    Cardiovascular diseases represent a severe threat for humanity, being the first cause of death and hospitalization in both genders. An impressive number of studies have been developed in order to identify a set of factors causing this kind of illness, but only few of them were able to pay significant resources in analyzing large population samples (tens of thousands) and for longer periods of time (decades). This paper’s objective is to continue the previous researches of the eProCord project and to validate with concrete data the theoretical model developed for the attributable risk (AR). It will consider the same risk factors for myocardial infarction identified by INTERHEART study and the same work hypothesis. We will also evaluate if a certain value of the AR is also confirmed by the invoked disease of the patient. Using statistical and data mining tools we will investigate the prediction potential of the chosen factors and the opportunity to extend them in order to capture any cardiovascular disease. The empirical tests rely for now on a sample of 236 patients.Cardiovascular Disease, Myocardial Infarction, Attributable Risk, Roc, Data Mining, Classification

    From its appearance until nowadays, the internet saw a spectacular growth not only in terms of websites number and information volume, but also in terms of the number of visitors. Therefore, the need of an overall analysis regarding both the web sites and the content provided by them was required. Thus, a new branch of research was developed, namely web mining, that aims to discover useful information and knowledge, based not only on the analysis of websites and content, but also on the way in which the users interact with them. The aim of the present paper is to design a database that captures only the relevant data from logs in a way that will allow to store and manage large sets of temporal data with common tools in real time. In our work, we rely on different web sites or website sections with known architecture and we test several hypotheses from the literature in order to extend the framework to sites with unknown or chaotic structure, which are non-transparent in determining the type of visited pages. In doing this, we will start from non-proprietary, preexisting raw server logs.Knowledge Management, Web Mining, Data Preprocessing, Decision Trees, Databases

    Even if the foundation in the field of eHealth was set almost half century ago, the current achievements’ status does not place Romania on a good position in a European ranking. The efforts made during the last years are promising, but they still cannot surpass the enormous gaps in many eHealth indicators. This is not a surprising fact because the eHealth level must be sustained by a healthy and stable sanitary system and infrastructure, which, in our country, is almost in collapse, especially now in the context of global economic and financial crisis. We consider being guilty for these circumstances the lack of a clear and solid mid-term strategy developed at the level of the Ministry of Health (MoH), harmonized in a global legal and regulatory framework as well, and also the non-correlated researcher groups interests. The good attitude of practitioners regarding the challenges of new technologies and the political will can still give a chance to the Romanian healthcare system and to its modern faces

    Introduction Recent statistics show an increase in the prevalence of the elderly population. The year 2012 was declared European Year for Active Ageing and Solidarity between Generations, and the European Commission launched campaigns like The Active and Assisted Living Joint Program (AAL JP). Rehabilitation in the elderly is a desideratum, but the problems of rehabilitation in the elderly are numerous. The aim of the study was to evaluate degree of acceptance/implementation of different technologies in Romania, of monitoring in the rehabilitation activity conducted at home. Material and methods the study comprised 154 persons with a mean age of 73.37 ± 7.33 years, of which 64 (41.6%) male and 90 (58.4%) female. All subjects completed a questionnaire regarding the living conditions and health status, about the degree of acceptance of intelligent technologies for monitoring current health status/reporting acute events. Results 18.2% used the Internet frequently, and the rest used it almost never or rarely. 71.9 % of patients agreed to wear a portable sensor (p=0.07 between men and women), 33.1% accepted videocam, 47.4% accepted a screen, 41.3% accepted living room monitoring, 68% sensor in the room on the wall and 69.1% accepted fall detection sensor. No significant differences were found regarding the acceptance vs rejection of personal sensors, living room monitoring, sensors in the room, fall detection sensors depending on the gender, income level, type of caregiving. Using of videocam and screen was influenced by type of care giving and income (p=0.002, p<0.001, respectively for screen p=0.032 and p=0.003). In conclusion, Romanian old people are not keen on using intelligent devices for health status related to acute event monitoring. More programs and measures are needed for device implementation in real life

    Introduction. The increasing prevalence of peripheral arterial disease (PAD) among women is becoming a general healthcare issue, as this populational group is still underrepresented in clinical trials and registries addressing this disease. The aim of this research is to determine women peculiarities in both classical and novel atherosclerosis risk factors in patients admitted in a Romanian Rehabilitation Hospital. Material and methods. 83 consecutive female patients with a mean age of 68.48±10.39 years, symptomatic PAD and a pathological ankle-brachial index were included in the analysis. Data regarding the traditional and novel cardiovascular risk factors, both clinical, biological and paraclinical parameters were all registered. A subgroup of 40 subjects had novel inflammatory markers (hs-CRP, IL-6 and TNF-α) measured, which were compared in a case-control manner to those of 17 agematched healthy controls. Results. Traditional risk factors most prevalent in our overall cohort were hypertension (85%), smoking (44.57%) and diabetes mellitus (45.7%). Mean ankle-brachial index was 0.47±0.17. Novel inflammatory markers were significantly higher in women with symptomatic PAD compared to healthy controls: hs-CRP (p<0.0001), IL-6 (p=0.0053 and TNF-α (p=0.005). Multivariate statistical analysis found ankle-brachial index (ABI)- (p<0.0001), diastolic blood pressure (p=0.0272), obesity (p=0.0445), LDL-cholesterol (p=0.0018), HDL-cholesterol (p=0.0092) and serum creatinine (p<0.0001) to be independent predictors for a more advanced PAD. 59% of the patients exhibited critical limb ischemia on admission, while 60.24% had at least one major arterial occlusion on angiography. Percutaneous revascularization was the most employed treatment method, with 42% of subjects receiving PTA compared to 21.7% in the surgical arm. Conclusion. Women with PAD have specific clinical and biological characteristics that ultimately affect treatment modality, prescription of a rehabilitation program and outcome

    Background: Metabolic syndrome is associated with an increase in cardiovascular morbidity and mortality. Since the first description of MS, several definitions have been elaborated (IDF, AHA, Who, NCEP). Arterial stiffness is a strong independent predictor of cardiovascular events and cardiovascular mortality in various groups of patients. Aim: The purpose of present study was to investigate the impact of the different definitions of MS on arterial stiffness. Material and Methods: we investigated 214 patients, mean age 60.04±9.98 years. Arterial stiffness was evaluated using TensioMed TM Arteriograph. Results: Using the three definitions of the metabolic syndrome – IDF 2005, AHA, NCEP -, a proportion of 71.5% (153 patients), 72.9% (156 patients) and 62.1% (133 patients), respectively, had metabolic syndrome. Pulse wave velocity in the group of patients with metabolic syndrome was increased compared to those without metabolic syndrome, but the difference was not statistically significant (IDF - 10.37±2.13m/sec vs 10.04±2.21m/sec, AHA 10.40±2.14m/sec vs 9.93±2.19m/sec, NCEP 10.47±1.86m/sec vs 9.95±2.55m/sec). A statistically significant difference between pulse wave velocity in men with metabolic syndrome compared to those without metabolic syndrome was found, the relationship being not true in women. Conclusion: Patients with MS (especially men) have increased arterial stiffness parameters than those without metabolic syndrome. All the three definitions used have the same ability to identify patients with arterial stiffness. Arterial stiffness parameters are more altered as the number of criteria for the definition of metabolic syndrome increases, regardless of the definition used

    New Insights on the Relationship between Leptin, Ghrelin, and Leptin/Ghrelin Ratio Enforced by Body Mass Index in Obesity and Diabetes

    Currently, adipose tissue is considered an endocrine organ, however, there are still many questions regarding the roles of adipokines—leptin and ghrelin being two adipokines. The purpose of the study was to assess the relationship between the adipokines and their ratio with obesity and diabetes. Methods: Sixty patients (mean age 61.88 ± 10.08) were evaluated. Cardiovascular risk factors, leptin, ghrelin, and insulin resistance score values were assessed. The patients were classified according to their body mass index (BMI) as normal weight, overweight, and obese. Results: 20% normal weight, 51.7% overweight, 28.3% obese, and 23.3% diabetic. Obese patients had higher leptin values (in obese 34,360 pg/mL vs. overweight 18,000 pg/mL vs. normal weight 14,350 pg/mL, p = 0.0049) and leptin/ghrelin ratio (1055 ± 641 vs. 771.36 ± 921 vs. 370.7 ± 257, p = 0.0228). Stratifying the analyses according to the presence of obesity and patients’ gender, differences were found for leptin (p = 0.0020 in women, p = 0.0055 in men) and leptin/ghrelin ratio (p = 0.048 in women, p = 0.004 in men). Mean leptin/BMI and leptin/ghrelin/BMI ratios were significantly higher, and the ghrelin/BMI ratio was significantly lower in obese and diabetic patients. In conclusion, obesity and diabetes are associated with changes not only in the total amount but also in the level of adipokines/kg/m2. Changes appear even in overweight subjects, offering a basis for early intervention in diabetic and obese patients

    Cardiac Toxicity Associated with Immune Checkpoint Inhibitors: A Systematic Review

    No full text
    Immune checkpoint inhibitors (ICIs) are an important advancement in the field of cancer treatment, significantly improving the survival of patients with a series of advanced malignancies, like melanoma, non-small cell lung cancer (NSCLC), hepatocellular carcinoma (HCC), renal cell carcinoma (RCC), and Hodgkin lymphoma. ICIs act upon T lymphocytes and antigen-presenting cells, targeting programmed cell death protein 1 (PD1), programmed cell death protein ligand 1 (PD-L1), and cytotoxic T-lymphocyte antigen 4 (CTLA-4), breaking the immune tolerance of the T cells against malignant cells and enhancing the body’s own immune response. A variety of cardiac-adverse effects are associated with ICI-based treatment, including pericarditis, arrhythmias, cardiomyopathy, and acute coronary syndrome, with myocarditis being the most studied due to its often-unexpected onset and severity. Overall, Myocarditis is rare but presents an immune-related adverse event (irAE) that has a high fatality rate. Considering the rising number of oncological patients treated with ICIs and the severity of their potential adverse effects, a good understanding and continuous investigation of cardiac irAEs is of the utmost importance. This systematic review aimed to revise recent publications (between 2016–2022) on ICI-induced cardiac toxicities and highlight the therapeutical approach and evolution in the selected cases
