CAUSES OF FUNCTIONAL DECLINE IN ELDERLY HOSPITALIZED PATIENTS RECEIVING EITHER INDIVIDUAL OR EXCLUSIVE REHABILITATION THERAPY: A COHORT STUDY

Background: Recently, exclusive rehabilitation therapy was introduced to prevent functional decline due to hospital-associated deconditioning by managing older inpatients’ activities of daily living in Japan. However, this type of therapy does not provide one-on-one exercises similar to individual rehabilitation therapy. This study aimed to report the present ward conditions and the causes of the functional decline in elderly patients receiving individual or exclusive rehabilitation therapy. Methods: A total of 1,636 inpatients, aged 65 years or older, were included in the study. Barthel Index at admission and discharge was assessed prospectively to analyze functional decline. We further analyzed the causes of functional decline by investigating the inpatient’s medical records. Results: Forty-three inpatients (2.6%) had functional decline during hospitalization. There were no significant differences in age, Barthel Index at the time of admission, and the type of clinical department between inpatients with and without functional decline. The functional decline rate in individual rehabilitation therapy was 8.2%, which was significantly higher compared to exclusive rehabilitation therapy (0.8%). The most common causes of functional decline were a pain, low postoperative physical fitness, malignant neoplasm, and new-onset cerebral stroke. Conclusion: We report the present ward conditions in elderly patients receiving either individual or exclusive rehabilitation therapies. Functional decline was correlated to the inpatients’ disease and conditions. The causes of the functional decline can be classified based on whether rehabilitation was effective or ineffective. If the functional decline was caused by hospital-associated deconditioning, we should address the functional decline by providing appropriate rehabilitation methods

トシキンコウ ニ オケル ノウカレストラン ノ セイコウヨウイン ト ハッテンカノウセイ ─ノウカレストラン イブキ ヲ ジレイ トシテ─

農業に関連した所得の向上や地域の雇用創出につながる取り組みの1つに農家レストランがある。農家レストランは，地元農産物を使用した料理の提供などにより，消費者に農業を身近に感じてもらえる場である一方，高い運営ノウハウが求められる。本稿では，農村部ではなく都市近郊に立地する農家レストランの事例分析から，その成功要因と今後の課題を析出し，都市近郊の農家レストランの長期的な経営維持に必要な要素および発展可能性に対する提言を行った。本事例の成功要因としては，第一に料理や店内の雰囲気，農業関連イベント等の様々な点で競合に打ち勝つための「独自性」を構築していること，第二に経営者が従業員と経営理念や経験を共有し，店全体としてモチベーションを維持させていることが挙げられる。また，農村部と都市近郊の農家レストランの外部環境の違いから，都市近郊の農家レストランの長期的な経営維持には，多面的機能の発揮による生産者・消費者との信頼関係の醸成が必要であると指摘した。加えて，都市近郊の農家レストランの発展には農家レストランを核としたコミュニティの存在が重要であると結論づけた。Farm restaurants are part of the efforts to raise agricultural income and create local employment. These restaurants prepare dishes using local agricultural products, making consumers more appreciative of agriculture. However, operating farm restaurants requires high managerial know-how. This study identifies the success factors and prospective challenges by analyzing the case of a farm restaurant located in a suburban instead of rural area. Further, it discusses the factors and potentialities necessary for its long-term development. The success factors derived from the case are as follows : 1) creating authenticity to survive competition in various aspects such as quality of food prepared, ambience, and agricultural-related events and 2) sustaining overall motivation by sharing management philosophy and experience with employees. The study also highlights that it is necessary for the sustainable management of farm restaurants in the suburbs to build mutual trust with local producers and consumers by fulfilling their multiple functions. The study concludes that it is important for the development of suburban farm restaurants to have communities dedicated to farm restaurants

On the origin and evolution of the asteroid Ryugu: A comprehensive geochemical perspective

Presented here are the observations and interpretations from a comprehensive analysis of 16 representative particles returned from the C-type asteroid Ryugu by the Hayabusa2 mission. On average Ryugu particles consist of 50% phyllosilicate matrix, 41% porosity and 9% minor phases, including organic matter. The abundances of 70 elements from the particles are in close agreement with those of CI chondrites. Bulk Ryugu particles show higher δ18O, Δ17O, and ε54Cr values than CI chondrites. As such, Ryugu sampled the most primitive and least-thermally processed protosolar nebula reservoirs. Such a finding is consistent with multi-scale H-C-N isotopic compositions that are compatible with an origin for Ryugu organic matter within both the protosolar nebula and the interstellar medium. The analytical data obtained here, suggests that complex soluble organic matter formed during aqueous alteration on the Ryugu progenitor planetesimal (several 10’s of km), <2.6 Myr after CAI formation. Subsequently, the Ryugu progenitor planetesimal was fragmented and evolved into the current asteroid Ryugu through sublimation

The whole blood transcriptional regulation landscape in 465 COVID-19 infected samples from Japan COVID-19 Task Force

「コロナ制圧タスクフォース」COVID-19患者由来の血液細胞における遺伝子発現の網羅的解析 --重症度に応じた遺伝子発現の変化には、ヒトゲノム配列の個人差が影響する--. 京都大学プレスリリース. 2022-08-23.Coronavirus disease 2019 (COVID-19) is a recently-emerged infectious disease that has caused millions of deaths, where comprehensive understanding of disease mechanisms is still unestablished. In particular, studies of gene expression dynamics and regulation landscape in COVID-19 infected individuals are limited. Here, we report on a thorough analysis of whole blood RNA-seq data from 465 genotyped samples from the Japan COVID-19 Task Force, including 359 severe and 106 non-severe COVID-19 cases. We discover 1169 putative causal expression quantitative trait loci (eQTLs) including 34 possible colocalizations with biobank fine-mapping results of hematopoietic traits in a Japanese population, 1549 putative causal splice QTLs (sQTLs; e.g. two independent sQTLs at TOR1AIP1), as well as biologically interpretable trans-eQTL examples (e.g., REST and STING1), all fine-mapped at single variant resolution. We perform differential gene expression analysis to elucidate 198 genes with increased expression in severe COVID-19 cases and enriched for innate immune-related functions. Finally, we evaluate the limited but non-zero effect of COVID-19 phenotype on eQTL discovery, and highlight the presence of COVID-19 severity-interaction eQTLs (ieQTLs; e.g., CLEC4C and MYBL2). Our study provides a comprehensive catalog of whole blood regulatory variants in Japanese, as well as a reference for transcriptional landscapes in response to COVID-19 infection

DOCK2 is involved in the host genetics and biology of severe COVID-19

「コロナ制圧タスクフォース」COVID-19疾患感受性遺伝子DOCK2の重症化機序を解明 --アジア最大のバイオレポジトリーでCOVID-19の治療標的を発見--. 京都大学プレスリリース. 2022-08-10.Identifying the host genetic factors underlying severe COVID-19 is an emerging challenge. Here we conducted a genome-wide association study (GWAS) involving 2, 393 cases of COVID-19 in a cohort of Japanese individuals collected during the initial waves of the pandemic, with 3, 289 unaffected controls. We identified a variant on chromosome 5 at 5q35 (rs60200309-A), close to the dedicator of cytokinesis 2 gene (DOCK2), which was associated with severe COVID-19 in patients less than 65 years of age. This risk allele was prevalent in East Asian individuals but rare in Europeans, highlighting the value of genome-wide association studies in non-European populations. RNA-sequencing analysis of 473 bulk peripheral blood samples identified decreased expression of DOCK2 associated with the risk allele in these younger patients. DOCK2 expression was suppressed in patients with severe cases of COVID-19. Single-cell RNA-sequencing analysis (n = 61 individuals) identified cell-type-specific downregulation of DOCK2 and a COVID-19-specific decreasing effect of the risk allele on DOCK2 expression in non-classical monocytes. Immunohistochemistry of lung specimens from patients with severe COVID-19 pneumonia showed suppressed DOCK2 expression. Moreover, inhibition of DOCK2 function with CPYPP increased the severity of pneumonia in a Syrian hamster model of SARS-CoV-2 infection, characterized by weight loss, lung oedema, enhanced viral loads, impaired macrophage recruitment and dysregulated type I interferon responses. We conclude that DOCK2 has an important role in the host immune response to SARS-CoV-2 infection and the development of severe COVID-19, and could be further explored as a potential biomarker and/or therapeutic target

Ultralight vector dark matter search using data from the KAGRA O3GK run

Among the various candidates for dark matter (DM), ultralight vector DM can be probed by laser interferometric gravitational wave detectors through the measurement of oscillating length changes in the arm cavities. In this context, KAGRA has a unique feature due to differing compositions of its mirrors, enhancing the signal of vector DM in the length change in the auxiliary channels. Here we present the result of a search for U(1)B−L gauge boson DM using the KAGRA data from auxiliary length channels during the first joint observation run together with GEO600. By applying our search pipeline, which takes into account the stochastic nature of ultralight DM, upper bounds on the coupling strength between the U(1)B−L gauge boson and ordinary matter are obtained for a range of DM masses. While our constraints are less stringent than those derived from previous experiments, this study demonstrates the applicability of our method to the lower-mass vector DM search, which is made difficult in this measurement by the short observation time compared to the auto-correlation time scale of DM

MALDI-Based Mass Spectrometry in Clinical Testing: Focus on Bacterial Identification

The term “proteome” refers to the total of all proteins expressed in an organism. The term “proteomics” refers to the field of research that includes not only information on the expression levels of individual proteins, but also their higher-order structures, intermolecular interactions, and post-translational modifications. The core technology, matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS), is available for protein analysis thanks to the work of Koichi Tanaka and John Fenn, who were awarded the Nobel Prize in Chemistry in 2002. The most successful proteome analysis in clinical practice is rapid microbial identification. This method determines the bacterial species by comparing the proteome profile of the bacteria obtained by matrix-assisted laser desorption ionization-time of flight MS (MALDI-TOF MS) with a database. MS is superior in simplicity, speed, and accuracy to classic speciation by staining and phenotyping. In clinical microbiology, MS has had a large impact on the diagnosis and treatment of infectious disease. Early diagnosis and treatment of infectious disease are important, and rapid identification by MALDI-TOF MS has made a major contribution to this field
