Abstract	This paper analyses the current state of electricity prices for large industrial consumers in Spain and compares the regulatory framework with other main industrial countries in Europe. The cost of electrical energy is a key factor in a country's industrial competitiveness. In a regulatory context shaped by the new European regulation of the internal electricity market in Europe, it would be expected that electricity prices in the Member States will converge in the long term, reaching similar values throughout the European Union. However, the limited electricity interconnection capacity in the case of some countries, such as Spain, means that electricity market prices are higher than in many Member States. This means that electricity-consuming industries face problems of competitiveness due to their higher energy bill costs. This paper focuses on the current situation for large industrial consumers in Spain, studying the main causes of the differences with other European countries, as well as analysing the various support mechanisms that have been implemented at both the national and European levels. This study also discusses the future prospects and possible solutions and recommendations for energy policy to promote the competitiveness of large industry in Spain within the context of a single European market.

Abstract	Background: Anorectal fistula, which is a relatively common pathology, is the chronic manifestation of the acute perirectal process that forms an anal abscess. The development of a fistula after incision and drainage of an anal abscess is seen in approximately 26-37%. Its treatment is a relevant topic, and the role of the use of antibiotic therapy in its prevention remains controversial, after the publication of several studies with contradictory results and several methodological limitations. Our hypothesis is that the combination of amoxicillin and clavulanic acid will reduce the incidence of anal fistula. Method: The aim of this study is to evaluate the efficacy of antibiotherapy after surgical drainage of perianal abscess in the development of perianal fistula. The PERIQxA study is a multicenter, randomized, double-blind controlled trial. The study has been designed to include 286 adult patients who will be randomly (1:1) assigned to either the experimental (amoxicillin/clavulanic acid 875/125 mg TDS for 7 days) or the control arm (placebo). The primary outcome measure is the percentage of patients that develop perianal fistula after surgery and during follow-up (6 months). Discussion: This clinical trial is designed to evaluate the efficacy and safety of amoxicillin/clavulanic in the prevention of perianal fistula. The results of this study are expected to contribute to stablish the potential role of antibiotherapy in the therapeutics for anal abscess. Trial registration: EudraCT Number: 2021-003376-14.

Abstract	Finding an optimal bidding strategy for a wind farm in the electricity market is not straightforward due to the wind variability. This issue is becoming more relevant as renewable plants are more exposed to market signals. Considering the characteristics of the European markets, operators must submit the energy bidding between 12 and 36 h ahead the actual delivery time. This bidding can be adjusted later in any session of the intraday markets, but sometimes this is not enough to reduce significantly the deviation risk. This paper presents a practical application of a method to analytically calculate the optimal bidding of a wind power plant, based on the maximisation of the income function. The results show that, given the characteristics of the deviation markets in Spain, the optimal bidding strategy depends essentially on the deviation of the system. The proposed technique has been tested and validated in a real application by considering actual data for energy production and forecasts for an operating wind farm in Spain, as well as real market deviations and prices provided by the Spanish system and market operators; analysing the advantages of the proposed optimal bidding strategy over the most plausible option, based on bidding the forecasted energy.

Abstract	Introduction: acute diverticulitis is one of the most frequent underlying causes behind individuals attending the Emergency Room with abdominal pain. The most widespread therapy for acute uncomplicated diverticulitis includes outpatient treatment with antibiotics; however, several publications indicate that patients can also be successfully treated without antibiotics. The results of the implementation of this more recent protocol in two hospitals in Madrid are presented. Methods: an observational prospective study was performed. Participants were patients diagnosed with uncomplicated acute diverticulitis at two hospitals in Madrid, Hospital Universitario de Torrejón and Hospital Universitario Puerta de Hierro Majadahonda, between December 2018 and August 2021, treated on an outpatient basis without antibiotic therapy. The study group was compared with a control group, composed of patients diagnosed with uncomplicated acute diverticulitis and treated with outpatient antibiotic therapy at Hospital Universitario Puerta de Hierro between March 2015 and March 2018. Results: three hundred and sixty-one patients were included, 182 in the study group and 179 in the control group. Diverticulitis was persistent in 19 patients (10.4 %) in the study group, who were not treated with antibiotics, and in five patients (2.8 %) in the control group, treated with outpatient antibiotic therapy (p = 0.004). Recurrences occurred in 23 patients (12.6 %) in the study group, and in 53 patients (29.6 %) in the control group (p < 0.0001). The analysis of the complications found no significant differences between both groups (p = 0.109). No urgent surgical intervention or mortality was recorded in the study group. Conclusions: in our environment, symptomatic non-antibiotic treatment of uncomplicated acute diverticulitis cases is safe, without showing a higher rate of complications. Although, there seems to be a worse initial symptom control.

Article: New method to assess the long-term role of wind energy generation in reduction of CO2 emissions – Case study of the European Union

Abstract	Most existing works using a displacement estimation method to estimate the CO2 emissions abated by wind energy are based on the current operating principles of the power system. They consider a fixed displacement emission factor since wind energy is assumed to replace high-carbon generation. This method may be unsuitable in the long run when the energy mix of most countries becomes more decarbonised. Consequently, wind energy would replace those technologies becoming increasingly predominant in the future, i.e. lower polluting fossil fuels such as natural gas and even other less competitive low-carbon technologies. In order to consider this effect, this paper proposes a new method that estimates a range of potential CO2 emissions abated by wind energy based on two dynamic displacement emission factors, which are periodically updated according to the evolution of the future energy mix. Such factors represent an upper and a lower limit of CO2 emissions avoided. The method is validated in the case study of the European Union over the period 2015–2050. The results show that the annual displacement emission factor by wind energy may vary from about 422 to 741 t CO2/GWh in 2015 to around 222–515 t CO2/GWh in 2050. The total CO2 abatement ranges from about 6600 to 13100 Mt CO2 in the period 2015–2050.

Abstract	This paper presents a new approach for the optimization of the layout of offshore wind farms. Almost all previous work on optimal micro-siting for large offshore wind farms have been based on irregular arrangements of wind turbines. However, most offshore wind farms already built are configured in symmetrical/regular layouts. From a mathematical point of view, the geometrical relationships of such symmetrical layouts enable the problem to be defined by just a few variables. This presents a considerable advantage compared with irregular arrangements where the number of variables is directly linked to both the number of wind turbines and the number of cells in which the computational domain is discretized. In contrast, symmetrical layouts are more demanding with regard to the optimization process, since the problem constraints, such as the shape of the available exploration area to deploy the project, the maximum surface allowed, and the maximum number of wind turbines, drastically increase the non-linearity of the objective function, which affects the ability of the optimization algorithm to achieve the optimal solution. This work compares the behaviour of two meta-heuristic optimization algorithms (the Genetic Algorithm and Particle Swarm Optimization) in solving the addressed problem and, more importantly, it introduces a series of improvements on the objective function, which enhance the behaviour of the optimization algorithms when dealing with realistic constraints, such as the shape of the concession zone and maximum deployable area. Finally, the performance of the proposed methodologies has been tested under two situations. The first scenario is a small-sized hypothetical offshore wind farm. In the second scenario, the layout of a real project (Horns Rev 3 offshore wind farm) has been optimized and compared with the solutions proposed by the Danish transmission system operator. The results obtained show the ability of the proposed tools to successfully show the ability of the proposed tools to optimize offshore wind farms under realistic considerations.
