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.

Choledocholithiasis is closely associated with bacterial infection and inflammation in the bile duct. Our previous studies showed that sphincter of Oddi laxity (SOL) significantly altered the bile microbiota and might contribute to the recurrence of biliary stones. However, the direct association among SOL, the bile microbiota, and choledocholithiasis recurrence is unclear. ⋯ Choledocholithiasis patients with and without SOL demonstrated significant differences in their microbial communities. SOL is a critical risk factor for the recurrence of choledocholithiasis after surgery. The presence of Clostridium may be potentially associated with the recurrence of SOL-induced choledocholithiasis.

Coronavirus disease 2019 (COVID-19), also known as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, first manifested in December 2019, and spread rapidly worldwide. Facing this lethal disease, there is an urgent need to develop potent therapies against SARS-CoV-2 infection. SARS-CoV-2 phylogenetically and symptomatically resembles SARS-CoV and Middle East Respiratory Syndrome Coronavirus (MERS-CoV). Numerous agents have been utilised during the severe acute respiratory syndrome (SARS) and Middle East Respiratory Syndrome (MERS) epidemics, which may show some benefit against SARS-CoV-2. ⋯ The protocol of this study has been submitted to the PROSPERO platform (https://www.crd.york.ac.uk/PROSPERO/), and the registration number is CRD42020168639.

Critical appraisal of the quality of clinical practice guidelines for idiopathic pulmonary fibrosis.
Clinical practice guidelines (CPGs) have long served as an essential tool for clinicians to rationalize their treatment in practice. However, the quality of guidelines varies greatly. The present study aimed to analyze high-quality CPGs of idiopathic pulmonary fibrosis (IPF) and highlight the potential for further improvement. ⋯ The methodological quality of selected IPF CPGs fluctuated greatly, and the full reporting rate was found to be quite low in some domains. In the future, we should focus not only on improving the methodological quality in the development of guidelines, but also on the reporting quality of guidelines.
