RESUMO

RESEARCH QUESTION: In women with singleton pregnancies conceived after assisted reproductive technologies, does the in vitro fertilization with oocyte donation (IVF-OD) affect the perinatal and maternal outcomes compared to autologous in vitro fertilization (IVF-AO)? DESIGN: Systematic review and meta-analysis of studies comparing perinatal and maternal outcomes in singleton pregnancies resulting from IVF-OD versus IVF-AO. An electronic literature search in Pubmed, MEDLINE, and Cochrane database was performed. The main outcome measures were hypertensive disorders in pregnancy, preeclampsia, severe preeclampsia, pregnancy-induced hypertension, preterm birth, early preterm birth, low birth weight, and very low birth weight. RESULTS: Twenty-three studies were included. IVF-OD is associated with a higher risk of hypertensive disorders in pregnancy (OR 2.63, 2.17-3.18), preeclampsia (OR 2.64; 2.29-3.04), severe preeclampsia (OR 3.22; 2.30-4.49), pregnancy-induced hypertension (OR 2.16; 1.79-2.62), preterm birth (OR 1.57; 1.33-1.86), early preterm birth (OR 1.80; 1.51-2.15), low birth weight (OR 1.25, 1.20-1.30), very low birth weight (OR 1.37, 1.22-1.54), gestational diabetes (OR 1.27; 1.03-1.56), and cesarean section (OR 2.28; 2.14-2.42). There was no significant difference in the risk of preterm birth or low birth weight when adjusted for preeclampsia. CONCLUSIONS: IVF-OD patients should be considered an independent risk factor for some adverse perinatal outcomes, mainly hypertensive disorders in pregnancy, preeclampsia, and severe preeclampsia. Immunological and hormonal aspects may be involved in these results, and further research focusing in the etiopathogenesis of these pathologies are needed.

RESUMO

We report accurate optical measurements of tubulin polarizability in aqueous suspensions. We determined the dependence of polarizability on tubulin concentration and on the suspension's pH, providing benchmark numbers for quantifying the optical response of this protein in various artificial and cellular environments. We compare our measurement data with a few estimates found in the previous literature and also with our simplified model estimations.

RESUMO

INTRODUCTION: Liver fibrosis and cirrhosis are late complications in Fontan palliation. Liver biopsy is the gold standard. The goal of this study is to correlate transjugular liver biopsy (TJLB) in the setting of Fontan palliation with noninvasive testing and hemodynamics. METHODS: Between August 2014 and July 2017, 49 Fontan patients underwent TJLB. All the patients had hemodynamic evaluation, 28 patients had MRE (magnetic resonance elastography) and 40 patients had cardiopulmonary exercise test. Histologic liver fibrosis was quantitated using traditional histologic scoring systems and a modified Ishak congestive hepatic fibrosis score. RESULTS: Median age 17.8 years, median time since Fontan 15.2 years. Primary diagnosis and Fontan type were variables, but predominantly LV morphology (30/49), lateral tunnel Fontan (29/49), originally fenestrated (37/49), and 11/49 had a pacemaker. Histologic fibrosis correlated with MRE (R = 0.62, P ≤ .001). Histologic fibrosis and MRE correlated with Fontan pressure (R = 0.38, P = .008 & R = 0.59, P ≤ .001). Morphology of the single ventricle did not correlate with liver fibrosis. The presence of a fenestration resulted in a higher cardiac index (P = .026) but did not resulted in lower liver fibrosis (P = .64). CONCLUSION: Noninvasive tests, such as MRE, may be suitable for longitudinal follow-up in patients with single ventricle physiology. Our data suggest that there is reasonable correlation of MRE liver stiffness with biopsy scoring systems and Fontan pressures. We demonstrated the feasibility of TJLB in the setting of Fontan palliation and demonstrated its correlation with noninvasive measures particularly MRE. We recommend selective use of TJLB when MRE score is >5 KPa or when there are other clinical signs of cirrhosis.

RESUMO

La presente investigación tiene por objeto comparar las actitudes hacia el ahorro, consumo y endeudamiento en titulados de una universidad pública del sur de Chile, a partir de su género, nivel socioeconómico y facultad de procedencia. Cuenta con un diseño cuantitativo, no experimental, ex post facto, de alcance descriptivo-correlacional y de tipo transversal. Se administraron la Escala de Actitudes hacia el Endeudamiento, la Escala de Actitudes hacia el Ahorro, la Escala de Actitudes hacia la Compra y la Escala de Evaluación del Nivel Socioeconómico ESOMAR. Además, se aplicó un cuestionario de preguntas de clasificación sociodemográfica, que fue respondido por 120 titulados universitarios de una universidad pública del sur de Chile contactados mediante el método bola de nieve. Se realizaron análisis descriptivos, pruebas de comparación de medias y medianas para dos muestras independientes para las comparaciones según género, nivel socioeconómico y facultad de procedencia (pruebas t para muestras independientes y pruebas U de Mann-Whitney),y pruebas de correlación r de Pearson para identificar posibles asociaciones entre las distintas escalas y subescalas. Los resultados permiten concluir un perfil esperable en cuanto a actitudes hacia el ahorro, endeudamiento y la compra, en titulados universitarios. En relación a las comparaciones, si bien se encontraron algunas diferencias significativas en cuanto a género y nivel socioeconómico de los participantes, resultaron más bien bajas. Finalmente, se hallaron asociaciones entre actitudes hacia el ahorro con austeridad y con racionalidad en la compra. También se encontraron asociaciones entre compulsividad en la compra con austeridad (inversamente) y con impulsividad en la compra, lo que apunta a una coherencia teórica de los constructos y sus dimensiones. Limitaciones del estudio incluyen el uso de medidas de autorreporte, lo que restringe la extrapolación de resultados a contextos fuera del presente estudio. Otra limitación corresponde al método de muestreo utilizado (bola de nieve) y tamaño muestral, lo que no permitiría generalizar los resultados a la población. A partir de los hallazgos y limitaciones, se realizan sugerencias para futuras investigaciones en alfabetización económica.


Since the decade of 1970 onward in Chile, there has been a substantial change in terms of economic behaviour, which stems mainly from the installation of a neoliberal socioeconomic model. The profound consequences of this change for the Chilean society can be seen to this day, 40 years later, and these consequences include: broader access to goods and services for segments of the population that were previously excluded and/or that were a privilege of the economic elites; the assignation of new meanings to the concepts of purchase; and saving and indebtedness. These are all key concepts for the development and comprehension the neoliberal model. Complementary, the study of university graduates' behaviour is especially relevant in this area, considering that higher education is often thought to play a substantial role in social mobility. In the Chilean context, the transformations of the educational system have favoured the expansion of the admission numbers up to the point that seven of ten Chileans that pursue a graduate degree are the first members of their family to reach this educational level. Considering the above, the present study aims to compare attitudes towards purchase, saving and indebtedness in graduates from a university in southern Chile, by gender, socioeconomic level and faculty. The study follows a quantitative, cross-sectional, non-experimental, ex-post-facto design, with a descriptive-correlational scope. A questionnaire was completed by 120 participants contacted via snowball method. The questionnaire included: the Attitudes toward Indebtedness Scale; Attitudes toward Saving Scale; and Attitudes toward Purchase Scale, a scale that evaluates the participants' socioeconomic level and other sociodemographic information to help describe the sample. Descriptive analyses were carried out, along with mean and median comparisons for gender, socioeconomic level and faculty (t tests for independent samples and Mann-Whitney U tests). Finally, correlation tests with Pearson's r test were carried out to test associations between the scales and subscales. Results showed a profile that is desirable in university graduates in terms of attitudes towards saving, indebtedness and purchase, that is: favourable attitudes toward saving, austerity (a subscale of attitudes toward indebtedness) and rationality (a subscale of attitudes toward purchase), as well as negative attitudes toward hedonism (a subscale of attitudes toward indebtedness), and compulsivity and impulsivity (subscales of attitudes toward purchase). In terms of comparison, differences were found when comparing participants by gender in terms of attitudes toward compulsivity, and by their socioeconomic level by attitudes toward austerity in the indebtedness. Both these differences, although significant, were low when considering their effect size. No differences were found when comparing the faculty to which participants belonged in terms of attitudes toward saving, indebtedness and purchase. Finally, results showed associations between attitudes toward saving and austerity and with rationality, and between compulsivity and austerity (inversely) and with impulsivity. These results highlight the need to strengthen the attitudinal aspect in higher education environments where economic literacy is carried out, aiming to prepare students for their insertion into the workforce and their role as active citizens. Limitations of this study include the subjective self-report measurements used, which are susceptible to the effect of social desirability. This limitation hinders the extrapolation of the results in terms of attitudes into actual behaviour in the real world. Another limitation comes from the sampling method used (snowball) and sample size, which does not allow to generalize the results to the population. Drawing from both findings and limitations, suggestions for future research in the subject of economic literacy and related issues are outlined.

RESUMO

Abstract The objectives of this study were to examine the psychometric properties of the Multidimensional Life Satisfaction Scale in university students (MSLSS) (Huebner, 1998) in a sample of university students from northern, central and southern Chile, where indicators of reliability and construct validity were examined. Also, it seeks to describe the levels of life satisfaction of students and to examine differences between gender and between socioeconomic statuses. The study is quantitative with a cross-sectional descriptive-relational design. The Multidimensional Life Satisfaction Scale was applied to a sample of 306 university students in northern, central and southern Chile, as well as a questionnaire that collected sociodemographic variables. It was used confirmatory factor analysis to evaluate the model expected from the five factors of the 40-item version of the scale. The results showed the scale had adequate psychometric behavior in this type of population, where also high satisfaction levels in overall and specific domains were found, and group differences were found by gender but not by socioeconomic status.


Resumen Los objetivos de este estudio fueron evaluar las propiedades psicométricas de la Escala Multidimensional de Satisfacción con la Vida en Estudiantes (MSLSS) (Huebner, 1998) en una muestra de estudiantes universitarios de la zona norte, centro y sur de Chile, examinando indicadores de contabilidad y validez de constructo. Junto a esto, se buscó describir los niveles de satisfacción con la vida de los estudiantes y examinar diferencias por género y nivel socioeconómico. El estudio es cuantitativo con un diseño descriptivo relacional transversal. La Escala Multidimensional de Satisfacción con la Vida fue aplicada a una muestra intencionada de 306 estudiantes universitarios en el norte, centro y sur de Chile, al igual que un cuestionario que recogió variables sociodemográficas. Se utilizó el análisis factorial confirmatorio para evaluar el modelo esperado de cinco factores de la versión de 40 ítems de la escala. Los resultados demuestran que la escala tiene un comportamiento psicométrico adecuado para este tipo de población, también se encontraron altos niveles de satisfacción en los dominios generales y específicos, y diferencias en género, mas no en nivel socioeconómico.

RESUMO

Abstract This study assesses the relationship between food satisfaction and family satisfaction and their relationships to university student life satisfaction, while also exploring the moderating role of the place of student residence, student self-health perception and the importance students assign to food in relation to well-being. A survey was applied to a convenience sample of 269 university students. The questionnaire included: the Satisfaction with Life Scale, Satisfaction with Food-related Life, the family subscale of the Multidimensional Students' Life Satisfaction Scale and the first item of the Health-related Quality of Life Index. Having controlled for gender and socioeconomic status, it was found that a student's life satisfaction was significantly related to food satisfaction and, to a lesser extent, family satisfaction. Food satisfaction was positively and significantly related to family satisfaction. A moderating role of student residence was not found. Student health self-perception was found to moderate the relationship between family and life satisfaction, whereas the importance assigned to food in relation to well-being was found to moderate the relationship between food and student life satisfaction. These findings suggest that, in order to increase student life satisfaction, it is important to improve family satisfaction for those students who have a negative health self-perception. Likewise, improving food satisfaction is relevant for those students who gave low importance to food in regard to their well-being.


Resumen El objetivo de este estudio fue evaluar la relación entre la satisfacción con la alimentación y la satisfacción familiar, sus relaciones con la satisfacción con la vida de estudiantes universitarios y explorar el rol moderador del lugar donde el estudiante vive, su autopercepción de la salud y de la importancia asignada a la alimentación para el bienestar. Se aplicó una encuesta a una muestra por conveniencia de 269 estudiantes universitarios. El cuestionario incluyó la Escala de Satisfacción con la Vida, Satisfacción con la Alimentación, la subescala de Familia de la Escala Multidimensional de Satisfacción con la Vida de Estudiantes y el primer ítem del Índice de Calidad de Vida Relacionado con la Salud. Habiendo controlado por género y nivel socioeconómico, se encontró que la satisfacción con la vida del estudiante se relacionó significativamente con la satisfacción con la alimentación y, en menor medida, con su satisfacción familiar. La satisfacción con la alimentación se relacionó positiva y significativamente con la satisfacción familiar. No se encontró un rol moderador del lugar donde el estudiante vive. La autopercepción de salud del estudiante moderaría la relación entre la satisfacción con la vida y la familia, mientras la importancia asignada a la alimentación para el bienestar moderaría la relación entre la satisfacción con la vida y la alimentación. Estos resultados sugieren que para incrementar la satisfacción con la vida de los estudiantes, es importante mejorar la satisfacción con la familia en los estudiantes que tienen una mala autopercepción de salud, mientras que mejorar la satisfacción con la alimentación es relevante en los estudiantes que asignan baja importancia a la alimentación para su bienestar.

RESUMO

Abstract The Multidimensional Students' Life Satisfaction Scale is an instrument to assess life satisfaction in children and adolescents in five life domains. However, research on multidimensional life satisfaction in older students, such as those attending university, is still scarce. This paper undertook to evaluate the psychometric properties of the Multidimensional Students' Life Satisfaction Scale in a sample of university students from five state universities in Chile. The Multidimensional Students' Scale and Satisfaction with Life Scale were applied to 369 participants. Confirmatory factor analysis was used to evaluate the expected correlated five-factor model of the long version (40 items) and the abbreviated version (30 items) of the Multidimensional Students' Life Satisfaction Scale. The goodness-of-fit values obtained from confirmatory factor analysis revealed that the data fit better to the 30-items and five-factor structure than to the 40-item structure. The convergent, concurrent and discriminant validity of the 30-item version was demonstrated. The 30-item version of the Multidimensional Students' Life Satisfaction Scale may be a promis ing alternative to measure satisfaction in different life domains in university students, and a valuable tool for differential assessments that guide research and intervention on this population.


Resumen La Escala Multidimensional de Satisfacción con la Vida en Estudiantes mide la satisfacción con la vida en la niñez y adolescencia en cinco dominios de la vida. La investigación sobre satisfacción multidimensional con la vida es escasa en estudiantes de mayor edad, como aquellos que asisten a la Universidad. El objetivo de este estudio es evaluar las propiedades psicométricas de la Escala Multidimensional de Satisfacción con la Vida en Estudiantes en una muestra de estudiantes de cinco universidades estatales de Chile. La Escala Multidi mensional de Satisfacción con la Vida en Estudiantes y la Escala de Satisfacción con la Vida fueron respondidas por 369 participantes. Se utilizó el análisis factorial confirmatorio para evaluar el modelo esperado de cinco factores de las versiones larga (40 items) y abreviada (30 items) de la Escala Multidimensional de Satisfacción con la Vida en Estudiantes. Los val ores de bondad de ajuste obtenidos revelaron que los datos se ajustaron mejor a la escala de 30 items y a la estructura de cinco factores. La validez convergente, concurrente y discrimi nante de esta versión fue demostrada. La versión de 30 items de la Escala Multidimensional de Satisfacción con la Vida en Estudiantes puede constituir una alternativa prometedora para medir la satisfacción de estudiantes universitarios en distintos dominios de la vida, así como una herramienta valiosa para la evaluación diferencial que guie la investigación e intervención en esta población.

RESUMO

ABSTRACT This study aimed to characterize dieting and non-dieting university students by gender, Received 14 September 2016 based on their satisfaction with life and their food-related life, self-discrepancy, food behavior and health-related aspects. A non-probabilistic sample of 305 students from five Chilean state universities responded a questionnaire that included the Revised Restraint Scale, the Satisfaction with Life Scale, the Satisfaction with Food-related Life Scale, the Health-related Quality of Life Index, the Nutrition Interest Scale and the Self-Discrepancy Index. Sociodemographic characteristics, food behavior, and approximate weight and height were also enquired. Chronic dieters and non-dieters were distinguished according to the median score of the Revised Restraint Scale. 51.1% of women and 55.5% of men classified as chronic dieters, sharing characteristics such as nutrition concern, mental health problems, higher body mass index, and physical and economic self-discrepancy. Women dieters reported lower life satisfaction and satisfaction with food-related life, more health problems and health-related restriction of food, while men dieters showed higher social and emotional self-discrepancy.


RESUMEN El objetivo de este estudio fue caracterizar a estudiantes universitarios dietantes y no dietantes de distinto género, según su satisfacción con la vida y con la alimentación, discrepancia del yo, comportamiento alimentario y aspectos relacionados con la salud. Se aplicó un cuestionario a una muestra no probabilística de 305 estudiantes de cinco universidades estatales de Chile. El cuestionario incluyó la Escala Revisada de Restricción Alimentaria, la Escala de Satisfacción con la Vida, la Escala de Satisfacción con la Alimentación, el Índice de Calidad de Vida relativo a la Salud, la Escala de Interés por la Nutrición y la Escala de Discrepancia del Yo. Se consultaron características sociodemográficas, comportamiento alimentario y el peso y estatura aproximados. Con base en la mediana de la Escala Revisada de Restricción Alimentaria se distinguieron dietantes crónicos y no dietantes. El 51.1% de las mujeres y el 55.5% de los hombres fueron clasificados como dietantes crónicos, quienes comparten características como la preocupación por la nutrición, problemas de salud mental, mayor índice de masa corporal, y discrepancia del yo en los ámbitos físico y económico. Las mujeres dietantes estuvieron menos satisfechas con su vida y con su alimentación, reportaron más problemas de salud y superior restricción de alimentos por motivos de salud. Los hombres dietantes mostraron mayor discrepancia del yo en los ámbitos social y emocional.

RESUMO

The aims of this study were to test the relationships between food neophobia, satisfaction with food-related life and food technology neophobia, distinguishing consumer segments according to these variables and characterizing them according to willingness to purchase food produced with novel technologies. A survey was conducted with 372 university students (mean aged=20.4years, SD=2.4). The questionnaire included the Abbreviated version of the Food Technology Neophobia Scale (AFTNS), Satisfaction with Life Scale (SWLS), and a 6-item version of the Food Neophobia Scale (FNS). Using confirmatory factor analysis, it was confirmed that SWFL correlated inversely with FNS, whereas FNS correlated inversely with AFTNS. No relationship was found between SWFL and AFTNS. Two main segments were identified using cluster analysis; these segments differed according to gender and family size. Group 1 (57.8%) possessed higher AFTNS and FNS scores than Group 2 (28.5%). However, these groups did not differ in their SWFL scores. Group 1 was less willing to purchase foods produced with new technologies than Group 2. The AFTNS and the 6-item version of the FNS are suitable instruments to measure acceptance of foods produced using new technologies in South American developing countries. The AFTNS constitutes a parsimonious alternative for the international study of food technology neophobia.

RESUMO

In this paper we demonstrate the passive, material-based athermalization of all-fiber architectures by cascading multimode interference (MMI) devices. In-line thermal compensation is achieved by including a liquid-core multimode section of variable length that allows ensuring temperature-independent operation while preserving the inherent filter-like spectral response of the MMI devices. The design of the temperature compensation unit is straightforward and its fabrication is simple. The applicability of our approach is experimentally verified by fabricating a wavelength-locked MMI laser with sensitivity of only -0.1 pm/°C, which is at least one order of magnitude lower than that achieved with other fiber optics devices.

RESUMO

The aim of this study was to categorize university students based on their association between food neophobia and levels of subjective well-being, in general and in the food domain, and their perception of their family's eating habits. A survey was conducted among 372 university students from southern Chile. The questionnaire included the Food Neophobia Scale (FNS), Satisfaction with Life Scale (SWLS), Satisfaction with Food-related Life (SWFL), Health-related Quality of Life Index (HRQOL-4), and Family Eating Habits Questionnaire (FEHQ). Three student types were distinguished by cluster analysis: Group 1 (26.9%) had the highest scores on the FNS, SWLS and SWFL. Group 2 (40.8%) had a high score on the FNS but the lowest scores on the SWLS and SWFL. Group 3 (32.3%) had the lowest FNS score and high scores on the SWLS and SWFL. Group 2 stood out in having a low score on the FEHQ's component for cohesiveness of family eating. These results suggest that both neophobic and non-neophobic students have positive levels of satisfaction with life and food-related life, and that satisfaction among neophobic students is related to family eating patterns, especially cohesiveness in family eating.

RESUMO

OBJECTIVE: Neonatal coronary thrombosis is a rarely reported disorder, with variable outcomes described. This study assessed the feasibility and safety of an institutional protocol using tissue plasminogen activator (tPA) administration for the treatment of neonatal coronary artery thrombi. METHODS: They reviewed the outcome of three neonates with clinical evidence of myocardial infarction secondary to coronary thrombosis. All three underwent the tPA treatment protocol. RESULTS: The three described cases presented at 5 hours, 15 hours, and 10 days of life. The patients identified underwent the tPA protocol at least once. There was clinical evidence of improvement in coronary flow, as well as demonstration of increased left ventricular function and decreased mitral regurgitation. No major adverse events occurred. CONCLUSION: Thrombolytic therapy with this tPA protocol may be safe and effective in treating neonates with coronary thrombosis.

RESUMO

This study examined longitudinal measurement invariance in the Satisfaction with Food-related Life (SWFL) scale using follow-up data from university students. We examined this measure of the SWFL in different groups of students, separated by various characteristics. Through non-probabilistic longitudinal sampling, 114 university students (65.8% female, mean age: 22.5) completed the SWFL questionnaire three times, over intervals of approximately one year. Confirmatory factor analysis was used to examine longitudinal measurement invariance. Two types of analysis were conducted: first, a longitudinal invariance by time, and second, a multigroup longitudinal invariance by sex, age, socio-economic status and place of residence during the study period. Results showed that the 3-item version of the SWFL exhibited strong longitudinal invariance (equal factor loadings and equal indicator intercepts). Longitudinal multigroup invariance analysis also showed that the 3-item version of the SWFL displays strong invariance by socio-economic status and place of residence during the study period over time. Nevertheless, it was only possible to demonstrate equivalence of the longitudinal factor structure among students of both sexes, and among those older and younger than 22 years. Generally, these findings suggest that the SWFL scale has satisfactory psychometric properties for longitudinal measurement invariance in university students with similar characteristics as the students that participated in this research. It is also possible to suggest that satisfaction with food-related life is associated with sex and age.

Resumen: El objetivo fue categorizar a los estudiantes universitarios en base a la asociación entre la neofobia alimentaria y los niveles de bienestar subjetivo general (y específico del dominio alimentario), además de la percepción de los estudiantes, en relación con los hábitos alimentarios de la familia. Se realizó una encuesta entre 372 universitarios del sur de Chile. El cuestionario incluyó la Food Neophobia Scale (FNS), Satisfaction with Life Scale (SWLS), Satisfaction with Food-related Life (SWFL), Health-related Quality of Life Index (HRQOL-4) y Family Eating Habits Questionnaire (FEHQ). El análisis de clústeres distinguió tres tipos de universitarios: el grupo 1 (26,9%) obtuvo las puntuaciones más altas en la FNS, SWLS y SWFL. El grupo 2 (40,8%) tuvo una puntuación alta en la FNS, aunque con puntuaciones más bajas en la SWLS y SWFL. El grupo 3 (32,3%) tuvo la FNS más baja y puntuaciones altas en la SWLS y SWFL. El grupo 2 se destacó por tener una puntuación baja en el componente del FEHQ, referente a la cohesión de la alimentación familiar. Los resultados sugieren que estudiantes neofóbicos y no-neofóbicos tienen niveles positivos de satisfacción con la vida, y con la vida relacionada con la alimentación, y que la satisfacción entre estudiantes neofóbicos está relacionada con los patrones alimentarios de la familia, sobre todo con la cohesión de la alimentación familiar.


Resumo: Objetivou-se categorizar os estudantes universitários com base na associação entre a neofobia alimentar e níveis de bem-estar subjetivo geral (e específico ao domínio alimentar), além da percepção dos estudantes em relação aos hábitos alimentares da família. Foi realizado um inquérito entre 372 universitários do Sul do Chile. O questionário incluiu a Food Neophobia Scale (FNS), Satisfaction with Life Scale (SWLS), Satisfaction with Food-related Life (SWFL), Health-related Quality of Life Index (HRQOL-4) e Family Eating Habits Questionnaire (FEHQ). A análise de clusters distinguiu três tipos de universitários: o grupo 1 (26,9%) obteve as pontuações mais altas na FNS, SWLS e SWFL. O grupo 2 (40,8%) teve pontuação alta na FNS, porém as pontuações mais baixas na SWLS e SWFL. O grupo 3 (32,3%) teve a FNS mais baixa e pontuações altas na SWLS e SWFL. O Grupo 2 se destacou por ter pontuação baixa no componente do FEHQ referente à coesão da alimentação familiar. Os resultados sugerem que estudantes neofóbicos e não-neofóbicos têm níveis positivos de satisfação com a vida, e com a vida relacionada à alimentação, e que a satisfação entre estudantes neofóbicos está relacionada aos padrões alimentares da família, sobretudo à coesão da alimentação familiar.

RESUMO

Introduction and objectives: A device called FeelBreathe® (FB) has been designed, developed and patented for inspiratory muscle training (IMT). In order to examine the effects of FB on lung ventilation and gas exchange during exercise, 27 trained male healthy volunteers (age: 32.5 ± 7.2 years) were measured. Methods: Maximum static inspiratory pressure (PImax) and spirometry to determine lung capacity were measured at baseline. We continued with an incremental cycloergometer to determine the VO2 peak. Three days later, each subject performed randomly three identical submaximal cycloergometer tests at 50% between ventilatory thresholds under three different breathing conditions: a) oronasal breathing (ONB), b) nasal breathing (NB) and c) nasal breathing through the FB. Results: FB trial showed lower minute ventilation (VE) and breathing frequency (BF) than NB, which had lower BF, but similar VE than ONB (p < 0.001). The percentage of inspiration time (Ti/Tot) was 7% greater in FB compared to NB and ONB (p < 0.001). Increased end-tidal pressure of CO2 (PETCO2 ) and reduced end-tidal pressure of O2 (PETO2 ) and fraction of O2 expiration (FEO2 ) were found only in FB. Conclusions: FeelBreathe is a new nasal restriction device that stimulates the inspiratory muscles to produce a breathing pattern more efficiency during exercise in well-trained humans (AU)


Introducción y objetivos: un dispositivo llamado FeelBreathe® (FB) se ha diseñado, desarrollado y patentado para el entrenamiento de la musculatura inspiratoria (IMT). Para examinar los efectos de FB en la ventilación pulmonar y el intercambio gaseoso durante el ejercicio, se tomaron medidas de 27 voluntarios varones sanos entrenados (edad: 32,5 ± 7,2 años). Métodos: al inicio del estudio se midieron tanto la presión inspiratoria máxima estática (PIM) y la capacidad pulmonar mediante espirometría. Seguidamente, se realizó un test incremental en cicloergómetro para determinar el VO2 pico. Cada sujeto, tres días más tarde, realizó aleatoriamente tres pruebas idénticas submáximas en cicloergómetro a una intensidad comprendida al 50% entre los umbrales ventilatorios bajo tres condiciones de respiración diferentes: a) respiración oronasal (ONB), b) respiración nasal (NB) y c) la respiración nasal a través del FB. Resultados: la prueba con FB mostró una ventilación minuto (VE) y una frecuencia respiratoria (BF) inferior que en las pruebas de NB, la cual a su vez tenía menor BF, pero similar VE que ONB (p < 0,001). A pesar de esto, FB obtuvo valores similares de VO2 , cociente respiratorio (RER), frecuencia cardiaca (HR) y saturación de oxígeno capilar periférica (SpO2) en comparación con NB y ONB. Esto último puede ocurrir debido en parte al aumento del volumen tidal (VT) y el tiempo de expiración (Tex) en FB hasta el mismo nivel que en la prueba de NB, los cuales fueron un 15% y 14% en ambas pruebas, respectivamente, superiores a ONB (p < 0,001). El porcentaje de tiempo de inspiración (Ti/Tot) fue 7% mayor en la prueba de FB en comparación con NB y ONB (p < 0,001). Solamente en la prueba de FB se encontró un aumento de la presión final de la espiración de CO2 (PETCO2 ) y la reducción de la presión final de la espiración de O2 (PETO2 ) y la fracción de expiración de O2 (FEO2 ). Conclusiones: FeelBreathe es un nuevo dispositivo de restricción nasal que estimula los músculos inspiratorios para producir un patrón de respiración más eficiente durante el ejercicio en los seres humanos bien entrenados (AU)
