🧬🩸 Organ aging signatures in the plasma proteome track health and disease. 🧬🩸

The onset and effects of aging vary from individual to individual. Animal studies showed aging varies within the organs of an individual also. As we age our cells undergo different biochemical changes, leading to the deterioration of tissues and multiple age-related chronic diseases and eventually mortality. However, current knowledge on molecular change in organs is limited.🔬

This study shows large scale plasma proteomics data together with machine learning can measure organ health and aging in the living population. It showed different rates of aging in the organs of individuals.📌

🧬🧠 Genetic networks of Alzheimer's disease, aging, and longevity in humans. 🧬🧠

Human genomic analysis and genome-wide association studies (GWAS) have identified genes that are risk factors for early and late-onset Alzheimer’s disease (AD genes). Prior research has concentrated on a particular group of genes that have been demonstrated to either cause or be a risk factor for AD, even though the genetics of aging and longevity have been thoroughly examined. Therefore, it is unclear how the genes linked to AD, aging, and lifespan are related to one another.

In this study, using human gene sets successfully identified and overviewed the gene–gene networks of aging and longevity and their association with Alzheimer’s disease genes. The Reactome analysis provides the genetic pathways with gene set enrichment and statistical confidence levels. The genetic hallmarks identified will provide unexpectedly broad mechanisms, suggesting a wide variety of implications in the field of aging.

🧠💡 Grading of IDH‑mutant astrocytoma using diffusion, susceptibility, and perfusion‑weighted imaging. 🧠💡

The accurate grading of IDH-mutant astrocytoma is essential to develop therapeutic strategies and evaluating the prognosis of patients. A preoperative classification of these entities could be beneficial for the treatments of patients, particularly in those who have a contraindication to surgery or in cases where the lesions are unresectable. 🔄

This study demonstrated that DWI, SWI, and DSC-PWI are useful for assessing the tumor grade in IDH-mutant astrocytomas. The diagnostic precision of grading IDH mutant astrocytomas may be enhanced by the combination of ADCmin, ITSS, and rCBVmax. This study proposed that the combination of these advanced techniques could improve the diagnostic efficacy in grading IDH-mutant astrocytic gliomas. 🩸

🧬🏃‍♂️ Healthy lifestyle in late-life, longevity genes, and life expectancy among older adults: A 20-year, population-based, prospective cohort study. 🧬🏃‍♂️

Promoting healthy aging is crucial for individual and societal health. Studies show that following a healthy lifestyle, including not smoking, limiting alcohol, being active, and eating well, reduces the risk of chronic diseases and death. This lifestyle also correlates with a longer life, especially if adopted early. Modifying these habits in midlife can lead to a longer life without major diseases like diabetes, cardiovascular disease, and cancer.

In this study of Chinese older adults, maintaining a healthy lifestyle was linked to a lower risk of death and a moderate increase in life expectancy. These benefits were more pronounced among those with a high genetic risk of shorter lifespan. Ideal physical activity was found to have the most significant impact on reducing mortality. While previous studies have shown that a healthy lifestyle can reduce the risk of major health issues in older individuals, its effect on lifespan has been less explored.

🏃‍♀️🏋️‍♂️ Physical activity has a stronger correlation with arterial stiffness than strength, balance, or BMI in an older population. 🏃‍♀️🏋️‍♂️

Arterial stiffness is associated with several health conditions such as diabetes, hypertension, and cardiovascular diseases. Although it is impossible to stop the natural process of aging, there are factors that may help to slow this age-associated increase in arterial stiffness. A reduction in sedentary behavior has been found to be highly associated with a slowing of the natural progression of age-related stiffening of the arteries. 🚶‍♂️

This study reinforces the importance of habitual, lifelong physical activity in maintaining arterial health in an older population. Also, the adverse effect of high systolic blood pressure, increasing age and overall numbers of cardiovascular risk factors had a stronger ability to predict arterial stiffness in an older population than fitness-based tests. ❤️

🎯💊 Easy-to-find irAEs can be used as indicators to predict neoadjuvant chemo-immunotherapy response. 🎯💊

Lung cancer is the prominent cause of cancer-related deaths worldwide. Non-small cell lung cancer (NSCLC) patients are diagnosed with early-stage disease in only 25% of cases, making them amenable to surgery with a curative goal. The development of neoadjuvant therapy made it possible for locally advanced patients to accept surgical resection, and the addition of immunotherapy further improve the pathological outcomes of these patients. 🔍

This clinical trial showed that the immunotherapy-related rash may be associated with pathological outcomes, demonstrating that basic irAEs like rash can be used as indicators to predict response to neoadjuvant chemo-immunotherapy. For patients with resectable NSCLC, this might result in a favorable therapeutic outcome as suggested by some irAEs. 💉
