The Effects of Emotional Labor and Grit on Job Satisfaction among Pediatric Nurses / 임상간호연구

Purpose@#This study aimed to identify the relationships among emotional labor, grit, and job satisfaction of pediatric nurses and factors affecting job satisfaction. @*Methods@#A cross-sectional study was conducted on 137 pediatric nurses working in a general hospital in Seoul. Data were collected from January 1, 2022 to January 31. The data were analyzed using SPSS/WIN version 28.0.1.1. @*Results@#The mean score of job satisfaction was 3.63±0.43 (out of 5), emotional labor was 3.70±0.39 (out of 5), and grit was 2.90±0.30 (out of 4). Job satisfaction had positively correlated with emotional labor (r=.27, p=.002) and grit (r=.65, p<.001). The regression analyses showed subcategories of grit had a significant influence on job satisfaction. The factors significantly affecting job satisfaction were persistence to achieve long-term goals (β=.39, p<.001), patient-oriented intrinsic motivation (β=.30, p<.001), and passion to become a nursing professional (β=.21, p=.004). @*Conclusion@#These results suggested a need to increase grit for improving the job satisfaction. Furthermore, it would be necessary to develop a diverse program to increase job satisfaction for pediatric nurses by improving grit.

Trend in Prevalence of Smoking and Motivation to Quit among Korean Adult Male Cancer Survivors over the Last 8 Years: The Korea National Health and Nutrition Examination Survey V–VII (2010–2017) / 가정의학회지

Background@#This study aimed to investigate trends in the prevalence of current smokers and motivation to quit among Korean male cancer survivors. @*Methods@#Out of 20,012 men who participated in the Korea National Health and Nutrition Examination Survey V (2010–2012), VI (2013–2015), and VII (2016–2017), 742 cancer survivors were included. A cancer survivor was defined as a person who concurred to the item, “The cancer has been diagnosed by a doctor” in the health questionnaire. Smoking status was classified as current, former, and never smokers. Regarding motivation to quit smoking, we defined those who had a willingness to quit within 6 months as the willing group. Logistic regression analysis was conducted to examine trends in the prevalence of current smokers and the proportion of the willing group among current smokers. @*Results@#Overall, 3.7% of Korean men who participated in the study were cancer survivors. Current smokers constituted 19.5%, 19.1%, and 15.3% of cancer survivors in phases V, VI, and VII respectively which did not show significant changes (P for trend=0.33). However, the proportion of current smokers in the non-cancer group was significantly reduced to 46.6%, 41.2%, and 38.9% in phases V, VI, and VII, respectively (P for trend <0.001). The proportion of those with a motivation to quit smoking did not show a significant trend in the cancer survivors (P for trend=0.964) and non-cancer group (P for trend=0.884). @*Conclusion@#Prevalence of current smokers and motivation to quit in Korean male cancer survivors did not show significant trends.

Granulomatous peritonitis caused by iatrogenic spillage of ovarian dermoid cystectomy: a case report and literature review

A 39-year-old nulliparous woman experienced continuous mild fever and abdominal pain since undergoing laparoscopic ovarian dermoid cystectomy 3 months previously in a local hospital. Abdominal computed tomography revealed diffuse heterogeneous fat infiltrations with numerous micronodules in the greater and lesser omentum, combined with ascites with thickening of the parietal peritoneum. The patient underwent exploratory laparoscopy, which included partial pelvic peritonectomy, excision of granulomas, and adhesiolysis with massive irrigation. The patient was treated successfully with laparoscopic surgery and all reproductive structures were spared without operative complications. To avoid peritonitis, complete removal of cyst contents and massive irrigation should be performed during ovarian dermoid cystectomy. Conservative surgical treatment may be a good choice for treating granulomatous peritonitis induced by iatrogenic rupture.

Relationship between Dry Eye Syndrome and Frequency of Coffee Consumption in Korean Adults: Korea National Health and Nutrition Examination Survey V, 2010–2012 / 가정의학회지

BACKGROUND: Dry eye syndrome is a common health problem in the adult population. Many risk factors including age, sex, prior eye surgery, various chronic diseases, and lifestyle factors can affect its development. We have evaluated the risk of dry eye syndrome based on the frequency of coffee consumption among Korean adult population. METHODS: A total of 9,752 adults with age 19 years and older were randomly selected between 2010 and 2012. They have all participated in the National Health and Nutrition Examination Survey V of Korea. Dry eye syndrome was being diagnosed by the physicians at some points in the participant’s lifetime. The average daily coffee intake was divided into the following: less than 1 cup, 1 to 2 cups, and 3 cups or more. Various physio-environmental factors and medical conditions were used as correction variables to assess the risk of dry eye syndrome in relation to the frequency of coffee consumption. RESULTS: The prevalence of dry eye syndrome decreased to 9.2%, 8.8%, and 6.3% as coffee consumption increased from less than 1 cup to 1–2 cups and more than 3 cups, respectively. However, there was no significant relationship between the frequency of coffee consumption and the risk of dry eye syndrome after adjusting various risk factors. CONCLUSION: There is no relationship between the frequency of coffee consumption and risk of dry eye syndrome.

Relationship between Age at Menarche and Metabolic Syndrome in Premenopausal Women: Korea National Health and Nutrition Examination Survey 2013–2014 / 가정의학회지

BACKGROUND: Early menarche may be associated with increased risk of cardiovascular disease. The aim of this study was to evaluate the relationship between age at menarche and metabolic syndrome (MetS) in Korean premenopausal women. METHODS: We used nationally representative data from the Korea National Health and Nutrition Examination Survey from 2013 to 2014, and 3,023 premenopausal women aged 20–55 years were our subjects. We defined early menarche as age at first menstrual period less than 12 years. Multivariable logistic regression analysis was used to evaluate the relationship between age at menarche and MetS after adjusting for current age, and socioeconomic, lifestyle, and reproductive variables. RESULTS: MetS was much more common in women aged 40–55 years than in women aged 20–39 years (4.1% vs. 15.1%). Compared with women who experienced menarche at age 12–15 years, the risk of MetS in the early menarche group was not higher in either age group, after adjusting for current age, and socioeconomic, lifestyle, and reproductive variables (odds ratio [OR], 1.767; 95% confidence interval [CI], 0.718–4.351 in those aged 20–39 years; OR, 1.780; 95% CI, 0.775–4.085 in those aged 40–55 years). The risk of MetS in women with menarche at age ≥16 years was not higher than in women with menarche at age 12–15 years. CONCLUSION: Early or late menarche was not associated with an increased risk of MetS in premenopausal Korean women. Even before menopause, current age has a major influence on the development of MetS.

An atypical case of Lemierre syndrome following oropharyngeal infection / 고신대학교의과대학학술지

Lemierre syndrome is characterized by anaerobic bacterial infection in the head and neck and clinical or radiological evidence of internal jugular vein thrombophlebitis. The most common pathogens are Fusobacterium species, particularly Fusobacterium necrophorum. Septic emboli resulting from infected thrombophlebitis of the internal jugular vein leads to metastatic infections involving lung, liver, kidney, bone and central nervous system. The accurate diagnosis and treatment is important because it may be associated with a high mortality rate if untreated. We present a case of 28-year-old man with an atypical history for the diagnosis of Lemierre syndrome, which showed no definite evidence of internal jugular thrombophlebitis.

Relationship between Perceived Health Status andPatient Satisfaction in Outpatient Settings - Korean National Health and Nutrition Examination Survey 2015 / 의료커뮤니케이션

BACKGROUND: It is important to investigate patient satisfaction to improve the quality of healthcare. Among the many factors that affect patient satisfaction, perceived health status has been considered as one of the major factors. Therefore, we investigated patient satisfaction through patient experience in outpatient settings according to perceived health status.METHODS: This cross-sectional study using questionnaires of patient experience and perceived health status from the Korean National Health and Nutrition Examination Survey 2015 included 4267 people aged over 19 years who met the inclusion criteria. Perceived health status was classified into three: good, fair, and poor. Questions about patient experience consisted of four items: doctor spending enough time with patients, doctor providing easy-to-understand explanation, doctor giving opportunity to ask questions or raise concerns, and doctor involving patient in decisions about care or treatment. Patient experience was classified into two: satisfied and non-satisfied. A multivariate regression model was used to analyze the data.RESULTS: In the good perceived health status group, level of satisfaction was 79.2%, 88.5%, 83.3% and 87.2%, respectively for the four items targeting patient experience. In the poor group, level of satisfaction was 76%, 84.9%, 79.5%, and 83.1%, respectively for the four items. In multivariate logistic regression analyses, the odds ratios of good perceived health status group were 1.775 (1.347–2.338), 1.946 (1.356–2.793), 1.652 (1.218–2.240), and 1.665 (1.193–2.323) compared with the poor group.CONCLUSION: Perceived health status is associated with patient satisfaction. In particular, the better the perceived health status, the better the patient satisfaction through patient experience.

Ondansetron Inhibits Voltage-Gated K⁺ Current of Ventricular Myocytes from Pregnant Mouse

BACKGROUND: The Htr3a antagonist, ondansetron, has been reported to prolong the QT interval and induce Torsades de pointes in the treatment of postoperative nausea and vomiting. To explore the mechanisms underlying these findings, we examined the effects of ondansetron on the mouse cardiac voltage-gated K⁺ (Kv) channel. METHODS AND RESULTS: Ondansetron increased QT intervals in late pregnant (LP) mice. We measured the Kv channels in freshly isolated left ventricular (LV) myocytes from non-pregnant (NP) and late pregnant (LP) mice, using patch-clamp electrophysiology. Ondansetron blocked Kv current at a dose of 50 µM, and reduced the amplitude of peak current densities in a dose-dependent manner (0, 1, 5, 50 µM), in LP but not in NP mice. In contrast, serotonin and the Htr3 agonist, m-CPBG, increased Kv current densities in NP, but not in LP mice. Interestingly, during pregnancy, serum serotonin levels were markedly increased, suggesting the saturation of the effect of serotonin. Immunostaning data showed that Kv4.3 protein and Htr3a co-localize at the membrane and t-tubule of cardiomyocytes. Moreover, Kv4.3 membrane trafficking was enhanced in response to Htr3a-mediated serotonin stimulation in NP, but not in LP mice. Membrane analysis showed that serotonin enhances Kv4.3 membrane trafficking in NP, but not LP mice. CONCLUSION: Ondansetron reduced Kv current densities, and reduced the Kv4.3 membrane trafficking in LP mouse ventricular cardiomyocytes. This data suggests that QT prolongation by ondansetron is mediated by the reduction of Kv current densities and Kv4.3 membrane trafficking.

Altered Functional Connectivity of the Default Mode Network in Low-Empathy Subjects

Empathy is the ability to identify with or make a vicariously experience of another person's feelings or thoughts based on memory and/or self-referential mental simulation. The default mode network in particular is related to self-referential empathy. In order to elucidate the possible neural mechanisms underlying empathy, we investigated the functional connectivity of the default mode network in subjects from a general population. Resting state functional magnetic resonance imaging data were acquired from 19 low-empathy subjects and 18 medium-empathy subjects. An independent component analysis was used to identify the default mode network, and differences in functional connectivity strength were compared between the two groups. The low-empathy group showed lower functional connectivity of the medial prefrontal cortex and anterior cingulate cortex (Brodmann areas 9 and 32) within the default mode network, compared to the medium-empathy group. The results of the present study suggest that empathy is related to functional connectivity of the medial prefrontal cortex/anterior cingulate cortex within the default mode network. Functional decreases in connectivity among low-empathy subjects may reflect an impairment of self-referential mental simulation.

Positive Peri-Stent Vascular Remodeling and Late-Acquired Incomplete Stent Apposition in Intravascular Ultrasound (IVUS) after Drug-Eluting Stent Implantation / 계명의대학술지

The peri-stent vascular changes after 2nd generation drug-eluting stent (2G DES) implantation have not been fully investigated compare to 1st generation DES (1G DES). From March 2003 to October 2010, patients receiving percutaneous coronary intervention (PCI) with either 1G or 2G DES were retrospectively included. All patients underwent intravascular ultrasound (IVUS) at post-procedure and 8-12 months after PCI. A total of 281 patients (1G DES: 201 patients with 217 lesions and 2G DES: 80 patients with 88 lesions) were enrolled. The incidence of positive peri-stent vascular remodeling (PPVR) and late-acquired incomplete stent apposition (LAISA) were investigated by IVUS images. Major adverse cardiac events (MACE) up to 3 years were also evaluated. The lesion and the stent length were shorter, and the stent size was larger in the 2G DES group. The incidences of PPVR and LAISA were lower in the 2G DES group before and after propensity score matching. However, the incidence of 3-year MACE were not different between the two groups. Independent predictors for PPVR or LAISA were stent length and 1G DES implantation. These results suggested that biocompatible stent system in 2G DES might have reduced peri-stent vascular changes.

Treatment of a Patient with Kaposi's Sarcoma Arising during Hemodialysis with the Multikinase Inhibitor Pazopanib / 대한내과학회지

Kaposi's sarcoma (KS) is an unusual multifocal neoplastic angioproliferative disorder. We herein report a case of classic KS that occurred in a patient receiving hemodialysis for 7 years. The patient had a history of chronic renal failure due to glomerulonephritis for 20 years. Multiple reddened violaceous patches, plaques, and nodules were found on the right knee. Biopsy revealed positivity for human herpesvirus 8 (KS-associated herpesvirus) consistent with KS. Pazopanib, a multitarget tyrosine kinase inhibitor, is an effective agent for treatment of advanced soft tissue sarcoma. The patient received pazopanib for 6 months investigate its effects on KS. The skin lesions and painful symptoms showed improvement. Further studies are required to determine the mechanism underlying the anticancer action of pazopanib and the pathogenesis of KS.

Factors Associated with Hemorrhoids in Korean Adults: Korean National Health and Nutrition Examination Survey / 가정의학회지

BACKGROUND: Although hemorrhoids are one of the most common anal diseases among Koreans, risk factors for hemorrhoids have not been well identified. METHODS: We analyzed the data from the 4th Korean National Health and Nutrition Examination Survey (KNHANES) between 2007 and 2009. Study subjects were 17,228 participants of KNHANES who were aged 19 years or older. Logistic regression analysis was conducted to evaluate associations between hemorrhoids and probable risk factors. RESULTS: Overall prevalence of hemorrhoids among study subjects was 14.4%, being more prevalent among women (15.7%) than among men (13.0%). Obesity and abdominal obesity were associated with a higher risk of hemorrhoids with odds ratio (OR) (95% confidence intervals, 95% CI) of 1.13 (1.01 to 1.26) and 1.16 (1.04 to 1.30), respectively. Both self-reported depression (OR, 1.83; 95% CI, 1.62 to 2.08) and physician diagnosed depression (OR, 1.71; 95% CI, 1.35 to 2.17) were associated with significantly higher risk of hemorrhoids. No regular walking (OR, 1.11; 95% CI, 1.00 to 1.23) and experience of pregnancy (OR, 1.62; 95% CI, 1.17 to 2.25) for women were also associated with higher risk of hemorrhoids. However, educational level, alcohol consumption, physical activities, diabetes mellitus, hypertension, fiber, fat intake, and energy intake were not associated with a risk of hemorrhoids. Low quality of life assessed with EuroQol-5 Dimension and EuroQol-Visual Analogue Scale was significantly associated with hemorrhoids. CONCLUSION: This nationwide cross-sectional study of Korean adults suggests that obesity, abdominal obesity, depression, and past pregnancy may be risk factors for hemorrhoids and hemorrhoids affect quality of life negatively.

Factors Associated with Persistent Smoking after the Diagnosis of Cardiovascular Disease / 가정의학회지

BACKGROUND: Although cigarette smoking is a major modifiable risk factor for the occurrence of primary and secondary cardiovascular disease (CVD), not all survivors from CVD attacks can successfully stop smoking. However, little is known about the factors associated with the change in smoking behavior after CVD attack. METHODS: Study subjects included 16,807 participants (> or =19 years) in the fourth Korean National Health and Nutrition Examination Surveys. From them, we selected 180 persons who had previous CVD diagnosis (angina pectoris, myocardial infarction, or stroke) and were smoking at the time of CVD diagnosis. Then, we categorized the 180 persons into two groups according to change in smoking status after the CVD: quitter and non-quitter. Logistic regression analysis was done to evaluate multivariable-adjusted association. RESULTS: Even after CVD diagnosis, 63.60% continued to smoke. Fully-adjusted analysis revealed that regular drinking (odds ratio [OR], 4.44) and presence of smokers among family members (OR, 5.86) were significantly (P < 0.05) associated with greater risk of persistent smoking, whereas lower education level (OR, 0.20), larger amount of smoking (OR, 0.95), longer time since diagnosis (OR, 0.88), and diabetes (OR, 0.36) were significantly (P < 0.05) associated with decreased risk of persistent smoking after CVD. CONCLUSION: A great proportion of CVD patients tended to continue smoking in the Korean population. In order to reduce smoking rates among CVD patients further, more aggressive efforts towards smoking cessation should be continuously made with consideration of individual socioeconomic, behavioral, and clinical characteristics of CVD patients.

Rapid Isolation of Adipose Tissue-Derived Stem Cells by the Storage of Lipoaspirates

PURPOSE: This study examined a rapid isolation method decreasing the time and cost of the clinical application of adipose tissue-derived stem cells (ASCs). MATERIALS AND METHODS: Aliquots (10 g) of the lipoaspirates were stored at 4degrees C without supplying oxygen or nutrients. At the indicated time points, the yield of mononuclear cells was evaluated and the stem cell population was counted by colony forming unit-fibroblast assays. Cell surface markers, stem cell-related transcription factors, and differentiation potentials of ASCs were analyzed. RESULTS: When the lipoaspirates were stored at 4degrees C, the total yield of mononuclear cells decreased, but the stem cell population was enriched. These ASCs expressed CD44, CD73, CD90, CD105, and HLA-ABC but not CD14, CD31, CD34, CD45, CD117, CD133, and HLA-DR. The number of ASCs increased 1x1014 fold for 120 days. ASCs differentiated into osteoblasts, adipocytes, muscle cells, or neuronal cells. CONCLUSION: ASCs isolated from lipoaspirates and stored for 24 hours at 4degrees C have similar properties to ASCs isolated from fresh lipoaspirates. Our results suggest that ASCs can be isolated with high frequency by optimal storage at 4degrees C for 24 hours, and those ASCs are highly proliferative and multipotent, similar to ASCs isolated from fresh lipoaspirates. These ASCs can be useful for clinical application because they are time- and cost-efficient, and these cells maintain their stemness for a long time, like ASCs isolated from fresh lipoaspirates.

Difference in Viability of CD34+Cells in Cryopreserved Cord Blood According to Evaluation Methods

BACKGROUND: On performing umbilical cord blood (UCB) transplantation, faster engraftment may lead better clinical outcome. Because transplanted viable cell count in UCB is related to the engraftment, accurate evaluation of viability of CD34+cells in cryopreserved UCB has clinical implication. We examined the difference in viability of cells in cryopreserved UCB according to the duration of cryopreservation and different methods. METHODS: A total of 60 UCB samples which were cryopreserved for 1 to 4 years were used in this study. Viability of cryopreserved cells were examined with trypan blue exclusion assay, DNA contents analysis, caspase-3 activation test, intracellular esterase activity and Annexin-V/PI staining. RESULTS: After thawing the cryopreserved UCB, 89% of the total MNCs and 84% of CD34+cells were viable as identified by trypan blue exclusion assay. In the CD34+cell population, the cell death rate was found to be 47% by Annexin-V/PI staining and less than 5% by DNA contents analysis. However, cspase-3 activity failed to document apoptosis. The intracellular esterase activity test also showed a cell death rate of about 10~20% at 2, 4, and 6 hours after thawing. CONCLUSION: Viable cells in UCB should be measured by several compensatory techniques rather than a single method. Discordance among Annexin-V/PI staining versus trypan blue exclusion, DNA contents analysis, and the caspase-3 activation test or intracellular esterase activity should be clarified in order to apply these techniques for actual cord blood transplantation.

Changes of Serum ADH Level during Matoidectomy under General Anesthesia / 대한마취과학회지

BACKGROUND: Markedly reduced urine have been commonly observed during mastoidectomy under general anesthesia. The aim of study was to evaluate the surgery-related mechanism of reduced urine during mastoidectomy. METHODS: 11 patients undergoing mastoidectomy were studied. Blood samples were drawn from CVP line inserted through right internal jugular vein just before drilling (Pre-D); at 15 min after drilling (D-15); at the time closest to the inner ear (CHP-1); at 15 min (CHP-2) and 30 min (CHP-3) after CHP-1 and just before emergence (End). MAP, HR, temperature, CVP, and urine output (UO) were recorded at each period. 0.9% normal saline with room temperature was used to irrigate surgical field. Serum ADH, and the osmolalities (serum and urine) were measured. In 6 patients, serum TSH and FSH were measured, simultaneously. RESULTS: There were no significant hemodynamic changes during procedure. UO was decreased in 50% during and after the drilling. No differences showed in UO between before and after the drilling of CHP. Plasma ADH level after the CHP was increased 2-3 fold than before. Serum osmolality was unchanged throughout the periods, while the urine osmolality was significantly increased after the period of CHP. FSH was not changed during the periods and TSH was decreased slightly than in Pre-D. CONCLUSIONS: The reduced urine output during mastoidectomy may be influenced by the drilling-related vibration, which may affect the supraoptico-hypophyseal tract, resulting in ADH release. The irrigated isotonic saline with higher osmolality (308 mOsm/kgH2O) than plasma osmolality may partly contributed to the increased ADH.

Changes in Student Nurses' Perception between Initial and Final Clinical Practice / 기본간호학회지

PURPOSE: The purpose of this study was to explore perception of clinical experience between the initial and final practice and to explore changes in the perception of clinical experience. METHODS: The study used a Q-method to measure perception of clinical practice. Thirty-six statements made up the finalized Q-sample. The P sample used thirty three nursing college students from K university. The initial collection was done in the first semester of their junior year and second collection was done in the last semester of their senior year. The Q-sorts by each student were coded and analysed with the Quanl PC program. RESULTS: Many students classified as having the perception type 'alienation of ideal and reality' or 'perception of limitation of ability' in the initial clinical practice changed to the type, 'active participation' by the final clinical practice. Further, in the initial clinical practice, part of 'active participation' and 'perception of limitation of ability' changed to 'alienation of ideal and reality'. CONCLUSION: This study shows that perception of their clinical practice by student nurses changed in a positive direction through clinical experience and that this fact was related to the level of satisfaction with nursing. The knowledge and understanding obtained in this research provide insights for nursing faculty and students involved in nursing education.

Anesthesia for Fetal Surgery: Twin Reversed Arterial Perfusion Sequence / 대한마취과학회지

It is important to consider the fetal, uteroplacental, and maternal issues when choosing anesthetic technique for fetal surgery. The twin reversed arterial perfusion (TRAP) sequence, or the acardiac anomaly, occurs in 1:100 monozygous multiple pregnancies and in 1:35,000 births. The TRAP sequence is characterized by placental vascular arterio-arterial anastomosis between twin fetuses, one an acardiac/acephalic twin that receives its blood flow from the normal pumping twin, thereby endangering the normal twin by high output cardiac failure. The acardiac twin is nonviable, and perinatal mortality in the pump cotwin exceeds 50% because of cardiac failure and prematurity. This can be managed by fetal surgery. We report on a patient with a 26-wk gestation complicated by an acardiac/acephalic fetus anesthetized for surgical umbilical cord ligation.
