Real world effectiveness and safety of nivolumab in patients with relapsed or refractory classical hodgkin lymphoma. / Efectividad y seguridad en vida real de nivolumab en pacientes con linfoma de hodgkin clásico en recaída o refractario.

OBJECTIVE: The primary objective is to describe the real-life effectiveness and safety of nivolumab treatment in patients with relapsed or refractory classical Hodgkin's lymphoma. The secondary objective is to describe the therapeutic management after nivolumab monotherapy. METHOD: Observational, retrospective, multidisciplinary study including all patients with relapsed or refractory classical Hodgkin's lymphoma treated with nivolumab monotherapy from November 2015 to March 2023. Patient and treatment-related variables were collected. Effectiveness was measured as overall response rate, progression-free survival and overall survival. Safety was measured as percentage of patients with adverse effects and severity. RESULTS: Thirteen patients were included, median age 37.5 years (RIQ: 25.3-54.7), 84.6% male. The median number of previous lines of therapy was 3 (RIQ: 2.0-4.5), including autologous hematopoietic stem cell transplantation (84.6%) and brentuximab vedotin (100%). All received nivolumab 3 mg/kg/14 days, with a median of 11 cycles (RIQ: 6.5-20.5) per patient. Median time on treatment was 4.9 months (RIQ: 3.0-9.6) and median follow-up time was 9.2 months (RIQ: 5.6-32.3). Complete response was achieved by 3 patients (23.1%), partial response by 3 (23.1%), stable disease by 3 (23.1%) and progression by 4 (30.8%). The objective response rate was 46.2%. Median progression-free survival was 23.9 months (95%CI: 0-49.1), median overall survival was not reached. At the study cutoff date, five patients had died (38.5%), four were in complete remission without active treatment (30.8%) and four were continuing treatment (30.8%). Adverse events occurred in 76.9% of patients, 44% of severity ≥3, the most frequent being hypothyroidism and hepatotoxicity. One patient discontinued treatment due to pneumonitis, two suffered treatment delays (thrombocytopenia and hypertransaminemia) and one changed the regimen to monthly (pulmonary toxicity). CONCLUSIONS: Nivolumab in the treatment of relapsed or refractory classical Hodgkin's lymphoma has confirmed in the study sample favorable effectiveness data, expressed as objective response rate of 46.2% and clinical benefit of 69.2%. Safety was acceptable, manageable, and consistent with that described in the literature.

The Polyanalgesic Consensus Conference (PACC)®: Intrathecal Drug Delivery Guidance on Safety and Therapy Optimization When Treating Chronic Noncancer Pain.

INTRODUCTION: The International Neuromodulation Society convened a multispecialty group of physicians and scientists based on expertise with international representation to establish evidence-based guidance on intrathecal drug delivery in treating chronic pain. This Polyanalgesic Consensus Conference (PACC)® project, created more than two decades ago, intends to provide evidence-based guidance for important safety and efficacy issues surrounding intrathecal drug delivery and its impact on the practice of neuromodulation. MATERIALS AND METHODS: Authors were chosen on the basis of their clinical expertise, familiarity with the peer-reviewed literature, research productivity, and contributions to the neuromodulation literature. Section leaders supervised literature searches of MEDLINE, BioMed Central, Current Contents Connect, Embase, International Pharmaceutical Abstracts, Web of Science, Google Scholar, and PubMed from 2017 (when PACC® last published guidelines) to the present. Identified studies were graded using the United States Preventive Services Task Force criteria for evidence and certainty of net benefit. Recommendations are based on the strength of evidence or consensus when evidence is scant. RESULTS: The PACC® examined the published literature and established evidence- and consensus-based recommendations to guide best practices. Additional guidance will occur as new evidence is developed in future iterations of this process. CONCLUSIONS: The PACC® recommends best practices regarding intrathecal drug delivery to improve safety and efficacy. The evidence- and consensus-based recommendations should be used as a guide to assist decision-making when clinically appropriate.

Onasemnogene Abeparvovec Administration via Peripherally Inserted Central Catheter: A Case Report.

Onasemnogene abeparvovec (OA) is the approved intravenous gene therapy for the treatment of spinal muscular atrophy (SMA). A functional copy of the human SMN1 gene was inserted into the target motor neuron cells via a viral vector, AAV9. In clinical trials, OA was infused through a peripheral venous catheter, and no data are available on central catheter use. Recently, we had a case where OA was administered directly into the right atrium via a peripherally inserted central catheter (PICC) instead of a peripheral line, as recommended. The patient was a female child aged 4 months, diagnosed as SMA type I. For practical reasons, a dose of OA according to the weight of the patient (1.1 × 1014 vectorial genomes/kg) was administered via PICC in 1 h, as the product information recommends. The drug was well tolerated, with no hypersensitivity reactions or initial elevation of transaminases or other adverse effects. To our knowledge, this is the first case reported where OA was administered via a central line. This type of administration is not contraindicated, but it is not specifically contemplated or recommended. It is unknown whether central line administration could have any implications for transduction efficiency and immunogenicity. Future studies should clarify these aspects, as each gene therapy has a specific optimal dose recorded that depends on the site and route of administration of the drug, the AAV variant and the transgene.

Durable response after tisagenlecleucel in adults with relapsed/refractory follicular lymphoma: ELARA trial update.

ABSTRACT: Tisagenlecleucel is approved for adults with relapsed/refractory (r/r) follicular lymphoma (FL) in the third- or later-line setting. The primary analysis (median follow-up, 17 months) of the phase 2 ELARA trial reported high response rates and excellent safety profile in patients with extensively pretreated r/r FL. Here, we report longer-term efficacy, safety, pharmacokinetic, and exploratory biomarker analyses after median follow-up of 29 months (interquartile range, 22.2-37.7). As of 29 March 2022, 97 patients with r/r FL (grades 1-3A) received tisagenlecleucel infusion (0.6 × 108-6 × 108 chimeric antigen receptor-positive viable T cells). Bridging chemotherapy was allowed. Baseline clinical factors, tumor microenvironment, blood soluble factors, and circulating blood cells were correlated with clinical response. Cellular kinetics were assessed by quantitative polymerase chain reaction. Median progression-free survival (PFS), duration of response (DOR), and overall survival (OS) were not reached. Estimated 24-month PFS, DOR, and OS rates in all patients were 57.4% (95% confidence interval [CI], 46.2-67), 66.4% (95% CI, 54.3-76), and 87.7% (95% CI, 78.3-93.2), respectively. Complete response rate and overall response rate were 68.1% (95% CI, 57.7-77.3) and 86.2% (95% CI, 77.5-92.4), respectively. No new safety signals or treatment-related deaths were reported. Low levels of tumor-infiltrating LAG3+CD3+ exhausted T cells and higher baseline levels of naïve CD8+ T cells were associated with improved outcomes. Tisagenlecleucel continued to demonstrate highly durable efficacy and a favorable safety profile in this extended follow-up of 29 months in patients with r/r FL enrolled in ELARA. This trial was registered at www.clinicaltrials.gov as #NCT03568461.

Enantioselective Amination of 4-Substituted Pyrazolones Catalyzed by Oxindole-Containing Thioureas and by a Recyclable Linear-Polymer-Supported Analogue in a Continuous Flow Process.

A highly efficient organocatalytic amination of 4-substituted pyrazolones with azodicarboxylates mediated by a novel quinine-derived thiourea with a 3,3-diaryl-oxindole scaffold is reported. This synthetic method furnished 4-amino-5-pyrazolones in high yields and with excellent enantioselectivities (up to 97:3 er) at room temperature in short reaction times. Moreover, a linear-polymer-supported bifunctional thiourea, synthesized by reacting a bifunctional aromatic monomer (biphenyl) with isatin in superacidic media and further derivatization, was proven to be also an efficient heterogeneous organocatalyst for this α-amination reaction. The practical value of this process was demonstrated by the use of the immobilized catalyst in recycling experiments, maintaining the activity without additional reactivation, and in flow processes, allowing the synthesis of 4-amino-pyrazolone derivatives in a gram scale with high yield and enantioselectivity.

Primary central nervous system marginal zone lymphoma.

Marginal zone lymphoma (MZL) is the most common indolent lymphoma primarily arising in the central nervous system (CNS). To date, 207 cases of primary CNS MZL (PCNSMZL) were published, mostly as single case reports or small case series. It most commonly presents as extra-axial dural-based masses, more frequently in middle-aged women, displaying an insidious onset, with a long history of symptoms preceding the diagnosis. PCNSMZL can be radiographically mistaken for meningioma. PCNSMZL consists of CD20+ , CD3- small B lymphocytes with varying degrees of plasmacytic differentiation and low proliferation index. Trisomy 3, but not MALT1 or IgH translocation, is a common genetic abnormality. Other recurrent genetic abnormalities involve TNFAIP3 and NOTCH2. Ethiopathogenesis was poorly investigated. Due to its rarity, standard of care remains to be defined; it exhibits an excellent prognosis after varied treatments, such as surgery, radiotherapy, chemotherapy or their combinations. Nevertheless, each treatment should be considered after an accurate analysis of overtreatment risk. Short follow-up is a major limitation in reported PCNSMZL cases, which restrains our knowledge on long-term results and iatrogenic sequels. This review was focussed on presentation, differential diagnoses, pathological findings, treatment options and clinical outcomes of PCNSMZL; recommendations for best clinical practice are provided.

Sobrevida del cáncer glótico en estadio inicial en 4 centros hospitalarios de Uruguay / Survival of glottic cancer in the initial stage in 4 hospital centers in Uruguay / Sobrevivência de câncer glótico em estágio inicial em 4 hospitais uruguaios

Introducción: El cáncer de laringe es el tumor maligno de mayor prevalencia en la Otorrinolaringología. La topografía glótica es la más frecuente en Uruguay y suele detectarse en estadios tempranos dada la manifestación precoz y sostenida de disfonía. El objetivo de este estudio es describir la sobrevida libre de enfermedad (SLE) y la sobrevida global (SG) de los pacientes con cáncer de laringe glótico en estadio T1N0M0 en 4 instituciones de Montevideo. Metodología: Se analizó de forma retrospectiva la SG y SLE de 55 pacientes diagnosticados con cáncer de glotis T1 entre los años 2009 y 2019. Para el cálculo de la sobrevida se utilizó el método de Kaplan-Meier. Se estudió además el efecto de variables pronósticas de interés sobre la SG mediante análisis univariado y multivariado. Resultados: En la muestra analizada la SG de los pacientes con cáncer glótico T1N0M0 fue como media de 7.706 años (IC 95% 6.63 - 8.78). A los 5 años, la SG fue de 77.5% (± 7%) y de 62% (± 9.8%) a los 10 años. La SLE para todos los pacientes correspondió al 74.6% (± 7.5%) y 63.1% (± 9.8%), a 5 y 10 años respectivamente. No se alcanzaron las medianas de SG ni de SLE para los grupos. Conclusiones: Los valores de SG y SLE medios obtenidos en nuestro medio son comparables a los valores reportados en la bibliografía internacional. No se alcanzó la mediana de SG ni de SLE, por lo que se puede afirmar que ésta enfermedad tiene, cuando se realiza el tratamiento adecuado, un buen pronóstico vital a los 10 años. Se requiere un seguimiento más largo para determinar las medianas de SG y SLE de los grupos en estudio.

Introduction: Laryngeal cancer is the most prevalent malignant tumor in Otorhinolaryngology. Glottic topography is the most frequent in Uruguay and is usually detected in early stages given the early and sustained manifestation of dysphonia. The objective of this study is to analyze disease-free survival (DFS) and overall survival (OS) of patients with stage T1N0M0 glottic laryngeal cancer at 4 institutions in Montevideo. Methodology: The mean OS and DFS of 55 patients diagnosed with T1 glottic cancer between 2009 and 2019 were retrospectively analyzed. Kaplan-Meier method was used to calculate survival. The prognostic effect of certain variables of interest on OS was also studied using univariate and multivariate analysis. Results: In this study, mean odds survival (OS) for T1N0M0 glottic cancer was 7.706 years (CI 95% 6.63 - 8.78). At 5 years, OS was 77.5% (± 7%) and at 10 years was 62% (± 9.8%). Disease free survival (DFS) was 74.6% ± (7.5%) at 5 years and 63.1% (± 9.8%), at 10 years. Median OS and DFS for the groups were not reached. Conclusions: OS and DFS in our medium is comparable to that reported in the international literature. The median OS and DFS were not reached, so it can be stated that this disease has, when appropriate treatment is performed, a good vital prognosis at 10 years. Longer follow-up is required to determine the median OS and DFS of the study groups.

Objective The objectives are to know the opinion of neurologists and hospital pharmacists on those aspects still under debate regarding the role of anti-CGRP monoclonal antibodies in the preventive treatment of migraine. To identify those controversies that still exist. To propose agreed recommendations for improvement of care. And to promote access of clinicians and patients to these new treatments in the prevention of migraine with biological drugs, in order to improve patient care and follow-up. Methodology Recommendations for the use of biological drugs in the prevention of migraine were identified and evaluated through the Delphi consensus methodology, proposing 88 statements grouped into three themes: a clinical module that deals with the management of biological treatments in migraine; a patient module that discusses patient education and adherence improvement strategies; and a coordination module that includes statements related to strategies to improve joint work between the two groups. The 9-point Likert ordinal scale was used to score these recommendations and, subsequently, the data was statistically analyzed through different metrics. Results After both rounds of voting, consensus was reached in agreement on 71 of the 88 statements (80.7%), leaving one statement (1.1%) with consensus in disagreement and 16 remaining as indeterminate (18.2%). Conclusions The high degree of consensus indicates that the opinion of neurologists and hospital pharmacists on the role of anti-CGRP monoclonal antibodies in the treatment of migraine is very similar and allows identifying those controversies that still exist, to improve the care and follow-up of patients with migraine.

Environmental DNA reveals the genetic diversity and population structure of an invasive species in the Laurentian Great Lakes.

Environmental DNA (eDNA) has been established as a noninvasive and efficient approach to sample genetic material from aquatic environments. Although most commonly used to determine species presence and measure biodiversity, eDNA approaches also hold great potential to obtain population-level genetic information from water samples. In this study, we sequenced a panel of multiallelic microsatellite markers from filtered water and fish tissue samples to uncover patterns of intraspecific diversity in the freshwater Round Goby (Neogobius melanostomus) across their invaded range in the Laurentian Great Lakes region. Although we found that the concentration of nuclear eDNA is lower than mitochondrial eDNA, we nonetheless detected over two-thirds of all nuclear alleles identified from genotyped tissues in our eDNA samples, with the greatest recovery of common alleles in the population. Estimates of allele frequencies and genetic variability within and between populations were detected from eDNA in patterns that were consistent with individual tissue-based estimates of genetic diversity and differentiation. The strongest genetic differentiation in both eDNA and tissues exists in an isolation by distance pattern. Our study demonstrates the potential for eDNA-based approaches to characterize key population parameters required to effectively monitor, manage, or sustain aquatic species.

Omics-Based Approaches for the Characterization of Pompe Disease Metabolic Phenotypes.

Lysosomal storage disorders (LSDs) constitute a large group of rare, multisystemic, inherited disorders of metabolism, characterized by defects in lysosomal enzymes, accessory proteins, membrane transporters or trafficking proteins. Pompe disease (PD) is produced by mutations in the acid alpha-glucosidase (GAA) lysosomal enzyme. This enzymatic deficiency leads to the aberrant accumulation of glycogen in the lysosome. The onset of symptoms, including a variety of neurological and multiple-organ pathologies, can range from birth to adulthood, and disease severity can vary between individuals. Although very significant advances related to the development of new treatments, and also to the improvement of newborn screening programs and tools for a more accurate diagnosis and follow-up of patients, have occurred over recent years, there exists an unmet need for further understanding the molecular mechanisms underlying the progression of the disease. Also, the reason why currently available treatments lose effectiveness over time in some patients is not completely understood. In this scenario, characterization of the metabolic phenotype is a valuable approach to gain insights into the global impact of lysosomal dysfunction, and its potential correlation with clinical progression and response to therapies. These approaches represent a discovery tool for investigating disease-induced modifications in the complete metabolic profile, including large numbers of metabolites that are simultaneously analyzed, enabling the identification of novel potential biomarkers associated with these conditions. This review aims to highlight the most relevant findings of recently published omics-based studies with a particular focus on describing the clinical potential of the specific metabolic phenotypes associated to different subgroups of PD patients.

Big Four LinkedIn Dimensions: Signals of Soft Skills? / [¿Son señales de soft skills las dimensiones del modelo LinkedIn Big Four?]

The use of LinkedIn as a tool in the recruitment and selection process has become routine in human resource management. However, a major drawback of such an approach is the lack of systematic and rigorous inferences on the psychological characteristics of the candidates. Calls have been made by scholars for further research on the psychometric guarantee of LinkedIn as a tool in the selection process. This study adopts signalling theory as a framework for exploring how LinkedIn profile information signals a candidate’s soft skills. Using a sample of 169 ITC professionals, through a cross-sectional design, soft skills were measured by means of a self-report questionnaire and LinkedIn profiles were assessed using rubrics for measuring the LinkedIn Big Four. Our findings demonstrate that LinkedIn Big Four Breadth of Professional Experience and Social Capital are valid signals of leadership, communication, problem solving, entrepreneurial and commercial thinking, planning and organization, and teamwork. We discuss the practical and theoretical implications of our results.(AU)

El uso de LinkedIn como herramienta en el proceso de reclutamiento y selección se ha convertido en algo habitual en la gestión de recursos humanos. Sin embargo, se carece de información rigurosa sobre la calidad de las inferencias que realizan los evaluadores sobre las características psicológicas de los candidatos, por lo que es necesario realizar más investigación sobre las garantías psicométricas de LinkedIn como herramienta de selección de personal. En consecuencia, el presente estudio adopta la teoría de las señales como marco para explorar cómo la información del perfil de LinkedIn es un indicador válido de las soft skills de los candidatos. Utilizando una muestra de 169 profesionales del sector tecnológico en España, mediante un diseño transversal, se midieron estas “habilidades blandas” a través de un cuestionario, mientras que los perfiles de LinkedIn se evaluaron utilizando las rúbricas del modelo LinkedIn Big Four. Los resultados muestran que las dimensiones del LinkedIn Big Four referentes a la experiencia profesional y el capital social, son señales válidas de las siguientes soft skills: liderazgo, comunicación, resolución de problemas, intraemprendimiento, pensamiento comercial, planificación y organización y trabajo en equipo.

Effect of Conventional Spinal Cord Stimulation on Serum Protein Profile in Patients With Persistent Spinal Pain Syndrome: A Case-Control Study.

BACKGROUND: Spinal cord stimulation (SCS) provides pain relief for most patients with persistent spinal pain syndrome type 2 (PSPS 2). Evidence is mounting on molecular changes induced by SCS as one of the mechanisms to explain pain improvement. We report the SCS effect on serum protein expression in vivo in patients with PSPS 2. MATERIALS AND METHODS: Serum proteins were identified and quantified using mass spectrometry. Proteins with significantly different expression among patients with PSPS 2 relative to controls, responders, and nonresponders to SCS, or significantly modulated by SCS relative to baseline, were identified. Those most correlated with the presence and time course of pain were selected using multivariate discriminant analysis. Bioinformatic tools were used to identify related biological processes. RESULTS: Thirty patients with PSPS 2, of whom 23 responded to SCS, were evaluated, together with 14 controls with no pain who also had undergone lumbar spinal surgery. A significant improvement in pain intensity, disability, and quality of life was recorded among responders. Five proteins differed significantly at baseline between patients with PSPS 2 and controls, with three proteins, mostly involved in immune processes and inflammation, being downregulated and two, mostly involved in vitamin metabolism, synaptic transmission, and restorative processes, being upregulated. In addition, four proteins, mostly related to immune processes and inflammation, decreased significantly, and three, mostly related to iron metabolism and containment of synaptic sprouting, increased significantly during SCS. CONCLUSION: This study identifies various biological processes that may underlie PSPS 2 pain and SCS therapeutic effects, including the modulation of neuroimmune response and inflammation, synaptic sprouting, vitamin and iron metabolism, and restorative processes.

Peri-operative Hemi-diaphragmatic Variations After Brachial Plexus Block Above the Clavicle: A Prospective Observational Study of the Contralateral Side.

OBJECTIVE: Hemi-diaphragm palsy after brachial plexus block above the clavicle (BPBAC) occurs frequently, but few patients develop post-operative pulmonary complications (PPC). We hypothesized that contralateral hemidiaphragm function increases after BPBAC. This contralateral function preserves global diaphragmatic function, avoiding PPC in the case of ipsilateral hemi-diaphragm palsy. METHODS: This prospective observational cohort study included 64 adult patients undergoing shoulder surgery with planned BPBAC (interscalene brachial plexus block and supraclavicular block). The Thickening Fraction (TF) was measured by ultrasound in both hemi-diaphragms, ipsilateral (TF ipsilateral) and contralateral (TFcontralateral) to the BPBAC, before and after the surgery. TFglobal is the sum of TFipsilateral and TFcontralateral. PPC were defined as occurrences of dyspnea, tachypnea, SpO2 <90% or SpO2/FiO2 <315. RESULTS: TFcontralateral increased significantly (an average of 40%) after BPBAC (p = 0.001), and TFipsilateral decreased (an average of 72%). After BPBAC, 86% of patients had a decreased TFipsilateral and 59% of patients an increased TFcontralateral at post-operatively. Only 17% of patients have PPC. CONCLUSION: After BPBAC, global diaphragm function decreases because of ipsilateral hemi-diaphragm reduction, but less than expected because of increased contralateral hemi-diaphragm function. As a part of diaphragm function, contralateral hemi-diaphragm function must be checked.
