    Delta sleep instability in children with chronic arthritis
    (Associação Brasileira de Divulgação Científica, 2008-10-01) Lopes, Maria Cecília [UNIFESP]; Guilleminault, Christian; Rosa, Agostinho da; Passarelli, Cassia [UNIFESP]; Roizenblatt, Suely [UNIFESP]; Tufik, Sergio [UNIFESP]; Universidade Federal de São Paulo (UNIFESP); Stanford University Sleep Disorders Clinic; Evolutionary Systems and Biomedical Engineering Laboratory
    The objective of the present study was to evaluate the expression of a cyclic alternating pattern (CAP) in slow wave sleep (SWS) in children with the well-defined chronic syndrome juvenile idiopathic arthritis (JIA). Twelve patients (9-17 years of age), 7 girls, with JIA were compared to matched controls by age, pubertal stage and gender. After one night of habituation in the sleep laboratory, sleep measurements were obtained by standard polysomnography with conventional sleep scoring and additional CAP analyses. The sleep parameters of the JIA and control groups were similar for sleep efficiency (91.1 ± 6.7 vs 95.8 ± 4.0), sleep stage in minutes: stage 1 (16.8 ± 8.5 vs 17.8 ± 4.0), stage 2 (251.9 ± 41 vs 262.8 ± 38.1), stage 3 (17.0 ± 6.0 vs 15.1 ± 5.7), stage 4 (61.0 ± 21.7 vs 77.1 ± 20.4), and rapid eye movement sleep (82.0 ± 27.6 vs 99.0 ± 23.9), respectively. JIA patients presented nocturnal disrupted sleep, with an increase in short awakenings, but CAP analyses showed that sleep disruption was present even during SWS, showing an increase in the overall CAP rate (P < 0.01). Overall CAP rate during non-rapid eye movement sleep was significantly higher in pediatric patients who were in chronic pain. This is the first study of CAP in pediatric patients with chronic arthritis showing that CAP analyses can be a powerful tool for the investigation of disturbance of SWS in children, based on sleep EEG visual analysis.

    Improvement of mood and sleep alterations in posttraumatic stress disorder patients by eye movement desensitization and reprocessing
    (Frontiers Research Foundation, 2014-06-10) Raboni, Mara Regina [UNIFESP]; Alonso, Fabiana Fernanda Dias; Tufik, Sergio [UNIFESP]; Suchecki, Deborah [UNIFESP]; Universidade Federal de São Paulo (UNIFESP); Assoc Fundo Incent Pesquisa
    Posttraumatic stress disorder (PTSD) patients exhibit depressive and anxiety symptoms, in addition to nightmares, which interfere with sleep continuity. Pharmacologic treatment of these sleep problems improves PTSD symptoms, but very few studies have used psychotherapeutic interventions to treat PTSD and examined their effects on sleep quality. Therefore, in the present study, we sought to investigate the effects of Eye Movement Desensitization Reprocessing therapy on indices of mood, anxiety, subjective, and objective sleep. the sample was composed of 11 healthy controls and 13 PTSD patients that were victims of assault and/or kidnapping. All participants were assessed before, and 1 day after, the end of treatment for depressive and anxiety profile, general well-being and subjective sleep by filling out specific questionnaires. in addition, objective sleep patterns were evaluated by polysomnographic recording. Healthy volunteers were submitted to the therapy for three weekly sessions, whereas PTSD patients underwent five sessions, on average. Before treatment, PTSD patients exhibited high levels of anxiety and depression, poor quality of life and poor sleep, assessed both subjectively and objectively; the latter was reflected by increased time of waking after sleep onset. After completion of treatment, patients exhibited improvement in depression and anxiety symptoms, and in quality of life; with indices that were no longer different from control volunteers. Moreover, these patients showed more consolidated sleep, with reduction of time spent awake after sleep onset. in conclusion, Eye Movement Desensitization and Reprocessing was an effective treatment of PTSD patients and improved the associated sleep and psychological symptoms.

    Nocturia x disturbed sleep: a review
    (Springer, 2012-03-01) Furtado, Daniele [UNIFESP]; Hachul, Helena [UNIFESP]; Andersen, Monica L. [UNIFESP]; Castro, Rodrigo A. [UNIFESP]; Girao, Manoel B. [UNIFESP]; Tufik, Sergio [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)
    In this article, we provide a concise review of the literature on nocturia and its interference with sleep and, consequently, on quality of life. There are few studies addressing the possible influences of nocturia on sleep disruption. Nocturia is a potential contributor to sleep disorders because affected individuals experience nonrestorative sleep due to frequent interruptions. We also attempted to determine whether individuals with nocturia wake to urinate or, alternately, urinate because they are awake. This review attempts to outline this specific association by examining the possible interactions with other medical conditions and the pathophysiology and prevalence. Most studies have observed a higher prevalence among women; however, the impact on quality of life is higher in men. Nocturia is not necessarily associated with natural aging. the exploration of these topics provides information to clarify the implications of nocturia on sleep, sleep disruption, and other related consequences. Additional evidence is still required to address the question of whether nocturia leads to disordered sleep or whether disordered sleep leads to nocturia.
