The use of immersive technologies in learning about postpartum hemorrhage: Protocol for a systematic review and meta-analysis Montiel-Bravo, María-José; Ferrandini-Price, Mariana; Pardo-Ríos, Manuel; Sánchez-Gómez, Marina; Piuvezam, Grasiela; Silva-de-Medeiros, Gidyenne-Christine-Bandeira; López-López, Carmen-Amalia Postpartum hemorrhage is one of the leading causes of maternal morbidity and mortality worldwide, and its proper management requires both technical and non-technical skills. This study describes the protocol for a systematic review evaluating the effectiveness of immersive technologies in training healthcare professionals in the management of this obstetric emergency. This protocol was registered in the International Prospective Register of Systematic Reviews (PROSPERO) database (CRD420250614446). The search will be performed in the following databases: PubMed, Embase, Scopus, ScienceDirect, Web of Science, Cochrane Library, LILACS, Enfispo and CUIDEN. Intervention studies (clinical trials - randomized or non-randomized) and quasi-experimental studies will be included. The risk of bias will be assessed using appropriate tools according to study design: the Risk of Bias 2 (ROB 2) tool for randomized controlled trials and the Risk Of Bias In Non-randomized Studies of Interventions (ROBINS-I) tool for non-randomized and quasi-experimental studies. Two independent researchers will conduct all assessments, and any disagreements will be consulted with a third reviewer. The data analysis and synthesis will be performed using Review Manager software version 5.4. We will conduct the study in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols (PRISMA-P) guidelines. The review will summarize the current evidence on the use of virtual reality, augmented reality, and mixed reality in education and training for postpartum hemorrhage management. The planned systematic review will identify and synthesize the available evidence on how immersive technologies may improve learning about postpartum hemorrhage.

Aprendizaje combinado frente a realidad virtual y métodos tradicionales en la formación en reanimación cardiopulmonar: un ensayo aleatorizado en estudiantes universitarios Ocampo-Cervantes, Ana-Belén; Greif, Robert; Castro-Delgado, Rafael; López-López, Carmen-Amalia; Carrión-García, Eduardo; Pardo-Ríos, Manuel OBJECTIVE: Out-of-hospital cardiac arrest is the leading cause of sudden death. Basic Life Support (BLS) training is an essential competency in Nursing. Active learning methodologies such as blended learning may improve educational outcomes. DESIGN: A randomized controlled trial with four parallel groups (n=160). PARTICIPANTS: was conducted among first-year undergraduate nursing students. Site: At a university in the Region of Murcia, Spain. INTERVENTIONS: Four methodologies were compared: traditional training, virtual reality (VR), blended learning, and a control group with no intervention. Practical competence was assessed using an 8-item checklist covering key steps in the chain of survival. Technical parameters were measured using Laerdal QCPR® manikins, including percentage of high-quality CPR, compression depth, rate, and full chest recoil. ANOVA, chi-square tests, and correlation models were applied (p<0.05). RESULTS: Practical competence differed significantly between groups (p<0.001). MAIN MEASUREMENTS: The blended and traditional groups achieved the highest scores (6.6±1.7 and 6.6±1.5, respectively), followed by the VR group (6.3±1.5) and the control group (3.1±1.5). Mean CPR quality also differed significantly (p=0.0045), with the blended group showing the highest percentage (72.3%), followed by traditional (65.4%), VR (63.4%), and control (46.9%). Regarding compression depth (p=0.0011), the blended and VR groups achieved similar results (6.1cm), outperforming the traditional (5.5cm) and control (4.8cm) groups. Perceived usability of the VR system was high (78/100). CONCLUSIONS: Blended learning showed overall better performance in most variables analyzed, with higher CPR quality and equal or superior results in practical competence and compression depth compared to the traditional and immersive models. These findings support its effectiveness as a teaching strategy for acquiring BLS competencies.

Dimethyl fumarate induced Wells syndrome. A case report

Dimethyl fumarate induced Wells syndrome. A case report Candeliere-Merlicco, Antonio; Villaverde-González, Ramón; Hidalgo-Pérez, Paloma-Victoria; Escobar-Arias, Fabio-Hugo; Aparicio-Castro, Eladio; Lastres-Arias, María-del-Carmen INTRODUCTION: Wells syndrome, also known as eosinophilic cellulitis, is a rare dermatosis with approximately 200 cases previously described in the literature. Here, we present a case of a patient with multiple sclerosis with Wells syndrome induced by dimethyl fumarate (DMF). CASE REPORT: A 41-year-old Caucasian woman was treated with DMF in July 2021. One week later, she experienced itching on her upper and lower right arm, followed by the appearance of erythematous plaques covered with vesicles. The complete blood count showed an increased eosinophil count of up to 2,000 µL. The histological images demonstrated dermal eosinophil infiltration concordant with Wells syndrome. The clinical course was benign, with complete resolution of the lesions and normalization of the eosinophil count within four weeks. Administration of corticosteroids was not necessary. CONCLUSIONS: Eosinophilia is rare in patients with multiple sclerosis treated with DMF and usually does not require dosage adjustments. Although clinical manifestations of eosinophilia in these patients are very rare, it is important for practitioners to recognize the symptoms. Many neuroleptic drugs can induce eosinophilia and systemic symptoms; therefore, physicians must be aware of the risks associated with DMF and neuroleptic drugs, particularly for quetiapine, which contains fumarate.

Evaluation of advanced life support training through virtual reality: A cross-sectional observational study in a hypothermia and helicopter evacuation scenario

Evaluation of advanced life support training through virtual reality: A cross-sectional observational study in a hypothermia and helicopter evacuation scenario Sánchez-Gómez, Marina; López-López, Carmen-Amalia; Greif, Robert; Semeraro, Federico; Ocampo-Cervantes, Ana-Belén; Pons-Claramonte, Manuel; Nieto-Caballero, Sergio; Alcázar-Artero, Petronila-Mireia; Pardo-Ríos, Manuel; Guillén-Martínez, Daniel To evaluate clinical performance and user perception after advanced life support training through immersive virtual reality (VR) simulation, focused on decision-making in a hypothermia scenario involving a helicopter evacuation. Cross-sectional observational study with an analytical component. Update Course on Ultrasound and Emergencies organized by the semFYC, held in Las Palmas de Gran Canaria from February 6 to 8, 2025. 101 healthcare professionals who fully completed the simulation experience and assessment questionnaires. Immersive VR clinical simulation using a 360 degrees video recorded at a ski station, presented through Meta Quest 3 (R) headsets. The scenario included 16 clinical decisions related to the management of a hypothermic patient during air transport. Percentage of correct clinical decisions, subjective perception (satisfaction, realism, confidence), and system usability assessed using the System Usability Scale (SUS). The mean score for correct decisions was 69.4% (SD = 15.2). Participants rated the experience very positively, highlighting realism (8.87/10), training usefulness (M > 4.7/5), and increased clinical confidence. The mean SUS score was 76.7, indicating "good" usability. A lower performance was identified in specific advanced hypothermia decision-making items. Immersive VR simulation proved to be a feasible, well-accepted, and useful strategy for training in clinical decision-making in complex, low-frequency scenarios. The results support its integration as a complementary tool in continuing emergency training programs.
