A abolição da dupla incriminação no mandado de detenção europeu

This essay presents the European Arrest Warrant and its relationship with the principle of double criminality, which was abolished in 2002 with the new Framework Decision (FD). This instrument was essential to implement the principle of mutual recognition and strengthen the police and judicial cooperation in criminal matters in the newly created space of freedom, security and justice. It was urgent to create mechanisms to combat cross-border crime, that alone States have struggled to counter. An analysis of the FD No 2002/584/JHA is made. The execution of warrants and the non-mandatory and optional grounds of refusal are studied in detail. As it is the implementation issue. The role of mutual recognition in practice is studied as well. The procedure is to introduce the principle of double criminality, to explain the concept and its abolition, warning for the consequences derived from them, related to the principle of legality and fundamental rights. The analysis of the European Arrest Warrant in practice in Portugal and in comparison with other Member States allows the measurement of the consequences from the abolition of dual criminality and the position of States on this measure. With the abolition of double criminality, the cooperation in judicial and criminal matters departs from what was intended by the European Council of Tampere. And without cooperation, fundamental rights of citizens are unprotected, so the states have to adopt measures to remedy the "failures" of the European Law.

Prodromal Questionnaire: translation, adaptation to Portuguese and preliminary results in ultra-high risk individuals and first episode psychosis

OBJECTIVE: The Prodromal Questionnaire (PQ) is a 92-item self-report screening tool for individuals at ultra-high risk (UHR) to develop psychosis. This study aims to present the translation to Portuguese and preliminary results in UHR and first episode (FE) psychosis in a Portuguese sample. METHODS: The PQ was translated from English to Portuguese by two bilingual researchers from the research program on early psychosis of the Instituto de Psiquiatria HCFMUSP, São Paulo, Brazil (ASAS - "Evaluation and Follow up of Adolescents and Young Adults in São Paulo") and back translated by two other researchers. The study participants (n = 11-) were evaluated through the Portuguese version of the Prodromal Questionnaire (PQ) and SIPS. RESULTS: The individuals at UHR (n = 7) presented a lower score than first episode patients (n = 4). The UHR mean scores and standard deviation on Portuguese version of the PQ were: 13.0 ± 10.0 points on positive symptoms subscale, and FE patients: 33.0 ± 10.0. CONCLUSION: The UHR and FE patients' of this study presented PQ scores similar to the ones found in the literature; what suggests that it is possible to use the PQ in Brazilian help-seeking individuals as a screening tool.

Is psychodynamic psychotherapy an effective intervention for individuals at ultra-high risk (UHR) of psychosis?: a case report

OBJECTIVE: To report a case and to discuss the use of psychodynamic psychotherapy (PD-P) to treat individuals at ultra-high risk (UHR) of psychosis. METHODS: An individual at UHR was followed up for 24 months. The baseline evaluation included a psychiatric interview, the Structured Interview for Prodromal Symptoms (SIPS), the Scale of Prodromal Symptoms (SOPS), and neuropsychological assessment. He underwent weekly sessions of PD-P for 12 months and was followed up for 12 months after the end of PD-P. The evaluations were at baseline, after 6-, 12-, and 24-month follow-up. No medication was prescribed during the 24-month follow-up. RESULTS: The prodromal symptoms remitted. The initial total score on the SIPS/SOPS was 37 points. After the first 12 months of PD-P, there was a reduction to 12 points on the SIPS/SOPS score, which stabilized in the 24-month follow-up. There was also a slight improvement in his performance on the neuropsychological evaluations. CONCLUSION: This case report suggests that PD-P can reduce prodromal symptoms; nevertheless, a better understanding of the specificity and efficacy of PD-P as an option of treatment for UHR individuals is needed.

Disfunção arterial como possível mecanismo de agressão cardíaca em pacientes com diabetes mellitus tipo II. Estudo Doppler-ecocardiográfico

OBJETIVO: Avaliar a estrutura e função do ventrículo esquerdo (VE) e a rigidez arterial em portadores de diabetes mellitus tipo II. MÉTODOS: Foram estudados 13 doentes diabéticos de ambos os sexos (55±8 anos) sem outras doenças. A estrutura e função do VE foram avaliadas por meio de ecodopplercardiografia associada à monitorização não invasiva da pressão arterial (PA). Os resultados foram comparados aos obtidos em grupo de indivíduos normais de mesma idade (n=12). RESULTADOS: Não houve diferenças entre os grupos quanto a PA diastólica, dimensões das câmaras esquerdas e índices de função sistólica e diastólica. Os pacientes diabéticos apresentaram índice de massa do VE (101±10 vs 80±14g/m²; p<0,001) e índice de rigidez arterial sistêmica (0,86±0,26 vs 0,69±0,19mmHg/mL; p<0,05) significantemente maiores que os controles. CONCLUSÃO: O diabetes mellitus está associado a aumento da rigidez arterial sistêmica e esse fator poderia contribuir para seus efeitos adversos sobre o VE.

Avaliação morfo-funcional cardíaca em jovens normotensos, filhos de hipertensos. Estudo Doppler-ecocardiográfico prospectivo

OBJETIVO: Avaliar pelo Doppler-ecocardiograma alterações cardíacas, estrutural e/ou funcionais, que podem surgir nos jovens normotensos com história familiar de hipertensão arterial sistêmica (HAS). MÉTODOS: Estudo prospectivo realizado com 62 jovens normotensos entre 15 e 30 anos, sendo 32 filhos de hipertensos (grupo 1) e 30 filhos de normotensos (grupo 2) comparáveis quanto à pressão arterial, superfície corporal, freqüência cardíaca, idade e sexo. Após exame clínico, todos realizaram Doppler-ecocardiograma para avaliar as estruturas cardíacas e a função ventricular esquerda (sistólico e diastólica). RESULTADOS: A fração de encurtamento sistólico do ventrículo esquerdo (VE) foi significativamente maior no grupo 1 - valor médio de 38,03±4,95% - do que no grupo 2 - 34,7±4,48 % (p<0,01). O tempo de desaceleração mitral (TD) variou de 85 a 160ms - médio de 116,47±16,99ms - no grupo 1 e de 100 a 220ms - médio de 126,73±26,66ms - no grupo 2 (p<0,05). Houve correlação entre o índice de massa do VE e o diâmetro do átrio esquerdo (AE) no grupo 1 (r= 0,514, p<0,01). CONCLUSÃO: Os filhos de hipertensos, quando comparados com filhos de normotensos, exibem exacerbação da função sistólica do VE, semelhante ao que ocorre na fase inicial da HAS ou na HAS "borderline", mesmo que não haja hipertrofia do VE ou aumento dos níveis pressóricos. O TD mitral (mais curto no grupo 1) foi o único parâmetro de função diastólica do VE que diferiu nos 2 grupos analisados. A correlação entre o índice de massa do VE e o diâmetro do AE nos filhos de hipertensos sugere que o AE se modifica de acordo com as alterações funcionais e hemodinâmicas do VE.

Doppler echocardiographic evaluation of HIV-positive patients in different stages of the disease

OBJETIVE: To evaluate by Doppler echocardiography (DE) early abnormalities of ventricular function in HIV-positive patients, as well as other cardiac abnormalities that can be detected by this method, with special emphasis on mitral valve flow. METHODS: 84 HIV- positive patients, 59 with CD4 cell count >500/mm³ (Group A) and 25 with CD4 cell count <500/mm³ (Group B), were analyzed. CD4 cells were counted and matched with structural data and systolic and diastolic function of the left ventricle (LV), as analyzed by DE. The results were compared with those obtained in 47 healthy individuals (Group C). RESULTS: 8% of patients in Group B had mild pericardial effusion; 31.5% showed decreased systolic function of the LV, and 12% had moderate mitral regurgitation. A wave velocity from the mitral inflow was different among the 3 groups, being higher in Group B, where the deceleration time of the E wave of the mitral inflow and the E/A ratio were significantly lower with a normal value of the isovolumic relaxation time (IVRT). CONCLUSION: HIV-positive patients with a CD4 cell count >500/mm³ had no abnormalities by DE. Patients with a more advanced infection (those with a CD4 cell count <500/mm³), had a significantly abnormal LV systolic function and a higher incidence of pericardial effusion and mitral regurgitation. Mitral valve inflow by Doppler did not indicate diastolic dysfunction.

Doppler echocardiographic study in adolescents and young adults with sickle cell anemia

OBJECTIVE: Anatomical and functional assessment of the heart through Doppler and echocardiography in patients with cell anemia (SCA). METHODS: Twenty-five patients with SCA and ages ranging from 14 to 45 years were prospectively studied in a comparison with 25 healthy volunteers. All of them underwent clinical and laboratory evaluation and Doppler echocardiography as well.The measurements were converted into body surface indices. RESULTS: There were increases in all chamber diameters and left ventricle (LV) mass of the SCA patients. It was characterised an eccentric hypertrophy of the left ventricle. The preload was increased (left ventricle end-diastolic volume) and the afterload was decreased (diastolic blood pressure, peripheral vascular resistance and end-systolic parietal stress ESPS). The cardiac index was increased due to the stroke volume. The ejection fraction and the percentage of the systolic shortening , as well as the systolic time intervals of the LV were equivalent. The isovolumetric contraction period of the LV was increased. The mitral E-septum distance and the end-systolic volume index (ESVi) were increased. The ESPS/ESVi ratio,a loading independent parameter, was decreased in SCA, suggesting systolic dysfunction. No significant differences in the diastolic function or in the pulmonary pressure occurred. CONCLUSION: Chamber dilations, eccentric hypertrophy and systolic dysfunction confirm the evidence of the literature in characterizing a sickle cell anemia cardiomyopathy.

Right coronary artery fistula with congestive heart failure in the neonate. Doppler echocardiographic diagnosis and closure with detachable balloon

We report here a case of coronary artery fistula in a neonate with clinical signs of heart failure. The electrocardiogram showed signs of left ventricular hypertrophy and diffuse alterations in ventricular repolarization. Chest X-ray showed an enlargement of the cardiac silhouette with an increase in pulmonary flow. After echocardiographic diagnosis and angiographic confirmation, closure of the fistulous trajectory was performed with a detachable balloon with an early and late successful outcome.

Structural and functional characteristics of rat hearts with and without myocardial infarct. Initial experience with doppler echocardiography

OBJECTIVE: To assess by Doppler echocardiography the structural and functional alterations of rat heart with surgical induced extensive myocardial infarction. METHODS: Five weeks after surgical ligature of the left coronary artery, 38 Wistar-EPM rats of both sexes, 10 of them with extensive infarction, undergone anatomical and functional evaluation by Doppler echocardiography and then euthanized for anatomopathological analysis. RESULTS: Echocardiography was 100% sensible and specific to anatomopathological confirmed extensive miocardial infarction. Extensive infarction lead to dilatation of left ventricle (diastolic diameter: 0.89cm vs.0.64cm; systolic: 0.72cm vs. 0.33cm) and left atrium (0.55cm vs. 0.33cm); thinning of left ventricular anterior wall (systolic: 0.14cm vs. 0.23cm, diastolic: 0.11cm vs. 0.14cm); increased mitral E/ A wave relation (6.45 vs. 1.95). Signals of increased end diastolic ventricle pressure, B point in mitral valve tracing in 62.5% and signs of pulmonary hypertension straightening of pulmonary valve (90%) and notching of pulmonary systolic flow (60%) were observed in animals with extensive infarction. CONCLUSION: Doppler echocardiography has a high sensitivity and specificity for detection of chronic extensive infarction. Extensive infarction caused dilatation of left cardiac chambers and showed in Doppler signals of increased end diastolic left ventricular pressure and pulmonary artery pressure.

Congestive heart failure. Correlation between functional class and systolic and diastolic functions assessed by Doppler echocardiography

OBJECTIVE: To evaluate the influence of systolic or diastolic dysfunction, or both on congestive heart failure functional class. METHODS: Thirty-six consecutive patients with a clinical diagnosis of congestive heart failure with sinus rhythm, who were seen between September and November of 1998 answered an adapted questionnaire about tolerance to physical activity for the determination of NYHA functional class. The patients were studied with transthoracic Doppler echocardiography. Two groups were compared: group 1 (19 patients in functional classes I and II) and group 2 (17 patients in functional classes III and IV). RESULTS: The average ejection fraction was significantly higher in group 1 (44.84%±8.04% vs. 32.59%±11.48% with p=0.0007). The mean ratio of the initial/final maximum diastolic filling velocity (E/A) of the left ventricle was significantly smaller in group 1 (1.07±0.72 vs. 1.98±1.49 with p=0.03). The average maximum systolic pulmonary venous velocity (S) was significantly higher in group 1 (53.53cm/s ± 12.02cm/s vs. 43.41cm/s ± 13.55cm/s with p=0.02). The mean ratio of maximum systolic/diastolic pulmonary venous velocity was significantly higher in group 1 (1.52±0.48 vs. 1.08±0.48 with p=0.01). A predominance of pseudo-normal and restrictive diastolic patterns existed in group 2 (58.83% in group 2 vs. 21.06% in group 1 with p=0.03). CONCLUSION: Both the systolic dysfunction index and the patterns of diastolic dysfunction evaluated by Doppler echocardiography worsened with the evolution of congestive heart failure.

Contribution of Doppler echocardiography to the evaluation of systolic and diastolic function of obese women versus a control group

OBJECTIVE: To study by doppler echocardiography the cardiac systolic and diastolic functions of health, uncomplicated obese subjects. METHODS: Fifty-nine obese women with an average body mass index (BMI) of 35 kg/m² were evaluated and compared with 19 subjects with an average BMI of 23 kg/m² (control group). RESULTS: In the obese group, a clear tendency was observed toward higher systolic pressure, increased wall thickness and, consequently, myocardial mass, elevation on the circumference stress of the left ventricular wall, and an indisputable presence of diastolic abnormalities. Filling abnormalities were observed with impaired relaxation, with prolonged isovolumic relaxation time (IVRT) and augmented atrium contribution representing early indexes of cardiac dysfunction when systolic performance is still normal. CONCLUSION: Obesity is generally a chronic condition, and doppler echocardiography can be used as a noninvasive instrument for early evaluation of left ventricular diastolic indexes.
