Objectives: This study was conducted to examine the obstacles in the use of healthcare from the perspective of family caregivers based on their experience of mental healthcare services and to identify practical recommendations according to the family’s needs. Methods: A focus group interview was conducted with 59 family caregivers of patients with mental disorders. They were asked about the first moment when they took the patient to a psychiatric hospital, their feelings, and experiences during the treatment, relapse or readmission, access to healthcare and obstacles. The results were analyzed in a three-step procedure using grounded theory analysis. Results: The results showed that the social prejudice and stigma toward mental disorders experienced by the family caregivers hindered the initial treatment approach. Discrimination and disadvantages in healthcare, and poor access to community mental healthcare services, lowered the reliability of institutions and services. A decrease in the sense of healing due to distrust in the treatment and disruption of family life can lead to a vicious circle that affects the continuity of treatment and could result in issues such as the stopping of treatment or difficulty in accessing treatment in case of relapse. Conclusion Based on these results, policy tasks were proposed to improve accessibility to mental health services according to the needs of the patient’s family.

Objectives: The incidence of adenocarcinomas of the esophagogastric junction (EGJ) and cardia has been gradually increasing in the East. Cancers of the EGJ and gastric cardia have poor prognoses. This study aimed to investigate lymph node metastasis (LNM) rates, their predictive factors, and determine the long-term outcomes of patients with Siewert type II/III early gastric cancer (EGC). Methods: Between January 2014 and June 2022, a total of 573 patients with gastric cancer, including 130 with Siewert type II/III EGC, underwent total gastrectomies at the Kosin University Gospel Hospital. Factors associated with LNM were analyzed using a logistic regression model. Results: Of the 130 patients with Siewert type II/III EGC, 10 (7.7%) demonstrated LNM (LNM-positive group). Macroscopically elevated lesions (I+IIa) (60.0% vs. 16.7%; p=0.009) and lymphovascular invasion (70.0% vs. 5.8%; p<0.001) were more common and the depth of invasion was deeper (p=0.003) in the LNM-positive patients than in the LNMnegative group. Multivariate analysis showed that macroscopically elevated lesions (odds ratio [OR], 19.48; 95% confidence interval [CI], 1.93–197.11; p=0.012) and lymphovascular invasion (OR, 52.63; 95% CI, 5.26–526.51; p=0.001) were associated with LNM. Kaplan–Meier analysis revealed that the 5-year overall and disease-specific survival rates of patients with Siewert type II/III EGC were 90.0% and 98.9%, respectively. During a median follow-up period of 49 months (range, 12–122 months), one patient (0.8%) died owing to gastric cancer recurrence. Conclusions Patients with Siewert type II/III EGC showed favorable long-term outcomes. Macroscopically elevated lesions and lymphovascular invasion are associated with LNM.

Purpose: This study investigated the effects of nursing unit managers' authentic, transformational, and transactional leadership styles on positive psychological capital and turnover intention in advanced beginner-stage nurses (ABNs). Methods: The study included 157 nurses with clinical experience ranging form more than one year to less than 3 years in three general hospitals. Data analysis was conducted using the SPSS/WINdows software version 26.0. Results: Authentic, transformational, and transactional leadership styles of nursing unit managers increased the positive psychological capital of ABNs, thereby lowering their turnover intention. Additionally, the turnover intention of ABNs was negatively correlated with the authentic, transformational, and transactional leadership styles of a nursing unit manager and positive psychological capital. Positive psychological capital showed a mediating effect in the relationship between authentic, transformational, and transactional leadership styles of nursing unit manager and turnover intention of ABNs. Conclusion To reduce ABNs turnover, medical institutions and nursing organizations should focus on enhancing nursing unit managers’ transformational and authentic leadership styles. Moreover, as transactional leadership has been found to decrease the turnover intention among ABNs, nursing unit managers should carefully consider their responsibilities and resources allocation to provide conditional compensation support to nurses.

Background/Aims: Although endoscopic ultrasound (EUS)-guided fine needle aspiration (FNA) and fine needle biopsy (FNB) are widely used for tissue acquisition of pancreatic solid mass, the optimal strategy of this procedure has not been established yet. The aim of this nationwide study was to investigate the current practice patterns of EUS-FNA/FNB for pancreatic solid mass in Korea. Methods: The Policy-Quality Management of the Korean Pancreatobiliary Association (KPBA) developed a questionnaire containing 22 questions. An electronic survey consisting of the questionnaire was distributed by e-mail to members registered to the KPBA. Results: A total of 101 respondents completed the survey. Eighty respondents (79.2%) performed preoperative EUS-FNA/FNB for operable pancreatic solid mass. Acquire needles (60.4%) were used the most, followed by ProCore needles (47.5%). In terms of need size, most respondents (>80%) preferred 22-gauge needles regardless of the location of the mass. Negative suction with a 10-mL syringe (71.3%) as sampling technique was followed by stylet slow-pull (41.6%). More than three needle passes for EUS-FNA/FNB was performed by most respondents (>80%). The frequency of requiring repeated procedure was significantly higher in respondents with a low individual volume (<5 per month, p=0.001). Prophylactic antibiotics were routinely used in 39 respondents (38.6%); rapid on-site pathologic evaluation was used in 6.1%. Conclusions According to this survey, practices of EUS-FNA/FNB for pancreatic solid mass varied substantially, some of which differed considerably from the recommendations present in existing guidelines. These results suggest that the development of evidence-based quality guidelines fitting Korean clinical practice is needed to establish the optimal strategy for this procedure.

In recent years, the rise of minimally invasive surgery has driven the development of surgical devices. Indocyanine green (ICG) fluorescence imaging is receiving increased attention in colorectal surgery for improved intraoperative visualization and decision-making. ICG, approved by the U.S. Food and Drug Administration in 1959, rapidly binds to plasma proteins and is primarily intravascular. ICG absorption of near-infrared light (750–800 nm) and emission as fluorescence (830 nm) when bound to tissue proteins enhances deep tissue visualization. Applications include assessing anastomotic perfusion, identifying sentinel lymph nodes, and detecting colorectal cancer metastasis. However, standardized protocols and research on clinical outcomes remain limited. This study explores ICG’s role, advantages, disadvantages, and potential clinical impact in colorectal surgery.

Background/Aims: To compare the performance of the Liver Imaging Reporting and Data System (LI-RADS) v2018 and Korean Liver Cancer Association-National Cancer Center (KLCANCC) 2018 criteria for diagnosing hepatocellular carcinoma (HCC) using magnetic resonance imaging (MRI) with hepatobiliary agent (HBA). Methods: We searched the MEDLINE and EMBASE for studies from January 1, 2018, to October 20, 2021, that compared the diagnostic performance of two imaging criteria on HBA-MRI. A bivariate random-effects model was fitted to calculate the per-observation sensitivity and specificity, and the estimates of paired data were compared. Subgroup analysis was performed based on the observation size. Meta-regression analysis was also performed for study heterogeneity. Results: Of the six studies included, the pooled sensitivity of the definite HCC category of the KLCA-NCC criteria (82%; 95% confidence interval [CI], 74% to 90%; I 2 =84%) was higher than that of LR-5 of LI-RADS v2018 (65%; 95% CI, 52% to 77%; I 2 =96%) for diagnosing HCC (p<0.001), while the specificity was lower for KLCA-NCC criteria (87%; 95% CI, 84% to 91%; I 2 =0%) than LI-RADS v2018 (93%; 95% CI, 91% to 96%; I 2 =0%) (p=0.017). For observations sized ≥20 mm, the sensitivity was higher for KLCA-NCC 2018 than for LI-RADS v2018 (84% vs 74%, p=0.012), with no significant difference in specificity (81% vs 85%, p=0.451). The reference standard was a significant factor contributing to the heterogeneity of sensitivities. Conclusions The definite HCC category of KLCA-NCC 2018 provided a higher sensitivity and lower specificity than the LR-5 of LI-RADS v2018 for diagnosing HCC using MRI with HBA.

Background: Current evidence support that the gut microbiota plays a potential role in obesity. Bariatric surgery can reduce excess weight and decrease the risk of life-threatening weight-related health problems and may also influence gut microbiota. In this study, we aimed to investigate the changes in gut microbiota before and after bariatric surgery and evaluate the association of the gut microbial shift and altered body mass index (BMI) after bariatric surgery. Methods: Between January 2019 and July 2020, stools from 58 patients scheduled for bariatric surgery were collected. Six months after bariatric surgery, stools from 22 of these patients were re-collected, and the changes in gut microbiota before and after bariatric surgery were evaluated. In addition, the differences in gut microbiota between patients with severe obesity (BMI >35 kg/m2, n=42) and healthy volunteers with normal BMI (18.8 to 22.8 kg/m2, n=41) were investigated. Results: The gut microbiota of patients who underwent bariatric surgery showed increased α-diversity and differed β-diversity compared with those before surgery. Interestingly, Blautia was decreased and Bacteriodes was increased at the genus level after bariatric surgery. Further, the Blautia/Bacteroides ratio showed a positive correlation with BMI. To validate these results, we compared the gut microbiota from severely obese patients with high BMI with those from healthy volunteers and demonstrated that the Blautia/Bacteroides ratio correlated positively with BMI. Conclusion In the gut microbial analysis of patients who underwent bariatric surgery, we presented that the Blautia/Bacteroides ratio had changed after bariatric surgery and showed a positive correlation with BMI.

Purpose: Long-term oncologic differences in outcome between groups of patients with Lynch syndrome (LS) colorectal cancer (CRC) and sporadic CRC with microsatellite instability-high (MSI-H) are the focus of investigation in the current study. Methods: Patients registered in the Korean Hereditary Tumor Registry and 2 tertiary referral hospitals treated for stage I– III CRC between 2005 and 2015 were retrospectively analyzed. Detection for both groups was performed using pedigree, microsatellite instability, and mismatch repair (MMR) gene testing. Multivariate analyses for overall survival (OS) and disease-free survival (DFS) were conducted. Results: Cases of LS (n = 77) and sporadic CRC with MSI-H (n = 96) were identified. LS CRC patients were younger in age and displayed tumor sidedness, typically involving left-sided colon and rectum, compared to patients with sporadic CRC with MSI-H. OS and DFS were lower for LS CRC relative to CRC with MSI-H (OS, 72.7% vs. 93.8%, P = 0.001; DFS, 71.4% vs. 88.5%, P = 0.001). In multivariate analyses, tumor sidedness, stage, and chemotherapy were independent factors for OS and DFS. LS CRC was a prognostic factor for poorer OS (hazard ratio, 2.740; 95% confidence interval, 1.003–7.487; P = 0.049), but not DFS. Conclusion Our findings indicate that LS CRC is associated with poorer outcomes compared to sporadic CRC with MSI-H, presenting distinct clinical features. In view of the current lack of knowledge on genetic and molecular mechanisms, appropriate management taking into consideration the difficulty of identification of CRC with hypermutable tumors harboring heterogeneity is essential.
