[Heart morphologic state in retired fighter pilots].

Objective. To study the heart morphology in the retired fighter pilots, and to provide clinical evidence for protection combined G-loads (+ Gz), heat, noise, hypoxic and vibration stress induced cardiac structural damage. Method. Parameters of heart morphology were studied using Doppler echocardiography in 40 retired fighter pilots with 40 veteran cadres as control. Result. LVDd, LVDs, LADs, LVEDV, LVPWs and LVM in pilot group were somewhat higher than those in control group (NS); while IVSs and LVMI in pilot group were slightly lower than those in control group (NS); LVESV, aortic valve area, internal diameter of the ring and sinus in pilot group were significantly higher than those in control group (P < 0.05). Conclusion. Analysis of the results revealed no pathomorphologic damage of the heart. It suggest that all the variations can be regarded as adaptive changes due to the effects of the combined environmental factors experienced in long time flying.

Dental health of elderly in retirement homes of two cities in south Croatia--a cross-sectional study.

OBJECTIVE: A survey of dental health status was conducted in institutionalized elderly in South Croatia in order to assess the oral health of the elderly population. PARTICIPANTS: In 274 institutionalised elderly from five retirement homes in Split and Korcula we registered dental status according to World Health Organization criteria. The mean age of the patients was 81 +/- 8; there were 220 female and 54 male subjects. RESULTS: A total of 192 (70.0%) were totally edentulous, and additional 39 (14.2%) were edentulous in one jaw. A significantly higher prevalence of edentulousness with the increasing age was recorded. The mean number of remaining sound teeth, decayed teeth and radices relictae in the elderly decreased with increasing age. CONCLUSIONS: The elderly population in retirement homes in South Croatia has poor dental health. This calls for action to improve dental health and implement some special features in the dental health service programs for the institutionalised elderly.

The role of work in the lives of retired men following stroke.

A study was conducted with the purpose of describing self-perceived occupational role performance and to explore the possibility that role is a concept that is understood and utilised in the planning and performance of meaningful occupations. The participants were thirteen men who had experienced a stroke and undergone rehabilitation. The naturalistic methodology employed included a single extensive interview to establish and describe self-perceived roles and occupational role performance, followed by role sorting and role rating tasks. Data from the tasks were used to verify transcript analysis data. The findings of this study as they relate to the concept of work are described. Work as perceived by the study participants was found to continue beyond retirement and the advent of disability. Work roles, work occupations and workful elements of occupational performance were identified. For some participants a sense of being productive was highly significant to their feelings of well-being and social fit. A number of strategies were employed by participants to enable them to continue to do work. It is suggested that work should be considered in rehabilitation even beyond retirement.

Preparing for asset retirement.

Statement of Financial Accounting Standards (SFAS) No. 143 requires organizations to recognize a liability for an asset retirement obligation when it is incurred--even if that occurs far in advance of the asset's planned retirement. For example, organizations must recognize future costs associated with medical equipment disposal that carries hazardous material legal obligations.

Jobs of persons working after receiving retired-worker benefits.

This article describes the jobs of new Social Security retired-worker beneficiaries about 2 years after they received their first benefit payment and compares the characteristics of these jobs with those of jobs they were in before they received a benefit. The data are from the Social Security Administration's 1982 New Beneficiary Survey (NBS). The NBS data show that more than one-fifth of the new retired-worker beneficiaries were working 18-30 months after receipt of their first benefit payment. Most of the respondents usually worked less than full time at modest hourly wages rates--often for fewer hours and at lower wages than on the jobs they were in before benefit receipt. Thus, their annual earnings generally also were modest. The working NBS respondents were employed in all categories of occupations, but the majority were in white-collar jobs, often in the same major occupational or industrial category that they had been in before benefit receipt. When job changes had occurred, the tendency was to move into work in the service industries. Those individuals who were working were only slightly more likely to be self-employed in the postbenefit period than they had been in the prebenefit period.

Adrenal cortex in retired breeder Mongolian gerbils (Meriones unguiculatus) and golden hamsters (Mesocricetus auratus).

Alterations occur predominantly in cells of the zona reticularis in retired breeder Mongllian gerbils and golden hamsters. In gerbils, the size and number of lipid droplets increased and numerous large lipid-lysosomal complexes were observed in zona reticularis parenchymal cells or in macrophages, which were more numerous than in younger animals. Abundant lipofuchsin pigment was observed in zona reticularis parenchymal cells, and mitochondria contained electron-opaque inclusions. In the hamster, lipid droplets were present in inner zona reticularis cells and there was an increased amount of pigment within macrophages. Some of the alterations in gerbils and hamsters may at least in part reflect a stimulation of zona reticularis cells in retired breeders, attributable to increased prolactin secretion.

Nickel concentrations in nasal mucosa, plasma, and urine in active and retired nickel workers.

The objective of the present investigation was to study the influence of the occupational nickel exposure on the concentration of nickel in nasal mucosa, plasma and urine. Plasma, urine and biopsy specimens of nasal mucosa from 318 nickel workers, 15 retired nickel workers and 57 non-exposed controls were analyzed for nickel by atomic absorption spectrometry. The results showed that nickel exposure led significantly to raised nickel concentration in nasal mucosa, plasma and urine both in active and retired nickel workers. The average nickel concentration in the nasal mucosa was highest in workers exposed to the highest atmospheric nickel concentration, inhaled as nickel subsulphide and oxide dust. Workers exposed to aerosols of nickel chloride and sulphate at a lower atmospheric nickel concentration had, on the other hand, the highest mean nickel concentration in plasma and urine. The mucosal, plasma and urine nickel concentration were significantly correlated to duration of nickel exposure. The accumulated nickel in the nasal mucosa was retained for years after termination of the nickel exposure, and slowly released with an estimated half-life of 3.5 years.

Incidence of spontaneous tumors in a group of retired breeder female brown Norway rats.

A group of 80 female retired breeder inbred Brown Norway (BN) rats with recorded breeding histories was followed for 150 weeks with regard to spontaneous occurrence of tumors. The median survival time of the whole group was 134 weeks. Ninety tumors (42 benign tumors, 23 sarcomas, and 25 carcinomas) were found in 64 animals. Compared with previous findings on virgin female BN rats, the retired breeders used in the present study had a strikingly higher incidence (34%) of tumors of the genital system but a lower incidence (4%) of breast tumors. The breeding histories revealed no relationship between the recorded number of litters, number of newborns, age of the mother at the time of her first litter, preweanling mortality, and the occurrence of cancer or survival in general. Although all animals were kept under identical environmental conditions, animals born in the period July-December appeared to have a lower incidence of utero-vaginal tumors than animals born in the first half of the year. The growth rates of 32 tumors inoculated into syngeneic rats were monitored for 26 weeks. They did not correlate with the histopathologic characteristics of the specific tumor. Malignant or benign tumors showed the same growth variability.

[Clinical and capillaroscopic study of Raynaud's phenomenon in retired patients previously exposed to vinyl chloride monomer].

UNLABELLED: The course of Raynaud's phenomenon (RP) after the end of exposure to vinyl chloride monomer (VCM) is not really well known. Fourty four subjects were studied, from 128 retired patients who were exposed to VCM (end of the exposure since 8 years at least): 17 complained of "white finger crisis", and 27 voluntary retired subject without complaints (table II). The aims of this study were to specify capillaroscopic and clinical characteristics of these complaints to define and to assess the role of VCM. Each patient underwent an interview, a clinical examination and a nailfold capillary microscopy examination. RESULTS: 1) The 17 pensioners with complaints suffered from RP. But for 12 of them the onset of RP was in the exposed period (table I). From the clinical interview, the clinical and capillaroscopic examinations in these 12 RP may be attributed to the past exposure to VCM. 2) The majority of 44 subjects showed no capillary abnormalities. For 3 subjects changes consisted in isolated capillary dystrophia (1 with PR, 2 without PR) and for 2 subjects changes consisted in isolated neocapillaries (1 with PR, 1 without PR). The other microvascular changes were not specific (table III). In conclusion, RP secondary to VCM can still persist after the end of exposure in patients who suffered from RP during the exposure, 9% of the population (12/128). In view of discordance of clinical symptoms and capillaroscopic abnormalities, capillary lesions did not appear as the main physiopathologic factor in the persistence of the PR secondary to CVM.

Retiring some myths about aging and oral health.

Research on the oral health status of elderly populations has been limited in frequency and scope. There is a lack of good descriptive and longitudinal data on salivary gland function, oral mucosal status, and oral sensory performance in health and disease across the adult life span. Thus, confusion for practitioners and patients alike arises from unsubstantiated stereotypes about aging and oral health. There are some commonalities in the origins of the myths discussed in this article. First, many aging generalizations were based on studies that did not account for the health and medication status of the subjects. Second, most aging studies are cross-sectional designs which can result in misleading conclusions due to the age cohort effect. Third, many studies on the histology of aging oral tissues were laboratory animal studies, with results that cannot be generalized to human populations. Fourth, findings on oral health changes are often confounded or influenced by differences in functional status (e.g., the ability to care for oneself), nutritional health, health beliefs and expectations within the study subjects. Fifth, other changes due to aging may have an indirect effect on oral health, for example, an age-related decline in immune function. Sixth, the "older-old" group of elderly commonly labor under misconceptions of normal aging changes. Historically they have not sought dental care as often as the younger elders. This health care seeking behavior is expected to change dramatically when the baby boom generation joins the elderly ranks. The goals of oral health care for the elderly are consistent with those of other health care providers involved in geriatric care, namely maximizing functional performance, fostering independence, and enhancing their quality of life. Dental professionals would be well advised to apply a healthy dose of skepticism to any generalizations about debilitating changes in oral health due to aging alone. Most changes in oral health experienced by the elderly are not the result of age itself, but are the consequences of systemic disease, pharmacotherapy, functional disabilities, and cognitive impairment. When unexplained deleterious changes are seen in the oral health of elderly patients, the knowledgeable and reflective practitioner will account for local, systemic, and environmental factors in formulating a plan of care. In the opening paragraph, questions were posed about the mucosal integrity of a "little old lady." The most beneficial approach for her and all our older patients is to plan treatment utilizing current knowledge about aging and avoiding the traps created by myths and stereotypes. It is time to retire these myths before the baby boomers join the ranks of the retired.

International retirement migration in Europe.

"This paper presents a review and prospectus of international retirement migration (IRM), dealing mainly with European evidence but also referring to some analogous trends in North America. The paper is in three main parts. It first makes the case for regarding IRM as a significant aspect of population geography and of migration studies; in certain areas of Mediterranean Europe, IRM also has effects on regional economic geography. The second section of the paper discusses some of the early findings from a comparative study of British elderly residents in Tuscany, Malta, the Costa del Sol and the Algarve.... The final part of the article offers further reflections on why IRM is important--for the individual migrants themselves, for the host communities, and for public policy."

Retired and former asbestos workers in Hawaii.

In 1979, a pilot survey defined respiratory status and unmet health care needs of retired and former male asbestos workers in Hawaii. Of 1,401 identified subjects, 741 were contacted and 411 were interviewed. Forty-five subjects were between 39 and 54 years of age; 208, between 55 and 64; and 158, age 65 or more. They represented the main ethnic groups--Caucasian, Chinese, Filipino, Hawaiian and part-Hawaiian, and Japanese--on Oahu. Most subjects had had significant exposure to asbestos in a shipyard, and 83% were current nonsmokers (160 had never smoked, and 111 were ex-smokers for ten years or more). Taking age and ethnicity into account, our group had more chronic respiratory and gastrointestinal problems than the comparable male population of Oahu in 1979, but fewer such problems than active shipyard workers elsewhere. These problems related primarily to current smoking status and secondarily to the length of asbestos exposure. Health care was available, but former workers used it less than retirees, despite having more symptoms. Very few abnormalities were reported by the subjects on their chest X-rays, pulmonary function tests, and sputum cytology performed elsewhere. These findings are compared to those of other shipyards, and support the hypothesis that the biological effects of asbestos exposure are generally mild in Hawaii.

Morbidity in retired coke oven plant workers.

The effect of past occupational exposure on morbidity was studied in 354 coke oven workers in Lorraine Collieries (France) who retired between 1963 and 1982, and were still alive in 1988; 96% of them participated in this study. Occupational exposure to respiratory hazards during the working life was retraced for each subject. No significant association between the occupational exposure and the frequency of ischemic cardiopathies, arterial hypertension, gastro-duodenal ulcers, and respiratory symptoms was revealed. However, subjects who had worked on the Ovens, in the Workshops, and in the Byproducts showed a prevalence of arterial hypertension significantly higher than the non- or slightly exposed subjects. The healthy worker effect phenomenon, the exclusion of deceased subjects, and the small size of this retiree population may conceal possible differences between exposure groups.

Decreases of CD4- and CD8-positive T lymphocytes in retired chromate workers.

To investigate the effects of chromates on the human immune system, we measured total T lymphocytes and their two major subpopulations (CD4+ and CD8+ T lymphocytes) in the peripheral blood of 19 retired male workers who had been exposed to chromate at a chemical plant. The results indicated that both CD4+ and CD8+ T lymphocytes were significantly decreased, resulting in decreases in total T lymphocytes and total lymphocytes.

Effect of recall period on the reporting of occupational injuries among older workers in the Health and Retirement Study.

Studies of injury morbidity often rely on self-reported survey data. In designing these surveys, researchers must chose between a shorter recall period to minimize recall bias and a longer period to maximize the precision of rate estimates. Using data from the Health and Retirement Study, which employed a recall period of 1 year, we examined the effect of the recall period on rates of occupational injuries among older workers as well as upon rate ratios of these injuries for nine risk factors. We fit a stochastic model to the occupational injury rates as a function of time before the interview and used this model to estimate what the injury rates would have been had we used a 4-week recall period. The adjusted occupational injury rate of 5.9 injuries per 100 workers per year was 36% higher than the rate based on a 1-year recall period. Adjustment for recall period had much less effect on rate ratios, which typically varied by < 10%. Our work suggests that self-reported surveys with longer recall periods may be used to estimate occupational injury rates and also may be useful in studying the associations between occupational injuries and a variety of risk factors.

Health-promoting behaviors among adults with type 2 diabetes: findings from the Health and Retirement Study.

BACKGROUND: Type 2 diabetes has an enormous impact on the health care system and individuals. Dietary habits, exercise, weight management, and smoking status are critical to management and prevention of complications. This study describes the prevalence of these behaviors and their change over time in a national sample of adults with type 2 diabetes. The relationships between behavior change and sociodemographic and health status measures are explored. METHODS: Data are from the first and third longitudinal waves of the Health and Retirement Study. Surveys were conducted face-to-face or via telephone in 1992 and 1996. RESULTS: The sample consisted of 733 persons with type 2 diabetes, ages 50-62. The most common behaviors were being on a special diet (79.6%), and not smoking (76.6%). Sixty-six percent were engaged in some physical activity, and 58.4% were trying to lose weight. Reports of being on a special diet, trying to lose weight, and exercising all diminished over time. CONCLUSIONS: The prevalence of these behaviors is disappointing. Worse, they declined over the 4-year period. A better understanding of factors contributing to a person's decision to begin or discontinue health-promoting behaviors is needed to plan effective supportive or preemptive interventions.

Evaluation of serum type III procollagen peptide as an exposure marker in retired coal workers.

Serum type III procollagen peptide (PIIIP), a degradation product of the type III collagen precursor, has been put forward as an exposure marker for mineral dust. We evaluated PIIIP levels as a marker of exposure to and effects of coal dust in retired coal miners (n = 104). To this end: (a) the individual cumulative dust exposure was calculated from job-exposure matrices, and (b) in addition to routine chest radiography (CR) of all miners according to the criteria of the International Labour Organisation (ILO), a subgroup (n = 46) was screened by high-resolution computed tomography (HRCT). Profusion score (CR and HRCT) tended to increase with cumulative dust exposure, even in the absence of CR evidence for pneumoconiosis (i.e. CR < or = 0/1, n = 35). In contrast to our previous findings in active miners, PIIIP levels were not increased in miners as compared with non-dust-exposed controls (n = 29), and no differences were observed between miners without (ILO = 0/0) and miners with coal workers' pneumoconiosis (CWP; ILO > or = 0/1). No trend in PIIIP versus pneumoconiosis stage was present, either by CR or by the more sensitive HRCT score. PIIIP was also unrelated to any lung function parameter (FEV1, FVC, impedance, diffusion capacity). Age, medication, medical history and smoking habits had no significant effect on PIIIP levels. In the miners with CWP (i.e. ILO > 0/0, n = 28) a significant negative correlation was present between PIIIP values and (log) cumulative dust exposure. This decrease in serum PIIIP levels with increasing cumulative exposure may be due to chronic adaptive changes in type III collagen deposition and/or breakdown. Other relations between exposure and PIIIP were not observed. In conclusion, the present findings do not support the use of serum type III procollagen peptide as a marker of exposure to and (early) interstitial or respiratory effects of coal dust.

Disability trends in gender and race groups of early retirement ages in the USA.

OBJECTIVES: To analyse disability trends over the 1980s-1990s in gender and race groups of early retirement ages in USA. METHODS: Disability trends for white and black males and females aged 65-69 and 70+ are analysed using the 1982-1999 NLTCS. Disability is analysed at three levels (instrumental activities of daily living (IADL), activities of daily living (ADL), and institutionalisation). RESULTS: 1) A larger increase in proportions of non-disabled blacks aged 65-69 compared with whites and males compared with females. 2) Differences in disability trends among gender and race groups. 3) A faster absolute decline in non-institutionalised disabled aged 65-69. 4) A larger absolute decline and a smaller relative decline in proportions of disabled aged 70+ compared with 65-69. 5) A significant decrease in the proportion of ADL disabled blacks and an increase of ADL disabled white females in the age group 70+. CONCLUSIONS: Americans aged 65-69 years manifest a significant improvement in health over the 1980s-1990s but the dynamics differs in gender and race groups. Possible reasons for these differences are discussed.
