A policy brief - Essay Example The company has implemented initiatives aimed at conserving environmental policy by reducing waste. The petroleum industry has been under scrutiny by the international community for its contribution to the emission of greenhouse gases. Petroleum products are also non-renewable hence the exploitation of these products could lead to the depletion of resources for future generations. A major environmental risk posed by the company is oil spills into the ocean which results in water pollution and suffocation of sea life. During the fractionation process to manufacture petroleum products, some of the byproducts of the process that are released into the environment such as sulphides and carbon dioxide contribute to the greenhouse effect. The company should develop methods of reducing emission of these wastes into the environment by exploring alternative waste management methods. The implementation of green energy in a petroleum industry can be quite an expensive venture. To mitigate losses due to the increase cost of manufacture of petroleum products would have a direct impact on the price of petroleum products. The company should revise its policies to include reducing the emission of greenhouse gases such as carbon dioxide and chlorofluorocarbon which contribute to the greenhouse effect. They should also consider integrating the use of natural sources of energy such as solar, wind and tides to reduce their reliance on electricity and promote biodiversity. Further, the company should educate its workers on the need to preserve the environment by adopting recycling and techniques of proper management of

The theory of wound care fro Podiatry Essay Example | Topics and Well Written Essays - 2000 words

The theory of wound care fro Podiatry - Essay Example They may be chronic or acute, and open or closed. The patient presented with a full thickness ulcer measuring 8 mms in diameter of approximately 6 months duration and the tissues around the ulcer are acutely inflamed. Patients with rheumatoid arthritis may develop leg and foot ulcers of varied aetiologies, including venous disease, infection and inflammation. The foot ulcers in rheumatoid arthritis patients may involve several of these aetiological factors and are often difficult to heal (Sunita). Both the ulcers and the treatments are often painful, and these ulcers may be present for years. Chronic wounds plague more than 10 million people in the world today. But even more troubling is the fact that these wounds may persist for months and even years without any healing or sign of improvement (Morgan 25). The problem is usually, if not always, not the wound itself; and therefore treating the wound will not, in chronic cases, resolve the issue. Chronic wounds have underlying causes t hat must be addressed in order for the wound to heal properly. Because normal skin and wound care is not enough to heal these wounds they usually remain for extended periods of time. As a rule, only 50% of leg ulcers heal within 4 months of appearing, 20% remain open at 2 years and 8% remain open at 5 years (World Wide Wounds). So we see that to effectively treat a chronic wound you must treat the cause and not simply treat the symptom. There are several factors that affect wound healing. These include the age of the patient, hydration status, presence of infection, presence of underlying conditions, medications, obesity, oxygenation and tissue perfusion, personal hygiene and nutrition (Bowler 499). In the case of Mrs. Freeman, these factors can be very well correlated. The physiological changes that occur with ageing place older patients at higher risk of poor wound healing. The age of the patient places her in a relative state of immune deficiency. The immune system also declines with age making older patients more susceptible to infection. Older people can also present with other chronic diseases, which affect their circulation and oxygenation to the wound bed. Dehydration leads to an electrolyte imbalance and impaired cellular function. The presence of infection can significantly alter the rate of wound healing. Infection has been defined as the deposition and multiplication of organisms in tissue with an associ ated host reaction (Dealy 56). In the given case, infection is rather evident in the patient's ulcer. The presence of unhealthy granulation, thick, bloody, and malodorous exudates indicate the presence of infection. Wound infection is a problem because, at the most fundamental level, infection stops a wound from healing by prolonging the inflammatory phase, disrupting the normal clotting mechanisms and promoting disordered leukocyte function and ultimately preventing the development of new blood vessels and formation of granulation tissue. Chronic diseases like diabetes mellitus, rheumatoid arthritis, and lupus can delay the process of healing. The patient has been diagnosed with rheumatoid arthritis of 10 years duration and this has markedly affected wound healing in her case. She also has secondary hypertension and iron deficiency anemia. The presence of chronic diseases weakens the immune system, dampening its ability to counteract the pathogens attacking the
