A 60-year-old Japanese man with a history of scleroderma, pulmonary fibrosis, and type 2 diabetes developed acute myocardial infarction of the right coronary artery (RCA) and was treated by emergency percutaneous coronary intervention (PCI) for RCA. Nine days later he underwent PCI from the LMT to the LAD. Follow-up coronary angiography (CAG) at 9 and 21 months post-PCI did not reveal ISR in any lesion, but the patient experienced cardiac arrest at 25 months post-PCI. Emergency CAG after resuscitation revealed ISR of the LMT ostium; emergency PCI was conducted. The development of ISR at the ostium of the LMT although the patient was free of plaque 4 months before is extremely unusual. This rare ISR of the LMT ostium progressed rapidly after follow-up CAG revealed no ISR at 21 months post-stent implantation. en-copyright= kn-copyright= en-aut-name=NaitoYoichiro en-aut-sei=Naito en-aut-mei=Yoichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YoshikawaMasaki en-aut-sei=Yoshikawa en-aut-mei=Masaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NakamuraKazufumi en-aut-sei=Nakamura en-aut-mei=Kazufumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KuboMotoki en-aut-sei=Kubo en-aut-mei=Motoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SugiyamaHiroyasu en-aut-sei=Sugiyama en-aut-mei=Hiroyasu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SuzukiHideyuki en-aut-sei=Suzuki en-aut-mei=Hideyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=FujitaShinpei en-aut-sei=Fujita en-aut-mei=Shinpei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=AraiYasunori en-aut-sei=Arai en-aut-mei=Yasunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TakahashiSho en-aut-sei=Takahashi en-aut-mei=Sho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KatoYuichi en-aut-sei=Kato en-aut-mei=Yuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=YoshidaYu en-aut-sei=Yoshida en-aut-mei=Yu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=AkaiHiroaki en-aut-sei=Akai en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=MurakamiShuhei en-aut-sei=Murakami en-aut-mei=Shuhei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=ItoHiroshi en-aut-sei=Ito en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= affil-num=1 en-affil=Department of Cardiovascular Medicine, Fukuyama City Hospital kn-affil= affil-num=2 en-affil=Department of Cardiovascular Medicine, Fukuyama City Hospital kn-affil= affil-num=3 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Cardiovascular Medicine, Fukuyama City Hospital kn-affil= affil-num=5 en-affil=Department of Cardiovascular Medicine, Fukuyama City Hospital kn-affil= affil-num=6 en-affil=Department of Cardiovascular Medicine, Fukuyama City Hospital kn-affil= affil-num=7 en-affil=Department of Cardiovascular Medicine, Fukuyama City Hospital kn-affil= affil-num=8 en-affil=Department of Cardiovascular Medicine, Fukuyama City Hospital kn-affil= affil-num=9 en-affil=Department of Cardiovascular Medicine, Fukuyama City Hospital kn-affil= affil-num=10 en-affil=Department of Cardiovascular Medicine, Fukuyama City Hospital kn-affil= affil-num=11 en-affil=Department of Cardiovascular Medicine, Fukuyama City Hospital kn-affil= affil-num=12 en-affil=Department of Cardiovascular Medicine, Fukuyama City Hospital kn-affil= affil-num=13 en-affil=Department of Cardiovascular Medicine, Fukuyama City Hospital kn-affil= affil-num=14 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=left main trunk kn-keyword=left main trunk en-keyword=in-stent restenosis kn-keyword=in-stent restenosis en-keyword=cardiopulmonary arrest kn-keyword=cardiopulmonary arrest END start-ver=1.4 cd-journal=joma no-vol=76 cd-vols= no-issue=1 article-no= start-page=93 end-page=98 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202202 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Cystic Intracranial Recurrence of Olfactory Neuroblastoma without Accumulation on Fluorine-18-fluorodeoxyglucose Positron Emission Tomography en-subtitle= kn-subtitle= en-abstract= kn-abstract=A 66-year-old man underwent multimodal treatment for olfactory neuroblastoma (ONB). When he was 72 years old, a cystic intracranial lesion without accumulation on fluorine-18-fluorodeoxyglucose positron emission tomography was detected. Surgical resection was performed when the patient was 73 years old. The pathological examination revealed recurrence of ONB, and the patient underwent focal irradiation. At age 81, he presented with a second recurrence in the right occipital lobe with radiological and pathological findings similar to the prior recurrence. This case suggests that pathological confirmation should be considered in cases with atypical radiological findings following the treatment of ONB. en-copyright= kn-copyright= en-aut-name=IshiYukitomo en-aut-sei=Ishi en-aut-mei=Yukitomo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamaguchiShigeru en-aut-sei=Yamaguchi en-aut-mei=Shigeru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HatanakaKanako C. en-aut-sei=Hatanaka en-aut-mei=Kanako C. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakakuwaEmi en-aut-sei=Takakuwa en-aut-mei=Emi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MotegiHiroaki en-aut-sei=Motegi en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HondaTaishi en-aut-sei=Honda en-aut-mei=Taishi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KobayashiHiroyuki en-aut-sei=Kobayashi en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TerasakaShunsuke en-aut-sei=Terasaka en-aut-mei=Shunsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=HommaAkihiro en-aut-sei=Homma en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=FujimuraMiki en-aut-sei=Fujimura en-aut-mei=Miki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=HoukinKiyohiro en-aut-sei=Houkin en-aut-mei=Kiyohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Neurosurgery, Faculty of Medicine and Graduate School of Medicine, Hokkaido University kn-affil= affil-num=2 en-affil=Department of Neurosurgery, Faculty of Medicine and Graduate School of Medicine, Hokkaido University kn-affil= affil-num=3 en-affil=Department of Surgical Pathology, Hokkaido University Hospital kn-affil= affil-num=4 en-affil=Department of Surgical Pathology, Hokkaido University Hospital kn-affil= affil-num=5 en-affil=Department of Neurosurgery, Faculty of Medicine and Graduate School of Medicine, Hokkaido University kn-affil= affil-num=6 en-affil=Department of Neurosurgery, Faculty of Medicine and Graduate School of Medicine, Hokkaido University kn-affil= affil-num=7 en-affil=Department of Neurosurgery, Faculty of Medicine and Graduate School of Medicine, Hokkaido University kn-affil= affil-num=8 en-affil=Department of Neurosurgery, Faculty of Medicine and Graduate School of Medicine, Hokkaido University kn-affil= affil-num=9 en-affil=Department of Otolaryngology-Head & Neck Surgery, Faculty of Medicine and Graduate School of Medicine, Hokkaido University kn-affil= affil-num=10 en-affil=Department of Neurosurgery, Faculty of Medicine and Graduate School of Medicine, Hokkaido University kn-affil= affil-num=11 en-affil=Department of Neurosurgery, Faculty of Medicine and Graduate School of Medicine, Hokkaido University kn-affil= en-keyword=cystic recurrence kn-keyword=cystic recurrence en-keyword=esthesioneuroblastoma kn-keyword=esthesioneuroblastoma en-keyword=fluorine-18-fluorodeoxyglucose positron emission tomography kn-keyword=fluorine-18-fluorodeoxyglucose positron emission tomography en-keyword=intracranial recurrence kn-keyword=intracranial recurrence en-keyword=olfactory neuroblastoma kn-keyword=olfactory neuroblastoma END start-ver=1.4 cd-journal=joma no-vol=76 cd-vols= no-issue=1 article-no= start-page=89 end-page=92 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202202 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Completely Video-assisted Thoracoscopic Lobectomy for Congenital Lobar Emphysema in a Young Adult en-subtitle= kn-subtitle= en-abstract= kn-abstract=Congenital lobar emphysema (CLE) is defined as the hyperinflation of pulmonary lobes due to obstruction of the flow of air via a known or unknown etiology, which causes pressure symptoms in the adjacent organs. CLE is mainly diagnosed in the neonatal period, and very few adult cases have been reported. Here we report a 34-year-old male with muscular dystrophy who was diagnosed with CLE on examination. He underwent a right lower lobectomy via 3-portal completely video-assisted thoracoscopic surgery, and his symptoms improved. Thoracoscopic surgery helped preserve the respiratory muscles and led to the improvement of respiratory function in this patient. en-copyright= kn-copyright= en-aut-name=RyukoTsuyoshi en-aut-sei=Ryuko en-aut-mei=Tsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamamotoHiromasa en-aut-sei=Yamamoto en-aut-mei=Hiromasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SugimotoSeiichiro en-aut-sei=Sugimoto en-aut-mei=Seiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SuzawaKen en-aut-sei=Suzawa en-aut-mei=Ken kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MiyoshiKentaroh en-aut-sei=Miyoshi en-aut-mei=Kentaroh kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OtaniShinji en-aut-sei=Otani en-aut-mei=Shinji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OkazakiMikio en-aut-sei=Okazaki en-aut-mei=Mikio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YamaneMasaomi en-aut-sei=Yamane en-aut-mei=Masaomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ToyookaShinichi en-aut-sei=Toyooka en-aut-mei=Shinichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Thoracic Surgery, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Thoracic Surgery, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Thoracic Surgery, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Thoracic Surgery, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Thoracic Surgery, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Thoracic Surgery, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Thoracic Surgery, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Thoracic Surgery, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Thoracic Surgery, Okayama University Hospital kn-affil= en-keyword=congenital lobar emphysema, kn-keyword=congenital lobar emphysema, en-keyword=adult, kn-keyword=adult, en-keyword=lobectomy, kn-keyword=lobectomy, en-keyword=completely video-assisted thoracoscopic surgery, kn-keyword=completely video-assisted thoracoscopic surgery, en-keyword=muscular dystrophy kn-keyword=muscular dystrophy END start-ver=1.4 cd-journal=joma no-vol=76 cd-vols= no-issue=1 article-no= start-page=85 end-page=88 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202202 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Lumbar Artery Injury Related to Percutaneous Pedicle Screw Insertion en-subtitle= kn-subtitle= en-abstract= kn-abstract=A 75-year-old woman underwent L4-L5 lateral interbody fusion for L4-5 foraminal stenosis with the use of percutaneous pedicle screws.

A radiologist performed a successful transarterial embolization, and the patient then began walking training on the 4th day post-surgery. Close attention should be paid to the insertion of a percutaneous pedicle screw, as it may cause a lumbar artery injury; in such a case, transarterial embolization is the preferred treatment. en-copyright= kn-copyright= en-aut-name=OmiHirotsugu en-aut-sei=Omi en-aut-mei=Hirotsugu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TomitaTakashi en-aut-sei=Tomita en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IchinoheMasayuki en-aut-sei=Ichinohe en-aut-mei=Masayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HaradaYoshifumi en-aut-sei=Harada en-aut-mei=Yoshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SatoHideki en-aut-sei=Sato en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ItoJunji en-aut-sei=Ito en-aut-mei=Junji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Omi Orthopaedic Clinic kn-affil= affil-num=2 en-affil=Department of Orthopaedic Surgery, Aomori Prefectural Central Hospital kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Aomori Prefectural Central Hospital kn-affil= affil-num=4 en-affil=Department of Orthopaedic Surgery, Aomori Prefectural Central Hospital kn-affil= affil-num=5 en-affil=Department of Orthopaedic Surgery, Aomori Prefectural Central Hospital kn-affil= affil-num=6 en-affil=Department of Orthopaedic Surgery, Aomori Prefectural Central Hospital kn-affil= en-keyword=lumbar artery injury kn-keyword=lumbar artery injury en-keyword=percutaneous pedicle screw kn-keyword=percutaneous pedicle screw en-keyword=transverse process fracture kn-keyword=transverse process fracture en-keyword=hematoma kn-keyword=hematoma END start-ver=1.4 cd-journal=joma no-vol=76 cd-vols= no-issue=1 article-no= start-page=79 end-page=84 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202202 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Fixed Partial Denture Designed by Combining the Whole 3D Digital Surface Morphology of the Provisional Restoration and Abutment Teeth Surfaces en-subtitle= kn-subtitle= en-abstract= kn-abstract=We introduce a new digital workflow to fabricate a fixed partial denture (FPD) utilizing the three-dimensional surface morphology of provisional restoration (PR) and abutment teeth.

The established treatment is fixation with a C1 lateral mass screw and C2 pedicle screw (modified Goel technique). However, this technique requires fluoroscopy for C1 screw insertion. To avoid exposing the operating team to radiation we present here a new C-arm free O-arm navigated surgical procedure for pediatric AAS in DS. A 5-year-old male DS patient had neck pain and unsteady gait. Radiograms showed AAS with an atlantodental interval of 10 mm, and irreducible subluxation on extension. CT scan showed Os odontoideum and AAS. MRI demonstrated spinal cord compression between the C1 posterior arch and odontoid process. We performed a C-arm free O-arm navigated modified Goel procedure with postoperative halo-vest immobilization. At oneyear follow-up, good neurological recovery and solid bone fusion were observed. The patient had no complications such as epidural hematoma, infection, or nerve or vessel injury. This novel procedure is a useful and safe technique that protects surgeons and staff from radiation risk. en-copyright= kn-copyright= en-aut-name=TanakaMasato en-aut-sei=Tanaka en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SonawaneSumeet en-aut-sei=Sonawane en-aut-mei=Sumeet kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FujiwaraYoshihiro en-aut-sei=Fujiwara en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=UotaniKoji en-aut-sei=Uotani en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=AratakiShinya en-aut-sei=Arataki en-aut-mei=Shinya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YamauchiTaro en-aut-sei=Yamauchi en-aut-mei=Taro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YeYouchen en-aut-sei=Ye en-aut-mei=Youchen kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MisawaHaruo en-aut-sei=Misawa en-aut-mei=Haruo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=2 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=4 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=5 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=6 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=7 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=8 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= en-keyword=atlantoaxial fixation kn-keyword=atlantoaxial fixation en-keyword=Down syndrome kn-keyword=Down syndrome en-keyword=C-arm free kn-keyword=C-arm free en-keyword=O-arm navigation surgery kn-keyword=O-arm navigation surgery en-keyword=modified Goel technique kn-keyword=modified Goel technique END start-ver=1.4 cd-journal=joma no-vol=76 cd-vols= no-issue=1 article-no= start-page=63 end-page=70 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202202 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Chidamide and Decitabine in Combination with a HAG Priming Regimen for Acute Myeloid Leukemia with TP53 Mutation en-subtitle= kn-subtitle= en-abstract= kn-abstract=We analyzed the treatment effects of chidamide and decitabine in combination with a HAG (homoharringtonine, cytarabine, G-CSF) priming regimen (CDHAG) in acute myeloid leukemia (AML) patients with TP53 mutation. Seven TP53 mutated AML patients were treated with CDHAG. The treatment effects were assessed using hemogram detection and bone marrow aspirate. The possible side effects were evaluated based on both hematological and non-hematological toxicity. Four of the seven patients were classified as having achieved complete remission after CDHAG treatment; one patient was considered to have achieved partial remission, and the remaining two patients were considered in non-remission. The overall response rate (ORR) to CDHAG was 71.4%. Regarding the side effects, the hematological toxicity level of the seven patients ranged from level III to level IV, and infections that occurred at lung, blood, and skin were recorded. Nausea, vomiting, liver injury, and kidney injury were also detected. However, all side effects were attenuated by proper management. The CDHAG regimen clearly improved the ORR (71.4%) of TP53-mutated AML patients, with no severe side effects. en-copyright= kn-copyright= en-aut-name=ZhangBei en-aut-sei=Zhang en-aut-mei=Bei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=PeiZhixin en-aut-sei=Pei en-aut-mei=Zhixin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=WangHongxia en-aut-sei=Wang en-aut-mei=Hongxia kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WuHuimin en-aut-sei=Wu en-aut-mei=Huimin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=WangJunjie en-aut-sei=Wang en-aut-mei=Junjie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=BaiJunjun en-aut-sei=Bai en-aut-mei=Junjun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SongQinglin en-aut-sei=Song en-aut-mei=Qinglin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Hematology, Jiaozuo Peoplefs Hospital kn-affil= affil-num=2 en-affil=Department of Hematology, Jiaozuo Peoplefs Hospital kn-affil= affil-num=3 en-affil=Department of Hematology, Jiaozuo Peoplefs Hospital kn-affil= affil-num=4 en-affil=Department of Hematology, Jiaozuo Peoplefs Hospital kn-affil= affil-num=5 en-affil=Department of Hematology, Jiaozuo Peoplefs Hospital kn-affil= affil-num=6 en-affil=Department of Hematology, Jiaozuo Peoplefs Hospital kn-affil= affil-num=7 en-affil=Department of Hematology, Jiaozuo Peoplefs Hospital kn-affil= en-keyword=acute myeloid leukemia kn-keyword=acute myeloid leukemia en-keyword=chidamide kn-keyword=chidamide en-keyword=decitabine kn-keyword=decitabine en-keyword=HAG kn-keyword=HAG en-keyword=TP53 mutation kn-keyword=TP53 mutation END start-ver=1.4 cd-journal=joma no-vol=76 cd-vols= no-issue=1 article-no= start-page=57 end-page=62 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202202 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=In Vivo Microwave Ablation of Normal Swine Lung at High-power, Short-duration Settings en-subtitle= kn-subtitle= en-abstract= kn-abstract=To evaluate the volume and heat-sink effects of microwave ablation (MWA) in the ablation zone of the normal swine lung. MWA at 100 W was performed for 1, 2, and 3 min in 7, 5, and 5 lung zones, respectively. We assessed the histopathology in the ablation zones and other outcome measures: namely, length of the longest long and short axes, sphericity, ellipsoid area, and ellipsoid volume. The mean long- and short-axis diameters were 22.0 and 14.1 mm in the 1-min ablation zone, 27.6 and 20.2 mm in the 2-min ablation zone; and 29.2 and 21.2 mm in the 3-min ablation zone, respectively. All measures, except sphericity, were significantly less with 1-min ablation than with either 2- or 3-min ablation. There were no significant differences between the 2- and 3-min ablation zones, but all measures except sphericity were larger with 3-min ablation. Although there were no blood vessels that resulted in a heat-sink effect within the ablation zones, the presence of bronchi nearby in 5 lung ablation zones resulted in reduced ablation size. In high-power, short-duration MWA, the lung ablation volume was affected by ablation time. Some ablations showed that a heat-sink effect by a neighboring bronchus might occur. en-copyright= kn-copyright= en-aut-name=IguchiToshihiro en-aut-sei=Iguchi en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HirakiTakao en-aut-sei=Hiraki en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MatsuiYusuke en-aut-sei=Matsui en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TojiTomohiro en-aut-sei=Toji en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=UkaMayu en-aut-sei=Uka en-aut-mei=Mayu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TomitaKoji en-aut-sei=Tomita en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KomakiToshiyuki en-aut-sei=Komaki en-aut-mei=Toshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=UmakoshiNoriyuki en-aut-sei=Umakoshi en-aut-mei=Noriyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MitsuhashiToshiharu en-aut-sei=Mitsuhashi en-aut-mei=Toshiharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KanazawaSusumu en-aut-sei=Kanazawa en-aut-mei=Susumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Radiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Radiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Radiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Pathology, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Radiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Radiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Radiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Radiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of Radiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=microwave ablation kn-keyword=microwave ablation en-keyword=lung kn-keyword=lung en-keyword=ablation zone kn-keyword=ablation zone en-keyword=heat-sink effect kn-keyword=heat-sink effect en-keyword=swine kn-keyword=swine END start-ver=1.4 cd-journal=joma no-vol=76 cd-vols= no-issue=1 article-no= start-page=51 end-page=56 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202202 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Obesityfs Influence on Insulin Resistance in Pregnant Women with Polycystic Ovary Syndrome en-subtitle= kn-subtitle= en-abstract= kn-abstract=Polycystic ovary syndrome (PCOS) is a common endocrine metabolic disorder that is associated with high insulin resistance and obesity. However, ~70% of women with PCOS in Japan are non-obese. We retrospectively analyzed the cases of 163 Japanese women with PCOS who visited our Ob/Gyn department in 2006-2018 to determine which has a greater effect on insulin resistance: PCOS or obesity. We reviewed the womenfs medical records and calculated their insulin resistance and insulin secretion. The womenfs mean age and pre-pregnancy body mass index (BMI) were 30}5.8 years and 24.8}5.6 kg/m2, respectively; their mean } SD fasting plasma glucose, 94.1}13.7 mg/dL; HOMA-IR, 2.1}2.0; QUICKI, 0.4}0.0; and HOMA-ƒÀ, 108.9}88.0%. Sixtyeight women were pregnant, and 37% (n=25) were obese (BMI ? 25 kg/m2). Obesity had a greater effect on insulin resistance: fasting plasma glucose F(1, 53)=6.134, p<0.05; fasting insulin F(1, 53)=31.606, p<0.01; HOMA-IR F(1, 53)=31.670, p<0.01; QUICKI F(1, 53)=16.156, p<0.01. There was no significant difference in values other than QUICKI and testosterone between the women with and without PCOS. Obesity thus had a greater effect on increased insulin resistance in pregnant women with PCOS. Further studies of the insulin resistance of non-obese women with PCOS is needed, as non-obese women with PCOS are common in Asia. en-copyright= kn-copyright= en-aut-name=EtoEriko en-aut-sei=Eto en-aut-mei=Eriko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TaniKazumasa en-aut-sei=Tani en-aut-mei=Kazumasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MakiJota en-aut-sei=Maki en-aut-mei=Jota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HayataKei en-aut-sei=Hayata en-aut-mei=Kei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MasuyamaHisashi en-aut-sei=Masuyama en-aut-mei=Hisashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=polycystic ovary syndrome kn-keyword=polycystic ovary syndrome en-keyword=insulin resistance kn-keyword=insulin resistance en-keyword=obesity kn-keyword=obesity en-keyword=pregnancy kn-keyword=pregnancy END start-ver=1.4 cd-journal=joma no-vol=76 cd-vols= no-issue=1 article-no= start-page=41 end-page=49 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202202 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Urinary Protein-to-creatinine Ratios Predict Recurrence in Pediatric and Young Adult Cases of Minimal Change Nephrotic Syndrome en-subtitle= kn-subtitle= en-abstract= kn-abstract=High-dose steroids are required for the treatment of minimal change nephrotic syndrome (MCNS), especially for episodes of recurrence. Predicting and avoiding recurrence can help reduce the steroid dose, but prediction is currently difficult. We herein examined whether changes in laboratory data, especially the urinary protein- to-creatinine ratio (UTP/UCr), can predict clinical recurrence. We also assessed differences in clinical features between children and young adults. We included 36 patients with MCNS; for each case, we retrospectively studied laboratory data during stable remission and pre-recurrence, with the gstableh period defined as all but the 6 weeks before recurrence, and pre-recurrence defined as the 4}2 weeks before recurrence. UTP/UCr, serum albumin, etc. were measured every 5 years during stable periods. We divided patients into cohorts by age at recurrence, < 15 years and ? 15 years, and compared stable and pre-recurrence values for the two groups. UTP/UCr values during stable periods tended to be higher in younger patients. UTP/UCr and serum albumin showed statistically significant changes during pre-recurrence periods, but only in those aged ? 15 years. Thus, clinical features of recurrence differed depending on age. Signs of recurrence can be confirmed via UTP/UCr or serum albumin several weeks before recurrence in patients ? 15 years. en-copyright= kn-copyright= en-aut-name=MiyaharaHiroyuki en-aut-sei=Miyahara en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MiyaiTakayuki en-aut-sei=Miyai en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AyaKunihiko en-aut-sei=Aya en-aut-mei=Kunihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TsukaharaHirokazu en-aut-sei=Tsukahara en-aut-mei=Hirokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=4 en-affil=Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=minimal change nephrotic syndrome kn-keyword=minimal change nephrotic syndrome en-keyword=recurrence kn-keyword=recurrence en-keyword= urinary protein to creatinine ratio kn-keyword= urinary protein to creatinine ratio END start-ver=1.4 cd-journal=joma no-vol=76 cd-vols= no-issue=1 article-no= start-page=33 end-page=39 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202202 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Plasma Concentrations of Trace Elements Selenium and Cobalt During and After Coronary Artery Bypass Grafting Surgery en-subtitle= kn-subtitle= en-abstract= kn-abstract=Trace elements selenium (Se) and cobalt (Co) are essential in the human body, and a correlation between Se and cardiac surgery has been suggested. We investigated the plasma concentrations of Se and Co during and after coronary artery bypass grafting (CABG) surgery under cardiopulmonary bypass (CPB). From December 2019 to January 2020, preoperative plasma samples from isolated first-time CABG patients (n=20; 10 males, 10 females) were prospectively collected post-anesthesia and before CPB (T1), 45 min after CPB started (T2), 90 min after CPB started (T3), and postoperative days 1 (T4), and day 4 (T5). The plasma concentrations of Se and Co were measured. The Se concentration was significantly decreased at T2 (105.24}4.08 vs. 68.56}2.42 ƒÊg/L, p<0.001) and T3 (105.24}4.08 vs. 80.41}3.40 ƒÊg/L, p<0.001). The Co concentration was significantly decreased at T4 (0.35}0.19 vs. 0.26}0.13 ƒÊg/L, p<0.01) and T5 (0.35}0.19 vs. 0.23}0.11 ƒÊg/L, p<0.001). Five patients developed atrial fibrillation (AF); there was no other operative mortality or major morbidity. This is the first report of alterations of plasma Se and Co concentrations during and after CABG surgery. Our results may indicate that Se supplementation before or during CABG and Co supplementation after CABG may become necessary for patients undergoing CABG. en-copyright= kn-copyright= en-aut-name=ZhouJia-Yi en-aut-sei=Zhou en-aut-mei=Jia-Yi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HouHai-Tao en-aut-sei=Hou en-aut-mei=Hai-Tao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=WangShi-Fu en-aut-sei=Wang en-aut-mei=Shi-Fu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YangQin en-aut-sei=Yang en-aut-mei=Qin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HeGuo-Wei en-aut-sei=He en-aut-mei=Guo-Wei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=The Institute of Cardiovascular Diseases & Department of Cardiovascular Surgery, TEDA International Cardiovascular Hospital kn-affil= affil-num=2 en-affil=Unit of Perfusion, Department of Cardiovascular Surgery, TEDA International Cardiovascular Hospita kn-affil= affil-num=3 en-affil=Unit of Perfusion, Department of Cardiovascular Surgery, TEDA International Cardiovascular Hospital kn-affil= affil-num=4 en-affil=The Institute of Cardiovascular Diseases & Department of Cardiovascular Surgery, TEDA International Cardiovascular Hospital kn-affil= affil-num=5 en-affil=The Institute of Cardiovascular Diseases & Department of Cardiovascular Surgery, TEDA International Cardiovascular Hospital kn-affil= en-keyword=trace element kn-keyword=trace element en-keyword=CABG kn-keyword=CABG en-keyword=cardiopulmonary bypass kn-keyword=cardiopulmonary bypass en-keyword=selenium kn-keyword=selenium en-keyword=cobalt kn-keyword=cobalt END start-ver=1.4 cd-journal=joma no-vol=76 cd-vols= no-issue=1 article-no= start-page=25 end-page=32 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202202 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Development and Evaluation of a Short-time Imaging Method for the Clinical Study of the Apparent Diffusion Coefficient Subtraction Method en-subtitle= kn-subtitle= en-abstract= kn-abstract=The apparent diffusion coefficient subtraction method (ASM) was developed as a new restricted diffusionweighted imaging technique for magnetic resonance imaging (MRI). The usefulness of the ASM has been established by in vitro basic research using a bio-phantom, and clinical research on the application of the ASM for the human body is needed. Herein, we developed a short-time sequence for ASM imaging of the heads of healthy volunteers (n=2), and we investigated the similarity between the obtained ASM images and diffusion kurtosis (DK) images to determine the utility of the ASM for clinical uses. This study appears to be the first to report ASM images of the human head. We observed that the short-time sequence for the ASM imaging of the head can be scanned in approx. 3 min at 1.5T MRI. The noise reduction effect of median filter processing was confirmed on the ASM images scanned by this sequence. The obtained ASM images showed a weak correlation with the DK images, indicating that the ASM images are restricted diffusion-weighted images. The new shorttime imaging sequence could thus be used in clinical studies applying the ASM. en-copyright= kn-copyright= en-aut-name=SugimotoKohei en-aut-sei=Sugimoto en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KurodaMasahiro en-aut-sei=Kuroda en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YoshimuraYuuki en-aut-sei=Yoshimura en-aut-mei=Yuuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HamadaKentaro en-aut-sei=Hamada en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KhasawnehAbdullah en-aut-sei=Khasawneh en-aut-mei=Abdullah kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=BarhamMajd en-aut-sei=Barham en-aut-mei=Majd kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TekikiNouha en-aut-sei=Tekiki en-aut-mei=Nouha kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KonishiKohei en-aut-sei=Konishi en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=IshizakaHinata en-aut-sei=Ishizaka en-aut-mei=Hinata kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=ShimizuYudai en-aut-sei=Shimizu en-aut-mei=Yudai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=NakamitsuYuki en-aut-sei=Nakamitsu en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=Al-HammadWlla E. en-aut-sei=Al-Hammad en-aut-mei=Wlla E. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=KamizakiRyo en-aut-sei=Kamizaki en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=KanazawaSusumu en-aut-sei=Kanazawa en-aut-mei=Susumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=AsaumiJunichi en-aut-sei=Asaumi en-aut-mei=Junichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= affil-num=1 en-affil=Radiological Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=2 en-affil=Radiological Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=3 en-affil=Radiological Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=4 en-affil=Radiological Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Oral and Maxillofacial Radiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Oral and Maxillofacial Radiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Oral and Maxillofacial Radiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Radiological Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=9 en-affil=Radiological Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=10 en-affil=Department of Oral and Maxillofacial Radiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Radiological Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=12 en-affil=Department of Oral and Maxillofacial Radiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=13 en-affil=Radiological Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=14 en-affil=Department of Radiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=15 en-affil=Department of Oral and Maxillofacial Radiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=apparent diffusion coefficient kn-keyword=apparent diffusion coefficient en-keyword=apparent diffusion coefficient subtraction method kn-keyword=apparent diffusion coefficient subtraction method en-keyword=diffusion kurtosis imaging kn-keyword=diffusion kurtosis imaging en-keyword=restricted diffusion kn-keyword=restricted diffusion en-keyword=short-time imaging kn-keyword=short-time imaging END start-ver=1.4 cd-journal=joma no-vol=76 cd-vols= no-issue=1 article-no= start-page=17 end-page=24 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202202 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Extending Treatment Intervals of R-CHOP Therapy Might Be Acceptable for Some Patients with Non-indolent Non-Hodgkinfs B-cell Lymphoma en-subtitle= kn-subtitle= en-abstract= kn-abstract=R-CHOP therapy is generally performed every 3 weeks. We investigated the effects of extending the interval of R-CHOP therapy for > 1 week on the prognoses of patients with non-indolent non-Hodgkinfs B-cell lymphoma. Among the 338 patients with non-indolent non-Hodgkinfs B-cell lymphoma who received initial chemotherapy at our institution, we focused on 178 patients who received R-CHOP therapy and analyzed the outcomes of the patients stratified by the treatment intervals. The estimated 3-year overall survival (OS) for the entire population was 82.1%. Patients treated at intervals of ? 4 weeks were significantly older, and they had significantly longer follow-up periods and lower relative dose intensity. But the estimated 3-year OS was comparable to those treated at <4 weeks (83.3% vs. 80.5% p=0.947). In a multivariate analysis, age and the dose of anti-cancer agents had significant impacts on OS, but there was no significant relationship regarding the treatment intervals. Propensity score matching confirmed the same result. R-CHOP therapy every around 4 weeks could achieve relatively good survival in some selected patients with non-indolent non-Hodgkinfs B-cell lymphoma. en-copyright= kn-copyright= en-aut-name=FujishitaKeigo en-aut-sei=Fujishita en-aut-mei=Keigo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YasuhisaSando en-aut-sei=Yasuhisa en-aut-mei=Sando kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OkaSatoshi en-aut-sei=Oka en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FujisawaYuka en-aut-sei=Fujisawa en-aut-mei=Yuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MachidaTakuya en-aut-sei=Machida en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ImaiToshi en-aut-sei=Imai en-aut-mei=Toshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Hematology and Blood Transfusion, Kochi Health Sciences Center kn-affil= affil-num=2 en-affil=Department of Hematology and Blood Transfusion, Kochi Health Sciences Center kn-affil= affil-num=3 en-affil=Department of Hematology and Blood Transfusion, Kochi Health Sciences Center kn-affil= affil-num=4 en-affil=Department of Hematology and Blood Transfusion, Kochi Health Sciences Center kn-affil= affil-num=5 en-affil=Department of Hematology and Blood Transfusion, Kochi Health Sciences Center kn-affil= affil-num=6 en-affil=Department of Hematology and Blood Transfusion, Kochi Health Sciences Center kn-affil= en-keyword=R-CHOP therapy kn-keyword=R-CHOP therapy en-keyword=relative dose intensity kn-keyword=relative dose intensity en-keyword= non-Hodgkinfs lymphoma kn-keyword= non-Hodgkinfs lymphoma END start-ver=1.4 cd-journal=joma no-vol=76 cd-vols= no-issue=1 article-no= start-page=7 end-page=15 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202202 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Aging-related Characteristics of Subclinical Hypothyroidism Detected in General Practice en-subtitle= kn-subtitle= en-abstract= kn-abstract=Subclinical hypothyroidism (SCH) is diagnosed when serum thyrotropin (TSH) is elevated despite a normal thyroxine level and is known to increase the risk of metabolic disorders.

Eighty-five (9.1%) of the 939 analyzed subjects had SCH (73% females). In the SCH group, median serum TSH and FT4 levels were 5.04 ƒÊU/ml and 1.19 ng/dl, respectively, and auto-thyroid antibodies were detected in 53.8% of patients. SCH group patients were significantly older than patients in the euthyroid group, while there was no intergroup difference in BMI. However, 56.5% of the SCH patients were asymptomatic. In the SCH group, serum aspartate aminotransferase and low-density lipoprotein cholesterol (LDL-C) levels were significantly higher, and the estimated glomerular filtration rate (eGFR) was significantly lower than in the euthyroid group. Among patients less than 65 years of age, SCH patients tended to have lower eGFR and higher LDL-C than euthyroid patients. Age-dependent reductions of red blood cells and serum albumin were more prominent in the SCH than the euthyroid group. Biochemical changes with aging are useful as potential clues for suspecting latent SCH. en-copyright= kn-copyright= en-aut-name=TakamiMasao en-aut-sei=Takami en-aut-mei=Masao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamamotoKoichiro en-aut-sei=Yamamoto en-aut-mei=Koichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HanayamaYoshihisa en-aut-sei=Hanayama en-aut-mei=Yoshihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NakanoYasuhiro en-aut-sei=Nakano en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HasegawaKou en-aut-sei=Hasegawa en-aut-mei=Kou kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ObikaMikako en-aut-sei=Obika en-aut-mei=Mikako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HagiyaHideharu en-aut-sei=Hagiya en-aut-mei=Hideharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=FurukawaMasanori en-aut-sei=Furukawa en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OtsukaFumio en-aut-sei=Otsuka en-aut-mei=Fumio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Laboratory Medicine, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=aging kn-keyword=aging en-keyword=renal function kn-keyword=renal function en-keyword=cholesterol kn-keyword=cholesterol en-keyword=subclinical hypothyroidism kn-keyword=subclinical hypothyroidism en-keyword=thyroid function kn-keyword=thyroid function END start-ver=1.4 cd-journal=joma no-vol=76 cd-vols= no-issue=1 article-no= start-page=1 end-page=5 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202202 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Mouse Model for Optogenetic Genome Engineering en-subtitle= kn-subtitle= en-abstract= kn-abstract=Optogenetics, a technology to manipulate biological phenomena thorough light, has attracted much attention in neuroscience. Recently, the Magnet System, a photo-inducible protein dimerization system which can control the intracellular behavior of various biomolecules with high accuracy using light was developed. Furthermore, photoactivation systems for controlling biological phenomena are being developed by combining this technique with genome-editing technology (CRISPR/Cas9 System) or DNA recombination technology (Cre-loxP system). Herein, we review the history of optogenetics and the latest Magnet System technology and introduce our recently developed photoactivatable Cre knock-in mice with temporal-, spatial-, and cell-specific accuracy. en-copyright= kn-copyright= en-aut-name=TakaoTomoka en-aut-sei=Takao en-aut-mei=Tomoka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamadaDaisuke en-aut-sei=Yamada en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakaradaTakeshi en-aut-sei=Takarada en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Regenerative Science, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Regenerative Science, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Regenerative Science, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=optogenetics kn-keyword=optogenetics en-keyword=Cre recombinase kn-keyword=Cre recombinase END
