To Raise Children In Foreign Lands, Immigrants Overcome Great Odds
A recent surge in immigration rates has led psychologists to study how these families are coping and thriving in their adopted countries. In a special June issue of the Journal of Family Psychology, published by the American Psychological Association, researchers report that close family ties are crucial for immigrants" successful transition to their new country.

Study Highlights Massive Imbalances In Global Fertilizer Use
Synthetic fertilizers have dramatically increased food production worldwide. But the unintended costs to the environment and human health have been substantial. Nitrogen runoff from farms has contaminated surface and groundwater and helped create massive "dead zones" in coastal areas, such as the Gulf of Mexico. And ammonia from fertilized cropland has become a major of air pollution, while emissions of nitrous oxide form a potent greenhouse gas.

Maryland ICU Patients Connected To Remote Critical Care Staff, Improving Qualtiy And Safety
Maryland intensive care patients will now be connected by voice, video and data lines to specialized physicians and nurses at a tertiary care referral center 130 miles away. A year after announcing six, independent Maryland hospitals, with a $3 million grant from CareFirst BlueCross BlueShield, were joining together to provide state-of-the-art critical care to their patients, the first hospital, Calvert Memorial Hospital in Prince Frederick, Md., is fully online with the sophisticated care system.

Using Structural MRI May Help Accurately Diagnose Dementia Patients: Mayo Clinic Study

A new Mayo Clinic study may help physicians differentially diagnose three common neurodegenerative disorders in the future. The study was presented at the Alzheimer"s Association International Conference on Alzheimer"s Disease on July 11 in Vienna. In this study, Mayo Clinic researchers developed a framework for MRI-based differential diagnosis of three common neurodegenerative disorders: Alzheimer"s disease, frontotemporal lobar degeneration, and Lewy body disease using Structural MRI. Currently, examination of the brain at autopsy is the only way to confirm with certainty that a patient had a specific form of dementia. The framework, which is called "STructural Abnormality iNDex" or STAND-Map, shows promise in accurately diagnosing dementia patients while they are alive. The rationale is that if each neurodegenerative disorder can be associated with a unique pattern of atrophy specific on MRI, then it may be possible to differentially diagnose new patients. The study looked at 90 patients from the Mayo Clinic database who were confirmed to have only a single dementia pathology and also underwent an MRI at the time of clinical diagnosis of dementia. Using the STAND-Map framework, researchers predicted an accurate pathological diagnosis 75 to 80 percent of the time. "The STAND-Map framework might have great potential in early diagnosis of dementia patients," says Prashanthi Vemuri, Ph.D., a senior research fellow at the Mayo Clinic aging and dementia imaging research lab and lead author of the study. "The next step would be to test the framework on a larger population to see if we can replicate these results and improve the accuracy level we achieved in this proof of concept study. In turn, this may lead to better treatment options for dementia patients." The senior author of this Mayo Clinic research study is Clifford Jack, M.D. Other members included Kejal Kantarci, M.D.; Matthew L. Senjem; Jeffrey Gunter; Jennifer Whitwell, Ph.D.; Keith Josephs, M.D.; David Knopman, M.D.; Bradley Boeve, M.D.; Tanis Ferman, Ph.D.; Dennis Dickson, M.D.; and Ronald Petersen, M.D., Ph.D. This work was supported in part by National Institutes of Health (NIH) grants, Robert H.
