BACKGROUND

The COVID-19 pandemic disrupted education worldwide, prompting a rapid shift to emergency remote teaching that challenged students’ learning and mental health. Nursing students, in particular, faced heightened pressures due to the suspension or online adaptation of essential clinical experiences, alongside the need to master theoretical and practical competencies. Emerging evidence indicates that such stressors adversely affect students’ emotional and psychological well-being, potentially influencing academic outcomes. Understanding the relationship between mental health and academic performance among nursing students is crucial for developing targeted interventions that support their well-being and professional readiness.

OBJECTIVE

This study analyzed the mental health status and academic performance of graduating nursing students during the challenging period of remote learning amid the pandemic in a government school in Leyte.

METHODS

The study utilized a descriptive correlational design to explore the relationships between mental health status and academic performance among nursing students. A modified self-administered questionnaire was utilized to gather data. Ethical approval from Eastern Visayas Health Research and Development ConsortiumEthics Review with ERC number 2023-024 was secured, and data collection occurred through various methods. Data analysis used SPSS version 24, emphasizing the importance of understanding these relationships in educational settings.

RESULTS

The study assessed the demographic profile, online learning attributes, mental health status, and academic performance of 20 nursing students during the pandemic. All students passed their courses, despite reporting moderate emotional loneliness and irritability, but minimal fear of COVID-19. Significant correlations were found between demographic factors and mental health indicators. The null hypothesis, suggesting no relationship between demographic factors and mental health, is void, as significant associations were identified. Recommendations include enhancing mental health support in nursing education to address these challenges.

CONCLUSION

This study highlights the experiences of 20 nursing students from a government college in Leyte during the COVID-19 pandemic. Predominantly young women from rural, low-income backgrounds, these students faced challenges like poor internet access but successfully completed their academic requirements, showcasing resilience. While they reported low fear of COVID-19, moderate emotional loneliness and irritability indicated underlying mental health issues. The findings stress the need for educational institutions to provide mental health support and address the digital divide to enhance student well-being and success.

In recent years, it has become a new direction in the field of neuroscience to explore the mode characteristics, functional significance and interaction mechanism of resting spontaneous electroencephalography (EEG) and task-evoked EEG. This paper introduced the basic characteristics of spontaneous EEG and task-evoked EEG, and summarized the core role of spontaneous EEG in shaping the adaptability of the nervous system. It focused on how the spontaneous EEG interacted with the task-evoked EEG in the process of task processing, and emphasized that the spontaneous EEG could significantly affect the performance of tasks such as perception, cognition and movement by regulating neural activities and predicting external stimuli. These studies provide an important theoretical basis for in-depth understanding of the principle and mechanism of brain information processing in resting and task states, and point out the direction for further exploring the complex relationship between them in the future.

A brain-computer interface (BCI) based on motor imagery (MI) provides additional control pathways by decoding the intentions of the brain. MI ability has great intra-individual variability, and the majority of MI-BCI systems are unable to adapt to this variability, leading to poor training effects. Therefore, prediction of MI ability is needed. In this study, we propose an MI ability predictor based on multi-frequency EEG features. To validate the performance of the predictor, a video-guided paradigm and a traditional MI paradigm are designed, and the predictor is applied to both paradigms. The results demonstrate that all subjects achieved > 85% prediction precision in both applications, with a maximum of 96%. This study indicates that the predictor can accurately predict the individuals' MI ability in different states, provide the scientific basis for personalized training, and enhance the effect of MI-BCI training.

Reach-to-grasp movements require integrating information on both object location and grip type, but how these elements are planned and to what extent they interact remains unclear. We designed a new experimental paradigm in which monkeys sequentially received reach and grasp cues with delays, requiring them to retain and integrate both cues to grasp the goal object with appropriate hand gestures. Neural activity in the dorsal premotor cortex (PMd) revealed that reach and grasp were similarly represented yet not independent. Upon receiving the second cue, the PMd continued encoding the first, but over half of the neurons displayed incongruent modulations: enhanced, attenuated, or even reversed. Population-level analysis showed significant changes in encoding structure, forming distinct neural patterns. Leveraging canonical correlation analysis, we identified a shared subspace preserving the initial cue's encoding, contributed by both congruent and incongruent neurons. Together, these findings reveal a novel perspective on the interactive planning of reach and grasp within the PMd, providing insights into potential applications for brain-machine interfaces.

Introduction: This paper explores the impact of a remediation programme on medical students’ overall performance. It also suggests a potential remediation framework encompassing planned learning sessions by subject experts, individualised coaching from an alumni group, professional counselling for psychological support, and participants’ learning commitment. Methods: Twenty-seven students were identified as academically weak students (AWS). This was done based on two criteria: students who failed more than one mini test (out of six mini tests) during the delivery of the first-year curriculum, and students who had to repeat the study after failing the end-of-year-1 (EOY-1) exam. A remediation strategy consisting of 1) planned learning sessions, 2) individualised alumni coaching sessions, and 3) counselling sessions were offered to these students. However, participation is optional (Group A (n=12) – participants and Group B (n=15) – non-participants). Evaluation of the remediation programme is performed using mixed-method analysis: 1) comparative analysis of the performance of Group A vs Group B, and 2) qualitative analysis using a semi-structured interview with openended questions to obtain students’ perceptions of the programme. Results: Group A showed significantly higher pass rates (83% vs. 66%, p < .001) in the EOY-1 exam. Interviews revealed positive perceptions of personalised alumni coaching and its role in enhancing learning and confidence. Conclusion The study concludes that early identification and targeted remediation support improve academic outcomes, benefit the student’s educational journey, and contribute to quality education.

Objective: This study aimed to determine and quantify the presence of the active components in Thai propolis extracts using high performance liquid chromatography (HPLC). Moreover, the anti-caries potential of Thai propolis extract and its active ingredients were tested. Methods: Fifty milligrams of Thai propolis were extracted using either 100%, 90%, 80%, or 70% ethanol and subsequently analyzed using HPLC with a mobile phase gradient system of 10-100% acetonitrile in 0.05% aqueous ortho-phosphoric acid, flow rate of 0.8 mL/min, and detection wavelength of 280 nm. Varying concentrations of Thai propolis extracts as well as four active ingredients were subjected to agar well diffusion test against the growth of Streptococcus mutans (S. mutans) or Lactobacillus caseii (L. caseii). Results: The concentrations of the four active ingredients: vicenin-2, vitexin, apigenin, and cinnamic acid, were significantly affected by ethanolic concentrations. The chromatographic peaks of all active ingredients from 70% and 80% ethanolic extracts appeared more defined, as compared to those which used higher concentrations of ethanol for extraction. Except for the absolute ethanolic extract, all of the examined propolis extracts, as well as its active ingredients inhibited both S. mutans and L. caseii. Conclusions Thai propolis extracts contain vicenin-2, vitexin, apigenin, and cinnamic acid as part of its active ingredients. These were found to be significantly affected by the increase in ethanol during its extraction. The presence of these active ingredients might have contributed to the anti-caries potential of Thai propolis extracts.

BACKGROUND

Nursing, as a profession, is a facet where job satisfaction and performance matter. In the changing landscape of nursing practice in the Philippines and the aftermath of the COVID-19 pandemic, it is imperative to revisit and to perform an empirical investigation of the current state of nurses' job satisfaction and performance in the hospital setting. This study aimed to describe the job satisfaction and performance among staff nurses in private and government hospitals in Baguio City.

DESIGN

Using a quantitative descriptive cross-sectional survey design, a sample of 313 randomly selected staff nurses working in two private and two government hospitals in Baguio City were surveyed from March to April 2023, using a questionnaire. This study's protocol was approved by two ethics committees, namely the Saint Louis University Research Ethics Committee and the BGHMC REC. Nominal data was analyzed using the SPSS trial version employing frequencies, percentages, and the Chi-square test.

FINDINGS

There are more staff nurses in both private and government hospitals who reported satisfactory job satisfaction levels (276 nurses, 87.9%) and had good job performance (303 nurses, 96.5%) in all domains. However, results show that there are more nurses (209 nurses, 90.7% ) in government hospitals who are satisfied with their jobs than in private hospital nurses (67 nurses, 80.1%) in the domains Intra practice Partnership/Collegiality (p=0.010); Challenge/Autonomy (p=0.001); Professional, Social and Community Interaction (p=0.010); Professional Growth (p=0.036); Time (p=0.009); and Benefits (p=0.045). In terms of job performance, more government nurses at 97.3% (224 nurses) rated a higher self-appraisal of job performance. In comparison, only 94.8% (79 nurses) of private staff nurses appraised themselves as having good performance. No significant differences were found in the domains of job performance, namely leadership, teaching, planning, communications, and professional development, except in critical care. In "Critical care," which showed significance, the results suggest that more nurses in government hospitals perceive higher job performance, revealing a significant difference (p=0.011) in the "critical care" domain, indicating that a higher proportion of nurses in government hospitals demonstrate superior performance in this area.

CONCLUSION

Through this study, it was learned that nurses in both private and government hospitals generally experience high job satisfaction and performance, reflecting a fulfilled workforce and indicating commendable competency among the staff nurses. However, more nurses in government hospitals report high satisfaction and perceived performance in critical care compared to those in private hospitals. Thus, the findings of this study can contribute to and serve as a rationale for policy making regarding creating a positive work environment, proper management and leadership, creation of training and skill development for critical care, providing opportunities for professional growth, and conducting regular evaluation and feedback----- all geared towards a satisfied and productive workforce.

Objective To investigate the effects of rotation stability after anterior cruciate ligament reconstruction (ACLR) on subjective outcomes,sport performance,psychological readiness,and return to sport. Methods The patients who underwent ACLR in the Sports Hospital,National Institute of Sports Medicine,General Administration of Sport of China from January 2015 to January 2021 were followed up during the period from November 2022 to December 2023.The patients were grouped according to the results of the pivot shift test (PST) of the affected knee at the last follow-up visit.A total of 66 patients who participated in the follow-up and met the inclusion and exclusion criteria were finally enrolled in this study,including 32 patients showing a negative PST result (stable group) and 34 patients showing a positive PST result (unstable group).The basic information,subjective function score,and return-to-sport performance were compared between the two groups. Results In terms of sport performance,the two groups showed differences in the limb symmetry index in single-leg hops,triple hops,and crossover hops (P=0.028,P=0.024,and P=0.044,respectively).The anterior cruciate ligament-return to sport after injury scale score was higher in the stable group than in the unstable group [(70.44±22.82) scores vs. (53.44±21.74) scores,P=0.003].The mean of KT-2000 test results in the stable group was lower than that in the unstable group [(0.53±1.02) mm vs. (2.06±2.31) mm,P=0.001].The Lysholm score,international knee documentation committee score,knee injury and osteoarthritis outcome score,Tegner score,and Marx score did not have significance between the two groups (all P>0.05).The return-to-sport rate was 43.8% (including 14.3% reaching safe return criteria,which accounted for 6.3% in all the patients) in the stable group and 35.3% (including 8.3% reaching safe return criteria,which accounted for 2.9% in all the patients) in the unstable group.There was no difference in the 60°/s isokinetic muscle strength,maximal muscle strength ratio of the affected extensor-flexor muscles,or Y-balance test result between the two groups (all P>0.05). Conclusions Knee joint rotational instability after ACLR results in poor performance in single-leg hops,triple hops,and crossover hops,low psychological readiness,and anterior-posterior knee laxity.In short- to medium-term follow-up for ACLR,the return-to-sport rate remained low regardless of knee joint rotational stability,with the majority of patients failing to meet safe return criteria.
