Obesity rates have increased, and so has the need for more specific treatments. This trend has raised interest in non-surgical weight loss techniques that are novel, safe, and straightforward. Thus, the present review describes the endoscopic bariatric treatment for obesity, its most recent supporting data, the questions it raises, and its future directions. Various endoscopic bariatric therapies for weight reduction, such as intragastric balloons (IGBs), aspiration therapy (AT), small bowel endoscopy, endoscopic sleeve gastroplasty, endoluminal procedures, malabsorption endoscopic procedures, and methods of regulating gastric emptying, were explored through literature sourced from different databases. IGBs, AT, and small bowel endoscopy have short-term effects with a possibility of weight regain. Minor adverse events have occurred; however, all procedures reduce weight. Vomiting and nausea are common side effects, although serious complications have also been observed.

Properties of Mixing SAC Solder Alloys with Bismuth-Containing Solder Alloys for a Low Reflow Temperature Process
Authors: Swanson Tayler J. , Anselm Martin K.
Published: October 2023

The subject of extensive research has been the establishing of lower temperature soldering of electronic assemblies that are similar to the once common yet still preferred eutectic Tin-Lead (SnPb) soldering processes that are below 217˚C. This research measured and compared the mixing mechanisms of paste and ball dissolution. Mixed soldered assemblies will have different dissolution results that are dependent on the peak reflow temperature. The hypothesis for this experiment was to determine the relationship of various times above the melting point of low temperature solders containing Bismuth. The results measured are from solder joints of both SAC305 and Bismuth containing solders formed at lower process temperatures compared to the standard high temperatures which peak at 230˚C-260˚C. The Bismuth containing solders evaluated start with the highest to lowest weight percentage of Bismuth, the eutectic 58Bismuth/42Tin (58Bi/42Sn), 57Bi/42Sn/1Ag and a propriety alloy that has a lower Bismuth content along with various micro alloys, defined as 40-58Bi/Sn/X (X representing proprietary micro alloys or doping). The assembly was with an 18mil 96.5Tin/3.0Silver/0.5Copper (SAC305) solder ball mixed with each solder paste. These solder alloys were exposed to three different peak temperatures 180˚C, 195˚C, 205˚C. Another reflow profile attribute of focus was times above 138˚C - the melting point of the eutectic Sn58Bi alloy, this term used throughout the study is referred to Time Above Melting (TAM).  The ball and paste assembly used the times above melting of 120sec and 240sec to represent process extremes and verify their significance on improving mixing level results. The average mixing % levels were recorded and compared for each solder joint combination to test the theory that the solder paste solidifies during the time above melting (TAM) within the reflow oven. [1] This experiment effectively demonstrates that the reflow profile parameter for time above melting has limited effectiveness in additionally mixing the paste with the BGA solder ball.  Optimization of mixing percentages will need to be achieved by optimizing the paste and ball volumes.

Devido à produção de bovinos no Brasil ser desenvolvida principalmente a pasto, a melhoria das pastagens é considerada de suma importância. Umas das formas de tornar essas áreas mais produtivas é um adequado fornecimento de nutrientes, que pode ser feito com adubos orgânicos. Dessa forma objetivou-se com este trabalho abordar sobre o uso e eficiência de adubos orgânicos na produção de forrageiras. As forrageiras respondem bem as adubações, principalmente nitrogenada e fosfatada, com expressivos aumentos de produtividade, porém os custos com esses adubos são considerados altos dentro do sistema produtivo. Dessa forma o uso de material orgânico se torna interessante, com destaque para a cama de frango, que tem proporcionado resultados semelhantes ou mesmo superior à adubação inorgânica, até mesmo para as forrageiras mais exigentes. Para atender aos critérios ambientais deve-se atentar ao nutriente considerado crítico, e as doses, que quando em excesso podem causar poluição. A cama de frango é uma opção para a adubação de pastagens, podendo substituir parcialmente ou totalmente a adubação inorgânica.
In-disciplinas del dibujo

¿Qué es dibujo? Asumir esta pregunta es la responsabilidad fundamental del dibujante. El dibujo dejó su condición de medio para otro fin-, (de ser boceto, obra menor, de tener un rol secundario), y se convirtió en fin en sí mismo, en protagonista,. Esto ocurrio desde el momento en que los dibujantes se empezaron a preguntar sobre el dibujo: ¿si el dibujo no es medio, entonces qué es?, ¿qué y cómo podemos aprender del dibujo?, ¿de qué hablamos cuando nos referimos al dibujo?, ¿qué podría llegar a ser el dibujo fenomenológica, ontológica, epistemológica y metodológicamente? Tal vez hay algo que nos puede llegar a diferenciar de la modernidad, por lo menos en el área del arte, y es que sabemos muy bien que tratar de definir un concepto puede conducirnos a agotar sus posibilidades, a agotar el término. Precisamente, de esto es que va el dibujo expandido, de deslindar los cercos de los conceptos propios del dibujo para poderlos repensar y ver qué podemos aprender de ello. Al hacer un paneo por el arte que se hace en la actualidad, y planteando un juego de insinuación maliciosa, podríamos llegar a señalar que es in-disciplinado. Como bien lo señala Gustavo Cabrera,: “En un contexto como es el del arte contemporáneo, cuyo rasgo más saliente es la inespecificidad disciplinar, donde la hibridación -consecuencia de la erosión de las fronteras entre campos del saber y del hacer- ha configurado manifestaciones artísticas inclasificables”.1 Esa inespecificidad disciplinar y la erosión de las fronteras entre los campos del saber, son precisamente lo que caracteriza a las in-disciplinas del arte actual y, por ende, del dibujo expandido. Esta exposición es el vivo reflejo de esas in-disciplinas. Las virutas de un lápiz cayendo, los vestigios que deja el cuerpo y la pintura, una línea hecha con fotografías, fragmentos de ropa abultada y las posproducciones referenciales a la historia del arte, dejan en claro que no se trata de algo tan estrecho como delimitar formas con los trazos de un lápiz;, es algo mucho más difícil, se trata de dibujar líneas de pensamiento artístico complejo.

The study aimed to examine the relationship between the psychological resilience levels of taekwondo players and their state and trait anxiety levels.Taekwondo is a martial art originating from the Far East. Taekwondo is a very popular sport in our country because it is an Olympic sport. In the literature, the contribution of Taekwondo sport to both physical and mental development is expressed. Normally, 3 rounds are played over 2 minutes, and the competition may conclude at the end of the 2nd round, provided that the athletes close the rounds with a 2-0 advantage. Athletes play an average of 6-8 competitions a day and experience a high physical and mental process until the end of the day. It is thought that the competition process may cause some psychological processes in athletes. In this process; Athletes are expected to experience some psychological processes such as anxiety, worry, fear and stress. The universe of the study consisted of 270 taekwondo athletes participating in the U-21 Taekwondo Turkey Championship. While 130 of the participants were male athletes, the remaining 140 were female participants. While 72 participants were national athletes, the age range of the total participants was found to be 16-20. The data were collected from the athletes through a questionnaire during the Turkish Taekwondo Championships. The athletes were informed before the weigh-in and they were asked to fill in the questionnaires on a voluntary basis. The completed questionnaires were collected from the athletes and stored. The socio-demographic information form for the demographic information of the athletes, the Brief Psychological Resilience Scale, and the STAI-I and STAI-II Anxiety Scales (Stated and Continuous) were used to collect the data. The analyses done in line with the options specified by the athletes were made in the SPSS 23.0 program. After the reverse items of the scales were translated, the scores obtained from the scales were summed. Then, the data were evaluated with Kolmogorov Smirnov analysis of normality. According to the results of the normality test, it was determined that the data showed normality. According to the demographic variables of the athletes, t-test was used in independent groups for paired groups and Tukey-corrected One Way Anova test was used for groups of more than two. Pearson correlation analysis was used to evaluate the relationship between the self-esteem mean score and the resilience scale mean score. The results were evaluated at the p
Toward a Physical Understanding of Galaxy–Halo Alignment

Published: October 2023

We investigate the alignment of galaxy and halo orientations using the TNG300-1 hydrodynamical simulation. Our analysis reveals that the distribution of the 2D misalignment angle θ
2D can be well described by a truncated shifted exponential distribution with only one free parameter across different redshifts and galaxy/halo properties. We demonstrate that the galaxy–ellipticity (GI) correlations of galaxies can be reproduced by perturbing halo orientations with the obtained θ
2D distribution, with only a small bias (<3°) possibly arising from unaccounted for couplings between θ
2D and other factors. We find that both the 2D and 3D misalignment angles θ
2D and θ
3D decrease with ex situ stellar mass fraction F
acc, halo mass M
vir, and stellar mass M
*, while increasing with the disk-to-total stellar mass fraction F
disk and redshift. These dependences are in good agreement with our recent observational study based on BOSS galaxy samples. Our results suggest that F
acc is a key factor in determining galaxy–halo alignment. Grouping galaxies by F
acc nearly eliminates the dependence of θ
3D on M
vir for all three principle axes, and also reduces the redshift dependence. For θ
2D, we find a more significant redshift dependence than for θ
3D even after controlling F
acc, which may be attributed to the evolution of galaxy and halo shapes. Our findings present a valuable model for observational studies and enhance our understanding of galaxy–halo alignment.
Invalid lectotypification for Synodontis victoriae Boulenger, 1906 (Siluriformes, Mochokidae) by Poll (1971), and the designation of a new lectotype
Authors: Englmaier Gernot K. , Collins Rupert A.
Published: October 2023

The lectotype and paralectotype of Synodontis victoriae Boulenger, 1906, designated by Poll (1971), were examined. Inconsistencies between data presented for the designated lectotype and the illustrated individual raise the question of whether lectotypification by Poll is valid. This case is not formally regulated by the International Code of Zoological Nomenclature, but based on Article 74.5, the lectotypification for S. victoriae should be considered invalid because it cannot unambiguously indicate a single name-bearing specimen. Thus, we designate a new lectotype for S. victoriae (BMNH 1906.5.30.191, Entebbe, standard length 188.2 mm) out of two syntypes and provide illustrations and new morphometric and meristic data for both specimens.
Short-time free metaplectic transform: Its relation to short-time Fourier transform in $ L^2(\mathbb R^n) $ and uncertainty principles
Authors: Dar Aamir H. , Zayed Mohra , Bhat M. Younus
Published: October 2023

The free metaplectic transformation (FMT) has gained much popularity in recent times because of its various applications in signal processing, paraxial optical systems, digital algorithms, optical encryption and so on. However, the FMT is inadequate for localized analysis of non-transient signals, as such, it is imperative to introduce a unique localized transform coined as the short-time free metaplectic transform (ST-FMT). In this paper, we investigate the ST-FMT. First we propose the definition of the ST-FMT and provide the time-frequency analysis of the proposed transform in the FMT domain. Second we establish the relationship between the ST-FMT and short-time Fourier transform (STFT) in $ L^2(\mathbb R^n) $ and investigate the basic properties of the proposed transform including the reconstruction formula, Moyal's formula. The emergence of the ST-FMT definition and its properties broadens the development of time-frequency representation of higher-dimensional signals theory to a certain extent. We extend some different uncertainty principles (UPs) from quantum mechanics including Lieb's inequality, Pitt's inequality, Hausdorff-Young inequality, Heisenberg's UP, Hardy's UP, Beurling's UP, Logarithmic UP and Nazarov's UP. Finally, we give a numerical example and a possible applications of the proposed ST-FMT.
An alternative hyper-Poisson integer-valued GARCH model with application to polio, internet protocol and COVID-19 data
Authors: Fo Kee Wah , Ong Seng Huat , Ng Choung Min , Koh You Beng
Published: October 2023

Time series of counts are observed widely in actuarial science, finance, epidemiology and biology. These time series may exhibit over-, equi- and under-dispersion. The Poisson distribution is commonly used in count time series models, but it is restricted by the equality of mean and variance. Other distributions such as the generalized Poisson, double Poisson, hyper-Poisson, and COM-Poisson distributions have been proposed to replace the Poisson distribution to model the different levels of dispersion in time series of counts. These models have certain limitations such as complex expressions for the mean and variance which complicate the formulation as GARCH models. In this study, we propose an alternative hyper-Poisson (AHP) distribution, with simple forms of conditional mean and variance, for an integer-valued GARCH (INGARCH) model for time series of counts that also exhibit the different levels of dispersion. We demonstrate that the AHP-INGARCH model is comparable to some existing INGARCH models. Additionally, the model can cover a wider range of dispersion. The maximum likelihood estimation can be used to estimate the parameters of the proposed model. Applications to three real-life data sets related to polio, internet protocol and daily COVID-19 new deaths underscore the usefulness of the proposed model in studying both over-dispersed and under-dispersed time series of counts.
The effects of fear and delay on a predator-prey model with Crowley-Martin functional response and stage structure for predator
Authors: Kong Weili , Shao Yuanfu
Published: October 2023

Taking into account the delayed fear induced by predators on the birth rate of prey, the counter-predation sensitiveness of prey, and the direct consumption by predators with stage structure and interference impacts, we proposed a prey-predator model with fear, Crowley-Martin functional response, stage structure and time delays. By use of the functional differential equation theory and Sotomayor's bifurcation theorem, we established some criteria of the local asymptotical stability and bifurcations of the system equilibrium points. Numerically, we validated the theoretical findings and explored the effects of fear, counter-predation sensitivity, direct predation rate and the transversion rate of the immature predator. We found that the functional response as well as the stage structure of predators affected the system stability. The fear and anti-predation sensitivity have positive and negative impacts to the system stability. Low fear level and high anti-predation sensitivity are beneficial to the system stability and the survival of prey. Meanwhile, low anti-predation sensitivity can make the system jump from one equilibrium point to another or make it oscillate between stability and instability frequently, leading to such phenomena as the bubble, or bistability. The fear and mature delays can make the system change from unstable to stable and cause chaos if they are too large. Finally, some ecological suggestions were given to overcome the negative effect induced by fear on the system stability.

Protecting Oroqen folk songs is not only the only way to reproduce Chinese traditional music culture, but also the only way to rebuild its national spirit and enhance national cultural confidence. In view of the modernity problems of Oroqen folk songs in the current process of inheritance and protection, this paper puts forward the management and optimization methods of music audio-visual archives resources under the background of big data. This paper analyzes and discusses the resource management path of folk music audio-visual archives in Oroqen in the era of big data and designs a set of perfect digital music audio-visual archives resource management platform, which can not only facilitate the collection, storage, management, and utilization of paper files and electronic files in archives, but also optimize the retrieval algorithm of archives. The resource allocation algorithm based on Nash equilibrium solution is used to optimize it. The simulation results show that the proposed method reduces the information resource allocation time and improves the demand satisfaction.
Empirical Comparison of Energy Efficiency Between 3-Tier and High-Speed 3-Tier Network Topologies
Authors: Alkoshman Manal , Atiewi Saleh
Published: October 2023

The high levels of energy use for cloud computing affect carbon emissions and climate change. This research thoroughly compares the energy utilisation of conventional and high-speed three-tier data centres (DCs). The green cloud simulator (GCS) was used to compare network configurations and energy-saving algorithms for each cloud's energy consumption in 10 trials. The power saver schedule algorithm used the least server energy, while the green and RR schedule algorithms used more. Despite the testing of several energy conservation approaches, core switch and aggregate switch energy usage remained unchanged. Although the high-speed three-tier DC architecture used more energy than the standard design, this is a key difference between the two network topologies. The authors discuss the power saver schedule algorithm's benefits for server energy utilisation. This study shows how three-tier DC architecture can save money by reducing core switch and aggregation switch energy use. These evaluations should include the make span coefficient, and future research should focus on DC transform energy-saving techniques.
A Preliminary Study on Graduate Student Instructors' Exploration, Perception, and Use of ChatGPT
Authors: Bao Yingling , Li Belle
Published: October 2023

Research on teachers' technological pedagogical content knowledge (TPACK) has been burgeoning recently. Yet, little is known about how teachers integrate AI tools such as ChatGPT in language teaching. This preliminary qualitative study investigates the exploration and incorporation of ChatGPT in language teaching by graduate student instructors (GSIs). By analyzing data from questionnaires, focus group interviews, screenshots of interactions with ChatGPT, and participants' lesson plans, this study shows how instructors develop their knowledge about ChatGPT and mobilize content and pedagogy knowledge to enact technology integration. Findings reveal that GSIs adopted various strategies when exploring the affordances of ChatGPT. Furthermore, while GSIs form positive perceptions of ChatGPT affordances, negative perceptions pertain to its limited capacity to process the Chinese language. Lastly, GSIs drew on various aspects of TPACK to design lessons, among which content knowledge and its interplay with technology seem to be prominent.
Why People in Kuwait Do Not Prefer Online Learning Systems
Authors: Abbas Hasan A. , Rouibah Kamel , Baqer Ahmad M.
Published: October 2023

Many studies have investigated the burnout model in Western societies but have ignored it in the Arab region. They have also found that the burnout model does not have clear cut dimensions. To fill this gap, the authors applied a modified version of the burnout model to college students in Kuwait to measure their satisfaction with an e-learning system during the Coronavirus pandemic. They survey 573 college-level students in Kuwait on their preference of online learning. The results indicated that the perceived workload and exhaustion (as a burnout variable) had more of an effect on dissatisfaction with e-learning than system quality. Further, they also found that dissatisfaction was negatively associated with e-learning acceptance.

Authors: Jing Qi , Muhammad Yasir
Published: October 2023

In recent years, with the increasing homogenization of competition among live commerce streamers, the industry ecology has been deteriorating. As a rising star in the field of livestreaming, knowledge-based streamers have brought a huge impact to traditional ones and achieved great business success. They not only create a new trend of differentiated competition among streamers, but also to some extent promote the transformation and upgrading of live commerce industry. To the authors' best knowledge, no studies in research literature have focused on the practical logic of knowledge-based streamers. Therefore, this research takes knowledge-based streamers of China as the research objects, collects and analyzes relevant news, policies, literature, and interview materials. Through the grounded theory, this research summarizes and refines these practical experiences, explores the practical logic in the process of livestreaming, and establishes a theoretical model.

Electrically conductive composites based on silicates offer new possibilities for the use of composites not only in civil engineering but in the construction industry in general. These materials can be used, for example, for resistive heating of roads and highways, surge protection for buildings, EMI shielding, or smart sensors. This article focuses on cement composites where graphite powders are used as electrically conductive fillers. The research focuses on the behaviour and the change of the electrically conductive properties of these materials under mechanical loading. The changes in the resistivity of the composites when loaded in different directions on the electric current flow was investigated and studied. The specimens were loaded in the direction of electric current and in the direction perpendicular to the electric current.
Effect of Secondary Fillers in Polymeric Material for CIPP on Fresh Processability
Authors: Jakubíková Karolína Hudec , Drochytka Rostislav
Published: October 2023

The paper focuses on developing and testing polymeric materials for the CIPP method. The CIPP (cured-in-place pipe) method is a method, that focuses on rehabilitation without excavation, especially for sewer pipes. These developed materials are then saturated in special textile sleeves, which are pulled and cured directly in the sewer. Foam waste glass, basalt filler, waste glass from solar panels, and fly ash were used as secondary fillers for the tested formulations. The secondary raw materials in these materials improve the mechanical performance of the resulting composites and, in addition, improve their environmental and economic impact. The main subject of this paper is to verify the processability of these materials and verify their application/saturation into the textile lining. In particular, the determination of kinematic viscosity, fresh density, comparison of workability, and the so-called application test. The aim is to assess the influence of the added secondary raw materials on the processability and correct application to the lining so that the results are better or comparable to the reference material or have even better properties than the mass reference. According to research, basalt filler appears to be the most suitable secondary filler.

Asbestos-the Silent Killer: a review of screening and diagnostic imaging of asbestos related lung disease
Authors: Khan Ali Nawaz , Al-Jahdali Hamdan , Irion Klaus L. , Koteyar Shyam Sunder
Published: October 2023

An epidemic of asbestos related lung (ARLD) disease stares the developed countries in the face. However, these countries have lately banned the use of asbestos. Nevertheless, Western countries have no qualms of selling asbestos to poor countries that have no credible health safety regulations in the work place. Epidemiologic studies predicted a decline in incidence of ARLD in the US after the year 2000, with a peak incidence in the UK in 2020. Lung cancer (LC) develops in up to 25% of asbestos workers. In exposed nonsmokers, there is 5-fold increase. In exposed individuals, smoking further increases the risk of bronchogenic carcinoma by 80-90-fold. However the silent killer, asbestos is still active in developing countries and is likely to remains so in decades to come. In the Middle East, immigrant workers still work in asbestos environment. Saudi Arabia is the only major country in the Middle East that has banned asbestos, but workers continue to be at risk due to maintenance work on buildings built before the ban. As asbestos related lung disease remains silent in many and has a long latent period, the only way of detecting these diseases early is by diligence being aware of the patient’s occupational history and affective imaging. Presently there is no credible screening for ARLD. Here we review imaging studies in ARLD to increase awareness of this potentially lethal disease. Whereas diagnosis of ARLD is a matter for compensation in the developed countries it is a matter of survival in the developing world where industrialization has just begun and may take decades to remove the threat of asbestos. In this review we will discuss the clinical, radiologic, and pathologic features of ARLD.

An 80-year-old man presented with heterogeneous ground glass opacity, with interlobular septal thickening in the left lower lobe. The histology of a surgical lung biopsy showed alveolar proteinosis. Computed tomography revealed that the ground glass opacity and interlobular septal thickening observed dorsally in the supine position migrated to the ventral side in the prone position. To the best of our knowledge, this is the first report of a posture-dependent migrating shadow in a patient with pulmonary alveolar proteinosis.

Published: October 2023

An 81-year-old male with a history of symptomatic bradycardia controlled by a pacemaker presented to our institution with three days of persistent hiccups. He denied any pulmonary symptoms and his initial evaluation showed no evidence of tachypnea, tachycardia, or hypoxia. Pacemaker malfunction or migration of the pacer leads was ruled out as an etiology and no intracranial pathology was present. Admission chest radiograph was normal but a computed tomography of the chest demonstrated a left lower lobe pulmonary embolus. After treatment with anticoagulation was initiated, the hiccups resolved within the next week. This is a unique case presentation of hiccups as the only presenting symptom of an otherwise asymptomatic pulmonary embolism.

A 27-year-old man presented with a large solitary lung mass. Transbronchial lung biopsy and lobectomy specimens showed malignant melanoma. A thorough search for a primary melanoma lesion, including an ophthalmic exam and a dermatologic exam with special attention to the skin, mucous membranes, genitals, perineum, scalp, and nails showed no lesions suspicious for a melanoma. The diagnosis of primary malignant melanoma of the lung was considered. Whole-body positron emission tomography scan with computed tomography fusion imaging at the time of diagnosis showed no evidence of tumor outside the chest, and the diagnosis of primary malignant melanoma of the lung was confirmed. The prognosis of patients with this exceedingly rare neoplasm is poor, though surgical intervention may be warranted in some cases.
A case of vocal cord dysfunction with Takotsubo cardiomyopathy: is there a link?
Authors: Ye Xuan , Aziza Sultana , Gomes Sean , Lancashire William , Thomas Paul S.
Published: October 2023

Vocal cord dysfunction (VCD) is an underrecognised cause of dyspnoea as it is seldom life threatening, and also difficult to diagnose. However, there have been rare accounts of VCD, as in the present case, which have led to haemodynamic instability. This patient with VCD episodically developed acute pulmonary oedema, bilateral pleural effusions and Takotsubo cardiomyopathy, treated effectively with tracheostomy. This presentation hints at the possible existence of a common pathophysiological mechanism, namely, forced inspiration against a closed airway or sympathetic overstimulation.

The nose is a vital organ and an important aesthetic unit, being placed in the middle of the face. It is also one of the most frequently site involved by skin cancer, and surgical reconstruction can be sometimes challenging. We present two cases of full thickness nasal ala defect, managed with turnover flap with and without earlobe cartilage graft.

Bell’s palsy is the most common cause of facial paralysis, affecting one in every 60 people in their lifetime. Transcutaneously applied selective electrical muscle stimulation could potentially accelerate recovery from Bell’s palsy but this intervention remains controversial. Studies have shown benefit, but concerns for lack of efficacy and potential for worsening synkinesis remain. We performed a prospective controlled trial comparing outcomes at initial recovery and six months later with selective electrical muscle stimulation and usual physical therapy versus usual physical therapy alone in adults with acute Bell’s palsy. Outcomes were facial function assessed with the House Brackman and eFACE scales. Outcomes were evaluated at discharge and six months after discharge. Discharge occurred when participants were judged to be fully recovered by their treating therapist and supervisor. 38 adults participated in the study. Participants in the electrical stimulation group achieved maximal recovery twice as fast as the control group (2.5 weeks versus 5.2 weeks) with no significant differences in facial function or synkinesis between groups at any time point. This study is the first human trial of electrical stimulation in Bell’s palsy to follow patients 6 months from recovery and supports that selective electrical muscle stimulation accelerates recovery and does not increase synkinesis.
The effectiveness of project-based learning on students’ academic achievement in emergency nursing study

Projects necessitate students to choose and identify constructive models of investigation and materials while employing appropriate strategies for conducting learning activities. However, the effectiveness of such methods in the context of nursing-specific education has not been extensively explored. This study aimed to assess the effectiveness of project-based learning in emergency and critical care nursing courses for nursing students. This study employed a pre-experimental design. The research sample consisted of 123 students enrolled in the emergency, critical, and disaster management nursing course at Universitas Jember. The research involved a comparison of students' learning outcomes through written test questions before and after they completed a project. The results of the learning assessment before and after the project intervention were analyzed using the Wilcoxon Test. The results of the bivariate obtained a significance value of 0.0001. The results of this statistical test can be concluded that the project-based learning method is effective in increasing the knowledge of emergency, critical and disaster nursing. The project-based learning method proves to be effective in enhancing students' comprehension of emergency, critical, and disaster nursing. Nursing educational institutions can consider the incorporation of this method in curriculum design to create more effective learning strategies. It serves as a promising alternative for enhancing the quality of nursing education. Further research is necessary to validate these findings and investigate various factors that may influence the effectiveness of project-based learning methods in the nursing context.
Ingestion of minoxidil associated with elevated transaminases in the absence of ischemic hepatitis
Authors: Shanahan Elizabeth , Mitchell Christopher , Chen Richard , Walsh Steven
Published: October 2023

Minoxidil is a direct-acting vasodilator that induces relaxation of the vascular endothelium, and historically, it has been used as an antihypertensive agent. It caused hypertrichosis, resulting in its typical use today as an alopecia treatment. Toxicity is characterized by hypotension and tachycardia, often requiring treatment with α-adrenergic agonists. A previously healthy 18-year-old woman presented to the emergency department three hours after ingesting 60 mL of 5% W/V topical minoxidil solution. Initial vitals included sinus tachycardia at 117 beats per minute and a blood pressure of 92/44 mmHg. Laboratory analyses performed three hours post-ingestion revealed elevated aspartate and alanine aminotransferases (224 and 384 IU/L, respectively). Acetaminophen and ethanol concentrations were undetectable. Isotonic crystalloid, N-acetylcysteine, phenylephrine, and midodrine were administered. She developed pulmonary edema, requiring diuresis and supplemental oxygen via a nasal cannula. She was discharged 108 hours post-ingestion after a full recovery. Minoxidil toxicity may be an uncommon etiology of abnormal transaminase concentrations.

West Nile Virus (WNV) is a vector-borne flavivirus primarily infecting mosquitoes, birds, horses and humans. WNV is responsible for asymptomatic infections or a variety of clinical manifestations ranging from mild febrile illness to neuroinvasive disease. The frequency and severity of WNV-related disease have lately increased in the European Union and in the neighbouring countries, with particular concern for the Mediterranean area. This trend is probably connected to a raise in both average temperatures and rainfall, favourable factors for WNV spread. Due to the marked and expanding geographical distribution of the vector and the high endemic potential of WNV, this virus is worldwide considered an increasing public health apprehension. An augmented burden of WNV severe illness has been reported. Alarmingly, no vaccine or specific antiviral treatments are currently available for WNV infection. Hereafter, we will review the available information summarizing molecular biology, pathogenesis, clinical manifestations, epidemiology, diagnosis and therapy for WNV infection in humans.
