High-intensity focused ultrasound (HIFU) is widely applied to tumors in clinical practice due to its minimally invasive approach. However, several issues lower therapeutic efficiency in some cases. Many synergists such as microbubbles and perfluorocarbon nanoparticles have recently been used to improve HIFU treatment efficiency, but none were determined to be effective and safe in vivo. In this study, nanoscale bubble-generating liposomes (liposomes containing ammonium bicarbonate [Lip-ABC]) were prepared by film hydration followed by sequential extrusion...

REVIEW
Renan Bezerra Lira, Thiago Celestino Chulam, Luiz Paulo Kowalski
In the last three decades, otolaryngology and head and neck oncological surgery have shown remarkable progress with the development of several modalities of endoscopic-assisted minimally invasive surgeries. More recently, the Da Vinci robotic surgery system has promoted the development of several surgical approaches with less morbidity and better cosmetic results, including the transaxillary and retroauricular approaches for thyroid surgery and neck dissections. In South America, there are several shortcomings regarding financial resources as well as the lack of support for innovation leading to a significant delay in adoption of numerous technological advances in medical practice...

Triple arthrodesis has a significant role in the management of hindfoot osteoarthritis and deformity. Traditionally, it is an open procedure with extensive soft tissue dissection. Arthroscopic triple arthrodesis would appear to provide good visualization and preparation of the fusion surfaces while preserving the soft tissue envelope. The purpose of this Technical Note is to describe a minimally invasive approach of triple arthrodesis to correct chronic flatfoot deformity.

The design of injectable hydrogel systems addresses the growing demand for minimally invasive approaches for local and sustained delivery of therapeutics. We developed a class of hyaluronic acid (HA) hydrogels that form through noncovalent guest-host interactions, undergo disassembly (shear-thinning) when injected through a syringe and then reassemble within seconds (self-healing) when shear forces are removed. Its unique properties enable the use of this hydrogel system for numerous applications, such as injection in vivo (including with cells and therapeutic molecules) or as a 'bioink' in 3D-printing applications...

The transfusion of platelet concentrates prepared from allogeneic single or pooled donations is a standard procedure in transfusion medicine to stop or prevent bleeding in cancer patients with thrombocytopenia undergoing surgery, chemotherapy and/or radiotherapy. While platelet transfusion may appear reasonable in many instances, greater scientific and medical attention should however be given to the possibly insidious impact of transfused platelets on the outcome of cancers. Indeed platelets and the microvesicles they release possess all the biological ingredients capable of supporting tumor growth, protecting circulating tumor cells, and to contributing to metastatic invasion...

BACKGROUND: Safety in the operating room is dependent on the team's non-technical skills. The importance of non-technical skills appears to be different for minimally invasive surgery as compared with open surgery. The aim of this study was to identify which non-technical skills are perceived by team members to be most important for patient safety, in the setting of video-assisted thoracoscopic surgery (VATS) lobectomy. METHODS: This was an explorative, semistructured interview-based study with 21 participants from all four thoracic surgery centers in Denmark that perform VATS lobectomy...
