This systematic review investigates the potential of bergamot, a polyphenol-rich citrus fruit, in improving osteosarcopenic obesity, a condition characterized by the simultaneous presence of osteoporosis, obesity, and sarcopenia. Bergamot extracts have been suggested to possess several pharmacological properties, including anti-inflammatory and antioxidant effects, which could be useful in the management of age-related diseases and neuromuscular health. The review highlights the promising effects of bergamot extracts on skeletal muscle mass and function, particularly in the context of obesity, metabolic syndrome, osteosarcopenic obesity, and osteoporosis. Furthermore, some studies have shown that bergamot extracts can improve the metabolic balance, endothelial function, and maximal oxygen uptake in athletes, highlighting their potential benefits for skeletal muscle health. Taken together, these results suggest that bergamot extracts, especially those rich in polyphenols, may be a valuable adjunct in the management of osteosarcopenic obesity and other associated clinical conditions involving pro-inflammatory effects on organs and tissues.

Integrating aging biomarkers and immune function to predict kidney health: insights from the future of families and child wellbeing study.

Biomarkers of biological aging predict health outcomes more accurately than chronological age. This study examines the relationship between aging biomarkers, immune function, and kidney health using the Future of Families and Child Wellbeing Study Biomarker Dataset. Using Wave 5 (year 9) and Wave 6 (year 15), we examined biomarker data from a total of 4898 individuals. The panel of aging biomarkers, comprised of epigenetic clocks (GrimAge, Horvath), immune function markers (CD8 + T cells, plasmablasts), and metabolic indicators (GDF-15, leptin), was evaluated in depth. We used principal component analysis (PCA) and K-means clustering for subtype identification. A random forest regressor was employed to predict kidney function using Cystatin C levels, and the importance of features was assessed. Three clusters with unique biological age and immune function profiles were identified. Cluster 1 had younger biological age markers. In Cluster 2, both GrimAge and GDF-15 levels were significantly increased, indicating an elevated risk for age-related diseases. According to predictive modeling, GrimAge, Pack Years, and immune function markers had the strongest influence on Cystatin C levels (R2 = 0.856). The incorporation of immune aging markers enhanced the predictive power, emphasizing the importance of immunosenescence in renal health. Aging biomarkers and immune function significantly impact kidney health prediction. The study results call for the utilization of extensive biomarker tests for individualized elderly care and early recognition of kidney deterioration. Clinical practice can be improved by incorporating biological age assessments for the prevention and management of age-related diseases.

Identification of potential sclerostin inhibiting flavonoids from Oroxylum indicum: an insilico approach

Flavonoids are secondary metabolites that are widely found in various medicinal plants. They are known for their medicinal benefits and have been extensively used in healthcare industries and in the management of age-related diseases. This paper focuses on flavonoids from Oroxylum indicum, a significant medicinal tree in the practice of traditional Indian medicine. O. indicum has been utilized in a variety of polyherbal formulations for the management of musculoskeletal disorders, however the mechanism of action of its bioactive flavonoids remains unknown. The present study aimed to identify the flavonoids of O. indicum with the potential to target sclerostin, an antagonist of canonical Wnt signaling pathway for the treatment of bone-related disorders. Molecular docking, coarse-grained and molecular dynamics simulations were performed to screen the major flavonoids and investigate their interaction with sclerostin. Flavonoids with highest binding affinity and interacting with at least one of the amino acids of the PNAIG motif residues were selected from docking studies and subjected to further drug likeness and ADMET screening. Further screening from coarse-grained and molecular dynamic simulations results showed that baicalein, compared to other screened flavonoids, stably binds with the important residues of the LRP6 binding site of sclerostin, resulting in pronounced structural changes in the protein. These findings suggest that baicalein from O. indicum can potentially inhibit sclerostin and can elicit skeletal protective effects, providing an insight for further in vitro and in vivo studies.

Natural Product Co-Metabolism and the Microbiota-Gut-Brain Axis in Age-Related Diseases.

Complementary alternative medicine approaches are growing treatments of diseases to standard medicine practice. Many of these concepts are being adopted into standard practice and orthomolecular medicine. Age-related diseases, in particular neurodegenerative disorders, are particularly difficult to treat and a cure is likely a distant expectation for many of them. Shifting attention from pharmaceuticals to phytoceuticals and "bugs as drugs" represents a paradigm shift and novel approaches to intervention and management of age-related diseases and downstream effects of aging. Although they have their own unique pathologies, a growing body of evidence suggests Alzheimer's disease (AD) and vascular dementia (VaD) share common pathology and features. Moreover, normal metabolic processes contribute to detrimental aging and age-related diseases such as AD. Recognizing the role that the cerebral and cardiovascular pathways play in AD and age-related diseases represents a common denominator in their pathobiology. Understanding how prosaic foods and medications are co-metabolized with the gut microbiota (GMB) would advance personalized medicine and represents a paradigm shift in our view of human physiology and biochemistry. Extending that advance to include a new physiology for the advanced age-related diseases would provide new treatment targets for mild cognitive impairment, dementia, and neurodegeneration and may speed up medical advancements for these particularly devastating and debilitating diseases. Here, we explore selected foods and their derivatives and suggest new dementia treatment approaches for age-related diseases that focus on reexamining the role of the GMB.

Medical ozone arrests oxidative damage progression and regulates vasoactive mediator levels in elderly patients (60-70years) with oxidative etiology diseases.

Medical ozone reestablishes cellular redox balance so that it may be a valid therapeutic approach in the prevention and management of age-related diseases with oxidative etiology in older people. The aim of this study is to evaluate oxidative stress and some vasoactive substances in elderly (60-70years) rheumatoid arthritis patients with diabetes and hypertension, as well as another group with bronchial asthma patients in order to demonstrate the beneficial effects of medical ozone in the prevention and therapy of age-related diseases in these age groups. A randomized clinical study with 45 older patients (60-70years) was performed. Group I (n = 15) with rheumatoid arthritis + diabetes and hypertension received no ozone treatment, and group II (n = 30) was treated with medical ozone. This group was divided into two subgroups (n = 15 each), group IIa: the same as group I + medical ozone and group IIb: bronchial asthma patients. Indicators of RA in I and IIa groups were evaluated. Redox balance was assessed through defense and injury biomarkers. Thromboxane A2 (TXA2) and prostacyclin levels were assessed in group IIb patients. Medical ozone arrested oxidative injury progression in the Ia group and decreased thromboxane levels and the TXA2/6-keto PGF1α ratio in the IIb group. Medical ozone arrested the progression of oxidative damage and modulated those endogenous mechanisms that promote a suitable redox status and TXA2/PGI2 balance. These results suggest that medical ozone may become a standard approach in the prevention and management of age-related oxidative diseases in elderly people.

Evaluating the Role of Probiotics in the Prevention and Management of Age-Related Diseases.

The human lifespan has been significantly increased due to scientific advancements in the management of disease; however, the health span of the aging population does not follow the same trend. Aging is the major risk factor for multimorbidity that is derived from the progressive loss of homeostasis, immunological and stem cell exhaustion, as well as exacerbated inflammation responses. Age-related diseases presenting with high frequencies include neurodegenerative, musculoskeletal, cardiovascular, metabolic diseases and cancer. These diseases can be co-morbid and are usually managed using a disease-specific approach that can eventually lead to polypharmacy, low medication adherence rates and undesired drug-drug interactions. Novel studies suggest targeting the shared biological basis of age-related diseases to retard the onset and manage their manifestations. Harvesting the anti-inflammatory and immunomodulatory capacity of probiotics to tackle the root cause of these diseases, could pose a viable alternative. In this article, a comprehensive review of the effects of probiotic supplementation on the molecular pathogenesis of age-related diseases, and the potential of probiotic treatments as preventative or alleviatory means is attempted. Furthermore, issues on the safety and efficiency of probiotic supplementation, as well as the pitfalls of current clinical studies are discussed, while new perspectives for systematic characterization of probiotic benefits on aged hosts are outlined.

Can Undergraduate Students Help Change Older Adults' Confidence for Making Nutrition-Related Decisions in a 45-Minute Nutrition Workshop?

Purpose: The Social Cognitive Theory (SCT) suggests health behaviour can be modified by enhancing knowledge of health benefits and outcome expectations of changing behaviour, improving self-efficacy (confidence), and developing goals to overcome barriers to behaviour change. This study aimed to determine the impact of student-led nutrition workshops on participants' confidence related to SCT constructs for making dietary choices that align with evidence-based nutrition recommendations.Methods: Level-4 Science students developed and delivered 9 workshops on nutrition recommendations for the prevention and management of age-related diseases. Participants attending the workshops completed pre- and post-surveys to assess SCT constructs. For each SCT construct, participants rated their confidence on a 10-point Likert scale. The number (%) of participants who rated their confidence as ≥8/10 on the pre- and post-surveys were compared using the χ2 test.Results: Sixty-three community members (60% female, mean ± SD age 71 ± 7 years) attended the workshops. The number of participants rating confidence as ≥8/10 for each SCT construct increased after the workshops (P < 0.05).Conclusion: Undergraduate students can positively influence community members' confidence for making nutrition-related decisions. Involving students in interventions where SCT-structured workshops are used may help conserve health care resources and reach older adults who may not have access to dietitian services.

Care of geriatric rabbits

With the continual advancement in veterinary medicine, rabbits have the care they need to live longer. While rabbits of all ages have similar needs, geriatric rabbits can have a longer, better quality of life with proper identification and management of age-related diseases. Important considerations for elevated quality of life for geriatric patients include: adjustments in husbandry and nutrition, and medical management of age-related diseases such as congestive heart failure, chronic renal insufficiency, and a wide variety of mobility issues. Becoming familiar with signs of age-related medical complications is extremely important due to a rabbit's natural instinct to hide signs of illness. Supportive care at home is key to the ongoing wellbeing of geriatric pets with health conditions. It is also important to be prepared to discuss the delicate subject of end-of-life care and euthanasia with owners of geriatric rabbits. Humane and stress-free euthanasia is important for all species, including pet rabbits.

Inflammation, telomere length, and grip strength: a 10-year longitudinal study.

Telomere attrition has been associated with age-related diseases, although causality is unclear and controversial; low-grade systemic inflammation (inflammaging) has also been implicated in age-related pathogenesis. Unpicking the relationship between aging, telomere length (TL), and inflammaging is hence essential to the understanding of aging and management of age-related diseases. This longitudinal study explored whether telomere attrition is a cause or consequence of aging and whether inflammaging explains some of the associations between TL and one marker of aging, grip strength. We studied 253 Hertfordshire Ageing Study participants at baseline and 10-year follow-up (mean age at baseline 67.1 years). Participants completed a health questionnaire and had blood samples collected for immune-endocrine and telomere analysis at both time points. Physical aging was characterized at follow-up using grip strength. Faster telomere attrition was associated with lower grip strength at follow-up (β = 0.98, p = 0.035). This association was completely attenuated when adjusted for inflammaging burden (p = 0.86) over the same period. Similarly, greater inflammaging burden was associated with lower grip strength at follow-up (e.g., interleukin [IL]-1β: β = -2.18, p = 0.001). However, these associations were maintained when adjusted for telomere attrition (IL-1β, p = 0.006). We present evidence that inflammaging may be driving telomere attrition and in part explains the associations that have previously been reported between TL and grip strength. Thus, biomarkers of physical aging, such as inflammaging, may require greater exploration. Further work is now indicated.

Molecular promiscuity of plant polyphenols in the management of age-related diseases: far beyond their antioxidant properties.

The use of plant-derived polyphenols for the management of diseases has been under debate in the last decades. Most studies have focused on the specific effects of polyphenols on particular targets, while ignoring their pleiotropic character. The multitargeted character of polyphenols, a plausible consequence of their molecular promiscuity, may suppose an opportunity to fight multifactorial diseases. Therefore, a wider perspective is urgently needed to elucidate whether their rational use as bioactive food components may be valid for the management of diseases. In this chapter, we discuss the most likely targets of polyphenols that may account for their salutary effects from a global perspective. Among these targets, the modulation of signalling and energy-sensitive pathways, oxidative stress and inflammation-related processes, mitochondrial functionality, epigenetic machinery, histone acetylation and membrane-dependent processes play central roles in polyphenols' mechanisms of action.Sufficient evidence on polyphenols has accumulated for them to be considered a serious option for the management of non-communicable diseases, such as cancer and obesity, as well as infectious diseases. The remaining unresolved issues that must be seriously addressed are their bioavailability, metabolite detection, specific molecular targets, interactions and toxicity. The Xenohormesis hypothesis, which postulates that polyphenols are the product of plant evolutive adaptation to stress and conferee their resistance to mammals, offers a reasonable explanation to justify the beneficial and non-toxic effects of plant mixtures, but do not fully meet expectations. Hence, future research must be supported by the use of complex polypharmacology approaches and synergic studies focused on the understanding of the pleiotropic effects of polyphenols. Revisiting polyphenol mechanisms of action with the help of these techniques may allow for the improvement of human health and wellness by using intelligent nutritional intervention.
