Determinants of left ventricular mass as measured by Doppler echocardiography in pre-adolescents

This study examined factors contributing to the differences in left ventricular mass as measured by Doppler echocardiography in children. Fourteen boys (10.3 ± 0.3 years of age) and 1 1 girls (10.5 ± 0.4 years of age) participated in the study. Height and weight were measured, and relative body fat was determined from the measurement of skinfold thickness according to Slaughter et al. (1988). Lean Body Mass was then calculated by subtracting the fat mass from the total body mass. Sexual maturation was self-assessed using the stages of sexual maturation by Tanner (1962). Both pubic hair development and genital (penis or breast for boys and girls respectively) development were used to determine sexual maturation. Carotid Pulse pressure was assessed by applanation tomometry in the left carotid artery. Cardiac mass was measured by Doppler Echocardiography. Images of cardiac structures were taken using B-Mode and were then translated to M- Mode. The dimensions at the end diastole were obtained at the onset of the QRS complex of the electrocardiogram in a plane through a standard position. Measurements included: (a) the diameter of the left ventricle at the end diastole was measured from the septum edge to the endocardium mean border, (b) the posterior wall was measured as the distance from to anterior wall to the epicardium surface, and (c) the interventricular septum was quantified as the distance from the surface of the left ventricle border to the right ventricle septum surface. Systolic time measurements were taken at the peak of the T-wave of the electrocardiogram. Each measurement was taken three to five times before averaging. Average values were used to calculate cardiac mass using the following equation (Deveraux et al. 1986). Weekly physical activity metabolic equivalent was calculated using a standardize activity questionnaire (Godin and Shepard, 1985) and peakV02 was measured on a cycloergometer. There were no significant differences in cardiovascular mesurements between boys and girls. Left ventricular mass was correlated (p<0.05) with size, maturation, peakV02 and physical activity metabolic equivalent. In boys, lean body mass alone explained 36% of the variance in left ventricular mass while weight was the single strongest predictor of left ventricular mass (R =0.80) in girls. Lean body mass, genital developemnt and physical activity metabolic equivalent together explained 46% and 81% in boys and girls, respectively. However, the combination of lean body mass, genital development and peakV02 (ml kgLBM^ min"') explained up to 84% of the variance in left ventricular mass in girls, but added nothing in boys. It is concluded that left ventricular mass was not statistically different between pre-adolescent boys and girls suggesting that hormonal, and therefore, body size changes in adolescence have a main effect on cardiac development and its final outcome. Although body size parameters were the strongest correlates of left ventricular mass in this pre-adolescent group of children, to our knowledge, this is the first study to report that sexual maturation, as well as physical activity and fitness, are also strong associated with left ventricular mass in pre-adolescents, especially young females. Arterial variables, such as systolic blood pressure and carotid pulse pressure, are not strong determinants of left ventricular mass in this pre-adolescent group. In general, these data suggest that although there is no gender differences in the absolute values of left ventricular mass, as children grow, the factors that determine cardiac mass differ between the genders, even in the same pre-adolescent age.

Temple Grandin fonds, 1974-2006 (non-inclusive)

Temple Grandin was born in Boston, Massachusetts on August 29,1947 to Richard Grandin and Eustacia Cutler. She was diagnosed with autism at age 2. She suffered from delayed speech development and did not begin to speak until the age of 4. Temple’s mother defied the doctors and kept her out of institutions. Temple was given speech therapy as well as an intensive education. Her high school science teacher and her aunt on a ranch in Arizona inspired Temple to continue her studies and pursue a career as a scientist and livestock equipment designer.She graduated from Hampshire Country School (a boarding school for gifted children) in Ridge, New Hampshire in 1966, and earned a bachelor’s degree in psychology from Franklin Pierce College in 1970. In 1975, she received a master’s degree in animal science from Arizona State University and then a doctoral degree in animal science from the University of Illinois in 1989. She is currently a professor at Colorado State University. Dr. Grandin is one of the world’s leaders in the design of livestock handling facilities. She has done extensive work in design of handling facilities for animals and has developed animal welfare guidelines for the meat industries. Dr. Grandin is a past member of the board of directors of the Autism Society of America. She lectures to parents and teachers throughout the U.S. on her experiences with autism. She makes the case that the world needs people on the autism spectrum: visual thinkers, pattern thinkers and verbal thinkers. Some of Temple Grandin’s books include: Animals Make Us Human, Animals in Translation, The Way I See It, The Autistic Brain, and Different…Not Less. In 2010, a movie entitled “Temple Grandin” starring Clare Danes was released. The movie was based on Grandin’s own writings. Temple Grandin is an expert on animal behavior, a bestselling author, and an autism activist. In 2010, she was listed in the “Heroes” category in the “Time” list of the world’s 100 most influential people. She has received numerous awards including an honorary doctorate from McGill, the University of Illinois and Duke University. Temple Granin is a philosophical leader of both the animal welfare and autism advocacy movements. sources: http://www.templegrandin.com/ http://en.wikipedia.org/wiki/Temple_Grandin

Letter - Lieut A. Watson Sime to Col. F.C. McCordick

A letter from Lieut. A. Watson to Col. F.C. McCordick dated only July 3rd. The letter reads "My dear Col. McCordick, If you haven't already heard, you will be surprised to get this letter from me - in Germany. It happened at that awful slaughter - the 3rd battle of Ypres, & even now when I think of it all, I doubt my reality of existence. Everything was O.K at 730am on the 2nd - a little morning hate in the way of trench mortars, that was all. I had just visited a few of my guns & had passed Gen.s Mercer & Williams & their aides, Lyman Gooderham and Fraser (two latter at this camp) on the way to the -- C.M.R Bn. Head Quarters when the storm broke. It last for 5 hours & by the time the Germans came over there were few left to oppose them. By a miracle, the 15 yard bay of the front line, where I was with 6 others, was not levelled like all the rest of the line & we did our best with rifle & bomb. I got a crack on the head & 3 hours later I found myself in a waterfilled shell hole. By night I tried to crawl back & through, but at dawn was caught. Am very comfortable here & glad to have company of Col. Usher, Capt. Light Bourne, Capt. Frank Park M.O. -- CMR) & about 20 other Canadians. Hope all is well with you & 35 - Good luck & best regards to all. A. Watson Sime, Lieut. Haus 62-B OFFIZIER-KRIEGSGEFANGENLAGER Gutersloh.
