Chronic cough, defined as cough lasting 8 weeks or more in adults, accounts for approximately 16 million outpatient visits per year. Chronic cough exerts a significant burden on the quality of life of patients, which is often why they initially seek treatment. Various factors have contributed to the high cost associated with the burden of chronic cough, from multiple referrals and unnecessary repeat testing to polypharmacy and development of comorbidities due to lack of proper treatment. Although treatment guidelines for chronic cough are available, they vary in their recommendations. There are no FDA-approved agents indicated specifically for chronic cough at this time, but medications such as inhaled corticosteroids and narcotic antitussives are frequently used for treatment, while speech and behavioral therapy have also been potential options. New targeted therapies in the clinical pipeline are expected to expand the treatment landscape and meet the unaddressed gaps for safe and efficacious agents that can provide relief and better management for patients. Access to appropriate care based on clinical guidelines is associated with favorable outcomes. Managed care organizations should consider treatment guidelines, patient factors, and emerging pharmacologic as well as nonpharmacologic treatment options to create a streamlined approach to managing chronic cough treatment in an evidence-based and cost-effective manner.Chronic cough is a severely debilitating condition that results in individuals coughing hundreds to thousands of times per day. Unfortunately, at the time of this writing, the majority of treatments currently available address acute cough and have minimal efficacy for chronic cough. There are no current FDA-approved pharmacologic treatments for chronic cough, resulting in a large, unmet need for patients. Recent advancements in the understanding of the chronic cough reflex and suspected neurobiology have led to the development of novel therapeutic targets to bridge this unmet treatment need. Current American College of Chest Physicians and European guidelines recommend a thorough workup but differ in individual pharmacologic treatment recommendations. All patients should be evaluated for red-flag symptoms and any underlying conditions that may explain the patient's chronic cough. Historical treatments, such as opiates and neuromodulators, have been used with limited success. Emerging agents that target specific channel receptors have shown initial positive benefits concerning cough frequency, severity, and quality of life and may become available on the market as they have shown to be generally well tolerated without any safety concerns in clinical studies.Despite chronic cough being one of the most frequent reasons for both primary care and specialty physician visits, its diagnosis and treatment remain challenging. The most common causes are upper airway cough syndrome, asthma, and gastroesophageal reflux disease; however, new research has implicated a cough hypersensitivity syndrome that may link many underlying etiologies. To accurately diagnose and treat patients with chronic cough, a thorough understanding of the various definitions, epidemiology, and pathophysiology is crucial. This article reviews these factors as well as the healthcare and socioeconomic burden of chronic cough.A key factor for improving the sensitivity and performance of immunosensors based on mechanical-plasmonic methods is the orientation of the antibody proteins immobilized on the inorganic surface. Although experimental techniques fail to determine surface phenomena at the molecular level, modern simulations open the possibility for improving our understanding of protein-surface interactions. In this work, replica exchange molecular dynamics (REMD) simulations have been used to model the IgG1 protein tethered onto the amorphous silica surface by considering a united-atom model and a relatively large system (2500 nm2 surface). Additional molecular dynamics (MD) simulations have been conducted to derive an atomistic model for the amorphous silica surface using the cristobalite crystal structure as a starting point and to examine the structure of the free IgG1 antibody in the solution for comparison when immobilized. Analyses of the trajectories obtained for the tethered IgG1, which was sampled considering 32 different temperatures, have been used to define the geometry of the protein with respect to the inorganic surface. The tilt angle of the protein with respect to the surface plane increases with temperature, the most populated values being 24, 66, and 87° at the lowest (250 K), room (298 K), and the highest (380 K) temperatures. This variation indicates that the importance of protein-surface interactions decreases with increasing temperature. The influence of the surface on the structure of the antibody is very significant in the constant region, which is directly involved in the tethering process, while it is relatively unimportant for the antigen-binding fragments, which are farthest from the surface. These results are expected to contribute to the development of improved mechanical-plasmonic sensor microarrays in the near future.Sr2CrO2Cr2As2 and Ba2CrO2Cr2As2 with Cr2+ ions in CrO2 sheets and in CrAs layers crystallize with the Sr2Mn3Sb2O2 structure (space group I4/mmm, Z = 2) and lattice parameters a = 4.00800(2) Å, c = 18.8214(1) Å (Sr2CrO2Cr2As2) and a = 4.05506(2) Å, c = 20.5637(1) Å (Ba2CrO2Cr2As2) at room temperature. Powder neutron diffraction reveals checkerboard-type antiferromagnetic ordering of the Cr2+ ions in the arsenide layers below TN1_Sr, of 600(10) K (Sr2CrO2Cr2As2) and TN1_Ba 465(5) K (Ba2CrO2Cr2As2) with the moments initially directed perpendicular to the layers in both compounds. Checkerboard-type antiferromagnetic ordering of the Cr2+ ions in the oxide layer below 230(5) K for Ba2CrO2Cr2As2 occurs with these moments also perpendicular to the layers, consistent with the orientation preferences of d4 moments in the two layers. BIBF 1120 In contrast, below 330(5) K in Sr2CrO2Cr2As2, the oxide layer Cr2+ moments are initially oriented in the CrO2 plane; but on further cooling, these moments rotate to become perpendicular to the CrO2 planes, while the moments in the arsenide layers rotate by 90° with the moments on the two sublattices remaining orthogonal throughout [behavior recently reported independently by Liu et al.
