• Information sharing seen as public health "game changer"

    Public health officials are pushing for the creation of shared databases that contain electronic health records (EHRs) to help combat infectious diseases and stop epidemics; a CDC official pointed to the positive impact that electronic health information exchanges (HIE) have on public health; during the 2003 SARS outbreak, Milwaukee helped establish a four-state network that automatically detected new cases of SARS based on electronic reports from local hospital emergency rooms; manual reporting of test results is a slow process, but with the use of electronic reporting public health officials can now quickly identify epidemics and pandemics as they occur

  • Nine die in Alabama from infected IVs

    Alabama public health officials are currently investigating the deaths of nine patients who received intravenous nutrition from contaminated feedbags; officials say that the intravenous nutrition solution, called total parenteral nutrition (TPN), contained Serratia marcescens bacteremia, which leads to a bacterial infection in the blood; investigators have traced the source of the contaminated intravenous nutrition feed bags to the pharmaceutical supplier Meds IV; the bacteria is commonly found and it is difficult to specifically link the organisms that killed the nine patients to those found at Meds IV facility

  • Information about Maryland biolabs scarce

    High-level containment laboratories and storage facilities that handle dangerous biological agents exist in Frederick County, Maryland, outside the secured gates of Fort Detrick, but state law mandates that the number and location of each remains confidential; supporters of the current system say that confidentiality is critical to maintain the security and safety of the labs, but critics argue that the secrecy makes it impossible for emergency services in the neighborhood to prepare properly for accidents

  • Full-body scanners not a health risk

    A new study concludes that there is “no significant threat” from backscatter X-ray scanners; even though they use ionizing radiation, which is known to cause cancer, the doses are so low — less than 1 percent of the additional radiation a person gets from flying in an airplane in the first place, and about the same received through 3 to 9 minutes of daily life on the ground — that only a handful of cancer cases are likely to result directly from scanner use

  • Canada launches TB website to stem spread of disease

    Researchers at Canada’s McGill University recently launched a free website to help doctors around the world stem the spread of tuberculosis (TB); the website offers detailed information on TB vaccinations in over 180 countries; while TB levels are at all-time lows in Canada and the United States, TB has grown increasingly prevalent around the world particularly in Africa and India; in India, there are nearly two million new cases of TB each year and it is the leading cause of death among people between the ages of fifteen and forty-five; the International Federation of Red Cross and Red Crescent Studies recently warned that up to ten million people could die of TB by 2015; if detected early, TB can be treated with antibiotics

  • The health effects of airport security scanners

    The Transportation Security Administration (TSA) has begun to use whole-body imaging scanners as a primary screening measure on travelers passing through airport security checkpoints; one type of scanner employs millimeter wave technology, which delivers no ionizing radiation; the second type of scanner currently deployed at airports, however, uses backscatter X-rays that expose the individual being screened to very low levels of ionizing radiation; what are the health implications of these scanners? Two prominent radiologists offer answers

  • Stemming the spread of disease at airports

    With roughly two million people flying each day and spending hours in confined areas where they will come into close contact with potentially infected people, air travel poses a serious challenge to public health officials seeking to contain major disease outbreaks; last month public health officials scrambled to contain a potential mass outbreak of measles after a woman flew through three U.S airports, coming into contact with thousands of people; a CDC report recommends using infrared thermal scanners to detect passengers with fevers as that is an easily recognizable symptom and it is a common indicator of most infectious diseases

  • Official: U.S. safe from Japanese radiation

    U.S nuclear officials said that there was very little chance that harmful levels of radiation from Japan’s nuclear reactors would reach Hawaii or the west coast of the United States; the head of the Nuclear Regulatory Commission (NRC) also said nuclear plants in the United States were designed to withstand natural disasters like earthquakes and tsunamis; readings from radiation sensors placed on the west coast have not detected any increases in radiation levels and experts do not expect any increases; Japanese utilities have flooded two nuclear reactors with sea water in a desperate attempt to cool them down and prevent a meltdown; the NRC has dispatched two nuclear experts to Japan to assist with efforts to keep three damaged reactors from melting down

  • Future of U.S. nuclear plans uncertain after Japanese nuclear crisis

    As Japan continues its struggle to control its nuclear reactors, the future of the U.S. nuclear industry has become increasingly uncertain; nuclear power had emerged as the bipartisan solution to easing America’s dependency on oil; in February 2010, President Obama announced $8.3 billion in loan guarantees to energy companies to build the first new nuclear power plants in the United States in almost thirty years; some lawmakers have called for a moratorium and stricter safety regulations, while others are urging for a more measured response; Energy Secretary Stephen Chu and Gregory B. Jaczko, the chairman of the Nuclear Regulatory Commission, will testify before the House Energy and Commerce committee on Wednesday

  • Radioactive waste contaminates drinking water, EPA does nothing

    Recent Environmental Protection Agency (EPA) documents show that Pennsylvania’s drinking water has been contaminated with radioactive waste from natural gas drilling; energy companies have been extracting natural gas with a new drilling technique called “hydrofracking”; this process results in millions of gallons of wastewater that is contaminated with dangerous chemicals like highly corrosive salts, carcinogens, and radioactive elements; EPA documents reveal the process has been contaminating drinking water supplies across the country with radioactive waste; in Pennsylvania more than 1.3 billion gallons of radioactive wastewater was trucked to plants that could not process out the toxins before it released the water into drinking supplies

  • Medical isotopes could be made without a nuclear reactor

    Canadian researchers are racing to perfect a safe, clean, inexpensive, and reliable method for making isotopes used in medical-imaging and diagnostic procedures — a method which would not require a nuclear reactor and could, therefore, eliminate future shortages of technetium-99m, the most widely used medical isotope today; what is more, the new method generates virtually no radioactive waste materials that must be stored indefinitely

  • Enzyme provides protection against nerve gas

    Nerve agents disrupt the chemical messages sent between nerve and muscle cells, causing loss of muscle control, and ultimately leading to death by suffocation; protection against nerve gas attack is a significant component of the defense system of many countries around the world; nerve gases are used by armies and terrorist organizations, and constitute a threat to both the military and civilian populations, but existing drug solutions against them have limited efficiency; a multidisciplinary team of scientists at the Weizmann Institute of Science in Israel, succeeded in developing an enzyme that breaks down nerve agents efficiently before damage to nerves and muscles is caused

  • Disgraced doctor had secret businesses to exploit vaccine fears

    Disgraced doctor Andrew Wakefield, who used fraudulent data to “prove” a relationship between vaccination of children and autism — triggering a health crisis in 1998 — has been revealed to have planned to benefit from his fraud: in a prospectus to investors, from whom Wakefield was trying to raise an initial 700,000 Pounds, he predicts the investors could make up to 28 million Pounds($43,367,082; 33,290,350 Euros) a year from the diagnostic kits his company would sell to parents who Wakefield had intentionally scared with his “revalations” about the source of autism

  • U.S. moves to address antibiotic resistant bacterial diseases

    Antibiotic resistant strands of bacteria are on the rise and threatening the efficacy of existing drug treatments; scientists fear a time when antibiotics will be useless to stop infections due mutations caused by the overuse of antibiotics; legislation has been introduced at the federal and state level targeting the overuse of antibiotics in farm animals to help reduce the prevalence of super bacteria; an FDA study found that 80 percent of all antibiotics produced in the U.S. went to farm animals

  • Food packaging indicates food freshness

    An estimated 8.3 million tons of household food — most of which could have been eaten — is wasted in the United Kingdom each year because retailers and consumers question whether the food is safe to eat; researchers at Glasgow’s Strathclyde University are developing a plastic indicator that alerts consumers to food that is starting to go off; the new indicator will change color to provide a warning when food is about to lose its freshness
