The genomic profiling of high-risk smoldering myeloma patients treated with an intensive strategy unveils potential markers of resistance and progression.

Smoldering multiple myeloma (SMM) precedes multiple myeloma (MM). The risk of progression of SMM patients is not uniform, thus different progression-risk models have been developed, although they are mainly based on clinical parameters. Recently, genomic predictors of progression have been defined for untreated SMM. However, the usefulness of such markers in the context of clinical trials evaluating upfront treatment in high-risk SMM (HR SMM) has not been explored yet, precluding the identification of baseline genomic alterations leading to drug resistance. For this reason, we carried out next-generation sequencing and fluorescent in-situ hybridization studies on 57 HR and ultra-high risk (UHR) SMM patients treated in the phase II GEM-CESAR clinical trial (NCT02415413). DIS3, FAM46C, and FGFR3 mutations, as well as t(4;14) and 1q alterations, were enriched in HR SMM. TRAF3 mutations were specifically associated with UHR SMM but identified cases with improved outcomes. Importantly, novel potential predictors of treatment resistance were identified: NRAS mutations and the co-occurrence of t(4;14) plus FGFR3 mutations were associated with an increased risk of biological progression. In conclusion, we have carried out for the first time a molecular characterization of HR SMM patients treated with an intensive regimen, identifying genomic predictors of poor outcomes in this setting.

Detection of Aeromonas salmonicida subsp. salmonicida infection in zebrafish by labelling bacteria with GFP and a fluorescent probe based on the siderophore amonabactin.

Zebrafish (Danio rerio) is an excellent model to study bacterial infections in fish and their treatment. We used zebrafish as a model of infection for Aeromonas salmonicida subsp. salmonicida (hereinafter A. salmonicida), the causative agent of fish furunculosis. The infection process of A. salmonicida was studied by immersion of zebrafish larvae in 2 different doses of the bacteria and the fish mortality was monitored for three days. The bacterium caused a high mortality (65 %) in zebrafish larvae only when they were exposed to a high bacterial concentration (107 bacterial cells/mL). To evaluate the use of fluorescence microscopy to follow A. salmonicida infection in vivo, two different fluorescent strains generated by labeling an A. salmonicida strain with either, the green fluorescent protein (GFP), or with a previously reported siderophore amonabactin-sulforhodamine B conjugate (AMB-SRB), were used. The distribution of both labeled bacterial strains in the larvae tissues was evaluated by conventional and confocal fluorescence microscopy. The fluorescent signal showed a greater intensity with the GFP-labeled bacteria, so it could be observed using conventional fluorescence microscopy. Since the AMB-SRB labeled bacteria showed a weaker signal, the larvae were imaged using a laser scanning confocal microscope after 48 h of exposure to the bacteria. Both fluorescent signals were mainly observed in the larvae digestive tract, suggesting that this is the main colonization route of zebrafish for waterborne A. salmonicida. This is the first report of the use of a siderophore-fluorophore conjugate to study a bacterial infection in fish. The use of a siderophore-fluorophore conjugate has the advantage that it is a specific marker and that does not require genetic manipulation of the bacteria.

Farmacia hospitalaria ecológica: un enfoque sostenible del proceso de utilización de medicamentos en un hospital de tercer nivel / Green hospital pharmacy: A sustainable approach to the medication use process in a tertiary hospital

Background Sustainable management of healthcare waste has a positive impact on the global environment. In order to reduce it, the sustainable practice of the pharmacotherapeutic process in all its stages is essential. Objective To analyze the sustainability strategies proposed by the pharmacy service to reduce drug waste derived from the pharmacotherapeutic process. Secondary objectives: to analyze the stage of the pharmacotherapeutic process and the number and type of drugs involved. Methods The study was carried out in a tertiary level hospital. To coordinate the proposals, a referent pharmacist from every pharmacy department area was selected. Four stages of the process were evaluated (procurement, validation, dispensing and compounding), patients concerned were classified as outpatients or inpatients, and drugs potentially involved were analyzed by the administration route: into oral or parenteral. Results 28 ideas were proposed, which could affect more than 1200 drugs. 39.3% would affect the validation process, 17.9% the procurement management, 17.9% dispensing and 7.1% the compounding. Implementation feasibility and acceptability of these proposals were evaluated. Those with the greatest potential were: limiting the duration of treatments when possible, favoring the implementation of computer prescription order entry, favoring the use of the oral route over the parenteral route, and implementing computers in the preparation areas to avoid the use of paper guides. Discussion In our study, many ideas have been proposed by hospital pharmacists to improve the sustainability of the medication use process. When assessing these proposals by impact and feasibility, according to our results, shorten as much as possible the duration of treatments, computerization of the medication use process and oral administration over intravenous should be prioritized in order to reduce environmental impact.

Machine learning dislocation density correlations and solute effects in Mg-based alloys.

Magnesium alloys, among the lightest structural materials, represent excellent candidates for lightweight applications. However, industrial applications remain limited due to relatively low strength and ductility. Solid solution alloying has been shown to enhance Mg ductility and formability at relatively low concentrations. Zn solutes are significantly cost effective and common. However, the intrinsic mechanisms by which the addition of solutes leads to ductility improvement remain controversial. Here, by using a high throughput analysis of intragranular characteristics through data science approaches, we study the evolution of dislocation density in polycrystalline Mg and also, Mg-Zn alloys. We apply machine learning techniques in comparing electron back-scatter diffraction (EBSD) images of the samples before/after alloying and before/after deformation to extract the strain history of individual grains, and to predict the dislocation density level after alloying and after deformation. Our results are promising given that moderate predictions (coefficient of determination [Formula: see text] ranging from 0.25 to 0.32) are achieved already with a relatively small dataset ([Formula: see text] 5000 sub-millimeter grains).

Epidemiology, clinical and imaging features of rhombencephalitis caused by L. monocytogenes. A retrospective observational study. / Epidemiología, clínica y resultados de imagen de rombencefalitis causada por L. monocytogenes. Un estudio observacional.

INTRODUCTION: To date, few studies have explored the specific risk factors of patients with listeriosis who develop rhombencephalitis, and there is insufficient information regarding imaging findings and clinical symptoms in patients with this disease. This work aimed to analyze the imaging findings associated with L. monocytogenes rhombencephalitis in a cohort of patients with listeriosis. MATERIALS AND METHODS: We conducted a retrospective observational study of all declared cases of listeriosis in a tertiary hospital from Granada, Spain, from 2008 to 2021. Risk factors, comorbidities, and clinical outcomes were collected for all patients. In addition, clinical symptoms and magnetic resonance imaging (MRI) findings were included for those patients who developed rhombencephalitis. Descriptive and bivariate analyses were performed using SPSS statistical software (IBM SPSS, version 21). RESULTS: Our cohort comprised 120 patients with listeriosis (41.7% women, mean age: 58.6 ± 23.8 years), of which 10 (8.3%) had rhombencephalitis. The most frequent MRI findings in patients with confirmed rhombencephalitis were T2-FLAIR hyperintensity (100%), T1 hypointensity (80%), scattered parenchymal enhancement (80%), and cranial nerve enhancement (70%), while the most frequent anatomical involvement were pons, medulla oblongata, and cerebellum. Complications occurred in 6 patients (abscess in 4, hemorrhage in 2, hydrocephalus in 1). CONCLUSIONS: Rhombencephalitis is associated with an increased in-hospital mortality in patients with listeriosis. The anatomical distribution and imaging characteristics of neurolisteriosis could be useful to suggest the diagnosis. Future studies with greater sample size should explore the association between anatomical location, imaging patterns, and associated complications (e.g., hydrocephalus, hemorrhage), and clinical outcomes.

Un año de seguimiento con variabilidad de la frecuencia cardiaca en trail runners / One-year follow-up with heart rate variability in trail runners

Este estudio tuvo como objetivo analizar las medidas de variabilidad de la frecuencia cardíaca (VFC) para proporcionar valores de referencia en atletas de Ultra-Trail Running (UTR). Dieciséis UTR chilenos fueron monitoreados con registros basales al despertar de 5 minutos durante un año de seguimiento, tiempo en el cual, mantuvieron sus actividades habituales de entrenamiento, competición y descanso. Como variable para evaluar la actividad parasimpática la RMSSD (raíz cuadrada de la media de las diferencias de la suma de los cuadrados entre intervalos RR adyacentes) fue analizada. Además, se calculó el Stress Score (SS) como indicador de la actividad simpática. Los datos aportados proporcionan valores de referencia de VFC para UTR a través de una distribución de percentiles, que pueden ser particularmente útiles cuando la VFC se utiliza para el control de las cargas de entrenamiento en atletas de UTR. (AU)

This study aimed to analyze measures of heart rate variability (HRV) to provide reference values in Ultra-Trail Running (UTR) athletes. Sixteen Chilean UTR were monitored with 5-minute baseline wake-up records during a one-year follow-up during which they maintained their usual training, competition and rest activities. As a variable to evaluate parasympathetic activity the RMSSD (square root of the mean value of the sum of the squared differences of all successive RR intervals) was analyzed. In addition, the Stress Score (SS) was calculated as an indicator of sympathetic activity. The data provided are reference baseline HRV values for UTR through a percentile distribution, which can be particularly useful when HRV is used to control training loads in UTR athletes. (AU)

NUT carcinoma of the mandible in a child: case report and systematic review.

Nuclear protein of the testis (NUT) carcinoma is a rare, undifferentiated carcinoma that is characterized by NUTM1 gene rearrangements. Patients with NUT carcinoma have an overall survival of approximately 5% at 5 years despite a multimodal treatment approach. This report illustrates the management of mandibular NUT carcinoma in a pediatric patient, complemented by a systematic review of head and neck NUT carcinoma. A 5-year-old female presented with an enlarging jaw mass that was diagnosed as BRD4-NUTM1 carcinoma and was treated with hemimandibulectomy and chemoradiation. She remains disease-free 21 months after completion of therapy. A total of 63 patient cases reported in 34 articles were identified in the review. Only 26.9% (14/52) of tumors were correctly diagnosed initially as NUT carcinoma, whereas 73.1% (38/52) were incorrectly diagnosed as another malignancy; the initial diagnosis was not reported for 11 patients. The mandibular tumor subtype was among the rarest reported (n = 1; 1.6%). Combination therapy, including surgery and chemoradiation, was the most common treatment (55.2%). The patient case presented here is a novel case of pediatric mandibular NUT carcinoma. Due to the poor overall survival of patients with NUT carcinoma, aggressive upfront resection with 2-cm margins followed by adjuvant chemoradiation is advocated.

The use of digital escape rooms in nursing education.

Negative attitudes and prejudices towards people with a mental disorder are common across cultures and societies. The stigma associated with mental illness leads to a lower quality of life, given the discrimination and social exclusion suffered by people with this type of disorder. In the field of health, research has shown that doctors and nurses also manifest these types of stigmatizing behaviors and attitudes. The present study aims to create and apply an educational escape room for the purpose of training nursing students in mental health, promoting positive attitudes towards people who have a mental disorder. To do so, a pre-post study was conducted with an experimental group and a control group to determine whether the escape room was effective for the modification of stigmatizing behaviors compared to transmissive lecture class, and a third measurement was made at 6 months only to the experimental group to evaluate whether the changes produced by the escape room were maintained in the long term. The results indicate that the students participating in the study obtained better scores in sensitization and these remain better over time. It is concluded that the escape room used is suitable for the training and sensitization of future nursing professionals in the field of mental health, facilitating the learning of knowledge and positive attitudes towards severe mental disorder.

Borrasca Filomena: pie de trinchera en España en tiempos de paz / Storm «Philomena»: trench foot in peacetime in Spain

El pie de trinchera es considerada la lesión militar más frecuente no relacionada con el combate y conocemos de su existencia desde tiempos de Napoleón. Sin embargo, esta vasoneuropatía sigue siendo una condición poco conocida y, por ende, un desafío diagnóstico. Con la presentación de dos casos clínicos atendidos en nuestro hospital durante la borrasca Filomena, ocurrida en España en enero del 2021, con Madrid como una de las zonas más afectadas, pretendemos aportar un poco más de conocimiento, en aras de mejorar la identificación de los casos y el correcto manejo terapeútico que, a buen seguro, mejorará el pronóstico de nuestros pacientes, sin olvidar las medidas preventivas. En nuestra experiencia ha sido determinante un riguroso estudio diagnóstico (vascular y electroneurofisiológico) y el tratamiento vasodilatador con bloqueo ciático poplíteo, inhibidores de la 5 fosfodiesterasa y calcioantagonistas dihidropiridínicos.(AU)

Trench foot is considered the most common non-combat related military injury and we have known of its existance since Napoleon’s time. However, this vasoneuropathy remains a poorly understood condition and, therefore, a diagnostic challenge. With the report of 2 clinical cases treated in our hospital during Filomena storm, which occurred in Spain in January 2021, with Madrid as one of the most affected areas, we intend to contribute a little more knowledge, in order to improve cases identification and the correct management that, surely will improve our patients prognosis, without forgetting preventive measures. In our experience, a rigorous diagnostic study (vascular and electroneurophysiological) and a vasodilatador treatment with sciatic popliteal block, 5-phosphodiesterase inhibitors and dihydropyridine calcium antagonists have been decisive.(AU)

Tratamiento de las infecciones graves por Pseudomonas aeruginosa multirresistente / Treatment of severe multi-drug resistant Pseudomonas aeruginosa infections

Pseudomonas aeruginosa es el microorganismo que participa con mayor frecuencia en las principales infecciones adquiridas en la UCI, con especial importancia en la neumonía asociada a ventilación mecánica. Su importancia radica, además de en su elevada incidencia en el paciente crítico, en la gravedad de las infecciones que causa y en la dificultad de su tratamiento antimicrobiano, directamente relacionada con el elevado porcentaje de resistencias a los antibióticos considerados clásicamente de primera línea. Recientemente se han desarrollado nuevos antibióticos activos frente a Pseudomonas aeruginosa, incluso frente a cepas multirresistentes. La presente revisión analiza tanto las características diferenciales de las infecciones por Pseudomonas aeruginosa como las nuevas opciones terapéuticas, centrando el foco en la Pseudomonas aeruginosa multirresistente (AU)

Pseudomonas aeruginosa is the microorganism most frequently involved in the main ICU-acquired infections, with special importance in ventilator associated pneumonia. Its importance lies, in addition to its high incidence in critically ill patients, in the severity of the infections it causes and in the difficulty of its antimicrobial treatment, directly related to the high percentage of resistance to antibiotics classically considered first-line. New active antibiotics have recently been developed against Pseudomonas aeruginosa, even against multi-drug resistant strains. This review analyzes both the differential characteristics of Pseudomonas aeruginosa infections and the new therapeutic options, focusing on multi-drug resistant Pseudomonas aeruginosa (AU)

Identification of Small, Regularly Shaped Cerebral Aneurysms Prone to Rupture.

BACKGROUND AND PURPOSE: Many small, regularly shaped cerebral aneurysms rupture; however, they usually receive a low score based on current risk-assessment methods. Our goal was to identify patient and aneurysm characteristics associated with rupture of small, regularly shaped aneurysms and to develop and validate predictive models of rupture in this aneurysm subpopulation. MATERIALS AND METHODS: Cross-sectional data from 1079 aneurysms smaller than 7 mm with regular shapes (without blebs) were used to train predictive models for aneurysm rupture using machine learning methods. These models were based on the patient population, aneurysm location, and hemodynamic and geometric characteristics derived from image-based computational fluid dynamics models. An independent data set with 102 small, regularly shaped aneurysms was used for validation. RESULTS: Adverse hemodynamic environments characterized by strong, concentrated inflow jets, high speed, complex and unstable flow patterns, and concentrated, oscillatory, and heterogeneous wall shear stress patterns were associated with rupture in small, regularly shaped aneurysms. Additionally, ruptured aneurysms were larger and more elongated than unruptured aneurysms in this subset. A total of 5 hemodynamic and 6 geometric parameters along with aneurysm location, multiplicity, and morphology, were used as predictive variables. The best machine learning rupture prediction-model achieved a good performance with an area under the curve of 0.84 on the external validation data set. CONCLUSIONS: This study demonstrated the potential of using predictive machine learning models based on aneurysm-specific hemodynamic, geometric, and anatomic characteristics for identifying small, regularly shaped aneurysms prone to rupture.

Radiographic differences observed following apexification vs revascularization in necrotic immature molars and incisors: a follow-up study of 18 teeth.

PURPOSE: To evaluate the effectiveness of apexification versus revascularization in the treatment of necrotic immature teeth and determine which strategy affords the greatest radiological success rate. METHODS: An analysis was made of 18 teeth subjected to mineral trioxide aggregate (MTA) apical plugging and regenerative endodontic treatment, assessing healing of the apical lesions and the changes in root dimensions. RESULTS: Significantly greater root growth was observed with revascularization in terms of the percentage change in length (12.75% at 6 months) and dentin thickness (34.57% at 6 months) (p < 0.05). There were no significant differences between the two treatments in terms of the apical healing scores after 6 months of follow-up (p > 0.05). CONCLUSION: Apexification with an MTA apical plug and pulp regeneration are reliable treatments for non-vital immature teeth. The radiographic outcomes are comparable between the immature teeth subjected to MTA apexification versus those subjected to revascularization. The results of the present study indicate a greater increase in root length and width with regenerative endodontic treatment.

Imaging of therapeutic airway interventions in thoracic oncology.

Tracheobronchial obstruction, haemoptysis, and airway fistulas caused by airway involvement by primary or metastatic malignancies may result in dyspnoea, wheezing, stridor, hypoxaemia, and obstructive atelectasis or pneumonia, and can lead to life-threatening respiratory failure if untreated. Complex minimally invasive endobronchial interventions are being used increasingly to treat cancer patients with tracheobronchial conditions with curative or, most often, palliative intent, to improve symptoms and quality of life. The selection of the appropriate treatment strategy depends on multiple factors, including tumour characteristics, whether the lesion is predominately endobronchial, shows extrinsic compression, or a combination of both, the patient's clinical status, the urgency of the clinical scenario, physician expertise, and availability of tools. Pre-procedure multidetector computed tomography (MDCT) imaging can aid in the most appropriate selection of bronchoscopic treatment. Follow-up imaging is invaluable for the early recognition and management of any potential complication. This article reviews the most commonly used endobronchial procedures in the oncological setting and illustrates the role of MDCT in planning, assisting, and follow-up of endobronchial therapeutic procedures.

Arabic gum plus colistin coated moxifloxacin-loaded nanoparticles for the treatment of bone infection caused by Escherichia coli.

Osteomyelitis is an inflammatory process of bone and bone marrow that may even lead to patient death. Even though this disease is mainly caused by Gram-positive organisms, the proportion of bone infections caused by Gram-negative bacteria, such as Escherichia coli, has significantly increased in recent years. In this work, mesoporous silica nanoparticles have been employed as platform to engineer a nanomedicine able to eradicate E. coli- related bone infections. For that purpose, the nanoparticles have been loaded with moxifloxacin and further functionalized with Arabic gum and colistin (AG+CO-coated MX-loaded MSNs). The nanosystem demonstrated high affinity toward E. coli biofilm matrix, thanks to AG coating, and marked antibacterial effect because of the bactericidal effect of moxifloxacin and the disaggregating effect of colistin. AG+CO-coated MX-loaded MSNs were able to eradicate the infection developed on a trabecular bone in vitro and showed pronounced antibacterial efficacy in vivo against an osteomyelitis provoked by E. coli. Furthermore, AG+CO-coated MX-loaded MSNs were shown to be essentially non-cytotoxic with only slight effect on cell proliferation and mild hepatotoxicity, which might be attributed to the nature of both antibiotics. In view of these results, these nanoparticles may be considered as a promising treatment for bone infections caused by enterobacteria, such as E. coli, and introduce a general strategy against bone infections based on the implementation of antibiotics with different but complementary activity into a single nanocarrier. STATEMENT OF SIGNIFICANCE: In this work, we propose a methodology to address E.coli bone infections by using moxifloxacin-loaded mesoporous silica nanoparticles coated with Arabic gum containing colistin (AG+CO-coated MX-loaded MSNs). The in vitro evaluation of this nanosystem demonstrated high affinity toward E. coli biofilm matrix thanks to the Arabic gum coating, a disaggregating and antibacterial effect of colistin, and a remarkable antibiofilm action because of the bactericidal ability of moxifloxacin and colistin. This anti-E. coli capacity of AG+CO-coated MX-loaded MSNs was brought out in an in vivo rabbit model of osteomyelitis where the nanosystem was able to eradicate more than 90% of the bacterial load within the infected bone.
