Abstract: En el 2008, en el marco del Plan Nacional de Promoción de la Salud y del Plan Comunal de Promoción de la Salud se priorizan acciones para abordar la obesidad escolar interviniendo con la Estrategia Global contra la Obesidad las escuelas con los más altos índices de obesidad a nivel comunal, focalizando en escolares de kinder (escolares entre 5-6 a os de edad) y primer a o básico (escolares entre 6-7 a os de edad). En Valparaíso, se evaluaron las acciones del Plan Comunal de Promoción de la Salud en 3 de las 4 Escuelas seleccionadas. Los objetivos de esta intervención fueron; 1) evaluar el estado nutricional de los ni os/ni as de los niveles participantes; 2) recopilar antecedentes sobre conocimientos y conductas asociadas a la alimentación y nutrición y estilos de vida en los escolares de kinder y primer a o básico y 3) identificar dificultades y fortalezas que enfrentan la implementación de las políticas sanitarias a nivel local. Se realizó un estudio descriptivo, dise o no experimental, muestra intencionada no aleatoria. La muestra incluyó a 267 escolares. Resultados; se detectó 18,8% obesidad en el nivel de transición mayor y 27% en el primer a o básico evaluados según Normas Técnicas del Ministerio de Salud de Chile (MTNSAL) en base a la referencia de la OMS 2006; para evaluar conocimientos y conductas los autores elaboraron y aplicáronlos instrumentos "Caritas" y "Colaciones más saludables". Se observó un 77% y 87%; y 90% y 64% de asociaciones correctas para conocimientos y conductas, respectivamente. Facilitadores; trabajo intersectorial y valoración desde educación; obstaculizadores; acciones desfasadas que alteran la planificación curricular de las escuelas. Las cifras de malnutrición por exceso y la dificultad para revertir esta realidad, requiere avanzar en identificar conocimientos y conductas alimentarias nutricionales en la población.

Abstract: Antecedentes: Numerosos estudios se alan la presencia de síntomas compatibles con trastornos de la conducta alimentaria en estudiantes de nutrición y nutricionistas. Objetivo: Estimar la presencia de sintomatología relacionada con desórdenes alimentarios en estudiantes de sexo femenino de la carrera de Nutrición y Dietética de la Universidad de Valparaíso. Material y Métodos: La muestra constó de 123 estudiantes que cursaban entre primer y cuarto a o de la carrera, con una media de edad de 20 a os 9 meses a las que se les aplicó el Inventario de Trastornos Alimentarios (EDI) y el Test de Actitudes Alimentarias (EAT-40). Resultados: Las estudiantes de Nutrición y Dietética tuvieron un riesgo similar (15%) de padecer patologías alimentarias que otros universitarios y el estado nutricional no se asoció al riesgo de desarrollarlas. Las sintomatologías más prevalentes en el grupo de riesgo según el EDI fueron insatisfacción corporal (p=0,01), motivación por la delgadez (p=0,01) y perfeccionismo (p=0,05). Se detectó una mayor tendencia hacia la presencia de sintomatología anoréctica en relación a la bulímica. Conclusión: Los hallazgos obtenidos contribuyen al conocimiento sobre los cuadros alimentarios, patologías que actualmente se encuentran en alza, y en grupos que la literatura designa como vulnerables Background: Several studies report eating disorder symptoms among nutrition and dietetic students and among dieticians.

Abstract: aerobic exercise promotes beneficial effects on the prevention and treatment of diseases such as arterial hypertension, atherosclerosis, venous insufficiency, and peripheral arterial disease. β-adrenergic receptors are present in a variety of cells. in the cardiovascular system, β-adrenergic receptors promote positive inotropic and chronotropic response and vasorelaxation. although the effect of exercise training has been largely studied in the cardiac tissue, studies focused on the vascular tissue are rare and controversial. this review examines the data from studies using animal and human models to determine the effect of physical exercise on the relaxing response mediated by β-adrenergic receptors as well as the cellular mechanisms involved in this response. studies have shown reduction, increase, or no effect of physical exercise on the relaxing response mediated by β-adrenergic receptors. thus, the effects of exercise on the vascular β-adrenergic sensitivity should be more deeply investigated. furthermore, the physiopathology of the vascular system is an open field for the discovery of new compounds and advances in the clinical practice.
Modelling the Impact of Stages of HIV Progression on Estimates  [PDF]

Advances in Infectious Diseases (AID) , 2015, DOI: 10.4236/aid.2015.53012
Abstract: HIV/AIDS is a public health problem especially in sub-Saharan Africa where majority of infections and deaths occur. Despite the large number of studies and efforts made in covering the data gap using mathematical models, little is known on how model estimates are confounded by the transmission variabilities that exist in stages of HIV progression. This work investigates the impact of including stages of HIV transmission in HIV/AIDS models. A deterministic HIV/AIDS model is developed and extended to include stages of HIV progression of infected individuals. Theoretical investigation of the models and numerical analyses indicate that the two models produce different estimates, with the model without stages producing lower estimates than the staged model. These results call for a careful consideration in evaluating the efficiency of HIV/AIDS models that are used to estimate and project the burden of HIV/AIDS disease.

Abstract: The objective of the study was to evaluate the oral acute toxicity of Brucea javanica Merril extract on both Male and Female DDY-Mice. Brucea javanica leaves have activity as a cytotoxic, anti-diarhhea, etc. Brucea javanica leaves extract was administered orally for first 24 hours at various dose levels (562.5mg/kg bw, 1125 mg/kg bw, 2250 mg/kg bw, and 4500 mg/kg bw) to determine the toxicity effects. The treatment groups were compared to the normal control. Vital organs (liver, heart, lymph, lungs, etc) and body weight were analyzed to study the toxicity. LD50 determined using Reed and Munich formula. Vital organs average weight showed no difference between control group and treatment groups from the lowest dose until the highest dose. In addition, the body weight data showed no difference between control group and treatment groups. LD50 for Brucea javanica extract using Reed and Munich formula was 1003.65 mg/kg bw. The result of the study showed that extract were categorized as “slightly toxic”.

Abstract: Our objective was to investigate the management of asthma during pregnancy by general practitioners providing shared maternity care.A pre-piloted, anonymous mail survey was sent to all general practitioners (n = 842) involved in shared maternity care at six maternity hospitals in Victoria, Australia. Respondents were asked about their perceived safety of individual asthma medications during pregnancy. Approach to asthma management during pregnancy was further explored using scenarios of pregnant women with stable and deteriorating asthma and poor medication adherence.Inhaled corticosteroids (ICS) were perceived to be the safest and were the preferred preventive medication in first trimester (74.1%), whilst leukotriene receptor antagonists were the least preferred (2.9%). A quarter (25.8%) of respondents would stop or decrease patients' ICS doses during pregnancy, even when their asthma was well controlled by current therapy. In addition, 12.1% of respondents were not sure how to manage deteriorating asthma during pregnancy and opted to refer to another health professional. Almost half the respondents (48.9%) reported encountering medication nonadherence during pregnancy.A lack of confidence and/or knowledge among general practitioners in managing deteriorating asthma in pregnancy was observed despite a good understanding of the safety of asthma medications during pregnancy, compliance with evidence-based guidelines in the selection of preventive medications, and self reported good asthma knowledge.Optimal asthma control during pregnancy is vital for the well-being of both mother and fetus. Poorly controlled asthma increases the risk of pre-term birth, low birth weight, cesarean section, stillbirth, intrauterine growth restriction (IUGR), congenital malformations (e.g. ventricular and atrial septal defects, spina bifida), small for gestational age (SGA) infants, pre-eclampsia, chorioamnionitis, low APGAR scores and gestational diabetes [1]. Fetal hypoxia, also a resu

Abstract: fumonisins are mycotoxins occurring worldwide, mainly in maize and maize-based food products, which could affect animal and human health. this paper reviews analytical methodologies for the determination of these fungal toxins in foods. it includes extraction, cleanup, derivatization procedures, detection, quantification, and confirmation procedures. initial attempts at gas chromatographic methods and thin layer chromatography were supplanted by liquid chromatographic methods, mainly performed with fluorometric detection, or mass spectrometry detection, enabling the analysis of polar and thermolabile chemicals without chemical derivatization, which results in lower limits of detection. alternative methods, such as enzyme linked immunosorbent assay or zone capillary zone electrophoresis, are also described.
