Cytological Features

Background. Most age-related changes are associated with the progression of functional instability in organs and tissues. This requires promising definitions of biological age and the pace of the human body development based on laboratory and instrumental assessment of the structure and functions of tissues. The article describes the potential of buccal cells investigations. The purpose was to compare the cytological characteristics of buccal epithelial cells in patients of various age groups (children, young people, the elderly and senile). Methodology. The study of the cytological features of buccal epithelial cells involved patients (men and women) in accordance with the WHO age classification, which were divided into 4 groups. The first group included pediatric patients (under 18 years old, 231 people), the second group included young patients (18―44 years old, 121 people), the 3rd group included elderly patients (60―74 years old, 16 people), and the fourth group included senile patients (75 ―90 years, 5 people). Results. The authors presented buccal epithelium application in non-invasive diagnosis of early human aging; identified common cytological features of buccal epithelium for different ages; revealed the accumulation of cytogenetic abnormalities (epithelial cells with micronuclei, protrusions of the nucleus) and degenerative-dystrophic changes (perinuclear vacuole, condensed chromatin, karyorexis, karyolysis) with age. These findings reflect the predominance of apoptosis over reparation in the process of aging. Conclusions. On this basis, it can be assumed that the buccal cytogram reflects age-dependent processes and can serve as an adequate tool for studying the mechanisms of aging. Among various methods exfoliative cytology is a unique, noninvasive technique involving simple and pain-free collection of intact cells from the oral cavity for microscopic examination.

OBJECTIVE To review and evaluate the medical literature concerning antiepileptic drug (AED) therapy in elderly patients. DATA SOURCES A MEDLINE search (1982–December 2004) was conducted. Bibliographies of the articles identified were also reviewed, and an Internet search engine was used to identify additional pertinent references. STUDY SELECTION AND DATA EXTRACTION Clinical studies and reviews were evaluated, and relevant information was included. DATA SYNTHESIS The elderly have the highest incidence of seizures among all age groups. Complex partial seizures are the most common, followed by primary generalized tonic–clonic seizures. An accurate diagnosis may prove difficult because of a low suspicion of epilepsy in the elderly and other diseases that may mimic seizures. Most AEDs are approved for treatment of elderly patients who have partial and tonic–clonic seizures. However, a number of age-related variables should be addressed when selecting an appropriate AED. Age-dependent differences in pharmacokinetics and pharmacodynamics of AEDs must be taken into account. Drug–drug interactions must be considered since elderly people often take multiple medications. The ultimate factor that often determines AED selection is tolerability. CONCLUSIONS Numerous factors must be considered in treating elderly patients for seizures, but maximizing the ability of patients to tolerate drug therapy is often the basis for AED selection. Special consideration should be made along several lines, including elderly patients’ cognitive functioning and their tendency to respond to lower AED concentrations.

Background Risk for severe COVID-19 increases with age. Different vaccination strategies are currently being considered, including those aimed at slowing down transmission and those aimed at providing direct protection to those most at risk. Methods The objectives of the current study were i) to assess age-related incidence and survival between PCR-diagnosed COVID-19 cases (n = 61,993) in the Autonomous Community of Aragon from March to November 2020, and ii) to characterize age differences regarding the course of the disease in hospitalized patients in a tertiary university hospital. Results We found a similar incidence of COVID-19 in individuals between 10 and 79 years. Incidence increased in those over 80 years possibly because of the elevated transmission within the nursing homes. We observed a profound disparity among age groups; case fatality rates (CFRs) were near 0 in cases younger than 39 years throughout different waves. In contrast, there was an age-dependent and progressive increase in the CFRs, especially during the first pandemic wave. SARS-CoV-2 infection caused a more severe and rapid progression in older patients. The elderly required faster hospitalization, presented more serious symptoms on admission, and had a worse clinical course. Hospitalized older individuals, even without comorbidities, had an increased mortality risk directly associated with their age. Lastly, the existence of comorbidities dramatically increased the CFRs in the elderly, especially in males. Conclusion The elevated incidence of COVID-19 and the vulnerability of the elderly call for their prioritization in vaccination and targeted prevention measures specifically focused on this aged population.

AbstractPurpose:To investigate the relationship between age and Advanced Life Support (ALS) utilization.Population:All patients from 1 January 1987 to 31 December 1988 transported by ALS ambulances within Lebanon County, a rural/urban county of 112,000.Methods:All runs resulting in patient treatment by ALS personnel were tallied at five-year age intervals and sub-grouped by trauma- and non-trauma-related calls. Utilization rates for each age group were obtained by dividing the calls by the population of each group. Correlation with age was tested by Spearman's rank correlation. Treatment rates for age groups were calculated for the six most frequent medical etiologies. To illustrate the effect of age distributions, age rates were applied to projected state and national population distributions.Results:There was a significant correlation with age for all transports (p < .01; r=.93) and for those not related to trauma (p<.01; r=.98). Correlation was not detected for trauma-related responses (p>.10; r=.19). Non-trauma-related case incidence varied among age groups, ranging from 1.1/1,000 for age five through nine years to 89/1,000 for age 80–84 years. Congestive heart failure, cardiac ischemia, syncope, myocardial infarction, and cardiac arrest evidenced increased incidence with age. Seizure did not. Older populations had a higher projected utilization of ALS services than did the younger age groups.Conclusion:Non-trauma ALS utilization is highly dependent on the age of the patient. Due to projected aging of the population and increased utilization of ALS by the elderly, projected utilization will increase at a rate faster than will the population. Age:rate data can be combined with population projections to estimate future need.

The classification proposed by Woolner et al. (1961, 1971) has been applied to 139 cases of primary malignant tumors of the thyroid gland diagnosed in one of the largest hospitals of Rome, Italy, over a period of 5 years, from 1977 to 1981. These cases come from 1418 patients with enlargement of the thyroid surgically treated at the 5th Surgical Clinic of the University of Rome. All the histologic slides were re-examined, and the pathology records were re-evaluated. Of these tumors, 56.8% were papillary, 30.9% follicular, 9.3% anaplastic or undifferentiated, and 2.1% medullary. There was a female predominance in all age groups and for all types of tumors, reflecting a total female to male ratio of 1.9:1. Papillary carcinoma occurred most commonly in young and young-adult patients, follicular in the middle-age group, and anaplastic in the elderly. The extent of the primary tumor, the presence of regional metastases, and the association with other thyroid nonneoplastic diseases such as lymphocytic and Hashimoto's thyroiditis, and nontoxic and toxic goiter were also recorded. Multicentric rumors were found in 38.9% of cases principally represented by papillary carcinomas. Regional lymph node metastases were observed mainly in young patients, and no correlation was found between thyroid cancer incidence and other nonneoplastic thyroid diseases.

Abstract. Age-related alterations in pituitary-thyroid function were studied in 173 female patients with simple goitre and in 70 normal female subjects. They were divided into 4 groups according to age: A group, less than 19 years; B group, 20 to 29 years; C group, 30 to 39 years; D group, 40 to 59 years. Serum triiodothyronine (T3) concentrations decreased progressively but insignificantly with age in female patients with simple goitre and in normal female subjects, whereas serum thyroxine (T4) concentrations remained constant throughout the studied age range. Only in female patients with simple goitre, did basal serum TSH concentrations show a tendency to increase with age. However, thyrotrophin-releasing hormone (TRH)-stimulated increase of serum TSH was progressively augmented with age both in female patients with simple goitre and in normal female subjects; the magnitude of change was greater in the former group. As reflected by acute increases of serum T3 and T4 concentrations, thyroidal responsiveness to endogenous TSH was progressively depressed with age in female patients with simple goitre and in normal female subjects. This age-related thyroidal refractoriness to TSH was more apparent when the changes were expressed as ΔT3(stimulated T3 – basal T3)/ΔTSH (maximum TSH after TRH – basal TSH), and ΔT4(stimulated T4 – basal T4)/ΔTSH. ΔT4/ΔTSH was lower in female patients with simple goitre than in normal female subjects in all age groups. However, the difference was significant only for ΔT4/ΔTSH in group A. Thyroidal responsiveness to exogenous TSH also gradually declined with age in female patients with simple goitre. Our data indicate 1) TRH-stimulated TSH secretion increases with age probably to overcome age-related thyroidal refractoriness to TSH and 2) although the thyroid of patients with simple goitre is slightly less responsive to TSH than that of normal subjects for all age groups, the difference was significant only for young patients.

The Relationship

Vitamin D requirements are thought to vary with age, but there is little comparative evidence for this. One goal in establishing a vitamin D requirement is to avoid secondary hyperparathyroidism. We studied 1741 euthyroid, thyroid clinic outpatients without evidence of calcium abnormalities, ranging in age from 19 to 97 yr, whose serum and urine had been analyzed for calcium, vitamin D, and parathyroid status. We found no effect of age on the 25-hydroxyvitamin D [25(OH)D] concentration associated with specific vitamin D intakes, and there was no relationship between 25(OH)D and 1,25hydroxyvitamin D [1,25(OH)2D]. In every age group, serum 1,25(OH)2D declined with increasing creatinine (P &lt; 0.001). What changed with age included creatinine, which correlated with 25(OH)D (r = 0.146, P &lt; 0.001) only in the youngest age group (19–50 yr) but not in the older age groups (P &gt; 0.1). Creatinine did not correlate with PTH in the youngest age group, but the relationship became significant as age increased (e.g. for the elderly, r = 0.365, P &lt; 0.001). Linear regression of log PTH vs. log 25(OH)D agreed with the natural shape of the relationship observed with scatterplot smoothing, and this showed no plateau in PTH as 25(OH)D increased. We compared PTH concentrations among age groups, based on 20 nmol/liter increments in 25(OH)D. Mean PTH in adults older than 70 yr was consistently higher than in adults younger than 50 yr (P &lt; 0.05 by ANOVA and Dunnett’s t test). PTH levels of the elderly who had 25(OH)D concentrations greater than 100 nmol/liter matched PTH of younger adults having 25(OH)D concentrations near 70 nmol/liter. This study shows that all age groups exhibit a high prevalence of 25(OH)D insufficiency and secondary hyperparathyroidism. Older adults are just as efficient in maintaining 25(OH)D, but they need more vitamin D to produce the higher 25(OH)D concentrations required to overcome the hyperparathyroidism associated with their diminishing renal function.

187 Background: Older age is a risk feature in melanoma. Elderly are more likely to have immunosenescence, which could help melanoma cells escape immune surveillance. Hence, there is a belief that elderly people cannot mount a potent immune response to checkpoint inhibitors (CPI) to fully eliminate melanoma. The objective of the study was to investigate age-related differences in the time to progression (TTP), overall survival (OS), and immunotherapy related adverse events (irAEs) among patients with metastatic melanoma who received CPI. Methods: We retrospectively identified patients with stage IV melanoma who received at least 1 dose of ipilimumab, pembrolizumab, nivolumab, or combined ipilimumab and nivolumab. Demographics, pathologic, and clinical characteristics were obtained. Immune-related response criteria were utilized to define responses. Results: Sixty patients were included; 29 were less than 65 years old and 31 were 65 years or older. No significant differences, when adjusted for gender, type of melanoma and presence of brain metastasis, in TTP [HR 0.79; 95% CI (0.371.70); p = 0.46] and OS [Hazard ratio (HR) 0.75; 95% CI (0.31-1.82); P = 0.491] was observed between the < 65 and ≥65 year-old groups who received CPI for metastatic melanoma. Overall irAEs in two groups was comparable with 62% in the younger patients and 45% in the older patients (P = 0.19). Thirty responders had a median age of 66.9 (54.3-73.3 years old) and 30 non-responders had a median age of 62.7 (54-69.1 years old). Non-responders, regardless of age, were more likely to have BRAF mutated melanomas (53.3% vs. 27.6%; P = 0.04) and less likely to have irAEs (40% vs. 66.7%; P = 0.04) than responders. Conclusions: No difference in TTP, OS or irAEs was observed between the elderly and the young patients who received CPI for metastatic melanoma. In general, responders had higher irAEs and less BRAF mutated melanomas than non-responders.

Concepts Of Technology

Purpose – The prevailing mindset is that younger people value and more readily adopt technology. The purpose of this paper is to determine if this is true with respect to banking practices. Design/methodology/approach – A survey was conducted to evaluate the importance of mobile, online, and physical-based banking across multiple age groups. Factor analysis and analysis of covariance were used to evaluate the responses. Findings – The results show that older consumers see more value in traditional, physical-based banking, all ages are equally interested in currently emerging technologies (online), and younger users are more interested in the newest technologies. Research limitations/implications – The stereotype of technology-adverse elderly may be too limiting. Age influences are not absolute barriers enacted by time, but are potentially learned behaviors. Practical implications – Practitioners interested in introducing new technologies to the elderly might consider making their innovations more compatible with existing technologies already in use. Originality/value – This study builds on the concepts of technology adoption and previous work on aging as it relates to adoption. However, it is shown that cognitive declines are not the only factor that can explain age-related differences in technology usage. Cohort differences in experience and resources may also be important. This is of value not only to the banks, but to all businesses that rely on consumer use of technology to maintain the business relationship.

Purpose: Previous research, undertaken using a Super 8 camera and non-continuous data, has reported that with increasing age, people are more likely to sleep in the right lateral position. It has been postulated that this is due to age related alterations in cardiovascular function. This pilot study was undertaken to determine if collection and analysis of continuous sleep data was a feasible method for further investigation of this topic and to determine the sample size required for an adequately powered study. Increased understanding of age related changes in sleep position may provide valuable information to improve sleep quality and nursing care of the elderly person. Method: Research at the Centre for Sleep Research, University of South Australia, investigated the association between age and sleep position. Infra-red illumination and video cameras recorded the sleep patterns of 12 subjects for two nights. Videos were examined and the amount of time spent in each sleep position was calculated in seconds. Results: In a one-way analysis of variance, sample sizes of 19, 19, and, 19 are necessary from the three age groups whose means are to be compared. The expected means are 20, 25 and 45 for the three age groups respectively. The total sample of 57 subjects achieves 82% power to detect differences among the means versus the alternative of equal means using an F test with a 0.05 significance level.Conclusions: The results of this pilot study support further investigation of the relationship between age and lateral sleep position preference, and particularly the physiological parameters which may underpin the adoption of different sleep positions with increasing age. The described method is appropriate and modifications are suggested to further improve future studies.

Effect Of Age

The aim of the present study was to assess the influence of age on plasma concentration of α-tocopherol, retinol and carotenoids with a special attention paid to natural differences in body composition. Forty healthy subjects were recruited: twenty were less than 35 years old and twenty above 60 years old. Males and females were equally represented in each age group. Subjects were kept in energy balance and received controlled diets for 36 h. Fat mass and fat-free mass were determined with the180-enriched water dilution technique. Plasma vitamins A and E, and carotenoid levels were determined after 12 h fasting and were shown to be similar in women and men. Plasma α-tocopherol concentration increased with age (+44 % elderlyv.young), and correlated with % fat mass and plasma cholesterol. After adjustment for plasma cholesterol, the effect of age and % fat mass disappeared. In contrast, plasma lycopene level was 2-fold lower in the elderly than in the young group, and was inversely correlated with fat mass. When lycopene values were adjusted for fat mass, the effect of age disappeared. These results suggest that plasma levels of vitamin E and lycopene differed in the two age groups and that differences in plasma cholesterol and fat mass might participate in such an effect. Short-term vitamin intake did not appear to influence plasma vitamin concentrations.
