PURPOSE: This study aims to review the appropriateness of the issued death certificates and autopsy reports and to evaluate the improvement points of these documents in accordance with the guidelines of the Korean Medical Association and the National Statistical Office. Moreover, this study also examines why the guideline is necessary for the credibility of these documents. METHODS: The death certificates and autopsy reports written by a training hospital were analyzed for a 12-month period, between December 2014 and November 2015. The reference to analysis was the “guidelines to medical certificate 2015” written by the Korean Medical Association, “World Health Organization (WHO) death certificate principle”, and “guideline leaflet,” as provided by the National Statistical Office. Two researchers analyzed the documents that were against the guidelines, and suggested improvement points. The analyzed variables were age, sex, issued date, direct cause of death, manner of death, location of death, and types of accident. The primary goal was to see the rate of issued documents written correctly according to the guidelines and to suggest possible improvement points. The secondary goal was to analyze the reason for accordance and discordance between researchers. RESULTS: There were a total of 603 death certificates and autopsy reports issued during the research period; 562 (93.2%) and 41 (6.8%) cases, respectively. As for the manner of death, 521 cases were “death from disease,” 64 were “external causes,” and 18 were “others or unknown” (86.4%, 10.6%, and 3.0%, respectively). As for the issued department, internal medicine and emergency medicine issued 301 (49.9%) and 126 (20.9%) documents, respectively. Of these, 139 (23.1%) cases were regarded to be in accordance with the guidelines, while 304 (50.4%) were considered to be discordant cases. Among the discordant cases, there were 177 (29.4%) cases that were the mode of death directly written to cause of death. As for the records of “period of occurrence to death” were recorded only 70 (11.7%) cases (including “unknown” 65 cases) and the others were blank. The Kappa number of analysis regarding the evaluation correspondence of the two researchers was 0.44 (95% confidence interval, 0.38 to 0.51). CONCLUSION: The most frequent error was ‘the condition of death to direct cause of death’ with the ratio of 29.4%. This may have been because the rate of concordance between the researchers based on the guidelines was not high enough. There is a need to provide specific guidelines for each case, and also promote and educate regarding significant errors.

PURPOSE: This study aimed to collect information that is needed to develop interprofessional education curricula by examining the current status of interprofessional conflicts and the demand for interprofessional education. METHODS: A total of 95 doctors and 92 nurses in three university hospitals in Seoul responded to a survey that comprised questions on past experience with interprofessional conflicts, the causes and solutions of such conflicts, past experience with interprofessional education, and the demand for interprofessional education. RESULTS: We found that 86% of doctors and 62.6% of nurses had no interprofessional education experience. Most of them learned about the work of other health professions naturally through work experience, and many had experienced at least one interprofessional conflict. For doctors, the most popular method of resolving interprofessional conflicts was to let the event pass; for nurses, it was to inform the department head. Further, 41.5% of doctors and 56.7% of nurses expressed no knowledge of an official system for resolving interprofessional conflicts within the hospital, and 62.8% of doctors and 78.3% of nurses stated that they would participate in interprofessional education if the opportunity arose. CONCLUSION: In Korean hospital organizations, many doctors and nurses have experienced conflicts with other health professionals. By developing an appropriate curriculum and educational training system, the opportunities for health professionals to receive interprofessional education should expand.

PURPOSE: Abdominal computed tomography (CT) is a widely recognized method to diagnose patients with acute abdominal pain in the emergency departments (EDs). We aimed to investigate the current state and interpretations of abdominal CT performed in the ED of a tertiary university hospital. METHODS: This was a retrospective study based on an abdominal CT database and medical records of patients over 15 years of age, who had visited our ED between January 1 and December 31, 2013. The data collected included CT types, final interpretations, characteristics of the patients, and location of pain at the time of CT. RESULTS: A total of 1,978 abdominal CTs were performed among 1,923 patients during the research period. The most frequent organs involved in the major diagnosis were those in the urinary system, followed by the appendix, liver, large intestine, and gallbladder. The most frequently interpreted diagnoses in these organs were in the order of urinary stone, appendicitis, liver cirrhosis, infectious colitis, and acute cholecystitis. The most frequent location of pain was the right lower quadrant (429 cases, 21.7%), and the most frequently performed CT types were contrast-enhanced abdominal and pelvic CT (1,260 cases, 63.7%). CONCLUSION: Various interpretations were derived based on the abdominal CTs, ranging from critical to mild diseases and from common to rare diseases. Based on this study, we have developed a preliminary interpretation checklist for abdominal CTs.

Estradiol (17β-estradiol) is synthesized primarily in the gonads of both sexes and regulates the development and function of reproductive organs. Recently, we reported that intestinal lymphocyte homeostasis is regulated by estradiol synthesized de novo in the endothelial cells of the high endothelial venules (HEVs) of mesenteric lymph nodes and Peyer's patches in mice. This observation prompted us to hypothesize that HEVs of intestinal lymphoid tissues are sites of estradiol synthesis across species. In this study, we examined whether estradiol is synthesized in the intestinal lymphoid tissues of adolescent piglets. Comparisons of estradiol levels in blood and tissue showed that estradiol concentrations in mesenteric lymph nodes and Peyer's patches were significantly higher than the level in serum. Reverse transcription polymerase chain reaction showed that porcine intestinal lymphoid tissues express mRNAs for steroidogenic enzymes (StAR, 17β-Hsd, 3β-Hsd, Cyp17a1, and Cyp19a1), and immunohistochemical results in ilial tissue showed expression of aromatase (CYP19) in Peyer's patch-localized endothelial cells of HEVs. When mesenteric lymph node and Peyer's patch tissues were cultured in vitro, they produced estradiol. Taken together, the results indicate that mesenteric lymph nodes and Peyer's patches are sites of estradiol synthesis in adolescent piglets.

Background: Positive fecal immunochemical test (FIT) results have been recently suggested as a risk factor for systemic inflammation. Diabetes induces inflammation in the gastrointestinal tract via several ways. We investigated the association between FIT results and the incidence of diabetes. Methods: A total of 7,946,393 individuals aged ≥50 years from the National Cancer Screening Program database who underwent FIT for colorectal cancer (CRC) screening from 2009 to 2012 were enrolled. The primary outcome was newly diagnosed diabetes based on the International Classification of Disease 10th revision codes and administration of anti-diabetic medication during the follow-up period. Results: During a mean follow-up of 6.5 years, the incidence rates of diabetes were 11.97, 13.60, 14.53, and 16.82 per 1,000 personyears in the FIT negative, one-positive, two-positive, and three-positive groups, respectively. The hazard ratios (HRs) for the incidence of diabetes were 1.14 (95% confidence interval [CI], 1.12 to 1.16; HR, 1.21; 95% CI, 1.16 to 1.27; and HR, 1.40; 95% CI, 1.28 to 1.55) in the one-positive, two-positive, and three-positive FIT groups compared with the FIT negative group, respectively. The effect was consistent in individuals with normal fasting blood glucose (adjusted HR 1.55 vs. 1.14, P for interaction <0.001). Conclusion Positive FIT results were associated with a significantly higher risk of diabetes, suggesting that the FIT can play a role not only as a CRC screening tool, but also as a surrogate marker of systemic inflammation; thus, increasing the diabetes risk.
