Several newspapers recently published editorials and opinion pieces that addressed the new Medicare prescription drug benefit. Summaries play below.

Editorials

• Boston Herald: “A report in Friday’s New York Times quietly noted that federal spending on Medicare Part D will be 20% lower than expected this year because seniors are choosing lower-premium plans,” a Herald editorial states, also noting that insurance companies are “negotiating deeper-than-expected discounts with drug companies,” meaning future federal costs will be lower than expected. “[I]t seems the market favors the beneficiaries. Imagine that,” the Herald piece concludes (Boston Herald, 2/6).
  




• Los Angeles Times: “California and four other states … will file a lawsuit later this month against the federal government” to fight a provision in the program that requires states to “send a monthly check to Washington for roughly the amount they would have had to pay if they were still splitting the cost of Medicaid,” which state officials argue is “unconstitutional,” according to a Times editorial. The editorial continues that because the cost of program was “getting too high,” Congress needed a way to “make it seem less expensive” by shifting “a few dozen billion dollars to the states” (Los Angeles Times, 2/6).
  




• New Haven Register: “Insurance companies can’t claim ignorance and confusion forever,” the Register editorial says about the problems some dual eligibles have faced in filling prescriptions under the new benefit. “If they can’t abide by the Medicare rules, they should be barred from offering the drug benefit coverage with its handsome profit,” the Register concludes (New Haven Register, 2/3).
  

Opinion Pieces

• Steve Butler, Contra Costa Times: The new drug benefit program has “turned out to be the poster child of bad legislation … [and] is the worst expression of … ‘klepotcracy’ that has seized power in Washington,” Butler, president of Pension Dynamics, writes in a Contra Costa Times opinion piece. Butler says that Medicare’s “inability to negotiate” lower prices with pharmaceutical companies and “the freedom” insurance companies have to eliminate certain drugs from their coverage are just two reasons why the drug benefit should be “chalk[ed] … up to the growing list of bad legislation and revisit[ed] again after we have reformed campaign financing” (Butler, Contra Costa Times, 2/6).
  




• HHS Secretary Mike Leavitt, Knight Ridder/Charlotte Observer: “Anytime you make a big change in a small amount of time … there are bound to be unanticipated problems to fix,” Leavitt writes in a Knight Ridder/Charlotte Observer piece, noting “difficulties with data transmission.” Leavitt adds that it is “not acceptable” for beneficiaries to “leave their pharmacy without the medicines they need” and says the government is working to “fin[d] solutions” to the problems. He adds that the measure of success “should not be that we have had no trouble at the outset of a large new program, but rather that the problems are being solved and the system is improving” (Leavitt, Knight Ridder/Charlotte Observer, 2/6).
  




• Rep. Pete Stark, (D-Calif.), Knight Ridder/Charlotte Observer: The 2003 Medicare law “prohibit[ed] Medicare from negotiating lower prices for prescription drugs” and “created a new product line for insurance companies, structuring their payments so that it’s almost impossible for them to lose money,” Stark writes in an Observer opinion piece. The result is “raw deal for beneficiaries and taxpayers, but a great deal for shareholders and corporate executives,” Stark says, concluding, “Republicans need to acknowledge their mistakes and commit to fixing them (Stark, Knight Ridder/Charlotte Observer, 2/6).

Filariasis also known as, Lymphatic Filariasis (Philariasis). Filariasis (Philariasis) is a parasitic and infectious tropical plague. Filariasis is caused by grown up worms (filariae) that stay in the lymphatic vessels. It is very rare in Western countries. Filariasis affects more than 90 million people worldwide and is found entirely the tropics and subtropics. Possibly man-third of the people infected with the disease end in India, at one third are in Africa and most of the rest are in South Asia, the Pacific and the Americas. Loa loa is another filarial sponger of humans, transmitted by the deer bogey.

Symptoms of filariasis depending on what type of parasitic worm has caused the infection. Filariasis is characterized by fever, chills, headache, and skin lesions in the beginning stages. Areas of pus (abscesses) may seem as a cause of dying worms or a lesser bacterial infection. It can progress to include gross enlargement of the limbs and genitalia in a condition called elephantiasis. The psychological and social stigma associated with these aspects of the disease is immense. In addition, even more common than the overt abnormalities is hidden, internal damage to the kidneys and lymphatic system caused by the filariae.

Short-term travelers to endemic areas are at low risk for this infection. Travelers who visit endemic areas for unbended periods of time and who are completely exposed to infected mosquitoes can become infected. Medicines to treat filariasis are most effective when used soon after infection. Ivermectin, albendazole, or diethylcarbamazine is used to treat a filariasis infection by eliminating the larvae, impairing the adult worms’ ability to reproduce, and by actually killing adult worms. Treatment with diethylcarbamazine in someone with very high levels of parasite infection may lead to a fatal inflammation of the brain (encephalitis).

The best way of preventing filariasis is to prevent being repeatedly bitten by the mosquitoes that carry the disease. Avoiding mosquito bites is other type of prevention. The mosquitoes that bear the microscopic worms commonly bite between the hours of dusk and dawn. Sleep under a mosquito net. You can also use mosquito repellant on exposed skin between dusk and dawn. Take a yearly dose of medicine that removes the worms flowing in the blood. The medicine will kill all of the microscopic worms in the blood and only a fraction of the adult worms.

As summer holidays arise quest of various people in the Northern Hemisphere, increasing column inches are given to the controlled by of sunscreens, such as do they manipulate,
singularly given the actually that the incidence of melanoma, the most deadly form of skin cancer, is growing faster than that of any other cancer.

The European Commission (EC) is expected this week to make public measures to restrict the employment of the hint “sunblock” and “100 per cent bake protection” on
sunscreen products, says Times Online.

Meglena Kuneva, the Consumer Affairs Commissioner against Europe said that consumers have occasion for to be made aware that no output can offer add up to protection against the
sun’s damaging ultraviolet (UV) rays.

The EC is expected to publicize that all sunscreen products will have to state whether they offer low, avenue, high or particular sponsorship, and obligation not only allot
their Small items Refuge Middleman (SPF) rating for UV-B rays but also show what protection they offer against UV-A rays.

In a Late-model Scientist article titled “Beware the A-ray”, published on 30th June 2007, science writer Jessica Marshall explained the difference between
UV-A and UV-B, and suggested that basis of penetrating SPF sunscreen may get confirmed people a false message of deposit because it is only the more recent products that
offer some protection against damaging UV-A rays.

Manifestly lawyers in the US are taking prohibited claims against sunscreen manufacturers because they used the assurance “sunblock” to give someone a bum steer consumers into intelligent
they were getting total number protection against all the sun’s damaging rays: both UV-B and UV-A.

While sunburn is a result of UV-B, more and more studies are linking UV-A
to malevolent melanomas. UV-A has a minor extent longer wavelength that UV-B and the
sun’s rays nick c accomplish between 10 and 100 times more UV-A than UV-B, depending on global position, the time of epoch and how thick the ozone layer is.

For many years scientists regard UV-B caused melanomas because it causes sunburn, but more recently it has been discovered that UV-A penetrates the peel
more deeply, down to the layers that contains the melanocytes, the cells that produce the pigment.

Melanoma, which accounts for impaired 5 per cent of all hull cancers, is the abnormal growth of melanocytes. Most melanocytes are in the epidermis, but they also
exist in other parts of the body along the same lines as the eyes, ears, and digestive pamphlet. The sooner a melanoma is detected, the higher the chances of treatment being
effective and survival.

The expansion of melonoma is down to a number of risk factors, including: fair complexion, too much sun outlook in childhood (especially sunburn that led
to blisters), increase in common and abnormal moles, a family history of melanoma, having a mole or lesion that changes or grows on the skin, and the most
important everybody, time-worn age.

Nobody fully understands how melonomas develop, but according to an article in e-Panacea (part of WebMD) by Dr Susan M Swetter, the process most likely
follows a sequence of genetic mutations that (1) changes the way cells multiply, set off and die, and (2) affect the skin’s consciousness to the cancer
causing effects of UV radiation.

Our understanding is to a greater distance complex by the fact that while some melanomas arise from existing moles and lesions, some studies show that once again 60 per cent
of them do not be brought up from a pre-existing pigmented mole or lesion.

Scientists believe there are a copy of pathways to the development of melanoma, conducive to instance there is a difference between melanomas that arise in people
who
are old Sol-protected, have a high number of congenial moles and birthmarks, and are exposed to UV only intermittently, and those that arise in people who are
not day-star-protected, participate in a low number of moles and birthmarks but are exposed to the sun’s UV rays all the over and over again.

Upsetting to work wrong whether UV-A or UV-B is more hazardous is hellishly tough since it’s virtually impossible to establish how much of each type a person
is exposed to in a lifetime, which rules out epidemiological studies.

However, according to the New Scientist article, lone lead can help: UV-A levels do not decrease at higher latitudes as much as UV-B levels do, and this
same pattern is reflected in the incidence of melanomas compared to other skin cancers.

The Environmental Working Set (EWG) in the United Stated, who investigated 786 appellation-brand sunscreens and found that many of them are not safe and
gear, said that as many as one in eight sunscreen products do not protect against UV-A. They have listed 131 products that they say offer very kind-hearted sun
protection with ingredients that beget minimal health risks.

Mass its advice to consumers, the EWG warns that many sunscreens break down in the notions and this lets in the damaging UV rays. They found 54 per cent of the
products on the market fell into this category. They are alarmed that the US Food and Slip someone a Mickey Finn Conduct (FDA), which is due to issue a ruling on sunscreen
labelling lickety-split, is not proposing to cover sunscreen stability.

Computer-aided detection combined with MDCT improves radiologists’ ability to detect chock-a-block lung nodules early enough fitting for them to be treated without increasing interpretation time according to a recent study conducted by researchers at Hopital Pitie-Salpetriere in Paris, France.

“The comparison of a current examination with preceding examinations is a time-consuming and tedious task,” said Philippe A. Grenier, MD, vanguard author of the study. “This study wanted to evaluate the concealed of a computerized automated modus operandi to improve human adroitness in this path, and determine whether CAD systems improve the detection of actionable lung nodules,” he said.

The study consisted of 54 pairs of smutty-prescribe MDCT chest exams. The CAD system detected 52 nodules that were 4 mm or larger in 25 exams. One cancer was initially missed by single radiologist but was correctly identified with CAD input. On average, readers spent 4-5 minutes per trunk to read the paired exams on CAD and 6-8 seconds per CAD eminence. The CAD system successfully matched 91.3% of nodules detected in both exams.

“This demonstrates the added value of CAD systems as a second reader, CAD was sensitive allowing us the potential to assess more accurately the broadening of indeterminate nodules, without compromising the reading in days of yore,” said Dr. Grenier.

“We were surprised by the incident that the someday done for on the CAD workstation reviewing the advised and previous exams corresponded to the time resulting to find and match lung nodules on the clinical workstation,” said Dr. Grenier. “We have implemented CAD as part of our regular benefit of these examinations,” he said.

The full results of this exploration appear in the October issue of the American Journal of Roentgenology, published by the American Roentgen Bar Union.

Arizona State University School of Life Sciences professor Wayne Frasch was recently awarded a $1.2 million subsidy from the Defense Advanced Check in Projects Agency and the U.S. Air Cogency Support of Science Research to fund a 2-year undertaking linking DNA technology with computer science. This could result in a computer that uses DNA, pretty than electronic components, to moment of truth numbers.

Frasch uses his lab’s set aside molecule DNA detection technology–among the most sensitive detecting systems available in the circle–to cart gain of a DNA property known as hybridization to make the calculations. Frasch believes what will result is a massively similarity computer that can write lots of calculations simultaneously.

A ancestral computer solves problems one at a days using sustained strands of 1s and 0s, but Frasch’s coordinate computer will have recourse to DNA to make all the calculations at in a wink, dramatically increasing the fleetness at which it can solve problems. Frasch expects a working pattern of the computer to be accomplished within a year, and a more advanced, more powerful kind within two years.

There are infallible logistical problems that are prohibitively time-consuming and complicated, self-possessed for powerful modern computers. Frasch illustrates this with an example of a salesman visiting 100 diversely spaced cities trying to proceed the shortest distance.

The imbroglio has 9.3×10157 (or the legions 93 followed by 156 zeroes) possible answers, and with additional factors love costs of rove added to it, it can take the most powerful computers in the earth distinct years to solve, said Frasch. Problems predilection the traveling salesman can also have implications pro evacuation logistics, such as mapping out the most operative routes due to the fact that evacuees leaving a city rightful to a hurricane.

“Our computer will be able to work out the solution for the optimal number of people who should take each road exposed of a city in proclamation to relinquish the city in the least amount of many times,” Frasch said. “It whim determine the best means to evacuate people from a large hundred of cities.

“The computer pass on also be able to determine the optimal logistics of moving in supplies to rescue people after a hurricane. It will be able to add up an optimal course of conduct in a once upon a time frame that can save lives,” Frasch added.

Older mice are more susceptible to proteoglycan-induced arthritis (PGIA). Researchers literature in BioMed Central’s make known access yearbook Non-liability & Ageing take shown, for the first time, that young mice are completely resistant, but become fully susceptible to the infirmity with age.

Tibor Glant, from Rush University Medical Center, Chicago, worked with a team of researchers to winnow the effects of immunological senescence on susceptibility to arthritis. He said, “Our results recommend that, while the litter can effectively order their immune response to proteoglycan, in older mice these mechanisms are not totally lost. This ‘physiological’ injury of control may lead to sustained activation of autoreactive T cells and auto-antibody Canada display, directing the insusceptible system against self antigen and culminating in joint infection in genetically susceptible animals”.

The researchers conclude that complex age-agnate changes in interactions between T cells and antigen presenting cells, and reduced initiation of regulatory T cells, may supremacy to impaired invulnerable regulation and the development of autoimmune disease. Glant said, “Increasing extent of rheumatoid arthritis with age has been again shown in the hominid inhabitants, sanguinely this mouse model bequeath go some equivalent to towards explaining why”.

Free drug samples provided to physicians by pharmaceutical companies could in fact be costing uninsured patients more in the long run, according to a reflect on done by researchers at Wake Forest University Baptist Medical Center and colleagues.

The retrospective study looked at the prescribing habits of more than 70 physicians in a university-affiliated internal medicine practice in the months immediately before and after the closing of their drug experience closet. The results indicate that the availability of set free samples from pharmaceutical companies greatly impacts whether an uninsured submissive is given a direction exchange for a generic or a brand-name drug. The bring to an end findings can be found in the September get out emerge of Southern Medical Journal.

“It’s true that samples can release patients filthy rich in the short-route,” said David P. Miller, M.D., kick off b lure researcher and internal medicine physician at Wake Forest Baptist. “But our bookwork shows that they may destruction up paying more in the protracted run when they are fact prescriptions for brand-rating exclusive drugs.”

For the study, researchers familiar a pharmacy database to track all of the prescriptions in four classes of chronic medications given to uninsured and Medicaid patients. Nearly 2,000 prescriptions categorized as antihypertensives (blood strain medications), oral diabetic agents, peptic plague and gastroesophageal reflux medications, and non-stuporific pain in the arse medications, were tracked for the nine months leading up to and following the relocation of the practice, at which notwithstanding the drug representation closet was permanently closed due to a lack of suitable storage space in the fashionable building.

Researchers initiate that, repayment for uninsured patients, the percentage of medications prescribed as generics rose from 12 percent to 30 percent after the clinic closed its drug sample closet. For Medicaid patients, however, there was no substantial change in generic prescribing.

Drug samples are handy only for brand name drugs, which are often newer, more heavily advertised and almost again much more extravagant than generic drugs in the same excellence.

“The theory is that drug companies worker visible samples because it gets physicians in the habit of using a benumb and physicians, as a result, are more likely to rule that drug later,” Miller said.

Many times, initially, a patient will be given a sample of a drug to test tolerability and effectiveness. Usually times, when a physician gives a forbearing a illustrative, it is accompanied with a prescription to top up after the illustration is gone. Sometimes accessible samples are used by physicians to help patients who cannot afford medications. But the availability of drug samples is not unceasingly in the cards and, when patients return for refills and the samples they need are missing from a practice, either because the anaesthetize representative didn’t leave enough or stopped distributing them altogether, patients who were started on brand name drugs in sample form are port side paying the price when they have to fill a prescription.

Researchers were surprised to boon that, throughout the study, Medicaid patients were generally prescribed generic drugs, equivalent with the availability of branded samples. Surprising, Miller said, because at the forthwith of the library, Medicaid didn’t have a formulary, so all drugs in support of Medicaid patients, branded or generic, were only $1.

Bromide possible explanation, Miller said, is that because Medicaid patients rarely receive samples, doctors’ prescribing decisions since these patients were based purely on what dose they thought was best and not on what samples happened to be available in the closet.

“In terms of safety and effectiveness, doctors have the most gen about older drugs because they have been used suitable years and are often more conscious,” Miller said. “Sometimes, doctors don’t stumble upon that a new panacea has consequential side-effects until it has been used in a on the loose platoon of people or in support of a prolonged time.” In modern years, Miller added, the Food and Benumb Administration has issued warnings approximately some new drugs and a infrequent procure been pulled from the market, showing how a promising new drug can later be discovered harmful.

“Physicians and medical organizations need to ask themselves if samples are doing more harm than good,” Miller added. “While doctors strength intend to daily help someone by handing them a free trial, in the long run, it could rate them more. And removing samples from a preparation can help doctors focus on which medication is best for a dogged, rather than which medication happens to be available for unencumbered. Patients who want to preserve money should ask their doctor if an effective generic medication is available since their condition a substitute alternatively of taking a sample. In the long run, the generic drug hand down in all likelihood save them more.”

People ubiquitously are understanding the grief of a worldwide slump. Our cells, too, are under continual assault from stress.

Hidden from sight, our cells battle challenges such as their setting, bacteria, viruses, too much or too little oxygen, and physiological stressors. Molecular systems protect cells under lay into, but those systems can break out of down, especially with age.

To wagerer understand how cells are protected from stress and impairment, a span led by Northwestern University researchers studied the any way you look at it become operative of resveratrol, a healthy chemical found in red wine, on kind cells in tissue culture.

The findings may aide explain what happens in neurodegenerative diseases, which are grow older-related, when cell barrier fails, proteins misfold, lots of destruction accumulates and the arrangement falls separately from.

The researchers discovered a untrodden molecular relationship critical to keeping cells tonic across a long extent of time: a protein called SIRT1, important for caloric restriction and lifespan and activated by resveratrol, regulates heat shock factor 1 (HSF1), keeping it active. HSF1 in upset senses the presence of damaged proteins in the stall and elevates the symbol of molecular chaperones to up a cell’s proteins in a folded, practicable land. Regulation of this pathway has a direct beneficial effect to cells, the research shows.

This situation of SIRT1 — a protein already of faithful interest to pharmaceutical companies — was not previously known. The results will be published in the Feb. 20 issue of the quarterly Science.

“When SIRT1 levels are high, you are in a high-shield mode,” said Richard I. Morimoto, Bill and Gayle Cook Professor of Biochemistry, Molecular Biology and Cell Biology in Northwestern’s Weinberg College of Arts and Sciences. He led the delving team.

“Ironically, triggering the stress response and perhaps maintaining the stall in a protective affirm upward of a long epoch of time can mind cells thriving,” said Morimoto. “The room is protected against an growth of bill when HSF1 is more active.”

SIRT1 levels decrease as humans age, Morimoto explains. Cells can’t reply to stress as likely. This decrease in SIRT1 may help explain why protein misfolding diseases, such as Alzheimer’s, Parkinson’s, Huntington’s and full-grown-onset diabetes, are diseases of aging.

“We now have a authoritative way to think about addressing neurodegenerative diseases,” said Morimoto. “We get identified a pathway that can be manipulated to alter lifespan. Discovering this unusual basis for therapeutics is very inspiring.”
