風險高.醫病糾紛多 婦產科醫生減
公視新聞網 /醫療 婦產科醫師人力十分吃緊!衛生署原本預定在今年1月試辦生育風險基金,一旦生產過程發生產婦或嬰兒無法預期之重殘、死亡,病家可獲最高200萬元補償,希望能降低醫病糾紛,讓年輕婦產科醫師回流,但這個政策如今卻面臨難產,今天婦產科醫學會呼籲政府,應落實婦幼政策,否則未來台灣將會沒有婦產科醫師。帶著眼鏡,長相斯文,他是花蓮玉里榮民醫院婦產科醫生鄭吟豪,因為得隨時待命,壓力太大,加上當地只有兩位婦產科醫師,另一位又將在六月底調職,鄭醫師再也支撐不住只好向醫院請了兩星期的假。
==101.5.31醫生鄭吟豪== 從去年11月到現在7個月 都是我一個人在這邊看診 及接收住院及手術婦產科醫師荒到底有多嚴重?根據婦產科醫學會的統計,近10年來,婦產科人力成長率只有16%,平均年紀達54歲,目前全國40歲以下的婦產科醫生只有377位,有80%的年輕醫生每個月接生不到10個。風險高、醫病糾紛多、健保給付制度及經濟誘因又不夠,都是造成人力萎縮的原因。衛生署原本預定在今年1月試辦生育風險基金,一旦生產過程發生產婦或嬰兒無法預期之重殘、死亡,病家可獲最高200萬元補償,但此政策如今卻面臨難產命運。
==婦產科醫學會理事長 謝卿宏== 這個生育風險補償條例本身 可以來做一個初步的 計畫來研究說 到底醫師負多少責任 讓我們根據以後可以在 施行醫療事故補償的時候 可以有一個依據 這整個案子送到行政院之後 卡了7、8個月 那我們婦產科醫學會的立場來說 我們非常的痛心婦產科醫學會表示,已經有部份產科醫生說,將在龍年結束後,退出產科的行列,因此呼籲政府,應落實婦幼政策,否則未來台灣將會面臨沒有婦產科醫師接生的窘境。 (2012-06-17 12:00)中晝新聞

Why are so many women starting the menopause before 40?
By JUDITH KEELING PUBLISHED: 22:49 GMT, 18 June 2012 | UPDATED: 22:49 GMT, 18 June 2012 When Amanda Warne's periods stopped at the age of 21, doctors put it down to stress and over-training following an intensive diet and exercise regimen. For the next four years she suffered terrifying mood swings and depression and paid countless visits to her GP and a specialist — while a series of blood tests revealed see-sawing hormone levels.Finally, doctors concluded the sporty student had suffered a premature menopause. 'Some days I could barely crawl out of bed. I felt as though I was going mad,' said Amanda Warne (now aged 33) of her menopause, which began at just 21 Blood tests showed her levels of key hormones were such that she had been through the menopause — and it wasn't clear why. 'I couldn't believe it,' says Amanda.'I was studying at the London College of Fashion and was with my first boyfriend, the love of my life, who was desperate for children. 'He told me bluntly he knew he wouldn't be able to stay with me for ever because his desire for children would always outgrow the love he had for me.'I became an insecure wreck and felt worthless.'
More... Are statins worth the side-effects for women? They're the heart wonder drugs that help millions but many are left exhausted... Psoriasis sufferers who are too scared to use the steroid cream that can beat it She also found herself crippled with mood swings, depression, panic attacks and bouts of exhaustion — classic menopausal symptoms. 'Some days I could barely crawl out of bed. I felt as though I was going mad.'I knew something had really changed in my body, but no one seemed to listen,' says Amanda, now 33 and a businesswoman living in North London. Taking Hormone Replacement Therapy (HRT) improved her quality of life, but Amanda still suffers exhaustion, low libido, headaches and a tingling sensation in her head. 'I knew something had really changed in my body, but no one seemed to listen,' said Amanda (pictured aged 21) She finds the latter particularly worrying following the publication of alarming new research last week by U.S. doctors who discovered that women who go through a premature menopause are also more likely to suffer a potentially fatal brain haemorrhage, a cerebral aneurysm.This occurs when part of the artery weakens and swells.The artery can then burst and cause a stroke or death, with half of those suffering a cerebral aneurysm likely to die.And the younger a woman is when she becomes menopausal, the greater the chances of a cerebral aneurysm — Amanda went through the menopause 30 years before the average age of 51. 'I do realise I may be facing a shortened life expectancy,' she says.The new U.S. research is part of a growing body of evidence pointing to the staggering toll on a woman's overall health associated with early menopause — a concern because more women are being diagnosed with the disorder. Most scientists define a premature menopause, or premature ovarian failure (POF), as occurring when a woman's ovaries stop working before the age of 40, though some studies include women up to the age of 45. As well as cerebral aneurysm, they are also at greater risk of heart disease — they are 50 per cent more likely to die and 80 per cent more likely to suffer from heart disease than women who go through the menopause between the ages of 52 to 55.A study last year by Imperial College London found that women who had early menopause were also twice as likely to have a poor quality of life in health terms. Another study, by the Mayo Clinic in the U.S., found that affected women had a greater risk of dying early, developing heart disease, neurological disorders, including Parkinson's and Alzheimer's, psychiatric disorders and osteoporosis. Women were particularly likely to die early or develop heart disease if they'd not been taking HRT following their early menopause, said the researchers. 'These recent studies are telling us what we have suspected for some time, but until now no one has done the work to quantify it,' says Dr Kevin Harrington, a consultant gynaecologist at the Bupa Cromwell Hospital in London. Taking Hormone Replacement Therapy (HRT) improved her quality of life, but Amanda still suffers exhaustion, low libido, headaches and a tingling sensation in her head The trigger for all this is dramatically falling levels of the hormone oestrogen.'Oestrogen plays a very important role in maintaining the health of all the connective tissues in the body,' he says. 'This includes blood vessels, skin, ligaments and bones.'The deteriorating quality of the blood vessels in the brain is responsible for conditions such as strokes. Low oestrogen affects connective tissues in the eyes and mouth, too, which is why these patients are more prone to gum disease, tooth loss and cataracts. The thyroid gland can also be affected, says Dr Harrington. This is possibly because auto-immune diseases are thought to be a major cause of premature menopause.'It may be the kind of person whose body produces antibodies that attack the ovaries is also prone to producing antibodies that attack the thyroid.' This could be the case for Amanda, as she also suffers from an underactive thyroid — causing her to gain weight and feel permanently tired. But though Amanda's heart-breaking story is unusual, it's not nearly as rare as was once thought.'Premature menopause is more common than people realise,' says Nick Panay, chairman of the British Menopause Society and consultant gynaecologist at Queen Charlotte's and the Chelsea and Westminster hospitals in London.Indeed, previous estimates put the number affected at just 1 per cent, but a study last year from Imperial College London suggested as many as 6 per cent (one in 16) of women experience it. Lifestyle may be to blame. The Imperial College study found a link with smoking.Further research last year also suggested a link between premature menopause and PFCs — chemicals found in non-stick pans and food packaging. The women with the highest levels of PFCs in their body had the lowest levels of oestrogen in their blood. Genetics may play a part, too, with women more likely to go through early menopause if their mother did. However, doctors say more research is needed.Mr Panay also believes that while doctors are seeing more cases of premature menopause, this might be because the condition has previously been under-reported. Furthermore, the success in treating cancer in children, adolescents and women of child-bearing age might lie behind some cases of POF — for instance, premature menopause can be a side-effect of chemotherapy and radiotherapy.But bleak as this sounds, all experts agree that for many women serious health risks can be reduced if they're given a suitable course of HRT from the time they are diagnosed up to the age of 52. 'HRT replaces the oestrogen the woman would otherwise be producing naturally during this time — and with it the protection it affords,' says Mr Panay. Clearly early diagnosis is key, yet despite improved recognition of POF, campaigners say much more could be done. A recent British Menopause Society report noted some doctors were still unaware of the need to protect prematurely menopausal women against future illness and called for the creation of a national register of all such patients to ensure they receive correct advice and care. Campaigners are also calling for HRT to be made free of prescription charge for women who've suffered a premature menopause.'If you had diabetes you would get insulin, so why should women who have gone through a premature menopause and have a hormone deficiency have to pay?' argues Mr Panay, who is also patron of the support group Daisy Network.This is something 42-year-old Tracy Higgins, a welfare officer from Bishop's Stortford, Herts, would agree with.Tracy, who is married to Nigel, 47, went through the menopause after giving birth to her daughter Amelie, now four.She suffered Sheehan's Syndrome, where the pituitary gland in the brain becomes damaged after being starved of oxygen following severe blood loss.One of the results can be that the ovaries no longer produce eggs. 'I am pleased to be protected by HRT, but being made to pay for it is adding insult to injury,' she says.'My prescription involves two hormones, oestrogen and progesterone, so I pay double; £15 every three months.'The bill for Amanda Warne has been far steeper.She struggled to find an oestrogen replacement that didn't make her feel ill — symptoms included sore breasts, extreme bloating and exhaustion — and at one stage was spending £250 a month on a plant-based oestrogen remedy she bought online; she's stopped because of the cost. A year ago, she spent £12,000 on IVF using donor eggs after falling in love with a new partner, Greg. Unfortunately, she suffered a miscarriage at three months. The couple were subsequently told they were eligible for a free round of IVF on the NHS and waited three months for an appointment — only to be finally told no funds were available.Amanda feels that further IVF would be too expensive and take too great a toll on her emotionally and physically.'It's been a long battle for me, but there are other young women out there who may have issues with their periods that they are not getting answers to.
抗肿瘤,上海取得重大成果
2012年06月19日 海峡都市报 上海在自主产权抗肿瘤新药的研发领域获得突破,作为上海市重大科技项目,专门用于晚期肿瘤的治疗性中药新药枫苓合剂(国药准字Z20053611)在上海张江高科技园问世。"枫苓合剂"背靠上海强大的科研团队,53位中医肿瘤专家参与,采用最新的中药现代化双合提取突破性技术。专家预言,枫苓将全面替代传统的化疗药物,患者从此可以少花费,又可无毒副作用治疗肿瘤,为无法手术、不宜放化疗的晚期肿瘤病人带来生存希望。
枫苓合剂克服了传统疗法的不足为什么很多病人经手术,放、化疗后,仍因复发、转移而死亡,还有许多病人边治疗、边扩散、边转移……究其原因,手术只是对原发病灶的切除,而不能有效控制残余肿瘤细胞的复发、转移。放、化疗既杀肿瘤细胞,也杀正常细胞,造成敌我不分,玉石俱焚,常常造成"瘤消人亡"的局面。与传统的手术,放、化疗等疗法完全不同,纯中药抗肿瘤新药枫苓合剂没有任何副作用,从机体免疫内因入手,按照肿瘤的生物学特性,多步骤,多环节,从而彻底解决了传统疗法的不足,更能及时修复受损的免疫系统,迅速控制病情,缩小肿块,防止复发和转移。
枫苓合剂是如何使肿瘤缩小、消失的?
1.切断肿瘤新生血管,使肿瘤得不到营养供应而饥饿死亡。肿瘤的生长需要新生血管提供营养,并排出其代谢废物,而枫苓能阻止肿瘤新生血管的形成,同时能切断肿瘤的新生血管,使肿瘤得不到营养供应而饥饿死亡,这和人不吃饭会饿死是同样的道理。
2.激活体内抗肿瘤细胞群攻击肿瘤细胞,使肿瘤迅速凋亡。枫苓能增殖、活化体内巨噬细胞,使之更容易识别、攻击肿瘤细胞。并促进体内产生大量白细胞介素12,激活自然杀伤细胞NK,杀伤性T细胞及LAK细胞,对肿瘤展开不间断,密集式地攻击,使肿瘤细胞很快死亡、消失。
3.生成大量肿瘤坏死因子TNFa,加速溶解肿瘤细胞,使肿瘤迅速消亡。可见,新药枫苓合剂最成功之处就在于:在不知不觉中,肿瘤缩小消失了。经第二军医大学上海长海医院、上海中医药大学曙光医院、同济大学附属铁路医院及广州中医药大学附属二院等大量临床证实,该药主要针对胃、肝、食道、胰腺和肠等消化系统肿瘤的临床治疗,临床药理研究表明,对肺、鼻咽、乳腺、宫颈、前列腺等肿瘤效果非常好,许多患者使用后,肿瘤很快缩小、消失了。
枫苓已率先列入上海医保目录笔者了解到,鉴于枫苓合剂的出色效果,国家科技部、上海科委拨专款鼓励规模化生产,力争全面替代传统的化疗药物,而国家药品监督管理局也批准其为国家抗肿瘤新药,同时上海率先将其列入医保目录(医保编号Z0131200010020),在上海19家大医院肿瘤科使用,上海医保患者已早于全国其他地方患者受益。
Quintiles to invest $14 million in Shanghai regional HQ
BY LAURA OLENIACZloleniacz@herald-sun.com; 919-419-6636DURHAM – Durham based-Quintiles is investing $14 million in a regional headquarters in Shanghai to serve its business in China and in nearby Asian countries and is looking to significantly grow its workforce in China by year's end. The company manages clinical trials for pharmaceutical companies, and it also supplies capital as well as consulting and commercialization services for pharmaceutical, biotech and medical device development companies.Quintiles launched operations in China in 1997. It has offices in Beijing, Dalian and Hong Kong, as well as in Shanghai. The company is looking to "significantly" expand its lab testing capabilities in China, according to a recent news release by the company.Through a joint venture agreement, Quintiles will be working with the Shanghai Clinical Research Centre to provide lab testing services to local customers.The Shanghai Clinical Research Centre is a clinical research center in China founded in 2008. It operates as a third-party assessment and resources provider to make drug development more efficient.The collaboration follows last year's launch of Kun Tuo, Quintiles' contract research organization serving China. The organization was launched to help local and global companies get their medicines successfully registered in China. In addition, a $14 million investment in a 43,000-square-foot headquarters in Shanghai is meant to provide infrastructure to back the company's China growth strategy. The headquarters is expected to house more than 450 employees in the next five years, and is expected to be ready by 2013. Phil Bridges, a spokesman for Quintiles, said Quintiles has 350 employees in China. He didn't have any information on how many employees in Shanghai will be new, but he did say the company expects to grow to 600 employees by the end of the year."These investments and agreements demonstrate our commitment to this district and to China," said Ling Zhen, general manager for Quintiles' operations in China, in a prepared statement. "Quintiles recognizes the unique needs of our customers in China. By collaborating with SCRC in labs we can help local and international biopharma companies develop new and better medicines to serve China's enormous unmet medical needs."According to information in an email from Bridges, Asian countries such as Japan, South Korea, China and Taiwan have seen an increase in clinical trials launched in the past two years.The company has seen "very robust demand" for high-quality, low-cost lab work in China, according to the e-mail from Bridges."With the investment of, and support from Quintiles, the SCRC lab will be in an even better position to serve a bigger clientele base and to meet their increase in demand in China," his email states.

A new indicator for breast cancer relapse identified
June 19, 2012 in Cancer Researchers at the IMIM (Institut de Recerca Hospital del Mar) have proven that the absence of the 14-3-3 protein sigma in breast cancer cells is directly associated with these cells' capacity to activate the signalling of a protein complex called NF-kB, which is related to tumour progression. The activation of NF-kB in tumours was also identified as the best indicator for relapse in breast cancer patients, compared to other parameters currently used, such as the presence of affected ganglions or the tumour's size and degree. The investigators have also described a group of genes that are activated in breast cancer cells and that are also associated with a poor prognosis in other types of tumours. Previous studies had detected that the 14-3-3 protein sigma was not present in the tumours of many breast cancer patients. They have now discovered that 'the lack of this protein does not in itself establish a prognosis factor for these types of cancer, although the NF-kB complex is an essential requirement for it to remain active chronically, as it is associated with tumour invasion and metastasis or, stated differently, the progression of the tumour', comments Lluís Espinosa, study coordinator and researcher in the IMIM stem cells and cancer research group. Breast cancer is most common among women in Western countries and relapse and metastasis are the fatal consequences of this disease. Identifying the mechanisms involved in the survival of breast cancer cells and their ability to colonise other tissues are crucial issues for improving treatment. With the participation of some 100 patients, this study analysed the possible usefulness of determining the lack of the 14-3-3 sigma and/or the activation of NF-kB in tumour cells as a factor in prognosis and diagnosis, as well as for future clinical and therapeutic applications. The results obtained from this project have opened up new roads of investigation that will have to centre on identifying the pharmaceuticals that induce the expression of the 14-3-3 protein sigma in breast tumours and characterise their effect on tumour cells. They also hope to define which genes activated by the NF-kB complex are important for tumour progression in this group of patients and to study their potential as possible therapeutic targets. According to Espinosa 'This opens up the possibility of researching and employing specific therapeutic strategies for this concrete group of patients who, in principle, have bad prognoses and an especially high risk of relapse'. The study was initially led and developed at the IMIM by Dr Lluís Espinosa's and Anna Bigas' group and collaboration from researchers and doctors from the Hospital del Mar, the Jimenez Díaz Foundation, the Barcelona Institute of Biomedical Research (IRB) and Pompeu Fabra University.

Abnormal gene product associated with prostate cancer generated by unusual mechanism
June 19, 2012 in Cancer Researchers have identified a potential new pathway in prostate cancer cells by which cancer-driving gene products can be generated, according to a study published in Cancer Discovery, a journal of the American Association for Cancer Research. "Our work shows that cancers have many more tricks than we thought to generate potential cancer-driving genes or gene products," said Hui Li, Ph.D., assistant professor of pathology at the University of Virginia in Charlottesville, and a recipient of an Innovative Research Grant from Stand Up To Cancer (SU2C). The AACR is the scientific partner of SU2C. Gene fusion is a common characteristic of human cancers. In many cases, the protein products of these gene fusions, which are generated via an RNA intermediate, have a key role in the genesis of the cancer. A well-characterized example of this is the protein that drives chronic myeloid leukemia, BCR-ABL, which is generated via RNA intermediates from a fusion gene formed by chromosomal translocation — an event involving exchange of genomic DNA between two distinct chromosomes. "For many years, chromosomal translocation was considered the sole way in which single RNAs consisting of copies of parts of two genes, so-called fusion RNAs, could be generated," said Li. "We have shown that fusion RNAs can be generated without changes to DNA by a new mechanism that we are calling cis-SAGe [cis-splicing of adjacent genes]." Recently, a fusion RNA formed from parts of the SLC45A3 and ELK4 genes was identified in prostate cancer cells in the absence of any DNA alterations. Li and his colleagues confirmed in two prostate cancer cells lines that the SLC45A3-ELK4 fusion RNA could be detected even though there was no evidence of genomic DNA rearrangement. Detailed molecular analysis of the prostate cancer cell lines indicated that the SLC45A3-ELK4 fusion RNA was generated by cis-SAGe. SLC45A3 and ELK4 are neighboring genes, and cis-SAGe occurred when an RNA that crossed the boundary between the two genes was formed. The protein CCCTC-binding factor normally acts to insulate SLC45A3 and ELK4 from each other. Li and his colleagues found that levels of this protein at the gene boundary inversely correlated with the amount of SLC45A3-ELK4 fusion RNA generated, providing molecular insight into how the quantity of this fusion RNA could be regulated. A functional role for the SLC45A3-ELK4 fusion RNA in prostate cancer was suggested by two observations. First, it promoted the growth of the two prostate cancer cell lines in culture. Second, its levels in human prostate samples correlated with prostate cancer disease progression — normal prostate tissue expressed the lowest levels and prostate cancer specimens from men with metastatic disease expressed the highest levels. "These data are not sufficient to say that the SLC45A3-ELK4 fusion RNA has a causal role in prostate cancer," said Li. "But they are highly suggestive, and I am very excited that this high-risk project, which I would not have been able to pursue without the grant from Stand Up To Cancer, has uncovered what seems to be a new way in which cancer can be driven."

Diabetes May Hasten Mental Decline
Older adults with poor blood sugar control performed worse on tests of memory, thinking By Robert Preidt Monday, June 18, 2012 MONDAY, June 18 (HealthDay News) -- Older adults with diabetes and poor blood sugar control are at increased risk for greater declines in their memory and thinking abilities, a new study finds.Researchers followed more than 3,000 people without dementia, average age 74, for more than 10 years.At the start of the study, 23 percent of the participants had diabetes. Of the more than 2,300 participants without diabetes, 159 developed the condition during the follow-up period.People with diabetes at the start of the study scored lower on initial tests of their thinking skills than those without diabetes. During the follow-up, participants with diabetes showed much greater declines in mental function than those without diabetes.The study was published online June 18 in the journal Archives of Neurology.The findings support the theory that older adults with diabetes have reduced thinking and memory skills and that poor blood sugar control may be a contributing factor, said Dr. Kristine Yaffe, of the University of California, San Francisco, and the San Francisco VA Medical Center, and colleagues in a journal news release.The investigators said further research is needed to determine if early diagnosis and treatment of diabetes reduces the risk of mental decline and if good blood sugar control helps reduce the effect of diabetes on thinking and memory function.While the study found an association between diabetes and mental decline, it did not show a cause-and-effect relationship.SOURCE: Archives of Neurology, news release, June 18, 2012
Implanted device delivers genetically engineered neurotrophic factor directly to the brain
Published on June 19, 2012New approach reported in Restorative Neurology and Neuroscience Studies suggest that neurotrophic factors, which play a role in the development and survival of neurons, have significant therapeutic and restorative potential for neurologic diseases such as Huntington's disease. However, clinical applications are limited because these proteins cannot easily cross the blood brain barrier, have a short half-life, and cause serious side effects. Now, a group of scientists has successfully treated neurological symptoms in laboratory rats by implanting a device to deliver a genetically engineered neurotrophic factor directly to the brain. They report on their results in the latest issue of Restorative Neurology and Neuroscience.Researchers used Encapsulated Cell (EC) biodelivery, a platform which can be applied using conventional minimally invasive neurosurgical procedures to target deep brain structures with therapeutic proteins. "Our study adds to the continually increasing body of preclinical and clinical data positioning EC biodelivery as a promising therapeutic delivery method for larger biomolecules. It combines the therapeutic advantages of gene therapy with the well-established safety of a retrievable implant," says lead investigator Jens Torn-e, NsGene A/S, Ballerup, Denmark.Investigators made a catheter-like device consisting of a hollow fiber membrane encapsulating a polymeric "scaffold," which provides a surface area to which neurotrophic factor-producing cells can attach. When implanted in the brain, the membrane allows the neurotrophic factor to flow out of the device, as well as allowing nutrients in. Dr. Torn-e and his colleagues used the neurotrophic factor Meteorin, which plays a role in the development of striatal projection neurons, whose degeneration is a hallmark of Huntington's disease. The scientists engineered ARPE-19 cells to produce Meteorin and used those that produced high levels of Meteorin in their experiment.

LDL particles may be a more accurate measure of early-stage atherosclerosis
Published on June 19, 2012LipoScience, Inc., an in vitro diagnostic company advancing patient care by developing high value proprietary clinical diagnostic tests using nuclear magnetic resonance (NMR) technology, today announced publication of a clinical study in the current issue of Atherosclerosis suggesting that low density lipoprotein (LDL) particles may be a more accurate measure of early-stage (subclinical) atherosclerosis than LDL cholesterol among retired National Football League (NFL) players."These results suggest that LDL particle number may be a more effective indicator of subclinical atherosclerosis in retired NFL players with metabolic syndrome"Researchers conducted carotid artery plaque screenings as well as traditional and specialized lipid testing on 948 retired professional football players. Carotid arteries supply oxygenated blood to the brain and a plaque buildup may narrow these arteries, which may decrease blood flow and increase the risk of a stroke. Carotid artery plaques were present in 41 percent of this population, and while various measures of cholesterol - LDL particle number, LDL cholesterol and non-HDL cholesterol - were all associated with these plaques, the link to atherosclerosis was strongest for LDL particle number.In addition, nearly twenty percent (187) of the retired players tested also had metabolic syndrome, a cluster of risk factors that occur together and increase the risk for coronary artery disease, stroke, and type 2 diabetes. In this subset of players, LDL particle number and non-HDL cholesterol were significantly associated with carotid artery plaques, whereas LDL cholesterol was not.
New method generates cardiac muscle patches from stem cells
June 19, 2012 in Cardiology A cutting-edge method developed at the University of Michigan Center for Arrhythmia Research successfully uses stem cells to create heart cells capable of mimicking the heart's crucial squeezing action. The cells displayed activity similar to most people's resting heart rate. At 60 beats per minute, the rhythmic electrical impulse transmission of the engineered cells in the U-M study is 10 times faster than in most other reported stem cell studies. An image of the electrically stimulated cardiac cells is displayed on the cover of the current issue of Circulation Research, a publication of the American Heart Association. For those suffering from common, but deadly, heart diseases, stem cell biology represents a new medical frontier. The U-M team of researchers is using stem cells in hopes of helping the 2.5 million people with an arrhythmia, an irregularity in the heart's electrical impulses that can impair the heart's ability to pump blood. "To date, the majority of studies using induced pluripotent stem cell-derived cardiac muscle cells have focused on single cell functional analysis," says senior author Todd J. Herron, Ph.D., an assistant research professor in the Departments of Internal Medicine and Molecular & Integrative Physiology at the U-M. "For potential stem cell-based cardiac regeneration therapies for heart disease, however, it is critical to develop multi-cellular tissue like constructs that beat as a single unit," says Herron. Their objective, working with researchers at the University of Oxford, Imperial College and University of Wisconsin, included developing a bioengineering approach, using stem cells generated from skin biopsies, which can be used to create large numbers of cardiac muscle cells that can transmit uniform electrical impulses and function as a unit. Furthermore, the team designed a fluorescent imaging platform using light emitting diode (LED) illumination to measure the electrical activity of the cells. "Action potential and calcium wave impulse propogation trigger each normal heart beat, so it is imperative to record each parameter in bioengineered human cardiac patches," Herron says. Authors of the study note that the velocity of the engineered cardiac cells, while faster than previous reports, it is still slower than the velocity observed in the beating adult heart. Still the velocity is comparable to commonly used rodent cells, and authors suggest human cardiac patches could be used rather than rodent systems for research purposes. The new method can be readily applied in most cardiac research laboratories and opens the door for the use of cardiac stem cell patches in disease research, testing of new drug treatments and therapies to repair damaged heart muscle.

Skin disease shares common inflammatory pathway with metabolic disorder
Published on June 19, 2012Psoriasis is an independent risk for Type 2 Diabetes, according to a new study by researchers with the Perelman School of Medicine at the University of Pennsylvania, with the greatest risk seen in patients with severe psoriasis. Researchers estimate that an additional 115,500 people will develop diabetes each year due to the risk posed by psoriasis above and beyond conventional risk factors. The research is published in the latest issue of the Archives of Dermatology, a JAMA Network publication."These data suggest that patients with psoriasis are at increased risk for developing diabetes even if they don't have common risk factors such as obesity," said senior author Joel M. Gelfand, MD, MSCE, associate professor of Dermatology in the Perelman School of Medicine. "Patients with psoriasis should eat a healthy diet, get regular exercise, and see their physician for routine preventative health screenings such as checks of blood pressure, cholesterol, and blood sugar."Psoriasis is a common inflammatory skin disease affecting over 7.5 million Americans and causes thick, inflamed, scaly patches of skin. The disease has previously been associated with increased risk of myocardial infarction, stroke, metabolic syndrome and cardiovascular mortality."This research builds on previous work demonstrating a diverse set of increased health risks for people with psoriasis," said lead author Rahat S. Azfar, MD, MSCE, adjunct assistant professor of Dermatology in the Perelman School of Medicine. "In addition to having an increased risk of diabetes, people with psoriasis are more likely to have metabolic syndrome, high triglycerides, and raised glucose levels, even if they are not overweight or have other common risk factors for these conditions. Both patients with psoriasis, especially those with severe psoriasis, and their treating physicians should be aware of the potential for systemic metabolic complications associated with this skin disease."Both psoriasis and diabetes are diseases caused by chronic inflammation. A shared pathway - TH-1 cytokines - can promote insulin resistance and metabolic syndrome, and promote inflammatory cytokines known to drive psoriasis.

Tracking America's physical activity, via smartphone
June 19, 2012 By Angela Herring in HealthStephen Intille, Associate Professor of Computer and Information Science and Health Sciences "We know that most Americans are too sedentary," said Northeastern associate professor Stephen Intille, a founding faculty member of the university's new Personal Health Informatics graduate program with dual appointments in the College of Computer and Information Science and Bouvé College of Health Sciences. "What we need is high quality information about what drives decisions about physical activity so we can design the next generation of health interventions." Toward that end, Intille has teamed up with Genevieve Dunton, an assistant professor of preventive medicine at the University of Southern California, to gather information about where, when, why and how teenagers get their physical activity. Traditional studies ask participants to place an activity monitor on their hip, which uses an accelerometer to measure motion. "What you get are data recording roughly how active a person is throughout the day, but you don't get any information other than this motion pattern," Intille explained. But in order to develop informed interventions, public health professionals also need to know things like where people are when they're exercising or sedentary, if they're with other people and what they're doing. That's why Intille and Dunton, with the support of a two-year, $450,000 grant from the National Institutes of Health, will develop and evaluate a mobile phone app that supplements the activity-monitor data. Using the location and motion technologies already embedded in mobile devices, Intille's app will determine appropriate times throughout the day to ask study participants about the contexts that are influencing their activity. "The fundamental idea is there is a relationship between the motion of your phone and the activity that you do and the use of the activity monitor." The phone will recognize periods of increased or reduced physical activity (for example, if you take it off while playing a high-impact sport or take a nap) and present questions about what a participant is doing during the "interesting" periods. "It's about creating and evaluating a tool that would help us augment the type of information that we get from standard research tools so that researchers get that additional contextual info about where and why teens are doing the activity," said Intille. Dunton explained that the higher quality data will allow researchers to better understand the relationship between physical activity, sedentary behaviors, and the risk of metabolic, cardiovascular and other chronic diseases. Intille's lab at Northeastern focuses on sensor-driven mobile health technology. Other studies to come out of it have used a similar approach, but this is the first time the app will be programmed to recognize major activity changes. "Previous studies would ask questions randomly throughout the day, but that's not a very efficient way to do it," Intille said. This is the first time the app will be programed to augment an existing research tool by recognizing major activity changes and using a game-like interface that makes it easy for teens to fill in gaps by answering carefully-timed questions. He hopes that the app will provide a valuable, low-cost tool for future studies that also investigate physical activity patterns. "In the long term, we could potentially use this same type of technology as an intervention," said Intille, who explained, for example, that users would receive positive feedback messages through the phone when the app detects that they are being physically active.

Tea drinkers may be at greater risk of prostate cancer: study
June 19, 2012 in Cancer(Medical Xpress) -- Men who are heavy tea drinkers may be more likely to develop prostate cancer, according to research from scientists at the University of Glasgow which is published in the journal Nutrition and Cancer. The study, which was led by Dr Kashif Shafique of the Institute of Health & Wellbeing at the University of Glasgow tracked the health of more than 6,000 male volunteers over a period of 37 years and discovered that those who drank more than seven cups of tea per day had a 50% higher risk of developing prostate cancer compared with non-tea drinkers or those drinking less than 4 cups per day. The Midspan Collaborative study began in Scotland in 1970 and gathered data from more than 6,000 male volunteers, all between 21 and 75 years of age. Participants were asked to complete a questionnaire about their usual consumption of tea, coffee, alcohol, smoking habits and general health, and attended a screening examination. Just under a quarter of the 6,016 men included in the study were heavy tea drinkers. Of these, 6.4% developed prostate cancer during a follow-up of up to 37 years. Researchers found that men who drank more than seven cups of tea per day had a significantly increased risk of prostate cancer compared to those who drank no tea or less than 4 cups per day. Dr. Shafique said, "Most previous research has shown either no relationship with prostate cancer for black tea or some preventive effect of green tea. We don't know whether tea itself is a risk factor or if tea drinkers are generally healthier and live to an older age when prostate cancer is more common anyway." "We found that heavy tea drinkers were more likely not to be overweight, be non alcohol-drinkers and have healthy cholesterol levels.However, we did adjust for these differences in our analysis and still found that men who drank the most tea were at greater risk of prostate cancer." Prostate cancer is the most common cancer amongst men in Scotland and between 2000 and 2010 incidence increased by 7.4%.
工研院第11度參加北美BIO生技大展
2012/06/19 駐波士頓台北經濟文化辦事處處長洪慧珠(左起)、行政院政務委員張善政、貿協駐紐約辦事處處長魏光勛,一起為「台灣生技主題館」揭幕剪綵。工研院/提供 【台北訊】「2012 BIO International Convention(BIO)」 6月18日在美國波士頓登場,台灣代表團再次發揮團隊精神,集合台灣產、官、學、研等單位,包含國科會、衛生署、科管局、超級整合育成中心(SiiC)、經濟部生醫推動小組、工研院、生技中心及多家知名台灣生技大廠,攜手於「台灣生技主題館」亮相,共同行銷台灣生技產業卓越的研發與製造能量。工研院更藉此國際生技產業年度盛事,發表「膠原蛋白支架」及「溫感水膠」兩大技術,展示工研院關鍵核心研發能量。今年「台灣生技主題館」分別以農業生技重要成果、研究機構與產學的重大生醫科研成果及卓越臨床試驗服務能量三大區塊展示,分區展出當前台灣生技研發能量及合作機會。參展單位之一的工研院,今年參展重點包含關鍵核心研發能量與承接國際醫療大廠訂單,希望藉此加速台灣產業與國際接軌。工研院自2003年開始參加此項全球最大的生技展BIO,生醫所所長邵耀華博士指出,此行以創新前瞻研發成果為重點,主推「膠原蛋白支架」及「溫感水膠」兩大關鍵核心研發能量。其中以基因重組方式開發出創新的「膠原蛋白支架」優勢,在於已可與國際大藥廠現有藥物結合,達到增加抗體、抗原親和力、降低副作用及減少使用量之目的,讓國際藥廠無需花費過多資源便可讓「老藥翻身」。不僅如此,「膠原蛋白支架」技術可與目前多款藥物做結合,有效增強藥物治療功效,達到創新藥物解決方案重要里程碑。目前已有多家國際大型藥廠表達與工研院洽談此技術合作,充分突顯國際藥廠對「膠原蛋白支架」高度重視。針對另一關鍵核心研發能量「溫感水膠」,邵耀華指出,以往醫師用藥瓶頸在於如何精準釋放藥劑,工研院有鑑醫師此需求,因而研發「可吸收性溫感水膠」載體,未來藥劑僅需搭配溫感水膠,便可達到於人體內適時適量釋放目的,醫師用藥因此將更為精準。工研院現已將溫感水膠用於髖關節搭配生長因子使用,輔助廠商搶食每年高達8.5億美元骨修補材市場,預估未來將同步應用在其餘市場,如與牙科醫師合作,用於植牙前修補骨缺損,或搭配麻醉藥劑、止血劑及各類敷材,估計未來 5年內產值上看16億美元。今年除持續讓國際了解到工研院關鍵研發核心能量外,為與國際生技大廠接軌,讓台灣生技產業得以持續升值,工研院於展中向國際展示工研院承接國際訂單能量。目前工研院已通過GMP嚴格審核標準工廠包含骨科醫療器材工廠、中草藥工廠、原料藥工廠及細胞工廠等,未來國際生技業者產品進入臨床試驗前,可藉由工研院的GMP工廠進行小量試產,為上市前做更好的準備,並與工研院現有關鍵核心研發能量相結合,共同開發下世代創新醫療器材與生技製藥產品。
診所串通養老院 詐領健保2千萬
2012-06-16 01:10 中國時報 黃文博/台南報導嘉義縣民雄地區的「成功診所」,五年來收集親友和鄰近「感恩老人養護中心」一百多人的健保卡,合計盜刷兩萬筆,再向健保局詐領診療費近二千萬元,養護中心因此每月可分到廿多萬元利益。台南地檢署偵訊後,負責人張嘉昇與任會計的姊姊林張春瓊收押,醫師林智輝廿五萬交保。 健保局台南分局去年在比對成功診所健保請領款時,發現該診所有一百多名固定病患的診療費,有異常的請領情況;但健保局派出稽查員前往了解時,竟遭到診所和「感恩老人養護中心」的惡言相向。 健保局於是列出成功診所最近二萬筆有異常的診療費了解,懷疑每筆可能詐領五百到一千元,將資料移請台南地檢署檢肅黑金專組檢察官林仲斌、劉修言偵辦。 兩位檢察官前天指揮嘉義市調查站和台南市警局到成功診所、感恩老人養護中心搜索,除查扣帳冊、病歷資料外,還發現六張本人未到診而被用來盜刷的健保卡。同時傳喚醫師林智輝、養護中心負責人張嘉昇、蔡美月夫妻,以及在診所掛號的林張春瓊。 檢調發現,林智輝從民國九十六年十月起,除收集親友健保卡外,還找上張嘉昇配合,利用張男集中保管院民健保卡機會,總共收集一百多張健保卡,輪流向健保局詐領每筆五百到一千元的診療費和醫藥費;五年來合計詐領近二千萬元,而這些被利用來詐領的民眾,好處都沒分到,養護中心每月則可分到廿多萬元。 由於林智輝已坦承部分犯行,檢方認有詐欺、偽造文書之嫌,諭令廿五萬元交保;另以有串證之虞,向台南地院聲押張嘉昇夫妻和姊姊林張春瓊,但法官只裁准收押兩姊弟,蔡美月被飭回。
腦中風治療及照護問題 健保局澄清:有給付及獎勵措施
優活健康資訊網 (2012-06-19 12:11)分享|(優活健康網記者談雍雍/綜合報導)針對有關日前媒體報導台灣腦中風學會指稱,注射腦中風藥物r-TPA不是手術,健保無給付,健保局也澄清此為錯誤訊息。缺血性腦中風是目前台灣地區最常見的腦中風型態,健保局自93年1月1日起即給付急性缺血性腦中風發病三小時內使用合成的血栓溶解藥(r-TPA,如Actilyse®),增加中風病人康復的機會或降低殘障等級。經查,98年至100年診斷為腦中風的病人中,醫療院所申報使用r-TPA藥品的人數,由724人增加至1,263人,有逐年升高之趨勢。對於急性缺血性腦中風的病人,若能儘早診斷、儘速使用r-TPA於發病3個小時內,是得到好的治療結果重要因素,因此提升各級醫院的急診品質是對於這類病患照顧的重要策略。健保局於99年1月1日起即調增檢傷分類的急診診察費支付標準,並將夜間急診診察費用加成率由2成提高為5成。並於101年5月1日公告實施的「全民健康保險急診品質提升方案」中,納入急性腦中風的急診病人,在符合健保用藥規定3個小時內診斷及完成r-TPA注射之個案給予獎勵,每個個案可以申報2,000點的獎勵,以確保病患在用藥安全的前提下,得到適當、有效的醫療照護及品質。對於腦中風病人或其他病疾病患住院治療時,按病床類別(加護病房或一般病房),每天支付住院診察費由712點至257點不等,如需要會診其他專科醫師,則支付住院會診費,而且腦中風病患住院治療期間接受本保險給付範圍內的病床費、檢驗、處置、手術或藥物治療,健保均有給付,並無文內提及「治療中風沒有健保給付,頂多會診費及中風給付與治療粉刺給付費用相同」的情事。

Published on June 19, 2012Covidien (NYSE: COV), a leading global provider of healthcare products, today announced the latest additions to its growing bariatric surgery portfolio of products and services designed to improve patient and surgeon experiences with weight loss surgery and other procedures."Bariatric surgery requires a significant amount of surgical stapling and suturing to ensure anastomotic closure"Covidien's V-Loc™ knotless suturing device is now available as a reload that works with the Company's proprietary Endo Stitch™ and SILS™ Stitch suturing devices for multi-port and single-port laparoscopic surgery. The new device can increase operating room efficiency during bariatric surgery and other procedures."Bariatric surgery requires a significant amount of surgical stapling and suturing to ensure anastomotic closure," noted Dana D. Portenier, MD, Assistant Professor of Surgery, Duke University Medical Center. "The ability to suture internal tissue laparoscopically without the need to tie knots can help surgeons shorten one of the most labor-intensive tasks performed during bariatric surgery. As an early user of the Endo Stitch device with the V-Loc reload, I've been able to perform laparoscopic suturing with greater ease and efficiency than I previously could have using traditional devices that require knots."By combining proprietary automated needle-passing technology with a knotless suturing device, the V-Loc device for Endo Stitch and SILS Stitch devices offers distinctive benefits over hand suturing and conventional automated suturing options. The V-Loc device for use with Endo Stitch has a unique barb and loop design, enabling faster suturing by eliminating the need to tie any knots and saving surgeons 35-42% of the time required to suture inside the body, according to a recent pre-clinical study. Compared to conventional suturing, the proprietary Endo Stitch™ suturing device can save 45-70% of laparoscopic suturing time, clinical studies show."Covidien works closely with surgeons to develop devices that not only improve patient outcomes, but also make surgery easier, safer and more efficient. We believe that our new V-Loc knotless suturing reloads for minimally invasive surgery will help surgeons perform aspects of their procedures with greater efficiency," said Paul Hermes, Vice President, Chief Technology Officer, Covidien Surgical Solutions. "Covidien is committed to the advancement of bariatric surgery technology and offers a full portfolio of products and services to support bariatric surgeons, their practices and patients."Covidien's comprehensive bariatric surgery portfolio is on display here at the 29th Annual Meeting of the American Society for Metabolic & Bariatric Surgery (ASMBS), which runs through June 22.
