Purpose:?The aims of this study were to assess frequency of stress induced cardiomyopathy (SCMP) and predictors for incidence of SCMP in patients who admitted to medical ICU. We also explored the predictors of in-hospital mortality in patients with SCMP.?Method:?It is a retrospective cohort study. A total of 338 patients admitted to medical ICU and underwent transthoracic echocardiography (TTE) between January 2015 and December 2015 were enrolled. Definition of SCMP was defines as follows: 1) transient hypokinesis, akinesis of the left ventricular mid segments with or without apical involvement or the regional wall motion abnormalities extend beyond a single epicardial vascular distribution; 2) absence of obstructive coronary disease; 3) new EKG abnormalities or modest elevation in cardiac troponin; 4) absence of pheochromocytoma, myocarditis. Logistic regression model was used to analysis predictors for incidence of SCMP and predictors of in-hospital mortality in SCMP respectively. Cox regression model was used to analysis the influence of SCMP to mortality.?Results:?Of the 338 patients, SCMP was observed in 42 patients (12.4%). Compared to 296 patients without SCMP, patients with SCMP had lower frequency of DM (19% vs 29.2%, p=0.01), COPD (4.8% vs 16.9%, p=0.04) and higher prevalence of using mechanical ventilator (MV, 90.5% vs 71.9%, p=0.03), and lower ejection fraction (EF, 38.0±15.6 vs 61.7±11.8, p<0.001). In multivariate analysis, lower BMI (odd ratio, 0.88; 95% CI, 0.78 to 0.99; p=0.04) and lower EF (odd ratio, 0.90; 95% CI, 0.87 to 0.92; p<0.01) were associated with development of SCMP. In a Cox regression model adjusted with several confounders (age, DM, malignancy, liver cirrhosis, shock, acute kidney injury, use of MV) SCMP showed trend to increase of 60-day mortality (p=0.052). Among 42 patients with SCMP, acute kidney injury(AKI) was the only risk factor for predicting in-hospital mortality (odd ratio, 8.19; 95% CI, 1.35 to 47.75; p=0.02).?Conclusions:?Our study showed that prevalence of SCMP was 12.4% and trend to increase of 60-day mortality of critically ill patients. In patients with SCMP, AKI was the only risk factor for predicting in-hospital mortality.

U-healthcare는 종래의 헬스케어 영역에 유비쿼터스 기술을 접목하여 개인의 건강상태 관리를 도와주는 서비스이다. 이의 기반이 되는 기술인 질환 유무를 판별하는 기법은 그 동안 헬스케어 영역에 적용시켜 왔다. 하지만, 적시에 언제 어디서나 지속적인 모니터링이 요구되는 U-health환경에서는 기존의 기계학습기법을 그대로 적용하는 데에는 어려움이 있다. 본 논문에서는 통계기반의 질환 유무 판별 기법을 제안한다. 본 판별 기법은 질환 판별에 이용되는 생체신호와 신체증상의 종류로 배열 구조를 설정하고 축적된 데이터로부터 생체신호와 신체증상간의 쌍에 누적 빈도 수를 기록하여 학습한 뒤 고안한 판별식을 적용시켜 사용자의 질환을 판별하는 기법이다. 제한적인 검증이지만 약 360명의 실제 환자 데이터를 이용하여 기법을 검증하였고, 빠른 속도와 지속적인 개선이 가능한 기법임을 알 수 있었다. 추후 정확한 데이터를 기반으로 다른 기법과의 비교 검증으로 엄밀한 검증이 요구된다.

De Grouchy syndrome or Distal 18q- is a genetic condition caused by a deletion of genetic material within chromosome 18, and the deletion involves the distal section of 18q. It causes a wide range of medical and developmental concerns. Congenital orthopedic anomalies, cleft lip and palate are relatively common. People with distal 18q- are often small for their age. Most individuals with distal 18q- fall in the mild to moderate range of intellectual disability. Strabismus and nystagmus, changes in the optic nerve as well as colobomas are also fairly common. People with distal 18q- frequently have conductive and/or sensorineural hearing loss. At present, treatment for distal 18q- is only symptomatic. This article presents a case report: Caries treatment of a 4-year-old female patient with de Grouchy syndrome under general anesthesia. The special considerations of dental care, especially caries treatment for the patient with de Grouchy syndrome are discussed.
