Early Menopause Linked to Brain Aneurysm

Posted:

Early menopause increases risk of brain aneurysm, shows study. A cerebral aneurysm refers to an abnormal bulging of one of the arteries in the brain, which is often only discovered when it ruptures, causing a potentially fatal and/or disabling bleed. Women are more prone to cerebral aneurysms than men. And fluctuations in the female hormone oestrogen have been implicated in the development of aneurysms, the incidence of which, along with cardiovascular disease, ...

Pet dogs can ooze with affection and try to comfort when they see people weeping, states new research. A group of pet dogs was tested with their owners and then strangers, talking, pretending to cry, or humming. Far more dogs come up and touch people when they think they are crying. "The humming was designed to be a relatively novel behaviour, which might be likely to pique the dogs' curiosity. The fact that the dogs differentiated between crying and ...

Bioluminescence Imaging for Hair Regeneration

Cognitive Comparisons' Very Own Complexities

Posted:

Between the Rockies and the Alps, which mountain range is larger? The answer depends on how you compare them. The Alps reach a greater height, and the 10 highest peaks in the Alps are taller in sum than the 10 highest peaks in the Rockies. Then again, the Rockies have three times as many peaks over 4,000 meters, or 13,000 feet, and the main spine of the Rockies runs about five times as far as that of the Alps - meaning the Rockies surely contain a greater volume ...

PAP Therapy Improves Depressive Symptoms in Sleep Apnea Patients

Positive airway pressure (PAP) improves symptoms of depression in patients with obstructive sleep apnea (OSA), reports study. The study looked at 779 patients with OSA and asked them to fill out a standardized PHQ-9 form to assess depressive symptoms, which patients with OSA often have, researchers said. They were assessed again with the PHQ-9 following PAP treatment, and all showed improvement in PHQ-9 scores; however, patients using their PAP devices more ...

Statins Linked to Fatigue

Posted:

Cholesterol-lowering statin drugs cause fatigue upon exertion, say researchers. The researchers suggest that these findings should be taken into account by doctors when weighing risk versus benefit in prescribing statins. Statin drugs are among the best selling and most widely used prescription drugs on the market. Recently, increasing attention has focused on statins'' side effects, particularly their effect on exercise. While some patients have reported fatigue ...

Moderate Drinking may Disrupt Sleep

Posted:

Moderate drinking could disrupt your sleep, say researchers. In a study when college students drank relatively low doses of alcohol, they got less sleep than they did on nights when they didn't drink at all, according to the researchers. While those who drank high doses of alcohol did not experience a reduction in sleep time, they did feel tired the next day. The researchers said the study, which used wristband devices to measure how ...

Novel Treatment Protocol for Kidney Cancer

Posted:

New type of radioimmunotherapy delivers a powerful dose of radiation at the site of cancerous tissue, say researchers. The agent is able to hone in on the disease, called clear cell renal carcinoma, and kill the cancer by delivering radiation directly to it. However, the study shows that its effectiveness could be diminished when used after another anti-cancer therapy. The radioimmunotherapy highlighted in this study is radiolabeled monoclonal antibody girentuximab ...

Three-drug Regimen and Idiopathic Pulmonary Fibrosis

Posted:

Results of a recently published study indicate that the three-drug regimen of prednisone, azathioprine, and N-acetylcysteine may prove to be more harmful than beneficial in patients with idiopathic pulmonary fibrosis. Idiopathic pulmonary fibrosis is a condition where the lungs are damaged and replaced by scar tissue, which impedes adequate air exchange. Lung transplantation is done for some cases. Mild cases are treated either ...

Decoding the DNA of patients with advanced breast cancer has helped scientists spot cancer "signatures" which can help evaluate the benefit of estrogen-lowering therapy for women. Researchers at Washington University School of Medicine in St. Louis uncovered mutations linked to whether or not women respond to aromatase inhibitors, drugs often prescribed to shrink large tumors before surgery. These mutations also correlate with clinical features of breast tumors, ...

Women Must be More Discreet in the Workplace to Get Ahead
