UFC Crackdown on Streaming Piracy?
MMAPayout.com has posted before on the UFC”s efforts to stem the tide of piracy of their PPV broadcasts. Up to this point these efforts have mainly been through going after bars and restaurants that illegally show their cards. This campaign is done mainly through the efforts of Joe Hand Promotions, who handles the bar and restaurant PPV business for the UFC.
The UFC may be going a step further into these efforts, judging from information put out by BayTSP, which provides online copyright monitoring, enforcement, measurement and monetization services for the entertainment industry, software and videogame makers and the publishing industry. The company recently announced:
One global sports franchise and two of the largest pay-per-view event promoters in the world have signed with BayTSP to protect and monetize broadcasts valued at more than $5 billion annually, the company announced today.
The logical companies to attach to this information would be the UFC and WWE for the PPV event promoters and Manchester United Football Club for the global sports franchise. The crackdown has already been cited by some as a possible reason behind the precipitous drop in traffic at the streaming site Justin.tv.
Nate Quarry talks UFC 97 & Video Games!
PDG: UFC 97 in Montréal, Canada is a pretty stacked card; what fights are you looking forward to seeing that night?
Quarry: Any time that you get a chance to fight on a card with Chuck Liddell and Anderson Silva, it is a real treat. I have been a fan of Chuck's for a long time and we are also friends. So being able to be there and to say I fought on the same card as Chuck Liddell is a real honor. That is something that I will always remember.
MacDonald Inks Round 5 Deal
The Fight Network has the info on Jason MacDonald signing a figurine deal with Round 5:
Pavelich Sports Entertainment is pleased to announce that Jason “The Athlete” MacDonald has signed a deal with toy manufacturer Round 5 MMA to create his very own action figure.
MacDonald, a native of Edmonton, Alberta, will now join a very exclusive and elite group of fighters that have all collaborated with Round 5 to produce some of the most detailed and unique MMA action figures in the world.
“Since we are based in Ontario, I am particularly excited that Jason MacDonald is the first Canadian to sign with Round 5,” said Damon Lau, Round 5 President and Co-Founder. “He is one of the most successful and popular MMA stars in the country and enjoys a strong following across North America.”
It is interesting that Round 5 is now reaching into the mid-tier level with their signings. The initial signings have been high profile: Couture, Matt Hughes, Wanderlei, Rampage, etc. When looking at the mid tier fighters, Round 5 may look to hit those fighters that have some degree of tenure with the UFC, giving them name recognition if not superstar status. Other factors like being a regional draw (MacDonald’s Canadian roots) may also be taken into consideration.
Steinbeiss talks about cancelled UFN 18 Fight
PDG: How did you find out that your fight with Ryan Jensen was canceled?
Steinbeiss: We were about 30 seconds away from stepping up onto the stage for weigh-ins and right then they pulled us aside and said that the fight wasn't going to go on because of the Adderall thing.
PDG: That had to be pretty disappointing considering all the work that you put in to prepare yourself for that fight.
Steinbeiss: Most people have no idea; I made the weight and was ready to go through the weigh-ins and then pound some Pedialyte. 10 weeks of hard training and then the day before the fight you find out it is canceled. It certainly took the wind out of my sails.
Mino and Stallone together?
The news broke today in the ‘O Globo,’ newspaper that Sylvester Stallone will be inviting Rodrigo Minotauro to participate in a moving being shot in Rio de Janeiro.
As discerned by GRACIEMAG.com, contact was made through Rodrigo’s adviser, Fernando Flores.
Mino, who is in Miami, arrives in Rio tomorrow, when he may meet with the star of “Rambo” and “Rocky.” Stallone’s team also expressed interest in meeting other well-known fighters, like Lyoto Machida and Rogerio Minotouro.
Actor, producer, director and screenplay writer of “The Mercenaries,” Stallone, 62, has already called upon Randy Couture for the full-length action movie, as reported by GRACIEMAG.com last December 18th. Yesterday, at a press conference in Rio, the Hollywood star said he is an MMA fan and spoke about the city.
He justified his choice in having Randy Couture, 45, in the film. Couture has already appeared in “Redbelt,” the 2008 movie by David Mamet.
“Couture will participate in this movie because he looks like a gladiator,” said Stallone. “I like fights and even know some Brazilian fighters; who knows maybe some of them will be in the film.”
“I came to shoot in Rio because the script called for a tropical setting and I found the city ideal for it. The movie shows mercenaries for a cause, and doesn’t intend to harm Rio’s image,” stated the debuting director. Although Stallone tend to surprise, the story of “The Expendables,” with Forest Whitaker, Gisele Itie and a large cast, isn’t too original at the outset: it is the story of a group trying to overthrow a Latin American dictator.
Lashley To Appear At XFC 8 After All
Although rumors of him fighting on the card turned out to be false, Bobby Lashley will still appear at the upcoming XFC 8 event in Tennessee, but only to present the new XFC Title belt to the winner of the Jarrod Card vs. Bruce Connors featherweight bout which will now headline the show.
Some Managers, Agents Lose Backstage Pass
Managers and agents are fast becoming an endangered species backstage at UFC and WEC events.
Zuffa, the company that owns and operates both promotions, has notified select fighter representatives that they will no longer receive credentials from the promotion to sit with their clients backstage on fight night.
The reasoning behind the UFC’s decision varies according to the source. Some say the move is yet another strike in a campaign to separate fighters from their business representatives. Others say Zuffa is making a reasonable attempt to control unnecessary backstage traffic and lighten overcrowded dressing rooms of freeloaders.
The latter explanation loses traction, however, when the promotion has not enacted a blanket policy across the board, which brings into question if the move is more personal than procedural.
Of five separate fighter representatives and their firms that spoke to Sherdog.com, two said they were told that credentials would no longer be doled out to them shortly after UFC 94 on Jan. 31. These firms were also denied backstage access in person at UFC Fight Night 17, UFC 95 and UFC 96, as well as WEC 39, which took place March 1 in Corpus Christi, Texas.
Both reps said Zuffa would give no reason for the change in policy when asked over the phone and in person.
“You don’t ask questions of them. You know how that goes,” said one manager, who, like multiple fighter representatives interviewed, would only speak on the condition of anonymity for fear of repercussions.
Zuffa’s public relations department did not respond to an e-mail requesting comment on the promotion’s sudden shift in policy after eight years.
Outraged managers and agents said the silent treatment speaks to a greater issue that Zuffa is trying to keep hidden behind closed locker room doors.
“They’re divisively trying to split management and fighters,” said one representative. “They’re trying to de-power the managers and agents to create a wedge between them. They give locker room bonuses and say, ‘This is from Dana [White] and the UFC -- nobody else.’ They’re telling fighters they can go directly to them. They’re telling fighters they’ll be doing sponsorships themselves in the near future that will put the managers and agents out of business. They’re trying to minimize the managers’ and agents’ role in the fighter’s life so they can better control salaries.”
This Day In MMA History: March 27
March 27 is remembered, by MMA fans, as a day that will forever live in infamy. It marked the day Zuffa made a purchase that was to make UFC the MMA megapower of the world. But it ultimately marked the beginning of the journey that, a few months later, ended with the death of the PRIDE Fighting Championships.
Another Husband-Wife MMA Couple Emerging
Fighting, both as a fighter and spectator/supporter, has been a big part of Emily Fisher's life. Between operating a gym run by and training with her husband, UFC fighter Spencer Fisher, Emily Fisher is part of a growing subset of MMA fighters, those who don't necessarily fight for the money or the fame but the self-respect and pleasure of accomplishment. The days spent preparing in the gym translate into confidence in other aspects of life, and the exhilaration of a fight simply can't be matched in day jobs or other errand tasks. Emily, 3-1 and preparing for her 5th fight in May, is one of a growing breed of part-time fighters who accept the business of MMA as part of their lives.
Sylvia Vs. Mercer Boxing Match Now Off For Now
The planned main event boxing fight between boxing legend Ray Mercer and former UFC Heavyweight Champion Tim Sylvia at Adrenaline MMA 3 on May 30 is now off. The New Jersey State Athletic Control Board will not sanction the fight. This means Adrenaline 3 will be an all-MMA event. The promotion is looking for a replacement main event, and Adrenaline may try again elsewhere in June.
The Man That Was ‘Mask’
Charles “Mask” Lewis Jr. had all the faith in the world.
It takes nothing less to be the first of your kind, to see opportunity and potential in places where others simply do not. It takes even more to act upon that vision, to put yourself out on a limb in the face of ridicule and failure.
Lewis had faith in the sport of mixed martial arts. Through his Tapout clothing line, he championed it without a hint of hesitation to every stranger, friend, and foe alike.
Charles Lewis was one of the good guys. And that’s why his death in a horrific car crash during the early morning hours of March 11 hit the fight community so hard.
As is the case with those we cherish most, Lewis was gone too suddenly. He was on his way home from the gym with his girlfriend Lacey at 1 a.m., the only time he could fit working out into a hectic schedule. Lewis took pride in his deceiving physique, and many questioned he was really 45 years old, even after officials confirmed it.
That night, Lewis and Lacey had decided to drive by a condominium apartment they had been looking into purchasing over the next few days. It is believed Lewis’ fire-engine red Ferrari occupied the middle lane when Jeffery Kirby and his companion came up along the left side in a white 1977 Porsche. At the scene, black skid marks snake up onto the median’s curb right as the road bends slightly, then drag for 500 or more feet across the three lanes. They indicate Kirby’s car bounced off the road’s island divider before t-boning into Lewis’ vehicle’s backend, sending the Ferrari into a 180-degree spin. The car traveled backwards before the driver’s side wailed directly into a cement light pole, slicing it into two parts.
It was the first time in a few months that Lewis had had the opportunity to enjoy the luxury ride he’d purchased over a year ago. The car had slept at a friend’s showroom until Lewis had been asked to bring it to a photo shoot that day for Dub magazine. High speeds didn’t seem unfathomable under the circumstances, though friends said they couldn’t see Lewis engaging in a dangerous street race for superiority. Lewis didn’t know Kirby, nor was Lewis believed to be drinking at the time. Lewis never touched alcohol, as many will attest, including his best friend and business partner Dan “Punk Ass” Caldwell.
Lewis and Caldwell met in 1992 as sheriffs for San Bernardino County in southern Calif. Both trained in boxing and kickboxing, but soon found a mutual love in Brazilian jiu-jitsu and the early UFC events.
The name Tapout was born from the license plate on Lewis’ car. It was a way for Lewis to demonstrate his unadulterated love for the art and he displayed it around town like his badge of honor.
“Especially then, when you would ride down the freeway with ‘Tapout’ on your license plate, people would come up to you and look inside and give you a thumb’s up. That’s how you knew another jiu-jitsu guy,” said Caldwell.
When a license plate wasn’t enough, Lewis went to Caldwell with an idea for a T-shirt
Dana White's UFC 96 Vlog Ep. 4
edit: kind of funny to see scott "hands of steel" wearing an affliction shirt in front of dana. I saw him at day of reckoning, maybe he got out of his elitexc contract to sign with them ?
Ken Shamrock vs Bobby Lashley CONFIRMED!
Sources close to Bloody Elbow can exclusively confirm that the heretofore unnamed opponent of former WWE superstar Bobby Lashley set to square off at Roy Jones Jr.'s mixed boxing and MMA event known as "March Badness" is none other than Ken Shamrock.
Multi-drug resistent staph (and other bacteria) on the rise
This is a message to all those fighers and dojo owners that don't think it's important to keep their mats, bodies and equipment clean.
It's a long read, but I tried to highlight the key points so at least try to read them. The other text is for your further information.
Maybe it was just a bad month--an unfortunate statistical fluctuation. Maybe not. As Vance Fowler, an infectious-disease specialist at Duke University Medical Center in Durham, North Carolina, tells it, the first case appeared in early spring 2008: a 13-yearold girl whose bout with the flu evolved into a life-and-death struggle, still ongoing, with necrotizing pneumonia and a particularly pernicious strain of bacteria known as methicillin-resistant Staphylococcus aureus (MRSA). Should the girl survive, her life will be "forever changed," says Fowler, from pulmonary disease caused by the death of the lung tissue. The next case, a week or so later, was a research technician from Fowler's laboratory, admitted to the hospital with a facial abscess that showed no signs of healing. Again, MRSA was the cause. A week or so after that, the victims were a husband and wife. "Both were admitted with life-threatening acute MRSA infections out of nowhere," he says. "Multiple surgeries. Life- and limb-threatening infections." Neither one worked in a hospital or a long-term care facility, the kind of environments in which such bacteria might commonly be found. Nor had they visited one recently. So how did they get it? "Bad luck, bad genes, a bad bug, or all three," says Fowler.
The last decade has seen the inexorable proliferation of a host of antibiotic-resistant bacteria, or bad bugs, not just MRSA but other insidious players as well, including Acinetobacter baumannii, Enterococcus faecium, Klebsiella pneumoniae, Pseudomonas aeruginosa, and Enterobacter species. The problem was predictable--"resistance happens," as Karen Bush, an anti-infectives researcher at Johnson and Johnson (J&J) in Raritan, New Jersey, puts it--but that doesn't make it any easier to deal with. In 2002, the U.S. Centers for Disease Control and Prevention (CDC) estimated that at least 90,000 deaths a year in the United States could be attributed to bacterial infections, more than half caused by bugs resistant to at least one commonly used antibiotic. Last October, CDC reported in the Journal of the American Medical Association that the number of serious infections caused by MRSA alone was close to 100,000 a year, with almost 19,000 related fatalities--a number, an accompanying editorial observed, that is larger than the U.S. death toll attributed to HIV/AIDS in the same year.
So far these outbreaks have been concentrated in hospitals, where the environment is particularly conducive to the acquisition and spread of drug-resistant bugs. But the big worry, for Fowler and others, is that they will spread to the wider community--a nightmare scenario, he says. MRSA is particularly worrisome, but so is another class of bacteria, called Gram-negative bacteria, that are even tougher to defeat. These include A. baumannii, which has plagued injured soldiers returning from Iraq. For these bacteria, the pipeline of new antibiotics is verging on empty. "What do you do when you're faced with an infection, with a very sick patient, and you get a lab report back and every single drug is listed as resistant?" asks Fred Tenover of CDC. "This is a major blooming public health crisis."
Right bug, wrong place
One of the many misconceptions about bacterial infections is that the bugs involved are not native to the human body or are particularly pernicious to begin with. Virtually all bacteria are capable of causing serious infections, at least in immunocompromised patients, although most do not. In hospitalized patients, many infections arise from the patient's own bacterial flora, flourishing where they're not supposed to be. Pneumonia, for instance, can be caused when bacteria from the mouth are aspirated to the lungs. Just as Escherichia coli is a normal inhabitant of the gut, S. aureus colonizes the skin and mucosal surfaces in the nose in 30% of the population. When it sets up shop somewhere else, S. aureus can cause a host of infections, including skin abscesses, necrotizing pneumonia, joint infections, and heart valve infections known as endocarditis. Similarly, S. epidermidis normally colonizes the human skin, but when it gets into the bloodstream, it can cause sepsis and endocarditis, as well as infections involving prosthetic devices such as pacemakers and artificial joints. The risk of acquiring one of these serious infections is highest in hospitals [or in a combat sport training facility] and health-care facilities simply because these environments offer the greatest opportunities for bacteria to enter the bloodstream or infect open wounds.
Treating a bacterial infection with antibiotics is the obvious first step. But in the 65 years since the first widespread use of penicillin during World War II, infectious-disease specialists have been treated to an ongoing tutorial in the many ways bacteria can acquire and spread resistance to these drugs. Unlike tuberculosis and other bacteria, in which antibiotic therapy simply selects for rare resistance-bestowing mutants, the bacterial strains that are so insidious in hospitals employ far more diverse techniques, says Louis Rice of Case Western Reserve University and the Louis Stokes Cleveland VA Medical Center in Ohio. S. aureus and Enterococcus, for instance, can acquire resistance by exchanging entire genes or multiple genes with other bacteria, either through plasmids--loops of DNA that are independent of the bacterial chromosomal DNA--or so-called gene cassettes or transposable elements that can be inserted directly into the chromosomal DNA.
Penicillin and all penicillin-like antibiotics are ringlike molecular structures, known technically as -lactams. They work by attacking a particular cell wall enzyme in the bacteria. The first strains of penicillin-resistant S. aureus, which arose within a few years of penicillin's introduction, were strains that have a survival advantage because they naturally produce an enzyme--penicillinase, one of a class of enzymes known as -lactamases--that destroys the ring structure of penicillin. Within a decade, the effectiveness of penicillin against hospital-acquired staph infections was "virtually annulled," says microbiologist Alexander Tomasz of Rockefeller University in New York City, by "plasmid epidemics" that then spread the penicillinase gene through the entire species of S. aureus.
The pharmaceutical industry responded in the 1950s with a host of semisynthetic penicillins designed to be resistant to penicillinases. Methicillin, introduced in 1959, was believed to be the most effective. As Graham Ayliffe, a veteran hospital infection expert at the University of Birmingham in the U.K., recalled, "this was [supposed to be] the end of the resistant staphylococcus." Within 2 years, however, hospitals in Europe were identifying strains of S. aureus that were resistant to methicillin: the first MRSA strains.
Researchers later realized that these strains had taken a different route to acquiring resistance. Rather than generating new or different -lactamases, which could attack the antibiotic directly, they had acquired a new gene entirely, called mecA, that coded for a variant of the antibiotic's target: the penicillin-binding protein. When the antibiotics attack the original penicillin-binding protein, explains Tomasz, this "surrogate" binding protein "takes over the task of cell wall synthesis" and works to keep the antibiotic at bay. The mecA gene itself, says Tomasz, appears to derive from a common bacterium on the skin of domestic and wild animals known as S. sciuri. How S. aureus came to acquire the gene is a mystery, but since it did, it passes it on by exchanging entire gene cassettes with the mecA gene on them.
Through the 1970s and 1980s, MRSA remained little more than a nuisance bug, although occasional hospital outbreaks would have to be reined in with strict isolation and control programs. In the mid-1980s, typically only 1% to 5% of all S. aureus isolates were methicillin-resistant, says Henry Chambers, an infectious-disease specialist at the University of California, San Francisco. Around that time, S. aureus began to acquire genes that confer resistance to other common antibiotics, apparently from methicillin-resistant S. epidermidis and carried on the same mobile cassettes as mecA. The result was a bug that was both far more difficult to treat and, as Chambers says, "pretty adaptive to surviving in hospitals." Today, 60% to 70% of all S. aureus strains found in hospitals are multidrug-resistant MRSA.
Worries intensified when MRSA appeared a decade ago as a community-acquired infection rather than one exclusive to health-care settings. In 1999, CDC reported on four deaths in Minnesota and North Dakota, all children, all caused by MRSA infections that could not be traced back to hospitalizations by either the patients or family members. Somehow the mecA gene had emerged in S. aureus strains outside hospitals or health-care facilities. "This was a real biological success story," says CDC's Tenover. "And it all happened off our radar screens." MRSA isolates then began to appear in a range of unexpected community settings: children in day-care centers, army recruits, athletes in contact sports, native Americans living on reservations, prison populations, intravenous drug users, and among men who have sex with men.
The possibility that these MRSA strains were simply hospital strains that had migrated out into the community was refuted by analysis of the gene cassettes carrying the resistance. In hospital strains, these cassettes are relatively large and carry multiple resistance-bestowing genes, explains Tomasz. The "oddball" cassettes carrying the mecA gene in the early community-acquired isolates were small and contained only the one gene. In the last few years, however, MRSA strains in the community have begun to acquire multidrug resistance, suggesting that they've been intermingling with the hospital strains.
A half-dozen community-acquired MRSA clones have now spread around the world as their prevalence in the community has continued to increase; in San Francisco, for instance, up to 50% of all S. aureus isolates outside health-care settings are now methicillin-resistant. "These methicillin-resistant strains seem to be replacing the susceptible strains of S. aureus in the general population," says Mark Enright, an infectious-disease specialist at Imperial College London (ICL), "which means people are carrying strains of MRSA in their nose in the community. Now when they get infections, ones that were formerly treatable are going to be replaced with difficult-to-treat infections."
The public health anxiety increased still further in 2002 with the detection of isolates of MRSA that were fully resistant to the antibiotic vancomycin, traditionally considered the last resort for treating resistant staphylococcal infections. These S. aureus isolates seem to have acquired a gene for vancomycin resistance--vanA--from enterococci, and specifically E. faecalis, which are part of the natural flora of the intestinal tract and can cause serious infections in hospitalized patients. When the enterococci developed resistance to common antibiotics in the 1980s, physicians had responded by using vancomycin to treat them. Vancomycin-resistant Enterococcus (VRE) was first reported in 1986, and the vanA gene soon spread throughout the species. Because enterococci readily exchange genetic information with other bacterial species, says Tenover, he and other experts assumed that it would soon pass vanA and vancomycin resistance to MRSA. "Everybody was waiting for the shoe to drop," says Tenover. In 2002 it did, when the Michigan Department of Community Health reported the first isolate of MRSA that had vanA-mediated resistance to vancomycin. The patient was a 40-year-old diabetic who had recently been given an extended course of vancomycin for a foot ulcer.
Fortunately, vancomycin-resistant MRSA--now known as VRSA--has not developed into the nightmare researchers feared. Only nine isolates have been detected worldwide in 6 years, seven from the same region in Michigan, which suggests that S. aureus, unlike Enterococcus, loses the ability to compete in the broader environment when it takes on the vanA gene. That only one of these infections was life-threatening suggests that the vancomycin-resistant bug also loses its virulence.
A paltry pipeline
Although MRSA and other Gram-positive bacteria remain a major threat, a half-dozen new antibiotics have either just been approved or are in the pipeline that should work well against them--at least until the bugs evolve more resistance. This is not the case, however, for Gram-negative bacteria, such as P. aeruginosa, A. baumannii, and K. pneumoniae. These bacteria have both an inner and outer cell membrane, as opposed to the single cell membrane of Gram-positive bugs like MRSA. (The name comes from how these bacteria stain on a Gram stain test.) The pipeline for antibiotics against Gram-negative bacteria, says Bush of J&J, is limited to development programs in a few small companies; only one drug has made it through phase I clinical trials.
Prompted by the emergence of MRSA and VRE in the late 1980s, pharmaceutical companies focused their attention on Gram-positive bugs. Meanwhile, many Gram-negative bugs became resistant to virtually every known antibiotic, or at least every antibiotic that isn't toxic. "These organisms may well start to spread into the community," says Tenover, "and then we really will be in trouble. We have drugs to fall back on for Staphylococcus. But when you say, 'Where's the next anti-Pseudomonas drug?' I have to scratch my head."
One reason for the dearth of drug candidates is that Gram-negative bacteria are simply harder to kill. First, they have the extra cell membrane the drug has to penetrate. Then they have other defense mechanisms that Gram-positives lack, such as the ability to activate pumps or close down protein channels in the membranes that let these antibiotics in. "They can have three or four mechanisms working at once," says Case Western's Rice. "Even if you develop a new drug entirely, these bacteria may be just as likely to be resistant to new drugs as old ones. It's just really hard."
The problem has been exacerbated by the gradual exodus of pharmaceutical companies from antibiotic development--a trend that began in the 1980s and has accelerated since 2000, in large part because the market is iffy and the chances of success are slim. Of the 15 major pharmaceutical companies that once had flourishing antibiotic discovery programs, eight have left the field entirely, and two others have reduced their efforts significantly. That leaves only five--GlaxoSmithKline, Novartis, AstraZeneca, Merck, and Pfizer--that still have antibiotic discovery efforts commensurate with the size of the problem.
Even though the market for antibiotics is in the neighborhood of $25 billion a year, says Steve Projan, vice president of biological technologies at Wyeth Research in Cambridge, Massachusetts, other drugs, such as antidepressants or antihypertensives, offer a greater bang for the buck because they are often taken for years or decades rather than just a 7-to 14-day course. Resistance only compounds the problem: A drug that takes a decade to develop might be useful clinically for only a handful of years.
What's more, the better the antibiotic, the less health experts want to see it used to avoid the development of resistance. "It's probably the only area of medicine where a drug company can invest all this money to develop a drug, come up with a good one, and then the so-called thought leaders in the field, like myself, will tell people not to use it," says Rice. "We say it's such a good drug that we should save it."
As a result, virtually all the new antibiotics and all those in the pipeline for Grampositive bacteria are second-generation drugs, that is, incremental improvements on existing classes. The one conspicuous exception--daptomycin, developed for S. aureus by the late Frank Tally at Cubist in Lexington, Massachusetts--was first identified 20 years ago by Eli Lilly and Co. and then shelved because it had toxicity problems at high doses.
To the surprise of many, the recent sequencing of more than 650 bacterial genomes has been a "dismal failure" when it comes to drug development, says ICL's Enright. Although genome sequences were expected to yield a "treasure trove of new targets for entirely new classes of antibiotics," as David Pompliano and colleagues at GlaxoSmithKline in Collegeville, Pennsylvania, recently wrote, this simply hasn't panned out. At GlaxoSmithKline, Pompliano and his colleagues spent 7 years and more than $70 million evaluating more than 300 "canonical" bacterial genes that they thought were essential to the viability of the bacteria. The result was just five leads, a success rate, they estimated, that was four-to fivefold lower than for other areas of therapeutics.
Genomics is simply not a good paradigm for discovering new antibiotics, suggests Projan. The genetic approach assumes that a candidate drug can knock out a single gene in the bacterium to render it unfit for survival. But the drugs don't knock out a gene's activity entirely, he says; instead they modulate activity. "As we found out in oncology," says Projan, "sometimes leaving even 5% activity is enough for the tumor to grow. The same thing is true for bacteria." Projan and others suggest that the only route to a new antibiotic--short of pure luck--will be through more fundamental research on the basic biology of the bacteria.
Barring the discovery of miracle antibiotics to which bacteria cannot evolve resistance--a "laughable" notion, says one expert--the only foreseeable route to curbing antibiotic resistance will be to rein in the use of antibiotics. One obvious way is to lower the risk of acquiring resistant bugs in the hospital. Countries that have mandated rigorous infection control in hospitals, such as Denmark, the Netherlands, and Finland, have been able to keep MRSA infection rates low. These infection-control procedures, however, go far beyond physicians and nurses wearing gloves and protective masks and washing their hands before and after patient contacts., essential as those are. These nations employ a technique known as "active detection and isolation," or "search and destroy," as it's called in the Netherlands. Patients considered at high risk of carrying MRSA and other antibiotic-resistant bugs are cultured when they're admitted to the hospital, and periodic cultures are taken of all patients, particularly those in high-risk wards. The greater the prevalence of pathogens and risk factors, the more frequent this surveillance. Patients who are infected or are carriers are isolated. Health-care workers who are colonized with resistant bacteria can be "decolonized," using skin washes and nasal ointments
Whether U.S. hospitals should be required to implement active detection and isolation is a long-running controversy. Some specialists--led by University of Virginia epidemiologist Barry Farr, an expert on controlling VRE and MRSA--have argued that it's the only proven method to control hospital MRSA infections. Others have questioned the technique's cost-effectiveness and viability, particularly when rates of MRSA in the community are beginning to rival those in many hospitals.
Vaccines against antibiotic-resistant bacteria would also go a long way to reining in resistance, but only one such vaccine candidate, against S. aureus, has ever made it through phase III clinical trials: StaphVAX, licensed by Nabi Biopharmaceuticals. Although patients who received the vaccine had significantly lower rates of S. aureus infections at 40 weeks compared to controls, this apparent protection was lost at 54 weeks. A follow-up trial also failed to demonstrate efficacy. Several more vaccines are in development, including a new-generation StaphVAX. Even temporary protection could be useful, argue some experts, either for health-care workers, who could be vaccinated regularly, or for patients who are about to be hospitalized to undergo a procedure.
Ultimately, physicians will have to be persuaded to reduce their use of antibiotics, although that will be a hard sell. One step, for instance, would be to persuade physicians outside hospitals to treat only those patients who are truly infected. A 2001 study from the University of Colorado Health Sciences Center estimated that 55% of all antibiotics prescribed in the United States for upper respiratory infections were unnecessary. This is what Rice describes as the "get-a-little-sniffle-get-a-little-Levaquin" problem. "The patients want it," he says, and "the doctor wants to get the patient out of the office, and the quickest way to do it is to write a prescription." But the societal problem of antibiotic resistance should outweigh whatever personal peace of mind comes from the indiscriminate use of antibiotics, says Tenover (see sidebar on p. 360).
Similarly, many times physicians prescribe combination "broad-spectrum" antibiotics when a single "narrow-spectrum" antibiotic would do the trick. Understandably, says Rice, physicians are unwilling to wait to treat serious infections until the bug is cultured and they learn to which antibiotics it's still susceptible. But once the crisis is over, usually 1 to 3 days after starting therapy, physicians could switch their patients to the appropriate narrow-spectrum antibiotic.
What the field desperately needs, these experts say, are randomized, controlled trials to establish how long antibiotic therapy should be prescribed for different infections. The data are scarce, and misconceptions abound. The ubiquitous advice in the field--from physicians, patients, and even CDC--is that patients should continue the full course of antibiotics even after they feel better. Because antibiotics tend to have few side effects, physicians consider a longer course to be a no-lose proposition.
But from the perspective of preventing antibiotic resistance, says Rice, "this is totally wrong-headed." In patients with healthy immune systems, he explains, most antibiotics merely stun the bacteria sufficiently to make it easier for the host immune system to do its job. "You can take tetracycline until the cows come home," Rice says, and "all it does is stop most bacteria from growing. It doesn't kill them." Extending the course of the antibiotics unnecessarily increases the likelihood that the patient's normal flora will be inhibited to the point that bacteria resistant to the antibiotic will fill the void.
The few existing studies on the necessary length of therapy have suggested that it is often surprisingly short. Urinary tract infections in young women can be treated with 1-to 3-day courses of antibiotics. The Infectious Diseases Society of America recommends a 3-day treatment for traveler's diarrhea, while acknowledging that 1 day appears to be equally effective. Studies from the 1940s suggested that the "vast majority" of patients with pneumonia get better after 2 or 3 days, says Rice: "Somewhere along the line, that morphed into 7 days, 10 days, 21 days, with no real reason other than making the doctor more comfortable." In May, the U.S. National Institute of Allergy and Infectious Diseases responded to the expert demand and put out a request for proposals for clinical studies that would determine the optimal use of antibiotics, including the optimal duration of therapy. "I think most physicians would respond to compelling data from a well-done trial," says Rice.
One beneficial side effect to curbing antibiotic use is that it may serve to rehabilitate those antibiotics that have lost their effectiveness. "Many of these were wonderful new drugs just 20 years ago, able to treat a wide variety of bugs, both inside and outside the hospital," says Rice. "Now we're at a point where some of them are next to useless, because they've been used for everything."
South Carolina Close To Lifting MMA Ban
South Carolina may soon join the ranks of states that allow MMA in their state. A bill to lift the state's ban unanimously passed the state House yesterday and now heads for the state Senate, where easy passage is expected. This would make South Carolina the 38th state to leaglize MMA.
