‘Intelligent knife’ tells surgeon which tissue is cancerous

In the first study to test the invention in the operating theatre, the "iKnife" diagnosed tissue samples from 91 patients with 100 per cent accuracy, instantly providing information that normally takes up to half an hour to reveal using laboratory tests. The findings, by researchers at Imperial College London, are published today in the journal Science Translational Medicine. The study was funded by the National Institute for Health Research (NIHR) Imperial Biomedical Research Centre, the European Research Council and the Hungarian National Office for Research and Technology. …

Large UK population study finds no increased cancer risk in children born after assisted conception

Results of the study were presented today at the annual meeting of ESHRE by Dr Carrie Williams from the Institute of Child Health, University College London, UK. This was a large population-based linkage study between the Human Fertilisation & Embryology Authority (HFEA, the UK’s regulatory authority for ART clinics) and the UK’s National Registry of Childhood Tumours (NRCT).(1) The HFEA records of all 106,381 children born after assisted conception in the UK from 1992 to 2008 were linked to NRCT records to calculate the number of children who subsequently developed cancer. Once the databases were linked, cancer rates in the ART cohort were compared with population rates, whilst stratifying for potential mediating factors including birth weight, multiple births, treatment type and infertility cause. …

Cells play ‘tag’ to determine direction of movement

Scientists from Barcelona and London, looked at cells in the neural crest, a very mobile embryonic structure in vertebrates that gives rise to most of the peripheral nervous system and to other cell types in the cardiovascular system, pigment cells in the skin, and some bones, cartilage, and connective tissue in the head. Researchers saw that, during development, these neural crest cells ‘chase’ other types of cells — so-called placodal cells that give rise to the sensory organs — which dash away when approached, thus propelling the cell sheet in a certain direction. "The effect can also be likened to a donkey and carrot effect, with the neural crest cells — the donkey — chasing but never quite reaching the carrot, the placodal cells," explains Xavier Trepat, ICREA Research Professor of the UB and leader of the Research Group on Integrative Cell and Tissue Dynamics of IBEC…

Malnutrition condemns millions to stunted lives, UNICEF claims

Some 165 million children worldwide are stunted by malnutrition as babies and face a future of ill health, poor education, low earnings and poverty, the head of the United Nations children's fund said on Friday. Anthony Lake, executive director of UNICEF, told Reuters the problem of malnutrition is vastly under-appreciated, largely because poor nutrition is often mistaken for a lack of food. In reality, he said, malnutrition and its irreversible health consequences also affect relatively well-off countries, such as India where there is plenty of food, but access to it is unequal and nutritional content can be low. “Undernutrition, and especially stunting, is one of the least recognized crises for children in the world,” Lake said. “It's a horrible thing. These children are condemned.” Stunting is the consequence of undernutrition in the first 1,000 or so days of a baby's life, including during gestation. Stunted children learn less in school and are more likely themselves to live in poverty and go on to have children also stunted by poor nutrition. These in turn increase poverty in affected countries and regions, and drive greater gaps between the rich and the poor, Lake said. “The numbers are phenomenal. In India, for example, about 48 percent of children are stunted, and in Yemen it's almost 60 percent. Just think of the drag on development,” Lake said. “And the key point is that it is absolutely irreversible. You can feed up an underweight child, but with a stunted child, because of the effects on the brain, it has a permanently reduced cognitive capacity by the age of around two years old.” “Nutrition for growth” Lake spoke to Reuters in London ahead of a “Nutrition for Growth” summit on Saturday co-hosted by the British and Brazilian governments and the Children's Investment Fund Foundation (CIFF), at which donor countries are expected to pledge more funding to tackle the problem. The summit coincides with the publication in The Lancet medical journal of a series of studies on the issue, which found that as well as the 165 million children stunted by poor nutrition, nearly half of all deaths among under fives - 3.1 million deaths a year - are caused by malnutrition. UNICEF says it wants to focus global efforts for now on 20 countries - mostly in Africa and Asia - which are home to 70 percent of the world's stunted children. The cost of tackling poor nutrition in these countries is estimated to be about $7 billion a year, Lake said. Saturday's summit aims to secure pledges for about half that amount. Securing those funds and using them effectively to improve nutrition would be “extraordinarily cost-effective”, Lake said, since the negative effects of malnutrition and stunting currently cost an estimated 11 percent of gross domestic product (GDP) economic output in Africa and Asia. Achieving food security - ensuring countries have enough food to go around - however, should not be mistaken for addressing the problem of poor nutrition, he said. “The fact is that India, with 48 percent (childhood) stunting, is considered food secure - but that doesn't mean food is distributed equitably within India. “And in Africa, for instance, if you only eat cassava, then your belly may be full and you may technically have food security, but that doesn't mean you're getting the nutrition needed to prevent stunting.” Lake also stressed that increased funding was only part of the solution and that spending donor funds wisely in trusted community-based programs is essential. Such programs need to cover a range of measures, including promoting more nutritious foods, recommending exclusive breastfeeding for the first six months of a baby's life and using micronutrient supplements to boost vitamin A, folic acid, zinc and iron.source : http://www.foxnews.com/health/2013/06/07/malnutrition-condemns-millions-to-stunted-lives-unicef-claims/

Group therapy helps rape victims in poor countries

Group therapy works better than individual support for women in low-income countries who have been victims of sexual violence, according to the results of a new study done in the Democratic Republic of Congo (DRC). The method has already been shown to be effective in wealthier countries. Because measures of depression, anxiety, general functioning and post-traumatic stress disorder improved faster with group therapy, the technique may be useful in other countries were war and unrest often contribute to sexual violence, researchers reported in the New England Journal of Medicine. “We're giving them the skills to rethink the meaning they're giving to their thoughts and feelings” about their attack, lead author Judith Bass of the Johns Hopkins Bloomberg School of Public Health in Baltimore told Reuters Health. The study “offers promising evidence” that a form of group therapy can help women who have been exposed to sexual violence, Charlotte Watts and her colleagues at the London School of Hygiene and Tropical Medicine wrote in a linked editorial. In the DRC, 40 percent of women have been victims of some type of sexual violence. The researchers evaluated 157 women in seven villages who were offered one individual session and 11 group sessions of so-called cognitive processing therapy. “The women were being taught to identify what thoughts are not helpful to them,” Bass explained. “Thinking 'It's my fault' is not helpful to them. And it involves how to deal with that and get over some of these thoughts that are keeping them from healing.” Those women were compared with 248 women in eight villages who received individual support that included counseling and sympathetic listening. Women in both treatment groups improved even though each village had at least one major security incident during the trial, including attacks and armed robberies. But the improvement was most pronounced with group cognitive therapy. On a combined scale of depression and anxiety, where the worst score was 3 and the best was 0, women in the cognitive therapy group went from 2.0 at the outset to 0.8 at the end of treatment. Six months after treatment their average score was 0.7. The respective scores for women receiving individual support started at 2.2, dropped to 1.7 and eventually fell to 1.5. After six months, 9 percent of group therapy participants and 42 percent of women who received individual support still likely had a diagnosis of depression or anxiety, Bass and her colleagues found. The study did not include the most severe cases - seven of the 494 women screened for the study were found to be severely suicidal and were treated immediately. “Despite illiteracy and ongoing conflict, this evidence-based treatment can be appropriately implemented and effective,” the researchers concluded. “Given the high rates of sexual violence globally, and especially in conflict-affected countries such as the DRC, this finding is very important,” the Watts team wrote in its editorial. “Rape during war is not unique to the DRC; indeed, it affects many, if not most, countries that are at war, including several African states and, more recently, countries in the Middle East.” The study was funded by the World Bank and the U.S. Agency for International Development Victims of Torture Fund. “We do this because we see mental health as such a large cause of disability and dysfunction,” Bass said. “We want to improve people's health. But when you have such high rates of rape and violence, and such a high rate of mental health problems, it's an often-neglected piece in the bigger development picture.”source : http://www.foxnews.com/health/2013/06/06/group-therapy-helps-rape-victims-in-poor-countries/
