The social and medical causes of occupational tuberculosis were analyzed by using the results of questionnaire surveys in 300 workers of tuberculosis controlling service. Low salaries, high working load, unbalanced nutrition, poor rehabilitation on vacation are the most important risk factors leading to high rates of both somatic and occupational morbidity in the staff of antituberculosis service.
Hybridization with cDNA arrays was used to obtain expression profiles of 263 protein-tyrosine kinase (PTK), protein-tyrosine phosphatase (PTP), dual-specific phosphatase (DuSP), and other genes for the normal prostate tissue, primary prostate carcinomas (PC) of 84 patients, 7 xenografts, and 5 carcinoma cell lines. Analysis of 96 profiles revealed eight clusters of genes coexpressed in PC (coefficient of correlation r > 0.7). According to the known functions of their genes, the clusters were designated as proliferating-cell (CDC42, TOP2A, FGFR3, MYC, etc.), neoangiogenesis and blood-cell (LCK, VAV1, KDR, VEGF, MMP9, SYK, PTPRS, and FLT4), invasion-1 and invasion-2 (ADAM17, TRPM2, DUSP6, VIM, CAV1, CAV2, JAK1, PTPNS1, FYN, and PDGFB), HER2, and PSA/PSM/HER3. Basing on expression profiles of 66 genes, a molecular classification of PC was constructed and allowed discrimination between PC and cell lines or xenografts at 98.9% probability. The results suggested that, along with PSA, PSM (FOLH1), kallikrein-2, and a-2-macroglobulin, cell signaling genes EGFR, HER2, HER3, TOP2, KRT8, KRT18, VEGF, CD44, VIM, CAV1, and CAV2 may serve as diagnostic and prognostic markers in PC. The HER2, VEGF, and CD44 genes and the MMP and ADAM families were assumed to be promising targets for inhibitors of PC cell proliferation and metastasis.

In 2002 Catholic Charities USA and the Catholic Health Association sponsored a study assessing the state of collaboration in Catholic ministries across the United States. The study was conducted by Health Systems Research, Inc., and was funded in part by a grant from SC Ministry Foundation. As part of the study, researchers visited give sites (St. Petersburg/Tampa, FL; Cleveland; Wichita, KS; Orange County, CA; and Albany, NY) to learn what makes for successful collaboration. This is the second in a series of articles for Health Progress highlighting the findings from this study, which will become available later this year.
