  • Hemorrhagic shock is a common cause of death in emergency rooms. Early diagnosis of hemorrhagic shock makes it possible for physicians to treat patients successfully. Therefore, the purpose of this study was to select an optimal survival prediction model using physiological parameters for the two analyzed periods: two and five minutes before and after the bleeding end. We obtained heart rates, mean arterial pressures, respiration rates and temperatures from 45 rats. These physiological parameters were used for the training and testing data sets of survival prediction models using an artificial neural network (ANN) and support vector machine (SVM). We applied a 5-fold cross validation method to avoid over-fitting and to select the optimal survival prediction model. In conclusion, SVM model showed slightly better accuracy than ANN model for survival prediction during the entire analysis period.

  • Purpose: The purpose of this study was to examine the effects of bed angles and bed rest time combined with hemostatic methods on discomfort and hemorrhagic complications in patients after transfemoral cerebral angiography. Methods: Data were collected from 93 inpatients following transfemoral cerebral angiography, from April 20 to September 23, 2016. Patients were grouped according to bed angle ($0^{\circ}$ vs. $30^{\circ}$) and bed rest time combined with hemostatic methods (4-hour bed rest after manual compression vs. 2-hour bed rest after applying vascular closure device). Results: There was a significant group differences on discomfort (F=46.44, p<.001). The post-hoc analysis showed the lowest score of discomfort in those with bed angle $30^{\circ}$ and 2-hour bed rest. There was no difference in hemorrhagic complications among 4 groups. Conclusion: The postangiograpy discomfort can be effectively reduced with the least hemorrhagic complications by bed angle $30^{\circ}$ elevation and 2-hour bed rest after applying vascular closure device for those underwent transfemoral cerebral angiography.

  • Mouse monoclonal antibodies (MAbs) were produced by using viral hemorrhagic septicemia virus (VHSV, genotype IVa) as an immunogen, isolated from diseased olive flounder (Paralichthys olivaceus). Four hybridoma clones secreting MAbs against VHSV were established. The MAbs were recognized the nucleoprotein (MAb 4), phosphoprotein (MAb 1) and matrix protein (MAbs 2 and 3) of VHSV by western blot analysis. Among them, the MAbs 1 and 4 strongly reacted with the VHSV-infected FHM cells, but not normal FHM cells. In enzyme linked immunosorbent assay, the four MAbs reacted with the VHSV, but not different six fish viruses (infectious hematopoietic necrosis virus, hirame rhabdovirus, spring viraemia of carp virus, infectious pancreatic necrosis virus, marine birnavirus and nervous necrosis virus). These results indicate that the MAbs are useful for diagnosis of VHSV infection.

  • Killed vaccines, developed by inactivation with formalin, have been investigated for many fish viruses. In this study, the inactivation of viral hemorrhagic septicemia virus (VHSV) by formalin was investigated based on the infectivity titer. When viral cell culture supernatants were used, the infectivity titer decreased 1,000-fold at 1 d after treatment with 0.1% (v/v) formalin, but was below the detection limit at 7 and 14 d. Moreover, neither the N nor G gene were detectable by RT-PCR immediately after formalin treatment. In western blot analysis, N protein was not detected by rabbit antiserum against VHSV KR-9225 from 2 d after formalin treatment. On the other hand, when we used a virus that was purified and concentrated ~100 times, the infectivity titer was maintained at 106.05 TCID50/mL, even at 14 d after formalin treatment, and no change in the viral structural proteins was observed. This study provides important data on the production and use of formalin-inactivated vaccines.

  • Non-occlusive mesenteric ischemia (NOMI) encompasses all forms of mesenteric ischemia with patent mesenteric arteries. NOMI is commonly caused by decreased cardiac output resulting in hypoperfusion of peripheral mesenteric arteries. We report a case of NOMI secondary to hemorrhagic shock and rhabdomyolysis due to trauma. A 42-year-old man presented to our trauma center following a pedestrian trauma. On arrival, he was drowsy and in a state of hemorrhagic shock. He was found to have multiple fractures, both lung contusion and urethral rupture. An initial physical examination and abdominal computed tomography (CT) scan revealed no evidence of intra-abdominal injury. High doses of catecholamine were administered for initial 3 days due to unstable vital sign. On day 25 of hospitalization, follow-up abdominal CT scan demonstrated that short segment of small bowel loop was dilated and bowel wall was not enhanced. During exploratory laparotomy, necrosis of the terminal ileum with intact mesentery was detected and ileocecectomy was performed. His postoperative course was uneventful and is under rehabilitation.

  • Two one-month-old dairy calves which have Eimeria oocysts in their bloody diarrhea died acutely a few days after showing the first clinical signs. At necropsy, hemorrhagic and congestive gastrointestinal organs were observed in both calves, and abomasal ulcerations existed. As a prevalent agent in all of the collected intra-intestinal specimens, Clostridium perfringens was isolated and the strain was identified as type A possessing alpha and beta2-toxins. In these clinical cases, intercurrent infection by C. perfringens type A and Eimeria through contaminated environment may be responsible for acute hemorrhagic enteritis.

  • Purposes: This study purposed to evaluate the effect of a value incentive program(VIP) on the in-hospital mortality of acute stroke. Methodology: Study period was from January 2010 to December 2018. This study included 63 hospitals for acute hemorrhagic stroke that the mortality rate per month was more than one during study period. Independent variables were time variables and hospital characteristics such as hospital type, district and bed number. Interrupted time series analysis was applied to analyze the data. Findings: In case of general hospitals, the in-hospital mortality rate per month for acute hemorrhagic stroke tends to be increased by 0.03% in overall study periods but decreased by 0.32% after the implementation of the policy. On the other hand, tertiary hospital changes are not statistically meaningful. Conclusion: This study provides evidences how the VIP was effective in improving quality of acute hemorrhagic stroke care. General hospitals showed higher policy effect compare to that of tertiary hospitals.

  • Lupus anticoagulant hypoprothrombinemia syndrome (LAHPS) is a rare entity characterized by the presence of lupus anticoagulant (LA) and prothrombin (factor II) deficiency. It may cause severe bleeding contrary to classical antiphospholipid syndrome. Here, we report a case of LAHPS presenting with a hemorrhagic ovarian cyst in a 17-year-old girl with systemic lupus erythematosus (SLE) nephritis. She had been followed up for 8 years. Her first manifestation of SLE was prolonged gingival bleeding after tooth extraction at 9 years of age. During the follow-up period, she had neither severe bleeding nor thrombotic complications despite a positive LA and a prolonged activated partial thromboplastin time (aPTT). At this visit, the patient presented with colicky abdominal pain, a hemorrhagic ovarian cyst, a prolonged prothrombin time, a prolonged aPTT, a low factor II level, and a positive LA, leading to the diagnosis of LAHPS. While a hemorrhagic ovarian cyst resolved completely in 3 months, she received oral pill, transfusions of red blood cells and plasma, and intravenous cyclophosphamide pulse therapy in combination with glucocorticoids due to persistent menorrhagia, anemia, prolonged aPTT, and lupus flaring. Thus, LAHPS needs to be considered in SLE patients with positive LA and prolonged aPTT.
