• New test for infectious disease promises quick diagnosis

    Researchers have come up with a way for inventing molecule probes quickly to identify deadly bacterial strains of infectious disease. The test can be done in less than an hour, compared to the current forty-eight hours, allowing for rapid, more accurate treatment of patients.

  • Suicide bomber kills 15 outside polio clinic in Quetta, Pakistan

    The Taliban’s violent campaign against bringing Western medicine to children in Pakistan, a campaign which focused primarily on disrupting the efforts of the Pakistani government and international NGOs to fight polio, continues. Earlier today (Wednesday), a suicide bomber has killed at least fifteen people, most of them police, outside a polio eradication center in the city of Quetta in western Pakistan.

  • Cheat-proof smartphone knows when you are faking activity

    Health care providers and insurance companies are increasingly relying on smartphone and wearable activity trackers to reward active individuals for healthy behavior or to monitor patients. But because activity trackers can be easily deceived, researchers have designed a way to train smartphone trackers to spot the difference between fake and real activity.

  • Sharing of research data, findings should be the norm in public health emergencies

    Opting in to data sharing should be the default practice during public health emergencies, such as the recent Ebola epidemic, and barriers to sharing data and findings should be removed to ensure those responding to the emergency have the best available evidence at hand, experts say.

  • Toxins found in fracking fluids and wastewater: Study

    In an analysis of more than 1,000 chemicals in fluids used in and created by hydraulic fracturing (fracking), researchers found that many of the substances have been linked to reproductive and developmental health problems, and the majority had undetermined toxicity due to insufficient information. The researchers say that further exposure and epidemiological studies are urgently needed to evaluate potential threats to human health from chemicals found in fracking fluids and wastewater created by fracking.

  • Gov. Brown declares emergency in wake of massive L.A. natural gas leak

    California governor Jerry Brown on Wednesday declared an emergency in a Los Angeles neighborhood where a natural gas well has been spewing record amounts of stinking, global-warming methane gas. Energy experts said the breach at the natural gas storage reservoir, and the subsequent, ongoing release, are the largest known occurrence of its kind.

  • Identifying areas of plague risk in Western U.S.

    Plague was first introduced into the United States in 1900, by rat–infested steamships which had sailed from affected areas. Epidemics occurred in port cities, with the last urban plague epidemic in the United States occurring in Los Angeles from 1924 through 1925. Researchers have identified and mapped areas of high probability of plague bacteria in the western United States. The findings may be used by public health agencies to aid in plague surveillance.

  • Study links insurgency phase of Iraq War to higher PTSD rates

    Guerilla tactics such as suicide attacks and roadside bombs may trigger more posttraumatic stress than conventional warfare, suggests a Veterans Affairs study of 738 men and women who served in Iraq. The study found that among the men — about half the overall group — the insurgency-phase veterans were more than twice as likely to have a diagnosis of PTSD, compared with those who served in either of the other two phases.

  • Making mobile health more secure

    With Internet-connected medical technology and digitized health records on the rise, cybersecurity is a growing concern for patients and hospitals alike. For example, a patient’s insulin pump may accept dosage instructions from unauthorized smartphones that have been infected with malicious software, or a patient’s fertility-tracking app could expose itself to nearby strangers by probing for a Bluetooth device to connect with. One research team is taking a holistic approach to strengthening the medical system’s security — from the computer networks that support hospitals, to the cloud, to the smart phone in your pocket.

  • Studying gun violence is the only way to figure out how to stop it – but we don’t

    There are about 32,000 gun deaths a year in the United States. There are another 180,000 or so people injured by firearms annually in the country. These numbers far outstrip the consequences of firearms among our peer high-income countries, with stricter gun regulations. One factor that has inhibited the discussions in the public space over gun violence is the relatively limited data we have available about firearms and firearm violence. Gun violence is a public health problem, but it is not studied the same way other public health problems are. The reason: In 1996 the NRA pushed Congress to prohibit the use of funds made available for injury prevention and control at the Centers for Disease Control and Prevention to be used to advocate or promote gun control. The CDC broadly interpreted this as a bar on firearms research, with other federal funders following suit. This has had a chilling effect on gun research. Because of the bar on research, our understanding of the real consequences of the firearm epidemic is surface deep. The United States has had enormous success in responding to other challenges to public health, including, for example, motor vehicle safety, through gathering data that understands the challenge and implementing structural changes to mitigate the potential harm. On the issue of firearm violence, we are not even at the first step.

  • FDA clears military traumatic wound dressing for use in civilian population

    Early control of severe bleeding may prevent shock and may be life-saving., as 30 to 40 percent of civilian deaths by traumatic injury are the result of hemorrhaging. Of those deaths, 33 to 56 percent occur before the patient reaches a hospital. Last week the FDA cleared the use of the XSTAT 30 wound dressing, an expandable, multi-sponge dressing used to control severe, life-threatening bleeding from wounds in areas that a tourniquet cannot be placed (such as the groin or armpit) in battlefield and civilian trauma settings.

  • Flu season likely to peak in February

    According to the CDC, seasonal influenza affects up to 20 percent of people in the United States and causes major economic impacts resulting from hospitalization and absenteeism. The flu season will likely peak in February in most parts of the United States, according to a model developed by scientists at Los Alamos National Laboratory. Using historical data, a mathematical representation of how flu spreads through a population, and data for the current flu season provided by the Centers for Disease Control and Prevention (CDC), the scientists were able to create a probabilistic model forecasting the flu season.

  • Scientists develop new way to find age of drinking water

    It can take days for water to travel from a filtration plant to your tap and the length of time the journey takes could affect water quality. Disinfectants from water treatment, like chlorine, prevent the growth of harmful microbes, but they can break down over time, creating toxic byproducts in the process. Minimizing the water’s travel time in pipes reduces both processes, but measuring that time is difficult. Scientists have developed a new method of finding the age of water at any point in a distribution system using something that is already naturally in water: residual radioactive atoms from nuclear fallout of the 1950s and early 1960s.

  • WH finalizing executive order tightening background checks of gun buyers

    Sources say that the White House is about to announce a new executive order to expand background checks of individuals wishing to purchase guns. One proposal being considered would designate more sellers as high-volume dealers, closing a legal loophole which allows many sales conducted online or at gun shows to escape existing background check provisions. Two other developments on the gun front: On Thursday, Connecticut governor Dan Malloy said he would sign an executive order which would bar people on the government’s terrorism watch lists from buying guns in Connecticut; in the House, Democrats demand that a 17-year ban on government-funded research into violence involving firearms be ended.

  • U.S. capability for treating Ebola outbreak sufficient but limited

    The United States has sufficient capacity for treating another outbreak of the Ebola virus, but financial, staffing and resource challenges remain a hurdle for many hospitals and health systems attempting to maintain dedicated treatment centers for highly infectious diseases, according to new study.
