Risk factors for Alzheimer's disease

Alzheimer's disease has joined cancer at the top of the list of feared diagnoses, and although Alzheimer's does have the potential to devastate millions of patients and families, there are reasons for hope - and possibly opportunities to reduce risk or alter the course of disease progression, according to Keith Black, MD, professor and chair of the Department of Neurosurgery at Cedars-Sinai.

Brain signals in fibromyalgia patients: an interview with Dr. Marco Loggia from Massachusetts General Hospital and Harvard Medical School in Boston

Fibromyalgia patients suffer from a variety of symptoms, including widespread body pain and myofascial tenderness. They are ‘hyperalgesic’, which means that if you give them a stimulus that in healthy subjects is just mildly painful (or even completely innocuous), they may perceive it as excruciatingly painful.

Study explains why south Asians have high susceptibility to developing type 2 diabetes

Lower amounts of brown adipose tissue (BAT, or ‘brown fat’) could help explain why south Asians—who make up a fifth of the world’s population—have an exceptionally high susceptibility to developing metabolic problems such as obesity and type 2 diabetes.

Novel approach confirms dysfunctional energy production in schizophrenia

A method of directly assessing creatine kinase in the brain provides “direct and compelling” evidence for abnormal bioenergetics in the brains of patients with schizophrenia, say the study authors.

FDG-PET parameter predicts locally advanced lung cancer survival

High post-treatment concentrations of a radioactive imaging marker are predictive of worse overall survival from inoperable, locally advanced non-small-cell lung cancer, prospective study findings suggest.

Researchers discover potential method to identify TBI using positron PET scans

Accurately diagnosing traumatic brain injuries (TBI) and concussions is difficult, as standard CT or MRI scans can't see most changes to the brain caused by these injuries.

Shorter sleep duration, poorer sleep quality may impact Alzheimer's disease onset and progression

Poor sleep quality may impact Alzheimer's disease onset and progression. This is according to a new study led by researchers at the Johns Hopkins Bloomberg School of Public Health who examined the association between sleep variables and a biomarker for Alzheimer's disease in older adults.

PET scan shows promise in predicting patients with inoperable lung cancer

Advanced imaging with Positron Emission Tomography (PET) scan shows great promise in predicting which patients with inoperable lung cancer have more aggressive tumors and need additional treatment following standard chemotherapy/radiation therapy, according to new research recently published online in the Journal of Clinical Oncology.

miR-31 in primary tumor cells predicts lymph node metastasis in NSCLC patients

Determining whether a patient's lung cancer has spread to nearby lymph nodes is critical for identifying the most effective therapy, but it usually requires surgery. A new study suggests, however, that measuring levels of a particular molecule in a sample of tumor tissue might accurately answer the question.
