Abstract: background: waist to height ratio and ultrasensitive c-reactive protein are predictors of the presence of the metabolic syndrome in children. aim: to determine the proportional risk of metabolic syndrome component clustering in children, using waist to height ratio and ultrasensitive c-reactive protein. material and methods: anthropometric measures, blood pressure, fasting serum lipid profle, blood glucose and ultrasensitive c-reactive protein were determined in 209 children aged 11.5 ± 2 years (50% females). the presence of the metabolic syndrome as a function of waist to height ratio and c-reactive protein was modeled using logistic regression equations. the risk of clustering one, two or more components of the metabolic syndrome was calculated. results: metabolic syndrome was present in 5% of all children and 18% of those that were obese. the cut off points for waist to hip ratio and ultrasensitive c-reactive protein were 0.55 and 0.61 mg/l, respectively. for each 0.01 increment in waist to height ratio, the odds ratio of increasing one component of the metabolic syndrome was 1.2 (1.15-1.25) or 15 to 25%. the odds ratio for log-transformed ultrasensitive c-reactive protein was 1.62 (1.26-2.09). excluding waist circumference, the odds ratio of adding one or more components of the metabolic syndrome was 1.05 (1.01-1.09) per 0.01 increment in waist to height ratio, but the odds ratio for c-reactive protein was no longer significant. conclusions: waist to height ratio and ultrasensitive c-reactive protein predict the risk of clustering components of the metabolic syndrome in these children.

Abstract: Background: The prevalence of pediatric arterial hypertension (AHT) is approximately 1% to 2%. In the last tenyears, mean blood pressure levels (BP) have raised due to obesity and changes in lifestyles. Family history (FH) of AHT is a risk factor to develop AHT in children. Aim: To assess blood pressure, cardiovascular risk factors and family history in healthy children of Santiago. Material and methods: Blood pressure, family history of AHT, birth weight (BW), gestational age, puberal stage, blood glucose, serum lipids and ultrasensitive Reactive C Protein (usCRP) were analyzed, using data from a study of early markers of atherosclerosis in children. Results: Data of 112 children aged between 6-12 years was analyzed. Hypertension (BP >percentile 95) was detected in 2.7% and pre hypertension (BP in percentiles 90-95) in 3.6% ofthe sample. Children with abnormal BP had higher levels of usCRP (p <0.05) and a non significant tendency towards a higher body mass index. All hypertensive and one pre hypertensive children had FH of AHT. Eleven percent of parents, had high blood pressure. In no children, both parents were hypertensive. Children with a family history of hypertension had higher concentrations of total serum cholesterol (p <0.05). Conclusions: The abnormal prevalence of AHT found in this study is comparable to other studies. FH associated to higher levels of BP in children. Children with abnormal BP had a higher subclinical level of inflammation .

Abstract: background: among children both general and visceral obesity are associated with increased cardio-metabolic risk. the increasing prevalence of the metabolic syndrome (ms) in children and adolescents increases cardiovascular risk. studies of new clinical markers which can easily and accurately predict ms in children and adolescents are needed. aim: to compare zbmi and waist to height ratio (whr) as predictors of ms in chilean children. method: we performed a crossectional study of 618 schoolchildren, age 11 ± 2 years, 52 % females, 190 eutrophic, 174 overweight, 254 obese, from middle and low social economic strata from the santiago urban área. we determined weight, height, waist circumference, blood pressure and fasting lipids and glycemia. ms diagnosis was based on the presence of > 3 cook criteria. ms was modeled in function of whr and z score bmi, through logistic regression models. roc curves were used to compare zbmi and whr as predictors of ms. the cutoff point by youden índex was used. results: the prevalence of ms was 15%. mean zbmi was +1.22 ± 0.90 and whr 0.52 ± 0.07. cutoff point for ms were: whr 0,55 (sensitivity 72%, specificity 70%)andzbmi: 1.76 (sensitivity 71%, specificity 74%). conclusions: both whr and zbmi similarly predicted cardio metabolic risk in children and adolescents. the greater feasibility of calculating whr makes it a good tool for defining risk in this group. a cutoff point >0.55 might be a good predictor of ms in children and adolescents .

Abstract:
Observations of the Crab Nebula with Early HAWC Data
Francisco Salesa Greus,for the HAWC Collaboration
Physics , 2015,
Abstract: The High Altitude Water Cherenkov (HAWC) Observatory is a TeV gamma-ray detector, completed in early 2015. HAWC started science operations in August 2013 with a third of the detector taking data. Several known gamma-ray sources have already been detected with the first HAWC data. Among these sources, the Crab Nebula, the brightest steady gamma-ray source at very high energies in our Galaxy, has been detected with high significance. In this contribution I will present the results of the observations of the Crab Nebula with HAWC, including time variability, and the detector performance based on early data.

Estudios Geologicos , 2006, DOI: 10.3989/egeol.0662110
Abstract: The current work deals with the morphological analysis of the occlusal surface of the cheek teeth of several Anchitherium species from 8 Aragonian localities, most of them from the Madrid basin. This analysis is based in predefined land-marks on the occlusal surface of the teeth, located on the main cusps, and their comparison among the different species, in order to test if there are significant differences in the disposition of cusps. This kind of study had not been previously realised with large herbivores, thus being a first approximation to the use of this methodology in this group. Se realiza un análisis morfológico de la superficie oclusal de la dentición yugal superior e inferior de varias especies del género Anchitherium procedentes de otros tantos yacimientos del Aragoniense, principalmente de la cuenca de Madrid. Dicho análisis se basa en la toma de land-marks predefinidos sobre la superficie del diente (situados sobre las cúspides principales) y su comparación entre especies, para conocer si existen diferencias significativas en cuanto a la disposición de las cúspides entre las distintas poblaciones de este équido fósil. Este tipo de análisis con land-marks nunca antes había sido realizado con grandes herbívoros fósiles y, por ello, constituye una primera aproximación al uso de esta metodología en dicho grupo.

Abstract: blood pressure (bp) is a vital sign routinely obtained in adult physical examination. this is not the case in children; therefore, high blood pressure in children is frequently not diagnosed. it should be measured with adequate equipment according to age and height of the child, considering that bp values increase under physiological conditions. arterial hypertension is defined in percentiles for age, gender and height. three categories can be established: normal bp, pre-hypertension and hypertension. clinical studies have determined that the younger the child, the probability of secondary hypertension increases, usually of renal origin. genetic and metabolic risk factors have been identified intrauterine; this "fetal programming" is related later in life with the onset of high blood pressure. arterial hypertension evolves without symptoms for long periods of time, making more relevant a complete physical examination that includes bp. the hypertensive patient must be approached by age, clinical history, physical examination and bp values, followed by a laboratory work-up. complementary studies including bp ambulatory monitoring are being used with increasing frequency in the pediatric population, allowing a big number of bp readings during diary activities of the child. arterial hypertension treatment in pediatrics begins with the prevention of known risk factors, encouraging a change of lifestyle for the child and his/her family. drug treatment must be reserved after secondary causes have been corrected and lifestyle modifications did not work out. pharmacological treatment must be indicated individually, its efficacy monitored and potential adverse effects assessed. still at an experimental stage, antihypertensive vaccination modifying the renin-angiotensin system is being studied

Abstract: a poliuric syndrome (ps) is suspected when the urinary volume exceeds by 2 or 3 times the urinary volume expected for the child?s age or when after dehydration or fluid restriction an adequate urinary concentration is not produced. the volume and osmolarity of the organic fluids are precisely regulated by the activity of adh, which regulates the water permability of the distal tubules and collecting ducts. ps is classified into 2 groups: 1) low plasma adh levels (central cdi or neurogenic diabetes insipidus, and primary polydipsia and 2) those with normal plasma adh (osmotic diuresis and nephrogenic diabetes insipidus ndi). the diagnosis is confirmed by the deprivation test, if the urine density and osmolarity remain low and the urine volume is not decreased, the diagnosis of cdi is considered. the vasopressin test distinguishes cdi from ndi, an increase is seen in the osmolarity and urinary flow decreases in cdi, whereas a lack of response indicates ndi. treatment of cdi consists in hormonal replacement, while that of ndi consists in reducing protein and calorie intake, allowing the free intake of water, in addition to the use of thiazide diuretics and non-steroidal anti-inflammatories
