Mechanism of Saponins in Treating Alzheimer’s Disease
Drug development for Alzheimer’s disease, the leading cause of dementia, has been a long-standing challenge. Saponins, which are steroid or triterpenoid glycosides with various pharmacological activities, have displayed therapeutic potential in treating Alzheimer’s disease.

Nutritional Advice for Patients with Xerostomia
Xerostomia and hyposalivation are highly prevalent conditions in old age, particularly among multimorbid elders, and are often attributed to the use of multiple medications. These conditions negatively affect oral functions, such as chewing, swallowing, speech, and taste. Additionally, the lack of lubrication of the oral mucosa frequently leads to super-infections with candida.

Influencing Factors of Antibiotics Prescribing in the Elderly
Infections are important factors contributing to the morbidity and mortality among elderly patients. High rates of consumption of antimicrobial agents by the elderly may result in increased risk of toxic reactions, deteriorating functions of various organs and systems and leading to the prolongation of hospital stay, admission to the intensive care unit, disability, and lethal outcome. Both safety and efficacy of antibiotics are determined by the values of their plasma concentrations, widely affected by physiologic and pathologic age-related changes specific for the elderly population. Drug absorption, distribution, metabolism, and excretion are altered in different extents depending on functional and morphological changes in the cardiovascular system, gastrointestinal tract, liver, and kidneys. Water and fat content, skeletal muscle mass, nutritional status, use of concomitant drugs are other determinants of pharmacokinetics changes observed in the elderly. The choice of a proper dosing regimen is essential to provide effective and safe antibiotic therapy in terms of attainment of certain pharmacodynamic targets.

Relationship between Ferroptosis and Alzheimer’s Disease
Alzheimer’s disease (AD), which was first identified more than a century ago, has become a pandemic that exacts enormous social burden and economic tolls as no measure of combating devastated AD is currently available. Growing etiopathological, genetic, and biochemical data indicate that AD is a heterogeneous, polygenic, multifactorial, and complex disease. However, its exact etiopathology remains to be determined. Numerous experimental data show that cerebral iron and copper dyshomeostasis contribute to Aβ amyloidosis and tauopathy, two neuropathological hallmarks of AD. Increasing experimental evidence suggests ferroptosis, an iron-dependent and nonapoptotic form of cell death, may be involved in the neurodegenerative process in the AD brain. Thus, the anti-ferroptosis approach may be an efficacious therapeutic strategy for AD patients.

Brain Natriuretic Peptide in Geriatric Heart Failure Evaluation
Heart failure is one of the main morbidity and mortality factors in the general population and especially in elderly patients. Natriuretic peptides, in particular B-type natriuretic peptide (BNP) and its fraction NTproBNP, have gained an increasingly important role in the screening, diagnosis and treatment of heart failure.

Parkinson’s Disease, SARS-CoV-2 and Frailty
Literature has long established the association between aging and frailty, with emerging evidence pointing to a relationship between frailty and SARS-CoV-2 contagion. The possible neurological consequences of SARS-CoV-2 infection, associated with physical and cognitive frailty, could lead to a worsening of Parkinson’s disease (PD) in infected patients or—more rarely—to an increase in the Parkinsonian symptomatology. A possible link between those clinical pictures could be identified in vitamin D deficiency, while the whole process would appear to be associated with alterations in the microbiota–intestine–brain axis that fall within the α-Synuclein Origin site and Connectome (SOC) model, and allow for the identification of a body-first PD and a brain-first PD. The model of care for this condition must consider intrinsic and extrinsic variables so that care by a multidisciplinary team can be successfully predicted.

Tumor Necrosis Factor Antagonists in Neuroinflammation for Dementia
Prolonged activation of pro-inflammatory responses in Alzheimer’s disease (AD) alters function of glial cells and in turn, further accelerates neuroinflammation. Subsequent synaptic dysfunction and loss of neurons are responsible for clinical symptoms of the disease. Additionally, factors such as insufficient sleep length and subsequent reduction in amyloid clearance via the glymphatic system lead to amyloid accumulation, while simultaneously aggravating systemic inflammatory response. Inflammation in vascular dementia (VaD) contributes to the three-hit hypothesis, along with hypertension and hypoxia. Vasculitis is responsible for restricted blood circulation in microvessels and leads to decreased oxygen supply and regional glial activation favoring neuroinflammation in the central nervous system (CNS). Peripheral immune response and increased cytokine production, including an early surge in TNF and IL-1β concentrations activate glia, leading to aggravation of neuroinflammation and dysfunction of neurons during COVID-19. Lifestyle factors, such as diet, have a large impact on future cognitive outcomes and should be included as a crucial intervention in dementia prevention.

Cannabinoid Systems and the Brain
The use of cannabinoids as therapeutic drugs has increased among aging populations. Age-related changes in the endogenous cannabinoid system could influence the effects of therapies that target the cannabinoid system. At the preclinical level, cannabidiol (CBD) induces anti-amyloidogenic, antioxidative, anti-apoptotic, anti-inflammatory, and neuroprotective effects. These findings suggest a potential therapeutic role of cannabinoids to neurodegenerative disorders such as Parkinson’s disease (PD) and Alzheimer.

Effects of Multimorbidity and Frailty on Diabetes
Multimorbidity and frailty are highly prevalent in older people with diabetes. This high prevalence is likely due to a combination of ageing and diabetes-related complications and other diabetes-associated comorbidities. Both multimorbidity and frailty are associated with a wide range of adverse outcomes in older people with diabetes, which are proportionally related to the number of morbidities and to the severity of frailty.

CDGSH Iron-Sulfur Domain 2 Mediates Lifespan and Healthspan
An age-dependent decrease in CDGSH (Cys-Asp-Gly-Ser-His) iron-sulfur domain 2 (CISD2) expression during the natural aging of mice has been reported in a range of tissues, including the brain, spinal cord, skeletal muscle, heart, and skin. However, the rate of CISD2 downregulation varies from tissue to tissue.
