Purpose: To investigate the role of combined periprostatic nerve block (PNB) and intrarectal local anesthesia with heated lidocaine gel (ILAHL) in reducing pain during transrectal ultrasound (TRUS)-guided prostate biopsy, compared with PNB alone. Materials and Methods: We performed a prospective randomized trial with 140 participants who underwent systematic TRUS-guid ed, 12-core prostate biopsy from July 2021 to June 2022. These participants were divided into two groups. Before prostate biopsy, group 1 (n=70) received PNB and group 2 (n=70) received PNB combined intrarectal local anesthesia with 20 mL of heated (40ºC) 2% lidocaine gel. The primary outcome was pain score on a 0–10 visual analogue scale (VAS) at four time points (VAS A: during local anesthesia procedure, VAS B: during probe insertion, VAS C: during biopsy procedure, VAS D: 30 minutes after biopsy). The secondary outcome included adverse events during and after the procedure. Results: Mean pain scores were significantly lower in group 2 than in group 1 at VAS A (2.53 vs. 1.60, p=0.001) and VAS B (2.47 vs.1.49, p<0.001). The mean VAS C pain score in group 2 was significantly less than in group 1 (3.07 vs. 2.20, p=0.001), while there was no significant difference in the mean VAS D pain score between two groups (1.06 vs. 0.89, p=0.318). There were no significant differences in the occurrence of complications in both groups. Conclusions The combination of PNB and ILAHL provides more effective pain control than PNB alone without increase of complication rates in patients undergoing TRUS-guided prostate biopsy.

Background and Objectives: This study aimed to analyze postoperative performance and mapping characteristics of cochlear implants (CIs) by comparing patients with autism spectrum disorder (ASD) to those without ASD, and to suggest CI mapping solutions in patients with ASD.Subjects and Method This retrospective study enrolled 10 children with ASD and hearing disabilities, who received simultaneous bilateral CI (ASD group), and 20 children with bilateral hearing disabilities, who received simultaneous bilateral CI at the same age (control group). CI performance was analyzed using speech perception tests (categorical auditory performance score and monosyllable, bisyllable, and Ling’s 6 tests) and a sound field test. The mapping characteristics focused on variables related to stimulus intensity and fine-tuning. Results: The performance of the ASD group was significantly poorer than that of the control group in all speech perception and sound field tests. At the comfortable (C) and threshold (T) levels, the ASD group scored significantly lower than the control group. The dynamic range of ASD group was significantly narrower than the control group. The ASD group had significantly lower pulse width, sensitivity, and volume than control group. Conclusion CI mapping in the ASD group showed practical limitations. To avoid overstimulation in patients with ASD, the dynamic range should be set narrow, or the C/T level should be set lower than normal. Key control factors, such as pulse width, sensitivity, and volume, should be set lower than the control group. Although lower performance from CI is generally expected in the ASD group, CI mapping in the ASD group requires a long-term approach with dedicated efforts and patience.

Background: The significance of risk modification in patients with acute coronary syndrome (ACS) is well recognized; however, the optimal timing for adminstering PCSK9 inhibitors remains unclear. Additionally, the lipid-lowering efficacy of evolocumab and alirocumab has not been fully established. This study evaluated the lipid-lowering effects of these two PCSK9 inhibitors. Methods: Patients diagnosed with ACS, including unstable angina, ST-segment elevation myocardial infarction, and non-ST-segment elevation myocardial infarction, who were treated with a PCSK9 inhibitor (evolocumab or alirocumab) during hospitalization for ACS between 2021 and 2023 were retrospectively analyzed. Baseline low-density lipoprotein cholesterol (LDL-C) levels were assessed, and changes in LDL-C levels during the acute and subacute phases after PCSK9 inhibitor administration were compared between the evolocumab and alirocumab groups. Results: Among 80 patients diagnosed with ACS, 36 received evolocumab, while 44 were treated with alirocumab. The mean baseline LDL-C level was 123 mg/dL in the evolocumab group and 128 mg/dL in the alirocumab group (p=0.456). In the subacute phase, the mean follow-up LDL-C levels were 47.05 mg/dL in the evolocumab group and 49.5 mg/dL in the alirocumab group (p=0.585). The mean percentage reduction in LDL-C levels during the subacute phase was 60.41% in the evolocumab group and 58.51% in the alirocumab group (p=0.431). These differences were not statistically significant. Conclusions No significant differences were observed between evolocumab and alirocumab. LDL-C levels exhibited a similar trend, characterized by a rapid decline in the acute phase, followed by a slight rebound in the subacute phase.

Objective: This study aims to investigate may moesin deficiency resulted in neurodevelopmental abnormalities caused by negative impact on synaptic signaling ultimately leading to synaptic structure and plasticity. Methods: Behavioral assessments measured neurodevelopment (surface righting, negative geotaxis, cliff avoidance), anxiety (open field test, elevated plus maze test), and memory (passive avoidance test, Y-maze test) in moesin-knockout mice (KO) compared to wild-type mice (WT). Whole exome sequencing (WES) of brain (KO vs. WT) and analysis of synaptic proteins were performed to determine the disruption of signal pathways downstream of moesin. Risperidone, a therapeutic agent, was utilized to reverse the neurodevelopmental aberrance in moesin KO. Results: Moesin-KO pups exhibited decrease in the surface righting ability on postnatal day 7 (p<0.05) and increase in time spent in the closed arms (p<0.01), showing increased anxiety-like behavior. WES revealed mutations in pathway aberration in neuron projection, actin filament-based processes, and neuronal migration in KO. Decreased cell viability (p<0.001) and expression of soluble NSF adapter protein 25 (SNAP25) (p<0.001) and postsynaptic density protein 95 (PSD95) (p<0.01) was observed in days in vitro 7 neurons. Downregulation of synaptic proteins, and altered phosphorylation levels of Synapsin I, mammalian uncoordinated 18 (MUNC18), extracellular signal-regulated kinase (ERK), and cAMP response element-binding protein (CREB) was observed in KO cortex and hippocampus. Risperidone reversed the memory impairment in the passive avoidance test and the spontaneous alternation percentage in the Y maze test. Risperidone also restored the reduced expression of PSD95 (p<0.01) and the phosphorylation of Synapsin at Ser605 (p<0.05) and Ser549 (p<0.001) in the cortex of moesin-KO. Conclusion Moesin deficiency leads to neurodevelopmental delay and memory decline, which may be caused through altered regulation in synaptic proteins and function.

Purpose: To evaluate the feasibility and utility of deep learning-based computer-aided diagnosis (DL-CAD) for the detection of pulmonary nodules on coronary artery calcium (CAC)-scoring computed tomography (CT). Materials and Methods: This retrospective study included 273 patients (aged 63.9±13.2 years; 129 men) who underwent CACscoring CT. A DL-CAD system based on thin-section images was used for pulmonary nodule detection, and two independent junior readers reviewed the standard CAC-scoring CT scans with and without referencing DL-CAD results. A reference standard was established through the consensus of two experienced radiologists. Sensitivity, positive predictive value, and F1-score were assessed on a per-nodule and per-patient basis. The patients’ medical records were monitored until November 2023. Results: A total of 269 nodules were identified in 129 patients. With DL-CAD assistance, the readers’ sensitivity significantly improved (65% vs. 80% for reader 1; 82% vs. 86% for reader 2; all p<0.001), without a notable increase in the number of false-positives per case (0.11 vs. 0.13, p=0.078 for reader 1; 0.11 vs. 0.11, p>0.999 for reader 2). Per-patient analysis also enhanced sensitivity with DL-CAD assistance (73% vs. 84%, p<0.001 for reader 1; 89% vs. 91%, p=0.250 for reader 2). During follow-up, lung cancer was diagnosed in four patients (1.5%). Among them, two had lesions detected on CAC-scoring CT, both of which were successfully identified by DL-CAD. Conclusion DL-CAD based on thin-section images can assist less experienced readers in detecting pulmonary nodules on CACscoring CT scans, improving detection sensitivity without significantly increasing false-positives.
