Clinicopathological Aspects and Inflammation-Immune Markers in Alcohol and/or Hepatitis C Virus-Induced Hepatocellular Carcinoma Patients Treated With Sorafenib.

Background: Tyrosine kinase inhibitors have been used to treat hepatocellular carcinoma (HCC), but the outcomes of patients under treatment vary. Since the roles of clinicopathological aspects and markers of chronic inflammation/immune homeostasis in the outcome of HCC patients treated with sorafenib are still unclear, these were the aims of this study. Methods: Patients with alcohol-induced and/or hepatitis C virus (HCV)-induced HCC (n = 182) uniformly treated with sorafenib were included in the study. Baseline clinicopathological aspects of patients were computed from the medical records. The neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), lymphocyte-to-monocyte ratio (LMR), systemic inflammation response index (SIRI), and systemic immune-inflammation index (SII) were obtained from the hematological exam performed before the administration of sorafenib. Overall survival (OS) was analyzed using Kaplan-Meier probabilities, log-rank test, and univariate and multivariate Cox proportional hazard ratio (HR) analyses. Results: In multivariate analysis, alpha-foetoprotein (AFP) level and Child-Pugh score were predictors of OS. Patients with AFP levels higher than 157 ng/mL and Child-Pugh B or C had 1.40 (95% confidence interval (CI): 1.03 - 1.91, P = 0.03) and 1.64 (95% CI: 1.07 - 2.52, P = 0.02) more chances of evolving to death than the remaining patients, respectively. NLR, PLR, LMR, SIRI, and SII did not alter the OS of HCC patients. Conclusions: AFP level and Child-Pugh score act as independent prognostic factors in patients with alcohol and/or HCV-induced HCC treated with sorafenib, but markers of chronic inflammation/immune homeostasis seem not to alter the outcome of patients with HCC induced by alcohol and/or HCV.

Perioperative analysis of patients undergoing liver transplantation at the Hospital de Clínicas da Unicamp in the context of the SARS-CoV-2 pandemic / Análise perioperatória dos pacientes submetidos a transplante hepático no Hospital de Clínicas da Unicamp no contexto da pandemia de SARS-CoV-2

Introduction: SARS-CoV-2 began in 2020 and caused important changes in the number of transplants performed in hospitals and in the protocols for admitting candidates to perform the procedure. The Brazilian Association of Organ Transplantation (ABTO) recommends not performing transplants from donors with active COVID-19 infection, positive test results or with Severe Acute Respiratory Syndrome. The hepatic repercussions related to COVID-19 are presented in some reports in the medical literature. Liver changes resulting from other corona viruses such as SARS-CoV and MERS-CoV are well documented. The Hospital de Clínicas of the State University of Campinas is a tertiary center that performs solid organ transplants. Objectives: To carry out a perioperative, retrospective, descriptive analysis of liver transplants in the context of the SARS-CoV-2 pandemic carried out at the Hospital das Clínicas of the State University of Campinas from March 2020 to July 2021. Materials and Methods: Retrospective, descriptive, longitudinal cohort study based on the review of medical records of patients undergoing liver transplantation in the context of the SARS-CoV-2 pandemic from March 2020 to July 2021 at the clinical hospital of the State University of Campinas. Results: Retrospective analysis was performed on 57 patients in the period. Only 1 patient needed to be excluded because he was under 18 years old. Of the 56 patients, 52 underwent RT-PCR laboratory testing and chest tomography (CT). Of these 52 patients, only 2 tested positive, one pre-transplant (TX) and one post-operatively (post-op). Regarding chest CT scans, none of them showed typical changes for COVID pre-TX, in the post-op 4 patients presented typical chest CT scans. The average age was 55.86 years. The mortality rate was 38% and no deaths were attributed to COVID 19. The average MELD-Na scale was 20.94. Conclusion: The present study carried out at the Hospital de Clínicas da Unicamp analyzed the clinical, laboratory and radiological association to better elucidate the variables determined by COVID-19 in its diagnosis and in-hospital management. It is concluded that the SARS-CoV-2 pandemic had an impact on the routine of liver transplantation worldwide and on the service in which the study was carried out.

Introdução: A pandemia causada pelo SARS-CoV-2 teve início no ano de 2020 e ocasionou mudanças importantes no número de transplantes realizados nos hospitais e nos protocolos de admissão de candidatos para realização do procedimento. A Associação Brasileira de Transplante de Orgãos (ABTO) recomendava não realizar transplante de doadores com infecção COVID-19 ativa, teste positivo ou com Síndrome Respiratória Aguda Grave. As repercussões hepáticas relacionadas a COVID-19 são apresentadas em alguns relatos presentes na literatura médica. Estão bem documentadas as alterações hepáticas decorrentes de outros coronavírus tais como SARS-CoV e MERS-CoV. O Hospital de Clínicas da Universidade Estadual de Campinas é um centro terciário que realiza transplantes de órgãos sólidos. Objetivos: Realizar a análise retrospectiva descritiva perioperatória dos transplantes hepáticos no contexto da pandemia por SARS-CoV-2 realizados no hospital das clínicas da Universidade Estadual de Campinas no período de Março de 2020 a Julho de 2021. Materiais e Métodos: Estudo retrospectivo, descritivo de coorte longitudinal baseado na revisão dos prontuários dos pacientes submetidos ao transplante hepático no contexto da pandemia por SARS-CoV-2 no período de Março de 2020 a Julho de 2021 no hospital de clínicas da Universidade Estadual de Campinas. Resultados: A análise retrospectiva foi realizada em 57 pacientes no período. Apenas 1 paciente precisou ser excluído por ter menos de 18 anos. Dos 56 pacientes, 52 realizaram coleta do exame laboratorial RT-PCR e tomografia (TC) de tórax. Desses 52 pacientes apenas 2 positivaram o exame, um pré transplante (TX) e um no pós-operatório (pós-op). Em relação às TC de tórax nenhuma apresentava alterações típicas para COVID pré TX, no pós-op 4 pacientes apresentaram TC típicas. A média de idade foi de 55,86 anos. A taxa de mortalidade foi de 38% e nenhum óbito foi atribuído ao COVID 19. A escala de MELDNa média foi de 20,94. Conclusão: O presente estudo realizado no Hospital de Clínicas da Unicamp analisou a associação clínica, laboratorial e radiológica para melhor elucidar as variáveis determinadas pela COVID-19 no seu diagnóstico e manejo intra-hospitalar. Conclui-se que a pandemia por SARS-CoV-2 teve impacto na rotina de realização do transplante hepático mundialmente e no serviço no qual o estudo foi realizado.

Results of Green Indocyanine in the Use of the R1T1 Robot as Aid in the Pre-operative Process of Hepatic Organ Transplant: Experiment in Wistar Rats.

Since the beginning of the history of transplants, numerous difficulties have been faced in the effective implementation of this therapeutic practice, especially with regard to the transplantation of solid organs and their teaching and training, together with the time of removal and transplantation of the organ that directly influences the results of the transplant surgical procedure. The objective of this research was to demonstrate the results found on the process of using green indocyanine during the invention of the Automatic Portable Surgical Communication Equipment with the Robot R1T1 (APSCERR), as well as to demonstrate its capabilities in the medical area of organ transplantation. Biochemical exams, liver profile exams, and mitochondrial breathing exams were performed on the control group and on the indocyanine group. The Mann-Whitney U test was used for statistical evaluations with a significance level of P < .05. As a result of this research, the effectiveness of using the APSCERR equipment on detecting the green indocyanine marker was proven, along with its ability to analyze macroscopic parameters together with the standard color "Dianin Boin scale" used to analyze the level of metabolism/reperfusion of the liver when observed with the APSCERR equipment connected to the R1T1 robot in the presence of green indocyanine. A patent for the development of APSCERR has been registered. It was possible to demonstrate the effectiveness of the equipment in detecting green indocyanine when analyzing parameters in the liver and the absence of a significant impact on the organ with the use of green indocyanine.

Proximal gastric vagotomy with drainage procedure in the treatment of stenosing duodenal ulcers

A vagotomia gástrica proximal (VGP) é a mais moderna técnica utilizada para o tratamento cirúrgico das úlceras pépticas duodenais. Nos pacientes que apresentam quadro clínico de estenose piloroduodenal, secundário a úlceras duodenais crônicas, um procedimento de drenagem pode ser associado (VGP + D). Säo apresentados os resultados obtidos em 125 doentes com estenose pilórica e duodenal, secundária a úlcera crônica, acompanhados durante os últimos 12 anos da Disciplina de Moléstias do Aparelho Digestivo da Faculdade de Ciências Médicas da UNICAMP. A média de idade foi de 38 anos e 84% foram homens e 16% mulheres. O quadro clínico foi caracterizado pela presença de dor, vômitos e perda de peso em 88,8% dos pacientes. apresentam-se ainda com sangramento (5,6%), perfuraçäo (1,6%) e associaçäo de perfuraçäo e sangramento em 4% dos pacientes. As técnicas de procedimento de drenagem utilizadas nesta casuística foram: a) técnica de Holle em 72% dos pacientes, que consiste em piloroplastia transversa; b) técnica de Jaboulay em 20% dos pacientes, que é uma gastroduodenostomia com sutura em plano único seromuscular extramucoso realizada com fios inabsorvíveis 00; c) gastroduodenostomia anterior em 6,4% dos pacientes; d) gastrojejunostomia em 1,6% dos pacientes. Esta última técnica foi realizada diante da impossibilidade de outro procedimento de drenagem. Na análise dos resultados, dividiu-se o tempo de seguimento em: seguimento imediato, considerado desde o pós-operatório até o sexto mês; seguimento tardio, após o sexto mês até a data da última revisäo feita no caso. Durante o período de seguimento imediato todos os pacientes estiveram assintomáticos. No seguimento tardio, possível em cerca de 60% dos pacientes, verificou-se cinco casos de recidiva ulcerosa (7,1%). Analisando-se estes pacientes, observou-se que quatro eram previamente portadores de úlceras duodenais e um paciente portador de úlcera pré-pilórica. Destes, somente três foram reoperados e submetidos à gastrectomia parcial e vagotomia troncular, sendo que os demais foram tratados clinicamente, recebendo bloqueadores H2 e estäo atualmente assintomáticos, com respectivamente 12 e 36 meses de seguimento...
