Quantifying insufficient coping behavior under chronic stress. A cross-cultural study of 1,303 students from Italy, Spain, and Argentina.

The question of how to quantify insufficient coping behavior under chronic stress is of major clinical relevance. In fact, chronic stress increasingly dominates modern work conditions and can affect nearly every system of the human body, as suggested by physical, cognitive, affective and behavioral symptoms. Since freshmen students experience constantly high levels of stress due to tight schedules and frequent examinations, we carried out a 3-center study of 1,303 students from Italy, Spain and Argentina in order to develop socioculturally independent means for quantifying coping behavior. The data analysis relied on 2 self-report questionnaires: the Coping Strategies Inventory (COPE) for the assessment of coping behavior and the Zurich Health Questionnaire which assesses consumption behavior and general health dimensions. A neural network approach was used to determine the structural properties inherent in the COPE instrument. Our analyses revealed 2 highly stable, socioculturally independent scales that reflected basic coping behavior in terms of the personality traits activity-passivity and defeatism-resilience. This replicated previous results based on Swiss and US-American data. The percentage of students exhibiting insufficient coping behavior was very similar across the study sites (11.5-18.0%). Given their stability and validity, the newly developed scales enable the quantification of basic coping behavior in a cost-efficient and reliable way, thus clearing the way for the early detection of subjects with insufficient coping skills under chronic stress who may be at risk of physical or mental health problems.

Physician behavioral adaptability: A model to outstrip a "one size fits all" approach

Objective: Based on a literature review, we propose a model of physician behavioral adaptability (PBA) with the goal of inspiring new research. PBA means that the physician adapts his or her behavior according to patients' different preferences. The PBA model shows how physicians infer patients' preferences and adapt their interaction behavior from one patient to the other. We claim that patients will benefit from better outcomes if their physicians show behavioral adaptability rather than a "one size fits all" approach. Method: This literature review is based on a literature search of the PsycINFO1 and MEDLINE1 databases. Results: The literature review and first results stemming from the authors' research support the validity and viability of parts of the PBA model. There is evidence suggesting that physicians are able to show behavioral flexibility when interacting with their different patients, that a match between patients' preferences and physician behavior is related to better consultation outcomes, and that physician behavioral adaptability is related to better consultation outcomes. Practice implications: Training of physicians' behavioral flexibility and their ability to infer patients' preferences can facilitate physician behavioral adaptability and positive patient outcomes.

Evaluation of molecular, cellular and behavioral consequences of serotonin 1A receptor deletion

In 1998, three different research groups simultaneously reported increased anxiety-related behavior in tests of conflict in their serotonin 1a (5-HT1a) receptor knockout (KO) line with male mice being more severely affected by 5-HT1a receptor deletion than female KO. Similarly, in the hippocampus, we observed increased dendritic complexity in the stratum radiatum of CA1 pyramidal neurons in male but not in female 5-HT1a receptor KO mice. These observations prompted us to investigate gender- dependent differences of 5-HT1a receptor deletion in hippocampal-related behavioral tasks. Testing our mice in anxiety-related paradigms, we reproduced the original studies showing increased anxiety- related behavior in male 5-HT1a receptor KO mice when compared to male WT mice, but no difference between female 5-HT1a receptor KO and WT mice. Similarly, male 5-HT1a receptor KO mice were impaired in association of aversive stimuli fear conditioning paradigms. We argue that increased dendritic complexity and increased synaptic strength of CA3-CA1 synapses in the stratum radiatum impaired proper signal propagation attributed to overactivation of CA1 pyramidal neurons leading to impaired fear memory of male 5-HT1a receptor KO mice. Similar mechanisms in the ventral hippocampus are likely to have contributed to gender-dependent differences in anxiety-related behavior in our and the original studies from 1998. In this study, we started to shed light on the 5-HT1a receptor downstream signaling pathways involved in dendritogenesis of pyramidal neurons during early postnatal development. We could show that NR2B-containing NMDA receptor during development acts downstream of 5-HT1a receptor and is responsible for increased amount of branching in male 5-HT1a receptor KO mice. Conversely, protein and NR2B mRNA expression was increased in 5-HT1a receptor KO mice at P15. Although the exact signaling cascade of 5-HT1a receptor regulating NR2B-containing NMDA receptor has not been determined, CaMKII is a potential downstream effector to influence transportation and removal of NR2B-containing NMDA receptors to and from the synapse. In contrast, Erk1/2 likely acts downstream of NR2B-containing NMDA receptors and was shown to be sufficient to regulate dendritic branching. Moreover, increased NR2B-containing NMDA receptor mediated cell death via excitotoxicity during development and is likely to be involved in reduced survival of adult born neurons in the hippocampus of 5-HT1a receptor KO male. The convergence of 5-HT1a receptor signaling onto NR2B-containing NMDA receptor signaling enables estrogen to interfere with its downstream pathway via G-protein coupled estrogen receptor 1 activation resulting in normalization of branching and behavior in female 5-HT1a receptor mice. In conclusion, our data strongly suggests a hormone- regulated mechanism that by converging on NR2B-containing NMDA receptor signaling is able to normalize morphology of pyramidal neurons and behavior of female 5-HT1a receptor KO mice. Our findings provide a possible explanation for gender-dependent differences in the occurrence of mental disorders with 5-HT1a receptor abnormalities as a strong predisposing factor. -- En 1998, trois équipes de recherche ont décrit un comportement de type anxieux dans des tests de conflit pour leur souris transgéniques avec une délétion du gène pour le récepteur 5-HT1a de la sérotonine. De plus, les trois groupes rapportent un phénotype plus sévère pour le comportement anxieux chez les souris transgéniques mâles que femelles. Dans l'hippocampe, la région avec la densité de récepteur 5-HT1a la plus élevée dans le télencéphale, nous avons observé dans le stratum radiatum une complexité accrue des arborisations dendritiques des neurones pyramidaux du secteur CA1 chez les souris transgénique mâles mais pas chez les femelles. Cette observation nous a encouragés à initier cette étude sur les différences en fonction du genre utilisant les tests comportementaux en rapport avec les fonctions de l'hippocampe chez les souris déficientes pour le récepteur 5-HT1a.Testant nos souris avec des paradigmes associés à l'anxiété, nous avons reproduit les données originales montrant que les souris transgéniques mâles ont un phénotype plus sévère que les souris mâles sauvages, mais qu'aucune différence n'est observée entre les femelles sauvages et transgéniques. De même, les souris mâles déficientes pour le récepteur 5-HT1a sont handicapées dans les tests de conditionnement au stress avec des stimuli aversifs. Nous faisons l'hypothèse que l'augmentation de la complexité de l'arborisation dendritique et l'augmentation de la force du signal synaptique entres les régions CA3 et CA1 de l'hippocampe dans le stratum radiatum perturbe la propagation du signal nerveux qui conduit à l'hyperactivation des neurones du secteur CA1. Ceci conduit à une mémoire de stress altérée chez les souris mâles déficientes pour le récepteur 5-HT1a. Un mécanisme similaire dans l'hippocampe ventral contribue probablement aux différences en fonction du genre dans les tests pour le comportement de type anxieux qui ont été rapportés dans les études originales de 1998. Les mesures de protéine et de mRNA ont mis en évidence une augmentation de l'expression du récepteur NMDA contenant la sous- unité NR2B dans les souris déficientes pour le récepteur 5-HT1a à P15. Dans les cultures organotypiques d'hippocampe, nous avons commencé à disséquer les messagers secondaires à l'activation du récepteur 5-HT1a qui sont impliqués dans la régulation de la croissance dendritique des neurones pyramidaux pendant la période postnatale précoce. Nous avons démontré que les récepteurs NR2B sont en aval de l'activation du récepteur 5-HT1a et qu'ils sont impliqués dans l'accroissement du nombre de dendrites chez la souris mâle déficiente pour le récepteur 5-HT1a. Bien que la cascade de signalisation du récepteur 5-HT1a pour réguler les récepteurs NMDA contenant le NR2B ne soit pas établie, CaMKII est identifié comme un effecteur potentiel pour altérer le transport du récepteur NMDA à la synapse. D'autre part, Erk1/2 est probablement un messager en aval du NR2B du récepteur NMDA, et a été documenté comme suffisant pour réguler l'arborisation dendritique. L'augmentation de NR2B à la synapse des souris déficientes pour le récepteur 5-HT1a peut conduire à une augmentation de l'excitotoxicité dans les cellules. Nous avons observé une augmentation chez la souris déficiente pour le récepteur 5-HT1a de la mort cellulaire dans des tranches d'hippocampe stimulées, ce qui peut être en relation avec la réduction de la survie des neurones générés dans l'hippocampe de la souris mâle transgénique adulte par rapport à la souris mâle sauvage. De plus, la convergence de la signalisation du récepteur 5-HT1a sur la signalisation de la sous-unité NR2B du récepteur NMDA permet à l'oestrogène d'interférer avec sa voie de signalisation du récepteur de l'oestrogène couplé à une protéine G (GPER-1), ceci permettant à l'oestrogène de réduire la taille de l'arborisation des neurones pyramidaux de CA1 chez la femelle de la souris déficiente pour le récepteur 5-HT1a. En conclusion, nos observations suggèrent fortement qu'un mécanisme hormonal convergeant sur la voie de signalisation de la sous-unité NR2B du récepteur NMDA permet la normalisation de l'exubérance des dendrites des neurones CA1 de l'hippocampe et du comportement des souris femelles déficientes pour le récepteur 5-HT1a. Ceci donne une explication possible pour la différence en fonction du genre dans l'apparition de troubles mentaux avec les variations du récepteur 5-HT1a comme facteur de prédisposition important.

Précarité et problèmes cutanés [Skin problems associated with poor living conditions].

Les personnes vivant dans une situation de précarité sont susceptibles de développer un large éventail de problèmes médicaux et les atteintes cutanées sont très fréquentes. Nous présentons quatre situations cliniques de problèmes cutanés fréquemment retrouvés au sein des populations précaires. Leurs diagnostic et prise en charge précoces sont essentiels pour en prévenir l'ultérieure dissémination dans des contextes de promiscuité. People living in poor conditions are at high risk of developing different medical diseases of which dermatological diseases are very common. We present 4 clinical cases of skin diseases, which are the most prevalent amongst the majority of socially and economically vulnerable patients. Early diagnosis and appropriate treatment are of paramount importance, in order to avoid their spread in close- knit communities where these patients often live.

Delirium in the elderly: Current problems with increasing geriatric age.

Delirium is an acute disorder of attention and cognition seen relatively commonly in people aged 65 yr or older. The prevalence is estimated to be between 11 and 42 per cent for elderly patients on medical wards. The prevalence is also high in nursing homes and long term care (LTC) facilities. The consequences of delirium could be significant such as an increase in mortality in the hospital, long-term cognitive decline, loss of autonomy and increased risk to be institutionalized. Despite being a common condition, it remains under-recognised, poorly understood and not adequately managed. Advanced age and dementia are the most important risk factors. Pain, dehydration, infections, stroke and metabolic disturbances, and surgery are the most common triggering factors. Delirium is preventable in a large proportion of cases and therefore, it is also important from a public health perspective for interventions to reduce further complications and the substantial costs associated with these. Since the aetiology is, in most cases, multfactorial, it is important to consider a multi-component approach to management, both pharmacological and non-pharmacological. Detection and treatment of triggering causes must have high priority in case of delirium. The aim of this review is to highlight the importance of delirium in the elderly population, given the increasing numbers of ageing people as well as increasing geriatric age.

Sociodemographic, behavioral and genetic determinants of allostatic load in a Swiss population-based study.

Allostatic load (AL) is a marker of physiological dysregulation which reflects exposure to chronic stress. High AL has been related to poorer health outcomes including mortality. We examine here the association of socioeconomic and lifestyle factors with AL. Additionally, we investigate the extent to which AL is genetically determined. We included 803 participants (52% women, mean age 48±16years) from a population and family-based Swiss study. We computed an AL index aggregating 14 markers from cardiovascular, metabolic, lipidic, oxidative, hypothalamus-pituitary-adrenal and inflammatory homeostatic axes. Education and occupational position were used as indicators of socioeconomic status. Marital status, stress, alcohol intake, smoking, dietary patterns and physical activity were considered as lifestyle factors. Heritability of AL was estimated by maximum likelihood. Women with a low occupational position had higher AL (low vs. high OR=3.99, 95%CI [1.22;13.05]), while the opposite was observed for men (middle vs. high OR=0.48, 95%CI [0.23;0.99]). Education tended to be inversely associated with AL in both sexes(low vs. high OR=3.54, 95%CI [1.69;7.4]/OR=1.59, 95%CI [0.88;2.90] in women/men). Heavy drinking men as well as women abstaining from alcohol had higher AL than moderate drinkers. Physical activity was protective against AL while high salt intake was related to increased AL risk. The heritability of AL was estimated to be 29.5% ±7.9%. Our results suggest that generalized physiological dysregulation, as measured by AL, is determined by both environmental and genetic factors. The genetic contribution to AL remains modest when compared to the environmental component, which explains approximately 70% of the phenotypic variance.

Latent Class Analysis of Gambling Activities in a Sample of Young Swiss Men : Association with Gambling Problems, Substance Use Outcomes, Personality Traits and Coping Strategies.

The study aimed to identify different patterns of gambling activities (PGAs) and to investigate how PGAs differed in gambling problems, substance use outcomes, personality traits and coping strategies. A representative sample of 4989 young Swiss males completed a questionnaire assessing seven distinct gambling activities, gambling problems, substance use outcomes, personality traits and coping strategies. PGAs were identified using latent class analysis (LCA). Differences between PGAs in gambling and substance use outcomes, personality traits and coping strategies were tested. LCA identified six different PGAs. With regard to gambling and substance use outcomes, the three most problematic PGAs were extensive gamblers, followed by private gamblers, and electronic lottery and casino gamblers, respectively. By contrast, the three least detrimental PGAs were rare or non-gamblers, lottery only gamblers and casino gamblers. With regard to personality traits, compared with rare or non-gamblers, private and casino gamblers reported higher levels of sensation seeking. Electronic lottery and casino gamblers, private gamblers and extensive gamblers had higher levels of aggression-hostility. Extensive and casino gamblers reported higher levels of sociability, whereas casino gamblers reported lower levels of anxiety-neuroticism. Extensive gamblers used more maladaptive and less adaptive coping strategies than other groups. Results suggest that gambling is not a homogeneous activity since different types of gamblers exist according to the PGA they are engaged in. Extensive gamblers, electronic and casino gamblers and private gamblers may have the most problematic PGAs. Personality traits and coping skills may predispose individuals to PGAs associated with more or less negative outcomes.

A feasability study of the analysis of the economic outcomes of specialized nutrition in obesity and weight management in Switzerland

The increasing prevalence of obesity and its associated complications requires specialized care to improve outcomes and control health care costs. Obesity is associated with numerous serious and costly medical problems requiring specialized care in managing health. The economic burden of obesity includes increased inpatient and outpatient medical expenditures as well as employer-related issues of absenteeism and associate costs. The objectives of this study are: - To describe the health consequences and the economic burden of obesity, - To review the existing treatment - To argue in favor of a specialized nutritional intervention that has shown to improve health and reduce obesity related health care costs. Therefore, expose the possibility of introducing the specialized nutrition in Switzerland and the feasibility of this project considering the medical trends and reimbursement system in Switzerland The benefits and outcomes for the patients will be the significant weight loss which reduces the severity and risk factors for complications and the improved health and quality of life. Weight loss will be a combination of a diet, exercise and behavioral interventions which are the basic recommendations for obesity treatment in addition to the specialized nutritional support. By nutritional support, we mean products that are intended to provide nutritional support in the dietary management of people with specific diseases and conditions when adequate intake of regular foods is compromised. These products are called, Food for special medical purposes FSMP. They are not intended to treat, cure, prevent, mitigate or have a direct impact on disease in a manner similar to drugs or other medical treatments and should be used under medical supervision. They also provide a low cost alternative to surgery. From a health care system perspective, the specialized nutrition will drive its advantage by reducing the utilization of medical services for obesity associated complications like medication, physician's consultations and surgical interventions arriving to a cost effective care for the hospitals, the health care organizations and the third party payers which are the health insurances.

The First International Workshop on Warning Criteria for Active Slides: technical issues, problems and solutions for managing early warning systems

Early warning systems (EWSs) rely on the capacity to forecast a dangerous event with a certain amount of advance by defining warning criteria on which the safety of the population will depend. Monitoring of landslides is facilitated by new technologies, decreasing prices and easier data processing. At the same time, predicting the onset of a rapid failure or the sudden transition from slow to rapid failure and subsequent collapse, and its consequences is challenging for scientists that must deal with uncertainties and have limited tools to do so. Furthermore, EWS and warning criteria are becoming more and more a subject of concern between technical experts, researchers, stakeholders and decision makers responsible for the activation, enforcement and approval of civil protection actions. EWSs imply also a sharing of responsibilities which is often averted by technical staff, managers of technical offices and governing institutions. We organized the First International Workshop on Warning Criteria for Active Slides (IWWCAS) to promote sharing and networking among members from specialized institutions and relevant experts of EWS. In this paper, we summarize the event to stimulate discussion and collaboration between organizations dealing with the complex task of managing hazard and risk related to active slides.

Under what conditions? Therapist and client characteristics moderate the role of change talk in brief motivational intervention.

OBJECTIVE: Client change talk has been proposed as a mechanism of change in motivational interviewing (MI) by mediating the link between therapist MI-consistent behaviors (MICO) and client behavioral outcomes. We tested under what circumstances this mechanism was supported in the context of a clinical trial of brief MI for heavy drinking among nontreatment seeking young men. METHOD: We conducted psycholinguistic coding of 174 sessions using the MI Skill Code 2.1 and derived the frequency of MICO and the strength of change talk (CTS) averaged over the session. CTS was examined as a mediator of the relationship between MICO and a drinking composite score measured at 3-month follow-up, controlling for the composite measure at baseline. Finally, we tested therapist gender and MI experience as well as client readiness to change and alcohol problem severity as moderators of this mediation model. RESULTS: CTS significantly predicted outcome (higher strength related to less drinking), but MICO did not predict CTS. However, CTS mediated the relationship between MICO and drinking outcomes when therapists had more experience in MI and when clients had more severe alcohol problems (i.e., significant conditional indirect effects). CONCLUSIONS: The mechanism hypothesized by MI theory was operative in our brief MI with heavy drinking young men, but only under particular conditions. Our results suggest that attention should be paid to therapist selection, training, and/or supervision until they reach a certain level of competence, and that MI might not be appropriate for nontreatment seeking clients drinking at a lower level of risk.

Disease profiles of detainees in the Canton of Vaud in Switzerland: gender and age differences in substance abuse, mental health and chronic health conditions.

BACKGROUND: Literature on the disease profile of prisoners that differentiates by age and gender remains sparse. This study aimed to describe the health of correctional inmates in terms of substance abuse problems and mental and somatic health conditions, and compare it by gender and age. METHODS: This study examined cross-sectional data from the Canton of Vaud in Switzerland on the health conditions of detainees who were in prison on January 1, 2011 or entered prison in 2011. Health conditions validated by physician examination were reported using the International Classification of Diseases (ICD) version 10. The analyses were descriptive by groups of prisoners: the entire sample (All), Men, Older adults and Women. RESULTS: A total of 1,664 individuals were included in the analysis. Men comprised 91.5 % of the sample and had a mean age of 33 years. The other 8.5 % were women and had an average age of 39. Older adults (i.e., age 50 and older) represented 7 % of the total sample. Overall, 80 % of inmates were non-Swiss citizens, but the proportion of Swiss prisoners was higher among the older adults (51 %) and women (29 %). Overall, 41 % of inmates self-reported substance abuse problems. Of those, 27 % were being treated by psychiatrists for behavioral disorders related to substance abuse. Chronic infectious diseases were found in 9 % of the prison population. In addition, 27 % of detainees suffered from serious mental health conditions. Gender and age had an influence on the disease profile of this sample: compared to the entire prison population, the older inmates were less likely to misuse illegal drugs and to suffer from communicable infections but exhibited more problems with alcohol and a higher burden of chronic health conditions. Female prisoners were more disposed to mental health problems (including drug abuse) and infectious diseases. In terms of chronic diseases, women suffered from the same conditions as men, but the diseases were more prevalent in women. CONCLUSION: It is important to understand the different disease profiles of prisoners by gender and age, as it helps identify the needs of different groups and tailor age-and gender-specific interventions.
