RESUMO

We introduce both conceptual and empirical findings arising from the amalgamation of a robotics cognitive architecture with an embedded physics simulator, aligning with the principles outlined in the intuitive physics literature. The employed robotic cognitive architecture, named CORTEX, leverages a highly efficient distributed working memory known as deep state representation. This working memory inherently encompasses a fundamental ontology, state persistency, geometric and logical relationships among elements, and tools for reading, updating, and reasoning about its contents. Our primary objective is to investigate the hypothesis that the integration of a physics simulator into the architecture streamlines the implementation of various functionalities that would otherwise necessitate extensive coding and debugging efforts. Furthermore, we categorize these enhanced functionalities into broad types based on the nature of the problems they address. These include addressing challenges related to occlusion, model-based perception, self-calibration, scene structural stability, and human activity interpretation. To demonstrate the outcomes of our experiments, we employ CoppeliaSim as the embedded simulator and both a Kinova Gen3 robotic arm and the Open-Manipulator-P as the real-world scenarios. Synchronization is maintained between the simulator and the stream of real events. Depending on the ongoing task, numerous queries are computed, and the results are projected into the working memory. Participating agents can then leverage this information to enhance overall performance.

RESUMO

The diagnostic process of familial hypercholesterolemia frequently involves the use of genetic studies. Patients are treated with lipid-lowering drugs, frequently statins. Although pharmacogenomic clinical practice guidelines focusing on genotype-based statin prescription have been published, their use in routine clinical practice remains very modest.We have implemented a new NGS strategy that combines a panel of genes related to familial hypercholesterolemia with genomic regions related to the pharmacogenomics of lipid-lowering drugs described in clinical practice guidelines and in EMA and FDA drug labels. A multidisciplinary team of doctors, biologists, and pharmacists creates a clinical report that provides diagnostic and therapeutic findings using a knowledge management and clinical decision support system, as well as an algorithm for treatment selection.For 12 months, a total of 483 genetic diagnostic studies for familial hypercholesterolemia were carried out, of which 221 (45.8%) requested a complementary pharmacogenomic test. Of these 221 patients, 66.5% were carriers of actionable variants in any of the studied pharmacogenomic pathways: 46.6% of patients in one pathway, 19.0% in two pathways, and 0.9% in three pathways. 45.7% of patients could have a response to atorvastatin different from that of the reference population, 45.7% for simvastatin and lovastatin, 29.0% for fluvastatin, and 6.7% patients for pitavastatin.This implementation approach facilitates the incorporation of pharmacogenomic studies in clinical care practice, it does not add complexity nor additional steps to laboratory processes, and improves the pharmacotherapeutic process of patients.

RESUMO

AIM: To determine periodontitis prevalence in patients with systemic lupus erythematosus (SLE) and to assess whether periodontitis in SLE patients is associated with a greater subclinical atherosclerosis. METHODS: An observational case-control study was conducted in SLE (cases) and patients without any rheumatic diseases (controls), matched for sex. Sociodemographic and cardiometabolic variables were gathered, and SLE activity was assessed through several indexes. Periodontal examination registered probing pocket depth, clinical attachment level, bleeding on probing, plaque index, and tooth loss. Subclinical atherosclerosis was assessed by measuring the carotid-femoral pulse wave velocity (PWV) by Doppler velocimetry, homocysteine levels, C-reactive protein (CRP), and erythrocyte sedimentation rate (ESR). Bivariate analyses and logistic regression were used to assess the association of any of the studied variables with SLE. RESULTS: Seventy-one cases and 72 controls were included in the study. Thirty-nine SLE patients (54.9%) were diagnosed with periodontitis, compared with 16 controls (22.2%). High levels of PWV (≥7.7 m/s, 75th percentile) were shown by 44.3% of the cases vs. 22.4% of the controls (p = .011). Among SLE patients, those with periodontitis showed higher PWV values (8.1 ± 1.52 vs. 7.16 ± 1.11 m/s, p = .006) and higher homeostasis model assessment index (indicative of insulin resistance) (1.7 ± 0.73 vs. 2.92 ± 3.05, p = .028) compared to those with periodontal health. Logistic regression showed that waist circumference (OR 1.06, 95% CI 1.01-1.12, p = .015); ESR (OR 1.09, 95% CI 1.03-1.16, p = .003); and bleeding on probing (OR 1.1, 95% CI 1.01-1.19, p = .018) were associated with the risk of SLE. CONCLUSION: Systemic lupus erythematosus patients showed a higher periodontitis percentage than controls. Higher PWV values were found in SLE patients with periodontitis, indicating a higher prevalence of subclinical atherosclerosis. Patients with higher gingival bleeding showed a higher risk of SLE.

RESUMO

The objective of this study was to determine clinical-epidemiological characteristics of the patients and the genetic characteristics of carbapenemase KPC-3-producing Klebsiella pneumoniae isolates belonging to sequence type ST258. The eligible study population was all patients with isolates detected between October 2015 and March 2017. Clinical-epidemiological and microbiological data were gathered on risk factors associated with infection by this clone. Antimicrobial susceptibility was determined using MicroScan system and diffusion in agar. Genes encoding carbapenemases were detected using PCR and Sanger sequencing. The sequence type was assigned by MLST, and the genetic relationship among clinical isolates was determined by pulsed field electrophoresis and by analysis of the genetic environment. The study included 23 individuals with isolates of KPC-3/ST258; the mean age was 77 year, and mean stay pre-isolation was 32 days; 81% received empirical antimicrobial treatment. Isolates were only susceptible to gentamicin (CIM ≤ 2 mg/L), tigecycline (CIM ≤ 1 mg/L), and colistin (CIM ≤ 2 mg/L). The isolates belonged to ST258, with five pulse types or subgroups. All isolates showed amplification of KPC, which was identified as KPC-3 variant. Gene blaKPC-3 was flanked by insertion sequences Kpn6 and Kpn7 within Tn4401 transposon isoform a. We report, for the first time in Spain, an 18-month outbreak by KPC-3-producing ST258 K. pneumoniae. Its acquisition was associated with a history of antimicrobial therapy, with three treatment options, and with high mortality. The detection of different pulse types is attributable to different introductions of the clone in our setting, supporting the need for multi-resistant isolate surveillance studies.

RESUMO

The advances of the Internet of Things, robotics, and Artificial Intelligence, to give just a few examples, allow us to imagine promising results in the development of smart buildings in the near future. In the particular case of elderly care, there are new solutions that integrate systems that monitor variables associated with the health of each user or systems that facilitate physical or cognitive rehabilitation. In all these solutions, it is clear that these new environments, usually called Ambient Assisted Living (AAL), configure a Cyber-Physical System (CPS) that connects information from the physical world to the cyber-world with the primary objective of adding more intelligence to these environments. This article presents a CPS-AAL for caregiving centers, with the main novelty that includes a Socially Assistive Robot (SAR). The CPS-AAL presented in this work uses a digital twin world with the information acquired by all devices. The basis of this digital twin world is the CORTEX cognitive architecture, a set of software agents interacting through a Deep State Representation (DSR) that stored the shared information between them. The proposal is evaluated in a simulated environment with two use cases requiring interaction between the sensors and the SAR in a simulated caregiving center.

RESUMO

This paper presents a method to reduce the time spent by a robot with cognitive abilities when looking for objects in unknown locations. It describes how machine learning techniques can be used to decide which places should be inspected first, based on images that the robot acquires passively. The proposal is composed of two concurrent processes. The first one uses the aforementioned images to generate a description of the types of objects found in each object container seen by the robot. This is done passively, regardless of the task being performed. The containers can be tables, boxes, shelves or any other kind of container of known shape whose contents can be seen from a distance. The second process uses the previously computed estimation of the contents of the containers to decide which is the most likely container having the object to be found. This second process is deliberative and takes place only when the robot needs to find an object, whether because it is explicitly asked to locate one or because it is needed as a step to fulfil the mission of the robot. Upon failure to guess the right container, the robot can continue making guesses until the object is found. Guesses are made based on the semantic distance between the object to find and the description of the types of the objects found in each object container. The paper provides quantitative results comparing the efficiency of the proposed method and two base approaches.

RESUMO

The Laboratory of the Neuropsychology and Cognitive Neurosciences Research Center (CINPSI Neurocog), located in the "Technological Park" building of the Catholic University of Maule (Universidad Católica del Maule, UCM) campus in Talca, Chile, has been established as "Psychology Lab" recently in July, 2016. Our lines of work include basic and applied research. Among the basic research, we study executive functions, decision-making, and spatial cognition. In the applied field, we have studied neuropsychological and neurobehavioral effects of pesticides exposure, among other interests. One of our aims is to develop collaboration both national and internationally. It is important to mention that to date there are only few psychology laboratories and research centers in Chile involved with the fields of neuropsychology and neurosciences. Thus, this scientific effort could be a groundbreaking initiative to develop specific knowledge in this area locally and interculturally through its international collaborations.

RESUMO

Every day, the emergency departments in our country receive a large number of patients that have thought about or attempted suicide. Unfortunately, these patients are very often reluctant to maintain a regular follow-up in mental health services. In this study we describe an original program to encourage assessment and treatment of suicidal patients, particularly when they receive medical treatment in public places. We summarize the application of the program and compare the results of a specific follow-up between two groups of patients: suicidal patients assessed by emergency services in public places and all other suicidal patients assessed in the emergency department of a tertiary hospital.

RESUMO

This paper presents a multi-sensor humanoid robotic head for human robot interaction. The design of the robotic head, Muecas, is based on ongoing research on the mechanisms of perception and imitation of human expressions and emotions. These mechanisms allow direct interaction between the robot and its human companion through the different natural language modalities: speech, body language and facial expressions. The robotic head has 12 degrees of freedom, in a human-like configuration, including eyes, eyebrows, mouth and neck, and has been designed and built entirely by IADeX (Engineering, Automation and Design of Extremadura) and RoboLab. A detailed description of its kinematics is provided along with the design of the most complex controllers. Muecas can be directly controlled by FACS (Facial Action Coding System), the de facto standard for facial expression recognition and synthesis. This feature facilitates its use by third party platforms and encourages the development of imitation and of goal-based systems. Imitation systems learn from the user, while goal-based ones use planning techniques to drive the user towards a final desired state. To show the flexibility and reliability of the robotic head, the paper presents a software architecture that is able to detect, recognize, classify and generate facial expressions in real time using FACS. This system has been implemented using the robotics framework, RoboComp, which provides hardware-independent access to the sensors in the head. Finally, the paper presents experimental results showing the real-time functioning of the whole system, including recognition and imitation of human facial expressions.

RESUMO

AIM: We aimed to describe clinical and genetic characteristics, lipid-lowering treatment and atherosclerotic cardiovascular disease (ASCVD) outcomes over a long-term follow-up in homozygous familial hypercholesterolemia (HoFH). METHODS: SAFEHEART (Spanish Familial Hypercholesterolaemia Cohort Study) is a long-term study in molecularly diagnosed FH. Data analyzed in HoFH were prospectively obtained from 2004 until 2022. ASCVD events, lipid profile and lipid-lowering treatment were determined. RESULTS: Thirty-nine HoFH patients were analyzed. The mean age was 42 ± 20 years and nineteen (49%) were women. Median follow-up was 11 years (IQR 6,18). Median age at genetic diagnosis was 24 years (IQR 8,42). At enrolment, 33% had ASCVD and 18% had aortic valve disease. Patients with new ASCVD events and aortic valve disease at follow-up were six (15%), and one (3%), respectively. Median untreated LDL-C levels were 555 mg/dL (IQ 413,800), and median LDL-C levels at last follow-up was 122 mg/dL (IQR 91,172). Most patients (92%) were on high intensity statins and ezetimibe, 28% with PCSK9i, 26% with lomitapide, and 23% with lipoprotein-apheresis. Fourteen patients (36%) attained an LDL-C level below 100 mg/dL, and 10% attained an LDL-C below 70 mg/dL in secondary prevention. Patients with null/null variants were youngers, had higher untreated LDL-C and had the first ASCVD event earlier. Free-event survival is longer in patients with defective variant compared with those patients with at least one null variant (p=0.02). CONCLUSIONS: HoFH is a severe life threating disease with a high genetic and phenotypic variability. The improvement in lipid-lowering treatment and LDL-C levels have contributed to reduce ASCVD events.

RESUMO

It is nowadays accepted that, independently of methodological issues, women commit fewer suicides than men but make more frequent attempts. Yet, female suicidal risk varies greatly along the lifetime and is linked to the most significant moments in it. A wide analysis of the existing literature was performed to provide a narrative description on the evolution of female suicidal rates from childhood to old age, considering the milestones in their life history. A detailed analysis of gender differences in suicidal behavior is key to establish preventive measures and priorities. More specific studies are needed to adapt future interventions on female suicide.

RESUMO

Motion capture systems have recently experienced a strong evolution. New cheap depth sensors and open source frameworks, such as OpenNI, allow for perceiving human motion on-line without using invasive systems. However, these proposals do not evaluate the validity of the obtained poses. This paper addresses this issue using a model-based pose generator to complement the OpenNI human tracker. The proposed system enforces kinematics constraints, eliminates odd poses and filters sensor noise, while learning the real dimensions of the performer's body. The system is composed by a PrimeSense sensor, an OpenNI tracker and a kinematics-based filter and has been extensively tested. Experiments show that the proposed system improves pure OpenNI results at a very low computational cost.

RESUMO

Dyslipidemia is a frequent side effect associated with nilotinib treatment. Patients with chronic myeloid leukemia (CML) under treatment with nilotinib who develop dyslipidemia have been shown to have a higher risk of presenting atherosclerotic cardiovascular disease (ACVD). Therapeutic discontinuation in selected individuals could be a strategy in order to prevent the development of ACVD. Observational study of patients with CML under nilotinib treatment. The lipid values were gathered before starting with nilotinib and after 3 months. Such values were also measured before discontinuation in patients who suspended nilotinib treatment, as well as 3 and 12 months later. 32 patients were included, 19 of them treated in monotherapy with nilotinib. The concentrations of total cholesterol and low-density lipoproteins (LDL) increased significantly after 3 months of treatment (27.29 mg/dL ± 22.88, p < 0.01). Of the total number of patients treated, 12 discontinued the treatment. LDL concentration was significantly reduced after 3 months of the nilotinib discontinuation (- 27.58 mg/dL ± 38.30, p = 0.030), remaining substantially lower after 12 months, compared to the time previous to discontinuation (- 24.58 mg/dL ± 37.31, p = 0.043). Nilotinib suspension reduces significantly LDL concentrations. These data support the strategy of therapeutic discontinuation in order to prevent future cardiovascular complications, especially in patients with prior cardiovascular risk factors.

RESUMO

AIMS: Most heterozygous familial hypercholesterolaemia (FH) patients require intensive lipid-lowering therapy (LLT) including PCSK9 inhibitors (PCSK9is) to reach current low-density lipoprotein cholesterol (LDL-C) goals. Persistence with chronic treatment is important to reduce the burden of atherosclerotic cardiovascular disease. We analysed persistence, efficacy, and impact on quality of life (QoL) of PCSK9i in FH patients in clinical practice setting. METHODS AND RESULTS: Spanish Familial Hypercholesterolaemia Cohort Study (SAFEHEART) is an open, prospective study in genetically defined FH patients in Spain. Patients ≥18 years of age (n = 696, 46% females) on stable LLT treated with PCSK9i were analysed. Median LDL-C at starting PCSK9i was 145 mg/dL [interquartile range (IQR), 123-177], 3.8 mmol/L (IQR 3.2-4.6). After a median follow up of 3.7 years (IQR 2.3-4.8), 27 patients (4%) discontinued PCSK9i treatment: 5 temporarily (0.7%) and 22 permanently (3.2%). Persistence with PCSK9i was 96.1% in the whole period. Median LDL-C levels and % LDL-C reduction attained after 1 year of treatment and in the last follow-up visit were 63 mg/dL (IQR 43-88), 1.6 mmol/L (IQR 1.1-2.23); 61 mg/dL (IQR 44-82), 1.6 mmol/L (IQR 1.1-2.1); 57.6% (IQR 39.5-69); and 58% (IQR 44-68), respectively. 2016 and 2019 ESC/EAS LDL-C goals were attained by 77 and 48% of patients, respectively, at the last follow-up visit (P < 0.001). Mean QoL score increased slightly in the first year and remained stable. CONCLUSION: Long-term persistence with PCSK9i in FH patients is very high, with a good QoL. Effectiveness in LDL-C reduction and LDL-C goal achievement dramatically improved with PCSK9i in this high-risk population in clinical practice setting. TRIAL REGISTRATION: ClinicalTrials.gov number NCT02693548.

RESUMO

Migrant patients arriving in Spain often come from countries where there is no universal access to healthcare. Although the prevalence of arterial hypertension (HTN) is lower in West Africa than in Spain, there is a higher prevalence of masked HT due to the absence of health screening. Furthermore, patients with secondary hypertension may not be diagnosed. We present the case of a 36-year-old Senegalese man, with no known pathological history, resident for a year in Spain, who debuted with a hypertensive emergency. At the time of diagnosis, the patient had severe end-organ damage (hypertensive heart disease, hypertensive retinopathy). After the study, he was diagnosed with arterial hypertension secondary to malformation of the renal artery. After performing angioplasty, blood pressure normalized and, at 18 months, target organ damage had reduced. Migrants who arrive in our country must be incorporated into health screening systems to diagnose and treat possible unknown pathologies. In our case, the clue to secondary hypertension was the development of resistant hypertension with target organ damage in a young subject.

RESUMO

Introduction Suicide is the second leading cause of premature death in people between 15 and 29 years old and the third in young people between 15 and 19 years old. Adolescence is a critical period concerning mental health disorders since there is greater vulnerability to suicidal behaviors. The situation in Latin America is worrying, with Chile being one of the two countries where suicide rates of children and adolescents increase yearly. This study aims to analyze clinical, psychological, family, and social risk factors associated with suicidal behavior in a clinical sample of adolescents treated in the public health system of the Maule region. Methods The study design is cross- sectional. We used a sample of 388 adolescents between 10 and 21 years old admitted to the health system of the Maule Region. The participants were evaluated by applying five measuring instruments (The Barrat Impulsivity Scale, The Difficulties in Emotional Regulation Scale, The Depression, Anxiety and Stress Scale, The General Help-Seeking Questionnaire for mental health problems in adolescents, and The Columbia Suicide Severity Rating Scale) in addition to collecting social and family information and relevant clinical history from the medical records. Results The analysis allowed us to identify distinctive characteristics of adolescent suicidal behavior by describing clinical, psychological, and family social factors. Conclusions Adolescents with a history of suicide attempts are characterized by having suicidal ideation, anxious-depressive symptoms, stress, insomnia, and impulsiveness. Likewise, they report being non-religious, belonging to sexual minorities, and victims of sexual harassment and/or abuse.


Introducción El suicidio es la segunda causa de muerte prematura en personas entre 15 y 29 años, y la tercera en jóvenes entre 15 y 19 años. La adolescencia es un periodo crítico, dado que existe mayor vulnerabilidad para conductas suicidas. La situación en América Latina es crítica, siendo Chile uno de los dos países donde las tasas de suicidio de niños y adolescentes aumentan año tras año. En este estudio se analizan factores de riesgo clínicos, psicológicos y sociofamiliares asociados con la conducta suicida, en una muestra clínica de adolescentes atendidos en el sistema de salud público de la región del Maule. Método El diseño del presente estudio es transversal. En él se utilizó una muestra de 388 adolescentes de 10 a 21 años ingresados al sistema de salud de la Región del Maule. Durante la recogida de información se aplicaron cinco instrumentos de medición (escalas de impulsividad de Barrat, de dificultades de regulación emocional, de depresión, ansiedad y estrés, cuestionario general de búsqueda de ayuda para problemas de salud mental en adolescentes y escala de clasificación de gravedad del suicidio de Columbia). Además se recabó información sociofamiliar y antecedentes relevantes desde las fichas clínicas. Resultados El análisis realizado permitió identificar características distintivas de la conducta suicida adolescente, mediante la descripción de factores clínicos, psicológicos y sociofamiliares evaluados. Conclusión Los adolescentes con historial de intentos de suicidio se caracterizan por presentar ideación suicida, sintomatología ansiosa- depresiva, estrés, insomnio e impulsividad. Asimismo, reportan no tener creencias religiosas, pertenecer a minorías sexuales y haber sido víctima de acoso y/o abuso sexual.

RESUMO

INTRODUCTION: Adolescent suicide is a worldwide public health problem, being the second and the third leading cause of death in the 15-29 and the 15-19 age groups, respectively. Among adolescents, it is estimated that for every suicide, there are 100-200 suicide attempts. Although 79% of suicides in the world occur in low/middle-income countries, most of scientific evidence comes from high-income and low-risk countries. In recent years, adolescent suicide rates have steadily increased in Chile. Deaths caused by self-harm increased by 220% in the population aged 10-19 years between 2000 and 2015. The Maule Region is one of the regions of Chile with the highest levels of suicide among those aged 15 and 19 years old. The objective of this study is to evaluate the trajectories of ideation and suicidal attempts in adolescents with psychiatric disorders treated within the public health system of the Maule Region, Chile, based on different clinical, psychological and neuropsychological factors. METHOD: A prospective naturalistic study of a clinical sample of adolescents under psychiatric treatment in the Maule Region, Chile. Adolescents will be evaluated using a thorough protocol that includes suicide-related clinical variables. The study seeks to establish patterns of change in the trajectories of ideation and suicide attempts among adolescents. ETHICS AND DISSEMINATION: Ethical approval was granted by the Scientific Ethics Committee of the Universidad Católica del Maule in Chile. This protocol was registered in ClinicalTrials.gov.

RESUMO

Background: Individuals with psychiatric diagnoses who are unemployed or underemployed are likely to disproportionately experience financial hardship and, in turn, lower life satisfaction (LS). Understanding the mechanisms though which financial hardship affects LS is essential to inform effective economic empowerment interventions for this population. Aim: To examine if subjective financial hardship (SFH) mediates the relationship between objective financial hardship (OFH) and LS, and whether hope, and its agency and pathways components, further mediate the effect of SFH on LS among individuals with psychiatric diagnoses seeking employment. Methods: We conducted structured interviews with participants (N = 215) of two peer-run employment programs using indicators of OFH and SFH and standardized scales for hope (overall hope, hope agency, and hope pathways) and LS. Three structural equation models were employed to test measurement models for OFH and SFH, and mediational relationships. Covariates included gender, age, psychiatric diagnosis, race/ethnicity, education, income, employment status, SSI/SSDI receipt, and site. Results: Confirmatory factor analysis (CFA) for items measuring OFH and SFH supported two separate hypothesized factors. OFH had a strong and significant total effect on SFH [standardized beta (B) = 0.68] and LS (B = 0.49), and a weak-to-moderate effect on hope (B = -0.31). SFH alone mediated up to 94% of the effect of OFH on LS (indirect effect B = -0.46, p < 0.01). The effect of SFH on LS through hope was small (indirect effect B = -0.09, p < 0.05), primarily through hope agency (indirect effect B = -0.13, p < 0.01) and not hope pathways. Black and Hispanic ethno-racial identification seemed to buffer the effect of financial hardship on hope and LS. Individuals identifying as Black reported significantly higher overall hope (B = 0.41-0.47) and higher LS (B = 0.29-0.46), net of the effect of OFH and SFH. Conclusion: SFH is a strong mediator of the relationship between OFH and LS in our study of unemployed and underemployed individuals with psychiatric diagnoses. Hope, and particularly its agency component, further mediate a modest but significant proportion of the association between SFH and LS. Economic empowerment interventions for this population should address objective and subjective financial stressors, foster a sense of agency, and consider the diverse effects of financial hardship across ethno-racial groups.

RESUMO

Renal infarction is a rare disease whose incidence is less than 1%. The symptoms can be abdominal or flank pain, nausea, vomiting, fever or hypertension. The diagnosis is complex, and it is based on symptoms, blood analysis with an elevated level of lactate dehydrogenase and computed tomography angiography. The two major causes of renal infarction are thromboembolism and in situ thrombosis. The treatment depends on an adequate etiological diagnosis.

RESUMO

Treatment of chronic myeloid leukaemia (CML) is based on tyrosine kinase inhibitors (TKI), whose introduction in 2001 improved the survival rate after 5 years from 40 to 90%. The longevity increase has been accompanied by a higher incidence of cardiovascular events (CVE) that can be explained due to the sum of cardiovascular risk factors (CVRF) together with the secondary effects of the TKI. The effect of the TKI over the blood pressure control is still unknown. An observational cross-sectional study of patients with CML under treatment with TKI (imatinib, dasatinib and nilotinib) was conducted. Blood pressure was analyzed through sphygmomanometer and 24-h ambulatory blood pressure monitoring (ABPM). A total of 73 patients were included, 57 treated with a single line of treatment. 32.9% of the total of individuals under this study showed uncontrolled blood pressure according to the ABPM. The factors related to uncontrolled BP were overweight, dyslipidemia, alcohol use, pulse wave velocity a high/very high cardiovascular risk. The subjects who received treatment with nilotinib did present worse control of their blood pressure in ABPM than those treated with imatinib and dasatinib (p = 0.041). This finding could indicate that an uncontrolled blood pressure is implied in the pro-inflammatory and pro-atherogenic mechanism underlying the development of the cardiovascular disease in those patients under treatment with nilotinib. The ABPM is a useful tool in the diagnosis and treatment of HT, being the reason why it should be included in the assessment of patients with CML whose HT diagnosis proves uncertain.
