Abstract Purpose: The digital mindset can be defined as a set of individual behaviors related to the degree of adherence to digital transformations. After reviewing the literature on the subject, this research’s objective was to answer the following question: “Is it possible to measure the digital mindset of employees through a scale designed for the context of Brazilian organizations?”. Originality/value: The digitization of organizations has become the center of business transformation. However, one of the often-overlooked factors in the transition process is developed at the micro-organizational level. Collaborators vary in interest, knowledge, and ability to innovate. A measure to identify individual digital mindset profiles would be essential to guide the planning and development of a digital learning culture mindset. Still, such a tool was not yet found in the Brazilian literature. Design/methodology/approach: A multidimensional digital mindset construct was proposed based on the literature on cognitive structures and digital transformation mindset. Items were prepared to measure the degree of maturity of the construct, described through three digital profiles (open mind, transformer, and entrepreneur) and an analog profile. The scale was submitted to 574 professionals from Brazilian companies for exploratory factor analysis. Findings: The digital mindset scale showed signs of validity, confirming, in the present sample, the mindset dimensions related to the digital environment (Cronbach’s alphas between 0.85 and 0.62).

Resumo Objetivo: O mindset digital pode ser definido como um conjunto de comportamentos individuais relacionados ao grau de aderência às transformações digitais. Nesse contexto, o objetivo da presente pesquisa foi, após revisão de literatura sobre o tema, responder à seguinte questão: “É possível mensurar o mindset digital de profissionais por meio de uma escala elaborada para o contexto das organizações brasileiras?”. Originalidade/valor: A digitalização das organizações passou a ser o centro da transformação dos negócios. No entanto, um dos fatores muitas vezes negligenciado no processo de transição é o desenvolvimento no nível micro-organizacional. Os profissionais variam no nível de interesse, no conhecimento e na capacidade de inovar. Para guiar o planejamento e desenvolvimento de uma cultura de aprendizagem digital, uma medida para identificar os perfis individuais de mindset digital seria essencial, mas tal ferramenta ainda não era encontrada na literatura brasileira. Design/metodologia/abordagem: A partir da literatura sobre estruturas cognitivas e a transformação digital, foi proposto um construto multidimensional de mindset digital. Elaboraram-se itens para a mensuração do grau de maturidade do construto, descrito por meio de três perfis digitais (open mind, transformador e empreendedor) e um analógico. A escala foi submetida a 574 profissionais de empresas brasileiras para análise fatorial exploratória. Resultados: A escala de mindset digital apresentou bons indícios de validade, sendo confirmadas, na presente amostra, as dimensões de mindset relacionadas ao meio digital (alfas de Cronbach entre 0,85 e 0,62).

Abstract Objective To assess the potential relationship of clinical status upon admission and distance traveled from geographical health district in women with gestational trophoblastic disease (GTD). Methods This is a cross-sectional study including women with GTD from the 17 health districts from the São Paulo state (I–XVII), Brazil, referred to the Botucatu Trophoblastic Disease Center (specialized center, district VI), between 1990 and 2018. At admission, hydatidiform mole was assessed according to the risk score system of Berkowitz et al. Gestational trophoblastic neoplasia was evaluated using the International Federation of Gynecology and Obstetrics / World Health Organization (FIGO/WHO) staging/risk score. Data on demographics, clinical status and distance traveled were collected. Multiple regression analyses were performed. Results This study included 366 women (335 hydatidiform mole, 31 gestational trophoblastic neoplasia). The clinical status at admission and distance traveled significantly differed between the specialized center district and other districts. Patients referred from health districts IX (β = 2.38 [0.87–3.88], p = 0.002) and XVI (β = 0.78 [0.02–1.55], p = 0.045) had higher hydatidiform mole scores than those from the specialized center district. Gestational trophoblastic neoplasia patients from district XVI showed a 3.32 increase in FIGO risk scores compared with those from the specialized center area (β = 3.32, 95% CI = 0.78–5.87, p = 0.010). Distance traveled by patients from districts IX (200km) and XVI (203.5km) was significantly longer than that traveled by patients from the specialized center district (76km). Conclusion Patients from health districts outside the specialized center area had higher risk scores for both hydatidiform mole and gestational trophoblastic neoplasia at admission. Long distances (>80 km) seemed to adversely influence gestational trophoblastic disease clinical status at admission, indicating barriers to accessing specialized centers.

Resumo Objetivo Avaliar a possível relação entre estado clínico na apresentação e distância percorrida a partir do distrito de saúde em mulheres com doença trofoblástica gestacional. Métodos Estudo transversal incluindo mulheres com doença trofoblástica gestacional dos 17 distritos de saúde do estado de São Paulo (I–XVII), Brasil, encaminhadas ao Centro de Doenças Trofoblásticas de Botucatu (distrito VI), entre 1990 e 2018. Na admissão, avaliaram-se mola hidatiforme pelo sistema de pontuação de risco de Berkowitz et al. e neoplasia trofoblástica gestacional pelo escore de risco/estadiamento Federação Internacional de Ginecologia e Obstetrícia / Organização Mundial da Saúde (FIGO/OMS). Coletaram-se dados demográficos, clínicos e distância percorrida e análises de regressão múltipla foram realizadas. Resultados Este estudo incluiu 366 mulheres (335 mola hidatiforme, 31 neoplasia trofoblástica gestacional). O estado clínico na apresentação e distância percorrida diferiram significativamente entre o centro especializado e demais distritos. Nas pacientes encaminhadas pelos distritos IX (β = 2,38 [0,87–3,88], p = 0,002) e XVI (β = 0,78 [0,02–1,55], p = 0,045), os escores de mola hidatiforme foram maiores que no centro especializado. As pacientes com neoplasia trofoblástica gestacional do distrito XVI apresentaram escores FIGO 3,32 vezes maior que no centro especializado (β = 3,32, 95% CI = 0,78–5,87, p = 0,010). A distância percorrida pelas pacientes dos distritos IX (200km) e XVI (203,5km) foi significativamente maior do que a percorrida pelas pacientes do centro especializado (76km). Conclusão Pacientes de distritos de saúde fora da cobertura do centro especializado apresentaram escores de risco mais alto para mola hidatiforme e para neoplasia trofoblástica gestacional na admissão. Longas distâncias (>80 km) pareceram influenciar negativamente o estado clínico da doença trofoblástica gestacional na apresentação, indicando barreiras no acesso a centros especializados.

Abstract The aim of this study was to verify the effect of pinch size on skinfold thickness measurement and the consequent interference in the estimation and classification of body adiposity components. Cross-sectional and quantitative study carried out with a sample of 29 subjects recruited from a university in the city of Fortaleza, Ceará, Brazil. Four measurement steps were performed at each site of the eight chosen skinfolds. The first step was performed with a subjective-landmark and the three subsequent steps with fixed-landmarks defined with an expanding secondary line at 2 cm intervals. Body adiposity components were determined from the skinfold thickness measured at each landmark. Repeated measures ANOVA and Bland-Altman agreement analysis were applied. The subjective-landmark was chosen as the dependent variable. The 6 cm-landmark showed similarity and statistical agreement with the subjective-landmark for all skinfolds except the thigh, and with the sums of five and eight skinfolds. All fixed-landmarks showed agreement below the cut-off point for the percentile classification of subcutaneous adiposity and normative relative body fat. Variation in pinch size is an important source of TEM that can affect the reproducibility of skinfold thickness measurements and interfere in the estimation and classification of the molecular and tissue component of body adiposity.

Resumo O objetivo deste estudo foi verificar o efeito do tamanho da pinça na medida de espessura das dobras cutâneas e a consequente interferência na estimativa e classificação dos componentes da adiposidade corporal. Estudo transversal e quantitativo realizado com amostra de 29 sujeitos recrutados em uma universidade da cidade de Fortaleza, Ceará, Brasil. Quatro etapas de medição foram realizadas em cada sítio das oito dobras cutâneas escolhidas. A primeira etapa foi realizada com um marco subjetivo e as três etapas subsequentes com marcos fixos definidos com uma linha secundária expansiva em intervalos de 2 cm. Os componentes da adiposidade corporal foram determinados a partir da espessura de dobras cutâneas mensuradas em cada marco. ANOVA de medidas repetidas e análise de concordância de Bland-Altman foram aplicadas. O marco subjetivo foi escolhido como variável dependente. O marco de 6 cm apresentou semelhança e concordância estatística com o marco subjetivo para todas as dobras cutâneas, exceto a coxa, e com as somas de cinco e oito espessuras de dobras cutâneas. Todos os marcos fixos mostraram concordância abaixo do ponto de corte para a classificação percentílica de adiposidade subcutânea e gordura corporal relativa normativa. A variação no tamanho da pinça é uma importante fonte de ETM que pode afetar a reprodutibilidade de medida de espessura das dobras cutâneas e interferir na confiabilidade da estimativa e classificação do componente molecular e tecidual da adiposidade corporal.

Abstract The objective of this study was to evaluate the production, fat and fatty acids of milk as well as the diameter, classification and quantity of the milk fat globules (MFG) of goats consuming a diet with 15% of crude glycerin. Twelve multiparous Saanen goats weighing 40 ± 6 kg and 90 ± 5 days of lactation were used. The experimental design was completely randomized with two treatments (0 and 15% inclusion of glycerin). In this way, each milk sample is classified according to the percentage of milk fat globules that were included in these three size categories. For the variables milk production, fat, diameter, medium and large fat globules and amount of globules showed a significant effect of the inclusion of glycerin in the diet (p < 0.05). Fifteen fatty acids were found, mostly saturated. For caprylic, palmitic, and linoleic fatty acids, there was no significant influence of the inclusion of glycerin (p > 0.05). Can recommend the use of 15% double-distilled glycerin in the feeding of lactating goats increased milk production, the amount of fat, increased the size of the milk fat globule. Regarding the saturated and polyunsaturated fatty acids, they kept the level of 15% of glycerin.

Abstract The objective of this research was to evaluate the production, milk quality, consumption and financial analysis of milk from goats consuming diets with different levels of double-distilled glycerin. Twelve multiparous Saanen goats, weighing 40 ± 6 kg and 30 ± 5 days of lactation, kept in a confinement system for 60 days were used. The goats were randomly distributed in a Latin square (4 x 4), according to the levels of double-distilled glycerin. The ingredients used were tifton hay, ground corn grain, soybean meal, vitamin/mineral supplement, urea, and double-distilled glycerin levels (0, 6, 12 and 18%) to replace corn in the diets. The milk fat of goats fed with double-distilled glycerin in the diet showed a decreasing linear regressive effect (P = 0.001). Dry matter intake showed a quadratic regressive effect (P = 0.033). Evaluating the total cost of each diet, it was observed that the level containing 0% glycerin was the diet with the lowest cost per kilogram. The use of double-distilled glycerin in the feeding of dairy goats can be recommended up to the level of 18% of corn replacement without harming milk production, however, it is necessary to verify the economic viability, considering that there will be losses in the quality of the milk produced.

Abstract The study aimed to evaluate tannic acid's influence on lactating cows' diets on milk production and lipid composition. Five crossbred cows (Holstein x Zebu), distributed in a 5 × 5 Latin square, were used to evaluate the effect of increasing tannic acid (hydrolyzable tannin). The diets were composed of 35 kg of corn silage as bulking and 6.38 kg of concentrate. The treatments consisted of increasing levels of tannic acid added to diets (0%, 1.3%, 2.6%, 3.9% and 5.2%). It was observed a decreasing linear effect (P<0.05) of the inclusion of tannic acid in the concentration of saturated butyric fatty acids (C4:0) presenting a mean of (2.99), and quadratic effect in the concentration of saturated fatty acids lauric (C12:0) presenting mean (26.74). The addition of tannic acid had effects on saturated fatty acids, decreasing the concentrations of butyric acid and increasing the concentrations of lauric acid. Atherogenicity and thrombogenicity rates reveal the potential for the prevention of coronary heart disease. However, the observed changes do not compromise the milk's chemical composition and nutritional quality,the y nutritional quality of the milk, presenting possibilities of human health benefits, thus enabling the aggregation of value for these products.

Abstract The study aimed to evaluate the effect of adding tannic acid to the diet on the milk quality of cows. The five primiparous crossbred cows (Holstein x Zebu) were used, with about four years old, the average body weight of 420 ± 30 kg, 100 days of lactation initial average production of 18 ± 4 kg of milk/cow/day. The treatments consisted of increasing tannic acid (0; 1.3; 2.6; 3.9 and 5.2%) to replace corn bran in the diet, based on dry matter. The sensory attributes of odor had a significant effect (P < 0.05) of the inclusion of tannic acid in the diet. The odor attributes showed a lower average for the control treatment, and these attributes also showed orthogonal contrast, except the characteristic cow, that is, the control group differed from the treatments as the tannin was introduced, the attribute value became higher compared to the control group. The inclusion of 5.2% tannic acid in dairy cows’ diet promoted a slight variation in the taste of milk. However, it did not alter the quality or acceptance of this milk by consumers.

Abstract The objective of this study was to evaluate the effects of replacing corn by double-distilled glycerin, a co-product of the biodiesel industry, on goat curd cheese in terms of physical-chemical, microbiological and sensory aspects. Twelve multiparas Saanen goats weighing 47.07 ± 2.41 kg and at 90 ± 5 days of lactation. The experimental design was completely randomized with two treatments (0 and 15% inclusion of glycerin). The physicochemical parameters analyzed were: fat (%), non-fat solids (%), protein (%), lactose (%), salts (%), relative density at 15/15 °C (gmL-1), index cryoscopic (°C), electrical conductivity (mScm-1), pH and acidity. The milk from each treatment was used to make the rennet cheese. The fat had a significant effect (P < 0.05) with inclusion of glycerin in the diet. The physicochemical characteristics of the cheese were influenced (P < 0.05) by feeding up to 15% of glycerin. Regarding sensory attributes, only firmness was influenced (P < 0.05) by the inclusion of glycerin in the diet of dairy goats. Bidistilled glycerin, when inserted in the diet of dairy goats at a level of 15%, causes a reduction in the lipid content of milk and cheese, consequently affecting the cheese yield, and the parameter of firmness in the sensory of the evaluated cheeses.

Resumo Objetivo A pré-eclâmpsia (PE) é uma síndrome específica da gravidez caracterizada por níveis anormais de citocinas e fatores angiogênicos, que desempenham um papel no desenvolvimento da doença. Este estudo avaliou se os marcadores imunológicos estão associados à idade gestacional e à gravidade da doença em mulheres com pré-eclâmpsia. Métodos Noventa e cinco mulheres que desenvolveram PE foram estratificadas pela idade gestacional em PE pré-termo (< 37 semanas) e PE a termo (≥ 37 semanas de gestação) e comparadas quanto à gravidade da doença, bem como à concentração plasmática de fatores angiogênicos e citocinas. As concentrações de fator de crescimento placentário (PlGF), fator de crescimento endotelial vascular (VEGF), tirosina quinase solúvel semelhante a Fms (sFlt-1) e endoglina solúvel (sEng), bem como as citocinas, fator de necrose tumoral alfa (TNF- α) e interleucina 10 (IL-10), foram determinados porensaio de imunoabsorção enzimática (ELISA, na sigla em inglês). Resultados A comparação entre os grupos com pré-eclâmpsia mostrou maior porcentagem de casos graves em PE pré-termo (82,1%) do que em PE a termo (35,9%). Da mesma forma, as concentrações de TNF-α, sFlt-1 e sEng, bem como as razões TNF-α/IL-10 e sFlt-1/PlGF foram significativamente maiores no grupo de PE pré-termo. Em contraste, as concentrações de PlGF, VEGF e IL-10 foram significativamente menores em mulheres com PE pré-termo. Correlações negativas entre TNF-α e IL-10 (r = 0.5232) e entre PlGF e sFlt1 (r = 0.4158) foram detectadas no grupo de PE pré-termo. Conclusão Em gestantes com PE pré-termo, ocorre um desequilíbrio entre os marcadores imunológicos, com predomínio de fatores antiangiogênicos e TNF-α, associados a desfechos clínicos maternos adversos.

Abstract Objective Preeclampsia (PE) is a pregnancy-specific syndrome characterized by abnormal levels of cytokines and angiogenic factors, playing a role in the disease development. The present study evaluated whether immunological markers are associated with the gestational age and with the disease severity in preeclamptic women. Methods Ninety-five women who developed PE were stratified for gestational age as preterm PE (< 37 weeks) and term PE (≥ 37 weeks of gestation) and compared for disease severity as well as plasma concentration of angiogenic factors and cytokines. The concentrations of placental growth factor (PlGF), vascular endothelial growth factor (VEGF), Fms-like soluble tyrosine kinase (sFlt-1) and soluble endoglin (sEng), as well as the cytokines, tumor necrosis factor-α (TNF-α) and interleukin 10 (IL-10), were determined by enzyme-linked immunosorbent assay (ELISA). Results The comparison between preeclamptic groups showed a higher percentage of severe cases in preterm PE (82.1%) than in term PE (35.9%). Similarly, the concentrations of TNF-α, sFlt-1, and sEng, as well as TNF-α/IL-10 and sFlt-1/PlGF ratios were significantly higher in the preterm PE group. In contrast, concentrations of PlGF, VEGF, and IL-10 were significantly lower in women with preterm PE. Negative correlations between TNF-α and IL-10 (r = 0.5232) and between PlGF and sFlt1 (r = 0.4158) were detected in the preterm PE. Conclusion In pregnant women with preterm PE, there is an imbalance between immunological markers, with the predominance of anti-angiogenic factors and TNF-α, associated with adverse maternal clinical outcomes.

Abstract The objective of this study was to evaluate the effects of replacing corn with bidistilled glycerin from the biodiesel industry on the physicochemical, microbiological, and sensory quality of milk and goat cheese. Twelve Saanen multiparous goats weighing 40 ± 6 kg and 30 ± 5 days of lactation were used. The physicochemical parameters analyzed were: fat (%), non-fat solids (%), protein (%), lactose (%), salts (%), relative density at 15/15 °C (gmL-1), index cryoscopic (°C), electrical conductivity (mScm-1), pH and acidity. The milk from each treatment was used to make the rennet cheese. The physicochemical variables: pH, lipids, ESD, and cheese yield had a significant effect (P < 0.05) for the increasing use of bidistilled glycerin in the goat feeding. The pH, acidity, EST, ESD, and yield variables presented linear regressive effect and lipids quadratic regressive effect. The softness sensory attribute had a significant effect (P < 0.05) for the increasing levels of bidistilled glycerin in the goat diet; the softness decreased as the glycerin level increased. Bi-distilled glycerin, when inserted in the diets of dairy goats at increasing levels, promotes a reduction in the lipid content of milk, consequently affecting the cheese yield and the sensory softness parameter.
