Delirium is common in hospitalised patients, and there is currently no specific treatment. Identifying and treating underlying somatic causes of delirium is the first priority once delirium is diagnosed. Several international guidelines provide clinicians with an evidence-based approach to screening, diagnosis and symptomatic treatment. However, current guidelines do not offer a structured approach to identification of underlying causes. A panel of 37 internationally recognised delirium experts from diverse medical backgrounds worked together in a modified Delphi approach via an online platform. Consensus was reached after five voting rounds. The final product of this project is a set of three delirium management algorithms (the Delirium Delphi Algorithms), one for ward patients, one for patients after cardiac surgery and one for patients in the intensive care unit.
Exploring Standard and Alternative Sites for Left Ventricular Assist Device Inflow Cannula and Outflow Graft Placement
Authors: Dimitrov Kamen , Zimpfer Daniel 
Published: January 2024

Left ventricular assist device (LVAD) therapy is an essential tool in the armamentarium for managing refractory heart failure. The traditional LVAD placement involves insertion of the inflow cannula (IC) at the left ventricle’s true apex and attachment of the outflow graft (OG) to the ascending aorta (AA), which ensures alignment with physiological blood flow and minimizes complications. However, patient-specific anatomical variations and prior medical interventions necessitate considering alternative IC and OG placement techniques. This chapter reviews the standard and alternative IC and OG placement sites and emphasizes the importance of adapting LVAD component placement to individual patient needs, highlighting the potential of alternative techniques in improving outcomes. Despite the predominance of standard sites due to their proven efficacy, the heterogeneity of patient conditions underscores the need for flexible, patient-tailored approaches.

Published: January 2024

Pengolahan karet di Kalimantan Barat pada umumnya menjadi lump dan slab dengan menggunakan koagulan asam formiat. Harga asam formiat yang mahal, tidak ramah lingkungan serta berbahaya terhadap kesehatan membuka peluang pengembangan penggumpal alternatif bersifat alami. Penelitian ini menggunakan bahan penggumpal alami berupa jeruk sambal, buah mengkudu, serta buah asam maram. Kandungan asam organik pada masing-masing buah tersebut dapat menurunkan pH lateks mencapai pH isoelektrik sehingga dapat membantu lateks untuk menggumpal. Tujuan penelitian adalah untuk mengetahui pengaruh penggumpal alami terhadap kualitas slab selama penyimpanan. Pengolahan karet dilakukan di kebun karet Dusun Sungai Pelanduk, Kabupaten Sanggau dan analisis kimia dilaksanakan di Laboratorium Kimia Program Studi Pengelolaan Hasil Perkebunan (PHP) Politeknik Negeri Pontianak PSDKU di Kabupaten Sanggau.
Hasil pengamatan memperlihatkan pH ekstrak jeruk sambal, ekstrak asam maram ekstrak mengkudu terfermentasi (secara berturut-turut) sebesar 1.8, 2.2 dan 3.4. Semakin tinggi konsentrasi yang ditambahkan akan mempercepat proses koagulasi lateks. Waktu penggumpalan paling cepat adalah penambahan ekstrak jeruk sambal konsentrasi 20 dan 30% (secara berturut turut) yaitu selama 11 dan 9 menit. Tidak terlihat adanya pengaruh yang nyata akibat dari perlakuan terhadap kadar zat menguap dan kadar abu slab yang dihasilkan. Nilai PRI slab berkisar antara 65,768% hingga 73,214 %. Nilai PRI tersebut telah memenuhi persyaratan mutu SNI SIR 10 dan SIR 20 yaitu minimal 50% dan 60%.
A categorização da Educação Ambiental e de conceitos e atitudes sustentáveis por grupos universitários em diferentes fases de formação

Published: January 2024

Esta pesquisa teve por objetivo investigar a percepção de Educação Ambiental (EA) dos acadêmicos do curso de graduação em Ciências da Natureza e de Especialização em Educação Ambiental da Universidade Federal do Pampa, bem como identificar a compreensão destes acerca da geração de resíduos no seu cotidiano, considerando que a EA pode contribuir para a consolidação teórico-metodológica do campus como espaço privilegiado para a produção de conhecimento, discussões e reflexões socioambientais relevantes. O estudo, de natureza quali-quantitativa, é parte de uma pesquisa e teve como instrumento de coleta de dados questionário semiestruturado. A questão aberta sobre concepções de EA foi categorizada através da Análise Textual Discursiva (ATD); para a questão sobre conhecimento da Reciclagem foi criada uma categorização, segundo conceitos de autores e legislação vigente. As demais questões foram analisadas a partir da metodologia de contagem de eventos. Os resultados revelam que a ATD permitiu analisar o todo em partes, percebendo-se a impossibilidade de classificar o pensamento do indivíduo em categoria única. A maioria dos registros identificam-se com a categoria Naturalista, tanto dos ingressantes (41%), finalistas (30%) quanto pós-graduandos (49%), demonstrando uma percepção todavia conservadora. Apesar disso, entendemos a categorização não como para dividir ou rotular pensamentos que diferem devido às formações e visões, e sim, analisar suas características para aperfeiçoá-las. Sobre as atitudes sustentáveis no cotidiano, a maioria menciona conhecimento sobre coleta seletiva, compostagem e reciclagem, mas parte considerável não pratica estas atividades.

Published: January 2024

Cardiovascular illness is becoming more commonplace every day, which makes early identification of the condition worrisome and essential. Making a cardiac diagnosis is a challenging procedure that has to be finished fast and expertly. The identification and prediction of cardiovascular illness are vital medical responsibilities that help cardiologists appropriately diagnose and treat their patients. Deep Learning (DL) algorithms have found increasing usage in the medical industry because of their ability to recognize patterns in data. By applying machine learning to categorize the occurrence of cardiovascular illness, clinicians can reduce the rate of misdiagnosis. The goal of this work is to develop an ML model for cardiovascular disease (CVD) forecast based on correlated problems. This research develops a model that can accurately anticipate CVD illnesses, which will reduce the fatality rate from these ailments. This work employs a variety DL approaches to compare the results and analysis of the UCI Machine Learning Heart Disease dataset. We used a benchmark dataset of UCI Heart disease prediction for this work, which consists of 14 different heart disease-related parameters. As DL models, there are Convolutional Nueral Network (CNN), Artificial Neural Network (ANN) and Long Short-Term Memory (LSTM). When compared to DL techniques, the result shows that LSTM offers superior prediction accuracy in less time. 91% accuracy was attained using this LSTM technique. This model performs better on training and testing data. The models were fitted to the test dataset as well as trained on the training dataset to see which fared best. The matrices acquired during this process were accuracy, specificity, sensitivity, Area Under Curve (AUC) and the Receiver Operating Characteristic Curve (ROC).

Published: January 2024

Let G be connected graph. A dominating set D in G is said to be a leaf dominating set if <D> must have at least one leaf vertex. The minimum cardinality of a leaf dominating set is said to be the leaf domination number, denoted by Yld (G). Any minimal dominating set with minimum cardinality is called the Yld set. In this paper, we determine the leaf domination number and calculate the leaf domination number for standard graphs.
The Moderating Role of Perceived Efficacy of COVID-19 Prevention Measures on the Relation Between Perceived Risk and Perceived Mental Health

Published: January 2024

The pandemic situation caused by COVID-19 led countries to adopt harsh and prolonged (over time) measures that—along with the high number of infections and deaths and continuous negative information—have affected the mental health of individuals. In this study, the impact on mental health of the COVID-19 health crisis in Spain was explored through the perceived efficacy of pandemic containment measures as a moderator of the relationship that COVID-19 perceived risk establishes with stress and depression. A questionnaire composed of scales conceived to measure COVID-19 perceived risk, perceived efficacy of COVID-19 prevention measures, stress, and depression was completed by 478 adults living in Spain (66.9% females, Mage = 36.30, SD = 15.32) between May 16, 2021, and June 6, 2021. The results confirmed the moderating role of perceived efficacy. Perceived efficacy acted as a protective factor for stress and depression by decreasing the negative impact that perceived risk had on both variables related to mental distress. Also, the perception that participants had about the effectiveness of prevention measures appeared to be a relevant protective factor regarding mental health during the pandemic. This study highlights the relevance of psychological interventions and government policies that improve positive risk communication and provide adequate information regarding the effectiveness of health-prevention measures.
La pandemia del COVID-19 ha llevado a los países a adoptar severas y prolongadas medidas que —junto con el alto número de contagios y muertes y la continua información negativa— ha afectado la salud mental de las personas. Este estudio analiza el impacto de la crisis sanitaria del COVID-19 en España explorando el rol moderador de la eficacia percibida de las medidas de contención en la relación que establece la percepción del riesgo del COVID-19 con el estrés y la depresión. Un total de 478 adultos residentes en España (un 66.9% mujeres; Medad = 36.30, DT = 15.32) completaron un cuestionario con escalas concebidas para medir el riesgo percibido del COVID-19, la eficacia percibida de las medidas de protección, el estrés y la depresión entre el 16 de mayo y el 6 de junio de 2021. Los resultados confirmaron el rol moderador de la eficacia percibida, la cual actuó como un factor protector del estrés y la depresión al disminuir el impacto negativo que la percepción de riesgo del COVID-19 tiene en ambas variables relacionadas con el distrés mental. La percepción que tienen los individuos sobre la efectividad de las medidas de protección parece ser un factor protector relevante en relación con la salud mental durante una pandemia. Se subraya la relevancia de intervenciones psicológicas y de políticas gubernamentales que mejoren la comunicación positiva del riesgo y la información adecuada sobre la eficacia de las medidas de protección.
Authenticity Scale: Validity and Reliability Evidence in a Sample from Brazil and Portugal
Authors: Coscioni Vinicius , Pereira Teixeira Marco Antônio , Paixão Maria Paula 
Published: January 2024

This study introduces distinct types of validity and reliability evidence of the Authenticity Scale (AS) in a sample from Brazil and Portugal. It consists of an online survey with 1,077 Brazilian citizens and 622 Portuguese citizens. The study tested the model with three correlated factors (self-alienation, authentic living, and accepting external influence), the unidimensional model, and the bi-factor model. The model with three correlated factors was retained, with the three subscales demonstrating moderate to good reliability. Multigroup confirmatory factor analysis suggested scalar invariance across culture, gender, age, education, occupation, and Covid-related concern and impact. The items were assessed by graded response model (GRM), which suggested that the three subscales are not able to distinguish respondents with high authenticity traits. GRM and descriptive statistics indicated that the rating-scale is inappropriate, particularly for authentic living subscale, which is affected by ceiling effect. Associations with presence of meaning showed additional validity evidence. Despite the limitations, the AS is an effective measure to assess authenticity across different groups. Potential modifications for the improvement of the AS are discussed.
Este estudio presenta distintos tipos de evidencias de validez y confiabilidad de la Escala de Autenticidad (AS) en una muestra de Brasil y Portugal. El estudio consiste en una encuesta con 1.077 brasileños y 622 portugueses. Se testó el modelo con tres factores correlacionados (autoalienación, vivir auténtico y aceptación de la influencia externa), el modelo unidimensional y el modelo bifactorial. Se retuvo el modelo con tres factores correlacionados, con las tres subescalas alcanzando confiabilidad moderada a buena. Análisis factorial confirmatorio multigrupo sugirió invariancia escalar para cultura, género, edad, educación, ocupación y preocupación e impacto relacionados con Covid. Los ítems fueron evaluados por graded response model (GRM), sugiriendo que las tres subescalas no discriminan las personas con altos rasgos de autenticidad. GRM y estadísticas descriptivas indican que la escala de puntuación es inapropiada, particularmente para la subescala vivir auténtico, que es afectada por efecto techo. Las asociaciones con presencia de sentido mostraron evidencia adicional de validez. A pesar de las limitaciones, la AS es una medida adecuada para evaluar la autenticidad en diferentes grupos. Se discuten posibles modificaciones para el aprimoramiento de la AS.
Sociología relacional de la xenofobia. El caso del rechazo a la inmigración venezolana en Lima, 2019
Authors: Gauna Peralta Aníbal 
Published: January 2024

The objective of this article is to propose an explanatory model of the different levels of rejection of (Venezuelans) immigrants, through thirteen mixed interviews carried out in the city of Lima between the end of 2019 and the beginning of 2020. Based on a relational model, it is concluded that, regardless of the direct impact of immigration on the macroeconomy, or the relative levels of crime: (1) there are different levels of generalization of negative images regarding immigrants (total generalization, intermediate and non-xenophobic generalizations), measured based on the answer to the question of “who should be deported?” (2) Combinations of transactional sources of influence, organized as ‘social structures of experience’, largely explain the variations in the generalization of negative images about immigrants. As a result of an analytical projection of these findings and of previous studies, it is hypothetically proposed that (3) the enormous and sudden migratory volume creates a relational context that favors the generalization of negative images and possibly a reactive ethnicity among immigrants. These results would help to explain the high levels of rejection of Venezuelan forced immigration in Lima, Peru.
El objetivo de este artículo es proponer un modelo explicativo de los diferentes niveles del rechazo a los inmigrantes (venezolanos), a través de trece entrevistas mixtas realizadas en la ciudad de Lima entre finales de 2019 y principios de 2020. Sobre la base de un modelo relacional, se concluye que, independientemente al impacto directo de la inmigración en la macroeconomía, o a los niveles relativos de delincuencia: (1) existen diferentes niveles de generalización de imágenes negativas respecto a los inmigrantes (generalización total, generalizaciones intermedias y no-xenofóbicas), medidos sobre la base de la respuesta de “¿a quiénes se debe deportar?” (2) Combinaciones de fuentes transaccionales de influencia, organizadas como ‘estructuras sociales de la experiencia’, explican ampliamente las variaciones en la generalización de imágenes negativas sobre los inmigrantes. Como resultado de una proyección analítica de estos resultados y de estudios previos, se propone hipotéticamente que (3) el enorme y súbito volumen migratorio crea un contexto relacional que favorece la generalización de imágenes negativas y posiblemente una etnicidad reactiva entre los inmigrantes. Estos resultados contribuirían a explicar los elevados niveles de rechazo a la inmigración forzada venezolana en Lima, Perú.
