1.From data to practice: Why translating research findings to real-world outcomes needs more implementation studies.
Acta Medica Philippina 2026;60(8):5-6
Walking through the wards of a crowded public hospital and seeing suffering and tragedy from easily preventable conditionsmakes one wonder what it takes for a facility to change the outcomes. The evidence is there, and guidelines have beendeveloped from it; yet practices remain difficult to change—whether in screening, prevention, treatment, or rehabilitation.
Recently, the Department of Health has put up a compendium of clinical practice guidelines (CPG) crafted accordingto the standards set by the Manual for Clinical Practice Guideline Development of DOH-Philhealth.Guidelines stipulatethat dissemination and implementation be considered, and applicability issues are discussed. The uptake of the guidelinesshould be evaluated, and facilitators and barriers should be identified. Thus, there is a need for implementation andapplicability studies to assess how effective guidelines are. For breast cancer, the Philippine Guidelines were published in 2022and updated in 2026.Identified as barriers against implementation are financial constraints and out-of-pocket costs. Actahas since responded to these concerns by publishing articles on financing cost assessment, and in this issue, by Mondragonand co-authors, an “Assessment of Out-of-Pocket Expenditure of HER2-Positive Breast Cancer Patients in a Tertiary CancerCenter and Private Clinics in the Philippines.”
These types of studies are necessary in the translation of evidence to practice, allowing organizations to adopt, scale,and sustain recommendations to real-world settings.
Where CPGs on malnutrition cite resource constraints as the only significant barrier for implementation, the article byde Luna and co-authors on the “A Qualitative Program Evaluation Study on the Perceived Impact of Health and NutritionPrograms among Beneficiaries of a Civil Society Organization in the Philippines” in this issue of the Acta add fear ofsustainability by families and competition from readily accessible instant food of poor nutritional value as barriers in implementingsuch programs.
These studies help us go beyond information dissemination of evidence-based practice to create pathways for impactfulintegration of recommended interventions. Implementation studies sharpen our analysis and focus our efforts on strategies thatcan help pilot, roll out, and scale up guidelines.
New modalities to carry out recommendations can also be part of how guidelines are implemented in the communitysetting. Where the Philippine Academy of Rehabilitation Medicine (PARM) recommends early home-based rehabilitation,the Stroke Society of the Philippines recommends telerehabilitation to augment the efforts of care providers.The articleby Laxamana and co-authors in this issue on “The Acceptance of Stroke Telerehabilitation among Rehabilitation Providersand Consumers in Two Tertiary Hospitals in the Philippines” not only identifies but also provides suggestions to addressimplementation barriers.
We support and encourage articles on implementation science. These works provide tools to convert evidence into outcomes.These transform organizations and help us accomplish meaningful, lasting structural change that should come withoutany delay to provide relief to our patients in our crowded public wards.

BACKGROUND
Undernutrition remains a public health concern in the Philippines despite multitude of government efforts using different nutrition specific and sensitive interventions. Hence, the role civil society organizations play is important in augmenting the health and nutrition programs in the country. Community feedback is important as they are the receiving end of these programs.
OBJECTIVEThe study aimed to know the perceived impact and community insights on the implemented health and nutrition programs in the four selected sites in the Philippines.
METHODSQualitative program evaluation was used, and 50 discussants were recruited through purposive sampling. Semi-structured interview guide for focus group discussion was utilized to determine the perceived impact of the programs among the discussants, and thematic analysis was used to generate codes and themes.
RESULTSThe implemented health and nutrition programs were found to be a source of hope for the family and community and beyond basic necessities. However, there remain barriers in successful acquisition of new information such as a lack of resources and environmental influences. There are also learned opportunities such as continued support from the Civil Society Organization (CSO), and impact capacity building that are not sponsor-driven.
CONCLUSIONOverall, the participants see the health and nutrition programs as helpful for their children as these programs foster proper child rearing. The programs also empower the parents and the community through capacity building. However, there is a need to revisit implementing rules and guidelines to further maximize the benefits and resources of the programs.

BACKGROUND AND OBJECTIVE
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) as the causative agent of COVID-19 has significantly challenged the public health landscape in late 2019. After almost 3 years of the first ever SARS-CoV-2 case, the World Health Organization (WHO) declared the end of this global health emergency in May 2023. Although, despite the subsequent drop of COVID-19 cases, the SARS-CoV-2 infection still exhibited multiple waves of infection, primarily attributed to the appearance of new variants. Five of these variants have been classified as Variants of Concern (VOC): Alpha, Beta, Gamma, Delta, and the most recent, Omicron. Therefore, the development of methods for the timely and accurate detection of viral variants remains fundamental, ensuring an ongoing and effective response to the disease. This study aims to evaluate the feasibility of the application of an in-house approach in genomic surveillance for the detection of SARS-CoV-2 variants using in silico designed primers.
METHODSThe primers used for the study were particularly designed based on conserved regions of certain genes in the virus, targeting distinct mutations found in known variants of SARS-CoV-2. Viral RNA extracts from nasopharyngeal samples (n=14) were subjected to quantitative and qualitative tests (Nanodrop and AGE). Selected samples were then analyzed by RT-PCR and amplicons were submitted for sequencing. Sequence alignment analysis was carried out to identify the prevailing COVID-19 variant present in the sample population.
RESULTSThe study findings demonstrated that the in-house method was able to successfully amplify conserved sequences (spike, envelope, membrane, ORF1ab) and enabled identification of the circulating SARS-CoV-2 variant among the samples. Majority of the samples were identified as Omicron variant. Three out of four designed primers effectively bound into the conserved sequence of target genes present in the sample, revealing the specific SARSCoV-2 variant. The detected mutations characterized for Omicron found in the identified lineages included K417N, S477N, and P681H which were also identified as mutations of interest. Furthermore, identification of the B.1.448 lineage which was not classified in any known variant also provided the potential of the developed in-house method in detecting unknown variants of COVID-19.
CONCLUSIONAmong the five VOCs, Omicron is the most prevalent and dominant variant. The in-house direct PCR product sequencing surveillance (DPPSS) method provided an alternative platform for SAR-CoV-2 variant analysis which is accessible and affordable than the conventional diagnostic surveillance methods and the whole genome sequencing. Further evaluation and improvements on the oligonucleotide primers may offer significant contribution to the development of a specific and direct PCRbased detection of new emerging COVID-19 variants.

OBJECTIVES
This study aimed to evaluate the psychometric properties of the Tagalog version of the PsAQoL to assess its reliability and consistency.
METHODSThis is a prospective validation study involving 47 patients with PsA from June to August 2023. The
psychometric properties tested were internal consistency (Cronbach’s alpha coefficients), test-retest reliability, convergent validity (Spearman’s rank correlation), and known group validity (Mann-Whitney U Test or Kruskal- Wallis One-Way Analysis of Variance).
The PsAQoL on both week 0 and week 2 had Cronbach’s alpha coefficients of 0.926 indicating high
internal consistency. Test-retest reliability was 0.929, which demonstrates excellent reliability and low level of random measurement error. The PsAQoL scores highly correlated with the Health Assessment Questionnaire-Disability Index (r=0.754, pCONCLUSION
The Tagalog version of the PsAQoL demonstrates excellent psychometric properties and is recommended for monitoring of Tagalog-speaking patients with psoriatic arthritis in healthcare settings.

OBJECTIVES
Clinical pathways (CPs) ensure adherence to heart failure (HF) management guidelines. To optimize quality care in a low resource setting, an evidence-based care pathway for the management of acute HF was implemented at the emergency department (ED) of the Philippine General Hospital (PGH), the designated national tertiary hospital and referral center. This study aimed to describe the characteristics of adults with acute HF admitted at the ED and evaluate the quality of care they received, measured using physician adherence to the hospital’s acute heart failure CP.
METHODSThis was a retrospective, descriptive cohort study. We reviewed the inpatient charts of all adult patients with acute HF admitted to the ED of the PGH and referred to the Division of Cardiovascular Medicine between December 1, 2022 and May 31, 2023. Quality of care was assessed based on adherence to quality indicators adapted from routine and conditional order sets detailed in the pathway. Descriptive statistics was utilized to describe patient characteristics, quality of care, and outcomes.
RESULTSTwo hundred thirty-six (236) patients were included, with a mean age of 51.8 years. Majority were male (53.4%); hypertension (61.4%) and ischemic heart disease (53.8%) were the most common comorbidities, and infection the most common precipitant of decompensation (60.6%). There were optimal adherence rates to routine orders, which included referrals to Internal Medicine and Cardiology, baseline vital signs monitoring, fluid intake and output monitoring, chest radiograph, complete blood count, blood urea nitrogen, sodium, potassium, prothrombin time, partial thromboplastin time, arterial blood gas, urinalysis, and N-terminal pro b-type natriuretic peptide. Conditional orders, such as oxygen support, focused echocardiography, thyroid - stimulating hormone, and the use of vasopressors, diuretics, and venous thromboembolism prophylactic agents, were optimally performed when warranted. However, we noted suboptimal adherence to certain resource-intensive conditional orders, such as hourly monitoring of urine output (61.4%), hooking to cardiac monitor (53.8%), and performance of 12-lead ECG within 10 minutes (56.8%). Further, only 43.9% of patients were referred to the intensive care unit. Troponin I, calcium, magnesium, and albumin were ordered in excess.
CONCLUSIONOverall adherence rate of physicians to the hospital’s Acute Heart Failure Pathway was satisfactory. Work is needed to improve adherence to hourly urine output monitoring, consistent hooking to cardiac monitor, and timely performance of 12-lead ECG – an effort that begins with expanding in-hospital diagnostic equipment and human resource supply. We recommend continuous pathway implementation with periodic evaluation and stakeholder feedback to further improve quality of care.

BACKGROUND
In the Philippines and other developing countries, access to high-stability external fixators for traumainduced bone fracture management is limited, as modular external fixators, especially those with snap-on features, are manufactured overseas and are prohibitively expensive for most Filipino patients.
OBJECTIVEThis study aimed to assess the biomechanical performance of a locally-developed modular external fixator prototype for tibial diaphyseal fractures in comparison to available external fixators, such as Roger Anderson and Hoffmann. This provides an initial evaluation for the use of the external fixator as an alternative in terms of its stability.
METHODSUsing axial compression testing compliant with the ASTM F1541-24 standards, the ultimate strength, yield strength, safe strength, and stiffness were measured across various fixator types and tightening mechanisms, with or without the aid of a wrench. Statistical tools such as the t-test assuming equal variances, one-way analysis of variance, and Tukey-Kramer test with a 0.05 level of significance were used to determine any significant differences.
RESULTSThe mechanical performance of the external fixator prototype increased by a factor of 1.5 to 2.5 after the clamps were tightened with the wrench. However, when hand-tightened, it still performed sufficiently, showing a comparable mechanical performance with the Roger Anderson Fixator. In terms of the ultimate, safe, and yield strengths, it performed competitively in comparison with the Hoffmann system. However, there is a significant difference in stiffness between the prototype and the Hoffmann system.
CONCLUSIONThe locally-developed external fixator was comparable biomechanically to the commercially available external fixators and the prototypes in different studies.

OBJECTIVES:
To explore the therapeutic mechanism of Guizhi Fuling (GZFL) Pellets against cervical cancer.
METHODS:
Publicly available databases were used to identify the targets of GZFL Pellets and cervical cancer to construct the protein-protein interaction (PPI) network, followed by GO biological process and KEGG pathway enrichment analysis of the hub genes. The "Traditional Chinese Medicine-Active Ingredients-Targets-Pathways" network for GZFL Pellets in cervical cancer treatment was generated using Cytoscape v10.0.0, and molecular docking of the drug and potential targets was performed to predict the specific targets of active components in Guizhi Fuling Pellets. The inhibitory effects of hederagenin, an active ingredient in GZFL Pellets, was tested in cultured cervical cancer cells and in nude mice bearing cervical cancer xenografts.
RESULTS:
GZFL Pellets contain 338 active components targeting 247 action sites. A total of 10127 cervical cancer-related targets were obtained, and among them 195 were identified as potential therapeutic targets of GZFL Pellets for cervical cancer treatment, including the key targets of GABRA1, PTK2, JAK2, HTR3A, GSR, and IL-17. Molecular docking study showed low binding energies of the active components such as hederagenin, campesterol, and stigmasterol for protein-molecule interaction. GO enrichment analysis suggested that GZFL Pellets inhibited cervical cancer primarily by regulating responses to steroid hormones, oxidative stress, and lipopolysaccharides. Among the active components of GZFL Pellets, hederagenin was found to inhibit cervical cancer cells in vitro and significantly reduced STAT3 phosphorylation level in the cancer cells. In nude mice bearing cervical cancer xenografts, hederagenin effectively inhibited tumor growth rate without causing obvious adverse effects.
CONCLUSIONS
GZFL Pellets inhibit cervical cancer cell growth through its multiple active components that target different pathways. Among these components, hederagenin inhibits tumor cell growth possibly by directly binding to JAK2 protein to inhibit STAT3 phosphorylation.

OBJECTIVES:
To investigate the inhibitory effect of pirfenidone (PFD) on growth of bladder cancer xenograft and its regulatory effect on Treg cells in tumor-bearing mice.
METHODS:
Thirty-two C57BL/6 mice bearing ectopic bladder tumors were randomized into control and PFD groups (n=16). In PFD group, PFD was administered orally at the daily dose of 500 mg/kg, and tumor growth and survival of the mice were monitored. After treatment for 21 days, the tumors and vital organs were harvested for analysis. Immunohistochemistry was used to assess CD3, CD4, CD8, and FOXP3 expressions in the tumors. Flow cytometry and RT-qPCR were used to analyze the percentage of CD4⁺CD25⁺FOXP3⁺ Treg cells and IL-2, IL-10, and IL-35 expressions in the tumors and spleens; organ damage of the mice was examined with HE staining.
RESULTS:
Compared with the control group, the PFD-treated mice exhibited significantly lower tumor growth rate with smaller tumor volumes at day 21, along with improved survival at day 28. Immunohistochemistry revealed no significant differences in the infiltration of CD3⁺ and CD8⁺ cells between the two groups, but the percentages of CD4⁺ and FOXP3⁺ cells were significantly lower in the tumors of PFD-treated mice. Flow cytometric analysis confirmed a decrease in CD4⁺CD25⁺FOXP3⁺ Treg cells in the tumors from PFD-treated mice, which also had reduced expression levels of IL-2, IL-10 and IL-35 mRNAs in the tumors. No significant differences were found in Treg cell populations or cytokine expressions in the spleen tissues between the two groups. HE staining showed obvious organ damage in neither of the groups.
CONCLUSIONS
PFD inhibits bladder cancer growth and enhances survival of tumor-bearing mice possibly by suppressing Treg cells in the tumor microenvironment.

9.The modified Chinese version of Wong and Law Emotional Intelligence Scale for measurement of emotional health: revision and psychometric evaluation.
Journal of Southern Medical University 2025;45(10):2191-2198
OBJECTIVES:
To revise and evaluate the psychometric properties of the Chinese version of the Wong and Law's Emotional Intelligence Scale (WLEIS).
METHODS:
The 11 items of the original WLEIS were modified to form the WLEIS-CR, with the Generalized Anxiety Disorder Scale (GAD-7), 9-item Patient Health Questionnaire (PHQ-9), and Flourishing Scale (FS) as the validity criteria. A total of 1546 adult participants were evaluated using all these scales, and a retest was conducted among 192 college students to assess the item discrimination, reliability, validity and measurement invariance of the modified WLEIS-CR.
RESULTS:
All the 16 items of the modified WLEIS-CR demonstrated good discriminative power (r=0.570 -0.764, P<0.001). The structural equation model from a confirmatory factor analysis showed excellent fit indices (χ²/df=4.610, GFI=0.965, PGFI=0.674, RMR=0.028, NFI=0.975, CFI=0.980, RMSEA=0.048). The criterion-related validity of the modified WLEIS-CR with FS, GAD-7, and PHQ-9 was 0.674, -0.347, and -0.368, respectively (P<0.001). The internal consistency (Cronbach's α) was 0.913 for the total scale and ranged from 0.867 to 0.916 for the subscales. The split-half reliability was 0.956 for the total scale and 0.865-0.924 for the subscales. Test-retest reliability was 0.701 for the total scale and 0.610-0.684 for the subscales. Normative interpretation criteria were established: 7.6% of participants had "low", 19.3% had "below average", 22.3% had "moderate", 34.3% had "above average", and 16.5% had "very high" emotional intelligence. The scale demonstrated a good measurement invariance across gender, identity, and age groups.
CONCLUSIONS
The modified WLEIS-CR has good reliability, validity and measurement invariance, and is suitable for evaluating emotional intelligence of Chinese adults to assess their emotional health.

OBJECTIVES:
To investigate the molecular mechanism by which Lichong Xiaozheng Granules (LCXZ) sensitize ovarian cancer to cisplatin (DDP) treatment.
METHODS:
LC-MS analysis was used to identify the blood components of LCXZ after its administration in mice via gavage. In a BALB/c mouse model bearing subcutaneous ovarian cancer xenografts, the effects of daily gavage of distilled water (control group), intraperitoneal injection of DDP (5 mg/kg) once a week, or both DDP injection and daily LCXZK gavage (15 g/kg) on tumor growth were evaluated. Histopathological changes in the xenografts and kidneys were assessed with HE staining. RNA-seq was performed to identify the differentially expressed genes followed by KEGG pathway analysis. The changes in mitochondrial ultrastructure and expressions of mitochondrial apoptosis-related were examined with transmission electron microscopy and Western blotting.
RESULTS:
A total of 218 blood-borne components of LCXZ were detected by LC-MS. In the tumor-bearing mice, treatments with DDP and DDP combined with LCXZ redcued the tumor volume by 60.3% and 72.6% compared with that in the control group, respectively. Transcriptomic analysis revealed significantly upregulated ANT3 expression in both the two treatment groups. Molecular docking indicated that the main active components of LCXZ were capable of binding to adenine nucleotide translocator 3 (ANT3) with binding energies below -6 kcal/mol. Transmission electron microscopy showed obvious mitochondrial swelling and outer-membrane damage in the tumor cells in DDP-treated mice, and these changes were more pronounced in the combined treatment group. The expression levels of BAX, ANT3, cleaved caspase-3 and cleaved caspase-9 were increased, whereas BCL-2 expression was decreased significantly in the tumor cells in both the DDP and DDP+LCXZ groups.
CONCLUSIONS
LCXZ enhances the therapeutic efficacy of cisplatin against ovarian cancer xenografts in mice by promoting mitochondrial dysfunction and activating apoptotic signaling pathways via upregulating ANT3.
