Hiv And Its Effects On Children - 1149 Words

HIV What is HIV? HIV stands for human immunodeficiency virus. Infection by this virus frequently leads to AIDS – acquired immunodeficiency syndrome. Viral infection initially causes a flu-like illness characterized by fever, sore throat, headache, rash, gastrointestinal discomfort, and body aches (mylagias). The virus tends to stay dormant for months or years while it is slowly killing immune cells – especially CD4 cells. Individuals with high viral loads and low CD4 cell counts have high viral infectivity and tend to develop opportunistic infections – atypical infections that generally affect immunocompromised hosts.

Patients eventually develop opportunistic infections as their CD4 counts decrease below 200. How common is HIV infection? HIV is relatively common in the United States and responsible for a fair amount of deaths. This condition is a frequent cause for referral to an infectious disease specialist. In 2015, worldwide - approximately 37 million adults and children had HIV or AIDS, 2 million were newly infected that year, and 1 million people died of the condition. Sub-Saharan Africa makes up about 75% of the word’s HIV-infected population. Approximately 3.3 million children have HIV/AIDS in the world – most of these patients are born in sub-Saharan Africa and Southeast Asia. The prevalence of HIV seems to be stabilizing overall, however some countries are still demonstrating an increase. Since 2001, there has been about a 38% decrease in the incidence of HIV infection. What are the symptoms and signs of HIV infection? Symptoms of acute HIV infection are flu-like and typically include: †¢ Fever †¢ Enlarged and painful lymph nodes - lymphadenopathy †¢ Rash †¢ Sore throat †¢ Body aches †¢ Headache †¢ Weight loss †¢ Night sweats †¢ Anorexia - loss of appetite These typically subside and the virus then hibernates in the lymphatic system.

Overpopulation Is An Environmental Issue - 1816 Words

The question does not concern whether or not overpopulation is an environmental issue. The evidence is clear, the majority of researchers address this established issue with their own reasoning behind what the biggest cause or effect is. Overall, Hardaway (2014) found that around every one third of a second, the world creates room for one more human. Creating room for another person requires 3.2 tons of carbon, 2,000 square meters of fresh water, and 207 gigajoules of energy (Hardaway, 2014). This takes up more room and resources that the earth does not have. With this rapid growth in population, by the year 2050, the earth would need to have another living area the size of Brazil to accommodate for all the people (Kuo, 2012). With the lack of land availability, overpopulation will be impossible to survive off current natural resources. Researchers focus on why and how overpopulation is effecting the earth such as pollution, consumption, lack of resources, and overcrowding (Ku o, 2012; Wutich and Brewis, 2014). Overpopulation has numerous effects on the environment, and there are many different views on what is causing the biggest effect on the earth. Description Some researchers believe that pollution is the biggest effect on the earth. Pollution is one of the most well-known results of overpopulation.

Discussion Question on country competitiveness Free Essays

Country competitiveness Is determined by a multitude of factors that ‘measures and compares the effectiveness of countries In providing firms with an environment that sustains the domestic and International competitiveness of those firms’ (Sheehan Lou: Chi. 5, p. 130). We will write a custom essay sample on Discussion Question on country competitiveness or any similar topic only for you Order Now How a countries excel In bringing firms to contribute to the country competitiveness is the result of many factor that are evaluated yearly by the Forum in order to rank almost every country. The report is called Global Competitiveness Index, although it offers over 500 pages; the content is laid out in an orderly fashion and easy to follow. Let’s have a look at how these factors/ determinants influence over FAD strategy. Country-Level, Industry-Level, Firm-Level, Individual-Level Factor-driven economies (Institutions, Infrastructure, Macroeconomic environment, Health and primary education) The level of competitiveness contributing to the country success can be well due to Its Institutional competitiveness; the competitive advantages that firms create In result of their operation wealth a specific circle of institutions is the driving capability to succeed in a socioeconomic context. Foreign firms will likely invest more where they know there is a good management of legal, lattice and economic institutions to protect their rights and property. Mature infrastructures facilitate connectivity, thus lessening the distance between territories. Strong network infrastructures interconnected with national market encourage economic development. Transport, communication and telecommunication infrastructure system is what allow entrepreneurs to do their business, quick stream of information increases global economic productivity by allowing businesses to interact and make decisions. Macroeconomic factor alone, even though stable does not Increase the country’s competitiveness but a macroeconomic disorder can actively affect the economy. Workers need to be able to rely on good health services to avoid unnecessary absenteeism. Good health has proven to enable workers to better function. Also, workers who are educated increase their efficiencies at work but are limited to more manual jobs than one where a more elaborate process is involved. Thus, a lack of basic education can also limit the growth off firm’s capacity to develop. (Sheehan Lou, up. 139) Mentioned that countries cannot be competitive on every level. Some of the week area can be mitigated through trade agreement. Paraguay is a known to experience frequent power shortages at peek hour. That may cause a MEN to choose to locate in another country if their productions demand usage of electricity. Efficiency-driven economies (Higher education and training, Goods market efficiency, Labor market efficiency, Financial market development, Technological readiness, Market size) Well-educated and continuous training is fundamental to firm who want attractive for a firm that evolves in the market technology and is always on a learning path to react and adapt to the fast pace IT progresses. To be better positioned in the racket, government with a well balanced set of market rules that does not restrict business productivity, but instead encourages foreign MEN to locate in the country. Per instance, restringing rules and heavy administrative paperwork causes delay that can result in missing out opportunities. In finance, there are always uncertainties, but putting all these factors together can provide a fair level of competitiveness. Not mentioned here though is the impediment of the financial economy when dealing with tax rate, interest rate, deficit and public debt in general also depend on how government manages its public accounts. An example would be a decrease in the FAD inflow in the U. S last year compared to the previous ones. Many factors that caused this decreased percentage of foreign investment are explained by Jackson,J. K. (2013) in a report prepared for committee member of Congress. Innovation-driven (Business sophistication, Innovation) In order to succeed in that factor, support from private and public sector is essential. For example, program subvention in R D is often what create a breakthrough in many sectors. Developing countries don’t often have the knowledge and the people like scientist to run that program.

The Left-Sided Heart Failure

Question: Discuss about The Left-Sided Heart Failure. Answers: Concept map on chronic left-sided heart failure The pathogenesis of acute exacerbation of chronic heart failure of the left side is accompanied by reduced cardiac output transferred to the circulatory system and affects the pulmonary system of the body. The heart functions by pumping from lungs the oxygenated blood and push the blood into the left atrium. The blood then moves into the left ventricle and finally gets distributed throughout the whole body (Fung, 2013). The left ventricle is usually larger than the other chambers of the heart and it provides the power to pump the blood providing the normal functioning of the organ. The normal functioning of the left ventricle is disrupted the heart fails to provide required amount of blood into the entire system of the body. The left-sided heart failure forces the heart to pump the blood harder to accomplish the amount. The two mechanisms responsible for the left-sided heart failure are: i) dysfunction and ii) systolic dysfunction of the heart. In case of the failure of the diastolic function of the heart, the left ventricle becomes stiffer and thicker, inhibiting the filling of the lower part of the left chamber sufficiently (Guazzi, Cahalin Arena, 2013). This reduces the amount of blood to be pumped out. In the later stage, the blood starts to from congestion in the left ventricle further proceeding to the lungs causing abnormal sounds called the crackles which was reported in the clinical examination of Mrs. Brown. In case of systolic dysfunction, the heart is restricted to pump out the blood into the circulatory system (Lilly, 2012). The clinical manifestation of left-sided heart failure with severe dyspnoea, development of bilateral cackle sound in the lungs, increased blood pressure are related to chronic exacerbation of the failure of heart that was diagnosed in Mrs. Brown aged 78 years old. The pressure gets elevated in the left atrium and pulmonary system due to uncertain increase in the blood of left ventricle. The normal drainage in alveoli of the lungs are affected which also effects the normal mechanism of the gaseous exchange (West, 2012). All these reasons lead to dyspnoea disorder. The atrial fibrillation reported in Mrs. Brown is caused by faster beating of the heart in order to compensate the pumping power that is lost (Katz Konstam, 2012). The increased rate of pulses in the patient is due to this reason. The increased in blood pressure disrupts the normal flow of the blood and causes elevated high pressure clinically reported in the patient of concern. As the heart is unable to pump out the requi red blood, the blood returns back to venous system taken via lungs. The blood accumulating inside the alveoli of the lungs produces crackles sound with auscultation (Boucher et al., 2013). Mrs. Brown showed a fall SpO2 level with 85%, whereas the normal saturation level of oxygen remains between 95-99% (Radak et al., 2013). As in case of the heart failure, the adequate blood is not pumped out affecting the lungs; low oxygen is transported by the blood in the body, which is determined by the oxygen saturation level. All these are the clinical symptoms with respect to exacerbation of left-sided heart failure (Corsonello et al., 2013). The nursing strategies are formulated diagnose acute left-sided heart failure. Among the various interventions, the two most potential nursing strategies for controlling the cardiac output are discussed here in treating Mrs. Brown. i) Controlling the Cardiac output: Regular readings of the heart rate with apical pulses and showing any kind of irregularity in heart rate should be noted (Fung, 2013). The rationality of this strategy is that in order to compensate the reduced contraction of the ventricle, the heart rate increases termed as tachycardia. The palpation of peripheral pulse can be helpful to determine the decreased cardiac output. Regular monitoring of the blood pressure is vital that occurs with increased vascular resistance (Mancia et al., 2013). Whenever body cannot overcome, hypotension occurs. Apart from all these, change in skin colour and cyanosis inspection should be done. Reduced peripheral perfusion causes a pale appearance due to abnormal cardiac output. Appearance of cyanosis can reflect heart failure. ii) Supplying ventilation and oxygenation: Proper auscultation of the sound produced during breathing and recording any kind of crackles is required to record any kind of pulmonary congestion and accumulated secretions (Boucher et al., 2013). In order to lower the oxygen demand and improvise the inflated lung the patient should be given complete bed rest and lifting the bed on the head side at 30degree angle with proper support. Oxygenation prescribed by the doctor in charge can be reduces the hypoxemia (Radak et al., 2013). Mrs. Brown was given IV furosemide and sublingual glyceryl trinitrate. Furosemide is a loop diuretic that restricts the water reabsorption in nephrone. This drug inhibits the action of co-transporter of sodium, potassium and chloride in the Henles loop. Furosemide also reduces the venous pressure by reducing the intravascular volume, the pulmonary veins pressure and pressure created in filling the chambers of the heart (Costanzon Jessup, 2012). The capacity of the venous system increases and the circulation becomes normal. The other drug named glyceryl trinitrate reduces the resistance of the pulmonary vascular system and dilates the venous and arterial system (Lozo et al., 2014). This vasodilator causes activation of the guanylate cyclase that activates the protein kinase pathway phosphorylating the cells of smooth muscle giving rise to dephosphorylation of the myosin chain. In the later stage, the release of the calcium ions cause vasodilation and relaxes the smooth muscle cells. The side effects of furosemide are impairment in hearing, itching, pain progression from upper stomach to back, feeling of nausea with vomiting and urine becomes darker (Costanzon Jessup, 2012). The side effects of glyceryl trinitrate are feeling dizzy, vomiting, decreased blood pressure, headache, and appearance of sore and itching (Lozo et al., 2014). Therefore, while giving these medicines to Mrs. Brown; utmost monitoring should be done to restrict any of these side effects. As one of the drugs was given intravenously, proper care should be taken to avoid kind of inflammation at the applied site (Goldschneider et al., 2014). Prevalence of any kind of allergies with respect to the medicines should also be monitored. The respiratory rates, blood pressure, the crackling sounds if measured normal, it can be said that the drugs have positive effect towards the patient.
