Functional Movement Screen as a Predictor of Occupational Injury Among Denver Firefighters
Shore, Erin,Dally, Miranda,Brooks, Shawn,Ostendorf, Danielle,Newman, Madeline,Newman, Lee Occupational Safety and Health Research Institute 2020 Safety and health at work Vol.11 No.3
Background: The Functional Movement Screen (FMS<sup>TM</sup>) is a screening tool used to assess an individual's ability to perform fundamental movements that are necessary to do physically active tasks. The purpose of this study was to assess the ability of FMS to predict occupational injury among Denver Fire Department firefighters. Method: FMS tests were administered from 2012 to 2016. Claim status was defined as any claim occurrence vs. no claim and an overexertion vs. no claim/other claim within 1 year of the FMS. To assess associations between FMS score and claim status, FMS scores were dichotomized into ≤ 14 and > 14. Age-adjusted odds ratios were calculated using logistic regression. Sensitivities and specificities of FMS predicting claims at various FMS score cut points, ranging from 10 to 20 were tested. Results: Of 581 firefighters (mean ± SD, age 38 ± 9.8 y) who completed FMS between February 2015 and March 2018, 188 (32.4%) filed a WC claim in the study time frame. Seventy-two of those (38.3%) were categorized as overexertion claims. There was no association between FMS score and claim status [odds ratio (OR) = 1.27, 95% confidence interval (CI): 0.88 - 1.83] and overexertion claim vs. no claim/other claim (OR = 1.33, 95% CI: 0.81 - 2.21). There was no optimal cutoff for FMS in predicting a WC claim. Conclusions: Although the FMS has been predictive of injuries in other populations, among this sample of firefighters, it was not predictive of a future WC claim.

Context – The luxury market has, in recent years, continued to grow substantially and has been helped by the boost and growing appetite of emerging economies. Indeed Luxury is one of the fastest-growing brand sectors (Berthon et al., 2009). Due to the high supply and vast choice available in the various segments including luxury goods, consumers nowadays are no longer loyal to one single brand but they prefer to choose and have a demanding and critical attitude towards exactly what they want to purchase (Okonkwo, 2007). By looking at the recent transformations in the globalised and ever more connected world, we can see that the luxury market has expanded, from a limited availability to a select group of consumers (the few who could afford the price), to a market with more people of moderate means having access to the product and all its inherent passion (Okonkwo, 2009, Silverstein and Fiske, 2003). However, the concept of luxury, although defined widely (Dubois et al., 2001 and Vickers and Renand, 2003, among the most popular definitions), does not appear to have a consensus on the definition (Choi, 2003; Wiedmann, Hennigs and Siebels, 2009). It is crucial to understand the reasons why consumers buy luxury (Kapferer and Bastien, 2009; Keller, 2009) and the perception process (Tynan, McKechnie and Chhuon, 2010; Wiedmann, Hennigs and Siebels, 2007). Learning how consumers process their knowledge from the attributes of a luxury brand and attribute them a meaning (perception process) followed by a certain conditioned response (learning process experienced due to culture or brand’s marketing strategy), appears relevant to unveil the effectiveness of luxury brands across European consumers. Moreover this understanding should be framed in a cross-cultural context in order to be relevant for the sector (Dubois, Czellar and Laurent, 2005; Shukla, Shkula and Sharma, 2009). Purpose – The aim of this study is to measure the effectiveness of luxury brands strategies, through a cross-cultural comparison. By doing so, the authors attempt to develop a framework that intends to measure the perception process alongside purchase intentions, mapping it with the marketing strategies that have been proposed by brands at different segments. Design/methodology/approach – The methodological approach followed in this paper was to systematically review the academic literature on luxury brands and identify the different concepts of luxury as well as provide an overview of the segment from a European perspective. Through the analysis of the brand strategies used by different typologies of luxury brands (inaccessible, intermediate and accessible), the researchers intended to clarify the learning process and meaning transfer that takes place in the studied markets: UK, Spain, Germany and Italy. Motivations for buying luxury were also measured from a transnational perspective to fully understand matchability in the perception process and purchase intentions. This research has used existing theories based on the areas mentioned above to create hypotheses that were statistically tested using SPSS, evaluating if hypotheses raised can be supported or not. By deductive reasoning, established theories were used to develop and examine hypotheses in contemplation of the explanation of laws (Bryman and Bell, 2011), using a deductive research approach. Through quota sampling the results can be generalized to a larger population. Originality/value – Several authors have pointed out the need for further analysis on luxury value perception (Shukla and Purani, 2012; Tynan, McKechnie and Chuon, 2010; Christodouilides, Michaelidou, N. and Li, 2009; Vigneron and Johnson, 2004; Wiedmann, Hennings and Siebels, 2009) The knowledge on consumers’ perception of luxury should be enlarged and better methodologically oriented, making a transnational research project like this of greater importance. With this in mind, the findings provide valuable strategic insights for luxury brands to use across the different EU markets. Findings –We are running the research so to have the results and provide the expected contribution with this paper.
Chitosan Based Nanocarriers for Indomethacin Ocular Delivery
Badawi, Alia A.,El-Laithy, Hanan M.,Qidra, Riad K. El,Mofty, Hala El,Dally, Mohamed El 대한약학회 2008 Archives of Pharmacal Research Vol.31 No.8
Two different chitosan (CS) nanocarriers namely nanoparticles and nanoemulsion were developed to prolong Indomethacin (IM) precorneal residence time and to improve its ocular bioavailability the main limitations in its management of post-operative inflammation and intraocular irritation after cataract extraction. CS-nanoparticles were developed by modified ionic gelation of CS with tripolyphosphate while nanoemulsion was prepared by spontaneous emulsification technique. Transmission electron microscopy revealed regular well-identified spherical shape. The nanoparticles had a mean size of 280 nm, a zeta potential of + 17 mV and high loading efficiency of 84.8 % while the mean size of nanoemulsion was affected by the nature of the surfactant used and varies between 220-690 nm. In vitro release studies, performed under sink conditions, revealed small initial burst release during the first hour followed by slow gradual drug release of 76 and 86% from nanoparticles and nanoemulsion respectively during a 24 h peroid. In vivo studies and histopathological examination revealed that eyes of rabbits treated with nanoemulsion showed clearer healing of corneal chemical ulcer with moderate effective inhibition of polymorph nuclear leuckocytic infiltration (PMNLs) compared with nanoparticles preparation. Moreover, following topical instillation of CS-nanoemulsion to rabbits, it was possible to achieve therapeutic concentration of IM in the cornea through out the duration of the study and fairly high IM level in inner ocular structure, aqueous humor. These levels were significantly higher than those obtained following instillation of IM solution. Therefore, CS nanocarriers developed in this study were able to contact intimately with the cornea providing slow gradual IM release with long-term drug level thereby increasing delivery to both external and internal ocular tissues.
