This study aims to elucidate the state of physicians’ theoretical knowledge in Ecuador based on Basic Life Support (BLS) and Advanced Life Support (ALS) guidelines.Patients and methods: A national cross-sectional online 35-questions survey was conducted between February and March 2023 using a self-administered, expert-validated questionnaire. Participants’ responses were obtained through official social media groups (WhatsApp and Facebook). The survey evaluated the theoretical knowledge of BLS and ALS, with scores based on the number of correct answers out of a maximum of 10.0 points. For descriptive analysis, frequencies, percentages, means, and standard deviations (SD) were used. The T-test and one-way ANOVA were utilized to analyze the associations between knowledge levels and demographic and academic training variables of Ecuadorian doctors. Values of p < 0.05 were considered statistically significant for all analyses.Results: The survey garnered responses from 385 physicians, with a majority being female (56.6%) and possessing less than 3 years of work experience (75.1%). Of these, 71.7% and 51.9% held BLS and ALS certifications, respectively. Knowledge scores for BLS (5.8/10 ± 1.6) surpassed those for ALS (4.7/10 ± 1.8) (p < 0.001). Physicians with less than 3 years of work experience exhibited higher knowledge scores in both BLS and ALS tests (p < 0.05).Conclusion: This study revealed a notable deficiency in the theoretical knowledge of BLS and ALS among surveyed Ecuadorian physicians. Factors such as prior certification and years of work experience appeared to influence knowledge levels. Continual training and updates in life support protocols at universities and healthcare institutions are key to enhancing physicians’ skills and patient outcomes.Keywords: cardiopulmonary resuscitation, knowledge, education, medical, physicians

Abstract

We systematically investigate the relationships between structural and electronic effects of finite size zigzag or armchair carbon nanotubes of various diameters and lengths, starting from a molecular template of varying shape and diameter, i.e. cyclic oligoacene or oligophenacene molecules, and disclosing how adding layers and/or end-caps (i.e. hemi-fullerenes) can modify their (poly)radicaloid nature. We mostly used tight-binding and finite-temperature density-based methods, the former providing a simple but intuitive picture about their electronic structure, and the latter dealing effectively with strong correlation effects by relying on a fractional occupation number weighted electron density (\rho FOD ), with additional RAS-SF calculations backing up the latter results. We also explore how minor structural modifications of nanotube end-caps might influence the results, showing that topology, together with the chemical nature of the systems, is pivotal for the understanding of the electronic properties of these and other related systems.

Abstract

Mapping of the forces on biomolecules in cell membranes has spurred the development of effective labels, e.g. organic fluorophores and nanoparticles, to track trajectories of single biomolecules. Standard methods use particular statistics, namely the mean square displacement, to analyze the underlying dynamics. Here, we introduce general inference methods to fully exploit information in the experimental trajectories, providing sharp estimates of the forces and the diffusion coefficients in membrane microdomains. Rapid and reliable convergence of the inference scheme is demonstrated on trajectories generated numerically. The method is then applied to infer forces and potentials acting on the receptor of the $\epsilon$-toxin labeled by lanthanide-ion nanoparticles. Our scheme is applicable to any labeled biomolecule and results show show its general relevance for membrane compartmentation., Comment: 6 pages, 4 figures

Abstract

A summary of the technical advances that are incorporated in the fourth major release of the Q-Chem quantum chemistry program is provided, covering approximately the last seven years. These include developments in density functional theory methods and algorithms, nuclear magnetic resonance (NMR) property evaluation, coupled cluster and perturbation theories, methods for electronically excited and open-shell species, tools for treating extended environments, algorithms for walking on potential surfaces, analysis tools, energy and electron transfer modelling, parallel computing capabilities, and graphical user interfaces. In addition, a selection of example case studies that illustrate these capabilities is given. These include extensive benchmarks of the comparative accuracy of modern density functionals for bonded and non-bonded interactions, tests of attenuated second order Møller-Plesset (MP2) methods for intermolecular interactions, a variety of parallel performance benchmarks, and tests of the accuracy of implicit solvation models. Some specific chemical examples include calculations on the strongly correlated Cr2 dimer, exploring zeolite-catalysed ethane dehydrogenation, energy decomposition analysis of a charged ter-molecular complex arising from glycerol photoionisation, and natural transition orbitals for a Frenkel exciton state in a nine-unit model of a self-assembling nanotube.

Abstract

Pattern recognition techniques have been employed in a myriad of industrial, medical, commercial and academic applications. To tackle such a diversity of data, many techniques have been devised. However, despite the long tradition of pattern recognition research, there is no technique that yields the best classification in all scenarios. Therefore, the consideration of as many as possible techniques presents itself as an fundamental practice in applications aiming at high accuracy. Typical works comparing methods either emphasize the performance of a given algorithm in validation tests or systematically compare various algorithms, assuming that the practical use of these methods is done by experts. In many occasions, however, researchers have to deal with their practical classification tasks without an in-depth knowledge about the underlying mechanisms behind parameters. Actually, the adequate choice of classifiers and parameters alike in such practical circumstances constitutes a long-standing problem and is the subject of the current paper. We carried out a study on the performance of nine well-known classifiers implemented by the Weka framework and compared the dependence of the accuracy with their configuration parameter configurations. The analysis of performance with default parameters revealed that the k-nearest neighbors method exceeds by a large margin the other methods when high dimensional datasets are considered. When other configuration of parameters were allowed, we found that it is possible to improve the quality of SVM in more than 20% even if parameters are set randomly. Taken together, the investigation conducted in this paper suggests that, apart from the SVM implementation, Weka's default configuration of parameters provides an performance close the one achieved with the optimal configuration.

28. On minimum time vehicle manoeuvring : the theoretical optimal lap

Abstract

This work is a research on the minimum time vehicle manoeuvring problem, with a particular application to finding the minimum lap time for a Formula One racing car. The proposed method allows to solve the general problem of evaluating the vehicle lateral and longitudinal controls which yield the minimum time required to traverse a lap of a circuit. The minimum time vehicle manoeuvring problem is formulated as one of Optimal Control and is solved using mathematical programming methods. Novel techniques are employed to solve the resulting non-linear programming problem which allow to achieve effective optimisation with satisfactory accuracy, robustness and computational efficiency. Particularly, the proposed solution strategy is generally applicable to any arbitrarily complex vehicle mathematical model. Car and circuit models are set up, and the optimisation program is applied to investigate the sensitivity of the vehicle performance with respect to vehicle design parameters, such as the yaw moment of inertia, the total mass and the weight distribution. Furthermore, the minimum time manoeuvring problem is solved for very different vehicle configurations. The optimisation program accurately quantifies the vehicle performance in terms of manoeuvre time, and the nature of the optimal solution is shown to be always in excellent agreement with the dynamic properties of the vehicle model. A part of the work is devoted to the development of a strategy to obtain an initial estimate of the racing line and of the vehicle lateral and longitudinal controls to be used at the start of the optimisation. Two algorithms to compute the racing line using on board measured data from the real car are presented. A new mathematical model for the vehicle steering control is derived. The model uses multiple preview information of the intended path. Its structure derives from linear optimal preview control theory, but it is adapted to deal with non-linear vehicle operations arising from the inevitable tyre force saturation in vigorous manoeuvring. The excellent path following capability of the model is demonstrated by solving various path following tasks involving moderate manoeuvring and racing speeds.

36. Correlation vs. exchange competition drives the singlet–triplet excited-state inversion in non-alternant hydrocarbons.

Author

Sandoval-Salinas, M. E., Ricci, G., Pérez-Jiménez, A. J., Casanova, D., Olivier, Y., and Sancho-García, J. C.

Abstract

In this work, we focus on the understanding of the driving force behind the S1–T1 excited-state energy inversion (which would thus violate Hund's rule, making the S1 state lower in energy than the T1 state) of two non-benzenoid non-alternant hydrocarbons, composed of odd-membered rings. The molecules considered here have identical chemical composition but different atomic configuration in space. The delicate interplay between structural and electronic factors that might induce inversion and its energy extension, only by a few meV, is systematically investigated here by state-of-the-art calculations. Qualitative and quantitative accurate predictions are obtained employing post-HF methods, thanks to the balanced and careful inclusion of electron correlation effects. The obtained results might guide and rationalize new searches for molecules violating Hund's rule, concomitantly demonstrating the importance of key contributions from the theoretical method of choice.

39. Digital platform to assess risk to natural hazards in Mexico city, Mexico

Author

Novelo Casanova, D. and Suarez, G.

Abstract

To build disaster resilience, the National Autonomous University of Mexico and the Mexico City’s Secretariat of Education, Science, Technology, and Innovation, supported a project to develop a digital platform to assess risk to natural hazards in Mexico City. This platform is based on a Geographical Information System (GIS) and its main purpose is to identify the associated risk to the following natural hazards: earthquakes, volcanic eruptions, floods, mass movement processes, forest fires, and land subsidence. Besides characterizing the local hazards for different return periods, social vulnerability was determined using thirteen indicators from data of the 2010 Mexican Census of Population and Housing. We recognize social vulnerability as those social conditions that make a community susceptible to be damaged by a hazard and it is an inherent characteristic of society. Population and critical facilities (hospitals, schools, telecommunications, etc.) were considered as exposed elements. “Social risk” is expressed using a qualitative spatial multi-criteria evaluation technique by superimposing the calculated GIS’s raster of the social vulnerability over individual hazard rasters. The resulting values measure the “likelihood of risk”. Both, vulnerability and hazard, were classified into five categories with values from 1 to 5, where 1 is low and 5 very high. As a result, we obtain a meshing array that reflects the likelihood of social risk for specific hazards. The main purpose of this tool is to provide local authorities elements for land use regulations and urban development by strengthening their prevention and mitigation actions., The 28th IUGG General Assembly (IUGG2023) (Berlin 2023)

Abstract

Comprehensive evidence-based guidelines for the practice of pancreas transplantation are yet to be established. The First World Consensus Conference on Pancreas Transplantation was convened for this purpose. A steering committee selected the participants and defined the questions to be addressed. A group of literature reviewers identified 597 studies to be included in summaries for guidelines production. Expert groups formulated the first draft of recommendations. Two rounds of discussion and voting occurred online, using the Delphi method (agreement rate ≥85%). After each round, critical responses of experts were reviewed, and recommendations were amended accordingly. Recommendations were finalized after live discussions. Each session was preceded by expert presentations and a summary of results of systematic literature review. Up to three voting rounds were allowed for each recommendation. To avoid potential conflicts of interest, deliberations on issues regarding the impact of pancreas transplantation on the management of diabetes were conducted by an independent jury. Recommendations on technical issues were determined by experts and validated using the Appraisal of Guidelines for Research and Evaluation (AGREE) II instrument. Quality of evidence was assessed using the Scottish Intercollegiate Guidelines Network (SIGN) methodology. Each recommendation received a GRADE rating (Grading of Recommendations, Assessment, Development and Evaluations).

Abstract

The First World Consensus Conference on Pancreas Transplantation provided 49 jury deliberations regarding the impact of pancreas transplantation on the treatment of diabetic patients, and 110 experts’ recommendations for the practice of pancreas transplantation. The main message from this consensus conference is that both simultaneous pancreas-kidney transplantation (SPK) and pancreas transplantation alone can improve long-term patient survival, and all types of pancreas transplantation dramatically improve the quality of life of recipients. Pancreas transplantation may also improve the course of chronic complications of diabetes, depending on their severity. Therefore, the advantages of pancreas transplantation appear to clearly surpass potential disadvantages. Pancreas after kidney transplantation increases the risk of mortality only in the early period after transplantation, but is associated with improved life expectancy thereafter. Additionally, preemptive SPK, when compared to SPK performed in patients undergoing dialysis, appears to be associated with improved outcomes. Time on dialysis has negative prognostic implications in SPK recipients. Increased long-term survival, improvement in the course of diabetic complications, and amelioration of quality of life justify preferential allocation of kidney grafts to SPK recipients.

Abstract

Bile duct injury (BDI) is a dangerous complication of cholecystectomy, with significant postoperative sequelae for the patient in terms of morbidity, mortality, and long-term quality of life. BDIs have an estimated incidence of 0.4–1.5%, but considering the number of cholecystectomies performed worldwide, mostly by laparoscopy, surgeons must be prepared to manage this surgical challenge. Most BDIs are recognized either during the procedure or in the immediate postoperative period. However, some BDIs may be discovered later during the postoperative period, and this may translate to delayed or inappropriate treatments. Providing a specific diagnosis and a precise description of the BDI will expedite the decision-making process and increase the chance of treatment success. Subsequently, the choice and timing of the appropriate reconstructive strategy have a critical role in long-term prognosis. Currently, a wide spectrum of multidisciplinary interventions with different degrees of invasiveness is indicated for BDI management. These World Society of Emergency Surgery (WSES) guidelines have been produced following an exhaustive review of the current literature and an international expert panel discussion with the aim of providing evidence-based recommendations to facilitate and standardize the detection and management of BDIs during cholecystectomy. In particular, the 2020 WSES guidelines cover the following key aspects: (1) strategies to minimize the risk of BDI during cholecystectomy; (2) BDI rates in general surgery units and review of surgical practice; (3) how to classify, stage, and report BDI once detected; (4) how to manage an intraoperatively detected BDI; (5) indications for antibiotic treatment; (6) indications for clinical, biochemical, and imaging investigations for suspected BDI; and (7) how to manage a postoperatively detected BDI.
