Characterization and Function of Cryopreserved Bone Marrow from Deceased Organ Donors: A Potential Viable Alternative Graft Source.

Despite the readily available graft sources for allogeneic hematopoietic cell transplantation (alloHCT), a significant unmet need remains in the timely provision of suitable unrelated donor grafts. This shortage is related to the rarity of certain HLA alleles in the donor pool, nonclearance of donors owing to infectious disease or general health status, and prolonged graft procurement and processing times. An alternative hematopoietic progenitor cell (HPC) graft source obtained from the vertebral bodies (VBs) of deceased organ donors could alleviate many of the obstacles associated with using grafts from healthy living donors or umbilical cord blood (UCB).

Ischemia considerations for the development of an organ and tissue donor derived bone marrow bank.

Background: Deceased organ donors represent an untapped source of therapeutic bone marrow (BM) that can be recovered in 3-5 times the volume of that obtained from living donors, tested for quality, cryopreserved, and banked indefinitely for future on-demand use. A challenge for a future BM banking system will be to manage the prolonged ischemia times that are inevitable when bones procured at geographically-dispersed locations are shipped to distant facilities for processing. Our objectives were to: (a) quantify, under realistic field conditions, the relationship between ischemia time and the quality of hematopoietic stem and progenitor cells (HSPCs) derived from deceased-donor BM; (b) identify ischemia-time boundaries beyond which HSPC quality is adversely affected; (c) investigate whole-body cooling as a strategy for preserving cell quality; and (d) investigate processing experience as a variable affecting quality.

Early inflammatory markers are independent predictors of cardiac allograft vasculopathy in heart-transplant recipients.

Background: Identification of risk is essential to prevent cardiac allograft vasculopathy (CAV) and graft failure due to CAV (GFDCAV) in heart transplant patients, which account for 30% of all deaths. Early CAV detection involves invasive, risky, and expensive monitoring approaches. We determined whether prediction of CAV and GFDCAV improves by adding inflammatory markers to a previously validated atherothrombotic (AT) model.

Cost-benefit analysis of home blood pressure monitoring in hypertension diagnosis and treatment: an insurer perspective.

Home blood pressure (BP) monitoring has been shown to be more effective than clinic BP monitoring for diagnosing and treating hypertension. However, reimbursement of home BP monitoring is uncommon in the United States because of a lack of evidence that it is cost beneficial for insurers. We develop a decision-analytic model, which we use to conduct a cost-benefit analysis from the perspective of the insurer.

Value of the first post-transplant biopsy for predicting long-term cardiac allograft vasculopathy (CAV) and graft failure in heart transplant patients.

Background: Cardiac allograft vasculopathy (CAV) is the principal cause of long-term graft failure following heart transplantation. Early identification of patients at risk of CAV is essential to target invasive follow-up procedures more effectively and to establish appropriate therapies. We evaluated the prognostic value of the first heart biopsy (median: 9 days post-transplant) versus all biopsies obtained within the first three months for the prediction of CAV and graft failure due to CAV.

Centile-based early warning scores derived from statistical distributions of vital signs.

Aim Of Study: To develop an early warning score (EWS) system based on the statistical properties of the vital signs in at-risk hospitalised patients.

Materials And Methods: A large dataset comprising 64,622 h of vital-sign data, acquired from 863 acutely ill in-hospital patients using bedside monitors, was used to investigate the statistical properties of the four main vital signs. Normalised histograms and cumulative distribution functions were plotted for each of the four variables.

Continuously-infused human C-reactive protein is neither proatherosclerotic nor proinflammatory in apolipoprotein E-deficient mice.

Studies of human native C-reactive protein (nCRP) in mice have shown effects ranging from proatherogenic, to antiatherogenic, to no effect. It is likely that these disparities are related to (a) the use, in some studies, of contaminated nCRP, or to (b) variation in CRP levels associated with either its episodic administration or the use of CRP-transgenic mice. In our study, 12-week-old male apolipoprotein E-deficient (apoE (-/-)) mice, maintained on a Western diet, received azide- and endotoxin-free nCRP (n = 23) or placebo (n = 23) continuously via osmotic pumps (20.
