Elderly and younger patients selected to undergo coronary angiography.

OBJECTIVE--To establish and compare the characteristics of older (greater than or equal to 70 years) and younger patients with chest pain selected to undergo coronary angiography and by analysis of their subsequent management to assess the value of coronary angiography for older patients with chest pain. DESIGN--Retrospective analysis of clinical case notes and coronary angiography reports. SETTING--Cardiology department with referral population of one million in an Edinburgh hospital. PATIENTS--134 consecutive patients with chest pain aged 70 years or over investigated by coronary angiography between 1978 and 1988; 134 randomly selected patients aged under 70 investigated over the same period. MAIN OUTCOME MEASURES--Clinical and angiographic features at time of angiography and management after angiography. RESULTS--Older patients represented a small, but increasing, proportion of those investigated. Older patients had more severe symptoms at the time of angiography, were taking more antianginal drugs, and had had their symptoms for longer than younger patients. At angiography more older patients had triple vessel coronary disease, left main stem stenosis, or left ventricular impairment. After angiography similar proportions of older and younger patients underwent coronary artery surgery, with more elderly patients requiring urgent operation; although operative mortality was higher for elderly patients, symptomatic benefit was similar to that in younger patients. CONCLUSIONS--Older patients with angina selected to undergo coronary angiography and subsequent coronary surgery have more severe symptoms and underlying cardiac disease. Earlier referral and investigation might yield a population with lower operative risk. Selection of patients for coronary angiography and coronary artery surgery should be based on the potential for benefit and should avoid "agism."     

Nuclear medicine studies of aging—I. Procedure utilization in the oldest old

Analyses of procedure utilization are of importance if accurate projections are to be made of local and national needs as the population ages. Nuclear Medicine records of a general hospital were analyzed for 1986, to determine utilization patterns in the oldest old (age 85 years and greater) as compared with younger patients. The most elderly comprised 1.3% of the population of this state, but “consumed” 3.9% of the studies carried out in Nuclear Medicine (or a rate 3 times greater than expected). The average number of procedures/patient during the year was 1.56 in the oldest old vs 1.57 in younger individuals. The sex ratio of procedure utilization was 65% female (slightly lower than state wide national estimates of the female portion of the population). A far lower percentage of studies were performed as outpatients in the oldest old (12.2%) than in the younger population (44.9%); contributing factors were discussed. Of the procedures, several had the same percentage utilization in the oldest old and younger groups (gated cardiac blood pool, liver plus hepatobiliary, and radiogallium imaging). Bone scans were slightly less common in the very elderly. However, thyroid studies and radiothallium cardiac imaging were performed significantly less frequently in the more elderly. Procedures carried out more frequently in the very elderly were gastrointestinal bleeding examinations and lung imaging. Possible reasons for this were pointed out.     

Feasibility of Image-Guided Radiotherapy for Elderly Patients with Locally Advanced Rectal Cancer

Purpose

The study aims to assess the tolerance of elderly patients (70 years or older) with locally advanced rectal cancers to image-guided radiotherapy (IGRT). A retrospective review of 13 elderly patients with locally advanced rectal cancer who underwent preoperative chemoradiation using IGRT was performed. Grade 3–4 acute toxicities, survival, and long-term complications were compared to 17 younger patients (<70 years) with the same disease stage.

Results

Grade 3–4 hematologic toxicities occurred in 7.6% and 0% (p = 0.4) and gastrointestinal toxicities, and, in 15.2% and 5% (p = 0.5), of elderly and younger patients, respectively. Surgery was aborted in three patients, two in the elderly group and one in the younger group. One patient in the elderly group died after surgery from cardiac arrhythmia. After a median follow-up of 34 months, five patients had died, two in the elderly and three in the younger group. The 3-year survival was 90.9% and 87.5% (p = 0.7) for the elderly and younger group respectively. Two patients in the younger group developed ischemic colitis and fecal incontinence. There was no statistically significant difference in acute and late toxicities as well as survival between the two groups.

Conclusions and Clinical Relevance

Elderly patients with locally advanced rectal cancers may tolerate preoperative chemoradiation with IGRT as well as younger patients. Further prospective studies should be performed to investigate the potential of IGRT for possible cure in elderly patients with locally advanced rectal cancer.     

The Yad Sarah geriatric dental clinic, a different model

Introduction: There are not sufficient dental services for elderly people around the world. Yad Sarah is an Israel‐wide network of volunteers aiding sick, elderly, isolated and housebound people with an array of services aimed at making home care possible. It provides medical and social services to more than 380 000 elderly persons per year and in addition, lends medical equipment free of charge, has day rehabilitation centres, legal aid council for seniors, provides transportation for the disabled, meal deliveries and geriatric dental services. Materials and methods: The latter are equipped with five dental units (one mobile unit) and a dental laboratory. During the 5 years from 2000 to 2004 the dental services provided dental care for 3890 elderly patients with the main clinic located in Jerusalem. Patients pay an average of 70% of the cost price of their dental care, with the difference being subsidised by Yad Sarah. Of the 515 patients who applied for treatment in 2004, 54% possessed natural teeth in both jaws, 28% were fully edentulous, 12% were edentulous in the maxilla and 6% were edentulous in the mandible. Females applied for dental treatment more often than the male population. Older patients (75–101 years old) required oral care at their homes or at old age residences, more frequently than the younger age groups (60–74 years old). Conclusion: Dental treatment was administered by 70 volunteer dental surgeons, two certified dental hygienists and dental hygienist students. The clinical staff was provided with a comprehensive in‐service training in geriatric dentistry during the 3‐year service learning period. A survey in 2004 showed that 83% of the selected patients were satisfied, compared with 14% who were not. The reasons for satisfaction were, mainly, the personal relationship with the attending staff (41%) and the professional ability of the dental team (46%).     

Myocardial Revascularization in Patients 70 Years of Age and Older

Myocardial revascularization has been carried out by us in 67 patients 70 years of age or older. Advanced coronary artery disease was found at angiography in more than two thirds of the patients. The postoperative morbidity and mortality compare very favorably with those in younger patients. The early and late mortality in the 67 patients was 4.5 percent and 6.0 percent, respectively. Fifty-seven survivors have been followed an average of 21 months; for most patients there has been a pronounced improvement in clinical classification. Properly selected, patients of advanced age can undergo successful revascularization surgical procedures. The adequacy of function of the left ventricle, proper timing of the surgical operation and an aggressive yet realistic approach seem to be major determinants for a good result.     

Under-use of adjuvant chemotherapy in women aged ≥70 years diagnosed with breast cancer in a university hospital

Introduction

Patient age often limits the therapeutic efforts of the oncologist. The aim of this study was to determine whether chemotherapy is used less frequently in elderly women aged 65-69 years diagnosed with breast cancer, compared to younger women.

Methods

A retrospective study was performed including women greater than 65 years old who had localised breast cancer and were treated at a University Hospital. Patients were classified into two groups, 65-69 years old and ≥ 70 years old. The differences in patient characteristics, tumour characteristics, chemotherapy treatment and chemotherapy-associated toxicity were analysed in both groups.

Results

A total of 164 women, with an average age of 73.7 years, were included in this study. There were no significant differences in the characteristics of the patients or their tumours. However, 75% of women <70 years old were treated with chemotherapy compared to just 34% of the older women (P<.001). The resulting levels of toxicity were similar between age groups.

Conclusions

Women ≥ 70 years old were treated with chemotherapy less frequently, even though the features and tumour characteristics of the women, as well as the toxicity of the treatment, were similar to that in younger women.     

Comorbidities and Crash Involvement among Younger and Older Drivers

Previous studies identified comorbidities as predictors of older driver performance and driving pattern, while the direct impact of comorbidities on road crash risk in elderly drivers is still unknown. The present study is a cross-sectional aimed at investigating the association between levels of comorbidity and crash involvement in adult and elderly drivers. 327 drivers were stratified according to age range in two groups: elderly drivers (age ≥70 years old, referred as older) and adult drivers (age <70 years old, referred as younger). Driving information was obtained through a driving questionnaire. Distance traveled was categorized into low, medium and high on the basis of kilometers driven in a year. CIRS-illness severity (IS) and CIRS-comorbidity indices (CI) in all populations were calculated. Older drivers had a significantly higher crash involvements rate (p = .045) compared with the younger group based on the number of licensed drivers. Dividing comorbidity indices into tertiles among all licensed subjects, the number of current drivers significantly decreased (p<.0001) with increasing level of comorbidity. The number of current drivers among older subjects significantly decreased with increasing comorbidity level (p = .026) while no difference among younger group was found (p = .462). Among younger drivers with increasing comorbidity level, the number of road accidents significantly increased (p = .048) and the logistic regression analysis showed that comorbidity level significantly associated with crash involvement independent of gender and driving exposure. Older subjects with high level of comorbidity are able to self-regulate driving while comorbidity burden represents a significant risk factor for crash involvements among younger drivers.     

Nephrotic Syndrome in the Elderly

Though the nephrotic syndrome is generally believed to be uncommon in the elderly, patients aged 60 years or more accounted for 25 out of 100 consecutive adult cases. Six (24%) of these had the minimal change lesion, compared with 16% of the younger adults. The incidence of membranous glomerulonephritis was similar in the two age groups, but proliferative glomerulonephritis was more common in the younger (29%) than in the older group (16%). Amyloidosis did not have a higher incidence in the higher age group. Five of the elderly patients with minimal change lesion were treated with prednisone—in four a complete remission from the nephrotic syndrome followed, while the fifth patient''s course is unknown.These results suggest that, when the patient''s other circumstances allow, the nephrotic syndrome in an elderly patient should be investigated and managed as in younger age groups.     

Arterial hypertension associated with hyper and hypothyroidism]

45 patients with hyper and hypothyroidism in the time 1989-1990 were observed. The Graves' disease was diagnosed in 29 and rather in the younger patients, but 16 had the toxic nodular goiter and those were elderly. In 27 the hypertension was secondary (symptomatic) and after the successful treatment of the hyperthyroidism was completely controlled. In 14 cases the hypertension was primary (essential) and the application of the hypotensive drugs was also necessary. Among 4 patients with primary hypothyroidism and associated hypertension and coronary insufficiency the early treatment by the thyroid preparation was successful: the blood pressure was lowered and the coronary insufficiency was improved; but if the replacement therapy was stopped and the hypothyroidism was relapsed, the blood pressure was increases and the coronary insufficiency was aggravated. Conclusions: 1. The secondary (symptomatic) hypertension associated with the hyperthyroidism may be controlled by successful treatment of the thyrotoxicosis, but the primary (essential) must be treated by the hypotensive drugs also. 2. The early treatment of the hypothyroidism may control the associated hypertension and the coronary insufficiency. 3. Graves' disease is associated mostly with symptomatic hypertension, in nodular toxic goiter in most of the cases the essential hypertension was established.     

Does chronological age reduce working ability?

Definitions of so-called older age often are based on a chronological age of 65 years and over, although by some authors aging is the process that starts after the 30th year of life. At the beginning occur changes in the organ functions, followed by anatomical changes as well. Some organs age faster, some slower. For example, kidneys decrease for one third, lungs do not change, liver shrinks a little, prostate increases twice. In some cross-sectional studies, muscle mass in men aged 65 is on average 12 kg less than in the so-called middle age, and in women it is approximately 5 kg less. In the heart the amount of connective tissue increases, lipofuscin is deposited in cardiac muscle, the strength of which is decreasing. In the respiratory tract the number of pathways cilia decreases, along with the alveolar surface, muscles involved in breathing change, lung elasticity is also diminished. But, in regard with the previous body capacity, "physiological aging" can be divided into three types of elderly: the "older" elderly have the highest functional capacity of 2-3 MET (MET--metabolic unit, i.e. the oxygen consumption of 3.5 ml/kg body mass in a minute), the "younger" elderly are the persons of older age having maximal functional capacity of 5-7 MET, while the "sport" elderly have the functional capacity of 9-10 MET, disregarding chronological age. The brain weight diminishes for approximately 7% compared to younger age. In temporal gyrus and area striata even 20-40% of cells are being lost, vacuolar and neuroaxonal degeneration occurs, lipofuscin is being accumulated. The brain blood flow, which is in normal conditions 50-60 ml/min/100 g of tissue, with the increase of biological age decreases to about 40 ml/min/100 g of tissue. However, this usually is not the consequence of biological age but of disease. A chronological age of 65 for the beginning of "elder hood" is a sociopolitical construct developed by social security systems and government organizations to decide an arbitrary age at which benefits should be paid. Thus, it neither a border nor do changes designating old age occurs exactly with that "age border". The changes in the organism during the so-called aging are individual. So, the functional capacity of an organism, both physical and intellectual, must be evaluated individually, having in mind biological age.     

Age and sex dependence of hemodynamic parameters of human internal carotid arteries

The study of the ultrasound diameter, linear velocity, and resistance of the internal carotid arteries in 647 subjects of both sexes aged from 1 to 74 years has been performed. Additionally, shear stress and the Reynolds number have been calculated. During the period from early childhood to adolescence and from the first mature to younger elderly ages, there is an increase in the diameter of the internal carotid arteries. Phases of an increase in the vascular resistance by the first period of childhood, adolescence, and younger elderly age are observed. The space flow velocity has relatively stable parameters till youth, and then it declines by younger elderly age. The average linear velocity, shear stress, and the Reynolds number progressively diminish twice by younger elderly age. Laminar blood flow with local twists in the early stages of postnatal ontogenesis is characteristic of the internal carotid arteries. The diameter of the internal carotid arteries, vascular resistance index, and blood flow velocity are higher in men than in women during most age periods. Shear stress in both internal carotid arteries during all the age periods studied is symmetrical and has no sex differences.     

Multivisceral resection of pancreatic neuroendocrine tumours: a report of two cases

Background

Compromised physiological reserve, comorbidities, and the natural history of pancreatic cancer may deny pancreatic resection from elderly patients. We evaluated outcomes of elderly patients amenable to pancreatic surgery.

Methods

The medical records of all patients who underwent pancreatic resection at our institution (1995-2007) were retrospectively reviewed. Patient, tumor, and outcomes characteristics in elderly patients aged ≥ 70 years were compared to a younger cohort (<70y).

Results

Of 460 patients who had surgery for pancreatic neoplasm, 166 (36%) aged ≥ 70y. Compared to patients < 70y (n = 294), elderly patients had more associated comorbidities; 72% vs. 43% (p = 0.01) and a higher rate of malignant pathologies; 73% vs. 59% (p = 0.002). Operative time and blood products consumption were comparable; however, elderly patients had more post-operative complications (41% vs. 29%; p = 0.01), longer hospital stay (26.2 vs. 19.7 days; p < 0.0001), and a higher incidence of peri-operative mortality (5.4% vs. 1.4%; p = 0.01). Multivariable analysis identified age ≥ 70y as an independent predictor of shorter disease-specific survival (DSS) among patients who had surgery for pancreatic adenocarcinoma (n = 224). Median DSS for patients aged ≥ 70y vs. < 70y were 15 months (SE: 1.6) vs. 20 months (SE: 3.4), respectively (p = 0.05). One, two, and 5-Y DSS rates for the cohort of elderly patients were 58%, 36% and 23%, respectively.

Conclusions

Properly selected elderly patients can undergo pancreatic resection with acceptable post-operative morbidity and mortality rates. Long term survival is achievable even in the presence of adenocarcinoma and therefore surgery should be seriously considered in these patients.     

Direct costs of coronary artery bypass grafting in patients aged 65 years or more and those under age 65

BACKGROUND: Over the past 20 years, there have been marked increases in rates of coronary artery bypass grafting (CABG) among older people in Canada. The objectives of this study were to accurately estimate the direct medical costs of CABG in older patients (age 65 years or more) and to compare CABG costs for this age group with those for patients less than 65 years of age. METHODS: Direct medical costs were estimated from a sample of 205 older and 202 younger patients with triple-vessel or left main coronary artery disease who underwent isolated CABG at The Toronto Hospital, a tertiary care university-affiliated hospital, between Apr. 1, 1991, and Mar. 31, 1992. Costs are expressed in 1992 Canadian dollars from a third-party payer perspective. RESULTS: The mean costs of CABG in older and younger patients respectively were $16,500 and $15,600 for elective, uncomplicated cases, $23,200 and $19,200 for nonelective, uncomplicated cases, $29,200 and $20,300 for elective, complicated cases, and $33,600 and $23,700 for nonelective, complicated cases. Age remained a significant determinant of costs after adjustment for severity of heart disease and for comorbidity. Between 59% and 91% of the cost difference between older and younger patients was accounted for by higher intensive care unit and ward costs. INTERPRETATION: CABG was more costly in older people, especially in complicated cases, even after an attempt to adjust for severity of disease and comorbidity. Future studies should attempt to identify modifiable factors that contribute to longer intensive care and ward stays for older patients.     

Management of elderly patients with a non-ST-segment-elevation acute coronary syndrome

Elderly patients with an acute coronary syndrome are underrepresented in randomised controlled trials. Neither the European Society of Cardiology nor the American Heart Association/American College of Cardiology acute coronary syndrome guidelines provide specific recommendations for elderly patients. However, elderly patients are at higher thrombotic and bleeding risk compared with younger patients leading to difficulties in choosing the optimal treatment. In this review, we discuss the uncertainties we encounter in treating elderly patients with non-ST-elevation acute coronary syndrome and suggest treatment options based on the existing literature.     

Age-Related Disparity in Immediate Prognosis of Patients with Triple-Negative Breast Cancer: A Population-Based Study from SEER Cancer Registries

Background

Triple-negative breast cancer (TNBC) has been demonstrated to carry poor prognosis, but whether or not there exists any age-related variation in TNBC outcomes has yet to be elucidated. The current population-based study investigated the early survival pattern of elderly women with TNBC and identified outcome-correlated factors.

Patients and Methods

We searched the Surveillance, Epidemiology, and End Results (SEER) database and enrolled female primary non-metastatic TNBC cases. The patients were subdivided into elderly (≥70 years) and young groups (<70 years). The survival status of elderly patients was compared to that of the younger women. The primary and secondary endpoints were cancer-specific survival (CSS) and overall survival (OS) respectively.

Results

9908 female TNBC patients diagnosed from 2010 to 2011 were included in the current study (20.4% elderly). Elderly patients with relatively advanced diseases exhibited distinctly worse cancer-specific (log-rank, p<0.001) and overall survival (log-rank, p<0.001) than their young counterparts. Advanced age at diagnosis (≥70 years) was significantly predictive of poor outcome in terms of CSS (hazard ratio (HR), 2.125; 95% confidence interval (CI), 1.664 to 2.713; p<0.001) and OS (HR, 3.042; 95%CI, 2.474 to 3.740; p<0.001). Underuse of curative treatment especially radiotherapy was more prevalent in elderly women with stage II or III diseases than in younger patients.

Conclusion

Elderly patients with TNBC displayed elevated early mortality within the first two years of diagnosis compared to the younger individuals. The observed lower rate of loco-regional treatment might be associated with worse cancer-specific outcome for these patients.     

Breast cancer in the elderly—Should it be treated differently?

Breast cancer risk increases with age and about a third of female breast cancers are diagnosed in patients aged older than 70. Breast cancer in the elderly has, however, poorer outcome with lower survival rate compared to younger subjects. This may be partly explained by the delay in diagnosis and the ‘under-treatment’ of elderly breast cancer patients. In this review I try to provide recommendations for screening, surgery, radiotherapy, (neo)adjuvant hormone treatment and chemotherapy, and also the treatment of metastatic disease. Since large randomised trials usually exclude elderly patients with breast cancer, there is still an insufficient evidence for the treatment of such patients.     

Secular decline in mortality from coronary heart disease in adults with diabetes mellitus: cohort study

Objective To examine trends in fatal coronary heart disease in adults with and without diabetes.Design Cohort study.Setting Two surveys of the Nord-Trøndelag health study (HUNT), a population based study in Norway.Participants 74 914 men and women from the first survey (1984-6) and 64 829 from the second survey (1995-7).Main outcome measure Age specific mortality from coronary heart disease among adults with and without diabetes during two consecutive nine year follow-up periods.Results A total of 2623 men and 1583 women died from coronary heart disease. Mortality rates were substantially lower during the most recent follow-up period: among men aged 70-79 without diabetes, deaths per 1000 person years declined from 16.38 to 8.79 (reduction 48%, 95% confidence interval 39% to 55%) and among women aged 70-79 from 6.84 to 2.68 (62%, 52% to 70%). Among the same age group with diabetes, deaths per 1000 person years in men declined from 38.97 to 17.89 (54%, 32% to 69%) and in women from 28.15 to 11.83 (59%, 37% to 73%). The reduction was more noticeable in age groups younger than 70 at baseline, and less pronounced among people aged 80 or more. Mortality from coronary heart disease was more than twofold higher in people with than without diabetes, with a slightly stronger association in women. The difference in mortality by diabetes status remained almost unchanged from the first to the second survey.Conclusion The strong general reduction in mortality rates from coronary heart disease from the first to the second follow-up period also benefited people with diabetes, but the more than twofold higher mortality from coronary heart disease associated with diabetes persisted over time.     

The importance of the age factor in cancer vaccination at older age

Cancer is an age-related disease, and with the graying of the society there is an increasing need to optimize cancer management and therapy to elderly patients. Vaccine therapy for cancer is less toxic than chemotherapy or radiation and could be, therefore, especially effective in older, more frail cancer patients. However, it has been shown that older individuals do not respond to vaccine therapy as well as younger adults. This has been attributed to T cell unresponsiveness, a phenomenon also observed in cancer patients per se. Therefore, research is needed to establish whether age-specific tumor-immunological variables permit optimal use of cancer vaccines and therapy in the elderly. This review summarizes the current knowledge of T cell unresponsiveness in cancer patients and elderly, and the results of cancer vaccination in preclinical models at young and old age. Finally, new directions that may lead to effective cancer vaccination at older age will be proposed.
