Sleep Disorders and Their Cardiovascular Correlates in Atahualpa.

InsomniaHypersomnia3 more

Little is known on the prevalence of sleep disorders and their role in the increased prevalence of cardiovascular diseases in the developing world. We To assess the prevalence of major sleep disorders in a rural South American population, and to determine whether these conditions are associated with a poor cardiovascular health or with the occurrence of stroke or ischemic heart disease. This is a three-phase, population-based, door-to-door survey in Atahualpa. During phase I, all residents aged ≥40 years will be screened with validated Spanish versions of five questionnaires to evaluate major sleep disorders. In phase II, neurologists will examine persons suspected of having a sleep disorder and a random sample of negative individuals to assess the prevalence of these conditions and to validate the accuracy of questionnaires. In phase III, patients with a confirmed sleep disorder will undergo nocturnal polysomnography for achieving a more specific diagnosis. The occurrence of sleep disorders will be correlated with the cardiovascular health of the population as well as with the presence of stroke and ischemic heart disease. This epidemiological study may prove cost-effective in improving sleep conditions of people living in rural areas of developing countries, and may be used as a model for the evaluation of sleep disorders and their cardiovascular correlates in these populations.

Relationship Between Perioperative Related Factors and Inflammatory Markers and Postoperative Delirium...

Preoperative Sleep DisorderPreoperative Anxiety2 more

Perioperative neurocognitive impairment, including postoperative delirium (POD), is common in older patients after anesthesia and surgery and is associated with poorer short- and long-term outcomes, including worsening cognitive decline, surgical Complications, increased risk of hospitalization, and death after cardiac and noncardiac surgery. POD is more common with age, occurs in up to 65% of elderly patients, and increases in patients with mild cognitive impairment. As more and more older adults undergo surgery and anesthesia, POD has become a major global health challenge requiring urgent attention. Prevention strategies involving multidisciplinary perioperative interventions may have some benefit overall, but the impact on POD remains uncertain. Known inflammatory responses may be associated with adverse outcomes such as neurocognitive dysfunction and cancer recurrence after major surgery. Different anesthesia methods, the regulation of anesthesia drugs on postoperative inflammatory response has been confirmed in vitro, but its clinical significance is still unclear. Therefore, exploring the risk factors of inducing POD has important clinical significance for the early prevention of POD. Second, a recent study found that the incidence of POD was significantly higher in patients whose sleep cycle was disturbed during hospitalization. Animal experiments found that after 5 hours of sleep deprivation in adult mice, the number of dendritic spines in CA1 neurons in the hippocampus was reduced, and the length of dendrites was significantly shortened, which damaged the synaptic transmission of the central nervous system, and significantly improved memory and cognitive function. Damaged. And many studies have investigated whether bispectral index (BIS)-guided anesthesia is associated with a reduced risk of POD, compared with "standard-of-care" anesthesia or the use of goal-directed end-tidal volatile agent concentrations, the reasoning is that the use of BIS-guided anesthesia results in less anesthesia exposure, and therefore "light" anesthesia may reduce the incidence of postoperative POD compared to "deep" anesthesia. However, this conclusion is still controversial. The study of Anshentong et al. has confirmed that deep anesthesia with BIS maintained at 40-49 can delay postoperative recovery time, reduce the level of inflammatory factors and the incidence of early postoperative cognitive impairment, and reduce the incidence of early postoperative cognitive impairment. Brain damage. Therefore, although age is known to be the main correlative factor for POD, different depths of anesthesia may cause different stress responses in patients, resulting in different release of inflammatory factors. An additional risk factor may be preoperative psychiatric symptoms, and assessment of mental status is often overshadowed by concerns about multiple comorbidities in older adults. Anxiety disorders are one of the prominent psychiatric symptoms in older adults. very common. Preoperative anxiety is defined as an unpleasant restless or tense state secondary to patient concerns about illness, hospitalization, anesthesia, surgery, or the unknown. Studies on the relationship between preoperative anxiety and POD also vary in consistency due to the characteristics of different populations. Many of the current studies are mostly single-center with limited sample size, which may have a certain bias in the conclusions. Therefore, the investigators designed and planned to conduct a multi-center, large-sample cohort study to determine the impact of perioperative related factors and inflammatory markers on elderly patients undergoing non-cardiac major surgery .

Determining the Role of Sympathetic Activity in the Impact of Combat Injury on Sleep and Cardiovascular...

HypertensionCardiovascular Diseases4 more

The goal of this observational study is to learn about the long-term health of United States military service members who were injured during combat. The main questions it aims to examine are: How does the severity of a combat injury impact 1) cardiovascular risk, 2) the sympathetic nervous system and arrhythmias, 3) blood pressure, and 4) sleep disorders? Are self-reported mental health symptoms related to sympathetic nervous system hyperactivity, sleep disorders, and cardiovascular risk in combat-injured service members? This study will recruit from a sample of participants in another research study called the Wounded Warrior Recovery Project (WWRP) who 1) agreed to be contacted about future research studies and 2) have a record of a combat injury within the Injury Severity Score ranges required for this study. Participants will: Provide demographic information and a medical history review Visit a local laboratory for biometrics measurements and to provide blood and urine samples Wear an ambulatory electrocardiogram monitor for 24 hours per day for seven consecutive days Wear a home sleep test monitoring device for one night Wear a blood pressure monitor for 24 consecutive hours on the day after the home sleep test At the end of the study, participants will be asked to mail back the home sleep test and blood pressure monitors. Prepaid package materials will be provided.

Evning Exposure to Computer Screen Disrupts Sleep, Attention and Biological Rhythms

Sleep Disorder

Light exposure is on the rise in recent years. In large part because of unintentional illumination from screens that emit light directly into the eyes. Millions of computers, tablets, televisions, and smart-phones are sold worldwide every month and the usage time of these devices is increasing constantly. Today, people are exposed to ongoing light exposure from these device screens, emitting short wave length (SWL) during day and night hours, whether as active or passive users. In sum, artificial light at night (ALAN) seem to affect human circadian rhythmicity (melatonin and thermoregulation) and sleep, with two major factors. First, wavelength of light, with SWL being most detrimental to sleep and rhythms, when compared to LWL (Brianard et al., 2001). Second, a dose-response relationship exists between increasing light intensity and poorer sleep/circadian rhythms (Brianard et al., 1988; West et al., 2011). Based on existing knowledge, we hypothesize that when compared to long wavelength LWL illumination, short wavelength SWL illumination from computer screen will have a more damaging effect on melatonin (MLT) production and secretion, interfering body temperature regulation and affecting sleep quality, efficiency and sleep architecture. In addition, we hypothesized that intensity of the screen illumination will play another important factor on these outcomes, we assume that high intensity compared to low intensity will have more damaging effect on: melatonin, thermoregulation and sleep.

Light Therapy on Sleep Quality in Dialysis Patients

Chronic Renal FailureSleep Disorder2 more

Sleep disorders are common in dialysis patients. At present, the management of insomnia in patients with chronic renal failure is not significantly different from that of the general population, which focuses on the management of co-factors, sleep hygiene, and cognitive-behavioral therapy. Light therapy is a paramedical practice that involves exposing a patient to a light intensity greater than 5000 Lux (usually 10,000 Lux) for 30 minutes in the morning between 7:00 and 8:30. Its impact is partly mediated by an improvement in the nycthemeral cycle of melatonin. Light therapy may improve sleep disorders and anxious-depressive elements as suggested in the literature. This technique has not yet been evaluated in dialysis patients, whereas easy to set up.

Sustainable Methods, Algorithms, and Research Tools for Delivering Optimal Care Study

Obstructive Sleep Apnea of AdultInsomnia4 more

Sustainable Methods, Algorithms, and Research Tools for Delivering Optimal Care Study (SMART DOCS) was designed to develop and evaluate a new approach (patient-centered outcomes and coordinated-care management [PCCM]) for the diagnosis and treatment of sleep disorders. Specialized and pertinent information and resources regarding sleep disorder management were developed and made available through an online portal, allowing patients to make informed health care decisions, and providers to assist patients in achieving what they feel are the most important goals regarding their care. Half of participants were randomized into the conventional diagnosis and treatment (CONV) arm and the other half into the patient-centered outcomes and coordinated-care management (PCCM) arm. Validated objective and subjective assessment measures were administered at intervals throughout a 13 month participation period in both the CONV and PCCM arms to determine whether the new PCCM approach for sleep medicine results in increased patient satisfaction, quality of care, and improved health outcomes. Qualifying participants were 18 years of age or older and presenting with a new sleep disorder. Patients received no monetary compensation.

Light Sensitization Study

Chronobiology DisordersCircadian Rhythm Disorders2 more

Circadian rhythm disorders are a class of sleep disorders characterized by misalignment between the timing of sleep and the timing of rhythms driven by the biological clock. Light therapy can effectively treat these disorders, but the intensity and duration of light exposure required to do so has limited its practical use. In this study the investigators will test whether pre-exposure to dim light may enhance the response of the circadian system to light therapy. If so, this could result in shorter treatments that would have greater practical applications.
