Hematocrit has no effect on peritoneal transport indices.

Published: February 1996

To assess the effect of hematocrit (Hct) on peritoneal transport indices (PTi), we studied the relationship between Hct (mean 28.1 +/- 5.1%, range 19.1-41.3%) and PTi with 118 peritoneal equilibration tests (PETs; 270 min, 1.36%) on 52 stable patients on peritoneal dialysis. Furthermore, considering a Hct 30% as ideal in peritoneal dialysis (PD), 14 patients who had performed a PET both with a Hct <30% and > or = 30% were checked for any variations in the PTi and blood pressure. We analyzed the subsequent PTi: ultrafiltration; creatinine (Cr) and blood urea nitrogen (BUN) clearance and mass transfer area coefficient (MTAC); 120, 240, and 270 min Cr D/P, UN D/P and glucose D/D0. Linear regressions between Hct and the PTi (118 PETs) did not prove statistically significant. The analysis of the PTi in 14 patients who had performed a PET with both a Hct < 30% and > or = 30% did not prove statistically significant, and no change in blood pressure was demonstrated. We do not consider Hct to have a significant influence on PTi.

Background: Allogeneic hematopoietic cell transplantation (allo-HCT) is a potential cure for many hematological malignancies. Historically, older adults were not considered eligible for allo-HCT due to increased toxicity and mortality concerns. This systematic review and meta-analysis aim to explore the outcomes of allo-HCT in patients aged 70 years or older.

This study involves the design, divergent synthesis, conformational and structural analysis, target prediction, and molecular docking simulations of novel nano N-thiazolylpyridylamines 2-7 and 10 as potential cyclin-dependent kinase 2 (CDK2) inhibitors. Using a divergent synthesis approach, the compounds were designed with structural variation and optimization in mind. The conformational and structural properties were explored through various spectroscopic techniques, confirming the structure, stability, and preferred conformations.

A series of multi-target organoselenides 3a-h has been synthesized with the advantages of a simple operation, and good yields of 66-89 % escorted by mechanistic enlightenment. The compounds 3b, 3c continued to exist as orthorhombic and trigonal, whereas 3d exist as monoclinic confirmed by the X-ray crystallography. Organoselenides 3c and 3f displayed the highest % radical scavenging potential with % inhibition of 98.

Background: In recent years, with the increase of antibiotic resistance, tigecycline has attracted much attention as a new broad-spectrum glycylcycline antibiotic. It is widely used in the treatment of complex skin and soft tissue infections, complex abdominal infections and hospital-acquired pneumonia by inhibiting bacterial protein synthesis. Tigecycline can exhibit significant time-dependent bactericidal activity, and its efficacy is closely related to pharmacokinetics.
