Purpose: The purpose of this study was to identify the factors influencing nursing work performance among clinical nurses in the hospital. Methods: This descriptive correlational study collected data from 122 clinical nurses who were working in three tertiary referral hospitals in Busan. The data were collected, using self-reported questionnaires, from September 2 to October 14, 2019. The data were analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficient, and multiple regression using SPSS/WIN 25.0 program. Results: Nursing work performance was significantly associated with resilience, innovation oriented culture, relationship oriented culture, and hierarchy oriented culture. The factors significantly influencing nursing work performance of the participants included relationship oriented culture (β=.27, p=.015), hierarchy oriented culture (β=.25, p=.003), resilience (β=.19, p=.035), and total clinical career (β=.18, p=.030), which explained 27.3% of nursing work performance (F=8.59, p<.001). Conclusion The results indicate that there is a need to improve communication skills among multidisciplinary team members and to harmonize hierarchical and relational cultures in order to enhance nursing work performance. In addition, this study suggests developing interventions for enhancing the resilience of clinical nurses.

PURPOSE: The aim of this study was to investigate the impact of the visceral fat area (VFA) of patients with gastric cancer undergoing laparoscopic surgery on operative outcomes such as number of retrieved lymph nodes (LNs) and operative time. METHODS: We retrospectively reviewed the medical records and the CT scans of 597 patients with gastric cancer who underwent laparoscopy assisted distal gastrectomy (LADG) with partial omentectomy and LN dissection (>D1 plus beta). Patients were stratified by gender, VFA, and body mass index (BMI), and the clinicopathologic characteristics and operative outcomes were evaluated. Multiple linear regression analysis was used to assess the effects of VFA and BMI on the number of retrieved LNs and operative time in male and female patients. RESULTS: The mean number of retrieved LNs was significantly decreased for both male and female patients with high VFA. The operative time was significantly longer for both male and female patients with high VFA. The number of retrieved LNs had a statistically significant negative correlation with VFA in both men and women, but not with BMI. The operative time had a statistically significant positive correlation with VFA in men, whereas the operative time had a statistically significant positive correlation with BMI in women. CONCLUSION: The preoperative VFA of male patients with gastric cancer who undergo LADG may affect the number of retrieved LNs and operative time. VFA was more useful than BMI for predicting outcomes of LADG.

Purpose: To evaluate the clinical efficacy of intense pulsed light (IPL) therapy combined with meibomian gland expression (MGX) in treating meibomian gland dysfunction (MGD) caused by glaucoma eye drops. Methods: This study included 20 patients (aged 18-85 years) who were using glaucoma eye drops and exhibited signs of MGD. Participants underwent four sessions of IPL therapy at 3-week intervals, each followed by MGX. Evaluative measures included the Ocular Surface Disease Index (OSDI), best-corrected visual acuity, Schirmer's test, tear break-up time (TBUT), corneal fluorescein staining score (CFS), lid margin abnormalities, meibomian gland expressibility (MGE), meibum quality, lipid layer thickness (LLT), and meiboscore. These assessments were conducted before and after each treatment. Results: After treatment, significant improvements were observed across all measured parameters, including OSDI, Schirmer's test, TBUT, CFS, lid margin abnormalities, MGE, meibum quality, LLT, and meiboscore. Conclusions IPL therapy combined with MGX was effective in improving ocular surface and eyelid abnormalities among patients with MGD induced by glaucoma eye drops. Our findings support the use of IPL and MGX as safe and effective adjunct therapies for these patients.

BACKGROUND: To prepare for possible emergency situations during dental treatment, it is helpful to know how often and what kinds of emergencies may arise. This study set out to evaluate the incidences, causes, treatments, and outcomes of emergency situations in the outpatient clinic of a dental teaching hospital in Korea. METHODS: We retrospectively reviewed the records of patients who had experienced an emergency situation and emergency response team activated in a selected outpatient clinic between November 2004 and November 2013. Specific information about the emergency cases was collected, including the patient characteristics and the frequency, types, treatments, and outcomes of the emergency situations. RESULTS: We identified 35 instances of emergency situations in 2,890,424 patients (incidence = 0.012 per 10,000 outpatients). The number of cases was as follows: 10 (28.6%) in the Department of Periodontics, 10 (28.6%) in the Department of Oral and Maxillofacial Surgery, 6 (17.1%) in the Department of Oral and Maxillofacial Radiology, 4 (11.4%) in the Department of Prosthodontics, 2 (5.7%) in the Department of Conservative Dentistry, 2 (5.7%) in the Department of Pediatric Dentistry, and 1 (2.9%) in the Department of Orthodontics. Three (8.6%) of the emergency situations arose before treatment, 22 (62.9%) during treatment, 7 (20.0%) after treatment, and 2 (5.7%) in a patient's guardian. CONCLUSIONS: In accordance with the growing elderly population and more aggressive dental procedures, the number of emergency situations may increase in the future. We recommend that clinicians keep in mind airway management and the active control of emergency situations.

OBJECTIVE: betaig-h3 is a 68kDa extracellular matrix protein which is overexpressed in synovial tissues of rheumatoid arthritis (RA). Previous results proved that betaig-h3 fragments are relevant to adhesion and migration of synovial fibroblast and angiogenesis through interaction with alphavbeta 3 integrin. We designed a recombinant betaig-h3 protein consisting of a fas-1 domain and RGD motif and evaluated the therapeutic efficacy in RA. METHODS: Inhibitory effect of adhesion and migration of NIH3T3 cell line was evaluated in 96 well microtiter and transwell plates coated with betaig-h3. Clinical arthritis index was evaluated after treating CIA mice with MFK12. Immunohistochemical staining in synovial tissues were performed. Expression of transcripts and proteins of inflammatory mediators were analyzed by semi-quantitative RT-PCR and immunoblotting. RESULTS: Recombinant protein consisted of 4th fas-1 domain truncated for H1 and H2 sequences and RGD peptide (MFK12), had M.W. of 10.4kDa. betaig-h3 mediated adhesion and migration of NIH3T3 cell line were significantly inhibited in a dose-dependent manner. Arthritis severity and incidence were efficiently reduced when CIA mice were treated with MFK12 at 30 mg/kg/day compared with the control. Immunohistochemical staining of joint tissues in MFK12 treated mice exhibited reduced angiogenesis. In treated mice, expression of transcripts regarding inflammatory mediators was markedly suppressed and immunoblotting of ICAM-1 and RANKL from whole extract of hind paws also showed a significant reduction. CONCLUSION: This study shows that MFK12 is effective in treating RA, although further study is warranted to improve the therapeutic efficacy.

PURPOSE: The adverse effects of obesity on short-term surgical outcomes after laparoscopic colorectal surgery have been reported. However, the influence of obesity on long-term oncological outcomes after laparoscopic surgery in Asian patients has not been well understood. The aim of this study was to evaluate the effect of obesity on long-term oncologic outcomes in patients who underwent laparoscopic surgery for colorectal cancer. METHODS: Overall, 424 consecutive patients who underwent laparoscopic resection for colorectal cancer between January 2005 and July 2012 were included in this retrospective study. Patients were classified as non-obese (body mass index [BMI] <25.0 kg/m²) and obese (BMI ≥25.0 kg/m²) according to the categories proposed by the International Obesity Task Force. A survival analysis was performed using clinicopathologic characteristics, including obesity. RESULTS: Of the 424 patients, 325 (76.7%) were classified as non-obese and 99 (23.3%) as obese. The clinicopathologic characteristics of the obese and non-obese groups were similar, except that there were more underlying comorbidities, a lower frequency of smoking, and fewer tumors in rectum in the obese group. Results of the multivariate analysis showed that older age, elevated serum carcinoembryonic antigen, high-grade histology, advanced tumor stage, and perineural invasion were associated with poorer disease-free survival and overall survival. Obesity was not significantly associated with disease-free survival (hazard ratio [HR], 1.196; 95% confidence interval [CI], 0.686~2.086; p=0.528) or overall survival (HR, 1.156; 95% CI, 0.584~2.289; p=0.677). CONCLUSION: Laparoscopic surgery for colorectal cancer seems to be safe and feasible for obese patients in terms of long-term oncologic outcomes.

Hypothenar hammer syndrome (HHS) is a non-atherosclerotic, non-inflammatory vascular disease that causes a digital ischemia as a result of the occlusion of distal ulnar artery adjacent to the hook of hamate. This syndrome is usually observed in men who use the hypothenar eminence of the hand to grip devices such as a hammer. As a consequence of repeated blunt trauma, the ulnar artery beneath hypothenar eminence may lead to pathologic changes, such as intima-medial hyperplasia and reactive inflammatory infiltrates, which lead to the digital ischemia. We experienced a case of HHS with digital ulcerations which occurred after intensive work with nail remover for 10 days. Selective angiography of right forearm showed complete occlusion of the ulnar artery at the level of hook of hamate with deficient superficial palmar arch. After treatment with intravenous prostaglandin E1 and heparin, the ulcerative lesions of fingers improved without surgical intervention, which implicates that medical management of HHS should be considered prior to the surgical treatment.

The RUNX3 gene is regarded as a tumor suppressor gene in many human solid tumors, and its inactivation is believed to be related with solid tumor carcinogenesis. As little information is available about the role of the RUNX3 gene in breast cancer, we investigated the relationship between the RUNX3 gene and breast cancer. We performed reverse transcriptase-polymerases chain reaction (RT-PCR), methylation specific PCR, and bicolor fluorescent in situ hybridization analysis in an effort to reveal related mechanisms. Forty breast tissue samples and 13 cell lines were used in this study. Eighty-five percent of breast cancer tissues showed downregulated RUNX3 gene expression, whereas it was downregulated in only 25% of normal breast tissues by RT-PCR assay. Sixty-seven percent of breast cancer cell lines showed downregulated RUNX3 expression, but the RUNX3 gene was not expressed in two normal breast cell lines. Hypermethylation was observed in 53% of breast cancer tissues and 57% of breast cancer cell lines. Hemizygous deletion was observed in 43% of breast cancer cell lines. Hypermethylation and/or hemizygous deletion was observed in 5 of 7 breast cancer cell lines, and the four of these five examined showed no RUNX3 gene expression. We suggest that various mechanisms, including methylation and hemizygous deletion, could contribute to RUNX3 gene inactivation.
