Objective: The Scales for Outcomes in Parkinson’s Disease–Cognition (SCOPA-Cog) was developed to assess cognition in patients with Parkinson’s disease (PD). In this study, we aimed to evaluate the validity and reliability of the Korean version of the SCOPACog (K-SCOPA-Cog). Methods: We enrolled 129 PD patients with movement disorders from 31 clinics in South Korea. The original version of the SCOPA-Cog was translated into Korean using the translation-retranslation method. The test–retest method with an intraclass correlation coefficient (ICC) and Cronbach’s alpha coefficient were used to assess reliability. Spearman’s rank correlation analysis with the Montreal Cognitive Assessment-Korean version (MOCA-K) and the Korean Mini-Mental State Examination (K-MMSE) were used to assess concurrent validity. Results: The Cronbach’s alpha coefficient was 0.797, and the ICC was 0.887. Spearman’s rank correlation analysis revealed a significant correlation with the K-MMSE and MOCA-K scores (r = 0.546 and r = 0.683, respectively). Conclusion Our results demonstrate that the K-SCOPA-Cog has good reliability and validity.

Purpose: This study aimed to develop standardized guidelines for telephone consultations and assess the impact of computerization on clinical utility. Methods: Guidelines for patient classification were developed for 14 symptoms, validated by experts, and integrated into a real-time computer program. Patient classification involved categorizations of ‘observation,’ ‘outpatient,’ and ‘emergency’.Subsequent to computerization, a survey was conducted to evaluate its usefulness. Results: Items with an Item-Content Validity Index (I-CVI) score of 0.75 or lower were removed or adjusted within the guidelines. Analysis of 200 consultation records indicated that lung cancer (87 cases) was the most common disease and the most prevalent symptom was pain (57 cases). Among 93 cases classified as ‘observation’, 6 patients visited the emergency room. Among 30 cases categorized as ‘outpatient’, 24 patients visited a clinic, and 6 patients visited the emergency room. Of the 19 cases classified as ‘emergency’, 18 patients actually visited the emergency room. User satisfaction from 12 nurses was very high, with an average score of 3.7/4. Conclusion Due to the standardized telephone triage and the concurrent implementation of a computerized program, healthcare professionals can conveniently and comprehensively analyze big data pertaining to patients’ symptoms. Ultimately, nurses were able to receive help with more specialized telenursing.

Viral load and the duration of viral shedding of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are important determinants of the transmission of coronavirus disease 2019.In this study, we examined the effects of viral doses on the lung and spleen of K18-hACE2 transgenic mice by temporal histological and transcriptional analyses. Approximately, 1×105 plaque-forming units (PFU) of SARS-CoV-2 induced strong host responses in the lungs from 2 days post inoculation (dpi) which did not recover until the mice died, whereas responses to the virus were obvious at 5 days, recovering to the basal state by 14 dpi at 1×102 PFU. Further, flow cytometry showed that number of CD8+ T cells continuously increased in 1×102 PFU-virusinfected lungs from 2 dpi, but not in 1×105 PFU-virus-infected lungs. In spleens, responses to the virus were prominent from 2 dpi, and number of B cells was significantly decreased at 1×105PFU; however, 1×102 PFU of virus induced very weak responses from 2 dpi which recovered by 10 dpi. Although the defense responses returned to normal and the mice survived, lung histology showed evidence of fibrosis, suggesting sequelae of SARS-CoV-2 infection. Our findings indicate that specific effectors of the immune response in the lung and spleen were either increased or depleted in response to doses of SARS-CoV-2. This study demonstrated that the response of local and systemic immune effectors to a viral infection varies with viral dose, which either exacerbates the severity of the infection or accelerates its elimination.
