This meta-analysis has helped me view myself and feel like an expert in my field of study, understanding the difficult requirements of success. Also, it has increased my confidence in the course I am currently undertaking. When there are stipulated search strategies and methodically data-base searches there is a very low possibility of having errors, brought about by gaps which contain crucial parts of a piece of work. I also made many mistakes and this sometimes is necessary. Because I made so many mistakes, I had to learn a lot more and spend a lot more time analyzing studies, which gave me a better understanding of diabetes as well, getting a better idea of how medications become used in clinical practice. At times the whole process make
...n Article Nielsen et al (2013) Diagnostic Accuracy hierarchy methods is applied which is review on second level (II) i.e. Randomised Controlled Trial and Meta-Analysis in the Pyramid level. These are also considered as gold standard in hierarchy of research design for evaluating the safety of a treatment. Also therapeutic study method is applied where different patients of age groups are used to treat with two different temperatures. There are two different trial methods used in this study. Here the level of hierarchy is high so that we can trust the result based on the data provided. We can also provide and opportunities to collect useful information about adverse affect such as temperature control over cardiac arrest. In the Meta-Analysis method multiple treatment groups are been treated with each other. There is also observational study performed in the article.
This systematic review conducted by Takeda A, Taylor SJC, Taylor RS, Khan F, Krum H, Underwood M, (2012) sourced twenty-five trials, and the overall number of people of the collective trials included was 5,942. Interventions were classified and assessed using the following headings.-
Alphonse Gabriel Capone was the most notorious bootlegger in American History. He was born on January 17, 1899 and died of a heart attack on January 25, 1947. Capone grew up in Brooklyn and became a member of the Five Points Gang. During a street fight he had received a scar on his face that gave him the nickname “Scarface”. Capone quickly moves up the ranks in the mafia world, often noticed for his toughness, in 1919 he grabbed the attention of mobster John Torrio of Chicago. Capone was promoted to bodyguard of the mob boss James Colosimo. When Capone moved to Chicago, bootlegging was just starting to blow up. These bootleggers pounced on the opportunity to completely control the business of making, importing, and distributing alcohol and all alcohol products. Alcohol wasn't the only flourishing industry for the the mob, they also did trade in
Journal of Continuing Education in Nursing, 44(9), 406. doi:10.3928/00220124-20130617-38. Torpy, J. M. (2011). The 'Standard' Diabetes. Jama, 305(24), 2592 pp.
The six articles that appear in this issue of Journal of Obesity and Bariatrics uphold that value by using visual aids such as tables and statistical figures. For example, author Yishai Levy (2015) argues that bariatric surgery is a potential cure for Type II Diabetes (pg. 1). First, Levy supports this claim by using three tables of data, which she uses to demonstrate the effectiveness of bariatric surgery on aspects of the body like glucose homeostasis, blood tests, and inflammatory markers, (p. #3). She also uses statistical figures such as, “50% improvement in liver enzymes,” and “46% change in excess weight loss” and using such data, she adds more authority to her claim through the power of numbers (p. #3). The use of tables can help the audience better understand the results of the study and allows the author to present the results of her findings in a clear and concise manner. One thing to consider is that replication is important in natural sciences such as Bariatrics, and by providing numbers, the author makes it important to replicate her findings to determine the reliability and validity of her
...audited their search results. Agreement on the findings in the studies was obtained through consensus. Houser (2012), states that studies such as this which review multiple studies “compensate for many threats to internal validity” (p. 268). Duggleby et al. (2012), admits that there were limitations as the metasynthesis of the studies included the authors assumptions which is not actual data. In addition, the report admitted that the search results contained findings based on multiple fatal illnesses and the understanding of hope might be different if it had included people with non-fatal illnesses. Houser (2012) would consider this a threat to the internal validity as there is bias involved with the author’s assumptions and the selection of only people with fatal chronic illnesses. There was no indication of any ethical violations in the meta-synthesis review.
When caring for patients it is fundamentally important to have a good selection of up to date evidence Based Practice clinical articles to support research strategies, this allows professionals to assemble the most resent and accurate information known which enables them to make decisions tailored to the individual’s plan of care. It is essential to have clinical expertise and have the involvement from the individual patient, they must have full engagement and incorporation in order to have the accurate evaluation.
Having a large sample size in a survey does not assure accurate statistics. What really matters is the sample diversity. For example: you wanted to find out how many of your workmates watch football, it would be foolish to only survey the men in your office and assume that the statistic applies for all the company’s employees. In order to get accurate statistics, you would have to expand the survey to include the female employees and the workers in other company offices.

The development of knowledge requires a number of processes in order to establish credible data to ensure the validity and appropriateness of how it can be used in the future. For the healthcare industry, this has provided the ability to create and form new types of interventions in order to give adequate care across a of number of fields within the system. Research then, has been an essential part in providing definitive data, either by disproving previous beliefs or confirming newly found data and methods. Moreover, research in itself contains its own process with a methodological approach. Of the notable methods, quantitative research is often used for its systemic approach (Polit & Beck, 2006). Thus, the use of the scientific method is used, which also utilizes the use of numerical data (Polit & Beck). Here, researches make use of creating surveys, scales, or placing a numerical value on it subjects (Polit & Beck). In the end the resulting data is neutral and statistical. However, like all things its approach is not perfect, yet, it has the ability to yield valuable data.
Overall, the researchers reasonably handle, carried out and contextualize the whole procedure of the operational phases of the study process with clarity and rationality. As I get ready and thoroughly consider for my future research, this study has provided me with a glance of the vital things that I must incorporate in my trialing.
The authors have not needed ethical approval to carry out this study as only published data that were in public domain were used. However, certain ethical considerations have been adhered to. Wager and Wiffen (2011) identified some ethical considerations authors of literature reviews need to adhere to. Whilst their primary focus was on authors writing systematic review for Cochrane journals, the suggestions are applicable to all authors of any form of literature review. The six suggestions are as follows:
There are some key distinctions between Randomized Controlled Trials (RCT) in a psychotherapeutic context and a medical context. There are key differences between the design of an RCT to evaluate a new drug and an RCT to evaluate a new form of couples’ therapy. However, it is important to begin by defining and understanding the importance of RCT in research (O'Brien, 2013).
There are varying standards of science when it comes to evaluating and judging the efficacy and progress of each branch of science. With the Randomized Control Study being the gold standard for medical care and the estimated 16,000 of these studies being published yearly,2 it is of the utmost importance to all practitioners of medicine to be educated in and be able to use EBM. The physician assistant discipline of medicine is no stranger to the utilization of EBM as it has been a growing par...
When I began to look up resources for this paper, I decided to first decide how I would go about finding my sources. A good place to begin to research a particular area of medical or scientific practice would be a textbook dedicated to the related field. Textbooks are generally regarded as excellent sources of information and are usually based on a lot of peer reviewe...
