PET is a quantitative imaging technique and therefore requires a common quality control (QC)/quality assurance (QA) procedure to maintain the accuracy and precision of quantitation. Repeatability and reproducibility are two essential re- quirements for any quantitative measurement and/or im- aging biomarker. Repeatability relates to the uncertainty in obtaining the same result in the same patient when he or she is examined more than once on the same

3. Preliminary X-ray CT investigation to link Hounsfield unit measurements with the International System of Units (SI). (PubMed)

Preliminary X-ray CT investigation to link Hounsfield unit measurements with the International System of Units (SI). This paper lays the groundwork for linking Hounsfield unit measurements to the International System of Units (SI), ultimately enabling traceable measurements across X-ray CT (XCT) machines. We do this by characterizing a material basis that may be used in XCT reconstruction giving linear combinations of concentrations of chemical elements (in the SI units of mol/m3) which may (...) the number of Hounsfield units per (mole per cubic meter) at each tube voltage for each of 13 chemical elements. We defined a corresponding matrix in units we call molar Hounsfield unit (HU) potency, the difference in HU values that an added mole per cubic meter in a given voxel would add to the measured HU value. We built a matrix of molar potencies for each chemical element and tube voltage and performed a singular value decomposition (SVD) on these to formulate our material basis. We determined

4. Measuring Frailty in Administrative Claims Data: Comparative Performance of Four Claims-Based Frailty Measures in the United States Medicare Data. (PubMed)

Measuring Frailty in Administrative Claims Data: Comparative Performance of Four Claims-Based Frailty Measures in the United States Medicare Data. There has been increasing effort to measure frailty in the United States Medicare data. The performance of claims-based frailty measures has not been compared.This cross-sectional study included 3,097 community-dwelling fee-for-service Medicare beneficiaries (mean age 75.6 years) who participated in the 2008 Health and Retirement Study examination (...) . Four claims-based frailty measures developed by Davidoff, Faurot, Segal, and Kim were compared against frailty phenotype, a deficit-accumulation frailty index (FI), and activities-of-daily living (ADL) dependence using Spearman correlation coefficients and C-statistics.Claims-based frailty measures were positively associated with frailty phenotype (prevalence in ≤10th vs >90th percentile: 8.0% vs 41.3% for Davidoff; 5.9% vs 53.1% for Faurot; 3.3% vs 48.0% for Segal; 2.9% vs 51.0% for Kim) and FI

7. Evaluating bone remodeling by measuring Hounsfield units in a rabbit model of rhinosinusitis: is it superior to measuring bone thickness? (PubMed)

Evaluating bone remodeling by measuring Hounsfield units in a rabbit model of rhinosinusitis: is it superior to measuring bone thickness? The traditional method of evaluating bone remodeling in chronic rhinosinusitis is to measure bone thickness. The objective of this study was to determine the feasibility of measuring the computed tomography (CT) value in Hounsfield units (HU) as an method and explore whether it is superior to measuring bone thickness.The study was a prospective animal trial (...) . Twenty normal rabbits were included in the control group, and 60 rabbit models were inoculated with Staphylococcus aureus to induce rhinosinusitis. The rabbit models were divided into 3 groups according to the time of infection. All animals were euthanized after the CT exam. The samples were scored based on mucus and bone changes. The rabbits were divided into negative and positive groups according to whether bone remodeling was observed. We obtained diagnostic threshold values by measuring the bone

Validation of inertial measurement units with optical tracking system in patients operated with Total hip arthroplasty. Patient reported outcome measurement (PROMs) will not capture in detail the functional joint motion before and after total hip arthroplasty (THA). Therefore, methods more specifically aimed to analyse joint movements may be of interest. An analysis method that addresses these issues should be readily accessible and easy to use especially if applied to large groups of patients (...) , who you want to study both before and after a surgical intervention such as THA. Our aim was to evaluate the accuracy of inertial measurement units (IMU) by comparison with an optical tracking system (OTS) to record pelvic tilt, hip and knee flexion in patients who had undergone THA.49 subjects, 25 males 24 females, mean age of 73 years (range 51-80) with THA participated.

Association of usual 24-h sodium excretion with measures of adiposity among adults in the United States: NHANES, 2014. Both excessive sodium intake and obesity are risk factors for hypertension and cardiovascular disease. The association between sodium intake and obesity is unclear, with few studies assessing sodium intake using 24-h urine collection.Our objective was to assess the association between usual 24-h sodium excretion and measures of adiposity among US adults.Cross-sectional data (...) were analyzed from a sample of 730 nonpregnant participants aged 20-69 y who provided up to 2 complete 24-h urine specimens in the NHANES 2014 and had data on overweight or obesity [body mass index (kg/m2) ≥25] and central adiposity [waist circumference (WC): >88 cm for women, >102 cm for men].

Effects on balance skills and patient compliance of biofeedback training with inertial measurement units and exergaming in subacute stroke: a pilot randomized controlled trial. Stroke patients have reduced balance and postural control that limits their activities of daily living and participation in social life. Recently, many exergaming systems based on video-biofeedback have been developed for balance training in neurological conditions, however their efficacy remains to be proven. The aim (...) of this study was to investigate the effects on balance skills and patient compliance of biofeedback training based on inertial measurement units and exergaming in subacute stroke. The enrolled subjects were randomized into two groups: subjects allocated to the experimental group performed 10 sessions of biofeedback balance training using inertial sensors, whereas subjects allocated to the control group performed 10 sessions of conventional balance training. All subjects were assessed at T0 (pre-treatment

May Measurement Month 2017: an analysis of blood pressure screening results from the United Arab Emirates-Northern Africa and Middle East. Elevated blood pressure (BP) is a growing burden worldwide, leading to over 10 million deaths each year. May Measurement Month (MMM) is a global initiative aimed at raising awareness of high BP and to act as a temporary solution to the lack of screening programmes worldwide. United Arab Emirates has a young population, but cardiovascular disease (CVD (...) ) is the commonest cause of death (40%). Myocardial infarction and stroke occurs at least a decade earlier than in western countries. Previous screening in our young population showed that 85% of the population had at least one CVD risk factor and about 62% of them were unaware of it. An opportunistic cross-sectional survey of volunteers aged ≥18 was carried out in May 2017.
