Manumission of Slaves in Goa During 1682 to 1760 as found in Codex 860

The centre piece of my presentation is one particular and interesting manuscript of the Goa Historical Archives, listed as codex 860, which and contains details about manumission of slaves in Goa during the period 1682-1760. Curiously, the “Fathers of Christians” involved in this process of manumission were several Jesuits until the suppression of the Society of Jesus in 1759. The last four folios cover the year 1760 under a non-Jesuit, probably an Augustinian monk, appointed to take over the Old College of St Paul, while the Jesuits were detained before being deported.

Aleitamento no primeiro ano de vida de crianças internadas em hospital assistencial do município de São Paulo, Brasil

Estudo do tipo de aleitamento de 667 e 249 crianças internadas num hospital assistencial do município de São Paulo, Brasil, em 1969 e 1972, respectivamente, revelou uma queda do aleitamento natural exclusivo no primeiro ano de vida, de 5,85% em 1969 para 3,61% em 1972, e do aleitamento misto, de 5,55% para 4,42%. No primeiro semestre de vida, a queda no aleitamento natural exclusivo foi de 6,69% em 1969 para 4,81% em 1972, o mesmo se verificando no aleitamento misto. Em 1969, o aleitamento natural exclusivo caiu de 23,21% no primeiro mês para 4,06% no segundo mês, e em 1972, de 23,07% no primeiro mês para 3,33% no segundo mês. A freqüência do aleitamento artificial por leite em pó subiu de 81,11% em 1969 para 82,33% em 1972.

Deuterium NMR Study of Orientational Order in Cellulosic Network Microfibers

Deuterium NMR was used to investigate the orientational order in a composite cellulosic formed by liquid crystalline acetoxypropylcellulose (A PC) and demented nematic 4'-penty1-4-cyanobiphenyl (5CB-4 alpha d(2)) with the per centage of 85% A PC by weight Three forms of the composite including electro spun microfibers, thin film and bulk samples were analyzed The NMR results initially suggest two distinct scenarios, one whet e the 503-alpha d(2), is confined to small droplets with dimensions smaller than the magnetic coherence length and the other where the 503-alpha d(2) molecules arc aligned with the A PC network chains Polarized optical microscopy (POW from thin film samples along with all the NMR results show the presence of 5CB-alpha d(2) droplets in the composite systems with a nematic wetting layer at the APC-5CB-alpha d(2) interface that experiences and order disorder transition driven by the polymer network N-I transition The characterization of the APC network I-N transition shows a pronounced subcritical behavior within a heterogeneity scenario.

Caracterização microbiológica de águas utilizadas em hemodiálise

A insuficiência renal crónica tem como possível tratamento a hemodiálise de alto-fluxo de hemodiafiltração. Este estudo tem por objectivo caracterizar a qualidade de águas de diálise, provenientes de 4 clínicas. Realizou-se um estudo observacional descritivo transversal com base nos resultados das análises de águas de diálise, de 07-2009 a 04-2010. Nas amostras, à entrada do tratamento, verificou-se que 100% destas se encontravam nãoconformes nos parâmetros microbiológicos e 53,85% apresentavam-se não-conformes nos parâmetros químicos. Após tratamento, 6,41% continuavam não-conformes nos parâmetros microbiológicos e todas as amostras apresentaram-se conformes nos parâmetros químicos. Conclui-se que o tratamento tem elevado grau de efectividade.

In vitro transference and molecular characterization of bla TEM genes in bacteria isolated from Portuguese ready-to-eat foods

The principal aim of this study was to investigate the possibility of transference to Escherichia coli of β-lactam resistance genes found in bacteria isolated from ready-to-eat (RTE) Portuguese traditional food. From previous screenings, 128 β-lactam resistant isolates (from different types of cheese and of delicatessen meats), largely from the Enterobacteriaceae family were selected and 31.3% of them proved to transfer resistance determinants in transconjugation assays. Multiplex PCR in donor and transconjugant isolates did not detect bla CTX, bla SHV and bla OXY, but bla TEM was present in 85% of them, while two new TEMs (TEM-179 and TEM-180) were identified in two isolates. The sequencing of these amplicons showed identity between donor and transconjugant genes indicating in vitro plasmid DNA transfer. These results suggest that if there is an exchange of genes in natural conditions, the consumption of RTE foods, particularly with high levels of Enterobacteriaceae, can contribute to the spread of antibiotic resistance.

Re-evaluation of a reported increased micronucleus frequency in lymphocytes of workers occupationally exposed to formaldehyde

A replicate evaluation of increased micronucleus (MN) frequencies in peripheral lymphocytes of workers occupationally exposed to formaldehyde (FA) was undertaken to verify the observed effect and to determine scoring variability. May–Grünwald–Giemsa-stained slides were obtained from a previously performed cytokinesis-block micronucleus test (CBMNT) with 56 workers in anatomy and pathology laboratories and 85 controls. The first evaluation by one scorer (scorer 1) had led to a highly significant difference between workers and controls (3.96 vs 0.81 MN per 1000 cells). The slides were coded before re-evaluation and the code was broken after the complete re-evaluation of the study. A total of 1000 binucleated cells (BNC) were analysed per subject and the frequency of MN (in ‰) was determined. Slides were distributed equally and randomly between two scorers, so that the scorers had no knowledge of the exposure status. Scorer 2 (32 exposed, 36 controls) measured increased MN frequencies in exposed workers (9.88 vs 6.81). Statistical analysis with the two-sample Wilcoxon test indicated that this difference was not significant (p = 0.17). Scorer 3 (20 exposed, 46 controls) obtained a similar result, but slightly higher values for the comparison of exposed and controls (19.0 vs 12.89; p = 0.089). Combining the results of the two scorers (13.38 vs 10.22), a significant difference between exposed and controls (p = 0.028) was obtained when the stratified Wilcoxon test with the scorers as strata was applied. Interestingly, the re-evaluation of the slides led to clearly higher MN frequencies for exposed and controls compared with the first evaluation. Bland–Altman plots indicated that the agreement between the measurements of the different scorers was very poor, as shown by mean differences of 5.9 between scorer 1 and scorer 2 and 13.0 between scorer 1 and scorer 3. Calculation of the intra-class correlation coefficient (ICC) revealed that all scorer comparisons in this study were far from acceptable for the reliability of this assay. Possible implications for the use of the CBMNT in human biomonitoring studies are discussed.

Sentimento de discriminação em estudantes: prevalência e fatores associados

OBJETIVO: Estimar a prevalência e fatores associados ao sentimento de discriminação entre estudantes. MÉTODOS: Estudo transversal com amostra representativa de 1.170 escolares de um total de 2.282 matriculados na sétima série do ensino fundamental em escolas municipais de Gravataí (RS), em 2005. Os participantes foram selecionados por amostragem aleatória por conglomerado. Os dados foram obtidos com instrumentos auto-aplicados (Global School-based Student Health Survey, body shape questionnaire, classificação socioeconômica) preenchidos em sala de aula. Foi utilizada a regressão de Cox modificada para estudos transversais, segundo modelo hierarquizado em quatro etapas. RESULTADOS: A prevalência de sentimento de discriminação foi de 21,0%, mais prevalente entre: as meninas (RP=1,93, IC 95% 1,51;2,46); os que apresentaram absenteísmo escolar (RP=1,54, IC 95% 1,21;1,97); os que fizeram uso na vida de tabaco (RP=1,53, IC 95% 1,18;1,98); os preocupados com sua imagem corporal (RP=1,42, IC 95% 1,07;1,88); os com sentimento de solidão (RP=2,50, IC 95% 1,80;3,46) e tristeza (RP=1,29, IC 95% 1,02;1,62); os com dificuldade para dormir (RP:1,41, IC 95% 1,08;1,83); os com ideação suicida (RP=1,45, IC 95% 1,13;1,85) e os que sofreram algum tipo de injúria acidental (RP=1,56, IC 95% 1,23;1,97) ou intencional (RP=2,04, IC 95% 1,51;2,76). CONCLUSÕES: O sentimento de discriminação esteve associado ao sexo e à experiência com tabaco. Sua associação com fatores psicossociais indica a coexistência de situações adversas, como a insatisfação com a imagem corporal, sintomas depressivos e presença de injúrias. Esses resultados mostram a importância da atuação conjunta de professores e profissionais de saúde na identificação precoce desse sentimento, orientação e acompanhamento de jovens enfrentando essas situações.

Risk factors for osteoporotic fractures and low bone density in pre and postmenopausal women

OBJECTIVE: To estimate the prevalence and analyze risk factors associated to osteoporosis and low-trauma fracture in women. METHODS: Cross-sectional study including a total of 4,332 women older than 40 attending primary care services in the Greater São Paulo, Southeastern Brazil, between 2004 and 2007. Anthropometrical and gynecological data and information about lifestyle habits, previous fracture, medical history, food intake and physical activity were obtained through individual quantitative interviews. Low-trauma fracture was defined as that resulting from a fall from standing height or less in individuals 50 years or older. Multiple logistic regression models were designed having osteoporotic fracture and bone mineral density (BMD) as the dependent variables and all other parameters as the independent ones. The significance level was set at p<0.05. RESULTS: The prevalence of osteoporosis and osteoporotic fractures was 33% and 11.5%, respectively. The main risk factors associated with low bone mass were age (OR=1.07; 95% CI: 1.06;1.08), time since menopause (OR=2.16; 95% CI: 1.49;3.14), previous fracture (OR=2.62; 95% CI: 2.08;3.29) and current smoking (OR=1.45; 95% CI: 1.13;1.85). BMI (OR=0.88; 95% CI: 0.86;0.89), regular physical activity (OR=0.78; 95% CI: 0.65;0.94) and hormone replacement therapy (OR=0.43; 95% CI: 0.33;0.56) had a protective effect on bone mass. Risk factors significantly associated with osteoporotic fractures were age (OR=1.05; 95% CI: 1.04;1.06), time since menopause (OR=4.12; 95% CI: 1.79;9.48), familial history of hip fracture (OR=3.59; 95% CI: 2.88;4.47) and low BMD (OR=2.28; 95% CI: 1.85;2.82). CONCLUSIONS: Advanced age, menopause, low-trauma fracture and current smoking are major risk factors associated with low BMD and osteoporotic fracture. The clinical use of these parameters to identify women at higher risk for fractures might be a reasonable strategy to improve the management of osteoporosis.

The value of adenosine deaminase (ADA) determination in the diagnosis of tuberculous ascites

In order to evaluate the role of the determination of adenosine deaminase activity (ADA) in ascitic fluid for the diagnosis of tuberculosis, 44 patients were studied. Based on biochemical, cytological, histopathological and microbiological tests, the patients were divided into 5 groups: G1 - tuberculous ascites (n = 8); G2 - malignant ascites (n = 13); G3 - spontaneous bacterial peritonitis (n = 6); G4 - pancreatic ascites (n = 2); G5 - miscelaneous ascites (n = 15). ADA concentration were significantly higher in G1 (133.50 ± 24.74 U/l) compared to the other groups (G2 = 41.85 ± 52.07 U/l; G3 = 10.63 ± 5.87 U/l; G4 = 18.00 ± 7.07 U/l; G5 = 11.23 ± 7.66 U/l). At a cut-off value of >31 U/l, the sensitivity, specificity and positive and negative preditive values were 100%, 92%, 72% and 100%, respectively. ADA concentrations as high as in tuberculous ascites were only found in two malignant ascites caused by lymphoma. We conclude that ADA determination in ascitic fluid is a useful and reliable screening test for diagnosing tuberculous ascites. Values of ADA higher than 31 U/l indicate more invasive methods to confirm the diagnosis of tuberculosis.

HANTAVIRUS PULMONARY SYNDROME IN THE PROVINCE OF RIO NEGRO, ARGENTINA, 1993-1996

Early in 1995 the first case of Hantavirus Pulmonary Syndrome was serologically confirmed in El Bolsón (Province of Río Negro, Argentina), corresponding to the third outbreak reported in Argentina. A total of 26 cases of HPS related to the Andean region of Rio Negro Province, were reported from 1993 to 1996, 17 in El Bolsón, 4 in San Carlos de Bariloche, and 5 in Buenos Aires. The incidence rate was 5.03 x 100000 with a mortality rate of 51.85 x 100. The occurrence of cases was mainly seasonal, with a significantly greater number in the spring, and the persons affected mainly lived in urban or periurban areas. In four cases, the affected individuals were members of a couple, spouses or live-in contacts. Seven cases were Health workers (physicians, nurses or administrative staff). Twelve cases were related among them, due to an outbreak of 80 days. Two of them did not visit the Andean region. A total of 139 rodents were captured and seven of them, Olygoryzomys longicaudatus, were found to be serologically positive. The possibility of infection by contact with rodents or fecal matter is being analyzed and also hypothesis related with interhuman transmission
