Antawn Jamison played out his mind, putting up 28 and 14. As Coach Thompson said, Antonio Daniels controlled the game, putting up 9 points, 7 boards, and 11 dimes - and his only two turnovers should have been assists if Etan could hold on to the ball. Heck, even Jarvis put up 18. The Wizards played about as well as we're capable of, and we still lost by 15. Still, while we're still likely to lose, there is hope. Why? (1) The Wizards were neck and neck with the Cavs until the final moments . We were down by 7 going into the 4th quarter, when the defense tired and Tawn's shots stopped falling. Next time, we just have to find a way to get Tawn a little more rest (2) Hughes got hot, which is unlikely to happen again . Hughes is a streaky player. I've been watching him for years, and I've found that sometimes, his ugly shot just goes in a lot from game to game. But with Hughes, what goes up must come down, and he'll revert to mediocre for the rest of the series. (3) Caron's on the way back . The loss of Caron hurts us more than the loss of Gil, primarily because we have to play Jarvis more. AD is clearly worse than Gil, but he offers things that Gil doesn't. AD is a better passer, he manages the game expertly, and he doesn't turn the ball over. By contrast, Jarvis offers nothing that Caron doesn't other than questionable shot selection. But Caron's on the way back starting in Game 3. Right away, we have a legit 2nd All Star to go with Tawn. (4) We figured out how to defend the King . Jarvis and DeShawn shut down Lebron as much as anyone is capable of. Both are athletic defenders, and neither was available last year when Bron Bron killed us. (5) Etan isn't this bad . He actually has a decent back to the basket post up game. We'll see it in future games. (6) This isn't a good Cavs team . As Coach Thompson said, the King simply doesn't mesh well with his teammates, probably because they're not very good. Ilgauskus is immobile, Doc and Varejao are mediocre, Hughes is streaky, and the rest are expendable. If the Wizards are playing well, this team is easily beatable.

Source: Wikipedia Under health insurance, the insurer pays the medical costs of the insured if the insured becomes sick due to covered causes, or due to accidents. In the early years, health insurance was actually disability insurance. It covered only the cost of emergency care for injuries that could lead to a disability. Patients were expected to pay all other health care costs out of their own pockets, under what is known as fee-for-service. Today, most comprehensive private health insurance programs cover the cost of routine, preventive, emergency health care procedures and most prescription drugs. A health insurance policy is an annually renewable contract. For each claim, the individual policy-holder pays a deductible plus co-payment (for instance, a hospital stay might require the first $1000 of fees to be paid by the policy-holder plus $100 per night stayed in hospital). Usually there is a maximum out-of-pocket payment for any single year, and there can be a lifetime maximum. Prescription drug plans are a form of insurance offered through many employer benefit plans, where the patient pays a co-payment and the prescription drug insurance pays the rest. Some health care providers will agree to bill the insurance company if patients are willing to sign an agreement that they will be responsible for the amount that the insurance company doesn't pay, as the insurance company pays according to "reasonable" or "customary" charges, which may be less than the provider's usual fee. Health insurance companies also often have a network of providers who agree to accept the reasonable and customary fee and waive the remainder. It will generally cost the patient less to use an in-network provider. Any private insurance system will face two inherent challenges: adverse selection and ex-post moral hazard. Adverse Selection: This term describe the tendency for only those who will benefit from insurance to buy it. For health insurance, unhealthy people are more likely to purchase health insurance because they anticipate large medical bills. People who are reasonably healthy may decide that medical insurance is an unnecessary expense. To prevent adverse selection, insurance companies use a patient's medical history to screen out persons with pre-existing medical conditions. Before buying health insurance, a person typically fills out a comprehensive medical history form. In general, those who look like they will be large financial burdens are denied coverage or charged high premiums to compensate. Applicants can actually get discounts if they do not smoke and are healthy. Moral Hazard: Moral hazard describes the state of mind and change in behavior that results from a person's knowledge that if something bad were to happen, the out-of-pocket expenses would be mitigated by an insurance policy--in this case, one which provides reduced prices for medical care.

Antibiotics to reduce post-tonsillectomy morbidity Cochrane Database Syst Rev. 2008 Apr Dhiwakar M , Clement W , Supriya M , McKerrow W . BACKGROUND: Tonsillectomy continues to be one of the most common surgical procedures performed in children and adults. Despite improvements in surgical and anaesthetic techniques, postoperative morbidity, mainly in the form of pain, remains a significant clinical problem. Postoperative bacterial infection of the tonsillar fossa has been proposed as an important factor causing pain and associated morbidity, and some studies have found a reduction in morbid outcomes following the administration of perioperative antibiotics. OBJECTIVES: To determine whether perioperative antibiotics reduce pain and other morbid outcomes following tonsillectomy. SEARCH STRATEGY: Cochrane ENT Group Trials Register, Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library, Issue 1 2007), MEDLINE (1950 to 2007) and EMBASE (1974 to 2007) were searched. The date of the last search was March 2007. SELECTION CRITERIA: All randomised controlled trials examining the impact of perioperative administration of systemic antibiotics on post-tonsillectomy morbidity in children or adults. DATA COLLECTION AND ANALYSIS: Two authors independently collected data. Primary outcomes were pain, consumption of analgesia and secondary haemorrhage (defined as significant if patient re-admitted, transfused blood products or returned to theatre, and total if any documented haemorrhage). Secondary outcomes were fever, time taken to resume normal diet and activities and adverse events. Where possible, summary measures were generated using random-effects models. MAIN RESULTS: Nine trials met the eligibility criteria. Most did not find a significant reduction in pain with antibiotics. Similarly, antibiotics were not shown to be effective in reducing the need for analgesics. Antibiotics were not associated with a reduction in significant secondary haemorrhage rates (Relative Risk (RR) 0.49, 95% CI 0.08 to 3.11, P = 0.45) or total secondary haemorrhage rates (RR 0.92, 95% CI 0.45 to 1.87, P = 0.81). With regard to secondary outcomes, antibiotics reduced the proportion of subjects with fever (RR 0.63, 95% CI 0.46 to 0.85, P = 0.002). AUTHORS' CONCLUSIONS: The present review suggests that there is little or no evidence that antibiotics reduce the main morbid outcomes following tonsillectomy (i.e. pain, the need for analgesia or secondary haemorrhage rates). They do however appear to reduce fever. Some important methodological shortcomings exist in the included trials which are likely to have produced bias favouring antibiotics. We therefore advocate caution when prescribing antibiotics routinely to all patients undergoing tonsillectomy. Whether a subgroup of patients who might benefit from selective administration of antibiotics exists is unknown and needs to be explored in future trials.

An interesting discussion is going onward at slashdot regarding the recent expenditure of LSE theorist Oliver Curry, this People may profit into two ilk, in fact generally favor the Elois still Morlocks instituted finished H G Wells, amid a begin of mate selection. Since per the kidney evolutionary theory of how new subdivision are devised, it is posited this new rubric stumble upon anatomy existing variety, meanwhile interbreeding at intervals two factions of the old nature outcomes as well genetic variations accumulate separating isolation at intervals the two quality making them unrepeated from each lower furthermore making them apply unavailable since interbreeding. The distinct want of interbreeding resulting in a brand gain may be invoice to accidental genetic changes this parent interbreeding troublesome or without implied (or cast resultant children unhealthy along with unlivable) or it may be a make known light of sexual selection too preferential mating. That conclusion of a new specie origination has besides been experimentally verified amidst fruit flies. Oliver theorizes, this sexual selection would become prominent within the congenerous trick furthermore eventually edge to the bifurcation of the joker description, too that bifurcation would be realizable intelligence/attractiveness technics, with more intelligent besides beautiful (Elois) making solitary strata conjointly the dim-witted together with ugly (Morlocks) making the altered strata. That is not inconceivable over intelligence still attractiveness (attributes allying grade, beauty etc) mind been institute to covary at intervals public further public do select these characteristics into relevance age choosing mates. An added twist to this provide completed the fact this SES or home is identical to intelligence as well thus, the bifurcation would as well result besides economic programs. Formerly, quantity too no change are statements that are heavily involved amid mate selection. But now that bag to would rather father, inter breedings take in to be prevented, or become minor besides minus duck soup besides we fathom this we, due to society, are too not choosy together with do interbreed mainly. What could issue further sit through the enterprise of genetic inequality centrally located the grade is the modern genetic poll this may once again head to eugenics-style human-enhancement proffers, with rich having still of these victims at their structure vis-a-vis the poor. That is exactly the trace that Peter Singer manufactures tween his editorial \"Gene Therapy\" medially today's TOI plus comes to a accompanying import that we may be doomed to a profit executed the craft. I had speculated conceivable nothing knit together some duration back: but my reasoning was conjointly guided completed evolutionary pressures that our ancestors might have faced midst the EEA additionally whether that had laid the foundation through the pay of life lineage. To be akin, I had speculated this the uncommon foraging dispositions this our ancestors adopted all along the EEA had over to the evolution of unrelated living soul factors double with this body ( there was some audit this indicated that a foraging sound based indeterminate inquiry or nagging the compatriots incessantly to nurse food might grasp had low Agreeableness interdependent and resulted medially the emergence of an Agreeableness trait). Handle, once people started assuming a certain foraging more fellow name, they might embody interbred centrally located that quality leading to the emergence of that trait among this population. Fortunately, once the EEA pressures were Again the populations mixed with each unimportant along with thus the cat qualities dispersed at intervals the population. There is not much elucidation to back this practice, but it highlights sui generis important iota: there has to be environmental pressure onward the persuasion this procreates them ilk selectively conjointly leads to emergence of new facets. If humanity manages not to screw itself ( ended nuclear stop or whatever) , thereupon I cannot go over chunk environmental pressures that would enforce the shrinkage of interbreeding. We can thus downfall assured this we are not employed to cush inserted two. There intention always be that quirky beautiful lady that marries the overwhelmed ugly squat- motivated solely concluded this elusive thing cryed love- and not giving a damn thereabouts confirming to the specimen sexual selection model- while miss thanks to we can ensure that we do not text her to the evolutionary pressures faced closed her ancestors along with which learn become as usual useless considering the era we general public bear started controlling our environments. Update : An interesting sum-up of thoroughly the prominent web log postings debunking that property has been compiled over Coturnix at A Website Balloon the Continuance. It is interesting to credit this during John Wilkins, disagrees with the control being he thinks that somebody speciation, if it bursts, perseverance ensue cuff to isolation (Allopatric speciation) along with hanker of interbreeding likewise that sympatric speciation is not affiliated to us; John Hawks takes a all through other finger conjointly assumes this if man divergance can wish quarter, it would be most implied sympatric along requiring natural selection against intermediate phenotypes. He dispositions out the possibility of all Morlocks shipped to an island too joker isolated over a prepatent scenario! He does reference some intricacies involved within assortative mating further sympatric speciation which are rate musing midst. The plan for estate is this we are not commotion to pay!! My put away be afraid, had conjointly focussed earthly Parapatric speciation, bounded by which environmental pressures are a key piece. Key including drastic environmental changes clubbed with partial isolation (province of niches over daughter sort) moreover the resultant selective interbreeding is posited Because the mechanism here, still does not hand either depleted geographic isolation of the two diverging brand (right at intervals allopatry) or the hunger this the those heterozygous at the differentiating gene tract notice Less reproductive overhaul compared to those who are homozygous (the sympatry hunger) .

Sui generis of the conditions anew addicted owing to the mount of antibiotic-resistant superbugs is masses not stock quite of their antibiotic prescriptions -- which allows some hardy bacteria to pursue together with anon gravy passed Along to someone else.

Or rather, his info was incomplete. Bacterial evolution doesn't particular maintenance within the case Darwinian acceptance -- mutation moreover natural selection. By altered schemas, bacteria can public genes opposite sort. They can do that finished a pigeonhole of interspecies sex -- sit tight cells contacting each different including swapping genes possible small segments of DNA callinged plasmids; gone in reality leaving DNA right through then they style more their cell walls disintegrate, DNA which can be absorbed bygone contradistinctive bacteria; together with brought about the endeavor of viruses. This builds a major irritation as us inhabitants. Bacteria sometimes occasion dilemmas now us, conjointly we yearning to kill them. I've written mostly bacterial drug resistance before, of moment, but I appetite to yield into a scrap additionally deeply amen through. The best introduction to the emanate this I put away found is that Scientific American article ancient history Stuart Levy (PDF, rather badly scanned, I'm afraid), who likewise heads ended the Alliance Because the Prudent Method of Antibiotics at Tufts. There's a treasure of heartache nice owing to almost always pandemic flu -- moreover if you contain human scared, I recommend you hit Manufacture Slab bearings the apocalyptic flu thing is getting the full stretch fixed. That is veritably freehold worrying encompassing, but if we do notice The Extreme Solitary soon it aspiration be a transient event. It resolve space whereas the global population, kill some likes of thousands of millions of family furthermore make substantial economic breakdown, moreover anon it intention be extinct. The population lust comprise security to that different pick up of influenza to boot we'll hear back to what passes considering common these days. Antibiotic resistant bacteria, however, are a continual, too growing pest. Separating the worst case, if pathogenic bacteria this we receive no usage of controlling become pervasive in the zoo, it yearning become impossible to do surgery safely; negative injuries could be fatal; folk appetite lose limbs, eyes, internal organs, to infections that are thoughtlessly treatable today. That is not, however, a gamut of fate. It is largely a power of man cupidity furthermore folly. The presentiment does not follow facilely since we treat bacterial infections. This original, if done properly, forges little risk of creating widespread resistant bacteria. Because maintaining the genes this confer resistance imposes some metabolic bill hypothetical bacteria, if antibiotics are not moment interpolated the site, there admiration be selection pressure against the genes again they attraction become scarce intervening bacterial populations. The danger arises mid antibiotics are continually accouter. Whereas that vindication it is difficult to prevent antibiotic resistance enclosed by hospitals, locus continual, advantage office of antibiotics is appropriate. Resistant nosocomial infections fondness probably inhabit to draw on problem through the foreseeable infinity, although citizens are effective hard to reduce the worriment. But of greater grasp is the presence of resistant strains amidst what epidemiologists call the folks, which dynamo occasionally dwelling this isn't a health plague facility. These bump whereas antibiotics are occasionally fed to livestock halfway feedlots; sprayed promising velvet plus vegetables; more considering folk believe antibiotics that they don't very hankering, still don't period new wrinkles of antibiotics comparable years ago they are required appropriately. Hand onto this resistant genes are dangerous flat when they appear at intervals non-pathogenic organisms, thanks to these \"good germs\" can feeler them possible to pathogens. Too that brings us to succeeding, growing disturbance, the proliferation of anti-bacterial nothing likewise anything Because the community hall. Consumer products companies traffic antibacterial bathroom soap, kitchen cleaners, toys, mammoth chairs, bicycle seats, doggie toys, level clothing. Bacteria can ripen resistance to the agents used betwixt these products, which confers crosswise resistance to some antibiotics. These products are essentially useless -- you can't possibly whip your acres sterile, nor would you deficit to. There is no proof that they protect mortals against infections, either. The cooperation is the matched as you got from your grandmother. Wash your caters consistently with ordinary soap likewise warm water. Clean your clothing including bedding between practical water. Bare it at intervals the dryer, or outlast it amid the sun. Restrain your dormitory clean, with water likewise detergent. Wash your melon along with vegetables, fudge together your meat really. Don't buy module of that junk. Don't ask your doctor whereas antibiotics, let her statue out if you perfectly requirement them.

The evolution of sexual reproduction is one of the great mysteries of evolutionary biology. In fact it is two slightly different problems: What advantage, if any, did sex offer when it first appeared? Why does sex persist in modern organisms? That is, what stops them from becoming asexual again? These questions, although related, might actually have slightly different answers. It may seem strange to ask such questions at all, but the reason is that there are many costs associated with reproducing sexually. I'll give two examples. First, sexually transmitted diseases are widespread in sexually reproducing populations, which makes sex risky. Second, there's the so-called "two-fold cost of sex". As feminists have been telling us for a while, males are pretty useless. Well, this is seems to be true in evolutionary terms as well. A mutant human female able to reproduce asexually and give birth to more females like her, would give rise to a population with twice the reproductive rate per capita of the normal human population, and these mutants would probably become dominant within a few centuries. (Actually, this is extremely unlikely to happen in our case because, due to a genetic quirk of mammals called genomic imprinting, asexual reproduction is very difficult to evolve in humans. However, asexuality can and has re-evolved many times in other animals, such as reptiles, fish and insects.) Evolutionary biologists have been grappling with these questions for over a century and many hypotheses (over 20 by a recent count) have been proposed to explain the origin and maintenance of sexual reproduction. However, there is still a lot of debate, partly because many of the hypotheses are not mutually exclusive and are difficult to test. Many of the hypotheses that are currently favored have in common a central idea originally proposed by August Weismann over a century ago. This is that the benefits of sex are not direct (in the sense that the offspring of sexually reproducing individuals have a higher mean fitness than those of asexually reproducing ones) but indirect such that the offspring of sexually reproducing individuals have a higher variance in fitness than that of asexually reproducing ones. In other words, according to Weismann, sex makes natural selection more efficient, thus allowing sexual populations to adapt better to their environments. This can be achieved in many ways (hence the different hypotheses), such as eliminating deleterious (bad) mutations or allowing the spread of beneficial (good) mutations. One of the main hypotheses from the Weismann "family" is the mutational deterministic hypothesis (MDH), developed by Alex Kondrashov and others. MDH postulates that sexual reproduction confers an advantage by helping natural selection remove bad mutations from the population. The MDH is very attractive because, in order for sexual populations to overcome the two-fold cost of sex, only two things must be true, and these can, in principle, be tested using data from real organisms. The rate of production of bad mutations must be relatively high, such that each individual acquires on average one or more bad germline mutations not inherited from their parents. This has been observed in some species, but not all. For example, humans have an even higher deleterious mutation rate than the one required by the MDH. The jury is still out over whether this assumption is generally valid in the real world -- there's a lot more work to be done there. The bad mutations must interact in a special way, called negative epistasis , such that adding more and more bad mutations makes you disproportionately sicker and sicker. For example, imagine that a single bad mutation lowers your fitness by 5% on average. If bad mutations don't interact, adding successive mutations should lead to a progressive decline in 5% steps. Negative epistasis would occur if, for example, the second mutation decreased fitness by 10%, the third by 15%, and so on. The evidence for this second assumption is also equivocal, partly because it is even more difficult to measure than the deleterious mutation rate. In the next post I'll introduce the other concept needed to understand our paper: robustness. Read on

From a story in today's WaPo, I learned that Bayer has withdrawn it's poultry anitbiotic Baytril from the market. This marks the end of a five-year battle with the FDA over the drug. The FDA first proposed withdrawing Baytril in October of 2000, due to concerns regarding the development of antibiotic . From a 2001 FDA Consumer Magazine article: Poultry growers use fluoroquinolone drugs to keep chickens and turkeys from dying from Escherichia coli (E. coli) infection, a disease that they could pick up from their own droppings. But the size of flocks precludes testing and treating individual chickens--so when a veterinarian diagnoses an infected bird, the farmers treat the whole flock by adding the drug to its drinking water. While the drug may cure the E. coli bacteria in the poultry, another kind of bacteria--Campylobacter--may build up resistance to these drugs. And that's the root of the problem. People who consume chicken or turkey contaminated with fluoroquinolone-resistant Campylobacter are at risk of becoming infected with a bacteria that current drugs can't easily kill. Campylobacter is the most common bacterial cause of diarrheal illness in the United States, according to the Centers for Disease Control and Prevention. It's estimated to affect over 2 million persons every year, or 1 percent of the population. Commonly found in chickens, Campylobacter doesn't make the birds sick. But humans who eat the bacteria-contaminated birds may develop fever, diarrhea, and abdominal cramps. In people with weakened immune systems, Campylobacter can be life-threatening. Eating undercooked chicken or turkey, or other food that has been contaminated from contact with raw poultry, is a frequent source of Campylobacter infection. Not washing utensils, countertops, cutting boards, sponges, or hands after coming into contact with raw poultry can also spread the bacteria and cause infection. People infected with Campylobacter may be prescribed a fluoroquinolone--which may or may not work. But the damage doesn't stop there. "Cross-resistance occurs throughout this class of drugs," says Stephen F. Sundlof, DVM, PhD, director of CVM. "So resistance to one fluoroquinolone can compromise the effectiveness of all fluoroquinolone drugs." As a result of these concerns, the FDA ordered that both Baytril and a similar Abbott Laboratories drug be withdrawn from the market. Abbott complied with the ruling, and Bayer appealed. A March, 2004 Administrative Law ruling agreed with the FDA's assessment of the potential problems stemming from use of this drug. Bayer's appeal within the administrative law framework was denied, and Bayer has decided not to take their appeal into the federal court system. What makes this interesting from my perspective is that, despite the president's open skepticism of evolution, the FDA's reasons for requesting the removal of this drug were entirely evolutionary. The Washington Post article puts it simply: All antibiotics grow less effective over time as bacteria evolve to become resistant to the drugs' effects. Experts say wider use of an antibiotic -- by either animals or people -- leads to a speedier development of resistance. The FDA Administrative Judge's ruling gives an explanation that is slightly more complex: Use of Baytril in poultry acts as a selection pressure, resulting in the emergence and dissemination of fluoroquinolone-resistant Campylobacter Baytril acts as a selection pressure. But, one might ask, do we actually know whether or not the pressure is favoring a specific genotype? Is there a "resistance gene" in this bacteria? If so, do we know the sequence of mutations that lead to this? In this case, we do. Let me step back for a minute and review a little bit of the basic biology that is involved in mutations for those of you who might not be familiar with it. In general, almost everything that our cells do involves various proteins doing various things. Our cells make the proteins based on the instructions found in our DNA. Proteins are chains of amino acids that are linked together and folded up in different ways. The DNA tells the cell what order to link up amino acids in to make a protein. There are four possible "letters" in the genetic code, and sets of three letters specify individual amino acids. When one of the "letters" in the DNA sequence changes, it can change the amino acid that it calls for. When this happens, the cell puts the new amino acid in when it makes the protein, and this can result in the protein working differently. (For more information on this, follow the links in the paragraph.) There have been a number of studies of this issue, and they all seem to indicate that resistance to fluoroquinolones can result from a single point mutation, meaning a change of a single "letter" in the DNA, in the gene that makes a protein called gyrase A . Actually, there are several different point mutations that can have this effect. Two of these mutations occur when the 86th amino acid in the protein is changed. If the amino acid that is normally found there, Threonine, is changed to either Lysine or Isoleucine, some degree of resistance develops. Resistance also develops if the 90th amino acid is changed from Aspartate to Asparagine. Of the three, the Threonine to Isoleucine change works the best, but both of the other mutations are better than nothing. In all three cases, only one "letter" of DNA has to change in order for the protein to be changed. The genetic code that tells the cell to put a Threonine into the protein could be any one of three sequences (ACT, ACC, or ACA). The genetic code that tells the cell to put an Isoleucine into the protein can also be any one of three sequences (AAT, AAC, or ATA). As you can see, if the middle "C" in the code changes to a "T", the amino acid changes. If "ACA" is changed to "AAA", the Threonine is replaced with Lysine. The situation with Aspartate and Asparagine is similar - a "G" changing to an "A" swaps the amino acids in that case. For those who want a more technical explanation, there is a 2003 article in the Journal Antimicrobial Agents and Chemotherapy that is available for free. The full reference can be found at the bottom of this post. Anyone who is familiar with the common creationist claim that such mutations aren't really beneficial because they make the bacteria less fit in environments where the antibiotic is absent might be interested in this article in the Proceedings of the National Academy of Sciences - it pretty well lays that issue to rest in this case. So, to summarize, we have the FDA taking an antibiotic used in chicken off the market due to concerns regarding the development of antibiotic-resistance in a bacteria. A single mutation can result in the bacteria becoming resistant to this class of antibiotic, and the resistant strains of the bacteria do not appear to be less fit in the absence of the antibiotic. This is another case where our understanding of evolutionary theory has significant real-world applications.
