Frequent sputum production is associated with disturbed night's rest and impaired sleep quality in patients with COPD.

PurposeIn this study, we measured night’s rest parameters measured with an accelerometer and sleep quality in mild to very severe patients with COPD. Furthermore, our aim was to investigate the association between night’s rest parameters and clinical variables and the association between sleep quality and quality of life or health status.MethodsMild to very severe COPD patients were recruited from general practitioners and outpatient clinics of general hospitals to participate in a cross-sectional study on physical activity in patients with COPD. A total of 103 patients (mean age 65 years, 67 % male) wore the accelerometer during night’s rest for at least four nights and were included in the analyses.ResultsNo significant associations were found between objectively measured body movements during night’s rest or subjective sleep quality and lung function, dyspnoea severity, body composition and physical activity during the day. Patients with frequent sputum production during the day had a higher number of sitting transitions during the night (5.3 vs 4.3 sitting transitions) and more frequently got out of bed compared to patients who hardly ever produced sputum during the day (1.0 vs 0.8 times per night). Furthermore, these patients also reported worse sleep quality (Pittsburgh sleep quality index (PSQI) score 4 vs 3).ConclusionsOur results indicate that objectively measured body movements during night’s rest like body postures and transitions are not related to sleep quality in patients with COPD. We did find an association between frequent sputum production and disturbances during night’s rest and sleep quality. Future studies should investigate whether the treatment of mucus hypersecretion leads to improved night’s rest.

Positive affect and pain: mediators of the within-day relation linking sleep quality to activity interference in fibromyalgia.

Fibromyalgia (FM) is a chronic pain condition often resulting in functional impairments. Nonrestorative sleep is a prominent symptom of FM that is related to disability, but the day-to-day mechanisms relating the prior night's sleep quality to next-day reports of disability have not been examined. This study examined the within-day relations among early-morning reports of sleep quality last night, late-morning reports of pain and positive and negative affect, and end-of-day reports of activity interference. Specifically, we tested whether pain, positive affect, and negative affect mediated the association between sleep quality and subsequent activity interference. Data were drawn from electronic diary reports collected from 220 patients with FM for 21 consecutive days. The direct and mediated effects at the within-person level were estimated with multilevel structural equation modeling. Results showed that pain and positive affect mediated the relation between sleep quality and activity interference. Early-morning reports of poor sleep quality last night predicted elevated levels of pain and lower levels of positive affect at late-morning, which, in turn, predicted elevated end-of-day activity interference. Of note, positive affect was a stronger mediator than pain and negative affect was not a significant mediator. In summary, the findings identify 2 parallel mechanisms, pain and positive affect, through which the prior night's sleep quality predicts disability the next day in patients with FM. Furthermore, results highlight the potential utility of boosting positive affect after a poor night's sleep as one means of preserving daily function in FM.

“Do I really need a nap?”: The role of sleep science in informing sleep practices in early childhood education and care settings.

A compelling body of studies identifies the importance of sleep for children’s learning, behavioral regulation, and health. These studies have primarily focused on nighttime sleep or on total sleep duration. The independent contribution of daytime sleep, or napping, in childhood is an emerging research focus. Daytime sleep is particularly pertinent to the context of early childhood education and care (ECEC) where, internationally, allocation of time for naps is commonplace through to the time of school entry. The biological value of napping varies with neurological maturity and with individual circumstance. Beyond the age of 3 years, when monophasic sleep patterns become typical, there is an increasing disjuncture between children’s normative sleep requirements and ECEC practice. At this time, research evidence consistently identifies an association between napping and decreased quality and duration of night sleep. We assess the implications of this evidence for educational practice and health policy. We identify the need to distinguish the functions of napping from those of rest, and assert the need for evidence-based guidelines on sleep–rest practices in ECEC settings to accommodate individual variation in sleep needs. Given both the evidence on the impact of children’s nighttime sleep on long-term trajectories of health and well-being and the high rates of child attendance in ECEC programs, we conclude that policy and practice regarding naptime have significant implications for child welfare and ongoing public health.

Sleep Problems Exacerbate the Emotional Consequences of Interpersonal Rejection

Previous literature has established a link between experiences of interpersonal rejection and hurt feelings. However, little research has examined intra-individual differences in sensitivity to rejection. We address this gap in research through examining daily fluctuations in sensitivity to rejection and poor sleep as a risk factor for these increases in sensitivity. Participants were 77 heterosexual college-student couples who completed daily diary measures of previous night's sleep quality, as well as daily experiences of rejection and hurt feelings over a period of 7 days. During this time, participants also wore an actigraph in order to obtain objective measures of sleep quality and duration. The association between perceived rejection and hurt feelings was manifest only under conditions of poor sleep (lower quality and quantity). Results highlight the importance of sleep for coping with daily interpersonal events and improve understanding of intra-individual differences in sensitivity to rejection.

The Bidirectional Relationship Between Pain Intensity and Sleep Disturbance/Quality in Patients With Low Back Pain

This study investigated the bidirectional relationship between the intensity of low back pain (LBP) and sleep disturbance. Further, the study aimed to determine whether any relationship is dependent on pain duration, symptoms of depression and anxiety, and the method of sleep assessment (subjective vs. objective). Eighty patients with LBP completed a sleep diary. A subgroup of 50 patients additionally wore an electronic device (Armband) to measure sleep for 7 consecutive days. Pain intensity was assessed twice daily using a sleep diary. Depression and anxiety symptoms were assessed at baseline using the Depression Anxiety Stress Scale questionnaire. Generalized estimating equations (GEE) with an exchangeable correlation structure were used to examine the relationship between day-time pain intensity and sleep. The GEE analysis showed that a night of poor sleep quality, difficulty falling sleep (assessed by the sleep diary), waking after sleep onset, and low sleep efficiency (assessed by the sleep diary and Armband) were followed by a day with higher pain intensity. Further, a day with higher pain intensity was associated with a decrease in the subsequent night's sleep quality, an increase in sleep latency (assessed by the sleep diary), waking after sleep onset (assessed by both measures), and low sleep efficiency (assessed by the Armband). The findings demonstrate that there is a bidirectional relationship between sleep and pain intensity in patients with LBP. The relationship is independent of pain duration and baseline symptoms of depression and anxiety and somewhat dependent on the method of sleep measurement (sleep diary or Armband). Future research is needed to determine whether targeting sleep improvement in patients with LBP contributes to pain reduction.

Sleep and circadian rhythms in hospitalized patients with decompensated cirrhosis: effect of light therapy.

Patients with liver cirrhosis often exhibit sleep-wake abnormalities, which are, at least to some extent, circadian in origin. A relatively novel non-pharmacological approach to circadian disruption is appropriately timed bright light therapy. The aims of this pilot study were to investigate sleep-wake characteristics of a well-characterized population of inpatients with cirrhosis, and to evaluate the efficacy of bright light therapy in the hospital setting. Twelve consecutive inpatients with cirrhosis underwent complete sleep-wake assessment, to include qualitative and semi-quantitative (actigraphic) indices of night-time sleep quality, daytime sleepiness, diurnal preference, habitual sleep timing, quality of life, mood and circadian rhythmicity [i.e. urine collections for measurement of the melatonin metabolite 6-sulphatoxymelatonin (aMT6s)]. Patients showed extremely impaired night sleep quality (Pittsburg Sleep Quality Index global score: 16.3 ± 2.1) and daytime sleepiness was common (Epworth Sleepiness Scale: 8.3 ± 3.2). Five patients were randomly assigned to a single room in which lighting was controlled in relation to timing, spectral composition and intensity (lights on at 06:30 and off at 22:30, blue-enriched, more intense light in the morning, red-enriched, less intense light in the afternoon/evening); the others stayed in identical rooms with standard lighting. Sleep diaries revealed poor sleep quality, prolonged sleep latency (67 ± 138 min) and a reduced sleep efficiency (69 ± 21%). These features were confirmed by actigraphy (sleep efficiency: 71 ± 13%; fragmentation index: 55 ± 15%). Quality of life was globally impaired, and mood moderately depressed (Beck Depression Inventory: 19.4 ± 7.9). Seven patients underwent serial urine collections: no circadian aMT6s rhythm was detected in any of them, neither at baseline, nor during the course of hospitalization in either room (n = 4). In conclusion, sleep and circadian rhythms in hospitalized, decompensated patients with cirrhosis are extremely compromised. Treatment with bright light therapy did not show obvious, beneficial effects, most likely in relation to the severity of disturbance at baseline.

Stress, sleep, depression and dietary intakes among low-income overweight and obese pregnant women.

This study investigated the mediating roles of sleep and depression on the relationships between stress, fat intake, and fruit and vegetable intake among low-income overweight and obese pregnant women by trimesters. Participants (N = 213) completed a self-administered survey including stress (exogenous variable), depression, sleep (mediators), fat intake, and fruit and vegetable intake (endogenous variables). Path analysis was performed to compare mediation effects among pregnant women in each trimester. Consistently across three trimesters, stress was related to depression but not sleep duration, night time sleep disturbance, sleep quality, sleep latency or fat intake. Sleep duration was not associated with depression. Depending on trimester, night time sleep disturbance, sleep quality, and sleep latency were related to depression; night time sleep disturbance and depression affected fat intake; stress influenced fruit and vegetable intake. Sleep duration, sleep disturbance, sleep quality, sleep latency and depression did not mediate the relationships between stress, fat intake, and fruit and vegetable intake in the second and third trimesters. However, depression mediated the relationship between stress and fat intake in the first trimester. Stress management interventions may help low-income overweight and obese pregnant women decrease depressive symptoms and therefore contribute to overall nutritional health.

A prospective 10-year follow-up polygraphic study of patients treated with a mandibular protruding device

This 10-year follow-up prospective study aimed to evaluate the effects of treatment with a mandibular protruding device (MPD) on respiratory parameters and subjective symptoms in patients with obstructive sleep apnea (OSA) or snoring. Seventy-seven consecutive patients diagnosed with OSA or snoring were treated with an MPD. At baseline and the 10-year follow-up, a polygraphic examination and questionnaires on sleep quality were administrated and weight, and neck size was measured. At the 10-year follow-up, we examined 64 of the 77 patients and recorded their current treatment (45 MPD, 9 continuous positive airway pressure (CPAP), and 10 no treatment). For MPD patients, 89% reported MPD use every night and 9% several nights a week. Compared to baseline, MPD users with OSA had a significantly decreased oxygen desaturation index (ODI) (p = 0.006) and increased lowest arterial oxygen saturation, SaO2 nadir (p = 0.007) after 10years. MPD treatment was successful for 70% of OSA patients, yet 89% subjectively considered themselves cured, indicating overestimation of the treatment effect. OSA patients who responded to treatment maintained baseline weight and neck size, while these increased for non-responders. Of the baseline snorers still using an MPD, 93% maintained an ODI value of <5. All CPAP users had an ODI value of <5. Both OSA and snorers using an MPD had significantly fewer self- and relative reports of snoring, apnea, daytime tiredness, and poor night sleep quality (p < 0.001). MPD treatment is well tolerated and effective in a long-term, 10-year perspective. Weight gain may jeopardize MPD effects. Both patients and relatives reported significantly less snoring and fewer periods of apnea.

Placebo sleep affects cognitive functioning.

The placebo effect is any outcome that is not attributed to a specific treatment but rather to an individual's mindset (Benson & Friedman, 1996). This phenomenon can extend beyond its typical use in pharmaceutical drugs to involve aspects of everyday life, such as the effect of sleep on cognitive functioning. In 2 studies examining whether perceived sleep quality affects cognitive functioning, 164 participants reported their previous night's sleep quality. They were then randomly assigned to 1 of 2 sleep quality conditions or 2 control conditions. Those in the "above average" sleep quality condition were informed that they had spent 28.7% of their total sleep time in REM, whereas those in the "below average" sleep quality condition were informed that they had only spent 16.2% of their time in REM sleep. Assigned sleep quality but not self-reported sleep quality significantly predicted participants' scores on the Paced Auditory Serial Addition Test and Controlled Oral Word Association Task. Assigned sleep quality did not predict participants' scores on the Digit Span task, as expected, nor did it predict scores on the Symbol Digit Modalities Test, which was unexpected. The control conditions showed that the findings were not due to demand characteristics from the experimental protocol. These findings supported the hypothesis that mindset can influence cognitive states in both positive and negative directions, suggesting a means of controlling one's health and cognition.

Effect of Ecofriendly Microencapsulated Textile Products In Joint Pain and Aesthematic Respondents

The study was conducted to develop aromtheraputic textile products for joint pains/ asthma. Fabric treated with eco-friendly microcapsules of eucalyptus, jasmine, lemon and pine oil respectively were used for the treatment of respondents. Knee caps, gloves, Pillow covers and handkerchieves were made joint & ashtetic respectively for the respondents out of cotton fabric. Respondents suffering were undergone for the wear trail of two months. To get the results through interview schedule data collected. The results showed that the developed products had a positive effect on the emotional state of the respondents (87%), improved in quality of night sleep (95%), out door activities (67%) and reduced medicine in take (50%). The results also showed soothing effect on the skin of the respondents after using these aromatherapic textiles. Therefore, it was recommended that the aromatherapic textile products made with eco- friendly chemicals like betacyclodextrine as binder and chitosin as sheath along with different essential oils in core can be used for developing products. These products retain their fragrance for at least 20 washings ifwashed under controlled conditions.

Evaluation of oral iron supplementation in pediatric maintenance insomnia

Iron deficiency anemia (IDA) is a very common problem that increases spontaneous nocturnal restless motor activity and night wakings during sleep. IDA has been linked to cognitive problems such as poor attention, lack of concentration and learning difficulties. We conducted a prospective and open-label study of children and adolescents with IDA (defined by serum ferritin under 50 ng/ml, iron deficiency and/or anemia) and maintenance insomnia (IM) with nocturnal restless activity and night waking, treated with oral iron supplementation to evaluate the efficacy of this treatment, administered during the course of clinical care. The study included 116 children and adolescents (67 boys and 49 girls) with IDA and MI who visited the Pediatric Sleep Unit. Sleep quality was assessed with PSQ, SDSC questionnaires and CGI-C. Blood tests were made in all patients; night-time polysomnography was performed in 46 cases. After IDA and MI diagnosis, oral iron supplementation (ferric sulfate) was administered to all children and adolescents (4 mg/kg/day; 325 mg/day after 12 yo). Blood parameters and sleep quality were reassessed 3–6 months after. Patient age at onset of symptoms ranged from 0.5 to 17 years (mean ± SD, 5.4 ± 4.1) and 2 groups were observed: with (I+) or without improvement. (I−). A positive family history of insomnia, PLM o RLS was recognized in 40 patients and RLS was found in 13 subjects (no differences related with improvement) but PLMD was more prevalent in I+ group (28% vs 13%; p = 0.09). Serum ferritin level before therapy was 5–96 ng/ml (30.3 ± 18.2) and oral iron supplementation was reported to be effective in 83.6% patients (85% highly effective, CGI-C 1 or 2). Lower serum iron levels were seen in patients with higher apnea/hipopnea index ( p : 0.077). Though serum ferritin and iron concentrations were not improvement related (I+ vs I−, p > 0.05), ferritin ”in range” (below 50 ng/ml but higher that lower normal limit) was strongly related with clinical improvement ( p = 0.001). The onset of treatment effect was approximately 3 months. Supplemental iron was consistently associated with less night waking and sleep quality improvement. Iron treatment has demonstrated to be effective in pediatric MI and IDA. We thank Dr. J. García-Sicilia (Department of Pediatrics) for helping us in coordinating Hospital Sleep Unit with Primary Care physicians.

Correlations between night eating, sleep quality, and excessive daytime sleepiness in a severely obese UK population

ObjectiveThe relationships between night eating, poor sleep quality, and obesity-related comorbidity in a severely obese UK clinic population is unknown. We used validated tools to identify prevalence and to explore this relationship. MethodsConsecutive consenting clinic attendees completed the Pittsburgh Sleep Quality Index (PSQI), Epworth Sleepiness Score (ESS), and Night Eating Questionnaire (NEQ) to identify sleep quality, excessive daytime sleepiness (EDS) (a surrogate marker for suspected obstructive sleep apnea [OSA]), and night eating, respectively. Proportions of individuals above and below tool cutoff points were compared. Pearson product moment correlation coefficients examined relationships between total scores. ResultsReported prevalence from 144 participants (mean body mass index [BMI] 46.9 [9.5]kg/m2; age 44.6 [12.1]years; 68% women) had poor sleep quality (73.0%), suspected OSA (30.8%), and night-eating behavior (2.8%). The strongest correlation between PSQI and NEQ scores (r=0.54; P<.001) was undiminished after controlling for EDS. Although significantly correlated, PSQI and ESS scores (r=0.31; P<.001) reduced after controlling for night eating (r=0.21; P=.02). Correlation between NEQ and ESS scores (r=0.26; P=.002) was smaller and nonsignificant after controlling for sleep quality (r=0.12; P=.18). ConclusionsPoor sleep quality is common in severe obesity, though night eating is rare. The association between poor sleep quality and night eating is not influenced by the presence of EDS.

Night diapers use and sleep in children with enuresis

ObjectiveWe aimed to assess the association between night diapers use and sleep quality of school-aged children with enuresis. MethodsThe sleep patterns of 72 school-aged children (ages 6–9y) with enuresis referred to a clinic specializing in bladder disorders and 63 healthy control children were assessed. Sleep measures were derived from four to five monitoring nights of actigraphy and daily logs. ResultsIn comparison to controls, children with enuresis who did not wear night diapers had poorer sleep quality as reflected by both actigraphic measures (more activity during sleep and shorter periods of continuous sleep) and one reported measure (lower sleep quality). However, no differences were found on any of the sleep measures between children with enuresis wearing night diapers and controls. The reported sleep quality of all children with enuresis with and without night diapers was lower than controls. ConclusionsOur results suggest that sleep patterns of school-aged children with enuresis who do not wear night diapers are impaired, and the sleep quality of children using night diapers is similar to those of healthy children. Thus, clinicians and healthcare providers should consider recommending sleeping with night diapers for untreated children with enuresis, based on its positive impact on sleep.

In search of objective components for sleep quality indexing in normal sleep

The main goal of this study was to investigate to what extent polysomnographic (PSG) recordings of nocturnal human sleep can provide information about sleep quality in terms of correlation with a set of daytime measures. These measures were designed with the aim of comprising selected quality of night sleep and consist of subjective sleep quality ratings, neuropsychological tests and physiological parameters. First, a factor analysis model was applied to the large number of daytime measures of sleep quality in order to detect their latent structure. Secondly, in addition to the gold standard sleep staging method to arrive at variables about sleep architecture from PSG, we applied a recently developed continuous sleep representation by considering the probabilistic sleep model (PSM) describing the microstructure of sleep. Significant correlations between sleep architecture and daytime variables of sleep quality were found. Both the factor analysis and the PSM helped maximize the information about this relationship.

A tryptophan-rich breakfast and exposure to light with low color temperature at night improve sleep and salivary melatonin level in Japanese students

BackgroundEpidemiological studies in Japan have documented an association between morning type and a tryptophan-rich breakfast followed by exposure to sunlight in children. The association may be mediated by enhanced melatonin synthesis, which facilitates sleep at night. However, melatonin is inhibited by artificial light levels with high color-temperature common in Japanese homes at night. In this study, we investigated whether a combination of tryptophan-rich breakfast and light with low color-temperature at night could enhance melatonin secretion and encourage earlier sleep times.MethodsThe intervention included having breakfast with protein- and vitamin B6 - rich foods and exposure to sunlight after breakfast plus exposure to incandescent light (low temperature light) at night (October-November, 2010). The participants were 94 members of a university soccer club, who were divided into 3 groups for the intervention (G1: no intervention; G2: asked to have protein-rich foods such as fermented soybeans and vitamin B6-rich foods such as bananas at breakfast and sunlight exposure after breakfast; G3: the same contents as G2 and incandescent light exposure at night). Salivary melatonin was measured around 11:00 p.m. on the day before the beginning, a mid-point and on the day before the last day a mid-point and on the last day of the 1 month intervention.ResultsIn G3, there was a significantly positive correlation between total hours the participants spent under incandescent light at night and the frequency of feeling sleepy during the last week (p = 0.034). The salivary melatonin concentration of G3 was significantly higher than that of G1 and G2 in combined salivary samplings at the mid-point and on the day before the last day of the 1 month intervention (p = 0.018), whereas no such significant differences were shown on the day just before the start of the intervention (p = 0.63).ConclusionThe combined intervention on breakfast, morning sunlight and evening-lighting seems to be effective for students including athletes to keep higher melatonin secretion at night which seems to induce easy onset of the night sleep and higher quality of sleep.
