Precision medicine: the rifle vs. shotgun approach to cancer treatment
Why does one person respond favorably to lung cancer treatment while another does not? The answer lies in their DNA. Just 20 years ago, lung cancer was broadly categorized into two groups: non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC). Relatively recently, the treatment of NSCLC shifted from chemotherapy as a single treatment optionRead more …Precision medicine: the rifle vs. shotgun approach to cancer treatment originally appeared inKevinMD.com.

In conclusion, long-term cumulative BP was associated with subsequent cognitive decline, dementia risk, and all-cause mortality in cognitively healthy adults aged ≥50 years. Efforts are required to control long-term systolic BP and pulse pressure and to maintain adequate diastolic BP.

Republican Health Policies Disproportionally Harm White Citizens in Their States
BY MIKE MAGEE
“As I’ve said before, I believe Dr. Ladapo is an anti-science quack who doesn’t belong anywhere near our state’s Surgeon General office, let alone running it. But now that he’s been confirmed, it’s my sincere hope that he and Governor DeSantis choose to focus on saving lives and preventing unnecessary illness instead of continuing their absurd promotion of conspiracy theories and opposition to proven public health measures — but I’m not going to hold my breath.”
If you identified these as the words of the former governor, and now Congressman Charlie Crisp, currently running to retake t...

Cancer Correlates with Increased Risk of Later Onset of Type 2 Diabetes
Researchers here note a correlation between cancer diagnosis and greater risk of later onset of type 2 diabetes. A reasonable guess is that this is mediated by the increased burden of cellular senescence produced by chemotherapy and radiotherapy, though, as the researchers point out, the widely different risks by cancer type may indicate that tumors are metabolically active in ways that specifically promote the metabolic dysfunction that leads to type 2 diabetes.
For patients with cancer, prevalent type 2 diabetes at the date of cancer diagnosis is associated with increased cancer-specific and all-cause mortality....

Photonic Technique for Deeper Fluorescent Sensors
Researchers at MIT have developed a method that lets them read the signal from fluorescent sensors that are as deep as 5.5 centimeters in tissue. Previously, it was very difficult to get a good signal from a fluorescent sensor placed that deep, as fluorescence emitted by the tissue itself would muddy the signal. The new technique involves using a laser with an oscillating wavelength to illuminate the fluorescent sensor, resulting in the emitted fluorescence to double its frequency. This allows the researchers to easily pick out the fluorescence signal from the background noise. The new method could allow for new applicatio...

This study examines evidence suggesting that mitochondrial dysfunction plays a significant early impact on AD pathology.
Although mitochondrial dysfunction is a typical indication of Alzheimer's disease, it is unclear whether the cellular systems that maintain mitochondrial integrity malfunction, aggravating mitochondrial pathology. Different levels of vigilance and preventive methods are used to reduce mitochondrial damage and efficiently destroy faulty mitochondria to maintain the mitochondrial equilibrium. The form and function of mitochondria are regulated by mitochondrial fusion and fission. In contrast, mitoch...

How patient education can save lives
A patient undergoing chemotherapy for breast cancer was diagnosed on April 20th with profound secondary adrenal insufficiency (hypophysitis: ACTH undetectable, cortisol 0.2) caused by immunotherapy (pembrolizumab). She was started on corticosteroids and sent home from the hospital on April 24th with a prescription for only five days of prednisone. After completing the five days ofRead more …How patient education can save lives originally appeared inKevinMD.com. (Source: Kevin, M.D. - Medical Weblog)

The Power of an Infrared Sauna
Years ago, I co-created a show on Youtube called The Wellness Experiment for my old company LEAFtv. In each episode we would try out a new, and sometimes controversial, (hello V-steams!) wellness treatments. I remember, vividly, one of my favorite episodes, by far, was the cold plunge followed by an infrared sauna, episode. In fact, of all the varying practices we tried out, the way I felt after this treatment stuck out as the most impactful - my body just felt different. More alive? energetic? I’m not sure what, but I just felt good.
Despite promises to myself to keep up with this practice, as life does, I let ...

Navitoclax is Better than Dasatinib and Quercetin at Clearing Senescent Cells Produced by Radiotherapy
It is now well known that many of the negative consequences resulting from chemotherapy and radiotherapy are mediated by a raised burden of senescent cells. One of the goals of cancer therapy is to drive cancerous cells into senescence: better to have senescent cells than cancerous cells! Nonetheless, gaining a greater burden of senescent cells is literally accelerated aging, as these additional senescent cells actively degrade tissue function and create chronic inflammation via their secretions. Thus senolytic therapies should be of great benefit to cancer survivors, removing this harmful side-effect of cancer therapy.

Cancer
I just finished reading The Emperor of All Maladies: A biography of cancer, by Siddhartha Mukherjee. I have a quibble with the title -- it should be history, not biography. By personifying cancer, he plays into just the mythologizing he is trying to dispel. But that aside, I found the book very informative. I knew the general outline of the story, but not a lot of the details. What I want to comment on here, which I believe is the key takeaway, is that medical practice is subject to ideological capture, even in the modern era of " scientific " medicine. In the center of the book is the horror story of radical mastecto...

Wireless Implant for Anti-Cancer Photodynamic Therapy
Researchers at Texas A&M University created a wireless device that aims to illuminate and destroy residual tumor cells left after cancer resection. The device can be used by surgeons to illuminate the tumor bed after resection. It works in combination with a photosensitizer drug that is administered before the procedure and accumulates in tumor cells, making them vulnerable to the lethal effects of the delivered light. The small device can also be implanted within the body, potentially to provide longer term photodynamic therapy and guard against cancer recurrence.
For many cancers, surgery is the primary treatment,...

Senolytics as a Treatment for Intervertebral Disc Degeneration
Degenerative disc disease is commonplace, and in recent years research has implicated the age-related accumulation of senescent cells in the onset and progression of this condition. Senolytic drugs to clear senescent cells may thus be a useful treatment. Existing senolytics, such as the dasatinib and quercetin combination, could be applied to many age-related conditions, since senescent cells and their inflammatory secretions produce broad negative effects on cell and tissue function. Unfortunately there is little funding and financial incentive for academic organizations to run clinical trials for even a significant fract...

This study tests the feasibility of chronically elevating skeletal muscle NAD+ in mice and investigates the putative effects on mitochondrial respiratory capacity, insulin sensitivity, and gene expression. The metabolic effects of NR and PT treatment were modest. We conclude that the chronic elevation of skeletal muscle NAD+ by the intravenous injection of NR is possible but does not affect muscle respiratory capacity or insulin sensitivity in either sedentary or physically active mice. Our data have implications for NAD+ precursor supplementation regimens.
