Terms modified by Sleep Patterns Selected AbstractsNegotiating Daytime Sleep: An Intercultural Comparison of Social and Cultural Aspects of Sleep Patterns.JOURNAL OF SLEEP RESEARCH, Issue 2006A joint symposium of the WFSRSMS, the ESRS [source] Sleep patterns, sleep disturbances and sleepiness in retired Iranian eldersINTERNATIONAL JOURNAL OF GERIATRIC PSYCHIATRY, Issue 11 2009Seyed Kazem Malakouti Abstract Objectives Complaints of sleep disturbance increase with age and many studies have reported on the relationship of sleep problems to the greater use of health services, physical and mental morbidity, functional decline, and all causes of mortality. This study aimed to examine sleep patterns and sleep disturbances in Iranian elders and correlate their sleep quality to their health status. Methods Four hundred men and women, aged 60 years or older, were interviewed by trained interviewers regarding their physical and mental health status. The Pittsburghh Sleep Quality Index, the Epworth Sleepiness Scale (ESS), and a General Health Questionnaire (GHQ) were then administered to each participant. The data gathered were analyzed using ,2 -test, t -test, and one-way analysis of variance and logistic regression. Results The results indicated that the majority of participants (82.6%) suffered from poor sleep quality and approximately one-third (29.2%) experienced sleepiness during the daytime. Difficulty falling asleep (p,,,0.001) and maintaining sleep (p,,,0.01) and the feeling of being too hot at night (p,,,0.005) were significantly more prevalent in women, but men suffered more from leg twitching (p,,,0.01). Being female (OR,=,2.52), and having GHQ scores of more than 11 (OR,=,4.14) increased the risk of poor sleep quality considerably. Conclusion Promoting sleep hygiene education of elders in primary health care services are recommended. Copyright © 2009 John Wiley & Sons, Ltd. [source] Polysomnography in patients with post-traumatic stress disorderPSYCHIATRY AND CLINICAL NEUROSCIENCES, Issue 3 2010Sinan Yetkin MD Aims:, The purpose of the present study was to investigate sleep structure in post-traumatic stress disorder (PTSD) patients with and without any psychiatric comorbidities. The relationship between sleep variables and measurements of clinical symptom severity were also investigated. Methods:, Sleep patterns of 24 non-medicated male PTSD patients and 16 age- and sex-matched normal controls were investigated on polysomnography on two consecutive nights. Six PTSD-only patients and 15 PTSD patients with major depressive disorder (MDD) were also compared to normal controls. Sleep variables were correlated with PTSD symptoms. Results:, Compared to the normal controls, the PTSD patients with MDD had difficulty initiating sleep, poor sleep efficiency, decreased total sleep time, decreased slow wave sleep (SWS), and a reduced rapid eye movement (REM) sleep latency. The PTSD patients without any comorbid psychiatric disorders had moderately significant disturbances of sleep continuity, and decreased SWS, but no abnormalities of REM sleep. REM sleep latency was inversely proportional to the severity of startle response. SWS was found to be inversely correlated with the severity of psychogenic amnesia. Conclusions:, PTSD patients have disturbance of sleep continuity, and SWS deficit, without the impact of comorbid depression on sleep. The relationship between SWS and the inability to recall an important aspect of trauma may indicate the role of sleep in the consolidation of traumatic memories. The relationship between the severity of the startle response and REM latency may suggest that REM sleep physiology shares common substrates with the symptoms of PTSD. [source] Habitual snoring in an outpatient population in JapanPSYCHIATRY AND CLINICAL NEUROSCIENCES, Issue 4 2000Yuhei Kayukawa MD Abstract In order to investigate the occurrence and history of sleep problems in Japan, the 11-Centre Collaborative Study on Sleep Problems (COSP) project was carried out. Complaints of snoring are examined, and its prevalence, risk factors and screening reliability are discussed. The subjects who participated in the study were 6445 new outpatients from a general hospital. They were asked to answer a sleep questionnaire that consisted of 34 items with seven demographic items; each item was composed of four grades of frequency. In order to offset possible seasonal variations in sleep habits, data were collected across four seasons. Sleep patterns, insomnia, hypersomnia, parasomnia and circadian rhythm sleep disorders were covered. Habitual snoring was seen in 16.0% of males and 6.5% of females. Male predominance was noted. From these data, the relationship between habitual snoring and sleep complaints was statistically analyzed. Habitual snorers (HS) were observed to wake up more frequently during sleep (17.8% of males, 21.5% of females) than were non-habitual snorers (NHS; 6.6% of males, 9.7% of females). Mid-sleep awakening of HS was also more frequent than it was for NHS; however, there were no differences in difficulty in falling asleep and early morning awakening. Body mass index, cigarette smoking and alcohol consumption were also correlated with habitual snoring. [source] Sleep patterns, electronic media exposure and daytime sleep-related behaviours among Israeli adolescentsACTA PAEDIATRICA, Issue 9 2010Tamar Shochat Abstract Aim:, The aim of this study was to assess weekday and weekend sleep patterns and their relationships with electronic media (television and computer) exposure and with daytime sleep-related behaviours, including sleep problem behaviours, sleepiness and fatigue in Israeli adolescents. Methods:, A cross-sectional survey, which includes 470 8th and 9th grade middle school students (mean age 14 ± 0.8) in the normative school system, was performed. Students completed the modified School Sleep Habits Survey (SSHS), and the modified Electronic Media and Fatigue Questionnaire (EMFQ). Results:, Adolescents went to bed at 23:00 and 01:45 hours, and slept <7.5 and nearly 10.0 h on average, during weekdays and weekends respectively. Average electronic media exposure per day was about 3 h for television and 2.5 h for internet. Adolescents with a bedroom television went to bed later, had longer sleep latency and slept less than those without a bedroom television. Increased electronic media exposure and poor daytime sleep-related behaviours predicted later bedtime, longer sleep latency during weekdays and later wake-up time during weekends. Conclusion:, Poor sleep patterns in Israeli adolescents are related to excessive electronic media habits and daytime sleep-related problems. These findings raise a public health concern regarding lifestyle and functioning in young individuals. [source] The sleep of co-sleeping infants when they are not co-sleeping: Evidence that co-sleeping is stressfulDEVELOPMENTAL PSYCHOBIOLOGY, Issue 1 2002Melissa Hunsley Abstract Co-sleeping proponents consider the practice to be "natural" and a potential protection against sudden infant death syndrome (SIDS); others consider the practice of an infant sleeping in the parents' bed for prolonged periods at night to place an infant at risk for harm or death. For this study, co-sleeping was investigated from a different perspective, that is, as a significant early experience to investigate as it may have implications for the infant's development. The sleep of 101 normal, full-term infants was recorded nonintrusively in the home for 24 hr periods when they were 5 weeks and 6 months old. Infants were assigned to three groups: short-term co-sleepers, long-term co-sleepers, and non-co-sleepers. Their sleep states and wakefulness were compared at the two ages and over age. At 5 weeks and 6 months, the long-term co-sleeping infants differed significantly from the non-co-sleepers on a number of measures: At 5 weeks, they showed more quiet sleep and longer bouts of quiet sleep; and at 6 months, they also showed less active sleep, fewer arousals in active sleep, and less wakefulness. Each of these differences indicates a markedly lower arousal level in the long-term co-sleeping infants. This sleep pattern has been repeatedly found to be an indicator of stress. We infer that a major source of stress for these infants is the experience of sleep disturbance documented for infants when they were co-sleeping. Based on extensive evidence for long-term effects of early stress, we conclude that co-sleeping should have significant implications for infants' neurobehavioral development. © 2002 John Wiley & Sons, Inc.

J. Ferreira Recent case reports of ,sleep attacks' (SA) in patients with Parkinson's disease (PD) generated concerns about drug-induced daytime somnolence in this population. However, there are nearly no comparative data on sleep and vigilance problems between PD patients and normal controls. We performed a cross-sectional survey in PD patients and age-matched controls using a structured questionnaire on PD history, treatments, co-morbidity, activities of daily living, habits, exercise, sleep pattern, driving, pre-existing nocturnal problems, daytime somnolence, episodes of SA and the circumstances in which such episodes occurred. Daytime somnolence was also measured with the Epworth Sleepiness Scale (ESS) and sleep quality with the Pittsburgh Sleep Quality Index (PSQI). 176 PD patients and 174 controls were included. The same proportion of PD patients (27%) and controls (32%) reported episodes of SA, but these were more frequent in PD patients and occurred more frequently during situations requiring attention (10.8% vs. 1.7%, p<10,3). More PD patients had abnormal daytime somnolence (ESS) and poor sleeping quality (PSQI). The most consistent factor associated with SA was the duration of levodopa therapy and the predictive value of an abnormal ESS score was rather poor (40.7%). Abnormal daytime somnolence and poor sleep quality at night are more frequent in PD patients than in normals. However, SA are reported in both groups, although less frequently in the normals during activities that requires attention. [source] Brief Communications: An Analysis of Migraine Triggers in a Clinic-Based PopulationHEADACHE, Issue 8 2010Diane Andress-Rothrock MS Background., Many migraineurs report attack "triggers," but relatively few published data exist regarding the relative prevalences of individual triggers, variations related to gender, duration of migraine or migraine subtype, or the existence of any regional variations in the prevalences and distributions of triggers. Objective., We sought to determine the prevalence and types of migraine triggers in our clinic population, to determine what influence gender, migraine subtype, or duration of migraine might have on the prevalences and types of triggers reported and to compare our findings with data derived from surveys we previously had conducted involving 2 clinic-based populations and 1 general population sample from other regions of the USA. Methods., We evaluated 200 consecutive new migraine patients referred to our clinic. All patients specifically were queried as to whether they had noted any of 7 specific factors to serve consistently as migraine attack triggers and additionally were surveyed as to whether they might have "other" triggers not listed on the intake questionnaire. Among the other data collected and analyzed were age, gender, age at time of migraine onset, and migraine subtype (ie, episodic vs chronic). Actively cycling females who reported menses as a trigger were questioned as to whether their menstrual migraine (MM) attacks differed from their non-menstrual migraines and, if so, how they differed. Results., One hundred and eighty-two patients (91%) reported at least 1 migraine trigger, and 165 (82.5%) reported multiple triggers. The most common trigger reported (59%) was "emotional stress," followed by "too much or little sleep" (53.5%), "odors" (46.5%), and "missing meals" (39%). Females or subjects of either gender with chronic migraine were no more likely than males or subjects with episodic migraine to report triggers or multiple triggers. Similarly, longer exposure to migraine did not correlate with a higher likelihood of reporting a trigger or multiple triggers. Fifty-three (62%) of 85 actively cycling females reported menses as a trigger, and of the 51 with menstrually related migraine, 34 (67%) reported their MM to be more severe, more refractory to symptomatic therapy or of longer duration than their non-menstrual attacks; 13 (24.5%) of the 53 women with apparent MM reported their MM to be at least occasionally manifested as status migrainosus. The prevalence and type of triggers reported by this predominantly white female population were similar to those reported by clinic-based populations in San Diego, California and Mobile, Alabama, and in a population-based sample of Hispanics in San Diego County. Conclusions., A large majority of migraineurs report migraine attack triggers, and the triggers most commonly reported include emotional stress, a disrupted sleep pattern, and various odors. These findings do not appear to vary according to geographic region or race/ethnicity. Among the triggers, MM appears inclined to provoke headache that is more severe, less amenable to treatment, or longer in duration than headaches that occur at other times during the cycle.

Westenberg Summary Selective serotonin [5-hydroxytryptamine (5-HT)] reuptake inhibitors (SSRIs) and the 5-HT noradrenaline reuptake inhibitor, venlafaxine, are mainstays in treatment for depression. The highly specific actions of SSRIs of enhancing serotonergic neurotransmission appears to explain their benefit, while lack of direct actions on other neurotransmitter systems is responsible for their superior safety profile compared with tricyclic antidepressants. Although SSRIs (and venlafaxine) have similar adverse effects, certain differences are emerging. Fluvoxamine may have fewer effects on sexual dysfunction and sleep pattern. SSRIs have a cardiovascular safety profile superior to that of tricyclic antidepressants for patients with cardiovascular disease; fluvoxamine is safe in patients with cardiovascular disease and in the elderly. A discontinuation syndrome may develop upon abrupt SSRI cessation. SSRIs are more tolerable than tricyclic antidepressants in overdose, and there is no conclusive evidence to suggest that they are associated with an increased risk of suicide. Although the literature suggests that there are no clinically significant differences in efficacy amongst SSRIs, treatment decisions need to be based on considerations such as patient acceptability, response history and toxicity. [source] The DSM-IV ,minor depression' disorder in the oldest-old: prevalence rate, sleep patterns, memory function and quality of life in elderly people of Italian descent in Southern BrazilINTERNATIONAL JOURNAL OF GERIATRIC PSYCHIATRY, Issue 2 2002Flávio M. F. Xavier Abstract Objectives (1) To describe the prevalence of minor depression in a community-dwelling population aged 80 years and over. (2) To compare the sleep pattern, memory function and the prevalence rate of other psychiatric diagnoses between normal controls and subjects with minor depressive disorder. Design A random representative sample (sample,=,77 subjects/county population of oldest-old,=,219,35%) aged 80 years or more was selected from the county of Veranópolis in the Brazilian rural southern region. Of this group, eight subjects who met the DSM-IV criteria for minor depression, and 50 subjects without diagnosed delirium disorder, cognitive or affective problems were compared. Results The prevalence rate of minor depression was 12%. Subjects with this diagnosis were more likely to complain about sleep and memory problems than elderly people without any other affective disorder (major depression or dysthymic disorder). Otherwise, objective evaluation of these two areas, memory and sleep, did not show differences between the groups. Moreover, in terms of factors such as life satisfaction and some domains from the Short-form 36 Quality of Life Scale (SF-36), subjects with minor depression presented worse self-reported evaluations. Female gender was associated (p,=,0.01) with a more frequent presence of minor depression disorder, and those with this diagnosis were more likely to have co-morbidity with generalized anxiety disorder (p,=,0.007) when compared with elderly people without any depressive disorder. Conclusion In this study, minor depression has been significantly associated with lower life satisfaction and worse indexes of life quality. The results supported the current concept that minor depression is prevalent in later life, especially among the oldest-old. Subjects with minor depression had worse self-reported opinions about memory and sleep patterns, but when these variables were objectively measured, no meaningful differences could be determined by the research team. Female gender and the concurring presence of generalized anxiety disorder were both significantly associated with the presence of minor depression diagnosis. Copyright © 2002 John Wiley & Sons, Ltd. [source] Chronic Pain: Nursing Diagnosis or Syndrome?INTERNATIONAL JOURNAL OF NURSING TERMINOLOGIES AND CLASSIFICATION, Issue 4 2001Diná Almeida Lopes Monteiro Cruz PhD PROBLEM. To explore the existence of a pattern of nursing diagnoses that represents a chronic pain syndrome. METHODS. The nursing diagnoses of 68 oncologic and 46 nononcologic patients with chronic pain were submitted to univariate and multivariate analyses. Diagnoses ranked above the 75th percentile, without association with pain etiology, and presenting a pattern in cluster analyses and multidimensional scaling was accepted as possible components of chronic pain syndrome. FINDINGS. The possible components of chronic pain syndrome were disturbed sleep pattern,a constipation or risk for constipation, deficient knowledge,a impaired physical mobility, and anxiety/fear. CONCLUSIONS. Although a pattern of diagnoses has been proposed, confirmation will require further studies and the exploration of the clinical usefulness of the concept of chronic pain as a syndrome. PRACTICE IMPLICATIONS. Increased skill in the assessment and understanding of chronic pain can result in improved relief strategies. Douleur chronique: Diagnostic infirmier ou syndrome? PROBLÈME. Explorer l'existence d'un regroupement de diagnostics infirmiers représentant le syndrome de douleur chronique (SDC). MÉTHODES. Les diagnostics infirmiers présents chez 68 patients cancéreux et 46 patients non-cancéreux, souffrant de douleur chronique furent soumis à des analyses unidimensionnelles et multidimensionnelles. Les diagnostics qui furent retenus comme composantes possibles du SDC se situaient au dessus du 75e percentile, n'étaient pas associés à l'étiologie et représentaient un ensemble dans les analyses de regroupement et l'échelle multidimensionnelle. RÉSULTATS. Les composantes possibles du SDC furent perturbation des habitudes de sommeil, constipation ou risque de constipation, manque de connaissances, altération de la mobilité et anxiété/peur. CONCLUSIONS. Même si un schéma de diagnostics infirmiers a été proposé, il faudrait encore entreprendre plusieurs recherches et explorer l'utilité clinique du concept syndrome de douleur chronique, avant de confirmer la pertinence de ce syndrome.

[source] Fatigue in multiple sclerosis patientsJOURNAL OF CLINICAL NURSING, Issue 9 2009Mukadder Mollao Aim., This study aimed to describe fatigue and the factors that affect fatigue in people with multiple sclerosis. Background., Fatigue is the most common symptom and has the greatest effect on multiple sclerosis patients' activities of daily living. There is limited understanding of the level of fatigue experienced by people with multiple sclerosis, with research currently limited to other symptoms and problems related to multiple sclerosis. Design., This research was conducted as a descriptive survey. Methods., The study involved 120 people with multiple sclerosis. The data were collected with a Patient Questionnaire and a Visual Analogue Scale for Fatigue (VAS-F). Variance analysis, Mann,Whitney U -test and Kruskal,Wallis test were used in the data analysis. Results., All of the individuals in the sample experienced fatigue. Their fatigue was also affected by factors such as age, gender, education, marital status, number of children, occupation and duration of illness. In addition, the situations with the greatest effect on their fatigue were taking a hot bath/shower, hot/humid weather, stress, infection and other illnesses causing fever, disturbance in sleep pattern, increase in daily activities and exercise. Conclusions., Fatigue is a symptom that has a significant effect on the daily lives of people with multiple sclerosis. Accordingly, it is recommended that factors affecting fatigue in people with multiple sclerosis be evaluated and that education programmes directed at how to control these factors. Relevance to clinical practice., The determination of factors affecting fatigue is important for multiple sclerosis individuals' ability to cope with fatigue and keep it under control. To be able to accomplish this it is necessary for health care personnel, the family and friends to work together. [source] Disagreement between subjective and actigraphic measures of sleep duration in a population-based study of elderly persons,JOURNAL OF SLEEP RESEARCH, Issue 3 2008JULIA F. VAN DEN BERG Summary Sleep duration is an important concept in epidemiological studies. It characterizes a night's sleep or a person's sleep pattern, and is associated with numerous health outcomes. In most large studies, sleep duration is assessed with questionnaires or sleep diaries. As an alternative, actigraphy may be used, as it objectively measures sleep parameters and is feasible in large studies. However, actigraphy and sleep diaries may not measure exactly the same phenomenon. Our study aims to determine disagreement between actigraphic and diary estimates of sleep duration, and to investigate possible determinants of this disagreement. This investigation was embedded in the population-based Rotterdam Study. The study population consisted of 969 community-dwelling participants aged 57,97 years. Participants wore an actigraph and kept a sleep diary for, on average, six consecutive nights. Both measures were used to determine total sleep time (TST). In 34% of the participants, the estimated TST in the sleep diaries deviated more than 1 h from actigraphically measured TST. The level of disagreement between diary and actigraphic measures decreased with subjective and actigraphic measures of sleep quality, and increased with male gender, poor cognitive function and functional disability. Actigraphically measured poor sleep was often accompanied by longer subjective estimates of TST, whereas subjectively poor sleepers tended to report shorter TST in their diaries than was measured with actigraphy. We recommend, whenever possible, to use multiple measures of sleep duration, to perform analyses with both, and to examine the consistency of the results over assessment methods. [source] Abnormal movements in Rett syndrome are present before the regression period: A case studyMOVEMENT DISORDERS, Issue 15 2007Teresa Temudo MD Abstract The suspicion of a diagnosis of Rett syndrome (RTT) is based on clinical criteria that are often not present in the first two stages of the disease, as many of its symptoms will appear at a later age. This sometimes postpones the genetic diagnosis and an early clinical intervention. We present the case of 19-months-old girl who came to the consultation because of an arrest of psychomotor development noticed 5 months earlier without change in sleep pattern, behavior, or social communication. In the observation of 1 hour videotape, she presented subtle stereotypic movements of the face and hands as well as repetitive dystonic posturing of her limbs. A genetic test confirmed the diagnosis of RTT, showing a truncating mutation in the MECP2 gene (R270X). This case confirms that stereotypic movement anomalies, albeit infrequent and subtle, are already present before the regression stage and while maintaining prehension and that, in addition, repetitive dystonic postures may occur. Recognition of these early movement disorders will improve clinicians' ability to perform an earlier diagnosis of RTT. © 2007 Movement Disorder Society [source] T-type calcium channels: an emerging therapeutic target for the treatment of painDRUG DEVELOPMENT RESEARCH, Issue 4 2006Terrance P. Snutch Abstract It has become generally accepted that presynaptic high voltage,activated N-type calcium channels located in the spinal dorsal horn are a validated clinical target for therapeutic interventions associated with severe intractable pain. Low voltage,activated (T-type) calcium channels play a number of critical roles in nervous system function, including controlling thalamocortical bursting behaviours and the generation of spike wave discharges associated with slow wave sleep patterns. There is a growing body of evidence that T-type calcium channels also contribute in several ways to both acute and neuropathic nociceptive behaviours. In the one instance, the Cav3.1 T-type channel isoform likely contributes an anti-nociceptive function in thalamocortical central signalling, possibly through the activation of inhibitory nRT neurons. In another instance, the Cav3.2 T-type calcium channel subtype acts at the level of primary afferents in a strongly pro-nociceptive manner in both acute and neuropathic models. While a number of classes of existing clinical agents non-selectively block T-type calcium channels, there are no subtype-specific drugs yet available. The development of agents selectively targeting peripheral Cav3.2 T-type calcium channels may represent an attractive new avenue for therapeutic intervention. Drug Dev.

[source] Late-life insomnia: A reviewGERIATRICS & GERONTOLOGY INTERNATIONAL, Issue 3 2009Arne Fetveit Aging is associated with substantial changes in sleep patterns, which are almost always negative in nature. Typical findings in the elderly include a reduction in the deeper stages of sleep and a profound increase in the fragmentation of nighttime sleep by periods of wakefulness. The prevalence of specific sleep disorders increases with age, such as a phase advance in the normal circadian sleep cycle, restless legs syndrome, and obstructive sleep apnea, which is increasingly seen among older individuals and is significantly associated with cardio- and cerebrovascular disease as well as cognitive impairment. Elderly patients with sleep disturbances are often considered difficult to treat; yet, they are among the groups with the greatest need of treatment. Management of sleep disturbances begins with recognition and adequate assessment. Hypnotic drugs have clearly been shown to improve subjective and objective sleep measures in short-term situations, but their role in chronic insomnia still remains to be further defined by research evidence. Non-pharmacological treatments, particularly stimulus control and sleep restriction, are effective for conditioned aspects of insomnia and are associated with a stable, long-term improvement in sleep. This review delineates the common causes of disordered sleep in older individuals, and effective diagnostic approaches and treatments for these conditions. [source] Sleeping with baby: an internet-based sampling of parental experiences, choices, perceptions, and interpretations in a western industrialized contextINFANT AND CHILD DEVELOPMENT, Issue 4 2007J. J. McKenna Abstract Mothers and infants sleeping within proximity to each other (co-sleeping) represents normal, healthy, and expectable human behaviour, especially if mothers breastfeed. Yet, western health officials generally recommend against particularly one form of co-sleeping known as bedsharing. This study explores these issues and especially highlights parental accounts of their sleep practices, interpretations, and reflections based on detailed narratives or ,ethnohistories.' The sample involves a self-selected sub-group of over 200 mostly middle-class mothers from Canada, the United States, Australia, and Great Britain. Mothers report how and why they adopted co-sleeping practices, how satisfied they are (or were) with their decisions, and what benefits they think they or their infants derived from their co-sleeping practices. Also included in the reports are a surprisingly high number of parents who think they may have saved their infant's life by bedsharing, data heretofore never reported in the literature. The formulation of medical policies, we suggest, ultimately must be informed by a full understanding of how parents actually think about and subsequently structure their infant's sleep, what their goals and expectations are, and by an awareness of the emotional factors motivating parents to choose certain sleeping arrangements over others. The results reveal that many factors coalesce, often in unique ways, under unique circumstances, family by family, to determine where babies sleep and why. We conclude that sleeping arrangements are not solely determined by medically based recommendations, but also by the method of feeding, the particular needs of a particular infant, and the needs of mothers and fathers to get more sleep. While baby sleep locations and sleep patterns change in the first year of life, nighttime sleeping arrangements almost always reflect the nature of family values and the quality of social relationships at any given time. We conclude that these factors, alongside widely known independent SIDS risk factors, must also be acknowledged and respected if we are ever to achieve an effective and inclusive public health approach to the question of creating safe sleep environments for infants and children.

[source] "Ghosts in the Nursery:" Infant sleep and sleep-related cognitions of parents raised under communal sleeping arrangementsINFANT MENTAL HEALTH JOURNAL, Issue 3 2010Liat Tikotzky In an experiment of nature, a normal cohort of parents who were raised under communal sleeping arrangements (CSA) in Israeli kibbutzim are raising their infants at home under home-based family sleeping arrangements. The present study focused on exploring the links between the early sleep experiences of CSA parents and their present sleep-related beliefs and behaviors. In particular, the study assessed whether the cognitions of CSA parents regarding infant sleep differ from cognitions of parents who were raised under home-based family sleeping arrangements. Furthermore, parental soothing methods and infant sleep patterns were compared. One hundred forty-one families participated in this study. The children's ages ranged between 4.5 to 30 months. Parental cognitions were evaluated by two questionnaires. Infant sleep was assessed by a questionnaire and by daily parental reports. As expected, CSA parents were more likely than were control parents to: (a) interpret infant night wakings as a sign of distress and (b) actively soothe their infants at bedtime, co-sleep with them, and report more night wakings of their infants. These findings support the hypothesis that early childhood sleep-related experiences of parents ("Ghosts in the Nursery") influence their parental sleep-related cognitions that in turn affect infant sleep patterns. [source] Sleep patterns, sleep disturbances and sleepiness in retired Iranian eldersINTERNATIONAL JOURNAL OF GERIATRIC PSYCHIATRY, Issue 11 2009Seyed Kazem Malakouti Abstract Objectives Complaints of sleep disturbance increase with age and many studies have reported on the relationship of sleep problems to the greater use of health services, physical and mental morbidity, functional decline, and all causes of mortality. This study aimed to examine sleep patterns and sleep disturbances in Iranian elders and correlate their sleep quality to their health status. Methods Four hundred men and women, aged 60 years or older, were interviewed by trained interviewers regarding their physical and mental health status. The Pittsburghh Sleep Quality Index, the Epworth Sleepiness Scale (ESS), and a General Health Questionnaire (GHQ) were then administered to each participant. The data gathered were analyzed using ,2 -test, t -test, and one-way analysis of variance and logistic regression. Results The results indicated that the majority of participants (82.6%) suffered from poor sleep quality and approximately one-third (29.2%) experienced sleepiness during the daytime. Difficulty falling asleep (p,,,0.001) and maintaining sleep (p,,,0.01) and the feeling of being too hot at night (p,,,0.005) were significantly more prevalent in women, but men suffered more from leg twitching (p,,,0.01). Being female (OR,=,2.52), and having GHQ scores of more than 11 (OR,=,4.14) increased the risk of poor sleep quality considerably. Conclusion Promoting sleep hygiene education of elders in primary health care services are recommended. Copyright © 2009 John Wiley & Sons, Ltd.

Conclusion In this study, minor depression has been significantly associated with lower life satisfaction and worse indexes of life quality. The results supported the current concept that minor depression is prevalent in later life, especially among the oldest-old. Subjects with minor depression had worse self-reported opinions about memory and sleep patterns, but when these variables were objectively measured, no meaningful differences could be determined by the research team. Female gender and the concurring presence of generalized anxiety disorder were both significantly associated with the presence of minor depression diagnosis. Copyright © 2002 John Wiley & Sons, Ltd. [source] Evening Light Exposure: Implications for Sleep and DepressionJOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 4 2002Geralyn M. Wallace-Guy MA OBJECTIVES: To examine whether dim illumination in the evening is a factor in sleep disturbances of aging, depression, and circadian phase advance. DESIGN: One-week continuous recordings were made to record illumination exposure and to infer 24-hour sleep patterns from wrist activity. SETTING: Recordings took place during normal home and community activities. PARTICIPANTS: Complete data of 154 postmenopausal women, mean age 66.7, were selected from a larger study of participants in the Women's Health Initiative. MEASUREMENTS: Illumination in lux was averaged for 4 hours before bedtime and over 24 hours. Mood was measured using a brief eight-item screen. RESULTS: Illumination in the 4 hours before bedtime was quite dim: median 24 lux. Nevertheless, evening light exposure was not significantly related to sleep amount (in bed or out of bed) sleep efficiency, sleep latency, wake within sleep, or mood. In contrast, the overall amount of light throughout the 24 hours was negatively correlated with sleep latency, wake within sleep, and depressed mood. CONCLUSIONS: Low evening lighting does not appear to be a crucial factor in sleep and mood disturbances of aging, but overall lighting may contribute to these disturbances. [source] Objective investigation of the sleep,wake cycle in adults with intellectual disabilities and autistic spectrum disordersJOURNAL OF INTELLECTUAL DISABILITY RESEARCH, Issue 10 2006D. J. Hare Abstract Background Disturbances in circadian rhythm functioning, as manifest in abnormal sleep,wake cycles, have been postulated to be present in people with autistic spectrum disorders (ASDs). To date, research into the sleep,wake cycle in people with ASDs has been primarily dependant on third-party data collection. Method The utilization of non-invasive objective recording technologies such as actigraphy permits investigation of both sleep and circadian rhythm functioning in people with ASDs, together with the collection of data on daytime activity. Results Data were collected from 31 participants with intellectual disabilities living in supported community-based residential provision aged between 20 and 58 years, of whom 14 had an ASD. Analysis indicated that there were no significant differences in sleep patterns and circadian rhythm function between those participants with an ASD and those without. Conclusions The mean scores of the participants as a whole indicated abnormalities in the two key circadian rhythm parameters of interdaily stability and intradaily variability. The implications of these findings for both clinical practice and theory are discussed. [source] Leptin Uptake by Serotonergic Neurones of the Dorsal RapheJOURNAL OF NEUROENDOCRINOLOGY, Issue 6 2002M. C. Fernández-Galaz Abstract The effects of leptin on food intake, metabolism, sleep patterns and reproduction may be mediated, in part, by the midbrain serotonergic systems. Here, we report on the distribution of neurones that accumulate leptin in the raphe nuclei of male and female rats after intracerebroventricular administration of mouse recombinant leptin labelled with digoxigenin. Direct leptin-targeted cells were present in the periventricular grey, pontine and raphe nuclei. Confocal microscopy revealed that raphe neurones which accumulated leptin were predominantly serotonergic. The temporal pattern of leptin accumulation by raphe neurones showed a marked gender difference: 6 h after leptin administration, all male and female rats showed massive leptin binding in the dorsal raphe, while 30 min after leptin treatment, only 10% of male rats exhibited leptin-labelled cells in contrast to 50% of females. The present observations reveal that leptin can be selectively accumulated by serotonergic neurones in the raphe nuclei and that this mechanism is gender specific. These findings support the idea that the midbrain serotonergic system is an important mediator of the effects of leptin on brain function and may provide an explanation for gender differences in metabolism regulation and its coordination with higher functions of the brain. [source] A Selective Review of Maternal Sleep Characteristics in the Postpartum PeriodJOURNAL OF OBSTETRIC, GYNECOLOGIC & NEONATAL NURSING, Issue 1 2009Lauren P. Hunter ABSTRACT Objective: To determine the current knowledge of postpartum womens' sleep patterns, sleep disturbances, consequences of sleep disturbances, and known strategies for prevention in order to provide best practice recommendations for health care providers. Data Sources: A literature search from 1969 through February 2008 was conducted using the CINHL, Index of Allied Health Literature, Ovid, PsycINFO, and PubMed electronic databases in addition to reference lists from selected articles and other key references. Search terms included sleep, postpartum, sleep deprivation, and sleep disturbance. Study Selection: A critical review of all relevant articles from the data sources was conducted with attention to the needs of postpartum womens' sleep and implications for health care providers. Data Extraction: Literature was reviewed and organized into groups with similar characteristics. Data Synthesis: An integrative review of the literature summarized the current state of research related to sleep alterations in postpartum women. Conclusions: Postpartum women experience altered sleep patterns that may lead to sleep disturbances. The most common reasons for sleep disturbances are related to newborn sleep and feeding patterns. Although present, the relationships among sleep disturbance, fatigue, and depression in postpartum women lack clarity due to their ambiguous definitions and the variety of the studies conducted. Providers should encourage prenatal education that assists the couple in developing strategies for decreasing postpartum sleep deprivation. Alterations of in-hospital care and home care should be incorporated to improve the new family's sleep patterns. [source] symptom Experience in Women After HysterectomyJOURNAL OF OBSTETRIC, GYNECOLOGIC & NEONATAL NURSING, Issue 5 2001Kimberly H. Kim RN Objective: To review the literature addressing the symptom experience of women after hysterectomy. Data Sources: Computerized searches in MEDLINE and CINAHL, as well as texts and references cited in articles. Key concepts in the searches included hysterectomy, sleep disturbance and pain, hysterectomy and fatigue, hysterectomy, depression, and depressed mood. Study Selection: Articles and comprehensive works relevant to key concepts and published after 1970, with an emphasis on new findings from 1990 to 2000. Sixty-four citations were identified as useful to this review. Data Extraction: Data were organized under the following headings: women and hysterectomy, biopsychosocial perspectives, common symptoms after hysterectomy (pain, disturbed sleep, fatigue, depressed mood, anxiety), and significance of review (implications). Data Synthesis: Literature suggests that after a hysterectomy, women experience complications during the postoperative recovery period that may vary with the type of surgical procedure. During this period, the quantity and quality of sleep as well as other symptoms (pain, fatigue, anxiety, and depression) are influenced by various physiologic, psychologic, and social factors. Despite limited evidence that sleep problems may occur frequently during the recovery period, only a few researchers have systematically examined sleep patterns in women after hysterectomy. None of these studies, however, used objective sleep measures or examined multiple dimensions of these women's lives. Conclusions: This review conceptualized the women's symptom experience as the experience of specific symptoms (pain, sleep disturbance, fatigue, depressed mood, and anxiety) that were influenced by biopsychosocial factors. [source] Puberty-Dependent Sleep Regulation and Alcohol Use in Early AdolescentsALCOHOLISM, Issue 9 2010Sara Pieters Background:, Research has shown a bi-directional relation between alcohol use and sleep regulation in adults. Much less is known about this association in early adolescents, while profound puberty-dependent transitions regarding sleep patterns take place in early adolescence. Moreover, puberty has been associated with an increase in alcohol use of adolescents. Methods:, In this study, we investigated the associations between pubertal development, sleep preference, sleep problems, and alcohol use in 431 early adolescents (mean age: 13.66). Second, it was studied whether the associations changed when controlling for adolescent internalizing and externalizing problems. Furthermore, we included gender as a moderator on all the associations. Results:, Results showed that pubertal development was positively associated with sleep problems and more evening-type tendencies (e.g., favoring later bedtimes), which in turn were positively related to alcohol use. Underlying psychopathology, gender and educational level did not change these relationships. Conclusions:, From this study, it can be concluded that both puberty and sleep regulation are important factors in explaining alcohol use in early adolescence. [source] Circadian preference, sleep and daytime behaviour in adolescenceJOURNAL OF SLEEP RESEARCH, Issue 3 2002Flavia Giannotti Summary The aim of this study was to determine the relationship between circadian preferences, regularity of sleep patterns, sleep problems, daytime sleepiness and daytime behaviour. As a part of an epidemiological survey on sleep in a representative sample of Italian high-school students, a total of 6631 adolescents, aged 14.1,18.6 years, completed the School Sleep Habits Survey, a comprehensive questionnaire including items regarding sleep, sleepiness, substance use, anxiety and depressed mood, use of sleeping pills, school attendance and a morningness/eveningness scale. The sample consisted of 742 evening-types (315 males and 427 females; mean age 17.1 years) and 1005 morning-types (451 males and 554 females; mean age 16.8 years). No significant sex differences were found for morningness/eveningness score. Eveningness was associated with later bedtime and wake-up time, especially on weekends, shorter time in bed during the week, longer weekend time in bed, irregular sleep,wake schedule, subjective poor sleep. Moreover, evening types used to nap more frequently during school days, complained of daytime sleepiness, referred more attention problems, poor school achievement, more injuries and were more emotionally upset than the other chronotype. They referred also greater caffeine-containing beverages and substances to promote sleep consumption. Our results suggest that circadian preference might be related not only to sleep pattern, but also to other adolescent behaviours. [source] The effect of acid suppression on sleep patterns and sleep-related gastro-oesophageal refluxALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 2 2005W. C. Orr Summary Background :,Several studies have demonstrated that night-time gastro-oesophageal reflux affects sleep quality, and thereby impairs daytime functioning. Aim :,To determine whether treatment with a proton-pump inhibitor (rabeprazole) would improve both objective and subjective measures of sleep. Methods :,Individuals with complaints of significant gastro-oesophageal reflux disease were studied by polysomnography and 24-h pH monitoring on two separate nights. On one occasion, participants received 20 mg rabeprazole b.d., and on another they received placebo. Both study conditions were preceded by a week of treatment with either rabeprazole or placebo. The order of treatments was randomized. Results :,Rabeprazole significantly reduced overall acid reflux, but it did not significantly reduce night-time acid contact. Rabeprazole treatment significantly improved subjective indices of sleep quality. There were no significant differences on objective measures of sleep between placebo and rabeprazole treatment. Conclusions :,Consistent with other studies of pharmacological treatments for gastro-oesophageal reflux, subjective measures of sleep improved with heartburn medication but objective measures were not affected. [source] Differences in electroencephalogram power densities between genuine narcolepsy and secondary narcolepsyPSYCHIATRY AND CLINICAL NEUROSCIENCES, Issue 3 2000Hiroshi Honma MD Abstract Diagnosing narcolepsy is not always simple. Some patients secondarily show narcoleptic tetrad through irregular sleep patterns or psychotic diseases. The power densities of daytime electroencephalograms in genuine narcolepsy and secondary narcolepsy were analysed and compared. Electroencephalogram power densities for a 6.5-h period after waking in genuine narcoleptic patients were lower than those of secondary narcoleptic patients in the 11.0,12.5 Hz bands. Arousal levels may be lower in genuine narcoleptic patients than in secondary narcoleptic patients. Spectral analysis may be useful in clarifying differences between the two groups.
