Combination Of PET/CT Tests Can Expedite Diagnosis Of Lung Cancer In A Fast-track Setting

Scientists have found an effective combination of positron emission tomography/computed tomography tests to diagnose lung cancer in a "fast-tracked" outpatient setting. This novel approach to the diagnosis of lung cancer demonstrated a high level of sensitivity (97 percent) and accuracy (82 percent). The fast track model tests patients for lung cancer over the course of one day and could expedite...

Eating Sweets Every Day In Childhood 'Increases Adult Aggression'

Children who eat sweets and chocolates every day are more likely to be violent as adults, according to a new study. Researchers found a higher percentage of adults who were violent at age 34 had eaten sweets every day, compared to those who were non-violent. This link persisted after controlling for other...

Lung Cancer Risk Increases With Expression Of Specific Genes

A recent study determined that variations of specific genetic markers identified in previous research, or SNPs, may indicate a greater lung cancer risk in African Americans than in whites. The genes CHRNA3 and CHRNA5 may contribute to lung cancer risk due directly or through their association with nicotine dependence. Although their presence is less frequent in African-Americans, the risk for lung...

New Approach For The Treatment Of Malignant Brain Tumors

Initial chemotherapy alone after surgery is just as successful as initial radiation therapy for patients from whom a very malignant brain tumor (anaplastic glioma) was removed, a new study has found. With this treatment, the patients survive on average more than 30 months without a recurrence. Patients in primary therapy benefit to the same extent from chemotherapy alone as from radiation...

Oxidized Form Of A Common Vitamin May Bring Relief For Ulcerative Colitis

Here's another reason why you should take your vitamins. A new research report suggests that retinoic acid, the oxidized form of vitamin A, could be a beneficial treatment for people suffering from ulcerative colitis and other irritable bowel diseases. Specifically they found that retinoic acid helps suppress out-of-control inflammation, which is a hallmark of active ulcerative...

Scientists Develop Nasal Spray That Improves Memory

Good news for procrastinating students: a nasal spray developed by scientists promises to give late night cram sessions a major boost, if a good night's sleep follows. Scientists show that a molecule from the body's immune system (interleukin-6) when administered through the nose helps the brain retain emotional and procedural memories during REM...

Smoking During Pregnancy Puts Children At Risk Of Psychotic Symptoms

Mothers who smoke during pregnancy put their children at a higher risk of psychotic behavior, according to a new study. Researchers studied more than 6,000 children aged for psychotic symptoms such as hallucinations and delusions. They found the risk of psychotic symptoms was highest in those children whose mothers smoked most heavily in...

Strategy Outlined For Growing Bioenergy While Protecting Wildlife

Researchers have provided an analysis of the consequences for wildlife of the expanding production of bioenergy. The authors of new study identify harvesting of diverse prairie, which is dominated by perennial plants, as a strategy for production of bioenergy feedstocks that could minimize adverse...

Wrist Fracture Patients Less Likely To Be Evaluated For Osteoporosis

A disconnect between the way wrist-fracture patients and those with a spine or hip fracture are managed and evaluated has been reviewed. The study, conducted in 2007 among 97 percent of the women in Korea, reviewed the incidence of fractures around the hip, spine, and wrist in female patients age 50 and older and the prescription frequencies of bone density scans for osteoporosis, along with the...

Fewer Than 50 Percent Of Men And Women With Depression See A Doctor For Treatment

Fewer than half of men and women in Ontario who may be suffering from depression see a doctor to treat their potentially debilitating condition, according to a new women's health study. What's more, many hospitalized for severe depression fail to see a doctor for follow-up care within 30 days of being discharged, and many head to hospital emergency departments for...

Eat Soybeans To Prevent Diseases, New Research Suggests

Soybeans contain high levels of several health-beneficial compounds including tocopherols, which have antioxidant properties. These molecules can be used in the development of functional foods, which have specific health-beneficial properties and can be used in the treatment or prevention of...
