ABSTRACT

INTRODUÇÃO: A qualidade do sono é uma das queixas mais frequentes entre estudantes universitários. OBJETIVOS: Identificar a prevalência de má qualidade do sono e os fatores associados em acadêmicos da área da saúde de uma universidade do Centro-Oeste do Brasil. MÉTODOS: Estudo transversal com uma amostra de 2171 universitários com média de idade de 22,7 (±3,9). O desfecho, sono de má qualidade, foi avaliado por meio da versão brasileira do questionário Pittsburgh Sleep Quality Index (PSQI-BR). As variáveis independentes (demográficas, socioeconômicas e comportamentais) foram avaliadas por meio de um questionário padronizado. As análises multivariadas foram realizadas por meio de Regressão de Poisson, estimando-se as Razões de Prevalências (RP) ajustadas e seus respectivos Intervalos de Confiança de 95% (IC95%). RESULTADOS: A média do escore do PSQI-BR foi 7,0. A prevalência de má qualidade do sono foi de 63,5% (IC95% 61,4-65,5), sendo 60,3% nos homens e 64,8% nas mulheres. Após análise ajustada, auto percepção de saúde razoável/ruim esteve associada com má qualidade do sono em ambos os sexos. Além disso, para os homens, a prevalência de má qualidade do sono foi maior para os estudantes que fumavam; e foi menor para aqueles que consumiam adequadamente frutas, legumes e verduras e eram suficientemente ativos. Já para as mulheres, a prevalência de má qualidade do sono foi maior naquelas com 24 ou mais anos de idade, sem companheiro, que consumiam bebidas alcoólicas e que cursavam medicina. CONCLUSÃO: Verificou-se elevada prevalência do desfecho na amostra. Além disso, a má qualidade do sono ocorre de forma diferente entre homens e mulheres. Ressalva-se a importância do monitoramento da má qualidade do sono em estudantes universitários.


INTRODUCTION: Sleep quality is one of the most frequent complaints among college students. OBJETIVE: To identify the prevalence of poor sleep quality and associated factors in health care academics at a university in the Midwest of Brazil. METHODS: Cross-sectional study with a sample of 2171 university students with a mean age of 22.7 (±3.9). The outcome, poor quality sleep, was assessed using the Brazilian version of the Pittsburgh Sleep Quality Index (PSQI-BR) questionnaire. Independent variables (demographic, socioeconomic and behavioral) were assessed using a standardized questionnaire. Multivariate analyzes were performed using Poisson Regression, estimating the adjusted Prevalence Ratios (PR) and their respective 95% Confidence Intervals (95%CI). RESULTS: The mean score of the PSQI-BR was 7.0. The prevalence of poor sleep quality was 63.5% (95%CI 61.4-65.5), being 60.3% in men and 64.8% in women. After adjusted analysis, reasonable/poor self-rated health was associated with poor sleep quality in both sexes. Furthermore, for men, the prevalence of poor sleep quality was higher for students who smoked; and it was lower for those who adequately consumed fruits and vegetables and were sufficiently active. As for women, the prevalence of poor sleep quality was higher in those aged 24 or over, without a partner, who consumed alcoholic beverages and who were studying medicine. CONCLUSION: There was a high prevalence of the outcome in the sample. Furthermore, poor sleep quality occurs differently between men and women. Thus, we emphasize the importance of monitoring poor sleep quality in college students.

ABSTRACT

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.

ABSTRACT

There is a known relationship between seizures and sleep deprivation that increases epileptiform abnormalities and slow waves expressed in the EEG, but chronic insomnia, greater in patients with epilepsy (PWEs) than in healthy control, supposedly has a different mechanism linked to a hyperarousability state with increased rapid EEG activity and associated "restless REM". Therefore, there is a complex interaction at various levels between insomnia and epilepsy that may play a role in seizure presentation. The recognized interconnection between mood and anxiety disorders and insomnia should also advise special care in the management of psychiatric comorbidities in PWEs. This article raises questions related to the interaction between the brain basis of insomnia and epilepsy and the triggers of seizures, particularly sleep deprivation.


Há uma relação conhecida entre crises epilépticas e privação de sono que aumenta as anormalidades epileptiformes e as ondas lentas expressas no EEG, mas a insônia crônica, maior em pacientes com epilepsia (PCE) do que no controle saudável, supostamente tem um mecanismo diferente ligado a um estado de hiperexcitabilidade com aumento da atividade rápida do EEG e associado "REM inquieto". Consequentemente, existe uma complexa interação em vários níveis entre a insônia e a epilepsia que pode desempenhar um papel na apresentação das crises. A reconhecida interligação entre transtornos de humor e ansiedade com a insônia também deve aconselhar um cuidado especial no manejo das comorbidades psiquiátricas do PCE. Este artigo levanta questões relacionadas à interação entre a base cerebral da insônia e da epilepsia e os desencadeadores de crises epilépticas, principalmente a privação do sono.

ABSTRACT

Distúrbios do sono e as alterações do estado de humor, quando não tratados, estão associados à perda de produtividade e acidentes de trabalho, resultando em lesões e fatalidade. Esses distúrbios são subdiagnosticados e subtratados em contextos clínicos, porque podem ser assintomáticos e o exame de polissonografia tem custo elevado. Por isso, questionários são usados para realizar uma triagem e detectar profissionais com alto risco de síndrome da apneia obstrutiva do sono, de sonolência diurna excessiva e fadiga. Este estudo teve como objetivo aplicar questionários validados para triagem dos distúrbios do sono e do humor em pilotos civis e analisar os resultados obtidos com a aplicação desses instrumentos. Foram coletados dados de 44 pilotos civis por meio de quatro instrumentos: um questionário para a caracterização sociodemográfica e ocupacional da amostra, a Escala de Sonolência de Epworth para avaliar a presença de sonolência diurna excessiva, o Questionário de Berlim para avaliar a Síndrome da Apneia Obstrutiva do Sono e a Escala de Humor de Brunel para avaliar o estado de humor. A Escala de Sonolência de Epworth mostrou que 25% dos pilotos apresentaram pontuação para sonolência diurna excessiva. De acordo com o Questionário de Berlim, 29,5% apresentaram alto risco para a Síndrome da Apneia Obstrutiva do Sono e pela Escala de Humor de Brunel, o domínio vigor, teve a média mais alta (5,09 ±4,06). Portanto, a utilização dos questionários nos exames de admissão e nos periódicos, pode auxiliar na identificação precoce e no monitoramento de distúrbios do sono e dos estados de humor ao longo do tempo em pilotos civis, priorizando aqueles que deverão ser encaminhados para realizarem estudos do sono.


Sleep disorders and mood state changes, when untreated, are associated with loss of productivity and accidents at work, resulting in injuries and fatality. These disorders are underdiagnosed and undertreated in clinical contexts due to them being asymptomatic and the prohibitive cost of polysomnography exams. For this reason, questionnaires are used to screen and detect professionals at high risk for obstructive sleep apnea syndrome, excessive daytime sleepiness, and fatigue. This study aimed at applying validated questionnaires for screening sleep and mood disorders in civilian pilots and analyzing the results obtained with the application of these instruments. Data were collected from 44 civilian pilots using four instruments: a questionnaire for sociodemographic and occupational characterization of the sample; the Epworth Sleepiness Scale to assess the presence of excessive daytime sleepiness; the Berlin Questionnaire to assess Obstructive Sleep Apnea Syndrome; and the Brunel Mood Scale to assess the mood state. The Epworth Sleepiness Scale showed that 25% of the pilots presented scores for excessive daytime sleepiness. According to the Berlin Questionnaire, 29.5% were at high risk for Obstructive Sleep Apnea Syndrome, and according to the Brunel Mood Scale, the vigor domain presented the highest mean (5.09 ± 4.06). Therefore, the use of questionnaires in admission and periodic exams can assist in the early identification and monitoring of sleep disorders and mood states over time in civilian pilots, prioritizing those who should be referred to sleep studies.

ABSTRACT

A privação de sono é o estado ininterrupto de vigília, ocorrendo quando o sono inadequado leva à diminuição do desempenho e do estado de alerta até uma possível deterioração com efeitos danosos à saúde. O objetivo dessa pesquisa foi sistematizar o conhecimento já produzido a respeito do efeito da privação de sono na tomada de decisão em militares. A revisão sistemática de literatura foi o método escolhido, seguindo os passos preconizados pelo Preferred Reporting Items for Systematic Reviews and Meta-Analyses(PRISMA). A busca foi realizada nas bases PubMed; Scopus; SciELO; biblioteca Cochrane e Web of Science. Critérios de inclusão e exclusão foram previamente definidos para seleção do material encontrado. Um total de 14 artigos, sendo a sua maioria com baixo risco de viés, foram selecionados. Os temas explorados versaram sobre perda de confiança, relativização moral, trabalho em equipe, queda de níveis cognitivos e mudança de atividade elétrica cerebral na privação de sono. As pesquisas apontam para um comprometimento importante para a tomada de decisão frente à privação ou restrição de sono nos temas investigados, evidenciando poucos recursos para minimizar esses efeitos.


Sleep deprivation is the uninterrupted state of wakefulness, occurring when inadequate sleep leads to a decrease in performance and alertness, possibly reaching a level of deterioration with harmful health effects. The aim of this research wasto systematize the knowledge produced about the effect of sleep deprivation on decision making in the military. The systematic literature review was the method chosen, following the steps recommended by the Preferred Reporting Items for Systematic Reviews and Meta-Analyzes (PRISMA). The search was carried out on the following databases: PubMed; Scopus; SciELO; Cochrane library and Web of Science. Inclusion and exclusion criteria were previously defined for the selection of the found material. A total of 14 articles, most of them with a low risk of bias, were selected to compose the research results. The themes explored in these articles dealt with the loss of confidence, moral relativization, teamwork, drop-in cognitive levels, and changes in brain electrical activity in sleep deprivation. The research demonstrated significant damage to decision-making under sleep restriction or deprivation regarding the investigated topics, presenting few resources capable of minimizing these effects. There is an urge to investigate the role of physical exercise in this process and, especially, in Brazilian samples.

ABSTRACT

El sueño es una necesidad biológica. Regula las funciones inmunitarias. Las funciones inmunológicas dependen de los ritmos circadianos y del sueño regular. Según estudios previos a la pandemia, la corta duración del sueño o privación de sueño, en la semana cercana a la vacunación, se asocia con respuestas más bajas de anticuerpos. La privación de sueño da como resultado una función inmunológica más deficiente (es decir, actividad reducida de las células natural killer, producción de IL-2 suprimida) así como un aumento de los niveles circulantes de marcadores inflamatorios (IL-6, TNF-α [factor de necrosis tumoral] y proteína C reactiva). Los médicos deben ser conscientes de que muchas enfermedades que mencionamos en esta resumida actualización son comórbidas con alteraciones del sueño, y es importante, por ello, enseñar a los pacientes a mejorar su comportamiento con respecto al sueño y fomentar la educación sobre higiene del sueño. Destacamos que, en el interrogatorio de cualquier especialidad médica, deben incorporarse preguntas sobre el "dormir", dado que el sueño de buena calidad es fundamental en la prevención y el tratamiento de diversas enfermedades. (AU)


Sleep is a biological necessity. Regulates immune functions. Immune functions depend on circadian rhythms and regular sleep. According to studies prior to the pandemic, short duration of sleep or sleep deprivation, in the week leading up to vaccination, is associated with lower antibody responses to vaccination. Sleep deprivation results in poorer immune function (i.e., reduced natural killer cell activity, suppressed IL-2 production) as well as increased circulating levels of inflammatory markers (IL-6, factor of tumor necrosis, C-reactive protein). Clinicians should be aware that many illnesses, which we mention in this brief update, are comorbid with sleep disturbances and it is therefore important to teach patients to improve their sleep behavior and should encourage sleep hygiene education . We emphasize that in the questioning of any medical specialty, questions about "sleep" should be incorporated, given that good quality sleep is essential in the prevention and treatment of various diseases.

ABSTRACT

Introdução: a Doença Arterial Periférica (DAP) decorre do estreitamento ou oclusão arterial, que interfere no aporte sanguíneo das extremidades inferiores. A DAP pode levar a um repouso prolongado, causando prejuízos à qualidade de vida e do sono dos pacientes, devido à dor e receio de lesão. Objetivo: descrever o nível de atividade física, a qualidade de vida e do sono em pacientes com DAP. Metodologia: trata-se de um estudo observacional, epidemiológico e transversal, realizado no Hospital Geral de Camaçari-BA. Foram incluídos pacientes com diagnóstico de DAP, ambos os sexos, com idade superior a 18 anos, internados no referido hospital. Foram excluídos os pacientes com distúrbios psiquiátricos e dificuldade de compreensão dos questionários. Para a avaliação do nível de atividade física foi utilizado o Questionário Internacional de Atividade física, para Qualidade de Vida o questionário Short Form Health Survey 36, para qualidade do sono Índice de Qualidade do Sono de Pittsburgh e para Claudicação Intermitente o Questionário de Edimburgo. Resultados: dos 27 pacientes analisados, 55,6% (15/27) eram do sexo feminino e 44,4% (12/27) masculino, 37% (10/27) de cor/raça preta. A média de idade foi de 62,6±8,3 anos, peso 71,8±16,2kg, altura 164,8±8,3cm e IMC 26,3±5. A maioria relatou ser ativo, 33,3% (9/27). Segundo a SF-36 o domínio mais limitante foi "dor" (28,6), o escore global do PSQI foi de 10,4 e a maioria (81,5%) não apresentava claudicação intermitente. Conclusão: a presença de DAP foi mais frequente nos idosos e foram identificados a presença de distúrbios do sono e diminuição da qualidade de vida.


Introduction: peripheral Arterial Disease (PAD) is due to narrowing or arterial occlusion, which interferes with the blood supply of the lower extremities. PAD can lead to prolonged rest, causing damage to the quality of life and sleep of patients, due to pain and fear of injury. Objective: to describe the level of physical activity, quality of life and sleep in patients with PAD. Methodology: this is an observational, epidemiological and cross-sectional study, carried out at the Hospital Geral de Camaçari-BA. Patients diagnosed with PAD, both sexes, aged over 18 years, admitted to the hospital were included. Patients with psychiatric disorders and difficulty in understanding the questionnaires were excluded. To assess the level of physical activity, the International Physical Activity Questionnaire was used, for Quality of Life the Short Form Health Survey 36 questionnaire, for sleep quality Sleep Quality Index of Pittsburgh and for Intermittent Claudication the Edinburgh Questionnaire. Results: of the 27 patients analyzed, 55.6% (15/27) were female and 44,4% (12/27) were male, 37% (10/27) were black / colored. The mean age was 62.6 ± 8.3 years, weight 71.8 ± 16.2 kg, height 164.8 ± 8.3 cm and BMI 26.3 ± 5. The majority reported being active, 33.3% (9/27). According to SF-36, the most limiting domain was "pain" (28.6), the global PSQI score was 10.4 and the majority (81.5%) did not have intermittent claudication. Conclusion: the presence of PAD was more frequent in the elderly and the presence of sleep disorders and decreased quality of life was identified.

ABSTRACT

BACKGROUND@#Microglia plays an indispensable role in the pathological process of sleep deprivation (SD). Here, the potential role of microglial CX3C-chemokine receptor 1 (CX3CR1) in modulating the cognition decline during SD was evaluated in terms of microglial neuroinflammation and synaptic pruning. In this study, we aimed to investigat whether the interference in the microglial function by the CX3CR1 knockout affects the CNS's response to SD.@*METHODS@#Middle-aged wild-type (WT) C57BL/6 and CX3CR1-/- mice were either subjected to SD or allowed normal sleep (S) for 8 h to mimic the pathophysiological changes of middle-aged people after staying up all night. After which, behavioral and histological tests were used to explore their different changes.@*RESULTS@#CX3CR1 deficiency prevented SD-induced cognitive impairments, unlike WT groups. Compared with the CX3CR1-/- S group, the CX3CR1-/- SD mice reported a markedly decreased microglia and cellular oncogene fos density in the dentate gyrus (DG), decreased expression of pro-inflammatory cytokines, and decreased microglial phagocytosis-related factors, whereas increased levels of anti-inflammatory cytokines in the hippocampus and a significant increase in the density of spines of the DG were also noted.@*CONCLUSIONS@#These findings suggest that CX3CR1 deficiency leads to different cerebral behaviors and responses to SD. The inflammation-attenuating activity and the related modification of synaptic pruning are possible mechanism candidates, which indicate CX3CR1 as a candidate therapeutic target for the prevention of the sleep loss-induced cognitive impairments.

ABSTRACT

Sleep exerts important functions in the regulation of cognition and emotion. Recent studies have found that sleep disorder is one of the important risk factors for Alzheimer's disease (AD), but the effects of chronic sleep deprivation on the cognitive functions of AD model mice and its possible mechanism are still unclear. In the present study, 8-month-old male APP/PS1/tau triple transgenic AD model (3xTg-AD) mice and wild type (WT) mice (n = 8 for each group) were subjected to chronic sleep deprivation by using the modified multiple platform method, with 20 h of sleep deprivation each day for 21 days. Then, open field test, elevated plus maze test, sugar water preference test, object recognition test, Y maze test and conditioned fear memory test were performed to evaluate anxiety- and depression-like behaviors, and multiple cognitive functions. In addition, the immunohistochemistry technique was used to observe pathological characteristics in the hippocampus of mice. The results showed that: (1) Chronic sleep deprivation did not affect anxiety- (P = 0.539) and depression-like behaviors (P = 0.874) in 3xTg-AD mice; (2) Chronic sleep deprivation exacerbated the impairments of object recognition memory (P < 0.001), working memory (P = 0.002) and the conditioned fear memory (P = 0.039) in 3xTg-AD mice; (3) Chronic sleep deprivation increased amyloid β (Aβ) deposition (P < 0.001) and microglial activation (P < 0.001) in the hippocampus of 3xTg-AD mice, without inducing abnormal tau phosphorylation and neurofibrillary tangles. These results indicate that chronic sleep deprivation exacerbates the impairments of recognition memory, working memory and conditioned fear memory in 3xTg-AD mice by aggravating Aβ deposition and the excessive activation of microglia in the hippocampus.

ABSTRACT

Narcolepsy is a chronic neurological sleep disorder caused by hypocretin neuron loss, resulting in excessive daytime sleepiness, disturbed nocturnal sleep, and intrusions of aspects of rapid eye movement sleep in wakefulness, such as cataplexy, sleep paralysis, and hypnopompic/hypnagogic hallucinations. Narcolepsy disrupts the maintenance and orderly occurrence of the wake and sleep stages. Cataplexy is a highly specific symptom of narcolepsy, but many other symptoms can be observed in a variety of sleep disorders. The diagnosis of narcolepsy type 1 requires a history of excessive daytime sleepiness and one of the following : 1) a low cerebrospinal fluid hypocretin-1 level or 2) cataplexy and a positive multiple sleep latency test result. The diagnosis of narcolepsy type 2 requires a history of excessive daytime sleepiness and a positive mean sleep-latency test result. The mean sleep-latency test must be preceded by nighttime polysomnography to exclude other sleep disorders and to document adequate sleep. The mean sleep-latency test result can be falsely positive in other sleep disorders, such as shift work, sleep apnea, or sleep deprivation, and it is influenced by age, sex, and puberty. Modafinil and armodafinil can reduce the excessive daytime sleepiness without many of the side effects associated with older stimulants. Although there is no cure for narcolepsy, the treatments are often effective and include both behavioral and pharmacologic approaches.

ABSTRACT

Abstract Objective: To evaluate sleep quality and excessive daytime sleepiness in undergraduate dentistry students. Material and Methods: This research is characterized as an observational study of transversal type, having analysed undergraduate students in dentistry from a public university in the State of Pernambuco, Brazil. The sample consisted of 325 students enrolled between the 1st and 10th academic semester. Sleep quality was evaluated using the Pittsburgh Sleep Quality Index (PSQI), while excessive daytime sleepiness was analysed through the Epworth Sleepiness Scale (ESS). The t-Student and Mann-Whitney tests were used for the numerical values, with the F-test (ANOVA) or the Kruskal-Wallis test being used to compare more than two categories. Results: It was observed that 71.1% of students presented a poor sleep quality, with more than half of the students exhibiting excessive daytime sleepiness (58.1%). A relationship between sleep quality and the academic semester was verified. However, gender and age were not associated with sleep quality or with excessive daytime sleepiness. Conclusion: A high prevalence of poor sleep quality and excessive daytime sleepiness was observed among undergraduate students in dentistry. The data suggest that the undergraduate degree in Dentistry can influence the students' quality of sleep, regardless of age or gender.

ABSTRACT

BACKGROUND: In modern societies, sleep deprivation is a serious health problem. This problem could be induced by a variety of reasons, including lifestyle habits or neurological disorders. Chronic sleep deprivation (CSD) could have complex biological consequences, such as changes in neural autonomic control, increased oxidative stress, and inflammatory responses. The superior cervical ganglion (SCG) is an important sympathetic component of the autonomic nervous system. CSD can lead to a wide range of neurological consequences in SCG, which mainly supply innervations to circadian system and other structures. As the active component of Curcuma longa, curcumin possesses many therapeutic properties; including neuroprotective. This study aimed to evaluate the effect of CSD on the SCG histomorphometrical changes and the protective effect of curcumin in preventing these changes. METHODS: Thirty-six male rats were randomly assigned to the control, curcumin, CSD, CSD + curcumin, grid floor control, and grid floor + curcumin groups. The CSD was induced by a modified multiple platform apparatus for 21 days and animals were sacrificed at the end of CSD or treatment, and their SCGs removed for stereological and TUNEL evaluations and also spatial arrangement of neurons in this structure. RESULTS: Concerning stereological findings, CSD significantly reduced the volume of SCG and its total number of neurons and satellite glial cells in comparison with the control animals ( P < 0.05). Treatment of CSD with curcumin prevented these decreases. Furthermore, TUNEL evaluation showed significant apoptosis in the SCG cells in the CSD group, and treatment with curcumin significantly decreased this apoptosis ( P < 0.01). This decrease in apoptosis was observed in all control groups that received curcumin. CSD also changed the spatial arrangement of ganglionic neurons into a random pattern, whereas treatment with curcumin preserved its regular pattern. CONCLUSIONS: CSD could potentially induce neuronal loss and structural changes including random spatial distribution in the SCG neurons. Deleterious effects of sleep deprivation could be prevented by the oral administration of curcumin. Furthermore, the consumption of curcumin in a healthy person might lead to a reduction of cell death.

ABSTRACT

RESUMEN Introducción: La somnolencia diurna excesiva (SDE) puede llegar a interferir en el desempeño académico y profesional, debido a que las personas afectadas tienden a quedarse dormidas en situaciones que exigen un alto nivel de atención. Los estudiantes de Medicina representan una población en riesgo de SDE, dada la exigencia académica de numerosas horas de estudio, debido al gran número de créditos por asignatura contenidos en el plan de estudios del programa académico, las prácticas docentes asistenciales y los turnos nocturnos, que pueden generar privación o déficit acumulado del sueño. Por esta razón, es importante estimar la prevalencia de SDE y los factores asociados en estudiantes de Medicina de una institución de educación superior (IES) de Bucaramanga, con el objetivo de implementar estrategias de prevención primaria que disminuyan la presentación de este problema y mejoren la calidad de vida y el desempeño académico de los estudiantes. Material y métodos: Estudio transversal analítico observacional, con una muestra poblacional de 458 estudiantes de Medicina matriculados en el segundo semestre de 2015 en la Universidad Autónoma de Bucaramanga (UNAB), quienes respondieron a 4 cuestionarios: variables sociodemográficas, escala de somnolencia de Epworth, índice de calidad del sueño de Pittsburg (ICSP) e índice de higiene del sueño (IHS). Se realizó el análisis bivariable y multivariable en busca de asociación con SDE. Resultados: Los estudiantes tenían una media de edad de 20,3 arios; de los 458 encuestados, el 62,88% eran mujeres. Se estableció que el 80,75% de los participantes tenían SDE y el 80,55%, una percepción negativa de la calidad del sueño (OR = 1,91;IC95%, 1,11-3,29; p = 0,019). En el análisis multivariable, se encontró que el hecho de estar cursando ciencias clínicas disminuye el riesgo de SDE respecto a quienes estaban cursando el ciclo básico. Además, se observó que una puntuación > 15 en el IHS aumenta de manera significativa el riesgo de padecer SDE. Conclusiones: Aunque es frecuente encontrar SDE en los estudiantes de Medicina, solo un pequeño porcentaje de ellos sufren la forma severa de este trastorno del sueño. Estar cursando asignaturas del ciclo básico se asocia con mayor riesgo de SDE, por lo cual es importante que los comités curriculares de las IES evalúen regularmente la cantidad de horas de trabajo supervisado e independiente que realizan los estudiantes de Medicina. Finalmente, es importante emprender campañas orientadas a mejorar la percepción de riesgo sobre el uso de bebidas energizantes de los estudiantes universitarios y realizar, desde el ingreso al programa académico, recomendaciones sobre los hábitos de higiene del sueño.


ABSTRACT Introduction: Excessive daytime sleepiness (EDS) can interfere with academic and professional performance, as affected individuals tend to fall asleep in situations that demand a high level of alertness. Medical students are often a population at risk of suffering from EDS due to the demanding number of study hours, the significant number of credits per subject in the academic curriculum, practical teaching sessions and hospital night shifts, which can lead to sleep deprivation or sleep debt. It is for these reasons that it is important to estimate the prevalence of EDS and its associated factors in medical students of a Higher Education Institution (HEI) in Bucaramanga, in order to implement early prevention strategies to reduce the occurrence of this problem and to improve the students' quality of life and academic performance. Material and methods: An observational, cross-sectional analytical study with a population sample of 458 medical students enrolled in the second semester of 2015 at the Universidad Autonomade Bucaramanga (UNAB), who completed four questionnaires: Sociodemographic Variables, Epworth Sleepiness Scale, Pittsburgh Sleep Quality Index and Sleep Hygiene Index (SHI). A bivariate and multivariate analysis was performed to identify any correlations with EDS. Results: Mean student age was 20.3 years and 62.88% of the 458 respondents were women. We were able to establish that 80.75% of participants suffered from EDS and 80.55% had a negative perception of their sleep quality (OR=1.91; 95% CI, 1.11-3.29; p =0.019). In the multivariate analysis, it was found that the risk of EDS is lower in the clinical sciences than in the basic cycle. Furthermore, it was noted that a score higher than 15 in the Sleep Hygiene Index significantly increases the risk of suffering from EDS. Conclusions: Although EDS is very common in medical students, only a small percentage present the most severe form of this sleep disorder. Being enrolled in basic cycle subjects is associated with a higher risk of suffering EDS, so it is important for the curriculum committees of higher education institutions to regularly evaluate the number of hours of supervised and independent work performed by medical students. Finally, it is important to implement campaigns aimed at improving university students' perception of the risk of taking energy drinks and to establish sleep hygiene recommendations from the start of the academic programme.

ABSTRACT

Objective: To evaluate whether exposing rats to individual or combined environmental stressors triggers endophenotypes related to mood and anxiety disorders, and whether this effect depends on the nature of the behavior (i.e., innate or learned). Methods: We conducted a three-phase experimental protocol. In phase I (baseline), animals subjected to mixed schedule of reinforcement were trained to press a lever with a fixed interval of 1 minute and a limited hold of 3 seconds. On the last day of phase I, an open-field test was performed and the animals were divided into four experimental groups (n=8/group). In phase II (repeated stress), each group was exposed to either hot air blast (HAB), paradoxical sleep deprivation (PSD) or both (HAB+PSD group) on alternate days over a 10-day period. Control group animals were not exposed to stressors. In phase III (post-stress evaluation), behavior was analyzed on the first (short-term effects), third (mid-term effects), and fifth (long-term effects) days after repeated stress. Results: The PSD group presented operant hyperactivity, the HAB group presented spontaneous hypoactivity and anxiety, and the HAB+PSD group presented spontaneous hyperactivity, operant hypoactivity, impulsivity, loss of interest, and cognitive impairment. Conclusion: A combination of environmental stressors (HAB and PSD) may induce endophenotypes related to bipolar disorder.

ABSTRACT

Objetivo: Evaluar la duración del sueño y fenotipos circadianos y su asociación con variables sociodemográficas y clínicas, de estilo de vida e indicadores de riesgo cardiometabólico en mujeres adultas. Materiales y métodos: Estudio transversal de 108 mujeres adultas residentes de la ciudad de Valencia, Venezuela atendidas en jornadas de salud. Se establecieron variables sociodemográficas, clínicas y estilo de vida, duración de sueño autoinformada durante la semana, fin de semana y ponderada (corta: < 7 h o larga: > 9 h) y fenotipo circadiano o cronotipo mediante la versión reducida del cuestionario de matutinidad de Horne y Östberg. Se midieron presión arterial, peso, talla, circunferencia de cintura y biomarcadores en sangre venosa. Se calcularon tres puntajes de estatus cardiometabólico. Se estableció hipertensión arterial (HTA) y síndrome metabólico (SM). Resultados: Se encontró duración corta de sueño ponderada en 21,3 % de las mujeres y duración larga ponderada en 16,7 %. El 28,7 % mostró cronotipo claramente matutino; 38 %, moderadamente matutino; 32,4 %, indefinido y 0,9 %, moderadamente vespertino, sin casos de cronotipo claramente vespertino. La duración corta de sueño y los cronotipos matutinos fueron más frecuentes en mujeres mayores de 40 años. La duración de sueño se asoció a estado civil, ocupación y condición de exfumadora; los cronotipos se asociaron a posmenopausia. La duración corta se asoció a obesidad abdominal e hipertensión arterial (HTA), elevación de gamma-glutamil transferasa y ácido úrico. La duración larga se asoció a glicemia y transaminasas más elevadas. El cronotipo claramente matutino se asoció a HTA, SM y número de componentes del SM presentes. La duración corta de sueño y el cronotipo claramente matutino predijeron elevado riesgo cardiometabólico, al ajustar por edad y posmenopausia esta asociación desapareció. Conclusiones: La duración subóptima del sueño y los fenotipos circadianos se asociaron a variables socio demográficas, clínicas y de riesgo cardiometabólico. La duración corta de sueño y el cronotipo claramente matutino predijeron elevado riesgo cardiometabólico.


Objective: To evaluate the sleep duration, the circadian phenotypes, and their association with sociodemographic and clinical variables, lifestyle, and indicators of cardiometabolic risk in adult women.Materials and methods: A cross-sectional study of 108 adult women living in the city of Valencia, Venezuela, who were treated in health campaigns. Sociodemographic and clinical variables, lifestyle, self-reported sleep duration during weekdays and weekends, and weighted sleep duration (short: <7 hours or long: >9 hours) were determined. The circadian phenotype or chronotype were assessed by the reduced Horne & Östberg's morningness-eveningness questionnaire. Blood pressure, weight, height, waist circumference, and blood biomarkers were measured. Three (3) cardiometabolic status scores were calculated. Hypertension (HTN) and metabolic syndrome (MS) were established. Results:Twenty one point three percent (21.3 %) of the study population presented a short weighted sleep duration and 16.7 % presented a long one. Twenty-eight point seven percent (28.7 %) showed a clearly morning chronotype, 38 % showed a moderately morning chronotype, 32.4 % showed no definite chronotype, 0.9 % showed a moderately evening chronotype, and there were no cases of clearly evening chronotype. Short sleep duration and morning chronotypes were more frequent in women > 40 years. The sleep duration was associated with marital status,occupation and ex-smoker status. The chronotypes were associated with postmenopause. The short sleep duration was associated with abdominal obesity and HTN, and elevation of gamma-glutamyltransferase and uric acid. The long sleep duration was associated with higher glycemia and transaminases. The clearly morning chronotype was associated with HTN, MS and presence of a number of MS components. The short sleep duration and the clearly morning chronotype predicted a high cardiometabolic risk. This association disappeared by adjusting the age and postmenopause status. Conclusions: The suboptimal sleep duration and the circadian phenotypes were associated with sociodemographic, clinical and cardiometabolic risk variables. The short sleep duration and the clearly morning chronotype predicted a high cardiometabolic risk.

ABSTRACT

ABSTRACT Objective: To analyze the contribution of subjective sleep need for daytime sleepiness in adolescents, and to compare questions about sleep, age and body mass index between adolescents who considered to sleep enough and those who reported the need for more sleep. Methods: This is a descriptive, epidemiological and cross-sectional study. Data collection was performed in August 2016, with 773 adolescents aged 14-19 years old, from Paranaguá, Paraná, Southern Brazil. The analysis included the following variables: time in bed, half-sleep phase, sleep need, social jetlag, daytime sleepiness, body mass index and physical activity. Results: The prevalence of adolescents with subjective need for sleep was 73.0%, with an average need of 1.7 extra hours of sleep. These adolescents woke up earlier (p<0.001) and slept less on school days (p<0.001). The need for more sleep was associated with higher daytime sleepiness scores (rho=0.480; p<0.001) and with later half-sleep phase (rho=0.200; p<0.001). No correlation was identified between the sleep need and time in bed (rho=-0.044; p=0.225). The subjective sleep need was the variable with the greatest explanatory power for daytime sleepiness (24.8%; p<0.001). In addition, the less adolescents practiced physical activity, the higher their daytime sleepiness scores (rho=-0.117; p<0.001). Conclusions: The subjective sleep need has an important role in explaining daytime sleepiness among adolescents. Adolescents who needed to sleep more reported waking up early and experienced sleep deprivation during class days; they also woke up later on the weekends and experienced more daytime sleepiness, compared to those who believed they had enough sleep.


RESUMO Objetivo: Analisar a contribuição da necessidade subjetiva de sono para a sonolência diurna em adolescentes e comparar questões sobre sono, idade e índice de massa corporal entre os adolescentes que consideram dormir o suficiente e os que julgam necessitar dormir mais. Métodos: Estudo descritivo, epidemiológico e transversal, cuja coleta de dados ocorreu em agosto de 2016 em 773 adolescentes de 14 a 19 anos de Paranaguá, PR, Brasil. As variáveis de análise foram tempo de cama, meia fase do sono e necessidade de mais horas de sono, além do jetlag social, sonolência diurna, índice de massa corpórea (IMC) e atividade física. Resultados: A prevalência de adolescentes com necessidade subjetiva de sono foi 73,0%, sugerindo precisar, em média, de 1,7 hora a mais de sono. Estes acordavam mais cedo (p<0,001) e dormiam menos nos dias de aula (p<0,001). A necessidade de dormir mais associou-se a maiores pontuações de sonolência diurna (rho=0,480; p<0,001) e com meia fase do sono mais tardia (rho=0,200; p<0,001). Não foi identificada correlação entre necessidade de sono e tempo de cama (rho=-0,044; p=0,225). A necessidade subjetiva de sono foi a variável com maior poder explicativo da sonolência diurna (24,8%; p<0,001). Além disso, quanto menos os adolescentes praticavam atividade física, maiores as pontuações de sonolência diurna (rho=-0,117; p<0,001). Conclusões: A percepção subjetiva de sono teve papel importante para explicar a sonolência diurna dos adolescentes. Os jovens que precisavam dormir mais relataram acordar mais cedo e apresentavam privação de sono durante os dias de aula, acordaram mais tarde no final de semana e apresentaram maior sonolência diurna, comparando-se aos que acreditavam dormir o suficiente.

ABSTRACT

ABSTRACT OBJECTIVE: Analyze the association of work organization and sleep aspects with work ability in regular aviation pilots. METHODS: This is a cross-sectional epidemiological study with 1,234 regular aviation pilots who worked domestic and international flights, affiliated with the Brazilian Association of Civil Aviation Pilots. Data collection employed online questionnaire. We compared proportions using Pearson's Chi-squared or Fisher's exact hypothesis tests. Then, we conducted Poisson analysis, with robust variance, to test factors associated with moderate or low work ability. RESULTS: The prevalence of moderate or low work ability was 43.3%. We found that self-perception of insufficient sleep (PR = 1.29; 95%CI 1.06-1.57), increased perception for fatigue (PR = 1.51; 95%CI 1.24-1.84), more than 65 flight hours per month (PR = 1.22; 95%CI 1.01-1.46), less than 10 days of time off per month (PR = 1.27; 95%CI 1.04-1.55), and frequent operational delays (PR = 1.23; 95%CI 1.02-1.48) were factors associated with moderate or low work ability. CONCLUSIONS: Work organization was a determining factor for decreased work ability, especially concerning aspects related to rest and its influence on the sleep of pilots.


RESUMO OBJETIVO: Analisar a associação da organização do trabalho e dos aspectos do sono com a capacidade para o trabalho entre pilotos da aviação regular. MÉTODOS: Foi realizada uma pesquisa epidemiológica transversal, com 1.234 pilotos da aviação regular, que realizavam voos de rotas nacionais e internacionais, afiliados à Associação Brasileira de Pilotos da Aviação Civil. A coleta de dados foi feita através de questionário on-line. Para comparação entre as proporções foram realizados os testes de hipóteses qui-quadrado de Pearson ou Exato de Fisher. Posteriormente, foi efetuada a análise de Poisson, com variância robusta, para testar os fatores associados à capacidade moderada ou baixa para o trabalho. RESULTADOS: A prevalência de capacidade para o trabalho moderada ou baixa foi de 43,3%. Verificou-se que autopercepção de sono insuficiente (RP = 1,29; IC95% 1,06-1,57), maior percepção para fadiga (RP = 1,51; IC95% 1,24-1,84), jornada de voo maior que 65 horas por mês (RP = 1,22; IC95% 1,01-1,46), menos de 10 dias de folga por mês (RP = 1,27; IC95% 1,04-1,55) e atrasos operacionais frequentes (RP = 1,23; IC95% 1,02-1,48) foram fatores associados à capacidade moderada ou baixa para o trabalho. CONCLUSÕES: A organização do trabalho foi um fator determinante para a diminuição da capacidade para o trabalho, em especial quanto aos aspectos relacionados ao descanso e suas repercussões no sono de pilotos.

ABSTRACT

OBJECTIVES: Bedtime procrastination is defined as going to bed later than intended, without having external reasons for doing so. Despite various studies investigating the new concept of bedtime procrastination, there have been no studies that have validated the Bedtime Procrastination Scale (BPS). Thus, this study aims to validate the BPS in Korean. METHODS: Two hundred twenty seven participants (mean age 22±2.39 years, 81.1% female) participated in the study. All participants completed the BPS, Insomnia Severity Index, Center for Epidemiologic Studies Depression Scale, Perceived Stress Scale, Depressive Symptom Inventory-Suicidality Subscale, and General Procrastination Scale (GPS). Exploratory factor analysis was used to determine number of factors. RESULTS: Exploratory factor analysis revealed support for one factor, which was consistent with the original study. Goodness of fit was adequate for the one factor model [χ²=59.369(df=27, p<0.001), Comparative Fit Index=0.963, Tucker-Lewis Index=0.951, Root Mean Square Error of Approximation= 0.073, Standardized Root Mean Square Residual=0.042]. Internal consistency was also adequate (Cronbach's alpha=0.86). Convergent validity was also high with the GPS (p<0.001, r=0.411). Correlations were also high with other questionnaires (p<0.05). CONCLUSIONS: The BPS is a reliable and valid measure for bedtime procrastination, and may have important clinical implications for sleep disorders.
