Filter by:Sleep apnea is a common and serious health problem in the Polish population. According to epidemiological data problem concerns about 7% of the adult population. The most common sleep disorder is obstructive sleep apnea (OSA). The consequence of episodes of airway obstruction and sleep fragmentation is an inefficient sleep, pathological daytime sleepiness, falling asleep involuntarily, awakening with feelings of shortness of breath or throttling. The direct consequences of sleep apnea are hypoxia, increased heart rate and increased blood pressure. Frequent complications of OSA are hypertension, stroke, cardiac arrhythmia, coronary artery disease and pulmonary hypertension. An additional problem in patients with sleep apnea is an increased incidence of bruxism. Bruxism is a common problem; reports of prevalence range from 8-31% in the general population. The most common symptoms of bruxism include: hypersensitive teeth, tooth wear, damage to dental restorations (e.g. crowns and fillings), damage to periodontal and oral mucosa, masticatory muscle pain and headaches. The etiology of bruxism is multifactorial and not fully understood. It can be caused by biologic, psychologic and exogenous factors. Arousals during the apnea episodes are considered to be a major cause of sleep bruxism in OSA patients. The relationship between OSA and sleep bruxism is still not clearly defined. Further research is needed to help explain the relationship between these two phenomena, which will enable further therapy in patients with coexisting OSA and sleep bruxism (SB).
The aims of this study are to (1) examine the medication use patterns of commonly prescribed hypnotics and the factors that were associated with the long-term and short-term use patterns among the elderly population in Taiwan; (2)investigate the associations of using hypnotics with the elderly patients' disease statuses, efficacy and safety, as well as its pharmacokinetic and pharmacogenetic characteristics;(3) determine the clinical, economic and humanistic outcomes of using hypnotics and the corresponding contributing factors for the elderly in Taiwan.
This study is a clinical trial in which 300 Police Officers who currently work midnight shifts in the participating police departments will be recruited to test the effectiveness of a new web-based program to address sleep and associated problems related to shift work, particularly night shift work. Recruitment letters will be sent to all officers currently working midnight shift, with the goal of recruiting 300 officers willing to participate in the study. The 300 participants will be randomly assigned to either the experimental group (receiving the web-based program) or the waitlist control group. Participants in the experimental group will be given access to the program site (COPing with Shift Work) and the mobile application (Sleep Tracker). Following completion of the field test, participants in the control condition (as well as all other interested officers) will have access to the web-based COPing with Shift Work program. All participants will be asked to complete a baseline questionnaire containing multiple measures of sleep, dietary practices, physical activity and job performance. Participants will be asked to complete the posttest approximately three months following initial access to the intervention. Primary and secondary outcome measures: The Primary outcome measures are "sleep quality" as measured by the Pittsburgh Sleep Quality Index (PSQI) and "sleepiness" as measured by the sleepiness subscale of the widely used Karolinska Sleep Questionnaire (KSQ). The investigators have adapted the sleep measures to apply to individuals who work nights and may sleep during the day. Secondary outcome measures include the Nutritional Patterns Scale, a 13-item modification of the Block Self-Administered Diet History Questionnaire assessing the nutritional value of the respondent's diet; Attitudes Toward a Healthy Diet, a 17-item scale, based on the Health Belief Model and developed and validated by Trenkner and associates assessing perceived benefits and barriers to eating a healthy diet; the Godin Leisure-Time Exercise Questionnaire, a brief 4-item query of usual leisure-time exercise habits; and work productivity measured with the Work Limitations Questionnaire (WLQ), developed and validated by Lerner and associates. It is expected that the program group participants will have significantly better outcomes than the control group at three months.
