Perceived physical literacy in children and early adolescents: Two valid and reliable versions of the PL-C Quest.

Perceived physical literacy contributes to the understanding of individuals' physical activity (PA) engagement. It is important a scale is validated in the population of interest. Also, the type of administration may affect reliability and validity. So, the aim of this study was twofold: 1) to examine evidence of validity and reliability of the Spanish version of the Physical Literacy for Children Questionnaire (PL-C Quest) in a cohort of children and adolescents and 2) to assess two versions of administering the scale. The study was conducted in two stages, depending on the administration format of the PL-C Quest (double-dichotomous, and four-point response style) in a cohort of 2004 (n1 = 916; n2 = 1088) students. In both administration forms, evidence of validity (relation with other variables, i.e., concurrent and predictive, and structural validity), invariance (between boys and girls) and reliability (test-retest and internal consistency) were examined. There was evidence of validity for both administration types, with adequate reliability and good to excellent test-retest reliability for both administration forms. Both methods of administration for the PL-C Quest can capture perceived physical literacy in Spanish 8- to 14-year-old children and early adolescents.

Effect of Reduced Feedback Frequencies on Motor Learning in a Postural Control Task in Young Adults.

The effects of the use of reduced feedback frequencies on motor learning remain controversial in the scientific literature. At present, there is still controversy about the guidance hypothesis, with some works supporting it and others contradicting it. To shed light on this topic, an experiment was conducted with four groups, each with different feedback frequencies (0%, 33%, 67%, and 100%), which were evaluated three times (pre-test, post-test, and retention) during a postural control task. In addition, we tested whether there was a transfer in performance to another similar task involving postural control. As a result, only the 67% feedback group showed an improvement in their task performance in the post-test and retention evaluations. Nevertheless, neither group showed differences in motor transfer performance compared to another postural control task. In conclusion, the findings of this paper corroborate the hypothesis of guidance and suggest that the use of a reduced frequency of 67% is a better option for improving motor learning than options that offer feedback at a lower frequency, at all trials or not at all.

Impacto del sexo del donante y del receptor en los niveles de hemoglobina de los receptores de riñón al año de seguimiento / Impact of donor and recipient sex on hemoglobin levels of kidney recipients at one-year follow-up

Introdución:El trasplante renal es la mejor terapia de reemplazo renal, el cual depende de múltiples factores para un funcionamiento como condiciones del donador, del receptor y sociodemográficas.Objetivo: Evaluar el efecto del sexo de los donadores y receptores durante el primer año después del trasplante en los valores de hemoglobina. Material y Método: Estudio de cohorte retrospectiva de receptores renales del 2014 al 2019, realizado en el Hospital de Especialidades del Centro Médico Nacional Siglo XXI (Ciudad de México). Se incluyeron a todos los trasplantados, excluyendo fallecidos, pérdida del injerto y pérdida de seguimiento en la institución. Se estudiaron sexo y edad del donante y receptor, tipo de donante renal (vivo o fallecido), hemoglobina antes del trasplante renal y la hemoglobina al año del trasplante, y creatinina sérica.Resultados: Se analizaron 914 pacientes, se excluyeron 109 por diversos motivos, quedando 805 pacientes que completaron los 12 meses de seguimiento. En el caso de donaciones de masculino a femenino, la mediana de hemoglobina del receptor a los 12 meses fue de 15,2 g/dL (Percentil 25-Percentil 75: 13,7-16,0 g/dL), de masculino a masculino de 15,2 g/dL (Percentil 25-Percentil 75: 13,4-16,6 g/dL), de femenino a femenino de 14,0 g/dL (Percentil 25-Percentil 75: 12,4-15,3 g/dL) y femenino de masculino de 13,5 g/dL (Percentil 25-Percentil 75: 12,5-14,8 g/dL).Conclusiones: Los niveles de hemoglogina no parecen estar influenciados por la masa nefronal, como sí otras funciones del injerto (depuración de creatinina). La regulación de la hemoglobina guarda relación con el sexo del receptor (AU)

Introduction: Kidney transplantation is the optimal renal replacement therapy, dependent on various factors such as donor, recipient, and sociodemographic conditions for optimal functioning. Objective: To assess the effect of donor and recipient sex during the first year post-transplant on hemoglobin values.Material and Method: A retrospective cohort study of kidney recipients from 2014 to 2019 was conducted at the Hospital de Especialidades of Centro Médico Nacional Siglo XXI (Mexico City). All transplant recipients were included, excluding those who died, experienced graft loss, or were lost to follow-up at the institution. Donor and recipient sex and age, type of renal donor (living or deceased), hemoglobin before renal transplant, hemoglobin at one-year post-transplant, and serum creatinine were studied.Results: A total of 914 patients were analyzed, with 109 excluded for various reasons, resulting in 805 patients who completed the 12-month follow-up. In cases of male-to-female donations, the median recipient hemoglobin at 12 months was 15.2 g/dL with an interquartile range (IQR 25-75) of 13.7-16.0 g/dL; male-to-male donations had a median of 15.2 g/dL (IQR 25-75 13.4-16.6 g/dL); female-to-female donations had a median of 14.0 g/dL (IQR 25-75 12.4-15.3 g/dL), and female-to-male donations had a median of 13.5 g/dL (IQR 25-75 12.5-14.8 g/dL).Conclusions: Hemoglobin levels do not appear to be influenced by nephron mass, as with other graft functions (creatinine clearance). Hemoglobin regulation is associated with the recipient’s sex (AU)

A Classroom-Based Intervention to Promote Physical Literacy in Children: ALPHYL Study Protocol.

Physical literacy is crucial for children's appropriate development and physical, social and mental health. In a school setting, class-based physical activity (PA) interventions are considered to be appropriate programs to foster PA participation and cognitive development. The purpose of this project, named the Active Learning in PHYsical Literacy (ALPHYL) study, was to describe a multicomponent classroom-based physically-active learning randomised control trial (RCT) in primary school children. The main purpose was to promote children's physical literacy, academic achievement and cognitive function. The ALPHYL study is mainly based on physical literacy, active school models and the Supportive, Active, Autonomous, Fair and Enjoyable principles. The ALPHYL is an 8-10-week RCT to be conducted in six primary schools (12 classes) in Valencia (Spain) and its metropolitan area. Schools will be randomly assigned to the intervention or waiting-list control group. After a 30 h in-person training course for teachers and weekly meetings in the three months of resource preparation, the ALPHYL intervention will be conducted in physical education (PE) and non-PE lessons by teachers. The intervention consists of at least three daily sessions of physically active learning in addition to model-based PE teaching. Its feasibility will be evaluated weekly according to the Reach, Effectiveness, Adoption, Implementation and Maintenance framework. To assess its effectiveness, a pre-test, post-test and retention (8-10 weeks post-intervention) with primary outcomes (i.e., PA level, motor competence, perceived motor competence and PL, motivation, perceived social support, academic achievement and cognitive function), secondary outcomes and covariates will be collected.

Cognitive CAMSA: an ecological proposal to integrate cognitive performance into motor competence assessment.

Purpose: To profile the participants using a system of self-organizing maps (SOM) based on their motor and cognitive performance during a dual-task version of the Canadian Agility and Movement Skill Assessment (Cognitive CAMSA). Methods: A total of 169 secondary school students (39.3% girls) volunteered to participate. The original CAMSA, cognitive CAMSA, the Corsi and Digit Span tests were used to assess (a) motor competence, (b) motor competence with cognitive load, and (c) cognitive performance, respectively. SOMs and the k-means clustering algorithm were used to establish the adolescents' dual-task performance profiles. Results: Including decision making based on verbal and visual cues in the original CAMSA significantly increased the participants' total scores but also the time required to complete the test, while the skill score remained unchanged. However, not all the participants showed changes in their performance in the same direction during the cognitive CAMSA. Person-centered analyses by SOMs and k-means clustering identified six performance profiles with variations in the cognitive, motor skill, and time scores (H5 = 146.15, H5 = 102.68, and H5 = 108.07, respectively; all p < 0.01). Conclusion: The cognitive CAMSA was shown to be a feasible field-motor test for assessing motor competence with a cognitive load in an ecological setting. Some of the profiles identified in the SOM approach represented adolescents with similar motor and cognitive performance in dual-task or single-task contexts, although other participants obtained high motor competence in single and dual-tasking while their cognitive performance declined or rose more in dual-task than in single task situations. The cognitive CAMSA emerges as a tool of great potential, applicable in educational and sports environments, to know subjects' characteristics and try to individualize the interventions accordingly with their dual-task profile.

Efectividad de una intervención educativa y asistencial en la prevalencia de la lactancia materna en el área sanitaria del Hospital de Valme / Effectiveness of an educational and care intervention in the prevalence of breastfeeding in the health area of the Hospital de Valme

Objetivo: Valorar la efectividad de un programa de intervención asistencial hospitalaria respecto al procedimiento habitual sobre la evolución de la lactancia materna. Diseño: Experimental, con asignación aleatoria, paralelo y controlado. Sujetos y métodos: Mujeres que parieron en el Área Sanitaria del Hospital Universitario de Valme (Sevilla) entre noviembre de 2003 y 2005. Criterios de inclusión: primíparascon parto eutócico, sin patología, edad entre los 20 y los 35 años, recién nacidos (RN) a término y con peso superior a 2.500 g, Apgar a los 10 minutos >8. Las mujeres se dividieron en 4 grupos: grupo A: mujeres con educación maternal (EM) e intervención asistencial (IA); Grupo B: mujeres sin EM e IA; grupo C: mujeres con EM y procedimiento habitual (PH), y grupo D: mujeres sin EM y PH. Resultados: La prevalencia al inicio y la duración media de algún tipo de lactancia materna fue mayor en el grupo A, y se encontraron diferencias estadísticamente significativas entre este grupo y el grupo D. Conclusiones: Las mujeres que recibieron la asociación de apoyo en los periodos prenatal y posnatal mostraron una mayor prevalencia y duración de lactancia materna que aquellas que no la recibieron. El programa por sí mismo también aumentó con diferencias significativas la lactancia materna exclusiva de inicio y la mixta a los 3 meses. (AU)

Objective: To assess the effects of a hospital-based program involving a health care intervention, versus the usual procedure on the evaluation of breastfeeding. Design: A randomized, controlled, parallel, experimental study. Population and methods: Women who gave birth in the Health Area of the University Hospital of Valme, in Seville, between November 2003 and 2005. The inclusion criteria were: healthy, primiparous women between 20 and 35 years of age, with normal delivery of a full-term infant weighing over 2500 g, with a 10-minute Apgar score >8. The women were divided into four groups: group A, women with parenthood education (PE) and health care intervention (HCI); group B, women without PE and with HCI; group C, women with PE and the usual procedure; and group D, women without PE with the usual procedure. Results: The prevalence of the initiation of breastfeeding and the mean duration of some form of breastfeeding was greater in group A, and there were statistically significant differences between this group and group D. Conclusions: The prevalence and duration of breastfeeding was greater among the women who received prenatal and postnatal support than among those who did not. The program also significantly increased the practice of exclusive breastfeeding at the beginning and mixed feeding at 3 months. (AU)

Neumotórax espontáneo y parto: a propósito de un caso / Spontaneous pneumothorax and delivery: a case report

La aparición de un neumotórax espontáneo durante la gestación es infrecuente. Sin embargo, debido a los cambios fisiológicos del sistema respiratorio durante el embarazo, cualquier entidad que provoque una alteración en la ventilación afecta gravemente tanto a la gestante como al feto, por lo que ante una gestante que presente disnea y dolor torácico debería excluirse el diagnóstico de neumotórax. Se expone el caso de una mujer multípara con 39 semanas de amenorrea que presentó un neumotórax espontáneo; tras su ingreso en la UCI y la colocación de tubo pleural con válvula de Heimlich, se inicia trabajo de parto, con nacimiento de un niño sano tras parto instrumentado con analgesia epidural. Posparto de evolución normal; a los dos días se retira el tubo torácico y se remite para tratamiento quirúrgico definitivo

The onset of spontaneous pneumothorax during pregnancy is uncommon. However, due to the physiological changes of the respiratory system during pregnancy, any entity that causes an alteration in the ventilation, seriously affects both the pregnant woman and fetus. Pneumothorax should be excluded when presented with a pregnant woman with dyspnea and chest pain. We report the case of a multiparous woman with 39 weeks of amenorrhea who presented spontaneous pneumothorax. After admission to the ICU and placement of a pleural tube with a Heimlich valve, labour began. Epidural analgesia was used, and a healthy child was born after instrumental delivery. Postpartum had a normal evolution; Two days later, the Thoracic tube was removed and the mother referred for definitive surgical treatment

¿Influye la Luna en el parto? / The moon and delivery

En diferentes culturas y mitologías se relaciona a la Luna con la fertilidad, embarazo y parto. Los profesionales de la obstetricia también recurrimos al tópico del incremento de presión asistencial en los días de luna llena. Existen muchos estudios que tratan de relacionar el proceso del parto con las fases lunares llegando a resultados contradictorios. Pretendemos comprobar si existen bases que apoyen estas creencias populares y establecer si la fase lunar influye en la distribución de los partos. Se ha realizado un estudio descriptivo transversal sobre un total de 1.715 partos espontáneos distribuidos a lo largo de diez ciclos lunares completos. Se ha realizado un análisis descriptivo e inferencial, ANOVA de una vía y prueba de Kruskal Wallis, en las tres bases de datos, general, primíparas y multíparas, contemplando el total de partos por fase, la media en cada fase, así como el día central en cada fase del ciclo lunar. Las diferencias encontradas en la distribución de los partos a lo largo de las cuatro fases del ciclo lunar, así como la comparación de las medias y la comparación del número de partos en el día central de cada fase no son estadísticamente significativas (AU)

[The moon and delivery]. / Influye la Luna en el parto?

In different cultures and mythologies, the moon is related with fertility, pregnancy and delivery. Professional obstetricians also notice an increase in care demands on the days when the moon is full. Many studies have been made which try to correlate delivery processes to the phases of the moon with contradictory results. The authors plan to try to find any basis in fact which support these popular beliefs and to discover if lunar phases bear an influence on the distribution of deliveries. They carried out a descriptive transversal study on a total of 1715 unassisted deliveries over the course of ten complete lunar cycles. The authors have carried out a descriptive and inferential analysis, a one way ANOVA and a Kruskal Wallis test on their three data bases which are general, primipara and multipara in which they contemplated the total number of deliveries per phase, the mean of each phase, as well as the central day in each phase of the lunar cycle. The differences found in the distribution of deliveries over the four lunar phases, along with the comparison of the means and the comparison of the number of deliveries on the central day in each phase are not statistically significant. The different phases in the lunar cycle and especially the full moon do not appear to have any influence over the distribution of deliveries in this study.

[Promoting breastfeeding]. / Promocionando la lactancia materna.

The World Health Organization considers maternal breast feeding to be the ideal manner to feed a newborn child, as well as being a unique biological and emotional base, and recommends breast feeding to be the exclusive feeding method until the age of six months. After a period of massive abandonment caused by multiple socio-cultural causes beginning about a half century ago, breast feeding is now starting to make a slow recuperation. In Spain, there is an initial predisposition to breast feed of about 80%. However, in spite of the initiatives carried out by organizations and professional groups, the admission of mother and child into a hospital has a negative effect on breast feeding. Therefore, the authors have designed an program to use in a health education course to promote breast feeding while under hospital care.

Promocionando la lactancia materna / Promoting maternal breast feeding an educational program

La OMS considera la lactancia materna la forma ideal de alimentar al recién nacido y una base biológica y emocional única, recomendando lactar de manera exclusiva hasta los seis meses de vida. Tras un período de abandono masivo mediado por múltiples causas socioculturales que se inició hace medio siglo, nos encontramos ante una lenta recuperación. España se encuentra con una prevalencia inicial que supera el 80 por ciento. Sin embargo, a pesar de las iniciativas llevadas a cabo por entidades y colectivos de profesionales en el medio hospitalario para fomento y promoción de la lactancia materna, el ingreso hospitalario de ma-dre e hijo ejerce un efecto negativo para la lactancia materna. Por ello se ha diseñado un programa de intervención en educación para la salud para el fomento de la lactancia materna en el medio hospitalario (AU)
