RESUMEN

Diffuse large B-cell lymphoma (DLBCL) patients with relapsed or refractory (RR) disease have poor outcomes with current salvage regimens. We conducted a phase 2 trial to analyse the safety and efficacy of adding lenalidomide to R-ESHAP (LR-ESHAP) in patients with RR DLBCL. Subjects received 3 cycles of lenalidomide 10 mg/day on days 1-14 of every 21-day cycle, in combination with R-ESHAP at standard doses. Responding patients underwent autologous stem-cell transplantation (ASCT). The primary endpoint was the overall response rate (ORR) after 3 cycles. Centralized cell-of-origin (COO) classification was performed. Forty-six patients were included. The ORR after LR-ESHAP was 67% (35% of patients achieved complete remission). Patients with primary refractory disease (n = 26) had significantly worse ORR than patients with non-refractory disease (54% vs. 85%, p = 0.031). No differences in response rates according to the COO were observed. Twenty-eight patients (61%) underwent ASCT. At a median follow-up of 41 months, the estimated 3-year PFS and OS were 42% and 48%, respectively. The most common grade ≥3 adverse events were thrombocytopenia (70% of patients), neutropenia (67%) and anaemia (35%). There were no treatment-related deaths during LR-ESHAP cycles. In conclusion, LR-ESHAP is a feasible salvage regimen with promising efficacy results for patients with RR DLBCL.

RESUMEN

BACKGROUND: Poly(ADP-ribose) polymerase (PARP) inhibitor maintenance therapy is the standard of care for some patients with advanced ovarian cancer. We evaluated the efficacy and safety of PARP inhibitor rechallenge. PATIENTS AND METHODS: This randomized, double-blind, multicenter trial (NCT03106987) enrolled patients with platinum-sensitive relapsed ovarian cancer who had received one prior PARP inhibitor therapy for ≥18 and ≥12 months in the BRCA-mutated and non-BRCA-mutated cohorts, respectively, following first-line chemotherapy or for ≥12 and ≥6 months, respectively, following a second or subsequent line of chemotherapy. Patients were in response following their last platinum-based chemotherapy regimen and were randomized 2 : 1 to maintenance olaparib tablets 300 mg twice daily or placebo. Investigator-assessed progression-free survival (PFS) was the primary endpoint. RESULTS: Seventy four patients in the BRCA-mutated cohort were randomized to olaparib and 38 to placebo, and 72 patients in the non-BRCA-mutated cohort were randomized to olaparib and 36 to placebo; >85% of patients in both cohorts had received ≥3 prior lines of chemotherapy. In the BRCA-mutated cohort, the median PFS was 4.3 months with olaparib versus 2.8 months with placebo [hazard ratio (HR) 0.57; 95% confidence interval (CI) 0.37-0.87; P = 0.022]; 1-year PFS rates were 19% versus 0% (Kaplan-Meier estimates). In the non-BRCA-mutated cohort, median PFS was 5.3 months for olaparib versus 2.8 months for placebo (HR 0.43; 95% CI 0.26-0.71; P = 0.0023); 1-year PFS rates were 14% versus 0% (Kaplan-Meier estimates). No new safety signals were identified with olaparib rechallenge. CONCLUSIONS: In ovarian cancer patients previously treated with one prior PARP inhibitor and at least two lines of platinum-based chemotherapy, maintenance olaparib rechallenge provided a statistically significant, albeit modest, PFS improvement over placebo in both the BRCA-mutated and non-BRCA-mutated cohorts, with a proportion of patients in the maintenance olaparib rechallenge arm of both cohorts remaining progression free at 1 year.

RESUMEN

Alveolar soft part sarcoma (ASPS) accounts for less than 1 % of all soft tissue sarcomas. ASPS presents a poor prognosis and develops frequent metastases, especially in the lungs, brain and bones. Current therapies, such as surgery, radiotherapy and chemotherapy, are not fully effective and other alternative treatments are currently being studied. ASPS is predominantly found in the deep soft tissues of the lower extremities. To our knowledge, only thirteen primary intraosseous ASPS have been reported in the literature. In this study, we report two new cases of this exceedingly rare entity. Both cases already had multiple metastases since diagnosis; one of them represents the first case of a primary bone ASPS in the ulna and is also the primary intraosseous ASPS with the longest reported case of survival, after having maintained long periods of stabilization despite not having received any systemic treatment.

RESUMEN

Cancers develop by sustained growth, migration and invasion properties of tumour cells, supported by complex interactions with stromal cells within the tumour micro-environment. This review is focused on the latest discoveries regarding the highlighted role of angiogenesis and tumour micro-environment in ovarian cancer. This cancer milieu encompasses non-cancerous cells present in the tumour or nearby, including vessel-forming cells, fibroblasts and immune cells amongst others that work in a cooperative way with cancer cells, impacting tumour behaviour. Angiogenesis, migration and invasion, and more recently immune evasion, are cancer hallmarks clearly dependent on these supporting cells. Moreover, these stromal cells are more genetically stable than tumour cells and thus represent an attractive therapeutic target. A better understanding of the stromal cells function, and their complex interplay with cancer cells, will open additional areas to target, as the tumour-host interface.

RESUMEN

Background: Niraparib is a poly(ADP-ribose) polymerase inhibitor approved in the USA and Europe for maintenance treatment of adult patients with recurrent epithelial ovarian, fallopian tube, or primary peritoneal cancer who are in complete or partial response to platinum-based chemotherapy. In the pivotal ENGOT-OV16/NOVA trial, the dose reduction rate due to treatment-emergent adverse event (TEAE) was 68.9%, and the discontinuation rate due to TEAE was 14.7%, including 3.3% due to thrombocytopenia. A retrospective analysis was carried out to identify clinical parameters that predict dose reductions. Patients and methods: All analyses were carried out on the safety population, comprising all patients who received at least one dose of study drug. Patients were analyzed according to the study drug consumed (i.e., as treated). A predictive modeling method (decision trees) was used to identify important variables for predicting the likelihood of developing grade ≥3 thrombocytopenia within 30 days after the first dose of niraparib and determine cut-off points for chosen variables. Results: Following dose modification, 200 mg was the most commonly administered dose in the ENGOT-OV16/NOVA trial. Baseline platelet count and baseline body weight were identified as risk factors for increased incidence of grade ≥3 thrombocytopenia. Patients with a baseline body weight <77 kg or a baseline platelet count <150 000/µl in effect received an average daily dose ∼200 mg (median = 207 mg) due to dose interruption and reduction. Progression-free survival in patients who were dose reduced to either 200 or 100 mg was consistent with that of patients who remained at the 300 mg starting dose. Conclusions: The analysis presented suggests that patients with baseline body weight of <77 kg or baseline platelets of <150 000/µl may benefit from a starting dose of 200 mg/day.

RESUMEN

The recently discovered pure-quartic solitons, arising from the interaction of quartic dispersion and Kerr nonlinearity, open the door to unexplored soliton regimes and ultrafast laser science. Here, we report a general analysis of the dispersion and nonlinear properties necessary to observe pure-quartic solitons in optical platforms. We apply this analysis, in combination with numerical calculations, to the design of pure-quartic soliton supporting microstructured optical fibers. The designs presented here, which have realistic fabrication tolerances, support unperturbed pure-quartic soliton propagation providing access to an unmatched platform to study novel soliton physics.

RESUMEN

We present a 86-year-old woman without relevant medical history and two brothers who died by dementia, who started at 55 years with depression and personality changes with ongoing worsening (>30 years) and functional decline. Screening dementia blood test and brain magnetic resonance imaging did not show results that pointed to a secondary cause. The patient met the diagnostic criteria for possible behavioral frontotemporal dementia with a slow progression (bvFTD-SP), suggesting a benign variant. A genetic study confirmed a C9ORF72 hexanucleotide expansion, making this the sixth case mentioned in the literature. We review and discuss the other cases described previously.

RESUMEN

Semantic variant primary progressive aphasia (svPPA) is a clinical syndrome included in the frontotemporal dementia (FTD) spectrum. Unlike other forms of FTD, it is sporadic in the majority of cases and not commonly associated with motor neuron disease (MND). We describe a case of svPPA associated with MND in the same family, due to a mutation of the transactive response DNA binding protein (TARDBP) gene, and review the literature.

RESUMEN

The consensus statements regarding first-line therapies in women with ovarian cancer, reached at the Fifth Ovarian Cancer Consensus Conference held in Tokyo, Japan, in November 2015 are reported. Three topics were reviewed and the following statements are recommended: (i) Surgery: the subgroups that should be considered in first-line ovarian cancer clinical trials should be (a) patients undergoing primary debulking surgery and (b) patients receiving neo-adjuvant chemotherapy. The amount of residual disease following surgery should further stratify patients into those with absent gross residual disease and others. (ii) Control arms for chemotherapy: for advanced stage ovarian cancer the standard is intravenous 3-weekly carboplatin and paclitaxel. Acceptable alternatives, which should be stratified variables in trials when more than one regimen is offered, include weekly paclitaxel plus 3-weekly carboplatin, the addition of bevacizumab to 3-weekly carboplatin and paclitaxel, and intraperitoneal therapy. (iii) Trial Endpoints: overall survival is the preferred primary endpoint for first-line clinical trials with or without a maintenance component. Progression-free survival (PFS) is an alternative primary endpoint, but if PFS is chosen overall survival must be measured as a secondary endpoint and PFS must be supported by additional endpoints, including predefined patient reported outcomes and time to first or second subsequent therapy. For neoadjuvant therapy, additional 'window of opportunity' endpoints should be included.

RESUMEN

BACKGROUND: Patients with relapsed unresectable osteosarcoma represents an unmet need, so active and safe systemic treatments are required. Fas cell surface death receptor and mammalian target of rapamycin pathways are implicated in progressing osteosarcoma, and we had preclinical and clinical experience with a scheme that targets both pathways. Therefore, we designed a phase II trial with gemcitabine plus rapamycin, to determine the efficacy and safety, in this subset of patients. PATIENTS AND METHODS: A multicenter, single-arm phase II trial was sponsored by the Spanish Group for Research on Sarcoma. Osteosarcoma patients, relapsed or progressing after standard chemotherapy and unsuitable for metastasectomy received gemcitabine and rapamycin p.o. 5 mg/day except for the same day of gemcitabine administration, and the day before. The main end point was 4-month progression-free survival rate (PFSR), with the assumption that rates higher than 40% would be considered as an active regimen. Translational research aimed to correlate biomarkers with the clinical outcome. RESULTS: Thirty-five patients were enrolled and received at least one cycle. PFSR at 4 months was 44%, and after central radiologic assessment, 2 partial responses and 14 stabilizations (48.5%) were reported from 33 assessable patients. The most frequent grade 3-4 adverse events were: neutropenia (37%), thrombocytopenia (20%), anemia (23%), and fatigue (15%); however, only three patients had febrile neutropenia. Positive protein expression of RRM1 significantly correlated with worse PFS and overall survival, while positivity of P-ERK1/2 was correlated with significant better overall survival. CONCLUSION: Gemcitabine plus sirolimus exhibits satisfactory antitumor activity and safety in this osteosarcoma population, exceeding the prespecified 40% of 4-month PFSR. The significant correlation of biomarkers with clinical outcome encourages further prospective investigation.

RESUMEN

This study analyzes patients with head and neck diffuse large B cell lymphoma (HN-DLBCL), focusing on the differences in the biological characteristics and prognosis of lymphomas of nodal and extranodal origin. We have included 72 patients with stage I-II HN-DLBCL who had updated survival information and diagnostic paraffin-embedded tissue blocks available for review. Non-germinal center phenotype (73.7 vs. 32.4 %, P = 0.001) and high level of Bcl-2 expression (78.9 vs. 52.9 %, P = 0.025) were more frequent in nodal than extranodal lymphomas. Univariate analyses indicated that bulky disease, Ann Arbor stage II, high level of Ki-67 expression, and primary nodal disease had adverse effects on complete remission (CR), but these effects were confirmed in a multivariate analysis for primary nodal disease and bulky disease. Patients with primary extranodal lymphoma also had better overall survival (OS) (87.7 vs. 72.5 %, P = 0.04) and event-free survival (EFS) (84 vs. 58.5 %, P = 0.046) than patients with nodal disease, although in the multivariate analysis, only Ann Arbor stage II continued to predict worse OS and EFS, whereas bulky disease was an independent prognostic factor only for EFS. We found significant differences in the biological characteristics and prognosis between primary nodal and extranodal HN-DLBCL.

RESUMEN

OBJECTIVES: The aim of this study was to investigate the rate at which the alumni of basic life support courses witnessed and intervened in out-of-hospital emergency situations, and to identify the variables characterizing those alumni associated with a greater number of witnessing events and interventions. An analysis of the efficiency of the courses was also carried out. DESIGN: A descriptive, cross-sectional study was made. SETTING: A district in the province of Almería (Spain). PATIENTS: Alumni of a mass basic life support training program targeted to the general population «Plan Salvavidas¼ conducted between 2003-2009. INTERVENTIONS: In 2010 the alumni were administered a telephone survey asking whether they had witnessed an emergency situation since attending the program, with the collection of information related to this emergency situation. MAIN VARIABLES OF INTEREST: Rate of out-of-hospital emergencies witnessed by the alumni. Rate of intervention of the alumni in emergency situations. Variables characterizing alumni with a greater likelihood of witnessing an emergency situation. RESULTS: A total of 3,864 trained alumni were contacted by telephone. Of 1,098 respondents, 63.9% were women, and the mean age was 26.61±10.6 years. Of these alumni, 11.75% had witnessed emergency situations, an average of three years after completing the course. Of these emergencies, 23.3% were identified as cardiac arrest. The alumni intervened in 98% of the possible cases. In 63% of the cases, there was no connection between the alumni and the victim. The majority of the emergency situations occurred in the street and in public spaces. A greater likelihood of witnessing an emergency situation was associated with being a healthcare worker and with being over 18 years of age. CONCLUSIONS: The rate of out-of-hospital emergencies witnessed by these alumni after the course was 11.75%. The level of intervention among the alumni was high. The most efficient target population consisted of healthcare workers.

RESUMEN

OBJECTIVE: To describe the aspects with the greatest impact on the satisfaction of patients treated in a multidisciplinary unit specialising in immune-mediated inflammatory diseases (IMIDs) and to identify areas for improvement in the care model. METHODS: Cross-sectional descriptive study using a satisfaction survey structured in three blocks: sociodemographic variables, functional aspects of the unit and satisfaction with the professionals. Immediate satisfaction was measured on aspects related to the care received, the physical structure and the likelihood of recommending the unit. RESULTS: A total of 168 patients completed the surveys, the mean score of overall satisfaction with the unit was 4.75 (SD:0.4). The regression model showed the relationship between overall satisfaction and unit signage (OR:3.558, p=0.045, 95% CI: 1.027-12.33), coordination between professionals (OR:9.043, p=0.000, 95% CI: 2.79-29.28) and participation in decision making (OR: 44.836, p=0.000, 95% CI: 5.49-365.97). In terms of immediate satisfaction, the overall Net Promoter Score (NPS) was 87 (excellent). The mean score for coordination with Primary Care was 4.54 (SD:0.8) and they scored waiting time to be seen with 4.49 (SD:0.8), so they have been considered an area for improvement The mean score for coordination with Primary Care was 4.54 (SD:0.8) and they scored waiting time to be seen with 4.49 (SD:0.8), so both were considered areas for improvement. CONCLUSIONS: Coordination between intra-centre professionals and patient participation in decision-making explain the excellent level of patient satisfaction. The monitoring of satisfaction has made it possible to implement immediate improvement actions.

RESUMEN

The discovery and first dates of the paintings in Grotte Chauvet provoked a new debate on the origin and characteristics of the first figurative Palaeolithic art. Since then, other art ensembles in France and Italy (Aldène, Fumane, Arcy-sur-Cure and Castanet) have enlarged our knowledge of graphic activity in the early Upper Palaeolithic. This paper presents a chronological assessment of the Palaeolithic parietal ensemble in Altxerri B (northern Spain). When the study began in 2011, one of our main objectives was to determine the age of this pictorial phase in the cave. Archaeological, geological and stylistic evidence, together with radiometric dates, suggest an Aurignacian chronology for this art. The ensemble in Altxerri B can therefore be added to the small but growing number of sites dated in this period, corroborating the hypothesis of more complex and varied figurative art than had been supposed in the early Upper Palaeolithic.

RESUMEN

Bird migratory journeys are often long and hostile, requiring high energetic expenditure, and thus forcing birds to pause between migratory flights. Stopover sites allow migrants to replenish fuel reserves and rest, being crucial for the success of migration. Worldwide, the increasing accumulation of waste on landfills and rubbish dumps has been described to provide superabundant food resources for many bird species not only during the breeding and wintering seasons but also during migration, being used as stopover sites. Using GPS-tracking data of juvenile white storks (Ciconia ciconia) during their first migration from the Iberia Peninsula to the sub-Saharan wintering grounds, we uncover the effects of stopping en route on individual migratory performance. Particularly, we examine the benefits of stopping at artificial sites (landfills and rubbish dumps) when compared to natural stopover sites (wetlands, agricultural or desert areas) and explore the influence of anthropogenic food resources on storks' migratory strategies. Overall, white storks spent up to one-third of the migration in stopovers. We found that birds that stopped for longer periods made more detours, increasing migration duration by half a day for each stopover day. Stopping more often did not reflect on increasing in-flight energetic efficiency nor the likelihood of completing the migration. Juvenile storks used artificial sites in 80 % of the stopover days, spending 45 % less time and 10 % less energy foraging than when using natural stopovers. While stopping in landfills did not translate into differences in migratory performance, individuals in poor body condition possibly rely on these sites to improve body weight before proceeding, enabling them to successfully complete migration. Artificial stopover sites are attractive and likely increase the number and duration of stops for white storks. Even though the consequences of arriving late at the wintering grounds are unknown, it can lead to cascading consequences, influencing individual fitness and population dynamics.

RESUMEN

BACKGROUND: Conventional cytotoxic drugs are not effective in alveolar soft-part sarcoma (ASPS). Immune checkpoint (programmed cell death protein 1/programmed death-ligand 1) inhibitors (ICIs) are promising drugs in ASPS. A worldwide registry explored the efficacy of ICI in ASPS. MATERIALS AND METHODS: Data from adult patients diagnosed with ASPS and treated with ICI for advanced disease in expert sarcoma centers from Europe, Australia and North America were retrospectively collected, including demographics and data related to treatments and outcome. RESULTS: Seventy-six ASPS patients, with a median age at diagnosis of 25 years (range 3-61 years), were registered. All patients received ICI for metastatic disease. Immunotherapy regimens consisted of monotherapy in 38 patients (50%) and combination in 38 (50%) (23 with a tyrosine kinase inhibitor). Among the 68 assessable patients, there were 3 complete responses and 34 partial responses, translating into an overall response rate of 54.4%. After a median follow-up of 36 months [95% confidence interval (CI) 32-40 months] since the start of immunotherapy, 45 (59%) patients have progressed on ICI, with a median progression-free survival (PFS) of 16.3 months (95% CI 8-25 months). Receiving ICI in first line (P = 0.042) and achieving an objective response (P = 0.043) correlated with a better PFS. Median estimated overall survival (OS) from ICI initiation has not been reached. The 12-month and 24-month OS rates were 94% and 81%, respectively. CONCLUSIONS: This registry constitutes the largest available series of ASPS treated with ICI. Our results suggest that the ICI treatment provides long-lasting disease control and prolonged OS in patients with advanced ASPS, an ultra-rare entity with limited active therapeutic options.

RESUMEN

INTRODUCTION: N19S mutation is produced by substitution in the 139 position of SOD1 and was described by Mayeux in a patient with amyotrophic lateral sclerosis (ALS). He suggested that it did not have a causal effect as it was found in asymptomatic and sporadic cases. Other authors in later articles did not agree. MATERIAL AND METHODS: We describe a family with 4 members with ALS patients and attempt to find the carrier of the N19S mutation of the propositus. Molecular studies were performed on 15 members of the family of a different order. RESULTS: The ALS cases were found in the maternal line of the propositus. The presence of the mutation was detected in 3 people, the other two were asymptomatic. One of patients with ALS in the family, who died previously, did not have the mutation. Two of the sons of this case and another of the other case did not show it. On the other hand, N19S mutation was only present in paternal branch of the propositus, where there were no cases. CONCLUSION: The described family supports the hypothesis by Mayeux and against that mutation N19S has pathological consequences, since mutation is only in the family line where there are no cases with ALS. In consequence, although the described case is included as a familiar form, it cannot be attributed to the mutation, and its relationship with N19S should be considered as casual.

RESUMEN

Airway isolation by endotracheal intubation or tracheostomy impedes or even interrupts speech and swallowing. Pharyngeal and laryngeal impairment frequently occurs after extubation or de-cannulation, common consequences being dysphonia, dysphagia and the aspiration of oral secretions, food, or fluids. Aspiration often leads to pneumonia and eventually death. Although the literature reports a high frequency of dysphagia following intubation and tracheostomy, the data vary considerably, and the true incidence of oropharyngeal dysphagia following artificial airway isolation remains to be established. We conducted a systematic review of the available evidence, in order to assess oropharyngeal dysphagia physiology, diagnosis and treatment.

RESUMEN

BACKGROUND AND AIM: To determine the impact of the COVID-19 pandemic on the epidemiology of safety incidents (SI) and medication errors (ME) reported to the CISEMadrid notification system in the hospital and primary care settings of the Madrid Health Service (SERMAS). MATERIALS AND METHODS: Observational and descriptive study with a retrospective analysis of data including all CISEMadrid notifications from 01-Jan-2018 to 31-Dec-2020, from 33 hospitals and 262 health care centres of the SERMAS. The two periods in 2020 with the greatest increase in COVID-19 cases were identified to compare incidents reported in the pre-pandemic and pandemic periods. RESULTS: 36,494 incidents were reported. Comparing both periods, an overall decrease in pandemic notifications of 60.7% was observed, being higher in primary care, falling to 33% of previous levels. The reduction in notifications was similar in the peaks and valleys of the waves. The three most frequent SIs in both periods and care settings were: diagnostic tests, medical devices/equipment/clinical furniture and organisational management/citations. In ME, dose failure and inappropriate selection were the most frequent in both settings and periods. There were no relevant differences in patient consequences in both periods. CONCLUSIONS: During the pandemic, patient safety notifications decreased although the most frequent types remained the same, as did their impact on the patient, both in hospitals and in primary care. The safety culture of organisations is a critical aspect for the maintenance of reporting systems.
