Purpose: This study aimed to describe nurses’ perceived needs and barriers to pediatric palliative care (PPC). Methods: Mixed methods with an embedded design were applied. An online survey was conducted for nurses who participated in the End-of-Life Nursing Education Consortium- Pediatric Palliative Care (ELNEC-PPC) train-the-trainer program, of whom 63 responded. Quantitative data were collected with a survey questionnaire developed through the Delphi method. The 47 items for needs and 15 items for barriers to PPC were analyzed with descriptive statistics. Qualitative data were collected through openended questions and analyzed with topic modeling techniques. Results: The mean scores of most subdomains of the PPC needs were 3.5 or higher out of 4, and those of PPC barriers ranged from 3.22 to 3.56, indicating the items in the questionnaire developed in this study properly reflect each factor. The needs for PPC were divided into 4 categories: “children and adolescents,” “families,” “PPC management system,” and “community-based PPC.” Meanwhile, PPC barriers were divided into 3 categories: “healthcare delivery system,” “healthcare provider,” and “client.” The keywords derived from the topic modeling were perception, palliative, children, and education for necessities and lack, perception, medical care, professional care providers, service, and system for barriers to PPC. Conclusion In this study, by using mixed-methods, items of nurses’ perceived needs and barriers to PPC were identified, categorized, and weighted, and their meanings were explored. For the stable establishment of PPC, the priority should be given to improving perceptions of PPC, establishing an appropriate system, and training professional care providers.

Background: Dietary intake of n-3 fatty acids have been suggested for their protective role against cardiovascular disease. However, findings from recent studies have been inconsistent. Thus, we investigated the association between dietary intake of n-3 fatty acids and the 10-year risk of cardiovascular disease (CVD). Methods: We analyzed data from 17,390 adults who were aged 30–64 years and free of CVD using the Korea National Health and Nutrition Examination Survey, 2012–2016. Dietary intake of n-3 fatty acids was calculated by using food-frequency questionnaire, and the 10 year risk of CVD was calculated by Framingham general cardiovascular disease risk score (2008) model. We analyzed the odds ratios (ORs) and 95% confidence intervals (CIs) from logistic regression to evaluate the association between dietary intake of n-3 fatty acids and the 10-year risk of CVD. Results: Logistic regression anlaysis showed that dietary intake of n-3 fatty acids was not significantly associated with the 10-year risk of CVD, after adjusting for confounders (OR=0.91; 95% CI, 0.77–1.07). But higher dietary intake of n-3 fatty acids was associated with reduced the 10-year risk of CVD for the female (OR=0.74; 95% CI, 0.58–0.95). Conclusion Our research indicated no significant association between dietary intake of n-3 fatty acids and the 10-year risk of CVD. But the inverse association was observed in the female.

BACKGROUND: Based on scientific evidence, the Korean National Health Examination recommends age 40 as an appropriate time for screening. However, awareness of the health examination itself or of the appropriate age for screening has not been discussed extensively with examinees. This study aims to evaluate the perception about age at the start and end of periodic health examinations (PHE). METHODS: A self-administered survey was completed by 887 subjects who visited either the health promotion center or the outpatient clinic at a university hospital in Korea between February 15 and May 18, 2016. Participants were divided into two groups: 587 were periodic health examinees, and 300 were visitors to the family medicine clinic. Their awareness of PHE was compared using the Chi-square test and multiple logistic regression. RESULTS: Both groups had similar (P>0.05) perceptions regarding the awareness, knowledge and usefulness of the PHE. Both groups preferred to continue taking a PHE with no upper limit on the age when it could be taken. This tendency was more prominent among subjects with higher levels of education and household income. In both groups with individuals under age 50 said that the appropriate age to begin screening is 40 or younger. CONCLUSIONS: The perception regarding the ages at which to start and end the PHE was confirmed according to the subject of visit; a wider range of appropriate ages was preferred than is included in the current recommendations.

Purpose: For patients with time-critical acute coronary syndrome, reporting electrocardiogram (ECG) findings is the most importantcomponent of the treatment process. We aimed to develop and validate an automated Fast Healthcare InteroperabilityResources (FHIR)-based 12-lead ECG mobile alert system for use in an emergency department (ED). Materials and Methods: An automated FHIR-based 12-lead ECG alert system was developed in the ED of an academic tertiarycare hospital. The system was aimed at generating an alert for patients with suspected acute coronary syndrome based on interpretationby the legacy device. The alert is transmitted to physicians both via a mobile application and the patient’s electronic medicalrecord (EMR). The automated FHIR-based 12-lead ECG alert system processing interval was defined as the time from ED arrivaland 12-lead ECG capture to the time when the FHIR-based notification was transmitted. Results: During the study period, 3812 emergency visits and 1581 12-lead ECGs were recorded. The FHIR system generated 155alerts for 116 patients. The alerted patients were significantly older [mean (standard deviation): 68.1 (12.4) years vs. 59.6 (16.8)years, p<0.001], and the cardiac-related symptom rate was higher (34.5% vs. 19%, p<0.001). Among the 155 alerts, 146 (94%) weretransmitted successfully within 5 minutes. The median interval from 12-lead ECG capture to FHIR notification was 2.7 min [interquartilerange (IQR) 2.2–3.1 min] for the group with cardiac-related symptoms and 3.0 min (IQR 2.5–3.4 min) for the group withnon-cardiac-related symptoms. Conclusion An automated FHIR-based 12-lead ECG mobile alert system was successfully implemented in an ED.

Background: Post-transplant immunosuppression with calcineurin inhibitors (CNIs) is associated with kidney function impairment while mammalian target of rapamycin (mTOR) inhibitors, such as everolimus, can be used for its renal-sparing effects. In this study, we compared the efficacy and safety of everolimus with low dose tacrolimus (EVR+Low TAC) and conventional dose tacrolimus (TAC) in liver transplantation recipients. Methods: Medical records of recipients who received liver transplantation at Seoul National University Bundang Hospital from January 1st 2009 to December 31st 2018 were retrospectively reviewed. Cohort entry date was defined as the day everolimus was initiated and tacrolimus dosage was reduced. All patients were followed up for 1 year. Indicator of efficacy was the incidence of rejection and safety was evaluated by incidence of drug adverse events including renal function. Results: Among 118 patients, there were 40 patients (33.9%) in EVR+Low TAC group. Incidence of rejection, including both biopsy proven acute rejection and clinical rejection, was similar in two groups [7.5% (n=3) vs. 6.4% (n=5), p=1.000]. Renal dysfunction was less frequent in EVR+Low TAC [17.5% (n=7) vs. 35.9% (n=28), p=0.038]. However, incidence rates of dyslipidemia, oral ulcer were more frequent in EVR+Low TAC [45.0% (n=18) vs. 21.8% (n=17), p=0.009; 15.0% (n=6) vs. 1.3% (n=1), p=0.006]. Conclusions In terms of prevention of rejection, EVR+Low TAC was as effective as TAC and had renal-sparing effect but was associated with increased risk of dyslipidemia and oral ulcer. This study demonstrates that EVR+Low TAC could be an alternative to liver transplant recipients with nephrotoxicity after administration of conventional dose tacrolimus.

BACKGROUND/OBJECTIVE: The blue honeysuckle berry (Lonicera caerulea var. edulis L.) is a small deciduous shrub belonging to the Caprifoliaceae family that is native to Russia, China, Japan, and Korea. The berry of this shrub is edible, sweet and juicy and is commonly known as the blue honeyberry (BHB). This study examined the anti-diabetic potential of BHB on high-fat-diet-induced mild diabetic mice. The hypoglycemic, and nephroprotective effects of the 12-week oral administration of blue honeyberry extract were analyzed. MATERIALS/METHODS: The hypoglycemic effects were based on the observed changes in insulin, blood glucose, and glycated hemoglobin (HbA1c). Furthermore, the changes in the weight of the pancreas, including its histopathology and immunohistochemical investigation were also performed. Moreover, the nephroprotective effects were analyzed by observing the changes in kidney weight, its histopathology, blood urea nitrogen (BUN), and serum creatinine levels. RESULTS: The results showed that the high-fat diet (HFD)-induced control mice showed a noticeable increase in blood glucose, insulin, HbA1c, BUN, and creatinine levels. Furthermore, growth was observed in lipid droplet deposition related to the degenerative lesions in the vacuolated renal tubules with the evident enlargement and hyperplasia of the pancreatic islets. In addition, in the endocrine pancreas, there was an increase in the insulin-and glucagon-producing cells, as well as in the insulin/glucagon cell ratios. On the other hand, compared to the HFD-treated mice group, all these diabetic and related complications were ameliorated significantly in a dose-dependent manner after 84 days of the continuous oral administration of BHBe at 400, 200 and 100 mg/kg, and a dramatic resettlement in the hepatic glucose-regulating enzyme activities was observed. CONCLUSIONS: By assessing the key parameters for T2DM, the present study showed that the BHBe could act as a potential herbal agent to cure diabetes (type II) and associated ailments in HFD-induced mice.

BACKGROUND: We aimed to investigate the awareness of human immunodeficiency virus (HIV) infection among high-risk individuals, including men who have sex with men (MSM) and medical personnel (MP) in Korea through a cross-sectional survey, identify possible obstacles hindering their access to pre-exposure prophylaxis (PrEP). METHODS: In 2016, the first questionnaire survey was sent to randomly selected MSM and MP. To compare the changes in attitudes and knowledge of MSM, a second questionnaire survey was conducted in August 2017. RESULTS: More than half of MSM (61.3% in 2016, 88.6% in 2017) were aware of PrEP. However, MP who offered PrEP had less knowledge regarding PrEP (23.4%). The background knowledge and experience with PrEP among MSM and MP in this survey was low (3.4% in 2016 and 5.7% in 2017, 1.9% in MP). The major obstacles that MSM reported were lack of insurance coverage (29% in 2016 and 32% in 2017), concern regarding adverse effects of PrEP (19% and 21%), and risk of exposing HIV-positive status to other people (15% and 18%). Among MP, lack of knowledge regarding the efficacy of PrEP was the most common obstacle (30%), followed by lack of insurance coverage (22%), and concern regarding adverse effects (20%). CONCLUSION: Our study showed that PrEP is required among MSM in Korea; however, most MP were not aware of PrEP. Lack of insurance coverage and knowledge regarding PrEP were major hindrances in the access to PrEP; therefore, further studies on how to make PrEP information more accessible are needed to help prevent HIV infection.

Nafamostat mesilate (NM), a synthetic serine protease inhibitor, has anticoagulant and anti-inflammatory properties. The intracellular mediator and external anti-inflammatory external signal in the vascular wall have been reported to protect endothelial cells, in part due to nitric oxide (NO) production. This study was designed to examine whether NM exhibit endothelium dependent vascular relaxation through Akt/endothelial nitric oxide synthase (eNOS) activation and generation of NO. NM enhanced Akt/eNOS phosphorylation and NO production in a dose- and time-dependent manner in human umbilical vein endothelial cells (HUVECs) and aorta tissues obtained from rats treated with various concentrations of NM. NM concomitantly decreased arginase activity, which could increase the available arginine substrate for NO production. Moreover, we investigated whether NM increased NO bioavailability and decreased aortic relaxation response to an eNOS inhibitor in the aorta. These results suggest that NM increases NO generation via the Akt/eNOS signaling pathway, leading to endothelium-dependent vascular relaxation. Therefore, the vasorelaxing action of NM may contribute to the regulation of cardiovascular function.

An allergy skin test is used to diagnose certain allergies by identifying sensitized allergens. In other words, it is a test for patients who are already sensitized to certain allergens. Because of the prevailing perception that beta-lactam allergy can be dangerous and potentially lethal, the intradermal test has long been routinely performed before use to screen beta-lactam allergy in Korea. The prevalence of penicillin allergy is estimated to be 1% to 2%. However, only 14% of the subjects with perceived penicillin allergy is considered to have true penicillin allergy. Moreover, it is difficult to justify performing a skin test on subjects who are very unlikely to be sensitized to beta-lactam, such as those who never used beta-lactam or never experienced allergy after previous use of beta-lactam.Therefore, allergists recommend beta-lactam skin testing in those who have allergy after the use of beta-lactam. Nevertheless, many hospitals in Korea are conducting routine skin tests on patients regardless of a history of beta-lactam allergy, which are not clinically validated but consume considerable human and material resources. False-positive results can consequently result in inappropriate labeling of beta-lactam allergy, leading to the unnecessary restriction of medication prescriptions and the increase in medical expenses. Herein, the drug allergy working group affiliated with the Korean Academy of Asthma, Allergy, and Clinical Immunology announces an expert opinion on the preuse beta-lactam skin test for subjects without a history of beta-lactam allergy based on the objective evidence from the literature and clinical relevance.
