Study Notes

Geriatrics: Defining Old Age

The perceived onset of old age has been increasing by roughly one year every four to five years of actual aging.
The average life expectancy at age 65 for men is 17 years (age 83), while for women it is 19.7 years (age 85).
By 2050, the global population over 60 will have nearly doubled, from 12% to 22%.

Impact of Aging on Healthcare

Patients aged 65+ account for a significant portion of healthcare workloads, including 35% of surgical care, 37-60% of ER visits, 43% of medical specialty care, and 35% of inpatient hospital days.
Aging presents challenges related to finance, medical resources, and ethical considerations, such as end-of-life care and resource allocation.

Theories of Aging

Aging can be categorized as either programmed or caused by error and damage.
Programmed Theories:
- Immunologic Theory: Suggests that the immune system naturally declines with age, leading to increased susceptibility to disease.
- Programmed Longevity: Aging is a pre-programmed biological process with genetic influences.
- Endocrine Theory: Aging involves changes in hormonal production, affecting various bodily functions.
Error or Damage Theories:
- Wear and Tear Theory: Aging is due to the cumulative damage inflicted by daily wear and tear on cells and tissues.
- Rate of Living Theory: Life expectancy is directly proportional to metabolic rate, with faster metabolisms leading to shorter lifespans.
- Free Radicals: Oxidative stress caused by unstable molecules can damage cells and contribute to aging.
- Somatic DNA Mutations: Accumulation of DNA mutations in somatic cells can disrupt normal cell function and contribute to aging.

Aging Concept 1: Heterogeneity of Aging

Age alone is not a reliable indicator of an individual's physical condition or behaviors.
Focusing on individualized needs and assessments rather than simply age is crucial.

Lifestyle Factors and Blue Zones

Usual Aging: Refers to the common pattern of decline associated with aging.
Successful Aging: Characterized by minimal age-related decline, often achieved through healthy lifestyle choices.
Blue Zones: Geographical regions with clusters of long-lived individuals.
Key Lifestyle Factors in Blue Zones:
- Plant-based diet with minimal meat consumption.
- Calorie restriction or fasting.
- Moderate alcohol consumption, primarily red wine rich in antioxidants.
- Strong sense of purpose in life.
- Daily physical activity, including gardening, walking, and household chores.
- Stress management through activities like prayer, meditation, or spending time with family.
- Central role of faith.
- Strong family structures with intergenerational relationships.
- Supportive social networks promoting healthy lifestyles.

Aging Concept 2: Homeostenosis

Homeostasis: The body's natural ability to maintain equilibrium.
Homeostenosis: The gradual decline in physiological reserves with aging, reducing the body's ability to maintain homeostasis.

Aging Concept 3: Aging is Not a Disease

The risk of developing chronic diseases increases with age.
Differentiating between normal aging and disease is crucial for appropriate medical intervention.
The "rule of 1/4ths" suggests that 1/4 of decline attributed to aging is due to actual physiological aging, while the rest is attributed to disease, disuse, and misuse.

Cardiovascular Changes with Aging

Atherosclerosis: Hardening of arteries, increasing afterload and leading to left ventricular hypertrophy.
Myocardial Stiffness & Diastolic Dysfunction: Increased left ventricular wall thickness with age leads to stiffness and impaired diastolic function.
Impaired Myocyte Calcium Handling: Decreased contractility due to reduced calcium handling in heart muscle cells.
Decreased β-Receptor Sensitivity: Reduced sensitivity to beta-adrenergic stimulation affects heart rate and response to medication.
Decreased Vagal Tone: Leads to a decrease in intrinsic heart rate.
Aortic Valve and Mitral Annulus Calcification: May cause heart murmurs despite normal valve function, altering blood flow patterns.
Loss of Pacemaker Cells and Fatty Deposits: Increased risk of arrhythmias.
Arterial Atherosclerosis: Modest increase in systolic blood pressure.
Orthostatic Hypotension: A common consequence of decreased β-receptor sensitivity and other age-related changes.

Clinical Implications of Cardiovascular Changes

Orthostatic Hypotension: Susceptibility to drops in blood pressure upon standing.
Sensitivity to Diuretic Effects: Increased sensitivity to the hypotensive effects of diuretics.
Elevated Systolic Blood Pressure: Modest increase in systolic blood pressure.
Low Pulse Rates: Slower heart rate.
Reflex Tachycardia: Increased heart rate in response to stimuli.
High Prevalence of Atrial Arrhythmias: Increased likelihood of atrial fibrillation and other arrhythmias.
Limited Efficacy of Vasodilators: Direct-acting vasodilators may be less effective.

Vital Signs & Aging

Blood Pressure: Systolic and diastolic blood pressure may increase with age due to arterial stiffening.
Temperature: Age-related changes can impact temperature regulation, increasing the risk of hypothermia.

Respiratory Changes with Aging

Decreased Exercise Capacity: Reduced vital capacity, forced expiratory volume, and chest wall compliance lead to decreased exercise capacity.
Decreased Surface Area for Gas Exchange: Reduction in functional alveoli leads to impaired gas exchange and shortness of breath.
Increased Risk of Pneumonia: Reduced cilia activity, diminished cough strength, and less effective lung macrophages increase the risk of pneumonia.

Renal Changes with Aging

Decreased Creatinine Clearance: Reduced kidney size and number of glomeruli result in decreased creatinine clearance.
Decreased Ability to Concentrate Urine: Reduced renal tubule cells and thickened tubular walls impair urine concentration.
Increased Risk of Dehydration: Blunted thirst, decreased serum renin, and aldosterone increase susceptibility to dehydration.

Gastrointestinal Changes with Aging

Gastritis: Reduced gastric cell count and increased post-prandial gastric pH contribute to gastritis.
Risk of Aspiration: Less effective chewing and impaired swallowing coordination increase the risk of aspiration.
Constipation: Decreased peristalsis and smooth muscle tone can lead to constipation.
Reduced Liver Efficiency: Decreased liver size and blood flow reduce the liver's ability to metabolize drugs and toxins.
Increased Post-Prandial Glucose Levels: Decreased insulin release from the pancreas can result in higher blood sugar levels after meals.

Hematologic Changes with Aging

Delayed Recovery of Blood Counts: Decreased bone marrow mass and increased bone marrow fat lead to delayed recovery of blood counts following stress, such as bleeding or hypoxia.
Increased Risk of Venous Thromboembolism (VTE): Increased hypercoagulability raises the risk of blood clots.

Immune System Changes with Aging

Immunosenescence: Age-related decline in immune function.
Increased Risk of Infections and Malignancy: Weakened immune system increases susceptibility to infections and cancer.
Reduced Vaccine Responsiveness: Immune system response to vaccines may be less effective.
