First Report of the Non-Native Raccoon (Procyon lotor) on Nakanoshima Islands in Lake Toya, Hokkaido, Japan
Currently, the raccoon (Procyon lotor) has expanded its distribution throughout Japan and is present in 44 of the 47 prefectures. Delaying the spread is useful for invasive species management; however, there is no information on the dispersal distance and swimming movement of raccoons. The objective of this study is to report the first record of a raccoon on Nakanoshima Islands in Hokkaido, northern Japan. We conducted camera trap survey on 26 825 camera trap-days during 2019–2024, and recorded raccoons eight times in 2022 and 2023. Although it is difficult to determine the number of raccoons from still images, this species likely entered this island by swimming movement. Information on the movement of this species, including its overwater movement, will be useful in predicting the expansion of its distribution into low-density areas and in establishing effective strategies at the distribution edge, including countermeasures such as early detection and rapid response.現在, アライグマ(Procyon lotor)は, 日本全国に分布を拡大しており, 44 都道府県に生息している.外来種管理において, 分布の拡散スピードを遅らせることは有効であるが, アライグマの分散距離や遊泳移動に関する情報は皆無である.本研究の目的は, 北海道洞爺湖中島におけるアライグマの初記録を報告することである.本研究は, 2019 年から 2024 年にかけて 26 825 日間にわたりカメラトラップ調査を実施し, 2022 年と 2023 年においてアライグマを 8 回記録した.静止画からアライグマの個体数を特定することは困難であるが, 本種が遊泳移動によりこの島に侵入した可能性がある.本種の遊泳移動を含む移動に関する生態を把握することは, 早期発見や迅速な対応などの対策に繋がり, 低密度地域への分布拡大の予測や分布辺縁部での効果的な戦略の確立に重要な情報となるだろう.journal articl
Characterizing Intra- and Inter-Individual Variability in Nocturnal Sleep Patterns in Alzheimer’s Disease Using a Bed Sensor System
Aim : This study characterized intra- and inter-individual variability in nocturnal sleep patterns in older adults with Alzheimer’s disease (AD) using a non-invasive bed sensor system and compared them with cognitively normal (CN) older adults. Methods : Sleep was continuously monitored for about 30 days in 9 AD and 10 CN participants using the Nemuri SCAN system. Nocturnal total sleep time (N-TST) was classified as short (<360 min), standard (360-600 min), or long ( ≥600 min). Results : The AD group exhibited three distinct N-TST patterns : mostly standard sleep, predominantly long sleep, and highly variable durations. Only one-third of AD participants had ≥75 % standard sleep days compared with 80 % of CN participants, while over half of AD participants had frequent long sleep days. Conclusion : These findings indicate substantial individual variability and a tendency toward long sleep in AD, emphasizing the importance of personalized sleep assessment and management in this population.

A Case of Portal Vein Thrombosis after Cesarean Section
Portal vein thrombosis (PVT) commonly occurs in patients with liver cirrhosis and may be caused by hypercoagulable states, such as malignancy, infection, or thrombophilia. Without appropriate treatment, PVT may develop into life-threatening conditions, such as liver failure, disseminated intravascular coagulation, mesenteric vein thrombosis, and intestinal necrosis. We herein report a case of PVT after cesarean section in a woman with no underlying medical conditions. The patient was a 35-year-old multiparous woman with no previous medical complications. She underwent elective cesarean section at 38 weeks’ gestation for indications of pregnancy after a previous cesarean section. When she walked on the first postoperative day, her oxygen saturation decreased to 89 % ; therefore, pulmonary thromboembolism was suspected. Contrast-enhanced computed tomography was performed and showed no pulmonary embolism, but revealed a thrombus of the portal vein in hepatic segment 8. PVT was diagnosed and anticoagulant therapy was immediately initiated. Liver enzymes remained normal at diagnosis, increased transiently on postoperative day 6, and subsequently normalized. She underwent routine abdominal ultrasound, and the portal vein thrombus disappeared 9 weeks after cesarean section. A blood examination was conducted to clarify why the patient developed PVT ; however, she had no predisposition to thrombosis. Since the thrombus was detected early and treatment was promptly initiated, the patient did not develop severe complications. Pregnancy and cesarean section were considered potential triggers for PVT. This case highlights the need to recognize PVT as a possible manifestation of venous thromboembolism in peripartum management. Shinshu Med J 74 : 51―57, 2026journal articl
