Background: Although the concepts of a family physician and regular doctor are interchangeably used in the general population, they differ in various aspects of healthcare services. We investigated the prevalence of having a family physician/regular doctor and its association with healthcare utilization behaviors among community-dwelling adults. Methods: A cross-sectional survey was conducted among students and employees at a university from October 2018 to February 2019. Information was collected on the presence of a family physician/regular doctor, healthcare facilities most frequently visited, annual healthcare visit frequencies, and out-of-pocket medical expenses. Associated factors with having a family physician/regular doctor were analyzed using multivariable logistic regression adjusting for demographic characteristics, health-related variables, and healthcare utilization behaviors. Results: A total of 5,890 individuals were included, of which 15% had family physicians/regular doctors (students 12.6%, employees 21.3%). Factors significantly associated with having a family physician/regular doctor were older age, higher income level, and managing chronic diseases.Individuals having a family physician/regular doctor were more likely to use large/tertiary hospitals rather than primary care clinics, use healthcare services more frequently, and have higher medical expenditures. Conclusion The prevalence of having a regular doctor was low in community-dwelling adults, with a higher prevalence among high-income groups and a tendency to visit large/tertiary hospital specialists for a regular doctor. Our results indicate that many community-dwelling individuals lack proper awareness of the roles of family physicians in providing comprehensive and continuous healthcare, emphasizing urgent needs to enhance public awareness of the concept of family physicians based on primary care.

Hemangiopericytoma is a relatively uncommon vascular tumor. It was first described by Stout and Murray in 1942. Here, we report a case of a primary prostatic hemangiopericytoma, which has been reported approximately <10 cases. This may be the first case of a prostatic hemangiopericytoma in Korea. A 35-year-old male patient presented with an episode of dysuria and perineal discomfort over the past 3 months. The radiological and histological features indicated a malignant hemangiopericytoma. Systemic chemotherapy was selected as the primary treatment. After 5 cycles of chemotherapy, the size of masses of the prostate and lung decreased. Four months after then, the patient died from hemoptysis.

Background: The Fourth Industrial Revolution highlights the importance of artificial intelligence (AI) and digital literacy in dentalhygiene education. However, research on students’ attitudes toward AI and their digital literacy levels is limited. Therefore, this study investigated the attitudes of dental hygiene students toward AI and digital literacy levels. Methods: In total, 167 dental hygiene students in Baekseok University participated in the study and provided informed consent.The survey tool included general characteristics, smartphone usage patterns, attitudes toward AI, and digital literacy levels.Attitudes toward AI and digital literacy based on general characteristics and smart device usage were analyzed using t-tests and one-way ANOVA. Correlations among attitudes toward AI, digital literacy awareness, and digital literacy behaviors were analyzed using Pearson’s correlation analysis. The impact of AI attitudes and digital literacy awareness on digital literacy behavior was examined using linear regression analysis. Results: Students with higher interest in their major had more positive attitudes toward AI, and those with higher smart deviceusage showed increased AI attitudes and digital literacy (p＜0.05). Simple frequency or duration of smartphone use did not affect digital literacy, but students who perceived their smart device usage positively and believed that they used smart devices effectively in their studies exhibited higher levels of digital literacy (p＜0.05). A positive attitude toward AI is associated with higher levels of digital literacy (p＜0.05). Digital literacy awareness and attitudes toward AI influenced digital literacy behavior (p＜0.05). Conclusion These results suggest that the qualified utilization and application of digital devices in dental hygiene education areimportant. Improving the educational curriculum is necessary; as a result, digital technology can be effectively utilized, and various educational programs should be introduced to enhance digital literacy.

Diisocyanate (DI) is the most common cause of occupational asthma (OA) in Korea. Mannose-binding lectin (MBL) initiates the lectin complement activation pathway following oxidative stress and plays an important role in the regulation of inflammatory processes. To determine whether there is a genetic association between MBL2 polymorphisms and DI-OA, 99 patients with DI-OA, 99 asymptomatic exposed controls (AECs) and 144 unexposed normal controls were enrolled in this study. Three polymorphisms (-554 G>C, - 431A>C and - 225 G>C) in the MBL2 promoter were genotyped, and serum MBL levels were determined by enzyme-linked immunosorbent assay. Functional variabilities in the promoter polymorphisms were analyzed by a luciferase reporter assay and electrophoretic mobility shift assay (EMSA). A significantly higher frequency of haplotype (ht) 2 [CAG] was noted in the DI-OA group compared with the AEC group (P=0.044). The patients with DI-OA carrying ht2 [CAG] had significantly lower PC20 methacholine levels (P<0.001) than the non-carriers. The serum MBL levels were significantly higher in the DI-exposed subjects (both the DI-OA patients and AECs) carrying ht1 [GAG] (P=0.028). Luciferase activity was significantly enhanced in ht1 [GAG] compared with ht2 [CAG] in human hepatocarcinoma cells (Hep3B) (P=0.002). The EMSA showed that a - 554G probe produced a specific shifted band compared with the - 554C probe. These findings suggest that decreased serum MBL levels due to polymorphisms of the MBL2 gene may increase susceptibility to the development of DI-OA in DI-exposed individuals.

Several studies have previously reported that exposure to stress provokes behavioral changes, including antinociception, in rodents. In the present study, we studied the effect of acute cold-water (4°C) swimming stress (CWSS) on nociception and the possible changes in several signal molecules in male ICR mice.Here, we show that 3 min of CWSS was sufficient to produce antinociception in tailflick, hot-plate, von-Frey, writhing, and formalin-induced pain models. Significantly, CWSS strongly reduced nociceptive behavior in the first phase, but not in the second phase, of the formalin-induced pain model. We further examined some signal molecules' expressions in the dorsal root ganglia (DRG) and spinal cord to delineate the possible molecular mechanism involved in the antinociceptive effect under CWSS.CWSS reduced p-ERK, p-AMPKα1, p-AMPKα2, p-Tyk2, and p-STAT3 expression both in the spinal cord and DRG. However, the phosphorylation of mTOR was activated after CWSS in the spinal cord and DRG. Moreover, p-JNK and p-CREB activation were significantly increased by CWSS in the spinal cord, whereas CWSS alleviated JNK and CREB phosphorylation levels in DRG. Our results suggest that the antinociception induced by CWSS may be mediated by several molecules, such as ERK, JNK, CREB, AMPKα1, AMPKα2, mTOR, Tyk2, and STAT3 located in the spinal cord and DRG.
