Validation and psychometric properties of Chinese version of SF‐36 in patients with hypertension, coronary heart diseases, chronic gastritis and peptic ulcer

Z. Yang, W. Li, X. Tu, W. Tang, more

International Journal of Clinical Practice > 66 > 10 > 991 - 998

Background: The SF‐36 is widely used as a significant health outcome or quality of life indicator and validated in many languages versions including Chinese. But the Chinese version of the SF‐36 (CSF‐36) is rarely used for those patients with hypertension, coronary heart diseases, chronic gastritis and peptic ulcer in China. Therefore, the CSF‐36 needs to be validated in patients with chronic diseases...

Development of real-time assays for impedance-based detection of microbial double-stranded DNA targets: Optimization and data analysis

Andrei L. Ghindilis, Maria W. Smith, Dean S. Messing, Vena N. Haynes, more

Biosensors and Bioelectronics > 2012 > 35 > 1 > 87-93

A real-time, label free assay was developed for microbial detection, utilizing double-stranded DNA targets and employing the next generation of an impedimetric sensor array platform designed by Sharp Laboratories of America (SLA). Real-time curves of the impedimetric signal response were obtained at fixed frequency and voltage for target binding to oligonucleotide probes attached to the sensor array...

A laparoscopic approach reduces short‐term complications and length of stay following ileocolic resection in Crohn’s disease: an analysis of outcomes from the NSQIP database

Y. Lee, F. J. Fleming, A.‐P. Deeb, D. Gunzler, more

Colorectal Disease > 14 > 5 > 572 - 577

Aim Studies to date examining the impact of laparoscopy in resection for Crohn's disease on short‐term morbidity have been limited by small study populations. The aim of this study was to establish the impact of the operative approach (laparoscopic or open) on outcomes after ileocolic resection for Crohn’s disease. Method Ileocolic resections for Crohn’s disease were identified using Current Procedural...

It’s the procedure not the patient: the operative approach is independently associated with an increased risk of complications after rectal prolapse repair

F. J. Fleming, M. J. Kim, D. Gunzler, S. Messing, more

Colorectal Disease > 14 > 3 > 362 - 368

Aim This study compares 30‐day outcomes following rectal prolapse repair, examining potential surgical and patient factors associated with perioperative complications. Method Using the NSQIP database, patients with rectal prolapse were categorized by surgical approach to repair (perineal or abdominal) and abdominal cases were further subdivided by procedure (resection compared with rectopexy alone)...

An improved algorithm for quantifying real-time impedance biosensor signals

Dean S. Messing, Andrey Ghindilis, Kevin Schwarzkopf

2011 Annual International Conference of the IEEE Engineering in Medicine and Biology Society > 2740 - 2744

2011 33rd Annual International Conference of the IEEE Engineering in Medicine and Biology Society

In previously published work [1] we presented a real-time electrochemical impedance biosensor prototype system and a state-space estimation algorithm for signal quantification. Experiments in the interim have revealed some algorithm failure modes which reduced the reliability and repeatability of quantification. The present work describes a related algorithm that introduces constraints based on a...

Impedimetric biosignal analysis and quantification in a real-time biosensor system

D S Messing, A Ghindilis, K Schwarzkopf

2010 Annual International Conference of the IEEE Engineering in Medicine and Biology > 2730 - 2734

2010 32nd Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC 2010)

We describe our real-time, label-free, electrochemical impedance biosensor system with an emphasis on the use of an impedance response signal model to quantify assays. The signal processing for estimating model parameters from noisy data and the quantitative verification against target concentration and affinity are also presented.

Validity and Responsiveness of Generic Preference-based HRQOL Instruments in Chronic Epilepsy

J. T. Langfitt, B. G. Vickrey, M. P. McDermott, S. Messing, more

Quality of Life Research > 2006 > 15 > 5 > 899-914

Generic, preference-based instruments are recommended for assessing health-related quality of life (HRQOL) in cost-utility analyses (CUA). We aimed to determine which instrument is the most appropriate for CUA of epilepsy care, using established psychometric criteria. We compared validity and responsiveness of EQ5D (using both UK and US preferences), visual analog scale (VAS), Health Utilities Index...
