Cardiovascular Risk Assessment in a Cohort of Newly Diagnosed Patients with Obstructive Sleep Apnea Syndrome.

OBJECTIVES: Obstructive sleep apnea syndrome (OSAS) is associated with increased cardiovascular morbidity and mortality. The aim of this study was to assess whether the 10-year risk for cardiovascular disease in newly diagnosed patients with OSAS is increased. MATERIALS AND METHODS: Recently diagnosed, with polysomnography, consecutive OSAS patients were included. The Systematic Coronary Risk Evaluation (SCORE) and the Framingham Risk Score (FRS) were used to estimate the 10-year risk for cardiovascular disease. RESULTS: Totally, 393 individuals (73.3% males), scheduled to undergo a polysomnographic study with symptoms indicative of OSAS, were enrolled. According to apnea-hypopnea index (AHI), subjects were divided in four groups: mild OSAS (AHI 5-14.9/h) was diagnosed in 91 patients (23.2%), moderate OSAS (AHI 15-29.9/h) in 58 patients (14.8%), severe OSAS (AHI > 30/h) in 167 patients (42.5%), while 77 individuals (19.6%) had an AHI < 5/h and served as controls. Increased severity of OSAS was associated with increased SCORE (p < 0.001) and FRS values (p < 0.001). More specifically, a significant correlation was observed both between AHI and SCORE (r=0.251, p < 0.001) and AHI and FRS values (r=0.291, p < 0.001). Furthermore, a negative correlation was observed between FRS values and sleep efficiency (r=-0.224, p=0.006). CONCLUSIONS: The 10-year risk for cardiovascular morbidity and mortality seems to increase with severity of OSAS. Physicians should bear this finding in mind, in order to seek for and consecutively eliminate risk factors for cardiovascular disease and to prevent future cardiovascular events in OSAS patients.

The use of theatre in medical education in the emergency cases school: an appealing and widely accessible way of learning.

INTRODUCTION: Theatre models in medical education have been used worldwide in order to train medical students and graduates in managing various situations. However, the literature reports little regarding its appeal to trainees. We conducted a medical seminar, entitled Emergency Cases School, which employed such techniques. Actors simulated the actions of doctors and patients involved in various emergency cases, in front of a large audience, in a specially modified theatre hall which resembled the emergency room environment. METHODS: A total of 303 undergraduate medical students participated in the seminar. The audience evaluated the course with the DREEM questionnaire, along with two extra questions: Q1. 'Do you think that the course will prove itself beneficial to your clinical skills?' and Q2. 'Would you suggest the course to another student?', in a 0-4 scoring scale. Of the attendees, 281 (92.7%) answered the questionnaire. RESULTS: The overall DREEM score was 140.32 (±23.39) out of 150, which is interpreted as 'More positive than negative'. The results of Q1 and Q2 were 3.07 (±0.78) and 3.65 (±0.61), respectively. DISCUSSION: The Emergency Cases School received positive feedback as a theatre educational tool, targeted to a large audience. With the advantage of the realistic setting of an emergency room, along with its low-budget needs, this course model could function as a creative alternative of the more traditional lecturing teaching techniques.
