Somatotipo de atletas de taekwondo del centro de entrenamiento regional de Valparaíso, Chile / Somatotype of taekwondo athletes at the regional training center in Valparaíso, Chile

RESUMEN: El objetivo del estudio fue determinar el somatotipo de atletas de Taekwondo del Centro de Entrenamiento Regional (CER) de Valparaíso, Chile. Se evaluaron a los primeros cuatro clasificados según sexo (8 deportistas en total), hombres (18,75 ± 2,62 años) y mujeres (18,50 ± 1,91 años), competidores activos a nivel nacional e internacional en la disciplina deportiva. Para la evaluación se consideraron las normas establecidas por la International Society for the Advancement of Kinanthropometry (ISAK) y el grupo español de Cineantropometría (GREC). Los materiales utilizados fueron el kit Innovare básico CESCORF®, tallímetro y balanza TANITA®. Para determinar el somatotipo se consideró la propuesta de Heath & Carter. Los resultados encontrados muestran en el género masculino una clasificación del somatotipo de mesomorfo balanceado (2,5-4,0-3,0), mientras que en el género femenino se clasificó como mesomorfo - endomorfo (3,3-3,6-2,3). Se concluye que en ambos géneros predomina el componente mesomorfia, las mujeres presentan un mayor nivel de endomorfia y un menor desarrollo de la mesomorfia en comparación con los hombres.

SUMMARY: The aim of the study was to determine the somatotype of taekwondo athletes at the Regional Training Center (CER) in Valparaíso, Chile. The first four were classified according to sex (8 athletes in total), men (18.75 ± 2.62 years) and women (18.50 ± 1.91 years), all of them active competitors in the discipline nationally and internationally. For the evaluation, the standards established by the International Society for the Advancement of Kinanthropometry (ISAK) and the Spanish Group of Cineanthropometry (GREC) were considered. The materials used were CESCORF® basic Innovare kit, TANITA® weight/height scale. To determine the somatotype, the Heath & Carter proposal was considered. The results showed that in men a classification of the somatotype of balanced mesomorph (2.5-4.0- 3.0), while in women it was classified as mesomorphic - endomorphic (3,3-3,6 - 2,3). It is concluded that in both sexes the mesomorphic component predominates, women present a higher level of endomorphy and a lower development of mesomorphy compared to men.

Asociación entre índices antropométricos de salud y condición física en mujeres mayores físicamente activas / Association between health anthropometric indexes with physical fitness in physically active elderly women

Resumen: Objetivo: Asociar los índices antropométricos de salud con la condición física de las mujeres mayores (MM) que participan en talleres de ejercicio físico. Material y métodos: Participaron 272 mujeres chilenas mayores de 60 años. Las variables correspondieron al IMC, perímetro de cintura (PC), índice cintura estatura (ICE) y condición física (CF). Se realizaron correlaciones a través del coeficiente de Pearson o Spearman, y asociaciones bivariadas mediante ji cuadrada de Pearson y el test exacto de Fisher, considerando un p<0.05. Resultados: De las MM, 70.8% alcanzó sobrepeso u obesidad; y 68.8% y 96% riesgo cardiometabólico de acuerdo con PC e ICE, respectivamente. Su CF presentó un rendimiento igual (53.5%) o superior (33.8%) según su edad y sexo. Se encontraron correlaciones inversas entre estado nutricional y riesgo cardiometabólico con las pruebas de CF (excepto la agilidad y equilibrio dinámico, en donde la relación fue directa), y asociación directa con juntar manos. Conclusiones: El exceso de peso en MM físicamente activas no afecta su rendimiento físico-funcional; sin embargo, el riesgo cardiometabólico se asocia inversamente con la funcionalidad motriz.

Abstract: Objective: To associate health anthropometric indexes with physical fitness of elderly women (EW) who participate in physical exercise workshops. Materials and methods: 272 Chilean women over 60 years took part in the study. The variables studied were BMI, waist circumference (WC), waist-height index (WHI) and physical fitness (PF). Correlations were made through the Pearson or Spearman coefficient, and bivariate associations using Pearson's Chi-square and the Fisher's exact test, considering p<0.05. Results: 70.8% of the EW were overweight or obese; 68.8% and 96% were at cardiometabolic risk due to their WC and WHI, respectively. Their PF showed equal performance (53.5%) or higher (33.8%) according to their age and gender. Inverse correlations were found between nutritional status and cardiometabolic risk with PF tests (except for agility and dynamic balance [direct]), and direct association with back scratch test. Conclusions: Excess weight in physically active EW would not affect their physical-functional performance; however, cardiometabolic risk would be inversely associated with motor function.

Pleomorphic Adenoma in a Young Female: Case Report / Adenoma Pleomórfico en una Mujer Joven: Reporte de Caso

ABSTRACT: Pleomorphic adenoma (PA) is the most common benign salivary gland neoplasm and it is frequently diagnosed in the third and fourth decade with predilection for women. PA is the most common benign lesion of minor salivary glands in children and adolescents, being the palate one of the most frequently affected site of minor salivary glands. Herein, we present a case report of a PA of the hard palate diagnosed in a 15-year-old female and a review of the Englishliterature of the reported cases of PA in children and adolescents in the hard palate.

RESUMEN: El adenoma pleomórfico (AP) es la neoplasia benigna más común de las glándulas salivales y se diagnostica frecuentemente en la tercera y cuarta década con predilección por las mujeres. El AP es la lesión benigna más común de las glándulas salivales menores en niños y adolescentes, siendo el paladar uno de los sitios más frecuentemente afectados de las glándulas salivales menores. En este trabajo se presenta un relato de caso de un AP de paladar duro diagnosticado en una mujer de 15 años de edad y una revisión de la literatura en inglés de los casos reportados de AP en niños y adolescentes en paladar duro.

Arsenic, cadmium, mercury, sodium, and potassium concentrations in common foods and estimated daily intake of the population in Valdivia (Chile) using a total diet study.

This study was designed to estimate the dietary intake of total arsenic, inorganic arsenic, cadmium, mercury, sodium, and potassium by the general adult population (aged 18-65) of Valdivia, Chile. Calculations were based on a 24-h dietary recall survey. The highest dietary intake of t-As (73.0 µg/day), i-As (20.0 µg/day), Cd (18.0 µg/day), Hg (5.8 µg/day), Na+ (3112.8 mg/day), and K+ (2077.5 mg/day) were for 70-kg adults. Estimating carcinogenic risk (CR > 4 × 10-4) due to exposure to i-As indicated that consumers remain at low risk for cancer. The cumulative health risk was evaluated by summing the target hazard quotient of cadmium (0.26) mercury (0.27) and inorganic arsenic (0.96); this calculation allows us to express the total target hazard quotient as 1.50 where a value > 1 indicates that there is a potential health risk for the population. Total intake of Cd and Hg were therefore within the limits estimated as being safe whereas Na+ and K+ intake for the Valdivia population did not follow the recommended values established by the World Health Organization (WHO). The Na+ intake exceeded the daily recommended intake while K+ intake was lower than the daily recommended intake. This indicates a health risk for the Valdivia population.

Direct measurement of interaction forces between bovine serum albumin and poly(ethylene oxide) in water and electrolyte solutions.

The net interaction between a probe tip coated with bovine serum albumin (BSA) protein and a flat substrate coated with poly(ethylene oxide) (PEO) polymer was measured directly on approach in water and electrolyte solutions using AFM. The approach force curve between the two surfaces was monotonically repulsive in water and in electrolyte solutions. At pH ~5, slightly above the isoelectric point (pI) of BSA, and at large distances, the force was dominated by electrostatic repulsion between the oxygen atoms of the incoming protein with those belonging to the ether groups of PEO. Such repulsive force and range decreased in NaCl. Under physiological conditions, pH 6, BSA is definitely charged and the electrostatic repulsion with ether groups in PEO appears at larger separation distances. Interestingly, at pH 4, below the pI of BSA, the repulsion decreased because of an attractive, although weak, electrostatic force that appeared between the ether groups in PEO and the positively charged amino groups of BSA. However, for all solution conditions, once compression of PEO begun, the net repulsion was always dominated by short-range polymeric steric repulsion and repulsive enthalpy penalties for breaking PEO-water bonds. Results suggest that PEO in mushroom conformation may also be effective in reducing biofouling.

Estimation of the dietary intake of cadmium, lead, mercury, and arsenic by the population of Santiago (Chile) using a Total Diet Study.

Dietary intake of arsenic (As), cadmium (Cd), mercury (Hg), and lead (Pb) by the population of Santiago (Chile) was determined using a Total Diet Study in the market basket modality. After conducting a survey of the foods consumed in the last 24 h, the most consumed food products were included in the basket. Subsequently, they were cooked or prepared according to typical Chilean procedures and grouped into 17 food categories according to their chemical characteristics. The fish and shellfish group had the highest contents of As (1351 ng/g wet weight, ww), Cd (277 ng/g ww), and Hg (48 ng/g ww), while the sugar group had the highest content of Pb (251 ng/g ww). For a person with a body weight of 68 kg, the dietary intakes of As (77 microg/day), Cd (20 microg/day), Hg (5 microg/day), and Pb (206 microg/day) are lower than the provisional tolerable weekly intake values established by the FAO/WHO. Consequently, the total intakes of As, Cd, Hg, and Pb in Santiago (Chile) are within the limits estimated as safe.
