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.

Fangcang shelter hospitals are modular, rapidly deployable facilities that play a vital role in pandemic response by providing centralized isolation and basic medical care for large patient populations. Artificial intelligence (AI) has the potential to transform Fangcang shelter hospitals into intelligent, responsive systems that are capable of significantly improving emergency preparedness, operational efficiency, and patient outcomes. Key application areas include site selection and design optimization, clinical decision support, AI-assisted clinical documentation and patient engagement, intelligent robotics, and operational management. However, realizing AI's full potential requires overcoming several challenges, including limited data accessibility, privacy and governance concerns, inadequate algorithmic adaptability in dynamic emergency settings, insufficient transparency and accountability in AI-driven decisions, fragmented system architectures due to proprietary formats, high costs disproportionate to the temporary nature of Fangcang shelter hospitals, and hardware reliability in austere environments. Addressing these challenges demands standardized data-sharing frameworks, development of explainable and robust AI algorithms, clear ethical and legal oversight, interoperable modular system designs, and active collaboration among multidisciplinary stakeholders.

OBJECTIVE: To explore the feasibility of establishing a temporary trauma team led by trauma experts in primary hospitals for disaster medical rescue. METHODS: In the coal mine flooding accident in Xiaoyi City, Shanxi Province on December 15, 2021, according to the local emergency plan and the characteristics of the accident, the trauma experts trained the medical staff from the local primary hospital on advanced trauma life support (ATLS) and damage control surgery (DCS) in the short time interval between the occurrence of the mine disaster and the admission of medical staff to the disaster scene. A temporary trauma team composed of trauma experts, ATLS team, and DCS team was formed to provide early diagnosis and treatment for survivors before and in the hospital. RESULTS: The miners were found on the 36th hour of the disaster. All 22 miners were male, and 2 died underground. Another 20 people were rescued 39－43 hours after the disaster, with a median age of 48 years (34-57 years). All the survivors suffered from hypothermia, dehydration, maceration of feet and other injuries. There were 18 cases of acute inhalation tracheobronchitis, 14 cases of electrolyte acid-base disturbance, 6 cases of trunk contusion, 1 case of psoas major hematoma, and 1 case of lower extremity hematoma. Deep vein thrombosis was in 4 cases. The ATLS team focused on injury assessment, rewarming and rehydration within 50－60 minutes before admission, and completed auxiliary examinations within 2 hours after admission to clarify the diagnosis. The DCS team evaluated 6 patients with mechanical blunt trunk injury and excluded the indication of emergency surgery. The trauma experts conducted the whole process of supervision and quality control of disaster rescue. The positive rate of capillary refill test in the all survivors at the third hour of admission was significantly lower than that immediately after being rescued (75.0% vs. 15.0%, P=0.000 3), and they were discharged 4－7 days after admission. CONCLUSION Under the leadership of trauma experts and relying on the medical staff of primary hospitals, it is feasible to establish and train a temporary trauma team with ATLS and DCS functions to participate in the medical rescue of disasters, which is in line with the current national conditions of China.

Wunderlich Syndrome is a rare potentially life-threatening phenomenon that involves spontaneous non-traumatic retroperitoneal hemorrhage. At present, identifying the course of conservative management in these patients, especially in pregnancy, has not been clinically established. Presented here is a known case of Tuberous Sclerosis Complex with a Bilateral, 10cm Angiomyolipoma in a 31-year-old female, initially managed with active surveillance. At 27 weeks of pregnancy, she presented with a sudden onset of left flank pain with a hematocrit of 22%. Anemia was corrected with blood transfusions. A contrast-enhanced MRI of the abdomen showed a large subcapsular perirenal hematoma of the left kidney. Renal angioembolization of the bleeding segmental renal artery was done. The patient was conservatized until 37 weeks of pregnancy and underwent cesarean section delivery.

Four months after angioembolization, she had a recurrence of the left flank pain associated with gross hematuria and hypovolemic shock. The patient underwent emergency renal exploration of the left kidney via a transabdominal approach. Three liters of hemoperitoneum and a large expanding left retroperitoneal hematoma were noted intraoperatively. Early vascular control before nephrectomy of the left kidney was done. The postoperative course was unremarkable and the patient was discharged with improved condition.

This case displays a unique course in the management of a bleeding angiomyolipoma especially during pregnancy. Renal angioembolization can aid in achieving the age of viability in pregnancy. However, close monitoring for rebleeding should be kept in mind. A lower threshold for conservative management should be utilized when patients have a previous history of bleeding.

METHODOLOGY

A survey was conducted among 463 adults in Manila, achieving a valid response rate of 92.3% (427 responses analyzed). Participants represented diverse socioeconomic backgrounds. The survey explored perceptions regarding AAA of healthcare services for neurological emergencies.

RESULTS

Across income levels (poor, middle, rich), participants favored private hospitals for accessibility and convenience, such as emergency room access and prompt care. Private hospitals were also preferred for availability of diagnostic equipment, medications, specialist expertise and 24/7 care. Public hospitals, however, were preferred for affordability, particularly for emergency visits, medications, tests, neurologist consultations and ambulance services.

DISCUSSION

Findings reveal a clear preference split: private hospitals are valued for accessibility and resources, while public hospitals remain the affordable choice. This reflects ongoing systemic and socioeconomic challenges in Manila’s healthcare landscape.

CONCLUSION

The study provides actionable insights for policymakers and healthcare providers seeking to improve emergency neurological care. Addressing gaps in access and affordability can enhance patient outcomes and satisfaction while promoting more equitable healthcare delivery.

BACKGROUND

The Philippines faces a challenge in addressing the mental health needs of internally displaced persons (IDPs) following disasters. The lack of an integrated mental health triage system within evacuation centers and the shortage of specialists trained in post-traumatic stress triaging have hindered effective emergency response. Existing interventions primarily focus on traditional trauma and psychiatric symptoms, often lacking standardized mental health triage classifications and leading to data gaps, complicating resource allocation decisions.

OBJECTIVE

To develop a culturally relevant mental health triage system, this study proposes the "Unahon Tool" to meet the needs of Filipino IDPs. Integrating with existing medical triage protocols equips frontline responders to identify stress-related concerns, enables informed decision-making for mental health and psychosocial support (MHPSS) allocation, and optimizes resource utilization.

METHODS

The study involved key informants, including disaster responders, mental health specialists, and government officials, who participated in interviews and focus group discussions. Thematic analysis was used to identify behavioral aspects affecting IDP communities. The Unahon Tool development incorporated disaster response frameworks, mental health interventions, and other existing triage tools. A red-yellow-green categorization system was employed based on the severity and urgency of observed behaviors. Stakeholder consultations and expert reviews guided tool refinement.

RESULTS

The final Unahon Tool includes 17 behaviors categorized into red (urgent), yellow (moderate), and green (low) severity levels. It provides corresponding recommended interventions to aid responders. During direct observations, yellow-category behaviors like shouting and cursing were prevalent. Responders focused on reminders for peace and order in response to these behaviors. The tool's "Notes" section was identified as a potential area for contextual information inclusion.

CONCLUSION

The Unahon Tool fills a crucial gap in the Philippine disaster response infrastructure by offering a behavior-based mental health triage system. It enables responders to prioritize mental health resources effectively, reducing the burden on specialists and enhancing overall disaster response effectiveness. Future directions   include expanding tool adoption beyond Metro Manila, translating it into regional languages, and developing a version for children and teenagers. Collaboration with other regions and age groups will ensure broader applicability and effectiveness in addressing mental health needs among diverse IDP populations.

INTRODUCTION: Cancer patients attending emergency departments (EDs) often present with acute symptoms and are frequently admitted. This study aimed to characterise the profile of oncology patients who were discharged from the ED. METHODS: This was a retrospective audit of patients with cancer-related diagnoses who presented to the ED at the Singapore General Hospital (SGH) over a 6-month period from 1 October 2018 to 31 March 2019 and were directly discharged from the ED. Data was extracted from the hospital's electronic medical record system. RESULTS: Of the 492 participants included in the study, the majority were triaged as Priority 2 (61.4%), while 30.7% were triaged as Priority 3, 6.9% as Priority 1 and 1.0% as Priority 4. There was no statistical difference between the National Early Warning scores across the different triage categories in these patients. The most common complaint was (44.3%), followed by genitourinary symptoms (19.5%) and those related to devices, catheters or stomas (17.3%). More investigations of all types were done for patients being managed in Priority 1 (57.6%) than in the other triage categories (40.1% for Priority 2, 23.2% for Priority 3 and 12.0% for Priority 4). Treatment procedures carried out were mainly symptomatic (analgesics, antiemetics, proton pump inhibitors) for 79.8% of the patients. There were no significant differences in the proportion of patients requiring various treatment modalities among the triage categories. CONCLUSION Selected oncological patients may potentially be managed in an ambulatory setting.

On July 4, 2021, a Philippine C-130 military plane carrying 104 personnel crashed in Patikul, Sulu after attempting to land at Jolo Airport, killing 53 individuals and injuring 50 others, both on board and on the ground. Some of the injured sustained multiple injuries, including fractures and burns. This incident triggered a swift response from various agencies. Mass casualty incidents, including those with multiple burn-injured patients, pose significant challenges to health care systems and can lead to high morbidity and mortality rates.1 2 3 Burn injuries, which account for at least 200,000 deaths annually, are a major global public health issue, particularly in low-resource settings, and can easily overwhelm the limited burn resources available.4 5 6 Efficient management of mass casualty incidents, proper triage decisions, and sound health care planning are crucial for optimizing patient outcomes and matching potential needs with available resources.7 Burn mass casualty incidents (BMCI) are incidents that involve at least three burn victims. These incidents, whether due to natural or human-caused accidents, can occur anywhere and anytime. The injuries are unpredictable and involve a large number of victims, requiring a significant consumption of logistics and medical attention. Medical response tasks in massive burn injuries are much more challenging than those required in separate burn incidents due to the unexpected nature of the events and the simultaneous involvement of a large number of patients. Such situations require the immediate mobilization of a significant number of personnel, resources, and facilities to address upcoming issues. In this article, we describe the management of BMCIs based on our experiences in responding to the Patikul incident. We elucidate the strategies that are put into action and offer insights aimed at improving protocols for handling BMCIs in the future. Our goal is to contribute to the body of knowledge in this field and aid in the development of more effective responses to such critical situations.

A burn mass casualty incident (BMCI), an incident that involves at least three burn victims with severe injuries,1 presents several unique challenges. In a mass casualty event, between 25 and 30 percent of those injured can sustain moderate-to-severe burn injuries.2 Management of burn patients necessitates a significant amount of health resources and logistical support, along with prompt and high-quality care to optimize the functional and cosmetic outcomes of severely injured patients. While some developed countries have sound disaster management plans, many countries where most BMCIs occur lack such well-established plans.3 The effective management of BMCIs is crucial for positive patient outcomes. Given resource scarcity, especially in geographically isolated and disadvantaged areas, comprehensive mitigation and preparedness strategies are essential. These strategies must address worst-case scenarios that may challenge the existing internal protocols, especially at the local level.4 The surge in health care facility capacity during BMCIs can quickly overwhelm local and regional resources, from prehospital care to specialized burn centers. In the Philippines, disaster response levels and adequacy may vary widely among different regions and local government units (LGU). While the Department of Health has issued guidelines for health emergency and disaster response management,5 there are currently no policies or guides on specifically addressing preincident planning for BMCIs. The aim of this article is to recommend policies that will potentially improve the current health care approach to BMCIs.

INTRODUCTION: Emergency laparotomy (EL) is associated with high morbidity and mortality, often exceeding 10%. This study evaluated the impact of the EMergency Laparotomy Audit (EMLA) interdisciplinary perioperative pathway on patient outcomes, hospital costs and length of stay (LOS) within a single centre. METHOD: A prospective cohort study was conducted from August 2020 to July 2023. The intervention team included specialist clinicians, hospital administrators and an in-hospital quality improvement team. Patients who underwent EL were divided into a pre-intervention control group (n=136) and a post-intervention group (n=293), and an 8-item bundle was implemented. Propensity scoring with a 1:1 matching method was utilised to reduce confounding and selection bias. The primary outcomes examined were LOS, hospitalis-ation costs and surgical morbidity, while secondary outcomes included 30-day mortality and adherence to the intervention protocol. RESULTS: The utilisation of the EMLA perioperative care bundle led to a significant reduction in surgical complications (34.8% to 20.6%, P<0.01), a decrease in LOS by 3.3 days (15.4 to 12.1 days, P=0.03) and lower hospitalisation costs (SGD 40,160 to 30,948, P=0.04). Compliance with key interventions also showed improvement. However, there was no difference in 30-day mortality. CONCLUSION This study offers insights on how surgical units can implement systemic perioperative changes to improve outcomes for patients undergoing emergency laparotomy.
