Published: June 2023

University students are experiencing a mental health crisis across the world. COVID-19 has exacerbated this situation. We have conducted a survey among university students in two universities in Lebanon to gauge mental health challenges experienced by students. We constructed a machine learning approach to predict anxiety symptoms among the sample of 329 respondents based on student survey items including demographics and self-rated health. Five algorithms including logistic regression, multi-layer perceptron (MLP) neural network, support vector machine (SVM), random forest (RF) and XGBoost were used to predict anxiety. Multi-Layer Perceptron (MLP) provided the highest performing model AUC score (AUC=80.70%) and self-rated health was found to be the top ranked feature to predict anxiety. Future work will focus on using data augmentation approaches and extending to multi-class anxiety predictions. Multidisciplinary research is crucial in this emerging field.

Published: June 2023

Current challenges of rare diseases need to involve patients, physicians, and the research community to generate new insights on comprehensive patient cohorts. Interestingly, the integration of patient context has been insufficiently considered, but might tremendously improve the accuracy of predictive models for individual patients. Here, we conceptualized an extension of the European Platform for Rare Disease Registration data model with contextual factors. This extended model can serve as an enhanced baseline and is well-suited for analyses using artificial intelligence models for improved predictions. The study is an initial result that will develop context-sensitive common data models for genetic rare diseases.

The real-time revolutions per minute (RPM) data, ECG signal, pulse rate, and oxygen saturation levels were collected during 16-minute cycling exercises. In parallel, ratings of perceived exertion (RPE) were collected each minute from the study participants. A 2-minute moving window, with one minute shift, was applied to each 16-minute exercise session to divide it into a total of fifteen 2-minute windows. Based on the self-reported RPE, each exercise window was labeled as “high exertion” or “low exertion” classes. The heart rate variability (HRV) characteristics in time and frequency domains were extracted from the collected ECG signals for each window. In addition, collected oxygen saturation levels, pulse rate, and RPMs were averaged for each window. The best predictive features were then selected using the minimum redundancy maximum relevance (mRMR) algorithm. Top selected features were then used to assess the accuracy of five ML classifiers to predict the level of exertion. The Naïve Bayes model demonstrated the best performance with an accuracy of 80% and an F1 score of 79%.

Published: June 2023

The purpose of this mapping review was to examine the Recommendations of the Medical Informatics Association (IMIA) on Education in Biomedical and Health Informatics (BMHI) in relation to the contents of the Nurses’ Competency Scale (NCS). The BMHI domains were mapped to the NCS categories to find analogous competence areas. As a conclusion, a consensus is presented on what each of the BMHI domain could mean on a responding NCS category. The number of the relevant BMHI domains were two for the Helping role, the Teaching and coaching, the Diagnostics functions, the Therapeutic interventions, and the Ensuring quality domains. The number of the relevant BMHI domains was four for the Managing situations and the Work role domains, of the NCS. The essence of nursing care has not changed, however, current means and equipment in practice require updated knowledge and digital skills for nurses. Nurses have a special role in narrowing the view gap between the views related to clinical nursing and informatics practice. Documentation, data analyses, and knowledge management are essential parts in nurses’ competence today.

Published: June 2023

BACKGROUND: At present, there is no consensus on the required duration of neoadjuvant endocrine therapy (NET), yet there is no consistent conclusion on the factors influencing the efficacy of treatment with breast cancer after prolonged treatment. OBJECTIVE: To explore the effect of prolonged NET on the efficacy of patients with breast cancer and analyze the factors influencing the efficacy of treatment with breast cancer after the treatment duration is prolonged. METHODS: The case histories of 51 patients who were diagnosed with breast cancer and received NET in our hospital from September 2017 to December 2021 were retrospectively analyzed. All patients received NET for over 12 months. The clinical efficacy and tumor size changes after treatment for six months and 12 months were compared, and the factors influencing the efficacy of treatment with breast cancer after patients’ treatment duration was prolonged were analyzed. RESULTS: (1) Among the 51 patients, the objective remission rate (ORR) of NET, at T = 6 months was 21.6%, and the average tumor size was 15.52 ± 7.30 mm. The ORR of the NET at T = 12 months was 52.9%, and the average tumor size was 13.79 ± 7.43 mm. (2) After the treatment duration was prolonged, the clinical ORRs of patients with estrogen receptor (ER) (+) and progesterone receptor (PR) (+) were significantly higher than that of patients with ER (+) and PR (-) and patients with ER (-) and PR (+), which was (P < 0.05). (3) There was no significant difference between the patients’ axillary lymph node status and the Ki67 expression before treatment and the clinical ORR after prolonged treatment, which was (P> 0.05). CONCLUSIONS: (1) Prolonging the NET duration for patients with breast cancer can improve their clinical ORR and further reduce the tumor size, but patients’ conditions should be closely monitored during the treatment process to prevent the progression of disease due to drug resistance. (2) The expression state of ER or PR may be used as a factor influencing the efficacy of treatment with breast cancer after prolonged treatment. (3) There was no significant effect on the patients’ axillary lymph node status and the Ki67 expression before treatment on the clinical efficacy after prolonged treatment.

Published: June 2023

BACKGROUND: Surgery is the preferred treatment for rectal cancer, but surgical treatment alone sometimes does not achieve satisfactory results. OBJECTIVE: To explore the value of multimodal Magnetic Resonance (MR) images in evaluating T staging of rectal cancer after neoadjuvant therapy and to compare and analyze with pathological results. METHODS: This study retrospectively analyzed 232 patients with stage T3, T4 rectal cancer between January 1, 2017 and October 31, 2022. MR examination was performed within 3 days before surgery. Different MR sequences were used for mrT staging of rectal cancer after neoadjuvant therapy and compared with pathological pT staging. The accuracy of different MR sequences in evaluating T staging of rectal cancer was calculated, and the consistency between the two was analyzed by kappa test. The sensitivity, specificity, negative predictive value and positive predictive value of different MR sequences in evaluating rectal cancer invading mesorectal fascia after neoadjuvant therapy were calculated. RESULTS: A total of 232 patients with rectal cancer were included in the study. The accuracy of high-resolution T2 WI in evaluating T staging of rectal cancer after neoadjuvant therapy was 49.57%, and the Kappa value was 0.261. The accuracy of high-resolution T2WI combined with diffusion weighted imaging (DWI) in evaluating T staging of rectal cancer after neoadjuvant therapy was 61.64%, and the Kappa value was 0.411. The accuracy of high-resolution combined with DCE-MR images in evaluating T staging of rectal cancer after neoadjuvant therapy was 80.60%, and the Kappa value was 0.706. The sensitivity and specificity of high-resolution t2-weighted imaging (HR-T2WI) combined with dynamic contrast-enhancement magnetic resonance (DCE-MR) in evaluating the invasion of mesorectal fascia were 83.46% and 95.33%, respectively. CONCLUSION: Compared with HR-T2WI combined with DWI images for mrT staging of rectal cancer after neoadjuvant chemoradiotherapy (N-CRT), HR-T2WI combined with DCE-M has the highest accuracy in evaluating mrT staging of rectal cancer after neoadjuvant therapy (80.60%), and has a high consistency with pathological pT staging. It is the best sequence for T staging of rectal cancer after neoadjuvant therapy. At the same time, the sequence has high sensitivity and specificity in evaluating mesorectal fascia invasion, which can provide accurate perioperative information for the formulation of surgical plan.

Screening approaches for lung cancer by blood-based biomarkers: Challenges and opportunities
Authors: van den Broek Daniel , Groen Harry J.M.
Published: June 2023

Lung cancer (LC) is one of the leading causes for cancer-related deaths in the world, accounting for 28% of all cancer deaths in Europe. Screening for lung cancer can enable earlier detection of LC and reduce lung cancer mortality as was demonstrated in several large image-based screening studies such as the NELSON and the NLST. Based on these studies, screening is recommended in the US and in the UK a targeted lung health check program was initiated. In Europe lung cancer screening (LCS) has not been implemented due to limited data on cost-effectiveness in the different health care systems and questions on for example the selection of high-risk individuals, adherence to screening, management of indeterminate nodules, and risk of overdiagnosis. Liquid biomarkers are considered to have a high potential to address these questions by supporting pre- and post- Low Dose CT (LDCT) risk-assessment thereby improving the overall efficacy of LCS. A wide variety of biomarkers, including cfDNA, miRNA, proteins and inflammatory markers have been studied in the context of LCS. Despite the available data, biomarkers are currently not implemented or evaluated in screening studies or screening programs. As a result, it remains an open question which biomarker will actually improve a LCS program and do this against acceptable costs. In this paper we discuss the current status of different promising biomarkers and the challenges and opportunities of blood-based biomarkers in the context of lung cancer screening.

Nowadays, the accumulated world experience of working in crisis situations shows that psychological assistance to patients experienced COVID-19 is provided mainly on a one-time basis — upon the fact of the incident, while the necessary subsequent psychological rehabilitation and preventive measures are not enough practiced. In most cases, the impact of a powerful stress factor is associated with an increase in the level of depression and anxiety, which can have a negative effect not only on the patient's life quality, but also on the prognosis, both short- term and long-term. The increased stress have an influence on the immunity decrease, which, in turn, reduces the threshold of resistance to infectious diseases, including COVID-19. In this regard, the WHO information note "Mental Health and Psychosocial Factors in the COVID-19 Outbreak", in addition to the appeal to the population during pandemic, contains recommendations for specialists providing various assistance types to preserve mental health and stabilize psychological state of the population. The presentation of current views on the problem of mental disorders during COVID-19 pandemic, both in patients and medical specialists, is the subject of this literature review.

An Analysis of the Continuum Hypothesis
Authors: Powell Andrew
Published: June 2023

This paper analyses the Continuum Hypothesis, that the cardinality of a set of real numbers is either finite, countably infinite or the same as the cardinality of the set of all real numbers. It argues that the Continuum Hypothesis makes sense as a very strong choice principle that is maximally efficient as a principle for deciding whether a real number is in a set of real numbers, in the sense that it is uniform in deciding membership for every real number in a countable number of steps. The approach taken is to analyze the intended meaning of the Continuum Hypothesis rather than to analyze models of set theory in which the Continuum Hypothesis is true or false and to use those models to support or reject the Continuum Hypothesis.

Authors: Vakulenko Olesya
Published: June 2023

The purpose of the article is to identify trends in the disclosure of the plot-content aspect of a choreographic performance, built on the basis of or with the use of ballroom dance vocabulary, which is characteristic of the stage works of the XXI century. Research methodology. The method of artistic and stylistic analysis of expressive means of choreographic performance is applied; a typological method that helped to identify and consider the main methods of disclosing the plot-content aspect; the method of art history analysis, the application of which contributed to the consideration of compositional solutions of choreographic performances; the method of comparative analysis, which allowed to compare the techniques and methods of revealing the plot-content aspect of choreographic performances used by foreign and domestic directors at the present stage; method of theoretical generalization. Scientific novelty. Based on the art analysis of choreographic performances by European and domestic choreographers-producers A. Gades ("The Antonio Gades Compan"), F. Pinera and W. Villalba ("La Boca Tango Company"), A. Trunova (performance-performance "Bloody Wedding") ”) And N. Zhurenko (ballroom dance theater“ Fly Dance ”) revealed the tendencies of revealing the plot-content aspect of a choreographic performance, built on the basis of or with the involvement of ballroom dance vocabulary, characteristic of the modern stage of choreographic art development, and its figurative and conceptual content. Conclusions. The study showed that the modern practice of dance theaters is dominated by the tendency to use non-standard possibilities of artistic and figurative reflection of human existence, the author's approach to revealing the theme of stage choreographic work, innovative poetic and metaphorical images. Harmonious synthesis in the choreographic performance of the components of musical and choreographic imagery is positioned by modern producers as the main task in the process of revealing the content. Ballroom dance forms and dramatic moves correspond to the specific content and figurative series of stage work and the laws of reflection of reality in a choreographic performance are based on the degree of devotion to the metaphorical reflection of life.

Authors: Ilnitskya Оleksandra , Ilnitsky Vitaly
Published: June 2023

The purpose of the article is to identify the features of integration and methods of using digital technologies in modern practices using the example of innovative methods of stage lighting. The methodology is based on the complex methods of modern art criticism and is aimed at reviewing and theoretical understanding of the main aspects of using digital lighting technologies in modern stage art. The method of cultural-historical analysis (for studying trends in stage lighting technologies), the semiotic method (for studying and analyzing the symbolic content of lighting as a significant part of the spatial stage text), the typological method (for systematizing innovative principles and methods of lighting), and the method of figurative-stylistic analysis of works of contemporary stage art (dramatic and choreographic productions, performative installations). Scientific novelty. The features of integrating digital technologies into stage productions of the beginning of the 21st century using the specifics of the use of lighting are studied; the significance of stage lighting in the process of revealing the semantic-meaningful and artistic-figurative aspects of stage action is revealed and characterized; The specifics of lighting were identified and analyzed using the contemporary representations of drama theaters (Per Gunt, Hungarian State Theater Cluj-Napoca, director D. Zinder, 2008), choreographic productions (Political Mother choreographer-composer H. Schechter, 2010 ..) and performative installations ("Stifters Dinge"); prospects for the use of modern digital technologies in the context of the leading trends in the development of stage art of the 21st century are outlined. Conclusions. The use of modern digital technologies in stage art helps to expand the artist's capabilities by increasing the variety of expressive means. The directors, rethinking the meaning of lighting, offer the viewer only directed towards the idea of stage work, using means that affect the psychological state of a person; They strive to awaken emotions, memories, and thoughts corresponding to their own creative vision, generating complex visual experiences coexisting with the presented text. At the present stage of the development of stage art, due to the integration of digital technologies and the development of innovative methods and techniques, it is advisable to consider lighting as a productive component of the stage production, the functions of which go beyond the obvious or prosaic levels at which light only generates a shadow or color, focus or space, creating atmospheric, architectural and physical elements.

Forced Migration: The 1948 Palestinian Refugees
Authors: Almassri Juliana J. J.
Published: June 2023

During the 1948 Palestine war, more than 700,000 Palestinian Arabs fled or were expelled from their homes, accounting for roughly half of prewar Palestine’s Arab population. The exodus was a central component of the Palestinian society’s cracks, disempowerment and displacement, known as the Nakba, during which between 400 and 600 Palestinian villages were damaged and others were exposed to the Hebraization of Palestinian place names, and it also relates to the wider period of the conflict itself and the subsequent oppression up to the present day. The main aim of this research is to define the causes of the 1948 Palestinian exodus, which led to the creation of the Palestinian refugee problem. It also seeks to show the ways that the Nakba has influenced Palestinian history. This study explores the work of the United Nations Relief and Works Agency for Palestine Refugees in the Near East, a UN (United Nations) agency that supports Palestinian refugees’ relief and human development.

Objective: To study the effect of biostimulants on yield and its components in Azufrado Higuera beans in northern Sinaloa.
Design/Methodology/Approach: Randomized complete block design with three repetitions, a common bean variety, and five treatments (four biostimulants and one control). Assessed variables: plant height, yield, and its components.
Results: The seaweed-based (Ascophyllum nodosum and Macrocystis pyrifera) Fia Kelp® biostimulant caused a remarkable increase in plant height, seed yield, number of seeds per pod, and 100-seed weight.
Study Limitations/Implications: The study was carried out during a single crop cycle. Therefore, an ongoing assessment of the biostimulants used must be carried out during more consecutive cycles to prove their effect on the aerial biomass characteristics, harvest index, and number of pods per m2.
Findings/Conclusions: Foliar application of biostimulants had a positive effect on seed yield and some of its components with respect to the control. The number of normal pods per m2 was the variable with the highest correlation percentage regarding seed yield.
Trading off Time, Carbon, Active Travel, and Health: What do People Really Think about Traffic-reduction Measures?
Authors: Cohen Tom , Furlong Jamie , Farrow Lucy
Published: June 2023

An online survey polled a socio-demographically representative sample of approximately 2,000 UK residents concerning their attitudes to traffic restrictions that lead to longer car trips. Specifically, to what extent would respondents accept delays to everyday local car journeys if these were offset by reductions in NO2, greenhouse gas emissions or vehicular traffic, or by increases in active travel? Responses suggested high levels of acceptance of delay but this varied by nature of impact (less openness to increased active travel) and socio-demographic attribute (gender, educational attainment, car ownership, ethnicity, housing tenure, prior presence of local traffic restrictions). In particular, there were lower levels of delay acceptance amongst men, respondents without degree-level qualifications, and those in households with two or more cars. These findings are relevant to those communicating about traffic restrictions, in terms of which audiences they target and how they present impacts.

The government's policy of changing fuel prices is carried out every year. The public gave responses to this policy categorized as positive, negative, or neutral sentiments. The community's response was conveyed through tweets on the Twitter application. Based on the public's response to the policy, sentiment classification can be done using data mining classification techniques. Some research has been carried out on classification techniques using deep learning and machine learning methods. In general, deep learning methods get better results, and this research will be approached using the CNN method. The system stages start from crawling data, labeling, and preprocessing, which consists of cleaning, case folding, tokenization, normalization, removing stopwords and stemming, classification using CNN, and evaluation using 10-Cross Validation. The dataset used is 17.270. The results show that the developed classification system is relatively high, with the highest accuracy of 87%, 93% recall, 93% precision, and 90% F1 score. An in-depth analysis of the classification results and an understanding of sentiment toward rising fuel prices can also provide valuable insights.

A metallurgical furnace is needed in the metal forming process, a portable forging furnace is an installation tool specifically designed for metal heating, for the plastic deformation process in the forging process in the material technology laboratory. This heating furnace was made by Feriadi Sidik with an initial opening of 50 mm diameter, only capable of reaching a temperature of 3000C with a hole position of 15:85 cm. the inability of this furnace to reach temperatures greater than 10000C which causes the practicum process to be hampered, therefore modifications were made by widening the combustion opening from 50 mm to 100 mm. Enlargement of these openings results in a change in compressor pressure which results in a change in the air flow rate so that the temperature propagates up. The increase in temperature is measured from changes in the compressor speed and the resulting temperature at the initial pressure (P= 17.2km/h, T= 309.20C), and the final pressure (P=23.2km/h, T= 14320C), with testing time for from 30 seconds to 300 seconds. From the modification results, it is proven that by increasing the opening of the combustion hole, it can produce a change in the temperature rate. This modified furnace can be used to heat low carbon steel and high carbon steel for the forging process. Keywords: Furnace, Modification, Forging, Temperature, openings
