That figure grew to almost 11 percent in 2008, according to the Scientific Registry of Transplant Recipients. That increase has provoked ethical concerns about the interpretation of "irreversible" since "patients may still be alive five or even 10 minutes after cardiac arrest because, theoretically, their hearts could be restarted, [and thus are] clearly not dead because their condition was reversible." Gender inequality
The majority of organ donors are women. For example, in the United States, 62% of kidney donors and 53% of liver donors are women. In India, women constitute 74% of kidney donors and 60.5% of liver donors. Additionally, the number of female organ recipients is conspicuously lower than that of male recipients. In the U.S., 35% of liver recipients and 39% of kidney recipients are women. In India, the figures are 24% and 19% respectively. Political issues
There are also controversial issues regarding how organs are allocated to recipients. For example, some believe that livers should not be given to alcoholics in danger of reversion, while others view alcoholism as a medical condition like diabetes. Faith in the medical system is important to the success of organ donation. Brazil switched to an opt-out system and ultimately had to withdraw it because it further alienated patients who already distrusted the countrys medical system. Adequate funding, strong political will to see transplant outcomes improve, and the existence of specialized training, care and facilities also increase donation rates.
As of 2009 there were globally approximately 958,000 annual cases and 625,000 deaths within three months after infection.Although C. neoformans infection most commonly occurs as an opportunistic infection in immunocompromised people (such as those living with AIDS), C. gattii often infects immunocompetent people as well.Cryptococcus (both C. neoformans and C. gattii) is the dominant and leading etiologic agent of meningitis in adults with HIV and is considered an "emerging" disease in healthy adults. Though the rate of infection is clearly higher with immunocompromised individuals, some studies suggest a higher mortality rate in patients with non-HIV cryptococcal meningitis secondary to the role of T-cell mediated reaction and injury. CD4+ T cells have proven roles in the defense against Cryptococcus, but it can also contribute to clinical deterioration due its inflammatory response. Diagnosis
Dependent on the infectious syndrome, symptoms include fever, fatigue, dry cough, headache, blurred vision, and confusion. Symptom onset is often subacute, progressively worsened over several weeks. The two most common presentations are meningitis (an infection in and around the brain) and pulmonary (lung) infection.Any person who is found to have cryptococcosis at a site outside of the central nervous system (e.g., pulmonary cryptococcosis), a lumbar puncture is indicated to evaluate the cerebrospinal fluid (CSF) for evidence of cryptococcal meningitis, even if they do not have signs or symptoms of CNS disease. Detection of cryptococcal antigen (capsular material) by culture of CSF, sputum and urine provides definitive diagnosis. Blood cultures may be positive in heavy infections.
