A Conversation Analysis Study of Speaking Rate Control by a Dysarthric Patient : A Case in which Dysarthria Improved in Conversation Continuity and Length of Utterances through Using a Pacing Board

ペーシングボードの使用により発話明瞭度が向上したdysarthria例に対して,会話分析の立場から「会話の伝達率」と「1発話の長さ」を検討し,主に以下の結果を得た.(1)ペーシングボード非使用時の会話伝達率は54.0%であったのに比し,使用時では98.1%と向上していた.(2)1発話の長さに関しては,モーラ数による比較ではペーシングボード非使用時の平均モーラ数は5.9,使用時は11.9であった.また平均文節数は非使用時1.4,使用時2.8と両指標とも約2倍に延長していた.以上の結果に基づいて,dysarthriaにおける発話速度調節訓練について会話分析から検討を加えた.Conversational transmissibility and length of utterances were studied in a　dysarthric patient who improved in intelligibility　because of use of a pacing board.The following results were obtained : (1)Conversational transmissibility was 54% when the pacing board was not used, whereas　transmissibility improved to 98.1 % when the board was used. (2) Comparison of the utterance length was made based on the number of mora, in which the average mora was 5.9 without use of the pacing board and 11.9 with use of the board. The number of average segments was 1.4 without　the board as opposed to 2.8 with the board. In both cases the indices increased by　nearly twofold when the pacing board was used. Based on these results, discussion　was held on the training of speaking rate control by the dysarthric speaker based on　conversation analysis

Monocyte or white blood cell counts and β₂ microglobulin predict the durable efficacy of daratumumab with lenalidomide

BACKGROUND: Daratumumab is one of the most widely used treatments for relapsed/refractory multiple myeloma (MM) patients. However, not all patients achieve a lasting therapeutic response with daratumumab. OBJECTIVES: We hypothesized that a durable response to daratumumab could be predicted by the balance between the MM tumor burden and host immune status. DESIGN: We conducted a retrospective study using the real-world data in the Kansai Myeloma Forum (KMF) database. METHODS: We retrospectively analyzed 324 relapsed/refractory MM patients who were treated with daratumumab in the KMF database. RESULTS: In this study, 196 patients were treated with daratumumab, lenalidomide, and dexamethasone (DLd) regimen and 128 patients were treated with daratumumab, bortezomib, and dexamethasone (DBd) regimen. The median age at treatment, number of prior treatment regimens and time-to-next-treatment (TTNT) were 68, 4 and 8.02 months, respectively. A multivariate analysis showed that the TTNT under the DLd regimen was longer with either higher monocyte counts (analysis 1), higher white blood cell (WBC) counts (analysis 2), lower β2 microglobulin (B2MG < 5.5 mg/L) or fewer prior regimens (<4). No parameters were correlated with TTNT under the DBd regimen. CONCLUSION: We propose a simple scoring model to predict a durable effect of the DLd regimen by classifying patients into three categories based on either monocyte counts (0 points for ⩾200/μl; 1 point for <200/μl) or WBC counts (0 points for ⩾3500/μl; 1 point for <3500/μl) plus B2MG (0 points for <5.5 mg/L; 1 point for ⩾5.5 mg/L). Patients with a score of 0 showed significantly longer TTNT and significantly better survival compared to those with a score of 1 or 2 (both p < 0.001). To confirm this concept, our results will need to be validated in other cohorts

Prevention of hypoglycemia by intermittent-scanning continuous glucose monitoring device combined with structured education in patients with type 1 diabetes mellitus : A randomized, crossover trial

Aims: We conducted a randomized, crossover trial to compare intermittent-scanning continuous glucose monitoring (isCGM) device with structured education (Intervention) to self-monitoring of blood glucose (SMBG) (Control) in the reduction of time below range. Methods: This crossover trial involved 104 adults with type 1 diabetes mellitus (T1DM) using multiple daily injections. Participants were randomly allocated to either sequence Intervention/Control or sequence Control/Intervention. During the Intervention period which lasted 84 days, participants used the first-generation FreeStyle Libre (Abbott Diabetes Care, Alameda, CA, USA) and received structured education on how to prevent hypoglycemia based on the trend arrow and by frequent sensor scanning (≥10 times a day). Confirmatory SMBG was conducted before dosing insulin. The Control period lasted 84 days. The primary endpoint was the decrease in the time below range (TBR; <70 mg/dL). Results: The time below range was significantly reduced in the Intervention arm compared to the Control arm (2.42 ± 1.68 h/day [10.1 %±7.0 %] vs 3.10 ± 2.28 h/day [12.9 %±9.5 %], P = 0.012). The ratio of high-risk participants with low blood glucose index >5 was significantly reduced (8.6 % vs 23.7 %, P < 0.001). Conclusions: The use of isCGM combined with structured education significantly reduced the time below range in patients with T1DM

The Helicobacter pylori Genome Project : insights into H. pylori population structure from analysis of a worldwide collection of complete genomes

Helicobacter pylori, a dominant member of the gastric microbiota, shares co-evolutionary history with humans. This has led to the development of genetically distinct H. pylori subpopulations associated with the geographic origin of the host and with differential gastric disease risk. Here, we provide insights into H. pylori population structure as a part of the Helicobacter pylori Genome Project (HpGP), a multi-disciplinary initiative aimed at elucidating H. pylori pathogenesis and identifying new therapeutic targets. We collected 1011 well-characterized clinical strains from 50 countries and generated high-quality genome sequences. We analysed core genome diversity and population structure of the HpGP dataset and 255 worldwide reference genomes to outline the ancestral contribution to Eurasian, African, and American populations. We found evidence of substantial contribution of population hpNorthAsia and subpopulation hspUral in Northern European H. pylori. The genomes of H. pylori isolated from northern and southern Indigenous Americans differed in that bacteria isolated in northern Indigenous communities were more similar to North Asian H. pylori while the southern had higher relatedness to hpEastAsia. Notably, we also found a highly clonal yet geographically dispersed North American subpopulation, which is negative for the cag pathogenicity island, and present in 7% of sequenced US genomes. We expect the HpGP dataset and the corresponding strains to become a major asset for H. pylori genomics
