Sleep apnea gets worse in the winter

Reuters – 13 hrs ago NEW YORK (Reuters Health) - The breathing problems caused by sleep apnea appear to worsen during the colder months of the year, according to a new study from Brazil.

People with the common sleep disorder stop breathing multiple times throughout the night, each bout lasting from seconds to minutes.

Jerome Dempsey, who studies breathing problems at the University of Wisconsin and was not involved in the new study, said it makes sense that airway infections and weather would have an effect on sleep apnea.

But the changes in sleep apnea across seasons are small, Dempsey added, and the study does not prove that winter weather in itself makes sleep apnea worse.

According to the National Heart, Lung, and Blood Institute, one in 10 adults over age 65 has sleep apnea.

Seasonal changes in weight and allergies can affect sleep apnea, and the Brazilian researchers, led by Cristiane Maria Cassol at Universidade Federal do Rio Grande do Sul, wanted to see if weather changes might also have any impact on the disorder.

They used data from patients who came in for testing at a sleep clinic on how many times their sleep was disturbed by breaks in breathing. The study included one night of sleep for more than 7,500 patients over a 10-year period.

The researchers then compared the severity of the patients' apnea to the weather conditions at the time, including humidity, temperature and air pollution.

Patients who came in during the colder months had more nighttime breaks in breathing than those who sought treatment during the warmer months. For instance, during the winter, patients stopped breathing an average of 18 times per hour, compared to 15 times an hour during the summer.

Similarly, the sleep clinic was more likely to see the most severe cases - people who stopped breathing more than 30 times an hour - in the colder months.

About 34 percent of patients who came in during cold weather had severe apnea, while 28 percent of patients during warm weather had severe apnea.

The team found that certain weather conditions - high atmospheric pressure and humidity and high levels of the air pollutant carbon monoxide - were tied to worse cases of apnea.

But the study could not determine whether it's the weather that's responsible for the more severe sleep apneas.

The researchers write in their report, published in the journal Chest, that more severe apnea in the winter "can be due to several circumstances, including winter-related upper-airway problems that intensify the severity of (sleep apnea) symptoms."

Another possibility is that wood burning to heat homes during the winter can cause irritation in the airways and aggravate sleep apnea.

"There are so many things that affect sleep apnea, including the decision of when to come visit" a sleep clinic, Dempsey told Reuters Health.

In other words, it might not be the weather, but the time of year that makes it more convenient for patients to take the time to seek treatment.

Dempsey said researchers would have to follow patients for at least a year and observe how their conditions change in order to say whether sleep apnea really does worsen in the winter.

While winter-related conditions such as colds or allergies might intensify sleep apnea, Dempsey said the biggest risk factor is obesity.

Half of all heart patients make medication errors

Reuters – 11 hrs ago NEW YORK (Reuters Health) - Half of all heart patients made at least one medication-related mistake after leaving the hospital, and guidance from a pharmacist didn't seem to reduce those errors, in a new study.

Consequences of mistakes - such as forgetting to take certain drugs or taking the wrong dose - can range from side effects like constipation to more serious drops in blood pressure. Two percent of errors were life-threatening.

Hospitals involved in the study were already taking steps to prevent medication mistakes in addition to the extra pharmacist intervention, said Dr. Sunil Kripalani, the study's lead author from the Vanderbilt University Medical Center in Nashville, Tennessee.

"We were surprised to see that in spite of these efforts that 50 percent (of patients) were still having these medication errors," he told Reuters Health.

Although the pharmacist visits didn't help the average patient, he added, certain ones seemed to benefit - such as patients who were on multiple drugs or had trouble understanding health information.

As for traditionally lower-risk patients, he said other strategies to prevent errors may be needed.

ONE-ON-ONE MEETINGS

For their study, Kripalani and his fellow researchers followed patients who had been hospitalized for heart conditions at Vanderbilt University Hospital and Brigham and Women's Hospital in Boston.

Half of the patients were randomly assigned to attend two visits with a pharmacist, who looked at which medications patients were taking and instructed them on what to do once they left the hospital to manage their prescriptions and reduce side effects.

The patients also received tools, such as a medication chart and pillbox, to use at home.

After leaving the hospital, the patients received a phone call within a few days from one of the study's coordinators who was able to identify medication-related problems over the phone. If any were found, a pharmacist made a follow-up call.

The other heart patients did not receive any special treatment outside of normal hospital procedure, which is for a nurse or doctor to spend a few minutes with patients before they leave the hospital to discuss their medications.

One month later, 432 out of the 851 patients had made at least one harmful or potentially-harmful medication error, including missing doses, taking the incorrect dose, stopping a drug too early or continuing it for too long.

Just under one-quarter of those errors were judged to be serious and about two percent were life-threatening. And there was no difference in the number of errors made by patients who did or didn't get extra pharmacist advice.

One limitation, the researchers note in their Annals of Internal Medicine report, is that not all patients in the intervention group had two pharmacist visits or a follow-up call as intended. It's also unclear whether the findings would apply to patients being treated for other, non-heart conditions.

KEEP A LIST

Kevin Boesen, director of the Medication Management Center at the University of Arizona College of Pharmacy in Tucson, told Reuters Health he's not surprised that many people are confused after leaving the hospital.

"To me, I think (the finding) highlights the challenge for the transition from hospital to home," he said.

Boesen added that it's important for patients to meet with their regular pharmacist and primary care doctor after they get out of the hospital or fill a prescription somewhere else.

"I think there is the assumption that when a patient goes to a pharmacy the pharmacist will have a list of all the medication they're on," he said. But that's not always the case.

A key safety step patients can take, Boesen and Kripalani agreed, is to keep track of all of the drugs they're taking and carry a list.

"The single most important thing patients and families can do to promote safety with their medications is to always keep a medication list with them," Kripalani said. That list should include drug doses and patients' reason for taking each medication, he added.

"If a patient simply carries that medication list, so everyone is working off of one list, that definitely helps," said Boesen.

'Ted' Joke Offends ALS Patients

A punch line from the movie "Ted" has people with Lou Gehrig's disease crying foul.

"From one man to another, I hope you get Lou Gehrig's disease," Mark Wahlberg's "John" says to his foul-mouthed teddy bear friend -- a quip some patients say crossed a line.

"I didn't expect to go to a movie and sit with an audience laughing at the expense of people with ALS," said Randy Pipkin, who was diagnosed with Lou Gehrig's disease in 2005. "I think the message this film sends out is a huge slap in the face to people dying from this horrific disease."

Lou Gehrig's disease progressively robs people of their ability to move, speak, eat and breathe. There is no cure.

"This line from Ted is something that never should have been said much less survived the editing process for a major movie release especially as a punch line for a comedy," Jeff Lester, an ALS patient from Lebanon, Mo., wrote in an open letter to Wahlberg and "Ted" writer Seth MacFarlane posted on Facebook.

Puerto Rico sees sharp spike in dengue cases

The number of detected dengue cases is running at above-average levels as Puerto Rico enters the peak season for the painful disease.

The territory's Health Secretary Lorenzo Gonzalez says 111 cases were reported the first week of June and 117 cases the previous week. Eight cases of the more-severe hemorrhagic form have been confirmed, though no one has died.

A U.S. Centers for Disease Control report shows new infections running at a pace that has marked past epidemics. Dengue cases usually peak in early October.

Gonzalez said late Tuesday that detected cases may be rising because of new courses to help doctors identify symptoms.

The mosquito-borne virus causes fever, severe headaches and extreme joint and muscle pain.

Dengue claimed a record 31 lives in Puerto Rico during a 2010 epidemic.

India to give free generic drugs to hundreds of millions

Reuters – 6 hrs ago MUMBAI (Reuters) - India has put in place a $5.4 billion policy to provide free medicine to its people, a decision that could change the lives of hundreds of millions, but a ban on branded drugs stands to cut Big Pharma out of the windfall.

From city hospitals to tiny rural clinics, India's public doctors will soon be able to prescribe free generic drugs to all comers, vastly expanding access to medicine in a country where public spending on health was just $4.50 per person last year.

The plan was quietly adopted last year but not publicized. Initial funding has been allocated in recent weeks, officials said.

Under the plan, doctors will be limited to a generics-only drug list and face punishment for prescribing branded medicines, a major disadvantage for pharmaceutical giants in one of the world's fastest-growing drug markets.

"Without a doubt, it is a considerable blow to an already beleaguered industry, recently the subject of several disadvantageous decisions in India," said KPMG partner Chris Stirling, who is European head of Chemicals and Pharmaceuticals.

"Pharmaceutical firms will likely rethink their emerging markets strategies carefully to take account of this development, and any similar copycat moves across other geographies," he added.

But the initiative would overhaul a system where healthcare is often a luxury and private clinics account for four times as much spending as state hospitals, despite 40 percent of the people living below the poverty line, or $1.25 a day or less.

Within five years, up to half of India's 1.2 billion people are likely to take advantage of the scheme, the government says. Others are likely to continue visiting private hospitals and clinics, where the scheme will not operate.

"The policy of the government is to promote greater and rational use of generic medicines that are of standard quality," said L.C. Goyal, additional secretary at India's Ministry of Health and Family Welfare and a key proponent of the policy.

"They are much, much cheaper than the branded ones."

Global drugmakers like Pfizer, GlaxoSmithKline and Merck will be hit. They spend billions of dollars a year researching new treatments and target huge growth for branded medicine in emerging economies such as India, where generics account for around 90 percent of drug sales by value, far more than in developed countries.

U.S.-based Abbott Laboratories, which bought an Indian generics maker in 2010, is the biggest seller of drugs, both branded and generic, in India, followed by GlaxoSmithKline.

BIG PHARMA BLUES

In March, India granted its first ever compulsory license, allowing a domestic drugmaker to manufacture a copy-cat version of Nexavar, a cancer drug developed by Germany's Bayer, unnerving foreign drugmakers that fear a lack of intellectual property protection in emerging markets.

That enabled India's Natco Pharma to sell its generic version of Nexavar at 8,800 rupees ($160) per monthly dose, a fraction of the 280,000 rupees Bayer's version cost.

In another blow to Big Pharma's emerging market ambitions, China recently overhauled regulations to grant authorities the power to allow domestic drugmakers to produce cheap copies of medicines protected by patents.

Emerging markets are on track to make up 28 percent of global pharmaceuticals sales by 2015, up from 12 percent in 2005, according to IMS Health, a healthcare information and services company.

Most sales in emerging markets come from branded generics, which are off-patent drugs priced at a premium to those made by local manufacturers.

The Organisation of Pharmaceutical Producers of India (OPPI), a lobby group for multinational drugmakers in the country, argues that the price of drugs is just one factor in access to healthcare and that the scheme need not be detrimental to manufacturers of branded drugs.

"I think this will hasten overall growth of the pharmaceutical industry, as poor patients who could not afford will now have access to essential medicines," said Tapan Ray, director general of OPPI.

About 600 billion rupees ($11 billion) in drugs are sold each year in India, or 482 billion at wholesale. Drugs covered under the new policy account for about 60 percent of existing sales, or 290 billion rupees at wholesale cost.

The government's annual cost is likely to be lower due to bulk purchasing and because patients at private clinics would still pay for their own drugs. States will pay for 25 percent of the free drugs and the central government will cover the rest.

Under various existing programs, around 250 million people, or less than a quarter of India's population, now receive free medicines, according to the health ministry.

India's new policy, to be implemented by the end of 2012 and rolled out nationwide within two years, is expected to provide 52 percent of the population with free drugs by April 2017, at a cumulative cost of 300 billion rupees ($5.4 billion).

That requires a major funding ramp-up from a deficit-strapped government. The scheme has been granted just 1 billion rupees thus far from central government coffers.

STRICT INSTRUCTIONS

Public doctors will be able to spend 5 percent of the budget, equivalent to around $50 million a year, on drugs outside of the government's list, on branded drugs or on medicines that are not on the list. Beyond that, they can be punished, said Goyal, the health ministry official.

"If doctors are found to be prescribing medicines which are not on the list, or which are branded, then disciplinary action will be initiated," he said.

Free medicine is just one solution to better healthcare in India, where just getting to a state clinic can require a long journey.

Swapnil Yadav, who runs a clinic in Ambegaon, a village 170 km (105 miles) southeast of Mumbai, said India should set up free drug retailers instead of government clinics.

"Patients can approach a private clinic and then get free medicines from government-run medicine shops," he said.

The free generics scheme, which mirrors policies in the states of Tamil Nadu and Rajasthan, is expected to be fully operational by the time voters go to the polls for the 2014 general election, when the populist Congress party will seek a third straight victory.

Indian makers of generics such as Dr Reddy's and Cipla are best placed to benefit.

"The move will please the generics manufacturers who stand to gain substantially in competing for contracts," said KPMG's Stirling.
