Résumé
Purpose@#The first year of the COVID-19 pandemic in Korea elicited changes in healthcare service utilization. This study aimed to report changes in healthcare service utilization among cancer patients during the first year of the COVID-19 pandemic in Korea. @*Materials and Methods@#We analyzed records from National Health Insurance Service Database and identified cancer patients as those with specific beneficiary codes (“V193” or “V194”) assigned to cancer patients. We calculated percentage changes in the number of patients between 2019 and 2020 based on claims records for outpatient clinic visits, hospitalization, and emergency room visits by month, age group, residential areas, and hospital location. @*Results@#The number of newly diagnosed cancer patients in 2020 decreased by 3.2%, compared to the previous year. The number of patients who visited an outpatient clinic, were hospitalized, and visited the emergency room decreased by 2.6%, 4.0%, and 3.5%, respectively, in 2020, compared to the year 2019. @*Conclusion@#During the first year of the COVID-19 pandemic, the number of newly diagnosed cancer patients decreased by 3.2%, compared to the previous year, and their utilization of healthcare services declined significantly after the outbreak of COVID-19.
Résumé
Background/Aims@#Cholangiocarcinoma frequently recurs even after curative resection. Expression levels of proteins such as epidermal growth factor receptor (EGFR), Snail, epithelial cadherin (E-cadherin), and interleukin-6 (IL-6) examined by immunohistochemistry have been studied as potential prognostic factors for cholangiocarcinoma. The aim of this study was to investigate significant factors affecting the prognosis of resectable cholangiocarcinoma. @*Methods@#Ninety-one patients who underwent surgical resection at Samsung Medical Center for cholangiocarcinoma from 1995 to 2013 were included in this study. Expression levels of Ecadherin, Snail, IL-6, membranous EGFR, and cytoplasmic EGFR were analyzed by immunohistochemistry using tissue microarray blocks made from surgical specimens. @*Results@#Patients with high levels of membranous EGFR in tissue microarrays had significantly shorter overall survival (OS) and disease-free survival (DFS): high membranous EGFR (score 0–2) 38.0 months versus low membranous EGFR (score 3) 14.4 months (p=0.008) and high membranous EGFR (score 0–2) 23.2 months versus low membranous EGFR (score 3) 6.1 months (p=0.004), respectively. On the other hand, E-cadherin, Snail, cytoplasmic EGFR, and IL-6 did not show significant association with OS or DFS. Patients with distant metastasis had significantly higher IL-6 levels than those with locoregional recurrence (p=0.01). @*Conclusions@#This study showed that overexpression of membranous EGFR was significantly associated with shorter OS and DFS in surgically resected bile duct cancer patients. In addition, higher IL-6 expression was a predictive marker for recurrence in cholangiocarcinoma patients with distant organ metastasis after surgical resection.
Résumé
Data from the Korean National Health Insurance Service (NHIS) have been widely used to provide real-world evidence. Due to the nature of claims data, researchers use operational definitions to define patients with specific diseases. This study aimed to conduct a systematic review of the operational definitions of liver cancer used in studies based on the NHIS database and to suggest the most appropriate operational definition. Literature search was completed on January 6, 2021, using PubMed and KoreaMed.We applied the most frequently used operational definitions of liver cancer to the NHIS–National Sample Cohort and calculated age-standardized incidence rates (ASRs) of liver cancer by year. The ASRs using each operational definition were compared with the ASR from the Korea Central Cancer (KCCR) data. Among 236 articles, 90 were selected for review, covering histologically various kinds of liver cancer and varied by study subjects. Most studies (n = 79) did not mention whether the codes for the operational definition were from only the main diagnosis or from both the main and sub-diagnosis. The most frequently used operational definition was C22 (n = 39); however, the most similar operational definition was the ASR using “C22.0 or C22.9” for men and “C22.0” for women as the main diagnosis to the ASR from the KCCR. Based on the comparison with KCCR data, we suggest using “C22.0 or C22.9” for men and “C22.0” for women as the main diagnosis for the operational definition of liver cancer when using the NHIS data.

Purpose@#This study investigated the incidence of urinary tract infection (UTI) in community-dwelling adults and identified the association between obesity and UTI. @*Methods@#The participants were 4,926 adults aged over 40 years who had no UTIs at the baseline survey of the Korean Genome Epidemiology Study. Obesity was defined according to the cirtieria of Korean Society for the Study of Obesity using body mass index (BMI) data. UTI was defined as those who had self-reported UTI or had either nitrite, or both leukocytes and blood in the urine dipstick test. Hazard ratio (HR) and 95% confidence interval (CI) were calculated using a multivariate Cox proportional hazards regression analysis to identify the association between the obesity and UTI. @*Results@#The incidence proportion of UTI was 5.1%, and the incidence density per 1,000 person-years was 25.5. After controlling general characteristics, people with BMI ≥30.0 kg/m2 remained 1.66 times (HR = 1.66, 95% CI = 1.06~2.60; p < .05) more likely to have UTI than those with normal weight. This trend was also present in men or people aged ≥ 60 years. Among women aged ≥ 60 years, people with BMI ≥ 30.0 kg/m2 were 1.98 times (HR = 1.98, 95% CI = 1.01~3.86; p < .05) more likely to have UTI than those with normal weight. @*Conclusion@#The BMI ≥ 30.0 kg/m2 is a risk factor of UTIs in Korean adult men over 40 years and women aged ≥ 60 years. It is necessary to emphasize the importance of obesity management to men or women aged ≥ 60 years, specifically.

Résumé
Objectives@#The Korea Centers for Disease Control and Prevention has published “A Guideline for Unknown Disease Outbreaks (UDO).” The aim of this report was to introduce tabletop exercises (TTX) to prepare for UDO in the future. @*Methods@#The UDO Laboratory Analyses Task Force in Korea Centers for Disease Control and Prevention in April 2018, assigned unknown diseases into 5 syndromes, designed an algorithm for diagnosis, and made a panel list for diagnosis by exclusion. Using the guidelines and laboratory analyses for UDO, TTX were introduced. @*Results@#Since September 9th , 2018, the UDO Laboratory Analyses Task Force has been preparing TTX based on a scenario of an outbreak caused by a novel coronavirus. In December 2019, through TTX, individual missions, epidemiological investigations, sample treatments, diagnosis by exclusions, and next generation sequencing analysis were discussed, and a novel coronavirus was identified as the causal pathogen. @*Conclusion@#Guideline and laboratory analyses for UDO successfully applied in TTX. Conclusions drawn from TTX could be applied effectively in the analyses for the initial response to COVID-19, an ongoing epidemic of 2019 - 2020. Therefore, TTX should continuously be conducted for the response and preparation against UDO.

PURPOSE: With the increase of foreigners using Korea health facilities, it is important for nurses to be culturally competent. Thus, the purpose of this study was to examine the effects of a cultural competence educational program on the cultural competence of nursing students. METHODS: A quasi-experimental study with a non-equivalent control group pretest-posttest design was used. For the experimental group there were 42 participants from one school and for the control group, 40 from another school. The experimental group participated in the 14 week multicultural nursing education program while the control group participated later after the experiment was finished. Data were collected using self-report structured questionnaires prior to the intervention and right after the intervention, and were analyzed using descriptive statistics, χ² test, and independent t-test with SPSS 18.0 program. RESULTS: The experimental group reported significant positive changes for cultural knowledge (t=3.99, p<.001), cultural awareness (t=3.92, p<.001), cultural acceptance (t=2.25, p=.027), and cultural competence behaviors (t=4.30, p<.001) compared to the control group. CONCLUSION: The results of the study indicate that the cultural competence educational program developed by the researchers is effective in raising the level of cultural knowledge, cultural awareness, cultural acceptance, and cultural competence behaviors of nursing students.

PURPOSE: Transglutaminase 4 (TGase 4) belongs to a family of enzymes that catalyzes the post-translational modification of proteins. In an attempt to establish its physiological function(s), the distribution of TGase 4 expression in the human eye was determined. METHODS: Ocular tissues obtained from five human whole eyeball postmortem (40(+1) weeks at gestation age, 2 months, 48, 66, 76 years) were stained with monoclonal antibodies against human TGase 4 using indirect immunohistochemical method. RESULTS: TGase 4 was found in the lacrimal glands, corneal epithelium and endothelium, conjunctival epithelium, lens epithelium, retina (inner segment of photoreceptor, external limiting membrane, outer plexiform layer, inner plexiform layer, retinal nerve fiber layer and internal limiting membrane), iris, ciliary muscle, ciliary nonpigmented epithelium and trabecular meshwork. Endothelium of blood vessels in all ocular tissues was also stained. Conjunctival stroma, choroid, anterior tenon's capsule were faintly stained. No evidence of immunostaining for TGase 4 was found in the corneal stroma, iris stroma, lens nucleus, ciliary process, sclera, extraocular muscle and optic nerve. CONCLUSIONS: The expression pattern of TGase 4 was different from those of other TGase isoforms in the human eye. This result may be helpful in further investigation of the role of TGase 4 in the ocular tissue.
