Effects of stress, depression, and spousal and familial support on maternal identity in pregnant women

Purpose The objective of this study was to identify the factors influencing maternal identity in pregnant women. Methods Using a descriptive research design, a cross-sectional survey was conducted. In total, 127 pregnant women were recruited from a tertiary hospital in Korea from January to April 2019. Measurements included maternal identity, stress, depression, spousal and familial support, and demographic and obstetric characteristics. Data were analyzed by descriptive statistics, the independent t-test, one-way ANOVA, Pearson correlation coefficients, and stepwise multiple regression using SPSS version 25.0. Results The mean score for maternal identity was 131.15 out of 160, and the mean scores for stress, depression, and spousal and familial support were 14.59 (out of 40), 6.82 (out of 30), and 109.04 (out of 132), respectively. Stress (r=–.38, p<.001), depression (r=–.37, p<.001), and spousal and familial support (r=.37, p<.001) were significantly correlated with maternal identity. In multiple regression analysis, stress (β=–0.27, p=.005) and spousal and familial support (β=0.23, p=.014) were found to be significant factors influencing maternal identity in pregnant women (F=14.19, p<.001). Conclusion It is necessary to develop effective strategies to mitigate stress and to encourage spousal and familial support in pregnant women. Such strategies could further enable pregnant women to enhance their maternal identity

Effect of Incivility, Resilience, and Social Support Experienced by Nursing Students on Burnout in Clinical Practice

PURPOSE: The purpose of the study was to determine effect of incivility, resilience, and social support experienced by nursing students on burnout in clinical practice. METHODS: Subjects were 140 nursing students who agreed to participate in this study. Collected data were analyzed using descriptive statistics, t-test, analysis of variance, Pearson&apos;s correlation and stepwise multiple regression with SPSS WIN 23.0 program. RESULTS: Burnout showed significantly positive correlation with incivility but significantly negative correlations with resilience and social support. Factors affecting burnout were satisfaction with major-dissatisfaction, satisfaction with major-average, social support, grade, and relationship with peers. Satisfaction with major (dissatisfaction) had the greatest effect on burnout, explaining 41% of the total variance. CONCLUSION: According to this study, dissatisfaction with major was identified as the most significant factor influencing burnout of nursing students in clinical practice. Therefore, it is important to develop and implement programs that can reduce dissatisfaction with major and increase social support and relationship with peers in order to lower burnout of nursing students. In addition, a systemic management of fourth-grade students with a high level of clinical practice is necessary to reduce the level of clinical practice. The authors declared no conflict of interest

Occupational Respiratory Cancer in Korea

Malignant mesothelioma and lung cancer are representative examples of occupational cancer. Lung cancer is the leading cause of cancer death, and the incidence of malignant mesothelioma is expected to increase sharply in the near future. Although information about lung carcinogen exposure is limited, it is estimated that the number of workers exposed to carcinogens has declined. The first official case of occupational cancer was malignant mesothelioma caused by asbestos exposure in the asbestos textile industry in 1992. Since then, compensation for occupational respiratory cancer has increased. The majority of compensated lung cancer was due to underlying pneumoconiosis. Other main causative agents of occupational lung cancer included asbestos, hexavalent chromium, and crystalline silica. Related jobs included welders, foundry workers, platers, plumbers, and vehicle maintenance workers. Compensated malignant mesotheliomas were associated with asbestos exposure. Epidemiologic studies conducted in Korea have indicated an elevated risk of lung cancer in pneumoconiosis patients, foundry workers, and asbestos textile workers. Occupational respiratory cancer has increased during the last 10 to 20 yr though carcinogen-exposed population has declined in the same period. More efforts to advance the systems for the investigation, prevention and management of occupational respiratory cancer are needed

Clinical Characteristics and Treatment Outcomes of Mycobacterium kansasii Lung Disease in Korea

*These authors contributed equally to this work. ∙The authors have no financial conflicts of interest. Purpose: While Mycobacterium kansasii is a common cause of nontuberculous mycobacterial (NTM) lung disease in many developed countries, M. kansasii is infrequently isolated in Korea. We investigated the clinical and radiological features and treatment outcomes of M. kansasii lung disease in Korea retrospectively. Materials and Methods: We identified 41 patients with M. kansasii lung disease who met the diagnostic criteria for NTM lung disease in two tertiary referral hospitals in Seoul, Korea, between January 1998 and December 2007. Results: Their median age was 63 years [interquartile range (IQR) 51-75 years] and 33 (81%) were men. Twenty-three patients (56%) were smokers and 13 patients (32%) had previous pulmonary tuberculosis. The most common radiographic findings were nodules (n = 22, 54%) and consolidation (n = 22, 54%). Cavitation was present in 13 patients (32%). Thirty-one patients (76%) were treated with isoniazid, rifampin, and ethambutol. The median treatment duration was 16 months (IQR 9-18 months). The negative conversion rate after 12 months of treatment was 95%. Conclusion: Clinicians should be aware of the various radiographic manifestations of M. kansasii lung disease. With appropriate treatment, these patients have a good prognosis

Mucoepidermoid Carcinoma of the Thymus: A Case Report

Mucoepidermoid carcinoma of the thymus is an extremely rare malignant mediastinal neoplasm, and to our knowledge, only 13 cases have been reported. We report a case of mucoepidermoid carcinoma of the thymus that was seen in a 53-yr-old man with right chest pain. Chest CT scan showed a huge, cystic mass having a focal solid portion with direct invasion of the adjacent anterior chest wall and pericardium in the anterior mediastinum. Mucoepidermoid carcinoma of the thymus should be included in the differential diagnosis for masses of the anterior mediastinum associated with extensive cystic changes, although the carcinoma is exceedingly rare

A Case of a Subepidermal Calcified Nodule on the Sole without Trauma

Subepidermal calcified nodule is an uncommon form of calcinosis cutis, which most commonly occurs in children. It usually presents as an asymptomatic, solitary verrucous nodule on the head and neck region, but occasionally as multiple lesions. Serum calcium and phosphorus levels are usually normal. Histopathology shows well-formed homogeneous eosinophilic material and granules in the upper dermis. Material in the dermis stained with von Kossa was positive. We report on an unusual case of a subepidermal calcified nodule occurring on the sole. A 21-month-old male presented with an oval-shaped, whitish, hard nodule measuring 5×5 mm on the left sole, without any previous history of trauma

Left ventricular dysfunction measured by tissue Doppler imaging and strain rate imaging in hypertensive adolescents

Purpose : Left ventricular (LV) hypertrophy and impaired diastolic function may occur early in systemic hypertension. Diastolic dysfunction is associated with increased cardiovascular risk. Tissue Doppler imaging (TDI)-derived tissue velocity and strain rate are new parameters for assessing diastolic dysfunction. The aim of this study is to determine whether TDI and strain rate imaging (SRI) would improve the ability to recognize early impaired diastolic and systolic functions compared with conventional echocardiography in hypertensive adolescents. Methods : We included 38 hypertensive patients with systolic blood pressure above 140 mmHg or diastolic blood pressure above 90 mmHg. Ejection fraction and myocardial performance index (MPI) were estimated by conventional echocardiography. Peak systolic myocardial velocity, early diastolic myocardial velocity (Em), and peak late diastolic myocardial velocity (Am) were obtained by using TDI and SRI. Results : In the hypertensive group, interventricular septal thickness was significantly increased on M-mode echocardiography. Em&#47;Am was significantly decreased at the mitral valve annulus. Among hypertensive subjects, the E strain rate at basal, mid, and apex was significantly decreased. Systolic strain was significantly decreased at the septum in the hypertensive group. Conclusion : Strain rate might be a useful new parameter for the quantification of both regional and global LV functions and could be used in long-term follow up in hypertensive patients. Early identification by SRI of subjects at risk for hypertensive and ventricular dysfunction may help to stratify risk and guide therapy. Further studies, including serial assessment of LV structure and function in a larger number of adolescents with hypertension, is necessary

Effect of intracoronary adenosine on ergonovine-induced vasoconstricted coronary arteries

Background: This study aimed to evaluate the effect of adenosine on epicardial coronary artery diameterduring ergonovine provocation testing.Methods: A total of 158 patients who underwent an ergonovine provocation test with intracoronaryadenosine injection between 2011 and 2014 were selected. Patients were divided into four groups basedon the severity of percent diameter stenosis following intracoronary ergonovine administration: Group 1,induced spasm &lt; 50%; Group 2, 50–89%; Group 3, 90–99%; and Group 4, total occlusion.Results: Spasm positivity was observed in 44 (27.8%) cases in the study population (mean age, 57.4 ±± 10.7 years). Intracoronary adenosine increased the diameter of the ergonovine-induced epicardialartery by 0.51 ± 0.31 mm, 0.73 ± 0.39 mm, 0.44 ± 0.59 mm, and 0.01 ± 0.04 mm in Groups 1, 2, 3,and 4, respectively. Subsequent administration of nitroglycerin further increased vessel diameter by0.49 ± 0.28 mm, 0.93 ± 0.68 mm, 2.11 ± 1.25 mm, and 2.23 ± 0.69 mm in Groups 1, 2, 3, and 4,respectively. The ratios of adenosine-induced diameter to reference diameter were significantly lowerin patients with spasm positive results (0.68 [0.59–0.76] vs. 0.18 [0.00–0.41], p &lt; 0.001 in the studypopulation; 0.60 [0.54–0.67] vs. 0.40 [0.27–0.44], p &lt; 0.001 in Group 2) with the best cut-off value of0.505 (sensitivity 0.955, specificity 0.921).Conclusions: Intracoronary administration of adenosine dilated the ergonovine-induced vasoconstrictedepicardial coronary artery. The ratio of adenosine-induced diameter to reference diameter wassignificantly lower in patients with spasm positive results
