    Abstract A 58-year-old man was admitted to our institution with sudden onset of hypotension and acute ischemia of left lower extremity. Electrocardiography showed ST segment elevation in leads V1~V6 and a transthoracic echocardiogram revealed antero-septal wall hypokinesis. He was given a diagnosis of acute myocardial infarction caused by left main coronary artery compression due to acute aortic dissection by enhanced computed tomography. We implanted a stent in the left main coronary artery and performed right external iliac-left femoral arterial bypass under general anesthesia. We performed a conventional total arch replacement and frozen elephant trunk and mitral valve repair at day 16. His postoperative course was good. Implantation of a left main trunk stent is an effective strategy for Stanford type A acute aortic dissection with left main coronary arterial occlusion before surgical repair.

    Abstract Deer overabundance is a contributing factor in the degradation of plant communities and ecosystems worldwide. The management and conservation of the deer-affected ecosystems requires us to urgently grasp deer population trends and to identify the factors that affect them. In this study, we developed a Bayesian state-space model to estimate the population dynamics of sika deer (Cervus nippon) in a cool-temperate forest in Japan, where wolves (Canis lupus hodophilax) are extinct. The model was based on field data collected from block count surveys, road count surveys by vehicles, mortality surveys during the winter, and nuisance control for 12 years (2007-2018). We clarified the seasonal and annual fluctuation of the deer population. We found a peak of deer abundance (2010) over 12 years. In 2011 the estimated deer abundance decreased drastically and has remained at a low level then. The deer abundance gradually increased from April to December during 2013-2018. The seasonal fluctuation we detected could reflect the seasonal migration pattern of deer and the population recruitment through fawn births in early summer. In our model, snowfall accumulation, which can be a lethal factor for deer, may have slightly affected their mortality during the winter. Although we could not detect a direct effect of snow on population dynamics, snowfall decrease due to global warming may decelerate the winter migration of deer; subsequently, deer staying on-site may intensively forage evergreen perennial plants during the winter season. The nuisance control affected population dynamics. Even in wildlife protection areas and national parks where hunting is regulated, nuisance control could be effective in buffering the effect of deer browsing on forest ecosystems.
