The integration of multidisciplinary tumor boards (MTBs) is fundamental in delivering state-of-the-art cancer treatment, facilitating collaborative diagnosis and management by a diverse team of specialists. Despite the clear benefits in personalized patient care and improved outcomes, the increasing burden on MTBs due to rising cancer incidence and financial constraints necessitates innovative solutions. The advent of artificial intelligence (AI) in the medical field offers a promising avenue to support clinical decision-making. This review explores the perspectives of clinicians dedicated to the care of cancer patients-surgeons, medical oncologists, and radiation oncologists-on the application of AI within MTBs. Additionally, it examines the role of AI across various clinical specialties involved in cancer diagnosis and treatment. By analyzing both the potential and the challenges, this study underscores how AI can enhance multidisciplinary discussions and optimize treatment plans. The findings highlight the transformative role that AI may play in refining oncology care and sustaining the efficacy of MTBs amidst growing clinical demands.

Searching for Beauty and Health: Aging in Women, Nutrition, and the Secret in Telomeres.

Women typically outlive men, yet they often experience greater frailty and a higher incidence of chronic diseases as they age. By exploring the biological foundations of aging, with a particular focus on telomere dynamics, this manuscript aims to describe how dietary and lifestyle choices can significantly influence the aging process. The review comprehensively examines current research, underscoring the power of nutrition to counteract age-related changes, support healthy aging, and maintain vitality and beauty in women. The exploration of telomeres-the protective caps at the ends of chromosomes-reveals how they serve as markers of cellular aging and are potential targets for interventions aimed at enhancing women's longevity and quality of life. This study also emphasizes the importance of sex-specific approaches and precision medicine in understanding the unique health challenges women face as they age. By proposing targeted strategies, the review seeks to address these challenges, offering insights into preventive measures that can foster resilience, promote well-being, and extend healthy life expectancy in women. Ultimately, this work provides a sophisticated understanding of the aging process in women, highlighting the pivotal role of tailored interventions in preserving both health and beauty.

Aging, Cancer, and Inflammation: The Telomerase Connection.

Understanding the complex dynamics of telomere biology is important in the strong link between aging and cancer. Telomeres, the protective caps at the end of chromosomes, are central players in this connection. While their gradual shortening due to replication limits tumors expansion by triggering DNA repair mechanisms, it also promotes oncogenic changes within chromosomes, thus sustaining tumorigenesis. The enzyme telomerase, responsible for maintaining telomere length, emerges as a central player in this context. Its expression in cancer cells facilitates the preservation of telomeres, allowing them to circumvent the growth-limiting effects of short telomeres. Interestingly, the influence of telomerase extends beyond telomere maintenance, as evidenced by its involvement in promoting cell growth through alternative pathways. In this context, inflammation accelerates telomere shortening, resulting in telomere dysfunction, while telomere elements also play a role in modulating the inflammatory response. The recognition of this interplay has promoted the development of novel therapeutic approaches centered around telomerase inhibition. This review provides a comprehensive overview of the field, emphasizing recent progress in knowledge and the implications in understanding of cancer biology.

Aberrant telomeric structures and serum markers of telomere dysfunction in healthy aging: a preliminary study.

Telomeres undergo a progressive shortening process as individuals age, and it has been proposed that severely shortened and dysfunctional telomeres play a role in the aging process and the onset of age-related diseases in human beings. An emerging body of evidence indicates that the shortening of telomeres in cultured human cells is also influenced by other replication defects occurring within telomeric repeats. These abnormalities can be detected on metaphase chromosomes. Recent studies have also identified a set of serological markers for telomere dysfunction and DNA damage (elongation factor 1α [EF-1α], stathmin, and N-acetyl-glucosaminidase). With this study, the correlation between telomere abnormalities (by FISH) and these biomarkers as measured in blood serum (by ELISA) from a cohort of 22 healthy subjects at different ages (range 26-101 years) was analyzed. A strong positive correlation between aging and the presence of aberrant telomere structures, sister telomere loss (STL), and sister telomere chromatid fusions (STCF) was detected. When serum markers of telomere dysfunction were correlated with telomere abnormalities, we found that stathmin correlated with total aberrant telomeres structures (r = 0.431, p = 0.0453) and STCF (r = 0.533, p = 0.0107). These findings suggest that serum stathmin can be considered an easy-to-get marker of telomere dysfunction and may serve as valuable indicators of aging.

Dysglycemia, gender, and cognitive performance in older persons living with mild cognitive impairment: findings from a cross-sectional, population-based study.

OBJECTIVE: This study aims to examine the relationship between dysglycemia - also known as pre-diabetes or impaired glucose tolerance- and cognitive abilities in an older population living Mild Cognitive Impairment (MCI) and stratified by gender. STUDY DESIGN: This is a retrospective study with data gathered from a large Italian clinical-based database. MAIN OUTCOME MEASURES: The evaluation of cognitive performances by the Mini-Mental State Examination and the Addenbrooke's Cognitive Examination Revised rating scale as tests of screening and a comprehensive neuropsychological evaluation of several cognitive areas. RESULTS: The study comprised 682 subjects (445 F/237 M) with a mean age of 76.08 ± 9.03 (range: 66-93) years. In all population, subjects with dysglycemia 193 (28.3%) had significantly poorer performance in memory (p = 0.006) and logic reasoning (p = 0.007) when compared with subjects without dysglycemia. The linear regression analyses revealed significant differences in the correlates of cognitive domains between gender groups. Independent of multiple covariates, women with dysglycemia showed worse performances in attention and short-term memory domains as compared with men. Even in the absence of dysglycemia women were more likely to show lower score in screening test of general cognition and attention. CONCLUSIONS: Our findings suggest that dysglycemia in older individuals with MCI is associated with declines in specific cognitive domains, potentially influenced by gender. Implementing a comprehensive approach involving risk stratification and preventive strategies may be more effective in averting further cognitive decline in this high-risk population.

Geroscience and the Fight Against Alzheimer's Disease: Between Myth and Reality.

 Aging is associated with a gradual decline in cellular stability, leading to a decrease in overall health. In the brain, this process is closely linked with an increased risk of neurodegenerative diseases, including Alzheimer's disease. Understanding the mechanisms of brain aging is crucial for developing strategies aimed at enhancing both lifespan and health span. Recent advancements in geroscience, the study of the relationship between aging and age-related diseases, have begun to redefine our understanding of Alzheimer's disease, guiding the development of preventive medical strategies that target the aging process itself rather than merely addressing the symptomatic manifestations of the disease.

Sarcopenia: A dive into metabolism to promote a multimodal, preventive, and regenerative approach.

Sarcopenia, the age-related loss of skeletal muscle mass and function, poses a significant challenge in the field of geriatrics and gerontology, impacting the health and independence of older adults. Understanding and addressing sarcopenia is crucial for optimizing clinical outcomes and enhancing the quality of life along with aging. By synthesizing current research findings and theoretical frameworks, this review elucidates the multifaceted mechanisms underlying sarcopenia, mainly focusing on energy balance and metabolic processes. Furthermore, the manuscript explores the implications of sarcopenia on overall health outcomes, functional decline, and quality of life in older individuals. The study concludes with a perspective on the role of preventive and regenerative medicine in sarcopenia, where the two main lifestyle pillars (exercise and diet) represent key factors.

Tai chi, irisin and cognitive performance: a clinical and biological investigation in older adults.

BACKGROUND: Skeletal muscle is the main source of circulating irisin, both at rest and during physical activity. Previous studies have suggested that irisin can improve cognitive abilities. AIMS: We explored whether six months of Tai Chi (TC) practice can modulate such a relationship in healthy older persons. METHODS: This is a prospective clinical study to evaluate the effects of TC practice as compared with low intensity exercise (LI) and no exercise (NE) control groups on plasmatic irisin levels and cognitive performance. Forty-two healthy older persons were stratified into three groups according to physical activities. Biochemical assay and cognitive functions were assessed at the baseline and after six months. RESULTS: A significant change was found in circulating irisin levels in TC as compared with NE group (p = 0.050) across time. At six months in TC group irisin levels significantly correlated with a verbal memory test (p = 0.013) controlled by age and education. CONCLUSION: Our results suggest the potential benefits for cognitive health of TC practice by irisin levels modulation.

Focus on senescence: Clinical significance and practical applications.

The older population is increasing worldwide, and life expectancy is continuously rising, predominantly thanks to medical and technological progress. Healthspan refers to the number of years an individual can live in good health. From a gerontological viewpoint, the mission is to extend the life spent in good health, promoting well-being and minimizing the impact of aging-related diseases to slow the aging process. Biologically, aging is a malleable process characterized by an intra- and inter-individual heterogeneous and dynamic balance between accumulating damage and repair mechanisms. Cellular senescence is a key component of this process, with senescent cells accumulating in different tissues and organs, leading to aging and age-related disease susceptibility over time. Removing senescent cells from the body or slowing down the burden rate has been proposed as an efficient way to reduce age-dependent deterioration. In animal models, senotherapeutic molecules can extend life expectancy and lifespan by either senolytic or senomorphic activity. Much research shows that dietary and physical activity-driven lifestyle interventions protect against senescence. This narrative review aims to summarize the current knowledge on targeting senescent cells to reduce the risk of age-related disease in animal models and their translational potential for humans. We focused on studies that have examined the potential role of senotherapeutics in slowing the aging process and modifying age-related disease burdens. The review concludes with a general discussion of the mechanisms underlying this unique trajectory and its implications for future research.

Improving geriatric outcomes through nutritional and immunonutritional strategies: Focus on surgical setting by a comprehensive evidence review.

The aging population worldwide has led to an increased request for surgical interventions in older, geriatric, and frail patients. However, all the physiological changes related to aging are associated with many challenges in the perioperative period, strongly impacting surgical outcomes. Nutritional status plays a pivotal role in determining the resilience of older adults to surgical stress and their ability to recover postoperatively. It is well known that malnutrition, a prevalent concern in geriatrics, is linked to increased adverse outcomes, including morbidity and mortality. Recognizing the significance of preoperative nutritional screening, assessment, diagnosis, intervention, and monitoring is essential for optimizing surgical outcomes. In this context, immunonutrition, which involves the supplementation of specific nutrients to modulate immune responses, emerges as a promising strategy to mitigate the increased inflammatory response observed in geriatric surgical patients. This study reviews current literature on the impact of nutrition and immunonutrition on surgical outcomes in geriatrics, highlighting the potential benefits in terms of reduced complications, enhanced wound healing, and shortened hospital stays. Recognizing and addressing the specific nutritional needs of older persons undergoing surgery is essential for promoting successful surgical outcomes and improving overall quality of life in this vulnerable population.

Medication review and deprescribing in different healthcare settings: a position statement from an Italian scientific consortium.

Recent medical advancements have increased life expectancy, leading to a surge in patients affected by multiple chronic diseases and consequent polypharmacy, especially among older adults. This scenario increases the risk of drug interactions and adverse drug reactions, highlighting the need for medication review and deprescribing to reduce inappropriate medications and optimize therapeutic regimens, with the ultimate goal to improving patients' health and quality of life. This position statement from the Italian Scientific Consortium on medication review and deprescribing aims to describe key elements, strategies, tools, timing, and healthcare professionals to be involved, for the implementation of medication review and deprescribing in different healthcare settings (i.e., primary care, hospital, long-term care facilities, and palliative care). Challenges and potential solutions for the implementation of medication review and deprescribing are also discussed.

Efficacy of deprescribing on health outcomes: An umbrella review of systematic reviews with meta-analysis of randomized controlled trials.

BACKGROUND: Deprescribing is an important intervention across different settings in medicine, but the literature supporting such a practice is still conflicting. Therefore, we aimed to capture the breadth of outcomes reported and assess the strength of evidence of the use of deprescribing for health outcomes. METHODS: Umbrella review of systematic reviews of the use of deprescribing searching in Medline, Scopus, and Web of Science until 01 November 2023. The grading of evidence was carried out using the GRADE for intervention studies, whilst data regarding systematic reviews were reported as narrative findings. RESULTS: Among 456 papers, 12 systematic reviews (six with meta-analysis) for a total of 231 RCTs and 44,193 patients were included. In any setting, deprescribing was able to significantly reduce the number of total and of potentially inappropriate medications (PIMs) in older patients (low certainty of evidence) and to reduce the proportion of participants potentially having several or PIMs (moderate certainty of evidence). In community, supported by a high certainty of evidence, deprescribing was not more effective than standard care in decreasing injurious falls, any falls or number of fallers. In nursing home, deprescribing was associated with a significantly lower PIMs than standard care (very low certainty of evidence). In end-of-life situations, deprescribing significantly reduced mortality rate of approximately 41% (high certainty of evidence). CONCLUSIONS: Deprescribing is a promising intervention across different settings and situations, but a notable gap in the literature concerning its effects on substantial outcomes still exists.

Enriching Lives: Geriatricians' Mission of Supportive Care for Older Persons.

The growing older population, the increasing prevalence of chronic illnesses, and the pressing need to enhance the quality of end-of-life care have underscored the importance for geriatricians to focus on supportive and palliative measures. Within this context, the emphasis on delivering comprehensive and person-centered care has become crucial, ensuring that individuals not only receive medical treatment but also experience comfort during chronic illness and in their final days. Nevertheless, a significant number of older individuals often find themselves in hospitals during their last moments, sometimes undergoing aggressive medical interventions even when facing terminal conditions. The challenge lies in the early recognition of the end-of-life phase, initiating timely supportive and palliative care in conjunction with conventional treatments, adopting a multidisciplinary approach, and providing crucial support to grieving family members. Despite being a relatively recent field, geriatric palliative care (GPC) still requires further development. With this perspective, I aimed to shed light on the challenges and best practices for enhancing care for individuals facing chronic critical illnesses and frailty.

Exploring cerebral amyloid angiopathy: Insights into pathogenesis, diagnosis, and treatment.

Cerebral Amyloid Angiopathy (CAA) is a neurological disorder characterized by the deposition of amyloid plaques in the walls of cerebral blood vessels. This condition poses significant challenges in terms of understanding its underlying mechanisms, accurate diagnosis, and effective treatment strategies. This article aims to shed light on the complexities of CAA by providing insights into its pathogenesis, diagnosis, and treatment options. The pathogenesis of CAA involves the accumulation of amyloid beta (Aß) peptides in cerebral vessels, leading to vessel damage, impaired blood flow, and subsequent cognitive decline. Various genetic and environmental factors contribute to the development and progression of CAA, and understanding these factors is crucial for targeted interventions. Accurate diagnosis of CAA often requires advanced imaging techniques, such as magnetic resonance imaging (MRI) or positron emission tomography (PET) scans, to detect characteristic amyloid deposits in the brain. Early and accurate diagnosis enables appropriate management and intervention strategies. Treatment of CAA focuses on preventing further deposition of amyloid plaques, managing associated symptoms, and reducing the risk of complications such as cerebral hemorrhage. Currently, there are no disease-modifying therapies specifically approved for CAA. However, several experimental treatments targeting Aß clearance and anti-inflammatory approaches are being investigated in clinical trials, offering hope for future therapeutic advancements.

Diabetes-Alzheimer's connection in older age: SGLT2 inhibitors as promising modulators of disease pathways.

Late-onset Alzheimer's disease (LOAD) is the most frequent cause of dementia in older persons. Subjects affected by type 2 diabetes mellitus (T2DM) are at higher risk of vascular disease, cognitive decline, and dementia. LOAD has many characteristics shared with impaired insulin signaling pathways, and substantial evidence has demonstrated a pivotal role in dysregulated glucose metabolism in its pathogenesis. Recent studies have shown that some anti-diabetic drugs, other than regulating the metabolism of peripheral tissues, can also modulate the brain's metabolism, reduce inflammation, and have a direct neuroprotective effect. Sodium-glucose cotransporter-2 inhibitors (SGLT2i) are a newer class with many pleiotropic effects that may have strong neuroprotective potential. After a summary of the principal "anti-diabetic" drugs acting as suitable candidates in treating LOAD, this narrative review explored the potential role of SGLT2i on cognition from pre-clinical to clinical studies.

Polypharmacy and malnutrition in older people: A narrative review.

Polypharmacy is the simultaneous use of multiple medicines, usually more than five. Polypharmacy is highly prevalent among older individuals and is associated with several adverse health outcomes, including frailty. The role of polypharmacy in nutritional status seems to be crucial: although a clear association between polypharmacy and malnutrition has been widely reported in older people, the magnitude of the effect of increased number of drugs in combination with their type on the risk for malnutrition remains to be largely explored. Therefore, this review aims to discuss the association between polypharmacy and malnutrition in older people and to provide suggestions for its management. Polypharmacy is prevalent among malnourished frail patients, and the relative contribution of comorbidities and polypharmacy to malnutrition is difficult to be determined. Several mechanisms by which commonly used medications have the potential to affect nutritional status have been identified and described. Deprescribing (i.e., a systematic process of identification and discontinuation of drugs or a reduction of drug regimens) could be an essential step for minimizing the effects of polypharmacy on malnutrition. In this regard, the literature suggests that in older patients taking several medications, the best method to solve this problem is the comprehensive geriatric assessment, based on a holistic approach, including drug review, to find potential unnecessary and inappropriate medications. Nutritional and deprescribing interventions must be tailored to patient needs and to the local context to overcome barriers when applied in different settings.

A narrative review on mild behavioural impairment: an exploration into its scientific perspectives.

In clinical practice, the admission of patients with late-onset psychological and behavioural symptoms is frequent, regardless of the presence or absence of cognitive decline. These symptoms commonly occur in the prodromal stage of dementia and can precede the onset of dementia. While the concept of Mild Cognitive Impairment (MCI) -which is defined as a level of cognitive impairment insufficient to impact daily functioning- is well established, the notion of Mild Behavioural Impairment (MBI) is not yet widely recognized. However, studies have demonstrated that the presence of MBI in both cognitively normal patients and individuals with MCI is associated with an increased risk of dementia progression. Thus, MBI may serve as a neurobehavioral indicator of pre-dementia risk states. This narrative review aims to discuss the evolution of the term, the relevant clinical aspects, and potential biomarkers that may contribute to the clinical definition of MBI. The objective is to assist clinicians in recognizing the diagnosis and differentiating it from psychiatric syndromes, as well as identifying possible etiologies of neurodegeneration.

The Potential of Fasting-Mimicking Diet as a Preventive and Curative Strategy for Alzheimer's Disease.

This review examines the potential of fasting-mimicking diets (FMDs) in preventing and treating Alzheimer's disease (AD). FMDs are low-calorie diets that mimic the physiological and metabolic effects of fasting, including the activation of cellular stress response pathways and autophagy. Recent studies have shown that FMDs can reduce amyloid-beta accumulation, tau phosphorylation, and inflammation, as well as improve cognitive function in animal models of AD. Human studies have also reported improvements in AD biomarkers, cognitive functions, and subjective well-being measures following FMDs. However, the optimal duration and frequency of FMDs and their long-term safety and efficacy remain to be determined. Despite these uncertainties, FMDs hold promise as a non-pharmacological approach to AD prevention and treatment, and further research in this area is warranted.
