A prospective study of postpartum psychoses in a high‐risk group

ABSTRACT— Among 88 reproductions to women with a history of nonorganic psychosis, 25 postpartum episodes (PPPs) occurring during the total 6‐month period following the current delivery were not systematically related to the woman's demographic characteristics, to her psychiatric history characteristics surrounding onset of the previous disorder or to a history of PPPs following previous reproductions. PPPs were highly significantly related to greater length of previous psychiatric hospitalization and to active mental disturbance just prior to this pregnancy, and this was true both for PPPs developing within 3 weeks of delivery and for those developing later. Considerable differences were found in the demographic characteristics that were related to development of PPPs within these Early vs. Later Onset cases, suggesting these to represent different disorders not only diagnostically but also demographically. In several diagnostic categories, selected demographic or psychiatric history characteristics identified subgroups with PPP rates as high as 75%.
TCAD Studies on the Determination of Diffusion Length for the Planar-Collector EBIC Configuration With Any Size of the Schottky Contact

In this brief, the transient single-contact electron-beam-induced current (SC-EBIC) and the conventional steady-state EBIC modes of the planar-collector configuration that were studied using a Technology Computer Aided Design device simulator are presented. The feasibility of these EBIC data in the extraction of the diffusion length of the planar-collector configuration with any values of surface recombination velocities and any size of the Schottky contact is also presented. The effect of the size of the Schottky contact on steady state and transient EBIC signals as well as the extracted diffusion length and linearization coefficient is discussed in this brief. The EBIC information obtained from the SC-EBIC and the conventional EBIC is found to be able to evaluate the diffusion length accurately regardless of the size of the Schottky contact.
The Value of Adding Transcutaneous Neuromuscular Electrical Stimulation (VitalStim) to Traditional Therapy for Poststroke Dysphagia: A Randomized Controlled Trial

Background: Dysphagia may delay the functional recovery and substantially affects the quality of life after stroke, mainly if left untreated. Electrical stimulation has been reported as a treatment for pharyngeal dysphagia in recent studies, but the therapeutic effect of neuromuscular electrical stimulation (VitalStim) therapy lacks convincing supporting evidence and needs further clinical investigation. Methods: A total of 135 subjects were randomly divided into 3 groups: traditional swallowing therapy (n = 45), VitalStim therapy (n = 45), and VitalStim therapy plus traditional swallowing therapy (n = 45). The traditional swallowing therapy included basic training and direct food intake training. Electrical stimulation was applied by an occupational therapist, using a modified handheld battery-powered electrical stimulator (VitalStim Dual Channel Unit and electrodes, Chattanooga Group, Hixson, Tennessee). The surface electromyography (sEMG), standardized swallowing assessment (SSA), videofluoroscopic swallowing study (VFSS), and visual analog scale (VAS) were used to assess swallowing function before and 4 weeks after the treatment. Results: A total of 118 subjects with dysphagia completed the study, 40 in the traditional swallowing group and VitalStim therapy group and 38 in the VitalStim and traditional swallowing therapy group. There were significant differences in sEMG values and SSA and VFSS scores in each group after the treatment (P < .001). After 4-week treatment, sEMG value (917.1; standard deviation [SD], 91.2), SSA value (21.8; SD, 3.5), oral transit time (0.4; SD, 0.1), and pharyngeal transit time (0.8; SD, 0.1) were significantly improved in the VitalStim and traditional swallowing therapy group than in the other 2 groups (P < .001). Conclusions: Data suggest that VitalStim therapy coupled with traditional swallowing therapy may be beneficial for poststroke dysphagia.
Consensus community detection for multi-dimensional networks

Since their beginnings, social networks have affected the way people communicate and interact with each other. Nowadays, user interactions range from social relations to posting and reading activities, leading to the existence of multiple and complementary information sources or dimensions for characterising user behaviour. The task of community detection could benefit from integrating those multiple sources. However, most techniques disregard the effect of information aggregation, and continue to focus only on one aspect: network topology. This paper aims at providing some insights on how to integrate the multiple and heterogeneous social media information sources characterising user activities and behaviour to optimise the quality of found communities. To that end, diverse consensus strategies to extend techniques designed for a unique information source to multi-dimensional networks are presented and analysed. Experimental evaluation confirmed the benefits of using consensus strategies for leveraging on multiple data dimensions in terms of community quality.
Année académique 2008-2009 Working paper 09 / 28 Exploring the boundaries of intermediaries : An attempt to bridge the gap between value configuration and organizational architecture

Few studies have explicitly examined the importance that a specific and unusual value configuration of a firm has on the architectural design of the same firm and vice-versa. In this paper we argue that firm-level value creation logic and organizational architecture are closely inter-related. More specifically, we suggest that considering matchmaking forms of market intermediation as value networks, allows one to deepen its understanding of how mediating firms –in opposition with manufacturing firms– shape their organizational boundaries. Using data on eBay Inc., we show that value configuration interacts with network embeddedness to determine organizational boundary decisions. Finally, as this is a first attempt to link value configuration analysis to the organizational architecture literature, we call for further empirical work to validate the results of this exploratory study.
The influence of combination use of CYP450 inducers on the pharmacokinetics of voriconazole: a systematic review

Voriconazole is a triazole antifungal agent and is extensively metabolized via cytochrome P450 (CYP450); therefore, special precautions need to be taken when co‐administered with a known CYP450 inducer, which may lead to treatment failure. The influence of some CYP450 inducers on the pharmacokinetics of voriconazole has been described in previous studies, but a systematic review was lacking. In this study, we carried out a systematic review to assess the influence of CYP450 inducers on the pharmacokinetic (PK) parameters of voriconazole.
Evaluation of CPS ID2 medium for detection of urinary tract bacterial isolates in specimens from a rehabilitation center

CPS ID2 medium (bioMérieux) enables the presumptive identification of Escherichia coli and enterococci as well as the detection of indologenous or nonindologenous Proteeae and bacteria belonging to the Klebsiella, Enterobacter, and Serratia group with a specificity ranging from 98 to 100%. When the cultures were polymicrobial, the sensitivity varied from 70 to 97%, and the sensitivity varied from 97 to 100% when they were monomicrobial.
Pre‐ and Postoperative Auditory Event‐Related Potentials in Temporal Lobe Epilepsy

Summary: We studied auditory event‐related potentials (ERPs) in 11 surgically treated patients with intractable temporal lobe epilepsy (TLE) pre‐ and postoperatively. ERPs through sphenoidal electrodes (Sp1‐T3, Sp2‐T4) provided clinically relevant and correctly lateralizing electrophysiologic evidence of temporal lobe dysfunction in 9 of 11 patients, confirmed by EEGs, electrocorticograms, neuroradiologic, and neuropsychological results, and clinical follow‐up. Lateralizing asymmetries were noted in P300 amplitude, but latencies were prolonged bilaterally. Sphenoidal ERPs might serve as a new functional indicator of temporal lobe dysfunction in patients evaluated for epilepsy surgery.
On the use of LMMSE receiver for single and multiple packet reception in stabilized multi-channel slotted aloha

This paper models a multi-channel stabilized S-Aloha system with capture. A capture model for single packet reception in a multi-carrier stabilized S-Aloha network is first proposed. This model can be effectively used for both single and multiple antenna base station (BS). A multi-packet reception model is also developed for multi-antenna base stations. In this model, the base station can use any multiuser detection algorithm. Two frame structures are used to allow multiuser detection. An ideal multiuser detector (MUD), i.e. the number of successful users is less than or equal to the number of antennas at the the BS, is considered in this paper. It is shown that for a lightly loaded system, i.e. when rate of new packet generation in the network is low, there might not be enough advantage to use a multiple antenna system in terms of throughput. It is also shown that in a finite user case the maximum attainable stabilized throughput reduces slightly with increasing number of users and very quickly reaches the infinite user case.
Efficient Plurality Consensus, Or: the Benefits of Cleaning up from Time to Time

Plurality consensus considers a network of n nodes, each having one of k opinions. Nodes execute a (randomized) distributed protocol with the goal that all nodes adopt the plurality (the opinion initially supported by the most nodes). Communication is realized via the Gossip (or random phone call) model. A major open question has been whether there is a protocol for the complete graph that converges (w.h.p.) in polylogarithmic time and uses only polylogarithmic memory per node (local memory). We answer this question affirmatively. We propose two protocols that need only mild assumptions on the bias in favor of the plurality. As an example of our results, consider the complete graph and an arbitrarily small constant multiplicative bias in favor of the plurality. Our first protocol achieves plurality consensus in O(logk·loglogn) rounds using logk + Θ(loglogk) bits of local memory. Our second protocol achieves plurality consensus in O(logn·loglogn) rounds using only logk + 4 bits of local memory. This disproves a conjecture by Becchetti et al. (SODA'15) implying that any protocol with local memory logk+O(1) has worst-case runtime Ω(k). We provide similar bounds for much weaker bias assumptions. At the heart of our protocols lies an undecided state, an idea introduced by Angluin et al. (Distributed Computing'08).
Antidiabetic and Antioxidant Activities of Zizyphus lotus L Aqueous Extracts in Wistar Rats

Objectives: Zizyphus lotus L. is a medicinal plant, used in traditional medicine for its multiple therapeutic properties. The aim of the present study was to determine the antidiabetic and antioxidant effects of aqueous extracts of different parts of Zizyphus lotus in diabetic Wistar rats. Research methods and procedures: The male Wistar rats were rendered diabetic by intraperitoneal (i.p.) injection of streptozotocin (40 mg/kg body weight). Aqueous extracts from different parts, i.e, root, leaf, and seed of Zizyphus lotus L. were prepared and administrated orally to the animals at the dose of 300 mg/kg for 21 days. Blood glucose level was measured, and antioxidant status was assessed by determining oxygen radical absorbance capacity (ORAC) and the activities of enzymes like catalase, glutathione reductase and peroxidase in pancreas, liver, and erythrocytes. Vitamin C levels were determined by precipitating with 10% trichloroacetic acid. Vitamins A and E concentrations were measured by HPLC. Results: The leaf and root, but not seed, extracts exerted the glucose lowering effect on 21st day of postadministration. The leaf and root extracts corrected antioxidant status of diabetic animals in pancreas, liver and erythrocytes. The concentrations of different vitamins (vitamin A, C and E) in diabetic rats were also modulated by leaf and root, but not seed, extracts. Conclusion(s): Our study shows that oral administration of Zizyphus lotus L. extracts from roots and leaves exerted antidiabetic and antioxidant effects in diabetic rats. Z. lotus L. seems to be a good candidate to lower, in addition to conventional antidiabetic drugs, the hyperglycaemia in diabetic subjects.
Poster: A new approach to the Main Problem of Subspace Coding

Subspace codes form the appropriate mathematical setting for investigating the Koetter-Kschischang model of fault-tolerant network coding. The Main Problem of Subspace Coding asks for the determination of a subspace code of maximum size (proportional to the transmission rate) if the remaining parameters are kept fixed. We describe a new approach to finding good subspace codes, which surpasses the known size limit of lifted MRD codes and is capable of yielding an alternative construction of the currently best known binary subspace code of packet length 7, constant dimension 3 and minimum subspace distance 4.
Seafloor receiver function analysis for hybrid dataset composed of both refraction survey and earthquake records

In this study, we present two types of simulation models that consist of a sediment layer, a crust layer, and a sloped interface that are marked as seismic velocity discontinuities. Seismometers are aligned on the seafloor. One model has only surface seismic sources and the other has buried seismic sources that are equivalent to natural earthquakes. For every shot or earthquake, we obtain either refracted or converted waves from the velocity interfaces. We estimate a receiver function for each shot or earthquake for our sub-seafloor structural analysis. After these processing, the receiver function analysis is justified to estimate velocity interface and the applicable method of refraction wave analysis. For the first models, we confirmed that our receiver function could estimate the depth and shape of the velocity interface precisely. The refracted waves propagate beneath the velocity interfaces and generate both refracted compressional and converted shear waves that are used to estimate receiver functions at each location of seismometers. Our result indicates that the receiver function analysis can be applied to refraction seismic survey data using artificial seismic sources located near the surface above the target structure. Finally, we include seismic records from the buried sources in our receiver function analysis, and combine results from refraction survey and conventional earthquake data. Although data processing such as seismic migration becomes necessary, our results demonstrate that receiver function analysis can be applied not only for conventional earthquake records but also for artificial seismic surveys. Our analysis to synthetic data demonstrates the effectiveness of the method and the necessity of fair wave decomposition techniques to separate both compressional and shear waves from observed wavefield.
Virus‐specific major MHC class II‐restricted TCR‐transgenic mice: effects on humoral and cellular immune responses after viral infection

A transgenic mouse expressing MHC class II‐restricted TCR with specificity for a lymphocytic choriomeningitis virus (LCMV) glycoprotein‐derived T helper cell epitope was developed to study the role of LCMV‐specific CD4+ T cells in virus infection in vivo. The majority of CD4+ T cells in TCR transgenic mice expressed the transgenic receptor, and LCMV glycoprotein‐specific TCR transgenic CD4+ T cells efficiently mediated help for the production of LCMV glycoprotein‐specific isotype‐switched antibodies. In contrast, LCMV glycoprotein‐specific TCR transgenic mice exhibited a drastically reduced ability to provide help for the generation of antibody responses specific for the virus‐internal nucleoprotein, indicating that intramolecular/intrastructural help is limited to antigens that are accessible to B cells on the viral surface. Antiviral cellular immunity was studied with noncytopathic LCMV and recombinant cytopathic vaccinia virus expressing the LCMV glycoprotein. TCR transgenic mice failed to efficiently control LCMV infection, demonstrating that functional LCMV‐specific CD4+ T cells – even if activated and present at extremely high frequencies – cannot directly mediate protective immunity against LCMV. Despite the fact that LCMV‐primed CD4+ T cells from TCR transgenic mice as well as from control mice showed low MHC class II‐restricted cytotoxic activity in vivo, this did not correlate with protection against LCMV replication in vivo. In contrast, CD4+ T cells from TCR‐transgenic mice mediated efficient protection against infection with recombinant vaccinia virus. These results further support the need for different immune effector functions for protective immunity against different viral infections.
Uncovering unusual mortality differentials in Russia and Kazakhstan ∗

Research on global mortality has exhaustively documented a Russian mortality paradox— the phenomenon of populations of Slavic descent in experiencing higher adult mortality despite higher socioeconomic status. This study exploits Kazakhstan’s relatively heterogeneous population and geographic diversity to study ethnic differences in cause-specific mortality. After controlling for contextual differences, all-cause mortality rates for Russian men remains 27% higher than for Kazakh men, and alcohol-related death rates among Russian men remain 2.5 times higher (15% and 4.1 times higher for females, respectively). Significant mortality differentials exist by ethnicity for external causes and alcohol-related causes of death. Adult mortality among Kazakhs is higher than previously found among Kyrgyz and lower than among Russians. This phenomenon suggests the existence of a continuum between ’non-Russian’ and ’Russian’ model mortality patterns based on degree of accord to documented patterns of alcohol consumption among Russians. Differential mortality across republics of Central Asia may improve our understanding of the Russian mortality paradox.
A Distributed Approach for the Analysis of Discussions in Twitter

In a recent work we have developed an argumentative approach for discovering relevant opinions in Twitter. A Twitter discussion is modeled as a weighted argument graph where each node denotes a tweet, each edge denotes a criticism relationship between a pair of tweets of the discussion and each node is attached with a weight that denotes the social relevance of the corresponding tweet in the discussion. In the social network Twitter, a tweet always refers to previous tweets in the discussion, so the obtained underlying argument graph is acyclic. Based on this structural feature, in this work, we introduce a distributed algorithm for computing the set of globally accepted opinions of a Twitter discussion. The set of accepted opinions is extracted by mapping the weighted argument graph into a valued argumentation framework and it is computed as the biggest set of tweets of the discussion that satisfies that it is consistent. 1 Motivation and Antecedents In order to understand what are the major accepted and rejected opinions in different domains by Twitter users, in a recent work [1] we have developed a system for analysis of discussions in Twitter. The system architecture has two main components: a discussion retrieval and a reasoning system. The discussion retrieval component allows us to move from ?

Selecting stable route in multipath routing protocols

Link failure due to node mobility is routine in mobile ad hoc networks (MANETs). A standard approach to deal with such failures is to select stable routes instead of the shortest route. However, protocols that select stable route do not attempt to optimize the number of hops and hence do not guarantee improvement in performance. Another approach to handle mobility induced route failure is multipath reactive protocols. These protocols start forwarding the packet on the first available route and switches path when a route failure is detected. Although these multipath protocols save on route rediscovery overhead, we establish that they still incur a substantial overhead called route handover cost, while switching among the alternate paths. In this work, we propose a light weight metric link lifetime, which helps to choose a stable path in multipath protocols. We incorporate link lifetime in standard multipath protocol and show that it reduces routing overhead and consequently improves throughput.
Medication treatment strategies in the MTA Study: relevance to clinicians and researchers.

OBJECTIVE Clinicians have difficulty applying drug research findings to clinical practice, because research protocols use methods different from those used in daily office practice settings. METHOD To design a medication protocol for a multisite clinical trial involving 576 children with attention-deficit hyperactivity disorder (ADHD) while maintaining relevance to clinical practice, investigators from the NIMH Collaborative Multisite Multimodal Treatment Study of Children with Attention-Deficit/Hyperactivity Disorder (MTA study) developed novel medication strategies. These were designed to work either in a monomodal or multimodal format and to ensure standard approaches are used across diverse sites. Each child randomized to medication (projected N = 288) is individually titrated to his or her "best" methylphenidate dose and has individual ADHD symptoms monitored. Decision rules were developed to guide "best dose" selection, dose changes, medication changes, the management of side effects, and integration with psychosocial treatments. CONCLUSIONS The MTA study uses a controlled method to standardize the identification of each child's "best" methylphenidate dose in a national, multisite cooperative treatment program. Although the titration protocol is complex, the study's individual dosing approach and algorithms for openly managing ADHD children's medication over time will be of interest to clinicians in office practice.
Admission Control of Video Sessions over Ad Hoc Networks Using Neural Classifiers

The paper proposes an adaptive, distributed admission control scheme for the execution of VBR video sessions over ad hoc networks with heterogeneous video and HTTP traffic. The key idea of the proposed scheme is the use of probabilistic radial basis classifiers, which are specialized types of neural networks. Firstly, the admission control function is defined analytically. Afterwards, the neural network that implements the scheme is set up. Lastly, a thorough, comparative performance evaluation through simulation is performed. Results show that the proposed scheme outperforms state of the art admission control algorithms.
