Abstract
BACKGROUND Menopausal symptoms are common among middle-aged women. Working women with severe menopausal symptoms are more likely to experience presenteeism-a condition where employees continue to work despite feeling unwell. However, it remains unclear as to which specific symptoms women experience during the menopausal transition and postmenopausal periods that primarily contribute to presenteeism. AIMS To evaluate the associations between types of menopausal symptoms and presenteeism among Japanese women. METHODS A cross-sectional study of 4000 women aged 40-59 years who were currently working was conducted in Japan in September 2022. We used an online self-administered questionnaire that included items on demographic characteristics, the Menopause Rating Scale for measuring menopausal symptoms and the Work Functioning Impairment Scale for measuring presenteeism. Logistic regression analysis was performed. RESULTS Women with severe overall menopausal symptoms had 12.18-fold (95% confidence interval [CI] 9.09-16.33, P < 0.001) increased odds of presenteeism compared with those without symptoms. Participants with psychological symptoms also had significantly higher presenteeism (severe: odds ratio: 9.18, 95% CI 6.60-12.78, P < 0.001). However, after controlling for psychological symptoms, there were no significant associations between somatic and urogenital symptoms and presenteeism. CONCLUSIONS The results indicate that menopausal symptoms, especially psychological symptoms, have a significant impact on presenteeism among Japanese women. Organizations need to address menopausal symptoms in the workplace, with an emphasis on reducing work-related stress for women with menopausal symptoms.

Abstract
BACKGROUND Two major definitions exist for presenteeism: sickness presenteeism and impaired work function. The evidence for comparing previous studies on presenteeism is insufficient because of the different definitions of presenteeism used. AIMS To assess the relationship between the two major definitions of presenteeism. METHODS This cross-sectional study analysed secondary data on 5334 respondents to an employee survey administered in a construction company in Japan. Impaired work function was measured using the Work Functioning Impairment Scale (WFun). Multiple logistic regression was performed. RESULTS A strong linear association was observed between the number of days of sickness presenteeism and impaired work function (all P < 0.001). In contrast, the number of days of sickness absence was only partially positively associated with impaired work function. All choices for most frequent health problem were positively associated with impaired work function, beginning with mental problems (adjusted odds ratio [OR] = 20.45, 95% confidence interval [CI]: 14.94-28.01), followed by malaise (adjusted OR = 11.91, 95% CI: 9.08-15.62) and sleeping problems (adjusted OR = 8.62, 95% CI: 6.57-11.33). CONCLUSIONS A strong relationship was observed between the two major definitions of presenteeism, even after adjusting for a variety of chronic health conditions. Although a consensus on the definition of presenteeism is yet to be reached, this study provides insight on comparing existing studies on presenteeism.

Abstract
BACKGROUND Presenteeism is an important factor in workers' health. However, few studies have examined how variables such as socio-economic status, health status, workplace status and health literacy correlate with and affect presenteeism. AIMS To assess the correlates of presenteeism with a focus on health-related factors, work-related factors and health literacy. METHODS We conducted a cross-sectional study of 2914 Japanese workers from one company. We used a self-administered questionnaire to assess socio-demographic characteristics, health status, work environment, presenteeism and health literacy. RESULTS Forty-one per cent of participants were under 40 years of age and 70% were male. We found that 59% of the participants were at high risk of presenteeism. Presenteeism was associated with sex, age, household income, marital status, health-related factors (i.e. self-rated health status, dietary choices, exercise habits), work-related factors (i.e. workplace support, job demands, job control) and health literacy. Logistic regression analyses indicated that presenteeism was associated with self-rated health status, overtime hours, workplace support, job demands, job control and health literacy after adjusting for sex, age and income. CONCLUSIONS Health-related factors, work-related factors and health literacy are all associated with presenteeism. Improving the workplace environment, especially factors such as overtime working hours, workplace support, job demands and job control, and increasing health literacy may reduce presenteeism among general office workers.

Abstract
BACKGROUND Paramedics need to be in good physical health to be able to respond to emergencies. We hypothesized that near misses by paramedics and unanticipated incidents that cause no harm may be associated with presenteeism during emergency rescues. AIMS To examine the association between presenteeism and near misses among paramedics. METHODS A cross-sectional study was conducted among 254 paramedics using a self-administered questionnaire. Presenteeism was measured using the work functioning impairment scale (WFun). RESULTS Twelve per cent of respondents experienced high work function impairment indicating presenteeism. The rate of near-miss experiences steadily increased with increasing work function impairment among paramedics (WFun score category: middle, odds ratio (OR) 3.62, 95% confidence interval (CI) 1.62-8.11; high, OR 4.36, 95% CI 1.37-13.84; very high, OR 8.62, 95% CI 2.09-35.48). CONCLUSIONS This study demonstrated a positive relationship between impaired work function indicating presenteeism and near misses among paramedics. This suggests that presenteeism may be associated with errors that have the potential to cause serious accidents. Improved access to treatment for frequent health problems may reduce the number of incidents among paramedics.

Abstract
BACKGROUND AND PURPOSE Contrast-enhanced FIESTA can depict anterior optic pathways in patients with large suprasellar tumors. We assessed whether the degree of kink in the optic nerve at the optic canal orifice on contrast-enhanced FIESTA correlates with the postoperative improvement of visual impairment in patients with pituitary macroadenoma. MATERIALS AND METHODS Thirty-one patients with pituitary macroadenoma who underwent preoperative MR imaging and an operation were evaluated. We measured the optic nerve kinking angle on sagittal oblique contrast-enhanced FIESTA parallel to the optic nerve; the optic nerve kinking angle was defined as the angle between a line parallel to the planum sphenoidale and a line parallel to the intracranial optic nerve at the optic canal orifice. We used logistic regression analyses to determine whether the clinical (sex, age, and duration of symptoms) and imaging (tumor height, chiasmal compression severity, hyperintense optic nerve on T2WI, and optic nerve kinking angle) characteristics were associated with the postoperative improvement (good-versus-little improvement) of visual acuity disturbance and visual field defect. RESULTS There were 53 impaired sides before the operation: 2 sides with visual acuity disturbance alone, 25 with visual field defect alone, and 26 with both. After the operation, good improvement was found in 17 of the 28 sides with visual acuity disturbance and in 32 of the 51 sides with visual field defects. Only the optic nerve kinking angle was significantly associated with good improvement of the visual acuity disturbance (P = .011) and visual field defect (P = .002). CONCLUSIONS The degree of the optic nerve kinking angle was an independent predictor of postoperative improvement, indicating that irreversible damage to the optic nerve may be associated with its kinking at the optic canal orifice.

Abstract
Background Adjunctive thrombus aspiration (TA) during primary percutaneous coronary intervention (PCI) was reported to promote better coronary and myocardial reperfusion. However, long-term mortality benefit of TA remains controversial. The objective of this study is to investigate the clinical impact of TA on long-term clinical outcomes in patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary PCI. Methods and Results The CREDO-Kyoto AMI Registry is a large-scale cohort study of acute myocardial infarction patients undergoing coronary revascularization in 2005–2007 at 26 hospitals in Japan. Among 5429 patients enrolled in the registry, the current study population consisted of 3536 patients who arrived at the hospital within 12 hours after the symptom onset and underwent primary PCI. Clinical outcomes were compared between the 2 patient groups with or without TA. During primary PCI procedures, 2239 out of 3536 (63%) patients underwent TA (TA group). The cumulative 5-year incidence of all-cause death was significantly lower in the TA group than in the non-TA group (18.5% versus 23.9%, log-rank P<0.001). After adjusting for confounders, however, the risk for all-cause death in the TA group was not significantly lower than that in the non-TA group (hazard ratio: 0.90, 95% CI: 0.76 to 1.06, P=0.21). The adjusted risks for cardiac death, myocardial infarction, stroke, and target-lesion revascularization were also not significantly different between the 2 groups. Conclusions Adjunctive TA during primary PCI was not associated with better 5-year mortality in STEMI patients.

Abstract
In this study, plasma MMP-9 activity was evaluated in cats with lymphoma. Plasma samples were obtained from 26 cats with lymphoma before treatment. From 13 of the included 26 cats, plasma samples were obtained 4 weeks after the initiation of treatment. Plasma samples were also obtained from 10 healthy cats as a control. Plasma MMP-9 activity was examined by gelatin zymography and semi-quantitative value (arbitrary unit; a.u.) for each sample was calculated. Relatively high levels of MMP-9 were observed in cats with lymphoma compared with those in healthy control cats. MMP-9 quantification through zymography showed significantly higher activity in cats with lymphoma (median, 0.63 a.u.; range, 0.23-3.24 a.u.) than in healthy controls (0.22 a.u.; 0.12-0.46 a.u.; P < 0.01). MMP-9 activities were significantly different before (0.73 a.u.; 0.30-3.24 a.u.) and after treatment (0.50 a.u.; 0.14-1.32 a.u.; P = 0.017). Measuring plasma MMP-9 activity in cats with lymphoma may become an appropriate monitoring tool for feline lymphoma.

Abstract
X-chromosome inactivation pattern (XCIP) analysis has been widely used to assess cell clonality in various types of human neoplasms. In this study, a polymerase chain reaction–based canine XCIP analysis of the androgen receptor ( AR) gene was applied for the assessment of cell clonality in canine hematopoietic tumors. This XCIP analysis is based on the polymorphic CAG repeats in the AR gene and the difference of methylation status between active and inactive X chromosomes. We first examined the polymorphisms of 2 CAG tandem repeats in the AR gene in 52 male and 150 female dogs of various breeds. The 2 polymorphic CAG repeats contained 9 to 12 and 10 to 14 CAGs in the first and second CAG repeats, respectively. Of the 150 female dogs, 74 (49.3%) were heterozygous for the first and/or second polymorphic CAG tandem repeats, indicating the utility of XCIP analysis in these dogs. Canine XCIP analysis was then applied to clinical samples from female dogs with canine high-grade lymphoma, chronic myelogenous leukemia, acute myelogenous leukemia, and benign lymph node hyperplasia. Of 10 lymphoma cell samples, 9 (90%) showed skewed XCIPs, indicating their clonal origins, whereas all the nonneoplastic lymph node samples showed balanced XCIPs. Moreover, bone marrow specimen from a dog with acute myelogenous leukemia and peripheral leukocyte specimens from 2 dogs with chronic myelogenous leukemia showed skewed XCIPs. XCIP analysis was successfully employed to demonstrate the cell clonality of canine hematopoietic tumors in this study and will be applicable to evaluate the clonality in various proliferative disorders in dogs.

Abstract
The diagnosis of gall bladder mucoceles (GM) in dogs has become increasingly frequent in veterinary medicine. Primary breed-specific hyperlipidaemia is reported in Shetland Sheepdogs and Miniature Schnauzers, breeds in which GM are known to occur more frequently than in other breeds. The objective of this study was to evaluate the association between GM and hyperlipidaemia in dogs. The study design was a retrospective case control study. Medical records of dogs diagnosed with GM at the Veterinary Medical Centre of The University of Tokyo between 1 April 2007 and 31 March 2012, were reviewed. Fifty-eight dogs with GM and a record of either serum cholesterol, triglyceride, or glucose concentrations were included in the study. Hypercholesterolaemia (15/37 cases; odds ratio [OR]: 2.92; 95% confidence interval [CI]: 1.02-8.36) and hypertriglyceridaemia (13/24 cases; OR: 3.55; 95% CI:1.12-15.91) showed significant association with GM. Pomeranians (OR: 10.69), American Cocker Spaniels (OR: 8.94), Shetland Sheepdogs (OR: 6.21), Miniature Schnauzers (OR: 5.23), and Chihuahuas (OR: 3.06) were significantly predisposed to GM. Thirty-nine out of 58 cases had at least one concurrent disease, including pancreatitis (five cases), hyperadrenocorticism (two cases), and hypothyroidism (two cases). A significant association between GM and hyperlipidaemia was confirmed, suggesting that hyperlipidaemia may play a role in the pathogenesis of GM.

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
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 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
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.

Abstract
Molecular regulation of fibrosis in chronic canine hepatitis is poorly understood. The authors employed quantitative polymerase chain reaction (PCR) to determine the expression levels of genes reported to be related to fibrosis in other species (human, mouse, and rat) and to elucidate the relationship of these genes with the degree of fibrosis and the presence or absence of ascites and/or jaundice in dogs with hepatitis. Nine fibrosis-related genes were assayed: PDGFB, PDGFD, MMP2, TIMP1, THBS1, COL1A1, COL3A1, TGFB1, and TGFB2. Liver samples of 15 dogs with chronic hepatitis and 4 healthy control dogs were obtained via laparoscopic biopsy and subjected to histologic and quantitative PCR analyses. The expression of all 9 genes showed significant positive correlation (P<.01, r>.70) with the degree of fibrosis. Furthermore, the expression levels of all genes except TGFB1 were significantly higher (P<.05) in dogs with hepatic failure-related symptoms (ascites/jaundice). Results suggest that these 9 genes are integral to the development of fibrosis in canine chronic hepatitis.

Abstract
BACKGROUND We investigated whether lipopolysaccharide (LPS) induced inflammation in alveolar epithelial type II (ATII) cells is through cluster of differentiation 14 (CD14) and Toll-like receptor 4 (TLR4) and the effect of different dosages of propofol on the inflammation in primary cultured rat ATII cells. METHODS Cultured ATII cells were randomly assigned to one of the following five groups: Group C: untreated group (control) cultured in the absence of propofol and LPS; Group LPS: treated with 1 microg/ml LPS; Group P1: treated with 1 microg/ml LPS and 25 microM propofol; Group P2: treated with 1 microg/ml LPS and 50 microM propofol; Group P3: treated with 1 microg/ml LPS and 100 microM propofol. ATII cells in all groups were cultured at 37 degrees C for 3 h. CD14 and TLR4 mRNA was detected using real-time polymerase chain reaction. Western blot was used to detect CD14 and TLR4 protein expression. CD14 and TLR4 expression on the ATII cells was imaged using immunofluorescence. Tumor necrosis factor-alpha (TNF-alpha) production was determined using an ELISA kit. RESULTS LPS stimulation resulted in an increased CD14 and TLR4 expression and increased TNF-alpha production in ATII cells. Propofol, at concentrations > or = 50 microM, significantly (P<0.05) and dose-dependently decreased CD14 and TLR4 mRNA expression and protein expression in ATII cells. This was accompanied by a decrease in TNF-alpha production (P<0.05). CONCLUSION These results suggest that propofol, at clinically relevant concentrations, can reduce inflammatory responses in LPS-induced ATII cells injury through downregulation of CD14 and TLR4 expression.

Abstract
We report herein a case of collagenofibrotic glomerulonephropathy in a 3-year-old Shiba Inu with severe proteinuria. Histologically, renal glomeruli were enlarged with massive deposition of a homogeneous eosinophilic substance within the mesangium and capillary walls. The deposits reacted weakly with periodic acid-Schiff, stained deep blue with Masson's trichrome, and were positive by immunofluorescence for type III collagen and fibronectin. Ultrastructurally, the deposits consisted of fibrils and amorphous material in the mesangial matrix and beneath the glomerular capillary endothelium. The fibrils had transverse bands analogous to those of collagen fibrils. Electron microscopy also revealed focal detachment of podocytes and foot process effacement in glomerular tufts, which suggested that podocyte injury had contributed to the development of proteinuria in this dog. The current case resembles collagenofibrotic glomerulonephropathy (CFGN) in humans in histopathologic, immunofluorescence, and electron microscopic findings. This is the first report of CFGN in a nonhuman species with glomerular deposition of fibronectin and type III collagen.

Abstract
BACKGROUND The dose of milrinone should be reduced in patients with renal failure. However, there is little data examining the relationship between plasma concentration of milrinone (pCmil) and renal function in intravenous infusion. METHODS We evaluated the pCmil relative to renal function during intravenous infusion. We enrolled 10 heart failure patients. Milrinone was continuously infused at a rate of 0.2 microg/kg/min. Blood samples were collected at 6, 12, 24, and 48 h after the beginning of infusion. Urine was sampled during the first 24 h to calculate creatinine clearance (CLcr) and renal clearance of milrinone (rCLmil). RESULTS The pCmil exhibited stability over 6 h after the beginning of infusion. During the first 24 h, CLcr and rCLmil were 62.2+/-30.6 ml/min and 1.67+/-0.77 ml/kg/min (106.2+/-60.3 ml/min), respectively. The rCLmil was highly correlated with CLcr. Y=1.77X-3.89 (X, CLcr; Y, rCLmil; R(2)=0.809, P<0.0001). Significant correlations were observed between CLcr and the plasma concentration during the continuous infusion. This correlation was expressed as the equation Y=51.1 x (BW/X)+28.2 (X; CLcr, Y; plasma concentration; BW, body weight; R(2)=0.695, P<0.01). CONCLUSION The pCmil exhibited stability 6 h or later after the continuous infusion of milrinone 0.2 microg/kg/min. The pCmil can be estimated by the value of CLcr and BW.

Abstract
OBJECTIVES To prospectively examine the association of cigarette smoking and alcohol drinking with oral and pharyngeal carcinogenesis, we analyzed data from a nation-wide large-scale cohort study in Japan. METHODS A total of 34 136 men and 43 711 women aged 40-79 years were included in the study. The Cox proportional hazard model was used to estimate the relative risk (RR) and 95% confidence interval (95% CI) of oral and pharyngeal cancer for smoking and drinking by sex, while adjusting for age, consumption of green tea, preference for salty foods, and consumption of green yellow vegetables. RESULTS Current smokers were found to have a higher risk of death caused by oral and pharyngeal cancer compared with non-smokers in both sexes: the RR was 2.6 (95% CI: 1.0-6.7) in men and 8.2 (95% CI: 2.1-32.1) in women. Men who drank more than 46 g ethanol per day had an approximately threefold increased risk of oral and pharyngeal cancer. Simultaneous exposure to both factors was significantly associated with an elevated risk of oral and pharyngeal cancer (RR: 3.3, 95% CI: 1.1-9.6). CONCLUSIONS The result supports the carcinogenic effect of cigarette smoking and alcohol drinking on the oral cavity and pharynx.

Abstract
Several studies have reported positive associations between oral infections and systemic diseases. The purpose of the present study was to evaluate the effects of oral symptoms on mortality from cardiovascular disease (CVD) and pneumonia. Using data from a cohort study in Japan, we analyzed 4,139 individuals aged 40–79 years. The baseline questionnaire included the following items related to oral symptoms: ‘sensitive teeth’, ‘difficulty in chewing tough food substances’, ‘bleeding gums’, and ‘mouth feels sticky’. We used the Cox proportional hazard model to estimate hazard ratios (HRs) and 95% confidence intervals (95%CIs) for mortality, after adjustments for lifestyle, socio-economic factors, and history of diseases. Persons complaining that their ‘mouth feels sticky’ had a two-fold higher risk of pneumonia (HR = 2.1; 95%CI, 1.2–3.6), while those complaining of ‘sensitive teeth’ had a lower risk of CVD (HR = 0.4; 95%CI, 0.2–0.9). Some oral symptoms may be predictors of mortality from pneumonia and CVD.

Abstract
AIMS To identify an extreme thermophile, strain TMY, isolated from silica scale from the geothermal electric power plant and to examine microdiversity of Thermus thermophilus strains. MATERIALS AND RESULTS The isolated strain TMY was identified by morphological, biochemical and physiological tests. Phylogenetic comparison of the strain and other Thermus strains with 16S rDNA analysis, RAPD and ERIC-PCR fingerprinting were performed. Strain TMY was closely related to strain which was isolated from a hot spring in New Zealand and shown to belong to the Japanese Thermus cluster. However, there were considerable genetic differences between strain TMY and other Thermus species using DNA fingerprinting. CONCLUSIONS Based on morphological, physiological and genetic properties, strain TMY could be a strain of T. thermophilus. The distinct properties of strain TMY suggest that microdiversity of T. thermophilus strains should be considered. SIGNIFICANCE AND IMPACT OF THE STUDY The results of this study have demonstrated genetic diversity within T. thermophilus strains, which were previously masked by an almost identical 16S rDNA sequence. RAPD and ERIC-PCR could be potential methods for distinguishing between Thermus strains.

Abstract
A 50% to 75% early graft loss upon engraftment has been suggested to in intraportal islet transplantation (IPIT). Hypoxia in the portal vein contributes to graft loss in immediately posttransplantation. Herein we examined the effect on the outcome of IPIT of intraperitoneal oxygenated perfluorochemical (PFC) as an oxygen carrier. Isolated Lewis rat islets were transplanted into the portal vein of a chemically induced diabetic syngeneic rat. First, 1500 IEQ was determined to be the optimal dose in this study. When oxygenated PFC (group 1) was intraperitoneally injected following IPIT of 1500 IEQ, the success rate of transplantation was 5/6, in contrast to 1/6 when PFC with no oxygen was injected (group 2) and 1/6 in IPIT without PFC, respectively. The area under the glucose profile curve on intraperitoneal glucose tolerance tests on posttransplant day 28 in group 1 was significantly smaller than that for group 2. In conclusion, intraperitoneal oxygenated PFC improved the outcome of IPIT.

Evaluation of the mechanical strength and patency of functional end-to-end anastomoses. Surg Endosc 2007; 21:1508-11.

Abstract
BACKGROUND Although many mechanical devices are being developed for functional end-to-end anastomosis (FETEA), the best choice remains to be determined. The mechanical strength of each device is an important factor associated with anastomotic leakage. In turn, anastomotic patency is related to postoperative stenosis. This study examined the bursting pressure and circumference of several FETEAs. METHODS Young domestic pigs were used in this study. In experiment 1, a 10-cm segment of intestine was transected using an EndoGIA 60 blue, EndoGIA 60 green, or GIA 60 blue stapler, and the bursting pressure of each instrument's mechanical staple line was examined. In experiment 2, after FETEA had been created with EndoGIA 60 blue, the bursting sites were examined, and the bursting pressures of buttressed and nonbuttressed FETEA were measured and compared. In experiment 3, the circumference of FETEA was compared between the closed technique and reinforcement. RESULTS The bursting pressure of EndoGIA 60 blue was significantly higher than that of the other devices. When an anastomotic crotch was buttressed, the bursting pressure (44 +/- 13 mmHg) was significantly increased over that of the nonbuttressed FETEA (27.5 +/- 5.8 mmHg; p < 0.05). The circumference of FETEA using the wide technique (92.7 +/- 2.3 mm) was larger than that using the offset technique (55.7 +/- 5.8 mm). CONCLUSIONS The bursting pressure of the mechanical staple line using the EndoGIA 60 stapler was the strongest. Functional end-to-end anastomosis was stronger when created with buttress of an anastomotic crotch, and larger circumferences were created with the wide technique.
