MedicalResearch.com Interview with: [caption id="attachment_46941" align="alignleft" width="133"]José M. Ordovás, PhD Director Nutrition and Genomics Professor Nutrition and Genetics            JM-USDA-HNRCA at Tufts University Boston, MA 02111 Dr. Ordovás[/caption] José M. 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.

MedicalResearch.com Interview with: [caption id="attachment_46932" align="alignleft" width="137"]Brendan P. Lucey, MD, MSCI Assistant Professor of Neurology Director, Sleep Medicine Section Washington University School of Medicine Saint Louis, Missouri 63110 Dr. Lucey[/caption] Brendan P. Lucey, MD, MSCI Assistant Professor of Neurology Director, Sleep Medicine Section Washington University School of Medicine Saint Louis, Missouri 63110 MedicalResearch.com: What is the background for this study? 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.

Scullin, Ph.D. Assistant Professor of Psychology and Neuroscience Director, Sleep Neuroscience and Cognition Laboratory Baylor University Waco, TX 76798  MedicalResearch.com: What is the background for this study? What are the main findings?  Response: There is a gap between what health behaviors individuals know they should adopt, and what those individuals actually end up doing. 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?

MedicalResearch.com Interview with: [caption id="attachment_45992" align="alignleft" width="142"]Sooyeon Suh, PhD Department of Psychology Sungshin University Seoul, Republic of Korea Dr. Suh[/caption] Sooyeon Suh, PhD Department of Psychology Sungshin University Seoul, Republic of Korea MedicalResearch.com: What is the background for this study? 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.
Author Interviews, Obstructive Sleep Apnea / 22.10.2018

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.

Weaver, PhD Instructor in Medicine · Harvard Medical School Associate Epidemiologist · Division of Sleep and Circadian Disorders Brigham and Women's Hospital Boston, MA 02215 MedicalResearch.com: What is the background for this study? Response: We were interested whether high school students who tended to sleep less than 8 hours per night reported more risk-taking behaviors compared to high school students who slept at least 8 hours per night on a school night. We utilized a nationally representative dataset from the CDC of surveys that were completed by high school students between 2007 and 2015. Over that time, approximately 67,000 students were surveyed. Students were asked about the hours of sleep that they obtained on an average school night. They were also asked how often, in the month prior to the survey, they engaged in a number of risk-taking behaviors. Some behaviors were related to driving, like driving without a seatbelt or driving drunk, while others were related to using alcohol, doing drugs, or being involved in a fight. They were also asked about their mood, including whether they felt sad or hopeless, considered suicide, and whether they had attempted suicide.

Salas, MD, MEHP, FAAN Associate Professor, Neurology and Nursing at Johns Hopkins Medicine Director, Interprofessional Education and Interprofessional Collaborative Practice Director, Neurology Clerkship Director, PreDoc Program Meyer/Neuro Sleep Baltimore, MD MedicalResearch.com: What is the background for this study? 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.

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.

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.

Blaiss, MD, FACAAI Executive Medical Director American College of Allergy, Asthma & Immunology Arlington Heights, IL 60005 MedicalResearch.com: Is this research important? Why or why not? Response: There has not been a comprehensive review of how allergic rhinitis impacts the adolescent population. Most studies put adolescents in with children and yet we know that how disease affects adolescents may be dramatically different than children. Adolescents is a difficult enough time with a chronic condition MedicalResearch.com: What is the key take-home message? Response: The symptoms associated with nasal and eye allergies can be different in adolescents compared with adults and children and lead to poor quality of life and impair learning in school. Adolescents with AR/ARC may experience difficulties falling asleep, night waking, and snoring, and generally have poorer sleep. Therefore health care providers need to aggressively control the adolescent’s allergic rhinitis.

Volkow MD Senior Investigator Laboratory of Neuroimaging, National Institute on Alcohol Abuse and Alcoholism National Institutes of Health, Bethesda, MD 20892 MedicalResearch.com: What is the background for this study? What are the main findings? Response: Findings from animal studies had shown that sleep deprivation increased the content of beta-amyloid in brain, which is a risk factor for Alzheimer’s disease.  We wanted to test whether this also happened in the human brain after one night of sleep deprivation. We found that indeed one night of sleep deprivation led to an accumulation of beta amyloid in the human brain, which suggest that one of the reasons why we sleep is to help clean our brain of degradation products that if not removed are toxic to brain cells.

Response: Previous research has shown that “night owls” (people who prefer the evening) have higher rates of diseases such as diabetes or high blood pressure.  We wanted to determine whether mortality risk was also higher in night owls. We used data from the UK Biobank of almost a half million people who were asked whether they were morning or evening types. We found that the night owls had a 10% increased risk of dying over a 6 ½ year period compared to the morning types, even after taking into account existing health problems.
Aging, Author Interviews, Circadian Rhythm, Sleep Disorders / 29.03.2018

MedicalResearch.com Interview with: “Woman sleeping” by Timothy Krause is licensed under CC BY 2.0Dr Gurprit S. Lall BSc, MSc, PhD, PGCHE, FHEA Medway School of Pharmacy Interim Deputy Head of School Senior Lecturer in Pharmacology Director of Graduate Studies (Research), University of Kent at Medway Chatham Maritime, Chatham, Kent MedicalResearch.com: What is the background for this study? What are the main findings? Response: Medical advancement in prevention and diagnosis of disease has increased life expectancy significantly, thus generating an ageing population far greater than previously seen.  Because of this, it is essential that we begin to understand the ageing process, together with the health implications associated with senescence.  Recent research has found that changes in the circadian clock, located in the brain, play a contributing role in the decline of many physiological and behavioural traits observed through the ageing process.  One example of this, which is commonly seen in the elderly is a decline in sleep-wake cycle regulation; typically presenting as disrupted sleeping patterns. The circadian clock, in mammals, possesses the ability to integrate our social lifestyle choices with the environmental day-night cycle to generate a 24-hour rhythm to which our physiological functions are synchronised.  It is this synchronisation that plays a vital role in regulating many of our behavioural outputs, such as sleeping-wake patterns.  This clock takes its strongest timing cue from the natural day night cycle governed by the duration of daily sunlight. Our study investigated the changes in the interpretation of this light signal by the circadian clock as we age and its impact on function.  We found that the clock became less responsive to light stimuli at both the level of clock cells and at driving behavioural activity.  We were able to narrow this down to changes in the proteins within cells that relay light information to the molecular time setting machinery.  In detail, light signals are relayed to the clock through an excitatory neurotransmitter called glutamate and this signal is predominantly relayed through NMDA receptors located on the surface of clock cells.  It is the configuration of the NMDA receptor that alters as we age and this leads to the clock becoming less responsive to light.

Prior, MD Professor in the Department of Medicine Division of Endocrinology and Metabolism University of British Columbia in Vancouver Dr. Prior has written the second edition of the award-winning book, Estrogen’s Storm Season—Stories of Perimenopause this year as an ebook on Google Play. MedicalResearch.com: What is the background for this study? Response: There is an urgent need for an effective therapy for perimenopausal hot flushes/flashes and night sweats (vasomotor symptoms, VMS). Although often considered “estrogen deficiency symptoms” VMS are common and very problematic for women in the menopause transition and who have not yet been one year without flow. About 23% of North American women are now in the perimenopausal age range. Surprisingly VMS are more common in perimenopause than in menopause; 9% of perimenopausal women have severe VMS as classified by the FDA, meaning more than 50 VMS per week of moderate to intense severity. The commonly used therapies for VMS in midlife women have not been proven more effective than placebo! That includes combined hormonal contraceptives (CHC) and menopausal-type hormone therapy (MHT) as well as the SSRI/SNRI anti-depressants and gabapentin. 
Author Interviews, Coffee, Sleep Disorders / 01.03.2018

MedicalResearch.com Interview with: Coffee being poured Coffee pot pouring cup of coffee. copyright American Heart AssociationJulia F. van den Berg, PhD Leiden University, Department of Clinical Psychology Leiden, The Netherlands  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Caffeine is the most used psychoactive substance worldwide, mostly consumed via coffee, energy drinks, tea and chocolate. Experimental studies have shown that caffeine can negatively affect sleep quality. The timing of caffeine consumption may play a role; the closer to bedtime, the more caffeine consumption is  likely to have a negative effect on sleep. We also wondered if chronotype, being a morning or evening person, would make a difference in the effect of caffeine on sleep. We sent out questionnaires on sleep quality, chronotype, and a detailed questionnaire on type and timing of caffeine use to 880 secondary education students (mean age 21.3 years). We found that for the entire group, the amount of caffeine per week was not associated with sleep quality, regardless of chronotype. However, when we divided the group into subgroups of students who did, and students who did not usually consume caffeine in the evening (after 6PM), we found something interesting. Only for students who did not consume caffeine in the evening (20% of the total sample), a higher total caffeine consumption per week was associated with poorer sleep, in spite of the fact that these students consumed a lot less  caffeine per week than the group who did consume caffeine in the evening. This suggests a self-regulatory mechanism: students who know they are sensitive to caffeine do not drink it in the evening, nevertheless, the caffeinated beverages they drink during the day do affect their sleep.

Wheaton, Ph.D. Epidemiologist Centers for Disease Control and Prevention National Center for Chronic Disease Prevention and Health Promotion Division of Population Health Epidemiology and Surveillance Branch Atlanta, GA  30341-3717 MedicalResearch.com: What is the background for this study? Response: Insufficient sleep among children and adolescents is associated with an increased risk for obesity, diabetes, injuries, poor mental health, and attention and behavior problems. In previous reports, CDC had found that, nationwide, approximately two thirds of U.S. high school students report sleeping <8 hours per night on school nights. CDC conducted this study to provide state-level estimates of short sleep duration on school nights among middle school and high school students using age-specific recommendations from the American Academy of Sleep Medicine (AASM). AASM has recommended that children aged 6–12 years should regularly sleep 9–12 hours per 24 hours and teenagers aged 13–18 years should sleep 8–10 hours per 24 hours for optimal health.

Lee, RN, CBSM, PhD Department of Family Health Care Nursing University of California at San Francisco San Francisco, California  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Sleep deprivation can adversely affect health and wellbeing in any patient population. In pregnancy, adverse outcomes may include preterm birth, longer labor, cesarean birth, and depression. We found that women with high-risk pregnancies were sleep deprived even prior to hospitalization. Our sample averaged 29 weeks gestation, and half reported getting only between 5 and 6.5 hours of sleep at home before hospital admission. Our sleep hygiene intervention strategies gave them more control over the environment in their hospital room, and they self-reported significantly better sleep than controls. Interestingly, both groups increased their sleep time to almost 7 hours at night, on average, in the hospital before they were discharged home.

MedicalResearch.com Interview with: “Video Game Addicts” by Michael Bentley is licensed under CC BY 2.0Dr. Marsha Novick, MD Associate professor of pediatrics and family and community medicine, Penn State College of Medicine  MedicalResearch.com: What is the background for this study? What are the main findings? Response: The results of this study solidify some well-established data concerning childhood obesity – namely that children who watch more television and have a more sedentary lifestyle are more likely to have an overweight or obese BMI compared with those who are more active. The survey results highlight some associations between increased technology use and difficulty with sleep quantity in children and adolescents. The data suggest:
  • ​​Increased technology use at bedtime, namely television, cell phones, video games and computers, is associated with a decrease in the amount of sleep children are getting. These children were more likely to be tired in the morning and less likely to eat breakfast.
  • Specifically, children who reported watching TV or playing video games before bed got an average of 30 minutes less sleep than those who did not, while kids who used their phone or a computer before bed averaged an hour less of sleep than those who did not.
  • The data also suggests that children with overweight or obesity were more likely to have trouble falling asleep and trouble staying asleep than their normal BMI counterparts
  • When children were reported by their parents to use one form of technology at bedtime, they were more likely to use another form of technology as well.

MedicalResearch.com Interview with: Jack Peltz, Ph.D. Clinical assistant professor in Psychiatry Rochester Medical Center MedicalResearch.com: What is the background for this study? What are the main findings? Response: Approximately 90% of high-school aged adolescents get either insufficient sleep during school nights or barely meet the required amount of sleep (ie, 8–10 hours) expected for healthy functioning.(1) In fact, sleep problems and insufficient sleep are so pervasive for adolescents that they could be considered an epidemic due to their adverse impact on adolescent mental and physical health.(2–5) As a result,addressing insufficient adolescent sleep represents a critical point of study and intervention. The growing body of evidence suggests that later school start times (SST), 8:30 AM or later as recommended by the American Academy of Pediatricians,6 convey multiple benefits on adolescents, including improved sleep, better mental and physical health, and improved academic outcomes.(7–10) This research, however, has focused on the direct effects of delaying school start times, or specifically how moving SST back directly predicts changes in an outcome (eg, mental health, academic achievement). This type of analysis precludes examining the important role that SST might play as a condition or context under which other sleeprelated processes take place. For instance, earlier school start times might exacerbate the impact of sleep-related processes on adolescent behavioral health outcomes. Thus, incorporating school start times as a larger contextual variable that might moderate models of sleep and adolescent functioning represents a gap in the literature and a unique opportunity to advance conceptual models. Accordingly, the current study examines the moderating role of school start times on the associations between sleep hygiene, sleep quality, and mental health.

Response: Our research focuses on the health of women as they age and transition from the childbearing period. During this time, women may be at increased risk for chronic health conditions such as diabetes and cardiovascular disease. As insufficient sleep is a modifiable behavior that is associated with these chronic health conditions, we wanted to examine how sleep duration and quality varies by menopausal status.
Author Interviews, Education, Pediatrics, Sleep Disorders, University of Michigan / 22.08.2017

MedicalResearch.com Interview with: [caption id="attachment_36583" align="alignleft" width="180"]Galit Dunietz, Ph.D., MPH Doctor of Philosophy Department of Neurology University of Michigan  Ann Arbor MI Dr. Dunietz[/caption] Galit Dunietz, Ph.D., MPH Epidemiologist, Sleep Disorders Center Department of Neurology University of Michigan Ann Arbor MI MedicalResearch.com: What is the background for this study? What are the main findings? Response: Insufficient sleep has a negative impact on health, cognition and mood and is linked to motor vehicle accidents. However, sleep loss in adolescents has become an epidemic and arises in part from biological processes that delay sleep and wake timing at the onset of puberty. This biology does not fit well with early school start times (before 8:30 a.m.). Despite recommendations from the American Academy of Pediatrics and the American Academy of Sleep Medicine to delay school start times, most schools in the U.S. have current start times before 8:30 a.m. In this nationally representative study of US parents of teens, we examined whether parents supported or opposed later school start times (after 8:30 a.m.). We also examined what may have influenced their opinions. We found that only about half of surveyed parents of teens with early school start times supported later school start times. Opinions appeared to depend in part on what challenges and benefits were expected to result from the change. For example, parents who expected an improvement in their teen’s academic performance or sleep quantity tended to support the change, whereas parents that expected negative impact on afterschool activities or transportation opposed delays in school start times.  We also found that parents had misconception about sleep needs of their adolescents, as the majority perceived 7-7.5 hours of sleep as sufficient, or possibly sufficient even at this young age when 8-10 hours are typically recommended.

Moon, M.D. Division Head, General Pediatrics Professor of Pediatrics University of Virginia School of Medicine Charlottesville, VA 22908 MedicalResearch.com: What is the background for this study? What are the main findings? Response: Approximately 3500 babies die suddenly and unexpectedly during sleep in the US every year. Even though there are safe sleep recommendations, many parents do not follow them because of misinformation or misconceptions. Therefore we tested 2 complementary interventions to promote infant safe sleep practices. The first was a nursing quality improvement intervention aimed at ensuring that mothers would hear key messages and that there was appropriate role modeling of safe sleep practices by hospital personnel. The second was a mobile health intervention, in which mothers received videos and text messages or emails with safe sleep information during the baby's first two months of life. We randomized mothers to receive either the safe sleep interventions or breast-feeding interventions (the control interventions). Mothers who received the mobile health intervention reported statistically significantly higher rates of placing their babies on their back, room sharing without bed sharing, no soft bedding use, and pacifier use, compared with mothers who received a control intervention. Although the nursing quality improvement intervention did not influence infant safe sleep practices, there was an interaction such that mothers who received both the safe sleep nursing quality improvement intervention and the safe sleep mobile health intervention had the highest rates of placing their babies on the back.

Deodhar, MD, MRCP, FACP, FACR Professor of Medicine Medical Director, Rheumatology Clinics Medical Director, Immunology Infusion Center Oregon Health & Science University  MedicalResearch.com: What is the background for this study? Response: The GO-ALIVE study (CNTO148AKS3001) is a multicenter, randomized, double-blind, placebo-controlled study of golimumab, an anti-TNFα monoclonal antibody, administered intravenously (IV), in adult patients with active ankylosing spondylitis (AS). The primary objective is to evaluate the efficacy of golimumab 2 mg/kg in patients with active AS by assessing the reduction in signs and symptoms of AS. The secondary objectives include assessing efficacy related to improving physical function, range of motion, health-related quality of life, and other health outcomes. A total of 208 patients who had a diagnosis of definite  ankylosing spondylitis (per modified New York criteria) and Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) ≥4, total back pain visual analogue scale (VAS) ≥4, and CRP ≥0.3 mg/dL were randomized.  Patients were treated with IV golimumab (n=105) at Weeks 0, 4, and every 8 weeks through Week 52 or placebo (n=103) at Weeks 0, 4, and 12, with crossover to IV golimumab at Week 16 and through Week 52.

Response: Chronic sleep and wakefulness disorders affect an estimated 50 to 70 million Americans, and long-term sleep deprivation has been associated with negative health consequences, including an increased risk of diabetes, hypertension, heart attack, stroke, obesity and depression. Sleep/wake cycles are regulated by melatonin, levels of which 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 in triggered. Melatonin levels typically decline with age, with a significant decrease after age 40. And as people age, their bodies may no longer produce enough melatonin to ensure adequate sleep. In addition to difficulties falling asleep, sleep in older populations can include fragmented and sustained sleep problems. Melatonin supplementation has been shown to promote and maintain sleep in older populations. In this study, we compared the pharmacokinetics (PK) profile of REMfresh®, a continuous release and absorption melatonin (CRA-melatonin), with that of a leading immediate-release melatonin (IR-melatonin) formulation.
