XEC is now in Australia. Here’s what we know about this hybrid variant of the SARS-CoV-2 virus

Published

on

In the nearly five years since the emergence of the Covid-19 virus, you would be forgiven for forgetting the number of latest variants we’ve seen. Some have had a greater impact than others, but documented by virologists hundreds.

The latest variant that is making headlines it’s called XEC. This omicron subvariant has been reported mainly in the northern hemisphere, but is now occurring detected in Australia too.

So what do we know about XEC?

Is Covid still relevant?

People are less more likely to test for Covid-19 and fewer more likely to report it. Enthusiasm for track the virus generally decreasing.

However, Australia continues to gather data and report Covid data. Although the number of cases is more likely to be much higher than documented (approx This 12 months already 275,000), we can still tell when we see significant waves in comparison with periods of lower activity.

Australia has recorded its latest peak in Covid-19 cases of the 12 months June 2024. Since then, the number of cases has been declining.

But SARS-CoV-2, the virus that causes Covid, is actually still around.

What variants are currently in circulation?

Main Covid variants currently circulating around the world are BA.2.86, JN.1, KP.2, KP.3 and XEC. They are all descendants of Omicron.

This is the first time the XEC variant has been detected in Italy in May 2024, the World Health Organization (WHO) described it as a variant “under monitoring”in September.

From the moment of detection XEC has spread to over 27 countries in Europe, North America and Asia. As of mid-September, the highest number of cases were found in countries equivalent to the United States, Germany, France, the United Kingdom and Denmark.

XEC is currently catching up 20% of cases in Germany, 12% in the UK AND in the USA about 6%..

Although XEC stays a minority variant worldwide, it appears to have a growth advantage over other circulating variants. We don’t know why yet, but reports suggest it might be possible spread more easily than other variants.

For this reason, it is predicted that XEC may turn into the dominant variant worldwide in the coming months.

How about Australia?

Latest Australian Respiratory Surveillance Report it has been noted that an increasing proportion of sequenced XECs has been observed recently.

In Australia, 329 SARS-CoV-2 sequences collected from August 26 to September 22 were uploaded to the website AusTrakkaAustralia’s National Genomics Surveillance Platform for Covid-19.

The most sequences (301 of 329, or 91.5%) are JN.1 sublines, including KP.2 (17 of 301) and KP.3 (236 of 301). The remaining 8.5% (28 of 329) were recombinants consisting of a number of omicron sublineages, including XEC.

Estimates based on data from GISAID, the international repository of viral sequences, suggest that XEC is catching up about 5% of cases in Australia or 16 of 314 samples were sequenced.

Queensland reported the highest rates over the last 30 days (8% or eight of 96 sequences), followed by South Australia (5% or five of 93), Victoria (5% or one of 20) and New South Wales (3% or two out of 71). WA recorded zero sequences out of 34. No data was available for other states and territories.

What do we know about XEC? What is a recombinant?

The XEC variant is believed to be the recombinant descendant of two previously identified omicron subvariants, KS.1.1 and KP.3.3. Recombinant variants arise when two different variants infect a number at the same time, allowing the viruses to swap genetic information. This results in the emergence of a brand new variant having features of each “parent” lines.

KS.1.1 belongs to a bunch commonly often called “FLiRT” variantswhile KP.3.3 is one of the “FLuQE” variants. Both of these groups of variants have contributed to the emergence of recent ones increase in the number of Covid infections throughout the world.

WHO naming conventions for brand new COVID variants, letter combos are sometimes used to designate latest variants, particularly those who arise from recombination events between existing lineages. “X” normally means: recombinant variant (equivalent to XBB), while the letters following it discover specific lineages.

So far, we know little about the features of XEC and the way it differs from other variants. However, there is no evidence to suggest that symptoms might be more severe than with earlier versions of the virus.

We only know what mutations this variant has. In the S gene encoding the spike protein, we find the T22N mutation (inherited from KS.1.1), in addition to Q493E (from KP.3.3) and others mutations
known to omicron pedigree.

Will vaccines still work well against XEC?

Latest monitoring data doesn’t show a big increase in the number of hospitalizations because of Covid-19. This suggests that current vaccines still provide effective protection against the severe effects of circulating variants.

As the virus continues to mutate, vaccine firms will proceed to accomplish that proceed to update your vaccines. Both Pfizer and Moderna have updated vaccines targeting the JN.1 variant, which is the parent strain of the FLiRT variants and due to this fact should protect against XEC.

However, Australia is I’m still waiting to seek out out which vaccines could also be made available to the public and when.

In the meantime, omicron-based vaccines equivalent to the current XBB.1.5 spikevax (Moderna) or COMIRNATY (Pfizer) vaccines are still more likely to provide good protection against XEC.

It’s hard to predict how XEC will behave in Australia once summer arrives. We will need more research to higher understand this variant because it spreads. However, provided that XEC was first detected in Europe during the northern hemisphere summer months, this suggests that XEC could also be well-suited to spread in warmer weather.

You don’t have to add sugar to your cranberry sauce this holiday season – a food scientist explains how to cook with less sweeteners

Published

on

By

Holidays are stuffed with tasty and filling dishes and drinks. It’s hard to resist dreams of cookies, special cakes, wealthy meats and exceptionally spicy additions.

Many of the healthy ingredients utilized in holiday dishes could be overshadowed by sugar and starch. While adding extra sugar could also be tasty, it isn’t necessarily good for your metabolism. Understanding the food and cuisine science behind what you cook means you may make a few changes to a recipe and still have a delicious dish that won’t loaded with sugar.

Especially for those who’re someone with type 1 diabetes, the vacations can come with an additional layer of stress and soaring blood glucose levels. However, this just isn’t the time to despair – it’s the vacations in spite of everything.

Cranberries are a seasonal, tasty fruit that could be tweaked in recipes to make them more Type 1 diabetic-friendly – or friendly to anyone searching for a sweet dish without the added sugar.

I’m a food scientist and sort 1 diabetes. Understanding food composition, ingredient interactions, and metabolism literally saved my life.

Type 1 diabetes has been defined

Type 1 diabetes it lasts all day, without sleep breaks, without holidays and weekends, without remission and without cure. Type 1 diabetes don’t produce insulin, a hormone essential for all times, which promote the absorption of glucose, i.e. sugar, into cells. Glucose in your cells then provides the body with energy on the molecular level.

Therefore, people with type 1 diabetes take insulin injections using an insulin pump attached to their bodies and hopefully it really works well enough to stabilize our blood sugar levels and metabolism, minimize health complications over time, and keep us alive.

Type 1 diabetics have in mind mainly type and amount of carbohydrates in food when determining how much insulin to take, but in addition they need to understand the interactions of proteins and fats in food to use it, or bolusappropriately.

Apart from insulin, type 1 diabetics don’t produce one other hormone, amylin, which slows down gastric motility. This means food moves faster through our digestive tract and we regularly feel very hungry. Foods high in fat, protein and fiber can keep you from feeling hungry for a while.

Cranberries, a seasonal snack

Cranberries are native to North America and grow well within the northeastern and midwestern states, where they’re in season from late September through December. They dominate holiday tables everywhere in the country.

Cranberries are a classic Thanksgiving side dish, but cranberry sauce tends to be high in sugar.

One cup of whole, raw cranberries comprises 190 calories. They are composed of 87% water, trace amounts of protein and fat, 12 grams of carbohydrates and just over 4 grams of soluble fiber. Soluble fiber combines well with water, which is sweet for digestive health and might slow the rise in blood glucose levels.

Cranberries are tall IN potassiumwhich helps maintain electrolyte balance and cell signaling, in addition to other essential nutrients similar to antioxidants, beta-carotene AND vitamin C. They also contain vitamin Kwhich helps in healthy blood clotting.

The taste and aroma of cranberries comes from compounds present in fruits similar to cinnamates, which add a hint of cinnamon, vanillin for a vanilla note, benzoates AND Benzaldehydethat tastes like almonds.

Cranberries are high in pectin, a soluble starch that forms a gel and is used as a binding agent in making jams and jellies, in order that they thicken easily with minimal cooking. Their beautiful jewel tone red color belongs to a class of compounds called anthocyanins and proanthocyanidins with which they’re associated treating certain forms of infections.

They also contain phenols, that are protective compounds produced by the plant. These compounds, which appear like rings on the molecular level, interact with proteins within the saliva, causing a dry and tight feeling that causes the mouth to pucker. Similarly, the so-called benzoic acid naturally occurring in cranberries, it adds sourness to the fruit.

These chemical components make them extremely sour and bitter and difficult to eat raw. To moderate these flavors and effects, most cranberry recipes call for plenty of sugar.

All this extra sugar could make cranberry dishes difficult for type 1 diabetics to devour since the sugars cause blood glucose levels to rise quickly.

Cranberries without sugar?

Type 1 diabetics – or anyone looking to limit their sugar intake – can try some cooking tactics to reduce their sugar intake while still having fun with this holiday treat.

Don’t cook the cranberries too long once they pop. You’ll still have a sticky cranberry liquid without having to add a lot of sugar, because cooking concentrates a number of the bitter compounds, making them more visible within the dish.

The addition of cinnamon, cloves, cardamom, nutmeg and other warming spices gives the dish a depth of flavor. Adding heat with hot chili pepper it might make a cranberry dish more complex while reducing sourness and astringency. Adding salt can reduce the bitterness of cranberries, so you will not need a lot of sugar.

For a richer flavor and glossy quality, add butter. The butter also moisturizes the lips, which reinforces the natural tartness of the dish. Other fats, similar to cream or coconut oil, also work.

Adding chopped walnuts, almonds or hazelnuts may decelerate the absorption of glucose, so your blood glucose levels may not rise as quickly. Some recent forms of sweeteners, similar to allulosethey taste sweet but don’t raise blood sugar levels and require minimal or no insulin. Allulose has GRAS – Generally Regarded as Safe – status within the US but just isn’t approved as an additive in Europe.

During the holiday season, you may easily reduce the quantity of sugar added to cranberry dishes and revel in the health advantages without spikes in blood glucose levels.

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.

Bystanders are less likely to intervene if a girl needs cardiopulmonary resuscitation compared to a person.

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.
