Major retailers recall celery products because of possible E, coli concerns Costco, Target and Starbucks are some of the many retailers pulling products of the shelves because they may be contaminated with E. coli O157:H7. Taylor Farms Pacific of Tracy, CA, is recalling certain products which may include celery which could potentially contain the pathogen.
Scientists draw evidence-based blueprint for HIV treatment, prevention For many years, clinicians debated the best time to start antiretroviral therapy for HIV infection, with some worrying that the risks of treatment in terms of drug toxicities could outweigh the benefits of controlling the virus. Scientists argue that the results of three large clinical trials definitively prove that the benefits of starting ART early in infection outweigh any theoretical risk
Gaming technology may improve X-ray precision With the aim of producing high-quality X-rays with minimal radiation exposure, particularly in children, researchers have developed a new approach to imaging patients based on the Xbox gaming system.

Health Research: Type 2 diabetes reversed by losing fat from pancreas ♦ Enhanced treatment for hepatitis C could cut prevalence by 80 percent

Type 2 diabetes reversed by losing fat from pancreas Type 2 diabetes is caused by fat accumulating in the pancreas, researchers show. They add that losing less than one gram of that fat through weight loss reverses the diabetes.
Enhanced treatment for hepatitis C could cut prevalence by 80 percent Novel antiviral therapies for hepatitis C could reduce the prevalence of the blood-borne infection by more than 80 percent, according to a new analysis. The finding raises the possibility of greatly reducing, and even eliminating, hepatitis C in the United States if enhanced screening and treatment efforts target high-risk populations.

CDC wants to increase awareness of a daily pill that can prevent HIV infection


Approximately 1 in 4 gay, bisexual men; 1 in 5 people who inject drugs; and 1 in 200 heterosexuals should be counseled about pre-exposure prophylaxis (PrEP)
Not enough health care providers know about PrEP.
Not enough health care providers know about PrEP.
A new report published today estimates that 25 percent of sexually active gay and bisexual adult men, nearly 20 percent of adults who inject drugs, and less than 1 percent of heterosexually active adults are at substantial risk for HIV infection and should be counseled about PrEP, a daily pill for HIV prevention.
PrEP for HIV prevention was approved by the Food and Drug Administration in 2012. When taken daily, it can reduce the risk of sexually acquired HIV by more than 90 percent. Daily PrEP can also reduce the risk of HIV infection among people who inject drugs by more than 70 percent. However, according to recent studies, some primary health care providers have never heard of PrEP. Increasing awareness of PrEP and counseling for those at substantial risk for HIV infection is critical to realizing the full prevention potential of PrEP.
“PrEP isn’t reaching many people who could benefit from it, and many providers remain unaware of its promise,” said CDC Director Tom Frieden, M.D., M.P.H. “With about 40,000 HIV infections newly diagnosed each year in the U.S., we need to use all available prevention strategies.”
PrEP is one essential component in the nation’s high-impact prevention strategy
While PrEP can fill a critical gap in America’s prevention efforts, all available HIV prevention strategies must be used to have the greatest impact on the epidemic. These include treatment to suppress the virus among people living with HIV; correct and consistent use of condoms; reducing risk behaviors; and ensuring people who inject drugs have access to sterile injection equipment from a reliable source.
“PrEP has the potential to dramatically reduce new HIV infections in the nation,” says Jonathan Mermin, M.D., M.P.H, director of CDC’s National Center for HIV/AIDS, Viral Hepatitis, STD, and TB Prevention. “However, PrEP only works if patients know about it, have access to it, and take it as prescribed.”

Health News: Doc allegedly made hyperbaric chamber out of used propane tank.♦ Seven minutes of meditation can reduce racial prejudice, ♦ Key molecular players in obesity-associated type 2 diabetes identified

Doc allegedly made  hyperbaric chamber out of used propane tank. Officials announced that a former doctor was charged for allegedly conspiring to defraud the U.S. Food and Drug Administration and commit healthcare fraud when he reportedly created a device from pieces of used propane tanks welded together, and tried to pass it off as a hyperbaric chamber marketed as Hyperbox 101. Authorities also allege that the former doctor received millions of dollars through fraudulent claims submitted to Medicare and other programs.
European hospitals overlook every other person with HIV Many European hospitals fail to routinely test people who may be at risk of an HIV-infection. If tests were more widely used in healthcare, fewer HIV-patients would go unnoticed, especially in Northern Europe.

Drug used to treat HIV linked to lower bone mass in newborns

NIH study finds mothers’ use of tenofovir tied to lower bone mineral content in babies
Infants exposed in the womb to a drug used to treat HIV and reduce the transmission of HIV from mother to child, may have lower bone mineral content than those exposed to other anti-HIV drugs, according to a National Institutes of Health study.
Researchers found that pregnant women who received the drug tenofovir disoproxil fumarate in their third trimester gave birth to babies whose bone mineral content was 12 percent lower than that of infants who were not exposed to the drug in the uterus. Proper mineral content helps strengthen normal bones. The Study appears in Clinical Infectious Diseases.
“At this point, we can say that those who care for pregnant women with HIV and their children should be aware that prescribing tenofovir to pregnant women could be a concern for their infants’ bones,” said George K. Siberry, M.D., the first author of the study and medical officer with NIH’s Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD).
Although the study authors described the results as concerning, they cautioned against any changes in the use of tenofovir in pregnant women. The drug has proved successful as part of drug regimens that treat HIV in pregnant women, and often is used to prevent HIV transmission to infants. The researchers called for additional studies to understand bone health and development among children born to women who took tenofovir during their pregnancies.
“Families should keep in close touch with their physicians to monitor their child’s bone development,” Dr. Siberry added.
In the study, researchers enrolled a total of 143 infants at 14 sites across the United States from 2011 to 2013. Of these participants, 74 were exposed to tenofovir in the uterus, while 69 were given other anti-HIV drugs. Researchers used special, low-radiation X-ray scans, called DXA scans to measure bone mineral content within the first four weeks of birth.
The researchers then compared the bone mineral content of the two groups and found that the group of infants whose mothers took tenofovir, on average, had lower bone mineral content than the group of infants whose mothers were given other kinds of anti-HIV drugs. However, the researchers do not know whether the lower bone mineral content of the children in the tenofovir group is abnormal and will increase the risk of fractures. Dr. Siberry added that it is also unknown whether children can regain bone mineral content as they get older.
The study authors point out that tenofovir use has been associated with bone loss in adults and older children. A few NIH-funded studies have found that adults who used tenofovir were at increased risk for bone fracture.
Information on how to promote healthy bone development in children is available from NIH’s National Institute of Arthritis and Musculoskeletal and Skin Diseases at http://www.niams.nih.gov/health_info/bone/bone_health/juvenile/default.asp#3.

New model to study HIV latency in brain cells Over 35 million people worldwide are currently infected by HIV. Antiviral therapies can keep the virus from multiplying. However, no drug can cure infection so far, because various cell types continue to carry the virus in a latent, i.e. quiescent, state. Scientists have now established a model for latent HIV infection of brain cells. The researchers used this model to identify various compounds that affect latency of the virus in the brain.

HIV Outbreak in Indiana Community


On January 23, 2015, the Indiana State Department of Health (ISDH) began an ongoing investigation of an outbreak of human immunodeficiency virus (HIV) infection, after Indiana disease intervention specialists reported 11 confirmed HIV cases traced to a rural county in southeastern Indiana. Historically, fewer than five cases of HIV infection have been reported annually in this county. The majority of cases were in residents of the same community and were linked to syringe-sharing partners injecting the prescription opioid oxymorphone (a powerful oral semi-synthetic opioid analgesic). As of April 21, ISDH had diagnosed HIV infection in 135 persons (129 with confirmed HIV infection and six with preliminarily positive results from rapid HIV testing that were pending confirmatory testing) in a community of 4,200 persons.
The age range of the 135 patients is 18–57 years , 74 (54.8%) are male. A small number of pregnant women were diagnosed with HIV infection and started on antiretroviral therapy during pregnancy. As of April 21, no infants had tested positive for HIV. Of the 135 persons with diagnosed HIV infection, 108 (80.0%) have reported injection drug use (IDU), four (3.0%) have reported no IDU, and 23 (17.0%) have not been interviewed to determine IDU status. Among the 108 who have reported IDU, all reported dissolving and injecting tablets of oxymorphone as their drug of choice. Some reported injecting other drugs, including methamphetamine and heroin. Ten (7.4%) female patients have been identified as commercial sex workers. Coinfection with hepatitis C virus has been diagnosed in 114 (84.4%) patients.
The patients were interviewed about syringe-sharing and sex partners, as well as any social contacts who also might have engaged in high risk behaviors. Those interviewed reported an average of nine syringe-sharing partners, sex partners, or other social contacts who might be at risk for HIV infection. Of the 373 contacts named as of April 21, a total of 247 (66.2%) had been located, 230 (61.7%) were tested, and 17 (4.6%) either declined testing or were not able to be tested. Of the 230 contacts who were tested, test results for 109 (47.4%) were HIV positive, and 121 (52.6%) were HIV negative. Of the 128 contacts who have not yet been located, 74 (57.8%) have been identified as syringe-sharing or sex partners, and 54 (42.2%) are social contacts regarded as at high risk for HIV infection.
Injection drug use in this community is a multi-generational activity, with as many as three generations of a family and multiple community members injecting together. IDU practices include crushing and cooking extended-release oxymorphone, most frequently 40 mg tablets not designed to resist crushing or dissolving. Syringes and drug preparation equipment are frequently shared (e.g., the drug is dissolved in nonsterile water and drawn up into an insulin syringe that is usually shared with others). The reported daily numbers of injections ranged from four to 15, with the reported number of injection partners ranging from one to six per injection event.
Like many other rural counties in the United States, the county has substantial unemployment (8.9%), a high proportion of adults who have not completed high school (21.3%), a substantial proportion of the population living in poverty (19%), and limited access to health care (1). This county consistently ranks among the lowest in the state for health indicators and life expectancy (2).
ISDH worked with the only health care provider in the immediate community, local health officials, law enforcement, community partners, regional health care providers and CDC to launch a comprehensive response to this outbreak. A public health emergency was declared on March 26 by executive order (3). The response has included a public education campaign, establishment of an incident command center and a community outreach center, short-term authorization of syringe exchange, and support for comprehensive medical care including HIV and hepatitis C virus care and treatment as well as substance abuse counseling and treatment. State and local health departments and academic partners, with the assistance of CDC, are working to implement and improve the community outreach programs supported by the executive order and to interrupt IDU-related HIV and hepatitis C virus transmission. Contact tracing by state and CDC disease intervention specialists continues to identify those potentially exposed.
This HIV outbreak involves a rural population, historically at low risk for HIV, in which HIV infection spread rapidly within a large network of persons who injected prescription opioids. The Indiana public health response includes implementing programs to contain the spread of HIV and hepatitis C virus, curb injection drug use, and concurrently build social resilience in the community. The outbreak highlights the vulnerability of many rural, resource-poor populations to drug use, misuse, and addiction, in the context of a high prevalence of unaddressed comorbid conditions (4). The outbreak also demonstrates the importance of timely HIV and Hepatitis C surveillance activities and rapid response to interrupt disease transmission. Finally, the outbreak points to the need for expanded mental health and substance use treatment programs in medically underserved rural areas (5).

HIV Immunotherapy Promising in First Human Study

HIV, the virus that causes AIDS, attacks and destroys immune cells. Current treatment with antiretroviral therapy helps to prevent the virus from multiplying. But despite advances in treatment, scientists haven’t yet designed a vaccine that protects people from HIV.

Researchers have discovered many human antibodies that can neutralize multiple strains of HIV. They’ve gained important insights into how these broadly neutralizing antibodies bind to the virus and why they're effective. However, it’s been a challenge to design a vaccine that prompts the human immune system to generate such antibodies and mount an effective attack against the virus.
A team led by Dr. Michel C. Nussenzweig of the Howard Hughes Medical Institute at Rockefeller University has been exploring a different approach. In previous work, they isolated broadly neutralizing antibodies from people and produced them in the lab. These so-called monoclonal antibodies could prevent or treat infection with HIV or its monkey equivalent in mice and macaques.
In the current study, the researchers evaluated one of these promising monoclonal anti-HIV antibodies in people. The small phase 1 clinical trial included 29 volunteers—17 HIV-infected and 12 uninfected
The participants received a single intravenous dose (of 1, 3, 10, or 30 milligrams per kilogram of body weight) of the experimental antibody called 3BNC117. The antibody was well-tolerated by all participants. Among those infected with HIV, the 2 lower doses caused small and transient changes in blood HIV levels. The 8 participants who received the highest dose, however, had significant and rapid decreases in HIV. The virus’s resistance to the antibody was variable. In some people, HIV remained sensitive to 3BNC117 for 28 days.
“What’s special about these antibodies is that they have activity against over 80% of HIV strains and they are extremely potent,” says study coauthor Dr. Marina Caskey.
“In contrast to conventional antiretroviral therapy, antibody-mediated therapy can also engage the patient’s immune cells, which can help to better neutralize the virus,” adds co author Dr. Florian Klein.
This study suggests that 3BNC117 is safe in people and could help to control HIV. Future studies will continue to explore the use of this and other broadly neutralizing antibodies in HIV prevention and treatment.
