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.

2.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.

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.

BACKGROUND:
Keloid, a fibroproliferative skin disorder, requires accurate scar assessment. Comprehensive evaluation using a standardized instrument from both patient and observer perspectives is essential to capture its multidimensional impact. This study aimed to translate, culturally adapt, and validate the generic patient and observer scar assessment scale (POSAS) 3.0 into Indonesian for keloid assessment.
METHODS:
A cross-sectional design was adopted following the translation and cultural adaptation guidelines. The instrument was translated into Indonesian by certified translators and administered to 68 keloid patients and 62 dermatologists especially recruited from Pekanbaru and the surrounding areas. Content validity was assessed using the scale-level content validity index average (S-CVI/Ave), construct validity through exploratory factor analysis (EFA), internal consistency with Cronbach’s alpha, test-retest reliability using the intraclass correlation coefficient (ICC), and external validity by correlating the observer scar assessment scale (OSAS) with the modified Vancouver scar scale (mVSS).
RESULTS :
The Indonesian version of the generic POSAS 3.0 demonstrated strong psychometric properties. The S-CVI/Ave was 0.97. The EFA revealed 3 factors for the patient scar assessment scale and two for the OSAS, explaining 71.25% and 73.1% of the variance, respectively. Cronbach’s alpha was 0.79–0.90 and ICC was ≥0.83. External validity was confirmed by a strong correlation with the mVSS (Spearman’s rho = 0.82, p<0.001).
CONCLUSIONS
The Indonesian adaptation of the POSAS 3.0 is a valid and reliable tool for comprehensive keloid scar assessment. Future research should explore the responsiveness to therapeutic interventions.

OBJECTIVES:
Pelvic floor dysfunction is common among pregnant and postpartum women and significantly impacts quality of life. This study aims to translate the German Pelvic Floor Questionnaire for Pregnant and Postpartum Women into Chinese and to evaluate its reliability and validity in the Chinese population.
METHODS:
The questionnaire was translated using the Brislin model. A cross-sectional study was conducted among pregnant and postpartum women to assess the content validity, construct validity, Cronbach's α coefficient, test-retest reliability, and split-half reliability of the Chinese version.
RESULTS:
A total of 72 women were included, with 6.9% being pregnant and 93.1% postpartum; the age was (32.3±3.6) years. The Chinese version of the questionnaire contains 4 dimensions and 45 items. The content validity index of individual items ranged from 0.833 to 1.000, with a scale-level content validity index of 0.977 and intraclass correlation coefficients (ICCs) exceeding 0.90. The overall Cronbach's α coefficient was 0.891, with subscale coefficients ranging from 0.732 to 0.884 (all ICCs>0.70). The test-retest reliability of the total scale was 0.833, and for the 4 dimensions, bladder, bowel, prolapse, and sexual function, the values were 0.776, 0.579, 0.732, and 0.645, respectively. The split-half reliability was 0.74.
CONCLUSIONS
The Chinese version of the questionnaire demonstrated good reliability and validity, indicating its applicability in assessing pelvic floor dysfunction and associated risk factors during pregnancy and postpartum.

Journal of Central South University(Medical Sciences) 2025;50(1):130-142
OBJECTIVES:
Injuries are the leading cause of death among children and adolescents. Although numerous risk assessment tools for unintentional injuries in children have been developed and published both domestically and internationally, there is currently no global consensus on standardized use. This study aims to systematically characterize existing unintentional injury risk assessment tools for children aged 0-6 years, with the goal of informing scientific tool selection and optimization.
METHODS:
Relevant literature published up to January 2025 was retrieved from CNKI, Wanfang, PubMed, and Web of Science. An information extraction form was developed to gather data on the basic features of each assessment tool, assessment format, scoring methods and criteria, dimensions assessed, reliability and validity, and types of unintentional injuries covered.
RESULTS:
A total of 50 risk assessment tools for unintentional injuries among children aged 0-6 years were included. Among them, 35 tools assessed two or more types of unintentional injuries. Regarding assessment format, 38 tools relied on caregiver self-report, 2 on investigator interviews, 3 on direct observation by investigators, and 7 used multiple methods. The tools covered four major dimensions: knowledge, attitude, behavior, and environment. Eleven tools covered 3 dimensions, while only one tool addressed all 4. Nineteen tools provided clear scoring methods, 14 included criteria for risk determination, and only 11 had both scoring methods and risk criteria. Twenty-eight tools lacked both. Twenty-two tools had been evaluated for reliability and/or validity. Among the 25 English-language tools, only 3 had been translated into Chinese.
CONCLUSIONS
Currently, no existing tool comprehensively assesses all major types of unintentional injuries for children under six years of age. It is recommended that practitioners select appropriate tools based on specific needs. In addition, improvements should be pursued, such as translating and validating English-language tools, developing quantitative scoring methods and criteria for tools tailored to Chinese children for important but underrepresented injury types (e.g., road traffic injuries, drowning).

The accurate and timely detection of biochemical coagulation indicators is pivotal in pulmonary and critical care medicine. Despite their reliability, traditional laboratories often lag in terms of rapid diagnosis. Point-of-care testing (POCT) has emerged as a promising alternative, which is awaiting rigorous validation. We assessed 226 samples from patients at the First Affiliated Hospital of Guangzhou Medical University using a Beckman Coulter AU5821 and a PUSHKANG POCT Biochemistry Analyzer MS100. Furthermore, 350 samples were evaluated with a Stago coagulation analyzer STAR MAX and a PUSHKANG POCT Coagulation Analyzer MC100. Metrics included thirteen biochemical indexes, such as albumin, and five coagulation indices, such as prothrombin time. Comparisons were drawn against the PUSHKANG POCT analyzer. Bland-Altman plots (MS100: 0.8206‒0.9995; MC100: 0.8318‒0.9911) evinced significant consistency between methodologies. Spearman correlation pinpointed a potent linear association between conventional devices and the PUSHKANG POCT analyzer, further underscored by a robust correlation coefficient (MS100: 0.713‒0.949; MC100: 0.593‒0.950). The PUSHKANG POCT was validated as a dependable tool for serum and whole blood biochemical and coagulation diagnostics. This emphasizes its prospective clinical efficacy, offering clinicians a swift diagnostic tool and heralding a new era of enhanced patient care outcomes.
