The different parts of a health care system have different focus. A hospital’s stroke(中风) unit monitors blood flow in the brain. The cardiac unit is interested in that same flow, but through and from the heart. Each collection of equipment and data is effective in its own field. Thus, like the story of blind men feeling an elephant, modern health care offers many parate pictures of a patient, but rarely a uful united one.
小学数学小论文On top of all this, the instruments that doctors u to monitor health are often expensive, as is the training required to u them. That combined cost is too high for the medical system to scan regularly, for early signs of illness, so patients are at risk of heart dia or a stroke.
An unusual rearch project called AlzEye, run by Moorfields Eye Hospital in London, in cooperation with University College, London (UCL) , may change this. It is attempting to us
e the eye as a window through which signals about the health of other organs could be discovered. The doctors in charge of it, Siegfried Wagner and Pear Keane, are studying Moorfields’ databa of eye scans, which offers a detailed picture of the health of the retina (视网膜).
The project will go a step further：With the information about other aspects of patients' health collected from other hospitals around England, doctors will be able to look for more accurate signs of dia through eye scans.
The Moorfields data t has lots of linked cas to work with—far more than any similar project. For instance, the UK Biobank, one of the world’s leading collections of medical data about individual people, contains 631 cas of a “major cardiac adver event”. The Moorfields data contain about 12, 000 such. The Biobank has data on about 1, 500 stroke patients. Moorfields has 11, 900. For the dia on which the Moorfields project will focus to start with dementia, the data t holds 15, 100 cas. The only comparable study has 86.
Wagner and Keane are arching for patterns in the eye that show the emergence of dia elwhere in the body. If such patterns could be recognized reliably, the potential impact would be huge.

Did you know that the average child has heard the word “no” over 20,000 times before they turn the age of three? Ironically, it is also around this time that children begin to develop enough personal character to refu to obey. The “terrible twos” are categorized by a lack of understanding. Somewhere between three and four, children begin to acquire the skills to reason. It is during this time they watch how other children and adults reason. If we’re not careful, the children will watch us model a world of “NOs”.
By the time a person turns eighteen, how many times have they been told no? I haven’t found any studies that even attempted to track this statistic, but I’m sure if the number is 20,000 by three, then at eighteen that number has multiplied. You can do the math.
Anyway, I think I know why we say no. We say no to protect. We say no to direct. We say no to stop potential confusion. However, do we sometimes say no just for the sake of sayi
ng no? Do we say no becau we have internalized(内在化) all of the “NOs” we’ve heard over the years and we feel it is finally our time to say no to someone el?
The internalized NO can damage the growth process of dreams in infancy as quickly as it can weaken a three-year-old. And we wonder why we run into people with big, un-accomplished dreams who have a bit of a chip on their shoulder. They have to take on the 20,000 NOs. However, the thing that keeps them going is the possibility of the power of one YES! Just as it only takes one book to make a writer a Pulitzer Prize Winner, it only takes one word to change the cour of your day. That word is YES!
