PURPOSE: Although it is widely recognised that educational interventions may be more effective for people with an 'internal' Locus of Control (who believe that life outcomes are controlled by their own characteristics or actions) compared to people with an 'external' Locus of Control (who believe that life outcomes are controlled by external forces such as luck, fate or others), no study has yet assessed the influence of physicians' Locus of Control (LOC) on communication skills learning. This study aims to test the hypothesis that, in a communication skills training program, physicians with an 'internal' LOC would demonstrate communication skills acquisition to a greater degree than those with an 'external' LOC. METHODS: A non-randomised longitudinal intervention study was conducted between January 1999 and April 2001. Sixty-seven volunteer physicians from private and institutional practice in Belgium participated in a learner-centred, skills-focused, practice-oriented communication skills training program. Communication skills changes were assessed in 2 standardised simulated interviews before and after training (one two-person and one three-person interview). Communication skills were assessed using the Cancer Research Campaign Workshop Evaluation Manual. Physicians' LOC was assessed using the Rotter I-E scale. Communication skills changes of the upper and lower third of physicians in respect of their scores on this scale were compared using group by time repeated measures of variance. RESULTS: In the two-person and three-person interviews, changes in the use of open directive questions were more important among physicians with an "internal" LOC compared with changes observed among physicians with an 'external' LOC (P=0.066 and P=0.004, respectively). In the three-person interview, changes in the use of directive questions, assessing functions and moderate feelings stated explicitly were more important among physicians with an 'internal' LOC compared with changes observed among physicians with an 'external' LOC (P= 0.001; P=0.002 and P=0.011 respectively). CONCLUSION: This study shows that physicians' LOC is a psychological characteristic that could influence the efficacy of a communication skills training program. This evidence supports the idea that a psychological characteristic such as 'internal' LOC may facilitate communication skills acquisition through physicians' belief that communication with patients may be controlled by physicians themselves. 相似文献

The aim of this study was to identify factors associated significantly with hospitalised cancer patients' satisfaction with care. Patients were recruited from four geographical/cultural groups, including five European countries and Taiwan. They rated their level of satisfaction by completing the EORTC IN-PATSAT32 questionnaire at home. Additionally, data were collected on the sociodemographic and clinical characteristics and the quality of life of the patients, as well as on institutional characteristics. Of 762 patients recruited, 647 (85%) returned a completed questionnaire. The number of nurses and doctors per bed, institution size, geo-cultural origin, ward setting, teaching/non-teaching setting, treatment toxicity, global health status, participation in clinical trials and education level were all associated significantly at the multivariate level with satisfaction with doctor and nurse interpersonal skills, information provision, availability, and/or overall satisfaction. A number of patient-, institutional- and culture-related factors are associated with the perceived quality of cancer care. Future studies, with appropriate sampling frames and stratification procedures, are needed to better understand cross-national and cross-cultural differences in cancer patient satisfaction. 相似文献

Different methods have been used to evaluate the beneficial effect of varicocelectomy; these include semen parameters and pregnancy rate. Because of high biological variability of semen parameters, sperm functional tests have been considered as an efficient end point in assessment of fertility. Therefore, the aim of this study was to evaluate the effect of varicocelectomy on semen parameters and sperm protamine deficiency in 192 patients. The results of the present study show that all the three semen parameters and percentage of sperms with normal protamine content have improved post-surgery. The cumulative pregnancy rate was 34.6%. Comparing the results of the semen parameters and protamine content between patients whose partner became pregnant to those who did not benefit from varicocelectomy before and 6 months after surgery, show that patients may benefit from varicocelectomy that had higher initial semen density and better sperm morphology prior to surgery. Detailed analyses of sperm morphology, along with aforementioned results reveal that the factors which account for pregnancy difference are: (i) improvement in early events of spermatogenesis, possibly during spermatocytogensis and reduction division; and (ii) late spermiogenesis events. Thus, it can be suggested that patients with low initial sperm count may benefit more from assisted reproductive techniques or varicocelectomy followed by assisted reproduction. 相似文献

BACKGROUND: Transcatheter arterial chemoembolization (TACE) has become one of the most common treatments for unresectable hepatocellular carcinoma. Published studies of TACE report a 5-16% risk of serious complications. Compared with TACE, transcatheter arterial chemoinfusion (TACI) may have similar efficacy and fewer side effects. AIM: To examine the clinical outcomes of TACI. METHODS: We performed a retrospective cohort study of 345 consecutive TACI cases in 165 patients performed at a single United States medical center between 1998 and 2002. Primary outcomes were tumour response and survival rates. RESULTS: Only seven patients were hospitalized for more than 24 h after the procedure, and only three patients had worsening of liver function within 30 days of TACI. Survival was significantly poorer for patients with tumour-node-metastasis (TNM) IV compared to those with TNM I-III and also for patients with Child's class B/C vs. A. Following adjustment for age, gender, ethnicity and aetiology of liver diseases, independent predictors of poor survival were Child's class B/C [Hazard Ratio (HR) = 1.69, P = 0.024] and TNM IV staging (HR = 1.63, P = 0.014). CONCLUSIONS: TACI appears to be safe and effective for unresectable hepatocellular carcinoma with TNM stage I-III; randomized controlled trials are needed to compare TACI to TACE. 相似文献

A scalable method for screening and selection of peptide-specific monoclonal antibodies (mAbs) is described. To identify high affinity anti-peptide mAbs in hybridoma supernatants, antibodies were captured by magnetic affinity beads followed by binding of specific peptides from solution. After timed washing steps, the remaining bound peptides were eluted from the beads and detected by matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) mass spectrometry (MS). This allowed measurement of monovalent interactions of peptides with single antigen binding sites on the antibodies, thus reflecting antibody affinity rather than avidity. Antibodies that were able to bind target peptides from solution phase and retain them during washing for a minimum of 10 min were identified by the strength of the appropriate m/z peptide MS signals obtained. This wash time reflects the minimum peptide dissociation time required for use of these antibodies in several current immuno-mass spectrometry assays. Kinetic analysis of antibody-peptide binding by surface plasmon resonance (SPR) showed that the selected antibodies were of high affinity and, most importantly, had low dissociation constants. This method, called MALDI immunoscreening (MiSCREEN), thus enables rapid screening and selection of high affinity anti-peptide antibodies that are useful for a variety of immunoproteomics applications. To demonstrate their functional utility in immuno-mass spectrometry assays, we used the selected, purified RabMAbs to enrich natural (tryptic) peptides from digested human plasma. 相似文献

The leading candidates for a Transmission Blocking Vaccine (TBV) in Plasmodium vivax parasite are the ookinete surface protein 25 (Pvs25) and Pvs28, which their phase I clinical trial is ongoing. Therefore, we carried out survey of polymorphisms of the pvs25 and pvs28 genes in P. vivax populations that are circulating in the two malaria areas of contrasting endemicity in Iran, before field application of the TBV. To characterize the polymorphisms of pvs25 and pvs28 genes, 50 isolates were analyzed by sequencing method and their gene structure was compared with parasite populations from India, Bangladesh, Indonesia, Thailand, Mexico and Brazil. Three mutations were detected in pvs25 and pvs28 including Q87K, E97Q, I130T and M52L, T65K, T140S with two and four distinct haplotypes, in comparison with the Sal I sequence type, respectively. Both haplotypes of Pvs25 were found among northern and southern P. vivax isolates; however, only two and three of the Pvs28 variants were observed among the northern and southern isolates, respectively. In conclusion, the present results show the limited sequence polymorphism of the pvs25 and pvs28 genes among field P. vivax population in Iran. These results highly encourage with respect to applicability of Pvs25 and Pvs28-based vaccine against P. vivax infection in the region, where these parasites are prevalent, whether these occur in the temperate or tropical zones. 相似文献
