The worst of the 20th century influenza pandemics was the 1918 outbreak, which epidemiologists estimate was responsible for the deaths of between 40-100 million people worldwide, making it one of the most deadly events in human history. In studies of human populations, a lethal synergism has been identified between influenza virus and pneumococcus, a likely cause of excess mortality from secondary bacterial pneumonia during influenza epidemics. 6 percent in 1980 to 9 percent in 2005. Within a month of this nadir, the number of lymphocytes tends to return to normal levels. Alternately, measles virus infection may stimulate the production of cells that are directly responsible for suppressing HIV replication. Intentional weight loss is the loss of total body mass as a result of efforts to improve fitness and health, or to change appearance through slimming. As a result of the floral changes produced by global warming, a significant escalation is occurring in global rates of allergies and asthma. In principle, this is possible if medical treatment or medical research is involved in creating conditions that increase the likelihood that two or more diseases come together in a population. Many victims died within 48 hours of the appearance of the first symptom. Eating restrictions may also be imposed as part of treatment or investigations. S. Notably, investigators in the study reported a higher risk of HIV infection was found among participants who had an existing immunity to the common cold virus (known as adenovirus type 5 or Ad5). The vaccine was created using a mixture of three components, each of which was made in the laboratory with a replication-defective version of Ad5. In part, the death toll during the pandemic was caused by viral pneumonia characterized by extensive bleeding in the lungs resulting in suffocation. In the study, children who had measles, and reported various typical symptoms, including fever, rash, conjunctivitis, runny nose, and cough, had a significant drop in HIV levels detectable in the blood as compared to HIV-infected children who were not infected with measles. Inability to eat can result from: diminished consciousness or confusion, or physical problems affecting the arm or hands, swallowing or chewing. Compounding the problem of air quality is the fact that air-borne pollens have been found to attach themselves to diesel particles from truck or other vehicular exhaust floating in the air, resulting in heightened rates of asthma in areas where busy roads bisect densely populated areas, most notably in poorer inner city areas. Another type of syndemic relationship involves one disease enhancing the virulence of another. In other cases, syndemic interaction among diseases is apparent but the pathways of linkage are not yet clear. This appears to be the case, for example, with syphilis and HIV coinfection as a result of genital-tract ulceration caused by the former supporting sexual transmission of the latter. Increases in rates of asthma have occurred despite improvements in air quality produced by the passage and enforcement of clean air legislation, such as both the Clean Air Act of 1963 and the Clean Air Act of 1990 in the United States. Multiplication of these pathogens may be inhibited by bodily defenses unless these are weakened by a herpesvirus infection of the periodontium. Asthma among children has been increasing at an even faster pace than among adults, with the percentage of children with asthma going up from 3. Similarly, there is evidence that periodontitis, which can lead to tooth loss, may arise from a syndemic. Discussion of deleterious disease interactions raises a question about the possibility of an opposite kind of disease interaction, namely: are there counter syndemics, disease interactions that lower the burden of disease in a population below the sum effects of the individual diseases involved. The death toll of the 1957 pandemic is estimated to have been around two million globally, with approximately 70,000 deaths in the United States. 75%). Contact between Native Americans and Europeans led to syndemics among the Native American population due to diseases introduced during the Columbian Exchange. Several potential mechanisms could be responsible for the temporary suppression of HIV replication early in the course of a measles infection. (April 2013) ( Learn how and when to remove this template message ). Several factors are known to contribute to the onset of type 2 diabetes, including diet, obesity and aging. White hunting parties scoured the region, sometimes shooting hundreds or even thousands of bison a day. Researchers suggested one explanation for the higher rate of HIV infection among individuals in the treatment group was that the vaccine lowered defenses against the human immunodeficiency virus. Statements consisting only of original research should be removed. population according to the U. Specifically, results showed that of the 741 volunteers in the vaccine group, 24 developed HIV infection (3. In each case, mortality rates were determined primarily by five factors: the number of people who became infected, the virulence of the virus causing the pandemic, the speed of global spread, the underlying features and vulnerabilities of the most affected populations, and the effectiveness and timeliness of the prevention and treatment measures that were implemented. Both of these cancer-causing viruses are known to infect the same poultry flock, the same chicken, and, even the same anatomic cell. As a result, while the official mortality rate on the reservation was between one and two percent, the death rate was probably closer to 10 percent, a devastatingly high figure. Lack of food can result from: poverty, difficulty in shopping or cooking, and poor quality meals. The pandemic was responsible for about one million deaths around the world, almost 34,000 of which were in the United States. Changes to metabolic demands can be caused by illness, surgery and organ dysfunction. Additional syndemics are being identified around the world as public health officials, researchers, and service providers begin to focus on the connections among diseases and the social context factors that foster disease concentration and interactions. Statements consisting only of original research should be removed. Other counter-syndemics are likely to be discovered as a syndemic perspective emphazing paying attention to processes and relationships diffuses among researchers. In some syndemic interactions—such as the one between diabetes and SARS —changes in biochemistry or damage to organ systems caused by one disease (in this case, diabetes), such as weakening of the immune system, promotes the progression of another disease (SARS). Again, as seen with the previous two 20th century global influenza outbreaks, disease interaction appears to have been critical, underlining the importance of syndemics more generally in the production of major public health crises. There can also be losses from drains, including nasogastric tubes. There is evidence, for example, that herpesvirus has this effect on HIV infection, with progression to AIDS being significantly accelerated by co-infection with herpesvirus. The 1957 pandemic was caused by the Asian influenza virus (known as the H2N2 strain), a novel influenza variety to which humans had not yet developed immunities. A little over a decade later, the comparatively mild Hong Kong influenza pandemic erupted due to the spread of a virus strain (H3N2) that genetically was related to the more deadly form seen in 1957. In fact, it was not uncommon for people who appeared to be quite healthy in the morning to have died by sunset. As is so often the case with health, including health conditions directly affected by global warming, the poor and marginalized suffer the gravest consequences. Recent research findings suggest that counter-syndemics do occur and are part of the complex world of co-morbidity. Poor appetite can be a direct symptom of an illness, or an illness could make eating painful or induce nausea. There were three influenza pandemics during the 20th century that caused widespread illness, mortality, social disruption, and significant economic losses. Thus, two (or more) diseases can be comorbid but no interaction occurs between them, while in other cases interaction occurs but it has beneficial rather than deleterious consequences. S. population, but the rate of affected individuals has been steadily climbing in recent years, especially in low income, ethnic minority neighborhoods in cities. Asthma, characterized by episodic inflammation and narrowing of small airway passages in the lungs, affects about 8 percent of the U. Centers for Disease Control and Prevention. The asthma prevalence among American Indians, Alaska Natives and black people is 25 percent higher than white people. Fungal illnesses, endocarditis, many parasitic diseases, AIDS, and some other subacute or occult infections may cause weight loss. The food that was provided to the Sioux was insufficient and of low quality. Several different kinds of interaction among diseases have been described, including both indirect (changes caused by one disease that facilitate another through an intermediary) and direct interface (diseases act in direct tandem). Among ethnic minority populations, Puerto Ricans the rate of asthma is 125 percent higher than non-Hispanic white people and 80 percent higher than non-Hispanic black people.
The pandemic had devastating effects as disease spread along trade and shipping routes and other corridors of human movement until it had circled the globe. Moreover, as was typical of treaties with Native peoples, the government reneged on its promises. Cancer, a very common and sometimes fatal cause of unexplained ( idiopathic ) weight loss. This was the organism selected to serve as a carrier, or delivery vector, for three synthetically produced HIV genes. Intentional weight loss is commonly referred to as slimming. Other losses: Conditions such as burns can be associated with losses such as skin exudates. This can result from conditions that affect the digestive system. As knowledge about diseases has advanced, it is increasingly realized that diseases are not independent and that synergistic disease interactions are of considerable importance for prognosis. The term syndemic is further reserved to label the consequential interactions between concurrent or sequential diseases in a population and in relation to the social conditions that cluster the diseases within the population. Already it is known that risk for serious infections of various kinds increase significantly with poor diabetes control, but appreciation of more complex relationships between infection and type 2 diabetes is now emerging as well. The role of infection, however, is only beginning to be understood. In some cases, coinfection may open up multiple syndemic pathways. For example, William Moss and fellow researchers at the Johns Hopkins Bloomberg School of Public Health have found that human immunodeficiency virus is transiently suppressed during an acute measles infection. There is a significant level of evidence indicating that the influenza virus alters the lungs in ways that increase the adherence, invasion and induction of disease by pneumococcus. Alternately, one disease can assist the physical transmission of another disease. 2%), while among the 762 volunteers in the placebo arm of the trial, 21 developed HIV (2. All of these, in turn, are shaped, to greater or somewhat lesser degree, by overarching political economic structures globally and locally. Patients who have uremia often have poor or absent appetite, vomiting and nausea. By the early 1880s, the last of the great herds of bison upon which Plains Indian peoples like the Sioux were dependent as a food source were gone, victims of economic greed as well as a conscious plan to control Plains Indian populations. In coinfected cells, the retroviral DNA of the avian leukosis virus can integrate into the MDV genome, producing altered biological properties compared to those of the parental MDV. Syndemic theory seeks to draw attention to and provide a framework for the analysis of adverse disease interactions, including their causes and consequences for human life and well-being. An example is the apparent interaction that occurs between type 2 diabetes mellitus and hepatitis C viral infection. About one-third of unintentional weight loss cases are secondary to malignancy. Currently, allergic diseases constitute the sixth leading cause of chronic illness in the United States, impacting the lives of 17 percent of the population. Similarly, in gum infection, periodontal bacteria may enhance the virulence of herpesvirus. This singular approach proved useful historically in focusing medical attention on the immediate causes and biological expressions of disease and contributed, as a result, to the emergence of targeted modern biomedical treatments for specific diseases, many of which have been successful. S. The Sioux found themselves confined on a series of small reservations where they were treated as a conquered people. Cancers to suspect in patients with unexplained weight loss include gastrointestinal, prostate, hepatobilary ( hepatocellular carcinoma, pancreatic cancer ), ovarian, hematologic or lung malignancies. In places like India, the mortality rate reached 50 per 1,000 population. There is a possibility that this precise event occurred, for example, during a randomized, double-blind clinical trial testing the efficacy of the prototype HIV vaccine called V520. The traditional biomedical approach to disease is characterized by an effort to diagnostically isolate, study, and treat diseases as if they were distinct entities that existed in nature separate from other diseases and independent of the social contexts in which they are found. HIV suppression also has been identified in patients suffering tsutsugamushi disease, a mite-borne infection found in Asia and Australia, also known as scrub typhus, although the how this occurs is not clear. Moreover, it has been argued that countless numbers of those who expired quickly from the disease were co-infected with tuberculosis, which would explain the notable plummet in TB cases after 1918 (because so many carriers of the disease perished during the influenza pandemic). Epidemics, in short, including their emergence, course, and impact (and whether they become widespread pandemics that exact a sorrowful toll on life and well-being) are sculpted by the configuration of human social relationships including prevailing patterns of social inequality. In other words, novel organisms created through splicing of genes from two naturally occurring pathogens may have increased the rate of disease. A syndemic is the aggregation of two or more diseases in a population in which there is some level of positive biological interaction that exacerbates the negative health effects of any or all of the diseases. The discovery of counter-syndemics is important because such entities may suggest novel strategies for the prevention and treatment of disease. Please improve it by verifying the claims made and adding inline citations. The low point in lymphocyte levels occurs just prior to the onset of the distinct red circular skin rash (called rubeola) characteristic of a measles infection. Losses from the gastrointestinal can occur because of symptoms such as vomiting or diarrhea, as well as fistulae and stomas. Please improve it by verifying the claims made and adding inline citations. Interest in the syndemics perspective has been driven by growing evidence of the regularity of interactions among diseases and recognition that this interaction influences disease course, expression, severity, transmission, and diffusion. Thus, in 1980 asthma was found to affect only about three percent of the U. Treaties that were signed with the Sioux in 1868 and 1876 stipulated that they would be provided with government annuities and provisions in payment for sections of their land and with the expectation among federal representatives that the Sioux would become farmers on individually held plots of land. S. g. Given that social conditions can contribute to the clustering, form and progression of disease at the individual and population level, there is growing interest in the health sciences on syndemics. Weight loss issues related to specific diseases include. While other explanations of the results exist, the study suggests the possibility of the emergence of syndemics with an iatrogenic origin. Disease cooccurrence, with or without interactions, is known as comorbidity, coinfection, and associated terms. Periodontitis is known to be caused by bacteria of several different species (e. This finding was the product of a study of HIV-infected children living in Zambia. frontier. Weight loss occurs when the body is expending more energy in work and metabolism than it is absorbing from food or other nutrients. Additionally, Moss and co-workers found that median plasma levels of RANTES, a chemokine that attracts immune system components like eosinophils (a kind of white blood cell that destroys parasitic organisms), monocytes (a precursor of macrophages), and lymphocytes, were higher in HIV-infected children with measles than in those without measles. It is estimated that in 1860 there were well over 10 million bison living on the American Plains. An example of this scenario would be the use of gene splicing to unite two pathogenic agents and introducing the resulting novel organism into a population. Cardiovascular disease, especially congestive heart failure, may cause unexplained weight loss. (April 2013) ( Learn how and when to remove this template message ). An example of a syndemic from the 19th century can be found on the reservations on which Native Americans were confined with the closing of the U. In other words, existing legislation and regulation have not kept pace with changing climatic conditions and their health consequences. , Porphyromonas gingivalis, Dialister pneumosintes, Prevotella intermedia ) that adhere to and reproduce on tooth surfaces, especially under the gum line. Among those who survived the first several days, however, many died of secondary bacterial pneumonia.
