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.

Chinese Medical Sciences Journal 2025;40(3):197-202
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.

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.
OBJECTIVETo 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.
METHODSThe 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.
RESULTSThe 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.
CONCLUSIONThe 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.

Philippine Journal of Urology 2025;35(2):121-126
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.
RESULTSAcross 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.
DISCUSSIONFindings 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.
CONCLUSIONThe 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.

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.

Acta Medica Philippina 2025;60(2):73-83
BACKGROUND AND OBJECTIVES
Natural disasters occur frequently in Indonesia, so the community must understand the impact of these disasters. Nurses, on the other hand, can perform trauma prevention care and carry out interventions in areas prone to natural disasters. The concept of trauma prevention care is not new in nursing. However, it needs to be analyzed further because there are still unclear definitions and inconsistencies in its implementation.
This study aims to describe the concept of trauma prevention care using the Walker & Avant analysis method.
METHODSThe Walker and Avant concept analysis method was used which consists of eight systematic steps. Information sources include electronic databases such as ScienceDirect, PubMed, EBSCO, and SAGE, for articles published from January 2006 to June 2024. Embase was searched for the terms "trauma prevention," AND "trauma prevention care," AND "trauma prevention natural disasters."
RESULTSThe literature search identified 80 articles in the fields of medicine, nursing, sociology, and psychology. After analysis, 13 articles were selected for this study. Data extraction and analysis adhered to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. Trauma prevention care is defined as 1) knowledge, 2) recognition, 3) caring, 4) respect, and 5) communication. The idea of antecedents includes trauma, education, and skills, while consequences comprise assessment, safety, resources, psychological stress, unidentified trauma, and limitations of nurses.
CONCLUSIONUnderstanding the attributes of trauma prevention care, along with its antecedents and consequences, can facilitate development in nursing practice. This concept of trauma prevention care can be used to conduct trauma assessment and prevention in natural disaster-prone areas to minimize the impact that will occur.

Southern Philippines Medical Center Journal of Health Care Services 2024;10(1):1-
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.
