Is it cost effective to use a 2% chlorhexidine wipes bath to reduce central-line associated blood stream infection? A quasi-experimental study.

Background: Bathing with 2% chlorhexidine (CHG) wipes is an important measure regarding infection prevention in critically ill patients. The aim of this study was to evaluate the impact of CHG wipes bath to prevent central-line associated bloodstream infection (CLABSI) in critically ill patients and determine if such measure is cost-saving.

Methods: a quasi-experimental study, conducted from July 2017 to April 2019.

Controlling Legionella pneumophila in water systems at reduced hot water temperatures with copper and silver ionization.

Background: Hospital-acquired Legionnaires' disease is associated with the presence of Legionella pneumophila in hospital water systems. In the United Kingdom, the Department of Health recommends maintaining hot water temperatures >55°C and cold water temperatures <20°C at the point of delivery to prevent proliferation of L pneumophila in water systems. In this study, we evaluated the efficacy of copper and silver ionization to control L pneumophila at deliberately reduced hot water temperatures (43°C) within a newly installed water system in a new building linked to a large health care facility in the United Kingdom.

Oral bioaccessibility of toxic and essential elements in raw and cooked commercial seafood species available in European markets.

The oral bioaccessibility of several essential and toxic elements was investigated in raw and cooked commercially available seafood species from European markets. Bioaccessibility varied between seafood species and elements. Methylmercury bioaccessibility varied between 10 (octopus) and 60% (monkfish).

Polycyclic aromatic hydrocarbons bioaccessibility in seafood: Culinary practices effects on dietary exposure.

This work aimed to determine the effect of culinary practices on the contamination level and bioaccessibility of polycyclic aromatic hydrocarbons (PAHs) in seafood. The selected farmed seafood species (marine shrimp, clams and seaweed) were commercially available in Portugal. The mean concentrations of PAHs varied between 0.

Macro and trace elements in Paracentrotus lividus gonads from South West Atlantic areas.

Sea urchin represents one of the most valuable seafood product being harvested and explored for their edible part, the gonads or roe. This species is generally considered a sentinel organism for ecotoxicological studies being widely used in monitoring programs to assess coastal aquatic environments quality, because is directly exposed to anthropogenic contaminants in their habitat. In this context, the aim of this study is to evaluate the concentrations of macro (Cl, K, P, Ca, S) and trace (Zn, Br, Fe, Sr, I, Se, Rb, Cu, Cr, Ni, As, iAs, Cd, Pb, Hg) elements in Paracentrotus lividus gonads from three South West Atlantic production areas subjected to distinct environmental and anthropogenic pressures.

Preliminary assessment on the bioaccessibility of contaminants of emerging concern in raw and cooked seafood.

A preliminary assessment of the bioaccessibility of contaminants of emerging concern (CeCs), including perfluorinated compounds (PFCs; i.e. PFOS and PFUnA), brominated flame retardants (BFRs; i.

Occurrence of halogenated flame retardants in commercial seafood species available in European markets.

PBDEs (congeners 28, 47, 99, 100, 153, 154, 183, 209), HBCD (α, β, γ), emerging brominated flame retardants (PBEB, HBB and DBDPE), dechloranes (Dec 602, 603, 604, syn- and anti-DP), TBBPA, 2,4,6-TBP and MeO-PBDEs (8 congeners) were analysed in commercial seafood samples from European countries. Levels were similar to literature and above the environmental quality standards (EQS) limit of the Directive 2013/39/EU for PBDEs. Contaminants were found in 90.

The influence of display modalities on proximal caries detection and treatment decision.

The aim of this study was to investigate the influence of digital radiographic display on caries detection and choice of treatment among undergraduate students. Forty images of extracted human teeth were acquired using a PSP digital system. The proximal surfaces were evaluated for the presence of proximal caries and choice of treatment by 36 undergraduate students, divided into three groups according to the semester they were taking.

Comparison of methods for the measurement of body composition in overweight and obese Brazilian children and adolescents before and after a lifestyle modification program.

Aim: To compare the body composition of overweight children and adolescents by bioelectrical impedance analysis (BIA) and dual-energy X-ray absorptiometry (DXA) before and after physical activity program.

Methods: One hundred and eleven patients with mean age (SD) of 12 (1.9) participated in the study.

Performance of activated sludge diffusion for biological treatment of hydrogen sulphide gas emissions.

Odours from wastewater treatment plants are comprised of a mixture of various gases with hydrogen sulphide (H(2)S) often being the dominant constituent. Activated sludge diffusion (ASD) as a biotreatment system for odour abatement has been conducted for over 30 years but has limited broad application due to disagreement in the literature regarding the effect that ASD may have on wastewater treatment performance. The effects of continuous H(2)S diffusion at 25 ppmv, with weekly peaks of approximately 100 ppmv, on H(2)S removal efficiency and wastewater treatment performance was evaluated over a 2-month period using an activated sludge pilot plant.

Nosocomial infections caused by Elizabethkingia meningoseptica: an emergent pathogen.

We hereby describe the clinical and epidemiological features and, outcomes of nine patients with Elizabethkingia meningoseptica infections in two hospitals over a 2-year period. All infections caused by this pathogen were nosocomial, or healthcare associated infections, in hemodialysis settings whereas none was correlated with hospital outbreaks.

Impact of prolonged low-grade physical training on the in vivo glucocorticoid sensitivity and on glucocorticoid receptor-alpha mRNA levels of obese adolescents.

Background/aim: Healthy individuals present variable responses of the hypothalamic-pituitary-adrenal (HPA) axis induced by different patterns of physical training. The aim of this study was to evaluate whether prolonged low-grade physical training influences the HPA axis and also glucocorticoid receptor-alpha (GRalpha) mRNA levels in mononuclear cells of obese adolescents.

Methods: We studied 19 patients with BMI above the 95th percentile (male:female ratio 7:12) aged from 9.

Maternal-infant bonding and the mother's participation during venipuncture: a psychoanalytic perspective.

Professionals discuss accompanying mothers' participation during painful procedures as a possibility of care to mother and child, but there is no consensus on this subject. To contribute to this topic, this study addresses the child's needs during venipuncture in a hospital environment and the mother's participation in this procedure, based on authors from psychoanalysis and mother-child bonding.

[Nursing physical examination of the full-term neonate: self-instructional software].

The purpose of this research is to elaborate software about the physical examination of full-term newborns (TNB) for neonatal nursing teaching at undergraduate level. The software was developed according to the phases of planning, content development and evaluation. The construction of the modules was based on Gagné's modern learning theory and structured on the Keller Plan, in line with the systemic approach.
