We conducted a systematic review to summarize providers' attitudes toward pay-for-performance (P4P), focusing on their general attitudes, the effects of P4P, their favorable design and implementation methods, and concerns. An electronic search was performed in PubMed and Scopus using selected keywords including P4P. Two reviewers screened target articles using titles and abstract review and then read the full version of the screened articles for the final selections. In addition, one reference of screened articles and one unpublished report were also included. Therefore, 14 articles were included in this study. Healthcare providers' attitudes on P4P were summarized in two ways. First, we gathered their general attitudes and opinions regarding the effects of P4P. Second, we rearranged their opinions regarding desirable P4P design and implementation methods, as well as their concerns. This study showed the possibility that some healthcare providers still have a low level of awareness about P4P and might prefer voluntary participation in P4P. In addition, they felt that adequate quality indicators and additional support for implementation of P4P would be needed. Most healthcare providers also had serious concerns that P4P would induce unintended consequences. In order to conduct successful implementation of P4P, purchaser should make more efforts such as increasing providers' level of awareness about P4P, providing technical and educational support, reducing their burden, developing a cooperative relationship with providers, developing more accurate quality measures, and minimizing the unintended consequences.

The purpose of this study was to investigate the awareness of long-term care hospitals on pay for performance(P4P) program in Korea. We conducted a cross-sectional, self-administered, the internet based survey from September to October in 2010. The questionnaire was consisted of the levels of awareness and agreement about the program, their preferred design and its possible effects and unintended consequences etc. Among 837 eligible long-term care hospitals in Korea, 114 hospitals(13.6%) were participated in the survey. About one-thirds of long-term care hospitals were not aware of P4P, namely it is important to heighten an awareness of P4P. There were pros and cons on introduction of P4P in Korea. The two major reasons of objections of P4P were the concerns of unintended consequences and the possibility of strengthening government control by implementing P4P. In conclusion, to successfully implement P4P to long-term care hospitals, the Health Insurance Review & Assessment Service(HIRA) in Korea should obtain the long-term care hospitals'opinion as to implementation of P4P.

A 27-year-old pregnant woman who had one son with mental and growh retardation and dysmorphic features, was referred for genetic counselling. Cytogenetic investigations revealed 4/22 translocation in the mother(46, XX, t(4;22)(p14;P11)), partial trisomy 4p in son(46, XY, -22, +der(22), t(4;22)(p14;p11)mat). The father had normal karyotype. Amniocentesis and chorionic villi sampling were performed in 3 successive pregnancies. The karyotypes of fetus in 3rd, 4th pregnancies by amniocentesis were 46, XX, t(4;22)(p14;p11) and 46, XX, t(4;22) (p14;p11), and the karyotype of fetus in 5th pregnancy by chorionic villi sampling was found to be 46, XX, -22, +der(22) t(4;22)(p14;p11)mat. We report 3 succesive prenatally diagnosed familial partial trisomy 4p and 4/22 translocation of maternal origin with review of literature.

Promoter hypermethylation of the $p16^{INK4a}$ gene was investigated in 52 sets of samples of tumor tissue and adjacent normal tissue from Korean patients with colorectal cancer, using the proposed modified the Real-time PCR/SYBR Green detection method presented in this study. In normal tissue, 29 of 52 patients (56%) were methylated and in tumor tissue, 23 of 52 patients (44%) were methylated. The 34 cases (65.4%) showed a concordant DNA methylation pattern in both normal tissue and tumor tissue. Analyzing the association between the clinicopathologic features and DNA methylation status of the $p16^{INK4a}$ gene, the DNA methylation status according to by Duke's stage was different while other clinicopathological characteristics, including the age, sex, tumor stage, and histologic type of the patient were not found to be correlated with $p16^{INK4a}$ methylation. With multivariate logistic regression, it was observed that the DNA methylation status of $p16^{INK4a}$ gene in normal tissue was correlated with the DNA methylation status of the $p16^{INK4a}$ gene in tumor tissue (P=0.026). According to a Kaplan-Meier survival analysis, a difference in the survival rate by DNA methylation status was found, but it was not significant.

Objectives : This study was performed to investigate the metabolic site of some medicinal herbs in the liver associated with CYP (Cytochrome P450). Methods : Cytochrome P450 is the major enzymes involved in drug metabolism and bioactivation. CYP3A4 and CYP2D6, the major CYP isoforms in humans, catalyse the major proportion of drugs available on the market. Scintillation proximity assay (SPA) is often used in studies to identify compounds that inhibit CYP3A4 and CYP2D6. 28 herbal extracts and radioisotopes were attached competitively to SPA beads, and followed by measuring the remaining radioisotopes in the medium. Erythromycin and dexamethasone, inhibitors of CYP3A4 and CYP2D6, were used as controls respectively. Results : Most of the 28 herbal extracts showed dose-dependent affinity to the CYP3A4 while some of the herbs showed affinity to the CYP2D6. Conclusions : These results suggest that most of the 28 herbal extracts are metabolized safely in the liver, combined with CYP3A4 and CYP2D6.

To examine the difference of health-related quality of life (QoL) of obese patients between before and after treatment of Korean traditional medicine. This study was assessed in 18 obese-women (age 29.72${\pm}$7.38) treated by acupuncture and herbal medicine using SF-36 quality of life questionnaire between January and July 2006, a 36 item instrument yielding 8 dimensions (Social functioning, Role limitation-Physical, Role limitation-Emotion, Mental health, Vitality, Bodily pain, and General health) and a total score. Their weight was measured by Inbody 3.0 (Biospace co. Korea). QoL and body composition was assessed twice at baseline (B) and 4 weeks after treatment. Auricular acupuncture and electrical needle stimulation to abdomen, thigh, and arm fat was used twice a week and complex herb formula was prescribed according to their constitution and symptoms for 4 weeks. Herb medication was taken 2 times a day. Respective variables were analyzed with Wilcoxon signed ranks test and the level set for statistical significance was p <0.05. The mean of the body weight (P=0.000;B64,68${\pm}$6.86, 4 WKs 60.47${\pm}$5.69), fat percentage (P=0.000;B33.14${\pm}$4.86, 4 WKs 30.16${\pm}$5.34), body mass index (P=0.000;B25.18${\pm}$2.44, 4 WKs 23.46${\pm}$2.09) and fat weight (P=0.000;B21.66${\pm}$5.06, 4 WKs 18.41${\pm}$4.57) of some obese patients decreased significantly between before and after treatment for 4 weeks. Physical functioning (P=0.48;B27.06${\pm}$3.17, 4 WKs 28.00${\pm}$1.71), Mental health (P=0.01 ;B18.83${\pm}$5.25, 4 WKs 22.00${\pm}$3.73), Vitality (P=0.028;B13.89${\pm}$3.03, 4 WKs 15.44${\pm}$2.53), Bodily pain (P=.0014;B8.84${\pm}$1.75, 4 WKs 10.15${\pm}$1.78), and the total scores (P=0.001;B104.99${\pm}$12.60, 4 WKs 114.58${\pm}$11.11) of SF-36 were increased significantly after treatments. These data show some differences in QoL and BMI between before and after treatment on obesity and suggest that the treatment with acupuncture and herbal medicine have a positive impact on several domains of QoL of some obese patients. Further randomized clinical trials (RCTs) including follow-up are needed to examine whether acupuncture and herb medicine have a positive effect on QoL of treatment group compared with control group.

The present study compared leptin, adiponectin, and thyroid hormone concentrations in normal and obese dogs, and evaluated the association between leptin and adiponectin concentrations and thyroid function. The serum leptin, adiponectin, thyroid-stimulating hormone (TSH), total thyroxine (tT4), free thyroxine (fT4), triiodothyronine (T3), and cortisol concentrations were measured in 18 normal dogs (body condition score [BCS]: 4-5/9) and 16 obese dogs (BCS: 8-9/9). Leptin and T3 concentrations were higher in the obese group than the normal weight group (p < 0.01 and p < 0.05, respectively). In both groups, the T3 and leptin concentrations were correlated (r = 0.370, p < 0.05), as were the TSH and fT4 and adiponectin concentrations (r = -0.373, p < 0.05 and r = 0.369, p < 0.05, respectively). In the normal weight group, the TSH and fT4 concentrations were correlated with the adiponectin concentrations (r = -0.528, p < 0.05 and r = 0.482, p < 0.05, respectively). The results of the present study suggest that leptin and T3 concentrations are significantly higher in obese dogs than normal weight dogs, and the serum T3 and leptin concentrations are positively correlated.

Background: The Automated Fluorescent Immunoassay System (AFIAS) rotavirus assay (Boditech Med Inc., Chuncheon, Korea) is a new rapid antigen test for rotavirus detection. We evaluated the performance of this assay for detecting rotaviruses and their specific genotypes in clinical stool samples. Methods: AFIAS rotavirus assay was performed in 103 rotavirus-positive and 103 rotavirus-negative stool samples (confirmed by both PCR and ELISA), and its results were compared with those of PCR, ELISA, and immunochromatographic assay (ICA). We evaluated diagnostic sensitivity/specificity, the detectability of rotavirus subtypes, lower limit of detection (LLOD), reproducibility, cross-reactivity, and interference of AFIAS rotavirus assay. Results: Based on PCR and ELISA results, diagnostic sensitivity and specificity of the AFIAS rotavirus assay were both 99.0%. LLOD results showed that the AFIAS assay had sensitivity similar to or greater than ICA and ELISA. High reproducibility was confirmed, and no cross-reactivity or interference was detected. This assay could detect genotypes G1P[8], G2P[4], G3P[8], G4P[6], G4P[8], G8P[4], G8P[8], G9P[4], and G9P[8]. Conclusions: The AFIAS rotavirus assay showed high reproducibility, sensitivity, and specificity as well as excellent agreement with ELISA, PCR, and ICA. It detected the most common as well as unusual genotypes of rotavirus prevalent in Korea. It could be a useful onsite assay for rapid, convenient, and cost-effective detection of rotavirus infection.

Background: To compare the quality of life (QoL), the convenience of chemotherapy and satisfaction between colon cancer patients treated with FOLFOX4 and XELOX. Methods: The study was conducted in 26 patients with stage III colon cancer. Patients were received FOLFOX4 (n=17) or XELOX (n=9). QoL, convenience, and satisfaction were assessed using the Quality of Life Questionnaire-C30 (QLQ-C30), Quality of Life Questionnaire-Chemotherapy Induced Peripheral neuropathy (QLQ-CIPN) and Functional Assessment of Chronic Illness Therapy Chemotherapy Convenience and Satisfaction Questionnaire (FACIT-CCSQ), respectively. Patients completed questionnaires at baseline, at cycle 4 (C4) and cycle 8 (C8) (FOLFOX4) or at cycle 3 (C3) and cycle 6 (C6) visits (XELOX) and at their final visit. Results: In the QLQ-C30, at the final visit, XELOX patients had better functional scores than FOLFOX4 patients (physical: 85.7 vs.60.4, p=0.03; role: 83.3 vs. 57.5, p=0.04) as well as better symptom scores (constipation: 9.5 vs. 40.4, p=0.01). In CIPN, at the C6/C8 visit, XELOX patients had lower motor scale scores than FOLFOX4 patients (3.8 vs. 21.6, p=0.02). Moreover, at the C6/C8 visit, XELOX was more convenient than FOLFOX4 in FACIT-CCSQ (79.7 vs. 55.5, p=0.04). Male patients were especially likely to consider XELOX to be more convenient (90.0 vs. 55.0, p=0.01) and satisfactory (55.4 vs. 26.2, p=0.03) and fewer concern (91.0 vs. 65.0, p=0.03) than FOLFOX4. XELOX patients spent fewer days on hospital visits at C3/C4, C6/C8 and final visit (2.8 vs. 4.2, p=0.01; 2.7 vs. 4.1, p=0.01; 3.0 vs. 4.5, p=0.01). Conclusion: XELOX may be a better adjuvant chemotherapy choice for patients with colon cancer than FOLFOX4 in terms of QoL, convenience, and satisfaction.
