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?

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.

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 »

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

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.

HEALTH CARE DISPARITIES IN DIAGNOSIS AND TREATMENT OF COMMON SLEEP AND CIRCADIAN DISORDERS

There is evidence of a higher prevalence of sleep and circadian disorders in different ethnic groups. This is true for both adult and pediatric subjects. There is also evidence that minority populations in lower socioeconomic groups do not seek evaluation for sleep disorders as frequently as other segments of our population. There is also evidence that they are less adherent to treatments such as nasal CPAP for obstructive... more »

Sleep disorders are more common in minority populations. Moreover, these populations have higher rates of the known consequences of these disorders such as stroke, myocardial infarction, hypertension, resistant hypertension. Despite this, current population studies such as the Sleep Heart Health Study have included only a very small percentage of African Americans. The impact of this would be the following:

a. Elucidating the basis of barriers to case identification in these group
b. Designing specific intervention to overcome these barriers.
c. Developing methods to improve adherence to therapy in this group.
d. Removing sleep and circadian disorders as a risk factor for consequences such as stroke, cardiovascular disease and resistant hypertension in minority populations

Feasibility and challenges of addressing this CQ or CC

There is a developing interest in this area in the field of circadian and sleep research. There is a developing knowledge base about health disparities in sleep and circadian disorders. Minority institutions such as Morehouse have developing programs in this area. We also have mobile technology that facilitates study of sleep and circadian disorders in minority populations.

Goal 2: Reduce Human Disease

UNDERSTANDING SLEEP AND CIRCADIAN DISORDERS AT A BASIC MECHANISTIC LEVEL

We need to understand sleep and circadian disorders at a more mechanistic level. This applies to both the pathogenesis of these disorders and to their impact on health. New neurobiological and molecular tools facilitate this research. The focus needs to be not only in brain but also the impact of these disorders on future of peripheral organs.

Details on the impact of addressing this CQ or CC

Much of the research on the consequences of sleep/circadian disorders has focused on their consequences or behavior. This type of research needs to be continued and there are new opportunities in this area. These behavioral studies need to be established in model systems to parallel studies in humans. In addition, new neurobiological approaches, including optogenetics and use of DREAD, provide new tools for this investigation. Moreover, we now have powerful molecular tools to evaluate effects of sleep/circadian disorders both in humans and animal models. These include microarrays, RNA seq, etc. Moreover, genetic studies, e.g., in restless legs syndrome, have identified gene variants conferring risk for the disorder. We do not know, however, how these particular genes are involved in the pathogenesis of the disorder or whether they represent potentially targets for drug intervention. There is a need for studies both in animal models and in humans to elucidate the function of these genes. Studies in other areas are obtaining stem cells from biopsies in patients and then turning these into relevant target cells such as neurons to elucidate gene function using in vitro approaches.
The impact of this effort will be the following:

a. Taking our understanding of pathogenesis of sleep and circadian disorders to a new level.
b. Understanding the consequences of sleep and circadian disorders on different end organs at a more in-depth molecular level.

Feasibility and challenges of addressing this CQ or CC

The sleep and circadian field have access to all the major cells systems for these studies—C. elegans, aplysia, Drosophila, zebra-fish, mice, etc. Moreover, there are already gene variants identified in human studies which require follow-up functional studies. The field has the expertise in all of the techniques described above. Moreover, there are more validated animal models for many of the common sleep disorders. Thus, this new approach is very feasible.

SLEEP DISORDERS AS A MODIFIABLE RISK FACTOR FOR CHRONIC DISEASE

There is developing evidence that sleep disorders, in particular obstructive sleep apnea and inadequate sleep, can influence the course of other chronic diseases. Observational studies show that CPAP treatment of patients with pre-diabetes who have OSA reduces the incidence of future diabetes. Moreover, animal and human data indicate that insufficient sleep and sleep apnea can affect the rate of progression of neurodegenerative... more »

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

Details on the impact of addressing this CQ or CC

This question will have considerable impact. Sleep apnea is an independent risk factor for insulin resistance. Moreover, observational studies show that treatment of OSA reduces the rate of future diabetes compared to that which occurs in untreated OSA. Therefore, identifying OSA and treating this could have a profound impact on reducing the rate of diabetes, i.e., a preventative strategy.

Both sleep loss and obstructive sleep apnea have also been shown to be risk factors for subsequent development of Alzheimer’s disease. This has been shown in mouse models and in epidemiological studies to address whether insufficient sleep and sleep apnea are independent risk factors for development of Alzheimer’s disease, in particular accelerating their onset. Determining whether this is so and whether interventions to treat these sleep disorders delay onset of diabetes and Alzheimer’s disease would have profound public health significance.

Feasibility and challenges of addressing this CQ or CC

These disorders are extremely common so that recruitment of subjects is not challenging. Moreover, new technology reduces protocol burden to assess individuals. All studies can be done in the patients’ home. There are existing cohort studies focused on diabetes and the Alzheimer’s Center program that could be used for these studies. Thus, the studies are extremely feasible in the near term.

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.

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.

DEVELOPMENT OF A PERSONALIZED APPROACH TO SLEEP AND CIRCADIAN DISORDERS

There is developing evidence of major individual differences in pathways to different common sleep disorders such as obstructive sleep apnea.

Details on the impact of addressing this CQ or CC

There is a strong rationale for application of a personalized approach to sleep disorders. This requires approaching this question using multiple domains as in other areas of medicine—clinical features, physiological factors, application of the –omic approaches, genetics. The impact of this will be several:

a. A new way to classify sleep disorders.
b. Identification of subgroups of patients with apparently the same disorder who will have different outcomes of therapy.
c. Identification of subgroups of patients who will have different approaches to diagnosis.
d. Identification of subgroups of patients with apparently the same disorder who will have different therapeutic approaches.

Feasibility and challenges of addressing this CQ or CC

These sleep and circadian disorders are extremely common. There is a risk infrastructure for this type of research based on the large number of accredited sleep centers in the United States that could be used for subject recruitment and who can adopt similar techniques. There is also a rich set of data obtained from sleep studies that could be used to identify new patterns that reflect different subgroups of subjects. These studies need to be based on clinical populations of patients who present with the different disorders rather than on population-based cohorts.

If my doctors are correct, patients like myself are at high-risk. Before we die, we will need expensive hospital or nursing home based care. If some one can develop a mask or device that will work, he or she will literally save lives and reduce the financial burden on families, communities and hospitals.

Feasibility and challenges of addressing this CQ or CC

This shouldn't be difficult research. We're talking about an air delivery system, not a cure for cancer or AIDS. The challenge is that this is not a prestige issue. There won't be a lot of research centers spending on on this.

Yet it could save lives and reduce healthcare costs. Maybe this research could be conducted as a joint project of associations for ENT doctors, cardiologists and dentists.

Goal 2: Reduce Human Disease

What causes the structural abnormalities that cause sleep apnea, and how can they be prevented?

It is estimated that up to 28% of the population suffer from sleep apnea, which impairs functioning and reduces quality of life, while increasing risk of accidents and a variety of cardiovascular, metabolic, and neuropsychiatric diseases. A large portion of sleep apnea cases are caused by abnormal oro-nasal-maxillo-mandibular features that result in crowding of the upper airway, making it vulnerable to collapsing or... more »

Details on the impact of addressing this CQ or CC

Obstructive sleep apnea (OSA) is a common condition, which causes chronic fatigue and daytime sleepiness, as well as cognitive impairments affecting learning, concentration, and memory. Over the long term, it increases many health risks, including accidents, cardiovascular disease, and depression. OSA is characterized by partial, or complete, blockage of the airway during sleep, so that breathing repeatedly pauses or airflow is limited, causing repeated arousals from sleep. It is usually secondary to a narrow, or collapsible, airway due to either 1) obesity or overweight, or 2) abnormal morphology of the mandible or maxilla bones, which crowds facial structures, such as the tongue and nose, narrowing the pharynx. The causes of obesity are already being well studied, but there is relatively little research on the etiology of the structural abnormalities involved in OSA. Abnormalities of facial structure are widespread in the population causing, not only OSA, but also orthodontic problems that require many to get braces or have wisdom teeth extracted, and widespread temporomandibular joint (TMJ) problems. However, multiple studies have documented that these abnormalities are almost completely absent from populations living a preindustrial, agrarian or forager, lifestyle, making them a “disease of civilization”. In particular, the abnormalities are associated with consumption of a modern diet of processed foods during prenatal, infant, and early childhood development.

Feasibility and challenges of addressing this CQ or CC

Current evidence implicates three factors in the development of these structural abnormalities: prenatal maternal nutrition (especially vitamin K2 status), breastfeeding vs. bottle-feeding, and frequency of consumption of tough foods after weaning (which provides exercise to the jaw). We need to form a large cohort and study orthodontic development prospectively from fetal development through mid-childhood, with data on diet, feeding practices, and physiological measures of nutrient status. Measurement methods are available using existing technologies to collect the necessary data on each of these measures. Determining the causes responsible for these structural abnormalities will enable further research to demonstrate effective methods of preventing them. Given that many patients with OSA are rendered so miserable by it that they undergo maxillomandibular advancement surgery to correct it, an expensive procedure with a lengthy recovery period, prevention would be a far better solution. This research will move us a big step closer to a future without sleep apnea and its formidable collection of negative effects on health and functioning.

Sleep Apnea - Diagnostic Test

The notion that in order to be treated with CPAP for sleep apnea you first must have a diagnostic test, which involves either a sleep laboratory or a home study, needs to be examined.

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

Details on the impact of addressing this CQ or CC

This idea is far reaching and possibly ahead of the curve a bit but it represents a direction that the sleep apnea field eventually should explore. Consider developing a clinical diagnosis of sleep apnea based on clinical symptoms and exam findings and then randomized those patients meeting the definition to a trial of autocpap for 3 months or to a traditional evaluation (home diagnostic test then APAP) for 3 months. Close follow up is necessary but with wireless telephony now available for CPAP and estimates of AHI available through CPAP adherence downloads, this study is feasible. If such a case diagnosis of sleep apnea can be developed (and I believe it can), then many more patients may be able to be treated. This approach, if successful, would shake-up the field considerably and potentially opens up treatment to many more OSA sufferers.
