Purpose: To identify the effect of a new leadership type by confirming the effect of clinical nurses' grit and nursing work environment on nursing performance and retention intention with the mediating effect of compassionate rationalism leadership in the process. Methods: A proportional stratified sampling method was used with 45 tertiary general hospitals nationwide as the sampling unit. An online survey targeting nurses who have been working continuously for more than one year was conducted from October 14 to November 9, 2022. The final analysis included 1,256 questionnaires. The correlation between the participants' variables was analyzed using Pearson's correlation coefficients. The mediating effect was confirmed using a regression analysis, and bootstrapping. Results: The compassionate rationalism leadership had a mediating effect on the relationship between grit and nursing performance (F=203.21, p<.001), nursing work environment and nursing performance (F=109.48, p<.001), grit and retention intention (F=149.90, p<.001), and nursing work environment and retention intention (F=25.14, p<.001). Conclusion The compassionate rationalism leadership of nursing managers had a positive effect on nursing performance and retention intention.Therefore, with the development and application of educational programs of compassionate rationalism leadership, it can be used to improve nursing performance and operate an efficient nursing organization.

Monoclonal gammopathy occurs in one-third of the patients with mucosa-associated lymphoid tissue lymphoma (MALT lymphoma). However, monoclonal gammopathy has been rarely reported in Korea. Paraprotenemia accompanying MALT lymphoma is strongly correlated with involvement of the bone marrow, and this involvement leads to the progression of the disease. Here, we present a case of a 66-yr-old man diagnosed with IgM monoclonal gammopathy and stage IV extranodal marginal zone lymphoma of the small intestine, with the involvement of the bone marrow.

Although ischemic colitis is often considered to be a condition occurred in elderly patients or in patients with vascular diseases, it also can occur in younger healthy persons. Some drugs, such as oral contraceptives, may play an important role in the development of ischemic colitis in young women. However, constipation also can play an important role in this condition. We recently experienced a case of reversible ischemic colitis of a young woman, who had been suffered from obstructive type of chronic constipation, after taking a laxative and enema. We report this case with literature review. Proper managements and educations in patients with chronic constipation should be emphasized.

Background: Coronavirus disease 2019 (COVID-19) outbreaks occur in hospitals in many parts of the world. In hospital settings, the possibility of airborne transmission needs to be investigated thoroughly. Materials and Methods: There was a nosocomial outbreak of COVID-19 in a hematologic ward in a tertiary hospital, Seoul, Korea. We found 11 patients and guardians with COVID-19 through vigorous contact tracing and closed-circuit television monitoring. We found one patient who probably had acquired COVID-19 through airborne-transmission. We performed airflow investigation with simulation software, whole-genome sequencing of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Results: Of the nine individuals with COVID-19 who had been in the hematologic ward, six stayed in one multi-patient room (Room 36), and other three stayed in different rooms (Room 1, 34, 35). Guardian in room 35 was close contact to cases in room 36, and patient in room 34 used the shared bathroom for teeth brushing 40 minutes after index used.Airflow simulation revealed that air was spread from the bathroom to the adjacent room 1 while patient in room 1 did not used the shared bathroom. Airflow was associated with poor ventilation in shared bathroom due to dysfunctioning air-exhaust, grill on the door of shared bathroom and the unintended negative pressure of adjacent room. Conclusion Transmission of SARS-CoV-2 in the hematologic ward occurred rapidly in the multi-patient room and shared bathroom settings. In addition, there was a case of possible airborne transmission due to unexpected airflow.

BACKGROUND: The prevalence of HIV drug resistance mutations in drug-naive patients has been shown to differ with geographic origin. The purpose of this study is to assess the prevalence of transmitted antiretroviral drug resistance mutations in drug-naive patients in Korea. METHODS: Genotypic resistance was determined by the use of the Viroseq Genotyping System in 42 antiretroviral treatment naive HIV-infected patients between March 2005 and July 2006. Transmitted drug resistance was estimated according to the IAS-USA 2005 definition, taking into account only major mutations in the protease and all mutations in the reverse transcriptase, including revertant mutations at codon 215. RESULTS: The median age of the patients was 42 years and 37 (88%) were male. The median CD4+T cell count was 136/mm3 and the mean plasma RNA level was 4.98 log copies/mL. Among 42 patients studied, 37 (88%) were newly diagnosed patients. None of the patients were recent seroconverters; 38 patients (90%) were infected with subtype B and 4 patients were infected (10%) with the non-B subtype strains (2 patients with CRF01-AE 1 as CRF02-AG; 1 patient with subtype A). Of the 42 subjects tested, we found 2 (4.8%) mutations in NRTI (V118I), but did not find a mutation in NNRTI as well as in the PI region. CONCLUSIONS: The prevalence of transmitted antiretroviral drug resistance in drug-naive patients is still low in Korean patients.
