Mapping the landscape of sleep medicine training across Asia.

STUDY OBJECTIVES: This study assessed the current state of sleep medicine accreditation and training in Asia by conducting a comprehensive survey across 29 Asian countries and regions facilitated by the Asian Society of Sleep Medicine to identify existing gaps and provide recommendations for future enhancements. METHODS: The Asian Society of Sleep Medicine Education Task Force Committee designed a survey to gather data on accreditation, education, and training standards in sleep medicine, including information on challenges in enhancing education in the field. RESULTS: With an 86% (25 countries/regions) response rate, the survey showed that sleep medicine is recognized as an independent specialty in just 9 countries/regions (36% of the countries/regions surveyed). Ten countries/regions have established sleep medicine training programs, with Japan and Saudi Arabia offering it as a distinct specialty. Significant disparities in training and accreditation standards were identified, with many countries/regions lacking formalized training and practice guidelines. The survey also revealed that most local sleep societies across Asia support the development of an Asian Sleep Medicine Training Curriculum led by the Asian Society of Sleep Medicine. However, several barriers significantly impede the establishment and development of sleep medicine training programs, including the scarcity of trained specialists and technologists and the absence of national accreditation for sleep medicine. CONCLUSIONS: The survey highlights the need for standardized sleep medicine training and accreditation across Asia. Developing an Asian Sleep Medicine Training Curriculum and promoting Asian Society of Sleep Medicine accreditation guidelines are key recommendations. Implementing these strategies is essential for advancing sleep medicine as a widely recognized discipline throughout Asia. CITATION: BaHammam AS, Al-Abri MA, Abd Rashid R, et al.

Increases in Heart Rate Variability Signal Improved Outcomes in Rapid Response Team Consultations: A Cohort Study.

BACKGROUND: Reduced heart rate variability (HRV) indicates dominance of the sympathetic system and a state of "physiologic stress." We postulated that, in patients with critical illness, increases in HRV might signal successful resuscitation and improved prognosis. METHODS: We carried out a prospective observational study of HRV on all patients referred to the rapid response team (RRT) and correlated with serial vital signs, lactate clearance, ICU admission, and mortality. RESULTS: Ninety-one patients were studied. Significantly higher HRV was observed in patients who achieved physiological stability and did not need ICU admission: ASDNN 19 versus 34.5, p=0.032; rMSSD 13.5 versus 25, p=0.046; mean VLF 9.4 versus 17, p=0.021; mean LF 5.8 versus 12.4, p=0.018; and mean HF 4.7 versus 10.5, p=0.017. ROC curves confirmed the change in very low frequencies at 2 hours as a strong predictor for ICU admission with an AUC of 0.772 (95% CI 0.633, 0.911, p=0.001) and a cutoff value of -0.65 associated with a sensitivity of 78.6% and a specificity of 61%. CONCLUSIONS: Reduced HRV, specifically VLF, appears closely related to greater severity of critical illness, identifies unsuccessful resuscitation, and can be used to identify consultations that need early ICU admission.

Pleomorphic rhabdomyosarcoma with pulmonary tumour embolism.

Pulmonary tumour embolism is a known complication of cancer disease. To date, pleomorphic rhabdomyosarcoma has been described once with this entity. We report a case of pulmonary tumour embolism diagnosed in the operation room after cardiac arrest of a 30-year-old male patient who had surgical amputation of his right upper limb due to recurrent sarcoma, mandating urgent and successful embolectomy.
