Learn More About the History of Lasers

The name LASER is an acronym for Light Amplification by the Stimulated Emission of Radiation. It is is a device that emits a beam of light through a process called optical amplification. It distinguishes itself from other sources of light by emitting light in a spatially and temporally coherent manner. Spatial coherence keeps the beam within a narrow and tight path over long disances. This allows the energy generated to be used in applications such as laser cutting and laser pointing. Having temporal coherence means that can emit light within a narrow spectrum to generate a light beam of a specific color. In 1917, Albert Einstein first theorized about the process which makes lasers possible called Stimulated Emission. He detailed his theory in a paper titled Zur Quantentheorie der Strahlung (On the Quantum Theory of Radiation). Today, lasers are used in a wide range of technologies including optical disk drives, laser printers and barcode scanners. They are also used in laser surgery and skin treatments as well as cutting and welding. Before the Laser In 1954, Charles Townes and Arthur Schawlow invented the maser (microwave amplification by stimulated emission of radiation) using ammonia gas and microwave radiation. The maser was invented before the (optical) laser. The technology is very similar but does not use visible light. On March 24, 1959, Townes and Schawlow were granted a patent for the maser. The maser was used to amplify radio signals and as an ultra sensitive detector for space research. In 1958, Townes and Schawlow theorized and published papers about a visible laser, an invention that would use infrared and/or visible spectrum light. However, they did not proceed with any research at the time. Many different materials can be used as lasers. Some, like the ruby laser, emit short pulses of laser light. Others, like helium-neon gas lasers or liquid dye lasers, emit a continuous beam of light. The Ruby Laser In 1960, Theodore Maiman invented the ruby laser considered to be the first successful optical or light laser. Many historians claim that Maiman invented the first optical laser. However, there is some controversy due to claims that Gordon Gould was the first and there is good evidence backing that claim. The Gordon Gould Laser Gould was the first person to use the word laser. Gould was a doctoral student at Columbia University under Townes, the inventor of the maser. Gould was inspired to build his optical laser starting in 1958. He failed to file for a patent his invention until 1959. As a result, Goulds patent was refused and his technology was exploited by others. It took until 1977 for Gould to finally win his patent war and receive his first patent for the laser. The Gas Laser The first gas laser (helium-neon) was invented by Ali Javan in 1960. The gas laser was the first continuous-light laser and the first to operate on the principle of converting electrical energy to a laser light output. It has been used in many practical applications. Hall's Semiconductor Injection Laser In 1962, inventor Robert Hall created a revolutionary type of laser that is still used in many of the electronic appliances and communications systems that we use every day. Patel's Carbon Dioxide Laser The carbon dioxide laser was invented by Kumar Patel in 1964. Walker's Laser Telemetry Hildreth Walker invented laser telemetry and targeting systems. Laser Eye Surgery New York City ophthalmologist Steven Trokel made the connection to the cornea and performed the first laser surgery on a patients eyes in 1987. The next ten years were spent perfecting the equipment and the techniques used in laser eye surgery. In 1996, the first Excimer laser for ophthalmic refractive use was approved in the United States. Trokel patented the Excimer laser for vision correction. The Excimer laser was originally used for etching silicone computer chips in the 1970s. Working in the IBM research laboratories in 1982, Rangaswamy Srinivasin, James Wynne and Samuel Blum saw the potential of the Excimer laser in interacting with biological tissue. Srinivasin and the IBM team realized that you could remove tissue with a laser without causing any heat damage to the neighboring material. But it took the observations of Dr. Fyodorov in a case of eye trauma in the 1970s to bring about the practical application of refractive surgery through radial keratotomy.

War and Nation-Building Essay - 503 Words

War and Nation-Building The term ‘nation-building’ is often defined as evolution rather than revolution, though it can mean different things to different people. As that reason, nation-building refers to give assistance in the development of governmental basic structure, civil society and economics in a dysfunctional or unstable country in order to increase stability. Therefore, War, which may lead to civil or global confusion, does not promote nation-building. The First and Second War World is good example of showing why war does not. Economy is one of the most important elements on the development of countries, but war always destroys economy. The First and Second War†¦show more content†¦As the victorious nations, the situations of Britain and France are the same as Germany and Italy; they needed to pay a large amount for rebuilding, though their economies were destroyed during the wars. Therefore, the aftermath of the world wars led most of the world’s countries to political crisis. In the cases of these wars, we can see that war only bring ruin, not nation-building. The German Empire was the industrial giant of the world with lofty heights of political and cultural prestige by 1914, but when the World War I (1914-1918) broke out, it brought hunger and starvation to the Germans. At that time, nobody knew that the Great Depression after WWI would raise the power of Hitler and speed up the growth of the Nazi Party. The Nazification of Germany and the rise of Totalitarianism ultimately led to the outbreak of the World War II. At an early stage, Germans regarded Hitler as a ‘messiah’ who had the ability to assist Germany in the economic distress. At last, what did Germany gain after the defeat of Nazi? The answer is nothing. The history of Germany tell us leaders like Hitler who attempted to strengthen his country through war is often unsuccessful in the development of country due to the use of wrong way. Except the damage of economy, countries always suffer by large death toll in war.

Prostate Cancer Causes And Treatment Health And Social Care Essay Free Essays

string(138) " that prostatic tissue cells called â€Å" Basal root cells † are the most likely perpetrator in research lab trials done on mice\." This paper will look into several different academic diary articles and some popular media articles that are about prostatic malignant neoplastic disease. These articles discuss prostate malignant neoplastic disease causes, ( conjectural and known ) , sensing methods, and intervention options. A twosome of the articles besides focus on the cost of intervention for patients, every bit good as the hazards involved with the differing methods of intervention. We will write a custom essay sample on Prostate Cancer Causes And Treatment Health And Social Care Essay or any similar topic only for you Order Now Several intervention options for prostate malignant neoplastic disease are still being studied. This essay will critically analyse and compare prostatic malignant neoplastic disease sensing methods, ( such as Prostate-specific antigen or ( PSA ) trials ) intervention options, and the differing success or failure of each method, every bit good as concentrating on the increasing cost of intervention that patients are forced to pay. Some of the articles besides suggest that more resources and more instruction are needed to assist take down the mortality rate from prostate malignant neoplastic disease. This paper will research what is being done to assist take down the mortality rate every bit good as what is being done to assist increase the rate of early sensing of prostate malignant neoplastic disease. Keywords: Prostate-specific antigen Prostate Cancer: Causes and Treatment Options Available in Today ‘s Scientifically Advanced Society Harmonizing to the Prostate Cancer Foundation, prostate malignant neoplastic disease occurs when cells within the prostate grow uncontrollably, making little tumours. The term â€Å" malignant neoplastic disease † refers to a status in which the ordinance of cell growing is lost and cells grow uncontrollably. Prostate malignant neoplastic disease is a disease of epidemic proportions. 1 in 6 American work forces will be diagnosed with prostate malignant neoplastic disease and new instances are diagnosed every 2.7 proceedingss ( Charles 2009 ) . As prostatic malignant neoplastic disease airss such a menace to work forces worldwide, more clip and money should be spent to better upon the bing methods and engineering every bit good as invested towards instruction and consciousness plans. The fact that these statistics are existent is why prostatic malignant neoplastic disease consciousness and instruction is so indispensable because many deceases could hold been prevented if the in stances had been detected at earlier phases of the malignant neoplastic disease. Prostate malignant neoplastic disease ‘s specific cause is still unknown, nevertheless scientists hypothesize that cistrons play a function, because the hazard factor for acquiring prostatic malignant neoplastic disease is well higher if you have a household history of it. The two chief methods used for prostate malignant neoplastic disease testing are rectal scrutinies and prostate-specific antigen ( PSA ) blood proving. Rathus, Nevid, and Rathus ( 2008 ) remind work forces 50 old ages and older that the American Cancer Society recommends that work forces receive one-year rectal scrutinies and PSA blood trials. Treatment methods for prostate malignant neoplastic disease are limited, but new engineering has allowed for a higher endurance rate because of early sensing. The first point of involvement is that the costs of prostatic malignant neoplastic disease intervention have gone up well in the last 20 old ages harmonizing to USA Today reporter Lisa Szabo. In her article entitled â€Å" Patients bear brunt as malignant neoplastic disease disbursement hits $ 90 billion † she discusses how â€Å" these lifting costs have been driven by forces such as new drugs, robotic surgeries, and radiation techniques † ( 2010 ) . In her findings she discovered that from 1991 to 2002 the cost of intervention for malignant neoplastic disease doubled. â€Å" These additions are unsustainable † claims John Seffrin, CEO of the American Cancer Society. Because of the increasing costs of intervention the American Cancer society can merely assist 1 out of 6 patients as opposed to in the yesteryear when they were able to assist 1 in 5. When one takes into history how many malignant neoplastic disease patients are in the United States, so they can rec ognize how many people are waiving intervention because they are uninsured and can non afford intervention. It is tragic that the rise costs are ensuing in preventable deceases. In another article reviewed, Krahn, Zagorski, Laporte, Alibhai, Bremner, Tomlinson, Warde, and Naglie, ( 2009 ) set out to detect health care costs in relation to prostate malignant neoplastic disease. They researched direct medical costs for around 42,000 work forces over the patterned advance of the disease. The costs they found were between $ 2,000 to around $ 16,000 dependant on where the single patient was in the intervention procedure and how advanced their malignant neoplastic disease was. The ensuing decision was that prostatic malignant neoplastic disease costs â€Å" are highest around two events, malignant neoplastic disease diagnosing and malignant neoplastic disease decease † ( Krahn et Al ‘s. 2009 ) . The 2nd point of involvement is that drug company Roche ‘s â€Å" Avastin † a prostatic malignant neoplastic disease drug late hit headlines and non in a good manner. Harmonizing to the Wall Street Journal, Roche Holdings released a statement that said that Avastin had failed in late phase prostate malignant neoplastic disease tests. This intelligence was non good for shareholders who are estimated to hold lost jutting gross revenues of 7.48 billion dollars. The other bad intelligence is that people who have been utilizing Avastin an antibody for intervention of malignant neoplastic disease, are besides paying for something that is non every bit effectual as they have been lead to believe. The 3rd point of involvement is that although scientists know what causes malignant neoplastic disease, new stairss are being made to detect what specifically causes prostatic malignant neoplastic disease, and other types of malignant neoplastic disease. In an exciting article in Science News, writer L. Sanders reviews a new survey that suggests likely links between â€Å" self-renewing root cells † and prostatic malignant neoplastic disease ( 2010 ) . The survey suggests that cistrons are the perpetrator. â€Å" Think approximately malignant neoplastic disease as a disease of root cells, Mutants in these cells can do normal root cells to lose their regularized behaviour and alternatively turn into an inchoate malignant neoplastic disease † ( Sanders 2010 ) . The research workers besides found that prostatic tissue cells called â€Å" Basal root cells † are the most likely perpetrator in research lab trials done on mice. You read "Prostate Cancer Causes And Treat ment Health And Social Care Essay" in category "Essay examples" In all the research they have done, â€Å" Basal root cells are what drives the malignant neoplastic disease, irrespective of the type of mutant † says Owen Witte, a research worker at the University of California. â€Å" A specific cistron called Bmi-1 plays a important function in â€Å" Basal root cells † reclamation procedure, when Bmi-1 activity was reduced, the cells were no longer able to self renew, nor did they organize tumours † ( Sanders 2010 ) . The 4th point of involvement is that surveies show household history of prostate malignant neoplastic disease as one of the taking hazard factors associated with prostate malignant neoplastic disease. As Damber and Aus ( 2008 ) discovered while researching prostate malignant neoplastic disease, household history is a big factor when measuring 1s single hazard factors. They hypothesize that one evident ground for this is that cistrons are passed down biologically from male parent to boy. They besides believe that the malignant neoplastic disease doing cistrons mutate, but the ground ( s ) why are still unknown. Harmonizing to the text edition writers, Rathus, Nevid, and Rathus ( 2008 ) devouring high sums of animate being fats has been shown to increase 1s hazard of acquiring prostatic malignant neoplastic disease. They besides discuss how the opportunities are higher in black males than in white males. One thing Damber and Aus ( 2008 ) did note in their survey was that the figure of instances of prostate malignant neoplastic disease was higher in work forces in urbanised states as opposed to Asiatic work forces. The ensuing surveies showed that lifestyle differences every bit good as exposure to radiation were the grounds for the different statistics between Asiatic work forces and those in more urbanised states. They besides discuss how PSA and other showing methods are still being studied excessively analyze merely how effectual they really are. Once work forces are suspected of holding prostate malignant neoplastic disease, the most common method of diagnosing is a biopsy which is surgically taking a little part of the suspected tumour for proving. Most patients once they are diagnosed with the disease, are concerned with how concentrated the malignant neoplastic disease is, because it is this factor more than any other that determines how long they have to populate. â€Å" In other words, the disease establishes the forecast more than the pick of intervent ion. † ( Damber and Aus 2008 ) Treatment methods are varied and all have hazards involved, but as the writers pointed out, most intervention programs are based on factors such as the PSA figure, ( how high or low ) the degree is, the size and arrangement of the tumour, every bit good as the patients single life anticipation. Treatment plans besides vary depending on if the malignant neoplastic disease is localized to merely the prostate, or if it has advanced ( grown ) within the prostate, or if the cancerous cells have spread to other parts of the organic structure more serious intervention options will be considered. Damber and Aus ( 2008 ) speculate that intervention methods for both localized and advanced prostate malignant neoplastic disease will stay the same for the clip being. The 5th point of involvement is the existent intervention processs that are presently used. Harmonizing to K. Charles in her article about prostate malignant neoplastic disease in the Daily News, NY, she discusses the three major ways to handle prostatic malignant neoplastic disease. Surgery, external beam radiation, and radioactive seed implant therapy. A 4th new and extremist intervention option is known as â€Å" active survellaince, which is fundamentally making nil but invariably supervising the malignant neoplastic disease. She discusses in her article that physicians have non yet been able to make up one’s mind which intervention option is more effectual than another, as they say that the consequences of each intervention option vary instance to instance. These discrepancies besides depend on how progressed the malignant neoplastic disease is and how healthy the patient was before they got malignant neoplastic disease. The 6th point of involvement is a possible prostate malignant neoplastic disease intervention that is still being researched called Cryotherapy. In an article by A. Gardner, she discusses how several prostatic malignant neoplastic disease patients had successful cryoblation and their tumours were successfully thwarted. The method is still in research nevertheless, and as Dr Debra Monticciolo said, â€Å" The construct is good, but we need a bigger survey with longer follow up. It takes a piece for a twosome of tumour cells left behind to garner adequate steam to be noticed † ( Gardner 2010 ) . One of the most controversial methods of intervention is to make nil and merely look into in on the malignant neoplastic disease often, to guarantee that it has non grown or spread. In an article by Johnsun and Treurnicht, they claim that, â€Å" The bulk of work forces with low-risk prostate malignant neoplastic disease will decease of unrelated causes † ( 2009 ) . They besides d iscuss how this newer method of intervention, officially known as â€Å" active surveillance † challenges the old method of radiation, and alternatively speculate that attentive non-action, with merely minimum interventions is perchance more effectual. Johnsun and Treurnicht researched a group of 549 malignant neoplastic disease patients who were offered â€Å" active surveillance † or surgery. The patients chose the surgery. Over an 8 twelvemonth clip span, it was discovered that the lone manner to guarantee if â€Å" active surveillance † is an effectual method of intervention is by perennial surveies of work forces who have had biopsies. In another article I reviewed, writer R. Lane and C. Metcalfe looked into a survey that is being conducted in the UK. The survey is a â€Å" randomised controlled test measuring different prostate malignant neoplastic disease interventions † ( 2008 ) . In the article, they claim that repetition PSA testing is one of the most effectual methods for make up one’s minding if one needs surgery. Harmonizing to the article, work forces whose Prostate specific antigen degrees are between 3.0 and 19.99 ng/mL are all campaigners for intervention and most likely, a biopsy. Besides harmonizing to Lane and Metcalfe, in the test referred to in the article, the participants were between 50 and 70 old ages old. The decisions of the writers was that â€Å" reiterate PSA blood testing, peculiarly in work forces aged lt ; 60 old ages, may assist place those with high hazard malignant neoplastic disease who would profit from aggressive intervention, every bit good as forestalling over-di agnosing work forces with clinically undistinguished disease and avoiding biopsy in those with no malignant neoplastic disease † ( 2008 ) . The 7th point of involvement in respects to Prostate Cancer sensing methods is the struggle over PSA proving and its accurate consequences, or is it every bit accurate as one would trust? Nogueira, Corradi, and Eastham ( 2009 ) explore other biomarkers besides PSA trials. They believe that â€Å" although PSA is the best malignant neoplastic disease biomarker available, it is non perfect. It lacks both the sensitiveness and specificity to accurately observe the presence of prostate malignant neoplastic disease † ( Nogueira et al. , 2009 ) . In their article, they evaluate the advancement that is being made towards being able to utilize freshly discovered biomarkers to assist screen for prostate malignant neoplastic disease. The surveies that they review show that Human Kallikrein 2 or ( hK2 ) is a serine peptidase that is closely related to PSA in sequence. The surveies have revealed nevertheless, that ( hK2 ) is non ready to be used yet as it can bespeak that there are malign ant neoplastic disease cells active in the blood, but non accurately plenty. This is similar to the job that research workers run into with PSA proving. Several other membrane antigens and antibodies are besides being studied, but none of them are yet ready to be used as farther research and testing is still needed. In the text edition, Rathus, Nevid, and Rathus ( 2008 ) agree with this article that PSA testing is the best method available. This should non be seen as though no advancement has been made nevertheless, because as Dr. Richard Stock said, â€Å" The past 40 old ages have seen a revolution in prostatic malignant neoplastic disease intervention. Not merely are 90 % of instances caught before they metastasize, but physicians have immensely improved engineering for contending malignant neoplastic disease in the other 10 % of patients † ( Charles 2009 ) . The 8th point of involvement is the recent intelligence that the American Cancer Society has released new guidelines on prostate malignant neoplastic disease showings. In the article by A. Gardner, it discusses how the American Cancer Society is now seting less accent on everyday PSA testing and more accent on doctor-patient conversations and determinations. These new guidelines are issued as a consequence of research and the on-going struggle over how accurate PSA proving truly is. Harmonizing to a statement issued by the American Cancer Society, â€Å" work forces with no symptoms of prostatic malignant neoplastic disease who are in comparatively good wellness and can anticipate to populate another 10 old ages should do an informed determination with their physician about prostate malignant neoplastic disease showing after larning the uncertainnesss, hazards, and possible benefits associated with such showing † ( Gardner 2010 ) . These new statements disagree with with what Rathus, Nevid, and Rathus ( 2008 ) , province in the text edition, â€Å" The American Cancer Society recommends that work forces receive one-year digital rectal scrutinies get downing at the same age as PSA trials † ( Rathus et al. 2008 ) . They are now proposing that PSA proving should non be a demand for all work forces over 50. The 9th point of involvement, nevertheless, is that many agree that PSA testing is still non a really dependable or effectual method of sensing. In an article in Practical Nurse, urologist Professor Roger Kirby, manager of the Prostate Centre in London, states that, â€Å" PSA testing is enormously controversial because the figure of false positives and lost diagnosings of prostate malignant neoplastic disease generated by the trial raises inquiries about its utility † ( 2009 ) . In the article Kirby besides points out that although PSA testing is so unelaborated, that unluckily work forces do non hold many other options for sensing. He calls for more research into alternate proving methods for the presence of cancerous cells in 1s blood. He besides calls for more instruction among work forces, to do them aware of their hazard of undertaking prostate malignant neoplastic disease. Personal instruction and personal consciousness are cardinal elements in contending the mortality rate of prostate malignant neoplastic disease. The 10th point of involvement is the advancement being made towards educating the populace on prostate malignant neoplastic disease. In the European Journal of Cancer Care, lending writer S. Bowen, discusses a public wellness plan in Ireland called the National Cancer Information Service. It was developed because of the National Cancer Forum ‘s, â€Å" concern that high quality, accurate information and resources should be available to the populace † ( Bowen 2010 ) . The bulk of people who called in to the service concerned about prostate malignant neoplastic disease were work forces in their 50 ‘s to mid 60 ‘s. The service besides found that most work forces were naming to happen out how and where to acquire screened for prostate malignant neoplastic disease. Bowen thinks this is due to non adequate public consciousness of prostate malignant neoplastic disease, he believes that, â€Å" as the public becomes progressively cognizant of malignant neoplastic di sease, it is of import that they have entree to unclutter indifferent information from a responsible quality service informed by ongoing rating † ( 2010 ) . Overall, the popular media articles that I reviewed did look to hold with the academic diary articles. In respects to the cost of prostatic malignant neoplastic disease intervention, the text edition did non truly travel into deepness on the subject, but the two articles that I reviewed did look to hold with the consensus that prostatic malignant neoplastic disease intervention is expensive, and that the cost of intervention is lifting. Another issue that I reviewed was besides non truly covered by the text edition, but the article that I reviewed was converting in that it shows that more research is needed for prostate malignant neoplastic disease drugs. Another issue that I reviewed was besides non covered by the text edition, but I found it intriguing that scientists are coming so near to happening a manner to bring around malignant neoplastic disease. Another issue I reviewed was agreed upon in my text edition, the academic article and the popular media that risk factors for pros tate malignant neoplastic disease are pretty consistent. Another issue that I reviewed was the existent processs which did hold with my text edition. Another issue I reviewed was Cryotherapy, which is an experimental method, non covered in the text edition. Another issue was conflict over PSA testing, and I found that the academic and popular media did hold chiefly when it came to this issue. I do non experience that anything was left out in these articles or the text edition. I did experience that the academic surveies were and are legitimate. I believe that future surveies should concentrate on prostate malignant neoplastic disease sensing and intervention. The articles that I reviewed were really assuring as they show that a batch of advancement has already been made in mention to prostate malignant neoplastic disease intervention and sensing. I think that scientists and research workers should go on what they are making, particularly with the research on root cells and their direct connexions to malignant neoplastic disease. I think that happening the cause of prostate malignant neoplastic disease should be the figure one precedence of research workers. I besides feel that happening the future remedy to malignant neoplastic disease can merely be done if much more extended root cell and cistron research is conducted. Until that remedy is found howver, I believe it is of import to concentrate today ‘s research on happening more accurate methods of proving, as PSA blood testing has been shown clip and clip once more to non be every bit dependable as medical professionals would wish it to be. The new findings that I discussed are rather exciting though, and the possibility of happening a 100 % accurate trial for cancerous cells in the blood stream is most likely shortly to be a world. The find of a new and more accurate testing method for prostate malignant neoplastic disease would assist increase the figure of subsisters every bit good as lessening the figure of false readings and incorrect diagnosings. I feel that the of import message throughout the articles and research that I conducted is that work forces need to be more educated and more cognizant of prostate malignant neoplastic disease and its symptoms and that physicians need to pass more clip with their patients who are diagnosed with prostate malignant neoplastic disease. I think that households with a history of prostate malignant neoplastic disease demand to hold father-to-son treatments about prostate malignant neoplastic disease and that they might desire to cut down on their consumption of carnal fats and their exposure to radiation as that raises their hazard. Black work forces who consume a batch of ruddy meat with a household history of prostate malignant neoplastic disease should be particularly concerned. The other of import thing is that work forces who are diagnosed with prostate malignant neoplastic disease demand to be informed of all their options, non merely the options that benefit and are profitable to th e medical establishment supplying the intervention, or the drug company supplying the drugs for intervention. The new â€Å" active surveillance † prostate malignant neoplastic disease intervention method is still under examination as to whether it is every bit effectual as medical professionals are trusting it will be. I besides think that reform is needed in respects to the hideous cost of intervention, which for the mean individual, is really difficult to afford. The general public needs to be more cognizant and educated ; more societies such as the American Cancer Society are needed to assist raise consciousness and to supply valuable information, resources, and support to those who are affected. The fiscal load on those with prostatic malignant neoplastic disease is besides something that needs to be addressed. The hereafter of prostate malignant neoplastic disease is one that is difficult to foretell nevertheless, because cancerous cells and cistrons are invariably mutating and altering coevals from coevals. The sheer sum of clip, money, and resources that have been put into malignant neoplastic disease research and interventions is unbelievable. I think that the hereafter of prostate malignant neoplastic disease will hopefully be cut short by the find of a manner to forestall the cancerous cells from mutating, whether it is from radiation, antibodies, or remotion of the cancerous cells. I besides feel that the of import message to anyone reading this is personal duty and personal consciousness and instruction. It is non groups such as the American Cancer Society ‘s duty to educate and assist those who are contending prostate and other signifiers of malignant neoplastic disease, it is the person ‘s duty to make all that they can, within ground, to forestall and observe malignant neoplastic disease early, before it is excessively late. Fear, cunctation, ignorance, and deficiency of wellness attention and coverage are large issues when it comes down to the truth. The fact of the affair is that many people who are deceasing and have died from prostate malignant neoplastic disease could hold been saved if they had detected it earlier.

Critical Appraisal Breast Cancer

Question: Discuss about theCritical Appraisalfor Breast Cancer. Answer: Introduction Around 1.7 million women across the world were reported of breast cancer in the 2012. Around 521,900 women died because of this disease. This disease is affecting women all across the world. (Torre et al., 2015). Breast cancer is one of the most common cancer affecting women. It occurs due to the uncontrolled and abnormal growth of cells in the breast. (Peacock, 2001). It leads to the formation of tumour. Tumour formed in the breast may benign or malignant. Benign tumours are lumps formed in the breast but they are not cancer as they do not spread to the other body organs. Malignant tumours are cancerous as they tend to spread to the other body parts and affect them. (American Cancer Society, 2016). As per the reports from USA, the survival rate of women suffering from breast cancer is 90%. Around 2.9 million women are reported to have survived breast cancer in USA. The major reason for this disease is the bad life style. (American Cancer Society, 2013). The treatment applied to cure the disease involves surgical methods, chemicals interventions, radiotherapy and hormonal therapy. The methods are effective against but may pose adverse health issues. (Heisig et al., 2016). There is a possibility of acquiring Lymphedema which is a severe chronic disease as a result of the side effects. This is observed in around 40% of women who undergo the breast cancer surgery. (McLaughlin et al., 2013). Lymphedema Due to Breast Cancer Lymphedema related to breast cancer occurs due the blockage or disrupted lymph system because the adverse effect of cancer treatment. In this disease the soft tissues get filled with fluid rich in protein mainly due to the disruption in the lymph flow. (Armer Stewart, 2010). This disease mainly targets the limbs but can also affect the genital area, head, neck, lungs and the abdomen. (Gary, 2007). The disease is observed mostly in 2 years after the surgery, although the onset can be different in different women. (Paskett et al., 2007). Disease Pathology Lymphatic system in human body is responsible for maintaining the fluid level in the various tissues and has major role in the removing the pathogens infecting the human body. It is an independent system which has important role in maintaining the immunity of the body. (Wanchai et al., 2016). Due to the accumulation of the larger molecules in the lymphatic vessels, transportation of lymph is obstructed. A high osmotic pressure is generated which increases the fluid level in the interstitial tissues space and leads to the condition known as lymphedema. (Foldi et al, 2006). Symptoms and Risk Associated with Lymphedema The common symptoms reported in the patients after breast cancer surgery are- swelling in limb, stiffness, pain, weakness, muscle fatigue, trouble in moving the limb etc. these symptoms act as sign to the development of lymphedema in the women post breast cancer surgery. The swelling in limb increases with the severity of the disease. As per some of the studies conducted on the breast cancer patients, the diagnosis of change in the volume of limb has increased following the report of pain, swelling and stiffness of the limb by the breast cancer survivors. (Cormier et al., 2009). This disease affect the quality of life of the breast cancer patients and also pose psychological problems. (Fu Kang, 2013). The effect of surgery on the axillary node, exposure to radiation leads to the low lymph flow in axilla and retention of fluid in the tissues. Radiation exposure poses a threat on the functioning of the lymph vessels. Obesity and the cancer development again can also cause lymphedema. (Avraham et al., 2010). Treatment Methods The health care professionals suggest their patients to follow a self care regime after the breast cancer surgery. This can help in the preventing the disease. Some of the common precautions are taking care of skin, using compression undergarments, avoiding muscle damage, obesity control, following a light aerobic exercise regimen every day. Treatment methods will based on the stage of cancer diagnosed, the body mass index of the patient, normal health of the patient. Although this disease has no cure as it is a chronic infection. The preventive method and other suggested method could help in dealing with it and minimising the effect. (Greene et al., 2015). A number of researches conducted on how to control the symptoms. One such study was conducted by Jeff and Wiseman (2012) on the effect of routine exercise along with the self care methods to control the lymphedema in women after breast cancer surgery. The Background of the Study The experiment was designed to observe the effect of exercise on women suffering from the breast cancer related lymphedema. This study was conducted on a smaller level before applying it on a broader level. The duration of the study was about 6 months comparing the effect of standard lymphedema self care to the normal self care alone. The observation was based on the change in volume of the limb after the 6 month following the researchers guideline. Also observation was made on the change in the quality of life, the functioning of the arm and effect on the shoulder movements. Critical Analysis of the Study Introduction- the introduction of the article discusses about the effect of the disease and the number of researches going on to find effective exercises to help the women who are suffering with lymphedema. It mentions to the lack of effective exercise to help in this disease. This is true in case of disease as the proofs are less in case of this disease to justify the role of exercise. (Schmitz et al, 2009). The author justified using several references about the lack of proper research related to the topic. Method-The study was a controlled trial in 6 month, conducted in a cancer centre in England. The study aim on getting not more than 70 women as it was a limited trial but only 23 women participated who were fulfilling the criteria of the research. These women were randomly allocated the group which included A standard self-care alone i.e. the control group (CG) or the standard self- care along with exercise i.e. the intervention group (IG). Previous medical treatment were to be followed during the trial that was related to the skin care, compression undergarment, use of gloves etc. the prescribed exercises were also allowed. The number of participation was less compared to the desired number. This can affect the result as with fewer numbers of participant chances of getting positive result is less. The categorical isolation was well established and all the necessary information was considered. The previous medications and nursing interventions were allowed which was necessary for the response. The exercises included in the trial were mild and gravity resistive (Leduc et al., 1981). The exercises were based on deep breathing, gravity-resistant arm exercises focusing on the flow of the lymph in the limb. The participants were asked question on their regularity with the exercise regimen. The change in the volume of limb, body weight and the shoulder movement were recorded before starting trail and after 4th, 12th, and 26th week. The analysis methodology was well selected with the correct exercises. The exercises chosen are mild which is important as harsh exercise can cause ill effect on the participants health. Instrument selection-The quality of their life was also measured. The technique involved for the measurement included Perometer 350S which measured the change in limb volume. Using this instrument the mean volume was calculated for both arms and relative excess limb volume percent was calculated. Lymphedema specific 28- item was used to analyse the change in quality of life. The functional activity of the patients was measured by the QuickDASH-9 questionnaire. A goinometer was used to measure the shoulders range extension. Analysis was done following the SPSS version guidelines. The value of significance was set at p The researcher has effectively applied the various instruments which are necessary for the research. The guidelines are followed and the limb volume before the trial is measured. They have given the instruments role and used it effectively. The interventions are described. The chart depicts the measures to explain the protocol guidelines. Results- At the end of the study it was observed that all 23 participants followed the trail method. The effect of the different routine was same when observed at baseline. The changes in the limb volume were observed on the 12th week with a reduced limb volume in both the groups whereas no significant change was observed after the 26th week. There were no changes in quality of life and the range of the shoulders extension. The study showed a positive result with the reduction in volume of fluid in the limbs. The reduction in the intervention group was by 6.4 and in the control group was by 2.49. This shows that exercise has a positive impact on management of lymphedema in women. The method followed by the researchers was as per the guidelines mentioned for the analysis and all the points were taken into consideration. The researchers have mentioned all the necessary information and the techniques that were involved. Discussion- The randomisation of the trail is also well established owing to the lesser number of participants. They included all the major effects under the observation criteria. The calculations have been mentioned. The results predict the effect clearly and not vague. The researchers also considered the ethical issue related to the study. They maintained that they were blind to the randomisation. The patients were examined routinely with proper interactions. They were also observed on the basis of changes in the quality of life and what was the impact of the previous medical suggestion that they were following. Both the groups were analysed equally. The participants selected were observed to have a history of at least 3 months suffering with lymphedema. They got the positive results considering the small number of participants. the observed the benefits of the method and ready to continue it to avail the relief from the disease. The only negative point with study is the small number of women. As it is a small cohort of women, the results cannot be applied on the clinical level and also the duration was less. They have mentioned that extending the period was not required. Although considering a small cohort it would be better if they considered the study for a longer duration. The suggestion by the researchers to apply it on clinical level is not correct because the number of women is less. Future research- Although the effect analysed were positive, the implication was on limited women. Thus its effectiveness on the clinical level should be considered only if the results are positive for a large cohort of women. It is necessary to develop effective technique to measure the effect of the disease using proper technique. Development of effective tool is important. The future aspect of the research should be based on the implication of method on more number of women. It should be on applying various techniques and identifying the most effective exercises to manage the disease. Conclusion As there is no possible cure to lymphedema, it is important to discover methods to reduce the effect of the disease. The study was conducted followed the effect of exercise standard for the lymphedema with the self exercise. The researchers have conducted the study considering all the important issues and following all the important guidelines. Considering the interest of the disease on the women, it is sad to observe that not many women turned up for the trial. To formulate effective methods it is important that more number of women take part in the research and cooperate with the method. References Torres et al. (2015). Global Cancer Statistics, 2012.
