Objective: A survey was conducted to analyze the concussion care practices of emergency physicians (EPs) and identify the need for educational programs based on concussion care guidelines. Methods: The cross-sectional self-report online survey was conducted over two months in 2023 and engaged emergency medicine residents and board-certified EPs. The survey consisted of questions about the respondents’ information and 23 questions regarding diagnosis practices, discharge instructions, follow-up instructions, and recovery instruction behaviors. The respondents were tasked with categorizing their practices as “usually” (more than 75% of the time); “often” (between 25% and 75% of the time); or “rarely” (less than 25% of the time). Results: Of the 115 participating emergency physicians, 70.4% held board certification. Most respondents (93.9%) usually explained potential emergency symptoms when discharging patients. On the other hand, the symptom scale tools for pediatric patients and screening for recovery-delay risk factors were rarely used. Only 34.8% and 33.0% of respondents usually explained the need for rest before non-contact, light aerobic activities and how to return to sports and physical activity, respectively, because of the lack of familiarity with the discharge and recovery instructions. Conclusion Despite their knowledge of clinical decision rules and guidelines, EPs often struggled to apply them because of time constraints. These results highlight the importance of providing education and training to EPs to enhance their knowledge and skills in concussion care management. By doing so, it is possible to improve the quality of care provided to patients who have suffered concussions and reduce the risk of complications.

This study was designed to compare diagnostic categories of thyroid fine needle aspiration cytology (FNAC) and incidence of thyroid tumors in the multi-institutional Asian series with a special focus on diagnostic category IV (suspicious for a follicular neoplasm) and follicular thyroid carcinomas (FTCs). Methods: Distribution of FNAC categories, incidence of thyroid tumors in resection specimens and cytologic diagnoses of surgically confirmed follicular adenomas (FAs) and FTCs were collected from 10 institutes from five Asian countries and were compared among countries and between FAs and FTCs. Results: The frequency of category IV diagnoses (3.0%) in preoperative FNAC were significantly lower compared to those in Western countries (10.1%). When comparing diagnostic categories among Asian countries, category IV was more frequent in Japan (4.6%) and India (7.9%) than in Taiwan (1.4%), Korea (1.4%), and China (3.6%). Similarly, incidence of FAs and FTCs in surgical resection specimens was significantly higher in Japan (10.9%) and India (10.1%) than in Taiwan (5.5%), Korea (3.0%), and China (2.5%). FTCs were more commonly diagnosed as category IV in Japan (77.5%) than in Korea (33.3%) and China (35.0%). Nuclear pleomorphism, nuclear crowding, microfollicular pattern, and dyshesive cell pattern were more common in FTCs compared with FAs. Conclusions: Our study highlighted the difference in FNAC diagnostic categories of FTCs among Asian countries, which is likely related to different reporting systems and thyroid cancer incidence. Cytologic features such as nuclear pleomorphism, nuclear crowding, microfollicular pattern, and dyshesive cell pattern were found to be useful in diagnosing FTCs more effectively.

This study investigated the status and evaluated factors associated with knowledge and attitudes regarding pediatric concussions among Korean parents of children aged 6 to 18 years. Methods A cross-sectional online survey was employed to collect data from a panel of parents in Korea in 2023. To assess knowledge and attitudes regarding concussions, participants completed a validated questionnaire. The outcome variables of total knowledge score (range, 0–30) and total attitude score (range, 7–49) were categorized into tertiles. We conducted multivariable ordinal logistic regression analyses with participants and their children based on demographic information and characteristics as covariates. Results A total of 260 parents responded to the survey and demonstrated moderate concussion-related knowledge (median total score, 21; interquartile range [IQR], 18–22.5). The respondents exhibited favorable attitudes toward concussions (median total score, 39; IQR, 34–43), except the attitude of the importance of reporting concussion. Multivariable ordinal regression analysis for outcomes revealed only career of healthcare provider (adjusted odds ratio, 3.15; 95% confidence interval, 1.13–8.75) to be associated with parental concussion-related knowledge. No factors exhibited a significant association with parental attitudes toward concussions. Conclusion Our results confirmed the knowledge-attitude gap regarding pediatric concussions among Korean parents. Effective strategies are warranted to improve parental knowledge and attitudes.

Purpose: This subgroup analysis of the Korean subset of patients in the phase 3 LASER301 trial evaluated the efficacy and safety of lazertinib versus gefitinib as first-line therapy for epidermal growth factor receptor mutated (EGFRm) non–small cell lung cancer (NSCLC). Materials and Methods: Patients with locally advanced or metastatic EGFRm NSCLC were randomized 1:1 to lazertinib (240 mg/day) or gefitinib (250 mg/day). The primary endpoint was investigator-assessed progression-free survival (PFS). Results: In total, 172 Korean patients were enrolled (lazertinib, n=87; gefitinib, n=85). Baseline characteristics were balanced between the treatment groups. One-third of patients had brain metastases (BM) at baseline. Median PFS was 20.8 months (95% confidence interval [CI], 16.7 to 26.1) for lazertinib and 9.6 months (95% CI, 8.2 to 12.3) for gefitinib (hazard ratio [HR], 0.41; 95% CI, 0.28 to 0.60). This was supported by PFS analysis based on blinded independent central review. Significant PFS benefit with lazertinib was consistently observed across predefined subgroups, including patients with BM (HR, 0.28; 95% CI, 0.15 to 0.53) and those with L858R mutations (HR, 0.36; 95% CI, 0.20 to 0.63). Lazertinib safety data were consistent with its previously reported safety profile. Common adverse events (AEs) in both groups included rash, pruritus, and diarrhoea. Numerically fewer severe AEs and severe treatment–related AEs occurred with lazertinib than gefitinib. Conclusion Consistent with results for the overall LASER301 population, this analysis showed significant PFS benefit with lazertinib versus gefitinib with comparable safety in Korean patients with untreated EGFRm NSCLC, supporting lazertinib as a new potential treatment option for this patient population.
