The Oriental stork (Ciconia boyciana), an endangered species, faces significant threats despite extensive conservation efforts aimed at their reintroduction and long-term survival in South Korea. Understanding the primary causes of mortality and identifying predominant pathological lesions are crucial for enhancing these efforts. This study aimed to investigate the causes of unexplained mortality in Oriental storks between 2019 and 2023 through comprehensive postmortem examinations. Twelve storks, including both wild and captive birds, classified as “unknown“ deaths, were examined. The results revealed that parasitic infections, particularly in wild storks, were frequently observed (41.7%). Additionally, gastrointestinal obstruction due to the ingestion of foreign materials was identified in a wild stork, highlighting the impact of environmental pollution. Despite the prevalence of inflammatory lesions in liver (58.3%), no cases of hepatitis were confirmed, except for one case of liver rupture in a wild stork. Notably, three nestling death cases from a single litter of captive storks suggested potential parental infanticide or lack of parental care. The overall results highlight the importance of addressing parasitic infections and environmental risks to improve the survival of wild Oriental storks, and emphasize the need for effective management in breeding facilities. Continuous monitoring and pathological evaluations for mortality cases are essential for understanding disease trends and developing adaptive conservation strategies to ensure the long-term preservation of this endangered species.

Objective: Many trauma centers use their own criteria for major trauma patients, and these criteria are organized according to physiological causes and their related mechanisms. Mechanism related criteria have high sensitivity but low specificity. We confirmed 20 feet as a single factor for trauma team activation criteria. Methods: This study was retrospectively conducted in the Pusan National University Hospital trauma center, which is a level 1 trauma center in Busan. Patients were grouped as group 1, a fall from less than 20 feet; and group 2, a fall from more than 20 feet. We compare the two groups of prognostic factors using logistic regression analysis. Results: The relationship between the height of the fall and the patient’s prognosis showed a positive relationship on the logistic regression analysis. Yet the cut-off value of a 20 foot height showed poor predictive power for the patient’s prognosis. Conclusion In conclusion, as trauma team activation criteria, a 20 foot height seems to be a reasonable aspect of patients’ clinical prognosis between above 20 feet and below 20 feet. Yet it seems to be controversial as a cut-off value. Thus, more studies will be needed to identify a specific height for trauma team activation.

BACKGROUND/AIMS: Proton pump inhibitors (PPIs) act by irreversibly binding to the H+-K+-ATPase of the proton pump in parietal cells and may possibly affect the vacuolar H+-ATPase in osteoclasts. METHODS: We investigated the effect of 8 weeks of PPI treatment on the parameters of bone turnover and compared PPI with revaprazan, which acts by reversibly binding to H+-K+-ATPase in proton pumps. This study was a parallel randomized controlled trial. For 8 weeks, either a PPI or revaprazan was randomly assigned to patients with gastric ulcers. The parameters of bone turnover were measured at the beginning of and after the 8-week treatment period. RESULTS: Twenty-six patients (PPI, n=13; revaprazan, n=13) completed the intention-to-treat analysis. After the 8-week treatment period, serum calcium and urine deoxypyridinoline (DPD) were increased in the PPI group (serum calcium, p=0.046; urine DPD, p=0.046) but not in the revaprazan group. According to multivariate linear regression analysis, age > or =60 years was an independent predictor for the changes in serum calcium and urine DPD. CONCLUSIONS: In elderly patients, administering a PPI for 8 weeks altered bone parameters. Our study suggested that PPIs might directly alter bone metabolism via the vacuolar H+-ATPase in osteoclasts.

This study was conducted to estimate the prevalence rates and to explore associated factors of sarcopenic obesity (SO) in 2,221 Koreans over 60 yr-of age from the Fourth Korea National Health and Nutrition Examination Survey (2009). Participants were assessed by dual energy X-ray absorptiometry. Appendicular skeletal muscle mass divided by body weight was used to define sarcopenia and waist circumference was used to define obesity. We estimated the prevalence rates of SO according to age-groups, sex and region. In addition, each group was compared by demographic characteristics, metabolic status, nutrition, and physical activity. The prevalence rates of SO were 6.1% (95% confidential interval [CI] = 6.1-6.2) for men and 7.3% (95% CI = 7.3-7.3) for women, respectively. SO was positively associated with no current working and the number of combined medical conditions. High serum insulin level was positively associated with SO, whereas vitamin D was negatively associated with SO in both men and women. In conclusion, the prevalence rates of SO are 6.1% in men and 7.3% in women. SO is associated with insulin resistance, inappropriate nutrition, and low physical activity.

OBJECTIVE: To determine the degree of disparity in unmet healthcare needs between people with disabilities and the general population in South Korea, and to analyze their perspective reasons. METHOD: Survey results of 9,744 subjects that participated in the 4th Korea National Health and Nutrition Examination Survey and 7,000 people that participated in the 2008 Survey of Disabled people were used in this population-based cross-sectional study. Unmet healthcare needs were identified as reporting experience during the last 12 months when there was a need to see a doctor, but were unable to get it. We assessed unmet healthcare needs by demographic variables, social variables and characteristics of disability. Chi-square test and logistic regression were used to determine which variables were related to unmet healthcare needs. RESULTS: A total of 22.1% of people with disabilities and 22.8% of the general population had unmet healthcare needs. However, brain impairment (25.3%) and physical impairment (25.2%) had more unmet healthcare needs than the general population and other disabilities. Unmet healthcare needs of people with disabilities was related to sex, age, self-perceived health, marital status, income, occupation and category of disability. Whereas the reasons for unmet healthcare needs in people with disabilities were lack of money (57.3%) and inaccessible transportation (12.8%), those for the general population were no available time (30.2%) and mild symptoms (23.8%). CONCLUSION: Brain and physical impairment cases with limitations to accessible transportation had the higher unmet healthcare needs. In addition, the reasons for people with these disabilities were more environmental than those of the general population.
