RESUMO

Introducción y objetivos: La información sobre pacientes con fisiología univentricular (FU) y flujo pulmonar restrictivo no sometidos a cirugía de Fontan es escasa. El objetivo de este estudio es comparar la supervivencia y los eventos cardiovasculares en estos pacientes según el tipo de paliación.MétodosLos datos de pacientes con FU se obtuvieron de las bases de datos de 7 centros con unidades de cardiopatías congénitas del adulto. Se excluyó a los pacientes que completaron la circulación de Fontan o desarrollaron un síndrome de Eisenmenger. Se crearon 3 grupos según la fuente de flujo pulmonar: G1, flujo anterógrado pulmonar restrictivo; G2, shunt cavopulmonar, y G3, shunt aortopulmonar±shunt cavopulmonar. El objetivo principal fue la muerte.ResultadosSe identificó a 120 pacientes. La media de edad en la primera visita fue 32,2 años. El seguimiento medio fue de 7,1 años. Se asignó a 55 pacientes (45,8%) al G1, 30 (25%) al G2 y 35 (29,2%) al G3. Los pacientes del G3 tenían peores función renal, clase funcional y fracción de eyección en la primera visita y mostraron una disminución más marcada de la fracción de eyección durante el seguimiento, especialmente en comparación con el G1. Veinticuatro pacientes (20%) fallecieron, 38 (31,7%) ingresaron por insuficiencia cardiaca y 21 (17,5%) presentaron aleteo/fibrilación auricular durante el seguimiento. Estos eventos fueron más frecuentes en el G3 y al compararlos con los del G1 se encontraron diferencias significativas en muerte (HR=2,9; IC95%, 1,14-7,37; p=0,026) y aleteo/fibrilación auricular (HR=2,9; IC95%, 1,11-7,68; p=0,037).ConclusionesEl tipo de paliación de los pacientes con FU y flujo pulmonar restrictivo no sometidos a cirugía de Fontan identifica distintos perfiles. Los pacientes paliados con derivaciones aortopulmonares presentan un peor pronóstico, con más morbilidad y mortalidad. (AU)


Introduction and objectives: There is scarce information on patients with single ventricle physiology (SVP) and restricted pulmonary flow not undergoing Fontan circulation. This study aimed to compare survival and cardiovascular events in these patients according to the type of palliation.MethodsSVP patient data were obtained from the databases of the adult congenital heart disease units of 7 centers. Patients completing Fontan circulation or developing Eisenmenger syndrome were excluded. Three groups were created according to the source of pulmonary flow: G1 (restrictive pulmonary forward flow), G2 (cavopulmonary shunt), and G3 (aortopulmonary shunts±cavopulmonary shunt). The primary endpoint was death.ResultsWe identified 120 patients. Mean age at the first visit was 32.2 years. Mean follow-up was 7.1 years. Fifty-five patients (45.8%) were assigned to G1, 30 (25%) to G2, and 35 (29.2%) to G3. Patients in G3 had worse renal function, functional class, and ejection fraction at the first visit and a more marked ejection fraction decline during follow-up, especially when compared with G1. Twenty-four patients (20%) died, 38 (31.7%) were admitted for heart failure, and 21 (17.5%) had atrial flutter/fibrillation during follow-up. These events were more frequent in G3 and significant differences were found compared with G1 in terms of death (HR, 2.9; 95%CI, 1.14-7.37; P=.026) and atrial flutter/fibrillation (HR, 2.9; 95%CI, 1.11-7.68; P=.037).ConclusionsThe type of palliation in patients with SVP and restricted pulmonary flow not undergoing Fontan palliation identifies distinct profiles. Patients palliated with aortopulmonary shunts have an overall worse prognosis with higher morbidity and mortality. (AU)

RESUMO

Phosphatidylinositol-3,4,5-triphosphate (PIP3) is a lipidic second messenger present at very low concentrations in resting normal cells. PIP3 levels, though, increase quickly and transiently after growth factor addition, upon activation of phosphatidylinositol 3-kinase (PI3-kinase). PIP3 is required for the activation of intracellular signaling pathways that induce cell proliferation, cell migration, and survival. Given the critical role of this second messenger for cellular responses, PIP3 levels must be tightly regulated. The lipid phosphatase PTEN (phosphatase and tensin-homolog in chromosome 10) is the phosphatase responsible for PIP3 dephosphorylation to PIP2. PTEN tumor suppressor is frequently inactivated in endometrium and prostate carcinomas, and also in glioblastoma, illustrating the contribution of elevated PIP3 levels for cancer development. PTEN biological activity can be modulated by heterozygous gene loss, gene mutation, and epigenetic or transcriptional alterations. In addition, PTEN can also be regulated by post-translational modifications. Acetylation, oxidation, phosphorylation, sumoylation, and ubiquitination can alter PTEN stability, cellular localization, or activity, highlighting the complexity of PTEN regulation. While current strategies to treat tumors exhibiting a deregulated PI3-kinase/PTEN axis have focused on PI3-kinase inhibition, a better understanding of PTEN post-translational modifications could provide new therapeutic strategies to restore PTEN action in PIP3-dependent tumors.

RESUMO

INTRODUCTION: The presence of lymph nodes metastasis in papillary thyroid cancer (PTC) modifies the type of surgical resection as well as the indication of the treatment with I131 in the postoperative period. This therapeutic approach is based on the results of the diagnostic tests, like the cervical ultrasonography. Currently other methods of diagnostic are tested as selective sentinel lymph node biopsy (SLNB). It can complement to the ultrasound results. The aim was to validate the SLNB for use in the diagnosis of lymph node metastasis by papillary thyroid cancer. METHODS: Observational prospective cohort study of 55 patients who underwent PTC without suspicion of lymph node involvement clinical or radiological, since February 2012 through February 2015, with a follow-up between 6 and 8 years. It was used 99Tc with intratumoral nanocoloid and a portable tube of the gamma camera for the detection of the sentinel node (SN). VARIABLES: age, gender, histological, analytical and preoperative and postoperative staging. The sensitivity, specificity and predictive values of technique was calculated. The validation was determined by calculating the detectability and the false negative results of the test. RESULTS: 53 of the 55 patients (96,36%) there was the SN detection. The FN were 4 patients (7,5%). Of the rest, after applying the SLNB, 24 (48,9%) were kept as N0, 14 (28,5%) became N1a and 11 (22,4%) were classified as N1b. The differences observed in the study were significant (P < ,05). The sensitivity was 86,21%, the specificity of 100%, the PPV was 100% and the NPV of 85.71%. The diagnostic accuracy of 92,45%. CONCLUSION: The SLNB is a valid technique for use in patients suffering from papillary thyroid cancer with a high diagnostic accuracy.

RESUMO

Background: The outcomes of trapeziectomy with ligament reconstruction and tendon interposition (LRTI) compared to the trapeziectomy (T) alone or in combination with tendon interposition (TIA) in the treatment of osteoarthritis (OA) of the carpometacarpal joint (CMCJ) of the thumb are still debated. The aim of this study is to conduct a meta-analysis to determine whether the outcomes of LRTI were better compared to T or TIA. Methods: A meta-analysis of randomised trials that included the outcomes of patients with thumb CMCJ OA that underwent LRTI, T or TIA with at least 1 year follow-up. The outcomes included number of patients with pain 1 year after surgery (NPP), Visual Analog Scale for Pain (VAS Pain), key pinch strength, patient reported outcome measurements (PROMs) and number of adverse effect (AEs). The effect was assessed using mean difference for quantitative variables (VAS pain and key pinch), standardised mean difference for PROMs and relative risk for binary variables (NPP and AEs). Results: Seven studies met the inclusion criteria (857 participants: 438 LRTI vs 419 T/TIA). We did not find significant differences between LRTI and T/TIA in NPP, VAS pain, key pinch at 1 year and 5 years or more, PROMs, and AEs at 1 year and at 5 years or more after surgery. Conclusions: The outcomes of LRTI are not superior to T or TIA in the treatment of OA of the thumb CMCJ. Level of Evidence: Level I (Therapeutic).

RESUMO

Introducción y objetivos: El control glucémico postprandial es fundamental para conseguir los objetivos metabólicos en pacientes con diabetes mellitus tipo 1 (DM1). La nueva insulina faster aspart presenta un perfil farmacológico caracterizado por una absorción e inicio de acción más rápidos, mayor disponibilidad precoz y menor incremento de la glucosa postprandial. El objetivo principal del estudio fue analizar su eficacia en pacientes con DM1 tratados con un sistema integrado.Pacientes y métodos: Estudio analítico, longitudinal, prospectivo y multicéntrico, evaluando el empleo de faster aspart durante tres meses en pacientes en edad pediátrica con DM1 con sistema integrado MiniMed640G® tratados previamente con insulina aspart. Al inicio y final del estudio se analizaron para posterior comparación: glucosa media, porcentajes de tiempo en objetivo, tiempo en hipoglucemia e hiperglucemia, área bajo la curva (AUC) < 70 y > 180 mg/dL, glucosa media pre y postprandial en comidas principales, necesidades diarias de insulina, porcentaje basal/bolo y HbA1c. Se registraron complicaciones agudas y eventos adversos, y se evaluó grado de satisfacción mediante encuesta.Resultados: Se incluyeron 31 pacientes de 13,49 ± 2,42 años de edad con DM1 de 7,0 ± 3,67 años de evolución. Faster aspart se asoció con menor porcentaje de tiempo en hiperglucemia > 180 mg/dL (25,8 ± 11,3 vs. 22,4 ± 9,5; p = 0,011) y > 250 mg/dL (5,2 ± 4,9 vs. 4,0 ± 3,6; p = 0,04) y AUC > 180 mg/dL (10,8 ± 6,5 vs. 9,3 ± 6,1; p = 0,03), incrementándose el tiempo en objetivo (71,4 ± 10,0 vs. 74,3 ± 9,2; p = 0,03) sin aumentar hipoglucemias. Las necesidades de insulina, porcentajes basal/bolo y HbA1c no se modificaron significativamente. Faster aspart fue bien tolerada y valorada por los participantes.Conclusiones: Faster aspart consigue un mejor control glucémico, aumentando el tiempo de glucosa en objetivo en niños y adolescentes con DM1 en tratamiento con un sistema integrado.

The new «faster aspart» insulin has a pharmacological profile noted for its faster absorption and onset of action, and increased early availability, resulting in improved blood glucose control after meals. The main objective of the study was to analyse the efficacy of «faster aspart» vs. «insulin aspart» in children and adolescents with DM1 on sensor-augmented pump treatment.Patients and methods: Multicentre, longitudinal and prospective analytical trial evaluating the use of faster aspart insulin for three months in children with T1DM with MiniMed640G® sensor-augmented pumps previously treated with aspart insulin. At the beginning and end of the study the following variables were analysed for subsequent comparison: mean sensor glucose, percentage of time in range, hypoglycaemia and hyperglycaemia, area under the curve (AUC) < 70 and > 180 mg/dL, mean sensor glucose pre and postprandial in main meals, daily insulin requirements, basal/bolus percentage, and HbA1c. Acute complications, adverse events and satisfaction survey were assessed.Results: The study included 31 patients with a mean of 13.49 ± 2.42 years of age and with T1DM of 7.0 ± 3.67 years of onset. The use of faster aspart was associated with lower time in hyperglycaemia > 180 mg/dL (25.8 ± 11.3 vs. 22.4 ± 9.5; p = 0.011) and > 250 mg/dL (5.2 ± 4.9 vs. 4.0 ± 3.6; p = 0.04), lower AUC > 180 mg/dL (10.8 ± 6.5 vs. 9.3 ± 6.1; p = 0.03), and increased time in range (71.4 ± 10.0 vs. 74.3 ± 9.2; p = 0.03). No significant changes in hypoglycaemia, HbA1c, insulin requirements, and basal/bolus percentages were detected. Faster aspart was safe and well-evaluated by patients and caregivers.Conclusions: Faster aspart achieves better glycaemic control by increasing glucose time in range in children and adolescents with T1DM on treatment with sensor-augmented pumps.

RESUMO

BACKGROUND: Scimitar syndrome is a rare congenital disease characterized by partial or total anomalous pulmonary venous return from the right lung into the systemic venous system, and accounts for 0.5-2% of all congenital heart disease. Severe forms of the disease are diagnosed in childhood. However, because of the benign form of the syndrome in adults, many are asymptomatic, or present only mild symptoms including exertional dyspnoea, arrhythmias, and respiratory infections. We report an atypical presentation with hepatomegaly. CASE SUMMARY: A 24-year-old woman was evaluated for abdominal discomfort. Physical examination revealed a remarkable hepatomegaly. Chest X-ray revealed dextroversion, enlargement of the right cavities, and a curvilinear opacity known as 'scimitar sign'. A transthoracic echocardiography demonstrated right ventricular dilation and a venous collector draining into right suprahepatic vein, which was severely dilated, with large hepatomegaly. Scimitar syndrome was confirmed by magnetic resonance imaging (MRI). Therefore, the patient underwent surgery, redirecting the pulmonary venous return to left atrium. Three months later, the patient remained asymptomatic and both the hepatomegaly and the right chamber volumes normalized. DISCUSSION: Abdominal discomfort, as in our clinical case, is a highly atypical presentation of scimitar syndrome. It is important for physicians to be aware that diagnostic suspicion can be established from a chest X-ray, on which the scimitar sign can be distinguished in many cases. The diagnosis must be confirmed with other imaging modalities, such as echocardiography, MRI, or computed tomography. Corrective surgery may relieve the symptoms related to liver congestion at follow-up.

INTRODUCTION: The presence of lymph nodes metastasis in papillary thyroid cancer modifies the type of surgical resection as well as the indication of the treatment with 131I in the postoperative period. This therapeutic approach is based on the results of the diagnostic tests, like the cervical ultrasonography. Currently other methods of diagnostic are tested as selective sentinel lymph node biopsy (SLNB). It can complement to the ultrasound results. The aim was to validate the SLNB for use in the diagnosis of lymph node metastasis by papillary thyroid cancer. METHODS: Observational prospective cohort study of 55 patients who underwent papillary thyroid cancer without suspicion of lymph node involvement clinical or radiological, since February 2012 through February 2015, with a follow-up between 6 and 8 years. It was used 99Tc with intratumoral nanocoloid and a portable tube of the gamma camera for the detection of the sentinel node. VARIABLES: age, gender, histological, analytical and preoperative and postoperative staging. The sensitivity, specificity and predictive values of technique was calculated. The validation was determined by calculating the detectability and the false negative results of the test. RESULTS: In 53 of the 55 patients (96.36%) there was the sentinel node detection. The false negative were 4 patients (7.5%). Of the rest, after applying the SLNB, 24 (48.9%) were kept as N0, 14 (28.5%) became N1a and 11 (22.4%) were classified as N1b. The differences observed in the study were significant (P<.05). The sensitivity was 86.21%, the specificity of 100%, the PPV was 100% and the NPV of 85.71%. The diagnostic accuracy was 92.45%. CONCLUSIONS: The SLNB is a valid technique for use in patients suffering from papillary thyroid cancer with a high diagnostic accuracy.

RESUMO

BACKGROUND: Atrial tachyarrhythmias (ATs) represent the major late complications of congenital heart diseases (CHDs) following surgery. Little is known about the association between echocardiographic parameters and AT. AIMS: This study aimed to investigate a potential correlation among clinical, echocardiographic, and electrocardiographic parameters and AT as well as to analyze outcomes in adults with CHD and AT. METHODS: A retrospective case­control study was performed in adults with CHD. We included 71 patients with AT and 71 control individuals matched by sex, age, and the type of CHD without AT, all from the same institute. Medical records, electrocardiograms, and echocardiograms were reviewed. Adverse cardiovascular events were recorded and defined as cardiovascular mortality, admission for heart failure, or stroke. The univariate and multivariate logistic regression analysis of possible risk factors and the Kaplan-Meier analysis of adverse cardiovascular events were performed. RESULTS: Subpulmonary ventricular systolic pressure≥40 mm Hg (hazard ratio [HR], 6.8; 95% CI, 2.4-18; P <0.001), right atrial dilatation≥21 cm2 (HR, 3.1; 95% CI, 1.2-7.6; P = 0.01), and significant tricuspid regurgitation (HR, 4; 95% CI, 1.3-10; P = 0.02) were identified as the main risk factors for AT. Patients with AT had worse outcomes, more frequently developed adverse cardiovascular events (86% vs 14%; P <0.01), and exhibited a 58% event­free survival rate compared with 98% of the patients without AT after 8 years of follow­up (log rank, 6.6; P = 0.01). CONCLUSIONS: Among patients with CHD, the main risk factors for AT include right atrial dilatation, high subpulmonary ventricular systolic pressure, and significant tricuspid regurgitation. The presence of AT may increase the risk of adverse cardiac events.

RESUMO

INTRODUCCIÓN Y OBJETIVOS: Analizar la estructura asistencial y las características clínicas de las cardiopatías congénitas del adulto en España. MÉTODOS: En 2014 se realizó una encuesta entre 32 centros que se clasificaron como nivel 1 o 2 en función de su estructura asistencial. En 2017 se realizó un registro clínico de todos los pacientes asistidos consecutivamente en cada centro durante un periodo de 2 meses. RESULTADOS: Un total de 31 centros (97%) respondieron la encuesta. Se excluyó a 7 por no disponer de consulta especializada. Hasta el año 2005 solo había 5 centros con dedicación específica, pero en 2014 había 10 centros de nivel 1 y 14 de nivel 2 con un total de 19.373 pacientes en seguimiento. La estructura institucional era completa en la mayoría de los centros, pero solo el 33% disponía de enfermería propia y el 29%, de unidad de transición estructurada. La actividad terapéutica específica supuso el 99 y el 91% de la publicada en los registros nacionales de cirugía y cateterismo terapéutico. Del total, el 44% de los pacientes tenían cardiopatía de complejidad moderada y el 24%, de gran complejidad. Aunque el 46% de los pacientes atendidos en centros de nivel 2 tenían cardiopatías simples, el 17% eran cardiopatías de gran complejidad. CONCLUSIONES: La estructura y la actividad de los centros españoles cumplen las recomendaciones internacionales y son comparables a las de otros países desarrollados. El espectro de cardiopatías en seguimiento muestra una concentración de lesiones de complejidad moderada y gran complejidad incluso en centros de nivel 2. Sería aconsejable reordenar el seguimiento de los pacientes en función de las recomendaciones internacionales


INTRODUCTION AND OBJECTIVES: To assess the structure of health care delivery and the clinical characteristics of adults with congenital heart disease (ACHD) attending specialized centers in Spain. METHODS: A survey was conducted among 32 Spanish centers in 2014. The centers were classified into 2 levels based on their resources. In 2017, a clinical dataset was collected of all consecutive patients attended for a 2-month period at these centers. RESULTS: A total of 31 centers (97%) completed the survey. Seven centers without specialized ACHD clinics were excluded from the analysis. In 2005, only 5 centers met the requirements for specific care. In 2014, there were 10 level 1 and 14 level 2 centers, with a total of 19 373 patients under follow-up. Health care structure was complete in most centers but only 33% had ACHD nurse specialists on staff and 29% had structured transition programs. Therapeutic procedures accounted for 99% and 91% of those reported by National Registries of Cardiac Surgery and Cardiac Catheterization, respectively. Among attended patients, 48% had moderately complex lesions and 24% had highly complex lesions. Although 46% of patients attending level 2 centers had simple lesions, 17% had complex lesions. CONCLUSIONS: The structure for ACHD health care delivery in Spain complies with international recommendations and is similar to that of other developed countries. Congenital heart diseases under specialized care consist mostly of moderately and highly complex lesions, even in level 2 centers. It would be desirable to reorganize patient follow-up according to international recommendations in clinical practice

RESUMO

Despite interest in phosphoinositide (PtdIns) kinases, such as PtdIns 3 kinases (PI3K), as targets for controlling plasma membrane PtdIns levels in disease, the PtdIns have another less well-known site of action in the cell nucleus.Recent studies show that PtdIns use a variety of strategies to alter DNA responses. Here, we provide an overview of these newly identified forms of gene expression control, which should be considered when studying the therapeutic use of PtdIns-directed compounds. As PI3K is one of the most important clinical targets in recent years, we will focus on two polyphosphoinositides, the PI3K substrate PtdIns(4,5)di-phosphate (PI4,5P2) and its product PtdIns(3,4,5)tri-phosphate (PI3,4,5P3).

RESUMO

BACKGROUND AND AIMS: Post-prandial glucose control is essential to achieve metabolic goals in patients with type 1 diabetes mellitus (T1DM). The new «faster aspart¼ insulin has a pharmacological profile noted for its faster absorption and onset of action, and increased early availability, resulting in improved blood glucose control after meals. The main objective of the study was to analyse the efficacy of «faster aspart¼ vs. «insulin aspart¼ in children and adolescents with DM1 on sensor-augmented pump treatment. PATIENTS AND METHODS: Multicentre, longitudinal and prospective analytical trial evaluating the use of faster aspart insulin for three months in children with T1DM with MiniMed640G® sensor-augmented pumps previously treated with aspart insulin. At the beginning and end of the study the following variables were analysed for subsequent comparison: mean sensor glucose, percentage of time in range, hypoglycaemia and hyperglycaemia, area under the curve (AUC) < 70 and > 180 mg/dL, mean sensor glucose pre and postprandial in main meals, daily insulin requirements, basal/bolus percentage, and HbA1c. Acute complications, adverse events and satisfaction survey were assessed. RESULTS: The study included 31 patients with a mean of 13.49 ± 2.42 years of age and with T1DM of 7.0 ± 3.67 years of onset. The use of faster aspart was associated with lower time in hyperglycaemia > 180 mg/dL (25.8 ± 11.3 vs. 22.4 ± 9.5; p = 0.011) and > 250 mg/dL (5.2 ± 4.9 vs. 4.0 ± 3.6; p = 0.04), lower AUC > 180 mg/dL (10.8 ± 6.5 vs. 9.3 ± 6.1; p = 0.03), and increased time in range (71.4 ± 10.0 vs. 74.3 ± 9.2; p = 0.03). No significant changes in hypoglycaemia, HbA1c, insulin requirements, and basal/bolus percentages were detected. Faster aspart was safe and well-evaluated by patients and caregivers. CONCLUSIONS: Faster aspart achieves better glycaemic control by increasing glucose time in range in children and adolescents with T1DM on treatment with sensor-augmented pumps.

RESUMO

BACKGROUND: Anomalous origin of the left coronary artery (LCA) from the pulmonary artery (ALCAPA) is an unusual congenital heart defect which affects approximately 1 in 300 000 live births and accounts for 0.5% of all congenital heart disease. Without surgical intervention, most patients die in infancy (nearly 90%). CASE SUMMARY: We present a rare case of an asymptomatic 67-year-old female. Transthoracic echocardiography demonstrated a dilated right coronary artery (RCA) and multiple collaterals. ALCAPA was confirmed by multidetector computed tomography. The left main artery was seen originating from the pulmonary artery and well-developed collaterals were visualized between the RCA and LCA. No areas of myocardial infarction were identified on cardiac magnetic resonance. Stress studies showed no inducible ischaemia. DISCUSSION: Our clinical case of an ALCAPA patient who survived and remained asymptomatic to their late 60's, highlights the importance of well-collateralized and pressurized coronary system to maintain adequate myocardial perfusion. Physicians should be aware of this congenital anomaly as appropriate early diagnosis is crucial to prevent irreversible myocardial damage, acute ischaemia, and arrhythmias, and can improve patient outcomes. Surgical treatment is suggested irrespective of symptomatology or the presence of inducible myocardial ischaemia.

RESUMO

Dysregulation of the PI3K/PTEN pathway is a frequent event in cancer, and PIK3CA and PTEN are the most commonly mutated genes after TP53. PIK3R1 is the predominant regulatory isoform of PI3K. PIK3R2 is an ubiquitous isoform that has been so far overlooked, but data from The Cancer Genome Atlas shows that increased expression of PIK3R2 is also frequent in cancer. In contrast to PIK3R1, which is a tumor-suppressor gene, PIK3R2 is an oncogene. We review here the opposing roles of PIK3R1 and PIK3R2 in cancer, the regulatory mechanisms that control PIK3R2 expression, and emerging therapeutic approaches targeting PIK3R2.

RESUMO

Leishmania spp. is a protozoan parasite that affects millions of people around the world. At present, there is no effective vaccine to prevent leishmaniases in humans. A major limitation in vaccine development is the lack of precise understanding of the particular immunological mechanisms that allow parasite survival in the host. The parasite-host cell interaction induces dramatic changes in transcriptome patterns in both organisms, therefore, a detailed analysis of gene expression in infected tissues will contribute to the evaluation of drug and vaccine candidates, the identification of potential biomarkers, and the understanding of the immunological pathways that lead to protection or progression of disease. In this large-scale analysis, differential expression of 112 immune-related genes has been analyzed using high-throughput qPCR in spleens of infected and naïve Balb/c mice at four different time points. This analysis revealed that early response against Leishmania infection is characterized by the upregulation of Th1 markers and M1-macrophage activation molecules such as Ifng, Stat1, Cxcl9, Cxcl10, Ccr5, Cxcr3, Xcl1, and Ccl3. This activation doesn't protect spleen from infection, since parasitic burden rises along time. This marked difference in gene expression between infected and control mice disappears during intermediate stages of infection, probably related to the strong anti-inflammatory and immunosuppresory signals that are activated early upon infection (Ctla4) or remain activated throughout the experiment (Il18bp). The overexpression of these Th1/M1 markers is restored later in the chronic phase (8 wpi), suggesting the generation of a classical "protective response" against leishmaniasis. Nonetheless, the parasitic burden rockets at this timepoint. This apparent contradiction can be explained by the generation of a regulatory immune response characterized by overexpression of Ifng, Tnfa, Il10, and downregulation Il4 that counteracts the Th1/M1 response. This large pool of data was also used to identify potential biomarkers of infection and parasitic burden in spleen, on the bases of two different regression models. Given the results, gene expression signature analysis appears as a useful tool to identify mechanisms involved in disease outcome and to establish a rational approach for the identification of potential biomarkers useful for monitoring disease progression, new therapies or vaccine development.

RESUMO

BACKGROUND: Atrial tachycardias (ATs) are a significant source of morbidity in adults with congenital heart disease (CHD). This study evaluates the incidence and clinical predictors of AT in a cohort of patients with CHD. METHODS AND RESULTS: We included 3311 adults (median age at entry 22.6 years, 50.6% males) with CHD (49% simple, 39% moderate, and 12% complex) prospectively followed up in a tertiary center for 37 607 person-years. Predictors of AT were identified by multivariable Cox regression analysis accounting for left truncation. An external validation was performed in a contemporary cohort of 1432 patients. Overall, 153 (4.6%) patients presented AT. AT burden was highest in complex CHD, such as single ventricle (22.8%) and d-transposition of the great arteries (22.1%). Hazard rates of AT across lifetime, age at presentation, and the time lapse between surgery and the first AT episode varied among the most common CHD. Independent risk factors for developing AT were univentricular physiology, previous intracardiac repair, systemic right ventricle, pulmonary hypertension, pulmonary regurgitation, pulmonary atrioventricular valve regurgitation, pulmonary and systemic ventricular dysfunction. At the age of 40 years, AT-free survival in patients with 0, 1, 2, and ≥3 risk factors was 100%, 94%, 76%, and 50%, respectively. These findings were confirmed in the validation cohort. CONCLUSIONS: Natural history of AT differed among the most common forms of CHD. Simple clinical parameters, easily obtained by noninvasive means, were independent predictors of AT in adults with CHD. Although risk was negligible in patients without any of these factors, their addition progressively increased AT burden.
