DMARDs Tied to Lower Dementia Risk in RA

https://goo.gl/Y5vk7o

UK researchers have analyzed rheumatoid arthritis (RA) patients from the UK Clinical Practice Research Database and shown that chronic conventional DMARD (cDMARD) use was associated with 40% lower risk of dementia (nearly 50% with methotrexate use).

They compared 3876 cDMARD users to 1938 nonusers among incident RA and found a reduced risk of dementia (hazard ratio: 0.60; 95% confidence interval: 0.42-0.85). The effect was strongest in methotrexate users (hazard ratio: 0.52; 95% confidence interval; 0.34-0.82).

These results suggest a new potential therapeutic role for DMARDs and the possible contribution of inflammation on dementia.


Existing drug effective at preventing onset of type 1 diabetes in 60% of patients

The method for discovering this treatment is as interesting as what the drug does....

A drug commonly used to control high blood pressure may also help prevent the onset of type 1 diabetes in up to 60 percent of those at risk for the disease.

"This is the first personalized treatment for type 1 diabetes prevention," said Aaron Michels, MD, a researcher at the Barbara Davis Center for Childhood Diabetes and associate professor of medicine at CU Anschutz. "We made this discovery using a supercomputer, on the lab bench, in mice and in humans."

The drug, methyldopa, has been used for over 50 years to treat high blood pressure in pregnant women and children. It is on the World Health Organization's list of essential drugs.

But like many drugs used for one condition, Michels and his colleagues found it useful for something totally unrelated.

Some 60 percent of people at risk of getting type 1 diabetes possess the DQ8 molecule which significantly increases the chance of getting the disease. The researchers believed that if they could block specifically the DQ8 molecule they could also block the onset of the disease.

"All drugs have off-target effects. If you take too much acetaminophen you can hurt your liver," Michels said. "We took every FDA approved small molecule drug and analyzed HLA-DQ8 binding through a supercomputer. We searched a thousand orientations for each drug to identify those that would fit within the DQ8 molecule binding groove."

After running thousands of drugs through the supercomputer, they found that methyldopa not only blocked DQ8, but it didn't harm the immune function of other cells like many immunosuppressant drugs do.


How can I lower my insulin levels?

https://goo.gl/bS7NSm

Ideally, there is a balance between blood sugar and insulin in the body. Some instances exist, however, where insulin does not work as well as it should, forcing the body to produce an excessive amount of insulin. This is known as insulin resistance, which is a risk factor for developing diabetes, as well as a primary feature of type 2 diabetes.

A person who is insulin resistant and wants to maintain a healthy weight and body may need to control their insulin levels.

Many of the steps associated with improved insulin resistance are already considered to be healthful habits that many people would do well to adopt anyway. We take a look at some of them in this article.

1. Eating foods that keep blood sugar levels low

Often, the foods that keep blood sugar levels low are also foods that will help keep insulin levels low.

Some foods are known to maintain a slower, steady need for insulin instead of causing sudden spikes. These are known as low glycemic index foods and are preferred sources of carbohydrates.

2. Avoiding foods that cause insulin spikes

Just as there are foods that are beneficial to lowering insulin levels, there are some that cause spikes. These include high-sugar foods, such as candies and chocolates.

Dried fruits and energy drinks can also be sources of sugar that lead to insulin spikes. Avoiding these foods can help keep insulin levels down.

3. Following a low-carbohydrate diet

According to an article in the journal Diabesity, eating a low-carbohydrate diet can help reduce a person's insulin levels as well as promote weight loss and lower blood pressure.

There are several types of low-carbohydrate diets a person can choose from, depending on how many carbs they are allowed to consume. Examples include the Atkins, South Beach, and the Mediterranean diet, which favors carbohydrates that come from healthful, fiber-rich sources, such as wheat and beans. It also includes fruits, vegetables, nuts, olive oil, and fish.


Strong Eczema Response to JAK Inhibitor

https://goo.gl/iWvPHH

Patients with moderate or severe atopic dermatitis (AD) had as much as 74% improvement in disease status with the oral Janus kinase (JAK) inhibitor upadacitinib, a randomized trial showed.

After 16 weeks, patients randomized to one of three doses of upadacitinib had a mean improvement of 39.4% to 74.4% in the Eczema Area and Severity Index (EASI), as compared with 23% in the placebo group. Half of the patients had 90% improvement in the index (EASI 90) after 16 weeks. The same proportion met the criteria for almost/completely clear by investigator global assessment criteria (IGA 0/1).

Upadacitinib is a once-daily, oral JAK1-selective inhibitor under evaluation for several inflammatory diseases, Guttman-Yassky noted. The FDA recently granted breakthrough therapy status for the drug.

Adverse events, serious adverse events, and severe adverse events occurred in a similar proportion of placebo- and upadacitinib-treated patients. Rates of discontinuation because of adverse events were 5.0% with placebo and 2.4-9.5% with upadacitinib. The most common adverse events in all groups (including placebo) were upper respiratory tract infection, worsening of AD, and acne.


Those scented products you love? NOAA study finds they can cause air pollution

https://goo.gl/Fph7PC

Emissions from volatile chemical products like perfumes, paints and other scented consumer items now rival vehicles as a pollution source in greater Los Angeles, according to a surprising new NOAA-led study.

Even though 15 times more petroleum is consumed as fuel than is used as ingredients in industrial and consumer products, the amount of chemical vapors emitted to the atmosphere in scented products is roughly the same, said lead author Brian McDonald, a CIRESoffsite link scientist working at NOAA.

A paper presenting these study findings was published today in Science.offsite link

The chemical  vapors, known as volatile organic compounds or VOCs, react with sunlight to form ozone pollution, and, as this study finds, also react with other chemicals in the atmosphere to form fine particulates in the air.

“As the transportation sector gets cleaner, these other sources of VOCs become more and more important,” McDonald said. “A lot of stuff we use in our everyday lives can impact air pollution.”


New and Proposed Changes to Medicare Part D

https://goo.gl/emBD9e

Late last week, Congress passed and the President signed a sweeping spending bill that will fund the government through March 23 and raise the spending caps imposed by the Budget Control Act of 2011 for two years, paving the way for a longer-term spending agreement. The legislation – the Bipartisan Budget Act of 2018 (BBA of 2018) – also contains a number of health care provisions important to people with Medicare and their families, including changes to Medicare Part D prescription drug coverage that will close the donut hole in 2019.

Just days later, on February 12, the White House released President Trump’s fiscal year (FY) 2019 budget request to Congress, which also includes several proposals related to Medicare, including changes to Part D drug coverage and Part B drug reimbursement.

The BBA of 2018 also addressed critical “extenders” – creating permanent fixes for the therapy cap and extending for two years funding for critical Medicare outreach and assistance activities. But the bill also included increases in premiums for some higher-income beneficiaries, further means testing the program. Both the legislation and the budget request allow for more flexibility for private Medicare Advantage plans and target Medicare Part D for a number of changes.

new brief from the Kaiser Family Foundations focuses on the Part D related changes and their potential impact – including, in the President’s request, the imposition of an out-of-pocket cap on Part D, changes to how the donut hole is calculated that will increase the amount of time people spend in it, and allowing the administration to shift medications from Part B to Part D.


Aging area near Traverse City joins “village movement” to stay at home

https://goo.gl/qk11dC

Decades ago, before “aging in place” became a movement, a small group of residents in rural Leelanau County began a conversation.

That led to a plan: a grassroots network of volunteers and basic services for the elderly so they could remain in their homes as long as possible.

More than 20 years later, Pauline McClure, 91, is still in her home in Northport, a pretty beachfront town popular with retirees north of Traverse City. That’s in no small part due to ShareCare of Leelanau Inc., the nonprofit that grew from those discussions.

“It’s almost a lifesaver,” McClure said.

McClure was a ShareCare charter member in 1994. She’s served on its board, as board vice president and has given her time driving members to dental or medical appointments, visiting the lonely or taking meals to those in need.

Now she’s on the receiving end.

A couple years ago, she fell and bruised her left leg, which led to infection and surgery. After her release from the hospital, ShareCare’s nurse came to her home to change her dressing. Members brought meals. McClure now depends on a volunteer driver from the organization to take her to doctor appointments in Traverse City 30 miles away.

“When we were younger, we said, ‘We’ll never need that.’ Well, now I’m the one having to ask for help once in a while,” McClure said.

There’s another name for what ShareCare does ‒ what’s become known nationally as the “village movement” that now counts 230 like-minded programs across the United States, with another 130 in development. Officially the Village to Village Network, it traces its origins to a Boston nonprofit called Beacon Hill Village that opened in 2002 – eight years after network member ShareCare was founded on similar principles.

Other Michigan nonprofits are exploring establishing something similar, though none has taken it as far as ShareCare.


Ice Age Mammoth Footprints Show How Juveniles Took Care Of The Elderly In Ancient Times

https://goo.gl/cjaKBT

As explained in a report from the Daily Mail, a team of researchers from the University of Oregon examined a total of 117 mammoth prints dating back to approximately 43,000 years ago, with these fossilized footprints first spotted in 2014, and excavated some time later. In 2017, the Oregon Bureau of Land Management gave study lead author and University of Oregon professor Greg Retallack and his colleagues permission to return to the area. This was when the researchers’ interest was piqued by a collection of about 20 Ice Age mammoth footprints that hinted at some interesting behavior from the prehistoric elephants.

After analyzing the footprints, the researchers concluded that they might have belonged to Columbian mammoths that were, during those times, quite plentiful in certain parts of the present-day United States. A look at the 20 recently spotted footprints suggested that some of the prints came from a wounded, possibly elderly mammoth, with the other prints coming from younger mammoths.

“These prints were especially close together, and those on the right were more deeply impressed than those on the left, as if an adult mammoth had been limping,” explained Retallack.


Brain Chemical Blamed For Old Age Mental Decline Could Hold Key to Its Reversal

https://goo.gl/Z1yEmw

In both C. elegans and humans, the chemical kynurenic acid (KYNA) accumulates with age. As it builds up, KYNA interferes with the activity of glutamate, a brain chemical essential for learning and memory. In humans, it has previously been linked to neurodegenerative disorders, including Alzheimer’s and Parkinson’s disease.
In the study published Jan. 31, 2018, in Genes and Development, researchers looked at the effect of KYNA on the worms’ ability to learn an association between a neutral smell and food.

The researchers found that by keeping KYNA levels low throughout the worm’s life, they could prevent the onset of age-related decline – the worms kept learning. In older worms already impaired, lowering KYNA levels could counteract the impairments – raising hope that interventions later in life may be effective in reversing neurological decline.

The reason that KYNA increases with age is still a mystery, but the new study offers an intriguing hint, by linking KYNA buildup in aging worms to elevated levels of insulin, a hormone that controls blood sugar in both worms and humans. In contrast, earlier experiments by Ashrafi’s team had found that fasting, which has been linked to longevity, reduced levels of KYNA in worms and improved learning and memory.

Ashrafi thinks that KYNA is the linchpin through which fasting makes the brain better at learning, while aging makes it worse. “These are two sides of the same coin,” he said.
