Impact of previous high-dose therapy on outcome after allografting for multiple myeloma

We describe a single centre experience of 33 patients allografted for multiple myeloma, of which 28 received matched sibling marrow, one haploidentical family donor marrow and four matched but unrelated donor marrow. Median follow-up after transplant is 27 months, and 13 patients are currently alive. One out of four patients with an unrelated donor survives and 12 out of 28 (42.8%) with matched sibling donors. Four patients were unevaluable because of early death (相似文献   

Abstracts

Dental enamel is the most mineralized tissue of vertebrate organisms. Enamel biosynthesis is initiated by the secretion, processing, and self-assembly of a complex mixture of proteins. The formation of an ordered enamel organic extracellular matrix (ECM) seems be a crucial step for the proper formation of mineral phase. Polarizing microscopy demonstrates that the ordered supramolecular structure of the secretory-stage enamel organic ECM is strongly birefringent. In the present work we analyzed the birefringence of secretory-stage enamel organic ECM in amelogenin (Amelx)- and enamelysin (Mmp20)-deficient mice. Female Amelx^+/? animals showed significant reduction in optical retardation values when compared with the Amelx^+/+ subgroup (p = 0.0029). The secretory-stage enamel organic ECM of the Amelx^?/? subgroup did not exhibit birefringence. The secretory-stage enamel organic ECM of Mmp20^?/? mice showed a significant decrease in optical retardation as compared with Mmp20^+/+ and Mmp20^+/? mice (p = 0.0000). Mmp20^+/? and Mmp20^+/+ mice exhibited similar birefringence (p = 1.0000). The results presented here support growing evidence for the idea that the birefringence of secretory-stage enamel organic ECM is influenced by the ordered supramolecular organization of its components.     

Perceptions and Attitudes Towards Organ Donation Among People Seeking Healthcare in Tertiary Care Centers of Coastal South India

Background:

Organ transplantation is the most preferred treatment modality for end-stage organ diseases. The need for the transplants is higher than the availability. Prerequisites for the success of transplantation program include awareness and positive attitudes.

Aim:

To assess the perceptions and attitudes of the people seeking health care in tertiary care centers towards organ donation in Mangalore, India.

Settings and Design:

This cross-sectional study included 863 people seeking general healthcare as outpatients.

Materials and Methods:

Face to face interviews were carried out using pretested tools which included the socio demographic data. Data was analyzed using Statistical Package for Social Sciences version 11.5.

Results:

Overall, 59.6% participants showed the willingness to donate organs. Females (64.1%) and participants from upper socio economic status (62.7%) had higher willingness rates for organ donations. Hindus (63.6%) and Christians (63.3%) had higher willingness rates for organ donations than Muslims (38.2%). Also, 23.7% participants showed willingness to donate eyes and 33.6% wished to donate any organ after death. Most of the participants (67%) were aware that money should not be accepted for donating organs, and 58.1% were aware that it is an offence to accept any benefit for organ donations. Forty percent participants had perceived risks associated with organ donation. Regarding donor cards, 42.3% of the participants knew about it and 3.7% already possessed it.

Conclusion:

It is apparent from the study that though there was high level of awareness about organ donation, a high proportion of the participants did not have positive attitudes towards organ donation.
