RESUMEN
The infection status of zoonotic trematode metacercariae (ZTM) was investigated in total 568 freshwater fishes (19 species) from the irrigation canal of Togyo-jeosuji (Reservoir) in Cheorwon-gun, Gangwon-do, the Republic of Korea for 3 years (2018-2020). All fishes were examined using the artificial digestion method. The metacercariae of Clonorchis sinensis (CsMc) were detected in 180 (43.8%) out of 411 fish of positive species, and their infection intensity was 38 per fish infected (PFI). Especially, in 2 fish species, i.e., Pseudorasbora parva and Puntungia herzi, the prevalence was 82.1% and 31.3%, and the infection intensity with CsMc was 88 and 290 PFI, respectively. Metagonimus spp. metacercariae (MsMc) were found in 403 (74.1%) out of 544 fish of positive species, and their infection intensity was 62 PFI. In the pale chub, Zacco platypus, the prevalence of MsMc was 98.6%, and their infection intensity was 144 PFI. Centrocestus armatus metacercariae were detected in 171 (38.9%) out of 440 fish of positive species, and their infection intensity was 1,844 PFI. Echinostoma spp. metacercariae were found in 94 (19.6%) out of 479 fish of positive species, and their infection intensity was 3 PFI. Metorchis orientalis metacercariae were detected in 43 (29.3%) out of 147 fish of positive species, and their infection intensity was 4 PFI. By the present study, it has been confirmed that some species of ZTM, including CsMc and MsMc, are prevalent in fishes from the irrigation canal of Togyo-jeosuji in Cheorwon-gun, Gangwon-do, Korea.

RESUMEN
OBJECTIVES: Many patients diagnosed with cancer suffer from various psychiatric symptoms such as depression, anxiety and insomnia as well as cancer itself. Patients with cancer are more vulnerable to possible adverse events of psychotropic medications. Although antidepressants are widely used among cancer patients, there is little information about tolerability of antidepressants. This study was conducted to compare tolerability of antidepressants in cancer patients referred for psychiatric consultation. METHODS: The participants were cancer patients who had been referred to psychiatrist for their psychiatric symptoms. We retrospectively analyzed the data of patients diagnosed with cancer from 9 general hospitals in Korea. The discontinuation rate for a 6 months period after treatment initiation for three antidepressants(Escitalopram, Mirtazapine, Paroxetine) were compared. RESULTS: Antidepressants were prescribed for 96.3% of subjects and Escitalopram 150(47.2%), Mirtazapine 92 (28.9%) and Paroxetine 76(23.9%) were prescribed frequently in order There were no significant differences in discontinuation rates among the three antidepressants during the 6 month period after initiation of pharmacotherapy. But there was a difference in discontinuation rates between inpatients versus outpatients(p<0.0001). CONCLUSIONS: In a naturalistic setting for the antidepressant treatment for cancer patients, it seems that there are no differences in discontinuation rates among these three antidepressants. It is therefore essential that such interactions are carefully considered when treating patients of antidepressants who already have cancer.
