Proposta de programa de prevenção de perdas auditivas para músicos

INTRODUÇÃO: A audição é um dos sentidos mais importantes para o ser humano, e seu funcionamento está interligado à sua produtividade, o que não é diferente aos músicos, já que ela é de suma importância para a qualidade de seu trabalho e permanência na carreira. O desenvolvimento de um programa de prevenção de perdas auditivas tem por objetivo modificar o comportamento dos músicos em relação à sua audição, uma vez que, constantemente, estão expostos a níveis de pressão sonora elevados e ao surgimento de lesões irreversíveis. Contudo, se medidas preventivas não forem realizadas corretamente, as exposições dos músicos frente à intensidade sonora elevada podem trazer prejuízos à saúde e alguns destes, irreversíveis como, a Perda Auditiva Induzida por Níveis de Pressão Sonora Elevados (PAINPSE) ou Perda Auditiva Induzida por Música (PAIM). OBJETIVO GERAL: submeter os músicos ao programa de prevenção de perdas auditivas (PPPA) e verificar sua eficácia. MATERIAL E MÉTODOS: Participaram componentes de quatro bandas musicais, correspondendo a um total de 16 participantes. Esses membros foram submetidos ao Programa de Prevenção de Perdas Auditivas (PPPA) que engloba as seguintes etapas: (1) medição do nível de pressão sonora no ensaio e show; (2) entrevista específica, Audiometria Tonal Liminar e de Altas Frequências, Logoaudiometria, Imitanciometria e Emissões Otoacústicas por estímulo Transientes e Produto de Distorção; (3) orientação sobre a utilização do Equipamento de Proteção Individual (EPI); e (4) a realização de medidas educativas por meio de workshops. RESULTADOS: O Nível de Pressão Sonora (NPS) durante os ensaios e apresentações/shows, encontram-se elevados, sintomas não auditivos estão presentes em 68, 75% da população total da amostra, presença de zumbido após o show em 100% da amostra; maiores dificuldades de compreensão de fala no ruído nos músicos que tocam baixo (75%). Ao traçar o perfil audiológico do músico foram encontrados: maiores médias dos limiares audiológicos por frequência das bandas estudadas em 500Hz e 3KHz (B1), 3KHz e 4KHz (B2), 3KHz, 4KHz e 6KHz (B3) e em 3KHz (B4); as maiores médias dos limiares audiológicos por frequência dos instrumentos estudados foram em 3KHz, 4KHz e 6KHz (voz), 3KHz e 4KHz (guitarra), 3KHz, 4KHz e 6KHz (baixo) e 3KHz, 4KHz (bateria); presença de entalhe nas frequências de 2KHz, 4KHz, 6KHz e 8KHz na audiometria tonal liminar; já na audiometria de altas frequências em todas as frequências apareceram ao menos um caso, reflexos ausentes em 4KHz (ipsilateral e contralateral); ausência de resposta em 4KHz para todos os baixistas bilateralmente (100%) quando pesquisado EOE por estímulo transiente e na produto de distorção foram encontradas ausência de respostas em 50% da amostra na frequência de 6KHz, sendo assim pesquisada a curva de crescimento (dp growth rate) aparecendo resposta em 75dB em quase 100% dos casos em que houve necessidade de sua realização. Quanto aos achados obtidos da avaliação realizada pelos participantes (músicos) referente ao website, os resultados mostraram que o mesmo atende às necessidades propostas, ou seja, a promoção da saúde auditiva em músicos. CONCLUSÃO: Existe a necessidade de serem tomadas medidas preventivas e a inserção dos músicos em um Programa de Prevenção de Perdas Auditivas (PPPA) a fim de proporcioná-los maiores condições de qualidade de vida e em seu trabalho, já que necessitam da sua audição para desempenhar com eficácia suas atividades e se manter no mercado de trabalho atuando como músico.

PTSD, Depression, and Substance Abuse Symptoms in Women Exposed to Intimate Partner Abuse

The present study explores relationships among several established correlates of trauma in women exposed to intimate partner abuse (IPA), including PTSD, depression, and dissociation symptoms as well as alcohol use as well as other trauma-related variables, such as social support and violence exposure. Two analysis methods were utilized: variable-oriented methods, which examine relationships between variables, and person-oriented analysis methods, which examine groupings of participants within a larger sample (N = 233). Results of the variable-oriented analyses indicated positive links among depression, PTSD, dissociation, and alcohol use in women exposed to IPA, as well as positive links between the aforementioned psychological symptoms and exposure to violence. Social support was related to decreased psychological symptoms. Person-oriented analyses indicated the presence of four unique profiles of women within the larger study sample: Profile 1 (n = 21), which was labeled High Dissociation, Low Depression/PTSD; Profile 2 (n = 150), which was labeled Low Symptoms, High Social Support, Profile 3 (n = 41); which was labeled Low Dissociation, High Depression/PTSD; and Profile 4 (n = 22), which was labeled High Symptoms, Low Social Support. This research supports previous findings about the relationships among several variables related to IPA as well as suggests the need for careful consideration of differences among women within the larger context of research, advocacy, and clinical interventions related to IPA.

The Impact of Prefrontal Cortex "Warm Up" on Immediate Cognitive Reappraisal Ability in Older Adolescents with Elevated Symptoms of Depression

Cognitive Reappraisal (CR) is a central component of Cognitive Behavioral Therapy for adolescent depression. Yet, previous research indicates that a brain region highly associated with successful CR in adults, the Prefrontal Cortex (PFC), is not fully developed until early adulthood. Thus, there is growing concern that CBT interventions directed at building CR abilities in depressed teens might be constrained by PFC immaturity. However, CR is an effective strategy for regulating affect. The current study evaluated an intervention aimed at enhancing CR performance through PFC “warm up” with a working memory task. Additionally, the study examined moderators of intervention response, as well as cognitive correlates of self-reported CR use. Participants included 48 older adolescents (mean age=19.1, 89% female) with elevated symptoms of depression who were randomly assigned to a lab-based WM or control activity followed by a CR task. Overall, results failed to support the effectiveness of “warm up” to augment CR performance. However, current level of depression predicted negative bias and sadness ratings after CR instructions, and this effect was qualified by an interaction with condition. The moderator analysis showed that depressive symptoms interacted with condition such that in the control condition, participants with higher depressive symptoms had significantly lower negative bias scores than individuals with lower depressive symptoms, but this pattern was not found in the experimental condition. Contrary to hypotheses, history of depression did not moderate treatment response. Additional analyses explored alternative explanations for the lack of intervention effects. There was some evidence to suggest that the WM task was frustrating and cognitively taxing. However, irritation scores and overall WM task accuracy did not predict subsequent CR performance. Lastly, multiple cognitive variables emerged as correlates of self-reported CR use, with cognitive flexibility contributing unique variance to self-reported CR use. Results pointed to new directions for improving CR performance among youth with elevated symptoms of depression.

Prospective associations between meth/amphetamine (speed) and MDMA (ecstasy) use and depressive symptoms in secondary school students

Background Research has raised significant concern regarding the affective consequences of synthetic drug use. However, little evidence from well-controlled longitudinal studies exists on these consequences. The aim of this study was to determine whether use of meth/amphetamine (speed) and 63,4- methylenedioxymethamphetamine (MDMA, ecstasy) is independently predictive of subsequent depressive symptoms in adolescents. Methods A sample of 3880 adolescents from secondary schools in disadvantaged areas of Quebec, Canada, were followed over time (2003e2008). Logistic regression was used to test the association between meth/ amphetamine and MDMA use in grade 10 (ages 15e16 years) and elevated depressive symptoms on an abridged Center for Epidemiologic Studies-Depression scale in grade 11, controlling for pre-existing individual and contextual characteristics. Results After adjustment, both MDMA use (OR 1.7, 95% CI 1.1 to 2.6) and meth/amphetamine use (OR 1.6, 95% CI 1.1 to 2.3) in grade 10 significantly increased the odds of elevated depressive symptoms in grade 11. These relationships did not vary by gender or pre-existing depressive symptoms. Increased risk was particularly observed in concurrent usage (OR 1.9, 95% CI 1.2 to 2.9). Conclusions Adolescent use of meth/amphetamine and MDMA (particularly concurrent use) is independently associated with subsequent depressive symptoms. Further enquiry must determine whether these associations reflect drug-induced neurotoxicity and whether adolescence is a period of increased vulnerability to the hazards of synthetic drug exposure.
