RESUMO
BACKGROUND: Pneumococcal vaccination is a preventive method to reduce pneumonia related mortality. However, real-world data on efficacy of the pneumococcal vaccine in reducing mortality is lacking, especially in elderly patients. This study was conducted to assess the effects of prior pneumococcal vaccination in elderly pneumonia patients. METHODS: The data was procured from the Health Insurance Review and Assessment and Quality Assessment database. Hospitalized patients who met the criteria of community-acquired pneumonia (CAP) were included and they were grouped according to vaccination state. Patients were aged ≥ 65 years and treated with beta-lactam, quinolone, or macrolide. Patients were excluded when treatment outcomes were unknown. RESULTS: A total of 4515 patients were evaluated, and 1609 (35.6%) of them were vaccinated prior to hospitalization. Mean age was 77.0 [71.0;82.0], 54.2% of them were male, and mean Charlson comorbidity index (CCI) was 3.0. The patients in the vaccinated group were younger than those in the unvaccinated group (76.0 vs. 78.0 years; P < 0.001), and showed higher in-hospital improvement (97.6 vs. 95.0%; P < 0.001) and lower 30-day mortality (2.6 vs. 5.3%; P < 0.001). After adjusting confounding factors such as age, gender, CURB score and CCI score, the vaccinated group demonstrated a significant reduction in 30-day mortality (hazard ratio [HR] 0.58, 95% confidence interval [CI] 0.41-0.81; P < 0.01) and in-hospital mortality (HR 0.53, 95% CI0.37-0.78; P < 0.001) compared to the unvaccinated group in multivariate analysis. Vaccinated group showed better 30-day survival than those in non-vaccinated group (log-rank test < 0.05). CONCLUSIONS: Among elderly hospitalized CAP patients, prior pneumococcal vaccination was associated with improved in-hospital mortality and 30-day mortality.

PURPOSE: For successful delivery of a solid vaccine formulation into the skin using microneedles, the solubility of an adjuvant should be considered because the decrease in the dissolution rate by the addition of adjuvant decreases the delivery efficiency of the vaccine. METHODS: In this study, cholera toxin A subunit 1 (CTA1) was examined as an adjuvant to Hepatitis B vaccine (HBV) microneedles because of its good water solubility, improved safety, and positive effect as shown in intramuscular administration of a liquid vaccine. RESULTS: All solid formulations with CTA 1 dissolved in in vivo mouse skin within 30 min, and they were successfully delivered into the skin. In experiments with mice, the addition of CTA1 led to improved IgG immune response compared to the use of an aluminum hydroxide-based formulation and intramuscular administration of HBV. In addition, CTA1 induced CD8 + T cell response as much as in which the aluminum hydroxide-based formulation induced. CONCLUSIONS: CTA1 is an adjuvant that satisfies both the delivery efficiency and the immunological characteristics required for vaccine microneedles. CTA1 will be used as a potential adjuvant through vaccine microneedles.

KEY MESSAGE: This study presents an improved genome of Raphanus sativus cv. WK10039 uncovering centromeres and differentially methylated regions of radish chromosomes. Comprehensive genome comparison of radish and diploid Brassica species of U's triangle reveals that R. sativus arose from the Brassica B genome lineage and is a sibling species of B. nigra. Radish (Raphanus sativus L.) is a key root vegetable crop closely related to the Brassica crop species of the family Brassicaceae. We reported a draft genome of R. sativus cv. WK10039 (Rs1.0), which had 54.6 Mb gaps. To study the radish genome and explore previously unknown regions, we generated an improved genome assembly (Rs2.0) by long-read sequencing and high-resolution genome-wide mapping of chromatin interactions. Rs2.0 was 434.9 Mb in size with 0.27 Mb gaps, and the N50 scaffold length was 37.3 Mb (40-fold larger assembly compared to Rs1.0). Approximately 38% of Rs2.0 was comprised of repetitive sequences, and 52,768 protein-coding genes and 4845 non-protein-coding genes were predicted and annotated. The improved contiguity and coverage of Rs2.0, along with the detection of highly methylated regions, enabled localization of centromeres where R. sativus-specific centromere-associated repeats, full-length OTA and CRM LTR-Gypsy retrotransposons, hAT-Ac, CMC-EnSpm and Helitron DNA transposons, and sequences highly homologous to B. nigra centromere-specific CENH3-associated CL sequences were enriched. Whole-genome bisulfite sequencing combined with mRNA sequencing identified differential epigenetic marks in the radish genome related to tissue development. Synteny comparison and genomic distance analysis of radish and three diploid Brassica species of U's triangle suggested that the radish genome arose from the Brassica B genome lineage through unique rearrangement of the triplicated ancestral Brassica genome after splitting of the Brassica A/C and B genomes.

INTRODUCTION: The Mindray CAL 8000 is a cellular analysis line that consists of the BC-6800, an automated hematology analyzer, and the SC-120, an automated slidemaker/stainer. We evaluated the performances of the BC-6800 and the SC-120. METHODS: Four hundred and eight normal and abnormal samples were analyzed. The performance of the BC-6800 and Sysmex XE-2100 were compared, and blood films by the SC-120 and manual method were compared according to the CLSI guideline H26-A2 and H20-A2. RESULTS: Most parameters measured by the BC-6800 matched well with the XE-2100 and manual differential. The flag efficiency of the BC-6800 for blasts (95.3%) and atypical lymphocytes (92.6%) were higher while immature granulocytes (89.7%) and NRBCs (94.1%) were lower than that of the XE-2100. Additionally, the BC-6800 detected four of five samples infected with plasmodium parasites. The SC-120 showed no carry-over and expected repeatability. There was good agreement on the five-part differential including abnormal cells between blood films by the SC-120 and manually prepared blood films. The shape of the RBC was also comparable between blood films. CONCLUSION: The CAL-8000 analysis line is beneficial for precise, fast hematology work, and even more useful in malaria endemic areas.

PURPOSE: Sarcopenia is suggested to be associated with cancer-related inflammation. We assessed the clinical outcome of small cell lung cancer (SCLC) patients according to sarcopenia and the neutrophil-to-lymphocyte ratio (NLR). METHODS: A total of 117 male SCLC patients treated with first-line chemo- or chemoradiotherapy were assessed based on a retrospective chart review. The mass of the pectoralis muscle was measured by computed tomography and normalized to height. Patients with the lowest quartile of muscle mass were considered to have sarcopenia. Patients were classified into four groups according to their sarcopenia and NLR statuses: sarcopenia/high NLR, sarcopenia/low NLR, non-sarcopenia/high NLR, and non-sarcopenia/low NLR. RESULTS: Sarcopenic patients had lower progression-free survival (PFS) than did non-sarcopenic patients (median 6.0 vs. 7.5 months, p = 0.009), but the difference in overall survival (OS) was not statistically significant (median 10.5 vs. 13.5 months, p = 0.052). However, the OS of sarcopenic patients with high NLR was significantly lower than that in all other groups (median 3.2 vs. 16.0 vs. 12.5 vs. 13.7 months, respectively, p < 0.001), as was PFS (median 3.2 vs. 7.7 vs. 7.6 vs. 7.1 months, respectively, p < 0.001). On multivariate analysis, sarcopenia with high NLR was an independent prognostic factor for shorter PFS and OS. Early discontinuation of treatment (20.0 vs. 10.3 %) and treatment-related mortality (50.0 vs. 8.4 %) occurred more frequently in these patients than in the other groups (p < 0.001). CONCLUSIONS: In SCLC, sarcopenic male patients with high NLR have a poor prognosis and do not tolerate standard treatment. Intensive supportive care is needed in these patients.

BACKGROUND: The efficacy and/or tolerability of pazopanib in patients with metastatic renal cell carcinoma (mRCC) have been found to differ in Western and Asian populations. This retrospective multicenter study analyzed the results of first-line pazopanib treatment in 93 consecutive patients with mRCC who were treated at the medical oncology departments of three tertiary cancer centers in Seoul, Korea. METHODS: The decision to administer pazopanib as first-line therapy was at the discretion of the treating physician in all patients with mRCC. Patients enrolled in clinical trials were excluded to ensure that the results would reflect real-world outcomes representative of daily clinical settings. All patients received 800 mg/day pazopanib. Outcomes included response rate, progression-free survival (PFS), overall survival (OS), and safety. RESULTS: The 93 patients included72 (77 %) male and 21 (23 %) female individuals, of median age 65 years (range, 19-84 years). The median number of metastatic sites per patient was two (range, 1-5), with the lungs being the most frequently involved site. Most patients had favorable (n = 46) or intermediate (n = 36) risk as determined by Memorial Sloan Kettering Cancer Center criteria. Pazopanib was generally welltolerated: the major hematologic adverse effect was grade 1/2 anemia (14 %); and the most frequently observed non-hematologic toxicity was grade 1/2 mucositis (22 %), followed by hair discoloration and hypertension. Of the 93 patients, three (3 %) showed complete response, 52 (56 %) showed partial response, and 21 (23 %) showed stable disease, making the objective response rate 59 % and the disease control rate 82 %. At a median follow-up of 21 months, the estimated median PFS and OS were 12.2 months (95 % confidence interval, 7.1-17.4 months) and 21.9 months (95 % confidence interval, 12.9-30.9 months), respectively. CONCLUSIONS: In this retrospective study, first-line therapy with pazopanib demonstrated clinically relevant efficacy and tolerability in unselected real-world Korean patients with mRCC. OS and PFS of these Korean patients were similar to those reported in phase III trials.

BACKGROUND: Nutritional support is critical for preterm infants in the neonatal intensive care unit (NICU). A multidisciplinary nutritional support team (NST) that focuses on providing optimal and individualized nutrition care could be helpful. We conducted a thorough evaluation of clinical and nutritional outcomes in a tertiary NICU following the implementation of an NST. METHODS: This study used a retrospective approach with historical comparisons. Preterm neonates < 30 weeks gestational age or weighing < 1250 g were enrolled. Clinical and nutritional outcomes were compared before and after the establishment of the NST. Medical records were reviewed, and clinical and nutritional outcomes were compared between the two groups. RESULTS: In total, 107 patients from the pre-NST period and 122 patients from the post-NST period were included. The cumulative energy delivery during the first week of life improved during the post-NST period (350.17 vs. 408.62 kcal/kg, p < 0.001). The cumulative protein and lipid deliveries also significantly increased. The time required to reach full enteric feedings decreased during the post-NST period (6.4 ± 5.8 vs. 4.7 ± 5.1 days, p = 0.016). Changes of Z-score in weight from admission to discharge exhibited more favorable results in the post-NST period (-1.13 ± 0.99 vs.-0.91 ± 0.74, p = 0.055), and the length of ICU stay significantly decreased in the post-NST period (81.7 ± 36.6 vs. 72.2 ± 32.9 days, p = 0.040). CONCLUSIONS: NST intervention in the NICU resulted in significant improvements in the provision of nutrition to preterm infants in the first week of life. There were also favorable clinical outcomes, such as increased weight gain and reduced length of ICU stay. Evaluable data remain sparse in the NICU setting with premature neonatal populations; therefore, the successful outcomes identified in this study may provide support for NST practices.

BACKGROUND: Although chemotherapy is widely recommended for patients with metastatic biliary tract cancer, the natural course of these patients, especially those with good performance status who are indicated for chemotherapy, is not known. METHODS: We retrospectively reviewed patients with metastatic or locally advanced biliary cancer who were diagnosed at six cancer centers. Patients were eligible if they had good performance (ECOG 0-2) and no history of any treatment for cancer. The primary objective was to evaluate the survival time of patients with advanced biliary cancer with good performance who were untreated. RESULTS: Of the 1677 patients, 204 met the inclusion criteria. The median age and overall survival were 72.0 years and 7.1 months. Overall survival (months) by location was 4.7 for intrahepatic, 9.7 for extrahepatic, 4.4 for gallbladder and 11.2 for ampulla of vater cancer. In subgroup analysis, overall survival of locally advanced biliary cancer was 13.8 months and that of patients with normal carcinoembryonic antigen/carbohydrate antigen 19-9 was 10.6 months. In multivariate analysis, variables that were associated with poor prognosis were metastatic biliary cancer [hazard ratio 2.19 (P = 0.001)], high baseline carcinoembryonic antigen level (defined as >4.0 ng/ml) [hazard ratio 1.51 (P = 0.024)] and high baseline carbohydrate antigen 19-9 level (defined as >100 U/ml) [hazard ratio 1.93 (P = 0.001)]. CONCLUSIONS: Advanced biliary tract cancer with good performance status showed modest survival without any treatment. Furthermore, subgroup analysis showed that patients with normal carbohydrate antigen 19-9 or carcinoembryonic antigen level or locally advanced status had favorable survival. Further studies comparing the outcome of chemotherapy with that of best supportive care in patients with unresectable biliary tract cancer are warranted.

OBJECTIVES: The aim of this study was to investigate the clinical significance of the sum of the maximum standardized uptake value (sumSUVmax) on pretreatment positron emission tomography/computed tomography ((18)F-FDG-PET/CT) in newly diagnosed small-cell lung cancer (SCLC). METHODS: We retrospectively analyzed 145 SCLC patients from March 2005 to June 2013 who underwent pretreatment (18)F-FDG-PET/CT. The sumSUVmax was assessed in all malignant lesions up to a maximum of 5 lesions and a maximum of 2 lesions per organ according to RECIST 1.1. RESULTS: A significant difference was found between the low and high sumSUVmax groups (low vs. high sumSUVmax, 91.5 vs. 77.3%; p = 0.018) in the response rate (RR) following frontline platinum-based chemotherapy. The group with low sumSUVmax showed significantly better overall survival (OS; p < 0.001) as well as better progression-free survival (PFS; p < 0.001) compared with the group with high sumSUVmax. Moreover, multivariate analysis revealed that a high sumSUVmax alone was an independent poor prognostic factor for OS (hazard ratio 2.676; 95% confidence interval, 1.674-4.277; p < 0.001). CONCLUSIONS: This study showed that the sumSUVmax adopted from RECIST 1.1 on pretreatment (18)F-FDG PET/CT was significantly correlated with response to treatment, OS, and PFS in patients with SCLC.

PURPOSE: We investigated the efficacy and toxicity of a biweekly schedule of docetaxel and cisplatin in high-risk patients with unresectable (stages IIIB-IV) non-small cell lung cancer (NSCLC). METHODS: In this study, 48 high-risk patients with previously untreated locally advanced or metastatic NSCLC were treated with combination chemotherapy consisting of docetaxel 40 mg/m(2) and cisplatin 40 mg/m(2); both drugs were given biweekly, on days 1 and 15, every 4 weeks in an outpatient setting. RESULTS: Complete response, partial response, and stable disease were observed in 1 (2.1%), 30 [62.5%, 95% confidence interval (CI) 47.9-77.1], and 4 (8.3%) patients. The median overall survival was 15.1 months (95% CI 11.7-18.5) and the median time to progression was 7.5 months (95% CI 6.4-8.6). The major toxicity was grade 3 anemia in 7 (14.6%) patients. Grade 3/4 neutropenia was observed in 5 (10.4%) patients. Among the nonhematologic toxicities, grade 3 infection and grade 3 diarrhea were observed in 5 (10.4%) and 4 (8.3%) patients, respectively. No treatment-related mortality was found. CONCLUSIONS: As a front-line chemotherapy for high-risk patients with unresectable NSCLC in an outpatient setting, the biweekly schedule of docetaxel and cisplatin showed feasible efficacy with acceptable hematologic toxicities, comparable to the results of previous studies of triweekly or weekly schedules. Additional large randomized studies are needed to optimize the schedule and dosage of combination therapy with docetaxel and cisplatin in high-risk patients with unresectable NSCLC.

There is no previous report of fatal interstitial pneumonitis related to the administration of yttirum-90 ibritumomab tiuxetan. We report first case of fatal interstitial pneumonitis in a 35-year-old female patient with relapsed diffuse large B cell lymphoma following yttrium-90 ibritumomab tiuxetan. A pathological evaluation through a surgical lung biopsy demonstrated a "interstitial pneumonitis" pattern. Although high-dose methylprednisolone was administered, she died due to acute respiratory distress syndrome, secondary to radioimmunotherapy-induced interstitial pneumonitis. In this report, we discuss the etiology, diagnosis, and management of radioimmunotherapy-induced interstitial pneumonitis.

PURPOSE: Splenic flexure colon cancer (SFCC) is a rare disease that accounts for 2%-8% of colorectal cancers, and the extent of surgery and resection is still debatable. There have also been few studies on the safety and feasibility of laparoscopic surgery for SFCC. The purpose of this study is to evaluate outcomes and prognoses of surgery for SFCC. METHODS: We included patients with stage 1 to 3 who had undergone laparoscopic surgery for distal transverse-to-sigmoid colon cancer at 2 hospitals from March 2004 to December 2016 and collected data by retrospective design. We defined SFCC as being cancer between distal transverse and proximal descending colon. The short- and long-term outcomes of the anterior resection (AR) group (those patients who had undergone laparoscopic AR for mid and distal descending to sigmoid colon cancer) and the left colon resection (LR) group (those who had undergone laparoscopic segmental left colectomy for SFCC) were compared using propensity score matching. RESULTS: The median follow-up period was 60 months. The numbers of subjects in the AR and the LR groups were 948 and 118. After 2:1 propensity score matching, 236 vs. 118 patients were selected. There was no significant difference in 5-year disease-free survival (80.7% vs. 78.6%, P = 0.607), and both the 5-year overall survival (89.2% vs. 88.2%, P = 0.563) as well as short-term outcomes showed no statistical difference in most of the variables. CONCLUSION: Laparoscopic segmental left colectomy can be one option among the standard procedures for SFCC.
RESUMO
Anatomical variation of the cystic artery (CA) is frequently observed. However, a CA originating in a segment IV hepatic artery (HA) has been rarely reported. We report double CA originating in a right segment IV HA detected during laparoscopic cholecystectomy (LC). A 67-year-old man underwent LC for symptomatic gallstones. We ligated and divided the cystic duct initially, and performed a procedure similar to the management of CA in the hepatobiliary triangle. In contrast to the other cases, the falciform ligament was attached to gallbladder. Severe arterial bleeding was observed during the dissection. We dissected the bleeding site and found another CA for ligation. A preoperative abdominal computed tomography (CT) scan confirmed a CA originating from a segment IV HA. The patient was discharged without any events the next day. In conclusion, we report a CA originating in segment IV HA. A falciform ligament attached to gallbladder suggests the unusual CA.
RESUMO
PURPOSE: Few studies have analyzed the effects of preoperative pain education on the postoperative decision to discharge. The purpose of this study was to determine the effects of pain education and management on the decision to discharge patients after single-incision laparoscopic appendectomy (SILA). METHODS: We analyzed 135 patients who had undergone SILA for acute appendicitis between March 2017 and April 2018 in a single medical center. Of these, 72 patients (53.3%) had received preoperative pain education (group 1), and 63 (46.7%) had not (group 2). We compared perioperative outcomes and complications between the groups. RESULTS: Baseline characteristics of sex, age, body mass index, American Society of Anesthesiologist score, and systemic inflammation factors (neutrophil-lymphocyte ratio, C-reactive protein level) did not differ significantly between the groups. There were no postoperative complications for patients in either group. Perioperative consequences and pathologic findings were not significantly different between the groups; however, length of hospital was significantly shorter in group 1. CONCLUSION: Preoperative pain education in relation to postoperative pain management influenced the decision to shorten the postoperative hospital length of stay after SILA.
RESUMO
Purpose: To evaluate the educational value of laparoscopic appendectomy (LA) videos on YouTube for surgical trainees. Methods: The search term "Laparoscopic appendectomy" was used on YouTube. The top 100 videos sorted by the number of views were evaluated. Each YouTube account was analyzed, and only videos uploaded by medical physicians were included in this study. Video quality was evaluated using an arbitrary appendectomy scoring system. Video characteristics and Global Operative Assessment of Laparoscopic Skills (GOALS) scores were analyzed regarding video quality and upload source. Results: The video quality of 14 (25.0%) videos was graded as good, 36 (64.3%) moderate, and 6 (10.7%) of poor quality. Video characteristic analysis showed no differences in video quality according to the upload source (p=0.573). Video quality and upload source were not related to video length, total views, days online, number of likes, number of dislikes, number of comments, or GOALS score. Among the factors analyzed, only appendicitis severity was found to be associated with video grade (p=0.049). Conclusion: The quality of LA YouTube videos varied. Categories considered as viewer feedback were not associated with video grade or upload source. Responsible video uploading by academic institutions, and appropriate censorship by YouTube seems necessary. Further research with objective data on actual application to surgical trainees is necessary.
RESUMO
BACKGROUND/AIMS: We investigated the efficacy and toxicity of a weekly schedule of docetaxel and cisplatin as a first-line treatment in patients with recurrent or metastatic head and neck squamous cell carcinoma (R/M HNSCC). METHODS: In this study, 18 patients with previously diagnosed R/M HNSCC were treated with combination chemotherapy of weekly docetaxel 35 mg/m2 (day 1 and 8) and cisplatin 70 mg/m2 (day 1) as first-line chemotherapy, repeated every 3 weeks. RESULTS: Partial response and stable disease were observed in six patients (33.3%; 95% confidence interval [CI], 11.1% to 55.6%) and six patients (33.3%; 95% CI, 11.1% to 55.6%), respectively. The median overall survival and progression-free survival were 11.26 months (95% CI, 8.87 to 15.83) and 5.68 months (95% CI, 4.80 to 6.51), respectively. The major toxicity was grade 1/2 anemia (50%). Grade 3/4 neutropenia was observed in one patient (5.6%). Among the non-hematologic toxicities, grade 1/2 hepatotoxicity was most common (22.2%), and grade 3/4 infection was observed in one patient (5.6%). There was no treatment-related mortality. CONCLUSION: For patients with R/M HNSCC, a cisplatin and weekly docetaxel regimen showed high efficacy with tolerable toxicity as a first-line treatment.

The Glasgow Prognostic Score (GPS) serves a prognostic role in several lymphomas. The objectives of the present study were to determine whether GPS predicts clinical outcomes and to compare the utility of four prognostic scores, including GPS, in patients diagnosed with peripheral T-cell lymphoma (PTCL). We selected for this retrospective study 96 patients consecutively diagnosed with PTCL according to the World Health Organization classification from January 2002 to February 2013 and followed up in five different institutions. Low GPS was a good prognostic biomarker of progression-free survival (PFS, P = 0.030) and overall survival (OS, P = 0.013). Estimated 3-year OS rates (low-risk vs. intermediate- or high-risk) by the International Prognostic Index (IPI), the Prognostic Index for T-cell lymphoma (PIT), the International Peripheral T-cell Lymphoma Project (IPTCLP) score, and GPS were 83% vs. 44% (P < 0.001), 68% vs. 37% (P = 0.004), 71% vs. 26% (P < 0.001) and 68% vs. 51% (P = 0.031), respectively. These results indicate that GPS has prognostic value for PTCL. In addition, all four prognostic scores demonstrate their usefulness in assessing PTCL outcomes.

BACKGROUND/AIMS: Because of rarity, role of chemotherapy of bladder adenocarcinoma are still unidentified. Therefore, we performed a retrospective analysis of the clinical features and chemotherapy outcomes of bladder adenocarcinoma. METHODS: Eligible patients for this retrospective analysis were initially diagnosed with bladder adenocarcinoma and presented with a clinically no other primary site of origin. The collected data included age, gender, performance status, stage, hemoglobin, albumin, initial date of diagnosis, treatment modality utilized, response to treatment, presence of relapse, last status of patient, and last date of follow-up. RESULTS: We retrospectively reviewed 29 patients, who were treated with chemotherapy for bladder adenocarcinoma at 10 Korean medical institutions from 2004 to 2014. The median age of patients was 58 years (range, 17 to 78) and 51.7% of the patients were female. Urachal adenocarcinoma was identified in 15 patients. Of 27 symptomatic patients, 22 experienced gross hematuria. Twelve patients were treated with 5-f luorouracil based chemotherapy, five were gemcitabine based, three were taxane and others. Thirteen of them achieved complete response (10.3%) or partial response (34.5%). Median progression-free survival (PFS) and overall survival (OS) for all patients were 10.6 months (95% confidence interval [CI], 9.5 to 11.6) and 24.5 months (95% CI, 1.2 to 47.8), respectively. The cases of urachal adenocarcinoma exhibited worse tendency in PFS and OS (p = 0.024 and p = 0.046, respectively). CONCLUSIONS: Even though bladder adenocarcinoma had been observed moderate effectiveness to chemotherapy, bladder adenocarcinoma is a highly aggressive form of bladder cancer. PFS and OS were short especially in urachal carcinoma.

BACKGROUND: Amino-terminal pro-B type natriuretic peptide (NT-proBNP) is a well-established prognostic factor in heart failure (HF). However, numerous causes may lead to elevations in NT-proBNP, and thus, an increased NT-proBNP level alone is not sufficient to predict outcome. The aim of this study was to evaluate the utility of two acute response markers, high sensitivity C-reactive protein (hsCRP) and heart-type fatty acid binding protein (H-FABP), in patients with an increased NT-proBNP level. METHODS: The 278 patients were classified into three groups by etiology: 1) acute coronary syndrome (ACS) (n=62), 2) non-ACS cardiac disease (n=156), and 3) infectious disease (n=60). Survival was determined on day 1, 7, 14, 21, 28, 60, 90, 120, and 150 after enrollment. RESULTS: H-FABP (P<0.001), NT-proBNP (P=0.006), hsCRP (P<0.001) levels, and survival (P<0.001) were significantly different in the three disease groups. Patients were divided into three classes by using receiver operating characteristic curves for NT-proBNP, H-FABP, and hsCRP. Patients with elevated NT-proBNP (≥3,856 pg/mL) and H-FABP (≥8.8 ng/mL) levels were associated with higher hazard ratio for mortality (5.15 in NT-proBNP and 3.25 in H-FABP). Area under the receiver operating characteristic curve analysis showed H-FABP was a better predictor of 60-day mortality than NT-proBNP. CONCLUSIONS: The combined measurement of H-FABP with NT-proBNP provides a highly reliable means of short-term mortality prediction for patients hospitalized for ACS, non-ACS cardiac disease, or infectious disease.

2-[Tris(oleoyloxymethyl)methylamino]-1-ethane sulfonic acid (TES trioleate) is an inhibitor of phospholipase A2 (PLA2), which hydrolyzes cell membrane phospholipids to produce arachidonic acid (AA) and lysophospholipids (LysoPLs). Here, we investigated the protective effects of TES trioleate on cell damage caused by ultraviolet A (UVA) light and reactive oxygen species (ROS). Pre-incubation with 250-1000µM TES trioleate resulted in concentration-dependent protection from UVA-induced damage in HaCaT cells. Additionally, 25-1000µM TES trioleate provided protection against H2O2 in a concentration-dependent manner. In human erythrocytes treated with 1O2, 10-100µM TES trioleate showed concentration-dependent protective effects, similar to but stronger than the controls, 4-BPB and lipophilic antioxidant (+)-α-tocopherol at 100µM. TES trioleate did not have detectable radical scavenging activity. Moreover, compared with (+)-α-tocopherol and rutin, TES trioleate showed low ROS scavenging activity. Thus, although TES trioleate showed cell protective effects against UVA, H2O2, and 1O2-induced damages, these effects were not caused by the scavenging ability of the radical or ROS. Finally, pretreatment of HaCaT cells and human erythrocytes with l-α-lysophosphatidylcholine produced by PLA2 promoted increased cell damage at low concentrations. Thus, the protective effects of TES trioleate on cellular damage by UVA and ROS may be associated with inhibition of PLA2-dependent cell damage rather than ROS scavenging.
