Dramatic improvement in the "Bulk" hyperpolarization of Xe via spin exchange optical pumping probed using in situ low-field NMR.

We report on hyperpolarization of quadrupolar (I=3/2) Xe via spin-exchange optical pumping. Observations of the Xe polarization dynamics via in situ low-field NMR show that the estimated alkali-metal/Xe spin-exchange rates can be large enough to compete with Xe spin relaxation. Xe polarization up to 7.

The Importance of Inclusion for Cardiovascular Health Promotion Programs in Delaware.

Individuals with disabilities experience greater rates of cardiovascular disease than individuals without disabilities. This increase can be attributed to decreased levels of physical activity, poor eating habits, and increased levels of diabetes, smoking, and obesity. Individuals with disabilities are often excluded from surveillance, treatment, and prevention efforts.

The Effectiveness of the Snug Vest on Stereotypic Behaviors in Children Diagnosed With an Autism Spectrum Disorder.

Various reviews of the effects of sensory integration therapy (SIT) have concluded that such interventions fail to reduce stereotypy. However, a new, and as yet untested, SIT iteration, an inflatable wearable vest known as the Snug Vest purports to decrease such repetitive behavior. In the current study, three children who emitted different forms of stereotypy participated in an alternating treatments design in which each participant wore a fully inflated vest and either a fully deflated vest or no vest.

Effect of changing indications and techniques on total hip resurfacing.

Recently, improved metal-on-metal bearing technology has led to the reemergence of resurfacing as a reasonable option for total hip arthroplasty. During the course of a prospective multicenter FDA-IDE evaluation of metal-on-metal total hip resurfacings, we modified our indications and emphasized surgical technique where the femoral surface area was small due to femoral cysts and small component size. We assessed the influence of these changes on complication rates in the first cohort of 292 patients and the second of 724, and then compared these outcomes in the second cohort with historical reports of resurfacing.

Use of a magnet to retrieve a broken scalpel blade.

The retrieval of metallic foreign bodies, such as screws, drill bits, needles, and scalpel blades, from the surgical wound during orthopaedic surgery is often a time-consuming procedure. The extra time and dissection may result in increased morbidity. We report a case during a hip arthroplasty in which a broken surgical blade could not be located with surgical dissection even with the aid of an image intensifier.

The use of erythropoietin in the management of Jehovah's Witnesses who have revision total hip arthroplasty.

Five Jehovah's Witnesses (one man and four women) were managed with revision total hip arthroplasty. The average age of the patients at the time of the index operation was 66.4 years (range, fifty-eight to seventy-eight years).

Early failure of short-segment pedicle instrumentation for thoracolumbar fractures. A preliminary report.

The results after treatment of fifty-two lumbar and thoracolumbar fractures with Cotrel-Dubousset instrumentation were reviewed as part of an ongoing study. Nineteen patients (average duration of follow-up, fifteen months) had been managed with short-segment pedicle-screw instrumentation. This preliminary report outlines the complications and pitfalls identified during the initial healing phase in this subgroup of patients.
