Table of Contents HIV Test
HIV is the abbreviation for the human immunodeficiency virus, which causes the acquired immunodeficiency syndrome
HIV symptoms which may present in acute HIV infection: These are nonspecific symptoms and can present with other infections; consequently, they are unreliable indicators of HIV infection.
Remember, there is no HIV cure.
HIV window period is the time from HIV infection until a HIV Test can detect any change. Within the HIV window period, the HIV Test would be negative. During this period, the HIV viral load is extremely high, thus making the person highly infectious.
References HIV ELISA (Enzyme-linked immunosorbent assay) test generations:
- 4 weeks after exposure, a negative 4th generation HIV ELISA Test "is very reassuring / highly likely to exclude HIV infection."
- 12 weeks after exposure, a negative 3rd generation HIV ELISA Test "would definitively exclude HIV infection."
References HIV rapid test (20 minutes to results) Two types are available:
- 1st generation: HIV-1 IgG antibody
- 2nd generation: HIV-1 & HIV-2 IgG antibodies
- 3rd generation: HIV-1 & HIV-2 IgG & IgM antibodies
- 4th generation: HIV-1 & HIV-2 IgG & IgM antibodies and HIV p24 antigen
Note: If the clinic attendance is only for the HIV rapid test, then consultation fees are not added.

Individuals are eligible for HIV PEP Treatment if all the following criteria are met:
Prompt antiviral therapy may reduce the risk of HIV transmission by as much as 80%.
- less than 72 hours has elapsed since exposure;
- the exposed individual is not known to be HIV infected;
- the person who is the source of exposure is HIV infected or has unknown HIV status;
- mucous membrane or non-intact skin was exposed to a potentially infectious body fluid;
For optimal efficacy, antiretroviral therapy should be started as soon as possible, ideally within 1 hour of exposure. So that you can remain HIV negative.
The medications and dosages are the same as those used for lifelong treatment of HIV patients. However, for HIV PEP treatment, it is taken for only a month.

Cannabinoids: Now and in the Future (FR431)
Sun, 25 Jan 2015 13:03:35 +0100 | Journal of Pain and Symptom Management
Cannabinoids target orphan receptors GPR-55 and GPR-18, ion channels, monoamine receptors, and mu receptors. Cannabinoids have labeled indications for chemotherapy-induced nausea and vomiting but are reported to improve appetite in patients with AIDS, central pain from multiple sclerosis, and neuropathic pain. The benefits of cannabinoids for cancer pain are mixed. Commercially available cannabinoids are subject to psychotomimetic and addiction (cannabinomimetic) adverse effects largely through activation of the cannabinoid 1 receptor (CB1r).

Feasibility of Recruiting Peer Educators to Promote HIV Testing Using Facebook Among Men Who have Sex with Men in Peru
Sun, 25 Jan 2015 00:00:00 +0100 | AIDS and Behavior
The objective was to explore the feasibility of recruiting and training leaders to deliver a peer intervention via Facebook to promote HIV testing. Training consisted of three sessions focused on HIV epidemiology, consequences of stigma associated with HIV, and ways to use Facebook. We performed pre- and post-training evaluations to assess HIV knowledge and comfort using Facebook. We trained 34 peer leaders. At baseline, the majority of peer leaders were already qualified and knowledgeable about HIV prevention and use of social media. We found a significant increase in proportion of peer leaders who were comfortable using social media to discuss about sexual partners and about STIs. It is feasible to recruit peer leaders who are qualified to conduct a social media based HIV prevention inte...
