ABSTRACT

OBJECTIVES: Referral for liver transplant (LT) following acute variceal bleeding (AVB) varies widely. We aimed to characterize and assess its impact on clinical outcomes. METHODS: Observational retrospective cohort including cirrhosis patients with AVB from 3 hospitals in Lisbon, Portugal, from 2018 to 2019. Primary exposure was referral for LT and primary endpoint was all-cause mortality within 2 years of index hospital admission. RESULTS: Among 143 patients, median (IQR) age was 59 (52-72) years and 90 (62.9%) were males. Median (IQR) MELDNa scores on hospital admission and discharge were 15 (11-21) and 13 (10-16), respectively. Overall, 30 (21.0%) patients were assessed for LT, 13 (9.1%) prior to and 17 (11.9%) within 2 years of hospital admission. Overall, 58 (40.6%) patients had at least one potential contra-indication for transplant. LT was performed in 3 (2.1%) patients (among 5 listed). Overall, 34 (23.8%) and 62 (43.4%) patients died at 6 weeks and 2 years post hospital admission, respectively. Following adjustment for confounders, referral for LT was associated with lower 2-year mortality (aHR (95% CI) = 0.20 (0.05-0.85)). CONCLUSION: In a multicenter cohort of cirrhosis patients with AVB, less than a quarter underwent formal LT evaluation. Improved referral for LT following AVB may benefit cirrhosis patients' longer-term mortality.

ABSTRACT

Background: Listing patients with alcohol-associated liver disease (ALD) for liver transplant (LT) remains challenging especially due to the risk of alcohol resumption post-LT. We aimed to evaluate post-LT alcohol consumption at a Portuguese transplant center. Methods: We conducted a cross-sectional study including LT recipients from 2019 at Curry Cabral Hospital, Lisbon, Portugal. A pretested survey and a validated Portuguese translation of the Alcohol Use Disorder Identification Test (AUDIT) were applied via a telephone call. Alcohol consumption was defined by patients' self-reports or a positive AUDIT. Results: In 2019, 122 patients underwent LT, and 99 patients answered the survey (June 2021). The mean (SD) age was 57 (10) years, 70 patients (70.7%) were males, and 49 (49.5%) underwent ALD-related LT. During a median (IQR) follow-up of 24 (20-26) months post-index LT, 22 (22.2%) recipients consumed any amount of alcohol: 14 had a drink monthly or less and 8 drank 2-4 times/month. On drinking days, 18 patients usually consumed 1-2 drinks and the remainder no more than 3-4 drinks. One patient reported having drunk ≥6 drinks on one occasion. All post-LT drinking recipients were considered low risk (score <8) as per the AUDIT score (median [IQR] of 1 [1-2]). No patient reported alcohol-related problems, whether self-inflicted or toward others. Drinking recipients were younger (53 vs. 59 years, p = 0.020), had more non-ALD-related LT (72.7 vs. 44.2%, p = 0.018) and active smoking (31.8 vs. 10.4%, p = 0.037) than abstinent ones. Conclusion: In our cohort, about a quarter of LT recipients consumed alcohol early posttransplant, all with a low-risk pattern according to the AUDIT score.


Introdução: Incluir doentes com doença hepática associada ao álcool (DHA) em lista ativa de transplante hepático (TH) é desafiante, especialmente pelo risco de recidiva de consumo de álcool pós-TH. O objetivo foi avaliar o consumo de álcool pós-TH num centro de transplantação português. Métodos: Realizamos um estudo transversal incluindo doentes submetidos a TH em 2019 no Hospital Curry Cabral, Lisboa, Portugal. Foi realizado um questionário previamente testado e uma tradução validada para o português do Alcohol Use Disorder Identification Test (AUDIT), através de uma chamada telefónica. O consumo de álcool foi definido pelo autorrelato do doente ou por um AUDIT positivo. Resultados: Durante 2019, 122 doentes foram submetidos a TH e 99 responderam ao questionário (junho de 2021). A idade média (SD) foi de 57 (10) anos, 70 doentes (70,7%) eram do sexo masculino e 49 (49,5%) foram submetidos a TH relacionado com DHA. Com uma mediana (IQR) de follow-up de 24 (20­26) meses após o TH-índex, 22 (22,2%) doentes admitiram algum consumo de álcool: 14 beberam mensalmente ou menos e oito beberam 2­4 vezes/mês. Nos dias em que bebiam, 18 consumiam normalmente 1­2 bebidas e os restantes não mais do que 3­4 bebidas. Um doente reportou o consumo de ≥6 bebidas em uma ocasião. Todos os doentes transplantados com consumo alcoólico pós-TH foram considerados de baixo risco (pontuação >8) de acordo com o AUDIT (mediana [IQR] de 1 [1­2]). Nenhum doente reportou problemas relacionados com o álcool, tanto autoinfligido como a terceiros. Os indivíduos transplantados com consumo alcoólico eram mais jovens (53 vs. 59 anos, p = 0,020), o motivo de TH era mais frequentemente não relacionado com DHA (72,7 vs. 44,2%, p = 0,018) e apresentavam mais tabagismo ativo (31,8 vs. 10,4%, p = 0,037) quando comparado com os abstinentes. Conclusão: Na nossa coorte, cerca de um quarto dos doentes transplantados hepáticos consumiram álcool no período pós-transplante precoce, todos com um padrão de baixo risco, de acordo com o AUDIT.

ABSTRACT

Background and Aims: The donor risk index (DRI) quantifies donor-related characteristics potentially associated with increased risk of early graft failure. We aimed to assess the impact of the DRI, recipient and perioperative factors on post liver transplant (LT) outcomes. Methods: This was a single-center retrospective cohort study including all adult (≥18 years) patients who underwent LT from 01/2019 to 12/2019 at Curry Cabral Hospital, Lisbon, Portugal. Primary endpoint was 1-year graft failure post LT. Associations were studied with logistic regression. Results: A total of 131 cadaveric donor LT procedures were performed in 116 recipients. Recipients' median (IQR) age was 57 (47-64) years and 101/131 (77.1%) were males. Cirrhosis was the underlying etiology in 95/131 (81.2%) transplants. Based on 8 predefined donors' characteristics, median (IQR) DRI was 1.96 (1.67-2.16). Following adjustment for MELDNa score pre LT and SOFA score (adjusted odds ratio [aOR], 95% confidence interval [CI] = 0.91 [0.56-1.47]) or lactate (aOR [95% CI] = 2.76 [0.71-10.7]) upon intensive care unit (ICU) admission post LT, DRI was not associated with 1-year graft failure. However, higher SOFA score (aOR [95% CI] = 1.20 [1.05-1.37]) or lactate (aOR [95% CI] = 1.27 [1.10-1.46]) upon ICU admission post LT were independently associated with higher odds of 1-year graft failure. Conclusions: In a recent cohort of patients who underwent LT, DRI, despite being high, was not associated with 1-year graft failure, but SOFA score or lactate upon ICU admission post LT were.


Introdução: O índice de risco do dador (DRI) quantifica as características relacionadas com o dador potencialmente associadas com risco acrescido de falência precoce do enxerto. Procurou-se avaliar o impacto do DRI e factores relacionados com os receptores e cirurgia nos resultados clínicos após transplante hepático (LT). Materiais e Métodos: Estudo coorte retrospectivo de centro único incluindo todos os doentes adultos (≥18 anos) que receberam LT entre 01/2019 e 12/2019 no Hospital Curry Cabral, Lisboa, Portugal. O endpoint primário foi a falência do enxerto após um ano do LT. As associações foram estudadas com regressão logística. Resultados: Um total de 131 transplantes de dadores cadavéricos foram realizados em 116 receptores. A idade mediana (IQR) destes foi 57 (47­64) anos e 101/131 (77.1%) eram homens. A cirrose foi a etiologia subjacente em 95/131 (81.2%) transplantes. Com base nas 8 características dos dadores predefinidas, o DRI mediano (IQR) foi 1.96 (1.67­2.16). Após ajuste para o score MELDNa pre LT e o score SOFA (odds ratio ajustado [aOR], intervalo de confiança 95% [CI] = 0.91 [0.56­1.47]) ou o lactato (aOR [95% CI] = 2.76 [0.71­10.7]) após admissão na unidade de cuidados intensivos (ICU) pós LT, o DRI não se associou com a falência do enxerto um ano depois do LT. Contudo, um maior score SOFA (aOR [95% CI] = 1.20 [1.05­1.37]) ou lactato (aOR [95% CI] = 1.27 [1.10­1.46]) após admissão na ICU depois do LT associaram-se independentemente com a falência do enxerto um ano depois do LT. Conclusões: Num coorte recente de doentes submetidos a LT, o DRI, apesar de alto, não se associou com a falência precoce do enxerto precoce. Contudo, o score SOFA ou lactato após admissão na ICU depois do LT associaram-se com a falência precoce do enxerto.

ABSTRACT

BINGO (BAO from Integrated Neutral Gas Observations) is a unique radio telescope designed to map the intensity of neutral hydrogen distribution at cosmological distances, making the first detection of Baryon Acoustic Oscillations (BAO) in the frequency band 980 MHz - 1260 MHz, corresponding to a redshift range 0.127 < z < 0.449. BAO is one of the most powerful probes of cosmological parameters and BINGO was designed to detect the BAO signal to a level that makes it possible to put new constraints on the equation of state of dark energy. The telescope will be built in Paraíba, Brazil and consists of two \thicksim 40m mirrors, a feedhorn array of 50 horns, and no moving parts, working as a drift-scan instrument. It will cover a 15 ^{\circ} ∘ declination strip centered at \sim \delta ∼ δ =-15 ^{\circ} ∘ , mapping \sim ∼ 5400 square degrees in the sky. The BINGO consortium is led by University of São Paulo with co-leadership at National Institute for Space Research and Campina Grande Federal University (Brazil). Telescope subsystems have already been fabricated and tested, and the dish and structure fabrication are expected to start in late 2020, as well as the road and terrain preparation.

ABSTRACT

INTRODUCTION: Recent studies assessed the predictive value of liver transient elastography, combined or not with platelet count, for the presence of esophageal varices in patients with liver cirrhosis, and multiple cutoffs have been proposed. The Baveno VI consensus states that patients with compensated advanced chronic liver disease, liver stiffness <20 kPa, and a platelet count >150,000 have a very low risk of having varices requiring treatment and can avoid screening endoscopy. We aimed to validate this recommendation in a cohort of cirrhotic patients. METHODS: Retrospective analysis of all patients evaluated at the Gastroenterology Department (Centro Hospitalar de Lisboa Central) between September 2009 and October 2015 with a liver stiffness (FibroScan®) compatible with liver cirrhosis as well as upper endoscopy and blood tests within 12 months from elastography. Patients on propranolol ≥80 mg/day or carvedilol ≥12.5 mg/day, as well as those with previous variceal bleeding, variceal endoscopic treatments, or cirrhosis decompensations were excluded. We validated the new Baveno VI recommendation and explored alternative cutoffs. RESULTS: Ninety-seven patients were analyzed, 76.3% (74/97) male, mean age 54.3 ± 11.2 years. Most patients (55.7%) had no varices and 14.4% had varices requiring treatment. Most patients (78.4%) had cirrhosis related to chronic hepatitis C. If the new Baveno VI recommendation had been applied to this cohort, upper endoscopy would have been avoided in 11.3% (11/97) of patients, none of them with esophageal varices requiring treatment: specificity 100%, sensitivity 13.3%, positive predictive value 100%, and negative predictive value 16.3% for absence of varices requiring treatment. If screening endoscopy had been avoided in those patients with liver stiffness <30 kPa and platelet count ≥120,000, endoscopy would have been avoided in 27.8% (27/97) of patients, none of whom with esophageal varices requiring treatment: specificity 100%, sensitivity 32.5%, positive predictive value 100%, and negative predictive value 20% for absence of varices requiring treatment. CONCLUSIONS: The new Baveno VI criteria identified compensated cirrhotic patients without varices requiring treatment in whom screening endoscopy could have been avoided safely. Further studies are needed to confirm these findings and potentially explore more ambitious but still safe cutoffs for those criteria.

ABSTRACT

The continuous delivery of a levodopa/carbidopa gel suspension (Duodopa®) into the small bowel through a jejunal tube inserted via percutaneous endoscopic gastrostomy represents a new treatment method in advanced Parkinson disease. Some severe device-related complications have been described in the last few years. Some of them are associated with phytobezoar formation at the pigtail of the catheter. We present the case of a Parkinson disease patient treated with the Duodopa infusion system complicated by jejunal tube fistulization into the colon. We suggest a possible treatment strategy for this complication, which has not been described in the literature to date.

ABSTRACT

Resumo Atletas de judô geralmente recorrem em períodos prévios às competições ao uso de métodos de perda de peso rápida. Essa prática tem como objetivo o benefício do atleta que competirá em uma categoria de menor peso e buscará recuperar o peso em um curto tempo entre a pesagem e a competição. Contudo, o uso dessa prática sem um acompanhamento profissional pode ser prejudicial à saúde do atleta. Objetivo: Investigar os métodos e as estratégias usados para perda de peso em competidores de judô de nível nacional de diferentes categorias. Métodos: 60 atletas de judô competidores de nível nacional de ambos os sexos de diferentes categorias (juvenil, júnior, sênior e master) responderam a um questionário com perguntas referentes ao uso ou não de métodos de perda de peso e quais são as estratégias de perda de peso frequentemente usadas no período pré-competitivo. Resultado: 80% (juvenil), 69,6% (júnior), 88,9% (sênior) e 100% (master) usam métodos de perda de peso pré-competição, 70% (juvenil), 69,6% (júnior), 77,8% (sênior) e 77,7% (master) relataram ter o seu desempenho prejudicado pelo uso dessas estratégias. Conclusão: Observou-se que uma quantidade bem elevada de atletas de judô, de diferentes categorias de idade, faz uso de métodos ou estratégias de perda de peso rápida. Esse fato demonstrou ter efeito deletério direto sobre o desempenho físico e emocional dos atletas durante as competições.


Abstract Judo athletes often use in previous periods of competitions, methods for rapid weight loss. This purpose of this practice is benefit the athlete, competing in a lower weight category and tries to regain weight in a short space of time between the weigh-in and competition. However, the use of this practice without professional supervision may be harmful to the health of the athlete. Objective: Investigate the methods and strategies used for weight loss in judo competitors at the national level and different categories. Methods: 60 athletes the national levels, male and female, of different ages (juvenile, junior, senior and master) answered a questionnaire regarding the use or not of methods for weight loss and what are the strategies loss weight often used in the pre-competition period. Results: 80% (juvenile), 69.6% (junior), 88.9% (senior) and 100% (master) use methods of weight loss pre-competition, and 70% (juvenile), 69.6% (junior), 77.8% (senior) and 77.7% (master) reported their performance impaired by the use of these strategies. Conclusion: We found that a much higher judo athletes from different age categories, makes use of methods or strategies for rapid weight loss. This fact has shown a direct deleterious effect on the physical and emotional performance of athletes during competitions.


Resumen Los judocas en los períodos anteriores a las competiciones a menudo usan métodos de pérdida de peso rápida. Esta práctica tiene como objetivo beneficiar el hecho de que el judoca compita en una categoría de peso inferior y trate de recuperar el peso en un corto espacio de tiempo entre el pesaje y la competición. Sin embargo, el uso de esta práctica sin supervisión profesional puede ser perjudicial para la salud del deportista. Objetivo: Investigar los métodos y estrategias utilizados para la pérdida de peso en la competición de judo a nivel nacional en distintas categorías. Métodos: 60 competidores de judo a nivel nacional de ambos sexos y distintas categorías (juvenil, júnior, sénior y máster) respondieron a un cuestionario sobre el uso de métodos para bajar de peso o no, y cuáles son las estrategias de pérdida peso utilizadas con frequencia en el período previo a la competición. Resultados: El 80% (juvenil), el 69,6% (júnior), el 88,9% (sénior) y el 100% (máster) utilizan métodos de pérdida de peso antes de la competición, y el 70% (juvenil), el 69,6% (júnior), el 77,8% (sénior) y el 77,7% (máster) comunicaron que sus resultados se vieron afectados por el uso de estas estrategias. Conclusión: Se observó que diversos atletas de distintas categorías de edad utilizaron métodos o estrategias para perder peso rápidamente. Este hecho ha demostrado un efecto directo perjudicial sobre el rendimiento físico y emocional de los atletas durante las competiciones.
