Purpose: We investigated the activity of our palliative care team over the past five years and how the new coronavirus infection (COVID-19) affects palliative care in our hospital. Methods: We retrospectively compared and analyzed patient data intervened by the Tokyo Medical University Hospital Palliative Care Team from April 2016 to March 2021. Results: There were no major differences in the total number of requests, patient background, reasons for request, and reasons for intervention from FY2016 to FY2020. In FY2020, the number of patients with PS0 at the time of request and who discharged from the hospital at home increased significantly compared to other years. Discussion and Conclusion: From the results of this survey, it was found that the introduction of palliative care from an early stage is progressing. On the other hand, because the outbreak of COVID-19 has restricted visits to inpatients at our hospital, it is possible that the proportion of patients who choose home care is increasing. Intervention requests to the palliative care team did not change significantly over the 5-year period without the impact of the COVID-19 pandemic. Strict visitation restrictions for inpatients have become barriers to the practice of palliative care.

Prophylaxis is sometimes offered to inpatients who share a room with, or individuals who have been in close contact with, patients who have contracted influenza. In our hospital, 5-day prophylactic oseltamivir has been used as a standard procedure. Here, we investigated the effectiveness of this post-exposure prophylaxis for inpatients and healthcare professionals, as well as its effect on hospital management. The study period was 5 years from fiscal year 2013 to fiscal year 2017, and the effectiveness outcome was the secondary infection rate. Medication costs for this prophylaxis were compared with those for oseltamivir used according to the package insert. The secondary infection rates were 3.0% and 0.5% in 133 inpatients and 434 healthcare professionals who had received post-exposure oseltamivir, respectively. The medication costs were reduced by 50% compared with the estimated costs for 10-day oseltamivir administration. The effectiveness of 5-day prophylactic oseltamivir was similar to or higher than that reported previously, indicating that this prophylaxis was effective. Moreover, 5-day post-exposure prophylactic oseltamivir is expected to reduce the prolongation of hospital stay and influenza outbreaks and thus contribute to hospital management.

BACKGROUND:
Glyphosate and its salt formulations are nonselective herbicides that have been extensively used worldwide, both for residential and agricultural purposes. The possible carcinogenicity and teratogenicity of glyphosate remain to be elucidated. We developed a sensitive and high-throughput analytical method for urinary glyphosate using liquid chromatography-tandem mass spectrometry with the aim of contributing to glyphosate exposure assessment in epidemiological studies.
METHODS:
After urine dilution (creatinine matching dilution to 0.05 g creatinine/L), glyphosate was extracted using two types of solid phase extraction columns (SCX and NH2) with automated sample preparation instruments. The eluate was dried and dissolved in the mobile phase, followed by liquid chromatography-tandem mass spectrometry analysis. The optimized method was applied to urine samples obtained from 54 Japanese adults and children.
RESULTS:
The results from the validation study demonstrated good recoveries (91.0-99.6%), within- and between-run precisions (< 15%), low detection limits (0.1 μg/L), and lower limit of quantification (0.3 μg/L). The detection frequency and median concentration of the urinary glyphosate in Japanese subjects were 59% and 0.25 μg/L (0.34 μg/g creatinine).
CONCLUSIONS
Our reliable determination method was successful in measuring urinary glyphosate concentration. Moreover, this is the first biomonitoring report of urinary glyphosate levels in the Japanese general population.

Introduction: The diagnosis of cancer-related neuropathic pain is often difficult for non-pain medicine specialists. We examined whether a Japanese version of a neuropathic pain screening questionnaire (Japan-Q), which was developed for chronic pain, is appropriate for screening cancer-related neuropathic pain. Methods: Our palliative care team screened 104 patients from May 2014 to December 2015 and compared total points of the Japan-Q with diagnosis of the type of cancer pain by specialized pain clinicians. Validity was evaluated using a receiver operating characteristic (ROC) curve. Results: The area under the ROC curve in terms of the total score, sensitivity, and specificity for the Japan Q was 0.82, which indicated a moderate level of diagnostic accuracy. A cut-off value of 3 points was shown to be best (sensitivity: 79%, specificity: 82%). When a cut-off value of 9 points was used as the diagnostic criterion for neuropathic pain, there was greatly reduced sensitivity (sensitivity: 40%, specificity: 97%). Conclusion: Although the Japan-Q shows moderate diagnostic accuracy related to cancer pain, the cut-off value for this tool is lower than that for chronic pain. Cancer-related neuropathic pain should be suspected with a total score of 3 or more in the Japan-Q.

We monitored the glucose levels of 3 patients who had undergone total gastrectomy without hypoglycemic symptoms using the Free Style Libre Pro®, a continuous glucose monitoring system, and assessed fluctuations. Mean patient age was 75±3 years and all were men. The highest and lowest sensor glucose (SG) values were 337±54 mg/dL and 44±8 mg/dL, respectively. In 2 of the 3 patients, the lowest SG value was 40 mg/dL, which was the lower limit of detection. After administration of alpha-glucosidase inhibitors, all patients showed improvement in the highest and lowest SG values, and the proportion of time when the SG value was 180 mg/dL or above decreased. The proportion of time when the SG value was less than 70 mg/dL increased in 2 of the 3 patients. However, mean SG values during the same time periods were higher than the pretreatment values, and the proportion of time when the value was less than 60 mg/dL decreased. Consensus error grid analysis performed using blood glucose levels from selfmonitored measurements and meal tolerance tests taken during continuous glucose monitoring versus SG values revealed that all data pairs were within the clinically acceptable regions (zones A and B).

BACKGROUND/AIMS: In distal malignant biliary obstruction, an antireflux metal stent (ARMS) with a funnel-shaped valve is effective as a reintervention for metal stent occlusion caused by reflux. This study sought to evaluate the feasibility of this ARMS as a first-line metal stent. METHODS: Patients with nonresectable distal malignant biliary obstruction were identified between April and December 2014 at three Japanese tertiary centers. We retrospectively evaluated recurrent biliary obstruction and adverse events after ARMS placement. RESULTS: In total, 20 consecutive patients were included. The most common cause of biliary obstruction was pancreatic cancer (75%). Overall, recurrent biliary obstruction was observed in seven patients (35%), with a median time to recurrent biliary obstruction of 246 days (range, 11 to 246 days). Stent occlusion occurred in five patients (25%), the causes of which were sludge and food impaction in three and two patients, respectively. Stent migration occurred in two patients (10%). The rate of adverse events associated with ARMS was 25%: pancreatitis occurred in three patients, cholecystitis in one and liver abscess in one. No patients experienced non-occlusion cholangitis. CONCLUSIONS: The ARMS as a first-line biliary drainage procedure was feasible. Because the ARMS did not fully prevent stent dysfunction due to reflux, further investigation is warranted.

A patient, an adultJapanese traveler who had just returned from Thailand, had developed denguehemorrhagic fever (DHF). A primary infection of dengue virus (DENV) wasconfirmed, in particular, DENV serotype 2 (DENV-2) via the detection of the virusgenome, a significant increase in its specific neutralizing antibody and the isolationof DENV-2. DHF is often observed following a secondary infection from another serotypeof dengue virus, particularly in children, but this case was a primaryinfection of DENV. Japan is a non-endemic country of dengue disease. Instead,only Japanese encephalitis (JE) is known to be an endemic flavivirus family. Inthis study, IgG antibody against Japanese encephalitis virus (JEV) was detected.JEV belongs to the family of dengue virus and prevails in Japan, particularly inKyushu. Among many risk factors for the occurrence of DHF, a plausiblecandidate could be a cross-reactive antibody-dependent enhancement (ADE)mechanism by JEV antibody. This indicates that most Japanese travelers, wholive in non-endemic areas of dengue, particularly in Kyushu, should payattention to the occurrence of DHF.

An adult Japanese man who had just returned from Thailand developed dengue hemorrhagic fever (DHF). A primary infection of dengue virus (DENV) was confirmed, specifically DENV serotype 2 (DENV-2), on the basis of the detection of the virus genome, a significant increase in the neutralizing antibody and the isolation of DENV-2. DHF is often observed following a secondary infection from another serotype of dengue virus, particularly in children, but this case was a primary infection of DENV. Japan is a non-endemic country for dengue disease. In fact, only Japanese encephalitis (JE) is known to be a member of the endemic flavivirus family. In this study, IgG antibody against Japanese encephalitis virus (JEV) was detected. JEV belongs to the family of dengue virus and prevails in Japan, particularly Kyushu. Among many risk factors for the occurrence of DHF, a plausible candidate could be a cross-reactive antibody-dependent enhancement (ADE) mechanism caused by JEV antibody. This indicates that most Japanese travelers who living in dengue non-endemic areas, particularly Kyushu, should be aware of the occurrence of DHF.

In the present study, we investigate the expression profile of the epidermal growth factor receptor family, which comprises EGFR/ErbB1, HER2/ErbB2, HER3/ErbB3 and HER4/ErbB4 in oral leukoplakia (LP). The expression of four epidermal growth factor receptor (EGFR) family genes and their ligands were measured in LP tissues from 14 patients and compared with levels in 10 patients with oral lichen planus (OLP) and normal oral mucosa (NOM) from 14 healthy donors by real-time polymerase chain reaction (PCR) and immunohistochemistry. Synchronous mRNA coexpression of ErbB1, ErbB2, ErbB3 and ErbB4 was detected in LP lesions. Out of the receptors, only ErbB4 mRNA and protein was more highly expressed in LP compared with NOM tissues. These were strongly expressed by epithelial keratinocytes in LP lesions, as shown by immunohistochemistry. Regarding the ligands, the mRNA of Neuregulin2 and 4 were more highly expressed in OLP compared with NOM tissues. Therefore, enhanced ErbB4 on the keratinocytes and synchronous modulation of EGFR family genes may contribute to the pathogenesis and carcinogenesis of LP.

We experienced the coronary artery bypass grafting (CABG) with essential thrombocythemia (ET). A case is a man of 73 years old. As for him, 3 vessel disease including left main trunk was recognized on coronary angiography, and it was planned CABG. However, we recognized blood cell aberration in blood examination, and it was diagnosed as ET. ET is classed as a chronic myeloproliferative disorder. It has two opposite tendencies, a bleeding tendency and thrombus tendency. Ischemic heart disease to merge ET is acute myocardial infarction by thrombus in case of most, and there are a few cases to need blood circulation reconstruction of coronary artery for angina pectoris. Perioperative hemorrhage and postoperative graft closure become a problem in CABG with ET. With the hydroxycarbamide which is DNA synthesis inhibitor of a platelet count, a function controlled it, and enforced CABG. He doesn't have any cardiac events and complications due to ET for 7 years post CABG. We report this case with a review of the literature.
