OBJECTIVE To identify lifestyle-related, sociodemographic, and mental health characteristics of people with insomnia symptoms and people without insomnia during the pandemic. METHODS A case-control study was conducted with data collected by snowball sampling using an online questionnaire. From November 2020 to April 2021, 6,360 people with a mean age of 43.5 years (SD = 14.3) participated in the survey. For this study, we considered 158 cases of insomnia disorder and 476 controls (three controls per case) randomly selected from the participants without sleep problems. RESULTS The results of the comparative analysis between cases and controls showed that sleeping less than six hours daily (OR = 3.89; 95%CI 2.50–6.05), feeling sadness frequently (OR = 2.95; 95%CI 1.69–5.17), residing in metropolitan areas (OR = 1.71; 95%CI 1.04–2.84), being 40 years or older (OR = 1.93; 95%CI 1.22–3.06), and the interaction between occupation and poorer education (OR = 2.12; 95%CI 1.22–3.69) were predictors for symptoms of insomnia disorder during the pandemic. CONCLUSIONS In addition to confirming the hypothesis that mental health problems are associated with insomnia symptoms, the results point to insomnia as an important outcome for studies on the effects of unemployment, vulnerability and low education of the population, especially in large cities, highlighting that the effects of the crisis on health and the economy are extremely unequally distributed. RESUMO OBJETIVO Identificar características relacionadas ao estilo de vida, sociodemográficas e saúde mental de pessoas com sintomas de insônia e pessoas sem insônia durante a pandemia. MÉTODOS A partir de dados coletados por amostragem em bola de neve, por meio de um questionário online foi realizado um estudo caso-controle. Durante o período de novembro de 2020 a abril de 2021, 6.360 pessoas com idade média de 43,5 anos (DP = 14,3) participaram da pesquisa. No presente estudo, foram considerados 158 casos de transtorno de insônia e 476 controles (três controles por caso) selecionados aleatoriamente dentre os participantes sem problemas de sono. RESULTADOS Os resultados da análise comparativa entre casos e controles mostraram que dormir menos de seis horas diárias (OR = 3,89; IC95% 2,50–6,05), sentir tristeza frequentemente (OR = 2,95; IC95% 1,69–5,17), residir em metrópoles (OR = 1,71; IC95% 1,04–2,84), estar com 40 anos ou mais (OR = 1,93; IC95% 1,22–3,06) e a interação entre ocupação e escolaridade mais precária (OR = 2,12; IC95% 1,22–3,69) foram fatores preditores para sintomas de transtorno de insônia durante a pandemia. CONCLUSÕES Além da confirmação da hipótese de que problemas de saúde mental estão associados a sintomas de insônia, os resultados apontam para a insônia como um desfecho importante para estudos sobre efeitos do desemprego, vulnerabilidade e baixa escolaridade da população, sobretudo nas grandes metrópoles, ressaltando que os efeitos da crise sobre a saúde e a economia são distribuídos de forma extremamente desiguais.

Study objectivesTo evaluate the impact of COVID-19 pandemic on sleep, anxiety, and Burnout in healthcare professionals.MethodsA survey was distributed using social media and organizational emails to Brazilian active healthcare professionals during the COVID-19 outbreak. We explored potential associated factors including age, gender, occupation, workplace, work hours, income, previous infection with COVID-19, recent/current contact with COVID-19 patients, regional number of incident deaths due to COVID-19, anxiety, and burnout. We evaluated new-onset or previous insomnia worsening (primary outcome), sleep quality, and duration (secondary outcomes).ResultsA total of 4,384 health professionals from all regions of the country were included in the analysis (mean age: 44±12 years, 76% females, 53.8% physicians). Overall, 55.7% were assisting patients with COVID-19, and 9.2% had a previous COVID-19 infection. New-onset insomnia symptoms or previous insomnia worsening occurred in 41.4% of respondents in parallel to 13% (n=572) new pharmacological treatments for insomnia. Prevalent anxiety and burnout during the pandemic were observed in 44.2% and 21% of participants, respectively. Multivariate analyses showed that females (OR:1.756; 95% CI 1.487-2.075), weight change (decrease: OR:1.852; 95% CI 1.531-2.240; increase: OR:1.542; 95% CI 1.323-1.799), prevalent anxiety(OR:3.209; 95% CI 2.796-3.684), new-onset burnout (OR:1.986; 95% CI 1.677-2.352), family income reduction >30% (OR:1.366; 95% CI 1.140-1.636) and assisting patients with COVID-19 (OR:1.293; 95% CI 1.104-1.514) were independently associated with new-onset or worsening of previous insomnia.ConclusionsWe observed a huge burden of insomnia in healthcare professionals during the COVID-19 pandemic. In this scenario, dedicated approaches for sleep health are highly desirable.Statement of SignificanceConsidering the stressful routine and risk of infection by COVID-19 among healthcare professionals, it is conceivable that sleep disturbances are significantly impaired during the pandemic. This nationwide survey conducted in Brazil found that 41.4% developed new-onset or worsening of previous insomnia symptoms. Moreover, 572 (13%) of respondents initiated pharmacological treatments for insomnia. Females, weight change, anxiety, Burnout development, family income reduction >30%, and recent/current care of patients with COVID-19 were independently associated with the development of insomnia or exacerbated previous insomnia symptoms. Considering the potential impact of insomnia on work performance/healthcare decisions as well as the potential long-term dependence of pharmacological treatments for insomnia, this study underscores the need for dedicated sleep and mental health programs for healthcare professionals.

O Consenso em síndrome das pernas inquietas contou com a participação de neurologistas de vários estados brasileiros, os quais incansavelmente revisaram a literatura dos últimos anos em busca de evidências, tanto no que se refere ao diagnóstico como ao tratamento, de acordo com a Classificação do Centro de Oxford para Medicina Baseada em Evidências. The Consensus on restless legs syndrome is an effort of neurologists from several Brazilian states, which tirelessly reviewed the literature of recent years in search of evidence, both in regard to diagnosis and treatment, according to the Oxford Centre for Evidence-based Medicine.

Este artigo relata as conclusões da reunião de consenso com médicos especialistas sobre diagnóstico de narcolepsia baseada na revisão dos artigos sobre narcolepsia listados no Medline entre 1980 e 2010. A narcolepsia é uma doença crônica de início entre a primeira e segunda décadas de vida do indivíduo. Os sintomas essenciais são cataplexia e sonolência excessiva. A cataplexia é definida como episódios súbitos, recorrentes e reversíveis de fraqueza da musculatura esquelética desencadeados por situações de conteúdo emocional. Os sintomas acessórios são alucinações hipnagógicas, paralisia do sono e sono fragmentado. Critérios de diagnóstico clínico de acordo com a Classificação Internacional dos Transtornos do Sono são de sonolência excessiva e cataplexia. Recomenda-se a realização de polissonografia seguida do teste de latência múltipla do sono em um laboratório de sono para confirmação e diagnóstico de comorbidades. Quando não houver cataplexia, deve haver duas ou mais sonecas com sono REM no teste de latência múltipla do sono. Tipagem HLA-DQB1*0602 positiva com níveis de hipocretina-1 abaixo de 110pg/mL devem estar presentes para o diagnóstico de narcolepsia sem cataplexia e sem sonecas com sono REM. This manuscript contains the conclusion of the consensus meeting on the diagnosis of narcolepsy based on the review of Medline publications between 1980-2010. Narcolepsy is a chronic disorder with age at onset between the first and second decade of life. Essential narcolepsy symptoms are cataplexy and excessive sleepiness. Cataplexy is defined as sudden, recurrent and reversible attacks of muscle weakness triggered by emotions. Accessory narcolepsy symptoms are hypnagogic hallucinations, sleep paralysis and nocturnal fragmented sleep. The clinical diagnosis according to the International Classification of Sleep Disorders is the presence of excessive sleepiness and cataplexy. A full in-lab polysomnography followed by a multiple sleep latency test is recommended for the confirmation of the diagnosis and co-morbidities. The presence of two sleep-onset REM period naps in the multiple sleep latency test is diagnostic for cataplexy-free narcolepsy. A positive HLA-DQB1*0602 with lower than 110pg/mL level of hypocretin-1 in the cerebrospinal fluid is required for the final diagnosis of cataplexy- and sleep-onset REM period -free narcolepsy.
