Insatisfação com a imagem corporal em universitárias brasileiras

A insatisfação com a imagem corporal é avaliada por meio da diferença entre a figura real e a idealizada e pode influenciar comportamentos alimentares. OBJETIVO: Avaliar a insatisfação corporal de universitárias do sexo feminino nas cinco regiões do país e possíveis associações e correlações com a idade, o estado nutricional, a renda e o grau de escolaridade do chefe da família. MÉTODOS: 2.402 universitárias responderam à Escala de Silhuetas de Stunkard. As regiões foram comparadas por meio da análise de variância; correlações entre as variáveis foram analisadas pelos coeficientes de Pearson e Spearman. RESULTADOS: 64,4% gostariam de ser menores do que sua figura atual, e mesmo as estudantes eutróficas escolheram figuras saudável e ideal menores. Na região Norte foram apontados os mais magros padrões ideais e de saúde e na região Centro-Oeste, os maiores. CONCLUSÃO: A ocorrência de insatisfação corporal foi bastante expressiva, com algumas diferenças regionais e sociodemográficas que devem ser consideradas.

Lower NPAS3 expression during the later stages of abnormal lung development in rat congenital diaphragmatic hernia

Purpose Congenital diaphragmatic hernia (CDH) is characterized by a developmental defect in the diaphragm, pulmonary hypoplasia and pulmonary hypertension. NPAS3 is a PAS domain transcription factor regulating Drosophila tracheogenesis. NPAS3 null mice develop pulmonary hypoplasia in utero and die after birth due to respiratory failure. We aimed to evaluate NPAS3 expres- sion during normal and abnormal lung development due to CDH. Methods CDH was induced by administering 100 mg/ml nitrofen to time-pregnant dams on embryonic day (E) 9 of gestation. Lungs were isolated on E15, E18 and E21 and NPAS3 localization was determined by immunohisto- chemistry and quantified using Western blotting. Results We found that only E21 hypoplastic CDH lungs have reduced expression of NPAS3 in the terminal sac- cules. Western blotting confirmed the down-regulation of NPAS3 protein in the nitrofen-induced hypoplastic lungs. Conclusions We demonstrate for the first time that ni- trofen-induced hypoplastic CDH lungs have reduced NPAS3 expression in the terminal saccules during the later stages of abnormal lung development. Our findings suggest that NPAS3 is associated with pulmonary hypoplasia in CDH.

Redefining the MED13L syndrome

Congenital cardiac and neurodevelopmental deficits have been recently linked to the mediator complex subunit 13-like protein MED13L, a subunit of the CDK8-associated mediator complex that functions in transcriptional regulation through DNA-binding transcription factors and RNA polymerase II. Heterozygous MED13L variants cause transposition of the great arteries and intellectual disability (ID). Here, we report eight patients with predominantly novel MED13L variants who lack such complex congenital heart malformations. Rather, they depict a syndromic form of ID characterized by facial dysmorphism, ID, speech impairment, motor developmental delay with muscular hypotonia and behavioral difficulties. We thereby define a novel syndrome and significantly broaden the clinical spectrum associated with MED13L variants. A prominent feature of the MED13L neurocognitive presentation is profound language impairment, often in combination with articulatory deficits.

Capacidade funcional máxima e função diastólica em portadores de cardiomiopatia chagásica sem insuficiência cardíaca congestiva

OBJETIVO: Identificar disfunções cardíacas precoces em pacientes assintomáticos com cardiomiopatia chagásica. MÉTODOS: Foram estudados 38 indivíduos masculinos, sendo o grupo controle constituído de 20 indivíduos sedentários normais e o grupo Chagas de 18 pacientes assintomáticos, portadores da doença de Chagas, com eletrocardiograma alterado e fração de encurtamento (DD) normal ao ecocardiograma. Ambos os grupos foram submetidos à avaliação da capacidade funcional máxima, com medidas do consumo máximo de oxigênio (VO2max), índice de pulso de oxigênio (PO2max), ventilação máxima (VE max), freqüência cardíaca máxima (FC max), e limiar anaeróbio do VO2max (LA-VO2). A função diastólica do ventrículo esquerdo foi avaliada pelo ecocardiograma convencional (ondas E e A além da relação E/A). RESULTADOS: Não ocorreram diferenças significativas entre os dois grupos em relação ao DD (p=0,212) e a idade média (p=0,060). Houve diferença significativa (p<0,001) em relação aos parâmetros VO2max, PO2max, VE max, FC max, LA-VO2, onda E e relação E/A. Não houve significância (p=0,520) em relação a onda A. CONCLUSÃO: O comprometimento na função ventricular pode contribuir para as diferenças acima mencionadas, como conseqüência de disfunção sistólica e diastólica.

Valor da biópsia de pericárdio no diagnóstico etiológico das pericardiopatias

OBJETIVO: Determinar o valor da biópsia no diagnóstico etiológico de derrames pericárdicos. MÉTODOS: Foram analisados, retrospectivamente, de 1990 a 1997, 38 pacientes com derrame pericárdico, com idades variando de 3 meses a 79 anos (média 41,15± 21,78 anos). Todos os pacientes foram submetidos a biópsia pericárdica, tendo como acesso a via subxifóide. RESULTADOS: A biópsia foi positiva em quatro (10,5%) casos, dois de etiologia tuberculosa e dois neoplásica (um adenocarcinoma indeterminado e um mesotelioma); no restante o diagnóstico foi de pericardite crônica inespecífica. CONCLUSÃO: Em nossa casuística a biópsia não foi um método eficaz para o diagnóstico etiológico dos derrames pericárdicos. Acreditamos que a indicação de biópsia pericárdica deva ser individualizada, especificamente nos casos de suspeita de etiologia neoplásica ou tuberculosa.

Doenças cardiovasculares observadas durante o seguimento de um grupo de pacientes na forma indeterminada da doença de Chagas

OBJETIVO: Observar, num grupo de pacientes na forma indeterminada da doença de Chagas, o aparecimento de doenças cardiovasculares e sua possível relação com a doença de base. MÉTODOS: Foram seguidos, prospectivamente, 160 pacientes por até 177 meses com avaliações clínicas trimestrais. RESULTADOS: Tornaram-se hipertensos 23 (14,4%) pacientes, sendo 21 (13,2%) com pressão arterial diastólica <110mmHg. Duas pacientes (1,2%) hipertensas tiveram acidente vascular cerebral isquêmico (AVCI). Uma (0,6%) paciente teve hemorragia meníngea por ruptura de aneurisma cerebral. Quatro (2,4%) pacientes apresentaram arritmia clinicamente, dois (1,2%) extra-sístoles ventriculares, um (0,6%) extra-sístoles supraventriculares e um (0,6%) fibrilação atrial aguda. Dois (1,2%) pacientes desenvolveram coronariopatia comprovada angiograficamente, um (0,6%) com infarto agudo do miocárdio, outro com angina estável. Um (0,6%) paciente desenvolveu sinais e sintomas de insuficiência cardíaca, juntamente com o aparecimento de hipertensão arterial sistêmica (HAS). CONCLUSÃO: A doença cardiovascular mais freqüente foi a HAS. Duas hipertensas apresentaram AVCI. As arritmias observadas não foram mais freqüentes que na população normal e a coronariopatia também ocorreu raramente, confirmando um bom prognóstico clínico a longo prazo desse grupo de pacientes.

Neoplastic pericardial disease. Analysis of 26 patients

PURPOSE: To characterize patients with neoplastic pericardial disease diagnosed by clinical presentation, complementary test findings, and the histological type of tumor. METHODS: Twenty-six patients with neoplastic pericardial disease were retrospectively analyzed. RESULTS: Clinical manifestations and abnormalities in chest roentgenograms and electrocardiograms were frequent, but were not specific. Most patients underwent surgery. There was a high positivity of the pericardial biopsy when associated with the cytological analysis of the pericardial liquid used to determine the histological type of the tumor, particularly when the procedure was performed with the aid of pericardioscopy. CONCLUSION: The correct diagnosis of neoplastic pericardial disease involves suspicious but nonspecific findings during clinical examination and in screen tests. The suspicious findings must be confirmed through more invasive diagnostic approaches, in particular pericardioscopy with biopsy and cytological study.

Primary neoplasms of the heart. Clinical and histological presentation of 50 cases

OBJECTIVE: To analyze clinical and histologic findings of 50 patients with primary neoplams of the heart in a tertiary referral center. METHODS: From 1980 to 1998, we retrospectively analyzed 50 patients, 32 of whom were females, whose ages ranged from 9 to 73 years (mean age = 44.16±18 years). RESULTS: Most tumors were located in the left side of the heart (72%), myxoma being the most common (84%) histologic type. The other histologic types found were as follows: fibroma (4%), lipoma (2%), rhabdomyosarcoma (2%), hemangioma (2%), sarcoma (2%), angiosarcoma (2%), and lymphoma (2%). Diagnosis was established by echocardiography in 94% of the cases. Clinical findings were as follows: dyspnea (36%), weight loss (20%), palpitations (18%), chest pain (16%), fever (8%), and arthralgia (6%). All patients with thromboembolic phenomena (10%) had left atrial myxoma. Approximately 20% of the patients were asymptomatic at the initial clinical assessment. CONCLUSION: Primary cardiac tumors are a rare entity with diverse clinical and histologic findings, requiring, therefore, a high level of clinical suspicion.

Cholesterol pericarditis. A specific but rare cause of pericardial disease

During a diagnostic investigation in a 40-year-old male with pericardial effusion associated with hypothyroidism, cholesterol pericarditis was detected. We report a brief review on the etiopathogeny, clinical findings, and therapeutical possibilities of this entity.

Chagas' heart disease: evolutive evaluation of electrocardiographic and echocardiographic parameters in patients with the indeterminate form

OBJECTIVE: To identify and associate potential electrocardiographic and echocardiographic changes in patients with the indeterminate form of Chagas' disease during long-term follow-up. METHODS: One hundred sixty patients underwent standard electrocardiography and two-dimensional guided M-mode echocardiography for left ventricular ejection fraction determination. Patients were followed up for 98.6±30.4 months, undergoing repeat electrocardiographic studies at 6-month intervals and echocardiographic studies at 12-month intervals. RESULTS: Based on the electrocardiographic findings, the patients were divided into group I, 125 patients (78.6%) with normal electrocardiograms throughout follow-up, and group II, 34 patients (21.3%) who developed electrocardiographic changes. Group II was further divided into group IIA (9 patients, 5.6%) with permanent electrocardiographic changes, group IIB (14 patients, 8.8%) with transitory electrocardiographic changes, and group IIC (11 patients, 6.9%) with changes appearing only on the final electrocardiogram. Left ventricular ejection fractions remained normal in the entire population studied and did not differ among groups. CONCLUSION: The indeterminate form of Chagas' disease clearly represents a benign condition with a favorable long-term prognosis. Although some patients develop electrocardiographic changes, left ventricular systolic function is well preserved.

Video-assisted pericardioscopy. How to improve diagnostic efficacy in pericardial effusions

OBJECTIVE: To assess, in a prospective way, the experience with video-assisted pericardioscopy obtained in patients with pericardial effusion of unclear etiology in the preoperative period. METHODS: From January 1998 to June 2000, 20 patients were operated upon with the aid of video-assisted pericardioscopy. On echocardiography, 17 of these patients had significant pericardial effusion, and 3 had moderate pericardial effusion. Video-assisted pericardioscopy was performed through a small incision of the Marfan type. RESULTS: The diagnosis of pericardial effusion was established as follows: idiopathic in 9 (45%) patients, neoplastic in 4 (20%), resulting from hypothyroidism in 3 (15%), tuberculous in 2 (10%), due to cholesterol in 1 (5%), and chylopericardial in 1 (5%). The biopsy was positive in 30% of the patients, and the etiology could not be defined in 45% of the patients. CONCLUSION: Video-assisted pericardioscopy proved to be a method with low morbidity and a high index of diagnostic positivity. A high percentage of pericardial effusions are caused by viral infections, which are not diagnosed through current methods, being, therefore, classified as idiopathic.

Massage therapy reduces pain in pregnant women, alleviates prenatal depression in both parents and improves their relationships

Prenatally depressed women (N=47) were randomly assigned to a group that received massage twice weekly from their partners from 20 weeks gestation until the end of pregnancy or a control group. Self-reported leg pain, back pain, depression, anxiety and anger decreased more for the massaged pregnant women than for the control group women. In addition, the partners who massaged the pregnant women versus the control group partners reported less depressed mood, anxiety and anger across the course of the massage therapy period. Finally, scores on a relationship questionnaire improved more for both the women and the partners in the massage group. These data suggest that not only mood states but also relationships improve mutually when depressed pregnant women are massaged by their partners.

Partner relationships during pregnancy in anxious and depressed women and men

To assess anxiety, depression and relationship satisfaction in both women and men during pregnancy, the State Anxiety Inventory (STAI), The Center for Epidemiological Studies-Depression Scale (CES-D) and The Relationship Questionnaire (RQ) were administered during the second trimester to a sample of 59 pregnant women and their partners. Anxious pregnant women rated their relationships as less positive. Depressed pregnant women also rated their relationships as less positive. The women’s anxiety scores were predictive of their positive and negative relationship scores. The women and their partners’ negative relationship scores were also predictive of each others’ negative relationship scores. These results highlight the importance of targeting anxiety as well as depression, and pregnant women as well as their partners in prenatal intervention programs.
