Background: Acute appendicitis (AA) is the most common surgical emergency worldwide. Its correct and early diagnosis is essential to avoid unnecessary surgeries and complications associated with its natural history. Objective: The aim of this study was to determine the diagnostic sensitivity and specificity of the RIPASA score in patients with suspected AA. Material and methods: This analytical, cross-sectional, observational and retrospective study included appendectomy specimens of patients of both sexes > 18 years operated on with clinical diagnosis of AA between January 1 and December 31, 2017. The histopathological examination of the appendectomy specimens was considered the gold standard diagnostic test. A score of 7.5 for the RIPASA score was chosen as cut-off value. Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) were calculated. Results: A total of 68 appendectomies were included; 57 (83.82%) specimens were positive for acute appendicitis. Mean age was 43.32 years. The histological diagnosis of AA was present in 32 (84.21%) men and in 25 (83.33%) women. For the RIPASA score, 54 patients had a true positive result (cut-off point ≥ 7.5 and positive histology for AA) with a sensitivity of 93%, specificity of 40%, PPV of 90%, NPV of 50%, positive likelihood ratio of 1.55 and negative likelihood ratio of 0.175. Conclusion: The RIPASA score has demonstrated excellent sensitivity and specificity for the clinical diagnosis of AA in a fast, simple and non-invasive fashion.

Introduction: Liver transplantation (LT) aims not only to obtain long survival, but also to achieve an excellent quality of life (QOL). The purpose of our study is to assess several QOL aspects of recipients after 1 year of LT and to identify potential factors that might be associated with impaired QOL. Materials and Methods: Retrospective analysis including LT between 2013 to 2021. The Liver Disease Quality of Life questionnaire (LDQOL 1.0), and the consent form to participate of this study were given personally or sent by e-mail. This questionnaire includes 111 items distributed within 20 domains. Fulminant liver failure, hepatorenal transplantation and underaged patients were excluded. Significance was explored using T tests. Differences were considered statistically significant at p < 0.05. Results: This study included 89 patients out of 360 LT (56% male) who answered the survey, age range 24.8-75 years (mean: 52.5). On average, the patients had to wait 360 days before undergoing LT. Primary etiologies of liver disease were: hepatitis C virus (22.5%), alcohol (22.5%), autoimmune cirrhosis (22.5%), primary biliary cirrhosis (14.6%), NASH (6.7%), primary sclerosing cholangitis (3.3%), cryptogenic (2.2%), and others (5.6%). Thirtyone LT also presented hepatocarcinoma (HCC). The vast majority (93%) had moderate to severe liver disease, with 46% Child-Pugh B and 47% Child-Pugh C. After 1 year LT, QOL was improved resulting with a mean of 83,69%. The general well-being domain rated lowest with 69%. Higher scores (89 -90%) were obtained on effects of liver disease, stigma of liver disease, physical limitations, emotional limitations and loneliness. There was a significant association between the Child-Pugh classification and body pain, emotional well-being, memory and stigma of liver disease (p< 0,05). Lower MELD scores (<18) showed better results after 1 year LT in energy/fatigue, emotional well-being, liver disease symptoms, effects of liver disease and hopelessness domains (p < 0,05). There was no significant difference when QOL was compared according etiology of chronic liver disease, gender, or age. Conclusion: After 1 year of LT, patients result on QOL show a significant improvement, even similar to results published on the common population, in most of the domains surveyed except for body pain, energy and emotional well-being which still need upgrade.
