Hypoalbuminemia is a predictor of delayed postoperative bowel function and poor surgical outcomes in right-sided colon cancer patients.

PURPOSE To determine the relationship between preoperative serum albumin and postoperative bowel function as well as surgical outcomes in right-sided colon cancer patients. METHODS This retrospective study in a university hospital included 84 patients who underwent elective right hemicolectomy for adenocarcinoma of the right-sided colon between January 2004 and December 2005. The patients had a preoperative serum albumin assessment. Serum albumin less than 3.5 g/dL was regarded as hypoalbuminemia. Postoperative outcomes were classified into mortality, morbidity (infectious and noninfectious complications), time to first bowel movement, time to resume normal diet, and hospital stay. RESULTS Forty males (48%) and forty-four females (52%) with a mean age of 64 (range, 27-89) years were included. Forty-eight patients (57%) had hypoalbuminemia. No 30-day postoperative mortality occurred. All 14 postoperative complications occurred in hypoalbuminemic cases. Therefore, 29% of the hypoalbuminemics had complications whereas none occurred in nonhypoalbuminemics (p=0.001). In univariate analysis, hypoalbuminemia and postoperative complications were the risk factors for delayed postoperative recovery of bowel function and prolonged length of hospital stay. In multivariate analysis, hypoalbuminemia was the significant risk factor for postoperative complications (p<0.001) and delayed time to first bowel movement (p=0.018) whereas postoperative complications were the significant risk factor for delayed time to resume normal diet (p<0.001) and prolonged hospital stay (p<0.001). CONCLUSION Hypoalbuminemia is a potential predictor of delayed recovery of bowel function postoperatively and significantly associated with postoperative complications in right-sided colon cancer patients undergone right hemicolectomy.
A Specific Association between Facial Disgust Recognition and Estradiol Levels in Naturally Cycling Women

Subtle changes in social cognition are associated with naturalistic fluctuations in estrogens and progesterone over the course of the menstrual cycle. Using a dynamic emotion recognition task we aimed to provide a comprehensive description of the association between ovarian hormone levels and emotion recognition performance using a variety of performance metrics. Naturally cycling, psychiatrically healthy women attended a single experimental session during a follicular (days 7–13; n = 16), early luteal (days 15–19; n = 14) or late luteal phase (days 22–27; n = 14) of their menstrual cycle. Correct responses and reaction times to dynamic facial expressions were recorded and a two-high threshold analysis was used to assess discrimination and response bias. Salivary progesterone and estradiol were assayed and subjective measures of premenstrual symptoms, anxiety and positive and negative affect assessed. There was no interaction between cycle phase (follicular, early luteal, late luteal) and facial expression (sad, happy, fearful, angry, neutral and disgusted) on any of the recognition performance metrics. However, across the sample as a whole, progesterone levels were positively correlated with reaction times to a variety of facial expressions (anger, happiness, sadness and neutral expressions). In contrast, estradiol levels were specifically correlated with disgust processing on three performance indices (correct responses, response bias and discrimination). Premenstrual symptoms, anxiety and positive and negative affect were not associated with emotion recognition indices or hormone levels. The study highlights the role of naturalistic variations in ovarian hormone levels in modulating emotion recognition. In particular, progesterone seems to have a general slowing effect on facial expression processing. Our findings also provide the first behavioural evidence of a specific role for estrogens in the processing of disgust in humans.
Identification errors involving clinical laboratories: a College of American Pathologists Q-Probes study of patient and specimen identification errors at 120 institutions.

CONTEXT Misidentified laboratory specimens may cause patient injury, but their frequency in general laboratory practice is unknown. OBJECTIVES To determine (1) the frequency of identification errors detected before and after result verification, (2) the frequency of adverse patient events due to specimen misidentification, and (3) factors associated with lower error rates and better detection of errors. DESIGN One hundred twenty clinical laboratories provided information about identification errors during 5 weeks. RESULTS In aggregate, 85% of errors were detected before results were released; one quarter of laboratories identified more than 95% of errors before result verification. The overall rate of patient identification errors involving released results was 55 errors per 1,000,000 billable tests. A total of 345 adverse events were reported. Most of the adverse events caused material inconvenience to the patients but did not result in any permanent harm. On average, adverse events resulted from 1 of every 18 identification errors. Extrapolating the adverse event rate observed in this study to all United States hospital-based laboratories suggests that more than 160,000 adverse events per year result from misidentification of patients' laboratory specimens. CONCLUSIONS Identification errors are common in laboratory medicine, but most are detected before results are released, and only a fraction are associated with adverse patient events. Even when taking into consideration the design of this study, which used imperfect case finding, institutions that did a better job of detecting errors within the laboratory released a smaller proportion of results that involved specimen misidentification.
Gravitoelectromagnetism: a Brief Review 1.1 Introduction

The main theoretical aspects of gravitoelectromagnetism (" GEM ") are presented. Two basic approaches to this subject are described and the role of the gravitational Larmor theorem is emphasized. Some of the consequences of GEM are briefly mentioned. The analogy between gravitation and electromagnetism has a long history. The similarity between Newton's law of gravitation and Coulomb's law of electricity naturally led to a gravitoelectric description of Newtonian gravitation. Moreover, on the basis of advances in electrodynamics in the second half of the nineteenth century, Holzmüller [1] and Tisserand [2] postulated that the gravitational force exerted by the Sun on the planets of the solar system had an additional " magnetic " component. This extra force led to the precession of the planetary orbits; therefore, it could be adjusted in order to account for the excess perihelion precession of Mercury. Decades later, however, Einstein's general relativity provided a beautiful explanation of the excess motion of Mercury's perihelion in terms of a relativistic gravitoelectric correction to the Newtonian gravitational potential of the Sun [3]. Furthermore, general relativity, which is a field theory of gravitation, contains a gravitomagnetic field due to mass current [4]. Indeed, to bring together Newtonian gravitation and Lorentz invariance in a consistent field-theoretic framework, the introduction of a gravitomagnetic field is unavoidable.
Metabolic Syndrome, Brain Magnetic Resonance Imaging, and Cognition

OBJECTIVE We explored cognitive impairment in metabolic syndrome in relation to brain magnetic resonance imaging (MRI) findings. RESEARCH DESIGN AND METHODS We studied 819 participants free of clinical stroke and dementia of the population-based Austrian Stroke Prevention Study who had undergone brain MRI, neuropsychological testing, and a risk factor assessment relevant to National Cholesterol Education Program Adult Treatment Panel III criteria–defined metabolic syndrome. High-sensitivity C-reactive protein (hs-CRP) was also determined. RESULTS Of 819 subjects, 232 (28.3%) had metabolic syndrome. They performed worse than those without metabolic syndrome on cognitive tests assessing memory and executive functioning after adjustment for possible confounders. Stratification by sex demonstrated that metabolic syndrome was related to cognitive dysfunction in men but not in women. Only in men was an increasing number of metabolic syndrome components associated with worse cognitive performance. MRI showed no significant differences in focal ischemic lesions and brain volume between subjects with and without metabolic syndrome, and MRI abnormalities failed to explain impaired cognition. Cognitive performance was most affected in male subjects with metabolic syndrome who also had high hs-CRP levels. CONCLUSIONS Metabolic syndrome exerts detrimental effects on memory and executive functioning in community-dwelling subjects who have not had a clinical stroke or do not have dementia. Men are more affected than women, particularly if they have high inflammatory markers. MRI-detected brain abnormalities do not play a crucial role in these relationships.

Look-alike audience extension is a practically effective way to customize high-performance audience in on-line advertising. With look-alike audience extension system, any advertiser can easily generate a set of customized audience by just providing a list of existing customers without knowing the detailed targetable attributes in a sophisticated advertising system. In this paper, we present our newly developed graph-based look-alike system in Yahoo! advertising platform which provides look-alike audiences for thousands of campaigns. Extensive experiments have been conducted to compare our look-alike model with three other existing look-alike systems using billions of users and millions of user features. The experiment results show that our developed graph-based method with nearest-neighbor filtering outperforms other methods by more than 50% regarding conversion rate in app-install ad campaigns.
Keck Spectroscopy of Distant GOODS Spheroidal Galaxies: Downsizing in a Hierarchical Universe

We analyze the evolution of the fundamental plane for 141 field spheroidal galaxies in the redshift range 0.2 < z < 1.2, selected morphologically to a magnitude limit F850LP = 22.43 in the northern field of the Great Observatories Origins Deep Survey. For massive galaxies, we find that the bulk of the star formation was completed prior to z = 2. However, for the lower mass galaxies, the luminosity-weighted ages are significantly younger. The differential change in mass-to-light ratio correlates closely with rest-frame color, consistent with recent star formation and associated growth. Our data are consistent with mass rather than environment governing the overall growth, contrary to the expectations of hierarchical assembly. We discuss how feedback, conduction, and galaxy interactions may explain the downsizing trends seen within our large sample.

ACCOUNTING QUALITY , BOND LIQUIDITY , AND THE COST OF DEBT

This paper investigates the role of accounting quality in improving bond liquidity and its implication on the cost of debt. We argue that high accounting quality not only reduces information asymmetry, but also decreases overall uncertainty in the market, thereby improving liquidity. We first document that higher accounting quality is associated with higher bond liquidity. We then show that the previously documented effect of accounting quality in reducing the cost of debt is largely through the improved liquidity. This is the first paper that examines the role of accounting quality in the bond market, and our results highlight the importance of information quality in improving liquidity.
Racial and ethnic variation in access to healthcare, provision of healthcare services, and ratings of health among women with a history of gestational diabetes mellitus

Objective To assess racial/ethnic variation in access to healthcare, use of particular healthcare services, presence of cardiovascular risk factors, and perceptions of health and impairment among women at risk for type 2 diabetes because of their history of gestational diabetes mellitus (hGDM) Research Design and Methods We performed a cross-sectional study using the 2001-2003 Behavioral Risk Factor Surveillance System, a national population-based random sample telephone survey. We assessed access to healthcare, use of family planning, measurement and elevation of cholesterol, elevation of blood pressure, and respondents’ perceptions of health and impairment among women aged 18-44 years with hGDM (n=4,718). Multivariate models adjusted for sociodemographic characteristics, body mass index, presence of children in the household, and current smoking. Results Outcome measures were suboptimal across racial/ethnic groups. Approximately 1/5 of the overall population reported no health insurance, cost barriers to visits, and no primary provider. One-quarter had no exam within the past year, and almost 1/5 reported no family planning and elevated cholesterol levels. Latinas were the most disadvantaged, with 40% reporting no health insurance and no primary care provider and 1/4 reporting suboptimal perceptions of health. Asian/Pacific Islanders were the most advantaged in terms of healthcare access, cholesterol and blood pressure elevation, and impaired physical health. Racial/ethnic differences in healthcare use and presence of risk factors were not entirely explained by healthcare access or other covariates. Conclusions Significant racial/ethnic variation exists among women with hGDM regarding access to and use of healthcare, presence of risk factors, and perceptions of health.
Surface Finish and Residual Stresses Induced by Orthogonal Dry Machining of AA7075-T651

The surface finish was extensively studied in usual machining processes (turning, milling, and drilling). For these processes, the surface finish is strongly influenced by the cutting feed and the tool nose radius. However, a basic understanding of tool/surface finish interaction and residual stress generation has been lacking. This paper aims to investigate the surface finish and residual stresses under the orthogonal cutting since it can provide this information by avoiding the effect of the tool nose radius. The orthogonal machining of AA7075-T651 alloy through a series of cutting experiments was performed under dry conditions. Surface finish was studied using height and amplitude distribution roughness parameters. SEM and EDS were used to analyze surface damage and built-up edge (BUE) formation. An analysis of the surface topography showed that the surface roughness was sensitive to changes in cutting parameters. It was found that the formation of BUE and the interaction between the tool edge and the iron-rich intermetallic particles play a determinant role in controlling the surface finish during dry orthogonal machining of the AA7075-T651 alloy. Hoop stress was predominantly compressive on the surface and tended to be tensile with increased cutting speed. The reverse occurred for the surface axial stress. The smaller the cutting feed, the greater is the effect of cutting speed on both axial and hoop stresses. By controlling the cutting speed and feed, it is possible to generate a benchmark residual stress state and good surface finish using dry machining.
MIMO channel measurements for personal area networks

This paper analyzes MIMO propagation channels for personal area networks. Such channels show important differences to propagation channels in wide-area networks, due to the different environments in which the systems are operated, as well as due to different mobility models, ranges, and presence of humans in the environment, and the impact of the antenna arrangement. We present results from a recent measurement campaign for this type of channel. We first analyze the requirements for measurement setups, especially in terms of different positions and orientations of the antenna arrays, to obtain meaningful results. We then analyze the measured data and present results for path loss, power delay profiles, spatial correlation and temporal correlation.
Granulocyte/Macrophage Colony-Stimulating Factor Influences Angiogenesis by Regulating the Coordinated Expression of VEGF and the Ang/Tie System

Granulocyte/macrophage colony-stimulating factor (GM-CSF) can accelerate wound healing by promoting angiogenesis. The biological effects of GM-CSF in angiogenesis and the corresponding underlying molecular mechanisms, including in the early stages of primitive endothelial tubule formation and the later stages of new vessel maturation, have only been partially clarified. This study aimed to investigate the effects of GM-CSF on angiogenesis and its regulatory mechanisms. Employing a self-controlled model (Sprague-Dawley rats with deep partial-thickness burn wounds), we determined that GM-CSF can increase VEGF expression and decrease the expression ratio of Ang-1/Ang-2 and the phosphorylation of Tie-2 in the early stages of the wound healing process, which promotes the degradation of the basement membrane and the proliferation of endothelial cells. At later stages of wound healing, GM-CSF can increase the expression ratio of Ang-1/Ang-2 and the phosphorylation of Tie-2 and maintain a high VEGF expression level. Consequently, pericyte coverages were higher, and the basement membrane became more integrated in new blood vessels, which enhanced the barrier function of blood vessels. In summary, we report here that increased angiogenesis is associated with GM-CSF treatment, and we indicate that VEGF and the Ang/Tie system may act as angiogenic mediators of the healing effect of GM-CSF on burn wounds.
Analysis of Flow Cytometry Data by Matrix Relevance Learning Vector Quantization

Flow cytometry is a widely used technique for the analysis of cell populations in the study and diagnosis of human diseases. It yields large amounts of high-dimensional data, the analysis of which would clearly benefit from efficient computational approaches aiming at automated diagnosis and decision support. This article presents our analysis of flow cytometry data in the framework of the DREAM6/FlowCAP2 Molecular Classification of Acute Myeloid Leukemia (AML) Challenge, 2011. In the challenge, example data was provided for a set of 179 subjects, comprising healthy donors and 23 cases of AML. The participants were asked to provide predictions with respect to the condition of 180 patients in a test set. We extracted feature vectors from the data in terms of single marker statistics, including characteristic moments, median and interquartile range of the observed values. Subsequently, we applied Generalized Matrix Relevance Learning Vector Quantization (GMLVQ), a machine learning technique which extends standard LVQ by an adaptive distance measure. Our method achieved the best possible performance with respect to the diagnoses of test set patients. The extraction of features from the flow cytometry data is outlined in detail, the machine learning approach is discussed and classification results are presented. In addition, we illustrate how GMLVQ can provide deeper insight into the problem by allowing to infer the relevance of specific markers and features for the diagnosis.
The Use of the L-Curve in the Regularization of Discrete Ill-Posed Problems

Regularization algorithms are often used to produce reasonable solutions to ill-posed problems. The L-curve is a plot—for all valid regularization parameters—of the size of the regularized solution versus the size of the corresponding residual. Two main results are established. First a unifying characterization of various regularization methods is given and it is shown that the measurement of “size” is dependent on the particular regularization method chosen. For example, the 2-norm is appropriate for Tikhonov regularization, but a 1-norm in the coordinate system of the singular value decomposition (SVD) is relevant to truncated SVD regularization. Second, a new method is proposed for choosing the regularization parameter based on the L-curve, and it is shown how this method can be implemented efficiently. The method is compared to generalized cross validation and this new method is shown to be more robust in the presence of correlated errors.
Prediction of Short-Term Outcome in Acute Superior Vestibular Nerve Failure: Three-Dimensional Video-Head-Impulse Test and Caloric Irrigation

This retrospective study examines acute unilateral vestibular failure (up to seven days after onset) with modern vestibular testing (caloric irrigation and video-head-impulse test, vHIT) in 54 patients in order to test if the short-term outcome of the patients depends on the lesion pattern defined by the two tests. Patients were grouped according to a pathological unilateral caloric weakness without a pathological vHIT: group I; additional a pathological vHIT of the lateral semicircular canal (SCC): group II; and an additional pathological vHIT of the anterior SCC: group III. Patients with involvement of the posterior SCC were less frequent and not included in the analysis. Basic parameters, such as age of the subjects, days after symptom onset, gender, side of the lesion, treatment, and dizziness handicap inventory, were not different in groups I to III. The frequency of pathological clinical findings and pathological quantified measurements increased from groups I to III. The outcome parameter “days spent in the hospital” was significantly higher in group III compared to group I. The analysis shows that differential vestibular testing predicts short-term outcome of the patients and might be in future important to treat and coach patients with vestibular failure.
