Using MRI to Help Destroy Tumors
Researchers at the University College London (UCL) have figured out a way to kill lethal brain tumors by using MRI to heat up a magnetic metal “seed” to destroy cancer cells. The groundbreaking science was first introduced at The Cheltenham Science Festival in early June.The seed is injected into the subject ’s bloodstream and navigated toward the cancer. The MRI kills the tumor by heating up the seed. According to a reportfromThe Telegraph, the heat only targets the cancer cells and keeps the surrounding cells and tissue safe. “We can guide it with real precision avoiding any areas that we don’t want to go to...

Hairy Frosted Glass Slides Capture Circulating Tumor Cells for Screening and Early Diagnosis
Biopsies are typically the way prostate cancer is identified, but prostate cancers also release circulating tumor cells (CTCs) that are telltale signs of the presence of the disease. Because they’re so rare and difficult to separate from whole blood, CTCs remain rarely used for establishing diagnoses.
Researchers from the Chinese Academy of Scientists have now developed a cheap and easy way to capture CTCs using silica nanowires grown on frosted glass slides and antibodies that make the connection to the cancer cells.
The silica nanowires were grown directly on the glass slides, following which a special adhesion mol...

Over-Screening, Rigid Protocols, and Changing Guidelines: A Personal Journey Through the Looking-Glass
by Craig Klugman
A new JAMAarticle reports on a US Preventive Services Task Force recommendation against routine ECG in patients without symptoms of heart disease: “For asymptomatic adults at low risk of CVD events (individuals with a 10-year CVD event risk less than 10%), it is very unlikelythat the information from resting or exercise ECG (beyond that obtained with conventional CVD risk factors) will result in a change in the patient’s risk category….”The report states that over-screening can lead to harms such as “invasive procedures, overtreatment, and labeling.”Such advice follows with recent suggestions a...

AMA Rejects Recommendation to Reaffirm Opposition to Medical Aid in Dying
The American Medical Association (AMA) House of Delegates
today voted 53 to 47 percent to reject a report by its Council on Ethical and Judicial Affairs (CEJA)
that recommended the AMA maintain its Code of Medical Ethics’ opposition to
medical aid in dying. Instead, the House of Delegates referred the report back
to CEJA for further work.
The
AMA Code of Medical Ethics Opinion 5.7 adopted 25 years ago in 1993 before
medical aid in dying was authorized anywhere in the United States says:
“...permitting physicians to engage in assisted suicide would ultimately cause
more harm than good. Physician-assisted suic...

Oisin Biotechnologies CSO John Lewis at Undoing Aging
Oisin Biotechnologies is one of a number of companies to have emerged from our community in recent years, from the network of supporters and researchers connected to the Methuselah Foundation and SENS Research Foundation. The Oisin principals are working with a platform capable of selectively destroying cells based on the internal expression of specific proteins. Their initial targets are senescent cells, one of the root causes of aging, and cancerous cells, one of the consequences of aging. They will be taking a therapy for cancer into clinical trials initially, as it is somewhat less challenging to move viable cancer tre...

More Men Choosing Less Aggressive Treatment for Low-Risk Prostate Cancer
Prostate cancer is the most common form of cancer for men but it often does not present in an aggressive form of the disease. It now appears that more men with this type of prostate cancer are now, appropriately, foregoing aggressive treatment of the disease (see:More men with low-risk prostate cancer are forgoing aggressive treatment). Below is an excerpt from an ariticle on this topic:American doctors are successfully persuading increasing numbers of men with low-risk prostate cancer to reject immediate surgery and radiation in favor of surveillance, a trend that is sparing men's sexual health without increasin...

The Ethics of Keeping Alfie Alive
By SAURABH JHA
Of my time arguing with doctors, 30 % is spent convincing British doctors that their American counterparts aren’t idiots, 30 % convincing American doctors that British doctors aren’t idiots, and 40 % convincing both that I’m not an idiot.
A British doctor once earnestly asked whether American physicians carry credit card reading machines inside their white coats. Myths about the NHS can be equally comical. British doctors don’t prostate every morning in deference to the NHS, like the citizens of Oceania sang to Big Brother in Orwell’s dystopia. Nor, in their daily rounds, do they calculate opportun...

The fall of the digital rectal exam
For almost 20 years, the value of the digital rectal exam (DRE), a long time staple of the complete examination of the trauma patient, has been questioned. Performing a rectal examination on all trauma patients is no longer advocated except for a few specific indications.
As recently as two months ago, trauma surgeon Michael McGonigal blogging at the Trauma Pro reinforced the message. Because a rectal examination is so uncomfortable for patients already traumatized and its yield is so minimal, he advocates doing it in only patients with spinal cord injury, pelvic fracture, and penetrating abdominal trauma. For a more ext...

Heal thyself before others
Alice wept in my arms as she described her father’s last days. He died of metastatic prostate cancer. She felt lighter as she shared beautiful memories of him. It will never be the same for Alice, nor will it be for me. I was running behind for my next patient, a healthy 86-year-old woman. I apologized for keeping her waiting. She did not mind; she knew I would give her the time she needed. She held my hand as she unburdened her recent challenges caring for her husband after his vascular surgery. As dictated by her insurance carrier, she had minimal services. To my frustration, I could not in my power, get her the help s...

New study once again casts doubt on PSA screening
This study adds to the discouraging screening literature, and again, simply does not support screening of asymptomatic individuals,” he said.
Fortunately, Garnick added, men diagnosed with prostate cancer following a PSA test may not have to be treated either in the short or long term. Depending on tumor characteristics, some can opt to have their cancer monitored with active surveillance, which relies on periodic prostate biopsies or MRI to look for new signs that treatment may be necessary. “Hopefully, current research that uses sophisticated genetic testing or biomarkers of prostate cancer may help provide more prec...
