Abstract
To assess the risk of major birth defects after first-trimester exposure to carbocisteine and ambroxol during pregnancy, we conducted a prospective cohort study using counseling data for drug use during pregnancy provided by the Japan Drug Information Institute in Pregnancy and Toranomon Hospital. Counseling information, including drug usage and participants' demographic information, was collected between April 1988 and December 2017. Pregnancy outcome data, including major birth defects, were obtained using a questionnaire administered 1 month after delivery. The risks of major birth defects after first-trimester exposure to carbocisteine (n = 588) and ambroxol (n = 341) were compared with those of nonteratogenic drug use during the first trimester (n = 1525). The adjusted odds ratio (aORs) for major birth defects was calculated using a multiple logistic regression analysis adjusted for confounders. The incidence of major birth defects was 1.2% (7/588) and 2.1% (7/341) in the carbocisteine and ambroxol groups, respectively, which was comparable to the control group (26/1525, 1.7%). Results of multiple logistic regression demonstrated similar nonsignificant risks for both carbocisteine (aOR: 0.66, 95% confidence interval [CI]: 0.40-1.1, p = 0.11) and ambroxol (aOR: 1.1, 95% CI: 0.18-7.2, p = 0.88). No specific major birth defects were reported in the carbocisteine or ambroxol groups. This study demonstrated that carbocisteine and ambroxol exposure during the first trimester was not associated with an increased risk of major birth defects. These results could help in counseling for the use of these drugs during pregnancy and further alleviate anxiety in patients.

Abstract
BACKGROUND Although social interaction and social support during the "new normal" due to coronavirus disease 2019 (COVID-19) may be related to presenteeism, the effect between these factors has not been clear for Japanese workers. The aim of this study was to describe the presenteeism of Japanese workers with reference to social interaction and social support following the lifestyle changes due to COVID-19 and to assess whether social interaction and social support affected their presenteeism. METHODS The data were obtained from internet panel surveys from October 2020. Descriptive statistics were calculated, and multiple linear regression was conducted using the data from the first, fourth and fifth surveys, which were conducted during October to November 2020, July to August 2021, and September to October 2021, respectively. To measure presenteeism, questions from "absenteeism and presenteeism questions of the World Health Organization's Heath and Work Performance Questionnaire", short version in Japanese was utilized. Multiple linear regressions were conducted to investigate the effects of social interaction and social support-related factors on presenteeism. RESULTS A total of 3,407 participants were included in the analysis. The mean score of absolute presenteeism from the fifth survey was 58.07 (SD = 19.71). More time spent talking with family, a larger number of social supporters and a higher satisfaction level for social support were associated with a higher absolute presenteeism score. CONCLUSIONS Our results suggested that social support reduced the presenteeism of the Japanese workers during the "new normal" due to the COVID-19 pandemic. Social interaction with family also relieved presenteeism.

Abstract
OBJECTIVES To assess the usefulness of case reports as sources for research on diagnostic errors in uncommon diseases and atypical presentations. CONTENT We reviewed 563 case reports of diagnostic error. The commonality of the final diagnoses was classified based on the description in the articles, Orphanet, or epidemiological data on available references; the typicality of presentation was classified based on the description in the articles and the judgment of the physician researchers. Diagnosis Error Evaluation and Research (DEER), Reliable Diagnosis Challenges (RDC), and Generic Diagnostic Pitfalls (GDP) taxonomies were used to assess the factors contributing to diagnostic errors. SUMMARY AND OUTLOOK Excluding three cases in that commonality could not be classified, 560 cases were classified into four categories: typical presentations of common diseases (60, 10.7 %), atypical presentations of common diseases (35, 6.2 %), typical presentations of uncommon diseases (276, 49.3 %), and atypical presentations of uncommon diseases (189, 33.8 %). The most important DEER taxonomy was "Failure/delay in considering the diagnosis" among the four categories, whereas the most important RDC and GDP taxonomies varied with the categories. Case reports can be a useful data source for research on the diagnostic errors of uncommon diseases with or without atypical presentations.

Abstract
BACKGROUND An increased focus on quality and patient safety has led to the evolution of hospitalists. The number of hospitalists covering ward and outpatient care is on the rise in Japan. However, it is unclear what roles hospital workers themselves consider important in their practice. Therefore, this study investigated what hospitalists and non-hospitalist generalists in Japan consider important for the practice of their specialty. METHODS This was an observational study that included Japanese hospitalists (1) currently working in a general medicine (GM) or general internal medicine department and (2) working at a hospital. Using originally developed questionnaire items, we surveyed the items important to hospitalists and non-hospitalist generalists. RESULTS There were 971 participants (733 hospitalists, 238 non-hospitalist) in the study. The response rate was 26.1%. Both hospitalists and non-hospitalists ranked evidence-based medicine as the most important for their practice. In addition, hospitalists ranked diagnostic reasoning and inpatient medical management as the second and third most important roles for their practice, while non-hospitalists ranked inpatient medical management and elderly care as second and third. CONCLUSIONS This is the first study investigating the roles Japanese hospitalists consider important and comparing those to that of non-hospitalist generalists. Many of the items that hospitalists considered important were those that hospitalists in Japan are working on within and outside academic societies. We found that diagnostic medicine and quality and safety are areas that are likely to see further evolution as hospitalists specifically emphasized on them. In the future, we expect to see suggestions and research for further enhancing the items that hospital workers value and emphasise upon.

Abstract
BACKGROUND The association between anti-dementia drugs and arrhythmia is uncertain. In addition, the effects of certain drug combinations are not yet well known. OBJECTIVE We investigated the association between anti-dementia drugs and arrhythmia. Furthermore, we investigated the effects of anti-dementia drugs both alone and in combination on the likelihood of arrhythmia in patients with dementia. METHODS We examined the Japanese Adverse Drug Event Report database (JADER) from April 2004 to May 2022 for dementia drug users aged ≥ 60 years. We calculated the unadjusted reported odds ratio (ROR) and adjusted ROR for confounding factors. Furthermore, we examined the association of various combinations of anti-dementia drugs with the development of arrhythmias. RESULTS There were 6718 arrhythmia cases identified out of 333,702 reported cases. The unadjusted ROR results were as follows: donepezil alone (ROR 4.39, 95% confidence interval [CI] 3.89-4.95), rivastigmine alone (2.10, 1.53-2.87), galantamine alone (3.87, 3.04-4.94), memantine alone (2.25, 1.59-3.20), and combination of choline esterase inhibitor and memantine (2.56, 1.84-3.57). In a multivariate analysis, the RORs remained significant. CONCLUSIONS Regardless of whether anti-dementia drugs were used alone or in combination, attention should be paid to the occurrence of arrhythmias.

Abstract
BACKGROUND A serious shortage of cefazolin (CEZ) occurred in Japan in 2019. We compared the impact of the CEZ shortage on the selection of parenteral antibiotics at affected and non-affected hospitals. METHODS The data were extracted from a nationwide Japanese administrative database and included all hospitalized cases between April 2016 and December 2020. We defined 'hospitals with shortage' as those hospitals with a statistically significant decrease in the use of CEZ during the supply disruption period compared to the same months of the previous year; other hospitals as 'hospitals without shortage'. We determined the proportion of each selected parenteral antibiotic use to the sum of all selected antibiotic use in the two groups of hospitals during the supply disruption period and during the same months of the previous year. A controlled interrupted time series (CITS) analysis was conducted to estimate the impact of the CEZ shortage on each antibiotic use and the cost of all parenteral antibiotics per patient day in hospitals with shortage as compared to those without shortage. RESULTS In the hospitals with shortage, the proportion of CEZ use to the sum of all selected antibiotics decreased (23.5-11.1%). The decrease in CEZ use was mainly offset by the use of ceftriaxone, ceftriaxone, and ampicillin/sulbactam. The CITS analysis showed a statistically significant increase in the use of broader-spectrum beta-lactams and clindamycin during the supply disruption period (flomoxef up 58.1%, cefotiam up 63.1%, cefmetazole up 14.5%, ceftriaxone up 13.9%, and clindamycin up 20.1%). The analysis showed no statistically significant change in the cost of all parenteral antibiotics per patient day. CONCLUSIONS During the CEZ supply disruption, there was a statistically significant increase in the use of broader-spectrum beta-lactams and clindamycin in hospitals with shortage compared with those without shortage.

Abstract
Samples of the carbonaceous asteroid Ryugu were brought to Earth by the Hayabusa2 spacecraft. We analyzed 17 Ryugu samples measuring 1 to 8 millimeters. Carbon dioxide-bearing water inclusions are present within a pyrrhotite crystal, indicating that Ryugu's parent asteroid formed in the outer Solar System. The samples contain low abundances of materials that formed at high temperatures, such as chondrules and calcium- and aluminum-rich inclusions. The samples are rich in phyllosilicates and carbonates, which formed through aqueous alteration reactions at low temperature, high pH, and water/rock ratios of <1 (by mass). Less altered fragments contain olivine, pyroxene, amorphous silicates, calcite, and phosphide. Numerical simulations, based on the mineralogical and physical properties of the samples, indicate that Ryugu's parent body formed ~2 million years after the beginning of Solar System formation.

Abstract
We investigated the relationship between multidrug administration and the characteristics, pathophysiology, and drug class in outpatients with hemodialysis. A retrospective cross-sectional study was conducted at Saitama Medical University Hospital in October 2018. Multidrug administration was defined as receiving either more than six drugs or more than the median number of drugs. The drugs used were represented by their anatomical classification codes in the Anatomical Therapeutic Chemistry Classification System (ATC classification). A latent class analysis (LCA) was used to identify clusters at risk of receiving multiple medications. A stepwise logistic regression analysis was performed to select ATC classifications prone to being involved in multidrug administration. As of October 2018, 98 outpatients with hemodialysis were enrolled in the study. In the LCA, when diabetes was the main primary disease, oral hypoglycemic agents available to dialysis patients were limited, but the number of drugs administered was large. Old age, poor nourishment, a long history of dialysis, and chronic nephritis were associated with multidrug administration among nondiabetic patients. In the second level of the ATC classification, the drugs frequently used were coded A02 (drugs for acid-related disorders), A07 (antidiarrheal agents, intestinal anti-inflammatory/anti-infective agents), B01 (antithrombotic agents), and N05 (psycholeptics). The prescribing patterns for either diabetic patients or nondiabetic elderly patients were identified in outpatients with hemodialysis taking multiple medications, and drugs for acid-related disorders, antidiarrheal agents, intestinal anti-inflammatory/anti-infective agents, antithrombotic agents, and psycholeptics are frequently used in those patients.

Abstract
BACKGROUND AND AIMS The purpose of this study was to investigate differences in the frequency of renally inappropriate medications (RIMs) in outpatient and inpatient among three institutions. METHODS We collected prescription and renal function data for patients over 65 years of age from the drug department system. We selected 50 kinds of the most frequently used medicines which require dose adjustment according to a patient's renal function. RESULTS Outpatient RIM was seen in 611 cases (6.17%), and inpatient prescription RIM was seen in 317 cases (5.29%), showing a significant difference between the groups (odds ratio [OR] 1.18, 95% confidence interval [CI] 1.02-1.35). However, in a multivariate analysis, when the renal function was included, that difference between outpatients and inpatients became insignificant (OR 1.16, 95% CI 0.98-1.37). The distribution of prescription with or without RIM in outpatient and inpatient settings depended on the CKD stage. Outpatients with a better CKD stage (stage 1-3) had a higher rate of RIM than inpatients, while patients with a worse CKD stage (stage 4 or 5) had a higher rate of RIM than outpatients. CONCLUSION The rate of RIM in outpatients tends to be high, and attention should be paid to RIM in inpatients with a severe CKD stage.

Abstract
Demand is increasing for general medicine services in Japan, a super-aged society. The new medical specialty system introduced in 2019 obligates physicians to obtain a qualified specialty from among 19 basic specialty fields, including general medicine, before obtaining more advanced qualified subspecialties. The role of the department of general medicine in Japan varies in each hospital. Remuneration for medical services obtained by general medicine departments that mainly provide outpatient care is relatively low, making it difficult to fill positions in this department within a hospital. We conducted a narrative review and discussed ways to increase the status of hospital general medicine departments that mainly provide outpatient care. We consider the following four points to be important: improvement of diagnostic capabilities in the outpatient setting; playing a central role in education for medical students and residents; active involvement with patients who have diagnostic difficulties or social problems; and branding and promotion of the general medicine department. We envision that adopting an active approach to these points will increase the status of general medicine departments that mainly provide outpatient care within the hospital, allowing such newly established departments to start easily in Japanese hospitals in the future.

Abstract
Background In Japan, many older people hope to receive end‐of‐life care at home. In such situations, team‐based home medical care with the support of on‐call physicians is needed. However, to date, necessary competencies for the on‐call physicians have yet to be clarified. We aim to reveal the competencies for on‐call physicians in home medical care settings. Method This was a qualitative study of semi‐structured interviews concerning competencies for on‐call physicians in home medical care. We evaluated digitally recorded interviews with eight home care professionals in seven home care facilities (three clinics, one hospital, and three nursing agencies) in A City, Japan. The transcribed data were analyzed by three researchers using thematic analysis. Results The competencies for on‐call physicians were divided into the following six categories: clinical skills for frequent complaints, collecting patients' information in advance, understanding purposes of home care, understanding general roles of home care health professionals, thoughtfulness toward patients' families, and an attitude of humility. Conclusion These competencies were classified into disease‐specific and interpersonal (collaborative) skills in home medical care. The competencies revealed by the study could contribute to the development of effective learning and preparation for on‐call physicians who support home medical care.

Abstract
Purpose To identify the current ambiguous status of general medicine (GM) and assess current problems and weaknesses for further development of GM. Patients and Methods This study adopted an observational design. GM practitioners were selected from the mailing lists of two primary professional associations for Japanese GM doctors. We included physicians currently working in a GM department, those self-described as GM doctors, and those board-certified in family medicine or general internal medicine. Respondents replied to survey questions about their sociodemographic data, job descriptions, and the requisite skills for practice. GM doctors’ job description and required skills were categorized into “clinical,” “management,” “education,” and “research.” Participants (n = 971) were compared based on job descriptions and important skills in each category by facility type, size, and position. Results “Clinical” was indicated as the most important category for both job description and important skills, followed by “management,” “education,” and “research.” For job description details, “follow-up outpatient” (35.6%) ranked first for “clinical,” and “resident education” (57.3%) ranked first for “education.” By facility type and size, job description and important skills decreased for clinical and management categories as facility sizes increased; the opposite was true for “education.” “Research” was generally rated low. By position, no significant difference was found in effort or importance given to research. Conclusion This study is the first survey on GM physicians across Japan. The results show that while Japanese GM physicians focus on and place importance on clinical practice, they are less involved in research and do not consider research skills to be important. The challenge for the future development of GM lies in research.

Abstract
Background The pandemic of the coronavirus disease 2019 (COVID-19) has affected health care systems globally. The aim of our study is to assess the impact of the COVID-19 pandemic on the number of hospital admissions for ischemic stroke by severity in Japan. Methods We analysed administrative (Diagnosis Procedure Combination—DPC) data for cases of inpatients aged 18 years and older who were diagnosed with ischemic stroke and admitted during the period April 1 2018 to June 27 2020. Levels of change of the weekly number of inpatient cases with ischemic stroke diagnosis after the declaration of state of emergency were assessed using interrupted time-series (ITS) analysis. The numbers of patients with various characteristics and treatment approaches were compared. We also performed an ITS analysis for each group (“independent” or “dependent”) divided based on components of activities of daily living (ADL) and level of consciousness at hospital admission. Results A total of 170,294 cases in 567 hospitals were included. The ITS analysis showed a significant decrease in the weekly number of ischemic stroke cases hospitalized (estimated decrease: −156 cases; 95% confidence interval (CI): −209 to −104), which corresponds to −10.4% (95% CI: −13.6 to −7.1). The proportion of decline in the independent group (−21.3%; 95% CI: −26.0 to −16.2) was larger than that in the dependent group (−8.6%; 95% CI: −11.7 to −5.4). Conclusions Our results show a marked reduction in hospital admissions due to ischemic stroke after the declaration of the state of emergency for the COVID-19 pandemic. The independent cases were affected more in proportion than dependent cases.

Abstract
Background Oral mucositis (OM) is an unpleasant adverse event in patients receiving chemotherapy. A prospective feasibility study showed that elemental diet (ED), an oral supplement that does not require digestion, may prevent OM. Based on this, we established a central review system for oral cavity assessment by dental oncology specialists blinded to background data. We used this system to elucidate the preventive effect of an ED against OM in patients with esophageal cancer receiving docetaxel, cisplatin, and 5-fluorouracil (DCF) therapy. Patients and methods In this phase III, multicenter, parallel-group, controlled trial, patients consuming a normal diet orally were randomly assigned (1 : 1) to receive two cycles of DCF with (group A) or without (group B) an ED (Elental® 160 g/day). We assessed the incidence of grade ≥2 OM evaluated by two reviewers, changes in body weight, prealbumin, C-reactive protein, and DCF completion rate based on ED compliance. Results Of the 117 patients randomly assigned to treatment, four failed to start treatment and were excluded from the primary analysis; thus, groups A and B comprised 55 and 58 patients, respectively. There were no significant differences in background characteristics. Grade ≥2 OM was observed in eight (15%) and 20 (34%) patients in groups A and B, respectively (P = 0.0141). Changes in body weight and prealbumin during the two DCF cycles were significantly higher in group A than B (P = 0.0022 and 0.0203, respectively). During the first cycle, changes in C-reactive protein were significantly lower in group A than B (P = 0.0338). In group A (receiving ED), the DCF completion rate was 100% in patients with 100% ED compliance and 70% in patients failing ED completion (P = 0.0046). Conclusions The study findings demonstrate that an ED can prevent OM in patients with esophageal cancer receiving chemotherapy. Patients receiving docetaxel, cisplatin, and 5-fluorouracil (DCF) chemotherapy commonly develop oral mucositis (OM). An elemental diet (ED) was able to prevent OM in patients with esophageal cancer receiving DCF. Grade ≥2 OM was observed in 15% of patients receiving the ED versus 34% of those not receiving the ED (P = 0.0141). Body weight was maintained in the ED group, and hematologic toxicities were lower, compared with the non-ED group. The DCF completion rate significantly correlated with ED compliance (P = 0.0046).

Abstract
OBJECTIVE The coronavirus disease 2019 (COVID-19) pandemic has affected all healthcare systems. This study aimed to assess the impact of the COVID-19 pandemic on the number and severity of cases of community-acquired pneumonia (CAP) in Japan. METHODS Using claims data from the Quality Indicator/Improvement Project (QIP) database, urgent cases of inpatients for CAP from 01 August 2018 to 30 July 2020 were included. The monthly ratios of inpatient cases were compared from August 2018 to July 2019 and August 2019 to July 2020 as a year-over-year comparison. These ratios were also compared according to the "A-DROP" severity score, and an interrupted time series (ITS) analysis was performed to evaluate the impact of the COVID-19 pandemic on the monthly number of inpatient cases. RESULTS This study included a total of 67,900 inpatient cases for CAP in 262 hospitals. During the COVID-19 pandemic (defined as the period between March and July 2020) the number of inpatient cases for CAP drastically decreased compared with the same period in the previous year (-48.1%), despite a temporary reduction in the number of other urgent admissions. The number of inpatient cases decreased according to the severity of pneumonia. Milder cases showed a greater decrease in the year-over-year ratio than severe ones: mild -55.2%, moderate -45.8%, severe -39.4%, and extremely severe -33.2%. The ITS analysis showed that the COVID-19 pandemic significantly reduced the monthly number of inpatient cases for CAP (estimated decrease: -1233 cases; 95% CI -521 to -1955). CONCLUSIONS This study showed a significant reduction in the number of inpatient cases for CAP during the COVID-19 pandemic in Japan. The milder cases showed a greater decrease in the year-over-year ratio of the number of inpatient cases.

Abstract
BACKGROUND Research engagement contributes to the improvement of patient care. A systematic review is a suitable first scholarly activity because it entails summarization of publicly available data and usually requires neither rigorous ethical review nor research funding. METHODS This study aimed to develop a model workshop for healthcare staff to acquire skills in creating systematic review protocols based on their own clinical questions at teaching hospitals. We used an action research method to create a model workshop at four hospitals in Japan from April 2015 to March 2017. To improve the program, we solicited reflections using participant questionnaires for each lecture and examined the quality of homework submitted by participants after each lecture. We administered a revised final version of the workshop at five hospitals from April 2016 to March 2017. We evaluated the participants' scholarly productivity related to these workshops. The observation period was a minimum of 2 years following the workshops. RESULTS Most participants had never developed a formal clinical research protocol and voluntarily participated in the workshop. The action research was developed and implemented at nine teaching hospitals in Japan, including one university hospital. The study developed a model nine-step workshop curriculum: 1) Research question development, 2) Search strategy development, 3) Search strategy brush-up, 4) Exclusion and inclusion criteria development, 5) Risk of bias assessment planning, 6) Meta-analysis planning, 7) Subgroup and sensitivity analysis planning, 8) Planning the presentation of results, and 9) Presentation protocols. A total of 233 participants, including medical doctors and other health professionals, produced 414 research questions. Seventy-nine participants (34%) completed the workshop, and 47 review teams accomplished systematic review protocols. The participants published 13 peer-reviewed articles as a result of the workshop. CONCLUSIONS We developed a structured scholarly productive model workshop for healthcare staff working at hospitals. We found healthcare staff with clinical subspecialties were able to develop an unexpectedly high number of research questions through this workshop. Medical teachers at hospitals with prior systematic review experience could teach how to develop systematic review protocols using this model. Further research is needed to increase the academic productivity of such workshops. TRIAL REGISTRATION UMIN (https://www.umin.ac.jp/ctr/), UMIN000017107 (4/15/2015), UMIN000025580 (1/10/2017).

Abstract
Background Hepatocellular carcinoma (HCC) with tumour thrombus (TT) in the inferior vena cava (IVC) or right atrium (RA) is a rare advanced disease state with a poor prognosis. The aim of this study was to examine survival after surgical resection. Methods Patients with HCC and TT of either the IVC or RA, who underwent liver resection between February 1997 and July 2017, were included. Their short‐ and long‐term outcomes and surgical details were analysed retrospectively. Results Thirty‐seven patients were included; 16 patients had TT in the IVC below the diaphragm, eight had TT in the IVC above the diaphragm, and 13 had TT entering the RA. Twelve patients had advanced portal vein TT (portal vein invasion (Vp) greater than Vp3 and Vp4), ten had bilobar disease, and 12 had extrahepatic disease. There were no in‐hospital deaths, although two patients died within 90 days. Median survival did not differ between patients who had resection with curative intent (18·7 months) and those with residual tumour in the lung only (20·7 months), but survival was poor for patients with residual tumour in the liver (8·3 months). Conclusion Liver resection with thrombectomy for advanced HCC with TT in the IVC or RA is safe and feasible, leading to moderate survival.

Abstract
Isoniazid preventative therapy is widely used for latent tuberculosis infection. Isoniazid is highly effective but has many adverse effects, including neuropsychiatric. We describe the case of an 80-year-old woman with mania. She had received isoniazid preventative therapy during steroid treatment for rheumatoid arthritis and organising pneumonia for the previous 5 months. Her mania resolved after discontinuation of isoniazid. Adverse effects of isoniazid should be considered even if a long time has elapsed since the start of administration. Physicians other than infectious disease and respiratory specialists also must be aware of the adverse effects of isoniazid preventative therapy.

OBJECTIVE To prevent functional decline in older inpatients, identification of high-risk patients is crucial. The aim of this study was to develop and validate a prediction model to assess the risk of functional decline in older medical inpatients. METHODS In this retrospective cohort study, patients ≥65 years admitted acutely to medical wards were included. The healthcare database of 246 acute care hospitals (n = 229,913) was used for derivation, and two acute care hospitals (n = 1767 and 5443, respectively) were used for validation. Data were collected using a national administrative claims and discharge database. Functional decline was defined as a decline of the Katz score at discharge compared with on admission. RESULTS About 6% of patients in the derivation cohort and 9% and 2% in each validation cohort developed functional decline. A model with 7 items, age, body mass index, living in a nursing home, ambulance use, need for assistance in walking, dementia, and bedsore, was developed. On internal validation, it demonstrated a c-statistic of 0.77 (95% confidence interval (CI) = 0.767-0.771) and good fit on the calibration plot. On external validation, the c-statistics were 0.79 (95% CI = 0.77-0.81) and 0.75 (95% CI = 0.73-0.77) for each cohort, respectively. Calibration plots showed good fit in one cohort and overestimation in the other one. CONCLUSIONS A prediction model for functional decline in older medical inpatients was derived and validated. It is expected that use of the model would lead to early identification of high-risk patients and introducing early intervention.

Abstract
An enzyme catalyzing the ammonia-lyase reaction for the conversion of d-erythro-3-hydroxyaspartate to oxaloacetate was purified from the cell-free extract of a soil-isolated bacterium Pseudomonas sp. N99. The enzyme exhibited ammonia-lyase activity toward l-threo-3-hydroxyaspartate and d-erythro-3-hydroxyaspartate, but not toward other 3-hydroxyaspartate isomers. The deduced amino acid sequence of the enzyme, which belongs to the serine/threonine dehydratase family, shows similarity to the sequence of l-threo-3-hydroxyaspartate ammonia-lyase (EC 4.3.1.16) from Pseudomonas sp. T62 (74%) and Saccharomyces cerevisiae (64%) and serine racemase from Schizosaccharomyces pombe (65%). These results suggest that the enzyme is similar to l-threo-3-hydroxyaspartate ammonia-lyase from Pseudomonas sp. T62, which does not act on d-erythro-3-hydroxyaspartate. We also then used the recombinant enzyme expressed in Escherichia coli to produce optically pure l-erythro-3-hydroxyaspartate and d-threo-3-hydroxyaspartate from the corresponding dl-racemic mixtures. The enzymatic resolution reported here is one of the simplest and the first enzymatic method that can be used for obtaining optically pure l-erythro-3-hydroxyaspartate.

Abstract
Falls prevention is important for older individuals to maintain healthy lifestyles and is an essential challenge in sustaining the socioeconomic structure of many advanced nations. Tripping has been recognized as the largest cause of falls and accordingly, understanding tripping-induced anterior balance loss is necessary in reducing the overall frequency of falls among older adults. Hazardous anterior balance loss due to tripping can be attributed to the mid-swing phase event, minimum foot clearance (MFC). The mechanism of tripping-induced anterior balance loss can be described as anterior movement of the center of mass (CoM) passing the frontal boundary of the supporting base between the swing and stance toes. The first aim of the current study was to establish a computational method for determining available response time (ART) to anterior balance loss due to tripping at MFC, in other words, the time taken for CoM to reach the anterior boundary and therefore, the time limit for balance recovery. Kinematic information of CoM and both toes in addition to simulated impact force due to tripping at MFC were used to estimate ART. The second aim was to apply correlation analysis to a range of gait parameters to identify the factors influencing ART. ART for balance loss in the forward direction due to tripping was on average. 0.11s for both the dominant and non-dominant limbs' simulated tripping at MFC. Correlation analysis revealed five factors at MFC that prolong ART including: 1) greater fore-aft distance from CoM to stance toe, 2) greater sideway distance from CoM to swing toe, 3) longer distance from CoM to the frontal boundary of the supporting base, 4) slower CoM forward velocity and 5) slower horizontal toe velocity. The established ART computation method can be utilized to examine the effects of ageing and various gait tasks on the likelihood of tripping-induced anterior balance loss and associated falls.

Abstract
Background: Pancreatic cancer has a poor prognosis because of its high refractoriness to chemotherapy and tumour recurrence, and these properties have been attributed to cancer stem cells (CSCs). MicroRNA (miRNA) regulates various molecular mechanisms of cancer progression associated with CSCs. This study aimed to identify the candidate miRNA and to characterise the clinical significance. Methods: We established gemcitabine-resistant Panc1 cells, and induced CSC-like properties through sphere formation. Candidate miRNAs were selected through microarray analysis. The overexpression and knockdown experiments were performed by evaluating the in vitro cell growth and in vivo tumourigenicity. The expression was studied in 24 pancreatic cancer samples after laser captured microdissection and by immunohistochemical staining. Results: The in vitro drug sensitivity of pancreatic cancer cells was altered according to the miR-1246 expression via CCNG2. In vivo, we found that miR-1246 could increase tumour-initiating potential and induced drug resistance. A high expression level of miR-1246 was correlated with a worse prognosis and CCNG2 expression was significantly lower in those patients. Conclusions: miR-1246 expression was associated with chemoresistance and CSC-like properties via CCNG2, and could predict worse prognosis in pancreatic cancer patients.
