title: A Study of the styles and characteristics of basic music theory textbooks in China in the past 100 years

description: Abstract: Due to various historical and realistic reasons, the development of basic music theory in China lags behind in the teaching system, teaching content and other aspects. It is an important task for Chinese music workers to revise or supplement the current basic music theory and related textbooks and then build a discipline system of basic music theory in China. This paper synthesizes the theories of music education and music history, music culture, music morphology and other related disciplines. It uses scientific, objective and rational values and holistic and comprehensive concepts. It takes the development of the basic music theory education of China as the research object and takes history as a mirror to further consider and prospect the construction of the basic music theory discipline system of China. The basic theory of Chinese Music can be roughly divided into three stages: (1) The basic music theory from the early 20th century to the founding of the People’s Republic of China; (2) From the founding of the People’s Republic of China to the period of reform and opening up; (3) Basic music theory compiled and published since the reform and opening up. It can be seen, from the development of the basic theory education of Chinese Music and its teaching materials, that the development of western music theory in China, before the founding of the People’s Republic of China, was a process from passive acceptance to active absorption. The scope of spreading western music theory was from the palace to the church, then to the school, and, finally, to the society, which made the music theory teaching in China gradually develop into a major and minor system as the leading mode. The basic theory of Chinese Music gradually deviated from its own track. With the deepening of music research after the founding of the People’s Republic of China, the discipline development of basic music theory has witnessed a prosperous situation, and the construction of basic music theory is moving towards the direction of diversification and deepening. Many musicologists and music educators have made contributions to the construction of basic music theory in China from different disciplines and research perspectives. Based on the principle of “combining history with the theory” and combing the development of basic music theory in China, the ideal model of Chinese music theory discipline construction is conceived to promote the integration between traditional music theory and modern music theory from a diachronic perspective What is relevant to strengthen the unity of the nation and the world in basic music theory from a synchronic perspective, and to pay attention to the connotation of technology and culture in music theory teaching. But also to strengthen the scientific and logical concept in music theory textbooks.

title: I would be better off dead: investigating suicidal ideation in people with epilepsy

description: Abstract Background It is known that the risk of suicidal behavior in adult people with epilepsy (PWEs) is high. However, the associated clinical and psychosocial factors are still being discussed. Objective To assess the risk of suicide in PWEs and relate it to resilience and quality of life (QoL) as well as with clinical variables. Methods The item “I’d be better off dead” of the Neurological Disorders Depression Inventory for Epilepsy (NDDI-E) was related to the resilience scale, clinical aspects, the presence of depression, and the Quality of Life in Epilepsy Inventory (QOLIE-31) scores of PWEs, with a p &lt; 0.05. Results A total of 271 PWEs were assessed, 50.6% were female, with a mean age of 46.6 (± 15.8) years, and a mean age at 1st seizure of 24.1 (± 18.5) years. Risk for suicide occurred in 50 (19.3%) cases. In multiple logistic regression, the factors that explain the risk of suicide were female sex, depression, and lower scores on the QOLIE-31 and on the resilience scale. In the classification and regression trees, the order of importance of the variables was depression &gt; resilience &gt; age &gt; QoL &gt; age at 1st seizure. Conclusion The risk of suicide was high, and it was associated with demographic aspects, clinical variables, QoL, and resilience. A higher risk of suicide was associated with lower resilience regardless of the presence or absence of depression. In the presence of depression, a higher risk of suicide was associated with the early onset of epilepsy. In the absence of depression, the risk of suicide was associated with low QoL in young adults.

title: Effect of feeding frequency and water salinization on early development of Pyrrhulina brevis, an Amazonian ornamental fish

description: ABSTRACT Pyrrhulina brevis is an endemic fish from the Amazon basin that is valued in the ornamental fish market. In larviculture, fish are very sensitive to stressors and have a high mortality rate. Salinized water may provide more energy to overcome stress and feeding frequency is an important strategy to improve productive performance. Therefore, the aim of this study was to evaluate the best feeding frequency and the best level of water salinization for larval development of P. brevis. A total of 360 post-larvae of P. brevis (5.26 ± 1.65 mg, 5.57 ± 0.68 mm) were randomly distributed in 36 aquariums (1 L) in a 3x4 factorial scheme, to evaluate three concentrations of salt in water (0, 1 and 2 g L-1) and four feeding frequencies (once, twice, three and four times a day). We offered 150 Artemia nauplii per day and per post-larvae during 15 days. The fish kept at 1 g L-1 salinized water, and those fed 3 and 4 times a day presented significantly greater final length and weight, weight gain, and specific growth rate for length and weight. An interaction between salinized water and feeding frequency was observed for survival rate. We conclude that, during the initial rearing phase of P. brevis, feeding frequency of three times a day and salinized water at 1 g L-1 is recommended.

title: Feasibility of telemedicine for patients with parkinsonism in the Brazilian public health system

description: Abstract Background Telemedicine for patients with parkinsonism is feasible, cost-effective and satisfactory. However, the feasibility of this modality of care for this subpopulation is not known in real-life scenarios of developing countries like Brazil. Objective To evaluate the feasibility of telemedicine for patients with parkinsonism in a developing country. Methods A cross-sectional study with patients with parkinsonism treated in the Brazilian public healthcare system. We included 130 patients, who were contacted by telephone; those who could be reached underwent a structured interview for data collection. The primary outcomes were the feasibility of teleconsultations and video consultations, but we also performed a logistic regression regarding the feasibility of a video consultation and associated factors. Results Telemedicine was feasible and accepted by 69 (53.08%) patients regarding teleconsultations and by 50 (38.5%) patients regarding video consultations. Tele-consultations were feasible for 80.2%, and video consultations were feasible for 58.1% of the patients reachable through telephone calls. Having a higher family income was positively correlated with the feasibility for a video consultation while a negative association was observed regarding being married or in a stable union and having a low level of schooling. Conclusions A significant proportion of patients with parkinsonism in a developing country are unreachable, unwilling, or unable to participate in telemedicine. Among the reachable patients, feasibility is higher but still lower than what is reported in studies in developed countries. Family income, level of schooling, and marital status were associated with the feasibility of video consultations.

title: Dental and composite resin discoloration induced by different hydraulic calcium silicate-based cements: two-year in vitro assessment

description: Abstract Few long-term studies assess the discoloration induced by hydraulic calcium silicate-based cement on dental structures. In addition, as far as we know, no long-term study has assessed the discoloration induced by these cement on composite resin. Objective This in vitro study aimed to assess, during a period of two years, the discoloration potential of different hydraulic calcium silicate-based cements (hCSCs) on the enamel/dentin structure and composite resin restoration. Methodology A total of 40 enamel/dentin discs were obtained from bovine incisors, and 40 composite resin discs (10 mm in diameter × 2 mm thick) were fabricated. A 0.8 mm-deep cavity was made in the center of each disc and filled with the following hCSCs (n=10): Original MTA (Angelus); MTA Repair HP (Angelus); NeoMTA Plus (Avalon); and Biodentine (Septodont). An initial color measurement was performed (T0 - baseline). After 7, 15, 30, 45, 90, 300 days, and two years, new color measurements were performed to determine the color (ΔE00), lightness (ΔL’), chroma (ΔC’), hue differences (ΔH’), and whiteness index (WID). Results For enamel/dentin, the ΔE00 was significant among groups and periods (p&lt;0.05). NeoMTA Plus had the greatest ΔE00. The NeoMTA Plus group had the greatest ΔE00 after two years for composite resin. Significant reduction in lightness was observed for all groups after two years (p&lt;0.05). The most significant WID values were observed after 30 days for Biodentine (enamel/dentin) and MTA Repair HP groups (composite resin) (p&lt;0.05). Conclusions The hCSCs changed the colorimetric behavior of both substrates, leading to greater darkening over time. The Bi2O3 in the Original MTA seems relevant in the short periods of color change assessment.

title: Catquest-9SF questionnaire: validation of the Portuguese version using the Rasch analysis

description: ABSTRACT Purpose: The aim of this study was to validate the Portuguese version of Catquest-9SF through its application in a native Brazilian population with cataracts and to determine the correlation of the questionnaire scores with preoperative visual acuity. Methods: A prospective study was conducted to validate the Catquest-9SF questionnaire, which was translated and back-translated, generating a final version in Portuguese. A total of 120 Brazilian patients awaiting cataract surgery were recruited to answer the questionnaire and to document their preoperative data and visual acuity. The Rasch analysis was used to assess the instrument’s psychometric properties. Results: The Portuguese version of Catquest-9SF demonstrated an acceptable adjustment of the items (item fit statistics ranging from 0.7 to 1.3), unidimensionality (principal component analysis), and good organization in the item response categories (thresholds of the categories: -2.79, 0.57, and 2.22, respectively). The questionnaire contains items with stable relationships if considered at the same level of visual impairment in the comparison between the two groups (absence of differential item functioning). The separation of people (person separation index, 3.07) was adequate. The visual acuity in the logarithm of the minimum angle of resolution (logMAR) in the best eye with the best optical correction showed a statistically significant correlation with the Catquest-9SF logit score (r=0.282 and p=0.004). Conclusions: The Portuguese version of Catquest-9SF presents evidence of validity and reliability, in addition to being linguistically and culturally understandable for Portuguese-speaking patients born in Brazil. The questionnaire is easy to understand and quick to apply, as it could adequately estimate the subjective visual functioning in patients with cataracts. We found a significant correlation between visual acuity and the questionnaire score.

title: Can the timed up and go test be used as a predictor of muscle strength in older adults?

description: ABSTRACT This study analyzed the timed up and go test (TUG) as a tool to evaluate muscle strength in community-dwelling older people. As a methodology, an observational, cross-sectional and analytical study was conducted. Data from 442 older people were analyzed, both women (71.7%) and men (28.3%). Ages ranged from 62- 104 years, with a mean of 80.85 (±8.047) years. TUG was used as a tool to evaluate muscle strength. Comparison and correlation analyses were performed to compare performance between the TUG and the chair stand test (CST) and between TUG and handgrip strength (HGS). Analysis of agreement between the diagnosis of low physical performance on TUG and the diagnosis of muscle weakness on CST and HGS was also performed. The predictive values were estimated using the receiver operating characteristic curve. The analyses showed a moderate direct proportional correlation between TUG and CST performance and low inversely proportional correlations between TUG and HGS performance and between CST and HGS (p&lt;0.001). In the accuracy analyses, it was observed that TUG test could predict muscle strength in CST (S 34.4%; PPV 91.5%; NPV 26.1%; AUC=0.779; 95%CI 0.724-0.835; p&lt;0.001) and handgrip dynamometry (S 44.2%; PPV 77.4%; NPV 67.2%; AUC=0.652; 95%CI 0.599-0.705; p&lt;0.001). The Timed Up and Go test was able to satisfactorily indicate individuals with normal muscle strength in CST.

title: Accuracy of DRIS and CND methods and nutrient sufficiency ranges for soybean crops in the Northeast of Brazil

description: ABSTRACT. This study aimed to evaluate the nutrition of commercial soybean crops in an agricultural frontier region using the diagnosis and recommendation integrated system (DRIS) and compositional nutrient diagnosis (CND) methods, as well as identify sufficiency ranges. The study was performed by collecting leaf samples (third trifoliate leaf without petiole) at flowering from commercial soybean crops in the states of Piauí and Maranhão, Brazil, and evaluating the crop yield by analyzing macro- and micronutrients in the plant tissue of 98 samples. The DRIS and CND methods were applied based on the cataloged data, followed by the generation of norms, analysis of relationships between yield and nutrients (selecting high-yield crops by the cumulative function of the data), generation of sufficiency ranges, and comparison of methods. The relationships obtained by the DRIS and CND indices with the yield and nutrients were significant, indicating that both methods can be employed for the evaluation of leaf nutrients in soybean. The sufficiency ranges from the DRIS and CND methods presented superior nutrient ranges in relation to the values proposed in the literature for macronutrients, except for nitrogen, and greater range amplitudes for micronutrients.
