Abstract
Sleep deficiency is a common problem in the hospital setting. Contributing factors include preexisting medical conditions, illness severity, the hospital environment, and treatment-related effects. Hospitalized patients are particularly vulnerable to the negative health effects of sleep deficiency that impact multiple organ systems. Objective sleep measurement is difficult to achieve in the hospital setting, posing a barrier to linking improvements in hospital outcomes with sleep promotion protocols. Key next steps in hospital sleep promotion include improvement in sleep measurement techniques and harmonization of study protocols and outcomes to strengthen existing evidence and facilitate data interpretation across studies.

Abstract
Light therapy and the effects on biological function have been known and investigated for decades. Light therapy is used to compensate for the lack of exposure to sunlight, which is thought to be linked to major depressive disorder with seasonal patterns. It is applied as sessions with bright light mimicking natural sunlight. Lack of bright light during daytime is not the only factor to maintain the circadian rhythm, also lack of exposure to bright light at night is important. A new modality called naturalistic light shows promise, mimicking daylight by dynamically changing intensity and wavelengths throughout the day. Evidence of clinical effects, besides bright light effects on depression, is still limited, especially in hospital populations, and present review aims to extract results of the effect of any optical light intervention on hospitalized patients. Through database search, 29 trials were included, of which 8 trials used a variation of naturalistic light. Trials were heterogeneous regarding designs, populations, interventions, methods and outcomes. In 14 out of 17 studies investigating sleep duration, quality and circadian alignment, along with decreased fatigue and improved mood in daytime, light therapy had a significant effect. Circadian rhythm and rhythmicity were affected as well. The effect on mood and cognition was inconsistent across studies. Trials showed more significant outcomes when conducted in non-intensive care units and with duration >5 days. Lux was reported in and compared across 24 studies and did not appear to be correlated to outcome, rather the distribution of wavelengths should be considered when conducting trials in the future. Of the 8 trials investigating naturalistic light, 4 trials had significant outcomes and 3 had adverse outcomes compared to one in the standard light regime. The overall effect of light therapy is beneficial, but evidence for the effect of naturalistic light is still insufficient to be recommended before other modalities. Future research in this area should be conducted in facilities where naturalistic light is installed, with a focus on the spectral distribution.

Abstract
BACKGROUND Cancer-related sleep disturbance is common and can adversely affect physical and mental health. Bright light (BL) therapy is a novel intervention that targets sleep by promoting circadian regulation. Emerging evidence suggests BL can improve sleep disturbance, symptom burden, and health-related quality of life in cancer and other populations; however, this research is limited. The present two-phase pilot study assessed the feasibility and preliminary intended effects of BL therapy on sleep in ovarian and endometrial cancer survivors, and explored biologic and chronobiologic factors that may underlie intervention effects. METHODS In phase I, focus groups were conducted with 12 survivors and 9 gynecologic oncology clinicians to evaluate and gather feedback about the proposed study. In phase II, a pilot randomized controlled trial was conducted with 18 ovarian or endometrial cancer survivors who were randomized 1:1 to receive 45 min of BL or dim light (DL) for 4 weeks. Participants wore wrist actigraphs; completed sleep diaries and self-report questionnaires; and provided blood, saliva, and urine samples at baseline (T1), post-intervention (T2), and 3-month follow-up (T3). RESULTS Study procedures were modified according to focus group results. Enrollment, retention, and adherence were all ≥ 80%. Mixed-model ANOVAs demonstrated that the number of nighttime awakenings per actigraphy, and sleep quality and depression per self-report, trended toward improvements in the BL condition compared to the DL condition. These variables improved from T1 to T2 before returning to baseline at T3. Effect sizes were generally medium to large. CONCLUSIONS Study findings suggest that BL therapy is feasible among ovarian and endometrial cancer survivors. It may be an effective, non-pharmacological approach to reduce sleep disturbance and symptom burden in this population.

Abstract
Worldwide, individuals are living longer due to medical and scientific advances, increased availability of medical care and changes in public health policies. Consequently, increasing attention has been focused on managing chronic conditions and age-related diseases to ensure healthy aging. The endogenous circadian system regulates molecular, physiological and behavioral rhythms orchestrating functional coordination and processes across tissues and organs. Circadian disruption or desynchronization of circadian oscillators increases disease risk and appears to accelerate aging. Reciprocally, aging weakens circadian function aggravating age-related diseases and pathologies. In this review, we summarize the molecular composition and structural organization of the circadian system in mammals and humans, and evaluate the technological and societal factors contributing to the increasing incidence of circadian disorders. Furthermore, we discuss the adverse effects of circadian dysfunction on aging and longevity and the bidirectional interactions through which aging affects circadian function using examples from mammalian research models and humans. Additionally, we review promising methods for managing healthy aging through behavioral and pharmacological reinforcement of the circadian system. Understanding age-related changes in the circadian clock and minimizing circadian dysfunction may be crucial components to promote healthy aging.

Abstract
OBJECTIVE Poor sleep is highly prevalent in inpatient medical settings and has been associated with attenuated healing and worsened outcomes following hospitalization. Although nonpharmacological interventions are preferred, little is known about the best way to intervene in hospital settings. METHOD A systematic review of published literature examining nonpharmacological sleep interventions among inpatients in Embase, PsycINFO and PubMed in accordance with PRISMA guidelines. RESULTS Forty-three of the 1529 originally identified manuscripts met inclusion criteria, encompassing 2713 hospitalized participants from 18 countries comprised of psychiatric and older adult patients living in hospital settings. Main outcomes were subjective and objective measures of sleep duration, quality, and insomnia. CONCLUSIONS Overall, the review was unable to recommend any specific intervention due to the current state of the literature. The majority of included research was limited in quality due to lack of controls, lack of blinding, and reliance on self-reported outcomes. However, the literature suggests melatonin and CBT-I likely have the most promise to improve sleep in inpatient medical settings. Additionally, environmental modifications, including designated quiet time and ear plugs/eye masks, could be easily adopted in the care environment and may support sleep improvement. More rigorous research in nonpharmacological sleep interventions for hospitalized individuals is required to inform clinical recommendations.

Abstract
AIM Numerous studies have explored the effectiveness of bright light therapy as a treatment of sleep disorders in nursing home and long-stay geriatric hospital residents, most of whom have dementia. A recent Cochrane Collaboration meta-analysis of 10 selected studies concluded that there was insufficient evidence to assess its therapeutic efficacy as most available studies had methodological problems. We sought to remedy this situation by developing proposals to guide research methods in future studies. METHODS Based on the literature and our own clinical and research experience, we developed a series of proposals relating to study design, participant selection, light delivery modalities and outcome measures that we believe will maximize the chances of identifying a bright light treatment effect. We then checked adherence to these proposals in all relevant published experimental studies. RESULTS Of the 18 studies published in the last two decades that met our selection criteria, only half the studies had selected participants with a sleep disorder. Eleven studies excluded people with severe vision loss; seven included a clinical rating of sleep, and five measured baseline lighting levels. Most checked psychoactive medication prescriptions but few reported changes in prescriptions over the course of the study. Most also checked treatment adherence and included some control for differences in amount of social contact. CONCLUSIONS Evidence for the effectiveness of bright white light treatment in people residing in nursing homes is equivocal. We anticipate that the quality of this evidence will be improved if researchers refine their study methods and adopt a more uniform approach.

Abstract
Disordered sleep in persons with dementia is a contributing factor for a range of health problems. The evidence base for non-pharmacological interventions has not been evaluated and clearly presented in the literature. This paper provides a structured Critical Literature Review of the evidence for non-pharmacological interventions to reduce disordered sleep in persons with dementia. The systematic search retrieved 29 studies that were evaluated for methodological quality. The quality of evidence ranged from conclusive for light therapy and activity to inconclusive for most other interventions. There is a paucity of conclusive research for non-pharmacological sleep interventions for persons with dementia. Most of the evidence about effective interventions is anecdotal and untested. There is a need for rigorous scientific inquiry, coupled with tacit knowledge to build a strong evidence base on non-pharmacological interventions for disordered sleep for persons with dementia.

Abstract
The treatment of sleep-related illness in older patients must be undertaken with an appreciation of the physiologic changes associated with aging. Insomnia is common among older people. When it occurs secondary to another medical condition, treatment of the underlying disorder is imperative. Benzodiazepines, although potentially effective, must be used with care and in conservative doses. Daytime sedation, a common side effect, may limit use of benzodiazepines. Newer non-benzodiazepine drugs appear to be promising. Rapid eye movement (REM) sleep behaviour disorder can be treated with clonazepam, levodopa-carbidopa or newer dopaminergic agents such as pramipexole. Sleep hygiene is important to patients with narcolepsy. Excessive daytime sleepiness can be treated with central stimulants; cataplexy may be improved with an antidepressant. Restless legs syndrome and periodic leg-movement disorder are treated with benzodiazepines or dopaminergic agents such as levodopa-carbidopa and, more recently, newer dopamine agonists. Treatment of obstructive sleep apnea includes weight reduction and proper sleep positioning (on one's side), but may frequently necessitate the use of a continuous positive air-pressure (CPAP) device. When used regularly, CPAP machines are very effective in reducing daytime fatigue and the sequelae of untreated obstructive sleep apnea.

Abstract
Sleep disorders are common in PD and many factors can contribute to disturbed nocturnal sleep and daytime sleepiness. Factors contributing to sleep disturbance include the presence of insomnia, mood or anxiety disorders, dementia, specific sleep disorders, PD motor disorders, and the effects of PD or medications. Patients who have PD should be interrogated about sleep disturbance and daytime sleepiness and preferably, because of underestimation of the severity of sleepiness or lack of awareness, patients should be interviewed in the presence of a close friend or relative. The ability to drive, if sleepiness is present, should be assessed and appropriate recommendations made. Treatment of sleepiness involves treating any underlying sleep disturbance and may involve the use of stimulant or alerting medications in the daytime.

Abstract
BACKGROUND The prevalence of sleep problems in adulthood increases with age. While not all sleep changes are pathological in later life, severe disturbances may lead to depression, cognitive impairments, deterioration of quality of life, significant stresses for carers and increased healthcare costs. The most common treatment for sleep disorders (particularly insomnia) is pharmacological. The efficacy of non-drug interventions has been suggested to be slower than pharmacological methods, but with no risk of drug-related tolerance or dependency. Bright light treatment involves participants sitting in front of a "light box" which emits very high (typically 10,000 lux) fluorescent light for periods of around two hours daily. The timing of this light treatment will depend on the irregular timing of the participant's sleep pattern. OBJECTIVES To assess the efficacy of bright light therapy in improving sleep quality (sleep timing in particular) amongst adults aged 60 and above. SEARCH STRATEGY The following databases were searched: MEDLINE (1966 - January 2001); EMBASE (1980 - January 2001), CINAHL ( 1982 - January 2001; PsychINFO 1970 to 2001; The Cochrane Library (Issue 1, 2001); National Research Register (NRR [2001]). Bibliographies of existing reviews in the area, as well as of all trial reports obtained, were searched. Experts in the field were consulted. SELECTION CRITERIA Randomised controlled trials of bright light therapy for primary sleep problems where 80% or more of participants were over 60. Participants must have been screened to exclude those with dementia and/or depression. DATA COLLECTION AND ANALYSIS Abstracts of studies identified in searches of electronic databases were read and assessed to determine whether they might meet the inclusion criteria. MAIN RESULTS Reviewers found no trials on which to base conclusions for the effectiveness of this treatment. REVIEWER'S CONCLUSIONS When the possible side-effects of standard treatment (hypnotics) are considered, there is a reasonable argument to be made for clinical use of non-pharmacological treatments. In view of the promising results of bright light therapy in other populations with problems of sleep timing, further research into their effectiveness with older adults would seem justifiable.
