Purpose: To Evaluate the MELD score as a predictor of 30-day mortality in patients undergoing elective TIPS procedures.
Methods: This was a retrospective, IRB-approved study. The medical records of all patients who underwent a TIPS procedure between May 1, 1999 and June 1, 2003 in a single institution were reviewed. Patients who underwent elective TIPS were selected. Elective TIPS was performed in 119 patients with a mean age of 55.1 (+/- 9.6) years. The MELD and Child-Pugh scores before TIPS, etiology of cirrhosis, portosystemic gradients before and after TIPS, procedure time, and procedural complications were obtained from the medical records. The MELD and Child-Pugh scores before TIPS were compared between the survivor group (SG) and the early death (EDG) group. The early death rate was calculated for MELD score subgroups (1-10, 11-17, 18-24, and >24). Data were analyzed using the Fisher exact test, chi-square test and independent-sample t-test. A p value of less than 0.05 was considered significant.
Results: Technical success rate was 100%. The early death rate was 10.9% (13/119). The mean MELD scores before TIPS were 19.4 (+/- 5.9) (EDG) and 14 (+/- 4.2) (SG) (p = 0.025). The early death rate was highest in the pre-TIPS MELD > 24 subgroup. The Child-Pugh scores were 9.0 (+/- 1.6) (SG) and 9.8 +/- 1.06 (EDG) (p = 0.08). The mean portosystemic gradients before TIPS were 20.5 (+/- 7.7) mmHg (EDG) and 22.7 (+/- 7.3) (SG) (p > 1) and the mean portosystemic gradients after TIPS were 6.5 (+/- 3.5) (EDG) and 6.9 (+/- 2.4) (SG) (p > 1). The mean procedural times were 95.6 (+/- 8.4) min (EDG) and 89.2 (+/- 7.5) min (SG) (p > 1). No early death was attributed to a fatal complication during TIPS.
Conclusion: The MELD score is useful in identifying patients at a higher risk of early death after an elective TIPS. On th basis of our results, we do not endorse elective TIPS in patients with MELD scores > 24.

Background: Severe pulmonary infection is the primary cause of death in children aged < 5 years. The early identification of pathogenic bacteria and targeted anti-infective therapies can significantly improve the prognosis of children with severe infections. This study aims to provide a reference for the rational use of antibiotics at an early stage in children with severe pulmonary infections.

Unlabelled: Sickle cell disease (SCD) is a global health problem causing premature deaths and preventable severe chronic complications. A priority goal to improve outcomes both in the short and long term is the screening for early diagnosis and access to specialized care. In Italy, as in other countries, no systematic national screening program is available.

Objectives: Immune checkpoint inhibitor (ICI)-containing treatment is currently prescribed as first-line treatment for all patients with advanced non-small cell lung cancer (NSCLC) without targetable driver mutations. However, only 30-45% of patients show no progression within 12 months after treatment start. Various biomarkers are being studied to save costly and potentially harmful treatment in non-responders.

Background: Lung cancer (LC) is a leading cause of cancer mortality in Argentina. Low-dose computed tomography (LDCT) had demonstrated higher efficacy than chest radiography as a screening method for early detection and reducing LC mortality. This study estimates the Budget Impact of implementing annual LDCT screening for individuals aged 55-74 with at least 30 pack-years of smoking in Argentina.
