Conhecimentos de professores sobre perda auditiva e suas atitudes frente á inclusão

OBJETIVOS: verificar os conhecimentos dos professores sobre a perda auditiva, suas opiniões sobre a educação de alunos com esse tipo de privação sensorial e também conhecer suas atitudes frente à proposta da inclusão. MÉTODOS: participaram desta pesquisa quatro grupos de professores do ensino fundamental, com e sem experiência com aluno com perda auditiva. Os instrumentos utilizados na coleta de dados foram a Escala Lickert de Atitudes Sociais em Relação à Inclusão (ELASI) e um questionário. Comparações entre os resultados de diferentes grupos, por meio de provas estatísticas apropriadas, foram feitas, sempre que a natureza dos dados o recomendava. RESULTADOS: os professores de 1ª a 4ª séries, com e sem experiência com alunos com perda auditiva, apresentaram respostas semelhantes com referência às atitudes sociais acerca da inclusão, tanto na dimensão ideológica quanto na operacional. Professores de 5ª a 8ª séries, com e sem experiência com alunos com perda auditiva, apresentaram respostas semelhantes nos itens ideológicos, porém divergiram nos itens operacionais. em relação aos conhecimentos, os grupos de professores com experiência não apresentaram conhecimentos diferenciados sobre aspectos relativos à perda auditiva, quando comparados com os grupos de professores sem experiência, e todos os grupos enfatizaram os aspectos comunicativos. CONCLUSÃO: a análise revela que os dados provenientes de diferentes instrumentos se complementam e sugerem que os professores são ideologicamente favoráveis à inclusão, entretanto, não têm conhecimentos suficientes para operacionalizar tal proposta.

Aplicação do teste SSW em indivíduos com perda auditiva neurossensorial usuários e não usuários de aparelho de amplificação sonora individual

OBJETIVO: comparar o desempenho de pacientes usuários e não usuários de AASI, por meio do teste SSW. MÉTODO: o estudo foi realizado em 13 sujeitos com idade entre 55 e 85 anos, com perda auditiva bilateral, sendo seis usuários de prótese auditiva bilateral e sete não usuários de prótese auditiva. O teste de processamento auditivo aplicado foi o teste de reconhecimento de dissílabos em tarefa dicótica SSW. Foi realizado um tratamento estatístico feito por meio da técnica Bootstrap e do Teste de Hipótese Kolmogorov-Smirnov. RESULTADOS: o grupo de usuários apresentou melhor desempenho nas condições estudadas do que o grupo de não usuários, principalmente nas condições competitivas. CONCLUSÃO: os resultados obtidos nessa pesquisa apontam para a eficácia do uso do AASI na melhora da compreensão de fala da população estudada, não somente pela compensação da perda auditiva periférica, mas também pela interferência no processo de envelhecimento do sistema nervoso auditivo central.

Perda endógena e exigência de fósforo para mantença de cabritos Saanen

O trabalho foi conduzido com o objetivo de avaliar os efeitos da ingestão de rações com diferentes níveis de fósforo, por cabritos em crescimento, sobre a perda endógena fósforo. Dezoito animais da raça Saanen, machos, castrados, com 4 a 5 meses de idade, peso vivo médio de 25 ± 1,2 kg, foram alojados, por 45 dias, em gaiolas de metabolismo. Os animais receberam rações com três níveis de P (0,08; 0,15; e 0,38% na matéria seca) e semelhantes níveis de proteína bruta, energia metabolizável e relação Ca:P. Após 38 dias de fase pré-experimental, os animais receberam injeção (0,5 mL) com 7,4 Mbq de 32P (Na2HPO4 - livre de carregador), via jugular esquerda. Foram coletados sangue, fezes, urina e sobras das rações. Utilizou-se delineamento inteiramente casualizado, fazendo-se a análise de regressão para o P ingerido. A ingestão média de P variou de 20,9 a 132,3 mg P/kg PV/dia e influenciou a excreção de P fecal. A quantidade de P endógeno variou de 7,6 a 45,4 mg/kg PV/dia e foi também influenciado pela ingestão de matéria seca e P inorgânico no plasma. A exigência líquida de mantença para os caprinos estudados foi de 6,87 mg/kg PV/dia.

Coeficientes de perda de carga em valvulas e acessorios no escoamento laminar de fluidos nao-Newtonianos

Friction loss coefficients for laminar flow of xantan gum solutions (concentrations in the range of 0.1-0.5% by weight) through valves and fittings were experimentally determined. The rheological behavior, studied by means of a concentric cylinder rheometer, was pseudoplastic, being well described by the Ostwald-De Waele model with non-linear correlation coefficients (r) between 0.998 and 0.999. In the pressure drop measurements the following fittings were employed: completely open and half way open ball valve, completely open and half way open angle valve, tee used like coupling, tee used like a 90° elbow, short radius 90° elbow and coupling. The results showed that the friction loss coefficients increased with decreasing generalized Reynolds number. The friction loss coefficients could be well adjusted by a potential model, suggested by Kittredge & Rowley (1957) for Newtonian fluids, K f = A(Re g) -B, with correlation coefficients between 0.837 and 0.999.

Interação entre grau de perda auditiva e o incômodo com zumbidos em trabalhadores com história de exposição ao ruído

Hearing loss and tinnitus impact the lives of workers in every instance of their lives. Aim: this paper aims to investigate the existence of a dose-response relationship between hearing loss and tinnitus by determining whether higher levels of hearing loss can be associated with increased tinnitus-related discomfort. Materials and method: this cross-sectional case study assessed 284 workers exposed to occupational noise through pure tone audiometry. Test results were categorized as defined by Merluzzi. Individuals complaining of tinnitus answered the adapted and validated Brazilian Portuguese version of the Tinnitus Handicap Inventory. A generalized linear model was adjusted for binomial data to test the interaction between these factors. Results: over 60% of the ears analyzed had hearing loss, while more than 46% of them had tinnitus. Tinnitus prevalence and risk rates increased as pure tone audiometry results got worse. The association between both, considering all hearing loss degrees, was statistically significant. Conclusion: the results point to a statistical association between hearing loss and tinnitus; the greater the hearing loss, the greater the discomfort introduced by tinnitus. 2009 © Revista Brasileira de Otorrinolaringologia.

Estudo da perda da tensao do enxerto de tendão calcâneo bovino

Lesion of the anterior cruciate ligament (ACL) in the knee is a problem that affects animals as well as humans and may evolve with joint instability that is often symptomatic and incapacitating. The main option for ligament substitution is the autologous tendon graft. The graft undergoes tensioning during ACL reconstructive surgery to reestablish the normal laxity of the ACL- deficient knee. Although graft tensioning plays a fundamental role in postoperative clinical evolution, ideal tensioning levels have not been established in the literature. Therefore, graft elongation that may occur over time is still one of the main reasons for ligament reconstruction failure. In this study, ten bovine calcaneus tendons underwent two successive assays of physiological tensioning for a maximum deformation of 2.5% of the initial tendon length, maintained for 600s with force (N) values recorded at zero time (initial), 300s and 600s. At the end of the first assay, the tendon returned to its initial length and was maintained at rest for 300s and then the next tensioning assay was initiated, repeating the previous procedure. Statistical analysis revealed that tendon elongation is more pronounced during the initial 300s, reflecting a more accentuated decline in the tension values of the graft. Therefore, 300s after tensioning and fixing the graft, the surgeon can assess with more precision if the tensioning level was adequate.

Lipoperoxidação, perda de viabilidade celular e diminuição da liberação de IL-8 de neutrófilos humanos na presença de corpos cetônicos

Type-1 diabetes patients suffer from frequent episodes of acidosis caused by an increased fatty acid metabolism and consequently increased plasma level of acetoacetate (AcAc) and β-hydroxybutyrate (β-HOB). This article describes a study of the effects of pathological concentrations of AcAc and β-HOB on lipoperoxidation, cell viability and the release of the CXCL8 (IL-8) cytokine by activated neutrophils. Neutrophils from healthy donors were isolated by density gradient (Histopaque® 1077/1119) and incubated with the ketone bodies. Lipoperoxidation was determined as thiobarbituric acid reactive substances (TBARS). The cell viability was evaluated by the release of intracellular lactate dehydrogenase. The release of CXCL8 was measured by ELISA in a 24-h culture of opsonized zymosan-stimulated neutrophils. AcAc, but not β-HOB, provoked a dose-dependent increase in the neutrophil membrane lipoperoxidation (p<0.05; r =0.9915). In the cytotoxicity assay, a dose-dependent release of LDH was observed when the neutrophils were incubated with AcAc in concentrations up to 40 mM (p<0.05). β-HOB was devoid of effect. The release of CXCL8 was inhibited by AcAc and β-HOB in a dose-dependent manner. In conclusion, these results suggest that the accumulation of ketone bodies in diabetic patients could be involved in their usually increased susceptibility to infection.

Evolução da perda de peso entre indivíduos da fila de espera para a cirurgia bariátrica em um ambulatório multidisciplinar de atenção secundária à saúde

Objective: The objective of this study is to characterize the assistance and analyze patient's adherence to nutritional follow-up while in the waiting line for bariatric surgery in a multidisciplinary, secondary healthcare outpatient clinic. Methods: This retrospective study was based on the nutritional records of 59 patients subjected to bariatric surgery at the Hospital das Clinics de Botucatu, from 2001 to 2008. The population studied was distributed into 8 groups and analyzed according to follow-up duration. The analysis took into account the evolution of body weight and the number of follow-up visits in a given period. The Kruskal-Wallis test was used to compare data between groups while Spearman's coefficient was used to test correlations. Results: Among the 59 studied patients, 42 (71.2%) returned to the clinic at least once in six months. Of these, 67.8% lost weight while in the waiting line and 27.1% of them lost more than 10% of their body weight. The greatest weight losses in the preoperative period were found in the groups that had more than six months of nutrition follow-up. There was a mean delay of three months between return visits, which could have contributed to the low adherence to follow-up. Conclusion: The patients in the waiting line for surgery analyzed in this study presented low adherence to the long-spaced return visits. The greatest weight losses were observed in groups that had been followed for more than six months. This shows that, to achieve the desired weight loss and an adequate education process before surgery, at least six months of follow-up and regular visits are necessary.

Qualidade de vida e sobrecarga de trabalho em cuidadores de idosos em seguimento ambulatorial

We evaluated the quality of life related to health and work overloads among 126 caregivers to patients at two geriatric outpatient clinics of a university hospital, as well as the association between overloads and demographic and clinical variables, using an exploratory, descriptive, cross sectional and quantitative approach. The Zarit Burden Interview, a socio-demographic and clinical characterization instrument, was used to assess perceived workloads and the Medical Outcomes Study Short-Form Health Survey (SF-36) was used to assess quality of life related of health. Descriptive, comparative, correlative, and multivariate data analyses were carried out. There was significant difference between two outpatient caregiver workloads; all socio-demographic aspects and variables related to care were associated to worsening at least one dimension of the SF-36; frequent illnesses among caregivers were related to a worsening of their quality of life related to health, demonstrating the wear experienced by caregivers to the elderly in these health care units.

Perda e luto: Vivências de mulheres que interromperam a gestação por malformação fetal letal

The scope of this study was to investigate the grieving experiences of women who terminated pregnancies under judicial authorization, due to life-incompatible fetal malformation. Ten women attended in the Fetal Medicine Department of Botucatu Clinical Hospital participated in the study. Data collection was conducted by means of semi-structured interviews forty days after termination. The interviews were recorded and transcribed in full, with the data analyzed from the thematic content analysis perspective. The results revealed that the mothers sought explanations and meanings for the loss, with religious responses and self-blame being very frequent. The reports were marked by feelings of sadness, longing and sensations of emptiness due to the loss of the child, revealing the need of the mothers to dwell on the issue. The mothers were and continued to be linked to their children; the termination of the pregnancy, although being a choice to minimize the pain of an inevitable loss, did not spare the women from experiences of great suffering. The study includes input for the discussion and planning of health approaches and care for women who terminate their pregnancy due to lethal fetal malformation, by means of judicial authorization.
