We report the case of a 48-year-old woman who developed severe septic shock and lung injury after community-acquired pneumonia. She was supported on arteriovenous extracorporeal membrane oxygenation (ECMO) for 19 days. To facilitate decannulation and separation from ECMO, we began trials of high-frequency percussive ventilation (HFPV) using the volumetric diffusive respiration ventilator VDR-4 (Percussionaire Corp, Sandpoint, Idaho) for 4 consecutive days (1 before and 3 after). Decannulation was achieved successfully, and the patient was transferred to the floor 3 months later...

Fetal interventions have been performed for some congenital heart diseases. However, these procedures have not gained wide acceptance due to concerns about their efficacy and safety. The aim of this study was to report on a preliminary experience with fetal cardiac interventions in Brazil. Twenty-two cardiac interventions were performed in 21 fetuses. Thirteen fetuses had critical aortic stenosis (CAS), 4 had hypoplastic left heart syndrome (HLHS) and intact interatrial septum or small patent foramen ovale, 1 had pulmonary atresia with intact ventricular septum (IVS), and 3 had critical pulmonary stenosis (CPS)...

REVIEW
Cleisson Fábio Andrioli Peralta, Ricardo Barini
This is a traditional (narrative) review with the objective of highlighting the contribution of obstetric ultrasonography (US) between the 11th and 14th week of pregnancy, commonly called first trimester anomaly scan. In addition to being used for the screening of chromosomal anomalies, US can be employed during this period to confirm or determine gestational age, evaluate fetal anatomy, diagnose malformations, screen major structural abnormalities and genetic syndromes, define the prognosis of pregnancy, diagnose and characterize multiple pregnancies, and screen preeclampsia and intrauterine growth restriction...

BACKGROUND: Oesophagogastroduodenoscopy is currently recommended for the screening of varices in cirrhosis. In addition to the assessment of varices, oesophagogastroduodenoscopy can detect conditions that, while unrelated to portal hypertension, may require treatment. AIMS: We evaluated in a large cohort of cirrhotic patients the prevalence of upper digestive findings other than oesophagogastric varices, the associations between upper gastrointestinal findings, portal hypertension and features of cirrhosis, and the incidence of new lesions in the course of a surveillance program...

We show here that constant velocity steered molecular dynamics (SMD) simulations of alpha-helices in a vacuum present a well defined plateau in the force-extension relationship for homopolypeptides having more than (approximately) twenty residues. With the processes being far away from equilibrium, the energies strongly depend on the stretching velocity. Importantly, for a given velocity variation, the energy variation depends also on the helix sequence. Additionally, our observations show that homopolypeptides made of ten different amino acids (Ala, Cys, Gln, Ile, Leu, Met, Phe, Ser, Thr and Val) present a linear helix-coil transition...
