Background  

Physical activity has been associated with a decreased risk for breast cancer. The biological mechanismn(s) underlying the association between physical activity and breast cancer is not clear. Most prominent hypothesis is that physical activity may protect against breast cancer through reduced lifetime exposure to endogenous hormones either direct, or indirect by preventing overweight and abdominal adiposity. In order to get more insight in the causal pathway between physical activity and breast cancer risk, we designed the Sex Hormones and Physical Exercise (SHAPE) study. Purpose of SHAPE study is to examine the effects of a 1-year moderate-to-vigorous intensity exercise programme on endogenous hormone levels associated with breast cancer among sedentary postmenopausal women and whether the amount of total body fat or abdominal fat mediates the effects.  相似文献

Thirty short and slowly growing children with normal plasma growth hormone (GH) responses to standard provocation tests were randomly assigned to either a group (n = 20) undergoing treatment with methionyl GH (somatrem), 2 IU per m2 body surface s.c. daily, or a control group (n = 10). Twelve out of 18 children who completed the first year of treatment showed a height velocity increment of more than 2 cm/year. The mean (SD) growth velocity of the treatment group increased by 3.0 (1.9) cm/year over the first year, compared with -0.2 (0.7) cm/year in the control group. Neither parameters of endogenous GH secretion nor plasma IGF-I levels showed a significant correlation with the growth response. Of the auxological variables studied, pre-treatment growth velocity (r = -0.8) and the short-term height velocity increment (r = 0.7-0.9) showed significant correlations with the growth response in the first year of treatment. Somatrem therapy was without side effects, except in one child who developed anti-GH antibodies in combination with a poor growth response.  相似文献

Methionyl growth hormone (somatrem) in a daily dosage of 4 IU/m2 body surface area was administered to 16 girls with Turner syndrome. Low dose ethinyl estradiol (0.1 microgram/kg body weight) was added in girls aged 13 years or more. Mean (SD) height velocity increased from 3.4 (0.9) to 7.2 (1.7) and 5.3 (1.3) cm/year in the first and second year, respectively. Bone age advanced 1.8 years over 2 years and predicted adult height was increased. Apart from the occurrence of anti-GH antibodies there were no side effects. In conclusion, somatrem is an efficacious and safe therapy for short stature in Turner syndrome over a period of 2 years. Longer follow-up is needed before conclusions about its effect on final height can be drawn.  相似文献

We report a case of a 39-year-old male with bipolar affective disorder who was admitted to hospital with an intentional acute lithium intoxication resulting in renal insufficiency. The patient had previously been treated with lithium, risperidone, fluoxetine and lorazepam, and successfully titrated to lithium levels of 0.7 mmol/l. After overdosing, the lithium level was 5.89 mmol/l and haemodialysis was initiated. A full pharmacokinetic time profile of lithium was obtained. After successful haemodialysis treatment, lithium levels recovered below toxic levels of 1.5 mmol/l in 53 hr. Without intervention non-toxic levels were not expected to have been reached within 6 days, based on computer simulation of predialysis levels. The patient was discharged 6 days after admission without residual symptoms. It was concluded that the lithium intoxication resulted from a combination of lithium overdose and subsequent renal insufficiency due to the overdose. A possible fluoxetine-risperidone interaction was not considered clinically apparent.  相似文献

OBJECTIVES: In East Germany, uranium mining was performed on a large scale for approximately 45 years (1946-1990). In particular, the poor working conditions during the post-war years until 1955 led to a high level of occupational diseases. The present study gives an overview of the occurrence of occupational diseases during the mining period as well as after uranium mining was stopped in 1990. METHODS: The number of occupational diseases which occurred during the mining period was calculated from the files of the former Wismut SDAG. Although exposure to uranium ceased after 1990, new cases of occupational diseases were recognized after that date. These were recorded by the German Federation Of Institutions For Statutory Accident Insurance And Prevention (HVBG). RESULTS AND CONCLUSIONS: Today, more than 35,000 cases of occupational diseases are known, and many more are expected. About two-thirds of them are lung diseases: 16,376 cases of silicosis/silicotuberculosis and 7,695 cases of bronchial carcinomas. The increase in the number of recognized occupational diseases is shown and discussed against the background of changes in criteria for recognition and in working conditions as well as the duration of the latency period.  相似文献

Spoligotyping was used for genotyping of 238 M. tuberculosis cultures isolated from 302 patients with pulmonary tuberculosis living in the north-west of Russia, including those in Saint Petersburg, in 1998-2001, and the M. tuberculosis strains H37Rv, M. bovis, and M. bovic BCG and M. tuberculosis in the specimens painted for microscopy. The quality of spoligotyping was high and similar to that when DNA from the cultured mycobacteria and slide scrapes. The findings were compared with the data available in the International database. There was heterogenicity in the microbial population: the clinical strains showed 58 (RO-R57) types of profiles, of them 56% were revealed in single cases. The spoligotype RO(1; S1) was found in 153 (51%) patients. This spoligotype is predominant in the world and characteristic of polyresistant high-transmissive strains of the genetic family Beijing. The spoligotypes R24 (251), R14 (252), and R8 (253) first described by the authors are now encountered only in Russia. To extend the Russian database that contains M. tuberculosis spologotyping profiles from different regions will promote the improvement of an epidemiological surveillance system and tuberculosis control programmes not only within administrative territorial entities, but also within the whole country.  相似文献
