비알코올 지방췌장질환은 최근 관심 받고 있는 질환 중 하나로 비만 및 대사증후군과 연관된 췌장 지방축적으로 정의된다. 진단은 주로 영상학적 검사로 이루어지나 아직까지 명확한 표준 검사법은 확립되어 있지 않은 상태이다. 임상적 결과로써 대사증후군, 2형 당뇨병, 췌장 외분비 기능 부전, 급성 췌장염, 췌장 누공, 췌장암 및 비알코올 지방간질환 등과의 연관성이 보고되고 있다. 치료는 비알코올성 지방간질환과 비슷하게 식이요법과 체중 감량 및 운동을 통하여 췌장 지방축적을 최소화하는 전략이 도움이 될 수 있다. Nonalcoholic fatty pancreas disease (NAFPD) is a condition characterized by the accumulation of excess fat in the pancreas, commonly occurring in individuals with obesity. The diagnostic evaluation of NAFPD is mostly composed of image tests, but it is still less standardized. NAFPD is closely linked to metabolic syndrome, type 2 diabetes, pancreatic exocrine insufficiency, acute pancreatitis, pancreatic fistula, pancreatic cancer, and nonalcoholic fatty liver disease (NAFLD). However, further research is needed to investigate the mechanisms underlying these relevant clinical consequences. In terms of treatment, strategies aimed at minimizing pancreatic fat accumulation through dietary modifications and regular exercise, similar to the management of NAFLD, may be beneficial.

This paper describes parallel processing approach for structural optimization on transputer system which is loosely coupled MIMD computer with the local memory. The validity and efficiency of this approach are demonstrated and verified by some test models of trusses. Repeated structural analysis algorithms, which spend a lot of overall structural optimization processes, are based on substructuring scheme with domain-wise parallelism and converted to be adapted to hardware architecture. The initial problem data are modularized and assigned to each node in order to minimize the communication cost. The communications between nodes are limited to static condensation and behavior data collection.

Background/Aims: Acute-on-chronic liver failure (ACLF) is a widely recognized concept in which acute decompensation (AD) in patients with cirrhosis results in organ failure and high short-term mortality. On the other hand, few studies reflecting the various etiologies of cirrhosis are available. This study examined the clinical features of patients with hepatitis C virus (HCV)-related ACLF. Methods: Between January 2005 and December 2018, 109 HCV-related cirrhosis patients hospitalized for AD (ascites, hepatic encephalopathy, gastrointestinal hemorrhage, and bacterial infection) were enrolled for ACLF defined by the European Association for the Study of the Liver (EASL). Results: ACLF developed in 35 patients (32.1%) on admission. Eight, eight, and 19 patients had ACLF grades 1, 2, and 3, respectively. The 28-day and 90-day mortality rates were very low (2.7% and 5.4%, respectively) in patients without ACLF and very high (60.0% and 74.3%, respectively) in those with ACLF. In patients with HCV-related ACLF, compared to previous studies on hepatitis B virus-related ACLF and alcohol-related ACLF, the prevalence of liver failure was very low (17.1%), whereas that of kidney failure was very high (71.4%). Compared with all other prognostic scores, the Chronic liver failure Consortium Organ Failure score predicted the 90-day mortality most accurately, with an area under the receiver operator characteristic of 0.921. Conclusions: HCV-related ACLF has unique clinical characteristics distinct from hepatitis B virus-related and alcohol-related ACLF. ACLF defined by EASL can be useful for predicting the short-term mortality in HCV-related cirrhosis.
