Authors: Wali Haytham A. , Tabb Deanne , Baloch Saeed A.
Published: March 2023

Introduction:

Acute acalculous cholecystitis is an acute gallbladder inflammation in the absence of cholelithiasis associated with high morbidity and mortality rates. Fungal organisms are an infrequent cause of gallbladder infections. Although many coronavirus disease-19 (COVID-19) patients reported gastrointestinal symptoms, there is little evidence of gallbladder and biliary tract involvement. we report a case of fungal acute acalculous cholecystitis secondary to COVID-19.

Case Presentation:

A 71-year-old man with a past medical history of benign prostatic hyperplasia, essential hypertension, and hyperlipidemia was admitted for COVID-19 and received appropriate treatment with dexamethasone, remdesivir, and convalescent plasma. The patient continued to be lethargic, weak, and had elevated inflammatory markers. He was transferred to the intensive care unit (ICU) for intubation and mechanical ventilation. The total bilirubin started to increase over the following days and reached 8 mg/dL (136.8 μmol/L). The ultrasound did not show cholelithiasis and the bile culture grew Candida albicans, indicating acalculous Candida cholecystitis. The patient had a significant deterioration in clinical status and passed away after being transferred to comfort care.

Conclusion:

Our case represents acute acalculous cholecystitis possibly secondary to COVID-19 infection that was resulted in an invasive fungal infection involving the gallbladder Future research could help facilitate a better pathophysiological understanding of gallbladder complications and provide a more precise explanation of the long-term effects of COVID-19.

Background:

In this study, we aimed to identify the oncological outcomes in colon cancer patients who underwent elective versus emergency curative resection.

Methods:

All patients who underwent curative resection for colon cancer between July 2015 and December 2019 were retrospectively reviewed and analyzed. Patients were divided into two groups based on the presentation into elective and emergency groups.

Results:

A total of 215 patients with colon cancer were admitted and underwent curative surgical resection. Of those, 145 patients (67.4%) were elective cases, and 70 (32.5%) were emergency cases. Family history of malignancy was positive in 44 patients (20.5%) and significantly more common in the emergency group (P = 0.016). The emergency group had higher T and TNM stages (P = 0.001). The 3-year survival rate was 60.9% and significantly less in the emergency group (P = 0.026). The mean duration from surgery to recurrence, 3-year disease-free survival, and overall survival were 1.19, 2.81, and 3.11, respectively.

Conclusion:

Elective group was associated with better 3-year survival, longer overall, and 3-year disease-free survival compared to the emergency group. The disease recurrence rate was comparable in both groups, mainly in the first two years after curative resection.
Prevalence of Ice-Ice Disease in Kappaphycus spp. and Eucheuma denticulatum Farms in Sibutu, Tawi-Tawi, Philippines
Authors: Tahiluddin Albaris B. , Damsik Samiya U.
Published: March 2023

Kappaphycus spp. and Eucheuma denticulatum are commercially farmed in the world, notably in tropical countries such as Indonesia, Philippines, and Malaysia. Diseases and pests, particularly ice-ice disease, are the major hurdles in the sustainability of eucheumatoid seaweed culture. In this study, ice-ice disease prevalence in Kappaphycus and Eucheuma farms in Sibutu, Tawi-Tawi, Philippines, was assessed and compared according to species, farm depth, and time. Results revealed that in deep water farms, ice-ice disease prevalence was significantly lower in K. striatus (4.29±0.97%) than in K. alvarezii (10.53±2.64%) in July. In shallow water farms, E. denticulatum had the highest ice-ice prevalence (21.97±1.73%) significantly among the assessed seaweed species during August, and K. alvarezii had the lowest ice-ice disease occurrence (5.43±1.98%) significantly during September. In terms of depth water farm and time comparison, ice-ice disease prevalence (7.41±1.50% - 27.04±4.66%) in deep water (exceeding 2.47±0.16 m during low tide) did not differ significantly from that prevalence (11.35±1.69% - 12.91±1.93%) in shallow water farms (0.61±0.29 m during low tide) across time. This study suggests that ice-ice disease is still a prevalent and persistent problem in eucheumatoid seaweed farming.

Published: March 2023

Найдены интегралы движения для недавно введенной деформированной многочастичной системы Руйсенарса-Шнайдера, которая является динамической системой для полюсов эллиптических решений решетки Тоды со связью типа B. Наш метод основан на том факте, что уравнения движения этой системы совпадают с уравнениями движения для частиц Руйсенарса-Шнайдера, слипающихся в пары, в которых расстояние между частицами фиксировано и принимает специальное значение. Также для деформированной системы Руйсенарса-Шнайдера найдены преобразования Бэклунда и интегрируемая версия этой системы в дискретном времени. Показано, что эта последняя является динамической системой для полюсов эллиптических решений полностью дискретного уравнения Кадомцева-Петвиашвили типа B. Кроме того, предложен полевой аналог деформированной системы Руйсенарса-Шнайдера на пространственно-временной решетке.

Group-theoretic Johnson classes and a non-hyperelliptic curve with torsion Ceresa class
Authors: Bisogno Dean , Li Wanlin , Litt Daniel , Srinivasan Padmavathi
Published: March 2023

Let l be a prime and G a pro-l group with torsion-free abelianization. We produce group-theoretic analogues of the Johnson/Morita cocycle for G -- in the case of surface groups, these cocycles appear to refine existing constructions when l=2. We apply this to the pro-l etale fundamental groups of smooth curves to obtain Galois-cohomological analogues, and discuss their relationship to work of Hain and Matsumoto in the case the curve is proper. We analyze many of the fundamental properties of these classes and use them to give an example of a non-hyperelliptic curve whose Ceresa class has torsion image under the l-adic Abel-Jacobi map.

Authors: Ibujés-Villacís Juan , Franco-Crespo Antonio
Published: March 2023

In 2015, at the United Nations forum, the 17 Sustainable Development Goals (SDGs) were approved to be met by 2030. This research aims to know what has been the behavior of productivity and efficiency of the manufacturing industry in the province of Pichincha, Ecuador, and the relationship with the achievement of some goals of the SDG 8, 9 and 12. The research methodology has a quantitative, non-experimental, and longitudinal approach. The information from the economic and financial reports of the manufacturing companies between 2010 and 2018 was processed. The values of efficiency were estimated using the data enveloping analysis technique. With the annual information, the evolution of productivity and efficiency was predicted until 2022. In the nine years, the results show that the productivity indicators and the number of companies that are related to goals 8.2 and 8.3 depend on the size of the companies and would maintain a constant trend until 2022. In addition, in the same period, it was shown that efficiency has had variations, and its trend is to remain constant until 2022, which shows that there will be no progress in meeting the targets 9.4, and 12.2 of the SDGs for this industrial sector.

Authors: Simões Alan Caldas
Published: March 2023

Nesta investigação, resultado de minha pesquisa de doutorado, categorizei, descrevi e analisei os comportamentos de um professor (eu próprio, como observador participante) e alunos inseridos nas práticas informais de aprendizagem musical informal na escola. Como referencial teórico, utilizei os trabalhos desenvolvidos por Paulo Freire e Lucy Green. Utilizando como método de pesquisa a Grounded Theory, desenvolvi um modelo teórico que determina parâmetros para análise dos comportamentos docentes e discentes em práticas informais de aprendizagem musical na escola. Este modelo sugere a necessidade de superação do habitus escolar, herança da Educação Bancária que permeia a formação da escola brasileira, para alcançarmos o estado de consciência crítica sobre a realidade. Acredito que o modelo teórico desenvolvido pode auxiliar pesquisadores e professores de música interessados na aplicação das práticas informais de aprendizagem musical na escola, na reflexão e na avaliação de suas práticas docentes.

Pengaruh Penambahan Serbuk Kaca Pada Beton yang Direndam dengan Larutan Asam Sulfat Terhadap Kuat Tekan
Authors: Padang Israel
Published: March 2023

Penggunaan beton pada lingkungan agresif sangat berpengaruh pada keawetan dan nilai kuat tekan beton. Lingkungan tanah yang terkontaminasi dengan unsur kimia agresif dapat merusak bagian bawah tanah. Struktur beton yang kontak langsung dengan senyawa asam sulfat akan mempengaruhi kualitas kuat tekan beton karena asam sulfat dapat membuat beton menjadi korosi. Penelitian ini bertujuan untuk mengetahui pengaruh penambahan serbuk kaca pada beton yang direndam larutan asam sulfat pH3. Larutan asam sulfat merupakan larutan yang bersifat korosif terhadap beton. Proses pembuatan beton dilakukan dengan menambahkan serbuk kaca sebagai pengganti sebagaian pasir dengan kadar 10 % dan 20%. Benda uji yang digunakan pada penelitian ini adalah benda uji berbentuk silinder dengan diameter 15cm x tinggi 30 cm sebanyak 45 sampel yang akan diuji pada umur 3, 7, 14, 21, dan 28 setelah direndam larutan asam sulfat pH3. Penelitian eksperimental di Laboratorium Teknik Sipil Universitas Kristen Indonesia Toraja menunjukkan bahwa kuat tekan beton yang berusia 28 hari dengan penambahan 20 % serbuk kaca sebagai pengganti sebagian pasir memiliki kuat tekan optimal. Hasil yang didapat dari penambahan 20 % serbuk kaca pada umur 28 hari sebesa 20,75 MPa. Kuat tekan terus meningkat seiring penambahan kadar serbuk kaca dan umur dari beton yang direndam. Dengan demikian dapat disimpulkan bahwa penambahan serbuk kaca pada beton bisa menjadi alternatif untuk mengatasi serangan sulfat pada beton

Se presenta un estudio cuyo objetivo es evaluar el nivel de aprendizaje profundo metacognitivo y autodeterminado en relación con el rendimiento académico, de los alumnos de 1º de Grado de Ciencias de la Actividad Física y del Deporte, en la asignatura de Procesos de Enseñanza Aprendizaje, en el curso 2019-2020. Tres han sido los cuestionarios utilizados: el Cuestionario de procesos de estudio de dos factores revisado (R-SPQ-2F) de Biggs et al., (2001) traducido al español por Recio y Cabrero (2005); la versión en español (Matos, 2009), el Cuestionario de Clima de Aprendizaje Autodeterminado de Williams y Deci (1996), en su versión traducida y adaptada al castellano por Matos (2009), y el Cuestionario de Estrategias Metacognitivas de O´Neil y Abedi (1996), en la versión traducida y adaptada por Vallejos et al., (2012). Los resultados hallados muestran relaciones estadísticamente significativas tanto entre las variables del enfoque de aprendizaje profundo, clima de aprendizaje autodeterminado y metacognición, estrechamente ligadas con el rendimiento académico, independientemente de la procedencia de los estudiantes, Bachillerato o de Ciclo de Grado Superior (CGS). Se hallan diferencias estadísticamente significativas entre el modo de aprender de los estudiantes según su procedencia. Se hace un análisis de las implicaciones que debería tener en cuenta la docencia universitaria.

Abstract. The present study is focused on assessment the students´ level of metacognitive and self-determined deep learning in relation to academic performance.  All participants studied 1st Grade of Physical Activity and Sports Sciences, in the subject of Teaching-Learning Processes, in the 2019-2020 academic year. There have been three questionnaires used: the revised Two-Factor Study Process Questionnaire (R-SPQ-2F) by Biggs et al. (2001) translated into Spanish by Recio and Cabrero (2005); the Spanish version (Matos, 2009), the Self-Determined Learning Climate Questionnaire by Williams and Deci (1996), in its version translated and adapted into Spanish by Matos (2009), and the Metacognitive Strategies Questionnaire by O'Neil & Abedi (1996), translated and adapted version by Vallejos et al., (2012). The results found show statistically significant relationships between the variables of the deep learning approach, self-determined learning climate and metacognition, closely linked with academic performance, regardless of the origin of the students, Baccalaureate or Higher Degree Cycle. Statistically significant differences are found between the way of learning of the students according to their origin. An analysis is made of the implications of university teaching.

O desporto durante a pandemia de COVID-19: reflexões a partir do Modelo Analítico dos 5 E’s
Authors: Minuzzi de Souza Daniel , Astra van Amstel Naryana , Marchi Júnior Wanderley
Published: March 2023

A pandemia trouxe mudanças em diversos espaços e atividades humanas, entre elas o desporto. Ao envolver volumosas somas financeiras, principalmente quando pensamos os espetáculos esportivos das principais ligas do planeta, o desporto nos parece ter sido a mais “trivial” das atividades que buscou resistir às mudanças de risco biológico e econômico que caracterizaram a pandemia. O desporto, principalmente o de alto rendimento, ainda que muitos discordassem, praticamente sobreviveu como atividade essencial. No entanto, para ultrapassar tais obstáculos, mudanças e adequações se mostraram necessárias. Nesse ensaio, utilizamos a proposta do Modelo Analítico dos 5 E’s para compreender, a partir de uma perspectiva abrangente das dimensões propostas, quais foram as principais mudanças que afetaram o desporto em um momento histórico em que saúde e doença tomaram centralidade em nossas vidas. Notou-se alterações referentes ao consumo do esporte, nas relações de oferta e de demanda, nos comportamentos e nas emoções dos atletas e dos espectadores, bem como nos cuidados com saúde corporal. O esporte, como “atividade não essencial”, rapidamente adaptou-se ao novo “normal”, impulsionado pelos mecanismos de mercantilização e espetacularização.

Published: March 2023

Aim: to compare the effects of a therapeutic physical exercise programme based on mat Pilates method carried out at two intensities in a population with Parkinson´s disease. Method: 32 participants with Parkinson's disease were randomly assigned to the low-intensity Mat-Pilates group (n=16) and to the high-intensity Mat-Pilates group (n=16) with both interventions lasting 12 weeks. Lower limb strength (30 Second-Chair-Stand-test), gait speed (Timed-Up and Go), and feasibility were assessed. Results: A total of 29 participants attended 80% of the intervention sessions. The participation rate was 91.14% and 70.05% in the low intensity and high intensity groups, respectively. This research shows that after the intervention there was a significant increase in lower limb strength (low-intensity 8.31% vs high-intensity 34.25%) and gait speed (low-intensity 12.12% vs high-intensity 19.35%) for both groups, although the improvement in the high-intensity group was statistically greater than the low-intensity group. Conclusions: The Pilates method is evidenced as a comprehensive rehabilitation strategy in the treatment of patients with Parkinson's disease. Furthermore, an exercise regime based on the Pilates method at high intensity seems to lead to significant improvements in lower limb strength and an improvement in gait speed for this type of patient.

Published: March 2023

We employed the Brazilian Mood Scale (BMS) through Google Forms to assess the mood state of the athletes, which was sent to them at 8 pm the day before the first match. We considered only responses received until 10 pm (GMT-3). In addition to the BMS, we included two extra questions: "last night's sleep hours" and "how do you feel now?". The athletes were required to choose one of the following five items: very bad, bad, regular, good, or excellent. We collected statistical data of the matches, including points scored, points conceded, set , set defeats, matches won, and match defeats. To verify the correlation and differences between variables, we employed Bayesian analysis. The Bayesian ANOVA model, which included sleep quality on fatigue, was 12.465 times more likely than the null model. Post-hoc analyses revealed that bad sleepers were 5.545 times more likely to experience more fatigue than good sleepers. Our findings suggest that worse sleep quality is associated with a higher likelihood of experiencing increased fatigue. We also found anecdotal evidence, using Bayesian analysis, for a potential interference of sleep quality in confusion, vigor, and tension. However, when testing the interference of sleep quality in depression or anger using frequentist analysis, we did not detect any significant differences. Finally, our data did not support any hypotheses of interference of sleep quality in match statistics.
Key words: Bayesian analysis, fatigue, depression, confusion, sport, performance.
