ABSTRACT
ABSTRACT The no-touch saphenous vein with surrounding pedicle tissue harvesting technique preserved endothelium and vessel wall integrity and demonstrated improved long-term saphenous vein conduit patency that was comparable to internal thoracic artery conduit patency. Despite improved saphenous vein conduit patency rates, there is a possibility that no-touch saphenous vein harvest may increase wound complication rates by increased tissue disruption, including venous and lymphatic channels. Comprehensive strategies to minimize leg wound complications after no-touch saphenous vein harvest are discussed.
ABSTRACT
Abstract Objective To elaborate a protocol for the harvest, transport, and preservation of human osteochondral tissue for use in tissue banks (TBs). Methods Osteochondral fragments measuring 2 cm3 of 5 corpse donors aged between 15 and 45 years old were analyzed. The samples were stored in cell preservation medium containing: human albumin, Iscove's and vancomycin preserved at 4ºC. The concentration of proteoglycans in the extracellular medium was quantified by the use of Safranin-O, while tissue structural analysis was assessed by histological study with hematoxylin-eosin stained slides. The images obtained were analyzed according to the histological scores of Mankin and the score proposed by the OsteoArthritis Research Society International. The samples were analyzed with 0, 15, 30 and 45 days of preservation. Results The osteochondral fragments studied showed a progressive decrease in proteoglycan concentration with increased preservation time. After 30 days of preservation, structural changes were identified with discontinuity of the cartilage surface layer. According to the results obtained by the Mankin score, there was a statistically significant difference between 15 and 30 days of tissue preservation. Conclusion The protocol described defined knee transport immersed in Lactated Ringer at a controlled temperature of 10º C until its arrival at the TB. After processing, the preservation solution was composed of Iscove's serum-free cell culture medium supplemented with 10% human albumin and 100 µg/ml vancomycin. The tissue was preserved at a temperature of 4ºC until the moment of transplantation characterizing the fresh preservation.
Resumo Objetivo Elaborar um protocolo para a captação, transporte e preservação de tecido osteocondral humano para utilização em banco de tecidos (BT). Métodos Foram analisados fragmentos osteocondrais com dimensão de 2 cm3 de 5 doadores cadáveres com idades entre 15 e 45 anos. As amostras foram armazenadas em meio de preservação celular contendo: albumina humana, Iscove's e vancomicina preservados à temperatura de 4ºC. A concentração de proteoglicanos no meio extracelular foi quantificada pelo uso de Safranina-O, enquanto a análise estrutural do tecido foi avaliada através de estudo histológico com lâminas coradas em hematoxilina-eosina. As imagens obtidas foram analisadas segundo os escore histológicos de Mankin e o escore proposto pela OsteoArthritis Research Society International. As amostras foram analisadas com 0, 15, 30 e 45 dias de preservação. Resultados Os fragmentos osteocondrais estudados apresentaram diminuição progressiva na concentração de proteoglicanos com o aumento do tempo de preservação. Após 30 dias de preservação, foram identificadas alterações estruturais com descontinuidade da camada superficial da cartilagem. Segundo os resultados obtidos pelo escore de Mankin, houve diferença com significância estatística entre 15 e 30 dias de preservação do tecido. Conclusão O protocolo descrito definiu o transporte de joelho em bloco imerso em Ringer Lactato em temperatura controlada a 10ºC até sua chegada ao BT. Após o processamento, a solução de preservação foi composta por meio de cultura celular sem soro Iscove's suplementado com albumina humana a 10% e vancomicina 100 µg/mL. O tecido foi preservado à temperatura de 4ºC até o momento do transplante caracterizando a preservação a fresco.

Objetivo identificar os motivos da recusa de córneas. Método estudo transversal, retrospectivo, descritivo e correlacional, composto por 5.560 córneas ópticas. As informações foram extraídas do banco de dados da Central de Notificação, Captação e Doação de Órgãos (CNCDO), bem como de prontuários de doadores. A estatística descritiva foi utilizada para a análise das variáveis categóricas e testes específicos, com nível de significância de 5% para avaliar as associações entre as variáveis. Este estudo atendeu aos aspectos éticos da pesquisa científica. Resultados 60% dos doadores eram do sexo masculino e 40% morreram por problemas circulatórios. Os principais motivos de recusa informados pelas equipes de transplante são a idade do doador e a contagem de células endoteliais. Para cada ano adicionado à idade do doador, há uma redução de 1% na chance de que essa córnea seja usada para transplante, e para cada acréscimo de 100 células por mm2 aumenta as chances de que essa córnea seja usada em 9%. Conclusão a principal causa de recusa na aceitação do tecido corneano está relacionada à idade e à contagem de células endoteliais.
Objective to identify the reasons for refusal of corneas. Method this was a cross-sectional, retrospective, descriptive and correlational study composed of 5,560 optical corneas. The information was taken from the notification, organ procurement and distribution centers database as well as donor records. Descriptive statistics were used for the analysis of categorical variables and specific tests with a significance level of 5% for assessing the associations between variables. This study met the ethical aspects of scientific research. Results 60% of the donors were male and 40% died by circulatory problems. The main reason for refusal as informed by transplant teams is the donor's age and the endothelial cell count. For each year added to the donor's age, there is a 1% decrease in the chance that this cornea will be used for transplantation, and the increase of 100 cells per mm2 increases the chances that this cornea will be used by 9%. Conclusion the main cause of refusal in the acceptance of corneal tissue is related to the age and the endothelial cell count.

ABSTRACT
Objective To investigate the protective effect of salvianolate against bile duct injury after donation after cardiac death (DCD) liver transplantation and its clinical application prospect. Methods Sixty recipients of DCD liver transplantation were randomly divided into two groups with 30 cases in each group. Salvianolate (250mg/d) was given daily for 14 days after operation in treatment group, and the same amount of normal saline was given in control group. The therapeutic regimen of anti-rejection and anti-infection is the same between the two groups. The incidence of early graft dysfunction (EAD), and the serous levels of total bilirubin (TB), alkaline phosphatase (ALP), γ-glutamyltransferase (GGT), total bile acid (TBA) 1 month, 6 months and 12 months after liver transplantation were compared between the two groups. Also, the platelets (PLT), prothrombin time (PT), activated partial prothrombin time (APTT) and fibrinogen (FIB) were compared between the two groups at 2 weeks after operation. Results There was no significant difference in baseline parameters between the two groups (P>0.05). Compared with the control group, the incidence of EAD was decreased in treatment group, but there was no significant difference [10.0%(3/30) vs. 23.3%(7/30), P=0.166]. The serous levels of TB, ALP, GGT and TBA in treatment group were lower than those in control group 1 month, 6 months and 12 months after operation: [TB: 1 month, (28.5±17.0)μmol/L vs. (39.8±20.1)μmol/L, P=0.025; 6 months, (24.5±10.6)μmol/L vs. (33.3±16.4) μmol/L, P=0.018; 12 months, (19.8±9.5)μmol/L vs. (26.4±14.1)μmol/L, P=0.037, ALP: 1 month, (147.3±76.9)U/L vs. (187.6±70.9)U/L, P=0.039; 6 months, (163.0±61.4)U/L vs. (198.1±51.6)U/L, P=0.020; 12 months, (167.9±59.9)U/L vs. (200.2±56.2)U/L, P=0.036, GGT: 1 month, (83.9±49.5)U/L vs. (113.6±61.1)U/L, P=0.043; 6 months, (130.9±48.7)U/L vs. (169.7±77.0)U/L, P=0.023; 12 months, (154.7±45.1)U/L vs. (182.5±59.8)U/L, P=0.047, TBA: 1 month, (6.6±2.1)μmol/L vs. (8.0±2.4)μmol/L, P=0.016; 6 months, (9.5±2.2)μmol/L vs. (12.1±3.4)μmol/L, P=0.001; 12 months, (12.5±2.7)μmol/L vs. (5.6±3.8)μmol/L, P=0.001]. However, there was no significant difference in PLT, PT, APTT and FIB between two groups [PLT: (148.6±88.6)×109/L vs. (152.8±74.4)×109/L, P=0.843; PT: (12.9±1.1)s vs. (13.0±1.1)s, P=0.617; APTT: (34.6±3.7)s vs. (34.9±3.4)s, P=0.716; FIB: (3.4±0.6)g/L vs. (3.2±0.6)g/L, P=0.270, repectively]. Conclusions Salvianolate has a protective effect against bile duct injury after DCD liver transplantation, and does not increase the risk of postoperative bleeding.
ABSTRACT
ABSTRACT Eye banks use sterile procedures to manipulate the eye, antiseptic measures for ocular surface decontamination, and rigorous criteria for donor selection to minimize the possibility of disease transmission due to corneal grafting. Donor selection focuses on analysis of medical records and specific post-mortem serological tests. To guide and standardize procedures, eye bank associations and government agencies provide lists of absolute and relative contraindications for use of the tissue based on donor health history. These lists are guardians of the Hippocratic principle "primum non nocere." However, each transplantation carries risk of transmission of potentially harmful agents to the recipient. The aim of the procedures is not to eliminate risk, but limit it to a reasonable level. The balance between safety and corneal availability needs to be maintained by exercising prudence without disproportionate rigor.
RESUMO Os bancos de olhos utilizam procedimentos estéreis na manipulação dos olhos, medidas antissépticas para a descontaminação da superfície ocular e critério rigoroso de seleção do doador. Essa seleção é feita por meio do prontuário médico e de testes sorológicos específicos post mortem. Para orientá-la e uniformizá-la, as associações de bancos de olhos e órgãos governamentais fornecem listas de contraindicações absolutas e relativas de uso do tecido, baseadas nas condições prévias de saúde do doador. Essas listas são as guardiãs do princípio de Hipócrates "primum non nocere" e, como tal, são conservadoras. Entretanto, cada transplante traz o risco de transmissão de agentes potencialmente nocivos ao receptor. O objetivo não é eliminar esse risco, mas limitá-lo a um nível razoável. Existe um equilíbrio entre a segurança e a disponibilidade de córneas. A sabedoria está em manter esse equilíbrio, exercendo a prudência sem rigor exagerado.

ABSTRACT
The goal of auricular cartilage harvest is to obtain a sufficient amount for reconstruction and to minimize the change in ear shape. The cartilage can be harvested by a posterior or anterior approach, and each method has advantages and disadvantages. The posterior approach presents the advantage of scar concealment, but there are limits to the amount of cymba cartilage that may be harvested. In contrast, the anterior approach may cause a noticeable scar. However, as cartilage is collected, the anterior approach provides a view that facilitates the preservation ear structure. In addition, it is possible to obtain a greater amount of cartilage. From January 2014 to December 2015, we harvested auricular cartilage graft material in 17 patients. To prevent the development of trapdoor scars or linear scar contracture, short incisions were made on the superior border of the cymba and cavum. Two small and narrow incisions were made, resulting in suboptimal exposure of the surgical site, which heightens the potential for damaging the cartilage when using existing tools. To minimize this, the authors used a newly invented ball-type elevator. All patients recovered without complications after surgery and reported satisfaction with the shape of the ear.

The most common anatomic variant seen in donor kidneys for renal transplantation is the presence of multiple renal arteries, which can cause an increased risk of complications. Accessory renal arteries should be anastomosed to the proper source arteries to improve renal perfusion via the appropriate vascular reconstruction techniques. In microsurgery, 2 kinds of vascular augmentation methods, known as ‘supercharging’ and ‘turbocharging,’ have been introduced to ensure vascular perfusion in the transferred flap. Supercharging uses a distant source of the vessels, while turbocharging uses vascular sources within the same flap territory. These technical concepts can also be applied in renal transplantation, and in this report, we describe 2 patients who underwent procedures using supercharging and turbocharging. In one case, the ipsilateral deep inferior epigastric artery was transposed to the accessory renal artery (supercharging), and in the other case, the accessory renal artery was anastomosed to the corresponding main renal artery with a vascular graft (turbocharging). The transplanted kidneys showed good perfusion and proper function. No cases of renal failure, hypertension, rejection, or urologic complications were observed. These microsurgical techniques can be safely utilized for renal transplantation with donor kidneys that have multiple arteries with a lower complication rate and better outcome.

Abstract Objective: We investigated the effects of pedicled and semiskeletonized left internal mammary artery (LIMA) harvesting techniques on postoperative drainage in patients subjected to off-pump CABG, ignoring other advantages or disadvantages of those techniques. Methods: The present study comprises a total of 160 subjects that underwent coronary artery bypass surgery in our clinic. Data were collected consecutively and retrospectively. An attempt was made to have similar groups in terms of demographic characteristics. Patients that underwent off-pump coronary artery bypass surgery by two surgical teams which differed only in LIMA harvesting technique were dichotomized and compared according to these techniques. The first group (Group 1) consisted of patients in whom LIMA was harvested with surrounding tissues using the pedicled technique. The second group (Group 2) consisted of patients in whom LIMA was harvested using the semiskeletonized technique, with the veins separated from surrounding connective tissues. Results: The mean amount of drainage in the first 24 hours was 706.1±234.2 ml vs. 591±258.8 ml (Group 1 vs. Group 2; P=0.005), the mean amount of drainage in the second 24 hours was 270±133.6 ml vs. 189.4±140.4 ml (Group 1 vs. Group 2; P<0.001), and the mean amount of total drainage was determined to be 976.1±306.9 ml vs. 781.2±335.5 ml (Group 1 vs. Group 2; P<0.001). Conclusion: It was observed that semiskeletonized LIMA presents reduced amount of postoperative drainage in the first and second 24-hour periods and total amount of drainage than pedicled LIMA, independent of pleural integrity.

Abstract Objectives: to report the results of evaluation regarding changes in the number of potential donor referrals, actual donors, and conversion rates after the implementation of an in-house organ and tissue donation for transplantation coordination project. Methods: epidemiological study, both retrospective and transversal, was performed with organ donation data from the Secretariat of Health for the State and the in-house organ donation coordination project of a beneficent hospital. The data was compared using nonparametric statistical Mann-Whitney test, and the Student's t-test, considering a significance level of 5% (p <0.05). Results: there were statistically significant differences (p < 0.05), before and after the implementation of the project on the number of potential donor notification/month (3.05 - 4.7 ), number of actual donor/month (0.78 to 1.60) and rate of conversion ( 24.7 to 34.8 %). The hospitals 1, 2, 7 and 8 had significant results in potential donor, actual donor or conversion rate. Conclusion: the presence of an in-house coordinator is promising and beneficial, the specialist is important to change the indicators of efficiency, which consequently reduces the waiting lists for organ transplants.

OBJECTIVE To evaluate the viability of a professional specialist in intra-hospital committees of organ and tissue donation for transplantation. METHODS Epidemiological, retrospective and cross-sectional study (2003-2011 and 2008-2012), which was performed using organ donation for transplants data in the state of Sao Paulo, Southeastern Brazil. Nine hospitals were evaluated (hospitals 1 to 9). Logistic regression was used to evaluate the differences in the number of brain death referrals and actual donors (dependent variables) after the professional specialist started work (independent variable) at the intra-hospital committee of organ and tissue donation for transplantation. To evaluate the hospital invoicing, the hourly wage of the doctor and registered nurse, according to the legislation of the Consolidation of Labor Laws, were calculated, as were the investment return and the time elapsed to do so. RESULTS Following the nursing specialist commencement on the committee, brain death referrals and the number of actual donors increased at hospital 2 (4.17 and 1.52, respectively). At hospital 7, the number of actual donors also increased from 0.005 to 1.54. In addition, after the nurse started working, hospital revenues increased by 190.0% (ranging 40.0% to 1.955%). The monthly cost for the nurse working 20 hours was US$397.97 while the doctor would cost US$3,526.67. The return on investment was 275% over the short term (0.36 years). CONCLUSIONS This paper showed that including a professional specialist in intra-hospital committees for organ and tissue donation for transplantation proved to be cost-effective. Further economic research in the area could contribute to the efficient public policy implementation of this organ and tissue harvesting model.
OBJETIVO Avaliar a viabilidade de profissional especialista em comissões intra-hospitalares de doação de órgãos e tecidos para transplantes. MÉTODOS Estudo epidemiológico, retrospectivo e transversal (2003 a 2011 e 2008 a 2012), realizado com dados de doação de órgãos para transplantes no estado de São Paulo. Foram avaliados nove hospitais (hospitais 1 a 9). Foram avaliadas, por regressão logística, diferenças em número de notificações de morte encefálica e doadores efetivos (variáveis dependentes) após a entrada do profissional especialista (variável independente) na comissão intra-hospitalar de doação de órgãos e tecidos para transplantes. Para avaliação do faturamento hospitalar, foram calculados o salário-hora de médico e enfermeiro, conforme legislação da Consolidação das Leis do Trabalho, o retorno e o prazo do retorno do investimento. RESULTADOS Após a entrada de enfermeiro especialista na comissão, as notificações de morte encefálica e o número de doadores efetivos aumentaram no hospital 2 (4,17 e 1,52, respectivamente). No hospital 7, o número de doadores efetivos também aumentou de 0,005 para 1,54. E, após entrada de enfermeiro especialista, o faturamento hospitalar aumentou em 190,0% (variação de 40,0% a 1.955%). O custo mensal para 20 horas semanais do enfermeiro foi R$940,00 e, do médico, R$8.330,00. O retorno do investimento foi de 275%, em curto prazo (0,36 anos). CONCLUSÕES A inserção de profissional especialista nas comissões intra-hospitalares para captação de doação de órgãos e tecidos para transplantes mostra-se custo-efetiva. Novos estudos econômicos na área podem contribuir com uma política pública eficiente de implantação desse modelo de captação de órgãos e tecidos para transplantes.

Objective To analyze the outcomes of renal transplantation from donation after citizen death (DCD) in our single center.Method We retrospectively investigated the recipient outcomes of renal allografts from DCD.Between November 2010 and 31st December 2014,our institution performed 242 renal transplants from DCD.Outcome variables (survival of recipients/allografts and adverse events) and characteristics of marginal donor transplants were analyzed.Result There were 139 males and 44 females in the enrolled 183 donors,and the range of age was from 2 days to 68 years.183 donors included 102 cases of donation after brain death (category Ⅰ),22 cases of donation after circulatory death (category Ⅱ) and 59 cases of donation after brain death followed by circulatory death (category Ⅲ).Utilizing these renal allografts,we performed 242 kidney transplantations including 237 single kidney transplants and 5 pediatric en bloc kidney transplants.The age of recipients ranged from 12 to 64 years.The data indicated that the 1-year recipient/allograft survival rate was 93.8% and 90.5%,respectively.The rate of delayed graft function (DGF) was 33.1 %,higher than that from executed prisoners allografts (23.6%,P<0.05).However,the rate of 1-year acute rejection,interstitial pneumonia and the other adverse events (urinary fistula,ureteral obstruction and cardiac and cerebral vascular accident,etc.) was similar to that from executed prisoners allografts.In addition,good results from pediatric and elder donor renal transplantation were shown in our data,even though the discard rate of elder donor kidney was high.Conclusion By comprehensive evaluation,strictly screening donors and enhancing the rnanagenent of donors,the long-term survival of recipients may be prolonged and the incidence of DGF and primary graft non-function (PNF) may be decreased.The marginal donors from pediatric and elder DCD donors could be utilized in clinical transplantation safely and effectively as long as reasonable evaluation was carried out.
ABSTRACT
BACKGROUND:By analyzing the current difficulties faced by human organ transplantation and social factors which lead to organ transplant donor shortage in China, people are found to be generaly lack of knowledge about organ transplant and donation process. OBJECTIVE: To make a tentative probe into the construction of organ donation social mission system on four aspects, namely the importance, ethical principles, current situation and countermeasures, and to provide scientific advice and information for organ donation publicity and education. METHODS: Articles about organ donation and organ transplantation were retrieved from CQVIP, CNKI, Wanfang, PubMed, Medline System from January 2005 to November 2014 with the key words of “organ donation, organ transplantation, shortage of donor, body donation, education system” in both Chinese and English. After secondary manual retrieval of organ donation coordinator, literature were included if they involved organ donation coordinator and organ donation and transplantation related policies and regulations. This paper put forward countermeasures for the construction of human organ donation social mission system in China based on the literature induction. RESULTS AND CONCLUSION:This paper describes the necessity of organ donation education system, systematicaly analyzes the existing problems for current organ donation education problems and ethical principles that should be folowed, and explore the construction strategy of human organ donation social mission system in China. The way to relieve tension of organ transplant donor and expand donor sources is to win broad support and understanding of citizens, which can ensure the sustainable development of organ donation work. So, it is very important to build the human organ donation social mission system.
ABSTRACT
The aim of this study was to describe the harnessing of corneas captured and processed for transplantation in an ocular tissue bank in north-eastern Brazil. This was a transverse and retrospective study, with a sample group of 612 individuals whose corneas were donated and captured between January/2007 and July/2012. This study was approved by the Research Ethics Committee under number 007.0.294.000-10, and research was based on an instrument consisting of social, demographic and clinical data of the donors. Of the 1209 corneas captured, 868 were used and 341 were discarded. Of the 612 donors, the corneas of 597 (97.5%) were captured from both eyes, being that 423 (70.9%) of these corneas were used. Further studies are required on the reasons for discarding corneas and clarifications as to the conduct of professionals when processing corneas, considering the increase in the quantity of donors and the elevated number of discarded ocular tissue.
