Neoadjuvant chemotherapyeoadjuvant chemoradiotherapy (NAC/NACRT) can be performed in patients with pancreatic cancer to improve survival. We aimed to clarify the clinical outcomes of biliary drainage with a metal stent (MS) or a plastic stent (PS) during NAC/NACRT. Between October 2013 and April 2016, 96 patients with pancreatic cancer were registered for NAC/NACRT. Of these, 29 patients who underwent biliary drainage with MS or PS before NAC/NACRT and a subsequent pancreatoduodenectomy were retrospectively analyzed with regard to patient characteristics, preoperative recurrent biliary obstruction rate, NAC/NACRT delay or discontinuation rate, and operative characteristics. The median age of the patients was 67 years. NAC and NACRT were performed in 14 and 15 patients, respectively, and MS and PS were used in 17 and 12 patients, respectively. Recurrent biliary obstruction occurred in 6% and 83% of the patients in the MS and PS groups, respectively (p<0.001). NAC/NACRT delay was observed in 35% and 50% of the patients in the MS and PS groups, respectively (p=0.680). NAC/NACRT discontinuation was observed in 12% and 17% of the patients in the MS and PS groups, respectively (p=1.000). The operative time in the MS group tended to be longer than that in the PS group (625 minutes vs 497 minutes, p=0.051), and the operative blood loss volumes and postoperative adverse event rates were not different between the two groups. MS was better than PS from the viewpoint of preventing recurrent biliary obstruction, although MS was similar to PS with regards to perioperative outcomes.

Proteins usually associate with other molecules physically to execute their functions. Identifying these interactions is important for the functional analysis of proteins. Previously, we reported the parallel analysis of translated ORFs (PLATO) to couple ribosome display of full-length ORFs with affinity enrichment of mRNA/protein/ribosome complexes for the "bait" molecules, followed by the deep sequencing analysis of mRNA. However, the sample processing, from extraction of precipitated mRNA to generation of DNA libraries, includes numerous steps, which is tedious and may cause the loss of materials. Barcoded PLATO (PLATO-BC), an improved platform was further developed to test its application for protein interaction discovery. In this report, we tested the antisera-antigen interaction using serum samples from patients with inclusion body myositis (IBM). Tripartite motif containing 21 (TRIM21) was identified as a potentially new IBM autoantigen. We also expanded the application of PLATO-BC to identify protein interactions for JQ1, single ubiquitin peptide, and NS5 protein of Zika virus. From PLATO-BC analyses, we identified new protein interactions for these "bait" molecules. We demonstrate that Ewing sarcoma breakpoint region 1 (EWSR1) binds to JQ1 and their interactions may interrupt the EWSR1 association with acetylated histone H4. RIO kinase 3 (RIOK3), a newly identified ubiquitin-binding protein, is preferentially associated with K63-ubiquitin chain. We also find that Zika NS5 protein interacts with two previously unreported host proteins, par-3 family cell polarity regulator (PARD3) and chromosome 19 open reading frame 53 (C19orf53), whose attenuated expression benefits the replication of Zika virus. These results further demonstrate that PLATO-BC is capable of identifying novel protein interactions for various types of "bait" molecules.

BACKGROUND/AIMS: Although the risk of bleeding after endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) is low, the safety of EUS-FNA in patients prescribed antithrom-botic agents is unclear. Therefore, this study evaluated the incidence of bleeding after EUS-FNA in those patients. METHODS: Between September 2012 and September 2015, patients who were prescribed antithrombotic agents underwent EUS-FNA at 13 institutions in Japan were prospectively enrolled in the study. The antithrombotic agents were managed according to the guidelines of the Japanese Gastrointestinal Endoscopy Society. The rate of bleeding events, thromboembolic events and other complications within 2 weeks after EUS-FNA were analyzed. RESULTS: Of the 2,629 patients who underwent EUS-FNA during the study period, 85 (62 males; median age, 74 years) patients were included in this stduy. Two patients (2.4%; 95% confidence interval [CI], 0.6% to 8.3%) experienced bleeding events. One patient required surgical intervention for hemothorax 5 hours after EUS-FNA, and the other experienced melena 8 days after EUS-FNA and required red blood cell transfusions. No thromboembolic events occurred (0%; 95% CI, 0.0% to 4.4%). Three patients (3.5%; 95% CI, 1.2% to 10.0%) experienced peri-puncture abscess formation. CONCLUSIONS: The rate of bleeding after EUS-FNA in patients prescribed antithrombotic agents might be considerable.

Objective: Caffeine may cause dependence and sleep disturbance, and interact with psychotropic drugs.　Therefore, the caffeine intake of patients with mental disorders should be monitored.　However, in Japan, there is no report on the effects of caffeine in mental disease patients or on their caffeine intake.　Therefore, we conducted a questionnaire survey to clarify the perception of caffeine for psychiatric outpatients.Methods: We conducted an anonymous survey on caffeine recognition for outpatients at 8 medical institutions that advocate psychiatry.Results: We collected questionnaires from 180 people.　The knowledge of foods containing caffeine tended to be high in those who had a positive attitude toward caffeine.　More than 90% of those surveyed knew that coffee contains caffeine, but cocoa and jasmine tea were recognized by less than 25%.　Of those surveyed, 39.4% consumed caffeine‐containing beverages at night.　In addition, the rate of consumption of caffeine‐containing beverages tended to be higher at night because they had a positive attitude toward caffeine.Conclusion: The knowledge and intake situation of caffeine by patients with mental disorders differed depending on their interests and way of thinking about caffeine.　As caffeine intake may influence psychiatric treatment, correct knowledge regarding caffeine is important.

The purpose of educating patients with diabetes mellitus (DM) is to facilitate their understanding of the disease and treatment, as well as to motivate the patients to improve their lifestyle. We recently assessed whether the results of psychological tests to investigate the mental status of DM patients were useful in obtaining a better outcome of education. The subjects were 75 DM out patients who were receiving treatment at out hospital (age range : 15-85 years, mean age : 66 years). The psychological tests were performed during a diabetic seminar held on February 26, 2002, using the Center for Epidemiologic Studies Depression Scale (CES-D Scale) and the Coping Inventory for Stressful Situation (CISS).On the CES-D scales, 20 points or higher scores were marked by 16 patients (21.3%), indicating a strong tendency to depression among DM patients. Assessment by the CISS showed a higher score on the task-oriented coping scale (T scale) than on the other scales (p<0.05), suggesting that DM patients are well-oriented towards the continuation of treatment. The CES-D Scale score tended to be higher in patients with an uncontrolled HbA1C (≥8%) (p<0.05), suggesting that a persistent depressed status is associated with poor glycemic control. The results of these psychological tests appeared to be useful in working out a more effective educational program for DM patients.

Patients who underwent the bypass operation during 5 years from 1987 to 1992 in the 1st Department of Surgery, Hiroshima University School of Medicine, were divided into 2 groups; AIOD group (51 cases) had lesions in the aorta and iliac artery, and FPOD group (46 cases) had lesions in the femoral artery and popliteal artery. A comparative study of these two groups was made. There was no significant difference in age, sex, symptom severity, smoking history, serum cholesterol level, serum triglyceride level. The complication rate of peripheral lesions of the AIOD group was 24% and of the FPOD group was 57%. The cumulative patency rate for 5 years of the AIDO group was 100% and of the FPOD group was 61%. The AIOD group exhibited better patency. In addition to the lower complication rate of peripheral lesions, all the AIOD group had underwent reconstruction operation for peripheral lesions simultaneously. The run-off state of the peripheral region may thus possibly be related to patency.

Fifty-one cases which underwent surgery for arteriosclerosis obliterans in the aorta and iliac artery at the First Department of Surgery, Hiroshima University School of Medicine were divided into two groups. The EAB group (18 cases) underwent extra-anatomic bypass operation, and the AB group (33 cases) underwent anatomic bypass operation. A comparative study showed the mean age of the EAB group to be 10 years higher than that of the AB group, and the former group exhibited severer symptoms. Renal and pulmonary function declined in the EAB group, and the occurrence rate of complications such as cerebral infarction was also higher At operation, the following approaches were employed; long-term administration of PGE-1 before and after operation, operation with a better visual field under light general anesthesia, simultaneous reconstructive operation in peripheral lesions, artificial vessels of externally supported velour knitted Dacron. There was no case of obstruction in the past 5 years. Extra-anatomic bypass operation therefore provides as good postoperative patency as anatomic operation.

A 74-year-old man presented with swelling in both lower limbs and fatigue. Venography indicated nozzle-like stenosis of the inferior vena cava that appeared during the inspiratory phase but disappeared during the expiratory phase. A large pressure gradient between the upper and lower portion of the stenosis was observed during the expiratory phase. Stenosis during the inspiratory phase was relieved by percutaneous transluminal angioplasty, and symptoms and signs disappeared. Although stenosis occurred only during the inspiratory phase, our patient exhibited symptoms characteristic of Budd-Chiari syndrome. We believe that this patient originally had stenosis of the diaphragmatic portion of the inferior vena cava, and that his symptoms derived from the formation of a parietal thrombus.

In Japan there are many people who are intolerant to alcohol. Known as flushers, they do not genetically have low Km acetaldehyde dehydrogenase (AlDH₂). Flushers are judged easily and accurately by the alcohol patch test. An ethanol patch test carried out on agricultural and fishing populations in Japan showed that approx. 40% were deficient in AlDH₂. A questionnaire survey of the drinking behavior of many people showed significant differences between the normal AlDH₂ and AlDH₂-deficient groups. The normal group drinks positively and actively, while the deficient group drinks negatively and passively. As a result, there were significant differences in subjective and objective symptoms that result from drinking between the two groups: More frequent hangovers, abnormal physical conditions and higher KAST scores were seen in the normal group, and health examination showed higher values in liver function tests, including γ-GTP, and higher levels of blood pressure, HDL-cholesterol (HDL-C), etc., in the normal AlDH₂group.
It may be very useful for prevention of alcohol-related health disorders to help Mongoloid peoples, such as the Japanese, recognize whether their AlDH₂ is normal or deficient, which is as determined by the ethanol patch test.
