Preliminary impression for maxillary defect: A two‐step technique
Authors: Naveau Adrien 
Published: September 2023

AbstractPreliminary impressions must record the periphery and height of maxillary defects to allow for an eventual extension of the master impression tray. These impressions are usually made with irreversible hydrocolloid. Carrying the impression material into the defect can be complex, especially in the case of a limited oral opening. Moreover, the patient can be harmed during the removal procedure, and material may be stuck in anatomical structures. The technique presented in this article avoids these issues in any maxillary defect with a two‐step preliminary impression. An elastomeric material ball is first placed in the defect until full setting. Then, this “obturator bulb” is removed and eventually relined until it is retentive. Retentions are designed on the oral side of the bulb and the bulb is placed back into the defect. Finally, an alginate over‐impression of the maxillary is made. The alginate is removed after full setting, and the obturator can be reassembled on the maxillary impression to provide a full recording of the maxillary. This protocol can safely be used for defects of any size, despite eventual limitations in oral opening.

AbstractBackgroundChoristomas consist of the proliferation of normal cells or tissue in an abnormal location. Oral choristomas are considered very rare.AimsThe present study aims to report a case of dorsal tongue surface cartilaginous choristoma, with emphasis on its clinical and histopathological features.Case ReportA 72‐year‐old woman attended a dental office with a chief complaint of a persistent tongue lesion. The patient reported that the lesion grew slowly for about 3 months, with no trauma history in the region. An intraoral examination revealed a nodular lesion on the dorsal tongue surface, normal mucosa coloration, firm consistency and sessile implantation, measuring approximately 1.5 cm in diameter. Based on the clinical examination, a diagnosis hypothesis of a granular cell tumour was considered, and an excisional biopsy was performed for confirmation. Given the microscopic findings, the histopathological diagnosis confirmed a cartilaginous choristoma. The patient has been under follow‐up for 12 months, with no signs of relapse.ConclusionThis case highlights the importance of clinical and histopathological findings for the correct diagnosis and treatment of oral choristoma.
Sexuality, romantic orientation, and masculinity: Men as underrepresented in asexual and aromantic communities
Authors: Tessler Hannah , Winer Canton 
Published: September 2023

AbstractThis study examines men as a minority in asexual (experiencing low/no sexual attraction) and aromantic (experiencing low/no romantic attraction) communities. First, we situate our research in existing literature on asexuality, compulsory sexuality/compulsory romance, and hegemonic masculinities. In our analysis, we use survey data from the 2020 Asexual Community Survey (n = 4974) and 2020 Aromantic Census (n = 3018) to provide evidence that asexual and aromantic men are demographic minorities within asexual and aromantic communities. Next, we turn to two interview samples with 39 individuals who identify as aromantic and 77 individuals who identify as asexual. We analyzed these interviews to explore how sexuality and romance contribute to the construction of hegemonic masculinities. Our interviews reveal several important themes that highlight how asexual and aromantic men navigate their masculinity and identity amid asexual and aromantic communities as majority‐woman spaces. We focus on three main themes: (1) masculinity as inherently sexual; (2) masculinity, heteronormativity, and the gendered construction of romance; and (3) asexual/aromantic identity, masculinity, and the split attraction model. Taken together, our results show how (hetero)sexuality and romantic relationship formation are fundamental to hegemonic masculinity. We find that asexual and aromantic men face cultural pressures and social stigma around initiating sex and performing romance. Asexual men must contend with managing a sexual identity that runs counter to men's supposedly innate sexual desire, thus situating them as inadequately masculine. Aromantic men, meanwhile, must manage inhabiting an identity that is conflated with the fuckboy/player trope, situating them as excessively masculine. This study demonstrates how centering asexual and aromantic perspectives reveals complexities in the ways hegemonic masculinity relies on participation in both sex and romance. We conclude by relating our findings to larger conversations on gender and sexualities as well as implications for future research on marginalized sexual identities.

Published: September 2023

AbstractThis paper shows that the group is boundedly elementary generated for and the ring of algebraic integers in a global function field. Contrary to previous statements for number fields and earlier statements for global function fields, the bounds proven in this paper for elementary bounded generation are independent of the underlying global function field and only depend on the integer . Combining our main result with earlier results, we further establish that elementary bounded generation always has bounds independent from the global field in question, only depending on .
Effect of melatonin in patients with low anterior resection syndrome (MELLARS): a study protocol for a randomised, placebo-controlled, crossover trial

Published: September 2023

IntroductionAfter rectal cancer surgery, a majority of patients suffer from sequelae known as low anterior resection syndrome (LARS). It is a collection of symptoms consisting of flatus and/or stool incontinence, evacuation frequency, re-evacuation and urgency. The circadian hormone, melatonin, has shown to possess anti-inflammatory properties, and in high doses, it reduces bowel movements. The aim of the study is to investigate if locally administered melatonin has an alleviating effect on LARS. Secondarily, the effect of melatonin on bowel movements, other patient-reported symptoms, quality of life, depression, anxiety, sleep disturbances, motilin levels and rectal mucosa histology will be examined.Methods and analysisThis is a randomised, placebo-controlled, double-blinded, two-period crossover trial. The participants are randomised to 28 days of 25 mg melatonin administered rectally via an enema daily (or placebo) followed by a 28-day washout and then 28 days of placebo (or melatonin). Three participants will be included in an internal feasibility test. They will receive 25 mg of melatonin daily for 28 days. Data from these participants will be used to assess the feasibility of the rectally administered melatonin and to analyse the course of recruitment and outcome measurements. Afterwards, 18 participants will be included in the crossover trial. The severity of the LARS symptoms will be evaluated using the LARS Score on the first and last day of each treatment period.Ethics and disseminationThe Regional Ethics Committee, the Danish Medicines Agency and the Data and Development Support in Region Zealand approved this study. The study will be performed according to the Helsinki II declaration. Written informed consent will be obtained from all participants. The results of the study will be submitted to peer-reviewed journals for publication and presented at congresses.Trial registration numbersEudraCT Registry (2020-004442-11) and ClinicalTrial.gov Registry (NCT05042700).
Is extending eligibility for adult social care better than investing more in existing users in England? A cross-sectional evidence for multiple financial years
Authors: Longo Francesco , Claxton Karl , Lomas James , Martin Stephen 
Published: September 2023

ObjectivesPublicly funded adult social care (ASC) in England aims to improve quality of life through the provision of services for individuals with care needs due to physical and/or mental impairment or illness. Access to these services, however, is often restricted to contain public expenditure. With a fast-growing care need, information on whether extending eligibility is good value for money becomes policy-relevant.Primary and secondary outcome measuresThis study investigates the effect of extending ASC eligibility on user care-related quality of life (CRQoL), a policy-relevant measure of quality of life.DesignWe use English cross-sectional survey data from 2017/2018 to 2019/2020 on users receiving publicly funded long-term support including domiciliary and other community-based social care, as well as residential and nursing care from local authorities responsible for ASC. We employ the two-stage least square method to estimate the impact of ASC expenditure on CRQoL at various levels of ASC expenditure in each financial year. This includes the CRQoL effect of increasing expenditure from zero to some level, which captures the effect of extending ASC eligibility to new users.ResultsWe find that publicly funded ASC improves the CRQoL of both existing and newly eligible users, although the latter are likely to experience greater CRQoL gains. Moreover, from 2017/2018 to 2019/2020, spending as much as an average user for a newly eligible user costs between £54 224 and £77 778 per social care-quality-adjusted life year (SC-QALY) gained. These results are statistically significant at the 5% level. Compared with this finding, increasing expenditure for an existing user has always a higher cost per SC-QALY gained.ConclusionsExtending ASC eligibility to new users is likely to be more cost-effective compared with using the same resources to increase expenditure for existing users.
Protocol for a qualitative study exploring the pharmacist’s role in supporting postsecondary students with psychotropic medication management
Authors: McCracken Andrea , Cleverley Kristin , Sproule Beth A , Dolovich Lisa 
Published: September 2023

IntroductionFindings from the National College Health Assessment (2019) stated that anxiety and depression are the most prevalent diagnosed mental illnesses among Canadian postsecondary students with one-fifth of students self-reporting a lifetime diagnosis. Psychotropic medications can be an important component of a multifaceted approach to the management and treatment of mental illness and are the most commonly dispensed via community pharmacies. Community pharmacies provide an opportunity for pharmacists to have a prominent role in supporting patients’ psychotropic medication management. However, there has been limited exploration of how pharmacists can address patients’ psychotropic medication management needs, experiences and opportunities for improvements especially for emerging adults.Methods and analysisThis qualitative study will incorporate Thorne’s approach to interpretative description. Purposeful snowball sampling will be used to identify students (18–25 years) taking psychotropic medication(s) to manage their mental health. Participants will be interviewed one on one using a semistructured interview guide virtually. Inductive thematic analysis is underway with data analysis being iterative and reflexive using NVivo. Information provided from the interviews will be reviewed and summarised into key themes.Ethics and disseminationThis study was approved by the University of Toronto Health Sciences Research Ethics Board (REB #43185). It is expected that there will be a very low risk for mild psychological and social harm for participants as they will have the ability to stop the interview at any time and will be aware of confidentiality. The results from this study will be used to create or adapt healthcare team services including the role of pharmacists within the healthcare ecosystem at the university and contribute to developing the next stage of research to evaluate feasibility and effectiveness of programmes at the university that help postsecondary students to manage psychotropic medication.

Published: September 2023

BackgroundChronic non-cancer pain (CNCP) treatment’s primary goal is to maintain physical and mental functioning while improving quality of life. Opioid use in CNCP patients has increased in recent years, and non-pharmacological interventions such as music listening have been proposed to counter it. Unlike other auditive stimuli, music can activate emotional-regulating and reward-regulating circuits, making it a potential tool to modulate attentional processes and regulate mood. This study’s primary objective is to provide the first evidence on the distinct (separate) effects of music listening as a coadjuvant maintenance analgesic treatment in CNCP patients undergoing opioid analgesia.Methods and analysisThis will be a single-centre, phase II, open-label, parallel-group, proof-of-concept randomised clinical trial with CNCP patients under a minimum 4-week regular opioid treatment. We plan to include 70 consecutive patients, which will be randomised (1:1) to either the experimental group (active music listening) or the control group (active audiobooks listening). During 28 days, both groups will listen daily (for at least 30 min and up to 1 hour) to preset playlists tailored to individual preferences.Pain intensity scores at each visit, the changes (differences) from baseline and the proportions of responders according to various definitions based on pain intensity differences will be described and compared between study arms. We will apply longitudinal data assessment methods (mixed generalised linear models) taking the patient as a cluster to assess and compare the endpoints’ evolution. We will also use the mediation analysis framework to adjust for the effects of additional therapeutic measures and obtain estimates of effect with a causal interpretation.Ethics and disseminationThe study protocol has been reviewed, and ethics approval has been obtained from the Bellvitge University Hospital Institutional Review Board, L’Hospitalet de Llobregat, Barcelona, Spain. The results from this study will be actively disseminated through manuscript publications and conference presentations.Trial registration numberNCT05726266.
Exploring conduction mechanisms in chalcogenide thin films: an experimental and soft computing approach with ANN and GP techniques
Authors: Habashy D. M. , Atyia H. E. , Lebda H. I. 
Published: September 2023

AbstractThe article consists of two main sections. In the first part, an experimental study was conducted to investigate the AC conduction of Se83Bi17 (SB), Se83Bi17Ge5 (SBG), and Se83Bi17Te5 (SBT) in thin film forms. Thermal evaporation was utilized to produce films with different thicknesses. The measurements were performed at temperatures ranging from 293 to 393K, film thicknesses ranging from 230.2 to 543.9 nm, and frequencies ranging from 0.1 to 1000 kHz. The AC data were analyzed using the frequency power law. The values of the frequency exponent and their temperature dependence confirmed that the conduction process in the thin films is governed by the hopping mechanism. Additionally, the impact of introducing Te and Ge on the studied properties was also investigated in this study. The second section of the article focuses on estimating the AC conduction of Se83Bi17 (SB), Se83Bi17Ge5 (SBG), and Se83Bi17Te5 (SBT) films using Artificial Neural Networks (ANNs) and Genetic Programming (GP). The experimental data was employed as inputs for training the ANNs and the GP models. The simulation and prediction results obtained from both models were compared with the experimental data and reported. Equations were developed to describe the behavior of the experimental data. The study concluded that the ANN approach is more suitable for simulating and forecasting AC conductivity.

Published: September 2023

In this issue I want to spotlight two important new releases. Jeff Shallit's The Logical Approach to Automatic Sequences introduces the software Walnut for deciding first-order statements in Buchi arithmetic. This software has been used to prove hundreds of results in combinatorics on words. Can the junior's dream of replacing the pumping lemma with a similar software be far behind? Data Science in Context is a new textbook by Alfred Spector, Peter Norvig, Chris Wiggins and Jeannette Wing that addresses the breadth, oppportunities and perils of the field. Its new feature is a sevenelement analysis rubric for determining data science's applicability to a proposed application.

Gosto musical, moral e incômodos
Authors: Trotta Felipe da Costa 
Published: September 2023

A música é uma forma de ação e pensamento no mundo. Participar de uma experiência musical é interagir com ideias, valores e pertencimentos que por vezes se afastam de nossas predileções, outras vezes se aproximam. O gosto musical é um eixo importante de debates sobre as experiências musicais cotidianas. A partir de uma pesquisa sobre incômodos musicais, proponho aqui uma reflexão sobre o gosto não a partir de movimentos de adesão, mas de rechaço. Foram realizadas mais de 70 entrevistas com indivíduos de distintas faixas etárias, classes sociais e regiões do planeta, nas quais indagamos sobre situações em que a música agiu como elemento de incômodo. Ao classificar uma música como incômoda ou desagradável, as pessoas elaboram códigos morais, aprofundando interpretações sobre ética e comportamentos que partem do julgamento sonoro e se ampliam em um julgamento mais amplo sobre os indivíduos e os valores reconhecidos nas músicas.
Pensar lo popular desde un lugar otro: La propuesta de Jesús Martín-Barbero y su aporte al debate teórico sobre la cultura popular
Authors: Parducci Amparo Marroquín 
Published: September 2023

Jesús Martín-Barbero ha sido un referente latinoamericano en los estudios de comunicación y cultura. Su trabajo permitió colocar en el debate una mirada histórica y un mapa conceptual de los referentes y disputas en torno a lo popular. La hipótesis de este trabajo es que Martín-Barbero consiguió, y ese fue su mayor aporte, desplazar el lugar de lo popular desde lo ancestral/originario hasta un lugar más plebeyo, más bastardo, más sospechoso y más anclado con la realidad latinoamericana de su momento: colocó lo popular cerca del mundo masivo. El presente texto retoma elementos elaborados en la tesis doctoral y, a partir de ello, recupera dos reflexiones centrales sobre la cultura popular en el pensamiento de Martín-Barbero: la mirada histórica y genealógica sobre lo popular, que este autor trabajó en su libro De los medios a las mediaciones, y su desplazamiento hacia el lugar de lo masivo y las implicaciones que esto tiene, que también se desarrolla con extensión en la misma publicación, a partir de lo cual se ofrecen algunas conclusiones.
Effect of residence time in the reactor on the reinforcement of biochar in rubber compounds
Authors: Ribeiro Willian B. , Godinho Marcelo , Brandalise Rosmary N. 
Published: September 2023

In the present work, the effect of residence time on the production of biochar by the pyrolysis process of Pinus spp. was investigated. Biochar was produced at three different residence times in the reactor (30, 60, and 240 min). The effect of residence time on the load in the pyrolysis process was evaluated based on the rheometric, physical and mechanical properties of the elastomeric compounds. The shortest residence time, 30 min, produced a biochar with a graphitic structure (turbostratic) that was ideal for the interaction between load and elastomer and caused the least possible disturbance to the crystallization process by stretching the natural rubber, which was observed from the tensile strength, while maintaining the mechanical properties. As the residence time increased, it was observed that the more crystalline structure interfered with the crystallization process of the natural rubber when stretched, causing a decrease in tensile strength and decreasing the interaction between the load- elastomer, thus increasing the vulcanization time of the rubber. The compound was prepared using the filler with the longest residence time (NR/BIO240min).
