Personal Strategic Plan Development: Getting Ready for Changes in Our Professional and Personal Lives
Authors: Hinojosa Jim 
Published: May 2012

Abstract
Daily challenges for occupational therapists and occupational therapy assistants are changing work environments and the desire to address the needs of their clients. This article highlights the need for occupational therapy practitioners to create personal strategic plans to prepare for their rapidly changing futures. Although AOTA’s Centennial Vision responds to the profession's future, practitioners must focus on their personal and professional roles and responsibilities. They also must engage in individual strategic planning. Sound individual strategic planning provides a means for practitioners to merge their fantasized views of occupational therapy with the reality of today's practice.
Current Occupational Therapy Publications in Home Health: A Scoping Review
Authors: Craig Daniel G. 
Published: May 2012

Abstract
PURPOSE. Recently, home health services have been a topic of increasing interest. Occupational therapy practice and utilization patterns in home care have not been the subject of recent research.
METHOD. I examined 65 publications addressing current occupational therapy practice in U.S. home health. Articles were analyzed to uncover factors influencing occupational therapy utilization and practice.
RESULTS. Results indicate that research has looked at a variety of typologies and efficacy measures for occupational therapy in home care. However, occupational therapy utilization and practice patterns in home health do not appear to be entirely consistent with research. I identify factors explaining this inconsistency and make research and practice recommendations.
CONCLUSION. Results suggest that system challenges limit the utilization and practice of occupational therapy to deliver expected outcomes in home health practice.

Authors: Stav Wendy B. , Hallenen Theresa , Lane Jennifer , Arbesman Marian 
Published: May 2012

Abstract
We conducted this systematic review, one of four related to productive aging, to explore the existing evidence for the health benefits of engagement in occupations and activities among older adults. The review incorporates the breadth of areas of occupation in which older adults engage and the range of health benefits derived from that engagement. The results of this review demonstrate the multidisciplinary appreciation for occupational engagement and associated well-being and elucidate the health effects of engagement in a wide variety of occupations and activities. Additionally, the results of this systematic review support occupational therapy’s historical ideologies and core philosophies linking occupational engagement to improved health and well-being. The findings suggest an increasing role for occupational therapy service delivery in community-based health promotion and prevention efforts to meet the everyday activity and health needs of the growing older adult population.
Research Focused on Children and Youth
Authors: Hilton Claudia List , Smith Diane L. 
Published: May 2012

Abstract
We reviewed 22 articles on children and youth published in 2011 in the American Journal of Occupational Therapy and organized the articles by level of research and research type according to a framework adapted from the International Classification of Functioning, Disability and Health (ICF; World Health Organization, 2007). The largest percentage of articles described intervention effectiveness studies classified as Level III or IV. The bulk focused on the Body Function/Body Structure construct of the ICF, but as a whole the studies addressed all the constructs except Biomedical Molecular/Cellular. Rigor remains a concern, although laudable efforts have been made to increase strength of the evidence. Longitudinal, efficacy, and qualitative studies, as well as studies examining adolescents and the transition to adulthood, were absent from articles in this review and are important areas for future investigation. Several studies explicitly addressed intervention fidelity, an imperative in evidence-based research needed to move the profession toward the Centennial Vision.
Systematic Review of the Effect of Home Modification and Fall Prevention Programs on Falls and the Performance of Community-Dwelling Older Adults
Authors: Chase Carla A. , Mann Kathryn , Wasek Sarah , Arbesman Marian 
Published: May 2012

Abstract
This systematic review explored the impact of fall prevention programs and home modifications on falls and the performance of community-dwelling older adults. It was conducted as part of the American Occupational Therapy Association’s Evidence-Based Practice Project. Thirty-three articles were analyzed and synthesized. The strongest results were found for multifactorial programs that included home evaluations and home modifications, physical activity or exercise, education, vision and medication checks, or assistive technology to prevent falls. Positive outcomes included a decreased rate of functional decline, a decrease in fear of falling, and an increase in physical factors such as balance and strength. The strength of the evidence for physical activity and home modification programs provided individually was moderate. Implications for practice, education, and research are also discussed.
Analysis of Bone Formation on Porous and Calcium Phosphate-Coated Acetabular Cups: A Randomised Clinical [18F]Fluoride Pet Study
Authors: Ullmark Gösta , Sörensen Jens , Nilsson Olle 
Published: May 2012

We present a study using Fluoride-Positron Emission Tomography (F-PET/CT) to analyse new bone formation in periacetabular bone adjacent to press fit cups following THA. In 16 THA (8 patients) with bilateral hip osteoarthritis simultaneous bilateral total hip arthroplasty (THA) was performed, employing electrochemically applied calcium phosphate coated (HA) cups or porous-coated (PC) cups allocated at random to compare the two sides. A reference group of 13 individuals with a normal healthy hip was used to determine ‘normal’ bone metabolism. [18F]fluoride -PET/CT was used to analyze bone formation adjacent to the cups 1 week, 4 months and 12 months after surgery. Clinical and radiographic evaluation was performed preoperatively, postoperatively and at 2 years. Bone forming activity had a mean of 5.71, 4.69 and 3.47 SUV around the HA- and 5.04, 4.80 and 3.50 SUV around the PC-cups at 1 week, 4 months and 12 months respectively. Normal bone metabolism was 3.68 SUV. After 1 year activity had declined to normal levels for both groups. The clinical results were good in all cases. HA coating resulted in higher uptake indicating higher bone forming activity after 1 week. F-PET/CT is a valuable tool to analyse bone formation and secondary stabilisation of an acetabular cup.

Published: May 2012

This study aimed to examine the association between hip joint effusion volume and osteonecrosis of the femoral head (ONFH) using the Association Research Circulation Osseous (ARCO) classification. Patients (n = 403) who were diagnosed with ONFH were enrolled between February 2005 and December 2008. Only patients (n = 109) with complete clinical and imaging data and at early to mid ARCO stage (I - III) were eligible for further analysis, including 94 males and 15 females. All the included patients had hip joint radiographic examinations (anteroposterior and frog-leg views) and magnetic resonance imaging scans (axial and coronal views). Out of 109 patients included in this study, 185 hip joints were involved (unilateral disease in 33 patients and bilateral diseases in 76 patients). The patients had a mean age of 39 ± 11 years (range, 13–70). All the affected hip joints exhibited effusion, classified as grade 1 (n = 70, 37.8%), grade 2 (n = 62, 33.5%), and grade 3 (n = 53, 28.7%). The volume of joint effusion varied significantly among stage I, II, and III (X2 = 29.210, P < 0.05). The effusion volume did not differ significantly among stage IIA, IIB, and IIC (X2 = 0.103, P > 0.05), whereas it differed significantly among stage IIIA, IIIB, and IIIC (X2 =11.556, P < 0.05). The volume of hip joint effusion was associated with the ARCO stage, and increased over the staging.

Published: April 2012

AbstractSome oligo‐ or polyamides containing several hydroxyl groups were synthesized in order to obtain new water‐soluble compounds with a high affinity for polar materials as wood, paper, and natural fibers. The interest for the synthetic procedures is the use of renewable sources as starting compounds. In fact natural compounds or their derivatives, as l‐tartaric acid, d(+)‐glucaric acid and α,α‐trehaluronic acid, were used as dicarboxylic acids in the polycondensation reactions, in order to obtain several functionalized oligoamides. All the compounds obtained in this study were characterized through FTIR and NMR spectroscopy. The oligoamides, water‐soluble and not provided with high‐molecular weights, were tested as wood consolidants. Physical properties like hygroscopicity of stabilized wood, volume shrinkage, density, and basic density were evaluated on the treated samples and compared with those obtained in the same conditions for an untreated archeological sample and a recent wood sample. © 2012 Wiley Periodicals, Inc.

Published: April 2012

AbstractA modified polyethylene coated polypropylene (PE‐coated‐PP) non‐woven fabric was prepared by surface coating with a constant layer of thickness (25 μm) of a mixture of an aqueous solution of carboxymethyl cellulose (CMC) and different concentrations of acrylic acid (AAc). Radiation curing of the coated layer was accomplished by electron beam irradiation with a constant dose of 30 kGy. The value of coating percent was calculated in terms of difference in weight. Properties related to hydrophilicty, such as swelling and water uptake %, were investigated by difference in weight of dry and wet samples after several washing cycles. Weight loss, before and after several washing cycles, was monitored. The effect of AAc concentration on the weight loss % of the modified fabric was studied. Moreover, the swelling in different solvents, dilute acid and base, was investigated. The structure of the modified fabric was characterized by Fourier transform infrared spectroscopy and scanning electron microscope in order to examine the compatibility between the coated layer and fabric. Mechanical properties in terms of tensile strength and elongation at break were studied. The efficiency of the uptake of this modified fabric toward basic, reactive dyes, and metal ions such as Cu2+, Ni2+, and Co2+ was measured by UV spectrophotometer and energy dispersive X‐ray. The results obtained show good efficiency of these modified fabrics toward heavy metal ions and dyes. © 2012 Wiley Periodicals, Inc. J. Appl. Polym. Sci., 2013

Published: April 2012

AbstractA novel polyhedral oligomeric octa(propargylaminophenyl)silsesquioxane (OPAPS, (SiO1.5C6H4NHCH2CCH)8) was prepared from octa(aminophenyl)silsesquioxane and propargyl bromide. The chemical structure of OPAPS was characterized by Fourier transform infrared spectroscopy (FTIR), nuclear magnetic resonance, X‐ray diffraction (XRD), high‐performance liquid chromatography, gel permeation chromatography, differential scanning calorimetry, and thermal gravimetric analysis (TGA). The structure of the thermally cured polymer of OPAPS was characterized by FTIR, XRD, and TGA. It had good thermal stability. TGA demonstrated that the thermal decomposition temperatures (Td5) of the cured OPAPS polymer in nitrogen and air were 455.6 and 458.8°C, respectively. The thermal curing reaction kinetics of OPAPS were studied and some kinetic parameters were obtained. © 2012 Wiley Periodicals, Inc. J. Appl. Polym. Sci., 2013

Published: April 2012

AbstractThe aim of this work is to study the use of an ionic liquid (IL) as surfactant in emulsion polymerization reactions and to evaluate its effect when these reactions are heated under microwave irradiation. The IL 1‐n‐dodecyl‐3‐methylimidazolium chloride was chosen to replace the surfactant dodecyltrimethylammonium bromide (DTAB) in methyl methacrylate emulsion polymerizations. The conversion evolutions and the final average diameter of polymeric particles were quite similar for reactions using the surfactant DTAB or the IL, showing that the IL acted efficiently as surfactant in emulsion polymerizations. Comparing the polymerization reactions performed under microwave irradiation and conventional heating, reaction rate enhancements were obtained for both DTAB and IL. Using a pulsed scheme, under high‐power microwave irradiation, slightly higher reaction rates and molecular weights were obtained in reactions using IL, in comparison with surfactant DTAB, indicating the existence of some specific effects linked to IL–microwaves interaction. © 2012 Wiley Periodicals, Inc.

A comprehensive study on the size exclusion chromatography of kappa‐carrageenan for the identification of after‐peaks
Authors: Şen Murat , Yolaçan Burcu , Güven Olgun 
Published: April 2012

AbstractAqueous size exclusion chromatography (SEC) of polysaccharides in general and carrageenans in particular is complicated by a number of factors. The chromatograms of carrageenans which are sulfated anionic natural polymers contain a number of after‐peaks depending on the occlusion, adsorption, or association of various ionic species either naturally present or evolved during their processing. A systematic SEC analysis of after‐peaks appearing in the chromatograms was made to identify the species responsible for their formation. The five after‐peaks constantly appearing in the aqueous (0.1M NaNO3) SEC of kappa‐carrageenan are attributed to sulfate, chloride, and nitrate anions whereas the first three and the fourth are due to divalent cations, mostly, and the fifth appears to result from the unknown impurities. © 2012 Wiley Periodicals, Inc.

Published: April 2012

AbstractCarbon nanotubes (CNTs) were annealed at high temperature under vacuum, followed by a chemical treatment using acids and ethylenediamine. The presence of acid and amine chemical groups on CNT surface was confirmed by infrared spectra. The amount of iron remaining in the CNTs after the treatments was evaluated by thermogravimetry and by energy dispersion spectroscopy. The crystalline property of CNTs was evaluated by Raman spectroscopy, showing that the acid treatment performed after the thermal treatment did not damage the nanotubes walls. Micrographs showed that the most dispersed CNTs were obtained after the amine functionalization step. The curing process of the neat resin and composites was studied by Raman and Luminescence spectroscopies and both techniques showed similar results. The presence of CNTs, functionalized or not, increased the cure degree of the epoxy resin when the same cure time was used in the comparison. Nanocomposites synthesized with annealed CNT and acid‐treated CNT had cure rates considerably higher at the beginning of the reaction. The difference in the cure rate was explained by means of the sample's homogeneity and the presence of chemical groups. © 2012 Wiley Periodicals, Inc. J. Appl. Polym. Sci., 2013
Thiophene‐based copolymers synthesized by electropolymerization for application as hole transport layer in organic solar cells

Published: April 2012

AbstractElectrically conducting thiophene‐based copolymers were synthesized by electropolymerization. The potential range used has a strong influence on the film structure and properties. The extent of oxidation of the copolymers was determined from the ratio of the oxidation to reduction charge, Qox/Qred. The use of wide potential range leads to reduced films, whereas the narrow range leads to partially oxidized films. The copolymers exhibit a characteristic band in UV–vis spectra at ∼ 410 nm, which shifts to higher wavelengths for the more doped material. The electrical conductivity of the copolymers was correlated to their morphology and their structure. The copolymer with higher conductivity is partially reduced, has compact morphology and higher ratio of quinoid to benzenoid rings. The energy gap of the copolymers is reversely proportional to their electrical conductivity. The optical and electrical properties of the copolymers make them very well suited for use as hole transport layers (HTL) in organic opto‐electronic devices. We prepared polymer : fullerene solar cells with copolymer HTLs. The solar cell performance was tested with very encouraging initial results. © 2012 Wiley Periodicals, Inc. J. Appl. Polym. Sci., 2013

AbstractThe aim of this study was to determine whether the exposure to either single or multiple radio‐frequency (RF) radiation frequencies could induce oxidative stress in cell cultures. Exposures of human MCF10A mammary epithelial cells to either a single frequency (837 MHz alone or 1950 MHz alone) or multiple frequencies (837 and 1950 MHz) were conducted at specific absorption rate (SAR) values of 4 W/kg for 2 h. During the exposure period, the temperature in the exposure chamber was maintained isothermally. Intracellular levels of reactive oxygen species (ROS), the antioxidant enzyme activity of superoxide dismutase (SOD), and the ratio of reduced/oxidized glutathione (GSH/GSSG) showed no statistically significant alterations as the result of either single or multiple RF radiation exposures. In contrast, ionizing radiation‐exposed cells, used as a positive control, showed evident changes in all measured biological endpoints. These results indicate that single or multiple RF radiation exposure did not elicit oxidative stress in MCF10A cells under our exposure conditions.

Published: April 2012

ABSTRACTThis article describes a copper‐catalyzed aza‐Henry reaction. Copper complexes of camphor‐derived aminopyridines catalyze the addition of nitromethane to N‐(2‐pyridyl)sulfonyl aldimines to give the corresponding β‐nitrosulfonamides with good yields and variable enantiomeric excesses (up to 83%). An example of transformation of these compounds into N‐(2‐pyridyl)sulfonyl‐α‐amino acids and deprotection of the sulfonamide with Mg–MeOH is provided.

Published: April 2012

ABSTRACTIsophthalic and terephthalic acid monoesters of cyclic nigerosyl‐(1→6)‐nigerose (CNN), a cyclic tetrasaccharide composed of four d‐glucopyranosyl residues connected by alternating α‐1,3‐ and α‐1,6‐linkages, were synthesized as novel chiral supramolecular sensitizers for enantiodifferentiating photoisomerization of (Z)‐cyclooctene (1Z) to planar chiral (E)‐isomer (1E). Despite the saucer‐shaped shallow cavity of CNN that does not immediately guarantee strong ground‐state interactions with 1Z, the sensitizer‐appended CNNs afforded optically active 1E in such enantiomeric excesses that are much improved than those obtained with an α‐cyclodextrin analog and comparable with those obtained with a β‐cyclodextrin analog. Interestingly, the enantiomeric excess values obtained were a critical function of temperature and solvent to show an inversion of the product chirality by changing the environmental variants. Nevertheless, all of the differential activation parameters calculated from the temperature‐dependent enantiomeric excesses gave an excellent compensatory enthalpy–entropy relationship, indicating an operation of a single enantiodifferentiating mechanism in the present chiral photosensitization with modified CNNs.

ABSTRACTThis work describes the atropisomeric relationships of 3‐methyl‐5‐(3‐methyl‐5‐phenyl‐1H‐pyrazol‐1‐yl)‐1‐phenyl‐1H‐pyrazol‐4‐amine (2d), which belongs to series 4‐aminobipyrazole derivatives designed as anti‐inflammatory agents. The 1H nuclear magnetic resonance spectra obtained in the presence of a chiral lanthanide shift salt associated to chiral high‐performance liquid chromatography analysis, X‐ray diffraction, and molecular modeling tools confirmed that ortho bis‐functionalized bipyrazole 2d exists as a mixture of aR,aS‐atropisomers. These results provide useful information to understand the pharmacological profile of this derivative and of other 4‐aminobipyrazole analogs. Chirality 24:463–470, 2012. © 2012 Wiley Periodicals, Inc.
