Abstract Background Tibetan highlanders have adapted to hypoxic environments through the development of unique mechanisms that suppress an increase in hemoglobin (Hb) concentration even in high-altitude areas. Hb concentrations generally decrease with increasing age. However, in the highlands, chronic altitude sickness is known to occur in the elderly population. To investigate how aging in a hypoxic environment affects Hb levels in Tibetan highlanders, we focused on the Mustang people, who live above 3500 m. We tried to clarify the pure relationship between aging and Hb levels in a hypoxic environment. Results We found that the Hb concentration increased with increasing age in females but not in males. Multivariate analysis showed that age, pulse pressure, the poverty index, and vascular diameter were strongly correlated with the Hb concentration. Conclusions We found unique Hb dynamics among female Tibetan highlanders. As seen in these Hb dynamics, there may be sex-based differences in the adaptive mechanism in Tibetan highlanders.

ABSTRACTMicro-data from a 1984 survey of adult education in Canada are used in the study. The data for persons 65 years of age and over are analysed using probit techniques. Prior level of education is found to be of considerable importance in determining the probabilities that elderly people will make use of adult education facilities. It is argued that future elderly population cohorts will have higher average education levels than present ones and that their members will therefore be more likely to take courses. Projections of increases in course enrolment by persons 65 and over are made for the next quarter century, based on the results of the probit analysis and projections of the population.

ABSTRACTTo the existing ways of categorizing elderly individuals we here add a reasonably objective approach using recent survey data and statistical methods of multivariate analysis. The groupings obtained have been surprisingly clear-cut, so that simple rules can be devised for discriminating between clusters. We suggest this analysis as a useful way of gleaning information about elderly people, information which may help in the efficient allocation of services.

Abstract. This study examines the psychometric properties of the IQCODE and its applicability in the Iranian elderly population. A group of 95 elderly patients with at least 4 years of formal education who fulfilled the criteria of DSM-IV-TR for dementia were examined by the MMSE and the AMTs. The Farsi version of the IQCODE was subsequently administered to their primary caregivers. Results showed a significant correlation ( p = .01) between the score of the questionnaire and the results of the MMSE ( r = −0.647) and AMTs ( r = −0.641). A high internal reliability of the questionnaire was confirmed by Cronbach’s alpha coefficient (α = 0.927) and test-retest reliability by correlation coefficient ( r = 0.81). This study found that the IQCODE has acceptable psychometric properties and can be used for evaluating the cognitive state in the elderly population of Iran.

Sacral insufficiency fractures (SIFs) are a cause of debilitating low back pain that is often difficult to diagnosis and manage. The diagnosis of SIF is often delayed due to inaccurately attributing symptoms to spondylosis, which is a commonly present in the elderly population where SIFs are most prevalent. Historically, treatment consisted of medical management and open reduction internal fixation reserved for severe cases. However, percutaneous sacroplasty has emerged as a minimally invasive treatment option which provides early pain relief without significant complications. The objective of this article is to raise awareness of SIFs and percutaneous sacroplasty as an effective and safe treatment method.

Geriatric syndromes consist of common clinical conditions affecting the elderly population. They lead to multiple, interacting medical and social deficits that increase the risk of adverse health outcomes, including dependence, institutionalization and also death. Research over the last few decades, in this area of medicine, has led to evolution of newer syndromes that pose a greater challenge to the physician. The present review aims to provide a synopsis of some of the newer syndromes like frailty, osteosarcopenia, sleep disorders and oropharyngeal dysphagia that have emerged in geriatric literature in recent times.
