Abstract Introduction Chloroquine and hydroxychloroquine are antimalarial drugs widely used in the treatment of rheumatic diseases. With the global pandemic caused by the new coronavirus, there was an increase in the prescription of these drugs, which led to a major concern regarding their ototoxic effects. Objectives The objective of the present study was to assess existing scientific evidence about the toxic effects of chloroquine and hydroxychloroquine on the peripheral and/or central auditory system. Data Synthesis A systematic literature review was performed by searching the PubMed (Medline), Scopus, Web of Science, LILACS, and SciELO electronic databases, in a search of articles that fullfiled the predefined inclusion and exclusion criteria. The review was conducted in three phases and, in all of them, analyses were performed by two independent researchers. Disagreements were discussed with a third researcher until a consensus was reached. A total of 437 articles were found and 8 were included in this review. Seven of the included studies reported hearing loss in their samples and presented a diagnostic hypothesis of ototoxicity induced by chloroquine or hydroxychloroquine. The most common type of hearing loss was sensorineural, with varying laterality and degrees of severity. The most frequently used audiological test was pure tone audiometry, and only two studies assessed brainstem evoked responses. Conclusion The scientific evidence compiled in this research showed that chloroquine and hydroxychloroquine have an ototoxic effect in the peripheral auditory system. These drugs can cause cochlear damage, including changes in the stria vascularis and lesions in sensory hair cells.

RESUMO Objetivo: investigar protocolos utilizados pela Fonoaudiologia para avaliação da amamentação. Métodos: trata-se de uma revisão integrativa da literatura que objetiva sintetizar evidências disponíveis sobre a avaliação da amamentação no período de 2002 a 2015. Os critérios de inclusão foram artigos científicos que abordassem avaliação da amamentação realizada por fonoaudiólogos, publicados em inglês e português. Trabalhos que não apresentaram resumos na íntegra foram excluídos. Resultados: foram encontrados 140 estudos, dos quais 134 foram excluídos. As seis publicações restantes realizaram avaliação da mamada e foram incluídas neste estudo. Identificaram-se quatro instrumentos de avaliação da amamentação. Os artigos selecionados objetivaram avaliar o conhecimento das mães sobre amamentação e sua relação com a linguagem, a primeira mamada do bebê prematuro, descrever condições iniciais da amamentação, relacionar amamentação com oferta do copo/mamadeira e avaliar características orofaciais e amamentação. Os protocolos avaliaram aspectos do estado de consciência, comportamento e posicionamento do bebê, comportamento da mãe ao amamentar, características da mama, da pega e ordenha e condições após a amamentação. Conclusão: são escassos os estudos na Fonoaudiologia que utilizam protocolos padronizados e validados para avaliação da amamentação. O enfoque maior está na avaliação dos bebês prematuros. Sugere-se que novos estudos sejam realizados, especialmente com foco em validar instrumentos.

ABSTRACT Objective: to investigate protocols used by Speech Therapists to evaluate breastfeeding. Methods: this is an integrative literature review that aims to synthesize available evidence on the evaluation of breastfeeding, from 2002 to 2015. The inclusion criteria were scientific articles that approached breastfeeding evaluation performed by Speech Therapists, published in English and Portuguese. Papers that did not present summaries in their entirety were discarded. Results: a total of 140 studies were found, 134 being excluded. The remaining six publications evaluated breastfeeding and were included in the study with four instruments. The articles selected aimed at evaluating the mothers' knowledge about breastfeeding and its relation to language, the first feeding of the premature baby, describing the initial conditions of breastfeeding, relating breastfeeding to the cup/bottle supply and evaluating orofacial characteristics and breastfeeding. The protocols evaluated aspects of the infant's state of consciousness, behavior and positioning, mother's breastfeeding behavior, breast characteristics, latching and milking, and conditions after breastfeeding. Conclusion: there are few studies in Speech Therapy that use standardized and validated protocols for breastfeeding evaluation. The major focus is on the evaluation of preterm infants. It is suggested that new studies be performed, especially with a focus on validating instruments.

Avaliar os efeitos da suplementação oral de L-carnitina associada ao treinamento físico e muscular respiratório na doença pulmonar obstrutiva crônica (DPOC). Participaram 14 voluntários com idade de 65±10,4 anos e diagnóstico clínico de DPOC moderado, classificados de acordo com a espirometria prévia. Os voluntários foram divididos em grupo treino esteira (GTE) e grupo treino muscular respiratório (GTMR). Realizaram o teste de caminhada de seis minutos (TC6'), teste de caminhada com carga progressiva (TCP), avaliação nutricional do índice de massa corpórea (IMC), dose diária recomendada de L-carnitina, pressões inspiratórias (PImáx) e expiratórias máximas (PEmáx). Fizeram 30 min de caminhada em esteira, 3 vezes/semana por 10 semanas, e o GTMR realizou, ainda, 10 min de treinamento muscular inspiratório (Threshold® IMT) e 10 min de treinamento muscular expiratório (Threshold® PEP) à 50% da PImáx e PEmáx ajustados semanalmente. Após 10 semanas, foram reavaliados. No TC6' pré e pós-programa de treinamento físico, as variáveis alteradas foram: distância percorrida (DP), frequência cardíaca (FC) final, pressão arterial sistólica (PAS) final, pressão arterial diastólica (PAD) final e Borg final no GTMR, no GTE as variáveis alteradas foram FC repouso, FC final, PAS final, Borg repouso e DP. Comparando os grupos no TC6, o GTE apresentou FC final, PAD final e Borg final maiores do que o GTMR na reavaliação; já no TCP, a FC final, PAS final, Borg final foram maiores no GTE, e DP foi maior no GTMR. Na avaliação respiratória, a PEmáx foi maior no GTMR na reavaliação. O treino aeróbio e suplementação de L-carnitina na DPOC otimizou a performance, a capacidade física e a tolerância ao esforço.

To evaluate the effects of oral supplementation of L-carnitine associated with physical and respiratory muscles training in chronic obstructive pulmonary disease (COPD). Participated 14 COPD volunteers (65±10.4 years), divided in group training mat (GTM) and respiratory muscle training group (RMTG). Passed by the six minute walk test (6MWT) and shuttle walk test (SWT), nutritional assessment of body mass index (BMI), dose recommended daily L-carnitine and evaluation of the inspiratory muscle training (IMT) and expiratory muscle training (EMT). They made 30 min walk on a treadmill 3 times/week for 10 weeks, and the RMTG also carried out 10 min with inspiratory muscle training (Threshold® IMT) and 10 min with expiratory muscle training (Threshold® PEP) with 50% of the MIP and MEP adjusted weekly. After 10 weeks, the volunteers were reevaluated. In 6MWT pre and post physical training programs, the variables changed were distance travelled (DT), final cardiac frequency (FCF), final systolic blood pressure (FSBP), diastolic blood pressure (DBP) and final Borg in RMTG. At GTM the variables changed were initial CF, final CF, SBP final, initial Borg and DT. Comparing the groups, we showed that in 6MWT, GTM presented final CF, final DBP and final Borg higher than RMTG in reevaluation. In shuttle walk test, the final SBP and final Borg were higher in GTM, and DT was higher in RMTG. In respiratory evaluation, the MEP was higher in RMTG in reevaluation. The aerobic training and L-carnitine supplementation in COPD patients presented performance optimization, improvement in physical capacity and greater exercise tolerance.
