Nation-wide research on mental health problems amongst men and women during the transition from employment to retirement is limited. This study sought to explore the relationship between retirement ...and mental health across older adulthood, whilst considering age and known risk factors for mental disorders. Data were from the 1997 National Survey of Mental Health and Well-being, a cross-sectional survey of 10,641 Australian adults. The prevalence of depression and anxiety disorders was analysed in the sub-sample of men (
n
=
1928
) and women (
n
=
2261
) aged 45–74 years. Mental health was assessed using the Composite International Diagnostic Instrument. Additional measures were used to assess respondents’ physical health, demographic and personal characteristics. The prevalence of common mental disorders diminished across increasing age groups of men and women. Women aged 55–59, 65–69, and 70–74 had significantly lower rates of mental disorders than those aged 45–49. In contrast, only men aged 65–69 and 70–74 demonstrated significantly lower prevalence compared with men aged 45–49. Amongst younger men, retirees were significantly more likely to have a common mental disorder relative to men still in the labour force; however, this was not the case for retired men of, or nearing, the traditional retirement age of 65. Men and women with poor physical health were also more likely to have a diagnosable mental disorder. The findings of this study indicate that, for men, the relationship between retirement and mental health varies with age. The poorer mental health of men who retire early is not explained by usual risk factors. Given current policy changes in many countries to curtail early retirement, these findings highlight the need to consider mental health, and its influencing factors, when encouraging continued employment amongst older adults.
The decline in heart-beating brainstem dead organ donors has necessitated the search for other organ sources. In the field of renal transplantation one alternative source currently available, but ...little used, is that of kidneys from non-heart-beating donors (NHBD). Reticence to use NHBD kidneys is in part due to concerns over the effect that warm ischemic may have subsequent graft function. Presented here are the results of the NHBD renal transplants at the Leicester transplant unit, and compared with matched heart-beating donor transplants as a case control analysis.
In order to analyze any differences in graft performance between the two organ sources, the confounding effect of other variables known to influence the outcome of renal transplantation was minimized by matching NHBD and HBD transplants for the following criteria: donor age and sex, first or re-transplant, anastomosis and cold times, tissue match and PRA sensitisation. Transplant performance was assessed primarily by graft survival, the statistical evaluation of which was by log rank analysis of Kaplan-Meier curves.
72 NHBD and 192 HBD transplants were performed over an eight year period. Of the 192 HBD transplants, 105 matched one or more of the NHBD by the criteria outlined above, and thus constituted the control group for comparison. There was no significant difference in overall graft survival between the two groups. The 5 year survival for the NHBD was 73% compared with 65% for HBD kidneys. When death with a functioning graft is treated as censored data, then these figures become 75% and 81% respectively, again without statistical significance.
NHBD kidneys are a valuable additional source of organs for transplantation, with long-term survival, comparable to transplants from HBD.
Despite growing interest and concern about men's mental health during the perinatal period, we still do not know whether men are more vulnerable to mental health problems during this time. The ...current study is one of the first to use longitudinal, population-based data to investigate whether becoming an expectant and/or new father is associated with increases in psychological distress. We analyzed 10 waves of data collected annually (from 2001 to 2010) from the nationally representative Household, Income, and Labour Dynamics in Australia (HILDA) Survey. Over this time, 349 men were identified as new fathers (first child aged <1 year), and 224 of these men had been identified as "expectant fathers" during the previous wave. A total of 1,658 men remained "never fathers." Psychological distress was measured using the 5-item Mental Health Inventory before the partner's pregnancy, during the partner's pregnancy, and during the first year of fatherhood. Longitudinal mixed models showed no significant increase in psychological distress as a function of expectant or new fatherhood; instead, some improvement in mental health was observed. The finding suggests that expectant and new fathers are not at greater risk of poor mental health. Future epidemiologic research should continue to identify those men who are most (and least) at risk during the perinatal period in order to target resources and assistance most effectively.
Paid work is related to health in complex ways, posing both risks and benefits. Unemployment is associated with poor health, but some jobs may still be worse than no job at all. This research ...investigates that possibility. We used cross-sectional survey data from Australians aged 40–44 (
N
=
2497
). Health measures were depression, physical health, self-rated health, and general practitioner visits.
Employees were classified according to their job quality (strain, perceived job insecurity and marketability). Employee health was compared to people who were unemployed, and to people who were not in the labour force.
We found that unemployed people reported worse health when compared to all employees. However, distinguishing in terms of employee's job quality revealed a more complex pattern. Poor quality jobs (characterized by insecurity, low marketability and job strain) were associated with worse health when compared to jobs with fewer or no stressors. Furthermore, people in jobs with three or more of the psychosocial stressors report health that is no better than the unemployed.
In conclusion, paid work confers health benefits, but poor quality jobs which combine several psychosocial stressors could be as bad for health as being unemployed. Thus, workplace and industrial relations policies that diminish worker autonomy and security may generate short-term economic gains, but place longer-term burdens on the health of employees and the health-care system.
While tissue dysfunction is a well-recognized consequence of diabetes mellitus in aged people, the underlying mechanisms are poorly understood. Daily (VCE) supplementation of vitamins C and E can be ...beneficial to diabetic aged animals in reducing free radical production. The aim of this study was to investigate whether dietary VCE supplementation modulates oxidative stress and antioxidant redox systems in streptozotocin (STZ)-induced aged diabetic rats. Thirty aged rats (18 - 20 months) were randomly divided into three groups. The first group acted as a control and the second group was diabetic. VCE-supplemented feed was given to aged, diabetic rats, constituting the third group. Diabetes was induced using a single dose of intraperitoneal STZ. On the 21(st) day after STZ dosage, blood and tissue samples were taken from all animals. Glutathione peroxidase activity in liver, erythrocytes, muscle, and testes; catalase activity in plasma and erythrocytes; reduced glutathione levels in plasma; vitamin E concentration in plasma, liver, and muscle; b-carotene concentration in brain; and high-density lipoprotein (HDL)-cholesterol levels in plasma were lower in the diabetic group than in the control group. Lipid peroxidation (LP) levels in plasma, liver, brain, and muscle, and alanine aminotransferase (ALT), aspartate aminotransferase (AST), triacyglycerols, and total and low-density lipoprotein (LDL)-cholesterol values in plasma were higher in the diabetic group than in the control group. The LP, enzyme, vitamin, and lipid profile values levels were mostly restored by VCE treatment. Liver and testis weights did not change by diabetic status and VCE supplementation, although body weight was lower in the diabetic group than in the control group. In conclusion, brain, liver, and testes tissues seem most sensitive in aged diabetic rats to oxidative stress. We observed that VCE supplementation relieves oxidative stress in the blood and tissues of diabetic aged rats by modulating the antioxidant system and lipid profile.
Purpose: The purpose of this article was to investigate the role of control beliefs in mediating the relationship between driving cessation and change in depressive symptoms in a population-based ...sample of older adults. Design and Methods: We report results from a prospective, community-based cohort study that included two waves of data collected in 1992 and 1994. Participants consisted of 700 men and women aged 70 and older, including 647 drivers and 53 participants who ceased driving between baseline (1992) and follow-up (1994). Participants took part in interviews that included assessments of driving status, sociodemographic characteristics, self-rated health, sensory function, depressive symptoms (through the Center for Epidemiologic Studies–Depression scale), and expectancy of control. Using multilevel general linear models, we examined the extent to which driving status, expectancy of control, and relevant covariates explained change in depressive-symptom scores between baseline and follow-up.&!ensp;Results: Driving cessation was associated with an increase in depressive symptoms from baseline to follow-up. The higher depressive-symptom scores of ceased drivers relative to those of individuals who remained drivers at both waves was partly explained by a corresponding decrease in the sense of control among ceased drivers, and increased control beliefs among drivers. Implications: Interventions aimed at promoting the maintenance of personal agency and associated control beliefs could be protective against the negative psychological concomitants of driving cessation.
Isolates of Pythium irregulare were sampled from seven cereal crops throughout South Australia to determine the extent of genetic diversity within this pathogen and the scale of genetic ...differentiation among populations. Data derived from 29 individual restriction fragment length polymorphism (RFLP) loci differentiated 54 DNA fingerprints among the 92 isolates analysed. Some isolates had two alleles at several RFLP loci and were scored as heterozygous. One such isolate was selfed in vitro and segregation ratios in the progeny were not significantly different from those expected for allelic variation in a diploid. These data provided evidence that outcrossing occurs within P. irregulare and may contribute to the high level of genetic variation within the species (DT = 0·502). Allelic frequencies were significantly different among all seven populations and GST values showed significant genetic differentiation between populations. The average genetic identity among populations was low and hierarchical cluster analysis provided no clear evidence that populations formed geographically related groups. These analyses indicate low levels of interpopulation gene flow within P. irregulare and imply that population differentiation results from genetic drift.
Objective
To determine whether the change from the Leadbetter‐Politano technique to a stented extravesical technique for the vesico‐ureteric anastomosis in renal transplantation has altered the ...incidence of urological complications.
Patients and methods
Data were retrieved from a prospective computerized database and by case‐note review on 248 consecutive renal transplants performed between January 1990 and June 1996. The characteristics of the donor, recipient and organ were noted, together with the technique used for the vesico‐ureteric anastomosis and the occurrence of major and minor urological complications.
Results
The Leadbetter‐Politano technique was used in 140 transplants and the stented extravesical technique in 108. There were no significant differences in the donor, recipient or organ characteristics between the groups. The stented extravesical technique was associated with a significantly lower rate of major complications (<2%) and clinically significant haematuria than with the Leadbetter‐Politano technique.
Conclusion
Changing from the Leadbetter‐Politano technique to a stented extravesical technique for the vesico‐ureteric anastomosis has been a major factor in reducing the incidence of urological complications in our transplant practice.
