RSV is linked to childhood asthma – but we can’t yet say one causes the other

Published

on

As winter approaches in Australia, respiratory viruses are in all places. One of the important culprits is the RSV virus, which has caused over 145,000 infections across the country this yr. Most of them are amongst children under five.

RSV is the leading reason for bronchiolitis and pneumonia (each chest infections) in young children. Every yr no less than one in 200 children children under five are hospitalized with RSV in Australia. Babies lower than six monthsand particularly children under three months of age, are most in danger.

The RSV virus infects respiratory tract and lungswhich causes the mucus in the respiratory tract to turn into very sticky. Young children may experience coughing, wheezing, difficulty respiratory and feeding problems.

Studies indicate that severe RSV infection in infancy can also increase the risk children with asthma. So what evidence is there linking RSV to asthma? And why might this link exist?

Relationship or cause-and-effect relationship?

Asthma is a chronic lung disease that affects: 11% Australians. People with asthma often have difficulty respiratory, coughing, and wheezing. This happens because their airways turn into temporarily narrower, often due to triggers (for instance, viral infections, dust, or pollen). Asthma often begins as wheezing in preschool. But for some people, it begins in maturity.

When we speak about RSV and asthma, it is essential to consider the differences between association and causation. An association occurs when two events often occur together (for instance, smoking and drinking coffee), while a causal relationship occurs when we know that one may cause the other (for instance, smoking and lung cancer). While the association between RSV and asthma is well-established, a causal relationship it has not been proven yet.

To prove a causal relationship, certain criteria should be met. These include a temporal relationship (on this case, RSV infection must occur before asthma) and a plausible explanation (a biological mechanism).

Infants are at biggest risk of RSV infection.

Some evidence suggests that RSV infections change the developing cells in the airways of infants and young children. This could mean that the protective or barrier function of the lining of the airways is altered, predisposing a toddler to turn into sensitized to allergens — when their immune system makes antibodies to something they encounter, similar to grass or dust.

Allergen sensitization is a major risk factor for asthma, so severe RSV infection may contribute to the development of asthma through sensitization to common environmental allergens. This is a possible biological mechanism, but we still need more research to confirm this.

Several studies show an association between severe RSV infection and recurrent wheezing and asthma in later childhood.

But what comes first? one studyChildren under 12 months of age who developed RSV bronchiolitis were followed for six years. Almost half (48%) were diagnosed with asthma before their seventh birthday.

Similarly in one other testChildren hospitalized for RSV infection before the age of two were more likely to develop asthma by the age of 18 than those that weren’t hospitalized.

However, the researchers who conducted twin study concluded that the data were more likely to indicate reverse causation. That is, children with a predisposition to asthma were more likely to develop RSV requiring hospitalization.

We could also be closer to the answer

The pendulum could also be swinging towards causality. Recent findings from South Africa Birth Cohort Study showed that severe RSV infections were related to each recurrent wheezing and subsequent impairment of lung function.

Some prior examination Studies conducted by this group showed that hospitalization for any respiratory infection, and particularly for RSV, was related to recurrent respiratory infections and wheezing. Recurrent wheezing and decreased lung function are predictors of future asthma.

Other last examination Studies of greater than 1,700 children in the United States have shown that avoiding RSV infection in infancy can prevent up to 15% of childhood asthma cases.

Recently, the possibility of vaccinating moms and using monoclonal antibodies to prevent RSV infection has emerged, which is able to probably help answer this query once and for all.

Earlier this yr, nirsewimab (a long-acting monoclonal antibody) became available for infants and young children through state programs in Western Australia, Queensland AND New South Wales. Nirsevimab works barely in another way than the vaccine, but is similarly administered as an injection.

In addition, the RSV vaccine Abrysvo was licensed in Australia this yr to be used while pregnant to protect the baby after birth. It is available to pregnant women to buy privately on prescription from a health care provider, while South Australia recently announced it is going to provide Abrysvo free to pregnant women next yr.

With these measures, hopefully we will see a discount in RSV at a population level in the coming years. If we see a discount in asthma at the same time, this will likely finally answer the query of causality.

Protecting children and communities

Although it is still not known whether RSV causes asthma, RSV and other viral infections will be especially problematic for individuals who have already got asthma. In each cases adults in children with asthma, respiratory diseases of viral origin can have a more severe course and cause an exacerbation asthma symptoms.

RSV It is spread through coughing, sneezing, and shut contact. There are many other viruses that spread in similar ways. Parents will help keep their children and others healthy by encouraging children to cover their mouths and noses when coughing or sneezing and to wash their hands recurrently.

Ensuring that children don’t go to school, daycare, or other children once they are sick helps prevent the spread of many viruses, including RSV. Finally, staying up to date on vaccinations and getting a flu shot yearly could make an enormous difference in our health and the health of those around us.

Women are less likely to undergo cardiopulmonary resuscitation than men. Training on breast mannequins could be helpful

Published

on

By

If someone’s heart suddenly stops beating, this may increasingly have happened minutes of life. Performing cardiopulmonary resuscitation may increase their probabilities of survival. Cardiopulmonary resuscitation keeps blood pumping, delivering oxygen to the brain and vital organs until specialized treatment arrives.

However, research shows that bystanders are less likely to intervene to perform cardiopulmonary resuscitation if the person is a girl. AND latest Australian study analyzed 4,491 cardiac arrest cases between 2017 and 2019 and located that bystanders were more likely to perform CPR on men (74%) than on women (65%).

Could this be partly because CPR training mannequins (so-called dummies) shouldn’t have breasts? Our recent research we checked out mannequins available all over the world to train people to perform CPR and located that 95% of them were flat-chested.

Anatomically, breasts don’t change the cardiopulmonary resuscitation technique. However, they’ll influence whether people try to accomplish that – and hesitation at these key moments could mean the difference between life and death.

Differences in heart health

Cardiovascular diseases – including heart disease, stroke and cardiac arrest – are probably the most common diseases important reason behind death for ladies all over the world.

But if a girl goes into cardiac arrest outside the hospital (meaning her heart stops pumping air properly), that is actually what happens. 10% less likely receive cardiopulmonary resuscitation than a person. Women too less likely survive cardiopulmonary resuscitation and are at greater risk of brain damage following cardiac arrest.

These are just among the many health inequalities experienced by women, in addition to transgender and non-binary people. Compared to men, their symptoms they are more likely to be rejected or misdiagnosed, or it could take longer to receive a diagnosis.

Reluctance of the witness

There can also be growth evidence women are less likely to start cardiopulmonary resuscitation compared to men.

This may be partly due to the concerns of those being accused of sexual harassmentworry may cause damage (in some cases based on the assumption that ladies are more “fragile”) and discomfort related to touching women’s breasts.

Bystanders may also get into trouble recognition the lady has a cardiac arrest.

Even in simulated scenarios, researchers found that interveners were less likely to remove women’s clothing prepare for resuscitationcompared to men. And there have been women less likely to receive Cardiopulmonary resuscitation or defibrillation (an electrical charge to restart the center) – even when the training was in the shape of a web based game that didn’t require touching anyone.

There is evidence of how people behave in resuscitation training scenarios reflects what they do in real emergency situations. This means it is amazingly vital to train people to recognize cardiac arrest and prepare for intervention, no matter gender or body type.

Attached to men’s bodies

Very Cardiopulmonary resuscitation training resources depict male bodies or don’t specify gender. If bodies shouldn’t have breasts, it’s a male default.

For example, the 12 months 2022 test taking a look at CPR training in North, Central, and South America, it was found that nearly all of available mannequins were white (88%), male (94%), and slim (99%).

This research reflects what we see in our work once we train other healthcare professionals to perform cardiopulmonary resuscitation. We noticed that every one the mannequins available for training are flat chested. One of us (Rebecca) had difficulty finding training mannequins with breasts.

Single mannequin with breasts

Our recent research we checked what cardiopulmonary resuscitation mannequins are available and the way diverse they are. In 2023, we identified 20 cardiopulmonary resuscitation mannequins in the worldwide market. Mannequins are often torsos with no head and without arms.

Of the 20 available, five (25%) were sold as “female”, but only considered one of them had breasts. This implies that 95% of obtainable CPR training mannequins were flat-chested.

We also checked out other diversity characteristics, including skin tone and bigger bodies. We found that 65% had more than one skin tone available, but just one had a bigger body. Further research is required on the impact of those elements on bystanders when performing CPR.

Breasts don’t change cardiopulmonary resuscitation technique

Cardiopulmonary resuscitation technique doesn’t change when someone has breasts. The barriers are cultural. And although you could feel uncomfortable, starting cardiopulmonary resuscitation as soon as possible can save your life.

Signs that somebody may have cardiopulmonary resuscitation include not respiration properly or completely or not responding to you.

Perform effective cardiopulmonary resuscitationit’s best to:

  • place the heel of your hand in the middle of your chest

  • place your second hand on top of the primary and interlace your fingers (keep your arms straight)

  • press firmly to a depth of about 5 cm before releasing

  • press your chest with a frequency of 100-120 beats per minute (you may sing a song) in your head to show you how to keep time!)

An example of performing cardiopulmonary resuscitation – using a flat-chest manikin.

What a couple of defibrillator?

You haven’t got to remove someone’s bra to perform CPR. But you could need to accomplish that if a defibrillator is required.

AND defibrillator is a tool that uses an electrical charge to restart the center. An underwired bra may cause minor skin burns when the debrillator pads apply an electrical charge. However, in case you cannot take your bra off, don’t let it delay your care.

What should change?

Our research highlights the necessity for a big selection of breast CPR training mannequins, in addition to a wide range of body sizes.

Training resources need to higher prepare people to intervene and perform CPR on individuals with breasts. We also need greater education on the chance of developing and dying from heart disease in women.

Ant stings can be painful. Here’s how to avoid getting stung this summer (and what to do if it happens)

Published

on

By

The starting of summer is just a couple of days away, and plenty of of us will be looking forward to long, sunny days spent on the beach, by the pool, camping or having a picnic within the park.

Insects love summer too. Most of them right then grow and feed. However, this shared appreciation of the season can sometimes lead to conflict.

Insects have long been preyed upon by many species, including birds, mammals, amphibians, and other insects. Accordingly, quite a lot of defense mechanisms have evolved – perhaps none more familiar to humans than the sting.

Many ants have a stinger on their rear end which they use to deliver venom. It will not be the sting itself that causes pain, but relatively venom. Ant venom accommodates a mix of various chemicals, a few of which have evolved specifically to manipulate the nerve endings in our skin to cause pain.

Let’s take a have a look at the several ant stings chances are you’ll experience this summer in Australia and how to respond.

Bull ants

Bull ants (also often called bulldog ants, jumper ants, or jumper ants) are large for an ant. Some species can grow to length 4 centimeters. They are easily identified by their large eyes, long mandibles (jaws), and aggressive nature.

Their sting is immediate, hot, sharp and unambiguous, similar to that of a honey bee. The intense pain will only last a couple of minutes before being replaced by redness and swelling across the sting site.

There are many differing kinds of bull ants in Australia.

Green-headed ants

Green-headed ants are also called green ants (but not to be confused with green ants). green tree ants northern Australia, which do not sting). Green-headed ants are common and love our lawns.

About Length 6 millimetersthey’re much smaller than bull ants. They can be recognized by their shiny green-purple exoskeleton.

Green-headed ants are frequently less aggressive than bull ants, but they can still deliver a big sting. The pain from a green ant sting can construct up step by step and cause intense, sticky pain.

Fire ants

Fire ants (or imported red fire ants) are native to South America. They were detected first in Brisbane in 2001it probably moved in containers and has since spread across south-east Queensland.

Fire ants are reddish brown and black and range in size from Length 2–6 millimeters.

You will almost certainly encounter fire ants of their nests, which appear like a pile of loose dirt. A hearth ant nest has no obvious entrance, which is way to distinguish it from other similar ant nests.

Disturbing a hearth ant nest will awaken an offended mass of a whole bunch of ants and expose you to being stung.

The initial pain from a single sting seems like an intense, hot itch, although it can be controlled. However, fire ant stings rarely occur in the only digits. One ant can sting multiple times, and plenty of ants can sting one person, which can lead to a whole bunch of stings. A hearth ant sting can cause pus-filled ulcers and scarring in the next days.

If you reside in an area where fire ants are present, it’s price taking a couple of minutes to learn how to do this recognize and report their.

Electric ants

Electric ants is one other nasty random import, coming from Central and South America. Currently limited to Cairns and surroundingsthese are tiny (1.5 millimeters long) yellow ants.

Like fire ants, these ants are frequently defensive, so lots of them will sting without delay. Their sting is more painful than you’ll expect from such a tiny creature. I compare it to being showered with red, hot sparks.

If you think that you see electric ants, please report it Biosecurity in Queensland.

Australian ants should not the worst

You may be surprised to hear that Australian ants don’t even make it to the rostrum when it comes to essentially the most painful ant stings. The winners include: harvester ants (North and South America), which cause severe, sticky pain, comparable to a drill slowly rotating in a muscle – for up to 12 hours.

The gold medal goes to the sting of the South and Central American bullet ant, which has been described How:

Pure, intense, sensible pain. It’s like walking on burning charcoal with a 3-inch nail stuck in your heel.

How to avoid getting stung (and what to do if you do)

Fortunately, the answer is frequently quite simple. Look around before you sit on the bottom or unfolded a picnic blanket, avoiding places where you see ant nests or a lot of foraging ants.

The selection of footwear might also be necessary. In my experience, most stings occur on the feet of those wearing thongs.

If you get stung, generally the situation will improve by itself. The pain often subsides after a couple of minutes (sometimes slightly longer within the case of a green ant sting). The redness, swelling and itching that sometimes follows may last for several days.

In the meantime, if mandatory, ice pack it will help with the pain. If it’s particularly bad, a topical numbing cream containing lidocaine may provide temporary relief. You can get it over-the-counter at a pharmacy.

A small proportion of individuals may experience an allergic response to ant stings. In very severe cases this may include respiratory problems or ingestion. If you or a loved one experiences these symptoms after an ant sting, you need to seek urgent medical attention.
