Non-invasive tests for the prediction of post-hepatectomy liver failure in the elderly

Post-hepatectomy liver failure (PHLF) is associated with great morbidity and mortality after resection of hepatocellular carcinoma. Previous studies have underlined that advanced age could be a potential factor influencing post-operative complications and long-term survival. In the past, candidates for resection were based on the Child-Pugh classification, the predictive value of which was rather low. The selection of patients undergoing resection in Western countries is based on the assessment of portal hypertension (PH), which is clinically assessed by measurement of the hepatic venous pressure gradient, an invasive and costly process. Thus, there have been several attempts to identify the best non-invasive test (NIT) to accurately predict PHLF. Most biochemical NITs for the prediction of PHLF are focused on evaluation of underlying liver cirrhosis and PH. Amongst them, FIB-4, which also includes the patient’s age, seems to have more robust supporting results. In Europe and the USA., the most tested and reliable NIT for predicting PHLF is the evaluation of liver stiffness measurement, which is also influenced by age. Imaging parameters are promising tools which are used only in specialized centers however, and when available. Liver volume parameters, as well as contrast-enhanced data, demonstrate good accuracy in predicting PHLF. In this scenario, the evaluation of sarcopenia and bone mineral density through contextual imaging allows the delineation of PHLF in at-risk elderly patients. Further studies focused on parameters for the evaluation of PHLF in elderly patients are needed

Patterns of injury and violence in Yaoundé Cameroon: an analysis of hospital data.

BackgroundInjuries are quickly becoming a leading cause of death globally, disproportionately affecting sub-Saharan Africa, where reports on the epidemiology of injuries are extremely limited. Reports on the patterns and frequency of injuries are available from Cameroon are also scarce. This study explores the patterns of trauma seen at the emergency ward of the busiest trauma center in Cameroon's capital city.Materials and methodsAdministrative records from January 1, 2007, through December 31, 2007, were retrospectively reviewed; information on age, gender, mechanism of injury, and outcome was abstracted for all trauma patients presenting to the emergency ward. Univariate analysis was performed to assess patterns of injuries in terms of mechanism, date, age, and gender. Bivariate analysis was used to explore potential relationships between demographic variables and mechanism of injury.ResultsA total of 6,234 injured people were seen at the Central Hospital of Yaoundé's emergency ward during the year 2007. Males comprised 71% of those injured, and the mean age of injured patients was 29 years (SD = 14.9). Nearly 60% of the injuries were due to road traffic accidents, 46% of which involved a pedestrian. Intentional injuries were the second most common mechanism of injury (22.5%), 55% of which involved unarmed assault. Patients injured in falls were more likely to be admitted to the hospital (p < 0.001), whereas patients suffering intentional injuries and bites were less likely to be hospitalized (p < 0.001). Males were significantly more likely to be admitted than females (p < 0.001)DiscussionPatterns in terms of age, gender, and mechanism of injury are similar to reports from other countries from the same geographic region, but the magnitude of cases reported is high for a single institution in an African city the size of Yaoundé. As the burden of disease is predicted to increase dramatically in sub-Saharan Africa, immediate efforts in prevention and treatment in Cameroon are strongly warranted

Nódulo tireoidiano e câncer diferenciado de tireoide: atualização do consenso brasileiro

Thyroid nodules are frequent findings, especially when sensitive imaging methods are used. Although thyroid cancer is relatively rare, its incidence is increasing, particularly in terms of small tumors, which have an uncertain clinical relevance. Most patients with differentiated thyroid cancer exhibit satisfactory clinical outcomes when treatment is appropriate, and their mortality rate is similar to that of the overall population. However, relapse occurs in a considerable fraction of these patients, and some patients stop responding to conventional treatment and eventually die from their disease. Therefore, the challenge is how to identify the individuals who require more aggressive disease management while sparing the majority of patients from unnecessary treatments and procedures. We have updated the Brazilian Consensus that was published in 2007, emphasizing the diagnostic and therapeutic advances that the participants, representing several Brazilian university centers, consider most relevant in clinical practice. The formulation of the present guidelines was based on the participants' experience and a review of the relevant literature.Nódulos tireoidianos são muito frequentes, sobretudo quando se empregam métodos sensíveis de imagem. Embora o câncer seja proporcionalmente raro, sua incidência vem aumentando, especialmente de tumores pequenos, cuja evolução clínica é incerta. A maioria dos pacientes com carcinoma diferenciado de tireoide evolui bem quando adequadamente tratada, com índices de mortalidade similares à população geral. Por outro lado, um percentual não desprezível apresenta recidivas e alguns eventualmente não respondem às terapias convencionais, evoluindo para óbito. Assim, o desafio é distinguir os pacientes merecedores de condutas mais agressivas e, ao mesmo tempo e não menos importante, poupar a maioria de tratamentos e procedimentos desnecessários. Atualizamos o Consenso Brasileiro publicado em 2007, ressaltando os avanços diagnósticos e terapêuticos que os participantes, de diferentes Centros Universitários do Brasil, consideram mais relevantes para prática clínica. A elaboração dessas diretrizes foi baseada na experiência dos participantes e revisão da literatura pertinente.Instituto de Ensino e Pesquisa Serviço de EndocrinologiaUniversidade Estadual de Campinas Faculdade de Ciências Médicas Departamento de Clínica MédicaUniversidade Federal do Paraná Serviço de Endocrinologia e MetabologiaUniversidade Federal de São Paulo (UNIFESP) Escola Paulista de Medicina Departamento de MedicinaUniversidade de São Paulo Faculdade de Medicina de Ribeirão Preto Departamento de Clínica MédicaUniversidade Federal do Rio Grande do Sul Hospital de Clínicas de Porto Alegre Serviço de EndocrinologiaUniversidade Federal do Rio de Janeiro Faculdade de Medicina Hospital Universitário Clementino Fraga FilhoUNIFESP, EPM, Depto. de MedicinaSciEL

What is New in Gastroenterology and Hepatology

Gastroenterology and hepatology represent dynamic fields of study and practice in internal medicine, with numerous innovations manifesting over the last 30 years. What is New in Gastroenterology and Hepatology is a reference which presents updates on the latest advances in the aforementioned subspecialties. The book offers a broad range of topics in a structured, clear and comprehensive fashion. Thirty-three chapters provide knowledge on basic medical research and practical applications in the clinic with information contributed by several members of the Romanian Society of Gastroenterology and Hepatology (a medical society with a history of more than 60 years). The contents feature updates on common and rare disorders of the gastrointestinal tract (esophagus, stomach, intestines), pancreas and the liver, as well as new imaging techniques such as video capsule endoscopy and contrast enhanced ultrasound (CEUS). Special topics of recent interest such as the value of gut microbiota in medical interventions and the use of ‘omics’ technologies for precision medicine, and telemedicine are also included. What is New in Gastroenterology and Hepatology is an informative reference for all medical researchers and healthcare professionals (gastroenterologists, hepatologists, internal medicine physicians, surgeons, oncologists) who wish to keep themselves up to speed on new advances in these medical subspecialties
