Comparing the different sets of item-diagnostic criteria of the Coma Recovery Scale-Revised (CRS-R): a measurement-based approach driven by Rasch analysis.

Objectives: (1) to replicate the assessment of the internal construct validity of the Coma Recovery Scale-Revised (CRS-R) within the Rasch Measurement Theory framework using a larger multicenter sample size; (2) to compare the different sets of item diagnostic criteria against the measurement ruler constructed from Rasch analysis to understand how those criteria relate to the overall level of persons' consciousness.

Design: Multicenter retrospective study.

Setting: Seven centers.

Surgical treatment of refractory low back pain using implanted BurstDR spinal cord stimulation (SCS) in a cohort of patients without options for corrective surgery: Findings and results from the DISTINCT study, a prospective randomized multi-center-controlled trial.

Background: Low back pain (LBP) is a highly prevalent, disabling condition affecting millions of people. Patients with an identifiable anatomic pain generator and resulting neuropathic lower extremity symptoms often undergo spine surgery, but many patients lack identifiable and/or surgically corrective pathology. Nonoperative treatment options often fail to provide sustained relief.

Mixed Tin Valence in the Tin(II/IV)-Nitridophosphate SnPN.

SnPN combines the structural versatility of nitridophosphates and Sn within one compound. It was synthesized as dark gray powder in a high-pressure high-temperature reaction at 800 °C and 6 GPa from SnN and PN. The crystal structure was elucidated from single-crystal diffraction data (space group C2/m (no.

In Ischemic Heart Disease, Reduced Sensitivity to Pressure at the Sternum Accompanies Lower Mortality after Five Years: Evidence from a Randomized Controlled Trial.

Autonomic nervous system dysfunction (ANSD) is associated with negative prognosis of ischemic heart disease (IHD). Elevated periosteal pressure sensitivity (PPS) at the sternum relates to ANSD and sympathetic hyperactivity. Two previous observational case-control studies of the effect of reduction of PPS suggested lower all-cause mortality from IHD and stroke.

Measuring child and adolescent well-being in Denmark: Validation and norming of the Danish KIDSCREEN-10 child/adolescent version in a national representative sample of school pupils in grades five through eight.

KIDSCREEN-10 is a generic instrument for measuring global health-related quality of life among 8-18-year-old children and adolescents. This study examines the criterion-related construct validity and psychometric properties of the Danish language version of the KIDSCREEN-10 using Rasch models. A further aim was to construct Danish norms based on the resulting person parameter estimates from the Rasch models.
