Quality of death in patients in advanced chronic liver disease and cancer patients managed by gastroenterologists in Portugal: are we doing it right?

INTRODUCTION: The incidence of chronic progressive diseases is rising and investment on quality of death and dying is of utmost importance to minimize physical and emotional suffering. There is still a gap in palliative care (PC) between patients with cancer and those with advanced chronic liver disease (ACLD). Our objectives were to characterize clinical attitudes and therapeutic interventions and to evaluate the differences in end-of-life care between inpatients with cancer and ACLD under gastroenterology care. METHODS: Retrospective cohort study, including patients with cancer or ACLD who died in a Gastroenterology department between 2012 and 2021. Demographic characteristics, clinical and endoscopic procedures and symptom control were compared between the groups. RESULTS: From 150 patients, 118 (78.7%) died with cancer and 32 (21.3%) died from ACLD without concomitant hepatocellular carcinoma. ACLD patients were more frequently male ( P  = 0.001) and younger ( P  = 0.001) than patients with cancer. Median time of hospitalization in the last month of life was 16 days for both groups. Discussion of prognosis with the patient was more frequent for cancer patients (35.6% versus 3.2%, P  < 0.001). Referral to PC occurred in 18.8% and 61% of the patients with ACLD and cancer respectively ( P  < 0.001). Endoscopic procedures were performed in half of the patients and were more likely to be unsuccessful in those with cancer. CONCLUSION: Clinical decisions were different between groups in terms of PC access and discussion of prognostic with the patient. It is urgent to define and implement metrics of quality of death and dying to prevent potentially inappropriate treatment.

Narrow Band Imaging versus White Light for the Detection of Sessile Serrated Colorectal Lesions: A Randomized Clinical Trial.

Background: Colorectal cancer (CRC) is a leading cause of cancer. The detection of pre-malignant lesions by colonoscopy is associated with reduced CRC incidence and mortality. Narrow band imaging has shown promising but conflicting results for the detection of serrated lesions. Methods: We performed a randomized clinical trial to compare the mean detection of serrated lesions and hyperplastic polyps ≥10 mm with NBI or high-definition white light (HD-WL) withdrawal. We also compared all sessile serrated lesions (SSLs), adenoma, and polyp prevalence and rates. Results: Overall, 782 patients were randomized (WL group 392 patients; NBI group 390 patients). The average number of serrated lesions and hyperplastic polyps ≥10 mm detected per colonoscopy (primary endpoint) was similar between the HD-WL and NBI group (0.118 vs. 0.156, p = 0.44). Likewise, the adenoma detection rate (55.2% vs. 53.2%, p = 0.58) and SSL detection rate (6.8% vs. 7.5%, p = 0.502) were not different between the two study groups. Withdrawal time was higher in the NBI group (10.88 vs. 9.47 min, p = 0.004), with a statistically nonsignificant higher total procedure time (20.97 vs. 19.30 min, p = 0.052). Conclusions: The routine utilization of narrow band imaging does not improve the detection of serrated class lesions or any pre-malignant lesion and increases the withdrawal time.

Introdução: O cancro do cólon e reto é a neoplasia mais frequente considerando os dois géneros. . A deteção de lesões pré-malignas por colonoscopia está associada a uma redução da incidência e da mortalidade. Estudos sobre a utilização da luz de banda estreita (NBI) na deteção de lesões serreadas tiveram resultados promissores, mas heterogéneos. Métodos: Realizámos um ensaio clínico randomizado para comparar o número médio de lesões serreadas e lesões hiperplásicas ≥10 mm com NBI ou luz branca de alta-definição (HD-WL). Como resultados secundários comparámos a prevalência e as taxas de deteção de lesões serreadas sésseis, adenomas e todas as lesões. Resultados: Foram randomizados 782 doentes (392 no grupo HD-WL e 390 no grupo NBI). O número médio de lesões serreadas e hiperplásicas ≥10 mm não apresentou diferença estatisticamente significativa entre dois grupos (0.118 vs. 0.156, p = 0.44). A taxa de deteção de adenomas (55.2% vs. 53.2%, p = 0.58) e a taxa de deteção de lesões serreadas sésseis (6.8% vs. 7.5%, p = 0.502) também não foram diferentes. O tempo de retirada foi maior no grupo NBI (10.88 vs. 9.47 min, p = 0.004) e o tempo total de procedimento teve um ligeiro aumento não atingindo significância estatística (20.97 vs. 19.30 min, p = 0.052). Conclusão: A utilização da luz NBI por rotina não aumenta a deteção de lesões serreadas nem de qualquer lesão pré-maligna e aumenta o tempo de retirada na colonoscopia.

Doomed for carcinomatosis? An unusual presentation of abdominal tuberculosis.

A 35-year old male from Brazil presented with intermittent abdominal pain. Abdominal computed tomography revealed a nodule adjacent to splenic hilum and multiple abdominal nodules, suspicious of carcinomatosis. The patient underwent gastroscopy and endoscopic ultrasound (EUS), that revealed an ill-defined hypoechogenic lesion adjacent to the spleen and two hypoechogenic subepithelial lesions located in the 4th layer of the stomach and duodenal bulb. Biopsies revealed non-necrotizing granulomatous inflammation with multinucleated giant cells. Soon after, a 18cm palpable mass within the rectus abdominis muscle was identified, and the biopsy was positive for Mycobacterium tuberculosis DNA, confirming the diagnosis of disseminated abdominal tuberculosis.

Early intervention with biologic therapy in Crohn´s disease: how early is early?

BACKGROUND: Early biologic therapy within the first 18-24 months after diagnosis is associated with improved clinical outcomes in Crohn's disease [CD]. However, the definition of the best time to initiate biologic therapy remains unclear. We aimed to assess if there is an optimal timing for early biologic therapy initiation. METHODS: This was a multicentre retrospective cohort study including newly diagnosed CD patients who started anti-tumour necrosis factor [TNF] therapy within 24 months from diagnosis. The timing of initiation of biologic therapy was categorised as ≤6, 7-12, 13-18, and 19-24 months. The primary outcome was CD-related complications defined as a composite of progression of Montreal disease behaviour, CD-related hospitalisations, or CD-related intestinal surgeries. Secondary outcomes included clinical, laboratory, endoscopic, and transmural remission. RESULTS: We included 141 patients where 54%, 26%, 11%, and 9% started biologic therapy at ≤6, 7-12, 13-18, and 19-24 months after diagnosis, respectively. A total of 34 patients [24%] reached the primary outcome: 8% had progression of disease behaviour, 15% were hospitalised, and 9% required surgery. There was no difference in the time to a CD-related complication according to the time of initiation of biologic therapy within the first 24 months. Clinical, endoscopic, and transmural remission was achieved in 85%, 50%, and 29%, respectively, but no differences were found according to the time of initiation of biologic therapy. CONCLUSION: Starting anti-TNF therapy within the first 24 months after diagnosis was associated with a low rate of CD-related complications and high rates of clinical and endoscopic remission, although we found no differences with earlier initiation within this window of opportunity.

Validation of the Attitude Scale on Prospective Teachers' Perceptions of the Consequences on Their Psychological State: Well-Being and Cognition.

The aim of this study was to analyse the validated psychometric characteristics of the "Scale of Attitudes towards New Post-Pandemic Scenarios" (SANPS) tool using a short version on Perceptions of Future Teachers towards the New Post-Pandemic Educational Scenarios; describe the attitudes of future teachers towards motivation, collaboration, and emerging active pedagogies; and determine the internal consistency and reliability of the tool. The design structure of the instrument consists of the following three latent factors, which were obtained through an exploratory factor analysis (EFA): empowerment/motivation, autonomy/situated learning and emerging digital pedagogies. The questionnaire was administered to a sample of 966 participants. In the confirmatory factor analysis (CFA), a previous hypothesis was established regarding the relationship of the factors and their number and nature, specifying the number of factors and the way in which the variables are related to each other. The 66.53% of total variance was explained. The reliability, calculated with Cronbach's alpha, reached a global value of over 0.90 (α = 0.94). This valid and reliable questionnaire, which incorporates a dimension that measures the transfer of learning in hybrid and multimodal models of digital ecosystems in Higher Education, can be applied in the evaluation of online education processes.

Groove Pancreatitis: Clinical Cases and Review of the Literature.

Introduction: Groove pancreatitis (GP) is a type of chronic segmental pancreatitis that affects the pancreatoduodenal groove area, and it is often misdiagnosed. Outflow obstruction of the minor papilla associated with alcohol consumption seems to be the main pathophysiological mechanism, and it affects mainly middle-aged males. Symptoms include nausea and postprandial vomiting from gastric outlet obstruction, weight loss, and abdominal pain. Despite modern advances, such as radiological and endoscopic methods, distinction between GP and pancreatic cancer remains a challenge, and histological examination is sometimes necessary. When a diagnosis can be obtained without a surgical specimen, management can be conservative in the absence of acute or chronic complications. Case Presentation: The authors present 2 clinical cases which portray the diagnostic workup and management decisions of this entity. Discussion/Conclusion: GP is a clinical entity, offering diagnostic and therapeutic challenges. Imaging exams are crucial in the diagnosis and follow-up, but surgery may be necessary in a significant number of cases due to the incapacity to rule out malignancy.

Introdução: A pancreatite da goteira (PG) constitui uma forma de pancreatite crónica segmentar, que afeta a área da goteira pancreatoduodenal, sendo frequentemente subdiagnosticada. O mecanismo fisiopatológico principal parece ser a obstrução ao fluxo da papila minor relacionada com o consumo de álcool. Esta patologia ocorre mais frequentemente em homens entre a 4a e 5a décadas de vida. A maioria dos doentes apresenta sintomas como náuseas e vómitos pós-prandiais, perda ponderal e dor abdominal. Apesar do desenvolvimento atual dos métodos radiológicos e endoscópicos, a distinção entre PG e neoplasia pancreática constitui um desafio diagnóstico e a avaliação histológica pode ser necessária. Se for possível obter o diagnóstico sem intervenção cirúrgica, o tratamento pode ser conservador na ausência de complicações agudas e crónicas. Apresentação do caso: Apresentamos 2 casos clínicos que demonstram a abordagem diagnóstica e a gestão de decisões terapêuticas nesta entidade. Discussão/Conclusão: A PG é uma entidade clínica que oferece com diagnóstico e terapêutica desafiantes. Apesar da importância crucial dos exames imagiológicos no diagnóstico e seguimento, a incapacidade de excluir um processo maligno torna necessária a intervenção cirúrgica numa parte significativa dos casos.

Clinical Nutrition in Portuguese Gastroenterology Departments: A Multicentric Study.

BACKGROUND: Hospital nutrition is a major public health problem, as up to 50% of hospitalized patients suffer from undernutrition. Adequate nutritional support (NS) decreases morbidity/mortality, shortens the length of stay, and reduces costs. We aimed to evaluate the engagement of Portuguese gastroenterology departments in NS, especially in artificial nutrition (AN). METHODS: Cross-sectional multicentric study, using an online survey sent to 31 Portuguese gastroenterology departments. RESULTS: Nine centers were involved, and all departments were engaged in NS activities. The most performed nutrition technique was endoscopic gastrostomy and not all departments had the expertise to perform all nutrition procedures, namely, endoscopic jejunostomy. Two departments had an AN outpatient clinic. Five centers were involved in hospital nutrition committees. Only four performed systematic nutritional evaluation of every patient on admission. Two departments developed research in the nutrition field. An increase staff and nutrition training were pointed out as suggestions to improve NS. CONCLUSIONS: This study outlines a broad picture of NS/AN in Portuguese gastroenterology departments. Medical nutritional training and increasing nutrition teams' staff may contribute to developing NS/AN. Multidisciplinary management of nutrition-related disorders is of utmost importance, and gastroenterologists are expected to be at the core of hospital nutrition.

Aggressive Colorectal Cancer in an Inflammatory Bowel Disease Patient following Treatment with Vedolizumab: A Case Report.

Introduction: The increased risk of bowel cancer in patients with inflammatory bowel disease can be related with the extent, duration and severity of inflammation or with the cancer immune surveillance interference of immunosuppressive drugs used in inflammatory bowel disease treatment. Therefore, the risk-benefit ratio associated with long-term therapeutic strategies should be based on the patient's age, sex, comorbidities and disease phenotype. Case Report: We present the case of a 76-year-old man with a history of melanoma stage Clark III and steroid-dependent left-sided colitis, refractory to mesalamine and thiopurines, with a diagnosis of a multifocal colorectal adenocarcinoma shortly after clinical and endoscopic remission 1 year after starting vedolizumab. Discussion: Vedolizumab is a gut-selective monoclonal anti-α4ß7-integrin antibody that inhibits lymphocyte migration into the gastrointestinal submucosa. Its effectiveness for induction and maintenance of remission and its favorable safety profile make it an alternative in patients with chronic refractory colitis and contraindications to anti-TNF-α. However, there is the hypothesis that, by reducing the migration of activated leukocytes to the gastrointestinal tract, it may also reduce immunosurveillance, increasing the colorectal malignancy risk in the long term. More studies are necessary to address this issue.

Introdução: O aumento do risco de neoplasias intestinais em doentes com doença inflamatória intestinal correlacionase com a extensão, duração e gravidade de inflamação assim como com o potencial efeito na vigilância imunitária associado aos fármacos imunossupressores utilizados no seu tratamento. Por isso, a avaliação do risco-benefício da utilização de estratégias terapêuticas a longo prazo deve basear-se no género, idade, comorbilidades e fenótipo da doença. Caso clínico: Os autores apresentam o caso de um homem de 76 anos com história pregressa de melanoma maligno estadio Clark III e colite ulcerosa esquerda cortico-dependente e refratária à terapêutica convencional, com o diagnóstico de um adenocarcinoma colo-rectal um ano após ter iniciado terapêutica com vedolizumab e ter atingido remissão clínica e endoscópica. Discussão: O vedolizumab é um anticorpo anti-integrina α4ß7 que inibe a migração dos linfócitos para a submucosa gastrointestinal. A sua eficácia na indução e manutenção da remissão e o seu perfil de segurança tornam-no uma boa alternativa em doentes com doença refratária e contraindicações para anti-TNF-α. Contudo, ao diminuir a migração dos leucócitos para o trato gastrointestinal, poderá reduzir a imunovigilância, aumentando o risco de neoplasia colo-rectal. No entanto, este é ainda um conceito teórico, sendo necessários mais estudos que o comprovem.

Participation in clinical trials increases the detection of pre-malignant lesions during colonoscopy

Background: colorectal adenoma detection has been associated with the effectiveness of cancer prevention. Clinical trials have been designed to determine the role of several interventions to increase the detection of pre-malignant lesions. We hypothesized that colonoscopy in the setting of clinical trials has a higher pre-malignant lesion detection rate.Methods: a cross-sectional study was performed that compared the detection of pre-malignant lesions in 147 randomly sampled non-research colonoscopies and 294 from the control group of two prospective trials. Outpatients aged 40-79 years, with no personal history of colorectal cancer (CRC) were included.Results: baseline characteristics were similar between the two groups. The pre-malignant lesion detection rate in the trial vs control group was 65.6 % vs 44.2 % (OR 2.411; 95 % CI: 1.608-3.614; p < 0.001), the polyp detection rate was 73.8 % vs 59.9 % (OR 1.889; 95 % CI: 1.242-2.876; p = 0.003), the adenoma detection rate was 62.6 % vs 44.2 % (OR 2.110; 95 % CI: 1.411-3.155; p < 0.001) and the sessile serrated lesion detection rate was 17 % vs 4.1 % (OR 4.816; 95 % CI: 2.014-11.515; p < 0.001). The mean number of pre-malignant and sessile serrated lesions was 1.70 vs 1.06 (p = 0.002) and 0.32 vs 0.06 (p = 0.001) lesions per colonoscopy, respectively. There was no significant change in any of the study outcomes according to the multivariate analysis with each single potential confounder.Conclusions: patients involved in colonoscopy trials may benefit from higher quality examinations, as shown by the higher detection rates. Institutions should consider supporting clinical research in colonoscopy as a simple means to improve colonoscopy quality and colorectal cancer prevention. (AU)

Secondary Sclerosing Cholangitis in a Critically Ill Patient with Severe SARS-CoV-2 Infection: A Possibly Emergent Entity during the Current Global Pandemic.

A 46-year-old woman without previous history of hepatobiliary disease was admitted to the intensive care unit due to SARS-CoV-2 infection. Admission blood tests revealed impending hyperinflammation in the context of systemic inflammatory response syndrome. She required 12 days of mechanical ventilation and vasopressor support. After admission, liver function tests became deranged in a cholestatic pattern and continued to worsen despite overall clinical improvement. Magnetic resonance cholangiopancreatography revealed liver abscesses, intrahepatic bile duct dilation with multiple strictures and some linear repletion defects at the bifurcation of the common hepatic duct. During endoscopic retrograde cholangiopancreatography, biliary casts were retrieved confirming the diagnosis of secondary sclerosing cholangitis in the critically ill patient triggered by a severe SARS-CoV-2 infection. Other causes of cholestasis and secondary sclerosing cholangitis were properly excluded. We present an illustrative case and discuss the current literature, focusing on SARS-CoV-2 infection contribution to the development of this potentially underdiagnosed and severe condition.

Uma mulher de 46 anos sem antecedentes de patologia hepatobiliar foi admitida na unidade de cuidados intensivos no contexto de infeção por SARS-CoV-2. Apresentava alterações analíticas interpretadas no contexto de síndrome de resposta inflamatória sistémica. Houve necessidade de suporte vasopressor e ventilação mecânica invasiva durante 12 dias. Após a admissão, verificou-se uma alteração das provas hepáticas com padrão colestático, com agravamento contínuo apesar da melhoria do quadro infecioso. A colangiografia por ressonância magnética revelou a presença de abcessos hepáticos, dilatação das vias biliares intrahepáticas com múltiplas estenoses e com alguns defeitos de repleção lineares na bifurcação do ducto hepático comum. Na colangiopancreatografia endoscópica retrógrada foram removidos cilindros bilares da via biliar, confirmando o diagnóstico de colangite esclerosante secundária associada aos cuidados intensivos, no contexto de uma infeção grave por SARS-CoV-2. Foram excluídas outras causas de colestase e colangite esclerosante secundária de forma exaustiva. Apresentamos um caso clínico ilustrativo com respetiva iconografia e revisão da literatura, com especial enfoque na contribuição da infeção por SARS-CoV-2 no desenvolvimento desta entidade clínica, potencialmente grave e subdiagnosticada.

There was no significant change in any of the study outcomes according to the multivariate analysis with each single potential confounder. CONCLUSIONS: patients involved in colonoscopy trials may benefit from higher quality examinations, as shown by the higher detection rates. Institutions should consider supporting clinical research in colonoscopy as a simple means to improve colonoscopy quality and colorectal cancer prevention.

Inflammatory Bowel Disease Patients' Perspectives during COVID-19 Pandemic: Results from a Portuguese Survey.

INTRODUCTION: Patients with inflammatory bowel disease (IBD) do not seem to be at increased risk of infection by SARS-CoV-2, but there is a concern whether immunosuppressive therapy may be associated with more severe disease. Several clinical practice recommendations have been published to help guide IBD care during the COVID-19 pandemic. Nonetheless, few studies have addressed patients' perspectives and fears. We aimed to evaluate Portuguese IBD patients' perspectives on the clinical management of their disease during the SARS-CoV-2 pandemic as well as the impact on their professional life. METHODS: An anonymous electronic survey was created using REDCap and was distributed by the Portuguese Association of Inflammatory Bowel Disease (APDI) between May and August 2020. Patients' perspectives on immunosuppressive therapy, disease management, interaction with gastroenterology departments, and the impact of the pandemic in their professional life were assessed. Patients' proposals to improve medical care were also evaluated. Descriptive analysis and logistic regression were performed. RESULTS: A total of 137 participants answered the survey (79.6% females, mean age 41.7 ± 12.1 years). Although having IBD and receiving treatment with immunosuppressors (thiopurines, steroids, or biologics) were considered promotors of anxiety, most patients (85.4%) agreed that disease remission was a priority and only a minority of patients interrupted their treatment during the pandemic. In multivariate analysis, active disease, biologic treatment, and use of corticosteroids in the last 3 months were perceived by the patients as high-risk features for increased risk of SARS-Cov-2 infection and more severe disease. Fifty-nine patients (44%) believed that their follow-up was influenced by the pandemic and only 58.8% felt that they had the opportunity to discuss their therapeutic options with their doctor. Sixty-three patients (46.0%) were working from home during the pandemic, although this decision was related to IBD and immunosuppressive therapy in only 36.5 and 39.7% of the cases, respectively. Areas where care could have been improved during the pandemic were identified by patients, namely enhancement of the communication with IBD professionals, conciliation of telemedicine with face-to-face appointments, and facilitation of the interaction between patients and employers. CONCLUSION: Most patients agreed that maintaining IBD remission is crucial, and only a minority of the patients stopped their treatment as per their own initiative. IBD status only had a small influence on patients' professional activity during the COVID-19 outbreak, with most changes being related to the pandemic itself.

COVID-19 in Gastroenterology Departments: The Impact of the First Wave.

INTRODUCTION: Coronavirus disease 2019 (COVID-19) is a global pandemic that has severely affected health care systems around the world. During the emergency state declared in Portugal in the months of March and April 2020, there was a severe reduction in medical activity in order to reduce the pressure on health systems. This study aimed to assess the impact of COVID-19 in gastroenterology departments across Portugal and the strategies developed to overcome this challenge. METHODS: This was a cross-sectional study based on an online survey. A detailed questionnaire concerning different aspects of gastroenterology department activity was sent via e-mail to the heads of gastroenterology departments of Portuguese District Hospitals (Núcleo de Gastroenterologia dos Hospitais Distritais). Two periods were assessed, i.e., the emergency state and the recovery period between May and September. The responses were collected between September and October 2020. RESULTS: A total of 21 hospitals were enrolled (80.8% response rate). Twenty-eight percent of the responders reported healthcare professionals from their unit infected with COVID-19. At least 1 member (mostly fellows) of the department was deployed to another workplace in 66.7% of the hospitals. During the emergency state, 47.6% of the hospitals only performed urgent/emergent endoscopic procedures. In 38.5% of the hospitals the need to ration personal protective equipment led to the suspension of endoscopic training. Regarding the recovery period, nonurgent procedures were restarted in almost all of the centers. The same was reported for the colorectal cancer screening program. Remarkably, 81% of the responders confirmed that they had postponed procedures at patients' request for "fear of getting infected." Remote consultation was maintained in 81% of the hospitals. Globally, the fellows had resumed their training. DISCUSSION/CONCLUSION: This study provides a snapshot of the impact and consequences of the first wave of the COVID-19 pandemic across Portuguese hospitals. It is important to understand how the gastroenterology world dealt with the first impact of COVID-19 and what strategies were implemented in order to better prepare for what might follow.

INTRODUÇÃO: A doença por coronavirus 19 (COVID-19) é uma pandemia global que afetou gravemente os serviços de saúde em todo o mundo. Durante o estado de emergência declarado em Portugal nos meses de Março e Abril de 2020, verificou-se uma redução importante na atividade médica. Este estudo teve como objetivo avaliar o impacto da COVID-19 nos Serviços de Gastroenterologia portugueses e as estratégias implementadas para fazer face a este desafio. MÉTODOS: Tratou-se de um estudo transversal baseado num inquérito online. Um questionário pormenorizado acerca de diferentes aspetos da atividade dum Serviço de Gastroenterologia foi enviado por email para os Diretores de Serviço de Gastroenterologia dos Hospitais Distritais. Foram avaliados dois períodos: o estado de emergência e o período de recuperação entre maio e setembro. Foram registadas as respostas entre setembro e outubro 2020. RESULTADOS: Responderam 21 Hospitais (taxa de resposta: 80,8%). Vinte e oito porcento dos inquiridos tiveram profissionais da sua unidade infectados com COVID-19. Pelo menos um elemento foi mobilizado para outro local de trabalho em 66,7% dos hospitais, maioritariamente internos de formação específica de Gastroenterologia. Durante o estado de emergência, 47,6% dos Hospitais só realizaram endoscopias urgentes/emergentes. Em 38,5%, a necessidade de racionamento de equipamento de proteção individual levou à suspensão do treino em endoscopia. Relativamente ao período de recuperação, os procedimientos não urgentes foram retomados na maioria dos centros. O mesmo se verificou para o programa de rastreio do cancro colorectal. Salienta-se que 81% dos inquiridos confirmaram que adiaram exames a pedido dos doentes por "medo de ficarem infetados". Mantiveram-se consultas nãopresenciais em 81% dos Hospitais. De modo geral, as atividades de formação dos internos foram progressivamente retomadas. DISCUSSÃO/CONCLUSÃO: Este estudo oferece o retrato do impacto e consequências da primeira vaga da pandemia nos Hospitais portugueses. É importante compreender como os Serviços de Gastrenterologia nacionais lidaram com o primeiro impacto da COVID-19 e que estratégias foram implementadas de forma a melhor preparar o que se segue.

Preoperative enteral nutrition in adults with complicated Crohn's disease: Effect on disease outcomes and gut microbiota.

OBJECTIVES: The use of exclusive enteral nutrition (EEN) in patients with Crohn's disease (CD) before surgical resection can reduce disease activity and improve nutritional status. The mechanism of EEN action is unclear, but it might involve modulation of the intestinal microbiota. The aim of this study was to evaluate the effects (namely changes in gut microbiota) of preoperative EEN in adults with complicated CD referred to surgery. METHODS: This was a prospective study of adult patients with CD referred to surgery. Patients with body mass index <18.5 kg/m2, weight loss >10 %, serum albumin <3 g/dL, or a combination of some or all three, received EEN for ≥2 wk. The effects of EEN on clinical (Harvey-Bradshaw Index [HBI]) and laboratory markers (C-reactive protein [CRP], serum albumin, and fecal calprotectin) and fecal microbiota were analyzed after EEN (before surgery) and 6 mo later. We used 16 S rRNA gene sequencing to determine changes in the fecal microbiota. RESULTS: Fifteen patients were included, of whom 60% were men with a mean age of 45.4 ± 19.1 y. Of those, 10 received EEN. The median duration of preoperative EEN was 41.5 d (15-70 d). During EEN, there was a significant reduction in mean HBI (8.7 ± 1.9 versus 4.1 ± 2.4; P = 0.001) and CRP (11.7 ± 10.3 versus 0.8 ± 0.8 mg/dL; P = 0.008) and an increase in serum albumin (3.1 ± 0.6 versus 4 ± 0.6 g/dL; P = 0.022). Two patients did not require surgery after EEN. The overall microbial composition changed after EEN (Permutational analysis of variance test, P = 0.046) and there was a significant reduction in α diversity (8 ± 2.3 versus 5.2 ± 1.5; P = 0.023). EEN significantly changed the relative abundance of 11 taxonomic operational units (OTUs). At the family level, we found this was mainly due to the decrease in the Enterobacteriaceae family (7 OTUs). Six months after surgery, α diversity was not different from that before or after EEN; at this time point 6 OTUs were significantly different, mainly due to the decrease of Clostridiales order (3 OTUs). The incidence of postoperative complications and hospital length of stay were similar in EEN and immediate surgery groups, as well as clinical and endoscopic recurrence rates 6 mo after surgery. CONCLUSIONS: Preoperative EEN improved disease activity and nutritional status in patients with CD referred to surgery. Despite being malnourished, patients given EEN did not have increased postoperative complications compared with well-nourished patients. During EEN, overall microbiota composition changed and α diversity decreased. EEN did not influence postoperative recurrence and gut microbiota 6 mo after surgery.

Adenoma Detection Rate: I Will Show You Mine if You Show Me Yours.

BACKGROUND: Colorectal cancer (CRC) is the first cause of cancer-related mortality in Portugal. CRC screening reduces disease-specific mortality. Colonoscopy is currently the preferred method for screening as it may contribute to the reduction of CRC incidence. This beneficial effect is strongly associated with the adenoma detection rate (ADR). AIM: Our aim was to evaluate the quality of colonoscopy at our unit by measuring the currently accepted quality parameters and publish them as benchmarking indicators. METHODS: From 5,860 colonoscopies, 654 screening procedures (with and without previous fecal occult blood testing) were analyzed. RESULTS: The mean age of the patients was 66.4 ± 7.8 years, and the gender distribution was 1:1. The overall ADR was 36% (95% confidence interval [CI] 32-39), the mean number of adenomas per colonoscopy was 0.66 (95% CI 0.56-0.77), and the sessile serrate lesion detection rate was 1% (95% CI 0-2). The bowel preparation was rated as adequate in 496 (76%) patients. The adjusted cecal intubation rate (CIR) was 93.7% (95% CI 91.7-95.8). Most colonoscopies were performed under monitored anesthesia care (53%), and 35% were unsedated. The use of sedation (propofol or midazolam based) was associated with a higher CIR with an odds ratio of 3.60 (95% CI 2.02-6.40, p < 0.001). CONCLUSION: Our data show an above-standard ADR. The frequency of poor bowel preparation and the low sessile serrated lesion detection rate were acknowledged, and actions were implemented to improve both indicators. Quality auditing in colonoscopy should be compulsory, and while many units may do so internally, this is the first national report from a high-throughput endoscopy unit.

Trends in net survival from stomach cancer in six European Latin countries: results from the SUDCAN population-based study.

Gastric cancers are a clinical challenge. The aim of the SUDCAN collaborative study was to compare the net survival from gastric cancer between six European Latin countries (Belgium, France, Italy, Portugal, Spain and Switzerland) and explore the trends in net survival and in the dynamics of the excess mortality rates (EMRs) up to 5 years after diagnosis. The data were extracted from the EUROCARE-5 database. First, net survival was studied over the period 2000-2004 using the Pohar-Perme estimator. For trend analyses, the study period was specific to each country. The results are reported from 1992 to 2004 in France, Italy, Spain and Switzerland and from 2000 to 2004 in Belgium and Portugal. These trend analyses were carried out using a flexible excess rate modelling strategy. There were little differences between countries in age-standardized net survival for stomach cancer (2000-2004). The 5-year net survival ranged between 26 (Spain) and 32% (Italy). There was a small increase in the age-standardized net survival at 1 year between 1992 and 2004. The increase was also observed in the 5-year net survival, except in France, where the increase was less marked. A slight decrease in the EMR between 1992 and 2004 was limited to the 24 months after diagnosis. In addition, the decrease in the EMR was the same whatever the year of diagnosis. There were minor differences in survival from stomach cancer between European Latin countries. A slight improvement in the 5-year net survival was observed in all countries and the major gain was observed during the 24 months after diagnosis. Development of innovative treatments is needed to improve the prognosis.

Non-anesthesiologist administration of propofol sedation for colonoscopy is safe in low risk patients: results of a noninferiority randomized controlled trial.

BACKGROUND AND STUDY AIMS: Propofol provides the best sedation in colonoscopy. The safety of non-anesthesiologist administration of propofol (NAAP) is still a matter of debate. The aim of the current study was to evaluate sedation safety, colonoscopy quality, and patient satisfaction with NAAP. PATIENTS AND METHODS: The study was a single-blinded, noninferiority, randomized controlled trial comparing NAAP (Group A) with anesthesiologist-administered sedation (Group B) performed at a single academic institution. Patients (18 - 80 years) who underwent colonoscopy and were at low anesthetic risk (American Society of Anesthesiologists class I - II) were included. The primary end point was the incidence of adverse events. Secondary end points were propofol dose, patient satisfaction and pain, colonoscopy quality indicators, and procedure and recovery times. RESULTS: A total of 277 patients were included in the analysis. The incidence of adverse events was 39.3 % in Group A and 39.0 % in Group B (absolute difference - 0.3 %, 95 % confidence interval [CI] - 12.0 % to 11.4 %; P = 0.959). There were no sentinel adverse events. The following interventions (Group A vs. Group B) were necessary: atropine administration (0 % vs. 5.5 %; P = 0.004); airway repositioning (8.7 % vs. 4.7 %; P = 0.196); increased oxygen administration (6.7 % vs. 3.9 %; P = 0.317), and increased fluid rate (2.7 % vs. 0.8 %; P = 0.379). There were no differences in cecal intubation and adenoma detection rates. Recovery times were longer in Group B (58 ±â€Š33 vs. 67 ±â€Š29 minutes; P = 0.032). There were no differences in mean propofol dose, withdrawal time, painless colonoscopy, satisfaction, and amnesia. All but two patients (Group B) were willing to repeat the colonoscopy. CONCLUSIONS: NAAP is equivalent to anesthesiologist-administered sedation in the rate of adverse events in a low risk population. TRIAL REGISTRATION: ClinicalTrials.gov (NCT02067065).

Acute lower gastrointestinal bleeding management in Portugal: a multicentric prospective 1-year survey.

INTRODUCTION: Acute lower gastrointestinal bleeding (ALGIB) is a common event, which consumes considerable human and economic resources. Its incidence is expected to rise in the coming years due to an increasing aging population. PATIENTS AND METHODS: Multicentric prospective analysis of patients was carried out with ALGIB in 13 Portuguese hospitals from April 2008 to May 2009, using a protocol designed by the French Association Nationale des Hépato-Gastroentérologues des Hôpitaux Généraux. Statistical analysis was carried out with SPSS 16.0. RESULTS: In a total of 371 hemorrhagic events in 364 patients (51.4% men, mean age: 72 years), 28.4% patients showed hemodynamic instability and 54.2% were under single/combined medication with antiaggregants/NSAIDs/heparin/anticoagulants; blood transfusion was administered in 34.8% of patients. Sigmoidoscopy was the first endoscopic procedure performed in 61.3% of patients and rectal enema was the first method of bowel preparation in 67.3% of them. Endoscopic hemostasis was performed in 22.2% of all cases with efficacy ranging from 84.6 to 96.2%. Most frequent diagnoses were ischemic colitis (23.7%), diverticulosis (20.8%), and colorectal malignancies (12.4%). Surgery was needed in 8% of patients, and global mortality rate was 2.2%. Risk factors for poor outcome on multivariate analysis were heparin use before bleeding (hazards ratio: 10.6; 95% confidence interval: 0.94-119.48) and in-hospital bleeding (hazards ratio: 5.6; 95% confidence interval: 1.01-19.70). CONCLUSION: ALGIB seems to occur frequently in Portugal with a low mortality rate. Previous heparin use and in-hospital bleeding are associated with worse prognosis. Our management relies on early endoscopic examinations, which are highly available, safe, and accurate. A successful endoscopic therapeutic approach was possible in one fifth of the patients.
