1.Research advances in the expression and regulation of non-coding RNAs in ischemic stroke
Journal of Apoplexy and Nervous Diseases 2026;43(1):85-91
Ischemic stroke is a cerebrovascular disease with high incidence and disability rates. Non-coding RNAs, as important regulatory factors for gene expression, play a key role in the development and progression of ischemic stroke, but their specific mechanisms of action remain unclear. This article systematically reviews the expression characteristics and regulatory roles of microRNAs, long non-coding RNAs, and circular RNAs in ischemic stroke and reveals the pathophysiological mechanisms of non-coding RNAs in ischemic injury by regulating the processes of cell apoptosis and autophagy, inflammatory response, blood-brain barrier integrity, and neuroregeneration. In addition, non-coding RNAs have shown the potential as biomarkers for the prediction, diagnosis, and prognostic evaluation of ischemic stroke. This article also analyzes the limitations of current research and proposes future research directions, so as to provide a theoretical foundation for exploring the mechanism of action of non-coding RNAs in ischemic stroke and developing innovative diagnostic and therapeutic strategies.

Valacyclovir-associated neurotoxicity (VAN) is a recognized adverse effect in elderly patients with renal impairment but remains underdiagnosed due to its nonspecific presentation and overlap with acute neurologic emergencies. We report a 78-year-old Filipino female with end-stage renal disease on maintenance hemodialysis who developed acute disorientation, agitation, vivid visual hallucinations and generalized weakness shortly after initiation of valacyclovir for herpes zoster. Given the abrupt onset of neuropsychiatric symptoms, viral encephalitis was initially considered. Magnetic resonance imaging of the brain showed no evidence of acute infarction or encephalitis, while electroencephalography demonstrated diffuse generalized slowing consistent with an encephalopathic process. Review of the medication history revealed valacyclovir dosing that exceeded recommendations for patients with end-stage renal disease. Valacyclovir was discontinued and emergent hemodialysis was initiated resulting in marked improvement in sensorium after the second session and complete resolution of symptoms after the third. This case shows VAN as an important diagnostic mimic of acute encephalopathy in elderly patients with renal failure and emphasizes the critical role of early medication review in preventing unnecessary investigations and enabling prompt, reversible management.

BACKGROUND AND OBJECTIVES
Non-Hodgkin Lymphoma (NHL) ranks 11th in cancer incidence and mortality in the Philippines with the combination chemotherapy composed of Cyclophosphamide, Doxorubicin, Vincristine, and Prednisone (CHOP) being commonly used as treatment. However, the addition of Rituximab to CHOP (R-CHOP) has been shown to exhibit higher response rates and longer remissions, potentially improving quality of life. Currently, there is conflicting evidence on the cost-utility of CHOP versus R-CHOP. The study aimed to describe the patient- and country-specific factors, and treatment modalities used for NHL and systematically review cost-utility evidence of R-CHOP versus CHOP in adult NHL patients.
METHODSA systematic literature search of cost-utility studies on R-CHOP versus CHOP for NHL treatment was performed on eight databases: PubMed/MEDLINE, Scopus, Web of Science, EBSCOHost, Cochrane, York Research Database, Centre for Reviews and Dissemination Database, and HERDIN, where 607 studies were identified. Upon screening using an eligibility criteria, 10 studies were included and critically assessed using four appraisal tools: CHEERS, Drummond, Cooper, and ECOBIAS. These were performed independently by two authors with a third author assisting to help reach a consensus.
RESULTSAll studies from high-income countries (HICs) (n=8) and low-middle-income country (LMIC) (n=1) suggested that R-CHOP was more cost-effective for NHL treatment than CHOP in terms of utility outcomes. The study conducted in a low-income country (LIC) (n=1) suggested the opposite, favoring CHOP over R-CHOP. Methodological differences such as perspective, discount rate, willingness-to-pay (WTP), time horizon, and economic model were observed. Methodological limitations include completeness of data reported and credibility of sources used.
CONCLUSIONThe results of this review shall be interpreted with caution as those favoring R-CHOP over CHOP for NHL treatment in terms of cost-utility were concentrated in HICs. More economic evaluations from LICs, LMICs, and upper-middle income countries (UMICs) are needed for a robust conclusion. Additionally, establishing a universally recognized guideline for economic evaluations is essential to guide researchers effectively.

BACKGROUND AND OBJECTIVES
Staphylococcus aureus poses a significant public health threat globally, where both community and hospital-acquired infections are prevalent. The escalating antimicrobial resistance highlights the urgent need for alternative therapies. Hence, traditional medicine using plant extracts offers a potential avenue for novel antibacterial agents. This systematic review aimed to evaluate the existing literature on the antibacterial properties of Philippine plants against S. aureus to provide focus on drug development of a plant-derived antibacterial for this pathogen.
METHODSFollowing PRISMA guidelines, a comprehensive search was conducted in PubMed/Medline, SCOPUS, and Herdin databases. Inclusion criteria encompassed in-vitro studies evaluating the antibacterial activity of crude plant extracts sourced from Philippines plants against S. aureus. Data extraction and quality assessment were performed independently by two reviewers, with discrepancies resolved by the third and fourth reviewers.
RESULTSOf the 413 initial studies identified, nine (9) met the eligibility criteria. The highest zone of inhibition was demonstrated by Lippia micromera L. leaf essential oil at 26.3±1.5 mm, while moderate antibacterial activity was shown by essential oils from Alpinia elegans, Piper quinqueangulatum, and Alpinia cumingii at MIC values of 512 µg/mL, 512 µg/mL, and 1,024 µg/mL, respectively. Other Philippine plants showed a wide range of activity, with MIC values between 50 ?g/mL and 25 mg/mL, MBC values from 78 to 5000 ?g/mL, and ZOI ranging from 5 to 38 mm. However, the overall quality of evidence in these other studies are compromised by bias and incomplete reporting.
CONCLUSIONLeaf essential oils from Alpinia elegans, Piper quinqueangulatum, and Alpinia cumingii demonstrated moderate antibacterial activity against S. aureus. Additionally, the essential oils of Lippia micromera L., Plectranthus amboinicus Lour. Spreng, and Cymbopogon citratus exhibited antibacterial activity against both S. aureus and Methicillin-resistant S. aureus (MRSA) in disk diffusion assays. Majority of the studies gathered had high risk of bias according to the quality assessment criteria tool used in the study. Thus, this systematic review also emphasizes the need for improved methodological rigor on reported in-vitro antibacterial studies.

BACKGROUND
Simulation immerses learners in guided replications of real-life experiences. Simulation-based learning in the health profession allows trainees and professionals to practice skills in a controlled environment using various modalities, enhancing patient safety and minimizing clinical errors.
OBJECTIVETo describe the profile of Philippine studies on clinical simulation in healthcare professional education and assess the methodological quality of these studies.
METHODSWe conducted a scoping review of studies on clinical simulation studies in healthcare education in the Philippines. We followed the methods for scoping review and reported using the PRISMA Scoping review checklist. We searched for relevant studies from electronic databases (PubMed, Scopus, CENTRAL, Herdin, and Cochrane) as of May 17, 2024, and summarized descriptive data on the characteristics of the study, population, clinical simulation technique, and outcomes, using graphical summaries and tables. We assessed the methodological quality of included studies using the Modified Medical Education Research Study Quality Instrument (MMERSQI).
RESULTSWe included 13 studies mostly published in the 2020s (7), by faculty as main author (9), with hospital affiliation (10), single-center (11), setting in NCR (11), analytic (10), medical field (10), educational purpose (7), using task trainers (5), low- to medium-fidelity (11), with technical competencies (mostly skills) as desired outcome (9), median sample size of 40, and including mostly postgraduate level participants (7). There was moderate methodological quality (median MMERSQI score, 51 [range, 40, 77] with the ‘type of data’ item being highly reported and ‘validity of instrument tool’ item poorly reported.
CONCLUSIONThe observed gaps in methodological rigor, study design, and fidelity of simulation techniques in healthcare education in the Philippines highlight opportunities for advancing the field. Future research should aim to address these gaps, particularly by increasing the use of RCTs, enhancing the validity of measurement tools, and incorporating comprehensive simulation components.

BACKGROUND AND OBJECTIVE
Anatomical education utilizes mainly cadaver dissection, but it also depends on innovations such as novel preservation techniques, simulation models, and virtual dissection apps. There is no review on anatomical patents. This study aimed to review the worldwide landscape of existing patents on anatomical education to identify gaps and opportunities for utilization and further innovations.
METHODSWe conducted a scoping review for inventions, utility models, and industrial design applications on anatomical education. We searched the following databases as of December 31, 2022 (WIPO Patentscope, Espacenet, and Derwent). We deduplicated the records, screened them for eligibility, and extracted information on characteristics of the patent application and applicant. We computed frequency and percentage according to country, type of applicant, number of inventors, type of patent, scope of patent, purpose of patent, organ system, status of patent, and time to patent granting.
RESULTSOut of 667 merged records from the initial search, we removed 312 duplicates, excluded 97 records, and included 258 reports in the review. The median number of patent applications per year was 58 (range, 32, 61). Majority of the applications were from China and USA (36.0 and 34.9%, respectively), national in scope (62.8%), industry as applicant (49.6%), inventions (77.5%), usable beyond anatomy (70.9%), physical models (53.1%) and with pending status (63.6%). The median time to granting for 65 patents was 316 days (range, 40 to 1568).
CONCLUSIONFor the period 2018-2022, there were 258 patent applications related to anatomical education, both as a basic science and in clinical applications, were mostly inventions, applied for by industry, contributed by US and China, only national in scope, physical 3D models (mostly musculoskeletal, head/neck and sensory organs, and whole body), and usable beyond basic anatomy. The majority of patent applications are still pending with only 65 granted patents. Plastinated specimens, and the urinary, reproductive, and pulmonary organ system models were least represented.

The Philippine Children’s Medical Center Journal 2025;21(1):27-41
BACKGROUND:
Hospitalization in neonatal intensive care units (NICU) exposes preterm infants to adverse stimuli, including continuous 24-hour lighting. There is currently no standardized NICU layout advised for the best development of preterm neonates. This meta-analysis aimed to assess the impact of cycled light (CL) exposure on clinical outcomes in premature infants admitted to NICU as synthesized in previous studies.
MATERIALS AND METHODS:
This meta-analysis protocol was developed following the preferred reporting items for systematic review and meta-analysis protocols (PRISMA-P) statement. A search was performed in PubMed/MEDLINE, EMBASE, Scopus, and Cochrane databases using the MeSH/key words: ―light exposure‖ AND pre-term AND cycled AND (RCT OR trials OR ―randomized controlled trial). The pooled Mean Difference with corresponding 95% CI was computed for weight gain, duration until start of enteral feeding, and duration of ICU stay using the Mantel–Haenszel random-effect model.
RESULTS:
Nine studies were included. The pooled mean difference showed that among preterm infants who had cycled light exposure, average daily weight gain (MD=6.24 grams, 95%CI=1.36 to 11.13, p=0.01) was significantly higher than those with continuous light exposure. The average time to start enteral feeding (MD=-3.84 days, 95%CI=-7.56 to -0.13, p=0.04) and average ICU stay (MD=-8.43 days, 95%CI=-12.54 to -4.31, p<0.0001) among neonates who had cycled light exposure were significantly shorter.
CONCLUSION
Benefits were seen in preterm infants when exposed to cycled light as opposed to continuous light. CL exposed infants showed a daily weight gain that was 6.24 grams higher, on average, and began enteral feeding nearly 4 days sooner. It led to a decrease in the duration of ICU stay by around 8 to 9 days on average. Further trials to determine the impact of cycled light exposure on morbidity and mortality among preterm neonates is recommended.

The Philippine Children’s Medical Center Journal 2025;21(1):42-55
OBJECTIVE:
Attention Deficit Hyperactivity Disorder (ADHD) is a common mental disorder in children. It is unclear how nutrition and dietary components relate to ADHD. Some studies suggest that children with ADHD have lower serum levels of vitamin D than healthy controls. In the current study, the effects of Vitamin D supplementation on ADHD were reviewed and analyzed using available literature.
MATERIALS AND METHODS:
A meta-analysis and systematic review were performed. Children less than 18 years old diagnosed with ADHD given Vitamin D supplementation or placebo were included. A search was performed in PubMed/MEDLINE, EMBASE, Scopus, Cochrane, and Google Scholar databases from inception to August 2024 using the MeSH keywords: "Vitamin D" AND (ADHD OR Attention Deficit Hyperactivity Disorder) AND (children OR pediatric OR adolescents) AND randomized controlled trial. Standardized Mean Difference (SMD) was used as an effect measure and pooled using random effects meta-analysis.
RESULTS:
The pooled SMS showed significantly lower ADHD scores (SMD=-0.59, 95%CI=-1.06 to -0.11, p=0.01), lower inattentive scores (SMD=-0.61, 95%CI=-1.00 to -0.23, p=0.002), and lower hyperactivity scores (SMD=-0.64, 95%CI=-1.08 to -0.20, p=0.004) in children given Vitamin D supplementation. The adverse events reported were minor only and did not vary significantly between intervention and control groups.
CONCLUSION
Vitamin D treatment as an adjuvant to methylphenidate alleviated ADHD symptoms without significant adverse effects, correlating with enhanced vitamin D levels. Given the robust evidence and well-structured randomized controlled trials, we strongly advocate for the integration of vitamin D supplementation with ADHD treatment.

Philippine Journal of Nursing 2025;95(1):38-49
The way health policies and practices have evolved is largely influenced by translational research, which uses various conceptual and theoretical frameworks to connect evidence with real-world applications. This scoping review had set out to map and to summarize the existing literature on the most used frameworks for turning research into practice and policy. Instead of providing definitive clinical recommendations, it focused on showcasing the current state of evidence to guide future research efforts. To conduct this review, a systematic search was carried out across seven databases, covering peer-reviewed articles, theses, dissertations, and academic literature in health and science. These studies were screened and analyzed following the guidelines set by the Joanna Briggs Institute (JBI). A total of 73 studies were reviewed, encompassing 58 distinct frameworks, with eight emerging as the most frequently applied: CFIR (Consolidated Framework for Implementation Research), ARCC Model (Advancing Research and Clinical practice through close Collaboration), KTA (Knowledge-to-Action) Framework, aSSKINg (Assessing risk, Skin assessment and care, Surface selection, keep moving, Incontinence management, Nutrition, and Giving information ) Framework, CATs (Critically Appraised Topics) Framework, Delphi Technique, HIRAID (History including Infection risk, Red flags, Assessment, Interventions, Diagnostics, communication, and reassessment) Framework, and MRC (Medical Research Council) Framework. The review pinpointed these eight frequently referenced frameworks that served as essential tools for implementing research-informed practices and policies; however, the successful application of these frameworks was affected by various contextual factors, such as the availability of resources, workforce capacity, professional skills, and the suitability of timing and setting. The findings revealed variations in framework orientation, context of application, and stakeholder engagement, highlighting the importance of adaptability, contextsensitivity, and co-design in effective evidence translation. Given the limited range of databases examined, it was suggested that future research should involve a wider and more diverse array of sources to bolster the evidence base and to improve the generalizability of the findings. The review called for greater methodological rigor in framework selection and use, as well as the development of decision-support tools to optimize translational outcomes.

BACKGROUND AND OBJECTIVE
Stigma remains a profound barrier to public health, particularly in managing diseases such as Hepatitis B, which is highly prevalent in hyperendemic regions like the Philippines. The social stigma associated with such health conditions can severely limit access to care and hinder adherence to treatment, exacerbating the overall disease burden. Despite the critical impact of stigma on health outcomes, there is a notable gap in the systematic evaluation of the tools used to measure stigma related to health conditions like Hepatitis B. This study aims to fill this gap by reviewing existing instruments for their methodologies, reliability, and validity to inform the development of a refined tool tailored to the Philippine context.
METHODSA systematic search was conducted across six databases, including PubMed, Cochrane Database of Systematic Reviews, Open Grey, DissOnline, Philippine Health Research Registry (PHRR), and Health Research and Development Information Network (HERDIN), following PRISMA guidelines. The search strategy focused on identifying quantitative and mixed-methods studies using questionnaires to measure HBV-related stigma and discrimination. Studies published between January 1, 1992, and December 31, 2023, were considered. The selection process involved screening for duplicates, reviewing titles and abstracts, and performing a full-text review based on predetermined eligibility criteria.
RESULTSThe initial search yielded 1,198 articles, with 24 duplicates removed. After title and abstract screening, 28 articles were considered for full-text review, resulting in 17 relevant articles in the final analysis with 15 unique instrumentations. The majority of studies employed cross-sectional designs (n=8), with a significant concentration in Asian countries (n=11), indicating a regional focus in HBV stigma research. The review identified a range of questionnaire methodologies, but most studies lacked specificity regarding the type of stigma measured. The Likert Scale was the most commonly used measurement tool, yet few studies provided cut-off values for stigma levels. Validity and reliability testing was reported in 12 articles, including pilot studies, Cronbach’s alpha, and factor analysis.
CONCLUSIONThe lack of a universal methodology and specificity in existing instruments underscores the importance of developing a refined tool that can accurately capture the nuances of stigma and discrimination associated with HBV. The urgent need for standardized, reliable, and culturally sensitive questionnaires is evident, underscoring their importance in developing effective public health strategies and improving treatment outcomes for individuals living with HBV, especially in the Philippines.
