Mortality and suicide rates of involuntarily committed patients

The mortality and suicide rates for involuntarily committed patients in Denmark are presented. Two cohorts of psychiatric patients committed to a mental hospital from January 1, 1971 to December 31, 1975 (8322 people) and January 1, 1981 to December 31, 1985 (5253 people) have been followed. The standard mortality rate (SMR) in relation to the total Danish population were 4.9 (4.5–5.4) and 5.2 (4.7–5.8), respectively, for the two cohorts, during the first year after involuntarily commitment to a mental hospital. During the same period, the SMR for suicide among the committed patients were 44.9 (37.1–53.9) and 30.9 (24.2–38.9), respectively. The crude suicide rates among the committed patients during the first year after the commitment were 14.3 and 14.0, respectively, per 1000 years, unchanged between the cohorts. Short length of stay in hospital (< 14 days), a nonpsychotic main diagnosis, male sex, and age 35 years or more were equally related to high risk of suicide in the 1971 cohort as evaluated to proportional hazard methods (Cox regression), and short length of stay and commitment on the danger indication provided the most information in relation to high suicidal risk in the 1981 cohort. Methodological problems and the reasons for the results are discussed.     

Lysosomal abnormalities in degenerating neurons link neuronal compromise to senile plaque development in Alzheimer disease

Antibodies to the lysosomal hydrolases, cathepsins B and D and β-hexosaminidase A, revealed alterations of the endosomal-lysosomal system in neurons of the Alzheimer disease brain, which preceded evident degenerative changes and became marked as atrophy, neurofibrillary pathology, or chromatolysis developed. At the earliest stages of cell atrophy, hydrolase-positive lysosomas accumulated at the basal pole and then massively throughout the perikarya and proximal dendrites of affected pyramidal neurons in Alzheimer prefrontal cortex and hippocampus, far exceeding the changes of normal aging. Secondary lysosomes as well as tertiary residual bodies (lysosomes/lipofuscin) increased implying stimulated, autophagocytosis and lysosomal system activation. Less affected brain regions, such as the thalamus, displayed similar though less extensive alterations. Certain thalamic neurons exhibited a distinctive lysosome-related abnormality characterized by the presence of cell surface blebs of varying size and number filled with intense hydrolase immunoreactivity. At more advanced stages of degeneration in still intact neurons, hydrolase-positive lipofuscin, particularly in the form of abnormal large aggregates, nearly filled the cytoplasm. Similar lipofuscin aggregates were oberved in abundance in the extracellular space following cell lysis and were usually associated with deposits of the β-amyloid protein. Degenerating neurons and their processes were the major source of these aggregates within senile plaques which contained high concentrations of acid hydrolases. We have shown in previous studies that these lysosomal hydrolases in plaques are enzymatically-active. The persistence of lysosomal structures in the brain parenchyma after neurons hyve degenerated is a striking and potentially diagnostic feature of Alzheimer disease which has not been observed, to our knowledge, in other degenerative diseases. The lysosomal response in degerating Alzheimer neurons represents a probable link between an early activation of the lysosomal system in at-risk, normal-appearing neurons and the end-stage contribution of lysosomes to senile plaque formation of emphasizes a slowly progressive disturbance of the lysosomal system throughout the development of Alzheimer disease.

The social sciences and successful aging: Issues for Asia–Oceania

Aim:   This paper presents social science understandings of successful aging for a broad audience in multidisciplinary gerontology in Asia–Oceania.
Methods:   The international literature on social science aspects of successful aging is reviewed with a focus on Asia and social improvement.
Results:   New positive approaches to aging research are identifying opportunities for maintaining capacities and well-being over the life course. Successful aging, productive aging, and active aging are key concepts. Increasing life expectancy and fertility control are major social achievements that underpin population aging as the mainstream social transformation facing the world. Asia will be at the forefront of this change and the consequences will vary greatly between cultures, nations, and subgroups within them. Older people generally maintain good quality of life and the capacity to 'age well' is influenced by life-long maturation and emotional, social, and economic resources. Good health can be enhanced through positive actions such as physical activity, good nutrition, and not smoking. Mental capacities can also be improved and maintained throughout old age. In advanced old age, the 'fourth age', the focus turns to ameliorating the effects of loss and to maintaining dignity.
Conclusions:   The social sciences contribute knowledge useful for improving life experiences for older people and aging societies. Population aging is central to national economic development. Public policy and individual action concerning aging can benefit all age groups. To better inform these developments it is important to address the serious shortfall of social science research on aging in the Asia–Oceania region.

Polymorphic distribution of Y-chromosome haplotype and mitochondrial DNA in the Bouyei people in China

In the evolution of humans, many kinds of mutations in the human genome have been accumulated, providing credible genetic evidence for the study of human origins and migrations. The "out-of-Africa" hypothesis of modern human evolution and the genetic origin of the Japanese has come about by studying mitochondrial DNA.l,2 Recently, researchers have recognized the power of Y-chromosome markers in resolving migratory patterns of modern humans as more and more Y-chromosome single nucleotide polymorphism markers have been found. The markers on the nonrecombinant part of the Y-chromosome allows for the reconstruction of intact haplotypes which are probably the best genetic tools to study human migrations. We can analyze the paternal history of some people in different areas by Y-chromosome haplotypes.
