Colorectal cancer target referralcancer detection rate and diagnostic Essay

Colorectal cancer target referralcancer detection rate and diagnostic efficacy of the criteria - Essay Example Etiology of colorectal carcinoma is not clear but a few etiological factors have been implicated. These are as under, 1. Geographic variations: The incidence of large bowel carcinoma shows wide variation throughout the world. It is much more common in North America, Northern Europe, then in South America, Africa, and Asia. Colorectal cancer is generally thought to be a disease of affluent societies because its incidence is directly correlated with the socioeconomic status of the countries. 2. Dietary factors: Diet plays a significant part in the causation of colorectal cancer. A low intake of vegetable fiber-diet leading to low stool bulk is associated with higher risk of colorectal carcinoma. Consumption of large amounts of fatty foods by populations results in excessive cholesterol and their metabolites which may be carcinogenic. Excessive consumption of refined carbohydrates that remain in contact with colonic mucosa for prolonged duration changes the bacterial flora of the bowel, thus resulting in production of carcinogenic substances. 3. Adeno-carcinoma sequence: There is strong evidence to suggest that colonic adenoma-carcinoma arises from pre-existing adenomas referred to as adeno-carcinoma sequence. Incidence of adenomas in population is directly proportional to the prevalence of colorectal cancer. 4. ... cular genetics have revealed that there are sequential multi-step mutations in evolution of colorectal cancer from adenomas by mechanisms such as -catenin mechanism and microsatellite instability mechanism. Distribution of the primary colorectal cancer reveals that about 60% of the cases occur in the rectum, followed in descending order, by sigmoid and descending colon (25%), caecum and ileocaecal valve (10%), ascending colon, hepatic and splenic flexures (5%); and quite uncommonly in the tranverse colon. Clinical symptoms in colorectal cancer appear after considerable time. These include occult bleeding, changes in bowel habits, loss of weight ( cachexia), loss of appetitie (anorexia), anemia, weakness, malaise. The most common complications are obstruction and hemorrhage; less often perforation and secondary infection may occur. The prognosis of colorectal cancer depends upon few variables such as extent of bowel movement, presence or absence of metastases, histological grade of tumor and location of the tumor. The most important prognostic factor in CRC is however, the stage of the disease at the time of diagnosis. Three staging systems are in use. They include Duke's ABC staging, Astler - Coller Staging which is a further modification of Duke's Staging and TNM staging described by American Joint Committee (Mohan 601). The methods used in the diagnosis of CRC are as follows: Fecal Occult Blood Testing (FOBT) FOBT is one of the most effective methods for colorectal cancer screening. Reports reveala reduction in colorectal cancer mortality of 12%-33% in a long-term follow up available in four randomized controlled trials and three non-randomized trials of 330,000 and 200,000 individuals respectively. FOBT isvery acceptable as it is non-invasive,programme.

Criminological Theory Essay Example | Topics and Well Written Essays - 1000 words - 1

Criminological Theory - Essay Example The biological perspectives on criminality holds that criminal behavior is caused by physiological factors that are rooted in an individual , the Sociological Development theory provides an integrated approach on the cause of crime in society as an interaction between an individuals and the societies social structures and the Psychological perspective on crime views deviancy and deviant behavior as the product of dysfunctional personalities in an individual. I have utilized the strain theory by Robert Merton as an example of sociological perspective on crime, the Somatotype theory by William Sheldon for the case of biological perspective and the Psychoanalytic theory by Sigmund Freud as an example to Psychological perspective on crime. All this theories will seek to exemplify what cause crime and deviancy in society. This paper will look into various theory of crime in the society that have been put forward to explain causes of crime and deviant behavior and provide an example for each category presented .The theories that seek to explain crime and causes of criminal behavior in society are categorized in biological, sociological or psychological theories of crime. Sociological theories of crime are categorized into four groups namely, the social process theory, the rational theory, the social conflict theory and the social structure theory. The four theories are further categorized as social disorganization theory and the strain theory. The social disorganization theories focus on conditions prevailing in urban centers that influence crime. This theory presupposes that high unemployment, low income levels, large number of single parent households and high college drop outs contributes to crime. The strain theories on the other hand stresses that crime is caused by the existence of conflict between the goals and the legal means that

Shares of companies in an industry are illustrated through pie chart as well as the contribution of sales among geographic locations. Misleading graphs becomes a problem in portraying the real situation. This is as worse as distorting the data set as these are both done in order to exaggerate and convey wrong information to the reader. The graph on the equity market posted on Yahoo finance (http://finance.yahoo.com/marketupdate/overviewu) is an example of a misleading graph. It should be noted that the Dow and Nasdaq markets are shown in two line graphs which uses different intervals. Also, the graphs are misleading because the horizontal axes did not start at zero making the movements in composite price indices appear very large even if this is not the case. This problem can be remedied by displaying the performances of Dow and Nasdaq on one graph. Also, the horizontal axis should start at zero in order to give investors an appropriate view on the changes in composite price indices. The use of focus group can be very helpful in gathering qualitative data especial

Case Scenario Assignment Example | Topics and Well Written Essays - 500 words - 1

Case Scenario - Assignment Example er or siblings but only his mother and the criminal gangs, is sufficient evidence to say that his social environment compromised his rational thinking to opt joining the criminal gangs hence making this case scenario being in tandem and well explained by the Social Disorganization Theory’. Virginia’s case can be well explained by the theories of Biology, genetics & Evolution, which articulate that the behavior of individuals can be genetical, biologically or evolutionary influenced to make individuals commit crime. Given that either Virginia’s mother or her twin sister have been accused or convicted of a crime, it implies that Virginia’s crime behavior of shoplifting is genetically inherited, hence influencing the choices she makes. Therefore, I can authoritatively say that Virginia was born criminal since this can be identified through her identification or stigmata characteristics. Further, we can say that the processes of natural selection, which result in tendencies of criminal genetics that are passed from generation to generation were inherited by Virginia from her mother, hence giving a good explanation of her twin sister and her criminal behavior. Police have no legal right to storm into your home, house or apartment and start ransacking it without probable cause or warrant unless it an emergency. The criminal defense law 407-894-0055 allows you not to allow police enter into your house without a warrant. However, there are some instances when police do not need a warrant to search your house e.g. in case of plain view or when they want to stop a crime in progress. Therefore, given that the police officers are trained narcotic and drug officers, it is probable that the plant they have recognized would indeed be marijuana. Thus, since they have sufficiently determined beyond reasonable doubt that Lucy is a trafficker, they can, therefore, storm at Lucy’s apartment and search for the incriminating evidence without a warrant. Under the Federal

This papers topic is on Sight and Blindness in the play Oedipus Rex Essay

This papers topic is on Sight and Blindness in the play Oedipus Rex - Essay Example In light of this, it can be said that being sighted or blind does not necessarily correspond with the ability to control ones fate. It may be assumed that having the ability to see makes it easier to control fate, however, in Oedipus Rex, it is clearly evident that between physical and intellectual blindness, it is the latter which seems to allow for a more truthful vision of one’s destiny. Oedipus, the protagonist, is arrogant and intellectually blind. It is this arrogance and blindness which actually cause him to eventually fulfill the fate he so desperately tries to escape from. He begins his life with a prophecy from the gods; that one day he will kill his father and marry his mother. In a desperate attempt to avoid this terrible fate, his parents send him into the mountains to die. However, a shepherd saves Oedipus and the child is adopted by Polybus and Merope, the King and Queen of Corinth. While Oedipus was completely unaware of the prophecy during this time, he was safe from fulfilling his terrible destiny. Ironically, it is only when he begins to see the truth that he begins to approach his fate. As he becomes aware of the prophecy, he flees from home for safety in the hopes of avoiding his destiny. However, in doing so, he achieves the opposite; while fleeing Corinth, he meets his real father, King Laius, and kills him. He then makes his way to Thebes where he marries his real mother, Jocasta, and also brings a plague into the city. These events are hugely ironic, because if Oedipus had never become aware of the truth, he could have stayed blissfully ignorant, and safe from fulfilling his destiny. Alternatively, if Oedipus had been aware of the full truth from the beginning he could have potentially avoided his fate. His arrogance is further displayed when he declares that he will find the Kings killer so he can save the town from the plague, unaware that he himself is the killer. We can see that throughout the

OnDemand Group (ODG) Strategic report Assignment

OnDemand Group (ODG) Strategic report - Assignment Example OnDemand Group (ODG) is a medium size British firm, as derived from its employees – about 140, as the relevant criterion is set in the definition of medium enterprises established by the European Union authorities (Europa 2011); the firm has managed to develop a wide network of activities globally, by continuously expanding the range of its activities and by developing important agreements with competitors in foreign markets. Currently, ODG is a member of SeaChange International, a US Corporation, a fact that has enhanced the internationalisation efforts of the organization. In UK, the media and entertainment industry, in which ODG operates is highly developed; in the future, the ability of the firm to face the market pressures, both in the internal and the external market, will be related with the success of the internationalisation process, an initiative developed by the firm’s managers in order to secure the competitiveness of the organization.... This view is based on the foreign direct investment theories which emphasize on the high costs usually related to the internationalisation attempts of modern organizations; it is noted that these costs can be higher from the expected benefits; for this reason, it is suggested that monopolistic advantages are available to firms entering the global market, in order for the deficits caused from high costs – and entry barriers – to be controlled (Krist 2009, p.26). On the other hand, Prashantham (2008) explains the internationalization of firms by referring to their network relations; it is made clear that firms which have an expanded ‘network of customers, suppliers or support agencies worldwide’ (Prashantham 2008, p.34) are most likely to decide entering the global market, based on this network’s support. Certain firms are likely to choose internationalization in order to enter neighbouring countries; these countries, usually, have similar cultural cha racteristics with the country of origin, a fact that facilitates the internationalization process. This mode of internationalization is quite common in Scandinavian firms and it is known as ‘sequential development internationalization model’ (Svetlicic et al. 2003, p.11). At this point, reference should be made to the view of Jones (2009) who noted that the internationalization of a firm should be decided at an early phase of organizational life because in this way the expected benefits can be increased (Jones 2009, p.41). The review of the internationalization efforts of OnDemand Group leads to the assumption that the particular process, which has been in progress almost since the establishment of the organization, has
