Abstract
BACKGROUND Because repeat hepatectomy for recurrent hepatocellular carcinoma is a potentially invasive procedure, it is necessary to identify patients who truly benefit from repeat hepatectomy. Albumin-bilirubin grading has been reported to predict survival in patients with hepatocellular carcinoma. However, as prognosis also depends on tumor factors, a staging system that adds tumor factors to albumin-bilirubin grading may lead to a more accurate prognostication in patients with recurrent hepatocellular carcinoma. METHODS Albumin-bilirubin grading and serum alpha-fetoprotein levels were combined and the albumin-bilirubin-alpha-fetoprotein score was created ([albumin-bilirubin grading = 1; 1 point, 2 or 3; 2 points] + [alpha-fetoprotein<75 ng/mL, 0 points; ≥5, 1 point]). Patients were classified into three groups, and their characteristics and survival were evaluated. The predictive ability of the albumin-bilirubin-alpha-fetoprotein score was compared with that of the Cancer of the Liver Italian Program and the Japan Integrated Stage scores. RESULTS Albumin-bilirubin-alpha-fetoprotein score significantly stratified postoperative survival (albumin-bilirubin-alpha-fetoprotein score = 1/2/3: 5-year recurrence-free survival [%]: 22.4/20.7/0.0, p < 0.001) and showed the highest predictive value for survival among the integrated systems (albumin-bilirubin-alpha-fetoprotein score/Japan Integrated Stage/Cancer of the Liver Italian Program: 0.785/0.708/0.750). CONCLUSIONS Albumin-bilirubin-alpha-fetoprotein score is useful for predicting the survival of patients with recurrent hepatocellular carcinoma undergoing repeat hepatectomy.

Abstract
BACKGROUND Although several recent meta-analyses have investigated the clinical influence of the addition of lateral lymph node dissection (LLND) on oncologic outcomes in patients with mid-low rectal cancer (RC) undergoing mesorectal excision (ME), most studies included in such meta-analyses were retrospectively designed. Therefore, this study aimed to explore the clinical influence of prophylactic LLND on oncologic outcomes in patients with mid-low RC undergoing ME. METHODS A comprehensive electronic search of the literature up to July 2022 was performed to identify studies that compared oncologic outcomes between patients with mid-low RC undergoing ME who underwent LLND and patients with mid-low RC undergoing ME who did not undergo LLND. A meta-analysis was performed using fixed-effects models and the generic inverse variance method to calculate hazard ratios (HRs) and 95% CIs, and heterogeneity was analyzed using I2 statistics. RESULTS A total of 6 studies, consisting of 3 randomized and 3 propensity score matching studies, were included in this meta-analysis. The results of the meta-analysis of 2 randomized studies demonstrated no significant effect of prophylactic LLND on improving oncologic outcomes concerning overall survival (OS) (HR, 1.22; 95% CI, 0.89-1.69; I2 = 0%; P = .22) and relapse-free survival (RFS) (HR, 1.03; 95% CI, 0.81-1.31; I2 = 28%; P = .83). CONCLUSION The results of this meta-analysis revealed no significant influence of prophylactic LLND on oncologic outcomes-OS and RFS-in patients with mid-low RC who underwent ME.

Abstract
BACKGROUND Despite the accumulating evidence regarding the oncological differences between nonalcoholic fatty liver disease (NAFLD)-related hepatocellular carcinoma (HCC) and viral infection-related HCC, the short- and long-term outcomes of surgical resection of NAFLD-related HCC remain unclear. While some reports indicate improved postoperative survival in NAFLD-related HCC, other studies suggest higher postoperative complications in these patients. METHODS Patients with NAFLD and those with hepatitis viral infection who underwent hepatectomy for HCC at our department were retrospectively analyzed. The clinical, surgical, pathological, and survival outcomes were compared between the two groups. RESULTS Among the 1047 consecutive patients who underwent hepatectomy for HCC, 57 had NAFLD-related HCC (NAFLD group), and 727 had virus-related HCC (VH group). The body mass index and serum glycated hemoglobin levels were significantly higher in the NAFLD group than in the VH group. There were no significant differences in operative time and bleeding amount. Moreover, the morbidity and the length of postoperative hospital stays were similar across both groups. The pathological results showed that the tumor size was significantly larger in the NAFLD group than in the VH group. No significant differences between the groups in overall or recurrence-free survival were found. In a subgroup analysis with matched tumor diameters, patients in the NAFLD group had a better prognosis after hepatectomy than those in the VH group. CONCLUSION Surgical outcomes after hepatectomy were comparable between the groups. Subgroup analysis reveals early detection and surgical intervention in NAFLD-HCC may improve prognosis.

Abstract
Objectives Stoma outlet obstruction (SOO) occurs with an incidence of approximately 40% after proctocolectomy for Ulcerative colitis (UC) with diverting ileostomy. This study aimed to identify the risk factors for SOO after proctocolectomy with diverting ileostomy for patients with UC. Methods We reviewed the data of 68 patients with UC who underwent proctocolectomy and diverting ileostomy between April 2006 and September 2021. These cases were analyzed on the basis of clinicopathological and anatomical factors. SOO was defined as small bowel obstruction displaying symptoms of intestinal obstruction, such as abdominal distention, abdominal pain, insertion of a tube through the stoma. Results The study included 38 (56%) men and 30 (44%) women with a median age of 42 years (range, 21-80). SOO categorized as at least Clavien-Dindo grade II occurred in 11 (16%) patients. Six patients required earlier stoma closure than scheduled. Compared with patients without SOO, patients with SOO had a significantly higher total steroid dose from the onset of UC to surgery (p = 0.02), a small amount of intraabdominal fat (p = 0.04), and a higher rate of laparoscopic surgery (p < 0.01). Conclusions A high preoperative steroid dose, a small amount of intraabdominal fat and laparoscopic surgery were identified as risk factors for SOO. Early detection and treatment for SOO are important for patients at risk.

Abstract
BACKGROUND Patients with pan-peritonitis (PP) due to colorectal perforation have high mortality rate because colorectal perforation causes septic shock. The association between total steroid intake (TSI) and hospital mortality of such patients is not clear. METHODS One hundred forty-two patients who underwent surgery for PP due to colorectal perforation were reviewed. Patients were divided into two groups by 8000 mg of TSI. The cut-off value of TSI was determined using a receiver operating characteristic curve for hospital mortality. RESULTS The cut-off value of TSI for hospital mortality was 8000 mg. Patients with TSI>8000 mg had high rate of hemodialysis, hospital mortality, and elevated neutrophil ratio (>95%) compared with those with TSI≤8000 mg. Multivariate analyses revealed that TSI (>8000/≤8000, mg) (OR, 9.669; 95% CI, 1.011-92.49; P = .049) was significantly associated with hospital mortality as well as bleeding volume (>1000/≤1000, mL) (OR, 26.08; 95% CI, 3.566-190.4; P = .001), lymphocyte ratio (≤4/>4, %) (OR, 7.988; 95% CI, 1.498-42.58; P = .015) and C-reactive protein (≤7.5/>7.5, mg/dL) (OR, 41.66; 95% CI, 4.784-33.33; P = .001). DISCUSSION There was a significant association between TSI and hospital mortality in patients with PP due to colorectal perforation as well as intraoperative bleeding and systemic inflammatory markers.

Abstract
OBJECTIVE To explore the influence of the no-touch isolation technique (NTIT) on oncologic outcomes for patients with colon cancer (CC) undergoing curative surgery. BACKGROUND Although several studies have investigated this topic, there have been no meta-analyses exploring the influence of NTIT on oncologic outcomes for these patients. METHODS We performed a comprehensive electronic literature search of studies published prior to March 2022 to identify those that compared oncologic outcomes for patients with CC who did or did not undergo NTIT. We conducted a meta-analysis using a random-effects model to calculate risk ratio (RRs) and 95% confidence intervals (CIs), analyzing heterogeneity using I2 statistics. RESULTS Four studies involving a total of 2885 patients with CC who underwent curative surgery met the inclusion criteria for this meta-analysis. The 5-year overall survival (OS) rate was 76.6% for patients with CC who underwent NTIT and 77.2% for those who did not. A meta-analysis of the 3 studies that reported 5-year OS revealed no significant difference between groups (RR, 0.84; 95% CI, 0.62-1.16; P = 0.30; I2 = 70%). In addition, there were no significant differences in 5-year recurrence-free survival (RR, 1.17; 95% CI, 0.93-1.48; P = 0.19; I2 = 45%), and 5-year liver recurrence-free survival (RR, 0.95; 95% CI 0.62, 1.46; P = 0.82; I2 = 65%). CONCLUSIONS The use of NTIT has no significant influence on oncologic outcomes for patients with CC undergoing curative surgery.

Abstract
BACKGROUND/AIM Fluoropyrimidine therapy or oxaliplatin combination therapy is recommended for patients with stage III colorectal cancer as adjuvant chemotherapy (AC). However, the criterion for selecting these regimens is still unclear in patients with stage III rectal cancer (RC). In order to select an appropriate regimen of AC for such patients, it is needed to identify characteristics associated with tumor recurrence. PATIENTS AND METHODS The records of 45 patients with stage III RC undergoing AC using tegafur-uracil/leucovorin (UFT/LV) were retrospectively reviewed. The cut-off value of characteristics was determined using a receiver operating characteristic curve for recurrence. Univariate analyses using Cox-Hazard model for predicting recurrence were performed with clinical characteristics. Survival analysis was performed using Kaplan-Meier method and log-rank test. RESULTS Thirty patients (66.7%) completed AC using UFT/LV. Fifteen patients (33.3%) did not complete AC because of adverse events, tumor recurrence and others. Sixteen patients (35.6%) had recurrence. Univariate analyses revealed that lymph node metastasis (N2/N1) (p=0.002) was associated with tumor recurrence. Survival analysis showed that lymph node metastasis (N2/N1) could stratify recurrence-free survival (p<0.001). CONCLUSION N2 lymph node metastasis can predict tumor recurrence in patients with stage III RC undergoing AC using UFT/LV.

Abstract
Malignant mesothelioma (MM) is uncommon in cats and dogs and can be challenging to diagnose. Adequate tissue sampling is required for superior diagnostic accuracy. Protoporphyrin IX, a metabolite of 5-aminolaevulinic acid (5-ALA), is a photosensitiser for photodynamic diagnosis (PDD). To the best of our knowledge, no study has reported the use of 5-ALA-PDD to detect MM in veterinary medicine. The present study describes the use of 5-ALA-PDD for MM diagnosis in a cat and dog, as well as the effectiveness of intracavitary chemotherapy. We evaluated the use of PDD with 5-ALA hydrochloride (5-ALA-PDD) in two cases of MM. A 12-year-old cat presented with a 1-month history of respiratory distress, and a 9-year-old dog presented with a 3-month history of mild abdominal distention. We endoscopically biopsied lesions in both the cases using 5-ALA-PDD. Histopathological examination revealed mesothelioma, and immunohistochemical staining was positive for calretinin. Both patients were treated with carboplatin. The cat died of respiratory failure. Although, the dog's condition improved 21 days after the first chemotherapeutic drug administration, the dog died on day 684 owing to cardiac-related issues. 5-ALA-PDD is thus, safe and feasible for the diagnosis of MM in veterinary medicine.

Abstract
Background Tibial nerve stimulation therapy is a treatment option for an overactive bladder. A surface electrode called a Silver Spike Point® electrode, which does not directly puncture the skin as in transcutaneous tibial nerve stimulation, but is expected to exert the same therapeutic effect as percutaneous tibial nerve stimulation, was developed. This study investigated the efficacy and safety of tibial nerve stimulation with Silver Spike Point® electrodes for refractory overactive bladder. Methodology This was a six-week, single-arm, prospective study on the efficacy and safety of transcutaneous tibial nerve stimulation for patients with refractory overactive bladder. Each treatment lasted 30 minutes and was performed twice a week. The stimulation sites of the tibial nerve were the Sanyinjiao point (SP6) and Zhaohai point (KI6) in both legs. The primary endpoint was the change in the total overactive bladder symptom score. Results In total, 29 patients (20 males and nine females: 64.86 ± 17.98 years old) were included in this study. Two women dropped out; one because of an adverse event and the other as requested. Therefore, 27 patients completed the study. The total overactive bladder symptom and International Consultation on Incontinence Questionnaire-Short Form scores significantly decreased by 2.22 and 2.39 points, respectively (p < 0.01 each). In the frequency volume chart, the numbers of urgency episodes and leaks in 24 hours significantly decreased by 1.53 and 0.44, respectively (p = 0.02 each). Conclusions Transcutaneous tibial nerve stimulation therapy using Silver Spike Point® electrodes was useful for patients with refractory overactive bladder and, thus, has potential as a new treatment option for refractory overactive bladder.

Abstract
BACKGROUND Laparoscopic surgery (LS) is reported to reduce postoperative complications and hospital stay compared with open surgery (OP). Because patient selection may have been biased in previous studies, propensity score matching (PSM) analysis was used in this study to test the benefits of LS compared with OP. METHODS A total of 759 patients with stage I-III colorectal cancer undergoing curative surgery were retrospectively reviewed. To minimize confounding bias between LS and OP groups, a 1:1 PSM analysis was performed based on adjuvant chemotherapy, age, albumin, body mass index, American Society of Anesthesiologists physical status depth of tumor, gender, lymph node dissection, maximum tumor size, obstructive tumor, previous abdominal surgery, pathological stage, tumor differentiation, and tumor location. Statistical analyses including chi-square test, Mann-Whitney U test, univariate analyses and Kaplan-Meier method and log-rank test were performed using the data after PSM to investigate the benefits of LS compared with OP. RESULTS After PSM analysis, 460 patients remained in the study. The LS group had lower intraoperative blood loss (34 ± 70 vs 237 ± 391, mL; P < 0.001), lower frequency of postoperative small bowel obstruction (SBO) (17/213 vs 30/230; P = 0.045), lower rate of nasogastric tube insertion (7/223 vs 17/213; P = 0.036), and shorter postoperative hospital stay (13 ± 10 vs 25 ± 47, day; P < 0.001) than the OP group. Univariate analyses showed that LS significantly reduced the risk of postoperative SBO (odds ratio [OR] 0.532; 95% confidence interval [CI] 0.285-0.995; P = 0.048) and nasogastric tube insertion (OR 0.393; 95% CI 0.160-0.967; P = 0.042) compared with OP. There were no significant differences in OS and RFS between the groups. CONCLUSIONS LS reduced intraoperative blood loss, frequency of postoperative SBO, rate of nasogastric tube insertion, and postoperative hospital stay compared with OP.

Abstract
BACKGROUND The adipose stromal vascular fraction contains abundant mesenchymal stem cells and is utilized for cell therapy of male stress urinary incontinence. The purpose of this paper was to explore the effect of local transplantation of the stromal vascular fraction on improvement of damaged anal sphincter function. METHODS A rat model of vaginal distension was used as a model of damaged anal sphincter function. The adipose stromal vascular fraction was separated from the inguinal fat of syngeneic green fluorescent protein transgenic rats and delivered into the internal anal sphincter of vaginal distension rats. The maximum resting pressure was evaluated during insertion and withdrawal of the catheter at 4 or 10 days after vaginal distension treatment to estimate anal sphincter function. Green fluorescent protein-transfected human-adipose-derived mesenchymal stem cells were transplanted into the internal anal sphincter of nude rats. Hematoxylin-eosin and Masson trichrome staining were performed to evaluate tissue damage and collagen synthesis. Transplanted cells were identified using a green fluorescent protein antibody and a human-specific antibody. Activation of the transplanted human-ADSC was evaluated by quantitative RT-PCR RESULTS: The mean maximum resting pressure (during catheter withdrawal) of vaginal distension rats was significantly lower than that of control rats, and stromal vascular fraction injection normalized it 4 days after treatment (control: 5.66 ± 0.98, vaginal distension: 4.04 ± 1.28, vaginal distension + stromal vascular fraction: 5.92 ± 1.28 [mmHg, control versus vaginal distension: P = .039; vaginal distension versus vaginal distension + stromal vascular fraction: P = .007]). Histological examination showed that vaginal distension disrupted the internal anal sphincter, and the transplanted syngeneic stromal vascular fraction survived for 10 days. Transplanted xenogeneic human-adipose-derived mesenchymal stem cells survived in the internal anal sphincter of nude rats for 4 and 10 days. Genes related to extracellular remodeling were up-regulated in the transplanted human-adipose-derived mesenchymal stem cells CONCLUSION: Syngeneic and heterotopic transplanted adipose-derived mesenchymal stem cells engrafted in the internal anal sphincter and ameliorated damaged anal sphincter function in a rat model of vaginal distension.

Abstract
PURPOSE The pan-immune-inflammation value (PIV) is useful for stratifying outcomes in patients with metastatic colorectal cancer. However, it is unclear whether preoperative PIV can predict the surgical outcomes of patients with stage I-III colorectal cancer who receive surgery. METHODS The records of 758 patients with stage I-III colorectal cancer who received surgical treatment were retrospectively reviewed. The preoperative PIV was calculated as follows: (neutrophil count × platelet count × monocyte count)/lymphocyte count. The cut-off value was determined using a receiver operating characteristic curve for overall survival. RESULTS The cut-off value of the preoperative PIV was 376. Five hundred sixty-eight patients (74.9%) had low values (≤ 376), and 190 (25.1%) had high values (> 376). Univariate and multivariate analyses revealed that the PIV (> 376/ ≤ 376) (HR 2.485; 95% CI 1.552-3.981, P < 0.001) was significantly associated with overall survival, as well as age (> 60/ ≤ 60, years) (HR 1.988; 95% CI 1.038-3.807, P = 0.038), globulin-to-albumin ratio (> 0.83/ ≤ 0.83) (HR 2.013; 95% CI 1.231-3.290, P = 0.005) and postoperative complication (C-D grade III-V/0-II) (HR 1.991; 95% CI 1.154-3.438, P = 0.013). The Kaplan-Meier method and log-rank test showed significant differences in overall survival between patients with stage I-III disease with high (> 376) and low (≤ 376) PIVs. CONCLUSION The preoperative PIV is useful for predicting surgical outcomes in patients with stage I-III colorectal cancer.

Abstract
Telomerase reverse transcriptase (TERT) is reportedly expressed in various types of cancer. However, to the best of our knowledge, the significance of subcellular expression of TERT in hepatocellular carcinoma (HCC) has not been evaluated in detail. The present study evaluated TERT expression in resected HCC tumor tissues using immunohistochemistry. TERT expression was assessed in both the cytoplasm and the nucleus of HCC cells. The associations between TERT expression and clinical characteristics, including expression levels of DNA-dependent protein kinase catalytic unit (DNA-PKcs) and 8-hydroxyganosine (8-OHdG), were investigated. Among the 135 HCCs, TERT expression was positive only in the cytoplasm in 86 tumors (63.7%), was positive only in the nucleus in 3 tumors (2.2%), was positive in both the cytoplasm and the nucleus in 5 tumors (3.7%) and was negative in 41 tumors (30.4%). Similar results were confirmed using another antibody for TERT. Cytoplasmic TERT expression was markedly associated with hepatitis B surface antigen, poor tumor differentiation, and expression levels of DNA-PKcs and 8-OHdG. However, TERT expression in the cytoplasm or in the nucleus was not significantly associated with the overall or recurrence-free survival periods. In conclusion, TERT was mainly expressed in the cytoplasm of HCC tissues. Cytoplasmic TERT expression was closely associated with hepatitis B virus-related HCC and DNA-PKcs expression, as well as oxidative stress.

Abstract
Abstract
Background
Systemic sclerosis (SSc) is divided into two subtypes, diffuse and limited cutaneous SSc (dcSSc and lcSSc). The dcSSc subtype has more severe internal organ fibrosis than lcSSc. It is unclear whether cardiovascular magnetic resonance (CMR) parametric mapping can detect early cardiac involvement in these two subtypes.
Purpose
To detect cardiac involvement and evaluate differences between the two subtypes, we examined CMR parametric mapping.
Methods
57 consecutive SSc patients (27 dcSSc and 30 lcSSc) who visited our hospital from July 2018 to February 2021 and underwent CMR at 3.0T (Philips) were included. We analyzed myocardial damage using CMR parametric mapping and compared it with clinical data.
Results
Mean disease durations of dcSSc and lcSSc were 4.0±6.5 years and 4.4±8.3 years, respectively. Although there were no significant differences in LVEF (56.8±8.8 vs 59.6±7.2), the left and right atrial volume index were significantly larger in dcSSc compared with lcSSc (all p<0.05). Focal fibrosis as evaluated by late gadolinium enhancement was found in 9 SSc patients (15.7%) and 4 patients had pulmonary hypertension. DcSSc patients had significantly higher mid-ventricular native T1 (1350.8±73.2 vs 1312.9±52.1, p=0.029) and postcontrast T1 values (640.4±59.4 vs 604.6±42.5, p=0.015) as compared to lcSSc, although there were no significant differences in ECV and T2 values. Native T1 values in mid-ventricular septum were positively correlated with E/e' ratio of echocardiography in overall SSc patients and dcSSc patients but not in lcSSc patients (r=0.320, p=0.021; r=0.505, p=0.010; r=0.195, p=0.329). Native T1 values in mid-ventricular septum were also positively correlated with plasma levels of brain natriuretic peptide (BNP) in overall SSc patients and dcSSc patients but not in lcSSc patients (r=0.353, p=0.008; r=0.484, p=0.011; r=0.113, p=0.559).The multiple regression analysis considering age and sex revealed that mid-ventricular septum native T1 was the independent predictor of E/e' in SSc patients (β=0.306, p=0.026), and dcSSc patients (β=0.553, p=0.007) but not in lcSSc patients (β=−0.282, p=0.105). The ROC curve for predicting E/e'≥14, cut-off value of native T1 in mid-ventricular septum was ≥1348.5msec (AUC 0.762; 95% CI 0.571–0.953; sensitivity 80.0%; specificity 68.1%). BNP was significantly higher in patients with native T1≥1348.5 msec compared with native T1<1348.5 (102.8±112.8 vs 45.7±55.7; p=0.014). The interobserver variability of CMR parametric mapping values was excellent in this study.
Conclusion
DcSSc patients showed higher native T1 and larger left and right atrial volume index of CMR than lcSSc patients, suggesting that DcSSc patients had more severe myocardial involvement and left ventricular diastolic dysfunction than lcSSc patients. Early detection of the high native T1 may predict the occurrence of cardiovascular events in the future.

Abstract
BACKGROUND/AIM Computed tomography and positron emission tomography cannot detect all minute distant metastases and fully evaluate extensive vascular invasion in patients with pancreatic ductal adenocarcinoma (PDAC). The aim of this study was to investigate predictors of laparotomy only and palliative surgery in PDAC patients planning surgical resection. PATIENTS AND METHODS We reviewed 239 PDAC patients planning surgical resection. Patients were divided into two groups based on resection status. Multivariate analyses were performed to identify predictors of unresectable disease at laparotomy. RESULTS Twenty-five patients had unresectable disease at laparotomy. Multivariate analysis revealed that anatomical borderline resectable status (yes/no) (HR=5.458, p=0.012), pretreatment CA19-9 (>260/≤260 ng/ml) (HR=4.907, p=0.041), and tumor size (>25/≤25 mm) (HR=21.42, p=0.004) were associated with unresectable disease at laparotomy. CONCLUSION Borderline resectable status, pretreatment CA19-9, and tumor size were closely associated with unresectable disease at laparotomy in PDAC patients planning surgical resection.

Abstract
OBJECTIVE To compare the postoperative complications of intracorporeal anastomosis (ICA) and extracorporeal anastomosis (ECA) in patients undergoing laparoscopic right colectomy (LRC). BACKGROUND Although several studies have compared postoperative complications of ICA and ECA after LRC, most were retrospective studies. METHODS We performed a comprehensive electronic search of the literature to identify studies that compared postoperative complications between ICA and ECA in patients who underwent LRC. We performed meta-analysis using random-effects models to calculate the risk ratio (RR) and 95% confidence interval (CI) of experiencing complications, and we analyzed heterogeneity using I2 statistics. RESULTS Fifteen studies consist of randomized controlled trials, case-control studies, and propensity score matching studies involving a total of 3219 patients who underwent LRC were included. Among 1377 patients who received ICA, 255 (18.5%) had postoperative complications, whereas among 1652 patients who received ECA, 373 (22.6%) had such complications. The results of the meta-analysis revealed that ICA was associated with a significantly reduced risk of postoperative complications (RR, .73; 95% CI: .57-.95; P = .02; I2 = 57%) compared with ECA. Although there was no significant difference between the 2 groups in risk of anastomotic leakage (RR, .67; 95% CI: .39-1.17; P = .16; I2 = 8%), there was a significant difference between them in risk of surgical site infection (RR, .50; 95% CI: .34-.71; P = .0002; I2 = 0%). CONCLUSIONS Intracorporeal anastomosis is associated with a reduced risk of postoperative complications compared with ECA in patients undergoing LRC.

Abstract
OBJECTIVE To explore the influence of omentectomy on postoperative outcomes in patients with locally advanced gastric cancer (LAGC). BACKGROUND Although several meta-analyses have investigated the influence of bursectomy on postoperative outcomes in patients with LAGC, no meta-analyses have explored the influence of omentectomy on postoperative outcomes in such patients. METHODS We performed a comprehensive electronic search of the literature up to December 2020 to identify studies that compared postoperative outcomes between patients with LAGC who did and did not undergo omentectomy. A meta-analysis was performed using random-effects models to calculate the risk ratio (RR) and 95% confidence interval (CI), and heterogeneity was analyzed using I2 statistics. RESULTS Eight retrospective studies involving a total of 2658 patients with LAGC who underwent surgery were included in this meta-analysis. Among them, 3 propensity score matching (PSM) studies demonstrated that the 5-y recurrence-free survival (RFS) rate was 72.9% (314/431) in patients with LAGC who did not undergo omentectomy, whereas it was 70.3% (303/431) in those who did. The results revealed no significant difference in 5-y RFS between groups (RR, 0.91; 95% CI, 0.74-1.13; P = 0.41; I2 = 0%). Two PSM studies also revealed no significant difference in 5-y overall survival (OS) between groups (RR, 0.77; 95% CI, 0.52-1.13; P = 0.18; I2 = 47%). CONCLUSIONS The results of these meta-analyses show that omentectomy had no significant influence on 5-y OS, especially 5-y RFS, in patients with LAGC.

Abstract
OBJECTIVE To explore the impact of appendectomy history on emergence of Parkinson's disease (PD). BACKGROUND Although there are several studies to investigate the relationship between appendectomy history and emergence of PD, the results are still controversial. METHODS We performed a comprehensive electronic search of the literature (the Cochrane Library, PubMed, and the Web of Science) up to April 2020 to identify studies that had employed databases allowing comparison of emergence of PD between patients with and those without appendectomy history. To integrate the impact of appendectomy history on emergence of PD, a meta-analysis was performed using random-effects models to calculate the risk ratio (RR) and 95% confidence interval (CI) for the selected studies, and heterogeneity was analyzed using I2 statistics. RESULTS Four studies involving a total of 6 080 710 patients were included in this meta-analysis. Among 1 470 613 patients with appendectomy history, 1845 (.13%) had emergences of PD during the observation period, whereas among 4 610 097 patients without appendectomy history, 6743 (.15%) had emergences of PD during the observation period. These results revealed that patients with appendectomy history and without appendectomy had almost the same emergence of PD (RR, 1.02; 95% CI, .87-1.20; P = .83; I2 = 87%). CONCLUSION This meta-analysis has demonstrated that there was no significant difference in emergence of PD between patients with and those without appendectomy history.

Abstract
Abstract
Background
Beta blockers and angiotensin II receptor blockers take effect through G protein-coupled receptors (GPCRs) and their protective roles in heart failure are partially attributable to beta-arrestin biased agonism. CXCR7, a chemokine receptor, is beta-arrestin biased receptor and one of the most expressing GPCRs in the heart. CXCL12 is a common ligand of CXCR4 and CXCR7 and is known to ameliorate myocardial infarction (MI), reportedly through CXCR4 dependent mechanisms. However, the role of another receptor, CXCR7 and its downstream target including beta-arrestin is not fully elucidated in MI.
Purpose
The aim of this study is to uncover the role of CXCR7 in cardiomyocytes after MI.
Methods
First, we quantified CXCR7 mRNA expressions in neonate rat cardiomyocytes (NRCM) in a dish by qRT-PCR. NRCMs were treated with CXCR7 agonist: TC14012 and phosphorylation of extracellular signal regulated kinase (ERK) was measured as readout of the downstream of CXCR7, with immunoblotting. Second, MI was induced by left anterior descending artery (LAD) ligation in male 12-week-old mice. We explored spatial expressions of CXCR7 by qRT-PCR in infarct, peri-infarct and remote zones of wild-type MI mice. Finally, we developed cardiomyocyte-specific CXCR7 knockout mice (cKO) by the Cre/loxP system and analyzed CXCR7 expression in cKO by qRT-PCR. LAD ligation was also performed in cKO and littermate controls (Ctl). Heart weight (HW) was measured and systolic function was examined by echocardiography 4 weeks after ligation. Phosphorylated ERK was evaluated with immunoblotting one-day after ligation.
Results
First, we found that CXCR7 expression was significantly higher in NRCM than neonatal rat fibroblasts (NRFB) and ERK was phosphorylated by CXCR7 stimulation in NRCM. Second, CXCR7 expression was higher in infarct and peri-infarct zones than remote zones. Finally, cardiomyocyte-specific knockout of CXCR7 resulted in 78±21% reduction of CXCR7 expression in the whole heart. HW and left ventricular area was significantly greater (HW: Ctl 190.7±18.4, cKO 220.3±26.4 mg) and fractional area change of left ventricle was significantly lower in cKO than those in Ctl 4 weeks after MI (LV FAC: Ctl 20.6±4.9%, cKO 13.9±5.4%), indicating that loss of CXCR7 in cardiomyocytes caused left ventricle enlargement and systolic dysfunction. One day after MI of Ctl heart, ERK was more phosphorylated in peri-infarct zone than remote zone. However, this ERK phosphorylation in peri-infarct zone was reduced in cKO MI heart.
Conclusion
We revealed that CXCR7 is expressed in cardiomyocytes and deletion of this chemokine receptor in cardiomyocytes resulted in ventricle enlargement and systolic dysfunction possibly through ERK phosphorylation in peri-infarct zone. Therefore, CXCR7 in cardiomyocytes could prevent cardiac dysfunction after myocardial infarction, which may be another pathway of CXCL12 dependent-protective effect.

Abstract
BACKGROUND Recent retrospective subgroup analyses of patients with unresectable colon cancer (CC) receiving systemic chemotherapy have demonstrated that there is a significant difference in treatment outcome between patients with right-sided CC (RSCC) and those with left-sided CC (LSCC). However, it is impossible to divide patients with CC randomly into RSCC and LSCC groups before surgery. Therefore, the aim of this study is to explore the impact of primary tumor location (PTL) on survival after curative surgery for patients with CC using propensity score-matching (PSM) studies instead of randomization. MATERIALS AND METHODS We performed a comprehensive electronic search of the literature up to January 2019 to identify studies that had used databases allowing comparison of postoperative survival between patients with RSCC and those with LSCC. To integrate the impact of PTL on 5-year overall survival (OS) after curative surgery, a meta-analysis was performed using random-effects models to calculate the risk ratio (RR) and 95% confidence interval (CI) for the selected PSM studies. RESULTS Five studies involving a total of 398,687 patients with CC were included in this meta-analysis. Among 205,641 patients with RSCC, 69,091 (33.6%) died during the observation period, whereas among 193,046 patients with LSCC, 63,380 (32.8%) died during the same period. These results revealed that patients with RSCC and those with LSCC had almost the same 5-year OS (RR, 0.98; 95% CI, 0.89-1.07; p = .64; I2 = 97%). CONCLUSION This meta-analysis has demonstrated that there was no significant difference in 5-year OS between patients with RSCC and those with LSCC after curative resection. IMPLICATIONS FOR PRACTICE To integrate the impact of primary tumor location (PTL) on 5-year overall survival (OS) after curative surgery, five propensity score-matching (PSM) studies involving a total of 398,687 patients with colon cancer (CC) were included in this meta-analysis.

These results revealed that patients with RSCC and those with LSCC had almost the same 5-year OS (risk ratio, 0.98; 95% confidence interval, 0.89-1.07; p = .64; I2 = 97%).

Abstract
AIM The lymphocyte-to-monocyte ratio (LMR) is useful for predicting the prognosis of patients with gastric cancer (GC) and those with colorectal cancer (CRC) undergoing surgery. The relationship between the LMR and postoperative outcome of patients with early-stage gastrointestinal cancers such as stage I GC and CRC remains unclear. METHODS We retrospectively evaluated 323 stage I GC and 152 stage I CRC patients undergoing surgery. Univariate and multivariate analyses using the Cox proportional hazards model were performed to identify the clinical characteristics associated with overall survival (OS), and the cut-off values of these variables were determined by receiver operating characteristic analysis. The Kaplan-Meier method and log-rank test were used for postoperative survival comparisons according to the LMR (GC: LMR < 4.2 vs ≥4.2; CRC: LMR < 3.0 vs ≥3.0). RESULTS Univariate and multivariate analyses revealed that OS was significantly associated with the LMR (<4.2/≥4.2) (HR, 2.489; 95% CI, 1.317-4.702; P = 0.005), as well as age (>75/≤75 years) (HR, 3.511; 95% CI, 1.881-6.551; P < 0.001) and albumin level (≤3.5/>3.5 g/dL) (HR, 3.040; 95% CI, 1.575-5.869; P = 0.001), in stage I GC patients. Survival analysis demonstrated a significantly poorer OS in stage I GC patients with a LMR < 4.2 compared with ≥4.2 (P < 0.001). In stage I CRC patients, despite a significant difference in OS according to the LMR (<3.0 vs ≥3.0) (P = 0.040), univariate analysis revealed no significant association between the LMR and OS. CONCLUSION LMR is a useful predictor of the postoperative outcome of stage I GC patients treated surgically.

Abstract
Objective To examine the urodynamic effects of fesoterodine on neurogenic detrusor overactivity and/or low compliance bladder. Methods A total of 77 patients (52 men, 25 women; aged 61.6 ± 20.3 years) were given fesoterodine 4–8 mg/day and prospectively followed for 12 weeks. The primary end‐point variable was change in the maximum cystometric capacity on urodynamic study. The secondary end‐point was to assess the number of patients whose neurogenic detrusor overactivity disappeared, and the changes in the urodynamic parameters, lower urinary tract symptoms questionnaires and the 3‐day frequency volume chart parameters after the treatment. Results A total of 13 patients (16.9%) withdrew because of adverse events (dry mouth or blurred vision), and four patients dropped out for unknown reasons. Finally, 60 patients completed the study. Bladder capacity at first desire to void, maximum cystometric capacity and bladder compliance increased by 29.2 mL, 79.9 mL and 22.2 mL/cm H2O, respectively, showed statistical significance (P = 0.026, P < 0.001 and P < 0.001). Neurogenic detrusor overactivity disappeared in 12 of 51 patients (23.5%), and a significant increase was observed in bladder capacity at first involuntary contraction (P < 0.001), and a significant decrease was observed in maximum detrusor contraction (P < 0.001). In patients with low compliance bladder (with detrusor underactivity without neurogenic detrusor overactivity; n = 9), maximum cystometric capacity and bladder compliance increased significantly (P = 0.003 and P = 0.006, respectively). Overactive bladder symptom score, International Consultation on Incontinence Questionnaire–Short Form, most items of King’s Health Questionnaire, and the number of urgency episodes and leaks in a day decreased significantly after treatment. Conclusions Fesoterodine seems to be a valid treatment option for neurogenic detrusor overactivity and/or low compliance bladder in neurogenic bladder patients.

Abstract
New chemotherapeutic regimens such as S-1 plus docetaxel, S-1 plus oxaliplatin and capecitabine plus oxaliplatin are reported to be effective and safe as postoperative adjuvant chemotherapy (PAC) for advanced gastric cancer (GC) patients. Although the use of these PACs is increasing, it is still unclear how to choose the best regimen for advanced GC patients. Therefore, we aimed to investigate which clinical characteristics are associated with recurrence after curative surgery in patients receiving S-1 as PAC. Thirty-nine patients who received a PAC regimen with S-1 for more than 1 year after curative surgery for advanced GC were enrolled. Univariate and multivariate analyses using the Cox proportional hazard model were performed to detect clinical characteristics that correlated with recurrence. Patients were divided into two groups, recurrence, and non-recurrence, and receiver operating characteristic (ROC) curve analysis was used to identify the cut-off values. Kaplan-Meier analysis and the log-rank test were used for comparison of relapse-free survival (RFS). Fifteen patients had a recurrence after surgery (38.5%, 15/39). Multivariate analysis using clinical characteristics revealed that preoperative C-reactive protein (CRP) (>0.3/≤0.3, mg/dL) (HR 10.73;95% C.I., 1.824-63.14;P=0.009) was significantly associated with recurrence. Kaplan-Meier analysis and the log-rank test demonstrated that preoperative CRP (>0.3/≤0.3, mg/dL) was also significantly associated with RFS (P<0.001). Therefore, preoperative CRP is significantly associated with recurrence and RFS after curative surgery in advanced GC patients receiving S-1 as PAC.

Abstract
Abstract
Background/Introduction
In patients with atrial fibrillation (AF) undergoing percutaneous coronary intervention (PCI) with stent implantation, oral anticoagulation (OAC) plus dual antiplatelet therapy (DAPT) increases the risk of bleeding. The PRECISE-DAPT (P-DAPT) and DAPT scores were created to predict increased bleeding versus ischemic risk in patients undergoing DAPT. However, not much information is available on predicting bleeding risk associated with OAC concomitant with DAPT in patients with AF treated with coronary stents. Physical frailty or sarcopenia is considered an emerging predictor for bleeding in AF patients.
Purpose
To investigate the relationship between skeletal muscle mass and major bleeding risk in AF patients undergoing PCI and subsequent OAC and DAPT.
Methods
A total of 1,234 consecutive patients after PCI using newer-generation drug eluting stents were evaluated. An anti-thrombotic regimen without OAC was given to 1,077 patients, whereas OAC was required in 157 patients (12.7%) including AF (n = 96). The P-DAPT, DAPT, and HAS-BLED scores were calculated for each of the patients. Any out-of-hospital major bleeding events were identified based on BARC criteria during a median follow-up of 2.9 years. The fat-free mass index (FFMI; kg/m2) was calculated to evaluate skeletal muscle mass as follows: (7.38 + 0.02908 × urinary creatinine (mg/day)) / (height squared (m2)). A Cox proportional hazards model was used to test the significance of the FFMI and these risk scores as predictors of major bleeding, defined as BARC 3 or 5 events in AF patients. The receiver operating characteristic curve (ROC) analyses were used to examine the predictive ability of the FFMI and these scores to identify patients with major bleeding events.
Results
Major bleeding events were observed in 9 (9.3%) patients. Major bleeding was associated with a lower FFMI (hazard ratio [HR] 0.53; 95% confidence interval [CI] 0.36-0.79; p = 0.002), and higher P-DAPT score (HR, 1.07; 95% CI, 1.02-1.11; p = 0.003), but not with the DAPT (HR, 0.71; 95% CI, 0.45-1.12; p = 0.147) and the HAS-BLED score (HR, 1.00; 95% CI, 0.48-2.09; p = 0.990). In the non-OAC cohort, major bleeding was related to a higher P-DAPT score (HR, 1.05; 95% CI, 1.02-1.07; p < 0.0001), but the FFMI (HR, 0.89; 95% CI, 0.73-1.09; p = 0.265) and the DAPT score were not correlated. C-statistics for major bleeding events were 0.82 (95% CI, 0.71-0.93, p = 0.001) for the FFMI and 0.79 (95% CI, 0.68-0.90, p = 0.004) for the P-DAPT score.
Conclusions
Assessment of the FFMI for screening sarcopenia is useful to predict major bleedings specifically in patients with AF undergoing coronary stenting. Both the FFMI and P-DAPT could successfully predict major bleedings in AF patients after PCI. Whether novel bleeding risk scores combined with measuring body composition adequately identify high risk patients needs to be validated.

Abstract
DDT remains in use for malaria control in South Africa. We quantified DDTs in aquatic bird eggs from the highly biodiverse northern KwaZulu-Natal, a province of South Africa where DDT has been used for more than 80 years for malaria control. Pelican eggs had the highest ΣDDT concentration (7200 ng/g lipid mass; lm), Little Egret eggs had 6900 ΣDDT lm, African Openbill eggs had 3400 ng/g lm ΣDDT, and White-breasted Cormorant had 2400 ng/g lm. All species had non-significantly different mean concentrations of o,p'-DDT, p,p'-DDT, and ΣDDT, but with significant differences for p,p-DDE, o,p'-DDD, p,p'-DDD, %DDT, %DDD, and %lipid. The thinnest pelican eggshell (0.40 mm) had a ΣDDT concentration of 3300 ng/g lm.; the thickest shell (0.96 mm) had the lowest ΣDDT concentration at 29 ng/g lm; a 58% difference. Linear regressions of concentrations with shell thickness for the pelican eggs were significant for p,p'-DDE and p,p'-DDD, indicating risk of reproductive impairment. Compositional profiles indicate different food webs for the different species. DDT concentrations were lower than from another DDT-sprayed locality in South Africa, possible linked to differences in hydrology and rainfall. We conclude that significant ecotoxic threats associated with DDT remain in this area, and possibly threatens birds from less polluted areas. Our findings suggest continued negative human health and environmental impacts from DDT. There is an urgency to move away from DDT as quickly as possible; alternatively, to implement practices that prevent emissions of DDT to the environment while protecting human life.

Abstract
BACKGROUND AND AIM Although the Cancer of the Liver Italian Program (CLIP) score is useful for prognostication of patients with hepatocellular carcinoma (HCC), a previous study has reported that the CLIP score was unable to stratify the postoperative outcomes of HCC patients in whom the score was low (0-1). Recent studies have reported that the preoperative lymphocyte-to-monocyte ratio (LMR) is useful for prognostication of patients with various cancer. METHODS We reviewed 329 HCC patients with a low CLIP score (0-1) undergoing curative resection. This study had the approval of the Institutional Review Board (28068). Multivariate analyses were carried out to detect clinical factors correlating with overall survival (OS). Kaplan-Meier analysis and the log-rank test were used for comparison of OS. RESULTS Multivariate analysis showed that LMR (<4.35/≥4.35) was significantly associated with OS (hazard ratio [HR], 2.022; 95% CI, 1.141-3.583; P = 0.016) as well as portal vein invasion (HR, 2.410; 95%CI, 1.258-4.618; P = 0.008). Kaplan-Meier analysis and the log-rank test showed a significant difference in OS and relapse-free survival between patients with high LMR and those with low LMR. CONCLUSION Preoperative LMR is useful for stratifying the prognosis of HCC patients with a low CLIP score (0-1) undergoing curative resection.

Abstract
The use of 1,1'-(2,2,2-Trichloro-1,1-ethanediyl)bis(4-chlorobenzene) (DDT) as a pesticide for the control of insects vectors responsible for the spread of many life threatening diseases was officially banned in 1972 by the United States Environmental Protection Agency (USEPA). It was banned throughout the world, in most developed countries, because of the toxic effects it causes in wildlife, including birds and fish. However, DDT is still used in approximately 43 African countries, including South Africa, to control the spread of malaria. The lipophilic nature of DDT and therefore its persistence in the environment makes it extremely important for laboratory based studies to be conducted in an effort to evaluate the accumulation potential and possible physiological effects of DDT in aquatic organisms under controlled conditions. The aim of this study was to establish baseline bioaccumulation concentrations within Synodontis zambezensis following an acute exposure to 4,4'-DDT. The three metabolites analysed were 4,4'-DDE, 4,4'-DDD and 4,4'-DDT. None of the 2,4'-isomers were analysed in this study since the acute exposure used a solution of 98.7% pure 4,4'-DDT (Sigma-Aldrich PESTANAL®, Analytical Standard, CAS-No 50-29-3, Batch number SZBE057XV) and not a mixture of 4,4'-DDT and 2,4'-DDT as found in technical grade DDT. Soxhlet extraction of tissue samples and liquid/liquid extraction of water samples followed by analysis through Gas-chromatography mass-spectrophotometry was completed. Mean 4,4'-DDE, 4,4'-DDD and 4,4'-DDT concentrations ranged from 15.34 ng/g to 45.34 ng/g, 28.16 ng/g to 63.25 ng/g and 28.64 ng/g to 96.21 ng/g respectively. All of the accumulated concentrations fell within environmentally relevant concentrations with no input through the food web. The accumulated concentrations of 4,4'-DDT and its three metabolites resulted in oxidative stress responses within the gills and the liver tissue of S. zambezensis. Significant differences (p ≤ .05) were observed between malondialdehyde (MDA) and reduced glutathione (GSH) within the liver and in superoxide dismutase (SOD), catalase (CAT) and reduced glutathione (GSH) in the gills.

Abstract
Background Although an inferior vena cava (IVC) filter is used for preventing pulmonary thromboembolism (PTE) in patients with deep vein thrombosis, IVC filter penetration in the duodenum is a rare complication. Case presentation A 35-year-old man had previously undergone retroperitoneal lymph node dissection (RPLND) for testicular cancer and IVC filter placement for prevention of PTE. Esophagogastroduodenoscopy (EGD) for his epigastric pain revealed penetration of the IVC filter in the duodenum. The IVC filter was retrieved through cavotomy, and the duodenal penetration was repaired using EGD clipping. Although it was difficult to mobilize the duodenum due to adhesion resulting from RPLND, the use of a mesenteric approach enabled encircling of the IVC caudal to the duodenum. The mesenteric approach is useful and safe for taping the IVC caudal to the duodenum in cases where it is difficult to mobilize the duodenum. Conclusion IVC taping using the mesenteric approach allowed safe retrieval of the IVC filter after RPLND without postoperative complications.

Abstract
BACKGROUND Small bowel obstruction (SBO) is a well-known major postoperative complication requiring immediate diagnosis and treatment to avoid additional invasive surgical procedures. Water-soluble contrast medium is often given not only for diagnosis but also for treatment. Although numerous studies have investigated the significance of this treatment, no consensus has yet been established regarding its indications and efficacy. OBJECTIVE To explore whether Gastrografin can reduce the need for additional surgery in patients with postoperative SBO (PSBO). METHODS We carried out a comprehensive electronic search of the literature (Cochrane Library, MEDLINE, PubMed and the Web of Science) up to February 2017 to identify studies that had shown efficacy of Gastrografin in reducing the need for surgery in patients with PSBO. To integrate the individual effects of Gastrografin, a meta-analysis was done using random-effects models to calculate the risk ratio (RR) and 95% confidence interval (CI), and heterogeneity was analyzed using I 2 statistics. RESULTS Twelve studies involving a total of 1153 patients diagnosed as having PSBO were included in this meta-analysis. Not all patients received long-tube insertion. Among 580 patients who received Gastrografin, 100 (17.2%) underwent surgery, whereas among 573 patients who did not receive Gastrografin, 143 (25.0%) underwent surgery. Giving Gastrografin significantly reduced the need for surgery (RR, 0.66; 95% CI, 0.46-0.95; P = 0.02; I 2 = 52%) in comparison with patients who did not receive Gastrografin. CONCLUSION Results of this meta-analysis show that giving Gastrografin reduces the need for surgery in PSBO patients without long-tube insertion.

Abstract
PURPOSE Although alpha-fetoprotein (AFP) is a useful prognostic marker in patients with hepatocellular carcinoma (HCC), a recent study has shown that the preoperative neutrophil-to-lymphocyte ratio (NLR) is also associated with the postoperative survival in such patients. OBJECTIVE To investigate the significance of the NLR in patients with primary HCC (p-HCC) showing a normal preoperative AFP. METHODS Among 478 p-HCC patients undergoing curative surgery, 112 who had a normal AFP (< 8 ng/ml) were enrolled. The patients were divided into two groups: group A, who did not have an elevated NLR (≤ 3.2); and group B, who had an elevated NLR (> 3.2). Uni- and multivariate analyses were performed to compare clinical features with the overall survival (OS). RESULTS A multivariate analysis of the clinical features showed that the NLR (> 3.2/≤ 3.2) (hazard ratio 2.366; 95% CI 1.069-5.235; P = 0.034) was closely associated with the OS, along with the age (> 65/≤ 65 years) (P = 0.033). Group B had a significantly lower survival ratio than group A in terms of not only the OS (P = 0.013), but also the cancer-specific survival (P = 0.002) and relapse-free survival (P = 0.039). CONCLUSIONS An elevated NLR (> 3.2) is predictive of a poor survival in patients with primary HCC (p-HCC) showing normal AFP levels.

Abstract
Physical systems, such as currents and winds, have traditionally been considered responsible for transporting contaminants. Although evidence is mounting that animals play a role in this process through their movements, we still know little about how such contaminant biotransport occurs and the extent of effects at deposition sites. In the present study, we address this question by studying how rhinoceros auklets (Cerorhinca monocerata), a seabird that occurs in immense colonies (∼300 000 pairs at our study site, Teuri Island), affect contaminant levels at their colony and at nearby sites. More specifically, we hypothesize that contaminants are transported and deposited by seabirds at their colony and that these contaminants are passed on locally to the terrestrial ecosystem. To test this hypothesis, we analyzed the concentration of 9 heavy metal and metalloids, as well as δ13 C and δ15 N stable isotopes, in bird tissues, plants, and soil, both within and outside of the colony. The results show that rhinoceros auklets transport marine-derived mercury (Hg), possibly from their wintering location, and deposit Hg via their feces at their breeding site, thereby contaminating plants and soils within the breeding colony. The present study confirms not only that animals can transport contaminants from marine to terrestrial ecosystems, potentially over unexpectedly long distances, but also that bird tissues contribute locally to plant contamination.

Abstract
AIM To investigate the relationship between erythrocyte sedimentation rate (ESR) and postoperative survival of patients with colorectal cancer (CRC). MATERIALS AND METHODS Relationships between clinical characteristics and overall survival (OS) of patients with CRC were investigated using multivariate analysis. Receiver operating characteristics curve analysis was performed to decide the ideal cut-off values of clinical characteristics to divide patients into two groups, which were then compared using a survival curve analysis. RESULTS Three hundred and eleven patients with CRC undergoing surgery were enrolled. Multivariate analysis showed that ESR >40 mm/h (hazard ratio(HR)=2.601, 95% confidence interval(CI)=1.187-5.697; p=0.017) was associated with poorer OS, along with non-tubular pathology (p=0.034). Kaplan-Meier analysis revealed that patients with ESR >40 mm/h had poorer postoperative survival than those without ESR elevation (p<0.001). CONCLUSION Preoperative elevation of ESR (>40 mm/h) can predict poorer postoperative survival in patients with CRC.

Abstract
AIM A previous study has revealed that the albumin/globulin ratio (GAR) before treatment is a predictor of cancer-specific survival in patients with colorectal cancer (CRC). The aim of the present study was to investigate the clinical significance of GAR for prediction of postoperative survival in patients with CRC. METHODS Nine hundred and forty-one patients who had undergone elective CRC surgery were enrolled. Uni- and multivariate analysis models were performed to detect the clinical characteristics that were most closely associated with overall survival (OS). All recommended cutoff values were defined using receiver operating characteristic curve (ROC) analyses. Kaplan-Meier analysis was used to compare the OS curves between the high GAR (GAR > 0.83) and low GAR (GAR ≤ 0.83) groups. RESULTS Multivariate analysis using eight clinical characteristics selected by univariate analyses showed that the GAR was associated with OS (>0.83/≤0.83) (hazard ratio [HR], 1.979; 95% CI, 1.321-2.966; P = 0.001) along with carcinoembryonic antigen (CEA; >8.7/≤8.7, ng/mL; HR, 2.319; 95% CI, 1.569-3.428; P < 0.001), carbohydrate antigen 19-9 (CA19-9; >18.5/≤18.5, U/mL; HR, 1.727; 95% CI, 1.178-2.532; P = 0.005), and the neutrophil-to-lymphocyte ratio (NLR; >2.9/≤2.9; HR, 2.132; 95% CI, 1.454-3.126; P < 0.001), and the area under the ROC (AUROC) curve revealed that the GAR had the largest AUROC among these four clinical characteristics (GAR 0.711 > CEA 0.698 > CA19-9 0.676 > NLR 0.635). A significant difference in OS was observed between patients with low GAR and those with high GAR (P < 0.001). CONCLUSION Globulin-to-albumin ratio is a useful predictor of postoperative survival in patients with CRC.

Abstract
Photodynamic detection using 5-aminolevulinic acid has been used to identify the surgical margins during resection of human primary brain tumours. Although there are some reports on its use in malignant tumours in veterinary medicine, it has never been used for primary brain tumours. Here we describe a canine glioblastoma that was detected at autopsy with protoporphyrin IX fluorescence induced by orally administered 5-aminolevulinic acid. The fluorescence was strongest towards the centre of the lesion and was absent in normal brain tissue. Moreover, the fluorescence findings were consistent with MRI and histopathological findings. Our findings suggest that photodynamic detection using 5-aminolevulinic acid might be useful for intraoperative fluorescence-guided resection of malignant gliomas in dogs.

Abstract
The DNA-dependent protein kinase catalytic subunit (DNA-PKcs), which plays an important role in the DNA damage response, has been reported to be associated with tumor progression in various carcinomas. However, the clinical significance of DNA-PKcs in hepatocellular carcinoma (HCC) patients remains unclear. In the present study, we determined the tumor expression of DNA-PKcs in 104 resected HCC specimens by immunohistochemistry. The DNA-PKcs expression was scored as follows; 0, negative staining; 1, staining of nuclei at the tumor edge; 2, staining of the nuclei deep within the tumor and/or the tumor cytoplasm. The relationships between tumor expression of DNA-PKcs and the clinical characteristics and patient outcomes were investigated. Among the 104 HCCs, the distribution of staining for DNA-PKcs was as follows: 32 tumors were assigned a score of 0, 27 tumors were assigned a score of 1, and 45 tumors were assigned a score of 2. Statistical analyses revealed that tumor DNA-PKcs expression was significantly associated with the HBs antigen (HBsAg) status, presence/absence of portal vein invasion, size of the largest tumor nodule (<3.0 cm/>3.0, cm), and the serum alpha-fetoprotein level. Significant differences in the overall survival and recurrence-free survival were observed between patients showing (staining score 1 or 2) and not showing (staining score 0) tumor DNA-PKcs expression (P = 0.049 and P = 0.045, respectively). Our results suggest that tumor expression of DNA-PKcs is associated with tumor progression, HBsAg status and the postoperative outcomes in patients with HCC.

Abstract
AIM The globulin-to-albumin ratio (GAR) is useful for prognostication of patients with various cancers. However, the significance of GAR in gastric cancer (GC) remains unclear. Our purpose was to investigate the relationship between the GAR and outcome after curative resection in GC patients. METHODS Three-hundred and seventy-six patients who had undergone curative resection for GC were retrospectively reviewed. Univariate and multivariate analyses using the Cox proportional hazard model were performed to detect clinical characteristics that correlated with overall survival (OS), and their cut-off values were identified using receiver operating characteristic (ROC) curve analyses. Kaplan-Meier analysis and log-rank test were used for comparison of OS and relapse-free survival (RFS). RESULTS Multivariate analysis using 17 clinical characteristics selected by univariate analyses revealed that GAR (>0.80/≤0.80) was significantly associated with OS (hazard ratio [HR], 2.305; 95% CI, 1.122-4.735; P = 0.023), as well as lymph node metastasis (presence/absence) (HR, 2.417; 95% CI, 1.077-5.426; P = 0.032), neutrophil-to-lymphocyte ratio (>2.7/≤2.7) (HR, 2.368; 95% CI, 1.138-4.930; P = 0.002), and serosal invasion (presence/absence) (HR, 3.443; 95% CI, 1.048-11.31; P = 0.042). Kaplan-Meier analysis and log-rank test demonstrated that the OS and RFS of patients with a high GAR (>0.80) were significantly poorer than those with low GAR (≤0.80). CONCLUSIONS The GAR is a useful predictor of postoperative outcome among GC patients undergoing curative resection.

Abstract
Avian species have a unique renal structure and abundant blood flow into the kidneys. Although many birds die due to nephrotoxicity caused by chemicals, there are no early biomarkers for renal lesions. Uric acid level in blood, which is generally used as a renal biomarker, is altered when the kidney function is damaged by over 70%. Therefore, early biomarkers for kidney injury in birds are needed. In humans, glycomics has been at the forefront of biological and medical sciences, and glycans are used as biomarkers of diseases, such as carcinoma. In this study, a glycomics approach was used to screen for renal biomarkers in chicken. First, a chicken model of kidney damage was generated by injection of diclofenac or cisplatin, which cause acute interstitial nephritis (AIN) and acute tubular necrosis (ATN), respectively. The nephrotoxicity levels were determined by a blood chemical test and histopathological analysis. The plasma N-glycans were then analyzed to discover renal biomarkers in birds. Levels of 14 glycans increased between pre- and post administration in kidney-damaged chickens in the diclofenac group, and some of these glycans had the same presumptive composition as those in human renal carcinoma patients. Glycan levels did not change remarkably in the cisplatin group. It is possible that there are changes in glycan expression due to AIN, but they do not reflect ATN. Although further research is needed in other species of birds, glycans are potentially useful biomarkers for AIN in avian species.

Abstract
Background Although the use of laparoscopic resection for colon cancer (LRC) has been increasing, conversion to open surgery sometimes becomes necessary because of intraoperative difficulties. Although the Glasgow prognostic score (GPS) is well known to be a predictor of outcome in patients with various cancers, it is unclear whether the preoperative GPS can predict the need for conversion from laparoscopic to open surgery. Objective To investigate factors predictive of conversion from laparoscopic to open surgery in patients with colon cancer. Methods Data from 308 consecutive patients who underwent LRC between January 2006 and March 2017 were retrospectively enrolled. Preoperative clinical factors in patients who had undergone LRC were compared between conversion and non-conversion groups, and multivariate regression analysis was performed to identify preoperative factors that might predict conversion from laparoscopic to open surgery. Results Among 308 patients who had undergone LRC, conversion to open surgery was necessary in 28 (9.1%). Sixteen of the latter patients (6.8%) had GPS 0 (among a total of 234) and 6 (11.5%) had GPS 1 (among a total of 52). The proportion of patients with GPS 2 who required conversion was 27.2% (6/22), which was significantly higher than for those with GPS 0 or 1. Multivariate analysis demonstrated that GPS 2 (odds ratio [OR] 3.352; 95% confidence interval [CI] 1.049–10.71; p = 0.041) and preoperative ileus (OR 7.405; 95% CI 2.386–22.98; p = 0.001) were independent factors predictive of conversion from laparoscopic to open surgery. Conclusions A high preoperative GPS is an independent factor predictive of conversion from laparoscopic to open surgery in patients with colon cancer.

Abstract
Many countries with incidence of malaria, including those surrounding Maputo Bay, use dichloro-diphenyl-trichloroethane (DDT) to reduce mosquitoes. This study is the first to estimate the human health risk associated with consumption of marine fish from Maputo Bay contaminated with DDTs. The median for ∑DDTs was 3.8 ng/g ww (maximum 280.9 ng/g ww). The overall hazard ratio for samples was 1.5 at the 75th percentile concentration and 28.2 at the 95th percentile. These calculations show increased potential cancer risks due to contamination by DDTs, data which will help policy makers perform a risk-benefit analysis of DDT use in malaria control programs in the region.

Abstract
AIM Although it has been widely demonstrated that administration of Daikenchuto (DKT), a traditional Japanese herbal medicine, improves gastrointestinal (GI) motility in patients undergoing abdominal surgery, few studies have investigated the efficacy of perioperative DKT administration for relief of postoperative ileus (PI) in patients undergoing surgery for GI cancer. Therefore, the aim of this study was to investigate whether perioperative administration of DKT relieves PI in patients with GI cancer. PATIENTS AND METHODS We performed a comprehensive electronic search of the literature (Cochrane Library, PubMed, the Web of Science and ICHUSHI) up to December 2016 to identify studies that had shown the efficacy of perioperative DKT administration for relief of PI in patients with GI cancer. To integrate the individual effect of DKT, a meta-analysis was performed using random-effects models to calculate the risk ratio (RR) and 95% confidence interval (CI), and heterogeneity was analyzed using I2 statistics. RESULTS Seven studies involving a total of 1,134 patients who had undergone GI cancer surgery were included in this meta-analysis. Among 588 patients who received DKT perioperatively, 67 (11.4%) had PI, whereas among 546 patients who did not receive DKT perioperatively, 87 (15.9%) had PI. Perioperative administration of DKT significantly reduced the occurrence of PI (RR=0.58, 95% CI=0.35-0.97, p=0.04, I2=48%) in comparison to patients who did not receive DKT or received placebo. CONCLUSION The result of this meta-analysis suggests that perioperative administration of DKT relieves PI in patients undergoing surgery for GI cancer.

Abstract
BACKGROUND AND OBJECTIVES Although the globulin-to-albumin ratio (GAR) is useful for prognostication of patients with various cancers, its relationship with hepatocellular carcinoma (HCC) remains unclear. The study aims to investigate the relationship between GAR and postoperative survival among patients with HCC undergoing potentially curative liver resection (LR). METHODS We retrospectively reviewed 368 patients with newly diagnosed HCC who underwent initial and potentially curative LR. Univariate and multivariate analyses using the Cox proportional hazard model were performed to detect clinical characteristics that correlated with overall survival (OS). Kaplan-Meier analysis and log-rank test were used to compare OS and disease-free survival (DFS). RESULTS The result of multivariate analysis using 25 clinical characteristics selected by univariate analysis revealed that the GAR (≥0.918/<0.918) was significantly associated with OS (hazard ratio [HR], 2.398; 95% confidence interval [CI], 1.012-5.683; P = 0.047), as well as platelet count (<14/≥14, ×104 /mm3 ) and portal vein invasion (presence/absence). Kaplan-Meier analysis and log-rank test demonstrated that the OS and DFS of patients with a high GAR (>0.918) were significantly worse than that of patients with a low GAR (≤0.918). CONCLUSIONS The GAR is a useful predictor of postoperative survival among patients with HCC undergoing potentially curative LR.

Abstract
It is well known that intersigmoid hernia (ISH) is a rare condition. Here we describe our experience of laparoscopic surgery for small-bowel obstruction (SBO) due to ISH after sufficient decompression involving long-tube insertion.A 45-year-old woman with no history of abdominal surgery visited our hospital with epigastric pain. She was diagnosed as having SBO and underwent long-tube insertion as conservative therapy. However, her symptoms did not improve. Gastrografin contrast enema via the long-tube demonstrated a beak sign in the lower left abdomen and CT showed incarcerated small bowel was successively covered by sigmoid mesocolon, suggesting that the SBO was due to ISH, and she underwent laparoscopic surgery after sufficient decompression of the dilated small bowel.Intraoperative examination demonstrated incarceration of a loop of the small bowel in the intersigmoid fossa without strangulation. Because the incarcerated portion of the small bowel was not necrotized, herniation repair was performed by removing the incarcerated small bowel from the intersigmoid fossa without closure of the hernia orifice.The postoperative course was uneventful, and the patient is now free of symptoms and recurrence 12 months after surgery. Laparoscopic surgery after sufficient decompression is a useful treatment for SBO due to ISH.
