Purpose: This study aimed to identify the relationship between job complexity, infection prevention environment, and nursing intention for patients with emerging infectious diseases, with a focus on the mediating effect of job crafting in hospitals dedicated to coronavirus disease 2019 (COVID-19). Methods: The study surveyed 202 nurses with at least 3 months of work experience who encountered COVID-19 patients at a dedicated COVID-19 hospital. The collected data were analyzed using IBM SPSS/WIN 25.0, and the mediating effect was analyzed through the SPSS PROCESS macro, using regression analysis. Results: It was demonstrated that job crafting fully mediated the relationship between job complexity and nursing intention for patients with emerging infectious diseases. Furthermore, this study showed that job crafting partially mediated the relationship between infection prevention environment and nursing intention for patients with emerging infectious diseases. Conclusion It was confirmed that job crafting of nurses in a hospital dedicated to COVID-19 was an important mediating factor in their nursing intention for patients with emerging infectious diseases, and this finding is expected to support efforts to further improve nursing intention for patients with emerging infectious diseases.

A 24 year old man visited our hospital, because an intrapulmonary foreign body had been found incidentally. Simple chest X-ray showed a 5 cm sized foreign body of metallic density, and chest CT confirmed the foreign body, which was like a sewing needle, in the left upper lobe. We performed a simple extraction of the foreign body using VATS (Video Assisted Thoracic Surgery). After the operation, the patient was discharged without any complications.

Sacroiliac (SI) joint pain can result from degeneration, infection, malignancy, and trauma. Patients with metastatic bone pain who do not respond to conventional treatment may need more aggressive neuroinvasive approaches. Recently, pulsed radiofrequency (PRF) neuromodulation has emerged as a promising treatment alternative for refractory cases of SI joint pain. Nevertheless, there is no report on the treatment of pain arising from SI joint metastases with PRF. We are reporting about a 63-year-old woman suffering from buttock pain due to breast cancer metastases in the SI joint. We treated this patient with PRF neuromodulation of the L4-S3 primary dorsal rami and lateral branches using a rotating curved needle technique. The patient tolerated the procedures well, without any complications. She experienced about 70% reduction in pain, and pain relief was sustained for 10 months. This result suggests that PRF neuromodulation is a safe, effective treatment for pain from SI joint metastases.

The incidence of a primary central nervous system (CNS) lymphoma in western countries is about 1% of all the intracranial tumors and has increased 2.2% over the last decade. A similar pattern of increased frequency is observed in Korea. Although most CNS lymphomas in western countries are high grade tumors carrying poor prognosis, the clinicopathologic features of the Korean CNS lymphoma have not been well studied. We report clinicopathological features of 18 cases of histologically proven primary brain lymphoma. The mean age of the patients was 50 years and there was no sex difference. The clinical and radiological characteristics included multiple site of occurrence, infrequent extracranial spread, and frequent seeding via cerebrospinal fluid. No patients were immune-compromised host. Of 18 cases, 15 cases were of B-lineage and 2 cases were of T-lineage. According to REAL classification, there were 12 cases of diffuse large B cell lymphoma, two cases of B cell lymphomas of small lymphoid cell, and two cases of peripheral T cell lymphoma, unspecified. The remaining subtypes were not subclassified because of inadequate material. Pleomorphic cytologic features and necrosis of varying extent were frequent in the cases of diffuse large B-cell lymphoma. These results suggest that overall clinicopathologic features of primary malignant lymphomas of the central nervous system in Korea are similar to those of western countries.

PURPOSE: Effectiveness of the performance of bystander cardiopulmonary resuscitation (CPR) has a decisive impact on the outcomes for out-of-hospital cardiac arrest patients who receive it. After initial CPR education, CPR performance for those trained declines over time. Public education in CPR is commonly recommended to be repeated every 2 years. In this study, we evaluated the willingness of those who have been CPR trained to perform CPR as impacted by their training experience. METHODS: The staff of a small firm received 2 hours of primary CPR education. Two years later, their CPR training was repeated in an identical manner. Participants answered a questionnaire regarding their willingness to perform bystander CPR. Those who answered that they wouldn't perform bystander CPR were asked to select their reason. We also inquired about what they viewed as the most difficult phase of CPR performance, and collected their opinions about the overall necessity and appropriate time period for re-education. RESULTS: Those who answered 'definitely yes' to 'willingness to perform to CPR' increased from 36.6% before primary CPR education to 74.2% afterward. But 2 years later and before re-education, only 30.1% answered 'definitely yes' to 'willingness to perform CPR'. Meanwhile, 41.2% and 29.4% answered that 'fear of legal liability' and 'fear of poor knowledge/performance' were the reasons why they would not perform bystander CPR. Ventilation was the most difficult stage in CPR identified by 34% of the participants, and 18.4% answered that chest compression was the most difficult stage in CPR. 93.6% answered that they should receive CPR re-education. CONCLUSION: The willingness to perform bystander CPR declined significantly after 2 years. Therefore routine public re-education for bystander CPR is necessary.

Twenty six year old man was struck by a bus, and sustained multiple rib fracture, sternal fracture, right scapular fracture, left subclavian arterial obstruction, and traumatic tracheoesophageal fistula. Diastolic murmur was heard, and echocardiography revealed a markedly regurgitant aortic valve and suspected vegetation. After establishing cardiopulmonary bypass and cardioplegic arrest, the aorta was opened. The left and right coronary cusp were ruptured 10mm, and 7mm, respectively. The leaflets were sutured with running 5-0 Prolene sutures. After the repair of the ruptured valve cusp, the valve was coapted well. He was discharged with excellent outcome on postoperative day 14.

Pulmonary artery sling is a rare congenital condition in which the left pulmonary artery arises from the right pulmonary artery forming a sling around the trachea. This causes tracheal compression with the resulting respiratory symptoms. Most cases are associated with cardiovascular and tracheobronchial abnormalities. Some cases present incidentally without respiratory symptoms in adolescents and adults. We report a case with double left aberrant pulmonary artery associated with multiorgan anomalies which was incidentally found.

OBJECTIVES: This study investigated the effects of a hydrofluoric acid (HA; solution of hydrogen fluoride [HF] in water)-based smart etching (SE) solution at an elevated temperature on yttria-stabilized tetragonal zirconia polycrystal (Y-TZP) ceramics in terms of bond strength and morphological changes.MATERIALS AND METHODS: Eighty sintered Y-TZP specimens were prepared for shear bond strength (SBS) testing. The bonding surface of the Y-TZP specimens was treated with 37% phosphoric acid etching at 20°C–25°C, 4% HA etching at 20°C–25°C, or HA-based SE at 70°C–80°C. In all groups, zirconia primers were applied to the bonding surface of Y-TZP. For each group, 2 types of resin cement (with or without methacryloyloxydecyl dihydrogen phosphate [MDP]) were used. SBS testing was performed. Topographic changes of the etched Y-TZP surface were analyzed using scanning electron microscopy and atomic force microscopy. The results were analyzed and compared using 2-way analysis of variance.RESULTS: Regardless of the type of resin cement, the highest bond strength was measured in the SE group, with significant differences compared to the other groups (p < 0.05). In all groups, MDP-containing resin cement yielded significantly higher bond strength values than MDP-free resin cement (p < 0.05). It was also shown that the Y-TZP surface was etched by the SE solution, causing a large change in the surface topography.CONCLUSIONS: Bond strength significantly improved when a heated HA-based SE solution was applied to the Y-TZP surface, and the etched Y-TZP surface was more irregular and had higher surface roughness.
