PURPOSE: The purpose of this study was to suggest agenda priorities for nursing service R&D (Research and Development) related policies development. METHODS: Two steps in developing the agendas and priorities were performed in this descriptive study. First, nursing service R&D agendas were extracted through needs assessment of nursing researchers and practitioners. Then, the priority of agendas was set by Analytic Hierarchy Process by ten experts who were representatives of nursing and other healthcare professionals. RESULTS: Six core areas and forty-six nursing service R&D agendas were developed. The priority of agendas was different according to the evaluation criteria depending on weight value of nursing services. CONCLUSION: In order to select and promote nursing service R&D projects within national healthcare policy, nursing service R&D policy should be proposed with consideration to the importance of the criteria in reflecting characteristics of nursing care. By strengthening R&D capabilities for quality improvement and sensitive awareness of national directions for healthcare R&D policies, nursing service R&D can be appropriately promoted.

There is a dearth of Korean studies on dehydration, one of the health risks for adult women. This study analyzed the subjects of the 2016∼2018 National Health and Nutrition Examination Survey (KNHANES) to investigate the relationship between nutrient intake ratios and sedentary time in dehydrated women. Body mass index and waist circumference in the dehydrated group (DG) were significantly higher than the normal group (NG). Intake of other liquids in the DG was significantly higher than in the NG, but total water intake in the DG was significantly lower than in the NG. Compared to the 600 sedentary minutes or more per day group, the odds ratio of dehydration was significantly higher in the less than 300 sedentary minutes per day group (1.871 [95% CI: 1.579∼2.215], P＜0.001). Compared to the drinking over 6.0 cups of water per day group, the odds ratio of dehydration was significantly higher in the 3 cups or fewer per day (OR [95% CI] is 1.198 times [1.019 to 1.408], P＜0.05), and 6.0 cups or fewer group (OR [95% CI] is 1.162 times [1.018 to 1.326], P＜0.05). The results of this study showed that the total water intake was relatively lower in the ≥600 sedentary minutes per day group compared to the 300 sedentary minutes per day group, making them more vulnerable to dehydration. The nutrient intake ratios were higher in the dehydration group than in the normal group. In conclusion, emphasis should be placed on the importance of hydration and nutrition education for adult women in the workplace.

A 43-year-old female patient with a congenital right coronary artery to right atrial fistula presented as congestive heart failure and aortic valve infective endocarditis. The diagnosis was made on the basis of echocardiography, especially TEE and confirmed by tight heart catheterization & aortography. She underwent aortic valve replacement due to severe aortic valve regurgitation with vegetations, fistulectomy and coronary aneurysmorrhaphy. The postoperative course was uneventful. She was treated with antibiotics because of infective endocarditis for 6 weeks. At present she remains well and visits out patient clinic regularly for oral anticoagulation without problem.

PURPOSE: The purpose of this study was to examine the current status of home care nursing services provided by community health nurses and to identify barriers to the services. METHODS: A cross-sectional survey was conducted with three types of community health care nurses. Participants were 257 nurses, 46 of whom were hospital based home care nurses, 176 were community based visiting nurses, and 35 were long term care insurance based visiting nurses. A structured questionnaire on 7 domains of home care nursing services with a 4-point Likert scale was used to measure activities and barriers to care. Data were analyzed using SPSS WIN 21.0 program. RESULTS: Hospital based home care nurses showed a high level of service performance activity in the domain of clinical laboratory tests, medications and injections, therapeutic nursing, and education. Community based visiting nurses had a high level of service performance in the reference domain. Long term care insurance based visiting nurses showed a high level of performance in the service domains of fundamental nursing and counseling. CONCLUSION: The results show that although health care service provided by the three types of community health nurse overlapped, the focus of the service is differentiated. Therefore, these results suggest that existing home care services will need to be utilized efficiently in the development of a new nursing care service for patients living in the community after hospital discharge.

BACKGROUND/AIMS: Paracentesis is an acceptable therapeutic modality for the symptomatic relief of dyspnea or abdominal fullness due to tense ascites in patients with cirrhosis. Whereas studies about the effects of paracentesis focused on the changes about hemodynamics, electrolytes and renal function in great detail, the effects of paracentesis on the changes about respiratory system have undergone limited investigations which are defined large-volume paracentesis. METHODS: We performed pulmonary function tests with arterial blood gas analysis just before and 24 hr after paracentesis. The paracentesis of average 2,300ml was carried out in ten liver cirrhosis patients with tense ascites who were free from underlying cardiopulmonary impairment. RESULTS: 1. The results of pulmonary function test just before paracentesis were as followings; FVC( functional vital capacity), FEV1(forced expiratory volume in 1 sec), FEF25 75(forced expiratory effort 25% 75%) and TLC(total lung capacity) were decreased as 78%, 79%, 62.3% and 89% of normal control value respectively, whereas RV(residual volume) was not decreased. DLCO(lung diffusion capacity of carbon monoxide)was decreased as 61.6%. 2. The results of pulmona function test 24 hr after paracentesis were as followings,' The symptomatic relief of dyspnea was achieved in all participated ten patients. Among lung volume parameters, FVC and VC were increased significantly(p=0.003, p=0.004). Whereas TLC was increased without statistical significance(p=0.228), and RV and FRC(functional residual capacity) showed no change. FEV1 was increased significantly(p=0.039), but FEF25 75 and the ratio of FEF1/FVC showed no change. DLCO was not increased. PaOy(partial pressure of oxygen in arterial blood) was impr'oved without statistical significance. CONCLUSIONS: These results suggest that the patients of liver cirrhosis with ascites have restrictive ventilatory impairment with additional obstructive ventilatory impairment. After paracentesis, the restrictive ventilatop impairment is improved by the relief of diaphragmatic motion limitation caused by ascites. Also, paracentesis of(not large volume, like 5000ml, but) relatively small volume, of 2000 3000ml can achieve objective improvement of dyspnea due to tense ascites.

More than half of the world’s populations are considered to be infected by Helicobacter pylori. It causes a chronic inflammation of the stomach, which is implicated in the pathogenesis of gastric ulcer and cancer. Silibinin, a polyphenolic flavonoid derived from milk thistle, has been known for its hepatoprotective effects, and recent studies have revealed its chemopreventive potential. In the present study, we examined the anti-inflammatory effects of silibinin in human gastric cancer MKN-1 cells and in the stomach of C57BL/6 mice infected by H. pylori. Pretreatment with silibinin attenuated the up-regulation of COX-2 and inducible nitric oxide synthase (iNOS) in H. pylori-infected MKN-1 cells and mouse stomach. In addition, the elevated translocation and DNA binding of NFκB and STAT3 induced by H. pylori infection were inhibited by silibinin treatment. Moreover, H. pylori infection in combination with high salt diet resulted in dysplasia and hyperplasia in mouse stomach, and these pathological manifestations were substantially mitigated by silibinin administration. Taken together, these findings suggest that silibinin exerts anti-inflammatory effects against H. pylori infection through suppression of NF-κB and STAT3 and subsequently, expression of COX-2 and iNOS.

This study evaluated the correlation between serum uric acid level and the nutrients adequacy ratio (NAR) using data from the Korea National Health and Nutrition Examination Survey (KNHANES) 2016∼2019. This is a cross-sectional study in which 6,579 Korean male adults were divided into quartiles according to their uric acid levels. All analyses were performed with adjusted age. Uric acid decreased as the age increased from the age group 19∼29 years to 30∼49 years and then to 50∼64 years. Interquartile results of serum uric acid levels showed that increases in the serum uric acid levels were associated with decreases in LDL-cholesterol (P＜0.01), triglycerides (P＜0.001), body weight (P＜0.001), waist circumference (P＜0.001), body mass index (P＜0.001), systolic blood pressure (SBP) (P＜0.001), diastolic blood pressure (DBP) (P＜0.001). However, uric acid levels decreased with an increase in HDL cholesterol (P＜0.001). The analysis of the NARs according to the quartiles of serum uric acid levels in men showed that an increase in serum uric acid levels was associated with a decrease in the NAR levels of dietary fiber (P＜0.001), calcium (P＜0.001), and folic acid (P＜0.001).

BACKGROUND: Significant aortic stenosis of various underlying etiologies presents with similar clinical characteristics and is usually treated with aortic valve replacement. We performed a clinical study to evaluate the clinical characteristics, changes of echocardiographic parameters before and after aortic valve replacement in adult aortic stenosis patients. METHODS: From January 1991 through December 1995, 159 patients underwent aortic valve replacement at Sejong General Hospital. Sixty-two cases(39%) of those patients were pure or predominant aortic stenosis. We observed the clinical characteristics, etiology, operative procedure, perioperative complication and mortality, And we observed the changes of echocardiographic parameters such as mean and peak pressure gradients at aortic valve, ejection fraction, systolic and diastolic left ventricular internal dimensions, left ventricular wall thickness, left ventricular mass index retospectively at preoperative and postoperative periods regularly within 1 month, 1 yr, 3 yrs after operation(mean follow up period : 16 months, 1-36 months). RESULTS: 1) The age of patients ranged from 31 to 71 years(mean 55+/-11), and 60%(37 cases) of them were men. 2) Regarding underlying heart disease, the most common etiology of aortic stenosis was rheumatic valvular heart disease(32 cases, 52%), followed by congenital bicuspid aortic valve(16 cases, 25%) and degenerative change(14 cases,23%). 3) 44 cases(77%) of the patients had dyspnea,12 cases(19%) had chest pain, and 5 cases(8%) had history of syncope at the time of operation. Asymptomatic patient was only 1 case. 4) Seven patients(11%) had associated coronary artery disease, and only 1 case(about 2%) underwent concomitant coronary bypass surgery. 5) Post-operative complications which developed within 1 month were bleedings(8 cases, 13%), arrhythmias(7 cases, 11%) and infections(4 cases, 6%). After 1 month, bleedings related with anticoagulation were most common(7 cases, 11%). Other complications were hemolytic anemia(1 case), and aortic dissection(1 case). There was one surgery related mortality(2%) which happened during operatin due to myocardial ischemia. 6) The size of implanted prosthetic valves ranged from 19 to 25mm(mean 22+/-2mm). Larger valves(23-25mm) showed lower peak(p=0.839) and mean pressure gradients(p=0.019) than smaller valves(19-21mm). 7) We observed that peak and mean pressure gradient, left ventricular internal dimension, and left ventricular mass index had decreased significantly after aortic valve replacement. 8) The average preoperative functional class(2.3) had improved significantly at 1 month after surgery(1.2), and 1 year after surgery(1.0). CONCLUSIONS: In our series, the most common etiology of aortic stenosis was rheumatic valvular disease(52%). The incidence of combined coronary artery disease was 11%, lower than other reports. And only 1 case(2%) underwent concomitant coronary artey bypass graft surgery. The average size of implanted valves was 22mm, and the larger size had lower transaortic peak and mean pressure gradients after operation. The most common perioperative complication was bleeding and mortality rate was about 2%. Echocardiography was useful for evaluation of postoperative changes, such as transaortic peak and mean pressure gradient, left ventricular internal dimension and left ventricular mass index.

OBJECTIVE: Systemic embolism related with left atrial thrombi is a well known complication of percutaneous ballon valveloplasty of the mitral valve stenosis. The presence of left atrial thtombi is believed to be a contraindication to balloon valvuloplasty. The purpose of this study was to determine whether balloon valvuloplasty is possible in mitral stenosis patients with left atrial thrombi after oral anticoagulation therapy. METHODS: We studied 13 consecutive patients(12 : female, 1 : male, mean age : 44+/-11) who had mitral stenosis and left atrial appendage thrombi by serial transesophageal echocardiography before balloon valvuloplasty of the stenotic mitral valve from May 1995 to January 1997. We started oral anticoagulation in those 13 patients with mitral stenosis and left atrial appendage thrombi to keep the INR 2-3. Regular follow up was performed by transesophageal echocardiagraphy to determine whether the left atrial appendage thrombi are resolved. Patients underwent percutaneous balloon valvuloplasty after complete resolution of left atrial appendage thrombi. RESULTS: 9 patients(69.2%) underwent balloon valvuloplasty after complete resolution of left atrial appendage thrombi with oral anticoagulation for average 6 months. Two (15.4%) patients had normal sinus rhythm. Three patients had coronary A-V fistular due to neovascularization to left atrial appendage thrombi. In four patients, oral antiocoagulation failed to resolve the left atrial appendage thrombi and they underwent balloon valvuloplasty under TEE guide with special caution to avoid systemic embolization. There were no complications such as systemic embolization in those 4 patients. CONCLUSION: Left atrial appendage thrombi in mitral stenosis could be resolved in high proportion(69.2%) by oral anticoagulation therapy. Percutaneous mitral balloon valvuloplasty could be a safe and effective treatment modality despite of the presence of left atrial appendage thrombi after adequate oral anticoagulation therapy.
