PURPOSE: While tumor markers (carbohydrate antigen 19-9 [CA 19-9] and carcinoembryonic antigen [CEA]) can aid in the diagnosis of biliary tract cancer, their prognostic role has not been clearly elucidated. Therefore, this study was conducted to evaluate the prognostic role of tumor markers and tumor marker change in patients with advanced biliary tract cancer. MATERIALS AND METHODS: Patients with pathologically proven metastatic or relapsed biliary tract cancer who were treated in a phase II trial of first-line S-1 and cisplatin chemotherapy were enrolled. Serum tumor markers were measured at baseline and after the first cycle of chemotherapy. RESULTS: Among a total of 104 patients, 80 (77%) had elevated baseline tumor markers (69 with CA 19-9 elevation and 40 with CEA). A decline ≥ 30% of the elevated tumor marker level after the first cycle of chemotherapy conferred an improved time to progression (TTP), overall survival (OS), and better chemotherapy response. Multivariate analysis revealed tumor marker decline as an independent positive prognostic factor of TTP (adjusted hazard ratio [HR], 0.44; p=0.003) and OS (adjusted HR, 0.37; p < 0.001). Subgroup analysis revealed similar results in each group of patients with CA 19-9 elevation and CEA elevation. In addition, elevated baseline CEA was associated with poor survival in both univariate and multivariate analysis. CONCLUSION: Tumor marker decline was associated with improved survival in biliary tract cancer. Measuring tumor marker after the first cycle of chemotherapy can be used as an early assessment of treatment outcome.

BACKGROUND: From May to July 2015, the Republic of Korea experienced the largest outbreak of Middle East respiratory syndrome (MERS) outside the Arabian Peninsula. A total of 186 patients, including 36 deaths, had been diagnosed with MERS-coronavirus (MERS-CoV) infection as of September 30th, 2015. MATERIALS AND METHODS: We obtained information of patients who were confirmed to have MERS-CoV infection. MERS-CoV infection was diagnosed using real-time reverse-transcriptase polymerase chain reaction assay. RESULTS: The median age of the patients was 55 years (range, 16 to 86). A total of 55.4% of the patients had one or more coexisting medical conditions. The most common symptom was fever (95.2%). At admission, leukopenia (42.6%), thrombocytopenia (46.6%), and elevation of aspartate aminotransferase (42.7%) were observed. Pneumonia was detected in 68.3% of patients at admission and developed in 80.8% during the disease course. Antiviral agents were used for 74.7% of patients. Mechanical ventilation, extracorporeal membrane oxygenation, and convalescent serum were employed for 24.5%, 7.1%, and 3.8% of patients, respectively. Older age, presence of coexisting medical conditions including diabetes or chronic lung disease, presence of dyspnea, hypotension, and leukocytosis at admission, and the use of mechanical ventilation were revealed to be independent predictors of death. CONCLUSION: The clinical features of MERS-CoV infection in the Republic of Korea were similar to those of previous outbreaks in the Middle East. However, the overall mortality rate (20.4%) was lower than that in previous reports. Enhanced surveillance and active management of patients during the outbreak may have resulted in improved outcomes.

BACKGROUND/AIMS: While chemoradiotherapy (CRT) is considered to be a reasonable treatment for locally advanced pancreatic cancer (LAPC), there is little information about the associated risk of gastrointestinal (GI) hemorrhage. We investigated the clinical features of GI toxicity after CRT in patients with LAPC and examined the effect of GI hemorrhage on survival. METHODS: Patients enrolled in this study had received CRT for pathologically proven LAPC. Their medical records were retrospectively reviewed. RESULTS: A total of 156 patients with LAPC (median age, 65 years; range, 39 to 90 years) who received treatment between August 2005 and March 2009 were included in this study. The most common GI toxicities were ulcer formation (25.6%) and hemorrhage (25.6%), and the most common grade 3 to grade 5 GI toxicity was hemorrhage (65%). The origins of GI hemorrhage were gastric ulcer (37.5%), duodenal ulcer (37.5%), and radiation gastritis (15.0%). The independent risk factor for GI hemorrhage was tumor location in the pancreatic body. The median overall survival of the patients with a GI hemorrhage was 13.8 months (range, 2.8 to 50.8 months) and was not significantly different from that of patients without GI hemorrhage. CONCLUSIONS: GI hemorrhage was common in patients with LAPC after CRT. Although GI hemorrhage was controlled with endoscopic hemostasis, preventive measures should be investigated to reduce needless suffering.

PURPOSE: This study was conducted to evaluate the effect of a one-session spouse-support enhancement childbirth education on childbirth self-efficacy and perception of childbirth experience. METHODS: The design of this study was a nonequivalent control group pretest-posttest experiment. The participants in the study were 31 couples in the experimental group and 30 in the control group. The experimental couples were provided with one session on spouse-support enhancement childbirth education the night before delivery. Data were collected at two hours after delivery using the Childbirth Self-Efficacy Inventory (CBSEI) and perception of childbirth experience scale. Data were analyzed using PASW statistics 18 program. Frequencies, percentage, mean, chi2 test, t-test were used for data analysis. RESULTS: Childbirth self-efficacy significantly increased in the experimental group as compared to the control group, but there was no significant difference in perception of childbirth experience in the experimental group compared to the control group. CONCLUSION: The results suggest that a one-session childbirth education has beneficial effects on enhancing childbirth self-efficacy in pregnant couples. A one-session spouse-support enhancement childbirth education is recommended as an effective nursing intervention to promote couple's childbirth self-efficacy and it is also recommended that modifications of program to promote women's childbirth experience should be considered.

OBJECTIVE: To describe the frequency and reasons for rehospitalization in patients with spinal cord injury (SCI) living in the community. METHOD: A total 388 patients with SCI living in community participated in the nationwide questionnaire-based study. A self-administered questionnaire was used. RESULTS: Of the 459 patients originally enrolled, 388 completed questionnaires, yielding response rate of 84.5%. The reasons for rehospitalization were SCI related complications (71.7%), periodic health evaluation (44.7%), and other causes (28.3%). The most frequent SCI related complications for rehospitalization were urinary tract infections (45.2%), pressure sores (39.7%), fever (18.3%), pain (18.3%), and autonomic dysreflexia (7.6%). The number of rehospitalized cases due to SCI related complication including urinary tract infection was significantly higher in complete SCI. Rehospitalization due to pressures sore was more frequent in people with paraplegia, male and complete injuries. CONCLUSION: In our study, 71.7% of patients with SCI experienced rehospitalization for SCI related complication after initial hospitalization. Urinary tract infection and pressure sores were the most common SCI related complications for rehospitalization.

This study was performed to evaluate the efficacy and toxicity of low-dose paclitaxel/cisplatin chemotherapy in patients with metastatic or recurrent gastric cancer that had failed 5-fluorouracil/platinum-based chemotherapy. Thirty-two patients with documented progression on or within 6 months after discontinuing 5-fluorouracil/platinum-based chemotherapy were enrolled. As a second-line treatment, paclitaxel (145 mg/m2) and cisplatin (60 mg/m2) was administered on day 1 every 3 weeks. Among 32 patients enrolled, 8 (25%) responded partially to paclitaxel/cisplatin, 8 (25%) had stable disease, and 14 (44%) had progressive disease. Two patients (6%) were not evaluable. The median time to progression (TTP) and overall survival for all patients were 2.9 months and 9.1 months, respectively. The most common hematologic toxicity was anemia (47%). Grade 3 neutropenia developed in three patients (9%), but no other grade 3/4 hematologic toxicity occurred. The most common non-hematologic toxicities were emesis (31%) and peripheral neuropathy (38%). Three cases (9%) of grade 3/4 emesis and 2 cases (6%) of grade 3 peripheral neuropathy developed. In conclusion, low-dose paclitaxel and cisplatin chemotherapy showed moderate activity with favorable toxicity profiles. However, relatively short TTP of this regimen warrants the development of more effective paclitaxel-based regimens other than combination with cisplatin in these patients as second-line therapies.

Serial ultrasonographic examinations were performeddaily on 9 Miniature Schnauzer bitches from the 15th dayof gestation until parturition to determine the time thegestational structures were first detected. The gestationalage was timed from the day of ovulation (day 0), whichwas estimated to occur when the plasma progesteroneconcentration was >4.0ng/ml. The gestational length in 9Miniature Schnauzer bitches was found to be 63.0+/-1.7(range 61-65) days. The initial detection of the fetal andextra-fetal structures were as follows: gestational sac atday 18.0+/-0.9 (17-19); zonary placenta in the uterine wallat day 24.9+/-1.1 (23-26); yolk sac membrane at day 25.0+/-0.9 (24-26); amnionic membrane at day 27.7+/-1.0 (26-29); embryo initial detection at day 22.6+/-0.5 (22-23);heartbeat at day 23.4+/-0.5 (23-24); fetal movement at day32.5+/-0.8 (32-34); stomach at day 31.2+/-1.6 (29-33);urinary bladder at day 32.6+/-1.8 (31-35); skeleton at day34.9+/-1.6 (34-38) and kidney at day 42.2+/-0.7 (41-43).

OBJECTIVE: Although hemodialysis using heparin bound Hemophan (HBH-HD) has been reported to be a possible modality in patients at risk of bleeding, the efficiency and safety of HBH-HD is not certain. Therefore, we prospectively compared the safety and efficiency of HBH-HD with those of saline flushing HD (SF-HD) and HD using low dose heparin (LDH-HD) in 13 HD patients at risk of bleeding in a cross-over design. METHODS: The safety and efficiency were evaluated by measuring activated partial prothrombin time (aPTT) before and during HD, hemostasis time after needle removal, total blood compartment volume (TBCV) loss of dialyzer, urea clearance (K) and Kt/V. RESULTS: There was no difference in compression time needed to achieve hemostasis at puncture site after needle removal between HBH-HD, SF-HD and LDH-HD. During HBH-HD, there was a slight increase in aPTT at 15 min (50.6+/-4.5 sec), compared to predialysis levels (40.9+/-4.7 sec). In this cross- over study, aPTT during dialysis session was markedly higher in LDH-HD than those in HBH-HD or SF-HD (p<0.05). The loss of TBCV of the dialyzer was greater in SF-HD than HBH-HD or LDH-HD (17.4+/-1.9% vs. 12.4+/-1.4% vs. 10.1+/-1.8%). However, there was no difference in K (212.0+/-30.7 vs. 217.2+/-36.9 vs. 221.6+/- 29.5 mL/min) and Kt/V (1.22+/-0.12 vs. 1.24+/-0.16 vs. 1.26+/-0.18). CONCLUSION: We concluded that the safety and efficiency of HBH-HD are not different compared to SF-HD or LDH-HD and HBH-HD could an alternative hemodialysis method in patients at risk of bleeding.

To evaluate the toxicity and efficacy of a reduced dose intensity (mini-) FOLFOX-4 regimen as a first-line palliative chemotherapy in elderly patients (> or =70 yr of age) with advanced colorectal cancer, data from prospective databases at Seoul National University Bundang Hospital and Seoul Municipal Boramae Hospital were analyzed. A total of 20 patients were enrolled between January 2001 and August 2004, and were treated with oxaliplatin 65 mg/m2 on day 1, and with 2-hr infusions of leucovorin 150 mg/m2 followed by a 5-FU bolus (300 mg/m2) and 22-hr continuous infusions (450 mg/m2) for 2 consecutive days every 2 weeks until progression, unacceptable toxicity or patient refusal. Sixteen patients were evaluable for response with an overall response rate of 43.8%. Median progression-free survival was 4.8 months (95% CI: 3.0-6.7) and overall survival was 13.5 months (95% CI: 11.1-16.0). The main side effects were anemia and neutropenia, which were observed in 20.8% and 17.7%, respectively, of the total cycles administered. There were no grade 4 toxicities and only one patient suffered from febrile neutropenia. No grade 3 toxicities occurred except for anemia (5.2%) and vomiting (1.0%). In conclusion, the mini-FOLFOX-4 regimen was found to be well tolerated with acceptable toxicity, and to provide a benefit for elderly patients with colorectal cancer.
