Goal 2: Reduce Human Disease

Developing approaches to the dissemination of behavioral weight loss programs

The Challenge is to make behavioral weight loss programs readily available to he many overweight and obese patients who need them. Behaivoral weight loss programs are effective in producing weight losses of 7-10% of initial body weight, which has been shown to have major beneficial effects on a number of diseases relevant to NHLBI--including hypertension and sleep apnea. However, at present, these programs are not widely ...more »

Goal 3: Advance Translational Research

DEVELOPMENT OF BIOMARKERS FOR SLEEP INSUFFICIENCY, CIRCADIAN DISRUPTION AND SLEEP DISORDERS

There is an urgent need to develop quantifiable biomarkers for acute sleep loss, chronic sleep insufficiency, circadian disruption and sleep disorders such as obstructive sleep apnea. These problems are highly prevalent but currently we do not have biomarkers to use for case identification, prognosis, or assessing response to therapy. There are currently small studies that indicate the feasibility. A recent workshop ...more »

Is this idea a Compelling Question (CQ) or Critical Challenge (CC)? : Critical Challenge (CC)

Details on the impact of addressing this CQ or CC :

The following will be the impact of addressing this critical challenge:

 

1. Having an assessment that can be used following a crash to assess the level of sleep loss of the driver.

2. Having a method to assess chronic sleep insufficiency as a potential pathogenetic process in patients with cardiovascular disease, hypertension, etc.

3. Having a method to estimate circadian phase so that in patients with chronic insomnia one can identify individuals with delayed sleep phase.

4. Having a technique to establish magnitude of circadian disruption to assess its role in pathogenesis of diseases such as cardiovascular disease.

5. Add a molecular biomarker to other techniques to screen for obstructive sleep apnea in high risk populations such as obese commercial drivers.

6. Utilize a biomarker signature to identify who with obstructive sleep apnea will be particularly at risk for downstream consequences such as cardiovascular disease.

7. Develop the equivalent of HbA1C to assess therapeutic response to CPAP

Feasibility and challenges of addressing this CQ or CC :

The first challenge is to identify a signature for each of these use cases. This will require initial studies in a small number of well phenotyped subjects with all the “-omic” techniques. Thereafter, these multiple cohorts, already available with blood samples, etc. and relative phenotype can be used for validation purposes.

Clinical Trials in Pediatric Sleep Disorders - Effect of adenotonsillectomy

Effect of adenotonsillectomy on behavioral and cardiovascular outcomes in children with primary snoring

Submitted by (@nhlbiforumadministrator)

Details on the impact of addressing this CQ or CC :

The recent NHLBI Childhood Adenotonsillectomy (CHAT) study showed highly significant behavioral improvements in children with obstructive sleep apnea syndrome . This study included children with an apnea hypopnea index as low as 2/hr. Many small or suboptimally controlled studies suggest that even primary snoring can affect behavior. If large randomized controlled trials confirm this finding, it will radically affect the treatment of the estimated 10% of children who snore.

Goal 2: Reduce Human Disease

What are the biological consequences of sleep loss or disruption and how can they best be avoided?

Arousals in obstructive sleep apena (OSA) are life saving, but the associated disruption of sleep is now thought to cause cognitive impairment, increased risk of high blood pressure and atherosclerosis, as well as glucose intolerance and metabolic syndrome. The mechanisms for these downstream effects, however, are not well understood. Can these specific pathophysiological mechanisms be identified, and can ways for mitigating ...more »

Details on the impact of addressing this CQ or CC :

By identifying the mechanisms by which sleep loss or disruption affects cognitive, cardiovascular, and metabolic function, we hope to find key regulatory points for which interventions may be developed. For example, if we can allow respiratory reflex responses to reopen the airway without EEG activation during OSA, we may be able to forestall some of the cognitive consequences of inadequate sleep. If we can prevent the autonomic responses associated with the EEG arousals and increases in respiratory drive, we may be able to block the repetiive elevations of blood pressure that lead to long term hypertension and accelerated atherosclerosis. If we can identify the reason for metabolic derangement associated with OSA, we may find, for example, that it is due to circadian misalignment and find ways to realign the sequence of metabolic events with the actual wake-sleep patterns of the patients. Finally, if we can potentiate the respiratory reflexes that re-establish the airway in OSA, without triggering the other components of arousals, we may be able to minimize or prevent the apneas. While current methods for treating OSA (e.g., CPAP and dental appliances) help many people, many others cannot tolerate these devices, and we require additional modes of therapy to mitigate the consequences of OSA.

Feasibility and challenges of addressing this CQ or CC :

The methods are currently available to address the questions that are raised above. The revolution in methods for evaluating the functions of neural circuits, using optogenetics and chemogenetics, for example, should allow us to identify brain circuits that are involved in the various components of the reflex responses to apnea. We can examine their neurotransmitters and receptors, and design new therapies based on manipulating CNS circuitry. Methods for assessing ongoing autonomic, respiratory, and metabolic responses in genetically mutated mouse modesl may require further miniaturization of various physiological methods, but this field is also rapidly advancing. Finally, methods for examining ongoing changes in neuronal activity in the living brain of awake mice are rapidly advancing.

Can Psychological Science Improve Weight Loss?

Will sensitivity to the psychological aspects of obesity, including lifestyle priorities and motivations, improve the efficacy of long-term effectiveness of weight loss and obesity prevention interventions?

Submitted by (@nhlbiforumadministrator)

Is this idea a Compelling Question (CQ) or Critical Challenge (CC)? : Compelling Question (CQ)

Details on the impact of addressing this CQ or CC :

A primary focus on principles of psychology may result in significantly improved control of the obesity epidemic. Effective interventions could reduce the risk of diabetes, sleep apnea, and hypertension. This research could also affect clinical practice guidelines for weight loss and obesity treatment.

Feasibility and challenges of addressing this CQ or CC :

Psychological science has been successful in developing effective treatments for a number of conditions, including sleep disorders, depressive symptoms, anxiety and phobias. Many of the behavioral principles employed in such interventions (e.g., cognitive restructuring, motivational methods) could be translated for the prevention and treatment of obesity within a reasonable time frame. Additional attention should be directed to the needs of population subgroups in which obesity is most prevalent.

In their Viewpoint article on weight loss intervention research, Pagoto and Appelhans (JAMA, 2013, see attachment) question whether a continued focus on dietary factors in research on weight loss and obesity is warranted. Their commentary raises the importance of attention to the individual psychological characteristics that influence adherence to weight loss interventions rather than dietary composition.

Can At-home sleep studies change the rural area diagnosis of obstructive sleep apnea

At home sleep tests or personal monitors (PM) have been shown to effectively provide an adequate diagnosis of OSA with the proper pre-screening tests and evaluation. These methods can be adopted by hospitals and if used effectively can save money to the patients and healthcare facility. With the Affordable Healthcare Act the focus is on providing quality care for less money, but many hospitals are slow to adapt. Sleep ...more »

Details on the impact of addressing this CQ or CC :

Pediatric sleep experts agree that there appears to be a mini-epidemic of narcolepsy in children currently, characterized by acute onset of disease with severe symptoms and difficult to control cataplexy, in very young children. No drugs are approved for treatment of cataplexy in children, and drugs typically used in adults are not FDA-approved for use in children. A multicenter trial would be needed in order to accumulate sufficient cases for a randomized controlled trial.

Sleep Apnea

The general area is that of preoperative risk management of sleep apnea patients undergoing major surgery. This field is burgeoning with clinical activity. A large amount of healthcare dollars are expended annually in order to detect sleep apnea and offer therapy that is of unproven value.

Details on the impact of addressing this CQ or CC :

The existing data shows that sleep apnea may be moderate risk factor for poor outcomes and complications from surgery but the magnitude of the risk and the degree to which sleep apnea therapy modifies this risk is not known and won’t be determined without larger scale trials. This field desperately needs some randomized trials to answer some of these questions. Trials which randomize patients undergoing some major surgery to a sleep apnea treatment with CPAP if OSA is diagnosed before surgery  vs. treating with CPAP after surgery in the post operative period is one such study that could be performed.

If this question has an answer, it would help an unknown number of persons by once again providing effective treatment for sleep apnea. I find fatigue is building again, as it did before I was diagnosed and treated.

 

It may be simply a matter of a different style of mask, but it appears ideas on what kind are a bit sparse on the ground.

Feasibility and challenges of addressing this CQ or CC :

One would need a sampling of persons with lower teeth (some, or all) who also have sleep apnea. One would have to determine whether indeed, there is a deterioration in quality of treatment, and if the number of lower teeth are a factor. Does the form of apnea make a difference? Does age or body weight play a part?

 

This is not exactly couched in academic, medical terms, but it is still a valid question. Its solution, or if a solution already exists, it's distribution among sleep physicians, would help those who experience this combination of circumstances.
