Abstract
AIM Endometrial biopsy is generally performed with a metal uterine curette sonde; however, recently, many types of vacuum aspirators are available, including the manual vacuum aspiration (MVA) system. We used the women's MVA system for endometrial sampling and evaluated its effectiveness in determining the presence of endometrial malignancy. METHODS Forty-seven samples were examined using the following procedures after measuring endometrial thickness by transvaginal ultrasonography: fractional curettage biopsy (Bx; 20 samples), total curettage under general anesthesia (T/C; 13 samples), and MVA (14 samples). The quality of the endometrial samples was classified into four types: 1-4, where 1 denoted poor and 4, good quality. RESULTS The mean score of the MVA group was significantly higher than that of the partial curettage biopsy group (p = 0.0065). No differences were observed between the MVA and total curettage groups (p = 1.00). When patients were divided into two groups according to endometrial thickness (<10 mm or ≥10 mm) and analyzed, both the MVA and T/C groups did not show a significant difference in their scores compared to the Bx group when the endometrial thickness was <10 mm. However, when the endometrial thickness was ≥10 mm, the MVA and T/C groups had significantly better scores than the Bx group (p = 0.0225 and p = 0.0244, respectively). Vagal reflex, as an adverse event, was observed only in two patients in the Bx group (2/20, 10%). CONCLUSION Considering its quality and safety, Karman-type MVA for endometrial sampling could be an alternative to fractional curettage using a metallic uterine curette sonde.

Abstract
Objective Among treatment options for coronavirus infectious disease 2019 (COVID-19), well-studied oral medications are limited. We conducted a multicenter non-randomized, uncontrolled single-arm prospective study to assess the efficacy and safety of favipiravir for patients with COVID-19. Methods One hundred participants were sequentially recruited to 2 cohorts: cohort 1 (Day 1: 1,600 mg/day, Day 2 to 14: 600 mg/day, n=50) and cohort 2 (Day 1: 1,800 mg/day, Day 2 to 14: 800 mg/day, n=50). The efficacy endpoint was the negative conversion rate of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), and the odds ratio (OR) of cohort 2 to cohort 1 for negative conversion on Day 10 was calculated. Characteristics of all participants and profiles of adverse events (AEs) were collected and analyzed. Results The mean age of participants was 62.8±17.6 years old. Thirty-four patients (34.0%) experienced worsening pneumonia, 7 (7.0%) were intubated, and 4 (4.0%) died during the observation period. Cohort 2 showed a higher negative conversion rate than cohort 1 [adjusted OR 3.32 (95% confidence interval (CI), 1.17 to 9.38), p=0.024], and this association was maintained after adjusting for the age, sex, body mass index, and baseline C-reactive protein level. Regarding adverse events, hyperuricemia was most frequently observed followed by an elevation of the liver enzyme levels (all-grade: 49.0%, Grade ≥3: 12.0%), and cohort 2 tended to have a higher incidence than cohort 1. However, no remarkable association of adverse events was observed between patients <65 and ≥65 years old. Conclusion The antiviral efficacy of favipiravir was difficult to interpret due to the limitation of the study design. However, no remarkable issues with safety or tolerability associated with favipiravir were observed, even in elderly patients with COVID-19.

Abstract
Abstract
Introduction
Postprocedural High platelet reactivity (HPR) seems to associate long term adverse cardiovascular events, mainly intrastent thrombosis. However, the relationship between hyper-acute postprocedural HPR with prasugrel loading and clinical outcomes in acute coronary syndrome (ACS) is still unclear. Moreover, factors contributing HPR in ACS with prasugrel loading are also unknown.
Purpose
This study aimed to assess the impact of hyper-acute postprocedural HPR with prasugrel loading on clinical outcomes in ACS during hospitalization, as well as to define appropriate cut-off values and identify contributing factors of HPR.
Methods
We performed a single-centre, retrospective observational study that enrolled 207 patients who underwent emergent PCI for ACS with prasugrel loading. The P2Y12reaction unit (PRU) value was measured immediately after PCI with the VerifyNow System. The primary endpoint was major adverse cardiac events (MACE, defined as the composite of death, myocardial infarction, stroke, heart failure, ventricular arrhythmia needing defibrillation).
Results
Mean patient age (standard deviation) was 70.5 (±13.0) years, 78.7% were male, and average time from prasugrel intake to PRU calculation was 98.3 (±49.1) min. During a mean hospital stay of 15.9 (±9.3) days, there were 34 in-hospital MACE (16.4%) and 10 deaths (4.8%). Thrombosis events, didn't stand out and mechanical complications, such as cardiac rupture and cardiac tamponade occupies most of cardiovascular death which occurred before 10 days on admission. PRU was significantly higher in MACE group than Non-MACE group (279±65 vs 227±72, p<0.001 respectively). The ROC curve analysis of PRU for discriminating significant in-hospital MACE showed the cut off value of 293 (sensitivity:52.9%, specificity:83.2% [AUC=0.709, p<0.0001]). 47patients (29.4%) were thus categorized as HPR (PRU>293) immediately after emergent PCI. Kaplan-Meyer curve showed MACE events occurred in HPR group than non-HPR group (38.2% vs 10.0%, p<0.001). Multiple cox analysis demonstrated that HPR was independent predictors of MACE in patients with ACS underwent PCI (OR 5.416, 95% CI 2.157–13.598, p<0.0001). Multiple logistic regression model showed female sex, low haemoglobin value, and large mean platelet volume were independent predictors of HPR.
Conclusion
PRU was significantly higher in MACE group, and appropriate cut-off value of HPR in this study was 293. HPR was independent predictor of MACE during hospitalization, however thrombosis event was not significant. Evidence of clinical impact with postprocedural HPR within 120 minutes after prasugrel loading is scarce. This study shows post-procedural HPR, even without sufficient time after prasugrel intake, can be a useful predictive marker of adverse events during hospitalization.

Abstract
Abstract
Background
Patients with diabetes mellitus are at very high risk for obstructive coronary artery disease; however, invasive coronary angiography is not allowed to apply in all patients. Cardio-ankle vascular index (CAVI), a marker of arterial stiffness has been reported to reflect atherosclerotic burden.
Purpose
To assess the diagnostic performance of CAVI vs. coronary calcium score for detecting obstructive coronary artery disease determined by Coronary CT angiography (CCTA) in asymptomatic diabetes patients.
Methods
During May 2015 to December 2019, 816 patients with diabetes mellitus were evaluated. First, intima-media thickness of carotid artery was measured in all subjects. Then, patients with intima-media thickness over 11mm underwent CAVI. Finally, 209 patients who have one or more cardiovascular risk factors other than diabetes mellitus were enrolled (68±11 years, 68% men). Patients were excluded if they had a disorder of the kidney, a prior history of coronary artery revascularization, atrial fibrillation, LV ejection fraction <50%, ABI <0.9 or allergy to contrast. Diagnostic performance of CAVI was evaluated with coronary stenosis >50% by CCTA.
Results
CAVI, Agatston score, and intima-media thickness of carotid artery were 9.2±1.3, 396±621 and 2.0±0.7mm, respectively. CAVI was significantly correlated with age (r=0.530, p<0.001), coronary artery calcification (r=0.182, p=0.008), and intima-media thickness of carotid artery (r=0.195, p=0.005). Among them, 108 patients (48%) had coronary stenosis. CAVI, Agatston score and intima-media thickness of carotid artery in patients with coronary stenosis were higher than that without coronary stenosis, respectively (9.8±1.1 vs 8.5±1.0, p<0.001, 526±676 vs. 255±525, p=0.001, 2.2±0.7 vs. 1.8±0.6, p<0.001). The ROC curve analysis of CAVI for discriminating coronary stenosis showed that the sensitivity 75.0% and specificity 77.2% at the cut off value of 9.23 (AUC=0.812, p<0.001). Contrastingly, diagnostic performance of coronary calcium score and intima-media thickness of carotid artery were less than CAVI (sensitivity: 91.7%, specificity: 56.4%, AUC=0.753, p<0.05 vs. CAVI, sensitivity: 68.5%, specificity: 59.4%, AUC=0.663, p<0.05 vs. CAVI). Multivariate logistic analysis demonstrated that CAVI was significantly associated with coronary stenosis (OR=4.133, p<0.001) after adjustment of conventional risk factors, although coronary calcium score was not correlated with coronary stenosis.
Conclusion
CAVI could be informative to select patients having obstructive coronary artery disease in asymptomatic diabetes patients with thick intima-media thickness.

Abstract
Abstract
Background/Introduction
Previous studies demonstrated that high platelet reactivity (HPR) predicts future cardiovascular death and coronary events in patients undergoing percutaneous coronary intervention (PCI) for acute coronary syndrome (ACS). However, few studies have focused on the impact of HPR on left ventricular remodeling (LVR) and each echocardiographic parameter.
Purpose
The purpose of this study was to investigate the impact of HPR in ACS patients on LVR and changes in echocardiographic volume indexes and LV ejection fraction.
Methods
This is a retrospective cohort study of prospectively collected data in a single center that enrolled patients who underwent emergency PCI for ACS including STEMI and NSTEMI with prasugrel loading. The primary outcome of the study was LVR associated with HPR. Secondary endpoints were changes in indexed LVESV, LVEDV, LVEF, E/e' and LAVI between baseline and follow-up. The P2Y12 reaction unit (PRU) value in response to prasugrel was assessed by the VerifyNow P2Y12 assay. Blood samples were collected once per procedure immediately after PCI. LVR index was calculated as the relative change in LVEDV observed at follow-up compared with baseline. LVR was defined as a relative increase in LVEDV ≥20%, measured at follow-up visit compared with the baseline value before discharge.
Results
A total of 196 ACS patients who underwent emergency PCI between January 2016 and July 2020 were enrolled in the study. The mean age of the study population was 69.9 years, and 76.0% were male. On echocardiography at follow up visit of mean duration of 7.0±4.0 months, LVR was found in 38 patients (19.4%). The optimal cutoff for PRU associated with increased LVR assessed by receiver-operating characteristic curve analysis was 245.5 (AUC: 0.656; 95% CI: 0.564 to 0.749; p=0.003). On the basis of this cutoff, HPR was found in 82 patients (42.1%) and the prevalence of LVR was significantly higher in the HPR group compared to the non-HPR group (30.5% vs. 11.4%; p=0.001). Multiple Cox regression analysis showed that HPR was an independent predictor of LVR (OR 4.22, 95% CI 1.83–9.71, p=0.001). In addition, Δ% EDV and Δ% ESV increased in the HPR group, and decreased in the non-HPR group with significant differences (5.8±32.6% vs. −8.0±26.2% in Δ% EDV; p=0.002, 2.0±37.5% vs. −13.3±33.0% in Δ% ESV; p=0.004, respectively). Δ%EF, Δ%E/e', Δ%LAVI were numerically improved in the non-HPR group compared with the HPR group, but this difference did not reach statistical significance.
Conclusion
In patients with ACS, HPR defined as PRU ≥246 immediately after emergency PCI was an independent predictor of LVR in the chronic phase.

Abstract
Abstract
Background
Recent ESC/EAS Guidelines for the management of dyslipidemia stated that the treatment goal of LDL cholesterol (LDL-C) in very high-risk patients is less than 55mg/dl. PCSK9 inhibitors in addition to strong statins could be a useful strategy for rapid and aggressive lowering of LDL-C. However, the feasibility and safety of early initiation of a PCSK9 inhibitor for AMI patients undergoing primary PCI remain unclear.
Objectives
We examined the effects of early initiation of a PCSK9 inhibitor, evolocumab, on lipid profile and inflammatory markers and its safety in AMI patients undergoing primary PCI.
Methods
This study is a single center, randomized, controlled trial involving 102 patients hospitalized for AMI. The patients were randomly assigned 1:1 to the evolocumab group and the control group. Evolocumab (140 mg) was subcutaneously injected within 24 hours after PCI and then every two weeks. All patients received pitavastatin (2mg/day) in addition to the allocated treatment. The primary endpoints were changes in lipid profile and inflammatory markers from baseline to 4 weeks.
Results
102 patients were enrolled between October 2017 and December 2019. 89 patients were ST-segment elevation myocardial infarction (STEMI), 13 patients were non-STEMI. Primary PCI was successfully performed in all patients. 76 patients were statin-naïve. 2 patients were excluded from analyses because they died severe heart failure in acute phase. Finally, 100 patients (evolocumab; n=51 and control; n=49) were analyzed. Baseline LDL-C was 121.6±30.3 mg/dl in the evolocumab group and 124.7±33.6 mg in the control group. Change in LDL-C from the baseline to 4 weeks was −92.4±32.4 mg/dl (−75%) in the evolocumab group and −44.8±32.1 mg/dl (−33.1%) in the control group (mean difference; 47.6mg/dl, 95% CI; 34.8 to 60.4 mg/dl, p<0.001). LDL-C <70mg/dl at 4 weeks was achieved in 96.0% of the evolocumab group as compared with 26.5% of the control group. Further, in the evolocumab group. LDL <55mg/dl was achieved in 92.1% at 2 weeks and 92.1% at 4 weeks. Regarding inflammatory markers, there were no significant difference in change in high-sensitivity C-reactive protein (p=0.49) and tumor necrosis factor-alpha (p=0.63) between two groups even after adjustment of baseline value. No adverse event associated with evolocumab was observed during this study.
Conclusion
In patients with AMI undergoing primary PCI, early initiation of evolocumab rapidly reduced LDL-C without no adverse event, and achieved LDL-C<55mg/dl in most patients within 2 weeks. Early administration of a PCSK9 inhibitor combined with a strong statin could be a feasible and safe treatment for AMI patients undergoing PCI.

Abstract
OBJECTIVE To assess the effectiveness of an HPV vaccination programme in reducing the risk of cervical abnormalities identified at subsequent screening. DESIGN Retrospective cohort study using administrative health data. SETTING General population of Ferrara Province, Italy. POPULATION Female residents born in 1986-1993 and participating in the organized cervical screening programme in 2011-2018, who were eligible for HPV vaccination in catch-up cohorts. METHODS Logistic regression to evaluate the potential association between abnormal cervical cytology and one, two, three or at least one dose of HPV vaccine. MAIN OUTCOME MEASURES Cervical abnormalities, as predicted by low-grade or high-grade cytology, by number of vaccine doses, stratified by age. RESULTS The sample consisted of 7785 women (mean age 27.5 years, SD 2.3). Overall, 391 (5.0%) were vaccinated with ≥1 dose and 893 (11.5%) had abnormal cytology. Women receiving at least one vaccine dose were significantly less likely to have an abnormal cytology (adjusted odds ratio 0.52; 95% confidence interval 0.34-0.79). Similar results were observed for women receiving a single dose, for both bivalent and quadrivalent vaccines, and applying buffer periods (excluding cytological outcomes within 1 month, 6 months and 1 year of the first dose). CONCLUSIONS In the context of an organised cervical screening programme in Italy, catch-up HPV vaccination almost halved the risk of cytological abnormalities. TWEETABLE ABSTRACT Among Ferrara women, vaccination against human papillomavirus halved the risk of screening cervical abnormalities.

Abstract
Background: In 2016, gastric cancer is the second leading cause of cancer mortality worldwide. Globally, Japan and Korea are the only two countries implementing national screening program for gastric cancer. South Korea launched a biennial national -endoscopic screening program in 1999, which demonstrated a 47% reduction in gastric cancer mortality compared with no screening. In 2015, endoscopic screening was recommended by the Japanese Guideline for Gastric Cancer Screening. Currently, Japan's screening policy recommends endoscopic screening every 2 to 3 years for individuals aged 50 or above. Aim: This study aims to quantify the potential impacts of Japan's current national endoscopic screening policy and other alternative endoscopic screening options, and to identify a set of efficient endoscopic screening strategies for the current population of Japan. Methods: A microsimulation model of intestinal-type noncardia gastric adenocarcinoma was developed to simulate a virtual population with similar risk profile and life expectancy to the actual population of Japan. The model was calibrated and validated to the nationally-representative data from vital statistics and population-based cancer registries. The baseline scenario was modeled to project the current trend of gastric cancer. Variations among age of initiation (40, 45, 50, and 55), age of termination (75, 80, and 85), and screening interval (2, 5, 10, and 15 years) resulted in 39 unique endoscopic screening strategies for evaluation. In addition, the following three existing screening scenarios were included for analysis: the current screening program in Japan (screening every two or three years from age 50 years, with no termination) and Korea (biennial screening from age 40 years, with no termination). In total, 42 unique endoscopic screening strategies were simulated. Full adherence for all screening scenarios were assumed. Results: In comparison with baseline scenario, endoscopic screening strategies provided 43 to 203 life-years gained per 1000 individuals. The number of lifetime endoscopies per 1000 individuals ranged from 2281 to 28,635. The complications caused by screening were from 6 to 77 per 1000 individuals. The lifetime number of false-positive results ranged from 381 to 4941 per 1000 individuals. Scenarios simulating the current national endoscopic screening program in Japan and Korea fell below the efficient frontier. Under full adherence assumption, the most advantageous endoscopic screening strategy among evaluated scenarios is screening from age 40 to 80 years every 5 year. Conclusion: In this microsimulation modeling study with full adherence assumption, the findings suggest that the current national endoscopic screening program for gastric cancer in Japan might not be the most efficient screening option under benefit-to-harm consideration. The finding underpins the need for further investigation to bring up an efficient and cost-effective endoscopic screening program in Japan.

Abstract
OBJECTIVES In Japan, approximately 7000 smear-positive tuberculosis (TB) cases were reported in 2014. According to the law, such patients must be isolated in a TB ward until they become at least sputum smear-negative. However, there are some recalcitrant patients who are difficult to isolate because of problematic behaviors. This study was conducted to characterize recalcitrant TB patients and determine why they left the hospitals and how they were followed up after they left. STUDY DESIGN Cross-sectional study. METHODS We sent a self-administered questionnaire to the hospitals in Japan with over 11 TB isolation beds, asking about recalcitrant TB inpatients from April 2013 through March 2014, in terms of demographic information, the reasons why they left, and how they were followed up. RESULTS A total of 38 recalcitrant patients were reported, of whom 15 (39.5%) self-discharged, eight (21.0%) were discharged, and 15 (39.5%) were transferred. Thirty-three (86.8%) were males. The main reason (52.6%) why the patients were considered recalcitrant was related to psychiatric problems. However, nine (23.6%) patients physically assaulted or insulted the staff members. Thirty-six (94.7%) were able to continue anti-TB treatment after they left the original hospital. CONCLUSION Although the number of recalcitrant TB patients who were abusive was small, there should be TB facilities with law enforcement officials readily available to enforce isolation.

Abstract
Subtypes of stx1 and stx2 in 45 Shiga toxin-producing Escherichia coli (STEC) strains isolated from cattle were investigated by PCR. Only subtype stx1a was detected among all the stx1-positive strains. The major stx2 subtype was stx2a followed by stx2d, stx2c, stx2b, and stx2g in decreasing order of frequency. stx2c was found in strains of serotypes O157 and O174. stx2d was found in 11 strains. These strains were confirmed by DNA sequencing to carry both the activatable tail and the END motif; all were eae-negative, and 3 contained stx2d as the only stx. stx2g was found in 2 strains in association with stx2a, estA1, and astA. In addition, 7 hybrid strains of shigatoxigenic and enterotoxigenic E. coli (STEC/ETEC) were found to harbor one or both of stx1a and stx2a (stx1a/stx2a) and estA1. Among 27 serotypes of STEC strains isolated from cattle, O157:H7 and O109:H- strains were eae-positive. Other putative adhesin genes, such as saa, iha, espP, and lpfAO113 were detected in more than 12 serotypes.

Abstract
38% of Native Hawaiian, 34% of Japanese, 33% of Filipino, 23% of Chinese and 19% of White inpatients had diagnosed diabetes. 3% Native Hawaiian, 3% Japanese, 4% Filipino, 4% Chinese and 4% White inpatients had potentially undiagnosed diabetes. Few potentially undiagnosed diabetes cases were found. Prospective methods are recommended. Potentially undiagnosed diabetes was associated with a longer hospital stay and higher mortality. Inpatient diabetes screening with HbA1c is suggested, which should be evaluated prospectively for improved outcomes.
Aims Little is known about diabetes in hospitalized Native Hawaiians and Asian Americans. We determined the burden of diabetes (both diagnosed and undiagnosed) among hospitalized Native Hawaiian, Asian (Filipino, Chinese, Japanese), and White patients. Methods Diagnosed diabetes was determined from discharge data from a major medical center in Hawai‘i during 2007–2008. Potentially undiagnosed diabetes was determined by Hemoglobin A1c ≥ 6.5% or glucose ≥ 200 mg/dl values for those without diagnosed diabetes. Multivariable log-binomial models predicted diabetes (potentially undiagnosed and diagnosed, separately) controlling for socio-demographic factors. Results Of 17,828 hospitalized patients, 3.4% had potentially undiagnosed diabetes and 30.5% had diagnosed diabetes. In multivariable models compared to Whites, Native Hawaiian and all Asian subgroups had significantly higher percentages of diagnosed diabetes, but not of potentially undiagnosed diabetes. Potentially undiagnosed diabetes was associated with significantly more hospitalizations during the study period compared to both those without diabetes and those with diagnosed diabetes. In all racial/ethnic groups, those with potentially undiagnosed diabetes also had the longest length of stay and were more likely to die during the hospitalization. Conclusions Hospitalized Native Hawaiians (41%) and Asian subgroups had significantly higher overall diabetes burdens compared to Whites (23%). Potentially undiagnosed diabetes was associated with poor outcomes. Hospitalized patients, irrespective of race/ethnicity, may require more effective inpatient identification and management of previously undiagnosed diabetes to improve clinical outcomes.

Abstract
Pathogenic genes such as stx1, stx2, STh gene, STp gene, LT gene, invE, eae, aggR, afaD, astA, cdt and cnf were investigated in Escherichia coli isolated from cattle during Nov. 2012 and Aug. 2013. Plural pathogenic genes were concurrently detected by multiplex PCR, and screen-positive genes were confirmed and sub-classified by PCR. Among 100 cattle investigated, 180 E. coli strains with diarrheic genes (DEC) were detected in 79 cattle, and 45 of them, isolated from 32 cattle, were Shiga toxin-producing E. coli (STEC). More than 30% of cattle carried astA, cdt, cnf and stx2 in descending order. STh gene, LT gene, invE, aggR and afaD were not detected in this study. Both stx1 and stx2 were concurrently detected from 6 of 45 STEC strains and stx2 alone was detected from 19. Seventeen STEC strains carried STp gene, astA, or cdt along with stx1 or stx2. Additionally, 135 remaining DEC were classified into 18 enterotoxigenic E. coli with STp gene, 25 enteropathogenic E. coli with eae, and 92 other DEC with astA, cdt and cnf. Both O and H serotypes were identified in 48 strains, including O157 : H7, O1H7 and so on. O157 : H7 were identified in 3 strains that carried stx2 and eae together, as found in human pathogenic strains isolated from patients with gastroenteritis and hemolytic-uremic syndrome.

Abstract
In this study, the effect of ovarian cavity fluid (OCF) from a surfperch Neoditrema ransonnetii on the cytotoxic activity of leucocytes was investigated. In an assay targeting RTG-2, a cell line derived from rainbow trout Oncorhynchus mykiss gonads, leucocytes from both the spleen and head kidney showed spontaneous killing activity. Pre-incubation with OCF significantly suppressed the cytotoxic activity of head-kidney leucocytes towards RTG-2. This suppressive activity was due to the presence of low molecular-mass materials. These results suggest that OCF plays significant roles in pregnancy by its ability to modulate cytotoxicity with maternal leucocytes.

Abstract
A simultaneous screening method using conventional PCR was developed for the detection and discrimination of Bordetella pertussis, Bordetella parapertussis, and Bordetella holmesii. A formulated multiprex method employing 4 kinds of paired primers on amplification of 4 corresponding different insertion sequences (IS481, IS1001, IS1002 and hIS1001) enabled rapid screening and identification. The detection limits of each DNA extracted from 3 kinds of Bordetella species were 5fg/microL for each. Obscure existences of B. pertussis and B. holmesii at low levels were confirmed with the LAMP method. This multiplex assay was applied to the clinical specimens obtained from patients with pertussis-like symptoms at sentinel clinics under the epidemiological surveillance of infectious diseases of Hyogo prefecture in FY2012. Among 42 nasopharyngeal swabs, B. pertussis was detected from 12 samples including 8 samples collected at outbreak in nursery school. The use of this method for the surveillance of infectious agents enabled us to search for 3 kinds of Bordetella species at once with low costs.

Abstract
Aspergillus oryzae KB produces two types of beta-fructofuranosidases: F1 and F2. F1 produces the fructooligosaccharides (FOSs) 1-kestose, nystose, and fructosyl nystose from sucrose through a transfructosylation action, whereas F2 mainly hydrolyzes sucrose to glucose and fructose. F1 and F2 enzymes were more selectively produced from the KB strain in liquid media with a sucrose concentration>2% and <2%, respectively. Immobilization using an anion-exchange resin (WA-30; polystyrene with tertiary amine) and cross-linking with glutaraldehyde depressed the hydrolysis reaction of F2 (high hydrolyzing enzyme) alone and enhanced the thermal stability of F1 (high transferring enzyme). F1 enzyme produced in the high sucrose medium was immobilized, cross-linked, and packed in a tubular reactor for continuous production of FOSs (24.6% 1-kestose, 21.6% nystose, 5.7% and fructosyl nystose). In a long-term operation in which 60% sucrose was imputed at 55 degrees C, the composition of FOSs produced was 51.9% (transfer ratio: 92%), and production by the immobilized enzyme was maintained for 984 h.

Abstract
A protein kinase inhibitor UCN-01 binds with high affinity to human alpha 1-acid glycoprotein (hAGP) which may compromise the drugs therapeutic effectiveness. Liposomal formulations of UCN-01 have been evaluated as a means of reducing the impact of binding to hAGP. However, in an initial study, UCN-01 was released rapidly from liposomes added to rat plasma containing hAGP. The purpose of this study was to develop a liposomal formulation of UCN-01 that only slowly released drug. Liposomes composed of lipids with a high phase transition temperature and having an average particle size of 120 nm and above reduced leaking of UCN-01 when the formulations were evaluated by adding to rat plasma containing hAGP. Furthermore, formulations composed of larger liposomes were also more effective in vivo; in tests in which liposomal preparations were injected together with hAGP into rats, more UCN-01 was retained in liposomes for 24h after administration of 155 nm liposomes as compared to 112 nm liposomes.

Abstract
Previously, we demonstrated that wrapping dextran fluorescein anionic/cationic lipid complexes with neutral lipids produced a stable formulation that markedly increased the duration of the compound in plasma after intravenous administration to rats. The improved drug-delivery properties of the wrapped liposomes (WL) relative to other formulations suggested that this technology could offer important advantages for the administration of other polyanionic drugs, including antisense oligodeoxynucleotides (ODN). In the present study, we investigated the value of WL for formulating fluorescence-labeled phosphorothioated ODN (F-ODN). WL encapsulating F-ODN/cationic lipid complexes were prepared efficiently using similar methodology to that used in our earlier study. Studies confirmed that these WL were stable in vitro. Following intravenous administration to mice, free F-ODN and naked F-ODN/cationic lipid complexes were rapidly eliminated whereas administration of the WL resulted in high blood concentrations of drug that were maintained for several hours. Additional studies were conducted in mice that were inoculated with tumor cells (Caki-1 xenograft model, human kidney); in these experiments, intravenous administration of WL delivered 13 times more F-ODN to the tumor site than achieved after injection of free F-ODN.

Abstract
Novel wrapped liposomes comprised of polyanion drug and cationic lipid complexes wrapped with neutral lipids were prepared using an efficient, innovative procedure. In this study, dextran fluorescein anionic (DFA) was used as an example of a polyanionic compound. During the process, neutral lipids accumulated around the complexes and eventually covered the complexes. The resulting liposomes were 120-140 nm in diameter and the encapsulation efficiency was up to 90%. In fetal bovine serum, DFA/cationic lipid complexes degraded rapidly but the wrapped liposomes were considerably more stable. Following intravenous administration to rats, DFA/cationic lipid complexes were rapidly eliminated whereas the wrapped liposomes exhibited a much longer blood half-life. These data suggest that DFA is located on the surface of the complexes, but DFA is present inside the wrapped liposomes. The drug-delivery properties of the wrapped liposomes established in the present study suggests that formulations based on this technology could offer important advantages for the administration of many types of drug including antisense oligonucleotides, plasmids and siRNAs which may therefore lead to improved therapeutic effectiveness of this range of drugs. The method of preparation of the wrapped liposomes is so simple that it should be straightforward to adapt to a manufacturing scale.

Abstract
OBJECTIVE To develop an integrated approach for engineering craniofacial scaffolds and to demonstrate that these engineered scaffolds would have mechanical properties in the range of craniofacial tissue and support bone regeneration for craniofacial reconstruction. EXPERIMENTAL VARIABLE Scaffold architecture designed to achieve desired elasticity and permeability. Scaffold external shape designed to match craniofacial anatomy. OUTCOME MEASURE Final fabricated biomaterial scaffolds. Compressive mechanical modulus and strength. Bone regeneration as measured by micro-CT scanning, mechanical testing and histology. SETTING Departments of Biomedical Engineering, Oral/Maxillofacial Surgery, and Oral Medicine, Pathology and Oncology at the University of Michigan. RESULTS Results showed that the design/fabrication approach could create scaffolds with designed porous architecture to match craniofacial anatomy. These scaffolds could be fabricated from a wide range of biomaterials, including titanium, degradable polymers, and degradable calcium phosphate ceramics. Mechanical tests showed that fabricated scaffolds had compressive modulus ranging 50 to 2900 MPa and compressive strength ranging from 2 to over 56 MPa, within the range of human craniofacial trabecular bone. In vivo testing of designed scaffolds showed that they could support bone regeneration via delivery of BMP-7 transduced human gingival fibroblasts in a mouse model. Designed hydroxyapatite scaffolds with pore diameters ranging from 400 to 1200 microns were implanted in minipig mandibular defects for 6 and 18 weeks. Results showed substantial bone ingrowth (between 40 and 50% at 6 weeks, between 70 and 80% at 18 weeks) for all scaffolds, with no significant difference based on pore diameter. CONCLUSION Integrated image-based design and solid free-form fabrication can create scaffolds that attain desired elasticity and permeability while fitting any 3D craniofacial defect. The scaffolds could be manufactured from degradable polymers, calcium phosphate ceramics and titanium. The designed scaffolds supported significant bone regeneration for all pore sizes ranging from 300 to 1200 microns. These results suggest that designed scaffolds are clinically applicable for complex craniofacial reconstruction.

Abstract
BACKGROUND The incidence and severity of non-steroidal anti-inflammatory drugs (NSAIDs)-induced gastro-duodenal ulcer have not been extensively studied in Japan. AIM We performed a prospective study to clarify NSAIDs-induced gastro-duodenal injury, focusing especially on low-dose aspirin (L-A). METHODS Two hundred and thirty-eight patients with bleeding peptic ulcers admitted to our hospital. History of taking NSAIDs and anti-ulcer drugs was obtained from all patients who underwent endoscopic examinations. The lesion scores of patients taking L-A were classified numerically from zero (no lesion) to five (ulcer). RESULTS The NSAIDs were associated with 28.2% of hemorrhagic ulcers. The rates of patients using L-A, loxoprofen, diclofenac, and combination of two of these drugs were 27, 16, 10 and 9%, respectively. Co-administered anti-ulcer drugs were cytoprotective anti-ulcer drugs (27%), H2 receptor antagonists (16%), PPI (4%), and none (53%). In patients taking L-A, H2 receptor antagonists were used most frequently. The HP was positive in 63% of L-A-induced ulcer cases and in 69% of NSAIDs other than low-dose aspirin-induced ulcer cases. The lesion scores of patients taking L-A with H2 receptor antagonists or PPI were significantly lower than those of patients who were taking only L-A (P < 0.05). CONCLUSIONS Approximately one-third of hospitalized patients with NSAIDs-induced hemorrhagic ulcer showed an association with L-A. Prospective randomized controlled trials including H2 receptor antagonists are required to establish preventive efforts aimed at L-A-induced gastro-duodenal injury.

Abstract
Regeneration of connective tissue attachment is the ultimate goal of periodontal therapy. It has been suggested that periodontal ligament cells possess the potential to create new connective tissue attachment. However, as cells from gingiva and alveolar bone occupy the root surface during initial wound healing, population by periodontal ligament cells is limited in vivo. We have been developing a new periodontal regeneration technique using in vitro tissue culture of periodontal ligament remaining on a periodontally involved root. The purpose of this study was to examine the periodontal healing after transplantation of teeth with reduced periodontal ligament that had been cultured in vitro. Twenty-five incisors from four beagles were used. After the teeth were extracted, the periodontal ligament and cementum were removed from coronal part of the roots and the roots were planed. The periodontal ligament of the apical part was retained. Fourteen teeth of the experimental group were transplanted following culture for 6 weeks. Eleven teeth of the control group were similarly prepared and immediately transplanted without tissue culture. Four weeks after transplantation, the specimens were prepared for histological analysis. Downgrowth of junctional epithelium on the root of experimental group was significantly less than control. Most of the root planed surfaces of experimental group were covered with periodontal ligament fibers oriented parallel or inclined to the root surfaces and limited new cementum formation was observed near the apical end of the planed root. There was no significant difference between groups in observations on the root surface with remaining periodontal ligament. From the above results, it was concluded that periodontal tissue culture of teeth with root planed surface and remaining periodontal ligament could reduce the extent of epithelium downgrowth and increase connective tissue adhesion on the root planed surface, as well as minimize damage to remaining periodontal ligament, after transplantation of teeth.

Abstract
Infections by larval stages of tapeworms of the genus Echinococcus (echinococcosis or hydatid disease) are zoonotic infections of major public health importance throughout much of the world. Humans become infected through accidental ingestion of eggs passed in faeces of canid definitive hosts. Tibetan populations of China have some of the highest documented levels of infections by both Echinococcus granulosus and E. multilocularis, the causes of cystic and alveolar echinococcosis, respectively. In this study we measured the prevalence of cystic (CE) and alveolar (AE) echinococcosis disease in Tibetan communities in Qinghai, Province, China, and identified putative risk factors for both infections in these communities. 3703 volunteers in three predominately Tibetan counties of Qinghai were surveyed between June 1997 and June 1998. Parasitic lesions were diagnosed by imaging of characteristic space-occupying lesions in abdominal organs (ultrasound) or the lungs (radiographs). Specific serodiagnostic assays (Dot-ELISA and Em2-ELISA) were performed on sera of positively imaged subjects to further distinguish the disease agent. All participants completed a questionnaire documenting age, sex, education level, occupation, lifestyle (nomadic or settled), slaughter practices, drinking water source, hygienic practice and association with dogs. Data were analyzed using SAS version 8. 6.6% of the volunteers had image-confirmed infection with E. granulosus (CE) and 0.8% had E. multilocularis (AE) infection. The significant univariate factors for echinococcal infection (both CE and AE) included livestock ownership, Tibetan ethnicity, female gender, low income, herding occupation, limited education, water source, age greater than 25 years old, poor hygienic practices, offal disposal practices and dog care. Multivariate analysis revealed that livestock ownership was a significant risk factor for both forms of the disease, as well as age greater than 25 years, female gender, herding occupation, and being nomadic (vs semi-nomadic or settled). No additional significant risk factors were identified among the 344 nomadic participants. Being female and being older than 25 years of age were significant factors among the 1906 semi-nomadic participants. Among the 1445 settled participants, allowing dogs to sleep indoors was statistically significant. Issues such as inadequate assessment of animal ownership, selection bias, disease misclassification, and loss of information may have led to reduction in strength of some risk factor associations and need to be addressed in future epidemiologic analysis of echinococcosis in this population.

Abstract
In 3 adult female cheetahs, induced-superovulation treatment was conducted, by means of 200 IU of pregnant mare serum gonadotropin (PMSG) and 100 IU of human chorionic gonadotropin (hCG) 80 hr after PMSG. The administration of PMSG created a sharp increase in the estradiol-17beta concentration, resulting in 232 pg/ml 8 hr later in one specimen out of three. The hCG administration showed an increase in the progesterone concentration of 2.29 ng/ml 46 hr later. In addition, after direct observation of the ovary surface by laparoscopy, 5 follicles in the right ovary over 2 mm in diameter, and 7 corpora lutea (5 in the right ovary and 2 in the left) were found. It is assumed that ovulation can be induced with hCG after 80 hr on PMSG during a cheetah's diestrus or proestrus.

Abstract
Abstract A 53-year-old woman with diffuse cutaneous systemic sclerosis (dsSSc) who developed muscle weakness in her lower extremities was admitted to our hospital. Computed tomography (CT) of her thoracic spine showed paraspinal and intraspinal calcifications producing severe spinal stenosis. After admission, her neurological symptoms, including muscle weakness and sensory disturbance, rapidly progressed and finally her lower extremities became completely paraplegic. After initiation of diltiazem and bucillamine, her neurological disturbance showed a marked improvement. A CT scan of the thoracic spine after medication showed dominant decrements in both intraspinal and paraspinal calcifications.

Abstract
PURPOSE Few data are available on factors encouraging continued caregiving at home, especially in relation to positive perceptions of caregiving and the care burden. This study was conducted to explore this question. METHODS We collected data from forty caregivers using Visiting nursing station, with structured interviews conducted at home. RESULTS 1. Sixty-five percent of caregivers had positive perceptions of the worth and enjoyment of their work in caregiving. 2. Encouraging continued caregiving was associated with positive perceptions and these are relatively independent of the care burden. 3. Caregivers who had high encouraging continued caregiving were spouses or children of the clients. They had positive attitude to caregiving, an intention to use social services and satisfaction in caregiving. 4. Events from which caregivers felt worth and enjoyment in their work were improvement of client's health conditions, gratitude in client response, learning of care skills and strengthening bonds of family relationship. CONCLUSION The findings suggest it is important to approach caregivers for the positive perceptions, rather than simply by decreasing burden.
