What is Eastern Encephalomyelitis? Two Mosquito Researchers Explain What’s Behind the Latest Outbreaks

Published

on

Health authorities in the United States are issuing warnings and closing public parks because of a rare but potentially deadly mosquito-borne disease.

This week, a resident of the US state of New Hampshire he died after being hospitalized for Eastern encephalomyelitis. Cases have also been detected in other states.

But what is eastern equine encephalitis? How does it spread? What do horses, as the name suggests, need to do with it? And is it an issue for Australia?

What is Eastern Encephalomyelitis?

Eastern encephalomyelitis It is attributable to a virus that is often found only in parts of eastern America, Central America Down Canada.

Eastern encephalomyelitis virus causes neurological disease, specifically encephalitis (inflammation and swelling of the brain), and is transmitted to humans by mosquito bite. Symptoms might be serious and potentially fatal.

But most individuals bitten by a mosquito carrying the virus won’t have symptoms. Those who do develop the disease have symptoms that include headache, stiff neck, disorientation, seizures, and coma.

About one third Patients with severe symptoms die, and lots of of those that survive suffer from chronic neurological problems.

It’s not only humans who’re in danger from the virus. Horses are too susceptible and, like humans, they may contract deadly encephalitis when bitten by an infected mosquito.

The virus was discovered after the outbreak of the epidemic fatal disease in horses in the New England region of the USA in 1831, hence the reference to a horse disease in the name.

Wild, farmed and captive birds can even be infected with the virus and a few species develop disease. In fact, birds are key to how the virus spreads.

How is Eastern encephalomyelitis virus spread?

Birds – especially passerinea gaggle that features robins, starlings, thrushes and blue jays – are the predominant hosts of the virus.

These birds produce high enough levels of the virus that allow it to contaminate biting mosquitoes and maintain what is called the “transmission cycle.”

Mosquitoes feeding on birds in forested wetlands, especially , allow the virus to flow into amongst the birds. However, this mosquito rarely bites humans, so it is not as necessary in human disease outbreaks.

Mosquitoes feed on each birds and mammals that transmit the virus to humans and horses. These include , and mosquitoes. But once infected, humans and horses don’t spread the virus. This is because they don’t produce high enough levels of the virus to contaminate mosquitoes.

One approach to reduce contact with mosquitoes is to make use of mosquito nets.

How can we limit the spread?

There aren’t any specific treatments for Eastern encephalomyelitis virus infection, or any licensed vaccines to be used in humans. There is a vaccine registered for veterinary use to forestall viral infections in horses.

The predominant strategies to limit human exposure to the virus are personal protective equipment and mosquito control.

Epidemics can have a major impact on communities, not only due to the disease itself, but in addition due to the measures implemented to limit its transmission.

Recent outbreaks have led to the cancellation of out of doors events. Concerns have also been raised about the widespread use of aerial “fogging” to kill mosquitoes, as the chemicals commonly used should not specific to mosquitoes and should pose a risk to other insects.

Some cities have closed park areas evening and asked residents not to depart their homes at night.

Why did the epidemic break out now?

The virus circulates throughout the 12 months in tropical regions. like FloridaIn the northeastern a part of the USA the virus has more sporadic activityHere it is often introduced by migratory birds and is energetic during the warmer months when the mosquito population is high.

This virus has been known for a lot of a long time and has had many outbreaks in North America. One of the last major outbreaks It was in 2019 in several northeastern states of the USA, when 38 human cases (including 12 deaths).

There is evidence that the virus is spreading to latest regions of North America. However, given the sporadic nature of the epidemic, it is difficult to predict when it would occur.

Many aspects could influence future disease outbreaks and the spread of the virus to latest regions, including climate, environmental aspects, mosquito and wildlife activity, and, importantly, humans.

As human contact with mosquitoes that may carry the virus from infected birds increases, the risk to public health increases.

It is possible that human activity near mosquito and bird habitats, including urban encroachment on forested wetlands, increases the risk.

That is why it is so necessary for health services to watch mosquito and virus activity. provide early warning risk of human disease.

Is there a risk to Australia?

There is no evidence that eastern encephalomyelitis virus occurs in Australia and there is no immediate risk of its introduction into this country.

While the mosquitoes are situated in AustraliaTheir role in local viral epidemics in humans and animals is not well understood.

But dozens of various mosquitoes are involved on this process. spread of alphaviruses in Australia. This group includes the eastern encephalomyelitis viruses, in addition to those who occur in Australia, namely Ross River AND Barmah Forest viruses.

It might be assumed that a few of these mosquitoes can transmit the virus, but this has not yet been tested in laboratory experiments.

There is little or no information on how local passerine birds may play a task in establishing virus transmission cycles in Australia. There is also no information on whether native Australian vertebrates, reminiscent of marsupials, would reply to infection.

Considering all available evidence, the risk of the virus spreading to Australia and causing an epidemic is most probably very low.

Are travellers in danger?

The risk of being bitten by a mosquito carrying eastern encephalomyelitis virus is extremely low. However, anyone visiting eastern regions of North America, including the United States and Canada, where the virus could also be present, should take precautions to avoid being bitten by mosquitoes.

Follow guidance from local health authorities. And take steps to avoid areas (especially wooded wetlands) and times when mosquitoes are energetic (often at dawn and dusk). Wear loose clothing with long sleeves and use repellents containing diethyltoluamide (commonly often called DEET), picaridin, or oil of lemon eucalyptus.

These precautions may even protect you from contracting other mosquito-borne viruses you may encounter there, reminiscent of: West Nile Virus.

More than half of party drug users take ADHD medication without a prescription, new study finds

Published

on

By

Each 12 months, the National Drug and Alcohol Research Centre on the University of New South Wales in Sydney surveys a whole bunch of regular drug users in Australia to seek out out understand trends within the use of psychoactive substances throughout the country.

Today we published Report 2024during which 740 people from Australian capital cities who usually use ecstasy or other illegal stimulants were surveyed.

While the first focus of our research is illicit drugs and markets, we also monitor trends within the over-the-counter use of pharmaceutical stimulants, resembling ADHD medications.

This 12 months, 54% of people we spoke to had used pharmaceutical stimulants previously six months after they weren’t prescribed them, the best percentage now we have seen since we began asking people about this kind of drug use in 2007.

What are pharmaceutical stimulants?

Pharmaceutical stimulants include the drug methylphenidate (trade names Concerta and Ritalin), in addition to dexamfetamine and lisdexamfetamine (Vyvanse).

These medications are commonly prescribed for the treatment of attention deficit hyperactivity disorder (ADHD) and narcolepsya chronic neurological disorder that causes excessive sleepiness and sudden sleep attacks through the day.

These drugs work in other ways depending on the kind. However, they treat ADHD by increasing levels of necessary chemicals (neurotransmitters) within the brain, including dopamine and norepinephrine.

However, as with many pharmaceutical substances, people also use these stimulants after they should not prescribed. There is range of reasons someone may select to make use of these medications without a prescription.

Tests University students have shown that these substances are sometimes used to extend alertness, concentration and memory. Studies conducted amongst wider populations have shown that they may also be used experimentor to get high.

All over the world, including in Australiawere significant increases within the prescription of ADHD medications lately, likely on account of increased identification and diagnosis of ADHD. As prescriptions increase, the danger of these substances being diverted to illegal drug markets increases.

Some people may seek pharmaceutical stimulants to extend alertness and concentration.

What we found

The percentage of people using stimulants without a prescription has tripled since monitoring began – from 17% of respondents in 2007 to 54% in 2024. It has remained at a similar level lately (52% in 2022 and 47% in 2023).

Frequency of use remained relatively low. Respondents typically reported using non-prescribed pharmaceutical stimulants monthly or less continuously.

In this study, participants most continuously reported using dexamfetamine, followed by methylphenidate and lisdexamfetamine. Most (79%) said it was “easy” or “very easy” to acquire these substances, just like 2022 and 2023.

Of course, provided that our study focused on regular drug users, the over-the-counter use of pharmaceutical stimulants doesn’t reflect their use in the final population.

In 2022–2023 National Household Drug Strategy Surveygeneral population survey of Australians aged 14 years and over, 2.1% of the population (comparable to about 400,000 people) reported using pharmaceutical stimulants for non-medical purposes within the previous 12 months. This was just like the proportion of people reporting using ecstasy.

What are the risks?

Pharmaceutical stimulants are considered to have a relatively secure toxicity profile. However, like all stimulants, these substances increase activity sympathetic nervous systemwhich controls various functions within the body during times of stress. This in turn increases heart rate, blood pressure and respiration rate.

These changes may cause acute cardiac events (resembling arrhythmias or irregular heartbeats) and, with repeated use of high doses, chronic changes in heart work.

Recent Australian research has documented increase in poisoning involving these substances, although a significant proportion of these seem like intentional poisonings. In the poisonings that involved only pharmaceutical stimulants, the drugs were mostly taken orally, with the median dose being more than ten times the everyday prescribed dose. The commonest symptoms were hypertension (hypertension), tachycardia (fast heart rate), and agitation.

In our study, individuals who took pharmaceutical stimulants most frequently took them in pill form, taking a dose barely higher than that typically prescribed.

However, about one in 4 people reported snorting as a route of administration. This can lead to physical harm, resembling damage to the sinuses, and will increase the potential risks of the drug because it will possibly come into effect faster within the body.

Some pharmaceutical stimulants are “long-acting,” released into the body throughout the day. So there may additionally be a risk of premature re-dosing if people unknowingly use these preparations more than once a day. That is, if people don’t experience desired effects They may take one other dose on the expected time, which can increase the danger of uncomfortable side effects.

Finally, non-prescribed stimulants can have negative effects when taken with other medications. This can include a “masking effect” (for instance, a stimulant may mask the symptoms alcohol poisoning).

So what should we do?

Pharmaceutical stimulants are necessary medications within the treatment of ADHD and narcolepsy, and when used as directed, they’re relatively secure. However, there are additional risks when people use these substances without a prescription.

Harm reduction campaigns that highlight these risks, including differences between formulations, will be useful. Ongoing monitoring, alongside more in-depth investigation of associated harms, can also be key.

Usher’s Groomer Shares His Skin Care Routine That Keeps Him in Shape at 45

Published

Shortly after Labor Day, the consummate entertainer Usher played 4 consecutive sold-out shows in Brooklyn, New York, as a part of his . For two hours each night, he danced, sang, poured drinks for fans (you only needed to be there), and partied with special musical guests, all while his skin glowed. And not simply because he was sweating, although he was sweating loads. But also since the star, who has been around for 3 many years, has flawless skin at age 45. How does he do it?

With proper skincare and the assistance of hairdresser, Lola Okanlawon.

I had the chance, together with a gaggle of journalists and public opinion influencers, to hearken to the speech of Okanlawon, a famous make-up artist and licensed dermatologist DiAnne Davis, MDconcerning the tricks to having an unparalleled skincare routine, and all of it revolves around the suitable products. In addition to dancing with Usher, our presence that evening was also to have a good time the launch of a skincare brand Ceravelatest Eye cream with skin renewing vitamin Cwhich joins their popular Skin Renewing line. Usher uses it, and Davis says it’s best to too.

“Their whole Skin Renewing line really helps target some of the things that you might start to notice as you get a little older,” the plastic surgeon and skincare expert shared. “So maybe you’ve lost a little elasticity, or maybe your skin tone isn’t even, or maybe you’ve noticed a few fine lines and wrinkles here and there. That’s what this Skin Renewing line is all about.”

The key ingredients of the brand new eye cream are hyaluronic acid, which moisturizes, ceramides, which protect and moisturize the skin, caffeine, which reduces puffiness under the eyes, and five percent vitamin C, which brightens the skin across the eyes without irritating it.

(*45*) she says.

Okanlawon visited the artist before ending Usher’s pre-concert styling and opened up about her collaboration with the star, with whom she has been in a relationship for 3 years.

“I take care of all of his skin, from head to toe,” she told us, noting that they’re each fans of Cerave, which she uses often to prep him for the cameras and the massive stage.

“It’s important to have a skin prep routine before you go on stage. This man doesn’t play with his skin or his body,” she shared. “It’s nice to have a man who cares about his skin and cares about his appearance, buys products and asks me about them. ‘Hey, what about this? What about this?'”

The MUA star then delved into the practices and routines that keep her glowing, which include monthly facials (“This is not a game”) and a really, very clean food regimen.

“Of course, we start with a foaming cleanser because I do his stage makeup so that his hairline and certain things stay intact because he sweats a lot,” she says. “If you haven’t seen Usher perform, it’s like a waterfall. So I placed on some makeup that principally won’t come off together with his sweat. Moisturizing foaming cleansing oil It’s amazing since it breaks down product, it breaks down dirt, it breaks down oils, in order that’s definitely where we start.”

Next up is a brand new vitamin C eye cream. Okanlawon received the product ahead of its September launch and has been using it often on the star’s eyes for several months. She says it’s a must have in any skincare routine.

“Usher is a very good, handsome man. But he’s still 45, so eye cream is very important, and eye cream with vitamin C is amazing,” she says. “It’s preventative, so don’t wait until a certain age. Start using eye cream.”

Then they use Vitamin C Serum and finish your pre-makeup workout by moisturizing your body with Cerave Daily Moisturizing Balmwhich apply together.

“We use serum because serum is very important. Vitamin C helps brighten the skin,” she says. “His skin is very elastic because he takes good care of it. It’s easy, he’s easy.”

What Usher does night after night in front of packed audiences is not easy, but with guidance from Okanlawon and Cerave’s Skin Renewing line of beauty products, she all the time looks gorgeous when she does it.

The Way We Think About “Obesity” and Body Weight Is Changing, Here’s Why

Published

on

By

From doctor’s offices to family gatherings, larger people report being bombarded unsolicited advice about their eating and exercise habits. The underlying message? “They just need to lose weight” to solve almost any health problem.

Society’s give attention to weight has shaped the best way most Australians view health and body weight, which frequently pushes them towards unhealthy thoughts and behaviors in pursuit of the “perfect” figure.

However, the best way society views obesity and body weight is changing, and these changes are being confirmed by science.


*


Policymakers and health researchers are increasingly recognizing the harmful effects stigmatizing language and attitude towards individuals with a bigger physique.

Let’s have a look at how attitudes towards obesity have modified through the years and what this implies for public health and healthcare in Australia.

From Personal Responsibility to Complex Chronic Illness

Until recently, weight control was it will likely be considered a private responsibilityObesity was believed to be the results of poor eating regimen and lack of physical activity, coupled with personal and moral failure.

This narrative was reflected in public health policy, which used phrases similar to “he was obese“and the “epidemic of o*c*lness”. It has been shown that such language reinforce negative stereotypes people with larger builds as “lazy” and lacking willpower.

These stereotypes result in stigmatization and weight discrimination, which is still common today. Health professionals similar to dietitians report that Weight stigma (from other people and internally) is a standard and ongoing challenge that ladies need to cope with throughout their careers.

The narrative around personal responsibility has modified lately because it begins to think about broader determinants of health. Research has identified a spread of psychological, social, biological and systemic aspects contribute to rising rates of obesity, similar to socioeconomic status, genetics, medications and environment.

As a result, public health experts consider that is not any longer appropriate use language that refers to obesity as a “lifestyle” issue.

Until recently, weight management was seen as a private responsibility.
World Obesity Federation

Professionals throughout medicine, psychology and dietetics additionally they responded by updating their language standards to prioritize person-first language (for instance, “person living with o*b*lihood”), recognizing a shift away from viewing o*b*lihood as a private failure.

In 2014, the American Medical Association of the United States classified obesity as a chronic diseasecontrary to the recommendations of the Science and Public Health Committee. The decision has sparked widespread dissatisfaction and debate, with claims that it causes unnecessary discrimination and pathologizes normal changes within the human body over time.

The debate continues here in Australiabut no classification has yet been made.

Weight-focused and weight-sensitive narratives

Recent policy documents in Australia similar to National Anti-Obesity Strategy 2022–2032acknowledge the broader perspective of o*b*st. But the policy and practice in Australia remain mainly focused on weight. They encourage weight reduction as a health goal and recommend deliberately avoiding weight gain.

Weight-Focused Approaches to Health They were criticized for the dearth of long-term (longer than five years) evidence of their effectiveness and for causing unintended effects.

Rather than promoting health, weight-focused approaches could cause harm, similar to increased weight stigma and weight cycling (repeated weight reduction and regain). Both weight mark AND weight cycles are related to negative long-term effects on physical and mental health.

Weight-sensitive approaches to health are gaining popularity instead approach that supports people to eat healthily and exercise repeatedly, no matter their desire to shed weight. This approach goals to enhance access to health care and has been shown to enhance overall physical and mental health.

Approaches similar to Health at every size and intuitive eating are key examples of promoting health and wellness without specializing in weight.

Weight-sensitive approaches have he was met with criticismHowever, there are concerns that these approaches will not be supported by empirical evidence and might not be suitable for people needing support with weight management.

What does this mean for us?

While our views on obesity are always changing, it is crucial to hearken to plus-size people and ensure they’ve equal, protected and satisfactory access to healthcare.

Advocates like Size Inclusive Health Australia recommending actions to cut back weight-related stigma and discrimination in order that health is inclusive of all body shapes and sizes.

There are guidelines and recommendations on counter weight stigma and adopt a weight-sensitive approach to health, similar to: Size-sensitive health promotion guidelines and Eating Disorder Safety Guidelines.

Policy, research and practice should proceed to synthesise and understand the evidence surrounding weight-sensitive approaches, in keeping with changing narratives around weight and health. This will support the design, implementation and evaluation of weight-sensitive initiatives in Australia.
