Sleep loss influences cholesterol metabolism, study finds

Lack of sleep has previously been found to impact the activation of the immune system, inflammation, carbohydrate metabolism and the hormones that regulate appetite. Now University of Helsinki researchers have found that sleep loss also influences cholesterol metabolism.

Cancer survivors at risk of death after organ transplant

People who had cancer before receiving an organ transplant were more likely to die of any cause, die of cancer or develop a new cancer than organ recipients who did not previously have cancer, a new paper has found. However, the increased risk is less than that reported in some previous studies.

Under-expressed miR-9 gene may contribute to schizophrenia risk

By turning skin cells into brain neurons, researchers at the Icahn School of Medicine at Mount Sinai have identified that certain tiny molecules aiding in gene expression, known as microRNAs (miRNAs), are under-expressed in the brains of the 14 schizophrenia patients they studied. Their findings, published online today in the journal Cell Reports, show that one of these molecules, a miRNA known as miR-9, is a risk factor that controls the activity of hundreds of genes.

Unmet nursing care may contribute to racial/ethnic differences in AMI readmissions

Why are black older adults at higher risk of repeat hospital admission after a heart attack? Treatment at hospitals with higher rates of missed nursing care may be a contributing factor, reports a study in the May issue of Medical Care.

Wellderly study finds link between cognitive decline genes and healthy aging

An eight-year-long accrual and analysis of the whole genome sequences of healthy elderly people, or "Wellderly," has revealed a higher-than-normal presence of genetic variants offering protection from cognitive decline, researchers from the Scripps Translational Science Institute (STSI) reported today in the journal Cell.

Assessing body composition may help predict cardiovascular and total mortality

Researchers from the David Geffen School of Medicine at UCLA found that cardiovascular disease patients who have high muscle mass and low fat mass have a lower mortality risk than those with other body compositions. The findings also suggest that regardless of a person's level of fat mass, a higher level of muscle mass helps reduce the risk of death.

Study finds low prevalence of vascular risk among Southwest US population

In a newly published, pilot study in the journal Ethnicity & Disease, researchers report a relatively low prevalence of vascular risk among participants of the Southwest Heart Mind Study, especially among those treated for hypertension and hyperlipidemia despite overweight and obesity.

Microtubules affect mechanics of beating heart, study finds

On top of the meaning and mystery that humans heap on the heart, it is first and foremost, a muscle. And one that beats about once a second for a person's entire life, with no rest. Given its vital importance, it's ironic researchers have only recently made direct observations of its subcellular parts in motion.

GSK3β inhibition may be potential therapeutic strategy for treating ACM

Arrhythmogenic cardiomyopathy (ACM) is an inherited heart disease that results from mutations in genes that encode components of the cardiac desmosome, which forms the junction between cardiac muscle and the epithelium. Patients with ACM have an increased risk of sudden death due to the breakdown of the muscle wall of the heart with age.

Pediatric researchers develop minimally invasive techniques to treat plastic bronchitis

Pediatric researchers have devised an innovative, safe and minimally invasive procedure that helps relieve rare but potentially life-threatening airway blockages occurring in children who had surgery for congenital heart defects.

Macrophages play key role in quick tissue repair

While scientists have known for many years that there are cells living in the cavities surrounding various organs such as the heart, lung and liver, their function has remained unknown. A recent Cumming School of Medicine study examined these cells, and discovered they play an integral role in fast tissue repair. The study was published in the journal Cell this month.

Study links duration, timing of sleep to cardiovascular health

No one is telling you what time to go to bed with this, but researchers are making a strong case that the duration and timing of your sleep are closely associated with whether your behavior is heart-healthy.

Researchers use highly accurate biomarker to measure aging in HIV infected patients

Thanks to combination antiretroviral therapies, many people with HIV can expect to live decades after being infected. Yet doctors have observed these patients often show signs of premature aging.

Subtle changes in protein-coding gene may cause different genetic disorders

It has been disorienting to the scientific and medical community as to why different subtle changes in a protein-coding gene causes many different genetic disorders in different patients -- including premature aging, nerve problems, heart problems and muscle problems. no other gene works like this. According to a new study, co-authored by Binghamton University faculty Eric Hoffman, it has to do with cell "commitment."

More cautious blood pressure-lowering strategy may be reasonable for elderly CKD patients

New research indicates that higher systolic blood pressure is linked with poor outcomes in patients with kidney disease, although the association diminishes with advanced age. The findings, which come from a study appearing in an upcoming issue of the Clinical Journal of the American Society of Nephrology (CJASN), provide valuable information concerning patients who are often excluded from blood pressure-lowering clinical trials.

TAVR procedure could provide improved health outcomes for inoperable patients

A novel procedure for heart valve replacement surgery could provide improved health outcomes for patients who cannot have open heart surgery, as well as being a cost effective alternative.

Bosutinib shows 'low' vascular, cardiac event risk profile

Third-generation tyrosine kinase inhibitor study findings suggest that bosutinib is associated with a low risk of vascular and cardiac events in patients undergoing first-line or subsequent treatment for chronic myeloid leukaemia.

SI-2 molecule can inhibit tumor growth in breast cancer mouse model

Cancer cells communicate with their environment through cell molecules that pass on signals to the inside of the cell. The signals help cancer cells multiply and migrate, spreading the disease.

Bacteria-derived gut metabolites can affect brain’s myelin content and induce depression-like symptoms

Specific combinations of gut bacteria produce substances that affect myelin content and cause social avoidance behaviors in mice, according to a study conducted at the Icahn School of Medicine at Mount Sinai and published today in the medical journal eLife. This research suggests that targeting intestinal bacteria, or their metabolites, could be one way to treat debilitating psychiatric disorders and demyelinating diseases, like multiple sclerosis.

Study aims to determine how aches, pains before and after concussion play role in recovery

Athletes who have medical complaints, like aches and pains, that have no known physical cause may take longer to recover after a concussion, according to a study published in the April 20, 2016, online issue of Neurology, the medical journal of the American Academy of Neurology.
