Background A certain number of patients with coronavirus disease 2019 , particularly those who test positive for SARS-CoV-2 in the serum, are hospitalized. Further, some even die. We examined the effect of blood adsorption therapy using columns that can eliminate SARS-CoV-2 on the improvement of the prognosis of severe COVID-19 patients. Methods This study enrolled seven patients receiving mechanical ventilation. The patients received viral adsorption therapy using SARS-catch column for 3 days. The SARS-catch column was developed by immobilizing a specific peptide, designed based on the sequence of human angiotensin-converting enzyme 2 (hACE2), to an endotoxin adsorption column (PMX). In total, eight types of SARS-CoV-2-catch (SCC) candidate peptides were developed. Then, a clinical study on the effects of blood adsorption therapy using the SARS-catch column in patients with severe COVID-19 was performed, and the data in the present study were compared with historical data of severe COVID-19 patients. Results Among all SCC candidate peptides, SCC-4N had the best adsorption activity against SARS-CoV-2. The SARS-catch column using SCC-4N removed 65% more SARS-CoV-2 than PMX. Compared with historical data, the weaning time from mechanical ventilation was faster in the present study. In addition, the rate of negative blood viral load in the present study was higher than that in the historical data. ConclusionThe timely treatment with virus adsorption therapy may eliminate serum SARS-CoV-2 and improve the prognosis of patients with severe COVID-19. However, large-scale studies must be performed in the future to further assess the finding of this study (jRCTs052200134).

Background Supporting parents with severe and persistent mental illness (SPMI) requires knowledge, skills, and a positive attitude toward parenthood. We developed a Japanese e-learning program for public health nurses (PHNs) to enable them to support parents with SPMI and their family members. This study aimed to evaluate the effectiveness of the program in improving the knowledge, skills, attitudes, and self-efficacy of PHNs in supporting them. Methods A three-hour video-based e-learning program was developed. A randomized controlled trial was conducted with 176 PHNs responsible for maternal and child health in Japan. The outcome measures included the Sense of Coping Difficulty/Possibility Scale, skills to support people with SPMI, and achievement of program goals. Outcome data were collected at three time points during the study: baseline (T1), post-intervention (T2), and one month after T2 (T3) using self-administered electronic questionnaires. Outcome measures were assessed by comparing the two groups at the endpoint (T3) using t-tests and ANOVA. Effectiveness over time was assessed using a mixed model for repeated measures, with group and time interactions as fixed effects. Results The study participants were randomly allocated to two groups:89 in the intervention group, and 87 in the control group. The total score and the scores in the two subscales of the Sense of Coping Difficulty/Possibility Scale in the intervention group at T3 were significantly higher than those in the control group, as shown by the t-test and ANOVA (all p<0.001). The Sense of Coping Difficulty subscale had a large effect size (Cohen’s d=1.27). The analysis of the results of a mixed model for repeated measures showed that the group and time interactions on all outcome measures were not significantly different at T1 but were significantly different at T2 and T3. Conclusions The program was effective one month after its completion, particularly in reducing PHNs’ difficulties in supporting parents with SPMI. Trial registration UMIN000045765, November 1, 2021.

Background Some children of parents with mental illness need support. This study aimed to develop and test the effectiveness of an e-learning program for training elementary schoolteachers to support children of parents with mental illness. Methods The program, which included a 30-min video-based e-learning program, aimed to help schoolteachers gain basic knowledge about mental illness and children of parents with mental illness, recognize children in need of support, and gain confidence in supporting them. A school-based cluster randomized controlled trial was conducted, and the schools were randomly divided into intervention and control groups. The teachers at these schools signed up for the program and participated individually. The outcome measures for the schoolteachers were evaluated at three time points: baseline (T1), post (T2), and one month later (T3). Along with the Sense of Coping Difficulty subscale (primary outcome measure), the following self-developed outcome measures were used: actual behaviors and attitude toward supporting children, knowledge, and self-assessment of program goals achievement. The Sense of Coping Difficulty subscale results at T3 were compared between the groups. Effectiveness over time was assessed for all the outcome measures. The interaction between baseline and intervention effects on the Sense of Coping Difficulty subscale was analyzed. As a part of the process evaluation, open-ended text responses were analyzed qualitatively. Results Baseline responses were collected from 87 participants in the intervention group and 84 in the control group. The total score of the Sense of Coping Difficulty subscale at T3 was significantly lower in the intervention group than in the control group (p = 0.007). Over time, a significant effect was observed on the Sense of Coping Difficulty subscale, actual behavior, knowledge of onset timing and probability of onset, and achievement of all program goals. Exploratory analysis was particularly effective for those who encountered a high level of difficulty in supporting children. The participants’ text responses indicated that they planned to look carefully at children's backgrounds and stay close to them in the future. Conclusions The program was effective for schoolteachers in supporting children of parents with mental illness. Trial registration UMIN000045483; 14/09/2021.
