Abstract
PURPOSE/OBJECTIVE(S) The local ablative therapy for oligometastatic disease (OMD) has the potential to delay further metastases and improve survival. However, it has not been fully elucidated how prostate primary radiotherapy (PPR) and metastasis-directed radiotherapy (MDR) affect prognosis in each different OMD scenario. Herein, we tried to provide efficacy and future perspectives for MDR in oligometastatic prostate cancer. MATERIALS/METHODS Patients diagnosed with prostate cancer between 2010 and 2019 and treated for OMD (≤5 active lesions), which occurred synchronously or metachronously, were included. All patients received MDR at all detected lesions (OMDRT). OMDRT which was performed as soon as OMD was detected was classified as early, and OMDRT for progressions after hormone therapy was classified as late. The primary endpoint was survival after OMDRT, and timing of progression after RT was also analyzed. RESULTS A total of 82 patients with oligometastatic prostate cancer received OMDRT. Among 36 patients with synchronous OMD, 58% received PPR at diagnosis, and 64% received early OMDRT. Among 46 patients with metachronous OMD, 80% received early OMDRT, and 28 received sequential OMDRT for repetitive OMD events. With a median follow-up of 32 months after OMDRT, 54 patients experienced progression and 5-year survival was 78%. Survival was highest in patients with synchronous OMD and early RT (5-year 86%), and 5-year survival of patients with metachronous OMD and early RT was significantly higher than those with late RT (78% vs. 44%, p = 0.003). Survival of patients with synchronous OMD and PPR was significantly higher than those without PPR or with metachronous OMD (5-year 90% vs. 66%, p = 0.030), by delaying progressions (17.9 vs. 7.0 months, p = 0.005). CONCLUSION Survival gain could be achieved through OMDRT in oligometastatic prostate cancer, especially in synchronous OMD status. Also, it was possible to improve the prognosis further when OMDRT was performed early and with PPR.

Abstract
PURPOSE/OBJECTIVE(S) The pattern of locoregional recurrence specifically after robotic-assisted laparoscopic prostatectomy (RALP) for prostate adenocarcinoma is still unknown. In this study, we reviewed pelvic magnetic resonance images (MRI) after postoperative biochemical recurrence (BCR) and drew a map of locoregional recurrence to support evidence of determining the optimal target volume of salvage radiotherapy in a post-RALP BCR scenario. MATERIALS/METHODS We have retrospectively searched 7,583 prostate adenocarcinoma patients who have received RALP in our institution between January 2010 and December 2021, and found a pool of highly selected patients with gross tumor recurrence confirmed by post-BCR pelvic MRIs and did not have other histories of malignancy. BCR was defined as the serum PSA more or equal to 0.2 ng/mL, or three consecutive increases. Patients with serum PSA nadir more or equal to 0.2 ng/mL on the 90th postoperative day (POD 90) were excluded to guarantee successful tumor removal. We have reviewed serum PSA levels using R codes, MRI and pathological reports using Excel, and descriptive statistics using SPSS 25. The gross lesions were contoured on the correlating MRIs using MIM Maestro 7.1. The RT structure DICOM files were merged into a map using MATLAB 2022b. In addition, we have conducted Fisher exacted test, Mann-Whitney U test, and logistic regression to identify risk factors for regional recurrence. RESULTS A total of 173 patients were identified with locoregional recurrence from post-BCR pelvic MRIs, and 139 (80.3%) patients were in the high-risk group or very-high-risk group according to the NCCN guidelines: 57 (32.9%) patients with histological grade group 5, 50 (28.9%) patients with initial PSA over 20 ng/mL, 114 (65.9%) patients with extracapsular extension, 55 (31.8%) patients with seminal vesicle invasion, and 15 (9%) patients with pN1. The median follow-up was 4.7 (IQR 2.8-6.9) years for pelvic MRIs and 5.8 (IQR 4.0-8.6) years for serum PSA. The BCF survival was median of 10.7 (IQR 4.6-19.1) months, and the locoregional recurrence-free survival was median of 24.6 (IQR 9.7-49.4) months for this subgroup of patients. At first locoregional recurrence, 148 (85.5%) patients were local only, 20 (11.6%) patients were regional only, and 5 (2.9%) patients were both local and regional. Out of the 25 patients with regional recurrence, the incidence of gross tumor recurrence differed by nodal sites: 3 (12%) in perirectal space, 5 (20%) in internal iliac, 7 (28%) in obturator, 13 (52%) in external iliac, and 6 (24%) in common iliac lymph nodes. CONCLUSION We have found 173 patients and were able to map reliable gross tumor recurrence sites after RALP and confirmed by pelvic MRIs following BCR. The map supports evidence of using the existing consensus pelvic clinical target volume of salvage radiotherapy, in a post-RALP BCR scenario.

Abstract
PURPOSE/OBJECTIVE(S) This study aimed to develop a graded prognostic assessment (GPA) model integrating genomic characteristics in patients with elderly glioblastoma (eGBM), and compare the efficacy between conventionally fractionated radiotherapy (CFRT) vs. hypofractionated radiotherapy (HFRT) in each risk group. MATERIALS/METHODS Patients aged ≥65 years who underwent surgical resection followed by radiotherapy (RT) with or without temozolomide (TMZ) for newly diagnosed IDH-wildtype eGBM between 2006 and 2021 were included in this multicenter cohort study. Patients who were planned for a ≥6-week or ≤4-week radiotherapy were regarded as being treated with CFRT or HFRT, respectively. Based on the prognostic factors significantly identified through multivariate analysis for overall survival (OS), we developed the molecular GPA for eGBM (eGBM-molGPA) and assigned 0.0, 0.5, and 1.0 points in proportion to the corresponding hazard ratio (HR) of each factor. Then, the survival outcomes by treatment groups were evaluated according to the eGBM-molGPA scores. RESULTS A total of 334 and 239 patients who underwent CFRT and HFRT were included, respectively, and 86% of patients were treated with TMZ-based chemoradiation. With a median follow-up of 17.4 months for survivors, the median OS was 18.7 months for CFRT plus TMZ group, 15.1 months for HFRT plus TMZ group, and 10.4 months for RT alone group, respectively (all p<0.001). In the multivariate analysis, Karnofsky performance scale, surgical extent, TMZ, and the methylation status of the MGMT promoter were identified as strong prognostic factors for OS, with an estimated HR of greater than 1.5 (all p<0.001). Additionally, subventricular zone involvement, temporalis muscle thickness, RT regimen, and the mutation status of TERT promoter and TP53 gene were found to be significant prognostic factors for OS, with an estimated HR of less than 1.5. The eGBM-molGPA was established based on these prognostic factors (Table 1) and patients were allocated to three risk groups, which included high risk (total score of 3.0-4.5), intermediate risk (1.5-2.5), and low risk (0.0-1.0). Patients treated with CFRT plus TMZ had significantly improved OS compared to those treated with HFRT plus TMZ or RT alone in the low and intermediate risk groups (p<0.001). However, in the high-risk group, there was no significant difference in OS between treatment options (p = 0.770). CONCLUSION CFRT plus TMZ can be a more effective strategy for selected eGBM patients compared to HFRT. For high-risk patients, a protracted treatment schedule might not be beneficial. The novel eGBM-molGPA can be used as a clinical tool for choosing wisely among treatment options. Further prospective studies are warranted to establish optimal RT guidelines for eGBM patients.

Abstract
The global prevalence of GERD is substantially increasing each year, and GERD is a chronic disease that reduces the quality of life of patients. The efficacy of conventional drugs is diverse, and most require long-term or lifetime administration; thus, the development of more effective therapeutic agents is needed. Herein, a more effective treatment for GERD was tested. We investigated whether JP-1366 affected gastric H+/K+-ATPase activity and used the Na+/K+-ATPase assay to confirm the selectivity of H+/K+-ATPase inhibition. To clarify the mechanism of enzyme inhibition, JP-1366 and TAK-438 were analyzed by Lineweaver-Burk. Also, we investigated the effects of JP-1366 in various models involving reflux esophagitis. We found that JP-1366 mediates strong, selective, and dose-dependent inhibition of H+/K+-ATPase. We found that JP-1366 significantly suppressed gastric acid secretion in histamine-treated pylorus-ligated rats in a dose-dependent manner. Additionally, we confirmed that JP-1366 inhibited histamine-stimulated gastric acid secretion in the HPD model. JP-1366 exhibited a more than 2-fold higher inhibitory effect on esophageal injury than TAK-438 in GERD lesions and had a more potent inhibitory effect in indomethacin- or aspirin-induced gastric ulcer rat models than TAK-438. Additionally, JP-1366 inhibited gastric ulcers. These results support the possibility that JP-1366 is a good candidate drug for treating acid-related diseases.

Abstract
OBJECTIVE To evaluate the clinical efficacy and safety of cefetamet pivoxil for the treatment of acute bacterial rhinosinusitis in Korean patients compared to treatment with cefdinir. METHODS A prospective, multicenter, randomized double-blind, comparative study was conducted by the Departments of Otorhinolaryngology-Head and Neck Surgery at 17 hospitals or universities in the Republic of Korea from March 2017 to April 2019. A total of 309 patients were screened and 249 patients participated in the study. RESULTS Treatment with cefetamet pivoxil for 2 weeks showed 82.4% clinical cure and improvement rates in patients with acute bacterial rhinosinusitis compared to 84.68% in those taking cefdinir for 2 weeks, showing that cefetamet pivoxil administered twice a day for 2 weeks was as effective as cefdinir 3 times a day for 2 weeks for the treatment of acute bacterial rhinosinusitis. The overall adverse reaction rates of both drugs were 10.56% in the cefetamet pivoxil group and 15.49% in the cefdinir group, without serious adverse events or drug reactions. CONCLUSIONS Cefetamet pivoxil twice a day was as efficacious and safe as cefdinir 3 times a day for the treatment of acute bacterial rhinosinusitis, which suggested that cefetamet pivoxil may be a suitable alternative to cefdinir.

Abstract
OBJECTIVE Acute low back pain (LBP) is a common condition that can be chronic if not properly treated. Aceclofenac and eperisone hydrochloride are commonly prescribed drugs for acute LBP and muscle spasms. Therefore, NVP-1203, a fixed-dose combination of 100 mg aceclofenac and 75 mg eperisone hydrochloride, is being developed. This study aimed to evaluate the efficacy and safety of NVP-1203 compared to those of a single administration of 100 mg aceclofenac in patients with acute LBP and muscle spasms. PATIENTS AND METHODS Overall, 455 patients with acute LBP and muscle spasms were enrolled. The patients were assigned to NVP-1203 or Airtal group (aceclofenac 100 mg). The primary efficacy endpoint was the mean change in the 100 mm pain movement and resting visual analog scale (VAS) scores on treatment day 7. RESULTS The mean change in the 100 mm pain movement/resting VAS scores from baseline to day 7 was -49.7 ± 21.5/-41.0 ± 19.4 mm and -38.8 ± 18.9/-33.8 ± 18.0 mm for the NVP-1203 and Airtal groups, respectively. The differences between the two groups were statistically significant (movement, p < 0.0001; resting, p = 0.0002). Differences in least-square (LS) mean change of the 100 mm pain movement/resting VAS score between the two groups using the analysis of covariance (ANCOVA) model was -10.2/-7.4 mm, and the upper limit of the 95% confidence interval was -6.44/-4.16 mm. CONCLUSIONS NVP-1203 is more effective in reducing pain than the 100 mg aceclofenac alone. However, the two drugs have similar safety profiles in patients with acute LBP and muscle spasms.

Abstract
OBJECTIVES We compared the lengths of a nasoseptal flap (NSF) and skull base according to race, age, and sex. METHODS We performed paranasal sinus computed tomography in 19,961 adult patients between 2003 and 2022. The race of the patients was East Asian (n = 71), Caucasian (n = 71), or Middle Eastern (n = 71). The expected lengths of the NSF and anterior skull base defect were measured and analyzed according to race, age, and sex. RESULTS Compared with Caucasians and Middle Easterners, East Asians had a shorter NSF length (p < 0.001) and lower ratio of the expected NSF length to the expected defect length (p < 0.001). There was no difference in the values among age groups. The expected NSF length was longer, and the ratio of the expected NSF length to the expected defect length was higher, in males than females (p < 0.001 for both). CONCLUSIONS East Asians and females had a shorter NSF length and lower ratio of expected NSF to surgical defect lengths after anterior skull base reconstruction compared with the other races and with males, respectively. Anatomical differences should be considered when long NSF lengths are required, such as for anterior skull base reconstruction.

Abstract
Abstract
Introduction
Cardiovascular disease (CVD) is the global leading cause of death, and the economic and social burden of CVD is still increasing, Smoking is one of the top three leading risk factors for the disease and one of the well-established and important modifiable risk factors for CVD. However, the time course of CVD risk after smoking cessation is unclear.
Purpose
We assess the association between smoking and CVD and the incidence of CVD with years quitting smoking.
Methods
This study used the Korean National Health Insurance Service (NHIS) database. Self-reported smoking habit data were used to classify participants as current, former or never smokers and to investigate the duration and intensity of smoking. Smoking records of participants were updated every 2 years, and all participants whose smoking records were changed or unclear were excluded. The primary outcome was the development of CVD, including myocardial infarction, stroke, heart failure, and cardiovascular death.
Results
Total 5,391,231 participants (953,756 subjects were current smokers, 104,604 subjects were former smokers, 4,432,871 subjects never smoker) were followed-up for an average of 4.2 years. The mean age was 45.8 years, 39.9% were male. Cumulative pack-year (PY) were 14 in current smoker, 10.5 in former smokers at baseline. The median years of quitting smoking for former smoker was 4.
Regardless of whether smoking continues or not, a dose-dependent relationship exists between smoking and CVD (Fig. 1). For those smoked less than 8PY, smoking cessation significantly lowered the CVD risk within 10 years compared to current smokers, and the CVD risk was not significantly different from never smokers (Fig. 2A). However, in the case of smokers over 8PY, although smoking cessation affects the reduction of CVD, the CVD risk decreases slowly over decades, and it takes more than 20 years for the effect of smoking on the CVD risk to disappear (Fig. 2B).
Conclusion
Smoking and CVD have a dose-dependent relationship, and mild smokers with less than 8PY had a similar CVD risk to never smokers when quitting smoking. However, for heavy smokers over 8PY, it takes a long time for the CVD risk from smoking to disappear

Abstract
OBJECTIVES We estimated volume changes in the posterior bony wall of the sphenoid sinus, as well as alterations in nasal function (including olfactory function and subjective symptoms), after sphenoid mucosal repositioning using the endoscopic endonasal transsphenoidal approach (EETSA). METHODS During 2010 and 2021, 13 patients underwent sphenoid mucosal repositioning during EETSA, while 24 patients (the control group) did not. Pre- and postoperative paranasal sinus computed tomography and the Mimics program were used to evaluate three-dimensional changes in the posterior wall of the sphenoid sinus. All patients underwent the Connecticut Chemosensory Clinical Research Center (CCCRC) test, the Cross-Cultural Smell Identification Test (CCSIT), Nasal Obstruction Symptoms Evaluation (NOSE), the Sino-Nasal Outcome Test-20 (SNOT-20), and visual analog scale (VAS) evaluation. RESULTS The increase in the volume of the posterior wall of the sphenoid sinus after surgery was objectively smaller in the sphenoid mucosal repositioning group than in the control group (P = .046). However, this did not affect olfactory function (as revealed by the CCCRC test or the CCSIT) or subjective symptoms (as revealed by the NOSE, SNOT-20, and VAS scores) (all P > .05). CONCLUSION Surgical closure via sphenoid mucosal repositioning during EETSA reduces the volume of the posterior wall of the sphenoid sinus and facilitates re-operation. We suggest that sphenoid mucosal repositioning is appropriate during EETSA. LEVEL OF EVIDENCE 4 Laryngoscope, 2022.

Abstract
Importance Adjuvant chemotherapy in patients with stage III colon cancer prevents recurrence by eradicating minimal residual disease. However, which patients remain at high risk of recurrence after completing standard adjuvant treatment cannot currently be determined. Postsurgical circulating tumor DNA (ctDNA) analysis can detect minimal residual disease and is associated with recurrence in colorectal cancers. Objective To determine whether serial postsurgical and postchemotherapy ctDNA analysis could provide a real-time indication of adjuvant therapy efficacy in stage III colon cancer. Design, Setting, and Participants This multicenter, Australian, population-based cohort biomarker study recruited 100 consecutive patients with newly diagnosed stage III colon cancer planned for 24 weeks of adjuvant chemotherapy from November 1, 2014, through May 31, 2017. Patients with another malignant neoplasm diagnosed within the last 3 years were excluded. Median duration of follow-up was 28.9 months (range, 11.6-46.4 months). Physicians were blinded to ctDNA results. Data were analyzed from December 10, 2018, through June 23, 2019. Exposures Serial plasma samples were collected after surgery and after chemotherapy. Somatic mutations in individual patients' tumors were identified via massively parallel sequencing of 15 genes commonly mutated in colorectal cancer. Personalized assays were designed to quantify ctDNA. Main Outcomes and Measures Detection of ctDNA and recurrence-free interval (RFI). Results After 4 exclusions, 96 eligible patients were eligible; median patient age was 64 years (range, 26-82 years); 49 (51%) were men. At least 1 somatic mutation was identified in the tumor tissue of all 96 evaluable patients. Circulating tumor DNA was detectable in 20 of 96 (21%) postsurgical samples and was associated with inferior recurrence-free survival (hazard ratio [HR], 3.8; 95% CI, 2.4-21.0; P < .001). Circulating tumor DNA was detectable in 15 of 88 (17%) postchemotherapy samples. The estimated 3-year RFI was 30% when ctDNA was detectable after chemotherapy and 77% when ctDNA was undetectable (HR, 6.8; 95% CI, 11.0-157.0; P < .001). Postsurgical ctDNA status remained independently associated with RFI after adjusting for known clinicopathologic risk factors (HR, 7.5; 95% CI, 3.5-16.1; P < .001). Conclusions and Relevance Results suggest that ctDNA analysis after surgery is a promising prognostic marker in stage III colon cancer. Postchemotherapy ctDNA analysis may define a patient subset that remains at high risk of recurrence despite completing standard adjuvant treatment. This high-risk population presents a unique opportunity to explore additional therapeutic approaches.

Abstract
OBJECTIVES Since 2007, the Korean government has provided a free health screening to the elderly starting at the age of 66 years. The purpose of this study was to evaluate the association between this general health screening and the incidences of stroke and myocardial infarction and mortality. STUDY DESIGN The study design used in this study is a retrospective cohort study. METHODS The study was conducted using the universe of insurance claims data of Korea and followed a cohort of individuals aged 66 years in 2009 from 2006 through 2016 (n = 354,194). We assessed the association between receipt of the national health screening and health outcomes using propensity matching and Cox proportional hazard models. RESULTS We found that the receipt of the national health screening was associated with a reduction in negative health outcomes. The hazard ratio for stroke was 0.89 (P < 0.001), 0.88 (P < 0.001) for myocardial infarction and 0.58 for death (P < 0.001). CONCLUSION Korea's national health screening was associated with reductions in cardiovascular morbidity and mortality in the elderly.

Abstract
IMPORTANCE The newly emerged coronavirus disease 19 (COVID-19), is threatening the world. Olfactory or gustatory dysfunction is reported as one of the symptoms worldwide. As reported so far, different clinical features have been reported according to outbreak sites and gender; most of the patients, who complained of anosmia or hyposmia, were Europeans. We had a fast review for novel articles about COVID-19 infection and olfactory function. OBSERVATIONS Rapid reviews for COVID-19 or other viral infection and olfactory and/or gustatory dysfunctions were done in this review. Up to date, a lot of reports have shown that olfactory dysfunction is related to viral infections but no exact mechanism, clinical course, and definite treatment have been discovered, which is also same in COVID-19. In general, intranasal steroid (INS) and oral steroid for short time help improve the recovery of the olfactory function in case of olfactory dysfunction after virus infection. Considering severe respiratory complications and immunocompromised state of COVID-19, the use of steroid should be limited and cautious because we do not have enough data to support the usage of steroid to treat olfactory dysfunction in the clinical course of COVID-19. CONCLUSIONS AND RELEVANCE In the days of pandemic COVID-19, we should keep in mind that olfactory dysfunctions, even without other upper respiratory infection or otolaryngologic symptoms, might be the early signs of COVID-19.

Abstract
OBJECTIVE Particulate matter (PM), which contains organic compounds and toxic metals, is the major cause of air pollution. PM enters the body, causing various health problems. Although the effects of PM on the lower respiratory tract have been extensively investigated, the effects on the upper respiratory tract (including the nasal cavity) require further evaluation. To investigate the effect of fluticasone propionate (FP) on nasal fibroblasts exposed to UPM. METHODS Samples of inferior turbinate tissue were obtained from six patients. The fibroblasts isolated from these samples were exposed to UPM and/or FP. The expression of interleukin (IL)-6, CXC chemokine ligand (CXCL) 1, IL-1β, and tumour necrosis factor-alpha (TNF-α) in nasal fibroblasts was analysed using real-time PCR and enzyme-linked immunosorbent assays. The protein levels of nuclear factor kappa B (NF-κB) and signal transducer and activator of transcription 3 (STAT3) were analysed by western blotting. RESULTS FP reversed the UPM-induced reduction in cell viability. The mRNA and protein levels of IL-6, CXCL1, IL-1β, and TNF-α were significantly increased by UPM. FP reversed the UPM-induced increases in the protein levels of NF-κB and phosphorylated-STAT3 in a dose-dependent manner. In addition, TNF-α, an inducer of NF-κB, reversed the FP-induced reduction in the levels of signalling molecules. CONCLUSION UPM induces the expression of IL-6, CXCL1, IL-1β, and TNF-α in nasal fibroblasts and this effect is reversed by FP via the STAT3 and NF-κB signalling pathways. These results suggest that FP has therapeutic potential for nasal diseases related to UPM, such as allergic and chronic rhinitis.

Abstract
BACKGROUND Particulate matter (PM) can cause various negative acute and chronic diseases of the respiratory system, including the upper airways. Curcumin has been reported to have anti-inflammatory and anti-oxidative effects; therefore, we investigated the effects of curcumin on nasal fibroblasts exposed to urban PM (UPM). METHODS Samples of inferior turbinate tissue were obtained from six patients. Flow cytometry was used to assess the levels of reactive oxygen species (ROS) following the treatment of nasal fibroblasts with UPM and/or curcumin. We evaluated the effects of UPM and/or curcumin on the expression of phosphorylated ERK, Nrf2, HO-1, and SOD2 in fibroblasts by Western blotting. RESULTS When UPM was applied to nasal fibroblasts, ROS production was significantly increased in a dose-dependent manner. UPM-exposed fibroblasts caused the activation of ERK to increase HO-1 expression and decrease SOD2 expression. Treatment with curcumin reduced the UPM-mediated increase in ROS; this decrease in ROS occurred in a dose-dependent manner. The UPM-induced activation of ERK was inhibited by curcumin. Nrf2 production was also promoted to increase the expression of HO-1 and SOD2 by curcumin. CONCLUSION Curcumin reduced ROS production caused by UPM in human nasal fibroblasts in a dose-dependent manner, suggesting that curcumin has anti-oxidative effects and may be useful in the treatment of nasal diseases caused by UPM, such as allergic and chronic rhinitis.

BACKGROUND Sarcopenia may worsen disease progression and lead to poor outcomes in chronic obstructive pulmonary disease (COPD). OBJECTIVES We aimed to determine the effect of BMI on the development of COPD and mortality. METHODS We enrolled 437 584 participants registered in the physical health check-up cohort database of the Korean National Health Interview Survey from 2002 to 2003, and we defined COPD diagnosis based on the ICD-10 code and prescribed medication. BMI (kg m-2 ) classified them to five groups (low BMI < 18.5, normal BMI 18.5-23, overweight 23-25, obesity 25-30, severe obesity ≥30) at baseline. RESULTS Participants in the low BMI group had a significantly higher rate of COPD development for 13 years (7.6%) than those in other groups (3.4-4.1%, P < 0.0001). Amongst never or light smokers, COPD development in the low BMI group (5.6-6.7%) was significantly higher than that in other groups (2.8-4.7%). Similarly, amongst participants with a smoking history of ≥30 years, COPD development in the low BMI group (20.1%) was higher than those in other groups (8.4-12.4%). On multivariable analysis, normal or higher than normal body weight was significantly protective against the development of COPD (hazard ratio [HR], 0.609-0.739,) compared to low BMI. COPD-free-survival (HR, 0.491-0.622) and overall survival (HR, 0.440-0.585) were also better in them compared to those with low BMI (all P < 0.0001). CONCLUSIONS Low BMI is an important risk factor for COPD development and mortality. Maintaining adequate body weight may reduce the risk for COPD development and mortality.

Abstract
Efficient one-pot oxidative esterification of 5-hydroxymethylfurfural (HMF) to furan-2,5-dimethylcarboxylate (FDMC) was achieved under extremely mild reaction conditions by using AuPd alloy nanoparticles (NPs) supported on Fe3 O4 . A high yield of FDMC (92 %) was obtained at room temperature under atmospheric O2 . The reaction proceeded through the synergistic effects of the AuPd heterobimetallic catalyst system. The most effective molar ratio of noble metal contents for HMF oxidation was 1.00:1.18. If Au-Fe3 O4 NPs were used as the catalyst, selective synthesis of 5-hydroxymethylfuroic acid methyl ester (HMFE) was achieved. Additionally, the AuPd-Fe3 O4 catalyst could be successfully reused.

Abstract
This experiment was conducted to study the effects of orally administered carvacrol essential oils on immune response and inflammation-related genes expression in broilers challenged by lipopolysaccharide (LPS). Eighty 28-day-old (1.28 ± 0.15 kg) ROSS 308 broilers were assigned to a 2 × 2 factorial arrangement of treatments (20 pens of 1 chick/trt). Factors were carvacrol essential oil (orally administered or non-orally administered) and LPS (challenged or non-challenged). Individually housed broilers were randomly assigned (n = 20 broilers per treatment: 10 males and 10 females) to four treatments: (1) basic diet (CTR), (2) basic diet + carvacrol (CAR), (3) basic diet + LPS-challenge (LPS), (4) basic diet + carvacrol + LPS-challenge (CAR+LPS). All were fed with the same diet. The experimental period was for 15 d, after which injecting LPS significantly up-regulated the gene expression levels of TNF-α (P < 0.05), IL-1β (P < 0.05), IL-6 (P < 0.05), IL-8 (P < 0.05), TLR2 (P < 0.05), TLR4 (P < 0.05), NF-κB p65 (P < 0.05), AVBD-9 (P < 0.05), and SIgA(P < 0.05) compared with the CTR group; the broilers were challenged by LPS after oral administration of carvacrol, they had significant lower on the gene expression levels of TNF-α (P < 0.05), IL-1β (P < 0.05), IL-6 (P < 0.05), TLR4 (P < 0.05), NF-κB p65 (P < 0.05), and AVBD-9 (P < 0.05) than the LPS group. In conclusion, the broilers orally administrated carvacrol essential oils inhibited the secretion of inflammatory cytokines caused by LPS, affected the pathway of TLRs/NF-κB, and showed an anti-inflammatory function.

Abstract
BACKGROUND Exposure to urban particulate matter (UPM) has been studied as a cause of various health problems. Although the association between UPM and the respiratory tract has been well studied, further research is required to characterize the effects of UPM on the upper respiratory tract. We investigated the effects of UPM-induced reactive oxygen species (ROS) production on cultured human nasal fibroblasts, as well as the protective effects of α-lipoic acid (ALA) on ROS production and the underlying signaling pathways involved in ROS inhibition. METHODS Human turbinate tissue specimens were collected from 6 patients. The effects of UPM on the viability of cultured nasal fibroblasts were determined. A fluorescent malondialdehyde assay was used to measure ROS levels. Real-time reverse transcription polymerase chain reaction was used to measure the messenger RNA levels of genes encoding Nrf2, the antioxidant response elements (AREs) (HO-1, NQO1), and the proinflammatory cytokines (interleukin-6 and interleukin-8) before and after ALA treatment. Western blotting analyses were used to measure nuclear and cytosolic Nrf2 and AREs. RESULTS UPM reduced cell viability and increased ROS expression in nasal fibroblasts. ALA treatment decreased ROS production in UPM-exposed fibroblasts via the Nrf2, HO-1, and NQO-1 pathways. Also, ALA treatment abrogated increases in the interleukin-6 and -8 levels induced by UPM in nasal fibroblasts. CONCLUSION UPM exposure resulted in increased ROS production in nasal fibroblasts. ALA treatment inhibited this increase via the Nrf2 pathway, suggesting that ALA may have a protective effect against rhinitis caused by ROS expression induced by exposure to UPM.

Abstract
OBJECTIVE To examine the effect of xylitol nasal irrigation in a large sample size of patients who had undergone nasal surgery. STUDY DESIGN Double-blinded randomized controlled crossover study. SETTING Tertiary referral center. METHODS The study included 100 patients with sinonasal disease who underwent endoscopic sinus surgery (ESS), septoplasty, or both concurrently. To identify patients with allergic sensitization, serum-specific immunoglobulin E levels were measured. Nasal symptoms were evaluated with the NOSE (Nasal Obstruction Symptoms Evaluation) and SNOT-20 (Sino-Nasal Outcome Test-20) and via visual analog scale (VAS) scores. RESULTS In the ESS group (n = 34), the general nasal symptom score evaluated by the SNOT-20 showed significantly greater improvement in the xylitol group versus the saline group ( P = .022). VAS symptom scores for sneezing ( P = .003), headache ( P = .02), and facial pain ( P = .037) were also more improved in the xylitol group. In the septoplasty group (n = 39), the VAS score for nasal stuffiness showed a significantly greater improvement in the xylitol group when compared with the saline irrigation group ( P = .001). Among the patients with allergic sensitization (n = 31), rhinorrhea symptoms improved significantly more in the xylitol group than in the saline group ( P = .024). The preference survey showed that more than half of the patients in each surgical group preferred xylitol irrigation. CONCLUSION We found that xylitol nasal irrigation was useful in postoperative ESS and septoplasty care. For patients with allergic sensitization, rhinorrhea showed greater improvement in the xylitol group than in the saline group.

Abstract
OBJECTIVES The use of greater palatine canal (GPC) injections of a local anesthetic and a vasoconstrictor to decrease surgical bleeding during endoscopic sinus surgery (ESS) is controversial. We investigated the role of a preoperative GPC injection to minimize intraoperative bleeding during ESS in patients with chronic sinusitis through a meta-analysis of the relevant literature. DATA SOURCES PubMed, SCOPUS, and the Cochrane database. REVIEW METHODS We screened the relevant literature published before May of 2018. Five articles that compared the pre-operative GPC injection (treatment group) with a placebo or no treatment (control group) were included for this analysis of the outcomes, which included an endoscopic grade of nasal bleeding and intraoperative hemodynamic stability during ESS. RESULTS The endoscopic grade in the treatment group was significantly reduced when compared with the control group. No significant adverse effects were reported in the enrolled studies. The subgroup analyses of these results compared the concentrations of adrenalin (1:80,000 or 1:100,000), and adrenalin 1:80,000 showed significant effects on intraoperative bleeding when compared to adrenalin 1:100,000. CONCLUSION This study demonstrated that GPC injections of local anesthesia with 1:80,000 adrenaline for ESS effectively reduced intraoperative bleeding. Additionally, this procedure showed no significant adverse effects, such as hemodynamic instability. However, the standardized dosing needs further investigation and more trials.

Abstract
BACKGROUND Exposure to urban particulate matter (UPM) has been linked to aggravation of various health problems. Although the effects of UPM on the lower respiratory tract have been extensively studied, more research is required on the impact of UPM on the upper respiratory tract and the underlying mechanisms. Thus, we investigated the cytotoxic effects of UPM on cultured human nasal fibroblasts, the underlying signaling pathways involved, and changes in cytokine levels. METHODS Human turbinate tissue specimens were collected during partial turbinectomies performed on 6 patients, and then cultured. The effect of UPM on nasal fibroblast viability was explored. Real-time reverse transcription-polymerase chain reaction was used to measure the mRNA levels of genes encoding cytokines and chemokines (interleukin [IL]-4, IL-6, IL-8, and tumor necrosis factor-α) before and after 24 hours of UPM treatment. Enzyme-linked immunosorbent assays were employed to measure IL-6 and IL-8 levels. The status of the p38 and nuclear factor (NF)-κB signaling pathways was analyzed by Western blotting. RESULTS UPM reduced cell viability in a dose-dependent manner and increased IL-6 and IL-8 expression at both the mRNA and protein levels. UPM induced the phosphorylation of p38 and NF-κB p65; inhibitors of the actions of these proteins repressed phosphorylation and the expression of IL-6 and IL-8. CONCLUSION UPM induced IL-6 and IL-8 expression by fibroblasts via p38 and NF-κB classical signaling, suggesting that UPM can induce or aggravate allergic and/or chronic rhinitis.

Abstract
Objective This article describes the role played by endoscopic endonasal transsphenoidal approach (EETSA) to the sphenoidal process of the septal cartilage of a deviated nasal septum. Design Case series with chart review. Setting Tertiary referral center. Participants Between 2009 and 2016, 177 patients with skull base tumors who underwent EETSA were included. Main Outcome Measures In 8 cases, the conventional two nostrils-four hands technique was employed (group A). In 16 cases, we placed a right-side conventional nasoseptal flap and a left-side modified nasoseptal rescue flap (group B), and in 153 cases, bilateral modified nasoseptal rescue flaps (group C). The number of septoplasty-required cases and the change of nasal cavity area differences reflecting septal deviation were measured. Results Septoplasty during EETSA was performed in two cases: one from group B and one from group C. There was no significant difference in the ratio of septoplasty-required cases among the three groups ( p = 0.127). Between pre- and postoperative nasal cavity, the cross-sectional area difference at the anterior end of the middle turbinate level significantly decreased ( p = 0.045). Also, the angle of deviation at the level of ostiomeatal unit significantly decreased after EETSA ( p < 0.001). Conclusion Separation of a deviated complex surrounding the sphenoidal process of the septal cartilage is the key to relieving a deviated nasal septum. EETSA combined with the two nostrils-four hands technique allows posterior septectomy (including removal of this deviated complex) to be performed. Thus, EETSA may commence without preceding septoplasty even in cases with severe nasal septum deviations.

Abstract
OBJECTIVE We sought to examine the utility of an endoscopic transseptal approach and creation of a bilateral nasoseptal flap using a 2-nostrils/4-hands technique in patients with challenging skull-base tumors. METHODS The medical records of patients operated on via an endoscopic transseptal approach between 2009 and 2017 were retrospectively reviewed. Two patients with ossifying fibroma, 2 with orbital hemangioma, 2 with trigeminal nerve schwannoma, and 1 patient each with juvenile angiofibroma, meningioma, and myxofibrosarcoma were included in the study. The surgical technique and endoscopic anatomy are presented. RESULTS The mean age of the 4 male and 5 female patients was 39.9 ± 14.8 years. By using this technique, all 7 tumors were resected with minimal nasal morbidity after a mean follow-up of 15.2 ± 9.4 months. CONCLUSIONS The endoscopic transseptal approach, by creation of a bilateral nasoseptal flap using a 2-nostrils/4-hands technique, improves surgical visualization and increases instrument maneuverability. Surgical access to challenging skull-base tumors is therefore afforded. The procedure also reduces nasal morbidity by preserving the lacrimal apparatus and anterior maxilla structures and avoiding septal perforation and traumatic nose traction.

Abstract
OBJECTIVE To investigate a potential correlation between changes in voice and changes in nasal volume. METHODS The endoscopic endonasal transsphenoidal approach (EETSA) was performed on 120 patients between February 2009 and August 2016 by using the bilateral modified nasoseptal rescue flaps method. All the patients were subjected to pre- and postoperative paranasal computed tomography (CT) and voice evaluations by using acoustic analyses, a nasometer to measure the nasalance, and determination of the voice handicap index (VHI). Paranasal CT and the medical image processing software were used to calculate changes in nasal cavity volume in three nasal sections. RESULTS Enlargement of the nasal cavity after surgery was evident in all three areas (anteronasal, p < 0.001; midnasal, p = 0.005; postnasal, p = 0.025). In addition, EETSA resulted in significantly higher mean nasalance scores for the oronasal passage (p < 0.001) and nasal passage (p < 0.001); more frequency perturbation (jitter) (p < 0.001) and amplitude perturbation (shimmer) (p < 0.001); and higher grade, roughness, breathiness, asthenia, and strain scores (p < 0.001), and VHI (p = 0.01). However, only changes in the nasal volume after EETSA correlated with postnasal hypernasality (r = 0.2; p = 0.029). CONCLUSION Although changes in nasal volume, voice, and speech may develop after EETSA, we found that changes in nasal volume were not correlated with changes in any voice-quality measure. However, the postnasal cavity was the region most dramatically affected by EETSA, and postnasal volume changes after surgery may be associated with hypernasal speech.

Abstract
Background Allergic rhinitis (AR) and rhinosinusitis (RS) negatively impact psychological well-being and health-related quality of life (HRQoL). However, few population-based studies have investigated the effects of these conditions on mental health and HRQoL. Purpose To explore independent associations of AR and/or RS with mental health and HRQoL using data from the 2013–2015 Korea National Health and Nutrition Examination Survey (KNHANES). Methods The KNHANES is a nationwide cross-sectional survey of the non-institutionalized population of Korea. A total of 15,441 adults completed the clinical examination and the health questionnaire. We divided all participants into four groups: AR-/RS-, AR-/RS+, AR+/RS-, and AR+/RS+. Logistic regression analyses were performed after adjustment for sociodemographic characteristics, general health behaviors, and other comorbidities. Results The AR+/RS+ group contained the highest proportion of subjects with perceived stress and depressed mood. Subjects with AR+/RS+ also had more frequent problems in terms of pain/discomfort and anxiety/depression. After adjusting for all confounders, the odds ratios (ORs) were 2.96 (p = 0.009) for depressed mood and 3.17 (p = 0.013) for suicidal ideation in the AR+/RS+ group compared with in the AR-/RS- group. The AR+/RS- group reported more perceived stress (OR, 1.56, p = 0.003) and depression (OR, 1.72, p = 0.024) compared with the AR-/RS- group. In terms of the ORs for HRQoL, the AR+/RS+ group reported more problems in terms of self-care (OR, 3.73, p = 0.038) and more pain/discomfort (OR 2.19, p = 0.006) compared with the AR-/RS- group. Conclusions In the Korean population, AR and RS exerted a synergistic negative impact on mental health and HRQoL, especially suicidal ideation. Most patients seek help from clinicians for impaired HRQoL. Therefore, clinicians should consider the underlying mental health and HRQoL of patients with AR and/or RS, as these may be impaired by their conditions.

Abstract
Introduction The purpose of this study was to examine the number of publications by South Korean emergency physicians in highly cited journals and the increase in their numbers. It also sought to assess the impact factors of such publications. Methods The present study was a retrospective quantitative literature review of the publications by South Korean emergency physicians from 1996 to 2011 in the category of “emergency medicine” in the science edition of Journal Citation Reports 2011. We analysed the total number of articles published by South Korean emergency physicians and their impact factors. Results Between 1996 and 2011, the number of South Korean board-certified emergency physicians increased from 51 to 958, and 230 articles were published in 14 highly cited journals. The total impact factor (IF) of the original articles published during that period was 227.86, and the mean IF was 1.93. More than 10 articles had been published annually in the past 5 years in highly cited journals and there were over 400 South Korean board-certified emergency physicians. Conclusions Emergency medicine in South Korea started about 20 years ago, but academic productivity, indicated by at least ten articles annually in highly cited journals, was only achieved in the last five years. The mean IF of these articles was similar to that in other highly productive countries. (Hong Kong j.emerg.med. 2014;21:205-212)

Abstract
Introduction Our purpose was to evaluate whether plain abdominal radiography (PAR) could accurately differentiate between small bowel obstruction (SBO) and small bowel ileus (SBI) in an emergency setting. We also evaluated the value of known classic signs on the PAR for differentiating between SBO and SBI. Methods This retrospective study included 216 emergency room patients who had small bowel distension (maximal small bowel diameter ≥2.5 cm) on the PAR and who underwent successive abdominal computed tomography. One radiologist and one emergency physician retrospectively reviewed PAR in consensus, unaware of the patients' clinical data; they divided the patients into an SBO group and an SBI group according to the radiographic findings. Presence or numeric values of 10 radiographic signs were also recorded. Final diagnoses of SBO and SBI were established by a combined analysis of medical charts, surgical records, radiographic findings on abdominal computed tomography, and small bowel studies. The differential diagnoses based on PAR and the final diagnoses were compared, and the sensitivity and specificity of PAR were calculated. We also evaluated the differences among 10 radiographic signs between the final SBO and SBI groups. Results Sensitivity and specificity of PAR for SBO were 82.0% and 92.4%, respectively. Among the 10 radiographic signs, all except maximal colon diameter were statistically significant predictors on the final diagnosis. Conclusions PAR is an accurate and effective initial imaging modality for differentiating between SBO and SBI in an emergency setting, and most of the classic radiographic signs have a diagnostic value.

Abstract
Background Biofilms were the third-dimensional structure in the solid surface of bacteria. Bacterial biofilms were difficult to control by host defenses and antibiotic therapies. Escherichia coli (E. coli) and Salmonella were popular pathogenic bacteria that live in human and animal intestines. Essential oils are aromatic oily liquids from plant materials and well known for their antibacterial activities. Method This study was conducted to determine effect of essential oil on anti-biological biofilm formation of E. coli and Salmonella strains in in vitro experiment. Two kinds of bacterial strains were separated from 0.2 g pig feces. Bacterial strains were distributed in 24 plates per treatment and each plates as a replication. The sample was coated with a Bacterial biofilm formation was. Result Photographic result, Escherichia coli (E. coli) and Salmonella bacteria colony surface were thick smooth surface in control. However, colony surface in blended and single essential oil treatment has shown crack surface layer compared with colony surfaces in control. Conclusion In conclusion, this study could confirm that essential oils have some interesting effect on anti-biofilm formation of E. coli and Salmonella strains from pig feces.

Abstract
Small bowel injury can occur as the result of a multifaceted process that includes increased acid secretion, generation of reactive oxygen species, and cyclooxygenase inhibition. However, no effective medication for small bowel ulceration is available. Simvastatin is an important lipid-lowering agent with anti-inflammatory activity. We aimed to validate the effects of simvastatin in vitro and in vivo. In presence or absence of simvastatin, IEC-6 small bowel cell line with 50 ng/ml of tumor nectosis factor α (TNF-α) was investigated by western blotting, qRT-PCR, and DCF-DA assay. In addition, an in vivo study of nonsteroidal anti-inflammatory drugs (NSAID)-induced small bowel inflammation was performed using 7-week-old specific-pathogen-free (SPF) male C57BL/6 mice. Simvastatin treatment reduced the mRNA levels of interleukin-6 and interleukin-8 by approximately 50% in TNF-α-stimulated IEC-6 cells. Treatment with a combination of 50 ng/ml TNF-α and μM simvastatin decreased activation of Akt, IκBα, and nuclear factor-κB p65 level in IEC-6 cells. By DCF-DA staining, intracellular reactive oxygen species (ROS) production was increased in TNF-α-stimulated cells, and treatment with simvastatin decreased the level of ROS. In addition, in vivo mouse model of NSAID-induced small bowel inflammation, the administration of simvastatin reduced the number of small bowel hemorrhagic lesions and the level of ROS production as determined by gross examination and 8-hydroxydeoxyguanosine immunohistochemistry of small bowel tissue, respectively. Simvastatin reduced NSAID-induced injuries by both suppression of ROS generation and modulation of inflammatory cytokines in vitro and in vivo. Therefore, simvastatin, an HMG-CoA reductase inhibitor, has potential as a prophylactic and therapeutic agent for NSAID-induced small bowel injury.

Abstract
Objective We evaluated the severity of olfactory impairment according to risk factors, compared responses with risk factors and treatment timing, and investigated prognosis according to treatments. Study design Case series with chart review. Setting Tertiary referral center. Subjects and Methods We retrospectively reviewed medical records of patients complaining of loss of their sense of smell between January 2006 and May 2016. In total, 491 patients were included. We evaluated olfactory function using the Connecticut Chemosensory Clinical Research Center test (threshold test) and Cross-cultural Smell Identification Test. Results Post-upper respiratory infection patients showed better results than those with other risk factors (59.6% recovered). Patients with head trauma (12.5% recovered) and congenital olfactory dysfunction (0% recovered) showed poorer results. Earlier treatment showed better olfactory recovery outcomes for post-upper respiratory infection ( P = .001), head trauma ( P = .022), and nasal/sinus surgery ( P = .009). Xerostomia ( P = .73) and idiopathy ( P = .365) showed no significant difference in terms of treatment timing. The threshold test better reflected subjective recovery than the identification test. The systemic + topical steroid group and the systemic steroid treatment group both showed better smell recovery outcomes than the group with topical treatment alone (both, P < .001). However, there was no significant difference between the systemic treatment group and the systemic + topical treatment group ( P = .978). Conclusions Our findings suggest that the duration of smell loss is important for better olfactory outcomes with most etiologies. Also, the effects of systemic steroids were better than those of topical steroids, regardless of combined treatment.

Abstract
Objective To describe the clinical features of invagination of the sphenoid sinus mucosa (ISM) and compare them with other similar cases using a visual analog scale (VAS) to assess the various nasal symptoms and to discuss its clinical significance and means of prevention. Study Design Retrospective chart review at a tertiary referral center. Methods Between 2010 and 2015, 8 patients who had undergone EETSA surgery displayed postoperative ISM. The comparison group consisted of 147 patients who underwent the same surgical procedures and were diagnosed with the same diseases. Pre- or postoperative paranasal sinus computed tomography (PNS CT) and VAS were performed and subsequently analyzed. Results The clinical features of ISM of the sphenoid sinus showed sellar floor invagination and regenerated inverted ingrowing sphenoid mucosa on endoscopic imaging. PNS CT also showed a bony defect and invaginated air densities at the sellar turcica. Pre- and postoperative VAS scores revealed that the ISM group had much less of an improvement in headaches after surgery than that of the comparison group (p = 0.049). Conclusion ISM may occur because of a change in pressure, sphenoid mucosal status, or arachnoid membrane status. Moreover, ISM is related to improvements in headaches. Therefore, EETSA patients should avoid activities that cause rapid pressure changes during the healing process. In addition, sellar reconstruction that is resistant to physical pressure changes should be mandated despite the absence of an intraoperative CSF leak.

Abstract
WHAT IS KNOWN AND OBJECTIVE This study aimed to compare the ability of statin monotherapy (ST group), omega-3 fatty acid monotherapy (OM_A group) and combination therapy with omega-3 fatty acids and a statin (OM_S group), to reduce triglyceride (TG) levels in patients with hypertriglyceridaemia. METHODS In this retrospective cohort study, we extracted data from the electronic medical records of patients initially prescribed either a statin or omega-3 fatty acids between January, 2009 and December, 2013. We performed a comparative analysis of the change in cholesterol levels between baseline and an average of 3 months later. RESULTS AND DISCUSSION Data were extracted for 2071 patients. The average daily eicosapentaenoic acid (EPA) ethyl ester and docosahexaenoic acid (DHA) ethyl ester intake was 1689 mg, and 79-86% of the OM_A and OM_S groups were prescribed two omega-3 fatty acid capsules. At a baseline TG level of between 200 and 500 mg/dL, TG levels were reduced by 16 ± 2·8% in the ST group, 28 ± 2·8% in the OM_A group and 29 ± 2·3% in the OM_S group (P = 0·001 for ST group vs. OM_A and OM_S groups), with no difference between the OM_A and OM_S groups. At a baseline TG level ≥500 mg/dL, there was no difference in TG level reduction between the three groups (54 ± 7·3%, 55·8 ± 3·5% and 51·8 ± 6·8%, respectively, P = 0·851). WHAT IS NEW AND CONCLUSION Although omega-3 fatty acids are not considered the primary medication for hypertriglyceridaemia, the prescription of omega-3 fatty acids is justifiable if reduction in TG levels is judged to be necessary.

Abstract
The ability to visualize whole-brain vasculature is important for quantitative in vivo investigation of vascular malfunctions in cerebral small vessel diseases, including cancer, stroke and neurodegeneration. Transverse relaxation-based ΔR2 and ΔR2 * MR angiography (MRA) provides improved vessel-tissue contrast in animal deep brain with the aid of intravascular contrast agents; however, it is susceptible to orientation dependence, air-tissue interface artifacts and vessel size overestimation. Dual-mode MRA acquisition with superparamagnetic iron oxide nanoparticles (SPION) provides a unique opportunity to systematically compare and synergistically combine both longitudinal (R1 ) and transverse (ΔR2 and ΔR2 *) relaxation-based MRA. Through Monte Carlo (MC) simulation and MRA experiments in normal and tumor-bearing animals with intravascular SPION, we show that ultrashort TE (UTE) MRA acquires well-defined vascularization on the brain surface, minimizing air-tissue artifacts, and combined ΔR2 and ΔR2 * MRA simultaneously improves the sensitivity to intracortical penetrating vessels and reduces vessel size overestimation. Consequently, UTE-ΔR2 -ΔR2 * combined MRA complements the shortcomings of individual angiograms and provides a strategy to synergistically merge longitudinal and transverse relaxation effects to generate more robust in vivo whole-brain micro-MRA.

Abstract
WHAT IS KNOWN AND OBJECTIVE Higher rate of statin-related hepatotoxicity has been reported for Koreans than for Westerners. Moreover, statin-related aminotransferase elevation for those who show borderline levels of aspartate transaminase (AST) and alanine transaminase (ALT) (≤×3 of UNL) at baseline has not been fully investigated. METHODS Post-statin changes AST/ALT levels during the first year for 21 233 Korean outpatients at two large academic teaching hospitals from January 2009 to December 2013 were analysed using electronic health record data. The date of the first statin prescription was set as baseline. We also performed a comparative analysis of statin-related AST/ALT elevations according to the type of statin, followed by an analysis of clinical risk factors. RESULTS AND DISCUSSION The progression rate to abnormal AST/ALT values [>×3 the upper normal limit (UNL)] was significantly higher (2·4-16% vs. 0·3-1·7%, P < 0·001) in subjects with borderline (>×1, but ≤×3 of UNL) compared with normal AST/ALT values at baseline. Those with normal baseline AST/ALT did not show significantly different progression rate between different statin medications (P = 0·801). However, patients taking pitavastatin (HR = 0·76, P = 0·657) were least likely to develop abnormal AST/ALT, whereas those taking fluvastatin (HR = 2·96, P = 0·029) were the most likely to develop abnormal AST/ALT compared with atorvastatin for patients who were with baseline borderline AST/ALT. However, given the small sample sizes and the observational nature of our study, these need further study. WHAT IS NEW AND CONCLUSION It is advisable to regularly monitor AST/ALT levels even in patients with AST/ALT increases >×1. Future studies should aim to determine the possible risk factors for each specific statin type by analysing various confounding variables.

Abstract
OBJECTIVE We evaluated postoperative changes in nasal cavity volume and their effects on nasal function and symptoms after endoscopic endonasal transsphenoidal approach for antero-central skull base surgery. STUDY DESIGN Retrospective chart review at a tertiary referral center. METHODS We studied 92 patients who underwent binostril, four-hand, endoscopic endonasal transsphenoidal approach surgery using the bilateral modified nasoseptal rescue flap technique. Pre- and postoperative paranasal computed tomography and the Mimics® program were used to assess nasal cavity volume changes at three sections. We also performed several pre- and postoperative tests, including the Connecticut Chemosensory Clinical Research Center test, Cross-Cultural Smell Identification Test, Nasal Obstruction Symptoms Evaluation, and Sino-Nasal Outcome Test-20. In addition, a visual analog scale was used to record subjective symptoms. We compared these data with the pre- and postoperative nasal cavity volumes. RESULTS Three-dimensional, objective increases in nasal passage volumes were evident between the inferior and middle turbinates (p<0.001) and between the superior turbinate and choana (p = 0.006) postoperatively. However, these did not correlate with subjectively assessed symptoms (NOSE, SNOT-20 and VAS; all nasal cavity areas; p≥0.05) or olfactory dysfunction (CCCRC and CCSIT test; all nasal cavity areas; p≥0.05). CONCLUSION Skull base tumor surgery via an endoscopic endonasal transsphenoidal approach altered the patients' nasal anatomy, but the changes in nasal cavity volumes did not affect nasal function or symptoms. These results will help surgeons to appropriately expose the surgical field during an endoscopic endonasal transsphenoidal approach.

Abstract
OBJECTIVE We evaluated postoperative changes in nasal cavity dimensions and their effects on nasal functions and symptoms. STUDY DESIGN Case series with chart review. SETTING Tertiary referral center. SUBJECTS AND METHODS We studied patients who underwent binostril, 4-hand endoscopic endonasal transsphenoidal approach surgery with the bilateral modified nasoseptal rescue flap technique. Pre- and postoperative paranasal computed tomography scans were used to assess nasal cavity dimensional changes at 4 levels. We also performed several pre- and postoperative tests, including the Connecticut Chemosensory Clinical Research Center test and the Cross-Cultural Smell Identification Test (n = 119) to evaluate olfactory functions. Also, the Nasal Obstruction Symptoms Evaluation, the Sino-Nasal Outcome Test-20, and a visual analog scale were used (n = 157) to record subjective symptoms. We compared these data with the pre- and postoperative nasal cavity dimensions. RESULTS Two-dimensional objective increases in nasal passage dimensions were evident postoperatively (all cross-sectional areas, P < .001, except choana and left inferior turbinate). However, these did not correlate with subjectively assessed symptoms (Nasal Obstruction Symptoms Evaluation, all cross-sectional areas, P ≥ .05, except right middle turbinate; Sino-Nasal Outcome Test-20, all cross-sectional areas, P ≥ .05) or olfactory dysfunction evaluated with the Connecticut Chemosensory Clinical Research Center test (all cross-sectional areas, P ≥ .05) or the Cross-Cultural Smell Identification Test (all cross-sectional areas, P ≥ .05). CONCLUSION Endoscopic endonasal transsphenoidal approach surgery altered the patients' nasal anatomy, but the changes in nasal cavity dimensions did not affect nasal functions and symptoms. These results will help surgeons to appropriately expose the surgical field during endoscopic endonasal transsphenoidal approach surgery.

Abstract
WHAT IS KNOWN AND OBJECTIVE There is a disparity between the Korean treatment guidelines and actual clinical prescription habits. This study was designed to evaluate the department-specific disparities and achievement rates for low-density lipoprotein cholesterol (LDL-C) targets, based on each department's specific statin prescription patterns. METHODS We retrospectively evaluated data from 31 718 patients who had been prescribed a statin at least once between January 2008 and June 2013 at our institution. Patients were classified into the high-risk (target LDL-C < 100 mg/dL) or moderate-risk (target LDL-C < 130 mg/dL) groups, according to the National Cholesterol Education Programme-Adult Treatment Panel III guidelines. RESULTS AND DISCUSSION Statins were most commonly prescribed in the cardiology (32·0%) and endocrinology (26·6%) departments. For the high-risk group, 70% of patients in the cardiology, endocrinology and cardiac surgery departments achieved their target LDL-C levels (<100 mg/dL). However, the target achievement rates in most other departments were <70%. For the moderate-risk group, 79·2% of patients achieved their target levels. Departments that prescribed a greater number of high- or intermediate-potency statins were more likely to achieve their target LDL-C levels. The group that achieved their target LDL-C levels (<100 mg/dL) exhibited a significant positive relationship (Spearman's correlation coefficient = 0·8571, P = 0·0065), from low to high potency. WHAT IS NEW AND CONCLUSION Some departments tend to undertreat when prescribing statins. However, to reach to the target LDL-C levels, physicians must overcome their tendency to undertreat with statins. We believe that the target achievement rate will increase if doctors are more actively aware of a patient's individual status and related risk factors before prescribing statins.

Abstract
BACKGROUND Clinical factors were previously identified as predictors of short-term treatment efficacy in Crohn's disease (CD). The PRECiSE 3 (P3) 7-year trial provides an opportunity to study predictors of short- and long-term clinical remission among CD patients treated with certolizumab pegol (CZP). AIM To identify factors that influence long-term remission of CD with CZP treatment. METHODS Patients who had completed placebo-controlled studies (PRECiSE 1/PRECiSE 2, P1/P2) enrolled in P3 and received open-label CZP 400 mg every 4 weeks up to 7 years. Baseline predictors included, but were not limited to, smoking status, disease duration, prior inflammatory bowel disease (IBD) surgery, Harvey-Bradshaw Index (HBI), albumin, haematocrit and CZP exposure; association with time to initial remission (HBI ≤4) was tested for patients who received CZP in P1/P2; time to loss of remission/frequency of maintenance of remission was also tested. Univariate analyses and multivariate Cox or logistic regression models were used. RESULTS Predictors for initial remission (N = 377) included age, haematocrit, prior IBD surgery and entry HBI (P < 0.05 for all). Predictors for loss of remission (N = 437) included HBI, serum albumin concentration, haematocrit, smoking status and exposure. Predictors of maintenance of remission (N = 437) included haematocrit, IBD surgery, HBI, disease duration, serum albumin concentration and exposure. Significant predictors were confirmed with stepwise multivariate regression models. CONCLUSIONS These analyses identified several influential parameters for short-and long-term remission of Crohn's disease with certolizumab pegol treatment. The data yield valuable hypotheses regarding factors that influence certolizumab pegol treatment. More investigation is needed. (ClinicalTrials.gov identifier NCT00552058).
