Cancer Survivors Exhibit Greater Risk of New Cancers and Higher Mortality Due to those Cancers
The objective of this study is to quantify the overall and cancer type-specific risks of subsequent primary cancers (SPCs) among adult-onset cancer survivors by first primary cancer (FPC) types and sex. Among 1,537,101 survivors (mean age, 60.4 years; 48.8% women), 156,442 SPC cases and 88,818 SPC deaths occurred during 11,197,890 person-years of follow-up (mean, 7.3 years). Among men, the overall risk of developing any SPCs was statistically significantly higher for 18 of the 30 FPC types, and risk of dying from any SPCs was statistically significantly higher for 27 of 30 FPC types as compared with risks in the general po...

In conclusion, our study demonstrated that the molecular processes of aging are relatively subtle in their progress, and the aging process of every tissue depends on the tissue's specialized function and environment. Hence, individual gene or process alone cannot be described as the key of aging in the whole organism.
Mouse Age Matters: How Age Affects the Murine Plasma Metabolome
A large part of metabolomics research relies on experiments involving mouse models, which are usually 6 to 20 weeks of age. However, in this age range mice undergo dramatic developmental changes. Even small age differences may l...

DICER is Necessary for the Metabolic Benefits of Exercise
Exercise beneficially influences fat tissue metabolism, and researchers here find that the protein DICER is necessary for these benefits to take place. Expression of DICER declines with age, but is increased by structured exercise programs - though to a very variable degree. This variability suggests that a great deal more exploration is needed in order to understand this portion of the diverse set of mechanisms by which exercise improves health. DICER is just one part of a network of signals and regulators, and much is yet to be cataloged of their interactions.

In this study, except for the reduction in body weight, the aging characteristics related to epidermal and muscle tissue in mice were significantly ameliorated in the CR group compared with the control group. Additional studies have indicated that not stem cells themselves but the stem cell microenvironment is the key factor mediating stem cell activation, proliferation and differentiation.
Mitochondrial dysfunction is an important factor leading to age-related muscular atrophy. Considering the dependence of skeletal muscle on ATP, loss of mitochondrial function, which can lead to a decrease in strength and enduranc...

A Tour of Longevity Industry Therapies Presently in Clinical Trials
The longevity industry is presently still quite young, a hundred and something companies that are largely still at the preclinical stage of development, most founded in the last couple of years. Even if we want to be broadly generous as to which companies and projects are to be included in our definition of the industry, no newly developed therapies to treat the mechanisms of aging have yet been approved by the FDA, although a few have made it to phase 3 clinical trials. This is just a matter of time, however; it can take a decade of hard work to go from an idea to an approved therapy, and very few longevity industry compa...

This study conclusively demonstrates the long-speculated relationship between aging, gene regulation, and somatic damage. The results open up new avenues of research with practical implications. If the same level of coordination reduction between genes is indeed a leading cause for aging phenomena, there may be a need to change course in current efforts to develop aging treatments.

Palliative care and the importance of holding space [PODCAST]
“Holding space means being physically, mentally, and emotionally present for someone. It means putting your focus on someone to support them as they feel their feelings. An important aspect of holding space is managing judgment while you are present. Like when you tell a patient that they have stage IV pancreatic cancer and that it […]Find jobs at Careers by KevinMD.com. Search thousands of physician, PA, NP, and CRNA jobs now. Learn more.

Medical aid in dying is not assisted suicide [PODCAST]
“To help the reader understand the issues better, I would like to relate some stories. A friend of mine was dying of pancreatic cancer. He had an implantable morphine pump and was on both hospice and palliative care. Still, he found that his suffering was unbearable and wanted to die sooner.

In this study, young adult mice were submitted to endurance exercise training and the function, differentiation, and metabolic characteristics of satellite cells were investigated in vivo and in vitro.
We found that injured muscles from endurance-exercised mice display improved regenerative capacity, demonstrated through higher densities of newly formed myofibres compared with controls (evidenced by an increase in embryonic myosin heavy chain expression), as well as lower inflammation (evidenced by quantifying CD68-marked macrophages), and reduced fibrosis. Enhanced myogenic function was accompanied by an increased ...

Intermittent Fasting Improves Biomarkers in Metabolic Syndrome Patients
There is a blurry gray area between intermittent fasting and time restricted feeding. The study here is somewhere in that zone, as the participants did eat daily, with less fasting time between meals than would be the case for, say, alternate day fasting. Time spent hungry does appear to be influential to the outcome, but perhaps less so than overall calories consumed. Inevitably, people eat fewer calories if given less time in which to consume calories. Unsurprisingly, eating less improves metrics in people with metabolic syndrome, a condition achieved by being overweight as a result of eating too much. The point of inter...

A Conservative View of Targeting NAD+ Metabolism in Diseases of Aging
NAD+ metabolism in the context of aging and age-related disease is an area of some interest of late. NAD+ is involved in mitochondrial function, essential to cell and tissue function. The mechanisms of synthesizing and recycling NAD+ decline with age, and this might be an important contributing factor in the decline of mitochondrial function throughout the body. Certainly, the evidence in cells and animals suggests that mitochondrial function can be improved via restoration of youthful levels of NAD+.
Given that the available ways of manipulating NAD+ metabolism largely involve supplementation with vitamin B3 deriva...

Microfluidic Device to Test Pancreatic Cancer Drugs
Certain varieties of pancreatic cancer exhibit multiple tumor cell subtypes that work, somewhat mysteriously, to quickly become resistant to chemotherapy agents. Researchers at Purdue University have now built a unique microfluidic device that can be used to test a cancer drug on multiple tumor cells subtypes. Using this technology the researchers believe that new drug therapies can be discovered and existing medicines used more effectively.
“The drug discovery and screening process has been using one cancer cell subtype and studying how it interacts with neighboring non-cancer cells, but this may overestimate the eff...

This study is the first to provide a direct link between this inflammation and plaque development - by way of IFITM3.
Scientists know that the production of IFITM3 starts in response to activation of the immune system by invading viruses and bacteria. These observations, combined with the new findings that IFITM3 directly contributes to plaque formation, suggest that viral and bacterial infections could increase the risk of Alzheimer's disease development. Indeed, researchers found that the level of IFITM3 in human brain samples correlated with levels of certain viral infections as well as with gamma-secretase activ...

Targeting Cellular Senescence to Heal Non-Healing Wounds
An accumulation of senescent cells takes place throughout the body with age. Cells become senescent constantly, the vast majority as a consequence of hitting the Hayflick limit on replication of somatic cells. In youth, these cells are efficiently removed, either via programmed cell death, or destroyed by the immune system. In later life, removal processes slow down, while the damaged state of tissue provokes ever more cells into becoming senescent. In older people, this imbalance leads to a state in which a few percent of all cells in tissues are senescent at any given time. This is, unfortunately, more than enough to pro...
