Mind your head: a student guide to mental health (2010)

This booklet is full of practical tips and information on managing stress and achieving and maintaining positive mental health and emotional wellbeing. It also contains a comprehensive list of helpful local organisations and websites. The booklet targets first year students at university and further and higher education colleges as the transition from school to further education can be a very stressful time.

Copeptin, a stable peptide derived from the vasopressin precursor, correlates with the individual stress level.

BACKGROUND: During stress, vasopressin is a potent synergistic factor of CRH as a hypothalamic stimulator of the HPA axis. The measurements of CRH and vasopressin levels are cumbersome because of their instability and short half-life. Copeptin is a more stable peptide stoichiometrically released from the same precursor molecule. The aim of our study was to compare copeptin and cortisol levels in different stress situations. METHODS: Three groups of patients with increasing stress levels were investigated: a) healthy controls without apparent stress (n=20), b) hospitalized medical patients with moderate stress (n=25) and c) surgical patients 30 minutes after extubation, with maximal stress (n=29). In all patients we assessed cortisol and copeptin levels. Copeptin levels were measured with a new sandwich immunoassay. RESULTS: Cortisol levels in controls were (median, IQ range, 486 [397-588] nmol/L), not significantly different as compared to medical patients (438 [371-612] nmol/L, p=0.69). Cortisol levels in surgical patients after extubation were higher (744 [645-1062] nmol/L p<0.01 vs controls and medical patients). Copeptin levels in controls were 4.3 [3.2-5.5] pmol/L, which was lower as compared to medical patients (17.5 [6.4-24.1], p<0.001) and surgical patients after extubation (67.5 [37.8-110.0] pmol/L, p<0.001). The correlation between copeptin levels and cortisol was r=0.46, p<0.001. CONCLUSION: Copeptin is a novel marker of the individual stress level. It more subtly mirrors moderate stress as compared to cortisol values.

Neurological conditions: involvement to improve service delivery

A major, ongoing Public Health Agency led consultation exercise has identified 12 recommendations to improve the lives of the 48,000 people, and their carers, who experience neurological conditions across Northern Ireland. These recommendations will form the basis of an action plan to improve service delivery and support for those experiencing a range of conditions, such as epilepsy, Huntington's Disease, Parkinson's Disease, progressive supranuclear palsy (PSP) and multiple sclerosis (MS).The recommendations cover four areas:accurate information and diagnosis;control and choice, particularly self-management and person-centred services;day-to-day living and independence, including finance, employment, social life and ability to get out and about;emotional and psychological impact on individuals and families, eg the support available to deal with stress, fear, frustration, isolation, loss and vulnerability associated with living with a neurological condition.The report was launched at a regional workshop, held in Cookstown (today) and co-ordinated through the Neurological Conditions Network, which was established to develop this work.Speaking before the workshop, Health Minister Edwin Poots said: "Neurological conditions give rise to complex needs, which require support from a wide range of professionals. They also change lives, both for those directly affected and for their families and carers, and it is so important not to lose sight of this if we are to successfully address the challenges in tackling neurological conditions."Last week, I visited the home of Beth McCune, who suffers from motor neurone disease. I was invited to see for myself the daily challenges faced by Beth and her husband and carer, Arthur, and to hear of their experiences. While I was struck by their courage and patience, this visit underlined again for me the severe life-changing impact of the disease."At present, there are some 48,000 people in Northern Ireland living with neurological conditions. It was in recognition of the needs of men and women like Beth that my department requested the establishment of the Neurological Conditions Network and provided the necessary funding to support it."Michelle Tennyson, PHA Assistant Director and Chair of the Neurological Conditions Network, said: "This detailed engagement exercise was undertaken to get the views and quality of life experiences of those affected by these conditions. We tried to ensure everyone who wanted to contribute could, by providing support through helplines, the internet and face-to-face events. I am honoured that so many people have trusted us with their experiences to help us make a difference and was privileged to be invited into the home of Beth and Arthur McCune for the same reason."The recommendations cover a range of conditions and their implementation will need cooperation and action from professionals, service users, voluntary organizations and others, across many sectors and agencies. The network is looking forward to delivering on these challenging new ways of working to improve the lives of all those affected by neurological conditions."The workshop attracted service users and carers along with delegates from across Northern Ireland's community, voluntary and statutory sectors.If you have a neurological condition, or care for someone who does, and want to share your experiences, please go to: www.publichealth.hscni.net/ncnsurveyYou can also contact Julie Mawhinney, Tel: 028 9032 1313.

Quality Standards for Services Promoting Mental and Emotional Wellbeing and Suicide Prevention

These standards will apply to all organisations providing mental & emotional wellbeing and suicide prevention services which are funded by the PHA.

Magnetic resonance stress tagging in ischemic heart disease.

High-dose dobutamine magnetic resonance stress testing has been shown to be superior to dobutamine stress echocardiography for diagnosis of coronary artery disease (CAD). We determined the feasibility of quantitative myocardial tagging during low- and high-dose dobutamine stress and tested the ability of global systolic and diastolic quantitative parameters to identify patients with significant CAD. Twenty-five patients suspected of having significant CAD were examined with a standard high-dose dobutamine/atropine stress magnetic resonance protocol (1.5-T scanner, Philips). All patients underwent invasive coronary angiography as the standard of reference for the presence (n = 13) or absence (n = 12) of significant CAD. During low-dose dobutamine stress, systolic (circumferential shortening, systolic rotation, and systolic rotation velocity) and diastolic (velocity of circumferential lengthening and diastolic rotation velocity) parameters changed significantly in patients without CAD (all P < 0.05 vs. rest) but not in patients with CAD. Identification of patients without and with CAD during low-dose stress was possible using the diastolic parameter of "time to peak untwist." At high-dose stress, none of the global systolic or diastolic parameters showed the potential to identify the presence of significant CAD. With myocardial tagging, a quantitative analysis of systolic and diastolic function was feasible during low- and high-dose dobutamine stress. In our study, the diastolic parameter of time to peak untwist as assessed during low-dose dobutamine stress was the most promising global parameter for identification of patients with significant CAD. Thus quantitative myocardial tagging may become a tool that reduces the need for high-dose dobutamine stress.

Stress radiography and posterior pathological laxity of knee: comparison between two different techniques.

Stress radiographs have been recommended in order to obtain a better objective quantification of abnormal compartment knee motion. This tool has showed to be superior in quantifying a posterior cruciate ligament (PCL) lesion compared to clinical or arthrometer evaluation. Different radiographic techniques have been described in literature to quantify posterior pathological laxity. In this study we evaluated the total amount of posterior displacement (PTD) and side to side difference (SSD), before and after surgical reconstruction of PCL or PCL and posterolateral complex (PLC), using two different stress radiography techniques (Telos stress and kneeling view). Twenty patients were included in this study. We found a statistical significant difference about both total PTD and SSD among the two techniques preoperatively and at follow-up, with greatest values occurring using the kneeling view. Although stress radiographies has been introduced to allow an objective quantification of laxity in ligamentous injured knee, we believe that further studies on a large numbers of subjects are required to define the relationship between PTD values, measured with stress knee radiography, particularly using kneeling view, and ligamentous knee injury, in order to obtain a real useful tool in the decision making process, as well as to evaluate the outcome after ligamentous surgery.

Adult attachment representations predict cortisol and oxytocin responses to stress.

There are many factors contributing to individual variations in the response to stressful experiences. The present study evaluated the patterns of stress responses according to attachment representations in 28 adults from a community sample, plus 46 subjects expected to be particularly sensitive to stress, having been exposed during childhood and/or adolescence to traumatizing events such as abuse or potentially lethal illnesses. Subjects were given the Adult Attachment Interview, which provides attachment classifications, and the Trier Social Stress Test (TSST), involving an experimental psychosocial challenge. Subjective responses to the TSST, as well as saliva samples (assayed for cortisol) and blood plasma samples (assayed for ACTH and oxytocin) were collected before, during and after the stress procedure. The stress responses presented specific patterns according to attachment classifications. Subjects with an autonomous attachment classification reported relatively low subjective stress, they presented a moderate response of the hypothalamic-pituitary-adrenal (HPA) axis (ACTH and cortisol), and a high level of oxytocin. Subjects with a dismissing classification reported a moderate subjective stress, they presented an elevated response of the HPA axis, and moderate levels of oxytocin. Subjects with a preoccupied classification presented moderate levels of subjective stress, and of HPA response, and a relatively low level of oxytocin. Finally, subjects with an unresolved classification reported elevated subjective stress; they presented a suppressed HPA response, and moderate levels of oxytocin. These data support the notion that attachment representations may affect stress responses, and suggest a specific role of oxytocin in both the attachment system and the stress system.

Promoting young people's social and emotional wellbeing in secondary education.

This guidance is for all those who have a responsibility for the social and emotional wellbeing of young people in secondary education. This includes teachers, support staff, governors and professionals with public health as part of their remit working in education (including the independent sector), local authorities, the NHS and the wider public, voluntary and community sectors. It focuses on interventions to support all young people aged 11-19 who attend any education establishment. Social and emotional wellbeing includes being happy, confident and in control, with the ability to solve and cope with problems and have good relationships with other people. The six recommendations cover: strategy, the key principles and conditions, working in partnership with parents, families and young people, the curriculum, and training and professional development. They include: â?¢ Secondary education establishments should have access to the specialist skills, advice and support they require. â?¢ Practitioners should have the knowledge, understanding and skills they need to develop young peopleâ?Ts social and emotional wellbeing. â?¢ Secondary education establishments should provide a safe environment which nurtures and encourages young peopleâ?Ts sense of self-worth, reduces the threat of bullying and violence and promotes positive behaviour. â?¢ Social and emotional skills education should be tailored to the developmental needs of young people.This resource was contributed by The National Documentation Centre on Drug Use.

Oxidative stress activation of miR-125b is part of the molecular switch for Hailey-Hailey disease manifestation.

Hailey-Hailey disease (HHD) is an autosomal dominant disorder characterized by suprabasal cutaneous cell separation (acantholysis) leading to the development of erosive and oozing skin lesion. Micro RNAs (miRNAs) are endogenous post-transcriptional modulators of gene expression with critical functions in health and disease. Here, we evaluated whether the expression of specific miRNAs may play a role in the pathogenesis of HHD. Here, we report that miRNAs are expressed in a non-random manner in Hailey-Hailey patients. miR-125b appeared a promising candidate for playing a role in HHD manifestation. Both Notch1 and p63 are part of a regulatory signalling whose function is essential for the control of keratinocyte proliferation and differentiation and of note, the expression of both Notch1 and p63 is downregulated in HHD-derived keratinocytes. We found that both Notch1 and p63 expression is strongly suppressed by miR-125b expression. Additionally, we found that miR-125b expression is increased by an oxidative stress-dependent mechanism. Our data suggest that oxidative stress-mediated induction of miR-125b plays a specific role in the pathogenesis of HHD by regulating the expression of factors playing an important role in keratinocyte proliferation and differentiation.

Role of oxidative stress in plasticity of Dendritic cells

Dendritic cells (DCs) are antigen presenting cells with an unique ability to induce primary immune responses. Different DCs subsets with an intrinsic capacity to polarise Tcells have been described: myeloid (Th1) and lymphoid (Th2). Plasticity is defined as DCs capacity to polarise T cells independent of the DCs origin. We investigated the potential role played by oxidants such as superoxide anion (·O2-), in the plasticity of DCs, measured by the induction of a specific DCs subset, cytokine release and antigen presentation. Furthermore, we are interested in the amplification of immune response analysed by the exosomes production after oxidative stress and LPS stimulation. Recently, we have demonstrated that exposure of cells to superoxide anions resulted in the activation of DC2 profile. To analyse the role of oxidative stress in DCs subsets, we used BDCA-1 and BDCA-2 antibodies, which identify myeloid and plasmacytoid DCs respectively. Freshly isolated monocytes have shown to be BDCA-1-, but BDCA-2+ populations. During 6 days culture up-regulation of BDCA-1, but a down-regulation of BDCA-2 were observed, giving a clear myeloid population. When DC were stimulated with superoxide anions or LPS, we have observed that both down regulate the expression of BDCA-1 when compared to immature DC. Antigen presentation was markedly altered according to the periodicity used, and antigens and oxidants exposures. Using DCs trapped in collagen "matrix" after LPS activation we were able to quantify DCs-exosomes (small membrane vesicles ~50-100 nm in diameter) by reconstruction pictures in three dimensions. Using double vital staining we have found that exosomes from activated DCs can fuse with the membrane of resting DCs. Understanding the capacity of DCs to integrate external signals we will be able to unravel and control Tcells-polarisation triggering a specific immune response or tolerance. We will be able also to understand the amplification role of DCs-exosomes in remote not yet activated DCs.

Moderate exercise blunts oxidative stress induced by normobaric hypoxic confinement

PURPOSE: Both acute hypoxia and physical exercise are known to increase oxidative stress. This randomized prospective trial investigated whether the addition of moderate exercise can alter oxidative stress induced by continuous hypoxic exposure. METHODS: Fourteen male participants were confined to 10-d continuous normobaric hypoxia (FIO2 = 0.139 +/- 0.003, PIO2 = 88.2 +/- 0.6 mm Hg, approximately 4000-m simulated altitude) either with (HCE, n = 8, two training sessions per day at 50% of hypoxic maximal aerobic power) or without exercise (HCS, n = 6). Plasma levels of oxidative stress markers (advanced oxidation protein products [AOPP], nitrotyrosine, and malondialdehyde), antioxidant markers (ferric-reducing antioxidant power, superoxide dismutase, glutathione peroxidase, and catalase), nitric oxide end-products, and erythropoietin were measured before the exposure (Pre), after the first 24 h of exposure (D1), after the exposure (Post) and after the 24-h reoxygenation (Post + 1). In addition, graded exercise test in hypoxia was performed before and after the protocol. RESULTS: Maximal aerobic power increased after the protocol in HCE only (+6.8%, P < 0.05). Compared with baseline, AOPP was higher at Post + 1 (+28%, P < 0.05) and nitrotyrosine at Post (+81%, P < 0.05) in HCS only. Superoxide dismutase (+30%, P < 0.05) and catalase (+53%, P < 0.05) increased at Post in HCE only. Higher levels of ferric-reducing antioxidant power (+41%, P < 0.05) at Post and lower levels of AOPP (-47%, P < 0.01) at Post + 1 were measured in HCE versus HCS. Glutathione peroxidase (+31%, P < 0.01) increased in both groups at Post + 1. Similar erythropoietin kinetics was noted in both groups with an increase at D1 (+143%, P < 0.01), a return to baseline at Post, and a decrease at Post + 1 (-56%, P < 0.05). CONCLUSIONS: These data provide evidence that 2 h of moderate daily exercise training can attenuate the oxidative stress induced by continuous hypoxic exposure.

Insufficient coping behavior under chronic stress and vulnerability to psychiatric disorders

Epidemiological data indicate that 75% of subjects with major psychiatric disorders have their onset in the age range of 17-24 years. An estimated 35-50% of college and university students drop out prematurely due to insufficient coping skills under chronic stress, while 85% of students receiving a psychiatric diagnosis withdraw from college/university prior to the completion of their education. In this study we aimed at developing standardized means for identifying students with insufficient coping skills under chronic stress and at risk for mental health problems. A sample of 1,217 college students from 3 different sites in the U.S. and Switzerland completed 2 self-report questionnaires: the Coping Strategies Inventory "COPE" and the Zurich Health Questionnaire "ZHQ" which assesses "regular exercises", "consumption behavior", "impaired physical health", "psychosomatic disturbances", and "impaired mental health". The data were subjected to structure analyses by means of a Neural Network approach. We found 2 highly stable and reproducible COPE scales that explained the observed inter-individual variation in coping behavior sufficiently well and in a socio-culturally independent way. The scales reflected basic coping behavior in terms of "activity-passivity" and "defeatism-resilience", and in the sense of stable, socio-culturally independent personality traits. Correlation analyses carried out for external validation revealed a close relationship between high scores on the defeatism scale and impaired physical and mental health. This underlined the role of insufficient coping behavior as a risk factor for physical and mental health problems. The combined COPE and ZHQ instruments appear to constitute powerful screening tools for insufficient coping skills under chronic stress and for risks of mental health problems.

Stress au travail et santé : situation chez les indépendants : synthèse et recommandations

Dans le cadre de l'activité professionnelle, des facteurs de stress d'ordre psychologique, social, et liés à l'organisation du travail, peuvent induire des réponses physiologiques et comportementales impliquées dans la survenue de pathologies comme les maladies cardiovasculaires, les troubles de la santé mentale et les troubles musculosquelettiques.Le Régime social des indépendants (RSI) a sollicité l'Inserm afin de disposer d'un bilan des connaissances sur le stress d'origine professionnelle chez les travailleurs indépendants et ses répercussions sur la santé.Regroupant à la fois des compétences en biologie, psychologie, sociologie et économie de la santé, cette expertise collective présente les modèles et les mécanismes explicatifs mettant en relation le stress au travail et les principales pathologies.Les stratégies de prévention individuelle et collective qui se développent dans le milieu des travailleurs salariés peuvent-elles être adaptées aux travailleurs indépendants ?

Individualiser la thérapie d'exposition pour le stress post-traumatique: le cas de Caroline

Dans la thérapie de l'état de stress post-traumatique chronique (PTSD), l'Exposition Prolongée (PE) à des stimuli associes à une expérience d'origine traumatique est considérée comme une méthode de traitement de pointe. Notre étude de cas, basée sur l'utilisation du manuel de Foa et Rothbaum (1998), concerne Caroline, une patiente adulte victime d'abus sexuels dans l'enfance, traitée en 40 séances, sur une durée d'une année. En complément, nous avons la technique de l'«Analyse des Plans» de Caspar (1995, 2007) pour la formulation de cas individualisée et la planification du traitement, selon le concept de Caspar de la Relation Thérapeutique Orientée sur les Motifs (MOTR). Le traitement a été très efficace, comme l'attestent les mesures quantitatives standardisées, les changements dans les schémas de comportements, ainsi que son compte rendu subjectif. Une analyse du processus thérapeutique illustre l'importance d'une combinaison de procédures basées sur un manuel avec des formulations et interventions de cas individuels. Le cas est discute dans le contexte de l'amélioration du traitement cognitivo-comportemental du PTSD.
