Daegu (the city in South Korea) who visited a medical institution for medical checkup in 2016. The urine cotinine test strip (DCT-102; CLIAwaived Inc., cut-off value = 200 ng/mL) was used to classify the actual smoking status and to assess the validity of self-reported smoking status on questionnaires. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of the smoking questionnaires were analyzed. Subjects testing positive in the urine cotinine test (assumed the actual current smokers) were selected. The frequency at which actual current smokers were misclassified as current non-smokers by the questionnaire was calculated. Subjects' characteristics were analyzed for possible association with any discrepancy between self-reported smoking status and urine cotinine test results.RESULTS: The smoking rates among firefighters surveyed using the smoking questionnaire and the urine cotinine test were 22.47% and 51.24%, respectively. Of the all subjects, 29.66% (n = 132) were misclassified. The sensitivity of the smoking questionnaire was 42.98%, the specificity was 99.08%, the PPV was 98.00%, and the NPV was 62.32%. In the 228 subjects classified as current actual smokers by the urine cotinine test, 57.02% (n = 130) were misclassified on the questionnaire. The misclassification rate increased with age. The degree of misclassification also increased when subjects had a history of disease.CONCLUSIONS: In present study, the validity of the smoking questionnaire for firefighters was not suitable for investigating smoking status due to low sensitivity. To increase the validity of smoking status monitoring in firefighters, consideration of the various factors like survey environment, subjects' characteristics, and occupational factors is needed.]]>

2.Comparison of Salinity and Sodium Content by the Salinity Measurement Frequency of Soups of Childcare Centers Enrolled in the Center for Children's Food Service Management in Daegu
Korean Journal of Community Nutrition 2020;25(1):13-20
OBJECTIVES: This study examined the salinity of soups provided at childcare centers by measuring the salinity for three years and providing basic data for sodium reduction.METHODS: The soup salinity was measured using a Bluetooth salinity meter from January 2015 to December 2017 at 80 childcare foodservice establishments enrolled in the Suseong Center for Children's Foodservice Management in Daegu.RESULTS: An analysis of the soup salinity each year showed that the salinity decreased significantly from 0.48% in 2015 to 0.41% in 2017, particularly in clear soups and soybean soups compared to other soups (P < 0.05). The salinity and sodium content in seafood soups (0.45% and 179.1 mg/100 g, respectively) were highest, followed by soybean soups (0.44%, 175.2 mg/100 g), with perilla seed soups containing the lowest (0.42%, 167.2 mg/100 g) (P < 0.05). The salinity was significantly higher in institutional foodservice establishments than small foodservice establishments (P < 0.001). The salinity and sodium content were the highest in foodservice establishments with a small number of measurements, and the salinity was the lowest in foodservice establishments with salinity measurements performed an average of 151 times each year (three times a week) or more (P < 0.05). The soup salinity was low in the order of winter, spring, summer, and autumn, and the salinity decreased significantly year by year in all seasons. (P < 0.05).CONCLUSIONS: The soup salinity was significantly lower in foodservice establishments where the salinity was measured more than three times a week, indicating that continuous salinity management is effective.

The purpose of this study was 2-fold: 1) to investigate the prevalence of gastrointestinal parasite infection in cats reared in Daegu, Republic of Korea and 2) to assess the efficacy and safety of a topical emodepside/praziquantel formulation for cats with parasitic infections. The gastrointestinal parasite infections were examined microscopically using the flotation method. Of 407 cats, 162 (39.8%) were infected by at least one gastrointestinal parasite, including Toxocara cati (63.0%), Toxascaris leonina (31.5%), Taenia taeniaeformis (3.7%), and Cystoisospora felis (1.9%). None of the infected animals had multiple infections. When the data were analyzed according to sex, age, and type of cat, stray cats showed statistically higher prevalence than companion cats (P<0.05). On the 5th day after treatment, no parasitic eggs were detected using microscopic examination. In addition, no adverse effects, such as abnormal behaviors and clinical symptoms, were observed in the cats treated with the drug. These results quantify the prevalence of gastrointestinal parasites in cats in Daegu, Republic of Korea, and show that topical emodepside/praziquantel is a safe and effective choice for treating the parasitic infections in cats.

From October 2015 to August 2018, tapeworm proglottids were obtained from 10 patients who were residents of Daegu and Gyeongbuk provinces and had a history of raw beef consumption. Most of them had no overseas travel experience. The gravid proglottids obtained from the 10 cases had 15–20 lateral uterine branches. A part of internal transcribed spacer 1 (ITS1) DNA of the 10 cases, amplified by polymerase chain reaction (PCR) and digested with AleI restriction enzyme, produced the same band pattern of Taenia saginata, which differentiated from T. asiatica and T. solium. Sequences of ITS1 and cytochrome c oxidase subunit 1 (cox1) showed higher homology to T. saginata than to T. asiatica and T. solium. Collectively, these 10 cases were identified as T. saginata human infections. As taeniasis is one of the important parasitic diseases in humans, it is necessary to maintain hygienic conditions during livestock farming to avoid public health concerns.

5.Endovascular Aneurysm Repair by Combining Different Endografts: the Zenith Body and Endurant Limbs
Vascular Specialist International 2019;35(1):10-15
PURPOSE: There are several commercially approved stent grafts in Korea for the treatment of abdominal aortic aneurysms (AAAs). Each device has its advantages and disadvantages based on the patient’s anatomy and the clinical situation. The Zenith device allows accurate and precise endograft placement, whereas the Endurant device has improved flexibility and trackability. We reviewed 5 cases in which a combination of the Zenith main body and the Endurant iliac limb was used. MATERIALS AND METHODS: From January 2010 to February 2015, 90 patients with AAA underwent endovascular aneurysm repair (EVAR) using the Zenith body at Daegu Catholic University Hospital. Among them, 5 patients who underwent EVAR with the Zenith body and Endurant iliac limb were included in this study. RESULTS: The mean age of the patients was 74.20±3.35 years. All patients were men. The main reason for use of the Endurant iliac limb was aortoiliac angulation. Type III endoleak, stent migration, and stent kinking were not noted. Comparing 85 patients who received a Zenith endograft with 5 patients who received the hybrid endograft, there were no statistical differences in clinical characteristics, intraoperative details and post procedural complications. The mean admission duration was 19.00±13.60 days, and the mean follow-up duration was 1,018.11±925.34 days. In the hybrid endograft group, there was no mortality during the follow-up duration. CONCLUSION: Although the material, radial force, diameter, and length of the overlap zone differ between the two devices, EVAR with the hybrid endograft is safe and effective.

Journal of Korean Academy of Oral Health 2019;43(1):3-7
OBJECTIVES: This study was conducted to analyze the effect that oral health literacy of adults has on perceived oral health state and to identify the factors that affect perceived oral health status. METHODS: A self-administered questionnaire survey was distributed to 554 adults who lived in the Daegu or Gyeongbuk areas and visited dental institutions located in the Daegu area. For adults who were 60 years old or older, direct interviews were conducted. Statistical analysis was performed with t-tests, analysis of variance, and multiple regression using SPSS RESULTS: Between oral health literacy and perceived oral health status, a significant positive correlation was revealed (r=0.142, P<0.01). A significant positive correlation was revealed between oral health literacy and knowledge (r=0.397, P<0.01). A significant but weakly positive correlation was revealed between oral health knowledge and perceived oral health status (r=0.086, P<0.05). To identify factors affecting perceived oral health status, multiple regression analysis was conducted, and the result showed that oral health literacy was a statistically significant factor (β=0.105, p<0.05). Among general characteristics, age was a statistically significant negatively affecting factor, as it showed a negative relationship with perceived oral health status (β=−0.140, P=0.001, adjusted R2=0.049). CONCLUSIONS: When these study results are taken into consideration, oral health literacy is a factor affecting perceived oral health status, and as such, oral health literacy of the research targets should be taken into consideration when implementing oral health education to promote oral health.

7.Significance of Knife Tip Injuries as Hesitation Marks
Korean Journal of Legal Medicine 2019;43(1):7-15
Hesitation wounds are tentative, superficial incised wounds around the fatal wound(s). This study aimed to investigate the frequency and characteristic features of hesitation wounds including ordinary incised wounds and knife tip injuries as hesitation marks from the autopsy cases of suicides using sharp force instruments. The subjects were 478 cases out of 3,131 suicide cases autopsied at the Department of Forensic Medicine, School of Medicine, Kyungpook National University in Daegu, from August, 2001 to 2013. 48 cases (approximately 10%) were suicides using sharp force instruments. In 27 cases (56.3%), the sharp force was successfully applied causing suicide; 17 cases (35.4%) were so called complex suicide cases, in which two or more different methods including sharp force injury were used; and the 4 remaining cases were suicides caused by other reasons. Overall hesitation wounds had a high frequency of 33/48 cases (68.8%). The frequency of cases in which knife tip injuries were found was lower, appearing in 13/33 cases (39.3%). The most preferred sites of knife tip injuries were the abdomen (9 cases), neck (4 cases), chest (3 cases), and face (1 case) in these 13 cases, including several overlapped cases. The average number of knife tip injuries was 14.6. A total of 88.2% of knife tip injuries was found near the incised hesitation wounds or fatal wounds. In conclusion, knife tip injuries may be a significant factor in identifying hesitation wounds, and they should be precisely examined and evaluated during autopsies to determine the manner of death.

OBJECTIVES: This study examined the status of children's favorite foods intake and the relationship with the policy environment based on the Special Act on Safety Control of Children's Dietary Life for suggesting a supportive policy strategy. METHODS: The subjects were 4th grade students (n=1,638) in elementary school from 45 schools collected from seven areas (Seoul, Daegu, Daejeon, Gyeonggi, Chungnam, Jeonbuk, and Gyeongnam). The children participated in a self-administered questionnaire survey in class under the supervision of the teacher. The questionnaire consisted of items, such as social demographic characteristics, frequency of intake of the children's favorite foods, and policy cognition. A t-test and ANOVA were applied to explore the relationship between the frequency of children's favorite foods intake and policy cognition. The survey was implemented from August 2016 to September 2016. RESULTS: For the boys, the frequency of ‘high-calorie low nutrient foods intake’ (HCLN) was significantly higher than that of the girls (p<0.01). For the children who received information on their favorite foods from the internet, the frequency of HCLN was higher than the other sources (p<0.01). The time of TV viewing and computer usage, and smartphone usage was associated with a higher frequency of HCLN, and a lower healthy favorite food intake (all p<0.001). The intake frequency of healthy favorite foods indicated a positive correlation with the policy cognition, including policy perception, usefulness, necessity and buying intention, and educational experience. CONCLUSIONS: This study showed a correlation with the frequency of children's favorite foods intake and policy. In particular, the frequency of children's healthy favorite foods intake indicated a meaningful relationship with the policy than the frequency of HCLN. This study also found that the consumption of children's healthy favorite foods was positively correlated with the educational experience. To develop a supportive policy for a good dietary environment for children, there is a need to focus on how to collaborate with multiple levels of influences, such as the national level, school level, and family.

Journal of the Korean Neurological Association 2019;37(3):262-268
BACKGROUND: The objective of this study was to quantify the sleep behavior of Korean high-school students and its relationship with academic performance. METHODS: Sleep surveys were completed by high-school students in Daegu, South Korea during September 2017. The questionnaires investigated factors such as sleep quality, sleep and wake schedules, nighttime smartphone use, and scores on a five-level grading scale pertaining to academic performance (A, 1–20%; B, 21–40%; C, 41–60%; D, 61–80%; E, 81–100%). The chi-squared test, independent t-test, analysis of variance, and regression analysis were used to analyze the results. RESULTS: The questionnaires were completed by 691 high-school students consisting of 279 (40.4%) boys and 412 (59.6%) girls. Poor sleep quality (Pittsburgh Sleep Quality Index [PSQI] ≥8.5) was identified in 111 (16.1%) students, and depressed mood (Hospital Depression Scale score ≥8) was identified in 254 (36.8%). Students with better academic performance tended to have lower PSQIs (A, 5.29±2.58; B, 5.41±2.98; C, 6.00±2.65; and D/E, 6.15±2.97), and the morningness-eveningness questionnaire scores were significantly higher in A-level students than in D- and E-level students. Regression analysis showed that leaving school early each day and greater nighttime smartphone use were significantly associated with worse academic performance in high-school students. CONCLUSIONS: This study found a close relationship between the sleep behavior of students and their academic performance. Students with better sleep quality, morningness, and less nighttime smartphone use tended to perform better academically. Lifestyle modification should be considered as an important factor for improving academic performance.
