Insomnia Symptoms

AbstractInsomnia is the most prevalent sleep disorder and frequently co-occurs with obstructive sleep apnea (OSA), a chronic disease characterized by repetitive pauses of breathing during sleep due to obstructions of the upper airways. The link between lifestyle and sleep quantity and quality is an area of intensive research, however data exploring associations between lifestyle habits and insomnia symptoms are still scarce. The aim of the present study was to investigate the potential association between the level of adherence to the Mediterranean lifestyle (ML), a healthy lifestyle pattern incorporating the prudent Mediterranean diet, adequate physical activity and healthy sleep habits, and insomnia presence and severity. The study sample consisted of 243 adult patients with polysomnography-diagnosed OSA. Participants’ insomnia-related disorders were evaluated through the Athens Insomnia Scale (AIS), an 8-item index ranging from 0 (absence of any sleep-related problem) to 24 (severe degree of insomnia); AIS values of > 6 were used to establish the diagnosis of insomnia. All patients were evaluated with regard to anthropometric indices and lifestyle habits, and adherence to the ML was estimated through the MEDLIFE index, a 28-item index ranging from 0 to 28, with higher values indicating greater proximity to the healthy lifestyle of the Mediterranean region. An inverse correlation was observed between the MEDLIFE index and total AIS (rho = -0.22, p = 0.001), as well as most individual components of AIS, including difficulty in sleep induction (rho = -0.14, p = 0.03), awakenings during the night (rho = -0.2, p = 0.008), short sleep duration (rho = -0.16, p = 0.01), low quality of sleep (rho = -0.13, p = 0.05), low well-being during the day (rho = -0.16, p = 0.02), and low functioning capacity during the day (rho = -0.15, p = 0.02). Patients with insomnia (AIS > 6), compared to those without (AIS ≤ 6), exhibited lower MEDLIFE index values [13 (11–15) vs. 14 (12–15), P = 0.002], had more severe OSA as assessed by the apnea-hypopnea index (AHI) [55 (24–87) vs. 35 (17–57) events/hour, P < 0.001] and tended to have higher body mass index (BMI) [35.0 (30.6–39.7) vs. 32.4 (29.5–38.6) kg/m2, P = 0.06]. According to logistic regression analysis, MEDLIFE index was inversely associated with the presence of insomnia (OR: 0.89, 95%CI: 0.80–0.99, P = 0.04) after adjustment for age, sex, smoking, BMI, daily energy intake and AHI. In conclusion, a higher adherence to the ML is inversely associated with insomnia presence and severity in patients with obstructive sleep apnea. Future research should assess whether this association applies in other samples, as well as whether the ML could be an efficient therapeutic tool alleviating or treating insomnia symptoms.

Objective: The aim of this research was to assess the relationship between prevalence and severity of obstructive sleep apnea (OSA) and insulin resistance among patients with increased risk of OSA without diabetes mellitus. Method and materials: our study group involved 102 individuals with suspected OSA, mean age 53.02 ± 12.37 years. Data on medical history, medication usage, sleep habits, sleep quality and daytime sleepiness, were obtained using questionnaires. All patients underwent standardized full night polysomnography. Serum fasting insulin and glucose concentration were analyzed, the homeostatic model assessment-insulin resistance (HOMA-IR) index was calculated. Results: polysomnographic study indicated that in the group with OSA mean values of apnea–hypopnea index (AHI), oxygen desaturation index (ODI), duration of SpO2 < 90% and average desaturation drop were significantly higher compared to the group without OSA, while the minimum SpO2 was significantly lower. The carbohydrate metabolism parameters did not differ within those groups. Significantly higher fasting insulin concentration and HOMA-IR index were found in the group with AHI ≥ 15 compared to the group with AHI < 15 and in the group with AHI ≥ 30 compared to the group with AHI < 30. Higher AHI and ODI were independent risk factors for higher fasting insulin concentration and higher HOMA-IR index. Increased duration of SpO2 < 90% was an independent risk factor for higher fasting glucose concentration. Conclusions: Individuals with moderate to severe OSA without diabetes mellitus had a higher prevalence of insulin resistance.

Abstract Introduction Specialized health care guidelines for children with Down Syndrome (DS) published by the American Academy of Pediatrics (AAP) provided specific recommendations based on the higher risk needs of individuals with DS. Obstructive sleep apnea (OSA) is reported to be present in 50–79% of individuals with DS. According to the AAP guideline, all individuals with DS should have a polysomnography (PSG) evaluating for OSA by 4 years old and then screened by history and physical exam annually thereafter. An interim analysis of an ongoing Down Syndrome Research study was evaluated to determine rate of adherence to these guidelines. Methods The Dimensional, Sleep, and Genomic Analyses of Down Syndrome to Elucidate Phenotypic Variability study enrolled down syndrome patients 30 months and older, as well as first degree relatives to participate. Patients completed a standardized clinical sleep interview, childhood sleep habits questionnaire and was asked to complete 2 week sleep diary, actigraphy and polysomnography. We aimed to characterize the rate of PSG completion by 4 years of age, number of research PSGs completed and rate of OSA identified on research PSG. Results A total of 31 patients were consented. The median patient age was 10 years old with a slight female predominance (15F:12M). 27 patients completed the sleep interview and 19 successfully completed a scorable polysomnography. Only 7 patients had completed a PSG previously by age of 4 years. 11 of 19 studies demonstrated obstructive sleep apnea ranging from mild to severe severity (1.7–42.5/hr). REM AHI (range 1.2–58.2/hr, mean 19/hr and median 12.3/hr) demonstrated increased severity. Conclusion Despite AAP guidelines recommending universal PSG evaluation by the age of 4 years of age, only 26% of patients interviewed has a PSG successfully completed previously. Additional recommendations by AAP include yearly surveillance of symptoms although there is poor correlation between parent report and polysomnogram results. Of the 19 research completed PSGs, 58% demonstrated OSA with the mean and median results consistent with moderate to severe OSA and worsening during REM sleep. Improved effort to successfully obtain PSG in this population is needed. Further study is ongoing to evaluate the relationship to other health and cognitive outcomes. Support (if any) NIMH

Apnea Syndrome

Obstructive Sleep Apnea Syndrome (OSAS) is a sleep disorder characterised by repetitive episodes of upper airway obstruction (apnea) or reduced airflow (hypopnoea) despite persistent respiratory effort. Apnea is defined as the cessation of breathing for at least 10 seconds during sleep, while hypopnoea is defined as at least 30% reduction in airflow for 10 seconds associated with oxygen desaturation and sleep fragmentation. The presence in the general population is about 4%. The principal symptoms are: excessive daytime sleepiness (EDS), snoring, dry throat, morning headache, night sweats, gastro-esophageal reflux, and increased blood pressure.Long term complications can be: increased cardio-cerebrovascular risk and cognitive impairment such as deficiency in attention, vigilance, visual abilities, thought, speech, perception and short term memory.Continuous Positive Airway Pressure (CPAP) is currently the best non-invasive therapy for OSAS.CPAP guarantees the opening of upper airways using pulmonary reflexive mechanisms increasing lung volume during exhalation and resistance reduction, decreasing electromyografical muscular activity around airways.The causes of cognitive impairments and their possible reversibility after CPAP treatment have been analysed in numerous studies. The findings, albeit controversial, show that memory, attention and executive functions are the most compromised cognitive functions.The necessity of increasing the patient compliance with ventilotherapy is evident, in order to prevent cognitive deterioration and, when possible, rehabilitate the compromised functions, a difficult task for executive functions.

Apnea Syndrome

Surgical techniques for obstructive sleep apnea syndrome (OSAS) constantly evolve. This study aims to assess the effectiveness and safety of a new surgical approach for an OSAS pharyngoplasty with a dorsal palatal flap expansion (PDPFEx). A total of 21 participants (mean age 49.9; mean BMI 32.5) underwent a type III sleep study, an endoscopy of the upper airways, a filled medical history, a visual analog scale for snoring loudness, an Epworth Sleepiness Scale, and a Short Form Health Survey-36 questionnaire. A follow-up re-evaluation was performed 11 ± 4.9 months post-operatively. The study group (4 with moderate, 17 with severe OSAS) showed an improvement in all measured sleep study characteristics (p < 0.05), apnea-hypopnea index (pre-median 45.7 to 29.3 post-operatively, p = 0.009, r = 0.394), oxygen desaturation index (pre-median 47.7 and 23.3 post-operatively, p = 0.0005, r = 0.812), mean oxygen saturation (median 92% pre-operatively and median 94% post-operatively, p = 0.0002, r = 0.812), lowest oxygen saturation (p = 0.0001, r = 0.540) and time of sleep spent with blood oxygen saturation less than 90% (p = 0.0001, r = 0.485). The most commonly reported complications were throat dryness (11 patients) and minor difficulties in swallowing (5 patients transient, 3 patients constant). We conclude that a PDPFEx is a promising new surgical method; however, further controlled studies are needed to demonstrate its safety and efficacy for OSAS treatment in adults.

Background: Obstructive sleep apnea (OSA) is caused by partial or complete obstruction of the upper airways. Corrective surgeries aim at removing obstructions in the nasopharynx, oropharynx, and hypopharynx. OSA is associated with increased risk of various metabolic diseases. Our objective was to evaluate the effect of surgery on the plasma metabolome. Methods: This study included 39 OSA patients who underwent Multilevel Sleep Surgery (MLS). Clinical and anthropometric measures were taken at baseline and 5 months after surgery. Results: The mean Apnea Hypopnea Index (AHI) significantly dropped from 22.0 &plusmn; 18.5 events/hour to 8.97 &plusmn; 9.57 events/hour (p-Value &lt;0.001). The Epworth&rsquo;s sleepiness Score (ESS) dropped from 12.8 &plusmn; 6.23 to 2.95 &plusmn; 2.40 (p-Value &lt;0.001) indicating success of the surgery in treating OSA. Plasma levels of metabolites, phosphocholines (PC) PC.41.5, PC.42.3, ceremide (Cer) Cer.44.0, and triglyceride (TG) TG.53.6, TG.55.6 and TG.56.8 were decreased (p-Value&lt;0.05) whereas lysophosphatidylcholines (LPC) 20.0 and PC.39.3 were increased (p-Value&lt;0.05) after surgery. Conclusion: This study highlights the success of MLS in treating OSA. Treatment of OSA resulted in improvement in metabolic status that was characterized by decreased TG, PCs and Cer metabolites post-surgery indicating that the success of the surgery positively impacted the metabolic status of these patients.

Signal Processing Techniques

Sleep is judgmental to health and well-being. Deficient quality sleep is similar with a wide range of negative outcomes varies from schizophrenia to cardiovascular disorders. Obstructive sleep apnea is one of the sleep disorders. In order to identify the various syndromes the signals are need to record by using the sensors. Sleep signals are recorded by using the polysomnography (PSG) labs which is the old traditional and gold standard for recording the sleep signals. PhysioNet is a large online medical database that consists of a large collection of recordings of various physiological signals. PhysioNet database consist of sleep apnea database available. Physionet website is a universal service, physionet resource supported by the national institute of health’s National Institute of Biomedical Imaging and Bioengineering (NIBIB) and National Institute of General Medical Sciences (NIGMS). This survey paper aims to bring the different Signal Processing Techniques for Removal of Various Artifacts from Obstructive Sleep Apnea Signals to identify sleep apnea syndrome, because pre-processing is most effective and efficient to reduce unwanted signals from the original sleep signals. While recording the sleep apnea signals various artifacts records along with raw signals either directly or indirectly due to the internal and external sources like Power line interference, Muscle contractions, Electrode contact noise, Motion Artifacts, Baseline wandering, Noise generated by electronic circuits, while breathing and coughing, body position movements etc, and they need to be eliminated in order to acquire genuine health information. So in order to remove there artificats from the sleep signals the signal processing techniques (filtering techniques) are predominantly used for pre-processing of the sleep signals and have been executed in a wide variety of systems for analysis. Filtering of the sleep signal is contingent and should be implemented only when the required statistics remains cryptic
