INTRODUCTION Asthma is a chronic medical condition affecting a significant portion of the United States population. Inflammation is present in the bronchus and bronchioles, whose primary goal is to delivery oxygen to the lungs. Due to this inflammation, a cough, wheeze, and shortness of breath develop as the lungs struggle to maintain proper oxygen levels. Symptoms of asthma can come and go making asthma diagnosis difficult, therefore; it is important to be aware of triggers that may cause symptoms for individuals.2 A thorough preliminary study was conducted using informational data from the Behavioral Risk Factor Surveillance System (BRFSS) and the Asthma Call-back Survey (ACBS) from 2006 to 2008.3 It was noted that asthma prevalence continued to increase in the United States population dating back to the 1980s; however, data relating to asthma incidence was typically omitted due to deficiency of the data collected.3 The purpose of their study was to discover current asthma prevalence and incidence rates, as well as determine if the known demographic patterns of asthma prevalence coincided with the patterns of asthma incidence.3 The BRFSS was a random-digit-dialed telephone survey reaching out to one member in each household located in the 50 US states (as well as neighboring districts) allowing an adult to also act as a proxy for any one child in each household.3 Researchers were able to determine asthma prevalence by conducting two interview questions of "Have you ever
R.J. is a 15-year-old boy with a history of asthma diagnosed at age 8. His asthma episodes are triggered by exposure to cats and various plant pollens. He has been using his albuterol inhaler 10 to 12 times per day over the last 3 days and is continuing to wheeze. He normally needs his inhaler only occasionally (2 or 3 times per week). He takes no other medications and has no other known medical conditions. Physical examination reveals moderate respiratory distress with a respiratory rate of 32, oximetry 90%, peak expiratory flow rate (PEFR) 60% of predicted, and expiratory wheezing.
Throughout the years knowledge about asthma has grown, as well as treating it effectively. Over 300 million people are said to be victims of this disease with another 100 million being estimated by 2025 globally (Currie and Baker, 2012). In the United Kingdom, asthma is increasingly becoming one of the leading disease affecting individual of different age, ethnicity, race and gender. British Lung Foundation (2011) stated that it is more common at childhood stage and can also occur at a later age. According to Asthma UK (2014) asthma in men is less prevalence than it is in women and children troubled more with asthma than adults. Recent data in the UK shows that in children and occupational asthma in adult is on the rise with an estimate
Asthma is a chronic inflammatory disorder of the bronchial mucosa and hyperreactive bronchial tubes. Its etiology has been linked to both genetic and environmental factors. Several genes, including those that influence the production of proteins and cells involved in the immune response (such as interleukins, eosinophils, mast cells) have been linked with asthma. A decreased number of T-regulatory cells is also associated with asthma. Environmental factors linked with asthma include exposure to allergens, urban residence, and smoking (or exposure to secondary smoke). Recurrent respiratory tract viral infections may also contribute to the development of asthma. Decreased exposure to certain infectious organisms during early childhood, and the consequent underdevelopment of the immune response, can also lead to the development of asthma--this is known as the hygiene hypothesis (McCance & Huether, 2014, p. 1263-4).
This results in Hispanics Americans living in very tightly-knit segregated urban communities, in older housing, and lack access to healthcare that can contribute to asthma exacerbation (Bhan et al., 2015). In the State of Connecticut there is a program called, Putting on AIRS or Asthma Indoor Risk Strategies. This program designed to assess environmental risk in the homes for asthmatic children and families. The hope is to reduce the frequency of asthma-related events by identifying environmental triggers. A public health nurse experienced in asthma management, conducts asthma education in the home. There is also an assessment for environmental asthma triggers in the home such as roach infestation or mold. The program follows participants over a six-month time frame, and has been shown to significantly improve outcomes for asthmatics (Nepaul et al.,
As of 2009, studies conducted by the CDC have shown that asthma impacts approximately one in every twelve people, and the numbers only continue to grow (CDC, 2011). Some of the most common symptoms can range anywhere from coughing (especially at night or during exercise), wheezing and chest tightness, to shortness of breath. Asthma is often a chronic condition and while many times it can present itself as being mild, it can also sometimes lead to death if a person suffers an asthma attack. Asthma can be genetic, but it can also be caused, as well as exacerbated by, environmental factors such as air pollution. Studies have shown that children living in the Bronx are experiencing asthma at levels eight times higher than the national average. In addition, rates of death from asthma are a whopping three times higher than the national average, and hospitalization rates at about five times higher.” (Ruppell, 2000). Asthma is not a disease that targets only one group of people, yet the Bronx still exhibits disproportionately high levels of asthma especially in neighborhoods that are poorer areas of the city. In fact, people from these poor areas are 21 times more likely to be hospitalized due to asthmatic conditions compared to people from more affluent parts of the city (Ruppell,
Since asthma exacerbations in adolescence can lead to emergency room visits, hospitalizations, missed school and diminished health status, there was an evident need for effective asthma management for this population (Quaranta et al., 2014). Unfortunately, these rural adolescents with asthma, and their families, had difficulty determining when their asthma was poorly controlled; and unless the asthma symptoms were disruptive to family life, there was often little motivation for these individuals to seek medical care, thus increasing the risk of poor outcomes (Quaranta et al., 2014, p. 99). According
Asthma is prevalent in all countries regardless of level of the development. According to the World Health Organization 235 million people worldwide have asthma. It is however estimated that 80% of asthma deaths occur in low income countries (World Health Organization, 2015). Within the United States there are many climates and environmental triggers that can cause an exacerbation is asthma symptoms. According to the NHLBI hospitalization is three times higher among African Americans than white, and Puerto Ricans have the highest rate of asthma attacks and deaths related to asthma. Severe asthma is more common among women, children, low income inner city residents, Puerto Ricans, and African American. This disparity within the
Asthma is a chronic inflammatory disease of the airway that impacts a person’s and their family’s quality of life. In people with asthma, their airway becomes constricted with swelling and excessive mucous. This constriction or narrowing of the airway makes it difficult for the person with asthma to breath (Massachusetts Department of Public Health, 2009). If asthma is left uncontrolled, it leads to further wheezing, coughing, shortness of breath, tiredness, and stress. (Massachusetts Department of Public Health, 2009).
In order to reset EPA air-quality standards and to determine which therapeutic actions can be applied to patients to prevent deterioration of their asthma conditions (Neukirch et al., 1998), researchers have found it increasingly necessary to discover the relationships between asthma symptoms and episodes of air pollution and to identify the pollutants that are responsible for the rise in the number of people seeking respiratory medical treatment.
Asthma can be defined as a chronic pulmonary disease that involves inflammation and bronchospasms. To fully understand asthma and its attributes, one must understand the pathophysiology of asthma, including the lower respiratory tract, and the bronchiolar smooth muscle.
To better understand the impact of asthma, a brief overview of the causes (aetiology) and disease progression (pathophysiology) must be shown. As common as asthma is, not much is known about its aetiology, according to findings presented by Subbaroa, Mandhane and Sears (2009, pg. 181-187) in a review from the Canadian
Asthma is a chronic breathing condition that has no cure. However, the good news is that patients can live a normal life with the right treatment. Below is a list of treatments that are available for asthma:
Breathing is a vital process for every human. Normal breathing is practically effortless for most people, but those with asthma face a great challenge. During an asthma attack, breathing is hampered, making it difficult or even impossible for air to flow through the lungs. Asthma is an increasingly common problem, and has become the most common chronic childhood disease. At least 17 million Americans suffer from it(1), and although it can be fatal, it is usually not that severe(4). There is no cure for asthma, but with proper care, it can usually be controlled.
Asthma is a chronic lung disease characterized by episodes in which the bronchioles constrict due to oversensitivity. In asthma, the airways (bronchioles) constrict making it difficult to get air in or out of the lungs. Breathlessness is the main symptom. The bronchi and bronchioles become inflamed and constricted. Asthmatics usually react to triggers. Triggers are substances and situations that would not normally trouble an asthma free person. Asthma is either extrinsic or intrinsic. Extrinsic is when the inflammation in the airway is a result of hypersensitivity reactions associated with allergy (food or pollen). Intrinsic asthma is linked to hyper responsive reactions to other forms of
Asthma is a chronic airway disease that can be difficult to manage, resulting in poor outcomes and high costs (Kuhn et al., 2015). It is characterized by episodes of expiratory airflow obstruction, which occurs in response to multiple stimuli or triggers. Asthma is a lifelong disease, and symptoms include wheezing, breathlessness, chest tightness, and coughing. Attacks can be mild, moderate, severe, or even life threatening and limit a person’s way of life (Centers for Disease Control and Prevention (CDC), 2011). There is no known cure for asthma, but symptoms can be controlled by avoiding the triggers and taking prescribed medicines that prevent or minimize symptoms.
