Prospective evaluation of the efficacy, safety, and optimal biomarker enrichment strategy for nangibotide, a TREM-1 inhibitor, in patients with septic shock (ASTONISH): a double-blind, randomised, controlled, phase 2b trial.

Background: Activation of the triggering receptor expressed on myeloid cells-1 (TREM-1) pathway is associated with septic shock outcomes. Data suggest that modulation of this pathway in patients with activated TREM-1 might improve survival. Soluble TREM-1 (sTREM-1), a potential mechanism-based biomarker, might facilitate enrichment of patient selection in clinical trials of nangibotide, a TREM-1 modulator.

8Cl-cAMP modifies the balance between PKAR1 and PKAR2 and modulates the cell cycle, growth and apoptosis in human adrenocortical H295R cells.

Various types of protein kinase A (PKA) alterations have been observed in adrenocortical tumours and Carney complex (CNC). PKA is a heterotetramer of two regulatory and two catalytic subunits. The R1A and R2B proteins are the most abundant regulatory subunits in endocrine tissues.

[Use of double J ureteral stent as an alternative to prevent ureteroileal anastomosis stricture in orthotopic bladder substitution].

Objective: The aim of the study was to compare ureteroileal anastomosis strictures rates in patients receiving either double J stent or open-ended ureteral stent, after bladder replacement for cancer.

Methods: Medical charts from 75 patients who underwent cystectomy and Z pouch bladder substitution for bladder cancer, between 2001 and 2005, were retrospectively reviewed. Ureteroileal anastomosis was direct, spatulated end-to-side fashioned in all patients.

Relationship between cytochrome 3A activity, inflammatory status and the risk of docetaxel-induced febrile neutropenia: a prospective study.

Background: We hypothesized that cancer-related inflammation might increase the risk of febrile neutropenia (FN) induced by docetaxel (DCX, Taxotere), by both affecting the exposure to DCX and the tissue sensitivity.

Patients And Methods: Advanced cancer patients with normal liver function, performance status (PS)<3, were included. Cytochrome P450 3A (CYP 3A) activity was estimated before the first cycle of DCX by a single determination of midazolam plasma concentration, 4 hours after 0.

Pharmacokinetics and toxicity of docetaxel: role of CYP3A, MDR1, and GST polymorphisms.

Objective: Patients initiating docetaxel chemotherapy were genotyped for CYP3A4, CYP3A5, MDR1, GSTM1, GSTT1, GSTM3, and GSTP1 to identify variability factors of docetaxel pharmacokinetics and toxicity.

Methods: Genotyping was performed by direct sequencing (CYP3A4), real-time polymerase chain reaction (CYP3A5), and polymerase chain reaction-restriction fragment length polymorphism (MDR1 and GST). The clearance and area under the curve of docetaxel were calculated by use of a Bayesian approach.

Feasibility of azithromycin prophylaxis during a pertussis outbreak among healthcare workers in a university hospital in Paris.

The objective of the present study was to evaluate the feasibility of azithromycin prophylaxis with respect to tolerability and compliance during a pertussis outbreak among healthcare workers in a university hospital ward. Compliance with the prophylaxis regimen was 89%; compliance was 75% from intent-to-treat perspective. The rate of adverse events was 33%.

In vitro and in vivo inhibitory effect of stiripentol on clobazam metabolism.

A metabolic interaction between stiripentol (STP), an anticonvulsant agent that inhibits the activity of several cytochromes P450 (P450s), and clobazam (CLB), a 1,5-benzodiazepine, used in association with STP in severe myoclonic epilepsy in infancy was observed in vivo. This interaction was characterized in vitro using cDNA-expressed CYP3A4 and CYP2C19 (main P450 involved in CLB metabolism) to calculate K(i) and IC(50) of stiripentol in comparison with ketoconazole (CYP3A4 inhibitor) and omeprazole (CYP2C19 inhibitor). STP inhibited N-demethylation of CLB to N-desmethylclobazam (NCLB) mediated by CYP3A4 (noncompetitively) and CYP2C19 (competitively) with K(i) = 1.

Effect of positioning on the incidence of abnormalities of muscle tone in low-risk, preterm infants.

Unlabelled: BACKGROUND. The preterm infant is subject to the force of gravity: when its body lies pressed against the mattress on which it is placed.

Aims: The purpose of this study was to investigate short-term effects of varied post-natal lying positions in order to prevent neuromuscular and postural abnormalities.

[The emergency department: a new concept for a reform].

Emergency care are now restructuring in France. The role of emergency departments is defined by new regulations. They include the closure of small emergency rooms and definition of three levels for the others.
