ABSTRACT
BACKGROUND: Thromboelastography (TEG) has been used perioperatively during liver transplantation (LT) to provide a real-time global hemostasis assessment for targeted blood product replacement. We aimed to analyze the relationship between post-LT TEG results and outcomes. METHODS: We retrospectively analyzed patients undergoing LT from November 2008 to December 2014 at Mayo Clinic Florida. All 441 single-organ 1st-time LT patients aged ≥18 years requiring post-LT intensive care unit management were included. TEG parameters including r time, k time, α angle, and maximum amplitude were measured regularly during the first 24 hours after LT. Outcomes included return to the operating room secondary to bleeding, length of hospitalization, survival, and early allograft dysfunction. RESULTS: A prolonged and/or lengthening r time, k time, and r+k time were all independently associated with increased length of hospitalization after LT. Increased maximum amplitude on the first post-LT TEG was associated with early allograft dysfunction. No notable associations of TEG parameters with survival or return to operating room were observed. CONCLUSIONS: The association of absolute and temporal TEG value changes with increased length of hospitalization and early allograft dysfunction suggests that TEG may have a role in identifying patients at high risk for these outcomes.

BACKGROUND: Identifying inflammatory phenotypes is relevant in severe uncontrolled asthma. The aim of this study was to identify the different clinical, inflammatory, functional, and molecular phenotypes in patients with severe asthma and to investigate the potential role of sputum periostin as a biomarker of severe asthma phenotypes. PATIENTS AND METHODS: Sputum induction was performed in 62 patients diagnosed with severe asthma. Skin prick testing, lung function tests, exhaled nitric oxide, hematimetry, and total serum IgE were performed. Periostin was measured in sputum supernatants. RESULTS: Patients with asthma were phenotyped and 80% had late-onset asthma, 50% had fixed airflow obstruction, and 66% showed a Th2-high phenotype. With respect to inflammatory phenotypes, 71% were eosinophilic and 25% mixed granulocytic. Periostin levels were higher in patients with fixed as compared to variable airflow limitation (69.76 vs 43.84 pg/ml, P < 0.05) and in patients with eosinophilic as compared to mixed granulocytic phenotype (61.58 vs 37.31 pg/ml, P < 0.05). There was an inverse correlation between postbronchodilator FEV1 /FVC and periostin levels (-0.276, P < 0.05). CONCLUSION: This study demonstrates the utility of periostin in phenotyping severe asthma. Periostin levels in sputum are associated with persistent airflow limitation in asthma patients with airway eosinophilia despite treatment with high-dose inhaled corticosteroids.

Select liver transplantation (LT) recipients in our program are transferred from operating room to postanesthesia care unit for recovery and extubation with transfer to the ward, completely eliminating an intensive care unit (ICU) stay. Developing a reliable method to determine patients suitable for fast-tracking would be of practical benefit to centers considering this practice. The aim of this study was to create a fast-tracking probability score that could be used to predict successful assignment of care location after LT. Recipient, donor and operative characteristics were assessed for independent association with successful fast-tracking to create a probability score. Of the 1296 LT recipients who met inclusion criteria, 704 (54.3%) were successfully fast-tracked and 592 (45.7%) were directly admitted to the ICU after LT. Based on nine readily available variables at the time of LT, we created a scoring system that classified patients according to the likelihood of being successfully fast-tracked to the surgical ward, with an area under the curve (AUC) of 0.790 (95% CI: 0.765-0.816). This score was validated in an independent group of 372 LT with similar AUC. We describe a score that can be used to predict successful fast-tracking immediately after LT using readily available clinical variables.

The embryonic development of Cuban gar (Atractosteus tristoechus) was described under controlled laboratory conditions. During the whole embryogenesis seven periods were defined: the zygote (0-½ h), cleavage (¾-4 h), blastula (5-10 h), gastrula (12-20 h), segmentation (24-40 h), pharyngula (48-66 h) and hatching (72-96 h) periods. The stages were based on morphological features, generally readily identified by examination of the embryo with the dissecting stereomicroscope. Hatching occurred 96 ± 4 h after spawning at 28°C.
