lacking on caregivers' or family members' perceptions of the MHA 2001.

Abstract
OBJECTIVES To investigate the effectiveness of bipolar radiofrequency-induced thermal therapy (RFITT) in a multicentre non-randomized study. METHODS Some 672 incompetent saphenous veins (85% great saphenous varicose vein, 15% short saphenous vein) in 462 patients (56.5% CEAP [clinical, aetiological, anatomical and pathological elements] class 3 or worse) were treated in eight European centres. Patients were assessed between 180 and 360 days postoperatively. Occlusion rates were determined by duplex ultrasound and compared with the power used for treatment, pull back rate and experience of the operating surgeon. RESULTS Complete occlusion rates of 98.4% were achieved when treatments were performed by an experienced operator (more than 20 cases), when the maximum power setting on the RFITT generator was between 18 and 20 W and the applicator was withdrawn at a rate slower than 1.5 second/cm CONCLUSIONS RFITT is efficacious, well tolerated by patients and has a low incidence of procedure-related post-operative complications.
