Objective@#The purpose of this study was to investigate the differences in the anti cyclic fatigue performance of Woride KS (WKS), Proteper Gold (PTG), and Hyflex CM (HCM) nickel titanium instruments with different tip diameters in curved root canal models, and to provide reference for the targeted selection of suitable nickel titanium instruments in clinical preparation of curved root canals.

Validation of the Brazilian version of the Short Inventory of Grazing (SIG)

Abstract Objective Grazing is a disturbed eating pattern that has been associated with eating disorders and obesity. One of the new measures to investigate this eating behavior is the Short Inventory of Grazing (SIG), a two-item questionnaire that assesses grazing in general and grazing associated with the feeling of loss of control over eating (LOC grazing). However, the psychometric properties of the SIG have not been assessed in the Brazilian population. The present study aimed to cross-culturally adapt and validate a Brazilian version of the SIG. Methods The SIG was adapted to the Brazilian context following international guidelines. Then, 90 undergraduate students completed an online survey including questions from the SIG, the Binge Eating Scale (BES), the Patient Health Questionnaire-9 (PHQ9), the Generalized Anxiety Disorder-7 (GAD7), and a question related to self-reported health status. The internal consistency, test-retest reliability, and convergent validity of the questionnaire were assessed. Results The prevalence rates of at least one weekly episode of grazing in general and LOC grazing were 71.1 and 54.5%, respectively. The internal consistence of the SIG was acceptable (0.81). In addition, SIG scores on both items were positively and significantly associated with BES, GAD7, and PHQ9 scores, and with poorer self-rated health. However, SIG test and retest scores differed significantly. Conclusion Overall, the Brazilian version of the SIG demonstrated adequate psychometric properties. The instrument had adequate internal consistency, with both items exhibiting good convergent validity with related measures.

Using manual versus mechanized glide path instruments and ProTaper Gold versus ProTaper Next systems in curved canals: micro-CT study

Abstract The aim of this study was to evaluate the root canal shaping effect of ProTaper Gold (PTG) versus ProTaper Next (PTN) instrumentation systems, and of a manual #15 K-type file (K15) versus the ProGlider (PG) mechanized instrument for glide path creation, in severely curved mesial canals. Twenty-four mandibular molars with two separate mesial canals were anatomically matched using computed tomographic scanning, and then divided into two groups (n=12) according to the glide path instrument used, either K15 or PG. In all teeth, the PTG system was used to prepare the mesiobuccal canal, and the PTN, the mesiolingual canal. The teeth were scanned by computed microtomography, before and after root canal preparation, and the values of the initial volume, final volume, volumetric variation, untouched walls, and canal transportation variables were determined. The data were analyzed using the two-way ANOVA test, and the Tukey test for multiple comparisons. There was no significant difference among the study groups regarding volumetric variation or root canal transportation, either in the cervical, middle or apical thirds, or in the entire root canal (p>0.05). In the apical third, the percentage of untouched walls was significantly higher in groups using K15 than in those using PG (p<0.05), namely 33.144% and 23.285%, respectively, irrespective of the instrumentation system. In the other regions, there was no difference between K15 and PG regarding this variable. It was concluded that PG was associated with a lower rate of untouched walls in the apical region than K15.

Translation and cultural adaptation of the Positive Aspects of Caregiving Scale for caregivers of people living with dementia in Brazilian context: a methodological study

ABSTRACT BACKGROUND: The Positive Aspects of Caregiving (PAC) scale is used to assess psychosocial benefits provided to caregivers by the task of caring. The PAC scale consists of nine items, assessed using a five-point Likert scale, with higher values indicating greater positive perceptions and gains from the caregiving experience. OBJECTIVE: To translate and culturally adapt the PAC scale for informal Brazilian caregivers of people with dementia. DESIGN AND SETTING: A methodological study was conducted at the Federal University of São Carlos. METHODS: The following stages were carried out: Translation; Synthesis of the translations; Back-translation; Evaluation by an experts' committee; and Pre-test. RESULTS: Two independent professionals translated the PAC scale. The consensus version was obtained by merging both translations, which were back-translated into English by a third translator. The expert committee comprised three specialists in the area and project researchers. All scale items presented a Content Validity Index of 1 (CVI = 1.0), and thus remained in the pre-final version of the instrument. The instrument was pre-tested with seven caregivers of people with dementia, the majority of whom were women (57.1%), with a degree of kinship corresponding to sons/daughters (57.1%) and an average age of 55.2 (± 4.1) years. The caregivers considered it clear and understandable and made no suggestions for changes. CONCLUSION: The PAC scale was translated and culturally adapted for use by informal caregivers of people with dementia in Brazil. However, a psychometric analysis of the instrument is necessary to provide normative data for this population group.

O que é autoestima para os analistas do comportamento? Uma revisão sistemática / What is self-esteem for behavioral analysts? A systematic review

A autoestima é um termo muito utilizado pelas pessoas no senso comum, mas ainda são necessários mais estudos para entendê-lo sob o ponto de vista comportamental. O objetivo deste estudo foi realizar uma revisão de textos da Análise do Comportamento a respeito de autoestima. Foi realizada uma busca em três fontes diferentes: periódicos exclusivos de Análise do Comportamento; as coleções de livros Sobre Comportamento e Cognição e Comportamento em Foco; e na Scielo. No total, 16 textos preencheram os critérios, que eram a) ter a palavra "autoestima" no título b) ser um texto da Análise do Comportamento. Foram discutidas as definições de autoestima utilizadas, os participantes dos estudos, os estímulos usados em testes de medida implícita e os principais resultados. Nenhum dos textos analisados utilizou intervenções voltadas ao aumento da autoestima. Apesar de serem textos da abordagem comportamental, muitos dos estudos utilizam apenas definições e instrumentos não comportamentais. As principais conclusões da revisão foram: 1) ainda existem poucos estudos sobre autoestima na Análise do Comportamento; 2) ainda não existe uma definição comportamental bem construída, especialmente na literatura internacional.

Self-esteem is a term that is widely used in common sense, but more studies are still needed to understand it from a behavioral point of view. The objective of this study was to carry out a review of Behavior Analysis papers regarding self-esteem. A search was conducted in three different sources: Behavior Analysis journals; the book collections Sobre Comportamento e Cognição and Comportamento em Foco; and on Scielo. In total, 16 texts met the criteria, which were a) having the word "self-esteem" in the title and b) being a Behavior Analysis text. We discuss the definitions of self-esteem used, the participants in the studies, the stimuli used in the implicit measurement tests and the main results. None of the analyzed texts used interventions aimed to increase self-esteem. Even though they are texts of the behavioral approach, many of the studies only use non-behavioral definitions and instruments. The main conclusions of the review were: 1) there are still few studies on self-esteem in Behavior Analysis; 2) there is still no well-constructed behavioral definition, especially in international literature.

Resumen Con la finalidad de evaluar la presencia de insatisfacción corporal en jóvenes varones, resulta importante contar con instrumentos adecuados que midan esta insatisfacción y que garanticen resultados válidos. En el Perú y en diversos países, no se cuenta con gran variedad de herramientas apropiadas que midan la insatisfacción de la imagen corporal en varones, por lo que el propósito de la investigación fue adaptar lingüística y psicométricamente el BSQ en un grupo de jóvenes varones universitarios (n=320) de Lima Metropolitana con un rango de edad de 18 a 30 años. Se obtuvo una explicación del 50.72% sobre la variabilidad del instrumento y los resultados mostraron una excelente consistencia interna en ambos factores: 1) Malestar Corporal Normativo (α= .88) y 2) Malestar Corporal Patológico (α= .87). Respecto a la validez convergente y divergente, el BSQ demostró una buena capacidad para determinar la presencia de insatisfacción de la imagen corporal denotando una convergencia positiva y significativa entre ambos factores del BSQ con el Afecto Negativo del SPANAS, explicando como todos estos sentimientos negativos se encuentran presentes e influyen con la aparición de esta incomodidad. Se discuten las limitaciones y recomendaciones del estudio, y la dirección de futuras investigaciones.

Abstract In order to evaluate the presence of corporal dissatisfaction in young men, it is important to have adequate instruments to measure this dissatisfaction and guarantee valid results. However, in Peru and several countries, there is not a great variety of appropriate tools to assess body image dissatisfaction. The present research aimed to adapt the Body Shape Questionnaire (BSQ) to a group of young male university students (N = 320) from Metropolitan Lima with an age range of 18 to 30 years. Results showed a 2-factor structure that explained 50.72% of the total variance. An excellent internal consistency was obtained in both factors: 1) Normative Body Uncomfort (α = .88) and 2) Pathological Body Uncomfort (α = .87). Regarding convergent and divergent validity, the BSQ showed good ability to determine the presence of body image dissatisfaction, denoting a positive and significant convergence between both BSQ factors with the PANAS Negative Affect, explaining how all these negative feelings are present and influence with this discomfort. Finally, the limitations and recommendations of the study, as well as the direction of future research are discussed.

ASSESSMENT OF TORSION RESISTANCE OF GLIDE PATH ROTARY INSTRUMENTS

NiTi endodontic instruments for glide path are the most susceptible to fractures inside the root canal, mainly as a result of high torsional stress. Objective: The present study investigated the resistance to torsion and angular deflection of instruments destined for the glide path: ProGlider #16.02; T-File #17.02 and the MK Life #16.02. Materials and methods: Thirty rotating NiTi glide path instruments (n=10) with 25mm lengths were selected. The torsion test was performed based on ISO 3630-01 (1992). Three millimeters from the tip of the instruments, it was attached to a small load cell by a lever arm connected to the torsion shaft. Torsional strength and angular deflection were evaluated. Fracture surfaces were examined by scanning electron microscopy with magnifications of 1000x and 5000x in the cross section, and 50x in the lateral section. Statistical analysis was performed using the Kruskal-Wallis H test, followed by the Down's post hoc test. Results: The ProGlider instrument showed greater torsional strength (p<0.05) compared to the T-File (p<0.05) and MK Life (p<0.05), respectively. However, the T-File showed greater angular deflection (p<0.05) than the other groups tested. Conclusion: It can be concluded that the ProGlider instrument presented greater torque for the fracture, while the T-File instrument presented greater angular deflection.

Influence of mixing parameters in STAR automatic sample processing instruments on the detection results of internal controls / 中国输血杂志

【Objective】 To explore the significance of blending internal controls by automatic sample processing instruments in the enzyme linked immunosorbent assay (ELISA). 【Methods】 The internal controls were vortexed and mixed before the test, and then were added to the same ELISA plate by the STAR automatic sample processing instruments under the same detection conditions. The difference of S/CO value of internal controls with and without sufficient blending via the sampling needle and their frequency distribution were compared. Internal controls that were greatly affected by mixing parameters were submitted to the same test with different batches of reagents from the same manufacturer, and the results were analyzed for consistency. 【Results】 The S/CO value of anti-HCV internal controls without blending using adding sample needle was significantly lower than that of quality control samples with sufficient blending (P<0.000 1). The S/CO values of unmixed internal controls concerning anti-TP and anti-HIV detection given by some detection systems were also different from the values of mixed internal controls (P<0.05). Some of the S/CO values of the anti-HCV internal controls without mixing were distributed within the interval of less than 2. Different batches of reagents from the same manufacturer were used to detect anti-HCV internal controls, and there were differences in the partial detection values between the mixed and unmixed internal controls (P<0.05). 【Conclusion】 Although the internal controls were mixed by vortex shock before the test, the detection results of some internal controls will still be affected when the STAR automatic sample processing instruments does not set the mixing parameters for internal controls.

Evaluation of Muscle Fatigue in Spinal Surgery Instruments Based on sEMG-JASA / 中国医疗器械杂志

Based on the joint analysis of EMG spectrum and amplitude method (JASA), a study on muscle fatigue assessment of spinal surgical instruments based on surface EMG signals was carried out, and a comparative evaluation of the operating comfort before and after the optimization of spinal surgical instruments was completed. A total of 17 subjects were recruited to collect the surface EMG signals of their brachioradialis and biceps. Five surgical instruments before and after optimization were selected for data comparison, and the operating fatigue time proportion of each group of instruments under the same task was calculated based on the RMS and MF eigenvalues. The results showed that when completing the same operation task, the operation fatigue time of the surgical instruments before optimization was significantly higher than that after optimization (P<0.05); there was no significant difference in the fatigue status of brachioradialis and biceps when operating the same instrument (P>0.05). These results provide objective data and reference for the ergonomic design of surgical instruments and fatigue damage protection.

Influence of traverse and waveone gold glider glide path files on the amount of apically extruded debris / Influência das limas glide path Traverse e Wave One Gold Glider na quantidade de detritos extruídos apicalmente

Objective: The aim of this study was to evaluate the effect of different glide path files on the amount of apically extruded debris. Material and Methods: Sixty single-canaled mandibular premolars were accessed and randomly divided into three groups (n= 20) according to the file used for glid path creation; group A using Traverse file, group B using WaveOne Gold Glider, group C using stainless steel K file. All teeth were then instrumented using the Reciproc system. The debris extruded apically during instrumentation were collected into pre-weighed Eppendorf tubes which were then stored in an incubator at 70 °C for 5 days. The weight of the dry extruded debris was established by subtracting the pre-instrumentation and post instrumentation weights of the Eppendorf tubes. The data were analyzed using one-way ANOVA test, and post hoc analysis. Results: WaveOne Gold Glider produced the least amount of apical extruded debris (0.41±0.25) followed by the Traverse group (0.59±0.20) then the K-file group (0.64±0.16) with a statistically significant difference (p=0.003). Conclusion: Apical extrusion of debris is inevitable during root canal cleaning and shaping. Creation of glide path using engine-driven files produces less amount of apically extruded debris compared to hand-driven K-files. (AU)

Objetivos: O objetivo deste estudo foi avaliar o efeito de diferentes limas glide path na quantidade de detritos extruídos apicalmente. Metodologia: Sessenta pré-molares inferiores com canal único foram acessados e divididos aleatoriamente em três grupos (n= 20) de acordo com a lima utilizada para criação do glid path; grupo A usando lima Traverse, grupo B usando WaveOne Gold Glider, grupo C usando lima K de aço inoxidável. Todos os dentes foram então instrumentados usando o sistema reciprocante. Os detritos extruídos apicalmente durante a instrumentação foram coletados em tubos Eppendorf pré-pesados que foram então armazenados em uma incubadora a 70°C por 5 dias. O peso dos detritos secos extruídos foi estabelecido subtraindo-se os pesos dos tubos Eppendorf antes e após instrumentação. Os dados foram analisados por meio do teste one-way ANOVA e análise post-hoc. Resultados: WaveOne Gold Glider produziu a menor quantidade de detritos apicais extruídos (0,41±0,25) seguido pelo grupo Traverse (0,59±0,20) e depois pelo grupo K-file (0,64±0,16) com uma diferença estatisticamente significativa (p=0,003). Conclusão: A extrusão apical de detritos é inevitável durante a limpeza e modelagem do canal radicular. A criação do glide path usando limas acionadas por motores produz menos quantidade de detritos extruídos apicalmente em comparação com as limas K manuais. (AU)

Reliability was evaluated with the Kuder-Richardson coefficient, Kaiser-Meyer-Olkin test and Bartlett's sphericity test. The data were processed in SPSS version 21. RESULTS: The instrument was applied to 66 resident physicians with a mean age of 28.5 ± 0.7 years. The Kuder-Richardson coefficient was 0.608. The Kaiser-Meyer-Olkin and Bartlett tests showed that it was a multidimensional instrument. CONCLUSIONS: A valid, reliable and multidimensional instrument was obtained to determine the level of knowledge in relation to the application of Salinas forceps in Gynecology and Obstetrics residents.

Improving the Quality of Residency Programs in Family and Community Medicine / Aprimorando a qualidade de Programas de Residência em Medicina de Família e Comunidade

ABSTRACT OBJECTIVE To develop and present an instrument to evaluate and monitor the quality of medical residency programs in residencies in family and community medicine (FCM) based on preceptors and residents, considering the insertion of the health network program. METHOD The instrument was developed in three stages: 1) interview with the preceptors of FCM; 2) literature review; and 3) production, adequacy, and approval of the evaluation instrument by renowned professionals of the Brazilian FCM. The third stage included 9 people and used the Delphi technique with 80% agreement. For the qualitative results, Bardin's Content Analysis was used. RESULTS In all, there were five evaluation cycles to adapt the proposed recommendations, with the elimination of one item and weighting, with a results analysis methodology of 10 resulting items, reaching an expected matrix for organizing residency programs in the health network, divided into 3 domains: Organization of the Unit, Human Resources, and Preceptor-resident relationship. CONCLUSION An instrument for evaluating and monitoring residency programs in family and community medicine can be a tool to facilitate program managers and allow evaluation and monitoring, continuously qualifying them.

RESUMO OBJETIVO Desenvolver e apresentar um instrumento para avaliar e monitorar a qualidade de programas de residência médica em medicina de família e comunidade (MFC) a partir dos preceptores e residentes, considerando a inserção do programa de rede de saúde. MÉTODO A elaboração do instrumento foi desenvolvida em três etapas: 1) entrevista com preceptores em MFC; 2) revisão da literatura; e 3) produção, adequação e aprovação do instrumento avaliativo por profissionais renomados na MFC brasileira. A terceira etapa contou com nove pessoas e utilizou a técnica Delphi com obtenção de 80% de concordância. Para os resultados qualitativos foi utilizada a análise de conteúdo de Bardin. RESULTADOS Ao todo ocorreram cinco ciclos de avaliação para adequação das recomendações propostas, com eliminação de um item e ponderação, e metodologia de análise de resultado de dez itens resultantes. Atingiu-se uma matriz esperada para a organização de programas de residência na rede de saúde, dividida em três domínios: organização da unidade, recursos humanos e relação preceptor-residente. CONCLUSÃO Um instrumento de avaliação e monitoramento de programas de residência em MFC pode ser uma ferramenta para auxiliar gestores de programas e permite a avaliação e monitoramento, qualificando-os continuamente.
