El sector eléctrico español ante el alza del precio del gas y las medidas públicas en respuesta a dicha alza
Authors: García Martínez Fernando , Pacce Matías
Published: August 2023

El incremento de los precios de la electricidad, que alcanzó su máximo en agosto de 2022, ha afectado de forma diversa a las distintas actividades que se desarrollan en el sector eléctrico español. Este artículo analiza el impacto de dicho incremento sobre el sector, distinguiendo entre empresas generadoras y empresas comercializadoras, con especial atención a los resultados de explotación. En particular, se analiza la influencia sobre dichos resultados de aspectos como i) la incidencia de los contratos a plazo con precio fijo; ii) la exposición asimétrica a los incrementos de precios en los mercados mayoristas, o iii) la pertenencia a grupos verticalmente integrados, en el caso de las empresas comercializadoras. Asimismo, se analiza el efecto sobre el sector de las medidas desplegadas por las autoridades con el propósito de mitigar el impacto del encarecimiento de la electricidad sobre los hogares y las empresas de nuestro país. Entre estas medidas destacan, por ejemplo, el mecanismo ibérico para limitar el coste del gas empleado en la producción eléctrica o la minoración del denominado «exceso de retribución» surgido como consecuencia del aumento del precio del gas. Adicionalmente, se analiza también el impacto del gravamen temporal que las empresas energéticas deben pagar sobre la cifra neta de negocios de los años 2022 y 2023.

Published: August 2023

Aims: Internet usage has become popular among children in the last decade. Little is known about how children should use the digital world. The present study aimed to investigate the relationship between Internet use, frequency of Internet use under parental supervision, and depressive symptoms in children.
Material and Methods: The prospective cross-sectional study was conducted on 79 children aged 7-18 years old and their families who applied to the pediatric clinics between March 2021 and June 2021. The participants completed an online questionnaire, including sociodemographic data, children’s Internet use, and the Children’s Depression Inventory (CDI). Children’s Internet use was asked with a questionnaire created by ourselves for this study.
Results: The present study found no significant relationship between Internet usage time and depressive symptoms in children. Nevertheless, we showed that children who used the Internet more frequently under parental supervision and used the Internet for study purposes had lower depressive symptoms (p=0.026, p<0.001).
Conclusion: Internet use under parental supervision might protect children against the harmful effects of the digital world.

Authors: KAYA Ahmet Turan , AKMAN Burcu , KAYA Veysel , ÇETİN Şirin
Published: August 2023

Background/Aims: In the literature, the temporal variation of CT severity score (CT-SS) values on consecutive CTs, which is an indicator of pneumonia severity, according to the presence of hepatosteatosis was not evaluated. We aimed to investigate the effect of hepatosteatosis on the temporal change of CT-SS in COVID-19 patients.
Material and Methods: Our retrospective study included 472 RT-PCR positive COVID-19 patients ( ≥ 18 years old) admitted to our hospital between December 2021 and January 2022. Chest CT severity scores ranging from 0 to 5 were assigned to each lobe of the lung and total CT-SS was obtained. For quantitative analysis, if the hepatic/splenic attenuation ratio was <1, hepatosteatosis was defined. Wilcoxon test was used to evaluate the temporal changes of CT-SS values relative to the presence of hepatosteatosis. p<0.05 was considered statistically significant.
Results: Of the total 472 patients, 255/472 (54%) were hepatosteatosis-positive. The frequency of hepatosteatosis was significantly higher in male patients, 167/255 (65.5%) (p<0.001). The mean age was 64.04±14.35 years. There was no significant difference between ICU admission and hepatosteatosis groups (p=0.269). There was no significant difference between mortality and the presence of hepatosteatosis (p=0.429). There was a significant increase between the 1st and the 2nd CT-SS in patients with hepatosteatosis (p<0.001). The increase in the second CT-SS was higher in patients with hepatosteatosis than in patients without hepatosteatosis.
Conclusion: Hepatosteatosis may be an indicator of poor prognosis in the temporal change of pneumonia severity in COVID-19 patients.

Authors: YILMAZ SEZER Neslihan , AKER Menekşe Nazlı
Published: August 2023

Aim: This study was conducted to determine facilities for maintaining genital hygiene and genital hygiene behaviors among women of reproductive age.
Materials and methods:This descriptive study was conducted with 301 women who presented to the gynecology outpatient clinic of a university hospital between August and October 2022. The study data were collected using a descriptive information form and the Genital Hygiene Behavior Scale(GHBS).
Results:Participants' mean scores were found as 50.30±5.10 on the hygiene habits sub-dimension, 33.96±4.32 on the menstrual hygiene sub-dimension, 12.56±2.28 on the abnormal finding awareness sub-dimension, and 96.82±9.04 on the total GHBS. The mean GHBS scores of women who had primary education, lived in a large family, did not work in a paid job, had not received genital hygiene education, found their genital hygiene knowledge inadequate, had financial difficulties and felt embarrassed when purchasing genital hygiene products, had a fear of menstrual blood leakage, and experienced blood leakage accidents were lower (p<.05). While the most frequently used product for menstrual hygiene by 97.7% of women was sanitary pads, they also reported using washable pads (.7%), old clothes (.7%), washable period underwear (.3%), cotton (.3%), and toilet paper (.3%). It was determined that all of the women knew sanitary pads, 37.9% vaginal tampons, 27.2% washable pads, 26.2% washable period underwear, 15.3% menstrual cups, and 6% menstrual discs.
Conclusion: In our study, although the mean scores of participants on genital hygiene behavior looked good, it was determined that the scores of some featured groups were low. In addition, it was determined that women did not have enough knowledge about sustainable hygienic products. Nurses and midwives should evaluate the genital hygiene behavior of the women who they provide care for and inform and provide them with counseling about deficient or faulty practices in terms of protecting and promoting their health.

Published: August 2023

Background: This study aimed to compare the outcomes of mitral valve replacement (MVR) using the intermittent simple suture technique versus the horizontal matrix suture technique with pledgeted in terms of paravalvular leakage and infective endocarditis.
Methods: A retrospective analysis was conducted on 422 patients who underwent MVR between 2019 and 2023. Patients were divided into two groups based on the suture technique used: group B (simple suture technique) and group P (horizontal matrix suture technique with pledgeted). Propensity score matching was performed to balance the groups, resulting in 62 case pairs for comparative analysis.
Results: There were no intraoperative mortalities, and the duration of cardiopulmonary bypass and cross-clamp time did not significantly differ between the two groups. No significant differences were observed in terms of total hospitalization time, early mortality, cerebrovascular events, and arrhythmias. Postoperative echocardiography revealed minimal paravalvular leakage in both groups, with non-serious leakage observed in 4 patients in group B and 2 patients in group P. The incidence of infective endocarditis was 1 in group B and 2 in group P. Hemolysis indicators showed higher mean values in the simple suture technique group, although not statistically significant.
Conclusions: The study findings suggest that there is no significant difference in the incidence of paravalvular leak and infective endocarditis between the intermittent simple suture technique and the horizontal matrix suture technique with pledgeted. Both techniques can be safely employed in MVR.

Published: August 2023

Objective: It is known that anxiety and depression are associated with sleep disorders and many systemic diseases. This study aims to analyse the relationship between anxiety, depression symptoms and sleep parameters among the patients subjected to polysomnographic recording.
Material and Methods: A total of 808 patients who were subjected to a polysomnographic recording were included in the retrospective cross-sectional and hospital-based study. Body mass index (BMI) was calculated. Anxiety and depression symptoms were evaluated using the Beck anxiety and Beck depression inventory. Patients were divided into groups according to anxiety and depression scores. The apnoea hypopnea index (AHI), oxygen desaturation index (ODI), and peripheral oxygen saturation (SaO2) were obtained from the polysomnographic recordings.
Results: In the study, there were 528 (65.3%) male and 280 (34.7%) female patients with the mean age 47.64 ± 12.25 (18-82). Depression was detected in 307 (38.0%) patients according to Beck depression score. Mild anxiety symptoms were detected in 516 (63.9%), moderate anxiety symptoms in 215 (26.6%) patients and severe anxiety symptoms in 77 (9.5%) patients according to Beck anxiety score. There was a statistical difference for all polysomnographic parameters in depression and anxiety severity groups (p=0.001). In patients with depression had lower free-T3 and higher C-reactive protein (CRP) levels (p=0.001, p=0.014). The difference between thyroid stimulating hormone (TSH) and FT4 levels was determined according to the severity of the depression (p=0.037, p=0.047). CRP was higher in patients with severe anxiety (p=0.008); and free-T3 was lower in patients with moderate and severe anxiety (p=0.003, p=0.001). In the logistic regression analysis, free-T3, minimum SaO2 and BMI had an impact on anxiety (p=0.002, p=0.033, p=0.031) and depression (p=0.001, p=0.017, p=0.035).
Conclusion: Anxiety and depression symptoms are affected by numerous factors, especially sleep characteristics. Minimum SaO2, CRP and free-T3 are main predisposing factors on anxiety and depression

Authors: GUMELER Ekim , BULUT Elif
Published: August 2023

Background/aims: Lymphoma is the most common orbital malignancy in adults. We aimed to investigate pretreatment MRI predictors of systemic involvement and early therapy response.

Material and Method: Histopathologically confirmed orbital lymphoma patients with MRI scans at the time of diagnosis and after treatment constituted the study group. Involvement of lacrimal gland, intraconal and extraconal fat, eyelid, optic nerve and/or optic nerve sheath, extraocular muscles, intraocular involvement and presence of bone destruction were evaluated from pretreatment MR scans by two radiologists. Measurements of ADC values of the mass and pons were collected and the ratio (rADC= lymphoma ADC/ pontine ADC) was calculated. Response to treatment was evaluated from the follow-up MR images.

Results: Twenty patients (F/M= 10/10, mean age 57.3 ± 19.7) constituted the study group and histopathologic diagnosis was predominantly B cell lymphoma, extranodal marginal zone lymphoma being the most common (n=12, 60%). The most commonly involved structures were extraconal fat tissue (70%), lacrimal gland (50%) extraocular muscles (40%). Intraconal fat involvement was significantly higher (p=0.017) in patients with systemic disease compared to localized disease. rADC values showed no difference between patients with systemic and localized disease or patients with complete or partial response (p>0.05).

Conclusion: Intraconal fat involvement of orbital lymphoma could predict a systemic disease. The predictive value of pretreatment ADC levels should be searched in larger future cohorts.

"There is significant variation in antibody levels among patients exposed to SARS-CoV-2 or following vaccination. However, the quantity of antibodies at which one is considered protected, or for how long they can provide it, is unclear. In general, it is presumed that antibodies wane over time, more notably around the 6 months mark following the second dose. Our study aimed to observe these processes dynamically, by tracking the variation of IgG anti-Spike protein antibody levels in a population of volunteers at the Cantacuzino National Military Medical Institute for Research and Development. A total of 1338 samples from 524 participants, either symptomatic or asymptomatic, were collected before vaccination and at predetermined intervals after the first and second dose, over a 10-month period (December 2020 - October 2021). The samples were tested via enzyme-linked immunosorbent assay (ELISA) method, using commercial Anti-SARS-CoV-2 QuantiVac ELISA (IgG) quantitative test kits - Euroimmun (Medizinische Labordiagnostika). The majority of participants were vaccinated with BNT162b2 (Pfizer BioNTech) (474 participants – 90.46%). Samples were grouped according to the length of time between exposure (infection or vaccination) and testing, along with exposure type (vaccinated, vaccinated with prior infection, unvaccinated with prior infection). The data suggests that vaccinated participants, with or without a history of infection, held higher antibody levels compared to unvaccinated participants with a history of infection. A decline in antibody levels over time in all test groups was noted, though less steep among participants with a history of infection."

Authors: Zhang Heng , Fu Wei , Wu Ke
Published: August 2023

With a large number of applications of target detection in daily life, the performance requirements of target detection are constantly improving. Many challenges about target detection have been put forward constantly, such as imbalanced samples, fewer pixels, and occlusion of the detected target, all of which bring difficulties for the model to correctly identify the target. Small target detection has always been a difficult point and research hotspot. In recent years, many algorithms for small target detection have been proposed, such as data enhancement, feature fusion, attention mechanism, and super-resolution network structure. According to the characteristics of different network structures, the training strategy can be appropriately adjusted and then applied to different environments, which can greatly improve the detection accuracy of small targets. This paper will introduce the data sets and related small target detection algorithms proposed in recent years, and classify, analyze, and compare the corresponding training strategies.

We report the fabrication of hexagonal boron nitride (hBN) thin films over a sizable area (4 cm2) on a glass substrate by adjusting the deposition time during the radio frequency magnetron sputtering process. As-prepared hBN films were characterized using Raman spectroscopy, and we found the distinctive E2g vibration band at 1366 cm-1, which ensures the presence of hBN in its bulk form. AFM was used to examine how the deposition time affected the surface morphology. It has been found that the sputtered film is made up of large (about 1 μm) hBN flakes. Impedance measurements were made to determine the dielectric parameters of the hBN films. The specific capacitance of the hBN films is found to be 0.04 μF/cm2, and their resistances have been found to be as high as 105 Ω. This study shows that for an hBN film to have a high specific capacitance, less deposition time is needed during the sputtering process.

Authors:   Department of Computer Science, Asansol Girls’ College, Asansol, West Bengal, India, Ghanty Pradip
Published: August 2023

The disease of Alzheimer is a progressive neurological disease. In Alzheimer's disease, as neurons are injured and die throughout the brain. Dementia is the most important and primary concern for Alzheimer’s disease - there is deterioration in memory, thinking, behaviour and the ability to perform everyday activities. In the early stage of memory loss is the result of Mild cognitive impairment (MCI) and it also jeopardise the individual ability of performing his/her independently daily living activities. So, in later stage MCI patients may develop to Alzheimer disease (AD). In this paper a well-known Computational Intelligence tool called Artificial Neural Networks (ANNs) is used to predict AD from MCI samples. Two variants of ANNs - multilayer perceptron (MLP) and radial basis function (RBF) network are used for prediction. We have used 47 MCI samples (previously used by many researchers) for prediction problem. It has been observed that class distributions of MCI dataset are out of proportion i.e. lack of balance (imbalance). We have used oversampling algorithm with cross-validation for imbalanced MCI datasets to predict the developing of Alzheimer's or another dementia. In terms of prediction accuracy our findings are more relevant and it gives better results compared to previous studies which considered without imbalanced scenarios.

Inclusion criteria were clinically definite diagnosis of multiple sclerosis, 18 years of age or older and were able to give written informed consent. Cognitivefunction was evaluated by the Montreal Cognitive Assessment (MoCa) screening test. Quality of life was evaluated by SF36 questionnaire. Results: 88.33% of patients had cognitive impairment with 68.33% with mild cognitive impairment. Abstraction (60,83%), language (56,66%), executive functions (53.66%) and delayed recall (28.33%) were rated the worst. The median value of SF-36 score was 54.1 (27.7-70.01). The lowest results were achieved in the QOL domains of psycial limitation with a median value of 12.5 (0-75) and emotional limitation 33.3 (0-100). It is found statistically significant correlation of the MoCa score with social functioning, energy, vitality and general health (p<0.05) and physical functioning (p<0.001) domains of quality of life, as well as with SF -36 total scores (p<0.05). Among group of patients with cognitive impairment, statistically significant positive correlation between cognitive status mental health HRQOL domain (rho=0.427; p<0.001) was found. Conclusion: Cognitive impairment is very often presented in patients with multiple sclerosis with significant contribution to a poorer quality of life. It is associated with physical and emotional limitations, as well as poorer mental health. Further studies are needed, especially when we take into account very important clinical and prognostic role of cognition in multiple sclerosis.
Intra-articular replacement of the caudal cruciate ligament using an UHMWPE ligament under arthroscopic guidance in a dog: A case report

Background:
As isolated ruptures of the caudal cruciate ligament (CdCL) are rare in dogs, there is no consensus on the indications and the gold-standard surgical technique for treatment.
Case Description:
A 2-year-old Shepherd dog with an isolated rupture of the CdCL was treated with a new surgical technique for synthetic reconstruction. Three bone tunnels were drilled in the femur and the tibia under arthroscopic guidance to make sure the anatomical insertions of the physiological ligament were respected. An Ultra-High Molecular Weight Polyethylene (UHMWPE) implant was fixed with interference screws to reconstruct the CdCL. A synovial inflammation remained present on radiographs for six months after the surgery, together with a mild lameness. However, the dog fully recovered clinically and recovered a normal level of activity after six months. LOAD results at six months and one year postoperatively were excellent.
Conclusion:
The use of an UHMWPE implant fixed with interference screws to reconstruct the CdCL allowed a return to full function of the knee without complications, despite a persistent synovial inflammation and mild lameness for a 6-month period after the surgery. The success of this isolated surgical technique could lead to improvements in the surgical management of CdCL rupture, if these initial results are confirmed by a prospective study with a larger number of patients.

We show that a software architecture based on machine learning and adaptive control advances makes self-tuning optics possible. Commercially available optical telecom components may be combined with servo controllers to develop a training and execution software module that can self-tune the laser cavity even when it is switched off. Mechanical and/or environmental disturbances may aid in frequency comb stabilization. An exhaustive search of state space is used in the algorithm training stage to find the optimum performance areas for one or more objectively interesting functions. The technique of implementation stage starts by identifying the variable space using a sparse sensing approach, then settles on a near-optimal solution and maintains it using the extremum seeking control protocol.
Die Frage der ethnischen Deutung der Zarubincy-und der Černjachov-Kultur in der neueren sowjetischen Literatur
Authors: Widera Bruno
Published: August 2023

Die Erforschung der Ethnogenese der Ostslawen und ihrer frühesten Geschichte hat in der Sowjetunion eine weit zurückreichende Tradition. Bei der Lösung dieser Frage mit Hilfe archäologischer Ergebnisse spielen heute die Zarubincy- und die Černjachov-Kultur eine große Rolle. Die archäologischen Erscheinungen beider Kulturen werden kurz skizziert. Die Arbeiten derjenigen sowjetischen Archäologen, die die Zarubincy-Kultur als slawisch ansehen und in denen Argumente für eine Kontinuität von der Zarubincy- zur Černjachov-Kultur vorgetragen werden, werden hervorgehoben. Die Černjachov-Kultur wurde nach allgemeiner Auffassung der sowjetischen Forschung nicht nur von slawischen Elementen getragen. In der deutschsprachigen Slawenforschung wurden die Ergebnisse, die die sowjetische Archäologie bei der Erforschung der Ethnogenese der Ostslawen erzielte, bisher zu wenig beachtet, in der BRD sogar entstellt wiedergegeben.

Circulating biomarkers of mortality prediction in patients undergoing liver transplantation due to hepatocellular carcinoma
Authors: Lorente Leonardo
Published: August 2023

There are different macromorphological factors obtained prior to liver transplantation (LT) to predict the prognosis of hepatocellular carcinoma (HCC) patients undergoing LT. The use of blood biomarkers could help improve the prognosis prediction of these patients. Blood levels of alpha-fetoprotein (AFP) are the first and most studied prognostic blood biomarkers of HCC patients undergoing LT. This review is to summarize the evidence of prognostic blood biomarkers for HCC patients undergoing LT. A higher mortality rate has been found with high blood levels of neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), systemic immune-inflammation index (SII), C-reactive protein (CRP), albumin-bilirubin (ALBI) score, des-gamma-carboxy prothrombin (DCP), lactate dehydrogenase (LDH), gamma glutamyl transpeptidase (GGT), fibrinogen, vascular endothelial growth factor (VEGF), homocysteine, Golgi protein 73 (GP73), substance P, soluble CD40 ligand (sCD40L), caspase-cleaved cytokeratin (CCCK)-18, caspase-3, malondialdehyde and oxidized guanine species (OGS). A higher mortality rate has been found with low blood levels of lymphocyte-to-monocyte ratio (LMR), PD-L1, Galectin-9, total antioxidant capacity (TAC) and melatonin. Moreover, some studies with small sample sizes associate blood levels of metabolites and microRNAs (MIRs) with the prognosis of HCC patients undergoing LT. More research is warranted to determine the possible utility of these biomarkers to predict the prognosis of HCC.

Reform of Corruption Criminal Law: a Study of Corruptor Asset Application Law in Indonesia
Authors: Soedirjo Achmad Taufan , Santiago Faisal , Jaya Surya
Published: August 2023

The development of a new criminal law system in Indonesia still aims to reveal the crimes committed, find the perpetrators, and punish them with criminal sanctions, especially "corporate punishment", which includes imprisonment and the death penalty. Meanwhile, the issue of international law development, such as the issue of confiscation of proceeds of crime and tools of crime2, has not become an important component in the Indonesian criminal law system. The purpose of this study is to determine the extent to which the reform of corruption criminal law can be carried out, especially in terms of asset forfeiture of corruptors. The research method used is normative research with a legal approach and conceptual approach. The reform of corruption criminal law must provide a clear definition of asset forfeiture of corruptors. The definition must include various types of assets, both tangible and intangible, which are illegally obtained through acts of corruption. The research method used is normative research with a legal approach and conceptual approach. The results of the discussion show that the reform of corruption criminal law regarding the seizure of corrupt assets can strengthen corruption eradication efforts and improve the existing seizure mechanism. The legal reforms carried out include Law Number 31 of 1999 concerning Eradication of Corruption (PTPK Law); Law Number 8 of 2010 concerning Prevention and Eradication of Money Laundering Crimes (TPPU Law); Presidential Instruction Number 3 of 2018 concerning Increasing the Role and Optimizing Community Participation in Corruption Eradication; Government Regulation Number 13 of 2021 concerning Procedures for Forfeiture of Corruption Proceeds.
