1 Review Sleep disorders in patients with multiple sclerosis. 2010

Brass, Steven D / Duquette, Pierre / Proulx-Therrien, Joëlle / Auerbach, Sanford. ·Co-Director of Sleep Medicine, Department of Neurology, UC Davis School of Medicine, 4860 Y Street, Suite 0100, Sacramento, CA 95817, USA. steven.brass@ucdmc.ucdavis.edu ·Sleep Med Rev · Pubmed #19879170.

ABSTRACT: Patients with multiple sclerosis (MS) often have unrecognized sleep disorders at higher frequency than the general population. Sleep disorders such as sleep disordered breathing, insomnia, REM sleep behavior disorder, narcolepsy and restless legs syndrome have all been reported in the MS population. Notably, the most common symptom of MS is "fatigue," which itself has been correlated with sleep disturbances. Sleep disorders may impact the quality of life of the MS patient population. This paper reviews the association of sleep disorders with MS, and discusses the association of sleep disruption with MS fatigue.

2 Review Sleep in hospitalized medical patients, part 2: behavioral and pharmacological management of sleep disturbances. 2009

Young, Julie S / Bourgeois, James A / Hilty, Donald M / Hardin, Kimberly A. ·Department of Psychiatry and Behavioral Sciences, University of California, Davis, Sacramento, California 95817, USA. julie.young@ucdmc.ucdavis.edu ·J Hosp Med · Pubmed #19140196.

ABSTRACT: BACKGROUND: As described in Part 1 of this article, multiple factors lead to disrupted sleep in hospitalized medical patients. Recognizing and addressing these factors can help clinicians more effectively manage patients' sleep complaints. METHODS: A PubMed search was conducted by cross-referencing the terms "sleep deprivation," "insomnia," and "sleep"; "hospitalized," "acutely ill," and "critically ill"; and "medication," "drugs," "hypnotics," "benzodiazepines," and "sedatives." The search was limited to English-language articles published between 1997 and 2008. Subsequent PubMed searches were performed to clarify the data described in the initial search. RESULTS: Few articles addressed the topic of the assessment and management of sleep problems in hospitalized medical patients. In Part 2, we propose an evaluation and treatment algorithm that includes recommendations regarding the use of nonpharmacologic and pharmacologic therapies as clinicians consider relevant clinical data. The algorithm is accompanied by 5 tables that include pertinent and practical information to assist clinicians as they manage their inpatients' sleep complaints. CONCLUSIONS: Assessment of a sleep complaint should include a review of factors that could exacerbate patients' sleep. The treatment could then focus on ameliorating these factors, and the judicious use of nonpharmacologic strategies and psychopharmacologic agents.

ABSTRACT: PURPOSE: Epidemiological studies suggest that short sleep duration and poor sleep quality may increase breast cancer risk. However, whether sleep is associated with breast tumor aggressiveness characteristics has largely been unexplored. METHODS: The study included 4171 non-Hispanic whites (NHW) and 235 African Americans (AA) diagnosed with incident, primary, invasive breast cancer in the Women's Health Initiative (WHI) Observational Study (1994-2013). We used logistic regression to examine the association of baseline sleep (sleep duration, sleep quality, WHI Insomnia Rating Scale) with tumor grade, stage, hormone receptor status, HER2 status. RESULTS: In NHW, women who reported 6 h of sleep/night were more likely to have tumors classified as regional/distant stage at diagnosis compared to women who slept 7-8 h/night (adjusted odds ratio (OR): 1.25, 95% confidence interval (CI): 1.05-1.48). AA women who reported their typical night's sleep as 'average quality' or 'restless or very restless sleep' were more likely to be diagnosed with triple-negative tumors than those who reported 'sound or restful' sleep (adjusted ORs: 2.91 (1.11, 7.63) and 3.74 (1.10, 12.77), respectively). CONCLUSIONS: Our findings provide indications that aspects of sleep (sleep duration and quality), partially modifiable health behaviors, may be associated with development of aggressive tumor characteristics in postmenopausal women. The role of these sleep attributes may differ for NHW and AA women; however, further study in robust, racial diverse samples is needed. This study provides evidence that facets of sleep behavior are associated with the development of aggressive tumor features and these associations differ by race.

4 Article Neural Reward Processing Mediates the Relationship between Insomnia Symptoms and Depression in Adolescence. 2016

Casement, Melynda D / Keenan, Kate E / Hipwell, Alison E / Guyer, Amanda E / Forbes, Erika E. ·University of Pittsburgh, Pittsburgh, PA. · University of Chicago, Chicago, IL. · University of California, Davis, Davis, CA. ·Sleep · Pubmed #26350468.

ABSTRACT: STUDY OBJECTIVES: Emerging evidence suggests that insomnia may disrupt reward-related brain function-a potentially important factor in the development of depressive disorder. Adolescence may be a period during which such disruption is especially problematic given the rise in the incidence of insomnia and ongoing development of neural systems that support reward processing. The present study uses longitudinal data to test the hypothesis that disruption of neural reward processing is a mechanism by which insomnia symptoms-including nocturnal insomnia symptoms (NIS) and nonrestorative sleep (NRS)-contribute to depressive symptoms in adolescent girls. METHOD: Participants were 123 adolescent girls and their caregivers from an ongoing longitudinal study of precursors to depression across adolescent development. NIS and NRS were assessed annually from ages 9 to 13 years. Girls completed a monetary reward task during a functional MRI scan at age 16 years. Depressive symptoms were assessed at ages 16 and 17 years. Multivariable regression tested the prospective associations between NIS and NRS, neural response during reward anticipation, and the mean number of depressive symptoms (omitting sleep problems). RESULTS: NRS, but not NIS, during early adolescence was positively associated with late adolescent dorsal medial prefrontal cortex (dmPFC) response to reward anticipation and depressive symptoms. DMPFC response mediated the relationship between early adolescent NRS and late adolescent depressive symptoms. CONCLUSIONS: These results suggest that NRS may contribute to depression by disrupting reward processing via altered activity in a region of prefrontal cortex involved in affective control. The results also support the mechanistic differentiation of NIS and NRS.

ABSTRACT: OBJECTIVE: We examined the associations of symptoms of sleep-disordered breathing (SDB), which was defined as loud snoring, stopping breathing for a while during sleep, and daytime sleepiness, and insomnia with glucose metabolism and incident type 2 diabetes in older adults. RESEARCH DESIGN AND METHODS: Between 1989 and 1993, the Cardiovascular Health Study recruited 5,888 participants ≥65 years of age from four U.S. communities. Participants reported SDB and insomnia symptoms yearly through 1989-1994. In 1989-1990, participants underwent an oral glucose tolerance test, from which insulin secretion and insulin sensitivity were estimated. Fasting glucose levels were measured in 1989-1990 and again in 1992-1993, 1994-1995, 1996-1997, and 1998-1999, and medication use was ascertained yearly. We determined the cross-sectional associations of sleep symptoms with fasting glucose levels, 2-h glucose levels, insulin sensitivity, and insulin secretion using generalized estimated equations and linear regression models. We determined the associations of updated and averaged sleep symptoms with incident diabetes in Cox proportional hazards models. We adjusted for sociodemographics, lifestyle factors, and medical history. RESULTS: Observed apnea, snoring, and daytime sleepiness were associated with higher fasting glucose levels, higher 2-h glucose levels, lower insulin sensitivity, and higher insulin secretion. The risk of the development of type 2 diabetes was positively associated with observed apnea (hazard ratio [HR] 1.84 [95% CI 1.19-2.86]), snoring (HR 1.27 [95% CI 0.95-1.71]), and daytime sleepiness (HR 1.54 [95% CI 1.13-2.12]). In contrast, we did not find consistent associations between insomnia symptoms and glucose metabolism or incident type 2 diabetes. CONCLUSIONS: Easily collected symptoms of SDB are strongly associated with insulin resistance and the incidence of type 2 diabetes in older adults. Monitoring glucose metabolism in such patients may prove useful in identifying candidates for lifestyle or pharmacological therapy. Further studies are needed to determine whether insomnia symptoms affect the risk of diabetes in younger adults.

ABSTRACT: STUDY OBJECTIVES: Maintaining adequate serum levels of vitamin D may be important for sleep duration and quality; however, these associations are not well understood. We examined whether levels of serum 25(OH)D are associated with objective measures of sleep in older men. SETTING AND PARTICIPANTS: Cross-sectional study within a large cohort of community-dwelling older men, the MrOS study. INTERVENTIONS: Among 3,048 men age 68 years or older, we measured total serum vitamin D. Objective estimates of nightly total sleep time, sleep efficiency, and wake time after sleep onset (WASO) were obtained using wrist actigraphy worn for an average of 5 consecutive 24-h periods. RESULTS: 16.4% of this study population had low levels of vitamin D (< 20.3 ng/mL 25(OH)D). Lower serum vitamin D levels were associated with a higher odds of short (< 5 h) sleep duration, (odds ratio [OR] for the highest (≥ 40.06 ng/mL) versus lowest (< 20.3 ng/mL) quartile of 25(OH)D, 2.15; 95 % confidence interval (CI), 1.21-3.79; Ptrend = 0.004) as well as increased odds of actigraphy-measured sleep efficiency of less than 70% (OR, 1.45; 95% CI, 0.97-2.18; Ptrend = 0.004), after controlling for age, clinic, season, comorbidities, body mass index, and physical and cognitive function. Lower vitamin D levels were also associated with increased WASO in age-adjusted, but not multivariable adjusted models. CONCLUSIONS: Among older men, low levels of total serum 25(OH)D are associated with poorer sleep including short sleep duration and lower sleep efficiency. These findings, if confirmed by others, suggest a potential role for vitamin D in maintaining healthy sleep.

ABSTRACT: OBJECTIVE: This study aims to determine the efficacy of yoga in alleviating vasomotor symptoms (VMS) frequency and bother. METHODS: This study was a three-by-two factorial, randomized controlled trial. Eligible women were randomized to yoga (n = 107), exercise (n = 106), or usual activity (n = 142), and were simultaneously randomized to a double-blind comparison of ω-3 fatty acid (n = 177) or placebo (n = 178) capsules. Yoga intervention consisted of 12 weekly 90-minute yoga classes with daily home practice. Primary outcomes were VMS frequency and bother assessed by daily diaries at baseline, 6 weeks, and 12 weeks. Secondary outcomes included insomnia symptoms (Insomnia Severity Index) at baseline and 12 weeks. RESULTS: Among 249 randomized women, 237 (95%) completed 12-week assessments. The mean baseline VMS frequency was 7.4 per day (95% CI, 6.6 to 8.1) in the yoga group and 8.0 per day (95% CI, 7.3 to 8.7) in the usual activity group. Intent-to-treat analyses included all participants with response data (n = 237). There was no difference between intervention groups in the change in VMS frequency from baseline to 6 and 12 weeks (mean difference [yoga--usual activity] from baseline at 6 wk, -0.3 [95% CI, -1.1 to 0.5]; mean difference [yoga--usual activity] from baseline at 12 wk, -0.3 [95% CI, -1.2 to 0.6]; P = 0.119 across both time points). Results were similar for VMS bother. At week 12, yoga was associated with an improvement in insomnia symptoms (mean difference [yoga - usual activity] in the change in Insomnia Severity Index, 1.3 [95% CI, -2.5 to -0.1]; P = 0.007). CONCLUSIONS: Among healthy women, 12 weeks of yoga class plus home practice, compared with usual activity, do not improve VMS frequency or bother but reduce insomnia symptoms.

8 Article Efficacy and safety of nonbenzodiazepine hypnotics for chronic insomnia in patients with bipolar disorder. 2011

Schaffer, Charles B / Schaffer, Linda C / Miller, Amber R / Hang, Evelyn / Nordahl, Thomas E. ·Department of Psychiatry and Behavioral Sciences, University of California Davis Medical Center, CA, USA. schafferpsych@sbcglobal.net ·J Affect Disord · Pubmed #20701978.

ABSTRACT: BACKGROUND: Insomnia in patients with bipolar disorder (BD) can cause distress, daytime dysfunction, cognitive impairment, worsening of hypomanic/manic symptoms and increased suicide risk. Physicians often prescribe hypnotics for BD patients with insomnia although no hypnotic has a specific FDA indication for this use. In this study, the patterns of use, efficacy and safety of five nonbenzodiazepine hypnotics (NBZHs) were assessed in a large group of outpatients with BD. METHOD: A chart review was performed for all older adolescents and adult BD outpatients in a private outpatient clinic. Clinical data was collected for any patient who had ever been prescribed a NBZH for insomnia and included successful current use, past unsuccessful treatments, side effects, duration of use, concurrent psychiatric medications, and absence or presence of untoward events often associated with chronic use of hypnotics. RESULTS: A significant number of BD patients take NBZHs as needed or on a daily basis. Four NBZHs had adequate success rates; ramelteon was limited in efficacy. Some patients experienced satisfactory results from a NBZH after unsuccessful trials with one or more other NBZHs. About half of the current NBZH users are taking them on a daily long-term basis, and none of these patients have experienced unacceptable untoward events. About three quarters of the chronic NBZH users are taking antimanic medications concurrently, and less than half of the chronic users are taking antidepressants. LIMITATIONS: The results may not be generalizable to other BD populations. A control group was not included in the design. Chronic users of NBZHs were not asked to discontinue their NBZH in order to confirm indication for long-term use. CONCLUSIONS: Most NBZHs can be effective and safe agents for selected BD outpatients with episodic or chronic insomnia. Failure to respond to one or more NBZH does not preclude a satisfactory response to a different NBZH. Some BD patients who take maintenance antimanic agents also require NBZH treatment. Overactivation from antidepressant treatment does not contribute to chronic NBZH use in most BD patients.

9 Article Prevalence of work-related asthma in Michigan, Minnesota, and Oregon. 2010

Lutzker, Liza A / Rafferty, Ann P / Brunner, Wendy M / Walters, Jaime K / Wasilevich, Elizabeth A / Green, Mandy K / Rosenman, Kenneth D. ·Massachusetts Department of Public Health, Occupational Health Surveillance Program, Boston, Massachusetts, USA. liza.lutzker@cdph.ca.gov ·J Asthma · Pubmed #20170322.

ABSTRACT: INTRODUCTION: Adults who have asthma that is caused or aggravated by triggers at work experience a reduced quality of life. In this study, the authors sought to estimate the proportion of asthma that is associated with work using a state-based survey of adults with asthma. METHODS: In 2005, Michigan, Minnesota, and Oregon piloted the Behavioral Risk Factor Surveillance System Adult Asthma Call-Back Survey, with sample sizes of 867, 469, and 1072, respectively. Six questions addressing work-related asthma (WRA) were analyzed to generate estimates of the proportion of adult asthma that is work-related and compare those with and without WRA. RESULTS: Over half of all adults with asthma (53%) reported that their asthma was caused or made worse by any job they ever had, and among these respondents reporting WRA, only 21.5% to 25.1% reported ever telling or being told by a health professional that their asthma was work-related. Additionally, adults with WRA consistently reported poorer asthma control and higher health care utilization than adults with non-WRA. CONCLUSIONS: WRA is a common but frequently unrecognized health problem, and this lack of recognition might contribute to poorer asthma control among adults with WRA. Because early recognition, treatment, and management of WRA are crucial for improving long-term prognosis, clinicians need to include assessment of workplace triggers in both their diagnostic and treatment plans for adult patients with asthma.
