ANSWERS 2024/
How to conduct Mini-Cog-
- The Mini-Cog has been demonstrated to have comparable psychometric properties to the MMSE
- The primary advantage of the Mini-Cog is that it is shorter than the MMSE and measures executive function.
- It is composed of a three-item recall and the Clock Drawing Test (CDT) and takes about 3 minutes to administer
- The Mini-Cog is a short dementia assessment that combines three-word recall with clock-drawing capability.
- Patients are given a total score reflecting accuracy in clock drawing and recollection of the given three words.
- A score of 0 to 2 is a positive screen for dementia Causes of delirium in elderly-
- Causes of delirium are numerous and in elderly hospitalized patients there are often multiple etiologies, including metabolic, infection, cardiac, neurological, pulmonary, sensory impairments, medications, and toxins.
- Regardless of cause, a consistent finding is significant reduction in regional cerebral perfusion during periods of delirium in comparison with blood flow patterns after recovery.
- A possible neurological common pathway may involve acetylcholine and dopamine, and the disruption in the sleep-wake cycle in delirium indicates melatonin as a possible factor. (Kennedy-Malone 59) Agnosia
- Loss of ability to identify objects ADA criteria for diagnosing DM-
- FPG ≥126 mg/dL (7.0 mmol/L). Fasting is defined as no caloric intake for at least 8 h.*
- 2 - h PG ≥200 mg/dL (11.1 mmol/L) during OGTT. The test should be performed as described by the WHO, using a glucose load containing the equivalent of 75 - g anhydrous glucose dissolved in water.*
- A1C ≥6.5% (48 mmol/mol). The test should be performed in a laboratory using a method that is NGSP certified and standardized to the DCCT assay.*

- Kennedy p 567- 568 Sexuality sundowning metformin side effects-
- GI side effects take with supper. Most patients adjust to these SE. ADVERSE effect- Lactic acidosis. B deficiency
- Biguanides (Metformin) has become a cornerstone of drug treatment for type 2 disease, based on its proven efficacy not only in controlling glucose intolerance but also in significantly reducing risk of important macro- and microvascular outcomes, especially in overweight and obese patients (as found in the UKPDS study referred to earlier and below). In glycemic treatment algorithms for type 2 disease, initiation of metformin is recommended at the time of diagnosis along with diet and exercise.
- Mechanism of Action. Metformin differs from the traditional oral hypoglycemics (i.e., the sulfonylureas) in that it does not stimulate endogenous insulin secretion; rather, drugs of this class enhance tissue responsiveness to insulin. Consequently, biguanides are less likely to induce hypoglycemia and are particularly effective in the treatment of overweight patients with tissue resistance to insulin. Biguanides facilitate insulin uptake by
peripheral tissue, especially muscle and liver, and decrease hepatic gluconeogenesis and basal glucose output, thereby helping to lower fasting glucose levels. Glucose utilization also improves in adipose and intestinal tissues. The net result is an improvement in fasting and postprandial hyperglycemia. Insulin demand declines as glucose utilization improves. Serum lipid abnormalities also improve.
- Preparations. Metformin is the only biguanide approved in the United States for the treatment of type 2 diabetes. The drug is rapidly and well-absorbed in the small intestine, with peak plasma concentrations in 2 hours. It is rapidly excreted unchanged by the kidneys. Impaired renal function (creatinine >1.5 mg/dL in men and >1. mg/dL in women) is a contraindication for use, especially at full doses. The drug is not metabolized by the liver. The original biguanide, phenformin, is no longer marketed because of its associated risk for lactic acidosis and an excess cardiovascular mortality (see later discussion).
- Dosing. The starting dose of metformin is 500 mg once daily with dinner. After 1 week, the dose is increased to twice daily, given with the two largest meals of the day (usually breakfast and dinner) to minimize gastrointestinal upset. The dose can be increased by 500 mg every 1 to 2 weeks until treatment goals are met or the maximum dose of 2,000 to 2,500 mg/d is reached. An extended-release formulation is also available, which can help to improve compliance.
- Efficacy. When used as monotherapy in an obese person with moderate glucose intolerance, metformin’s efficacy in terms of glycemic control (i.e., lowering fasting glucose and glycosylated hemoglobin levels) is about the same as that of a second-generation sulfonylurea. Incidence of monotherapy treatment failure is less for metformin than for glyburide (21% vs. 34% at 5 years). A synergistic effect is achieved when combined with sulfonylurea therapy in patients who do not respond well to metformin alone. Unlike the sulfonylureas, metformin is effective even in severe fasting hyperglycemia (>300 mg/dL), indicative of poor beta-cell responsiveness. Plasma triglycerides and LDL cholesterol levels are decreased. In the UKPDS trial noted earlier, obese patients (>120% of ideal weight) with type 2 diabetes treated with metformin and attaining target glycemic control achieved clinically important, statistically significant, sustained long-term reductions in risks of microvascular disease and macrovascular complications (i.e., myocardial infarction, stroke, and cardiovascular death); all-cause mortality was also significantly reduced. These findings make metformin one of the few antihyperglycemic drugs with demonstrated ability to reduce macrovascular risk, the holy grail of diabetes management.
- Adverse Effects. The most common side effect of biguanide therapy is dose-related gastrointestinal upset ( nausea, diarrhea, bloating, abdominal discomfort ). The risk for serious prolonged hypoglycemia is minimal. Lactic acidosis represents the most potentially serious adverse effect. One of the original biguanides— phenformin—was taken off the market by the U.S. Food and Drug Administration (FDA) in 1977 because of its association with fatal episodes of lactic acidosis. The risk for lactic acidosis associated with metformin is greatest in the setting of hypoxemia, hypovolemia, and states with decreased tissue perfusion and in renal insufficiency (creatinine >1.5 mg/dL). Accumulation of the drug secondary to reduced excretion results in impaired hepatic metabolism of lactate. Other risk factors include binge drinking, use of intravenous radiologic contrast agents, hepatic failure (lactate is metabolized by the liver), and serious underlying illness, particularly heart failure.Long- term data on safety have yet to be accumulated. Because insulin secretion is not increased with metformin use, weight gain does not occur; some patients may even lose weight. Patients who are to undergo a radiologic procedure that requires intravenous iodinated contrast should have their metformin therapy held for a few days prior to the procedure and remain well hydrated.
- Patient Selection. Based on the landmark results of the UKPDS, obese patients should be considered especially good candidates for metformin therapy. The drug helps to reverse their insulin resistance, peripheral responsiveness to insulin improves, and insulin needs decrease, so hyperinsulinism and its adverse effects, including weight gain, are minimized. The typical candidate is a moderately obese person with type 2 diabetes who has persistent moderate hyperglycemia (fasting glucose between 140 and 240 mg/dL, glycosylated hemoglobin >7.0%) despite a full program of diet and exercise. Early addition of metformin is suggested. Other candidates for metformin include obese patients who do not achieve tight control while taking a sulfonylurea at maximal doses. In this setting, metformin is added to the oral hypoglycemic program to improve control through its complementary mode of action. The sulfonylurea dose is reduced to lessen the risk for hypoglycemia. Combination therapy is most effective when initiated before the onset of symptomatic hyperglycemia (fasting glucose >250 mg/dL). Nonobese patients are also reasonable candidates for metformin. Typically, metformin lowers fasting blood glucose by approximately 20%.Patients who started drug therapy with a sulfonylurea and become unresponsive to maximal doses have likely exhausted their beta-cell reserve and can be switched to metformin or considered for exogenous insulin therapy (sometimes in conjunction with metformin). The same
pertains to the severely hyperglycemic obese patient (fasting glucose >300 mg/dL). Some diabetologists use metformin to supplement an insulin program in obese type 2 diabetics who require large insulin doses and have difficulty losing weight. The combined program helps to reduce insulin requirements and the appetite stimulation and weight gain that accompany hyperinsulinism. Caution and careful patient monitoring are required when a patient taking exogenous insulin is started on metformin; the insulin requirement may drop considerably, putting the patient at risk for hypoglycemia.

- BMD measurement is expressed as the number of standard deviations from the mean for normal young adults of the same sex ( T-score ) and as the number of standard deviations from the mean for persons of the same sex and age ( Z score ).
- The World Health Organization diagnostic criterion for osteoporosis is a T-score of less than - 2.5. Osteopenia is defined as a T-score between - 1.0 and - 2.5. A Z score of less than - 1.5 suggests a secondary cause of osteoporosis
- Osteoporosis: - 2.5 or lower
- Osteopenia: - 1 to - 2.5 (lower than normal bone density w/o full osteoporosis) Anxiety treatment-
- Treatment for anxiety should reduce symptoms and improve functioning.
- Simply listening, being compassionate, and showing respect are important to improving outcomes. Treat comorbid depression and medical conditions that cause anxiety.
- There are no large-scale studies of pharmacotherapy for late-life anxiety disorders to guide treatment decisions.
- Start low and go slow with medication dosing to avoid risks from drug interactions, because older adults are more likely to take many medications and may have side effects from aging changes in absorption, metabolism, distribution, and excretion of medication.
- Evaluate and manage side effects, because as many as 25% of patients stop taking medication in the first 6 months due to side effects.
- First-line treatment is the selective serotonin reuptake inhibitors (SSRIs) o citalopram (Celexa), escitalopram (Lexapro), and sertraline (Zoloft). In older adults, they have the least risk of drug interactions, side effects, or worsening existing medical conditions. o Benzodiazepines, including lorazepam (Ativan), alprazolam (Xanax), and clonazepam (Klonopin), are effective according to research but are not the first choice due to the risk of falls and confusion. Research supports referral to psychotherapy for older adults, but this recommendation is limited to GAD and no other anxiety disorders (American Psychiatric Association, n.d.; Cassidy & Rector, 2008; Hollander & Simeon, 2008; Lenze et al., 2005; Lenze & Wetherell, 2009; Mohlman, 2005; National Institute of Mental Health, n.d.; Stanley et al., 2003; Wetherell, Lenze, & Stanley, 2005; Wetherell, Sorrell, Thorp, & Patterson, 2005).

Week 1 video & lesson notes (taken directly from videos- refer to lesson videos for sources):
- Leading causes of death in Older Adults > 65 y/o: Heart disease, cancer, and chronic lower respiratory
disease
- Ask older adults specifically about chronic pain; they may not volunteer the info.
- Chronic pain is not a normal effect of aging.
- Functional assessment, pain assessment, and med review on all patients- especially elderly
- COPD is the #1 cause of chronic morbidity & mortality worldwide & the 3rd^ leading cause of US death
- COPD risk factors- smoking; occupational & environmental exposures; severe childhood lung infections;
GERD, TB, low socioeconomic status
- Alpha- 1 antitrypsin deficiency- extremely rare COPD cause; mostly of northern European heritage.
- GOLD criteria- consider COPD in anyone with dyspnea, chronic cough or sputum production or above risks
- COPD- expiratory labor
- COPD PE: WNL early on then lung hyperinflation, decreased BS, basilar wheezing, distant S1S2 r/t
hyperinflation; cyanosis, clubbing, pursed lip breathing, accessory muscles, posturing (lean forward), JVD
- CAT- 8 items; measure COPD health status impairment
- CPQ- clinical COPD questionnaire; self-administered; measure clinical control of patients with COPD
- MMRC questionnaire (Modified British Medical Research Council) breathlessness measurement- relates to
other health measures & predicts mortality risk for COPDer
- CAT, CPQ, MMRC are all adapted from GOLD guidelines
- Spirometry is the gold standard for diagnosing COPD – do on anyone with s/s > 40 years old- showing
persistent airflow limitation
- Diagnostic aids: CXR, ABG, Alpha-1 angiotrypsin level, high-resolution chest CT, lung volumes and diffusing
capacity, pulse ox, exercise testing, and composite scores
- Stage & severity of COPD based on spirometry pre-& post bronchodilator
- COPD mgt goals: 1. Id. disease severity (airflow limitation) 2. Id. Health impact of COPD 3. Future event risk
GOLD COPD stage Spirometry classification (2014)
Stage FEV1:FVC FEV
Mild <0.70 > or = 80% of predicted value
Moderate <0.70 50 - 79% of predicted value
Severe <0.70 30 - 49% of predicted value
Very severe <0.70 <^ 30%^ of^ predicted value^ OR^ <^ 50%^ of^ predicted value^ with^ chronic respiratory

Pulmonary Differential Diagnoses for COPD/ other:
Asthma, Bronchogenic carcinoma, Bronchiectasis, TB, CF, Interstitial lung disease, Bronchiolitis obliterans,
Alpha-1 antitrypsin deficiency, Pleural effusion, Pulmonary edema, Recurrent aspiration,
Tracheobronchomalacia, Recurrent pulmonary emboli, foreign body
Non-Pulmonary Differential Diagnoses for COPD/ other:
HF, hyperventilation syndrome/ panic attacks, vocal cord dysfunction, undx OSA, Aspergillosis, chronic fatigue
syndrome
Med management of COPD:
1. Bronchodilators – don’t slow COPD progression; do increase airflow, decreased WOB, Imp. exercise tol.
2. Bronchodilators
a. Beta 2 agonists (LABA, SABA)
i. MOA- Stimulate Beta2 adrenergic receptors, increasing cyclic AMP & relaxing airway smooth
muscle
ii. Adverse effects- tachycardia, palpitations, tremors, cramping, insomnia, hypokalemia, prolonged
QT, interval hyperglycemia
iii. levalbuterol no advantage over albuterol (per her; in real life levalbuterol has less cardiac effects)
b. Anticholinergic aka antimuscarinic (long-acting , short-acting )
i. MOA- blocks effect of acetylcholine on muscarinic-type 3 receptors; thus, bronchodilation
ii. dry mouth and constipation
c. Combinations – slightly increased bronchodilation than either agent alone
d. Oral bronchodilator- Theophylline- use if symptoms with inhalers or can’t afford inhalers
i. Concerns re: toxicity (elderly – hallucination, tachycardia, liver disease, HF) & drug interactions
(CYP 1A2, CYP 3A4)
ii. Therapeutic range (5- 12 mcg/mL)
iii. Use slow-release (generic available)
3. Oral corticosteroids
a. Poor predictor of long-term response to inhaled steroids in COPD
b. Long-term po steroids not recommended for stable COPD. Add inhaled steroids to inh bronchodilators
with severe COPD or frequent exacerbation.
c. Improve exacerbation frequency, QOL, hospitalization rates- doesn’t slow COPD progression
d. Need to use with a LABA for COPD patients
4. Inhaled corticosteroids (ICS)
a. ICS monotherapy is only FDA approved for treatment of asthma, not COPD
b. Adverse reaction- candidiasis and dysphonia – RINSE after use
c. Systemic absorption with high doses (1,000 mcg/d)- bruising, cataracts, reduced bone mineral density.
d. Increased pneumonia risk & LABA+ICS no real improvement in exacerbation frequency
e. Save ICS for severe COPD - FEV1 of less than 50% predicted
5. Improve spirometry use, Vaccinations (pneumaVAX <55 if smoker/ 65+ if non-smoker), Pulmonary
rehabilitation, COPD registry, quit smoking, diet/exercise

Spirometry measures:
Flow loops indicate validity of results, but flow loops WILL NOT be on boards or tests – just included
them because they help make sense of the changes in values
Spirometry- tech enters age, weight, race, sex & height - when looking at results you don’t need this- it’s pre-
calculated in the results
Spirometry Results and GOLD classifications:
Normal values GOLD classifications post bronchodilator
FEV 1 (step 2 grade severity)
FEV 1 80% to 120% GOLD 1 mild FEV1 > = 80% predicted
GOLD 2 moderate FEV1 50% to 79%
predicted
GOLD 3 severe FEV1 30% to 49% predicted
GOLD 4 Very severe FEV1 < 30% predicted
FVC 80% to 120%
FEV1/FVC ratio
(step 1 = determine if
obstruction)
> 70% (no
obstruction)
Step 3 - Reversibility?
A. Test spirometry pre and post bronchodilator (SABA or SAMA)
B. Post testing is 10 - 15 minutes after SABA/SAMA
C. ATS criteria: “significant response” is > = 12% FEV1 or FVC improvement and an absolute improvement
of > = 0.2 L
D. : “significant response” indicates asthma (due to reversibility)
Interpreting PFT results
Step 1: Check the ratio to see if obstruction exists. Is FEV1/FVC low? <70 = Obstructive defect or COPD
Step 2: grade severity with FEV1 post bronchodilation to classify by GOLD criteria
GOLD 1 mild FEV1 > = 80% predicted
GOLD 2 moderate FEV1 50% to 79% predicted
GOLD 3 severe FEV1 30% to 49% predicted
GOLD 4 Very severe FEV1 < 30% predicted
Step 3 - Reversibility Is there a 12% FEV1 or FVC increase post bronchodilation? Yes = reversible
TYPICAL PNEUMONIA SYNDROME - (see lesson;Hutt & Kramer, 2002; Furman, Rayner, & Tobin, 2004):
Fast fever, cough = new/worse; purulent sputum (rusty, green), pleuritic CP; Lobar infiltrate on chest X-ray
(day 2+ - may become infiltrates) indicating pulm consolidation; Consider Streptococcus pneumoniae & other
bacterial pathogens
ATYPICAL PNEUMONIA - (see lesson; Hutt & Kramer, 2002; Furman, Rayner, & Tobin, 2004):
Gradual fever, dry cough, min secretions, HA, malaise, myalgias, pharyngitis, GI distress. crackles (rales);
Abnormal or patchy chest X-ray pattern. Consider mycoplasma or chlamydia, pneumoniae, or oral anerobes.
Viral pneumonia may be atypical in presentation.

Week 2 notes: BPH and BP: Alpha blockers include doxazosin mesylate (Cardura), prazosin hydrochloride (Minipress), and terazosin hydrochloride (Hytrin); If we start on alpha blocker, they should follow up in 4 - 6 weeks. PROSCAR (finasteride): inhibitor of steroid Type II 5α-reductase, an intracellular enzyme that converts the androgen testosterone into 5α- dihydrotestosterone (DHT). For BPH & male pattern baldness.
Week 1 Topics NR 601: Week 2 Quiz Review by Alizabeth Anne Madison
- Aging (Chapter 1) Chapter 1: Changes with Aging - Notes Fundamental Considerations
- Recognize that presenting features of disease/illness may be different and having a greater awareness of the impact of chronic illness on the patient.
- Perspective is different than with younger adults. Physiological Changes with Aging
- The clinician must be aware that all the systems interact an, in doing so, can increase the older person’s vulnerability to illness/disease.
- During the clinical decision-making process, the clinician knowledgeable about physiological changes with aging will be less likely to undertreat a treatable condition. - Example- Use the diagnostic process to differentiate the more benign seborrheic keratosis from actinic keratosis.
- Be informed; do not attribute a finding to the aging process alone. The elder may conclude there is no point in changing behavior, because the process is inevitable. - Three primary points:
- There is a reduced physiological reserve of most body systems, particularly cardiac, respiratory, and renal.
- There are reduced homeostatic mechanisms that fail to adjust regulatory systems such as temperature control and fluid and electrolyte balance.
- There is impaired immunological function: infection risk is greater, and autoimmune diseases are more prevalent. other (anemia or UTI) and overdiagnosis and overtreatment in others (hyperglycemia or asymptomatic bacteriuria).
- At times, the result of a lab value may be within the appropriate reference range yet indicate pathology for the older adult.
- Calculation of creatinine clearance is important in the estimation of renal function.
- Reduced renal function, particularly GFR, affects clearance of many drugs, and creat clearance provides an index of renal function for use in choosing doses of renally eliminated or nephrotoxic drugs (such as dig, H2 blocker, lithium, and water soluble antibiotics)
- The Modiciation of Diet in Renal Disease (MDRD) and Cockcroft-Gault equations both provide useful estimates of the GFR.
- Any risks involved in lab testing must be considered with respect to the patient’s clinical condition and weighed against the test’s expected benefits. Pharmacokinetic & Pharmacodynamic Changes
- Polypharmacy and the potential for an adverse drug reaction (ADR) are major concerns in elders.
- Polypharmacy primary predictor for an ADR (any unwanted response).
- The therapeutic window narrows with age. The potential for benefiting the patient measured against risk of doing harm important.
- Pharmacokinetics (what the body does to the drug) and pharmacodynamics (what the drug does to the body) alter the dynamic processes that drugs undergo to produce therapeutic effect due to the effects of the aging process. Laboratory Values in Older Adults
- Many factors can influence lab value interpretation in the elderly, including the physiological changes with aging, the prevalence of chronic disease, changes in nutritional and fluid intake, lifestyle (including activity), and the medications taken.
- Reference ranges therefore may be preferable. Reference ranges or intervals, such as age, sex, or race can be defined demographically. For example, the reference range for older adults might be the intervals within which 95% of persons over age 70 fall.
- Further defined physiologically (fasting or activity status) or pharmacologically (medication, tobacco or ETOH use).
- Biochemical individuality is of particular importance in detecting asymptomatic abnormalities in older adults. Significant homeostatic disturbances in the same individual may be detected through serial laboratory tests, even though all individual test results may lie within normal limits of the reference interval for the entire group.
- The clinician must determine whether a value obtained reflects a normal aging change, a disease, or the potential for disease.
- Misinterpretation of an abnormal lab value as an aging change can lead to underdiagnosis and undertreatment in Absorption
- Less impact than distribution, metabolism, elimination.
- Gastric acidity declines with age; offset by the longer contact time that occurs as transit time slows – which is more functional than physiological.
- Presence of food and other drugs in the stomach at the same time affect drug absorption.
- Antacids and Fe can inhibit absorption.
- Anticholinergic meds cause a slowing of colonic motility and can result in greater absorption rates.
- Metabolic diseases, such as thyroid disease/DM can increase or decrease transit time, can cause either increased/decreased drug absorption.
- When the med passes through the esophagus without adequate water, can cause erosion. Distribution
- Drug distribution is affected by aging, particularly in individuals of smaller body size, decreased body water, higher body fat.
- Drugs distributed in water have a higher concentration in elders, and exert a more profound effect.

Osteoporosis: fragility fracture or by a BMD T score of −2.5 or lower in the femoral neck or hip bones; World Health Organization definition of osteoporosis is a bone mineral density less than 2.5 standard deviations or more than the mean of a young adult. physical signs kyphosis, evidence of oral bone loss, restrictive pulmonary problems (decreased thoracic cage volume) Osteopenia: body density t-score is between minus 1 and minus 2.5 , the patient has osteopenia. Low bone mineral density (BMD), evaluated by dual-energy x-ray absorptiometry (DXA) can predict fracture risk Bone strength- 70% is bone density (DXA score) & 30% is bone quality (unmeasurable) DEXA results are reported as t and z-scores. The t-score compares the patient's bone mass to the mean bone mass of a young adult. The z-score compares the patient with someone within their own same age group. The QCT is an expensive three-dimensional study. ultrasound at the heel, it's an inexpensive frequent screen and it is approved by the FDA. You've probably seen this performed at health fairs. AACE guidelines= bisphosphonates, or denosumab as first line therapy. Screening recommendations: normal bone density or mild osteopenia = rescreen in 15 years. Moderate osteopenia= rescreen in 5 years. Advanced osteopenia = rescreen yearly. Fragility fractures Defined as >40 years old & standing height fall causes hip, spine, forearm shoulder bone fracture meets criteria for fragility fracture Fragility fractures - vertebral and hip fractures worst morbidity and mortality risk Modifiable risk factors - ETOH, smoking, Vitamin D replete (muscle strength and bone density), calcium fortified foods & leafy greens, strength/ balance- work on weight bearing exercises for muscle strength and balance. Practice standing on 1 leg. Other risk factors: hyperthyroidism, diabetes, rheumatoid arthritis, chronic kidney disease, Cushing syndrome, liver disease, hyperparathyroidism, alcoholism, and a history of gastric bypass surgery or organ transplant. Women who experience early menopause without hormone replacement are at risk as well as people with malabsorption problems and anorexia. Peak bone mass occurs in adolescence and osteoporosis risk originates in adolescence with a failure to achieve a high quality of bone. Screen patients: annual height check & oral cavity check; age 50+ FRAX screen (10 year risk for fracture) http://www.shef.ac.uk/FRAX/ DXA - > or = 65 years old get bone density. If fragility fracture get DXA sooner. Drugs:
antiresorptive agents and anabolic agents- (long acting or shorter acting) bisphosphonates estrogens and parathyroid hormones risks: adverse effects and low adherence receptor activator of NF-κB ligand (RANKL) and sclerostin: Denosumab (Prolia and Xgeva)- monoclonal antibody that binds to RANKL, mimics osteoprotegerin (OPG), thereby inhibiting osteoclastogenesis. Romosozumab (Evenity), a monoclonal antibody that binds to and inhibits sclerostin, has the dual effects of promoting bone formation and inhibiting bone resorption Bisphosphonate drug holidays (per American society for bone and mineral research white paper)- consider after 3 - 5 years of maintenance for: pts at modest fracture risk. T score. Bisphosphonates slowly have reversal of their effects. DO NOT bisphosphonate holiday: T score in osteoporosis range, prior spine or hip or other osteoporotic fracture in prior 2 - 3 years; holiday 1-2 year & the re-eval the BMD and their risk factors. If BMD is stable (meeting osteoporosis level) or decreased – restart after 1 or 2 years off. Unproven which to restart at that time. If hip-bone density is quite low then a bisphosphonate isn’t a good choice, but Denosumab is a better choice at that time Monoclonal antibodies: Denosumab (Prolia and Xgeva) – bone remodeling effects go away quickly; fracture risk at pre tx level in few months after missed dose SERM selective estrogen receptor modulators- block estrogen effects at receptors in breast tissue, bones and the uterus Raloxifene (Evista) Drug holidays do NOT apply to SERMs or monoclonal antibodies Chronic pain: Assess for hyperalgesia (extreme, exaggerated reaction to pain stimulus) or allodynia (central pain sensitization- increased response of neurons to normally non-painful, repetitive, stimulation). Ask about OA, RA, previous fractures, and fibromyalgia. All of these contribute in the older adult to chronic pain. Assess the history of or current chemical dependency such as alcohol (CAGE), depression (PHQ-9, HAM-D), and anxiety (GAD7, HAM-A), review sleep and diet patterns. Assess pain location, intensity, quality, onset, duration, variation, rhythm, and manner of expressing pain, pain relief, what are some exacerbating triggers, the effects of the pain, and response to previous treatments. Pain assessment tools. And consider utilizing assessment tools for pain, addiction risk, depression, and functional status ADLs. Poorly managed psychological disorders can interfere with the patient's ability to be a part of their care and decrease the effectiveness of their treatment and increase the risk of suicide. Neuropathic pain (from pathology or damage to the nervous system)- DM neuropathy, post-herpetic neuralgia, or a stroke. Symptoms: numbness, paresthesia, allodynia, tingling, burning, shooting/stabbing pain; follows nerve path Nociceptive pain- caused by tissue damage, muscle pain, inflammatory pain. This includes arthritis infection, tendonitis, tissue injury, post-op pain, and chronic infections. Mechanical/compressive pain increases with activity and decreases with rest. muscle/ligament sprain or strain, degenerative of disks or facets, osteoporosis with compression fractures, fracture, obstruction, dislocation, or compression by a tumor, cyst, or bony structure
