OBJECTIVE: To elucidate the epidemiological characteristics and genetic variant profile of Short-chain acyl-CoA dehydrogenase deficiency (SCADD) among newborns from Hainan Province and evaluate its significance within the local neonatal disease screening panel. METHODS: A total of 84 184 newborns born in Hainan Province from February to December 2024 were included. Tandem mass spectrometry (MS/MS) was employed to detect butyrylcarnitine (C4) and propionylcarnitine (C3) levels in dried blood spots. Screening thresholds were set at C4 > 0.43 μ mol/L and C4/C3 ratio > 0.28. Suspected cases underwent confirmatory testing via urinary ethylmalonic acid analysis by gas chromatography-mass spectrometry and whole-exome sequencing for ACADS gene variants. This study was approved by the Medial Ethics Committee of the hospital (Ethics No.: HNWCMC-2024-55). RESULTS: Six SCADD cases (male-to-female ratio = 1:1) were diagnosed, with all carrying compound heterozygous variants at two loci, yielding a prevalence of 7.13 per 100,000 live births. Four known ACADS gene variants were identified, with both c.322G>A and c.625G>A detected at a frequency of 41.7%. Regular follow-up (as of January 2026) revealed that all diagnosed cases have remained asymptomatic with normal growth and development. CONCLUSION The prevalence of SCADD among newborns in Hainan Province is relatively high, with c.322G>A and c.625G>A as the hotspot variants in the region. Given the absence of clinical phenotypes in all screen-detected cases during long-term follow-up, it is recommended to remove this condition from the routine neonatal screening program for this region to reduce unnecessary anxiety and medical cost.

BACKGROUND AND OBJECTIVES

The global pandemic caused by Coronavirus Disease 2019 (COVID-19) has affected millions, with growing evidence of the potential role of ocular tissues in viral transmission. At the time of writing, local data regarding the phenomenon was limited. This study investigated external ocular manifestations in patients with COVID-19 at a referral center in the Philippines, examined correlations between demographics, systemic manifestations, and laboratory results with ocular manifestations, and determined their timing relative to systemic symptoms.

METHODS

This single-center, descriptive cross-sectional study was carried out from December 8 to 18, 2020 at the adult COVID-19 wards of the Philippine General Hospital involving 72 participants. Data collection involved relevant clinical history taking and performing gross eye examination. The prevalence of ocular manifestations was described with 95% confidence intervals. Correlations between ocular manifestations and quantitative variables were analyzed with point-biserial correlation, and associations with qualitative variables were tested using chi-square or Fisher’s exact tests.

RESULTS

Among participants, 31.9% presented with ocular manifestations with foreign body sensation as the most prevalent ocular symptom (11.1%) and conjunctival hyperemia as the most prevalent ocular finding (19.4%). The median age of patients with ocular manifestations was 41 years old with a higher prevalence in the male population (73.9%, CI=95%, p=0.001). No significant correlation was observed between presence of external ocular manifestations and the different systemic and ocular co-morbidities as well as with COVID-19 clinical classification. Among those who experienced symptoms, majority (29.2%) of the patients experienced systemic symptoms prior to the onset of ocular symptoms. Ocular complaints may present as the sole manifestation (13.9%). Several laboratory parameters were measured and only temperature and AST levels showed a low positive correlation with the presence of ocular manifestations. 

CONCLUSION

Ocular manifestations occur in roughly one third of patients with COVID-19 based on this study population. With some individuals presenting with ocular signs or symptoms as the initial and sole manifestation, healthcare practitioners must exercise caution and remain vigilant in managing patients who present as such. At the time of writing, this is the first local study investigating the different external ocular manifestations in patients with COVID-19. There is a need to pursue more robust studies and conduct more local investigations which will guide both ophthalmologists and other practitioners in strengthening existing guidelines regarding precautionary practices, clinical diagnosis, and management of COVID-19 patients.

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.

METHODS

The 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.

RESULTS

The 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.

CONCLUSION

Among 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.

Bullous hemorrhagic dermatosis (BHD) is a rare cutaneous manifestation characterized by tense hemorrhagic bullae that appear at sites distant from low molecular weight heparin (LMWH) injections, typically within seven days of exposure. As of March 2022, only 94 cases have been reported. It most commonly affects elderly males with predisposing factors for thromboembolism, such as carcinoma, and usually involves the extremities.

This case highlights the importance of maintaining a high index of suspicion for bullous hemorrhagic dermatosis (BHD) in patients receiving low molecular weight heparin, even beyond the typical 7-day window and in demographics not commonly affected. Early recognition and prompt discontinuation of the offending agent, as demonstrated in this atypical presentation involving a Filipino elderly woman with multiple comorbidities and no malignancy, can lead to favorable outcomes. Clinicians should be aware of this rare but reversible complication to avoid misdiagnosis and ensure appropriate management.

BACKGROUND

Type 2 diabetes is the most common type of diabetes in the Philippines. Diabetic foot complications represent a prevalent and significant chronic concern for individuals with type 2 diabetes. This poses an immediate community health concern, as diabetic complications may threaten an individual's well-being.

OBJECTIVE

This study intends to cross-culturally adapt the Diabetic Foot Knowledge Subscale (DFKS) and Foot Self-Care Behavior Scale (FSCBS) questionnaires into the Filipino language as an assessment tool among Filipinos with diabetes.

METHODS

The study employed a psychometric research design, where it entailed Phase A and Phase B. Phase A involved the forward translation of the DFKS and FSCBS questionnaires, followed by the synthesis of the translations and backward translation. Subsequently, an expert committee reviewed the translations and concluded the final version. The final translated versions of the questionnaires ensured that it can be understood by an individual who has a Grade 6 level of reading proficiency. Phase B entailed the validity testing with the evaluation of the expert committee, and reliability testing of the said questionnaires with a sample size of 30 participants. A wash-out period of 24 hours was given for the test-retest reliability, followed by data analysis. The validity and reliability of the questionnaires were measured using the item and scale content validity indices and the internal consistency and test-retest reliability, respectively, to ensure their accuracy and appropriateness. The content validity of the questionnaires was evaluated individually by the experts using a Likert scale from 1-4, with 4 being the highest meaning the item was very relevant and succinct. Scores per item were between 3 and 4, which indicate that the translated version of the items were relevant and succinct or were relevant but needed minor revisions.

RESULTS

The validity scores for the translated DFKS and FSCBS questionnaires were obtained using the Scale Content Validity Index (S-CVI) with a score of 0.96 and 0.92, respectively. Moreover, all items in the questionnaires obtained an Item Content Validity Index (I-CVI) of 0.88-1.00. The DFKS also has an acceptable internal consistency with a Cronbach’s alpha of 0.72, while the FSCBS has a good internal consistency with a Cronbach’s alpha of 0.85. The test-retest reliability shows an acceptable Spearman’s correlation at 0.76 for the DFKS and a strong positive Pearson correlation coefficient at 0.73 for the FSCBS.

CONCLUSION

The validity of the two questionnaires was acceptable and the test-retest reliability showed a strong positive correlation among the items thereby making the cross-cultural adaptation of the questionnaires successful. The Filipino versions of the DFKS and FSCBS questionnaires accurately measure the knowledge and behavior of individuals with type 2 diabetes, respectively.

BACKGROUND

Public health nurses (PHNs) are a significant cadre of the primary healthcare workforce working toward achieving universal health care (UHC). Exploring their work activities is integral to understanding how UHC is implemented better.

OBJECTIVES

To describe and explore the work activities, roles, and functions of the PHNs in rendering primary care services in the context of UHC.

METHODS

Key informant interviews were conducted with 12 PHNs in Tarlac Province who were working with permanent status in their respective rural health units (RHUs) for at least 1 year. They were selected through selection criteria. Data were recorded, transcribed, and subjected to thematic analysis.

RESULTS

Data analysis led to the emergence of 4 themes and 11 subthemes. The four themes were: (a) evolving scope and nature of work, (b) work challenges and barriers toward UHC implementation, (c) UHC outcomes, impact, and insights, and (d) communication and health promotion.

CONCLUSIONS

The study underscores the importance of exploring the PHNs’ roles and functions, as it offers a window on how they fulfill their duties toward achieving the goals of UHC. From the viewpoint of the interviewed PHNs, several elements and issues need to be addressed. Consequently, some positive impact on their work activities and functions emerged. Their nature of work brought them professional development and fulfillment as they render primary care and value-driven services despite the challenges and struggles they encountered in public health.

BACKGROUND

Groundwater is an essential resource for domestic use, agricultural needs, and economic activities, yet it is increasingly threatened by contamination and overextraction. To evaluate groundwater quality and identify associated health risks, the Philippine Groundwater Health Index (PGHI) project conducted a comprehensive assessment of selected sites across various regions in the country.

METHODS

The study analyzed groundwater samples from multiple locations to determine compliance with the Philippine National Standards for Drinking Water. Parameters assessed included organochlorines, heavy metals, microbial indicators, and physical and nonmetal characteristics such as phosphate and ammonia levels. Results were compiled to evaluate overall groundwater safety and identify areas of concern.

RESULTS

No organochlorines were detected in any of the samples, and all heavy metals complied with national drinking water standards. However, significant noncompliance was observed in other parameters. Microbial contamination was widespread, with 79.25% of samples failing to meet microbial standards due to the presence of fecal coliforms and Escherichia coli. Elevated levels of physical and nonmetal parameters were also noted, with 21 of 27 sites exceeding phosphate limits and 8 sites exceeding ammonia levels. These findings indicate substantial health risks associated with fecal contamination and nutrient pollution.

CONCLUSION

The PGHI project underscores the urgent need for enhanced groundwater treatment processes, regular monitoring, and strengthened policy-making to ensure safe drinking water. While the study provides critical insights, limitations such as lack of seasonal data, absence of emerging contaminant analysis, and limited spatial coverage highlight the necessity for continued improvements in groundwater management. Addressing these gaps is essential to protect public health, preserve environmental quality, and ensure the sustainable availability of safe groundwater for future generations.

INTRODUCTION

Heart failure (HF) remains a significant global health issue, affecting approximately 64 million individuals worldwide. In the Philippines, the prevalence aligns with global estimates, disproportionately affecting older populations.

METHODOLOGY

The Philippine National Heart Failure Network (PNHFN) conducted a cross-sectional survey from November 2021 to March 2022 to assess the landscape of HF management among medical professionals across the country.

RESULTS

A total of 1,649 physicians responded, primarily cardiologists (64%), internal medicine specialists (27%), and general practitioners (12%). While diagnostic tools such as electrocardiography (92%) and 2D echocardiography (85%) were widely available, advanced imaging modalities and specialized cardiac procedures, including cardiac catheterization and heart failure implantable devices, were less accessible outside metropolitan areas. Essential HF medications, including renin-angiotensin system blockers (84%), beta-blockers, and diuretics, were commonly prescribed; however, newer pharmacologic options such as sodium-glucose co-transporter 2 inhibitors remained underutilized.

CONCLUSION

Cardiac rehabilitation was accessible to less than half of respondents (48%), with unavailability cited as a major barrier. Despite these challenges, 97% of participants supported the establishment of HF programs to improve patient care and provider support. The findings highlight the need for improved access to advanced diagnostic and therapeutic modalities, enhanced education on guideline-directed HF management, and expanded infrastructure to bridge gaps in care delivery. Strengthening national HF initiatives and fostering collaboration among stakeholders are crucial in optimizing HF management and patient outcomes in the Philippines.

BACKGROUND AND OBJECTIVE

The Philippine Inter-Agency Task Force for the Management of Emerging Infectious Diseases implemented health protocol guidelines to reduce the risk of COVID-19 transmission. Individuals with comorbidities were advised to take precautionary measures due to their increased vulnerability. This study aimed to assess the relationship between knowledge, acceptance, and adherence to health protocols among fully vaccinated individuals with comorbidities in the National Capital Region, Philippines.

METHODS

The study employed an explanatory-sequential mixed-method design. The quantitative phase involved an online survey with 384 respondents. The survey included questions on socio-demographic profile, COVID-19 knowledge, acceptability of health protocols, and adherence to preventive practices. Chi-square Test of Independence and Pearson’s Correlation Test were used to analyze the data. Semi-structured interviews were conducted with 11 participants, providing rich insights into their personal experiences. The interview transcripts were analyzed using Colaizzi’s descriptive method with the aid of qualitative analysis software (MAXQDA), ensuring a rigorous approach to thematic analysis. The integration of the two phases was achieved by connecting quantitative results with qualitative insights, creating a comprehensive understanding of the phenomena under study.

RESULTS

Findings showed that the relationship of sociodemographic characteristics and level of knowledge (Gender pCONCLUSION

The study suggests that multiple factors contribute to non-adherence to health protocols. Recognizing these holes and weaknesses in the COVID-19 pandemic response stresses the need for national leaders to place urgency on properly implementing preventive measures and providing health education to the masses during public health situations. Collaboration from all sectors is crucial in addressing public health crises. This study can be a valuable resource for future researchers, local government units, and policymakers in prioritizing public health care and pandemic preparedness.
