Purpose: To report the results of a 2021 questionnaire survey assessing the current trends and practice patterns in the treatment of uveitis, conducted by the Korean Uveitis Society (KUS). Methods: To understand the current treatment and trends for uveitis in Korea, a total of 11 questions were surveyed in November 2021 among 300 members of the KUS. This survey comprised 11 multiple choice and dichotomy questions. Results: Of 300 participants, 179 responded, and the response rate was 59.7%. Among the respondents, 92.7% were retina specialists and 66.9% reported less than 10% of uveitis patients among outpatients. As imaging tests performed in patients with anterior uveitis, fundus photography and optical coherence tomography were typically performed (83.8% vs. 73.2%, respectively). The frequently performed blood tests for general screening were complete blood count, blood chemistry test, erythrocyte sedimentation rate, and C-reactive protein (89.9% vs. 86.2% vs. 85.5% vs. 82.4%, respectively). Regarding local steroid treatment, subtenon injection was the most preferred (74.9%). Regarding systemic oral corticosteroids, 83.7% of respondents commonly used initial doses of 0.5-1 mg/kg. Cyclosporine, methotrexate, mycophenolate mofetil, and azathioprine were used for steroid-refractory uveitis patients in that order (36.2% vs. 34.8% vs. 21.7% vs. 7.3%, respectively). Concerning the currently used biologic agent, adalimumab was the most preferred, at 96.7%. Conclusions This survey highlights the recent trends and practice patterns in the treatment of uveitis in Korea.

This study was conducted to investigate whether memory accuracy can be assessed by analyzing electrophysiological responses (i.e., electroencephalography [EEG]) for retrieval cues related to the witnessed scene. Specifically, we examined the different patterns of EEG signals recorded during witnessed (target) and unwitnessed (lure) stimuli using event-related potential (ERP) analysis. Moreover, using multivariate pattern analysis, we also assessed how accurately single-trial EEG signals can classify target and lure stimuli. Participants watched a staged-crime video (theft crime), and the EEG signals evoked by the objects shown in the video were analyzed (n=56). Compared to the target stimulus, the lure stimulus elicited larger negative ERPs in frontal brain regions 300 to 500 milliseconds after the retrieval cue was presented. Furthermore, the EEG signals observed 450 to 500 milliseconds after the retrieval cue was presented showed the best classification performance related to eyewitness memory, with the mean classification accuracy being 56%. These results suggest that the knowledge and techniques of cognitive neuroscience can be used to estimate eyewitness memory accuracy.

We investigated the neural correlates of accurate eyewitness memory retrieval using functional near-infrared spectroscopy. We analyzed oxygenated hemoglobin (HbO₂) concentration in the prefrontal cortex during eyewitness memory retrieval task and examined regional HbO₂ differences between observed objects (target) and unobserved objects (lure). We found that target objects elicited increased activation in the bilateral ventrolateral prefrontal cortex, which is known for monitoring retrieval processing via bottom-up attentional processing. Our results suggest bottom-up attentional mechanisms could be different during accurate eyewitness memory retrieval. These findings indicate that investigating retrieval mechanisms using functional nearinfrared spectroscopy might be useful for establishing an accurate eyewitness recognition model.

BACKGROUND: Significant clinical heterogeneity within contemporary risk group is well known, particularly for those with intermediate-risk prostate cancer (IRPCa). Our study aimed to analyze the ability of the Cancer of the Prostate Risk Assessment (CAPRA) score to discern between favorable and non-favorable risk in patients with IRPCa. METHODS: We retrospectively reviewed the data of 203 IRPCa patients who underwent extraperitoneal robot-assisted radical prostatectomy (RARP) performed by a single surgeon. Pathologic favorable IRPCa was defined as a Gleason score ≤ 6 and organ-confined stage at surgical pathology. The CAPRA score was compared with two established criteria for the within-group discrimination ability. RESULTS: Overall, 38 patients (18.7% of the IRPCa cohort) had favorable pathologic features after RARP. The CAPRA score significantly correlated with established criteria I and II and was inversely associated with favorable pathology (all P < 0.001). The area under the receiver operating characteristic curve for the discriminative ability between favorable and non-favorable pathology was 0.679 for the CAPRA score and 0.610 and 0.661 for established criteria I and II, respectively. During a median 37.8 (interquartile range, 24.6–60.2) months of follow-up, 66 patients (32.5%) experienced biochemical recurrence (BCR). Cox regression analysis revealed that the CAPRA score, as a continuous sum score model or 3-group risk model, was an independent predictor of BCR after RARP. CONCLUSION: The within-group discrimination ability of preoperative CAPRA score might help in patient counseling and selecting optimal treatments for those with IRPCa.

We investigated the neural correlates of accurate eyewitness memory retrieval using functional near-infrared spectroscopy. We analyzed oxygenated hemoglobin (HbOâ‚‚) concentration in the prefrontal cortex during eyewitness memory retrieval task and examined regional HbOâ‚‚ differences between observed objects (target) and unobserved objects (lure). We found that target objects elicited increased activation in the bilateral ventrolateral prefrontal cortex, which is known for monitoring retrieval processing via bottom-up attentional processing. Our results suggest bottom-up attentional mechanisms could be different during accurate eyewitness memory retrieval. These findings indicate that investigating retrieval mechanisms using functional nearinfrared spectroscopy might be useful for establishing an accurate eyewitness recognition model.

Eleven compounds (1–11) were isolated from the rhizomes of Osmunda japonica, and their structures were elucidated based on 1H, 13C-NMR and LC-IT-TOF MS data. Of these compounds, all compounds (1 – 11) have been previously reported, although five (6 – 9, 11) have not previously been isolated from this plant. The antioxidant activities of isolated compounds (1 – 11) were measured by DPPH and ABTS assays, and compound 10 showed the high antioxidant activity.

We evaluated the effects of eye movements on facial feature recognition and memory retrieval. Thirty-eight participants learned the faces of five men, including features of the faces (eyes, nose, and mouth), and then performed a recognition memory task for partially manipulated versions of the faces. Bilateral eye movements, recognition accuracy, and mean fixation duration were evaluated. We observed differences in fixation durations for the manipulated features of the faces (eyes, F(3,78)=11.95, P<0.001; and mouth, F(3,78)=21.38, P<0.001). These findings demonstrate that eye movements have a functional role in learning and recognizing human faces. Furthermore, fixation durations increased for the manipulated facial features, suggesting that eye movements during recognition are not simply patterns produced during learning.

We investigated event-related potentials (ERPs) to estimate the accuracy of eyewitness memories. Participants watched videos of vehicles being driven dangerously, from an anti-impaired driving initiative. The four-letter license plates of the vehicles were the target stimuli. Random numbers were presented while participants attempted to identify the license plate letters, and electroencephalograms were recorded. There was a significant difference in activity 300-500 milliseconds after stimulus onset, between target stimuli and random numbers. This finding contributes to establishing an eyewitness recognition model where different ERP components may reflect more explicit memory that is dissociable from recollection.

The purpose of this study was to determine whether contemporary active surveillance (AS) protocols could sufficiently discriminate significant from indolent tumors in men with low-risk prostate cancer. We retrospectively analyzed 312 patients with low-risk prostate cancer treated with radical prostatectomy. After exclusion of patients with fewer than 10 cores taken at biopsy and those who received neo-adjuvant treatment, 205 subjects satisfied the final inclusion criteria. Five widely accepted AS protocols were employed in this study. A total of 82.0% of the patients met the inclusion criteria of at least one protocol, and 18% did not meet any criteria of published AS protocols. A significant proportion of patients had non-organ-confined disease (8.6% to 10.6%) or a Gleason score of 7 or greater (18.6% to 23.9%) between the different AS criteria. Among patients who did not meet any AS criteria, 32.4% of patients had a pathologically insignificant cancer. Our results indicated a significant adverse pathology in patients who met the contemporary AS protocols. On the other hand, some patients in whom expectant management would be appropriate did not meet any criteria of published AS protocols. None of the clinical or histological criteria reported to date is able to sufficiently discriminate aggressive tumors from indolent ones.
