The main aims are:* To prospectively obtain demographic and clinical information of patients referred for a sleep study.* To determine the diagnostic value of facial discoloration as potential marker for obstructive sleep apnea to increase detection rate for the condition.* To establish a correlation between obstructive sleep apnea and vasovagal symptoms with resulting increased smoking tendency and study the effect of treatment on the disorders.* To determine the association between timing of appearance of obstructive sleep apnea symptoms and initiation of smoking., conditionsModule conditions: Obstructive Sleep Apnea, conditions: Vasovagal Syncope, conditions: Smoking, conditions: Acanthosis Nigricans, designModule studyType: OBSERVATIONAL, designInfo observationalModel: COHORT, timePerspective: PROSPECTIVE, enrollmentInfo count: 200, type: ESTIMATED, armsInterventionsModule interventions name: In-lab polysomnography, interventions name: Continuous positive airway pressure, outcomesModule primaryOutcomes measure: Clinical association between obstructive sleep apnea and presence of facial pigmentation, primaryOutcomes measure: Clinical association between obstructive sleep apnea and severity of facial pigmentation, primaryOutcomes measure: Relation between obstructive sleep apnea and vasovagal symptoms, primaryOutcomes measure: Relation between obstructive sleep apnea and resulting smoking tendency due to vasovagal symptoms, secondaryOutcomes measure: Relation between obstructive sleep apnea and the effect of treatment on facial discolouration, secondaryOutcomes measure: Relation between obstructive sleep apnea and the effect of treatment on vasovagal symptoms, secondaryOutcomes measure: Relation between obstructive sleep apnea and the effect of treatment on smoking habits, eligibilityModule sex: ALL, minimumAge: 18 Years, stdAges: ADULT, stdAges: OLDER_ADULT, contactsLocationsModule locations facility: The University of Jordan, status: RECRUITING, city: Amman, zip: 11942, country: Jordan, contacts name: Asma Btoosh, MD, role: CONTACT, phone: 00962797684137, email: asmaalbtoosh@gmail.com, contacts name: Rand M Zaqqa, role: PRINCIPAL_INVESTIGATOR, contacts name: Ayah M Zaqqa, MD, role: PRINCIPAL_INVESTIGATOR, contacts name: Maisa Mansoor, MD, role: PRINCIPAL_INVESTIGATOR, contacts name: Asma Btoosh, MD, role: PRINCIPAL_INVESTIGATOR, contacts name: Salah Salah, role: SUB_INVESTIGATOR, geoPoint lat: 31.95522, lon: 35.94503, documentSection largeDocumentModule largeDocs typeAbbrev: Prot, hasProtocol: True, hasSap: False, hasIcf: False, label: Study Protocol, date: 2024-03-07, uploadDate: 2024-03-07T14:03, filename: Prot_000.pdf, size: 82683, hasResults: False
