    But Dr. Lin said the emergence of antibiotic-resistant bacteria - “superbugs” such as CRE and MRSA- portend a return to the “pre-antibiotic era.” He cited a need to develop new antibiotics and to more judiciously use those now available.

Although there may be a limited role for criminal law in rare cases in which people transmit HIV with malicious intent, we prefer to see people living with HIV supported and empowered from the moment of diagnosis, so that even these rare cases may be prevented. This requires a non-punitive, non-criminal HIV prevention approach centred within communities, where expertise about, and understanding of, HIV issues is best found.

    45 Words You Should Know: HIV/AIDS

    If you or a loved one has been recently diagnosed with HIV, you undoubtedly have a lot of questions about what the condition means for you and your future.

    One of the challenges of an HIV diagnosis is navigating through a whole new set of acronyms, slang, and terminology. Don’t worry: we’re here to help. Hover over the 45 most commonly used terms and lingo to see what they mean, and get a better understanding on the condition.

  • The Big Benefits of Doing HIV Tests Yourself, at Home - Facts So Romantic
    http://nautil.us/blog/the-big-benefits-of-doing-hiv-tests-yourself-at-home

    The next time you stop at the local drug store to pick up household standbys like shampoo, ibuprofen, and tissues, , you might also consider picking up something rather more serious: an HIV test. Show your ID (the test is only approved for adults aged 17+), pay $40, and you can return home and learn your HIV status in as little as 20 minutes. You won’t even have to prick your finger. And because these OraQuick HIV home test kits are carried by Walmart and several other major pharmacies, there is a very good chance that you could have the test in your hand within 15 minutes. It works a little like a pregnancy test. The kit comes with a swab, instructions for use, and phone numbers for help or counseling in case the results bring distress. OraQuick finds HIV by tagging antibodies in (...)

    2013 will be remembered as an exceptional year in shaping our strategy to control HIV/AIDS. Indeed, a few weeks after the 30th anniversary of the discovery of the virus, a decisive step was made in deciding how to use antiretroviral therapy (ART) for treatment and prevention worldwide. New WHO public health guidelines recommended that ART should be started in all adults who reach a threshold of 500 CD4 cells per μL.1 These guidelines were based on a strict review process and on the grounds of clinical and epidemiological benefits. Yet their application at country level remains challenging and operational guidance is needed now the target population has expanded to almost 30 million people living with HIV.2

    A growing number of Greek residents have injected themselves with HIV so they can claim about $950 in monthly health benefits, according to a report commissioned by the World Health Organisation.

    The report, Review of social determinants and the health divide in the WHO European Region, found cases of self-inflicted HIV infections in Greece, as the population continues to grapple with a deeply troubled economy.

    The country’s suicide rate has also skyrocketed, while healthcare access has declined.

  • Sex, lies and economics: Researcher’s map of infidelity wins Polanyi Prize - The Globe and Mail

    In economist Roland Pongou’s native Cameroon, one in 20 people are infected with HIV/AIDS, and women more so than men. When probing the gender disparity, he reached a curious conclusion: Women are less likely to cheat on their partners and, oddly, that makes them more vulnerable.

    Dr. Pongou’s research into networks of infidelity has won him the prestigious Polanyi Prize, one of five $20,000 awards to be handed out Monday to early-career researchers in Ontario, named in honour of John Polanyi, who won the Nobel Prize for chemistry in 1986.

  • Why fish farming can help people living with HIV in Liberia | Afua Hirsch | Global development | theguardian.com
    http://www.theguardian.com/global-development/2013/sep/17/fish-farming-help-liberia-hiv-positive

    Good nutrition is particularly important for people with HIV. Research has shown they need much higher than average levels of protein (pdf) to prevent their health from deteriorating and to allow healthy growth. “Nutrition is one of the key things if you are taking anti-retroviral drugs,” said Chon. “The drugs are toxic, and if you don’t have food to eat, they can make you very ill.”

    “But food in Liberia is very expensive. We buy expensive imported rice, even though we should be growing it ourselves, and fish is difficult for most people to afford.”

    Sheehy says Grow2Feed is the first co-operative fish farm in Liberia to operate for the benefit of an HIV-positive community. The project has attracted the interest of the Liberian government, and the UN Food and Agriculture Organisation (FAO), which has worked with Grow2Feed to provide training, will also support teaching at the University of Liberia.

  • Untangling the Web of Antiretroviral Price Reductions (16th edition) | Médecins Sans Frontières (MSF/ Doctors Without Borders)
    http://www.msf-seasia.org/14807

    Today at the International AIDS Society conference in Kuala Lumpur, Médecins Sans Frontières (MSF) launches two reports: the 16th edition of Untangling the Web of Antiretroviral Price Reductions, MSF’s report on price and access issues around antiretrovirals (ARVs), medicines used to treat HIV; and Putting HIV Treatment to the Test: A Product Guide for Viral Load and Point-of-Care CD4 Diagnostic Tools

    This year’s edition of Untangling the Web finds that although the price of first- and second-line ARVs have come down thanks to increased generic competition, third-line or salvage regimens remain exorbitantly priced, with middle-income countries such as Armenia paying more than US$13,000 per person per year for raltegravir, just one of the three or four drugs needed in a third-line cocktail. MSF also finds that while patents remain a barrier on newer drugs and in middle-income countries, some countries are using World Trade Organization-sanctioned TRIPS flexibilities to issue compulsory licences to allow more affordable access. Voluntary licences, however, are the preferred method by originator companies of selling new, patented ARVs to countries, but those companies are increasingly excluding all but least-developed and sub-Saharan African countries from their licences. Free trade agreements are also increasingly posing a threat to access to medicines in negotiating countries, with the EU-India Free Trade Agreement and the Trans-Pacific Partnership Agreement causing the most concern over proposed harmful provisions.

    MSF’s pricing analysis also extends to viral load monitoring tests in Putting HIV Treatment to the Test. Routine evaluation of a person’s viral load is important because it helps to identify who needs help in adhering to ART. Where adherence problems can be ruled out and treatment failure has already occurred (because drug resistance mutations have developed), viral load can help guide a switch to second-line treatment. Viral load can help prevent viral transmission, because non-viraemic patients (people with ‘undetectable’ viral load) have a very low risk of transmitting HIV. Viral load is a much more accurate way than the commonly used CD4 count to determine how well someone is doing on treatment, potentially an avoiding unnecessary switch to more expensive second- or third-line treatment. However, current viral load tests are expensive and complex for remote and resource-limited settings. Putting HIV Treatment to the Test looks at these issues on a number of viral load and point of care CD4 diagnostic tests.

    ...levels of premature mortality in China relative to other members of the G20 in 2010.

    For men in China in 2010, age-standardised rates of years of life lost due to ischaemic heart disease, lower respiratory infections, cirrhosis, diabetes, preterm birth complications, chronic kidney diseases, HIV/AIDS, and tuberculosis were significantly better than the G20 mean. China had significantly worse ranks than the mean for stroke, chronic obstructive pulmonary disease, liver cancer, stomach cancer, oesophageal cancer, leukaemia, drowning, and falls. The YLL rates of road injury and lung cancer for 2010 are indistinguishable from the mean but the absolute increase in YLLs from these causes is concerning. For women in China, we noted better than G20 average performance on ischaemic heart disease, lower respiratory infections, diabetes, breast cancer, preterm birth complications, chronic kidney diseases, cervical cancer, cirrhosis, and cardiovascular and circulatory diseases. We noted worse than G20 average outcomes for stroke, chronic obstructive pulmonary disease, road injury, self-harm, liver cancer, stomach cancer, oesophageal cancer, falls, drowning, and rheumatic heart disease.

    Even for conditions such as ischaemic heart disease, lung cancer, and diabetes (for which China was better than average in the G20 in 2010), rising rates suggest that this status might change in the near future.

  • Study: cannabis compound might have use as an HIV drug (Wired UK)
    http://www.wired.co.uk/news/archive/2013-05/1/cannabis-hiv-drug

    The way it works is by interaction with the cannabinoid type-2 (CB2) receptor in white blood cells, specifically the macrophages. Macrophages are one of many types of white blood cell in humans. While the main cells, the lymphocytes, do the bulk of the work in fighting infection by tracking down and destroying germs with antibodies, macrophages form a kind of backup part of the immune system — attracted to damaged cells, they surround and engulf them while also alerting lymphocytes of new dangers.

    Macrophages have an unpleasant weakness, though, in that they are one of the first types of cells to be infected by HIV when it enters the body. The virus can live inside macrophages for days, weeks or months, travelling around the body, infecting other cells and acting as an extremely effective pollinator of HIV.

    Stopping the HIV virus from infecting macrophages is one method researchers are investigating, as it would dramatically curtail the speed at which the infection progresses and would give time for other antiretrovirals to help keep it at bay, or even remove it.

    The CB2 receptor in macrophages is stimulated normally when THC enters the bloodstream, so nothing unusual there. However, it appears that macrophages that have their CB2 receptor stimulated are stronger when it comes to fighting and weakening the HIV-1 virus.

    This was discovered when the research team from the Temple University School of Medicine in Philadelphia infected macrophages with the HIV-1 virus, before then exposing cell cultures to one of three types of synthetic THC that specifically target the CB2 receptor. Comparing these cell cultures after seven days against a control group revealed a clear decrease in the rate of HIV-1 infection. Effectively, the macrophages had become stronger at keeping the HIV-1 virus out.

    ...

    An added benefit of targeting only the CB2 receptor is that its only affect is to stimulate the macrophages — the psychoactive component of THC is experienced when the CB1 receptor gets targeted. Synthetic THC compounds can be produced to only target the CB2 receptor in this way. THC has also been shown in studies not to suppress the immune systems of those who take it, meaning that the findings could provide hints at a future drug that, in combination with other methods, could be used for suppressing the HIV-1 virus.

    The study has been published in The Journal of Leukocyte Biology.

    CHICAGO (AP) — Nearly 250 Illinois physicians put their names behind a proposal Tuesday that would legalize marijuana for patients with serious illnesses, hoping to give a boost to the legislation one day before an anticipated vote on the House floor.
    Three of those doctors spoke at a press conference in Chicago, saying the drug can be a safer and more effective treatment than narcotics for patients with diseases such as cancer, Parkinson’s disease and HIV.
    (…)
    The Illinois House is expected to vote Wednesday on a bill that would create a medical marijuana pilot program. It would allow physicians who have an existing relationship with a patient to prescribe marijuana for certain conditions.

    Patients would be limited to buying 2.5 ounces [70 g] at a time from dispensaries licensed and regulated by the state. They would be prohibited from growing their own marijuana, and both patients and caregivers would have to undergo a background check.

    The vote in the House is expected to be close. If it passes the legislation still must go to the Senate.

  • Cheap drugs a bitter pill for the West | Mail & Guardian

    The Ugandan government faced an easy choice when it decided to start producing its own version of a key malaria treatment, rather than continuing to rely on expensive imports. Since the country began making its own medicine in 2007, Uganda has produced not only anti-malarials, but also antiretrovirals (ARVs) used to treat HIV. The public-private company, Quality Chemicals, plans to roll out more ARVs, anti-malarials and antibiotics in the coming months and years. 

    The venture, a shining example of African pharmaceutical manufacturing, was made possible in part because Uganda is considered a “least-developed country”. As such, it doesn’t yet have to respect international intellectual property laws (...)

    But least-developed countries may be running out of time. They have until July to adopt the agreement’s measures into their own laws and a continued extension for pharmaceutical products until 2016.

    The melittin coated nanoparticles attack HIV cells and not other cells because researchers have added “protective bumpers” on the surface of the cells. Since healthy cells are large, the nanoparticles simply bounce off the surface. However, because of its small size, HIV gets caught in the nanoparticles where it is attacked by the bee toxin.

    Researchers add that the nanoparticles are safe for the sperm as they are for vaginal cells.

    The paper seeks to explain some of the events and narratives arising pre and post #Marikana about the industry, government, mine workers, and in particular, the health rights of workers. She argues that health rights (silicosis, TB and HIV) is a missing narrative in the general response to Marikana and associated events. While most commentators have sought to explain the political, industrial relations, and economic aspects of Marikana, they have not yet focused significant attention on lung disease caused by mine work and its socio-economic consequences for workers in Southern Africa’s mining communities.

    http://groundup.org.za/content/politics-protest-cape-town

    suites du massacre de Marikana — les oppositions entre « durs » et « mous » se tendent

    For those who have begun to take civil disobedience into middle class spaces, the logic goes that it is better to be vilified and taken notice of than to be given ’lip service delivery’ from the government. In other words, the escalation of protests by poor black communities is an indication of the complete lack of democracy for anyone who can’t afford to purchase their right to a voice in the elite public sphere.

    (...) It is quite concerning, therefore, that a collection of Cape Town-based activist oriented NGOs have been making a significant effort to vilify certain forms of protest that do not fit within its directors’ and funders’ view of what constitute ’acceptable’ forms of protest.

    To be sure, many of these NGOs can claim important victories. The Treatment Action Campaign, for instance, has had a significant impact in helping turn the tide from AIDS denialism to a more proactive HIV/AIDS health policy at the national level. However, just as often, well-funded and publicised protests led by NGOs have gone nowhere, fast. Despite bringing more than 10,000 people into the streets of Cape Town last year to demand that the state build one library per school, Equal Education has not been able to compel the government to build any more libraries. Instead, the Western Cape is now closing down 27 schools in the province. Legal protests have done nothing to prevent this from happening.
    (...)

    One of the best examples of real immediate success from illegal protest tactics was the 2007 blockade of the N2 by thousands of residents of the Joe Slovo shack settlement in Langa. The community was resisting the then Housing Minister Lindiwe Sisulu’s flagship N2 Gateway housing project which was attempting to evict 20,000 Joe Slovo residents to ’temporary relocation areas’ in Delft, a bleak and underdeveloped township on the far outskirts of the city.
    (...)

    Unfortunately, many of the leaders of NGO based civil society moralistically lambaste disruptive tactics in protests here in Cape Town while hypocritically forgetting that they simultaneously support those same tactics in other struggles throughout the world. For instance, respected activist Zackie Achmat attacked Abahlali baseMjondolo’s non-violent but disruptive Informal Settlement Strike in 2010 while a year later hosting Israeli Yonatan Pollak from Anarchists Against the Wall, a respected activist who consistently engages in disruptive and sometimes violent civil disobedience protests against the Israeli occupation.

    During the recent protests, Vuyiseka Dubula, General Secretary of the TAC, penned an article in which she called for protests “built on alliances, strategy, clear realistic demands and the genuine intent to improve the lives of people”. (...)

    Thus, what Vuyiseka, TAC and its affiliated NGOs are really saying is that communities should protest their way, should build alliances under their umbrella, and should make only ’realistic’ (reformist) demands that are acceptable to their vein of sectarian liberal politics. Yet their approach at donor-funded activism often does not work or is unaffordable to shackdwellers – thereby dictating who can afford to protest and actively preventing the formation of alternatives.

    Its expansion was frighteningly fast. A handful of cases were first recognized in the U.S. at the beginning of the 1980s, but AIDS was soon seen around the world.

    By 1990, the world had a pandemic on its hands. In 1997, the peak of the epidemic, more than 3 million people became newly infected with HIV.

    Then science struck back. Drugs approved for HIV treatment in the mid-1990s proved profoundly effective, transforming AIDS from a death sentence to a chronic illness. Those treatments, combined with an international commitment to manage the disease by providing access to free drug therapy, led to a steep drop in new HIV infections.

But molecular biologist Marco Ruggiero’s teaching activities will be more closely supervised in the future (...)
    The HIV Forum also said there were “many reasons” it too felt satisfied with the outcome, and the decisions were “precisely” what it had hoped to obtain with its letter. “Our target was not the career of someone, but the consistency of what is taught at the University of Florence with what thirty years of scientific research tells us about HIV,” it said. “[The result confirms] freedom of research and teaching must ‘move with the scientific method’.”
