How magic shrooms affect your brain

Following is a transcript of the video.

Narrator: This is the map of a typical human brain, and this is the map of a brain on psilocybin, the psychoactive compound in magic mushrooms. All those new connections you can see don’t just make people trip. They’re also the reason that psilocybin is one of today’s most talked-about drugs in certain medical circles. Worldwide, more than 180 species of mushrooms produce psilocybin, likely as a defense strategy. Scientists believe that psilocybin may dampen the appetite of predatory insects like ants so that they feel full long before eating their way through the entire mushroom. Humans, on the other hand, well, they trip.

Johnson: Psilocybin is a so-called classic psychedelic, so it’s in the same category as drugs like LSD and works in the brain in basically the same way.

Narrator: When you take psilocybin, your gut converts it into another chemical, known as psilocin, which binds to serotonin receptors called 2A, and experts think that’s what triggers what they call neuronal avalanching. It’s essentially a domino effect of different changes in the brain. You’ve got increased activity in the visual cortex, which leads to changes in your perception, and then decreased network activity in the default mode network, which leads to a loss of ego.

Johnson: And that may be why people often report at high doses a profound sense of unity, transcending beyond themselves.

Narrator: But perhaps most importantly, psilocybin increases connectivity among different regions of the brain.

Johnson: Because of that receptor activation, there is a profound change in the way that different areas of the brain synchronize with each other.

Narrator: Think of it like an orchestra. Normally, the brain has different musical groups that each play independently.

Johnson: A sextet there, here’s a quartet there. This one’s playing jazz. This one’s classical, and a number of other ones.

Narrator: But once psilocybin enters, it’s like you suddenly have a conductor.

Johnson: So there is this communication between areas that are normally kind of compartmentalized and doing their own thing.

Narrator: Scientists believe that it’s a combination of these effects that make psilocybin so useful for combating depression and addiction. When new areas in the brain start talking to each other, for example, you might have new insights into old problems. And that’s why some experts describe tripping as a condensed version of talk therapy. And then dissolving your ego, Johnson says…

Johnson: Can be profoundly healing.

Narrator: And there’s actually an increasing amount of research to prove it. In two studies published in 2016, researchers gave cancer patients with depression a large dose of psilocybin, and even six months later, at least 80% of them showed significant decreases in depressed mood. And research on addiction is equally promising. In a study led by Johnson, 15 volunteers took psilocybin to quit smoking, and after six months, 80% of them had kicked the habit, compared to a rate of about 35% for the drug varenicline, which is widely considered the best smoking-cessation drug out there. Yet despite these results, psilocybin is still listed as a Schedule I drug, a category reserved for compounds that have no currently accepted medical use and a high potential for abuse. Now, taking magic mushrooms recreationally does come with some risks.

Johnson: So a dramatic example would be driving under the influence of psilocybin or using it in a way that interferes with your job, or your family relations, or your schoolwork, for example.

Narrator: But as far as scientists know, long-term use doesn’t damage the brain in the way that other drugs can, and according to at least one study, it’s actually the safest drug out there. In 2018, for example, just 0.3% of people who reported taking them needed medical emergency treatment, compared to 0.9% for ecstasy and 1.3% for alcohol. Taken altogether, that’s why some states across the country have campaigned to decriminalize psilocybin, including Denver, which, in May of 2019, became the first ever to succeed.

  • Shares in Rite Aid fell 22% at the market open on Thursday after the company cut its full-year forecast.
  • A decline in cases related to cough, cold, and flu hurt the drugstore chain’s fourth-quarter sales.
  • Social distancing measures and a long winter impacted its fourth-quarter sales, the chain said.

Rite Aid fell by as much as 22% on Thursday after the company said its full-year results would be undermined by declining numbers of people falling sick with colds and coughs.

The retail drugstore industry has been hit by a weak sales season, due to measures to curtail the spread of coronavirus, the company said. As a result of physical distancing, face masks, and use of sanitizers, Rite Aid said it saw a decline of nearly 37% in its cough, cold, and flu-related product categories.

Rite Aid revised its expected full-year earnings before interest, taxes and depreciation to between $425 million and $435 million, from a prior forecast of between $490 and $520 million.

“During the fourth quarter, our industry was impacted by a historically soft cough, cold and flu season, as well as the continued impacts of COVID on the deferral of elective procedures and related acute prescription volume and selling, general and administrative expenses,” president and CEO Heyward Donigan said in a statement.

Front-end same store sales, a key metric that determines how well existing locations are performing, fell 5.6% for the company’s fourth quarter that ended on February 27. The winter season also contributed to a slump in its supply chain and a drop in sales, Rite Aid said.

Rite Aid shares closed at $23.34 per share on Wednesday, but sank 22% to $18.28 per share at Thursday’s market open.

How anesthesia affects your brain and body

Since 1846, doctors have used a variety of drugs to make patients unconscious for surgery, but even though the medications have changed, there’s one thing that remains the same- it works. But how exactly? We don’t know every detail about what’s going on when we administer anesthesia, but then again, we also don’t know exactly how consciousness works either. Following is a transcript of the video.

Narrator: When you go to sleep, if I pinched you, you’d be up. If I shook you, you’d be up, right? But under anesthesia, I’m gonna pinch you and do a full operation and you’re not up. So it’s really further on the spectrum of unconsciousness.

Narrator: When you wake up after being put under with general anesthesia you barely feel like any time has passed. You could have been out for an hour or a day and you wouldn’t know the difference.

Fong: When you go to a natural sleep, people call your name, your alarm goes off, you wake up, right? This is not what is gonna happen during general anesthesia. You’re gonna be unconscious.

Narrator: You’re closer to being in a coma than being asleep.

Anesthesia was first used during surgery in 1846. The drug provided at that time was ether. Now anesthesiologists more commonly use a combination of drugs like propofol and fentanyl which interrupt neural pathways so you don’t feel pain and you don’t remember the surgery.

Fong: Three things that you need for general anesthesia are you need amnesia so that they don’t remember, analgesia so they have pain relief and then operating conditions for the surgeon. Some surgeries you need the patient to be very relaxed so you would use a muscle relaxant. Other surgeries the patient just needs to be asleep and anesthetized but they don’t need relaxation so how they do that varies upon the different medications that you’re using. Some will depress excitatory neurons and some will enhance inhibitory neurons.

Narrator: Excitatory neurons, for example, get excited and send signals to other neurons to fire. Depressing them means less signals telling your brain you’re in pain. Inhibitory neurons do the opposite. They make it harder for neurons to generate these electrical signals. In either case this means fewer active neurons overall which is important because when your body is being poked and prodded, neurons would typically fire to tell your brain you’re in pain. If those neurons aren’t firing, your brain doesn’t know that your body is, well, being cut open.

Fong: Basically it interrupts the pathways and the communication between your neural networks. We’re aiming for them to be not in pain by looking at their vital signs, their heart rate, their blood pressure. Then we want to make sure that they’re unconscious.

Narrator: Without anesthesia, many important surgeries wouldn’t be possible because they’d be way too traumatic.

Fong: Surgery didn’t move forward, really, until anesthesia moved forward. You know, you watch those old movies. They give you a swig of alcohol, they put a tourniquet and they hack your leg off. People don’t do well with that, right? If you had a bad heart, that would be the end of that.

Narrator: After the procedure is complete the doctors stop administering the meds and the most powerful effects of the drugs wear off but even though you’re conscious again you might continue to experience some of the drugs side effects.

Doctors are calling to investigate a prestigious medical journal after it tweeted ‘No physician is racist’

Doctors are calling to investigate one of the country’s most prestigious medical journals.

The Institute for Antiracism in Medicine, an antiracism group founded by three Black women physicians, launched a petition against The Journal of American Medical Association after the publication tweeted “No physician is racist, so how can there be structural racism in health care?”

JAMA, a peer-reviewed medical journal that dates back to 1883, is the most widely circulated journal in the world, per its website. JAMA’s now deleted tweet promoted a podcast episode where two editors discussed how to talk about racism in medicine.

“Structural racism is an unfortunate term,” JAMA deputy editor Ed Livingston said in the podcast, which has also been deleted, according to The Root. “Personally, I think taking racism out of the conversation will help. Many of us are offended by the concept that we are racist.”

JAMA removed the podcast after Black doctors and other medical experts brought attention to offensive remarks about race in the episode. Editor-in-chief Howard Bauchner released a statement apologizing for the harm caused by the tweet and parts of the podcast.

The petition calls the investigate whether Bauchner failed to diversify editorial staff or discriminated against them. The group is also calling on JAMA to hire a deputy editor dedicated to antiracism and health equity publications, and schedule town halls with Black, Indigenous, and other community members of color.

The petition had more than 1,600 signatures as of Tuesday morning.

Research suggests racial bias in medicine leads to worse patient care for Black people. A 2016 report found half of white medical students and residents in the study endorsed false beliefs about biological differences among Black and white people, which led to making less accurate treatment recommendations for Black patients.

Doctors and nurses tend to not take Black patients’ pain as seriously as white patients. A national study of nearly one million emergency room visits found Black children had one-fifth the chance of receiving opioid painkillers compared to white children, The Washington Post reported.

The result of decades of racial bias in medicine has led to Black people having less trust in the life-saving COVID-19 vaccine.

Medical institutions in the US have taken some responsibility for the industry’s racial bias, prompted by the COVID-19 pandemic’s outsized impact on Black people and the calls for accountability during the 2020 George Floyd protests.

The American Medical Association recently defined racism as a public health threat. In 2018, AMA had apologized for actively discriminating against Black doctors and barring them from joining medical societies between the 1800s to the 1960s.

JAMA has been revising its editorial style for reporting on race and ethnicity over the last eight months.

JAMA and the Institute for Antiracism in Medicine were not immediately available for additional comment.
