Otitis media with effusion (OME) is the focus of an updated multidisciplinary clinical practice guideline published by the American Academy of Otolaryngology-Head and Neck Surgery Foundation (AAO-HNSF) and the American Academy of Pediatrics (AAP). Based on data from clinical trials, the guideline recommends against using antihistamines, antibiotics, oral steroids, and intranasal steroids for OME. To understand practice patterns related to these guidelines, we assessed nationally representative data. Despite controlling for age, sex, race/ethnicity, and other potential confounders individualized for each medication class, an increased risk of antihistamine (odds ratio [OR], 3...

Osteoarthritis is the most common joint disorder in the world and its incidence is rising. In Western populations it is one of the most frequent causes of pain, loss of function and disability in adults. The estimated lifetime risk for knee osteoarthritis is approximately 40% in men and 47% in women. The diagnosis of osteoarthritis is complex due to a lack of specific physical and/or laboratorial findings. The American College of Rheumatology (ACR) has recommended using the following criteria for the diagnosis of knee osteoarthritis: chronic knee pain (lasting for more than 6 weeks) and at least three of the following: • Age over 50 years old...

Well-ordered periodic nanostructures are excellent substrates for many surface-enhanced Raman spectroscopy (SERS) applications. Conventional fabrication approaches such as high precision electron beam lithography or focused ion beam produce high resolution nano-features with great reproducibility at the expense of low throughput. In this work, a highly sensitive and scalable AAO-nano-fibre (ANF) SERS substrate is demonstrated by optimising the second anodisation time of the standard two-step anodisation of aluminium and performing an additional wet etching step on the resulting AAO substrate...

INTRODUCTION: The SICOT Conference Committee continually tries to improve the quality of presentations at their annual international meetings. However to the author's best knowledge, no previous study has been undertaken to determine abstract quality. This study aimed to determine the five-year publication rate of presentations made at the 2009 SICOT Annual International Conference (AIC), recognise predictors of full-text publication, identify inconsistencies between presentations and publications, and determine presentation-publication delay...

BACKGROUND: A comprehensive approach to the evaluation of biologic therapies for musculoskeletal conditions is required to guide appropriate future use. Clinical studies evaluating platelet-rich plasma (PRP) and mesenchymal stem cells (MSCs) are limited by inadequate reporting of scientific details critical to outcome. We developed minimum reporting requirements for clinical studies evaluating PRP and MSCs using Delphi consensus methods. METHODS: The need for consensus on the minimum reporting requirements for studies evaluating biologics was identified at the American Academy of Orthopaedic Surgeons/Orthopaedic Research Society (AAOS/ORS) Biologic Treatments for Orthopaedic Injuries Symposium in 2015 and the American Orthopaedic Society for Sports Medicine (AOSSM) Biologic Treatments for Sports Injuries II Think Tank in 2015...

BACKGROUND: Body surface area (BSA)-indexed Z-scores are used to assess the ascending aorta (AAo) and diagnose aortic dilation (AoD) in children. BSA is directly related to body weight and corresponds to body mass index (BMI). We hypothesized extremes in BMI alter interpretation of aortic size in pediatric patients with AoD. METHODS: We reviewed all echocardiograms with a diagnosis of AoD performed at our institution from January 2013 through June 2013. Those with an age <2 or >20 years, history of aortic root surgery, or inadequate images were excluded...

This paper describes the preparation of nanoarrays composed of silver nanoparticles (AgNPs: 20-50 nm) for use as surface-enhanced Raman scattering (SERS) substrates. The AgNPs were grown on porous anodic aluminum oxide (AAO) templates by electrochemical plating, and the inter-channel gap of AAO channels is between 10 and 20 nm. The size and interparticle gap of silver particles were adjusted in order to achieve optimal SERS signals and characterized by scanning electron microscopy, atomic force microscopy, and Raman spectroscopy...

We report the impact of geometrical constraint on intramolecular interactions in self-assembled monolayers (SAMs) of alkylphosphonates grown on anodically oxidized aluminum (AAO). Molecular order in these films was determined by sum frequency generation (SFG) spectroscopy, a more sensitive measure of order than infrared absorption spectroscopy. Using SFG we show that films grown on AAO are, within detection limits, nearly perfectly ordered in an all-trans alkyl chain configuration. In marked contrast, films formed on planar, plasma-oxidized aluminum oxide or α-Al2O3 (0001) are replete with gauche defects...

BACKGROUND: Admixture analysis of age at onset (AAO) has helped delineating the clinical profile of early onset (EO) bipolar disorder (BD). However, there is scarce evidence comparing the distributional properties of AAO as well as the clinical features of EO BD type 1 (BD1) with EO BD type 2 (BD2). To this end, we studied 515 BD patients (224 BD1, 279 BD2, and 12 BD not otherwise specified [NOS]) diagnosed according to DSM-IV-TR criteria. METHODS: AAO was defined as the first reliably diagnosed hypo/manic or depressive episode according to diagnostic criteria...

This work reports on the electrodeposition of rhodium (Rh) nanowires with a controlled surface morphology synthesized using an anodic aluminum oxide (AAO) template. Vertically aligned Rh nanowires with a smooth and coarse morphology were successfully deposited by adjusting the electrode potential and the concentration of precursor ions and by involving a complexing reagent in the electrolyte solution. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) analyses were used to follow the morphological evolution of Rh nanowires...

In this work, we report the design and the fine-tuning of boron nitride single nanopore and nanoporous membranes by atomic layer deposition (ALD). First, we developed an ALD process based on the use of BBr3 and NH3 as precursors in order to synthesize BN thin films. The deposited films were characterized in terms of thickness, composition, and microstructure. Next, we used the newly developed process to grow BN films on anodic aluminum oxide nanoporous templates, demonstrating the conformality benefit of BN prepared by ALD, and its scalability for the manufacturing of membranes...

As a new type of energy harvesting device, the triboelectric nanogenerator (TENG) can convert almost all kinds of mechanical energy into electricity based on the coupling of triboelectrification and electrostatic induction. Here, a novel TENG is constructed with a conducting polymer polypyrrole nanowire (PPy NW) electrode, which is prepared by an electrochemical polymerization method with anodic aluminum oxide (AAO) as the template. The PPy NW-based TENG shows high output performance with a maximum short circuit current density of 23...

Lasiodiplodia theobromae (Pat.) Griff. & Maubl. is a major pathogen causing decay of harvested longan fruit. The roles of energy status regulated by 2,4-dinitrophenol (DNP) and adenosine triphosphate (ATP) in disease development regarding respiratory metabolism of L. theobromae-inoculated "Fuyan" longan fruit were studied. Compared with L. theobromae-inoculated longans, DNP treatment could promote the index of fruit disease, accelerate the decrease in energy charge, increase respiration rate and the activities of respiratory terminal oxidases like CCO, AAO and PPO, elevate contents of NAD and NADH, but decrease NAD kinase activity, as well as contents of NADP and NADPH; however, exogenous ATP supply acted contrarily...

Cochrane reviews indicate there is very limited support for all forms of sound therapy and cognitive behavioral therapy has the strongest support. American Academy of Otolaryngology (AAO) recently published some guidelines which recommends Cognitive Behavioral Therapy (CBT) for tinnitus intervention, and only indicates that sound therapy should be considered an "option" for intervention. Nevertheless, acoustic therapy could lead to cause changes in the tinnitus perception and has been appreciated by the affected people for years...

In this work we explore the effect of surface nanoarchitecture of polystyrene (PS) and polystyrene-b-poly(acrylic acid) (PS-b-PAA) diblock copolymer films on cell viability. PS and PS-b-PAA have been nanopatterned at temperatures of 110, 120 and 140°C using nanoporous aluminium oxide membranes (AAO) as a template. Surface architecture strongly depends on the infiltration temperature and the nature of the infiltrated polymer. High patterning temperatures yield hollow fibre shape architecture at the nanoscale level, which substantially modifies the surface hydrophobicity of the resulting materials...
