Stem Cell Treatment for Spinal Cord Injury – Beike …

Posted: Published on April 17th, 2018

Acupuncture Acupuncture is a technique in which practitioners stimulate specific points on the body - most often by inserting thin needles through the skin. It is one of the most effective practices used in traditional Chinese medicine. Acupuncture stimulates nerve fibers to transmit signals to the spinal cord and brain, activating the bodys central nervous system. The spinal cord and brain then release hormones responsible for making us feel less pain while improving overall health. Acupuncture may also: increase blood circulation and body temperature, affect white blood cell activity (responsible for our immune function), reduce cholesterol and triglyceride levels, and regulate blood sugar levels. Aquatherapy Aquatic Physical Therapy is the practice of physical therapy in a specifically designed water pool with a therapist. The unique properties of the aquatic environment enhance interventions for patients with neurological or musculoskeletal conditions.

Hormone Replacement Therapy – Ideal Physician Weight Loss

Posted: Published on April 16th, 2018

Hormone Replacement Therapy For Weight Loss There is a definite case to be made for the role of hormones in weight management. When our hormones are out of balance, we can experience weight gain and sluggishness that leads to less exercise. This reduction in our physical activity can compound the problem by resulting in more weight gain. Luckily, this is a fight you may be able to win by simply changing a few bad habits. Ultimately, learning how to balance your hormones can help you lose weight. First Stop: Stress Many people find that, when under stress, they eat more. While this propensity to over indulge could be the result of an emotional issue, it is more often a result of the hormone Cortisol. Cortisol is released by your body when you have the need for adrenaline; this is often referred to as, fight or flight. If you were in a physically dangerous position and needed extra energy to fight someone or flee from something, the release of some of your stored glucose as a result of Cortisol would give you the energy to punch or run. After a release of Cortisol, you find yourself hungry and exhausted. In todays … Continue reading →

Guidelines for Standards in Cardiac Surgery

Posted: Published on April 16th, 2018

The following statement is an updated version of guidelines that were first published by the American College of Surgeons in 1991. The revised statement was developed by the Advisory Council for Cardiothoracic Surgery and approved by the College's Board of Regents in October 1996. This report provides guidelines to be used by hospital executives and appropriate medical staff only. It places no value judgment on existing successful programs or on the treatment of individual patients. While current standards of practice form the basis of this report, it is recognized that large programs in cardiac surgery grow from smaller ones. Hospitals and their staffs should exercise their own discretion in approving programs based on local need and the responsibility for achieving a good standard of practice. While attention is directed primarily to open-heart surgery, the proposed standards should apply to closed-heart operations as well as to operations on the great vessels within the chest. In borderline situations, in which the number of open-heart operations does not meet the established guidelines, the American College of Surgeons recommends the use of peer review. Specification of the qualifications for cardiac surgeons in an established practice is beyond the scope of these guidelines. Surgeons practicing … Continue reading →
