BACKGROUND

State universities in the Philippines should comply with the 2020 Occupational Safety and Health (OSH) standards for government workers and must be guided by the 2017 ASEAN University Network’s Healthy University Framework (HUF) for them to become healthy universities. Both policy documents identify OSH policy and programs as key components.

This study aimed to explore the challenges and opportunities in the implementation of health and safety policies and programs in a state university in the Philippines.

A case study design was used with a state university as its study site. Investigators conducted 14 key informant interviews and nine focus group discussions which were participated by system officials, campus officials, academic teaching staff, academic non-teaching Staff, support staff, and students. Thematic analysis was used to identify and understand emerging patterns and themes.

The results generated seven themes consisting of Policy and Committee, Dedicated Personnel and Unit,Budget and Technology, Collaboration, Programs and Services, Working and Learning Environment, and Role Models. The identified challenges in the implementation of health and safety programs in the university were: (1) limited budget to implement initiatives, (2) lack of collaboration among its offices, and (3) absence of a dedicated unit and staff. There were also opportunities to improve implementation: (1) strong implementation of certain policies and programs, (2) presence of a good working and learning environment, and (3) existence of role models.

The identified challenges and opportunities correspond to the elements of the system and infrastructure considered as principal determinants of a healthy university. There is a need to recognize the interrelatedness of such elements to ensure effective implementation of health and safety programs in the university. It also underscores the relevance of the HUF in promoting OSH within a university context.

INTRODUCTION

Virtual learning is the new normal brought about by the pandemic in the field of education. Consequently, students are compelled to have increased exposure to electronic screens. With digital eye strain caused by increased exposure to gadgets, this study will look for a correlation between exposure to electronic screens and the severity and frequency of headaches and migraines among students studying online.

This study aims to gain an understanding of the average exposure of students to electronic screens and if there is a high frequency of migraine due to this increased exposure so that school administrators are aware of this; and in turn, to serve as a stepping stone for future studies in the same field of research.

This study will make use of an observational comparative design also known as a cross-sectional descriptive study in order to look into the proportion of students affected by such a phenomenon at one point in time. The chosen study population will consist of medicine students currently enrolled in the University of Santo Tomas, Faculty of Medicine and Surgery. The study will make use of questionnaires in order to gather data from the sample population.

Our research study indicates a significant direct correlation as evidenced by both the Pearson correlation coefficient of 0.386 and the p-value of 0.050 between electronic screen exposure and migraine frequency/severity among UST medicine students engaged in online distance learning.

While this correlation underscores the potential health impact of prolonged screen time, the moderately low association suggests a need for cautious interpretation. Other factors explored, such as gender and year level, exhibited positive correlations of 0.283 and 2.955, respectively, but did not reach statistical significance, possibly due to the small sample size limiting the depth of analysis.

Our study highlights a significant correlation between screen time exposure and migraine severity, suggesting the need for schools adopting online or hybrid setups to consider screen hours in their policies. Given the emergence of online learning environments, these factors require careful consideration. While exploring additional factors like gender and year level, limited sample size hindered conclusive findings. Future research should focus on increasing sample size and investigating variables such as screen time quality, exposure environment and participant demographics to better understand the primary causes predisposing individuals to migraine without aura.

Background and Objective: Retinoblastoma is one of the most common intraocular cancers among children usually caused by the loss of retinoblastoma protein function. Despite being a highly heritable disease, conventional diagnostic and prognostic methods depend on clinical examination, with limited consideration of cancer genetics in the standard of care. CD133, KRT19, and MUC1 are commonly explored genes for their utility in liquid biopsies of cancer including lung adenocarcinoma. To date, there are few extensive molecular studies on retinoblastoma in Filipino patients. To this end, the study aimed to describe the copy number of CD133, KRT19, and MUC1 in retinoblastoma samples from a Filipino patient and quantitate the respective expression level of these genes. Methods: Hematoxylin & Eosin (H&E) staining was utilized to characterize the retinoblastoma tissue while fluorescence in situ hybridization (FISH) using probes specific to CD133, KRT19, and MUC1 was performed to determine the copy number of genes in retinoblastoma samples from a Filipino patient (n = 1). The gene expression of CD133, MUC1, and KRT19 was quantitated using RT-qPCR. Results: The H&E staining in the retinoblastoma tissue shows poorly differentiated cells with prominent basophilic nuclei. CD133 was approximately 1.5-fold overexpressed in the retinoblastoma tissue with respect to the normal tissue, while MUC1 and KRT19 are only slightly expressed. Multiple intense signals of each probe were localized in the same nuclear areas throughout the retinoblastoma tissue, with high background noise. Conclusion These findings suggest that CD133 is a potential biomarker for the staging and diagnosis of retinoblastoma in Filipino cancer patients. However, further optimization of the hybridization procedures is recommended.

Background: Among other structures, nuclear grooves are vastly found in papillary thyroid carcinoma (PTC). Considering that the application of artificial intelligence in thyroid cytology has potential for diagnostic routine, our goal was to develop a new supervised convolutional neural network capable of identifying nuclear grooves in Diff-Quik stained whole-slide images (WSI) obtained from thyroid fineneedle aspiration. Methods: We selected 22 Diff-Quik stained cytological slides with cytological diagnosis of PTC and concordant histological diagnosis. Each of the slides was scanned, forming a WSI. Images that contained the region of interest were obtained, followed by pre-formatting, annotation of the nuclear grooves and data augmentation techniques. The final dataset was divided into training and validation groups in a 7:3 ratio. Results: This is the first artificial intelligence model based on object detection applied to nuclear structures in thyroid cytopathology. A total of 7,255 images were obtained from 22 WSI, totaling 7,242 annotated nuclear grooves. The best model was obtained after it was submitted 15 times with the train dataset (14th epoch), with 67% true positives, 49.8% for sensitivity and 43.1% for predictive positive value. Conclusions The model was able to develop a structure predictor rule, indicating that the application of an artificial intelligence model based on object detection in the identification of nuclear grooves is feasible. Associated with a reduction in interobserver variability and in time per slide, this demonstrates that nuclear evaluation constitutes one of the possibilities for refining the diagnosis through computational models.

In March 2020, the Philippine Department of Health (DOH) designed and rapidly implemented a national surveillance system for the utilization of hospital beds by patients with coronavirus disease (COVID-19) to produce complete and timely data for use by various levels of governance in response to the COVID-19 pandemic. The DOH launched the DOH DataCollect (DDC) Bed Tracker system, a web-based application that collects information from all 1906 public and private hospitals and infirmaries across the country using a modular data collection tool. Data on the maximum number of occupied COVID-19-designated beds (n = 28 261), hospital bed utilization rate (71.7%), and mechanical ventilator number (n = 1846) and utilization rate (58.5%) were recorded in September 2021 during the Delta surge of cases in the Philippines. Data on human resources, personal protective equipment and supplies, and other operational indicators were added to the system during various modifications. Information from the DDC was used to inform the COVID-19 response and operations at national and local levels and facilitated research at academic and nongovernmental agencies. The development of the DDC system demonstrates that an effective surveillance system for use by all health-care facilities is achievable through strong national leadership, the use of available technology and adaptive information systems, and the establishment of networks across different health facilities and stakeholders.

Introduction: Non-classical congenital adrenal hyperplasia (CAH) represents a group of inherited, autosomal recessive disor- ders that typically presents with androgenetic alopecia, but may present with alopecia universalis on rare occasions. Case report: We report a case of a 14-year-old Filipino female with non-classical congenital adrenal hyperplasia presenting with alopecia universalis, treated with a combination of Tretinoin and Minoxidil solution, low dose prednisone and an oral supplement containing zinc gluconate, nicotinamide, superoxide dismutase, vitamin E and selenium, with noted gradual hair regrowth and improvement in Dermatology Life Quality Index (DLQI). Conclusion Alopecia universalis in a patient diagnosed with non-classical congenital adrenal hyperplasia is a rare and atypical manifestation, with no case reports available to describe its occurrence. Due to its rarity, there is no standard treatment for pa- tients with this condition. However, the combination of tretinoin and minoxidil solution, low dose prednisone and an oral supple- ment containing zinc gluconate, nicotinamide, superoxide dismutase, vitamin E and selenium shows promising results.

Objective: This study aimed to determine the antimicrobial property of oregano (Plectranthus amboinicus) crude leaf extract against pathogens that infect the throat, specifically Streptococcus pyogenes and Candida albicans using the broth and checkerboard dilution methods.

Methods: This study employed an experimental study design using broth dilution method for the determination of the minimum inhibitory concentration (MIC), minimum bactericidal concentration (MBC) against Streptococcus pyogenes ATCC 19615, and minimum fungicidal concentration (MFC) against Candida albicans ATCC 14053 of P. amboinicus crude extract (PA extract). Checkerboard dilution method was then used for determination of the synergy between PA extract and the standard antimicrobials.

Results: In vitro growth inhibition of S. pyogenes (MIC 0.13 g/mL) and C. albicans (MIC 0.03 g/mL) was exhibited by the PA extract. The highest concentration of PA extract used in this study was not sufficient to demonstrate bactericidal and fungicidal activity (MBC >0.25 g/mL, MFC >0.25 g/mL). Results of checkerboard dilution method revealed that PA extract when combined with either penicillin (for S. pyogenes) or nystatin (for C. albicans) demonstrated indifference.

Conclusion: The crude extract of Plectranthus amboinicus has the capability to inhibit the growth of both S. pyogenes and C. albicans. This demonstrates its potential use in the treatment of throat infections caused by these organisms.
