Candidatus Bartonella merieuxii, a potential new zoonotic Bartonella species in canids from Iraq.

Bartonellae are emerging vector-borne pathogens infecting erythrocytes and endothelial cells of various domestic and wild mammals. Blood samples were collected from domestic and wild canids in Iraq under the United States Army zoonotic disease surveillance program. Serology was performed using an indirect immunofluorescent antibody test for B. henselae, B. clarridgeiae, B. vinsonii subsp. berkhoffii and B. bovis. Overall seroprevalence was 47.4% in dogs (n = 97), 40.4% in jackals (n = 57) and 12.8% in red foxes (n = 39). Bartonella species DNA was amplified from whole blood and representative strains were sequenced. DNA of a new Bartonella species similar to but distinct from B. bovis, was amplified from 37.1% of the dogs and 12.3% of the jackals. B. vinsonii subsp. berkhoffii was also amplified from one jackal and no Bartonella DNA was amplified from foxes. Adjusting for age, the odds of dogs being Bartonella PCR positive were 11.94 times higher than for wild canids (95% CI: 4.55-31.35), suggesting their role as reservoir for this new Bartonella species. This study reports on the prevalence of Bartonella species in domestic and wild canids of Iraq and provides the first detection of Bartonella in jackals. We propose Candidatus Bartonella merieuxii for this new Bartonella species. Most of the Bartonella species identified in sick dogs are also pathogenic for humans. Therefore, seroprevalence in Iraqi dog owners and bacteremia in Iraqi people with unexplained fever or culture negative endocarditis requires further investigation as well as in United States military personnel who were stationed in Iraq. Finally, it will also be essential to test any dog brought back from Iraq to the USA for presence of Bartonella bacteremia to prevent any accidental introduction of a new Bartonella species to the New World

Initial In-Orbit Operation Result of Microsatellite HIBARI: Attitude Control by Driving Solar Array Paddles

We have developed a 50kg class microsatellite HIBARI . The mission of this satellite is to demonstrate a novel attitude control method for microsatellites which is called “Variable Shape Attitude Control (VSAC).” VSAC is a method using anti-torque by driving variable shape structures. HIBARI has four drivable solar array paddles, and will demonstrate VSAC. The development of HIBARI began in 2019, and it was injected into orbit in November 2021 under the Innovative Satellite Technology Demonstration Program led by JAXA. Currently, HIBARI has completed its critical phase and paddle deployment phase, and is conducting paddle drive experiments in orbit. In paddle drive experiments, the paddles are driven according to the command values, and the accompanying attitude change is confirmed. These results indicate that the satellite can generate angular velocities of 4 deg/s or more and achieve the target agile maneuver of 30deg in 10seconds, which is comparable to that of CMG for microsatellite

地域で生活している５５歳以上の方の慢性疾患，年齢の捉え方，睡眠の質，健康関連QOL，日常生活行動との関係性

Japan’s aging population rate is increasing and healthy life expectancy has decreases by 10 years shorter than average life expectancy. The aim of this study is to determine the relationship among chronic disease, sleep quality, health-related quality of life (HRQOL), and activities of daily living in people over 55 years old who live in the community. Subjects were 161 persons aged 57 to 90 years who were treated with chronic disease in the outpatient department of the A hospital. Exclusion criteria included patients with dementia, cancer and severe heart disease. The survey evaluation questionnaires included the Pittsburgh Sleep Quality Index (PSQI), HRQOL by Short-Form 8 Health Survey (SF-8), and activities of daily living. Variables associated with quality of sleep, HRQOL in univariate analysis with p < 0.05 were entered into multivariate analysis using logistic regression with a stepwise forward selection procedure to determine independent variables and their association with major causes. The logistic regression analysis was done using SPSS software and the post-hoc power of the study was estimated using G*power. The level of significance was set at p < 0.05. The risk factor of poor sleep quality was because of history of cancer [odds ratio (OR): 3.53, 95% confidence interval (CI): 1.06 - 11.77], and insomnia (OR: 3.25, 95% CI: 1.55 - 6.79). The risk factors of poor physical HRQOL were motor disease (OR: 2.62, 95% CI: 1.36 - 5.07), respiratory disease (OR: 3.24, 95% CI: 1.27 - 8.26) and having pain (OR: 11.71, 95% CI: 5.35 - 25.66). In addition, anemia was found to be a risk factor of poor mental HRQOL (OR: 4.87, 95% CI: 1.11 - 21.33). The feeling-for-their-body-age (OR: 0.30, 95% CI: 0.15-0.59) was as “younger than actual age” and advanced the risk factor of poor sleep quality. In addition, feeling-for-their-age (OR: 0.44, 95% CI: 0.21 - 0.92) resulted in reduced risk factor of poor physical HRQOL. The risk factor of poor sleep quality was due to a patient with history of cancer. The factor for good sleep quality and the good factor for physical HRQOL were indications of feeling younger than the actual age

Delphi Method Consensus-Based Identification of Primary Trauma Care Skills Required for General Surgeons in Japan

Purpose General surgeons at regional hospitals should have the primary trauma care skills necessary to treat critically ill trauma patients to withstand transfer. This study was conducted to identify a consensus on primary trauma care skills for general surgeons. Methods An initial list of acute care surgical skills was compiled, and revised by six trauma experts (acute care surgeons); 33 skills were nominated for inclusion in the Delphi consensus survey. Participants (councilors of the Japanese Society for Acute Care Surgery) were presented with the list of 33 trauma care skills and were asked (using web-based software) to rate how strongly they agreed or disagreed (using a 5-point Likert scale) with the necessity of each skill for a general surgeon. The reliability of consensus was predefined as Cronbach’s α ≥ 0.8, and trauma care skills were considered as primarily required when rated 4 (agree) or 5 (strongly agree) by ≥ 80% participants. Results There were 117 trauma care specialists contacted to participate in the Delphi consensus survey panel. In the 1st round, 85 specialists participated (response rate: 72.6%). In the 2nd round, 66 specialists participated (response rate: 77.6%). Consensus was achieved after two rounds, reliability using Cronbach’s α was 0.94, and 34 items were identified as primary trauma care skills needed by general surgeons. Conclusion A consensus-based list of trauma care skills required by general surgeons was developed. This list can facilitate the development of a new trauma training course which has been optimized for general surgeons
