Interpretation Algorithm of Linear and Non-elementary Linear Regression Models Under Multicollinearity Conditions
Authors: Bazilevski M.P.
Published: December 2023

When constructing machine learning models, more and more researchers come to understanding that in addition to the accuracy of the model, its interpretability is also important, that means the degree of understandability to a person. Currently, a new field is being formed in science - interpretable machine learning. This article is devoted to the study of linear regression models interpretation questions. Traditionally, linear regressions are interpreted in terms of weak correlation of explanatory variables. In this case, according to a well-known pattern, it is possible to explain the influence of each input variable on the output variable. Often the explanatory variables are highly correlated with each other. In such a situation, it is recommended to exclude strongly correlated variables, that leads, firstly, to a decrease in the model quality, and secondly, to integrity loss of the study and the interpretation of a process or phenomenon under study. In this paper, we propose an algorithm for interpreting a linear regression constructed for any degree of explanatory variablecorrelation. The algorithm gives the traditional interpretation of linear regression with weak correlation of all explanatory variables, while in case of strong correlation, as it follows from the theorem proved in the article, regression interpretation with several variables is reduced to interpreting an equation with one variable, without losing information about the relationships between pairs of explanatory variables. The algorithm can be used not only for simple linear regressions, but also for non-elementary ones, containing, in addition to explanatory variables, their pairs transformed by means of binary operations min and max. The operation of the algorithm is demonstrated on specific examples.
Rejuvenating Aged Asphalt Binder from Reclaimed Asphalt Pavement through the Utilization of Waste Cooking Oil
Authors: Asim Muhammad
Published: December 2023

Abstract: This study investigates the use of waste cooking oil to rejuvenate aged asphalt binder from reclaimed asphalt pavement (RAP) in Peshawar, aligning with National Highway Authority (NHA) standards. Aged binder from RAP near Zintara Residence on Peshawar's Ring Road was combined with filtered cooking oil from local restaurants in varying proportions (1% to 5%). The rejuvenated binders underwent extensive physical and rheological tests, showing that certain fractions of cooking oil effectively revitalized the old binder, aligning it with virgin bitumen qualities. Superpave experiments on RAP mixes (30%, 40%, 50%) demonstrated comparable performance to fresh asphalt, particularly at 30% to 40% replacement levels. The results suggest that revitalized RAP holds promise as a sustainable alternative, enhancing asphalt mixes for road construction.
Experiências inventivas na formação em saúde: um debate sobre políticas cognitivas
Authors: Ferreira Suiane Costa
Published: December 2023

A política cognitiva gera espaços de agenciamentos que engendram modos de ensinar e de produzir conhecimento. Este artigo objetiva descrever experiências de ensino produzidas por docentes da área da saúde, mediadas por distintas tecnologias, que possibilitaram a experimentação de uma aprendizagem inventiva, conformando uma política cognitiva que direciona o professor para diferentes modos de ensinar e de se relacionar, seja com seus pares, com os estudantes ou com a tecnologia, contribuindo para a transformação dos regimes cognitivos. Este é um estudo de caso apoiado no método cartográfico. Percebe-se que, quando os professores produzem práticas pedagógicas não lineares e problematizadoras, estabelecem contradições com o instituído, possibilitando o estabelecimento de controvérsias, de articulações e novas associações entre alunos, professores e tecnologias muito mais potentes para a formação de profissionais da saúde com perfil humanista, crítico, inventivo e colaborativo.
Современная архитектура в России: опыт тридцатилетия
Authors: Есаулов Георгий , Есаулова Людмила
Published: December 2023

Тридцатилетний период новейшей истории российской архитектуры постепенно обретает черты этапности. Радикальные перемены в России в 90-е годы XX века с появлением частной собственности и переходом к индивидуальному проектированию отмечены возникновением целого веера направлений в архитектурном творчестве. Преобладающим было обращение к историческим стилям на принципах постмодернизма. В 2000-е годы создаётся новая ситуация, обусловлен-ная рядом новых факторов и задач. Ведущими становятся направления, появившиеся ситуативно в начале 1990-х годов и опирающиеся на принципы новаторских направлений: хай-тека, минимализма, неомодернизма, попыток актуализации авангардных течений. В 2010-е годы именно они воплощают социально-экономический заказ и наполняются инженерно-технологическими новациями, обусловленными обращением к стратегии устойчивого развития. Условность деления на этапы объясняется многообразием и архитектурных поисков, и параллельно идущих социально-экономических процессов, и инженерно-технического прогресса.

An analysis of the impact of external shocks on the economic performance index of the European Union countries: The case of the Russian invasion of Ukraine
Authors: Misini Shkumbin , Tosuni Gëzim
Published: December 2023

This study will use secondary data to assess the economic performance of European Union (EU) countries over the last two decades, from 2000 to 2022. The Economic Performance Index (EPI) is produced using numerous critical factors, including unemployment, inflation, public debt, and economic growth. This study will first examine the influence of COVID-19 on the performance of these countries before going on to examine the impact of Russia’s invasion of Ukraine. The war has had a direct impact on the world economy, notably in Asian countries (Umoru et al., 2023). Furthermore, the pandemic has harmed all economic sectors in EU countries (Su et al., 2022). The use of graphs and the interpretation of descriptive statistics will be used to investigate the influence of the aforementioned exogenous shocks. Furthermore, panel data regression analysis between EPI and average earnings in the public and private sectors will be used to examine whether economic performance transfers into the real economy. The findings appear to indicate that both external shocks have had a negative impact on the economic performance of all 27 EU member countries, but in the case of COVID-19, economies reliant on tourism have suffered the most, while the Russian invasion of Ukraine has put more pressure on Hungary, the Czech Republic, and the Republic of Ireland. This research will add to the growing body of post-Russian invasion literature.

Published: December 2023

El déficit de hormona de crecimiento (GH) es una endocrinopatía de baja prevalencia y aún menosfrecuente, en el perro adulto (adquirida). Se reporta el caso de un canino hembra, de raza Golden retriever,de 7 años, castrada. El motivo de consulta es la pérdida severa de pelo. El pelo remanente, estaba reseco ydecolorado. Asimismo, esta perra presentaba atrofia de los músculos temporales y el propietario refería unestado de apatía.Al momento de la consulta, estaba siendo tratada con levotiroxina 600 µg cada 12 h por un período de 6meses sin resultados y pese a que las concentraciones de TSH y T4 total estaban dentro del rango dereferencia. Se volvieron a reevaluar las hormonas del eje tiroideo y se solicitaron también las hormonas deleje adrenal (ACTH, cortisol y relación cortisol: creatinina en orina); todas dentro del rango de referencia.Así mismo se solicitó ecografía de la glándula tiroidea y de las glándulas adrenales, siendo sus morfologíasy tamaños normales. Antes estos resultados, se decidió evaluar el eje somatotropo por medio de la mediciónde IGF-1, estimulación con xilacina y tomografía axial computada de la región selar (hipófisis). Laconcentración de IGF-1 fue <15 ng/mL (200-400 ng/mL) y no hubo respuesta al estímulo con la xilacina,lo que es indicativo déficit de GH. La tomografía informó de la presencia de un adenoma de 5,25 x 4,86mm (P/B=1,1). Se indicó el tratamiento con hormona de crecimiento y a los 2 meses ya se hacía notable elcrecimiento del pelo, la mejora en la actitud cognitiva, y un aumento de las concentraciones del IGF-1 a95,4 ng/mL.CONCLUSION: Este caso ejemplifica la importancia de una aproximación diagnóstica integral, laconsideración de diagnósticos menos comunes y la necesidad de una atención veterinaria especializada paraabordar eficazmente problemas de salud complejos en animales.

Thriller of the Zadar nun Cattarina Marchi
Authors: Dundović Zdenko
Published: December 2023

In a paper on the nuns compelled to enter monastic life in the Venetian Republic, published in the Sixteenth Century Journal, Anne Jacobson Schutte cited, among others, the case of the Zadar nun Cattarina Marchi. Zadar archival sources offer new insights about the Zadar nun, provide answers to the questions posed by Schutte and shed new light on Marchi's petition for the annulment of monastic vows. The analysis and synthesis of archival sources in Zadar, as well as other archival sources, have changed the entire narrative surrounding the nun Marchi, justifying the doubt about the authenticity of the story (true story) regarding her forced entry into the monastery. It will be shown that her case must be considered in the context of economic, social and religious relations between the Zadar nobility and its middle class in the 16th-18th century, especially from the point of view of inalienable inheritance rights, known as fedecommesso.
Cesarčev Kvaternik
Authors: Protrka Štimec Marina
Published: December 2023

Historiografski utemeljen i književnopovijesno relevantan, dramski tekst Augusta Cesarca Sin domovine (1940.) već uvodnom autorskom bilješkom upućuje na osobnu dramu Eugena Kvaternika koja se razvija u srazu njegova habitusa, ideala i društvenih i političkih okolnosti koje će ga voditi do realizacije „čina” u Rakovičkoj buni i tragičnoga kraja. Postavljajući Kvaternika uz bok idealistima i revolucionarima njegova doba, a u kontrastu prema oportunizmu i korumpiranosti vladajuće političke elite, ali i podupirućih društvenih struktura, Cesarec stvara tragičnu figuru povijesne ličnosti kojom se istovremeno osvrće na nasljeđe Francuske i obzore Oktobarske revolucije. U članku se njegov pristup predstavlja kao izraz generacijskoga i osobnoga angažmana koji se u književnoj povijesti nadovezuje na liniju promišljanja politike, pravednosti i otpora, granica opravdanoga nasilja, progresa i povijesnoga usuda koja se u hrvatskoj književnosti može pratiti od Mažuranića i Kranjčevića pa do generacije mladih i samoga Cesarca. Cesarčev Sin domovine u tom kontekstu funkcionira kao modernističko uobličenje drame istaknutoga pojedinca čiji je individualizam preduvjet svakoga kolektivnog napretka.
Research of melting state identification and process performance based on selective laser melting acoustic signals
Authors: Chen Dongju , Wang Anqing , Wang Peng , Li Na
Published: December 2023

An acoustic signal acquisition experiment platform was constructed to gather the acoustic signals throughout the formation of 35 single-tracks of a 120 mm length copper-tin alloy in order to monitor and precisely manage the selective laser melting (SLM) forming process and enhance overall quality. The monitoring of the SLM forming process includes the analysis of the time and frequency domains, the extraction of the SLM process features using linear prediction techniques, and the development of support vector machine (SVM) model, back-propagation (BP) neural network models, and convolutional neural network models. The results show that the over-melted state can be identified by extracting time and frequency-domain features over a given range, but the normal and unmelted states are difficult to distinguish. The convolutional neural network model had a recognition rate of 99%, the BP neural network had an effective recognition rate of 90%, and the SVM model had a combined classification rate of 83.14% for the three states after optimization. In contrast, the convolutional neural network model performs best in monitoring and offers a framework and point of reference for acoustic signal analysis and online SLM quality monitoring.

Published: December 2023

The Franssen illusion, or Franssen effect (FE), is one of the auditory spatial illusions. Few studies have explored the FE, and the mechanisms underlying it remain unknown. The present study was conducted to clarify the FE occurrence with different tasks and presentation modes in young adults. It also sought to investigate possible neurophysiological similarities between interaural time difference (ITD) cue processing and FE perception. FE perception was evaluated using two different tasks and two presentation modes (i.e., insert phones and loudspeakers). Sound reflections (reverberation) were presented in the diffuse field (loudspeaker mode). ITD performance was investigated using different stimuli delivered via insert phones. No significant difference between the two FE perception tasks was found ( F 1,25 = 0.138, p = 0.713). However, the FE perception showed a significant difference between the two presentation modes (F 1,25 = 434.03, p < 0.001). Spearman’s correlation did not reveal a significant relationship between FE perception and ITD scores ( p > 0.05). The current findings show the importance of reverberation in the FE occurrence. Also, the non-significant correlation between the results of the behavioral binaural temporal resolution test and FE perception in young people with normal temporal resolution may indicate that room reflections (reverberation) complicate the ability to process ITDs (rather than poor ITD processing for the “steady state” portion of signal).
Clonal hematopoiesis of indeterminate potential: implications for the cardiologists

Published: December 2023

Myeloproliferative neoplasms, including polycythemia vera, essential thrombocythemia, and myelofibrosis, are characterized by somatic gene mutations in bone marrow stem cells, which trigger an inflammatory response influencing the development of associated cardiovascular complications. In recent years, the same mutations were found in individuals with cardiovascular diseases even in the absence of hematological alterations. These genetic events allow the identification of a new entity called ‘clonal hematopoiesis of indeterminate potential’ (CHIP), as it was uncertain whether it could evolve toward hematological malignancies. CHIP is age-related and, remarkably, myocardial infarction, stroke, and heart failure were frequently reported in these individuals and attributed to systemic chronic inflammation driven by the genetic mutation. We reviewed the connection between clonal hematopoiesis, inflammation, and cardiovascular diseases, with a practical approach to improve clinical practice and highlight the current unmet needs in this area of knowledge.

In the latest European guidelines for the management of valvular heart disease, mechanical valve prostheses maintain a strategic role, particularly for certain patient subsets and age groups. Despite the high number of devices implanted in clinical practice, particularly in non-European and North American regions, current scientific literature and debate seem to suggest a limited use of mechanical heart valves. The cardiac surgery community seems to be highly interested in biological and transcatheter valve prostheses but less interested in mechanical heart valves, including possible strategies for self-management of anticoagulation therapy. In this respect, the Italian Society of Cardiac Surgery (SICCH), in particular the Italian Group of Research for Outcome in Cardiac Surgery (GIROC), has promoted a survey among its members to stimulate the interest in this topic and express their opinion on this issue that, due to the prevalence of the affected population and the new treatment options for improving patients’ quality of life, should be more appraised and debated in the cardiac surgery community. The recorded results, obtained on the answers to 111 questionnaires, seem to divide the specialists into ‘pros’ and ‘contras’ on a useful tool for the entire cardiac surgery community. For this reason, SICCH proposes in conclusion to declare its unified and institutional opinion on this topic.
Long-term mitral valve repair outcomes and hospital volume: 15 years’ analysis of an administrative dataset
Authors: Saitto Guglielmo , Mariangela D’Ovidio , De Luca Leonardo , Lio Antonio , Ranocchi Federico , Davoli Marina , Musumeci Francesco
Published: December 2023

Background

Procedural volume has been documented as an important contributor to operative outcomes for most complex surgical procedures. Mitral valve repair (MVRep) has been associated with excellent results, and it is increasingly adopted in many cardiac surgical centers. We sought to investigate if procedural volume is associated with better clinical long-term outcomes after MVRep.

Methods

We analyzed the 10-year outcomes after MVRep by procedural volume for each cardiac surgery center in an Italian Region, Lazio, during the last 15 years, using a regional administrative dataset.

Results

Between 2006 and 2020, 4961 patients were treated in seven cardiac surgery centers for an isolated mitral valve surgery (2677 underwent MVRep). At multivariate analysis, mitral valve replacement (MVR) (vs. MVRep) resulted one of the independent predictors of 30-day mortality [adjusted odds ratio (OR) 3.40; 95% confidence interval (CI) 1.96–5.90; P < 0.0001]. Notably, a clear association between hospital volume of mitral valve surgery (>40 per year) and high rate of MVRep (>50%) was found. At 10 years, the incidence of mortality and the rate of death and rehospitalization for heart failure after MVRep were significantly lower in high-volume vs. low-volume hospitals.

Conclusion

Our data suggest that hospital volume is associated with a high rate of MVRep and long-term benefits in terms of mortality and recurrence of heart failure.
The EU Accession to the Istanbul Convention: The Argument From the ‘common Accord’ Practice
Authors: Kubacka Karolina Kaja
Published: December 2023

The main purpose of this article is to analyse the Council’s practice of ‘common accord’ as the argument behind the tardiness of accession to the Istanbul Convention by the European Union. It presents how political and legal factors condition the accession of the Istanbul Convention by the European Union. In light of the Court of Justice Opinion 1/19, there are no legal obstacles to the accession; therefore, the tardiness of ratification arose from the political context, which consists of the EU’s constitutional crisis, populists in power, and liberal decision-makers succumbing to them. Based on the sociological assumption, the case study confirms the existence of the practice of ‘common accord’ as an effect of the conditions mentioned above. Nevertheless, the social need to access the Istanbul Convention is urgent.
Teaching Natural Sciences and Possible Paths to Strengthen Cultural Capital
Authors: Santos Welson Barbosa , Martins Rone Rosa , Motta Maria Carolina Carvalho , De Souza Thomas Magno Barbosa
Published: December 2023

Theoretical framework: The concept of Capital that we take as a reference comes from Pierre Bourdieu in the reality of rural social spaces and the basis is that cultural differences can intervene in people's future and opportunities. If it doesn't exist, the chances of academic success and entry into higher education fall, as does the quality of life.
 
Methodology: with a qualitative profile, discourse analysis was the reference once the testimonies of 23 peasant students were accessed. With the speeches, the search was for the meanings in the constitutivity of the subjects and their speeches, refusing univocal, easy explanations and the insistent search for the ultimate and hidden meaning of things.
Results and conclusion: regarding economic capital, we perceive its existence in the form of different factors of production, for example, land, factories, work and the set of economic goods such as money, heritage, material goods of the family in the countryside. But it was in the symbolic and cultural capital that the peasant reality could be evaluated.
 
Implications of the research: although social movements and their fight for rights, both in the field of education and to conquer the right to land, culture, history and memory is historic, education can break with issues that are not yet so well resolved.
The Free Economic Zone of Manaus Vis-à-Vis the 2030 Agenda for Sustainable Development
Authors: Feltre Cristiane , Branchi Bruna Angela
Published: December 2023

Purpose: This study aims to analyze the evolution of sustainability indicators within the Free Economic Zone of Manaus (Zona Franca de Manaus - ZFM), with a specific focus on workforce engagement in the manufacturing sector.
 
Method/design/approach: Employing descriptive research methods, this research equips both public and private organizations with evaluation tools to assess industrial employment's quality in the context of sustainable development. The study emphasizes the importance of monitoring sustainable development indicators at various geographical levels to facilitate effective corrective strategies.
 
Results and conclusion: The public policies adopted in the ZFM, although generating economic growth, had adverse effects on other social indicators such as quality of life, urban sprawl, and population explosion. These outcomes indicate a misalignment with the Sustainable Development Goals outlined in the 2030 Agenda. Notably, these misalignments are evident in the declining number of manufacturing plant employees, persistent gender-based wage disparities, a rise in workers in lower income brackets, and subsequently, a limited potential for local consumption.
 
Research implications: The ZFM exemplifies the vital role of public policy in driving development. While innovation in the ZFM is still at an early stage, there exists potential for linking economic innovation to improvements in quality of life and sustainable natural resource management.
 
Originality/value:  This analysis focuses on sustainability indicators to assess regional development, highlighting the significance of Sustainable Development Goals in evaluating the quality of development and monitoring the outcomes of public policy within the unique context of the ZFM.

Introduction. Sarcopenia is common among patients with liver cirrhosis (LC) and has a significant impact on the quality of life of patients, the nature of the course of the disease and mortality. The phase angle (PhA) is the arctangent of the ratio of reactive and active resistances for a variable frequency current obtained using bioimpedance analysis. Data on the relationship between PhA and sarcopenia are limited, so the analysis of this topic is the important step towards understanding the role of sarcopenia in LC.

The objective was to evaluate the relationship between the values of the phase angle and the index of skeletal musculature obtained by CT volumetry in patients with LC.

Methods and materials. The study included 15 patients diagnosed with LC. The anthropometric examination was carried out, followed by an assessment of the component composition of the patients’ body using the ABC-01 «Medass» device (STC Medass, Russia). According to the indications, all patients underwent CT of the abdominal cavity without contrast enhancement.

Results. Median and interquartile interval PhA (°): 5.3 [4.2–5.7] in men and 5.2 [4.9–6.1] in women, skeletal muscle index (cm2/m2): 51.82 [48.33–53.75] cm2/m2 in men and 44.114 [38.9–49.32] cm2/m2 in women. The correlation analysis revealed a positive correlation of the average strength between the skeletal muscle index (cm2/m2) and PhA (°): r=0.2619, p-value=0.036845.

Conclusion. Determination of the components of body composition and their relationship with the course of diseases in patients with LC may have practical application and requires further study.

Published: December 2023

Introduction. The relevance of the research is determined by the insufficient study of the psychological characteristics of female patients in the cosmetological clinic and the dynamics in the process of non-surgical correction and, in general, the psychological aspects of cosmetological treatment.

The objective was to study the dynamics of the psychological characteristics of female patients of a cosmetological clinic in the process of medical correction.

Methods  and  materials.  Using  psychodiagnostic  methods  “Neuropsychic  Adaptation  Test”  (NPA),  Wellness  Index (WHO-V),  Visual  Analogue  Scale,  Big  Five,  Quality  of  Life  Satisfaction  Questionnaire  (QL),  193  female  patients  of  the cosmetological clinic (mean age 39.19±0.8 years) were examined in the period before treatment and 3 months after it. Data processed by SPSS v. 25.0 using Pearson’s χ2 and Wilcoxon’s Z tests.

Results. The results showed statistically significant changes in the course of treatment of 11 out of 20 psychodiagnostic indicators reflecting the positive dynamics of the following psychological characteristics: the level of neuropsychiatric adaptation (р=0.014), the level of psychological well-being (р=0.000), perception of one’s appearance (р=0.000), individual characteristics of the personality “self-consciousness” (р=0.003) and “personal resources” (р=0.001), overall satisfaction with quality of life (р=0.000) and its individual components.

Discussion. There are showed limitations and research prospects associated with the further expansion of the range of studied psychological characteristics, their relationship with the severity of a cosmetic defect and, in a broader context - with the determination of the role of psychosocial factors in the mechanisms of development and the effectiveness of correction of facial skin defects.

Objective:
This study aimed to measure the barriers to breast reconstruction after mastectomy, with a particular focus on general surgeons in Saudi Arabia.
Methods:
This was an observational cross-sectional study conducted among general surgeons in Saudi Arabia from December 2022 to the end of June 2023. All participants completed a previously validated online self-administered questionnaire. The questionnaire included questions about access to breast reconstruction.
Results: A total of 190 participants were included, with almost half of them (44.2%) were younger than 30 years. Additionally, 51.6% participants were male. Further, results demonstrated that 48.9% physicians would always discuss the available options for breast reconstruction surgeries with all breast cancer patients, and 33.7% would always refer breast cancer patients to a plastic surgeon for consideration of breast reconstruction. In general, 68.4% participants in the current study had an adequate level of knowledge regarding breast reconstruction. Among the participants, 62.1% had a positive perception of breast reconstruction.
Conclusion:
This study underscores the significance of improving access to breast reconstruction in Saudi Arabia by addressing surgeon-related factors, such as insufficient expertise and negative attitudes. Efforts should be made to enhance the referral process for breast reconstruction, increase healthcare providers\' awareness about the benefits of breast reconstruction, and address negative opinions among healthcare professionals.

Background: Background: There has been a growing interest in determining those risk factors associated with adverse outcomes in early stages of lower gastrointestinal bleeding (LGIB). Objective: The aim of our study was to analyze the risk factors associated with severe bleeding, emergency surgery and in-hospital mortality. Material and methods: We conducted an observational and retrospective study on 1850 patients consecutive managed between January 1999 and December 2018 for LGIB. We analyzed thirteen variables within the first four hours of hospitalization to evaluate risk severity. Diverticular disease was considered to determine factors associated with emergency surgery, and the preoperative American Society of Anesthesiologists (ASA) score was used to assess mortality and emergency surgery. Results: Out of 1850 cases, 194 were severe and 1656 were mild/moderate, Patients > 70 years, with HR > 120 beats/min, BP < 90 mm Hg, oliguria, massive hematochezia, hematocrit < 30%, hemoglobin < 7 g% and need for transfusions presented statistically significant associations with severe bleeding. Age > 70 years, anticoagulation, hypotension, tachycardia, hemoglobin < 7 g%, oliguria, need for transfusion and massive hematochezia were significant predictors of emergency surgery. A prognostic formula was constructed to predict the need for surgery (sensitivity 94%, specificity 74%, positive predictive value 91% and negative predictive value 81%). AUC-ROC: 0,89%. Age > 70 years, anticoagulation, massive hematochezia transfusions and emergency surgery were identified as predictors of mortality. Fifteen of the sixteen patients who underwent surgery and died had ASA ≥ grade 4. Conclusions: The variables analyzed are simple, reliable and statistically significant to estimate the risk of severe bleeding, need for emergency surgery and mortality.
Mixed circumferential hemorrhoidal prolapse. Combined treatment with mechanical stapler and laser coagulation
Authors: Piccinini Pablo , Avellaneda Nicolás , Carrie Augusto , Serrano María Eva
Published: December 2023

Management of circumferential hemorrhoidal prolapse represents a challenge for surgeons. There are currently many alternatives to conventional procedures.; however, none of these techniques consider treatment of external disease. Even procedures associated with less postoperative pain as stapled hemorrhoidectomy or Doppler-guided hemorrhoidal artery ligation do not involve treatment of the external component. The aim of this publication is to present the technique detailed to treat patients with mixed hemorrhoidal prolapse, combining stapled hemorrhoidopexy with laser coagulation of external hemorrhoids. The results have been previously documented in a total of 25 patients, with 4% of complications. We conclude that the procedure is an option to consider in patients with circumferential hemorrhoidal prolapse with external component.
“Never Event” in surgery: Root-Cause Analysis
Authors:   Hospital Universitario Austral. Buenos Aires. Argentina., Chwat Carina , Seisdedos Mariana , Lemme Gustavo , Iudica Fernando , Cingolani Pablo
Published: December 2023

At least half of the adverse events on hospitalized patients are associated with surgery. Root cause analysis (RCA) is a systematic way of analyzing these events to find their causes through a step-by-step review of the chronology of facts, identifying those that could have caused the event. An Ishikawa diagram (also called fishbone diagram) is a visual method for root cause analysis that allows the identification and categorization of all possible causes of an event. The goal is to answer what happened, why did it happen, and what can be done to prevent it from happening again. The ultimate goal is to improve healthcare processes by preventing the recurrence of the adverse event and prioritizing learning and improvement based on its analysis. Communicating the findings of the analysis and the measures to be implemented, discussing cases in morbidity and mortality meetings and continuous education of staff are the cornerstones for changing the culture towards one centered on safety and quality, replacing the “reactive” culture with a “proactive” culture, which considers events as an instrument for learning and continuous improvement.

Objectives: Identify associated factors with emergence delirium in children in the Post-Anesthetic Recovery Unit of a Pediatric Health Specialized Institute in Peru. Methods: A cross-sectional study was carried out in children from 2 to 6 years old, physical status classification I and II, in elective procedures under anesthesia. The main variable was the presence of emergence delirium evaluated with the Pediatric Anesthesia Emergence Delirium scale greater than or equal to 10 points. To identify the factors associated with delirium, the Poisson regression model was applied and a p value < 0.05 was considered significant. Results: Of the 150 children, it was found that the incidence of emergence delirium occurred in 10.6%. Of these, 81.4% were under 5 years of age, pain was significantly associated in 37.5% with PR = 3.63, 95%CI [1.20, 10.1] and it was observed that 68, 8% required palliative care. Conclusions: Pain was associated with delirium of postanesthetic emergence in children. Prevention and treatment of emergence delirium should focus on postoperative pain control and careful monitoring of patients after surgery.
