Haemovigilance is a system with standard program to cover the entire transfusion chain, monitor, evaluate and analyse the data to improve patients’ safety. We report the implemented haemovigilance system in hospitals and transfusion reactions (TR) in Iran. Methods and Materials: This was a prospective descriptive study. The national reporting system for transfusion incidents was introduced in ...

BACKGROUND Tick-borne illnesses were diagnosed in a group of National Guard members, including some who had donated blood a few days before the onset of symptoms. A voluntary recall of those blood components was issued and a multistate investigation was conducted to determine if transfusion-transmitted illness had occurred. STUDY DESIGN AND METHODS Donors and recipients were asked to complete...

BACKGROUND Variant Creutzfeldt-Jakob disease (vCJD) is a novel human prion disease caused by infection with the agent of bovine spongiform encephalopathy (BSE). Epidemiological evidence does not suggest that sporadic CJD is transmitted from person to person via blood transfusion, but this evidence may not apply to vCJD. We aimed to identify whether vCJD is transmissible through blood transfusio...

Transfusion medicine is traditionally a strong/fundamental part of clinical practice, saving hundreds millions lives. However, blood-borne or transmitted infections are well-known and feared possibility, risk we relentlessly mitigate. Pathogens continuously rather quickly changing, so during the last decade, many, sometimes exotic, new pathogens diseases were recorded analyzed, some them proved...

When merging belief functions, Dempster rule of combination is justified only when sources can be considered as independent. When dependencies are ill-known, it is usual to ask the merging operation to satisfy the property of idempotence, as this property ensures a cautious behaviour in the face of dependent sources. There are different strategies to find such rules for belief functions. One st...

The charter of SRC i s t o a d v ance both the state of knowledge and the state of the art in computer systems. From our establishment in 1984, we have performed basic and applied research to support Digital's business objectives. Our current work includes exploring distributed personal computing on multiple platforms, networking, programming technology, system modelling and management techniqu...

We overview the existing conditional independence concepts from the viewpoint of their relation to possibility theory. We will show that a suitable notion — from this perspective — seems to be strong independence in the wider framework of credal sets.

Possibility is considered as a promising mathematical tool to represent that particular case of incomplete information given by a measurement result. A measurement result can be affected by systematic and random effects. The combination of random contributions in the possibility theory returns only approximated results, and it is important to identify an optimal combination method to obtain acc...
