RESUMO

The outbreak of the COVID-19 pandemic has had a wide range of negative consequences for higher education students. We explored the generalizability of the control-value theory of achievement emotions for e-learning, focusing on their antecedents. We involved 17019 higher education students from 13 countries, who completed an online survey during the first wave of the pandemic. A structural equation model revealed that proximal antecedents (e-learning self-efficacy, computer self-efficacy) mediated the relation between environmental antecedents (cognitive and motivational quality of the task) and positive and negative achievement emotions, with some exceptions. The model was invariant across country, area of study, and gender. The rates of achievement emotions varied according to these same factors. Beyond their theoretical relevance, these findings could be the basis for policy recommendations to support stakeholders in coping with the challenges of e-learning and the current and future sequelae of the pandemic.

RESUMO

Health social work is a field with challenges, opportunities, and ways of professing social work that may vary between different national contexts. In this article, we look at how Romanian health social workers construct their professional identity through their everyday identity work. Drawing on a qualitative study based on interviews with 21 health social workers working in various organizational contexts, we analyze what health social workers say they do and how this shapes their self-conception as professionals. Four main themes emerged from participants' descriptions: being a helping professional, being a mediator, gaining recognition, and contending with limits. Through these themes, participants articulated the everyday struggles and satisfactions specific to working as recently recognized professionals in Romanian health and welfare systems not always supportive of their work.

RESUMO

This study examined regret following HIV serostatus disclosure and associated factors in under-investigated contexts (Mali, Morocco, Democratic Republic of the Congo, Ecuador and Romania). A community-based cross-sectional study was implemented by a mixed consortium [researchers/community-based organizations (CBO)]. Trained CBO members interviewed 1,500 PLHIV in contact with CBOs using a 125-item questionnaire. A weighted multivariate logistic regression was performed. Among the 1,212 participants included in the analysis, 290 (23.9 %) declared that disclosure was a mistake. Female gender, percentage of PLHIV's network knowing about one's seropositivity from a third party, having suffered rejection after disclosure, having suffered HIV-based discrimination at work, perceived seriousness of infection score, daily loneliness, property index and self-esteem score were independently associated with regret. Discrimination, as well as individual characteristics and skills may affect the disclosure experience. Interventions aiming at improving PLHIV skills and reducing their social isolation may facilitate the disclosure process and avoid negative consequences.

RESUMO

The present study aimed to identify social and individual factors associated with satisfaction with sexual life (SSL) in people living with HIV (PLHIV) in contact with a community-based organisation in Romania. A standardised questionnaire was administered (N = 300) in a community-based research study. Multivariate analysis (using a weighted logistic regression restricted to the 291 respondents who answered a question about SSL) was used to determine factors associated with SSL. Sixty-eight per cent of the participants declared that they were satisfied with their sexual life. The following individual factors were associated with SSL: being over 36 years old (Odds Ratio [95% CI]: 0.27 [0.13-0.55]), having ceased sexual intercourse because of HIV (0.33 [0.14-0.76]), not knowing how infection had occurred (0.29 [0.15-0.59]), being officially registered with a level of disability lower than "severe" (0.47 [0.23-0.98]) and having a higher self-efficacy score (1.36 [1.14-1.61]). Living in a couple (7.60 [3.69-15.66]), knowing at least one HIV-infected person who had publicly disclosed his/her seropositivity (2.23 [1.03-4.84]), and having a higher social exclusion score (0.91 [0.82-1]) were social factors associated with SSL. The results suggest that HIV service providers must be sensitised to the necessity of systematically including the topic of PLHIV SSL in field interventions. Self-empowerment, positive examples of public disclosure, promoting the benefits of living in a couple, and supporting social integration can all improve the well-being of PLHIV, including their SSL.

RESUMO

BACKGROUND: Coronary bifurcation lesions are associated with less favourable outcome as compared to other lesion subsets. The role of drug-coated balloons (DCB) for bifurcation lesions has been only investigated in small studies so far, which reported encouraging results. We here describe the results of EASTBOURNE-BIF prospective registry, in which a sirolimus-DCB was used for the treatment of bifurcation lesions. METHODS: Overall, 194 patients with bifurcations lesions identified in the EASTBOURNE study (Medina 1.1.1/1.1.0/1.0.1/0.1.1/0.1.0) were compared with 1049 patients with de-novo lesions from the same registry. Both a blended-strategy using a drug-eluting stent in the main branch and a DCB in the side branch as well as a full-DCB approach were used in the treatment of bifurcation lesions. RESULTS: At one year of follow-up the study primary endpoint, target-lesion revascularization occurred at a similar rate in the bifurcation group versus the de-novo group (4.2 vs. 2%, P=0.28). Similar outcomes were observed in terms of all-cause death (3.3 vs. 1.4%, P=0.138), major adverse cardiovascular events (8.8 vs. 5.2%, P=0.081) and the rate of spontaneous myocardial infarction (2.8 vs. 1.0%, P=0.117). CONCLUSIONS: The results of EASTBOURNE-BIF study show how the use of this DCB alone or in combination with drug eluting stents could represent a safe and effective alternative to stents for the treatment of bifurcations.

RESUMO

Continuous advances in the field of interventional cardiology have led to the development of drug-coated balloons (DCB). These represent a promising device for overcoming the well-known limitations of traditional metallic stents, which are associated with a persistent yearly increased risk of adverse events. This technology has the ability to homogeneously transfer the drug into the vessel wall in the absence of a permanent prosthesis implanted in the coronary vessel. Robust data support the use of DCB for the treatment of in-stent restenosis, but there is also currently growing evidence from long-term follow-up of large randomised clinical trials regarding the use of these devices in other scenarios, such as de novo small and large vessel disease, complex bifurcations, and diffuse coronary disease. Other critical clinical settings such as diabetes mellitus, high bleeding risk patients and acute coronary syndromes could be approached in the upcoming future by using DCB, alone or as part of a blended strategy in combination with drug-eluting stents. There have been important scientific and technical advances in the DCB field in recent years. The purpose of this paper is to review the most current data regarding the use of DCB, including the mid- and long-term follow-up reports on the safety and efficacy of this novel strategy in different clinical and angiographic scenarios.

RESUMO

Acute myocardial infarction is one of the most serious cardiovascular pathologies, impacting patients' long-term outcomes and health systems worldwide. Significant effort is directed toward the development of biosensing technologies, which are able to efficiently and accurately detect an early rise of cardiac troponin levels, the gold standard in detecting myocardial injury. In this context, this work aims to develop a microfluidic plasmonic chip for the fast and accurate real-time detection of the cardiac troponin I biomarker (cTnI) via three complementary detection techniques using portable equipment. Furthermore, the study focuses on providing a better understanding of the thermoplasmonic biosensing mechanism taking advantage of the intrinsic photothermal properties of gold nanoparticles. Specifically, a plasmonic nanoplatform based on immobilized gold nanobipyramids was fabricated, exhibiting optical and thermoplasmonic properties that promote, based on a sandwich-like immunoassay, the "proof-of-concept" multimodal detection of cTnI via localized surface plasmon resonance, surface enhanced Raman spectroscopy and thermoplasmonic effects under simulated conditions. Furthermore, after the integration of the plasmonic nanoplatform in a microfluidic channel, the determination of cTnI in 16 real plasma samples was successfully realized via thermoplasmonic detection. The results are compared with a conventional high-sensitivity enzyme-linked immunosorbent clinical assay (ELISA), showing high sensitivity (75%) and specificity (100%) as well as fast response features (5 minutes). Thus, the proposed portable and miniaturized microfluidic plasmonic chip is successfully validated for clinical applications and transferred to clinical settings for the early diagnosis of cardiac diseases, leading towards the progress of personalized medicine.

RESUMO

(1) Background: The success of carotid revascularization depends on the accurate grading of carotid stenoses. Therefore, it is important for every vascular center to establish its protocols for the same. In this study, we aimed to determine the peak systolic velocity (PSV) thresholds that can predict moderate and severe internal carotid artery (ICA) stenoses. (2) Methods: To achieve this, we enrolled patients who underwent both duplex ultrasound (DUS) and invasive carotid artery digital subtraction angiography (DSA). The degree of ICA stenosis was assessed using the North American Symptomatic Carotid Endarterectomy Trial (NASCET) and the European Carotid Surgery Trial (ECST) protocols. The PSV thresholds were determined using receiver operating characteristic (ROC) curves. (3) Results: Our study included 47 stenoses, and we found that the PSV cut-off for predicting ≥70% NASCET ICA stenoses was 200 cm/s (sensitivity 90.32%, specificity 93.75%). However, PSV did not correlate significantly with ≥50% NASCET ICA stenoses. On the other hand, the optimal PSV threshold for predicting ≥80% ECST ICA stenoses was 180 cm/s (sensitivity 100%, specificity 81.82%). (4) Conclusions: Based on our findings, we concluded that PSV is a good and simple marker for the identification of severe stenoses. We found that PSV values correlate significantly with severe NASCET and ECST stenoses, with 200 cm/s and 180 cm/s PSV thresholds. However, PSV was not reliable with moderate NASCET stenoses. In such cases, complementary imaging should be used.

RESUMO

Atherosclerosis in a progressive disease that is systemic in nature, and hence the simultaneous presentation of coronary artery disease (CAD) and peripheral artery disease (PAD) is not uncommon. As clinically manifested PAD is associated with worse cardiovascular outcomes, the timely identification of subclinical atherosclerosis seems of utmost importance. Ultrasonography (US) is an ideal imaging modality for assessing PAD that is easy to use, accurate, widely available and avoids unnecessary exposure to radiation. Several US parameters have been proposed in the assessment of PAD, with varying prognostic usefulness, depending on disease location. The aim of this review is to summarize the most important evidence available on the association between US-detected atherosclerosis in different vascular sites and the presence and severity of CAD, as well as the impact of the early detection of PAD on the outcomes of patients presenting with CAD.

RESUMO

Trauma scientists have raised the alarm about the devastating consequences of the Ukraine war on mental health. We examined how higher education students-as indirect victims-coped with this conflict and how they emotionally reacted during 2022. We involved 2314 students from 16 countries through an online survey. A structural equation model indicated significant relations between war-related worry about military and macroeconomics domains and two coping strategies (opposition, support giving), in turn significantly linked with six emotions. The model was strongly invariant across gender, study field, and geographic area. The most frequent emotions were anger and anxiety, followed by two future-centred emotions (hopelessness and hope). Emotions were more frequent for females and students of the countries geographically close to the war region. Our findings call for evidence-based policy recommendations to be implemented by institutions to combat the negative short and long-term psychological sequelae of being witnesses of armed conflicts.

RESUMO

Percutaneous coronary intervention (PCI) with drug-eluting stents (DES) represents the treatment of choice for the majority of patients with coronary artery disease. While currently available DES, in addition to physiological support, has failed to show the non-inferiority to coronary artery bypass grafting (CABG) in terms of cumulative incidence of clinical events over the short-term follow-up. Studies have also shown that DES is associated with an increased risk of target vessel revascularization compared to CABG after long-term follow-up. Drug-coated balloons (DCB) have been shown to provide clinically significant benefits in the management of in-stent restenosis and diffuse coronary artery disease, as well as small coronary artery lesions. The aim of this review was to describe the inherent technical limitations of DES and highlight the potential advantages of PCI with DCB for long-term outcomes and potentially demonstrate its non-inferiority to CABG. Currently, ongoing studies will provide more information and help to understand if a blended therapy of DCB+DES can match the performance of CABG in the need for revascularization in more complex patients.

RESUMO

This study investigates the clinical relevance and therapeutic implications of the OCT identification of intracoronary superficial calcified plates (SCPs) in acute coronary syndromes (ACSs). In 70 consecutive ACS patients (pts), we studied the three main underlying ACS mechanisms: plaque erosion (PE), plaque rupture and eruptive calcified nodule (CN). The PE lesions, occurring on an intact fibrous cap overlying a heterogeneous substrate, were identified in 12/70 pts (17.1%). PE on superficial calcified plates (PE-SCP) represented 58.3% of the PE lesions (7/12 pts) and had a 10% overall incidence in the culprit lesions (7/70 pts). PE-SCP lesions occurred mostly on the left anterior descending artery, correlated with white thrombi (85.7%) and had a proximal intraplaque site (71.4%). PE-SCP lesions were treated conservatively, as nonsignificant lesions, in 4/7 pts. Our study emphasizes that the coronary calcium-related ACS risk is not only associated with the spotty calcifications or CN but also with the PE-SCP lesions.

RESUMO

Anthracycline treatments are known to cause cardiotoxic long-term side effects in cancer survivors. Recently, a decrease in heart rate variability (HRV) has been identified in these patients, signaling autonomic dysfunction and altered cardiac fitness. This study aimed at evaluating changes in HRV in children treated with anthracyclines. A total of 35 pediatric patients with acute lymphoblastic leukemia were evaluated by means of a 24 h Holter ECG, at baseline and after reaching half the total cumulative dose of doxorubicin equivalent (120 mg/m2). Parameters of HRV were assessed, as well as any arrhythmic episodes, bradycardia and tachycardia percentages. The results showed a significant decrease in both time-domain and frequency-domain HRV parameters, following anthracycline treatment. The low-frequency (LF) to high-frequency (HF) parameters' ratio also displayed a significant difference (p = 0.035), suggestive of early cardiac autonomic dysfunction. Of note, none of the patients presented symptoms of heart disease or elevated troponins, and only two patients presented echocardiographic signs of diastolic dysfunction. The present study showed that cardiac autonomic nervous system regulation is compromised in children treated with anthracyclines even before reaching the total cumulative dose. Therefore, HRV parameters could be the first indicators of subclinical cardiac toxicity, making Holter ECG monitoring of the oncological patient a necessity.

RESUMO

BACKGROUND: Coronary lesions predilatation with semicompliant (SC) or non-compliant balloons (NC) may be insufficient to obtain an optimal stent expansion, which can lead to in-stent restenosis or thrombosis. Moreover, increasing evidence supporting an optimal lesion preparation is mandatory when drug coated balloons (DCB) are used. To this extent, more "aggressive tools" such as cutting/scoring balloons, atherectomy or lithotripsy may play an important role and improve outcomes. METHODS: We enrolled 78 consecutive patients from March 2020 to October 2020 with calcific/fibrotic or ostially-located lesions, which were prepared using scoring balloons, in addition to SC/NC balloons and other plaque modification strategies. The final treatment consisted in either stent or DCB usage. The primary endpoint was the rate of clinically-driven target lesion revascularization. Secondary endpoints entailed the procedural success and the individual rates of major adverse cardiac events (MACE) at 12 months. RESULTS: Most of the patients had left main (LM) or ostial lesions, 65% of them being moderate/severely calcified, with further debulking strategies being required in 15 (19.2%) patients (rotational atherectomy, 3.8% or coronary intravascular lithotripsy, 15.3%). A high-rate of DCB usage was reported. Angiographic and procedural success was obtained in 77 and 76 patients, respectively. We encountered one vessel perforation, which was sealed with a covered stent, without consequence. During follo- up, we observed only 6 MACE, 6 target lesion revascularizations (TLR) and 2 cardiovascular deaths. CONCLUSIONS: Among patients with high complexity and calcific lesions, an optimal lesion preparation using a dedicated scoring balloon was associated with low clinical events at mid-term follow-up and may be considered to improve immediate procedural success rate.

RESUMO

During adolescence individuals face multiple stressful events, but it is not clear how these impact adolescents' adjustment and what factors buffer their negative effects. The present exploratory study investigates the relationship between frequency, proximity, and intensity of negative life events and occurrence of internalizing symptoms in a sample of Romanian adolescents. 2690 youth aged 15-16 from capital city of Romania filled in a series of measures from Youth in Europe Study. Hierarchical regression was employed to test for the explanatory value of individual (gender and family status), relational (parents and peer support), and negative life events on depressive and anxiety symptoms. Frequency and proximity of negative life events explained 35.8% in the displaying of depressive symptoms. After controlling for individual and relational variables, occurrence, proximity, and intensity of negative life events significantly contributed to explaining heightened anxiety symptoms (R2 = .246). Adolescents reporting more frequent, earlier in time and more intensive negative events also reported more depressive and anxiety symptoms, thus, supporting the relationship between occurrence of adversities and negative mental health outcomes.

RESUMO

Adolescence is a complicated, full of challenges and explorations period in life on the way to adulthood. The behaviour of adolescents is considerably re-configuring under the pressure of biological, psychological, and social transformations, and the internalization of community rules and values, as well as the adoption of desirable behaviours, is not always easy or successful. During adolescence, anomie can easily become an attractive status quo, but it can also evolve, however, relatively easy, to delinquency. This exploratory study, part of the Planet Youth project, is based on an analysis of 17 items from a questionnaire applied to a sample of 2,694 young people in Bucharest, Romania, in 2018, high schoolers in grades 9-11. The main objective of this approach was to assess the impact of some socio-cultural factors regarding school, family, peer group, and neighbourhood on the adoption of deviant and delinquent behaviours among Bucharest teenagers. For data analysis, two dependent variables were built by aggregating items in the questionnaire: the level of anomie (composed of 8 items) and deviant behaviour (composed of 17 items). As independent variables, 17 predictors composed from 67 questions from the questionnaire were used. The main results reflect a high level of anomie among the adolescents of Bucharest and a low level of deviance, and a weak link between these two variables. On the other hand, adolescent anomie and deviance are favoured by anger management, perceived peer attitudes to substance use and digital leisure, together with low parental surveillance.

RESUMO

Left main (LM) coronary artery disease is a high-risk lesion subset, with important prognostic implications for the patients. Recent advances in the field of interventional cardiology have narrowed the gap between surgical and percutaneous approach of this complex lesion setting. However, the rate of repeat revascularization remains higher in the case of percutaneous coronary intervention (PCI) on long-term follow-up. As such, the need for better stent optimization strategies has led to the development of intravascular imaging techniques, represented mainly by intravascular ultrasound (IVUS) and optical coherence tomography (OCT). These techniques are both able to provide excellent pre- and post-PCI guidance. While IVUS is an established modality in optimizing LM PCI, and is recommended by international revascularization guidelines, data and experience on the use of OCT are still limited. This review paper deeply analyzes the current role of OCT imaging in the setting of LM disease, particularly focusing on its utility in assessing plaque morphology and distribution, vessel dimensions and proper stent sizing, analyzing mechanisms of stent failure such as malapposition and underexpansion, guiding bifurcation stenting, as well as offering a direct comparison with IVUS in this critical clinical scenario, based on the most recent available data.

RESUMO

The use of high-sensitivity cardiac troponin (hs-cTn) assays has become part of the daily practice in most of the laboratories worldwide in the initial evaluation of the typical chest pain. Due to their early surge, the use of hs-cTn may reduce the time needed to recognise myocardial infarctions (MI), which is vital for the patients presenting in the emergency departments for chest pain. The latest European Society of Cardiology Guidelines did not only recognise their central role in the diagnosis algorithm but also recommended their use for rapid rule-in/rule-out of MI. High-sensitivity cardiac troponins are also powerful prognostic markers for long-term events and mortality, not only in a wide spectrum of other cardiovascular diseases (CVD) but also in several non-CVD pathologies. Moreover, these biomarkers became a powerful tool in special populations, such as paediatric patients and, most recently, COVID-19 patients. Although highly investigated, the assessment and interpretation of the hs-cTn changes are still challenging in the patients with basal elevation such as CKD or critically ill patients. Moreover, there are still various analytical characteristics not completely understood, such as circadian or sex variability, with major clinical implications. In this context, the present review focuses on summarizing the most recent research in the current use of hs-cTn, with a main consideration for its role in the diagnosis of MI but also its prognostic value. We have also carefully selected the most important studies regarding the challenges faced by clinicians from different specialties in the correct interpretation of this biomarker. Moreover, future perspectives have been proposed and analysed, as more research and cross-disciplinary collaboration are necessary to improve their performance.

RESUMO

Optical coherence tomography (OCT) is an ideal imaging technique for assessing culprit coronary plaque anatomy. We investigated the morphological features and mechanisms leading to plaque complication in a single-center observational retrospective study on 70 consecutive patients with an established diagnosis of acute coronary syndrome (ACS) who underwent OCT imaging after coronary angiography. Three prominent morphological entities were identified. Type I or intimal discontinuity, which was found to be the most common mechanism leading to ACS and was seen in 35 patients (50%), was associated with thrombus (68.6%; p = 0.001), mostly affected the proximal plaque segment (60%; p = 0.009), and had no distinctive underlying plaque features. Type II, a significant stenosis with vulnerability features (inflammation in 16 patients, 84.2%; thin-cap fibroatheroma (TCFA) in 10 patients, 52.6%) and a strong association with lipid-rich plaques (94.7%; p = 0.002), was observed in 19 patients (27.1%). Type III, a protrusive calcified nodule, which was found to be the dominant morphological pattern in 16 patients (22.9%), was found in longer plaques (20.8 mm vs. 16.8 mm ID vs. 12.4 mm SS; p = 0.04) and correlated well with TCFA (93.8%; p = 0.02) and inflammation (81.3%). These results emphasize the existence of a wide spectrum of coronary morphological patterns related to ACS.

RESUMO

Nutcracker and Wilkie syndromes are rare mesoaortic compression entities, and their association is even less common. Data on interventional treatment of these pathologies are still scarce, but results from limited case series are encouraging. We report the case of a previously healthy 45-year-old woman diagnosed with nutcracker and Wilkie syndromes who presented with macroscopic hematuria, intermittent pain in the left flank and hypogastric region, postprandial nausea, and unexplained significant weight loss. A successful endovascular approach with stent implantation in the left renal vein was performed, but the stent migrated toward the left kidney, and this acute complication was managed through an interventional strategy as well. At the three-month follow-up, the patient described a marked improvement in all symptoms, except for the macroscopic hematuria. As it was our strong belief that the approach was efficient, we further investigated the "hematuria", which eventually led to the diagnosis of endometrial carcinoma. A hysterectomy and bilateral adnexectomy were planned, and chemoradiotherapy was initiated with the goal of preoperative tumor reduction. To our knowledge, this is the first reported case in which both Wilkie and nutcracker syndromes were effectively treated by stent implantation in the left renal vein, complicated with very early stent migration due to inadequate apposition to the less compliant venous lumen. The treatment of the duodenal compression was indirectly included in the stenting of the left renal vein, as reclaiming the venous lumen widened the aortomesenteric angle. The aim of this review is to discuss our center's transcatheter experience with these rare disorders and explore the literature in order to establish the benefits and limitations of such an approach.
