I have refrained from commenting on healthcare reform until now because there wasn’t much I could add to the debate. That said, while reading an article in a local paper on bacterial antibiotic resistance and how to minimize it, the author—an infectious disease doc—offered a telling statistic that identified the root problem with our current healthcare system. According to the article, 65% of the time, physicians will prescribe antibiotics to patients suffering from upper respiratory tract infections who demand them, whether or not they are warranted. In marked contrast, 12% of patients with upper respiratory tract infections who don’t ask for antibiotics receive antibiotic prescriptions. The bottom line: physicians give patients the drugs and treatment they demand because they are afraid of losing them as customers knowing full well the patients will go to another physician who will give them what they want! After all, physicians are in business and to stay in business they need to make enough money to cover their overhead and make a profit. However, over prescribing antibiotics is one of the main reasons why we are in the midst of an epidemic of infections caused by multiple drug resistant bacteria. In my opinion, business outcomes should never supersede or trump medical or public health outcomes.

Don’t get me wrong, I am an entrepreneur and believe that people with good ideas ought to be rewarded for their efforts and make as much money as they can. However, in my opinion, for profit business practices and healthcare haven’t historically worked well for the American healthcare system. Removing profit incentives from healthcare would be an important first step to begin to repair our broken healthcare system. Can anybody say public option?

Until next time...

Good Luck and Support the Public Option!!!!

The media frenzy surrounding the impending H1N1 swine flu pandemic has spawned a recent spate of articles and television news segments on “germs.” In the last 48 hours, articles on germs have appeared in the New York Times, my local paper (The Trenton Times via the Chicago Tribune), on news channels and most recently this morning on the Today Show on MSNBC. Most of these have focused on where “germs” are found, how they are spread and ways to minimize or prevent their transmission. For those of you who may be interested, the word germ was first coined in 1664 and is defined as a “small mass of living substance capable of developing into an organism or one of its parts” or more conventionally, as a “microorganism that causes disease.” While these media pieces are intended to inform the public about infectious agents and their transmission, most people who read or see these reports don’t understand that the word germ can encompass viruses, bacteria and fungi. And, to make matters worse, most Americans don’t know that viruses, bacteria and fungi are different microorganisms.

Unfortunately, after reading newspaper articles and seeing reports on television about so-called germs, many consumers rush out to their local groceries and purchase a variety of antibacterial soaps and detergents—erroneously believing that these products will protect their families from infection by the dreaded H1N1 virus and other pathogens. Although frequent hand washing and the appropriate use of viricidal disinfectants can help to reduce transmission of H1N1 and other viruses, antibacterial products are generally less effective (or ineffective) against viruses and overuse can result in emergence of multi-drug resistant bacteria.

To that end, I think it is high time that the news media eschew the use of the anachronistic term germ in favor of bacteria, virus or fungi when referring to causative agents of infectious diseases. Promulgating the use of the word germ will continue to keep the lay public in the dark about infectious agents and the diseases they cause and hinder people from making informed decisions about treatment and preventing their transmission.

Until next time...

Good Luck and Good Job Hunting!!!!

Several weeks ago, I blogged about a growing need to improve the American public’s perception and understanding of the life sciences if the US wants to remain competitive in science and technology. Much to my delight, there was an article this Sunday’s NY Times entitled “Microbes R Us” which explores the evolutionary relationship with bacteria and humans. It was written by Dr. Olivia Judson an evolutionary biologist and author of “Dr. Tatiana’s Sex Advice to All Creation: The Definitive Guide to the Evolutionary Biology of Sex,” which was made into a three part television program.

While the evolutionary relationship between bacteria and humans isn’t as titillating as the biology of sex, the article sheds light on the importance of bacteria and how genetic changes in bacteria that normally inhabit the human intestinal track can have a positive impact on human nutrition and health. Many lay people believe that bacteria are “bad” because certain species can cause serious and potentially life threatening diseases. However, the benefits, advantages and uses of bacteria e.g., to make food, antibiotics and other medicines, far outweigh their negative impact on society. 

Articles like the one written by Ms. Judson, offer the public unqique insights into  the amazing and often fascinating world of microbiology. I hope that a few aspiring young scientists read the article and tell all their friends about it!

Until next time....

Good Luck and Good Reading!!!!!!

Salmonella enteriditis, an organism dear to my heart (luckily not my posterior small intestine) is a common cause of food poisoning. As some of you may know, I did my PhD thesis work on Salmonella gastroenteritis (aka food poisoning) and I like to think that I am something of an expert on the topic. 

Typically, Salmonella food poisoning outbreaks are localized and rarely reach epidemic proportions. However, there have recently been two major nationwide Salmonella outbreaks in the US —one in 2007 and now in early 2009.

The current outbreak has afflicted 388 people in 42 states and may be caused by the same strain (Saint Paul) that was responsible for the 2007 outbreak. Ultimately, the 2007 outbreak was linked to contaminated tomatoes. The jury is still out on the cause of the most recent outbreak. Needless to say, CDC scientists are scurrying to quickly identify the source of the current outbreak because it took the agency over 5 months to conclusively identify the culprit in the 2007 epidemic. Not surprisingly, many grocery stores and restaurants suffered financially because of the outbreak.

Many of you may be wondering why Salmonella food poisoning is becoming such a problem in the US. I don’t believe that the strains responsible for the most recent outbreaks are more virulent than the ones that have traditionally caused more localized outbreaks. Instead, the reliance of food manufacturers and grocery store chains on one or two major food distributors (rather than multiple suppliers) is likely responsible for the severity and breadth of these nationwide outbreaks. This suggests that regulatory agencies ought to more closely scrutinize the microbiological quality of the operations of the major distributors. I believe that those efforts would greatly reduce the likelihood of future major outbreaks of food poisoning.

Until next time.
