Abstract
In the present work, taste masked particles of acetaminophen (AAP), a highly soluble bitter tasting drug, were developed and ODT containing the taste masked particles were prepared. Taste masked particles of AAP were prepared using different amounts of tetraglycerol polyricinoleate (TGPR) and Eudragit ®E100. Although the drug content ratio and drug recovery decreased with increasing TGPR, drug release from AAP-CR100 particles containing a large amount of TGPR was mostly suppressed for 2 min. Hence, AAP-CR100 was incorporated into ODT as taste masked particles for AAP. Three major disintegrants were used for ODT, and it was confirmed that the tensile strength of all formulations showed applicable hardness for handling. The AAP-CR100-CP(40) formulation containing crospovidone showed the shortest disintegration time and the drug release from AAP-CR100-CP(40) into pH 6.8 test solution was suppressed compared with commercial AAP tablets. Because the drug release from AAP-CR100-CP(40) into the pH 1.2 test solution was rapid, it was suggested that drug release from AAP-CR100-CP(40) is suppressed in the oral cavity, and the drug is released promptly in the stomach. Thus AAP-CR100-CP(40) may be useful as an ODT in which the dissolution of AAP in the oral cavity is suppressed.

Abstract
SETTING: Over the period 1992 to 2006, Japan had tuberculosis (TB) notification rates of about 40 to 20 per 100 000 population. In 1999, the Minister of Health and Welfare of Japan declared a public health emergency based on the resurgence of TB.OBJECTIVE: To
compare the trends of TB notification rates before and after the declaration.DESIGN: This is an ecological study on the trends of TB notification rates. The trends per year in TB notification rates were compared before (1992–1997) and after (2001–2006) the emergency
declaration.RESULTS: The trends in the notification rates for all types of TB and sputum smear-positive TB (SSP-TB) decreased from −3.3% (95% confidence interval [CI] −4.6 to −1.9) and 0.94% (95%CI −0.33 to 2.2), respectively, per year before the declaration
to −5.8% (95%CI −6.3 to −5.3) and −3.3% (95%CI −2.4 to −4.2), respectively, per year after the declaration with statistical significance. Trends in notification rates for both all types of TB and SSP-TB statistically significantly decreased after the declaration
in Fukuoka, Osaka and Saitama Prefectures.CONCLUSION: The declaration of TB as a public health emergency in Japan in 1999 had a positive impact on TB control in Japan and thus TB epidemiology.

Abstract
Background: Japan had a tuberculosis (TB) notification rate of 13.9 per 100 000 population in 2016. Objectives: To characterise TB-related enquiries received by the Research Institute of Tuberculosis, Tokyo, Japan, between January 2014 and December 2016. Design: A descriptive study of the time, place and other attributes of the enquiries. Results: A total of 1864 enquiries were listed for analysis. On average, 51.8 enquiries (range 30-77) were received per month. The enquiry rates were highest for Yamanashi (5.87/100 000) and Kochi (5.77) Prefectures, and lowest in Miyazaki (0.45) and Saga (0.48) Prefectures. Enquirers belonged mostly to local governments (n = 1212, 65%) and health care facilities (n = 386, 21%), and included medical doctors (n = 412, 22%), nurses (n = 926, 50%) and the general public (n = 150, 8.0%). Most enquiries concerned TB diagnosis and treatment (n = 475, 25%), including diagnosis in general (n = 38, 2.0%), laboratory diagnosis (n = 83, 4.5%), anti-tuberculosis treatment in general (n = 62, 3.3%) and the management of comorbidities or adverse events (n = 60, 3.2%), followed by contact investigations (n = 371, 20%). Conclusions: As most enquiries concerned the diagnosis and treatment of TB, the Ministry of Health of Japan should maintain a number of specialised TB institutions with TB clinicians to provide technical assistance.

Abstract
BACKGROUND The optimal level for inferior mesenteric artery ligation during anterior resection for rectal cancer is controversial. The aim of this randomized trial was to clarify whether the inferior mesenteric artery should be tied at the origin (high tie) or distal to the left colic artery (low tie). METHODS Patients were allocated randomly to undergo either high- or low-tie ligation and were stratified by surgical approach (open or laparoscopic). The primary outcome was the incidence of anastomotic leakage. Secondary outcomes were duration of surgery, blood loss and 5-year overall survival. RESULTS Some 331 patients entered the trial between June 2006 and September 2012. The trial was stopped prematurely as recruitment was slow. Seven patients were excluded after randomization but before operation because of procedural changes. High tie and low tie were performed in 164 and 160 patients respectively. The incidence of anastomotic leakage was not significantly different (17·7 versus 16·3 per cent respectively; P = 0·731). The incidence of severe complications requiring intervention was 2·4 versus 5·0 per cent for high and low tie respectively (P = 0·222). In multivariable analysis, risk factors for anastomotic leakage included male sex (odds ratio 4·36, 95 per cent c.i. 1·56 to 12·18) and distance of the tumour from the anal verge (odds ratio 0·99, 0·98 to 1·00). At 5 years there were no significant differences in overall (87·2 versus 89·4 per cent respectively; P = 0·386) and disease-free (76·3 versus 77·6 per cent; P = 0·765) survival. CONCLUSION The level of ligation of the inferior mesenteric artery does not significantly influence the rate of anastomotic leakage. Registration number: NCT01861678 ( https://clinicaltrials.gov).

Abstract
BACKGROUND Among infectious diseases, influenza is the most common cause of infection in Japan and worldwide. We aimed to evaluate the effect of influenza vaccination in kidney transplantation (KTx) recipients. METHODS We retrospectively evaluated the records of 98 participants who underwent KTx at our institution between March 2009 and May 2016. All patients received tacrolimus or cyclosporine, mycophenolate mofetil, and methylprednisolone for maintenance immunosuppression after KTx. In accordance with the criteria of our institution, everolimus was administered for the maintenance of immunosuppression after KTx. We compared the rate of influenza infection during the 2016-2017 season (8 months, from October 2016-May 2017) between KTx patients treated with 1 or 2 doses of influenza vaccine (treatment group, n = 71) and KTx patients who did not receive a vaccine (nontreatment group, n = 27). RESULTS Among patient characteristics, only the prevalence of diabetes mellitus differed significantly between the groups (treatment group: 9.9%, 7 of 71 patients; nontreatment group: 29.6%, 8 of 21 patients; P = .02). Influenza infection occurred at similar rates in the 2 groups (treatment group, 5.63% 4 of 71 patients; nontreatment group: 3.70%, 1 of 27 patients; P = .70). CONCLUSIONS Among KTx patients managed in our institution, treatment with 1 or 2 doses of influenza vaccine did not reduce the rate of influenza infection in the 2016-2017 season, suggesting that influenza vaccination may currently be ineffective in KTx patients.

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
Bioceramic derived from chicken feces (BCX) is a material produced by a sintering process for the purpose of use in animal farms to control livestock infectious diseases. In the present study, BCX at pH 13 was evaluated for the durability of its virucidal activity in simulated field conditions. First it was shown that BCX had activity toward Newcastle disease virus, infectious bursal disease virus, and goose parvovirus within 3 min and toward avian influenza virus (AIV) within 1 hr. BCX was further tested by keeping it under simulated harsh environmental conditions with sunlight for several weeks as well as by repeatedly soaking it with water and drying under sunlight many times. After sampling every 2 consecutive weeks and every 2 (of 9) consecutive resuspensions, BCX was evaluated for its efficacy against AIV. Evaluation under the harsh conditions illustrated that BCX could retain its satisfactory efficacy toward AIV throughout 7 wk and through 9 resuspensions. It is hence concluded that BCX is an excellent material for applying in livestock farming as a trapping disinfectant, due to its efficacy to inactivate various viruses, and that this efficacy is prolonged even under harsh environmental conditions.
