Pain Interference Is Associated With Psychological Concerns Related to Falls in Community-Dwelling Older Adults: Multisite Observational Study
Authors: Stubbs Brendon , Eggermont Laura H.P. , Patchay Sandhi , Schofield Pat A. 
Published: June 2014

Background
Pain interference and psychological concerns related to falls (PCRF) are pervasive phenomena among community-dwelling older adults, yet their association remains elusive.

Objective
The purpose of this study was to establish whether pain interference is associated with PCRF in community-dwelling older adults.

Design
This was a multisite cross-sectional study.

Method
Two hundred ninety-five community-dwelling older adults (mean age=77.5 years, SD=8.1; 66.4% female) participated in the study. All participants completed the Brief Pain Inventory (BPI) interference subscale, Short Falls Efficacy Scale–International (FES-I), Activities-specific Balance Confidence Scale (ABC), modified version of the Survey of Activities and Fear of Falling in Elderly Scale (mSAFFE), and Consequences of Falling Scale (CoF). Hierarchical multiple regression analysis were conducted. In the first step of the study, sociodemographic and known risk factors for psychological concerns related to falls were inserted into the model, followed by the BPI interference subscale score in the second step.

Results
One hundred sixty-nine participants (57.3%) reported some pain interference. The BPI interference subscale was highly correlated with all PCRF (r&gt;.5, P&lt;.0001). After the adjustment for established risk factors, the BPI interference subscale significantly increased the variance in the Short FES-I (R2 change=13.2%), ABC (R2 change=4.7%), mSAFFE (R2 change=5.0%), and CoF (R2 change=10.0%). Pain interference was a significant and independent predictor in the final model for the Short FES-1 (β=0.455, P&lt;.001), ABC (β=−0.265, P&lt;.001), mSAFFE (β=0.276, P&lt;.001), and CoF (β=0.390, P&lt;.001).

Limitations
The study was cross-sectional.

Conclusions
Pain interference is an important contributing factor in each of the psychological concerns related to falls. Pain interference had the strongest impact on reducing falls efficacy and increasing older adults' concerns about the consequences of falling.

Object
Traditionally, hemisacrectomy and internal hemipelvectomy procedures have required both an anterior and a posterior approach. A posterior-only approach has the potential to complete an en bloc tumor resection and spinopelvic reconstruction while reducing surgical morbidity.

Methods
The authors describe 3 cases in which en bloc resection of the hemisacrum and ilium and subsequent lumbopelvic and pelvic ring reconstruction were performed from a posterior-only approach. Two more traditional anterior and posterior staged procedures are also included for comparison.

Results
In all 3 cases, an oncologically appropriate surgery and spinopelvic reconstruction were performed through a posterior-only approach.

Conclusions
The advantage of a midline posterior approach is the ability to perform a lumbosacral reconstruction, necessary in cases in which the S-1 body is iatrogenically disrupted during tumor resection.

Object
Cervical spondylosis that causes upper-extremity muscle atrophy without gait disturbance is called cervical spondylotic amyotrophy (CSA). The distal type of CSA is characterized by weakness of the hand muscles. In this retrospective analysis, the authors describe the clinical features of the distal type of CSA and evaluate the results of surgical treatment.

Methods
The authors performed a retrospective review of 17 consecutive cases involving 16 men and 1 woman (mean age 56.3 years) who underwent surgical treatment for the distal type of CSA. The condition was diagnosed on the basis of cervical spondylosis in the presence of muscle impairment of the upper extremity (intrinsic muscle and/or finger extension muscles) without gait disturbance, and the presence of a compressive lesion involving the anterior horn of the spinal cord, the nerve root at the foramen, or both sites as seen on axial and sagittal views of MRI or CT myelography. The authors assessed spinal cord or nerve root impingement by MRI or CT myelography and evaluated surgical outcomes.

Results
The preoperative duration of symptoms averaged 11.8 months. There were 14 patients with impingement of the anterior horn of the spinal cord and 3 patients with both anterior horn and nerve root impingement. Twelve patients were treated with laminoplasty (plus foraminotomy in 1 case), 3 patients were treated with anterior cervical discectomy and fusion, and 2 patients were treated with posterior spinal fixation. The mean manual muscle testing grade was 2.4 (range 1–4) preoperatively and 3.4 (range 1–5) postoperatively. The surgical results were excellent in 7 patients, good in 2, and fair in 8.

Conclusions
Most of the patients in this series of cases of the distal type of CSA suffered from impingement of the anterior horn of the spinal cord, and surgical outcome was fair in about half of the cases.
Thirty-day outcomes of cerebrospinal fluid shunt surgery: data from the National Surgical Quality Improvement Program-Pediatrics
Authors: Piatt Joseph H. 
Published: June 2014

Object
Cerebrospinal fluid shunts are the mainstay of the treatment of hydrocephalus. In past studies, outcomes of shunt surgery have been analyzed based on follow-up of 1 year or longer. The goal of the current study is to characterize 30-day shunt outcomes, to identify clinical risk factors for shunt infection and failure, and to develop statistical models that might be used for risk stratification.

Methods
Data for 2012 were obtained from the National Surgical Quality Improvement Program-Pediatrics (NSQIP-P) of the American College of Surgeons. Files with index surgical procedures for insertion or revision of a CSF shunt composed the study set. Returns to the operating room within 30 days for shunt infection and for shunt failure without infection were the study end points. Associations with a large number of potential clinical risk factors were analyzed on a univariate basis. Logistic regression was used for multivariate analysis.

Results
There were 1790 index surgical procedures analyzed. The overall rates of shunt infection and shunt failure without infection were 2.0% and 11.5%, respectively. Male sex, steroid use in the preceding 30 days, and nutritional support at the time of surgery were risk factors for shunt infection. Cardiac disease was a risk factor for shunt failure without infection, and initial shunt insertion, admission during the second quarter, and neuromuscular disease appeared to be protective. There was a weak association of increasing age with shunt failure without infection. Models based on these factors accounted for no more than 6% of observed variance. Construction of stable statistical models with internal validity for risk adjustment proved impossible.

Conclusions
The precision of the NSQIP-P dataset has allowed identification of risk factors for shunt infection and for shunt failure without infection that have not been documented previously. Thirty-day shunt outcomes may be useful quality metrics, possibly even without risk adjustment. Whether important variation in 30-day outcomes exists among institutions or among neurosurgeons is yet unknown.
La gamelle ou la cantine ? Formes et enjeux de la restauration dans les témoignages écrits ouvriers depuis 1945
Authors: Le Port Éliane 
Published: June 2014

Les pratiques alimentaires sur le lieu de travail occupent une place particulière dans les témoignages écrits ouvriers de type autobiographique. L’examen des comportements et des stratégies alimentaires renseigne à la fois sur les lieux et les temps de repas et de pause, sur les types de nourriture ainsi que sur les sociabilités à l’œuvre. L’atelier apparaît comme un lieu important de consommation, notamment dans les récits publiés dans l’immédiat après-guerre. Si plusieurs témoignages révèlent des habitudes ancrées, une fidélité au repas sur le lieu du travail, répondant au besoin de recréer un espace familier, d’autres ouvriers préfèrent les espaces extérieurs à l’usine ou au chantier et « sortent du travail », dans les restaurants ouvriers, au café, mettant à distance le lieu du travail. Qu’elles soient ordinaires ou festives, les pratiques alimentaires s’inscrivent dans les rythmes quotidiens du travail et les témoignages révèlent des liens complexes entre des temps a priori différenciés, celui de la production et celui du repas. Derrière la grande variété de comportements, les témoignages laissent voir une forte socialisation de l’acte alimentaire : se mettre à table au travail demeure le plus souvent un temps partagé. En cela le repas représente une des pierres de touche des sociabilités ouvrières que traduit l’écriture.

Résumé Parmi les outils de l’investisseur, la formule des flux actualisés (discounted cash flow, ou DCF) occupe une place capitale. Elle dérive la valeur d’une chose des flux d’argent que celle-ci produira dans le futur, en les réduisant d’un facteur d’autant plus grand qu’ils sont éloignés dans le temps. Cet article examine les fondements de cette formule et identifie trois configurations – des ensembles de problèmes, d’acteurs et d’objets – dans son développement. Solution à un problème pratique de valorisation et de gestion des forêts dans les calculs de forestiers allemands au milieu du XIXe siècle, puis expression d’une définition universelle de la valeur dans la théorie économique au début du XXe siècle, la formule devient, à partir des années 1950, un instrument de gouvernement des investissements et se répand dans la pratique des entreprises. L’article met en lumière le rôle joué par l’État, des économistes et des consultants dans la constitution de cette formule comme principal outil d’évaluation des investissements. Il décrit les effets que la formule DCF induit sur les objets auxquels elle se voit appliquer et la figure de l’utilisateur – un « manager-investisseur » – qu’elle dessine et équipe.
Estimates of the power per mode number of broadband ULF waves at geosynchronous orbit
Authors: Sarris T. E. 
Published: June 2014

AbstractIn studies of radial diffusion processes in the magnetosphere it is well known that ultralow frequency (ULF) waves of frequency mωd can resonantly interact with particles of drift frequency ωd, where m is the waves' azimuthal mode number. Due to difficulties in estimating m, an oversimplifying assumption is often made in simulations, namely that all ULF wave power is located at a single mode number. In this paper a technique is presented for extracting information on the distribution of ULF power in a range of azimuthal mode numbers. As a first step, the cross power and phase differences between time series from azimuthally aligned magnetometers are calculated. Subsequently, through integrating the ULF power at particular ranges of phase differences that correspond to particular mode numbers, estimates of the fraction of the total power at each phase difference range or mode number are provided. Albeit entwined with many ambiguities, this technique offers critical information that is currently missing when estimating radial diffusion of energetic particles. As proof‐of‐concept, the technique is first tested successfully for a well‐studied case of narrowband ULF Field Line Resonances (FLR) for which the mode number was calculated simultaneously through ground‐based and space measurements. Subsequently, the technique is demonstrated for the broadband ULF waves that accompanied the 2003 “Halloween” magnetospheric storms. The temporal evolution of power at each mode number gives insight into the evolution of ULF waves during a storm as well as more accurate characterization of broadband ULF waves that can be used in radial diffusion simulations.
Seasonal snowpack characteristics influence soil temperature and water content at multiple scales in interior western U.S. mountain ecosystems
Authors: Maurer Gregory E. , Bowling David R. 
Published: June 2014

AbstractMountain snowpacks directly and indirectly influence soil temperature (Tsoil) and soil water content (θ). Vegetation, soil organisms, and associated biogeochemical processes certainly respond to snowpack‐related variability in the soil biophysical environment, but there is currently a poor understanding of how snow‐soil interactions vary in time and across the mountain landscape. Using data from a network of automated snowpack monitoring stations in the interior western U.S., we quantified seasonal and landscape patterns in Tsoil and θ, and their dependence on snowpack characteristics over an eleven year period. Elevation gradients in Tsoil were absent beneath winter snowpacks, despite large gradients in air temperature (Tair). Winter Tsoil was warmer and less variable than Tair, but interannual and across‐site variations in Tsoil were likely large enough to impact biogeochemical processes. Winter θ varied between years and across sites, but during a given winter at a site it changed little between the start of snowpack accumulation and the initiation of spring snowmelt. Winter Tsoil and θ were both higher when early winter snow accumulation was greater. Summer θ was lower when summer Tair was high. Depending on the site and the year examined, summer θ was higher when there was greater summer precipitation, a larger snowpack, later snowpack melt, or a combination of these factors. We found that snowpack‐related variability in the soil environment was of sufficient magnitude to influence biogeochemical processes in snow‐dominated ecosystems.
Snowpack regimes of the Western United States
Authors: Trujillo Ernesto , Molotch Noah P. 
Published: June 2014

AbstractSnow accumulation and melt patterns play a significant role in the water, energy, carbon, and nutrient cycles in the montane environments of the Western United States. Recent studies have illustrated that changes in the snow/rainfall apportionments and snow accumulation and melt patterns may occur as a consequence of changes in climate in the region. In order to understand how these changes may affect the snow regimes of the region, the current characteristics of the snow accumulation and melt patterns must be identified. Here we characterize the snow water equivalent (SWE) curve formed by the daily SWE values at 766 snow pillow stations in the Western United States, focusing on several metrics of the yearly SWE curves and the relationships between the different metrics. The metrics are the initial snow accumulation and snow disappearance dates, the peak snow accumulation and date of peak, the length of the snow accumulation season, the length of the snowmelt season, and the snow accumulation and snowmelt slopes. Three snow regimes emerge from these results: a maritime, an intermountain, and a continental regime. The maritime regime is characterized by higher maximum snow accumulations reaching 300 cm and shorter accumulation periods of less than 220 days. Conversely, the continental regime is characterized by lower maximum accumulations below 200 cm and longer accumulation periods reaching over 260 days. The intermountain regime lies in between. The regions that show the characteristics of the maritime regime include the Cascade Mountains, the Klamath Mountains, and the Sierra Nevada Mountains. The intermountain regime includes the Eastern Cascades slopes and foothills, the Blue Mountains, Northern and Central basins and ranges, the Columbia Mountains/Northern Rockies, the Idaho Batholith, and the Canadian Rockies. Lastly, the continental regime includes the Middle and Southern Rockies, and the Wasatch and Uinta Mountains. The implications of snow regime classification are discussed in the context of possible changes in accumulation and melt patterns associated with regional warming.

Published: June 2014

AbstractThe influence of Madden‐Julian Oscillation (MJO) on the rainfall distribution of Southeast Asia is studied using TRMM satellite‐derived rainfall and rain gauge data. It is shown that convectively active (suppressed) phases of MJO can increase (decrease) the probability of extreme rain events over the land regions by about 30–50% (20–25%) during November–March season. The influence of MJO on localized rainfall extremes are also observed both in rainfall intensity and duration. The Met Office Global Seasonal forecasting system seasonal forecasting system is shown to reproduce the MJO influence on rainfall distribution well despite the model biases over land. Skills scores for forecasting 90th percentile extreme rainfall shows significant skills for convective phases. This study demonstrates the feasibility of deriving probabilistic forecasts of extreme rainfall at medium range.
Water permeability in hydrate‐bearing sediments: A pore‐scale study
Authors: Dai Sheng , Seol Yongkoo 
Published: June 2014

AbstractPermeability is a critical parameter governing methane flux and fluid flow in hydrate‐bearing sediments; however, limited valid data are available due to experimental challenges. Here we investigate the relationship between apparent water permeability (k′) and hydrate saturation (Sh), accounting for hydrate pore‐scale growth habit and meso‐scale heterogeneity. Results from capillary tube models rely on cross‐sectional tube shapes and hydrate pore habits, thus are appropriate only for sediments with uniform hydrate distribution and known hydrate pore character. Given our pore network modeling results showing that accumulating hydrate in sediments decreases sediment porosity and increases hydraulic tortuosity, we propose a modified Kozeny‐Carman model to characterize water permeability in hydrate‐bearing sediments. This model agrees well with experimental results and can be easily implemented in reservoir simulators with no empirical variables other than Sh. Results are also relevant to flow through other natural sediments that undergo diagenesis, salt precipitation, or bio‐clogging.
Extracting trace amount of terbinafine hydrochloride in biological fluids and wastewater samples using solid‐phase‐extraction based on magnetic nanoparticles followed by HPLC‐UV analysis

Published: June 2014

ABSTRACTIn this paper, the application of sodium dodecylsulfate‐coated Fe3O4 nanoparticles as an adsorbent was evaluated for the extraction and preconcentration of trace amounts of terbinafine hydrochloride in biological fluids before its determination by high‐performance liquid chromatography with ultraviolet detection. Effects of various parameters on the extraction efficiency such as pH of solution, amount of sodium dodecylsulfate surfactant, extraction time, and desorption conditions were studied and optimized. Under the optimal conditions, the calibration curve was linear in the range of 2.5 to 500 µg L−1 with the correlation coefficient of 0.9998. Moreover, the calibration graphs were linear in the range of 5 to 500 µg L−1 (seven standards) for both urine and plasma samples and the limits of detection were found to be 0.3, 0.7, and 1.5 µg L−1in aqueous, urine, and plasma samples, respectively. Also, the percent of relative standard deviation (RSD%) based on three replicate determinations was in the range of 0.9% to 6.8%. Finally, the proposed method was successfully applied for the extraction of terbinafine from real samples, and satisfactory results were obtained. © 2014 Curtin University of Technology and John Wiley & Sons, Ltd.
Study on synthesis and photochemical behavior of carbamate photobase generators for fluorescence imaging
Authors: Liu Lanlan , Guo Jinbao , Wei Jie 
Published: June 2014

ABSTRACTA fluorescence imaging system is designed based on the photodecomposition of photobase generators embedded in polyvinyl butyral (PVB) matrix. These photobase generators were synthesized with propyl and phenethyl units served as leaving groups, and phthalimido, succinimido, di‐2‐thienyl ketoximino, and benzophenoneoximino units acted as photosensitive species, respectively. The influences of the two leaving groups and four photosensitive species on the photochemical behavior were investigated in detail. The results demonstrate that the photochemical properties of these photobase generators depend on the photosensitive species other than the leaving groups. And further study shows that succinimido propylcarbamate (SPrC) exhibits the best thermal stability and relatively quick rate of photodecomposition among all the photobase generators. Therefore, a PVB film embedded with SPrC is used as a fluorescence imaging material. The patterned fluorescence image obtained from the fluorescamine‐treated irradiated PVB film showed bright green fluorescence, which provides potential application for optical storage or color electronic displays. © 2014 Wiley Periodicals, Inc.

Technology and Technicity: A Critical Analysis of Some Contemporary Models of Borderline Personality Disorder
Authors: Cammell Paul 
Published: June 2014

AbstractIn this article I discuss the philosophical writings of Bernard Stiegler, Jacques Derrida and Michel Foucault concerning the concept of technology. Technology and “technicity” can be seen to be essential elements of any current culture not only in relation to material practices, but also in terms of how cultures understand and represent themselves as a collective of “individuals”. I argue that our current technological culture plays a significant role in determining how emotional problems and forms of mental illness are constituted or constructed. In particular, I focus on the widespread adoption of the concept of “borderline personality disorder”. I critically analyze how contemporary models of the treatment of this disorder form part of a contemporary cultural context in which the diagnosis and recipients of the diagnosis are actively constructed or constituted by practitioners of these models, rather than disinterestedly studied and treated by them in an objective or naturalistic sense. I draw conclusions about how a greater awareness of our “technological” cultural context can influence or improve the orientation of the psychotherapist. Copyright © 2014 John Wiley & Sons, Ltd.

Published: June 2014

AbstractA new cresyl violet‐based fluorescent off–on probe has been developed through a one‐step synthesis for the detection of nitroreductase (NTR) and hypoxia. The detection mechanism is based on the NTR‐catalyzed reduction of the probe to cresyl violet, accompanied with a large fluorescence enhancement at a long wavelength of 625 nm. The probe can detect NTR in aqueous solution with high selectivity and sensitivity, and the detection limit is 1 ng mL−1 NTR. Most importantly, the probe has been successfully used to image not only NTR and hypoxia in living cells, but also the distribution of NTR in zebrafish in vivo.
