Background: To investigate Korean neurologists' perceptions of the non-standard term ‘jayulsingyeongsiljo’ and their actual evaluation and management of such patients. Methods: We performed an anonymous web-based cross-sectional survey of board-certified Korean neurologists by Korean Society of Pain and Autonomic Disorders between August 13 and September 10, 2025. A questionnaire sent by e-mail asked about demographics, experience with patients labeled with ‘jayulsingyeongsiljo,’ use and perceived usefulness of autonomic function tests, the impact of coronavirus disease 2019, and opinions on terminology and the role of neurologists. Results: In total, 109 neurologists responded. Most reported that patients presenting for ‘jayulsingyeongsiljo’ were young or middle-aged adults and that their numbers had increased over the preceding 2 years. Referrals frequently originated from Korean medicine clinics and other non-neurology departments, often after stand-alone heart rate variability testing. Fatigue, orthostatic intolerance, palpitations, sweating abnormalities, gastrointestinal symptoms, and anxiety or insomnia were common, and autonomic testing was generally regarded as helpful. Eighty percent felt that the risks associated with ‘jayulsingyeongsiljo’ are overstated, and 95% preferred replacing the term with standardized expressions such as autonomic dysfunction. Conclusions Korean neurologists view ‘jayulsingyeongsiljo’ as an unrecognized and potentially misleading label and support society-led standardization of terminology and guidance to improve autonomic dysfunction care and resource use.

Purpose: We investigated the level of glaucoma awareness and identified associated factors among Korean adults aged ≥40 years using data from the Korea National Health and Nutrition Examination Survey (KNHANES). Methods: Among the 16,154 individuals aged ≥40 years who underwent ophthalmic examinations in the 2017-2020 KNHANES, 825 participants diagnosed with glaucoma by an ophthalmologist were included. Glaucoma awareness was defined as a self-reported history of physician-diagnosed glaucoma. Associations between glaucoma awareness and sociodemographic variables including age, sex, education level, income level, and recent ophthalmic examination were evaluated using chi-square tests and logistic regression analyses. Results: Among the 16,154 participants, 825 (5.1%) were diagnosed with glaucoma. However, only 19.8% were aware of their condition and 14.0% reported were receiving treatment. In logistic regression analysis, older age was significantly associated with greater awareness (≥80 years vs. 40-49 years; p < 0.001). Recent ophthalmic examination within 1 year was significantly associated with higher awareness (≤1 year vs. 1-3 years; p < 0.001). Sex, education level, and income level were not independently associated with glaucoma awareness. Conclusions Although glaucoma awareness among Korean adults has more than doubled compared to the 8.0% reported in previous KNHANES analyses, over 80% of affected individuals remain unaware of their diagnosis. Awareness was significantly associated with older age and recent ophthalmic examination emphasizing the importance of regular eye screening. Considering the anticipated rise in glaucoma prevalence, incorporating systematic ophthalmic screening into the national health check-up program should be considered to enhance early detection and management.

Purpose: This study aimed to compare perioperative and postoperative outcomes of single-port laparoscopic articulated instrument-assisted versus da Vinci SP-assisted totally extraperitoneal (TEP) inguinal hernia repair using a propensity score-matched multi-institutional cohort. Methods: Between April 2022 and July 2025, 221 patients underwent TEP unilateral inguinal hernia repair at four institutions. Among them, 33 patients underwent da Vinci SP-assisted repair (Intuitive Surgical) and 188 underwent single-port laparoscopy using the articulated instrument, ArtiSential (LivsMed). Propensity score matching was performed in a 1:1 ratio based on demographic and clinical variables, resulting in 30 matched patients in each group. Perioperative outcomes and postoperative complications were analyzed. Results: After matching, baseline characteristics were well balanced between the groups.Operative time was significantly longer in the da Vinci SP group than in the ArtiSential group (median [interquartile range], 82.0 [67.5–105.0] vs. 35.0 [28.5–47.5] minutes; p < 0.001). No open conversions occurred, and conversions to transabdominal preperitoneal repair were rare and comparable. Mesh size selection differed significantly, with smaller meshes more frequently used in the da Vinci SP group (p < 0.001). Postoperative outcomes, including length of hospital stay, overall complication rates, chronic pain, and recurrence, were similar between the groups. No major complications, readmissions, or reoperations were observed. Conclusion Articulated instrument-assisted TEP inguinal hernia repair demonstrated a significantly shorter operative time than da Vinci SP-assisted repair, while perioperative safety and postoperative outcomes were comparable.

Background: Early oral switch (EOS) has been proposed as an alternative to prolonged intravenous (IV) therapy for Enterobacterales bacteremia; however, its safety and effectiveness have not been clearly established. This systematic review and meta-analysis evaluated whether EOS reduces treatment failure in uncomplicated Enterobacterales bacteremia and examined how the timing of switching affects outcomes. Methods: We conducted a systematic review and random-effects meta-analysis of randomized controlled trials and observational studies that compared EOS with continued IV therapy in adults with uncomplicated Enterobacterales bacteremia. Pooled risk ratios (RRs) with 95% confidence intervals (CIs) were calculated using random-effects models. The primary outcome was treatment failure by ≤90 days. Prespecified analyses evaluated the timing of the switch. Results: Across 10 studies that met the inclusion criteria, EOS was associated with lower treatment failure than continued IV therapy (RR, 0.72; 95% CI, 0.58–0.89; I²=26%). Switching within 4 days reduced the failure (RR, 0.58; 95% CI, 0.44–0.76; I²=0%), whereas switching after 4 days showed no clear advantage (RR, 0.87; 95% CI, 0.71–1.06; I²=0%). No evidence of small study effects was observed. Conclusion EOS was associated with a lower risk of treatment failure than prolonged IV therapy, with the greatest benefit observed when the switch occurred within 4 days. These findings should be interpreted with clinical caution given that most of the evidence is observational.

Objective: Cardiac arrest and cardiopulmonary resuscitation (CA/R) lead to whole-body ischemia and reperfusion (IR) injury, causing multiple organ dysfunction, including ischemic spinal cord injury. The thoracic spinal cord levels are crucial for maintaining the sympathetic functions vital for life. This study examined blood-spinal cord barrier (BSCB) leakage and astrocyte endfeet (AEF) disruption and their effects on survival, physiological variables, and neuronal damage/death in the intermediate zone (IMZ) at the seventh thoracic spinal cord level after asphyxial CA/R in rats. Methods: The rats underwent whole-body IR injury by asphyxial CA/R. Kaplan-Meier analysis was conducted to assess the cumulative survival post-CA/R. The histological changes post-CA/R were evaluated using immunohistochemistry, histofluorescence, and double histofluorescence. Results: No significant differences in body weight, mean arterial pressure, and heart rate were found between the sham and CA/R groups post-CA/R. The survival rates in the CA/R group at 12, 24, and 48 hours were 62.58%, 36.37%, and 7.8%, respectively. Neuronal loss and BSCB leakage began 12 hours post-CA/R, increasing with time. Reactive astrogliosis appeared at 12 hours and increased, while AEF disruption around blood vessels was evident at 48 hours. Conclusion The survival rate declined significantly by 48 hours post-CA/R. Neuronal loss and BSCB leakage in the thoracic spinal cord IMZ was evident at 12 hours and significant by 48 hours, aligning with AEF disruption. Neuronal loss in the thoracic spinal cord IMZ post-CA/R may be related to BSCB leakage and AEF disruption.

Purpose: The classification of asthma phenotypes frequently depends on the age of onset. However, the rationale for specific age cutoffs remains unclear. This study aimed to explore the distribution of asthma onset age, to define subgroups based on onset age, and to examine their characteristics within a broad Korean population. Methods: An analysis of cross-sectional data involving 56,632 participants from the Korean National Health and Nutrition Examination Survey (2010–2016) was conducted. Data on asthma history, including diagnosis, self-reported age of asthma onset, and current disease status, were collected using structured questionnaires. Results: The distribution of asthma onset age showed a distinct peak in early childhood, with a decline between the ages 15 and 20.Based on this distribution, asthma was categorized into childhood-onset ( ≤ 18 years) and adult-onset ( > 18 years) for further analysis.Multivariate analyses indicated that adult-onset asthma was associated with older age, female sex, obesity, and a history of smoking, whereas childhood-onset asthma was linked to younger age, male sex, allergic rhinitis, and atopic dermatitis. Among the adultonset group, current asthma had a later onset age, increased history of smoking history, and atopic dermatitis compared to past asthma. Conclusion This analysis of nationwide general population data suggests that an age threshold around 18 years may be relevant for defining adult-onset asthma.
