Use of anti-depressants during pregnancy not linked with increased risk of stillbirth, infant death, study suggests Posted: 01 Jan 2013 03:20 PM PST In a study that included nearly 30,000 women from Nordic countries who had filled a selective serotonin reuptake inhibitor prescription during pregnancy, researchers found no significant association between use of these medications during pregnancy and risk of stillbirth, neonatal death, or postneonatal death, after accounting for factors including maternal psychiatric disease.

Fructose has different effect than glucose on brain regions that regulate appetite Posted: 01 Jan 2013 03:20 PM PST In a study examining possible factors regarding the associations between fructose consumption and weight gain, brain magnetic resonance imaging of study participants indicated that ingestion of glucose but not fructose reduced cerebral blood flow and activity in brain regions that regulate appetite, and ingestion of glucose but not fructose produced increased ratings of satiety and fullness.

Best to be overweight, but not obese? Higher levels of obesity associated with increased risk of death Posted: 01 Jan 2013 03:20 PM PST In an analysis of nearly 100 studies that included approximately 3 million adults, relative to normal weight, overall obesity (combining all grades) and higher levels of obesity were both associated with a significantly higher all-cause risk of death, while overweight was associated with significantly lower all-cause mortality.

Real-world patient survival with defibrillators matches trial expectations Posted: 01 Jan 2013 03:20 PM PST Patients who received an implantable heart defibrillator in everyday practice had survival benefits on par with those who received the same devices in carefully controlled clinical trials, according to a new study that highlights the value of defibrillators in typical medical settings.

The science of neurosurgical practice: Experts discuss importance of quality improvement, clinical research, patient care Posted: 01 Jan 2013 08:48 AM PST Neurosurgical practitioners discuss specialty's commitment to quality improvement and improving long-term patient health, as well as the need for more data collection and "real-time" information to develop databases of medical disorders and treatment options.

Second impact syndrome in a high school football player: Researchers use imaging findings to chronicle new details Posted: 01 Jan 2013 08:48 AM PST Image series and other data help researchers shed new light on the rare and devastating condition of second impact syndrome.
