Review Meta Analysis
Endovascular interventional modalities for haemorrhage control in abnormal placental implantation deliveries: a systematic review and meta-analysis.
To examine the evidence regarding the effectiveness and safety of endovascular interventional modalities for haemorrhage control in abnormal placentation deliveries. ⋯ • Endovascular intervention in abnormal placentation deliveries is effective in reducing blood loss. • Endovascular intervention did not result in longer operative time or hospital stay. • Prophylactic balloon occlusion of the abdominal aorta is superior to other modalities.
-
To investigate the role of 18F-FDG PET/CT to detect bone marrow (BM) involvement in paediatric non-Hodgkin lymphoma (NHL). ⋯ • PET/CT allows for accurate detection of bone marrow involvement. • Patterns of bone marrow FDG uptake are highly correlated with marrow disease. • Bone marrow biopsy could be omitted in selected paediatric patients.
-
To determine the utility of cervical spine MRI in blunt trauma evaluation for instability after a negative non-contrast cervical spine CT. ⋯ • MRI has limited utility after negative cervical CT in blunt trauma. • MRI is frequently positive for non-specific soft-tissue injury. • Unstable injury missed on CT is infrequent.
-
To predict ATRX mutation status in patients with lower-grade gliomas using radiomic analysis. ⋯ • ATRX in lower-grade gliomas could be predicted using radiomic analysis. • The LASSO regression algorithm and SVM performed well in radiomic analysis. • Nine radiomic features were screened as an ATRX-predictive radiomic signature. • The machine-learning model for ATRX-prediction was validated by an independent database.

To assess the frequency and anatomy of retro-oesophageal aortopulmonary collateral arteries (REMs) in patients with pulmonary atresia with ventricular septal defect and major aortopulmonary collateral arteries (PA-VSD-MAPCAs). ⋯ • Unifocalization is a very important surgical approach for PA-VSD-MAPCA patients. • The anatomical variability of REMs becomes clinically relevant in unifocalization. • CTA provides a non-invasive way to observe the anatomy of REMs. • REMs are associated with lower level, more lateral origin, more midsegment stenosis. • REMs tend to be posterior to the bronchus at the pulmonary hilum.
