OBJECTIVES

Timely access to appropriate levels of care is essential for improving maternal, newborn,
and child health outcomes. To address persistent service delivery fragmentation and strengthen referral systems, the Philippine Department of Health issued Administrative Order 2020-0019 to guide the design of Health Care Provider Networks (HCPNs) under the Universal Health Care Act of 2019. This study assessed the extent to which sixteen municipalities across four provinces in Eastern Visayas comply with the HCPN service delivery guidelines in the context of maternal and newborn care.

METHODS

The study employed a descriptive cross-sectional mixed-methods design, utilizing structured facility checklists to assess compliance with HCPN standards. Qualitative data were gathered through key informant interviews and focus group discussions with purposively selected stakeholders—decision makers, health personnel, and mothers—to contextualize findings. A three-lever framework for integrated care (policy, operational, and cross- cutting) guided the analysis

RESULTS

The findings revealed significant gaps between the current capacities of study health facilities and the requirements outlined in the HCPN guidelines. Major gaps included (1) weak cooperative governance mechanisms to support network-wide coordination; (2) limited systematic linkages between facilities, including fragmented referral protocols and non-interoperable health information systems; (3) inadequate investments in infrastructure, health human resources, and medical commodities; and (4) absence of performance monitoring systems across HCPNs.

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.

Asthma is a chronic respiratory disease characterized by persistent airway inflammation and irreversible airway remodeling. Current treatment strategies primarily rely on symptom relievers and controllers, which do not fundamentally modify the underlying disease pathology, and thus asthma has long been regarded as being difficult to cure. However, long-term follow-up studies in various cohorts have reported sustained absence of symptoms, or clinical remission. In pediatric asthma, several birth cohort studies have demonstrated clinical remission rates approaching 50%, and even in disease cohorts applying more stringent diagnostic criteria, remission has been still observed in children. Higher remission rates have been reported in individuals with younger age at onset, male sex, nonatopic phenotypes without sensitization to inhalant allergens, preserved lung function, and lower bronchial hyperresponsiveness. Immunotherapy, which can modify the natural course of allergic diseases, has been shown to reduce bronchial hyperresponsiveness and increase remission rates in asthma. Recently, the development and widespread use of biologics have enabled remission to be considered as a therapeutic goal even in severe asthma, prompting efforts to standardize its definition. In the current era of diverse therapeutic options and improved clinical outcomes, establishing both more precise and practical evaluation and definition of asthma remission will be pivotal for achieving personalized and precision asthma management.

Purpose: Laryngomalacia exhibits diverse morphological patterns, severities, and comorbidities. Defining clinical phenotypes could improve management and prognosis. This study aimed to identify and characterize phenotypes using cluster analysis and to evaluate prognostic factors. Methods: We retrospectively reviewed records of 195 children diagnosed with laryngomalacia between 2014 and 2023 using flexible laryngoscopy or bronchoscopy. Demographics, endoscopic findings, comorbidities, and outcomes up to 1 year of age were collected. Hierarchical cluster analysis was conducted using 10 clinical variables. Results: Four phenotypes emerged: cluster 1 (n= 75, 38.5%), Groningen Laryngomalacia Classification System (GLCS) type 1 dominant-mild; cluster 2 (n= 35, 17.9%), GLCS type 2 dominant-mild; cluster 3 (n= 40, 20.5%), severe with multiple comorbidities; and cluster 4 (n = 45, 23.1%), GLCS combined-type moderate. Distinct clinical courses were observed. Cluster 3 showed the highest rates of surgical intervention (32.5%, P < 0.001), pediatric intensive care unit admission (17.5%, P = 0.016), and Emergency Department (ED) visits (60.0%, P= 0.013) for respiratory problems during the first year. When stratified by comorbidities, children with multiple comorbidities, particularly those with major feeding problems had a higher risk of hospitalization (adjusted odds ratio [aOR], 2.65;95% confidence interval [CI], 1.11–6.33) and ED visits (aOR, 3.17; 95% CI, 1.39–7.23), even after adjusting for sex and severity. Conclusion Four clinically meaningful phenotypes of laryngomalacia were identified from the cluster analysis based on morphology, comorbidities, and disease severity. Children with multiple comorbidities accompanied by feeding problems had the greatest risk of hospitalization and ED visits for respiratory problems within the first year, even after adjusting for the severity of laryngomalacia.

Hypersensitivity reactions (HSRs) to iodinated contrast media (ICM) can range from mild cutaneous symptoms to life-threatening anaphylaxis. In patients with a history of ICM hypersensitivity, avoidance of the culprit agent is generally recommended. This case report describes a successful desensitization in a 56-year-old man with recurrent HSRs to multiple agents including ioversol, iohexol, iobitridol, and iopamidol. Intradermal testing was performed to identify potentially safe alternatives; however, all tested agents, including iohexol, ioversol, iobitridol, iopamidol, iodixanol, iomeprol, and iopromide, yielded positive results. Given the clinical necessity of transcatheter arterial chemoembolization, a 13-step rapid desensitization protocol with iodixanol was implemented. The procedure was completed without any breakthrough reactions. This case highlights desensitization as a feasible and effective strategy for patients with hypersensitivity to multiple ICM agents.

Diffuse alveolar hemorrhage (DAH) is a rare but life-threatening condition characterized by bleeding into the alveolar spaces because of damage to the pulmonary microvasculature. While it is commonly associated with autoimmune or coagulation disorders, post-ictal DAH following a generalized tonic-clonic seizure is extremely rare, especially in pediatric populations. We report the case of a previously healthy 13-year-old boy with allergic rhinitis and buckwheat allergy who presented with his first generalized tonicclonic seizure. Following admission, he developed dyspnea and tachypnea (respiratory rate of 38/min); on hospital day 2, oxygen desaturation (SaO 2 88%) accompanied by hemoptysis. Laboratory tests showed no evidence of coagulopathy or autoimmune disease. Chest radiography and computed tomography revealed bilateral pulmonary infiltrates consistent with alveolar hemorrhage.Intravenous methylprednisolone (1 mg/kg for 3 days) was administered, resulting in rapid improvement of respiratory symptoms and imaging findings. This case highlights the importance of early clinical suspicion and imaging-based diagnosis of post-ictal DAH, and the necessity of prompt supportive management to achieve favorable outcomes.

Primary antibody deficiency (PAD) is the most common form of primary immunodeficiency (PID) in adults, although the overall prevalence remains low. Recent studies have suggested a rising incidence due to changes in environmental factors and increased awareness. PID typically presents with recurrent upper and lower respiratory tract infections but may also be associated with allergic and autoimmune diseases, resulting in various clinical manifestations. This report presents three representative adult cases of PAD— X-linked agammaglobulinemia (XLA), common variable immunodeficiency (CVID), and IgG3 subclass deficiency (IgG3D) with bronchial asthma—offering insights into their diagnosis and long-term management. These cases emphasize the need to suspect XLA in patients with recurrent pneumonia and bronchiectasis, to recognize chronic severe urticaria as a potential clinical clue for CVID, and to evaluate IgG3D in asthma patients with frequent viral infections despite standard care. Through these examples, this clinical insight underscores the importance of early suspicion of PID, comprehensive immunological evaluation and individualized treatment strategies in improving outcomes for adult PID patients.

Purpose: This study aimed to evaluate the feasibility, safety, and immunological outcomes of low-dose cow’s milk oral immunotherapy (CM OIT) in school-aged children and adolescents with severe, persistent cow’s milk allergy (CMA), a group typically considered at a high risk for OIT. Methods: We conducted a retrospective study involving 12 patients (median age, 11.4 years) with immunoglobulin E (IgE)-mediated CMA, who underwent individualized low-dose CM OIT in the outpatient setting at a single tertiary hospital. Baseline and longitudinal clinical and immunological data, including casein-specific IgE and immunoglobulin G4 (IgG4) levels, were analyzed. Patients were classified as either desensitized or unsuccessful based on treatment outcomes. Results: Of the 12 patients with severe CMA, 6 achieved desensitization up to the target dose, while the remaining 6 discontinued treatment because of intolerance or poor adherence. The desensitized and unsuccessful groups showed no significant differences in baseline age, OIT starting dose, or serum casein-specific IgE level. Immunological evaluation revealed a significantly greater increase in serum casein-specific IgG4 (0.87 vs. -0.37 mg/L, P = 0.004) and a significantly lower natural log-transformed fold change in the IgE/IgG4 ratio (-1.38 vs. 0.44, P = 0.008) in the desensitized group. None of the patients required epinephrine during OIT, and adverse events were generally mild. Conclusion In selected high-risk pediatric populations with severe CMA, outpatient-based low-dose OIT using individualized flexible protocols may provide a relatively safe approach that improves tolerability and adherence. Increased casein-specific IgG4 levels and a reduced casein-specific IgE/IgG4 ratio may serve as valuable biomarkers for treatment response.

Background: The Act on Decisions on Life-Sustaining Treatment (LST) has been implemented in Korea since 2018, yet data on its application in neurocritical care units remain scarce. This study aimed to evaluate the clinical characteristics and outcomes of LST withdrawal or withholding in the neurocritical care unit. Methods: This study was a retrospective analysis conducted at a tertiary university hospital in Busan, South Korea. Among patients admitted to the neurocritical care unit between February 2018 and August 2023, those with documented decisions for LST withdrawal or withholding were enrolled. Demographic and clinical characteristics, underlying and combined conditions, reasons for LST decisions, measures taken, and time from LST withdrawal to death were extracted from medical records. Results: A total of 69 patients were included, with a median age of 67 years, and 38 (55%) were male. Cerebrovascular disease (62%) and traumatic brain injury (22%) were the most common underlying diagnoses. The primary reason for LST decisions was irreversible neurological damage (71%), followed by systemic complications (19%). Mechanical ventilation cessation (91%) and extubation (86%) were most frequently used measures for LST withdrawal. The median time from LST withdrawal to death was 22 minutes. Conclusions Our study demonstrates that LST decisions in the neurocritical care unit predominantly occur among patients with cerebrovascular disease or traumatic brain injury, mostly triggered by neurological deterioration. Most patients died shortly after withdrawal. These findings provide important insight into current LST withdrawal practices in neurocritical care and may assist clinical and ethical decision making in similar settings.
