Forsyth research explains why popular antacids may increase chance of bone fractures

New study provides best explanation for side effect of prescription and over-the-counter heartburn medications used by 100 million Americans

2015-03-26
(Press-News.org) CAMBRIDGE, Mass., March 26, 2015 - Newly published research from the Forsyth Institute details a discovery explaining why the 100 million Americans estimated to be taking prescription and over-the-counter antacid and heartburn medications may be at an increased risk of bone fractures.

The new report from Forsyth, published in the March issue of the prestigious medical research journal PLOS Genetics, explains that stomach acid in the gastrointestinal tract plays an important role in helping the intestines absorb and transfer calcium to the skeletal system. While the introduction of proton pump inhibitor-based antacids reduces the level of acidity in the stomach to bring relief to patients, the reduction also interrupts and even stops the gut from absorbing much needed calcium.

The connection between proton pump inhibitors and bone fractures has been well established, with the Food and Drug Administration in 2010 requiring a warning label placed on all product packaging. Other research has indicated these medications may block the absorption of important nutrients, but until this study it was not known how or why this was happening in the body.

"The regulation of bone mass by the gastrointestinal tract represents a remarkable example of an unexpected and important relationship between these two systems that is only now becoming fully appreciated," said Dr. Ricardo Battaglino of the Forsyth Institute. "It could help us better understand and find new ways to treat common clinical conditions that currently require medications which have been linked to weakened bones, such as popular antacids."

Over-the-counter and prescription antacids are used by 100 million Americans to treat heartburn and related conditions. It is the third highest selling drug category with $14 billion in annual sales according to the American Academy of Family Physicians. Fractures at the hip, wrist, arm, ribs and even vertebrae - especially in individuals aged 50 and older - can permanently impair quality of life and result in an expensive drain on the American healthcare system.

Nerve cells borrow a trick from their synapses to dispose of garbage

2015-03-26
Genetic defects affecting tiny channels in human nerve cells lead to several neurological diseases that result from aberrant nerve transmission, such as episodic ataxia, absence epilepsy, and migraines. These disorders have also been associated with neurodegeneration, but it has been less clear why this should be. The transmission of nerve impulses requires the perfect orchestration of a series of complex cellular events in a matter of fractions of a second. The membrane that surrounds a nerve cell is normally electrically polarized, but a nerve impulse triggers a Mexican ...

Ebola whole virus vaccine shown effective, safe in primates

2015-03-26
MADISON, Wis. -- An Ebola whole virus vaccine, constructed using a novel experimental platform, has been shown to effectively protect monkeys exposed to the often fatal virus. The vaccine, described today (March 26, 2015) in the journal Science, was developed by a group led by Yoshihiro Kawaoka, a University of Wisconsin-Madison expert on avian influenza, Ebola and other viruses of medical importance. It differs from other Ebola vaccines because as an inactivated whole virus vaccine, it primes the host immune system with the full complement of Ebola viral proteins and ...

To survive, a parasite mixes and matches its disguises, study suggests

To survive, a parasite mixes and matches its disguises, study suggests
2015-03-26
Orchestrated costume changes make it possible for certain nasty microbes to outsmart the immune system, which would otherwise recognize them by the telltale proteins they wear. By taking the first detailed look at how one such parasite periodically assumes a new protein disguise during a long-term infection, new research at Rockefeller University challenges many assumptions about one of the best-known examples of this strategy, called antigenic variation, in the parasite that causes African sleeping sickness. For research published on March 27 in Science, a team at Rockefeller ...

Antarctic ice shelves rapidly thinning

2015-03-26
A new study led by Scripps Institution of Oceanography at UC San Diego researchers has revealed that the thickness of Antarctica's floating ice shelves has recently decreased by as much as 18 percent in certain areas over nearly two decades, providing new insights on how the Antarctic ice sheet is responding to climate change. Data from nearly two decades of satellite missions have shown that the ice volume decline is accelerating, according to a study published on March 26, 2015, in the journal Science and supported by NASA. Scripps graduate student Fernando Paolo, Scripps ...

Calcium channels play a role in neuronal homeostasis and elimination of toxic buildup of proteins

2015-03-26
HOUSTON - (March 26, 2015) - Taking out the garbage is a crucial step in housecleaning. Similarly, autophagy is the body's first-line of defense against the buildup up of toxic substances, degrading old organelles and proteins to provide new substrates and building blocks. In this way, autophagy prevents the buildup of "garbage" that can result in destruction of neurons and cause neurologic diseases. A forward genetic screen in Drosophila melanogaster (fruit flies) identified mutant copies, or alleles, of a gene called cacophony associated with defects in autophagy ...

What if the severity of our seasonal influenza were related to our genetic background?

2015-03-26
While most of us recover from influenza after a week, it can be a very severe disease, and even fatal in rare cases, with no reason for physicians to have expected such an outcome. By analysing the genome of a little girl who contracted a severe form of influenza at the age of two and a half years, researchers at the Laboratory of Human Genetics of Infectious Diseases (a joint French-American international laboratory), which brings together researchers from Inserm, Paris Descartes University, and physicians from the Paris public hospitals (AP-HP; Necker Hospital for Sick ...

New study shows bacteria can use magnetic particles to create a 'natural battery'

2015-03-26
New research shows bacteria can use tiny magnetic particles to effectively create a 'natural battery.' According to work published in journal Science on 27 March, the bacteria can load electrons onto and discharge electrons from microscopic particles of magnetite. This discovery holds out the potential of using this mechanism to help clean up environmental pollution, and other bioengineering applications. The European Association of Geochemistry is highlighting this work as especially interesting. According to study leader Dr James Byrne (Tübingen): "The geochemistry ...

Intergenerational transmission of abuse and neglect more complicated than previously believed

2015-03-26
A study led by Cathy Spatz Widom, Distinguished Professor of Psychology at John Jay College, found that offspring of parents with histories of child abuse and neglect are themselves at risk for childhood neglect and sexual abuse but not physical abuse. Titled "Intergenerational Transmission of Child Abuse and Neglect: Real or Detection Bias?" the study's findings were reported in the March 27 issue of the journal Science. As part of a prospective longitudinal study, Widom followed a large group of children with documented cases of childhood abuse and neglect and a demographically ...

International collaboration essential in fight against rabies, new study finds

2015-03-26
A new study, published today in the journal PloS Neglected Tropical Diseases has given new insights into the spread of rabies in the Middle East, showing that the deadly disease regularly moves between countries in the region. The international team of researchers including scientists from the University of Surrey and the Animal and Plant Health Agency, have mapped the spread of rabies in the region to help inform control methods. Previous studies have demonstrated that rabies, a fatal disease transmitted by the bite or scratch from an infected animal, still kills approximately ...

Galaxy clusters collide; dark matter still a mystery

2015-03-26
Dark matter is one of science's great mysteries. It makes up an enormous amount matter in the universe, it is invisible, and it does not correspond to anything in the realm of our experience. Different theories compete for an explanation, but so far none of them has prevailed. In a collaborative study between École Polytechnique Fédérale de Lausanne (EPFL) and the University of Edinburgh, scientists have studied how dark matter behaves when galaxy clusters collide with each other over billions of years. Published in Science, their findings challenge at least ...
