Orientadores: Maria Jose Duarte Osis, Anibal Faundes / Dissertação (mestrado) - Universidade Estadual de Campinas, Faculdade de Ciencias Medicas / Made available in DSpace on 2018-11-09T13:21:04Z (GMT). No. of bitstreams: 1 Padua_KarlaSimoniade_M.pdf: 1407442 bytes, checksum: beb48def0505292c983d370ac238299a (MD5) Previous issue date: 2008 / Resumo: Para melhor compreender a alta incidência de cesarianas realizadas no mundo entre 2004 e 2005, a Organização Mundial da Saúde desenvolveu um estudo multicêntrico em 54 países, inclusive o Brasil: Esse estudo teve como objetivo principal criar um sistema global para monitorar os resultados de saúde materna e perinatal, verificando a sua associação com a forma de término do parto. Objetivo: Avaliar a prevalência de cesariana segundo características do hospital e características sociodemográficas e reprodutivas das mulheres nos estados de São Paulo, Pernambuco e no Distrito Federal. Material e Método: Estudo de corte transversal com dados do Sistema Global de Dados para a Saúde Materna e Perinatal, da Organização Mundial da Saúde. Analisaram-se dados de 15.379 mulheres que tiveram parto entre setembro de 2004 e março de 2005, realizando análises bivariada e por regressão logística múltipla. Resultados: A prevalência de cesarianas foi maior nos hospitais com índice de complexidade alta, com financiamento do atendimento pelo SUS e particular, em que havia só estudantes de medicina, e naqueles em que não havia parteiras envolvidas na atenção ao parto; entre mulheres com idade > 30 anos, com mais de oito anos de escolaridade, casadas/unidas, e com índice de massa corpórea > 30. Diversas condições apresentadas durante a gravidez ou parto, diagnóstico de HIV da parturiente, maior peso e perímetro cefálico do recém-nascido, e maior número de consultas de pré-natal se associaram a maior prevalência de cesariana. Na análise múltipla mostraram associação direta: presença de hipertensão/eclâmpsia, doenças crônicas, maior perímetro cefálico do recém-nascido, não ter nenhum nascimento anterior e ter tido cesárea na última gravidez. Conclusões: Condições patológicas da gravidez, características do recém-nascido e características reprodutivas da parturiente associaram-se independentemente à realização de cesariana, o que não se verificou com características dos hospitais e características sociodemográficas das parturientes. Isto, provavelmente, foi devido à homogeneidade da amostra estudada, tanto de hospitais quanto de mulheres / Abstract: In order to better understand the high incidence of C-sections in the world, the World Health Organization (WHO) carried out a multicentric study in 54 countries, including Brazil. Data were collected between 2004 and 2005. The study main objective was to create a global system for monitoring maternal and perinatal results and their association with mode of delivery. Objective: To evaluate the prevalence of cesarean-section in Brazil according to hospital and women¿s characteristics in the states of São Paulo, Pernambuco and the Federal District. Material and Methods: A cross-sectional study using the Brazilian data from the 2005 WHO Global Survey on Maternal and Perinatal Health database. Data from 15,379 women who had a delivery between September 2004 and March 2005 in the selected hospitals were analyzed. The associations between categorical variables were tested by chi-square test and factors associated with caesarean section were identified by stepwise logistic regression. Results: The C-section prevalence was higher in the hospitals with higher complexity index, payment by SUS and private, where there were only medical students, midwives were not involved in delivery care, among women > 30 years old, with more than eight years of schooling, married/in union, and with body mass index > 30. Several conditions presented during pregnancy or childbirth, the mother¿ HIV diagnosis, the greater weight and newborn head circumference, and the highest number of pre-natal visits were also associated to higher prevalence of cesarean-section. In the multiple regression analyses the following variables were directly associated to C-section: presence of hypertension/eclampsia, chronic diseases, greater newborn head circumference, no previous birth and c-section in the last delivery. Conclusions: Pathological conditions during pregnancy, newborn characteristics and women¿s reproductive characteristics were independently associated with cesarean section, but this was not observed regarding hospitals characteristics and women¿s sociodemographic characteristics. This occurred, probably because the sample was very homogeneous / Mestrado / Ciencias Biomedicas / Mestre em Tocoginecologia

Komplementäre Therapie der zervikalen Dystonie

Viehmann, Manuel Alexander 14 June 2013 (has links)
In der Behandlung der zervikalen Dystonie wird die Therapie mit Botulinumtoxin (BTX) erfolgreich angewendet. Neben dieser Therapie werden von Patienten oft alternative Therapien (CAM [Complementary and Alternative Medicine]) angesprochen und ausprobiert. Diese Studie geht der Frage nach, wie häufig CAM-Therapien genutzt werden, wie deren Wirkung bewertet wird und ob es Prädiktoren für die Therapiewahl gibt. Zur Datenerhebung wurden 265 Fragebögen von zwei Patientengruppen ausgewertet. Gruppe 1 (n=101) bestand aus Patienten der Botulinumtoxinsprechstunde des Universitätsklinikums Leipzig und der Paracelsus Klinik Zwickau. Gruppe 2 (n=165) wurde aus Mitgliedern des Selbsthilfeverbandes Bundesverband-Torticollis e.V. rekrutiert. Bei 86% der Patienten wurde die Therapie mit BTX angewendet. Von den Therapiemöglichkeiten der CAM wurden am häufigsten physikalische Therapien (Massagen n=171) genannt. Am besten bewertet wurden jedoch, neben der BTX-Therapie, spezielle physiotherapeutische sowie psychotherapeutische Verfahren. Die CAM-Therapien wurden häufig in Kombination mit der BTX-Therapie angewendet und von Patienten, deren Erkrankung einen langen chronischen Verlauf vorwies (>10 Jahre). Als Prädiktoren für die Wahl einer CAM-Therapie zeigten sich eine Zugehörigkeit zur Gruppe 2, aufgetretene Nebenwirkungen im Rahmen der BTX-Therapie, männliches Geschlecht und erhöhter Stress bei den Erkrankten. Außerdem fand sich ein signifikanter Unterschied zu einem höheren Bildungsabschnitt und Arbeit in gehobeneren Berufsgruppen bei Patienten, die vermehrt CAM Therapie anwenden. Zusammenfassend wurden CAM-Therapien, neben der Behandlung mit BTX, häufig von den Befragten angewendet. Hohe Zufriedenheitswerte erzielte eine Kombination mit physiotherapeutischen Verfahren oder Psychotherapie. Die Wahl von CAM-Therapien ist von der Erkrankungsdauer, Bildungslage und finanziellen Ressourcen abhängig.:1 EINLEITUNG 5 2 STAND DER FORSCHUNG 6 2.1 Definitionen 6 2.2 Epidemiologie 7 2.3 Pathologie 8 2.4 Klinisches Bild 11 2.5 Therapie 13 3 FRAGESTELLUNG UND HYPOTHESEN 24 4 STICHPROBE UND METHODE 25 4.1 Stichprobe 25 4.2 Erhebungsinstrument 26 4.3 Statistische Auswertung 28 5 ERGEBNISSE 30 5.1 Soziodemographische Daten 30 5.2 Krankheitsbezogene Merkmale 33 5.3 Therapie 35 5.4 Prädiktoren für die Therapiewahl 42 6 DISKUSSION 45 6.1 Das Patientenkollektiv 45 6.2 Diskussion der Botulinum-Toxin-Therapie 47 6.3 Diskussion der alternative Therapien 48 6.4 Diskussion der Prädiktoren für die Therapiewahl 54 6.5 Kritik 58 6.6 Schlussfolgerungen und Empfehlungen 59 7 ZUSAMMENFASSUNG 61 8 LITERATURVERZEICHNIS 64 9 ANLAGEN 72 9.1 Tabellen- und Abbildungsverzeichnis 9.2 Fragebogen 9.3 Erklärung der eigenständigen Abfassung der Arbeit 9.4 Curriculum Vitae 9.5 Veröffentlichungen und Vorträge 9.6 Danksagung

Minority Adult Survivors of Childhood Cancer: A Comparison of Long-Term Outcomes, Health Care Utilization, and Health-Related Behaviors From the Childhood Cancer Survivor Study

Castellino, Sharon M., Casillas, Jacqueline, Hudson, Melissa M., Mertens, Ann C., Whitton, John, Brooks, Sandra L., Zeltzer, Lonnie K., Ablin, Arthur, Castleberry, Robert, Hobbie, Wendy, Kaste, Sue, Robison, Leslie L., Oeffinger, Kevin C. 20 September 2005 (has links)
PURPOSE: To determine the influence of race/ethnicity on outcomes in the Childhood Cancer Survivor Study (CCSS). PATIENTS AND METHODS: Of CCSS adult survivors in the United States, 443 (4.9%) were black, 503 (5.6%) were Hispanic and 7,821 (86.6%) were white. Mean age at interview, 26.9 years (range, 18 to 48 years); mean follow-up, 17.2 years (range, 8.7 to 28.4 years). Late mortality, second malignancy (SMN) rates, health care utilization, and health status and behaviors were assessed for blacks and Hispanics and compared with white survivors. RESULTS: Late mortality rate (6.5%) and 15-year cumulative incidence of SMN (3.5%) were similar across racial/ethnic groups. Minority survivors were more likely to have lower socioeconomic status (SES); final models were adjusted for income, education, and health insurance. Although overall health status was similar, black survivors were less likely to report adverse mental health (females: odds ratio [OR], 0.6; 95% CI, 0.4 to 0.9; males: OR, 0.5; 95% CI, 0.3 to 0.8). Differences in health care utilization and behaviors noted: Hispanic survivors were more likely to report a cancer center visit (females: OR, 1.5; 95% CI, 1.1 to 2.0; males: OR, 1.7; 95% CI, 1.2 to 2.3); black females were more likely (OR, 1.6; 95% CI, 1.1 to 2.4), and Hispanic females less likely to have a recent Pap smear (OR, 0.7; 95% CI, 0.5 to 1.0); black and Hispanic survivors were less likely to report smoking; black survivors were less likely to report problem drinking. CONCLUSION: Adjusted for SES, adverse outcomes in CCSS were not associated with minority status. Importantly, black survivors reported less risky behaviors and better preventive practices. Hispanic survivors had equitable access to cancer related care.

Fast Food Consumption and Its Associations With Obesity and Hypertension Among Children: Results From the Baseline Data of the Childhood Obesity Study in China Mega-Cities

Zhao, Yaling, Wang, Liang, Xue, Hong, Wang, Huijun, Wang, Youfa 06 December 2017 (has links)
BACKGROUND: China has seen rapid increase in obesity and hypertension prevalence and fast food consumption over the past decade. We examined status and risk factors for Western- and Chinese fast food consumption and their associations with health outcomes in Chinese children, and examined how maternal factors were associated with child health outcomes. METHODS: Data of 1626 students aged 7-16 (11.6 ± 2.0) years and their parents in four mega-cities across China (Beijing, Shanghai, Nanjing, and Xi'an) were collected in the 2015 baseline survey of the Childhood Obesity Study in China Mega-cities. Weight, height, waist circumference, and blood pressure were measured. Food intake was assessed using questionnaire. Mixed models were used to examine the associations. RESULTS: Among the children, 11.1% were obese, 19.7% were centrally obese, and 9.0% had hypertension. Obesity prevalence was much higher in boys than in girls (15.2% vs. 6.9% and 27.4% vs. 11.7%, respectively, both P < 0.001). About half (51.9% and 43.6%) of children consumed Western and Chinese fast food, respectively, over the past 3 months. Compared to those with college or above maternal education level, those with elementary school or below maternal education level were 49% more likely to consume Western fast food (odds ratio [OR] and 95% confidence interval [CI]: 1.49 [1.10-2.03]). Chinese fast food consumption rate increased by 12% with each year of increase in child's age (OR and 95% CI: 1.12 [1.02-1.23]). No significant associations between fast food consumption and health outcomes were detected. Adjusting for Western fast food consumption, children with lower maternal education were 71% and 43% more likely to have obesity and central obesity (ORs and 95% CIs: 1.71 [1.12-2.61] and 1.43 [1.00-2.03], respectively), and maternal body mass index was positively associated with child obesity, central obesity, and hypertension (ORs and 95% CIs: 1.11 [1.06-1.17], 1.12 [1.07-1.17], and 1.09 [1.03-1.15], respectively). Results were similar when Chinese fast food consumption was adjusted for. CONCLUSIONS: The prevalence of fast food consumption, obesity and hypertension is high among children in major cities in China. Maternal factors affect child outcomes.

A interface entre psiquiatria e literatura na obra de Lima Barreto / The interface between psychiatry and literature in the work of Lima Barreto

Rachman, Sergio 19 April 2010 (has links)
INTRODUÇÃO: As humanidades médicas têm sido cada vez mais valorizadas mundialmente. No entanto, são poucos os estudos psiquiátricos nessa área no Brasil. A obra de Lima Barreto (1881-1922) reveste-se de importância para o psiquiatra pelo fato de este escritor ter tido grande contato com o meio psiquiátrico de sua época, em virtude da doença mental de seu pai e de seu quadro de alcoolismo, que motivou duas internações no Hospício Nacional de Alienados do Rio de Janeiro. Neste trabalho, procuramos relacionar a obra de Lima Barreto ao contexto histórico da psiquiatria e à sua biografia, testando ainda a hipótese de que o autor tenha apresentado declínio cognitivo expresso na elaboração de sua última obra, em virtude do alcoolismo. MÉTODOS: A obra do autor foi pesquisada, sendo analisadas as representações de doença mental. Como referencial teórico, utilizou-se os conceitos de carnavalização e de cronotopo de Mikhail Bakhtin. Foi usado, ainda, um software (WordSmith tools 3.0) para encontrar variáveis linguísticas que pudessem ter relação com declínio cognitivo do autor. RESULTADOS: Nas primeiras obras, há tendência para caracterizar a doença mental de forma idealizada ou caricatural; nas últimas, de forma mais naturalista e objetiva. Os percursos dos personagens dos últimos romances têm tendências mais fatalistas, com menor grau de mudança psicológica dos personagens, quando comparados com os romances iniciais. Com os relatos do autor sobre sua internação, tem-se acesso a uma descrição das condições do Hospício Nacional de Alienados, de seus internos e do caráter das internações. Observou-se, também, menor diversidade lexical na última obra do autor, aferido pelo software. CONCLUSÕES: A obra de Lima Barreto é uma fonte representativa para aqueles que estudam história da psiquiatria brasileira do início do século XX e fornece elementos diversos daqueles presentes em vários estudos, principalmente ligados a ideologias críticas à psiquiatria. As diferenças nas representações da doença mental no início e no fim da obra provavelmente refletem elementos biográficos e psicológicos do autor. O achado de menor diversidade lexical presente na última obra pode ter relação com declínio cognitivo do autor. / INTRODUCTION: The medical humanities have been increasingly valued worldwide. However, there are few psychiatric studies in this area in Brazil. The work of Lima Barreto (1881-1922) is important to the psychiatrist because this writer had great contact with the psychiatric medium of his time, because of his father\'s mental illness and because of his picture of alcoholism, which led him to two hospitalizations in the National Asylum for the Insane in Rio de Janeiro. In this paper we try to relate the work of Lima Barreto to the historical context of psychiatry and his biography, testing also the hypothesis that the author had cognitive decline expressed in the preparation of his latest book, due to alcoholism. METHODS: The author\'s work was investigated, and the representations of mental illness analyzed. The theoretical framework used included Mikhail Bakhtin\'s concepts of chronotope and carnivalization. It was also used a software (WordSmith tools 3.0) to find linguistic variables that could be related to cognitive decline of the author. RESULTS: In early works, there is a tendency to characterize mental illness in an idealized or caricatured way, and in the late ones, in a more naturalistic and objective way. The paths of the characters in later novels have more fatalistic tendencies, with lower levels of psychological change of the characters, when compared to the early novels. With the reports of the author on his admission in the psychiatric hospital, we have access to a description of condition of the National Asylum for the Insane, its internals and the character of admissions. It was also observed that there was less lexical diversity in the last work of the author, as measured by the software. CONCLUSIONS: Lima Barreto\'s work is a representative source for those studying the history of psychiatry of the early twentieth century and provides different elements compared to those present in several studies, mainly linked to ideologies critical to psychiatry. The differences in the representations of mental illness at the beginning and the end of the work probably reflect biographical and psychological elements of the author. The finding of lower lexical diversity present in the latest work may be related to cognitive decline of the author.
