1. 6. Cardiovascular and respiratory effects of apnea in humans

   Författare :Johan Andersson; Funktionell zoologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; lung volume; breath-hold diving; Apnea; breath-holding; face immersion; cold stimulation; diving response; diving reflex; circulation; bradycardia; vasoconstriction; arterial blood pressure; cardiac output; spleen; respiration; splenic contraction; alveol; Physiology; Fysiologi; Respiratory system; Andningsorganen; Animal physiology; Djurfysiologi;

   Sammanfattning : This thesis deals with cardiovascular and respiratory effects of apneas in humans. During apnea (breath-holding), a number of interacting cardiovascular reflexes are initiated, and together these reflexes are called the “diving response”. LÄS MER

3. 7. Pediatric Obstructive Sleep Apnea : Evaluation of surgical treatments and immunological aspects

   Författare :Isabella Sjölander; Danielle Friberg; Johan Hellgren; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Obstructive sleep apnea; pediatric sleep disordered breathing; tonsillar surgery; Polysomnography; adenotonsillotomy; adenotonsillectomy; Strength and Difficulties Questionnaire; OSA-18; Oto-Rhino-Laryngology; Oto-rhino-laryngologi;

   Sammanfattning : Pediatric obstructive sleep apnea (OSA) is a sleep-related breathing disorder often caused by  enlargement of the adenoid and the tonsils. The peak prevalence is among children who are two to six years of age, when the lymphatic tissue is  most active. Clinical diagnosis can be challenging, since the symptoms are often unspecific.

4. 8. Snoring and Sleep Apnea in Women : Risk Factors, Signs and Consequences

   Författare :Malin Svensson; Eva Lindberg; Mats Holmström; Ludger Grote; Uppsala universitet; []
   Nyckelord :snoring; sleep apnea; women; general population; risk factors; daytime sleepiness; inflammation; pharynx;

   Sammanfattning : Obstructive sleep apnea syndrome (OSAS) is characterized by snoring, apneas and excessive daytime sleepiness (EDS). Obesity is a risk factor for snoring and sleep apnea, but data on other factors in relation to obesity are ambiguous. Symptoms of sleep apnea in women have not been fully elucidated. LÄS MER

5. 9. Cardiovascular dysfunction in obstructive sleep apnea

   Författare :Holger Kraiczi; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Obstructive sleep apnea; blood pressure; cardiac size; left ventricular function; endothelium-dependent vasodilation; forearm vascular conductance; natriuretic peptides;

   Sammanfattning : This thesis addresses relationships between the presence or severity of obstructive sleep apnea (OSA) and blood pressure (BP) as well as other signs of cardiovascular dysfunction.In a cross-sectional investigation of a sleep laboratory cohort of 81 patients, a dose response relationship was observed between the number of apneas plus hypopneas per hour of sleep (apnea-hypopnea index, AHI; measured with polysomnography) and office systolic and diastolic BP (SBP and DBP), daytime ambulatory DBP as well as nighttime ambulatory SBP and DBP (all ambulatory measurements taken at 20-minute intervals).

7. 10. Obstructive sleep apnea and cardiovascular morbidity

   Författare :Yüksel Peker; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Obstructive sleep apnea; cardiovascular; hypertension; coronary artery disease; hospitalization; cost utility; morbidity; mortality; secondary prevention; angiotensin II; CPAP;

   Sammanfattning : Obstructive sleep apnea (OSA) affects 24 % of middle-aged men and 9 % of women in USA but the treatment criterion, daytime sleepiness is reported by 17 and 22 % of these subjects, respectively. Some previous studies have suggested an association between OSA and cardiovascular disease (CVD), but the conclusions have been conflicting due to co-existing traditionally recognized risk factors.
