Gender-related psychological and behavioural correlates of pubertal timing in a national sample of Swiss adolescents.

The potential consequences of early and late puberty on the psychological and behavioural development of the adolescent are not well known. This paper presents focused analyses from the Swiss SMASH study, a self-administered questionnaire survey conducted among a representative sample of 7488 adolescents from 16 to 20 years old. Data from participants reporting early or late timing of puberty were compared with those reporting average timing of maturation. Early maturing girls reported a higher rate of dissatisfaction with body image (OR=1.32) and functional symptoms (OR=1.52) and reported engaging in sexual activity more often (OR=1.93). Early maturing boys reported engaging in exploratory behaviours (sexual intercourse, legal and illegal substance use) at a significantly higher rate (OR varying between 1.4 and 1.99). Both early and late maturing boys reported higher rates of dysfunctional eating patterns (OR=1.59 and 1.38, respectively), victimisation (OR=1.61 and 1.37, respectively) and depressive symptoms (OR=2.11 and 1.53, respectively). Clinicians should take into account the pubertal stage of their patients and provide them, as well as their parents, with appropriate counselling in the field of mental health and health behaviour.

Termination of pregnancy among teenagers - why more surgical terminations?

Introduction: In 2012, a study by K. Chatziioannidou and S-C. Renteria showed that teenagers chose to undergo a surgical termination of pregnancy (TOP) more often than a medical TOP (mifepristone followed by misoprostol) when they decided to terminate a pregnancy. It also showed that the teenagers' choice for a medical versus surgical method is inversely proportional to the adults' choice although the efficiency of the medical method showed even better results for teenagers than for adults. According to the hypothesis made, the reasons for this choice might be influenced by the following facts: (i) the belated call to make an appointment, the medical procedure not being available after 9 weeks of gestation; (ii) the imperative request for confidentiality; (iii) the beliefs and subjective appreciation of the medical staff. Objectives: The aim of this retrospective and qualitative study is to analyse the reasons why, in case of a TOP, teenagers chose the surgical method more often than their adult counterparts. Material: (i) All teenagers who were admitted for an abortive procedure during 2011 in the in- or outpatient ward. (ii) The professional team (midwives and sexual and reproductive counsellors) in charge in the case of a TOP request. Methods: The information about the patient's history and the biopsycho- social data was retrieved from the patient files filled out by midwives and sexual and reproductive health counsellors during the first appointment for a TOP request or during its process. The professionals' appreciation was evaluated by means of a semi-structured questionnaire. Results: Concerning the choice of the method for a pregnancy termination, the results of our research show that: (i) Out of 47 teenagers, 27 chose the surgical method and 17 the medical method. (ii) Three had a second trimester abortion (which includes use of the medical method). (iii) Fifteen teenagers out of the 27 who chose a surgical method consulted between the 9th and 14th weeks of amenorrhoea and therefore did not have any other choice. The reasons for their 'late arrival' will be explained in detail. The 12 teenagers who arrived before the 8th week of amenorrhoea and chose to undertake abortion by suction & curettage under general anaesthesia did it for the following reasons: (i) Four were afraid of bleeding and pain. (ii) Five thought that the organisation of the surgical procedure was easier. (iii) Two did not trust the abortion pill. (iv) One was taken to her mother's gynaecologist where she had a D&C. Confidentiality was requested nine times out of 27 when choosing the surgical method, and six times out of 17 when choosing the medical method. Therefore, although confidentiality concerns a third of the teenagers' pregnancy termination requests, it does not seem to be a significant element for the choice of the method. As for the subjective appreciation of the professionals, the first results of the discussions seem to show that teenagers were reluctant or resistant towards the medical method. Conclusion: This study shows that the reasons why teenagers still prefer the use of the surgical over the medical method compared to adults, seem to include the late request for an appointment, fear of pain and bleeding and organisational issues. Confidentiality does not seem to greatly influence the teenagers' choice. Nonetheless, medical professionals seem to favour the suction curettage procedure performed under anesthesia because they associate young age with vulnerability and psychological frailty and consequently diminished ability to cope with pain and emotional distress during the medical procedures.

The Effects of Multifactorial Fall Prevention on the Psychological Risk Factors of Falling

Psychological factors, such as depression or depressive symptoms and fear of falling are linked to falls among the aged. According to previous studies, they may increase the risk of falls and injurious falls. In addition, depression or a high amount of depressive symptoms and fear of falling may hinder participation in preventive activities. Despite the severe consequences of both conditions and their high prevalence among the aged, they have rarely been studied in the context of fall prevention. The study aimed to assess the effects of multifactorial fall prevention on the psychological risk factors of falling (depressive symptoms and fear of falling) among the community-dwelling aged at increased risk of falling. In addition, it aimed to determine factors predicting high adherence to preventive activities. Volunteers aged 65 or over, who had fallen during the year previous to randomisation were recruited. Participants (n=591) were randomised into an intervention or a control group. The intervention group received a multifactorial fall prevention programme including geriatric assessment, individual guidance on fall and fracture prevention, group- and home-based physical exercise, psychosocial group activities, lectures and home hazards assessment. The control group had a one-time counselling on fall and fracture prevention. The data on psychological risk factors of falling were collected by self-rated questionnaires. Multifactorial fall prevention was not effective in reducing depressive symptoms or fear of falling compared to one-time counselling in the total sample. However, in subgroup analyses, depressive symptoms reduced statistically significantly more among the men and older participants of the intervention group compared to the control group. Female gender, high physical and cognitive abilities and low self-perceived probability of falling were independent predictors of higher adherence in organised activities. In conclusion, few psychological benefits were gained during this multifactorial fall prevention trial. More attention should be focused on adherence, especially among the aged with functional disabilities.

Neuroendocrine regulation and central dopamine (DA) systems in physical and psychological stress

Physical and psychological stress cause different patterns of changes in the fluorescence intensity of nigral and tuberoinfundibular DA neurons which point to changes in neuronal activity. In order to investigate possible interactions between alpha-MSH (alpha-melanotropin) and DA systems in stress, systemic and intraventricular injections of antiserum against alpha-MSH were made. The functional state of DA neurons was assessed by histochemical microfluorimetry and hormone levels were measured by radioimmunossay. Antiserum against alpha-MSH was found to affect the functional state of DA neurons, but only thorugh the intravenous route. Under physical stress i.v. injection of antiserum against alpha-MSH was accompanied by elevated levels of activity of the DA neurons of the substantia nigra. An intraventricular injection of the same antiserum was ineffective. In psychological stress, an effect was again seen only after intravenous injection of antiserum against alpha-MSH. In this situation, the activity in DA cell groups of the substantia nigra, ventral tegmental area and tubero-infundibular system was increased after antiserum injection. Possible influences from manipulations were checked; certain effects which depended upon experimental situation were noted. Our data suggest a modulatory influence of circulating alpha-MSH on the functional state of central DA systems.

Induced normothermia attenuates cerebral metabolic distress in patients with aneurysmal subarachnoid hemorrhage and refractory Fever.

BACKGROUND AND PURPOSE: The purpose of this study was to analyze whether fever control attenuates cerebral metabolic distress after aneurysmal subarachnoid hemorrhage (SAH). METHODS: Eighteen SAH patients, who underwent intracranial pressure (ICP) and cerebral microdialysis monitoring and were treated with induced normothermia for refractory fever (body temperature >or=38.3 degrees C, despite antipyretics), were studied. Levels of microdialysate lactate/pyruvate ratio (LPR) and episodes of cerebral metabolic crisis (LPR >40) were analyzed during fever and induced normothermia, at normal and high ICP (>20 mm Hg). RESULTS: Compared to fever, induced normothermia resulted in lower LPR (40+/-24 versus 32+/-9, P<0.01) and a reduced incidence of cerebral metabolic crisis (13% versus 5%, P<0.05) at normal ICP. During episodes of high ICP, induced normothermia was associated with a similar reduction of LPR, fewer episodes of cerebral metabolic crisis (37% versus 8%, P<0.01), and lower ICP (32+/-11 versus 28+/-12 mm Hg, P<0.05). CONCLUSIONS: Fever control is associated with reduced cerebral metabolic distress in patients with SAH, irrespective of ICP.

Personality traits, behavioral and psychological symptoms and cognitive decline in patients at an early stage of Alzheimer's disease

The aim of this doctoral thesis was to study personality characteristics of patients at an early stage of Alzheimer's disease (AD), and more specifically to describe personality and its changes over time, and to explore its possible links with psychological and symptoms (BPS) and cognitive level. The results were compared to those of a group of participants without cognitive disorder through three empirical studies. In the first study, the findings showed significant personality changes that follow a specific trend in the clinical group. The profil of personality changes showed an increase in Neuroticism and a decrease in Extraversion, Openess to experiences, and Conscientiousness over time. The second study highlighted that personality and BPS occur early in the cours of AD. Recognizing them as possible precoce signs of neurodegeneration may prove to be a key factor for early detection and intervention. In the third study, a significant association between personality changes and cognitive status was observed in the patients with incipient AD. Thus, changes in Neuroticism and Conscientiousness were linked with cognitive deterioration, whereas decreased Openness to experiences and Conscientiousness over time predicted loss of independence in daily functioning. Other well-known factors such as age, education level or civil status were taken into account to predict cognitive decline. The three studies suggested five important implications: (1) cost-effective screening should take into account premorbid and specific personality changes; (2) psycho-educative interventions should provide information on the possible personality changes and BPS that may occur at the beginning of the disease; (3) using personality traits alongside other variables in the future studies on prevention might help to better understand AD's etiology; (4) individual treatment plans (psychotherapeutic, social, and pharmacological) might be adapted to the specific changes in personality profiles; (5) more researches are needed to study the impact of social-cultural and lifestyle variables on the development of AD.

Validation of the spiritual distress assessment tool in older hospitalized patients.

ABSTRACT:¦BACKGROUND: The Spiritual Distress Assessment Tool (SDAT) is a 5-item instrument developed to assess unmet spiritual needs in hospitalized elderly patients and to determine the presence of spiritual distress. The objective of this study was to investigate the SDAT psychometric properties.¦METHODS: This cross-sectional study was performed in a Geriatric Rehabilitation Unit. Patients (N = 203), aged 65 years and over with Mini Mental State Exam score ≥ 20, were consecutively enrolled over a 6-month period. Data on health, functional, cognitive, affective and spiritual status were collected upon admission. Interviews using the SDAT (score from 0 to 15, higher scores indicating higher distress) were conducted by a trained chaplain. Factor analysis, measures of internal consistency (inter-item and item-to-total correlations, Cronbach α), and reliability (intra-rater and inter-rater) were performed. Criterion-related validity was assessed using the Functional Assessment of Chronic Illness Therapy-Spiritual well-being (FACIT-Sp) and the question "Are you at peace?" as criterion-standard. Concurrent and predictive validity were assessed using the Geriatric Depression Scale (GDS), occurrence of a family meeting, hospital length of stay (LOS) and destination at discharge.¦RESULTS: SDAT scores ranged from 1 to 11 (mean 5.6 ± 2.4). Overall, 65.0% (132/203) of the patients reported some spiritual distress on SDAT total score and 22.2% (45/203) reported at least one severe unmet spiritual need. A two-factor solution explained 60% of the variance. Inter-item correlations ranged from 0.11 to 0.41 (eight out of ten with P < 0.05). Item-to-total correlations ranged from 0.57 to 0.66 (all P < 0.001). Cronbach α was acceptable (0.60). Intra-rater and inter-rater reliabilities were high (Intraclass Correlation Coefficients ranging from 0.87 to 0.96). SDAT correlated significantly with the FACIT-Sp, "Are you at peace?", GDS (Rho -0.45, -0.33, and 0.43, respectively, all P < .001), and LOS (Rho 0.15, P = .03). Compared with patients showing no severely unmet spiritual need, patients with at least one severe unmet spiritual need had higher odds of occurrence of a family meeting (adjOR 4.7, 95%CI 1.4-16.3, P = .02) and were more often discharged to a nursing home (13.3% vs 3.8%; P = .027).¦CONCLUSIONS: SDAT has acceptable psychometrics properties and appears to be a valid and reliable instrument to assess spiritual distress in elderly hospitalized patients.

Traumatismes précoces et réponses de stress, leur association aves la santé mentale, l'attachement et l'ocytocine

Lorsqu'un individu est confronté à une situation stressante, une des réponses les plus saillantes est l'activation de l'axe HPA, caractérisée par le déclenchement d'un taux élevé de glucocorticoïdes dans le sang. De manière générale, cette réponse hormonale est adaptative et elle a pour but la mobilisation des ressources physiques et cognitives de l'individu pour une action spécifique (Axelrod & Reisine, 1984; Chrousos & Gold, 1992; N. M. Kaplan, 1988; McEwen, 2004). Cependant, lorsque une personne est confrontée très tôt dans son développement, et de manière répétée, à des situations de stress, cette réponse physiologique peut s'altérer, devenir inadaptée (Anand, 1993; Bremner et al., 1995; Meaney et al., 1996; Mirescu, Peters, & Gould, 2004; Plotsky & Meaney, 1993; Sapolsky, 2000) et être associée à des troubles cognitifs (McEwen & Sapolsky, 1995) et émotionnels (McEwen, 2000). A l'âge adulte, le résultat de ces altérations psychoneuroendocriniennes se traduit au cours de l'activation de l'axe HPA et elles sont visibles lors de situations de stress moins intenses (Graham, Heim, Goodman, Miller, & Nemeroff, 1999; Mirescu et al., 2004; Stam, Bruijnzeel, & Wiegant, 2000; A. Taylor, Fisk, & Glover, 2000). La dysregulation de l'axe HPA semble représenter un facteur de vulnérabilité lié à des dysfonctionnements psychiques et physiologiques chez les adultes (Heim, Ehlert, & Hellhammer, 2000; Heim & Nemeroff, 1999; Heim, Newport, Mletzko, Miller, & Hemeroff, 2008). Cependant, des facteurs de protection peuvent influencer à leur tour ces vulnérabilités. La littérature, basée sur des études translationnelles (animaux, humains), converge vers le postulat selon lequel la dimension relationnelle apportée par l'environnement est fondamentale dans le développement des vulnérabilités physiologiques et psychiques du sujet. Dans ce sens, les relations d'attachement ont été particulièrement étudiées. A l'âge adulte, par exemple, la qualité des représentations d'attachement semble influencer directement l'expression de gènes impliqués dans les réponses hormonales de stress (Biagini, Pich, Carani, Marrama, & Agnati, 1998; Caldji, Diorio, & Meaney, 2000; Dallman, 2000; De Kloet, Rosenfeld, Van Eekelen, Sutanto, & Levine, 1988; Rincon-Cortes & Sullivan, 2014; Romeo, Tang, & Sullivan, 2009; van Oers, de Kloet, Whelan, & Levine, 1998), illustrant ainsi une perspective épigénétique. Traumatismes précoces et réponses de stress, leur association avec la santé mentale, l'attachement et l'ocytocine Deux objectifs principaux définissent ce travail de doctorat. Le premier est de comprendre comment un événement à portée traumatique, qui a eu lieu pendant la période périnatale, l'enfance ou l'adolescence, peut s'inscrire au niveau physiologique (axe hypotalamico- hypophysaire-surrénalien - axe HPA), au niveau psychopathologique ou encore au niveau de la régulation émotionnelle au cours de l'âge adulte. A ce propos, nous avons évalué les réponses physiologiques (telles que le Cortisol, l'ACTH et l'ocytocine), la présence de psychopathologies (relatives à l'axe I du DSM-IV) et les réponses émotionnelles (telles que la perception au stress) au cours d'une situation de stress de nature psychosociale, induite en laboratoire. Le deuxième objectif de ce travail est de savoir si les représentations d'attachement peuvent médiatiser ces effets, chez des individus exposés à différents événements à portée traumatique. Dans ce but, trois populations ont été considérées. La première est relative à des jeunes adultes nés grands prématurés ; la deuxième, concerne des femmes adultes ayant vécu un ou plusieurs abus sexuels au cours de leur enfance ou de leur adolescence et enfin la troisième est constituée de personnes adultes qui ont survécu à une maladie grave (cancer) pendant leur enfance ou leur adolescence. Enfin, ces trois populations sont comparées à des groupes contrôle. La prise en considération de différents types de traumatismes a permis de relever : premièrement, qu'un événement à portée traumatique de nature différente, peut influencer de manière semblable les structures neuronales, par exemple l'hypocortisolémie ; deuxièmement, qu'un dysfonctionnement de l'axe HPA n'aboutit pas nécessairement à la présence de signes de souffrance mentale ; enfin, des effets protecteurs ont été mis en évidence. Ces facteurs sont sous-tendus, d'un point de vue psychologique, par les représentations d'attachement et, d'un point de vue physiologique, par la sécrétion d'ocytocjne périphérique. Traumatismes précoces et réponses de stress, leur association avec la santé mentale, l'attachement et l'ocytocine -- When an individual is faced by a stressful situation, one of the most notable responses is the activation of the HPA axis, which is characterized by a heightened level of glucocortisoids in the blood. In general, this is an adaptive hormonal response which prepares the individual both physically and cognitively for a specific action (Axelrod & Reisine, 1984; Chrousos & Gold, 1992; N. M. Kaplan, 1988; McEwen, 2004). However, should a person be confronted to stressful situations very early and repeatedly in their development, this physiologic response may be altered and become maladapted (Anand, 1993; Bremner et al., 1995; Meaney et al., 1996; Mirescu et al., 2004; Plotsky & Meaney, 1993; Sapolsky, 2000) which can be associated to emotional (McEwen, 2000) and cognitive disorders(McEwen & Sapolsky, 1995). Throughout adulthood, the result of these psychoneuroendocrine alterations affects the activation of the HPA axis and are noticeable during less intense stressful situations (Graham et al., 1999; Mirescu et al., 2004; Stam et al., 2000; A. Taylor et al., 2000). HPA axis dysregulation appears to represent a factor of vulnerability linked to psychological and physical disorders in adults (Heim, Ehlert, et al., 2000; Heim & Nemeroff, 1999; Heim, Newport, et al., 2008). Nonetheless, these vulnerabilities may be influenced by further protection factors. The literature, based on translational studies (animals and humans), suggests that relationships formed in the context of the individual's environment are fundamental in the development of their physiological and psychological vulnerabilities. Thus, attachment relationships have been particularly studied. In adulthood, for example, the quality of attachment representations appear to influence directly the expression of genes involved in the hormonal responses to stress (Biagini et al., 1998; Caldji et al., 2000; Dallman, 2000; De Kloet et al., 1988; Rincon-Cortes & Sullivan, 2014; Romeo et al., 2009; van Oers et al., 1998). With the goal to study these dimensions, two principal objectives define these doctoral study. The first is to understand how an event considered to be traumatic, which took place during early infancy, infancy, or adolescence, could influence physiology (HPA axis), psychopathology or emotional regulation during adulthood. Therefore we have evaluated the presence of psychopathologies (relative to axis I of the DSM), physiological responses (such as Cortisol, ACTH and oxytocin) and emotional responses (such as perception of stress) throughout a psychosocial stress situation, conducted in a laboratory setting. The second objective of this study is to understand if attachment representations can mediate these effects, in individuals exposed to three different types of traumatic events. Therefore, three populations have been considered. The first is young adults who were born prematurely; the second concerns adult women who have suffered sexual abuse, on one or more occasions, during their childhood or adolescence; finally the third group is constituted of people who have survived a grave childhood illness. These populations were all compared to control groups. The consideration of different types of traumatic events has demonstrated, firstly, that different events which are considered to be traumatic can similarly influence neuronal structures, for example hypocortisolism. Secondly, that an HPA axis disorder does not necessarily lead to the presence of mental signs of distress, as is the case for those born very prematurely. Finally, protective effects were demonstrated, distinctively from a psychological point of view, by attachment representations and furthermore by peripheral oxytocin secretion from a physiological perspective.

Psychosexual development in men with congenital hypogonadotropic hypogonadism on long-term treatment: a mixed methods study.

INTRODUCTION: Congenital hypogonadotropic hypogonadism (CHH) is a rare, genetic, reproductive endocrine disorder characterized by absent puberty and infertility. Limited information is available on the psychosocial impact of CHH and psychosexual development in these patients. AIM: The aim of this study was to determine the impact of CHH on psychosexual development in men on long-term treatment. METHODS: A sequential mixed methods explanatory design was used. First, an online survey (quantitative) was used to quantify the frequency of psychosexual problems among CHH men. Second, patient focus groups (qualitative) were conducted to explore survey findings in detail and develop a working model to guide potential nursing and interdisciplinary interventions. MAIN OUTCOME MEASURES: Patient characteristics, frequency of body shame, difficulty with intimate relationships, and never having been sexually active were assessed. Additionally, we collected subjective patient-reported outcomes regarding the impact of CHH on psychological/emotional well-being, intimate relationships, and sexual activity. RESULTS: A total of 101 CHH men on long-term treatment (>1 year) were included for the analysis of the online survey (mean age 37 ± 11 years, range 19-66, median 36). Half (52/101, 51%) of the men had been seen at a specialized academic center and 37/101 (37%) reported having had fertility-inducing treatment. A high percentage of CHH men experience psychosexual problems including difficulty with intimate relationships (70%) and body image concerns/body shame (94/101, 93%), and the percentage of men never having been sexually active is five times the rate in a reference group (26% vs. 5.4%, P < 0.001). Focus groups revealed persisting body shame and low self-esteem despite long-term treatment that has lasting impact on psychosexual functioning. CONCLUSIONS: CHH men frequently experience psychosexual problems that pose barriers to intimate relationships and initiating sexual activity. These lingering effects cause significant distress and are not ameliorated by long-term treatment. Psychosexual assessment in CHH men with appropriate psychological support and treatment should be warranted in these patients. Dwyer AA, Quinton R, Pitteloud N, and Morin D.

Virtual milgram : empathic concern or personal distress? Evidence from functional MRI and dispositional measures

One motive for behaving as the agent of another"s aggression appears to be anchored in as yet unelucidated mechanisms of obedience to authority. In a recent partial replication of Milgram"s obedience paradigm within an immersive virtual environment, participants administered pain to a female virtual human and observed her suffering. Whether the participants" response to the latter was more akin to other-oriented empathic concern for her well-being or to a self-oriented aversive state of personal distress in response to her distress is unclear. Using the stimuli from that study, this event-related fMRI-based study analysed brain activity during observation of the victim in pain versus not in pain. This contrast revealed activation in pre-defi ned brain areas known to be involved in affective processing but not in those commonly associated with affect sharing (e.g., ACC and insula). We then examined whether different dimensions of dispositional empathy predict activity within the same pre-defi ned brain regions: While personal distress and fantasy (i.e., tendency to transpose oneself into fi ctional situations and characters) predicted brain activity, empathic concern and perspective taking predicted no change in neuronal response associated with pain observation. These exploratory fi ndings suggest that there is a distinct pattern of brain activity associated with observing the pain-related behaviour of the victim within the context of this social dilemma, that this observation evoked a self-oriented aversive state of personal distress, and that the objective"reality" of pain is of secondary importance for this response. These fi ndings provide a starting point for experimentally more rigorous investigation of obedience.

On the Adoption of Partial Least Squares in Psychological Research: Caveat Emptor

The partial least squares technique (PLS) has been touted as a viable alternative to latent variable structural equation modeling (SEM) for evaluating theoretical models in the differential psychology domain. We bring some balance to the discussion by reviewing the broader methodological literature to highlight: (1) the misleading characterization of PLS as an SEM method; (2) limitations of PLS for global model testing; (3) problems in testing the significance of path coefficients; (4) extremely high false positive rates when using empirical confidence intervals in conjunction with a new "sign change correction" for path coefficients; (5) misconceptions surrounding the supposedly superior ability of PLS to handle small sample sizes and non-normality; and (6) conceptual and statistical problems with formative measurement and the application of PLS to such models. Additionally, we also reanalyze the dataset provided by Willaby et al. (2015; doi:10.1016/j.paid.2014.09.008) to highlight the limitations of PLS. Our broader review and analysis of the available evidence makes it clear that PLS is not useful for statistical estimation and testing.
