Published: April 2023

ObjectiveTo explore the safety and efficacy of the combination of continuous intravenous infusion of esketamine with sacral block for postoperative analgesia in pediatric patients undergoing surgery for hypospadiasMethodsPediatric patients (n = 77) undergoing surgery for hypospadias were randomized into two groups: a hydromorphone group (H group, initial dose, 0.02 mg/kg; maintenance dose, 0.01 mg/kg/h) or an esketamine group (E group, initial dose, 0.3 mg/kg; maintenance dose 0.15 mg/kg/h). Caudal epidural block involved injection of 0.2% ropivacaine 1 ml/kg through the sacral hiatus. Age, weight, grade of hypospadias, intraoperative blood loss, operative time, and awaking time of patients were recorded. The Face, Legs, Activity, Cry and Consolability (FLACC) scale and Ramsay sedation scores were recorded when leaving the PACU (0 h) and at postoperative 2, 6, 12, 24, 36, and 48 h. The Pediatric Anesthesia Emergence Delirium Scale (PAED), incidence of hypotension, respiratory depression, nausea and vomiting and pruritus, and the time to first bowel movement after surgery were recorded.ResultsThere were no significant differences in demographic and clinical characteristics between the H group and the E group. There were no significant differences in FLACC scores at postoperative 0, 2, 6, 12, 24, 36, and 48 h in intra-group and inter-group comparisons. There were no significant differences in Ramsay sedation scores at postoperative 0, 2, 6, 12, 24, 36, and 48 h in the intra-group comparisons. Ramsay sedation scores were significantly lower at postoperative 2, 12, and 36 h in the H group compared to the E group. There were no significant differences in the PAED scale or incidence of nausea and vomiting or pruritus between the H group and the E group. The incidence of hypotension and respiratory depression was significantly lower, and the time to first bowel movement was significantly shorter in the E group compared to the H group. Urinary tryptophan, 5-hydroxytryptamine and substance P levels were significantly lower but arginine was significantly higher in the E group compared to the H group.ConclusionsThe combination of continuous intravenous infusion of esketamine with sacral block provided safe and effective postoperative analgesia for pediatric patients undergoing surgery for hypospadias.Trial registrationChinese Clinical Trial Register ChiCTR2200066967.

Published: April 2023

In this paper, first, the meso-debonding process of a GAP/CL20/AP composite solid propellant under uniaxial tension was analyzed using the advantages of the material point method (MPM) and the finite element method (FEM) for the first time; then, the numerical simulation results were compared with the experiments. Based on the basic principle of modeling with the material point method, grains of different sizes were generated quickly and efficiently. Next, the grains were dispersed into particles, and the position information of the particles was mapped onto the background grid, so the background grids were used to determine the position of the grains. After that, the generated AP and CL20 grains were imported into the commercial software Abaqus through python scripting codes for numerical calculation. Based on macro-mechanical tests and a micro-numerical simulation, this paper studies the micro-internal mechanism that affects the macro-mechanical properties of composite solid propellants. Three interface parameters needed to be determined by parameter inversion, and the value of the objective interpolation function minR was 0.05078%. From a comparison, it was found that the numerical simulation results are in good agreement with the experimental results in the aspects of micro-crack cracking characteristics and the nominal stress–strain curve of propellants. After that, the influence of interface parameters on the stress–strain curve are discussed. The research in this paper has high scientific value and engineering application value and can provide important reference and guidance for the design of composite solid propellants and its mechanical property analyses, so as to solve the structural integrity problem of solid rocket motor charges.

Published: April 2023

This study reports on the absolute photoionization cross sections for the magnesium-like Cl5+ ion over the 190–370 eV photon energy range, corresponding to the L-shell (2s and 2p subshells) excitation regime. The experiments were performed using the Multi-Analysis Ion Apparatus (MAIA) on the PLéIADES beamline at the SOLEIL synchrotron radiation storage ring facility. Single and double ionization ion yields, produced by photoionization of the 2p subshell of the Cl5+ ion from the 2p63s2 1S0 ground state and the 2p63s3p 3P0,1,2 metastable levels, were observed, as well as 2s excitations. Theoretical calculations of the photoionization cross sections using the Multi-Configuration Dirac-Fock and R-matrix approaches were carried out, and the results were compared with the experimental data. The Cl5+ results were examined within the overall evolution of L-shell excitation for the early members of the Mg-like isoelectronic sequence (Mg, Al+, Si2+, S4+, Cl5+). Characteristic photon energies for P3+ were estimated by interpolation.

Published: April 2023

Trichomonas vaginalis causes trichomoniasis, the most recurrent sexually transmitted infection (STI) worldwide. Genital mycoplasmas, not considered STI agents, are frequently isolated from the female genital tract. A symbiosis between Mycoplasma species and T. vaginalis has been described. The aim of this study was to conduct molecular-based analyses of vaginal specimens, thus assessing the prevalence of non-STI Mycoplasma infections. In total, 582 samples from female patients and an additional 20 T. vaginalis isolates were analyzed by PCR using Mycoplasma specific 16S rRNA primers, and the obtained PCR products were sequenced. Mycoplasma species were detected in 28.2% of the collected vaginal samples. Mycoplasma hominis was found in 21.5% of the specimens, Ureaplasma species were found in 7.5% of the samples. The molecular data of the newly described species, CandidatusMycoplasma girerdii, were obtained for the first time in Austria, in a sample also positive for T. vaginalis. Analyses of the cultivated T. vaginalis strains confirmed the presence of M. hominis in two out of 20 samples. A comparably high prevalence of genital mycoplasmas was revealed through advanced diagnostic assays, with M. hominis and U. parvum being the most prevalent species. The previously described symbiotic relationship between M. hominis and T. vaginalis was confirmed.

Martine Fabbri, Las identificaciones femeninas en la bulimia : "una falta a tener, una falta a ser".
La bulimia, conducta mayoritariamente femenina y sobreviniente a la adolescencia, parece testimoniar de representaciones de la feminidad, que están unidas, en parte, a las expenencias más précoces, constitutivas del narcisismo. Una ilustración es propuesta en las pruebas proyectivas y en particular en el Rorschach, con la ayuda de un abanico de cuatro casos.

Elsa Schmid-Kitsikis, Puede una teoría psicoanalítica del pensamiento integrar los descubrimientos piagetianos ?
Entre los procesos que definen el pensamiento, existe uno que ocupa un lugar central, aquél que se refiere a la capacidad del individuo a pensar el pensamiento del otro a través de su propia capacidad a considerar su pensamiento como objeto interno susceptible de ser pensado. El análisis de las nociones piagetianas de esquema, de asimilación/acomodación y de auto-organización, respecto al acercamiento psicoanalítico del pensamiento, subraya su contribución a una teoria de la significación y del estatuto narcisístico de la actividad pensada.

Les représentations populaires du « mental »
Authors: Duruz Nicolas 
Published: April 2023

Nicolas Duruz, Las representaciones populares de lo "mental".
En esta investigación, el autor pone en evidencia una tipología de las representaciones populares de "la actividad mental". Sobre la base de 60 entrevistas conducidas acerca de una población no "psi", interpretados según un análisis de contenido comprensivo y no cuantitativo, el autor clasinca las representaciones en función de dos dimensiones : la intensidad de la actividad mental (dinámica vs estática) y su polaridad referencial (independencia vs dependencia de la realidad externa). Este estudio reposa sobre el postulado que el profesional "psi", tanto por razones éticas que de eficadidad, debe tener en cuenta en su trabajo con sus clientes a con sus pacientes de las "teorías subjetivas" de las cuales estos disponen para representar y explicar su problema. En función de esta tipología, cuatro perfiles de clientes tipo son esbozados con el fin de ayudar el profesional a ajustar mejor sus estrategias de intervención.

Les enfants battus : un dévoilement difficile
Authors: Selosse Jacques 
Published: April 2023

Après quelques romanciers du 19ème siècle, ce sont les médecins légistes en France et les pédiatres américains qui ont attiré l'attention des cliniciens sur les enfants battus. Il a fallu près d'un siècle, un procès retentissant et le support technique de la radiographie pour révéler et convaincre de la réalité des sévices familiaux. La durée de ce dévoilement invite à s'interroger sur la nature des résistances et des défenses qui ont freiné la reconnaissance puis le traitement de cette forme particulière de violence.
Dans ce bref article introductif sont exposés succinctement quelques considérations sur l'étiologie complexe et interactive de la violence intra- familiale, sur la spécificité des rapports au corps de l'enfant réel, sur la réalité du traumatisme non accidentel, sur l'introjection de l'agresseur et l'inclusion réciproque dans l'expérience primitive du corps à corps. En conclusion, quelques réflexions sur les critères déontologiques des intervenants sont évoquées.

Neuropsychologie et schizophrénie

Alain Crombecque y Christian Osiek, Neuropsicología y esquizofrenia.
Las investigaciones sobre los problemas cognitivos de los esquizofrénicos, han tornado desde los años 60, a la neuropsicología, su método y sus instrumentos, siendo uno de sus principales objetivos el de localizar las zonas lesionadas del cerebro a partir de pertubaciones en los tests. Desde entonces, la neuropsicología ha evolucionado, gracias al hecho en particular del desarrollo de modelos que respon- den a los criterios de una neuropsicología cognitiva, orientados sobre la descripción de la organización de los problemas cognitivos, mas bien que sobre la localización de las lesiones cerebrales que las sostienen. Los instrumentos de evaluación utilizados corrientemente no corresponden, no obstante, a dichas evoluciones. En lo que concierne a los trabajos sobre los problemas cognitivos de los esquizofrénicos, solo una minoridad de entre ellos se han inspirado en la neuropsicología cognitiva. El desarrollo de la imaginacion cerebral parece aun haber alentado estos ultimos años, una cierta reviviscencia de la optica localizacionista. Por lo tanto, las conclusiones de las investigaciones orientadas según estos principios siguen imprecisas, tanto en aquello que concierne a la neuropatología, como en aquello también que concierne la naturaleza, la intensidad y la evolución de los problemas cognitivos. Esto resulta, al menos en parte, del uso poco adecuado de los instrumentos. Un análisis cualitativo de los modos de respuesta de los pacientes a los tests y la puesta en relación de sus resultados en los diferentes tests, permiten caracterizar mejor la naturaleza de los problemas cognitivos, cuyos mecanismos y arquitectura, a igual resultado, difieren en los esquizofrénicos y en los pacientes con lesiones cérébrales. Este análisis debe, de todas formas, tener un lugar en una teoría de funcionamiento mental, de la cual la teoría piagetiana puede constituir un modelo.

Nurses Interns' Perception On The Preceptors Role In Enhancing The Interns' Clinical Competence And Transition To Become Competent Staff Nurses In Health Care Settings In The Sultanate Of Oman
Authors: Al-Nasseri Yusra , Al-Maskari Juma , Al-Mamari Khamis 
Published: April 2023

Background: The internship period is considered the mechanism that facilitates easy transition into the role ofbeginning-level staff nurse in an acute-care setting. During this transitional period, it is not only the learning andrefinement of technical skills that interns must master, but also includes maturation into the role of being aprofessionally licensed individual and the inherent responsibilities that accompany licensure (Duchsher, 2001).According to Beecroft, Kunzman, and Krozek (2001). It is through the transition process that the interns acquire thevalue, attitudes, and goals fundamental to the nursing profession and a sense of occupational identity.
Objectives: To assess the perception of new nursing graduates regarding the preceptor's influence in enhancingtheir clinical performance, competence and facilitate graduates' transition.
Methodology: A descriptive quantitative design, Sample: 73 nurses' interns selected from different hospitals. Purposive sampling method was used.
Results: The findings of this study revealed that, the graduates' perceived that, the preceptors do play a vital role infacilitating the graduates' transition in the clinical settings. They also agreed that, the preceptors have a greatinfluence among the graduates' in terms of enhancing their clinical performance, confidence, responsibility,accountability and foster in them positive skills to be competent nurses in their field of practice. The findings alsosuggested that, assigning one preceptor yielded better outcomes than assigning multiple preceptors. In fact, high level of satisfaction was obtained from the graduates with one preceptor more than the other group who wereassigned multiple ones.
Conclusion: The internship period is considered a critical period for the new graduates. Having well planned program to support the graduates as well as assigning one preceptor to them facilitates their transition and enhances their clinical performance. The results illustrated that, the preceptors play a significant role to instill confidence related to skill development and nursing decision making. In addition to that, preceptor's continuity with one graduate builds up a strong relationship between them which resulted towards the end in high level of satisfaction among the graduates.
Recommendation: It is recommended to assign one preceptor only to the intern and shadow the preceptor in allshifts. Furthermore, a Comprehensive orientation program should be organized for the graduates and preceptors as well as a preceptorship programs in order to prepare all preceptors for their roles.

Introduction. In connection with the present volumes of electrification in central Russia, the need for the construction of new electric power transmission lines (EPTLs) has decreased considerably. At the same time, the natural degradation of EPTL supports in time, as well as the prospects for developing the vast expanses of the northern, Siberian and Far Eastern regions, caused by the reorientation of Russia’s economic relations from the West to the East, make it urgent to increase production volumes and technical and economic efficiency of using spun reinforced concrete poles for EPTL supports.Aim. Industrial implementation of spun reinforced concrete poles with the high-strength innovation profile reinforcement by replacing A800 rebars with four-row-profile Au1000P rebars.Materials and methods. The article provides data on the full-scale tests of spun reinforced concrete poles for EPTL supports according to the GOST 22687.1-85 “Centrifugal cylinder reinforced concrete posts for high-voltage transmission lines. Structure and dimensions” [1]. Three pole samples with a length of 26 m were prepared and tested. One sample consisted of prestressed A800 rebars according to GOST 22687.1-85, while the other two prototypes include the prestressed Au1000P rebars with the four-row profile. In the second sample, the reinforcement scheme (diameters and rebar quantity) repeats the standard option, increasing the bearing capacity of the pole. Having the same bearing capacity as the pole, manufactured according to the GOST, the third sample promoted for the reduction in the quantity of non-stressed rebars.Results. A new scheme for reinforcing the pole sample using Au1000P rebars was developed. The results of the sample testing are presented; a comparative evaluation of the pole strength and deformation characteristics is given; technical and economic indicators, as well as the recommendations regarding the reinforcement of the prestressed spun concrete poles with Au1000P rebars are provided.Conclusion. According to the results of the performed study, an economic effect was established due to a reduction in the quantity of non-stressed rebars by 28 %. Poles with Au1000P prestressed rebars have an increased corrosion resistance and durability due to the closing of cracks formed during the impact of short-term dynamic loads from wind gusts, wire breaks, etc. In terms of a recommendation, it is proposed to update the GOST 22687.1-85 in order to use new types of high-strength reinforcement rolled products and higher strength concrete.

Abstract
Selecting the first galaxies at z > 7 − 10 from JWST surveys is complicated by z < 6 contaminants with degenerate photometry. For example, strong optical nebular emission lines at z < 6 may mimic JWST/NIRCam photometry of z > 7–10 Lyman-break galaxies (LBGs). Dust-obscured 3 < z < 6 galaxies in particular are potentially important contaminants, and their faint rest-optical spectra have been historically difficult to observe. A lack of optical emission line and continuum measures for 3 < z < 6 dusty galaxies now makes it difficult to test their expected JWST/NIRCam photometry for degenerate solutions with NIRCam dropouts. Toward this end, we quantify the contribution by strong emission lines to NIRCam photometry in a physically motivated manner by stacking 21 Keck II/NIRES spectra of hot, dust-obscured, massive (

We derive an average spectrum and measure strong narrow (broad) [O iii]5007 and Hα features with equivalent widths of 130 ± 20 Å (150 ± 50 Å) and 220 ± 30 Å (540 ± 80 Å), respectively. These features can increase broadband NIRCam fluxes by factors of 1.2 − 1.7 (0.2–0.6 mag). Due to significant dust attenuation (A
