The etiology, treatment, and prevention of nonorganic failure-to-thrive in infants

Nonorganic failure-to-thrive is a medical-psychological disorder reflecting lack of growth in an infant without apparent physical causes. Children who fail to thrive as infants are at high risk for developmental delays, personality problems, abuse, and death. This article focuses on environmental failure-to-thrive, describing the behavioral characteristics of the nonthriving infant and the family milieu. Aspects of early environments of NOFT infants are profiled, specific intervention strategies are discussed, and recommendations regarding the promotion of intense, consistent multi-disciplinary intervention strategies are advanced.     

Xenograft rejection--all that glitters is not Gal.

Xenotransplantation is being developed in the hope of resolvingthe critical shortage of donor organs for transplantation. TheEurotransplant waiting lists [1] for donor organs of variouskinds number almost 16 000 patients and the US lists [2] morethan 90 000 patients. Renal transplantation, for instance, cost-effectivelyconfers a significant survival advantage [3] and improvementof quality of life [4]. But whereas currently, in Europe, nearly12 000 end-stage renal disease patients await a suitable donor,only 3383 kidney transplants were performed in 2005, with anaverage waiting time of 1174 days [1]. Substantial researchefforts are being made in the field of xenotransplantation,and the immunological barriers are gradually being elucidated.Pig-to-human xenogeneic
