What are dust mites and how do I know if I am allergic to them?

Published

on

People often think they’ve an allergy house dust. But with 20% of Australians Allergy victims, a lot of them are actually allergic to microscopic house dust mites.

House dust mites belong to the identical family as spiders and ticks. They measure only 0.2-0.3 mm, and there are 50 pieces on one pin head. They live for 65–100 days, and females lay 60–100 eggs during their lives.

About 50 dust mites can fit on one head of a pin.

House dust mites love moderate climates and humidity. They feed on skin cells that we and animals shed, in addition to mold, which they digest using special enzymes. These enzymes are excreted within the feces 20 times a day. They also shed pieces of their exoskeletons.

All of those fragments trigger allergies in people affected by the sort of allergic rhinitis (also often known as hay fever).

What are the symptoms?

When people allergic to house dust mites inhale the allergens, they penetrate the mucous membranes of the respiratory tract and eyes. Their body recognizes allergens as a threat, releasing chemicals, including one called histamine.

This causes symptoms corresponding to a runny nose, itchy nose, eyes and throat, sneezing, coughing and a sense of mucus at the back of the throat (so-called postnasal drip).

People with the sort of allergy normally breathe through their mouths, snore, rub their nose continually (making a nasal wrinkle called the “mite greeting”), and have dark circles under their eyes.

Allergy to house dust mites can even cause poor sleep, constant fatigue, decreased concentration at work or school and lower quality of life.

For people affected by eczema, a damaged skin barrier can allow house dust mite proteins to enter the skin. This stimulates the skin’s immune cells release chemicals which make already dilated skin redder, more painful and itchy, especially in children.

Symptoms of allergy to house dust mites occur all 12 months round and often worsen after going to bed and waking up within the morning. However, people affected by allergies to house dust mites and pollen find that their year-round symptoms worsen in spring.

How is it diagnosed?

Dust mite allergy symptoms often worsen for months and even years before people seek help. However, accurate diagnosis not only means access to appropriate treatment, it’s also essential to minimize exposure.

Doctors and nurses can order: blood test to check for allergies to house dust mites.

Alternatively, healthcare providers with specialized allergy training can perform skin tests. This involves placing drops of allergens in your arm together with positive and negative “controls”. After quarter-hour, individuals who test positive can have a mark that appears like a mosquito bite.

How is it treated?

Treatment options include one or a mix of:

  • every day non-sedating antihistamines
  • steroid nasal spray
  • allergy eye drops.

Your health care skilled will work with you to develop it rhinitis (hay fever) treatment plan. to reduce symptoms. If you employ a nasal spray, your doctor will do this show you how to use itbecause people often use it incorrectly.

If you have got too asthma or eczema aggravated by mites, your doctor will adjust your treatment asthma motion plan Or eczema care plan appropriately.

If severe symptoms occur, there may be a long-term option immunotherapy. This is meant to regularly disable the immune system’s ability to recognize house dust mites as a harmful allergen.

Immunotherapy involves taking a every day sublingual tablet under the tongue or a series of injections. Injections require monthly visits for 3 years, after an initial weekly preparation phase.

They are effective, but expensive (and time-consuming). Therefore, it is necessary to weigh the potential advantages and drawbacks together with your doctor.

How to minimize the danger of house dust mites?

There are also vital allergy minimization measures you’ll be able to take to reduce the quantity of allergens in your property.

Every week wash bedding and pajamas in hot water (over 60°C). This deletes House dust mite eggs and stays.

Choose blankets, covers or duvets that will be washed in hot water at a temperature above 60°C. Alternatively, inexpensive waterproof or airtight covers can protect against dust mites.

If you’ll be able to, favor blinds and picket floors over curtains and carpets. Dust blinds and surfaces weekly with a moist cloth and dust with a mask or have another person do it, as dust mites can turn into airborne during cleansing.

However, beware of pricy products with large marketing budgets and little evidence to support their use. For example, a brand new mattress will all the time be free from house dust mites. But as you proceed to sleep, the dust mite life cycle may begin.

Mattress protectors and toppers are commonly described as “hypoallergenic”, “anti-allergic” or “allergy-free”. However, their pore size just isn’t sufficiently small to prevent dust mites and their excrement from entering or exfoliating the skin.

Sprays that are intended to kill dust mites require simply enough spray to penetrate the product, which is probably going to get wet, may smell like a twig, and, if not dried properly, may develop mold.

Finally, the claim that expensive vacuum cleaners can remove all house dust mites is unfounded.

The family of Tire Sampson, the 14-yr-old who tragically died on an amusement park ride in Orlando, Florida, in 2022, has been awarded $310 million in a civil lawsuit.

Tire, who was visiting ICON Park along with his family on March 24, 2022, fell from the FreeFall drop tower. Although he was taken to a nearby hospital, he didn’t survive his injuries.

Now, greater than two years later, a jury has held the vehicle manufacturer, Austria-based Funtime Handels, responsible for the accident and awarded the Tire family $310 million. According to reports from local news stations WFTV AND KSDKthe jury reached its verdict after about an hour of deliberation.

Tyre’s parents will each receive $155 million, according to attorney spokesman Michael Haggard.

Attorneys Ben Crump and Natalie Jackson, who represented Tyre’s family, shared their thoughts on this landmark decision via X (formerly Twitter). “This ruling is a step forward in holding corporations accountable for the safety of their products,” they said in a statement.

Lawyers stressed that Tyre’s death was attributable to “gross negligence and a failure to put safety before profits.” They added that the ride’s manufacturer had “neglected its duty to protect passengers” and that the substantial award ensured it could “face the consequences of its decisions.”

Crump and Jackson said they hope the result will encourage change throughout the theme park industry. “We hope this will spur the entire industry to enforce more stringent safety measures,” they said. “Tire heritage will provide a safer future for drivers around the world.”

An investigation previously found that Tyre’s harness was locked through the descent, but he dislodged from his seat through the 430-foot fall when the magnets engaged. Tire’s death was ruled the result of “multiple injuries and trauma.”

ICON Park said at the time that it could “fully cooperate” with the authorities.

Tireless HIV/AIDS advocate A. Cornelius Baker dies

Published

By

HIV/AIDS Advocate, A. Cornelius Baker


A. Cornelius Baker, a tireless advocate of HIV and AIDS testing, research and vaccination, died Nov. 8 at his home in Washington, D.C., of hypertensive, atherosclerotic heart problems, in response to his partner, Gregory Nevins.

As previously reported, Baker was an early supporter for people living with HIV and AIDS within the Nineteen Eighties, when misinformation and fear-mongering in regards to the disease were rampant.

According to Douglas M. Brooks, director of the Office of National AIDS Policy under President Obama, it was Baker’s Christian faith that guided him toward compassion for others.

“He was very kind, very warm and inclusive – his circles, both professional and personal, were the most diverse I have ever seen, and he was guided by his Christian values,” Brooks told the outlet. “His ferocity was on display when people were marginalized, rejected or forgotten.”

In 1995, when he was executive director of the National AIDS Association, Baker pushed for June 27 to be designated National HIV Testing Day.

In 2012, he later wrote on the web site of the Global Health Advisor for which he was a technical advisor that: “These efforts were intended to help reduce the stigma associated with HIV testing and normalize it as part of regular screening.”

Baker also feared that men like himself, black gay men, and other men from marginalized communities were disproportionately affected by HIV and AIDS.

Baker pressured the Clinton administration to incorporate black and Latino people in clinical drug trials, and in 1994 he pointedly told the Clinton administration that he was bored with hearing guarantees but seeing no motion.

According to Lambda Legal CEO Kevin Jennings, yes that daring attitude that defines Baker’s legacy in the world of ​​HIV/AIDS promotion.

“Cornelius was a legendary leader in the fight for equality for LGBTQ+ people and all people living with HIV,” Jennings said in a press release. “In the more than twenty years that I knew him, I was continually impressed not only by how effective he was as a leader, but also by how he managed to strike the balance between being fierce and kind at the same time. His loss is devastating.”

Jennings continued: “Cornelius’ leadership can’t be overstated. For many years, he was one in all the nation’s leading HIV/AIDS warriors, working locally, nationally and internationally. No matter where he went, he proudly supported the HIV/AIDS community from the Nineteen Eighties until his death, serving in various positions including the Department of Health and Human Services, the National Association of Persons with Disabilities AIDS, and the Whitman-Walker Clinic . Jennings explained.

Jennings concluded: “His career also included several honors, including being the first recipient of the American Foundation for AIDS Research Foundation’s organization-building Courage Award. Our communities have lost a pillar in Cornelius, and as we mourn his death, we will be forever grateful for his decades of service to the community.”

Kaye Hayes, deputy assistant secretary for communicable diseases and director of the Office of Infectious Diseases and HIV/AIDS Policy, in her comment about his legacy, she called Baker “the North Star.”.

“It is difficult to overstate the impact his loss had on public health, the HIV/AIDS community or the place he held in my heart personally,” Hayes told Hiv.gov. “He was pushing us, charging us, pulling us, pushing us. With his unwavering commitment to the HIV movement, he represented the north star, constructing coalitions across sectors and dealing with leaders across the political spectrum to deal with health disparities and advocate for access to HIV treatment and look after all. He said, “The work isn’t done, the charge is still there, move on – you know what you have to do.” It’s in my ear and in my heart in the case of this job.

Hayes added: “His death is a significant loss to the public health community and to the many others who benefited from Cornelius’ vigilance. His legacy will continue to inspire and motivate us all.”

Baker is survived by his mother, Shirley Baker; his partner Nevins, who can be senior counsel at Lambda Legal; his sisters Chandrika Baker, Nadine Wallace and Yavodka Bishop; in addition to his two brothers, Kareem and Roosevelt Dowdell; along with the larger HIV/AIDS advocacy community.

Bovaer is added to cow feed to reduce methane emissions. Does it pass into milk and meat? And is it harmful to humans?

Published

on

By

There are growing concerns in regards to the use of feed supplements, Bowar 10to reduce methane production in cows.

Bovaer 10 consists of silicon dioxide (mainly sand), propylene glycol (food stabilizer approved by Food Safety Australia New Zealand) and lively substance 3-nitrooxypropanol (3-NOP).

There has been an enormous amount of misinformation in regards to the safety of 3-NOP, with some milk from herds fed this additive being labeled “Frankenmilk”. Others feared it could get to humans through beef.

The most significant thing is that 3-NOP is secure. Let’s clear up some major misconceptions.

Why do we want to limit methane production?

In our attempts to limit global warming, we’ve placed the best emphasis on CO₂ because the major man-made greenhouse gas. But methane is also a greenhouse gas, and although we produce less of it, it is: a much stronger greenhouse gas than CO₂.

Agriculture is the largest a man-made source of methane. As cattle herds expand to meet our growing demand for meat and milk, reducing methane production from cows is a vital way to reduce greenhouse gas emissions.

There are several ways to do that. Stopping bacteria within the stomachs of cows that produce methane one approach is to produce methane.

The methane produced by cows and sheep doesn’t come from the animals themselves, but from the microbes living of their digestive systems. 3-NO stop the enzymes that perform the last step of methane synthesis in these microorganisms.

3-NOP is not the one compound tested as a feed additive. Australian product based on seaweed, Rumin8for instance, it is also in development. Saponins, soap-like chemicals present in plants, and essential oils as well has been examined.

However, 3-NOP is currently one of the popular effective treatments.

But is not it poison?

There are concerns on social media that Bovaer is “poisoning our food.”

But, as we are saying in toxicology, it’s the dose that makes the poison. For example, arsenic is deadly 2–20 milligrams per kilogram of body weight.

In contrast, 3-NOP was not lethal on the doses utilized in safety studies, up to 600 mg 3-NOP per kg body weight. At a dose of 100 mg per kg body weight in rats, it didn’t cause any adversarial effects.

What about reproductive issues?

The effect of 3-NOP on the reproductive organs has generated numerous commentary.

Studies in rats and cows showed that doses of 300–500 mg per kg body weight caused: contraction of the ovaries and testicles.

In comparison, to achieve the identical exposure in humans, a 70 kg human would want to eat 21–35 grams (about 2 tablespoons) of pure 3-NOP every day for a lot of weeks to see this effect.

No human will likely be exposed to this amount because 3-NOP doesn’t pass into milk – is fully metabolized within the cow’s intestines.

No cow will likely be exposed to these levels either.

What about cancer?

3-NOP is not genotoxic or mutagenicwhich implies it cannot damage DNA. Thus, the results of 3-NOP are dose-limited, meaning that small doses will not be harmful, while very high doses are (unlike radiation where there is no secure dose).

Scientists found that at a dose of 300 mg per kilogram of body weight benign tumors of the small intestine of female ratsbut not male rats, after 2 years of every day consumption. At a dose of 100 mg 3-NOP per kg body weight, no tumors were observed.

Cows eat lower than 2 grams of Bovaer 10 per day (of which only 10% or 0.2 grams is 3-NOP). This is about 1,000 times lower than the appropriate every day intake 1 mg 3-NOP per kg body weight per day for a cow weighing 450 kg.

This level of consumption will likely be not the result in cancer or any of them other adversarial effects.

So how much are people exposed to?

Milk and meat consumers will likely be exposed to zero 3-NOP. 3-NOP doesn’t penetrate milk and meat: is completely metabolized within the cow’s intestines.

Farmers could also be exposed to small amounts of the feed additive, and industrial employees producing 3-NOP will potentially be exposed to larger amounts. Farmers and industrial employees already wear personal protective equipment to reduce exposure to other agricultural chemicals – and it is advisable to do that with Bovear 10 as well.

How widely has it been tested?

3-NOP has been in development for 15 years and has been subject to multiple reviews by European Food Safety Authority, UK Food Safety Authority AND others.

It has been extensively tested over months of exposure to cattle and has produced no unintended effects. Some studies actually say so improves the standard of milk and meat.

Bovaer was approved for use in dairy cattle by the European Union from 2022 and Japan in 2024. It is also utilized in many other countries, including: in beef products, amongst others Australia.

A really small amount of 3-NOP enters the environment (lower than 0.2% of the dose taken), no accumulates and is easily decomposed subsequently, it doesn’t pose a threat to the environment.

Since humans will not be exposed to 3-NOP through milk and meat, long-term exposure is not an issue.

What does Bill Gates have to do with this?

Bill Gates has invested in a distinct feed processing method for methane, Australian seaweed-based Rumin8. But he has nothing to do with Bovaer 10.

The Bill & Melinda Gates Foundation awarded research grants to the corporate producing 3-NOP for malaria control researchnot for 3-NOP.

The bottom line is that adding 3-NOP to animal feed doesn’t pose any risk to consumers, animals or the environment.
