Based on traditional quality of life scales, it has been suggested that known side-effects of prostate cancer treatment do not influence the quality of life. The present authors have developed an alternative approach to quality of life assessment applying epidemiological methods. Using a self administered questionnaire, we investigated 431 prostate cancer patients and an age stratified sample of 435 randomly selected men. Patients reporting any level of distress due to waning sexual functions (66%) or urine or bowel symptoms (38%), reported a lower psychological well-being compared to patients not reporting these symptoms or patients not distressed by their symptoms. Our results stress that an intact sexual and urinary and bowel functions are important for the quality of life among elderly men with or without prostate cancer. 相似文献
Introduction: Fibroblast activation protein-α (FAP-α) belongs to the family of prolyl-specific serine proteases. FAP-α displays both exopeptidase and endopeptidase/gelatinase/collagenase activities. FAP-α protein and/or activity have been associated with fibrosis, inflammation and cancer, but the protein is undetectable in most normal tissues. FAP-α is selectively expressed at sites of tissue remodeling and repair and enhances tumor progression, suggesting that this protease may be a therapeutic target to treat human disorders associated with fibrotic dysregulation.
Areas covered: In this review, we summarize the mechanisms driving tissue fibrosis and describe some of the enzymes involved in fibrosis, concentrating on FAP-α. We describe its enzymatic properties, discuss the tools developed to control its activity and the problem of selectivity toward the other proteases of the family and outline its potential biological substrates. We also consider non-enzymatic functions of this protein and suggest that repression of FAP-α expression may represent therapeutic options.
Expert opinion: Questions remain regarding the biological functions of FAP-α, either dependent or independent of its enzyme activity. However, as progress is underway to develop FAP-α-specific inhibitors and therapeutic antibodies, its role in diseases associated with fibrosis is starting to emerge, ultimately leading to novel therapeutic options for inflammatory and oncologic diseases. 相似文献
Sepsis-induced cardiogenic shock in combination with severe acute respiratory failure represents a life-threatening combination that is often refractory to the conventional methods of treatment. We describe the case of a 33-year-old patient who developed acute cardiovascular collapse and ARDS secondary to superinfection of Panton–Valentine leukocidin—positive Staphylococcus aureus and H1N1 pneumonia who underwent successful combination therapy for severe sepsis-related cardiomyopathy and respiratory failure using extracorporeal membrane oxygenation and cytokine adsorption therapy. 相似文献
BACKGROUND: To date, no murine models have been reported to show the induction of both antigen-specific IgE and nasal eosinophilia, two of the major hallmarks of allergic rhinitis, after local sensitization in the absence of adjuvants, a phenomenon which reflects natural exposure. In this report, we attempted to establish a murine model representing an initiation of allergic rhinitis. METHODS: BALB/c, CBA/J, and C57BL/6 mice were sensitized intranasally to Schistosoma mansoni egg antigen (SEA) solely. After repeated sensitization, serum Ab titers, nasal eosinophilia, and cytokine production by nasal lymphocytes were determined. RESULTS: BALB/c mice produced SEA-specific IgE after repeated sensitization. High-dose sensitization to SEA induced IgE production in CBA/J mice, while C57BL/6 mice did not show the production throughout the period observed, suggesting that IgE production was regulated genetically. BALB/c mice also exhibited nasal eosinophilia after the nasal challenge. In addition, nasal lymphocytes sensitized with SEA intranasally produced significant amount of IL-5 in vitro. CONCLUSIONS: These results suggest that intranasal sensitization with SEA in the absence of adjuvants induces a Th2 immune reaction, reflecting the hallmarks of the initiation of allergic rhinitis both in vivo and in vitro, which is genetically regulated. 相似文献
