Our immune system reaction to a serious infection, trauma and stress can actually cause or worsen certain, according to the

July 4. While the new report does not refer specifically to HIV, it is possible that chronic >> << immune system in response to the virus may increase risk of depression and. When the body is stressed due to infection or injury, he produced dozens of chemical agents called cytokines. Some cytokines signal the brain and endocrine system, which can down us, encouraging us are tired and want rest. Although this causes the body to focus its energy on healing process of wounds, it can also cause or worsen symptoms of depression.

It has been described in people receiving treatment for hepatitis C virus (HCV) and some cancers, half of them experiencing depression as a side effect of immunostimulating treatment with interferon-alpha. In connection with this discovery, scientists found that people who are depressed but otherwise healthy, have elevated levels of many immune cytokines. Scientists began to study how chronic inflammation and stimulation of the immune system from diseases such as hepatitis, arthritis and HIV may actually cause or exacerbate depressive mood. In 2006, research conducted by pharmaceutical company Amgen found that people who were hyperactive immune buy generic lasix system of skin condition, psoriasis was better mood when they were cytokines firms blocker Enbrel (etanertsept). Although researchers are increasingly interested in the potential for the treatment of depression by controlling the immune system, they go with caution << Reports article. >> Many of cytokines related to depression, such as tumor necrosis factor, interferon-alpha and interferon-beta is essential for mounting an effective immune response to infection and cancer. Thus, simply blocking or reducing their number can be dangerous. Scientists are actively exploring ways in which cytokines interact with brain chemicals and hormones, however, hoping to find a safe way to blunt the mood effects of immune inflammation.

They do not accumulate and bone biopsy ...

Estrogen, calcitonin, and raloxifene are also anti-resorption drugs. They do not accumulate in bone biopsy and bone formation similar to premenopausal levels. Estrogen has been shown to lasix side effects continuously maintain strong bones for 30 years - is the only drug with such a long track record. Estrogen also has been shown to prevent fractures, including hip fractures, a large randomized trial. However, if the combination of hormones (estrogen and progestin) in women starting with ten or more years after menopause, there is an increased risk of cardiovascular disease and breast cancer. In women over 60 who started on estrogen only (without progestin) had no increased risk of cardiovascular disease and breast cancer, but there were more attacks. These risks were not observed in women who were within ten years of menopause. I think it is still advisable to use estrogen in perimenopausal women with bone density at the bottom of 10 to 15% of the population because they have low risk of baseline heart disease or breast cancer and high risk of fractures life.

After 5 to 10 years may be better to switch to another drug, such as raloksifen to minimize the risk of breast cancer that can occur with prolonged estrogen. .

In fact, your entire skeleton is replaced for about 7 years.

Here you will find a brief overview of osteoporosis - its diagnosis and treatment - as well as suggestions about where you can ask for additional information and support specialists. You can also learn more about common risk factors for osteoporosis and steps you can take to reduce risk. What is osteoporosis? Osteoporosis is a progressive condition that affects the bones, as you get older. This makes bones brittle and more prone to easily break the bones of the wrist, hip and spine are particularly susceptible. Why is this happening? Bone is living tissue with new bone replacing old bones throughout life. In fact, your entire skeleton is replaced for about 7 years. By your mid-20s, your bones in them strong. In your mid 30's, they gradually begin to become more weak and fragile because of normal age bone loss - special cells in the bones that build new bone can not run as fast as the cells that break old bones. Loss of bone mass is more rapid in women lasix 6 mg for several years after menopause and can lead to osteoporosis and increased fracture risk.

The stronger your bones when you reach 30 years, the more time is needed for bone loss leading to osteoporosis. .

But at 1 and 6 months, there were no differences ...

After the feasibility study shows that minimally invasive procedure for treatment of severe emphysema can alleviate symptoms, the researchers hoped a large randomized controlled trial would confirm that this approach was effective. But hope turned to disappointment, because

from the International Court, published today in the

The Lancet, showed that the procedure does not provide a sustainable advantage. Emphysema the drug lasix is a chronic and progressive disease that mainly the result of prolonged exposure to air irritants such as tobacco smoke and air pollution. In the tissues that support the form and function of the lungs are destroyed, patients have difficulty forcing air from their lungs that hinders breathing. There are several options for treatment and no cure for emphysema, which affects about 6000000 people worldwide. The study, which involved 315 patients with emphysema who were treated in 38 centers specializing in lung diseases, the researchers used a bronchoscope to gain access to the airway and perform airway bypass procedure in 208 patients. This procedure includes the creation of 14 small passages between the damaged tissue of the lungs and airways to release trapped air and insert stents to 6 small new ways to keep open. Such intervention, the researchers hoped that considerably reduce the amount of air remaining in lungs after full exhalation, helping to relieve breathlessness. The remaining 107 study participants received a sham procedure in which the bronchoscope was inserted, but the passages were made and no stents were placed. The next day after the procedure, improve breathing for study patients who underwent airway bypass, they have less air bubbles to the lungs and were able to inhale and exhale more deeply in comparison with those procedures deception. But at 1 and 6 months, there were no differences in symptoms between the 2 groups. Researchers have suggested that life again opened the passages of the lungs may have played a role in the disappointing results, noting that not all passes received stents and some stents were blocked with mucus. .
