What are the main findings? Response: Short sleep duration and sleep fragmentation are associated with adverse health outcomes including cardiovascular disease, diabetes, hypertension, certain cancers, and mental health challenges such as depression and anxiety. Avoiding the use of alcohol, caffeine, and nicotine close to bedtime represent modifiable behaviors that can improve sleep. Nonetheless, among community dwelling adults (e.g., adults in their natural bedroom environment as opposed to research laboratories) and specifically African Americans, there is a lack of longitudinal research investigating the use of these substances and the associations with objective measures of sleep..

What are the main findings? Response: I'm a sleep researcher and I wanted to find the link between warm bath and sleep. Body temperature which is involved in the regulation of the sleep/wake cycle, exhibits an endogenous circadian cycle, that is a 24-hour pattern, being highest by 2-3°F in the late afternoon/early evening than during sleep when it's lowest. The average person’s circadian cycle is characterized by a reduction in core body temperature by ~ 0.5 to 1° F the hour or so before one’s usual sleep time, dropping to its lowest level between the middle and later span of nighttime sleep. It then begins to rise, acting as a kind of a biological alarm clock wake-up signal. The temperature cycle leads the sleep cycle and is an essential factor in achieving rapid sleep onset and high efficiency sleep.

Response: Chronic disorders of sleep and wakefulness affect an estimated 50-70 million adults in the United States. The cumulative long-term effects of sleep loss have been associated with a wide range of damaging health consequences, including obesity, diabetes, impaired glucose tolerance, cardiovascular disease, hypertension, anxiety and depression. In terms of preventing health consequences, sleeping 6-8 hours per night consistently may provide optimal health outcomes. Comprehensive data from two recently completed patient-reported outcomes (PRO) studies provide further evidence of the observed hypnotic effects of REMfresh, demonstrating statistically significant improvements in sleep onset, sleep duration, sleep maintenance and sleep quality. PRO studies of this kind, which more closely address real-world patient experience, are increasingly being recognized by regulatory authorities and academia in evaluating new therapies. In addition to the traditional randomized, placebo-controlled trial studies, regulatory authorities are now incorporating the patient perspective in their decision making, including PRO studies. A PRO study is a measurement based on a report that comes directly from the patient about the status or change in their health condition and without amendment or interpretation of the patient's response by health-care intermediaries. PRO measures can be used to capture a patient's everyday experience outside of the clinician's office, and the effects of a treatment on the patient's activities of daily living. Together, clinical measures and PRO measures can provide a fuller picture of patient benefit. REMfresh, the first and only continuous release and absorption melatonin (CRA-melatonin) formulation, is designed to give patients up to 7 hours of sleep support. It is a clinically studied, drug-free, nonprescription, #1 sleep doctor-recommended melatonin sleep brand.
Alzheimer's - Dementia, Author Interviews, Sleep Disorders / 21.06.2019

sleep-alzheimers-dementia-insomniaSleep patterns can predict the increase of Alzheimer’s pathology proteins tau and β-amyloid later in life, according to a June 2019 study published in the Journal of Neuroscience. The findings shed hope on earlier diagnosis of Alzheimer’s and the adoption of preventive measures earlier in life. Researchers found a decrease in sleep spindle synchronization, which is linked to higher tau levels. Reduced amplitude of slow wave activity, meanwhile, is closely related to higher β-amyloid levels. In younger people, both slow oscillations and sleep spindles are synchronized. This changes as people grow older, with less coordination between the two being visible. The researchers also noted that subjects who slept less had a higher chance of having Alzheimer’s proteins when they were older. The findings show that both reduced sleep quantity and quality can serve as important warnings of the onset of Alzheimer’s.

Response: Restless legs syndrome (RLS) is a common neurological disorder, affecting up to 10% of the general population in Europe and North America. It is a sensorimotor disorder characterized by unpleasant sensations and an urge to move, mainly involving the legs. These symptoms appear or worsen in the evening/at night and improve with movement. Background for this study was the idea that there might be gender differences in the phenotypical presentation of RLS, as the pathogenesis of this disease is multifactorial and gender specific factors also play a role.

MedicalResearch.com Interview with: [caption id="attachment_49610" align="alignleft" width="133"]Dr-Nicole Tang Dr. Tang[/caption] Nicole Tang, D.Phil, C.Psychol (Reader) Department of Psychology Warwick Sleep and Pain Lab University of Warwick MedicalResearch.com: What is the background for this study? What are the main findings? Response: Current guidelines recommend non-opioid therapy as the preferred treatment of chronic non-malignant (CNP) pain, with opioids reserved to situations “when benefits for pain and function are expected to outweigh risks” [1,10]. Whilst the effectiveness of opioid therapy is usually measured in terms of pain outcomes, less is known about its effect on day-to-day functions. A particular function of concern to patients with chronic non-malignant pain is the ability to get a good night's sleep. The current systematic review has identified a set of papers with relevant outcomes regarding the effect of opioid therapy on sleep quality and sleep architecture in CNP patients. It extends our understanding from the drug's respiratory depression effect in healthy individuals to the potential risks and utility of opioid therapy for chronic non-malignant pain patients with sleep disturbances. Whilst the narrative synthesis and the exploratory meta-analysis of a subset of data both suggest that the use of opioid therapy is associated with an overall report of sleep quality improvement, such an improvement is not consistently replicated across studies or substantiated by improvements in sleep parameters linked to deeper and better-sleep quality. Moreover, the improvement may be accompanied by undesirable side effects and increased daytime sleepiness that contradict with the very idea of improved sleep quality. We are also painfully aware of the methodological limitations of the studies reviewed; their exposure to different sources of biases has heightened the risk of result inflation. To many patients with chronic non-malignant pain, improved sleep is a top priority when evaluating the performance of a new drug and non-drug intervention. If we were to advance our current understanding of the opioid-sleep relationship, future trials need to be designed with this interdisciplinary question in mind such that validated measures of sleep can be incorporated as an outcome measure alongside pain.

What are the main findings?  Response: Unintentional suffocation is the leading cause of injury death among infants under 1 year old in the US. This study investigates cases in CDC’s SUID Case Registry that were assigned the category of explained suffocation with unsafe sleep factors per CDC’s SUID Case Registry classification system, which was developed to consistently differentiate SUID cases into well-defined categories (including no autopsy or death scene investigation, incomplete case information, no unsafe sleep factors, unsafe sleep factors, possible suffocation with unsafe sleep factors, and explained suffocation with unsafe sleep factors) using standardized criteria and definitions. Cases classified as possible and explained suffocation were assigned one more mechanisms to which the airway obstruction was attributed including soft bedding, wedging, overlay and other – other was excluded from this analysis. Most explained suffocations (69%) were attributed to soft bedding like a blanket or a pillow followed by overlay (19%), and wedging (12%). Although explained suffocation deaths represent a small proportion of all sudden unexpected infant deaths (14%), these losses are particularly tragic because they can be prevented by placing a baby to sleep in a safe environment.

Cohen, M.D., Ph.D., Senior Investigator Marlene Bönstrup, M.D., Postdoctoral fellow in  Dr. Cohen's lab NIH's National Institute of Neurological Disorders and Stroke MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Learning a new skill is typically divided into online (during practice) and offline (after practice has ended) components. Particularly motor skill learning occurs to a considerable degree offline, meaning that performance further improves even after practice has ended. A single practice session itself however, is typically divided into short (level of seconds) periods of practice and rest. In this study, we set out to investigate the contribution of those short periods of practice and rest to the learning during a practice session (i.e. online learning). We found that during early motor skill learning, when most of the total learning occurs, performance improvements actually precipitate during short periods of rest whereas during practice periods, performance mostly stagnated. We found a signature of neural activity predictive of those performance improvements during rest: The lower the beta rhythmic activity in the parietofrontal regions of the brain during those short periods of rest, the higher were participant’s performance jumps.

Response: The wellbeing and development of children is strongly influenced by parents’ physical and psychosocial health. Parents of children with chronic illness, in particular, are susceptible to poor sleep, and previous studies have found major sleep impairments among parents of children with ventilator dependency and cystic fibrosis, but few studies have examined sleep patterns among parents of children with more common chronic illnesses like atopic dermatitis (also known as eczema).

What are the main findings?  Response: Lifestyle changes represent the cornerstone of treatment of arterial hypertension. Alcohol and salt reduction may decrease blood pressure levels by 2 to 8 mmHg. In our study 60 minutes of midday sleep decrease 24 hours systolic blood pressure levels by up to 3 mmHg in well controlled hypertensives. That is an effect as potent as other well-established life style changes. The magnitude of blood pressure decrease might seem small, but a drop in blood pressure as small as 2 mmHg can reduce the risk of cardiovascular events by up to 10 percent.

What are the main findings?  Response: Sufficient sleep of good quality is important for physical and mental health. Therefore, we are studying factors in people’s lives that may affect their sleep. In the present study we examined in particular how the birth of a child affects parents’ sleep. In detail, we used data on sleep of more than 4,600 parents in Germany who had a child between 2008 and 2015. During these years parents reported on their sleep in yearly interviews. We found that the birth of a child had quite drastic short-term effects on new mothers’ sleep, particularly during the first three months after birth. This is not a new finding; previous studies reported similar effects. What is new in the current study is that we compared sleep before pregnancy with sleep until up to 6 years after birth. We were surprised to see that sleep duration and sleep satisfaction were still decreased up to six years after birth. Six years after birth mothers and father still slept around 15-20 minutes less.

McAlpine, Ph.D. Banting Postdoctoral Fellow Center for Systems Biology Massachusetts General Hospital Harvard Medical School Boston, MA, 02114 MedicalResearch.com: What is the background for this study? What are the main findings? Response: Cardiovascular disease is caused by the build up of white blood cells and fat in arteries. We have known for a long time that poor sleep is associated with an increased risk of developing cardiovascular disease. A number of human observational studies have found this correlation. However, the reasons for this correlation have been largely unknown. Our study, performed in mice, provides one possible explanation. We found that when we disturbed the sleep of mice they produced more inflammatory white blood cells. These cells caused larger lesions in their arteries and more advanced cardiovascular disease. We found that his phenomenon is controlled by a hormone produced in the brain that normally suppresses the production of white blood cells. When mice have their sleep disturbed this pathway breakdown causing the increased production of white blood cells.

What are the main findings? Response: Slow wave sleep (deep sleep) is known to be very important for memory reorganization. The brain goes through the memory traces that were created during wakefulness and strengthens the important ones, while unimportant ones are weakened or deleted to make room for new learning the next day. This happens during the peaks of the eponymous slow waves, also called up-states, where the brain is highly active and interconnected. Up-states last for about 0.5 sec before transitioning into down-states, where the brain is relatively silent. Based on these findings, we hypothesized that up-states constitute windows of opportunity to learn new information during slow wave sleep: The "channels are open", and the brain is already performing memory functions. The results of our study support this hypothesis. We found that, if we repeatedly managed to synchronize presentation of word pairs with up-states, memory for these pairs was best. Moreover, we find a dose-response function: The more often word pairs hit up-states, the better the memory. On top of that, fMRI during the retrieval test suggests that the same brain regions are involved in sleep learning as are involved in learning during wakefulness.

Yet, we also have plenty of anecdotal reports of adults falling asleep faster when in a train or a car, as well as a feeling of relaxation in a hammock. Our companion paper on mice (Kompotis et a., 2019 – same issue in Current Biology) clearly established that the beneficial effects of rocking on sleep relied on the activation of the vestibular system and might thus suggest some shared neurophysiological mechanisms in mammals.

Ordovás, PhD Director Nutrition and Genomics Professor Nutrition and Genetics JM-USDA-HNRCA at Tufts University Boston, MA 02111 MedicalResearch.com: What is the background for this study? Response: The current knowledge supports the notion that poor sleep is associated with cardiovascular risk factors such as obesity, hypertension, and diabetes. Besides, there is some proof that poor sleep might be related to the development of atherosclerosis; however, this evidence has been provided by studies including few participants and, in general, with sleep disorders, such as sleep apnea. Our research has used state-of-the-art imaging technology to measure plaque buildup in the arteries, and objective measures of sleep quantity and quality in about 4000 participants of the PESA CNIC- Santander Study. Moreover, this is the first study to look at the multiterritory development of plaques versus other studies that looked exclusively at the coronary arteries. Therefore, this combination provides stronger evidence than previous studies about the risk of poor sleep on the development of atherosclerosis.

Response: Alzheimer’s disease and sleep are currently thought to have a two-way or bidirectional relationship. First, sleep disturbances may increase the risk of developing AD. Second, changes in sleep-wake activity may be due to Alzheimer’s disease pathology and our paper was primarily focused on this aspect of the relationship.    If sleep changes were a marker for AD changes in the brain, then this would be very helpful in future clinical trials and possibly screening in the clinic.

What are the main findings? Response: Our lab is interested in the dynamics of sleep and sleep-like rhythms in the forebrain. One particular interest relates to how the brain can spontaneously switch between very different states like rapid eye movement sleep (REM, or dreaming sleep) and slow-wave sleep (deep, restorative stage of sleep). We noticed that administering 100% oxygen to rats in an anesthetized preparation that closely models natural sleep produced an immediate and lasting switch into a slow-wave brain state. This happened as well in naturally sleeping rats. Interestingly, increasing carbon dioxide concentrations or decreasing oxygen in inspired air produced the opposite effect, namely a switch into activated or REM-like states.

For example, a growing literature shows that simply educating students on the importance of sleep does not change their sleep behaviors. Thus, we need to think outside of the box for solutions. In three classes, we have now investigated a motivational solution: if students can earn extra credit on their final exam for sleeping better, will they do so even during finals week?

What are the main findings? Response: Women who are going through menopause frequently complain of sleep complaints and depressive symptoms in addition to other typical symptoms such as hot flashes and night sweats. Two of the most common ways of becoming menopausal are through natural menopause and surgical menopause. While natural menopause is usually experienced in the course of aging, surgical menopause is usually induced by OBGYN surgery such as bilateral oopherectomy, often as a result of illnesses such as ovarian cancer. Many studies have found that women who experience surgical menopause often experience more psychological and physical difficulties compared to women who transition through menopause naturally due to a more acute drop in estrogen following surgery, it sometimes leads to the need for practices like Advanced Gynecology to help manage the symptoms. Unfortunately, in clinical settings, women who undergo surgical menopause are not provided with additional psychoeducation or customized treatment to address these issues. The main findings of these studies support these issues. In 526 postmenopausal women, women who went through surgical menopause reported significantly worse sleep quality an shorter sleep duration. Additionally, they had a 2.13 times higher likelihood of having insomnia that warranted treatment. Finally, even though women who went through surgical menopause engaged in the same sleep-interfering behaviors (e.g., drinking caffeine, drinking alcohol before bed, watching TV in bed, etc) as women who went through menopause naturally, their sleep was impacted more negatively.

Wikipedia image[/caption] Tom Marshall, MSc, PhD, MRCGP, FFPH Professor of public health and primary care Institute of Applied Health Research University of Birmingham, Birmingham, UK MedicalResearch.com: What is the background for this study?   Response: Tonsillectomy is one of the most common childhood surgical procedures. There are two main indications: recurrent sore throat and sleep-related breathing problems (including obstructive sleep apnoea). Jack Paradise’s 1984 study made clear tonsillectomy is modestly effective in children with frequent, severe sore throats: seven in one year, or five yearly in two successive years, or three yearly in three successive years. Sore throats must have symptoms: fever, pus seen on tonsils, lymphadenopathy or confirmed Streptococcal infection. With surgery, children average two sore throats in the next year, without surgery, three. Two years later there is no difference. Further research shows the benefits are too tiny to justify surgery in children with less frequent, less severe or undocumented sore throats. Subsequent randomised controlled trials have not changed the evidence. There isn’t enough good evidence to support surgery in children with obstructive sleep apnoea or sleep related breathing problems. Tonsillectomy is not a trivial procedure, about 2% are readmitted with haemorrhage and about 1 in 40,000 dies. Childhood tonsillectomy is linked to risk of adult autoimmune diseases. It is important to be sure tonsillectomy is only undertaken in children where there are evidence-based indications.

MedicalResearch.com Interview with: "Snoring away" by Doug Ford is licensed under CC BY 2.0Matthew P Butler, PhD Assistant Professor, Oregon Institute of Occupational Health Sciences Assistant Professor, Department of Behavioral Neuroscience Oregon Health & Science University Portland, OR 97239 MedicalResearch.com: What is the background for this study? What are the main findings? Response: Obstructive sleep apnea (OSA) is associated with heart disease and mortality, but how OSA does this is not well understood. We are therefore looking for sub-phenotypes within OSA that will help us predict who is at greatest risk. Current diagnosis of OSA is made on the basis of the apnea-hypopnea index (AHI – the number of respiratory events per hour of sleep). But the AHI is not a very good predictor of future mortality. We tested the hypothesis that the duration of events (how long the breathing interruptions are) would predict risk. We found that those with the shortest breathing interruptions had the highest risk of dying, after accounting for other conditions like age, gender, race, and smoking status.

Can you briefly describe what is meant by RLS  and who suffers from it? Response: Restless Legs Syndrome (RLS) is a common neurological disorder characterized by an irritating, overwhelming urge to move (akathisia) the legs while at rest or sleep (conditions of diminished arousal), which almost immediately abates with mental or physical activity (conditions of maintained arousal). One of the most clinically-profound and scientifically relevant consequences of this disease process is an increased arousal state producing significant wake during sleep times and a relative sustainable degree of daytime alertness despite the degree of diseased-imposed sleep loss. The focus of most previous RLS research has been on the (limb) akathisia with associated periodic movements and reduction of these with dopaminergic treatment. Little research has been done to understand the broader biological dimensions​ of RLS. Patients with RLS have altered sleep-wake homeostasis with increased arousal and wakefulness (hyperarousal) not only driving the signature clinical symptoms (“the urge to move” and sleep loss) but also supporting arousal over sleep drive at night and in the day. We hypothesize that there is a basic glutamate-hyperarousal process producing both disrupted sleep (increased wake time) and cortical excitability (as demonstrated by transcranial magnetic stimulation (TMS)).​

What are the main findings? Response: We know that in young adults, sleep contributes to emotion processing. We wondered if naps work similarly for preschool children.  To look at this, we had children learn an emotional memory task and then either take a nap or stay awake.  We then tested their memory after that interval and again the next day. We found that when children napped, they had better memory for those items the next day than if they did not nap.  That the naps seem to support memory (even if in a delayed fashion) seems consistent with the observation of parents and preschool teachers that children are often emotionally dysregulated if they do not nap.

Duncan, ScD Associate Professor Director, NYU Spatial Epidemiology Lab Department of Population Health NYU School of Medicine NYU Langone Health MedicalResearch.com: What is the background for this study? Response: Sleep and sleep hygiene have emerged as one of the major determinants of health and wellbeing (alongside good diet, regular exercise, and not smoking). However, a small number of studies have used population-representative samples to examine sexual orientation disparities in sleep. Our study aimed to fill this gap in knowledge.
Alzheimer's - Dementia, Author Interviews, Obstructive Sleep Apnea, Sleep Disorders / 07.07.2018

MedicalResearch.com Interview with: “Woman sleeping” by Timothy Krause is licensed under CC BY 2.0Nathan E. Cross PhD, first author School of Psychology. Sharon L. Naismith, PhD, senior author Leonard P Ullman Chair in Psychology Brain and Mind Centre Neurosleep, NHMRC Centre of Research Excellence The University of Sydney, Australia  MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Between 30 to 50% of the risk for dementia is due to modifiable risk factors such depression, hypertension, physical inactivity, obesity, diabetes and smoking. In recent years, multiple longitudinal cohort studies have observed a link between sleep apnoea and a greater risk (1.85 to 2.6 times more likely) of developing cognitive decline and dementia.  Furthermore, one study in over 8000 people also indicated that the presence of obstructive sleep apnoea (OSA) in older adults was associated with an earlier age of cognitive decline, and that treatment of OSA may delay the onset of cognitive impairment. This study reveals important insights into how sleep disorders such as OSA may impact the brain in older adults, as it is associated with widespread structural alterations in diverse brain regions. We found that reduced blood oxygen levels during sleep are related to reduced thickness of the brain's cortex in both the left and right temporal areas - regions that are important in memory and are early sites of injury in Alzheimer's disease. Indeed, reduced thickness in these regions was associated with poorer ability to learn new information, thereby being the first to link this structural change to memory decline.
Accidents & Violence, Author Interviews, Sleep Disorders / 07.07.2018

MedicalResearch.com Interview with: “Driving...” by Stig Nygaard is licensed under CC BY 2.0Prof. Stephen R Robinson PhD Discipline Leader, Psychology School of Health and Biomedical Sciences RMIT University Australia MedicalResearch.com: What is the background for this study? Response: Around the world, driver drowsiness and fatigue are estimated to contribute to 250,000 deaths on the road per year. Current research in this area has focused on detecting when drivers become drowsy, by examining their eye movements or steering patterns, and then alerting the driver with a warning tone or vibration of the steering wheel. Rather than this reactive approach, we are interested in helping to prevent drivers from becoming drowsy in the first place.
Author Interviews, Melatonin, Sleep Disorders / 15.06.2018

MedicalResearch.com Interview with: David C. Brodner, M.D. Founder and Principle Physician, The Center for Sinus, Allergy, and Sleep Wellness Double Board-Certified in Otolaryngology (Head and Neck Surgery) and Sleep Medicine Assistant Clinical Professor, Florida Atlantic University College of Medicine Medical Director, Good Samaritan Hospital Sleep Laboratory Senior Medical Advisor, Physician’s Seal, LLC® MedicalResearch.com: What is the background for this study? Response: Melatonin is produced by the pineal gland in the brain and is the body’s natural sleep ingredient. Melatonin levels normally begin to rise in the mid-to late evening and remain high for the majority of the night. Levels begin to decline towards early morning, as the body’s wake cycle is triggered. Research shows that as people age, melatonin levels can drop by as much as 70 percent and their bodies may no longer produce enough melatonin to ensure adequate sleep. Other available products, such as immediate-release melatonin, help initiate the onset of sleep but are usually unable to sustain prolonged sleep maintenance due to an immediate burst of melatonin, which is quickly degraded due to its relatively short half-life (60 minutes). Absorption in the lower digestive tract is limited by melatonin’s limited ability to be absorbed in a low acidity or neutral pH environment. This post-marketing REMfresh® Patient Reported Outcomes DURation (REMDUR) study was designed to obtain real-world evidence about patients’ sleep patterns, duration of sleep before and after REMfresh® (CRA-melatonin™), daily REMfresh® (CRA-melatonin™) use, onset of action, sleep maintenance, quality of sleep, and overall satisfaction with REMfresh® (CRA-melatonin™). Patients with sleep disturbances in the general population who received a sample of CRA-melatonin™ (REMfresh®) from their physicians were invited to complete a 12-question survey. Survey responses were received from 500 patients.
