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.

INTRODUCTION

Rabies is a public health concern in the Philippines, where gaps in animal bite prevention and control persist despite national mandates. The One Health approach is a framework which recognizes the interconnectedness of human, animal, and environmental health. Although the Anti-Rabies Act of 2007 aligns with the One Health strategies, its implementation at the local level faced many challenges in coordination, delivery of service, and program sustainability.

OBJECTIVE

This study aimed to determine the factors influencing the acceptability of One Health approach among key stakeholders as a strategy in the prevention and control of animal bites and rabies in the municipality of Alaminos, Laguna.

METHODOLOGY

A qualitative Grounded Theory design was used in the study. Eleven key informants from the provincial, municipal, and barangay levels were interviewed.

RESULTS AND DISCUSSIONCONCLUSION

Thematic analysis of key informants’ responses revealed that, despite limited awareness of the One Health approach, multi-sectoral coordination aids program implementation, although operational gaps remain. Fragmented program delivery, lack of formal training and certification, unclear roles, poor communication, inactive task forces, outdated ordinances, weak enforcement, limited community engagement, and low prioritization of rabies prevention collectively hinder effective implementation.

CONCLUSION

The study highlights the complex challenges of implementing the One Health approach for animal bites and rabies control in rural communities. Effective implementation requires strengthened stakeholder capacity-building and training, enhanced community engagement, improved access to veterinary services, reinforced intersectoral coordination and policy enforcement through revitalized task forces, and ongoing monitoring of progress through vaccination coverage and incidence data.

BACKGROUND

PhilHealth serves as the Philippines’ national health insurance provider and is central to implementing the Universal Health Care (UHC) Law. Despite this, existing gaps and ongoing challenges in claims and financial management systems continue to affect public healthcare facilities’ operations and sustainability.

AIMS AND OBJECTIVES

This article examined the effectiveness and challenges of PhilHealth’s claims and financial management systems in public healthcare facilities, focusing on accreditation, claims processing, reimbursements, and financial governance.

MATERIALS AND METHODS

A qualitative multiple-case study design was employed in Quezon City and the provinces of La Union, Sorsogon, Leyte, and Bukidnon, with data collected from 2022 to 2023. Prior to data collection, a certificate of exemption was granted by the Department of Health – Single Joint Research Ethics Board (DOH-SJREB). Data were collected through key informant interviews with healthcare facility heads, claims processors, and PhilHealth personnel, supplemented by document reviews and facility observations. Thematic analysis was employed to examine the implementation of national health insurance policies at the facility level.

RESULTS

Accreditation standards are uniformly defined, yet compliance varies widely, directly influencing reimbursement outcomes. Facilities with compliance gaps often face provisional accreditation, downgrades, or suspension, resulting in reduced revenue. Although the Universal Health Care (UHC) Law guarantees patient access to PhilHealth benefits, the efficiency of claims processing remains uneven and highly dependent on administrative capacity, staffing adequacy, and digital infrastructure. Systemic inefficiencies at both PhilHealth and facility levels contribute to delays and claim denials. Reimbursements are further constrained by outdated case rate ceilings, inconsistent financial practices, inadequate recordkeeping, weak information systems, and poor storage conditions—particularly in lower-level hospitals and rural health units.

CONCLUSION

Reforms in claims processing workflows, information system integration, and financial management capacities are crucial to enhance reimbursement efficiency. Strengthening these systems is fundamental for supporting sustainable, equitable, and high-quality healthcare delivery in the public sector within the Universal Health Care (UHC) framework.

Climate change is increasingly affecting public health and safety, disproportionately affecting vulnerable populations and aggravating existing health inequities. Recognizing the urgency of this challenge, the Department of Environmental and Occupational Health (EOH), College of Public Health, University of the Philippines Manila, convened the Seventh EOH Forum on November 21–22, 2024, with the theme Resilient Futures: Enhancing Health and Safety in Communities and Workplaces Amid Climate Challenges. This commentary highlights key points raised during the forum, with a focus on community-and workplace-level initiatives that address climate-related health risks. These efforts include the improvement of heat-health early warning systems, integration of climate resilience in occupational health and safety programs, and hospital-based interventions for environmental footprint reduction. The presentations also emphasized the need for multi-stakeholder collaboration, localized mitigation and adaptation strategies, and climate-informed health promotion activities. The forum highlighted that building resilient communities and workplaces requires not only policy alignment and institutional support but also interventions on the ground that are inclusive and equitable.

BACKGROUND

While wearing face shields and other gears to protect the facial mucous membranes not covered by face masks are proven to decrease the odds of infection in the hospital setting, there is no concrete evidence of its efficacy in the general public.

OBJECTIVE

To determine the effectiveness of face shield use in the general public in the local setting.

METHODS

This study utilized an ecological study design, with the weeks when the policy was implemented serving as the exposure variable while the weeks when the policy was not in effect, whether prior to or after, serving as control. Primary outcomes were mean incidence of COVID-19 and case fatality rate (CFR) per week.

RESULTS

When the mandatory face shield use was implemented, the mean incidence of COVID-19 per week was higher compared to weeks when it was not implemented [93 cases per 1000 population per week (ptpw) vs 65 cases, relative risk:1.43, z=-3.79, p=0.0001]. Moreover, during weeks when only less than 50% of the population was vaccinated with first dose (93 cases ptpw vs 52 cases, RR: 1.79, z=-4.3, pCONCLUSIONS

In general, although face shield use increased susceptibility to COVID-19, it decreased case fatality rate in the Philippines. However, a more robust and controlled study in the future may be needed to truly justify its recommendation for the public.
