Research solves mystery of memory and mood Posted: 31 May 2015 06:11 PM PDT Researchers have identified two types of stem cells in the hippocampus, a region of the brain crucial for learning and memory.

Preoperative statins reduce mortality in coronary artery bypass graft surgery Posted: 31 May 2015 06:11 PM PDT New research is exploring the protective effect of various heart medications that patients are taking before undergoing coronary artery bypass graft surgery and concludes that statins reduce the risk of death by two thirds, or 67 percent, while no consistent effects were seen for other medications.

American surgery patients: More pain medication, yet more pain Posted: 31 May 2015 06:11 PM PDT New research shows that American patients undergoing orthopedic surgery receive more treatments for pain and that their experience of pain differs in some aspects to orthopedic patients internationally.

No reason for laughing gas to be withdrawn from operating theaters Posted: 31 May 2015 06:11 PM PDT A new article concludes that there is 'no clinically relevant evidence for the withdrawal of nitrous oxide.'

Discovery could improve radiotherapy for wide range of cancers Posted: 31 May 2015 06:10 PM PDT Scientists have discovered how giving a class of drugs called AKT inhibitors in combination with radiotherapy might boost its effectiveness across a wide range of cancers, according to a new study.

High cost of healthcare for UK military amputees from Afghan conflict Posted: 31 May 2015 06:10 PM PDT Researchers have calculated that £288 million is the cost of lifetime care for amputee veterans from the Afghanistan conflict.

Immunotherapy drug improves survival for common form of lung cancer Posted: 31 May 2015 03:11 PM PDT In a head-to-head clinical trial comparing standard chemotherapy with the immunotherapy drug nivolumab, researchers found that people with squamous-non-small cell lung cancer who received nivolumab lived, on average, 3.2 months longer than those receiving chemotherapy. Squamous non-small cell lung cancer accounts for 25 to 30 percent of all lung malignancies.

Contact lens wearers: Eyes may get more infections because their 'microbiomes' have changed Posted: 31 May 2015 11:10 AM PDT Using high-precision genetic tests to differentiate the thousands of bacteria that make up the human microbiome, researchers suggest that they have found a possible — and potentially surprising — root cause of the increased frequency of certain eye infections among contact lens wearers.

Possible new combination chemotherapy for patients with advanced prostate cancer Posted: 31 May 2015 07:00 AM PDT A role for combination therapy using two or more chemotherapy agents at the same time has not been well studied. This week, however, results of a clinical trial may change the perspective on a role for combination chemotherapy in advanced disease.

Risks of whole brain radiation therapy added to radiosurgery outweigh benefits for patients with limited brain metastases Posted: 31 May 2015 07:00 AM PDT Whole Brain Radiation Therapy (WBRT) is associated with significantly worse cognitive function than radiosurgery, and should no longer be used in the adjuvant setting after radiosurgery to treat cancer patients with brain metastases, according to a large study.

Immunotherapy combo increases progression-free survival in advanced melanoma patients Posted: 31 May 2015 07:00 AM PDT Treating advanced melanoma patients with either a combination of the immunotherapy drugs nivolumab and ipilimumab or nivolumab alone significantly increases progression-free survival over using ipilimumab alone, according to researchers.

Gene therapy, surgery could mean eight more months for sickest brain cancer patients Posted: 31 May 2015 07:00 AM PDT As the most malignant of primary brain cancers, glioblastomas are frustratingly difficult to treat. Surgery is often risky and cannot remove all of the tumor, and chemotherapy eventually becomes ineffective for most patients. Median survival is around 15 months for patients with this tumor, and the quality of life in the last five months is often quite poor.
