Aging has been considered a progressive decrease of a living organism homeodynamics , which indicates a reduction of the psycho-biological resilience. This narrative review provides an overview on the available literature related to the holistic approach of integrative medicine, psychoneuroendocrineimmunology (PNEI) and hormesis in aging process. On the basis of pathophysiology of cell senescence and of chronic degenerative diseases, possible preventive/therapeutic pathways have been examined. Chronic low grade cellular inflammation and chronic stress have been shown as the general interlinked factors inducing aging, on the basis of complex biochemical, cell and multi-organ derangements. The main cell degenerative processes which have been related to aging are: altered mitochondria DNA/metabolism, excessive oxidative stress, glycation, alteration of autophagy and proteasome, genome alterations. Literature about longevity-targeting interventions, beyond conventional medicine, describes a spectrum of possible measures to improve psycho-biological resilience, based on PNEI paradigm, on hormesis and upon mitochondria-targeted interventions. Calorie restriction, exercising, fasting, nutraceuticals, sleep regulation, specific breathing, meditation and psychotherapy are discussed, among others.
Objectives To compare two different medical compression stockings after varicose vein treatment. Patients and methods A randomized single-blind controlled study on two compression regimes after saphenous catheter foam sclerotherapy + phlebectomy was performed. After pads and 5 mmHg contention sock, 23 mmHg (group A, Struva 23®) or 35 mmHg (group B, Struva 35®) medical compression stocking was applied 24 h/day for seven days; subsequently 21-23 mmHg medical compression stocking in daytime. Symptoms, compliance, skin findings, and bioimpedance spectroscopy parameters were assessed. Results A total of 94 patients (48 and 49 limbs in groups A and B, respectively) were enrolled. Three (T3) and seven (T7) days post-operatively, most symptoms were significantly milder in group B, especially pain and heaviness at T7 and at day 40 (T40). Ambulation, medical compression stocking stability/tolerability and skin healing were significantly better in group B, with p = 0.046, 0.021/0.060, and 0.010, respectively, at T7. Bioimpedance parameters increased at T7 and decreased at T40 in both groups; leg reactance and limb L-Dex improved in group B at T7 and T40, respectively (p = 0.039 and 0.012). Conclusions Compression with 23 and 35 mmHg medical compression stocking after catheter foam sclerotherapy + phlebectomy was effective and well tolerated at immediate/short term. Compression with 35 mmHg medical compression stocking provided less adverse post-operative symptoms and better tissue healing. Bioimpedance results confirmed a slightly better edema improvement with 35 mmHg medical compression stocking.
Psychoneuroendocrineimmunology (PNEI) is the science which studies the interactions between psychological, neural, endocrine and immunological processes. The concept of the PNEI system was developed in the seventies and eighties through the discoveries of the interaction between immune system and molecules with neuroendocrine activity targeting multiple organs; the interdependence between immunological, psychological and neuroendocrine mechanisms has been elucidated through several studies subsequently. PNEI system is a self-regulation network which is involved in the homeostasis of the organisms, in the maintenance of chemical-physical-neuropsychological balance in response to stimuli of various nature. The present review provides an overview of the fundamental scientific literature on PNEI and its interaction with chronic low grade cellular inflammation processes and consequently with longevity. Similarly literature data on the strict link between hormetic processes and PNEI system are discussed, with reference to resilience as a key-factor in the natural/pathologic evolution of aging.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
