PCMH Breaking Ground on New Dialysis Center 11/9/11 - KOSA |

KOSA
The Pecos County Memorial Hospital will break ground on a new dialysis center tomorrow. The new center will hold double the patients from 32 to 64, so they don't have to travel to Odessa to get their treatments. PCMH has been working on the new

Tear drops as useful as blood for monitoring blood glucose levels (in rabbits). |
|
|
|
EurekAlert: Tests of their approach in laboratory rabbits, used as surrogates for humans in such experiments, showed that levels of glucose in tears track the amounts of glucose in the blood. "Thus, it may be possible to measure tear glucose levels multiple times per day to monitor blood glucose changes without the potential pain from the repeated invasive blood drawing method," say the researchers.

Extra-carotid to internal carotid artery bypass surgery of limited value after ministroke. |
|
|
|
EurekAlert: Patients with thickening and blockage of the internal carotid artery (supplies blood to the brain) and hemodynamic cerebral ischemia (insufficient blood flow to the brain, sub-type of stroke) who had a surgical procedure performed to improve blood flow in the artery did not have a reduced rate of stroke after 2 years compared to similar patients who received medical therapy alone, according to a study in the Nov. 9 issue of JAMA.

Potassium channels in the hypothalamus linked to blood glucose control. |
|
|
|
EurekAlert: The current Einstein study, involving people, was aimed at resolving this controversy. Ten nondiabetic subjects were given oral diazoxide, a drug that activates potassium channels in the hypothalamus. (The drug is not used to treat diabetes.) Hormone secretion by the pancreas was controlled to ensure that any change in sugar production would only have occurred through the drug's effect on the brain. After the researchers administered the drug, blood tests revealed that patients' livers were producing significantly less glucose than before. Dr. Hawkins and her team then repeated this in rats, again giving diazoxide orally, achieving similar results. They confirmed that sufficient amounts of diazoxide crossed the blood-brain barrier to affect potassium channels in the hypothalamus. Additional experiments confirmed that diazoxide was working through the brain. Specifically, the researchers were able to completely block the effects of diazoxide by infusing a specific potassium channel blocker directly into the brain.

Most women with lupus can have successful pregnancy outcomes |
|
|
|
EurekAlert: Of the 333 women with lupus studied, 63 had poor outcomes. Ten percent of mothers experienced preeclampsia, a serious complication characterized by the onset of high blood pressure and appearance of protein in the urine. Ten percent experienced mild or moderate flares at 20 weeks and eight percent experienced flares at 32 weeks. Nineteen women experienced death of the fetus and 30 women delivered before 36 weeks or had newborns of small gestational size – smaller in size than normal for the baby's sex and gestational age, commonly defined as a weight below the 10th percentile for gestational age.
