Training in recovery, perfusion and packaging of organs for transplants: profile of professionals and analysis of post-course learning.

OBJECTIVE: To understand the profile of professionals working in organ harvesting, and analyze the learning results of those trained before and after the course on recovery, perfusion and packaging of organs for transplants. METHODS: A retroprospective, quantitative, analytical-descriptive study about the Course on Recovery, Perfusion and Packaging of Liver and Kidney, in the period from 2012 to 2014. Pre- and post-tests, with ten questions were used to assess knowledge about organ harvesting. The association of knowledge with applied content was verified by the McNemar test. RESULTS: Of the total of 334 participants, 187 (56.0%) were physicians, 104 (31.1%) nurses, and 43 (12.9%) scrub nurses. The majority of participants was male (58.4%), mean age of 39.1 years, 50% had graduated 5 to 10 years before, and 50.4% had less than one-year experience in organ harvesting. In knowledge assessment, there was an increase in the weighted mean, from 6.1 in the pre-test to 7.9 in the post-test. A significant increase in learning was observed in the post-test in 50% of scrub nurses, 33.3% in nurses 20% in physicians. CONCLUSION: The professionals were starting work in organ harvesting, and most were from Southeastern, Northeastern and Northern regions. In terms of learning, the course contributed to enhancing knowledge of the multiprofessional health team, and represented better learning standard.

Radiological iodinated contrasts (IC) agents cause acute kidney injury (AKI). To evaluate the renoprotective effect of sodium bicarbonate (Bic) on renal function (creatinine clearance {Clcr}, Jaffé, and Clcr mL·min-1⋅100 g-1) and the oxidative profile (peroxide excretion, urinary peroxides, urinary malondialdehyde, FOX-2 expression, and thiobarbituric acid reactive substance {TBARS; nmol/mg Cr}) in rats treated with an IC agent. Adult male Wistar rats weighing 250 - 300 g were treated once daily for 5 days with one of the following treatments: saline (0.9%, 3 mL·kg-1⋅day-1intraperitoneally {i.p.}), IC agent (sodium and meglumine ioxitalamate, 3 mL/kg, i.p.), Bic + Saline (3-mL/kg Bic, i.p., 1 h before and after saline treatment), and Bic + IC (3-mL/kg Bic, i.p., 1 h before and after the IC treatment). The IC agent induced AKI, and the antioxidant renoprotective effect of Bic was confirmed (Clcr/TBARS/urinary peroxide: saline group, 0.59 ± 0.03/0.11 ± 0.02/1.29 ± 0.24; Bic + Saline group, 0.58 ± 0.03/0.13 ± 0.02/1.32 ± 0.64; IC group, 0.22 ± 0.02/0.19 ± 0.02/4.77 ± 0.24; Bic + CI group, 0.51 ± 0.04/0.13 ± 0.3/1.80 ± 0.04; p<0.05). The protective effect of Bic in the IC-induced AKI was confirmed; hence, Bic administration may be considered as a therapeutic option for patients undergoing IC-enhanced radiography.

Efeito renoprotetor dos flavonoides do vinho na nefrotoxicidade do imunossupressor Tacrolimus / Renoprotective effects of wine flavonoids in nephrotoxicity of the immunosuppressant Tacrolimus / Efecto renoprotector de los flavonoides del vino en la nefrotoxicidad del inmunosupresor Tacrolimus

OBJETIVO: Verificar o efeito renoprotetor do extrato de Vitis vinifera L na nefrotoxicidade induzida pelo Tacrolimus em estudos experimentais com ratos. MÉTODOS: Pesquisa quantitativa com modelo experimental, na qual foram utilizados ratos Wistar, machos, adultos, pesando entre 250g - 300g, tratados uma vez ao dia por cincodias, por gavagem, conforme segue: Salina (controle, cloreto de sódio 0,1ml); Vitis (Vitis vinifera L 3mg/kg), FK (0,5mg/kg) e FK+Vitis (0,5mg/kg + 3mg/kg, respectivamente) . A função renal foi avaliada por meio do clearance de creatinina (Clcr/ 100g, método Jaffé) e a peroxidação lipídica pela mensuração de peróxidos urinários (PU, FOX-2). RESULTADOS: A administração de FK elevou a excreção de peróxidos e reduziu o clearance de creatinina, e a administração simultânea com Vitis vinifera L protegeu a função renal nesses parâmetros. CONCLUSÃO: Os dados confirmaram a lesão nefrotóxica induzida pelo Tacrolimus e demonstraram o efeito renoprotetor do Vitis Vinifera L.

OBJECTIVE: To investigate the renoprotective effects of the extract of Vitis vinifera L in the Tacrolimus-induced nephrotoxicity in experimental studies with rats. METHODS: Quantitative survey with an experimental model in which adult male, Wistar rats, weighing between 250g - 300g, were used. The rats were treated once a day for cincodias by gavage as follows: Saline (control, sodium chloride, 0.1 ml); Vitis (Vitis vinifera L 3mg/kg), FK (0.5 mg / kg); and, FK + Vitis (0.5 mg / kg + 3 mg / kg, respectively). Renal function was assessed by creatinine clearance (CrCL / 100g, Jaffe method) and lipid peroxidation by measurement of urinary peroxides (PU, FOX-2). RESULTS: The administration of FK increased the excretion of peroxides and reduced creatinine clearance, and simultaneous administration with Vitis vinifera L protected the renal function in these parameters. CONCLUSION: These data confirm the injury induced by nephrotoxic Tacrolimus and demonstrated the renoprotective effect of Vitis vinifera L.
