Objective Short-term mortality rates remain high among critically ill human immunodeficiency virus-1 (HIV-1) patients though long-term mortality rates have dropped. Baseline risk factors for short-term mortality have not yet been determined in China. In this paper, we herein describe clinical characteristics, laboratory findings, causes of clinical deterioration, and risk factors associated with mortality among HIV-1 patients within six months after hospital admission. Methods We carried out a prospective study of hospitalized patients in advanced stages of HIV infection. These patients started antiretroviral therapy three or four weeks after admission. Follow-up was conducted for a period of six months. We used a multivariate logistic-regression analysis to identify risk factors associated with mortality. Results A total of 141 patients met our inclusion criteria. The mean age was 41 years. Fever and weight loss were the most common clinical manifestations of advanced HIV disease. Oral candidiasis, tuberculosis, cytomegaloviremia, and pneumocystis pneumonia were the most common opportunistic infections. Significantly decreased CD4+ T-cell counts, hypoalbuminemia, anemia, hyponatremia, as well as elevated C-reactive protein (CRP) and glutamic alanine transaminase levels were common laboratory test abnormalities. The mortality rate was 21.3%. The patients who died were more likely than the survivors to have low CD4+ T-cell counts as well as low creatinine, hemoglobin, albumin, and serum sodium levels while also having longer intervals of fever and higher CRP levels. A multivariate analysis demonstrated that the independent risk factors for mortality were active tuberculosis [odds ratio (OR): 2.681; 95% confidence interval (CI), 1.006-7.142; p=0.049], hyponatremia (OR: 3.027; 95% CI, 1.238-7.401; p=0.015), and being at clinical stage 4 (as defined by the World Health Organization) (OR: 9.492; 95% CI, 1.200-75.065; p=0.033) within the first six months of admission. Conclusion Special consideration should be given to patients who have active tuberculosis, are at clinical stage 4, and present with hyponatremia upon admission as these were found to be important factors associated with mortality within six months of hospital admission in HIV-1 patients.

Many studies have suggested that the intake of soy products may protect against the occurrence of breast cancer because of the considerable amount of isoflavones they contain. To review the results of the observational studies, we performed this meta-analysis of the relevant literature. We searched Medline for reports that examined the association between soyfood consumption (or isoflavone intake) and breast cancer risk from January 1966 to April 2006. The random-effects model was used to estimate the pooled relative risk (RR). Twenty-one independent studies (14 case-control studies and 7 cohort studies) were included in the final analysis. The pooled RR of breast cancer for soyfood intake was 0.75 with a 95% CI of 0.59-0.95. As the main types of soyfood in Japan and China, tofu and miso showed clear protective effects. Isoflavone intake resulted in a 20% decrease in risk (RR=0.81, 95% CI 0.67-0.99). The pooled RR varied little according to study stratification. When the studies published in Japanese and Chinese were added, the inverse associations between soyfood, tofu and breast cancer risk became slightly stronger. The weak association of miso was possibly due to the high concentration of salt in miso soup. In the present analysis, we did not find strong evidence for publication bias in the combination of the studies. This meta-analysis supported the hypotheses that soyfood intake may be associated with a decreased risk of breast cancer due to the isoflavones. Further epidemiological studies need to be conducted with more comprehensive information about the soyfood, and more accurate assessment of the isoflavones.

To assess the effect of milk on the development of 7,12-dimethylbenz(a)anthracene (DMBA)-induced mammary tumors, 48 female Sprague-Dawley rats treated with DMBA were divided into 3 groups and given 1 of 3 test solutions for 20 weeks as their drinking liquid: milk, estrone sulfate solution or tap water. The milk group showed a significantly great incidence (75%) in tumor development compared with the water group (38%) and was comparable to the estrone sulfate group (69%). Mean tumor number per rat in the milk group was significantly higher than that in the water group (p=0.009). We classified the mammary tumors into three histological types: intraductal papilloma, fibroadenoma, and adenocarcinoma. Although the percent of intraductal papilloma and fibroadenoma was almost same among the three groups, malignant tumor was found only in the milk and estrone sulfate groups. In conclusion, our results indicate that milk as well as estrone sulfate promotes the development of DMBA-induced mammary tumors in rat and could be associated with the occurrence of adenocarcinoma.
