Assitência de enfermagem a pacientes com desordem bipolar e sentimentos da estudante de enfermagem: estudo de caso

Este trabalho é relato de uma experiência, enquanto aluna de graduação, durante a Disciplina de Enfermagem Psiquiátrica, onde acompanhei uma paciente portadora de Psicose Maníaco Depressiva (PMD) de ciclagem rápida. A interação enfermeira-paciente é muito importante pois é através de um bom relacionamento que firmamos um vínculo de confiança, capaz de ajudar o paciente nas duas fases distintas, com planos de cuidados individualizados. Comento os comportamentos depressivos e maníacos da paciente e as técnicas terapêuticas utilizadas em cada fase. Meus sentimentos durante a interação foram analisados frente aos comportamentos apresentados pela paciente.

Transtorno afetivo bipolar e a ambivalência em relação à terapia medicamentosa: analisando as condições causais

Este estudo buscou compreender as condições causais da ambivalência da pessoa com transtorno afetivo bipolar (TAB) em relação ao seguimento da terapêutica medicamentosa. Foi utilizada a abordagem qualitativa, tendo como referencial metodológico a Teoria Fundamentada nos Dados, à luz do Interacionismo Simbólico. Participaram do estudo 14 pessoas com TAB que estavam em acompanhamento em um Ambulatório de Transtornos do Humor de um hospital universitário e 14 familiares indicados pelas mesmas. A entrevista e observação foram as principais formas de obtenção de dados. Os resultados revelaram três categorias que descrevem as referidas condições causais: vivendo as crises do transtorno; tendo necessidade do medicamento e convivendo com os efeitos colaterais dos medicamentos. Este estudo aponta para necessidade de mudança de atitude dos profissionais de saúde de culpabilizar o paciente pela interrupção do tratamento para aquela de escuta, de valorização do seu universo simbólico e afetivo bem como de parceria no tratamento.

Grupo de psicoeducação no transtorno afetivo bipolar: reflexão sobre o modo asilar e o modo psicossocial

O Transtorno Afetivo Bipolar (TAB), conhecido por sua cronicidade, complexidade e altos índices de morbidade e mortalidade, é uma das principais causas de incapacitação no mundo. Há evidências crescentes de que seu curso pode ser modificado por abordagens psicoterápicas como a psicoeducação, que promove o aumento do funcionamento social e ocupacional, bem como da capacidade de manejarem situações estressantes. Trata-se de um relato de experiência sobre um grupo de psicoeducação para familiares e portadores de TAB, sendo esse pautado pela reflexão dos componentes do paradigma das práticas em saúde mental. A reflexão sobre os modos asilar e psicossocial quanto às concepções de objeto e modo de trabalho, possibilitou situar o grupo no modo psicossocial, pois o conhecimento e a vivência experimentados favorecem a autonomia dos sujeitos, que têm maiores chances de se posicionarem frente às dificuldades que lhes sobrevêm na sua existência-sofrimento.

Implicações de um grupo de Psicoeducação no cotidiano de portadores de Transtorno Afetivo Bipolar

Há evidências crescentes de que o curso Transtorno Afetivo Bipolar (TAB) pode ser modificado por abordagens psicoterápicas, tais como a Psicoeducação. Assim, o objetivo deste trabalho foi identificar as implicações do grupo de Psicoeducação no cotidiano dos portadores. Para tanto, optou-se pelo estudo qualitativo, do tipo Estudo de Caso. Foram incluídos doze portadores de TAB que tiveram pelo menos seis participações no Grupo de Psicoeducação desenvolvido na Faculdade de Medicina de São José do Rio Preto (FAMERP). Foram realizadas entrevistas semi-estruturadas, gravadas, transcritas e trabalhadas por meio da Análise Temática. Este estudo demonstrou que tal experiência grupal favoreceu a aquisição de conhecimento; a conscientização da doença e adesão ao tratamento; a realização de mudanças positivas na vida; a possibilidade de ajudar outros portadores a se beneficiarem do aprendizado construído no grupo; a descoberta de outras realidades e estratégias de enfrentamento, obtidas por meio da troca de experiências entre os participantes.

Transtorno afetivo bipolar: perfil farmacoterapêutico e adesão ao medicamento

Este estudo teve como objetivos verificar a adesão de portadores de transtorno afetivo bipolar (TAB) à terapêutica medicamentosa e identificar possíveis causas de adesão e não adesão ao medicamento de acordo com o perfil farmacoterapêutico. Trata-se de estudo transversal, descritivo, realizado em Núcleo de Saúde Mental de um município do interior paulista. Participaram do estudo 101 pacientes com TAB. Para coleta dos dados, utilizou-se a entrevista estruturada e o teste de Morisky-Green e, para a análise dos mesmos, o programa Statistical Package for the Social Science. Os resultados mostraram que a maioria (63%) dos sujeitos investigados não adere ao medicamento. Apesar de não ter ocorrido diferenças significativas entre o grupo de aderentes e não aderentes, para as variáveis investigadas, foi possível verificar a utilização de polifarmacoterapia e regimes terapêuticos complexos no tratamento do TAB. Permanece como desafio a implementação de estratégias que possam melhorar, na prática, a adesão de pacientes ao tratamento medicamentoso.

Model endophenotype for bipolar disorder: Qualitative Analysis, etiological factors, and research areas

The aim of this study is to present an updated view of the writings on the endophenotype model for bipolar disorder using analytical methodologies. A review and analysis of networks was performed through descriptors and keywords that characterize the composition of the endophenotype model as a model of health. Information was collected from between 1992 and 2014, and the main thematic areas covered in the articles were identified. We discuss the results and question their cohesion, emphasizing the need to strengthen and identify the points of connection between etiological factors and characteristics that make up the model of endophenotypes for bipolar disorder.

Losses of immunoreactive parvalbumin amacrine and immunoreactive alphaprotein kinase C bipolar cells caused by methylmercury chloride intoxication in the retina of the tropical fish Hoplias malabaricus

To quantify the effects of methylmercury (MeHg) on amacrine and on ON-bipolar cells in the retina, experiments were performed in MeHg-exposed groups of adult trahiras (Hoplias malabaricus) at two dose levels (2 and 6 µg/g, ip). The retinas of test and control groups were processed by mouse anti-parvalbumin and rabbit anti-alphaprotein kinase C (alphaPKC) immunocytochemistry. Morphology and soma location in the inner nuclear layer were used to identify immunoreactive parvalbumin (PV-IR) and alphaPKC (alphaPKC-IR) in wholemount preparations. Cell density, topography and isodensity maps were estimated using confocal images. PV-IR was detected in amacrine cells in the inner nuclear layer and in displaced amacrine cells from the ganglion cell layer, and alphaPKC-IR was detected in ON-bipolar cells. The MeHg-treated group (6 µg/g) showed significant reduction of the ON-bipolar alphaPKC-IR cell density (mean density = 1306 ± 393 cells/mm²) compared to control (1886 ± 892 cells/mm²; P < 0.001). The mean densities found for amacrine PV-IR cells in MeHg-treated retinas were 1040 ± 56 cells/mm² (2 µg/g) and 845 ± 82 cells/mm² (6 µg/g), also lower than control (1312 ± 31 cells/mm²; P < 0.05), differently from the data observed in displaced PV-IR amacrine cells. These results show that MeHg changed the PV-IR amacrine cell density in a dose-dependent way, and reduced the density of alphaKC-IR bipolar cells at the dose of 6 µg/g. Further studies are needed to identify the physiological impact of these findings on visual function.

Erythrocyte phosphoglucomutase activity of bipolar I patients currently using lithium or carbamazepine

Lithium has been used for the last five decades to treat bipolar disorder, but the molecular basis of its therapeutic effect is unknown. Phosphoglucomutase is a key enzyme in the metabolism of glycogen. In yeast, rabbit and human HEK293 cells, it is inhibited by lithium in the therapeutic concentration range. We measured the phosphoglucomutase activity in erythrocytes and the inhibitor constant for lithium in a population of healthy subjects and compared them to those of bipolar patients treated with lithium or carbamazepine. The specific activity of phosphoglucomutase measured in vitro in erythrocytes from control subjects presented a normal distribution, with the difference between the lowest and the highest activity being approximately 2-fold (0.53-1.10 nmol mg Hb-1 min-1). Comparison of phosphoglucomutase activity in untreated bipolar patients and control subjects showed no significant difference, whereas comparison between bipolar patients treated with carbamazepine or lithium revealed significantly lower mean values in patients treated with carbamazepine (747.3 ± 27.6 vs 879.5 ± 35.9 pmol mg Hb-1 min-1, respectively). When we studied the concentration of lithium needed to inhibit phosphoglucomutase activity by 50%, a bimodal distribution among the population tested was obtained. The concentration of LiCl needed to inhibit phosphoglucomutase activity by 50% was 0.35 to 1.8 mM in one group of subjects and in the other it was 3 to 4 mM. These results suggest that phosphoglucomutase activity may be significant in patients with bipolar disorder treated with lithium and carbamazepine.

Memory mood congruency phenomenon in bipolar I disorder and major depression disorder patients

The objective of the present study was to evaluate memory performance in tasks with and without affective content (to confirm the mood congruency phenomenon) in acutely admitted patients with bipolar I disorder (BD) and major depression disorder (MDD) and in healthy participants. Seventy-eight participants (24 BD, 29 MDD, and 25 healthy controls) were evaluated. Three word lists were used as the memory task with affective content (positive, negative and indifferent). Psychiatric symptoms were also evaluated with rating scales (Young Mania Rating Scale for mania and Hamilton Depression Rating Scale for depression). Patients were selected during the first week of hospitalization. BD patients showed higher scores in the word span with positive tone than MDD patients and healthy controls (P = 0.002). No other difference was observed for tests with affective tone. MDD patients presented significantly lower scores in the Mini-Mental State Exam, logical memory test, visual recognition span, and digit span, while BD patients presented lower scores in the visual recognition test and digit span. Mood congruency effect was found for word span with positive tone among BD patients but no similar effect was observed among MDD patients for negative items. MDD patients presented more memory impairment than BD patients, but BD patients also showed memory impairment

Group cognitive behavior therapy for bipolar disorder can improve the quality of life

Bipolar disorder (BD) can have an impact on psychosocial functioning and quality of life (QoL). Several studies have shown that structured psychotherapy in conjunction with pharmacotherapy may modify the course of some disorders; however, few studies have investigated the results of group cognitive behavior therapy (G-CBT) for BD. Our objective was to evaluate the effectiveness of 14 sessions of G-CBT for BD patients, comparing this intervention plus pharmacotherapy to treatment as usual (TAU; only pharmacotherapy). Forty-one patients with BD I and II participated in this study and were randomly allocated to each group (G-CBT: N = 27; TAU: N = 14). Thirty-seven participants completed the treatment (women: N = 66.67%; mean age = 41.5 years). QoL and mood symptoms were assessed in all participants. Scores changed significantly by the end of treatment in favor of the G-CBT group. The G-CBT group presented significantly better QoL in seven of the eight sub-items assessed with the Medical Outcomes Survey SF-36 scale. At the end of treatment, the G-CBT group exhibited lower scores for mania (not statistically significant) and depression (statistically significant) as well as a reduction in the frequency and duration of mood episodes (P < 0.01). The group variable was significant for the reduction of depression scores over time. This clinical change may explain the improvement in six of the eight subscales of QoL (P < 0.05). The G-CBT group showed better QoL in absolute values in all aspects and significant improvements in nearly all subscales. These results were not observed in the TAU control group.

Specific alterations in plasma proteins during depressed, manic, and euthymic states of bipolar disorder

Bipolar disorder (BD) is a common psychiatric mood disorder affecting more than 1-2% of the general population of different European countries. Unfortunately, there is no objective laboratory-based test to aid BD diagnosis or monitor its progression, and little is known about the molecular basis of BD. Here, we performed a comparative proteomic study to identify differentially expressed plasma proteins in various BD mood states (depressed BD, manic BD, and euthymic BD) relative to healthy controls. A total of 10 euthymic BD, 20 depressed BD, 15 manic BD, and 20 demographically matched healthy control subjects were recruited. Seven high-abundance proteins were immunodepleted in plasma samples from the 4 experimental groups, which were then subjected to proteome-wide expression profiling by two-dimensional electrophoresis and matrix-assisted laser desorption/ionization-time-of-flight/time-of-flight tandem mass spectrometry. Proteomic results were validated by immunoblotting and bioinformatically analyzed using MetaCore. From a total of 32 proteins identified with 1.5-fold changes in expression compared with healthy controls, 16 proteins were perturbed in BD independent of mood state, while 16 proteins were specifically associated with particular BD mood states. Two mood-independent differential proteins, apolipoprotein (Apo) A1 and Apo L1, suggest that BD pathophysiology may be associated with early perturbations in lipid metabolism. Moreover, down-regulation of one mood-dependent protein, carbonic anhydrase 1 (CA-1), suggests it may be involved in the pathophysiology of depressive episodes in BD. Thus, BD pathophysiology may be associated with early perturbations in lipid metabolism that are independent of mood state, while CA-1 may be involved in the pathophysiology of depressive episodes.

RC-IAL cell line: sensitivity of rubella virus grow

OBJECTIVE: The rapid growth of the rubella virus in RC-IAL² with development of cytopathic effect, in response to rubella virus infection, is described. For purposes of comparison, the rubella virus RA-27/3 strain was titered simultaneously in the RC-IAL, Vero, SIRC and RK13 cell lines. METHODS: Rubella virus RA-27/3 strain are inoculated in the RC-IAL cell line (rabbit Kidney, Institute Adolfo Lutz). Plates containing 1.5x10(5) cells/ml of RC-IAL line were inoculated with 0.1ml s RA-27/3 strain virus containing 1x 10(4)TCID50/0.1ml. A 25% cytopathic effect was observed after 48 hours and 100% after 96 hours. The results obtained were compared to those observed with the SIRC, Vero and RK13 cell lines. Rubella virus was detected by immunohistochemistry. RESULTS: With the results, it was possible to conclude that the RC-IAL cell line is a very good substrate for culturing rubella virus. The cells inoculated with rubella virus were examined by phase contrast microscopy and showed the characteristic rounded, bipolar and multipolar cells. The CPE in RC-IAL was observed in the first 48 hours and the curve of the increased infectivity was practically the same as observed in other cell lines. CONCLUSIONS: These findings are important since this is one the few cell lines described in the literature with a cytopathic effect. So it can be used for antigen preparation and serological testing for the diagnosis of specific rubella antibodies.

Atención de pacientes pobres con trastornos afectivos de la ciudad de México

OBJETIVO: Describir los caminos de atención seguidos por población adulta, que cubre los criterios diagnósticos de trastornos depresivos, distimia y trastorno bipolar. MÉTODOS: La información se obtuvo mediante una entrevista personal, utilizando un cuestionario estandarizado que incluía secciones del Composite International Diagnostic Interview sobre trastornos afectivos y una sección sobre utilización de servicios. Los entrevistados (n=1,486) fueron seleccionados a partir de una muestra aleatoria, estratificada según las variables socioeconómicas y multietápicas (manzanas, viviendas, individuos), residentes en la Ciudad de México. RESULTADOS: Un número importante de las personas con trastornos afectivos informaron recurrir tanto a servicios formales como informales de atención. Se observó que en muchos casos se estableció el primer contacto con un médico general (81% de los hombres con trastornos depresivos, 100% con distimia y 36% con trastornos bipolares; 44.4% de las mujeres con depresión, 23% con distimia y 100% con trastornos bipolares). Del mismo modo, se observó que el 45% de los hombres con depresión, el 40% de los varones con distimia y el 65% de las mujeres con trastorno bipolar concluyeron los caminos asistenciales con el uso de los recursos proporcionados por las medicinas alternativas. CONCLUSIONES: El uso entremezclado de diversos sistemas de atención cumple por lo menos dos funciones. 1) permite armar un conjunto de opciones potenciales y así maximizar los recursos curativos con los que se cuenta, 2) permite atender distintos aspectos de una misma enfermedad donde un sólo sistema médico no puede satisfacer la complejidad del evento.

The use of a modular titanium endoprosthesis in skeletal reconstructions after bone tumor resections: method presentation and analysis of 37 cases

We analyzed 37 patients who underwent segmental wide resection of bone tumors and reconstruction with a modular titanium endoprosthesis at the Orthopaedic Oncology Group, between 1992 and 1998. Twelve patients were male and 25 were female, with a mean age of 30 years (9 - 81). The mean follow-up was 14 months (2 - 48). The diagnoses were: osteosarcoma (14 cases), metastatic carcinoma (10), Ewing's sarcoma (4), giant cell tumor (4), malignant fibrous histiocytoma (3), chondrosarcoma (1), and aneurysmal bone cyst (1). Eleven articulated total knee, 8 partial proximal femur with bipolar acetabulum, 8 partial proximal humerus, 3 total femur, 2 partial proximal tibia, 2 diaphyseal femur, 2 diaphyseal humerus, and 1 total proximal femur with cementless acetabulum endoprosthesis implant procedures were done. The complications related to the procedure included: infection (5 cases), dislocation (3), module loosening (1), and ulnar nerve paresthesia (1). We used the following criteria for the clinical evaluation: presence of pain, range of motion, reconstruction stability, surgical and oncologic complications, and patient acceptance. The results were good in 56.8% of the cases, regular in 32.4% and poor in 10.8%.
