First time mothers may put themselves and baby at risk by choosing home-birth: Report

A new report suggests that first time mothers who opt for a home birth are almost three times more likely to have a baby who dies or suffers brain damage. It also found that traditional maternity units in hospital are the safest place for women to have their first child.

Cancer medicine component could prevent heart attacks

A substance in medicines for cancer and epilepsy could also prevent heart attacks, according to researchers at the Sahlgrenska Academy at the University of Gothenburg, Sweden, who have been using it to stimulate the body's own defence system against blood clots.

TLRs contribute to brain damage following hypoxia in newborns

Two out of every thousand babies are at risk of brain damage in connection with birth. Researchers at the Sahlgrenska Academy at the University of Gothenburg, Sweden, have identified mechanisms behind these injuries, which could lead to better treatment and a richer life for the infants affected.

Tips for parents to safeguard their children

They say parents know best, but what if you are a new parent who doesn't know it all quite yet? "Unfortunately, babies do not come with a safety manual. Sometimes parents do things that are well-intentioned but can be unsafe for their child," said Mary Evelyn O'Neil, M.D., pediatrician, Wake Forest Baptist Medical Center.

CWRU receives NHLBI grant to study sleep apnea as possible cause of AF

Case Western Reserve University School of Medicine has received a $3.8 million grant from the National Heart, Lung, and Blood Institute (NHLBI) to study sleep apnea as a possible cause of atrial fibrillation (AF), the most commonly diagnosed type of arrhythmia, or irregular heart rhythm.

HRR1 after 6MW test is a strong predictor of clinical worsening in IPAH patients

Heart rate recovery at one minute after a six-minute walking distance (6MWD) test is highly predictive of clinical worsening and time to clinical worsening in patients with idiopathic pulmonary arterial hypertension (IPAH), according to a new study.

Scientists solve mystery behind why people with defective hemoglobin do not contract malaria

Why do people with a hereditary mutation of the red blood pigment hemoglobin not contract severe malaria? Scientists in the group headed by Prof. Michael Lanzer of the Department of Infectious Diseases at Heidelberg University Hospital have now solved this mystery.

Resistance of starved bacteria can be blocked

Many infections, even those caused by antibiotic-sensitive bacteria, resist treatment. This paradox has vexed physicians for decades, and makes some infections impossible to cure.

NewYork-Presbyterian/Columbia opens Center for Acute Respiratory Failure

NewYork-Presbyterian Hospital/Columbia University Medical Center has officially opened the Center for Acute Respiratory Failure, which offers, among other services, expertise in using lung bypass technology to help adult patients whose lungs are rapidly shutting down.

Hemoglobin levels, blood pressure and male gender linked to higher risk of silent strokes in SCA children

Factors such as low hemoglobin levels, increased systolic blood pressure, and male gender are linked to a higher risk of silent cerebral infarcts (SCIs), or silent strokes, in children with sickle cell anemia (SCA), according to results from a large, first-of-its-kind study published online today in Blood, the Journal of the American Society of Hematology (ASH).

Stem cell therapy for heart failure: two studies two successes

The Center for Disease Control and Prevention says that heart failure affects nearly 6 million Americans leading to considerable risk of death, diminished quality of like and recurrent hospitalizations. Heart failure occurs when the heart can no longer pump enough blood to the rest of the body. The most common cause of heart failure is coronary artery disease, which narrows the small blood vessels that supply blood and oxygen to the heart.

Researchers identify hepcidin hormone as potential target for atherosclerosis

Researchers at Emory University School of Medicine have identified hepcidin, a hormone that regulates iron levels in the body, as a potential target for treating atherosclerosis.

Diallyl trisulfide may protect heart after attack

A component of garlic oil may help release protective compounds to the heart after heart attack, during cardiac surgery, or as a treatment for heart failure.

Dipyrone may reduce brain damage after stroke

An older nonsteroidal anti-inflammatory drug (NSAID) called dipyrone may offer a new approach to reducing injury to brain tissue after a stroke, according to a study in the October issue of Neurosurgery, official journal of the Congress of Neurological Surgeons.

Human pluripotent stem cells rely heavily on glycolysis to drive their metabolic activities

Human pluripotent stem cells, which can develop into any cell type in the body, rely heavily on glycolysis, or sugar fermentation, to drive their metabolic activities.

Scarring prevents precipitous decline in heart function after cardiac injury

After a heart attack, the portions of the heart damaged by a lack of oxygen become scar tissue. Researchers have long sought ways to avoid this scarring, which can harden the walls of the heart, lessen its ability to pump blood throughout the body and eventually lead to heart failure. But new research from the University of North Carolina at Chapel Hill School of Medicine shows that interrupting this process can weaken heart function even further.

Low-temperature plasmas can kill bacteria for a week after treatment

University of California, Berkeley, scientists have shown that ionized plasmas like those in neon lights and plasma TVs not only can sterilize water, but make it antimicrobial - able to kill bacteria - for as long as a week after treatment.

New research demonstrates brain's remarkable capacity to repair itself

New research released today demonstrates the brain's remarkable capacity to repair itself. The animal studies, which propose ways to prevent or limit damage after blood and oxygen deprivation and blood clots, were presented at Neuroscience 2011, the Society for Neuroscience's annual meeting and the world's largest source of emerging news about brain science and health.

EPO-secreting engineered vessels could reverse anemia

Patients who rely on recombinant, protein-based drugs must often endure frequent injections, often several times a week, or intravenous therapy. Researchers at Children's Hospital Boston demonstrate the possibility that blood vessels, made from genetically engineered cells, could secrete the drug on demand directly into the bloodstream.
