A male adult film star in California who underwent regular HIV testing still ended up contracting the virus and infecting two other men before the disease was detected, according to a new report of the case.
The case underscores the need for adult film workers, and others at risk for HIV infection, to take multiple precautions to prevent HIV transmission, the researchers said. HIV testing cannot detect the virus in very early stages of infection, leaving a window when a person can unknowingly transmit the virus to others.
“Adult film performers and production companies, medical providers and all persons at risk for HIV should be aware that testing alone is not sufficient to prevent HIV transmission,” the researchers said.
In the new case, a period of 22 days elapsed between the adult film star’s last negative HIV test and his positive HIV test. During that time, the man (referred to as “patient A”) had sex with 12 other adult film workers, and three nonwork partners, without using a condom. Of these contacts, one adult film worker and one nonwork partner both tested positive for
The case of a man in the United Kingdom who had Zika virus a few years ago provides even more evidence that the virus can be transmitted through sex, according to a new report.
Researchers found the virus in the man’s semen nearly nine weeks after he became ill, the report said.
“Our data may indicate prolonged presence of [Zika] virus in semen, which, in turn, could indicate a prolonged potential for sexual transmission,” the researchers, from Public Health England, part of the U.K.’s Department of Health, write in an article to be published in the May issue of the journal Emerging Infectious Diseases.
The Zika virus, which is currently spreading in more than 20 countries in Central and South America, is usually transmitted by mosquitoes. But several recent reports suggest that in rare cases, the virus can be transmitted through sex. Earlier this month, health officials said a person in Dallas appeared to have contracted the virus after having sex with a man who had recently traveled to Venezuela, where Zika is spreading.
Health officials are concerned about a
A man wakes up one morning just as he always does but suddenly has flashbacks to a past identity, a name he held 30 years ago.
It sounds like the setup to “The Bourne Identity,” but this bizarre scenario actually played out recently in real life.
A 51-year-old man with a developmental disability living in St. Catharines, Ontario, began having flashbacks of his earlier life. He suddenly remembered who he was: Edgar Latulip, of Kitchener, Ontario. When he told a social worker, she looked up his details and found a missing person’s notice from 1986, CBC reported.
It turned out that Latulip went missing while on his way to Niagara Falls, when he suffered a head injury and forgot who he was. [Top 10 Mysteries of the Mind]
But what causes these cases, and how do people suddenly remember who they are? Although amnesia is a clichéd plot device for mystery novels and soap operas, this type of global amnesia — in which a person forgets everything about his or her life, typically called a fugue state

Around half of end-stage liver disease cases, also known as liver cirrhosis, are caused by alcohol.
Overall, liver cirrhosis is the 10th biggest killer in the US.
Science already has an understanding of how alcohol can directly impact the liver’s health; the metabolic products of the breakdown of alcohol are toxic to the liver.
Additionally, the inflammation that these secondary compounds produce can be harmful to the organ’s functioning.
New research published this week in Cell Host & Microbe shows how a secondary mechanism, involving bacteria in the gut, also plays a significant role in the liver’s downfall.
Dr. Bernd Schnabl and his team at the University of California found that alcohol can suppress antibacterial defense systems within the intestines, causing further damage to the liver.
Mouse guts, lectins and bacteria
REG3B and REG3G lectins are produced by specific cells of the intestinal wall and act as natural antibiotics. Chronic alcohol intake has been found to hinder the production of these proteins.
Reduction in REG3B and REG3G allows bacteria to replicate freely; they are also able to move through the intestinal wall with greater ease. Once on the other
After a story went viral over the weekend linking a pesticide, rather than a virus, to the high rate of the birth defect microcephaly in Brazil, health officials from the United States and Brazil swiftly sought to refute the claim.
The University Network of Environment and Health, a group of doctors and researchers in Argentina, presented the provocative argument February 3. In their report, researchers claimed pyriproxyfen— a pesticide used in drinking water to block mosquito larvae— may be disrupting fetal development when ingested by pregnant women, potentially leading to babies born with microcephaly, The Washington Post reported.
Rates of microcephaly, a birth defect where babies are born with abnormally small heads and underdeveloped brains, have increased in Brazil, with the latest report revealing 4,443 suspected and confirmed cases as the country deals with an outbreak of Zika virus and its suspected link to microcephaly.
American and Brazilian health experts quickly responded to the report, reiterating that the evidence of the link— including the presence of Zika in amniotic fluid and the strong geographic and temporal correlation between the cases and infections— is strong and growing, The Washington Post reported.

Scientists in London have developed an ecological imaging test that may help determine which breast cancers are most likely to be deadly— an analysis that could in turn help doctors tailor individuals’ treatment more effectively.
The Ecosystem Diversity Index fuses a cancer imaging technique and methods used by ecologists to study animal and plant species. In a study published Tuesday in PLOS medicine, scientists at The Institute of Cancer Research, London, who developed the combined test, used the index to distinguish cancer cells from normal cells in tumors, according to a news release. They found that, based on the test, the more complex and diverse breast cancer is, the more likely it may be to advance and cause death. The institute helped fund the research, according to the release.
Study authors analyzed 1,026 samples of untreated breast tumors from three hospitals. They looked at three cell types: cancer cells; immune system lymphocytes; and stromal cells, which produce connective tissue.
They found patients with high-grade tumors that had a diameter larger than 5 centimeters, whose tumors were on the upper end of the Ecosystem Diversity Index, faced a 16 percent five-year survival rate, compared with a
As few as five mutations are enough to make the H5N1 avian influenza virus transmissible via airborne droplets between ferrets, according to a new, highly anticipated report.
Because the flu virus affects ferrets and humans in a similar way, the new findings, appearing in the June 22 issue of the journal Science, may shed light on how likely it is that an avian or “bird flu” virus will become pandemic and spread rapidly between humans.
If a new virus emerged, humans could essentially be defenseless against it.
The paper is the second of two whose publication was banned by the U.S. government, which feared that publishing specifics on a sequence of the H5N1 bird flu might prompt bioterrorists to develop and unleash a pandemic.
In April, however, the controversial ban was lifted and the first paper was published in the journal Nature.
Bruce Alberts, the editor-in-chief of Science, speaking at a press conference Wednesday, said he hoped publication of this and a companion paper “will help to make the world safer by stimulating more scientists and policy makers to focus on preparing defenses [against a pandemic].”
Asked whether the report might increase
Research on a mutated, more contagious form of the bird flu virus can be published in full, U.S. government biosecurity advisers said Friday, despite initial concerns that bioterrorists could use the information to start a pandemic.
The National Science Advisory Board for Biosecurity said two research papers, which have been revised since they were first offered for publication late last year, have been reworked enough so they no longer contain details that might be of value to bioterrorists. The advisers’ recommendation now goes to the U.S. Department of Health and Human Services for a decision, the Associated Press reported.
In December, the advisers recommended against publication of the papers because doing so was potentially risky.
The two studies at the center of the debate were to be published in the journals Science and Nature late last year. The papers, which were funded by the U.S. National Institutes of Health, describe how the virus could mutate relatively easily into a strain that could spread rapidly among humans. The research was done by scientists at the University of Wisconsin and in the Netherlands.
Although the bird flu virus, known as H5N1, rarely infects people, it appears
World Health Organization researchers are reporting an apparent spike in Australia in the number of seasonal influenza cases resistant to Tamiflu, the most commonly used antiviral drug.
The jump in such cases involving the pandemic 2009 A(H1N1) flu strain, also known as swine flu, took place during Australia’s most recent winter: May through August of 2011.
“In 2007/2008, a different A(H1N1) influenza virus developed Tamiflu-resistance,” explained WHO research scientist Aeron C. Hurt, who reported the spike. “On that occasion, it was first detected in large numbers in Europe. However, within 12 months the virus had spread globally, such that virtually every A(H1N1) virus around the world was resistant to this drug,” he explained.
“This previous situation demonstrated the speed and potential for a Tamiflu-resistant virus to spread worldwide,” Hurt added. “Our concern is that this current pandemic 2009 A(H1N1) Tamiflu-resistant virus may also spread globally.”
Hurt, who is based in the Collaborating Centre for Reference and Research on Influenza in North Melbourne, outlined his observations in the Dec. 29 issue of the New England Journal of Medicine.
To explore the question of H1N1-drug resistance,
Figuring out if you have a cold or the flu can be difficult. Learn how to spot the differences.
You have a runny nose, a cough, a fever, and a pounding headache, but what’s making you feel so awful? Figuring out whether you’re dealing with the common cold or the flu is often hard to tell.
Cold vs. Flu Symptoms: Finding the Cause
Both a cold and the flu, or influenza, are respiratory infections, but they’re caused by different viruses. A cold can be caused by any one of more than 200 distinct viruses, while there are only a handful of viruses that cause the flu.
As a general rule, the flu is usually more intense and fierce than the common cold. In some situations, it can be important to know if you have the flu, since it is more likely to lead to serious complications, including pneumonia, bacterial infection, or hospitalization.
Cold vs. Flu Symptoms: Spotting the Differences
Fever, runny nose, fatigue, headache, and muscle aches are symptoms shared by both cold and flu. Although cold and flu share some of the same symptoms, certain indicators are common with each
The various health risks associated with being overweight or obese are well known, but a new study now suggests that this extra weight may also make your annual flu shot less effective.
What’s more, obese and overweight people may be at higher risk for more severe illness if they do catch the flu, according to the findings published online Oct. 25 in the International Journal of Obesity.
Flu vaccines work by causing protective antibodies to develop in the body. In the study, obese, overweight and healthy weight individuals all developed antibodies to flu viruses within the first month after vaccination, but the antibody levels in the blood waned more rapidly among obese and overweight individuals.
Specifically, there was a fourfold decrease in antibody levels 11 months after vaccination in half of the obese patients, compared to one month post-vaccination. By contrast, less than 25 percent of healthy weight participants showed this degree of decrease in their antibody levels after 11 months, the researchers found.
In addition, a type of white blood cell called CD8+ T-cells, which play a key role in priming the body’s immune system, doesn’t work properly in heavier people. When vaccination
FOR IMMEDIATE RELEASE
(Clearwater, Florida) Not many people excitedly anticipate a visit with their dentist. We all associate that dreadful check up with drills and discomfort. But the advent of laser dentistry has truly revolutionized the field. This relatively new technology has propelled the practice of drilling and scraping into a more patient-friendly experience.
Laser dentistry can aid in a myriad of dental procedures:
– Treatment of gum disease by removing inflamed gum tissue
– Exposing partially erupted wisdom teeth
– Removing and exposing gum and bone during crown procedures
– Decreasing bacteria in root canals
– Reducing a patient’s amount of cold and canker sores
– Hastening tooth whitening procedures
The following information about the benefits of laser dentistry will help to reduce any hesitation you might be feeling as you go in for your next check-up.
Below are 5 reasons you should consider using laser dentistry.
1. More Precision
With lasers, a dentist can interact more precisely with tissue and sometimes even remove several layers of cell tissue at a time. A certain kind of laser called the “Erbium” can be highly selective when
Adults who were born with heart defects are at increased risk for stroke, a new study finds. “We knew there was a connection between heart failure and stroke in patients with heart defects, but we were surprised to discover it was the strongest predictor,” said senior study author Dr. Ariane Marelli, a professor of medicine at McGill University in Montreal. However, the study did not prove that heart defects cause stroke. For the study, researchers looked at stroke rates among more than 29,000 adults born with heart defects, and compared them with rates among people in the general population of the province of Quebec, Canada. Those with heart defects were nine to 12 times more likely to suffer an ischemic stroke (blocked blood flow to the brain) before age 55. In addition, they were two to four times more likely to have this type of stroke between the ages of 55 and 64, the investigators found. The strongest predictors of ischemic strokes in adults with heart defects were heart failure, diabetes and recent heart attacks, the study authors said. In addition, adults born with heart defects were five to six times more likely to have a bleeding (“hemorrhagic”)
Over 40,000 civil society observers, government delegation members, heads of state (from over 190 countries), lawyers, negotiators, policymakers, healthcare professionals, scientists, students (the list goes on…) gathered in Paris the last two weeks to come to a global agreement about where we stand, where we are headed, and more specifically, what needs to be done about rapid climate change and its impact on people and planet. That’s no small order.
This was my second time attending the UN Climate Negotiations. I have had the opportunity to work with both civil society organizations (last year at COP20 in Lima, Peru) and government delegations (this year, with the country of Seychelles and other small island developing states). On this global, UN level, I work to advocate for a fair, equitable, and legally binding global agreement, especially in terms of gender justice and human and indigenous rights.
This year, with better planning and more time, I was also able to incorporate the work that I like to be involved with on-the-ground – tropical forests and health care. After spending my summer in Sukadana, I wanted to understand how a program like ASRI fits into the global climate agenda.
Nursing jobs is one of the speediest growing professions in today’s arena for a number of reasons. For starters, the general public of the United States has become more mature and requires more complicated medical treatment. Nursing staff are important in healthcare provider’s establishments, medical centers as well as home care providers to help those getting older people stay healthy. Then, more people happen to be paying for their very own health care insurance and need to take advantage of their plans. Nurses will be needed for primary care physician establishments and also specialist’s offices to manage all those clients which did not been to see a health care professional in several years. Then finally, consumers are starting to identify how essential it is actually to care for themselves. People recognize that nurse practitioners are incredibly well-informed experts and utilize them regarding guidance in addition to health care. Simply because physicians only have a small amount of time with each of the patients, nurse practitioners will be investing a growing amount of time explaining intervention strategies. Anybody who would like to be a part of the fascinating career in medical care needs to know the 2015 nursing rules
Runaway drug prices. “Pharma bro” Martin Shkreli became the most hated man in America in 2015 after he raised the price of an old drug and called a journalist a “moron” on Twitter for asking why. The issue so inflamed the public that a number of presidential candidates joined in the outcry, and a Senate committee launched an investigation into four companies – including Shrkeli’s — for their pricing practices. While Shrekli has been let go from his position as CEO of Turing Pharmaceuticals, the issue of drug pricing continues to be a major concern among consumers. Since then, a number of different interest groups have come up with proposals for different types of pricing schemes, from more federal subsidies for those in need, increasing things like coupons or programs offered by companies to discount prices or even something very radical like tying prices to outcome — meaning that those that extend life the longest would be most expensive.
Is the public outcry so strong that 2016 will be the year when the government or industry comes up with a way to ease the burden on patients?
I was looking around the other day and I ran across a site which offered to sell a pill that they called miracle bust. Obviously it is supposed to make the bust of a woman grow to the size that they desire it to have. Of course they have a beautiful buxom woman in a black bra for visual reference. If you take the pills this is what you shall look like. In fact you have to be skeptical of such claims, but it is not so far fetched when you look at how there have been similar effects in a different drug. It was prescribed for mental illnesses, as an anti psychotic in fact. At the time it was sold by Johnson & Johnson, but they later sold it to some other drug company. At any rate the people who sold this drug made a lot of claims that had no merit and they ended up getting sued for millions upon millions.

Most of us know where our next meal is coming from. Yet our reaction to hunger has not evolved with our convenience-centered world. This is why even the thought of being hungry may send you running to the mini-mart for sustenance. It’s also why some people get so “hangry” when they’re hungry.
The problem: A lot of different factors influence how hungry you feel—many of which have nothing to do with your body’s energy requirements. Your eating habits and schedule, the types of food you swallow, and even how tired or stressed you feel can drive hunger.
These six tips help you control hunger and feel satisfied when you eat. (Lose up to 15 pounds WITHOUT dieting with Eat Clean to Get Lean, our 21-day clean-eating meal plan.)1. Silence your gutWhile fatigue or stress can trick your belly into believing it craves unhealthy junk foods, there are a few proven ways to help chill out its “feed me!” pleas. It may sound counterintuitive, but expending a little energy can help. A yoga practice, gym workout, or even a 10-minute stroll can help quell those fictitious hunger pangs. Keeping food out of sight can help, too.
