ABSTRACT

OBJECTIVES: In MOG antibody-associated disease (MOGAD), relapse prevention and the treatment approach to refractory symptoms are unknown. We report a patient with refractory MOGAD treated with CD19-directed CAR T-cells. METHODS: CD19-directed CAR T-cells (ARI-0001) were produced in-house by lentiviral transduction of autologous fresh leukapheresis and infused after a conventional lymphodepleting regimen. RESULTS: A 18-year-old man developed 2 episodes of myelitis associated with serum MOG-IgG, which were followed by 6 episodes of left optic neuritis (ON) and sustained the presence of MOG-IgG over 6 years despite multiple immunotherapies. After the sixth episode of ON, accompanied by severe residual visual deficits, CAR T-cell treatment was provided without complications. Follow-up of cell counts showed complete depletion of CD19+ B cells at day +7; reconstituted B cells at day +141 showing a naïve B-cell phenotype, and low or absent memory B cells and plasmablasts for 1 year. MOG-IgG titers have remained undetectable since CAR T-cell infusion. The patient had an early episode of left ON at day +29, when MOG-IgG was already negative, and since then he has remained free of relapses without immunotherapy for 1 year. DISCUSSION: This clinical case shows that CD19-directed CAR T-cell therapy is well-tolerated and is a potential treatment for patients with refractory MOGAD. CLASSIFICATION OF EVIDENCE: This provides Class IV evidence. It is a single observational study without controls.

ABSTRACT

BACKGROUND: There is limited recent evidence about infective endocarditis (IE) in HIV-infected patients. Our aim was to compare IE according to HIV infection presence. METHODS: Consecutive inclusion of IE patients at 46 Spanish hospitals between 2008 and 2021. RESULTS: From 5667 patients, 99 were HIV-infected (1·7%; 50 intravenous drugs users). Compared to patients without HIV, HIV-infected patients were more frequently male (84% vs. 67%), had younger median age (46 vs. 69 years), and less comorbidities, except liver disease (52% vs. 9%) and intravenous drug use (51% vs. 1%). They had more common tricuspid location (36% vs. 5%) and community-acquired IE (82% vs. 63%), vascular (29% vs. 17%) and cutaneous (22% vs. 7%) foci of infection, and Staphylococcus aureus aetiology (46% vs. 22%). Vegetations (84% vs. 72%), vascular phenomena (17% vs. 9%), splenomegaly (30% vs. 11%), and embolisation (41% vs 21%) were also more common. Surgical indication and surgery were less frequent in HIV-infected patients (54% vs 67%, 28% vs 47%, respectively). Median CD4 count in HIV-infected patients was 318 cells/mm3. In-hospital mortality (23% vs. 26%) and one-year mortality (25% vs. 32%) were similar in both groups. HIV infection was not independently associated with in-hospital (odds ratio 1·1, 95% CI 0·6-1·9) nor one-year mortality (hazard ratio 0·8, 95% CI 0·4-1·3). CONCLUSIONS: In the combined antiretroviral therapy era, less than 2% of IE patients have HIV infection. HIV-infected patients have a different clinical profile than those without HIV, but the presence of HIV does not seem to impact on IE prognosis.

ABSTRACT

Genetic minimal cut sets (gMCS) are genes that must be deactivated simultaneously to avoid unwanted states in a metabolic model. The concept of gMCS can be applied to two different scenarios. First, it can be used to identify potential gene toxicities in generic or healthy cell models. Second, it can be used to develop genetic strategies to target cancer cells and prevent their proliferation. Up to now, gMCS have been evaluated using the traditional procedure of preventing biomass production. This paper proposes an additional way: using essential metabolic tasks, which any human cell should perform, to enlarge the set of unwanted states. Including this addition can significantly improve the study of toxicities and reveal targets that can be used to treat unhealthy cells. Excluding metabolic tasks can cause important information to be overlooked, which could impact the study's success. Regarding toxicities, using the generic Human model, the number of detected generic toxicities with metabolic tasks increases from 106 to 281 (136 gMCSs of length 1 and 49 of length 2). We have used the following context-specific models to evaluate specific toxicities in different healthy tissues: blood, pancreas, liver, heart, and kidney. Again, considering metabolic tasks, we have found new toxicities (lengths 1 and 2) whose inactivation could damage these healthy tissues.Our research strategy has been applied to identify new cancer drug targets in two myeloma cell lines. We obtained new therapeutic targets of lengths 1 and 2 for each cell line. After analyzing the data, we conclude that incorporating metabolic tasks into cancer models can reveal important therapeutic targets previously disregarded by the conventional method of inhibiting biomass production. This approach also improves the evaluation of potential drug toxicities.

ABSTRACT

Background: Breast cancer (BC) is the most prevalent cancer diagnosis among women worldwide. Several randomized controlled trials and systematic reviews have shown the benefits of exercise before, during, and after cancer treatment to manage side effects related to cancer and its therapies. However, these are poorly implemented across the disease-span, specifically, during the preoperative setting. Methods: Patients diagnosed with BC and participating in a randomized controlled trial on the effects of a prehabilitation program based on Nordic walking, muscle strengthening, and therapeutic education were invited to participate in this qualitative substudy. Two groups of eight patients each were recorded, transcript and analyzed using a specialized software (Atlas-Ti®, version 24). Results: During the axial codification phase, 22 unique codes and 6 main themes were identified related to their experience with the program, namely, (1) information received prior to participating; (2) motivation to participate; (3) barriers; (4) facilitators; (5) perceived degree of support from healthcare workers as well as peers; and (6) satisfaction with the characteristics of the prehabilitation program. Conclusions: Patients interviewed showed great interest in prehabilitation as a way to prepare both physically and mentally for surgery. In order to implement these interventions, healthcare systems need to acknowledge barriers and facilitators as well as the need for these programs to be supervised and monitored to avoid adverse events.

ABSTRACT

BACKGROUND: The use of Smart Screening tools to identify mental health problems has scarce empirical data on their effectiveness. This study aims to explore the response rate of patients to this tool and observe their socio-demographic and healthcare characteristics, and the tool's ability to detect potential mental health diagnoses. METHODS: The study employed an online survey within patient portal from patients of four teaching hospitals in Madrid. The sample included 8749 patients, comprising 66.77 % females and 31.21 % middle-aged adults. RESULTS: 60.56 % responded to the Smart Screening tool. Respondents were found to be predominantly middle-aged women who had been contacted by mental health services multiple times but had not exhibited suicidal behaviour. These patients demonstrated a higher appointment attendance rate and generated low healthcare costs. The tool identified probable low depression and mild anxiety (72.16 %), and individuals aged 50-65 exhibited higher levels of mental health problems, such as psychosis and suicidality, although these results were not all significant regarding previous mental health diagnoses. LIMITATIONS: The Smart Screening tool collects anonymous online data through short questionnaires to apply sophisticated algorithms and determine probable mental health diagnoses. CONCLUSIONS: The response rate to the Smart Screening tool was higher than in previous studies. The respondents' profile was middle-aged and older women with moderate mental health problems, although suicidality was also identified. Future research should focus on those who did not respond to the tool and explore the link between previous psychiatric diagnoses and the accuracy of the Smart Screening tool.

ABSTRACT

Cardiogenic shock is characterized by tissue hypoperfusion due to the inadequate cardiac output to maintain the tissue oxygen demand. Despite some advances in cardiogenic shock management, extremely high mortality is still associated with this clinical syndrome. Its management is based on the immediate stabilization of hemodynamic parameters through medical care and the use of mechanical circulatory supports in specialized centers. This review aims to understand the cardiogenic shock current medical treatment, consisting mainly of inotropic drugs, vasopressors and coronary revascularization. In addition, we highlight the relevance of applying measures to other organ levels based on the optimization of mechanical ventilation and the appropriate initiation of renal replacement therapy.

ABSTRACT

Jump actions are common in several sports, and their performance is related to a myriad of biomechanical and physiological factors, with links to athletic performance and imbalances. Currently, a valid, field-based, easy-to-use tool to assess the quality of an explosive jump movement, similar to the required sports movements, is unavailable. Thus, the present study aimed to design and validate a field-based, easy-to-use tool that can be used to assess the quality of movement during an explosive single-leg countermovement jump (SL-CMJ). Ten experts participated in the content validation process for the checklist, including checking item relevance, definition accuracy, and scoring adequacy. Content validity was measured using the Aikens V format. The checklist included the items "Foot orientation," "Knee valgus/varus," "Internal/external hip flexed orientation," "Pelvis tilt," "Thorax tilt," "Thorax rotation," "Foot pronation/supination," "Asymmetrical hip," and "Lumbo-pelvic association". The items achieved a 0.60-0.99 in relevance, 0.70-1.00 in definition accuracy, and 0.80-0.83 in scoring adequacies in the Aikens V proof. The results from the context validation process suggest that the tool may be appropriate to assess athletes' quality of explosive movement. Furthermore, the results derived from such assessments may help to design better and safer training interventions.

ABSTRACT

We aimed to characterize the cognitive profile of post-acute COVID-19 syndrome (PACS) patients with cognitive complaints, exploring the influence of biological and psychological factors. Participants with confirmed SARS-CoV-2 infection and cognitive complaints ≥ 8 weeks post-acute phase were included. A comprehensive neuropsychological battery (NPS) and health questionnaires were administered at inclusion and at 1, 3 and 6 months. Blood samples were collected at each visit, MRI scan at baseline and at 6 months, and, optionally, cerebrospinal fluid. Cognitive features were analyzed in relation to clinical, neuroimaging, and biochemical markers at inclusion and follow-up. Forty-nine participants, with a mean time from symptom onset of 10.4 months, showed attention-executive function (69%) and verbal memory (39%) impairment. Apathy (64%), moderate-severe anxiety (57%), and severe fatigue (35%) were prevalent. Visual memory (8%) correlated with total gray matter (GM) and subcortical GM volume. Neuronal damage and inflammation markers were within normal limits. Over time, cognitive test scores, depression, apathy, anxiety scores, MRI indexes, and fluid biomarkers remained stable, although fewer participants (50% vs. 75.5%; p = 0.012) exhibited abnormal cognitive evaluations at follow-up. Altered attention/executive and verbal memory, common in PACS, persisted in most subjects without association with structural abnormalities, elevated cytokines, or neuronal damage markers.

ABSTRACT

There is growing evidence about how physical activity can improve cancer care. Unfortunately, exercise is still not widely prescribed to oncology patients, despite the benefit it brings. For this to occur, it is necessary for a multidisciplinary approach involving different types of healthcare professionals, given that each treatment be tailored for each single case. Besides incorporating appropriate infrastructures and referral pathways, we need to integrate exercise into healthcare practice, which ameliorates patients' quality of life and treatment side effects. From the Spanish Society of Medical Oncology (SEOM), and through the Exercise and Cancer Working Group, we indicate considerations, analyze patient care scenarios, and propose a referral pathway algorithm for exercise prescription, taking in account the patient's needs. In later sections of this paper, we describe how this algorithm could be implemented, and how the exercise programs should be built, including the physical activity contents, the settings, and the delivery mode. We conclude that professionals, infrastructures, and organizations should be available at every assistance level to create programs providing adequate exercise training for cancer patients.

ABSTRACT

BACKGROUND: The Six Minute Walk Test (6MWT) is a widely used measure of functional capacity in (p)rehabilitation of cancer patients, but it is time-consuming and requires specific space conditions. In this study we explore the association between the 6MWT with other measurements of physical functioning and their predictive value in classifying patients according to their estimated functional capacity. DESIGN: This prospective study included cancer patients referred to a prehabilitation programme prior to major surgery. For each patient, data on different measurements of physical functioning including the Duke Activity Status Index (DASI), the handgrip strength, the 30" Sit-to-Stand Test and self-reported physical activity levels were collected. Bivariate associations were performed to determine the association between the 6MWT and other variables. Multivariate analyses were performed to identify potential predictive factors of 6MWT in this population. A subsequent algorithm was developed to classify patients based on their functional capacity (good performance - 6MWT>400 m or poor performance 6MWT<400 m) RESULTS: Between mid-2018 to mid 2022, 692 patients were assessed of whom the 6MWT was performed in 524 (75.7 %) (mean age 72.5 ± 11.8 years; 57.1 % men). Moderate-to-strong correlations were found between 6MWT and 30" Sit-To-Stand Test (r = 0.54, p < 0.001), DASI (r = 0.68; p < 0.001) and handgrip strength (r = 0.5; p < 0.001). Multivariate analyses confirmed that a combination of six variables were able to classify 80 % of patients in good (>400 m) or poor (<400 m) performance in the 6MWT. CONCLUSION: The 6MWT was moderately associated with several variables of physical functioning, a combination of which can be used to predict performance in the 6MWT.

ABSTRACT

BACKGROUND: The evolving healthcare landscape necessitates highly qualified nurses equipped with a myriad of soft skills, including decision-making. Traditional teaching models have led to innovative, active methods that prioritise student participation and enhance crucial soft skill development, such as decision- making. Considering the recognised importance of improving clinical decision-making skills and the need for innovative training, a literature gap is present in assessing the effect of real world and game-based learning on decision-making abilities. OBJECTIVES: This study aimed to investigate the effect of real-world and game-based learning, specifically using case-based learning and escape room, on decision-making competence in postgraduate nursing students in academic and clinical settings. DESIGN: A descriptive, cross-sectional, quantitative intervention study was conducted, combining case-based learning and escape room methods sequentially. SETTINGS: The study was conducted among postgraduate nursing students at the University of Navarra in Spain. PARTICIPANTS: Sixty-six postgraduate nursing students, mostly women, participated in the study. METHODS: The study integrated case-based learning and escape room sequentially. Data were collected through an ad hoc online questionnaire, recorded escape times from the escape room, and academic scores. RESULTS: The study enrolled 66 participants with an average professional experience of 4.2 years. Academic results showed high scores in case resolution (average: 8.34) and knowledge tests (average: 9.21). Out of 11 groups, 81.8 % successfully escaped the escape room within 30 min, with positive questionnaire responses indicating enthusiasm, enjoyment and perceived effectiveness of the activities. CONCLUSIONS: Real-world and game-based learning significantly enhanced decision-making competence in postgraduate nursing students across academic and clinical settings, demonstrating the importance of diverse teaching methods. Further research, including comparative studies and longitudinal analyses, is needed to evaluate the educational benefits of integrating case-based learning and escape room methods in nurse education and to refine assessment tools while monitoring long-term student progress.

ABSTRACT

The Integrative Cluster subtypes (IntClusts) provide a framework for the classification of breast cancer tumors into 10 distinct groups based on copy number and gene expression, each with unique biological drivers of disease and clinical prognoses. Gene expression data is often lacking, and accurate classification of samples into IntClusts with copy number data alone is essential. Current classification methods achieve low accuracy when gene expression data are absent, warranting the development of new approaches to IntClust classification. Copy number data from 1980 breast cancer samples from METABRIC was used to train multiclass XGBoost machine learning algorithms (CopyClust). A piecewise constant fit was applied to the average copy number profile of each IntClust and unique breakpoints across the 10 profiles were identified and converted into ~ 500 genomic regions used as features for CopyClust. These models consisted of two approaches: a 10-class model with the final IntClust label predicted by a single multiclass model and a 6-class model with binary reclassification in which four pairs of IntClusts were combined for initial multiclass classification. Performance was validated on the TCGA dataset, with copy number data generated from both SNP arrays and WES platforms. CopyClust achieved 81% and 79% overall accuracy with the TCGA SNP and WES datasets, respectively, a nine-percentage point or greater improvement in overall IntClust subtype classification accuracy. CopyClust achieves a significant improvement over current methods in classification accuracy of IntClust subtypes for samples without available gene expression data and is an easily implementable algorithm for IntClust classification of breast cancer samples with copy number data.

ABSTRACT

The olive oil sector is a fundamental food in the Mediterranean diet. It has been demonstrated that the consumption of extra virgin olive oil (EVOO) with a high content of phenolic compounds is beneficial in the prevention and/or treatment of many diseases. The main objective of this work was to study the relationship between the content of phenolic compounds and the in vitro neuroprotective and anti-inflammatory activity of EVOOs from two PDOs in the province of Granada. To this purpose, the amounts of phenolic compounds were determined by liquid chromatography coupled to mass spectrometry (HPLC-MS) and the inhibitory activity of acetylcholinesterase (AChE) and cyclooxygenase-2 (COX-2) enzymes by spectrophotometric and fluorimetric assays. The main families identified were phenolic alcohols, secoiridoids, lignans, flavonoids, and phenolic acids. The EVOO samples with the highest total concentration of compounds and the highest inhibitory activity belonged to the Picual and Manzanillo varieties. Statistical analysis showed a positive correlation between identified compounds and AChE and COX-2 inhibitory activity, except for lignans. These results confirm EVOO's compounds possess neuroprotective potential.

ABSTRACT

Varietal volatile compounds are characteristic of each variety of grapes and come from the skins of the grapes. This work focuses on the development of a methodology for the analysis of free compounds in grapes from Trincadeira, Cabernet Sauvignon, Syrah, Castelão and Tinta Barroca from the 2021 and 2022 harvests, using HS-SPME-GC × GC-TOFMS. To achieve this purpose, a previous optimization step of sample preparation was implemented, with the optimized conditions being 4 g of grapes, 2 g of NaCl, and 2 mL of H2O. The extraction conditions were also optimized, and it was observed that performing the extraction for 40 min at 60 °C was the best for identifying more varietal compounds. The fiber used was a triple fiber of carboxen/divinylbenzene/polydimethylsiloxane (CAR/DVB/PDMS). In addition to the sample preparation, the analytical conditions were also optimized, enabling the adequate separation of analytes. Using the optimized methodology, it was possible to identify fifty-two free volatile compounds, including seventeen monoterpenes, twenty-eight sesquiterpenes, and seven C13-norisoprenoids. It was observed that in 2021, more free varietal volatile compounds were identifiable compared to 2022. According to the results obtained through a linear discriminant analysis (LDA), the differences in volatile varietal signature are observed both among different grape varieties and across different years.

ABSTRACT

BACKGROUND: Stroke is a common complication of infective endocarditis (IE). Our aim was to describe the prevalence and prognostic impact of stroke in a national cohort of IE. METHODS: Consecutive inclusion at 46 Spanish hospitals between 2008 and 2021. RESULTS: Out of 5667 IE cases, 1125 had acute stroke (19.8%): 818 ischemic strokes (811 cardioembolic strokes (193 with hemorrhagic transformation), 4 transient ischemic attacks, 3 lacunar infarctions), 127 intracranial hemorrhages, and 27 other neurological complications (cerebral abscesses, encephalitis, and meningitis). Compared to patients without stroke, those with stroke had a similar mean age (69 years) but were more frequently female (68.2% vs 63.7%, p = 0.04) and had a higher incidence of intracardiac complications (35% vs 30%, p = 0.01), surgical indication (69.9% vs 65.9%, p = 0.001), in-hospital mortality (40.9% vs 22.0%, p < 0.001), and 1-year mortality (46.2% vs 27.9%, p < 0.001). The following variables were independently associated with stroke: mitral location (odds ratio (OR) = 1.5, 95% confidence interval (CI) = 1.34-1.8, p < 0.001), vascular phenomenon (OR = 2.9, 95% CI = 2.4-3.6, p = 0.0001), acute renal failure (OR = 1.2, 95% CI = 1.0-1.4, p = 0.021), septic shock (OR = 1.3, 95% CI = 1.1-1.6, p = 0.007), sepsis (OR = 1.3, 95% CI = 1.1-1.6, p = 0.005), surgery indicated but not performed (OR = 1.4, 95% CI = 1.2-1.7, p < 0.001), community-acquired IE (OR = 1.2, 95% CI = 1-1.4, p = 0.017), and peripheral embolization (OR = 1.6, 95% CI = 1.4-1.9, p < 0.001). Stroke was an independent predictor of in-hospital (OR = 2.1, 95% CI = 1.78-2.51, p < 0.001) and 1-year mortality (hazard ratio = 1.9, 95% CI = 1.6-2.5). CONCLUSION: One-fifth of patients with IE have concomitant stroke. Stroke is associated with mortality.

MAIN VARIABLES OF INTEREST: Age, sex, comorbidity, functional dependence, treatment, complications, evolution, mortality. RESULTS: The most frequent reasons for admission were cardiac surgery and pneumonia. The average admission stay was significantly longer in patients under 85 years of age (p = 0,037). 84,3% of the latter benefited from invasive mechanical ventilation compared to 46,2% of older patients (p = <0,001). Patients over 85 years of age presented greater fragility. Admission for cardiac surgery was associated with a lower risk of mortality (HR = 0,18; 95% CI (0,062-0,527; p = 0,002). CONCLUSIONS: The results have shown an association between the reason for admission to the ICU and the risk of mortality in octogenarian patients. Cardiac surgery was associated with a better prognosis compared to medical pathology, where pneumonia was associated with a higher risk of mortality. Furthermore, a significant positive association was observed between age and frailty.

ABSTRACT

INTRODUCTION: Colorectal cancer (CRC) ranks as the second leading cause of cancer-related deaths. The PREHAB trial revealed that prehabilitation in colorectal surgery leads to a reduction of severe complications and enhanced functional capacity. Nevertheless, risk selection for prehabilitation and the potential benefits for patients without postoperative complications remains unclear. This study aims to assess postoperative functional capacity, also in patients without postoperative complications. MATERIALS & METHODS: This study was a secondary analysis of the PREHAB trial. Functional capacity tests, including cardiopulmonary exercise testing (CPET), steep ramp test (SRT), 6-min walking test (6MWT), stair climb test (SCT), 30" sit-to-stand test (STS), timed-up-and-go test (TUG), and muscle strength assessments, were conducted at baseline (T0) and 4 weeks postoperatively (T3). The primary outcome was the relative change in functional capacity from baseline to postoperative (ΔT0-T3) per group (i.e., prehabilitation vs control). Secondary, identical analysis were performed for patients without postoperative complications in each group. RESULTS: Intention-to-treat analysis included 251 patients. For postoperative functional capacity, prehabilitation patients showed improvements in VO2peak (p = 0.024), VO2AT (p = 0.017), SRT (p = 0.001), 6MWT (p = 0.049), SCT (p = 0.012), and STS (p = 0.001) compared to the control group. Regarding muscle strength, prehabilitation patients showed improvements in estimated 1RM lateral pull down (p = 0.016), 1RM chest press (p = 0.001), 1RM leg press (p = 0.001) and HGS (p = 0.005) compared to controls. Additionally, prehabilitation patients more often reached baseline levels at T3 in VO2AT (p = 0.037), SRT (p = 0.008), 6MWT (p = 0.013), STS (p = 0.012), estimated 1RM lateral pull down (p = 0.002), 1RM chest press (p = 0.001) and 1RM leg press (p = 0.001) compared to controls. Moreover, even patients without postoperative complications in the prehabilitation group showed better postoperative functional capacity and more often reached baseline levels at T3, compared to controls. CONCLUSION: Multimodal prehabilitation in CRC surgery is associated with improved postoperative functional capacity, even in patients without postoperative complications.

ABSTRACT

Background: Several aspects of the occurrence and management of mycotic aneurysm (MA) in patients with infective endocarditis (IE) have not been studied. Objectives: To determine the incidence and factors associated with MA presence and rupture and to assess the evolution of those initially unruptured MA. Methods: Prospective multicenter cohort including all patients with definite IE between January 2008 and December 2020. Results: Of 4548 IE cases, 85 (1.9%) developed MA. Forty-six (54.1%) had intracranial MA and 39 (45.9%) extracranial MA. Rupture of MA occurred in 39 patients (45.9%). Patients with ruptured MA had higher 1-year mortality (hazard ratio, 2.33; 95% confidence interval, 1.49-3.67). Of the 55 patients with initially unruptured MA, 9 (16.4%) presented rupture after a median of 3 days (interquartile range, 1-7) after diagnosis, being more frequent in intracranial MA (32% vs 3.3%, P = .004). Of patients with initially unruptured MA, there was a trend toward better outcomes among those who received early specific intervention, including lower follow-up rupture (7.1% vs 25.0%, P = .170), higher rate of aneurysm resolution in control imaging (66.7% vs 31.3%, P = .087), lower MA-related mortality (7.1% vs 16.7%, P = .232), and lower MA-related sequalae (0% vs 27.8%, P = .045). Conclusions: MA occurred in 2% of the patients with IE. Half of the Mas occurred in an intracranial location. Their rupture is frequent and associated with poor prognosis. A significant proportion of initially unruptured aneurysms result from rupture during the first several days, being more common in intracranial aneurysms. Early specific treatment could potentially lead to better outcomes.
