Purpose: There are limited data regarding changes in glucose control in pediatric patients with type 1 diabetes (T1D) affected by coronavirus disease 2019 (COVID-19). This study aimed to evaluate changes in the metrics of a continuous glucose monitoring (CGM) system during COVID-19 infection in children and adolescents with T1D. Methods: Eighteen patients with T1D (<18 years of age) were included in this retrospective study. The effects of COVID-19 on CGM metrics were assessed at 5 time points (2 weeks before COVID-19 [time 1], 1 week before COVID-19 [time 2], during COVID-19 [time 3], 1 week after COVID-19 [time 4], and 2 weeks after COVID-19 [time 5]). Results: All participants had at least 1 symptom of COVID-19 and did not need to be hospitalized. The glucose management indicator (GMI) was higher at time 3 (7.7%±1.4%) compared to time 1 (7.1%±1.1%; P=0.016) and time 5 (7.0%±1.2%; P=0.008). According to the insulin delivery method, the GMI at time 3 was significantly higher than that at time 5 in patients treated with multiple daily injections (MDI) (median and interquartile range, 8.0% [6.1%–8.5%] vs. 7.1% [5.8%–7.9%]; P=0.020) but not in those treated with continuous subcutaneous insulin infusion (CSII). Conclusion Pediatric patients with T1D and mild COVID-19 showed worsening glycemic control during COVID-19 infection, but it returned to preinfection levels within 2 weeks of infection. CSII is more effective in maintaining stable glycemic control during COVID-19 infection than is MDI therapy.

Background: Improving β-cell function can lead to remission in some patients with type 2 diabetes mellitus (T2DM). However, research on pharmacotherapy-induced remission in youth-onset T2DM remains scarce. Our study aimed to identify the clinical characteristics of pediatric patients who experience remission. Methods: We retrospectively reviewed 88 pediatric patients with T2DM followed for at least 1 year at Seoul National University Bundang Hospital between 2013 and 2023. Remission was defined as a glycosylated hemoglobin (HbA1c) level less than 6.5% for at least 3 months after ceasing glucose-lowering pharmacotherapy. Results: Among 88 patients (60 males, 68.2%) diagnosed at an average age of 14.4±2.1 years, 19 patients (21.6%) achieved remission after a median duration of 1.4 years. The remission group had a larger proportion of males (89.5% vs. 62.3%, P=0.024) and a lower urinary albumin-to-creatinine ratio (ACR) at diagnosis (P=0.011). They also showed lower HbA1c levels at 1 year and more significant changes in HbA1c and body mass index (all P<0.05). Higher urinary ACR levels correlated with a longer duration to achieve remission (hazard ratio, 0.928; P= 0.013). In three of the 19 remission patients (15.8%), recurrence occurred after a median of 1.5 years. Conclusion Among Korean youth with T2DM, 21.6% achieved remission after a median duration of 1.4 years.Those who experienced remission were predominantly male, had lower ACR at diagnosis, and had significant weight loss within the first year. Further investigation into the factors influencing remission and long-term outcomes is essential.

Breast cancer is the most common cancer in women worldwide, and its early detection is critical for improving survival outcomes. As a diagnostic and screening tool, mammography can be less effective owing to the masking effect of fibroglandular tissue, but breast US has good sensitivity even in dense breasts. However, breast US is highly operator dependent, highlighting the need for artificial intelligence (AI)-driven solutions. Unlike other modalities, US is performed using a handheld device that produces a continuous real-time video stream, yielding 12000–48000 frames per examination. This can be significantly challenging for AI development and requires real-time AI inference capabilities. In this review, we classified AI solutions as computer-aided diagnosis and computer-aided detection to facilitate a functional understanding and review commercial software supported by clinical evidence.In addition, to bridge healthcare gaps and enhance patient outcomes in geographically under resourced areas, we propose a novel framework by reviewing the existing AI-based triage workflows including mobile ultrasound.

Purpose: To evaluate the efficacy and safety of ultrasonography- and fluoroscopy-guided transvaginal catheter drainage for pelvic fluid collection. Materials and Methods: This single-center retrospective study included nine female patients who underwent transvaginal drainage for pelvic fluid collection unsuitable for transabdominal access between October 2016 and January 2023. The study analyzed patient symptoms and signs, ultrasonography and CT findings, transvaginal approach details, and technical and clinical outcomes, including complications. Catheters of size 7 or 8.5-Fr, with or without an endocavitary needle guide were used for the puncture. Results: Pelvic fluid collections were primarily post-operative (n = 7) or from patients with primary tubo-ovarian abscesses (n = 2). All patients achieved technical success, defined as the successful insertion of the drainage catheter at the site of target fluid collection, and clinical success, defined as the improvement of symptoms with catheter removal within 1 week. In seven cases, the procedure was assisted by an endocavitary needle guide. The median catheter indwelling period was 2 days, with two minor complications: accidental catheter removal and urinary bladder puncture, both of which were managed without further complications. Conclusion Ultrasonography- and fluoroscopy-guided transvaginal drainage are effective and safe methods for managing pelvic fluid collections that are unsuitable for a transabdominal approach.

Background: This study analyzed the status of community-based practice in public healthcare institutions in Korean medical schools and identified related needs. Methods: We conducted an online cross-sectional survey in which 32 of 40 medical schools (80.0%) participated between March and April 2023. We developed questionnaire items aimed at ascertaining the status and perceptions of community-based practice and analyzed the response data using frequency analysis, the Mann-Whitney U test, and content analysis with word clouds. Results: Of the 32 medical schools analyzed, 23 (71.9%) offered practical courses, and of those, 12 (52.2%) implemented practice lessons within courses. Among 20 schools, 18 (90.0%) required students to complete practical courses and over 50% offered these courses in the third and fourth years of the clerkship phase. Perceptions of community practice showed no significant differences based on whether courses were offered. Many schools have proposed that practice should be a continuous curricular element from the premedical to medical years. The primary challenges facing community-based practice were identified as faculty development, collaboration, and compensation of practice institutions. The following words were extracted from the respondents’ comments: practice, community, institution, student, education, faculty, university, and public. Conclusion This study identified the limitations of community-based education provided by Korean medical schools and we report findings that highlight areas of improvement. Notable among these is the need to continuously incorporate community-based practice into medical education while engaging in discussions and conducting research toward developing a comprehensive and systematic curriculum.

Background: Although total intravenous anesthesia (TIVA) with propofol and remifentanil is frequently used to optimize intraoperative neurophysiological monitoring (IONM), the exact effect of remimazolam on IONM remains unknown. Here, we compared the effects of propofol and remimazolam along with remifentanil on IONM during TIVA. Methods: In this prospective, double-blind, randomized controlled trial, 64 patients requiring IONM during cervical spine surgery were administered either propofol (Group P) or remimazolam (Group R). The preoperative latencies of the somatosensory-evoked potentials (SEP; N20 for the median nerve and P37 for the tibial nerve) were measured. SEP latencies and amplitudes and motor-evoked potential (MEP) amplitudes were measured 30 min after anesthetic induction (T1), 30 min after surgical incision (T2), after laminectomy or discectomy (T3), immediately after plate insertion or pedicle screw fixation (T4), and before surgical wound closure (T5). The primary outcome was the between-group difference in the N20 latency changes measured at T1 and preoperatively. Results: The change in SEP latencies including N20 and P37 at T1 compared with preoperative time was not significantly different between Groups P and R. Except for the amplitude of the right abductor brevis, there was no significant group-by-time interaction effect for intraoperative MEP amplitudes or SEP latencies and amplitudes. Conclusions TIVA with remimazolam and remifentanil for cervical spine surgery yielded stable IONM, comparable to those observed with conventional TIVA with propofol and remifentanil. Further clinical trials are needed in other surgical contexts and with more diverse patient populations to determine the effects of remimazolam on IONM.

Long coronavirus disease (COVID) is a condition in which coronavirus disease 2019 (COVID-19) symptoms persist for over 3 months, and currently poses a global public health challenge. Due to varying manifestations and lack of standardized definitions, diagnostic methods, and treatments, comprehensive clinical guidelines are required. This review article, summarizing research and expert consensus up to June 2023, provides recommendations for diagnosis and long-term management of long COVID symptoms. It emphasizes thorough patient evaluation, including medical history, physical examinations, and tests, and advocates vaccination and antiviral treatments to reduce risk. Guidelines for long COVID will be updated as new knowledge emerges.
