Background
Fruit and vegetable intake is low among European children and exposure to TV is negatively associated with the intake of fruit and vegetables. The aim of the present study was to explore exposure to food commercials on TV in nine European countries. Associations between such exposure and intake of fruit and vegetables and possible mediating effects of attitudes toward and liking of fruit and vegetables were assessed. 相似文献72.

Cancer rates are set to increase at an alarming rate, from 10 million new cases globally in 2000 to 15 million in 2020. Regarding the pharmacological treatment of cancer, we currently are in the interphase of two treatment eras. The so-called pregenomic therapy which names the traditional cancer drugs, mainly cytotoxic drug types, and post-genomic era-type drugs referring to rationally-based designed. Although there are successful examples of this newer drug discovery approach, most target-specific agents only provide small gains in symptom control and/or survival, whereas others have consistently failed in the clinical testing. There is however, a characteristic shared by these agents: -their high cost-. This is expected as drug discovery and development is generally carried out within the commercial rather than the academic realm. Given the extraordinarily high therapeutic drug discovery-associated costs and risks, it is highly unlikely that any single public-sector research group will see a novel chemical "probe" become a "drug". An alternative drug development strategy is the exploitation of established drugs that have already been approved for treatment of non-cancerous diseases and whose cancer target has already been discovered. This strategy is also denominated drug repositioning, drug repurposing, or indication switch. Although traditionally development of these drugs was unlikely to be pursued by Big Pharma due to their limited commercial value, biopharmaceutical companies attempting to increase productivity at present are pursuing drug repositioning. More and more companies are scanning the existing pharmacopoeia for repositioning candidates, and the number of repositioning success stories is increasing. Here we provide noteworthy examples of known drugs whose potential anticancer activities have been highlighted, to encourage further research on these known drugs as a means to foster their translation into clinical trials utilizing the more limited public-sector resources. If these drug types eventually result in being effective, it follows that they could be much more affordable for patients with cancer; therefore, their contribution in terms of reducing cancer mortality at the global level would be greater. 相似文献

A laparoscopic method of managing macroscopically benign, unilateral, unilocular, mobile, translucent, and smooth-walled ovarian cysts in women of reproductive age is described. The method requires the cutting of a window in the cyst wall through the laparoscope fenestration. In preference to aspiration at laparoscopy or removal at laparotomy, this method has the advantage of ensuring histologic material as well as permanent drainage by the use of atraumatic surgical technique. Nineteen cysts were fenestrated laparoscopically. Four cysts could not be classified, two owing to lack of histologic material, two owing to malpreparation of the selected cyst tissue. In one case an epithelial cyst--a mucinous cystadenoma, being laparoscopically unsuspected--was fenestrated. One cyst recurred. By observing the above criteria it is possible and tolerably safe to select non-neoplastic cysts, for which fenestration should be reserved. 相似文献

1 This study reports on the pharmacological characterization of ZP120, a novel ligand of the nociceptin/orphanin FQ (N/OFQ) peptide receptor, NOP. ZP120 is a structure inducing probes modified NOP ligand: Zealand Pharma proprietary SIP technology was used to increase the enzymatic stability and half-life of peptide. 2 In vitro, ZP120 mimicked the inhibitory effects of N/OFQ in the electrically stimulated mouse vas deferens, showing however higher potency (pEC(50) 8.88 vs 7.74), lower maximal effects (E(max) 69+/-5% vs 91+/-2%), and slower onset of action. Like N/OFQ, the effects of ZP120 were not modified by 1 micro M naloxone, but they were antagonized by the NOP receptor selective antagonist J-113397 (pA(2) 7.80 vs ZP120, 7.81 vs N/OFQ). 3 In vivo, ZP120 mimicked the effects of N/OFQ, producing pronociceptive effects in the tail withdrawal assay and decreased locomotor activity after i.c.v., but not after i.v. administration in mice. ZP120 elicited similar maximal effects as N/OFQ, but it was about 10 fold more potent and its effects lasted longer. 4 In conclusion, the novel NOP receptor ligand ZP120 is a highly potent and selective partial agonist of the NOP receptor with prolonged effects in vivo. 相似文献

Neoadjuvant chemotherapy has become a standard treatment in the management of locally advanced breast cancer. Patients with earlier-stage disease may also benefit from neoadjuvant treatment in terms of improved rates of breast-conserving surgery and thus better quality of life. Gemcitabine is a pyrimidine analogue that has shown activity in a variety of solid tumors, a good toxicity profile, and nonoverlapping toxicity with other chemotherapeutic agents. Several phase II/III studies are assessing gemcitabine combined with anthracyclines, taxanes, and/or vinorelbine both in the neoadjuvant and metastatic disease settings. This article reviews developments in neoadjuvant use of gemcitabine in combination with anthracyclines and taxanes. Several phase II trials of gemcitabine combined with doxorubicin/epirubicin or with doxorubicin/paclitaxel have been carried out. Preliminary findings demonstrate increased complete response rates and good tolerability of these regimens in patients with breast cancer. 相似文献

BACKGROUND AND PURPOSE: Patient self-assessment of symptom severity provides clinicians and researchers with important information. It is crucial to evaluate the validity of a self-assessment questionnaire in the context of its intended use. The objective of this study was to evaluate the validity of the uro-gynaecological questionnaire (UGQ), a new instrument for patient self-assessment of urological-, genital-, menopausal-, and pain symptomatology in gynaecological cancer patients. MATERIAL AND METHODS: The UGQ was developed after literature review, patient- and expert interviews and pilot testing. From February 1992 to October 1992, 88 gynaecological cancer patients were invited to participate in a validation study after the initiation of their primary radiotherapy or chemotherapy. The method of validation investigated whether patients and researchers interpreted the items of the questionnaire in the same way. The patient's written response before interview was compared with an observer rating of the patient's open-ended audio-taped responses to the same questionnaire, administered as an interview. Qualitative recordings by the observer were made to describe potential misinterpretations. RESULTS: The agreement between the patient's and the observer's ratings was high: the median overall agreement was 0.91 (range 0.71-1.00) and the median kappa was 0.88 (range 0.45-1.00). The quantitative and the qualitative results identified a few minor validity problems; especially, the issue of selective reporting, i.e. some patients only reporting those symptoms they considered relevant for the study, which may lead to systematic errors. CONCLUSIONS: The results strongly suggest that patients interpret the UGQ items as intended, i.e. they are valid. The UGQ is recommended for patient self-assessment of uro-gynaecological morbidity in gynaecological cancer patients. 相似文献

Stability and change in structural social relations as predictor of mortality among elderly women and men 总被引:1,自引:0,他引:1
In a follow-up study of 70–95years old women and men (n = 911) we studied the association between change and stability in three structural aspects of social relations (contact frequency, contact diversity, cohabitation status) from 1986–1990 and mortality after the next four years in 1994. Women aged 70–74years who developed low contact frequency or developed small contact diversity showed significantly higher mortality, adjusted ORfreq: 3.78 (1.08–13.20), adjusted ORdiv: 3.79 (1.24–11.58). Women aged 70–74years with continuously low contact frequency showed an increased mortality compared to women constantly experiencing high contact frequency, adjusted OR: 2.75 (1.04–7.26). A tendency in the same direction for sustained small contact diversity was found, adjusted OR: 1.98 (0.70–5.61). Among women aged 75+ years no impact of frequency and diversity was demonstrated, whereas continuously living alone was a significant predictor of mortality, when compared to women continuously living with somebody, adjusted OR: 2.57 (1.29–5.09). In men, we found a significantly increased mortality among those who developed high contact frequency and developed large contact diversity ORfreq: 3.91 (1.02–14.94) and ORdiv: 6.04 (1.30–28.03). In summary, we found rather larger age differences in the strength of the association between change in structural social relations and mortality. Furthermore, the associations seemed stronger among women than men, which may however mainly be explained by the small number of men in our cohort. 相似文献
