Psychosocial precursors of the correct sanitation and sanitization of the patient unit in the hospital setting.

Background And Aim Of The Work: Worrying data indicate the urgency of strongly limiting Healthcare-Associated Infections (HAI). Therefore, according to the Theory of Planned Behavior, the psychosocial precursors of correct sanitation and sanitization were assessed.

Methods: An Italian sample of hospital health workers (nurses, healthcare assistants, cleaners; N=250), replied to a validated questionnaire measuring: a) knowledge of HAI; b) favorable attitude towards the correct sanitation and sanitization procedure; c) perception that the management and colleagues give importance to the government of infectious risk; d) perception of being able to implement risk management behaviors; e) perception of having received proper training for the prevention of HAI.

Catheter-associated urinary tract infection: Role of the setting of catheter insertion.

Background: This study aimed to describe the epidemiology of catheter-associated urinary tract infections (CAUTIs) in patients admitted to a surgical ward in Central Italy and to analyze the associated risk factors.

Methods: An active surveillance program for CAUTI was carried out in patients catheterized for at least 48 hours. Place of catheter insertion (operating room, hospital ward, cystoscopy room, emergency care unit), indication for catheterization and its duration, among other risk factors were monitored until discharge.

Serum thyroid-stimulating hormone as a predictor of cognitive impairment in an elderly cohort.

Background: It is unclear whether in late life serum thyroid-stimulating hormone (TSH) predicts risk of developing cognitive impairment.

Objective: This study investigated the prospective relationship of serum TSH with the risk of developing mild cognitive impairment (MCI), Alzheimer's disease (AD) and vascular dementia (VaD) in an elderly cohort with a 4-year follow-up.

Methods: Data are for 660 subjects aged 65 years and older from an Italian population-based cohort who were cognitively normal at an extensive assessment in 1999/2000 and underwent follow-up assessment in 2003/2004.

2,5-Dimethyl-1H-pyrrole-3,4-dicarbaldehyde as a precolumn derivatization reagent for HPLC/UV detection of amino acids.

The use of 2,5-dimethyl-1H-pyrrole-3,4-dicarbaldehyde as a precolumn derivatization reagent for HPLC analysis of amino acids is proposed. The compound reacts under mild conditions (10min at ambient temperature) with primary amino groups. The derivatization conditions to obtain quantitative reaction were optimised by considering different parameters (temperature, pH and reagent concentration) using l-Val as the model compound.

Liquid chromatographic fluorescence determination of amino acids in plasma and urine after derivatization with phanquinone.

Phanquinone (4,7-phenanthroline-5,6-dione) has been investigated as a pre-column derivatization fluorogenic reagent for liquid chromatographic determination of primary amino acids in biological samples. The derivatization reaction was carried out at 68 degrees C both in the presence of aqueous phosphate buffer (pH 8) for 30 min and without buffer for 60 min to allow the determination of basic amino acids (Orn, Lys, Arg). The resulting derivatives were separated under reversed-phase HPLC and detected at lambda(em) = 460 nm with lambda(ex) = 400 nm.

Phanquinone as a suitable derivatization reagent in micellar electrokinetic chromatography and HPLC analysis of amino acids.

Phanquinone (chemically: 4,7-phenanthroline-5,6-dione) was applied as an original precolumn derivatization reagent for amino acids followed by separation using MEKC with UV detection (240 nm). The derivatization reaction was carried out at 68 degrees C in the presence of aqueous phosphate buffer (pH 8.0) and it was found to be complete after 30 min.
