HIV Hides Out

8 03 2010

Today, most people who are HIV+ take numerous drugs to control the virus, and they do so for the rest of their lives. Once those drugs start working, their bloodwork typically shows they have no virus in their bodies.

Problem is, the virus is still in the body. It’s just hiding out and sleeping.

The latest hiding place discovered is bone marrow. HIV stays in bone marrow cells and, when those cells develop into blood cells, the virus wakes up, kills those new blood cells, and actively seeks to kill other cells.

Scientists have to figure out how to stop HIV from hiding out in the bone marrow.

They have to find all the hiding places of this virus. When they do, and they discover how to stop the virus from hiding in those places, those who are HIV+ can at some point stop taking drugs, rather than staying on them for life.

What a difference that will make!

Haitians Suffer From Lack of Coordinated Relief Efforts

Weeks of misery are stretching into months for the people of Haiti.

With well over 200,000 deaths, untold numbers of lingering injuries, and more than one million homeless, Haitians need the efforts put forth by the world’s people to make a  difference, to get them on the road to recovery.  But those efforts are falling short.

The biggest obstacle has been and continues to be a lack of coordination between the many civilian and military agencies providing assistance.

The problem isn’t that there’s no one to lead—there are many capable and qualified groups and individuals to lead global emergency response efforts.  The problem is getting the rest of the responders to follow a leader from an agency other than their own.

A recent Associated Press article reported that Haitians have enough rice and beans, but are running short on other items critical to survival, such as tents, tarps, and toilets.

The World Health Organization (WHO) is immunizing unvaccinated Haitians against measles, tetanus, diphtheria, and other diseases, but officials worry that the approaching rainy season will bring with it a sharp increase in respiratory infections and malaria cases.

Despite some successes, aid organizations receive thumbs down for the poorly-planned distribution of the first wave of food supplies, and the continuing lack of coordinated efforts which leave people in need with no shelter, no clean water, and no sanitation system.

So, what are the answers?

A better plan of action for first responders

Many countries have called for a more unified response. Rather than several military forces, charities, and organizations scrambling to help and stepping on each other’s toes, ideas for streamlining relief efforts have included forming giant response teams based on geographic area, or giving the U.N. more power to direct a global response.

Making the affected country’s government central to the relief effort

Wary of eyes watching for signs of an “occupation,” it is generally agreed that it’s crucial for the local government to be restored to get normal operations up and running as soon as possible.

Establishing a compromise between military and civilian organizations

The U.S. military, considered the most equipped to help due to Haiti’s nearness, has not offered a summary of what equipment and technology are available for relief efforts. It was criticized for slowing down entry of supply shipments in the early days of the crisis and for not communicating with the U.N. Although some problems have been remedied (the U.S. agreed to give priority to aid shipments rather than military flights), it is still a long way from integrating with other aid organizations.

It may be tempting to wash our hands of this mess, but if we do, the Haitians will be the losers and there will be no winners.

Contact your representatives and insist they improve coordinated efforts in Haiti.  And, please keep giving to the Haitian people.  We can’t turn away from so much need. Please look for a reliable charity or organization and continue to support work being done to restore and rebuild Haiti.

Less is More?

1 03 2010

Don’t you love it when health experts tell us that we need to spend less time exercising?  This good news comes with a warning: consult your physician before starting any new physical activity.

Interval training is 45 minutes of short bursts of intense exercise a week. This takes the place of the 2.5 hours of weekly exercise recommended in Britain and the U.S.

Will it work on middle-aged people who sit at a desk all day, or will it just give us all heart attacks?  More studies are needed.
