THE RELEVANCE OF NUTRITIONAL STATUS AND HISTOPATHOLOGICAL FINDINGS ON THE INFECTIOUS PROCESS OF BALB/C MICE INOCULATED WITH Lacazia loboi

SUMMARY The aim of this study was to evaluate the effects of the protein-calorie malnutrition in BALB/c isogenic mice infected with Lacazia loboi, employing nutritional and histopathological parameters. Four groups were composed: G1: inoculated with restricted diet, G2: not inoculated with restricted diet, G3: inoculated with regular diet, G4: not inoculated with regular diet. Once malnutrition had been imposed, the animals were inoculated intradermally in the footpad and after four months, were sacrificed for the excision of the footpad, liver and spleen. The infection did not exert great influence on the body weight of the mice. The weight of the liver and spleen showed reduction in the undernourished groups when compared to the nourished groups. The macroscopic lesions, viability index and total number of fungi found in the footpads of the infected mice were increased in G3 when compared to G1. Regarding the histopathological analysis of the footpad, a global cellularity increase in the composition of the granuloma was observed in G3 when compared to G1, with large numbers of macrophages and multinucleated giant cells, discrete numbers of lymphocytes were present in G3 and an increase was observed in G1. The results suggest that there is considerable interaction between Jorge Lobo's disease and nutrition.

Is It Possible to Simplify Risk Stratification Scores for Patients with ST-Segment Elevation Myocardial Infarction Undergoing Primary Angioplasty?

INTRODUCTION: There are several risk scores for stratification of patients with ST-segment elevation myocardial infarction (STEMI), the most widely used of which are the TIMI and GRACE scores. However, these are complex and require several variables. The aim of this study was to obtain a reduced model with fewer variables and similar predictive and discriminative ability. METHODS: We studied 607 patients (age 62 years, SD=13; 76% male) who were admitted with STEMI and underwent successful primary angioplasty. Our endpoints were all-cause in-hospital and 30-day mortality. Considering all variables from the TIMI and GRACE risk scores, multivariate logistic regression models were fitted to the data to identify the variables that best predicted death. RESULTS: Compared to the TIMI score, the GRACE score had better predictive and discriminative performance for in-hospital mortality, with similar results for 30-day mortality. After data modeling, the variables with highest predictive ability were age, serum creatinine, heart failure and the occurrence of cardiac arrest. The new predictive model was compared with the GRACE risk score, after internal validation using 10-fold cross validation. A similar discriminative performance was obtained and some improvement was achieved in estimates of probabilities of death (increased for patients who died and decreased for those who did not). CONCLUSION: It is possible to simplify risk stratification scores for STEMI and primary angioplasty using only four variables (age, serum creatinine, heart failure and cardiac arrest). This simplified model maintained a good predictive and discriminative performance for short-term mortality.

Multiple Mechanical Complications in ST-Segment Elevation Myocardial Infarction with Angiographically Normal Coronary Arteries

This case report discusses an unusual presentation of ST-segment elevation myocardial infarction (STEMI) with normal coronary arteries and severe mechanical complications successfully treated with surgery. An 82-year-old man presented STEMI with angiographically normal coronary arteries and no major echocardiographic alterations at discharge. At the first month follow-up, he complained of fatigue and dyspnea, and contrast echocardiography complemented by cardiac magnetic resonance imaging revealed a large left ventricular apical aneurysm with a thrombus communicating by two jets of a turbulent flow to an aneurysmatic formation of the right ventricular apex. The patient underwent a Dor procedure, which was successful. Ventricular septal defects and ventricular aneurysms are rare but devastating complications of STEMI, with almost all patients presenting multivessel coronary artery disease. Interestingly in this case, the angiographic pattern was normal.

Contributo para o desenvolvimento de uma metodologia que avalia a posição da omoplata: fidedignidade intra e interobservador e validade concorrente

RESUMO: Introdução: A relação cinemática entre as articulações do CAO apresenta grande importância na função do MS, e é por isso cada vez mais investigada e descrita. O posicionamento da omoplata ganha um importante papel para compreender as DCAO. É indiscutível o importante papel da omoplata na dinâmica do MS, bem como o posicionamento escapular como parâmetro clínico de disfunção do CAO. Todos estes factores criam a necessidade de desenvolver instrumentos de avaliação da posição da articulação ET. A grande maioria dos testes de avaliação, restringem a sua avaliação às disfunções da articulação GU, não integrando uma avaliação mais dinâmica e interactiva que respeite os pressupostos teóricos inerentes ao REU. È importante também que os métodos de avaliação sejam de fácil aplicabilidade clínica e que avaliem fidedignamente e com validade os outcomes. Objectivos: Contribuir para o desenvolvimento de uma metodologia de avaliação da omoplata em diferentes amplitudes do MS, através do estudo da validade concorrente, da fidedignidade intra e inter-observador. Metodologia: A amostra foi constituída por 20 elementos seleccionados por conveniência, entre o corpo de discentes da ESS-IPS, sem história de disfunção do CAO. Foi realizada uma análise cinemática ao MS de cada sujeito, usando um aparelho de análise por varrimento electromagnético, o FOB. Em cada sujeito foram ainda medidas, as distâncias escapulares em estudo, usando a fita métrica. Cada método de medição foi constituído por dois momento (teste e reteste), em cada momento, as medidas eram recolhidas por dois investigadores distintos. Resultados e Discussão: Foram considerados como positivos os resultados que se apresentassem acima do limiar de 0,5, que classifica uma correlação como moderada a excelente. Os resultados da validade mostram que para o investigador 1 nas medidas M1e M2 apenas houve correlação com valores excelentes a moderados até aos 30º de elevação do MS. Já para M3 apenas aos 30º no plano da omoplata essa mesma correlação não tem valores próximos do cutpoint. Em M4 nenhum valor tem correlação significativa com os valores do FOB, chegando mesmo a haver correlação negativa para os 120º no plano da omoplata. Em M5 apenas os 0º mostram valores correlacionais excelentes a moderados. Para o investigador 2, em M1 e M2 á semelhança do investigador 1, só existem valores de correlação significativos até aos 30º de elevação do MS. Já para M3 todos os valores mostram excelente a moderada correlação á excepção dos 120º no plano frontal. Em M4 este investigador apresenta maus resultados. Já em M5 os valores de correlação são moderados aos 0º e aos 90º. No que diz respeitos aos resultados dos CCI intra-observador,podemos afirmar que foi em M5 que estes valores mais se aproximaram do cut point. M1 e M2 são as medidas onde se encontram resultados menos satisfatórios. É aos 60º que existem valores mais satisfatórios, seguidos pelos 0º e 30º, quando nos aproximamos de graus mais elevados, como 90º e 120º, estes valores tendem a baixar. Quanto á fidedignidade inter-observador para M1 apenas aos 90º e aos 120º houve valores de correlação abaixo do cutpoint. Em M2, só os 60º do plano sagital não teve valores acima do cutpoint, em M3 apenas os 30º plano sagital não obtiveram valores acima do cut-point, o mesmo acontece para M3 aos 30º plano da omoplata e em M5 aos 30º e 120º no plano frontal. Conclusão: Os resultados deste estudo indicam que a metodologia em causa apresenta elevado grau de fidedignidade inter-observador, já no que toca é fidedignidade intra-observador o grau de semelhança não é tão elevado. Também o erro associado á medida não ultrapassou 1,5cm, sendo considerado baixo. Na validade concorrente concluímos que é aos 0º que a metodologia se torna uma opção válida na aferição das distâncias medidas com uma boa a excelente concordância com o FOB. As medidas consideradas como opções válidas, nas diferentes amplitudes, podem funcionar como parâmetros clínicos de caracterização do posicionamento da omoplata, podendo vir a contribuir ainda para a caracterização da orientação da mesma.-------------------- ABSTRACT:Introduction: The kinematic relationship between the joints of the CAO has great importance in the function of MS, which is why more and more investigated and described. The positioning of the blade gets an important role in understanding the DCAO. There is no doubt the important role of the scapula in the dynamics of MS as well as the positioning of scapular dysfunction as a clinical parameter of the CAO. All these factors create the need to develop tools for evaluating the place of articulation ET. Most assessment tests, restrict its assessment to GU joint disorders, not incorporating a more dynamic and interactive way that respects the theoretical assumptions inherent in the REU. It is also important that the methods are easy to apply clinical and reliably to assess the validity and outcomes. Objectives: To contribute to the development of a methodology for evaluating the scapula in different ranges of MS, through the study of concurrent validity, reliability of intra-and inter-observer. Methodology: The sample consisted of 20 selected elements for convenience, between the body of students of IPS-ESS with no history of dysfunction of the CAO. We performed a kinematic analysis of each subject to MS, using a scanning device for electromagnetic analysis, the FOB. In each subject were also measured, the scapular distances under study, using tape measure. Each method of measuring the time consisted of two (test and retest), in each moment, the measures were collected by two different investigators. Results and Discussion: We considered as positive results that were above the threshold of 0.5, which ranks as a moderate to excellent correlation. The results show that the validity for the researcher in an action M1e M2 was only correlated with moderate to excellent values up to 30º of elevation of the MS. As for M3 only to 30º in the plane of the scapula has the same correlation values near the cutpoint. M4 has no value in correlation with the values of the FOB, and even negative correlation to 120 ° in the plane of the scapula. In M5 show only the values 0 ° correlational excellent to moderate. For investigator 2 in M1 and M2 will be like an investigator, there are only significant correlation values up to 30º of elevation of the MS. As for M3 all the values show excellent correlation to moderate with the exception of 120 ° in the frontal plane. In this researcher M4 has bad results. M5 already in the correlation values are moderate to 0º and 90 º. Regarding the results of ICC intra-observer, we can say that M5 was that these values come closest to the cut point. M1 and M2 are measures which are less than satisfactory results. At 60 ° there are more satisfactory values, followed by 0º and 30º, when we approached the highest levels, such as 90 ° and 120 °, these values tend to decrease. The inter-observer reliability for M1 only to 90 º and 120 ºcorrelation values were below the cutpoint. In M2, only 60 of the sagital plane did not have values above the cutpoint in M3 only 30º sagital plane did not obtain values above the cut-point, the same goes for M3 at 30 ° plane of the scapula and M5 at 30 º and 120 º in frontal plane. Conclusion: The results of this study indicate that the methodology in question has a high degree of inter-observer reliability, as far as intra-observer reliability is the degree of similarity is not as high. Also the error of measure did not exceed 1.5 cm, and is considered low. In concurrent validity conclude that it is at 0 ° the methodology becomes a valid option for the measurement of distances measured with a good to excellent agreement with the FOB. The measures considered as valid options in different amplitudes, can function as clinical parameters to characterize the positioning of the shoulder blade and could further contribute to the characterization of the orientation of the same.

Levonorgestrel Intrauterine Device Effectiveness in Heavy Menstrual Bleeding Treatment in Obese Women

Objective:We aimed to identify if there was any difference in Levonorgestrel-releasing intrauterine system (LNG-IUS) efficacy or weight gain when used in heavy menstrual bleeding (HMB) treatment, between obese and non-obese women. Population and methods: This was a case-controlled retrospective study undertaken between 2002-2007. 194 women with HMB were treated with LNG-IUS and stratified into two groups accordingly with body mass index (BMI): Obese Group – BMI ≥ 30 (n=53) and Non-obese Group – BMI < 30 (n=141). Age, weight, days of spotting and days of menses were analyzed at 1, 3 and 6 months after insertion and then annually until 2 years. Analytic parameters of anemia (hemoglobin, serum ferritin, mean corpuscular volume) were reviewed at pre-insertion, at 6 months and then annually until 2 years. Results: During the 2-year follow-up there was a similar improvement in two groups regarding duration of menses, spotting and in analytic parameters of anemia. A statistically significant improvement was observed in obese group after 2 years of treatment regarding analytic parameters of anemia and menstrual characteristics, without weight gain. Conclusion: In obese women, the LNG-IUS is an effective treatment for heavy menstrual bleeding, without being associated to weight gain.

Caracterização da aterosclerose sub-clínica e doença coronária em doentes com síndrome metabólica e diabetes mellitus

RESUMO- Introdução: A obesidade e a Síndrome Metabólica (SM) são atualmente um importante problema de saúde pública, com prevalências crescentes, que se acompanham também por aumento da prevalência de Diabetes Mellitus (DM).Estudos prévios demonstram associação destas entidades com o aumento de risco de eventos cardiovasculares, em particular a DM. A SM tem sido uma entidade muito debatida nos últimos anos, com aparecimento de diversas definições, contribuindo para resultados díspares no que diz respeito à influência da SM nas doenças cardiovasculares. Também têm sido descritas variações étnicas e regionais. Para além de alguns estudos epidemiológicos na população geral, a informação relativamente à sua influência na presença de doença cardiovascular é desconhecida em Portugal, em particular em populações com suspeita de doença coronária. Objetivos - Esclarecimento de questões relacionadas com a prevalência de SM e a sua influência na evolução de doença ateroclerótica arterial por avaliação de uma população com suspeita de doença coronária. População e Métodos - Estudo observacional, transversal, com inclusão prospetiva de indivíduos admitidos letivamente para realização de angiografia coronária por suspeita de doença coronária, tendo sido também efetuadas análises laboratoriais e ecografia carotidea para avaliação da espessura intima-média carotidea (EIMc) e da presença de placas carotídeas. Efetuou-se avaliação dos parâmetros demográficos, antropométricos, determinação do perfil lipídico, glicémia e insulinémia. Os exames angiográficos foram analisados por análise quantitativa semi-automática. Foram excluídos indivíduos com antecedentes conhecidos de doença cardíaca. Resultados - Incluíram-se 300 doentes, com idade média de 64 ± 9 anos, 59% do género masculino. A prevalência de SM de acordo com a definição da AHA/NHLBI foi 48,4% (ajustada para idade e género da população portuguesa) e a prevalência de DM foi 14,8% (ajustada). A concordância global das três definições mais recentes de SM foi de apenas 43%. A prevalência de SM aumenta com a idade e é também mais elevada no género feminino. O componente mais frequente foi a hipertensão arterial, seguido pela obesidade abdominal, a elevação da glicémia e por fim as alterações dos triglicéridos e do colesterol HDL. Por outro lado, a presença de doença coronária significativa (lesões ≥50%) ocorreu em apenas 51,3% dos doentes, sendo ainda mais baixa no género feminino. Demonstrou-se também uma baixa capacidade preditiva para doença coronária dos testes não invasivos clássicos, em particular no género feminino. A prevalência de doença coronária significativa foi idêntica nos indivíduos com SM comparativamente com indivíduos sem alterações metabólicas (46,3% vs. 48,2%, respectivamente), sendo mais elevado nos diabéticos (65,2%). Os fatores predizentes independentes de doença coronária significativa foram a idade, o género masculino, a elevação da glicémia e dos triglicéridos. Pelo contrário, o Índice de Massa Corporal (IMC) mostrou uma associação protetora relativamente à presença de doença coronária. A SM não é fator predizente de doença coronária. Relativamente às dimensões dos vasos coronários, o IMC correlaciona-se positivamente e a glicémia / DM correlacionam-se negativamente. A EIMc aumenta com o aumento da idade e no género masculino. A EIMc foi intermédia nos doentes com SM (0,88 ± 0,31 mm) comparativamente com os doentes diabéticos (0,97 ± 0,34 mm) e os indivíduos “Normais” (0,85 ± 0,34 mm). Os fatores predizentes independentes de EIMc foram a idade, o género masculino, o colesterol HDL e a insulinémia. A EIMc permite predizer com uma acuidade moderada a presença de doença coronária significativa (AUC 0,638), em particular no género feminino, sendo um fator predizente independente de presença de doença coronária (OR 2,35, IC 95% 1,04-5,33. p=0,04). Apesar de não se correlacionar com o número de vasos coronários com doença, correlacionou-se com a gravidade da doença (pelo score de Gensini). A insulinémia e o índice HOMA aumentam diretamente com a idade e com o IMC, sendo contudo sobreponíveis em ambos os géneros. Os fatores predizentes de índice HOMA (resistência à insulina) foram o IMC, bem como os restantes componentes de SM, estando o índice HOMA relacionado com a presença de SM e o número dos seus componentes presentes. O limiar para resistência à insulina foi de 2,66 e para SM foi 2,41. Ao contrário das restantes definições de SM, a definição da AHA/NHLBI não é predizente da presença de DM no género masculino. A associação da resistência à insulina com doença coronária foi limiar (OR 1,13, IC 95% 1,00-1,28, p=0,045). Conclusões - Numa população com suspeita de doença coronária, a prevalência de SM é muito elevada (superior a 50%), sendo a prevalência de DM de 23%. Também a obesidade e o excesso de peso foram extremamente prevalentes nesta população. A concordância entre definições de SM é baixa. A hipertensão arterial e a obesidade abdominal são os componentes mais frequentes de SM, sendo menos prevalentes as alterações lipídicas. Pelo contrário, a presença de doença coronária significativa foi muito baixa, em particular nas mulheres. A SM não se associou à presença de doença coronária significativa, estando esta mais dependente das alterações do metabolismo glicídico e dos triglicéridos, bem como de outros fatores de risco não modificáveis, nomeadamente a idade e o género. A EIMc da carótida comum e a presença de placas carotídeas é mais elevada nos indivíduos diabéticos, estando também ligeiramente aumentada nos doentes com SM, sendo os fatores predizentes de EIMc apenas a idade, o género, a hiperinsulinémia bem como os níveis baixos de colesterol HDL. A utilização da avaliação da EIMc na estratificação de risco pré-angiografia coronária, poderá ser útil no género feminino. A hiperinsulinémia e o índice HOMA (índice de resistência à insulina), estão relacionados com o IMC e consequentemente com a presença de obesidade, embora também se correlacione de forma independente com os outros componentes de SM. A resistência à insulina associou-se à presença de SM. Relativamente à capacidade preditiva da coexistência com DM, verificou-se associação com a definição da NCEP-ATP III e da IDF, contudo, a definição da AHA/NHLBI só foi predizente de DMnas mulheres. -------------ABSTRACT - Introduction: Obesity and Metabolic Syndrome (MS) are a major public health problem, with increasing prevalence, that follows the increase in diabetes prevalence. Previous studies showed an association of both entities with increased cardiovascular risk, particularly diabetes. MS has been debated in the last few years, with several definitions and different results when analysed the influence of MS on cardiovascular diseases. There are also some regional and ethnical variations. Beyond general population epidemiological studies, information about the influence on cardiovascular disease in Portugal is unknown, particularly in patients with suspected coronary disease. Objectives- To clarify several questions regarding the prevalence of MS and the influence in arterial atherosclerotic disease by evaluation of a population with suspected coronary artery disease. Population and Methods- Observational, cross-sectional study with prospective inclusion of individuals admitted electively for coronary angiography with suspicion of coronary artery disease. All individuals also performed laboratorial evaluation and carotid ultrasound to evaluate carotid intima-media thickness (cIMT) and carotid plaques. We also evaluated demographic, anthropometric parameters, lipid profile, blood glucose and blood insulin. Angiographic data was obtained by semi-automated quantitation. Individuals with previously known cardiac history were excluded from the study. Results- We included 300 individuals with a mean age of 64 ± 9 years, 59% males. MS prevalence according to AHA/NHLBI definition was 48.4% (adjusted for age and gender of the Portuguese population) and the adjusted prevalence of diabetes was 14.8%. Global agreement between the more recent three definitions of MS was only 43%. MS prevalence increases with age and is also higher in women. The most frequent components were hypertension and abdominal obesity, followed by elevated glucose and triglicerides and low HDL-cholesterol. Significant coronary artery disease (stenosis ≥50%) was present in only 51.3% of patients, being lower in females. Non-invasive tests also had a low predictive capacity, particularly in females. The prevalence of significant coronary disease was identical in patients with MS compared with normal metabolism individuals (46.3% vs. 48.2%, respectively), being higher in diabetics (65.2%). Independent predictive factors for coronary disease were age, male gender, high blood glucose and triglycerides. On the contrary, Body Mass Index (BMI) was a protective factor for coronary disease. MS wasn’t a predictor of coronary disease. BMI showed a positive correlation with coronary vessel diameter and glucose /diabetes had a negative correlation. CIMT increased with age and was higher in males. CIMT was intermediate in patients with MS (0.88 ± 0.31 mm) when compared to diabetic patients (0.97 ± 0.34 mm) and “Normal” individuals (0.85 ± 0.34 mm). Independent predictors for cIMT were age, male gender, HDL-cholesterol and insulin. CIMT had a moderate predictive accuracy for coronary disease (AUC 0,638), particularly in females and is an independent predictor of the presence of significant coronary disease (OR 2.35, 95% CI 1.04-5.33. p=0.04). Although it did not correlate with the number of diseased coronary arteries, it correlated with coronary disease severity by the Gensini score. Insulin and HOMA index increase directly with age and BMI, but were identical in both genders. Predictive factors for HOMA index (insulin resistance) were BMI as well as the other MS components. HOMA index is related to MS and the number of its components. The cut-off for insulin resistance was 2.66 and for MS 2.41. Unlike other MS definitions, AHA/NHLBI definition is not a predictor of diabetes in males. There was a borderline association between insulin resistance and coronary disease (OR 1.13, 95% CI 1.00-1.28, p=0.045). Conclusions - In a population of patients with suspected coronary disease, MS prevalence is extremely high (above 50%) with a diabetes prevalence of 23%. Also obesity and overweight are very prevalent in this population. Global agreement between MS definitions is however low. Hypertension and abdominal obesity are the most frequent components, with a lower prevalence of lipid abnormalities. Coronary disease prevalence was low, particularly in women. MS wasn’t associated with coronary disease. Coronary disease was related to glucose and triglycerides, as well as with other non-modifiable factors such as age and gender. CIMT and carotid plaques are increased in diabetic patients, and also slightly elevated in patients with MS, but cIMT independent predictors were age, male gender, insulin and HDLcholesterol. CIMT can be useful in risk stratification before coronary angiography particularly in women. Elevated insulin and HOMA index (an insulin resistance index) are related with BMI and consequently with obesity, and it was also correlated with other MS components. Insulin resistance was associated with MS. The presence of diabetes was associated with the presence of MS by NCEP-ATP III and IDF definitions; however, AHA/NHLBI definition was only predictive of diabetes in females.

Liver and serum soluble protein changes and pathomorphology in undernourished mice with acute Schistosomiasis mansoni

Body, liver and spleen weights; histopathology of the liver, spleen and intestines; hepatic and serum soluble proteins changes were the parameters studied in undernourished Swiss albino mice experimentally infected with S. mansoni. Non-infected deficient animab had lower liver/body weight and spleen/body weight ratios as compared to the controls (22.60% casein group). Infected mice showed higher values regardless the type of diet. Undernourished infected subgroup showed a persistent exudative periovular reaction in the liver. Soluble hepatic proteins content and serum protein fractions appeared to be lower in the deficient infected mice. A significant difference was detected in the gammaglobulin fraction between infected and non-infected animals fed the control diet with higher values for the former. Our data suggest that the effects of malnutrition, per se, are sometimes more detrimental to the host than those due to Manson 's schistosomiasis.

The influence of the regional basic diet from northeast Brazil on health and nutritional conditions of mice infected with Schistosoma mansoni

Protein nutritionalstatus indicators were studied in weanling albino Swiss mice infected with S. mansoni andfed the Regional Basic Diet (RBD)from Northeast Brazil, a multideficient diet of low-protein content. Each mouse was infected percutaneously with 80 cercariae. The experiment lasted 63 days. The growth curve, food consumption, protein intake, weight gain, Protein Efficiency Ratio (PER) and Net Protein Ratio (NPR) were the parameters investigated. RBD-fed mice showed a marked weight loss, a lower food and protein intake, a slower body weight gain and lower rates of food protein utilization when compared to casein-fed animals. Differences between infected and non-infected mice were not consistent. The present results suggest that the effects of RBD-induced malnutrition on health and nutritional conditions of the mice are more severe than those of Manson's schistosomiasis, in the initial phase of the disease.

Body and transcendence in Virginia Woolf and Clarice Lispector = Corpo e transcendência em Virgínia Woolf e Clarice Lispector

Virginia Woolf and Clarice Lispector belong to quite different historical, political and cultural contexts. Beyond its antecedents and roots in European modernism, Brazilian modernism developed according to peculiar patterns and lines, cultivating, for example, more clearly political, nationalist and regionalist tendencies than happened in the British area. Molly Hite’s essay “Virginia Woolf’s Two Bodies” suggests the existence of two kinds of body represented and perhaps experienced by Virginia Woolf: “one kind was the body for others, the body cast in social roles”, the other, the “visionary body”, a second physical presence, which brings into play new perspectives on the female modernist body and new strategies of political and aesthetic representation. It is this “visionary body”, that, in many moments, intersects with transcendence. These two kinds of body are also present in Clarice Lispector’s work, structured, of course, around other complexities and gradations, explained by a different temporal context, but still touching common seminal questions. In Lispector, it is through the body cast in social roles that you reach the “visionary body” and transcendence. The movement is not a flight, as in Woolf, on the contrary it is a necessity, a condition to get to the essence.
