Purpose: The purpose of this study was to explore and assess the experiences of cancer patients and their caregivers who had been admitted to comprehensive nursing care service wards. Methods: Data were collected from 10 patients and 10 caregivers by in-depth interviews. The data were analyzed using content analysis of Downe-Wamboldt. Results: Three categories and seven subcategories were extracted. 1) Realizing institutional limitations of comprehensive nursing care service: ‘Wishing for precise operating systems based on patient severity,’ ‘Anticipating active caregiver participation in treatment process,’ ‘Requiring a countermeasure for safety accidents,’ 2) Professional nursing service which provides relief: ‘Patient-centered professional nursing service,’ ‘Inpatient service that provides relief for patients and caregivers,’ 3) Anticipating continuous use of the service: ‘Inpatient service which users are willing to reuse,’ ‘Wishing for expansion and reinforcement of the service.’ Conclusion Cancer patients and their caregivers experienced institutional limitations while satisfied with professional nursing service and willing to reuse the service. To improve this situation, institutional support such as separate wards for severe patients, measures for active caregiver participation and prevention of safety accidents, and adequate staffing would be helpful for relatively severe level cancer patients and their caregivers.

Purpose: We aimed to identify the genetic causes of hypospadias in children using targeted gene panel sequencing for disorders of sex development (DSD). Materials and Methods: This study included 18 twin boys with hypospadias: seven and two pairs were monozygotic and dizygotic twins, respectively, and six were discordant and three were concordant twins. Targeted gene panel sequencing for 67 known DSD genes was performed. Sequence variants were classified into five different categories, pathogenic, likely pathogenic, variants of uncertain significance, likely benign, and benign, following the American College of Medical Genetics and Genomics Standards and Guidelines. Results: The mean gestational age and birth weight were 35.3±2.0 weeks and 1.96±0.61 kg, respectively, with seven patients being small for gestational age. Hypospadias was present in 12 patients, with posterior type in 33.3% and anterior type in 66.7%.In three families with twins, both siblings had hypospadias. In addition, cryptorchidism was observed in one subject. Surgical correction of hypospadias was performed at a mean age of 22.1 months. Molecular analysis identified 12 different genetic variants, including two pathogenic mutations in the AMH (p.E389*) and SRD5A2 (p.R246Q) genes, found in subjects with hypospadias, respectively. However, only heterozygous mutations were detected. Conclusions This study did not identify a definitive genetic component contributing to the development of hypospadias; however, the findings suggest that intrauterine growth retardation may play a significant role.

Purpose: The use of gallium-68 prostate-specific membrane antigen-11 positron emission tomography/computed tomography (Ga-68 PSMA-11 PET/CT) is becoming increasingly common among men with prostate cancer (PCa). However, it remains uncertain which patients will derive the most benefit, and there is a scarcity of real-world data regarding its impact on altering treatment plans. This study investigated which patients would most benefit from Ga-68 PSMA-11 PET/CT, focusing on detection rates and changes in treatment strategies, drawing from a single-center experience. Materials and Methods: In total, 230 men with PCa who underwent Ga-68 PSMA-11 PET/CT between November 2021 and August 2022 were included in this retrospective study. The patients were classified into 5 groups based on their disease status: group 1, further work-up for high-risk localized PCa; group 2, de novo metastatic PCa; group 3, biochemical recurrence after definitive treatment; group 4, castration-resistant PCa; group 5, others. The positivity rate, positive lesions, predictive value of lymph node metastases, comparison with conventional images, and treatment changes after Ga-68 PSMA-11 PET/CT were analyzed in each group. Results: Of the 230 patients, 40 (17.4%), 20 (8.7%), 77 (33.5%), 76 (33.0%), and 17 (7.4%) were classified into groups 1–5, respectively. Ga-68 PSMA-11 PET/CT showed lesions in 74.8% of patients, and the optimal cutoff value for PSA was 1.99 ng/mL. Lesions not observed on conventional imaging were found in 62 patients (33.2%). In 38 patients (13.5%), treatment was changed due to Ga-68 PSMA-11 PET/CT. Conclusions These real-world data suggest that Ga-68 PSMA-11 PET/CT may be clinically useful for various disease conditions, as substantial stage migration and subsequent treatment changes occur in men with PCa. However, the prognostic impact of this modality remains unclear; thus, a well-designed prospective study is needed to address this issue.

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.

Background: The importance of establishing a regional stroke safety net for the treatment of acute stroke is increasingly emphasized. In this study, we analyzed effectiveness of transferring the suspected acute ischemic stroke (AIS) patients through the 1899-0215 hotline system from 119 ambulances and nearby hospitals. Methods: From July 2015 to July 2022, we analyzed data from 632 suspected acute stroke patients through the hotline. Furthermore, we investigated the proportion of patients in the target population who were eligible for reperfusion therapy and compared cases transferred by 119 emergency services (EMS) with those transferred from nearby hospitals. Results: Six hundred thirty-two suspected acute stroke patients were transferred to our stroke center through the 1899-0215 hotline system. The accuracy of diagnosing acute stroke among transferred patients is 81.0% for 119 EMS and 80.5% for cases transferred from nearby hospitals. Of the 200 patients transferred from hospitals, they were transferred from 47 nearby hospitals with an average transfer distance of 38.2 km and an average transfer time of 65 minutes. Among 291 patients diagnosed with AIS, The onset-to-door time was significantly shorter (p<0.01) for patients transferred by 119 EMS. The proportion of patients who received reperfusion therapy was significantly higher (p<0.01) for those transferred by 119 EMS. Conclusions The hotline service will become a useful tool for establishing a regional stroke network in the Busan area, and its effectiveness will be particularly useful for 119 EMS. Measures are needed in the Busan metropolitan region to ensure the speediness of transferring acute stroke patients between hospitals.

Purpose: This study aimed to develop a model for predicting pathologic extracapsular extension (ECE) and seminal vesicle invasion (SVI) while integrating magnetic resonance imaging-based T-staging (cTMRI, cT1c-cT3b). Materials and Methods: A total of 1,915 who underwent radical prostatectomy between 2006-2016 met the inclusion/exclusion criteria. We performed a multivariate logistic regression analysis as well as Bayesian network (BN) modeling based on possible confounding factors. The BN model was internally validated using 5-fold validation. Results: According to the multivariate logistic regression analysis, initial prostate-specific antigen (iPSA) (β=0.050, p < 0.001), percentage of positive biopsy cores (PPC) (β=0.033, p < 0.001), both lobe involvement on biopsy (β=0.359, p=0.009), Gleason score (β=0.358, p < 0.001), and cTMRI (β=0.259, p < 0.001) were significant factors for ECE. For SVI, iPSA (β=0.037, p < 0.001), PPC (β=0.024, p < 0.001), Gleason score (β=0.753, p < 0.001), and cTMRI (β=0.507, p < 0.001) showed statistical significance. BN models to predict ECE and SVI were also successfully established. The overall area under the receiver operating characteristic curve (AUC)/accuracy of the BN models were 0.76/73.0% and 0.88/89.6% for ECE and SVI, respectively. According to internal comparison between the BN model and Roach formula, BN model had improved AUC values for predicting ECE (0.76 vs. 0.74, p=0.060) and SVI (0.88 vs. 0.84, p < 0.001). Conclusion Two models to predict pathologic ECE and SVI integrating cTMRI were established and installed on a separate website for public access to guide radiation oncologists.

Posterior reversible encephalopathy syndrome is a clinicoradiological syndrome characterized by a unique reversible pattern on imaging and total regression of clinical symptoms and signs. Hypertensive brainstem encephalopathy (HBE), a brainstem variant of posterior reversible encephalopathy syndrome, is rare. In addition, a concomitant occurrence of acute ischemic stroke and HBE is even more rare. We here report three patients with HBE accompanied by acute cerebral infarction detected by brain magnetic resonance imaging and the importance of initial blood pressure control.
