Certain medications commonly used to treat heartburn, acid reflux, and ulcers can have damaging effects on the kidneys.

Worrying traces of resistant bacteria in air

Posted: 18 Nov 2016 05:55 AM PST

Polluted city air has now been identified as a possible means of transmission for resistant bacteria. Researchers have shown that air samples from Beijing contain DNA from genes that make bacteria resistant to the most powerful antibiotics we have.

Older first-time mothers are also more likely to live longer

Posted: 17 Nov 2016 05:50 PM PST

The average age of a woman giving birth for the first time has risen dramatically in the United States over the past 40 years, driven by factors like education or career. A new study found that women choosing to become first-time mothers later in life may increase their chances of living into their 90s.

Reducing salt intake may help protect kidney patients’ heart and kidney health

New research indicates that reducing sodium intake may provide kidney and heart benefits for patients with chronic kidney disease (CKD).

Insights on the link between kidney damage and cognitive impairment

Posted: 17 Nov 2016 05:49 PM PST

People with kidney disease are at high risk of cognitive impairment, but the nature of this relationship remains uncertain.

A new method to create kidney organoids from patient cells may provide insights into how kidney diseases arise and how they should be treated.

135,000 alcohol-related cancer deaths predicted by 2035

Posted: 17 Nov 2016 05:47 PM PST

Alcohol will cause around 135,000 cancer deaths over the next 20 years and will cost the NHS an estimated £2 billion in treatments, according to estimates from a new report.

Why raising good cholesterol may not always protect against heart disease

Posted: 17 Nov 2016 12:22 PM PST

Good cholesterol is well associated with lower cardiovascular disease risk, but just raising high-density lipoprotein (HDL) levels have produced disappointing results in recent clinical trials. A new study may explain why: HDL actually increases the inflammatory response of immune cells called macrophages, potentially counteracting its well-established anti-inflammatory effect in various other cell types.

Shared epigenetic changes underlie different types of autism

Posted: 17 Nov 2016 12:18 PM PST

Those with both rare and common types of autism spectrum disorder share a similar set of epigenetic modifications in the brain, according to a study. More than 68% of individuals with different types of autism spectrum disorder show evidence of the same pattern of a chemical modification of the protein scaffold around which DNA wraps. The findings suggest that a single global epigenetic pattern affecting shared molecular pathways in the brain could underlie diverse manifestations of this psychiatric disease.

How the heart turns into bone

Posted: 17 Nov 2016 12:18 PM PST

Connective tissue cells in the heart turn into bone-producing cells in response to injury, researchers have found. The discovery helps explain why some people who survive heart damage develop abnormal calcium deposits--the main component of bone--in the valves or walls of the heart. The researchers also show that heart calcification can be prevented in mice by blocking an enzyme that regulates bone mineralization with small molecules.

Estimating survival in patients with lung cancer, brain metastases

Posted: 17 Nov 2016 12:13 PM PST

A new article updates a tool to estimate survival in patients with lung cancer and brain metastases. Lung cancer is a leading cause of death in the United States and around the world. A frequent and serious consequence of the disease is metastasis to the brain.

Epilepsy: why do seizures sometimes continue after surgery?

Posted: 17 Nov 2016 07:44 AM PST

The potential reasons why many patients with severe epilepsy still continue to experience seizures even after surgery have been outlined in a new report. Epilepsy continues to be a serious health problem and is the most common serious neurological disorder. Medically intractable temporal lobe epilepsy (TLE) remains the most frequent neurosurgically treated epilepsy disorder.

Fear of gaining weight may influence contraception choices

Posted: 17 Nov 2016 07:17 AM PST
