PTSD sources analysis - Essay Example Some people overcome this problem over time while others continue to be affected in their lifetime. Veterans especially Army and firefighters are the majority group likely to get PTSD. It has been found that people involved in combat situations are highly likely to have mental health problems due to what they encounter. After surviving in combat zones, many veterans have been seeking help in mental health care to overcome PTSD. However, they receive little or no medical attention for their life after they leave the army.4 Some of the problems that soldiers are forced to live with include anxiety, stress, and nightmares while others take their life after failing to get the necessary attention to PTSD. Because of this reason, the Veteran Affairs, set aside 300 million dollars for veteran mental health, but not all this amount will be spent.5 In fact, The Government Accountability Office (GAO) issued a report that faults the â€Å"Department of Veterans’ Affairs for failing to fully spend a promised $300 million since 2005 to fill gaps in mental illness treatment for veterans and returning troops.†6 The lack of support system in places of mental health care is due to lack of qualified medical professionals and resources.7 Moreover, there is lack of qualified mental health professionals in the field of mental health specializing in the recognition and treatment of PTSD. For example, many troops and veterans have not been screened for neurological and psychological injuries due to lack of physicians and inadequate medical screening process.8 A report published in Jan 2009 by the organization IAVA (Iraq and Afghanistan Veterans of America) states â€Å"Instead of screening troops through a face to face interview with a qualified mental health professionals, the DOD relies on an ineffective system of paper work to conduct mental health evaluations.†9 The report also mentions, â€Å"Mental health support for troops in Iraq is actually declining;

Tissue engineering - Essay Example ed to traditional methods as it solves twin problems of donor scarcity and the risks of tissue transplant rejection including transmission of diseases (Gomes & Reis, 2004, p. 738). Tissue engineering is a relatively new field of research and there is a paucity of certain academic scientific materials and research studies. It is expected this new field will have a big impact on the provision of health care in the coming years when more complex bio-materials are needed for functional tissues like bones, cartilage or large bone segments (ibid.) and even complex organs. Stem cell research has been very useful so far but there are so many ethical and other moral issues involved which has stymied large-scale efforts in this direction. Tissue engineering has no such ethical considerations as it does not involve embryonic stem cells. This new process holds much promise from the medical and economic standpoints as it skirts moral issues while potentially offering much lower costs to the patients. As example, the world market for bone grafts shows 50% are from autologous grafts while only 10% are from synthetic bio-materials thereby indicating substantial room for growth in terms of unmet market need. This entirely different approach intends to help diseased, defective or lost tissues to regenerate themselves or develop biologically-acceptable substitutes using homogeneous or heterogeneous cells. The new technique is alternatively called as regenerative medicine or as re-constructive medicine using either autogeneic cells or foreign cells. In the course of conducting research, medical scientists accidentally found out statins are very helpful in the formation of bone tissues. This coincidental or accidental discovery is very much reminiscent of the way Viagra (sildenafil citrate) was discovered to be helpful in curing ED while in the course of conducting research for finding a cure of many heart-related ailments like pulmonary arterial hypertension, angina pectoris and
