Introduction

Living kidney donation is currently the most important kidney donor source in Latin America, and it is necessary to further increase its rates.

Objective

To analyze the attitude toward living kidney donation among the Santiago de Cuba's population and to determine the sociopersonal factors with which it is associated.

Method

The population over 15 years old residing in Santiago de Cuba, stratified by sex and age, was screened. The “PCID—LKD Ríos” attitude questionnaire toward living kidney donation was administered to a random selection of the people surveyed according to the stratification and the census data. The completion was anonymized and self-administered. Verbal consent was obtained.

Results

The study was completed by 445 people, of whom the 86% (n = 389) were in favor of living related kidney donation. This attitude is associated with the level of education (P < .001); previous experience with organ donation (P = .006); attitude toward cadaveric organ donation (P < .001); carrying out of prosocial activities (P = .010); discussion of the issue with the family (P < .001) and the significant other (P < .001); concern about mutilation after donation (P = .001); religious beliefs (P = .001); and assessment of the risk of living kidney donation (P < .001). In the multivariate study, the following variables persisted: (1) level of education; (2) attitude of cadaveric donation; (3) carrying out of prosocial activities; and (4) risk assessment of living donation.

Conclusions

Living related donation is very well accepted among the Santiago de Cuba's population.  相似文献

Background

The Puerto Rican population represents one of the largest immigration groups in Florida, and this has an impact on the organ transplant donation process. Our aim was to analyze attitudes toward organ donation among Puerto Ricans who currently reside in the state of Florida (USA).

Methods

The population screened consisted of individuals >15 years old, who were born in Puerto Rico, living in Florida, and awaiting organs for transplant. All participants completed the “PCID-DTO Rios” questionnaire. Random selection was done according to stratification. Support from immigration associations in Spain was needed for advice on the locations of potential respondents. Study participation was anonymized and self-administered.

Results

There were 259 respondents, 37% (n = 95) were in favor of donation, 36% (n = 93) were against donation, and 27% (n = 71) were undecided. The variables associated with these attitudes were: age (P = .017); civil status (P = .021); level of education (P < .001); previous experience with donation and transplant (P < .001); attitude toward organ donation of a relative (P < .001); carrying out pro-social activities (P < .001); discussing the issue of transplant with the family (P < .001) or couple (P < .001); attitude toward incineration (P < .001), burial (P < .001), and autopsy (P < .001); fear of mutilation after donation (P < .001); and religious beliefs (P < .001). In the multivariate study, it remained an independent variable to have discussed the issue at the family level (odds ratio = 11.627; P = .009).

Conclusion

The Puerto Rican study population residing in Florida has an unfavorable attitude toward organ donation.  相似文献

Objective

To investigate the characteristics and evolution of controlled donation after circulatory death (DCD) type III.

Materials and Methods

Observational and retrospective study of controlled DCD type III of donors conducted from 2014 to 2016. Clinical data, intensive care unit (ICU) stay, cause of death, warm ischemia time, and total time were collected. Delayed graft function (DGF) and survival of renal transplant were also registered. Qualitative variables are described as frequencies and absolute values and quantitative variables as medians and interquartile ranges.

Results

A total of 21 donors were collected; 71% (15) were males, median age was 55 years (interquartile range [IR] 48–72), and median ICU stay was 7 days (IR 4–12). The main cause of death was anoxic encephalopathy (57%, 12), followed by intracerebral hemorrhage (28%, 6). In 48%, withdrawal of life support occurred in the operating room, and 98% of donors were preserved by abdominal super-rapid cannulation technique. Average warm ischemia time was 20 minutes (IR 16–24), and total ischemia time was 26 minutes (IR 23–34). Of the donations, 57% were livers and 90% were kidneys. Out of 42 kidneys donated, 54% (23) of them were valid. Median renal transplant hospital stay was 18 days (IR 6–24), and 46% develop DGF. Survival at discharge was 100%.

Conclusion

DCD type III ensures a source of organs. The main cause of death was anoxic encephalopathy. Most donors were able to donate some solid organ.  相似文献
