The aim of this study was to examine the validity and reliability of the Korean version of the PTSD scale (K-PTSD) for measuring attitudes and knowledge of PTSD. Methods: A cross-sectional study design was used. The K-PTSD scale consisted of 8 items for attitudes, 8 items for general knowledge of PTSD, and 3 items for knowledge of PTSD treatment; 211 nursing students and paramedic students participated. Content validity, item analysis, and factor analysis were used to examine the construct validity. Criterion validity was tested by using educational experience with PTSD as a criterion. Cronbach's α was used to identify internal consistency reliability in the attitude scale. Results: Construct validity of the K-PTSD was verified by exploratory factor analysis, with factor loadings for attitude ranging from .59 to .84. Criterion validity in comparing knowledge of PTSD (t=2.02, p=.044) and PTSD treatment (t=3.19, p=.022) showed a significant difference according to PTSD educational experience. Cronbach's α for the attitude scale was .79 and .59. Conclusion: The findings suggest that the K-PTSD is a valid and reliable tool that can measure attitudes and knowledge of PTSD among nursing and paramedic students. However, further study is needed to retest the verification of this scale with more diverse participants.

Purpose: This study aimed to identify attitude and knowledge level on post-traumatic stress disorder (PTSD) among nursing and paramedic students. Methods: A questionnaire survey was conducted from December 1st to 20th in 2019. A total of 210 students participated from two universities in Korea. Data were analyzed using descriptive statistics, t-tests and one-way analysis of variance. Results: Students were positive about the government's spending on PTSD treatment (91.4%), and professional training (92.4%). PTSD patients were considered to be more dangerous (68.1%) and violent (42.4%) than the general population. There were no significant differences in attitude and general knowledge on PTSD between nursing and paramedic students. However, general knowledge on PTSD differed according to education experience on PTSD (t=2.04, p=.043). Knowledge scores for PTSD treatment differed significantly according to the academic major (t=2.02, p=.044), and education experience on PTSD (t=2.87, p=.005). Conclusions The results of this study indicate nursing and paramedic students lack knowledge on PTSD. Therefore, developing curriculum regarding PTSD-related contents in undergraduate and continuing education in both departments is needed to provide better quality health care to people with PTSD.

Lymphomatous involvement of the gallbladder is rarely identified and manifests mostly as a local involvement of disseminated disease. There have been reported only about 20 primary malignant lymphomas of the gallbladder without involvement of other sites. A 63-year-old woman presented with jaundice, epigastric pain, and weight olss of two months duration. There was no systemic lymphadenopathy elsewhere. Abdominal computed tomograph revealed a focal thickening of the gallbladder wall. The removed gallbladder contained a well circumscribed, 5x3 cm-sized, slightly elevated firm area with accentuated mucosal papillary excrescences near the neck protion. The lesion involved whole thickness of the wall, and was made up of diffuse atypical lymphoid cell infiltrates of variable size accompanying plasmacytoid differentiation in areas. Some large tumor cells were pleomorphic and contained prominent nucleoli. To our knowledge, this is the first case of primary malignant lymphoma of the gallbladder in Korean literature.

Purpose: This study aimed to assess exposure to traumatic events, knowledge and attitudes concerning post-traumatic stress disorder (PTSD) and the level of resilience among nurses and paramedics working in emergency departments. Methods: Data were collected from May 22 to June 12, 2022, using a self-administered survey questionnaire. The participants comprised 135 nurses and 80 paramedics working in emergency departments. The collected data were analyzed with descriptive statistics, a t-test, and an analysis of variance with Scheffé’s test. Results: Compared with emergency room nurses, paramedics were more positive about the government’s spending on job opportunities for people with PTSD. There were no significant differences in attitude regarding government strategies and people with PTSD between nurses and paramedics. Paramedics had higher scores on the effective treatment for PTSD, while emergency room nurses showed higher scores on effective psychotherapy. General knowledge of PTSD differed according to sex (t=-2.33, p=.021) and education level (F=3.21, p=.042). Resilience scores differed significantly according to sex (t=2.02, p=.045), education level (F=4.10, p=.018), self-reported economic state (F=10.34, p<.001), and self-reported health (F=11.57, p<.001). Conclusion The findings support that emergency department nurses and paramedics are in need of self-care programs to support their mental health and indicate that intervention programs should be developed to enhance resilience in emergency department professionals.

Purpose: This study aimed to investigate the knowledge, opinions, competence, and barriers of nurses providing trauma-informed care (TIC) to children in hospitals. Methods: Data were collected from 198 nurses nationwide using the TIC Provider Survey developed by the Center for Pediatric Traumatic Stress in July, 2024. Descriptive statistics, t tests, and one-way ANOVA were conducted using the IBM SPSS Statistics software (ver. 23.0, IBM Corp.). Results: Of the 13 items assessing knowledge of TIC, seven had a correct response rate of over 90%. However, the correct response rate for these three items were less than 30%. Regarding opinions on the TIC, more than 90% of participants agreed with five of the seven items. In self-rated competence in providing TIC, they were not competent in responding to a child’s (or parent’s) questions about whether the child is going to die or understanding how traumatic stress may present differently according to developmental stages. The major barriers to providing TIC were time constraints, lack of training, and organizational support. Items with relatively low performance rates were ‘teach parents what to say to their child after a difficult/sick/scary experience, and teach child or parents the specific ways to cope with unpleasant experiences’. Conclusion This study suggests that it can contribute to the development of specific guidelines for nurses to effectively apply TIC in pediatric and family nursing practice, emphasizing the need for educational programs to support this implementation.

The cellular cardiac effects of protamine, the cationic polypeptide employed to reverse heparin anticoagulation, were examined in vitro to define its mechanisms of action. Isometric contractile force and action potential (AP) characteristics after rest (RS) and at frequencies up to 3 Hz were recorded in guinea pig ventricular papillary muscle. The actions of protamine (10-300 ug/ ml) were compared to those of heparin (10, 30 units/ml), and to heparin (10 units/ml) neutralized with equivalent (100 ug/ml) or excess (200 ug/ml) protamine. The effects of protamine were also examined using muscle rapid cooling contractures (RCCs to assess intracellular Ca(z+) stores). Protamine (100-300 ug/ml) depressed contractions by 35-65% at 3 Hz, whereas contractions were enhanced 150-500% at lower rates (RS-0.5 Hz), with a concommitant rise in resting force. Protamine caused a resting depolarization from -84 to -72 mV and depressed AP amplitude. In contrast, heparin minimally altered contractile or AP characteristics. In 26 mM K(+)-solution with 0.1 uM isoproterenol, 30-300 ug/ml protamine caused dose-dependent depression of late peaking force development and slow AP prolongation. After 15 minutes rest, when RCCs were not normally elicited, rest RCCs became prominent in 100-300 ug/ml protamine. Effects of heparin with 100 ug/ml excess protamine were similar to those of 100 ug/ml protamine alone. In conclusion the loss of normal force-frequency relation, partial depolarization, rise in resting tension, and appearance of rested state RCCs suggest that unbound protamine can lead to excess intracellular Ca(2+), mediated by an alteration in memebrane ionic conductances.

PURPOSE: We report seven cases of pancreas transplantation, first performed in Korea, in the context of postsurgical radiologic studies. MATERIALS AND METHODS: All patients with insulin-dependent diabetes mellitus received transplants from cadevaric(n=6) or living related donor(n=1). Retrospective analysis of 27 US(including 19 Duplex US), two CT, four MRi, and three scintigraphy for these patients was made with surgico-pathological correlation in five cases. RESULT:Of the seven patients, three-month graft survival was five and one-year survival was two. One patient died of abdominal abscess following surgery. US gave the valuable informations regarding the graff swelling, vascular complication, and perigraff fluid collection. RBC bleeding scan was effective of the presence or absence and location of intestinal bleeding. CT was useful in determining the extent and severity of the pancreatitis. MRI gave a little information about functional status of the grafted pancreas. CONCLUSION: The choice of appropriate imaging modalities for postsurgical work up in patients who had pacreas transplantation depends on the clinical conditions of the patients and complications suspected. Further prospective studies appear to be necessary to eatablish the interval and modality choice for early detection of the complication.
