Objective: To evaluate the benefits of coordinating community services through the Post-Acute Care (PAC) program in older patients after discharge from hospital. Design: Prospective multicentre, randomised controlled trial with six months of follow-up with blinded outcome measurement. Setting: Four university-affiliated metropolitan general hospitals in Victoria. Participants: All patients aged 65 years and over who were discharged between August 1998 and October 1999 and required community services after discharge. Interventions: Participants were randomly allocated to receive services of a Post-Acute Care (PAC) coordinator (intervention) versus usual discharge planning (control). Main outcome measures: Comparison of quality of life and carer stress at one-month post-discharge, mortality, hospital readmissions, use of community services and community and hospital costs over the six months post-discharge. Results: 654 patients were randomised, and 598 were included in the analysis (311 in the PAC group and 287 in the control group). There was no difference in mortality between the groups (both 6%), but significantly greater overall quality-of-life scores at one-month follow-up in the PAC group. There was no difference in unplanned readmissions, but PAC patients used significantly fewer hospital bed-days in the six months after discharge (mean, 3.0 days; 95% CI, 2.1-3.9) than control patients (5.2 days; 95% CI, 3.8-6.7). Total costs (including hospitalisation, community services and the intervention) were lower in the PAC than the control group (mean difference, $1545; 95% CI, $11-$3078). Conclusions: The PAC program is beneficial in the transition from hospital to the community in older patients.

Cytokines are important for breast cell function, both as trophic hormones and as mediators of host defense mechanisms against breast cancer. Recently, inducible feedback suppressors of cytokine signalling (SOCS/JAB/SSI) have been identified, which decrease cell sensitivity to cytokines. We examined the expression of SOCS genes in 17 breast carcinomas and 10 breast cancer lines, in comparison with normal tissue and breast lines. We report elevated expression of SOCS-1-3 and CIS immunoreactive proteins within in situ ductal carcinomas and infiltrating ductal carcinomas relative to normal breast tissue. Significantly increased expression of SOCS-1-3 and CIS transcripts was also shown by quantitative in situ hybridisation within both tumour tissue and reactive stroma. CIS transcript expression was elevated in all 10 cancer lines, but not in control lines. However, there was no consistent elevation of other SOCS transcripts. CIS protein was shown by immunoblot to be present in all cancer lines at increased levels, mainly as the 47 kDa ubiquitinylated form. A potential proliferative role for CIS overexpression is supported by reports that CIS activates ERK kinases, and by strong induction in transient reporter assays with an ERK-responsive promoter. The in vivo elevation of SOCS gene expression may be part of the host/tumour response or a response to autocrine/paracrine GH and prolactin. However, increased CIS expression in breast cancer lines appears to be a specific lesion, and could simultaneously shut down STAT 5 signalling by trophic hormones, confer resistance to host cytokines and increase proliferation through ERK kinases.

A ocorrência de corpos estranhos em otorrinolaringologia é motivo de freqüentes consultas em serviços de emergência. OBJETIVO: Avaliar a incidência de pacientes com corpo estranho, bem como analisar o quadro clínico e o tratamento nestes casos. MÉTODO: Foi realizado estudo prospectivo de 81 pacientes com diagnóstico de corpo estranho de nariz, orelha ou orofaringe admitidos no Serviço de Otorrinolaringologia do Hospital do Servidor Público Municipal de São Paulo, no período de abril de 2003 a março de 2005. RESULTADOS: Foram 57 casos de corpo estranho de orelha; 13 de cavidade nasal; e 11 de orofaringe. Destes pacientes, 51,85% foram do sexo masculino e 48,15% do sexo feminino. A média de idade foi de 23 anos. A média do tempo de evolução foi de 18,36 dias, sendo que 38,27% dos casos foram atendidos com menos de 24 horas de evolução. Do total de pacientes, 83,95% receberam atendimento inicial na clínica de otorrinolaringologia, e 16,05% vieram encaminhados de outro serviço após alguma tentativa de remoção prévia. O sintoma mais comum dos casos de corpos estranhos de orofaringe foi a odinofagia presente em 90,91% dos casos; nos corpos estranhos de nariz, a rinorréia unilateral e cacosmia estiveram presentes em 46,15% dos casos; e nos corpos estranhos de orelha, 38,60% evoluíram sem sintomas, e 28,07% com hipoacusia. O corpo estranho mais freqüente de orofaringe foi a espinha de peixe (54,55%); no nariz foi o papel (30,77%); e na orelha foi o algodão (31,58%). As complicações decorrentes da presença de corpo estranho ou da manipulação dos mesmos foram encontradas em 13 casos (16,05%). CONCLUSÃO: A maioria dos casos com manipulação prévia para remoção de corpo estranho por profissional não-habilitado ou por leigo evoluiu com complicações, enfatizando que o manejo dos pacientes com corpo estranho deve ser realizado pelo médico otorrinolaringologista e com o uso de material adequado.

At the close of the Wars of the Roses, a new dynasty was founded by a man lacking a prince’s education; moreover, his weak claim to the throne of England gave rise to a set of serious problems. These two crucial, interrelated elements are central in Francis Bacon’s biographical account of Henry VII. The literal road leading Richmond from exile to victory in Bosworth Field, in 1485, is eventually transformed into a metaphoric path that prefigures the long, deep process of learning undertaken during his 24-year reign. This fundamental process carried out by the king will be approached mainly through the passages focused on the Lambert Simnell/Perkin Warbeck affairs, the most difficult probelms the monarch had to face in a time and in a kingdom of many uncertainties. The Simnell/Warbeck menaces embodied Henry Tudor’s greatest dilemmas, continually emphasised in Bacon’s work – the essence of legitimacy and the essence of royalty.

We investigate a mechanism that generates exact solutions of scalar field cosmologies in a unified way. The procedure investigated here permits to recover almost all known solutions, and allows one to derive new solutions as well. In particular, we derive and discuss one novel solution defined in terms of the Lambert function. The solutions are organised in a classification which depends on the choice of a generating function which we have denoted by x(phi) that reflects the underlying thermodynamics of the model. We also analyse and discuss the existence of form-invariance dualities between solutions. A general way of defining the latter in an appropriate fashion for scalar fields is put forward.

OBJETIVO: Elaborar indicadores de desempenho e terceirização em rede de laboratórios clínicos, baseados em sistemas de informações e registros administrativos públicos. MÉTODOS: A rede tinha 33 laboratórios com equipamentos automatizados, mas sem informatização, 90 postos de coleta e 983 funcionários, no município de Rio de Janeiro, RJ. As informações foram obtidas de registros administrativos do Sistema de Informações de Orçamentos Públicos para a Saúde e do Sistema de Informações Ambulatoriais e Hospitalares do Sistema Único de Saúde. Os indicadores (produção, produtividade, utilização e custos) foram elaborados com dados colhidos como rotina de 2006 a 2008. As variações da produção, custos e preços unitários dos testes no período foram analisadas por índices de Laspeyres e de Paasche, específicos para medir a atividade dos laboratórios, e pelo Índice de Preços ao Consumidor Amplo do Instituto Brasileiro de Geografia e Estatística. RESULTADOS: A produção foi de 10.359.111 testes em 2008 (aumento de 10,6% em relação a 2006) e a relação testes/funcionário cresceu 8,6%. As despesas com insumos, salários e prestador conveniado aumentaram, respectivamente 2,3%, 45,4% e 18,3%. Os testes laboratoriais por consulta e internação cresceram 10% e 20%. Os custos diretos totalizaram R$ 63,2 milhões em 2008, com aumento de 22,2% em valores correntes no período. Os custos diretos deflacionados pelo Índice de Preços ao Consumidor Amplo (9,5% para o período) mostram aumento do volume da produção de 11,6%. O índice de volume específico para a atividade, que considera as variações do mix de testes, mostrou aumento de 18,5% no preço unitário do teste e de 3,1% no volume da produção. CONCLUSÕES: Os indicadores, em especial os índices específicos de volume e preços da atividade, constituem uma linha de base de desempenho potencial para acompanhar laboratórios próprios e terceirizados. Os indicadores de desempenho econômicos elaborados mostram a necessidade de informatização da rede, antecedendo a decisão de terceirização.

OBJECTIVE To evaluate the cross-cultural validity of the Demand-Control Questionnaire, comparing the original Swedish questionnaire with the Brazilian version. METHODS We compared data from 362 Swedish and 399 Brazilian health workers. Confirmatory and exploratory factor analyses were performed to test structural validity, using the robust weighted least squares mean and variance-adjusted (WLSMV) estimator. Construct validity, using hypotheses testing, was evaluated through the inspection of the mean score distribution of the scale dimensions according to sociodemographic and social support at work variables. RESULTS The confirmatory and exploratory factor analyses supported the instrument in three dimensions (for Swedish and Brazilians): psychological demands, skill discretion and decision authority. The best-fit model was achieved by including an error correlation between work fast and work intensely (psychological demands) and removing the item repetitive work (skill discretion). Hypotheses testing showed that workers with university degree had higher scores on skill discretion and decision authority and those with high levels of Social Support at Work had lower scores on psychological demands and higher scores on decision authority. CONCLUSIONS The results supported the equivalent dimensional structures across the two culturally different work contexts. Skill discretion and decision authority formed two distinct dimensions and the item repetitive work should be removed.

The methods of molecular biology applied in epidemiological research lead us to the realm of molecular epidemiology, where there is immense potential for the establishment of associations between cancer and exposure to risk factors in lifestyle, profession, or pollution. Human biomonitoring consists, on the one hand, in research and identification of hazardous environmental conditions and, on the other hand, in the assessment of cancer risk following exposure to such conditions. Since carcinogenesis is a lengthy process, the biomarkers used to recognize biological abnormalities are selected and developed in the realm of molecular epidemiology. Such biomarkers are quantifiable and allow for the recognition of progression from normal to abnormal biological conditions at the molecular level. They can be categorized in biomarkers of exposure, effect, and genetic susceptibility. Genotoxicity biomarkers are a particular subset of effect biomarkers and are used to assess genomic instability caused by environmental or occupational exposure, being considered useful carcinogenesis predictors.

The aim of this case series was to describe the clinical, laboratory and epidemiological characteristics and the presentation of bacillary angiomatosis cases (and/or parenchymal bacillary peliosis) that were identified in five public hospitals of Rio de Janeiro state between 1990 and 1997; these cases were compared with those previously described in the medical literature. Thirteen case-patients were enrolled in the study; the median age was 39 years and all patients were male. All patients were human immunodeficiency virus type 1 (HIV-1) infected and they had previous or concomitant HIV-associated opportunistic infections or malignancies diagnosed at the time bacillary angiomatosis was diagnosed. Median T4 helper lymphocyte counts of patients was 96 cells per mm³. Cutaneous involvement was the most common clinical manifestation of bacillary angiomatosis in this study. Clinical remission following appropriate treatment was more common in our case series than that reported in the medical literature, while the incidence of relapse was similar. The frequency of bacillary angiomatosis in HIV patients calculated from two of the hospitals included in our study was 1.42 cases per 1000 patients, similar to the frequencies reported in the medical literature. Bacillary angiomatosis is an unusual opportunistic pathogen in our setting.

Eight new peptides were isolated from the skin secretion of the frog Leptodactylus pustulatus and their amino acid sequences determined by de novo sequencing and by cDNA cloning. Structural similarities between them and other antimicrobial peptides from the skin secretion of Leptodactylus genus frogs were found. Ocellatins-PT1 to -PT5 (25 amino acid residues) are amidated at the C-terminus, while ocellatins-PT6 to -PT8 (32 amino acid residues) have free carboxylates. Antimicrobial activity, hemolytic tests, and cytotoxicity against a murine fibroblast cell line were investigated. All peptides, except for ocellatin-PT2, have antimicrobial activity against at least one Gram negative strain. Ocellatin-PT8 inhibited the growth of Escherichia coli, Staphylococcus aureus, Klebsiella pneumoniae, and Salmonella choleraesuis strains with MICs in the 60−240 μM range. No significant effect was observed in human erythrocytes and in a murine fibroblast cell line after exposure to the peptides at MICs. A comparison between sequences obtained by both direct HPLC-MS de novo sequencing and cDNA cloning demonstrates the secretion of mature peptides derived from a pre-pro-peptide structure.
