Effectiveness of vestibular rehabilitation on postural balance in Parkinson's disease: a systematic review and meta-analysis of randomized controlled trials.

INTRODUCTION: Postural balance impairment can affect the quality of life of patients with Parkinson's disease. Previous studies have described connections of the vestibular system with postural functions, suggesting a potential participation of the basal ganglia in receiving vestibular stimuli. This systematic review aims to summarize the evidence on the effectiveness of vestibular rehabilitation on postural balance in patients with Parkinson's disease. METHODS: A systematic review was conducted using the electronic databases: PubMed, Embase, Scopus and PEDro. The study selection was independently conducted by two reviewers, and disagreements were evaluated by a third reviewer. The included studies had no restrictions on publication dates or languages and the last update occurred in July 2023. RESULTS: From the 485 studies found in the searches, only 3 studies were deemed eligible for the systematic review involving a total of 130 participants. The Berg Balance Scale was described as the tool for evaluation of postural balance in all studies. The meta-analysis showed statistically significant results in favor of vestibular rehabilitation (MD = 5.35; 95% CI = 2.39, 8.31; P < 0.001), regardless of the stage of Parkinson's disease. Although the effect size was suggested as a useful functional gain, the analysis was done with caution, as it only included 3 randomized controlled trials. The risk of bias using the RoB-2 was considered as being of "some concern" in all studies. Furthermore, the quality of the evidence based on the Grading of Recommendations Assessment Development and Evaluation system, produced by pooling the included studies was considered very low. CONCLUSION: Compared to other interventions, vestibular rehabilitation has potential to assist the postural balance of patients with Parkinson's disease. However, the very low quality of the evidence demonstrates uncertainty about the impact of this clinical practice. More robust studies are needed to confirm the benefits of this therapy in patients with Parkinson's disease. This study was prospectively registered in PROSPERO: CRD42020210185.

Screening for coronavirus disease 2019 in pregnant women admitted for delivery: an observational study.

OBJECTIVE: The aim of this study was to examine the impact of symptom-based screening on the prevalence and outcomes of neonatal coronavirus disease 2019 in pregnant women admitted for delivery. METHODS: A retrospective observational study was conducted from June to August 2020 at Gonzaga Mota of Messejana Hospital, Fortaleza, CE, Brazil. All pregnant women were screened for coronavirus disease 2019 based on symptoms. Reverse transcription-polymerase chain reaction or immunology assays for severe acute respiratory syndrome coronavirus 2 were performed when a patient reported a symptom. All newborns of symptomatic patients were submitted for Reverse transcription-polymerase chain reaction. Newborns were divided into groups according to the Reverse transcription-polymerase chain reaction results to identify the relationship between maternal symptoms and neonatal coronavirus disease 2019. RESULTS: A total of 55 (55/1,026, 5.4%) and 50 (50/1,026, 4.8%) pregnant women reported symptoms and had a positive confirmatory test, respectively. The most common symptom of coronavirus disease 2019 among the pregnant women with positive confirmatory test was cough (n=23, 46%). Seven newborns (7/50, 14%) of symptomatic mothers had positive Reverse transcription-polymerase chain reaction. Upon birth, no newborn had serious complications. CONCLUSION: Universal screening of pregnant women admitted for delivery can reduce the perinatal transmission of coronavirus disease 2019. Symptom-based screening can be an alternative for regions with a low prevalence of the disease where a better allocation of financial resources is necessary.

Long latency auditory evokedpotentials in malnourished children / Potenciais evocados auditivos de longa latencia em criancas desnutridas

PURPOSE: To characterize the findings obtained in the long latency auditory evoked potentials in malnourished children, as well as to compare them to the results obtained for children at the same age who present typical development. METHODS: Sixty-five children aged between 7 and 12 years old, of both genders, were evaluated. The control group consisted of 34 children with normal development and the study group consisted of 31 children diagnosed with malnutrition. All children underwent conventional pure tone audiometry, acoustic impedance measurement, dichotic digit test and long latency auditory evoked potentials. RESULTS: The study group presented a statistically significant difference for latencies of the components P1, N1 and P300. The latencies of these components were higher than those of the control group. Concerning the types of alterations found in the study group, increased latency for P1 and P300 and the absence of response in N1 were predominant. The control group showed a statistically significant difference in the amplitude of P300 when compared to the right and left ears. CONCLUSION: Malnourished children present with changes in the long latency auditory evoked potentials, suggesting a deficit in central auditory pathways and alterations in the processing of acoustic information. .

Avaliação comportamental, eletroacústica e eletrofisiológica da audição em crianças desnutridas / Behavioral, electroacoustic and electrophysiological hearing assessment of malnourished children

Introdução: A desnutrição energético-protéica é um dos maiores problemas de saúde pública no Brasil, ocorrendo mais frequentemente em pré-escolares e determinando o comprometimento do crescimento. A desnutrição pode provocar alterações no sistema nervoso central, dependendo da intensidade, da época de incidência e da duração da doença, comprometendo irreversivelmente as funções intelectuais. Levando-se em consideração a importância da integridade do Sistema Auditivo Periférico e Central na aquisição e desenvolvimento de fala, linguagem e aprendizado, torna-se imprescindível que anormalidades auditivas tanto periféricas como centrais sejam identificadas e tratadas precocemente nesta população. Objetivo: Caracterizar os achados das avaliações comportamentais, eletroacústicas e eletrofisiológicas da audição em crianças com desnutrição, bem como compará-los aos obtidos em crianças saudáveis da mesma faixa etária. Métodos: Foram realizados exames de audiometria tonal, logoaudiometria, teste dicótico de dígitos, imitanciometria, potencial evocado auditivo de tronco encefálico (PEATE) e potencial evocado auditivo de longa latência (PEALL) em 31 crianças desnutridas (grupo estudo) e 34 crianças saudáveis (grupo controle), com idade entre 7 e 12 anos, de ambos os gêneros. Resultados: Na análise dos dados quantitativos da audiometria tonal foi observada uma diferença estatisticamente significante entre os grupos para os limiares auditivos nas frequências de 250 e 8000 Hz, tendo o grupo estudo apresentado limiares auditivos mais elevados. Na análise qualitativa, não houve diferença estatisticamente significante entre os grupos, apesar de duas crianças do grupo estudo apresentarem perda auditiva discreta. Na análise dos dados qualitativos, não foram encontradas alterações na logoaudiometria para os dois grupos...

Introduction: Protein-energy malnutrition is a major public health problem in Brazil. It is more frequent among pre-school aged children and it compromises growth. Malnutrition may cause changes to the central nervous system depending on its intensity, time of incidence and duration, irreversibly compromising intellectual functions. Considering the importance of Peripheral and Central Auditory System integrity to the acquisition and development of speech, language and learning, it is crucial that both peripheral and central auditory abnormalities are identified and treated early in this population. Objective: To describe the findings of behavioral, electroacoustic and electrophysiological auditory assessments of malnourished children, as well as comparing them with findings from healthy children within the same age group. Methods: The following tests were performed in 31 malnourished children (study group) and 34 healthy children (control group), aged 7 to 12, from both genders: pure tone audiometry, speech audiometry, dichotic digit test, immittance measures, brainstem auditory evoked potential (BAEP) and long-latency auditory evoked potential (LLAEP). Results: While analyzing quantitative data from pure tone audiometry we observed statistically significant differences between groups for hearing thresholds at frequencies of 250 and 8000 Hz; the study group had higher hearing thresholds. As for quantitative analysis, there was no statistically significant difference between groups, although two children in the study group showed slight hearing loss. While analyzing qualitative data we did not find any changes in speech audiometry in any of the groups. As for the dichotic digit test, there was a statistically significant difference between groups, with a higher proportion of abnormal children in the study group. Both groups showed abnormal immittance measures results, although there was no statistically significant difference between the groups...
