Thrombotic complications associated with peripherally inserted central catheters (PICCs) are common, as most synthetic materials when placed in the presence of serum often result in platelet activation, fibrin deposition, thrombotic occlusion and potentially embolization. A current innovation focus has been the development of anti-thrombogenic catheter materials, including hydrophilic and hydrophobic surfaces. These are being incorporated into PICCs in an attempt to prevent the normal thrombotic cascade leading to patient harm...

Fibromyalgia affects more than 5 million people in the United States and has a detrimental impact on individuals' quality of life. Current pharmacological treatments provide limited benefits to relieve the pain of fibromyalgia, along with a risk of adverse effects; a scenario that explains the increasing interest for multimodal approaches. A tailored strategy to focus on this dysfunctional endogenous pain inhibitory system is transcranial direct current stimulation (tDCS) of the primary motor cortex. By combining tDCS with aerobic exercise, the effects can be optimized...

Maria F Paton, Klaus K Witte
Heart failure is a common finding in patients with pacemakers implanted for bradycardia, with cross-sectional and longitudinal studies contributing to the growing consensus that right ventricular pacing can cause adverse cardiac remodeling and left ventricular systolic dysfunction increasing the risk of hospitalization and death. An unselected approach using cardiac resynchronization therapy from the time of first implant in patients with heart block has produced equivocal results. Contemporary research has therefore begun to focus on the stratification of patients' risk of pacemaker-associated impairment to permit focused, personalized management...

The use of telepathology in intraoperative consultations has been increasing due to limited time and availability of pathologists, and the demand for increased access to pathology subspecialists in difficult cases. The five main categories of telepathology are: 1) static, 2) dynamic, 3) robotic, 4) whole slide imaging (WSI), and 5) hybrid methods. The majority of these methods have been found to offer diagnostic accuracy rates similar to conventional microscopy, at the cost of slightly prolonged time to evaluate slides...

Stent-assisted coiling (SAC) has widened indications of endovascular treatment of intracranial aneurysms (wide-neck, fusiform aneurysms); moreover, it is associated with more stable anatomical results. Besides the development of other techniques such as flow diverter stents, bifurcation stents, or intrasaccular flow disruptors, SAC remains one of the most used endovascular techniques because it provides good clinical and anatomical results for most aneurysms. Several devices based on the same principle are available and have undergone many adaptations and developments over 20 years of intracranial stenting...

Marieke C Van Der Molen, Karin Klooster, Jorine E Hartman, Dirk-Jan Slebos
Bronchoscopic lung volume reduction with endobronchial valves is a recently acknowledged treatment option in patients with severe emphysema and absence of interlobar collateral ventilation. In endobronchial valve treatment, implantation of one-way valves leads to deflation of a hyperinflated lung lobe. Multiple studies showed significant improvements in lung function, exercise capacity, and quality of life in this patient subgroup which often did not have any remaining treatment options. Areas covered: In this review, efficacy outcomes and adverse events of endobronchial valve treatment are summarized...

The Lotus valve system (Boston Scientific, Marlborough, Massachusetts, USA) consists of a braided wire Nitinol™ frame with three bovine pericardial leaflets. The valve is deployed by controlled mechanical expansion which allows recapturing/repositioning and full retrievability. Areas covered: While this system offers a unique seal, which conforms to irregular surfaces, thereby minimizing paravalvular leak, its main downfall is a high rate of new pacemaker implantation. This had been partially addressed with the design of the Depth Guard™ mechanism to optimize deployment by early anchoring and limiting the depth of implant...
