OBJECTIVES

his quantitative cross-sectional study aimed to determine the level of knowledge, attitude, and practices
regarding COVID-19 vaccination of unvaccinated adult patients admitted at Region II Trauma and Medical Center
(R2TMC). This may help determine the knowledge gap regarding COVID-19 vaccination, address it, and to achieve
the goal to vaccinate all eligible Filipinos. Furthermore, this may also be a springboard for future researches and
management regarding novel infections needing new vaccinations.

METHODS

Collected data from the sample size of 197 using the formula for finite population with 95% confidence
level, population proportion of 50%, population size of 400, allowing 5% margin of error were summarized in a
Microsoft excel database and tables, then were analyzed using Jamovi version 2.6.22 software. Frequency, mean,
and standard deviation were calculated to measure the knowledge, attitude, and practices; Pearson correlation and
Kendall’s Tau b correlation for its relationship.

RESULTS

There is moderate level of knowledge (MS: 9.80-11.8), a positive attitude (MR: 2.35-2.60), and good preventive
practices (MS: 12.00-13.00) regarding SARS-CoV-2 (COVID-19) vaccination among the unvaccinated adult in-patients
of R2TMC post-pandemic. Knowledge, attitudes, and practices statistically differed (pCONCLUSION

There is a significant correlation among the knowledge of the respondents about COVID-19 vaccination,
their attitude towards it, and their practices, implying that promoting preventive behaviors toward COVID-19 would
require promoting both knowledge and efficacy beliefs among the public.

Diffuse infiltrating retinoblastoma is an extremely rare form of retinoblastoma which is characterized by its atypical growth pattern. This unusual presentation adds complexity to the diagnostic process. The purpose of this paper is to report a rare presentation of diffuse infiltrating retinoblastoma presenting after an ocular trauma. We described a 7-year-old Filipino boy presenting with total hyphema following an ocular trauma. Comprehensive ophthalmologic clinical and diagnostic evaluations were performed including visual acuity, slitlamp biomicroscopy, ocular ultrasound, neuroimaging, and histopathology post enucleation to determine diagnosis. The misleading, atypical presentation of diffuse infiltrating retinoblastoma may delay diagnosis. While this dilemma is expected in these scenarios, it should be remembered that timing of diagnosis in retinoblastoma is crucial, as this also equates to optimal management. One should remain vigilant for these uncommon presentations especially in the setting of any intraocular inflammation in children.

INTRODUCTION

Diffuse cutaneous mastocytosis (DCM) is a rare and severe form of cutaneous mastocytosis which may present in the neonatal period; thus early recognition is essential. Symptoms of mastocytosis are exacerbated by mast cell degranulating agents more commonly from heat, friction, local trauma, drugs and food. This is a case of DCM presenting with bullous eruptions after immunization.

CASE REPORT

An 11-month-old boy presented with generalized erythematous to hyperpigmented macules and patches initially at birth, with progression to bullous eruptions immediately after immunization without any systemic symptoms. Biopsy revealed superficial and deep mixed cell infiltrates consisting of lymphocytes, histiocytes and numerous mast cells. Giemsa stain highlighted the metachromatic mast cell granules. Serum tryptase was elevated by 13 times (130 ug/L). The patient was prescribed oral antihistamines and topical steroids that offered good response. Avoidance of all potential triggers was instructed.

DISCUSSION

The extensive cutaneous involvement in DCM (generalized erythema, diffuse papules that develop pachyderma, darker skin, peau d’orange) are due to the diffuse infiltration of the dermis with mast cells, accompanied with an elevated serum tryptase.

Unique to this local case are exacerbations triggered by vaccination. There is literature to support evidence of vaccination reactions to pentavalent vaccine in children with DCM though the pathway associated with mast cell degranulation after immunization has not yet been specified.

It is advised that patients with DCM follow scheduled immunization guidelines with precautionary measures.

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.

METHODS

The 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."

RESULTS

The 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.

CONCLUSION

Understanding 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.

BACKGROUND

Burn injuries remain a significant global public health problem, causing substantial morbidity, mortality, and economic burden, particularly in low- and middle-income countries where nearly 90% of cases occur. Despite the importance of timely and appropriate first aid in reducing complications, community responses to burn injuries in many settings continue to rely on traditional or non-evidence-based practices.

OBJECTIVES

This qualitative phenomenological study explored community-based knowledge and responses related to the causes and first aid of burn injuries.

METHODS

The study involved ten (10) purposively selected informants residing in South Mangga Dua Urban Village, Central Jakarta, Indonesia. Data collection methods included semi-structured interviews, direct observations, and focus group discussions (FGDs). Thematic analysis was used.

RESULTS

Three (3) core domains were identified: (1) community perceptions of burn causes and classifications, (2) indigenous first aid practices used in domestic settings, and (3) sources of knowledge and information pathways related to burn first aid. Participants commonly attributed burns to incidents involving fire, hot liquids, and electrical faults. Their understanding of burn severity was limited to superficial assessments, with little awareness of clinical classifications. First aid responses were largely based on traditional practices such as the application of toothpaste, honey, or aloe vera, while evidencebased practices like using running water were rarely mentioned. Notably, most participants relied on familial teachings and informal community experiences as their primary sources of knowledge, with limited exposure to health professionals or verified media content.

CONCLUSION

Community knowledge is culturally rooted but misaligned with medical standards, potentially leading to unsafe practices. Culturally sensitive health education integrating traditional beliefs and accurate information is essential to improve outcomes in burn injury management.

BACKGROUND

Penetrating brain injury (PBI) is a leading cause of combat mortality but local outcome data is limited. The authors examined combat-related PBI cases to describe patient characteristics and identify clinical and radiologic predictors of functional recovery

METHODS

This is a retrospective cohort study of military personnel aged 18–56 years with combat-related PBI referred to VLGH AFPMC between January 2017 to June 2022. The authors collected demographics data, injury mechanism, pre-hospital and transfer details, admission clinical and radiologic findings, treatments, and follow-up outcomes. The Glasgow Outcome Scale (GOS), dichotomized into unfavorable (GOS 1–3) and favorable (GOS 4–5), was used to assess functional status. Associations were tested with Fisher’s Exact Test.

RESULTS

Thirty-seven patients met inclusion criteria: 31 survivors with follow-up and 6 who died in hospital. All were male; gunshot wounds accounted for 81% of injuries. At a median follow-up of 27 months, among survivors, 74% had a Glasgow Coma Scale (GCS) of 15 and 45% achieved good recovery (GOS 5). Pre-hospital timing measures (evacuation time, interval to surgery, and transfer delays) were not significantly associated with outcome. Favorable outcomes correlated strongly with higher admission GCS (p < 0.001), preserved baseline motor function (p < 0.001), smaller hemorrhage volume (p = 0.01), and injury limited to a single lobe (p < 0.001). Unfavorable outcomes were associated with intracranial infection, post-traumatic seizures, and need for multiple surgeries (all p < 0.001).

CONCLUSION

Functional recovery after combat-related PBI in this cohort was principally determined by initial neurologic status, injury extent, and subsequent complications The lack of association with pre-hospital timing possibly reflects survivorship bias and incomplete capture of early fatalities.

Chronic non-healing wounds significantly impair patient rehabilitation and remain a critical clinical challenge. Stem cell-derived exosomes, owing to their biocompatibility and physiological activity, have emerged as a promising therapeutic approach in regenerative medicine. Beyond their intrinsic wound-healing properties, exosomes are increasingly explored as carriers for small-molecule drugs to enhance synergistic treatment effects. Although microRNAs (miRNAs) exhibit potential in promoting cell proliferation and re-epithelialization, their clinical application is hindered by poor stability. In this study, we investigated the therapeutic effects of miR-132-3p-loaded human umbilical mesenchymal stem cell-derived exosomes (miR-132-3p@UMSC-EXOs) on human foreskin fibroblast-1 (HFF-1). Our findings demonstrated that miR-132-3p@UMSC-EXOs significantly enhanced proliferation and migration of HFF-1, while reducing intracellular reactive oxygen species (ROS) levels compared with unloaded exosomes. Furthermore, qRT-PCR and Western blotting analyses revealed that miR-132-3p@UMSC-EXOs modulated the expression of genes associated with extracellular matrix (ECM) remodeling and inflammation, suggesting their potential to upregulate collagen synthesis and improve ECM metabolism. These results highlight the therapeutic promise of miR-132-3p@UMSC-EXOs in accelerating wound healing.

Objective To evaluate the efficacy and safety of systemic thrombolysis(ST)and standard anticoagulation(SA)in the treatment of lower extremity fracture complicated with distal deep vein thrombosis(DDVT).Methods We retrospectively analyzed the clinical data of 60 patients with lower extremity fracture complicated with DDVT treated from January 2021 to December 2023.When the lower limb venography indicated a calf thrombus burden score ≥3 points,a retrievable inferior vena cava filter(IVCF)was successfully placed in the healthy femoral vein before orthopedic surgery.The patients who received further anticoagulant or thrombolytic therapy after surgery were allocated into a ST group(n=30,urokinase ST and SA)and a SA group(n=30,only SA).The two groups were compared in terms of calf thrombus burden score,thrombus dissolution rate,IVCF placement time,IVCF retrieval rate,intercepted thrombi,hemoglobin level,platelet count,D-dimer level,and complications.Results There was no statistically significant difference in the calf thrombus burden score between the two groups before treatment(P=0.431).However,after treatment,the scores in both groups decreased(both P<0.001),with the ST group showing lower score than the SA group(P=0.002).The thrombus dissolution rate in the ST group was higher than that in the SA group(P<0.001).There was no statistically significant difference in the IVCF placement time between the two groups(P=0.359),and the IVCF retrieval rate was 100% in both groups.The ST group had fewer intercepted thrombi than the SA group(P=0.002).There was no statistically significant difference in hemoglobin level(P=0.238),platelet count(P=0.914),or D-dimer level(P=0.756)between the two groups before treatment.However,after treatment,both groups showed an increase in platelet count(both P<0.001)and a decrease in D-dimer level(both P<0.001).There was no statistically significant difference in the occurrence of complications between the two groups(P=0.704).Conclusions Both SA and ST demonstrate safety and efficacy in the treatment of lower extremity fractures complicated with DDVT,serving as valuable options for clinical application.Compared with SA,ST not only enhances the thrombus dissolution in the calf but also mitigates the risk of thrombosis associated with IVCF.

OBJECTIVE: To investigate the effects of low-dose irradiated autologous peripheral blood reinfusion (LDIAPBR) on a rat model of radiation-induced leukopenia. METHODS: The rats were randomly divided into four groups. In the LDIAPBR group, LDIAPBR was performed 1 day before modeling (10% of the total circulating blood volume was withdrawn, irradiated with 100 mGy ex vivo, and completely reinfused). Meanwhile, the normal group and model group only underwent blood withdrawal and reinfusion of the same proportion without blood irradiation. Except for the normal group, all groups were subjected to 1 Gy X-ray whole-body irradiation to establish a radiation-induced leukopenia rat model. The positive drug group received subcutaneous injection of rhG-CSF after modeling. It was monitored that the general condition of the rats, peripheral blood cell counts, immune organ indices, bone marrow nucleated cell counts and viability, and the pathological analysis of bone marrow sections was conducted. RESULTS: The LDIAPBR group exhibited significant improvements in overall condition compared to the model group. Notably, compared with the model group, peripheral blood leukocyte and lymphocyte counts were markedly higher in the LDIAPBR group. Furthermore, there was a significant increase in both the number and viability of nucleated cells in the bone marrow. Pathological examination of bone marrow sections revealed increased nucleated cell density and reduced cavity area in the LDIAPBR group. CONCLUSION LDIAPBR can effectively improve hematological parameters and bone marrow hematopoietic function in a rat model of radiation-induced leukopenia, providing a new approach for the prevention and treatment of radiation-related injuries.

OBJECTIVE: To observe the dynamic changes of microvascular injury and repair in the penumbra of traumatic brain injury (TBI) rats with effective cerebral perfusion microvascular imaging using optical coherence tomography angiography (OCTA). METHODS: Transparent closed cranial windows were placed in craniotomy rats after TBI caused by weight drop. All the rats in TBI group and control group underwent head MRI examination on the first postoperative day, and the changes of cerebral cortical microvessel density were measured by OCTA through cranial windows on d0, d2, d4, d6, and d8. On the second day after the operation, the same number of rats in the two groups were selected to complete the immunohistochemical staining of brain tissue with pimonidazole, an indicator of hypoxia. RESULTS: MRI T2W1 and immunohistochemical staining demonstrated that edema and hypoxia in the traumatic brain tissue extended deeply throughout the entire cortex. OCTA showed that the cortical surface veins of the rats in both groups were significantly dilated and tortuous after operation, and recovered to the postoperative day level on d8. The effective perfusion microvessel density of the rats in both groups gradually recovered after a temporary decrease, and the TBI group decreased from 39.38%±4.48% on d0 to 27.84%±6.01% on d2, which was significantly lower than that on d0, d6, and d8 (P < 0.05). The highest value was 61.71%±7.69% on d8, which was significantly higher than that on d0, d2, and d4 (P < 0.05). The control group decreased from 44.59%±7.78% on d0 to 36.69%±5.49% on d2, which was significantly lower than that on d0, d6, and d8 (P < 0.05). The highest value was 51.92%±5.96% on d8, which was significantly higher than that on d2, and d4 (P < 0.05). Comparing the two groups, the effective perfusion microvessel density in the TBI group was significantly lower than that in the control group on d2 (P=0.021), and significantly higher than that in the control group on d8 (P=0.030). CONCLUSION OCTA can be used as a method of imaging and measurement of effective perfusion microvessels in the injured cerebral cortex of TBI rats. After TBI, the effective perfusion microvessel density in the wound penumbra gradually recovered after decreasing, and increased significantly on d8.
