Development of a Preoperative Neuroscience Educational Program for Patients with Lumbar Radiculopathy

ABSTRACT Louw A, Butler DS, Diener I, Puentedura EJ: Development of a preoperative neuroscience educational program for patients with lumbar radiculopathy. Am J Phys Med Rehabil 2013;92:00Y00. Postoperative rehabilitation for lumbar radiculopathy has shown little effect on reducing pain and disability. Current preoperative education programs with a focus on a biomedical approach feature procedural and anatomical information, and these too have shown little effect on postoperative outcomes. This report describes the development of an evidence-based educational program and booklet for patients undergoing lumbar surgery for radiculopathy using a recently conducted systematic review of neuroscience education for musculoskeletal pain. The previous systematic review produced evidence for neuroscience education as well as best-evidence synthesis of the content and delivery methods for neuroscience education for musculoskeletal pain. These evidence statements were extracted and developed into patient-centered messages and a booklet, which was then evaluated by peer and patient review. The neuroscience educational booklet and preoperative program convey key messages from the previous systematic review aimed at reducing fear and anxiety before surgery and assist in developing realistic expectations regarding pain after surgery. Key topics include the decision to undergo surgery, pain processing, peripheral nerve sensitization, effect of anxiety and stress on pain, surgery and the nervous system, and decreasing nerve sensitization. Feedback from the evaluations of the booklet and preoperative program was favorable from all review groups, suggesting that this proposed evidence-based neuroscience educational program may be ready for clinical application

Iodine monoxide in the north subtropical free troposphere

Iodine monoxide (IO) differential slant column densities (DSCD) have been retrieved from a new multi-axis differential optical absorption spectroscopy (MAX-DOAS) instrument deployed at the Iza˜na subtropical observatory as part of the Network for the Detection of Atmospheric Composition Change (NDACC) programme.We acknowledge the support of the European Commission through the GEOmon (Global Earth Observation and Monitoring) Integrated Project under the 6th Framework Program (contract number FP6-2005-Global-4-036677) and NORS (Demonstration Network Of ground-based Remote Sensing Observations in support of the GMES Atmospheric Service) Integrated Project under the 7th Framework Program (contract number FP7-SPACE- 2011-284421)

NO2 climatology in the northern subtropical region: diurnal, seasonal and interannual variability

Daily NO2 vertical column density (VCD) has been routinely measured by zenith sky spectroscopy at the subtropical station of Izaña (28° N, 16° W) since 1993 in the framework of the Network for the Detection of Atmospheric Composition Change (NDACC). Based on 14 years of data the first low latitude NO2 VCD climatology has been established and the main characteristics from short timescales of one day to interannual variability are presented. Instrumental descriptions and different sources of errors are described in detail. The observed diurnal cycle follows that expected by gas-phase NOx chemistry, as can be shown by the good agreement with a vertically integrated chemical box model, and is modulated by solar radiation. The seasonal evolution departs from the phase of the hours of daylight, indicating the signature of upper stratospheric temperature changes. From the data record (1993–2006) no significant long-term trends in NO2 VCD can be inferred. Comparison of the ground-based data sets with nadir-viewing satellite spectrometers shows excellent agreement for SCIAMACHY with differences between both datasets of 1.1%. GOME displays unrealistic features with the largest discrepancies during summer. The ground-based data are compared with long-term output of the SLIMCAT 3-D chemical transport model (CTM). The basic model, forced by ECMWF (ERA-40) analyses, captures the observed NO2 annual cycle but significantly underestimates the spring/summer maximum (by 12% at sunset and up to 25% at sunrise). In a model run which uses assimilation of satellite CH4 profiles to constrain the model long-lived tracers the agreement is significantly improved. This improvement in modelled column NO2 is due to better modelled NOy profiles and points to transport errors in the ECMWF ERA-40 reanalyses.Routine measurements have been possible thanks to the funding provided by the projects QUILT (EU EVK2-CT2000-0059) SCOUT-O3 (EU 505390-GOCE-CT-2004), TROMPETA (MCyT CGL2004-03669) and is on-going through GEOMON (EU FP6-2005-Global-4- 036677)

Diez años de medidas de NO2 desde el Observatorio de Izaña

Ponencia presentada en: 1er Encuentro sobre Meteorología y Atmósfera de Canarias, celebrado en el Puerto de la Cruz, los días 12,13 y 14 de noviembre de 2003. El encuentro estuvo organizado por el Centro Meteorológico Territorial en Canarias Occidental, con la colaboración del Observatorio Atmosférico de Izaña y del Grupo de Física de la Atmósfera de la Facultad de Física (Universidad de La Laguna)En marzo de 1993 y fruto de un programa de colaboración entre el INM y el INTA se instaló en el Observatorio Atmosférico de lzaña (Tenerife, 28°N, 17ºW) un espectrómetro operando en el visible (430-450 nm). El objetivo principal era obtener la columna total de N02, su dependencia estacional y su relación con el ozono en latitudes subtropicales. En diciembre de 1999 las medidas se incrementaron con la instalación de un nuevo espectrógrafo con array de diodos. Recientemente la estación ha sido incluida como estación complementaria dentro del NOSC. En este trabajo se presentará la climatología del N02 obtenida sobre lzaña, así como la descripción de su onda anual y otras variaciones de periodo corto, así como la variabilidad diaria y su relación con otros procesos químicos y dinámicos que tienen lugar a esas latitudes

Mar project: a project for monitoring Antarctic and subantarctic ozone layer

Ponencia presentada en: 3ª Asamblea Hispano Portuguesa de Geodesia y Geofisica, celebrada en Valencia en 2002The co-ordinated Project presented attempts to increase the limited information existing nowadays about the space-time distribution of NO2, O3, OClO constituents and ultraviolet radiation over Antarctic and sub-Antarctica regions. In the framework of projects financed in previous convocations of the CICYT (PNIA) the installation of three spectrometers in the Argentinean bases of Belgrano, Marambio and Ushuaia was carried out (1994) and an ozosondeador in Belgrano (1999) for the INTA as well as the installation of three radiometers for the INM in the same stations (1999) thanks to the existent agreements of scientific collaboration between INTA and DNA/IAA and INM with DNA/IAA. Both networks of instruments, complementary and co-ordinated, will allow to reach the following objectives: To observe and to characterise the space and temporal evolution so much of the O3, NO2 and OClO like of the ultraviolet radiation in those regions during next years, to carry out a dynamic study of the Antarctic polar vortex in which is analysed as the daily evolution of this it affects at the O3, NO2, OClO and spectral UV radiation giving special attention to populated regions of the South Hemisphere (Ushuaia) and to carry out an exhaustive control of quality of the data obtained by the instruments that assure us to be able to use the measures obtained by the same ones to approach studies of tendencies in next years. Independently of the scientific interest of the previously mentioned objectives, under the atmospheric point of view, this project will provide an unique information to other Spanish groups in Antarctic biology research

Development of a Clinical Prediction Rule to Identify Patients with Neck Pain likely to benefit from Cervical Spine Manipulation and a Range of Motion Exercise

Background: Patients with primary reports of neck pain often present with impairments of mobility, proprioception and motor control within the cervical spine, and these impairments can negatively impact patient outcomes. Cervical spine manipulation (CSM), which involves the use of thrust techniques, has been shown to be effective for some patients presenting with a primary report of neck pain. It would be useful for clinicians to have a decision making tool, such as a clinical prediction rule (CPR), that could accurately identify that subgroup of patients that would respond dramatically to CSM. The purpose of this project was to develop that CPR. Research Design and Methods: A prospective, cohort study of consecutive patients referred to physical therapy with a primary complaint of neck pain. Eligible patients who consented to participate completed a series of self-report measures, and then received a detailed standardized history and physical examination consisting of a variety of factors commonly used to assess patients with neck pain. Regardless of the results of the clinical examination, all patients received a standardized treatment regimen consisting of CSM and exercise. Depending on response to treatment, patients were treated for one to two treatment sessions over approximately 1 week. At the end of their participation in the study, patients were classified as having experienced a successful outcome or not based on a well-accepted patient-reported reference standard of success, the Global Rating of Change Scale. Analysis: Sensitivity, specificity, and positive and negative likelihood ratios were calculated for all potential predictor variables. Univariate techniques and step-wise logistic regression were used to determine the most parsimonious set of variables for prediction of treatment success. Variables retained in the regression model were used to develop a multivariate CPR to identify patients with neck pain likely to benefit from CSM. Results: Eighty-two patients were included in data analysis of which 32 (39%) had achieved a successful outcome. A CPR with 4 variables (symptom duration \u3c 38 days, positive expectation that manipulation will help, difference in cervical rotation range of motion to either side ¡Ý 10 degrees, and pain with spring (PA) testing of the middle cervical spine) was identified. If 3 of the 4 variables (+LR 13.5) were present the chance of experiencing a successful outcome improved from 39% to 90%. Discussion: The CPR should improve decision-making for patients with neck pain by providing the ability to a priori identify patients with neck pain who are likely to benefit from CSM and exercise. However, this is only the first step in the process of developing and testing a CPR as future studies will be necessary to validate the results and should also include long-term follow-up and a comparison group to further examine the predictive value of the variables identified in the CPR

Physician-Delivered Pain Neuroscience Education for Opioid Tapering: A Case Report

We describe the case of a 75-year-old female with chronic low back pain (CLBP), on opioids for more than 15 years. She presented with an acute episode of nausea, vomiting, abdominal pain, and shortness of breath. After a complete work-up, it was concluded that her presenting symptoms were likely due to her high levels of CLBP and high dose opioids. At the time of intervention, her opioid dosage was between 50–90 MME (Morphine milligram equivalent) (Norco 8 × 7.5 mg/day + Fentanyl 12 mcg patch). She was subsequently seen by the physician for seven outpatient internal medicine appointments over nine months and received Pain Neuroscience Education (PNE) in conjunction with monitored tapering of opioids and other medication associated with her CLBP. This case report demonstrates how a physician might deliver PNE as a viable nonpharmacological treatment option for the tapering of long-term opioids for chronic pain
