From a review of medical licensing: By almost all accounts, the quality of services consumers get from non-physician clinicians is at least on par with what they would get from a physician performing the same services. Dozens of peer-reviewed studies compare outcomes in situations where patients are treated by a physician, a physician assistant, or an advanced practice nurse. Outcomes appear similar [15] - an important factor, considering that non-physician clinicians can provide many services ...

One in every 4 million children suffers from a genetic disorder called progeria that causes them to age prematurely — developing wrinkled skin and baldness before the age of 10, and usually dying of heart disease or stroke by puberty. The disease has always intrigued researchers interested in unlocking the genetic key to aging. Now it looks like a group of geneticists at the National Human Genome Research Institute in Maryland may have found a ...

One of the difficult things about having a career in medicine is that reputation is paramount. It is quite precious and is easily shattered. There are not many industries where interpersonal interaction is more important. From interactions between a provider and his patients, nurses, ancillary staff, and other providers, the professional reputation of a doctor is made. Sometimes it is fair, sometimes it is not. It’s an industry where subjective opinions of others dictates the ...

Last night, the Annals of Improbable Research held its 18th annual Ig Nobel Prizes. The prizes are awarded for scientific and social achievements "that first make people laugh, then make people think." And this year’s winners include studies on puzzle-solving slime molds, the spermicidal capabilities of Coca-Cola, and the economics of ovulating strippers. The prizes were awarded in a ceremony at Harvard University’s Sanders Theater in ten areas: Nutrition: Massimiliano Zampini and Clark Spence for ...

Scientists studying decades-old tissue samples from African hospital samples have found a preserved specimen of HIV that let them estimate when the virus first evolved: Using a technique called molecular clock analysis, they were able to plot the two viral sequences’ evolutionary path back in time to determine when they diverged. They concluded the strains evolved from a common ancestor that emerged in Africa near the beginning of the twentieth century around 80 years before ...

Baxter released the first antimicrobial luer IV connector, dubbed V-Link, earlier this year, a device known to be effective against MRSA, Pseudomonas aeruginosa and Enterobacter cloacae. The V-Link connector employs an antimicrobial silver coating Baxter calls VitalShield. The VitaShield coated connector has been shown to kill 99.9% of pathogens that can cause IV related bloodstream infections. Today, Baxter received FDA clearance to expand their labeling, based on confirmation of device's ability to combat three additional ...

Worried that you might have Multiple Sclerosis but are too lazy to go to the doctor to check and see? Well, you're an idiot, but your laziness may soon be, if not rewarded, at least not punished thanks to the work of some researchers at the University of Leeds. They've developed new biosensor technology that makes it possible for a handheld device to check for a number of different diseases in under 15 minutes. This ...

ChazeFroy writes "A new study estimates that the AIDS virus, HIV, started to circulate in the human population between 1884 and 1924, with a more focused estimate at 1908. This is much earlier than the previously-held estimate of 1930. 'The new result is "not a monumental shift, but it means the virus was circulating under our radar even longer than we knew," says Michael Worobey of the University of Arizona, an author of the new ...

A Japanese engineer believes he has invented a practical single use needle-free drug injection device that comes preloaded with medicine, and avoids the process of drawing a drug from an ampule into a separate injection device for delivery.

上周，我在网上看台湾TVBS电视台的节目《健康2.0》。一个医生在里面说，很多疾病都与饮食结构有关，所以不能放纵自己随便吃东西，平时就要养成健康的饮食习惯。接着，他说了一些饮食原则，我觉得很有道理，就抄了下来。 饮食结构 人体每天摄入的食物中，按重量计算，60%应该是碳水化合物，30%是蛋白质，10%是脂肪。 碳水化合物 碳水化合物分为“低纤维碳水化合物”和“高纤维碳水化合物”两大类。 应该多食用“高纤维碳水化合物”（如豆类、薯类、蔬菜、水果），避免仅仅食用“低纤维碳水化合物（如淀粉、精加工谷物、糖类和甜味剂）。 原因是： （1）”低纤维碳水化合物“会迅速被身体转化为单糖，导致血糖水平快速升高，长此以往不利于健康。 （2）”高纤维碳水化合物“消化得比较慢，这就使体内血糖水平不会升高得太快，而且纤维会促进消化系统蠕动，减慢其对热量的吸收。 蛋白质 蛋白质按照来源分为“植物性蛋白质”和“动物性蛋白质”两大类。 “动物性蛋白质”包括奶制品（牛奶）、肉制品（牛肉、羊肉、猪肉、禽肉）、蛋类、鱼、虾等。 “植物性蛋白质”包括大豆类（黄豆、大青豆和黑豆）、干果类（芝麻、瓜子、核桃、杏仁、松子）等。 每日30%的蛋白质摄入中，建议20%为“植物性蛋白质”，10%为“动物性蛋白质”。 脂肪 脂肪分为“动物性脂肪”和“植物性脂肪”两大类。前者在常温下呈固态，后者在常温下呈液态，又被称为“油脂”。 “动物性脂肪”主要来自动物。但是除了内脏以外，各种畜肉中脂肪含量并不高（10%），鱼肉中脂肪含量尤其低（5%）。蛋黄中脂肪含量为30%，蛋清中基本不含脂肪。 “植物性脂肪”主要来自坚果类植物，含量最高可达50%左右。米、面、蔬菜、水果中含量很少。 每日10%的脂肪摄入量中，来自“植物性脂肪”的比重越大越好，尽量避免摄入“动物性脂肪”，尤其不要食用油炸的脂肪食品。 =============== 再说一件其他的事情。 上个星期，我在《关于宋以朗》一文中，感叹他书房中竟然有那么多书。今天，宋先生回复了。 他承认自己确实读过很多书，在某些领域甚至将所有已出版的书都读了。但是，他问了一句”那又怎么样呢？“，回答是”Nothing“（毫不重要）。他说，多读书完全是因为工作的需要，对于人生根本不会造成任何区别。（There is nothing so superior about reading many books. You have to trust me on that. The more I read, the more I am confident about this assertion.） =============== UPDATE（2008.10.01）： 不好意思，我理解错了宋先生的原意。他说的是”多读书没什么了不起，并不代表高人一等“，而不是我上面的翻译”对于人生根本不会造成任何区别“。谢谢Touch网友的指出，并向宋先生致歉，本人非常汗颜。 （完）

A 13-year-old Indian girl named Twinkle Dwivedi has a medical condition that baffles doctors: she bleeds through her skin without being cut or scratched! Twinkle Dwivedi, 13, has a strange disorder which means she loses blood through her skin without being cut or scratched. She has even undergone transfusions after pints of it seeped through her eyes, nose, hairline, neck and the soles of her feet. Sometimes her condition is so bad she wakes up ...

1. Researchers have created healthy stem cells from adult cells--no embryo required and no side effects.Until now, however, creating iPS [induced pluripotent stem] cells without integrated viruses had been a major hurdle for stem-cell researchers. Although Hochedlinger has overcome that hurdle, he says there is still some distance to travel. While retroviral techniques allow scientists to turn about one in every 1,000 skin cells into an iPS cell, the adenovirus is far less efficient: only ...

They say the fastest way to a man's heart is through his stomach, but as Pyng Medical Corporation likes to point out, not if the man is in cardiac arrest! Pyng is a Richmond, B.C. based life-sciences company whose mission is "Saving lives by saving time through innovation in resuscitation." If the military medics and physicians I work with are right (and I think they are), Pyng is certainly living up to their goals and ...

According to Modern Healthcare's daily IT e-newsletter today, Cardinal Health announced it will, "spin off its clinical and medical products business into a separate, publicly traded company." In what looks ...

Psst, needlephobics! (You know who you are!) Are you afraid of shots? Investor Yoshio Oyama has invented something for you: a convenient needle-free syringe that use air pressure to deliver drugs. Yoshio’s system is called Mother’s Kiss, and National Geographic News has the video clip: Link

hackingbear writes "Wired, citing a paper published in Science magazine, reports that Harvard scientists may have found a safer way of giving a flake of skin the biologically alchemical powers of embryonic stem cells by turning adult cells into versatile, embryonic-like cells without causing permanent damage. The technique involves 'adding cell-reprogramming genes to adenoviruses, a type of virus that infects cells without affecting their DNA.' Four-month trials on mice demonstrated that the resulting stem cells ...

The eye is a delicate thing. Most ocular implants that get too hands-on with your squishy sightballs cause rejections problems, but a new implant developed by the Boston Retinal Implant project shrinks the components significantly, allowing your eye to take on its cyborg enhancements without casting them off violently as unwelcome invaders. For people with retinal diseases like acute macular degeneration or retinitis pigmentosa, vision is impared because the retina's photo-sensing cells become unreceptive to ...
