    Introduction: Androgen receptor pathway inhibitors (ARPIs) have been increasingly offered to older patients with prostate cancer (PC). However, prognostic factors relevant to their outcome with ARPIs are still little investigated. Methods and Materials: The Meet-URO network ADHERE was a prospective multicentre observational cohort study evaluating and monitoring adherence to ARPIs metastatic castrate-resistant PC (mCRPC) patients aged ≥70. Cox regression univariable and multivariable analyses for radiographic progression-free (rPFS) and overall survival (OS) were performed. Unsupervised median values and literature-based thresholds where available were used as cut-offs for quantitative variables. Results: Overall, 234 patients were enrolled with a median age of 78 years (73–82); 86 were treated with abiraterone (ABI) and 148 with enzalutamide (ENZ). With a median follow-up of 15.4 months (mo.), the median rPFS was 26.0 mo. (95% CI, 22.8–29.3) and OS 48.8 mo. (95% CI, 36.8–60.8). At the MVA, independent prognostic factors for both worse rPFS and OS were Geriatric G8 assessment ≤ 14 (p < 0.001 and p = 0.004) and PSA decline ≥50% (p < 0.001 for both); time to castration resistance ≥ 31 mo. and setting of treatment (i.e., post-ABI/ENZ) for rPFS only (p < 0.001 and p = 0.01, respectively); age ≥78 years for OS only (p = 0.008). Conclusions: Baseline G8 screening is recommended for mCRPC patients aged ≥70 to optimise ARPIs in vulnerable individuals, including early introduction of palliative care

    INTRODUCCIÓN: La enfermedad tromboembólica venosa (ETV) es una patología que aumenta con la edad. Objetivo: comparar la sobrevida de los ancianos y los jóvenes con un primer episodio de ETV aguda y sintomática. MATERIALES Y MÉTODOS: Cohorte prospectiva de casos incidentes de ETV incluidos en el Registro Institucional de Enfermedad Tromboembólica venosa (NCT01372514) del Hospital Italiano de Buenos Aires entre 2012-2014, dividido en grupos jóvenes (17-64 años) y ancianos (≥ 65 años). Todos los pacientes fueron seguidos anualmente para evaluar el tiempo a la recurrencia (progresión o nuevo evento sintomático de ETV) como eventos competitivos en contexto de muerte y sangrado mayor. Se presentaron los riesgos crudos (c) y ajustados (a). RESULTADOS: se incluyeron 446 pacientes, el 63% (292) fueron mayores de 65 años. La sobrevida fue menor en los ancianos comparados con los jóvenes (p 0.007), a los 3 meses 87% vs 95% y al año 73% vs 87%, respectivamente. Los ancianos presentaron un HRc1,71 y HR a 1.68. La recurrencia global fue 5% (IC 95% 3-8) al mes, 6% (IC 95% 4-9) a los 3 meses, 8% (IC 95% 6-11) al año y 13% (IC 95% 9-18) a los dos años. No se encontró asociación entre la edad y la recurrencia sub hazard 0.8(IC 0,34-1,86). El sangrado ocurrió en un 9% (39) de los pacientes. CONCLUSIONES: La mortalidad global en pacientes con ETV confirmada es mayor en la población anciana. No hubo diferencias en relación a la recurrencia de ETV, ni el sangrado y tampoco con la edad.INTRODUCTION: Venous thromboembolic disease (VTE) is a pathology that increases with age. OBJECTIVE: to compare the survival of the elderly and the young with a first episode of acute and symptomatic VTE. MATERIALS AND METHODS: Prospective cohort of incident VTE cases included in the Institutional Registry of Venous Thromboembolic Disease (NCT01372514) of the Italian Hospital of Buenos Aires between 2012-2014, divided into young groups (17-64 years old) and elderly (65 years old). All the patients were followed annually to assess the time to recurrence (progression or new symptomatic event of VTE) as competitive events in the context of death and major bleeding. Raw (c) and adjusted (a) risks were presented. RESULTS: 446 patients were included, 63% (292) were older than 65 years. Survival was lower in the elderly compared to the young (p 0.007), at 3 months 87% vs. 95% and at one year 73% vs. 87%, respectively. The elderly had a HRc1.71 and HR at 1.68. The overall recurrence was 5% (95% CI 3-8) at one month, 6% (95% CI 4-9) at 3 months, 8% (95% CI). 6-11) at one year and 13% (95% CI 9-18) at two years. No association was found between age and recurrence sub hazard 0.8 (CI 0.34- 1.86). Bleeding occurred in 9% (39) of the patients. CONCLUSIONS: The overall mortality in patients with confirmed VTE is higher in the elderly population. There were no differences in relation to the recurrence of VTE, or bleeding, and neither with age.INTRODUÇÃO: A doença tromboembólica venosa (TEV) é uma patologia que aumenta com a idade.

    Involvement of GTA protein NC2β in Neuroblastoma pathogenesis suggests that it physiologically participates in the regulation of cell proliferation

    <p>Abstract</p> <p>Background</p> <p>The General Transcription Apparatus (GTA) comprises more than one hundred proteins, including RNA Polymerases, GTFs, TAFs, Mediator, and cofactors such as heterodimeric NC2. This complexity contrasts with the simple mechanical role that these proteins are believed to perform and suggests a still uncharacterized participation to important biological functions, such as the control of cell proliferation.</p> <p>Results</p> <p>To verify our hypothesis, we analyzed the involvement in Neuroblastoma (NB) pathogenesis of GTA genes localized at 1p, one of NB critical regions: through RT-PCR of fifty eight NB biopsies, we demonstrated the statistically significant reduction of the mRNA for NC2β (localized at 1p22.1) in 74% of samples (p = 0.0039). Transcripts from TAF13 and TAF12 (mapping at 1p13.3 and 1p35.3, respectively) were also reduced, whereas we didn't detect any quantitative alteration of the mRNAs from GTF2B and NC2α (localized at 1p22-p21 and 11q13.3, respectively). We confirmed these data by comparing tumour and constitutional DNA: most NB samples with diminished levels of NC2β mRNA had also genomic deletions at the corresponding locus.</p> <p>Conclusion</p> <p>Our data show that NC2β is specifically involved in NB pathogenesis and may be considered a new NB biomarker: accordingly, we suggest that NC2β, and possibly other GTA members, are physiologically involved in the control of cell proliferation. Finally, our studies unearth complex selective mechanisms within NB cells.</p

    Background Passive immunotherapy has been evaluated as a therapeutic alternative for patients with COVID-19 disease. Equine polyclonal immunotherapy for COVID-19 (EPIC) showed adequate safety and potential efficacy in a clinical trial setting and obtained emergency use authorization in Argentina. We studied its utility in a real world setting with a larger population. Methods We conducted a retrospective cohort study at “Hospital de Campaña Escuela-Hogar" (HCEH) in Corrientes, Argentina, to assess safety and effectiveness of EPIC in hospitalized adults with severe COVID-19 pneumonia. Primary endpoints were 28-days all-cause mortality and safety. Mortality and improvement in modified WHO clinical scale at 14 and 21 days were secondary endpoints. Potential confounder adjustment was made by logistic regression weighted by the inverse of the probability of receiving the treatment (IPTW) and doubly robust approach. Findings Subsequent clinical records of 446 non-exposed (Controls) and 395 exposed (EPIC) patients admitted between November 2020 and April 2021 were analyzed. Median age was 58 years and 56.8% were males. Mortality at 28 days was 15.7% (EPIC) vs. 21.5% (Control). After IPTW adjustment the OR was 0.66 (95% CI: 0.46–0.96) P = 0.03. The effect was more evident in the subgroup who received two EPIC doses (complete treatment, n = 379), OR 0.58 (95% CI 0.39 to 0.85) P = 0.005. Overall and serious adverse events were not significantly different between groups. Conclusions In this retrospective cohort study, EPIC showed adequate safety and effectiveness in the treatment of hospitalized patients with severe SARS-CoV-2 disease.Fil: Farizano Salazar, Diego H..

    In this study the femtosecond near-IR and nanosecond green lasers are used to induce alterations in mitotic chromosomes. The subsequent double-strand break responses are studied. We show that both lasers are capable of creating comparable chromosomal alterations and that a phase paling observed within 1–2 s of laser exposure is associated with an alteration of chromatin as confirmed by serial section electron microscopy, DAPI, γH2AX and phospho-H3 staining. Additionally, the accumulation of dark material observed using phase contrast light microscopy (indicative of a change in refractive index of the chromatin) ∼34 s post-laser exposure corresponds spatially to the accumulation of Nbs1, Ku and ubiquitin. This study demonstrates that chromosomes selectively altered in mitosis initiate the DNA damage response within 30 s and that the accumulation of proteins are visually represented by phase-dark material at the irradiation site, allowing us to determine the fate of the damage as cells enter G1. These results occur with two widely different laser systems, making this approach to study DNA damage responses in the mitotic phase generally available to many different labs. Additionally, we present a summary of most of the published laser studies on chromosomes in order to provide a general guide of the lasers and operating parameters used by other laboratories

    IMPORTANCE Delays in screening programs and the reluctance of patients to seek medical attention because of the outbreak of SARS-CoV-2 could be associated with the risk of more advanced colorectal cancers at diagnosis. OBJECTIVE To evaluate whether the SARS-CoV-2 pandemic was associated with more advanced oncologic stage and change in clinical presentation for patients with colorectal cancer. DESIGN, SETTING, AND PARTICIPANTS This retrospective, multicenter cohort study included all 17 938 adult patients who underwent surgery for colorectal cancer from March 1, 2020, to December 31, 2021 (pandemic period), and from January 1, 2018, to February 29, 2020 (prepandemic period), in 81 participating centers in Italy, including tertiary centers and community hospitals. Follow-up was 30 days from surgery. EXPOSURES Any type of surgical procedure for colorectal cancer, including explorative surgery, palliative procedures, and atypical or segmental resections. MAIN OUTCOMES AND MEASURES The primary outcome was advanced stage of colorectal cancer at diagnosis. Secondary outcomes were distant metastasis, T4 stage, aggressive biology (defined as cancer with at least 1 of the following characteristics: signet ring cells, mucinous tumor, budding, lymphovascular invasion, perineural invasion, and lymphangitis), stenotic lesion, emergency surgery, and palliative surgery. The independent association between the pandemic period and the outcomes was assessed using multivariate random-effects logistic regression, with hospital as the cluster variable. RESULTS A total of 17 938 patients (10 007 men [55.8%]; mean [SD] age, 70.6 [12.2] years) underwent surgery for colorectal cancer: 7796 (43.5%) during the pandemic period and 10 142 (56.5%) during the prepandemic period. Logistic regression indicated that the pandemic period was significantly associated with an increased rate of advanced-stage colorectal cancer (odds ratio [OR], 1.07; 95%CI, 1.01-1.13; P = .03), aggressive biology (OR, 1.32; 95%CI, 1.15-1.53; P &lt; .001), and stenotic lesions (OR, 1.15; 95%CI, 1.01-1.31; P = .03). CONCLUSIONS AND RELEVANCE This cohort study suggests a significant association between the SARS-CoV-2 pandemic and the risk of a more advanced oncologic stage at diagnosis among patients undergoing surgery for colorectal cancer and might indicate a potential reduction of survival for these patients

    Large expert-curated database for benchmarking document similarity detection in biomedical literature search

    Document recommendation systems for locating relevant literature have mostly relied on methods developed a decade ago. This is largely due to the lack of a large offline gold-standard benchmark of relevant documents that cover a variety of research fields such that newly developed literature search techniques can be compared, improved and translated into practice. To overcome this bottleneck, we have established the RElevant LIterature SearcH consortium consisting of more than 1500 scientists from 84 countries, who have collectively annotated the relevance of over 180 000 PubMed-listed articles with regard to their respective seed (input) article/s. The majority of annotations were contributed by highly experienced, original authors of the seed articles. The collected data cover 76% of all unique PubMed Medical Subject Headings descriptors. No systematic biases were observed across different experience levels, research fields or time spent on annotations. More importantly, annotations of the same document pairs contributed by different scientists were highly concordant. We further show that the three representative baseline methods used to generate recommended articles for evaluation (Okapi Best Matching 25, Term Frequency-Inverse Document Frequency and PubMed Related Articles) had similar overall performances. Additionally, we found that these methods each tend to produce distinct collections of recommended articles, suggesting that a hybrid method may be required to completely capture all relevant articles. The established database server located at https://relishdb.ict.griffith.edu.au is freely available for the downloading of annotation data and the blind testing of new methods. We expect that this benchmark will be useful for stimulating the development of new powerful techniques for title and title/abstract-based search engines for relevant articles in biomedical research.Peer reviewe

    The mediational role of values in linking personality traits to civic engagement in Italian youth

    No full text
    In recent decades, given new forms of political participation, the involvement of young people in the civic domain begins to be a focus of many studies. The present study examined the role of personality traits and personal values in the prediction of civic engagement (CE) in Italian youth ranging in age from 19 to 29 years old involved in an ongoing longitudinal study. The multidimensionality of a scale tapping CE has been demonstrated with the examination of confirmatory factor analysis. Structural equation modeling corroborated a mediational model in which benevolence fully mediated the relationship of the traits of agreeableness and openness with civic associationism, whereas power fully mediated the relationship of the traits of agreeableness and openness with political associationism. In this mediational model men reported higher levels of power than women, whereas women reported higher levels of agreeableness and openness traits. Since basic personal traits have been identified as the root of any behavioral tendency and values have been recognized as the more flexible and changeable variables, future interventions aimed to foster CE in youth could be designed considering the strength relationship between the examined dimensions in the present study. © 2012 CIRMPA

    The physical activity and sport are key elements for a healthy lifestyle. However, a little-investigated element is the presence of a possible relationship between school or academic performance and the participation in physical activity and sport in groups of preadolescents and adolescents. In order to clarify the complex relationship between mind and body in preadolescence and adolescence, the present discussion investigates the causal and direct relationship between sport activity and performance; and describes how this relationship can be mediated by the sense of self-esteem and self-efficacy; and investigates the relationship between group sports practice and school or academic performance
