A Study Of Lyme Disease In New

Jersey Essay, Research Paper Introduction Merely by populating in the universe, human existences are susceptible to disease. Many diseases # 8212 ; for illustration, grippe and TB # 8212 ; are spread when bacteriums or viruses pass from one individual to another. Other diseases are acquired genetically from one? s parents, such as cystic fibrosis. Some diseases, such as bosom disease and osteoporosis, develop as worlds age. Others worlds get from the environment ; illustrations are lead toxic condition and tegument malignant neoplastic disease due to exposure to the Sun. Finally, there are diseases that can be transmitted from animate beings to worlds. Lyme disease is one such disease. Cases of Lyme disease, which is transmitted to worlds and pets by the bite of a tick, are steadily increasing in countries such as the Northeast part of the United States. At present, there is no vaccinum for worlds ; the best manner to forestall Lyme disease is to take safeguards against being bitten by a tick and leting the tick to stay af filiated to the tegument long plenty for the infection to be transmitted. History The narrative of Lyme disease in the United States began in 1975, when two female parents, Polly Murray and Judith Mensch, alarmed by the great figure of instances of joint redness in the their communities of Lyme and Ease Haddam, Connecticut, contacted public wellness governments ( 7:5 ) . The wellness section contacted Allen Steere and his co-workers at Yale University, in New Haven. Steere believed the eruption may supply a hint about the infective agent or environmental toxin that was responsible for arthritis ( 2:26 ) . One early observation made by Steere was an association between the arthritis and a anterior tegument roseola. A connexion was so made between this roseola and a similar 1 called erythema migrans, which comes from the bite of the sheep tick, Ixodes Ricinus and is often found in northern Europe ( 7:5 ) . After field surveies and patient studies were carried out the research workers released three indispensable findings which subsequently led to the find of the infective agent. First, the disease was seasonal, happening most normally in the summer and much less so in the center of the winter. In geographic countries such as Connecticut, these findings suggest that the virus was either a summer virus or an infection carried by and insect or a tick ( 7:35 ) . Second, the disease did non distribute from one individual in a household to another. Summer viruses were normally spread from individual to individual, particularly those populating in the same family. When a summer virus was eliminated, the focal point shifted to the engagement of arthropods ( 7:37 ) . Third, the disease was much more prevalent on one side of the Connecticut River than the other. Since the Connecticut River bisects the province, this became an of import factor in happening the cause of the disease. The research workers found a good correlativity with the frequence of a certain tick now named Ixodes scapularis. When furthered questioned, the affected people remembered being old bitten by a tick ( 2:27 ) . At foremost, the infective agent bring forthing Lyme disease was thought to hold been either a virus, protozoon, Fungis, or bacteriums. Among the possible agents, bacterium was the highest on the list. European doctors had been handling patients with medical specialties that were effectual against bacteriums. However, these findings were non originally accepted in the United States. It was merely after some of the patients in Steere? s survey were successfully treated with antibiotics, which are effectual against bacteriums, but non against viruses, protozoon, or Fungis, that bacterium was determined to be the infective agent ( 14:1015 ) . The specific bacterium was found by Willy Burgdorfer, an expert on a assortment of tick-borne diseases. While working at Montana? s Rocky Mountain Laboratories, Burgdorfer received a cargo of ticks from New York. After looking at the contents of the ticks through a microscope, Burgdorfer found a wavy signifier of a spirochaete that had neer been seen in the Ixodes group of ticks before. After finding that the same spirochaetes were present in ticks taken from Long Island and New Jersey, the freshly named Borrelia burgdorferi was confirmed as the bacterium that caused Lyme disease ( 1:47 ) . THE VECTOR The tick that transmits Lyme disease is called Ixodes scapularis. In the northeasterly and north-central United States it is frequently called the? cervid tick? because it is found so often on cervid. The southern signifier of I. scapularis is normally called the? black legged tick. ? The southern signifier of the species poses less of a menace of infection. Fewer of the southern ticks are infected and they tend to feed on other carnal hosts instead than worlds ( 2:43 ) . The ticks that transmit Lyme disease by and large live about two old ages. I. scapularis larvae, which are non much larger than the period at the terminal of this sentence, hatch in the summer from eggs laid by the grownup female that spring. They normally feed on a field mouse or other gnawer host that summer and into the early autumn. The larvae so alteration into nymphs the first twelvemonth ; these nymphs base on balls through the winter without feeding. the undermentioned spring and summer the nymphs provender on a gnawer or other little animate being. At least three out of four Lyme disease instances in the United States are from the bite of a nymphal tick that occurs sometime between May and August. Most of the bites go unnoticed because the nymphs are so little # 8211 ; about the size of a poppy seed ( 2:45 ) . In the 2nd twelvemonth, the nymph alterations to an grownup after feeding. The larger ticks, particularly the females, are more likely to be noticed by people. I. scapularis grownups bite cervid and other big mammals, such as worlds. The grownups feed subsequently in the twelvemonth than the nymphs and larvae and may stay active even as temperature bead to merely above nothing in the late autumn. Lyme disease infection happening in the autumn, particularly in the nor-east, can normally be attributed to the bite of an grownup ( 2:45-46 ) . Reservoir The Lyme disease spirochaetes can stay active and even multiply inside a tick? s organic structure, but rarely are they passed from an grownup female to her offspring. In order for the spirochaetes to distribute in nature, an septic tick must feed on another animate being, thereby go throughing the spirochaete from that animate being to other feeding ticks. Many types of mammals and birds are capable of hosting the bacterium and of go throughing it on to other ticks, therefore finishing the vector-reservoir-vector rhythm. Because about 99 per centum of the larvae of I. scapularis do non transport the bacteriums even if their grownup female parent of male parent did, the larvae must get the bacteriums by feeding on an septic host. In the instance of cervid ticks this host is normally a wild field mouse, called Peromyscus leucopus. In some parts more than half the mice are infected with Lyme disease bacteriums, therefore supplying a uninterrupted reservoir of the spirochaetes for many ticks. In bad countries for Lyme disease, such as New Jersey, the opportunities that a larva will go septic is as least one in four ( 13:36 ) . Symptom The first mark of the disease in 60 to 80 per centum of the instances is a roseola # 8211 ; a ruddy splodge or bull? s oculus form, frequently no more than 2 1/2 inches across. If left untreated it may, in two hebdomads to a month, expand to four times that size. The roseola does non ever occur at the site of the bite ( 11:9 ) . Often it is found at the axilla, inguen, or the dorsum of the articulatio genus. However, in many instances of Lyme disease no roseola occurs ; therefore it may be necessary to look at other factors before doing a diagnosing ( 16:41 ) . Other common symptoms include icinesss, febrility, weariness, and other flu-like symptoms ( 1:47 ) . If left untreated, the disease spreads to other P humanistic disciplines of the organic structure, and frequently consequences in more joint, tendon and musculus hurting, partial facial palsy, and bosom palpitations ( 8:11 ) . Chronic symptoms can develop if the disease goes untreated for months or old ages, and leads to severe arthritis and neurological jobs ( 5:29 ) . Diagnosis The best manner to get at or except a diagnosing of Lyme disease is to analyze three facets of the patient. The first is to find if the patient exhibits any of the above symptoms. The 2nd is discover whether or non the patient is at a high hazard of undertaking the disease. This factor takes into history the environment in which the patient lives, works, or enjoys his recreational activities. It may besides include whether or non the patient has a pet that may hold brought the ticks into the house ( 16:41 ) . The 3rd factor to see before naming Lyme disease is to execute research lab trials. The Second National Conference on Serologic Diagnosis of Lyme Disease recommends a two-test attack to find an active disease or a old infection. A doctor should execute a sensitive enzyme immunochemical assay ( EIA ) or immunofluorescent check ( IFA ) . If a patient trials positive on an EIA or IFA so the doctor should follow up with a standardised Western immunoblot ( 15:937 ) . Treatment In its early phases Lyme disease can easy be treated. Clinical surveies have shown that a 10 twenty-four hours to three hebdomad class of antibiotics is about 95 percent effectual in extinguishing the disease ( 14:1015 ) . Amoxicillin and Vibramycin are the two most prescribed antibiotics. They replaced the earlier interventions of penicillin and Achromycin because they are more easy absorbed by the enteric piece of land and require less frequent dosing ( 9:1 ) . Erythromycin, which is less effectual than penicillin or Achromycin, is now merely used in the intervention of immature kids, pregnant or nursing adult females, and those people allergic to penicillins ( 2:166 ) . If left untreated and allowed to come on to a ulterior phase, Lyme disease may necessitate to be treated with endovenous antibiotics. The success rate at this phase drops significantly and frequently patients will go on to see chronic symptoms ( 2:167 ) . Prevention It is of import to be cognizant if you live in or are going to a high hazard country. Ticks thrive in wooded, shaggy, grassy home grounds, and peculiarly in shady and damp countries. Measures to forestall Lyme disease include have oning long arms and bloomerss when out-of-doorss, inserting bloomerss into socks, and utilizing repellants # 8211 ; permethrin ( sold as Permanoe ) on vesture, and diethyltoluamide ( DEET ) on exposed countries of tegument. The most of import agencies of bar is a complete review of the organic structure at the terminal of every twenty-four hours spent out-of-doorss. A tick must be attached to the organic structure for a lower limit of 24 hours in order to convey the disease ; hence if a tick is found upon review it is non excessively late to forestall the disease from being transmitted. If a tick is discovered embedded in the tegument it should be removed instantly by hold oning the organic structure with a brace of all right tipped pincers and drawing gen tly until the tick comes out ( 4:31 ) . Statistical ASPECTS In 1995 ( the last complete twelvemonth for which figures are available ) , there 11,603 instances of Lyme disease reported in the United States by 43 provinces and the District of Columbia. The overall incidence of the disease was 4.4 per 100,000 people. This was the 2nd highest one-year figure reported since the disease was first tracked in 1982, nevertheless it was an 11 % lessening from the 13, 043 instances reported in 1994 ( 10:274 ) . Despite the national lessening, the incidence of Lyme disease in New Jersey has increased steadily since 1992, from 688 instances to 1,704 in 1995 ( 6: T-3 ) . An overall incidence of 21.1 per 100,000 people was reported ( 10:274 ) . Hunterdon County leads the province and is 2nd among the 3,300 counties in the state in the figure of instances per 100,000 occupants. In 1995, Hunterdon reported 565 instances. Morris County was 2nd in the province coverage 232 instances ( 6: T-3 ) . FACTORS CONTRIBUTING TO THE HIGH INCIDENCE OF LYME DISEASE IN NEW JERSEY The three chief factors lending to the incidence in New Jersey are the sum of cervid nowadays in the province, an increased interaction between people and cervid, and an addition in the figure of doctors naming and describing Lyme disease. The figure of cervid in New Jersey continues to turn every twelvemonth ( 17:41 ) . This population detonation means that there are more cervid for the ticks to feed on and infect. This straight relates to the addition in interaction between people and cervid. As people move into more wooded countries, they are more likely to come in contact with cervid and their home grounds. This provides an chance for the ticks to attach themselves to dress or be found in families ( 13:37 ) . The 3rd factor can be attributed to an addition in consciousness among physicians to name Lyme disease. After a significant sum of media attending given to Lyme disease in the late 1980? s and early 1990? s, physicians all of a sudden began naming the disease in more patients. As an consciousness of the symptoms and hazard factors of Lyme disease increased, doctors were better able to do a more accurate diagnosing. They were now naming Lyme disease in patients that had antecedently been untreated ( 3 ) . Decision It is inevitable that the instances of Lyme disease will go on to increase in New Jersey until more people become cognizant of the earnestness of the disease. In recent old ages, the media has been instrumental in supplying the public with pertinent information refering the symptoms and hazard factors involved in the disease. At present, there is no vaccinum protecting worlds against Lyme disease. The best manner to protect oneself against undertaking Lyme disease is to forestall a tick from holding the chance to convey the infection. 1. Accerrano, Anthony. ? Tick, tick. ? Sports Afield.

Supply Chain Integration in the Food Industry Essay

Supply Chain Integration in the Food Industry - Essay Example My first action as the new CEO would be to implement an efficient consumer response (ECR) system. As one author notes, "ECR is an approach to supply chain management which...is a managerial approach that starts with consumer demand and then gears the whole of the supply chain to responding to that demand. It is a customer-driven, demand-pull product management system..." (Gillooley and Varley 42). This method makes particularly good business sense in the retail grocery environment because it is based on supplying products by allying all of the elements of the supply chain with customer purchasing patterns. Consider, for example, how this type of SCM system would increase efficiency during the holidays. Normal sales of large, frozen turkeys are generally low during the months of January through October, but spike over November and December. A supply chain which was based on the ECR model would be integrating suppliers, distributors, and in-store inventories to minimize costs and maxim ize what can only be considered as a diminishing profit margin, e.g., the closer to Thanksgiving it gets, the cheaper the price for the birds and the more competitive the market becomes. The alternatives to this integrated approach are either to run out of inventory and lose market share, or to over-stock and suffer a negative product age issue; neither of which are profitable nor efficient. Accordingly, the ECR would be my first move as the new CEO. My second strategic focus on using supply chain integration would focus on operation and information systems. Similarly to Mr. Johnston, I know that information systems efficiency and interoperability is an important area for an SCM. Proper use of technology to maximize efficiency is well worth the investment, as demonstrated by Wal-Mart in past case studies. One reason information systems are so vital is the operational support they provide and the speed and accuracy at which they provide it. This systems integration directly addresses issues like overstocking which, in many retail businesses is costly, but in a retail grocery setting can be prohibitively expensive. As Ketzenberg and Metters note, "although all major grocers use scanner technology at cash registers...[in most stores] stock ordering is still done manually by employees visually checking shelf sets" (31). It is for this reason that I think Mr. Johnston's investment in technology is astute; and I would do the exact same thing. As the information systems are integrated and the operational aspect of inventory tracking moves from visual unit counts to a more efficient and accurate SCM system, additional benefits will be gained; the ability to interface with the ECR system noted above will permit supply chain managers to monitor the relationship between quantities ordered and sold so that accurate forecasting can bring higher efficiency, lower costs, and greater customer satisfaction. The blending of a

Malcolm Gladwells 'Blink' Essay Example | Topics and Well Written Essays - 1000 words

Malcolm Gladwells 'Blink' - Essay Example For one, Gladwell is on a sticky wicket. The techniques and reasons are too complex to explain. For another, Gladwell knows what he is talking about. And finally, everyone else knows what Gladwell is talking about. On the spur moment decision, off the cuff remarks, gut feelings, intuition, quick thinking, customarily yield positive results, oftentimes because the person making the decisions and statements know very well what is going on and the reasons behind his or her decisions. Anyone who has read 'Blink' may understand the author's core issue. In simple terms, he is talking about the power of perception. One finds it difficult to disagree with the notion that he or she has never been in a situation when an intuitive stand or decision yielded positive results. The situation may be as varied as the ones author has touched upon, viz. deciding whether a statue is a fake, deciding whether a surgeon is likely to get sued for malpractice, and deciding whether the inhabitant of a particular dorm room is likely to be conscientious. In each case on which the author has elaborated the one making the decision did so with minimum information on hand, two seconds to decide, and with formidable consequences should the decision go wrong. Dr Atul Gawande is more succinct on the issue. ... Dr Atul Gawande is more succinct on the issue. In his book, 'The Bell Curve.' he cites examples of the Cincinnati Children's Hospital and Fairview University's Hospital at Minneapolis to illustrate background, the prevalent status, and the determination to turn around from mediocre to achievements, by skilled team of doctors to improve results from below average practitioners to trail blazers. They do so without any recourse to fresh medical training. They do so with determination, discipline and professional aggressiveness to ensure patients' recovery. Gawande's point of view is that it is not only professional qualification and capabilities, but practice and personal determination to succeed that drives one to achieve feats which may otherwise look impossible. [Atul Gawande].1 Correlation and Calculation In the instances of both Malcolm Gladwell and Atul Gawande the risk factors are overwhelming and possible solutions depend on 'thin slicing' - filtering the very few factors that matter from an overwhelming number of variables. [Malcolm Gladwell].2 Normally everyone is taught not to make hasty decisions, look before leaping, think, look at all angles, don't go by feelings, and to make maximum efforts at information gathering and consultation before making a decision. However, not everyone is instructed on how to go about handling a life and death situation, a crisis, walking tightrope over the Niagara, or accompany a close relative on his or her last walk to the gallows. Moreover, it is natural to pass the buck in a crisis situation or as a last resort, leave difficult, dangerous, embarrassing, debilitating situations to the Almighty in prayer! The person facing the crisis is a lone ranger facing the most unfortunate situation in his or her life.
