Venom of Deadly Spider Could Prevent Fatal Heart Attack [Video]

Published

on

WHAT’S BEING CLAIMED:

  • The venom of a deadly spider has been found to contain a protein that can prevent fatal heart attacks.
  • The protein could block death signals from the heart.
  • It can also prolong the survival of cells of donor hearts. 

Australian researchers discovered that the venom of the world’s deadliest spiders could save people from dying from heart attacks.

A protein in the venom of the Fraser Island (K’gari) funnel-web spider could potentially prevent the fatal effects of a heart attack, as well as improve the survival rate of heart transplant recipients.

The Australian researchers were from the University of Queensland and were led by Professor Peter Macdonald from the Victor Chang Cardiac Research Institute. Macdonald said they’ve been working on the study for decades. 

Dr. Palpant from UQ’s Institute for Molecular Bioscience (IMB) explained that the potential drug can stop the ‘death signal sent by the heart when a person is having an attack.

“After a heart attack, blood flow to the heart is reduced, resulting in a lack of oxygen to the heart muscle. The lack of oxygen causes the cell environment to become acidic, which combine to send a message for heart cells to die,” said Palpant. 

He added that for the longest time, no drug could stop the death signal in heart cells.

The protein called Hi1a was tested using beating human heart cells that were exposed to stresses that could cause a heart attack.

“The Hi1a protein from spider venom blocks acid-sensing ion channels in the heart, so the death message is blocked, cell death is reduced, and we see improved heart cell survival,” explained Palpant. 

According to Macdonald, heart cells must survive especially during heart transplants, and using the Hi1a can reduce cell death, improving how far the heart can be transported, as well as the success rate of the transplant.

Macdonald said the donor heart can’t be used if it has stopped beating for more than 30 minutes before retrieval. This makes the protein life-changing especially for people who are close to dying.

The HI1a has also been found to improve recovery from stroke by reducing brain damage even when the protein is taken up to eight hours after the stroke started, according to UQ Professor Glenn King. He said the protein could be especially essential when administered by first responders, and in areas that are far from hospitals.

This could also expand the network of available donors and recipients because the donor heart can be transported over longer distances. 

According to Dr. Sarah Scheuer, they initially studied the effect of the venom but took on a whole new path when they found that can prevent some of the injuries that usually occurred during heart attacks when they successfully blocked the channels. 

The researchers are aiming for human clinical trials of the protein within two to three years.

An “Accidental Miracle”: Blind Woman Regains Sight After Placebo Treatment

Published

on

In a Nutshell:

  • Lynley Hood, an 80-year-old author from New Zealand, accidentally regained her vision, lost to glaucoma 12 years ago, during a placebo treatment for her chronic back pain.
  • Participating in a University of Otago study, Lynley was part of the placebo group receiving superficial scalp electrical stimulation. Remarkably, after four weeks, her vision restored almost to full capacity, a result that left her ophthalmologist stunned.
  • Intrigued by this unforeseen recovery, the study team, led by Dr. Divya Adhia, plans to conduct further research into how scalp electrical stimulation might aid in restoring eyesight, potentially leading to a revolutionary breakthrough in treating blindness.

In a surprising twist of medical events, a placebo treatment designed to alleviate chronic back pain inadvertently restored the vision of an 80-year-old blind woman.

Lynley Hood, from Dunedin, New Zealand, an award-winning writer, had lost her eyesight over a decade ago to a rare form of glaucoma and found the world in color once again thanks to a back pain treatment study at the University of Otago.

Hood’s journey into darkness started 12 years ago when her left eye suddenly became blurry while reading a book.

Assuming it was due to fatigue, she retired for the night, only to wake up to a world that hadn’t regained its clarity.

She was soon diagnosed with a rare form of glaucoma and informed by her doctors that there would likely be no improvement in her condition.

Hood eventually became legally blind, which put a pause on her passion for reading and writing.

But life had an unexpected plot twist in store for Hood.

A painful fall in 2020 fractured her pelvis, leading to severe back pain, which strangely, became the pathway to her unexpected vision recovery.

This incident led her to participate in a chronic pain treatment research project conducted by the University of Otago.

The project, split into two groups, involved participants undergoing electrical stimulation sessions while wearing specially wired helmets.

One group received electrical stimulation directly to the brain, while the placebo group, including Hood, received superficial scalp-level stimulation.

Unbeknownst to her, Hood was in the placebo group.

After just four weeks of electrical stimulation, Hood discovered her vision had returned to nearly 100%.

The dramatic improvement left even her ophthalmologist astounded, who couldn’t resist but call it a “miracle.”

“Miracle is not a word we use very often in science, but it was — an accidental miracle,” project co-leader Dr. Divya Adhia told the Otago Daily Times.

“It wasn’t the intended outcome, but to see that my research has actually made an impact on people is incredible.”

Having lived with severely impaired vision for over a decade, Hood is now readjusting to a life that’s in clear sight.

With her vision restored, she is eager to return to her love for writing.

“At first, I thought I was imagining it,” Hood said, expressing disbelief at the return of her sight.

She detailed how the electrical currents, traced by advanced equipment, stimulated her retina, sparking an array of signals down her optic nerve and restoring her vision.

The intriguing question of how the electrical stimulation managed to bring Hood’s eyesight back remains unsolved, but Dr. Adhia and her team are eager to find out.

They’re now planning another study to understand this unexpected visual resurgence better, potentially opening a new window of hope for others living with blindness.

Doctor Fired After Prescribing Ice Cream and Video Games to Sick Child

Published

on

In a Nutshell:

  • A Brazilian doctor was dismissed from his job after prescribing chocolate ice cream and video game sessions to a 9-year-old boy presenting flu-like symptoms, causing a stir on social media.
  • The boy’s mother was initially taken aback by the unusual approach, which saw the doctor not conducting a proper physical examination before prescribing a mixture of drugs, ice cream, and gaming.
  • While some social media users criticized the doctor’s unprofessionalism, others saw it as a humanizing approach. The controversy led to his dismissal from the public health network and sparked discussions about improving medical care in the city.

When the world feels like a never-ending episode of “House,” sometimes the antidote to a stressful day is a big bowl of chocolate ice cream and a spirited session of gaming.

Well, one Brazilian doctor took this idea quite literally and ended up losing his job over it.

This unlikely tale begins in Greater São Paulo when Priscila da Silva Ramos, a doting mother, brought her 9-year-old son to a state-owned clinic.

The child was under the weather, battling a sore throat and flu-like symptoms.

However, what unfolded was a curious mix of video games, chocolate ice cream, and a baffled mother.

Dr. [Unnamed], as we’ll call him, decided to forego the traditional diagnostic process.

He didn’t examine the young patient, choosing instead to prescribe a cocktail of drugs along with daily servings of chocolate ice cream and rounds of the mobile video game, Free Fire.

“He started writing the prescription without examining my son, without looking at his throat, without examining his chest, without anything,” Ramos revealed.

When he inquired about the boy’s preference for ice cream flavors, Ramos never thought he’d take it to heart.

Yet, right there on the prescription, next to amoxicillin and prednisolone, were the words “chocolate ice cream” and “Free Fire.”

The absurd prescription wasn’t noticed until the following day when the boy’s aunt spotted the unusual advice.

Swiftly, the strange prescription made its debut on Facebook, becoming an overnight viral sensation.

The doctor’s peculiar brand of ‘medical advice’ ignited mixed reactions on social media.

Some considered it a case of unprofessional conduct, while others found it to be a humorous humanizing approach towards the child.

Henderson Furst, the president of the Bioethics Commission of the Brazilian Bar Association, São Paulo, supported the latter viewpoint.

He said, “Some doctors who have a practice of humanizing the relationship by making prescriptions that contain some things out of the ordinary, but which represent an act of humanization in that relationship.”

Nevertheless, the “ice cream doc,” didn’t get a free pass on this one.

As the controversy swirled, he found himself dismissed from the Brazilian public health network, as announced by the City Hall of Osasco.

Ramos, the boy’s mother, hopes this incident will spur improvements in medical care in the city.

As for the little boy, well, we reckon he might have been a tad disappointed by the doctor’s dismissal – after all, who wouldn’t want a doctor who prescribes gaming and ice cream?

Canadian Woman Pretty Sure She’s Allergic to Running [Video]

Published

on

In a Nutshell:

  • Divz Mangat, a 27-year-old woman from Canada, believes she might have a rare disorder, exercise-induced anaphylaxis (EIA), which causes her to break out in hives and struggle with breathing whenever she runs.
  • This potential diagnosis came after several incidents, including one during a flight to the Dominican Republic, where running to catch her plane resulted in a severe allergic reaction.
  • The video of her experience posted on TikTok drew attention from many viewers who shared their experiences with similar symptoms, some suggesting she might indeed have EIA.

A Canadian woman, Divz Mangat, suspects that she might be allergic to running. For several years, she has been experiencing hives and breathing difficulty following physical activity, specifically running.

“For the past few months, every time I run or get stressed out, I’ve been breaking out in hives. I wasn’t sure if it was due to running or stress. But, that day, I realized it 100 percent has to be due to me running and being stressed out,” Divz told Newsweek.

Divz’s suspicions were further substantiated during a recent flight to Punta Cana in the Dominican Republic.

When running to catch her flight, she had a severe allergic reaction.

Her sister, Dee Mangat, documented the entire episode in a video that has since gone viral on TikTok, amassing over 6.6 million views.

At least we figured out whats she’s allergic to finally! Know anyone else that has the same allergy? 🏃‍♂️ #dayinmylife #allergy #vlog #dee_m6 ♬ original sound – Dee | Real Estate and Life

While waiting for an appointment with a specialist, Divz has hypothesized that she might be suffering from exercise-induced anaphylaxis (EIA).

EIA is a rare condition that prompts symptoms such as widespread skin flushing, hives, skin and lip swelling, and nausea and vomiting after physical activity.

In severe instances, sufferers can experience anaphylactic shock, leading to a dramatic drop in blood pressure, potential collapse, and difficulties in breathing and swallowing.

Her sister, Dee, expressed her initial disbelief.

“‘I think I might be allergic to running,’ she said. I was like, ‘Yeah, OK, sure. I’ve never heard of that.’”

However, when Divz administered her EpiPen medication and the hives subsided, it became clear that an allergic reaction had indeed occurred.

Now with an understanding of her potential trigger, Divz is being more cautious.

“The whole trip the girls were like, ‘Don’t run. Just walk where you have to go,’” she said.

“I’m very cautious of not making my heart beat really fast. I’m just trying to be very calm and make sure it doesn’t happen again.”

Divz’s video drew a myriad of responses from viewers who shared their experiences and insights, with many asserting the reality of exercise-induced anaphylaxis and encouraging her to get tested.

Divz expressed her appreciation for the responses, “It’s kind of nice because people have been telling me what’s wrong with me.

“Doctors have reached out and let me know there are lots of possibilities, and when you read the comments, some people say it took them years to figure out.”

While she still awaits a professional diagnosis, Divz is grateful for the awareness her video has raised and the support she has received.

“Seeing other people having similar things it does help, in a way,” she concluded.
