The pO2 of Samples Drawn from the Shiley S-100A Arterial Reservoir Is Not an Accurate Indicator of Arterial Line pO2
Authors: Wagoner Philip A. , Pauley David W. , Brown Darrell M. , Plevich Joel P. 
Published: September 2023

While conducting clinical bypass with the Shiley S-100A bubble oxygenator, an observation was made that arterial pO2 values reported by the laboratory were routinely inconsistent with inline arterial blood oxygen saturation measurements. It was also noted that the blood in the arterial reservoir in the vicinity of the arterial sampling port was often darker in color than the blood in the arterial line.
Sixty-four simultaneously drawn pairs of arterial blood gas samples were drawn from the arterial reservoir sampling port and from the purge line of the arterial line filter (ALF). In all instances, the pO2 of the sample drawn from the arterial line filter exceeded the pO2 of the corresponding sample drawn from the arterial reservoir. The percentage difference between the pO2 of samples drawn from the ALF and from the arterial reservoir correlated strongly (p < .01) with the arterial blood temperature and moderately (p < 0.2) with the reservoir level. No significant differences were found between the pCO2, pH and base excess of the ALF and the arterial reservoir.
The authors postulate that the discrepancy in pO2 between the arterial reservoir sampling port and the ALF is a result of rapid channelling of partially oxygenated blood through the defoamer into the vicinity of the arterial sampling port. The rapidly channelled blood is, therefore, deprived of the additional oxygenation that occurs in the defoamers of bubble oxygenators.
It is recommended that Shiley reposition the S-100A’s arterial sampling port closer to, the arterial reservoir outlet port and that a unidirectional valve be inserted to prevent inadvertent introduction of air to the arterial reservoir. Until this design modification is carried out, the authors recommend that clinical users of the S-100A draw arterial blood gas samples directly from the arterial line or from the ALF purge line.
A Reliable Method for Determination of Initial Sweep Gas Flow Rates Using the CML Oxygenator
Authors: Myers Gerard J. 
Published: September 2023

(J. Extra-Corpor. Technol. 18[4] p.221–224 Winter 1986) The Cobe Membrane Lung Oxygenator is a Z folded flat plate membrane made of polypropylene material, with an effective surface area of 2.5m2. Since its introduction to the market in 1982, it has provided perfusionists with all the benefits of the membrane technology, while utilizing an ease of operation that is equal to the bubble oxygenator. Cobe’s initial recommendation for use was to maintain a constant sweep gas flow rate of 10 liters/minute and control the pCO2 by adding extraneous carbon dioxide to this ventilating gas. However, the use of Alpha Stat Control (nontemperature correction) for acid base balance requires the elimination of all extraneous carbon dioxide during bypass, and thereby has required perfusionists to rely on their own experience with this membrane, or follow Cobe’s second recommendation of establishing an initial sweep gas flow rate of 1:1 (gas:blood).
Presented here is a method of determining the initial sweep gas flow rate while using Alpha Stat Control. This method appears useful during the initiation of bypass and the use of moderate hypothermic temperature. A well-known parameter in respiratory medicine, the V/Q ratio, is used in the determination and must be established prior to bypass.
The results of this paper indicate that use of the V/Q ratio in establishing a desired PaCO2 for the first 1 0 minutes of bypass is more reliable and consistent than the use of the 1:1 gas to blood flow ratio. However, the method has proved useful only for the initial blood gas sampling, after which sweep gas flows must be reduced to a V/Q of at least 1.0 for the remainder of the case. Use of the V/Q ratio appears to allow the perfusionist to predict the initial PaCO2 within an accuracy of ± 4 mmHg.
The Development of a Perfusion Educational Program
Authors: Paules Brian R. 
Published: September 2023

(J. fxtra-Corpor. Technol. 19[2] p. 216–220 Summer 1987). The development of a School of Perfusion Technology starts with a purpose statement that defines the need for such a program and the role of the school within the professional community.
After defining the purpose for such an educational program, a task analysis provides the program description of a perfusionist, which later is used to develop the curriculum. A goal analysis details what the student and program will achieve at completion. A statement of the professional and educational philosophy along with the program objective complete the basic foundation.
Level of sponsorship of the program determines the duration of education, physical resources, budgetary support, clinical availability and instructional faculty. A target population study forms the basis to define the applicant traits desirable for the program. All of the above data are combined to generate an application process and to begin to create the curriculum.
Specific subject matter is listed to include all pertinent and ancillary topics along with the approximate time required to cover each topic. Classes are developed from the topic list, with material coordinated to provide an overlap of knowledge between classes. Statement of course goals and objectives defines the learning expectation while the examination evaluates student knowledge.
Clinical rotations provide the opportunity for practical application of the scientific principles learned in the didactic portion of the education. Pre and post clinical evaluations are essential toward determining student’s strengths and weaknesses, in order to validate his or her knowledge in the clinical practice. This form of education mandates a single instructor per student and continual vigilance.
An outcome analysis is generated after graduation with employer feedback and peer review of the graduate perfusionist. From this analysis the program goals and objectives are tested, and program re-evaluation begins.
Hematological Effects during Clinical Extracorporeal Circulation: A 200 Case Study of the Shiley M-2000 Membrane System
Authors: John E. Briddon D. 
Published: September 2023

(J. Extra-Corpor. Technol. 19[3] p. 312-315 Fall 1987, 6 ref.) The hematological effects of the Shiley M-2000 Membrane Oxygenator System were evaluated during and after cardiopulmonary bypass (CPB) in 200 patients who required coronary artery revascularization. A strict protocol for perfusion management and blood sampling was established and adhered to. Bypass times varied from 11/2 hours to 81\2 hours (X = 2 hrs 48 mins). Hemolysis was observed to be minimal, blood cells were well preserved, and, in particular, platelet counts and platelet function remained stable, even in bypass times in excess of 8 hours.
It was noted that when CPB was discontinued, and protamine sulphate infusion commenced, platelet function decreased slightly, although the platelet counts remained unchanged. Average postoperative blood loss was 390 mls (21 0 mls-1 ,400 mls range), statistically significantly lower than the average blood loss in a previous study at our center, which utilized the same protocol but an alternative membrane (Cobe CML).
In summary the Shiley M-2000 Membrane is a safe and extremely hemocompatible system for use in short- to medium-term perfusions.

Transient Hypoglycemia and Biochemical Differences in Infants Less Than 1,250 G at Birth Fed Human Milk with Human Milk–Derived Fortifier versus Cow Milk–Derived Fortifier
Authors: Chang Millie R. , Tetarbe Manas , Barton Lorayne , Ramanathan Rangasamy , Cayabyab Rowena 
Published: September 2023

Objective Fortification of human milk (HM) with either human milk-derived fortifier (HMDF) or cow milk-derived fortifier (CMDF) is important in preterm infants. The objective is to compare the incidence of hypoglycemia, and biochemical values in infants less than 1,250 g at birth fed HMDF versus CMDF.
Study Design It is a retrospective cohort study on infants less than 1,250 g at birth who were fed with HMDF or CMDF. Hypoglycemia was defined as blood glucose (BG) level equal to or less than 60 mg/dL within 72 hours of full enteral feeds when off total parenteral nutrition and intravenous fluids.
Results Ninety infants were enrolled (HMDF = 61, CMDF = 29). HMDF group had a higher rate of hypoglycemia (46 vs. 24%; p = 0.048) after achievement of full enteral feeding. The median minimum BG was lower (61 vs. 71; p ≤ 0.01), while blood urea nitrogen (12 vs. 6; p ≤ 0.01) and albumin (3.1 vs. 2.7; p ≤ 0.01) were higher in HMDF group compared with CMDF.
Conclusion At full enteral feedings in infants less than 1,250 g at birth, an HMDF diet may predispose to hypoglycemia needing intervention. Close monitoring of BG levels once off parenteral nutrition is recommended.
Key Points
Phenotypes of Disseminated Intravascular Coagulation
Authors: Wada Takeshi , Gando Satoshi 
Published: September 2023

AbstractTwo phenotypes of disseminated intravascular coagulation (DIC) are systematically reviewed. DIC is classified into thrombotic and fibrinolytic phenotypes characterized by thrombosis and hemorrhage, respectively. Major pathology of DIC with thrombotic phenotype is the activation of coagulation, insufficient anticoagulation with endothelial injury, and plasminogen activator inhibitor-1-mediated inhibition of fibrinolysis, leading to microvascular fibrin thrombosis and organ dysfunction. DIC with fibrinolytic phenotype is defined as massive thrombin generation commonly observed in any type of DIC, combined with systemic pathologic hyperfibrinogenolysis caused by underlying disorder that results in severe bleeding due to excessive plasmin formation. Three major pathomechanisms of systemic hyperfibrinogenolysis have been considered: (1) acceleration of tissue-type plasminogen activator (t-PA) release from hypoxic endothelial cells and t-PA-rich storage pools, (2) enhancement of the conversion of plasminogen to plasmin due to specific proteins and receptors that are expressed on cancer cells and endothelial cells, and (3) alternative pathways of fibrinolysis. DIC with fibrinolytic phenotype can be diagnosed by DIC diagnosis followed by the recognition of systemic pathologic hyperfibrin(ogen)olysis. Low fibrinogen levels, high fibrinogen and fibrin degradation products (FDPs), and the FDP/D-dimer ratio are important for the diagnosis of systemic pathologic hyperfibrin(ogen)olysis. Currently, evidence-based treatment strategies for DIC with fibrinolytic phenotypes are lacking. Tranexamic acid appears to be one of the few methods to be effective in the treatment of systemic pathologic hyperfibrin(ogen)olysis. International cooperation for the elucidation of pathomechanisms, establishment of diagnostic criteria, and treatment strategies for DIC with fibrinolytic phenotype are urgent issues in the field of thrombosis and hemostasis.
The Brain Balance® programme improves attention and classroom behaviour in students with attentional and developmental challenges in a school setting (El programa Brain Balance® mejora la atención y el comportamiento en el aula de estudiantes con dificultades de atención y de desarrollo en un entorno escolar)
Authors: Jackson Rebecca , Glanz Ryan M. 
Published: September 2023

The Brain Balance® (BB) programme has been examined in a centre-based setting, but not yet in a school setting. This pilot study assessed sensorimotor, behavioural and cognitive functioning of students aged 5–15 years with pre-existing developmental and academic challenges who attended three one-hour sessions/week of the BB programme on-site at school ( n = 15). Non-participating students served as controls (CTLs; n = 11). Before the programme, BB participants were more likely than CTLs to achieve low scores on at least two of six Cambridge Brain Sciences (CBS) cognitive tests. After the programme, the number of these participants with low scores decreased, compared with CTLs. Following participation, the BB group also demonstrated diminished primitive reflexes and improvement in scores on the Vanderbilt ADHD Diagnostic Teacher Rating Scale (VADTRS), and higher scores on sensorimotor tasks, compared with CTLs. Finally, BB participants tended to improve test accuracy and reaction times on six CBS cognitive tests (non-significant). These preliminary results show the potential efficacy of the BB programme in a school setting. Future studies will assess the programme in larger student populations.
An asymptotic framework for gravitational scattering
Authors: Compère Geoffrey , Gralla Samuel E , Wei Hongji 
Published: September 2023

AbstractAsymptotically flat spacetimes have been studied in five separate regions: future/past timelike infinityi±, future/past null infinity, and spatial infinityi0. We formulate assumptions and definitions such that the five infinities share a single Bondi–Metzner–Sachs (BMS) group of asymptotic symmetries and associated charges. We show how individual ingoing/outgoing massive bodies may be ascribed initial/final BMS charges and derive global conservation laws stating that the change in total charge is balanced by the corresponding radiative flux. This framework provides a foundation for the study of asymptotically flat spacetimes containing ingoing and outgoing massive bodies, i.e. for generalized gravitational scattering. Among the new implications are rigorous definitions for quantities like initial/final spin, scattering angle, and impact parameter in multi-body spacetimes, without the use of any preferred background structure.
Strong infiltrative HHC36 antimicrobial peptide/silver nanoparticles-loaded carboxymethyl chitosan/sodium alginate hydrogel for acne vulgaris therapy

Published: September 2023

Abstract
Acne is a common chronic skin inflammatory disease closely related to Cutibacterium acnes (C. acnes), which affects the life quality of patients worldwide, especially adolescents and young adults. However, the physical barrier of the skin makes drugs difficult to infiltrate effectively into infected site, causing acne hard to cure and easy to recur. Herein, we developed an antibacterial skin dressing with strong infiltration of antibacterial agents which can co-delivery small-molecular antimicrobial agents through stratum corneum deeply into dermis, achieving high antimicrobial efficacy. The antibacterial dressings were constructed with carboxymethyl chitosan/sodium alginate (CMCS/SA) hydrogel loading with HHC36 (an antimicrobial peptide) and silver nanoparticles (AgNPs) conjugates (Ag–H2/CMCS/SA hydrogel). The released Ag–H2 from Ag–H2/CMCS/SA hydrogel can early infiltrate into dermis, co-delivery HHC36 and AgNPs due to the infiltration and targeting of HHC36, presenting the superior antibacterial effect compared to HHC36 or AgNPs alone and killing 100% C. acnes and 100% Staphylococcus epidermidis (S. epidermidis) at a very low concentration of Ag–H2 (15 μg ml−1 A g with 7.1 μg ml−1 HHC36). Meanwhile, Ag–H2/CMCS/SA hydrogel was biocompatible due to the natural polysaccharides carboxymethyl chitosan and sodium alginate. The HaCaT cells spread well in Ag–H2/CMCS/SA hydrogel. These results indicate that the co-delivery small-molecular antimicrobial agents is a promising strategy and Ag–H2/CMCS/SA hydrogel has a great potential in the therapy of acne.

Abstract
In this paper, we compiled a sample of 410 Fermi-detected BL Lacs, including 42 TeV-detected BL Lacs (TBLs) and 368 non-TeV-detected BL Lacs (non-TBLs) with corresponding mid-infrared (mid-IR), TeV and Fermi γ-ray data, and calculated some important parameters including monochromatic luminosities (mid-IR, GeV and TeV bands) and mid-IR spectral indices. Based on those parameters, we discussed the relationship between the mid-IR and the TeV bands and that between the mid-IR and the GeV bands. Main conclusions are drawn as follows: (1) In the color–color and color–magnitude diagrams, our sample forms a WISE-Gamma Strip in the [3.4]–[4.6]–[12] μm color–color diagram, and TBLs occupy the brighter region than the non-TBLs for the similar color-index in the color-magnititue diagram; (2) The mid-IR luminosity of the TBLs is on average higher than that of non-TBLs, while the average mid-IR spectral index of TBLs is smaller than the non-TBLs, suggesting that TBLs are brighter and hold a more flat spectrum than do the non-TBLs in the mid-IR band. Besides, HBLs have a more flat mid-IR spectrum than LBLs and IBLs; (3) The mid-IR luminosity is positively correlated with the GeV luminosity and the intrinsic TeV luminosity. A positive correlation exists between the mid-IR spectral index and the observed TeV spectral index, which is consistent with the expectations of the synchrotron self-Compton mechanism. We suggest that the HBLs with extreme relativistic electrons might scatter the mid-IR photons up to the TeV band.
Gait recognition with covariate separation based on adversarial learning
Authors: Zhu Yongsheng , Hu Weijun , Zhou Hongming 
Published: September 2023

Abstract
In response to the poor recognition accuracy caused by viewpoint changes and wearing changes in gait recognition problems, a viewpoint classifier and a wearing classifier are proposed to be connected after the feature extractor. The parameters of the feature extractor are updated using the gradient reversal mechanism so that its function is opposite to that of the two classifiers, thereby separating the viewpoint information, wearing information at the feature extraction level, and reducing the impact of these two most common factors on gait recognition. Comparative experiments on the CASIA-B dataset show that under BG and CL conditions, our model has improved by an average of 2.1% and 1.9% in cross-viewpoint accuracy compared to the baseline model. Our model is more robust under complex walking conditions.
Barcode positioning method based on line detection under non-uniform illumination
Authors: Sang Mingxiu 
Published: September 2023

Abstract
The positioning problem of the barcode is easily affected by factors such as uneven illumination and complex background. Based on the EDLines line detection algorithm, a positioning algorithm that can deal with the barcode positioning problem under non-uniform lighting conditions is proposed. First, the EDLines algorithm is used to detect the straight-line segment of the image, and the midpoint coordinates of all line segments are extracted. Since the midpoint coordinates near the barcode are relatively densely distributed, the density-based HDBSCAN point clustering algorithm is used for all midpoint coordinates for density clustering. Then a filtering strategy based on the consistency of line segment direction is proposed to preliminarily filter the clustering results, and one or more point clustering results that may belong to the barcode area are obtained. Then the RANSAC algorithm is used to perform line fitting on the point clustering results. The accuracy of the straight-line fitting results is judged by direction consistency screening, and the intersection of the fitted straight line and the straight-line segment to which the centroid belongs is calculated for the results that meet the expectations, and the width of the barcode area is obtained. Finally, the straight-line segment obtained by screening is calculated. The average length and the height of the barcode area are got, to accurately locate the barcode position. Compared with the previous algorithms on the public barcode dataset and the self-made barcode dataset, the algorithm has good positioning accuracy and running speed.
A Re-detection Target Tracking Framework after Loss for Unmanned Aerial Vehicle
Authors: Chao Chuang , Wu Jun , Zhang Yuxin , Chen Honglin 
Published: September 2023

Abstract
Currently, the target tracking algorithm based on discriminative correlation filter (DCF) and deep learning (DL) plays an increasingly important role in UAV (unmanned aerial vehicle). However, existing algorithms have limitations such as limited search region, difficulty in re-capturing targets when tracking is lost, and high computational complexity, which makes them difficult to apply to the UAV platform. In this paper, a target re-detection tracking algorithm (RDT) after tracking loss is designed for mobile platforms. RDT uses DCF in simple scenes to track targets and establish a target model between different frames. To ensure the algorithm when tracking is lost due to occlusion or moving out of view, an efficient switching criterion is designed to indirectly invoke the detection algorithm to re-capture the target and guide online learning of DCF. And the experiment results on the OTB benchmark show that RDT can re-capture the target after tracking is lost, and the speed of operation on the CPU is 85fps.
Spatial-temporal regularized UAV correlation filter based on adaptive filter template
Authors: Chai Jinchuan , Ding Jialiang 
Published: September 2023

Abstract
Due to its quick computation, the correlation filter (CF) is frequently employed in object-tracking activities. The occlusion and deformation of the tracking object during the CF tracking process will pollute the filter, which will cause the filter’s performance to degrade. This is especially obvious in unmanned aerial vehicle (UAV) tracking and increased interfered sequences will further aggravate the problem. In response to this problem, we use ARCF as the baseline and add a spatial-temporal regularization term based on the adaptive template. We also introduce a historical filter template to generate a more global adaptive template. The experimental results illustrate that our tracker has the most sophisticated capabilities compared to the other 8 SOTA trackers on the DTB70 benchmark.

Exploring the distribution law of star position simulation error and establishing a corrected sub interval based on it, achieving sub pixel level star position simulation accuracy. The experimental results show that after using the method proposed in this article, the accuracy of star position simulation has been improved by 1.74 times.
