Characterization of the First Cultured Psychrotolerant Representative of from Antarctica Reveals Its Unique Genome Structure.

Culture-independent analysis shows that spp. inhabit a wide range of low-temperature environments, but to date, no psychrotolerant or psychrophilic strains have been reported. Here, we characterized the first cultivated psychrotolerant representative, designated strain TUM19329, isolated from an Antarctic lake using a polyphasic approach and comparative genomic analysis.

Human change and adaptation in Antarctica: Psychological research on Antarctic wintering-over at Syowa station.

An Antarctic wintering-over station is a unique environment, as a small isolated society facing extreme survival margins. Psychological surveys have been done over ten years, including the Baum test, the Positive and Negative Affect Schedule (PANAS), the Coping Orientation to Problems Experienced (COPE), Subjective Health Complaints Inventory (SHC), the Two-Sided Personality Scale (TSPS) and medical consultations in Syowa Station, a Japanese Antarctic station to reveal the mental status of team members. Team members experienced fewer physical health risks in Antarctica than in Japan.

Chasing Waterborne Pathogens in Antarctic Human-Made and Natural Environments, with Special Reference to spp.

Waterborne pathogenic diseases are public health issues, especially for people staying in remote environments, such as Antarctica. After repeated detection of by PCR from the shower room of Syowa Station, the Japanese Antarctic research station, we wanted to understand the occurrence of waterborne pathogens, especially , in the station and their potential sources. In this study, we analyzed water and biofilm samples collected from the water facilities of Syowa Station, as well as water samples from surrounding glacier lakes, by 16S rRNA gene-based amplicon sequencing.

Evaluating Health Impact at High Altitude in Antarctica and Effectiveness of Monitoring Oxygen Saturation.

Background: The Japanese Antarctic Research Expedition (JARE) has been conducting research activities in inland Antarctica, which is extremely cold dryland covered with a thick ice sheet. This environment may cause a health disorder called acute mountain sickness (AMS). To improve the safety of expedition members, we evaluated the impact of extreme environmental conditions on human health and the effectiveness of monitoring of hypoxia for the early detection of AMS.

Complete Genome Sequence of Novel Psychrotolerant Strain TUM19329, Isolated from Antarctic Lake Sediment.

Here, we report the complete genome sequence characteristics of strain TUM19329, a candidate for a novel psychrotolerant species isolated from Antarctic lake sediment. The genome assembly contains a single 3,750,805-bp contig with a G+C content of 39.1% and is predicted to encode 3,538 proteins.

Disease and injury statistics of Japanese Antarctic research expeditions during the wintering period: evaluation of 6837 cases in the 1st-56th parties - Antarctic health report in 1956-2016.

This study aimed to evaluate disease and injury trends among wintering members of the Japanese Antarctic Research Expedition. Obtained information is indispensable to the advancement of medical system and research. Summation was performed based on medical records of reports prepared by each expedition over the period 1956-2016.

Impact of Living at the Japanese Antarctic Research Expedition Base on Urinary Status.

Objectives: Urinary disorders are generally well understood, but there are few reports on the urinary status of people living in unusual climates such as the polar regions. We studied the impact of living conditions on the urinary status of members of the Japanese Antarctic Research Expedition.

Methods: This prospective study enrolled 12 consenting members of the wintering party stationed at the Syowa Station in Antarctica between November 2012 and March 2014.

[Anesthetic Management for Laparoscopic Surgery in a Very Elderly Patient with Severe Mitral Regurgitation].

A 90-year-old woman with severe mitral regurgitation underwent laparoscopic cholecystectomy. In her anesthetic management, we used FloTrac system and monitored arterial pressure-based cardiac index (CI), stroke volume (SV), and stroke volume variation (SVV) continuously as the indicators of intraoperative hemodynamics. Although the blood pressure fluctuated highly in Fowler position especially, we could control hemodynamics appropriately by intermittent volume infusion and adjusting administration of cardiovascular agents under monitoring these indicators.

Temporal changes in the skin Malassezia microbiota of members of the Japanese Antarctic Research Expedition (JARE): A case study in Antarctica as a pseudo-space environment.

The International Space Station (ISS) is located approximately 400 km above the Earth. Astronauts staying at the ISS are under microgravity and are thus unable to bathe or shower; instead, they wash their bodies using wet tissues. For astronauts, skin hygiene management is important to maintain the quality of life during long-term stays on the ISS.

[Successful anesthetic management of laparoscopic rectopexy using rocuronium and sugammadex in a patient with Becker muscular dystrophy].

A 70-year-old man with Becker muscular dystrophy (BMD) underwent laparoscopic rectopexy under general anesthesia. For anesthetic induction, we administered total 0.6 mg · kg-1 of rocuronium with titration.

[Evaluation of perioperative blood loss and transfusion in total knee arthroplasty].

Background: Total knee arthroplasty (TKA) is generally associated with considerable blood loss and frequent blood transfusion, which are affected by various factors. We evaluated them retrospectively.

Methods: Fifty-five patients underwent TKA at our facility between January 2008 and December 2011.

Intestinal anisakiasis treated successfully with conservative therapy: importance of clinical diagnosis.

Intestinal anisakiasis is not only a rare parasitic disease, but is also difficult to diagnose. The symptoms are not specific and are often very severe and abrupt, and the findings of clinical imaging are very remarkable. Therefore, intestinal anisakiasis is often misdiagnosed as acute abdomen or intestinal obstruction and is treated surgically.

Practical experience of telehealth between an Antarctic station and Japan.

The Japanese Antarctic Research Expedition (JARE) has had a presence in Antarctica since 1956. The Syowa station is 15,000 km from Japan and evacuation of patients is impossible during the winter months. From 1956 to 2003, a total of 4932 telemedical consultations were undertaken, i.

Use of hand-held ultrasonography to confirm the correct placement of a central venous catheter tip.

To avoid severe complications resulting from malpositioning of a central venous catheter, removal and recannulation of the catheter may be necessary, thus wasting medical equipment and increasing stress on the patient. Therefore, central venous catheters should be inserted correctly the first time. We tested whether real-time hand-held ultrasound-guided confirmation of the location of the tip of a central venous catheter inserted from the femoral vein could reduce the rate of malpositioning.

Morbidity and health survey of wintering members in Japanese Antarctic research expedition.

Study Design: The Japanese Antarctic Research Expedition (JARE) started in 1956. Syowa Station is the mother station of JARE at 69 degrees 00'S and 39 degrees 35'E in East Antarctica. An epidemiological survey of the wintering team of JARE was carried out based on the annual reports of JARE over the period 1956-2001.
