The Importance of Hope

Posted by in categories: biological, education, health, homo sapiens, life extension

hope

I learn useful life lessons from each patient I meet. Some are positive messages, reminding me of the importance of maintaining balance between family, work, and leisure activities, but more frequently I witness examples of the remarkable resilience of the human spirit when facing the reality and risks of a major surgical procedure and a diagnosis of cancer. Rarely, patients and their family members utter remorseful or simply sad remarks when they are faced with a grim prognosis and the emotions associated with an onrushing date with mortality. These comments invariably involve an inventory of regrets in life, including, “I should have spent more time with my kids,” “I wish I had told my father (or mother, brother, sister, child, or some other person) that I loved them before they died,” and “I have spent my entire life working, I never took time for anything else.” I wince when I hear these openly expressed remonstrations, I recognize that I am hearing painful and heartfelt truths. Not a week goes by that I am not reminded that I do not one day want to look back at my life with a long list of regrets, should have dones, and what ifs.

I was blessed to meet a great teacher in the guise of a patient early in my academic career. He came to my clinic in my first year after completing a Fellowship in Surgical Oncology, my first year as an Assistant Professor of Surgery. My patient was a 69 year-old Baptist Minister from a small town in Mississippi. He was referred to me by his medical oncologist who called me and said, “I don’t think there is anything you can do for him, but he needs to hear that from you because he doesn’t believe me.” This tall, imposing man had colon cancer that had metastasized (spread) to his liver. The malignant tumor in his colon was removed the year before I met him, and he had received chemotherapy to treat several large tumors found in his liver. The chemotherapy had not worked and the tumors grew. At the point I met him, the medical oncologist told him he would live no more than 6 months, and because he was an avid fisherman when not preaching or helping others in his community , the doctor suggested that he go out and enjoy his remaining time by getting in as much fishing as possible. I learned two invaluable lessons from this patient and his family. First, never deny or dismiss hope from a patient or their family, even when from a medical perspective the situation seems hopeless and the patient is incurable. Second, quoting the minister directly, “Some doctors think of themselves as gods with a small ‘g’, but not one of you is God”.

When I first walked into the examining room, this man was slouched on the examining table in the perfunctory blue and white, open-backed, always unflattering hospital gown. He made eye contact with me briefly, then looked down to the floor. In that momentary meeting of our eyes, I saw no sparkle, no life, no hope in his eyes. He responded to my initial questions with a monotonic and quiet voice. Several times I had to ask him to repeat an answer because his response was so muted. Mid-way through our first visit, the patient’s wife told me he had been very depressed by his diagnosis of untreatable metastatic colon cancer. She reported, despite his occasional side-long warning glances requesting her silence, that while he was eating well, he was spending most of his time sitting in a chair or laying in bed, and that the active, gregarious man with the quick wit and booming voice she had married was gone.

3D-Printed Drugs Coming Soon

Posted by in categories: 3D printing, biotech/medical, health

Frankly, in the US this makes me really nervous. Placing drug making 3D printers in your local pharmacies. I hope that the manufacturer has a mechanism setup to cause the machine not to work if it is stolen by the local drug gangs.


The brave new world of 3D-printed drugs in the healthcare industry is heating up.

Never Say Die – SELF/LESS from Science-Fiction to –Fact

Posted by in categories: biotech/medical, cyborgs, ethics, health, life extension, neuroscience, robotics/AI, transhumanism

In SELF/LESS, a dying old man (Academy Award winner Ben Kingsley) transfers his consciousness to the body of a healthy young man (Ryan Reynolds). If you’re into immortality, that’s pretty good product packaging, no?

But this thought-provoking psychological thriller also raises fundamental and felicitous ethical questions about extending life beyond its natural boundaries. Postulating the moral and ethical issues that surround mortality have long been defining characteristics of many notable stories within the sci-fi genre. In fact, the Mary Shelley’s age-old novel, Frankenstein, while having little to no direct plot overlaps [with SELF/LESS], it is considered by many to be among the first examples of the science fiction genre.

Round Up linked to cancer

Posted by in categories: biotech/medical, food, health, sustainability

Bad news if you use RoundUp.


Local councils across Australia that use the weed killer glyphosate on nature-strips and playgrounds are being warned that the chemical probably causes cancer.

An updated World Health Organisation (WHO) warning for the herbicide, often trade marked as Roundup, is also routinely used in household gardens and farms.

Nanopatch polio vaccine success

Posted by in categories: bioengineering, biotech/medical, health, nanotechnology

Needle-free Nanopatch technology developed at The University of Queensland has been used to successfully deliver an inactivated poliovirus vaccine.

Delivery of a polio vaccine with the Nanopatch was demonstrated by UQ’s Professor Mark Kendall and his research team at UQ’s Australian Institute for Bioengineering and Nanotechnology, in collaboration with the World Health Organisation, the US Centres for Disease Control and Prevention, and vaccine technology company Vaxxas.

Professor Kendall said the Nanopatch had been used to administer an inactivated Type 2 poliovirus vaccine in a rat model.

Human Babies from CRISPR Pigs

Posted by in categories: bioengineering, biotech/medical, genetics, health

New genetic technologies like CRISPR/Cas9 gene editing and synthetic biology are leading us to entirely new definitions of disease. Now “patients” include people who want children who lack some of their own genes, or have additional ones that they themselves lack. Also among the new patients are people who in the past were too old to have children as well some women who get sick from pregnancy and childbirth, or even the idea of them. Technological advances on the horizon may eventually offer treatment for such conditions.

In February 2015 the British Parliament approved production of “three-parent” children by transferring the nucleus of one woman’s egg into the nucleus-less (“enucleated”) egg of a second woman to avoid the propagation of certain rare “mitochondrial” diseases, Though there were acknowledged risks of the unprecedented procedure (including the possibility of producing novel birth defects), the argument that prevailed was that some mitochondrial diseases are so devastating that it should be tried in the narrowly defined group of prospective mothers carrying defective mitochondria.

Not long afterward, news articles began to appear discussing use of the technique for an entirely different purpose. The procedure’s inventor, the Oregon Health & Science University biologist Dr. Shoukhrat Mitalipov, was now proposing to treat infertility in older women by transferring their egg nuclei into the enucleated eggs of younger women.

Military Cyborgs May Soon Be a Reality

Posted by in categories: biotech/medical, cyborgs, drones, health, internet, military, security

BMI’s (according to DARPA and David Axe) could begin as early as 2017 on humans. The plan is to use stentrodes. Testing has already proven success on sheep. I personally have concerns in both a health (as the article highlighted prone to blood clots) as well as anything connecting via Wi-Fi or the net with hackers trying to challenge themselves to prove anything is hackable; that before this goes live on a person we make sure that we have a more secure hack-resistant net before someone is injured or in case could injure someone else.


Soldiers could control drones with a thought.

A practical solution to mass-producing low-cost nanoparticles

Nanoparticles form in a 3-D-printed microfluidic channel. Each droplet shown here is about 250 micrometers in diameter, and contains billions of platinum nanoparticles. (credit: Richard Brutchey and Noah Malmstadt/USC)

USC researchers have created an automated method of manufacturing nanoparticles that may transform the process from an expensive, painstaking, batch-by-batch process by a technician in a chemistry lab, mixing up a batch of chemicals by hand in traditional lab flasks and beakers.
