In this episode, Therese Markow and Dr. Peter Liang discuss the rise in colorectal cancer among younger people, those below the age of 50. While colorectal cancer is a slow-growing cancer, it is still the third most common cancer for both men and women, and the second leading cause of cancer death in the United States. Due to the trend of decreasing age in colorectal cancer patients, screening guidelines have been lowered to 45, but can be done earlier as needed, based on risk factors. Dr. Liang emphasizes the importance of screening, diet, exercise, and awareness of family history in preventing and detecting colorectal cancer early.

Key Takeaways:

• Colorectal cancer is the third most common cause of cancer in both men and women. It is the second leading cause of cancer death behind lung cancer.

• Early-onset colorectal cancer is traditionally defined as occurring in people under age 50. However, there is a rise in people in their 40s, though some (though they are a minority) are in their 20s or 30s.

• Colorectal cancer is unique due to the number of different tests available for screening for prevention.

• Colorectal cancer is a slow-growing cancer. A single polyp can sometimes take 10-20 years to develop into cancer.

• There is no evidence correlating constipation with colorectal cancer. If people want to do juices or fasts or colonics, that is fine, but there is no medical need to do it.

• If you have symptoms that are concerning, tell your doctor. Sometimes you do need to advocate for yourself to get additional testing.

"Any test that is not a colonoscopy and is abnormal does need to be followed by a colonoscopy. How we prevent Colorectal cancer is by going in with the colonoscopy, removing polyps (which can turn into cancer), or by finding the cancer early, so that your prognosis is much better." — Dr. Peter Liang

In this episode, Therese Markow and Dr. Joshua Woolley discuss his transition from neurology to psychiatry and his current focus on psychedelic drug therapies. He explains the mechanisms and effects of psychedelics like psilocybin and LSD, highlighting their potential to treat depression and other mental health conditions. Dr. Woolley describes controlled clinical trials at the University of California, San Francisco, where patients undergo psychedelic experiences with therapeutic support. He notes the challenges and benefits of these treatments, including long-term positive effects in alleviating depression. He also addresses the regulatory hurdles and the potential for future FDA approval of psychedelic therapies.

Key Takeaways:

• While SSRIs can and have saved a lot of people, they don’t work fully or at all for some people.

• Some diagnoses don’t have any effective pharmacotherapies, such as anorexia, methamphetamine use disorder, and even PTSD.

• Over the years, a lot of people have said that psychedelics have allowed them to have real, transformative experiences. It is a common description.

• To conduct psychedelic research, you have to get permission from multiple organizations, including the FDA and the DEA.

• People do sometimes have frightening experiences when they take psychedelics. This is not likely to happen in a clinical setting with support.

"Almost every psychiatric illness can be thought of as an inability to change something about emotions, thoughts, or behavior. If psychedelics really do reopen these critical periods, or allow people a period of a window of changeability, that would be a real game changer." — Dr. Joshua Woolley

In this episode, Therese Markow interviews Dr. Shaina Stacy about her studies on cancer risks in children depending upon the body mass index (BMI) of their mothers before and during pregnancy. Dr. Stacy explains how she obtained a sample of nearly 2 million mother-child pairs in the state of Pennsylvania, the largest sample size ever for such a study. They discuss how children of women with a BMI of over 30 when pregnant had a significantly higher risk of cancers compared to children of lean mothers. This was notable for leukemia in children under 5, especially acute lymphoblastic leukemia (ALL). The mechanism underlying the increased risk is not yet known.

Key Takeaways:

• Maternal obesity before and during pregnancy increases the risk of cancers in children under 5 years of age.

• The risk of leukemia, especially acute lymphoblastic leukemia or ALL, is the greatest.

• Children of white, educated women, if obese during pregnancy, have the highest risk.

• Transgenerational effects of obesity are becoming more apparent.

"We found that children born to mothers in our highest BMI category had over 30% higher risk of developing any type of childhood cancer." — Dr. Shaina Stacy

In this episode, Therese Markow and Dr. Cheryl Hawkes discuss the increasing scientific evidence that maternal obesity affects the developing fetal brain. While many of the effects manifest early, in infant temperament and childhood cognitive (IQ) decrements, other effects do not show up until years later, in adult psychiatric and neurodegenerative problems. The physical bases for these changes in fetal brains are also clearly evidenced in laboratory model systems, such as mice, where the maternal diets can be controlled, and the offspring not only can be given behavioral tests, but their brains can be dissected to reveal the changes in the blood vessels caused by obese mothers.

Key Takeaways:

• Children born to obese mothers have lower IQs and poorer motor, spatial, and verbal skills.

• Mice and rodents have similar brain development to humans, which is why rodent study models are so beneficial to science.

• Brain maturation takes many years. Your brain is fully formed at birth, but continues to mature and change into your mid-twenties.

"Because of the rise in obesity globally, a lot of people have started to look, rather than looking at famine…, to now shift our attention to looking at the long-term effects of obesity because 30% of women around the world, over the age of 18, are now considered to be obese." — Dr. Cheryl Hawkes

In this episode, Therese Markow and Dr. Diane Tober discuss the global egg donation industry, highlighting its lack of regulations and exploitative nature. Dr. Tober details some of her research on egg donors, revealing severe risks and some life-threatening complications that can affect 10-12% of donors. They discuss how donors are often uninformed about the risks and the pressures faced by donors to donate beyond current guidelines. With compensation varying wildly, there are often financial pressures that donors face, too. Finally, Dr. Tober advocates for standardized informed consent, actual limits on donation cycles, and a national registry to track donor health.

Key Takeaways:

• Changes to preserving and freezing eggs in 2013 changed from slow freezing to flash freezing, which better preserved the egg and changed the industry.

• Not having limits on the number of children that can be born from donated sperm or eggs can have dire consequences for the people conceived from those donations.

• There are discrepancies in compensation based on education, race, and other traits that are considered to be desirable for intended parents.

• There are no consistent laws or regulations regarding who pays for donor medical complications.

• There is no perfect system currently existing for egg donation. But creating a safer system could begin with a donor registry.

"Sometimes donors exceed the limit because of the financial incentives, and sometimes donors exceed the limit because they're coerced or enticed by the agencies or clinics that are using them and profiting off of them." — Dr. Diane Tober

In this episode, Therese Markow and Kim Mutcherson discuss the legal and ethical implications of the increasing number of frozen embryos and the complications of assisted reproductive technologies. With an estimated over 1 million frozen embryos in the United States, this is a complex topic, particularly around state laws, embryo disposition, the financial costs of IVF, and the potential increased regulation and legal challenges moving forward.

Key Takeaways:

• There is no hard data on how many embryos are currently frozen around the world, but there are estimated to be millions.

• States differ, legally speaking, as to whether an embryo is considered a person. How do we determine what obligations related people have to an embryo?.

• There are many different options for what you can have done with your embryos, and those outcomes should be included in the contract before any medical care is provided. Because laws regarding frozen embryos vary from state to state and this should be considered when people are looking to set up a clinic or go through the process.

"Once you have created a business - an industry - that creates human beings, it is inevitable that you are going to run into all sorts of really difficult issues. You can't get around it. It's just the nature of the thing. And so if we're going to have this industry, and if it's going to exist, we're going to constantly be asking ourselves difficult legal questions, difficult ethical questions, and difficult moral questions." — Kim Mutcherson

The opinions expressed by Dr. Beyrer are his own and not those of his employer.

In this episode, Therese Markow and Dr. Chris Beyrer discuss the importance of USAID, highlighting its role in global health and development, particularly through programs like PEPFAR, which has saved 25 million lives and prevented millions of HIV infections. Dr. Beyrer emphasizes that the economic and security benefits of USAID, whose support amounts to less than 1% of the total US federal budget, have had important benefits at home in the United States. It protects us from infectious diseases like Ebola and MPOX. Cuts to USAID could lead to a resurgence of HIV, polio, malaria, and other diseases. Finally, Dr. Beyrer advocates for listeners to become informed, to understand what is happening, and to engage in their citizenship rights for the benefit of all.

Key Takeaways:

• By law, USAID was only allowed to buy food from US farmers, but stopping USAID has thrown farmers into crisis due to the unstable purchasing now.

• Until January 20, 2025, USAID was supporting about 21 million people worldwide on antiviral therapy. It was also one of the biggest funders and supporters of HIV prevention because treatment is not enough - you must reduce new infections to get out from under the treatment burden.

• The only group right now that we are supporting PrEP for is pregnant or lactating, breastfeeding mothers who are at risk for HIV. Everybody else who is on PrEP has been abruptly halted. 2025 could be the year that we see the beginning of the second wave of the AIDS pandemic.

"These programs really save lives. They have saved millions of lives. We know that; we've documented it carefully. It is so important to be informed, to stay informed, to understand what is happening, and really to engage. Now, more than ever, engage in your citizenship rights." — Dr. Chris Beyrer

In this episode, Therese Markow and Dr. Adam Berinsky discuss political rumors and misinformation. Dr. Berinsky defines rumors as unsubstantiated claims without evidence, emphasizing their social transmission. He identifies two factors influencing rumor belief: conspiratorial thinking and partisan polarization. Berinsky's research reveals that while some people firmly believe rumors, others are ambivalent and more open to correction. He suggests focusing on these undecided individuals rather than entrenched believers. Berinsky also highlights the role of political leaders in spreading misinformation and the need for creative messaging to counteract it.

Key Takeaways:

• Political rumors (or misinformation) are claims that are unsubstantiated by the balance of publicly available information.

• Republicans and Democrats are equally (or very nearly) likely to believe different pieces of misinformation that they're presented with. Currently, Republican politicians are more likely to spread misinformation.

• The more attention you pay to politics, the more likely you are to listen to people on your side.

• Better-educated and more informed people should be more likely to reject misinformation, but what we find is that actually, they're more attuned to the partisan angle of that information.

"Maybe our effort is better spent on trying to get these people who are not sure where they stand, because those are the people that we can move." — Dr. Adam Berinsky
