Effectiveness of clinical pathway teaching combine OSCE in the training of new ICU nurses:a quasi-experimental study

Field: Health Professions (Health Sciences)

Abstract

Background To explore effectiveness of clinical pathway teaching combine OSCE in the training of new ICU nurses.Methods To selected 52 new nurses who joined ICU of Peking University Shenzhen hospital from August 2020 to January 2022, and divided the subjectsc ronological into two groups. The experimental group used the clinical pathway teaching and combined with the OSCE evaluation, while the control group took the routine training method and assessment method. Used the 6-D scale and the CNCQ to collect new ICU nurses’data before and after a two-month cycle training.Results In this study, the average score of the theoretical exam in experimental group was 85.72 (76.00,94.00), which is higher than control group( 78.98 (73.00,84.00)), The difference was significant (P < 0.05). New nurses of experimental group had higher scores on the CNCQ’s items after training(93.46 ± 11.20)than before(75.46 ± 11.19), differences were statistically significant(P < 0.001). There was astatistical difference(P = 0.024) in the scores of control group before(85.92 ± 12.19) and after(93.46 ± 11.20) training. New nurses of experimental grouphad higher scores on the 6-D scale’s items after training(185.00 ± 39.98)than before(154.19 ± 38.32), differences were statistically significant(P < 0.05). However, there was no statistical difference in the scores of control group before and after training.Conclusion Clinical pathway teaching combined with OSCE can improve the theoretical knowledge level and clinical comprehensive ability of new ICU nurses, and promote good nursing behaviour for them. Recognition of ability toplayin the nursing pos can affect their nursing behavior. Clinical pathway teaching combined with OSCE can fill the gap in nursing behaviours before and after training, such as nurse teaching collaboration, planning/evaluation, interpersonal communication, professional development. But the improvement of leadership and critical care ability still need enough clinical practice.
Synthetic dual image generation for reduction of labeling efforts in semantic segmentation of micrographs with a customized metric function

Field: Computer Science (Physical Sciences)

Abstract Training of semantic segmentation models for material analysis requires micrographs as the inputs and their corresponding masks. In this scenario, it is quite unlikely that perfect masks will be drawn, especially at the edges of objects, and sometimes the amount of data that can be obtained is small, since only a few samples are available. These aspects make it very problematic to train a robust model. Therefore, we demonstrate in this work an easy-to-apply workflow for the improvement of semantic segmentation models of micrographs through the generation of synthetic microstructural images in conjunction with masks. The workflow only requires joining a few micrographs with their respective masks to create the input for a Vector Quantised-Variational AutoEncoder (VQ-VAE) model that includes an embedding space, which is trained such that a generative model (PixelCNN) learns the distribution of each input, transformed into discrete codes, and can be used to sample new codes. The latter will eventually be decoded by VQ-VAE to generate images alongside corresponding masks for semantic segmentation. To evaluate the quality of the generated synthetic data, we have trained U-Net models with different amounts of these synthetic data in conjunction with real data. These models were then evaluated using real microscopic images only. Additionally, we introduce a customized metric derived from the mean Intersection over Union (mIoU) that excludes the classes that are not part of the ground-truth mask when calculating the mIoU of all the classes. The proposed metric prevents a few falsely predicted pixels from greatly reducing the value of the mIoU. With the implemented workflow, we were able to achieve a time reduction in sample preparation and acquisition, as well as in image processing and labeling tasks. The idea behind this work is that the approach could be generalized to various types of image data such that it serves as a user-friendly solution for training models with a smaller number of real images.

A flexible PCA-based ECG-reconstruction algorithm with confidence estimation for ECG during exercise

Field: Engineering (Physical Sciences)

Holter monitoring of the electrical activity of the heart is the key for analysis of many intermittent cardiac irregularities. The measurements are however prone to movement artifacts or poor skin-electrode contact, often making some parts of the recorded signals useless since important information might be hidden by these artifacts. In this paper a special ECG sensor node with active electrodes is used to record the 12-channel ECG during movement. Several methods for detection of degraded signal quality are combined and adapted to identify leads that have been compromised on a beat-to-beat level. A PCA-based reconstruction algorithm is then used to reconstruct leads with insufficient signal quality using only undisturbed leads. Furthermore this approach enables an estimation of the quality of reconstruction even in absence of an undisturbed reference.
Empirical Bayes procedures in time series analysis

Field: Mathematics (Physical Sciences)

Empirical Bayes analysis concerns the analysis of data which occur in similar recurring situations. The parameters involved in the recurring situations are generated independently from an unknown probability distribution G(θ). In many situations it is possible to use the estimates of all of the past parameter values to construct an estimate which reduces the mean squared error of the usual estimate of the present value of the parameter. \n\nThis dissertation involves the empirical Bayes estimates of various time series parameters: the auto-regressive time series model, the time series regression model with auto-correlated errors and the spectral density function. In each case, empirical Bayes estimators are obtained using asymptotic or approximate distributions of the usual estimators. The Parzen, Tukey and Bartlett smoothing coefficients are all used in the estimation of the spectral density function. Each estimator is tested on a high speed computer using Monte Carlo procedures. \n\nIt was found that in every situation the empirical Bayes estimators produced smaller mean squared errors than the usual estimator.
Retrospective analysis of leukemoid reactions in extremely preterm infants in a tertiary NICU from 2018–2021

Field: Medicine (Health Sciences)

Leukemoid reaction in ELBW infants with evidence of maternal and fetal inflammatory response syndrome on placental histology is associated with a longer duration of initial ventilation, increased need for inotropes in the first 72 h after birth, higher rates of death, and BPD. Prospective studies are required to identify potential biomarkers such as proinflammatory cytokines, IL-6, which might aid the decision-making process in delivery.
Generating processors from specifications of instruction sets

Field: Computer Science (Physical Sciences)

Viele digitale Systeme beinhalten Mikroprozessoren, weil sie aufgrund ihrer Programmierbarkeit sehr flexibel einsetzbar sind. Einige dieser Mikroprozessoren sind auf den jeweiligen Anwendungsbereich zugeschnitten, um die Ausführungsgeschwindigkeit von Programmen zu steigern und Energie zu sparen. Eine effiziente Entwicklung solcher anwendungsspezifischer Prozessoren bedarf geeigneter Entwicklungswerkzeuge. Dazu trägt diese Arbeit, sowohl durch die Spezifikationssprache ViDL, als auch durch zwei Generatoren zur schnellen Entwicklung anwendungsspezifischer Prozessoren bei. Ein Entwickler spezifiziert einen Instruktionssatz in ViDL und generiert daraus sowohl einen Simulator, als auch eine mikroarchitektonische Implementierung eines Prozessors. Um die praktische Anwendbarkeit von ViDL zu demonstrieren, wurden reale Instruktionssätze wie ARM, MIPS, Power und CoreVA spezifiziert und entsprechende Simulatoren und Prozessoren generiert. Generierte Prozessoren erreichen eine Geschwindigkeit von ca. 600MHz für eine 65 nm STMicroelectronics low power Technologie. Der Prozessorgenerator erzeugt eine n-stufige Pipeline, wobei n automatisch anhand einer vom Benutzer gegebenen Zielfrequenz ermittelt wird (z.B. 600MHz). Folglich können ohne zusätzlichen Aufwand verschiedenste mikroarchitektonische Implementierungen generiert werden. Alle Prozessoren und der Simulator sind garantiert konsistent, weil sie vollautomatisch aus derselben Spezifikation erzeugt werden. Die Eignung ViDLs zur Exploration von Entwurfsräumen und Erweiterung von Instruktionssätzen wurde durch die Entwicklung eines anwendungsspezifischen Prozessors im Rahmen dieser Arbeit nachgewiesen. Der Prozessor namens DNACore basiert auf MIPS und wurde durch einen Satz anspruchsvoller SIMD Instruktionen erweitert, die die Ausführung des Smith-Waterman Algorithmus erheblich beschleunigen.
Bereavement, Storytelling, and Reconciliation: Peacebuilding Between Israelis and Palestinians

Field: Social Sciences (Social Sciences)

Despite the ongoing conflict and the general neglect by the media, power brokers, and the public, grassroots organizations in the Middle East persist in their dedication to “people to people” diplomacy between Israelis and Palestinians. The Parents Circle-Families Forum is a bi-national NGO committed to peacebuilding and reconciliation between Jewish Israelis and Palestinians from East Jerusalem and the West Bank. Its most distinctive features are its membership, composed of 300 families from each side who have lost a close relative to the conflict, and its use of storytelling to connect the two sides. Bereaved individuals develop the capacity for empathy and moral responsibility beyond their own people by encountering “the other” via personal stories of loss and suffering. In pairs, Palestinian and Israeli members then share these stories with students in each society, modeling compassion and human solidarity, in an effort to bring about social transformation. This paper, based on ethnographic research recently conducted in Israel and the West Bank, considers the moral dynamics of these encounters and presentations, and their potential contribution to reconciliation and conflict transformation.
Sequence variation in the human dopamine transporter gene in subjects with bipolar disorder

Field: Biochemistry, Genetics and Molecular Biology (Life Sciences)

The dopamine (DA) transporter (hDAT, SLC6A3) plays a critical role in terminating synaptic DA neurotransmission and maintaining DA homeostasis. Dysfunction of hDAT is believed to contribute to various neuropsychiatric disorders such as attention deficit hyperactivity disorder (ADHD), schizophrenia, and bipolar disorder (BPD). Recently, we identified a rare hDAT variant, Ala559Val, in two ADHD subjects, which has also been identified in a subject with BPD [Grunhage et al., 2000]. In this study, we are evaluating whether functional variants in hDAT exist in BPD and ascertain the transmission pattern and functional nature of identified polymorphisms. We utilize PCR and temperature‐gradient capillary electrophoresis (TGCE) to screen for mutations in the entire coding region and adjacent non‐coding sequence of the hDAT gene in a cohort of >400 BPD (Type 1 and II) subjects. Preliminary analyses reveal a number of both novel and common single nucleotide polymorphisms (SNPs) across the gene. Our study constitutes the largest analysis to date of DAT coding sequences in BPD, permitting the identification of both common and rare variants that could contribute to DAT dysfunction in the disorder.

NMR and Modeling Studies of a Synthetic Extracellular Loop II of the κ Opioid Receptor in a DPC Micelle

Field: Chemistry (Physical Sciences)

This paper provides the first direct experimental evidence for the secondary structural features of the putative second extracellular loop (ECL II) of the kappa opioid receptor through a synthetic peptide mimic in a DPC micelle environment. These studies indicate that residues V(6)-A(15) of the ECL II peptide adopt a well-defined helical structure analogous to that formed by V(201)-C(210) of the native receptor. Moreover, a beta-turn around the D(22) (D(217)) and D(23) (D(218)) residues represents another feature of the ECL II. The NMR and fluorescent data also suggest the location of the two helical turns of TM V and the approximate location of the C-terminal end of the TM IV of the kappa opioid receptor. We modeled the kappa opioid receptor including the extracellular region of the receptor. The model of the ECL II utilized the information obtained from the NMR structural analysis of the ECL II peptide in a DPC micelle solution and the molecular dynamic simulations in a biphasic membrane environment. Our discovery of this amphiphilic helical region in the ECL II peptide by NMR and molecular modeling studies provides direct evidence that the sequence of residues V(201)-C(210) is likely to be the helical region that interacts with Dynorphin (Dyn) A [Paterlini, G., Portoghese, P. S., and Ferguson, D. M. (1997) J. Med. Chem. 40, 3254-3262]. We believe that this work offers further insight into the structural characteristics of the extracellular portions of the seven-TM kappa opioid receptor.
Effects of Rams and Luteal or Follicular Phase Ewes on Preovulatory LH Surge Characteristics in Ewes

Field: Agricultural and Biological Sciences (Life Sciences)

This study aimed to investigate whether the preovulatory LH surge mechanism is involved in sheep-to-sheep interaction for oestrous synchronisation. For that purpose, anoestrous ewes were inserted with intravaginal progestagen sponges for 13 days to induce ovulation. Upon sponge withdrawal, they were introduced either to 4 rams (n = 6, ram group), or to 4 ewes which were in follicular period (n = 6, follicular group), or 4 ewes which were in the luteal period (n = 6, luteal group) or else they were kept alone (n = 6, control group). The ewes were weighed and their body conditions were scored prior to the experiment. There were no significant differences in the body weights and body condition scores of the 4 groups. Blood samples were collected at 2 h intervals from sponge withdrawal (0 h) until the 96th h, and twice daily thereafter for 10 days. LH analyses were carried out on blood samples. According to data from the analyses, no LH surge was observed in the follicular and luteal groups within the 96 h following sponge withdrawal. The periods for observation of an LH surge were 162.7 ± 46.2, 224.0 ± 21.5, 58.7 ± 4.6 and 69.7 ± 6.7 h for the luteal, follicular, ram and control groups, respectively (P &amp;lt; 0.001). Although no significant difference was observed between the ram and control groups, the LH surge in these groups occurred significantly earlier than those of the luteal (P &amp;lt; 0.05 and P = 0.075, respectively) and follicular (P &amp;lt; 0.001 for both groups) groups. In conclusion, it appears that female sheep delay the LH surges compared to the ram-introduced or control groups and that female-to-female interaction seems to suppress preovulatory LH surge generation centres.
Morpheus Planetary Lander Liquid Propellant Fluid Slosh Modeling and Simulation Methods

Field: Engineering (Physical Sciences)

NASA and U.S. companies are taking first steps to design and build an autonomous vehicle, which will be able to explore the moon, asteroids and other planets. The NASA Morpheus Project is one of such efforts to develop and test autonomous lander technologies for future space exploration. The Morpheus lander is a terrestrial test vehicle, capable of vertical take off and landing using a gimbal controlled 4200 pounds thrust engine. The Morpheus lander serves as a test bed for liquid oxygen and liquid methane engine and autonomous landing and hazard avoidance technologies. Since the autonomous landing and hazard avoidance system requires a lander vehicle capable of reacting to its guidance and control, the lander vehicle flight control system has to be robust to the dynamics of six dimensional maneuvers and the changes in the physical properties due to propellants depletion and slosh. This paper focuses specifically on modelling the propellant slosh in the fuel tanks to help assess their effects on flight dynamics. In order to achieve this objective, research studies are being conducted to discover the most suitable and efficient methods of modeling and simulation for this vehicle. Two fundamental methods are presented. The first of which is to use solid modeling in three dimensions and transform those models for analysis of rigid and flexible bodies. A combination of SOLIDWORKS and the SIMWISE 4D is used. The second method is to model the vehicle and the fuel inside using Bond Graph technology. Such method allows for computer aided modeling techniques, which derive automatically the differential equations of the system and obtain the equations in symbolic form. The CAMPG (Computer Aided Modeling Program with Graphical Interface) is used for this purpose. CAMPG-MATLAB package is an integrated software package. Such symbolic representation is computed in a simulation and analysis software such as MATLAB. Modeling the fuel system as a pendulum of variable mass, in two and three dimensional models have been developed and analyzed.
ClickDiff: Click to Induce Semantic Contact Map for Controllable Grasp Generation with Diffusion Models

Field: Computer Science (Physical Sciences)

Grasp generation aims to create complex hand-object interactions with a\nspecified object. While traditional approaches for hand generation have\nprimarily focused on visibility and diversity under scene constraints, they\ntend to overlook the fine-grained hand-object interactions such as contacts,\nresulting in inaccurate and undesired grasps. To address these challenges, we\npropose a controllable grasp generation task and introduce ClickDiff, a\ncontrollable conditional generation model that leverages a fine-grained\nSemantic Contact Map (SCM). Particularly when synthesizing interactive grasps,\nthe method enables the precise control of grasp synthesis through either\nuser-specified or algorithmically predicted Semantic Contact Map. Specifically,\nto optimally utilize contact supervision constraints and to accurately model\nthe complex physical structure of hands, we propose a Dual Generation\nFramework. Within this framework, the Semantic Conditional Module generates\nreasonable contact maps based on fine-grained contact information, while the\nContact Conditional Module utilizes contact maps alongside object point clouds\nto generate realistic grasps. We evaluate the evaluation criteria applicable to\ncontrollable grasp generation. Both unimanual and bimanual generation\nexperiments on GRAB and ARCTIC datasets verify the validity of our proposed\nmethod, demonstrating the efficacy and robustness of ClickDiff, even with\npreviously unseen objects. Our code is available at\nhttps://github.com/adventurer-w/ClickDiff.\n
Bilateral comparison ofin situneurolipofuscin accumulation inCallinectes sapiduscaught in the wild

Field: Agricultural and Biological Sciences (Life Sciences)

Age determination using quantification of in situ neurolipofuscin has been an useful and reliable tool to understand population dynamics of crustaceans. In the present investigation, in situ neurolipofuscin was quantified in the medulla terminalis of eyestalks (cluster A cell mass, MT-A), and in the olfactory lobe cell mass 10 (OLCM-10) of the supra-oesophageal ganglion of unknown age blue crabs (Callinectes sapidus) caught in the wild. No significant difference in neurolipofuscin quantity was found between right and left MT-A and between right and left OLCM-10. Comparison between MT-A and OLCM-10 resulted in a weaker correlation. Average neurolipofuscin was 0.353±0.038% vol. and 0.896±0.105% vol. in MT-A and OLCM-10, respectively. Size explained 23% of the variation of neurolipofuscin loading in OLCM-10. No significant relationship was found between size and MT-A neurolipofuscin content. It can be concluded that both structures are suitable for the quantification of neurolipofuscin, and they have the potential for age determination for C. sapidus .
PROPERTIES OF CHARCOAL PRODUCED FROM REACTION WOOD IN TREES INCLINED DUE TO WIND1

Field: Agricultural and Biological Sciences (Life Sciences)

ABSTRACT Inclined trees produce reaction wood, whose properties are distinct from normal wood. This situation can affect the production of charcoal. This study was conducted to evaluate the quality of charcoal derived from reaction wood in trees of a commercial plantation inclined due to the action of wind. We used six year old wood from a Eucalyptus grandis xEucalyptus urophylla hybrid from plantations located in Minas Gerais. The physical and chemical properties of the wood were determined as well as the gravimetric yield and charcoal properties. According to the results, there were significant differences between the properties of the reaction and normal wood, with the reaction wood having lower levels of lignin and extractives, greater holocellulose content and low specific gravity. However, these characteristics of reaction wood did not significantly affect the properties of its charcoal.
