 Large Hadron Collider, finally began to collide subatomic particles.
PASADENA, Calif. — After 16 years and $10 billion — and a long morning of electrical groaning and sweating — there was joy in the meadows and tunnels of the Swiss-French countryside Tuesday: the world’s biggest physics machine, the Large Hadron Collider, finally began to collide subatomic particles./.../

Dr. Michael de Ridder says that, “today about one in 20 patients survives resuscitation. Take away those who leave the hospitals requiring long-term intensive care
and the success rate drops.”
Michael de Ridder, the head of the emergency ward at a Berlin hospital discusses how modern medical advances are making death more complicated for patients with little hope of living. He makes a plea for doctors to allow people to die with greater dignity.

Physicians' Plea: Ban the Bomb!

A new international campaign against nuclear war
"How can we dispel the notion of some people that anyone will survive a nuclear war? How can we as doctors influence people to prevent any further buildup of nuclear arms?" These are not the questions of an American pacifist but of Dr. Yevgeni Chazov, the Soviet Union's deputy minister of health and an official physician to President Leonid Brezhnev. Moreover, Chazov's view is at variance with some statements by Soviet officials implying that since fewer Soviet citizens are likely to die in an atomic holocaust than Americans, the U.S.S.R. would therefore win.
The idea that either superpower could emerge victorious from a nuclear war is also gaining currency among some U.S. strategists. Vice President-elect George Bush told the Los Angeles Times a year ago that he believed there was such a thing as "a winner in a nuclear exchange." He was echoing the views of some U.S. strategists, including the Hudson Institute's Colin Gray and Keith Payne, who have argued that "the U.S. must possess the ability to wage nuclear war rationally." Alarmed by such statements, some American and Soviet physicians have decided to begin a campaign to dispel what they consider to be a dangerous myth of survivability that may increase the possibility of a nuclear war.
According to U.S. experts, a 20-megaton nuclear warhead, 1,000 times as powerful as the atomic bomb dropped on Hiroshima, detonated over Boston would destroy everything within a four-mile radius. Up to ten miles away from ground zero, fire storms would devastate all buildings and trees. Of the 3 million inhabitants of metropolitan Boston, 2.2 million would be killed outright. Almost every survivor would be maimed, burned or in shock. Of the 6,000 physicians in the area, only 900 would be fit enough to treat the injured. In time, survivors would develop new and virtually incurable ailments, such as severe radiation poisoning and reactions to contaminated food and water.
The recital of this scenario by Dr. Howard Hiatt, dean of Harvard's School of Public Health, stunned a conference in Cambridge, Mass. Declared Hiatt: "Inadequate means of dealing with an epidemic permits only one approach—that of prevention."
To that end, a group of U.S. physicians, headed by Harvard Cardiologists Bernard Lown and James Muller, has organized International Physicians for the Prevention of Nuclear War, Inc. They have recruited several eminent Americans, including Jonas Salk and Nobel Laureate Hamilton Smith. They also got a strong endorsement from Chazov, who wrote: "The medical profession should more actively protest against the senseless policy of increasing arsenals of thermonuclear arms."
At the organization's first conference, scheduled for late March at Airlie House near Washington, some 60 participants from Japan, France, Britain, the U.S. and the Soviet Union will discuss the medical history of Hiroshima and Nagasaki and attempt to determine what the effects of a future thermonuclear war might be. They also hope to present their findings to congressional committees and Reagan Administration officials.
Both Soviet and American physicians are keenly aware of the danger of being used for propaganda purposes by their own, as well as each other's politicians. Says Chazov: "I think our movement would lose a lot of credibility if it became political." ∎

EMP: The Next Weapon of Mass Destruction?

This article recalls me the 1980's Professor Bernard Lown alert

By Mark Thompson / Washington Tuesday, Mar. 30, 2010
If America needs a new threat around which to organize its defenses, try this one: Bad guys explode nuclear weapons miles above U.S. soil, sending out an electromagnetic pulse (EMP) that fries the electronic guts of everything in America. The nation's financial and transportation systems collapse, hospitals and the Internet go dark, water and electrical grids freeze and runaway Toyotas with electronic throttles are finally brought to a stop. "The EMP resulting from the blast would cause widespread damage, devastating the economy and resulting in the deaths of millions of Americans," the hawkish Heritage Foundation warned last week, launching a call on Congress to establish an EMP Recognition Day./.../

Dependência química é doença do cérebro


Dependência química é doença do cérebro, diz diretora do Nida
Nora Volkow, chefe do Instituto Nacional sobre Abuso de Drogas dos Estados Unidos, ministrou palestra na Unifesp. Evento reuniu cerca de 400 pessoas

Danilo Maeda | Assessora Comunicação
Cerca de 400 pessoas assistiram a palestra
Na tarde de ontem, o auditório da Universidade Federal de São Paulo (Unifesp) recebeu uma das maiores especialistas em drogas da atualidade: a psiquiatra Nora Volkow, diretora do Instituto Nacional sobre Abusos de Drogas dos Estados Unidos (Nida, na sigla em inglês).

Durante a palestra, a especialista afirmou que a dependência química é uma doença crônica que compromete diretamente as funções do cérebro. De acordo com ela, o uso contínuo de substâncias psicoativas atinge uma região do cérebro chamada córtex orbitofrontal, que é responsável pela tomada de decisões. “Essa área também é afetada no transtorno obsessivo-compulsivo. É a região do cérebro que nos permite mudar o comportamento de acordo com a necessidade. Por isso, algumas pessoas dizem que não sentem mais prazer com o uso da droga, mas mesmo assim não conseguem parar. Elas perdem o livre arbítrio para dizer ‘não’”, destacou.

Working Class in England, 1845

"When one individual inflicts bodily injury upon another such injury that death results, we call the deed manslaughter; when the assailant knew in advance that the injury would be fatal, we call his deed murder. But when society places hundreds of proletarians in such a position that they inevitably meet a too early and an unnatural death, one which is quite as much a death by violence as that by the sword or bullet; when it deprives  thousands of the necessaries of life, places them under conditions in  which they cannot live -- forces them, through the strong arm of the law,  to remain in such conditions until that death ensues which is the  inevitable consequence -- knows that these thousands of victims must  perish, and yet permits these conditions to remain, its deed is murder just as surely as the deed of the single individual; disguised, malicious murder, murder against which none can defend himself, which does not seem what it is, because no man sees the murderer, because the death of the victim seems a natural one, since the offence is more one of omission than of commission. But murder it remains."

Implicit Value Judgments in the Measurement of Health Inequalities

Volume 88, Number 1, 2010

Sam Harper, Nicholas B. King, Stephen C. Meersman, Marsha E. Reichman, Nancy Breen, and John Lynch McGill University; Case Western Reserve University; National Cancer Institute; University of South Australia; University of Bristol 

Context: Quantitative estimates of the magnitude, direction, and rate of change of health inequalities play a crucial role in creating and assessing policies aimed at eliminating the disproportionate burden of disease in disadvantaged populations. It is generally assumed that the measurement of health inequalities is a value-neutral process, providing objective data that are then interpreted using normative judgments about whether a particular distribution of health is just, fair, or socially acceptable.
Methods: We discuss five examples in which normative judgments play a role in the measurement process itself, through either the selection of one measurement strategy to the exclusion of others or the selection of the type, significance, or weight assigned to the variables being measured.
Findings: Overall, we find that many commonly used measures of inequality are value laden and that the normative judgments implicit in these measures have important consequences for interpreting and responding to health inequalities.
Conclusions: Because values implicit in the generation of health inequality measures may lead to radically different interpretations of the same underlying data, we urge researchers to explicitly consider and transparently discuss the normative judgments underlying their measures. We also urge policymakers and other consumers of health inequalities data to pay close attention to the measures on which they base their assessments of current and future health policies.
Keywords: Health inequalities, measurement, ethics, health policy.

The WHO Tobacco Free Initiative announces the third volume of the WHO Study Group on Tobacco Product Regulation (TobReg) Technical Report Series on the Scientific Basis of Tobacco Product Regulation. This WHO Technical Report Series makes available the findings of an international group of experts that provide WHO with the latest scientific and technical advice in the area of product regulation.
The third report presents the conclusions reached and recommendations made by the members of the WHO Study Group on Tobacco Product Regulation at its fifth meeting, during which it reviewed two background papers specially commissioned for the meeting and which dealt, respectively, with the following two themes.
  • Devices designed for the purpose of nicotine delivery to the respiratory system in which tobacco is not necessary for their operation.
  • Setting regulatory limits for carcinogens in smokeless tobacco.
The Study Group's recommendations in relation to each theme are set out at the end of the section dealing with that theme. Its overall recommendations are summarized in section 4.
The Study Group intends this new set of recommendations to be useful to WHO Member States and national policymakers and regulators in shaping tobacco control policy. The English will be available shortly in print format, and the other UN-language versions will be available soon.

Promoting Cardiovascular Health in the Developing World

Promoting Cardiovascular Health in the Developing World: A Critical Challenge to Achieve Global Health

Preventing the Global Epidemic of Cardiovascular Disease: Meeting the Challenges in Developing Countries
Board on Global Health
Cardiovascular disease (CVD), once thought to be confined primarily to industrialized nations, has emerged as a major health threat in developing countries. Cardiovascular disease now accounts for nearly 30 percent of deaths in low and middle income countries each year, and is accompanied by significant economic repercussions. Yet most governments, global health institutions, and development agencies have largely overlooked CVD as they have invested in health in developing countries. Recognizing the gap between the compelling evidence of the global CVD burden and the investment needed to prevent and control CVD, the National Heart, Lung, and Blood Institute (NHLBI) turned to the IOM for advice on how to catalyze change.
In this report, the IOM recommends that the NHLBI, development agencies, nongovernmental organizations, and governments work toward two essential goals:
  • creating environments that promote heart healthy lifestyle choices and help reduce the risk of chronic diseases, and
  • building public health infrastructure and health systems with the capacity to implement programs that will effectively detect and reduce risk and manage CVD./.../

O universo é um computador quântico

Luciana Galastri em 22.03.2010 as 23:23
Do que o universo é feito? Matéria? Matéria escura? Energia? Vibrações? De acordo com um físico chamado Vlatko Vedral, nosso universo é feito de informação.
Parece até conversa de palestrantes que ganham a vida ensinando pessoas a se expressarem bem – mas a teoria de Vlatko é bem diferente. Segundo o físico, se quebrarmos o universo em pedaços cada vez menores o que sobraria no final são bits.
Sim, esses bits de informação que você carrega em seu computador mesmo. Um bit é o menor pedaço de informação – ele representa a distinção entre duas possibilidades (sim ou não, verdadeiro ou falso, zero ou um, e por aí vai). A palavra bit, em inglês, se refere à unidade física de armazenamento de informação de seu computador – um bit é registrado por um imã minúsculo em um dos pólos de seu drive de memória.

Omega-3 Fatty Acid Protects Against Polyps

Omega-3 Fatty Acid Protects Against Polyps

Action Points  
  • Explain to interested patients that a new formulation of the fatty acid found in fish oil showed promise in the prevention of colorectal cancer in patients with familial adenomatous polyposis, according to a randomized study.
  • Explain that although the study was performed in patients with a genetic predisposition to colorectal cancer, the benefits also might extend to noninherited, or sporadic, colon cancer. But this has not yet been studied.
An omega-3 polyunsaturated fatty acid significantly reduced both the number and size of rectal polyps in patients with familial adenomatous polyposis, a randomized trial found.
Six months of treatment with the free fatty acid formulation of eicosapentaenoic acid (EPA) led to a decrease in mean number of polyps from 4.13 at baseline to 3.61, a 12.4% decrease, according to Nicholas J. West, MBBS, of St. Mark's Hospital in London, and colleagues.
In contrast, six months of placebo treatment resulted in an increase from 4.50 polyps at baseline to 5.05, which represented a 9.7% increase, the researchers reported online in Gut.
