Physical Exercise Program for Elderly Subjects in the “Club Nueva Vida”, in Tunja City

A descriptive, case series intervention study was performed to identify changes in physical qualities, aerobic power, flexibility, strength and body composition amongst 20 elderly subjects belonging to the “Club Nueva Vida” in Tunja City, during the second period of 2005. A PRE and POST assessment of their physical qualities was applied after a 16 week physical exercise program.Results showed an increase in the average of the static muscle streneth from 0.27 to 0.30 Newtons. Standard deviation diminished in 0.1. The dynamic strength measure by the push up test improved in 10% a 35% improved in 10% a 35% improved their. Cardiovascular capability until to high levels of 80% there were not significant changes in the body weight between measures taken before and after the program application. The results obtained with the sit and reach test did not show statistically significant differences. Hower in other flexibility tests the results changed from bad ranges to middle and good ones. The enrolled population was stable during the development of the exercise program. This study concludes that elderly adults acquire changes in their physical quality features after exercise intervention. Physical exercise programs in elderly adults must involve strength activities for upper limbs, trunk and aerobic power activities. The “Beliefs Health Model” is a adherence to reach compliance and maintenance in physical exercise.

Análisis económico de las vacunas 10-valente y 13-valente contra neumococo: revisión sistemática

Introducción: Las vacunas clásicamente han representado un método económico y eficaz para el control y prevención de múltiples enfermedades infecciosas. En los últimos años se han introducido nuevas vacunas contra neumococo a precios elevados, y los diferentes análisis económicos a nivel mundial de estas vacunas no muestran tendencias. El objetivo de este trabajo era resumir la evidencia existente a través de los diferentes estudios económicos evaluando las dos vacunas de segunda generación contra neumococo en la población a riesgo. Metodología: En este trabajo se realizo una revisión sistemática de la literatura en 8 bases de datos localizadas en diferentes partes del mundo y también que tuvieran literatura gris. Los artículos fueron inicialmente evaluados acorde a su titulo y resumen, posteriormente los elegidos se analizaron en su totalidad. Resultados: Se encontraron 404 artículos, de los cuales 20 fueron incluidos en el análisis final. Se encontró que la mayoría de los estudios se realizaron en áreas donde la enfermedad tiene una carga baja, como es Norte América y Europa, mientras que en los lugares del mundo donde la carga es mas alta, se realizaron pocos estudios. De igual manera se observo que la mayoría de los estudios mostraron por los menos ser costo efectivos respecto a la no vacunación, y en su totalidad las dos vacunas de segunda generación mostraron costo efectividad respecto a la vacunación con PCV-7. Los resultados de los estudios son muy heterogéneos, hasta dentro del mismo país, señalando la necesidad de guías para la conducción de este tipo de estudios. De igual manera, la mayoría de los estudios fueron financiados por farmacéuticas, mientras en un numero muy reducido por entes gubernamentales. Conclusiones: La mayoría de los estudios económicos sobre las vacunas de segunda generación contra neumococo han sido realizados en países con un alto índice de desarrollo económico y patrocinados por farmacéuticas. Dado que la mayoría de la carga de la enfermedad se encuentran en regiones con un menor nivel de desarrollo económico se deberían realizar mas en estas zonas. De igual manera, al ser la vacunación un asunto de salud publica y con un importante impacto económico los gobiernos deberían estar mas involucrados en los mismos.

Reference values for handgrip strength in among healthy young adults

Background: Isometric grip strength, evaluated with a handgrip dynamometer, is a marker of current nutritional status and cardiometabolic risk and future morbidity and mortality. We present reference values for handgrip strength in healthy young Colombian adults (aged 18 to 29 years). Methods: The sample comprised 5.647 (2.330 men and 3.317 women) apparently healthy young university students (mean age, 20.6±2.7 years) attending public and private institutions in the cities of Bogota and Cali (Colombia). Handgrip strength was measured two times with a TKK analogue dynamometer in both hands and the highest value used in the analysis. Sex- and age-specific normative values for handgrip strength were calculated using the LMS method and expressed as tabulated percentiles from 3 to 97 and as smoothed centile curves (P3, P10, P25, P50, P75, P90 and P97). Results: Mean values for right and left handgrip strength were 38.1±8.9 and 35.9±8.6 kg for men, and 25.1±8.7 and 23.3±8.2 kg for women, respectively. Handgrip strength increased with age in both sexes and was significantly higher in men in all age categories. The results were generally more homogeneous amongst men than women. Conclusions: Sex- and age-specific handgrip strength normative values among healthy young Colombian adults are defined. This information may be helpful in future studies of secular trends in handgrip strength and to identify clinically relevant cut points for poor nutritional and elevated cardiometabolic risk in a Latin American population. Evidence of decline in handgrip strength before the end of the third decade is of concern and warrants further investigation

Conflict and child labor: evidence from poor households in Colombia

Colombia suffers from one of the longest civil conflicts in the world, which is believed to have had several consequences on the country’s economic and development performance. This study uses measures of central government deterrence effort as instruments of conflict to estimate the impact of conflict on children’s time allocation to two different types of work: housework and work performed outside the household for poor families living in small municipalities in Colombia. I find that conflict significantly increases the amount of time children allocate to work. Both housework, for girls, and work outside the household, for boys, increase with Guerrilla attacks. However, the later effect is the opposite for Paramilitary attacks.

Poor people and risky business

We try to explain why economic conflicts and illegal business often take place in poor countries. We use the concept of subsistence level of consumption (d) and assume a regular concave utility function for consumption levels higher than d. For consumption levels lower than d utility is constant and equal to zero. Under this framework poor agents are risk-lovers. This result helps to explain why economic conflicts are more likely to appear in poor economies and why poor agents are more willing to undertake illegal business.

Financial protection for the poor in Colombia: the effects of a subsidized health insurance scheme

Financial protection is one of the objectives of health systems, which protects poor households from falling into poverty as a result of health care related expenses. Expanding prepayment schemes to the poor is difficult in developing countries because labor is largely informal. Providing health care free-at-point-of-service does not adequately target spending on the poorest, but occupation- or community-based schemes have also inherent limitations to achieve universal coverage. Colombia adopted a government-subsidized health insurance scheme (SHI) strategy. The political debate about increasing SHI enrollment needs evidence about the effectiveness of this scheme regarding financial protection. This study runs a four-part model to estimate the effect of SHI on out-of-pocket expenses by the poor that are currently uninsured, if they were enrolled in the SHI. The results show a 43% and 50% reduction in expenses at Bogotá and national level respectively, which confirms the effectiveness of SHI as a financial protection tool.

Gender differences in time allocation of poor children in Colombia

This paper studies the effect of credit constraints and constraints on transfers between parents and children, on differences in labor and schooling across children within the same household, with an application to gender. When families are unconstrained in these respects, differences in labor supply or education are driven by differences in wages or returns to education. If the family faces an imperfect capital market, the labor supply of each child is inefficient, but differences across children are still driven by comparative advantage. However, if interfamily transfers are constrained so that parents cannot offset inequality between their children, they will favor the human capital accumulation of the more disadvantaged child -generally the one who works more as a child. We use our theory to examine the gender gap in child labor. Using a sample of poor families in Colombia, we conform our predictions among rural households, although this is less clear for urban households. The gender gap is largely explained by the wage gap between girls and boys. Moreover, families with the potential to make capital transfers to adult children (e.g. those with large animals), can compensate adult sons for their greater child labor and reduced educational attainment. In such families, as predicted, the male/female labor gap is greater.

Pulsioximetría de pacientes en hemodiálisis, de la unidad de terapia renal – fundación cardioinfantil, análisis para establecer recomendaciones

Introducción. En Colombia, el 80% de los pacientes con enfermedad renal crónica en hemodiálisis tienen fístula arteriovenosa periférica (FAV) que asegura el flujo de sangre durante la hemodiálisis (1), la variabilidad en el flujo de sangre en el brazo de la FAV hacia la parte distal, puede afectar la lectura de la oximetría de pulso (SpO2) (2), llevando a la toma de decisiones equivocadas por el personal de salud. El objetivo de este estudio es aclarar si existe diferencia entre la SpO2 del brazo de la FAV y el brazo contralateral. Materiales y métodos. Se realizó un estudio de correlación entre los valores de SpO2 del brazo con FAV contra el brazo sin FAV, de 40 pacientes que asistieron a hemodiálisis. La recolección de los datos se llevó a cabo, con un formato que incluyó el resultado de la pulsioximetria y variables asociadas, antes, durante y después de la hemodiálisis. Se comparó la mediana de los deltas de las diferencias con pruebas estadísticas T Student – Mann Whitney, aceptando un valor significativo de p < 0,05. Resultados. No se encontraron diferencias estadísticamente significativas de la SpO2 entre el brazo con FAV y el brazo sin FAV, antes, durante y después de la diálisis, sin embargo si se apreció una correlación positiva estadísticamente significativa. Conclusiones. Se encontró correlación positiva estadísticamente significativa, donde no hubo diferencias en el resultado la pulsioximetría entre el brazo con FAV y brazo sin FAV, por lo tanto es válido tomar la pulsioximetría en cualquiera de los brazos.

Neoconservatism in the United States and the institutionalized exclusion of Poor Women

Public Assistance to the poor in the United States was always been reluctant and especially cruel to women. A society that from the outset prized Kantian principles of individual freedom over Rousseau’s notions of social contract and that was dominated by a puritanical morality saw poverty as self-made. If individuals had freedom of choice, bad outcomes were necessarily caused by bad choices. The poor had themselves to blame.
