Políticas e gestão da comunicação no Brasil contemporâneo

O volume, organizado pelo professor Danilo Rothberg, reúne artigos de docentes e pesquisadores de pós-graduação das áreas de ciências humanas e sociais que buscam esclarecer ações que envolvem a comunicação desenvolvida por atores sociais a fim de ampliar os espaços democráticos. A maior parte dos artigos são de autoria de docentes da Unesp e tratam de temas relacionados à comunicação via Internet e de sua aplicação em iniciativas políticas e de interação de instâncias de poder com o público. Mas o livro ainda discute outros meios, como rádio e televisão, além da comunicação organizacional. A obra procura aplicar o conhecimento científico no campo da comunicação desenvolvido nas universidades à realidade do Brasil de hoje. Diante do quadro de constante inovação das formas de se comunicar observado nos últimos anos, os autores contribuem para superar um cenário de aparente falta de informações sobre as realizações políticas e de gestão do setor.

Health related quality of life measure in systemic pediatric rheumatic diseases and its translation to different languages: an international collaboration

Background: Rheumatic diseases in children are associated with significant morbidity and poor health-related quality of life (HRQOL). There is no health-related quality of life (HRQOL) scale available specifically for children with less common rheumatic diseases. These diseases share several features with systemic lupus erythematosus (SLE) such as their chronic episodic nature, multi-systemic involvement, and the need for immunosuppressive medications. HRQOL scale developed for pediatric SLE will likely be applicable to children with systemic inflammatory diseases.Findings: We adapted Simple Measure of Impact of Lupus Erythematosus in Youngsters (SMILEY (c)) to Simple Measure of Impact of Illness in Youngsters (SMILY (c)-Illness) and had it reviewed by pediatric rheumatologists for its appropriateness and cultural suitability. We tested SMILY (c)-Illness in patients with inflammatory rheumatic diseases and then translated it into 28 languages. Nineteen children (79% female, n= 15) and 17 parents participated. The mean age was 12 +/- 4 years, with median disease duration of 21 months (1-172 months). We translated SMILY (c)-Illness into the following 28 languages: Danish, Dutch, French (France), English (UK), German (Germany), German (Austria), German (Switzerland), Hebrew, Italian, Portuguese (Brazil), Slovene, Spanish (USA and Puerto Rico), Spanish (Spain), Spanish (Argentina), Spanish (Mexico), Spanish (Venezuela), Turkish, Afrikaans, Arabic (Saudi Arabia), Arabic (Egypt), Czech, Greek, Hindi, Hungarian, Japanese, Romanian, Serbian and Xhosa.Conclusion: SMILY (c)-Illness is a brief, easy to administer and score HRQOL scale for children with systemic rheumatic diseases. It is suitable for use across different age groups and literacy levels. SMILY (c)-Illness with its available translations may be used as useful adjuncts to clinical practice and research.

Cumulative long-term safety, efficacy and patient-reported outcomes in children with juvenile idiopathic arthritis treated with intravenous abatacept: up to 7 years of treatment

The long-term efficacy and safety of intravenous abatacept in patients (pts) with juvenile idiopathic arthritis (JIA) have been reported previously from the Phase III AWAKEN trial ([1, 2]). Here, we report efficacy, safety and pt-reported outcomes from the open-label, long-term extension (LTE) of AWAKEN, with up to 7 years of follow-up. Pts entered the LTE if they were JIA ACR 30 non-responders (NR) at the end of the 4-month lead-in period (abatacept only), or if they received abatacept or placebo (pbo) in the 6-month double-blind (DB) period. The Child Health Questionnaire was used to evaluate health-related quality of life (HRQoL); physical (PhS) and psychosocial (PsS) summary and pain scores were analyzed. Pain was assessed by parent global assessment using a 100 mm visual analog scale. Efficacy and HRQoL evaluations are reported up to Day 1765 (~ Year 5.5). Safety is presented for the cumulative period (lead-in, DB and LTE), for all pts who received abatacept during the LTE. Of the 153 pts entering the LTE (58 from DB abatacept group, 59 from DB pbo group, 36 NR), 69 completed the trial (29 abatacept, 27 pbo, 13 NR). For pts treated in the LTE, mean (range) exposure to abatacept was 53.6 (5.6–85.6) months. During the LTE, incidence rates of AEs and serious AEs per 100 pt-years were 209.1 and 5.6. Thirty pts (19.6%) had serious AEs; most were unrelated and were musculoskeletal (8.5%) or infectious events (6.5%). No malignancy was reported. There was one death (accidental; unrelated). At Day 169, JIA ACR 50 and 70 response rates were 79.3% and 55.2% in the abatacept group, and 52.5% and 30.5% in the pbo group; 31.0% and 10.2% of pts in the abatacept and pbo groups, respectively, had inactive disease. By Day 1765, JIA ACR 50 and 70 response rates were 93.9% and 78.8% in the abatacept group, and 80.0% and 63.3% in the pbo group; 51.5% and 33.3% had inactive disease. In the NR group, 69.2% and 53.8% of pts achieved JIA ACR 50 and 70 responses at Day 1765, and 30.8% had inactive disease. In pts who entered the LTE, mean baseline PhS scores were below the range for healthy children (abatacept 30.2, pbo 31.0, NR 29.5). At Day 169, 38.3% of pts had reached a PhS score >50 ((1). By the end of the LTE, 43.5% of pts had reached a PhS score >50. At baseline, mean PsS scores for those who entered the LTE were slightly lower than the mean for healthy children (abatacept 43.5, pbo 44.2, NR 47.0). At Day 169, 54.9% of pts had a PsS score >50 (1). By Day 1765, 58.1% of pts had reached a PsS score >50. At baseline, the mean pain score was 42.9. By Day 169, 13.9% of pts were considered pain free (pain score = 0); this was maintained over the LTE (1).

Abordagem biocomportamental: síntese da análise do comportamento?

O artigo comenta as linhas gerais da abordagem biocomportamental a partir de dois trabalhos (Donahoe, Burgos, & Palmer, 1993; Donahoe & Palmer, 1994). A hipótese apresentada é a de que uma teoria sintética das origens do comportamento complexo mostraria como os efeitos cumulativos de processos de reforçamento relativamente simples levam à diversidade e complexidade do comportamento humano. Esses autores partem da simulação computacional para gerar analogias do fenômeno comportamental complexo, integrando processos neurológicos que tenham sido estabelecidos através de análise experimental. A integração de achados comportamentais e neurocientíficos constituiria uma síntese que poderia reivindicar a complexidade comportamental como seu domínio.

HYDRODYNAMICS AND SUSPENDED SEDIMENT TRANSPORT IN THE CAMBORIU ESTUARY - BRAZIL: PRE JETTY CONDITIONS

Estuarine hydrodynamics is a key factor in the definition of the filtering capacity of an estuary and results from the interaction of the processes that control the inlet morphodynamics and those that are acting in the mixing of the water in the estuary. The hydrodynamics and suspended sediment transport in the Cambori estuary were assessed by two field campaigns conducted in 1998 that covered both neap and spring tide conditions. The period measured represents the estuarine hydrodynamics and sediment transport prior to the construction of the jetty in 2003 and provides important background information for the Cambori estuary. Each field campaign covered two complete tidal cycles with hourly measurements of currents, salinity, suspended sediment concentration and water level. Results show that the Cambori estuary is partially mixed with the vertical structure varying as a function of the tidal range and tidal phase. The dynamic estuarine structure can be balanced between the stabilizing effects generated by the vertical density gradient, which produces buoyancy and stratification flows, and the turbulent effects generated by the vertical velocity gradient that generates vertical mixing. The main sediment source for the water column are the bottom sediments, periodically resuspended by the tidal currents. The advective salt and suspended sediment transport was different between neap and spring tides, being more complex at spring tide. The river discharge term was important under both tidal conditions. The tidal correlation term was also important, being dominant in the suspended sediment transport during the spring tide. The gravitational circulation and Stokes drift played a secondary role in the estuarine transport processes.

Determination of flagellar types by PCR-RFLP analysis of enteropathogenic Escherichia coli (EPEC) and Shiga toxin-producing E. coli (STEC) strains isolated from animals in Sao Paulo, Brazil

This study evaluated the polymerase chain reaction- restriction fragment length polymorphism (PCR-RFLP) analysis of fliC for typing flagella antigen (H) of Shiga toxin-producing Escherichia coil (STEC) and enteropathogenic E. coli (EPEC) strains isolated from different animals. The molecular typing of the H type was efficient in the determination of 93 (85%) strains. Two nonmotile (H-) E. coil strains showed a PCR-RFLP electrophoretic profile that did not match known H type patterns. The fliC nucleotide sequence of strains B2N and 4a revealed a nucleotide substitution at the restriction site and a nucleotide insertion that generated a stop codon, respectively. The results of this study showed that PCR-RFLP analysis of fliC is faster, less laborious and as efficient for the determination of H type E. coli isolated from animals, compared to serotyping and that it is useful in determining H type in nonmotile strains and strains expressing non-reactive H antigens. Moreover, the fliC sequence of strain B2N suggests that we could have found a new flagellin antigen type. (C) 2010 Elsevier Ltd. All rights reserved.

Comparison of the Clinical Expression of Patients with Ankylosing Spondylitis from Europe and Latin America

Objective. To compare the clinical, demographic, and serologic characteristics and the treatment of patients diagnosed with ankylosing spondylitis (AS) from Europe (EU) and Latin America (LA). Methods. We included 3439 patients from national registries: the Spanish Registry of Spondyloarthritis (REGISPONSER), the Belgian registry (ASPECT), and the Latin American Registry of Spondyloarthropathies (RESPONDIA). We selected patients with diagnosis of AS who met the modified New York classification criteria. Demographic, clinical, disease activity, functional, and metrological measurement data were recorded. Current treatment was recorded. The population was classified into 2 groups: patients with disease duration < 10 years and those with disease duration >= 10 years. A descriptive and comparative analysis of variables of both groups was carried out. Results. There were 2356 patients in EU group and 1083 in LA group. Prevalence of HLA-B27 was 71% in LA group and 83% in EU group (p < 0.001). We found a greater frequency of peripheral arthritis and enthesitis (p < 0.001) in the LA population; prevalence of arthritis was 57% in LA and 42% in EU, and for enthesitis, 54% and 38%. Except for treatment with anti-tumor necrosis factor (anti-TNF), the use of nonsteroidal antiinflammatory drugs (NSAID), corticosteroids, and disease-modifying antirheumatic drugs (DMARD), and the association of anti-TNF and methotrexate use showed a significant difference (p < 0.001) in the 2 populations. Conclusion. The principal differences in the clinical manifestations of patients with AS from EU and LA were the greater frequency of peripheral arthritis and enthesitis in LA group, the higher percentage of HLA-B27 in EU group, and the form of treatment, with a greater use of NSAID, steroids, and DMARD in the LA group.

Adipose Tissue-Derived Stem Cell Treatment Prevents Renal Disease Progression

Adipose tissue-derived stem cells (ASCs) are an attractive source of stem cells with regenerative properties that are similar to those of bone marrow stem cells. Here, we analyze the role of ASCs in reducing the progression of kidney fibrosis. Progressive renal fibrosis was achieved by unilateral clamping of the renal pedicle in mice for 1 h; after that, the kidney was reperfused immediately. Four hours after the surgery, 2 x 10(5) ASCs were intraperitoneally administered, and mice were followed for 24 h posttreatment and then at some other time interval for the next 6 weeks. Also, animals were treated with 2 x 10(5) ASCs at 6 weeks after reperfusion and sacrificed 4 weeks later to study their effect when interstitial fibrosis is already present. At 24 h after reperfusion, ASC-treated animals showed reduced renal dysfunction and enhanced regenerative tubular processes. Renal mRNA expression of IL-6 and TNF was decreased in ASC-treated animals, whereas IL-4. IL-10, and HO-1 expression increased despite a lack of ASCs in the kidneys as determined by SRY analysis. As expected, untreated kidneys shrank at 6 weeks, whereas the kidneys of ASC-treated animals remained normal in size, showed less collagen deposition, and decreased staining for FSP-1, type I collagen, and Hypoxyprobe. The renal protection seen in ASC-treated animals was followed by reduced serum levels of TNF-alpha, KC, RANTES, and IL-1 alpha. Surprisingly, treatment with ASCs at 6 weeks, when animals already showed installed fibrosis, demonstrated amelioration of functional parameters, with less tissue fibrosis observed and reduced mRNA expression of type I collagen and vimentin. ASC therapy can improve functional parameters and reduce progression of renal fibrosis at early and later times after injury, mostly due to early modulation of the inflammatory response and to less hypoxia, thereby reducing the epithelial-mesenchymal transition.

Relationships between gender, age, family conditions, physical and mental health, and social isolation of elderly caregivers

Background: In an aging population an increasing number of elderly caregivers will be called upon to provide care over a long period, during which time they will be burdened both by caregiving and by the physiological effects of their own aging. Among them there will be more aged male caregivers, who will probably be less prepared than women to become caregivers. The aim of this study was to investigate the relationship between caregivers' gender, age, family income, living arrangements and social support as independent variables, and depressive symptoms, comorbidities, level of frailty, grip strength, walking speed and social isolation, as dependent variables. Methods: 176 elderly people (123 women) were selected from a sample of a population-based study on frailty (n = 900), who had cared for a spouse (79.3%) and/or parents (31.4%) in the past five years (mean age = 71.8 +/- 4.86 years; mean monthly family income in minimum wages = 4.64 +/- 5.14). The study used questionnaires and self-report scales, grip strength and walking speed tests. Results: 65% of participants evaluated caregiving as being very stressful. Univariate analyses of regression showed low family income as a risk factor for depression; being female and low perceived social support as a risk for comorbidities; being 80 years of age and above for low grip strength; and being male for social isolation indicated by discontinuity of activities and social roles. In multivariate analyses of regression, poverty arose as a risk factor for depression and being female for comorbidities. Conclusions: Gender roles, age, income and social support interacted with physical and emotional health, and with the continuity of social participation of elderly caregivers. Special attention must be given to male caregivers.
