Published: November 2019

El desarrollo tecnológico genera nuevas formas de producción, transmisión y recepción de información, es decir, han surgido nuevos contextos para los nuevos propósitos sociales (Cassany, 2008). En este sentido, en los documentos oficiales dentro del contexto educativo mexicano, uno de los objetivos principales es que cada estudiante desarrolle habilidades y competencias con el uso de las Tecnologías de Información y Comunicación (TIC), tomando en cuenta su nivel educativo y el equipamiento tecnológico (SEP, 2011). Con el objetivo de generar descripciones que muestren prácticas docentes con el uso de recursos digitales en un preescolar (cerca de la periferia de la ciudad de Xalapa, Veracruz) a través del proyecto Educación Mobile. Habilidades Digitales para una Educación de Calidad, coordinado por la Secretaría de Educación Pública (SEP), se realizó un estudio cualitativo con el uso de técnicas etnográficas para la recolección de la información, se hicieron observaciones en aula y entrevistas semiestructuradas, además se exploró la dinámica de operatividad del Proyecto Educación Mobile Veracruz.[1] Los resultados permiten reflexionar sobre las actividades que se desarrollan en el aula con las TIC, los objetivos curriculares, el posicionamiento de las docentes frente al uso de las TIC, la participación de los niños, y la dinámica de roles.

The Ubiquitous Imprint of Radiative Acceleration in the Mean Absorption Spectrum of Quasar Outflows
Authors: Mas-Ribas Lluís , Mauland Renate 
Published: December 2019

Abstract
Observational evidence revealing the main mechanisms that accelerate quasar outflows has proven difficult to obtain due to the complexity of the absorption features that this gas produces in the spectra of the emission sources. We build 36 composite outflow spectra, covering a large range of outflow and quasar parameters, by stacking broad

absorption line systems in the spectra of SDSS-III/BOSS DR12 quasars. The two lines of the atomic doublet of C iv, with a separation of ≈497 km s−1, as well as those of other species, appear well resolved in most of our composites. This agrees with broad outflow troughs consisting of the superposition of narrow absorbers. We also report on the ubiquitous detection of the radiative-acceleration signature known as line-locking in all our composite outflow spectra, including one spectrum that was strictly built from broad absorption line (BAL) systems. This is the first line-locking detection in BAL composite spectra. Line-locking is driven by the C iv atomic doublet and is visible on the blue side of most strong absorption transitions. Similar effects from the doublets of O vi, Si iv, or N v, however, seem to not be present. Our results confirm that radiation pressure is a prevalent mechanism for accelerating outflows in quasars.

Abstract
We report on eight millisecond pulsars (MSPs) in binary systems discovered with the Arecibo L-Band Feed Array (PALFA) pulsar survey. Phase-coherent timing solutions derived from 2.5–5 yr of observations carried out at the Arecibo and Jodrell Bank observatories are provided. PSR J1921+1929 is a 2.65 ms pulsar in a 39.6 day orbit for which we detect γ-ray pulsations in archival Fermi data. PSR J1928+1245 is a very low-mass-function system with an orbital period of 3.3 hr that belongs to the non-eclipsing black widow population. We also present PSR J1932+1756, the longest-orbital-period (41.5 days) intermediate-mass binary pulsar known to date. In light of the numerous discoveries of binary MSPs over the past years, we characterize the Galactic distribution of known MSP binaries in terms of binary class. Our results support and strengthen previous claims that the scatter in the Galactic scale height distribution correlates inversely with the binary mass function. We provide evidence of observational biases against detecting the most recycled pulsars near the Galactic plane, which overestimates the scale height of lighter systems. A possible bimodality in the mass function of MSPs with massive white dwarfs is also reported.

Published: December 2019

Abstract
One of the central goals of the Laser Interferometer Space Antenna (LISA) is the detection of gravitational waves from the merger of supermassive black holes. Contrary to stellar-mass black hole mergers, such events are expected to be rich X-ray sources due to the accretion of material from the circumbinary disks onto the black holes. The orbital dynamics before merger is also expected to modulate the resulting X-ray emission via Doppler boosting in a quasiperiodic way and in a simple phase relation with the gravitational wave from the inspiral of the black holes. Detecting the X-ray source would enable a precise and early localization of the binary, thus allowing many telescopes to observe the very moment of the merger. Although identifying the correct X-ray source in the relatively large LISA sky localization will be challenging due to the presence of many confounding point sources, the quasiperiodic modulation may aid in the identification. We explore the practical feasibility of such idea. We simulate populations of merging supermassive black holes, their detection with LISA, and their X-ray light curves using a simple model. Taking the parameters of the X-ray telescope on the proposed NASA Transient Astrophysics Probe, we then design and simulate an observation campaign that searches for the modulated X-ray source while LISA is still observing the inspiral of the black holes. Assuming a fiducial LISA detection rate of 10 mergers per year at redshift closer than 3.5, we expect a few detections of modulated X-ray counterparts over the nominal duration of the LISA mission.

Published: December 2019

Introduction: Worldwide urban pigeons (Columba livia domestica) are an important reservoir of pathogenic and multidrug-resistant bacteria (MDR). Plasmids are key genetic elements in the dissemination of antimicrobial drug resistance in bacteria, including beta-lactams and quinolones, which are the most important classes of drugs for treatment of Enterobacteriaceae infections in human and veterinary medicine. The aim of this study was to determine the presence of Escherichia coli (E. coli) harboring plasmids containing extend-spectrum (ESBL) and pAmpC beta-lactamases, also plasmid-mediated quinolone resistance (PMQR) genes in urban pigeons from São Paulo State, Brazil.
Methodology: A collection of 107 isolates of E. coli from urban pigeons from four cities was screened by antimicrobial resistance phenotypic and PCR for genes encoding ESBL, pAmpC and PMQR genes. Clonality was evaluated by ERIC-PCR.
Results: We found three strains positive for blaCTX-M genes. In two clonally related CTX-M-8-producing strains, the gene was associated with IncI1 plasmids. An MDR strain harboring blaCTX-M-2, the plasmid could not be transferred. No strain was positive for PMQR genes.
Conclusion: These results indicate that CTX-M-2 and CTX-M-8-producing E. coli are present in urban pigeons, which could serve as a reservoir for ESBL-producing E. coli in Brazil.

Published: December 2019

Introduction: This research aimed to determine the association of the combination of H. pylori infection and TP53 codon 72 polymorphism with non-cardia gastric cancer (GC) in Vietnam.
Methodology: A total of 164 patients with non-cardia GC and 164 patients with peptic ulcer disease or functional dyspepsia in controls matched by sex and age were enrolled. H. pylori infection was diagnosed by rapid urease test and polymerase chain reaction (PCR). The cagA gene-positivity and vacA sm subtypes were determined by multiplex PCR. Genotypes of TP53 codon 72 polymorphism were determined by PCR-restriction fragment length polymorphism.
Results: The prevalence of H. pylori infection in GC and control group were 61.6% and 55.4%, respectively. The rates of cagA-positive strains in the two H. pylori-positive groups were 80.2% and 71.4%, respectively. There was no statistically significant difference in TP53 codon 72 genotype distribution between GC group (frequencies of Arg/Arg, Arg/Pro and Pro/Pro genotypes were 31.1%, 43.3% and 25.6%, respectively) and controls (29.3%, 52.4% and 18.3%, respectively), p = 0.172. The significant difference in genotype distribution was observed in recessive model (Pro/Pro vs Arg/Arg + Arg/Pro) when stratifying by H. pylori infection (OR = 2.02, 95% CI 1.03–3.96, p = 0.041) and by cagA-positivity (OR = 2.33, 95% CI 1.07–5.07, p = 0.032).
Conclusions: This study suggests a synergistic interaction between H. pylori infection, especially cagA-positive H. pylori, and Pro/Pro genotype of TP53 codon 72 polymorphism might play a significant role in the pathogenesis of GC in the Vietnamese population.

Published: December 2019

Background: Cardiac device-related endocarditis has emerged as a serious complication in the era of advanced medical technology. Pacemaker related infections are rare and life-threatening with incidence from 0.06% to 7% and high mortality rate (30-35%). Diagnosis is hard, frequently delayed and could be even missed due to poor clinical findings. The average delay in diagnosis is 5.5 month. We report a case of the late-onset of pacemaker lead endocarditis caused by S. epidermidis successfully treated with open heart surgery.
Case Report: Patient with persistent high fever for 11 month and suspicion for infective endocarditis was admitted in Cardiovascular Institute. No clinical signs of endocarditis were observed. TTE revealed large vegetation 30 × 17 mm attached to the atrial electrodes with high embolic potential. This finding was verified by transesophageal echocardiography (TEE), although CT scan did not reveal vegetation. Blood cultures were negative. A sternotomy with cardiopulmonary bypass was performed and electrodes were extracted with large vegetation. Intraoperative finding revealed large thrombus with vegetation around pacemaker leads. Cultures of the electrodes and vegetation revealed Staphylococcus epidermidis. Surgery was followed up with antibiotic treatment for 6 weeks. He has been followed up for the next 2 years, and without complications.
Conclusion: The absence of criteria for endocarditis and negative blood cultures should not keep the physician from ruling out lead endocarditis. This complication carries high risk of mortality if left untreated.

Published: December 2019

Background:
Newly graduated nurses' communication ability often does not satisfy the needs of clinical sites. New training pedagogies are needed to help nursing students improve communication skills. This study aimed to evaluate the effects of simulation-based deliberate practice on cultivating nursing students' communication, empathy, and self-efficacy.

Method:
The study was a randomized controlled trial. A total of 132 first-year nursing students participated in the study at a nursing school in China. The intervention was guided by simulation-based education and deliberate practice. The Clinical Communication Ability Scale, Jefferson Scale of Empathy-Health Professionals, and General Self-Efficacy Scale were used to measure the students' outcomes.

Results:
After the intervention, students' scores of clinical communication ability, empathy, and self-efficacy in the experimental group all increased significantly, compared with those of the control group.

Conclusion:

The simulation-based deliberate practice program is a feasible teaching method targeting improvement in nursing students' communication, empathy, and self-efficacy.

Identification des Villages à Risque (IVR) : pour un état des lieux de la Trypanosomiase Humaine Africaine au Niger
Authors: Rouamba Jérémi , Salissou Adamou , Sakandé Hassane , Jamonneau Vincent , Courtin Fabrice 
Published: December 2019

Au Niger, la Trypanosomiase Humaine Africaine (THA) était sous contrôle dès les années 1950 et le dernier cas de THA autochtone connu dans la littérature a été dépisté en 1972. En 2013, l’OMS a affiché sa volonté d’éliminer la THA comme problème de santé publique à l’horizon 2020, il était donc impératif d’actualiser la situation de la THA au Niger. Cependant, en l’absence de données épidémiologiques récentes, où faut-il diriger les équipes médicales ? La méthode d’Identification des Villages à Risque (IVR) de THA permet d’établir, sur la base de critères liés à l’historique de la maladie et aux conditions géographiques actuelles, une liste de villages à risque. Ces derniers sont ensuite visités par une équipe légère qui récolte des informations épidémiologiques, géographiques et entomologiques, qui sont ensuite structurées dans une base de données géo-référencée qui est interrogée. Les villages les plus susceptibles d’héberger un cas de THA sont alors proposés pour une prospection médicale. En 2015, 28peuplements identifiés comme à risque ont été visités par une équipe légère, et sur les 384 Tests de Diagnostic Rapide (TDR) effectués, 12 se sont révélés positifs mais aucun n’a répondu positivement au test spécifique de la trypanolyse, écartant le diagnostic de la THA. Le Sud du Niger héberge encore quelques forêts-galeries bien conservées qui constituent des gîtes favorables aux glossines, exposant les populations riveraines à leur piqûre. Onze villages ont finalement été proposés pour une prospection médicale. Le contact homme/glossine doit être restreint à une population très spécifique, qui mène des activités à l’intérieur ou en périphérie du parc national du W. La situation de la THA au Niger doit être clarifiée pour permettre de mettre en place les stratégies de lutte adaptée en vue de son élimination.

Published: December 2019

IntroductionWorse survival in upper tract urothelial carcinoma (UTUC) in the presence of a tumour in the ureter vs. pelvicalyceal tumours is reported in some studies; however, the definition of ureteral involvement (UI) varies across studies. We systematically evaluated evidence regarding the prognostic role of UI in overall and cancer-specific survival of patients with UTUC.Material and methodsA systematic search of PubMed, Scopus and Web of Knowledge was performed in March 2018.ResultsThe results were presented as a comparison between ureteral vs. pelvicalyceal tumours. A total of 14,895 patients were identified. Cumulative analyses indicated that UI worsens cancer-specific survival (CSS) and overall survival (OS), with a pooled HR of 1.52 (p < 0.001) and 1.39 (p = 0.004), respectively.ConclusionOur meta-analysis identified UI in UTUC as an adverse prognostic factor.
