Telomeres and Telomerase?
Telomerase is the natural enzyme which promotes telomere repair. It is however not active in most cells. It certainly is active though in stem cells, germ cells, hair follicles and in 90 percent of cancer cells. Telomerase functions by adding bases to the ends of the telomeres. As a result of this telomerase activity, these cells seem to possess a kind of immortality.

Tissues look normal, patches of faulty gene expression – aquired epigenetic changes

Obstetrical Outcome Research Needed the Apgar Score
Adult scoring systemsIntensive Care Assessment
These scoring systems can be used on patients age 15 and up.•APACHE II was designed to provide a morbidity score for a patient. It is useful to decide what kind of treatment or medicine is given. Methods exist to derive a predicted mortality from this score, but these methods are not too well defined and rather imprecise. •SAPS II was designed to provide a predicted mortality, that does not reflect the expected mortality for a particular patient, but is good for benchmarking. In a rather simple way, it makes it possible to provide a single number that describes the morbidity of a number of patients. •SAPS III was designed to provide a realistic predicted mortality for a particular patient or a particular group of patients. It does this by calibrating against known mortalities on an existing set of patients, for a specific definition of mortality (like 30-days mortality). This way, it can answer questions like "Did we improve our quality of care from 2004 to 2005?" or "If hospital A's patients had been treated at hospital B, would they have a better or a worse mortality?".

• 2 for normal ADL & Social Function
• 2 for normal Cognition (Clock Test)
• 2 for normal Muscle Strength (Hand Grip)
• 2 for normal Age adjusted Blood, Liver, Lung and Kidney Function (simple screen)
• 1 for no severe chronic disease
• 1 for not requiring acute treatment
Clinical Trials in the Elderly
• Ageism or Bias against trial entry• Better cancer classification
(chromosomes, genetics, proteomics)• Improved pharmacology, predictable
toxicity, efficacy and cost of treatment• Stratification Score for Population Studies• Specialized Assessment Instruments –
toxicity, physical and social function, and satisfaction

Importance of Comorbid Conditions (cont.)
• Increase with age
• Resilience (covert comorbidity) to toxic treatments decreases with age
• Overt comorbidity affects treatment selection
• May hamper patient recovery

Financial Barriers for Elderly with Active Cancer Care
• No Drug Benefit
• Diagnostic Procedures – 20% Co-payment
• Out of Pocket Costs– Transportation (+ Income Loss For Drivers)– Role Reversal (Others to care for Spouse)– Hospital Deductible Payments
• Adjuvant Therapies (Tamoxifen, Growth Factors, Pain Medications)
Cost of Care of the Elderly
• About 30% of Medicare Budget Spent on 5% of Patients Destined to Die in that Year*
• 30-40% of last year of health care costs occur in the last month of life*
• Better methods of Defining Medical Futility would eliminate some Expenditures.
* Emanuel EJ & Battin MP. N Engl. J.Med.1998;339:167-172
Contributing Factors
• Equipment Costs –e.g., MRI, Spiral CT• Supply Costs – Plastics tied to Oil Prices• Nurses Salaries – Shortage likely to
persist– Salary Differential in Specialties – ICU, NP
• Information Systems – Privacy Costs• Managing High Risk Populations
Budget Rationing of Care
• At the Present Spending Level an Increase to 30% of G.N.P. by 2030
UNLESS THERE IS:
• Increased Personal Costs– Directly - through higher deductibles– Indirectly – through care shifting to families
• Shrinking Coverage based on Age• Dual System – Wealthy versus the Poor

Future Research Directions
• Molecular Targets for Diagnosis, Prognosis & Treatment
• Incentives for Drug & Biologic Development• Coping with an Aging Population- Research
– Stratification Score– Early Detection– Managing Comorbidity– Palliative Care
• Ethical Dilemmas-Privacy, Profits, Rationed Care
Future Practical Changes• Will Need Public (Academic) –Private Alliances to Develop the
leads from Genetic Research• Develop New Markers for Early Diagnosis, Prognosis &
Treatment Selection• Methods to Stratify the Elderly to Facilitate the Adoption of
Guidelines • Tie Reimbursement to Quality Assurance• Models for Reimbursement Reform for Chronic Disease
Management – Cognitive Skills & Time – Remove Distorted Incentives for Providing
Technical Procedures – Innovative Assisted Living Arrangements– Team Care Including the Elderly and their Families
Geriatrics and OncologyToday’s Needs
• Bilateral Training (Oncologists & Geriatricians)• Research on Aging and Cancer
– Cancer Biology (e.g. Breast and Prostate)– Falls, Cognitive Diminution, Incontinence & Sexual Function– Clinical Trials
• Data on Cost and Efficacy of Screening and Early Detection
• Social Support (Income, Transportation, Home Care, Who?)
• Optimal Environment ( Hazards, Exercise, Nutrition, Rx Care)
• Reimbursement (interdisciplinary management)
