LOWERING HIV RISK FOR SEX WORKERS, ANYONE?

LOWERING HIV RISK FOR SEX WORKERS, ANYONE?

Erle Frayne D. Argonza

Is there any enthused soul out there who may have some bright ideas about strategies to lower HIV risk for sex workers?

A grim ripper of a research shows the very high levels of HIV risks on sex workers. This research was done across the continents, involving 100,000 female sex workers across 50 developing countries, cross-analyzing 102 previous studies for that matter. The results show a truly grim situation for the HIV/AIDS front, with the sex workers serving as a focused vector of the ailment.

Let’s all face the fact: AIDS/HIV will be with us for some time yet, so no matter what heroic efforts are being done to stave off the pandemic it will wreak havoc on all societies and populations for some time. Unless, of course, that the context will radically change into a global situation where HIV will die out naturally such as the Earth’s sustained immersion in the photonic belt of the galaxy.

Below is a discussion of the said cross-analytic studies.

Study notes strategies to lower HIV risk for sex workers

Helen Mendes

4 April 2012 | EN

Female sex workers in low- and middle-income countries are nearly 14 times more likely to become infected with HIV than other women in these countries, according to a literature review by US scientists.

The review was carried out by researchers at the Johns Hopkins Bloomberg School of Public Health and published in The Lancet Infectious Diseases journal (15 March).

The authors analysed 102 previous studies representing almost 100,000 female sex workers in 50 developing countries. They found that in Asia, sex workers were 29 per cent more likely to be infected than other women in the region. In Africa and Latin America, sex workers were 12 times more likely to be infected than other women – and India, the female sex worker community was at a massive 50-fold higher risk of HIV infection than the rest of the country's female population.

India, along with Kenya and Brazil have, however, made some inroads into reducing infection levels among sex workers.

"We believe that these examples represent countries adopting necessary approaches," said Stefan Baral, the study's lead author.

Brazil's National STD/AIDS Programme works closely with sex workers to prevent new HIV infections. As well as running campaigns to promote prevention, Brazil offers free antiretroviral treatment.

"Because of their vulnerability, sex workers are a priority group, and we have projects specifically for them," Juny Kraiczyk of the Brazilian Ministry of Health told SciDev.Net.

"We act to strengthen sex workers' networks" and this involves "programmes of peer education and prevention in prostitution areas," he said, adding that such strategies had also helped reduce the stigma associated with the disease that would otherwise discourage women from coming forward for testing and treatment.

This need to destigmatise HIV infection led to Brazil turning down a US$40-million grant from the US Agency for International Development (USAID) in 2005 because it included a clause condemning prostitution.

"We work under the principle of not criminalising prostitution. We see these people as vulnerable, and not to be blamed for their increased risk. There are [other] factors, such as discrimination and poverty, which result in higher vulnerability for them," explained Kraiczyk.

The Lancet Infectious Diseases study found that in India, the country's Avahan and Sonagachi programmes have successfully tackled a range of structural challenges, through community empowerment, campaigns to address stigma, and the targeting of high-risk sexual practices with prevention messages.

"The disproportionate burden of HIV among sex workers … emphasises the need to increase coverage by increasing scale of prevention programmes and decreasing barriers to access," the study stated.

India is making the Avahan programme, which is funded by the Bill & Melinda Gates Foundation, a national initiative.

"Avahan has shared its approaches, tools, methods and strategies with the government, and many aspects have been incorporated into the national programme," Shelley Thakral, communications officer of the Bill & Melinda Gates Foundation in India, told SciDev.Net.

RE-ENGINEERING NIPPLE DEVICE TO AVOID INFANT HIV

RE-ENGINEERING NIPPLE DEVICE TO AVOID INFANT HIV

Erle Frayne D. Argonza

Breastfeeding by a healthy mother can yield enormous health and adaptability benefits for the fragile infant. However, an AIDS infected mother is a different story altogether, in that breastfeeding brings HIV harm directly to the infant.

Researchers are therefore challenged to innovate on a nipple device that can cut the infant infection by the mother’s HIV/AIDS condition. Time seems running out on the project, as 400,000 babies are infected with HIV across the planet every year.

A very interesting news about the subject is shown below.

Nipple device could deliver drugs to babies

Karen McColl

27 February 2012

A simple nipple shield could help breastfeeding mothers cut the risk of HIV infection from breast milk, say researchers.

Nipple shields are often used by mothers who have difficulty breastfeeding, and a modified version of the shield has been developed by a team of young engineers with a view to reducing mother-to-child HIV transmission.

The tip contains a removable insert, which can be impregnated with a microbicide designed to inactivate the HIV virus. The drug would be flushed out by breast milk as the baby feeds.

More recently, the team has been exploring whether a similar device could deliver antiretroviral drugs to breastfeeding babies, in light of changing advice from the WHO. The WHO now recommends that babies born to HIV-positive mothers be breastfed and simultaneously receive antiretroviral drugs, unless conditions are safe for formula feeding.

Globally, about 400,000 children a year are infected with HIV, nearly all acquiring the virus from their mothers. The risk of transmission is significantly increased by breastfeeding.

The only way to eliminate this risk is not to breastfeed, but formula feeding is often unsafe, expensive and impractical, especially in developing countries, where formula-fed babies face a higher risk of malnutrition, diarrhoea and other infections. This is particularly the case in Sub-Saharan Africa, where more than 90 per cent of mothers infected with HIV live.

A project to develop the modified shield, called JustMilk, was launched at the International Development Design Summit in 2008. The researchers say it may also be possible to produce inserts containing other medications or nutritional supplements.

The project has attracted much attention, including a US$100,000 Grand Challenges Exploration research grant from the Bill and Melinda Gates Foundation in 2009.

But Stephen Gerrard, a JustMilk researcher at the University of Cambridge in United Kingdom said more research is needed.

"We have to prove without a doubt that if this device is used by a mother, the volume of milk consumed does not change," he said.

Gerrard told SciDev.Net that trials to test this principle are expected to take place within the next year.

"I'm optimistic that we can do good with this device once we are sure that it does not impede breastfeeding and would not create any stigma," he added.

Andrew Tomkins, at the Institute of Child Health in London, said: "The potential problem with a nipple shield device will be making sure that the dose is adequate for the baby."

NO FIXED PATH TO HIV PREVENTION

NO FIXED PATH TO HIV PREVENTION

Erle Frayne D. Argonza

Could there be a single, most acceptable path to HIV prevention? This is the guide question posed upon those biomedical specialists and experts who are into HIV research & development as well as to the practitioners.

Long before the biomedical disciplines found the pharmacologic panacea to HIV, alternative health practitioners in Asia already found the cure to ailment which they tried on many patients in the 70s and 80s. Whether the biomedical fields will come to accept these non-conventional solution remains to be seen.

One thing is clear though at this juncture: that biomedical experts are now of the consensus that there is not a single megalithic path to HIV prevention. This is a welcome departure from the extremely positivist premise of biomedical paradigm which sought to reduce disease treatment to a single active ingredient from drug-based medication.

Below is an update report on relevant developments from the International AIDS Society or IAS.

Biomed Analysis: No single path to HIV prevention

Priya Shetty

22 July 2011

Excitement about new drug treatment for HIV prevention does not mean we should lose sight of other methods, cautions Priya Shetty.

Scientists trying to prevent people from becoming infected with HIV are on a roll. After a huge leap forward last year in AIDS vaccine research, when powerful sequencing uncovered potent anti-HIV antibodies, new research shows convincingly that treatment with antiretroviral drugs can also be used to prevent infection.

The latest results on the effectiveness of drugs for pre-exposure prophylaxis (PrEP), presented at the International AIDS Society conference (IAS 2011) in Rome this week, were released just a couple of weeks before. The finding that PrEP could reduce new HIV infections by up to 73 per cent was so compelling that the trial was halted early.

With such excitement over a preventive approach that we have available right here, right now, suddenly a vaccine might not seem like the holy grail of HIV prevention after all.

But the early days of HIV vaccine research are a cautionary tale. The assumption that a vaccine was just around the corner seemed to lead, initially, to complacency that might explain why it is only relatively recently that other approaches to prevention have been high on the agenda.

And at IAS 2011, there was a broad consensus that pursuing one approach does not render the others redundant — and indeed that it would be impossible to tackle a disease such as HIV/AIDS without several approaches.

Vaccine research gets a boost…

For years, HIV prevention has relied on non-biomedical, behavioural interventions such as condom use and safe-sex counselling. Since behaviour is difficult to change, such tactics are notoriously difficult to implement. Yet, for several years, they were the only weapons in the fight to prevent the spread of HIV.

Once scientists knew that HIV was the cause of AIDS, they were confident that a vaccine would soon be developed for the virus. But they had not bargained for its complexity — and AIDS vaccine research has been problematic from the beginning.

Most disease-causing viruses come in a few different strains; HIV has hundreds of them. Not only that, the virus is capable of changing its surface proteins to evade antibodies. Devising a vaccine against HIV is a huge challenge.

Speaking at IAS 2011, Gary Nabel, head of the US National Institutes of Health's Vaccine Research Center, which was set up in 1999 to find an HIV vaccine, described most of the time spent hunting for it as "the dark ages".

But last year, everything changed, said Nabel. The discovery of antibodies that worked against 90 per cent of HIV strains (compared with 40 per cent for previously found antibodies) has made the prospect of an HIV vaccine real again.

…but existing tools show promise

Even before the resurgence in vaccine research, male circumcision and microbiocide (disinfecting) gels had shown great promise in preventing infection. The WHO now says "there is compelling evidence that male circumcision reduces the risk of heterosexually acquired HIV infection in men by approximately 60 per cent".

Early clinical trials had hinted at the promise of treatment for prevention. And in the past few months, studies have shown that combination antiretroviral treatment (tenofovir/emtricitabine) reduced the risk of HIV-negative people becoming infected by 44 per cent in men who have sex with men, and by up to 73 per cent in heterosexual couples.

A key randomised clinical trial that was also presented at IAS 2011, called HPTN 052, showed conclusively for the first time that putting infected people on antiretroviral therapy early can reduce their chance of passing on the infection by 96 per cent.

Many paths to prevention

As thrilled as HIV researchers have been with the results of preventive drug trials, the implementation of treatment programmes will be far from simple. Developing countries have too few healthcare workers, and rolling out antiretroviral treatment can be logistically difficult — so adding treatment for prevention will add to already heavy burdens.

Deciding which groups are eligible for drug treatment, which means putting otherwise healthy people on powerful drugs, also raises ethical questions that are not easily solved.

Given these complexities, it would be short sighted not to pursue aggressively a vaccine that would confer lifetime immunity in one shot. Nor should the public health community abandon non-biomedical strategies such as condom use and reducing risky behaviour.

Safe sex is not just about HIV, after all — prevalence rates of other sexually transmitted diseases are on the rise in many developing countries, and rates of unwanted pregnancy remain high.

The take-home message from IAS 2011 is crystal clear. After years of struggle, we can now contemplate moving towards ending the epidemic. But we should not threaten the chances of success by playing off one approach against another.

MALARIA D’APES & MONKEYS

MALARIA D’APES & MONKEYS

Erle Frayne D. Argonza

We have a new alarming development concerning malaria spread. Gorillas and monkeys might just happen to be the dreaded carriers of the disease, a news that could cause chagrin on the legendary Tarzan.

This analyst has no fondness for Tarzan philosophy, but is more focused on highlighting risks to communities caused by a diversity of factors such as diseases. Being a development worker for long, I contracted malaria while doing field work and almost died of the falciparum disease in 1982.

We have no evidence yet of malaria being transmitted to humans by monkeys even though we do have species of monkeys among our diverse fauna. But Africa has shown less resiliency to that possibility, as shown in the report below.

Primate malaria in Africa may be jumping species

Rachel Mundy

7 July 2011

A malaria parasite from gorillas has been found in an African monkey, suggesting it has jumped species and may be able to transfer to humans.

The finding has led some malaria experts to suggest that if transfer between monkeys and apes has occurred then monkey-to-human malaria transmission may already be happening. They have called for more research to quantify the risks.

"The evidence is sufficient to warrant further investigation into the possibility that these parasites may also jump to humans," said Beatrice Hahn, a professor of medicine at the University of Alabama at Birmingham, United States. "We need to screen humans who live in flying range of mosquitoes that also bite primates, to establish whether they are susceptible to the primate parasites."

Wild forest-living gorilla populations are known to harbour a parasite strain that is closely related to the human malaria parasite Plasmodium falciparum. And macaque monkeys in South-East Asia carry another malaria parasite, Plasmodium knowlesia potential threat to humans.

But this is the first time that a P. falciparum strain similar to the one that causes human malaria has been found in an African monkey — the spot-nosed guenon from Gabon (Cercopithecus nictitans).

The fact that "the genetic differences from the human strain are so slight" raises the possibility that monkey and ape malaria may be transmitted to humans, said François Renaud, a researcher at the French National Centre for Scientific Research, in Montpelier, and co-author of the study published in the Proceedings of the National Academy of Sciences (5 July).

As humans come into closer contact with apes and monkeys as a result of deforestation, commercial hunting and population growth, the opportunity for the parasites to be transmitted to humans will increase.

"One single successful cross-species transmission event has the potential to result in a major human pandemic," Hahn, who was not involved in the study, told SciDev.Net.

But David Conway, professor of biology at the London School of Hygiene & Tropical Medicine, United Kingdom, said the reservoir of malaria in African monkeys must be very small, given the low prevalence found in this study.

"Hopefully, monkey malaria will start to be recognised as an important area of research, but when examining the public health significance for humans, it is important to put the risk into context. Normal human malaria has a much higher prevalence, except in parts of South-East Asia where this has been reduced and the importance of malaria from monkeys has become more noticeable," Conway said.

Looking for human infections with monkey malaria is "like looking for a needle in a haystack", he said, adding that "there is every chance that human infections are occurring occasionally in the forest".

"In this particular case, the vector of malaria is the key determinant in determining any public-health risk," Conway said. "Identifying which species of mosquitoes transmits each parasite strain is a neglected area of research that needs additional funding."

HEALTH & CLIMATE CHANGE

HEALTH & CLIMATE CHANGE

Erle Frayne D. Argonza


How does climate change dovetail into health, hygiene, and public policy concerns regarding healthcare?

The impact of climate change is surely very complex a matter, as it involves many intervening factors affecting epidemiology and ailments. Health perspectives must, first of all, be re-tooled to constitute emerging paradigms about the matter.

Below is an update report by the development group eldis.org. Country cases showing climate change impact on health are incorporated.

[Philippines, 08 July 2011]

ELDIS HEALTH REPORTER

  1. Predicting and mapping malaria under climate change scenarios: the potential redistribution of malaria vectors in Africa
  2. A human health perspective on climate change
  3. Impacts of climate change on public health in India: future research directions

Predicting and mapping malaria under climate change scenarios: the potential redistribution of malaria vectors in Africa

Authors: EZ Tonnang,Henri; YM Kangalawe,Richard; Z Yanda,Pius
Produced by: Malaria Journal, BioMed Central (2010)

This paper, published in the Malaria Journal, posits that malaria is rampant in Africa and causes untold mortality and morbidity. Since vector-borne diseases such as malaria are climate sensitive, the authors argue that this fact raises considerable concern over the implications of climate change on future disease risk, as malaria vectors (Anopheles mosquitoes) may shift from their traditional locations to invade new zones.

Exploiting the sets of information previously generated by entomologists, e.g. on geographical ranges of vectors and malaria distribution, the authors build models that will enable prediction and mapping the potential redistribution of Anopheles mosquitoes in Africa.

Key findings of this study are:

  • Shifts in the Anopheles mosquitoes species boundaries southward and eastward of Africa may occur rather than jump into quite different climatic environments.
  • In the absence of adequate control, these predictions are crucial in understanding the possible future geographical range of the vectors and the disease, which could facilitate planning for various adaptation options.

The authors conclude that the outputs from this study will be helpful at various levels of decision making, for example, in setting up of an early warning and sustainable strategies for climate change and climate change adaptation for malaria vectors control programmes in Africa.

A human health perspective on climate change

Produced by: Environmental Health Perspectives (2010)

This report, published by the the Interagency Working Group on Climate Change and Health, highlights 11 key categories of diseases and other health consequences that are occurring or will occur due to climate change.

The purpose of this paper is to identify research needs for all aspects of the research-to-decision making pathway that will help us understand and mitigate the health effects of climate change, as well as ensure that we choose the healthiest and most efficient approaches to climate change adaptation. This way, the authors provide a starting point for coordination of research to better understand climate’s impact on human health. The authors articulate, in a concrete way, that human beings are vulnerable in many ways to the health effects of climate change. They lay out both what we know and what we need to know about these effects in a way that will allow the health research community to bring its collective knowledge to bear on solving these problems.

The paper highlights the state-of-the-science on the human health consequences of climate change on:

  • Asthma, respiratory allergies, and airway diseases.
  • Cancer.
  • Cardiovascular disease and stroke.
  • Foodborne diseases and nutrition.
  • Heat-related morbidity and mortality.
  • Human developmental effects.
  • Mental health and stress- related disorders.
  • Neurological diseases and disorders.
  • Waterborne diseases.
  • Weather-related morbidity and mortality.
  • Vectorborne and zoonotic diseases (like malaria, which can be transmitted from animals to humans).

The report also examines a number of cross-cutting issues for research in this area, including susceptible, vulnerable, and displaced populations; public health and health care infrastructure; capacities and skills needed; and communication and education efforts.

The authors conclude that the actions we take today will help to shape our environment in the decades to come. Some degree of climate change is unavoidable, and we must adapt to its associated health effects; however, aggressive mitigation actions can significantly blunt the worst of the expected exposures.

They recommend research to identify who will be most vulnerable, and what efforts will be most beneficial; and to focus on the following areas:

  • Integrating climate science with health science.
  • Integrating environmental, public health, and marine and wildlife surveillance.
  • Applying climate and meteorological observations to real-time public health issues.
  • Down-scaling long-term climate models to estimate human exposure risks and burden of disease.

Impacts of climate change on public health in India: future research directions

Authors: F. Bush,Kathleen; Luber,George
Produced by: Environmental Health Perspectives (2011)

Building on the information presented at the 2009 Joint Indo–U.S. Workshop on Climate Change and Health in Goa, India, this paper reviews relevant literature and data, to address gaps in knowledge, and identify priorities and strategies for future research in India.

The authors argue that:

  • Climate change and associated increases in climate variability willlikely further exacerbate global health disparities. As such, moreresearch is needed, particularly in developing countries, to accuratelypredict the anticipated impacts and inform effective interventions.
  • The scope of the problem in India is enormous, based on the potential for climate change and variability to exacerbate endemic malaria, dengue, yellow fever, cholera, and chikungunya, as well as chronic diseases, particularly among the millions of people who already experience poor sanitation, pollution, malnutrition, and a shortage of drinking water.
  • In light of this realisation, the authors highlight the importance of improving the surveillance, monitoring, and integration of meteorological, environmental, geospatial, and health data while working in parallel to implement adaptation strategies.

Key conclusions and recommendations:

  • It is critical for India to invest in improvements in information infrastructure that are innovative and that promote interdisciplinary collaborations while embarking on adaptation strategies.
  • This will require unprecedented levels of collaboration across diverse institutions in India and abroad.
  • The ensuing data can be used in research on the likely impacts of climate change on health that reflect India’s diverse climates and populations.
  • Finally, the authors recommend the enhancement of local human and technical capacities for risk communication and promoting adaptive behavior.

The implications of climate change for health in Africa

Authors: Chimbari,M., J.
Produced by: Arid Lands Information Network (2010)

The interactions between health and climate change are clearly recognised; the Intergovernmental Panel on Climate Change includes a chapter on health issues in all its publications. But we still need to better understand all the possible impacts of climate change on health.

To date, much of the evidence of the health impacts of climate change has focused on malaria. But the impacts are much wider than this. Climate change projections for Africa indicate that temperatures will increase by 0.2–0.5°C per decade, and many African regions will experience more severe droughts. This will translate to a short growing season for food crops, thus leading to food shortages. These changes may affect human health directly, as the changing weather patterns encourage the production of disease vectors and parasites, such as those causing malaria. Indirect changes will result through impacts on water availability, air quality, food quality and quantity, ecosystems, agriculture and economies – all factors that affect people’s health.

This issue of Joto Afrika features articles from different countries, which highlight ongoing or completed research into climate change and health across Africa. These articles indicate:

  • climate change may increase the prevalence of diseases transmitted between humans and animals
  • children are most vulnerable to climate change; in times of food shortage, they must be well-fed to avoid malnutrition, as this can make them more vulnerable to other diseases
  • communities living in areas prone to flooding are often displaced, forcing them to move to temporary accommodation with basic facilities. This makes them more vulnerable to waterborne diseases
  • modelling is an important tool for early warning for climate-induced health disasters
  • vulnerable people in communities, for example people living with HIV, can develop successful coping strategies.

Climate change is a significant and emerging threat to public health. There is need for capacity building and implementation of projects to strengthen the health system response to climate change and to ensure that health is appropriately considered in decisions made by other sectors such as energy and transport.

17 NEGLECTED TROPICAL DISEASES AS GLOBAL KILLERS

17 NEGLECTED TROPICAL DISEASES AS GLOBAL KILLERS

Erle Frayne D. Argonza


World population today is nearing the 7 billion mark. 1/6 of our globe’s population, or roughly 1.4 Billion, is afflicted by a relatively short list of ailments known as ‘neglected tropical diseases’.

Let’s get this straight: such ailments afflict the ‘3rd world’ and emerging markets of today. A cursory review of what causes such ailments would reveal the most likely causes.

Below is an update report about the ailments.

[Philippines, 03 July 2011]

ource: http://www.devex.com/en/articles/75149

What Afflicts One-Sixth of the World's Population?

Dengue, leprosy, rabies - these diseases rarely make international headlines. But they, together with 17 other so-called neglected tropical diseases, are nearly four more times widespread than HIV/AIDS, tuberculosis and malaria combined.

Neglected tropical diseases are said to afflict almost a billion people around the globe - or an astounding one-sixth of the world’s population. That’s exactly 364 percent of the combined number of HIV/AIDS, TB and malaria cases, which were estimated at 274 million people in 2009. Yet, less than 1 percent of newly registered drugs are meant to address these tropical diseases.

Why are they being neglected?

“They are not highly visible,” the World Health Organization has said. “They do not cause explosive outbreaks that attract public and media attention. They do not travel internationally. They cause great and permanent misery, but do not kill large numbers of people or affect wealthy nations.”

Neglected tropical diseases largely prey on people who reside in remote rural areas and sprawling shantytowns, which typically lack safe drinking water and have poor sanitation, substandard housing and weak health care services.

Although many health experts have pointed out the need to address these tropical diseases - and cost-effective ways of doing so in conjunction with anti-malaria initiatives, for instance - donors have been slow to focus on this issue. But funding is available, with two of the world’s largest global health grant-making foundations – the Bill & Melinda Gates Foundation and the Wellcome Trust – as the campaign’s biggest patrons.

APOLOGIA & CURRENT TIDBITS

Erle Frayne Argonza

Good morning from Manila! Magandang umaga sa inyong lahat!

First of all, my apology for the quite long dormancy or near-absence in my own sites. A long story this is. Last January and February my family went on a mourning over the death of my father's 2nd wife. My Dad is now all alone, so I decided to join him in his Antipolo City suburban home, but in the process cutting off my DSL account in my old home (rented). I then decided to go on a contemplative couples of months to recollect my life journey and rechart my next steps. That now done, I am back in my blogs, though I had to be constrained by the fact that I'm doing this in commercial netcafes.

Many events have since passed, from the time I rested from my writing. Let me just cite two (2) events that raged the world as most noting:

  • Manny Pacquiao's great victory over his Brit competitor. My own kabayan Manny is now indubitably the best boxer in the world, and is for me indubitably among the world's greatest boxers. He is still moving up the scale of talents, and is reputedly improving yet by the day, which makes him truly a monster in the ring. The Manny fight is the best story to blast the planet so far, as far as culture & leisure is concerned. Well, it seems that it is in the culture sphere anyway where the positive news are churned out, thus reducing effectively the dreariness of a dreadful world getting more mad each day.

  • HIN1 Virus on the loose. Coming straight from Dostoevskian and Malthusian hells, this pandemic suddenly burst forth into the public mind in a rather unexpected manner. Well, pandemics are as unexpected as they can be, unpredictable in their onslaughts, so here we all are waiting for the manna from heaven (i.e. antivirus serum) that could take this virus down once and for all and spare us all the stress and storm that is raging the planet economically.

That said, let me say, I am so glad to be back. Please stand by for exciting notes I'd be sharing afresh to you all.

Carpe diem!
