Background. Patients undergoing liver transplantation are in a state of coagulopathy before surgery because of liver failure. Intraoperative hemorrhage, massive transfusions, and post–reperfusion syndrome further contribute to coagulopathy, acidosis, and hypothermia. In such situations, temporary cessation of surgery with open abdominal management and resuscitation in the intensive care unit (ICU), which is commonly used as a damage control strategy in trauma care, may be effective. We assessed the outcomes of open abdominal management in liver transplantation and the corresponding complication rates. Methods. We retrospectively reviewed the outcomes of patients undergoing open abdominal management among 250 consecutive liver transplantation cases performed at our institution from 2009 to 2022. Results. Open abdominal management was indicated in 16 patients. The open abdomen management group had higher Model for End-stage Liver Disease scores (24 versus 16, P

Abstract Abnormal peripheral perfusion (PP) worsens the prognosis of patients with septic shock. Polymyxin B-direct hemoperfusion (PMX-DHP) increases blood pressure and reduces vasopressor doses. However, the modification of PP following administration of PMX-DHP in patients with vasopressor-dependent septic shock have not yet been elucidated. A retrospective exploratory observational study was conducted in patients with septic shock treated with PMX-DHP. Pulse-amplitude index (PAI), vasoactive inotropic score (VIS), and cumulative fluid balance data were extracted at PMX-DHP initiation (T0) and after 24 (T24) and 48 (T48) h. Changes in these data were analyzed in all patients and two subgroups (abnormal PP [PAI

Abstract Background The required fluid volume differs among patients with septic shock. Enterocyte injury caused by shock may increase the need for fluid by triggering a systematic inflammatory response or an ischemia-reperfusion injury in the presence of intestinal ischemia/necrosis. This study aimed to evaluate the association between enterocyte injury and positive fluid balance in patients with septic shock. Methods This study was a post hoc exploratory analysis of a prospective observational study that assessed the association between serum intestinal fatty acid-binding protein, a biomarker of enterocyte injury, and mortality in patients with septic shock. Intestinal fatty acid-binding protein levels were recorded on intensive care unit admission, and fluid balance was monitored from intensive care unit admission to Day 7. The association between intestinal fatty acid-binding protein levels at admission and the infusion balance during the early period after intensive care unit admission was evaluated. Multiple linear regression analysis, with adjustments for severity score and renal function, was performed. Results Overall, data of 57 patients were analyzed. Logarithmically transformed intestinal fatty acid-binding protein levels were significantly associated with cumulative fluid balance per body weight at 24 and 72 h post-intensive care unit admission both before (Pearson’s r = 0.490 [95% confidence interval: 0.263–0.666]; P

Abstract Septic shock is characterized by dysregulated vascular permeability. We hypothesized that the vascular permeability of endothelial cells (ECs) would be regulated by serotonin via serotonin-Rho-associated kinase (ROCK) signaling. We aimed to determine the impact of 5-hydroxyindoleacetic acid (5-HIAA) on septic shock as a novel biomarker. Plasma 5-HIAA levels and disease severity indices were obtained from 47 patients with sepsis. The association between 5-HIAA levels and severity indices was analyzed. Permeability upon serotonin stimulation was determined using human pulmonary microvascular ECs. 5-HIAA were significantly higher in septic shock patients than in patients without shock or healthy controls (p = 0.004). These elevated levels were correlated with severity indexes (SOFA score [p

The 5-year survival rate for pancreatic cancer has improved (10%) but remains worse than that for other cancers. Early pancreatic cancer diagnosis is challenging, and delayed diagnosis can delay treatment, which impairs survival. Practitioners do not promptly refer cases to a general hospital, causing delayed discovery. Herein, we aimed to examine the usefulness of the Pancreatic Cancer Project in Matsue, whose objective is to detect pancreatic cancer in patients presenting at any medical institution in Matsue City. Clinical data were extracted from medical records, and abdominal ultrasonography and tumor marker blood level assessments were performed (n = 234; median age, 71 [range, 41–94] years; 51% male). Cases with abnormal abdominal ultrasonography or blood test findings were referred for specialist imaging and followed up. The pancreatic cancer detection rate was 6.0% (n = 14); all cases were referred to a general hospital by practitioners within 1 month. Patients had stage IA (n = 1), IIA (n = 6), IIB (n = 2), III (n = 1), and IV (n = 4) disease. Overall, pancreatic cancer could be detected at an earlier stage (I–II), but referral to a general hospital by visiting practitioners should be prompt. The Pancreatic Cancer Project in Matsue may help improve the detection and prognosis of pancreatic cancer.

Objective: To characterize the pre- and postoperative coagulation profiles of patients undergoing adult-to-adult living donor liver transplantation (LDLT), using various coagulation tests and rotational thromboelastometry (ROTEM). Methods: This single-center observational study evaluated the various coagulation profiles of 22 patients (13 men and 9 women). Blood samples were obtained immediately after the induction of anesthesia (PRE) and on postoperative days (PODs) 1, 3, 5, and 7 after LDLT surgery. Results: Most procoagulant factors (fibrinogen, platelet, and coagulation factors II, VII, VIII, and IX) improved to levels equal to or greater than the PRE levels on POD 7. The levels of von Willebrand factor significantly increased after surgery, whereas those of disintegrin-like and metalloproteinase with thrombospondin type 1 motif 13 decreased. Although the thrombin-antithrombin III complex increased immediately after surgery, the plasmin-α 2 plasmin inhibitor complex increased only on POD 7. The level of plasminogen activator inhibitor-1 increased on POD 1, returning to PRE levels on POD 3. Almost all ROTEM parameters were decreased or prolonged, compared to the PRE levels, on POD 7. Conclusions: The values of most coagulation tests showed the improvement or acceleration of coagulability on POD 7 than at PRE, with almost all the ROTEM parameters decreased or prolonged. Therefore, it cannot be concluded whether ROTEM reflects the net effect of hemostatic balance after liver transplantation.
