Obstructive sleep apnea syndrome is associated with significant cardiovascular morbidity and increased mortality. However, it was controversial whether obstructive sleep apnea syndrome could cause pulmonary hypertension. The controversy was resolved by several studies that have shown pulmonary hypertension in 20% to 40% of patients with obstructive sleep apnea syndrome without underlying other cardiopulmonary diseases and reductions in pulmonary arterial pressure in patients with obstructive sleep apnea syndrome after treatment with nocturnal continuous positive airway pressure. Recent studies provide strong evidence for endothelial dysfunction in obstructive sleep apnea syndrome and pulmonary hypertension. Endothelin-1 is a 21 amino acid peptide with diverse biologic activity such as highly potent vasoconstrictor and mitogen regulator that may play a key role in obstructive sleep apnea syndrome and pulmonary hypertension. Continuous positive airway pressure therapy is moderately effective in reducing pulmonary arterial pressure. Further researches are needed to assess the therapeutic efficacy of pharmacologic therapy with agents that inhibit the action of endothelin-1 in obstructive sleep apnea syndrome patients with pulmonary hypertension.

PURPOSE: This study was to examine the achievement rate of smoking cessation, to identify obstacles to smoking cessation, and to find means to achieve the goal of smoking cessation in college smokers. METHOD: This study was conducted from April 26th to September 13th 2004 and used a one-shot design. The subjects selected by convenient sampling were 29 college smokers who smoked over one cigarette a day, had a positive level of urine cotinine, participated in smoking cessation education 3 times. Thereafter, individual interaction was processed between the researcher and the subject using an interaction instrument. Data were analyzed based on frequencies.,percentages and means using SPSS/Win 10.0. RESULTS: The achievement rate of smoking cessation was 20.7% (6 students). The biggest obstacles smoking cessation were smoking stimuli (29 students) and lack of control (25 students). Among detailed obstacles, the biggest one was smoking at regular times, which was followed by withdrawal symptoms, smoking on drinking, and company with other smokers. The most effective means of smoking cessation mentioned by the subjects were in order of avoiding drinking situations, taking deep breaths, and exercising. CONCLUSION: The results of this study, using King's theory, showed that individual interaction is effective in achieving smoking cessation. Therefore, it is suggested to make further study and broaden smoking cessation education for college smokers.

It has been controversial whether upper airway resistance syndrome (UARS) is a distinct syndrome or not since it was reported in 1993. The International Classification of Sleep Disorders classified UARS under obstructive sleep apnea syndrome (OSAS) in 2005. UARS can be diagnosed when the apnea-hypopnea index (AHI) is fewer than 5 events per hour, the simultaneously calculated respiratory disturbance index (RDI) is more than 5 events per hour due to abnormal non-apneic non-hypopneic respiratory events accompanying respiratory effort related arousals (RERAs), and oxygen saturation is greater than 92% at termination of an abnormal breathing event. Although esophageal pressure measurement remains the gold standard for detecting subtle breathing abnormality other than hypopnea and apnea, nasal pressure transducer has been most commonly used. RERAs include phase A2 of cyclical alternating patterns (CAPs) associated with EEG changes. Symptoms of OSAS can overlap with UARS, but chronic insomnia tends to be more common in UARS than in OSAS and clinical symptoms similar with functional somatic syndrome are also more common in UARS. In this journal, diagnostic and clinical differences between UARS and OSAS are reviewed.
