Effects of indirect vocal therapy via telehealth in speech-language therapy on self-assessment and vocal quality of physical education professionals / Efeitos da terapia vocal indireta via telefonoaudiologia na autoavaliação e qualidade vocal de profissionais da educação física

ABSTRACT Purpose: this study aimed to verify the effects of indirect vocal therapy (IVT), via telehealth, in physical education professionals in voice self-assessment, as well as vocal quality. Methods: 16 physical education professionals, aged between 18 and 50 years, both sexes, participated in the study. All participants were submitted to eight IVT sessions twice a week, 30 minutes each, remotely. The assessments happened remotely, too. Vocal health was explained to modify vocal habits and general health, coping strategies, stress management, and therapeutic interaction. The following protocols were applied: Vocal Disorders Screening Index, Voice Symptoms Scale (VoiSS), Voice Handicap Index (VHI), and vocal recording (/a/ and counting) was performed, evaluating the general degree of vocal quality, pre and post-IVT. The Wilcoxon Test (p<0.05) was applied to verify the findings. Results: there was a significant decrease in the values of the VoiSS protocol (total p=0.041; limitation p=0.032), and VHI (total p=0.012; p=0.005), and in the general degree of vocal quality in vowel /a/ (p=0.011). Conclusion: IVT applied through telehealth in physical education professionals, has positive effects on vocal and laryngopharyngeal symptoms, improving the self-perception of voice handicaps. IVT significantly improved the general degree of vocal quality, only in the emission of the sustained vowel.

RESUMO Objetivo: este estudo objetivou verificar os efeitos da terapia vocal indireta (TVI), aplicada via telefonoaudiologia, em profissionais da educação física na autoavaliação e qualidade vocal. Métodos: 16 profissionais da Educação Física, com idades entre 18 e 50 anos, de ambos os sexos, participaram do estudo. Foram submetidos a oito sessões de TVI, duas vezes/semana, 30 minutos cada. As sessões e avaliações foram ministradas à distância. Foram trabalhados conhecimento sobre saúde vocal, para modificar hábitos vocais e de saúde geral, estratégias de enfrentamento, gerenciamento de estresse e interação terapêutica. Aplicaram-se protocolos: Índice de Triagem de Distúrbios Vocais, Escala de Sintomas Vocais (ESV), Índice de Desvantagem Vocal (IDV) e gravação vocal (/a/ e contagem), avaliando-se o grau geral da qualidade vocal, pré e pós TVI. Utilizou-se o Teste de Wilcoxon (p<0,05) nas comparações. Resultados: houve diminuição significante nos valores dos protocolos ESV (total p=0,041; limitação p=0,032), IDV (total p=0,012 e orgânico p=0,005), e no grau geral da qualidade vocal na vogal (p=0,011). Conclusão: a TVI aplicada por meio da telefonoaudiologia, em profissionais da Educação Física, tem efeitos positivos nos sintomas vocais/laringofaríngeos, melhorando a autopercepção da desvantagem vocal. A TVI melhorou significantemente o grau geral da qualidade vocal, apenas na emissão da vogal sustentada.

Clinical and laboratory characteristics, staging, and outcomes of individuals with AIDS-associated Kaposi's sarcoma at an university hospital

Abstract: Background: Kaposi's sarcoma continues to be the most common human immunodeficiency virus - associated neoplasm with considerable morbidity and mortality. Objective: To describe the clinical and laboratory characteristics, initial staging, and outcomes of aids patients with Kaposi's sarcoma at an university hospital of Recife, Pernambuco. Methods: This is a descriptive study with analytic character, retrospective, of a case series between 2004 and 2014. Results: Of the 22 patients included in the study, 20 were aged <40 years (72.7%). The majority had CD4+ T lymphocyte counts of <200 cells/mm3 (77.3%) and human immunodeficiency virus loads of <100,000 copies/mL (78.9%). Lesions were most commonly observed on the skin (90%), and internal organs were affected in 11 of the 22 patients. Only 7 (31.8%) of the 22 patients were undergoing antiretroviral therapy (ART) at the time of Kaposis sarcoma diagnosis, and the initial disease staging classification was high risk (Aids Clinical Trials Group Oncology Committee) in 19 of the 22 patients (86.4%). Regarding Kaposi's sarcoma treatment, 17 of 22 patients (77.3%) underwent systemic chemotherapy + ART and 5 were treated exclusively with ART. Eight of the 22 patients died (36.5%); of these, 87.5% had died within one year of Kaposi's sarcoma diagnosis. Limitation of the study: Without a control group, this study cannot be used to generate hypotheses. Conclusions: Despite the association between aids and late Kaposi's sarcoma diagnosis in the study population, including an unfavorable risk at the time of staging, a lower mortality rate was observed relative to other studies; this might be related to access to a specialized health service.

Abscess resulting from Mycobacterium kansasii in the left thigh of AIDS patient

A case of abscess resulting from Mycobacterium kansasii, in the left thigh of a 53-year-old woman infected with the Human Immunodeficiency virus, is reported. Curiously, there was no pulmonary or systemic involvement as is usual with these Mycobacterium infections. The patient had CD4 T lymphocyte count of 257 cells/µL and a viral load of 60,154 copies. Despite presenting a relatively preserved immunity, the patient also presented Criptococcic meningoencephalitis and Esophageal candidiasis. The patient responded satisfactorily to treatment for infections and after 51 days was discharged.

Repercussões da cardiomegalia na função pulmonar de indivíduos adultos com insuficiência cardíaca crônica: uma revisão sistemática / Repercussions of the cardiomegaly on the pulmonary function of adult individuals with chronic heart failure: a systematic review

Para analisar as repercussões da cardiomegalia sobre a função pulmonar em indivíduos adultos com insuficiência cardíaca (IC) crônica, foram revisados artigos nas bases PUBMED, BIREME, ISI Web of Knowledge e COCHRANE, publicados na última década, estudos observacionais e sem restrição de idioma. Utilizados os descritores “cardiomegaly” e “Respiratory Function Tests”, e negada a palavra “exercise”. Foram incluídos artigos com IC crônica, de ambos os sexos, entre 19 e 64 anos, incluindo IC congestiva e cardiomiopatia dilatada e excluídos com IC aguda, com avaliações pós-intervenção clínica ou por exercício. Para avaliar a qualidade dos artigos foi utilizada a escala da Agency for Healthcare Research and Quality (AHRQ) e aceitos aqueles com escore>50 pontos (0-100). Foram selecionados cinco artigos do total de 1093 e agrupados por parâmetros relacionados aos fluxos e volumes pulmonares, padrão ventilatório e desempenho muscular. Na AHRQ, dois estudos ficaram na faixa de 50-75% e os demais >75%. Eles apontam para redução da capacidade vital inspiratória (CVI), volume expiratório forçado no 1o segundo (VEF1) e pressão inspiratória máxima (PImáx) em função da cardiomegalia, com discreta redução na relação VEF1/CVI e na capacidade de difusão para monóxido de carbono (DLCO). Portanto, segundo os estudos, a cardiomegalia leva a um padrão respiratório restritivo, com redução do volume alveolar que interfere na DLCO. As correlações mais fortes envolvem a redução da PImáx, CVI e VEF1.

To analyze the repercussions of the cardiomegaly on lung function in adults with chronic heart failure (CHF), the databases PUBMED, BIREME, ISI Web of Knowledge and COCHRANE were considered to review observational studies published in the last decade without language restriction. It was used the descriptors "cardiomegaly" and "respiratory function tests", and denied "exercise". It was included papers with CHF, of both sexes between 19 and 64 years accepting samples with congestive HF and dilated cardiomyopathy and excluding with acute heart failure, post-intervention assessment clinic or by exercise. The quality of papers was evaluated by using the scale of Agency for Healthcare Research and Quality (AHRQ) and accepted papers with score >50 points (0-100). We selected 5 studies from total of 1093 and grouped by parameters related to flows and lung volumes, respiratory pattern and muscle performance. At AHRQ, two studies were in the range of 50-75% and the others >75%. These studies showed lower inspiratory vital capacity (IVC), forced expiratory volume in 1st second (FEV1) and maximal inspiratory pressure (PImáx) as a function of cardiomegaly, with a slight reduction in the ratio VEF1/IVC and diffusion capacity for carbon monoxide (DLCO). Therefore, the studies suggest that the cardiomegaly leads to a restrictive lung pattern, with reduction in alveolar volume that interferes with DLCO. The strongest correlations involve the reduction of PImáx, IVC and FEV1 in this population.

Produção e caracterização de anticorpos monoclonais contra toxina épsilon de Clostridium perfringens Tipo D / Production and characterization of monoclonal antibodies against Clostridium perfringens Type D epsilon toxin

Clostridium perfringens tipo D é o agente etiológico da enterotoxemia em ruminantes, causada pela toxina épsilon e caracterizada por edema cardíaco, pulmonar, renal e cerebral. Anticorpos monoclonais contra toxina épsilon de C. perfringens tipo D foram produzidos a partir da fusão da linhagen de mieloma P3-X63-Ag8 653 com células do baço de camundongos Balb/c imunizados com o toxóide épsilon. Seis linhagens de híbridos secretores de anticorpos monoclonais das classes e IgM e IgG foram estabelecidas.

Clostridium perfringens type D is the aetiological agent of enterotoxemia in ruminants. The disease is caused by epsilon toxin characterized by cardiac, pulmonary, kidney and brain edema. Monoclonal antibodies were produced by using myeloma cell line P3-X63-Ag8 653 fused with spleen cells from Balb/c mice, immunized with epsilon toxoid of C. perfringens type D. Six hybrids were established secreting monoclonal antibodies of the IgM class and IgG3 subclass.

Botulismo em ruminantes causado pela ingestão de cama-de-frango / Botulism in ruminants being fed with poultry litter

Botulismo é uma intoxicação causada pela ingestão das toxinas produzidas pelo Clostridium botulinum, que acomete mamíferos e aves. Neste trabalho é descrito um surto de botulismo em ruminantes, ocorrido em duas propriedades localizadas no município de Patos, no Estado da Paraíba, Brasil. Em uma das propriedades, de um total de 88 bovinos, 85 (96,6 por cento) vieram a óbito. Na segunda, morreram 145 ovinos (96,7 por cento), 233 caprinos (57,8 por cento) e 30 bovinos (96,8 por cento). Os animais acometidos apresentavam paralisia progressiva, dificuldade de locomoção, sialorréia e dispnéia. A morte ocorreu entre 24 e 48 horas após o início dos sinais, por parada cardio-respiratória. Nenhuma alteração significativa foi observada no exame post-mortem. O diagnóstico de botulismo foi confirmado pela demonstração das toxinas C e D no conteúdo intestinal e na cama-de-frango utilizada na alimentação dos animais, pela técnica de soroneutralização em camundongos.

Botulism is a poisoning caused by the ingestion of toxins produced by Clostridium botulinum, that infects mammals and birds. This article reports an outbreak of botulism in two different flocks of ruminants at Paraíba, Brazil. In one, 85 out of 88 (96.6 percent) cattles died. In the other, 145 (96.7 percent) sheeps, 233 (57.8 percent) goats and 30 (96.8 percent) cattles died. Clinical signs were progressive paralysis, difficulties in moving, sialorrhoe and dyspnoe. Death occurred 24 to 48 hours after the beginning of clinic signs and at post-mortem examination no noteable changes were observed. Type C and D toxins were demonstrated in the intestinal contents and poultry litter by neutralization test in mice.

Reproductive aspects of the mosquito Culex quinquefasciatus (Diptera:Culicidae) infected with Wuchereria bancrofti (Spirurida: Onchocercidae)

This study reports on the relationship between Wuchereria bancrofti infection and female body size, intake of blood and fecundity in the mosquito Culex quinquefasciatus, vector of this filarial parasite in Recife (Brazil). Adults from field collected larvae were infected via a membrane feeding procedure, using blood with parasitaemia ranging from 724-6,000 mf/ml. A positive correlation was observed between mosquito size (measured by wing length) and egg production in uninfected females. However, this relationship did not exist in W. bancrofti infected mosquitoes. This change is unlikely to be the result of changes in blood ingestion as no significant difference was found when infected and uninfected females were compared. Variation in egg production observed between trials could not be associated with parasite density in the blood. These results suggest infection with W. bancrofti may disrupt the relationship between mosquito size and egg production during the first gonotrophic cycle of C. quinquefasciatus such that fecundity is sometimes reduced. However, this overall affect is variable and many groups of mosquitoes do not respond in this way
