Fewer Scientists Are Studying Insects. Here ’s Why That’s So Dangerous

Wed, 14 Feb 2018 19:30:26 +0100

In the summer of 2016, Jerome Goddard, a medical entomologist in Mississippi, received an email from the U.S. Centers for Disease Control and Prevention (CDC) with a desperate ask. The agency was conducting an “urgent” search for insect scientists around the U.S. who could take up to a six-month paid leave from work to help the CDC fight the Zika outbreak in the U.S., and possibly respond to areas with local transmission if needed. “That’s how bad it is—they need to borrow someone,” says Goddard, an extension professor of medical entomology at Mississippi State University. “We can’t find people to investigate an outbreak.” Medical entomology—the study of insects and arthropods that impact human health—has been a shrinking f...

Memory loss from West Nile virus may be preventable

Tue, 16 Jan 2018 05:00:00 +0100

(Washington University School of Medicine) More than 10,000 people in the United States are living with memory loss and other persistent neurological problems that occur after West Nile virus infects the brain. Now, a new study in mice suggests that such ongoing neurological deficits may be due to unresolved inflammation that hinders the brain's ability to repair damaged neurons and grow new ones. When the inflammation was reduced by treatment with an arthritis drug, the animals' ability to learn and remember remained sharp after West Nile disease.

Zika virus may be useful in treating brain tumours

Wed, 06 Sep 2017 17:00:00 +0100

Conclusion This is an interesting piece of research that shows how knowledge in one field of medicine can sometimes be applied to another field with surprising results. But it's important to be realistic about the stage of research. This is very much a "proof of concept" study, and tests on cells, tissues and mice don't necessarily translate into a safe and effective treatment for humans. The study has several limitations, but the fact the treatment so far hasn't been tested on humans is the most important. For one thing, Zika virus doesn't naturally infect mice, so researchers had to use a specially engineered virus that's different from the virus that infects humans. Also, the glioma tumours in mice were taken from mouse models, so they weren't the same as human glioma tumours....

The World Is Not Ready for the Next Pandemic

Thu, 04 May 2017 11:48:04 +0100

Across China, the virus that could spark the next pandemic is already circulating. It’s a bird flu called H7N9, and true to its name, it mostly infects poultry. Lately, however, it’s started jumping from chickens to humans more readily–bad news, because the virus is a killer. During a recent spike, 88% of people infected got pneumonia, three-quarters ended up in intensive care with severe respiratory problems, and 41% died. What H7N9 can’t do–yet–is spread easily from person to person, but experts know that could change. The longer the virus spends in humans, the better the chance that it might mutate to become more contagious–and once that happens, it’s only a matter of time before it hops a plane out of China and onto foreign soil, where it...

[Report] Enhancement of Zika virus pathogenesis by preexisting antiflavivirus immunity

Thu, 13 Apr 2017 22:11:05 +0100

Zika virus (ZIKV) is spreading rapidly into regions around the world where other flaviviruses, such as dengue virus (DENV) and West Nile virus (WNV), are endemic. Antibody-dependent enhancement has been implicated in more severe forms of flavivirus disease, but whether this also applies to ZIKV infection is unclear. Using convalescent plasma from DENV- and WNV-infected individuals, we found substantial enhancement of ZIKV infection in vitro that was mediated through immunoglobulin G engagement of Fcγ receptors. Administration of DENV- or WNV-convalescent plasma into ZIKV-susceptible mice resulted in increased morbidity—including fever, viremia, and viral loads in spinal cord and testes—and increased mortality. Antibody-dependent enhancement may explain the severe disease manifestation...

5 Ways The Zika Virus Is Here To Stay

Wed, 04 Jan 2017 18:46:09 +0100

Zika virus’ status as a global health threat may officially be over, but the disease’s impact is far from contained.  The World Health Organization decided in November to end its designation of Zika virus as a public health emergency, but that doesn’t mean that Zika virus has disappeared, explained Dr. Carlos Pardo-Villamizar, a clinical neurologist with an expertise in infectious disorders at Johns Hopkins Medicine. Alongside pressing concerns about how to prevent a resurgence of the disease, health care systems in Brazil and other countries that saw births of babies infected with the disease in utero now have to find a way to fund and facilitate expensive, intensive therapy and care for thousands of children who have been born with birth defects. As the WHO itself ...

Aethlon ’ s blood filtration device as broad countermeasure for infectious diseases

Fri, 18 Nov 2016 15:02:42 +0100

In the midst of a devastating global crisis 2 years ago, a Ugandan physician was infected with Ebola in Sierra Leone as he was treating patients. He was hospitalized at the Frankfurt University Hospital and 12 days later he was unconscious, suffering from multiple organ failure. By the time Aethlon Medical (NSDQ:AEMD) got permission to use its Hemopurifier device, the doctor required mechanical ventilation, continuous dialysis and vasopressor medications. After almost 7 hours of treatment with the single cartridge blood filtration device, the patient’s viral load dropped from 400,000 virus copies per milliliter of blood to 1,000 copies per milliliter. The doctor eventually made a full recovery. Aethlon CEO Jim Joyce told MassDevice.com that this story is a powerful example of wha...

Zika's Rapid Rise and the Limp Global Response Reveal Dire Global Health Challenges

Fri, 04 Nov 2016 15:25:39 +0100

With cases rising in Florida, Singapore, Vietnam and Trinidad and Tobago, the Zika virus pandemic is raising public concern in regions across the globe, including the U.S., where about 80 percent of Americans are aware of it but only 40 percent understand how it is actually transmitted. This raises a host of questions not only about the clinical and epidemiological scope of the outbreak, but also about the ability of citizens, public health authorities and politicians at all levels to adequately deal with it.  So far, the response has been slow and the challenge remains serious and unpredictable. We need to understand an organism that the director of the Centers for Disease Control’s division of vector-borne diseases called “the most complicated issue CDC has ever fac...

A Mysterious Neurological Condition Is Paralyzing Children

Thu, 03 Nov 2016 19:57:49 +0100

The U.S. Centers for Disease Control and Prevention is investigating the rise of a rare polio-like illness that tends to strike children. Acute flaccid myelitis, a condition that affects the nervous system, has sickened 89 people across 33 states so far this year, and doctors aren’t sure what causes it.  Scientists still only have a preliminary understanding of how AFM affects children, but it appears to affect muscle tone, sometimes to the point of long-term paralysis.   Symptoms include sudden weakness in the limbs, loss of muscle strength and decreased reflexes. Other signs of the disease include droopy eyes, slurred speech, or difficulty swallowing. In particular, there’s a wide spectrum of muscle weakness, ranging from mild weakness in a single limb to almost com...



Louisiana Sees More Cases of West Nile Virus

Thu, 03 Nov 2016 12:30:00 +0100

“Photo” by FotoshopTofs is licensed under CC0. The Louisiana Department of Health reported this week that it has seen 36 cases of West Nile virus in Louisiana so far in 2016. Six more cases were reported within the last two weeks. Of those diagnosed with West Nile virus, 15 were asymptomatic or fever cases, a mild illness. Twenty-one were neuroinvasive, a very severe case which can lead to brain damage and even death. Like Zika virus, West Nile virus is a mosquito-transmitted disease. Many people (70 – 80 percent according to the Centers for Disease Control and Prevention) who contract the disease do not experience any symptoms. However, symptoms do include, fever, headache, body aches, joint aches, vomiting, diarrhea, rash, neck stiffness, tremors, seizure, paralysis, disor...



Three New Mexicans Diagnosed with West Nile Virus

What 1989 And The Golden Girls Tell Us About Medicine Today

Fri, 23 Sep 2016 19:34:17 +0100

Today, 1989 may be most associated with Taylor Swift: It is the album that won her a second Grammy for Album of the Year. Not only that, it happens to be the year Swift was born--such a long, long time ago! People under 35 have no personal memory of 1980s pop culture, which is ironic since Swift's album in part pays homage to it. In the real 1989 (no offense to Swift and the 10 co-producers who made the album), all sorts of revolutions took place: Mr. Gorbachev tore down that pesky wall, for example. America's greatest antagonist, the Soviet Union, collapsed in 1989. Brazil conducted its first democratic presidential election since 1960. And so on. Today, it's hard to say whether America's greatest existential threat may be Vladimir Putin or his Number-One American Fan, Donald Trump...



So THAT'S When You Should See A Doctor For A Bug Bite

Thu, 01 Sep 2016 21:40:22 +0100

The Question: When does a bug bite require serious medical attention? The Answer: Sometimes that pesky mosquito bite just needs a little hydrocortisone cream and time to heal. But occasionally, it’s not so simple. While most bug bites and stings are harmless, some can be dangerous if not treated properly — especially if you have an undiagnosed allergy to a particular bug venom or if that bug is a disease carrier. The summer months seem to be stocked with extra critters crawling and buzzing around us, upping the chances that you, a friend or a family member might need a dermatologist’s expertise. Here’s how the experts determine the difference between a nuisance and a health concern that requires attention. One of the first steps to differentiating between a ...



FDA To Screen All Donated Blood For The Zika Virus

Mon, 29 Aug 2016 16:11:15 +0100

By Julie Steenhuysen and Letitia Stein CHICAGO/TAMPA, Fla. (Reuters) - The U.S. Food and Drug Administration recommended on Friday that all blood donated in the United States and its territories be tested for Zika virus, as it moves to prevent transmission of the virus through the blood supply. The agency said its decision to expand blood screening in the United States was based on concerns about more cases of local transmission in Florida, the growing number of travel-related infections and concerns that Zika-tainted blood could unwittingly be given to a pregnant woman, putting her unborn baby at risk of severe birth defects. “The transfusion of a pregnant woman with blood infected with the Zika virus could have terrible consequences,” Peter Marks, director of the FDA’s ...

What's Really Inside Your Bug Spray?

Mon, 11 Jul 2016 12:22:18 +0100

It’s the height of summer — and if you’ve been spending more time outdoors lately, chances are you’ve got a few (or more) bug bites to show for your time in the sun. And while bites from pests are an inevitable part of summer, it’s important to reduce your risk of bug bites from mosquitoes and ticks. That’s because several species of these insects can carry dangerous disease, including Lyme disease and West Nile virus. “The most effective way to avoid West Nile virus disease is to prevent mosquito bites,” wrote the CDC in their summer health guidelines. “Repellents containing DEET, picaridin, IR3535, and some oil of lemon eucalyptus and para-menthane-diol products provide longer-lasting protection.” The consumer advocacy org...

By Drs. David Niesel and Norbert Herzog, Medical Discovery News Have you noticed in the past few years, we seem to be continuously assaulted by microbial menaces? Some years back it was SARS, which set off a global panic. People were screened for fevers at many major international airports. Then came the West Nile virus, which started from a single case in New York and in a matter of years marched across the U.S. Who can forget the avian flu or swine flu, which happened around the same time? More recently, the MERS virus has emerged, with outbreaks in the Arabian Peninsula and then whole villages in Korea. We are just now reaching the end of the devastating Ebola outbreak in West Africa. Even if you're not an alarmist, it's hard to ignore the threat of these new microbial menaces. The late...
