The graphical results displayed an exponential decay as the mosquito ratio to human ratio was decreased compared to the peak infection number. In both the sample and New York City simulations the rate of change was much greater between the 2:1 to 1:1 ratios than from 5:1 to 4:1. This evidence suggests that as more mosquitoes are killed off, the viral peak infection number decreases exponentially. Graph 1 displays the information from table 2. The X-axis represents the number of mosquitoes removed while the Y-axis shows the peak infections.

First, the peak is significantly lower (represented by the gray line) as stated earlier with a 2:1 ratio. This suggests that the virus is not as devastating to the human population at its most intense point in the simulation. Second, the peak infection number comes much later in the 2:1 simulation. It actually takes longer for the peak infection to occur as more mosquitoes are removed. With a 5:1 ratio the peak comes at day 66 while the 2:1 ratio shows its peak at day 100. The combination of these two observations and the difference in R0 values evidences that as one kills off more mosquitoes the viral period lasts longer but less intense in the long run. The possibility of a sustained epidemic is decreased as vector control officials lower the mosquito to human ratio. In effect, the prolonged viral period has a much lower chance of successfully infecting more people. By the end of the 2:1 simulation there were seven times more people who were uninfected compared to the 5:1 simulation. Graphs 5 and 6 in the appendix show the simulation for the sample populations. The results are similar with a prolonged infectious period but a lower intensity. In the sample simulation with a 5:1 ratio the peak infection was day 50 compared to the 2:1 ratio’s peak infection of day

Chickenpox

...disease derived from chicken peas or the idea that the disease originated from chickens. Occurring in all parts of the world. Chickenpox was thought to be a form of smallpox until the late 19th century and was connected to shingles in 1888. The peak incidence is during months of March through May. Patients’ immune system does not completely clear out the virus from the body after being exposed. Chickenpox is spread from person to person. Airborne particles (sneezing and coughing), fluid from blisters, and droplets in exhaled air. Average incubation period from viral exposure to onset of symptoms is 12-14 days and symptoms can appear 10-21 days after exposed to the virus. Symptoms are rash that turns itchy, fluid filled blisters turn into scabs. Rash first on face, chest, and back. The rash then spreads to inside mouth, eyelids, and genital area. Chickenpox is rarely fatal however more severe to men than women or children. Infants, persons with weak immune systems, and pregnant women have a greater chance of contracting the virus. The also stand a greater chance of developing more serious complications that include skin infection, bone infections, joint infections, pneumonia, inflammation or infection of the brain, blood stream infections, and toxic shock syndrome. Acyclovir medications are recommended for people who are likely to develop serious diseases. Acyclovir is effective if administered within 24 hours of the first rash. Chickenpox can be diagnosed by examination of fluid...

...PREGESTATIONAL CONDITIONS CARDIAC CONDITIONS INCIDENCE: 1% or 1 in every 100 pregnancies. Over 75% of heart disease in pregnancy is valvular, often Rheumatic Fever or RHD. Effects of pregnancy on heart disease: Increased blood volume and cardiac output Cardiac output and blood volume increase about 50% more during pregnancy (increase workload to the heart) During labor and delivery, cardiac workload increases even more (every time the uterus contracts about 1 or 2 units of blood are autotransfused from utero-placental to maternal circulation. When contraction stops, this volume returns to uteroplacental and the heart may not be able to compensate with such rapid shifting. After delivery, the uteroplacental blood returns to maternal circulation increasing once again blood volume. A woman who receives epidural or spinal anesthesia, her blood vessels dilate and blood pressure decreases that results to decreased venous return which prompts the heart to compensate to meet body’s needs by pumping harder Excessive blood loss during second stage of labor. Systemic vascular resistance drops by 25% during pregnancy lowering blood pressure. Gravid uterus can dramatically affect venous return in some positions compressing IVC and can lead to hypotension.

Quality Management

...1. What does the acronym SMART signify for measurement? Why are these characteristics important? As mentioned in the textbook, good data and good measurement system are the basis for the effective quality control as well as for quality improvement. Thus, a good measure is relatively important to quality management. The acronym SMART represents simple, measurable, actionable, related (to customer and optional requirements), and timely. A good measurement should be: 1. cost effective and easy to obtain, 2. have a clear and unambiguous definition of measured objective, 3. clearly related to what is important to both external and internal customer, 4. taken at critical points in a process where value-adding activities occur to provide actionable information for making good decisions, and 5. made available and communicated to workers and managers when they need measurements. Without those characteristics, a measurement can also provide the needed information to the users, but extra cost and time will be charged. Users might not make relative good decision compare with those users with good measurements. 2. List and explain the four major categories of quality costs. Give examples of each. Quality cost can be divided into four major categories as follows: * Prevention costs: investments made to keep nonconforming products from occurring and reaching the customer. Prevention costs could be the salaries of individuals associated with quality planning...

...examples include airway inflammation, mucous plugging, narrowed airway lumina, or airway destruction. The term COPD includes chronic bronchitis and emphysema. Although asthma also involves airway inflammation and periodic narrowing of the airway lumina (hyperreactivity), the condition is the result of individual response to a wide variety of stimuli/triggers and is therefore episodic in nature with fluctuations/exacerbations of symptoms. Asthma: Also known as chronic reactive airway disease, asthma is characterized by reversible inflammation and constriction of bronchial smooth muscle, hypersecretion of mucus, and edema. Precipitating factors include allergens, emotional upheaval, cold weather, exercise, chemicals, medications, and viral infections. Chronic bronchitis: Widespread inflammation of airways with narrowing or blocking of airways, increased production of mucoid sputum, and marked cyanosis. Emphysema: Most severe form of COPD, characterized by recurrent inflammation that damages and eventually destroys alveolar walls to create large blebs or bullae (air spaces) and collapsed bronchioles on expiration (air-trapping). ------------------------------------------------- Diagnostic Studies * Chest x-ray: May reveal hyperinflation of lungs, flattened diaphragm, increased retrosternal air space, decreased vascular markings/bullae (emphysema), increased bronchovascular markings (bronchitis), normal findings during periods of remission (asthma). * Pulmonary function tests: Done...

Epidemiology

...Epidemiology Paper Anavictoria Fortaleza March 5, 2012 NUR408 Epidemiology Paper Vulnerable populations are "those with a greater than average risk of developing health problems by virtue of their marginalized socio-cultural status, their limited access to economic resources, or personal characteristics such as age and gender" (De Chesnay & Anderson, 2008). Infants and young children are vulnerable to a host of healthcare problems, they are susceptible to viral infection especially respiratory infection such as Respiratory Syncytial Virus. In this paper, the author will define and describe epidemiological triangle as it relates to respiratory syncytial virus (RSV), types of epidemiology, and levels of prevention of RSV. Epidemiology Definition Epidemiology is defined as "the study of the distribution and determinants of health-related states or events in specified populations, and the application of this study to control of health problems" (Stanhope & Lancaster, 2008). The study of epidemiology is important because it search for causes or factors that are related with increased risk or likelihood of disease, it deals with group of people rather than with individual person, and it helps public health with decision making and aids in developing and evaluating interventions to control and prevent health problems (CDC, 2012). Epidemiology is used to "monitor the health of various populations, understand the determinants of health and disease in communities, and...

It seems that no one is really sure what cause diabetes. They do say that a virus infect the body. When the virus infect the body the person immune system starts to produce antibodies and that fight the infection. The cells that are in charge of making the antibodies are called the T – Cells. The T- Cells also fight the virus. There is also a cell call the beta cells. Beta Cells make the insulin in the pancreas. If the virus has some of the same antigens as the beta cells, it may take a long time (several years) for the T- Cells to damage most of the beta cells. In type 1 diabetes the original viral infection is what refection to set off the development. Every virus...

Azithromycin as an Acne Medication

...resulting appearance may lead to anxiety, reduced self-esteem, and in extreme cases, depression or thoughts of suicide. Acne develops as a result of blockages in the skin's follicles. These blockages are thought to occur as a result of the following four abnormal processes: a higher than normal amount of sebum production (influenced by androgens), excessive keratin deposition leading to comedone (blackheads) formation, colonization of the follicle by Propionibacterium acnes bacteria, and the local release of pro-inflammatory chemicals in the skin. Azithromycin is an antibiotic. Antibiotics work by suppressing the growth of bacteria that contribute to acne symptoms. Overall, Azithromycin is rated as a mediocre treatment for acne. Users report that, Azithromycin is somewhat effective for improving acne symptoms and that this medication tends to have mild side effects. Although there is a lot of research supporting the use of azithromycin to treat acne, it is not commonly used for this purpose. Numerous studies have shown that azithromycin can produce a significant improvement of acne symptoms for some patients. The major limitation of the use of azithromycin to treat acne are the increasing levels of azithromycin resistant bacteria. The research data about the antibiotic susceptibility of Propionibacterium acnes bacteria indicates that resistance to all of the macrolide family antibiotics (especially azithromycin, erythromycin and clarithromycin)  is becoming more common. Recent...

...Influenza Introduction Influenza is among the most prevalent infectious airborne viral diseases that affect the respiratory system. According to the World Health Organization (2016), the infection majorly affects the throat, nose, and the bronchi, and on rare occasions, it may affect the lungs. Also commonly known as the flu, influenza infection is characterized by sneezing, itchy and running nose as well as throat inflammation. The initial signs and symptoms include fever with temperatures higher that 100F, soreness in the back, myalgia, legs and arm muscles, sweats and chills, frontal or retro-orbital headaches, tachycardia, red, watery eyes, and fatigue. Sometimes, a dry and persistent cough, nasal congestion and discharge occur (Clark & Lynch, 2011). Causes and Transmission The Influenza viruses are transmitted in the form of droplets through the atmosphere whenever an infected individual speaks, coughs or even sneezes. A healthy person can either get infected through directly inhaling these contaminated droplets or obtain the viruses from contaminated objects like computer keyboards, mouses or even the phones, and move them to the respiratory pathways like the nose and mouth. According to Clark & Lynch (2011), the infected individuals become contagious a day before the appearance of the first symptoms and continue in this state up to 5 to 10 days after. Studies have revealed that young children and individuals with compromised immune systems remain in the contagious...

Coccioidiodal Mycosis

...et al., fungal infections are classified into categories based on anatomic location and epidemiology. The most frequent anatomic categories are mucocutaneous and deep organ infections. The most common epidemiologic categories are endemic and opportunistic. The endemic mycoses, such as coccidioidomycosis, are infections caused by fungal organisms that are not found in normal human flora and are instead acquired from environmental sources. In contrast, organisms found in normal human microbial flora cause opportunistic infections. Endemic fungal infections are acquired almost exclusively by inhalation of molds in the environment. Soil, dust, and dirt are the natural reservoirs for most of these infections, demonstrated by an increase in cases following dust storms, seismic events, archeological digging, or recreational activities (Fauci et al., 2008). The incidence of endemic fungal infections has risen substantially over the past several decades, especially in geographic locations in which there has been substantial population growth (Fauci et al., 2008). Healthcare providers may be required to recognize and treat an increasing number of severe coccidioidal infections as growth and urbanization to these areas increases. Additionally, a recent study of community-acquired pneumonia (CAP) in Arizona suggested coccidioidomycosis might be a common cause.  Patients with CAP and endemic exposure should receive laboratory evaluation for coccidioidal infection.  Because of...
