In the last 20 years, there has been a dramatic upsurge in the average weight of Australian adults. In this period, on average, Australian women have gained 4.8 kg, whilst Australian men have gained 3.6 kg. Consequently, the prevalence of obesity in men has increased from 8% to 19% and in women from 7% to 21%. This threatens to wipe away many recent health gains, as obesity has been associated with a wide range of chronic and debilitating illnesses, such as diabetes, heart disease, some cancers, sleep apnoea and osteoarthritis. Any weight gain in adulthood is usually as a result of an increase in fat stores, and the risk of ill-health from increasing weight actually begins at quite low BMI. Unfortunately, weight gain can be difficult or slow to reverse in the middle years because of physiological and behavioural changes that occur at this time of life. Adults should focus on preventing or minimizing weight gain over time by retaining physical activity within their daily living and by sensible dietary changes. Even if weight gain does occur with age, a regimen of regular exercise and a diet rich in fruit and vegetables and low in fat will provide some protection against a rapid decline in health.

Arthritis is a growing health concern in the US with approximately 70 million Americans currently affected. This figure will inevitably rise as the population ages. The pain and decreased mobility associated with arthritis have a significant impact on quality of life and because patients with arthritis are less active than the general population, they are at risk of additional conditions such as obesity, heart disease, diabetes, and hypertension. There are currently no disease modifying osteoarthritis (OA) drugs available; therefore anti-inflammatory, and/or analgesic medications such as acetaminophen and NSAIDs and simple analgesics form the mainstay of treatment. Coxibs may be preferred to traditional NSAIDs because of their improved gastrointestinal (GI ) safety and tolerability profile. The use of topical agents may also be beneficial in some patients. In rheumatoid arthritis (RA) where disease modifying drugs (DMARDs) are available, anti-inflammatory agents such as NSAIDs and coxibs are used as adjuncts to disease modifying therapy. However, patients with RA are at increased risk of NSAID-related GI injury, particularly if they are also on corticosteroid medication. Pharmacological treatment of both RA and OA should be combined with appropriate nonpharmacological modalities such as patient education, exercise programs, and joint motion and strengthening exercises. Such activities may delay joint degradation and help maintain physical function.

To understand the potential role of cyclooxygenase (COX) in normal and inflammatory human diseases, we characterized the expression of COX-1 and COX-2 in biopsies of osteoarthritis, atherosclerosis, and cancer. Tissues were prepared for immunohistochemistry by standard methods, and representative cases assayed via Western blot and quantitative RT-PCR. COX-2 was not detected in normal human tissues with few exceptions. Moderate to marked COX-2 was observed in the macula densa (MD) and thick ascending limb (TAL) in human fetal kidneys, but was not detected in neonatal and adult MD and TALs. Low level, constitutive COX-2 was detected in colonic epithelium, peribronchial glands, and pancreatic ductal epithelium. Low to moderate COX-2 was detected basally in the cortex, hippocampus, hypothalamus, and spinal cord, and in reproductive tissues during ovulation, implantation and labor. No COX-2 was detected in the existing vasculature in normal tissues, and was also not expressed throughout the ductus arteriosus. COX-2 was markedly induced in human tissues of osteoarthritis, atherosclerosis and cancer. COX-2 was prominently expressed in the synovium, fibrocartilage of osteophytes, and in the blood vessels in the osteoarthritic (OA) knee joint. COX-2 was also prominently detected in the macrophages/foam cells in atherosclerotic plaques, and in the endothelium overlying and immediately adjacent to the fibrofatty lesion. Moderate- to intense COX-2 expression was consistently observed in the inflammatory cells, neoplastic lesions, and blood vessels in all epithelial-derived human cancers studied. In contrast, COX-1 was relatively ubiquitously observed in both normal and pathophysiological conditions. These data collectively imply COX-2 plays an important role in mediating a variety of inflammatory diseases, and imply COX-2 inhibitors may be effective in the prevention and/or treatment of OA, heart disease, and epithelial cancers.

Obesity is a chronic disease in the same sense as hypertension and atherosclerosis. The cause of obesity is an imbalance between the energy ingested in food and the energy expended. The excess energy is stored in fat cells that enlarge or increase in number. This hyperplasia and hypertrophy of fat cells is the pathologic lesion of obesity. Enlarged fat cells produce the clinical problems that are associated with obesity, either because of the weight or mass of the extra fat or because of the increased secretion of free fatty acids and numerous peptides from enlarged fat cells. The consequence of these two mechanisms is other diseases, such as diabetes mellitus, gallbladder disease, osteoarthritis, heart disease, and some forms of cancer.

Posttraumatic stress disorder (PTSD) is associated with high rates of medical service use and with self-reported poor health. Male veterans admitted to a rehabilitation unit for PTSD (N=55) or alcohol dependence (N=38) were evaluated for comorbid psychiatric and medical conditions and health risk factors. Patients with PTSD were more likely to have osteoarthritis, diabetes, heart disease, comorbid depression, obesity, and elevated lipid levels. These findings suggest that there may be a relationship between specific medical conditions, possibly mediated by behavioral risk factors, among the aging population of veterans with PTSD.

Obesity is a chronic disease caused by an imbalance between the energy ingested in food and the energy expended. Enlarged fat cells produce the clinical problems associated with obesity either because of the weight or mass of the extra fat or because of the increased secretion of free fatty acids and numerous peptides from enlarged fat cells. The consequence of these two mechanisms is other diseases, such as diabetes mellitus, gallbladder disease, osteoarthritis, heart disease, and some forms of cancer. The spectrum of medical, social, and psychologic disabilities includes a range of medical and behavioral problems.

Studies have shown that about 30 per cent of people who have chronic obstructive pulmonary disease (COPD) lose weight. Weight loss has been shown to be associated with a reduction in lung function (Poole, 1993). Conversely, patients who are overweight have an increased respiratory workload due to their extra weight. Excess weight also increases the risk of hypertension, diabetes, heart disease and osteoarthritis (Collins, 2003). Many patients are unaware of changes in their nutritional status. The case study in Box 1 provides an illustration of this.

Obesity is an epidemic disease that threatens to inundate health care resources by increasing the incidence of diabetes, heart disease, hypertension, and cancer. These effects of obesity result from two factors: the increased mass of adipose tissue and the increased secretion of pathogenetic products from enlarged fat cells. This concept of the pathogenesis of obesity as a disease allows an easy division of disadvantages of obesity into those produced by the mass of fat and those produced by the metabolic effects of fat cells. In the former category are the social disabilities resulting from the stigma associated with obesity, sleep apnea that results in part from increased parapharyngeal fat deposits, and osteoarthritis resulting from the wear and tear on joints from carrying an increased mass of fat. The second category includes the metabolic factors associated with distant effects of products released from enlarged fat cells. The insulin-resistant state that is so common in obesity probably reflects the effects of increased release of fatty acids from fat cells that are then stored in the liver or muscle. When the secretory capacity of the pancreas is overwhelmed by battling insulin resistance, diabetes develops. The strong association of increased fat, especially visceral fat, with diabetes makes this consequence particularly ominous for health care costs. The release of cytokines, particularly IL-6, from the fat cell may stimulate the proinflammatory state that characterizes obesity. The increased secretion of prothrombin activator inhibitor-1 from fat cells may play a role in the procoagulant state of obesity and, along with changes in endothelial function, may be responsible for the increased risk of cardiovascular disease and hypertension. For cancer, the production of estrogens by the enlarged stromal mass plays a role in the risk for breast cancer. Increased cytokine release may play a role in other forms of proliferative growth. The combined effect of these pathogenetic consequences of increased fat stores is an increased risk of shortened life expectancy.

With an increased prevalence of obesity in developed countries, associated chronic diseases rise in a parallel way. Morbidity secondary to overweight and obesity include type 2 diabetes, dislipemia, hypertension, heart disease, cerebrovascular disease, cholelithiasis, osteoarthritis, heart insufficiency, sleep apnoea, menstrual changes, sterility and psychological alterations. There is also a greater susceptibility to suffer some types of cancer, infections, greater risk of bacteremia and a prolonged time of wound healing after surgical operations. All these factors indicate that obesity exerts negative effects upon the immune system. Immune changes found in obesity and their possible interrelations are described in this article. Changes produced during obesity affect both humoral and cellular immunity. It is known that adipose tissue, together with its role as energy reserve in form of triglycerides, has important endocrine functions, producing several hormones and other signal molecules. Immune response can be deeply affected by obesity, playing leptin an important role. Properties of leptin, alterations of leptin levels in different situations and its changes with different medical and surgical therapies for obesity are described in this article.

Devil's claw is the common name for two species in the genus Harpagophytum. Their root extracts contain the iridoid glycoside, harpagoside, which has been found to be effective in the treatment of degenerative rheumatoid arthritis, osteoarthritis, tendonitis, kidney inflammation, and heart disease. Most of the world's supply comes from Namibia, with lesser amounts from South Africa and Botswana. In 2002, the peak year of export, 1018 tonnes of dried tubers were exported from southern Africa, representing the harvest of millions of plants. In 2001, sales in Germany were estimated at 30 M euros, accounting for 74% of the prescriptions for rheumatism. Harvest has improved income levels in marginalized communities but it has also raised questions of sustainability. In 2000, recommendations were made to the Convention on the International Trade in Endangered Species (CITES) to add devil's claw to Appendix II. In 2004, the proposal was formally withdrawn due to the efforts of the range states to address sustainability issues. Replacing wild collection with cultivation has generated a debate on the positive and negative effects on harvester income and rural farmers. Successful cultivation efforts have involved micropropagation techniques and growing the plant without water or fertilizers. The governments of the main range states are working with local communities to develop policies and regulations to protect the species and to determine a sustainable harvest.
