Diagnosing gestational diabetes mellitus in women following bariatric surgery: A national survey of lead diabetes midwives
Authors: Whyte Martin , Johnson Roisin , Cooke Deborah , Hart Kathryn , McCormack Marie , Shawe Jill 
Published: June 2016

Background: Bariatric surgery is becoming more common among women of fertile age to manage obesity. The number of pregnancies following bariatric surgery is, therefore, likely to rise. The standard oral glucose tolerance test (OGTT) may lead to dizziness, sweating and collapse in people after some types of bariatric surgery. Aims: In view of this potential pitfall in the diagnosis of gestational diabetes mellitus (GDM) after bariatric surgery, the authors surveyed midwifery units to establish current practice for the screening and diagnosis of GDM in women who have had bariatric surgery. Methods: Out of 164 English obstetric units, 120 email surveys were sent to a network of lead diabetes midwives in units across England. A reminder email was sent 4 weeks later. Findings: Twenty-seven (22.5%) responses were received. Five respondents (26%) had specific policies in place to manage pregnancies after bariatric surgery. A wide variety of approaches to GDM screening and diagnosis were used in women with a history of bariatric surgery. The OGTT was the most widely used test after bariatric surgery. Conclusions: There is a need for national clinical guidelines to be developed for the diagnosis of GDM after bariatric surgery.

Published: June 2016

Introduction/Objective: Pulmonary function tests (PFTs) are objective estimates of
lung function, but are not reliably stored within the Veteran Health Affairs data
systems as structured data. The aim of this study was to validate the natural language
processing (NLP) tool we developed—which extracts spirometric values and responses to
bronchodilator administration—against expert review, and to estimate the number of
additional spirometric tests identified beyond the structured data.Methods: All patients
at seven Veteran Affairs Medical Centers with a diagnostic code for asthma Jan 1,
2006–Dec 31, 2012 were included. Evidence of spirometry with a bronchodilator challenge
(BDC) was extracted from structured data as well as clinical documents. NLP’s
performance was compared against a human reference standard using a random sample of
1,001 documents.Results: In the validation set NLP demonstrated a precision of 98.9
percent [d1] (95 percent confidence intervals (CI): 93.9 percent, 99.7 percent), recall
of 97.8 percent (95 percent CI: 92.2 percent, 99.7 percent), and an F-measure of 98.3
percent for the forced vital capacity pre- and post pairs and precision of 100 percent
(95 percent CI: 96.6 percent, 100 percent), recall of 100 percent (95 percent CI: 96.6
percent, 100 percent), and an F-measure of 100 percent for the forced expiratory volume
in one second pre- and post pairs for bronchodilator administration. Application of the
NLP increased the proportion identified with complete bronchodilator challenge by 25
percent.Discussion/Conclusion: This technology can improve identification of PFTs for
epidemiologic research. Caution must be taken in assuming that a single domain of
clinical data can completely capture the scope of a disease, treatment, or clinical
test.Key words: asthma, bronchodilator challenge, natural language processing, pulmonary

Predicting Empirical Patterns in Viewing Japanese TV Dramas Using Case-Based Decision Theory
Authors: Kinjo Keita , Sugawara Shinya 
Published: June 2016

AbstractThis article empirically analyzes consumer behavior of viewing TV dramas using case-based decision theory. The theory addresses an economic situation with structural ignorance, where states of the world are not naturally given nor simply formulated for a decision-maker. Under this theory, consumers make decisions based on subjective evaluations of previous purchases for similar goods. Our empirical analysis is concerned with viewing decisions on getsuku, the Japanese TV dramas broadcast at 9 pm Monday by the Fuji Television Network. The regularity of the schedule and the long-sustaining popularity of the program enable us to easily collect consumer data. Then, we conduct a web survey of individual audiences on subjective evaluations of previously watched dramas. For our empirical analysis, we utilize a simple linear model of the case-based model that allows the incorporation of flexible inference techniques. Our results demonstrate better performance of the case-based models than models based on traditional expected utility theory regarding both statistical model selection and one-step-ahead prediction. We also reveal that the successful performance of the case-based model in our analysis depends on the availability of individual subjective evaluations and that it is difficult to replace the individual-specific information using demographic information and aggregate data.
Sellers’ Implicit Collusion in Directed Search Markets
Authors: Han Seungjin 
Published: June 2016

AbstractThis paper studies a competing-mechanism game for directed search markets in which multiple sellers simultaneously offer selling mechanisms to multiple buyers in order to compete for trading opportunities and profits. Buyers approach any particular seller via directed search, but there can be mis-coordination among buyers in the sense that they choose all the sellers offering the same mechanism with equal probability. A seller’s mechanism can be sufficiently general to make his trading price contingent on participating buyers’ messages, which may reflect changes in trading prices somewhere else. This allows sellers to sustain implicit collusion. This paper focuses on symmetric equilibria in which sellers offer the same mechanism that induces buyers’ ex-post truth telling on market information. It provides the characterization of all symmetric ex-post truth telling equilibrium allocations and comparative statics regarding the range of equilibrium prices and profits. In a large market, the probability that sellers can sell their products at collusive prices depends on the ratio of buyers to sellers.
Separation of Intercepted Multi-Radar Signals Based on Parameterized Time-Frequency Analysis
Authors: Lu W. L. , Xie J. W. , Wang H. M. , Sheng C. 
Published: June 2016

AbstractModern radars use complex waveforms to obtain high detection performance and low probabilities of interception and identification. Signals intercepted from multiple radars overlap considerably in both the time and frequency domains and are difficult to separate with primary time parameters. Time–frequency analysis (TFA), as a key signal-processing tool, can provide better insight into the signal than conventional methods. In particular, among the various types of TFA, parameterized time-frequency analysis (PTFA) has shown great potential to investigate the time–frequency features of such non-stationary signals. In this paper, we propose a procedure for PTFA to separate overlapped radar signals; it includes five steps: initiation, parameterized time-frequency analysis, demodulating the signal of interest, adaptive filtering and recovering the signal. The effectiveness of the method was verified with simulated data and an intercepted radar signal received in a microwave laboratory. The results show that the proposed method has good performance and has potential in electronic reconnaissance applications, such as electronic intelligence, electronic warfare support measures, and radar warning.
Liquorzytologie: Eine aussagekräftige Methode zur Diagnostik von Erkrankungen des Zentralnervensystems
Authors: Torzewski Michael , Lackner Karl J. 
Published: June 2016

Zusammenfassung:
Die Liquorzytologie ist eine technisch vergleichsweise einfache, dabei aber diagnostisch aussagefähige, schnell durchzuführende und kostengünstige Untersuchung, die auch im Rahmen des Notfall- und Basisprogramms der Liquordiagnostik nicht fehlen sollte. Die korrekte Durchführung und Interpretation setzt allerdings einige Erfahrung voraus. Anhand ausgewählter Beispiele zu den Themen Blutung, Meningitis und Meningeosis wird die Wertigkeit der Zytologie demonstriert, die oftmals nicht nur eine Ergänzung zu den üblichen quantitativen Bestimmungen ist, sondern nicht selten auch erst den diagnostisch entscheidenden Hinweis auf die zugrundliegende Erkrankung liefert: Bei der Subarachnoidalblutung ist sie hinsichtlich der Sensitivität der kranialen Computertomographie oftmals überlegen. Bei einer parasitären Meningitis liefert sie aufgrund des Nachweises eosinophiler Granulozyten erst die wesentliche Differentialdiagnose. Auch hinter einer normalen Zellzahl verbirgt sich gelegentlich eine Meningeois neoplastica. Tumorzellen lassen sich dabei mit Hilfe der Immunzytologie näher zuordnen. Entscheidend für eine aussagekräftige Zytologie ist allerdings die strikte Einhaltung präanalytischer Anforderungen.
Characterization and modeling of nanotips fabricated in the field ion microscope
Authors: Ali Ahmed , Barada Hassan , Rezeq Moh’d 
Published: June 2016

AbstractNanotips are considered significant elements in some of nanotechnology instruments. They are used in scanning probe microscopes and electron microscopes to characterize materials at the nano and atomic scales. Therefore, the size and profile of the nanotip determines the performance of these microscopes. The advancement of nanotip fabrication techniques has enabled the fabrication of ultra-sharp tips and even single-atom tips. However, the characterization of nanotips with an apex of a few nanometers is still premature, while the conventional characterization methods of the tip size, such as the ring counting method, have shown some limitation at this nano scale. In this paper, we review the various nanotip fabrication methods with a focus on the most recent one, which is called the local electron bombardment method. We demonstrate an approach for estimating the nanotip radius with good approximation using ball crystal models. We also model the overall nanotip profile using finite element simulation tools based on the hyperboloidal geometry. The modeling and radius estimation approach is applied on tips fabricated by the local electron bombardment method, which will be explained in detail as well.
The Subterranean Influence of Pragmatism on the Vienna Circle: Peirce, Ramsey, Wittgenstein
Authors: Misak Cheryl 
Published: June 2016

An underappreciated fact in the history of analytic philosophy is that American pragmatism had an early and strong influence on the Vienna Circle. The path of that influence goes from Charles Peirce to Frank Ramsey to Ludwig Wittgenstein to Moritz Schlick. That path is traced in this paper, and along the way some standard understandings of Ramsey and Wittgenstein, especially, are radically altered.

Abstract
Contreras, B, Vigotsky, AD, Schoenfeld, BJ, Beardsley, C, McMaster, DT, Reyneke, JHT, and Cronin, JB. Effects of a six-week hip thrust vs. front squat resistance training program on performance in adolescent males: A randomized controlled trial. J Strength Cond Res 31(4): 999–1008, 2017—The barbell hip thrust may be an effective exercise for increasing horizontal force production and may thereby enhance performance in athletic movements requiring a horizontal force vector, such as horizontal jumping and sprint running. The ergogenic ability of the squat is well known. The purpose of this study was to compare the effects of 6-week front squat and hip thrust programs in adolescent male athletes. Vertical jump height, horizontal jump distance, 10- and 20-m sprint times, and isometric midthigh pull peak force were among the measured performance variables, in addition to front squat and hip thrust 3 repetition maximum (3RM) strength. Magnitude-based effect sizes revealed potentially beneficial effects for the front squat in both front squat 3RM strength and vertical jump height when compared with the hip thrust. No clear benefit for one intervention was observed for horizontal jump performance. Potentially beneficial effects were observed for the hip thrust compared with the front squat in 10- and 20-m sprint times. The hip thrust was likely superior for improving normalized isometric midthigh pull strength and very likely superior for improving hip thrust 3RM and isometric midthigh pull strength. These results support the force vector theory.

Abstract
Liguori, G, Schuna, JM Jr, Tucker, J, and Fountaine, CM. Impact of prescribed exercise on physical activity compensation in young adults. J Strength Cond Res 31(2): 503–508, 2017—Army Reserve Officers' Training Corps cadets present a unique subpopulation because they are required to participate in regular physical activity (PA). This study describes PA patterns of cadets and attempts to identify evidence of nonexercise PA compensation (activitystat) as a result of prescribed PA (pPA) by comparing differences between training and nontraining days for (a) autonomous PA among cadets and (b) PA between cadets and noncadets. Participants included 84 university students (33 cadets and 51 noncadets) who each wore an accelerometer for 5 consecutive days to estimate moderate and vigorous physical activity (MVPA). A 2×2 mixed model analysis of variance was used to examine within- and between-group differences in MVPA on training and nontraining days. This analysis was repeated after removing the cadet's pPA. Cadets had lower-body fat than noncadets (p = 0.044), but all other characteristics were similar. Overall, moderate PA (MPA) and vigorous PA (VPA) were significantly greater among cadets (p = 0.048 and p < 0.001), because of greater weekend MPA (p = 0.021) and greater weekday VPA (p < 0.001). Cadets accumulated more MVPA on training days than nontraining days (p < 0.001) and accumulated more MVPA than noncadets on training days (p = 0.004). However, after accounting for pPA, cadet MVPA did not differ between training and nontraining days (within 1.2Â ± 18.4 min·d−1) and was similar between cadets and noncadets (within 1.5Â ± 5.9 min·d−1). These results suggest that cadets were significantly more active than noncadets due mainly to pPA. When controlling for pPA, cadets were similarly active across all days, and were as active as noncadets, indicating no evidence of activitystat in this population.
Broadband Electrophysiological Dynamics Contribute to Global Resting-State fMRI Signal
Authors: Wen Haiguang , Liu Zhongming 
Published: June 2016

Spontaneous activity observed with resting-state fMRI is used widely to uncover the brain's intrinsic functional networks in health and disease. Although many networks appear modular and specific, global and nonspecific fMRI fluctuations also exist and both pose a challenge and present an opportunity for characterizing and understanding brain networks. Here, we used a multimodal approach to investigate the neural correlates to the global fMRI signal in the resting state. Like fMRI, resting-state power fluctuations of broadband and arrhythmic, or scale-free, macaque electrocorticography and human magnetoencephalography activity were correlated globally. The power fluctuations of scale-free human electroencephalography (EEG) were coupled with the global component of simultaneously acquired resting-state fMRI, with the global hemodynamic change lagging the broadband spectral change of EEG by ∼5 s. The levels of global and nonspecific fluctuation and synchronization in scale-free population activity also varied across and depended on arousal states. Together, these results suggest that the neural origin of global resting-state fMRI activity is the broadband power fluctuation in scale-free population activity observable with macroscopic electrical or magnetic recordings. Moreover, the global fluctuation in neurophysiological and hemodynamic activity is likely modulated through diffuse neuromodulation pathways that govern arousal states and vigilance levels.SIGNIFICANCE STATEMENTThis study provides new insights into the neural origin of resting-state fMRI. Results demonstrate that the broadband power fluctuation of scale-free electrophysiology is globally synchronized and directly coupled with the global component of spontaneous fMRI signals, in contrast to modularly synchronized fluctuations in oscillatory neural activity. These findings lead to a new hypothesis that scale-free and oscillatory neural processes account for global and modular patterns of functional connectivity observed with resting-state fMRI, respectively.

Published: June 2016

Altered dopamine D2 receptor (D2R) binding in the striatum has been associated with abnormal motivation in neuropsychiatric disorders, including schizophrenia. Here, we tested whether motivational deficits observed in mice with upregulated D2Rs (D2R-OEdevmice) are reversed by decreasing function of the striatopallidal “no-go” pathway. To this end, we expressed the Gαi-coupled designer receptor hM4D in adult striatopallidal neurons and activated the receptor with clozapine-N-oxide (CNO). Using a head-mounted miniature microscope we confirmed with calcium imaging in awake mice that hM4D activation by CNO inhibits striatopallidal function measured as disinhibited downstream activity in the globus pallidus. Mice were then tested in three operant tasks that address motivated behavior, the progressive ratio task, the progressive hold-down task, and outcome devaluation. Decreasing striatopallidal function in the dorsomedial striatum or nucleus accumbens core enhanced motivation in D2R-OEdevmice and control littermates. This effect was due to increased response initiation but came at the cost of goal-directed efficiency. Moreover, response vigor and the sensitivity to changes in reward value were not altered. Chronic activation of hM4D by administering CNO for 2 weeks in drinking water did not affect motivation due to a tolerance effect. However, the acute effect of CNO on motivation was reinstated after discontinuing chronic treatment for 48 h. Used as a therapeutic approach, striatopallidal inhibition should consider the risk of impairing goal-directed efficiency and behavioral desensitization.SIGNIFICANCE STATEMENTMotivation involves a directional component that allows subjects to efficiently select the behavior that will lead to an optimal outcome and an activational component that initiates and maintains the vigor and persistence of actions. Striatal output pathways modulate motivated behavior, but it remains unknown how these pathways regulate specific components of motivation. Here, we found that the indirect pathway controls response initiation without affecting response vigor or the sensitivity to changes in the reward outcome. A specific enhancement in the activational component of motivation, however, can come at the cost of goal-directed efficiency when a sustained response is required to obtain the goal. These data should inform treatment strategies for brain disorders with impaired motivation such as schizophrenia and Parkinson's disease.
DNA Methyltransferase 1 Is Indispensable for Development of the Hippocampal Dentate Gyrus

Published: June 2016

Development of the hippocampal dentate gyrus (DG) in the mammalian brain is achieved through multiple processes during late embryonic and postnatal stages, with each developmental step being strictly governed by extracellular cues and intracellular mechanisms. Here, we show that the maintenance DNA methyltransferase 1 (Dnmt1) is critical for development of the DG in the mouse. Deletion ofDnmt1in neural stem cells (NSCs) at the beginning of DG development led to a smaller size of the granule cell layer in the DG. NSCs lackingDnmt1failed to establish proper radial processes or to migrate into the subgranular zone, resulting in aberrant neuronal production in the molecular layer of the DG and a reduction of integrated neurons in the granule cell layer. Interestingly, prenatal deletion ofDnmt1in NSCs affected not only the developmental progression of the DG but also the properties of NSCs maintained into adulthood:Dnmt1-deficient NSCs displayed impaired neurogenic ability and proliferation. We also found thatDnmt1deficiency in NSCs decreased the expression of Reelin signaling components in the developing DG and increased that of the cell cycle inhibitorsp21andp57in the adult DG. Together, these findings led us to propose that Dnmt1 functions as a key regulator to ensure the proper development of the DG, as well as the proper status of NSCs maintained into adulthood, by modulating extracellular signaling and intracellular mechanisms.SIGNIFICANCE STATEMENTHere, we provide evidence that Dnmt1 is required for the proper development of the hippocampal dentate gyrus (DG). Deletion ofDnmt1in neural stem cells (NSCs) at an early stage of DG development impaired the ability of NSCs to establish secondary radial glial scaffolds and to migrate into the subgranular zone of the DG, leading to aberrant neuronal production in the molecular layer, increased cell death, and decreased granule neuron production. Prenatal deletion ofDnmt1in NSCs also induced defects in the proliferation and neurogenic ability of adult NSCs. Furthermore, we found that Dnmt1 regulates the expression of key extracellular signaling components during developmental stages while modulating intracellular mechanisms for proliferation and neuronal production of NSCs in the adult.
