Abstract
CONTEXT In acute glufosinate poisoning, sudden respiratory arrest and convulsion can occur after a latent period of 4-60 h. There is still no factor that accurately predicts the occurrence of these symptoms. OBJECTIVE To elucidate the predictors of severe effects following acute glufosinate poisoning. MATERIALS AND METHODS This study is a retrospective observational case series. The subjects were 16 patients who had acute glufosinate poisoning. They were divided into a group with respiratory arrest or convulsion during hospitalization (severe group) and a group without (non-severe group). The following characteristics (or predictors) were compared between the groups: age, sex, calculated amount of glufosinate (volume of ingested poison (glufosinate-containing herbicide) × glufosinate concentration of the product), time duration from poison ingestion to arrival at our hospital, use of gastric lavage, use of whole bowel irrigation, Glasgow Coma Scale, laboratory parameters, PaO₂/FiO₂ ratio (P/F ratio), shock index, and presence or absence of systemic inflammatory response syndrome (SIRS) on arrival. RESULTS The P/F ratio was significantly lower in the severe group than in the non-severe group (median, 287.5 vs. 409.0; P = 0.049). The receiver operating characteristic (ROC) curve was plotted for the predictor of increasing severity based on the P/F ratio. The area under the curve was 0.714, and the optimal cutoff point for increasing severity was 374.0. The sensitivity was 75.0%, specificity of 71.4%, and accuracy of 75.0%. The shock index was significantly higher (median, 0.52 vs. 0.41; P = 0.031). Significantly more patients had SIRS in the severe group than in the non-severe group (P = 0.015). Logistic regression analysis was performed with a backward elimination procedure. SIRS was selected as the independent predictor of increasing severity (odds ratio, 29.810; 95% confidence interval, 1.011-878.952; P = 0.049). DISCUSSION AND CONCLUSION Severe effects following acute glufosinate poisoning were associated with two positive SIRS criteria. A low P/F ratio may be useful for predicting the occurrence of respiratory complications.

Abstract
OBJECTIVES We compared intravascular ultrasound (IVUS) and 2 different generations of optical coherence tomography (OCT)-time-domain OCT (TD-OCT) and frequency-domain OCT (FD-OCT)-for the assessment of coronary disease and percutaneous coronary intervention (PCI) using stents. BACKGROUND OCT is a promising light-based intravascular imaging modality with higher resolution than IVUS. However, the paucity of data on OCT image quantification has limited its application in clinical practice. METHODS A total of 227 matched OCT and IVUS pull backs were studied. One hundred FD-OCT and IVUS pull backs in nonstented (n = 56) and stented (n = 44) vessels were compared. Additionally, 127 matched TD-OCT and IVUS images were compared in stented vessels. RESULTS FD-OCT depicted more severe native coronary disease than IVUS; minimal lumen area (MLA) was 2.33 ± 1.56 mm(2) versus 3.32 ± 1.92 mm(2), respectively (p < 0.001). Reference vessel dimensions were equivalent between FD-OCT and IVUS in both native and stented coronaries, but TD-OCT detected smaller reference lumen size compared with IVUS. Immediately post-PCI, in-stent MLAs were similar between FD-OCT and IVUS, but at follow-up, both FD-OCT and TD-OCT detected smaller MLAs than did IVUS, likely due to better detection of neointimal hyperplasia (NIH). Post-PCI malapposition and tissue prolapse were more frequently identified by FD-OCT. CONCLUSIONS FD-OCT generates similar reference lumen dimensions but higher degrees of disease severity and NIH, as well as better detection of malapposition and tissue prolapse compared with IVUS. First-generation TD-OCT was associated with smaller reference vessel dimensions compared with IVUS.

Abstract
AIM The annual incidence of colonic diverticular bleeding is increasing, but treatments are not yet well established. Here we aimed to identify the risk factors for early re-bleeding and to determine the associated duration of hospitalization. METHOD Records of 90 emergent patients with colonic diverticular bleeding between 1999 and May 2012 were retrospectively reviewed. They were divided into an early re-bleeding within 1 month group (n = 24) and a no re-bleeding group (n = 66) and we investigated the risk factors for early re-bleeding. In the former group, we calculated the time from the first haemostasis to early re-bleeding and the associated duration of hospitalization. RESULTS Univariate analysis showed that there were significantly more patients with signs of shock (P = 0.00055) and active bleeding on the first colonoscopy after admission (P = 0.020) in the early re-bleeding group. Multivariate conditional logistic regression analysis using stepwise variable selection showed that signs of shock on admission (odds ratio, 5.23; 95% confidence interval, 1.84-14.90; P = 0.0019) remained statistically significant. All patients who re-bled without signs of shock (n = 7) and 16 of 17 with signs of shock re-bled within 126 h (5.25 days) of initial hospitalization. CONCLUSION Shock was an independent risk factor for early re-bleeding. The associated duration of hospitalization was 6 days.

Abstract
BACKGROUND Coronary artery calcification (CAC) presents unique challenges for percutaneous coronary intervention. Calcium appears as a signal-poor region with well-defined borders by frequency-domain optical coherence tomography (FD-OCT). The objective of this study was to demonstrate the accuracy of intravascular FD-OCT to determine the distribution of CAC. METHODS AND RESULTS Cadaveric coronary arteries were imaged using FD-OCT at 100-μm frame interval. Arteries were subsequently frozen, sectioned and imaged at 20-μm intervals using the Case Cryo-Imaging automated system(TM). Full volumetric co-registration between FD-OCT and cryo-imaging was performed. Calcium area, calcium-lumen distance (depth) and calcium angle were traced on every cross-section; volumetric quantification was performed offline. In total, 30 left anterior descending arteries were imaged: 13 vessels had a total of 55 plaques with calcification by cryo-imaging; FD-OCT identified 47 (85%) of these plaques. A total of 1,285 cryo-images were analyzed and compared with corresponding co-registered 257 FD-OCT images. Calcium distribution, represented by the mean depth and the mean calcium angle, was similar, with excellent correlation between FD-OCT and cryo-imaging respectively (mean depth: 0.25±0.09 vs. 0.26±0.12mm, P=0.742; R=0.90), (mean angle: 35.33±21.86° vs. 39.68±26.61°, P=0.207; R=0.90). Calcium volume was underestimated in large calcifications (3.11±2.14 vs. 4.58±3.39mm(3), P=0.001) in OCT vs. cryo respectively. CONCLUSIONS Intravascular FD-OCT can accurately characterize CAC distribution. OCT can quantify absolute calcium volume, but may underestimate calcium burden in large plaques with poorly defined abluminal borders.

Abstract
Background—
The presence of chronic total occlusion of the right coronary artery (CTO-RCA) in patients undergoing percutaneous interventions for unprotected left main (ULM) disease may affect the prognosis. In this study, we evaluated the immediate results and follow-up of patients with ULM-percutaneous interventions and with or without associated CTO-RCA.
Methods and Results—
Between March 2002 and December 2008, a total of 568 consecutive patients with ULM stenosis treated with drug-eluting stent were included in this analysis. The mean EuroScore and SYNTAX scores were 4.05±2.62 and 28.12±10.82, respectively. Of these, 522 had ULM lesions without residual CTO-RCA (493 ULM without CTO-RCA+29 ULM with treated CTO-RCA), and 46 patients had residual CTO-RCA. At 1466 days (interquartile range, 1150–1917) follow-up, the cardiac-death occurred in 41 patients (7.2%). Cardiac-death was more frequently observed in patients with ULM and residual CTO-RCA as compared with those without residual CTO-RCA (adjusted hazard ratios, 2.163 [95% confidence interval, 1.018–4.597];
P
=0.045). However, target lesion revascularization occurred less frequently in patients with residual CTO-RCA (adjusted hazard ratios, 0.321 [95% confidence interval, 0.13–0.794];
P
=0.014), resulting in the similar major adverse cardiovascular events rates between the 2 groups. When we analyzed patients with concomitant ULM and CTO-RCA, cardiac-death was significantly higher in patients with residual as compared with treated CTO-RCA (log-rank
P
=0.01) despite no difference in baseline characteristics.
Conclusions—
Cardiac-death occurred more frequently in patients with residual CTO-RCA as compared with those without residual CTO-RCA. These findings suggest that recanalization of CTO-RCA has significant impact on the long-term cardiac-mortality in patients undergoing ULM-percutaneous interventions probably by offering reserve coronary circulation, if in-stent restenosis were to occur in the treated left main.

Abstract
BACKGROUND Although immunoglobulin A (IgA) plays a key role in regulating gut homeostasis, its role in canine inflammatory bowel disease (IBD) is unknown. HYPOTHESIS IgA expression may be altered in dogs with IBD, unlike that observed in healthy dogs and dogs with other gastrointestinal diseases. ANIMALS Thirty-seven dogs with IBD, 10 dogs with intestinal lymphoma, and 20 healthy dogs. METHODS Prospective study. IgA and IgG concentrations in serum, feces, and duodenal samples were measured by ELISA. IgA(+) cells in duodenal lamina propria and IgA(+) CD21(+) peripheral blood mononuclear cells (PBMCs) were examined by immunohistochemistry and flow cytometry, respectively. Duodenal expression of the IgA-inducing cytokine transforming growth factor β (TGF-β), B cell activating factor (BAFF), and a proliferation-inducing ligand (APRIL) was quantified by real-time RT-PCR. RESULTS Compared to healthy dogs, dogs with IBD had significantly decreased concentrations of IgA in fecal and duodenal samples. The number of IgA(+) CD21(+) PBMCs and IgA(+) cells in duodenal lamina propria was significantly lower in dogs with IBD than in healthy dogs or dogs with intestinal lymphoma. Duodenal BAFF and APRIL mRNA expression was significantly higher in IBD dogs than in the healthy controls. Duodenal TGF-β mRNA expression was significantly lower in dogs with IBD than in healthy dogs and dogs with intestinal lymphoma. CONCLUSIONS AND CLINICAL IMPORTANCE IBD dogs have decreased IgA concentrations in feces and duodenum and fewer IgA(+) PBMCs, which might contribute to development of chronic enteritis in dogs with IBD.

Abstract
BACKGROUND Novel vascular scaffolds aim at equipoise between safety and efficacy. Intravascular optical coherence tomography (OCT) allows in-vivo serial assessment of stent-vessel interactions with high resolution and frequent sampling and may complement histology assessment. We investigated the vascular response to a novel absorbable coating sirolimus-eluting stent (AC-SES) by means of serial OCT and histology evaluation in a porcine model. METHODS One AC-SES and one bare-metal stent (BMS) were implanted in separate coronary arteries of three Yucatan mini-swine. Serial OCT was performed post procedure and at 3-, 28-, 90-, and 180-day follow-up. Normalized optical density (NOD) was used for the assessment of tissue response over time. Histological evaluation was performed at day 180. RESULTS A total of 6408 stent struts were analyzed. OCT revealed 100% of struts covered at 28 days, and a significant difference in NOD from 3 to 28 days (0.64 ± 0.07 vs 0.71 ± 0.05, respectively; P<.001) in the AC-SES group. Neointimal thickness was 0.14 ± 0.08 mm, 0.17 ± 0.11 mm, and 0.16 ± 0.09 mm in the AC-SES group and 0.18 ± 0.10 mm, 0.14 ± 0.09 mm, and 0.10 ± 0.08 mm in the BMS group, while rates of uncovered struts were 0%, 0%, and 3.1% and 1.4%, 7.8%, and 21.5%, respectively, at 28, 90, and 180 days. Minimal inflammation and a mature endothelialization were demonstrated in both groups by histology. CONCLUSION OCT serial assessment of vascular response suggested NIH maturation 28 days following AC-SES implantation in pigs. These findings, coupled with histological demonstration of low inflammation scores and complete endothelial coverage as measured at 180 days, suggest a satisfactory healing response to AC-SES.

Abstract
X-chromosome inactivation pattern (XCIP) analysis has been widely used to assess cell clonality in various types of neoplasms in humans. In the present study, a polymerase chain reaction–based feline XCIP analysis using the feline androgen receptor gene was developed. To construct the system of the analysis, polymorphism in CAG tandem repeats within the feline androgen receptor gene was explored using somatic DNAs from 50 male and 103 female cats. CAG tandem repeats in exon 1 of the feline androgen receptor gene were found to be polymorphic, containing 15 to 22 CAG repeats. Of the 103 female cats, 70 (68%) were heterozygous for the number of CAG repeats, indicating the possible usefulness of XCIP analysis in cats. Application of the feline XCIP analysis to 3 feline mammary gland adenocarcinoma cell lines revealed distinctly skewed XCIPs in these cell lines, indicating their clonal origins. Twelve (80%) of the 15 primary tissue/cell samples obtained from cats with various neoplastic diseases showed skewed XCIPs. Moreover, bone marrow samples from 3 cats with myelodysplastic syndrome were also found to have skewed XCIPs. The polymerase chain reaction–based XCIP analysis developed in this study can provide information on cell clonality in female cats, potentially facilitating the differential diagnosis of various disorders in cats.
