Objective: Chloride is the major plasma anion. There are several methods available for the determination of serum chloride levels. Unfortunately these methods are sometimes not available in the urgent setting where values are needed. Here we describe...

introduction: erythrocyte sedimentation rate (esr) remains as one of the most reliable tests in clinical practices. yet its use is time consuming and requires a large blood sample. the aim of this study was assessing a faster and reliable method of esr estimation. methods: an esr estimation method was described and performed on 108 patients using capillary tube (micro esr) and capillary periphe...

purpose: to compare the tono-pen and schiotz tonometers in measurement of intraocular pressure (iop) in patients with primary congenital glaucoma. methods: this study was conducted on 38 eyes of 20 patients with primary congenital glaucoma. all measurements were performed under general anesthesia. one minute after receiving halothane 3% iop was determined by tono-pen and then by schiotz tonomet...

Introduction Evaluation of accuracy, precision, and trending ability of cardiac index (CI) measurements using the Aesculon™ bioimpedance electrical cardiometry (Aesc) compared to the continuous pulmonary artery thermodilution catheter (PAC) technique before, during, and after cardiac surgery. Methods A prospective observational study with fifty patients with ASA 3-4. At six time points (T), m...

This paper documents the research towards the development of a system based on Artificial Neural Networks to predict muscle force patterns of an athlete during cycling. Two independent inverse problems must be solved for the force estimation: evaluation of the kinematic model and evaluation of the forces distribution along the limb. By solving repeatedly the two inverse problems for different s...

The article by Bar et al (March 2003)1 reports an evaluation of the Watch PAT100 (WP100) device (Itamar Medical; Caesarea, Israel) for the diagnosis of obstructive sleep apnea. The manner in which the authors have presented their data does not adequately evaluate the accuracy of the WP100 device. The authors have used correlation and Bland-Altman plots to compare calculations of the apnea hypop...

OBJECTIVE To develop an artificial neural network (ANN)-equation to estimate maximal oxygen uptake (VO(2max)) from 20m shuttle run test (20 mSRT) performance (stage), sex, age, weight, and height in young persons. METHODS The 20 mSRT was performed by 193 (122 boys and 71 girls) adolescents aged 13-19 years. All the adolescents wore a portable gas analyzer to measure VO(2) and heart rate durin...

Fig. 2 Representative T1-w GRE and IR-FLASH images (a), correlation of MRI-measured IRE zones with ablated necrosis area (♦,T1-w GREmeasured IRE zone; ○, IR-FLASH measured IRE zone) (b) and Bland-Altman plot comparing T1-w GRE and IR-FLASH with ablated necrotic area (c and d, respectively). Early visualization of the irreversible electroporation ablated tissue margin by contrast enhanced imagin...

PURPOSE To assess the validity of central corneal thickness (CCT) and corrected intraocular pressure (IOP) values obtained by tono-pachymetry in non-surgical and post-photorefractive keratectomy (PRK) eyes. METHODS For the study, 108 young healthy participants and 108 patients who had PRK were enrolled. Measurements were randomly performed by tono-pachymetry, ultrasonic (US) pachymetry, and G...
