Central Venous Catheter Adverse Events Are not Associated with Crowding Indicators.

Objective: Crowding in the emergency department (ED) impacts a number of important quality and safety metrics. We studied ED crowding measures associated with adverse events (AE) resulting from central venous catheters (CVC) inserted in the ED, as well as the relationship between crowding and the frequency of CVC insertions in an ED cohort admitted to the intensive care unit (ICU).

Methods: We conducted a retrospective observational study from 2008-2010 in an academic tertiary care center.

Aphrodisiac and spermatogenic potential of alkaloidal fraction of (Burm. f.) Bojer roots in male rats.

Roots of (Burm. f.) Bojer are used as aphrodisiac and spermatogenic in the treatment of male infertility.

Aphrodisiac and spermatogenic potential of alkaloidal fraction of Hygrophila spinosa T. Ander in rats.

Ethnopharmacological Relevance: Seeds of Hygrophila spinosa T. Ander (Acanthaceae) are traditionally used as aphrodisiac and spermatogenic in Indian System of medicine.

Aim Of The Study: Preliminary phytochemical screening of plant revealed the presence of alkaloids in seeds.

Z-score for benchmarking reader competence in a central ECG laboratory.

Background: ECGs from thorough QT studies must be read in a central laboratory by trained experts. Standards of expertise are not presently defined. We, therefore, studied the use of Z-scores to define reader competence.
