Purpose: Clinical trials of procalcitonin (PCT)-based algorithms for antibacterial therapy have shown a reduction in antimicrobial use and improved survival. Translation of PCT algorithms to clinical settings has often been unsuccessful. We hypothesized that appropriate utilization of PCT could be improved by implementing an antimicrobial stewardship team (AST) approach to PCT testing.
Methods: We completed a pre-post intervention evaluation of adult patients admitted to the intensive care unit with a diagnosis of sepsis. The standard PCT algorithm period (SPAP) cohort included patients enrolled before dedicated AST involvement. During the AST-supported PCT algorithm period (ASPAP), the AST reviewed and provided feedback for all appropriate patients. The primary outcome was adherence to the PCT algorithm.
Results: Thirty-five and 57 patients were evaluated in the SPAP and ASPAP cohorts, respectively. There were no differences in demographics or infection site between the groups. Baseline PCT assessment was ordered in a larger proportion of patients in the ASPAP cohort (90% vs 57%; P = 0.0006). Follow-up PCT measurement was performed in more patients in the ASPAP cohort (76% vs 23%; P < 0.0001). Antibiotics were discontinued per algorithm in more patients in the ASPAP cohort (25/57 [44%] vs 2/35 [7%]; P < 0.0001). Patients in the ASPAP cohort experienced a shorter total duration of antibiotics (5 vs 7 days; P = 0.02), with no significant difference in length of stay or 30-day readmission or mortality between the cohorts.
Conclusion: A PCT algorithm successfully implemented by an AST was associated with a significant decrease in total antibiotic days with no differences in mortality or length of stay.

The plasma activity of nine aminopeptidases was monitored over a year in first-episode psychotic patients. We observed significant differences in aminopeptidase B (APB), aminopeptidase N (APN) and dipeptidyl peptidase IV (DPPIV), but not in puromycin-sensitive aminopeptidase (PSA), prolyl endopeptidase (PEP), cysteine aminopeptidase (Cys-AP), aspartate aminopeptidase (Asp-AP), glutamate aminopeptidase (Glu) or piroglutamate aminopeptidase (PGI) in these patients compared to controls, and also a progressive increase in plasma activity, correlated to changes in scores on clinical scales, Global Assessment of Functioning scale (GAF) and Hamilton Depression Rating Scale (HDRS), at 1 month of follow-up. At 1 month after diagnosis, the median score obtained by patients on the GAF was negatively associated with the plasma activity of APB and PEP measured at the beginning of the psychotic episode, indicating a role as a negative prognostic factor that can predict psychiatric symptomatology.

Parkinson's disease (PD) is an age-related neurodegenerative disease characterized by a progressive motor disorder, but frequently is accompanied by autonomic symptoms such as hypotension. Together with the decrease of dopamine, significant decreases in aminopeptidase activities have been reported in PD brains. However, up to date there are no studies about changes of aminopeptidase activities in plasma of PD patients.
