Abstract This study aims to analyze the reliability of the test of 8 throws of 3 different variants of handball throws in university students. The participants were 33 males, 20 ± 1.9 years; weight 72.39 ± 8.9 kg; height 176.75 ± 6.07 cm; BMI 23.14 ± 2.3. They were evaluated in 2 sessions separated from each other by a period of one week. The participants executed throws until 8 measurements were recorded in each of the tests, unspecific throws, in support and in the race with 3 steps; the launch speed was recorded with a radar behind the goal. The reliability of the average of the test scores of 8 measurements between the first session and the second was measured with a test-retest test. The following results were obtained: in the nonspecific launch, an ICC= (0.86) was obtained between 95% of confidence, one of CV= (7.43%) and one ES = (0.08). For the toss with support, an ICC = (0.94) was obtained at 95% confidence, one of CV = (4.71%) and an ES = (-0.09). For the running throw, an ICC = (0.96) was obtained at 95% confidence, one of CV = (4.00%) and one ES = (0.05). This study has shown that the test of 8 throws and the 3 variants is a reliable and stable performance measure for university-level students without experience in handball; in relation to the throw variables, all 3 were reliable. Only the nonspecific variable was lower compared to the supported and running pitch.

Os participantes foram testados em 2 sessões separadas por um lapso de 1 semana. Os participantes executaram arremessos até poder registrar 8 medições em cada um dos testes, arremessos não específicos, com apoio e correndo com 3 passos. A velocidade de arremesso foi registrada com um radar pós-gol. A confiabilidade da média dos resultados dos testes de 8 medições entre a primeira sessão e a segunda com um teste de retorno, deu os seguintes resultados: no teste de lançamento não específico, foi obtido um ICC= (0,86) com 95% de confiança, um CV= (7,43%) e um ES= (0,08). Para o lançamento apoiado obtivemos um ICC= (0,94) a 95% de confiança, um CV= (4,71%) e um ES= (-0,09). Para o arremesso de corrida obtivemos um ICC= (0,96) a 95% de confiança, um CV= (4,00%) e um ES= (0,05). Este estudo mostrou que o teste de 8 lances e as 3 variantes é uma medida de desempenho confiável e estável para estudantes universitários sem experiência em handebol. Em relação às variáveis de arremesso, todas as 3 foram confiáveis, apenas a variável não específica foi menor em comparação com o arremesso com suporte e com corrida.

Performance of Holstein-Friesian calves drinking desalinated water in the preweaning period

Background: High salinity of drinking water can adversely affect health and productive performance of calves during artificial rearing. Objective: To evaluate the effect of drinking water total dissolved salts (TDS) content on productive performance of Holstein-Friesian calves during artificial rearing. Methods: Twenty-nine newborn Holstein-Friesian calves weighing 39±0.94 kg at birth were randomly assigned to two treatment groups for 56 d. Treatment 1 (n=14) consisted of drinking water with 1,469±75 mg L-1 TDS, while treatment 2 (n=15) used drinking water from the same source but filtered by reverse osmosis to contain 107±31 mg L-1 TDS. Results: Water intake was numerically affected by TDS concentration, increasing 13% (p>0.08) when drinking low-TDS water (3,554 versus 3,088 ml d-1). Feed intake (dry basis) decreased 26% (500 versus 676 g d-1; p0.05) by TDS content in the drinking water. Conclusion: Desalinated water improves productive performance of Holstein-Friesian calves during artificial rearing.

Conclusão: A dessalinização da água de beber melhora o comportamento produtivo de terneiros Holstein durante o período de lactação artificial..

TOXICIDAD AGUDA DEL HERBICIDA PARAQUAT EN Oreochromis niloticus (CICHLIDAE) Y Macrobrachium olfersii (PALAEMONIDAE) / Paraquat's herbicide acute toxicity in Oreochromis niloticus (Cichlidae) and Macrobrachium olfersii (Palaemonidae)

RESUMEN El Paraquat es un herbicida utilizado en la actividad agropecuaria para controlar hierbas, su modo de acción es por medio de contacto y no selectivo. Debido a su alta solubilidad en agua y baja volatilidad representa un riesgo potencial para organismos acuáticos, principalmente los que son cultivados con aguas superficiales que reciben impacto de la actividad agrícola. La tilapia Oreochromis niloticus y el langostino Macrobrachium olfersii son organismos de importancia comercial para la industria acuícola del estado de Veracruz, México. El objetivo de este estudio fue determinar la Concentración Letal Media (CL50) del herbicida Dasurquat® (ingrediente activo Paraquat) a través de un bioensayo de toxicidad aguda (96 horas). Se utilizaron como especímenes de prueba a juveniles de tilapia O. niloticus (peso promedio = 10 mg, longitud total= 8,75 mm) y otro el ensayo fue con poslarvas de langostino M. olfersii (peso promedio = 5 mg, longitud total= 5,72 mm). Se emplearon cinco concentraciones (5, 10, 20, 40 y 80 μL-1 para el bioensayo con juveniles de tilapia; para el bioensayo con poslarvas de langostino las concentraciones fueron 0,1, 0,2, 0,5, 0,7 y 1 μL-1). El diseño experimental consideró un control negativo, con dos repeticiones y dos réplicas por cada tratamiento. El análisis de datos se realizó con el método Probit para determinar la CL50 a 96 horas, se obtuvo un valor para juveniles de O. niloticus de 17,49 μL-1 con intervalo de confianza (95 %) con límite inferior de 13,75 μL-1 y límite superior 22,25 μL-1, para las larvas de M. olfersii se obtuvo un valor de 0,31 μL-1 con intervalo de confianza (95 %) con límite inferior de 0,26 μL-1 y límite superior 0,35 μL-1. El análisis de varianza demostró que no existió diferencia estadística significativa (p > 0.05) entre las réplicas de los tratamientos. Se concluye que es necesario continuar con estudios para evaluar su toxicidad en organismos acuáticos debido al amplio uso de este herbicida en la actividad agropecuaria, y determinar su riesgo para otras actividades productivas además de la acuicola.

ABSTRACT Paraquat is an herbicide used in the agricultural industry for weed and undergrowth control, its mode of action is by contact and nonselective. Due to its high-water solubility and low volatility, it represents a potential risk for non-target organisms. Oreochromis niloticus tilapia and the prawn Macrobrachium olfersii are important commercial species for Veracruz's aquaculture industry. The objective of this study was to determine the Mean Lethal Concentration (LC50) of the herbicide Dasurquat® (active ingredient Paraquat) through an acute toxicity bioassay (96 hours). Juvenile O. niloticus (average weight = 10 mg, total length = 8.75 mm) and juvenile M. olfersii postlarvae (average weight = 5 mg, total length = 5.72mm) were used as test specimens. Five herbicide concentrations (5, 10, 20, 40 and 80 μL-1 for tilapia and 0.1, 0.2, 0.5, 0.7 y 1 μL-1 for prawn) were applied. The experimental design considered a negative control, with two replications and two replicates for each treatment. Probit analysis determined that the LC50 at 96 hours for O. niloticus was 17.49 μL-1, with a lower 95 % confidence limit of 13.75 μL-1 and an upper limit of 22.25 μL-1, whereas for M. olfersii the LC50 at 96 hours was 0.31 μL-1, with a lower 95 % confidence limit of 0.26 μL-1 and an upper limit of 0.35 μL-1. The analysis of variance showed that there was no significant statistical difference (p > 0.05) between the replicates of the treatments. It is concluded that it is necessary to continue evaluating its toxicity in aquatic organisms due to the wide use of this herbicide in Veracruz's agricultural activity, to determine its potential risk to other activities.

Asociación VACTERL con poliquistosis renal en un recién nacido: reporte de caso

Las malformaciones son causas importantes de mortalidad infantil, enfermedad crónica y discapacidad en muchos países, y ocasionan 3,2 millones de discapacidades al año. La asociación VACTERL involucra defectos vertebrales, atresia anal, fístula traqueoesofágica y displasia renal, así como anormalidades en las extremidades. Nuestro objetivo es describir las características generales de la asociación VACTERL y realizar un acercamiento a otros casos en la literatura. Nuestro caso trata de una recién nacida a las 35 semanas con grave dificultad respiratoria, que ingresa a la UCI neonatal por descompensación hemodinámica. Tiene un antecedente de poliquistosis renal bilateral a las 25 semanas dado por ecografía. En el examen físico se evidencia agenesia de órganos sexuales y ano imperforado, y en la radiografía se observa patrón atelectásico, cardiomegalia y posición dextrógira de la silueta cardiaca. La paciente fue diagnosticada con asociación VACTERL y ano imperforado. Sufrió un paro respiratorio y falleció luego de dos días.

Malformations are important causes of infant mortality, chronic disease and disability in many countries, causing 3.2 million disabilities per year. The VATERL association includes vertebral defects, anal atresia, tracheoesophageal fistula and renal dysplasia, as well as limb abnormalities. This case report aims to provide the general characteristics of the VACTERL association and discuss other cases found in the medical literature. This is the case of a female newborn delivered at 35 weeks of pregnancy with severe respiratory distress, who was admitted to the neonatal ICU due to hemodynamic decompensation. She had a history of bilateral polycystic kidney disease found by ultrasound at 25 weeks of pregnancy. A physical examination showed vaginal agenesis and imperforate anus. Atelectasis, cardiomegaly and dextroposition of the cardiac silhouette were observed in a radiography. The patient was diagnosed with VACTERL association and imperforate anus. She died 2 days after a respiratory arrest.

Andersen-Tawil Syndrome with High Risk of Sudden Cardiac Death in Four Mexican Patients. Cardiac and Extra-Cardiac Phenotypes

ABSTRACT Background: Andersen-Tawil syndrome (ATS) is a cardiac channelopathy that is inherited in an autosomal dominant way, and it is characterized by a triad of periodic paralysis, ventricular arrhythmias, and includes some dysmorphic features with incomplete penetrance and variable expression that result in a challenging diagnosis. Objective: The objective of the study was to describe the cardiac and extra-cardiac phenotype in a cohort of patients with ATS at risk of sudden cardiac death (SCD) to improve its early clinical identification. Methods: In an observational, transversal study, with a deviant case sampling, four female patients with ATS at high risk of SCD were included in the study. They carried the heterozygous pathogenic variants c.407C>T [p.Ser136Phe], c.652C>T [p.Arg218Trp] (n=2), and c.431G>C [p.Gly144Ala] in the KCNJ2 gene. Patients were evaluated by a cardiologist, a clinical geneticist, and a physiatrist. Results: One patient had the classical facial phenotype and the other three had subtle manifestations. The group of patients presented a diverse set of clinical data such as: triangular face, broad forehead, broadening of medial eyebrows, auricular pits, low-set ears, eyelid ptosis, thin lips, mandibular hypoplasia, and diverse types of dental alterations, single transverse palmar crease, camptodactyly, and syndactyly. Long-exercise test showed a decrement in the percentage amplitude up to 44%, classifying patients in IV or V types according to Fournier’s scale. Conclusions: Extra-cardiac manifestations were a common finding in this series of ATS type1 at high risk of SCD. Its recognition could help the clinician in the early identification of patients with ATS, especially for the cardiologist since they are commonly referred only for evaluation of ventricular arrhythmias.

Relationship between anthropometric nutritional status and functional capacity in older adults living in the community / Relación entre estado nutricional antropométrico y condición física funcional en adultos mayores independientes

ABSTRACT Background: The functional fitness of older people may be associated with their nutritional status. Aim: To assess the association between of anthropometric measures with functional fitness in older people. Material and Methods: Cross-sectional study conducted in 75 participants aged 65 to 89 years. Body mass index (BMI), waist-to-height ratio (WHtR), fat mass (FM) and skeletal muscle mass index (SMI) were calculated from anthropometric measures. The functional fitness was determined using the Senior Fitness Test battery. Results: BMI and FM indicated obesity, and WHtR indicated cardiometabolic risk in 49%, 55% and 83% of participants, respectively. SMI indicated a low muscle mass in 91% of females. Performance standards of chair stand, arm curl, 2-min step test and 8-foot up-and-go tests were met in 1%, 8%, 1% and 89% of participants, respectively. Significant negative correlations were found between 2-min step test and BMI, WHtR and FM (r = −0.26, −0.31 and −0.48 respectively). Back scratch had a negative correlation with BMI (r = −0.23) and SMI (rho = −0.28). Significant positive correlations were found between 8-foot up-and-go, WHtR (rho = 0.28) and FM (rho = 0.23), and between 2-min step test and SMI (rho = 0.28). The coefficient of determination (R2) between 2-min step test with BMI, WHtR and FM were 0.05, 0.08 and 0.22, respectively, while the R2 between back scratch and BMI was 0.04. Multiple regression models indicated that FM affected the 2-min step test independently of BMI and WHtR (adjusted R2 = 0.22), however age and sex negatively influenced these associations. Conclusions: Functional fitness of older adults is influenced by nutritional anthropometric measures, particularly BMI, WHtR and FM for aerobic capacity, and BMI for upper limb flexibility.

Introducción: El estado nutricional y la condición física funcional (CFF) pueden estar relacionados en adultos mayores. Objetivo: Analizar la influencia de medidas antropométricas nutricionales sobre CFF. Material y Método: Estudio transversal realizado en 75 adultos de 65 a 89 años. Las variables antropométricas fueron índice de masa corporal (IMC), razón cintura-talla (RCT), masa adiposa (MA) e índice de masa muscular esquelética (IMME). La evaluación de CFF se efectuó con la batería Senior Fitness Test. Resultados: El IMC y MA indicaron obesidad, y RCT indicó riesgo cardiometabólico en 49%, 55% y 83% de los participantes, respectivamente. IMME indicó una baja masa muscular en 91% de las mujeres. El estándar de rendimiento para las pruebas sentarse-levantarse, flexión-codo, paso-2-minutos y levantarse-caminar-sentarse se logró en 1%, 8%, 1% y 89% de los participantes, respectivamente. Se encontraron correlaciones significativas negativas entre paso-2-minutos con IMC, RCT y MA (r = −0.26,-0.31 y-0.48 respectivamente. La misma asociación se observó entre juntar-manos-espalda con IMC (r = −0.23) e IMME (rho = −0.28). Se encontraron correlaciones significativas positivas entre levantarse-caminar-sentarse con RCT (rho=0.28) y MA (rho = 0.23), y entre paso-2-minutos con IMME (rho = 0.28). Los R2 entre paso-2-minutos e IMC, RCT y MA fueron 0.05, 0.08 y 0.22, respectivamente, mientras que el R2 entre juntar-manos-espalda e IMC fue 0.04. Los modelos de regresión múltiple indicaron que MA afectó la prueba paso-2-minutos independientemente de IMC y RCT (R2 ajustado = 0.22), aunque la edad y sexo afectaron negativamente estas asociaciones. Conclusiones: La CFF de adultos mayores es influenciada por alteraciones evidenciadas por medidas antropométricas nutricionales, particularmente IMC, RCT y MA sobre la capacidad aeróbica, e IMC sobre la flexibilidad de extremidad superior.

Aim: To seek for an association between PF and HRQOL in non-disabled community-dwelling Chilean older adults. Material and Methods: One hundred and sixteen subjects participated in the study. PF was assessed using the Senior Fitness Test (SFT) and hand grip strength (HGS). HRQOL was assessed using eight dimensions provided by the SF-12v2 questionnaire. Binary multivariate logistic regression models were carried out considering the potential influence of confounder variables. Results: Non-adjusted models, indicated that subjects with better performance in arm curl test (ACT) were more likely to score higher on vitality dimension (OR > 1) and those with higher HGS were more likely to score higher on physical functioning, bodily pain, vitality and mental health (OR > 1). The adjusted models consistently showed that ACT and HGS predicted a favorable perception of vitality and mental health dimensions respectively (OR > 1). Conclusions: HGS and ACT have a predictive value for certain dimensions of HRQOL.

Efecto de los juegos reducidos en la composición corporal y la condición física aeróbica en un grupo de adolescentes escolares / Effects of small-sided exercises on body composition and maximal oxygen uptake in adolescents

Background: The regular practice of physical activity contributes to weight control and improves maximal oxygen uptake (VO2max), socialization and quality of life. Aim: To determine the effect of moderate-to-vigorous physical activity on body composition and VO2max in a group of overweight school-age males. Material and Methods: We studied fifty-five overweight males aged 15.6 ± 0.7 years. Participants were divided in two groups (experimental and control groups). The intervention in the experimental group was the practice of small-sided games during 60 minutes, two days per week and during 11 weeks. At baseline and the end of the intervention, body composition was measured using bioimpedance and VO2max was calculated using the Course Navette test. Results: A 7% reduction in the percentage of body fat and a 9% increase in VO2max were observed in the experimental group (p < 0.01). No changes were recorded in the control group. Conclusions: Eleven weeks of small-sided exercises performed twice per week increased VO2max and reduced fat mass in overweight adolescents.

Psychometric Properties of the Mexican Version of the Mindful Attention Awareness Scale (MAAS) / Propiedades psicométricas de la versión mexicana de la escala de atención Plena (MAAS)

This study presents a translation of the Mindful Attention Awareness Scale (MAAS) into Mexican Spanish, and examines its psychometric properties as well as its relationship with socio-demographic variables. The MAAS measures the frequency with which people experience mindful states. A sample of N = 622 healthy adult Mexicans completed the MAAS. A smaller sub-sample (n=195) completed the Five-Facet Mindfulness Questionnaire (FFMQ), a well-known mindfulness measure, to obtain concurrent validity. Exploratory factor analysis (EFA) revealed a one-factor solution, and reliability coefficients were adequate. Confirmatory factor analysis (CFA) showed adequate goodness of fit indexes. Moreover, relationships between Mexican Spanish MAAS scores and socio-demographic variables were also explored, and differences between-groups were found in mean scores both in alcohol consumers and religious practitioners. No other significant differences between groups were found. Results suggest that the Mexican version of the MAAS is a reliable and valid instrument to use with a healthy adult Mexican sample.

Este estudio presenta una traducción de la Mindful Attention Awareness Scale (Escala de Atención Plena) al español mexicano y examina sus propiedades psicométricas, así como su relación con variables sociodemográficas. La Escala de Atención Plena mide la frecuencia con la que las personas experimentan estados de atención plena. Una muestra de N=622 adultos mexicanos sanos completaron la Escala de Atención Plena. Una submuestra más pequeña (n=195) completó el Cuestionario de Cinco Facetas de la Atención Plena, el cual es una escala bien conocida de atención plena, para obtener validez concurrente. El análisis factorial exploratorio reveló una solución unifactorial y los coeficientes de confiabilidad fueron adecuados. El análisis factorial confirmatorio mostró índices adecuados de bondad de ajuste. Además, también se exploraron las relaciones entre la versión Mexicana del MAAS y variables sociodemográficas, encontrándose diferencias entre grupos tanto en consumidores de alcohol como en practicantes de religión. No se encontraron otras diferencias significativas entre grupos. Los resultados sugieren que la versión mexicana de la MAAS es un instrumento confiable y válido para utilizarse con población mexicana adulta y sana.

Eficacia y seguridad de Nitazoxanida comparada con Albendazol en el tratamiento de Giardiasis sintomática en niños de Trujillo, Perú 2008 - 2009 / Efficacy and safeness Nitazoxanide compared with Albendazole in symptomatic Giardiasis children treatment in Trujillo, Perú 2008 - 2009

Giardiasis constituye un problema de salud pública de mayor prevalencia en países en vías de desarrollo, asociada a la pobreza y un deficiente sistema sanitario con una elevada afección en niños. El objetivo es comparar la eficacia y seguridad de Nitazoxanida y Albendazol en el tratamiento de giardiasis sintomática en niños. La población de estudio estuvo constituida por niños de ambos sexos que acudieron al consultorio de Medicina General del Centro Médico Funegra de Trujillo cuya edad estuvo comprendida entre los 3 a 14 años, con diagnóstico confirmado de giardiasis, divididos en dos grupos: aquellos que recibieron tratamiento A (Albendazol) y aquellos con tratamiento B (Nitazoxanida) que cumplieron con los criterios de inclusión y exclusión establecidos. El promedio de edad para el grupo A fue de 6,73 ± 3,01 y en el grupo B, 7,04 ± 3,05. Las manifestaciones clínicas al inicio del esquema terapéutico estuvieron lideradas por dolor abdominal. Hubo mayor porcentaje de resolución clínica y coproparasitológico para el grupo Nitazoxanida, no hubo diferencia estadística significativa en este aspecto con el grupo de Albendazol. Nitazoxanida mostró mayor porcentaje de efectos adversos que Albendazol. Se concluyo que Albendazol y Nitazoxanida demostraron ser eficaces y seguros en el tratamiento de giardiasis sintomática en niños. La eficacia de Albendazol fue de 93,8 % y la de Nitazoxanida fue de 96,9 %. Los principales efectos adversos fueron: dolor abdominal, hiporexia y diarrea, siendo más frecuente dolor abdominal en el grupo Nitazoxanida.

Giardiasis is a public health problem, most prevalent in developing countries associated with poverty and poor health care system with a high condition in children. The objetive was to compare the efficacy and safeness of nitazoxanide and albendazole in the treatment of symptomatic giardiasis in children.
