Bilateral Globus Pallidus Externus Deep Brain Stimulation for the Treatment of Refractory Tourette Syndrome: An Open Clinical Trial.

OBJECTIVES: We have previously proposed that Tourette syndrome (TS) is the clinical expression of the hyperactivity of globus pallidus externus (GPe) and various cortical areas. This study was designed to test this hypothesis by verifying the efficacy and safety of bilateral GPe deep brain stimulation (DBS) for treating refractory TS. MATERIALS AND METHODS: In this open clinical trial, 13 patients were operated on. Target coordinates (center of GPe) were obtained by direct visualization. Physiological mapping was performed with macrostimulation and microrecording. Primary and secondary outcome measures were, respectively, responder and improvement rates of TS and comorbidities, according to pre- and postoperative scores on the following assessment instruments: Yale Global Tic Severity Scale, Yale-Brown Obsessive Compulsive Scale, Beck Depression Inventory/Hamilton Depression Rating Scale, Beck Anxiety Inventory/Hamilton Anxiety Rating Scale, and Concentrated Attention test. RESULTS: Intraoperative stimulation (100 Hz/5.0V) did not produce any adverse effects or impact on tics. Microrecording revealed bursting cells discharging synchronously with tics in the central part of the dorsal half of GPe. Patients were followed up for a mean of 61.46±48.50 months. Responder rates were 76.9%, 75%, 71.4%, 71.4%, and 85.7%, respectively, for TS, obsessive-compulsive disorder (OCD), depression, anxiety, and attention deficit hyperactivity disorder. Mean improvements among responders in TS, OCD, depression, and anxiety were 77.4%, 74.7%, 89%, and 84.8%, respectively. After starting stimulation, tic improvement was usually delayed, taking up to ten days to manifest. Afterward, it increased over time, usually reaching its maximum at approximately one year postoperatively. The best stimulation parameters were 2.3V to 3.0V, 90 to 120 µsec, and 100 to 150 Hz, and the most effective contacts were the two dorsal ones. Two complications were registered: reversible impairment of previous depression and transient unilateral bradykinesia. CONCLUSIONS: Bilateral GPe-DBS proved to be low risk and quite effective for treating TS and comorbidities, ratifying the pathophysiological hypothesis that led to this study. Moreover, it compared favorably with DBS of other targets currently in use.

Toll-like receptor 10 controls TLR2-induced cytokine production in monocytes from patients with Parkinson's disease.

Peripheral inflammation, particularly mediated by monocytes, can cause neuroinflammation in Parkinson's disease (PD). We investigated the mechanism of TLR2-induced cytokine impairment in peripheral monocytes from PD patients and the association between the presence of CD14+ TLR10+ monocytes and PD severity. Peripheral blood mononuclear cells from PD patients and healthy individuals were evaluated for TLR expression on monocyte subsets (CD14 and CD16 expression) using flow cytometry. Moreover, cytokines were evaluated using flow cytometry after stimulation with Pam3 Cys (TLR2/TLR1 agonist) in the absence or presence of neutralizing antibodies to TLR10. The severity of PD was assessed using the unified PD rating scale (UPDRS) and motor activity, anxiety (BAI), depression (BDI), and fatigue (PD Fatigue Scale-16) scales. The frequency of CD14+ TLR10+ monocytes and expression intensity of TLR2 and TLR10 were higher in patients with PD than healthy individuals. The frequency of intermediate monocytes (CD14++ CD16+ ) was not significantly increased in patients with PD, but was the main monocyte subset expressing TLR10. The TLR2/TLR1-impaired cytokine production (IL-6, TNFα, IL-8, and IL-10) in PD patients was reversed by neutralizing TLR10. The high frequency of total CD14+ TLR10+ monocytes was associated with a reduction in the severity of PD according to the evaluation of motor and nonmotor symptoms. Peripheral monocytes from patients with PD showed phenotypic and functional alterations. The expression of TLR10 on monocytes can protect against PD by controlling TLR2-induced cytokine production. Furthermore, data suggested that a low frequency of CD14+ TLR10+ monocytes indicates the severity of PD. The results identified new opportunities for the development of novel PD neuroprotective therapies.

TLR4 and TLR2 activation is differentially associated with age during Parkinson's disease.

Parkinson's disease (PD) is an age-related neurodegenerative disease characterized by loss of dopaminergic neurons associated with neuroinflammation. Toll-like receptors (TLRs) are expressed in peripheral blood leukocytes and also in neurons and glial cells mediating inflammation. This study aimed to investigate the peripheral blood leukocyte response to TLR2 and TLR4 agonists in young and elderly PD patients. Two groups of patients with PD were evaluated (≤ 55 years old and ≥ 65 years old), age-matched with healthy controls (n = 26). Severity of PD was evaluated by Unified Parkinson's Disease Rating Scale (UPDRS). Whole blood cultures were stimulated with lipopolysaccharide (LPS), a TLR4 agonist or Pam3Cys (Pam), a TLR2 agonist. Tumor necrosis factor alpha (TNFα) and interleukin 10 (IL-10) were measured by immunoenzimatic assay. 6 h-TNFα production was increased after TLR4 stimulation, mainly in young PD patients, whereas TLR2-induced TNFα and IL-10 levels were decreased in PD patients independent of age (p < 0.05). A reverse correlation between LPS-induced TNFα production and age was observed in PD patients and controls, but TNFα induced by TLR2 agonist was not associated with age of PD patients or controls. TNFα production induced by TLR4 but not by TLR2 was reversely associated with the age at PD onset and disease duration. No associations between UPDRS scores and cytokine levels were detected. In conclusion, TLR4 and TLR2 responses seem to be differentially affected during PD. Data suggest that TLR2 deficiency in periphery is independent of age of the patients, age at PD onset, or PD duration.

Cognitive evaluation of patients with glaucoma and its comparison with individuals with Alzheimer's disease.

PURPOSE: To evaluate the cognitive performance of patients with glaucoma and compare it to individuals with Alzheimer's disease (AD). METHODS: This is a prospective, cross-sectional and case-control study. All subjects were assessed using the Mini-Mental State Examination (MMSE) and its subtests verbal fluency, word list memory, delayed recall of the word list, word list recognition test, Boston naming and constructive praxis from Consortium to Establish a Registry for Alzheimer's Disease (CERAD). The results were compared among the groups. RESULTS: A total of 50 healthy elderly with a mean age of 71.2 ± 5.2 years; 41 patients with glaucoma (72.2 ± 4.4 years); and 21 patients with AD (79.0 ± 7.6 years) were included. There was a reduction in all cognitive assessment tests evaluated, both for patients with glaucoma, and for those with AD compared with controls (p < 0.001 for all). Comparing the patients with glaucoma and AD, it was noted that the last had lower cognitive function (p < 0.001), except for the CERAD tests Boston (p = 0.1) and praxis (p = 0.6). Glaucoma patients, however, presented results of cognitive tests similar to those described for patients with mild AD, including lower values for MMSE (21.9 ± 3.7), Boston (10.6 ± 2.6) and praxis (5.9 ± 2.3). CONCLUSION: Glaucoma patients had reduction in cognition when compared to normal individuals. They were similar to the values reported in the literature for patients with mild AD, mostly, and also in some subjects with the presence of advanced AD.

Decreased Toll-Like Receptor 2 and Toll-Like Receptor 7/8-Induced Cytokines in Parkinson's Disease Patients.

OBJECTIVES: Toll-like receptors (TLRs) are expressed in several immune cells including blood monocytes and resident macrophages, such as microglia in the central nervous system. TLRs recognize pathogen- or damage-associated molecular patterns, leading to the release of inflammatory and toxic molecules, which can contribute to neuroinflammation associated with Parkinson's disease (PD). The aim of this study was to compare the potential of peripheral blood cells from PD patients or healthy subjects to produce cytokines after exposure to TLR agonists, and to investigate TLR2 and TLR4 expression on monocyte subsets. METHODS: Twenty-one patients and 21 healthy controls were recruited. Patients were evaluated according to the Unified Parkinson's Disease Rating Scale, and Hoehn and Yahr stage. Cytokines were measured in supernatants of whole blood cultures after incubation with TLR2, TLR4, or TLR7/8 agonists, by cytometric bead array. Expression of CD14, CD16, TLR2, and TLR4 was analyzed by cytometry. RESULTS: Patient blood cells produced lower levels of cytokines in response to TLR2 and also after TLR7/8/R848 activation than controls. Percentages of CD14+CD16+ or CD14+CD16- monocytes and TLR2 and TLR4 expression were similar between patients and controls. CONCLUSIONS: Blood leukocyte TLR2 and TLR7/8 responses are impaired in PD. This was neither associated with imbalance in monocyte subsets nor with TLR2/TLR4 expression on these cells. The association between a decreased TLR response in periphery and damage of brain in PD must be further investigated.

Striatal somatotopy and motor responses evoked by acute electrical stimulation of the posterior striatum in rats.

INTRODUCTION/OBJECTIVES: Previous experiments suggest that the striatal sensorimotor territory in rats is located in its dorsolateral region, along the rostrocaudal axis, unlike what has been observed in primates. In the present study, electrical stimulation was performed to investigate the degree of participation of the posterior striatum in its motor territory, its somatotopic organization, and the motor responses evoked by stimulation. METHODS: Twenty-five rats were submitted to stereotactic stimulation of the posterior striatum under general anesthesia, receiving consecutively four different current intensities. The motor responses observed in the different body parts were registered for later comparison. We considered as threshold the smallest of these current intensities able to evoke a motor response. RESULTS: The observed motor responses were qualitatively different for each segment: forepaws: ipsilateral, adduction, and contralateral abduction; hindpaws: ipsilateral, flexion, and contralateral, extension/abduction; trunk, rotation/flexion; and tail, rotation/elevation. High-frequency, small-amplitude distal tremor occurred in the ipsilateral forepaw in 95% of the animals. Progressively larger current intensities were necessary for the induction of motor response in the forepaws, hindpaws, and trunk/tail, in that order. CONCLUSIONS: The results allowed us to infer the following posterior striatal somatotopic organization: forepaws, posterolaterally, being the contralateral medial to the ipsilateral; trunk/tail, anteromedially; and hindpaws, in an intermediate position, being the contralateral posterior to the ipsilateral. It is suggested that the tremor and the other observed motor responses derive from the excitation of striatal projection neurons and that the striatum may play an important role in the genesis of essential tremor.

Expanding the phenotypic spectrum of CLCN2-related leucoencephalopathy and ataxia.

Mutations in CLCN2 are a rare cause of autosomal recessive leucoencephalopathy with ataxia and specific imaging abnormalities. Very few cases have been reported to date. Here, we describe the clinical and imaging phenotype of 12 additional CLCN2 patients and expand the known phenotypic spectrum of this disorder. Informed consent was obtained for all patients. Patients underwent either whole-exome sequencing or focused/panel-based sequencing to identify variants. Twelve patients with biallelic CLCN2 variants are described. This includes three novel likely pathogenic missense variants. All patients demonstrated typical MRI changes, including hyperintensity on T2-weighted images in the posterior limbs of the internal capsules, midbrain cerebral peduncles, middle cerebellar peduncles and cerebral white matter. Clinical features included a variable combination of ataxia, headache, spasticity, seizures and other symptoms with a broad range of age of onset. This report is now the largest case series of patients with CLCN2-related leucoencephalopathy and reinforces the finding that, although the imaging appearance is uniform, the phenotypic expression of this disorder is highly heterogeneous. Our findings expand the phenotypic spectrum of CLCN2-related leucoencephalopathy by adding prominent seizures, severe spastic paraplegia and developmental delay.

Effects of unilateral stereotactic posterior striatotomy on harmaline-induced tremor in rats.

Although long known and the most prevalent movement disorder, pathophysiology of essential tremor (ET) remains controversial. The most accepted hypothesis is that it is caused by a dysfunction of the olivocerebellar system. Vilela Filho et al. [2001; Stereotact Funct Neurosurg 77:149-150], however, reported a patient with unilateral hand ET that was completely relieved after a stroke restricted to the contralateral posterior putamen and suggested that ET could be the clinical manifestation of posterior putamen hyperactivity. The present study was designed to evaluate this hypothesis in the most often used model of ET, harmaline-induced tremor in rats. Fifty-four male Wistar rats were randomly distributed into three groups: experimental (EG), surgical control (SCG), and pharmacological control (PCG) groups. EG animals underwent stereotactic unilateral posterior striatotomy. SCG rats underwent sham lesion at the same target. PCG served exclusively as controls for harmaline effects. All animals received, postoperatively, intraperitoneal harmaline, and the induced tremor was video-recorded for later evaluation by a blind observer. Thirteen animals were excluded from the study. Limb tremor was reduced ipsilaterally to the operation in 20 of 21 rats of EG and in two of nine of SCG, being asymmetric in one of 10 of PCG rats. Comparisons between EG × SCG and EG × PCG were statistically significant, but not between SCG × PCG. Limb tremor reduction was greater in anterior than in posterior paws. Lateral lesions yielded better results than medial lesions. These results suggest that the posterior striatum is involved with harmaline-induced tremor in rats and support the hypothesis presented.

Possible mechanisms involved in subthalamotomy-induced dyskinesia in patients with Parkinson's disease.

BACKGROUND/AIMS: Operation-induced dyskinesia (OID) occurs in approximately 10% of patients submitted to subthalamotomy. The goal of the authors was to determine the possible causes of this feared complication. METHODS: The 54 patients who underwent unilateral subthalamotomy were divided into two groups: the OID group (OIDG), composed of 6 patients who developed dyskinesia following the operation, and the control group (CG), consisting of 48 patients who did not present this complication. The two groups were compared regarding age; sex; presence of levodopa-induced dyskinesia (LID) and/or stimulation-induced dyskinesia (SID); side of the operation; territories of the subthalamic nucleus (STN) involved by the lesion, and degree of lesion extension towards the zona incerta (ZI). RESULTS: The lesion involved the dorsolateral territory of the STN and was almost completely restricted to this nucleus in all patients of the OIDG, while it spread to the ZI in all but 1 patient of the CG. SID was significantly (p < 0.05) more frequent in the OIDG. There was also a strong trend favoring LID (p = 0.055). CONCLUSIONS: Damage to the dorsolateral territory of the STN and sparing of the ZI seem to be essential for the development of OID. SID and, to a lesser extent, LID are apparently significant risk factors for the development of this complication.

Definitions, phenomenology, diagnosis, and management of the disorders of laughter and crying in amyotrophic lateral sclerosis (ALS): Consensus from ALS and Motor Neuron Disease Scientific Department of the Brazilian Academy of Neurology.

The spectrum of neuropsychiatric phenomena observed in amyotrophic lateral sclerosis (ALS) is wide and not fully understood. Disorders of laughter and crying stand among the most common manifestations. The aim of this study is to report the results of an educational consensus organized by the Brazilian Academy of Neurology to evaluate the definitions, phenomenology, diagnosis, and management of the disorders of laughter and crying in ALS patients. Twelve members of the Brazilian Academy of Neurology - considered to be experts in the field - were recruited to answer 12 questions about the subject. After exchanging revisions, a first draft was prepared. A face-to-face meeting was held in Fortaleza, Brazil on 9.23.22 to discuss it. The revised version was subsequently emailed to all members of the ALS Scientific Department from the Brazilian Academy of Neurology and the final revised version submitted for publication. The prevalence of pseudobulbar affect/pathological laughter and crying (PBA/PLC) in ALS patients from 15 combined studies and 3906 patients was 27.4% (N = 1070), ranging from 11.4% to 71%. Bulbar onset is a risk factor but there are limited studies evaluating the differences in prevalence among the different motor neuron diseases subtypes, including patients with and without frontotemporal dementia. Antidepressants and a combination of dextromethorphan and quinidine (not available in Brazil) are possible therapeutic options. This group of panelists acknowledge the multiple gaps in the current literature and reinforces the need for further studies.

O espectro de fenômenos neuropsiquiátricos observados na ELA é amplo e não completamente entendido. Desordens do riso e do choro estão entre as manifestações mais comuns. O objetivo deste estudo é relatar os resultados de um Consenso organizado pela Academia Brasileira de Neurologia para avaliar definições, fenomenologia, diagnóstico, e manejo dos distúrbios do riso e do choro em pacientes com ELA. Doze membros da Academia Brasileira de Neurologia ­ considerados experts na área ­ foram recrutados para responder 12 questões na temática. Depois da verificação das revisões, um primeiro manuscrito foi preparado. Após, foi realizado um encontro presencial em Fortaleza, Brasil, em 23/09/2022, para discussão do conteúdo. A versão revisada foi posteriormente enviada por e-mail para todos os membros do Departamento Científico de DNM/ELA da Academia Brasileira de Neurologia e a versão final revisada foi submetida para publicação. A prevalência da síndrome pseudobulbar em pacientes com ELA em 15 estudos combinados com 3906 pacientes foi de 27,4% (n = 1070), variando entre 11,4% e 71%. Início bulbar é um fator de risco, mas há limitados estudos avaliando as diferenças em prevalência entre os diferentes subtipos de Doença do Neurônio Motor, incluindo pacientes com e sem Demência Frontotemporal. Antidepressivos e uma combinação de dextrometorfana e quinidina (indisponíveis no Brasil) são opções terapêuticas possíveis. Esse grupo de panelistas reconhece as múltiplas demandas não atendidas na literatura atual e reforça a necessidade de futuros estudos.

Average annual cost of Parkinson's disease in a Brazilian multiethnic population.

INTRODUCTION: With the current demographic transition, it is estimated that by 2050 Brazil will have a population of 90 million people aged 60 years or more, and in parallel Parkinson's disease (PD) will bring a considerable economic burden to our society. Brazil is considered multiracial due to its colonization, generating important social and regional inequalities. Knowing the costs of the PD may aid to improve local public policies. However, in Brazil, no estimates of these values have been made so far. OBJECTIVES: To evaluate direct, indirect, and out-of-pocket costs in Brazilian people with PD (PwP). METHODS: Categorical and numerical data were collected through a customized and standardized cost-related-questionnaire from 1055 PwP nationwide, from 10 tertiary movement disorders centers across all Brazilian regions. RESULTS: The estimated average annual cost of PwP was US$ 4020.48. Direct and indirect costs accounted for 63% and 36% of the total, respectively, and out-of-pocket costs were 49%. There were no evidence of differences in the total cost of PD across the regions of the country; however, differences were reported between the stages of the Hoehn and Yahr scale (H&Y). CONCLUSION: This data suggests a considerable burden of PD for Brazilian society in general, not only for the public health system, but mainly for those with PD.

Guidelines for Parkinson's disease treatment: consensus from the Movement Disorders Scientific Department of the Brazilian Academy of Neurology - motor symptoms.

The treatment of Parkinson's disease (PD) is challenging, especially since it is considered highly individualized. The Brazilian Academy of Neurology has recognized the need to disseminate knowledge about the management of PD treatment, adapting the best evidence to the Brazilian reality. Thus, the main published treatment guidelines were reviewed based on the recommendations of group from the Movement Disorders Scientific Department of the Brazilian Academy of Neurology.

[Civil construction workers and preventive measures against skin cancer: nursing contribution]. / Medidas de prevenção contra câncer de pele em trabalhadores da construção civil: contribuição da enfermagem.

Civil construction's workers are one of the most risk groups to the occupational cancer. The purpose was to identify these workers knowledge about skin cancer and describe protection/prevention measures adopted by them. This is a descriptive and qualitative nature research, developed with 50 workers of a great load building site firm at municipal district of Rio de Janeiro, Brazil. Data was collected through a form. From descriptive and statistical analysis, the results showed that the protection measures adopted by workers to avoid skin cancer are insufficient; moreover, they are not used in an aligned way with the literature. The most important necessary change relates to ife styles and access to information and knowledge about skin cancer. Thus, nursing's interventions along the Worker's Health stuff can contribute to the implementation of preventive measures against occupational cancer.

Induction of Ticlike Involuntary Movements in Rats by Striatotomy and Subsequent Neurochemical Sensitization.

OBJECTIVE: It has been proposed that Tourette syndrome is associated with dysfunction in widespread cortical areas and globus pallidus externus hyperactivity secondary to dopaminergic hyperactivity and serotonergic/dynorphinergic hypoactivity. The main objective of this study was to test this hypothesis by developing an animal model of Tourette syndrome via striatotomy, followed by administration of drugs that mimic the neurotransmitter environment, so as to induce globus pallidus externus hyperactivity. METHODS: Rats were assigned to 3 groups: stereotactic striatotomy (STT) and striatal sham -lesion (SHAM) groups, treated with anterior and posterior striatum procedures in both hemispheres, and a group of nonoperated animals (NAIVE). Postoperatively, all rodents were blindly administered 3 drug protocols: levodopa/benserazide; levodopa/benserazide/ergotamine/naloxone (MIX); and saline. The animals were filmed at the peak action of these drugs. The videos were evaluated by a single blinded researcher. RESULTS: Six types of involuntary movements (IMs) were observed: cephalic, trunk jerks, oromandibular, forepaw jerks, dystonic, and locomotive. The number of animals with IM and the mean number of IM after both levodopa/benserazide and MIX was significantly higher in the STT compared with the SHAM and NAIVE groups. In the SHAM and NAIVE, MIX was superior to levodopa/benserazide in the induction of IM. In the STT, MIX was superior to levodopa/benserazide in the induction of trunk jerks. Appendicular IM were more common after posterior than after anterior striatotomy. CONCLUSIONS: These results show that striatotomy, followed by administration of levodopa/benserazide alone or associated with ergotamine and naloxone, is efficacious in inducing IM, supporting the hypothesis that led to this study.

Prevalence of multiple sclerosis in Goiânia, Goiás, Brazil.

OBJECTIVE: Multiple sclerosis (MS) prevalence, in some cities in Brazil, was estimated and was found to range from 0.75 to 30.7/100,000. The reasons for such a large variation in rates of prevalence are not clear, but environment and genetics help to explain this phenomenon. METHODS: A cross-sectional study using three sources of case ascertainment to estimate the prevalence of MS in the city of Goiânia in December, 2015. RESULTS: A total of 318 MS patients was found after removing overlapping sources. The prevalence of MS was 22.4/100,000 population. CONCLUSION: Our study was the first in Goiás and the third in the midwest region, and we found a great increase in the prevalence of MS in the region. It is necessary to perform other studies using the same methodology for a more accurate evaluation of the true prevalence of MS in Brazil.

CHCHD2 mutational screening in Brazilian patients with familial Parkinson's disease.

Robust evidence on the involvement of genetic factors in the etiology of Parkinson's disease (PD) expands our knowledge about monogenic causes that contribute for this important neurodegenerative disorder. Mutations in the CHCHD2 gene have been linked to autosomal dominant forms of PD, although there is still lack of evidence for CHCHD2 variants leading to the disease in mixed populations as those from South America. To assess the contribution of CHCHD2 as a causal factor for familial PD in Brazil, one of the most heterogeneous populations in the world, we conducted the first molecular analysis of the CHCHD2 gene in a cohort of 122 index cases from Brazilian families with autosomal dominant forms of PD. Genomic DNA was isolated from peripheral blood and the 4 exons of the CHCHD2 gene, and their intron-exon boundaries were analyzed by bidirectional Sanger sequencing. No pathogenic or risk variants were found, suggesting that genetic variants of CHCHD2 are not a common cause of familial PD in Brazilian patients.

Music Therapy Reduces Radiotherapy-Induced Fatigue in Patients With Breast or Gynecological Cancer: A Randomized Trial.

PURPOSE: To investigate the influence of music therapy on the reduction of fatigue in women with breast or gynecological malignant neoplasia during radiotherapy, since it is one of the most frequent side effects of this type of treatment, and may interfere with self-esteem, social activities, and quality of life. EXPERIMENTAL DESIGN: Randomized controlled trial (control group [CG] and music therapy group [MTG]) to assess fatigue, quality of life, and symptoms of depression in women undergoing radiotherapy using the Functional Assessment of Cancer Therapy: Fatigue (FACT-F) version 4, Functional Assessment of Cancer Therapy-General (FACT-G) version 4, and Beck Depression Inventory in 3 separate times, namely, during the first week of radiotherapy, on the week of the intermediary phase, and during the last week of radiotherapy. Individual 30- to 40-minute sessions of music therapy with the presence of a trained music therapist were offered to participants. RESULTS: In this study, 164 women were randomized and 116 (63 CG and 53 MTG) were included in the analyses, with mean age of 52.90 years (CG) and 51.85 years (MTG). Participants in the MTG had an average of 10 music therapy sessions, totaling 509 sessions throughout the study. FACT-F results were significant regarding Trial Outcome Index ( P = .011), FACT-G ( P = .005), and FACT-F ( P = .001) for the MTG compared with the CG. CONCLUSIONS: Individual music therapy sessions may be effective to reduce fatigue related to cancer and symptoms of depression, as well as to improve quality of life for women with breast or gynecological cancer undergoing radiotherapy. Further well-designed research studies are needed to adequately determine the effects of music therapy on fatigue.

Conclusão: O teletrabalho mostrou- se uma importante modalidade de trabalho frente à pandemia de Covid-19. Apesar de ter sido uma ferramenta imprescindível para manutenção dos empregos e continuidade do funcionamento das empresas durante a pandemia, a saúde física e mental do trabalhador foi bastante afetada neste período.

Objective: To identify the implications of teleworking for the worker in the pandemic period of covid-19.Methods: This is an integrative literature review with searches in the Web of Science, Scopus, Medline via pubmed, Lilacs, Scielo and Cumulative Index to Nursing and Allied Health Literature databases, using the descriptors teleworking, pandemics, occupational health with boolean operator AND. The search was carried out in August 2022 and had the following inclusion criteria: texts in the format of scientific article with full text, published in the pandemic period (2020 - 2022), in English, Portuguese and Spanish. Duplicate articles, review research, and reflective articles were excluded. Results: We found 134 articles and after applying the criteria and evaluation of the textual corpus, we obtained a sample of 19 studies. The analysis unfolded in the creation of 03 categories, to mention: changes in lifestyle during remote work; implications related to mental health and isolation and implications related to the work process. Teleworking was a valuable tool because it provided business continuity and operation during the COVID-19 pandemic as the worker's physical and mental health was greatly affected. Conclusion: Teleworking proved to be an important way of working against the COVID-19 pandemic. Although it was an indispensable tool for maintaining jobs and continuing the functioning of companies during the pandemic, the physical and mental health of the worker was greatly affected in this period.

El teletrabajo era un instrumento valioso porque ofrecía continuidad y funcionamiento de las operaciones durante la pandemia del Covid-19, ya que la salud física y mental del trabajador se veía inmensamente afectada. Conclusión: el teletrabajo ha demostrado ser una importante modalidad de trabajo frente a la pandemia del Covid-19. Aunque fue un instrumento indispensable para mantener el empleo y continuar el funcionamiento de las empresas durante la pandemia, la salud física y mental del trabajador se ha visto muy afectada en este período.

Definitions, phenomenology, diagnosis, and management of the disorders of laughter and crying in amyotrophic lateral sclerosis (ALS): Consensus from ALS and Motor Neuron Disease Scientific Department of the Brazilian Academy of Neurology / Definições, fenomenologia, diagnóstico e manejo das desordens do riso e do choro em esclerose lateral amiotrófica (ELA): Consenso do Departamento Científico de ELA e Doença do Neurônio Motor da Academia Brasileira de Neurologia

Abstract The spectrum of neuropsychiatric phenomena observed in amyotrophic lateral sclerosis (ALS) is wide and not fully understood. Disorders of laughter and crying stand among the most common manifestations. The aim of this study is to report the results of an educational consensus organized by the Brazilian Academy of Neurology to evaluate the definitions, phenomenology, diagnosis, and management of the disorders of laughter and crying in ALS patients. Twelve members of the Brazilian Academy of Neurology - considered to be experts in the field - were recruited to answer 12 questions about the subject. After exchanging revisions, a first draft was prepared. A face-to-face meeting was held in Fortaleza, Brazil on 9.23.22 to discuss it. The revised version was subsequently emailed to all members of the ALS Scientific Department from the Brazilian Academy of Neurology and the final revised version submitted for publication. The prevalence of pseudobulbar affect/pathological laughter and crying (PBA/PLC) in ALS patients from 15 combined studies and 3906 patients was 27.4% (N = 1070), ranging from 11.4% to 71%. Bulbar onset is a risk factor but there are limited studies evaluating the differences in prevalence among the different motor neuron diseases subtypes, including patients with and without frontotemporal dementia. Antidepressants and a combination of dextromethorphan and quinidine (not available in Brazil) are possible therapeutic options. This group of panelists acknowledge the multiple gaps in the current literature and reinforces the need for further studies.

Resumo O espectro de fenômenos neuropsiquiátricos observados na ELA é amplo e não completamente entendido. Desordens do riso e do choro estão entre as manifestações mais comuns. O objetivo deste estudo é relatar os resultados de um Consenso organizado pela Academia Brasileira de Neurologia para avaliar definições, fenomenologia, diagnóstico, e manejo dos distúrbios do riso e do choro em pacientes com ELA. Doze membros da Academia Brasileira de Neurologia - considerados experts na área - foram recrutados para responder 12 questões na temática. Depois da verificação das revisões, um primeiro manuscrito foi preparado. Após, foi realizado um encontro presencial em Fortaleza, Brasil, em 23/09/2022, para discussão do conteúdo. A versão revisada foi posteriormente enviada por e-mail para todos os membros do Departamento Científico de DNM/ELA da Academia Brasileira de Neurologia e a versão final revisada foi submetida para publicação. A prevalência da síndrome pseudobulbar em pacientes com ELA em 15 estudos combinados com 3906 pacientes foi de 27,4% (n = 1070), variando entre 11,4% e 71%. Início bulbar é um fator de risco, mas há limitados estudos avaliando as diferenças em prevalência entre os diferentes subtipos de Doença do Neurônio Motor, incluindo pacientes com e sem Demência Frontotemporal. Antidepressivos e uma combinação de dextrometorfana e quinidina (indisponíveis no Brasil) são opções terapêuticas possíveis. Esse grupo de panelistas reconhece as múltiplas demandas não atendidas na literatura atual e reforça a necessidade de futuros estudos.
