Abstract
The aim of this study is to evaluate the survival benefit of consolidative autologous hematopoietic stem cell transplantation (ASCT) in patients with peripheral T-cell lymphomas (PTCL). In this retrospective study, the ASCT group underwent consolidative ASCT after first-line therapy at 14 transplantation centers in China between January 2001 and December 2019. Data were collected over the same time frame for the non-ASCT group from the database of lymphoma patient records at Peking University Cancer Hospital & Institute. A total of 120 and 317 patients were enrolled in the ASCT and non-ASCT groups, respectively, and their median ages were 43 years and 51 years, respectively. In the ASCT group, 101 patients had achieved complete remission (CR) and 19 patients had achieved partial remission at the time of ASCT. The median follow-up time was 40.2 months and 68 months, and the 3-year overall survival (OS) rate was 80.6% and 48.9% (p < 0.001) for the ASCT and non-ASCT groups, respectively. The beneficial effect of ASCT for OS remained even after propensity score-matched (PSM) analysis (81.6% vs 68.3%, p = 0.001). Among the 203 patients who were aged ≤ 65 years and achieved CR, ASCT conferred a significant survival benefit (3-year progression-free survival [PFS]: 67.4% vs 47.0%, p = 0.004; 3-year OS: 84.0% vs 74.1%, p = 0.010), and this was also maintained after PSM analysis (3-year PFS: 66.6% vs 48.4%, p = 0.042; 3-year OS: 84.8% vs 70.5%, p = 0.011). Consolidative ASCT improved the survival outcome of PTCL patients, even those who achieved CR after first-line therapy.

Abstract
To be time and resource efficient in neonatal research and to answer clinically relevant questions with validity and generalizability, large numbers of infants from multiple hospitals need to be included. Multijurisdictional research in Canada is currently fraught with research ethics review process hurdles that lead to delays, administrative costs, and possibly termination of projects. We describe our experience applying for ethics review to 13 sites in 7 provinces for a project comparing two standard of care therapies for preterm born infants with respiratory distress syndrome. We welcome the current opportunity created by the Institute of Human Development Child and Youth Health and the Institute for Genetics, to collaboratively identify practical solutions that would benefit Canadian researchers, Research Ethics Boards, and children and families.

Abstract
RATIONALE AND OBJECTIVES Here we review the current state of multicenter radiology research (MRR), and utilize a survey of experienced researchers to identify common advantages, barriers, and resources to guide future investigators. MATERIALS AND METHODS The Association of University Radiologists established a Radiology Research Alliance task force, Multi-center Research Studies in Radiology, composed of 12 society members to review MRR. A REDCap survey was designed to gain more insight from experienced researchers. Recipients were authors identified from a PubMed database search, utilizing search terms "multicenter" or "multisite" and "radiology." The survey included investigator background information, reasons why, barriers to, and resources that investigators found helpful in conducting or participating in MRR. RESULTS The survey was completed by 23 of 80 recipients (29%), the majority (76%) of whom served as a primary investigator on at least one MRR project. Respondents reported meeting collaborators at national or international (74%) and society (39%) meetings. The most common perceived advantages of MRR were increased sample size (100%) and improved generalizability (91%). External funding was considered the most significant barrier to MRR, reported by 26% of respondents. Institutional funding, setting up a central picture archiving and communication system, and setting up a central database were considered a significant barrier by 30%, 22%, and 22% of respondents, respectively. Resources for overcoming barriers included motivated staff (74%), strong leadership (70%), regular conference calls (57%), and at least one face-to-face meeting (57%). CONCLUSIONS Barriers to MRR include funding and establishing a central database and a picture archiving and communication system. Upon embarking on an MRR project, forming a motivated team who meets and speaks regularly is essential.

Abstract
The reliability of the BACTEC MGIT 960 system for the second-line drugs (capreomycin [CPM], kanamycin [KAN], ofloxacin [OFX] and ethionamide [ETH]) susceptibility testing (DST) of Mycobacterium tuberculosis (M. tuberculosis) was compared to that of traditional Lowenstein-Jensen (L-J) proportion method (PM) among four different sites in China. After resolution of discrepant results by retesting the strains using both methods in the National Reference Laboratory of tuberculosis, the overall concordance values between the 2 systems were 99.7% (kappa value: 0.97) for CPM, 99.7% (kappa value: 0.97) for KAN, 100.0% (kappa value: 1.00) for OFX, and 98.6% (kappa value: 0.95) for ETH. The average turnaround time with BACTEC MGIT 960 system among four sites was 8.9 ± 1.7 days, significantly shorter than 28 days with the traditional L-J PM. Therefore, the BACTEC MGIT 960 system is a reliable and rapid method for the second-line drug susceptibility testing of tuberculosis in China. Notably, a stricter quality control program should be routinely carried out when clinical laboratories perform the second-line DST with BACTEC MGIT 960 system.
