Registered report protocol: A scoping review to identify potential predictors as features for developing automated estimation of the probability of being frail in secondary care
Authors: van Dalen Dirk H. , Kerckhoffs Angèle P. M. , de Vries Esther 
Published: September 2022

Introduction
The impact of frailty surges, as the prevalence increases with age and the population age is rising. Frailty is associated with adverse health outcomes and increased healthcare costs. Many validated instruments to detect frailty have been developed. Using these in clinical practice takes time. Automated estimation of the probability of being frail using routinely collected data from hospital electronic health records (EHRs) would circumvent that. We aim to identify potential predictors that could be used as features for modeling algorithms on the basis of routine hospital EHR data to incorporate in an automated tool for estimating the probability of being frail.

Methods
PubMed (MEDLINE), CINAHL Plus, Embase, and Web of Science will be searched. The studied population consists of older people (≥65 years). The first step is searching articles published ≥2018. Second, we add two published literature reviews (and the articles included therein) [Bery 2020; Bouillon, 2013] to our search results. In these reviews, articles on potential predictor variables in frailty screening tools were included from inception until March 2018. The goal is to identify and extract all potential predictors of being frail. Domain experts will be consulted to evaluate the results.

Discussion
The results of the intended study will increase the quality of the developed algorithms to be used for automated estimation of the probability of being frail in secondary care. This is a promising perspective, being less labor-intensive compared to screening each individual patient by hand. Also, such an automated tool may raise awareness of frailty, especially in those patients who would not be screened for frailty by hand because they seem robust.

Conclusion
The identified potential predictors of being frail can be used as evidence-based input for machine learning based automated estimation of the probability of being frail using routine EHR data in the near future.

O historiador Joaquim de Carvalho (1892-1958) desenvolveu uma abrangente indagação acerca da problemática da consciência histórica, concedendo especial atenção à sua relação com a experiência humana e a temporalidade. Que relação manteve com o passado próximo (século XIX), o presente e o futuro? Se o historiador-cidadão foi inequivocamente um adepto de um ideário liberal e democrático, poder-se-á dizer que os seus estudos históricos são marcados por uma ideia pré-determinada de futuro?
Em que medida Joaquim de Carvalho prolonga a narrativa liberal e republicana da história de Portugal herdada do século XIX? Em que sentidos a ultrapassou, enunciando problemas e deixando pistas para o futuro? Pretende-se estudar a ferramenta conceptual, a visão que o historiador nos deixou da história de Portugal nos séculos XIX e XX, a sua recepção, bem como o modo como se relacionou com a experiência histórica e o tempo.

Splenic Artery Aneurysm Rupture in a Parturient - Case Report
Authors: Priyash Verma  , Lucy Bates  
Published: September 2022

Splenic artery aneurysm (SAA) is a rare clinical condition that is associated with a risk of rupture and catastrophic haemorrhage, and its incidence ranges between 0.01-0.09%.[1,2] Although a seemingly rare entity, SAA has been estimated to affect 20-40% of parturients with no other underlying medical problems.[3]
This has been attributed to the various hormonal changes that accompany normal pregnancy. Rupture of SAA has been described as either a single precipitous event or a two-staged phenomenon with the bleed being initially contained in the lesser sac with an apparent antecedent haemodynamically stable phase followed by cataclysmic decompensation when the contained bleed leaks into the greater sac. This can take anything between 6 – 96 hours.[4] However, in pregnancy, this process can be rapid. We present one such case of a parturient, with initially preserved haemodynamics, followed by rapid decompensation, with ultimately good maternal and neonatal outcomes.

Published: September 2022

Abstract
In this work, magneto-electro-mechanical size-dependent nonlinear vibration analysis of nanobeam embedded in multi-layer of Winkler, Pasternak, quadratic and cubic nonlinear elastic media is presented. A nonlinear partial differential equation of motion is derived using Von Karman geometric nonlinearity, nonlocal elasticity theory, Euler-Bernoulli beam theory and Hamilton’s principle. Additionally, the efficiency of multiple scales Lindstedt-Poincare method for the strong nonlinear and large amplitude systems is presented. It is established that the results of multiple scales Lindstedt-Poincare method are in good agreements with the numerical and exact solutions for the strong nonlinear problems. However, the classical multiple scales method fails and gives results with very large discrepancies form the results of the numerical and exact solutions when the perturbation parameter is large, and the nonlinearity terms are strong. The high accuracy of the results of multiple scales Lindstedt-Poincare method and its excellent ability to produce accurate results for all values (small and large) of perturbation parameter and the nonlinearity terms show the superiority of the multiple scales Lindstedt-Poincare method over the classical multiple scales method. Further results present the effects of the model parameters on the dynamic behaviour of the nanobeam. It is hoped that the present study will advance nonlinear analysis of the engineering structures.

Abstract
The current research investigated the utilization of fuel cells as an energy storage unit in microgrid energy system applications in an effort to enhance self-consumption of renewable energy. The prototype evaluation is constructed of solar photovoltaic and fuel cell energy storage units. The study utilizes experimental weather and electrical load data for household obtained at 1-min temporal resolution. The daily average energy consumption for the evaluated household was 10.3 kWh, with a peak power output of 5.4 kW and an annual energy consumption of 3757 kWh. The Solar System under investigation has a capacity of 3.6 kWp, while the fuel cell system has a capacity of 0–3 kW, allowing for effective integration with the photovoltaic system and a maximum renewable energy fraction. The research indicates that by installing fuel cells powered by hydrogen generated from renewable energy sources, self-consumption and self-sufficiency significantly increase. The annual energy flow demonstrated that the implementation of 2.5 kW fuel cells improved renewable fraction utilization from 0.622 to 0.918, while increasing energy self-consumption by 98.4% to 3338.2 kWh/year and self-sufficiency by 94.41% to 3218.8 kWh/year.
Research on stability of hydraulic system based on nonlinear PID control
Authors: Liu Tong 
Published: September 2022

Abstract
In order to avoid the interference of the excavator hydraulic control system by external factors, the output stability of the hydraulic control system has to be improved. The method introduces a nonlinear Proportional integral differentiation (PID) controller with deviation correction parameters through the simulation verification of the control effect and the creation of excavator hydraulic drive diagram. PID, whose full English name is proportional integral derivative, is a mathematical and physical term. The controller is modeled in Matlab/Simulink. Finally, the whole hydraulic system is co-simulated by the interface of AMESim and Matlab. The simulation results show that the system model realizes the co-simulation through the interface combination of the two software, which is more accurate than the traditional PID control, and the pressure and flow fluctuation are smaller, which can suppress the interference of external load mutation, and improve the stability of the hydraulic drive output of the excavator. The validity of the experiment is verified.
Learning User Plan Preferences Obfuscated by Feasibility Constraints

Published: September 2022

It has long been recognized that users can have complex preferences on plans. Non-intrusive learning of such preferences by observing the plans executed by the user is an attractive idea. Unfortunately, the executed plans are often not a true representation of user preferences, as they result from the interaction between user preferences and feasibility constraints. In the travel planning scenario, a user whose true preference is to travel by a plane may well be frequently observed traveling by car because of feasibility constraints (perhaps the user is a poor graduate student). In this work, we describe a novel method for learning true user preferences obfuscated by such feasibility constraints. Our base learner induces probabilistic hierarchical task networks (pHTNs) from sets of training plans. Our approach is to rescale the input so that it represents the user's preference distribution on plans rather than the observed distribution on plans.

Published: September 2022

La producción y comercialización de alimentos de primera necesidad de la economía local campesina de las regiones intermedias, ha permitido acceder a productos de alta calidad, mediante estrategias de abastecimiento para zonas apartadas, conformando redes de cooperación en zonas rurales. Este comportamiento se ha ido transformando con la presencia de autoservicios gestionados por la comunidad. El objetivo del estudio, es establecer mediante el análisis del caso cómo la economía local ha adaptado nuevos formatos para mejorar la eficiencia en la comercialización. Para la obtención de la información se empleó modelos mixtos, combinando enfoques cualitativo y cuantitativo. Se estudiaron dos poblaciones, 130 clientes y diez propietarios y/o administradores de autoservicios, en la segunda población se empleó un muestreo por conveniencia dada la ubicación de los autoservicios en la zona geográfica de interés. Se diseñó una encuesta estructurada dirigida a clientes, las variables sobre las cuales se indagó fueron 1) comportamiento de compra, 2) medios de promoción, 3) percepción del lugar. Para los administradores y/o propietarios de autoservicios, se estudiaron 1) prioridades administrativas del autoservicio, 2) proveedores, 3) atención al cliente, 4) planeación y proyección de ventas y 5) conocimientos financieros y normativos. Se logró identificar que la economía local se ha visto influenciada en las ciudades intermedias por otras formas de comercialización de productos de primera necesidad, especialmente por el acceso y la cercanía con los proveedores aspectos que se consideran una ventaja competitiva gracias al relacionamiento que se tiene con los productores locales, quienes ofrecen ventaja como mejor precio, mayores plazos y facilidades de pago. Se concluye que se requiere fortalecer cuatro procesos: administración/alta gerencia, gestión comercial, talento humano y gestión de las comunicaciones.

Authors: Anurag Aakriti , Singh Salomi , Kumar Sushil 
Published: September 2022

Background: Post-partum hemorrhage is the leading cause of maternal mortality worldwide. Use of uterotonic drugs in active management of third stage of labour has been found to be most effective in prevention of PPH. Aims and objectives were to compare the efficacy and safety of carbitocin and oxytocin for prophylaxis of post-partum hemorrhage after singleton, term vaginal deliveries.Methods: Prospective randomized interventional study of 250 women with singleton term pregnancies undergoing vaginal delivery at MGM Women and Children’s Hospital, Kalamboli from May 2021 to May 2022. Participants randomized into 2 groups, group A and B receiving carbitocin and oxytocin respectively. Post-delivery uterine tone, vaginal bleeding, change in Hb and PCV, occurrence of adverse effects used to assess efficacy and safety of both drugs.Results: Carbetocin was statistically equal to oxytocin in preventing uterine atony and hence PPH, with similar duration of uterotonic action and lesser requirement of other uterotonic drugs. There was no incidence of adverse effects in either group.Conclusions: Since carbetocin is an effective, room temperature stable uterotonic drug with minimal side effects, it can be beneficial for use in prevention of PPH in rural settings.
TRANSITIONS IN GLOBAL POLARITY AND THE UNITED STATES OF AMERICA’S STRATEGY TOWARD SOUTH ASIA
Authors: Malik Ahmed Ijaz , Mirza Muhammad Nadeem , Qaisrani Irfan Hasnain 
Published: September 2022

Purpose of the study: This study intends to explore the discourses on patterns of systemic polarity. The study of these discourses helps in the development of the discipline of International Relations. The study also explores the foreign policy of the United States - being the greatest power of the time and claiming to be the custodian of the prevailing international order – towards South Asia.
Methodology: This is a qualitative explanatory and exploratory study. The specific method utilized to conduct the study remains the discourse analysis.
Main Findings: The study finds that international polarity is a continuous process of transition. These are a combination of systemic and sub-systemic actors and factors that contribute to this transition.
Applications of this study: The study is useful for students and scholars of International Relations, Area Studies, Strategic Studies, and allied disciplines. It is equally useful for policy practitioners.
Novelty/Originality of this study: The discourses on patterns of international polarity have contributed to the development of International Relations as a discipline. A significant debate on the discourses of international polarity has been the pattern of post-Cold War and Post-9/11 orders. While there has been a relatively dominant claim that this era overall shows evidence of unipolarity; there is an equally influential claim that the international order appears multipolar. There is however a need to address a primary question that demands an inquiry into the type of multipolarity in the post-Cold War and post-9/11 eras as it is assumed that the dynamics of international order and great power rivalries in this era are significantly different from the earlier patterns of international multipolarity. This inquiry is informed by focusing on the policies of great powers toward south Asia and the transforming geostrategic and economic relations between significant South Asian states.

Published: September 2022

Purpose: Our aims were to determine the prevalence of physicians’ adherence to antithrombotic guidelines in the management of outpatients with chronic atrial fibrillation (AF) and to identify risk factors for nonadherence to treatment guidelines.
Methods: Data on drug treatment, stroke risk factors and psychosocial variables were analyzed descriptively in a cross-sectional communitybased multicentre study. Predictors for nonadherence with guidelines for antithrombotic prophylaxis of AF patients were identified using logistic regression.
Results: Of 413 outpatients with chronic AF attending the offices of family physicians, 184 (44.6%) were treated according to the American College of Chest Physicians (ACCP) 2001 guidelines. In the group of patients with a high risk of stroke (n=387), 178 patients (46.0%) received guideline-adherent treatment. 31 of the high-risk patients received coumarin although they had at least one contraindication. Multivariate analysis showed the presence of absolute contraindications to coumarins to be an independent predictor of guidelinenonadherent treatment.
Conclusion: To improve guideline-adherence in the antithrombotic treatment in AF outpatients, strategies involving individual assessment of the risks and benefits will need to be established and implemented.

Authors: Strahovnik Andrej , Fokter Samo K. 
Published: September 2022

Purpose: This nonrandomised study analyzed the results of treatment of painful vertebral fractures in patients with primary osteoporosis with balloon kyphoplasty and compared them with conventional management (control group).
Methods: Consecutive patients were enrolled from an outpatient orthopaedic department over a four month period. Eight patients were treated with balloon kyphoplasty and eight with a symptomatic approach (analgesics, bed rest, thoracolumbosacral orthosis). Outcome measures included back pain severity measured on a visual analog scale (VAS), activity level measured on a VAS, bed rest, the SF-36 medical outcomes survey, subject satisfaction, and radiomorphology.
Results: Patients reported severe back pain interfering with daily activities before treatment. Physical functioning and quality of life were also markedly impaired. Statistically significant (P < 0.05) improvements in pain and functional outcomes occurred after treatment in the kyphoplasty group. Minor improvements were noted in the control group. Clinical outcomes were significantly different between the groups (P < 0.05). Kyphoplasty increased the midline vertebral height of the treated vertebral bodies, whereas in the control group vertebral height decreased.
Conclusion: A positive effect of kyphoplasty over conventional treatment was observed on vertebral morphology and patient satisfaction, pain, level of activity, and overall health perception.

Published: September 2022

Purpose: We have previously shown that newly synthesized fluoro-glucopyranosyl derivatives of ketonucleosides represent a group of antiviral drugs potent against RNA viruses. The aim of the present study was to ascertain whether these compounds are equally efficient in combating DNA viruses in comparison with the commercially available drug ganciclovir.
Methods: As a study model, the pseudorabies virus (NIA3 strain) and pig kidney cells (PK-15) were used.
Results: Our results indicated that 1-(6-O-acetyl-3,4-dideoxy-3-fluoro-β-D-glycero-hex-3-enopyranosyl-2-ulose)-N4-benzoyl cytosine (compound 2) is a potent inhibitor of pseudorabies replication, with higher antiviral activity than was found for ganciclovir.
Conclusion: Compound 2 has strong antiviral activity against the DNA virus pseudorabies.
