Public financing versus private billing in a public hospital under management of a Social Health Organization.

INTRODUCTION: to assess the efficiency of management by a Social Health Organization (Organização Social de Saúde - OSS) compared with the private sector; to verify if there are savings for the State Health Secretariat (SES) in management contracts for financing the production of a public hospital versus its production values billed by private methods; and to establish if the amounts billed by the Unified Health System (SUS) table would finance the same procedures. METHODS: we compiled and tabulated all procedures performed and the materials and drugs dispensed in the Euryclides Jesus Zerbini Transplant Hospital (HTEJZ), managed by the OSS Associação Paulista Para o Desenvolvimento da Medicina (SPDM), in September, October, and November 2018, according to the Brasíndice® table for drugs, the Simpro® table for materials, the CBHPM® table for medical fees, and tables SIGTAP SUS and SIA SUS. We then compared the average values obtained in the private billing with the costing amount reimbursed by the State Health Secretariat and the billing calculated in the SIA-SUS. RESULTS: the average SUS revenue was R$ 2,774,086.91; the monthly reimbursement by the SES was R$ 13,055,700.00; and the average private revenue was R$ 25,084,440.31. CONCLUSIONS: the management by the OSS SPDM in the Euryclides de Jesus Zerbini Transplant Hospital was more efficient in the financing / production ratio than it would be to a private hospital. The economy of public funds was significant. The current SUS table reimbursement values would not meet the need for funding for an overly complex hospital.

RESUMO Objetivo: os objetivos deste estudo foram verificar a eficiência da gestão por Organização Social de Saúde (OSS) comparada com o setor privado; se há economia para a Secretaria do Estado da Saúde (SES) nos contratos de gestão para custeio da produção de um hospital público frente aos valores de produção faturada pelos métodos privados e estabelecer se os valores faturados pela tabela do Sistema Único de Saúde (SUS) financiariam os mesmos procedimentos. Métodos: foram compilados e tabelados todos os procedimentos realizados, materiais e medicamentos dispensados no âmbito do Hospital de Transplantes Euryclides de Jesus Zerbini (HTEJZ) gerido pela OSS Associação Paulista para o Desenvolvimento da Medicina (SPDM), nos meses de setembro, outubro e novembro de 2018 de acordo com a tabela do Brasíndice® para medicamentos, Simpro® para materiais, CBHPM® para honorários médicos, Tabela SIGTAP-SUS e SIA-SUS; em seguida foi realizada a comparação entre os valores médios obtidos no faturamento privado, o valor de custeio repassado pela Secretaria do Estado da Saúde e o faturamento apurado no SIA-SUS. Resultados: faturamento médio SUS de R$ 2.774.086,91; repasse mensal SES R$ 13.055.700,00; faturamento privado médio de R$ 25.084.440,31. Conclusões: a gestão pela OSS SPDM no Hospital de Transplantes Euryclides de Jesus Zerbini foi mais eficiente na relação financiamento/produção do que seria para um hospital privado. Foi muito significativa a economia para o erário público. Os atuais valores de remuneração da Tabela SUS a serem repassados não atingiriam a necessidade de custeio para um hospital de alta complexidade.

IMPACT OF KRAS MUTATIONS IN CLINICAL FEATURES IN COLORECTAL CANCER.

BACKGROUND: KRAS mutations are important events in colorectal carcinogenesis, as well as negative predictors of response to EGFR inhibitors treatment. AIM: To investigate the association of clinical-pathological features with KRAS mutations in colorectal cancer patients treated. METHODS: Data from 69 patients with colorectal cancer either metastatic at diagnosis or later, were retrospectively analyzed. The direct sequencing and pyrosequencing techniques were related to KRAS exon 2. The mutation diagnosis and its type were determined. RESULTS: KRAS mutation was identified in 43.4% of patients. The most common was c.35G>T (p.G12V), c.35G>A (p.G12D) and c.38G>A (p.G13D). No correlation was found between KRAS mutation and age (p=0.646) or gender (p=0.815). However, mutated group had higher CEA levels at admission (p=0.048) and codon 13 mutation was associated with involvement of more than one metastatic site in disease progression (p=0.029). Although there was no association between primary tumor site and mutation diagnosis (p=0.568), primary colon was associated with worse overall survival (p=0.009). CONCLUSION: The KRAS mutation was identified in almost half of patients. Mutated KRAS group had higher levels of CEA at admission and the mutation at codon 13 was associated with involvement of more than one metastatic site in the course of the disease. Colon disease was associated with the worst overall survival.

Comparison between anal cytology, high-resolution anoscopy and HPV DNA genotyping by polymerase chain reaction in the post-treatment follow-up of condylomata acuminata.

AIM: to evaluate the presence of subclinical HPV-induced anal lesions with anal cytology, High-Resolution Anoscopy (HRA) and HPV genotyping by polymerase chain reaction (PCR) in the follow-up of treated condylomata acuminata (CA). METHODS: seventy-nine male patients were included. One month after anal CA eradication, the patients underwent brush samples collection for anal cytology and PCR, and HRA with biopsy of acetowhite lesions. These methods were compared within all patients and between groups, according to Human Immunodeficiency Virus (HIV) infection status: HIV-negative; HIV-positive with TCD4 count above and below 350 cells/mm3. RESULTS: the most frequent HPV types were 6 and 16. HPV DNA was isolated in 92%. HIV infection was associated with a higher number of oncogenic HPV types (p=0.038). All patients with negative PCR had negative HRA and cytology. There were no differences in cytological, HRA or histopathological findings between groups. CONCLUSION: the association of the findings of cytopathology, HRA and genotyping of HPV refined the diagnosis of HPV-induced lesions. The degree of immunodeficiency was not associated with increase in remnant HPV-induced anal lesions.

RESUMO Racional: Mutações KRAS são eventos importantes na carcinogênese colorretal como preditores negativos de resposta ao tratamento. Objetivo: Investigar a associação de características clinicopatológicas com mutações no KRAS em pacientes com câncer colorretal tratados. Métodos: Sessenta e nove pacientes com câncer colorretal metastáticos ao diagnóstico ou posteriormente foram analisados. As técnicas de sequenciamento direto e pirosequenciamento foram relacionadas ao éxon 2 do KRAS e o diagnóstico da mutação e seu tipo foram determinados. Resultados: A mutação KRAS foi identificada em 43,4% dos pacientes, c.35G>T (p.G12V), c.35G>A (p.G12D) e c.38G>A (p.G13D). Não foi encontrada correlação entre a mutação KRAS e a idade (p=0,646) ou o gênero (p=0,815). No entanto, o grupo mutado apresentou níveis mais altos de CEA na admissão (p=0,048). A mutação do códon 13 foi associada ao envolvimento de mais de um local metastático na progressão da doença (p=0,029); não houve associação entre o local primário do tumor e o diagnóstico de mutação (p=0,568); a doença primária do cólon foi associada com pior sobrevida global (p=0,009). Conclusão: A mutação KRAS foi identificada em quase metade dos pacientes. O grupo KRAS mutado apresentou níveis mais altos de CEA na admissão e a mutação no códon 13 foi associada ao envolvimento de mais de um local metastático no curso da doença. A doença do cólon foi associada com pior sobrevida global.

RESUMO Objetivo: avaliar a presença de lesões anais subclínicas HPV-induzidas com citologia anal, colposcopia anal e genotipagem de HPV por reação em cadeia da polimerase (PCR) no seguimento de condilomas anais tratados. Método: foram incluídos 79 pacientes do sexo masculino. Após um mês da erradicação de lesões condilomatosas anais, os participantes voltaram em consulta para coleta de amostras com escova para citologia anal e PCR, e colposcopia anal com biópsia de lesões acetobrancas. Os métodos de detecção das lesões foram comparados entre os pacientes e entre grupos, de acordo com o status de infecção pelo vírus da imunodeficiência humana (HIV): HIV-negativo; HIV-positivo com TCD4 acima ou abaixo de 350 células/mm3. Resultados: os tipos de HPV mais frequentes foram 6 e 16. Infecção pelo HIV foi associada a maior número de tipos de HPV oncogênicos (p=0,038). Todos os pacientes com PCR negativo apresentaram colposcopia e citologia negativos. Não houve diferença nos achados citológico, colposcópico ou histopatológico entre grupos. Conclusão: a associação dos achados citopatológico, colposcópico e PCR melhorou a acurácia do diagnóstico de lesões anais HPV-induzidas. O grau de imunodeficiência não foi associado a maior frequência de lesões anais HPV-induzidas remanescentes.

Comparative study of four different types of intraperitoneal mesh prostheses in rats.

PURPOSE: To compare four types of mesh regarding visceral adhesions, inflammatory response and incorporation. METHODS: Sixty Wistar rats were divided into four groups, with different meshes implanted intraperitoneally: polytetrafluoroethylene (ePTFE group); polypropylene with polydioxanone and oxidized cellulose (PCD); polypropylene (PM) and polypropylene with silicone (PMS). The variables analyzed were: area covered by adhesions, incorporation of the mesh and inflammatory reaction (evaluated histologically and by COX2 immunochemistry). RESULTS: The PMS group had the lowest adhesion area (63.1%) and grade 1 adhesions. The ePTFE and PM groups presented almost the total area of their surface covered by adherences (99.8% and 97.7% respectively) The group ePTFE had the highest percentage of area without incorporation (42%; p <0.001) with no difference between the other meshes. The PMS group had the best incorporation rate. And the histological analysis revealed that the inflammation scores were significantly different. CONCLUSIONS: The PM mesh had higher density of adherences, larger area of adherences, adherences to organs and percentage of incorporation. ePTFE had the higher area of adherences and lower incorporation. The PMS mesh performed best in the inflammation score, had a higher incorporation and lower area of adherences, and it was considered the best type of mesh.

Simultaneous pancreas-kidney transplantation and the impact of postoperative complications on hospitalization cost. / Impacto das complicações pós-transplante simultâneo pâncreas-rim sobre o custo da internação hospitalar.

OBJECTIVE: considering simultaneous pancreas-kidney transplantation cases, to evaluate the financial impact of postoperative complications on hospitalization cost. METHODS: a retrospective study of hospitalization data from patients consecutively submitted to simultaneous pancreas-kidney transplantation (SPKT), from January 2008 to December 2014, at Kidney Hospital/Oswaldo Ramos Foundation (Sao Paulo, Brazil). The main studied variables were reoperation, graft pancreatectomy, death, postoperative complications (surgical, infectious, clinical, and immunological ones), and hospitalization financial data for transplantation. RESULTS: the sample was composed of 179 transplanted patients. The characteristics of donors and recipients were similar in patients with and without complications. In data analysis, 58.7% of the patients presented some postoperative complication, 21.8% required reoperation, 12.3% demanded graft pancreatectomy, and 8.4% died. The need for reoperation or graft pancreatectomy increased hospitalization cost by 53.3% and 78.57%, respectively. The presence of postoperative complications significantly increased hospitalization cost. However, the presence of death, internal hernia, acute myocardial infarction, stroke, and pancreatic graft dysfunction did not present statistical significance in hospitalization cost (in average US$ 18,516.02). CONCLUSION: considering patients who underwent SPKT, postoperative complications, reoperation, and graft pancreatectomy, as well as surgical, infectious, clinical, and immunological complications, significantly increased the mean cost of hospitalization. However, death, internal hernia, acute myocardial infarction, stroke, and pancreatic graft dysfunction did not statistically interfere in hospitalization cost.

OBJETIVO: avaliar o impacto financeiro das complicações pós-operatórias no transplante simultâneo pâncreas-rim durante a internação hospitalar. MÉTODOS: estudo retrospectivo dos dados da internação hospitalar dos pacientes submetidos consecutivamente ao transplante simultâneo pâncreas-rim no período de janeiro de 2008 a dezembro de 2014 no Hospital do Rim/Fundação Oswaldo Ramos. As principais variáveis estudadas foram a reoperação, pancreatectomia do enxerto, óbito, complicações pós-operatórias (cirúrgicas, infecciosas, clínicas e imunológicas) e os dados financeiros da internação para o transplante. RESULTADOS: a amostra foi composta de 179 pacientes transplantados. As características dos doadores e receptores foram semelhantes nos pacientes com e sem complicações. Na análise dos dados, 58,7% dos pacientes apresentaram alguma complicação pós-operatória, 21,8% necessitaram de reoperação, 12,3%, de pancreatectomia do enxerto e 8,4% evoluíram para o óbito. A necessidade de reoperação ou pancreatectomia do enxerto aumentou o custo da internação em 53,3% e 78,57%, respectivamente. A presença de complicação pós-operatória aumentou significativamente o custo. Entretanto, a presença de óbito, hérnia interna, infarto agudo do miocárdio, acidente vascular cerebral e disfunção do enxerto pancreático não apresentaram significância estatística no custo, cuja média foi de US$ 18,516.02. CONCLUSÃO: complicações pós-operatórias, reoperação e pancreatectomia do enxerto aumentaram significativamente o custo médio da internação hospitalar do SPK, assim como as complicações cirúrgicas, infecciosas, clínicas e imunológicas. No entanto, o óbito durante a internação, a hérnia interna, o infarto agudo do miocárdio, o acidente vascular cerebral e a disfunção do enxerto pancreático não interferiram estatisticamente neste custo.

Genetic variants in gastric cancer: Risks and clinical implications.

Cancer is a multifactorial disease that involves many molecular alterations. Gastric cancer (GC) is the third leading cause of cancer death worldwide. GC is a highly heterogeneous disease with different molecular and genetics features. Therefore, this review focuses on an overview of the genetic aspects of gastric cancer by highlighting the important impact and role of deletions and/or duplications of chromosomal segments, genomic variants, H. pylori infection and interleukin variants, as found in gene expression and newly proposed molecular classification studies. The challenge is to better understand the mechanisms and different pathways that lead to the development and progression of GC.

Relationship between the preoperative body mass index and the resolution of metabolic syndrome following Roux-en-Y gastric bypass.

BACKGROUND: The increased prevalence of overweight and obesity has reached alarming proportions worldwide and has serious health implications, including an association with an increase in metabolic syndrome. Among the methods to control metabolic syndrome, bariatric surgery plays an important role and can provide a significant improvement in the components of metabolic syndrome. OBJECTIVE: The aim of this study was to determine the relationship between the preoperative body mass index (BMI) and the postoperative resolution of metabolic syndrome [using the National Cholesterol Education Program (NCEP ATP III criteria)] in patients undergoing Roux-en-Y gastric bypass (RYGB). METHODS: Retrospective analysis of a consecutive series of cases, stratified by BMI into three groups (group 1, BMI <40 kg/m(2), group 2, BMI 40-49.9 kg/m(2), and group 3, BMI 50 ≥ kg/m(2)) consisting of both sexes between 20 and 60 years of age. The cohort consisted of 149 patients undergoing RYGB. Anthropometric, biochemical, and clinical evaluations were performed preoperatively and then at 30 and 180 days postoperatively. RESULTS: The average age was 40 years, and the patients were predominately female (72%). At the end of the study period, all groups showed a significant reduction in metabolic syndrome compared with preoperative levels. Logistic regression showed a higher percentage of metabolic syndrome in patients in group 3 after 180 days. CONCLUSION: There was significant resolution of metabolic syndrome in all groups, independently of the preoperative BMI. However, in group 3 (BMI ≥ 50 kg/m(2)), 22% of individuals still presented with metabolic syndrome at 180 days postoperatively (P=0.03).

Duodenum-stomach anastomosis: a new technique for exocrine drainage in pancreas transplantation.

INTRODUCTION: Poor vascular access due to previous surgery can be a major obstacle in pancreas transplantation for which new exocrine and vascular outflow techniques might be useful. A 34-year-old female with early onset type 1 diabetes who underwent living donor kidney transplantation 20 years ago and a failed pancreas transplantation 2 years ago presented for pancreas retransplantation. METHODS: The inferior vena cava was used in the previous deceased donor pancreas transplantation and both iliac arteries had intense perivascular fibrosis, making arterial anastomosis impossible. The only remaining option for the implant was the infrarenal aorta, with venous drainage to the superior mesenteric vein and exocrine drainage to the gastric antrum. RESULTS: The patient had an uneventful recovery and graft function appeared normal. This report shows that when the recipient's abdominal cavity does not provide clear access for the usual surgical techniques regarding exocrine drainage, the stomach drainage procedure is an option. CONCLUSION: Duodenum-stomach anastomosis might be an alternative to portal enteric drainage because there is easy access for graft biopsies and even for procedures involving the papilla major.

Evaluation of the efficacy and reproducibility of cholangiopancreatography by magnetic resonance for detecting biliary complications following orthotopic liver transplantation / Estudo da eficácia e da reprodutibilidade da colangiopancreatografia por ressonância magnética na detecção das complicações biliares pós-transplantes hepáticos

PURPOSE: To evaluate the accuracy and reproducibility of magnetic resonance cholangiopancreatography (MRCP) in the detection of biliary complications in liver transplanted patients. METHODS: A study was conducted, with blinded review of 28 MRCP exams of 24 patients submitted to liver transplantation. The images were reviewed by two independent observers, at two different moments, regarding the degree of biliary tree visualization and the presence or absence of biliary complications. The MRCP results were compared, when negative, to at least 3 months of clinical and biochemical follow-up, and when positive, to the findings at surgery or endoscopic retrograde cholangiopancreatography (ERCP). RESULTS: The degree of intrahepatic biliary tree visualization was considered good or excellent in 78.6 percent and 82.1 percent of the exams by the two observers and visualization of the donor duct, recipient duct and biliary anastomosis was considered good or excellent in 100 percent of the exams, by both observers. Six biliary complications were detected (21.4 percent), all of them anastomotic strictures. Intra and interobserver agreement were substantial or almost perfect (kappa k values of 0.611 to 0.804) for the visualization of the biliary tree and almost perfect (k values of 0.900 to 1.000) for the detection of biliary complications. MRCP achieved 100 percent sensitivity, 95.45 percent specificity, 85.7 percent positive predictive value and 100 percent negative predictive value for the detection of biliary complications. CONCLUSIONS: MRCP is an accurate examination for the detection of biliary complications after orthotopic liver transplantation and it is a highly reproducible method in the evaluation of the biliary tree of liver transplanted patients.

OBJETIVO: Medir a acurácia e reprodutibilidade da colangiopancreatografia por ressonância magnética (CPRM) na avaliação da visibilização de complicações biliares em pacientes submetidos a transplantes hepáticos ortotópicos. MÉTODOS: Realizado estudo retrospectivo de 28 exames de CPRM de 24 pacientes submetidos a transplantes hepáticos. Os exames foram interpretados por dois observadores independentes, em dois momentos distintos, quanto ao grau de visibilização das estruturas estudadas e quanto à presença ou ausência de alterações nas vias biliares. Os resultados da CPRM foram comparados, nos casos de CPRM negativa, à evolução clínico-laboratorial por pelo menos 3 meses e, nos casos de CPRM alterada, aos achados de colangiopancreatografia retrógrada endoscópica (CPRE) e cirurgia, quando indicados. RESULTADOS: A visibilização das vias biliares intra-hepáticas foi considerada boa ou excelente em 78,6 por cento e 82,1 por cento dos exames pelos dois observadores. A visibilização da via biliar extra-hepática do doador e do receptor, bem como da anastomose biliar, foi considerada boa ou excelente em 100 por cento dos casos por ambos os observadores. Foram detectadas seis complicações biliares (21,4 por cento dos casos), todas elas estenoses anastomóticas. A concordância intra e intra-observador foi substancial ou quase perfeita (índices de kappa- k de 0,611 a 0,804) para a visualização das estruturas estudadas e quase perfeita (k de 0,900 a 1,000) para a detecção das complicações biliares. A CPRM apresentou sensibilidade de 100 por cento, especificidade de 95,45 por cento, valor preditivo positivo de 85,7 por cento e valor preditivo negativo de 100 por cento para a detecção de complicações biliares. CONCLUSÕES: A colangiopancreatografia por ressonância magnética (CPRM) é um exame acurado para a detecção de complicações biliares em pacientes submetidos a transplantes hepáticos ortotópicos por CPRM. Este exame configura-se como um método eficiente ...
