In this way, more typical human brain behaviors could be simulated, including the effect of age on latency and error generation, cerebellar infarct, trauma and memory loss pharmacological actions (such as those caused by hyoscines and nitrazepam). Conclusion Thus, this study developed a new approach for implementing the manner in which the brain works in semiconductor devices for improving medical research. © 2020 Dai et al.Purpose Chronic obstructive pulmonary disease (COPD) is associated with increased incidence of arrhythmias, which has been attributed to autonomic dysregulation. Detection of autonomic function may facilitate stratification of COPD patients with respect to their risk of development of arrhythmias. Patients and Methods A total of 151 COPD patients and 45 non-COPD patients were included in this study. Heart rate deceleration runs (DRs) were detected by dynamic electrocardiogram (ECG); DRs successively occurring in 2, 4, or 8 cardiac cycles were denoted as DR2, DR4, and DR8, respectively. Indicators of arrhythmias including isolated premature atrial contractions (PAC), supraventricular tachycardia (SVT), isolated premature ventricular contractions (PVC), and ventricular tachycardia (VT) were recorded. Occurrence of SVT or PAC ≥70/day was considered positive for supraventricular arrhythmias, while positive ventricular arrhythmias category (PVAC) was defined as occurrence of VT or PVC ≥10/hour. Results Compared with non-COPD individuals, COPD patients were associated with increased number of PAC, PVC, higher incidence of PAC >70/d, SVT, PVAC, and decreased DRs (DR2, DR4, DR8) (PDR2 for PVAC. check details Conclusion Our study provides evidence of significant autonomic dysregulation in COPD patients. DRs may serve as a marker of the risk of arrhythmias in COPD patients. © 2020 Kong et al.Rationale Current guidelines recommend that patients hospitalized for acute exacerbations of chronic obstructive pulmonary disease (COPD) initiate pulmonary rehabilitation (PR) shortly after discharge from the hospital. However, fewer than 2 percent of Medicare beneficiaries do so. Few studies have examined hospitalized patients' perceptions of the barriers and facilitators to enroll in PR. The aim of this study was to develop an understanding of these factors by interviewing patients. Methods We conducted semi-structured interviews with patients during a hospitalization for COPD exacerbation in a large teaching hospital. Directed content analysis was used to code and analyze interview transcripts. Results Of the 15 patients we interviewed, 9 had participated in PR prior to their hospitalization, 10 were women; 4 were black, and 1 was Hispanic. Facilitators of enrollment included a desire to learn more about the disease, social support, and trust in the health-care provider recommending PR. Barriers to enrollment included lack of awareness, family obligations, lack of motivation, and transportation. For those who had previous experience with PR, but who did not complete the program, another barrier was not feeling well enough. Facilitators to adherence included the educational component of the program; feeling better through exercise; and a social connection with both participants and staff. For some patients. PR contributed to a renewed sense of hope or meaning. Most interviewees expressed interest in a peer coaching program. Conclusion Our results highlight the importance of increasing awareness of PR and building trust between the provider and patients to facilitate initial enrollment. Future interventions to improve enrollment and adherence should address the need for education about the benefits of PR and the value of social support. © 2020 Spitzer et al.Introduction Older listeners have difficulty understanding speech in unfavorable listening conditions. To compensate for acoustic degradation, cognitive processing skills, such as working memory, need to be engaged. Despite prior findings on the association between working memory and speech recognition in various listening conditions, it is not yet clear whether the modality of stimuli presentation for working memory tasks should be auditory or visual. Given the modality-specific characteristics of working memory, we hypothesized that auditory working memory capacity could predict speech recognition performance in adverse listening conditions for older listeners and that the contribution of auditory working memory to speech recognition would depend on the task and listening condition. Methods Seventy-six older listeners and twenty younger listeners completed four kinds of auditory working memory tasks, including digit and speech span tasks, and sentence recognition tasks in four different listening conditionshe modality-specific characteristics of working memory into account may be a key to better understand the difficulty in speech recognition in daily listening conditions for older listeners. © 2020 Kim et al.Biosimilars of granulocyte colony-stimulating factor (G-CSF) have been routinely introduced into clinical practice. However, not functional genomics characterization has been performed yet in comparison with the innovator G-CSF. This study aimed to evaluate the transcriptomic changes in an in vitro model of umbilical cord blood cells (UBC) exposed to G-CSF for the identification of their modulated pathways. Umbilical cord blood cells-derived mononuclear cells (MNCs) were treated with biosimilar and innovator G-CSF for further gene expression profiling analysis using a microarray-based platform. Comparative analysis of biosimilar and innovator G-CSF gene expression signatures allowed us to identify the most commonly modulated pathways by both drugs. In brief, we observed predominantly upmodulation of transcripts related to PI3K-Akt, NF-kappaB, and tumor necrosis factor (TNF) signaling pathways as well as transcripts related to negative regulation of apoptotic process among others. In addition, hematopoietic colony-forming cell assays corroborate the G-CSF phenotypic effects over UBC-derived MNCs. In conclusion, our study suggests that G-CSF impacts UBC-derived cells through the modulation of several signaling pathways associated with cell survival, migration, and proliferation. The concordance observed between biosimilar and innovator G-CSF emphasizes their similarity in regards to their specificity and biological responses. © The Author(s) 2020.
