Published: January 2023

Background: Postoperative sore throat (POST) syndrome commonly occurs after general anesthesia and surgery, leading to patient discomfort. Objectives: This essay aims to assess the effect of using zinc-impregnated packs on sore throat and post-op nausea and vomiting after general anesthesia among patients undergoing septorhinoplasty. Methods: The sampling method was based on the patients’ gradual referral, and encompassing was performed using the randomized block. The participants were divided into four groups by random allocation technique considering the type of pharyngeal packs: (1) normal saline-impregnated vibril, (2) normal saline-impregnated gauze, (3) zinc solution-impregnated vibril, (4) zinc solution-impregnated gauze. The sample size required to compare the incidence of sore throat after septorhinoplasty was determined to be 220 patients. Results: Out of 220 patients undergoing septorhinoplasty, 55 were assigned to each group. According to A.S.A., most of the patients belonged to class I. In total, 5.5% and 15.1% had a history of gastroesophageal reflux disease (GERD) and smoking, respectively. There was no statistically significant difference among the four groups in terms of the sore throat immediately (P = 0.227), two h (P = 0.527), four h (P = 0.505), six h (P = 0.564) and 24 h (P = 0.481) after surgery. Results of pairwise comparison revealed no statistical difference between the groups receiving zinc and other groups. There was no statistically significant difference between the four groups in terms of the severity of sore throat. A statistically significant difference was observed between the gauze + zinc and gauze + normal saline groups regarding the incidence of nausea two hours after surgery (P = 0.0045). Conclusions: This study showed that applying topical zinc to the pack had no significant effect on reducing sore throat. However, there was a significant difference between the groups receiving zinc solution-impregnated gauze and normal saline-impregnated gauze in terms of the severity of nausea two h after surgery.

Authors: Saremi Hossein , Bidabadi Abbas , Seifrabiei Mohammadali
Published: January 2023

Background: Scaphoid nonunion is not uncommon and may eventually lead to complications such as deformity, instability, and degenerative changes. Open reconstruction could jeopardize vascular supply and cause capsular contracture. Arthroscopic treatment of scaphoid nonunion is an effort to avoid such complications. Objectives: This study evaluated the mid-term results of arthroscopic assisted treatment of scaphoid nonunion. Methods: Fifteen patients who underwent arthroscopic assisted treatment of scaphoid nonunion were included in the study. Ten patients had scaphoid waist fractures, while in five patients, the fracture was in the proximal pole. The union was evaluated radiographically three months, six months, and one year after surgery. The range of active motion, grip strength, and standard disability questionnaires such as disabilities of the arm, shoulder, and hand (DASH), patient-related wrist evaluation (PRWE), and modified Mayo wrist scales were evaluated one year after surgery. Results: Based on radiographic findings, all patients' fractures were satisfactorily united after three months. Functional scores, motion range, and grip strength improved to an acceptable level. There was no complication, including infection or nerve damage. Conclusions: Arthroscopic treatment of scaphoid nonunion seems to be an effective method with low complications and favorable results.

Postawy Polaków wobec zapłodnienia pozaustrojowego in vitro
Authors: Mariański Janusz
Published: January 2023

W niniejszym artykule przedstawimy najpierw stanowisko Kościoła katolickiego w sprawie zapłodnienia pozaustrojowego in vitro oraz argumenty zwolenników tej metody. W drugiej części artykułu przedstawimy wyniki sondaży ogólnokrajowych dotyczących postaw dorosłych Polaków wobec zapłodnienia in vitro oraz postawy młodych Polaków dotyczących tej samej kwestii. Około trzy czwarte dorosłych Polaków dopuszcza w mniej lub bardziej wyraźny sposób praktykę zapłodnienia pozaustrojowego in vitro. Mniej jest tych, którzy zgadzają się w pełni ze stanowiskiem Kościoła katolickiego (około 20%). Wśród katolików dane te są nieco odmienne. Można ogólnie szacować, że nieco mniej niż dwie trzecie badanych katolików aprobuje procedury zapłodnienia pozaustrojowego in vitro i około trzecia część akceptuje stanowisko Kościoła katolickiego w tej sprawie. W tej dziedzinie można mówić o odchodzeniu od doktryny katolickiej i desakralizacji ludzkiego życia (od aprobaty do dezaprobaty).

Successful removal of remnant cystic duct stump stone using single-operator cholangioscopy-guided electrohydraulic lithotripsy: two case reports
Authors: Ryou Sung Hyeok , Kim Hong Ja
Published: January 2023

Cholecystectomy is the best method for treating gallstone diseases. However, 10%–30% of patients who undergo a cholecystectomy continue to complain of upper abdominal pain, dyspepsia, or jaundice—this is referred to as postcholecystectomy syndrome. Cystic duct stump stones are a troublesome cause of postcholecystectomy syndrome. Conventionally, surgery is mainly performed to remove cystic duct stump stones. However, repeated surgery can cause complications, such as postoperative bleeding, biliary injury, and wound infection. As an alternative method of surgery, endoscopic retrograde cholangiopancreatography is sometimes used to remove cystic duct stump stones, although the success rate is not high due to technical difficulties. Recently, peroral cholangioscopy, which can directly observe the bile duct, has been suggested as an alternative method. We report two cases in which a cystic duct stump stone was successfully removed via a single-operator cholangioscopy, after failure with an endoscopic retrograde cholangiopancreatography.

Background/Aims: The etiology of superficial non-ampullary duodenal epithelial tumors (SNADETs) remains unclear. Recent studies have reported conflicting associations between duodenal tumor development and Helicobacter pylori infection or endoscopic gastric mucosal atrophy. As such, the present study aimed to clarify the relationship between SNADETs and H. pylori infection and/or endoscopic gastric mucosal atrophy.Methods: This retrospective case-control study reviewed data from 177 consecutive patients with SNADETs who underwent endoscopic or surgical resection at seven institutions in Japan over a three-year period. The prevalence of endoscopic gastric mucosal atrophy and the status of H. pylori infection were compared in 531 sex- and age-matched controls selected from screening endoscopies at two of the seven participating institutions.Results: For H. pylori infection, 85 of 177 (48.0%) patients exhibited SNADETs and 112 of 531 (21.1%) control patients were non-infected (p<0.001). Non-atrophic mucosa (C0 to C1) was observed in 96 of 177 (54.2%) patients with SNADETs and 112 of 531 (21.1%) control patients (p<0.001). Conditional logistic regression analysis revealed that non-atrophic gastric mucosa was an independent risk factor for SNADETs (odds ratio, 5.10; 95% confidence interval, 2.44–8.40; p<0.001).Conclusions: Non-atrophic gastric mucosa, regardless of H. pylori infection status, was a factor independently associated with SNADETs.

Background/Aims: Image-enhanced endoscopy can detect superficial oro-hypopharyngeal squamous cell carcinoma; however, reliable endoscopy of the pharyngeal region is challenging. Endoscopy under general anesthesia during transoral surgery occasionally reveals multiple synchronous lesions that remained undetected on preoperative endoscopy. Therefore, we aimed to determine the lesion detection capability of endoscopy under general anesthesia for superficial oro-hypopharyngeal squamous cell carcinoma.Methods: This retrospective study included 63 patients who underwent transoral surgery for superficial oropharyngeal squamous cell carcinoma between April 2005 and December 2020. The primary endpoint was to compare the lesion detection capabilities of preoperative endoscopy and endoscopy under general anesthesia. Other endpoints included the comparison of clinicopathological findings between lesions detected using preoperative endoscopy and those newly detected using endoscopy under general anesthesia.Results: Fifty-eight patients (85 lesions) were analyzed. The mean number of lesions per patient detected was 1.17 for preoperative endoscopy and 1.47 for endoscopy under general anesthesia. Endoscopy under general anesthesia helped detect more lesions than preoperative endoscopy did (p<0.001). The lesions that were newly detected on endoscopy under general anesthesia were small and characterized by few changes in color and surface ruggedness.Conclusions: Endoscopy under general anesthesia for superficial squamous cell carcinoma is helpful for detecting multiple synchronous lesions.
The Prevalence of Teacher Tracking in High School Mathematics Departments
Authors: Nirode Wayne , Boyd Brian
Published: January 2023

This study examined the prevalence of teacher tracking in a population of 1,822 mathematics teachers in 184 high schools in a single state. Results showed that 70% of teachers were tracked by course level, course track, or both. Three fourths of high schools tracked at least 58% of their mathematics teachers. We also found significant differences in teaching assignments across quintiles of years of experience at a teacher’s current school. First-quintile teachers were the most likely to be assigned low-track or entry-level courses. In contrast, fifth-quintile teachers were the most likely to be assigned high-track or upper-level courses. These findings indicate that the tracking of mathematics teachers is a prevalent and persistent inequitable structure in most high schools.

Selecting the Optimal Naval Ship Drainage System Design Alternative Based on Integer Linear Programming, TOPSIS, and Simple WISP Methods
Authors: Kirmizi Mehmet , Karakas Serkan , Uçar Hakan
Published: January 2023

_

Ship design is a complex study requiring the coordination of many disciplines and accurate calculations, as well as cost considerations. Thus, ship designers have to design the naval ships that successfully fulfill the desired performance in a cost-effective manner with respect to international and national rules and regulations. In this context, finding the optimum solution for the design has been an important challenge for ship designers. Design optimization is selecting the best solution among many viable solutions based on a criterion or multicriteria and inherently coupled with the design cycle. This study presents an application of the integer linear programming and multicriteria decision-making (MCDM) methods of Technique for Order Preference by Similarity to an Ideal Solution (TOPSIS) and Simple Weighted Sum Product (WISP). A design of the ship drainage system is considered as the case study for this purpose. Based on the usage and location of the ejectors and drainage pumps, four design alternatives and 12 scenarios for each alternative are proposed. The optimization problem is solved for each design alternative, and an optimal design solution among alternatives is evaluated by TOPSIS and Simple WISP methods. The similarity of the solutions from the two MCDM methods is measured by Cosine Similarity, which indicates a strong similarity.

Introduction

Ship design is a complex, iterative, and sophisticated process affected by a number of factors. Among these factors, the issue of cost efficiency has come to the fore along with the project method and system integration during the last century. Therefore, ship designers have to design the most cost-effective ship for a specified purpose regarding national and international rules and regulations. Within this context, the cost considerations in the design calculations of the systems onboard are as important as their accuracy and adequacy. Thus, finding the optimum solution within the given limits is challenging for ship designers, engineers, and system integrators. For this purpose, design optimization tools have been implemented in ship design.
Family involvement and school effectiveness in primary education
Authors: Aierbe-Barandiaran Ana , Bartau-Rojas Isabel , Oregui-González Eider
Published: January 2023

The commonly accepted premise that collaboration among the educational community leads to school improvement and greater student achievement is not always fulfilled due to the diverse reality of schools and various initiatives to promote family participation. This work addresses the perception of teachers, school management teams and educational inspection of family-school-community relations in 23 primary schools in the Basque Autonomous Community, characterized by different criteria related to school effectiveness-ineffectiveness, aiming to identify good practice leading to school improvement. The study is descriptive-exploratory-exploratory-explanatory with mixed methodology, using questionnaires, in-depth interviews and discussion groups. Results show family involvement is mediated by teaching staff´s personal factors, that all schools try to promote family collaboration, though forms of participation vary, and those which work best are proactive, stressing different collaboration dimensions. Conclusions include adopting a systemic approach, review and updating of training modalities, and assessment of teaching competences for collaboration.

La premisa ampliamente aceptada de que el trabajo colaborativo entre los diferentes agentes de la comunidad educativa redunda en la mejora escolar y en mayores logros alcanzados por el alumnado no siempre se cumple debido a la realidad diversa que presentan los centros y a las diferentes iniciativas para impulsar la participación familiar. El estudio aborda la percepción que docentes, equipos directivos e inspección educativa tienen de las relaciones familia-escuela-comunidad en 23 centros de primaria de la Comunidad Autónoma Vasca, caracterizados por diferentes criterios de eficacia-ineficacia escolar, con la finalidad de identificar buenas prácticas que contribuyan a la mejora escolar. Se trata de un estudio descriptivo-exploratorio-explicativo de metodología mixta, con empleo de cuestionarios, entrevistas en profundidad y grupos de discusión. Los resultados muestran que la implicación familiar está mediatizada por factores personales del profesorado, que todos los centros tratan de impulsar la colaboración familiar, aunque las formas y acciones de participación varían, y que aquellos que mejor funcionan tienen una actitud proactiva, con énfasis en dimensiones diferentes de colaboración. Entre las conclusiones cabe destacar la adopción de un enfoque sistémico, la revisión y actualización de las modalidades formativas, y la evaluación de las competencias docentes para la colaboración.

Authors: Vallejos-Flores Miguel , Capa-Luque Walter , Caycho-Caja Aaron , Chavez Santamaria Alexandra , Reyes-Baca Gino , Bello-Vidal Catalina
Published: January 2023

Background: The identification of the reasons for marijuana use has been supported by instruments such as the MMM. Despite its importance, there are still no valid brief versions of this instrument in Latin American countries. This paper seeks to fill this gap by providing evidence of validity and reliability, as well as the structural invariance of the MMM. Method: The sample consisted of 1164 male and female marijuana users, aged between 18 and 49 years, from Lima and Callao. Results: The factor analysis found a pentafactorial structure. The brief version (MMM-P15) and the wide MMM showed favorable properties from structure and reliability (ꙍ > 0.88, H > .84) with a slight superiority of the short instrument (RMSEA = .058 [CI 90% .050, .067], SRMR = 0.044, TLI = 0.99, CFI = 0.99). Likewise, both versions maintain the invariance of the instrument according to sex and evidence of internal validity was found (AVE > 0.50). Conclusions: The MMM-P15 shows psychometric properties that support its use in both male and female marijuana users, and it is a short, versatile, and useful instrument for research purposes even in clinical settings.

Antecedentes: La identificación de los motivos por los cuales se consume marihuana se ha visto apoyada por instrumentos como el MMM. A pesar de su importancia, aún no se cuenta con versiones breves válidas de este en países latinoamericanos. Este trabajo busca cubrir esta carencia aportando evidencia de validez y confiabilidad, así como la invarianza estructural del MMM. Método: La muestra comprende 1164 consumidores de marihuana, varones y mujeres, con edades entre 18 y 49 años, de Lima y Callao. Resultados: El análisis factorial halló una estructura pentafactorial. La versión breve (MMM-P15) y extensa (MMM) muestran favorables propiedades de estructura y consistencia interna (ꙍ > 0.88, H > .84) con una ligera superioridad del instrumento corto (RMSEA = .058 [IC 90% .050, .067], SRMR = .044, GFI = .99, TLI = .99, CFI = .99). Asimismo, ambas versiones mantienen la invarianza según el sexo y se encontró evidencia de validez interna (AVE > 0.50). Conclusiones: El MMM-P15 evidencia propiedades psicométricas que respaldan su uso tanto en hombres y mujeres consumidores de marihuana, además es un instrumento corto, versátil y útil para fines de investigación incluso en contextos clínicos.

Authors: Albertos Gómez Daniel
Published: January 2023

Esta investigación tiene dos objetivos: aportar evidencia acerca de la eficacia de la metodología Inquiry Based Science Education (IBSE) para desarrollar la competencia científica de estudiantes de 12-13 años y establecer una manera fiable de evaluar dicho proceso de aprendizaje mediante un test diseñado ad-hoc.  Se empleó un diseño cuasi-experimental, con tres grupos que realizaron un test con medidas antes y después del tratamiento. Dicho test obtuvo un valor de fiabilidad de 0,75 en el estadístico alfa de Cronbach. El análisis de la varianza realizado mostró que el grupo que recibió el tratamiento mejoró su rendimiento en competencia científica de manera significativa con respecto a los grupos que siguieron un tratamiento de enseñanza expositiva. Igualmente, se observó que el tamaño del efecto fue muy alto (d = 1,2). El test se ha comportado como una herramienta útil en la evaluación cuantitativa de habilidades científicas en estudiantes de 1º de ESO.
Romantic Traditions in the Works of Ivan Sokolov on the Example of Intertextual Poetics of "Gospel Paintings"
Authors: Sycheva Natalia Nikolaevna
Published: January 2023

The article is devoted to the work of Ivan Glebovich Sokolov (born 1960), which unfolds in many areas of activity, and among them the main one stands out – composer and pianist. Performance directly affects his composer's searches. Realizing the special impact of the music of romantic composers on listeners, I. G. Sokolov changes the focus of his work from a «conceptual» vector to a traditional style of writing. He creates a number of works directly related to the romantic tradition, among them the piano cycle “Gospel Pictures» (2012) stands out, in which the high role of associative links with the heritage of romantic composers (J. Brahms, F. Liszt, S. V. Rachmaninov, A. N. Scriabin, P. I. Tchaikovsky, F. Chopin, R. Schumann). The focus of the article is the intertextual layer in the «Gospel Pictures», which is realized at two levels: compositional and intonational-thematic (quotes, quasi-quotes, allusions), the latter is given special attention in the article. As a result of the analysis, the author comes to the conclusion that the noted material, which is directly related to the musical culture of romanticism, merges into a single whole with the style of the musical language of the piano cycle, forming a «mono-stylistic» (G. V. Grigorieva) musical fabric, which emphasizes the relevance the concept of extending romantic traditions in modern domestic musical culture. At the same time, this perspective of the study confirms the concept of A. V. Mikhailov about the «phenomenon of the omnipresence of romantic music», as well as its «indestructibility» and «immortality» in the process of evolution of musical culture.
Une maison d’édition pour la jeunesse indépendante et militante. Engagement, traduction et questions de genre chez Lo Stampatello
Authors: Illuminati Valeria
Published: January 2023

This paper analyses the editorial policies of an Italian independent publishing house, Lo Stampatello. Drawing on the theoretical and methodological tools of Translation Studies and Gender Studies as well as on discourse analysis, the study examines the ethos projected by the publisher. The analysis relies on a corpus of interviews (written and oral) and it also considers the catalogue of the publishing house. The analysis shows that Lo Stampatello defines itself, by its very nature and from the very outset, as a militant publishing house. In the words of the publishers and in the chosen editorial policy, a strong political and ethical commitment can be observed, one that is openly claimed by the publishers. Gender issues take therefore centre stage, not least due to the position of the publishing house in the Italian literary field and to the social and cultural context of this country.
Single-cell profiling of lncRNAs in human germ cells and molecular analysis reveals transcriptional regulation of LNC1845 on LHX8

Non-coding RNAs exert diverse functions in many cell types. In addition to transcription factors from coding genes, non-coding RNAs may also play essential roles in shaping and directing the fate of germ cells. The presence of many long non-coding RNAs (lncRNAs) which are specifically expressed in the germ cells during human gonadal development were reported and one divergent lncRNA, LNC1845, was functionally characterized. Comprehensive bioinformatic analysis of these lncRNAs indicates that divergent lncRNAs occupied the majority of female and male germ cells. Integrating lncRNA expression into the bioinformatic analysis also enhances the cell-type classification of female germ cells. Functional dissection using in vitro differentiation of human pluripotent stem cells to germ cells revealed the regulatory role of LNC1845 on a transcription factor essential for ovarian follicle development, LHX8, by modulating the levels of histone modifications, H3K4me3 and H3K27Ac. Hence, bioinformatical analysis and experimental verification provide a comprehensive analysis of lncRNAs in developing germ cells and elucidate how an lncRNA function as a cis regulator during human germ cell development.
On a Mission to Break Ground for a More Democratic School System
Authors: Grevle Tessa Eriksen
Published: January 2023

The importance of building democratic competency in the face of current global challenges cascades down into national curricula. Illustratively, in 2020, Norway introduced a new national curriculum that conveyed an expectation that students should experience a democratic school society in practice. In response to this new curriculum, in 2019, an upper secondary school in Norway decided to embark on a mission to develop and implement a new pedagogical model. The ambition was to increase the students’ sense of codetermination and participation in school, the local community, and society at large. Subsequently, an interdisciplinary pedagogical model has been in development at the school, in which the subject content is organized according to overarching topics. These topics are presented to students as quests called learning missions.
Through in-depth interviews with teachers and leaders currently working on developing the new pedagogical method at the school, the current article investigates the challenges and opportunities the participants encountered in this process. The data have been coded through a stepwise deductive-induction method and analyzed using Bernstein’s concepts of classification and frame. The participants identified the inflexible organizational structures of the school—such as the school administrative system, the building, assessments, and the set timetable—as aspects that made it challenging for the school to depart from the dissemination-based approach to education. Inversely, the implementation of interdisciplinary topics in the Norwegian National Curriculum is one example of a structural change that the participants thought had opened up more flexibility. However, the participants experienced that this flexibility was not extended into the regulations controlling how time is spent in school or the assessment forms. Hence the article concludes that structural changes are necessary to enable the growth of pedagogical models that can increase students’ codetermination, active participation, and real-life experiences in schools.

Published: January 2023

Background

Diabetes is one of the fastest-growing health emergencies of the 21st century, placing a severe economic burden on many countries. Current management approaches have improved diabetic care, but several limitations still exist, such as decreased efficacy, adverse effects, and the high cost of treatment, particularly for developing nations. There is, therefore, a need for more cost-effective therapies for diabetes management. The evidence-based application of phytochemicals from plants in the management of diseases is gaining traction.

Methodology

Various plants and plant parts have been investigated as antidiabetic agents. This review sought to collate and discuss published data on the cellular and molecular effects of medicinal plants and phytochemicals on insulin signaling pathways to better understand the current trend in using plant products in the management of diabetes. Furthermore, we explored available information on medicinal plants that consistently produced hypoglycemic effects from isolated cells to animal studies and clinical trials.

Results

There is substantial literature describing the effects of a range of plant extracts on insulin action and insulin signaling, revealing a depth in knowledge of molecular detail. Our exploration also reveals effective antidiabetic actions in animal studies, and clear translational potential evidenced by clinical trials.

Conclusion

We suggest that this area of research should be further exploited in the search for novel therapeutics for diabetes.

Published: January 2023

Cotton stalks are good raw material for bioethanol production due to its availability throughout the world, abundance, high carbohydrate content and not involved in any food chain. Due to recalcitrant nature of cotton stalks pre-treatment, hydrolysis were not effective. In the present study pre-treatment with ammonia at room temperature for 1 week period and 121oC for 60min were attempted and it is compared with the standard 0.2M NaOH treatment. 1.5% ammonia pre-treatment at room temperature for 1 week found to remove 86% of lignin and subsequently undergone 75.92% acid hydrolysis. The acid hydrolysate obtained consists less lignin and furfurals and fermented to 5.75% ethanol with 91% fermentation efficiency with saccharomyces cerevisiae. Hence dilute ammonia pre-treatment for a week was found to be effective for bioethanol production using cotton stalks.
