Percutaneous tracheotomies (PCT) are commonly performed minimally invasive procedures involving the creation of an airway opening through an incision or puncture of the tracheal wall. While the medical intervention is crucial for critical care and the management of acute respiratory failure, tracheostomy complications can lead to severe clinical symptoms due to the alterations of the airways biomechanical properties/structures. The causes and mechanisms underlaying the development of these post-tracheotomy complications remain largely unknown.

Objective: Acute exacerbations of chronic rhinosinusitis (AECRS) are currently defined as a transient worsening of symptoms that return to baseline. This definition is narrow and can only be made retrospectively. The literature has studied this phenomenon from the physician perspective, yet a key stakeholder's-the patient's perspective is not well elucidated in the literature.

The development of e-cigarettes was initially hailed as a resource in facilitating a reduction in or cessation of cigarette smoking. Many users of e-cigarettes are 'dual users', smoking traditional cigarettes and e-cigarettes. The present qualitative study examines the factors that a group of 20 dual users considered to have been influential in their decisions to use e-cigarettes and their comparative evaluations of e-cigarettes and traditional cigarettes.

Policymakers have been slow to support family caregivers, and political agendas mostly fail to address the cost burdens, impact on employment and productivity, and other challenges in taking on long-term care tasks. This project set out to raise policymakers' awareness of family caregivers through proposals to Republican and Democratic party platforms during the 2016 political season. The Family Caregiver Platform Project (FCPP) reviewed the state party platform submission process for Democratic and Republican parties in all 50 states and the District of Columbia.

Polaron formation in poly(G)-poly(C) cations is investigated with density functional theory (DFT) and molecular mechanics (MM) employing a two-layer ONIOM method. In these calculations, the high layer, composed of all complementary base pairs, is treated by a DFT method, while the low layer, which includes the sugar-phosphate backbone, counterions and water molecules, is described by the AMBER force field. The high layer is the model system in which the charge transfer takes place.

The inhibition of Aurora kinases in order to arrest mitosis and subsequently inhibit tumor growth via apoptosis of proliferating cells has generated significant discussion within the literature. We report a novel class of Aurora kinase inhibitors based upon a phthalazinone pyrazole scaffold. The development of the phthalazinone template resulted in a potent Aurora-A selective series of compounds (typically >1000-fold selectivity over Aurora-B) that display good pharmacological profiles with significantly improved oral bioavailability compared to the well studied Aurora inhibitor VX-680.

The displacement of the iron(II) atom from the porphyrin plane in iron(II) porphyrin complexes is investigated with respect to the spin state of iron(II) employing density functional theory. In this study the quantum theory of atoms in molecules (QTAIM) is used to show that the atomic volume of iron is smaller in the quintet state of imidazolium ligated iron(II) porphyrin than in the triplet state. This is consistent with what has been found for free atoms and contradicts the original interpretation of structural studies with X-rays, which assumed that the out-of-plane displacement of iron from the porphyrin ring in the quintet state is due to the increased spatial size of the high-spin iron atom.
