Millions at risk as effect of anti-malaria drugs weakens

Millions at risk as effect of anti-malaria drugs weakens

A deadly form of malaria has developed a resistance to the most powerful drugs used to treat the disease, putting the lives of millions of people around the world at risk. 

Tests by a team of British and Thai scientists over a 10-year period found the most dangerous species of malaria parasites, spread by mosquitoes, are becoming more resistant to the most effective treatments containing artemisinin, a drug derived from the sweet wormwood shrub. 

They discovered that Plasmodium falciparum, which was first reported in 2009 in western Cambodia, is now being found 500 miles (805 kilometers) away on the border of Thailand and Burma. 

The details of their findings and research, published in The Lancet medical journal, showed that between 2001 and 2010, the average time taken to reduce the number of parasites in the blood by half following treatment rose from 2.6 hours to 3.7 hours. 

The proportion of slow-clearing infections increased during the same period from six to 200 out of every 1,000 cases. 

Study leader Professor Francois Nosten, director of Thailand's Shoklo Malaria Research Unit, warned of a "race against time" to halt the spread of the potentially untreatable malaria. 

"We have now seen the emergence of malaria resistant to our best drugs, and these resistant parasites are not confined to western Cambodia," he said.
 

Living alone 'are more depressed'

Category: , By News Updater

People of working age who live alone increase their risk of depression by up to 80% compared with people living in families, says a Finnish study. Similarly, research teams on top psychology schools also found out that elderly people living alone are more at risk for depression and mental health problems.

It says the main factors are poor housing conditions for women and a lack of social support for men, who are both equally affected.


The study tracked the use of anti-depressants in 3,500 Finnish people.


A mental health charity said people who lived alone must be given outlets to talk about their problems.


The study authors highlight the fact that the proportion of one-person households in Western countries has increased during the past three decades, with one in every three people in the US and the UK living alone.


The participants in the study, published in BioMed Central's public health journal, were working-age Finns; 1,695 were men and 1,776 were women, and they had an average age of 44.6 years.

Loneliness and isolation results in people having fewer outlets to talk about how they are feeling, which is something that we know can really help.”

They were surveyed in 2000 and asked whether they lived alone or with other people.


Other information about their lifestyle was gathered, such as social support, work climate, education, income, employment status and housing conditions, in addition to details on smoking habits, alcohol use and activity levels.


Researchers found that people living alone bought 80% more anti-depressants during the follow-up period, between 2000 and 2008, than those who did not live alone.


Dr Laura Pulkki-Raback, who led the research at the Finnish Institute of Occupational Health, said the real risk of mental health problems in people living alone could be much higher.


"This kind of study usually underestimates risk because the people who are at the most risk tend to be the people who are least likely to complete the follow up. We were also not able to judge how common untreated depression was."
Isolation


Researchers said that living with other people could offer emotional support and feelings of social integration, as well as other factors that protect against mental health problems.


Living alone, the study said, could be linked with feelings of isolation and a lack of social integration and trust, which are risk factors for mental health.


The study said all the factors involved needed to be addressed in order to understand and reduce depression in working-age people.


Beth Murphy, head of information at mental health charity Mind, said the rise in the number of people living alone had had a clear impact on the nation's mental health.


"Loneliness and isolation results in people having fewer outlets to talk about how they are feeling, which is something that we know can really help to manage and recover from a mental health problem.


"It is therefore essential that people who live alone are given the most appropriate treatment such as talking therapies, which provide safe, supportive environments to discuss and work through problems, rather than simply being left to rely solely on antidepressants."

Establishing long-term mental health care in flood-affected areas in Brazil

Category: By Echo
It was great to see the local and national mobilization to respond quickly to this type of emergency. But it is crucial that mental health care is integrated into the response early on to reduce the risk of other reactions such as post traumatic stress disorders at a later stage.

Dr. Sérgio Cabral, who coordinated MSF’s activities in the region north of Rio de Janeiro, Brazil, after recent floods, explains the scope of MSF activity during the natural disaster. After training over 150 psychologists in four towns, MSF is preparing to leave the area knowing the work will be continued.

Why has MSF decided to respond to the floods in Brazil?
“We came soon after the floods to do an assessment and were shocked by the extent of the disaster. I was also impressed by the volume of aid arriving in some towns, resulting from a massive mobilization by the population, other organizations and the state itself. However, in more isolated place, the population was stranded and their access to basic medical care was limited. In those places, like Sao Jose do Vale do Rio Preto, aid was much slower to arrive.”

What has MSF done?
“We have sent two additional teams with doctors, psychologists and a nurse to provide medical and psychological care in the most affected areas. But the volume of aid increased quickly, even in the isolated places. Unfortunately, mental health care was virtually non-existent so that is where we decided to focus.”

How have you done it?
“There were many skilled psychologists but most had never worked in a context of natural disaster, so they felt unable to help the survivors. Many had also been affected by the floods or mudslides and were extremely shaken by the disaster, and that initially hampered their ability to provide mental health care to those who had gone through the same experiences. We started by meeting groups of psychologists who were working in the area and, together with them, we decided that the best thing to do was to provide training on how to deal with survivors of this type of disaster. These psychologists were working for other organizations or for the public health system. And they will remain in the area after MSF leaves.”

How big is the team now?
“We have three psychologists with previous experience in other natural disasters – like the Haiti earthquake or another flood response in Brazil. When you work with other psychologists, the impact of your work multiplies. We have also seen an increased interest in the training. At the first meeting in Friburgo there were 20 people. On the second day, the number doubled. In total, more than 150 psychologists have participated in the training sessions we provided.”

Is this a usual strategy for MSF?
“In this case, where there were very skilled local workers and a large number of committed volunteers who are able to respond quickly, it was an appropriate strategy to adopt. MSF also works on capacity building.”

What has been the main lesson learnt?
“It was great to see the local and national mobilization to respond quickly to this type of emergency. But it is crucial that mental health care is integrated into the response early on to reduce the risk of other reactions such as post traumatic stress disorders at a later stage.”
 

Ayurvedic medicines face EU ban from May 1

Category: , , By Echo
A ban on the sale of Ayurvedic and other herbal medicines will take effect across Europe from May 1 following a European Union directive introduced as a response to growing concern over adverse effects of such
alternative medicines.

Users and promoters of such medicines have called the EU directive called The Traditional Herbal Medicinal Products Directive, 2004/24/EC, "discriminatory and disproportionate".

Ayurvedic and traditional herbal medicines will need to licensed to comply with the EU directive passed in 2004, which takes effect from May 1.
 
 
 
Official sources said those ayurvedic products marketed before the legislation came into force in 2004 can continue to market their product until April 30, 2011, under the transitional measures.
Once this time limit has expired, all herbal medicinal products must have prior authorisation before they can be marketed in the EU. Ayurvedic medicines such as "ashwagandha" will not be available for sale across Europe from May 1.
The directive aims to protect users from any damaging side-effects that can arise from taking unsuitable medicines.
The UK Medicines and Healthcare Products Regulatory Agency (MHRA) has issued more than a dozen safety alerts in the past two years, including one over aristolochia, a banned toxic plant derivative, which reportedly caused kidney failure in two women.
After the ban comes into effect, only high quality, long-established and scientifically safe herbal medicines will be sold over the counter, official sources here said.
Herbal practitioners say it is impossible for most herbal medicines to meet the licensing requirements for safety and quality, which are intended to be similar to those for pharmaceutical drugs, because of the cost of testing.
According to the Alliance for Natural Health (ANH), which represents herbal practitioners, not a single product used in traditional Chinese medicine or ayurvedic medicine has been licensed.
Producers and independent health store owners allege that the directive draconian and favours large European manufacturers, but smaller firms will be in danger of being squeezed out of the market.
Under EU law, statutorily regulated herbal practitioners will be permitted to continue prescribing unlicensed products, but the government in Britain has delayed plans to introduce a statutory herbal practitioner register.
