Identifying Optimal Initial Infusion Rates for Unfractionated Heparin in Morbidly Obese Patients
Authors: Riney Jennifer N , Hollands James M , Smith Jennifer R , Deal Eli N 
Published: June 2010

Background: Most literature available for unfractionated heparin (UFH) supports the use of actual body weight for dosing all patients, yet a small proportion of the patients in these studies were morbidly obese. The most appropriate dosing strategy for therapeutic UFH in this patient population is not clearly defined. Objective: To better define appropriate UFH dosing strategies in morbidly obese patients and to evaluate the safety of a weight-based heparin nomogram in this patient population. Methods: Patients with class III (morbid) obesity receiving therapeutic doses of a UFH infusion for greater than 24 hours were evaluated. Two comparator groups of overweight/class I–II obesity and normal/underweight patients were created by matching patients to the class III obesity group. Doses and times to therapeutic activated partial thromboplastin time (aPTT), bleeding rates, and mortality were assessed. Results: The mean infusion rate required to obtain a first therapeutic aPTT was 11.5 units/kg/h in the class III obesity group (n = 94) versus 12.5 units/kgm and 13.5 units/kg/h for the overweight/class I–II obesity (n = 92) and normal/underweight (n = 87) groups, respectively (p = 0.001). The mean times to a first therapeutic aPTT were 21.3, 22.1, and 29.9 hours, respectively (p = 0.421). There was a statistically significant difference in the infusion rate required to obtain 2 consecutive therapeutic aPTTs between groups (p = 0.016), with higher weight groups requiring smaller (per kilogram actual body weight) infusion rates, but there was no significant difference in the time to reach 2 consecutive therapeutic aPTTs (p = 0.776). There was no significant difference in bleeding (p = 0.517) or mortality (p = 0.475) among groups. Conclusions: Morbidly obese patients require smaller UFH infusion rates per kilogram actual body weight compared to patients with lower body mass indices. UFH dosing recommendations should be modified to reflect body mass index classification.
In‐group and role identity influences on the initiation and maintenance of students' voluntary attendance at peer study sessions for statistics
Authors: White Katherine M. , O'Connor Erin L. , Hamilton Kyra 
Published: June 2010

Background. Although class attendance is linked to academic performance, questions remain about what determines students' decisions to attend or miss class. Aims. In addition to the constructs of a common decision‐making model, the theory of planned behaviour, the present study examined the influence of student role identity and university student (in‐group) identification for predicting both the initiation and maintenance of students' attendance at voluntary peer‐assisted study sessions in a statistics subject. Sample. University students enrolled in a statistics subject were invited to complete a questionnaire at two time points across the academic semester. A total of 79 university students completed questionnaires at the first data collection point, with 46 students completing the questionnaire at the second data collection point. Method. Twice during the semester, students' attitudes, subjective norm, perceived behavioural control, student role identity, in‐group identification, and intention to attend study sessions were assessed via on‐line questionnaires. Objective measures of class attendance records for each half‐semester (or ‘term’) were obtained. Results. Across both terms, students' attitudes predicted their attendance intentions, with intentions predicting class attendance. Earlier in the semester, in addition to perceived behavioural control, both student role identity and in‐group identification predicted students' attendance intentions, with only role identity influencing intentions later in the semester. Conclusions. These findings highlight the possible chronology that different identity influences have in determining students' initial and maintained attendance at voluntary sessions designed to facilitate their learning.
Accuracy of MUAC in the Detection of Severe Wasting With the New WHO Growth Standards
Authors: Fernández Miguel Ángel Luque , Delchevalerie Pascale , van Herp Michel 
Published: June 2010

OBJECTIVES:
The objectives of this study were to estimate the accuracy of using mid-upper-arm circumference (MUAC) measurements to diagnose severe wasting by comparing the new standards from the World Health Organization (WHO) with those from the US National Center for Health Statistics (NCHS) and to analyze the age independence of the MUAC cutoff values for both curves.

METHODS:
We used cross-sectional anthropometric data for 34 937 children between the ages of 6 and 59 months, from 39 nutritional surveys conducted by Doctors Without Borders. Receiver operating characteristic curves were used to examine the accuracy of MUAC diagnoses. MUAC age independence was analyzed with logistic regression models.

RESULTS:
With the new WHO curve, the performance of MUAC measurements, in terms of sensitivity and specificity, deteriorated. With different cutoff values, however, the WHO standards significantly improved the predictive value of MUAC measurements over the NCHS standards. The sensitivity and specificity of MUAC measurements were the most age independent when the WHO curve, rather than the NCHS curve, was used.

CONCLUSIONS:
This study confirms the need to change the MUAC cutoff value from &lt;110 mm to &lt;115 mm. This increase of 5 mm produces a large change in sensitivity (from 16% to 25%) with little loss in specificity, improves the probability of diagnosing severe wasting, and reduces false-negative results by 12%. This change is needed to maintain the same diagnostic accuracy as the old curve and to identify the children at greatest risk of death resulting from severe wasting.
Maternal Smoking and Child Psychological Problems: Disentangling Causal and Noncausal Effects
Authors: Brion Marie-Jo , Victora Cesar , Matijasevich Alicia , Horta Bernardo , Anselmi Luciana , Steer Colin , Menezes Ana Maria B. , Lawlor Debbie A. , Davey Smith George 
Published: June 2010

OBJECTIVE:
To explore associations of maternal prenatal smoking and child psychological problems and determine the role of causal intrauterine mechanisms.

PATIENTS AND METHODS:
Maternal smoking and child psychological problems were explored in 2 birth cohorts in Pelotas, Brazil (n = 509, random subsample), and the Avon Longitudinal Study of Parents and Children (ALSPAC) in Britain (n = 6735). Four approaches for exploring causal mechanisms were applied: (1) cross-population comparisons between a high-income and a middle-income country; (2) multiple adjustment for socioeconomic and parental psychological factors; (3) maternal-paternal comparisons as a test of putative intrauterine effects; and (4) searching for specific effects on different behavioral subscales.

RESULTS:
Socioeconomic patterning of maternal prenatal smoking was stronger in the ALSPAC compared with the Pelotas cohort. Despite this difference in a key confounder, consistency in observed associations was found between these cohorts. In both cohorts, unadjusted maternal smoking was associated with greater offspring hyperactivity, conduct/externalizing problems, and peer problems but not with emotional/internalizing problems. After adjusting for confounders and paternal prenatal smoking, only the association with conduct/externalizing problems persisted in both cohorts (conduct problems in the ALSPAC cohort, odds ratio [OR]: 1.24 [95% confidence interval (CI): 1.07–1.46], P = .005; externalizing problems in the Pelotas cohort, OR: 1.82 [95% CI: 1.19–2.78], P = .005; ORs reflect ordinal odds ratios of maternal smokers having offspring with higher scores). Maternal smoking associations were stronger than paternal smoking associations, although statistical evidence that these associations differed was weak in 1 cohort.

CONCLUSION:
Evidence from 4 approaches suggests a possible intrauterine effect of maternal smoking on offspring conduct/externalizing problems.

A comparison between the algebraic and the reduced order observer approaches for on‐line load torque estimation in a unit power factor rectifier‐DC motor system
Authors: Linares‐Flores J. , Sira‐Ramírez H. , Yescas‐Mendoza E. , Vásquez‐Sanjuan J. J. 
Published: June 2010

AbstractIn this article, a comparison between the performances of an online algebraic estimator and a reduced order observer is established in the context of adaptive load torque estimation in a controlled unit power factor rectifier‐DC motor system combination. A passivity‐based output feedback controller was constructed to regulate the angular speed while correcting the power factor of the mono phase boost rectifier. The proposed controller allowed us to compare the results of both on‐line estimation techniques. The experimental results show a superiority of the algebraic approach in which the angular velocity was maintained at the desired reference value by the adapted controller, even under severe load changes on the motor shaft, while the power factor was also kept at high values in the power supply system.Copyright © 2010 John Wiley and Sons Asia Pte Ltd and Chinese Automatic Control Society

Authors: Millon Oliver , Mechtcherine Viktor , Thoma Klaus , Butler Marko 
Published: June 2010

AbstractIn diesem Aufsatz wird das Materialverhalten von Hochduktilem Beton (engl.: Strain Hardening Cementitious Composite – SHCC) bei Impaktbelastung beschrieben. Dazu werden Ergebnisse aus hochdynamischen Spallations‐Experimenten an einem Hopkinson‐ Bar mit Dehnraten > 140 1/s den Resultaten aus quasi‐statischen, zentrischen Zugversuchen mit Dehnraten von 0,001 1/s gegenübergestellt. Die Auswirkungen hoher Dehnraten auf das Materialverhalten erfolgt anhand eines Vergleiches der zentrischen Zugfestigkeit, des E‐Moduls sowie der Bruchenergie. Die experimentellen Ergebnisse werden zudem mit den Kennwerten anderer Betone in Beziehung gesetzt. Unterschiede im Materialverhalten werden auf Grundlage von Phänomenen der Rissbildung und des Faserauszuges erklärt.Mechanical Behaviour of SHCC under ImpactThis paper describes the material behaviour of Strain Hardening Cementitious Composite (SHCC) at high strain rates. The results of high dynamic spall experiments using a Hopkinson Bar at strain rates > 140/sec were arrayed against the results of quasistatic, centric tensile tests at strain rates of 0,001/sec. This comparison is based on the parameters of tensile strength, elastic modulus, and fracture energy of the specimens. In addition, the experimental results of SHCC are related to the characteristic values of other concrete types. Differences in material behaviour are explained by the phenomena of crack formation and fibre pullout force.
