These results suggest that intestinal viability could be prolonged after acute ischemia using oxygenated perfluorocarbons and this could be a promising pretreatment modality for a variety of mesenteric ischemic forms.

Serum HA should be explored as an early marker of atheromatosis and cardiovascular risk.

Background: Studies on the serum concentration of hyaluronic acid (HA) in newly diagnosed patients with acute myeloid leukemia (AML), B-acute lymphoblastic leukemia (B-ALL), and mantle-cell lymphoma (MCL) are scarce. In this study, we focused on investigating whether HA could serve as a possible prognostic marker in patients with AML, B-ALL, and MCL. Methods: The serum concentration of HA was measured in a total of 51 patients with newly diagnosed AML, B-ALL, and MCL. Venous blood was collected 1 day before the initiation of chemotherapy (D0), on day 16 of the first cycle of chemotherapy (D16), and on D30. Results: The serum HA concentration on D0 in patients with AML, B-ALL, and MCL was higher than in the control group. For all types of hematological malignancy, on D0, serum HA values of nonsurvivors were higher than in survivors. Moreover, patients in relapse had higher levels of serum HA than patients in remission. A strong positive correlation between serum HA and ferritin, β₂-microglobulin, and lactate dehydrogenase was found. Conclusion: Serum HA may serve as a possible prognostic marker for AML, B-ALL, and MCL patients, especially on D0. Prospective case-control studies on larger populations may provide further information.

<abstract><sec> <title>Objective</title> <p>The investigation of intentional behavior of hospital staff to care for COVID-19 patients and the study of the factors that influences it.</p> </sec><sec> <title>Method</title> <p>This is a cross-sectional study, of 261 physicians and nurses working in a COVID-19 reference hospital. Data were collected by an anonymous questionnaire including demographic and professional characteristics and a scale measuring behavioral intention based on the Theory of Planned Behavior of Ajzen. Statistical analysis was performed by SPSS 21.</p> </sec><sec> <title>Results</title> <p>Mean age of participants was 40.8 years old, while most of them were nurses (75.7%). Behavioral intention mean score was 18.2 (5–21), which shows high intention to care for COVID-19 patients. Bivariate analysis between independent variables showed that behavioral intention mean score was higher for those that had cared for COVID-19 patients and those that did not (19.0% vs. 16.7%, p &lt; 0.001). Multivariate linear regression analysis identified that increased subjective norms (the perceived social pressure to perform or not the behavior) score was associated with increased behavioral intention score (p &lt; 0.001). Also, participants that provided care for COVID-19 patients had higher behavioral intention score (p &lt; 0.001).</p> </sec><sec> <title>Conclusion</title> <p>Healthcare staff, that cared for COVID-19 patients had high behavioral intention to continue caring for them. This finding could be used to inform policies and training for staff that will be employed in COVID-19 units.</p> </sec></abstract>
