Test-retest reliability of an abbreviated self-report overall health status measure.

STUDY DESIGN Test-retest reliability study. OBJECTIVE To assess test-retest reliability and estimate minimal detectable change of an overall measure and 2 summary measures of patient self-report of health status. BACKGROUND Change in patient self-report of health status is a common outcome measure following rehabilitation. Because collection of health status data takes time and clinicians are required to be productive, selected items from reliable instruments were used to form a new, abbreviated instrument of health status relevant to patients in outpatient rehabilitation. There are no test-retest reliability statistics of these health status measures in this population. METHODS AND MEASURES A convenience sample of 71 patients (mean age +/- SD, 41.9 +/- 17.9 years; age range, 15-83 years; sex, 35% male), with a variety of orthopaedic diagnoses, seeking rehabilitation in 2 outpatient facilities, volunteered. Patients completed health status questionnaires at initial evaluation and at 24 to 72 hours following evaluation. Intraclass correlation coefficients (ICC2.1) were used to estimate test-retest reliability and to estimate measurement error and minimal detectable changes. RESULTS ICCs with a 1-sided lower limit 95% confidence intervals (CI) of the Overall Health Status measure and the Physical and Mental Component Summary measures for patients with chronic symptoms were 0.92 (0.85), 0.82 (0.68), and 0.85 (0.74), respectively. Minimal detectable changes (90% CI) were +/-12 (scale range, 100), +/- 9 (scale range, 60), and +/- 9 (scale range, 60) scale points, respectively, for the same measures. CONCLUSIONS Results support the test-retest reliability of the Overall Health Status measure and summary measures for patients with chronic symptoms and demonstrate ability of the Overall Health Status and Physical Summary Scale measures to detect improvement of patient self-report of health status within the first few days of rehabilitation.
Towards the Experimental Studies of a Web-based Platform for Eco-Tourism

This paper aims at showing the necessity and importance of several experimental studies during the life-cycle of a website. As a case study a web based platform for ecotourism is used. For this purpose, a prototype system, called EcoZante, was developed and different experiments took place. In the early stages of the systems’ life-cycle, an empirical study was conducted with the participation of real users, in order to embrace the main interests of users in the domain. After the implementation of the prototype, two evaluation experiments took place. In the first experiment an expert-based usability evaluation was implemented using a specific framework. Then a summative evaluation with the participation of real users was implemented for almost a year. The results of this evaluation experiments resulted in re-designing the user interface and improving the system. Finally, a comparative evaluation experiment was implemented involving the new improved web-based platform.

Incontinence Outcomes in Women Undergoing Primary and Repeat Midurethral Sling Procedures

OBJECTIVE: To assess stress urinary incontinence (SUI) and other lower urinary tract symptom outcomes in women undergoing repeat midurethral sling procedures compared with those undergoing primary midurethral sling procedures. METHODS: Cure was defined as responses of “not at all” or “somewhat” to both questions of the SUI subscale of the Urogenital Distress Inventory-6; symptom effect was assessed using the Incontinence Impact Questionnaire-7. Multivariable models were created controlling for baseline Medical Epidemiologic and Social Aspects of Aging questionnaire urge score and Urogenital Distress Inventory-6 stress subscale score. RESULTS: One thousand three hundred sixteen patients had charts available for review: 135 of 1,316 (10.2%) had undergone prior midurethral sling procedures; 799 of 1,316 (61%) questionnaires were returned, with 92 from those having undergone prior midurethral sling procedures. Median follow-up time was 36.4 months with a range of 11.4–71.5 months. Cure rates were 71% (95% confidence interval [CI] 67.7–74.3%) in the primary midurethral sling group and 54% (95% CI 43.8–64.2%) in the repeat midurethral sling group (P<.001). Women undergoing repeat midurethral sling procedures experienced significantly greater improvement in symptom-specific quality of life (QOL) compared with those undergoing primary midurethral sling procedures (−28.87±37.6 compared with −18.42±32.73, P=.01). Multivariable analyses revealed that women in the repeat midurethral sling group had increased risk of SUI failure (odds ratio 1.7, 95% CI 1.1–2.8). CONCLUSION: Women undergoing repeat midurethral sling procedures had almost two times the odds of SUI treatment failure but greater improvement in symptom effect on QOL than did those undergoing a primary midurethral sling procedure. This information can help counsel patients regarding their expectations of repeat midurethral sling surgery for recurrent SUI . LEVEL OF EVIDENCE: II
How to do a revision total hip arthroplasty: revision of the acetabulum.

The most common indications for acetabular revision include instability, infection, polyethylene wear, and aseptic loosening1. The prevalence of these conditions remains essentially unchanged despite improved prosthetic component designs and enhanced surgical techniques. A successful acetabular revision must provide intimate contact between the acetabular implant and the host bone, a stable mechanical construct minimizing micromotion to allow bone ingrowth into a cementless acetabular component, and a mechanical construct that distributes the physiologic stresses to the surrounding acetabular bone. Additionally, the acetabular reconstruction must allow appropriate component orientation to minimize the risk of dislocation and reestablish the anatomic hip center to improve the overall joint kinematics. Biologic methods of acetabular reconstruction are advised except in cases of severe bone loss or prior radiation treatment in the hip region, since nonbiologic revisions eventually fail2. Periacetabular bone loss can compromise component fixation, resulting in early loosening of the revised acetabulum. The amount of bone loss undoubtedly influences the ability to obtain initial optimal fixation. The location of remaining supportive bone, however, has a more important role in providing durable fixation than does the quantity of bone loss. Acetabular defect classification systems can be used to predict the extent of bone loss seen intraoperatively and guide subsequent reconstructive options. The three most common classification systems for acetabular defects are the American Academy of Orthopaedic Surgeons (AAOS) classification system described by D'Antonio et al.3 (Table I), the Gross classification system described by Saleh et al.4 (Table II), and the Paprosky classification system5 (Table III). The AAOS classification system identifies the pattern of acetabular bone loss, but does not quantify the size or location of the defect. Despite being the most commonly cited, the AAOS defect classification system does not guide the identification of reconstructive options. The system described by …
Virtual Extracorporeal Circulation Process

Virtual instruments for an extracorporeal circulation (ECC) process were developed to simulate the reactions of a patient to different artificial perfusion conditions. The computer simulation of the patient takes into account the hydraulic, volume, thermal and biochemical phenomena and their interaction with the devices involved in ECC (cannulae dimensions, oxygenator and filter types, pulsatile or continuous pump and thermal exchangers). On the basis of the patient's initialisation data (height, weight, Ht) and perfusion variables (pump flow rate, water temperature, gas flow rate and composition) imposed by the operator, the virtual ECC monitors simulated arterial and venous pressure tracings in real time, along with arterial and venous flow rate tracings, urine production tracing and temperature levels. Oxyhemoglobin arterial and venous blood saturation together with other related variables (pO2, pCO2, pH, HCO3) are also monitored. A drug model which allows the simulation of the effect of vasodilator and diuretic drugs is also implemented. Alarms are provided in order to check which variables (pressure, saturation, pH, urine flow) are out of the expected ranges during the ECC simulation. Consequently the possibility of modifying the control parameters of the virtual devices of the ECC in run-time mode offers an interaction mode between the operator and the virtual environment.
Performance of MIMO Aware RRM in Downlink OFDMA

This paper addresses advanced radio resource management (RRM) algorithms for multiple-input multiple-output (MIMO) transmission schemes in downlink OFDMA systems. The analysis covers the main RRM mechanisms including MIMO rank adaptation and time-frequency packet scheduling. The UTRAN Long Term Evolution (LTE) system is used as case study. System-level performance analysis is presented for 2 times 2 and 4 times 4 spatial-multiplexing, single-user MIMO transmission schemes in typical macro- and micro-cell scenarios including the effects of limited and imperfect CQI feedback from the terminals. We show that time-frequency domain RRM schemes can be successfully adapted and optimized for operations with high-rate adaptive MIMO transmission schemes.
Pyroxene-type compounds NaM3+Ge2O6, with M = Ga, Mn, Sc and In.

The four title compounds, namely sodium gallium germanate, NaGaGe2O6, sodium manganese vanadate germanate, NaMnV0.1Ge1. 9O6, sodium scandium germanate, NaScGe2O6, and sodium indium germanate, NaInGe2O6, adopt the high-temperature structure of the pyroxene-type chain germanates, with monoclinic symmetry and space group C2/c. The lattice parameters, the individual and average bond lengths involving M1, and the distortion parameters scale well with the ionic radius of the M1 cation. NaGaGe2O6 has more distorted M1 sites and more extended tetrahedral chains than NaInGe2O6, in which a high degree of kinking is required to maintain the connection between the octahedral and tetrahedral building units of the pyroxene structure. An exceptional case is NaMnGe2O6, in which the strong Jahn-Teller effect of Mn(3+) results in more distorted octahedral sites than expected according to linear extrapolation from the other NaM(3+)Ge2O6 pyroxenes. In contrast with the literature, minor incorporations of V(5+) in the tetrahedral site and a corresponding reduction of Mn(3+) to Mn(2+) in the octahedral sites in the present sample lower the Jahn-Teller distortion and stabilize the Mn-bearing pyroxene, even allowing its synthesis at ambient pressure.

The effect of octapressin on renal and intrarenal blood flow in cirrhosis of the liver 1

The effect of octapressin (2-phenylalanine-8-lysine vasopressin) on renal and intrarenal blood flow was studied in 11 normotensive cirrhotic patients with abnormal renal perfusion. Renal haemodynamic changes were assessed with the 133Xenon washout technique. Of the six patients given suppressor doses of octapressin intravenously renal blood flow improved in one only. A further three patients responded to the drug in a dose which increased the mean arterial pressure by 5 or more mm Hg. The increase in mean renal blood flow was accompanied by an improvement in renal cortical perfusion. In two patients renal blood flow decreased after the administration of octapressin. These findings, in conjunction with previous reports, suggest that octapressin will only consistently improve renal perfusion in cirrhotic subjects who are hypotensive and in whom the mean arterial blood pressure is raised by the drug, but do not exclude the possibility that octapressin may have a direct renal circulatory effect in some patients.
Neutrophil‐mediated oxidation of erythrocyte peroxiredoxin 2 as a potential marker of oxidative stress in inflammation

Peroxiredoxin 2 (Prx2) is an abundant thiol protein in erythrocytes. It is oxidized readily on exposure to hydrogen peroxide (H2O2) and provides antioxidant protection by cycling between its reduced and disulfide‐bonded forms. To test whether Prx2 oxidation could occur in pathological situations where neutrophils are activated, we exposed human erythrocytes to stimulated neutrophils and measured Prx2 oxidation by immunoblotting of nonreducing gels. With phorbol myristate acetate, lipopolysaccharide or Staphylococcus aureus Prx2 dimer increased from <5% to up to 100% depending on neutrophil number and incubation time. Studies with inhibitors and myeloperoxidase‐deficient neutrophils showed that H2O2 generated by the neutrophil NADPH oxidase was responsible. Prx2 oxidation was detected at erythrocyte:neutrophil ratios found in blood and reversed over time as the oxidative burst subsided. Acidotic conditions also increased erythrocyte Prx2 oxidation. In a mouse model of endotoxemia induced by lipopolysaccharide, oxidized Prx2 increased transiently from <1 to 15%, then reverted to baseline by 24 h. No increase was seen in mice lacking NADPH oxidase activity. These results indicate that erythrocyte Prx2 scavenges H2O2 produced during inflammation. Oxidized erythrocyte Prx2 could be a sensitive real‐time marker of systemic neutrophil activation and an early indicator of inflammation and oxidative stress. —Bayer, S.B. , Maghzal, G. , Stocker, R. , Hampton, M.B. , Winterbourn, C.C.

Health-State Utilities and Quality of Life in Hepatitis C Patients

OBJECTIVE:Health-state utilities are global measurements of quality of life on a scale from 0 (death) to 1 (full health). Utilities are used to evaluate health outcomes and are the preferred outcome measure for policy models that determine the cost-effectiveness of treatments. Currently, utilities for hepatitis C virus (HCV)-infected patients have been estimated using expert judgments. The purpose of this study was to elicit HCV utilities directly from patients.METHODS:We assessed the utilities of 193 outpatients at various stages of chronic HCV progression by using a visual analog scale, the standard gamble technique, the Health Utilities Index Mark 3 survey, and the EuroQol Index survey. We also incorporated the nonutility-based Short Form-36v2 survey, which provides a detailed profile of health status.RESULTS:The mean standard gamble utilities were: 0.78 for patients without a recent liver biopsy and no signs of cirrhosis; 0.79 for mild to moderate chronic HCV infection; 0.80 for compensated cirrhosis; 0.60 for decompensated cirrhosis; 0.72 for hepatocellular carcinoma; 0.73 for transplant; and 0.86 for sustained virological responders to interferon ± ribavirin treatment. The Health Utilities Index Mark 3 survey and the EuroQol Index survey utilities were lower than Canadian population norms (p < 0.001). Patient-elicited utilities were lower than previous expert estimates for mild/moderate chronic infection and sustained virological responders, but higher for decompensated cirrhosis and hepatocellular carcinoma. The Short Form-36v2 survey scores revealed several significant health impairments (p < 0.005) when compared with U.S. population norms.CONCLUSIONS:These findings 1) suggest that quality of life (QOL) differences across the HCV clinical spectrum are smaller than previously believed; 2) support other evidence suggesting that QOL is significantly diminished in HCV patients; and 3) provide utility values derived directly from HCV patients.
Modeling nonlinear optics of nanosystems with sum‐over‐states model

Three‐stage strategies (ladder rule, few state model (FSM), and parallelization) were proposed to improve the computational efficiency of the sum‐over‐states (SOS) model in nonlinear optics (NLO) modeling. Ladder rule decomposes NLO coefficients of the nth state into the (n−1)th term and the contribution from the (n−1)th to the nth state without loss of rigor in theory. FSM singles out the states with substantial contribution to NLO. Those strategies are universal to all (including revised and simplified) SOS models. The computing cost reduces roughly to C/(ni−1) (C is a constant and i is the rank (order) of the NLO coefficients). © 2011 Wiley Periodicals, Inc. J Comput Chem, 2012
The Evaluation of the Performance of Different Filtering Approaches in Tracking Problem and the Effect of Noise Variance

 Abstract — Performance of different filtering approaches depends on modeling of dynamical system and algorithm structure. For modeling and smoothing the data the evaluation of posterior distribution in different filtering approach should be chosen carefully. In this paper different filtering approaches like filter KALMAN, EKF, UKF, EKS and smoother RTS is simulated in some trajectory tracking of path and accuracy and limitation of these approaches are explained. Then probability of model with different filters is compered and finally the effect of the noise variance to estimation is described with simulations results.
Enlarged Ionization Region and Wiley-McLaren Type Geometry

The ionization region of the ToF mass spectrometer having the Wiley- McLaren geometry was further enlarged on the basis of the Milani–de Heer criteria. The enlarging limits the use of the spectrometer to small cluster range as a result of mass resolution decrease at great deal amount. However the spectrometer is promising for the electron-cluster interaction studies.
Les prémices du Petit Age Glaciaire en Roussillon à travers le prisme des sources écrites

Cet article a pour objectif de detecter les indices marquant le debut du Petit Age Glaciaire en Roussillon et de caracteriser le phenomene a partir des seules sources ecrites. Le recensement des evenements climatiques a partir de cette documentation est une demarche complexe, mais qui permet malgre tout de souligner que les accidents se multiplient a partir des annees 1310 et surtout 1330. En parallele, des campagnes d’endiguement des fleuves roussillonnais sont entreprises dans la plaine dans les annees 1330 -1340. Enfin, l’impact de cette pejoration climatique sur les modes d’occupation du sol est egalement tres difficile a definir. Notons toutefois, que, malgre des inondations recurrentes, causant l’ensablement de certains sites, les populations ont tente de resister. Les abandons de villages s’etalant sur l’extreme fin du Moyen Age, le fait climatique devient alors difficilement dissociable des autres crises.

Assessing the Misrepresentation of Health Problems

Although respondent misrepresentation in many areas of psychological testing has been widely studied, little is available for evaluating misrepresentation during health-related psychological assessments. In this article, I report the empirical development and validation of such scales for 2 screening inventories: the Psychological Screening Inventory (the HPO scale; Lanyon, 1970, 1978) and the Multidimensional Health Profile (the HPE scale; Ruehlman, Lanyon, & Karoly, 1998a, 1998b, 1999). In each case, judges were asked to simulate the misrepresentation of health problems. Items were selected whose frequencies differed from normal responding; these items were screened for marked content irrelevance and further refined using data from additional respondents. Validation data showed that for both scales the group means for persons with genuine health problems were up to 1 SD above the normative mean, and the means for suspected and actual simulators were about 2 SDs higher than the health-problem groups.
Geochemistry of Cenozoic Basaltic Rocksaround Liuhe National Geopark, Jiangsu Province, Eastern China: Petrogenesis and Mantle Source

— Cenozoic basalts found in Jiangsu province of eastern China include tholeiites and alkali basalts. The present paper analyzed the major, trace elements, rare earth elements of these Cenozoic basalts and combined with Sr-Nd isotopic compositions proposed by Chen et al. (1990)[1] in the literatures to discuss the petrogenesis of these basalts and the geochemical characteristics of the source mantle. Based on major, trace elements and fractional crystallization model established by Brooks and Nielsen (1982)[2] we suggest that the basaltic magma has experienced olivine + clinopyroxene fractionation during its evolution. The chemical compositions of basaltic rocks from Jiangsu province indicate that these basalts may belong to the same magmatic system. Spidergrams reveal that Cenozoic basalts from Jiangsu province have geochemical characteristics similar to those of ocean island basalts(OIB). The slight positive Nb and Ti anomalies found in basaltic rocks of this study suggest the presence of Ti-bearing minerals in the mantle source and these Ti-bearing minerals had contributed to basaltic magma during partial melting, indicating a metasomatic event might have occurred before the partial melting. Based on the Sr vs. Nd isotopic ratio plots, we suggest that Jiangsu basalts may be derived from partial melting of mantle source which may represent two-end members mixing of DMM and EM-I. Some Jiangsu basaltic magma may be derived from partial melting of EM-I heated by the upwelling asthenospheric mantle or asthenospheric diapirism.
