Cognitive Behavioral Therapy and Trazodone Effects on Sleep and Blood Pressure in Insomnia

Insomnia · Insomnia Chronic · Insomnia, Primary

Individuals who have insomnia with short sleep duration (ISS) differ from individuals who have insomnia with normal sleep duration (INS) in terms of health risks (i.e., hypertension) and treatment response. This study will examine whether patients with ISS and INS demonstrate a differential response to two common insomnia treatments. One is behavioral, Cognitive Behavioral Therapy for Insomnia (CBT-I). The other is a widely prescribed, non-habit-forming medication, trazodone used at a low dose. The investigators' findings could lead to evidence-based treatment guidelines that help clinicians more effectively match treatments to insomnia patients and reduce associated health problems.

Comparative Efficacy of BRT and CBT-I for Insomnia

Insomnia Disorders · Insomnia Disorder · Insomnia

This study evaluates two behavioral treatments for patients with insomnia disorder: Bedtime Restriction Therapy (BRT) and Cognitive Behavioral Therapy for Insomnia (CBT-I). Both therapies aim to improve the clinical symptomatology of insomnia by teaching participants techniques to better manage their sleep schedule and habits. BRT is a simpler and shorter therapy focused on aligning the time spent in bed with reported sleep time. CBT-I includes additional components such as relaxation techniques and cognitive exercises. The study will compare these treatments to see if BRT is as effective as CBT-I in improving the clinical symptomatology of insomnia.

Laryngomalacia, Examinations and Quality of Life in Children Before and After Treatment With Follow-up After 1 Year

Laryngomalacia · Sleep Apnea, Obstructive · Sleep Apnea

Laryngomalacia is the most frequent cause of stridor in children under 1 year. The airway obstruction generates turbulent airway flow and creates the characteristic high-frequency stridor sound. In addition, the airway obstruction can cause apnea, a following drop in oxygen saturation and sleep disturbances. The symptoms of laryngomalacia are often worsened by activity, feeding, crying and lying flat on the back. The diagnosis is made with flexible laryngoscopy when the child is awake. The children are most often treated with expectation, information and guidance, observation with help with feeding and reflux treatment. Up to 20% of patients have a severe degree of laryngomalacia with apneas, which is an indication for surgical treatment. The investigators want to examine whether sleep examinations can help us deciding which child benefit from surgery, and follow-up the child again after 4-6 weeks and 1 year. The sleep examinations are carried out with polygraphy and/or polysomnography with simultaneous audio records and video monitoring and with Somnofy from VitalThings. The investigators want to use artificial intelligence and machine learning when analyzing the sleep examinations. The investigators also want to have a control group examining the sleep and breathing during night at home. In both groups the investigators want to examine the quality of life with the questionnaire ITQoL-SF47.

Treatment Failure of Continuous Positive Airway Pressure (CPAP) in Patients With Obstructive Sleep Apnea Syndrome (OSA): A Trial Comparing Polysomnography and the Sunrise Device to Drive Treatment-Adjustment Decisions.

Sleep Apnea Syndrome, Obstructive

The goal of this clinical trial is to determine whether treatment-adjustment decisions based on one night of home monitoring with the Sunrise device are comparable to decisions based on one night of in-laboratory polysomnography (PSG) in adults with obstructive sleep apnea (OSA) who remain insufficiently controlled with continuous positive airway pressure (CPAP) therapy. The main questions it aims to answer are: * Do Sunrise-based assessments lead to similar therapeutic decisions as PSG-based assessments? * Are residual apnea-hypopnea indices measured by Sunrise comparable to those measured by PSG? Participants will complete both assessment sequences in a randomized cross-over design. They will: * Use the Sunrise device for several nights with and without CPAP. * Undergo one night of PSG with and without CPAP. * Have their CPAP therapy reviewed based on the results of each assessment method.

Sleep Disordered Breathing With Opioid Use

Sleep Apnea · Opioid Use · Sleep Disordered Breathing

There is an increased risk for sleep disordered breathing (SDB), sleep-related hypoventilation and irregular breathing in individuals on chronic prescription opioid medications. Almost 30% of a veteran sleep clinic population had opioid-associated central sleep apnea (CSA). The proposal aims to identity whether oxygen and acetazolamide can be effective in reducing unstable breathing and eliminating sleep apnea in chronic opioid use via different mechanisms. We will study additional clinical parameters like quality of life, sleep and pain in patients with and without opioid use. This proposal will enhance the investigators' understanding of the pathways that contribute to the development of sleep apnea with opioid use. The investigators expect that the results obtained from this study will positively impact the health of Veterans by identifying new treatment modalities for sleep apnea.

Polysomnographic Findings in Nasal Polyposis

Chronic Rhinosinusitis With Nasal Polyps · Obstructive Sleep Apnea

Nasal polyposis (NP) is a chronic inflammatory disease of the nasal and sinus mucosa leading to protrusion of edematous polyps in the nasal cavity. Prevalence of NP among the chronic rhinosinusitis patients is 25-30 %. NP leads to significant limitations in physical, emotional and social aspects of life of the affected patients. Sleep disorder is frequently reported by those patients with impaired nasal breathing. Till now few studies have objectively assessed the impact of NP on sleep quality. the objectives are to figure out sleep disturbances in NP and to analyze the outcomes of sinus surgery on sleep recovering.

Disrupted Sleep and Concurrent Ectopy or Atrial Fibrillation

Obstructive Sleep Apnea · Premature Ventricular Contraction (PVC) · Atrial Fibrillation (AF)

Whereas the available evidence mostly supports chronic sleep disruption as a risk factor for incident AF, less is known about the near-term risk of a discrete atrial fibrillation (AF) episode following a night of disrupted or poor-quality sleep. This prospective, randomized, case-crossover study aims to examine the acute effects of sleep disruption on clinically relevant cardiac ectopy pertinent to AF.

Assessing the Effects of Cool Roofs on Indoor Environments and Health

Resting Heart Rate · Blood Glucose Control · Depression

Ambient air temperatures in Asian, Latin American, African, and Pacific climate hotspots have broken record highs in 2024, driven by man-made climate change. Solutions are needed to reduce heat exposure in communities. Sunlight-reflecting cool roof coatings passively reduce indoor temperatures and energy use to protect home occupants from extreme heat. Occupants living in poor housing conditions globally - for example in informal settlements, slums, and low-socioeconomic households - are especially vulnerable to increased indoor heat exposure. Heat exposure can instigate and worsen numerous physical, mental and social health conditions. The worst adverse health effects are being experienced in communities least able to adapt to heat exposure. By reducing indoor temperatures, cool roof use can promote physical, mental and social wellbeing in occupants. The long-term research goal is to identify viable passive housing adaptation technologies with proven health and environmental benefits to reduce the burden of heat stress in communities affected by heat globally. To meet this goal, the investigators will conduct a cluster-randomized controlled trial to establish the effects of cool roof use on health, indoor environment and economic outcomes in five urban climate hotspots: Ouagadougou, Burkina Faso; Colima, Mexico; Ahmedabad, India; Niue; and Tavua, Fiji.

Long Term Oral Appliance Therapy Effectiveness for Obstructive Sleep Apnea Syndrome

Obstructive Sleep Apnea

Obstructive sleep apnea (OSA) is a highly prevalent breathing problem that occurs during sleep. OSA have been associated with the obesity epidemic in developing countries; additionally, high OSA prevalence rates are present in populations with cardiovascular and metabolic disorders. Two OSA treatments are currently available, oral appliance (OA) therapy and continuous positive airway pressure (CPAP). OAs are an underutilized non-surgical treatment and few studies have analyzed their long-term effectiveness for patients with OSA. The purpose of this study is to assess the long-term effectiveness of OA therapy in patients with OSA and to explore any changes on cardiovascular related morbidity and mortality related to this therapy.

Clinical Characteristics of Sleep Disorders in Patients With Ulcerative Colitis

Colitis, Ulcerative · Sleep Quality · Gastrointestinal Microbiome

Ulcerative colitis(UC) is one of the two main forms of inflammatory bowel disease(IBD), which seriously affects the quality of life of patients. Previous studies have demonstrated that more than 60% of IBD patients have sleep disorders, which is emerging as an important risk factor for disease recurrence and poor prognosis. However, the mechanisms by which sleep disorders regulates the occurrence and development of IBD remain undefined. This study aims to explore the clinical characteristics of ulcerative colitis patients with sleep disorders based on the microbiota-gut-brain axis, to analyze the effects of sleep disorders on autonomic nervous function, gut microbiota, and metabolites in UC patients.
