The impact of the COVID-19 pandemic on sleep disorders among Nursing professionals / O impacto da pandemia de COVID-19 nas alterações do sono de profissionais de enfermagem / Impacto de la pandemia de COVID-19 en los trastornos del sueño de profesionales de enfermería

Abstract Objective: to analyze the factors related to sleep disorders reported by Nursing professionals during the COVID-19 pandemic. Method: this is a cross-sectional and analytical study conducted with Nursing professionals from all Brazilian regions. Sociodemographic data, working conditions and questions about sleep disorders were collected. The Poisson regression model with repeated measures was used to estimate the Relative Risk. Results: 572 answers were analyzed, which revealed that non-ideal sleep duration, poor sleep quality and dreams about the work environment were predominant during the pandemic, with 75.2%, 67.1% and 66.8% respectively; as well as complaints of difficulty sleeping, daytime sleepiness and non-restorative sleep during the pandemic were reported by 523 (91.4%), 440 (76.9%) and 419 (73.2%) of the Nursing professionals, respectively. The relative risk of having such sleep disorders during the pandemic was significant for all variables and categories studied. Conclusion: non-ideal sleep duration, poor sleep quality, dreams about the work environment, complaints regarding difficulty sleeping, daytime sleepiness and non-restorative sleep were the predominant sleep disorders among Nursing professionals during the pandemic. Such findings point to possible consequences on health, as well as on the quality of the work performed.

Does smoking impair sleep hygiene? / O tabagismo prejudica a higiene do sono?

ABSTRACT Background: Sleep architecture and sleep hygiene might be disrupted by several pathogenetic mechanisms, and the effect of smoking has not been evaluated. Objective: To investigate the effect of smoking on sleep hygiene behaviors that might be associated with the deterioration of quality-of-life (QoL) parameters. Methods: In a prospective cross-sectional study, smokers (n=114) and nonsmokers (n=119) were included. The Pittsburgh Sleep Quality İndex (PSQI), the Epworth Daytime Sleepiness Scale (ESS), the Sleep Hygiene Index (SHI), and the Short Form-36 quality of life scale (SF-36) were applied. Results: We found that none of the components, as well as the PSQI total score were affected in smokers compared with the nonsmoker controls (65.5% of smokers had poor sleep compared to 62.5% of nonsmokers). Although smokers tend to get out of bed at different times from day to day and do important work before bedtime (components of the SHI) more often than non-smokers, no significant differences were detected between groups in any component and SHI total score (27.91±6.72 for smokers and 29.23±8.0 for non-smokers). ESS, depression and anxiety symptoms, and SHI scores in smokers with poor sleep quality were significantly different compared with smokers that had normal sleep quality. Both PSQI and SHI scores were inversely associated with QoL parameters. Conclusions: Our results suggest that smoking by itself is not associated with poor sleep hygiene or sleep quality. It can be concluded that worse SHI and quality of sleep negatively affect QoL, depression, and anxiety in smokers.

RESUMO Antecedentes: A arquitetura e a higiene do sono podem ser interrompidas por vários mecanismos patogenéticos, e o efeito do tabagismo ainda não foi avaliado. Objetivo: Investigar o efeito do tabagismo nos comportamentos de higiene do sono que podem estar associados à deterioração dos parâmetros de qualidade de vida (QV). Métodos: Em um estudo transversal prospectivo, foram incluídos fumantes (n=114) e não fumantes (n=119). Foram aplicados o índice de qualidade do sono de Pittsburgh (Pittsburgh Sleep Quality İndex - PSQI), a escala de sonolência diurna de Epworth (ESS), o índice de higiene do sono (Sleep Hygiene Index - SHI) e a escala de qualidade de vida Short Form-36 (SF-36). Resultados: Descobrimos que nenhum dos componentes, assim como o escore total do PSQI, foram afetados em fumantes em comparação com os controles não fumantes (65,5% dos fumantes dormiam mal em comparação com 62,5% dos não fumantes). Embora os fumantes tendam a sair da cama em horários diferentes do dia a dia e fazer trabalhos importantes antes de dormir (componentes do SHI) com mais frequência do que os não fumantes, não foram detectadas diferenças significativas entre os grupos em qualquer componente e pontuação total do SHI (27,91±6,72 para fumantes e 29,23±8,0 para não fumantes). A ESS, os sintomas de depressão e ansiedade e os escores SHI em fumantes com má qualidade de sono foram significativamente diferentes em comparação com fumantes com qualidade de sono normal. Os escores do PSQI e SHI foram inversamente associados aos parâmetros de QV. Conclusões: Nossos resultados sugerem que o tabagismo por si só não está associado à má higiene ou qualidade do sono. Pode-se concluir que o pior SHI e a qualidade do sono afetam negativamente a QV, a depressão e a ansiedade em fumantes.

At the crossroads of epilepsy and sleep: some issues / Na encruzilhada da epilepsia e do sono: algumas questões

There is a close association between sleep and epilepsy, and this literature review aims to raise issues regarding sleep time control, circadian and ultradian rhythms, epilepsy and its interaction with sleep and circadian rhythm, epilepsy and sleep disorders, and finally epilepsy management and medications. It is mentioned that sleep may provide a hypersynchronous state, as occurs in non-rapid eye movement sleep (NREM), and hyperexcitability, in cyclic alternating pattern (CAP), allowing more frequent interictal epileptiform abnormalities and seizures. In some epilepsy syndromes, seizures occur broadly / or entirely during sleep or on awakening, mainly in childhood, and maybe exacerbated in adults during the sleep or sleep-deprived, and there are the so-called Sleep-related epilepsies that are divided as sleep-associated, sleep-accentuated and arousal/awakening related. Sleep quality may be reduced in patients with epilepsy also due to nocturnal seizures or concomitant sleep disorders. Sleep disorders are common in patients with epilepsy and treatment of them mainly sleep-disordered breathing may improve seizure control. Besides, some parasomnias may mimic seizures, and also they can adversely affect the quality and quantity of sleep whereas antiepileptic therapy can have a negative or positive effect on sleep. Nocturnal epileptic seizures may be challenging to discern from parasomnias, in particular NREM parasomnias such as night terrors, sleepwalking and confusional arousals.

Há uma estreita associação entre sono e epilepsia, e esta revisão de literatura tem como objetivo levantar questões relacionadas ao controle do tempo do sono, ritmos circadianos e ultradianos, epilepsia e sua interação com sono e ritmo circadiano, epilepsia e transtornos do sono e, finalmente, o tratamento e medicamentos para epilepsia. Menciona-se que o sono pode proporcionar um estado hipersincrônico, como ocorre no sono "non-rapid eye movement" (NREM), e hiperexcitabilidade, no "cyclic alternating pattern" (CAP), permitindo anormalidades epileptiformes interictais e crises epilépticas mais frequentes. Em algumas síndromes epilépticas, as crises ocorrem ampla / ou inteiramente durante o sono ou despertar, principalmente na infância, e podem ser exacerbadas em adultos durante o sono ou privação de sono, e as chamadas epilepsias relacionadas ao sono se dividem em sono associadas, sono acentuadas e relacionadas com o despertar. A qualidade do sono pode ser reduzida em pacientes com epilepsia também devido a crises epilépticas noturnas ou transtornos do sono concomitantes. Esses são comuns em pacientes com epilepsia e o seu tratamento, principalmente dos transtornos respiratórios do sono, pode melhorar o controle das crises epilépticas. Além disso, algumas parassonias podem mimetizar crises epilépticas, e também elas podem afetar adversamente a qualidade e a quantidade do sono, enquanto a terapia antiepiléptica pode ter um efeito negativo ou positivo sobre o sono. Pode ser difícil discernir as crises epilépticas noturnas das parassonias, em particular das parassonias NREM, como terrores noturnos, crises de sonambulismo e despertares confusionais.

Parkinson's disease and periodic limb movement in sleep / Doença de Parkinson e movimentos periódicos dos membros durante o sono

Parkinson's disease is a neurodegenerative disease understood as a complex syndrome with motor and non-motor symptoms, including sleep-related conditions, such as periodic limb movements in sleep (PLMS). This paper presents issues regarding Parkinson's disease, motor and non-motor symptoms, sleep physiology, and PLMS. In conclusion, both conditions seem to be correlated through impairment of the dopaminergic system.

A doença de Parkinson é uma doença neurodegenerativa entendida como uma síndrome complexa com sintomas motores e não motores, incluindo condições relacionadas ao sono, como movimentos periódicos dos membros durante o sono (MPMS). Este artigo apresenta questões relacionadas à doença de Parkinson, sintomas motores e não motores, fisiologia do sono e MPMS. Em conclusão, ambas as condições parecem estar correlacionadas por comprometimento do sistema dopaminérgico.

El Síndrome de Treacher Collins (STC) es una enfermedad congénita del desarrollo craneofacial, siendo una complicación frecuente la obstrucción de la vía aérea. Objetivo: Describir clínicamente tres casos de STC y sus hallazgos polisomnográficos. Diseño: Estudio observacional, descriptivo y retrospectivo. Revisión de fichas clínicas y polisomnografías (PSG). Resultados: Se incluyeron tres pacientes con STC, de 1, 17 y 20 años, dos hombres. Todos presentaron malformaciones faciales compatibles con el STC. El paciente menor tuvo apneas desde el nacimiento. En las PSG, todos presentaron eficiencia del sueño disminuida e índice de microdespertares aumentado. Solo un paciente tuvo diagnóstico de Síndrome de Apnea/Hipoapnea Obstructiva del Sueño (SAHOS) severo. Conclusiones: Aún cuando las anomalías craneofaciales no difirieron entre los pacientes, hubo sólo un caso de SAHOS severo. Las otras alteraciones descritas en la PSG afectan la calidad de vida, siendo relevante la búsqueda activa de trastornos respiratorios del sueño en estos pacientes.

Treacher Collins Syndrome (STC) is a congenital craniofacial disorder, being the airway obstruction a frequent complication. Objective: To describe clinical and polysomnographic findings of three cases with STC. Methods: An observational, descriptive and retrospective study. Review of clinical records and nocturnal polysomnography was carried out. Results: Three patients with STC were included of 1, 17 and 20 years old, two were males. All of them with facial malformations compatible with STC. Only the youngest presented apneas since birth. All patients had decreased sleep efficiency and increased arousal index. Only one patient presented with severe Obstructive Sleep Apnea Syndrome (OSAS).

Trastorno de hipoventilación central del sueño en pediatría: causas poco frecuentes / Central hypoventilation disorders sleep-related in pediatrics: unusual causes

Congenital central hypoventilation syndrome (CCHS) and rapid-onset obesity syndrome with hypothalamic dysfunction, hypoventilation, and autonomic dysregulation (ROHHAD) are rare causes of hypoventilation during sleep in the pediatric population. This group of disorders are characterized by the absence or decrease in the automatic control of ventilation, decreased sensitivity of chemoreceptors to CO2, causing hypoventilation during sleep and even in wakefulness, in the most severe cases. For these reasons it is important to diagnose and treat them promptly. The objective of this review is to provide current and complete literature, to be able to identify, treat and refer this group of children early, and thus reduce the complications and/or associated comorbidities in the short and long term, improving their quality of life.

El síndrome de hipoventilación central congénita (CCHS) y síndrome de obesidad de inicio rápido con disfunción hipotalámica, hipoventilación y desregulación autonómica (ROHHAD), son causas poco comunes de hipoventilación durante el sueño en la población pediátrica. Este grupo de trastornos se caracterizan por ausencia o disminución en el control automático de la ventilación, sensibilidad disminuida de los quimioreceptores al CO2, provocando hipoventilación durante el sueño e incluso en vigilia, en los casos más severos. Por estas razones es importante diagnosticarlos y tratarlos oportunamente. El objetivo de esta revisión es proporcionar literatura actual y completa, para poder identificar, tratar y referir a éste grupo de niños tempranamente, y así disminuir las complicaciones y/o comorbilidades asociadas a corto y largo plazo, mejorando su calidad de vida.

Constructs of poor sleep quality in adolescents: associated factors / Os construtos de baixa qualidade de sono em adolescentes: fatores associados / Constructos de calidad deficiente del sueño en adolescentes: factores asociados

This study aims to evaluate factors associated with sleep quality (overall and by domains) in adolescents. A cross-sectional study. This study was conducted with 1,296 first-year high school students from public schools in the Northern Region of the State of Pernambuco, Brazil. Demographic, socioeconomic, and behavioral data were obtained with a questionnaire. Sleep quality was measured using the Pittsburgh Sleep Quality Index (PSQI) Body mass index (BMI) was calculated based on the ratio of weight and height squared. Multilevel linear and logistic regressions evaluated factors associated with sleep quality. We observed 53% of adolescents reported poor sleep quality. Adolescents at higher risk of clinical depression were 3.45 times more likely to have poor sleep quality (95%CI: 2.04; 5.81), and each additional unit in the social anxiety score presented 1.03 (95%CI: 1.01; 1.05) higher odds of adolescents having poor sleep quality. Adolescents with depressive symptoms had higher sleep latency, greater sleep disturbance, and greater daytime sleep dysfunction. Social anxiety was associated with sleep latency, sleep disturbance, and daytime sleep dysfunction. Higher risk of clinical depression was associated with all domains related to sleep quality. Negative health perception was associated with sleep disturbance, and physical inactivity was associated with daytime sleep dysfunction. Social anxiety and especially higher risk of clinical depression were determinants of poor sleep quality. Changes in sleep latency, sleep disturbance and daytime sleep dysfunction seems to be relevant to poor sleep quality.

O estudo buscou avaliar os fatores associados à qualidade do sono (global e por domínios) entre adolescentes. Foi realizado um estudo transversal com 1.296 estudantes de primeiro ano do ensino médio em escolas públicas na Região Norte do Estado de Pernambuco, Brasil. Foram obtidos dados demográficos, socioeconômicos e comportamentais através de um questionário. A qualidade do sono foi medida com o Pittsburgh Sleep Quality Index (PSQI). O índice de massa corporal (IMC) foi calculado como peso dividido por altura ao quadrado. Os fatores associados à qualidade do sono foram avaliados através da regressão linear multinível e logística. Observamos que 53% dos adolescentes relatavam baixa qualidade de sono. Os adolescentes com risco maior de depressão clínica apresentaram 3,45 vezes maior probabilidade de apresentar baixa qualidade de sono (IC95%: 2,04; 5,81), e cada unidade adicional na escala de ansiedade social apresentou 1,03 vezes maiores chances (IC95%: 1,01; 1,05) de baixa qualidade de sono. Os adolescentes com sintomas depressivos mostraram maior latência do sono, maior transtorno do sono e maior disfunção diurna do sono. A ansiedade social mostrou associação com latência do sono, transtorno do sono e disfunção diurna do sono. O risco maior de depressão esteve associado a todos os domínios relacionados à qualidade. Autoavaliação de saúde negativa esteve associada ao transtorno do sono, e inatividade física esteve associada à disfunção diurna do sono. Ansiedade social, e principalmente risco maior de depressão clínica, foram determinantes na baixa qualidade do sono. Mudanças na latência do sono, transtorno do sono e disfunção diurna do sono parecem ser relevantes para a baixa qualidade do sono.

El objetivo de este estudio fue evaluar factores asociados con la calidad del sueño (general y por ámbitos) en adolescentes. Se realizó un estudio transversal con 1.296 estudiantes del primer año de escuela secundaria, procedentes de escuelas públicas en la Región Norte del Estado de Pernambuco, Brasil. Se obtuvieron datos demográficos, socioeconómicos y comportamentales, a través de un cuestionario. La calidad del sueño se midió usando el Pittsburgh Sleep Quality Index (PSQI). El índice de masa corporal (IMC) se calculó de la ratio de peso y altura al cuadrado. Las regresiones logísticas y lineales multinivel evaluaron factores asociados con calidad del sueño deficiente. Observamos que un 53% de los adolescentes informaron de una calidad de sueño deficiente. Los adolescentes con mayor riesgo de depresión clínica fueron 3,45 veces más propensos a tener una calidad de sueño deficiente (95%CI: 2,04; 5,81), y cada unidad adicional en la puntuación de ansiedad social presentaba 1,03 (95%CI: 1,01; 1,05) mayores posibilidades de adolescentes sufriendo por calidad de sueño deficiente. Los adolescentes con síntomas depresivos presentaban mayor latencia de sueño, mayores perturbaciones en el sueño, y mayor disfunción durante el día de sueño. La ansiedad social estuvo asociada con la latencia de sueño, perturbaciones de sueño y disfunción del sueño durante el día. Un mayor riesgo de depresión clínica estuvo asociado con todos los ámbitos relacionados con calidad del sueño. Una percepción negativa de salud respecto a la perturbación de sueño e inactividad física estuvo asociada con un sueño deficiente durante el día. La ansiedad social y, especialmente, un mayor riesgo de depresión clínica fueron determinantes en una escasa calidad de sueño. Los cambios en la latencia del sueño, trastornos del sueño y disfunción del sueño durante el día parecieron relevantes para la deficiente calidad del sueño.

Correlation between preoperative sleep disorders and postoperative delayed neurocognitive recovery in elderly patients / 中南大学学报(医学版)

OBJECTIVES@#Perioperative neurocognitive disorders (PND) is one of the important factors affecting the recovery of the elderly after surgery, and sleep disorders are also one of the common diseases of the elderly. Previous studies have shown that the quality of postoperative sleep may be factor affecting postoperative cognitive function, but there are few studies on the relationship between preoperative sleep disorders and postoperative cognitive dysfunction. This study aims to explore the relationship between preoperative sleep disorders and postoperative delayed neurocognitive recovery in elderly patients, and provide references for improving the prognosis and quality of life of patients.@*METHODS@#This study was porformed as a prospective cohort study. Elderly patients (age≥65 years old) underwent elective non-cardiac surgery at Xiangya Hospital of Central South University from October 2019 to January 2020 were selected and interviewed 1 day before the operation. The Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment Scale (MoCA) were used to assess the patient's baseline cognitive status. Patients with preoperative MMSE scores of less than 24 points were excluded. For patients meeting the criteria of inclusion, Pittsburgh Sleep Quality Index (PSQI) scale was used to evaluate the patients, and the patients were divided into a sleep disorder group and a non-sleep disorder group according to the score. General data of patients were collected and intraoperative data were recorded, such as duration of surgery, anesthetic time, surgical site, intraoperative fluid input, intraoperative blood product input, intraoperative blood loss and drug use. On consecutive 5 days after surgery, Numerical Rating Scale (NRS) was used to evaluate the sleep of the previous night and the pain of the day, which were recorded as sleep NRS score and pain NRS score; Confusion Assessment Method for ICU (CAM-ICU) scale and Confusion Assessment Method (CAM) scale were used to assess the occurrence of delirium. On the 7th day after the operation, the MMSE and MoCA scales were used to evaluate cognitive function of patients. We compared the incidence of postoperative complications, the number of deaths, the number of unplanned ICU patients, the number of unplanned secondary operations, etc between the 2 groups. The baseline and prognosis of the 2 groups of patients were analyzed by univariate and multivariate logistics to analyze their correlation.@*RESULTS@#A total of 105 patients were collected in this study, including 32 patients in the sleep disorder group and 73 patients in the non-sleep disorder group. The general information of the 2 groups, such as age, gender, body mass index, and surgery site, were not statistically significant (all @*CONCLUSIONS@#Preoperative sleep disorders can increase the risk of delayed neurocognitive function recovery in elderly patients. Active treatment of preoperative sleep disorders may improve perioperative neurocognitive function in elderly patients.

Depression is a major determinant of sleep abnormalities in patients with epilepsy / A depressão é um dos principais determinantes das anormalidades do sono em pacientes com epilepsia

ABSTRACT Introduction: We aimed to identify sleep disorders in patients with epilepsy and compare this group with a healthy population. We also analyzed the features of sleep disorders in patients with epilepsy to demonstrate the effect of seizures and seizure types on sleep. Methods: Our study assessed 43 patients with epilepsy and 53 age- and gender-matched healthy controls. The demographic and clinical data of all participants were recorded. The Epworth Sleepiness Scale, Pittsburgh Sleep Quality Index (PSQI), International Restless Legs Syndrome Study Group Rating Scale, Berlin Questionnaire, and Beck Depression Inventory (BDI) were administered to all study subjects. The interview used to evaluate insomnia is based on the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition - DSM-5 diagnostic criteria. Results: Twenty-four patients (55.8%) and 26 controls (49.1%) are women. The mean age of patients and controls was 34.2±11.37 (16-71) and 34.6±11.28 (16-77), respectively. Patients with epilepsy had depression more often than controls, a result that was statistically significant (p<0.0001). We found no statistically significant difference between sleep parameters of patients and controls with normal BDI scores (p>0.05). Patients with depression had worse results on the Berlin Questionnaire and PSQI total score, with statistical significance (p=0.002). Nocturnal seizures, seizure type, and drug treatment had no effect on sleep (p>0.05). Conclusion: We concluded that depression rather than epilepsy negatively affects sleep, suggesting that all patients should be asked about their mood and sleep complaints.

RESUMO Introdução: O objetivo deste estudo foi identificar distúrbios do sono em pacientes com epilepsia e compará-los com uma população saudável. Também foram examinadas as características dos distúrbios do sono em pacientes com epilepsia para demonstrar o efeito e os tipos de convulsões no sono. Métodos: O estudo consistiu em 43 pacientes com epilepsia e 53 controles saudáveis ​​pareados por idade e sexo. Os dados demográficos e clínicos de todos os participantes foram registrados. Todos os participantes do estudo receberam a Escala de Sonolência de Epworth, o Índice de Qualidade do Sono de Pittsburgh (Pittsburch Sleep QUality Index - PSQI), o Questionário do Grupo Internacional de Estudos das Pernas Inquietas, o Questionário de Berlim e o Inventário de Depressão de Beck. A entrevista usada para avaliar a insônia é baseada nos critérios do DSM-V. Resultados: Vinte e quatro pacientes (55,8%) são do sexo feminino e vinte e seis do grupo controle (49,1%) são do sexo feminino. A média de idade dos pacientes e do grupo controle é de 34,2±11,37 (16-71) e 34,6±11,28 (16-77), respectivamente. Pacientes com epilepsia sofrem mais de depressão do que os controles e esse resultado é estatisticamente significativo (p<0,0001). Não houve diferença estatisticamente significativa entre os parâmetros do sono dos pacientes e dos controles que apresentaram escores de Beck normais (p>0,05). Pacientes com depressão apresentam resultados piores no escore total do PSQI de Berlim, o que é estatisticamente significativo (p=0,002). As convulsões noturnas, o tipo de convulsão e o tratamento medicamentoso não afetaram o sono (p>0,05). Conclusão: Determinamos que a depressão, e não a epilepsia, afeta negativamente o sono dos pacientes, sugerindo que todos os pacientes devem ser questionados sobre seu humor e queixas de sono.

Restless legs syndrome/Willis-Ekbom disease in multiple sclerosis: a contributing factor for anxiety, disability, sleep disorder, and quality of life / Síndrome de las piernas inquietas/enfermedad de Willis-Ekbom en la esclerosis múltiple: un factor que contribuye a la ansiedad, la discapacidad, los trastornos del sueño y la calidad de vida

ABSTRACT Background: Restless legs syndrome (RLS) is one of the most common and burdensome sleep disorders in the course of multiple sclerosis (MS). Objective: To evaluate common MS-related symptoms and consequences between groups with and without RLS and further assess the association of quality of life determinants with RLS symptom severity. Methods: According to their RLS status, 46 relapsing-remitting MS patients were divided into MS-RLS+ (n=19) and MS-RLS- groups (n=27). Specific questionnaires were administered to assess the patients' health-related quality of life (HRQoL), fatigue levels, sleep quality, daily sleepiness, anxiety, and depression symptoms. Functional capacity was examined using the Expanded Disability Status Scale (EDSS). Results: The prevalence of RLS was 41.3%. Compared to the MS-RLS- group, those with RLS had higher EDSS scores, more cranial and spinal lesions, longer disease duration, and were older. In the MS-RLS+ group, symptom severity scores were positively correlated with higher anxiety and poorer sleep quality. The symptom severity score was negatively correlated with mental HRQoL and pain scores. Conclusion: In conclusion, the findings of the current study indicate the negative impact of RLS on functional capacity, anxiety, sleep quality, and mental HRQoL of MS patients. Further studies using more accurate diagnostic strategies for identifying RLS and other sleep disorders are necessary to clarify the association of MS with RLS and explore relevant clinical implications.

RESUMEN Antecedentes: El síndrome de piernas inquietas (SPI) es uno de los trastornos del sueño más comunes y onerosos en el curso de la esclerosis múltiple (EM). Objetivo: El objetivo de este estudio fue evaluar los síntomas y las consecuencias comunes asociados con la EM entre los grupos con y sin SPI y evaluar aún más la asociación de los determinantes de la calidad de vida con la gravedad de los síntomas del SPI. Métodos: De acuerdo con su estado de SPI, 46 pacientes con EM recurrente-remitente se dividieron en los grupos EM-SPI+ (n=19) y EM-SPI- (n=27). Se utilizaron cuestionarios específicos para evaluar la calidad de vida relacionada con la salud (CVRS), los niveles de fatiga, la calidad del sueño, la somnolencia diaria, la ansiedad y los síntomas de depresión de los pacientes. La capacidad funcional se examinó mediante la escala ampliada del estado de discapacidad (Expanded Disability Status Scale — EDSS). Resultados: La prevalencia de SPI fue del 41,3%. Em comparación com el grupo EM-SPI-, aquellos com SPI tenían púntuaciones más altas em la EDSS, más lesiones craneales y espinales, mayor duración de la enfermedad y eran mayores. Los puntajes de gravedad de los síntomas em el grupo EM-SPI+ se correlacionaron positivamente con una mayor ansiedad y una peor calidad del sueño. Se observaron correlaciones negativas entre la puntuación de gravedad de los síntomas y la CVRS mental y los puntajes de dolor. Conclusiones: En conclusión, el estudio actual indica el impacto negativo del SPI en la discapacidad funcional, la ansiedad, la calidad del sueño y la CVRS mental de los pacientes con EM. Se necesitan más estudios que utilicen estrategias de diagnóstico más precisas para identificar el SPI y otros trastornos del sueño para aclarar la asociación de la EM con el SPI y para explorar implicaciones clínicas relevantes.

Sleep and immunity in times of COVID-19

SUMMARY BACKGROUND Analyze how the COVID-19 (SARS-CoV-2) pandemic and its social restriction measures affect sleep quality and the immunological system. METHODS An integrative bibliographical review was carried out using scientific articles from the last five years, from the PUBMED databases, with the descriptors: Sleep; Quarantine; COVID-19; Immunity; Mental Health. Besides the books "Oxford textbook of sleep disorders", "Cellular and molecular immunology", and "Treaty of Infectology". RESULTS Sleep affects immunity. This happens through the regulation of immunological markers and their cells. Therefore, the COVID-19 pandemic can promote sleep disturbances and harm the immune system function. CONCLUSION Sleep exercises a direct influence on immunity maintenance and immunological response. Circadian rhythm alterations, associated with the psychological problems imposed by the COVID-19 pandemic compromise the quality of sleep and, for that reason, the immune system.

RESUMO OBJETIVOS Analisar como a pandemia de COVID-19 (Sars-CoV-2) e as medidas de restrição social afetam a qualidade do sono e o sistema imunológico. MÉTODOS Fez-se uma revisão bibliográfica integrativa usando-se artigos científicos dos últimos cinco anos, das bases de dados PubMed, com os descritores: Sono; Quarentena; COVID-19; Imunidade; Saúde mental. Além dos livros Oxford textbook of sleep disorders, Cellular and molecular immunology e Tratado de infectologia. RESULTADOS O sono afeta a imunidade. Isso se dá por meio da regulação de marcadores imunológicos e suas células. Dessa forma, a pandemia de COVID-19 pode corroborar distúrbios de sono e prejudicar o funcionamento do sistema imune. CONCLUSÃO O sono exerce influência direta na manutenção da imunidade e da resposta imunológica. A alteração do ritmo circadiano, atrelada aos problemas psicológicos impostos pela pandemia de COVID-19, compromete a qualidade do sono e, dessa forma, o sistema imune.

Recurrent sleep paralysis - fear of sleeping / Paralisia do sono recorrente - medo de dormir

ABSTRACT Objective: To report a case of recurrent isolated sleep paralysis (RISP), a benign parasomnia with worrisome and frightening sleep paralysis episodes. Case description: We describe a case of RISP in a sixteen-year-old girl who seeks medical attention for anxiety symptoms. The sleep paralysis and associated auditory and tactile hallucinations began three years before with worsening in the last year, causing fear of sleeping. The episodes were intensely frightening causing negative impact in patient's sleep, school performance and social function. Medical conditions were excluded, and she started treatment with a selective serotonin reuptake inhibitor with complete resolution of symptoms. Comments: Sleep complaints are often devalued. Therefore, clinicians should actively ask their patients about their sleep during health assessment.

RESUMO Objetivo: Relatar um caso de paralisia do sono isolada e recorrente (PSIR), uma parassonia benigna com episódios inquietantes e assustadores de paralisia do sono. Descrição do caso: Descreve-se um caso de PSIR de uma adolescente de dezesseis anos que buscou cuidados médicos devido a sintomas de ansiedade. A paralisia do sono e as alucinações auditivas e táteis associadas haviam começado três anos antes, com agravamento no último ano, causando medo de dormir. Os episódios eram extremamente perturbadores, gerando um impacto negativo no sono, desempenho escolar e vida social da paciente. Condições médicas foram excluídas e começou um tratamento com um inibidor seletivo da recaptação de serotonina, com resolução completa dos sintomas. Comentários: Queixas relacionadas ao sono são frequentemente subvalorizadas. Portanto, os médicos devem perguntar aos seus pacientes sobre problemas relacionados com o sono durante a avaliação clínica.

Fatigue correlates with sleep disturbances in Parkinson disease / 中华医学杂志(英文版)

BACKGROUND@#Many Parkinson disease (PD) patients complain about chronic fatigue and sleep disturbances during the night. The objective of this study is to determine the relationship between fatigue and sleep disturbances by using polysomnography (PSG) in PD patients.@*METHODS@#Two hundred and thirty-two PD patients (152 with mild fatigue and 80 with severe fatigue) were recruited in this study. Demographic information and clinical symptoms were collected. Fatigue severity scale (FSS) was applied to evaluate the severity of fatigue, and PSG was conducted in all PD patients. FSS ≥4 was defined as severe fatigue, and FSS <4 was defined as mild fatigue. Multivariate logistic regression and linear regression models were used to investigate the associations between fatigue and sleep disturbances.@*RESULTS@#Patients with severe fatigue tended to have a longer duration of disease, higher Unified Parkinson Disease Rating Scale score, more advanced Hoehn and Yahr stage, higher daily levodopa equivalent dose, worse depression, anxiety, and higher daytime sleepiness score. In addition, they had lower percentage of rapid eye movement (REM) sleep (P = 0.009) and were more likely to have REM sleep behavior disorder (RBD) (P = 0.018). Multivariate logistic regression analyses found that the presence of RBD and proportion of REM sleep were the independent predictors for fatigue. After the adjustment of age, sex, duration, body mass index, severity of disease, scores of Hamilton Rating Scale for Depression, Hamilton Anxiety Rating Scale, and other sleep disorders, proportion of REM sleep and degree of REM sleep without atonia in patients with PD were still associated with FSS score.@*CONCLUSION@#Considering the association between fatigue, RBD, and the altered sleep architecture, fatigue is a special subtype in PD and more studies should be focused on this debilitating symptom.

Perda de qualidade do sono e fatores associados em mulheres climatéricas / Loss of quality of sleep and associated factors among menopausal women

Resumo O objetivo deste artigo é identificar a prevalência de perda da qualidade do sono em mulheres climatéricas e os fatores associados. Estudo quantitativo, transversal e analítico, cujas variáveis foram investigadas por questionário estruturado/pré-testado e pelo Índice de Qualidade do Sono de Pittsburgh, em 819 mulheres climatéricas assistidas pela Estratégia Saúde da Família. Regressão de Poisson simples foi utilizada para triagem das variáveis (p < 0, 25). Para a modelagem hierarquizada foi utilizada a regressão de Poisson, adotando nível de significância de 5%. Identificou-se perda de qualidade do sono em 67% da amostra. Variáveis como idade avançada (RP = 1,09; IC = 1,03 - 1,16), sintomas climatéricos moderados e intensos (RP = 1,18; IC = 1,10 - 1,27), ansiedade moderada e grave (RP = 1,17; IC = 1,10 - 1,25), depressão moderada/grave (RP = 1,08; IC = 1,01 - 1,15) e artrite/artrose/reumatismo (RP = 1,07; IC = 1,01 - 1,14) demonstraram associações estatisticamente significativas com a perda de qualidade do sono. A perda de qualidade do sono foi altamente prevalente na população estudada. Os fatores associados à perda da qualidade do sono foram idade avançada, sintomas climatéricos de moderados a intensos, ansiedade e depressão moderada a intensa e presença de artrite/artrose/reumatismo.

Abstract The scope of this article is to identify the prevalence of the loss of quality of sleep and associated factors among menopausal women. It is a quantitative, cross-sectional and analytical study, the variables of which were investigated by applying a structured/pre-tested questionnaire and the Pittsburgh Sleep Quality Index with 819 menopausal women cared for under the Family Health Strategy. Simple Poisson regression was used to screen the variables (p < 0.25). For multiple analysis, Poisson regression was used based on a hierarchical model, at a significance level of 5%. Loss of quality of sleep was identified in 67% of the sample. Variables such as advanced age (PR = 1.09; CI = 1.03-1.16), moderate and severe menopausal symptoms (PR = 1.18; CI = 1.10-1.27), moderate to severe anxiety (PR = 1.17; CI = 1.10-1.25), moderate to severe depression (PR = 1.08; CI = 1.01-1.15) and arthritis/arthrosis/rheumatism (PR = 1. 07; CI = 1.01 - 1.14) revealed statistically significant associations with loss of quality of sleep. The loss of quality of sleep was highly prevalent in the population studied. Factors associated with loss of quality of sleep were advanced age, moderate to severe menopausal symptoms, moderate to severe anxiety and depression, and the presence of arthritis/arthrosis/rheumatism.

Sleep quality is inversely related to body mass index among university students

SUMMARY OBJECTIVE: The purpose of this study was to investigate the prevalence of overweight and obesity and its association with sleep quality in university students from the Anhui province in China. METHODS: A cross-sectional study was conducted in China with 1328 participants. The prevalence of underweight and obesity in university students was estimated according to the reference working group on obesity in China. The sleep quality was evaluated using the standard PSQI (Pittsburgh Sleep Quality Index). RESULTS: This study included 470 male and 858 female students from a university in Anhui; 4.4% of the females and 17.7% of the males were overweight or obese. The prevalence of obesity in males was significantly higher than in females, and the prevalence of obesity in higher years was greater than in other years (p<0.05). In general, the mean score for sleep quality was 4.91±2.67; 36.5% of male and 39.1% of female students had poor sleep quality (PSQI score >5). Among the seven components of sleep quality, sleep duration and the use of sleep medication showed significant differences between male and female students and different years (p<0.05). An obvious correlation was found between sleep quality and body mass index (BMI)(p<0.000) in females who took hypnotic drugs. CONCLUSION: This study suggests that the sleep quality of females is probably associated with their BMI. College students are a special group of young adults whose cause of poor sleeping quality and BMI may be significant to study, so the health status of university students can be improved.

RESUMO OBJETIVO: O objetivo do estudo era investigar a prevalência de sobrepeso e obesidade e sua relação com a qualidade do sono em estudantes universitários da província de Anhui, China. METODOLOGIA: Um estudo transversal foi realizado na China com 1328 participantes. A prevalência de baixo peso e obesidade em estudantes universitários foi estimada com base nas referências do Grupo de Trabalho sobre Obesidade da China. A qualidade do sono foi avaliada utilizando o padrão PSQI (Pittsburgh Sleep Quality Index). RESULTADOS: O estudo incluiu 470 homens e 858 mulheres, todos estudantes universitários de Anhui; 4,4% das mulheres e 17,7% dos homens foram classificados com sobrepeso ou obesidade. A prevalência da obesidade em homens foi significativamente maior do que em mulheres, e a prevalência da obesidade nos últimos anos foi maior do que em outras categorias (P < 0, 05). Em geral, a pontuação média de qualidade do sono foi 4,91 ± 2,67; 36,5% dos homens e 39, 1% das mulheres tiveram uma qualidade de sono ruim (PSQI > 5). Considerando os sete componentes da qualidade do sono, a duração do sono e o uso de medicação para dormir apresentaram diferenças significativas entre estudantes homens e mulheres de anos diferentes (P < 0,05). Uma clara correlação foi encontrada entre a qualidade do sono e o Índice de Massa corporal (IMC) (P < 0.0000) em mulheres que usavam drogas hipnóticas. CONCLUSÃO: Este estudo sugere que a qualidade do sono das mulheres está provavelmente associada com o IMC. Os universitários são um grupo especial de jovens adultos, por isso é importante para estudar a causa da sua má qualidade do sono e sua relação com o IMC, para que seja possível melhorar a saúde dos estudantes universitários.

Leucotrienos urinarios en pacientes pediátricos con trastorno respiratorio del sueño secundario a hiperplasia adenoamigdalina / Urinary leukotrienes in pediatric patients with sleep disordered breathing secondary to adenotonsillar hypertrophy

RESUMEN Introducción: El trastorno respiratorio del sueño (TRS) afecta al 2% a 3% de la población pediátrica, siendo la hiperplasia adenoamigdalina (HAA) su principal causa. Se ha observado un aumento en los niveles de leucotrienos excretados en orina (LTU) en estos pacientes, los cuales se correlacionarían con la severidad de la enfermedad. Objetivo: Determinar el nivel de LTU en niños con TRS e HAA antes y después de adenoamigdalectomía (AA), y en controles sanos. Correlacionar los niveles de LTU con los síntomas de TRS. Material y método: Estudio prospectivo. Se incluyeron pacientes con TRS e HAA (n =12) y controles sanos (n =12). Se determinó la concentración de LTU en ambos grupos de forma basal y un mes después de cirugía en el grupo con TRS. Resultados: No hubo diferencias en los niveles de LTU antes y después de AA. Tampoco existieron diferencias entre el grupo control y grupo TRS previo a la cirugía. No se encontró asociación entre LTU y la severidad de síntomas respiratorios. Conclusión: Los LTU no se encuentran elevados en pacientes con TRS e HAA, no disminuyen luego de AA y no se correlacionan con la severidad de los síntomas. La medición de LTU no sería una herramienta útil en la evaluación de pacientes con TRS. Nuevos estudios son necesarios para evaluar el rol de los leucotrienos en esta enfermedad.

ABSTRACT Introduction: Sleep disorder breathing (SDB) affects 2%-3% of the pediatric population, being adenotonsillar hyperplasia (ATH) its main cause. An increase in the levels of urinary leukotrienes (ULT) has been measured in these patients, which could be correlated with the severity of the disease. Aim: To determine the level of ULT in children with SDB and ATH before and after adenotonsillectomy, and healthy controls. To correlate the levels of ULT with symptoms of SDB. Material and method: prospective study. SDB and ATH patients (n =12) and healthy controls (n =12) were included. The concentration of ULT in both groups was determined, before surgery and after a month of surgery. Results: There were no differences in the levels of ULT before and after tonsillectomy in the studied group. There were also no differences between the control group and the SDB group. No association was observed between the level of ULT and the severity of respiratory symptoms. Conclusions: ULT are not elevated in patients with SDB and ATH and they do not decrease after adenotonsillectomy. ULT are not correlated with the severity of the symptoms of SDB. The measurement of ULT would not be a useful tool in the evaluation of patients with SDB. New studies are needed to assess the role of the role of leukotrienes in this disease.

Incidencia y factores condicionantes del insomnio en pacientes ingresados en hospital de alta tecnología / Incidence and Conditioning Factors of Insomnia in Patients Admitted in High-technology Hospital

RESUMEN Introducción: La población sufre insomnio en 30-35 por ciento, pero esta proporción aumenta con la hospitalización. Es necesario un sueño adecuado para una mejor recuperación del paciente ingresado. Objetivo: Analizar la incidencia y los factores condicionantes del insomnio en pacientes hospitalizados. Métodos: Estudio descriptivo observacional transversal. La población objeto de estudio fueron pacientes ingresados en unidades de hospitalización con episodio de insomnio durante su ingreso. De 4650 ingresos anuales, se obtuvo una muestra de 362 pacientes. Se utilizó la Escala Atenas de Insomnio para evaluar el grado de insomnio de los pacientes y listado de causas de insomnio para identificar motivos desencadenantes entre los pacientes con algún episodio declarado. Resultados: Con incidencia de 11 por ciento de insomnio agudo hospitalario, la puntuación total de la Escala Atenas del Insomnio fue de media 7,81 (IC95 por ciento 7,34 8,27) en un rango de 0-24. La habitación doble empeoró los resultados de insomnio (p < 0,01). Las edades mínimas y máximas de la muestra obtuvieron los peores resultados de insomnio, y el tratamiento hipnótico hospitalario mejoró los resultados (p < 0,01). Los problemas respiratorios coincidieron con los peores resultados del test (p < 0,01). Las causas de insomnio con repercusión en los peores resultados fueron "Molestias compañero de habitación", "Ruidos en Unidad de Hospitalización", "Incomodidad de cama/colchón", "Miedo/Ansiedad y "Dolor". Género y acompañamiento familiar no influyeron en insomnio (p > 0,05). Conclusiones: La incidencia de insomnio agudo de pacientes ingresados fue baja, debido principalmente a edad, tratamiento somnífero, enfermedad respiratoria, tipo de habitación, ruido, miedo/ansiedad y dolor, sin influencia del acompañamiento familiar(AU)

ABSTRACT Introduction: 30-35 percent of the population suffers from insomnia, but this proportion increases with hospitalization. Adequate sleep is necessary for a better recovery of the hospitalized patient. Objective: To analyze the incidence and the factors conditioning insomnia in hospitalized patients. Methods: Cross-sectional, observational and descriptive study. The study population consisted of patients admitted to hospitalization units and who presented insomnia during admission. Of 4650 annual admissions, a sample of 362 patients was obtained. The Athens Insomnia Scale was used for assessing the degree of insomnia of the patients and listing the causes of insomnia in order to identify triggers among patients with a declared episode. Results: With an incidence of 11 percent of acute hospital insomnia, the total average score of the Athens Insomnia Scale was 7.81 (95 percent CI 7.34; 8.27) in a range of 0-24. The double room worsened the results of insomnia (p < 0.01). The minimum and maximum ages of the sample obtained the worst results of insomnia, and the hypnotic hospital treatment improved the results (p < 0.01). Respiratory problems coincided with the worst test results (p < 0.01). The causes of insomnia with an impact on the worst results were discomfort caused by the roommate, noise in the hospitalization unit, bed or mattress discomfort, fear/anxiety, and pain. Gender and family support did not influence insomnia (p >0.05). Conclusions: The incidence of acute insomnia in admitted patients was low, mainly due to age, sleeping treatment, respiratory disease, type of room, noise, fear/anxiety, and pain, without the influence of family support(AU)

Trastorno por déficit de atención e hiperactividad más allá de la adolescencia ¿tiempo de pensar diferente? / Attention deficit hyperactivity disorder beyond adolescence. Time to think different?

El trastorno por déficit de atención e hiperactividad (TDAH) es un desorden del neurodesarrollo caracterizado por un patrón de inatención-desorganización e hiperactividad-impulsividad más grave que lo esperado para el nivel de desarrollo de acuerdo con la edad del individuo. Para el diagnóstico es necesario, además, que este comportamiento produzca alteraciones en las distintas áreas de funcionamiento del afectado en comparación con individuos similares de su entorno. Se han publicado extensas revisiones sobre las comorbilidades psiquiátricas asociadas con el TDAH, pero se ha dedicado poca atención a su efecto en la salud general. En este trabajo se revisan algunos de los problemas de medicina general del adulto más frecuentemente asociados con el diagnóstico de TDAH, tales como tabaquismo, adicción, accidentes, trastornos de sueño, obesidad, hipertensión, diabetes, y muerte temprana. Hoy se requiere un seguimiento más cercano de los afectados con TDAH, no solo desde el punto de vista psiquiátrico sino también en lo referente a la atención médica general, para prevenir su impacto sistémico que en la adultez lleva a enfermedades crónicas graves y costosas para los sistemas de salud, los individuos y la sociedad. Estas consecuencias tienen repercusiones médicas muy serias que exceden lo académico y lo emocional y deben ser consideradas por equipos multidisciplinarios.

ADHD is a neurodevelopmental disorder characterized by a pattern of severe inattention-disorganization and/or hyperactivity-impulsivity beyond what is expected for individuals with a comparable development level. These behaviors impair daily life activities of patients in more than one environment and impact their performance and abilities compared with their peers. Extensive reviews have been published about the psychiatric comorbidities associated with ADHD but little attention has been given to the overall impact of ADHD on health. This study reviews some of the most common problems in medical care associated with ADHD like smoking, substance use, accident risk, sleep disorders, obesity, hypertension, diabetes, and early mortality. Today, a close follow-up of patient with ADHD is necessary not only from the psychiatric perspective but also in regard to general medicine issues to prevent the impact on health of those medical co-morbidities. Such conditions can end in severe chronic diseases with consequences and high cost for the individuals, the families and the society far beyond the academic and emotional impact frequently described as associated to ADHD. This condition has serious repercussions on health which need a medical multidisciplinary approach.
