Disease major causes

Rotavirus. Rotavims causes infant diarrhea, a disease which has major socio-economic impact. In developing countries it is the major cause of death in infants worldwide, causing up to 870,000 deaths per year. In the United States, diarrhea is stiU a primary cause of physician visits and hospitalization, although the mortaUty rate is relatively low. Studies have estimated a substantial cost benefit for a vaccination program in the United States (67—69). Two membrane proteins (VP4 and VP7) of the vims have been identified as protective epitopes and most vaccine development programs are based on these two proteins as antigens. Both Hve attenuated vaccines and subunit vaccines are being developed (68). [Pg.359]

Respiratory Syncytial Virus. Respiratory syncytial vims (RSV) causes severe lower respiratory tract disease in infants. It is the major cause of hospitalization in the United States (- 90,000 events/yr) and it has a high mortaUty rate in neonates and other high risk populations, such as the geriatric population (51). Development of an RSV vaccine has always been a major priority, however, earlier attempts have mostiy failed (70). [Pg.359]

The air inside a factory building can be polluted by release of contaminants from industrial processes to the air of the workroom. This is a major cause of occupational disease. Prevention and control of such contamination are part of the practice of industrial hygiene. To prevent exposure of workers to such contamination, industrial hygienists use industrial ventilation systems that remove the contaminated air from the workroom and discharge it, either with or without treatment to remove the contaminants, to the ambient air outside the factory building. [Pg.40]

Chronic obstructive pulmonary disease (COPD) affects over 5% of the adult population, is the fourth leading cause of death worldwide and is the only major cause of mortality that is increasing worldwide. It is an inflammatory disorder of the lungs, caused mainly, but not exclusively, by cigarette smoking. 15-20% of smokers develop COPD. [Pg.362]

Cardiovascular disease affects 2.7 million British people and is a major cause of mortality with circulating neutrophils being proposed as contributing factors in ischaemic damage, though damage can still occur in vitro in the absence of blood. Melanocortins have... [Pg.754]

Globally, undernutrition is widespread, leading to impaired growth, defective immune systems, and reduced work capacity. By contrast, in developed countries, there is often excessive food consumption (especially of fat), leading to obesity and to the development of cardiovascular disease and some forms of cancer. Deficiencies of vitamin A, iron, and iodine pose major health concerns in many countries, and deficiencies of other vitamins and minerals are a major cause of iU health. In developed countries, nutrient deficiency is rare, though there are vulnerable sections of the population at risk. Intakes of minerals and vitamins that are adequate to prevent deficiency may be inadequate to promote optimum health and longevity. [Pg.474]

Carotid artery disease is one of the major causes of ischemic stroke. The predominant mechanisms by which it causes stroke are (a) arterial embolism from atherosclerotic plaques (b) hemodynamic changes, leading to watershed infarcts and (c) distal propagation of thrombus originating from acute carotid occlusion. ... [Pg.205]

Ischemic heart disease (IHD) is also called coronary heart disease (CHD) or coronary artery disease. The term ischemic refers to a decreased supply of oxygenated blood, in this case to the heart muscle. Ischemic heart disease is caused by the narrowing of one or more of the major coronary arteries that supply blood to the heart, most commonly by atherosclerotic plaques. Atherosclerotic plaques may impede coronary blood flow to the extent that cardiac tissue distal to the site of the coronary artery narrowing is deprived of sufficient oxygen in the face of increased oxygen demand. Ischemic heart disease results from... [Pg.64]

Solid-organ transplant recipients are at increased risk of infectious diseases, which is a major cause of early morbidity and mortality. The prevalence of posttransplant infection depends... [Pg.845]

Factors that can predispose patients to developing metabolic bone disease include deficiencies of phosphorus, calcium, and vitamin D vitamin D and/or aluminum toxicity amino acids and hypertonic dextrose infusions chronic metabolic acidosis corticosteroid therapy and lack of mobility.35,39 Calcium deficiency (due to decreased intake or increased urinary excretion) is one of the major causes of metabolic bone disease in patients receiving PN. Provide adequate calcium and phosphate with PN to improve bone mineralization and help to prevent metabolic bone disease. Administration of amino acids and chronic metabolic acidosis also appear to play an important role. Provide adequate amounts of acetate in PN admixtures to maintain acid-base balance. [Pg.1507]

The results were that income inequality was strongly associated with lack of social trust, and that states with high levels of social mistrust had higher age-adjusted rates of total mortality (level of social trust explained 18% of variance in total mortality, under their regression). Lower levels of social trust were associated with higher rates of most major causes of death, including coronary heart disease, malignant neoplasms, cerebrovascular disease, unintentional injury, and infant mortality. [Pg.77]

In the past several decades there has been increased incidence of depression, which motivated Gerald Klerman to describe this era as the age of melancholia [5], The lifetime prevalence of depression in the U.S. is higher in women (21.3%) than in men (12.7%). Although the rates of major depression vary across the world, data from fifty countries support the notion that this disease is the fourth leading cause of disability worldwide (second in developed countries) [3]. Longitudinal studies verify that the typical course of the disease is recurrent, with periods of recovery and periods of depression symptoms however, approximately 17% of patients have a chronic unremitting disease [6], Depression is the major cause of suicidal behavior and the rate of suicidal attempts has been estimated to be around 56% in depressed patients [7]. [Pg.380]

A broad variety of diseases may cause neuropathic pain. The majority of diseases associated with neuropathic pain involve the peripheral nervous system. These diseases include traumatic injuries hereditary, metabolic, inflammatory or paraneoplastic neuropathies and infections. However, neuropathic pain can also be caused by injuries or disorders affecting the spinal cord or the brain (central neuropathic pain) tumors stroke epilepsy and neurodegenerative disorders [20]. Genetic factors appear to contribute to inter-individual differences in the susceptibility to neuropathic pain. [Pg.935]

Chagas disease is caused by a kinetoplastid trypanosoma parasite and affects millions of people in Latin America. The disease is currently incurable. Chemotherapy is based mainly on nitrofuran and nitroimidazole compounds and sterol biosynthesis inhibitors such as ketoconazole (337). Toxicity and high doses are the major problems for these organic drugs. Urbina et al. (338, 339) have found that com-plexation of antiparasitic organic agents such as chloroquine (78)... [Pg.241]
