Performance and outcome of ressucitative thoracotomies in a southern Brazil trauma center: a 7-year retrospective analysis

ABSTRACT Objective: the study aims to analyze the performance and outcome of resuscitation thoracotomy (TR) performed in patients victims of penetrating and blunt trauma in a trauma center in southern Brazil during a 7 years period. Methods: retrospective study based on the analysis of medical records of patients undergoing TR, from 2014 to 2020, in the emergency service of the Hospital do Trabalhador, Curitiba - Paraná, Brazil. Results: a total of 46 TR were performed during the study period, of which 89.1% were male. The mean age of patients undergoing TR was 34.1±12.94 years (range 16 and 69 years). Penetrating trauma corresponded to the majority of indications with 80.4%, of these 86.5% victims of gunshot wounds and 13.5% victims of knife wounds. On the other hand, only 19.6% undergoing TR were victims of blunt trauma. Regarding the outcome variables, 84.78% of the patients had declared deaths during the procedure, considered non-responders. 15.22% of patients survived after the procedure. 4.35% of patients undergoing TR were discharged from the hospital, 50% of which were victims of blunt trauma. Conclusion: the data obtained in our study are in accordance with the world literature, reinforcing the need for a continuous effort to perform TR, respecting its indications and limitations in patients victims of severe penetrating or blunt trauma.
A Fully Bayesian Sample Size Determination for Inference on the Difference of two Binomial Proportions

A fully Bayesian approach for sample size determination for a clinical trial is presented in which the final decision whether to use the new treatment is taken by potential users and their medical advisers on the basis of the strength of the evidence provided by the trial. Data are assumed to come from two independent binomial distributions and the parameter of interest is 2 1 p p p − = , where 1 p and 2 p are two independent proportions. The optimal size is obtained by maximizing the expected net benefit function, which is the expected benefit from subsequent use of the new treatment minus the cost of the trial.
Discourse Analysis: A Tool for Helping Educators to Teach Science

In diesem Beitrag beziehen wir uns auf Teile eines kollaborativen Handlungsforschungsprojekts mit drei naturwissenschaftlichen Grundschulklassen. Ziel des Projekts war es, die diskursiven Praktiken der Lehrer/innen in Richtung eines kollaborativen Lehr- und Lernstils zu verandern. Hierzu wurden ihnen Moglichkeiten eroffnet, die eigenen Diskurse in naturwissenschaftlichem Unterricht mittels dreidimensionaler Analysekontexte zu reflektieren: Sie befassten sich mit ihren jeweils explizit oder implizit kommunizierten Botschaften uber den Charakter von Naturwissenschaft (CvN), den Charakter des Lehrens (CvL) und den Charakter von Sprache (CvS). Ziel war die Untersuchung der Frage, ob es im Rahmen eines Handlungsforschungsprogramms, das Lehrer/innen in die Analyse der eigenen Praktiken involviert, moglich ist, Transformationsprozesse der Kommunikation von CvN, CvL und CvS in einer eher an Zusammenarbeit mit den Schuler/innen interessierten Richtung zu initiieren? Die Ergebnisse legen nahe, dass die sukzessive Transformation diskursiver Repertoires im naturwissenschaftlichen Grundschulunterricht gelungen ist. Methodisch versuchen wir zu zeigen, dass Diskursanalysen fur Forschungszwecke, aber auch als Trainingsverfahren oder reflexive Instrumente in Unterrichtszusammenhangen genutzt werden konnen.

Analysis of the factors influencing parents’ support for child safety seat legislation in Nanjing

Abstract Objective Although the use of child safety seats can effectively ensure the safety of children in cars, the utilization rate of such seats in China is still low (<5%, 2021). Therefore, it is urgent to promote the use of child safety seats. The goal of this study was to examine the factors affecting parents' support for child safety seat legislation. Methods Data were collected via 1200 questionnaires distributed in several community hospitals in Nanjing. We used the data to do a multivariate logistic regression analysis to find the influencing factors of parental support for child safety seat legislation. Results On the whole, the respondents had low support for legislation mandating the installation of child safety seats. Although only 5.83% of the respondents expressed opposition to the relevant legislation, more than 40% expressed a neutral attitude rather than a supportive attitude. Multinomial logistic regression analyses revealed that gender, monthly household income, educational level, number of children in the family, comprehension of child safety seat-related publicity information, and cognition of children’s riding safety significantly affected parents' support for child safety seat legislation. In addition to gender and cognition of children's riding safety, other influential factors had significant positive impacts on legislative support for compulsory installation of child safety seats. Conclusion These results have implications for making more effective recommendations to advance child safety seat legislation and keep child passengers safe.
Systematic Review and Meta-Analysis of 16 Randomized Controlled Trials of Clinical Outcomes of Low-Intensity Extracorporeal Shock Wave Therapy in Treating Erectile Dysfunction

We conducted a meta-analysis to evaluate the efficacy of low-intensity extracorporeal shock wave therapy (LI-ESWT) in the treatment of erectile dysfunction (ED). From July 2011 to June 2021, we finally selected 16 randomized controlled trials (RCTs) including 1,064 participants to evaluate the efficacy of LI-ESWT in the treatment of ED from PubMed, EMBASE, and Cochrane databases. The data are analyzed by Review Manager Version 5.4. Fifteen articles mentioned International Index of Erectile Function (IIEF), in the follow-up of 1 month (mean difference [MD] = 3.18, 95% confidence interval [CI] = [1.38, 4.98], p = .0005), 3 months (MD = 3.01, 95% CI = [2.04, 3.98], p < .00001), and 6 months (MD = 3.20, 95% CI = [2.49, 3.92], p < .00001). After treatment, the improvement of IIEF in the LI-ESWT group was better than that in the control group. Besides, eight of the 16 trials provided data on the proportion of patients with baseline Erectile Hardness Score (EHS) ≤ 2 improved to EHS ≥ 3. The LI-ESWT group was also significantly better than the placebo group (odds ratio [OR] = 5.07, 95% CI = [1.78, 14.44], p = .002). The positive response rate of Questions 2 and 3 of the Sexual Encounter Profile (SEP) was not statistically significant (SEP2: OR = 1.27, 95% CI = [0.70, 2.30], p = .43; SEP3: OR = 4.24, 95% CI = [0.67, 26.83], p = .13). The results of this meta-analysis suggest that treatment plans with an energy density of 0.09 mJ/mm2 and pulses number of 1,500 to 2,000 are more beneficial to IIEF in ED patients. In addition, IIEF improvement was more pronounced in patients with moderate ED after extracorporeal shockwave therapy.
D ec 2 01 7 Ultralow and Anisotropic Thermal Conductivity in Semiconductor As 2 Se

An ultralow lattice thermal conductivity of 0.14 W· m· K along the ~b axis of As2Se3 single crystals was obtained at 300 K by first-principles calculations involving the density functional theory and the resolution of the Boltzmann transport equation. This ultralow lattice thermal conductivity arises from the combination of two mechanisms: 1) a cascade-like fall of the low-lying optical modes, which results in avoided crossings of these with the acoustic modes, low sound velocities and increased scattering rates of the acoustic phonons; and 2) the repulsion between the lonepair electrons of the As cations and the valence p orbitals of the Se anions, which leads to an increase in the anharmonicity of the bonds. The physical origins of these mechanisms lie on the nature of the chemical bonding in the material and its strong anisotropy. These results, whose validity has been addressed by comparison with SnSe, for which excellent agreement between the theoretical predictions and the experiments is achieved, point out that As2Se3 could exhibit improved thermoelectric properties.
Prognostic significance of tumor budding thresholds in oral tongue squamous cell carcinoma.

Oral tongue squamous cell carcinoma (OTSCC) represents the most common malignancy of the oral cavity. Tumor budding (TB) is a reliable prognostic factor in OTSCC; however, a standardized scoring system is not still validated. The study aims to evaluate the prognostic role of TB in 211 OTSCC patients treated between 1997-2018. TB was evaluated on haematoxylin and eosin-stained sections in the hotspot area of the infiltrative front (×200-magnification). It was scored using a two-tier, a three-tier system, and according to BD-model and revised-Grading system. Univariate and multivariate Cox regression analyses of disease-specific survival (DSS) and disease-free survival (DFS) were performed. A p-values<0.05 was considered as statistically significant. The two-tier and three-tier system resulted an independent prognostic factor of DSS. High-risk patients had a 2.21 and 3.08 times-increased probability of poor DSS compared to low-risk group. It is significantly increased even for intermediate-risk group. No significant differences emerged classifying patients according to BD-model and revised-Grading. These data confirm the prognostic value of TB in predicting DSS in OTSCC. Classifying patients in two groups using the 5-buds cut-off significantly discriminates their outcomes. Since the established role of DOI and the poor prognostic value of grading, TB could be considered an independent prognostic marker.
Address inputting while driving: a comparison of four alternative text input methods on in-vehicle navigation displays usability and driver distraction

Abstract Objective Efficient and safe address entry is crucial to in-vehicle navigation systems. Although various text input methods (TIMs) are commercially available, to date, the details of the driver’s interactions with these TIMs in the vehicle are poorly understood. Therefore, the effect of four alternative TIMs conditions on in-vehicle navigation displays usability and driver distraction were directly compared. For reference, the baseline driving task (distraction-free) was also investigated. Methods A city expressway simulator experiment including 25 young drivers was launched. Under each condition, the driving task was lane-keeping with speed ranging between 40 and 60 km/h, and the navigation task was to enter a 14-characters Chinese address name. In the meantime, usability (text entry time, number of errors, and preference) and driver distraction (NASA-TLX, average speed, the standard deviation of lane position, total glance duration, number of glances, average glance duration, and number of glances exceeding 1.6 s) metrics were measured as dependent variables. A sequence of one-way repeated measure analyses of variance (ANOVA) was performed to examine which type of TIMs can maximize in-vehicle navigation displays usability and minimize driver distraction. Results Generally, lateral driving performance deteriorated with the addition of the address inputting task, and the four alternative TIMs might fall into three levels: Speech is optimal, Qwerty followed, Shape-writing and Handwriting ranked last. Specifically, word-based speech remains performed best on all observed metrics for Chinese address names. There was an insignificant difference in text entry time and total glance duration among Qwerty, Shape-writing, and Handwriting. However, Shape-writing and Handwriting are not suitable for young drivers since the nature of uninterruptible causes excessive errors, more considerable lane position variation, longer average glance duration, and more glances exceeding 1.6 s. Conclusions This study provides valuable insights into young drivers’ interactions with four alternative TIMs. Importantly, it is beneficial to the automotive user interfaces design of in-vehicle navigation displays and other sub-functions of in-vehicle information systems (IVISs), such as music playback and text messaging, which positively mitigate driver distraction and prevent traffic injuries.
IT'S IN THE GENES: EXPLORING RELATIONSHIPS BETWEEN CRITICAL THINKING AND PROBLEM SOLVING IN UNDERGRADUATE AGRISCIENCE STUDENTS' SOLUTIONS TO PROBLEMS IN MENDELIAN GENETICS

This study was conducted to examine the statistical relationship between problem solving and critical thinking to guide future teaching and research for agricultural educators using the problem-solving approach. Students enrolled in an undergraduate genetics course in the College of Agricultural and Life Sciences at the University of Florida were prompted to use their criticalthinking skills while answering a problem in the context of biotechnology. Students’ criticalthinking skills were assessed through content analysis of a think-aloud protocol. Other cognitive factors assessed included problem-solving style, problem-solving level, and critical-thinking disposition. A path analysis was used to examine how these trait-based variables and use of critical-thinking skills contribute to solving a problem. Of these cognitive factors, only problemsolving level, critical-thinking disposition, and use of critical-thinking skills were included in the revised model. The authors argue that although correlations were significant, they were low and indicated that critical thinking and problem-solving may be more independent than previously thought. Limitations of this study require more research to better understand how these cognitive factors are employed by the learner to solve problems.
Investigation into the ophthalmic artery and its branches by superselective angiography

Background The vascular anatomy of orbit is highly complex, and the main blood supply to the orbit is via the ophthalmic artery, which is a branch of the internal carotid artery. The purpose of this study was to determine the morphometry of the ophthalmic artery and its branches by superselective angiography in a large series of pediatric patients. Methods We evaluated 134 angiographies performed on children with intraocular retinoblastoma undergoing intra-arterial chemotherapy. The origin, diameter, and angiographic visibility percentages of the ophthalmic artery and its branches were examined according to age group and sex. Results The ophthalmic artery originated 97.8% from the internal carotid artery and 2.2% from the middle meningeal artery. The mean diameter of ophthalmic artery was measured 0.76 ± 0.14 mm in girls, 0.80 ± 0.15 mm in boys and 0.79 ± 0.15 mm in general. The posterior ciliary, lacrimal, inferior muscular, and anterior ethmoidal arteries had a higher angiographic visibility percentages (> 85%) than the other OA branches. Only the diameter of the dorsal nasal artery showed a significant correlation with age. The supratrochlear and posterior ciliary arteries showed statistically significant relationship with sex. Conclusions Present study will make a substantial contribution to the pediatric literature about the ophthalmic artery and its branches. A better understanding of ophthalmic artery morphology can help surgeons and neurointerventional radiologists to avoid possible severe complications during embolization, intra-arterial chemotherapy, cosmetic procedures, endonasal and orbital surgeries.
Changes in cognitive performance after cochlear implantation in adults and older adults: a systematic review and meta-analysis

Abstract Objectives To conduct critical assessment of the literature on the effects of cochlear implantation on adults’ cognitive abilities. Design PubMed, Scopus, Lilacs, Web of Science, Livivo, Cochrane, Embase, PsycInfo, and grey literature were searched. Eligibility criteria: age 18 or over with severe-to-profound bilateral hearing loss, cochlear implantation, cognitive test before and after implantation. Risk of bias was assessed using ROB, ROBINS-I and MASTARI tools. Meta-analysis was performed. Study sample Out of 1830 studies, 16 met the inclusion criteria. Results On AlaCog test, significant improvement was found after implantation [MD = −46.64; CI95% = −69.96 to −23.33; I 2 = 71%]. No significant differences were found on the Flanker, Recall, Trail A and n-back tests (p > 0.05). For MMSE, no significance was found [MD 0.63; CI 95% = −2.19 to 3.45; I 2 = 88%]. On TMT, an overall significant effect with a 9-second decrease in processing speed post-implantation [MD = −9.43; CI95% = −15.42 to −3.44; I 2 = 0%]. Conclusion Cognitive improvements after cochlear implantation may depend on time and the cognitive task evaluated. Well-designed studies with longer follow-up are necessary to examine whether cochlear implantation has a positive influence on cognitive abilities. Development of cognitive assessment tools to hearing-impaired individuals is needed.
Onboard Sensors-Based Self-Localization for Autonomous Vehicle With Hierarchical Map

Localization is a fundamental and crucial module for autonomous vehicles. Most of the existing localization methodologies, such as signal-dependent methods (RTK-GPS and Bluetooth), simultaneous localization and mapping (SLAM), and map-based methods, have been utilized in outdoor autonomous driving vehicles and indoor robot positioning. However, they suffer from severe limitations, such as signal-blocked scenes of GPS, computing resource occupation explosion in large-scale scenarios, intolerable time delay, and registration divergence of SLAM/map-based methods. In this article, a self-localization framework, without relying on GPS or any other wireless signals, is proposed. We demonstrate that the proposed homogeneous normal distribution transform algorithm and two-way information interaction mechanism could achieve centimeter-level localization accuracy, which reaches the requirement of autonomous vehicle localization for instantaneity and robustness. In addition, benefitting from hardware and software co-design, the proposed localization approach is extremely light-weighted enough to be operated on an embedded computing system, which is different from other LiDAR localization methods relying on high-performance CPU/GPU. Experiments on a public dataset (Baidu Apollo SouthBay dataset) and real-world verified the effectiveness and advantages of our approach compared with other similar algorithms.
Relationship of Temperament Differences with Diagnosis, Severity and Accompanying Psychiatric Symptoms in Autism Spectrum Disorder

Introduction: Temperament differences were shown in children with autism spectrum disorder (ASD); however, associations of temperament with ASD severity and accompanying psychiatric symptoms have yet to be studied. Methods: We evaluated 58 ASD-diagnosed children’s temperaments through disorder severity and psychiatric symptoms and compared them with 58 typically developed children. We utilized the Children’s Behavior Questionnaire-Short Form, The Strengths and Difficulties Questionnaire (SDQ). The Childhood Autism Rating Scale (CARS) was used to evaluate psychiatric symptoms and ASD severity levels of children. Results: Negative affect, effortful control, and perceptual sensitivity were found lower in ASD-diagnosed children and decreased with ASD severity. Effortful control was also found negatively correlated with scores of behavioral problems, hyperactivity, and total difficulties. Besides, anger/ frustration was found predictive for conduct and peer problems, and total difficulty scores. Conclusion: Further studies are needed to verify and expand these pioneer findings. ABSTRACT
A review of 91 canine and feline red‐bellied black snake (Pseudechis porphyriacus) envenomation cases and lessons for improved management

Introduction Most cases of red‐bellied black snake (RBBS) envenomation in dogs respond favourably to treatment comprising of tiger‐brown snake antivenom (TBAV), intravenous fluid therapy, analgesia and, if indicated, mechanical ventilation and/or blood transfusion. However, there remains a subset of patients who develop fatal complications despite intensive treatment and risk factors for these occurring remain unknown. Here we present a retrospective cross‐sectional survey of 91 canine and feline RBBS envenomation cases. Methods Cases seen between June 2010 and June 2020 were retrieved from the databases of seven practices in South East and coastal Queensland. From the canine case population, logistic regression analysis was performed to assess the impact of potential risk factors at presentation on the likelihood of death. A final multivariable model was developed using a manual backwards elimination approach based on overall likelihood ratio tests and Wald chi‐square P‐values for each variable. Where model convergence failed due to quasi‐complete separation, Firth's penalised maximum likelihood method was implemented. Such separation may occur when an outcome is completely predicted by an explanatory variable in one group. Results Of the 88 canine cases, 7 died (8.0%), all after prognosis‐based euthanasia. Of the three feline cases, one died after unsuccessful resuscitation following cardiopulmonary arrest. Compared to survivors, dogs that died were older, exhibited pigmenturia, received antivenom later and had a higher total plasma protein (TPP), activated clotting time (ACT) and lower packed cell volume (PCV) at presentation.
COOPER PAIRING IN SPIN-POLARIZED FERMI SYSTEMS

I discuss the phenomenon of Cooper pairing in strongly spin-polarized Fermi systems, such as 3He+ and D+, with particular attention to the questions (1) what are the conditions for Cooper pairing to occur, and at what temperatures is this likely to happen for the systems of practical interest ? (2) what is the relationship between Cooper pairs and diatomic molecules ? (3) what are the qualitatively new phenomena we expect in a Cooper-paired system, and what new physics is likely to emerge if the phenomena occurs in spin-polarized systems ?
Becoming a ‘tweep’. Networks of affiliation and relational pressures on Twitter

The paper presents findings from a qualitative study about sociality and the self in network-based social media, as examined through a case study of ordinary Danes’ uses of Twitter. Drawing on Georg Simmel’s work on networks of affiliation, the paper investigates the collaborative process through which individual users’ expressions of self are negotiated in specific networks of affiliation on Twitter, and demonstrates the significant role played by these networks in this process. The communicative affordances of Twitter, and the interactional and relational dynamics create a pressure towards the expression of a particular, restricted version of the individual user’s self. By enhancing certain aspects of the self and not other aspects, the user can connect to relevant others and become accepted and recognised in a network of affiliation. That is, the use can become ‘one of the tweeps’.
