However, the Gleason grade group (GGG) often differs between needle-core biopsy (NCB) and radical prostatectomy (RP) specimens. We investigated the diagnostic value of a second opinion pathology review using NCB specimens in PCa. Materials and Methods: We retrospectively evaluated 882 patients who underwent robot-assisted RP from January 2012 to September 2019. Of these, patients whose original biopsy specimens were obtained from another hospital and reviewed by the urological pathology expert at our institution were included in the study. Patients who received neoadjuvant hormonal therapy were excluded from the study. Weighted kappa (k) coefficients were used to evaluate the diagnostic accuracy of each review. Results: A total of 497 patients were included in this study. Substantial agreement (weighted k = 0.783) in the GGG between initial- and second-opinion diagnoses based on NCB specimens was observed in 310 cases (62.4%). Although diagnoses based on a single opinion showed moderate agreement with the GGG of RP specimens (initial: 35.2%, weighted k = 0.522; second opinion; 38.8%, weighted k = 0.560), matching initial and second opinion diagnoses improved the concordance (42.9%, 133/310 cases) to substantial agreement (weighted k = 0.626). Conclusions: A second opinion of PCa pathology helps to improve the diagnostic accuracy of NCB specimens. However, over half of diagnoses that matched between the initial and second opinions differed from the diagnosis of RP specimens. en-copyright= kn-copyright= en-aut-name=MaeharaTakanori en-aut-sei=Maehara en-aut-mei=Takanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SadahiraTakuya en-aut-sei=Sadahira en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MaruyamaYuki en-aut-sei=Maruyama en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WadaKoichiro en-aut-sei=Wada en-aut-mei=Koichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ArakiMotoo en-aut-sei=Araki en-aut-mei=Motoo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=WatanabeMasami en-aut-sei=Watanabe en-aut-mei=Masami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=WatanabeToyohiko en-aut-sei=Watanabe en-aut-mei=Toyohiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YanaiHiroyuki en-aut-sei=Yanai en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NasuYasutomo en-aut-sei=Nasu en-aut-mei=Yasutomo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Departments of Urology and 1Pathology, Graduate School of Medicine Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Departments of Urology and 1Pathology, Graduate School of Medicine Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Departments of Urology and 1Pathology, Graduate School of Medicine Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Departments of Urology and 1Pathology, Graduate School of Medicine Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Departments of Urology and 1Pathology, Graduate School of Medicine Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Departments of Urology and 1Pathology, Graduate School of Medicine Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Departments of Urology and 1Pathology, Graduate School of Medicine Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Departments of Urology and 1Pathology, Graduate School of Medicine Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Departments of Urology and 1Pathology, Graduate School of Medicine Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Gleason grade group kn-keyword=Gleason grade group en-keyword=Gleason score kn-keyword=Gleason score en-keyword=prostate biopsy kn-keyword=prostate biopsy en-keyword=prostate cancer kn-keyword=prostate cancer en-keyword=prostatectomy kn-keyword=prostatectomy END start-ver=1.4 cd-journal=joma no-vol=7 cd-vols= no-issue=1 article-no= start-page=8 end-page=12 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210330 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=An Examination of mobile spinal cord stimulators on treating Parkinson disease en-subtitle= kn-subtitle= en-abstract= kn-abstract=In animal models of Parkinson disease (PD), spinal cord stimulation (SCS) exhibits neuroprotective effects. Recent advancements in SCS technology, most importantly mobile stimulators, allow for the conventional limitations of SCS such as limited stimulation time and restricted animal movements to be bypassed, offering potential avenues for improved clinical translation to PD patients. Small devices that could deliver continuous SCS to freely moving parkinsonian rats were shown to significantly improve behavior, preserve neurons and fibers in the substantia Nigra/striatum, reduce microglia infiltration, and increase laminin-positive area of the cerebral cortex. Through possible anti-inflammatory and angiogenic mechanisms, it has been demonstrated that there are behavioral and histological benefits to continuous SCS in a time-dependent manner. This review will discuss the benefits of this technology as well as focus on the limitations of current animal models. en-copyright= kn-copyright= en-aut-name=WangZhen-Jie en-aut-sei=Wang en-aut-mei=Zhen-Jie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YasuharaTakao en-aut-sei=Yasuhara en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Department of Neurosurgery and Brain Repair, Morsani College of Medicine, University of South Florida kn-affil= affil-num=2 en-affil=Department of Neurological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=6 hydroxydopamine kn-keyword=6 hydroxydopamine en-keyword=electrical stimulation kn-keyword=electrical stimulation en-keyword=neuroinflammation kn-keyword=neuroinflammation en-keyword=neuroprotection kn-keyword=neuroprotection en-keyword=Parkinson disease kn-keyword=Parkinson disease END
