This study aimed to determine the natural course of patent ductus arteriosus (PDA) with noninterventional conservative management and whether the presence and/or prolonged duration of hemodynamically significant (HS) PDA increased the risk of mortality and morbidities in extremely preterm (EPT) infants. We retrospectively reviewed the medical records of EPT infants born at 23-28 weeks of gestation (n = 195) from January 2011 to June 2014, when PDA was managed with noninterventional conservative treatment. We stratified infants into three subgroups of 23-24, 25-26, and 27-28 weeks and analyzed the prevalence and natural evolution of HS PDA, defined as ventilator dependency and PDA size ≥2 mm...

A patent foramen ovale (PFO) is a remnant interatrial communication, best diagnosed with transoesophageal echocardiography (TOE) and bubble study. Although quite common and often asymptomatic, PFO is associated with cryptogenic stroke and migraine. Approximately one-half of patients with a cryptogenic stroke have a PFO, and the dilemma regarding whether or not to proceed with percutaneous device closure, to reduce the risk of future recurrent events due to paradoxical embolism, has been subject to debate for nearly two decades...

OBJECTIVE: To investigate whether preoperative echocardiography findings determine postoperative continuous-flow left ventricular assist device outcomes. METHODS: From January 2003 to June 2017, 490 patients received a durable, continuous-flow left ventricular assist device. Two-step clustering of parameters including heart rate and preoperative echocardiographic findings (ie, left ventricular [LV] ejection fraction, right ventricular [RV] function, aortic insufficiency, mitral regurgitation [MR], tricuspid regurgitation [TR]) was performed and identified 5 distinct clusters associated with LV failure: group 1: moderate right ventricular dysfunction (RVD), severe MR and mild TR (n = 110); group 2: severe RVD, severe MR and TR (n = 64); group 3: moderate RVD and severe aortic insufficiency (n = 16); group 4: mild RVD and mild valvular pathology (n = 163); and group 5: moderate-severe RVD and mild valvular pathology (n = 137)...

Modulation of liquid-liquid and liquid-hydrogel phase transitions is central to avoid the cytotoxic aggregation of proteins in eukaryotic cells, but knowledge on its relevance in bacteria is limited. Here the power of optogenetics to engineer proteins as light-responsive switches has been used to control the balance between solubility and aggregation for LOV2-WH1, a chimera between the plant blue light-responsive domain LOV2 and the bacterial prion-like protein RepA-WH1. These proteins were first linked by fusing, as a continuous α-helix, the C-terminal photo-transducer Jα helix in LOV2 with the N-terminal domain-closure α1 helix in RepA-WH1, and then improved for light-responsiveness by including mutations in the Jα moiety...

In microelectromechanical systems (MEMS) switches, the microcontact is crucial in determining reliability and performance. In the past, actual MEMS devices and atomic force microscopes (AFM)/scanning probe microscopes (SPM)/nanoindentation-based test fixtures have been used to collect relevant microcontact data. In this work, we designed a unique microcontact support structure for improved post-mortem analysis. The effects of contact closure timing on various switching conditions (e.g., cold-switching and hot-switching) was investigated with respect to the test signal...

OBJECTIVES: The majority of human chronic wounds contain bacterial biofilms, which produce proteases and retard the resolution of inflammation. This in turn leads to elevated patient protease activity. Chronic wounds progressing towards closure show a reduction in proteolytic degradation. Therefore, the modulation of protease activity may lead to the faster healing of chronic wounds. Antimicrobials are used to control biofilm-based infection; however, some of them also exhibit the inhibition of matrix metalloproteinases and bacterial proteases...

The current guidelines recommend a minimum of 6 months of antithrombotic and antibiotic prophylaxis following septal occluding device placement for transcatheter closure of atrial septal defect. Full neoendothelialization is thought to be completed within 6 months of device implantation; however, there is no method available that can assess the level of neoendothelialization in vivo. This report therefore evaluates endothelialization in vivo and demonstrates that 6 months of postimplantation prophylactic therapy may not provide sufficient time for adequate endothelialization...

Although reported failure rates of the Watchman device are low, the ballshaped device is not suitable for shallow and multilobed left atrial appendages (LAAs). The LAmbre device is available in two configurations - standard (cover 4-6 mm larger in diameter than the umbrella) and special (cover 12- 14 mm larger than the umbrella) - which allows the closure of a wide range of LAA anatomies. This case illustrates that the LAmbre device can be used for complex LAA anatomies that are not suitable for the Watchman device...
