The majority of blood screening methods employed by blood banks do not incorporate iron-status markers, which may result in potential subclinical iron deficiency. The aim of this study was to evaluate the effects of repeated blood donation on the levels of iron in the body and to guide blood donors in preventing the depletion of iron stores. Methods: Regular blood donors were categorised into distinct groups according to the number of donations they gave, and then the correlation between these groups and their bodies’ iron levels was examined. Different parameters were employed to identify iron deficiency and iron depletion in blood donors: serum ferritin, mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH), mean corpuscular haemoglobin concentration (MCHC), total iron-binding capacity (TIBC), and serum iron. Results: The study included 300 individuals who regularly and willingly donated blood. There were no iron insufficiency cases among those donating blood for the first time (Group I). However, 15.5% of individuals who had donated once before (Group II) had ferritin levels of 15 - 30 μg/dl (ng/ml), indicating reduced iron stores. The rate increased to 18% (37 out of 206 individuals) among regular blood donors (Groups III, IV, and V). Iron deficiency (depletion) prevalence among regular blood donors in Groups III, IV, and V was 5.9% (12 out of 206) and 50.4% (100 out of 206). Donors who had donated blood most frequently had the lowest levels of haematological markers MCH, MCHC, and TIBC. Provide the p-values representing the differences between the means of MCV, MCH, iron, TIBC, and ferritin levels when comparing donor groups with the control group (Group I) based on the frequency of donations. Indicate statistically significant differences where the p-value is less than 0.0125. This significance level is adjusted based on the Bonferroni method, considering multiple independent tests. The result shows that the Iron parameter for the comparison between Group I and Group III and Group I and Group IV suggests a statistically significant difference in iron levels between these donor groups. Conclusion: The findings of this study show that a higher times of donations lads to a higher occurrence of depleted iron stores and subsequent erythropoiesis with iron deficiency by one donor from every three healthy donors. The iron and ferritin concentrations were within the normal range in group one (Control group) and reduced in the other four groups (G-2 to G-5). However, the level of haemoglobin remained within an acceptable range for blood donation. This outcome suggests that it may be necessary to reassess the criteria for accepting blood donors. The average serum ferritin levels were examined in all five groups (G-1 to G-5), both for males and females, and significant variations were seen among the groups under study. This study found that 35% of the individuals who regularly donate blood have iron-deficient anaemia (sideropenia). This suggests that it would be beneficial to test for serum ferritin at an earlier stage, ideally after three donations.展开更多

Twenty-four patients with rheumatic heart valve diseases scheduled for open heart surgery were selected and divided randomly into group A (intraoperative autologous blood donation and tepid temperature, nasopharyngeal temperature was at 32-34 ℃ during CPB) and group B (control, nasopharyngeal temperature was at 25-28 ℃ during CPB). The plasmatic concentrations of GMP-140 and D-Dimer and the plasmatic activities of 6- ketoPGF1α and AT- Ⅲ were measured by using ELISA or substrate luminescence techniques before operation, at the end of CPB, after discontinuation of CPB and postoperatively. Red blood cell count, platelet count, hematocrit, the amount of blood drainage and the amount of blood transfusion needed were measured or recorded postoperatively. The results showed the plasmatic concentrations of GMP140 and D-Dimer in group A were significantly less (P<0. 05) than those in group B during and after operation. The activity of 6-keto--PGF1α in group A was higher (P<0. 05) than that in group B during and after operation. The AT- Ⅲ activity in group A was less (P<0. 05) during CPB but higher 30 min after discontinuation of CPB than that in group B. The amount of postoperative blood loss (283± 166 versus 722± 194 ml, P<O. 01) and amount of blood transfusion (816±126 versus 1443± 678 ml, P<0. 01) in group A were significantly less than those in group B, respectively. The red blood cell count, platelet count and hematocrit in group A were significantly higher than those in group B after operation. The results suggests intraoperative autologous blood donation and tepid temperature have a good protection on blood system and can reduce postoperative non-surgical bleeding.展开更多

Because a shortage of organ donation is a serious social issue in Japan, various solutions to the issue have been considered. Although it was believed that the most critical factor in the organ shortage was the absence of a well-established social system, no prior studies attempted to analyze the issue from the perspective of the mechanisms and organizational behaviors. To identify common success factors of increasing organ donation, we conducted a qualitative survey in 5 countries promoting organ donations on a national level and increasing the number of organ donations. We found several important common factors: 1) to change from an explicit consent system to a presumed consent system with establishment of an appropriate in-hospital system, 2) to increase the level of job satisfaction of healthcare professionals and help them generating better results, 3) to demonstrate managements’ leadership for all staff to realize the importance of organ donations, 4) to establish an environment where medical professionals engaged in organ donations can appreciate autonomous working styles, the recognition of the importance of the work. It is suggested that these successful factors are introduced into Japan with long-, mid-term strategy to enhance organ donation.展开更多

This success is owed to the progress made in many fields such as surgery, immunology…However, in our country Morocco, we are faced with reluctance to donate. The study’s objective is to evaluate the perception of organ donation among university students. Methods: We conducted this cross-sectional study with descriptive and analytical aims. Our target population consisted of 991 university students from eight higher education structures. An anonymous questionnaire was distributed to those students by a single interviewer. The questions of the survey answered four main themes. Thus, two types of studies were done. The first was a descriptive study of the socio-demographic characteristics of the selected population and their knowledge and attitudes about organ donation. The second was an analytical study of the correlation between the socio-demographic characteristics, type and level of education of the target population and their knowledge and attitudes towards organ donation. Results: 97.2% of the respondents have already heard about organ donation. If 836 of the students (84.4%) thought that transplantation could be an effective therapeutic alternative, 155 of the students (15.6%) were not aware of this possibility. Furthermore, 298 students, which means 30.1% of the students, did not know that organ transplantation was practiced in Morocco. The causes of refusal found in our study were numerous. 68.5% of students blamed the lack of information as the main cause of their reluctance. 64.7% were afraid of organ trafficking. 41.1% refused the idea of mutilating the body of the deceased, which could impact the funeral. 37.3% thought that donation would be a violation of the human body according to religious values. 33.9% were against donation because they hoped that the brain-dead patient could wake up. The main results of our survey showed the very favorable attitude towards organ donation and transplantation, despite the lack of knowledge on the subject. Conclusion: This study revealed the absence of information on the practice of organ transplantation in Morocco and the underestimation of the number of people waiting for transplantation. On the other hand, like the data found in the literature, our study highlights the religious obstacles and the lack of confidence in the legislation governing donation and transplantation in our country.展开更多

The objective of the study was to make an assessment of the pre-donation capillary hemoglobin dosage for the year 2020 of the fixed collection, of the Blood Transfusion Center of Yamoussoukro. Method: This is a retrospective study that took place at the Yamoussoukro Blood Transfusion Center. The data collection related to all old and new blood donors were deemed suitable for the fixed collection of the year 2020. The method chosen for the pre-donation control is that of the portable hemoglobinometer of the HémoCue<sup>®</sup> type, more precisely 201+. Results: Of the 1160 blood donors in the study, the pre-donation hemoglobin level was not measured in 787 (67.8%) subjects of either sex. Of the subjects who had a pre-donation hemoglobin level performed, 97 (26%) blood donors had a sub-standard hemoglobin level, including 15 females and 82 males. Conclusion: Pre-donation hemoglobin testing of blood donors is effective in Yamoussoukro. However, efforts must still be made to improve the quality of the blood collected and to protect blood donors.展开更多

文摘There is shortage of organs,including kidneys,worldwide.Along with deceased kidney transplantation,there is a significant rise in live kidney donation.The prevalence of prediabetes(PD),including impaired fasting glucose and impaired glucose tolerance,is on the rise across the globe.Transplant teams frequently come across prediabetic kidney donors for evaluation.Prediabetics are at risk of diabetes,chronic kidney disease,cardiovascular events,stroke,neuropathy,retinopathy,dementia,depression and nonalcoholic liver disease along with increased risk of all-cause mortality.Unfortunately,most of the studies done in prediabetic kidney donors are retrospective in nature and have a short follow up period.There is lack of prospective long-term studies to know about the real risk of complications after donation.Furthermore,there are variations in recommendations from various guidelines across the globe for donations in prediabetics,leading to more confusion among clinicians.This increases the responsibility of transplant teams to take appropriate decisions in the best interest of both donors and recipients.This review focuses on pathophysiological changes of PD in kidneys,potential complications of PD,other risk factors for development of type 2 diabetes,a review of guidelines for kidney donation,the potential role of diabetes risk score and calculator in kidney donors and the way forward for the evaluation and selection of prediabetic kidney donors.
文摘BACKGROUND Organ donation is a critical issue that is receiving greater attention worldwide.In Jordan,the public’s knowledge about and attitudes toward organ donation play a significant role in the availability of organs for transplantation.AIM To assess the public knowledge about and attitudes toward organ donation in Jordan.METHODS A cross-sectional design was used to collect data from 396 Jordanian citizens via an online self-reported questionnaire.RESULTS Overall,396 participants were recruited.Of the entire sample,93.9%of the participants had heard about and had sufficient knowledge about organ donation but they had limited knowledge about brain death.The most common source of information about organ donation was social media networks.Females were found to score significantly higher than males for attitude.Those who had thought about organ donation or registered their names to donate scored signi-ficantly higher in terms of attitudes to donation than their counterparts who had not.The most common reasons for limited organ donation practices in Jordan were a lack of awareness programs and insufficient knowledge in society.CONCLUSION Greater public understanding of organ donation appears to be associated with more positive attitudes toward organ donation.Most participants responded positively regarding their attitude toward organ donation as they believed that this action could give another person a chance to live.Moreover,most agreed that they would donate their organs after their death.Otherwise,the participants had limited general knowledge about brain death,and most had not registered their names to donate their organs.These findings indicate the need for public awareness campaigns and educational programs to encourage more people to become organ donors.
文摘BACKGROUND Liver grafts from donation after circulatory death(DCD)are associated with a higher risk of early graft dysfunction,determined by the warm ischemia and cold ischemia times.It is essential to have precise criteria to identify this complication in order to guide therapeutic strategies.AIM To validate different graft and recipient survival scores in patients undergoing liver transplantation(LT)with DCD grafts.METHODS A retrospective and observational unicentric study was conducted on 65 LT patients with grafts obtained from controlled DCD donors from November 2013 to November 2022.The United Kingdom(UK)risk score,early allograft dysfunction(EAD)Olthoff score,and model for early allograft function(MEAF)score were used to evaluate the risk of graft and recipient survival post-transplant.For survival analysis purposes,we used the Kaplan-Meier method,and the differences between subgroups were compared using the log-rank(Mantel-Cox)test.RESULTS Sixty-five patients were included in the study.The UK risk score did not demonstrate predictive capacity for recipient or graft survival.However,in donors aged over 70 years old(18.4%),it significantly predicted graft survival(P<0.05).According to Kaplan-Meier survival curves,graft survival rates at 6 months,2 years,and 5 years in the futility group dramatically decreased to 50%compared to the other groups(log-rank 8.806,P<0.05).The EAD Olthoff and MEAF scores did not demonstrate predictive capacity for recipient or graft survival.Based on Kaplan-Meier survival curves,patients with a MEAF score≥7 had a lower graft survival rate at 6 months,2 years,and 5 years compared to patients with a lower MEAF score(log-rank 4.667,P<0.05).CONCLUSION In our series,both UK DCD risk score and MEAF score showed predictive capability for graft survival.
文摘Introduction: One of the most frequent observations in long-term blood donation is chronic iron deficiency, which can develop into anaemia. The majority of blood screening methods employed by blood banks do not incorporate iron-status markers, which may result in potential subclinical iron deficiency. The aim of this study was to evaluate the effects of repeated blood donation on the levels of iron in the body and to guide blood donors in preventing the depletion of iron stores. Methods: Regular blood donors were categorised into distinct groups according to the number of donations they gave, and then the correlation between these groups and their bodies’ iron levels was examined. Different parameters were employed to identify iron deficiency and iron depletion in blood donors: serum ferritin, mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH), mean corpuscular haemoglobin concentration (MCHC), total iron-binding capacity (TIBC), and serum iron. Results: The study included 300 individuals who regularly and willingly donated blood. There were no iron insufficiency cases among those donating blood for the first time (Group I). However, 15.5% of individuals who had donated once before (Group II) had ferritin levels of 15 - 30 μg/dl (ng/ml), indicating reduced iron stores. The rate increased to 18% (37 out of 206 individuals) among regular blood donors (Groups III, IV, and V). Iron deficiency (depletion) prevalence among regular blood donors in Groups III, IV, and V was 5.9% (12 out of 206) and 50.4% (100 out of 206). Donors who had donated blood most frequently had the lowest levels of haematological markers MCH, MCHC, and TIBC. Provide the p-values representing the differences between the means of MCV, MCH, iron, TIBC, and ferritin levels when comparing donor groups with the control group (Group I) based on the frequency of donations. Indicate statistically significant differences where the p-value is less than 0.0125. This significance level is adjusted based on the Bonferroni method, considering multiple independent tests. The result shows that the Iron parameter for the comparison between Group I and Group III and Group I and Group IV suggests a statistically significant difference in iron levels between these donor groups. Conclusion: The findings of this study show that a higher times of donations lads to a higher occurrence of depleted iron stores and subsequent erythropoiesis with iron deficiency by one donor from every three healthy donors. The iron and ferritin concentrations were within the normal range in group one (Control group) and reduced in the other four groups (G-2 to G-5). However, the level of haemoglobin remained within an acceptable range for blood donation. This outcome suggests that it may be necessary to reassess the criteria for accepting blood donors. The average serum ferritin levels were examined in all five groups (G-1 to G-5), both for males and females, and significant variations were seen among the groups under study. This study found that 35% of the individuals who regularly donate blood have iron-deficient anaemia (sideropenia). This suggests that it would be beneficial to test for serum ferritin at an earlier stage, ideally after three donations.
文摘To facilitate the implementation of controlled donation after circulatory death(cDCD)programs even in hospitals not equipped with a local Extracorporeal Membrane Oxygenation(ECMO)team(Spokes),some countries and Italian Regions have launched a local cDCD network with a ECMO mobile team who move from Hub hospitals to Spokes for normothermic regional perfusion(NRP)implantation in the setting of a cDCD pathway.While ECMO teams have been clearly defined by the Extracorporeal Life Support Organization,regarding composition,responsibilities and training programs,no clear,widely accepted indications are to date available for NRP teams.Although existing NRP mobile networks were developed due to the urgent need to increase the number of cDCDs,there is now the necessity for transplantation medicine to identify the peculiarities and responsibility of a NRP team for all those centers launching a cDCD pathway.Thus,in the present manuscript we summarized the character-istics of an ECMO mobile team,highlighting similarities and differences with the NRP mobile team.We also assessed existing evidence on NRP teams with the goal of identifying the characteristic and essential features of an NRP mobile team for a cDCD program,especially for those centers who are starting the program.Differences were identified between the mobile ECMO team and NRP mobile team.The common essential feature for both mobile teams is high skills and experience to reduce complications and,in the case of cDCD,to reduce the total warm ischemic time.Dedicated training programs should be developed for the launch of de novo NRP teams.
文摘Objective:To assess the management effect of comprehensive nursing management on blood donation services in blood stations.Methods:Sixty-four individuals who donated blood at a blood station between September 2021 and September 2023 were selected and randomly assigned into two groups of 32 each.The first group received comprehensive nursing management,while the second group received routine nursing management.Blood donation indexes and observational indexes such as adverse reactions were compared between the groups.Results:The total blood donation volume and qualified blood donation volume were higher in the first group than in the second group.The amount of discarded blood and the rate of blood discards were lower in the first group compared to the second group(P<0.05).Additionally,the adverse reaction rate in the first group was lower,the blood donation comfort scores were higher,the psychological state scores were lower,and the quality of care scores were higher than those in the second group(P<0.05).Conclusion:Comprehensive nursing management can improve the efficiency of blood donation,reduce the rate of blood discards,decrease the incidence of adverse reactions,alleviate negative psychological states of blood donors,and enhance both the comfort level of blood donation and the quality of care provided.
文摘The effects of the intraoperative autologous bind donation and tepid temperature cardiopulmonary bypass (CPB) on blood system were investigated. Twenty-four patients with rheumatic heart valve diseases scheduled for open heart surgery were selected and divided randomly into group A (intraoperative autologous blood donation and tepid temperature, nasopharyngeal temperature was at 32-34 ℃ during CPB) and group B (control, nasopharyngeal temperature was at 25-28 ℃ during CPB). The plasmatic concentrations of GMP-140 and D-Dimer and the plasmatic activities of 6- ketoPGF1α and AT- Ⅲ were measured by using ELISA or substrate luminescence techniques before operation, at the end of CPB, after discontinuation of CPB and postoperatively. Red blood cell count, platelet count, hematocrit, the amount of blood drainage and the amount of blood transfusion needed were measured or recorded postoperatively. The results showed the plasmatic concentrations of GMP140 and D-Dimer in group A were significantly less (P<0. 05) than those in group B during and after operation. The activity of 6-keto--PGF1α in group A was higher (P<0. 05) than that in group B during and after operation. The AT- Ⅲ activity in group A was less (P<0. 05) during CPB but higher 30 min after discontinuation of CPB than that in group B. The amount of postoperative blood loss (283± 166 versus 722± 194 ml, P<O. 01) and amount of blood transfusion (816±126 versus 1443± 678 ml, P<0. 01) in group A were significantly less than those in group B, respectively. The red blood cell count, platelet count and hematocrit in group A were significantly higher than those in group B after operation. The results suggests intraoperative autologous blood donation and tepid temperature have a good protection on blood system and can reduce postoperative non-surgical bleeding.

文摘Background:Grafts from older donors after circulatory death were associated with inferior outcome in liver transplants in the past.But it has seemed to remain controversial in the last decade,as a result of modified clinical protocols,selected recipients,and advanced technology of organ perfusion and preservation.The present study aimed to examine the impact of older donor age on complications and survival of liver transplant using grafts from donation after circulatory death(DCD).Methods:A total of 944 patients who received DCD liver transplantation from 2015 to 2020 were included and divided into two groups:using graft from older donor(aged≥65 years,n=87)and younger donor(age<65 years,n=857).Propensity score matching(PSM)was applied to eliminate selection bias.Results:A progressively increased proportion of liver transplants with grafts from older donors was observed from 1.68%to 15.44%during the study period.The well-balanced older donor(n=79)and younger donor(n=79)were 1:1 matched.There were significantly more episodes of biliary nonanastomotic stricture(NAS)in the older donor group than the younger donor group[15/79(19.0%)vs.6/79(7.6%);P=0.017].The difference did not reach statistical significance regarding early allograft dysfunction(EAD)and primary non-function(PNF).Older livers had a trend toward inferior 1-,2-,3-year graft and overall survival compared with younger livers,but these differences were not statistically significant(63.1%,57.6%,57.6%vs.76.9%,70.2%,67.7%,P=0.112;64.4%,58.6%,58.6%vs.76.9%,72.2%,72.2%,P=0.064).The only risk factor for poor survival was ABO incompatible transplant(P=0.008)in the older donor group.In the subgroup of ABO incompatible cases,it demonstrated a significant difference in the rate of NAS between the older donor group and the younger donor group[6/8(75.0%)vs.3/14(21.4%);P=0.014].Conclusions:Transplants with grafts from older donors(aged≥65 years)after circulatory death are more frequently associated with inferior outcome compared to those from younger donors.Older grafts from DCD are more likely to develop NAS,especially in ABO incompatible cases.
文摘Deceased organ donation is much less prominent in Japan than it is in Western and other Asian countries. Because a shortage of organ donation is a serious social issue in Japan, various solutions to the issue have been considered. Although it was believed that the most critical factor in the organ shortage was the absence of a well-established social system, no prior studies attempted to analyze the issue from the perspective of the mechanisms and organizational behaviors. To identify common success factors of increasing organ donation, we conducted a qualitative survey in 5 countries promoting organ donations on a national level and increasing the number of organ donations. We found several important common factors: 1) to change from an explicit consent system to a presumed consent system with establishment of an appropriate in-hospital system, 2) to increase the level of job satisfaction of healthcare professionals and help them generating better results, 3) to demonstrate managements’ leadership for all staff to realize the importance of organ donations, 4) to establish an environment where medical professionals engaged in organ donations can appreciate autonomous working styles, the recognition of the importance of the work. It is suggested that these successful factors are introduced into Japan with long-, mid-term strategy to enhance organ donation.
文摘Patients with end-stage renal disease in Greece are facing long waiting times to receive a kidney transplant from a deceased donor.Living kidney donation offers a valuable alternative that provides optimal outcomes and significantly expands the donor pool but still remains relatively underutilised.Developments around the world in the field of kidney transplantation mandate a change in current practice to include additional options for living donation through paired exchange,antibody-incompatible transplantation and other strategies,following careful consideration of the cultural and ethical factors involved in these complex clinical decisions.An increase in living donation rates may be achieved in several ways,including targeted campaigning to overcome potential barriers.Educating clinicians on transplantation will prove as equally important as informing patients and prospective donors but requires training and resources.Adoption of established practices and implementation of new strategies must be tailored to the needs of the Greek donor and recipient population.Local beliefs about donation,perception of associated risk and other social characteristics must be considered in the design of future strategies.Facilitating living donation in a safe environment with appropriate donor and recipient education will form the solid foundation of a new era of kidney transplantation in Greece.
文摘Plasma therapy is an extensively used treatment for critically unwell patients.For this procedure,a legitimate plasma donor who can continue to supply plasma after healing is needed.However,significant dangers are associated with supply management,such as the ambiguous provenance of plasma and the spread of infected or subpar blood into medicinal fabrication.Also,from an ideological standpoint,less powerful people may be exploited throughout the contribution process.Moreover,there is a danger to the logistics system because there are now just some plasma shippers.This research intends to investigate the blockchain-based solution for blood plasma to facilitate authentic plasma transfer.Blockchain parameters,including electronic identification,chain code,and certified ledgers,have the potential to exert a substantial,profound influence on the distribution and implementation process of blood banks.To understand the practical ramifications of blockchain,the current study provides a proof of concept approach that aims to simulate the procedural code of modern plasma distribution ecosystems using a blockchain-based architecture.The agent-based modeling used in the testing and evaluation mimics the supply chain to assess the blockchain’s feasibility,advantages,and constraints for the plasma.

文摘BACKGROUND The Hispanic community has a high demand for organ donation but a shortage of donors.Studies investigating factors that could promote or hinder organ donation have examined emotional video interventions.Factors acting as barriers to organ donation registration have been classified as:(1)Bodily integrity;(2)medical mistrust;(3)“ick”-feelings of disgust towards organ donation;and(4)“jinx”-fear that registration may result in one dying due to premeditated plans.We predict that by providing necessary information and education about the donation process via a short video,individuals will be more willing to register as organ donors.AIM To determine perceptions and attitudes regarding barriers and facilitators to organ donation intention among Hispanic residents in the New York metropolitan area.METHODS This study was approved by the Institutional Review Board at Northwell Health.The approval reference number is No.19-0009(as presented in Supplementary material).Eligible participants included Hispanic New York City(NYC)residents,18 years of age and above,who were recruited voluntarily through Cloud Research and participated in a larger randomized survey study of NYC residents.The survey an 85-item Redcap survey measured participant demographics,attitudes,and knowledge of organ donation as well as the intention to register as an organ donor.Attention checks were implemented throughout the survey,and responses were excluded for those who did fail.Participants were randomly assigned two-between subject conditions:To view a short video on organ donation and then proceed to complete the survey(i.e.,video first)and view the same video at the end of the survey(video last).No intra-group activities were conducted.This study utilized an evidenced-based emotive educational intervention(video)which was previously utilized and was shown to increase organ donation registration rates at the Ohio Department of Motor Vehicles.Results were analyzed using Jamovi statistical software.Three hundred sixty-five Hispanic individuals were included in the analysis.Once consent was obtained and participants entered the survey(the survey sample is presented in Supplementary material),participants were asked to report on demographic variables and their general impression of organ donation after death.The video depicted stories regarding organ donation after death from various viewpoints,including from the loved ones of a deceased person who died waiting for a transplant;from the loved ones of a deceased person whose organs were donated upon death;and,from those who were currently waiting for a transplant.RESULTS Using a binomial logistic regression,the analysis provides information about the relationship between the effects of an emotive video and the intention to donate among Hispanic participants who were not already registered as donors.The willingness to go back and register was found to be significantly more probable for those who watched the emotive video before being asked about their organ donation opinions(odds ratio:2.05,95%confidence interval:1.06-3.97).Motivations for participation in organ donation were also captured with many stating the importance of messages coming from“people like me”and a message that highlights“the welfare of those in need”.Overall,the findings suggest that using an emotive video that addresses organ donation barriers to prompt organ donation intentions can be effective among the Hispanic populous.Future studies should explore using targeted messaging that resonates with specific cultural groups,highlighting the welfare of others.CONCLUSION This study suggests that an emotive educational intervention is likely to be effective in improving organ donation registration intent among the Hispanic population residing in NYC.
文摘Background: Organ transplantation has helped improve the quality of life of patients with lethal terminal organ failure. This success is owed to the progress made in many fields such as surgery, immunology…However, in our country Morocco, we are faced with reluctance to donate. The study’s objective is to evaluate the perception of organ donation among university students. Methods: We conducted this cross-sectional study with descriptive and analytical aims. Our target population consisted of 991 university students from eight higher education structures. An anonymous questionnaire was distributed to those students by a single interviewer. The questions of the survey answered four main themes. Thus, two types of studies were done. The first was a descriptive study of the socio-demographic characteristics of the selected population and their knowledge and attitudes about organ donation. The second was an analytical study of the correlation between the socio-demographic characteristics, type and level of education of the target population and their knowledge and attitudes towards organ donation. Results: 97.2% of the respondents have already heard about organ donation. If 836 of the students (84.4%) thought that transplantation could be an effective therapeutic alternative, 155 of the students (15.6%) were not aware of this possibility. Furthermore, 298 students, which means 30.1% of the students, did not know that organ transplantation was practiced in Morocco. The causes of refusal found in our study were numerous. 68.5% of students blamed the lack of information as the main cause of their reluctance. 64.7% were afraid of organ trafficking. 41.1% refused the idea of mutilating the body of the deceased, which could impact the funeral. 37.3% thought that donation would be a violation of the human body according to religious values. 33.9% were against donation because they hoped that the brain-dead patient could wake up. The main results of our survey showed the very favorable attitude towards organ donation and transplantation, despite the lack of knowledge on the subject. Conclusion: This study revealed the absence of information on the practice of organ transplantation in Morocco and the underestimation of the number of people waiting for transplantation. On the other hand, like the data found in the literature, our study highlights the religious obstacles and the lack of confidence in the legislation governing donation and transplantation in our country.
文摘Introduction: Despite the progress recorded at the level of transfusion safety in Côte d’Ivoire, much remains to be done, particularly at the level of the medical selection of blood donors. The objective of the study was to make an assessment of the pre-donation capillary hemoglobin dosage for the year 2020 of the fixed collection, of the Blood Transfusion Center of Yamoussoukro. Method: This is a retrospective study that took place at the Yamoussoukro Blood Transfusion Center. The data collection related to all old and new blood donors were deemed suitable for the fixed collection of the year 2020. The method chosen for the pre-donation control is that of the portable hemoglobinometer of the HémoCue<sup>®</sup> type, more precisely 201+. Results: Of the 1160 blood donors in the study, the pre-donation hemoglobin level was not measured in 787 (67.8%) subjects of either sex. Of the subjects who had a pre-donation hemoglobin level performed, 97 (26%) blood donors had a sub-standard hemoglobin level, including 15 females and 82 males. Conclusion: Pre-donation hemoglobin testing of blood donors is effective in Yamoussoukro. However, efforts must still be made to improve the quality of the blood collected and to protect blood donors.
文摘The standard approach to organ preservation in liver transplantation is by static cold storage and the time between the cross-clamping of a graft in a donor and its reperfusion in the recipient is defined as cold ischemia time(CIT).This simple definition reveals a multifactorial time frame that depends on donor hepatectomy time,transit time,and recipient surgery time,and is one of the most important donor-related risk factors which may influence the graft and recipient’s survival.Recently,the growing demand for the use of marginal liver grafts has prompted scientific exploration to analyze ischemia time factors and develop different organ preservation strategies.This review details the CIT definition and analyzes its different factors.It also explores the most recent strategies developed to implement each timestamp of CIT and to protect the graft from ischemic injury.
文摘BACKGROUND With an ongoing demand for transplantable organs,optimization of donor management protocols,specifically in trauma populations,is important for obta-ining a high yield of viable organs per patient.Endocrine management of brain-dead potential organ donors(BPODs)is controversial,leading to heterogeneous clinical management approaches.Previous studies have shown that when levo-thyroxine was combined with other treatments,including steroids,vasopressin,and insulin,BPODs had better organ recovery and survival outcomes were increased for transplant recipients.AIM To determine if levothyroxine use in combination with steroids in BPODs increased the number of organs donated in trauma patients.METHODS A retrospective review of adult BPODs from a single level 1 trauma center over ten years was performed.Exclusion criteria included patients who were not solid organ donors,patients who were not declared brain dead(donation after circulatory death),and patients who did not receive steroids in their hospital course.Levothyroxine and steroid administration,the number of organs donated,the types of organs donated,and demographic information were recorded.Univariate analyses were performed with P<0.05 considered to be statistically significant.RESULTS A total of 88 patients met inclusion criteria,69(78%)of whom received levothyroxine and steroids(ST/LT group)vs 19(22%)receiving steroids without levothyroxine(ST group).No differences were observed between the groups for gender,race,pertinent injury factors,age,or other hormone therapies used(P>0.05).In the ST/LT group,68.1%(n=47)donated a high yield(3-5)of organ types per donor compared to 42.1%(n=8)in the ST group(P=0.038).There was no difference in the total number of organ types donated between the groups(P=0.068).CONCLUSION This study suggests that combining levothyroxine and steroid administration increases high-yield organ donation per donor in BPODs in the trauma patient population.Limitations to this study include the retrospective design and the relatively small number of organ donors who met inclusion criteria.This study is unique in that it mitigates steroid administration as a confounding variable and focuses specifically on the adjunctive use of levothyroxine.
