Comparison of cement pressurisation in flanged and unflanged acetabular cups
Published: 3 February 2012
Background
This biomechanical study examined difference in cement pressures generated by flanged and unflanged acetabular cups in hip arthroplasty.
Method
Using a model acetabulum, cement was inserted and pressurised followed by cup insertion and pressurisation. Pressures were recorded using transducers in the acetabulum. We compared Charnley Ogee (flanged), Exeter contemporary (flanged) and Exeter low profile (unflanged) cups using Simplex and CMW1 cements in turn.
Results
Using Simplex, Charnley Ogee cup generated highest initial peak pressure and overall mean pressure.
Kick insomnia
Getting too little sleep? Over time, sleep deprivation will take a toll on your immune system and make you more vulnerable to colds and flu. People who get less than six hours of sleep a night have a 50 percent higher risk of viral infections, according to researchers. Too little sleep reduces white blood cell activity, which increases your chances of getting sick. Insomnia also increases your risk for diabetes, cancer, depression and anxiety, heart disease and high blood pressure, and obesity. Sleep deprivation is becoming commonplace with up to 40 percent of Americans suffering symptoms of insomnia within a given year, and 10-15 percent dealing with chronic insomnia, according to the National Center for Sleep Disorders Research at the National Institutes of Health.

Treating Diabetes, Depression Together May Make Sense
Patients with depression and type 2 diabetes showed more improvement when they received simultaneous treatment for both conditions, researchers report.
Their 12-week study of 180 patients found that nearly 61 percent of those who received integrated care combined with a brief program to help them adhere to their medication regimens achieved improved blood sugar test results, and almost 59 percent had a reduction in depression symptoms.
Among patients who received usual primary care for the two conditions, nearly 36 percent had improved blood sugar test results and about 31 percent had a reduction in depression symptoms, said the researchers at the Perelman School of Medicine at the University of Pennsylvania.
The study appears in the January/February issue of the journal Annals of Family Medicine.
There is a link between depression and diabetes, the researchers noted.
