Immunol Lett 2021 May 2. Epub 2021 May 2.

SCU-CUHK Joint Laboratory for Reproductive Medicine, Key Laboratory of Birth Defects and Related Diseases of Women and Children (Sichuan University), Ministry of Education, Department of Pediatrics, West China Second University Hospital, Sichuan University, Chengdu 610041, People's Republic of China. Electronic address:

The number and function of T cells are abnormal as observed in cystic fibrosis (CF) patients and CF mouse models, and our previous work shows that the CFTR mutant leads to deficiency of primitive and definitive hematopoietic in zebrafish. However, the functions and underlying mechanisms of CFTR in T cell development during early embryogenesis have not been explored. Here, we report that the genetic ablation of CFTR in zebrafish resulted in abrogated embryonic T lymphopoiesis, which was ascribed to impaired thymic homing and expansion of hematopoietic stem cells (HSCs).

NeuroCrypt: Machine Learning Over Encrypted Distributed Neuroimaging Data.

Neuroinformatics 2021 May 4. Epub 2021 May 4.

Georgia State University, Atlanta, GA, USA.

The field of neuroimaging can greatly benefit from building machine learning models to detect and predict diseases, and discover novel biomarkers, but much of the data collected at various organizations and research centers is unable to be shared due to privacy or regulatory concerns (especially for clinical data or rare disorders). In addition, aggregating data across multiple large studies results in a huge amount of duplicated technical debt and the resources required can be challenging or impossible for an individual site to build. Training on the data distributed across organizations can result in models that generalize much better than models trained on data from any of organizations alone. Read More

Synovial Cell Count Before Reimplantation Can Predict the Outcome of Patients with Periprosthetic Knee Infections Undergoing Two-stage Exchange.

Clin Orthop Relat Res 2021 05 3. Epub 2021 May 3.

T. Ascione, P. Pagliano, Department of Infectious Diseases, D. Cotugno Hospital, AORN dei Colli - Naples.

Background: Although synovial fluid can be used to diagnose periprosthetic joint infections (PJI) effectively, only the cutoff values adopted at the time of PJI diagnosis have been standardized, and few data are currently available about effectiveness of synovial fluid examination before definitive reimplantation.

Questions/purposes: We asked: (1) What are the most appropriate thresholds for synovial fluid leukocyte counts (WBC) and neutrophil percentage (PMN percentage) in a patient group undergoing definitive reimplantation after an uninterrupted course of antibiotic therapy for chronic PJI? (2) What is the predictive value of our synovial WBC and PMN percentage threshold compared with previously proposed thresholds?

Methods: In all, 101 patients with PJI were evaluated for inclusion from January 2016 to December 2018. Nineteen percent (19 of 101) of patients were excluded because of the presence of a chronic inflammatory disease, acute/late hematogenous infection, low amount of synovial fluid for laboratory investigations or infection persistence after spacer placement, and adequate antibiotic therapy.
