Sarcoidosis and ulcerative colitis: overlap or coexistence.

We show an unusual case of ulcerative colitis and sarcoidosis. This case has detailed images of skin lesions, biopsies and PET-CT results. There is limited evidence regarding the association of inflammatory bowel disease and other granulomatous diseases, especially sarcoidosis.

Validation of the CALL score as a mortality prediction tool in a cohort of hospitalized COVID-19 patients in Chile.

Introduction: The CALL score is a predictive tool for respiratory failure progression in COVID-19. Whether the CALL score is useful to predict short- and medium-term mortality in an unvaccinated population is unknown. Materials and methods: This is a prospective cohort study in unvaccinated inpatients with a COVID-19 pneumonia diagnosis upon hospital admission. Patients were followed up for mortality at 28 days, 3, 6, and 12 months. Associations between CALL score and mortality were analyzed using logistic regression. The prediction performance was evaluated using the area under a receiver operating characteristic curve (AUROC). Results: A total of 592 patients were included. On average, the CALL score was 9.25 (±2). Higher CALL scores were associated with increased mortality at 28 days [univariate: odds ratio (OR) 1.58 (95% CI, 1.34-1.88), p < 0.001; multivariate: OR 1.54 (95% CI, 1.26-1.87), p < 0.001] and 12 months [univariate OR 1.63 (95% CI, 1.38-1.93), p < 0.001; multivariate OR 1.63 (95% CI, 1.35-1.97), p < 0.001]. The prediction performance was good for both univariate [AUROC 0.739 (0.687-0.791) at 28 days and 0.869 (0.828-0.91) at 12 months] and multivariate models [AUROC 0.752 (0.704-0.8) at 28 days and 0.862 (0.82-0.905) at 12 months]. Conclusion: The CALL score exhibits a good predictive capacity for short- and medium-term mortality in an unvaccinated population.

[Comparative evaluation of survival prognosis using MELD or Child-Pugh scores in patients with liver cirrhosis in Chile]. / Evaluación comparativa entre MELD y Child-Pugh como escalas pronósticas de sobrevida en pacientes con cirrosis hepática en Chile.

BACKGROUND: Currently, most liver units use the Child-Pugh (CP) or the Model for End-Stage Liver Disease (MELD) scores to establish survival prognosis among patients with liver cirrhosis. Which classification is superior, is not well defined. AIM: To compare CP and MELD classification scores to predict survival among adult patients with liver cirrhosis in Chile. MATERIAL AND METHODS: Follow-up of 137 consecutive adult patients with liver cirrhosis aged 59 ± 12 years (55% women). The diagnosis was reached by clinical, laboratory and image studies at three different centers of Santiago. Patients were staged with CP and MELD classification scores at baseline and followed over a period of 12 months. The predictive capacity of the scores for survival was analyzed using a multivariate statistical analysis (Kaplan-Meier curves). RESULTS: The most common etiology was alcohol (37.9%). The actuarial survival rate was 79.6% at 12 months of follow-up. When comparing groups with areas under curve of receiver operating characteristic curves (AUROC), there was no statistically significant difference in survival between less severe and advanced disease, assessed with both survival scales. The AUROC for MELD and CP were 0.80 and 0.81, respectively. CONCLUSIONS: This clinical study did not find a statistically significant difference between the two classifications for the prediction of 12 months survival in patients with cirrhosis.
