Inclusão escolar pela via da colaboração entre educação especial e educação regular

A preocupação sobre as práticas inclusivas nas escolas públicas no Brasil começou após a Declaração de Salamanca, com desafios e dúvidas. Ainda hoje, passados cerca de 15 anos, os professores do ensino regular se queixam dizendo que não têm conhecimento suficiente ou preparo formal para lidar com crianças com necessidades educacionais especiais, especialmente quando estas apresentam disfunções graves, como paralisia cerebral, deficiência intelectual e comportamentos desafiadores. A colaboração entre profissionais da Educação Especial e Regular pode ser uma alternativa para enfrentar tais desafios. O objetivo deste relato foi o de apresentar um breve histórico de um programa de pesquisa, ensino e extensão que busca aproximar a Universidade Federal de São Carlos (UFSCar) dos professores do ensino comum que têm alunos com necessidades especiais em suas salas de aula. Iniciado em 2004, este programa está na atualidade em seu sétimo ano de execução e envolve professores da universidade, estudantes de graduação e pós-graduação e professores do ensino comum. Os resultados parecem apontar essa via de colaboração entre Educação Especial e Regular como um caminho promissor para a construção de escolas mais inclusivas.

Avaliação da estrutura organizacional da assistência ambulatorial em HIV/Aids no Brasil

OBJETIVO: No contexto de acesso universal à terapia antiretroviral, os resultados do Programa de Aids dependem da qualidade do cuidado prestado. O objetivo do estudo foi avaliar a qualidade do cuidado dos serviços ambulatoriais que assistem pacientes de Aids. MÉTODOS: Estudo realizado em sete Estados brasileiros, em 2001 e 2002. Foi avaliada a qualidade do atendimento a pacientes com Aids quanto à disponibilidade de recursos e a organização do trabalho de assistência. Um questionário com 112 questões estruturadas abordando esses aspectos, foi enviado a 336 serviços. RESULTADOS: A taxa de resposta foi de 95,8% (322). Os indicadores de disponibilidade de recursos mostram uma adequação maior do que os indicadores de organização do trabalho. Não faltam antiretrovirais em 95,5% dos serviços, os exames de CD4 e Carga Viral estão disponíveis em quantidade adequada em 59 e 41% dos serviços, respectivamente. em 90,4% dos serviços há pelo menos um profissional não médico (psicólogo, enfermeiro ou assistente social). Quanto à organização, 80% não agendavam consulta médica com hora marcada; 40,4% agendavam mais que 10 consultas médicas por período; 17% não possuíam gerentes exclusivos na assistência e 68,6% não realizavam reuniões sistemáticas de trabalho com a equipe. CONCLUSÕES: Os resultados apontam que além de garantir a distribuição mais homogênea de recursos, o programa precisa investir no treinamento e disseminação do manejo do cuidado, conforme evidenciado nos resultados da organização de trabalho.

Aspectos radiográficos e densitométricos na consolidação de fraturas tratadas por proteínas morfogenéticas ósseas em rádio de coelhos

Avaliou-se, por meio de exames radiográficos e densitométricos, a influência de um biomaterial desenvolvido pela indústria brasileira, no processo de reparação de fraturas diafisárias instáveis do rádio. Foram utilizados 15 coelhos Norfolk, machos, idade entre cinco e seis meses e peso corpóreo médio de 3,5kg. Induziu-se fratura transversa na porção média da diáfise de ambos os rádios direito, por meio de serra giratória. Ao redor das extremidades fraturadas do rádio direito (tratado) aplicou-se BMPs adsorvidas à hidroxiapatita e aglutinante de colágeno em grânulos, ambos de origem bovina. O rádio esquerdo não recebeu tratamento, sendo considerado controle. Realizaram-se estudos radiográficos e de densitometria óptica por imagens radiográficas no pós-operatório imediato e aos 30, 60 e 90 dias de pós-operatório. Somente no 30º dia de pós-operatório ocorreu maior porcentagem de restabelecimento cortical na fratura tratada com biomaterial. Pela análise estatística não se verificou diferença nos exames densitométricos quer entre momentos ou entre membros. Foi possível concluir que apenas no exame radiográfico ao 30 dias de pós-operatório detectou-se efeito positivo do biomaterial.

Effect of boron and zinc fertilization on white oats grown in soil with average content of these nutrients

The objective of this study was to evaluate the effect of fertilization with zinc or boron on the growth and dry matter production, nutritional value and accumulation of nutrients in white oats. The study comprised two experiments conducted in glasshouses, the first consisting of the application of four doses of zinc (0, 0.2, 0.4 and 0.6 mg/dm³) in the form of zinc sulphate (20% Zn), and the second consisting of the application of four doses of boron (0, 0.2, 0.4 and 0.6 mg/dm³) in the form of Borax (11% B). The experimental design in each case was a randomized block design, with five replicates. Fertilization with zinc and boron increased the growth of white oats, but had no significant effect on the nutritional value of the forage. Higher levels of absorption and accumulation of nutrients in plant tissues were observed following the application of boron and zinc at rates of up to 0.60 mg/dm³ of soil.

Yttrium oxysulfide nanosized spherical particles doped with Yb and Er or Yb and Tm: efficient materials for up-converting phosphor technology field

This work reports on the preparation, structural and luminescent studies of nanosized up-converter phosphors Y2O2S:Yb(4%), Er(0.1%) and Y2O2S:Yb(4%), Tm(0.1%),both from polymeric and basic carbonate precursors. The precursors were submitted to a sulphuration process that was previously developed for oxysulfide preparation from basic carbonate. From XRD data, all phosphors presented the oxysulfide phase and the mean crystallite size estimated from the Scherrer formula in the range of 15-20 nm. Polymeric precursor leads to the smallest crystallite size independent on the doping ion. SEM and TEM results confirmed that basic carbonate leads to spherical particles with narrow size distribution and mean diameter of 150 nm, and polymeric precursor smaller spherical particles with diameter between 20 and 40 nm. Up-conversion studies under 980 nm laser excitation showed that Er-doped phosphors present strong green emission related to H-2(11/2), S-4(3/2) --> I-4(15/2) Er transitions as well as the red ones, F-4(9/2) --> I-4(15/2). Tm-doped samples show strong blue emission assigned to (1)G(4) --> H-3(6) and also the red ones, related to (1)G(4) --> F-3(4). Therefore, the sulphuration method was successfully applied to prepare nanosized and nanostructured blue and green up-converter oxysulfide phosphors starting from basic carbonate and polymeric precursors.

Condições associadas ao grau de satisfação com a vida entre a população de idosos

OBJECTIVE: As a result of overall growing population's life expectancy, it has become increasingly important to ensure not only that the elderly have greater longevity but also happiness and life satisfaction. The objective of the study was to describe factors associated with life satisfaction among elderly people.METHODS: Three hundred and sixty-five older persons, selected by means of random stratified proportional sampling, were interviewed in 2003. The instrument used was a combination of Flanagan and Nahas questionnaires and WHOQOL-100. There were added questions concerning physical activity extracted from International Physical Activity Questionnaire, questions regarding reported morbidity and emotional assessment, sociodemographic condition and an open question. The level of life satisfaction was measured using a scale from one to seven by means of visual recognition. Hierarchical logistic regression analysis was performed including life satisfaction as a dependent variable and those included the final questionnaire, in blocks, as independent variables.RESULTS: Most elderly were generally rather satisfied with life as well as with specific aspects. The level of life satisfaction was associated with: comfort at home (OR=11.82; 95% Cl: 3.27; 42.63); appraising leisure as quality of life (OR=3.82; 95% Cl: 2.28; 6.39); waking up feeling well in the morning (OR=2.80; 95% Cl: 1.47; 5.36); not reporting loneliness (OR=2.68; 95% Cl: 1.54; 4.65); having three or more daily meals (OR=2.63; 95% Cl: 1.75; 5.90) and not reporting Diabetes Mellitus (OR-2.63; 95% Cl: 1.3 1; 5.27).CONCLUSIONS: Most elderly in the study were satisfied with life and their satisfaction was associated with situations related to being well and not being diabetic.

Biomass production and secretion of hydrolytic enzymes are influenced by the structural complexity of the nitrogen source in Fusarium oxysporum and Aspergillus nidulans

The structural complexity of the nitrogen sources strongly affects biomass production and secretion of hydrolytic enzymes in filamentous fungi. Fusarium oxysporum and Aspergillus nidulans were grown in media containing glucose or starch, and supplemented with a nitrogen source varying from a single ammonium salt (ammonium sulfate) to free amino acids (casamino acids), peptides (peptone) and protein (gelatin). In glucose, when the initial pH was adjusted to 5.0, for both microorganisms, higher biomass production occurred upon supplementation with a nitrogen source in the peptide form (peptone and gelatin). With a close to neutrality pH, biomass accumulation was lower only in the presence of the ammonium salt. When grown in starch, biomass accumulation and secretion of hydrolytic enzymes (amylolytic and proteolytic) by Fusarium also depended on the nature of the nitrogen supplement and the pH. When the initial pH was adjusted to 5.0, higher growth and higher amylolytic activities were detected in the media supplemented with peptone, gelatin and casamino acids. However, at pH 7.0, higher biomass accumulation and higher amylolytic activities were observed upon supplementation with peptone or gelatin. Ammonium sulfate and casamino acids induced a lower production of biomass, and a different level of amylolytic enzyme secretion: high in ammonium sulfate and low in casamino acids. Secretion of proteolytic activity was always higher in the media supplemented with peptone and gelatin. Aspergillus, when grown in starch, was not as dependent as Fusarium on the nature of nitrogen source or the pH. The results described in this work indicate that the metabolism of fungi is regulated not only by pH, but also by the level of structural complexity of the nitrogen source in correlation to the carbon source.

Oral health in renal transplant recipients administered cyclosporin A or tacrolimus

OBJECTIVE: the aim of this study was to determine the oral status of renal transplant recipients receiving cyclosporin A (CsA) or tacrolimus (FK-506) as immunosuppressant.SUBJECTS AND METHODS: A total of 88 renal transplant recipients receiving CsA (63 men and 25 women, mean age 51.4 years) and 67 receiving FK-506 (57 men and 10 women, mean age 33.5 years) were included in the study. Donor type, histocompatibility, cold ischemia time and prior delayed graft function were similar between the two groups. Demographics and pharmacological data were recorded for all subjects.RESULTS: the results demonstrated that CsA caused a greater number of oral diseases. A greater number of gingival overgrowth was present in patients treated with CsA. However, the combined use with calcium channel blockers increased the gingival overgrowth number. The occurrence of candida in saliva was observed in 80 renal recipients treated with CsA and 20 treated with FK-506. The presence of squamous oral carcinoma (n = 3) and herpes simplex (n = 10) was observed in patients treated with CsA. These alterations were not observed in renal recipients treated with FK-506.CONCLUSIONS: Renal recipients constitute a high-risk group for oral diseases, as they are immunocompromised. However, the FK-506 regime appears to ameliorate this effect, compared with CsA. Adequate pre- and post-transplant oral health care is recommended for these subjects, irrespective of the time interval for which the drug is administered.

The role of interleukin-10 in the differential expression of interleukin-12p70 and its beta 2 receptor on patients with active or treated paracoccidioidomycosis and healthy infected subjects

Paracoccidioidomycosis patients present an antigen-specific Th1 immunosuppression. To better understand this phenomenon, we evaluated the interleukin (IL)-12 pathway by measuring IL-12p70 production and CD3(+) T cell expression of the IL-12 receptor (IL-12R)beta1/beta2 chains, induced with the main fungus antigen (gp43) and a control antigen, from Candida albicans (CMA). We showed that gp43-induced IL-12p70 production and IL-12Rbeta2 expression were significantly decreased in acute and chronic patients as compared to healthy subjects cured from PCM or healthy infected subjects from endemic areas. Interestingly, the healthy infected Subjects had higher gp43-induced IL12p70 production and beta2 expression than the cured subjects. The addition of a neutralizing anti-IL-10 antibody to the cultures increased IL12p70 levels and beta2 expression in acute and chronic patients to levels observed in Cured subjects. Conversely, addition of the cytokine IL-10 strongly inhibited both parameters in the latter group. In conclusion, we have shown that paracoccidioidomycosis-related Th1 immunosuppression is associated with down-modulation of the IL-12 pathway, that IL-10 may participate in this process, and that patients cured from paracoccidioidomycosis may not fully recover their immune responsiveness.

Food and dietary fiber intake by children with or without constipation. Assessment according to the food guide pyramid and the American Health Foundation (AHF)

We studied the ingestion of 54 children with functional constipation (CC) and 41 without (Control), according to the Food Pyramid. A food frequency questionnaire was used, analyzing fruits with or without peel/bagasse, grains whole or refined, and beans separately. Total subjects and 2-6y CC ingested less DF (g/day) than Control (p < 0.05). The majority had high n degrees of dairy and of the meat group servings, but most groups/subgroups did not meet recommendation for fruit and vegetable. A greater proportion of fruit with peel/bagasse in Control than in CC was almost the only difference for 6-12y. There was a discrepancy between the high percentage of children with DF above AHF recommendation and the high percentage of children who did not meet Pyramid recommendations.

Ovarian follicle diameter at timed insemination and estrous response influence likelihood of ovulation and pregnancy after estrous synchronization with progesterone or progestin-based protocols in suckled Bos indicus cows

The objectives of the present study were to evaluate factors associated with estrous synchronization responses and pregnancy per insemination (P/AI) in Bos indicus beef cows submitted to progesterone-based fixed-time artificial insemination (FTAI) protocols. A total of 2388 cows (1869 Nellore and 519 crossbred Nellore x Angus) from 10 commercial farms were evaluated to determine the relationships among breed, body condition score (BCS) on the first day of the FTAI protocol, the occurrence of estrus between progesterone device removal and FTAI and diameter of largest ovarian follicle (LF) at FTAI on estrous synchronization responses and P/AI. Cows (n=412 primiparous; 1976 multiparous) received an intravaginal device containing progesterone or an ear implant containing norgestomet (a progestin), and an injection of estradiol at the beginning of the estrous synchronization protocol. Body condition was scored using a 1-5 scale on the first day of the FTAI protocol and at 30-60 days postpartum. Females received 300IU of equine chorionic gonadotropin (eCG) and PGF(2 alpha) on the day the progesterone device/implant was removed and were inseminated 48-60h later. At insemination, cows (n=2388) were submitted to an ultrasonographic exam to determine the diameter of the LF. Follicles were classified into four categories based on mean and standard deviation (SD) of the LF (LF1 = two SD below the mean; LF2 = mean minus one SD; LF3 = mean plus one SD; LF4 = two SD above the mean). Ovulation rate was determined in a subset of cows (n=813) by three consecutive ultrasonographic exams: (1) at time of progesterone device/implant removal, (2) at time of FTAI and (3) 48 h after FTAI. Ovulation was defined as the disappearance of a large follicle (>= 8.0 mm) that was previously recorded. Estrus was determined in a subset of the cows (n = 445) by the activation of a detection of estrous patch placed on the tail head on the day of progesterone device/implant removal. Pregnancy was diagnosed 30 days after FTAI. Pregnancy was influenced (P = 0.001) by follicle diameter [LF1 = 27.5% (81/295), LF2 = 46.6% (328/705), LF3 = 57.9% (647/1118), LF4 = 63.3% (171/270)] and the occurrence of estrus [estrus = 67.7% (174/257) and no estrus = 36.2% (68/188)]. Follicle diameter at FTAI influenced ovulation rate [LF1 = 42.5% (34/80), LF2 = 73.9% (161/218), LF3 = 95.8% (407/425), LF4 = 97.8% (88/90)], the occurrence of estrus [LF1 = 54.8% (51/93), LF2 = 33.6% (43/128), LF3 = 68.9% (126/183), LF4 = 90.2% (37/41)] and P/AI among cows that had ovulations [LF1 =32.4% (11/34), LF2 = 50.3% (81/161), LF3 = 60.0% (244/407), LF4 = 68.2% (60/88)]. Improving estrous responses between progesterone device withdrawal and FTAI and increasing the diameter of the LF at FTAI may be important aspects to achieve improved estrous synchronization responses and P/AI following progesterone/progestin and estradiol based FTAI protocols in suckled Bos indicus cows.

Physical and postural aspects of teachers during work activity

Studies indicate that teachers constitute a professional segment, in which the work characteristics and the demands originating from the act of teaching, favor the emergence of sickness, concerning physical or emotional aspects. The present work aimed to describe physical and postural aspects during the working activity of teachers. A total of 120 elementary school teachers (1st to 8th grade) took part in the survey. For data collection, a questionnaire was applied: it included personal and occupational information, perception of discomfort and being off work; physical strength activities; posture at work and physical conditioning activities. The average age of teachers of the present sample corresponds to 35,8 years. In relation to activities which generate more physical strength, the answer none of the activities was predominant with 30 answers; followed by writing on the board, standing up during the period of classes, explanation of the subjects, class elaboration, correction of homework and others. The area of the body with higher amount of occurrences and prevalent discomfort referred to the lower limbs and spinal cord. These data inform the necessity of investing in prevention programs for the teachers, in order to develop strategies into the organizational context and interventions at the work environment.
