- ItemSomente MetadadadosComparison of the body mass index to other methods of body fat evaluation in ethnic Japanese and Caucasian adolescent girls(Nature Publishing Group, 2001-03-01) Sampei, Miriam Akemi [UNIFESP]; Novo, Neil Ferreira [UNIFESP]; Yuliano, Y.; Sigulem, Dirce Maria [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)OBJECTIVE: the aim of this study was to assess the body mass index (BMI) and its relationship with other methods of body fat evaluation in pre- and post-menarcheal, Japanese and Caucasian female adolescents, using hive different cut-off points for obesity: 28% and 30%.DESIGN: A cross-sectional study with incomplete sampling, using the subject as the evaluation unit.SUBJECTS: A total of 436 Japanese and Caucasian female adolescents in two age groups: 10-11 (pre-menarcheal adolescent); and 16-17 (post-menarcheal adolescents).METHODS: for the BMI the cut-off point for thinness was set at the 5th percentile of the BMI distribution of the NCHS reference population and the cut-off point for overweight and obesity was set at the 85th percentile. Body composition was assessed using foot-to-foot bioelectrical impedance analysis (BIA), near-infrared interactance (NIR) and Slaughter skinfold equations (SKI). the statistical comparison of the methods was performed using the kappa agreement test and the McNemar disagreement test.RESULTS: in the 10- and 11-y-old girls, the BMI was considerably and significantly correlated with the other methods. the major agreements were: in Japanese adolescents BMI x NIR = 82.3% (cut-off point of 28%), BMI x BIA = 85.7% (cut-off point of 30%); in Caucasian adolescents BMI x NIR = 80.7% (cut-off point of 28%), BM I x BIA = 87.4% (cut-off point of 30%). the disagreement above the diagonal between BMI x NIR was higher within the two groups for both the cut-off points, revealing that the girls identified as obese by the BMI were considered eutrophic by NIR. in the 16- and 17-y-old adolescents, the BMI demonstrated low or no correlation with the other methods. Furthermore, it presented disagreements below the diagonal, revealing that the BMI identified fewer obese subjects than the other methods.CONCLUSION: Among the 10- and 11-y-olds, the BMI presented a good correlation with the other methods, independent of ethnicity. the BMI can therefore be used in place of these methods, although it may underestimate obesity. Among the 16- and 17-y-olds, the BMI presented low or no agreement with the other methods, suggesting that it is probably not a suitable index for this age-group in studies focusing on the identification of obesity. in such cases the choice of one of the other methods, depending on availability, cost or technical experience, may represent a better approach.
- ItemAcesso aberto (Open Access)Dermatoscopia na pele negra: estudo comparativo dos nevos melanocíticos adquiridos em pacientes com fototipos v e vi versus i e ii(Universidade Federal de São Paulo (UNIFESP), 2015-03-31) Tuma, Bruna [UNIFESP]; Hirata, Sergio Henrique [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)BLACKGROUND: The identification of "normal" dermoscopic pattern of acquired melanocytic nevi (AMN) provides a better diagnostic accuracy of melanoma in people with black skin. OBJECTIVE: Describe melanocytic lesions (number and anatomical distribution) in skin types V and VI (ST V/VI) compared to skin types I and II (ST I/II) according to Fitzpatrick's classification. Identify differences in dermoscopic findings of acquired melanocytic nevi (global pattern, pigment and color distribution) between the groups. METHODS: Cross-sectional, prospective and consecutive data collection in two dermatological outpatient clinic, between October 8, 2010, and March 20, 2013. From the 501 volunteers, 480 participants fullfilled the eligibility criteria. A total of 460 acquired melanocytic nevi were selected for dermoscopy analysis. RESULTS: The individuals with ST V/VI had less melanocytic lesions than those with ST I/II (15,08 vs 7,90, p=0,032), and the anatomical distribution in the first group was predominantly in the face and acral sites (p<0,001). The AMN in the group ST V/VI were associated with reticular pattern (p<0.0001), tendency to central hyperpigmentation (p=0.0025). LIMITATIONS: Choice of a single representative nevus per patient. CONCLUSION: The AMN in the individuals with ST V/VI has a distinct dermoscopic pattern from those with ST I/II.
- ItemAcesso aberto (Open Access)Dissecção espontânea das artérias carótidas e vertebrais em uma população multiétnica(Academia Brasileira de Neurologia - ABNEURO, 2007-12-01) Pieri, Alexandre [UNIFESP]; Spitz, Mariana [UNIFESP]; Valiente, Raul Alberto; Avelar, Wagner Mauad [UNIFESP]; Silva, Gisele Sampaio [UNIFESP]; Massaro, Ayrton Roberto [UNIFESP]; Universidade Federal de São Paulo (UNIFESP); Hospital Santa MarcelinaSpontaneous dissection of the carotid and vertebral arteries (SDCVA) is considered a rare cause of stroke, particularly in countries with multiethnic population. The objective was to evaluate the clinical and neuroimaging features of patients with SDCVA from a multiethnic population. Sixty-six patients diagnosed with SDCVA were studied at two tertiary hospitals at São Paulo. An initial questionnaire was completed and patients were followed prospectively. Among the patients studied, 82% were caucasian, 53% were male and the average age was 41.7 years old. The most frequent cardiovascular risk factors found were systemic hypertension and tobacco use. Other aspects evaluated were history of previous migraine, initial treatment and prognosis. In conclusion, although the population studied was multhiethnic, there was a marked predominance of caucasians. The analysis of clinical and neuroimaging data from patients with SDCVA allows a better understanding of the disease, leading to an earlier diagnosis and more appropriate treatment.
- ItemAcesso aberto (Open Access)Reconhecimento de padrão temporal e escuta dicótica em descendentes de japoneses, falantes e não-falantes da língua japonesa(ABORL-CCF Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-Facial, 2006-12-01) Onoda, Raquel Mari [UNIFESP]; Pereira, Liliane Desgualdo [UNIFESP]; Guilherme, Arnaldo [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)The aim of this study was to analyze the auditory behavior in Pitch(PPS) and Duration(DPS)Pattern Sequence tests and in the Dichotic Listening (Dichotic Digits Test/DDT) of familiar and unfamiliar words (Staggered Spondaic Words/SSW) in Japanese descendants that speak Japanese and Japanese descendants that do not speak Japanese, and to compare these findings with a group of non-Japanese descendants who have no contact with the Japanese language. METHOD: 60 High School graduates aged 17 to 40 years were evaluated. Subjects were divided into three groups: GJJ, Japanese descendants that speak Brazilian Portuguese and Japanese; GJP, Japanese descendants that speak Portuguese and do not speak Japanese; GBP non-oriental descendants that speak Brazilian Portuguese. All subjects filled in a questionnaire about their languages and musical abilities. Their ability in pattern-recognition tests was assessed by the PPS and DPS tests, their ability to recognize familiar words was tested by DDT and their ability to recognize unfamiliar words was tested by SSW. Results. GJJ and GJP showed higher performances than the group of Brazilians (GBP) in the PPS. RESULTS: show a statistically significant difference among the groups with a higher mean for the SSW results in GJJ compred to GJP and GBP. CONCLUSION:The results of SSW test seem to be influenced by bilingualism.
