Hartford Foundation, American Geriatrics Society), Geriatric Emergency Department (GED) guidelines (EDE (emergency department for elders), protocols for falls, delirium, polypharmacy, functional decline, caregiver stress, palliative care)), Theories of Aging (biological—genetic (programmed longevity, telomere shortening, Hayflick limit (cells divide finite number of times), cellular senescence (senescence-associated secretory phenotype (SASP) (inflammatory cytokines, growth factors, proteases, contributes to aging, chronic disease)), stochastic (wear and tear, free radical (oxidative stress, mitochondrial damage, reactive oxygen species (ROS), antioxidant defenses decline with age), cross-linkage (advanced glycation end-products (AGEs) accumulate, collagen cross-linking, reduced elasticity (skin, blood vessels, lungs, tendons, ligaments), organ dysfunction), error catastrophe (errors in protein synthesis, accumulation of damaged proteins), immunological (immunosenescence (declining immune function, thymic involution, decreased T cell diversity, decreased B cell function, increased autoimmunity, increased susceptibility to infection (pneumonia, influenza, COVID-19, UTIs, skin infections), decreased vaccine response (higher dose influenza vaccine, adjuvanted vaccines, high-dose pneumococcal vaccine), increased cancer risk, increased autoimmune disease), neuroendocrine (hypothalamic-pituitary-adrenal (HPA) axis dysregulation, decreased growth hormone (GH), insulin-like growth factor-1 (IGF-1), dehydroepiandrosterone (DHEA), melatonin, estrogen, testosterone, increased cortisol)), psychosocial—disengagement theory (mutual withdrawal of older adult from society and society from older adult, natural, inevitable, universal, controversial, not supported by research), activity theory (successful aging requires maintaining activity levels, social engagement, roles, relationships, substituting lost roles with new ones, positive correlation with life satisfaction, health, cognitive function), continuity theory (personality, preferences, coping styles, activities persist throughout life, adapt to age-related changes by continuing familiar patterns, maintaining identity, self-esteem, life satisfaction), socioemotional selectivity theory (older adults prioritize emotionally meaningful relationships, narrow social networks, focus on present-oriented goals, emotion regulation, well-being), age stratification theory (society stratified by age, cohorts share historical experiences, age norms, age-linked roles and expectations, transitions (retirement, grandparenthood, widowhood, institutionalization)), person-environment fit theory (competence (physical, cognitive, functional abilities) interacts with environmental press (demands, supports), optimal adaptation when competence matches environmental demands (zone of maximum comfort (slightly lower demand than competence, comfort, autonomy, independence), zone of maximum performance (slightly higher demand than competence, challenge, growth, adaptation, may lead to stress if too high)), mismatch leads to stress, dysfunction, relocation stress (transfer trauma) (moving from home to facility, between facilities, may cause depression, anxiety, functional decline, increased mortality, interventions (pre-move preparation, familiar objects, family involvement, staff continuity, person-centered care)), successful aging models (Rowe & Kahn: avoidance of disease/disability, maintenance of high cognitive/physical function, active engagement with life (social, productive activities), Baltes: selective optimization with compensation (SOC) (select (prioritize goals, reduce less important activities), optimize (enhance resources, practice, training, technology), compensate (use alternative strategies, assistive devices, environmental modifications)), gerotranscendence (shift from materialistic, rational, social-conventional worldview to cosmic, transcendent, meditative, less fear of death, increased life satisfaction, wisdom, less interest in material possessions, social interactions, more contemplative, peaceful), common in oldest-old, not pathological, normal developmental stage), Age-Related Changes in Body Systems (cardiovascular—increased arterial stiffness (decreased compliance, increased pulse wave velocity, widened pulse pressure, isolated systolic hypertension (ISH)), left ventricular hypertrophy (increased afterload, decreased early diastolic filling, increased dependence on atrial contraction (atrial kick), loss of atrial kick in atrial fibrillation may cause significant decrease in cardiac output, heart failure, increased risk of atrial fibrillation (prevalence 10-20% in adults ≥80), decreased beta-adrenergic responsiveness (blunted heart rate response to exercise, stress, illness, use chronotropic incompetence (inability to achieve 85% of age-predicted maximum heart rate
