REVIEW
Michalis Mazonakis, John Damilakis
The appearance of a malignant disease during pregnancy is relatively rare. The use of external-beam radiation therapy is limited to non-pelvic tumors which are usually located above the diaphragm. However, supradiaphragmatic radiotherapy unavoidably exposes the fetus to secondary radiation due to head leakage, scatter from the machine and scatter produced inside the patient. This fetal exposure may be associated with an elevated risk for the development of deterministic harmful effects and/or carcinogenesis...

Over the last decade, percutaneous intervention for the treatment of aortic stenosis has become commonplace with >300,000 implantations performed worldwide. With this now being an established therapy, focus has shifted to the more intricate challenge of mitral and tricuspid valve disease, where there remains a large population of patients with unmet clinical needs. These complex anatomical structures demand unique approaches to treat a wide range of pathologies involving the valve leaflets, annulus and chordae...

Mitral regurgitation (MR) is the second most common valvular heart disease in the western world with a prevalence in the USA alone of two to four million people. MR is age-dependent and hence the MR burden is expected to increase with the increase in life expectancy observed in Europe and the USA. Medical and surgical treatment has been the cornerstone of the treatment as untreated MR results in poor prognosis. However, only a fraction of patients are offered surgical treatment due to high risk. With the success of transcatheter aortic valve implantation (TAVI), many transcatheter options have emerged to provide a less invasive option for these patients...

Noninvasive engineering models are now being used for diagnosing and planning the treatment of cardiovascular disease. Techniques in computational modeling and additive manufacturing have matured concurrently, and results from simulations can inform and enable the design and optimization of therapeutic devices and treatment strategies. The emerging synergy between large-scale simulations and 3D printing is having a two-fold benefit: first, 3D printing can be used to validate the complex simulations, and second, the flow models can be used to improve treatment planning for cardiovascular disease...

BACKGROUND: During total elbow arthroplasty (TEA), most of the joint capsule is removed, including many mechanoreceptors important for proprioception, which potentially limits the patient's postoperative functional recovery. We quantified proprioceptive loss by measuring the threshold to detection of passive motion (TTDPM) in patients after unilateral TEA compared with the contralateral side. METHODS: A continuous passive motion device moving the elbow at 0.5°/s was used to evaluate TTDPM in 8 patients (mean ± standard deviation age, 69...

Natural, synthetic or semisynthetic antibiotics are highly used to prevent or treat diseases in humans and animals, and to promote animal growth. This fact makes that antibiotics residues or their transformation products may be present in food or in the environment after human or animal excretion. For this reason, it is imperative to develop reliable and sensitive analytical methodologies for their analysis. The main aim of this work is to present and discuss the most recent applications of capillary electromigration methods for the analysis of antibiotics, including the developments and applications of their use as chiral selectors in CE...

BACKGROUND: The amputation of a foot or a leg is one of the complications caused by diabetes that creates fear. After the amputation, the patient becomes dependent on a caregiver, who is often not prepared for this new phase of life. Knowing the factors that influence care delivery in caregivers of amputee type 2 diabetes patients is important from an heuristic point of view, since very few studies have focused on this population. OBJECTIVES: This study analysed the predictors and moderators of quality of life, in caregivers of amputee patients due to type 2 diabetes...

Liposomes functionalized with monoclonal antibodies or their antigen-binding fragments have attracted much attention as specific drug delivery devices for treatment of various diseases including cancer. The conjugation of antibodies to liposomes is usually achieved by covalent coupling using cross-linkers in a reaction that might adversely affect the characteristics of the final product. Here we present an alternative strategy for liposome functionalization: we created a recombinant Fab antibody fragment genetically fused on its C-terminus to the hydrophobic peptide derived from pulmonary surfactant protein D, which became inserted into the liposomal bilayer during liposomal preparation and anchored the Fab onto the liposome surface...
