Lessons from uncertainty on antifungal treatment in ICU

2017

We read with great interest the Editorial from Moghnieh et al. on the EMPIRICUS trial and antifungal use in intensive care unit (ICU) (1). Authors described nicely the trial and some background evidence on untargeted antifungal treatment in non-neutropenic critically ill patients in ICU (2,3). However, we believe that some points may be further clarified. First, it may be useful to cite the study from Knitsch et al. among those evaluating empiric antifungal treatment in ICU (4). Knitsch et al. enrolled 252 critically ill patients with localized/generalized intra-abdominal infection either of community or of nosocomial origin requiring emergency surgery.

Untargeted Antifungal Treatment Strategies for Invasive Candidiasis in Non-neutropenic Critically Ill Patients: Current Evidence and Insights

2017

Purpose of Review: The purpose of this study was to provide an overview and insights on important new concepts on untargeted antifungal treatment strategies, namely prophylaxis pre-emptive and empiric treatments for the management of invasive candidiasis (IC) in non-neutropenic critically ill patients. Recent Findings: Recently, clinical practice guidelines provided recommendation for the management of IC. However, results from recent trials and systematic reviews questioned the effect of untargeted antifungal treatment strategies, especially in terms of survival benefits in non-neutropenic patients, even with septic shock. Summary: Widespread use of untargeted antifungal treatment strategi…

Metabolite profile and in vitro activities of Phagnalon saxatile (L.) Cass. relevant to treatment of Alzheimer’s disease

2009

The present study describes for the first time the in vitro properties (inhibition of NO production and anticholinesterase) of Phagnalon saxatile (L.) Cass. (Asteraceae). The methanolic extract showed antioxidant activity that was measured by DPPH assay and beta-carotene bleaching test. The same extract inhibited NO production in the murine monocytic macrophage cell line RAW 264.7. Acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) inhibition was assessed by modifications of Ellman's method. Purification of the MeOH extract of P. saxatile allowed the isolation of phenolic compounds. Among them, the compounds that most effectively inhibited lipopolysaccharide-induced NO production …

Effects of a brief pre‑admission telephone reminder on no‑show and dropout rates in substance use disorder treatment: a quasi‑experimental study

2022

Abstract Background Appointment no-show and early dropout from treatment represent major challenges in outpatient substance use disorder treatment, adversely affecting clinical outcomes and health care productivity. In this quasi-experimental study, we examined how a brief reminder intervention for new patients before their first appointment affected treatment participation and retention. No-shows (not attending any sessions) and dropouts (discontinuation of initiated treatment because of three consecutively missed appointments) were compared between a period with pre-admission telephone calls (intervention) and a period without such reminders (non-intervention). Methods Participants were a…

CAUSE DI OLIGOANALGESIA IN AREA D’EMERGENZA AL TEMPO DELLE GRANDI IMMIGRAZIONI

2013

Obiettivo. L’AOU Policlinico di Palermo ha un centro dedi- cato ai bisogni sanitari degli immigrati regolari e clandestini, pertanto l’area di emergenza (PS) è il punto di riferimento di questa popolazione straniera. Il dolore, causa principale di accesso al PS, è sottotrattato. Le ipotesi delle differenze nella qualità del sollievo sono svariate, e comprendono anche etnia, razza, sesso ed età. Anche il modo in cui pazienti, di culture differenti, esprimono il proprio dolore e le interazioni tra medici e pazienti di diversa origine etnica possono influenza- re la valutazione. Abbiamo cercato di determinare se il sollie- vo dal dolore in PS è associato negativamente con la percezio- ne del m…

On the geographical distribution of pseudocholinesterase variants.

1975

The incidence of pseudocholinesterase (PCHE equals E.C. 3.1.1.8) variants in samples of 8 different population (total of 2218 individuals) is reported. Together with previously mentioned data from the literature, a general survey on the geographical distribution of PCHE isoenzymes is given. Possible reasons for present-day heterogeneity of their distribution are also discussed. Concerning the incidence of the C5 variant, it is pointed out that the validity of applying population genetic models depends upon the accuracy of the genetic basis.

Inhibition by oxotremorine of acetylcholine resting release from guinea pig-ileum longitudinal muscle strips

1975

1. Longitudinal muscle strips of the guinea-pig ileum were incubated in Tyrode solution containing either DFP or physostigmine as cholinesterase inhibior. After a 90 min preincubation period the acetylcholine resting release into the medium was determined. Acetylcholine was estimated by gas chromatography. 2. The resting release was 0.39 nmol/g×min irrespective of the cholinesterase inhibitor used. In the presence of hexamethonium, or after omission of external calcium, the resting release fell by 50 and 55%, respectively. 3. Oxotremorine (10−5 and 10−4 M) significantly inhibited the resting release of acetylcholine by 25 and 33%, respectively. The inhibitory effect of oxotremorine was comp…

Cholinesterase activity and exposure time to acetylcholine as factors influencing the muscarinic inhibition of [3H]-noradrenaline overflow from guine…

1985

Guinea-pig isolated atria were incubated and loaded with [3H]-noradrenaline. The release of 3H and of [3H]-noradrenaline was induced by field stimulation (6-9 trains of 150 pulses at 5 Hz). The stimulation-evoked overflows of 3H and of [3H]-noradrenaline were determined. In the absence of an inhibitor of acetylcholinesterase, acetylcholine (12 min preincubation before nerve stimulation, up to 10 microM) failed to inhibit the evoked [3H]-noradrenaline overflow. In the presence of atropine, an increase by acetylcholine of evoked release was observed in the same atria. In contrast, the selective muscarinic agonist methacholine significantly decreased the evoked overflow. The inhibition was ant…

Acetylcholine via Muscarinic Receptors Inhibits Histamine Release from Human Isolated Bronchi

1997

Human bronchi were incubated in organ baths to measure histamine release. The calcium ionophore A23187 (10 mumol/L; 1 min) stimulated histamine release by 148 +/- 28% (n = 11) above the prestimulation level but was ineffective in epithelium-denuded bronchi. Neither bradykinin (0.1 mumol/L) nor compound 48/80 (10 micrograms/ml) triggered the release of histamine from epithelium-intact bronchi. Acetylcholine did not affect spontaneous histamine release (about 2 nmol/g x 5 min) but inhibited A23187-evoked histamine release in an atropine-sensitive manner. Already a concentration as low as 0.1 nmol/L acetylcholine was effective, the maximal inhibition (by 89%) occurred at 100 nmol/L, whereas a …
