Social media and nurse education: an integrative reviewof the literature
Introduction. The exponential advance of social media has touched all areas of society, no exception for
the professional and personal lives of healthcare people. The issue to be considered is not whether or not
social media are being used, but how they are used. The line between proper and improper use, and even
abuse, of social media is a subtle one. Thus, the key issue is to be aware of the tool that is being used and
this should be supported with suitable training for healthcare professionals and, at an even earlier stage,
for students at healthcare training institutions during their studies.
Objective. To describe, through an integrative review of the literature, the use of social media by teachers
and students during teaching activity and practical training courses.
Materials and methods. An integrative review of the literature was conducted in October 2014. The literature
search was performed by consulting the main biomedical databases: PubMed, CINAHL and Embase.
Results. The literature search brought up a total of 854 citations. 804 abstracts were excluded as they were
not relevant. Of the remaining 50, 31 were excluded for not meeting the general criteria and, hence, only 19
articles were included. Two aspects emerged from the works selected: the use and potential of social media
in nursing education and the ethical and professional implications of their use.
Conclusions. The analysis of the literature reveals two areas for further investigation: evaluating the
level of moral awareness in nursing education with regards to the use of Web 2.0 communication tools
and implementing teaching methods to promote the construction and development of moral reasoning in
professionals

Communication with the public in the health-care system: a descriptive study of the use of social media in Local Health Authorities and public hospitals in Italy
Introduction. In 2010 the Italian Ministry of Health set out recommendations for the use of social technology and Web 2.0, inviting organisations within the Italian national health service (Servizio Sanitario Nazionale, SSN) to equip themselves with instruments. Objectives. 1. to ascertain how many local health authorities (Aziende Sanitarie Locali, ASL) and public hospitals have a presence on the most widely used social media websites in Italy: Facebook, Twitter and YouTube; 2. to find out how well the Facebook, Twitter and YouTube pages of ASLs and public hospitals are known among the general population; 3. to find out how ASLs and public hospitals engage with the general public on social media sites. Materials and methods. The websites of all ASLs and public hospitals across the country were visited to look for the icons of the social media sites under examination. The data considered were publicly available upon access. Results. A total of 245 websites were analysed. 7.34% ASLs and hospitals had social media accounts. 8 organisations had an account on all three of the social media sites considered in the study. Conclusions. The results show a low presence of ASLs and hospitals on social media. Other studies are needed in this field
Nonextensive statistical mechanics applied to protein folding problem: kinetics aspects
A reduced (stereo-chemical) model is employed to study kinetic aspects of globular protein folding process, by Monte Carlo simulation. Nonextensive statistical approach is used: transition probability p i j between configurations i → j is given by p i j =[1 +(1 - q)ΔGi j/kB T ]1/(1-q), where q is the nonextensive (Tsallis) parameter. The system model consists of a chain of 27 beads immerse in its solvent; the beads represent the sequence of amino acids along the chain by means of a 10-letter stereo-chemical alphabet; a syntax (rule) to design the amino acid sequence for any given 3D structure is embedded in the model. The study focuses mainly kinetic aspects of the folding problem related with the protein folding time, represented in this work by the concept of first passage time (FPT). Many distinct proteins, whose native structures are represented here by compact self avoiding (CSA) configurations, were employed in our analysis, although our results are presented exclusively for one representative protein, for which a rich statistics was achieved. Our results reveal that there is a specific combinations of value for the nonextensive parameter q and temperature T, which gives the smallest estimated folding characteristic time (t). Additionally, for q = 1.1, (t) stays almost invariable in the range 0.9 < T < 1.3, slightly oscillating about its average value <img border=0 width=32 height=32 src="../../../../../../../img/revistas/bjp/v39n2a/a16txt01.gif" align=absmiddle > or = 27 ±σ, where σ = 2 is the standard deviation. This behavior is explained by comparing the distribution of the folding times for the Boltzmann statistics (q → 1), with respect to the nonextensive statistics for q = 1.1, which shows that the effect of the nonextensive parameter q is to cut off the larger folding times present in the original (q → 1) distribution. The distribution of natural logarithm of the folding times for Boltzmann statistics is a triple peaked Gaussian, while, for q = 1.1 (Tsallis), it is a double peaked Gaussian, suggesting that a log-normal process with two characteristic times replaced the original process with three characteristic times. Finally we comment on the physical meaning of the present results, as well its significance in the near future works
Hospital Discharge: Results From an Italian Multicenter Prospective Study Using Blaylock Risk Assessment Screening Score
PURPOSE:To analyze the predictive validity and reliability of the Blaylock Risk Assessment Screening Score (BRASS) Index in a large group of patients.
METHODS: Prospective multicenter observational study was conducted in six Italian hospitals. Data were collected in three phases.
FINDINGS: Seven hundred eleven patients were recruited. The mean length of hospitalization for low-risk patients was significantly shorter than those in the medium and high-risk groups. Patients with a BRASS Index lower than 10, unlike those with a higher BRASS Index, were mainly discharged home.
CONCLUSIONS: Our results indicate that the BRASS Index is useful to identify patients at risk for prolonged hospitalization.
CLINICAL RELEVANCE: The use of a validated BRASS instrument can be useful to screen the patients, improving individual discharge planning
Multi-gene phylogeny and divergence estimations for Evaniidae (Hymenoptera)
Ensign wasps (Hymenoptera: Evaniidae) develop as predators of cockroach eggs (Blattodea), have a wide distribution and exhibit numerous interesting biological phenomena. The taxonomy of this lineage has been the subject of several recent, intensive efforts, but the lineage lacked a robust phylogeny. In this paper we present a new phylogeny, based on increased taxonomic sampling and data from six molecular markers (mitochondrial 16S and COI, and nuclear markers 28S, RPS23, CAD, and AM2), the latter used for the first time in phylogenetic reconstruction. Our intent is to provide a robust phylogeny that will stabilize and facilitate revision of the higher-level classification. We also show the continued utility of molecular motifs, especially the presence of an intron in the RPS23 fragments of certain taxa, to diagnose evaniid clades and assist with taxonomic classification. Furthermore, we estimate divergence times among evaniid lineages for the first time, using multiple fossil calibrations. Evaniidae radiated primarily in the Early Cretaceous (134.1–141.1 Mya), with and most extant genera diverging near the K-T boundary. The estimated phylogeny reveals a more robust topology than previous efforts, with the recovery of more monophyletic taxa and better higher-level resolution. The results facilitate a change in ensign wasp taxonomy, with Parevania, and Papatuka, syn. nov. becoming junior synonyms of Zeuxevania, and Acanthinevania, syn. nov. being designated as junior synonym of Szepligetella. We transfer 30 species to Zeuxevania, either reestablishing past combinations or as new combinations. We also transfer 20 species from Acanthinevania to Szepligetella as new combinations
A tritrophic interaction at the Brazilian triple frontier: new record of parasitism on Conocephalus saltator (Sausurre, 1859) (Orthoptera, Tettigoniidae)
ABSTRACT We report for the first time a tritrophic relationship (host-parasitoid-hyperparasitoid) among Conocephalus saltator (Sausurre, 1859) (Orthoptera, Tettigoniidae), Ormia cfr. crespoi Tavares, 1965 (Diptera, Tachinidae), and Perilampus sp. (Hymenoptera, Perilampidae). Specimens of C. saltator were collected at the Parque Nacional do Iguaçu (Foz do Iguaçu, Paraná, Brazil) and reared in the laboratory, in order to detect eventual parasitoids. We collected and reared 904 katydids, with 113 of them parasitized, producing 123 fly puparia, and 18 puparia that developed to adults of Ormia cfr. crespoi. We also recorded the emergence of four hyperparasitoid wasps, Perilampus sp., from the fly puparia
Bed rest duration and complications after transfemoral cardiac catheterization: a network meta-analysis
AIM: To assess the effects of bed rest duration on short-term complications following transfemoral catheterization. METHODS & RESULTS: A systematic search was carried out in MEDLINE, Embase, CINAHL, Cochrane Database of Systematic Reviews, Scopus, SciELO, and in five registries of grey literature. Randomized controlled trials and quasi-experimental studies comparing different duration of bed rest after transfemoral catheterization were included. Primary outcomes were hematoma and bleeding near the access site. Secondary outcomes were arteriovenous fistula, pseudoaneurysm, back pain, general patient discomfort and urinary discomfort. Study findings were summarized using a network meta-analysis (NMA).Twenty-eight studies and 9217 participants were included (mean age 60.4 years). In NMA, bed rest duration was not consistently associated with either primary outcome, and this was confirmed in sensitivity analyses. There was no evidence of associations with secondary outcomes, except for two effects related to back pain. A bed rest duration of 2-2.9 hours was associated with lower risk of back pain (RR 0.33, 95%CI 0.17-0.62), and a duration over 12 hours with greater risk of back pain (RR 1.94, 95%CI 1.16-3.24), when compared to the 4-5.9 hours interval. Post-hoc analysis revealed an increased risk of back pain per hour of bed rest (RR 1.08, 95%CI 1.04-1.11). CONCLUSIONS: A short bed rest was not associated with complications in patients undergoing transfemoral catheterization; the greater the duration of bed rest, the more likely patients were to experience back pain. Ambulation as early as 2 hours after transfemoral catheterization can be safely implemented. REGISTRATION: URL: https://www.crd.york.ac.uk/prospero. Identifier: PROSPERO CRD42014014222

New native host plant records for frugivorous flies (Diptera: Tephritidae, Lonchaeidae) in Northeastern Brazil
The fruit flies Anastrepha fraterculus (Wiedemann, 1830), Anastrepha sororcula Zucchi, 1979, Ceratitis capitata (Wiedemann, 1824) (Diptera: Tephritidae) and Neosilba pendula (Bezzi, 1989) (Diptera: Lonchaeidae) are recorded for the first time emerging from Campomanesia dichotoma (O.Berg) Mattos and Campomanesia ilhoensis Mattos (Myrtaceae), two native species occurring in fragments of Atlantic Forest over dunes, in the northernmost limit of this biome in the state of Rio Grande do Norte, Brazil. The flies emerged from fruit samples obtained at the conservation area at Parque Estadual Dunas do Natal. The parasitoids that emerged from the puparia were also recorded, with Aganaspis pelleranoi (Brèthes) being recorded for the first time for the state. These records are of importance for monitoring and further understanding of the cycles on alternative hosts especially where these species are considered agricultural pests.
