Background and Objectives: The Valsalva test, although commonly utilized to assess the Eustachian tube function, is limited by drawbacks such as inconsistent pressure increases in the nasal cavity. Thus we introduced the “Popper test,” a tympanic membrane inflation test using the automatic middle ear inflation device known as middle ear inflation device (MEID), to explore its viability as an alternative to the Valsalva test.Subjects and Method We sampled 80 ears from patients between June 1, 2023, and August 1, 2023. Each patient underwent both the Valsalva and Popper tests using the MEID. Participants were divided into three categories: the “unable” group (patients who could not follow the Valsalva maneuver) and the “successful” and “unsuccessful” groups (patients whose attempts at the Valsalva or Popper tests either successed or failed). Success or failure was determined using an otoscope to assess the bulging of the tympanic membrane. Results: Of the 68 ears with normal middle ear pressure, 30.9% (21 ears) showed an inability to perform the Valsalva test, 45.6% (31 ears) successfully inflated the tympanic membrane via the Valsalva test, and 23.5% (16 ears) failed. Conversely, the Popper test resulted in an 88.2% (60 ears) success rate for inflating the tympanic membrane, with only 11.8% (8 ears) failing. Conclusion Variability observed in the Valsalva test outcomes may be attributed to individual differences and the instructor’s technique. MEID, as utilized in the Popper test, offers a promising alternative to the Valsalva test, potentially enhancing the reliability by minimizing individual variation. However, the diagnostic performance may be dependent on the properties of the MEID.

Background: The growing number of elderly individuals living alone presents a major social issue, encompassing loneliness, isolation, economic and health challenges, and increased risk of suicide. This study aimed to identify factors associated with suicide risk among elderly individuals living alone in Jeju. Methods: A total of 4,742 participants completed questionnaires to assess their sociodemographic characteristics. Depressive symptoms were evaluated using the Short Form Geriatric Depression Scale-Korean version (sGDS-K), with a cutoff score of eight indicating the presence of depressive symptoms. Suicide risk was assessed using the MiniInternational Neuropsychiatric Interview-Plus. Multivariate logistic regression analysis was performed to identify significant correlates of suicide risk. Results: Multivariate logistic regression analysis identified the following factors as significantly associated with suicide risk: poor subjective health status (odds ratio [OR]=1.590, 95% confidence interval [CI]: 1.137-2.224), current drinking (OR=1.511, 95% CI: 1.119-2.042), hypertension (OR=1.419, 95% CI: 1.133-1.778), and sGDS scores ≥8 (OR=4.318, 95% CI: 3.408-5.469). Conclusion This study highlights the importance of intensive mental health services and socioeconomic support in preventing suicide among elderly individuals living alone. Targeted interventions should focus on those who have poor subjective health status, are current drinkers, have hypertension, or exhibit depressive symptoms.

Purpose: Adjuvant treatment for craniopharyngioma after surgery is controversial. Adjuvant external beam radiation therapy (EBRT) can increase the risk of long-term sequelae. Stereotactic radiosurgery (SRS) is used to reduce treatment-related toxicity.In this study, we compared the treatment outcomes and toxicities of adjuvant therapies for craniopharyngioma. Materials and Methods: We analyzed patients who underwent craniopharyngioma tumor removal between 2000 and 2017. Of the 153 patients, 27 and 20 received adjuvant fractionated EBRT and SRS, respectively. We compared the local control (LC), progression-free survival (PFS), and overall survival between groups that received adjuvant fractionated EBRT, SRS, and surveillance. Results: The median follow-up period was 77.7 months. For SRS and surveillance, the 10-year LC was 57.2% and 57.4%, respectively. No local progression was observed after adjuvant fractionated EBRT. One patient in the adjuvant fractionated EBRT group died owing to glioma 94 months after receiving radiotherapy (10-year PFS: 80%). The 10-year PFS was 43.6% and 50.7% in the SRS and surveillance groups, respectively. The treatment outcomes significantly differed according to adjuvant treatment in nongross total resection (GTR) patients. Additional treatment-related toxicity was comparable in the adjuvant fractionated EBRT and other groups. Conclusion Adjuvant fractionated EBRT could be effective in controlling local failure, especially in patients with non-GTR, while maintaining acceptable treatment-related toxicity.

The prevalence of postpartum depression (PPD) in Asia is reported to range from 13.53% to 22.31%. However, there remains a gap in the identification of PPD, particularly regarding cultural cutoff points. Therefore, the purpose of this scoping review was to determine the prevalence and associated factors of PPD in Eastern, South-eastern, Western, and Southern Asian countries and analyze the cutoff points of the Edinburgh Postnatal Depression Scale (EPDS) used across these countries. Following Arksey and O'Malley’s five-step scoping review framework, the population was defined as mothers, the concept as the EPDS, and the context as the Asian region. A literature search was conducted using PubMed, Embase, CINAHL, PsycINFO, and Web of Science. The data analysis focused on demographic characteristics, EPDS cutoffs and features, PPD prevalence, and its associated factors. Nineteen studies were selected. Most countries used translated versions of the EPDS with demonstrated reliability and validity. The cutoff scores varied, with most using scores of 10 or higher. The prevalence of PPD ranged from 5.1% to 78.7%. Key associated factors for PPD included cultural factors such as relationships with in-laws and preferences for the newborn’s sex. To improve the accuracy of PPD screening in Asia, the EPDS should be used consistently, and appropriate cutoff criteria must be established. In addition, prevention strategies and programs that reflect the cultural characteristics and social context of Asia need to be developed for the early detection and prevention of PPD.

Purpose: Since 1995, the Korean Gastric Cancer Association (KGCA) has been periodically conducting nationwide surveys on patients with surgically treated gastric cancer. This study details the results of the survey conducted in 2023. Materials and Methods: The survey was conducted from March to December 2024 using a standardized case report form. Data were collected on 86 items, including patient demographics, tumor characteristics, surgical procedures, and surgical outcomes. The results of the 2023 survey were compared with those of previous surveys. Results: Data from 12,751 cases were collected from 66 institutions. The mean patient age was 64.6 years, and the proportion of patients aged ≥71 years increased from 9.1% in 1995 to 31.7% in 2023. The proportion of upper-third tumors slightly decreased to 16.8% compared to 20.9% in 2019. Early gastric cancer accounted for 63.1% of cases in 2023.Regarding operative procedures, a totally laparoscopic approach was most frequently applied (63.2%) in 2023, while robotic gastrectomy steadily increased to 9.5% from 2.1% in 2014.The most common anastomotic method was the Billroth II procedure (48.8%) after distal gastrectomy and double-tract reconstruction (51.9%) after proximal gastrectomy in 2023.However, the proportion of esophago-gastrostomy with anti-reflux procedures increased to 30.9%. The rates of post-operative mortality and overall complications were 1.0% and 15.3%, respectively. Conclusions The results of the 2023 nationwide survey demonstrate the current status of gastric cancer treatment in Korea. This information will provide a basis for future gastric cancer research.
