Mucinous cystic neoplasms (MCN) of the pancreas are rare mucin-producing cystic tumors. As they harbor malignant potential, surgical resection is frequently performed. Current guidelines recommend surgery in asymptomatic patients only for MCN exceeding 4 cm. The aim of this study was to identify radiological and clinical risk factors for malignancy in a single-center cohort of MCN. ⋯ Malignant potential of MCN should not be underestimated and a close clinical and radiological follow-up is mandatory in all suspected cases. This is especially important for small lesions. Risk assessment should not rely only on tumor size but consider all clinical, radiological and laboratory findings of each case. Follow-up should be performed by experienced surgeons and radiologists in high volume centers for pancreatic surgery. Surgery should be performed in all cases in which malignancy is suspected.

It is uncertain whether airway pressure release ventilation (APRV) is better than low tidal volume ventilation (LTVV) for patients with acute respiratory distress syndrome (ARDS). The purpose of this meta-analysis was to compare APRV and LTVV on patients with ARDS. ⋯ The meta-analysis showed that APRV could reduce hospital mortality, duration of ventilation and ICU stay, improve lung compliance, oxygenation index, and MAP compared with LTVV for patients with ARDS. We found APRV to be a safe and effective ventilation mode for patients with ARDS.
