RESUMO

BACKGROUND: Coronary heart disease is the leading cause of heart failure (HF), and tools are needed to identify patients with a higher probability of developing HF after an acute coronary syndrome (ACS). Artificial intelligence (AI) has proven to be useful in identifying variables related to the development of cardiovascular complications. METHODS: We included all consecutive patients discharged after ACS in two Spanish centers between 2006 and 2017. Clinical data were collected and patients were followed up for a median of 53months. Decision tree models were created by the model-based recursive partitioning algorithm. RESULTS: The cohort consisted of 7,097 patients with a median follow-up of 53months (interquartile range: 18-77). The readmission rate for HF was 13.6% (964 patients). Eight relevant variables were identified to predict HF hospitalization time: HF at index hospitalization, diabetes, atrial fibrillation, glomerular filtration rate, age, Charlson index, hemoglobin, and left ventricular ejection fraction. The decision tree model provided 15 clinical risk patterns with significantly different HF readmission rates. CONCLUSIONS: The decision tree model, obtained by AI, identified 8 leading variables capable of predicting HF and generated 15 differentiated clinical patterns with respect to the probability of being hospitalized for HF. An electronic application was created and made available for free.

RESUMO

Fire blight, caused by the plant-pathogenic bacterium Erwinia amylovora, is a highly contagious and difficult-to-control disease due to its efficient dissemination and survival and the scarcity of effective control methods. Copper and antibiotics are the most used treatments but pose environmental and human health risks. Bacteriophages (phages) constitute an ecological, safe, and sustainable fire blight control alternative. The goal of this study was to search for specific E. amylovora phages from plant material, soil, and water samples in Mediterranean environments. A collection of phages able to specifically infect and lyse E. amylovora strains was generated from former fire blight-affected orchards in Eastern Spain. Following in vitro characterization, assays in immature fruit revealed that preventively applying some of the phages or their combinations delayed the onset of fire blight symptoms and reduced the disease's severity, suggesting their biocontrol potential in Spain and other countries. The morphological and molecular characterization of the selected E. amylovora phages classified them as members of the class Caudoviricetes (former Myoviridae family) and genus Kolesnikvirus. This study reveals Mediterranean settings as plausible sources of E. amylovora-specific bacteriophages and provides the first effective European phage cocktails in plant material for the development of sustainable fire blight management measures.

RESUMO

BACKGROUND: This paper addresses the lack of research that compares the toxicity of commonly used construction materials. The toxicity of construction materials has received less attention, despite its importance within the Life Cycle Assessment methodology. All aspects, including toxicity, need to be analysed throughout the life cycle of the material to understand its true behaviour. AIM: The purpose of this study is to propose a methodology to compare the toxicity of different construction materials and highlight the need to consider toxicity criteria in the selection of materials during the design phase. The study seeks to fill the gap in the existing literature by providing information on the comparative toxicity of the most common building materials. METHODOLOGY: The study follows Life Cycle Assessment methodology as established by the ISO 14040:2006 and ISO 14044:2006 standards. For this study, statistics were consulted to identify the most used materials in the construction sector; then, from this group of materials, those available in the Ecoinvent 3.7.1 database were selected. For comparison, these materials were categorised into material families and a functional unit was established to compare them. Finally, all materials were compared with each other, using 1 kg as the functional unit. RESULTS: When we conduct a comparative analysis of various materials and categorise them into groups, it becomes readily apparent which materials demonstrate a less favourable performance with respect to their toxic properties. This approach allows us to discern and pinpoint those materials that present a more concerning level of toxicity relative to others, facilitating informed decision-making in terms of construction material selection and design. CONCLUSIONS: By comparing all materials with each other using 1 kg as the functional unit, we can conclude that some materials have a greater impact than others, both in absolute and relative terms, for example, steel and polyurethane foam.

RESUMO

Besides its importance as a livestock species, pig is increasingly being used as an animal model for biomedical research. Macrophages play critical roles in immunity to pathogens, tissue development, homeostasis and tissue repair. These cells are also primary targets for replication of viruses such as African swine fever virus, classical swine fever virus, and porcine respiratory and reproductive syndrome virus, which can cause huge economic losses to the pig industry. In this article, we review the current status of knowledge on porcine macrophages, starting by reviewing the markers available for their phenotypical characterization and following with the characteristics of the main macrophage populations described in different organs, as well as the effect of polarization conditions on their phenotype and function. We will also review available cell lines suitable for studies on the biology of porcine macrophages and their interaction with pathogens.

RESUMO

Erwinia amylovora, the bacterial species responsible for fire blight, causes major economic losses in pome fruit crops worldwide. Chemical control is not always effective and poses a serious threat to the environment and human health. Social demands for eco-sustainable and safe control methods make it necessary to search for new biocontrol strategies such as those based on antagonists. A bacterial collection from different fire blight-free Mediterranean environments was tested for antagonistic activity against Spanish strains of E. amylovora. Antagonistic assays were carried out in vitro in culture medium and ex vivo in immature loquat and pear fruits. Results revealed that 12% of the 82 bacterial isolates tested were able to inhibit the growth of several strains of the pathogen. Some of the isolates also maintained their antagonistic activity even after chloroform inactivation. Selected isolates were further tested ex vivo, with several of them being able to delay and/or reduce fire blight symptom severity in both loquats and pears and having activity against some E. amylovora strains. The isolates showing the best antagonism also produced different hydrolases linked to biocontrol (protease, lipase, amylase, and/or DNAse) and were able to fix molecular nitrogen. Based on this additional characterization, four biocontrol strain candidates were further selected and identified using MALDI-TOF MS. Three of them were Gram-positive bacteria belonging to Bacillus and Paenarthrobacter genera, and the fourth was a Pseudomonas strain. Results provide promising prospects for an improvement in the biological control strategies against fire blight disease.

RESUMO

Collective actions occur all around the world and, in the last few years, even more frequently. Previous literature has mainly focused on the antecedents of collective actions, but less attention has been given to the consequences of participating in collective action. Moreover, it is still an open question how the consequences of collective action might differ, depending on whether the actions are perceived to succeed or fail. In two studies we seek to address this gap using innovative experimental studies. In Study 1 (N = 368) we manipulated the perceptions of success and failure of a collective action in the context of a real social movement, the Chilean student movement from last decade. In Study 2 (N = 169), in addition to manipulating the outcome, we manipulated actual participation, using a mock environmental organization aiming to create awareness in authorities, to test the causal effect of both participation and success/failure on empowerment, group efficacy, and intentions of future involvement in normative and non-normative collective actions. Results show that current and past participation predict overall participation in the future, however, in Study 2 the manipulated participation was associated with having less intentions of participating in the future. In both studies, perception of success increases group efficacy. In Study 1, we found that when facing failure, participants increase their willingness to participate more in the future as opposed to non-participants that actually decrease theirs. In Study 2, however, failure increases the perception of efficacy for those with a history of non-normative participation. Altogether these results highlight the moderating role of the outcome of collective action to understand the effect of participation on future participation. We discuss these results in light of the methodological innovation and the real world setting in which our studies were conducted.

RESUMO

Ralstonia solanacearum is the causal agent of bacterial wilt, one of the most destructive diseases of solanaceous plants, affecting staple crops worldwide. The bacterium survives in water, soil, and other reservoirs, and is difficult to control. In this sense, the use of three specific lytic R. solanacearum bacteriophages was recently patented for bacterial wilt biocontrol in environmental water and in plants. To optimize their applications, the phages and the bacterium need to be accurately monitored and quantified, which is laborious and time-consuming with biological methods. In this work, primers and TaqMan probes were designed, and duplex and multiplex real-time quantitative PCR (qPCR) protocols were developed and optimized for the simultaneous quantification of R. solanacearum and their phages. The quantification range was established from 108 to 10 PFU/mL for the phages and from 108 to 102 CFU/mL for R. solanacearum. Additionally, the multiplex qPCR protocol was validated for the detection and quantification of the phages with a limit ranging from 102 targets/mL in water and plant extracts to 103 targets/g in soil, and the target bacterium with a limit ranging from 103 targets/mL in water and plant extracts to 104 targets/g in soil, using direct methods of sample preparation.

RESUMO

How do global citizens respond to a global health emergency? The present research examined the association between global citizen identification and prosociality using two cross-national datasets-the World Values Survey (Study 1, N = 93,338 from 60 countries and regions) and data collected in 11 countries at the start of the COVID-19 pandemic (Study 2, N = 5,427). Results showed that individuals who identified more strongly as global citizens reported greater prosociality both generally (Study 1) and more specifically in the COVID-19 global health emergency (Study 2). Notably, global citizen identification was a stronger predictor of prosociality in response to COVID-19 than national identification (Study 2). Moreover, analyses revealed that shared ingroup identity accounted for the positive association between global citizen identification and prosociality (Study 2). Overall, these findings highlight global citizenship as a unique and promising direction in promoting prosociality and solidarity, especially in the fight against COVID-19.

RESUMO

BACKGROUND: Current evidence supports the efficacy of prolonged dual antiplatelet treatment (DAPT) for patients at high-ischemic risk and low bleeding risk as well as the efficacy and safety of short DAPT in high-bleeding risk (HBR) patients. METHODS: We evaluated patterns of DAPT candidates in all patients discharged in 2 hospitals after an acute coronary syndrome (ACS). Patients categorized in 3 groups: 1) short-DAPT candidates if they met 1 major o 2 minor criteria for HBR, by the 2019 ARC-HBR criteria; 2) prolonged-DAPT candidates if were not HBR and had recurrent ACS, complex percutaneous coronary interventions or diabetes; 3) standard 12 months DAPT if were not include in the previous 2 groups. Major bleeding (MB) was registered according to 3 or 5 of the BARC consortium definitions. RESULTS: We included 8252 patients and 3215 (39 %) were candidates for abbreviated DAPT, 3119 (37.8 %) for prolonged DAPT, and 1918 (23.2 %) for 12 m DAPT. Relevant differences were observed between the 3 categories beyond the bleeding risk. Median follow-up was 57 months. Multivariate analysis identified higher risk of all-cause mortality (HR: 1.96 95 % CI 1.45-2.67; p < 0.001), cardiovascular mortality (HR: 2.10 95 % CI 1.39-3.19; p < 0.011), MACE (HR: 1.69 95 % 1.50-2.02; p < 0.001) and MB (sHR: 3.41 95 % CI 1.45-8.02; p = 0.005) in candidates to short DAPT. Candidates to prolonged DAPT had higher risk of MACE (HR: 1.17 95 % CI 1.02-1.35; p = 0.027). CONCLUSIONS: Almost two thirds of patients discharged after an ACS would be candidates for short or prolonged DAPT and these patients are at higher risk of MACE and mortality.

RESUMO

BACKGROUND: Remnant cholesterol has been identified as one of leading lipid values associated with the incidence of coronary heart disease. There is scarce evidence on its distribution and prognostic value in acute coronary syndrome (ACS) patients. METHODS AND RESULTS: We included all consecutive patients admitted for ACS in two different centres. Remnant cholesterol was calculated by the equation: total cholesterol minus LDL cholesterol minus HDL cholesterol, and values ≥30 were considered high. Among the 7479 patients, median remnant cholesterol level was 28 mg/dL (21-39), and 3429 (45.85%) patients had levels ≥30 mg/dL. Age (r: -0.29) and body mass index (r: 0.44) were the variables more strongly correlated. At any given age, patients with overweigh or obesity had higher levels. In-hospital mortality was 3.75% (280 patients). Remnant cholesterol was not associated to higher in-hospital mortality risk (odds ratio: 0.89; P = 0.21). After discharge (median follow-up of 57 months), an independent and linear risk of all-cause mortality and heart failure (HF) associated to cholesterol remnant levels was observed. Remnant cholesterol levels >60 mg/dL were associated to higher risk of mortality [hazard ratio (HR): 1.49 95% CI 1.08-2.06; P = 0.016], cardiovascular mortality (HR: 1.49 95% CI 1.08-2.06; P = 0.016), and HF re-admission (sub-HR: 1.55 95% CI 1.14-2.11; P = 0.005). CONCLUSIONS: Elevated remnant cholesterol is highly prevalent in patients admitted for ACS and is inversely correlated with age and positively with body mass index. Remnant cholesterol levels were not associated to higher in-hospital mortality risk, but they were associated with higher long-term risk of mortality and HF.


Elevated remnant cholesterol is highly prevalent in patients admitted for ACS and is related to body mass index and negatively with age. Remnant cholesterol it is not associated to higher in-hospital mortality risk, but it confers higher long-term risk of mortality and heart failure.

RESUMO

Progressive multifocal leukoencephalopathy (PML) is a demyelinating central nervous system disease infection by JC virus (JCV) in patients with a significant decline in cellular immunity. No specific treatment has demonstrated efficacy, and the disease progresses to death in most patients. Recent findings have shown stabilization or improvement of PML lesions after treatment with checkpoint inhibitors (CPI) based on immune reconstitution. Nevertheless, immunotherapy may specifically cause autoimmune diseases or may deteriorate pre-existing ones. We report a case of a patient under treatment for advanced ductal breast carcinoma and systemic sclerosis, who developed PML. The therapeutic approach included withdrawal of drugs with possible immunosuppressive effect and treatment with pembrolizumab. In the absence of reliable markers to predict CPIs response and a concern for an autoimmune worsening, immunotherapy was administered late in the course of the disease. Finally, she did not experience an autoimmune disease flare-up; however, pembrolizumab could not prevent disease progression. We believe that potential autoimmune complications should not delay treatment initiation with CPIs in PML.

RESUMO

Ralstonia solanacearum is a bacterial phytopathogen affecting staple crops, originally from tropical and subtropical areas, whose ability to survive in temperate environments is of concern under global warming. In this study, two R. solanacearum strains from either cold or warm habitats were stressed by simultaneous exposure to natural oligotrophy at low (4 °C), temperate (14 °C), or warm (24 °C) temperatures in environmental water. At 4 °C, the effect of temperature was higher than that of oligotrophy, since R. solanacearum went into a viable but non-culturable (VBNC) state, which proved to be dependent on water nutrient contents. Resuscitation was demonstrated in vitro and in planta. At 14 °C and 24 °C, the effect of oligotrophy was higher than that of temperature on R. solanacearum populations, displaying starvation-survival responses and morphological changes which were stronger at 24 °C. In tomato plants, starved, cold-induced VBNC, and/or resuscitated cells maintained virulence. The strains behaved similarly regardless of their cold or warm areas of origin. This work firstly describes the natural nutrient availability of environmental water favoring R. solanacearum survival, adaptations, and resuscitation in conditions that can be found in natural settings. These findings will contribute to anticipate the ability of R. solanacearum to spread, establish, and induce disease in new geographical and climatic areas.

RESUMO

Cardiogenic shock (CS) is a condition associated with high morbidity and mortality. Our study aimed to perform a risk score for in-hospital mortality that allows for stratifying the risk of death in patients with CS.This is a retrospective analysis, which included 135 patients from a Spanish university hospital between 2011 and 2020. The Santiago Shock Score (S3) was created using clinical, analytical, and echocardiographic variables obtained at the time of admission.The in-hospital mortality rate was 41.5%, and acute coronary syndrome (ACS) was the responsible cause of shock in 60.7% of patients. Mitral regurgitation grade III-IV, age, ACS etiology, NT-proBNP, blood hemoglobin, and lactate at admission were included in the score. The S3 had good accuracy for predicting in-hospital mortality area under the receiver operating characteristic curve (AUC) 0.85 (95% confidence interval (CI) 0.78-0.90), higher than the AUC of the CardShock score, which was 0.74 (95% CI 0.66-0.83). Predictive power in a cohort of 131 patients with profound CS was similar to that of CardShock with an AUC of 0.601 (95% CI 0.496-0.706) versus an AUC of 0.558 (95% CI 0.453-0.664). Three risk categories were created according to the S3: low (scores 0-6), intermediate (scores 7-10), and high (scores 11-16) risks, with an observed mortality of 12.9%, 49.1%, and 87.5% respectively (P < 0.001).The S3 score had excellent predictive power for in-hospital mortality in patients with nonprofound CS. It could aid the initial risk stratification of patients and thus, guide treatment and clinical decision making in patients with CS.

RESUMO

The Zwolle risk score was designed to stratify in-hospital mortality risk of ST-elevation myocardial infarction (STEMI) patients treated with primary percutaneous coronary intervention (pPCI) and for decision-making in the unit where patients are admitted. We assessed the accuracy of Zwolle risk score for in-hospital mortality estimation compared with the GRACE score in all patients (n = 4446) admitted for STEMI in 3 university hospitals. Only one fourth of the patients were classified as high-risk by the Zwolle risk score vs 60% by the GRACE score. In-hospital mortality was 10.6%. A statistically significant increase in in-hospital mortality, adjusted by age, gender, and revascularization, was observed with both scores. The assessment of the optimal cut-off points verified the accuracy of Zwolle score ≥4 as optimal threshold for high-risk categorization. In contrast, GRACE score ≥140 had very low specificity as well as percentage of patients correctly classified; GRACE score ≥175 was fairly better. The reclassification index of the Zwolle score after applying the GRACE score was 35.5%. Selection of high-risk STEMI patients treated with pPCI based on the Zwolle risk score has higher specificity than the GRACE score and might be useful in clinical practice.

RESUMO

AIMS: e-consults are asynchronous, clinician-to-clinician exchanges that answer focused, non-urgent, patient-specific questions using the electronic medical record. We instituted an e-consultation programme (2013-2019) for all general practitioners (GPs) referrals to cardiologists that preceded patients' in-person consultations when considered. In our study, we aimed to analyse the clinical characteristics, 1 year prognosis and the prognostic determinants of patients with a previous diagnosis of HF referred for an e-consult, categorized by their previous HF-related hospitalization status (recent hospitalization, <1 year before; remote hospitalization, >1 year before or never been hospitalized because of HF), and to analyse the impact of reducing the time elapsed between e-consultation and response by the cardiologist in terms of prognosis. METHODS AND RESULTS: Epidemiological and clinical data were obtained from 4851 HF patients referred by GPs to the cardiology department for an e-consultation 2013 and 2020. The delay of time to e-consults were solved was 8.6 + 8.6 days with 84.3% solved in <14 days. For the 1 year prognosis evaluation after the e-consult were assessed the cardiovascular hospitalizations, HF-related hospitalizations, HF-related mortality, cardiovascular mortality, and all-cause mortality. Compared with the group without a previous hospitalization, patients with recent and remote HF hospitalization were at higher risk of a new HF-related hospitalization (OR: 19.41 [95% CI: 12.95-29.11]; OR: 8.44 [95% CI: 5.14-13.87], respectively), HF-related mortality (OR: 2.47 [95% CI: 1.43-4.27]; OR: 1.25 [95% CI: 0.51-3.06], respectively), as well as cardiovascular hospitalizations and mortality and all-cause mortality. Reduction in the time elapsed because e-consultation was solved was associated with lower risk of HF-related mortality (OR: 0.94 [95% CI: 0.89-0.99]), cardiovascular mortality (OR: 0.96 [95% CI: 0.93-0.98]), and all-cause mortality (OR: 0.98 [95% CI: 0.97-1.00]). CONCLUSIONS: A clinician-to-clinician e-consultation programme between GPs and cardiologists in patients with HF allows to solve the demand of care in around 25% e-consults without an in-person consultation; the patients with a previous history of HF-related hospitalization showed a worse 1 year outcome. A reduction in the time elapsed because e-consultation was solved was associated with a mortality reduction.

RESUMO

While the relationship between loneliness and psychological distress is well documented, the mechanisms underlying this relationship are less clear. One factor known to be related to loneliness as well as psychological distress, is social support, with some studies suggesting that support-both received and provided-can serve as a mechanism to reduce the distress associated with loneliness. In this paper we examine the mediating role of both aspects of support in the relationship between loneliness and psychological distress in the COVID-19 context. We used a multi-country dataset collected at two timepoints during the pandemic; the first during the early stages (N = 6,842, 11 countries) and the second collected for a subset of countries (N = 1,299, 3 countries) 3 months later. Across all eleven countries, results revealed significant positive associations between loneliness and distress. Furthermore, using longitudinal data, we investigated the directionality of this relationship and found that increased loneliness over time was associated with increased psychological distress. The data also showed that both feeling unsupported and feeling unable to provide support to others mediated this relationship. These findings point to the need to facilitate people's ability to draw effective social support and help others-particularly at times when social connectedness is threatened-as a way of alleviating the psychological distress that commonly presents with loneliness.

RESUMO

BACKGROUND: The characteristics and outcome of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-positive patients with ST-Elevation Myocardial Infarction (STEMI) undergoing primary percutaneous coronary intervention (PPCI) are still poorly known. METHODS: The PANDEMIC study was an investigator-initiated, collaborative, individual patient data (IPD) meta-analysis of registry-based studies. MEDLINE, ScienceDirect, Web of Sciences, and SCOPUS were searched to identify all registry-based studies describing the characteristics and outcome of SARS-CoV-2-positive STEMI patients undergoing PPCI. The control group consisted of SARS-CoV-2-negative STEMI patients undergoing PPCI in the same time period from the ISACS-STEMI COVID 19 registry. The primary outcome was in-hospital mortality; the secondary outcome was postprocedural reperfusion assessed by TIMI flow. RESULTS: Of 8 registry-based studies identified, IPD were obtained from 6 studies including 941 SARS-CoV-2-positive patients; the control group included 2005 SARS-CoV-2-negative patients. SARS-CoV-2-positive patients showed a significantly higher in-hospital mortality (p < 0.001) and worse postprocedural TIMI flow (<3, p < 0.001) compared with SARS-CoV-2-negative subjects. The increased risk for SARS-CoV-2-positive patients was significantly higher in males compared to females for both the primary (pinteraction = 0.001) and secondary outcome (pinteraction = 0.023). In SARS-CoV-2-positive patients, age ≥ 75 years (OR = 5.72; 95%CI: 1.77-18.5), impaired postprocedural TIMI flow (OR = 11.72; 95%CI: 2.64-52.10), and cardiogenic shock at presentation (OR = 11.02; 95%CI: 2.84-42.80) were independent predictors of mortality. CONCLUSIONS: In STEMI patients undergoing PPCI, SARS-CoV-2 positivity is independently associated with impaired reperfusion and with a higher risk of in-hospital mortality, especially among male patients. Age ≥ 75 years, cardiogenic shock, and impaired postprocedural TIMI flow independently predict mortality in this high-risk population.

RESUMO

Even though formal processes (i.e., gender quotes) are necessary to achieve gender justice, attitudinal changes (i.e., support of egalitarian social norms) are also essential. The endorsement of sexism and gender stereotypes perpetuate inequality on a daily basis, and can be seen as barriers that prevent societies from reaching social justice. Therefore, changing sexist social norms can be understood as a fundamental step in accomplishing gender justice. With the aim of studying Chileans' sexist norms, we conducted a survey with a representative sample (N = 490) exploring levels of sexism and gender stereotypes, as well as support for the feminist movement. Using Latent Profile Analysis, we identified four groups of citizens: (1) a first group that shows high levels of sexism and low support for the feminist movement (9%); (2) a second group, with low levels of sexism and high support for the feminist movement (20%); (3) a third group with high levels of sexism and high support for the feminist movement (65%); and (4) a fourth group with mid-levels of sexism and support of the feminist movement (6%). We called these groups the Sexist, Feminist, Inconsistent, and Moderate Group, respectively. The four groups showed similar high endorsement of gender stereotypes. These results are twofold. First, they hint that although nowadays gender equality seems to be generally accepted, this coexists with a high prevalence of sexist social norms, represented by the inconsistent group being the most prevalent. Second, gender stereotypes are still deeply rooted in Chilean culture, surprisingly even among feminist citizens.

RESUMO

BACKGROUND: Severe tricuspid regurgitation (TR) is frequently associated with significant morbidity and mortality; such patients are often deemed to be at high surgical risk. Heterotopic bicaval stenting is an emerging, attractive transcatheter solution for these patients. OBJECTIVES: The aim of this study was to evaluate the 30-day safety and 6-month efficacy outcomes of specifically designed bioprosthetic valves for the superior and inferior vena cava. METHODS: TRICUS EURO (Safety and Efficacy of the TricValve® Transcatheter Bicaval Valves System in the Superior and Inferior Vena Cava in Patients With Severe Tricuspid Regurgitation) is a nonblinded, nonrandomized, single-arm, multicenter, prospective trial that enrolled patients from 12 European centers between December 2019 and February 2021. High-risk individuals with severe symptomatic TR despite optimal medical therapy were included. The primary endpoint was quality-of-life (QOL) improvement measured by Kansas City Cardiomyopathy Questionnaire score and New York Heart Association (NYHA) functional class improvement at 6-month follow-up. RESULTS: Thirty-five patients (mean age 76 ± 6.8 years, 83% women) were treated using the TricValve system. All patients at baseline were in NYHA functional class III or IV. At 30 days, procedural success was 94%, with no procedural deaths or conversions to surgery. A significant increase in QOL at 6 months follow-up was observed (baseline and 6-month Kansas City Cardiomyopathy Questionnaire scores 42.01 ± 22.3 and 59.7 ± 23.6, respectively; P = 0.004), correlating with a significant improvement in NYHA functional class, with 79.4% of patients noted to be in functional class I or II at 6 months (P = 0.0006). The rates of 6-month all-cause mortality and heart failure hospitalization were 8.5% and 20%, respectively. CONCLUSIONS: The dedicated bicaval system for treating severe symptomatic TR was associated with a high procedural success rate and significant improvements in both QOL and functional classification at 6 months follow-up.

RESUMO

BACKGROUND: Renal dysfunction in patients with ST-elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (pPCI) indicates a poor long-term prognosis. However, the prognostic value of the improvement or stabilisation of renal function during follow-up has not yet been assessed. This study aimed to investigate the long-term predictive impact of the improvement or stabilisation of renal function after one year of follow-up in patients with STEMI undergoing pPCI with renal dysfunction at discharge. METHODS: This prospective, single-centre cohort study included 2170 consecutive patients with STEMI who underwent pPCI. The glomerular filtration rate (GFR) was determined at hospital discharge and one-year follow-up. The median clinical follow-up was 72 months. RESULTS: Among the 2004 patients, 393 (19.6%) had a GFR <60 ml/min, and 1611 (80.4%) had a GFR ≥ 60 ml/min at discharge. Among patients with GFR <60 ml/min, data at one-year follow-up were available for 342. Of these patients, 127 (32%) showed improvement in renal function (defined as improvement in the Kidney Disease Improving Global Outcomes (KDIGO) chronic kidney disease (CKD) classification), 47 (12%) showed worsening of renal function (defined as worsening of the KDIGO CKD classification), and 168 (43%) showed no category changes. Improvement or stabilisation of GFR at one year of follow-up was associated with a reduction of major adverse cardiovascular events (MACE) [HR 0.51, 95% CI: 0.35-0.75, p = 0.001] and all-cause mortality [HR 0.54, 95% CI: 0.34-0.84, p = 0.007] during follow-up. CONCLUSIONS: The improvement or stabilisation of renal function at one-year follow-up in patients with STEMI and renal dysfunction is associated with a better long-term prognosis.
