This crosssectional study involved 62 women who sought care at the Catholic University of Pelotas Psychological Clinical and were diagnosed with Major Depressive Disorder. The instruments were Mini International Neuropsychiatry Interview Plus, Bem Sex Role Inventory and Defense Style Questionnaire 40. The majority of the sample had a higher incidence of undifferentiated role (32.3 %). No significant difference was found between the defensive styles and the sex roles ( p> 0.05 ).There was a significant correlation, however, between the scores of masculinity and mature defense styles (r = 0.30, p 0.019) and between femininity and neurotic defense styles (r = 0.29, p 0.022). The findings suggest that depression may be related to poor self-concept and to femininity, while masculinity seems to be associated with greater mental health / O objetivo deste trabalho foi relacionar o papeis sexual com os estilos defensivos em mulheres com depressão. Este estudo transversal envolveu 62 mulheres que procuraram atendimento na Clínica Psicológica da Universidade Católica de Pelotas e foram diagnosticadas com Transtorno Depressivo Maior. Os instrumentos utilizados foram a Mini Internacional Neuropsychiatry Interview Plus, o Bem Sex Role Inventory e o Defense Style Questionnaire 40. A maioria da amostra apresentou maior incidência do papel indiferenciado (32,3%). Não foi encontrada diferença estatística significativa entre os papéis sexuais e os estilos defensivos (p>0,05). Houve correlação significativa, no entanto, entre os escores de masculinidade e os estilos defensivos maduros (r=0,30; p 0,019) e entre os de feminilidade e os estilos defensivos neuróticos (r=0,29; p 0,022). Os achados sugerem que a depressão pode estar relacionada a um fraco autoconceito e à feminilidade, enquanto a masculinidade parece estar associada a uma melhor saúde mental

METHOD: Women with postpartum depression were allocated to a brief psychotherapeutic intervention. To evaluate defense style and the alliance, the Defense Style Questionnaire and the Working Alliance Inventory were employed. The main outcome was the final score on the Edinburgh Postnatal Depression Scale (EPDS); anxiety and retention in treatment were also evaluated RESULTS: 59 patients were included; forty-six completed the therapy and 65.4% responded (EPDS<10). Intense use of immature defenses was related to the maintenance of depression and anxiety at endpoint, even when controlled for parity and social class. Results tended to confirm a hierarchy of defense styles. There were no significant correlations with the alliance measures at any sessions. CONCLUSIONS: Intense use of immature defenses was a factor of poor prognosis in psychotherapy, independently of the alliance, which strengthens their status as important variables for treatment selection / Avaliar o impacto dos estilos defensivos no desfecho da psicoterapia breve da depressão pós-parto e a relação dos mesmos com a aliança terapêutica. MÉTODO: Ensaio clínico randomizado, comparando a eficácia de duas intervenções breves para depressão pós-parto. Investigaram-se os mecanismos de defesa e aliança terapêutica mediante o Defense Style Questionnaire e o Working Alliance Inventory. O desfecho principal foi o escore na Edinburgh Postnatal Depression Scale (EPDS) ao final de 7 sessões. Também foram avaliados sintomas ansiosos e permanência em tratamento. RESULTADOS: Foram incluídas 59 pacientes; 46 completaram todas as sessões e 65,4% responderam ao tratamento (EPDS<10). Não houve correlação entre os estilos defensivos e os domínios da aliança em qualquer sessão. O uso intenso de defesas imaturas esteve relacionado à manutenção de sintomas depressivos e ansiosos ao final do tratamento, mesmo quando controlados para paridade e classe social. Os resultados tenderam a confirmar uma hierarquia que vai de um estilo imaturo a um estilo maduro. CONCLUSÕES: Uso intenso de defesas imaturas indicou mau prognóstico em psicoterapia breve, independentemente da aliança terapêutica, reforçando a possibilidade que sejam variáveis importantes para seleção sistemática para tratamento

Methodological study design was correlational crosssectional type. 65 patients took part in the study (Group 1: surgical candidates vs. Group 2: postoperative patients), mainly females (92,3%), who answered the Beck Depression Inventory (BDI), the Beck Anxiety Inventory (BAI), the Symptoms Assessment Scale (EAS- 40), and the version in Portuguese of The Toronto Alexithymia Scale (TAS-26) and of the Defensive Style Questionnaire (DSQ-40). Gr 1 showed mild anxiety and depression levels and Gr 2 minimum level (respectively, p< 0,001 e p< 0,01). The total average score for EAS- 40 and F2 and F3 (obesity-compulsion and somatization) were higher in Gr 1 when compared to Gr 2 (repetitively, p< 0,005, p< 0,005 e p< 0,001). On TAS, the total average score for F1 (ability to identify and describe feelings and distinguish them from bodily sensations) were higher in Gr 1 than in Gr 2 (respectively, p< 0,01 e p< 0,005). According to DSQ-40, there was a tendency for an immature defensive style in Gr 1 in comparison to Gr 2 (p< 0,02). In relation to the association between the variables and BMI, the correlations were negative for Gr 1 and F2 of TAS (daydreaming, p < 0,05) and for the mature factor of DSQ- 40 and Gr 2 (p < 0,05), which shows a trend towards a more mature and adaptive style in Gr 2. Correlations were positive and significant in relation to immature defenses - acting out (Gr 1: p<0,005 and Gr 2: p<0,05) and in the autistic fantasy in Gr 1 (p<0,05). The results show the psychological status of the participants, who are apt for bariatric surgery and point to a decrease in psychopathological symptoms proportional to weight loss after surgery. / Avalia depress?o, ansiedade, sintomas psicopatol?gicos, alexitimia e o estilo defensivo de pacientes obesos grau III, antes e depois de cirurgia bari?trica, e estima o grau de associa??o entre essas vari?veis.

Embora não seja reconhecido como um nutriente essencial, o silício (Si) reduz a severidade de oídios em diversas espécies vegetais quando acumulado na parte aérea. Contudo, apesar deste efeito benéfico ser amplamente relatado na literatura, ainda pouco se sabe dos mecanismos envolvidos. Este estudo avaliou o efeito das aplicações foliar e radicular de silicato de potássio, uma importante fonte de Si solúvel, na severidade de oídio e na indução de mecanismos de defesa pós-infecção em meloeiro. Os efeitos na doença foram avaliados em plantas inoculadas artificialmente ou naturalmente mantidas em casa de vegetação através da mensuração da dinâmica da epidemia e de seus componentes. Os resultados indicaram que tanto aplicações foliares como radiculares de silicato de potássio reduziram a área abaixo da curva de progresso da doença em 65% e 73%, respectivamente, comparadas ao tratamento controle sem aplicação. Tal redução foi resultado da alteração dos seguintes componentes epidemiológicos: eficiência de infecção, taxa de expansão da colônia, área da colônia, produção de conídios por área colonizada e taxa de progresso da epidemia. Contudo, a aplicação radicular foi mais eficiente que a foliar em atrasar o início da epidemia e em reduzir todos os componentes epidemiológicos, exceto a eficiência de infecção. A maior eficiência do silicato de potássio quando aplicado via raiz decorreu da maior concentração foliar do Si, a qual induziu uma antecipação (efeito priming) e um aumento da intensidade de expressão de mecanismos de defesa, fenômenos que não foram detectados no tratamento foliar. A aplicação radicular resultou na alteração de enzimas envolvidas na produção e catabolismo de espécies reativas de oxigênio, onde foi verificado aumento na atividade das enzimas superóxido dismutases e redução na atividade das enzimas catalases, principalmente nas primeiras 96 horas após a inoculação. O efeito priming também foi observado para as enzimas peroxidases, 1,3(4)-glucanases e quitinases e para o acúmulo de compostos fenólicos. Neste tratamento também ocorreu aumento na concentração de lignina em resposta à inoculação, contudo a concentração de malondialdeído foi reduzida, indicando que o Si aplicado nesta forma aliviou o estresse oxidativo sobre os lipídeos das membranas celulares da planta. Por outro lado, quando o silicato de potássio foi aplicado via foliar apenas a deposição de lignina aumentou comparado ao tratamento controle. Assim, depreende-se que os mecanismos de atuação do Si no controle da doença quando aplicado nesta forma, são distintos e envolvem, segundo a literatura, a formação de uma barreira físicoquímica sobre a cutícula resultado da polimerização do silicato de potássio. Tomados em conjunto, os resultados deste estudo evidenciaram que o Si tem papel ativo na modulação do sistema de defesa da planta, mas que sua efetividade depende de sua presença na forma solúvel no interior da planta, obtido por meio de sua absorção via raiz. Não obstante, os efeitos do silicato de potássio aqui relatados permitem concluir que a incorporação do produto a um sistema de manejo integrado, principalmente se fornecido via sistema radicular, terá efeitos positivos tanto na redução da epidemia de oídio como no meio ambiente, neste caso em função da redução no uso de fungicidas. / Silicon (Si) is not considered an essential nutrient of plants, but when it accumulates in the shoots it reduces powdery mildew severity on several species. However, despite this beneficial effect being widely reported in the literature, the mechanisms involved are still little understood. In this study, the effects of both foliar and root applications of potassium silicate, an important soluble source of Si, on the severity of powdery mildew and on the induction of postinfection defense mechanisms of melon were evaluated. Treatment effects were assessed by measuring the epidemics dynamic and its components in both artificially and naturally inoculated plants kept in the greenhouse. Results showed that the area under the disease progress curve was reduced by 65% and 73%, respectively by foliar and root application of potassium silicate, compared to control plants that were not supplied with potassium silicate. This effect accrued from the reduction of the infection efficiency, colony expansion rate, colony area, conidia production per colonized area and the epidemic progress rate. However, root application was more effective than foliar application on both delaying the onset of the epidemic and reducing most epidemic components, except for the infection efficiency. The greater efficiency of potassium silicate in controlling the disease when supplied via roots by irrigation correlated with higher foliar concentrations of Si which induced both a priming effect and increased expression of key defense responses. These phenomena, however, were not observed when potassium silicate was sprayed on leaves. Root supply of Si altered the activity of enzymes involved in the production and catabolism of reactive oxygen species, resulting in the increased activity of superoxide dismutase and reduced activity of catalases mainly in the first 96 hours after inoculation. Root application also primed the activity of peroxidases, 1,3(4)-glucanases, chitinases and the accumulation of phenolic compounds. Lignin concentration also increased in response to inoculation while the concentration of malondialdeide reduced indicating that Si decreased the oxidation of lipids of the plant cell membranes. In contrast, when Si was sprayed on the leaves, only an increase in lignin deposition was observed compared to the control treatment. Thus, it appears that the mechanisms of powdery mildew control in this case are distinct and, according to literature data, could include the formation of a physical-chemical barrier on the cuticle as the result of potassium silicate polymerization. Taken together, the results showed that Si plays an active role in modulating the host defense system, but only when present in the soluble form inside the plant which can be achieved by root uptake. Nevertheless, the effects of potassium silicate reported here allowed concluding that the inclusion of this compound in an integrated management system, mainly if supplied via roots, will render positive effects both on reducing the disease in melon plants and on the environment, in this case through reducing the use of fungicides.

Red alder (Alnus rubra) is a tree species with high economic and ecological importance. It is subject to defoliation during unpredictable, episodic outbreaks of tent caterpillars (Malacosoma spp.) that result in reduced growth, decreased wood production, unsightly appearance and mortality in severe cases. Alder trees are weakened by severe and repeated tent caterpillar defoliation, and this can increase the susceptibility of the trees to other pests, diseases and drought. Repeated attack by tent caterpillars can cause decline in red alder populations, which can have potential negative impacts on the ecological and economic benefits of the species. Evidence from other species has shown that plants produce phytochemicals for defense against herbivores at a cost to growth and reproduction, but the relative magnitude of the cost of allocating available resources to defense depends on the level of the resources, and the plant genotype. The quality of a plant as food for herbivores is influenced by leaf physical and biochemical traits, and these traits change during a growing season or upon attack by herbivores. My research aimed to explore the defense mechanisms of red alder against western tent caterpillars (Malacosoma californicum) and determine the resistance variation among and within red alder populations, and to evaluate red alder available resource (nitrogen) allocation to defense and growth. Bioassay feeding trials were conducted in 2014 and 2015 with western tent caterpillars (WTC) (M. californicum) on twenty red alder clones from ten provenances. Phenology and quality of red alder leaves as food for the defoliators were analyzed to determine if budburst, leaf chemical content, water content or physical traits are major determinants of western tent caterpillars preference for red alder leaves. In another experiment, one-year-old seedlings from 100 half-sib red alder families were treated with two levels of ammonium nitrate (NH4NO3) in two growing seasons in a common garden. Growth, herbivore defense-related traits and root nodulation were measured and ranked among the plant genotypes and between the two nitrogen (N) treatments. Leaves from the two N treatments and different alder families were also used for bioassay feeding trials with WTC larvae to determine effects of N and genotype on red alder herbivory resistance. In my final experiments, I harvested and analyzed leaves from three-year-old red alder trees from five different families on eight dates from early April to mid-October 2016 to quantify oregonin and total phenolics concentrations, and wound induction experiments were conducted to determine if the concentrations of the chemicals vary during a growing season and upon attack by insects. Alder clones and families differed in percentage leaf area eaten by caterpillars and in leaf defense traits. The concentrations of foliar phenolic compounds negatively correlated with the percentage leaf area eaten by the caterpillars, but the results suggest a threshold, above which the concentration of each of the chemicals appeared to reduce WTC feeding, individually. Particularly, foliar oregonin concentration above 20 % leaf dry weight consistently appeared to reduce feeding by caterpillars. N availability had significant effects on red alder seedling total dry biomass and leaf N concentration. There was a clear trade-off between red alder seedling growth, and content of the phenolic compounds and leaf thickness, which supports the growth-differentiation balanced hypothesis in relation to resource availability. The concentration of oregonin varied during the growing season and there were no significant responses of any of the measured compounds to wounding. The results suggest that red alder foliar oregonin, condensed tannin and total phenolics are constitutive defenses and are not wound-induced. The effects of leaf total phenolic and condensed tannin concentrations on insect herbivory have been documented by past studies but the effects of oregonin concentration in red alder leaves on tent caterpillar feeding is a novel finding. / Graduate / 2020-04-18

Este trabalho, fundamentando-se no referencial psicanalítico, estuda o fenômeno HIV/aids a partir do discurso de quatro pessoas vivendo com aids, entrevistados individualmente ao longo de três anos. O referencial psicanalítico funcionou como ferramenta teórico-metodológica para a condução das entrevistas, assim como para a leitura do material produzido nos encontros com os sujeitos da pesquisa. Foram fundamentais as concepções da Teoria dos Campos e de clínica extensa do psicanalista brasileiro Fabio Herrmann, as quais possibilitam o emprego do método psicanalítico num território fora do setting clássico, incluindo a pesquisa acadêmica. Este trabalho partiu do pressuposto de que as patologias, sobretudo as crônicas e incuráveis, provocam uma ferida narcísica em suas vítimas. No caso da aids, isso seria exacerbado pela vulnerabilidade que a doença provoca, pelos efeitos adversos dos remédios e pelos estigmas sociais que lhe estão associados. O objetivo da pesquisa foi verificar quais são as estratégias psíquicas que os doentes utilizam para enfrentar essa situação e para tentar reparar essa ferida. Constatou-se que essas pessoas se sentem arremessadas dentro de um campo do “angustiante" [das Ängstlichen] quando se percebem submersos por essa moléstia. A reação do eu para lidar com esse angustiante lhe provocaria uma cisão (Ichspaultung), fazendo com que a realidade aterrorizadora possa coexistir psiquicamente com o desejo de reparar a ferida narcísica e com um luto indelével por si mesmo. Dessa forma, a aids é incorporada à dinâmica psíquica do doente nos termos daquilo que Freud denominou de das Unheimliche. O eu, graças a seu poder de síntese, mesmo combalido por uma força externa impiedosa, pode ser capaz de confrontá-la e se manter integrado, apesar das perdas irreparáveis. / This production, based on the psychoanalytical work, studies the HIV/AIDS phenomenon, from the speech of four AIDS patients, who have been interviewed for three years. The psychoanalytical reference functioned as a methodological and theoretical tool in order to run the interviews, as well as for the reading of the material produced along the meetings with the subjects of the research. The conceptions of the Multiple Fields Theory and the extense clinic by the Brazilian Psychoanalyst Fabio Herrmann have been of great importance, which support the usage of the psychoanalytical method, outside the classical setting, including academic research. This piece of work gets from the assumption of which the pathologies, mainly the chronicle and incurable ones, induce a narcissistic injury over their victims. When it comes to AIDS, this situation would become aggravated by the vulnerability that the disease provokes, by the adverse effects of the medicines and by the social stigmas which are linked to them. The aim of the research was verifying what psychic strategies the patients use in order to face such situation and to try to fix this wound. It was proved that the AIDS patients feel themselves thrown into a field of “angst" [das Ängstlichen] when they realize they are submerged by this disease. The ego reaction to deal the distressing field would provoke an ego splitting (Spaultung), occurring that the frightening reality is able to psychically coexist with the desire of repairing the narcissistic wound and with the indelible mourning by itself. In that case, AIDS is shared in the psychic dynamic of the patient in terms of what that Freud named as das Unheimliche. The ego, thanks to its synthesis power, even though it is grown weak by an outside and merciless force, may be able to face it and keep integrated, although the irreparable losses.

The main purpose of the present studies has been to develop the Defense Mechanism Test (DM1) for clinical assessment of severe psychopathology with the focus on the concept of Borderline Personality Organization (BPO) according to Kemberg. By relating the DMT and the Structural Interview to each other, the concurrent validity of the concept of Personality Organization (PO) for psychiatric inpatients has been investigated. Two different assessment approaches have been used for this purpose. One has been to take a theoretical perspective as the starting-point for the classification of PO by means of the DMT. The other has been a purely empirical approach designed to discern natural and discriminating patterns of DMT distortions for different diagnostic groups. A dialogue is also in progress between DMT and current research on the Rorschach test in order to increase understanding of borderline phenomena and pathology. The overall results support Kemberg's idea that borderline patients are characterized by specific intrapsychic constellations different from those of both psychotic and neurotic patients. Both the DMT and the Structural Interview provide reliable and consistent judgements of PO. Patients with the syndrome diagnosis Borderline Personality Disorder exhibit different perceptual distortions from patients suffering from other personality disorders. The classic borderline theory is a one-dimensional developmental model, where BPO constitutes a stable intermediate form between neurosis and psychosis. The present results suggest that a two-dimensional model might be more powerful. Hence, the level of self- and object representations and reality orientation might be considered both from a developmental gad an affective perspective across varying forms of pathology. Kemberg suggests that borderline and psychotic patients share a common defensive constellation, centered around splitting, organizing self- and object representations. This view did not find support. The defensive pattem of the BPO patients is significantly different from the PPO defensive pattern. The BPO patients form their self- and object images affectively and thus the self- and object representations would seem to influence the defensive organization and not the other way around. The results have implications for the procedure and the interpretation of the DMT e.g. one and the same DMT picture can discern different kinds of personality; reactions other than the operationalized defense categories in the DMT manual can be valid predictors of PO; some of the DMT defenses described in the manual have to be reconceptualized such as isolation, repression and to some degree denial. Multivariate models are powerful tools for the integration of reactions to DMT into diagnostic patterns. / <p>Diss.

In my thesis, I focused on the ethical and cultural dimension of social work, application of ethical principles and choice of attitude by a helping professional when working with a client. Subsequently, I followed changes in application of these ethical principles and changes of attitude in high-strain situations in the contact with a so-called difficult client. Further, I focused on the defence mechanisms which a helping professional chooses to cope with high-strain situations and manage his job well. In the individual chapters of the theoretical parte, by the analysis of scientific literature I described theoretical bases of the professional relationship between a social/health social worker and a klient and I focused on the realization of this relationship and on what it brings the worker in high-strain situations when working with the so-called difficult client. In the empirical part, I set one main goal to find out how social workers react on the ethical level in high-strain situations while interacting with difficult clients. Partial goals were designed to find out what ethical principles social workers apply, what attitudes they choose, which clients they consider difficult and what defence mechanisms they develop to cope with high-strain situations. To reflect these goals, I set one main research question and four partial ones. For the collection of data, I opted for the method of quantitative research and I used the questioning method in the form of a half-structured interview. I chose the set of respondents for my research by the method of simple random sampling. To process the research data, I chose the method of case study. Processing the interviews and analysing them, I found out that social workers in high-strain situations do not change their application of ethical principles. Further, I found out that the choice of attitude in high-strain situations changes and that social workers choose, instead of a partner attitude based on equality, a more or less directive stance. All of the respondents met a difficult client at work and dealing with high-strain situations causes them certain indisposition they have to cope with. The answer to the main research question is thus that on ethical level social workers react in high-strain situation by a shift in the choice of their attitude and solving ethical dilemmas. It was a hostile client that the social workers listed most frequently in the typology of clients. It became evident during the interviews what kind of defence mechanisms social workers choose to be able to cope with high-strain situations. The thesis may provide information to the general public and experts.

Les recherches en psychologie clinique interculturelle décrivent avec pertinence les aménagements psychiques et/ou psychopathologiques engagés par les processus acculturatifs. Cependant, se pose la question de la façon dont les différentes cultures au carrefour desquelles se situe un sujet vont interagir entre elles au sein même de l'individu. Ainsi, la rencontre des cultures ne se produit pas uniquement dans le champ social, mais aussi dans l'espace psychique, de sorte que l'interculturel ne décrit pas simplement un phénomène extérieur, mais plus singulièrement une composition subjective. Pouvons-nous produire une représentation topique de cette pluralité interne ? Que nous apporterait-elle dans la compréhension du sujet interculturel ? Afin de répondre à ces questions, nous proposons une approche interdisciplinaire et transversale entre ces deux « commutateurs » du social en l'individu que sont le Surmoi et l'habitus. La modélisation d'un « acteur pluriel » (Lahire, 2001), à l'image des matrices de socialisation et espaces sociaux auxquels il participe, servira de socle à partir duquel nous penserons la pluralité interne du sujet interculturel. Les dispositifs de régulation psychique (mécanismes de défense et stratégies de coping) seront nos indicateurs. Notre étude porte sur la comparaison de sujets (N=497) autochtones et issus d'une immigration, en fonction de l'aire géographique et culturelle d'origine et du degré d'ascendance immigrée. Nos résultats concordent globalement avec l'hypothèse d'un sujet interculturel sur le modèle d'un acteur pluriel. Cette perspective nous permet de proposer une représentation topique de l'incidence de l'interculturalité comme pluralité interne, mais aussi, à un niveau empirique de dégager une représentation dynamique des incidences de l'immigration sur les sujets qui en sont issus. / Research in intercultural clinical psychology describes the psychic and/or the psychopathological changes incurred by the acculturation process. However, the question arises of how different cultures will interact with each other within the psychological space of the individual. Thus, the meeting of cultures does not only occur within the social field, but also within the psychicological space. The intercultural aspects do not simply refer to an outside reality, but more particularly to a subjective experience. Can we produce a representation of this internal plurality? What would be its contribution in understanding the intercultural domain? To answer these questions, we propose a transversal and interdisciplinary approach that strives to understand how the two social "switches" of the individual operates, that is the superego and the habitus. The modeling of a "plural actor" (Lahire, 2001), in the image of socialization matrices and social spaces to which he belongs, will serve a basis from which the internal plurality of cultures will be addressed. The regulatory mechanisms of the psychic (the defense mechanisms and the coping strategies) will be our indicators. Our study focuses on the comparison between non-immigrant and immigrant individuals (N=497), in function of their geographical and cultural origin, and the degree of immigrant descent. Our results are consistent with the hypothesis according to which an intercultural topic should be integrated in the model of a plural actor. This perspective allows us to provide a clear picture of the impact of multiculturalism as internal plurality, but also to generate a dynamic representation of the effects of immigration on related topics.
