OBJECTIVES:
Healthy sleep is important and can have a positive effect on resilience. The aim of the present study was to compare the differences in resilience between two group nurses in rotating shift and daytime fixed work schedules and to investigate stress perception, coping factors, social and psychological health, and sleep factors that may affect resilience.
METHODS:
A total of 400 female nurses having rotating shift and daytime fixed work schedules at two hospitals was surveyed from June 12, 2017 to June 12, 2018. All participants completed perceived stress scale (PSS), stress coping short form (Brief COPE), psycho-social wellbeing Index short form (PWI-SF) or general health questionnaire-18 (GHQ-18), center for epidemiologic studies depression scale (CES-D), STAI-X-1 in state-trait anxiety inventory (STAI), Pittsburgh sleep quality index (PSQI), Epworth sleepiness scale (ESS), insomnia severity index (ISI), Conner Davidson resilience scale (CD-RISC). Independent t-test, paired t-test, Pearson correlation analysis, and multiple regression analysis were applied to the results of the final 373 questionnaires of 400 nurses in two general hospitals.
RESULTS:
Comparing the variable statistics between the two groups of rotating shift and daytime fixed work nurses, showed statistically significant differences in all variables except perceived stress, sleep quality, and daytime sleepiness. Factors that had a significant correlation with resilience were stress coping strategies, depression, and insomnia severity (p < 0.001). In multiple regression analysis, larger positive reframing1 (β = 0.206, p < 0.001), severe less depression (β = −3.45, p < 0.001), and higher psychosocial health (β = 0.193, p < 0.001). As acceptance coping2 increased (β = 0.129, p < 0.05), as daytime sleepiness decreased (β = −1.17, p < 0.05), and as active coping2 increased (β = 0.118, p < 0.05), as the positive reframing2 increases (β = 0.110, p < 0.05), the resilience increased.
CONCLUSION
This study, it was found that resilience was higher in daytime fixed workers than in shift workers. In addition, specific stress coping strategies, psycho-social health, sleep, and depression factors were associated with resilience.

The hemorrhage in hemorrhagic fever with renal syndrome (HFRS) varies from transient petechial lesions to fulminant and massive bleeding. Also in vital organ such as lung, kidney, spleen, brain and pituitary, hemorrhage occasionally occurs spontaneously or by minor trauma. We report a case of retroperitoneal hematoma by spontaneous rupture of renal capsule in HFRS presented with anuria and right flank pain. A 34-year-old male was admitted to our hospital presenting anuria and right flank pain for 3 days. He also had suffered from fever and myalgia since 5 days ago. Sonography and computed tomography were performed at the day of hospitalization and showed massive perirenal hematoma with ruptured renal capsule and spurtting subcapsular renal artery on the right kidney. He was diagnosed as HFRS and treated with hemodialysis, fluid infusion and transfusion. After conservative treatment, he recovered from HFRS without further blood loss.

Purpose:
The purpose of this study was to evaluate the anti-inflammatory effects of non-thermal atmospheric pressure plasma (NTP) on human gingival fibroblasts (HGFs) for clinical application of periodontal treatment.
Materials and Methods:
HGFs were treated with Porphyromonas gingivalis (Pg) lipopolysaccharide (LPS). Customized NTP device was developed for periodontal in vitro study. Cell viability was evaluated with cell counting kit-8. The levels of inflammatory cytokines, including interleukin (IL)-8 and 6, were determined by enzyme-linked immunosorbent assay.
Results:
When NTP was applied, the cell viability did not change significantly, and there was no difference for 6 h and 24h. When Pg LPS was treated to HGFs, the secretion of IL-8 and IL-6 was increased compared to the control group. But when the NTP was applied, the secretion of them was significantly decreased.
Conclusion
NTP did not affect cell viability of HGFs. And it inhibited the LPS-induced production of IL-8 and IL-6.

BACKGROUND/AIMS: Transradial intervention (TRI) is becoming the preferred method over transfemoral intervention (TFI) because TRI is associated with lower incidence of major bleeding and vascular complications. However, there has been limited published data regarding the clinical outcomes of TRI versus TFI in Korean patients with ST-elevation myocardial infarction (STEMI). METHODS: A total of 689 consecutive STEMI patients who underwent primary percutaneous coronary intervention (PCI) with drug-eluting stents (DESs) from January to December of 2009 at nine university hospitals were enrolled in this study. Mid-term angiographic and 12-month cumulative clinical outcomes of the TRI group (n = 220, 31.9%) were compared to those of the TFI group (n = 469, 28.1%). RESULTS: After propensity score matching, in-hospital complications and the 12-month major clinical outcomes during follow-up in the two groups were similar to each other. However, the incidence rates of repeat revascularization (6.4% vs. 0.5%, p = 0.003), target vessel revascularization (6.4% vs. 0.5%, p = 0.003), and major adverse cardiac events (MACE; 11.6% vs. 4.6%, p = 0.018) in the TFI group were higher than those in the TRI group during the 12-month of follow-up. CONCLUSIONS: In our study, TRI in STEMI patients undergoing primary PCI with DESs was associated with lower incidence of access site hematoma, 12-month repeat revascularization, and MACE compared to TFI. Therefore, TRI might play an important role in reducing bleeding complications while improving major clinical outcomes in STEMI patients undergoing primary PCI with DESs.

PURPOSE: This study was undertaken to elucidate the usefulness of urinary betaig-h3 concentrations in differential diagnosis of isolated microscopic hematuria patients. METHODS: Seventy-seven patients, in whom renal biopsy was performed due to microscopic hematuria without proteinuria, were enrolled. The patients were divided into two groups, IgAN group (patients with IgA nephropathy, N=37) and NM group (patients with normal or minor change on renal biopsy, N=40), and the clinical characteristics and laboratory findings were compared between the two groups. TGF-beta and betaig-h3 concentrations in urine were determined by ELISA and were compared between the two groups. To establish the optimal cut-off value of betaig-h3/creatinine (Cr) ratio for the diagnosis of IgA nephropathy, a receiver operating characteristic curve was constructed and the sensitivity and specificity were calculated. RESULTS: A comparative analysis revealed no significant differences in age and sex ratio between the two groups. There were no differences in serum IgG, IgA, IgM, C3, and C4 levels between the two groups. The urinary betaig-h3/Cr ratio was significantly higher in the IgAN group compared to the NM group (6.632.6 vs. 4.462.6 ng/mg, p<0.05), whereas there was no significant difference in the urinary TGF-/Cr ratio between the two groups (14.82.1 vs. 13.75.1 pg/mg, p>0.05). A cut-off betaig-h3/Cr ratio 4.5 has a sensitivity of 85.0% and a specificity of 77.8%. CONCLUSION: The urinary betaig-h3/Cr ratio was a good predictor for the diagnosis of IgA nephropathy. Therefore, renal biopsy should be considered in isolated microscopic hematuria patients with high urinary betaig-h3/Cr ratio.

OBJECTIVE: This study aimed to compare the demographic characteristics and trauma service structures and processes of hospitals in 15 countries across the Asia Pacific, and to provide baseline data for the integrated trauma database: the Pan-Asian Trauma Outcomes Study (PATOS).METHODS: Medical directors and emergency physicians at PATOS-participating hospitals in countries across the Asia Pacific were surveyed through a standardized questionnaire. General information, trauma care system data, and trauma emergency department (ED) outcomes at each hospital were collected by email and analyzed using descriptive statistics.RESULTS: Survey data from 35 hospitals across 15 countries were collected from archived data between June 2014 and July 2015. Designated trauma centers were identified as the highest hospital level for trauma patients in 70% of surveyed countries. Half of the hospitals surveyed had special teams for trauma care, and almost all prepared activation protocol documents for these teams. Most hospitals offered specialized trauma education programs, and 72.7% of hospitals had a hospital-based trauma registry. The total number of trauma patients visiting the ED across 25 of the hospitals was 300,376. The overall survival-to-discharge rate was 97.2%; however, it varied greatly between 85.1% and 99.7%. The difference between survival-to-discharge rates of moderate and severe injury groups was highest in Taiwan (41.8%) and lowest in Thailand (18.6%).CONCLUSION: Trauma care systems and ED outcomes vary widely among surveyed hospitals and countries. This information is useful to build further detailed, systematic platforms for trauma surveillance and evidence-based trauma care policies.

Background:
Preconditioning with inflammatory stimuli is used to improve the secretion of anti-inflammatory agents in stem cells from variant species such as mouse, human, and dog. However, there are only few studies on feline stem cells.
Objectives:
This study aimed to evaluate the immune regulatory capacity of feline adipose tissue-derived (fAT) mesenchymal stem cells (MSCs) pretreated with interferon-gamma (IFN-γ).
Methods:
To assess the interaction of lymphocytes and macrophages with IFN-γ-pretreated fAT-MSCs, mouse splenocytes and RAW 264.7 cells were cultured with the conditioned media from IFN-γ-pretreated MSCs.
Results:
Pretreatment with IFN-γ increased the gene expression levels of cyclooxygenase-2, indoleamine 2,3-dioxygenase, hepatocyte growth factor, and transforming growth factorbeta 1 in the MSCs. The conditioned media from IFN-γ-pretreated MSCs increased the expression levels of M2 macrophage markers and regulatory T-cell markers compared to those in the conditioned media from naive MSCs. Further, prostaglandin E 2 (PGE 2 ) inhibitor NS-398 attenuated the immunoregulatory potential of MSCs, suggesting that the increased PGE 2 levels induced by IFN-γ stimulation is a crucial factor in the immune regulatory capacity of MSCs pretreated with IFN-γ.
Conclusions
IFN-γ pretreatment improves the immune regulatory profile of fAT-MSCs mainly via the secretion of PGE 2 , which induces macrophage polarization and increases regulatory T-cell numbers.

PURPOSE: High sensitive C-reactive protein (hs CRP) is well known as a strong risk factor of cardiovascular disease (CVD). The aim of this study is to evaluate the impact of elevated hs CRP on coronary artery spasm (CAS) as assessed by intracoronary acetylcholine (ACh) provocation test. MATERIALS AND METHODS: A total of 1729 consecutive patients without significant CVD who underwent coronary angiography and intracoronary ACh test between November 2004 and August 2010 were analyzed. The patients were divided into five groups according to quintiles of hs CRP levels. RESULTS: At baseline, the prevalence of elderly, hypertension, diabetes mellitus, current smoking, and lipid levels were higher in patients with higher hs CRP. During ACh test, the incidences of significant CAS, ischemic electrocardiography (EKG) change, multivessel, and diffuse CAS were higher in patients with higher hs CRP. Multivariate analysis showed that the old age (OR=1.01, CI; 1.0-1.02, p=0.0226), myocardial bridge (OR=3.34, CI; 2.16-5.17, p<0.001), and highest quintile hs CRP (OR=1.54, CI; 1.12-2.18, p=0.008) were independent predictors of ACh induced CAS. However, there was no difference in clinical outcomes up to 12 months. CONCLUSION: In conclusion, higher hs CRP was associated with higher incidence of CAS, worse angiographic characteristics and ischemic EKG change, but was not associated with clinical outcomes.

BACKGROUND AND OBJECTIVES: Although the use of heterogeneous overlapping drug-eluting stents (DES) is not uncommon in clinical practice, whether the implantation sequences of heterogeneous DES will influence the endothelialization or arterial responses differently remains unclear. MATERIALS AND METHODS: Twenty-one rabbits were randomized to receive overlapping stents in the iliac artery for 3 months {distal sirolimus-eluting stent (SES, Cypher(TM))+proximal paclitaxel-eluting stent (PES, Taxus(TM)) (C+T, n=7), distal Taxus+proximal Cypher (T+C, n=7) and bare metal stent (BMS)+BMS (B+B, n=7)}. Endothelial function was evaluated by the acetylcholine provocation test during follow-up angiography. Histopathological changes in proximal, overlapped, and distal stented segments were evaluated. RESULTS: Although the overall angiographic outcomes were comparable, late loss (mm) in the distal stented segment was higher in the B+B (0.39+/-0.07) and C+T (0.40+/-0.20) than that in the T+C (0.06+/-0.02) group (p<0.001). The incidence of acetylcholine-induced spasm was higher in the DES groups compared with BMS, regardless of the implantation sequences (85.7% in C+T vs. 14.3% in B+B vs. 71.4% in T+C, p=0.017). Notably, only the distal Cypher implantation group (C+T) had three cases of stent fracture. A histopathological analysis showed that despite similar arterial injury scores, Taxus and Cypher stents had higher inflammatory reactions at the overlapped and distal segments compared with those of BMS. CONCLUSION: Despite similar arterial injury, higher inflammatory reactions were observed in overlapping DES segments regardless of the implantation sequence compared with that of BMS. Moreover, DES was associated with impaired endothelial function on the adjacent non-stented segments.
