The objective of the current pilot study was to evaluate the reproductive performance and health indicators in Dorper, White Dorper, and Tsigai breed ewes managed semi-intensively under European temperate conditions. A total of 544 ewe-year units were observed, with ewes (ranging from 1.5 to 8 years of age) managed under identical rearing conditions for a period of two consecutive production cycles (2012 through 2013 and 2013 through 2014). In general, significant ($p{\leq}0.001$) genotype-related disparities were found in occurrence rates for all health parameters taken into study. Clinical mastitis incidence was significantly lower ($p{\leq}0.05$) in Dorper (9.4%) and White Dorper (10.8%) breeds compared to that of Tsigai ewes (17.4%). Significant differences ($p{\leq}0.05$) for lameness were found between Dorper and Tsigai breeds, with occurrence rates of 8.0% and 2.9%, respectively. Incidence for pneumonia and abortion was not influenced (p>0.05) by the ewes' genotype. Litter size was significantly lower ($p{\leq}0.05$) in White Dorper breed than for Dorper and Tsigai ewes, of 1.21, 1.40, and 1.45, respectively. Conception rates and lambs survival were not affected (p>0.05) by genotype. Results suggest that South African Dorper and White Dorper sheep breeds have adapted well to the specific rearing conditions.

Purpose : For the past 10 years, the incidence of thyroid cancer has been rapidly increased in female population showing current incidence of 12,000 new thyroid cancer patients annually in Korea. Though differentiated thyroid cancer is known to show favorable prognosis and excellent long-term survival from slow growth and late distant metastasis, we re-evaluated prognostic factors of recurrence and mortality following surgical procedures based on our cases. Material and Methods : 954 Patients of DTC surgically treated at Department of Surgery, Inje University Busan Paik Hospital between 1980 and 2004 were reviewed in the aspects of the surgical procedures, clinical staging, risk factors, recurrence and their outcome through median follow-up period of 10.5 years. Results : Recurrence in remnant thyroid, cervical nodes, and distant metastasis were observed in 84 paients(8.8%), and 31 patients were confirmed to be died of locoregional recurrence of cancer and distant metasasis. Regarding the risk factors to recurrence, tumor size, extrathyroidal extension, nodal metastasis, and capsular invasion were significant predictors(p<0.05). Local recurrence and distant metastasis had no statistical signiicance according to age, sex, pathology, surgery, and lymphovascular invasion. Overall 10-year survival rate was 92.4%, but low, intermediate, and high-risk patient showed 100%, 94.4%, and 70.5% respectively. Conclusion : The significant factors influencing local recurrence and distant metastasis were tumor size, extrathyroidal exension, LN metastasis, capsular invasion. In order to improve survival rate of high-risk group, appropriate and aggressive management should be recommended.

Based on a literature review regarding shift work, it is recognized that it has an adverse effect on workers' health. Especially, the night shift rather than the day shift imposes severe disorders on workers, which are indicated to dyssomnia, maladaptation to social life, and health problems such as gastroenteric trouble, cardiovascular diseases and depression. As the shift work can be explainable by using workers' labor ability necessarily to maintain company business consistently, it does not consider biorhythm, active mass and health condition of workers Actually duration of shit work would deprive workers of fundamental life rights by causing physical and mental effects. As a result of reviewing previous case studies related to effect of work pattern (day shift and night shift) on workers' health, an incidence of physical diseases like dyssomnia, gastroenteric trouble, cardiovascular diseases and premature delivery was higher in shift workers than normal workers. Additionally the incidence of mental disorders such as busy brain, social isolation, depression and work stress was also higher in shift workers than normal workers. These adverse physical and mental problems were intensified to night shift workers compared to day shift workers. Considering current various reports and study results, it is recommended that the shift work, especially the night work pattern, should not apply to contemporary work situation for sustaining workers' health condition constantly.

Background/Aims: The association between metabolic syndrome and colorectal cancer (CRC) has been suggested as one of causes for the increasing incidence of CRC, particularly in younger age groups. The present study examined whether the current age threshold (50 years) for CRC screening in Korea requires modification when considering increased metabolic syndrome. Methods: We analyzed data from the National Health Insurance Corporation database, which covers ~97% of the population in Korea. CRC risk was evaluated with stratification based on age and the presence/absence of relevant metabolic syndrome components (diabetes, dyslipidemia, and hypertension). Results: A total of 51,612,316 subjects enrolled during 2014 to 2015 were analyzed. Among them, 19.3% had diabetes, hypertension, dyslipidemia, or some combination thereof. This population had a higher incidence of CRC than did those without these conditions, and this was more prominent in subjects <40 years of age. The optimal cutoff age for detecting CRC, based on the highest Youden index, was 45 years among individuals without diabetes, dyslipidemia, and hypertension. Individuals with at least one of these components of metabolic syndrome had the highest Youden index at 62 years old, but the value was only 0.2. Resetting the cutoff age from 50 years to 45 years achieved a 6% increase in sensitivity for CRC detection among the total population. Conclusions: Starting CRC screening earlier, namely, at 45 rather than at 50 years of age, may improve secondary prevention of CRC in Korea.

Background: Acute pyelonephritis (APN) is one of the most common community-acquired bacterial infections. Recent increases of antimicrobial resistance in urinary pathogens might have changed the other epidemiologic characteristics of APN. The objective of this study was to describe the current epidemiology of APN in Korea, using the entire population. Methods: From the claims database of the Health Insurance Review and Assessment Service in Korea, the patients with International Classification of Diseases, 10th Revision codes N10 (acute tubulo-interstitial nephritis) or N12 (tubulo-interstitial nephritis, neither acute nor chronic) as the primary discharge diagnosis during 2010-2014 were analyzed, with two or more claims during a 14-day period considered as a single episode. Results: The annual incidence rate of APN per 10,000 persons was 39.1 and was on the increase year to year (35.6 in 2010; 36.7 in 2011; 38.9 in 2012; 40.1 in 2013; 43.8 in 2014, P = 0.004). The increasing trend was observed in both inpatients (P = 0.014) and outpatients (P = 0.004); in both men (P = 0.042) and women (P = 0.003); and those aged under 55 years (P = 0.014) and 55 years or higher (P = 0.003). Eleven times more women were diagnosed and treated with APN than men (men vs. women, 6.5 vs. 71.3), and one of every 4.1 patients was hospitalized (inpatients vs. outpatients, 9.6 vs. 29.4). The recurrence rate was 15.8%, and the median duration from a sporadic episode (i.e., no episode in the preceding 12 months) to the first recurrence was 44 days. The recurrence probability increased with the number of previous recurrences. The average medical cost per inpatient episode was USD 1,144, which was 12.9 times higher than that per outpatient episode (USD 89). Conclusion: The epidemiology of APN in Korea has been changing with an increasing incidence rate.

Purpose : The first case of coronavirus disease-2019 (COVID-19) disease outbreak in Korea occurred in January 2020, and the cumulative number of confirmed cases by the Central Defense Response Headquarters of the Quality Management Administration as of November 30 was 34,201. Looking at the incidence trend of domestic confirmed cases by age, the incidence rate of COVID-19 in the age group of 20-29 years, which corresponds to college students, was 27.4 %, the highest compared by age group. Considering the current status of the infection rate, universities will become the centers of new COVID-19 cases if face-to-face lectures are recommenced without preparatory measures and analysis of infection prevention (e.g., infection awareness and education for university students). Thus, this study intended to investigate the level of knowledge, educational needs, and preventive behavior performance of college students about COVID-19 and provide basic data for the development of an education program for the prevention of COVID-19 for college students. Methods : This study is a descriptive correlational study aimed to investigate the correlation between knowledge about COVID-19, educational needs, and degree of preventive behavior performance in 407 college students attending one University in Gyeonggi-do. Results : The subjects' knowledge score about COVID-19 was 12.46±1.39 points, average educational needs score was 29.16±3.14 points, and prevention behavior performance survey result was 35.50±3.61 points. Moreover, positive correlation was observed between the knowledge about COVID-19 and educational needs (r=.203, p<.001) and knowledge and preventive behavior performance (r=.140, p=.005). Further, educational needs and preventive behavior performance demonstrated a statistically significant positive relationship (r=.311, p<.001). Conclusion : Therefore, organizing an educational program to acquire accurate knowledge is necessary to make it a habit for college students to practice preventive behavior against COVID-19.

This study provides a comprehensive analysis of the epidemiological trends and challenges in managing tuberculosis (TB) in livestock in Korea from 2013 to 2022. Tuberculosis, caused by the Mycobacterium tuberculosis complex, is a significant zoonotic disease affecting cattle, deer, and other domesticated animals. Despite the initiation of a test-and-slaughter eradication policy in 1964, TB has continued to persist in Korean livestock, particularly in cattle and deer. This study used data from the Korea Animal Health Integrated System and provincial animal health laboratories to analyze TB incidence in various livestock including different cattle breeds and deer species. The results from 2013 to 2022 showed a peak in TB cases in 2019 with a subsequent decline by 2022. The study highlighted a significant incidence of TB in Korean native cattle and the need for amore inclusive approach towards TB testing and control in different cattle breeds. Additionally, the study underscored the importance of addressing TB in other animals such as goats, wildlife, and companion animals for a holistic approach to TB eradication in Korea. The findings suggest that while the test-and-slaughter strategy has been historically effective, there is a need for adaptation to the current challenges, and learning from successful eradiation stories on other countries like Australia. A collaborative effort involving an expanded surveillance system, active private sector participation, and robust government support essential for the efficient eradication of TB in livestock in Korea.

Background: Pre-operative ilioinguinal-iliohypogastric nerve block (II-IHNB) has a proven role in lessening acute postoperative pain and opioid consumption following hernia repair. However, its role in preventing post-herniorrhaphy groin pain (PHGP) is still unknown. The current study aims to assess pre-operative II-IHNB's impact on PHGP three and six months after open inguinal hernia repair under spinal anesthesia. Methods: Seventy patients posted for inguinal hernia surgery were randomly allocated into group A (received ultrasound-guided II-IHNB with 10 mL of 0.5% ropivacaine and 4 mg [1 mL] dexamethasone) and group B (received ultrasound-guided II-IHNB with 11 mL of 0.9% normal saline). The time to first analgesic request, pain scores, opioid consumption, DN4 score, and PHGP at 3 and 6 months were analyzed using appropriate statistical tests. Results: The numerical pain rating scale at movement in group A was significantly reduced at all the time intervals of 3, 6, 12, and 24 hours compared to group B. Total opioid usage was lower in group A (3.71 mg [3.90]) versus group B (12.14 mg [4.90]) with a mean difference of -8.43 mg (95% CI -10.54, -6.32), P < 0.001. The time required for the first rescue analgesic was significantly longer in group A (360 min [180-360]) versus (180 min [180-360]) in group B (P < 0.001). However, there was no difference in the incidence of PHGP at three and six months between the two groups. Conclusions: Pre-operative ultrasound-guided II-IHNB reduces postoperative analgesic requirement but does not reduce the incidence of chronic PHGP following hernia surgery at 6 months.

Adverse drug reactions (ADRs) are closely associated with increased morbidity and mortality rates, prolonged hospitalization durations, and higher healthcare costs. This study aimed to estimate the incidence, clinical features, and reporting status of ADRs to improve the current ADR reporting system and prevent recurrent ADRs in hospitals. This retrospective study was conducted at a regional referral hospital. Patients diagnosed with ADRs over a 5-year period (2009-2014) were recruited for this study. An ADR was identified as an ADR-related diagnosis in a patient's medical record or an ADR registered through the in-hospital ADR reporting system. The incidence, culprit drug, clinical manifestations, reporting source, severity, related management, and recurrence rate were assessed. Among 1,112 patients, 1,375 ADR events were collected, an estimated 0.06% of the total number of patient visits. Diagnostic contrast agents (46.4%) were the most common culprit drugs, followed by antibiotics (22.0%), nonsteroidal anti-inflammatory drugs (9.9%), and opioids (4.5%). Skin reactions (67.5%) such as rashes and hives were the most frequent manifestations. Additional ADR-related medical attention was necessary in two thirds of cases. One hundred eighty ADR events (13.1%) were categorized as severe, and 19 patients (1.4%) experienced re-exposure to the culprit drugs. Four patients (0.3%) experienced fatal ADRs. Physicians were the most frequent ADR reporters in the in-hospital ADR reporting system. In conclusion, many ADR events may be overlooked, and re-exposure to causative drugs commonly occurs. Continuous education and maintenance of a reporting system may be important for preventing recurrent ADRs.
