ABSTRACT

INTRODUCTION: The use of YouTube® has spread among patients with chronic diseases such as multiple sclerosis (MS). These patients consult the available videos to learn more about their disease in terms of diagnosis and making decisions about treatments, including rehabilitation. The aim of this study was to evaluate the content, educational value, and quality analysis of MS videos about neurorehabilitation on YouTube® using quantitative instruments. MATERIALS AND METHODS: A search was conducted on YouTube®. The first 30 videos that met the inclusion criteria were reviewed. The videos were classified according to the upload source and the content. All videos included in the review were assessed by the DISCERN questionnaire, the JAMA benchmark, the global quality scale (GQS) and the video information and quality index (VIQI). RESULTS: The mean scores were: 28.3 (±9.33) in DISCERN, 2 (±0.81) in JAMA, 2.57 (±1.22) in GQS, and 11.73 (±4.06) in VIQI. JAMA score statistically significantly differed according to upload source (p = 0.002), video content (p = 0.023) and the speaker (p = 0.002). The DISCERN, JAMA, GQS, and VIQI scores showed significant correlations with each other. CONCLUSIONS: The analyzed videos about neurorehabilitation in people with MS on YouTube® were quite old since the upload, with a moderate duration and number of views, but with a poor quality of the content, educational value, and quality analysis of the videos. Our research showed that there were statistically significant differences in terms of quality, transparency, and reliability of the information, depending on the upload source, video content and the speaker.


TITLE: Análisis de contenido, valor educativo y calidad de los vídeos sobre neurorrehabilitación de la esclerosis múltiple en YouTube®.Introducción. El uso de YouTube® se ha extendido entre los pacientes con enfermedades crónicas como la esclerosis múltiple (EM). Estos pacientes tienden a consultar los vídeos disponibles para aprender más sobre su enfermedad, en términos de diagnóstico y toma de decisiones sobre tratamientos, incluida la rehabilitación. El objetivo de este estudio fue evaluar el contenido, el valor educativo y el análisis de la calidad de los vídeos sobre neurorrehabilitación de la EM en la plataforma YouTube®, empleando instrumentos cuantitativos validados. Materiales y métodos. Se realizó una búsqueda en la plataforma YouTube®. Se revisaron los 30 primeros vídeos que cumplían los criterios de inclusión establecidos. Los vídeos se clasificaron según la fuente de subida y el contenido. Todos los vídeos incluidos en la revisión se evaluaron mediante el cuestionario DISCERN, el índice de referencia JAMA, la escala de calidad global (GQS) y el índice de información y calidad de vídeo (VIQI). Resultados. Las puntuaciones medias fueron: 28,3 (±9,33) en DISCERN, 2 (±0,81) en JAMA, 2,57 (±1,22) en GQS y 11,73 (±4,06) en VIQI. La puntuación en la escala JAMA difirió de forma estadísticamente significativa según la fuente de carga (p = 0,002), el contenido del vídeo (p = 0,023) y el perfil de la persona que lo ejecutaba (p = 0,002). Las puntuaciones en DISCERN, JAMA, GQS y VIQI mostraron correlaciones significativas entre sí. Conclusiones. Los vídeos analizados sobre neurorrehabilitación en personas con EM y que aparecen en la plataforma YouTube® eran bastante antiguos desde su fecha de subida, con una duración y un número de visualizaciones moderados, y con una calidad deficiente en su contenido, en su valor educativo y en el propio análisis de los mismos. Nuestra investigación mostró que había diferencias estadísticamente significativas en términos de calidad, transparencia y fiabilidad de la información, dependiendo de la fuente de subida, el contenido del vídeo y el perfil de la persona que lo ejecutaba.

ABSTRACT

Anticoagulant rodenticides (ARs) are one of the most toxic groups of compounds currently used worldwide for rodent pest control. Toxic baits are often, directly or indirectly, ingested by non-target animals, resulting in secondary poisoning and frequently affecting apex predators. Their presence in many species of raptors is quite common, particularly scavenger species, with some of these acting as sentinels for the presence of these substances in the environment. However, there is less data on the presence of ARs in Bonelli's eagle, one of the most endangered eagle species in Spain and which is experiencing a negative population trend in Europe. This medium-sized eagle feeds predominantly on live species, and rarely consumes carrion. In this study, 17 carcasses of Bonelli's eagles from the Eastern Spain were necropsied. Both first and second generation ARs in their livers were analyzed by HPLC-MS-TOF revealing that all the eagles studied had been exposed to at least 5 ARs, out of a total of 10 ARs analyzed, with 7 being the highest number of ARs detected in a sample. Second generation ARs were the most prevalent, particularly bromadiolone and brodifacoum, with the highest concentrations in 94% of the cases. More than a third of the eagles presented a liver concentration of greater than 200 ng/g ARs, suggesting AR poisoning. The elevated presence of these compounds in Bonelli's eagles could be a new cause of mortality for this species or could explain other causes of death, such as the increased mortality in power lines, and should be taken into account for their conservation. At the same time, the presence of these compounds in the environment also represents a risk to public health, as the most frequent species in the diet of Bonelli's eagle (rabbits and partridges) are also hunted and consumed by hunters and their families.

ABSTRACT

BACKGROUND: Carbohydrate antigen 125 (CA125) is a proteolytic fragment of MUC-16 that is increased in heart failure (HF) and associated with inflammation, fluid overload, and worse adverse events. Our main objective was to study the expression of CA125 on epicardium and its association with inflammation, adipogenesis, and fibrosis. METHODS: Epicardial fat biopsies and blood were obtained from 151 non-selected patients undergoing open heart surgery. Immunohistochemistry, ELISA, or real-time PCR were used for analyzing protein or mRNA expression levels of CA125 and markers of inflammatory cells, fibroblasts, and adipocytes. Epithelial or stromal cells from epicardium were isolated and cultured to identify CA125 and its association with the adipogenesis and fibrosis pathways, respectively. RESULTS: The median age was 71 (63-74) years, 106 patients (70%) were male, and 62 (41%) had an established diagnosis of HF before surgery. The slice of epicardial fat biopsy determined a positive and colorimetric staining on the epithelial layer after incubating with the CA125 M11 antibody, providing the first description of CA125 expression in the human epicardium. Epicardial CA125 showed a strong and positive correlation with markers of inflammation and fibrosis in the epicardial fat tissue while exhibiting a negative correlation with markers of the adipogenesis pathway. This relationship remained significant after adjusting for potential confounders such as a prior HF diagnosis and plasma CA125 levels. CONCLUSION: Epicardial cells express CA125, which is positively associated with inflammatory and fibroblast markers in epicardial adipose tissue. These results suggest that CA125 may be biologically involved in HF progression (transition from adipogenesis to fibrosis).

ABSTRACT

Background: Cystic fibrosis transmembrane conductance regulator modulators are the only available treatment for cystic fibrosis. Although elexacaftor/tezacaftor/ivacaftor (ELX/TEZ/IVA) is well-tolerated, rash has been reported as very frequent. In severe rashes, ELX/TEZ/IVA withdrawal is necessary, leading to clinical deterioration. The objective of the study is to increment the experience of ELX/TEZ/IVA desensitization. Methods: Adult patients who developed a delayed hypersensitivity rash to ELX/TEZ/IVA between December 2021 and February 2023 and required withdrawal due to ineffective rescue medication were included. Skins test for ELX/TEZ/IVA and IVA were conducted to establish hypersensitivity mechanism. Balijepally ELX/TEZ/IVA desensitization protocol was selected. In cases where desensitization had to be discontinued due to rash, an extended desensitization was proposed. Clinical and health-related quality of life parameters were collected before ELX/TEZ/IVA and after desensitization. Results: 162 patients (81 women, 31.2 [23.8-42.5] years) started ELX/TEZ/IVA, developing rash 12 of them (7.4%, six women). Six patients (five women) required stopping ELX/TEZ/IVA and were selected for desensitization. Skin tests indicated delayed type-IV hypersensitivity in one patient. Two patients presented adequate tolerance to desensitization; while, four patients developed rash. Three of these patients, successfully concluded extended desensitization (one patient declined participation). No significant clinical deterioration or quality of life worsening was observed during desensitization; in fact, there was an improvement in practically all mesured parameters. All five patients who resumed ELX/TEZ/IVA are currently receiving therapy with good tolerance. Conclusion: Desensitization to ELX/TEZ/IVA could be a successful and safe strategy for reintroducing this essential treatment in cases of a delayed hypersensitivity rash.

ABSTRACT

Despite their ability to mitigate climate change by efficiently absorbing atmospheric carbon dioxide (CO2) and acting as natural long-term carbon sinks, mangrove ecosystems have faced several anthropogenic threats over the past century, resulting in a decline in the global mangrove cover. By using standardized methods and the most recent Bayesian tracer mixing models MixSIAR, this study aimed to quantify source contributions, burial rates, and stocks of organic carbon (Corg) and explore their temporal changes (∼100 years) in seven lead-210 dated sediment cores collected from three contrasting Mexican mangrove areas. The spatial variation in Corg burial rates and stocks in these blue carbon ecosystems primarily depended on the influence of local rivers, which controlled Corg sources and fluxes within the mangrove areas. The Corg burial rates in the cores ranged from 66 ± 16 to 400 ± 40 g m-2 yr-1. The Corg stocks ranged from 84.9 ± 0.7 to 255 ± 2 Mg ha-1 at 50 cm depth and from 137 ± 2 to 241 ± 4 Mg ha-1 at 1 m depth. The highest Corg burial rates and stocks were observed in cores from the carbonate platform of Yucatan and in cores with reduced river influence and high mangrove detritus inputs, in contrast to patterns identified from global databases. Over the past century, the rising trends in Corg burial rates and stocks in the study sites were primarily driven by enhanced inputs of fluvial-derived Corg and, in some cores, mangrove-derived Corg. Despite their decreasing extension, mangrove areas remained highly effective producers and sinks of Corg. Ongoing efforts to enhance the global database should continue, including mangrove area characteristics and reliable timescales to facilitate cross-comparison among studies.

ABSTRACT

INTRODUCTION AND OBJECTIVES: Pertrochanteric fractures constitute an important part of the daily activity of the orthopedic surgeon. The aim of this study was to carry out an analysis of pre-, intra- and post-operative radiographic parameters and to analyze the results of stable and unstable intertrochanteric fractures treated with short nails with dynamic distal locking. MATERIALS AND METHODS: Retrospective study in our center, between the years 2017-2021 of patients over 65 years of age with pertrochanteric fracture. We included 272 patients treated with Gamma3 Nail (Stryker®) with dynamic distal locking. As variables, we recorded: age, medical comorbidities, fracture pattern according to AO/OTA, osteopenia according to Singh's classification, pre-operative (such as diaphyseal extension), intra-operative (such as tip-to-the-apex or medial cortical support) and post-operative radiographic parameters (such as time to consolidation or loss of reduction), pre- and post-operative Barthel, quality of life and complications and reinterventions, such as non-union or cut-out. RESULTS: The mean age was 83.28 years (65-102). Two hundred four cases were women (75%). The average follow-up was 18.2 months (12-24). The distribution according to AO/OTA classification was 85.7% 31.A1; 12.5% 31.A2; 1.9% 31.A3. Radiographic consolidation was obtained in 97.4% of cases. Tip to apex distance was less than 25mm in 95.6% of cases. Medial cortical support was positive or neutral in 88.6% of cases. Sixty cases (22.1%) of screw back-out were recorded. Eight reinterventions (2.9%) were performed, corresponding to three cut-outs (1.1%), three non-unions (1.1%), one avascular necrosis (0.4%) and one secondary hip osteoarthritis (0.4%). CONCLUSIONS: Short nail with dynamic distal locking offers good clinical, radiological and functional results in all types of AO/OTA patterns, without increasing the complication rate, as long as there is an appropriate tip-to-the-apex distance and good medial cortical support.

ABSTRACT

INTRODUCTION: The course in Primary Care in Pediatric Trauma (ATIP in Spanish) has been taught in Spain since 1997, and there are currently 9 accredited training centers. Care of polytraumatized pediatric patients often takes place in an environment conducive to errors resulting from forgetfulness, which is why checklists - mnemonic tools widely used in industry and medicine - are particularly useful to avoid such errors. Although several checklists exist for pediatric trauma care, none have been developed within the setting of our course. MATERIALS AND METHODS: The criteria for being selected as an expert in Primary Care in Pediatric Trauma were agreed upon with the scientific polytrauma committee of the Spanish Pediatric Surgery Society. The items that make up the checklist were obtained from a review of the literature and consultation with selected experts, using the Delphi Technique. RESULTS: 10 experts representing the 9 groups or training centers in Primary Care in Pediatric Trauma were selected, and a 28-item checklist was drawn up in accordance with their design recommendations. CONCLUSIONS: With the consensus of all the groups, a checklist for the treatment of polytraumatized pediatric patients was drawn up using the Delphi Technique, an essential requirement for the dissemination of this checklist, which should be adapted and validated for use in each healthcare center.


INTRODUCCION: El curso de Asistencia Inicial al Trauma Pediátrico se imparte en España desde 1997, existiendo en la actualidad 9 centros formadores acreditados. La asistencia al paciente pediátrico politraumatizado se produce muchas veces en un ambiente proclive al error por olvido, por lo que las listas de verificación, como herramientas mnemotécnicas de amplia difusión en la industria y en medicina, serían especialmente útiles para evitarlos. Aunque existen varias listas de verificación para la asistencia al traumatismo pediátrico, ninguna se ha desarrollado en el entorno de nuestro curso. MATERIAL Y METODOS: Se acordaron los criterios para ser seleccionado como experto en Asistencia Inicial al Trauma Pediátrico con la comisión científica de politrauma de la Sociedad Española de Cirugía Pediátrica. Los ítems para formar la lista de verificación se obtuvieron a partir de una revisión bibliográfica y de la consulta a los expertos seleccionados, empleando un método Delphi. RESULTADOS: Se seleccionaron 10 expertos que representan los 9 grupos o centros formadores en Asistencia Inicial al Trauma Pediátrico y se elaboró una lista de verificación con 28 ítems, siguiendo sus recomendaciones de diseño. CONCLUSIONES: Se diseñó una lista de verificación para el manejo del paciente pediátrico politraumatizado, con el consenso de todos los grupos empleando un método Delphi, requisito fundamental para facilitar la difusión de esta lista. Sería preciso adaptar y validar dicha lista para su uso en cada centro asistencial.

ABSTRACT

OBJECTIVE: This article aims to estimate the differences in environmental impact (greenhouse gas [GHG] emissions, land use, energy used, acidification and potential eutrophication) after one year of promoting a Mediterranean diet (MD). METHODS: Baseline and 1-year follow-up data from 5800 participants in the PREDIMED-Plus study were used. Each participant's food intake was estimated using validated semi-quantitative food frequency questionnaires, and the adherence to MD using the Dietary Score. The influence of diet on environmental impact was assessed through the EAT-Lancet Commission tables. The influence of diet on environmental impact was assessed through the EAT-Lancet Commission tables. The association between MD adherence and its environmental impact was calculated using adjusted multivariate linear regression models. RESULTS: After one year of intervention, the kcal/day consumed was significantly reduced (-125,1 kcal/day), adherence to a MD pattern was improved (+0,9) and the environmental impact due to the diet was significantly reduced (GHG: -361 g/CO2-eq; Acidification:-11,5 g SO2-eq; Eutrophication:-4,7 g PO4-eq; Energy use:-842,7 kJ; and Land use:-2,2 m2). Higher adherence to MD (high vs. low) was significantly associated with lower environmental impact both at baseline and one year follow-up. Meat products had the greatest environmental impact in all the factors analysed, both at baseline and at one-year follow-up, in spite of the reduction observed in their consumption. CONCLUSIONS: A program promoting a MD, after one year of intervention, significantly reduced the environmental impact in all the factors analysed. Meat products had the greatest environmental impact in all the dimensions analysed.

ABSTRACT

The allergenicity and protein risk assessments in food safety are facing new challenges. Demands for healthier and more sustainable food systems have led to significant advances in biotechnology, the development of more complex foods, and the search for alternative protein sources. All this has increased the pressure on the safety assessment prediction approaches anchored into requirements defined in the late 90's. In 2022, the EFSA's Panel on Genetically Modified Organisms published a scientific opinion focusing on the developments needed for allergenicity and protein safety assessments of new products derived from biotechnology. Here, we further elaborate on the main elements described in this scientific opinion and prioritize those development needs requiring critical attention. The starting point of any new recommendation would require a focus on clinical relevance and the development of a fit-for-purpose database targeted for specific risk assessment goals. Furthermore, it is imperative to review and clarify the main purpose of the allergenicity risk assessment. An internationally agreed consensus on the overall purpose of allergenicity risk assessment will accelerate the development of fit-for-purpose methodologies, where the role of exposure should be better clarified. Considering the experience gained over the last 25 years and recent scientific developments in the fields of biotechnology, allergy, and risk assessment, it is time to revise and improve the allergenicity safety assessment to ensure the reliability of allergenicity assessments for food of the future.

ABSTRACT

Neuronal aging may be, in part, related to a change in DNA methylation. Thus, methyl donors, like folate and methionine, may play a role in cognitive changes associated to neuronal aging. To test the role of these metabolites, we performed stereotaxic microinjection of these molecules into the dentate gyrus (DG) of aged mice (an average age of 21 month). Folate, but not S-Adenosyl-Methionine (SAM), enhances cognition in aged mice. In the presence of folate, we observed partial rejuvenation of DG cells, characterized by the expression of juvenile genes or reorganization of extracellular matrix. Here, we have also tried to identify the mechanism independent of DNA methylation, that involve folate effects on cognition. Our analyses indicated that folate binds to folate receptor α (FRα) and, upon folate binding, FRα is transported to cell nucleus, where it is acting as transcription factor for expressing genes like SOX2 or GluN2B. In this work, we report that a FRα binding peptide also replicates the folate effect on cognition, in aged mice. Our data suggest that such effect is not sex-dependent. Thus, we propose the use of this peptide to improve cognition since it lacks of folate-mediated side effects. The use of synthetic FRα binding peptides emerge as a future strategy for the study of brain rejuvenation.

ABSTRACT

BACKGROUND: The HER2DX risk-score has undergone rigorous validation in prior investigations involving patients with early-stage human epidermal growth factor receptor 2 (HER2)-positive (HER2+) breast cancer. In this study, we present the outcomes of the HER2DX risk-score within the most recent release of the Sweden Cancerome Analysis Network-Breast (SCAN-B) HER2+ cohort. This updated examination benefits from a larger patient sample, an extended follow-up duration, and detailed treatment information. MATERIALS AND METHODS: Clinical and RNAseq data from the SCAN-B dataset were retrieved from Gene Expression Omnibus (GSE81538). Among the 6600 patients, 819 had HER2+ breast cancer, with 757 individuals with research-based HER2DX risk-scores and corresponding survival outcomes. The HER2DX risk-score was evaluated (i) as a continuous variable and (ii) using predefined cut-offs. The primary endpoint for this study was overall survival (OS). The Kaplan-Meier method and Cox models were used to estimate OS and a multistate model with four states was fitted to better characterize patients' follow-up. RESULTS: The median follow-up time was 7.5 years (n = 757). The most common systemic therapy was chemotherapy with trastuzumab (82.0%) and most tumors were classified as T1-T2 (97.1%). The HER2DX risk-score as a continuous variable was significantly associated with OS after adjustment for clinical variables and treatment regimen [hazard ratios (HR) per 10-unit increment = 1.31, 95% confidence interval (CI) 1.13-1.51, P < 0.001] as well as within predefined risk groups (high versus low; HR = 2.57, 95% CI 1.36-4.85, P < 0.001). Patients classified as HER2DX high-risk also had higher risk of (i) breast cancer recurrence and (ii) death without previous recurrence. Within the subgroup of HER2+ T1N0 tumors (n = 297), those classified as high-risk demonstrated inferior OS compared to low-risk tumors (7-year OS 77.8% versus 96.8%, P < 0.001). The HER2DX mRNA ERBB2 score was associated with clinical HER2 status (area under the receiver operating characteristic curve = 0.91). CONCLUSIONS: In patients with early-stage HER2+ breast cancer, HER2DX risk-score provides prognostic information beyond clinicopathological variables, including treatment regimen with or without trastuzumab.

ABSTRACT

Duddingtonia flagrans is a nematophagous fungus which has shown promising results as a non-chemical parasitic control tool. The fungus disrupts the parasite's life cycle by trapping larvae in the environment through the networks generated from chlamydospores, thus preventing the reinfection of animals. One barrier to the development of a commercial product using this tool is the need to increase chlamydospore production in the laboratory for its administration to livestock. The purpose of this study was to evaluate the addition of mannitol to an enriched culture medium and the effect of adverse cultivation conditions on chlamydospore production. D. flagrans was cultivated on Petri dishes with corn agar for 4 weeks at 27 °C and 70% relative humidity (RH). Four groups were then formed, all with Sabouraud agar as a base, to which different growth inducers were added: GSA (glucose Sabouraud agar), GSA-MI (glucose Sabouraud agar + meso inositol), GSA-E (enriched glucose Sabouraud agar), and AE-M (enriched agar + mannitol). After 4 weeks, chlamydospores were recovered by washing the surface of each plate with distilled water and then quantified. The medium that yielded the highest amount of chlamydospores was subjected to different cultivation conditions: NC (normal conditions): 70% RH and 27 °C, AC (adverse conditions) 1: 20% RH and 40 °C, CA2: 60% RH and 27 °C, and CA3: 55% RH and 24 °C. It was determined that mannitol increases chlamydospore production (65x106 chlamydospores/plate), and when reducing humidity by 10% under cultivation conditions it resulted in an approximately 10% increase in chlamydospore production compared to the control group. These results suggest that the addition of polyols, as well as its cultivation under certain environmental conditions, can improve chlamydospore production on a laboratory scale.

ABSTRACT

INTRODUCTION: During the SARS-CoV-2 pandemic, several corticosteroid regimens have been used in the treatment of the disease, with disparate results according to drug and regimen used. For this reason, we wanted to analyze differences in early mortality derived from the use of different regimens of dexamethasone and methylprednisolone in SARS-CoV-2 infection in critically ill patients requiring admission to an ICU. METHOD: Observational, analytical and retrospective study, in an intensive care unit of a third-level university hospital, (March 2020 and June 2021). Adult patients (>18 years old) who were admitted consecutively for proven SARS-CoV-2 infection were included. The association with mortality in ICU at 28 days, different corticosteroid regimens used, was analyzed using a Cox proportional risk regression model. RESULTS: Data from a cohort of 539 patients were studied. Patient age (RR: 1.06; 95% CI: 1.02-1.10; P=<0.01) showed a significant association with 28-day mortality in the ICU. In the comparison of the different corticosteroid regimens analyzed, taking as a reference those patients who did not receive corticosteroid treatment, the dose of dexamethasone of 6mg/day showed a clear trend towards statistical significance as a protector of mortality at 28 days in the ICU (RR: 0.40, 95% CI: 0.15-1.02, p=0.05). The dose of dexamethasone of 6mg/day and low doses of methylprednisolone show a similar association with survival at 28 days (OR: 1.19; 95% CI: 0.63-2.26). CONCLUSIONS: The use of corticosteroids has been associated with better mortality outcomes in severe cases of SARS-CoV-2 infection. However, the therapeutic benefits of corticosteroids are not limited to dexamethasone alone.

ABSTRACT

The global population growth has significantly impacted energy and raw material consumption, unmatched since the Industrial Revolution. Among metals, aluminium ranks second only to steel, with annual production exceeding 69 million tonnes. Due to its high demand, bauxite, the primary ore from which aluminium is extracted, is now classified as a critical material in the EU and the US, given the potential risk of supply shortages for essential applications. Geographical and production challenges surround bauxite, presenting geo-economic and environmental challenges. A critical concern in aluminium production is managing by-products, notably red mud, a bauxite residue, generating over 175 million tonnes annually worldwide. Comprehensive bibliometric research is imperative due to the high amount of bibliographical resources related to this topic, encompassing circular economy, re-valorisation, sustainability, and disposal. This study employs bibliometric methods to assess red mud valorisation, offering insights into research topics, influential authors, and key journals, shedding light on the past, present, and future of red mud research. Such bibliometric analysis not only highlights the current state of the field but also serves as a valuable tool for decision-making, enabling researchers and policymakers to identify trends, gaps, and areas for further exploration, fostering informed and sustainable advancements in the by-products of the aluminium industry.

ABSTRACT

INTRODUCTION: Currently, there is a lack of prospective studies to unify criteria about type and time for postoperative immobilisation in surgical distal radius fractures. The aim of this study is to compare functional and radiological results in two groups of distal radius fractures treated with internal fixation with locking plate, and immobilised with antebrachial splint or compression bandage for 3 weeks. MATERIAL AND METHOD: A randomised clinical trial was carried out with two parallel groups with 3, 6, and 12 weeks of follow-up. Main and secondary functional variables were measured, such as pain on VAS scale, values on PRWE, DASH and MRS scale, range of motion in flexion-extension, complications, etc. In addition, some radiological variables were measured at preoperative period and one week after surgery, such as union time, dorsal displacement, shortening, ulnar variance, etc. RESULTS: A total of 62 patients were evaluated: 27 immobilised with bandage and 35 with splint. Analysis of the results obtained showed significant differences in both groups for almost all radiological variables from pre to postoperative period, and for all functional variables from 3 to 12 weeks after surgery. No significant differences were found between the two groups for any of the radiological and functional variables evaluated (VAS 3-12 weeks: p=.584; PWRE 3-12 weeks: p=.248; flexion range of motion 3-12 weeks: p=.959; extension range of motion: p=.50; union time: p=.89). CONCLUSIONS: We do not find clinical or radiological differences between immobilisation with antebrachial splint or compression bandage for distal radius fractures operated with locking plate. A greater number of patients and follow-up are necessary to extrapolate the results to the general population and to establish criteria for good postoperative management of these fractures.

ABSTRACT

This study describes 5 mediastinitis cases secondary to invasive group A Streptococcus (iGAS) disease in a recent outbreak in Spain. Among 398 iGAS cases between January 2019-March 2023, 5 (1.3%) were mediastinitis, 4 occurring in December 2022, all secondary to pneumonia or deep neck infection. We outline the clinical outcome with a review of the scarce pediatric literature.  Conclusion: mediastinistis is a rare but severe complication of iGAS and a high level of suspicion is required to diagnose it. What is Known: • Group A Streptococcus can cause invasive and severe infections in children. • Mediastinitis is a severe complication from some bacterial infections, mainly secondary due to deep-neck abscesses. What is New: • Mediastinitis is an unrecognized complication due to an invasive group A Streptococcus (iGAS) infection. • In cases of a deep-neck abscess or complicated pneumonia a high clinical suspicion of iGAS mediastinitis is required, especially when the clinical course is not favorable.
