Paths shared between people (Homo sapiens sapiens) and dogs (Canis familiaris): from aid therapy partners to friends and family members
Authors: Moreira Maria João , Costa Susana , Casanova Catarina
Published: June 2024

Dogs (Canis familiaris) were the first domesticated species and today, they still have a central role in our societies. Integrated in the post-humanistic approach, we aimed to understand the evolution of the different social roles assumed by dogs, specifically, aid therapy dogs (ATD) that warn human diabetics of the changes that occur in their blood glycemia.  Our main objective was to see if at some point in these shared paths, ATD would start being seen in a different way by their tutors and families. Specifically, we looked for: i) Exploring according to the perceptions of the tutors and family members (FM) how an ATD can improve the wellbeing and quality of life of diabetics (both dogs, and humans with diabetes were part of a medical association named Associação Pata d’Açúcar – Medical Dogs for Diabeties (from now onwards Pata d’Açúcar) on which dogs are trained to be ATD to latter be attributed to patients with diabetics and ii) To understand how ATD may occupy different roles throughout the time: from ATD to companion animals (CA) or even family members (FM). Our methodological approach was a qualitative one, centred in observation and semi-structures interviews applied to patients from Pata d’Açúcar. All Humans that accepted to be part for this study were interviewed and observed in different phases of shared coexistence with ATD’s: those who lived with an ATD for more than 5 years, more than 2 years and finally, just for a few months. Our sample was probabilistic and stratified. The main conclusion of our study is that for most of the interviewees, ATD’s started to being CA and simultaneously FM. Furthermore, ATD’s did also work as true ice-breakers in the case of children with difficulties in socializing with peers, facilitating the interactions between individuals of the same or similar age groups.

Published: June 2024

O presente artigo tem por objetivo apresentar a face interlocutiva dos documentos escolares individuais no âmbito da Socioterminologia (Gaudin, 1993), da interlocução (Ducrot, 1987), da Teoria Comunicativa da Terminologia (Cabré, 1999), do Discurso (Maingueneau, 2001). Formamos as instâncias hierárquicas no sistema educacional brasileiro em relação ao espaço temporal entre as LDB 5.692/1971, LDB 9.394/1996 e a legislação complementar. As análises pautam-se na Abordagem Terminológico-Discursiva (ATD) por meio da qual termos são discursos mandatários, reproduzidos em ambientes de situações de trabalho, em textos injuntivos, cujos gêneros textuais no domínio pesquisado, assemelham-se ao controle de ações, providências, modos de elaboração e execução e de interlocutores de uma comunidade de especialistas em seus postos de trabalho. Por meio dessa pesquisa, reconhecemos as principais características que subjazem à formação dessa terminologia, à interlocução textual e aos aspectos morfossintáticos e léxico-semânticos. Concluímos que essas interlocuções acontecem nos diferentes níveis da hierarquia institucional; por meio de textos escritos; são reproduzidas em diferentes instâncias dos documentos legais e por diferentes interlocutores. Os termos se concretizam via gêneros textuais num contexto sócio histórico situado; são reproduzidos como registro social e político, no qual os locutores se fazem presentes na interlocução textual de maneira não presencial, ou seja, sem que haja interações face a face o termo é resultado de uma construção entre locutor e interlocutores. E, por fim, há também a formação de rede semântica em torno de um termo base acrescentando novas denotações.

Macrophytes are aquatic plants that can cause environmental and economic damage due to their rapid growth in eutrophicated environments; however, this characteristic makes these biomasses promising alternatives for biodiesel production. Thus, this study aims to characterize and evaluate the chemical composition of the biodiesel produced from the macrophyte Salvinia molesta DC Mitchell (Salviniaceae). The biodiesel production was carried out in situ through the ethyl and methyl process. Attenuated total reflectance-Fourier transform infrared spectroscopy (FTIR-ATR) and gas chromatography with a flame ionization detector (GC-FID) were used to characterize the product. A commercial sample was also analyzed for comparison purposes. The biofuel produced with ethanol and methanol showed characteristic peaks between 900 to 1300 cm-1 and 1750 to 1735 cm-1 in the FTIR-ATR. Both samples showed less unsaturation degree compared to the commercial sample, with 34.44% of monounsaturated compounds (MUFA) and 36.73% of polyunsaturated compounds (PUFA) for methylic biodiesel, 34.79% of MUFA and 36.89% of PUFA for ethylic biodiesel, and 55.34% of MUFA and 24.14% of PUFA for commercial biodiesel. Samples produced by both routes showed similar chemical composition, with higher contents of saturated compounds than the commercial sample. The average chain size and the number of double bonds are smaller for S. molesta samples, 17.38 and 1.15 for S. molesta biodiesels and 17.65 and 1.41 for commercial biodiesel, respectively. The chemical composition of S. molesta biodiesel demonstrates the potential to be an alternative to commercial biodiesel.

Published: June 2024

Temporins are small antimicrobial peptides which have cytotoxic effects against different cancerous cell lines. However, their cytotoxicity against normal cells has been reported in some studies. Designing new temporin analogs with selective cytotoxicity against cancerous cell lines is considered a goal in drug development. In this regard, four new temporin-1CEa analogs (either C-terminally α-amidated or not) with increased net positive charge, as well as the potential of hydrogen bond formation were designed and their selective cytotoxicity against prostate carcinoma cell line (LNCaP) was evaluated. MTT assay was employed to test the simultaneous effects of the modifications on the cytotoxicity of the analogs against both normal (HFFF2) and cancerous (LNCaP) cell lines. Then, the in vitro selectivity index of each analog was determined using the equation of selectivity index (SI= IC50 of peptide against normal cell line / IC50 of peptide against cancerous cell line). The structural modifications of temporin-1CEa (increasing the net positive charge and removing C-terminally amidated group, as well as the potential of hydrogen bond formation on the non-polar face of α-helical structure) reduced the cytotoxicity of K2K3W15-COOH analog against both cancerous (LNCaP) and normal (HFFF2) cell lines. However, the modifications resulted in improving the in vitro selectivity index of K2K3W15-COOH compared to the temporin-1CEa (1.67 vs. 1.33, respectively). The results of the present study indicated that some structural modifications may lead to a diminution in the cytotoxicity of new analogs against cancerous cells. However, the same modifications can be associated with better selectivity indexes of new analogs due to a further decrease in their cytotoxicity against normal cells.

A 20-year single private sector tertiary care center experience
Authors: Abeysuriya Vasitha , Chandrasena Lal
Published: June 2024

Background and objective: The presence of a breast lump is an alarming experience. This is because of the growing awareness of breast cancer among the public. Therefore, a comprehensive diagnosis of breast lumps is vital. This study aims to identify the clinical and histological characteristics of breast lumps of patients presenting to a tertiary care center in Colombo, Sri Lanka. 
Methods: This 20 year, retrospective study analyzed the clinical and histological characteristics of all patients with breast lumps who were admitted only to Nawaloka Hospital, Colombo from 2003 to 2023. Data were retrieved through past medical records and a computer-based health information system from Nawaloka Hospital.  A general surgeon analyzed all the records. The records were analyzed with relation to demographics, presenting symptoms, presence of a lump or mass, and histological diagnosis. This study was aimed to determine the characteristics of breast lumps in a selected sample of patients who were admitted with breast lumps to a single private sector tertiary care hospital. Ethical clearance was granted. No conflict of interest.
Results: Total of 352 patients had breast lumps [female-342 (97.1%): male-10(2.9%)]. Data from 342 female and 10 male patients who were admitted with breast lumps or masses were analyzed. There were 252 /352 self-referrals, 60 / 352 referrals were from general practitioners and 40 / 352 were referred following screening. Most females were 21 to 50 years (n=219, 64%). Ninety-seven per cent of the female patients had palpable breast lumps. Most males with breast lumps were in the age group of 51-60 years. Males had relatively larger lumps (> 2cm, 80%) at the time of their presentation. In both genders, the most common quadrant for occurrence of breast lumps was the upper outer quadrant (F: 55% & M: 60%). Fibroadenoma was the commonest variety of lump in both sexes (F: 49% & M: 60%). However, most males who presented with breast lumps were found to have breast cancer (M: 40% vs. F: 10%). Histologically, invasive carcinoma of no specific type (NST) was the most common type (M: 75% & F: 63%). Thirty-five female patients had carcinoma, ten were below the age of 50 years, and two were in their early 30s.
Conclusion: Our study sample showed that most of the patients were females. The most common benign breast lump was fibroadenoma and the malignant variant was invasive carcinoma of no specific type (NST). Furthermore, it showed that at the time of presentations males had larger breast lumps with and raised percentage of malignant breast lumps.

Authors: Karmarkar Sanika U. , Badakar Chandrashekhar , Hugar Shivayogi M. , Bhusari Bhuvanesh N. , Kadam Krishna S. , Kohli Neha
Published: June 2024

Background: Children are anxious about dental procedures and the anaesthetic needle’s sight and feeling have been identified as the most fear-eliciting stimuli. Psychologists have used ‘play therapy’ to modify child behaviour to alleviate pain and anxiety during elective surgery in children. The pinwheel and bubble blower have been used in play therapy for children to bring about deep breathing which in turn brings about relaxation and anxiety reduction. Objectives: To evaluate and compare the use of two relaxation breathing exercises for anxiety reduction before and after administration of local anaesthesia for 6–12-year-old children undergoing dental treatment. Method: Forty-five children were divided into 3 groups as control, pinwheel breathing exercise and bubble blowing breathing exercise. The children were given a demonstration of the breathing exercise before local anaesthesia administration and asked to perform the exercise for 3 to 5 minutes. Anxiety was measured before and after administration of local anaesthesia with pulse rate and Venham’s picture scale score.  Results: Post-operative rise in pulse rate was seen in all groups but was statistically significant in the control group and the bubble blowing breathing exercise group (p<0.05). The least rise was seen in the pinwheel breathing exercise group. The post-injection Venham’s picture test score was the same as the pre-injection score in the pinwheel exercise group but had increased for the other two groups which was statistically not significant. Conclusions: The play therapy relaxation breathing exercises can be successfully used for anxiety reduction in children receiving local anaesthesia.
Knowledge and awareness of paediatric basic life support among parents in the Lady Ridgeway Hospital for Children, Colombo, Sri Lanka
Authors: Madura Arachchige Hasitha Madusanka Dilruk
Published: June 2024

Background: Out-of-hospital cardiac arrest in children is uncommon but significant, with poor survival rates and high morbidity. Choking in children is common but less reported with high mortality.  Early commencement of cardiopulmonary resuscitation (CPR) in cardiac arrest or following of choking algorithm in a case of choking is important for survival of the victim.  Objectives: To survey the knowledge, awareness and attitudes of parents in Sri Lanka regarding paediatric Basic Life Support (BLS) including early treatment of choking.Method: This was a descriptive cross-sectional study and questionnaires were administered to parents of children managed at the Preliminary Care Unit (PCU) and wards 2 and 4 of Lady Ridgeway Hospital, Colombo from October 2022 to January 2023. Sample size was calculated according to the Lwanga and Lemeshow method. Total respondents were 350 out of total participants of 415. The questionnaire consisted of four sections for assessment of demography, knowledge and attitude. Total scores of each aspect were analysed with respect to different factors.Results: Of the participants, 95% did not have BLS training and the largest proportion of them was educated only up to the General Certificate of Education (GCE) ordinary level. Knowledge of specific aspects of BLS or choking was demonstrated by only about 10% of the population. Nearly 50% of parents had identified substandard common practices as correct methods. There was no statistically significant correlation between total score of each aspect and previous observations, training or highest educational level. It was assessed with 95% confidence interval. However, seeing BLS had improved knowledge of basic health (p=0.013).  Conclusions: Seeing the procedure on television or other resources had not improved knowledge of BLS. Workshops were the preferred method to improve their knowledge on BLS including the choking algorithm and participants’ educational level was not important in organizing such an event.

Published: June 2024

Poor sleep quality among nurses is a major concern for the healthcare system. It might impair the nurses’ capacity to carry out their duties, endangering the patients’ health and safety. The objectives of this study were to identify the levels of sleep quality, mental well-being, and work performance, and the relationship between these variables and work performance. A cross-sectional study was conducted among 143 nurses from teaching hospitals. A self-administered questionnaire consisting of the Pittsburgh Sleep Quality Index, the Warwick-Edinburgh Mental Well-being Scale, and the Individual Work Performance Questionnaire was used to measure sleep quality, mental well-being, and work performance, respectively. The findings indicated that 77.6% of nurses had poor sleep quality, and 90.2% had poor mental well-being. A p-value of 0.05 indicated a relationship between sleep and contextual performance, whereas p>0.05 indicated no relationship between mental health and sleep quality. Age and educational attainment were related to work performance, but only gender was associated with mental health (p=0.05). In conclusion, the study outcomes emphasized the critical importance of addressing poor sleep quality and mental well-being among nurses to optimize their contextual performance. The relationship between demographic factors and professional outcomes further underscored the complexity of factors influencing the well-being and performance of nurses, requiring tailored interventions for comprehensive improvement within this area.
Influence of water quality and seasonal variations on freshwater macroinvertebrate diversity and community structure in wastewater treatment ponds, Phetchaburi Province, Thailand
Authors: Thongdang Wasinee , Chaichana Ratcha
Published: June 2024

Wastewater originating from the Phetchaburi municipality undergoes treatment in a series of five distinct stages at the King’s Royally Initiated Leam Phak Bia Environmental Research and Development Project (LERD) in Phetchaburi province, Thailand. These stages involve a sedimentation (pond 1), three oxidation ponds (ponds 2 to 4), and a final stabilization pond (pond 5). These ponds serve as habitats for macroinvertebrates; consequently, their diversity and composition might be influenced by fluctuations in water quality and seasonal variations. The primary aim of this research was to analyze the diversity and species composition of macroinvertebrate communities concerning varying levels of organic contamination across the five wastewater treatment ponds at LERD. This investigation spanned three seasons: cold season (December 2019), rainy season (July 2020), and hot season (April 2021). The findings revealed that the diversity and species composition of macroinvertebrate communities displayed distinct alterations across multiple environmental gradients, especially identifying the significant influence of organic loading levels observed in ponds 1 to 5. The macroinvertebrate communities exhibited two distinct groupings, with the Chironomidae and Candonidae or ostracods prevailing prominently in ponds 1 and 2 (heterogenous environments). This prevalence was attributed to the high levels of detrital food and the robust resilience of chironomid larvae and ostracods to organic pollution, thriving even in environments characterized by low dissolved oxygen levels. Conversely, the prevalence of snails from the Thiaridae family in ponds 3 to 5 (homogenous environments) indicated improved water quality conditions, notably lower organic matter levels, and a higher dissolved oxygen content. In addition, the study identified seasonal variations in macroinvertebrates, likely influenced by the differing organic loading and environmental conditions. Thus, this research provided insights into the factors shaping macroinvertebrate communities in a wastewater treatment system.
Factors Influencing Athletic Training Services in California Secondary Schools: A 5-Year Update
Authors: Eason Christianne M. , Goble Sarah E. , Post Eric G. , Huggins Robert A. , Casa Douglas J. , Stearns Rebecca L.
Published: June 2024

Context

California is the only state that does not regulate the athletic training profession, allowing unqualified personnel to be hired and call themselves athletic trainers (ATs). The benefits of employing a certified AT in the secondary school setting are numerous, but efforts to push regulation legislation continue to fail in California.

Objective

To describe the availability of certified ATs in California secondary schools and explore factors influencing AT employment.

Design

Cross-sectional study.

Setting

Online survey.

Patients or Other Participants

Participants from 1538 California secondary schools.

Main Outcome Measure(s)

Officials from member schools completed the 2022–2023 California Interscholastic Federation Participation Census. Participants provided information specific to enrollment, sport participation, access to automated external defibrillators, and whether the school had ATs on staff. The AT’s certification status was independently verified. Enrollment data specific to ethnicity, race, and percentage of students eligible for free meals were obtained through the California Department of Education Statistics.

Results

More than half (51.6%) of California secondary schools did not employ a certified AT, and 8.3% employed unqualified personnel as ATs. Nearly half (43%) of student-athlete participants were enrolled at schools with no certified AT. Schools that employed certified ATs had a lower proportion of students eligible to receive free and reduced-price meals. The average percentage of Hispanic or Latino students was greater in schools with no certified AT and schools that employed unqualified personnel as ATs than schools that employed certified ATs.

Conclusions

Data indicate that, in a 5-year period, access to athletic training services in California secondary schools has not improved. Large gaps in access to athletic training services and clear socioeconomic and racial and ethnic disparities exist. Efforts to educate stakeholders on the importance of athletic training regulation in California should continue.

Published: June 2024

Athletic trainers are increasingly used in nontraditional settings, such as in law enforcement, where they can contribute to healthcare management, including concussion management of law enforcement officers (LEOs). Despite the prevalence of concussions among LEOs, there is a notable gap in concussion management guidelines for this population. LEOs may lack the education and resources necessary for concussion recognition and proper management. Drawing on advancements in concussion management in athletes and military personnel, here, we present a comprehensive framework for concussion management in LEOs encompassing concussion education, a graduated return-to-duty protocol, and considerations for implementation and documentation specific to law enforcement. We also present several barriers and facilitators to implementation. Due to job requirements, it is critical for law enforcement organizations and their medical providers to adopt a concussion management strategy. Without proper concussion management, LEOs may risk subsequent injury and/or suffer from prolonged recovery and adverse long-term outcomes.
Managing Opioid Addiction in Adolescents in the Community: Experiences from Two Cases
Authors: Brar Manmeet Kaur , Chatterjee Biswadip , Sarkar Siddharth , Prakash Brahm
Published: June 2024

Introduction:

Adolescent opioid use in India has emerged as a critical public health concern, with a 2018 survey revealing 1.8% of adolescents aged 10–17 years as past-year opioid users. We present here the experiences of two cases of adolescent opioid users from a community-based drug treatment clinic in Delhi.

Case Description:

Case 1 involved a 17-year-old male suffering from opioid and tobacco dependence. His treatment, starting about 3 years back, showcased challenges in withdrawal management, leading to successful opioid agonist treatment (OAT), employment, and positive social reintegration over follow-up. Case 2 was a 15-year-old male with opioid, cannabis, tobacco, and volatile solvent dependence who presented about 2.5 years back to us. Despite treatment initiation in February 2021 and positive strides in OAT, employment, and cessation of injecting drug use, challenges persisted, highlighting the necessity for effective tailored interventions in managing substance use disorder in adolescents.

Conclusion:

Adolescent opioid use disorder can be managed in the community with OAT, though challenges of dropout do remain.

Published: June 2024

Background:

Sports-related injuries pose a significant health and economic challenge globally, with the Kingdom of Saudi Arabia (KSA) being no exception. The role of nutrition knowledge (NK) in both sports performance and injury management is paramount.

Aims and Objectives:

This study aimed to assess the levels of nutritional knowledge and explore the factors influencing it among injured athletes in the KSA, in order to determine the relationship between nutritional knowledge and the probability of injury recurrence.

Materials and Methods:

This cross-sectional study was conducted in five regions (North, Central, South, East, and West) of the KSA between December 2023 and March 2024. An online survey was utilized to collect data, with invitations to participate being distributed to rehabilitation centers and hospitals across various regions of Saudi Arabia.

Results:

The survey assessed NK levels and explored determinants of NK among injured athletes in Saudi Arabia. A total of 125 participants, comprising 96 men and 29 women, completed a self-reported structured questionnaire. The findings revealed that a considerable proportion of injured athletes exhibited a poor understanding of NK, with 68.8% achieving scores within the poor knowledge range. Furthermore, the study identified significant disparities in knowledge levels based on educational level (P = 0.001). In addition, a strong correlation was reported between good NK and a reduced likelihood of recurring injuries (P = 0.039).

Conclusion:

These results highlight the need for targeted nutrition education to enhance injured athletes’ rehabilitation and well-being. Addressing the poor knowledge of nutrition is therefore crucial in optimizing the recovery and performance outcomes of injured athletes in Saudi Arabia.
Effect of iron supplementation on physical and physiological variables of active females
Authors: Roy Gopa Saha , Mondal Priyatosh
Published: June 2024

Introduction:

This study investigates the impact of iron supplementation on physiological and physical variables among active female students. Iron is essential for oxygen transport and is routinely depleted among iron runners due to exercise intensity. Considering the complicated relationship between exercise intensity, participants’ current health status, eating habits, and normal iron levels, this study seeks to illuminate whether iron supplementation benefits female athletes recruited among students from Burdwan University’s M.P.Ed. Department.

Materials and Methods:

This study targets a population of 10 female students aged between 22 and 27 years. Participants were selected on the basis of the homogeneity of their age, height, and weight. The study design was conducted as pretest/posttest research. Participants were provided with iron supplements, Punarnaba Moondur, with 250 mg of iron to be taken twice a day with honey and fed as specified. Hemoglobin level and various physiological and physical test parameters were chosen as primary outcomes. Using a t-test setting, P = 0.05, the difference between pre- and postparameters was analyzed.

Results:

Analysis indicates significant positive variations in postintervention hemoglobin level results in relation to preintervention results. Thus, the iron level was successfully increased. Comparably, various physiological functions and physical fitness parameters were improved among the participants: Their muscles worked more efficiently, and physical capabilities were generally enhanced.

Conclusion:

The use of Punarnaba Moondur as an iron supplement significantly increased the amount of hemoglobin among the active students. This development led to improved physiological and physical capacity. Parametric supplementation can be used to correct exercise-induced iron deficiency in female athletes to increase exercise performance and health outcomes. This study highlights the value of attenuation nutrition as an intervention tool against exercise-induced iron depletion.
Auto-Ignited Combustion Control in an Engine Equipped with Multiple Boosting Devices
Authors: Kang Jun-Mo
Published: June 2024

The combustion timing of auto-ignited combustion is determined by composition, temperature, and pressure of cylinder charge. Thus, for a successful auto-ignition, those key variables must be controlled within tight target ranges, which is challenging due to (i) nature of coupling between those variables, and (ii) complexity of managing multiple actuators in the engine. In this article, a control strategy that manages multiple actuators of a boosted homogeneous charge compression ignition (HCCI) engine is developed to maintain robust auto-ignited combustion. The HCCI engine being considered is equipped with multiple boosting devices including a supercharger and a turbocharger in addition to conventional actuators and sensors. Since each boosting device has its own pros and cons, harmonizing those boosting devices is crucial for successful transient operation. To address the multi-variable transient control problem, speed-gradient control methodology is applied to minimize coupling between boosting devices. Simulation results show that the control strategy overcomes turbo lag by utilizing the supercharger during transient. The controller developed is still appliable to manage multiple boosting devices with conventional engines as well as HCCI engine.

Published: June 2024

The purpose of this work is to present the process of the destruction of cultural property of the Muslim community during the warfare conducted on the territory of Bosnia and Herzegovina (BiH) in 1992–1995. The work is based on historical and press sources in Serbian, Bosnian and Croatian. Field research conducted in 2000 and 2022 to obtain information on the number of demolished and restored mosques in BiH also makes an important contribution. In addition, in-depth interviews were conducted with Slovak soldiers who served in NATO IFOR operations, as well as with representatives of international institutions. Research results indicate that during the war in BiH (1992–1995) the Muslim community suffered the greatest losses of cultural property. 614 mosques were destroyed. Serbian armed troops carried out most of the damage, while Croatian armed troops did less. After the war, no individual was held responsible for the destruction of cultural property. The case of BiH shows that international law still does not protect religious sites.
Mutações no Gene IBA57 como Causa de Leucodistrofia na Idade Pediátrica: Um Caso Clínico
Authors: Ladeira Rodrigues Leonor , Janeiro Patrícia , Proença dos Santos Tiago , Coelho Joana
Published: June 2024

A produção de ATP no corpo humano é dependente da fosforilação oxidativa que, por sua vez, é regulada pelo DNA mitocondrial e nuclear.
Mutações nos genes envolvidos na cadeia mitocondrial de transporte de eletrões e no processo da fosforilação oxidativa foram recentemente descritos como causa de leucodistrofias. Estas são doenças genéticas que afetam primariamente a substância branca cerebral.
Um dos genes envolvido nesta doença é o gene IBA57 (1q42.13) que é responsável por codificar uma proteína localizada na mitocôndria e que faz parte do cluster Fe/S. A proteína em questão chama-se putative transferase CAF17 e está envolvida na ma- turação das proteínas mitocondriais 4Fe-4S.
Reportamos o caso de uma criança com uma doença neurodegenerativa e um pa- drão imagiológico indicativo de leucodistrofia. Após a análise genética, foram identi- ficadas duas variantes em heterozigotia no gene IBA57.

Authors: Oliveira Raquel , Batista Raquel , Flores Priscila , Massano Ana , Galo Sérgio , Martins Isabel
Published: June 2024

Cerebral amyloid angiopathy-related inflammation (CAA-ri) is a rare subtype of CAA characterized by a perivascular inflammatory response to amyloid deposition in the brain.
The authors detail the case of a 74-year-old man with aphasia, who was diagnosed with probable CAA-ri following brain magnetic resonance imaging. Treatment recom- mendations included a 5-day course of high-dose methylprednisolone.
CAA-ri may manifest with transient or permanent neurological symptoms resem- bling a transient ischemic attack or stroke, potentially leading to misdiagnosis and inadequate long-term treatment. Hence, our objective is to highlight the clinical and imaging findings of this case.

Authors: Nóbrega Caldeira Fiona , Freitas Kaylene , Forno Andreia , Cardoso Cátia
Published: June 2024

First described in 2018, heterozygous variants of the RHOBTB2 gene, affect the translation of a Rho GTPase protein, essential in neuronal development and synaptic plasticity. The few cases described are characterized by a clinical spectrum of epileptic encephalopathy, psychomotor and cognitive delay, microcephaly, nonspecific facial dysmorphism and movement disorder.
We report a case of a female child, who had two seizures at 28 days of age. She exhibited a normal psychomotor development, until she had another seizure at 6 months, after which she started showing a movement disorder, followed by impair- ment of psychomotor development. Amongst the multiple hospitalizations, one of them was due to status epilepticus with severe rhabdomyolysis. At the age of 7, by ex- ome sequencing, a de novo pathogenic variant was identified in the RHOBTB2 gene.
Although the main characteristics of this syndrome have been described in previous studies, its possible relation with rhabdomyolysis has never been reported.

Flood risk assessments influence urban and land use planning, which presents a significant research problem. Although quantitative risk and hazard modelling techniques exist, trustworthy, logical vulnerability assessment methodologies still need improvement. This is especially valid when evaluating buildings' susceptibility to flooding. This vulnerability is typically conceptualized using empirical data and is significant for communities' and individuals' safety and economic reasons. However, these empirical methods are fraught with considerable uncertainties, primarily due to the inadequate representation of the damage-causing mechanisms on the building envelope. This research aims to further this field by examining the structural vulnerability of traditional brick buildings in flash-flooded alpine settings. A conceptual model with a reduced physical basis that only needs a small amount of input data is suggested using a limit analysis framework; the resistance of a wall affected by a flash flood is examined while taking various geometric ratios and building layouts into account. The stability thresholds stated in the results of numerical finite element models of the studied geometries were positively compared with the dimensionless form as a function of the water depth. When the suggested vulnerability model is used in risk mitigation measures, accurate data appropriate for a preliminary risk assessment of extensive building stocks is produced.

Published: June 2024

This study examined the influence of service infrastructure on curriculum implementation in public universities in Northern Uganda. Service infrastructure was studied in terms of electricity, water, toilets, and healthcare facilities, while curriculum implementation was considered in terms of preparation for teaching, content delivery, and assessment of learning. It was hypothesised that service infrastructure has no significant influence on curriculum implementation in public universities in Northern Uganda. The study embraced a convergent parallel mixed-methods research design. Quantitative data was obtained from 123 respondents through questionnaires. Qualitative data was collected from 26 participants through interviews, 61 participants through FGDs, and observations. The study revealed that generally, the level of curriculum implementation was low at a mean of 2.58 (51.6%), the level of services infrastructure was moderate at a mean of 3.43 (68.6%), and the coefficient of determination (R2) was at .214, implying that services infrastructure explained 21.4% of the variations in curriculum implementation in public universities in Northern Uganda. The null hypothesis that service infrastructure has no significant influence on curriculum implementation in public universities in Northern Uganda was rejected because the P-value of 0.000 was found to be less than the level of significance of 0.05. It was concluded that service infrastructure is a vital requirement for effective curriculum implementation in public universities in Northern Uganda. Therefore, it was recommended that the public universities further improve the state of their service infrastructure, like electricity, water, toilets, and health care facilities, to improve curriculum implementation, especially in areas of preparation for teaching, content delivery, and assessment of learning. Additional studies should be carried out on other factors contributing to 78.6% of the influence of curriculum implementation in public universities in Northern Uganda.

EXPLORING GRADE 7 STUDENTS’ SECOND LANGUAGE DIFFICULTIES: IMPLICATIONS FOR TEACHING AND LEARNING
Authors: Gruta Realyn A. , Astillero Susan F.
Published: June 2024

This study investigated the second language difficulties of Grade 7 students in one national high school in Sorsogon province, Philippines, S.Y. 2023-2024. Specifically, it identified the grammatical errors of students in their narrative essays along with subject-verb agreement and verb tenses. It determined the second language difficulties leading to their grammatical errors and their implications for language teaching and learning. Based on the 45 essays analyzed by the 15 students, the results showed that the grammatical errors identified were along the verb tense, which ranked highest (66%), and subject-verb agreement (42%), indicating a high level of students’ writing difficulty. Several linguistic difficulties that contributed to these errors were vocabulary gaps, limited knowledge of grammatical rules, syntactic differences between the students’ local language (L1) and English language (L2), the challenging learning environment, lack of resources, distractions, and insufficient family support. The students’ L2 difficulties may have implications for teaching and learning, particularly in terms of communicative effectiveness, reading comprehension, shift in teaching approach, and balancing formal and communicative activities.

UNVEILING THE ESSENCE OF UNIVERSITY EDUCATION: A CRITICAL ANALYSIS OF KARL JASPERS’ EXISTENTIAL APPROACH
Authors: Tran Thi Thao
Published: June 2024

This paper critically assesses Karl Jaspers’ existential viewpoint concerning the fundamental nature of university education. In a contemporary context where the pursuit of credentials prevails, Jaspers challenges traditional paradigms by underscoring the university’s distinctive role beyond the mere acquisition of job-related skills. The abstract delves into Jaspers’ critique of an education system fixated on efficiency, advocating for the cultivation of intellectual life and existential awareness. Through a thorough analysis, the article reexamines the objective of university education, transcending the narrow focus on credentials to embrace a comprehensive vision that aligns with Jaspers’ philosophical principles. Practical insights for applying Jaspers’ philosophy in contemporary educational settings are presented, facilitating a transition towards a more purposeful and contemplative academic experience. The research methodology employed encompasses narrative analysis and philosophical inquiry.

Authors: Souza Carlos Antonio Nascimento de
Published: June 2024

O presente artigo discute a emoção no universo das escolas de samba do Rio de Janeiro. Tomada como um elemento central e um sentimento universal durante o processo de construção do desfile de carnaval, a emoção é capaz de impulsionar as escolas de samba na disputa do concurso de carnaval. Diante da mobilização frequente de múltiplos sentimentos pelos diversos atores das agremiações, este artigo se propõe a investigar os impactos, efeitos e consequências da emoção no carnaval das escolas de samba. Para tanto, tem-se como objeto central do estudo o desfile Um defeito de cor, baseado em livro homônimo (Gonçalves, 2006), da escola de samba Portela, eleito nas categorias melhor enredo e melhor desfile do carnaval 2024 em uma premiação de grande relevância no carnaval do Rio de Janeiro. A análise do trabalho está centralizada no campo da antropologia das emoções e em conceitos desenvolvidos por Lila Abu-Lughod e Catherine Lutz (1990). Para além de apresentar a sistematização desse campo teórico pelas autoras na década de 1980, o artigo expõe elementos presentes no universo das escolas de samba e o desfile de 2024 da Portela. Como resultado, observou-se que a emoção é o fator responsável por produzir uma dimensão micropolítica no carnaval das escolas de samba do Rio de Janeiro que busca alterações da realidade social dos desfilantes e do público.

Published: June 2024

As the third greatest cause of death globally, cancer is a malignant disease. Adolescents aged 11 to 24 are more likely to get breast cancer, and their survival rates are generally poorer. One of the things that contributes to the high prevalence of breast cancer because of ignorance is lack of awareness. Thus, steps must be taken to remedy this problem, one of which is introducing the word square model into the classroom. The purpose of the study is to examine how word square model teaching affects adolescent girls' awareness of breast cancer in the classroom. A Pre-Experiment using the One Group Pretest Posttest Design technique was the study methodology employed. There were 136 female students in seventh grade at SMPN 03 Jember who made up the study's population. With a sample size of 56 respondents, proportionate random sampling was used to choose the participants. The Wilcoxon test was employed in data analysis to assess the impact of word square model education on the degree of breast cancer knowledge. The study's findings demonstrated that word square model instruction had an impact on teenage girls' knowledge levels in the classroom, with the majority of them falling into the "good" category with p < 0.05. In conclusion, this study shows that teaching teenage girls about the word square model has an effect on their degree of breast cancer knowledge.
