Weighing up blood-thinners: Is warfarin always the best choice?

Posted: 17 Oct 2013 08:12 AM PDT

Patients who are responding below par to the anticoagulant drug warfarin have several options. They can undergo even more blood tests to monitor their response to the different dosages of this medication which is prescribed to prevent strokes, or they could start using one of the newer, yet more expensive, anticoagulants on the market. In the long run, the latter option could actually be more cost-effective and improve a patient's quality of life.

3D images from PET/CT scans help surgeons envision tumors

Posted: 17 Oct 2013 08:11 AM PDT

A hologram-like display of a patient's organs based on molecular PET/CT images helps surgeons plan surgery by allowing them to see detailed anatomical structure, peel away layers of tissue, and see all sides of a tumor, before entering the operating room to excise it.

The pig, the fish and the jellyfish: Tracing nervous disorders in humans

Posted: 17 Oct 2013 07:09 AM PDT

The pig, the jellyfish and the zebrafish have been used to gain a greater understanding of hereditary forms of diseases affecting the nervous system. In this project, the focus was on a specific gene in pigs, SYN1, which encodes the protein synapsin, which is involved in communication between nerve cells. Synapsin almost exclusively occurs in nerve cells in the brain. Parts of the gene can thus be used to control an expression of genes connected to hereditary versions of the nerve disorders.

Toxin-emitting bacteria being evaluated as potential multiple sclerosis trigger

Posted: 17 Oct 2013 06:38 AM PDT

A study of 69,000 Medicare patient records shows that people with spine compression fractures who undergo operations to strengthen back bones with cement survive longer and have shorter overall hospital stays than those who stick with bed rest, pain control and physical therapy.

Lawsuits increasing over skin-related laser surgery performed by non-physicians

Posted: 17 Oct 2013 06:35 AM PDT

A mother's high cholesterol before pregnancy can be passed on to children

Posted: 17 Oct 2013 05:07 AM PDT

More US teens susceptible to HSV-1 infection, a cause of genital herpes

Posted: 17 Oct 2013 05:06 AM PDT

A new study suggests a growing number of US adolescents lack antibodies that may help protect them later in life against an increasingly important cause of genital herpes. The findings show that fewer of today's teens have been exposed in their childhood to herpes simplex virus type 1 (HSV-1), a common cause of cold sores, than US adolescents in previous years. Without these antibodies, today's teens may be more susceptible to genital infections also caused by the virus.

All probiotics are not the same in protecting preemies from common, life-threatening illness

Posted: 17 Oct 2013 05:06 AM PDT

Suffering from breast cancer increases the risk of another tumour by 39%

Posted: 17 Oct 2013 05:02 AM PDT

Women diagnosed with invasive breast cancer are 39% more likely to develop a second cancer in a different part of the body. Such is the conclusion of a recent study. The study suggests that this increased risk could be due to the similar risk factors involved in both cancers, or to the side effects of the treatment received by breast cancer patients.

Cancer cells' communication path blocked

Posted: 17 Oct 2013 05:02 AM PDT

Cancer researchers have discovered the path used by exosomes to enter cancer cells, where they stimulate malignant tumour development. They have also succeeded in blocking the uptake route in experimental model systems, preventing the exosomes from activating cancer cells.

High serum fatty acid protects against brain abnormalities

Posted: 17 Oct 2013 05:01 AM PDT

According to a new study, high long-chain omega-3 polyunsaturated fatty acid content in blood may lower the risk of small brain infarcts and other brain abnormalities in the elderly. In the Cardiovascular Health Study in the USA, 3,660 people aged 65 and older underwent brain scans to detect so called silent brain infarcts, or small lesions in the brain that can cause loss of thinking skills, dementia and stroke. Scans were performed again five years later on 2,313 of the participants.
