Acute-on-chronic liver failure (ACLF) is a frequent syndrome associated with high mortality. The aims of the present study are: a) comparing the Chronic Liver Failure Consortium (CLIF-C) ACLF Model for End-Stage Liver Disease (MELD), MELD Sodium (MELD-Na) and Child-Turcotte-Pugh (CTP) scores for prediction of short/medium term mortality; b) identifying ACLF prevalence in patients admitted to the ward; and c) comparing mortality between non-ACLF/ACLF. Retrospective cohort study of 177 patients admitted to the Gastroenterology ward for acute decompensation of cirrhosis. We included 132 males. Alcohol was the cirrhosis cause/co-factor in 79.7% of cases. Infection was present in 40.7%. At admission, 19.8% of patients presented ACLF and 7.9% developed it during hospitalization (overall prevalence was 27.7%). ACLF grade 1 was diagnosed in 55.1% of the ACLF patients; grade 2, in 42.8%, and grade 3, in 2.0%. Infection (p < 0.001) and hepatic encephalopathy (p = 0.004) were more prevalent and C-reactive protein and leukocyte counts were higher in ACLF patients. ACLF 28 and 90-day mortality was 45.8% and 60.4%, respectively. The CLIF-C ACLF score was significantly superior to CTP, MELD, MELD-Na in predicting 28-day (AUROC 0.799 ± 0.078, 95% CI 0.637-0.891) and 90-day mortality (AUROC 0.828 ± 0.063, 95% CI 0.705-0.952). ACLF is highly prevalent in the ward. The new CLIF scores identify high mortality cirrhotic patients admitted to the ward and are better than their predecessors to predict ACLF patients' short/medium term mortality.

Background Inflammatory Bowel Disease is known for its extra intestinal manifestations, the oral cavity is no exception. Objectives The aim of this study was to evaluate the association between Inflammatory Bowel Disease and oral mucosa lesions and symptoms, and complementary to evaluate their possible relation with oral hygiene, smoking habits, drug therapy, duration and activity of the disease. Methods Patients were selected from the Gastroenterology Clinic of a Portuguese tertiary referral hospital. This sample consisted of 113 patients previously diagnosed with ulcerative colitis or Crohn’s disease along with a control group of 58 healthy individuals that were accompanying the study group patients to their appointments. Clinical interviews and clinical examinations were performed for data collection. Results The patients in the study group were more affected by oral symptoms (P=0.011), and showed a trend towards a higher incidence of oral mucosal lesions, even though statistical significance was not reached (8.8% versus 3.4% in the control group; P=0.159). Patients in active phase were the most affected. No differences were detected between Crohn’s disease and ulcerative colitis, or concerning smoking habits. The corticosteroid and immunosuppressant therapy seemed to increase the incidence of oral symptoms (P=0.052). The oral mucosa lesions increased and the oral symptoms decreased over the course of the disease, however without statistical significance. Conclusion Oral mucosa’s lesions and oral symptoms were positively associated with Inflammatory Bowel Disease, mainly during disease activity periods and conceivably, associated with corticosteroid and immunosuppressant therapy.

Background and Aims: Hemorrhoid disorders are common. This study aimed to assess the efficacy and safety of polidocanol foam injected at high doses with intravenous needle for the treatment of symptomatic internal hemorrhoids that prolapse or bleed. Methods: We evaluated 2,000 consecutive patients with prolapsed hemorrhoids (grades II/III/IV) recruited over 6 years. Foam injection was performed in one to four sessions with polidocanol 2%: 10 mL of the mixture (2 mL liquid plus air) or 20 mL (4 mL liquid plus air). The number of sessions and amount of foam injected depended on initial hemorrhoid size, compliance to receive foam, and clinical response. The mixture, prepared using a three-way tap connected to two 10/20-mL syringes, was injected immediately after preparation using an intravenous needle. The primary endpoint was self-reported satisfaction without major complications at 4 weeks. Results: Efficacy was very high, with 1,957 patients (98%) reporting satisfaction regarding blood loss control and prolapse reduction. The procedure was well tolerated: 1,838 patients (92%) presented mild/no pain. Objective reduction of prolapse volume was documented in 86% of reobserved cases. Complications were rare and usually minor: only 3 cases of clinically significant bleeding (0.15%), 2 of whom were on dual antiplatelet therapy plus oral anticoagulation, 2 cases of rectal abscess, 8 hemorrhoid thromboses, and 1 urinary retention requiring catheter (0.7% severe complications). Conclusions: Treatment of internal hemorrhoids with polidocanol foam injected in high doses is very effective and safe for the control of blood loss and prolapse, even for patients on anticoagulation/antiplatelet treatment.

BACKGROUND: Protein-calorie malnutrition is common in chronic liver disease (CLD) but adequate clinical tools for nutritional assessment are not defined. OBJECTIVE: In CLD patients, it was aimed: 1. Characterize protein-calorie malnutrition; 2. Compare several clinical, anthropometric and functional tools; 3. Study the association malnutrition/CLD severity and malnutrition/outcome. METHODS: Observational, prospective study. Consecutive CLD ambulatory/hospitalised patients were recruited from 01-03-2012 to 31-08-2012, studied according with age, gender, etiology, alcohol consumption and CLD severity defined by Child-Turcotte-Pugh. Nutritional assessment used subjective global assessment, anthropometry, namely body-mass index (BMI), triceps skinfold, mid upper arm circumference, mid arm muscular circumference and handgrip strength. Patients were followed during two years and survival data was recorded. RESULTS: A total of 130 CLD patients (80 men), aged 22-89 years (mean 60 years) were included. Most suffered from alcoholic cirrhosis (45%). Hospitalised patients presented more severe disease ( P <0.001) and worst nutritional status defined by BMI ( P =0.002), mid upper arm circumference ( P <0.001), mid arm muscular circumference ( P <0.001), triceps skinfold ( P =0.07) and subjective global assessment ( P <0.001). A third presented deficient/low handgrip strength. Alcohol consumption ( P =0.03) and malnutrition detected by BMI ( P =0.03), mid upper arm circumference ( P =0.001), triceps skinfold ( P =0.06), mid arm muscular circumference ( P =0.02) and subjective global assessment ( P <0.001) were associated with CLD severity. From 25 patients deceased during follow-up, 17 patients were severely malnourished according with triceps skinfold. Malnutrition defined by triceps skinfold predicted mortality ( P <0.001). CONCLUSION: Protein-calorie malnutrition is common in CLD patients and alcohol plays an important role. Triceps skinfold is the most efficient anthropometric parameter and is associated with mortality. Nutritional assessment should be considered mandatory in the routine care of CLD patients.

Head and neck cancer (HNC) patients who underwent percutaneous endoscopic gastrostomy (PEG) present malnutrition risk and speech impairments. Their assessment relies on objective anthropometric/laboratory data. Focusing on HNC PEG patients, our aims were to evaluate: 1) outcome; 2) nutritional status when the patients underwent PEG; and 3) association of nutritional status/outcome, creating a survival predictive model. We evaluated the outcome based on NRS 2002, dietary assessment, body mass index (BMI), mid-upper arm circumference (MUAC), triceps skinfold thickness (TSF), mid-arm muscle circumference (MAMC), albumin, transferrin, and cholesterol on the day of gastrostomy. Using BMI, TSF, MAMC, and laboratory data, a survival predictive model was created. Of the 234 patients (cancer stages III–IV), 149 died, 33 were still PEG-fed, and 36 resumed oral intake (NRS-2002≥3, caloric needs <50% in all). BMI was 12.7–43. 189, 197, and 168 patients displayed, respectively, low MUAC, TSF, and MAMC. 91, 155, and 119 patients displayed low albumin, transferrin, and cholesterol. Albumin, cholesterol, and transferrin were strongly associated with the outcome. A predictive model was created, discriminating between short-term survivors (<4 months) and long-term survivors. HNC patients were malnourished. Using anthropometric/laboratory parameters, a predictive model provides discrimination between patients surviving PEG for <4 months and long-term survivors. Teams taking care of PEG patients may provide special support to potential short-term survivors.
