Purpose: The aim of this research was to identify, appraise and synthesize available evidence exploring new nurses' experiences of turnover. Methods: The qualitative meta-synthesis method suggested by Thomas and Harden was used. Qualitative research articles considered for inclusion in the review were identified through an extensive search of relevant literature in scientific databases. Data were extracted from the aforementioned articles, and qualitative research findings were pooled according to Thomas and Harden's review process. This process involved the categorization of findings according to similarity of meaning and aggregation of these sub-themes to produce a comprehensive set of synthesized themes. Results: A total of 4 research articles met the inclusion criteria and were included in the review. The review process resulted in 30 sub-themes that were aggregated into 10 themes: ineffective education; overwhelming work; personal maltreatment by doctors, career nurses, patients and caregivers; lack of professional vision; suffering; fear; loss of confidence; isolation; cynical reaction to turnover; new beginning and growth. Conclusion These findings illuminated the necessity of educational, organizational, emotional and social support for new nurses to help them accomplish their developmental tasks during their transition, as well as the need for this support to continue even after the turnover.

Purpose: The purpose of this study was to investigate the effects of hospital characteristics on employment rate, working period, and retirement of ward nurses in Korea through a retrospective cohort study based on HIRAS data. Methods: Data were obtained from a report on medical care institutions of Health Insurance Review & Assessment Service (HIRAS). Data from 259,941 nurses who were working for a day or more from January 1, 2012, to December 31, 2016, at 2,942 medical care institutions were analyzed. Life table method analysis, Kaplan-Meier analysis, and Cox proportional hazard regression analysis were conducted. Results: The employment rates of 5 yeas and 10 years for the total sample were 38% and 28%, respectively. The estimated mean value of the working period was 3,642.7 days (SE: 17.4 days). Cox proportional hazard regression analyses revealed that nurses who were working at the general hospital/hospital, clinic, and nursing hospital were more likely to leave the hospital compared to those who were working at the 3rd general hospital.Nurses who were working at the medical institutions which were located in cities and countries, established by the private foundation, rated lower levels of nursing, and owned an insufficient number of beds, nurses and doctors were more likely to leave their workplace compared to those of the counterparts. Conclusion This study indicates that hospital characteristics may play a significant role in retirement and working period of ward nurses in Korea. The improvement of hospital conditions to reduce ward nurses’ retirement are needed.

We investigated whether β-carotene (β-CA) or ellagic acid (EA), originating from various fruits and vegetables, has a preventive effect against male infertility induced by exogenous scrotal hyperthermia. ICR adult mice were intraperitoneally treated with 10 mg/kg of β-CA or EA daily for 13 days consecutively. During this time, mice were subjected to transient scrotal heat stress in a water bath at 43℃ for 20 min on day 7, and their testes and blood were obtained on day 14 for histopathologic and biochemical analyses. Heat stress induced significant testicular weight reduction, germ cell loss and degeneration, as well as abnormal localization of phospholipid hydroperoxide glutathione peroxidase (PHGPx) and manganese superoxide dismutase (MnSOD) in spermatogenic and Leydig cells. Heat stress also altered the levels of oxidative stress (lipid peroxidation, SOD activity, and PHGPx, MnSOD, and HIF-1α mRNAs), apoptosis (Bax, Bcl-xL, caspase 3, NF-κB, and TGF-β1 mRNAs), and androgen biosynthesis (serological testosterone concentration and 3β-hydroxysteroid dehydrogenase mRNA) in testes. These changes were all improved significantly by β-CA treatment, but only slightly improved by EA treatment. These findings indicate that β-CA, through modulations of oxidative stress, apoptosis, and androgen biosynthesis, is a potent preventive agent against testicular injuries induced by scrotal hyperthermia.

OBJECTIVES: This study was conducted to identify the demand and willingness to pay for oral hygiene services among elderly people with long-term care insurance. METHODS: Our study was a cross-sectional analysis. Subjects comprised 126 elderly individuals from long-term home-care centers. A total of 28 centers were selected through convenience sampling from among 78 centers in ○○. For analysis, semi-structured questionnaires that required about 20–30 minutes to complete were used. Analysis was performed using SPSS 23.0 software. RESULTS: The overall demand for oral hygiene services was 44.4%, and willingness to pay was 31.0%. Thirty-three people (58.9%) of elderly those who have demand for an oral hygiene service were willing to pay for the service, and 64 people (91.4%) who did not have a demand were not willing to pay for it. Among those with partial dependence on brushing, 65.6% had demand for oral hygiene services and 50.0% were willing to pay costs. Among basic livelihood beneficiaries, 69.6% were willing to pay for oral hygiene services; general subjects and relievers were less willing to pay. CONCLUSIONS: The overall demand for oral hygiene services among elderly people was 44.4%, and the willingness to pay was as low as 31.0%.

Temporal and subcellular distributions of hyaluronic acid (HA) as a degradable nanoparticle (NP) in animals were investigated to determine if HA-NP could be utilized as an appropriate drug delivery system. After mice were intravenously injected with 5 mg/kg of Cy5.5-labeled HA-NP sized 350–400 nm or larger HA-polymers, the fluorescence intensity was measured in all homogenized organs from 0.5 h to 28 days. HA-NP was greatly detected in spleen, liver and kidney until day 28, while it was maintained at low levels in other organs. HA-polymer was observed at low levels in all organs. HA-NP quantities in spleen and liver were reduced until day 3, but increased sharply between days 3 and 7, then decreased again, while their HA-polymers were maintained at low levels until day 28. In kidneys, both HA-NP and HA-polymer showed high levels after 0.5 h of administration, but steadily decreased until day 28. According to ultrastructural analyses, HA-NP was engulfed in Kupffer cells of liver and macrophages of spleen and kidney at day 1 and was accumulated in the cytoplasm of kidney tubular cells at day 7. Overall, these findings suggest that HA-NP could be considered a desirable drug carrier in the liver, kidney, or spleen.

BACKGROUND: To investigate the national molecular epidemiology and resistance profiles of vancomycin-intermediate Staphylococcus aureus (VISA), we analyzed the characteristics of methicillin-resistant Staphylococcus aureus (MRSA) collected from clinical samples at tertiary or general hospitals participating in a nationwide surveillance program for VISA and vancomycin-resistant Staphylococcus aureus (VRSA) in Korea during an 12-week period in each year from 2007 to 2013. METHODS: VISA was defined by agar dilution, broth dilution and E-test methods with vancomycin minimum inhibitory concentrations of >2 μg/mL. All VISA isolates were characterized by multilocus sequence typing, staphylococcal cassette chromosome mec typing, spa typing, accessory gene regulator typing, Diversilab analysis, and antibiogram analysis. RESULTS: Of 109,345 MRSA isolates, 87,354 were screened and 426 isolates were identified as positive on brain heart infusion agar containing 4 μg/mL vancomycin (BHI-V4). Of 426 isolates, 76 isolates were identified as VISA. No VRSA isolates were detected among the isolates. Overall, a total of 6 genotypes were identified among VISA strains and the predominant clones were ST5-II-t2460, ST72-IV-t324, and ST239-III-t037 (44.7%, 15.8%, and 10.5%, respectively). Of note, ST72-IV-t324 clones are known to be a typical community-associated MRSA. ST239-III-t037 strains were more resistant to trimethoprim-sulfamethoxazole than any other type of strain. ST72-IV-t324 strains were susceptible to all of the antimicrobial agents tested except erythromycin and daptomycin. All of the VISA isolates were susceptible to linezolid and quinupristin-dalfopristin. CONCLUSION: Although VRSA is still rare, continuous monitoring of VRSA occurrence is needed, as well as VISA prevalence, epidemic clonal shift, and antimicrobial resistance.

BACKGROUND/AIMS: The meaning of specialized intestinal metaplasia (SIM) in the diagnosis of Barrett's esophagus (BE) is not clear. This study was designed to determine the clinical significance of SIM in the diagnosis of Barrett's esophagus. MATERIALS AND METHODS: Biopsies were taken from 601 subjects with endoscopically suspected columnar-lined esophagus. Under light microscopy with Alcian-blue stain, SIM was identified. Demographic characteristics, gastroesophageal (GE) reflux symptoms and endoscopic findings were compared between the SIM-present group and the SIM-absent group. RESULTS: Among 601 subjects, 184 (30.6%) were confirmed by pathology to have SIM. Age over 40 years (P<0.001) and a medication history of proton pump inhibitor or H2 blocker were found more frequently in the SIM-present group (P=0.01) than in the SIM-absent group. Any of 7 GE reflux symptoms (heartburn, acid regurgitation, chest pain, hoarseness, globus sensation, cough and epigastric soreness) were more frequent in the SIM-present group than SIM-absent group (P<0.001). Specifically, heartburn, chest pain and cough were significantly more common in the SIM-present group. There was no clinically significant difference associated with endoscopic findings or other clinical characteristics. CONCLUSIONS: When subjects with endoscopically suspected BE are analyzed based on the presence or absence of SIM, the SIM-present group was significantly associated with GE reflux symptoms suggestive of frequent GE reflux. However, the presence of SIM did not correlate with endoscopic findings.

PURPOSE: The purpose of this study was to review studies that have examined the quality of life of women with urinary incontinence. MATERIALS AND METHODS: A review was conducted that used the databases PubMED, Proquest, CINAHL, and Sciencedirect. Articles were included that were published in English between 2005 and 2010 the key words use were urinary incontinence, women, and quality of life. RESULTS: A total of 18 studies were identified, and the prevalence of urinary incontinence varied depending on the definition of incontinence used and the age of the population studied. The Incontinence Quality of Life (I-QoL), Incontinence Impact Questionnaire-short form (IIQ-7), and King's Health Questionnaire (KHQ) were the most commonly used instruments. Demographic, medical, physical, psychological, health, and intervention factors were reported as influencing factors on the quality of life of women with incontinence. Age, severity of urinary incontinence, type of urinary incontinence, number of urinary incontinence episodes, body weight, stress, and help-seeking behavior were statistically significant variables influencing quality of life. CONCLUSION: Future studies are needed to identify factors related to quality of life among women with incontinence and to use validated instruments according to specific subjects.

PURPOSE: This study was done to develop an integrated breast health program for prevention and early detection of breast cancer, integrating primary and secondary prevention factors using cognitive-behavioral strategies. METHODS: This methodological study conducted as follows; Selection of components for the program through a literature review, survey to identify women's knowledge and risk perception of breast cancer and diet, and building prototype for the program using discussion based on findings. Using structured questionnaires, interviews were done with 130 women aged 40-59 who lived in a rural area. RESULTS: Primary prevention (diet pattern, knowledge about breast cancer, and risk perception) and secondary prevention (early detection behaviors) factors were identified through the literature review. The survey showed that women lack knowledge and awareness about the risks of breast cancer, and have a low compliance rate for early detection behavior. Based on these results, a program was developed utilizing counseling and models to provide education and practice related to diet, breast cancer, and early detection behaviors. CONCLUSION: Use of this integrated and tailored breast health program with women at risk will contribute to better breast health, but further study is needed to verify the effects.
