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...

On several occasions while driving in upstate New York, I noticed an exit sign on the NY State Thruway for Coxsackie, NY. And, not surprisingly, I began to wonder whether or not the Coxsackie virus was named after this obscure upstate NY town.

I first learned about coxsackie viruses as a graduate student while taking a medical virology course at the University of Wisconsin taught by the late noble laureate Howard Temin. However, despite a thirty year friendship with Vincent Racaniello, a BioCrowd co-founder and virologist extraordinaire, I never asked him about the origin of the coxsackie virus name. Much to my surprise, he had recently taken a trip to upstate NY and noticed the Coxsackie NY exit sign while driving on the thruway. This prompted him to blog about the coxsackie virus isolation, its pathogenic properties and of course, the origin of its name!

Coxsackie NY and the virus named after it 

by Vincent Racaniello,PhD

Recently while driving north on the New York State Thruway I passed the exit for the town of Coxsackie, NY (population 8,884). I grabbed my camera and photographed the exit sign, and reminded myself to write about the virus named after this small town.

In the summer of 1947 there were several small outbreaks of poliomyelitis in upstate New York. Gilbert Dalldorf, the director of the Wadsworth Laboratory in Albany, NY, and his associate Grace M. Sickles investigated this outbreak. In particular they sought polioviruses that could replicate in mice. This search was motivated by the fact that research on poliovirus required the use of monkeys which were extremely expensive. Dalldorf had attended the Fourth International Congress for Microbiology in 1947 where he heard that very young mice – suckling mice – could readily be infected with Theiler’s virus.

Dalldorf and Sickles made fecal suspensions from two children suspected of having poliomyelitis, and inoculated these into adult and suckling mice. Only the suckling mice (1 – 7 days old) developed paralysis; animals more than one week old were resistant to infection. The damage responsible for limb paralysis was widespread lesions in skeletal muscles, not in the central nervous system as occurs with poliovirus. Further study revealed that the viruses could be distinguished serologically from poliovirus.

Not only had Dalldorf and Sickles identified the first members of a very large group of human viruses, but they also introduced and popularized a new and inexpensive animal into the virology laboratory – the suckling mouse. In 1949 Dalldorf suggested that the new viruses be called Coxsackie viruses, because the first recognized human cases were residents of that New York village. This unique name is of native North American origin.

Over ten years later the importance of this work was recognized by Dr. Max Finland of Boston City Hospital:

The isolation by Dalldorf and Sickles of viruses which produced paralysis with destructive lesions of muscle in sucking mice and hamsters, from the stools of two children with signs of paralytic poliomyelitis was an achievement that may rank in importance with Landsteiner and Popper’s production of human poliomyelitis in monkeys.

In subsequent years many different Coxsackie viruses were isolated that cause a variety of clinical syndromes. Today at least 30 serotypes of Coxsackie viruses are classified in the enterovirus genus of the Picornaviridae. The viruses are classified into groups A or B depending upon the pathological effect in suckling mice.

Not every locale is pleased to have a virus named after it. In May 1993, an outbreak of an unexplained pulmonary illness occurred in the southwestern United States, in an area shared by Arizona, New Mexico, Colorado and Utah called “The Four Corners.” Muerto Canyon was proposed as the name for the etiologic agent of the disease, because the virus was first isolated from a rodent near the canyon. However after residents objected, the name Sin nombre virus was given to the agent of hantavirus pulmonary syndrome.

Dalldorf G, & Sickles GM (1948). An Unidentified, Filtrable Agent Isolated From the Feces of Children With Paralysis. Science (New York, N.Y.), 108 (2794), 61-62 PMID: 17777513

As we all know, the H1NI pandemic has been raging on for close too 10 ten days now. Curiously, “Fear & The Flu: The New Age of Pandemics” is the title this week’s cover story in Newsweek magazine. From an informational standpoint point, “this may be too little, too late”—as the old saying goes. While the Internet has been around for over twenty years now, government agencies, most notably the US Food and Drug Administration (FDA) and the Centers for Disease Control (CDC) continue to rely almost exclusively on old media to communicate with the American public during infectious disease outbreaks. Apparently, the administrators who run these government agencies haven’t been listening closely enough to President Obama’s assertion that “we live in the digital age.”

Communications between the public and government health officials is vital when trying to manage and control infectious disease outbreaks. “Every single government agency as well as companies and non-profits need to be digitally literate and competent in a time of pandemic” asserts Eye on FDA blogger Mark Senak. For their performances in recent infectious disease outbreaks, Mark gives CDC an “A” for effort—although there is substantial room for improvement. FDA on the other hand didn’t fair as well. “The FDA is not nearly as sophisticated in terms of digital. Their only Twitter account is for food recalls.  And their YouTube channels are all confusing and unorganized. They have a long way to go.”

The Internet was originally designed as a digital tool to transmit and move large amounts of information from one place to another. That said, it is also a powerful communication vehicle that can be used to broadcast valuable, scientifically-accurate information during infectious disease outbreaks by leveraging social media tools like Twitter, Facebook and instant messaging. To that end, it’s time for public health agencies to recognize the power of digital media and craft communication plans that can be implemented in the next infectious disease outbreak.

Until next time...

A quick perusal of the media coverage of the swine flu outbreak of 2009 would lead many to conclude that this outbreak has the potential to rival or surpass the 1918 flu pandemic—widely regarded as the worst influenza outbreak in history. While the emergence of a new H1N1 swine flu variant is significant note worthy— and has possible public health implications— the unrelenting, often scientifically-inaccurate media coverage did little to quell the fear and anxiety of many Americans.  Once again, the media—rather than physicians, public health officials and influenza experts—“got out in front of the story” and managed to create enough panic, fear and anxiety, the likes of which haven't been seen since the 2003 SARS pandemic. It wasn't until last Friday, when the Wall Street Journal published an interview with Dr. Peter Palese—a leading scientific expert on influenza A infections— did a clearer picture emerge about the severity and public health implications of the current swine flu pandemic.

According to Dr. Palese, there are several reasons why people and public health officials ought to be optimistic about the current pandemic:

• In 1976 there was a an outbreak of an H1N1 swine virus in Fort Dix, New Jersey, which showed human to human transmission but did not go on to become a highly virulent pandemic strain
• The presently circulating swine virus is most likely not more virulent than the other seasonal strains we have experienced over the last several years
• The current swine virus lacks an important molecular signature (the protein PB1-F2) which was present in the 1918 virus and in the highly lethal H5N1 chicken viruses.  If this virulence marker is necessary for an influenza virus to become highly pathogenic in humans or in chickens, then the current swine virus doesn’t have what it takes to become a major killer
• Since people have been exposed to H1N1 viruses over many decades, we likely have some cross-reactive immunity against the swine H1N1 virus. While it may not be sufficient to prevent becoming ill, it may very well dampen the impact of the virus on mortality.  I would postulate that by virtue of this “herd immunity” even a 1918-like H1N1 virus could never have the horrific effect it had in the past.  The most likely outcome is that the current swine virus will become another (fourth) strain of regular seasonal influenza

The landscape of vaccines and anti-influenza drugs has dramatically improved over what it was just a few years ago. Based on what we know of the structure and sequence of the swine virus, these FDA-approved drugs and FDA-licensed vaccines (modified to include the swine strain) would be highly effective against this new virus.  Also, present technologies as well as manufacturing capacities will allow us to make sufficient quantities of a swine virus vaccine for the winter 2009-10 influenza season in the US.

In other words, there is reason for concern but no need to panic beyond typical public health precautions that are taken during “normal” influenza outbreaks.

Dr. Vincent Racaniello, a viral disease expert who writes the Virology Blog, reported that as of Monday there have been laboratory confirmed cases of H1N1 infections in 30 US states with a total of 226 cases and one death in Texas. Globally, 20 countries had reported 985 cases of infection. The highest numbers are in Mexico, with 590 cases and 25 deaths. While there have been 26 deaths to date, the severity of the infection appears to be waning and person-to-person transmission appears to be low.

Unfortunately, there has been some fallout from the news media’s oft times “over the top” coverage of the pandemic. Many US hospital emergency rooms (most notably in Texas and California) have been overwhelmed and overburdened by visits from people who think they may have swine flu. Also, while some schools and daycare center closures were warranted, others may not have been. Finally, and perhaps most important, it is becoming increasingly apparent that the lay public's understanding of infectious agents and the outbreaks that they cause is grossly deficient and must be improved. 

We live in a world where viral pandemics, food poisoning outbreaks and infections caused by multiple-antibiotic resistant bacteria are becoming commonplace. While vaccines, antivirals and antibiotics can afford some protection against many viral and bacterial disease, the best way to fight infectious diseases is to understand what causes them, how they are spread and what public health measures can be implemented to prevent or control their transmission. Until the world becomes better educated about infectious diseases, we will continue to be overly-dependent on the news media during future outbreaks and epidemics.

Until next time....

Do you lie awake a night overwhelmed by the possibility of another infectious disease outbreak? Well, if you want to get a good night’s sleep, I highly recommend that you take a look at a brief history of American epidemics that was published in this past Sunday’s New York Times. According to the article, history shows that the number of American epidemics has been relatively small. In fact, the author suggests that there were only nine major epidemics in the US since 1892. 

While there were several major outbreaks in the early to mid 1900s (Spanish flu, 1918; smallpox, 1947 and polio, 1952), the US has been relatively unscathed in recent years—with the possible exception of the HIV/AIDS epidemic and possibly the herpes and HPV epidemics. This is because of America’s outstanding infectious diseases surveillance networks, its comprehensive vaccination programs and modern medical and hospital infrastructures.

However, no matter how vigilant we are, there is no way to prevent infectious disease outbreaks unless the pathogens that cause the diseases are eradicated from the planet as was the case for the smallpox virus. That said, the best way to manage infectious disease epidemics is to be prepared for all contingencies.  In my opinion, the recent swine flu outbreak—this was its second appearance, the first taking place in 1976—was a practice run. And I think the world did “pretty, pretty good” as Larry David, my former NYC softball teammate and co-creator of Seinfeld would say!

Until next time...

According to a report on NPR’s All Things Considered program, the Obama Administration has nominated Margaret Hamburg, MD to head the US Food and Drug Administration. Dr. Hamburg is a former health commissioner in New York City who has worked on issues surrounding infectious diseases and bioterrorism. In New York, she instituted a needle-exchange program to help prevent the spread of HIV. She also set up a program, in which health workers went to tuberculosis patients’ homes to help them manage their drug regimens.

A Harvard Med School graduate, Dr. Hamburg was an assistant secretary of health and human services during the Clinton administration and now works at the Nuclear Threat Initiative, which tries to cut the threat from nuclear, chemical, and biological weapons. She opposes abstinence-based sex education in public schools and has been a critic of the marketing practices of the pharmaceutical industry. Further, Dr. Hamburg is a leading advocate for changes in the nation’s public health policies and infrastructure, from local health departments to the highest levels of government. Finally, after eight years of mismanagement and poor leadership, the agency has somebody at the helm with intelligence, experience and is an advocate for change. 

Kudos to Team Obama!

Until next time...

Vincent Racaniello, my partner at BioCrowd, and I were chatting the other day about how cool it would be to develop a web-based map that was able to track infectious diseases outbreaks in real time. After a spirited chat, we both thought that we were on to something REALLY big. And, as is frequently the case, somebody else also had the very same idea.

For those infectious disease aficionados out there, you must check out the Health Map: A Global Disease Alert Map. The map was developed by Clark Freifeld and John Brownstein and is based on an algorithm that is beyond my comprehension. It is not as robust as the map that Vincent and I envisioned, but it is pretty cool and it works very nicely.

Until next time…

No matter what you may think of Google, you gotta love the brilliance and innovative moxy of the guys who run that company. In today’s New York Times, there was a story about a new web tool called Google Flu Trends. This tool is being evaluated as a new early warning system for fast-spreading flu outbreaks in the US.

Tests of Google Flu Trends, suggest that it may be able to detect regional outbreaks of the flu a week to 10 days before they are reported by the Centers for Disease Control and Prevention (CDC). It works by tracking and quantifying number of Americans who enter search phrases like “flu symptoms” into Google and other search engines. By analyzing these searches as they come in, Google Flu Trends creates graphs and maps of the country that show where the flu is spreading.  For example, in early February the CDC reported that the flu cases had recently spiked in the Mid-Atlantic States. But Google says its search data showed a spike in queries about flu symptoms two weeks before the CDC report was released.

According to public health experts “The CDC reports are slower because they rely on data collected and compiled from thousands of health care providers, labs and other sources. The Google data could help accelerate the response of doctors, hospitals and public health officials to a nasty flu season, reducing the spread of the disease and, potentially, saving lives.” Researchers have long contended that information published on the Web amounts to a form of “collective intelligence” that can be used to spot trends and make predictions.

Google Flu Trends appears to be the first public project that uses the powerful database of a search engine to track a disease. This could be the beginning of a new trend in epidemiology. Google hopes to publish the results of its study in Nature.

Until next time…

As the old saying goes, nobody is indispensable.  On the heels of Friday's report about US unemployment reaching 6.1 per cent, I learned that my contract medical writing position would be ending 4 months sooner than expected.  I worked at the company for 1.5 years and was excepting to finish out a two-year stint.

Of course, given the precarious financial state of the pharmaceutical industry, I had been looking and was able to find several opportunities that may translate into freelance gigs or possible employment. That said, if anybody out there is looking for an experienced medical/science/promotional writer, please feel free to contact me by sending a comment to this post or via e-mail: cmintz@bioinsights.com.

I hope that your luck is better than mine!!!!!

Until next time....

Good Luck and Good Job Hunting (I will be looking too)!!!!!!!!!

Metals like copper and silver have long been known to possess antibacterial properties. I learned this as an undergraduate microbiology major circa 1972. That said, I didn’t know whether to laugh or cry when I read an article in today’s NY Times entitled "Regulators Stamp Copper as a Germ Killer". According to the article, the Copper Development Association (CDA), a NY-based trade group for copper companies, announced that federal regulators at the US Environmental Protection Agency (EPA) approved its application to market copper, bronze and brass-containing products as antibacterials that are effective enough to protect against bacterial infection. Apparently, what made this newsworthy is that this is the first time that EPA has allowed health claims to be attached to a solid antimicrobial material (rather than an aerosol or liquid disinfectant). For those of you who may not know, EPA (not FDA) regulates antimicrobial agents like disinfectants and air fresheners that are not directly applied to the human body.

Not surprisingly, there are many consumer products already on the market which are impregnated with silver and some other antimicrobial substances that claim to reduce the risk of infection.  Some of the more creative and pricey ones include silver-coated computer keyboards and mice manufactured by Iogear. However, none of the companies that manufacture these products can legally claim that the impregnated metals in them kill bacteria or provide a health benefit because they never thought to submit data to  EPA regulators to substantiate these claims. This is marked contrast with the CDA which smartly and painstakingly performed “clinical studies” for the past 4 years with copper and its alloys (mostly door knobs) to gain regulatory approval to claim that these metals have bona fide antibacterial properties. According to a CDA spokesperson, additional “clinical trials are underway to test how copper bed rails, arm rests and other hospital fixtures can reduce the numbers of bacteria in hospitals.”

Don’t get me wrong–you gotta love the creativity of the CDA for developing an innovative business strategy to help maintain the price of copper and bolster the sales of copper-based products. As you may know, the advent of fiber optics and silicon chips has been steadily pushing the price of copper down for the past few years–something that the CDA is keenly aware of.  Unfortunately, in contrast with CDA’s new vision, I believe that the only way to effectively reduce the high bacterial loads in our hospitals is through vigorous enforcement of hospital sanitation and hygiene programs, regular screening of hospital personnel and routine environmental monitoring.  Based on over 30 of experience with food borne and nosocomial bacterial diseases, I firmly believe that improperly sterilized equipment and instruments and people who are either unsuspecting carriers or fail to maintain good sanitation and hygiene practices are the main causes of bacterial contamination and transmission in hospital settings. I don’t think that inanimate metal objects (which have long been known to have inherent antimicrobial properties) contribute to the high levels of bacteria that are commonly found in today’s hospitals. Nor do I think that replacing existing hospital fixtures with copper, brass or bronze ones will do much to reduce bacteria levels in most hospitals.  Nice try CDA–but no cigar this time (at least not from me)!

Until next time….
