    Dr. Ajit Nirmal: How and Why Cancers Spread

    Dr. Ajit Nirmal: How and Why Cancers Spread

    When we hear the term tumor or cancer, the image that often comes to mind is a bunch of bad cells next to normal ones, and growing. Like many things, it's just not that simple. How do the normal cells turn bad? Can our immune systems detect the cancer cell and kill it? Why does some, initially successful, chemotherapy stopped working? Why does cancer spread? These are all great questions, since cancers of one kind or another, will affect so many of us either as patients, friends, or loved ones. Well, basic science is providing some critical answers. In today’s episode, Therese Markow and Dr. Ajit Nirmal discuss just these questions. 
     
     Key Takeaways:
    If we didn't have an immune system, we'd all get cancer.  Drug resistance continues to be the principal limiting factor to achieving cures in patients with cancer. Once a normal cell has turned cancerous, it is likely dividing much faster than a normal cell. This rapid cell division is error prone, and can lead to accumulation of mutations at a much faster rate.  
    "I truly believe, with adequate basic understanding of the molecular underpinnings of cancer evolution, and how the tumor microenvironment helps it or promotes it, we will be able to predict the best course of action to target all cancer cells up until the very last one, and consequently to the patient." —  Dr. Ajit Nirmal

    Fluoride: Your Teeth and Your Brain

    Fluoride: Your Teeth and Your Brain

    Evidence is emerging that fluoride, a chemical that helps prevent dental cavities or caries, also is a neurotoxin that can cross the placenta and enter the developing brain. Recent studies reveal that excess fluoride during fetal development can result in impaired intelligence and cognition in children.
     
     Key Takeaways:
    Fluoride helps prevent tooth decay. An excess during gestation can produce dental "fluorosis" , discolored and even pitted teeth in the children Fluoride is also a neurotoxin, detectable in the parts of the brain involved in learning and memory Recent studies show an association between fluoride in maternal urine during pregnancy and impaired behavior in children People are getting more fluoride now because it is used in beverages, personal care products, and polluted air.  
    "Strong associations exist between the level of maternal urinary fluoride, in other words, how much the mother was exposed to, and the test scores of their children." —  Therese Markow, Ph.D.

    Your Brain: How It Remembers

    Your Brain: How It Remembers

    What happens when we remember something?  Therese Markow talks with neuroscientist Dr. Ben Albensi about how memory works, involving both chemical and structural changes.  They talk about the signals in the brain, the connections among different brain regions underlying memory, and the role of sleep in consolidating the memory process.  Dr. Albensi also describes what happens when a person suffers amnesia.
     
     Key Takeaways:
    Memory begins in the brain region called the hippocampus, from which chemical signals and neural connections then extend to other regions. These connections are important for memory. Enriched environments result in more connections. Sleep is critical to the memory process.  
    "We’ve learned from scientific evidence and experiments that sleep is critical to quality of memory and memory consolidation." —  Dr. Ben Albensi

    Males at Risk: Sperm Declining

    Males at Risk: Sperm Declining

    Infertility is on the rise, leading otherwise healthy young couples to seek a form of assisted reproductive technology appropriate for their particular situation. This increase infertility of considerable concern. Is one sex affected more than the other? What are the long-range implications if the trend keeps going? Is it only humans that appear to be affected? And the critical question is why? In today’s episode, Therese Markow and Dr. Shanna Swan, author of the new book Count Down, answer many of these questions, including discussion of the types of chemicals and other factors that may contribute to the rising infertility.
     
     Key Takeaways:
    The number of “good” sperm observed in human populations (as indicated by the WHO) has dramatically decreased. Other characteristics for function, such as abnormal shape, inability to swim correctly, and chromosomal abnormalities are increasing as well. Male and female infertility is about 50/50. Newborn babies are being born “pre-polluted” with up to 100 environmental chemicals.  One solution you can undertake yourself is to determine where your food comes from, as that’s what’s going into your body.  
    "I'm convinced that a large proportion of the decline we're seeing is due to chemical exposures, man-made chemicals." —  Dr. Shanna Swan

    Dr. Amanda Giordano: Behavioral Addictions

    Dr. Amanda Giordano: Behavioral Addictions

    Many people have addictions. While much of the time we think of substance addictions, such as drugs or alcohol, there is an increasing rise in behavioral addictions as well, which are often not viewed in society as addictions however real they are and however many issues they cause. Where are these addictions coming from? How do they form? How can they be treated?  In this episode, Therese Markow and Dr. Amanda Giordano, author of A Clinical Guide to Treating Behavioral Addictions, discuss just these questions and go into further details regarding the topics, including cyber sex addiction, genetic predispositions to addiction, and how the itnernet has affected the rise of behavioral addictions. 


     
     Key Takeaways:
    Our brains pay attention to what causes a release of dopamine and pay more attention to those behaviors, increasing the desire and motivation to seek out those rewards associated with that release.  There is a difference between high involvement in a behavior and addiction in a behavior. If it doesn’t hit the 4 C’s of addiction (compulsion, loss of control, negative consequences, cravings) it may not be an addiction.  There are resources available for behavioral addictions, like there are for substance addictions.  We're seeing that online relationships don't take the place of the offline connection and that need to belong.  
     
    "For the longest time, addiction was seen as a moral failing or the result of a character flaw. Unfortunately, that view is still very present today. But we know that it's not a morality issue - it's a biological, psychological and social issue." —  Dr. Amanda Giordano

    Science and Sexual Assault

    Science and Sexual Assault

    Sexual assaults of women, men, and children are always in the news. We know a lot about this when it comes to little children, but for adults, especially women, what constitutes a sexual assault? Lack of consent, forced intimate relations? How does one prove an assault took place? Often the information provided by medical forensic experts is brought to bear on these cases. Today's guest, Dr. Felice Gersh, is not only a distinguished OBGYN and Integrative Medicine Specialist, but she often serves as an expert witness when medical forensics are required to clarify if or what type of sexual assault took place. This is an important, interesting, and sometimes very fuzzy topic. In today’s episode, Therese Markow and Dr. Gersh discuss this process and the challenges of sexual assault cases.
     
     Key Takeaways:
    When reporting acute sexual assaults, there are special nurses in the hospital called SANE nurses, sexual assault nurse examiners, that will do a detailed forensic examination on the victim. These exams are standardized nationally. In the courtroom, you speak about genitalia as the body parts they are. It makes everyone feel more comfortable when you speak of things anatomically rather than treating them as hush hush.  As a forensic medical expert, it is important to report the facts and what can or cannot be possible, not to decide if someone is innocent or guilty.   
    "My job [as a medical forensic expert] is really an educator. My job is to review the evidence, then explain everything in as clear, plain, and understandable language as I can to a jury so that they will understand what the evidence really means." —  Dr. Felice Gersh

Incredible and informative podcast

Critically Speaking is the perfect balance of scientific concepts in plain English. The topics aired on the show sometimes are very complex issues, but are always told in an enjoyable and easy to digest way. I also love that no two weeks are the same and the topics are always changing - there is truly something for everyone.
