Satisfacción con la atención de enfermería en los consumidores de drogas: evolución de una escala

Objectives: To identify the degree of satisfaction with nursing care, the significant variables and contribute to the evolution of the scale.Methods: Descriptive, correlational, cross study, with 180 drug users. Data collected using the scale called “Satisfaction of users with the Nursing Health Center26”, between February and December 2012 in three treatment units in the region of Lisbon and Vale do Tejo, Portugal. Results: Users indicated 83.3% satisfaction. The dimension “Information individualization” was the most marked (98.5%). The more stability in the programs, abstinence from stimulants and benzodiazepines and more nursing interventions, the greater the satisfaction. Better working conditions, specializing in mental health, younger ages and less experience of nurses also contributed to satisfaction. Four items of the scale were extracted, assuming new SUCECS22 designation. Conclusions: Satisfaction was high, influenced by structural variables of users, nurses and working conditions. The scale has proved suitable for assessment in this population.info:eu-repo/semantics/publishedVersio

Photography-based taxonomy is inadequate, unnecessary, and potentially harmful for biological sciences

The question whether taxonomic descriptions naming new animal species without type specimen(s) deposited in collections should be accepted for publication by scientific journals and allowed by the Code has already been discussed in Zootaxa (Dubois & Nemésio 2007; Donegan 2008, 2009; Nemésio 2009a–b; Dubois 2009; Gentile & Snell 2009; Minelli 2009; Cianferoni & Bartolozzi 2016; Amorim et al. 2016). This question was again raised in a letter supported by 35 signatories published in the journal Nature (Pape et al. 2016) on 15 September 2016. On 25 September 2016, the following rebuttal (strictly limited to 300 words as per the editorial rules of Nature) was submitted to Nature, which on 18 October 2016 refused to publish it. As we think this problem is a very important one for zoological taxonomy, this text is published here exactly as submitted to Nature, followed by the list of the 493 taxonomists and collection-based researchers who signed it in the short time span from 20 September to 6 October 2016

Biophysical and flavonoid-binding studies of the G protein ectodomain of group A human respiratory syncytial virus

The human Respiratory Syncytial Virus (hRSV) is the major causative agent of lower respiratory tract diseases in infants, young children and elderly. The membrane protein G is embedded in the viral lipid envelope and plays an adhesion function of the virus to host cells. The present study reports the production of the group A hRSV recombinant G protein ectodomain (edG) and its characterization of secondary structure and thermal unfolding by circular dichroism (CD), as well as the binding investigation of flavonoids quercetin and morin to this protein by fluorescent quenching. CD data reveal that edG is composed mostly of β-structure and its melting temperature is of 325 K. Fluorescence quenching experiments of hRSV edG show that the dissociation constants for the flavonoids binding are micromolar and the binding affinity for the edG/quercetin complex is inversely dependent on rising temperature while is directly dependent for the edG/morin interaction. The thermodynamic parameters suggest that hydrophobic contacts are important for the edG/morin association while van der Waals forces and hydrogen bonds contribute to the stabilization of the edG/quercetin complex. Thus, data reported herein may contribute to the development of new treatment strategies that prevent the viral infection by hRSV
