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...

A Look Back at 2020: Progress Towards the Treatment of Aging as a Medical Condition
While I suspect that COVID-19 will feature prominently in most retrospectives on 2020, I'll say only a little on it. The data on mortality by year end, if taken at face value, continues to suggest that the outcome will fall at the higher end of the early estimates of a pandemic three to six times worse than a bad influenza year, ten times worse than a normal influenza year. The people who die are near entirely the old, the co-morbid, and the immunocompromised. They die because they are suffering the damage and dysfunction of aging. Yet the societal conversation and the actions of policy makers ignore this. There is ...

In this study, we show that calorie restriction is protective against age-related increases in senescence and microglia activation and pro-inflammatory cytokine expression in an animal model of aging. Further, these protective effects mitigated age-related decline in neuroblast and neuronal production, and enhanced olfactory memory performance, a behavioral index of neurogenesis in the SVZ. Our results support the concept that calorie restriction might be an effective anti-aging intervention in the context of healthy brain aging. Greater Modest Activity in Late Life Correlates with Lower Incidence of Dementia ...

In this report, we propose that the molecular mechanisms of beneficial actions of CR should be classified and discussed according to whether they operate under rich or insufficient energy resource conditions. Future studies of the molecular mechanisms of the beneficial actions of CR should also consider the extent to which the signals/factors involved contribute to the anti-oxidative, anti-inflammatory, anti-tumor and other CR actions in each tissue or organ, and thereby lead to anti-aging and prolongevity.

This study indicates that frailty and other age-related diseases could be prevented and significantly reduced in older adults. Getting our heart risk factors under control could lead to much healthier old ages. Unfortunately, the current obesity epidemic is moving the older population in the wrong direction, however our study underlines how even small reductions in risk are worthwhile." The study analysed data from more than 421,000 people aged 60-69 in both GP medical records and in the UK Biobank research study. Participants were followed up over ten years. The researchers analysed six factors that could impact on...

This study cohort is a healthy subset of the EpiPath cohort, excluding all participants with acute or chronic diseases. With a mediation analysis we examined whether CMV titers may account for immunosenescence observed in ELA. In this study, we have shown that ELA is associated with higher levels of T cell senescence in healthy participants. Not only did we find a higher number of senescent cells (CD57+), these cells also expressed higher levels of CD57, a cell surface marker for senescence, and were more cytotoxic in ELA compared to controls. Control participants with high CMV titers showed a higher number of senes...

Discussions of radical life extension, technological acceleration, and artificial general intelligence were far more fringe concerns back then than is now the case, but this growth in awareness isn't a coincidence. Visions slowly become reality because people work to make that happen. Technological progress is not accidental: it is led by our desires. I should say that de Magalhães is here generous in not passing judgement on the value (or lack thereof) of most of the various ventures and classes of approach he surveys. But some approaches are definitely better than others, and to my eyes one the principal challeng...

This study is a good example of the degree to which the choice to remain active in later life makes a difference. That implies a range of other choices over the decades in order to raise the odds that you can in fact choose to remain active when older, such as avoiding weight gain. Moderate physical activity is associated with a greater than 50% reduction in cardiovascular death in over-65s. The 12 year study in nearly 2500 adults aged 65 to 74 years found that moderate physical activity reduced the risk of an acute cardiovascular event by more than 30%. High levels of physical activity led to greater risk reducti...

This study demonstrates that TNTs play a significant part in the intercellular transfer of α-synuclein fibrils and reveals the specific role of lysosomes in this process. This represents a major breakthrough in understanding the mechanisms underlying the progression of synucleinopathies. These compelling findings, together with previous reports from the same team, point to the general role of TNTs in the propagation of prion-like proteins in neurodegenerative diseases and identify TNTs as a new therapeutic target to combat the progression of these incurable diseases.

This study offers one useful data point, as the authors describe a genetic alteration that can boost the supply of new immune cells in old mice. The decline in that supply with age is one of the factors leading to poor immune function - and that means more than just vulnerability to infections, as the immune system is also responsible for destroying potentially cancerous and senescent cells, as well as clearing out forms of damaged proteins and unwanted metabolic waste. Various possibilities for increasing the number of new immune cells already exist in principle, such as regenerating the thymus, or cell therapies in which...
