The majority of parasitological studies of terrestrial snakes in Korea have focused on zoonotic parasites. However, in the present study, we describe 3 unrecorded nematode species recovered from 5 species of snakes (n=6) in Korea. The examined snakes, all confiscated from illegal hunters, were donated by the Chungnam Wild Animal Rescue Center and Korean Broadcasting System in July 2014 and February 2015. Light and scanning electron microscopies on the shapes of spicules that are either bent or straight (kalicephalids) and the presence of the intestinal cecum (ophidascarids) figured out 3 nematodes; Kalicephalus brachycephalus Maplestone, 1931, Kalicephalus sinensis Hsü, 1934, and Ophidascaris excavata Hsü and Hoeppli, 1934. These 3 species of nematode faunas are recorded for the first time in Korea.

OBJECTIVES: To see the effect of dietary administration of omega 3-fatty acid formula on the vaginal cells of postmenopausal rats. METHODS: Three-week-old female Wistar/ST rats were raised after one week of adjustment period. The rats were then divided into three groups, for three different kinds of diet; general diet, 1% omega-3 fatty acid diet, and 2% omega-3 fatty acid diet. After eight weeks of having assigned diet, after the oophorectomy, with the same diet previously they had Immunohistochemistry, Immunofluorescence, and Western Blot about ezrin, merlin were done. RESULTS: In immunohistochemistry, estrogen injection group revealed thicker and well differentiated features. In Immunofluorescence, Omega-3 fatty acid composition in diet did not effect expression of ezrin and merlin in rat vagina in estrogen injection group, their vaginal epithelium showed full layers (from basal to apical layer). In Western Blot analysis, Omega-3 fatty acid composition in diet did not affect expression of ezrin and merlin in rat vagina estrogen presented significant impact on expression of ezrin and merlin. CONCLUSION: Although omega-3 fatty acid composition changed in diet, vaginal epithelial morphology unchanged. Estrogen did effect on vagina cell, but omega-3 fatty acid did not effect on ezrin and merlin in vagina.

In July 2014, a nematode species, Schistorophus cirripedesmi Rhizhikov and Khokhlova, 1964, was recovered from a bar-tailed godwit, Limosa lapponica baueri that was stored in a -20˚C freezer in the Chungnam Wild Animal Rescue Center. The bird was collected in 2012 from the coastal region of Pyeongtaek-si (City), Gyeonggi-do (Province) in the Republic of Korea, although the exact date is not clear. At necropsy, 9 nematodes were found in the gizzard of the bird. The parasites had 4 horn-like cephalic cuticular ornamentations. After morphometric comparison and morphological observations, including scanning electron microscopy, the nematodes were identified as S. cirripedesmi. This is the first description of a nematode species in a shorebird in Korea. This is also the first time this genus and species have been found in Korea.

Background:
Given the expanding clinical use of poly(adenosine diphosphate [ADP]-ribose) polymerase inhibitors (PARPis), there is a significant need for optimal strategies with which to treat patients whose cancer progresses while using a PARPi. However, the treatment consensus after PARPi has not been established. The aim of the Korean Gynecologic Oncology Group (KGOG) 3056/NIRVANA-R trial is to investigate the efficacy of niraparib in combination with bevacizumab as a maintenance therapy in platinum-sensitive ovarian cancer patients who were previously treated with a PARPi.
Methods
The KGOG 3056/NIRVANA-R is a multi-centre, investigator-initiated, single-arm, phase II trial of patients with platinum-sensitive recurrent ovarian cancer recruited from seven KGOG sites. This study included patients with platinum-sensitive recurrent epithelial ovarian cancer who received at least 2 previous courses of platinum-containing therapy and had been treated with a PARPi. Mucinous histology type was excluded. Patients who had responded to the last platinum regimen (either complete or partial response) were eligible to participate in this study. Forty-four patients will be recruited. All enrolled patients are treated with niraparib and bevacizumab for maintenance therapy until disease progression, unacceptable toxicity, or withdrawal of patient consent. The primary endpoint of the study is 6-month progression-free survival rate. Accrual is expected to be completed in 2022, followed by presentation of results in 2023.

OBJECTIVES: This study developed an information and communication technology (ICT)-based comprehensive health and social-needs assessment (CHSNA) system based on the International Classification of Functioning, Disability, and Health (ICF) with the aim of enhancing person-centered community care for community residents and supporting healthcare professionals and social workers who provide healthcare and social services in the community. METHODS: Items related to a CHSNA tool were developed and mapped with ICF codes. Experts validated the CHSNA system design and process using the Delphi method, and a pilot test of the initial version of the system was conducted. RESULTS: The following three steps of CHSNA were embedded in the system, which had a user-friendly screen and images: basic health assessment, life and activity assessment, and in-depth health assessment. The assessment results for the community residents were presented with visualized health profiles, including images, graphs, and an ICF model. CONCLUSIONS: The developed CHSNA system can be used by healthcare professionals, social workers, and community residents to evaluate the reasoning underlying health and social needs, to facilitate the identification of more appropriate healthcare plans, and to guide community residents to receive the best healthcare services. A CHSNA system can improve the implementation of standardized terminology utilizing the ICF and the accuracy of needs assessments of community residents.

Background:
The preventable trauma death rate survey is a basic tool for the quality management of trauma treatment because it is a method that can intuitively evaluate the level of national trauma treatment. We conducted this study as a national biennial follow-up survey project and report the results of the review of the 2019 trauma death data in Korea.
Methods:
From January 1, 2019 to December 31, 2019, of a total of 8,482 trauma deaths throughout the country, 1,692 were sampled from 279 emergency medical institutions in Korea. All cases were evaluated for preventability of death and opportunities for improvement using a multidisciplinary panel review approach.
Results:
The preventable trauma death rate was estimated to be 15.7%. Of these, 3.1% were judged definitive preventable deaths, and 12.7% were potentially preventable deaths. The odds ratio for preventable traumatic death was 2.56 times higher in transferred patients compared to that of patients who visited the final hospital directly. The group that died 1 hour after the accident had a statistically significantly higher probability of preventable death than that of the group that died within 1 hour after the accident.
Conclusion
The preventable trauma death rate for trauma deaths in 2019 was 15.7%, which was 4.2%p lower than that in 2017. To improve the quality of trauma treatment, the transfer of severe trauma patients to trauma centers should be more focused.
