Laryngeal Mask Airway for Cesarean Delivery: A 5-Year Retrospective Cohort Study
No full textBackground: The laryngeal mask airway (LMA) is the most commonly used rescue airway in obstetric anesthesia. The aim of this retrospective cohort study was to evaluate the application of the LMA in parturients undergoing cesarean delivery (CD) for 5 years in our hospital. As a secondary objective, we investigated the incidence of airway-related complication in obstetric general anesthesia (GA).
Methods: We collected electronic data for all obstetric patients who received GA for CD between January 2010 and December 2014 in Peking University First Hospital. Based on the different types of airway device, patients were divided into endotracheal intubation (ET) group and LMA group. The incidences of regurgitation and aspiration, as well as maternal and neonatal postoperative outcomes were compared between groups.
Results: During the 5-year study, GA was performed in 192 cases, which accounted for 2.0% of all CDs. The main indications for GA were contraindication to neuraxial anesthesia or a failed block. Among these, ET tube was used in 124 cases (68.9%) and LMA in 56 cases (31.1%). The percentage of critical patients above the American Society of Anesthesiologists' Grade II was 24/124 in ET group and 4/56 in LMA group (P = 0.036). The emergent delivery rate was 63.7% for ET group and 37.5% for LMA group (P = 0.001). None of the patients had regurgitation or aspiration. There were no significant differences in terms of neonatal Apgar scores, maternal and neonatal postoperative outcomes between the two groups.
Conclusions: Our results suggested that GA was mainly used for contraindication to neuraxial anesthesia or a failed block, and emergent CDs accounted for most cases. The second-generation LMA could be used for obstetric anesthesia, but correct position to achieve a good seal is the key to prevent reflux and aspiration. Whether they could replace the tracheal tube in routine practice needs further large prospective studies
Two new species and a new record of the Encarsia longifasciata-group (Hymenoptera, Aphelinidae) from Malaysia and China
No full textThe genus Encarsia Förster, 1878, which is the largest genus of the family Aphelinidae, contains 453 valid species worldwide. Most species of Encarsia with known biology are primary endoparasitoids of Aleyrodidae and Diaspididae.
Species of the Encarsia longifasciata-group from Malaysia and China are reviewed. This is the first record of this group from Malaysia. Two new species, E. borneensis Geng & Li sp. n. and E. pauroseta Geng & Li sp. n., are described and illustrated. Encarsia longifasciata is newly recorded from Malaysia (Borneo). An updated key to the longifasciata-group species (females) worldwide is provided.Copyright © Geng H et al.

Ship Scheduling in Inland Waterway Networks Based on Cellular Automata Graph
No full textThis paper presents models and algorithms for vessel scheduling based on a graph model of inland waterway networks. In particular, it models the waterway networks by a directed graph, G = (V, E, W), where the node set V represent the harbors and the cross points of the waterways; the arc set E represent the river segments between the cross points and the weight set W represent the shipping capacity of each arc, in terms of how many ships can travel through the given waterway segment in a fixed time interval. The graph model is a simplified model of cellular automata. The difference is that the shipping capacity is modeled not only as a function of the specific conditions of the waterway segment, but also as a function of the volumes and real-time velocities of vessels. So that the capacity model is parameterized. Then, based on the simplified cellular automata model, a scheduling algorithm for minimizing the transportation time of a set of vessels with given routes are proposed, which is evaluated by simulations.National Key Technology Support Program [2014BAK12B06, 2015BAG20B02]CPCI-S(ISTP)450-45

Meta-analysis of summary statistics versus individual participant-level data of trials with binary outcomes
No full textDissertation (MSc (Advanced Data Analytics))--University of Pretoria, 2022.In this essay we will consider the meta-analysis of summary statistics versus individual participant-level data of trials with binary outcomes. Numerous techniques will be considered to essentially determine, both theoretically as well as numerically, by the use of real data analysis, whether or not, in certain instances, analyzing individual participant data (IPD) from all investigations undoubtedly gains efficiency over combining summary statistics from each study in a binary setting. We will be considering both the one-step as well as two-step meta-analysis, with the focus being mainly on the standard fixed-effects model and partially on the random-effects model. An application of two different clinical studies will be considered. The first study is called the Cannon (Cannon et al., (2006)[13]) Cardiovascular Clinical Trials which consists of four clinical studies. The second study is called the Bacillus Calmette-Guerin Vaccine Study which consists of a total of 13 clinical studies. We observed that a meta-analysis of summary data is more similar to a meta-analysis of IPD data for the first study, but different for the second study. This is due to the fact that the number of studies
are small in both studies. Therefore the asymptotic equivalence should be cautious when the sample size is small and the number of studies is small. In this case, the estimation of the between study variance will be very unstable which will lead to a different conclusion between a meta-analysis of summary statistics (SS) and a meta-analysis of individual participant-level (IPD) data.This work is based upon research supported by the National Research Foundation, South Africa (South Africa DST-NRF-SAMRC SARChI Research Chair in Biostatistics to Professor Ding-Geng Chen, Grant number 114613).

Bounds on Direct and Indirect Effects of Treatment on a Continuous Endpoint
No full textDirect effect of a treatment variable on an endpoint variable and indirect effect through a mediate variable are important concepts for understanding a causal mechanism. However, the randomized assignment of treatment is not sufficient for identifying the direct and indirect effects, and extra assumptions and conditions are required, such as the sequential ignorability assumption without unobserved confounders or the sequential potential ignorability assumption. But these assumptions may not be credible in many applications. In this article, we consider the bounds on controlled direct effect, natural direct effect, and natural indirect effect without these extra assumptions. Cai et al. [2008] presented the bounds for the case of a binary endpoint, and we extend their results to the general case for an arbitrary endpoint.NSFC [11171365, 11331011]; 863 Program [2015AA020507]; 973 Program [2015CB856000]; Center for Statistical Science, Peking UniversitySCI(E)[email protected]; [email protected],SI
Biologic function and clinical potential of telomerase and associated proteins in cardiovascular tissue repair and regeneration
No full textTelomeres comprise long tracts of double-stranded TTAGGG repeats that extend for 915 kb in humans. Telomere length is maintained by telomerase, a specialized ribonucleoprotein that prevents the natural ends of linear chromosomes from undergoing inappropriate repair, which could otherwise lead to deleterious chromosomal fusions. During the development of cardiovascular tissues, telomerase activity is strong but diminishes with age in adult hearts. Dysfunction of telomerase is associated with the impairment of tissue repair or regeneration in several pathologic conditions, including heart failure and infarction. Under both physiologic and pathophysiologic conditions, telomerase interacts with promyogenic nuclear transcription factors (e.g. myocardin, serum response factor) to augment the potency of cardiovascular cells during growth, survival, and differentiation. We review recent findings on the biologic function of telomerase and its potential for clinical application in cardiovascular development and repair. Understanding the roles of telomerase and its associated proteins in the functional regulation of cardiovascular cells and their progenitors may lead to new strategies for cardiovascular tissue repair and regeneration. © The Author 2010
Collapsibility for Directed Acyclic Graphs
No full textCollapsibility means that the same statistical result of interest can be obtained before and after marginalization over some variables. In this paper, we discuss three kinds of collapsibility for directed acyclic graphs (DAGs): estimate collapsibility, conditional independence collapsibility and model collapsibility. Related to collapsibility, we discuss removability of variables from a DAG. We present conditions for these three different kinds of collapsibility and relationships among them. We give algorithms to find a minimum variable set containing a variable subset of interest onto which a statistical result is collapsible.
