RESUMO

Deregulation of small non-coding RNAs (sncRNAs) has been associated with the onset of metastasis. We evaluated the expression of sncRNAs in patients with early-stage breast cancer, performing RNA sequencing in 60 patients for whom tumor and sentinel lymph node (SLN) samples were available, and conducting differential expression, gene ontology, enrichment and survival analyses. Sequencing annotation classified most of the sncRNAs into small nucleolar RNA (snoRNAs, 70%) and small nuclear RNA (snRNA, 13%). Our results showed no significant differences in sncRNA expression between tumor or SLNs obtained from the same patient. Differential expression analysis showed down-regulation (n = 21) sncRNAs and up-regulation (n = 2) sncRNAs in patients with locoregional metastasis. The expression of SNHG5, SNORD90, SCARNA2 and SNORD78 differentiated luminal A from luminal B tumors, whereas SNORD124 up-regulation was associated with luminal B HER2+ tumors. Discriminating analysis and receiver-operating curve analysis revealed a signature of six snoRNAs (SNORD93, SNORA16A, SNORD113-6, SNORA7A, SNORA57 and SNORA18A) that distinguished patients with locoregional metastasis and predicted patient outcome. Gene ontology and Reactome pathway analysis showed an enrichment of biological processes associated with translation initiation, protein targeting to specific cell locations, and positive regulation of Wnt and NOTCH signaling pathways, commonly involved in the promotion of metastases. Our results point to the potential of several sncRNAs as surrogate markers of lymph node metastases and patient outcome in early-stage breast cancer patients. Further preclinical and clinical studies are required to understand the biological significance of the most significant sncRNAs and to validate our results in a larger cohort of patients.

RESUMO

Secreted protein acidic and rich in cysteine (SPARC) expression has been proposed as a prognostic and predictive biomarker for some cancer types, but knowledge about the predictive value of SPARC polymorphisms in the context of neoadjuvant therapy for breast cancer (BC) is lacking. In 132 HER2-negative BC patients treated with neoadjuvant chemotherapy, we determined polymorphisms in the SPARC gene and analyzed their association with outcome. We also determined SPARC protein expression in tumor tissue. SPARC rs19789707 was significantly associated with response to treatment according to the Miller and Payne system in the breast (multivariate: odds ratio (OR), 3.81; p = 0.028). This association was significant in the subgroup of patients with luminal tumors (univariate: p = 0.047). Regarding survival, two SPARC variants showed significant associations with event-free survival: the rs19789707 variant in the subgroup of luminal A tumors (univariate: p = 0.006), and the rs4958487 variant in the subgroup of luminal B tumors (univariate: p = 0.022). In addition, SPARC rs4958487, rs10065756, and rs12153644 were significantly correlated with SPARC protein expression. Our findings suggest that SPARC polymorphisms could be good predictors of treatment response and survival in BC patients treated with neoadjuvant chemotherapy, especially those with luminal tumors.

RESUMO

BACKGROUND: We aimed to describe infective endocarditis cases from noncardiac surgery centers, as current knowledge on infective endocarditis is derived mostly from cardiac surgery hospitals. METHODS: An observational retrospective study (2009-2018) was conducted in 9 noncardiac surgery hospitals in Central Catalonia. All adult patients diagnosed with definitive infective endocarditis were included. Transferred and nontransferred cohorts were compared, and a logistic regression model was used to ascertain the prognostic factors. RESULTS: Overall, 502 infective endocarditis episodes were included: 183 (36.5%) were transferred to the cardiac surgery center, whereas 319 were not, with (18.7%) and without (45%) surgical indications. Cardiac surgery was performed in 83% of transferred patients. In-hospital (14% vs 23%) and 1-year (20% vs 35%) mortality rates were significantly lower in transferred patients (P < .001). Among the patients not undergoing cardiac surgery despite an indication, 55 (54%) died within 1 year. The multivariate analysis identified the following independent predictive factors for in-hospital mortality: Staphylococcus aureus infective endocarditis (odds ratio: 1.93 [1.08, 3.47]), heart failure (odds ratio: 3.87 [2.28, 6.57]), central nervous system embolism (odds ratio: 2.95 [1.41, 5.14]), and Charlson score (odds ratio: 1.19 [1.09, 1.30]), whereas community acquisition (odds ratio: 0.52 [0.29, 0.93]), cardiac surgery (odds ratio: 0.42 [0.20, 0.87]), but not transfer (odds ratio: 1.23 [0.84, 3.95]) were identified as protective factors. One-year mortality was associated with S. aureus infective endocarditis (odds ratio: 1.82 [1.04, 3.18]), heart failure (odds ratio: 3.74 [2.27, 6.16]), and Charlson score (odds ratio: 1.23 [1.13, 1.33]), whereas cardiac surgery (odds ratio: 0.41 [0.21, 0.79]) was identified as a protective factor. CONCLUSION: Patients not transferred to a referral cardiac surgery center have a worse prognosis compared to those ultimately transferred, as cardiac surgery is associated with lower mortality rates.

RESUMO

Background: Cancer has been associated with an increased risk of in-hospital mortality in CDI patients. However, data on delayed mortality in cancer patients with CDI are scarce. Aim/Objective: The aim of the present study was to compare outcomes between oncological patients and the general population with Clostridioides difficile infection (CDI) after 90 days of follow-up. Methods: A multicenter prospective cohort study was conducted in 28 hospitals participating in the VINCat program. Cases were all consecutive adult patients who met the case definition of CDI. Sociodemographic, clinical, and epidemiological variables and evolution at discharge and after 90 days were recorded for each case. Findings/results: The mortality rate was higher in oncological patients (OR = 1.70, 95% CI: 1.08-2.67). In addition, oncological patients receiving chemotherapy (CT) presented higher recurrence rates (18.5% vs 9.8%, p = 0.049). Among oncological patients treated with metronidazole, those with active CT showed a higher rate of recurrence (35.3% vs 8.0% p = 0.04). Discussion: Oncological patients presented a higher risk of poor outcomes after CDI. Their early and late mortality rates were higher than in the general population, and in parallel, those undergoing chemotherapy (especially those receiving metronidazole) had higher rates of recurrence.

RESUMO

OBJECTIVE: to analyze the presence of common personality traits and anxiety states in children and adolescents with inflammatory bowel disease (IBD). PATIENTS AND METHOD: Longitudinal, prospecti ve, and analytical study by applying the questionnaires Children's Personality Questionnaire, High School Personality Questionnaire, State-Trait Anxiety Inventory for Children, and State-Trait Anxie ty Inventory for patients with IBD aged between 9 and 18 years seen at reference IBD units in Ara gon, Spain. The participants excluded were those with active disease, defined as a score > 10 on the Pediatric Crohn's Disease Activity Index (PCDAI Score) or > 10 on the Pediatric Ulcerative Colitis Activity Index (PUCAI Score). RESULTS: Twenty-six patients participated (73% male). 61.5% pre sented Crohn's disease (CD) and 38.5% ulcerative colitis (UC). No patient presented active disease. The personality profile as a group was characterized by being open, emotionally stable, calm, sober, sensible, enterprising, impressionable, dependent, serene, perfectionist, and relaxed. 50% of the CD patients were enterprising versus no UC patients (p < 0.05). There were no statistically significant di fferences when comparing the remaining personality factors based on IBD type, age, or sex. Patients with CD tended to be calmer (p = 0.0511) and patients with UC more introverted (p = 0.0549). The sample presented a state anxiety level (A/E) -1.1 ± 0.8 SD compared with the population average. The level of anxiety as a feature (A/R) was -0.6 ± 1 SD. Males had significantly lower levels than females in the case of A/E (p < 0.05). CONCLUSIONS: The presence of common personality traits in the pediatric population with IBD stands out but there was no greater anxiety than in the reference population.

RESUMO

Resumen Introducción: El flutter auricular es un tipo poco frecuente de arritmia fetal y neonatal. A pesar de que puede conducir a graves morbilidades, como hidrops fetal o incluso el fallecimiento, el diagnóstico y tratamiento precoz confieren un buen pronóstico a la mayoría de los casos. Pacientes y métodos: Se presentan tres casos de flutter auricular, dos de inicio en periodo fetal y uno en periodo neonatal, y se revisa la literatura en relación con las características clínicas, diagnósticas y terapéuticas del flutter auricular fetal y neonatal. Resultados y discusión: En el flutter auricular fetal la terapia materna con fármacos antiarrítmicos es el tratamiento más empleado durante la gestación. El tratamiento postnatal más utilizado es la cardioversión eléctrica sincronizada. El flutter auricular no suele asociar cardiopatía estructural; la recidiva neonatal es poco habitual y normalmente no precisa la administración de tratamiento profiláctico.


Abstract Introduction: Atrial flutter is a rare type of fetal and neonatal arrhythmia. Although it can lead to serious morbidities such as fetal hydrops or even death, diagnosis and early treatment confer a good prognosis in most cases. Patients and methods: Three cases of atrial flutter are presented, two of which start in the fetal period and one in the neonatal period. The literature is reviewed in relation to the clinical, diagnostic and therapeutic characteristics of fetal and neonatal atrial flutter. Results and discussion: In fetal atrial flutter maternal therapy with antiarrhythmic drugs is the most used treatment during pregnancy. The most used postnatal treatment is synchronized electrical cardioversion. Atrial flutter does not usually associate structural heart disease, neonatal recurrence is uncommon and usually does not require prophylactic treatment.

RESUMO

Histone H1 is the most variable histone and its role at the epigenetic level is less characterized than that of core histones. In vertebrates, H1 is a multigene family, which can encode up to 11 subtypes. The H1 subtype composition is different among cell types during the cell cycle and differentiation. Mass spectrometry-based proteomics has added a new layer of complexity with the identification of a large number of post-translational modifications (PTMs) in H1. In this review, we summarize histone H1 PTMs from lower eukaryotes to humans, with a particular focus on mammalian PTMs. Special emphasis is made on PTMs, whose molecular function has been described. Post-translational modifications in H1 have been associated with the regulation of chromatin structure during the cell cycle as well as transcriptional activation, DNA damage response, and cellular differentiation. Additionally, PTMs in histone H1 that have been linked to diseases such as cancer, autoimmune disorders, and viral infection are examined. Future perspectives and challenges in the profiling of histone H1 PTMs are also discussed.

RESUMO

BACKGROUND: The clinical benefit and pricing of breakthrough-designated cancer drugs are uncertain. This study compares the magnitude of the clinical benefit and monthly price of new and supplemental breakthrough-designated and non-breakthrough-designated cancer drug approvals. METHODS: A cross-sectional cohort comprised approvals of cancer drugs for solid tumors from July 2012 to December 2017. For each indication, the clinical benefit from the pivotal trials was scored via validated frameworks: the American Society of Clinical Oncology Value Framework (ASCO-VF), the American Society of Clinical Oncology Cancer Research Committee (ASCO-CRC), the European Society for Medical Oncology Magnitude of Clinical Benefit Scale (ESMO-MCBS), and the National Comprehensive Cancer Network (NCCN) Evidence Blocks. A high clinical benefit was defined as scores ≥ 45 for the ASCO-VF, overall survival gains ≥ 2.5 months or progression-free survival gains ≥ 3 months for all cancer types for the ASCO-CRC criteria, a grade of A or B for trials of curative intent and a grade of 4 or 5 for trials of noncurative intent for the ESMO-MCBS, and scores of 4 and 5 and a combined score ≥ 16 for the NCCN Evidence Blocks. Monthly Medicare drug prices were calculated with Medicare prices and DrugAbacus. RESULTS: This study identified 106 trials supporting approval of 52 drugs for 96 indications. Forty percent of these indications received the breakthrough designation. Among the included trials, 33 (43%), 46 (73%), 35 (34%), and 67 (69%) met the thresholds established by the ASCO-VF, ASCO-CRC, ESMO-MCBS, and NCCN, respectively. In the metastatic setting, there were higher odds of clinically meaningful grades in trials supporting breakthrough drugs with the ASCO-VF (odds ratio [OR], 3.69; P = .022) and the NCCN Evidence Blocks (OR, 5.80; P = .003) but not with the ASCO-CRC (OR, 3.54; P = .11) or version 1.1 (v1.1) of the ESMO-MCBS (OR, 1.22; P = .70). The median costs of breakthrough therapy drugs were significantly higher than those of nonbreakthrough therapies (P = .001). CONCLUSIONS: In advanced solid cancers, drugs that received the breakthrough therapy designation were more likely than nonbreakthrough therapy drugs to be scored as providing a high clinical benefit with the ASCO-VF and the NCCN Evidence Blocks but not with the ESMO-MCBS v1.1 or the ASCO-CRC scale.

RESUMO

INTRODUCTION: Clinical and pathological characteristics are still considered prognostic markers in metastatic non-small-cell lung cancer (NSCLC) patients but they cannot explain all interindividual variability. Tumoral angiogenesis mediated by the vascular endothelial growth factor (VEGF) is critical for the progression and metastasis of the disease. We aimed to investigate the prognostic role of genetic variants within the VEGF pathway in patients with metastatic NSCLC. MATERIALS AND METHODS: We prospectively included 170 patients with metastatic NSCLC treated with first-line platinum-based chemotherapy. A comprehensive panel of single-nucleotide polymorphisms (SNPs) in genes belonging to the VEGF pathway (VEGFA, VEGFR1/FLT1, VEGFR2/KDR, GRB2, ITGAV, KISS1, KRAS, PRKCE, HIF1α, MAP2K4, MAP2K6, and MAPK11) were genotyped in blood DNA samples. SNPs were evaluated for association with overall survival (OS) and progression-free survival (PFS). RESULTS: In multivariate analyses adjusted for patient characteristics, we found that VEGFA rs2010963 and VEGFR2 rs2071559 were significantly associated with OS [Hazard Ratio (HR) 0.7 (0.5-0.9); p = 0.026 and HR 1.5 (1.1-2.3); p = 0.025, respectively]. Additionally, ITGAV rs35251833 and MAPK11 rs2076139 were significantly associated with PFS [HR 2.5 (1.4-4.3; p = 0.002 and HR 0.6 (0.5-0.9); p = 0.013, respectively]. CONCLUSION: Our findings reinforce the potential clinical value of germline variants in VEGFA and VEGFR2 and show for the first time variants in ITGAV and MAPK11 as promising prognostic markers in metastatic NSCLC patients receiving platinum-based chemotherapy.

RESUMO

Pneumococcal conjugate vaccine (PCV13) has been recently added to the vaccine recommendations for immunosuppressed adults (ISP). We conducted a multicenter observational prospective study aimed to assess the evolving epidemiology of invasive pneumococcal disease (IPD) in adults, with especial focus on ISP. All IPD cases admitted from 1999 to 2014 were included. ISP was defined as patients on current cancer chemotherapy, immunosuppressive therapy for autoimmune disease, biological therapy, chronic systemic steroid use, hemodialysis, neutropenia or HIV infection. A total of 799 IPD episodes were analyzed, 198 were considered ISP. IPD incidence decreased from 20 to 8/100,000-population year (p < 0.004) over the study period. No changes in mortality were observed. Penicillin resistance experienced a significant decline. In 694 episodes the serotype was known. Global vaccine coverage considering the whole study period, was for PCV7 21.6% vs. 28.8% in general and in immunosuppressed population (p = 0.04) and for PCV13 64.5% and 56.6% respectively (p = 0.05). The proportion of IPD isolates included in PCV7 and PCV13 significantly decreased over time. A reduction in the incidence of IPD in adults was seen late after the vaccine licensure, both in general population and in ISP. Coverage of PCV13 vaccine might be suboptimal for ISP in the coming years.

RESUMO

To characterize the anticonvulsant effects and types of interactions exerted by mixtures of vigabatrin (VGB) and conventional antiepileptic drugs (valproate (VPA), ethosuximide (ESM), phenobarbital (PB), and clonazepam (CZP)) in pentylenetetrazole (PTZ)-induced seizures in mice, the isobolographic analysis for three fixed-ratio combinations of 1 : 3, 1 : 1, and 3 : 1 was used. The adverse-effect profile of the combinations tested, at the doses corresponding to their median effective doses (ED(50)) at the fixed-ratio of 1 : 1 against PTZ-induced seizures, was determined by the chimney (motor performance), step-through passive avoidance (long-term memory), pain threshold (pain sensitivity), and Y-maze (general explorative locomotor activity) tests in mice. Additionally, the observed isobolographic interactions were verified in terms of a pharmacokinetic interaction existence. VGB combined with PB or ESM exerted supra-additive (synergistic) interactions against the clonic phase of PTZ-induced seizures, which was associated with the increment of PB or ESM concentrations in the brains of examined animals. The remaining combinations tested (ie VGB+VPA and VGB+CZP) occurred additive in the PTZ test, which was associated with no significant changes in the brain concentrations of VPA and CZP. None of the examined combinations exerted motor impairment in the chimney test in mice. In the standard variant of passive avoidance task (current of 0.6 mA; 2 s of stimulus duration), the combinations of VGB+CZP and VGB+VPA significantly affected long-term memory in mice. Moreover, VGB in a dose-dependent manner lengthened the latency to the first pain reaction in the pain threshold test in mice. The modified variant of step-through passive avoidance task (current of 0.6 mA; stimulus duration based on the latency from the pain threshold test) revealed no significant changes in the long-term memory of animals for the combinations of VGB+VPA and VGB+CZP; so the observed effects in the standard variant of passive avoidance task were a result of the antinociceptive effects produced by VGB. In the Y-maze test, VGB also, in a dose-dependent manner, increased the general explorative locomotor activity of the animals tested. Similarly, the total number of arm entries in the Y-maze was significantly increased for the combinations of VGB+CZP and VGB+ESM, but not for VGB+PB and VGB+VPA. The application of VGB in combination with PB, ESM, CZP, and VPA suppressed the clonic phase of PTZ-induced seizures, having no harmful or deleterious effects on behavioral functioning of the animals tested, which might be advantageous in further clinical practice.

RESUMO

Presentamos 2 pacientes portadores de celulitis necrotizantes cérvico mediastinales, de origen dentario. Se analizan las vías de diseminación, etiologías más frecuentes y presentación clínica. Le damos importancia a la TAC cérvico torácica como el examen de jerarquía para valorar el compromiso mediastinal. Discutimos las vías de abordaje quirúrgico, ya sea cervicales o cervicotorácicas, planteando el abordaje videotoracóscopico en manos experimentadas. Concluimos que el diagnóstico debe ser precoz, y el tratamiento debe ser de emergencia como única forma de evitar la alta mortalidad de esta entidad.
