In 2020, the COVID-19 pandemic has had unprecedented impacts on various aspects of the world. Each academic society has published a guide and/or guidelines on how to cope with COVID-19 separately. As the one and only nationwide association of academic societies that represent medical science in Japan, JMSF has decided to publish the expert opinion to help patients and care providers find specifically what they want.This expert opinion is a summary of recommendations by many academic societies and will be updated when necessary. Patients that each academic society targets differ even though they suffer from the same COVID-19, and recommendations can be different in a context-dependent manner. Readers are supposed to be flexible and adjustable when they use this expert opinion.

Objectives: This study investigated the effect of early mobilization [EM; physical rehabilitation with the intensity needed to sit on the edge of the bed started within 5 days of intensive care unit (ICU) admission] in relation to improvements in gait independence and other clinical outcomes.Methods: This retrospective single-center study evaluated patients aged at least 18 years who stayed in the ICU for at least 48 h and were categorized into EM and late mobilization (LM; physical rehabilitation started more than 5 days after ICU admission) groups. Outcomes were compared after adjusting for 20 background factors by propensity score matching and inverse probability of treatment weighting. The primary outcome was independent gait at discharge. The secondary outcomes were medical costs, 90-day survival, and durations of ICU and hospital stays.Results: Of 177 patients, 85 and 92 were enrolled in the EM and LM groups, respectively. Propensity score matching created 37 patient pairs. There was no significant difference in the 90-day survival rate (P=0.308) or medical costs (P=0.054), whereas independent gait at discharge (P=0.025) and duration of hospital stay (P=0.013) differed significantly. Multivariate logistic regression analysis showed that EM was independently associated with independent gait at discharge (P=0.011) and duration of hospital stay (P=0.010) but was not associated with 90-day survival (odds ratio: 2.64, 95% confidence interval: 0.67–13.12, P=0.169).Conclusions: Early mobilization in the ICU did not affect 90-day survival and did not lower medical costs but was associated with independent gait at discharge and shorter hospital stays.

DNA methylation in higher organisms has become an expanding field of study as it often involves the regulation of gene expression. Although Whole Genome Bisulfite Sequencing (WG-BS) based on next-generation sequencing (NGS) is the most versatile method, this is a costly technique that lacks in-depth analytic power. There are no conventional methods based on NGS that enable researchers to easily compare the level of DNA methylation from the practical number of samples handled in the laboratory. Although the targeted BS method based on Sanger sequencing is generally used in this case, it lacks in-depth analytic power. Therefore, we propose a new method that combines the high throughput analytic power of NGS and bioinformatics with the specificity and focus offered by PCR-amplification-based bisulfite sequencing methods. We use in silico size sieving of DNA-fragments and primer matchings instead of whole-fragment alignment in our bioinformatics analyses, and named our method SIMON (Simple Inference for Methylome based On NGS). The results of our targeted BS method based on NGS (SIMON method) show that small variations in DNA methylation patterns can be precisely and efficiently measured at a single nucleotide resolution. SIMON method combines pre-existing techniques to provide a cost-effective technique for in-depth studies that focus on pre-identified loci. It offers significant improvements with regard to workflow and the quality of the acquired DNA methylation information. Because of the high accuracy of the analysis, small variations of DNA methylation levels can be precisely determined even with large numbers of samples and loci.

Salicylic acid (SA) is known to be involved in the immunity against Clavibacter michiganensis ssp. michiganensis (Cmm) that causes bacterial canker in tomato. To identify the candidate genes associated with SA-inducible Cmm resistance, transcriptome analysis was conducted via RNA sequencing in tomato plants treated with SA. SA treatment upregulated various defense-associated genes, such as PR and GST genes, in tomato cotyledons. A comparison of SA- and Cmm-responsive genes revealed that both SA treatment and Cmm infection commonly upregulated a large number of genes. Gene Ontology (GO) analysis indicated that the GO terms associated with plant immunity were over-represented in both SA- and Cmm-induced genes. The genes commonly downregulated by both SA treatment and Cmm infection were associated with the cell cycle and may be involved in growth and immunity trade-off through cell division. After SA treatment, several proteins that were predicted to play a role in immune signaling, such as resistance gene analogs, Ca2+ sensors, and WRKY transcription factors, were transcriptionally upregulated. The W-box element, which was targeted by WRKYs, was over-represented in the promoter regions of genes upregulated by both SA treatment and Cmm infection, supporting the speculation that WRKYs are important for the SA-mediated immunity against Cmm. Prediction of protein–protein interactions suggested that genes encoding receptor-like kinases and EF-hand proteins play an important role in immune signaling. Thus, various candidate genes involved in SA-inducible Cmm resistance were identified.

Objective Acute-onset diffuse interstitial lung disease (AoDILD) in patients with rheumatoid arthritis (RA) has been a serious concern, especially for those under treatment with biological agents which may affect the presentation and outcome of AoDILD, including Pneumocystis pneumonia (PCP). Therefore, we conducted a retrospective, multi-center study of AoDILD in RA patients receiving biological agents. Methods Patients who developed AoDILD while receiving biological agents (infliximab, etanercept, adalimumab and tocilizumab) were enrolled in the study. Definite PCP was defined as patients who showed either P. jirovecii organisms in their respiratory samples by microscopic examination, or positive tests for both P. jirovicii DNA-PCR with respiratory samples and an elevated serum 1,3-β-D-glucan level above the cut-off value. Probable PCP was defined as either a positive test for P. jirovicii PCR or an elevated serum β-D-glucan level. Chest HRCT findings were evaluated and scored by two board-certified radiologists. Results The final diagnoses for 26 patients examined were definite PCP for 13 patients, probable PCP for 11, and methotrexate-associated pneumonitis in 2 patients. Definite and probable PCP cases were clinically indistinguishable. Generalized, diffuse ground-glass opacity (GGO) is the characteristic HRCT finding in patients with definite or probable PCP, which was different from our previous findings in RA patients, mostly without biologics, showing GGO distributed in a panlobular or multilobular manner. The clinical outcome was favorable by treatment with trimethoprim-sulfamethoxazole and glucocorticoids. Conclusion The possibility of PCP should be intensively investigated in RA patients developing AoDILD while receiving biological agents.
