Gastric Ulcer: A Rare Cause of Upper Gastrointestinal Bleeding.

Strongyloidiasis is an infection caused by Gastrointestinal manifestations typically include duodenitis, chronic enterocolitis, and malabsorption, while gastric involvement is very rare. In this case report, the -authors present a case of upper gastrointestinal bleeding caused by a gastric ulcer with a challenging etiological diagnosis. In Portugal, there have been reports in the past century of autochthonous cases of infection suggesting endemic zones, but with the current sanitation infrastructure strongyloidiasis is thought to be rare.

Clube Português do Pâncreas Recommendations for Chronic Pancreatitis: Medical, Endoscopic, and Surgical Treatment (Part II).

Chronic pancreatitis (CP) is a complex disease that should be treated by experienced teams of gastroenterologists, radiologists, surgeons, and nutritionists in a multidisciplinary environment. Medical treatment includes lifestyle modification, nutrition, exocrine and endocrine pancreatic insufficiency correction, and pain management. Up to 60% of patients will ultimately require some type of endoscopic or surgical intervention for treatment.

Clube Português do Pâncreas Recommendations for Chronic Pancreatitis: Etiology, Natural History, and Diagnosis (Part I).

Chronic pancreatitis (CP) is a heterogeneous disease, with different causes and often a long delay between onset and full classic presentation. Clinical presentation depends on the stage of the disease. In earlier stages, recurrent episodes of acute pancreatitis are the major signs dominating clinical presentation.

Non-canonical Wnt signaling regulates junctional mechanocoupling during angiogenic collective cell migration.

Morphogenesis of hierarchical vascular networks depends on the integration of multiple biomechanical signals by endothelial cells, the cells lining the interior of blood vessels. Expansion of vascular networks arises through sprouting angiogenesis, a process involving extensive cell rearrangements and collective cell migration. Yet, the mechanisms controlling angiogenic collective behavior remain poorly understood.

Primary adenocarcinoma arising in esophageal colon interposition for corrosive esophageal injury: a case report and review of the literature.

 Colon interposition for benign strictures is associated with significant perioperative complications that carry high morbidity and mortality. Although rarely reported in the literature, adenocarcinoma can occur as a late complication in an interposed colonic segment. We report a case of a late-stage adenocarcinoma in a colonic interposition performed for benign esophageal stricture.

New Insights About Albumin and Liver Disease.

Decompensated liver cirrhosis has a dismal prognosis, with an overall survival of 2-4 years, which is worse than for many oncological diseases. Albumin is an important tool in the management of patients with cirrhosis, since it decreases for less than half the risk for post-paracentesis cardiocirculatory dysfunction and mortality associated with spontaneous bacterial infection, as well as, it triplicates the response to terlipressin in patients with hepatorenal syndrome. Recently, research on albumin has been a hot topic, with important new insights such as the characterization of the pleiotropic effects of albumin (which surpass its oncotic properties) and the concept of effective albumin concentration.

Lipids, glucose and iron metabolic alterations in chronic hepatitis C after viral eradication - comparison of the new direct-acting antiviral agents with the old regimens.

Background: Hepatitis C virus (HCV) is a unique virus which interacts with cholesterol, iron and insulin metabolism. There is limited data on the effects of direct-acting antiviral agents (DAAs) on metabolic profiles. We aimed at evaluating the behavior of metabolic risk factors of chronically HCV-infected patients after sustained virologic response (SVR), comparing the outcomes with the new DAAs versus the old treatment regimen Peg-interferon ± ribavirin.

Identifying palliative care needs in a Portuguese liver unit.

Background & Aims: Chronic liver disease is a major worldwide cause of morbidity and mortality. Palliative care policies are not clearly established in chronic liver disease. The NECPAL CCOMS-ICO© (NECesidades PALiativas/Palliative Needs) is a tool to identify palliative care needs, including a section for liver disease.

Signet Ring Cell Carcinoma, Ileal Crohn Disease or Both? - A Case of Diagnostic Challenge.

Signet ring cell carcinoma is a rare form of adenocarcinoma that predominantly affects the stomach. Signet ring cell carcinoma originated from the ileum is extremely rare and the prognosis is poor. We present a case of small bowel obstruction with features suggesting Crohn disease of the ileum.

YAP and TAZ regulate adherens junction dynamics and endothelial cell distribution during vascular development.

Formation of blood vessel networks by sprouting angiogenesis is critical for tissue growth, homeostasis and regeneration. How endothelial cells arise in adequate numbers and arrange suitably to shape functional vascular networks is poorly understood. Here we show that YAP/TAZ promote stretch-induced proliferation and rearrangements of endothelial cells whilst preventing bleeding in developing vessels.

Acute pancreatitis in the elderly: a cause for increased concern?

Background: Acute pancreatitis (AP) is an aggressive and potentially fatal clinical condition. Although all age groups are at risk, the elderly may be a group of special concern. We aimed at evaluating clinical outcomes of patients with elderly-onset AP.

Predicting short-term and long-term mortality of hospitalized Portuguese patients with alcoholic hepatitis.

Background: Alcohol abuse can result in a spectrum of liver injury that ranges from mild fatty infiltration to alcoholic hepatitis (AH), cirrhosis, and hepatocellular carcinoma. The present study aimed to evaluate current scoring systems in predicting short-term and long-term mortality because of AH.

Patients And Methods: Records of 170 consecutive patients with AH admitted to a tertiary center between January 2005 and October 2015 were reviewed.

Endothelial cell dynamics in vascular remodelling.

In this ESCHM 2016 conference talk report, we summarise two recently published original articles Franco et al. PLoS Biology 2015 and Franco et al. eLIFE 2016.

A rare case of Burkitt's lymphoma of the duodenal bulb.

Gastrointestinal tract involvement in immunodeficiency-related Burkitt's lymphoma is not common and the duodenal involvement is very rare. We report the case of a 35-year-old man admitted because of abdominal pain, vomiting and weight loss. Human immunodeficiency virus infection was diagnosed and upper digestive tract endoscopy showed marked edema and hyperemia of the duodenal bulb with some violaceous areas.
