Keywords: COPD, cognitive status, dementia, aging Abstract Purpose: Chronic Obstructive Pulmonary Disease (COPD) has been associated with dementia and cognitive impairment. We attempted to assess the relationship between COPD and cognitive impairment in a nationwide database, the National Health and Nutrition Examination Survey (NHANES III). Methods: Data was analyzed from the NHANES III database, a nationally representative cross sectional observational study among older adults. The diagnosis of COPD was based on calculation of FEV1/FVC ratio, with a cutoff of 0.7. The odds of having poor cognitive status was assessed using logistic regression models between COPD and three cognitive tests (immediate recall, delayed recall, and serial subtraction tests), adjusted for demographic variables and medical comorbidities. Results: We identified 17,181,182 individuals with a diagnosis of COPD. The mean age of was 71.5  ± 0.19 years. In the crude model, there was a strong relationship between those with COPD and poor cognitive test scores. This relationship was strengthened in the multivariate model adjusted for demographic variables and vascular comorbidities, such that those with COPD had a higher odds of having impaired immediate recall (OR 2.56, 95% CI 1.44- 4.53), delayed recall (OR 3.10, 95% CI 1.73- 5.52), and serial subtraction tests scores (OR 2.74, 95% CI 1.17- 6.40). Conclusions: Individuals with COPD have a higher odds of having cognitive impairment in this large nationally representative database. Introduction Approximately 35.6 million currently suffer from dementia worldwide, and this number is expected to double by 2030 and triple by 2050 [1]. In the last few years we have become more cognizant of the importance of identifying cognitive decline at the earlier stages when it is more amenable to treatment. We have also become more knowledgeable about possible comorbidities that may propagate the process of cognitive decline and ultimate dementia. Causes of cognitive decline, and possible progression to dementia, are believed to be multifactorial. Chronic Obstructive Pulmonary Disease (COPD) is a progressive disease that affects more than 13.5 million people in the United States and has been associated with cognitive decline [2]. To date, there are no definitive treatments for dementia; therefore, much emphasis had been placed on the prevention of dementia, and identification of modifiable risk factors early in the disease process. Multiple studies have reported the association between COPD and either global cognitive deficits with the most severe deficiencies in specific cognitive domains such as perception, motor function or memory [3]. Despite the current body of evidence, the majority of studies are based on a single region, and there are a few studies that used a nationally representative data (Health and Retirement Study). Given that society is facing an increase in the rate of chronic diseases of aging [4], and the lack of large scale investigation on the relationship between COPD and diminished cognitive status, we analyzed this nationwide database, the National Health and Nutrition Examination Survey (NHANES III), to better elucidate this relationship. Materials and Methods NHANES III is a cross sectional health survey conducted by the National Center for Health Statistics (NCHS), performed from 1988 to 1994 in persons aged two months and older in the United States. NHANES has a multistage, probability sampling design used to select participants representative of the civilian, non-institutionalized US population. Our study population consisted of 39,488,973 adults 60 to 89 years. Of these, participants were included if they had measurements for spirometry and the cognitive tests. Based on The Global Initiative for Chronic Obstructive Pulmonary Disease (GOLD) standards, cases of COPD were defined based on the patient’s ratio of forced expiratory volume (FEV1) to the forced vital capacity (FVC). Patients with a ratio of less than 0.7 were classified with COPD. Our control group, patients without COPD, was classified by a ratio greater than 0.7. For the older population, NHANES-III measures cognitive status with three cognitive tests: an immediate a nd delayed logical verbal memory test from the East Boston Memory Test, a three word registration/memory task (â€Å"apple,† â€Å"table† and â€Å"penny†) and five serial subtractions by intervals of three. A point was awarded for every correct answer from the three word memory task and the logical verbal memory test. For immediate memory, using a summary score of logical memory (0-6 points) plus three word task (0-3 points), we considered less than 5 out of 9 points to be impaired (low), such that individuals with 0-4 were score ‘low’, and those scoring 5-9 were scored ‘high’. For delayed memory, a summary score of less than 4 out of 9 points was considered impaired (low). Both summary scores are consistent with previous NHANES-III reports. For the test of serial subtractions, any miscalculation during the five trials was considered impaired, and only a perfect score was considered ‘high’. The reported race and ethnicity includes non-Hispanic Whites, non-Hispanic Blacks, Mexican-Americans and ‘other’. Smoking was defined by a â€Å"yes† response to the following two questions: â€Å"Have you smoked at least 100 cigarettes during your entire life† and â€Å"Do you smoke cigarettes now†. These questions can be found on the NHANES III household adult questionnaire. Education was stratified in three categories: 12 (some college and beyond). We performed an X2 and t-test analysis to compare demographic characteristics between patients with COPD and patients without COPD. To assess the association between COPD and a low cognitive test score (with high score as reference) crude and adjusted logistic regression analysis were performed. Adjusted potential confounders were age, race-ethnicity, sex, BMI, education status and smoking. Appropriate NHANES-III weighted sampling was applied during this analysis. All data analyses were conducted using SAS (v 9.3; SAS Institute Inc., Cary, NC). Results Table 1 presents the demographics of the population. There were 17,181,182 individuals with COPD; 50.1% were females, 49.9% males and 85.9% were non-Hispanic White. The mean age for patients with COPD was 71.5 ±0.19. In both groups, patients had less than a high school education, were non-smokers and had both hospital and medical coverage. Majority of individuals with COPD scored low on each cognitive test as compared to those without COPD (Table 1). Coronary artery disease was the most prevalent comorbidity in patients with COPD (31.9%) and in patients without COPD (30.4%). In the unadjusted model, participants with COPD had increased odds of impaired scores on each of the three cognitive tests: the immediate recall (OR 2.18, 95% CI 1.81- 2.62), delayed recall (OR 2.25, 95% CI 1.87- 2.70) and serial subtraction test (OR 1.44, 95% CI 1.10-1.90). We then examined the association between COPD and the cognitive tests, initially adjusted by age and race, which diminished the relationship slightly for all three tests, but the relationship was rendered insignificant for the serial subtraction test (OR 1.29, 95% CI 0.95-1.69) (Table 2). Then, we adjusted for age, sex, height, body mass index and education, which did not change the relationship significantly. In the third model, further adjustment for race, poverty income ratio, and medical coverage did not appreciably change the relationship. In the last model, we additionally adjusted for vascular risk factors such as smoking, stroke, hypertension, CHF, diabetes and coronary artery disease. This increased the odds for poor scores for all three tests; immediate recall (OR 2.56, 95% CI 1.44- 4.53), delayed recall test (OR 3.10, 95% CI 1.73- 5.52), and serial subtraction (OR 2.74, 95% CI 1.17- 6.40). Discussion We were able to identify a strong association between COPD and diminished cognitive status across three common cognitive tests. Individuals with COPD had significantly greater odds of impaired verbal memory, and this relationship remained robust after adjusting for potential sociodemographic and vascular risk factors. The relationship between COPD and the serial subtraction test scores was rendered significant after it was adjusted for vascular risk factors. Despite evidence in the extant literature showing an association between race with cognitive status [10], race was not a factor in the relationship between COPD and cognitive status. Our results are consistent with a growing body of evidence that has revealed a strong association between COPD and poor cognitive function. In one of the largest epidemiological studies, The Health and Retirement Study (n=4,150), patients with severe and non-severe COPD had significantly lower cognitive test scores compared to healthy controls. In adjusted models, only patients with severe COPD had the lower scores on the cognitive tests [5]. Furthermore, a dose-response relationship between COPD severity and cognitive dysfunction was previously established, with more severe COPD cases performing worse on the cognitive tests [6]. Notably, a 2013 study demonstrated significantly reduced memory tests scores on the Mini Mental State Exam (MMSE) among patients with COPD but without hypoxemia [7]. Further evidentiary support for global cognitive impairment in patients with COPD was also shown in a study that observed significant differences in executive functioning, working memory, episod ic memory, processing speed, and visuospatial ability [8]. Recently, several COPD studies have combined cognitive testing with neuroimaging, which have revealed significant white matter pathology in this population, with varying degrees of cognitive impairment [8,9,10,11]. The mechanism by which COPD causes cognitive decline is not very clear. COPD results in hypoxemia and hypercapnia, which has been implicated in diminished cognitive status [3,5]. Recent imaging studies have pointed to possible microvascular damage [3], and other studies have implicated chronic inflammatory process causing cognitive decline [12]. Yet others believe that the hypoxic process may cause direct neuronal damage, glial activation and the generation of free radicals which could affect cognitive functioning [13]. Given the prevalence of both COPD and cognitive decline in the elderly population and a probable causal relationship, it is important to further investigate the mechanism underlying the relationship. Limitations As all studies, this one has many limitations that need to be visited. One of the limitations unique to our study was that majority of the individuals in our elderly NHANES population had less than high school education. Given that educations has repeatedly been found to be strongly correlated with resilient cognitive function as well as less susceptible to neurodegeneration, our results could have been confounded by the lower mean education level in our population[14-18]. Another limitation lies with the cognitive testing used by NHANES. Only three cognitive tests were utilized, which does not provide a comprehensive assessment of cognitive function. In addition, the cognitive tests used most likely overlap in the cognitive function they measure, not allowing for specificity. However, the cognitive variables have been validated as a good tool for testing memory [19]. Furthermore, the cross-sectional nature of this paper does not allow us to make a causal link. In addition, the restr icted scope of lifelong socioeconomic status is a limitation, which is strongly associated with both cognitive impairment and COPD. However, it has been demonstrated that individuals with poor socioeconomic status may have a higher risk of developing COPD and lower cognitive reserve [20,21]. The strengths of this study are its large, diverse representative sample, that provided extensive medical history and allowed for control of confounding variables, as well as the objective measure of cognitive impairment and COPD. Also, the spirometry data from NHANES III allowed for more accurate diagnosis of COPD. Conclusion We were able to demonstrate a strong relationship between COPD and diminished cognitive status. We were not able to demonstrate any effect of gender, race, as well as sociodemographic or vascular risk factors on this relationship between COPD and cognitive status. The independent relationship between COPD and cognitive status may provide us an important clue into the pathophysiology of dementia, which needs to be further explored.

The Duration Of Coaching Csa Trinity Education Essay

Knowledge is deemed an indispensable portion of training within any clean environment. Furthermore, within any clean environment all managers require some sort of training cognition whether novitiate or expert in which constructed throughout life or coaching experiences. Coaching cognition is critical whether planning, coach/athlete relationship, analysing, and observation etc†¦ In which is important towards participants larning. Therefore, the intent of this paper is to find whether any cognition has been extended and how farther cognition can be constructed to heighten personal coaching towards accomplishing long clip personal end of expertness coaching. This will be completed via 20 completed hours with the CSA Trinity ( CSA ) and training Sessionss which were delivered within the 12 hebdomads at Oxford Brookes University to detect if any patterned advance from a novitiate to expert knowledge base manager. Phases of development Throughout the continuance of training CSA three Football Club training observations were deployed towards myself via feedback from participants and parents to find what training degree public presentation stood. Mention to appendix 5, manager public presentation feedback sheets. As Bloom ( 1985 ) provinces, three stages of the faculty include induction, development and flawlessness in which designed to better immature jocks within a suited environment and hence enhances the development of expertness. However, a somewhat different position from Dreyfus and Dreyfus ( 1986 ) whereby expertise accomplishment involves five phases of completion novitiate, advanced novice, competent, proficient and expert within anyone ‘s field of expertness. Conversely, farther surveies demonstrate several transmutations of athletics context as Cote ( 1999 ) adopted four phases and designed a faculty to raising and develop participants, but besides could drop out at different phases in required duri ng the sampling, specialising, investing and diversion stages. Another theoretical account as Bush and Roberts ( 2011 ) Schempp et Al ( 2006 ) suggest managers ‘ demands of going an adept practician involve extended cognition base. However, in order to make drawn-out cognition base managers require commence through four phases of development, novitiate, competent, proficient and expert. Though each theoretical account demands are important in order for development to make a 1 ‘s end â€Å" expertness † significantly for different types of work industries and degrees of abilities. However, Hargreaves and bate ( 2009 ) province ; experience and cognition are good as developing and training the participants within the session to obtain improved accomplishments and cognition of the game, instead than running a session via accretion drills. Furthermore, Bush and Roberts ( 2011 ) Schempp et Al ( 2006 ) suggest, novice accent lay on participant ‘s behaviors than slightly developing the participant and hence, no future battle of cognition to better acquisition. However, Schempp et Al ( 2006 ) continues, within the competent stage, cognition is consumed to diminish the sum of errors that occur, but every bit concerned with regulations, such as no speaking policy when manager is speaking. Therefore, competent coaching within the first five or six hebdomads at University and ( CSA ) as somewhat confounding due to letters of information received within talks. Consequently, deficiency of experience and cognition prevailed as proficient cognition, contemplations ; planning, coach/athlete relationship and coaching manners etcaˆÂ ¦ were slightly a learning stage and hence running alternatively of training a session in which no acquisition or developments took topographic point when presenting Sessionss. Mention to appendix 4, brooding journal and one to six hebdomads of session evaluations/reflections for under 8 ‘s and 11 ‘s. For that ground, building cognition was the following phase in order to accomplish a degree of proficiency as Perlus ( 2008 ) feels that, training cognition comes from personal experiences, i.e. playing the athletics, expertise degree and context etcaˆÂ ¦ and hence playing ability is indispensable in which refines training cognition. However, these properties would hold a certain grade of effectivity, although non indispensable to go an adept manager. For illustration, Linford Christie ‘s ex-coach Ron Roddan highest accomplishment was running for his county Middlesex and Jose Mourinho current Real Madrid director both encountered short low profile, playing callings. As Carter ( 2006 ) provinces, Jose Mourinho playing calling was really brief, nevertheless, during his brief enchantment as a participant whilst analyzing football methodological analysis within Lisbon ‘s Sports University. Therefore, increased his cognition base in which Mourinho encountered all phases t o expertise which lead him to assorted assistant/manager occupations at high-profile nines. However, deriving experience from old playing calling is non indispensable to derive expertness cognition. Whether professional jock or playing recreational athleticss expertness cognition can be gained through sheer finding and motive and create solid foundation within training. Therefore, indispensable for different facets to derive cognition, i.e. experiences, books, diaries, analyzing public presentation, playing experience and detecting other coaches- penetration into tactics and technique and feedback are important constituents to make coveted end of expertness. Mention to appendix 1,2,3,4 and 5 of portfolio. However, deriving expert cognition requires hours and old ages of deliberate pattern harmonizing to Ericsson and Charness ( 1994 ) , Nelson et Al ( 2006 ) , Ericsson et Al ( 1993 ) , Schempp et Al ( 2006 ) , cote ( 2006 ) and Gilbert et Al ( 2006 ) which are from different Fieldss and slightly indecisive within the continuance and experience to necessitate expertness cognition base. Nevertheless, all theories fluctuate and suggest five, 10 and 13 old ages, 3,000 to10,000 hours to make full potency. However, Schempp et Al ( 2006 ) provinces, adept cognition are neither familial nor typical features, but fineness within training which instruction and experience in which can be expanded over hours or old ages of deliberate pattern dependant on the single motive of success. Though, depending on what type of coach/person, sheer finding, personality, visions, passion, motive and ends etcaˆÂ ¦ you possess cognition. Hence, experience could be administered quicker to stand out from novi tiate to expert to accomplish the end they require as Schempp et Al ( 2006 ) points justly out. Finally, if required plenty cognition and content with the degree of coaching/knowledge, managers may choose to halt if gained a degree of efficiency. Another method which coaches concept cognition is formal, non-formal and informal manager larning whereby ongoing and womb-to-tomb development to build farther cognition in different organisations. As Nelson et Al ( 2006 ) , Bush and Roberts ( 2011 ) , Smilde ( 2009 ) and Edwards et Al ( 2006 ) study that, formal acquisition is institutionalized and organised instruction system with inactive or additive learning aims and chief focal point is the merchandise and non the procedure for illustration, course of study administrations i.e. BTEC, national government organic structure ( NGB ) classs and degrees-foundation grades etc.. â€Å" enfranchisement constructed † . For case Ehlers ( 1998 ) found that, disadvantages occur within formal larning ‘learners remember merely 20 % of the information presented during a formal lesson ‘ . Consequently, formal acquisition has no consideration for the individual/learner and low impact on cognition and hence, decreases the trouble of the demands of the manager. For illustration, managers, possibly hesitant when using cognition to pattern, when and how to train. Although, Nelson et Al ( 2006 ) , Bush and Roberts ( 2011 ) , Smilde ( 2009 ) and Edwards et Al ( 2006 ) continues, non-formal acquisition takes topographic point outside formal acquisition within workshops, groups, administrations and best pattern etcaˆÂ ¦ acquisition does non happen, because, on the other manus good for basic apprehension. However, inordinately hard to mensurate if learning/knowledge has taking topographic point as no base on balls or fail occurs and hence, does non supply a model which is critical for building training cognition. Though, Informal larning consists of building cognition, developing accomplishments and behaviors which benefit training pattern via the usage of diaries, books, pictures and autonomy etcaˆÂ ¦ . Therefore, research and acquisition within the environment over ongoing life long procedure is good for expertness cognition. For illustration, detecting to dispute something, reflecting in ( within session ) and on ( after session ) pra ctical, proficient and critical jobs can make a deeper acquisition or development of training cognition. Mention to appendix 6, readings-development of adept training page 2 and 6. However, persons are slightly different and learn at different velocities, ways. Therefore, to make a sound cognition base, formal and non-formal acquisition would supply non merely enfranchisement, but a foundation for patterns, drills and the rudimentss apprehension of the coaching environment. However, informal, the most good, but using cognition from informal with the usage of the non-formal and informal would turn out slightly good for some persons within the coaching environment. Hence, persons learn otherwise i.e. in their ain in manner which they feel conformable, see different chances to detect the result themselves etcaˆÂ ¦ to accomplish a certain end. Areas of cognition The sentiment of Cassidy et Al ( 2004 ) and Robyn et Al ( 2008 ) is that, the work from researcher Shulman ( 1986 ) in respects to content cognition required three subdivisions, capable affair content cognition ( SMCK ) refers to the manager and cognition to present a session i.e. nucleus accomplishments accomplished by the participants whilst the regulations are coached etcaˆÂ ¦ pedagogical content cognition ( PCK ) is the ability to learn or pass on whilst engaged with the ( SMCK ) participants. Finally, course of study content cognition ( CCK ) ‘tools of the trade ‘ as mentioned by Robyn et Al ( 2008 ) , intending explicating and analyzing the capable affair towards pupil acquisition. However, Metzler ( 2000 ) suggests, Shulman ‘s work is a great get downing point in respects to content cognition. However, Metzler ( 2000 ) continues, farther dislocation of the current constituents into a farther three classs declarative, procedural and conditional cognition would be good as it would go confidant within the designated athletics. Therefore, Metzler ( 2000 ) and Bush and Roberts ( 2011 ) portion the same position in that declaratory cognition ( DK ) in which managers explains and show verbally or within a written format, i.e. the cognition about and facts and things. Metzler ( 2000 ) and Bush and Roberts ( 2011 ) continue, procedural cognition ( PK ) , intending â€Å" knowledge how too/ how to accomplish it † i.e. how to execute a undertaking or process and conditional cognition refers to when and why to make something and what happens if. Refer to appendix 6, readings-development of adept training pages 5-6. However, both Metzler ( 2000 ) and Shulman ( 1986 ) in respects to all classs are slightly good when using both methods together within the coaching environment whereby managers can better participants ‘ public presentations and hence, larning takes topographic point as the cognition to acquire something done had occurred â€Å" adept Coaches † . Mention to appendix 2 Sessionss plans 9 and 10 of both under 8 ‘ & As ; 11 ‘s. The latter phases of the 20 hours training and lectures going more confident as expanded cognition and experience was clearly apparent as some larning took topographic point. Therefore, proficient cognition, reflections/evaluating, planning, coach/athlete relationship and coaching manners etcaˆÂ ¦were developing together non merely certain facets of coaching. However, due to huge accrued cognition and experience proficient cognition base was more distinguished, but still needs betterment. Mention to appendix 4, brooding journal and seven to ten hebdomads of session evaluations/reflections for under 8 ‘s and 11 ‘s. Though, concentrating more on the participants ‘ performance/development, participant battle instead than running a session as before. However, expert knowledge more formidable and hence, more cognition and experience required to make lifetime end â€Å" adept cognition base manager † . As Schempp et Al ( 2006 ) Wiman et Al ( 2010 ) conclude to derive expertness cognition involves changeless planning for coveted results of Sessionss, deriving cognition all the clip via diaries, books, workshops, programmes which involve enfranchisement etc.aˆÂ ¦ Furthermore, larning and detecting from other adept managers, experience etc†¦ Refer to appendix 5, peer observations-strengths/weaknesses Decision Given this grounds, it can be seen that managers get cognition they need to be effectual and adept manager via different methods through a figure of formal, non-formal and informal acquisition environments. However, larning is diverse and dynamic procedure in which is really typical and hence, different to being taught something within instruction. Therefore, indispensable to derive cognition through all types of experiences from playing recreational to professional athleticss, reading diaries or books, written work, workshops programmes which involve enfranchisement etcaˆÂ ¦ Furthermore, deriving expert cognition requires hours and old ages of deliberate pattern all dependant on what type of attitude the coach/person requires as sheer finding, passion, and motive to make the coveted ends could stand out towards the journey of dream end â€Å" adept manager † .

GM Food Essay

You are required to write an article titled GM Food on the basis of websites and sofewares. In the article, you are expected to present the points as follows: the definition of GM food, the possible prospects and problems, your attitude towards GM food. The article should be no less than 500 words. Genetically modified (GM) foods are foods derived from genetically modified organisms. Genetically modified organisms have had specific changes introduced into their DNA by genetic engineering, using a process of either Cisgenesis or Transgenesis. GM foods were first put on the market in the early 1990s. Typically, genetically modified foods are transgenic plant products: soybean, corn, canola, and cotton seed oil. Last year, the Ministry of Agriculture awarded the safety cerfiticate to two kinds of transgenic rice, and this triggered a large-scale discussion. Many people oppose it and refuse to eat GM foods. They objected to GM foods on several grounds such as: †¢ GMF’s have not been a success, there is no test in human being. The GM foods maybe change human gene in future. †¢ Genetically modified crops will affect other plants around them and change other species, then more and more species will vary or disappear. †¢ GM foods have the advantage in both price and output, so traditional farmers will lose the market. Then few companies who have transgene proprietary technology will control food market. On the contrary, many proponents of GM foods have other opinions: †¢ People eat GM foods, then the foods are analysed and assimilated like normal foods, there is no theory to support that GM foods will change human being’s gene. †¢ There is a food supply issue in the developing world, in order to meeting the demand for food and confronting the climate change we need to increase use of GM crops. †¢ The GM crops use less pesticide, It is more safty than normal crops. Actually, more and more GM foods appear in our lives. When you have dinner in the restaurant, maybe you eat the GM oil, GM corn and GM rice, but you just don’t know. Genetically modified food is science brings us the product, now of cultivated land area of less, genetically modified food will play more and more important role, if the use of transgenic technology can solve the world food shortage problem, it is not quite good? Genetically modified food in the world now is a kind of new things, new things, people need time to promote its accept also need some time, we cannot put new things in the cradle, a stick to it from the beginning, that cannot be eaten of genetically modified food. You think we don’t of hybrid rice is a genetically modified food? But we can open it from? And if they can pass the soybeans genetically modified technique using atmospheric nitrogen inside his produces fertilizers to other crops gene transfer in the mankind, it is. Everything is both sides, especially technology, science and technology is a double-edged sword? Genetically modified food has its disadvantages, like some worry, because it will not change, will destroy genetic evolution, etc. Genetically modified food and nutrition inside it isn’t like that, the propaganda of people worry is understandable, after accepting a new things take time. But we also should see the benefits of them, I think as time slowly past, genetically modified foods will be accepted by people.

Importance of Ben Loman in Arthur Millers Death of a...

The Importance of Ben Loman in in Arthur Millers Death of a Salesman Ben Loman is an important character in Death of a Salesman but he is quite unusual. The audience encounters Uncle Ben during Willy Lomans hallucinations of the past and as a result, it is tempting to disregard his character as just another creation of Willys delusional mind. However, Ben is much more than that. His character is representative of Willys unrealistic dreams as well as the realty of his life. When the audience first encounters Ben (Miller 44), he represents the success that Willy is striving for.
