As Economy Suffers, Sex Industry Continues to Thrive

With the economy seemingly out of control across the globe, there is one industry that has continued to thrive: the sex industry. Unfortunately, as the industry thrives, so does the transmission of HIV. With that in mind, groups of researchers hailing from the University of California at San Diego School of Medicine, the University of California at Davis, Northeastern University and several teams across Mexico joined forces to perform a study on female sex workers living in Ciudad Juarez and Tijuana, Mexico. With the desired outcome of slowing down the rapidly rising HIV and sexually transmitted diseases rates in the border towns between Mexico and the United States, this research team has determined that in order to reduce HIV and STD rates and increase condoms use, female sex workers should receive a short, personal counseling session geared towards impacting their current and future behaviors.

After beginning these 30 minute private sessions, researchers noted an almost 40 percent decline in the rates of new sexually transmitted diseases, including Chlamydia, HIV, gonorrhea and syphilis. This was in direct comparison to a session that involved distributing educational material only to the sex workers. The study's lead author, Thomas L. Patterson, states, "An advantage to the counseling approach is that - instead of simply listening to a lecture - women are taught and can practice skills that are tailored to their personal situations. By working with the counselor, women identify for themselves the barriers to safer sex and discuss potential solutions as part of their goal setting." The study had close to 1000 participants and was geared to those female sex workers over the age of 18 who were not currently infected with HIV but who admitted to having sex with clients without using contraceptives, like condoms. The women were split into two groups with one half participating in the Healthy Woman (Mujer Segura) personalized counseling session and the other half participating in the sessions where educational material was distributed.

According to Patterson, "The major difference in the two approaches is that the Mujer Segura sessions focused on the participants assessing their personal risk factors, such as having unprotected sex with clients, and developing strategies for reducing that risk." Of those who participated in the Healthy Woman sessions, there were no cases of new HIV infections and there was a significant decrease in risky behavior. Those participants in this session were given positive feedback and taught to set and work towards small goals in their quest to practice safe sex. Patterson continues, "In the absence of an effective HIV vaccine in the near future, the urgent need continues for effective, culturally appropriate interventions that can be used as stand-alone programs, or to support existing approaches. Our brief intervention, which counselors can be easily trained to deliver in a variety of settings, is an inexpensive and effective approach to reducing the risk of HIV and other STIs. These are diseases that recognize no borders, and it is critical that we work alongside health providers in Mexico to stem this disturbing trend."

HIV and AIDS: What's the difference?

Many of us, me included, use the terms AIDS and HIV interchangeably, not fully realizing how very different the two are. HIV (human immunodeficiency virus) is the virus that can evolve into AIDS (acquired immunodeficiency syndrome), while AIDS is the syndrome in which the sufferer’s immune system stops working which often proves fatal to the carrier. Without any type of medication, the average time for HIV to develop into AIDS is approximately nine or ten years. Once a patient is diagnosed with AIDS, the average survival span is just over nine months. So, at what point does HIV spiral into AIDS?

Research from an August 2007 study done by UC Irvine demonstrates how HIV transitions into AIDS and offers a way to perhaps halt this transition in HIV patients. One breakthrough involves how HIV evolves within a patient. Most scientists subscribe to the belief that AIDS develops as the HIV virus begins to evolve and starts spreading at the cellular level in a more efficient manner; however the UC Irvine suggests the opposite is true. Their research indicates that once the virus has evolved into a state where it is spreading less efficiently at a cellular level, then AIDS has the chance to truly develop. In addition, a process called co-infection must occur. What this means is that several HIV units must infect singular cells to turn HIV into AIDS. If only one HIV unit infected a singular cell, more than likely, AIDS will not be able to evolve. What this suggests is if researchers are able to stop more than one HIV unit from infecting a singular cell, AIDS could be stopped dead in its tracks. Dominic Wodarz, a UC Irvine biologist working on this study explains, “If this is true, a new approach to therapy could be used to block the process of co-infection in cells. This would prevent deadly HIV strains from emerging and the patient would remain healthy, despite carrying the virus.”

When a person contracts HIV, there are three phases that occur. The first phase takes place in the initial weeks of infection. At this point, the level of the virus within the infected person’s system spikes and symptoms very much like the flu begin to appear. The second phase is called the asymptomatic phase. During this second phase which lasts anywhere from eight to ten years, the level of the virus in the system begins to diminish. In the third and final phase, the transition to AIDS begins and the infected person’s immune system begins to disintegrate. With no immune system, a person is susceptible to many types of infections and death usually occurs.

Research studies to this point had not definitively determined at what point the asymptomatic state progresses into the final phase of AIDS. As mentioned earlier, many scientists believed that as in evolution, the virus grew stronger and was better able to grow, thereby causing HIV to transition. The model developed by Wodarz, however, counteracts this belief. His model which demonstrates the virus spreading and the speed at which it destroys cells suggests that when HIV turns deadly, the strains that kills are not the ones that are the fastest spreading, but rather the slower spreading ones. Wodarz proposes that with further positive testing of this theory, AIDS researchers may be able to devise a drug that prohibits more than one HIV unit from infecting a cell. Thus, the transition to AIDS would not occur.

HIV Antiretroviral Treatment Improving, with Fewer Side Effects

Antiretroviral drugs have helped those infected with HIV live longer and fuller lives, helping its patients maintain their infection and releasing AIDS of its death sentence status; however, the drugs that comprise the antiretroviral treatment are extremely strong and often carry intimidating side effects, which had some researchers wondering if perhaps newly infected patients should hold off on starting a drug treatment so soon after diagnosis. The debate has gone back and forth, but there may be some hope on the horizon. The pharmaceutical company that has recently had two new HIV drugs approved is reporting that they have fewer serious side effects than the drugs currently on the market.

These two new drugs were approved for those infected patients who were beginning to develop a resistance to their normal drug cocktails and also for any newly infected patients. These claims were made at a conference held in Washington, D.C. for specialists in the field of infectious diseases. Dr. Robin Isaacs, an executive director at Merck & Co, the company that funded the studies, stated, “There was a desperate unmet medical need for those patients who had failed other therapies.” The drugs that were studied were Isentress (developed by Merck & Co) and Selzentry (developed by Pfizer Inc.); they join three other drugs that might be more easily tolerated by patients, including Aptivus (developed by Boehringer Ingelheim), Prezista and Intelence (both developed by Johnson & Johnson). Isaacs went on to say, “They have all these different options now, which they didn’t before, to build new successful regimens.”

Merck & Co are hoping that Isentress will be granted first-line approval very soon; being an integrase inhibitor, it is the only one of its kind currently being offered. The drug works by stopping the integrase enzyme; this enzyme is responsible for putting HIV’s DNA within a patient’s cells and multiplying the virus. The study sponsored by Merck & Co surveyed over 550 patients. One half of these patients were given Sustiva (developed by Bristol-Myers Squibb Co) and the other half was given Isentress. Both sets of patients also took the Truvada drug as part of their treatment. While both sets of patients had similar levels of the virus after 48 weeks, only 44 percent of those patients that took Isentress reported serious side effects compared to 77 percent of those patients taking Sustiva.

Pfizer Inc had its own study done for its drug Selzentry. In this similar study surveying over 400 patients over 48 weeks, half of the patients received Selzentry and Combivir and the other half of the patients received Sustiva and Combivir. Again, the virus levels were similar, but of those patients receiving Selzentry, only 4 percent reported side effects serious enough to stop the drug treatment compared to 14.2 percent of those taking Sustiva. The Selzentry drug helps patients protect their immune system from the virus by essentially inhibiting or “closing the door” known as the CCR5 co-receptor.

African Fertility Clinics for AIDS Patients

For decades, AIDS has spread across the globe, leaving devastation and death in its path. However, no continent has been harder hit than Africa. Of the roughly 33 million people living with HIV/AIDS today, approximately two-thirds of those reside in Africa. Glancing over the statistics, especially those dealing with children who are infected with the virus, is eye-opening and saddening. In South Africa alone, over 250,000 children are suffering from the virus; close to 2 million children live with HIV in all of Africa. It is enough to make the heart break. Now, there is a tiny glimmer of hope in Cape Town, South Africa. A fertility clinic located in this region has recently begun offering the chance for couples who are infected with HIV/AIDS to have healthy children.

This clinic, the Cape Fertility Clinic, is the first of its kind of Africa. It allows would-be parents who are infected with HIV (either both parents or just one) to use measures like in-vitro fertilization to have the opportunity to give birth to children who are free from the disease. Klaus Wiswedel, a director at the clinic, states, “HIV is no longer seen as a death sentence but a chronic disease. And people with chronic diseases are entitled to have fertility treatment. We can safely deliver an HIV negative child and, with the right treatment, the parent can live a long life." While the clinic caters to those couples who can actually afford these procedures, they still have at least five couples coming in and paying for the procedures each month. Some critics would argue that this is small beans in comparison to the number of children born each month with the disease, but many who support the clinic see it as a reflection of the strides Africa is making in protecting both adults and children from HIV.

Consider the fact that only five years ago, 100,000 people in Africa were on AIDS drug treatments. Today, that number has grown dramatically to roughly two million people. In addition, due to increased funding and donations, infected pregnant women receiving AIDS treatments to help shield their unborn children from the disease has grown by leaps and bounds. In 2003, only five percent of infected pregnant women in Malawi were receiving treatment and that number has grown to 32 percent only 4 years later. Other success stories can be seen in Mozambique (three percent to 46 percent), South Africa (fifteen percent to 67 percent) and Zambia (eighteen percent to 47 percent) over the same timeframe. The executive director on UNAIDS, Peter Piot, states, “The prevention of mother-to-child transmission of HIV is not only effective, but also a human right. We are seeing good progress in many countries, especially in parts of Africa, but we need to significantly scale up HIV testing and treatment for pregnant women."

The new fertility clinic feels that anybody who wants children should have the opportunity to have a healthy child and should not be denied that right. The clinic utilizes artificial insemination when the mother-to-be is HIV-positive; if the father-to-be is HIV-positive then the sperm is cleansed of the virus. Once the couple has conceived they are monitored by a specialist and then deliver by C-section so that the infant is less likely to have the virus transmitted to them. Wiswedel states, "We jumped into the deep end of the pool because more and more patients want to receive treatment. We saw a huge need for this."

3 Myths about Condoms

Condoms have become a big part of life today, but there are still many people that refuse to see the benefit these particular contraceptives bring to the marketplace. People that are against condoms for political or religious reasons tend to perpetuate myths about them. For that reason many people are confused through no fault of their own when it comes to considerations regarding this product. In order to help clear the air a little bit, here are some of the more common myths perpetuated about condoms.
Myth #1: They make sex less enjoyable
This used to be true when condoms first came out onto the market, but the free market being what it is, this was ratified by the condom creating companies when they realized that it was indeed something that was starting to impede their sales. There are now condoms that are ribbed to increase the sexual pleasure a woman can get out of the act as well as ones that are ribbed on the inside to provide that same stimulation for the man. There are flavored condoms that make oral sex a lot more interesting. There are in fact a multitude of different options available for condoms nowadays that really have turned this partial reality into a complete myth.
Myth #2: They do not work
This used to be the biggest myth that was perpetuated regarding condoms, but as the general public has become more knowledgeable regarding matters of contraception, this myth has really collapsed. For this reason, people against the use of condoms will usually resort to myth #1 before this one nowadays. Condoms are one of the most reliable products around and this statement has been continually backed up by facts on a regular basis. When used properly, condoms are usually over 99.9% effective on average. In other words, condoms are basically foolproof when they are employed as the instructions indicate. If condoms are combined with other birth control methods however, they are even more effective.
Myth #3: They are expensive
Expensive is a word that is really a matter of opinion and for this reason one can not entirely call this a myth. There are probably some people out there that would view the cost of condoms as one that is far too expensive. That having been said however, when the packages are purchased, the individual condoms within them usually work out to something like pennies per condom, with individual packages often being sold for something like twenty-five cents per package. For this reason, most people that have experience with the full range of contraceptives would regard condoms as being relatively cheap to purchase.
Conclusion
For all of the reasons stated above in the debunking of those three myths, it is quite clear to anyone that has experimented with different safe sex methods that the condom is one of the most reliable and most cost effective methods out there. This is why in spite of the development of other methods over the years, this particular method has endured for such a long time.

Condoms - The Successive Steps of AIDS Prevention

AIDS has long been a source of intense concern on the international scale, but as time has gone on there have been many advances both in sociological changes and in behavioural changes that have helped to neutralize this particular illness in many areas of the world. AIDS prevention is therefore a successful endeavour if done correctly and while more permanent and better AIDS prevention methods are being developed, it behoves us as a population to try and utilize the AIDS prevention methods we currently have in order to try and reduce the spread of this illness as much as possible. To that end, there are several steps that you can take in order to help the AIDS prevention cause.
The first and most obvious step in terms of AIDS prevention is to simply abstain from having sex altogether. This is of course an activity that few people have the ability to do, but there are some for which sex is really not that big a priority and those people can protect themselves to a larger degree by making sure they avoid sex whenever they can. Avoiding sex alone will not make you 100% immune to catching AIDS, but it will go a long way towards helping ensure that your AIDS prevention efforts are successful in some way, shape or form.
For people that are simply not going to be able to avoid sexual activity for one reason or another, a much more reasonable step to take might be to cut down on the number of sexual partners that you have. The number of times you have sex with a different person can drastically contribute to an increased chance of contracting AIDS and for that reason ensuring that you are in a monogamous relationship or at least taking measures to reduce the number of sexual partners you have can go a long way towards helping you cut down on your chances of contracting AIDS.
If you decide to cut down on the number of sexual partners you have however, you will need to do something else in order to help your AIDS prevention efforts along. A good idea would be to wander into the realm of contraceptives and start utilizing them as a way to augment your protection against the AIDS virus. Condoms, diaphragms or any other contraception method that prevents the mixing of fluids would be suitable if your main goal is AIDS prevention. There are other birth control methods on the market such as pills that are not effective for preventing STD transmission for the simple reason that they do nothing to prevent the mixing of fluids which is where all of these diseases come from in the first place.
Preventing the spread of AIDS is something that everyone should be interested in if for no other reason than to ensure a higher standard of living. Smart sex and safe sex rather than unprotected sex is such a small price to pay for something as important as preventing the spread of AIDS.

Scouts Given Condoms to ‘Be Prepared’

The British Boy Scout Oath pledges that a Scout will perform his duty to God, his country, his fellow scouts and other people in addition to keeping himself “physically strong, mentally awake and morally straight.” He also lives by the motto to always “be prepared.” In an effort to help scouts live up to these goals and always be prepared for anything, the Scouting Association of Britain is urging that young Scouts between the ages of 14 and 18 add outings to sexual health clinics to their yearly trip agenda.
In an effort to get young Scouts to open up and be more at ease in discussing sexual topics with other members of the Scouting group, the Scouting Association is recommending these visits to health clinics. The association feels that by visiting the clinics, it may help “break illusions of what these services are and improve the uptake of advice.” Peter Duncan, a Chief Scout, is realistic about the situations young teenagers face in their daily lives, “We must be realistic and accept that around a third of young people are sexually active before 16 and many more start relationships at 16 and 17. Scouting touches members of every community, religious and social group in the country so adults in Scouting have a duty to promote safe and responsible relationships and, as an organization, we have the responsibility to provide sound advice about how to do that."
The association has stated that leaders of Scout troops may distribute condoms - Durex condoms, to be precise - to Scouts only on the condition that “they believe the young person is very likely to begin or continue having intercourse with or without contraception.” If the Scout leader feels that the “physical or mental health are likely to suffer” for one of their Scouts, they can go forth and distribute condoms to that particular Scout. Furthermore, the association urges Scout leaders to “encourage young people to resist pressure to have early sex.” If necessary, the leader can open up a dialogue with the Scout’s parents or guardians to discuss any concerns; however, the leaders “should be prepared to offer appropriate information” to the Scout if he is asked.
Duncan states, "I firmly believe that the confidence, skills and self esteem young people gain through the incredible range of activities Scouting offers is the best way to equip them not to feel pressured into a sexual relationship before they are ready." In addition, Beverly Hughes, the Minister for young people, has voiced her support of the association’s new policies, “While our teenage pregnancy rates are coming down and are at the lowest rate for over 20 years, there is much more to do to ensure young people have the knowledge of safe sex and they need to prevent early pregnancy and look after their sexual health."
