Elevation of early plasma biomarkers in patients with clinical risk factors predicts the increased nonrelapse mortality after allogeneic hematopoietic stem cell transplantation: Biomarkers for nonrelapse mortality.

Transplant Cell Ther 2021 May 11. Epub 2021 May 11.

First Department of Internal Medicine, Kansai Medical University, Osaka 573-1010, Japan.

Background: Early prediction of nonrelapse mortality (NRM) in patients who undergo allogeneic hematopoietic stem cell transplantation (aHSCT) based on the results of laboratory tests are challenging. There is, therefore, a need for evaluation of biomarkers for prediction of nonrelapse mortality, which is a major problem that offsets the advantages of aHSCT.

Objectives: We tested the validity and efficacy of two plasma biomarkers (ST2 and Reg3α) based on the Mount Sinai Acute GVHD International Consortium (MAGIC) algorithm for early prediction of NRM in Japanese patients who underwent aHSCT. Read More

Human and Environmental Physiology Research Unit, School of Human Kinetics, University of Ottawa, Ottawa, Canada Departments of Medicine, Cardiac Sciences and Community Health Sciences Faculties of Medicine and Kinesiology, University of Calgary, Canada Clinical Epidemiology Program, Ottawa Hospital Research Institute, Ottawa, Canada FAME Laboratory, Department of Exercise Science, University of Thessaly, Greece Faculté des sciences de l'activité physique, Université de Sherbrooke, Sherbrooke, Québec, Canada Hypertension Program, Division of Nephrology, University of Ottawa, Ottawa, Canada.

Purpose: To mitigate rises in core temperature >1°C, the American Conference of Governmental Industrial Hygienists (ACGIH) recommends upper limits for heat stress (Action Limit Values; ALV), defined by wet-bulb globe temperature (WBGT) and a worker's metabolic rate. However, these limits are based on data from young men and are assumed to be suitable for all workers, irrespective of age or health status. We therefore explored the impact of aging, type 2 diabetes (T2D), and hypertension (HTN), on tolerance to prolonged, moderate-intensity work above and below these limits. Read More
