Study finds iodine deficiency reduces the chance of a woman becoming pregnant by almost 50%

fertility, pregnancy test
Women who are deficient in iodine and trying to get pregnant may have half the chance of conceiving compared to women with healthy iodine levels, according to a recent U.S. study.

Researchers followed more than 500 women trying to conceive over about five years and found that, overall, those with moderate to severe iodine deficiency had 46 percent lower odds, per cycle, of becoming pregnant.

"Our finding that moderate deficiency is associated with difficulty conceiving has important public health implications," said lead study author Dr. James Mills of the Eunice Kennedy Shriver National Institute of Child Health and Human Development in Bethesda, Maryland.

"We were surprised that moderate to severe deficiency was so common and that it reduced the chance of a woman becoming pregnant by almost 50 percent in each menstrual cycle," he told Reuters Health by email.

Comment: Iodine is literally a life-saving and essential nutrient for your brain and body - meaning everyone needs it! Deficiency of iodine in any tissue can cause problems in that area of the body and weaken the immune system. Unfortunately, iodine deficiency is very common now due to its displacement in our bodies by environmental toxins such as bromide, pesticides, and food additives. Iodine researchers have tested thousands around the world with consistent results - about 96% of people test low for iodine.

Top UK doctor warns of antibiotic apocalypse

Antibiotics could soon stop working
Antibiotics are becoming resistant to fatal diseases in a frightening trend which could spark a post-antibiotic apocalypse, top scientists are warning.

Professor Dame Sally Davies, Chief Medical Officer for England, has urged UK patients to stop demanding treatment with antibiotics, or risk condemning the planet to an age of death by preventable disease.

Writing for the Huffington Post, the professor revealed an industry-wide fear of new diseases which are resistant to drugs.

The professor said if diseases accelerate and antibodies fail to work, the world's population could be drastically diminished.

She wrote: "Before these truly revolutionary medical leaps, life was very different. Infections regularly killed or caused significant disabilities, many of the operations we now consider routine did not exist and the powerful drugs we use to treat cancer were unthinkable.

"In particular, I want to share one key statistic-in this time before antibiotics and vaccines, around 40% of deaths were due to infections. Now, that number is just 7%," she added.

Delayed onset muscle soreness and what you can do about it

back pain
The combination of early year resolutions and thinking about shorts and bathing suit weather may be responsible for delayed onset muscle soreness (DOMS) as you boost your exercise program or start a new one.

Research demonstrates exercise does more than tone your muscles and helps you fit into your clothes with greater ease. It also helps you build a neurological system and brain that resists shrinkage as you age, and improves your cognitive abilities.1 A long-term investment in regular exercise helps improve your mood and prevent depression.2

Exercise helps boost your metabolism, helps you to maintain your weight and prevent chronic illnesses, such as cardiovascular disease, Type 2 diabetes and high blood pressure. However, while exercise has a significant number of benefits, those benefits are not permanent.

When you stop exercising the benefits to your muscle strength and tone, neurological protection and metabolic boost slowly recede. While it is common to experience post-exercise muscle soreness after beginning a program when you have not exercised in a while, DOMS can occur even when you've been previously exercising. Knowing what it is, how to avoid it and how to speed up healing may discourage you from giving up your program completely when faced with muscle discomfort and stiffness.

Post-Exercise Muscle Soreness

Muscle stiffness may occur after starting a new exercise program, adding a new exercise to your current program or increasing the intensity and duration of your routine. This stiffness is often accompanied by discomfort, pain and sometimes, cramping.

Public school and ADHD - Why some experts don't believe the diagnosis is real

Franch children ADHD
The documentary Pharmabuse compiles interviews with various medical professions who are speaking out about Attention Deficit Hyperactivity Disorder (ADHD). The film raises a growing concern that schools play an integral role in the hasty over-diagnosis of ADHD in school children.

ADHD: Real or Fake?

Is ADHD an actual illness? Or, is it just a list of behaviors that typically would require extra effort on the part of the adult?

In the opinion of Dr. Peter Breggin, MD, Psychiatrist and author of Talking Back to Ritalin, ADHD is a fictitious disease. He claims that Big Pharma created the disease with the support of a handful of psychologists and psychiatrist. Then, they sold it to the education system and medical community.

Breggin is not alone. Many believe that ADHD is not a legitimate diagnosis. The basis for this opinion is that there is no scientific testing involved in assessing ADHD. No MRI, no blood test, and no other diagnostic tests.

Rejuvenation strategies: How rejuvenation of stem cells could lead to healthier aging

elderly

"Rampant" and "elderly" are words rarely used in the same sentence, unless we are talking of the percentage of people over 65 years old worldwide. Life expectancy has considerably increased, but it is still unknown how many of those years are going to be lived in good health.

As a researcher of blood cancers and aging, I inevitably think about how in the next few decades a very large part of the population will deal with cancer treatments. Are we doing the best to manage the side effects, or even to manage aging itself? Could we accumulate just wisdom, instead of aches and pain?

Scientists discover 10 new viral defense systems in bacteria

VIRAL ATTACK Viruses called phages (shown landing on the surface of a cell in this transmission electron micrograph) can infect and kill bacteria. Scientists have just found a slew of new defense mechanisms that help bacteria resist such assaults.
Since long before it gained fame as a precise gene-editing tool, CRISPR has had another job defending bacteria against viral invaders. And it's far from alone. Ten sets of bacterial genes have similar, newly discovered defense roles, researchers report online January 25 in Science.

The discovery "probably more than doubles the number of immune systems known in bacteria," says Joseph Bondy-Denomy, a microbiologist at the University of California, San Francisco, who wasn't involved in the study.

Bacteria are vulnerable to deadly viruses called phages, which can hijack bacteria's genetic machinery and force them to produce viral DNA instead. Some bacteria protect themselves against phage attacks with a system called CRISPR, which stores pieces of past invaders' DNA so bacteria can recognize and fend off those phages in the future (SN: 4/15/17, p. 22). But only about 40 percent of bacteria have CRISPR, says study coauthor Rotem Sorek, a microbial genomicist at the Weizmann Institute of Science in Rehovot, Israel. That's why he and his colleagues are hunting for other defense mechanisms.

AKT protein is key to the brain's 'memory factory'

Ask a nonscientist what memories are made of and you'll likely conjure images of childhood birthday parties or wedding days. Charles Hoeffer thinks about proteins.

For five years, the assistant professor of integrative physiology at CU Boulder has been working to better understand a protein called AKT, which is ubiquitous in brain tissue and instrumental in enabling the brain to adapt to new experiences and lay down new memories.

Until now, scientists have known very little about what it does in the brain.

But in a new paper funded by the National Institutes of Health, Hoeffer and his co-authors spell it out for the first time, showing that AKT comes in three distinct varieties residing in different kinds of brain cells and affecting brain health in very distinct ways.

The discovery could lead to new, more targeted treatments for everything from glioblastoma-the brain cancer Sen. John McCain has-to Alzheimer's disease and schizophrenia.

"AKT is a central protein that has been implicated in a bevy of neurological diseases yet we know amazingly little about it," Hoeffer said. "Our paper is the first to comprehensively examine what its different forms are doing in the brain and where."

Shooting blanks: The human race could be infertile in 50 years

Are we facing a Spermadeggon?
Modern medicine has long presumed fertility to be the dominion of women, a space ruled by gynaecologists and invasive procedures explained by softly pink pamphlets. But that is only half the story. Possibly even less, according to mounting evidence. Male fertility is dipping, and fast. Sperm may prove to be the greatest casualty of modern life.

Last summer, scientists at the Hebrew University of Jerusalem found that male sperm counts had fallen by almost 60 per cent in 40 years. In what was the largest study of its kind, they analysed data from 43,000 men from North America, Europe, Australia and New Zealand, taking in 185 studies from 1973 to 2011. Its lead author, Dr Hagai Levine, decreed the result an 'urgent wake-up call'.

Sperm studies have historically been piecemeal and played second fiddle to female fertility research, but warning signs have been flashing for years. In 2012 a study of more than 26,000 French men found sperm counts fell by a third between 1989 and 2005. In the UK, a 2007 report published in the Journal of Andrology found that in one British city, sperm counts had declined by 29 per cent in 13 years between 1989 and 2002.

Comment: Infertility is a much bigger issue than people tend to think about it. With all the ways we could potentially destroy ourselves as a race, poisoning ourselves to the point that we're infertile has to be one of the stupidest. See also:

Skip the meds: Montmorency cherry juice as effective at reducing high blood pressure as medication

Montmorency cherries
If you're looking for another reason to drink cherry juice, look no further. A new study from Northumbria University, Newcastle, found that Montmorency cherry juice is just as effective at lowering high blood pressure as medication.

The results of the study, published in the The American Journal of Clinical Nutrition, discovered that men with early hypertension, otherwise known as high blood pressure, reduced their blood pressure by 7 percent after drinking Montmorency cherry concentrate, which is comparable to the effect achieved by drugs.

Comment: Generally speaking, diet and lifestyle changes will go a lot farther in improving one's overall health than medication.

The personality changes came ahead of more obvious behavioural changes linked to Alzheimer's.

Increases in neuroticism may help to predict the onset of Alzheimer's, new research finds.

People who transition from mild cognitive impairment to full-blown Alzheimer's are more likely to show personality changes.

Many people with mild cognitive impairment do not go on to develop dementia.
