O ambiente odontológico pode ser considerado um estressor para o público infantil, capaz de desencadear comportamentos indesejados. A Odontopediatria é uma especialidade que exige do profissional o conhecimento de medidas preventivas e de habilidades restauradoras para a realização do tratamento odontológico na criança ou no adolescente. Além disso, é muito importante que o profissional se atente aos sentimentos e às reações da criança, e identifique situações que possam desencadear estresse para o paciente durante o atendimento odontopediátrico, e maneje os comportamentos apresentados. Estudos recentes têm mensurado as reações das crianças e seus sentimentos durante tratamentos odontológicos por meio de técnicas projetivas. Diante da importância do desenho como meio para identificar as emoções das crianças, o objetivo deste estudo foi fazer uma busca na literatura acerca do uso de desenhos como técnica projetiva em Odontopediatria. As técnicas projetivas, com ênfase no desenho, revelaram-se um instrumento eficaz a ser utilizado na prática clínica a fim de melhor compreender as reações apresentadas pelas crianças durante o atendimento odontológico e seu relacionamento com os dentistas. Elas evitam situações inesperadas no consultório e possibilitam maiores chances de se obter um retorno positivo do paciente.

Since 2015 slow-release oral morphine (SROM) is approved for opioid substitution treatment (OST) in Germany. The SROMOS study (efficacy and tolerability of slow-release oral morphine in opioid substitution treatment) evaluates the efficacy and safety of SROM in routine care. This article describes the switching process from racemic methadone, levomethadone and buprenorphine to SROM.Between July 2016 and November 2017 180 patients in 23 study centers in Germany were included in the prospective, non-interventional, naturalistic observational study. Patients were already in OST and switched from a previous medication to SROM. The switching process was analyzed during a period of fourteen days.Data were available for 169 participants. The switching process had a different progression depending on premedication and pre dosage. On the fourteenth day of SROM treatment patients switched from racemic methadone took an average dosage of 922.2 mg/day, from levomethadone 801.0 mg/day and from buprenorphine 626.7 mg/day. Average conversion ratio racemic methadone to SROM was 1:11.8, levomethadone to SROM 1:17.4 and buprenorphine to SROM 1:58.0.This study provides the first data on the switching process from buprenorphine to SROM. Average dose ratio racemic methadone to SROM on the fourteenth day of treatment was considerably higher than recommended in the prescribing information.

Abstract In the framework of the search for dark matter in the form of WIMPs using superheated liquids, a study is conducted to establish a computational procedure aimed at determining how the thermodynamic conditions kept inside a particle detector affect the acoustic signal produced by bubble nucleation. It is found that the acoustic energy injected into the liquid by the growing vapour bubble increases as the liquid pressure is decreased and the superheat degree is increased, the former effect being crucial for the generation of a well-intelligible signal. A good agreement is met between the results of the present study and some experimental data available in the literature for the amplitude of the acoustic signal. Additionally, the higher loudness of the alpha-decay events compared with those arising from neutron-induced nuclear recoils is described in terms of multiple nucleations.

O texto estabelece relações entre a instalação Ten Characters do artista Ilya Kabakov (1933) com o conceito de narrador pensado por Walter Benjamin. Pensa sobre quais elementos envolvem a narrativa na obra de Ilya Kabakov, abordando o trabalho sob aspectos que envolvem uma narrativa que perpassa pela experiência de si e do outro, que é muitas vezes a fonte do narrador. Reflete também sobre o recurso da narrativa na criação dos personagens do artista.

Abstract This randomized parallel-group control trial tested the efficacy of distraction using audiovisual eyeglasses (AVE) during dental procedures [NCT03902158]. Forty-four 6–9 year-old children with low/moderate anxiety and who needed restorative treatment or exodontia of the primary molars were randomly allocated into two groups: the AVE (experimental) and the conventional behavior management techniques (control) groups. Motion sensors were used to measure the participants’ body movements. Dental visits were video recorded, and their pain levels and behavior were assessed using the Faces, Legs, Activity, Cry, and Consolability Behavioral Pain Assessment Scale and the Venham Behavioral Scale, respectively. Anxiety was assessed via heart rate measurements. After treatment, the children scored their pain using the Faces Pain Scale. Mann-Whitney U and chi-square tests were used to compare the groups. The mean score on the behavioral scale was 0.59 in the experimental group and 0.72 in the control group under local anesthesia (p = 0.73). During the procedure, the mean score was 0.41 in the experimental group and 1.32 in the control group (p = 0.07). The mean heart rate was similar in both groups (p = 0.47), but a significant increase during treatment was observed in the control group. There was no difference between the groups in terms of pain, behavior, and self-reported pain scores (p = 0.08). Children aged 6-7 who used the AVE had fewer wrist movements (435.6) than that of children in the control group (1170.4) (p = 0.04). The AVE achieved similar results to the basic behavior management techniques, with good acceptance by the children.

This paper presents specific noise minimization strategies to be adopted in silicon–cell interfaces. For this objective, a complete and general model for the analog processing of the signal coming from cell–silicon junctions is presented. This model will then be described at the level of the single stages and of the fundamental parameters that characterize them (bandwidth, gain and noise). Thanks to a few design equations, it will therefore be possible to simulate the behavior of a time-division multiplexed acquisition channel, including the most relevant parameters for signal processing, such as amplification (or power of the analog signal) and noise. This model has the undoubted advantage of being particularly simple to simulate and implement, while maintaining high accuracy in estimating the signal quality (i.e., the signal-to-noise ratio, SNR). Thanks to the simulation results of the model, it will be possible to set an optimal operating point for the front-end to minimize the artifacts introduced by the time-division multiplexing (TDM) scheme and to maximize the SNR at the a-to-d converter input. The proposed results provide an SNR of 12 dB at 10 µVRMS of noise power and 50 µVRMS of signal power (both evaluated at input of the analog front-end, AFE). This is particularly relevant for cell–silicon junctions because it demonstrates that it is possible to detect weak extracellular events (of the order of few µVRMS) without necessarily increasing the total amplification of the front-end (and, therefore, as a first approximation, the dissipated electrical power), while adopting a specific gain distribution through the acquisition chain.

Ilya e Emilia Kabakov criam obras que adentram a um espaço privado dando a ver a biografia, a imparidade, a narrativa de pessoas e personagens e constroem discursividade. O artigo aborda as instalações Ten Characters e The Toilet, reflete sobre a habitação, as possibilidades de narrativa que vão sendo arquitetadas nas obras e sobre as obras. O texto ainda disserta sobre o intérieur a partir de Walter Benjamin, sobre a elaboração de discursividade de uma obra, pensando as obras como um site-specific por meio de Miwon Kwon e sobre os espaços da habitação com Michel Foucault, permeando a utopia e a heterotopia. Para além de criarem a partir de uma realidade existente, Ilya e Emilia Kabakov elaboram obras que dão espaço para a ficção, os sonhos e os devaneios de uma habitação.
