A comparative evaluation of two chromogenic media for surveillance of carbapenem-resistant Enterobacterales with non-carbapenemase-producing or carbapenemase-producing strains other than blaKPC: blaGES-5, blaNDM-1 or blaVIM-2
Authors: Park Chang-Hun
Published: May 2019

Background

Infections caused by carbapenem-resistant Enterobacterales (CREs) are an emerging problem associated with high rates of morbidity and mortality. CREs are divided into two categories (carbapenemase-producing [CP] CRE and non-CP CRE). The most prevalent carbapenemase produced by Enterobacterales is Klebsiella pneumoniae carbapenemase (KPC) in Korea. Rapid identification of CREs is clinically important in infection control precaution. We compared the performance of two chromogenic media (chromID CARBA agar and CHROMagar KPC agar) for non-CP CREs or CP CREs with blaGES-5, blaNDM-1 or blaVIM-2 in a Korean hospital.

Methods

The study was carried out during a 3-month period from April to June 2017 during the surveillance program for CRE colonization. Antimicrobial susceptibility testing (AST) and polymerase chain reaction (PCR) were performed at the Korean Centers for Disease Control and Prevention.

Results

A total of 45 rectal swabs from 42 hospitalized patients were examined. Sensitivity of both chromID CARBA and CHROMagar KPC were 100% for CP CREs; and 50% and 100% for non-CP CREs, respectively. Specificity of chromID CARBA and CHROMagar KPC were 89.2% and 70.3% for CP CRE, respectively; and 76.9% and 66.7% for non-CP CRE, respectively.

Conclusions

The CHROMagar KPC is useful to monitor non-CP and CP CREs. The chromID CARBA is efficient for rapid detection of CP CREs requiring high contact precaution.
Unsicherheitsabsorption und Resilienz/ Strategien zur Bewältigung von Unsicherheit
Authors: Eickhoff Hajo
Published: May 2019

Weil moderne Menschen ohne Sorge (sicher) sein wollen, wird heute alles einem Sicherheits- Check unterworfen. Unsicherheit kann geistig, aber auch existenziell sein, kann positiv wirken, aber auch negativ. Unsicherheit setzt eine zeitliche Trennung von Reiz und Reaktion voraus, da nur sie Alternativen bietet. Gegen alle Arten von Unsicherheit haben Menschen Strategien entwickelt: Auf Angriffe gegen den Leib aktivieren sie ihr Immunsystem, gegen umfassendere Angriffe setzen sie auf ihre stärkste Abwehrkraft, die Resilienz, die soziale, geistige, leibliche und psychische Elemente umfasst. Hier werden resilienzfördernde Strategien erörtert, die geeignet erscheinen, einen Beitrag zur interkulturellen Offenheit der Menschen und damit zur Gemeinschaftsbildung zu leisten.
Influence of mixing energy on the solid-state behavior and clay fraction threshold of PA12/C30B® nanocomposites
Authors: Aït Hocine Nourredine , Médéric Pascal , Hassan Hanaya
Published: May 2019

This study focuses on the influence of mixing energy on the solid-state behavior and clay fraction threshold of nanocomposites. Thus, three polyamide12/clay (PA12/C30B®) nanocomposites exhibiting different nanostructures were prepared from three sets of processing conditions. Then, thermal and dynamical viscoelastic properties of these nanocomposites were analyzed, in relationship with the material nanostructure and processing conditions. For the first time, the solid-state properties of the nanocomposites revealed the existence of a critical specific mixing mechanical energy. Below this critical value, an increase of mechanical energy refines the structure, improving some end-use properties of the nanocomposite. Above this value, a high mixing energy supply is necessary in order to significantly modify the structure. They also highlighted that the clay fraction threshold, which is commonly attributed to the formation of a three-dimensional percolated network, decreases with increasing specific mixing energy, less significantly when this energy is superior to its critical value.
Effect of Reclaimed Asphalt Pavement and Recycled Asphalt Shingles on Fracture Tolerance of Asphalt Binders

Published: May 2019

Fracture energy density (FED), which is defined as the energy per unit volume required to initiate fracture, is a key property governing the resistance to fracture of asphalt binders. This study evaluated the effect of reclaimed asphalt pavement (RAP) and recycled asphalt shingles (RAS) on virgin binder FED using the binder fracture energy (BFE) test. The objective was to determine whether RAP and RAS can be used with soft virgin binders to achieve satisfactory fracture tolerance. Experimental factors included two RAP sources, two RAS sources (manufacture waste (MW) shingles and tear-off (TO) shingles), and four virgin binders. BFE tests were conducted on blends of virgin and recovered RAP/RAS binders at two binder replacement rates of 15 % and 30 %. Moreover, the Superpave true grade of RAP/RAS binder blends was determined using the dynamic shear rheometer and bending beam rheometer. Results showed that the use of soft virgin binders effectively compensated for the stiffening effect of RAP/RAS in terms of true grade. The addition of RAP binder and MW shingle binder increased the FED of unmodified binders, whereas the opposite trend was observed for TO shingle binder. Furthermore, great caution should be exercised when using virgin polymer-modified binders because significant reductions in FED were observed when RAP and RAS binder was introduced, possibly because of the dilution of polymer modification in addition to stiffening and embrittlement effects. This study indicated that both RAP and RAS are recyclable, according to the Superpave true grade requirements. However, further research is needed to evaluate the effect of the reduction in binder FED caused by TO shingles on mixture fracture performance before its acceptance in asphalt mixtures.

Objective

The pathophysiology of aldosterone-producing adenomas (APAs) has been intensively investigated using genetic and epigenetic approaches. However, the role of miRNAs in APA is not fully understood. The present study profiled miRNAs in APAs as an exploratory approach to elucidate their pathophysiological roles in APAs.

Design

Tissues of APAs and other adrenocortical adenomas were obtained from patients who underwent adrenalectomy.

Methods

Candidate miRNAs differentially detected from samples were examined by whole miRNA sequencing. The expression of candidate miRNAs in APA tissues were further validated by real-time quantitative polymerase chain reaction (qPCR). Further, differential miRNA expression between APAs with and without KCNJ5 somatic mutations was examined. Prediction of miRNA target genes was performed by bioinformatics analysis. For specific miRNAs, correlation analysis between the levels of their target genes and CYP11B2 was analyzed in APA tissues.

Results

Our study determined differential expression of six miRNAs in APA or APA with KCNJ5 mutations. We further demonstrated that miR299 levels were negatively correlated with mRNA levels of CACNB2, which encodes the beta-subunit of the L-type calcium channel. Additionally, we found significant correlations among miR299, CACNB2, and CYP11B2 levels in APA tissues.

Conclusions

Our study suggests the possible pathophysiological involvement of specific miRNAs in calcium signaling and aldosterone hypersecretion in APAs. Further studies, including in vitro analyses, are required to clarify these findings.

ТОПОНІМИ ТА МІКРОТОПОНІМИ НАЦІОНАЛЬНИХ МЕНШИН В ІВАНО-ФРАНКІВСЬКІЙ ОБЛАСТІ
Authors: Паньків Михайло
Published: May 2019

У статті досліджується стан топонімів та мікротопонімів національних меншин на Івано-Франківщині, які проживали і проживають на території області. Дані про них порівнюються із то­по­німією цих етносів в Україні. Коротко подається історія заселення тієї чи іншої національної мен­шини на українській території, зокрема на Прикарпатті.

Активна політика насильницького введення радянським режимом прокомуністичних топонімів завдала значної шкоди українській топонімії. Особливо активно проходила компанія таких перейме­нувань у Східних і Південних регіонах тодішньої УРСР.

У структурі населення регіону протягом його історії чисельністю, особливостями розселення громадським та культурним життям вирізнялися як представники християнських (поляки, німці, угорці, вірмени та ін.), так і не християнських (євреї, караїми, середньовічні представники кочових народів) меншин. Їх заселення розпочалося з часів Київської Русі і проходило кількома хвилями, що було характерним для тої чи іншої меншини.

У 1918–1919 роках Станиславів виконував особливу функцію в рамках нової української держав­ності, будучи столицею новоствореної республіки. Національний характер Станиславова не відрізнявся від статистичної картини міст Східної Галичини, в яких переважали поляки та євреї. Зважаючи на вищевикладене, становище польського населення перед обличчям польсько-української війни було важ­ливим елементом внутрішньої політики Західно-Української Народної Республіки, особливо з ураху­ванням зусиль Державного секретаріату, який прагнув до довіри в очах держав Антанти. Тому непослідовний національний характер міста був величезною проблемою для української влади. Мета цієї статті – показати польсько-українські відносини в Станиславові під час існування Західно-Української Народної Республіки з особливим акцентом на ставленні української влади до польської громади, яка проживала в місті. У роботі показані різні підходи української влади до поляків.

[full article and abstract in Lithuanian; abstract in English]

This article aims to determine the impact of corruption scandals on systemic partisan and legislative changes. The study is based on one case analysis focusing on the MG Baltic corruption scandal, which can be distinguished from other corruption scandals by its systemic large-scale trade of and the impact on political processes in Lithuania. The study uses the triangulation method using both official sources of information and 15 anonymous interviews that helped measure changes in informal politics-business relations in the context of the MG Baltic scandal. The changes are analyzed on three levels: changes in legislation, prevention of corruption within parties, and changes in informal political routines. The analysis confirms the significance of the three variables examined in the study – public discontent, media attention and political leadership – for the implementation of anti-corruption reforms.

Published: May 2019

Peripheral cemento-ossifying fibroma (PCOF) is a reactive gingival over growth, occurring frequently in the maxillary anterior region of teenage and young females. Peripheral cemento-ossifying fibroma (PCOF) is supposed to be originating from periosteum and/or periodontal ligament. A large number of factors have been implicated in the pathogenesis of PCOF, which includes trauma, local irritation, calculus and hormonal disturbances. The definitive diagnosis of PCOF is based upon its clinical, radiological and histological features. Because of the high recurrence rate (8-20%) of PCOF, a close post-operative follow-up is required. Herewith, we are presenting a case of PCOF in 24-year old female patient at an uncommon location.

Skeletal Class III is a malocclusion characterized by anterior crossbite as a result of an abnormal skeletal maxillary and mandibular base discrepancy, which involves disharmony of craneofacial skeleton and profile. The preferred management for children having skeletal Class III malocclusion with retruded maxilla and/or prognathic mandible is the use of devices that encourage the growth and anterior movement of the maxilla bone and/or restrict the exessive mandible growth. The orthopedic treatment consisting of a face mask with rapid maxillary expansion (RME) produces the most dramatic results in the shortest period of time. The purpose of this article is to review a quick correction of skeletal class III maloclussion in the primary dentition through a case example with use of a face mask plus rapid maxillary expansion therapy in a 5 year-old male patient due to a combination of retruded maxilla and protruded mandible, in primary dentition, who was treated with a Petit face mask in conjunction with a bonded RME intraoral appliance added with bite blocks. The first evident occlusal outcomes were a clockwise rotation of the mandible, a positive overjet of 3 mm, a correct overbite, a canine Class I relationship, and a bilateral flush terminal plane. After discussing the present clinical case report and the related published literature, we concluded that skeletal class III malocclusions should be treated as soon as the first clinical signs of abnormal craniofacial growth are recognized, during the first years of life.

In recent years, tissue engineering has evolved considerably, due to the problems in the biomedical area concerning tissue regeneration therapies. Currently, work has been focused on the synthesis and physicochemical characterization of poly lactic acid scaffolds, a synthetic polyester that has been extensively study for its excellent biocompatibility and biodegradability. Moreover, sterilization strategies of scaffold are a crucial step for its application in tissue regeneration, however, the sterilization process have to maintain the structural and biochemical properties of the scaffold. Therefore, it is very important to carry out studies on the sterilization methods of the sample’s material, since translational medicine is intended for in vivo applications. The aim of the present study was designed to analyze the effects of different sterilization techniques, i.e. ethylene oxide (ETO), gamma radiation (GR) and hydrogen peroxide-based plasma (H2O2) in biodegradable PLA scaffolds, and to determine the best sterilization technique to render a sterile product with minimal degradation and deformation, and good tissue response. Analysis of surface morphology showed that ETO and GR modified the PLA scaffolds without any change in its chemical composition. Moreover, the histological response showed that the scaffolds are biocompatible and those sterilized by GR showed a more severe inflammatory response, accompanied with the presence of giant foreign body cells. In conclusion, the results show that among sterilization techniques used in the preset study, the best results were observed with H2O2 sterilization, since it did not significantly modify the surface structure of the PLA fibers and their in vivo response did not cause an unfavorable tissue reaction.

Published: May 2019

Bruxism is defined as a repetitive activity of the chewing muscles characterized by clenching or grinding of the teeth and/or by striking and swinging the jaw. It is of multifactorial etiology and it is considered that there is a physiological bruxism necessary for the development of the face of children. These two aspects complicate the diagnosis that is fundamentally based on a questionnaire to the parents and on the clinical examination of the child. When the physiological wear does not differentiate in time from the parafunctional wear, it has negative consequences in the child that alter their quality of life, requiring an adequate multidisciplinary management.  Considering that it is necessary to know the fundamental characteristics of bruxism in children and adolescents, the objective of this review article is to update its circadian manifestations, classifications, prevalence, etiology, risk factors, diagnosis and treatment that will serve the dentist for the early identification and treatment.

Trans-endodontic implants are an artificial extension through root apex anchored in periradicular bone tissue. The aim is to improve the crown-root ratio and to provide stability to dental organ present. Zirconium oxide (ZrO2) is a material of great technological importance, having good natural color, high strength, high toughness, high chemical stability, does not suffer any corrosion, chemical and microbial resistance and excellent esthetic properties.  Objective: The aim of this study was to evaluate chemical and microscopy of surface conditions of ZrO2 trans-endodontic implant. Materials and Methods: A blocks of ZrO2 were manufactured for produce trans-endodontic implants and divided in two groups: monoclinic and tetragonal phase. They were evaluated using Scanning Electroning Microscope (SEM), Energy-Dispersive X-ray Spectroscopy (EDS), and Atomic Force Microscope (AFM) and Vickers Micro hardness. Results: The Monoclinic phase through AFM analysis showed roughness Ra = 0.320μm, whereas in the Tetragonal phase was 0.126μm, SEM/EDX indicated that the phases are not properly uniform and the addition of the Yttrium to favor the stabilization of the Tetragonal phase. The Vickers hardness analysis showed a value of 1500HV.  Conclusion: The characterization of the surface of trans-endodontic zirconium oxide implants provides a guideline to know the surface characteristics of the material, since a greater roughness on the surface of the implant will favor the Osseo-integration capacity.

Plaque-induced gingivitis is the most common form of periodontal disease and can affect 100% of the population. Gingivitis prevalence in Latin American population is not well documented, therefore the aim of this study was to determine the prevalence and severity of plaque-induced gingivitis in adult populations of three Latin American cities.   Methods: This cross sectional multicenter study included 1650 participants, 550 from the Great Metropolitan Area of Costa Rica (GAM), 550 from Mexico City, Mexico (CDMX) and 550 from Bogota City, Colombia (BC). Subjects completed a questionnaire about their medical history and oral hygiene. Clinical assessment included recording of missing teeth, visible plaque index, calculus recording and gingival index (GI, Loe-Silness index).  Results: Average GI was 1.36. No statistical difference was found between GAM (1.45) and BC (1.48); however, GI in CDMX was significantly lower (1.16). Average gingival bleeding on probing was 43%. Total plaque index was 0.76 showing the highest accumulation at interproximal sites (p=0.0001). A positive correlation was found between plaque and gingivitis (r=0.59). Dental calculus was present in at least one of the 18 evaluated sites per subject with no statistical difference between cities. There was no statistical difference in GI between smokers, former smokers and non- smokers.  Conclusion: Gingivitis prevalence was 99.6%. Moderate Gingivitis was the predominant form, with no statistically significant difference between cities or gender. Dental plaque accumulation was the most important risk factor associated with the establishment of the disease.

Pharmacological Synergism: A Multimodal Analgesia Approach to Treat Dental Pain
Authors: Chavarría-Bolaños MSc, PhD Daniel , Esparza-Villalpando MSc Vicente , Pozos-Guillén MSc, PhD Amaury
Published: May 2019

Dental pain is usually managed by clinical interventions and pharmacological coadjuvants such as NSAIDs. However, its perception and modulation is mediated by different nociceptive mechanisms and these strategies can be insufficient. The multimodal analgesia refers to the use of 2 or more analgesic drugs that attenuate or blockade different mechanisms of pain, obtaining a greater clinical effect. Within this concept, pharmacological synergism plays a leading role, combining different molecules in lower doses to diminish also side effects. Since there are no standard prescriptions to be use in all the patients, multimodal approaches allow the clinician to make responsible effective combinations, individualizing analgesia as the pathway to success.

Non-Carious Cervical Lesions (NCCL) are a current problem of multifactorial origin that is associated with the loss of vertical occlusal dimension, hypersensitivity, loss of teeth, fractures, and many other pathologies that affect the masticatory function of the oral cavity. Identification of the etiological factors of NCCL comprises a key piece for the solution of the problem. Based on clinical scientific evidence related with the diagnosis, a restorative treatment must be planned according to the loss of dental structure in order to return function and aesthetics. The purpose of this case report was to describe a 54-year-old male patient who was diagnosed with generalized NCCL combined with occlusal vertical dimension loss. The protocol of the treatment process is described.

The purpose of this study is to evaluate the effect of thermocycling on the color change of the amine-free dual-cure resin cements. IPS e.max CAD blocs were cut into specimens of 1 mm thickness (N=28) and cemented with one of the 4 different amine-free dual-cure resin cements (NX3 Nexus [NX], Kerr Dental; Variolink Esthetic DC [VE], Ivoclar Vivadent; Panavia V5 [PV], Kuraray Dental; G-CEM Linkforce [GC], GC Corporation) (n=7). A spectrophotometer was used for color measurements. Specimens were subjected to thermocycling (5°C and 55°C; 5000 and 10000 cycles). Normality of data distribution was tested by using the Kolmogorov-Smirnov test. Statistical analysis was performed using a two-way analysis of variance (ANOVA) and Tukey’s multiple comparison tests at a significance level of p<0.05. ∆E values were significantly influenced by the resin cements and the cycle periods (p<0.05). There were no significant differences between NX and VE groups after 5000 thermocycling, however after 10000 thermocycling VE group showed higher ∆E1 values than NX group (p>0.05).  There were no statistically significant differences between the ∆E0 and ∆E1 values of the GC group, however the other groups were affected after 10000 thermocycling (p>0.05). Amine-free resin cements used for cementation showed color change after thermocycling except GC group. All resin cements were showed clinically acceptable color change after thermocycling (∆E < 3.5).

Authors: Şeker R.
Published: May 2019

Purpose: This research was carried out in order to analyze elite athletes’ aim orientation, basic psychological needs and fear of failure in perspective of several variables, and to reveal the differences among these variables. Material and Methods: Sample of the research consisted of elite athletes from different branches who had been in different regions of Turkey in 2016-2017. Number of elite athletes in this research was (n=521) in total, 378 of whom were males and 173 of whom were females. These elite athletes had been chosen by random sampling. As data collection tools, Basic Psychological Needs Scale, which was adapted to Turkish by Kesici et al (2003), Fear of Failure Scale which was adapted to Turkish by Kahraman and Sungur (2016), Scale of Task and Ego Orientation in Sports that was adapted to Turkish by Toros (2004) were used in the study. Results. It was concluded that females had lower fear of “unclear future” and “experiencing shame and embarrassment” than males. It was revealed that as the age of the participants went up, their needs for relationship, fear of unclear future, fear of experiencing shame and embarrassment, and task orientation increase. It was found out that participants who had direct branches had higher “need for relationship” and “fear of unclear future” in comparison with the ones who had indirect branches. Conclusion: According to the results of the study, it was found that there was meaningful difference in sub-dimensional fear of failure in terms of gender variable, in sub-dimensional fear of failure, in basic psychological needs and in aim orientation with regards to age variable, in sub-dimensional basic psychological needs and in fear of failure in terms of branch variation (direct - indirect) variable.

Balancing Dichotomies, Opening Conversations
Authors: Tite Philip L
Published: May 2019

Having known Michel since the first stages of his career, when he was engaged in the study of early Christianity, I have seen him exemplify the role of teacher-scholar for those of us who have attempted to follow in his footsteps. His approach has been to empower students by creating conversations, to balance opposing positions and to allow students to come to their own conclusions (rather than arriving at the “right answer”). This approach not only occurs in the classroom, but also within the academy. Indeed, I propose that Michel’s role as a researcher is largely an extension of his role as a teacher, or co-learner. In this paper, I explore some of the pedagogical implications and lessons that I have learned from Michel’s example as a teacher-scholar. Specifically, I discuss attachment theory, student empowerment, and collaborative pedagogy.

Changing the World without Doing Harm
Authors: Chapman Mark D
Published: May 2019

Some parts of Canada may be moving towards an “open secularism” where matters of faith are less likely to be excluded from public discourse. In such a context, students may become more open about their own faith commitments, more willing to speak out against religious actions they disagree with, and more likely to attempt to change their own traditions. In a confessional context where students are often both leaders and researchers in their own communities it is tempting to use field research as a tool to accomplish pre-defined agendas. Using Paulo Freire’s Critical Pedagogy and its application in Participatory Action Research this paper explores how field research can be taught to activist-oriented insider student researchers in a way that contributes to social change and avoids making research only a platform for their personal agendas.

Varnhagen, Santarém e Avezac: um episódio da polêmica vespuciana (1842-1858)
Authors: Protásio Daniel Estudante
Published: May 2019

Francisco Adolfo de Varnhagen (1816-1878), o visconde de Santarém (1791-1856) e Marie-Armand d’Avezac de Castera-Macaya (1799-1875) foram três historiadores e geógrafos que, no século XIX, escreveram acerca de Américo Vespúcio e suas viagens, sobre as quais hoje ainda imperam mais dúvidas que certezas (quais as que narrou e em quais participou). Com base nos escritos e alguma correspondência daqueles autores, bem como de interpretações posteriores das suas intervenções, procurarei contribuir para um maior conhecimento da polêmica vespuciana, a qual pode ser caracterizada pela teoria do eterno retorno.
Judaísmo messiânico, genealogia e agência: relações entre judeus e não judeus em sinagoga messiânica paulistana
Authors: Ferreira Paula Barbosa da Silva Fontanezzi Leonel
Published: May 2019

Resumo: O caráter peculiar do judaísmo messiânico, que se caracteriza pela conciliação entre práticas judaicas e crença em Cristo, faz com seja frequentemente retratado como movimento ambíguo entre judaísmo e cristianismo e muitas vezes descrito como “ameaça” às fronteiras entre esses sistemas simbólicos e religiosos. O artigo apresenta outro olhar sobre esse movimento religioso a partir de pesquisa etnográfica em sinagoga judaico messiânica paulistana e argumenta que o interpretar como ameaça aos limites entre judaísmo e cristianismo é desconsiderar a relevância que a distinção destes dois sistemas simbólicos e que as categorias “judeu” e “gentio” ocupam no discurso judaico-messiânico que pode ser compreendido não como discurso que extingue diferenças, mas que introduz modos alternativos de ser judeu e de ser gentio.

Authors: Morfín Laura Rebeca Mateos , Flores Carlos , Overmier J. Bruce
Published: May 2019

Abstract The present study was designed to evaluate the use of sensory outcomes (visual vs. auditory) using a differential outcomes procedure to facilitate learning in a many-to-one matching-to-sample task. For one group of participants (differential outcomes) each correct stimulus-choice sequence was always followed by a different outcome; whereas for the rest of participants (non-differential outcomes) each correct sequence was followed by the same outcome. Participants trained with differential outcomes showed a faster acquisition and higher overall accuracy than participants trained with non-differential outcomes. The results provide a new extension the differential outcomes effect by using sensory outcomes and many-to-one matching to-sample task; applications of the differential outcomes procedure are discussed.

Resumo Pode-se supor que a adaptação ao contexto universitário requeira tanto habilidades de relacionamento como comportamentos acadêmicos adequados. Este estudo destinou-se a identificar as relações entre Habilidades Sociais, Vivências Acadêmicas e Comportamentos Sociais Acadêmicos em estudantes. Participaram do estudo 289 estudantes universitários de instituições públicas e privadas, com idades variando entre 17 e 61 anos. Aplicou-se o Inventário de Habilidades Sociais (IHS), o Questionário de Vivências Acadêmicas (QVA-r) e o Inventário de Comportamentos Sociais Acadêmicos (ICSA). Foi identificado que os alunos que apresentam comportamentos sociais acadêmicos desadaptativos também apresentam déficits em habilidades sociais dificultando sua adaptação acadêmica e que, habilidades socialmente aceitáveis estão associadas não só a varáveis pessoais, mas também às curriculares e institucionais.
Os Sentimentos e o Fantasiar em Crianças que Aguardam Cirurgia
Authors: Pfeifer Paula Moraes , Quintana Alberto Manuel
Published: May 2019

Resumo O processo cirúrgico carrega a ideia de agressão, passividade e mobiliza angústias impensáveis. Este estudo qualitativo, descritivo e exploratório investigou as fantasias presentes em crianças no dia anterior à cirurgia. Incluíram-se sete crianças, de ambos os sexos, com idade de cinco a doze anos, internadas para realização de cirurgia em 2014. Utilizou-se como instrumentos lúdicos A Hora do Jogo e o Teste das Fábulas e os dados passaram por análise de conteúdo. Os participantes expressaram a percepção de si enquanto defeituosos e sentimentos de fragilidade, desamparo e diversos medos, bem como fantasias atemorizantes e elaborativas. Concluiu-se que a fantasia manteve seu papel paradoxal: mesmo se constituindo em uma defesa regressiva, revelou-se uma estrutura protetora, auxiliando a atribuir sentido à experiência cirúrgica.

Authors: Vian Mônica , Mosmann Clarisse Pereira , Falcke Denise
Published: May 2019

Resumo A conjugalidade dos cuidadores reverbera no desenvolvimento dos filhos, entretanto, especificidades nessa relação ainda necessitam estudos nacionais. Investigou-se a percepção de adolescentes sobre o relacionamento conjugal de seus cuidadores e quais dimensões da conjugalidade repercutem em sintomas internalizantes e externalizantes dos mesmos. Realizou-se uma pesquisa quantitativa e explicativa. 115 adolescentes responderam ao Familiograma, FBQ, CTS2 e YSR. Verificou-se correlação positiva e significativa entre percepção de conflito e violência conjugal com os sintomas, bem como correlação negativa e significativa de afetividade e aliança parental com sintomas. Violência psicológica conjugal, cometida pela mãe, foi preditora de sintomas internalizantes e externalizantes dos filhos e a aliança parental foi preditora de sintomas externalizantes. Ressalta-se a necessidade de atuação preventiva em núcleos familiares com violência.
