A lepton model with nearly Cobimaximal mixing
Authors: Gómez Juan Carlos , Pozas Ramírez Asahel Enrique
Published: July 2024

Cobimaximal mixing predicts π/4 and 3π/2 for the atmospheric angle and the Dirac CP-violating phase, respectively. These values are in tension with the neutrino global fits. If this pattern was behind the lepton mixings, then it would have to be broken. In that case, in this paper, we explore the S3 flavor symmetry within the B − L gauge model where the aforementioned scheme comes from the neutrino sector but the charged lepton contribution breaks the well known predictions so the mixing observables as well as the mee mass can be accommodated quite well according to the available data. Notably, the predicted regions for the Dirac CP-violating phase would allow us to test the model in future experiments.

Published: July 2024

Partiendo de la teoría de masa efectiva y el modelo de Thomas-Fermi (TF) se ha establecidoel perfil de potencial para un sistema tipo delta-dopado simple en Arseniuro de Galio(GaAs) tipo n. Resolviendo la ecuación de Schrödinger asociada al sistema, se han calculadolos autovalores y las autofunciones del perfil de potencial, determinando así su estructura electrónica.Con ayuda de la teoría de Matriz Densidad se ha determinado el cambio en el índicede refracción (CIR) lineal y no lineal del sistema. De tal manera que, añadiendo un término dedesorden en el sistema (ζ), es posible calcular numéricamente los cambios en la estructura electrónicay las propiedades ópticas no lineales. Se ha determinado que con valores de ζ alrededordel 10% asociado a la densidad de impurezas (N2D), el cambio en el índice de refracción linealy no lineal no sufre cambios significativos. Por otro lado, cuando se incrementa el desorden enla densidad de impurezas introducidas en el material semiconductor, el comportamiento de lapropiedad óptica se pierde por completo. Finalmente, notamos que al introducir desorden enla intensidad del laser, la propiedad óptica no sufre cambios. El presente estudio teórico podríapredecir el efecto del desorden estructural sobre el comportamiento del CIR en los dispositivosbasados en delta dopados al momento de su síntesis.
Numerical investigation into the Nd doped YAG rod grooving impact on the sunlight-pumped-laser performance
Authors: SAID MEHELLOU , Hamrouni Noureddine , Ferhat Rehouma
Published: July 2024

This paper presents a numerical analysis of the impact of grooving the Nd doped YAG rod on the sunlight-pumped lasers performance. The study analyzes laser systems that utilize side-exciting and end-side-exciting approaches to activate both grooved and non-grooved Nd doped YAG laser rods. The effects of the rod surface groove on the performance of the sunlight-pumped-lasers are thoroughly examined using ZEMAX© and LASCAD© software. To excite the grooved and non-grooved Nd doped YAG rods alternately, a ring-array sunlight flux concentrator is employed. Moreover, in the side-exciting technique, the head of the laser system contains a rectangular light guide of an extremely transparent glass made from fusing silica and an excitation cavity with a V-shaped configuration, housing the Nd doped YAG rod. This exciting method with a grooved laser rod resulted in a 13.70% increase in laser power and a 28.20% reduction in stress intensity compared to the non-grooved rod. In the end-side-exciting technique, the head of the laser system comprises an aspheric lens made of a fused silica glass and a conical-shaped excitation cavity, accommodating the Nd doped YAG rod. Results indicate that using grooved laser rod in this exciting system did not lead to an amelioration in output laser power. However, this technique enhanced the stress intensity by a reduction of 35.03%.
DFT formalism studies on the structural and electronic properties of hexagonal graphene quantum dot with B, N and Si substitutional impurities
Authors: Méndez Martínez K. M. , Nava Maldonado Flavio Manuel
Published: July 2024

The study of carbon-based nanostructured materials is a highly active research field, that has made significant progress in the study of twodimensional materials and nanotechnology. The interest in these materials is mainly attributed to the fascinating properties they exhibit, as seen in the case of graphene as a 2D material, as well as emergence on numerous novel 2D materials and their heterostructures. Additionally, there is important interest in systems such as 2D quantum dots. Therefore, this work focuses on the systematic study of graphene quantum dots of various sizes, all within the framework of first-principles density functional theory. We started with the simplest graphene quantum dot (GQD) structure, benzene (C6H6), which consist of six carbon atoms passivated with hydrogen atoms. We then increased its size by adding more aromatic rings, resulting in the following GQD configurations: C24H12, C54H18, C96H24, C150H30 and C216H36. We report the density of states (DOS) and the imaginary part of the dielectric function (ε2) for the system, analyzing both the pristine configuration and the effect of both single and double (boron, nitrogen and silicon, denoted as Sa). The double substitutional atom study was done considering random, ortho-, meta-, and para-director positions just for the C94H24Sa2 GQD. In general, we can conclude that as the GQD increases in size, the HOMO-LUMO energy decreases. Furthermore, it is observed that boron and nitrogen exhibit their expected n-, and p-type doping characteristics, but this differs between single and double Sa substitutions. Additionally, the imaginary part of the dielectric function is highly sensitive to the positions of single and double substitutional atoms, as well as the polarization of incident light. Therefore, we suggest that these differences can be used to clearly determinate the type of substitutional atoms and their positions from optical measurements.

Authors: Telesnicki Teagan T. , Simpson Andrea N. , de Mestral Charles , Baxter Nancy N. , Urbach David R. , Gomez David
Published: July 2024

Purpose:

The COVID-19 pandemic has resulted in a significant diagnostic, screening, and procedure backlog in Ontario. Engagement of key stakeholders in healthcare leadership positions is urgently needed to inform a comprehensive provincial recovery strategy.

Methods:

A list of 20 policy recommendations addressing the diagnostic, screening and procedure backlog in Ontario were transformed into a national online survey. Policy recommendations were rated on a 7-point Likert scale (strongly agree to strongly disagree) and organized into those retained (≥75% strongly agree to somewhat agree), discarded (≥80% somewhat disagree to strongly disagree), and no consensus reached. Survey participants included a diverse sample of healthcare leaders with the potential to impact policy reform.

Results:

Of 56 healthcare leaders invited to participate, there were 34 unique responses (61% response rate). Participants were from diverse clinical backgrounds, including surgical subspecialties, medicine, nursing, and healthcare administration and held institutional or provincial leadership positions. A total of 11 of 20 policy recommendations reached the threshold for consensus agreement with the remaining 9 having no consensus reached.

Conclusion:

Consensus agreement was reached among Canadian healthcare leaders on 11 policy recommendations to address the diagnostic, screening, and procedure backlog in Ontario. Recommendations included strategies to address patient information needs on expected wait times, expand health and human resource capacity, and streamline efficiencies to increase operating room output. No consensus was reached on the optimal funding strategy within the public system in Ontario or the appropriateness of implementing private funding models.

Authors: Luigi Mimosa , Yin Charles , Misaghi Ehsan , Lao Robert X. , Bogie Bryce J. M. , Macklin Jillian , Zeng Andy , Jones Nicola
Published: July 2024

Purpose:

Despite the impact of physician-scientists on scientific discovery and translational medicine, several reports have signalled their declining workforce, reduced funding, and insufficient protected research time. Given the paucity of outcome data on Canadian MD/PhD programs, this study presents a national portrait of the sociodemographic characteristics, training trajectories, productivity, and satisfaction in trainees and alumni from Canadian MD/PhD and MD/MSc programs.

Methods:

Quantitative data were collected in a national survey launched in 2021. Respondents included 74 MD/PhD alumni and 121 trainees across 12 Canadian MD/PhD and MD/MSc programs.

Results:

Among MD/PhD alumni, 51% were independent practitioners/researchers while others underwent residency training. Most trainees (88%) were in MD/PhD programs. Significantly more alumni identified as men than did trainees. Significantly more alumni conducted clinical and health services research, while more trainees conducted basic science research. Average time to MD/PhD completion was 8 years, with no correlation to subsequent research outcomes. Self-reported research productivity was highest during MD/PhD training. Concerning training trajectories, most alumni completed residency, pursued additional training, and practised in Canada. Finally, regression models showed that trainees and alumni were satisfied with programs, with significant moderators in trainee models.

Conclusion:

Survey findings showed Canadian MD/PhD and MD/MSc programs recruit more diverse cohorts of trainees than before, provide productive research years, and graduate alumni who pursue training and academic employment in Canada. Both alumni and trainees are largely satisfied with these training programs. The need to collect in-depth longitudinal data on Canadian MD/PhD graduates to monitor diversity and success metrics is discussed.
A Monstrous Growth: The Experimentation and Afterlives of Caragana Arborescens
Authors: Stewart Haeden
Published: July 2024

This paper traces the history of Caragana arborescens, a shrub which has flourished for a hundred years in the polluted industrial landscape of Mill Creek Ravine, Edmonton. While now considered an invasive plant, caragana was once viewed as a vitally important species in the colonial settlement and transformation of the Canadian prairies. Arguing against the view of caragana as simply an extension of settler colonialism, or as an embodiment of industrial abandonment, I posit that caragana can be better thought of as a monstrous disturbance: a dense node of bodies and historical relations which emerged out of an experimental colonial project and thrives in the degraded landscapes that industrial capitalism has wrought. As a monstrous disturbance, caragana’s growth recollects, extends, and troubles the experimental colonial project that brought it to Mill Creek Ravine.
Cold War “Cultural Safaris”: Canadian Art, Cultural Diplomacy, and the Asian Commonwealth Tour
Authors: Brison Jeffrey , Jessup Lynda
Published: July 2024

In 1955, the National Gallery of Canada circulated an exhibition of Canadian art to the “Asian commonwealth”—Pakistan, India, and Ceylon (now Sri Lanka). Developed in tandem with Canada’s involvement in the Colombo Plan for Co-operative Economic Development in South and Southeast Asia, the tour was part of a wide-angled strategy of cultural engagement that, despite its humanitarian trappings, was grounded in Cold War politics. Featuring a small display of relatively unimportant works in venues of limited interest to the National Gallery, the tour nonetheless marks a significant juncture in the development of the Canadian cultural state—a turning point in the relationship between the gallery and Canada’s Department of External Affairs, which in the immediate postwar decades sought to coordinate with the National Gallery in pursuit of an active role in the information brokering and cultural work it identified in the gallery’s promotion of Canadian art abroad. In this article, we position the Asian commonwealth tour as a case study that reveals the inherent tension in the relationship between the cultural and policy spheres of the state that informed Cold War mobilization of the liberal values art was thought to express.
Cultural Distinction and the University of Toronto: Constructing Symbolic Boundaries of Social Class in Canada, 1894–1950
Authors: McLean Scott
Published: July 2024

In the first half of the twentieth century, the University of Toronto was a preeminent cultural institution in Canada. Based on a critical interpretation of archival documents, this article narrates the history of four non-formal educational programs through which the University of Toronto created opportunities for Canadians to develop privileged forms of cultural taste and practice: the administration of local examinations in music across Canada, the development of a museum oriented to public visitation, the organization of public lectures in collaboration with local associations across Ontario, and the delivery of non-credit evening courses in Toronto. These four programs engaged hundreds of thousands of Canadians in forms of activity that supported the development of what Bourdieu conceptualized as constellations of cultural distinction: arrays of tastes and practices that mark symbolic boundaries of social class. Two of the programs resulted in national cultural institutions (Royal Conservatory of Music and Royal Ontario Museum) prominent in fields that have been empirically associated with social class boundaries in Canada. The other two programs declined in significance after 1950 and have not previously been included in analyses of cultural distinction. This article explores the historical role of Canadian universities in constructing symbolic boundaries of social class.
Exploring the Interdependence Model in Malaysia-Indonesia Relations: Insights from Sabah, Malaysia
Authors: Dollah Ramli , Maraining Amrullah , Jafar Adi , Joko Eko Prayitno , Sakke Nordin
Published: July 2024

The historical similarities between Malaysia and Indonesia, apparent in geographical proximity and social-cultural dimensions, significantly influence perspectives and discourse on their bilateral relations. Despite frequent assertions of shared kinship and racial ties, relations between Malaysia and Indonesia are consistently characterised by rivalry, marked by numerous disagreements and challenges. This paper posits that conflict is a minor element in the broader discourse of relations, emphasising the importance of cooperation due to the complex interdependence between these two countries. Using Sabah as a case study, this paper highlights the significance of interdependence between Malaysia and Indonesia, delving into pivotal issues that shape the dynamics of their bilateral relationship. It focuses on several issues such as the population and kinship ties, the reliance of the Sabah economic sector on the Indonesian Migrant Workers (PMI), consumer goods and everyday necessities, interdependence in the security sector, and finally haze and environmental pollutions to outline the dynamics of interdependence between Sabah (Malaysia) and Indonesia. All facets describing these relations are emphasised since they demonstrate that these two countries are interdependent and share common interests in nearly all sectors. This paper contends that despite facing various contentious issues and problems, the interdependence that occurs contributes to a harmonious relationship and is able to avoid conflict between the two countries.
A Historical Exploration of the Selected Writing Trends on As-Sīrah An-Nabawiyyah (Prophetic Biography) from the First Century of Islam to the Contemporary Times
Authors: Ashker Aroos  , Fatmir Shehu
Published: July 2024

This research paper seeks to explore trends or tendencies in as-Sīrah an-Nabawiyyah (Prophetic Biography) emphasizing the historical investigation of selected writings on this subject from the first century of Islam until contemporary times. Muslims and others find exemplary qualities in every aspect of the Prophet’s life that inspire them to love him, understand his sayings, and follow his deeds, and accept all his decisions. Also, Muslim scholars rely on the Prophetic Sīrah to understand and explain the Islamic Sources, al-Qur’an and as-Sunnah. Initially, most works on Sīrah focused on the composition of the Prophet’s biography, and subsequently, their writers became interested in recording its events in separate books. This study aims to highlight the writing trends on the Prophetic Sīrah throughout Islamic history, and then, examine selected writings addressing the demands and concerns of their times. This work starts with an introduction, and then, continues the discussion on the literal and technical definition of the Prophetic Sīrah, the phases of its writing trends, firstly, from the first century to the third century, secondly, from the fourth century to the golden age of Orientalism, and, lastly, from nineteenth century to contemporary age. This study arrives at insightful findings that for each age, there has been a trend or tendency in the writing of the Prophetic Sīrah according to the demands and concerns of the time. The researchers propose that the demands of modern-day writing trends on the Prophetic Sīrah include rhetorical (Kalāmī), philosophical (Falsafī), and social (Ijtimā’ī) approaches.

Theoretical and methodological analysis of the state of research on the problem of mental protection of the individual
Authors: Hulbs Olha , Vorona Oleg
Published: July 2024

The article presents a theoretical and methodological analysis of the state of research on the problem of psychological protection of the individual. It is noted that the system of psychological protection is formed in the general structure of personality as a certain combination of protective mechanisms. As a result of the action of defence mechanisms, a specific state of consciousness is formed, which allows the individual to maintain the harmony and balance of it`s structure. Today, most researchers consider mental defence mechanisms to be processes of personal intrapsychic adaptation that occur under the influence of subconscious processing of incoming information.
To date, a great deal of material has been accumulated on this issue, in which the following points can be distinguished. First, it is the complexity of the functioning of defence mechanisms. Individuals rarely use a single defence mechanism - they usually use a complex of defence mechanisms. This complex is specific to each individual and is formed early enough in genesis. Second, there is a positive effect of defence mechanisms on personality development. Defence mechanisms are quite dynamic in themselves: through their development, integration and adaptation of the individual takes place. This is their positive influence on personality formation. Thus, defence mechanisms are widely present both in normal, healthy psychological functioning of the individual and in unhealthy, pathological ones. Their effect can be detected in every person. The third point concerns the function of defence mechanisms. They are used by an individual to relieve or prevent anxiety, to resolve emotional conflicts, to resist emotional discomfort, to prevent a return to thoughts, emotions, desires, fantasies that have previously been pushed out of consciousness because of their painfulness and unacceptability. Fourthly, mental regulation in difficult situations for the subject with the help of defence mechanisms usually occurs at the unconscious level.
Socio-psychological characteristics of students
Authors: Dikhtyarenko Svitlana , Remeniuk Yana
Published: July 2024

The article reveals the socio-psychological features of student age. It is noted that the main psychological formations of personality at this stage of formation are independence, social maturity and activity, the desire for self-knowledge, self-development and self-realisation (self-realisation), harmonisation of the "I" system, the presence of generalised methods of cognitive and professional activity, structured intelligence in combination with intellectual potential, professionalisation of knowledge, skills and abilities, formation of a base of socio-professional skills.
The leading features of students include: social orientation of thinking (social intelligence), active life (position), high level of empathy, and affiliation. In the individual-personal and professional aspects, the stable characteristics of a psychologist include: nervous system lability; mixed choleric-sanguine type of temperament; pronounced extraversion; pronounced social orientation; intuitive-sensitive type of temperament; acceptance of other people and values; direct worldview; focus on effective implementation in the profession; high social control of behaviour; self-actualisation as a guide for self-development. Negative qualities that hinder or complicate professionalisation include: increased neuroticism; low level of trust in people, belief in their goodwill and sincerity; inability to establish strong and friendly relationships with others; desire for power, domination and manipulation; focus on solving one's own problems; dissonance between theoretical and personal values. However, overcoming these negative tendencies can become a driving force in the self-development of a future psychologist.
The influence of internal personal conflicts on the formation of personality in adolescent age
Authors: Stanishevska Viktoriia
Published: July 2024

The article examines and analyzes modern and foreign research on the influence of intrapersonal conflicts on personality formation in adolescence. The factors that contribute to the emergence of intrapersonal conflicts, including physiological changes, social pressure and the search for self-identity, are analyzed. The positive and negative effects of intrapersonal conflicts on the formation of a teenager's personality are determined. Insufficient understanding of the nature and consequences of intrapersonal conflicts in adolescence makes it difficult to develop effective strategies to support young people. Internal conflicts in adolescence are usually associated with contradictions between the desire for independence and the need for support, the search for one's own identity and pressure from peers and society, as well as with changes in physiological development. These conflicts can lead to emotional stress, increased anxiety, depression and other mental disorders. Effective overcoming of such conflicts contributes to the formation of a healthy, mature and stable personality.
Russia's full-scale invasion of Ukraine and hostilities have a profound effect on the psychological state of teenagers. War creates a constant state of danger, uncertainty, and stress that exacerbates intrapersonal conflicts. Adolescents who live in a war zone or have lost loved ones face additional emotional and mental challenges. Intrapersonal conflicts in adolescence are an inevitable part of the growing up process and have a significant impact on personality formation.
 This emphasizes the need to conduct a comprehensive study aimed at studying specific aspects of the influence of these conflicts on the formation of the personality of teenagers in the conditions of modern Ukraine. The results of such a study can become the basis for the development of recommendations for psychologists, teachers and parents on supporting adolescents in overcoming internal contradictions and promoting their positive development.

Aim. To compare the microbiome of the healthy gingival sulcus of children with bronchial asthma (BA) and different dental conditions. Design. Open comparative clinical and laboratory study. Materials and methods. Gingival substrate was obtained from 19 children aged 3–6 years with exacerbation of BA; the results of sequencing the genes of 16 subunits of ribosomal ribonucleic acid (16S rRNA) on the MiSeq platform (Illumina) were analyzed. Results. Five major phyla have been identified in the gingival sulcus: Firmicutes, Proteobacteria, Actinobacteria, Fusobacterium and Bacteroidetes and the dominant genus, Streptococcus. A significantly high relative prevalence of the species Neisseria oralis (p = 0.0073), Hemophilic massiliensis (p = 0.046), Hemophilic paraphrohaemolyticus (p = 0.05) and Lautropia mirabilis (p = 0.05) in children with asthma without caries was established. The level of immunoglobulin E (IgE) is significantly higher in children with asthma and caries compared to children without caries (461.79 ± 60.58 and 276.97 ± 81.15 IU/ml). Conclusion. The predominance of opportunistic and “healthy” bacterial species of the phylum Proteobacteria in the healthy gingival sulcus of children with BA may be an indicator of oral dysbiosis in BA. Overproduction of IgE in children with caries may be due to cariogenic flora, which requires further study. Keywords: sequencing, gingival crevicular microbiome, children, bronchial asthma, caries.

Relevance of the research topic. A specialist will be able to compete effectively on the labor market only when he is ready for a specific type of activity and will have a sufficient supply of reserve capabilities of the body. Studying the ways of psychoregulation and increasing the level of development of psychophysiological abilities of students is an important problem of the organization of physical education in higher education institutions. The purpose of the research is to experimentally substantiate the effectiveness of the use of means from sports games on the development of psychophysiological abilities of students. Research methods: analysis and generalization of scientific and methodical literature, dynamometry, spatial orientation test, computer program "Psychodiagnostics", methods of mathematical statistics. Research results. During the year, a set of specific exercises aimed at the development of psychophysiological abilities was implemented in the training of students of optional groups in sports games. In order to determine the differences in the impact of various sports in the pedagogical study, optional control groups from power sports and athletics were selected. The indicators of muscle differentiation, spatial orientation, simple visual-motor reaction and reactions of distinction and choice were studied. In the experimental groups, an increase was obtained in all the mentioned tests, but it differed both in terms of indicators and in different game sports, which corresponded to the features of competitive activity. In the control groups, according to some indicators, there were also positive shifts in the development of psychophysiological abilities, but they were not statistically reliable. Conclusions. The specifics of the impact of various sports on students' muscular, spatial sensations and psychomotor skills have been determined. The developed complexes of special means for sports games have shown their effectiveness and can be recommended for their use in the physical education of students for a purposeful effect on psychophysiological abilities.

OBJECTIVE

In the United States, more than 1 million sport-related concussions afflict children annually, with many cases undetected or unreported. The Sport Concussion Assessment Tool (SCAT) is widely used to detect concussions in high school, collegiate, and professional sports. The objective of this study was to establish baseline values for the SCAT version 5 (SCAT5) in high school athletes.

METHODS

Baseline SCAT5 evaluations were conducted in students (ages 14–19 years) from 19 high schools in central Illinois who were participating in various school-sponsored sports. The SCAT5 evaluations were retrospectively extracted from the electronic medical record system for analysis. Statistical analyses included the Wilcoxon rank-sum test for continuous variables and the chi-square test for categorical variables, considering significance at p < 0.05. Test-retest reliability at < 6 months, 10–14 months, and 16–20 months was computed using intraclass correlation and Spearman’s rho (ρ). Reliable change indices are provided using the Iverson formula.

RESULTS

A total of 2833 unique athletes were included, and the average age was 15.5 ± 1.14 (SD) years. There were 721 female (25.5%) and 2112 male (74.5%) athletes. Students ≥ 15 years old had more prior concussions (p < 0.001), and male athletes were more frequently hospitalized for head injury (p = 0.013). Female athletes exhibited a significantly higher prevalence of mood disorders (14.7% vs 4.6%, p < 0.001), whereas attention-deficit/hyperactivity disorder was more common in male athletes (5.2% vs 13.2%, p < 0.001). Symptom number and severity were significantly greater in female athletes (3.17 ± 4.39 vs 2.08 ± 3.49, p < 0.001; 5.47 ± 9.21 vs 3.52 ± 7.26, p < 0.001, respectively), with mood-related symptoms representing the largest differences. Female athletes and students ≥ 15 years old performed better on most cognitive assessments. Female athletes and students < 15 years old performed better on the modified Balance Error Scoring System (p < 0.001). Test-retest reliability was poor to moderate for most assessment components. Reliable change index cutoff values differed slightly by sex, with female athletes often having a greater cutoff value.

CONCLUSIONS

This study underscores the variability of SCAT5 baseline values influenced by age, sex, and medical history among adolescent athletes. It provides a robust dataset, delineating baseline values stratified by sex and age within this demographic. Additionally, the results provide enhanced guidance to clinicians for interpretation of change and reliability of baselines.

Published: July 2024

OBJECTIVE

Postconcussive symptom questionnaires (PCSQs) are often used in concussion patient assessment, yet there is a lack of knowledge as to whether symptom subtype prevalence is dependent on the mechanism of injury (MOI). These subtypes can be defined as cognitive, atlanto-occipital/cervical spine, autonomic, balance, low energy/fatigue/sleep, emotional changes, eyes, and somatic. Using an institutional PCSQ that quantitatively addressed these subtypes, this retrospective study aimed to provide insight into differences in subtype symptomatology between sports-related (SR) and non–sports-related (NSR) injuries.

METHODS

Consecutive concussion patients with Glasgow Coma Scale (GCS) score ≥ 13 and ≥ 16 years of age who were treated at a concussion clinic affiliated with an academic level I trauma center in the United States between December 2009 and January 2020 were eligible for inclusion. The authors extracted data on MOI, comorbidities, habits, prior injuries, and PCSQ results. Multivariate analysis of covariance was then conducted to determine the correlations between subtype scores and MOI while considering covariates.

RESULTS

Of the 194 patients remaining after applying inclusion and exclusion criteria, analysis included 91 patients in the SR group consisting of 54 (59%) males with mean ± SD (range) age of 20.9 ± 7.3 (16–58) years and 103 patients in the NSR group consisting of 38 (37%) males with mean age of 39.2 ± 14.8 (17–71) years. Demographic characteristics differed significantly between groups. Estimated marginal mean scores were significantly lower in the SR injury group compared to the NSR injury group (with comparing main effects) for the cognitive (p < 0.001), autonomic (p < 0.000), balance (p < 0.025), energy (p < 0.006), emotional (p < 0.000), and total score (p < 0.001) subtypes. Multivariate tests identified three comorbidities that contributed to differences in subtype scores between groups: migraines (p < 0.012), vertigo (p < 0.004), and anxiety (p < 0.038). No significant results were found for the remaining comorbidities of (but not limited to) depression, neuropsychiatric disorders, seizures, syncope, sleep disorder, or none.

CONCLUSIONS

The findings indicate that patients who sustain a concussion via an NSR injury present with more severe symptoms but similar concussion subtype frequency as those presenting with SR concussion. This suggests that the MOI may correlate more closely to symptom severity than concussion subtype composition, although larger patient populations with more definitive control of MOI are needed to further elucidate these claims.
Hemispheric surgery in children: perisylvian technique
Authors: Machado Helio Rubens , Volpon Santos Marcelo
Published: July 2024

Hemispheric epilepsy is quite frequent in children, compared with adults, and encompasses pathological substrates as diverse as hemimegalencephaly, Rasmussen encephalitis, Sturge-Weber syndrome, and porencephaly, among others. These patients most often become pharmacoresistant and thus require surgical management. Although anatomical hemispherectomy is a possibility, the technique that is favored by most epilepsy surgery centers worldwide is functional hemispherotomy, which results in equivalent outcomes with fewer postoperative complications. Therefore, it is essential that pediatric epilepsy neurosurgeons become familiar with these techniques. The present video describes in detail all surgical aspects of the perisylvian hemispherotomy.

Published: July 2024

With the rapid advancement of health delivery, there has been a renewed interest in conducting research among healthcare professionals in Nepal. However, concern is there regarding availability of funds and mechanisms of awarding.  The purpose of this scoping review is to map the available evidence regarding the evolution and current status of health research funding in Nepal and to highlight gaps and areas for future research. We searched three databases for empirical papers and several gray literature. Our search, conducted between March and April 2024 yielded 76 documents of which 30 that met the selection criteria were included in the scoping review. Almost all studies identified lack of funding as a deterrent to research. We found a paucity of research focusing on the role of researchers in funding decision-making. Our findings revealed that there are 12 national and four international organizations providing funds for research. University Grant Commission is the largest funder from Nepal whereas the Research Council of Norway is the biggest international funder. There were certain barriers and facilitators for obtaining funds identified by this scoping review.  Further efforts are needed to increase the amount and availability of funds in Nepal to enable high-quality research.
Duszpasterstwo wojskowe na obszarze diecezji chełmińskiej w latach 1850-1873

Artykuł jest poświęcony duszpasterstwu garnizonowemu na obszarze diecezji chełmińskiej w latach 1850-1873, czyli w okresie jej przynależności do państwa pruskiego. Ze względu na niekwestionowane znaczenie armii pruskiej w utrwalaniu bezpieczeństwa i stabilności państwa, zagwarantowanie udziału w życiu religijnym należało do istotnych czynników formacji wojskowej. Z tego względu stałą opieką pastoralną objęto miasta garnizonowe, do których należały m.in. Gdańsk, Grudziądz i Toruń. Żołnierze stacjonujący w jednostkach wojskowych usytuowanych na obszarze diaspory katolickiej, czyli m.in. w Iławie, Ostródzie, Prabutach, Suszu i Zalewie, również mieli możliwość korzystania z sakramentów dzięki posłudze zamiejscowych kapelanów. Opiekę duchową nad żołnierzami sprawowali przeważnie księża z parafii cywilnych. Dość sporadycznie w tym czasie zatrudniano w diecezji chełmińskiej etatowych kapelanów armii pruskiej.
