On the Measurement of Electric Resistance of Liquid Electrolytes of Accumulator Battery
Authors: Grinchik N. N. , Dobrego K. V. , Chumachenko M. A.
Published: December 2018

Operational control of parameters of electrolytes (first of all–of specific electric conductivity), is an important electrochemical technology. The methods of measurement of electric conductivity of electrolytes is a subject of permanent discussions because of complexity of physical-and-chemical processes accompanying ion transport and of electrolyte polarization near surfaces of electrodes and of electrochemical processes on the electrodes surfaces. Actual highand low-frequency conductometric methods require relatively expensive equipment and are not free of methodological flaws. In this paper a new method of electric resistance of liquid electrolytes is described and substantiated. It is based on automatic performance of a series of measurements of electrolyte resistance at DC, data processing and extrapolation of an appropriate dependence to threshold voltage at measurement cell plates. The character of functions approximating resistance-applied voltage dependence and method of resistance determination are substantiated. The measurements of specific resistance of some electrolytes were performed. The advantages of the proposed method and measuring device are their simplicity, cheapness, reliability and, consequently, wider possibility to utilize it at technological lines and processes, even at such sites of production processes where such a control was impractical earlier. The method can be widely used for express-diagnostics of electrolytes in such areas as electrochemical energy storage, medicine, agriculture, chemical industry, food production.

La geografía escolar: deseos institucionales y vivencias de aula
Authors: Souto Xosé Manuel
Published: December 2018

La Geografía escolar representa el intento de las instituciones políticas y académicas por sistematizar un contenido escolar, que suponga un objeto de aprendizaje para la población. En este artículo queremos mostrar las diferencias y semejanzas que existen en el análisis de la geografía escolar. Por una parte, el marco curricular y el sistema educativo. Por otra, los dilemas propios del desarrollo de la enseñanza en las aulas de Educación Infantil, Primaria y Secundaria, donde los contenidos de geografía pretenden explicar la descripción del medio a unas personas que, en diversas ocasiones, consideran que está lejos de sus expectativas de comprensión. Pero al mismo tiempo, sus familias y amigos consideran que la razón básica de la geografía escolar consiste en un inventario de lugares con sus recursos.
Unruh effect for interacting particles with ultracold atoms
Authors: Kosior Arkadiusz , Lewenstein Maciej , Celi Alessio
Published: December 2018

The Unruh effect is a quantum relativistic effect where the
accelerated observer perceives the vacuum as a thermal state. Here we
propose the experimental realization of the Unruh effect for interacting
ultracold fermions in optical lattices by a sudden quench resulting in
vacuum acceleration with varying interactions strengths in the real
temperature background. We observe the inversion of statistics for the
low lying excitations in the Wightman function as a result of
competition between the spacetime and BCS Bogoliubov transformations.
This paper opens up new perspectives for simulators of quantum
gravity.
Models on providing food security: case of Ukraine
Authors: Vasylieva Natalia , R. Kruse John
Published: December 2018

Providing food security is a top issue of agricultural economics in a global scale. Although Ukraine helps other countries become more food secure through its exports of wheat, corn, barley, and sunflower, low per capita income levels create challenges for Ukrainians to keep their diet nutrition balance in animal food basket. The research objective supposed applying mathematical apparatus to support solving this problem. The offered consumption optimization model has been developed to ensure inelastic customers’ food preferences by animal products subject to income and calories constraints. The proposed econometric models have been designed to project broiler, pork, eggs, milk, and beef productions. Complex implementation of the set mathematical models maintained the tool to analyze scenarios by expected export/import and demands for grain and oilseed crops used for feed in animal husbandry. The results of this research provide state authorities, livestock and poultry producers, Ukrainian consumers and other interested parties with management guidance focused on developing animal husbandry in the presence of income, as well as animal product price variability.

Heat recovery during treatment of highly concentrated wastewater: economic evaluation and influencing factors
Authors: Corbala-Robles L. , Ronsse F. , Pieters J. G. , Volcke E. I. P.
Published: December 2018

This paper assesses the economics of heat recovery from biological wastewater treatment plants (WWTPs) treating concentrated wastewater, as higher concentrations result in higher heat generation in the treatment basin. A heat balance model has been applied to calculate the amount of recoverable heat from the system and the effect of the heat extraction capacity on the economics of a heat pump installation, evaluated using the internal rate of return. A sensitivity analysis has been performed to evaluate the effect of several parameters on the economics of heat recovery in this type of WWTP: the electricity price, the price of the fuel substituted by heating savings, the investment costs, the coefficient of performance (COP) and the amount of heat extracted from the system. It was calculated that the heat pump capacity has to be high enough to recover a significant amount of heat, but low enough to improve the economics of the system. The economic performance of the system is very dependent on the energy prices of both electrical power to run the heat pump and the fuel (heat) cost substituted by the heat pump.

Authors: Húmpola María Verónica , Rey María Carolina , Spontón Pablo Gabriel , Simonetta Arturo Carlos , Tonarelli Georgina Guadalupe
Published: December 2018

Background:

In the last years, Antimicrobial Peptides (AMPs) and lipopeptides have received attention as promising candidates to treat infections caused by resistant microorganisms.  Objective: The main objective of this study was to investigate the effect of repetitive KLFK motifs and the attachment of aliphatic acids to the N-terminus of (KLFK)n peptides on therapeutic properties.

Methods:

Minimal inhibitory concentration against Gram (+) and (-) bacteria and yeast of synthetic compounds were determined by broth microtiter dilution method, and the toxicity was evaluated by hemolysis assay. Membrane-peptide interaction studies were performed with model phospholipid membranes mimicking those of bacterial and mammalian cells by Fluorescence Spectroscopy. The secondary structure in solution and membranes was determined by Circular Dichroism.

Results:

Our results showed that the resulting compounds have inhibitory activity against bacteria and fungi. The (KLFK)3 peptide showed the highest therapeutic index against bacterial and yeast strains, and the (KLFK)2 peptide conjugated with octanoic acid was the most active against yeasts. All the lipopeptides containing long-chain fatty acids (C14 or longer) were highly hemolytic at low concentrations. The antimicrobial activity of (KLFK)2 and (KLFK)3 lipopeptides was mainly associated with improved stability of the amphipathic secondary structure, which showed high contributions of α-helix in dipalmitoylphosphatidylglycerol (DPPG) vesicles.

Conclusion:

The repetition of the KLFK sequence and the conjugation with lipid tails allowed obtained compounds with high antimicrobial activity and low toxicity, becoming good candidates for treating infectious diseases.

Published: December 2018

Background:

In this study, silver nanoparticles (AgNPs) were synthesized using Banana Peel Extract (BPE), and characterized using UV- Vis absorbance spectroscopy, X-Ray Powder Diffraction (XRD), Atomic Force Microscopy (AFM), and Fourier Transform Infrared Spectroscopy (FTIR). UV-Vis absorbance spectroscopy showed the characteristic plasmon resonance of AgNPs at 433 nm. The synthesized AgNPs were tested for their antibacterial and antioxidant properties.

Methods:

Nanoparticle size (between 5 and 9 nm) was measured using AFM, whereas their crystallinity was shown by XRD. FTIR identified the ligands that surround the nanoparticle surface. The synthesis conditions were optimised using Central Composite Design (CCD) under Response Surface Methodology (RSM). Silver nitrate (AgNO3) and BPE concentrations (0.25-2.25 mM, 0.2-1.96 % v/v respectively), incubation period (24-120 h) and pH level (2.3-10.1) were chosen as the four independent factors. The fitting parameters (i.e. the wavelength at peak maximum, the peak area, and the peak width) of a Voigt function of the UV- Vis spectra were chosen as the responses. The antibacterial properties of the AgNPs were tested against Escherichia coli and Staphylococcus aureus using the tube dilution test. The synthesized nanoparticles were tested for total phenolic composition (TPC) using the Folin - Ciocalteau method, whereas their radical scavenging activity using the 1,1-diphenyl-2- picrylhydrazyl (DPPH) free radical assay.

Results:

An optimum combination of all independent factors was identified (BPE concentration 1.7 % v/v, AgNO3 concentration 1.75 mM, incubation period 48 h, pH level 4.3), giving minimum peak wavelength and peak width. The nanoparticles inhibited the growth of E. coli, whereas S. aureus growth was not affected. However, no superiority of AgNPs compared to AgNO3 used for their fabrication (1.75 mM), with respect to antibacterial action, could be here demonstrated. AgNPs were found to present moderate antioxidant activity (44.71± 3.01%), as measured using DPPH assay, while the BPE (used for their fabrication) presented alone (100%) an antioxidant action equal to 86±1%, something expected due to its higher total phenolic content (TPC) compared to that of nanoparticles.

Conclusion:

Altogether, the results of this study highlight the potential of an eco-friendly method to synthesize nanoparticles and its promising optimization through statistical experimental design. Future research on the potential influence of other synthesis parameters on nanoparticles yield and properties could further promote their useful biological activities towards their successful application in the food industry and other settings.

Published: December 2018

Cardiovascular Disease (CVD) remains the leading cause of morbidity and mortality in
the western world. Hypolipidemic drugs have long been used for the primary and secondary prevention
of heart disease. However, the high frequency of recurrent events in patients despite hypolipidemic
therapy has increased the need for new more targeted therapeutic approaches. Proprotein
convertase subtilisin/kexin type 9 (PCSK9) inhibitors are monoclonal antibodies to the PCSK9
gene and represent a new class of drugs that have been shown to further decrease LDL-C when
administered as a monotherapy or in combination with statins. In addition to LDL reduction,
PCSK9 inhibitors are shown to decrease apolipoprotein B and lipoprotein (a) levels without major
adverse effects. Whether or not PCSK9 inhibitors can actually reduce the incidence of cardiovascular
events and ameliorate CVD prognosis is yet to be clarified. This review summarizes recent
literature on the safety and efficacy of PCSK9 inhibitors on CVD outcome and its potential role in
the management of patients with high-risk cardiovascular disease.

Published: December 2018

Betaine is a methyl group donor that can increase protein synthesis since it has a similar role as methionine. The study was performed to determine the supplementation effect of betaine in the diet containing adequate methionine on growth performance and feed efficiency of female broilers. In total, 200 of day-old chicks of female broiler chickens were allotted to 4 treatments with 5 replicationsof 10 birds. This experiment was designed as completely randomized design. Control diet was formulated to contain adequate methionine (0.50% for starter and 0.38% for finisher period). The other dietary treatments were obtained by supplementing 0.1%, 0.2% and 0.3% betaine. The variables observed consisted of feed, protein and energy consumption, average daily weight gain, feed efficiency, protein and energy efficiency ratio. Supplementation of 0.1% betaine generated a higheraverage daily weight gain (P<0.05), but supplementation at higher levels (0.2 and 0.3%) had no effect on weight gain. However, betaine did not affect feed, energy and protein consumption, as well as feed efficiency and energy and protein efficiency ratio. Thus, betaine can be applied in the diet containing adequate methionine at the level of 0.1% to produce higherdaily weight gain without affecting feed efficiency. Supplementation of betaine at higher levels than 0.1% did not show positive effect on weight gain and feed efficiency in female broiler chickens.

Phenotypic traits of Mexican soybean seeds and their correlation with in vitro shoot induction and susceptibility to Agrobacterium infection
Authors: Mora Vásquez Soledad , García-Lara Silverio , Cardineau Guy A.
Published: December 2018

Background and Aims: Soybean regeneration and transformation are considered highly genotype-specific; however, little is known about desirable seed traits that could be useful indicators of their regeneration and transformation capacities. In the present study, eight commercially available Mexican soybean varieties, as well as the Jack genotype as a control, were phenotypically characterized to determine the seed traits that are important factors for their in vitro performance and susceptibility to Agrobacterium tumefaciens infection.Methods: Grain dimensions, seed weight, moisture, oil, protein, ash, carbohydrate content and macro and micro elements (Mg, K, Ca, P, Na, Mn, Fe, Cu and Zn) were measured and correlated with the corresponding direct shoot organogenesis capability and Agrobacterium infection susceptibility using the cotyledonary node as explant.Key results: Notably, the ash content was the only important factor that inversely correlated with the capacity for shoot organogenesis, whereas carbohydrate and phosphorus content were positively correlated with susceptibility to Agrobacterium infection. The best response in terms of multiple shoot formation and Agrobacterium transient transformation was observed with the soybean varieties Huasteca-100, Nainari and Suaqui-86, which have lower ash content and a higher carbohydrate and phosphorus content.Conclusions: In most reported studies, seed phenotypic traits have been overlooked as factors that influence their regeneration and transformation potential. In the present study, we present evidence of associations between some specific seed traits and regeneration and transient transformation of soybean.
Health Professions’ Digital Education: Review of Learning Theories in Randomized Controlled Trials by the Digital Health Education Collaboration (Preprint)
Authors: Bajpai Shweta , Semwal Monika , Bajpai Ram , Car Josip , Ho Andy Hau Yan
Published: December 2018

BACKGROUND

Learning theory is an essential component for designing an effective educational curriculum. Reviews of existing literature consistently lack sufficient evidence to support the effectiveness of digital interventions for health professions’ education, which may reflect disconnections among learning theories, curriculum design, use of technology, and outcome evaluation.

OBJECTIVE

The aim of this review was to identify, map, and evaluate the use of learning theories in designing and implementing intervention trials of health professions’ digital education, as well as highlight areas for future research on technology-enhanced education via the establishment of a development framework for practice and research.

METHODS

We performed a systematic search of Medical Literature Analysis and Retrieval System Online, Excerpta Medica database, Cochrane Central Register of Controlled Trials (Cochrane Library), PsycINFO, Cumulative Index to Nursing and Allied Health Literature, Education Resources Information Center, and Web of Science for randomized controlled trials (RCTs) published between 2007 and 2016.

RESULTS

A total of 874 RCTs on digital health education were identified and categorized into online-offline, mobile digital education, and simulation-based modalities for pre and postregistration health professions’ education. Of these, 242 studies were randomly selected for methodological review and thematic analysis. Data were extracted by one author using a standardized form, with a (48/242, 20%) random sample extracted by a second author, in duplicate. One-third (81/242, 33.4%) of the studies reported single or multiple learning theories in design, assessment, conceptualization, or interpretation of outcomes of the digital education interventions. Commonly reported learning theories were problem-based learning (16/81, 20%), social learning theory (11/81, 14%), and cognitive theory of multimedia learning (10/81, 12%). Most of these studies assessed knowledge (118/242, 48.8%), skills (62/242, 25.6%), and performance (59/242, 24.3%) as primary outcomes with nonvalidated assessment tools (151/242, 62.4%). Studies with reported learning theories (χ21=8.2; P=.002) and validated instruments (χ21=12.6; P=.006) have shown effective acquisition of learning outcomes.

CONCLUSIONS

We proposed a Theory-Technology Alignment Framework to safeguard the robustness and integrity of the design and implementation of future digital education programs for the training of health professionals.

Authors: Pekdogan Tugce , Akkurt Sedat , Basaran Tahsin
Published: December 2018

The low energy building concept is based on improving the building envelope to reduce heating and cooling loads. Improvements in building envelopes depend not only on climatic conditions but also on insulation. In this study, the thermal performance of external walls was studied by using a three-level full factorial statistical experimental design. An opaque wall in low energy buildings was chosen in order to study the effect of selected factors of city (A), orientation (B), insulation location (C), and month of the year (D) on heat loss or gain. A software was used to calculate the ANOVA table. As a result, all three factors of months of the year, city and orientation of the building fa?ade were found to be significant factor effects for heat transfer. Two-factor interactions of AB, AD, BD, and CD were found to be significant. Therefore, the effects of season, location and orientation were successfully shown to be effective parameters.

Authors: Koyuncu Hakan
Published: December 2018

Fingerprint localisation technique is an effective positioning technique to determine the object locations by using radio signal strength, values in indoors. The technique is subject to big positioning errors due to challenging environmental conditions. In this paper, initially, a fingerprint localisation technique is deployed by using classical k-nearest neighborhood method to determine the unknown object locations. Additionally, several artificial neural networks, are employed, using fingerprint data, such as single-layer feed forward neural network, multi-layer feed forward neural network, multi-layer back propagation neural network, general regression neural network, and deep neural network to determine the same unknown object locations. Fingerprint database is built by received signal strength indicator measurement signatures across the grid locations. The construction and the adapted approach of different neural networks using the fingerprint data are described. The results of them are compared with the classical k-nearest neighborhood method and it was found that deep neural network was the best neural network technique providing the maximum positioning accuracies.

Authors: Yaman Gulsen , Altay Ramazan , Yaman Ramazan
Published: December 2018

Many industrial products work under different constraints. Examples of these products include transformers and keeping them in certain operating temperatures is an important design constraint. However, since power transformers have different requirements, there are no standard products. For this reason, it is difficult and costly to test each one by considering these constraints and to design them accordingly. Satisfactory thermal analysis using a 3-D finite volume-based CFD model is an important step to understand natural convection and necessary design modifications under the desired conditions. The aim of this study is to verify the performance and reliability of the design by comparing the experimental results with 3-D finite volume analysis results by considering cooling of a dry resin type transformer with a cabin. The effect of the cabin on the product in terms of natural heat convection is also evaluate

Authors: Ozener Orkun , Ozkan Muammer
Published: December 2018

The reducing of real driving emissions from public transportation which is using intracity lines has become more important in recent years. This is because the petroleum derived fuel combustion products contributes the global warming as well as adversely the air quality. The fuel consumption perspective is another major economical concern for operating companies that should be optimized. In this context a part of Istanbul Metrobus public transportation system of which is using fully a dedicated line is assessed via on board emission and fuel metering devices for two loading conditions. The relevant vehicle and engine operating data is logged during the tests. The logged data is post processed for developing the average emission factors. The results are also analyzed from acceleration and altitude change perspective and alternative scenarios are discussed for cleaner and economic operation. Lastly the in-service conformity parameters are identified and the results are compared with homologation values. It was found that for the same velocity, acceleration affect was found significant and the critical acceleration level is determined as 0.4 m/s?. For NOx, and CO emissions velocities smaller than 20 km/h and 40 km/h was found dominant at positive acceleration zones. Also for fuel consumption and CO2 emission levels the velocities higher than 30 km/h was found critical for all positive acceleration levels. It was shown that the real driving and emission data can be used efficiently for developing more environmentally friendly engine calibrations and decreasing fuel consumption and emissions.

O fotografar: uma resposta sublimatória à tensão pulsional?
Authors: Silva Isis Graziele da , Menezes Lucianne Sant’Anna de
Published: December 2018

Partindo da experiência de uma das autoras como fotógrafa profissional, este trabalho objetiva examinar como a psicanálise poderia colaborar na abordagem da fotografia em relação ao trabalho, investigando possíveis articulações do fotografar com a sublimação das pulsões. Trata-se de uma pesquisa psicanalítica no campo da psicanálise em extensão. Os resultados mostraram que, para Freud, o trabalho é um instrumento poderoso para o homem no combate ao sofrimento, além de inseri-lo na comunidade humana, podendo ser meio de sublimação. Quando o trabalho é fonte de sublimação, coincide com a criação artística, que também é apontada por Freud como uma significativa forma de deslocamento libidinal, e a fotografia abarca estas duas características, sendo um ofício e também uma forma de arte. Foi possível compreender que, sendo escolhido livremente e estando o fotógrafo eroticamente ligado ao trabalho, o fotografar pode propiciar a satisfação pulsionalpor meio da sublimação de componentes sexuais e agressivos.
A mentira contada em análise
Authors: Schivartche Marcia
Published: December 2018

O presente artigo procura compreender a função da mentira contada em análise, bem como refletir sobre o manejo transferencial solicitado por tal tipo de relato, à luz da teoria psicanalítica freudiana. Com esses objetivos, efetuou-se um estudo sobre as realidades psíquica e material, a fantasia e a mentira, a fim de poder analisar a incidência do referido relato na clínica psicanalítica e como escutá-lo, desvinculando-o de um viés moralista e atrelado ao desejo. Pretende-se com este artigo esclarecer que, para a clínica, o aspecto da função do mentir que importa é sua forma e não seu conteúdo, além de propor um espaço benevolente para escutar, a partir da livre associação, o discurso mentiroso dos pacientes. Essas reflexões podem contribuir de forma significativa para o aprimoramento do fazer do analista na clínica psicanalítica.
Avaliação psicossocial no contexto das normas regulamentadoras do trabalho: desafios e práticas profissionais
Authors: Rodrigues Carlos Manoel Lopes , Faiad Cristiane
Published: December 2018

A obrigatoriedade da avaliação psicossocial para trabalhadores submetidos a situações de trabalho com combustíveis, de trabalho em altura e de trabalho em espaços confinados configura-se um campo recente na prática profissional da psicologia no Brasil. Poucos são os estudos na área e a compreensão sobre os procedimentos que ora são utilizados no Brasil. Neste sentido, o presente estudo tem como objetivo identificar como esta avaliação tem sido realizada no Brasil. Para tanto, foram entrevistados 40 profissionais que atuam nesta prática, sendo 95% mulheres e de todas as regiões brasileiras. Os resultados apontam a utilização majoritária de entrevistas e testes psicológicos para avaliação de aspectos cognitivos, personalidade e das condições de saúde mental. Foram relatadas dificuldades quanto ao número de testes disponíveis ou específicos para este contexto, e a pouca integração da avaliação junto a outras profissões da área de saúde ocupacional. Identificou-se a necessidade de estudos relativos a adequação dos instrumentos utilizados para este fim, e a identificação das características a serem avaliadas para cada cargo.
A responsabilidade do Estado na perspectiva da legislação da Defesa Civil e de lideranças comunitárias
Authors: Spink Mary Jane Paris , Manesco Henrique Mota
Published: December 2018

Esta pesquisa buscou compreender a responsabilidade do Estado na gestão de risco de desastres sob a perspectiva de lideranças comunitárias do M’Boi Mirim. Tendo em vista que a região conta com 50 das 407 áreas de risco do município de São Paulo, estando entre os piores índices de exclusão e vulnerabilidade da cidade, e que compete às prefeituras gerenciar áreas de risco, verifica-se a importância de compreender a responsabilidade do Estado neste contexto. Foram analisadas entrevistas de três lideranças comunitárias da região. Desta análise emergiram diversos elementos que contribuem para a situação da região: a inércia do poder público, as dificuldades de diálogo entre população e autoridades governamentais e a diversidade de atores que interferem na solução das questões encontradas, como secretarias municipais que não conversam entre si, políticos que atuam de acordo com seus próprios interesses e a onipresença do tráfico. Verificou-se, ainda, que as lideranças tinham uma perspectiva crítica tanto com relação às ações ou inércia do governo como também com relação à responsabilidade da população.
A construção de saberes e práticas em Psicologia no Centro de Referência Especializado de Assistência Social (CREAS) de Guapimirim, Rio de Janeiro
Authors: Luz Rafael Reis da
Published: December 2018

O presente artigo tem como objetivo apresentar e discutir saberes e práticas em Psicologia na política de assistência social, em especial no Centro de Referência Especializado de Assistência Social (CREAS), equipamento da atenção especial de média complexidade. Tal proposta surge diante do estranhamento de certa Psicologia que, atrelada a um projeto de modernidade, constitui-se como um saber endurecido em sua forma identitária, não se sustentando no campo da assistência social. Para tanto, apoiamo-nos em legislações e resoluções da política de assistência social, em alguns aportes teóricos e realizamos uma breve exposição da experiência profissional no CREAS de Guapimirim, município do Estado do Rio de Janeiro. Apontamos, por fim, a necessidade de se pensar em uma clínica psicológica para além do sujeito. As diferentes atividades realizadas no CREAS podem ser pensadas como dispositivos geradores de efeitos clínicos, contribuindo, assim, para práticas em psicologia. Tais atividades podem ser também práticas psicológicas. Não obstante, reconhecer a amplitude de seu lugar é, talvez, o maior desafio da Psicologia na política de assistência social.
Percepção de mulheres sobre o parto e o papel da doula
Authors: Silva Lorena Carla Cardoso , Corrêa-Cunha Elza Francisca , Kappler Stella Rabello
Published: December 2018

Os cuidados oferecidos pela doula, profissional que orienta e assiste a mulher na gestação, no parto e no pós-parto, são considerados como acolhedores e tendem a promover o bem-estar emocional da parturiente, auxiliando-a no enfrentamento das situações de desconforto. O objetivo dessa pesquisa foi analisar a percepção de mulheres sobre o parto e sobre a figura da doula no processo de parturição. Foram entrevistadas nove mulheres, com idades entre 19 a 35 anos, que tiveram uma gestação de baixo risco e que foram acompanhadas por doulas durante a gestação, parto e/ou no período pós-parto. Os relatos foram transcritos na íntegra e emergiram três categorias finais: Práticas Institucionais e Ambiência; Enfrentamento da Dor; e Presença da Doula e Importância da Equipe. Concluiu-se que a doula cumpre um papel importante ao proporcionar confiança e ao utilizar técnicas para o alívio da dor, entretanto, cabe ressaltar que apenas a sua presença não garante o respeito pelos direitos e individualidade das mulheres e um parto humanizado.
Intervenções para o TDAH infanto-juvenil que incluem pais como parte do tratamento

Published: December 2018

O Transtorno de Déficit de Atenção e Hiperatividade (TDAH) é um diagnóstico frequente em crianças em idade escolar e exige atenção para as consequências no desenvolvimento infantil. Existem diversas linhas de tratamento para o transtorno, especialmente a medicamentosa e a psicossocial. Entretanto, evidências atuais sugerem que a presença de TDAH em crianças pode estar associada a disfuncionalidades na família, relações entre pais e filhos, psicopatologia parental e diminuição da autoeficácia parental. Este artigo de revisão teórica investigou intervenções relacionadas à inclusão de pais como parte do tratamento da criança com TDAH. A literatura analisada relacionou-se a opção e adesão dos pais ao tratamento; estudos que investigaram a eficácia para intervenções com pais como alternativa de tratamento do TDAH nos filhos; e sobre barreiras e acessos às intervenções que os incluem como parte do tratamento da criança com TDAH. Existem significativas evidências de que a inclusão dos pais no tratamento da criança com TDAH traz benefícios para pais e crianças. Pais adquirem habilidades em relação ao conhecimento e manejo do transtorno e aprendem a auxiliar a criança em relação a diferentes aspectos diminuindo sintomas, favorecendo o desenvolvimento infantil e melhorando relações entre pais e filhos.
