Results of a Cross-Sectional Study in 1995: The self-perceived threat of cancer, myocardial infarction, stroke, traffic accidents, diabetes mellitus, AIDS, Alzheimer's Disease and drug abuse was investigated in a survey among a representative sample of Austrians (aged > or = 15 years) in 1995. The most feared disease was cancer (41%), followed by traffic accidents (38%) and myocardial infarction (36%). The disease feared least was drug abuse (6%). Females feared cancer, stroke, diabetes mellitus and Alzheimer's disease significantly more than males. A cluster analysis reveals that respondents who perceive a higher threat by the diseases have low levels of education and live in rural areas. The age distribution of persons who responded with "very threatening" corresponds well with the age-specific prevalence of the disease. Smoking habits, alcohol consumption and body-mass index have no influence on the self-perceived threat of the investigated diseases.

Senile dementia of Alzheimer's type (SDAT) is reported to be less frequent in patients with Diabetes Mellitus. However the, the number of elderly people in still increasing in Japan, an is the incidence of diabetes mellitus, especially in middle-aged and elderly people. Thus, we can expect to encounter more elderly people with diabetes and SDAT. We encountered three patients with diabetes who were treated with insulin and in whom SDAT developed. In all three, control of blood glucose levels gradually worsened, despite increases in the dose of injected insulin. It was later found that they did not inject insulin properly because of SDAT. They lived alone and their dementia was not diagnosed before their admission to the hospital. In its early phase, SDAT can be difficult to diagnose, especially in patients who live alone. SDAT should be considered when the control of blood glucose levels for no apparent reason in elderly patients with diabetes.

The contribution of vascular pathology to the manifestation of dementia and the importance of vascular risk to measures of cognitive function is being increasingly recognized. In particular, confirmation of this risk points towards approaches for prevention in large sections of the population. Information on determinants of incident dementia is increasing, but still relatively few studies of risk have been based on incident cases of dementia in very elderly populations. In this study based on incident cases of dementia in a population aged 75 and over, vascular risks were obtained from informants of the respondents with incident dementia. When compared with controls the factors associated with incident dementia were history of heart attack (odds ratio 2.9), transient ischaemic attacks (4.8), cerebrovascular accidents (3.4), family history of first-degree relatives with dementia (4.0), and occupational exposure to vibrating instruments (1.4). If only Alzheimer's disease, clinically diagnosed, was included, diabetes (1.4) and a history of dementia in first-degree relatives (6.6) emerged. Thus, vascular risk continues to be of importance in the oldest age groups.

The potential therapeutic applications of encapsulated cells are enormous. In the US alone, it has been estimated that nearly half-a-trillion dollars are spent each year to care for patients who suffer tissue loss or dysfunction. Over 6 million patients suffer from neurodegenerative disorders such as Alzheimer's disease and Parkinson's disease, over 14 million patients suffer from diabetes, and millions more from liver failure, hemophilia, and other diseases caused by the loss of specific vital cellular functions. It appears likely that by the end of the decade clinical trials of encapsulated cells to treat many of these diseases will become a reality. The Food and Drug Administration has already authorized studies to evaluate the safety and biological activity of several types of systems. A number of issues will have to be addressed, including the sourcing of raw materials, the design and building of manufacturing facilities, the scale-up and optimization process, storage and distribution of the product, and quality control.

Fermented papaya preparation is a natural health food that has been commercially sold in Japan for 2 years. It is made by yeast fermentation of Carica Papaya Linn. We examined the antioxidant action of the fermented papaya preparation on free radicals and lipid peroxidation. Free radicals have been related with aging and diseases, such as cancer, diabetes and especially in neurological disorders, for example, Parkinson's disease or Alzheimer's disease. A diet including variable antioxidant foods may therefore help to prevent these illnesses. The free radical scavenging activity of the fermented papaya preparation was examined using an electron spin resonance (ESR) spectrometer. Fermented papaya preparation (50 mg/ml) scavenged 80% of hydroxyl radicals (.OH) as spin adducts of spin trap, 5,5-dimethyl-1-pyrroline-N-oxide (DMPO) (5.27 x 10(15)spins/ml) generated by Fenton reagents. The value of IC50 was 12.5 mg/ml. The oral administration of the fermented papaya preparation for 4 weeks decreased the elevated of lipid peroxide levels in the ipsilateral 30 min after injection of iron solution by iron into the left cortex of rats. The fermented papaya preparation also increased superoxide dismutase activity in the cortex and hippocampus of them. These results suggest that the fermented papaya preparation has antioxidant actions and that it may be prophylactic food against the age related and neurological diseases associated with free radicals.

Renal amyloidosis shows symptoms of renal dysfunction due to the deposition of amyloid protein in the kidney. Recently, it was reported that apoptosis plays an important role in the pathogenesis of type-2 diabetes mellitus and Alzheimer's disease of which amyloid deposition is seen in the tissue. We investigated whether or not apoptosis and related factors are observed in renal amyloidosis. In situ nick end labeling (TUNEL) was performed in seven autopsied renal tissues with primary and secondary amyloidosis and 10 autopsied renal tissues without renal disease as the control. The number of TUNEL-positive cells was significantly increased in both the glomeruli and tubulus of the kidney with amyloidosis than in the control. Electron microscopic analysis was performed on one biopsied renal tissue with amyloidosis and six biopsied renal tissues with minor abnormalities as the control. Typical apoptotic cells were observed only in the former. Bax product, an inducer of apoptosis, and Bcl-2 protein, an inhibitor of apoptosis, were examined immunohistochemically in the seven autopsied renal tissues with amyloidosis and 10 autopsied control tissues. Bax was overexpressed in the tubulus and glomeruli of subjects with renal amyloidosis, compared to the normal controls. However, Bcl-2 protein was not detected in the glomeruli in any of the subjects examined. These results indicate that apoptotic cells are increased in number in renal amyloidosis and Bax overexpression may play an important role in this increase.

Hormone replacement therapy (HRT) influences many aspects of health: climacteric symptoms, osteoporosis, cardiovascular disease, breast and endometrial cancer, thrombosis and emboli, and Alzheimer's disease. A decision to use HRT may depend on a woman's individual views of the menopausal transition, the postmenopause and its consequences. It is therefore useful that the health provider inquiries about and discusses these issues in a cultural and family context. Health providers and patients should be thoroughly informed about the symptoms associated with hormonal deprivation, the associated risks of osteoporosis and cardiovascular disease, and the potential of HRT to prevent these afflictions. Recent studies suggest that HRT might be particularly beneficial in women who have an increased risk for cardiovascular disease (because of left ventricular hypertrophy, diabetes mellitus, hypertension or hypercholesterolaemia, or because they smoke) or osteoporosis. In women who are undecided about HRT, a low bone mineral density measurement might help convince them to start using, or to continue using, HRT. There is also a need to discuss with the patient the effect of HRT on cancer risk. In most instances, women can be reassured about the risk of endometrial cancer. The risk of breast cancer should be carefully considered and discussed with each patient before beginning HRT. In most cases, HRT should not be withheld because of fears about breast cancer, because the protective effects of HRT against cardiovascular disease and osteoporosis outweigh the possible increased risk of breast cancer. When HRT is prescribed, individual regiments should be discussed with the patient, who must be warned of the possible adverse effects. In older women, HRT can be started at half the normal dosage and tolerability assessed before increasing the dosage further.

To identify Chinese geneticists' views of ethical issues in genetic testing and screening, a national survey was conducted. Of 402 Chinese geneticists asked to participate, 255 (63%) returned by mail anonymous questionnaires. The majority of respondents thought that genetic testing should be offered in the workplace for alpha-antitrypsin deficiency (95%) and the predisposition of executives to heart disease, cancer, and diabetes (94%); that genetic testing should be included in preemployment physical examinations (86%); that governments should require premarital carrier tests (86%), newborn screening for sickle cell (77%), and Duchenne muscular dystrophy (71%); and that children should be tested for genes for late-onset disorders such as Huntington disease (85%), susceptibility to cancers (85%), familial hypercholesterolemia (84%), alcoholism (69%), and Alzheimer disease (61%). Most believed that partners should know each other's genetic status before marriage (92%), that carriers of the same defective gene should not mate with each other (91%), and that women should have a prenatal diagnosis if medically indicated (91%). The majority said that in China decisions about family planning were shared by the couple (82%). More than half had views that, in China, there were no laws to prohibit disability discrimination (64%), particularly to protect people with adult polycystic kidney disease (57%), cystic fibrosis (56%), or genetic predisposition to other diseases (50%). To some extent, these results might provide a basis for a discussion of eugenics in China, particularly about China's Maternal and Infant Health Care Law (1994).

Since fiscal year 1991, the U.S. Human Genome Project has spent $170.6 million in federal funds to help isolate genes associated with Huntington's disease, amyotrophic lateral sclerosis, neurofibromatosis types 1 and 2, myotonic dystrophy, and fragile X syndrome and to localize genes that predispose people to breast cancer, colon cancer, hypertension, diabetes, and Alzheimer's disease. Now comes the hard part. Biology's 21st century megaproject starts to look relatively manageable compared to another challenge facing the enterprise: sorting out ethical, legal, and social issues associated with using this information. "The Human Genome Project," wrote Senior Editor Barbara Jasny in the October 1 Science editorial, stretches "the limits of the technology and the limits of our ability to ethically and rationally apply genetic information to our lives."

Advanced glycation end products (AGEs) have been implicated in the chronic complications of diabetes mellitus and have been reported to play an important role in the pathogenesis of Alzheimer's disease. In this study, we examined the immunohistochemical localization of AGEs, amyloid beta protein (A beta), apolipoprotein E (ApoE), and tau protein in senile plaques, neurofibrillary tangles (NFTs), and cerebral amyloid angiopathy (CAA) in Alzheimer's disease and other neurodegenerative diseases (progressive supranuclear palsy, Pick's disease, and Guamanian amyotrophic lateral sclerosis/Parkinsonism-dementia complex). In most senile plaques (including diffuse plaques) and CAA from Alzheimer's brains, AGE and ApoE were observed together. However, approximately 5% of plaques were AGE positive but A beta negative, and the vessels without CAA often showed AGE immunoreactivity. In Alzheimer's disease, AGEs were mainly present in intracellular NFTs, whereas ApoE was mainly present in extracellular NFTs. Pick's bodies in Pick's disease and granulovacuolar degeneration in various neurodegenerative diseases were also AGE positive. In non-Alzheimer neurodegenerative diseases, senile plaques and NFTs showed similar findings to those in Alzheimer's disease. These results suggest that AGE may contribute to eventual neuronal dysfunction and death as an important factor in the progression of various neurodegenerative diseases, including Alzheimer's disease.
