Ulcerative colitis - Essay Example 2006). This paper will be divided into two main categories, whereby the first category will outline the characteristics and nature of Ulcerative Colitis. There will be a thorough discussion of what the disease is and what it is not in terms of its similarities and differences to Crohn's disease, as well as according to its prognosis. The second category will highlight the skills of a nurse necessary in managing patients affected by this disorder. In such, there will be a clear definition of the management and care that is justified with rationale and scientific explanation. The second category will also address the case study present. It is the intent of this paper to establish a complete understanding of the disease as well as the medical management aspect that is vital to the kind of care provided to patients. More than 500,000 Americans suffer each year from ulcerative colitis, Like Crohn's disease; it can be painful and debilitating and sometimes lead to life-threatening complications. This is according to the Mayo Clinic. Thus the case at hand presents Claire O'Brien, a 32 years old female admitted for possible bowel obstruction and passing of watery stools with bright red blood every 2 to hours. Initial diagnosis purports ulcerative colitis thus prompting the patient for immediate surgery, undergoing colon resection and formation of the colostomy. She is wheeled in to the ward under my care with an Intravenous Line, and has been ordered for a nasogastric tube insertion. Thus a question is raised at this point, what then is Ulcerative Colitis, and how does this disorder affect a person The answer lies in the discussion of the pathophysiology of this disease with emphasis to its etymology, symptoms and prognosis. Ulcerative Colitis is a non-specific inflammatory condition of the colon, a disease that begins often between the ages 20 and 25 years of age but may affect both young and old alike (Cotran, ET al.p776.1999). This tends to have flare-ups that later settles down again for variable amounts of time, yet it is possible to have a single attack. This disease usually begins in the rectum and spreads proximally, affecting primarily the mucosal layer, although it can extend into the lower submucosal layer. The length of proximal extension varies and may involve the rectum alone, thus called ulcerative proctitis, the rectum and sigmoid colon thus called proctosigmoiditis, or the entire colon otherwise known as pancolitis. The inflammatory process tends to be confluent and continuous instead of skipping areas, as it does in Crohn's disease. But unlike Crohn's disease that affects various sites in the gastrointestinal tract, Ulcerative Colitis is confined to the rectum and the colon. Both illnes ses though do have one strong feature in common. They are marked with an abnormal response by the body's immune system. The immune system is composed of various cells and proteins that protect the body from infection. With inflammatory bowel disease the immune system react inappropriately mistaking food, bacteria and other materials in the intestine for a foreign invading substance and thus

Teen Pregnancy Essay example -- Teenage Pregnancy

There is a lot of teen mothers growing up in this world wondering, what if I would have stayed in school? W hat could I have become? Would it have made my life easier if I had thought first? There is many causes for teen pregnancy. They lead to the need for the desire of love by another person. One might have a poor home life and would want something like their peers have. A teen may have a low self-esteem and simply be looking for acceptance. However, many teens that have a wonderful family and are very confidante arnt looking for the few minutes of pleasure. As several teens use the excuse that sex feels better without a condom pregnancy is likely to occur just because of that simple saying. Having a child comes with a lot of responsibility. Teens don’t think of the consequences of their actions. Children take up a lot of time, which also means, no more school. The teen should first understand that all their free time is lost, that she will have to find some way to live for herself and the child, and that any future plans are now not what she was planning. It all comes down to the education of the teen. The more they know about sex and it’s consequences at a young age the less likely they are to go out and be irresponsible about it. Teenagers that learn about different types of protection and how they work is some times one of the best ways for them to think befor they act. Every year one million teenage girls become pregnant in the United States. Teen pregnancy is a major problem in the United States. There are more teenage pregnancies in the United States than all other countries. in this day and age the rate of teenagers who become pregnant has increased. I am not one of them, but having a few fr... ...l regret your choice. The precents of teenagers getting pregnate without being married , I agree on. Teens are usualy left alone rasing their baby by their selfs. that’s why condoms and other helpful things exsicist. If having a relation ship between the opposite sex if the only cure for you problems think twice! Teens like me should be more muter. Besides wondering of into a world that carrys out to a risk in your life. Do some research, think befor you act and is that what you realy want. Just to please the opposite sex by actualy letting them in you, should have to be a second thought. You should amidiatly say no if the opposite sex isn’t married with you in anyway. Being a pregnate teen is alot of responsibility. All in all many teens please their opposite sex by the wrong way. So always researching on what you realy plan on doing is a risk in you own life.

Cultural Imperialism Is Power Essay

â€Å"Cultural imperialism† is what takes place when a large, powerful, economically dominant nation promotes, imposes, or otherwise spreads its own culture to less powerful, economically subservient nations. A. Examples Cultural imperialism is already evident throughout the world: Palestinian Arabs chanting â€Å"Death To America† do so while wearing Nike tennis shoes and t-shirts; Brazilians who curse George W. Bush nonetheless cheer for Madonna and Britney Spears; Turks who protest the ongoing occupation of Iraq may still stroll into a local McDonald’s for lunch; MTV reports 280 million subscribers throughout the world (Galeota, 2004). B. Hows and Whys In 1984, Harvard business professor Theodore Levitt warned that â€Å"the world’s needs and desires have been irrevocably homogenized,† adding that those companies that attempted to accommodate local tastes were â€Å"doomed to failure† (Galeota). II. The Means Today, with global travel and communication easy and quick, American Culture can be disseminated more widely and faster than ever. A. Marketing Images are everything. American corporations have been highly successful at portraying America as â€Å"The Land of the Cool† (Galeota, 2005). This results in an increasing demand for American goods, films and music. B. Communications The Internet has revolutionized communications, and because of forethought and planning, the U. S. has come to dominate the global traffic and marketplace of ideas and information. This has created a tremendous influence over the tastes and desires of people all over the world. III. How It Makes America Strong Darwinism is a fact of life, whether biological, social, or economic; only the strong survive. When the powers of Europe began staking their claims to overseas territories in order to feed their industries and expand their markets, the U. S. had a choice: stay out of the game and continue as a second-rate backwater, or get into the game and reach its full potential. U. S. power and prestige in the world owes a great deal to those visionary leaders who were willing to force open the medieval kingdom of Japan in 1854, to annex the Kingdom of Hawaii and seize Puerto Rico and the Phillipines when the opportunity was there. Today, America owes its incredible economic might to those leaders, who laid the foundations of Empire when Admirial Perry sailed into Tokyo Bay over 150 years ago. Conclusion: For better or worse, American culture is pre-eminent in the world today. Ultimately, this will be to the benefit to the entire world, ultimately making America a safer, more prosperous place.

2. Temporal variability of alkaline earth metals in seawater: implication for variation in geochemical cycling Ocean plays a key role in geochemical cycling of alkaline earth metals that are directly connected to the global C-cycle. Hence secular variation of elemental and concentrations and isotopic compositions of seawater can reflect major changes in the lithosphere and the atmosphere over geologic time. Consequently, elemental and isotopic composition of marine chemical sediments (e.g., carbonates, oxides and evaporates) have been utilized extensively as geologic archives that potentially record secular variation of ocean chemistry. Long oceanic residence time of metals like Ca, Mg, and Sr makes them potential to record long-term†¦show more content†¦Although, the high temperature basalt-seawater interaction in the mid oceanic ridge axis considered to have no isotope effect on the seawater Mg, the potential of fractionating Mg isotopes during seawater circulating through low temperature ridge flanks is still unexplored. Hydrothermal removal of Mg in the MOR flank can vary between 10-80% of the total Mg removal via seawater-basalt interaction and part of that Mg is incorporated into the CaCO3 precipitated to form calcium carbonate veins (CCV). Given the abundance (1-4 vol%) of CCVs in the upper ocean-ic crust and potential to incorporate significant amount of Mg (~10 times more than biogenic calcites) CCVs can be another potential sink for Mg in the ocean and since carbonates are known to fractionate Mg isotopes CCVs can regulate both concentration and isotopic composition of Mg in seawater. Besides, due to the lack of resolvable sen-sitivity of Mg isotopic fractionation in carbonates to temperature, the CCVs can also record variability in seawater ÃŽ ´26Mg. This motivates me to investigate, the ÃŽ ´26Mg of CCVs from various MOR flanks to evaluate i) their role in controlling oceanic Mg budget and ii) their potential as proxy for seawater ÃŽ ´26Mg. To fulfill the primary objective of this project I plan to 1) obtain CCV samples from various ocean basins.

Introduction The concentration of solutes in the bodily fluids of most marine invertebrates is roughly isosmotic to their environment (Raven, 2008). Because there is no osmotic gradient there is no tendency for the net diffusion of water away from the animal’s cells to occur. When a change in salinity occurs some organisms have the abilityRead MoreEffects Of The Deepwater Horizon Oil Leak On The Gulf Of Mexico1924 Words   |  8 PagesOn April 20, 2010 The Deepwater Horizon oil rig exploded and sunk into the Gulf of Mexico at Macondo MC252.
