Modified mosquitoes to be released to fight dengue

Published

on

WHAT’S BEING CLAIMED:

  • The Florida Keys Mosquito Control District approved a plan to release genetically modified male mosquitoes, on a quest to mate the female Aedes aegypti mosquitoes that would result in killing its offspring to break their population.
  • The plan was commissioned to address the rising cases of Dengue fever and the Zika virus in Florida.
  • Some experts expressed their hesitations on the project as it can negatively impact the ecological system.

An effort to mitigate the spread of insect-borne diseases is being commissioned and will be launched in Florida next year. Genetically modified mosquitoes will be released to prevent illnesses such as Dengue fever and the Zika virus.

This week, the Florida Keys Mosquito Control District approved the plan that will spearhead a 2021 project to counter the striped-legged Aedes aegypti mosquito, the insect that carries the diseases. So far, the Keys island chain recorded about 50 cases of Dengue this year.

The Oxitec biotechnology company plans to release millions of male, genetically-modified mosquitoes to mate with female mosquitoes that suck blood on humans. The male mosquitoes, which don’t bite, would contain a genetically-altered protein that would kill any potential offspring. It aims to decrease the mosquitoes’ population, thereby reducing its chance of transmitting the illness.

In a phone interview on Thursday, Oxitec scientist Kevin Gorman said that the company has successfully launched the same projects in Brazil and the Cayman Islands.

“It’s gone extremely well. We have released over a billion of our mosquitoes over the years. There is no potential for risk to the environment or humans,” he said.

Backing the safety of the project, the company cited previous studies by government agencies like the Environmental Protection Agency and the US Centers for Disease Control and Prevention. 

However, there were some concerns about the use of genetically-modified organisms (GMOs), suggesting it could yield repercussions on the world’s natural balance. Some people questioned the project during a meeting on Tuesday at the Florida Keys mosquito control board.

“You have no idea what that will do,” Florida Keys Environmental Coalition Director Barry Wray said.

Others were questioning if the modified mosquitoes could effectively curb the existence of mosquitoes in Florida.

“The mosquitoes created in a lab have not gone through a natural selection process, in which only the fittest survive and mate. Once they are released in the natural environment, will they be as fit as the naturally occurring males and able to outcompete them for mates?” said Max Moreno, an expert in mosquito-borne diseases at Indiana University. 

Another issue would be on latent environmental consequences, like the effect if another animal (e.g. frog or bird) would eat the modified mosquito.

“An ecosystem is so complicated and involves so many species, it would be almost impossible to test them all in advance in a lab,” Moreno argued. He was neither part of the pilot project nor the company.

Despite the reservations of some, the project will still proceed after board members voted 4-1 in favor of the project. Government agencies in Florida also gave their go signal.

    I believe we did something like this way back in the 1950’s to fight screw worm blow flies that were killing animals.
    Don’t remember any negative environmental disasters.

    Modified ??? Your messing with nature. You know it will come back to bite you on the azz. Now we wait and see how this will affect us and our life’s. Nature doesn’t like being messed with and has a way of working its own magic to fix things. Still don’t know what this Modified means, but betting its not in a good way. We will see tho. And what causes of death it brings.

      The article states that the males are modified so that when they mate the offspring die due to a modified protein that is passed to the female during mating.

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.
