PURPOSE: Hybrid therapy with catheter ablation of the cavo-tricuspid isthmus (CTI) and continuation of anti-arrhythmic drugs (AAD), or electrical cardioversion with AADs might be alternative treatments for patients with persistent atrial fibrillation (AF). The goal of study was to assess the long term success rate of hybrid therapy for persistent AF compared to antiarrhythmic medication therapy after electrical cardioversion and identify the independent risk factors associated with recurrence after hybrid therapy. MATERIALS AND METHODS: A total of 32 patients with persistent AF who developed atrial flutter after the administration of a class Ic or III anti-arrhythmic drug were enrolled. This group was compared with a group (33 patients) who underwent cardioversion and received direct current cardioversion with AADs. Baseline data were collected, and electrocardiogram and symptom driven Holter monitoring were performed every 2-4 months. RESULTS: There was no significant difference in the baseline characteristics between the groups. The 12 month atrial arrhythmia free survival was better in the hybrid group, 49.0% vs. 33.1%, p=0.048. However, during a mean 55.7+/-43.0 months of follow up, the improved survival rate regressed (p=0.25). A larger left atrium size was an independent risk factor for the recurrence of AF after adjusting for confounding factors. CONCLUSION: Despite favorable outcome during 12 month, the CTI block with AADs showed outcomes similar to AAD therapy after electrical cardioversion over a 12 month follow up period. Minimal substrate modification with AADs might be an alternative treatment for persistent AF with minimal atrial remodeling.

Caring for people with dementia is associated with multiple devastating social, financial, physical, and psychological challenges. There is strong evidence that multicomponent tailored caregiver intervention is effective in improving caregiver well-being and delaying institutionalization. In US, the government is actively funding for developing caregiver program and to prove its efficacy through randomized controlled trials (RCTs) to translate into practice. Even with the introduction of Korean Long-term Care Plan, still, the most of the patients with dementia are being cared by the family members. The distress of caregiving is enormous, but structured therapeutic intervention program which efficacy is proven through RCT is very insufficient in Korea. The purpose of this article is to review the caregiver intervention programs of ongoing clinical trials comparing US and Korea, and to propose a tailored, therapeutic intervention program (I-CARE; A multicenter, randomized trial to assess efficacy of therapeutic intervention programs for decreasing caregiver burden in dementia caregiver) for hospital-care in Korea.

Background: Snakebites remain a devastating and life-threatening environmental hazard.While the management of snakebites has been well described in humans, few clinical data and guidelines exist for dogs, especially in Korea. Objectives: This retrospective study evaluated the clinical features of 70 dogs with snakebite wounds in Korea. Methods: The medical records of 72 dogs that presented to three animal hospitals from June 2008 to July 2021 were reviewed; among these, 70 dogs that met the inclusion criteria were enrolled. Their signalment, history, clinical signs, physical examination, blood analysis, treatment, and prognosis were also evaluated. Results: Of 70 dog owners, 35 (50%) witnessed the bite, with a mean time between bite and hospital presentation of 9.7 ± 4.1 h in 58 dogs. Blood smears were evaluated in 45 dogs, of which 28 (62%) showed echinocytosis. Anemia and acute kidney injury were found in 21 (29%) and 2 dogs (3%), respectively. A total of 37 dogs (53%) were hospitalized, 5 (7%) of which died. Conclusions The most significant finding was the high prevalence of echinocytosis. The data from this retrospective study could inform the management of dogs bitten by snakes in Korea.
