RESUMEN

Enhancing an echocardiographic tool, aimed to detect even subtle left ventricular (LV) systolic function abnormalities, capable of obtaining both early diagnosis and risk prediction of heart disease, represents an ambitious, attractive, and arduous purpose in the modern era of cardiovascular imaging. Ideally, that tool should be simple, reliable, and reproducible, in order to be concretely applied in routine clinical practice. Importantly, that technique should be physiologically plausible and useful both at the population-level, as well as in the individual subject. For a long time, LV ejection fraction (EF) has been considered the first-line parameter for assessing LV global systolic function, strictly related to the prognosis, at least in some settings. However, LV EF limitations are well-known, even though frequently overemphasized, including its load-dependency. Therefore, myocardial strain techniques have been proposed, deemed able to disclose even subtle early LV function anomalies. Nevertheless, many disadvantages of myocardial strain have been reported as well. More recently, myocardial work (MW) analysis has been introduced as a new echocardiographic tool for the evaluation of LV global systolic function, attempting to overcome EF and strain disadvantages. However, MW has shown many limits as well. Notwithstanding, LV EF still remains a landmark functional classification marker for heart failure and cardiac oncology, allowing reliable fast reassessment of LV function changes during patient management, in order to guide treatment in individual cases as well. Notably, global longitudinal strain and MW parameters seem to show better meaningful results at the population-level, but controversial clinical impact, major limitations, wide cut-offs spread and overlap, when the single value needs to be applied to the single case. Taking into account the recent literature-based evidence, the scope of the present narrative critical review is trying to delineate the different types of information given by the described LV global systolic function parameters, both at the population-level and in the individual case, in order to trace a comparative analysis of advantages and limitations in clinical practice.

RESUMEN

Background: As hybrid radiotherapy technique can effectively balance dose distribution between targets and organs, it is necessary to evaluate the late effects related to radiotherapy. The aim of the study was to calculate and provide individual estimates of the risks for hybrid radiotherapy techniques in breast cancer patients. Methods: Whole-breast irradiation was performed in 43 breast cancer patients by using 3D conformal, intensity-modulated and hybrid techniques. The excess absolute risk (EAR), lifetime attributable risk (LAR) and normal tissue complication probability (NTCP) were calculated to estimate risks in organs. The risk variability in contralateral breast was assessed by using the patient's anatomic parameters. Results: Compared with IMRT and FinF, hybrid techniques achieved satisfactory dose distribution and comparable or lower estimated risks in organs. The LAR was estimated to be up to 0.549% for contralateral lung with advantages of tangential techniques over H-VMAT. For ipsilateral lung, the LAR was estimated to be up to 9.021%, but lower in H-VMAT and FinF without significant difference. The risk of thyroid was negligible in overall estimation. For contralateral breast, the LAR was estimated to be up to 0.865% with advantages of MH-IMRT and H-VMAT over TF-IMRT. The fraction of individual variability could be explained by using anatomic parameters of minimum breast distance (MBD) and minimum target concave angle (θMTCA). NTCP for all analyzed endpoints was significantly higher in TF-IMRT relative to FinF and hybrid techniques, while TH-IMRT and H-VMAT were presenting lower toxicity risk. However, MH-IMRT presented a higher probability of toxicity in lung. For most cases, H-VMAT demonstrated a benefit for contralateral breast, heart and lung sparing. Conclusion: The optimal treatment should be performed individually according to anatomic parameters and balances between EAR and NTCP. Individual assessment may assist in achieving optimal balances between targets and organs as well as supporting clinical decision-making processes.

RESUMEN

To classify contaminated sites into different risk classes, many different methods exist in Europe and worldwide. However, no systematic comparison of European risk classification methods has been carried out so far to carve out the advantages and disadvantages of the methods and to homogenize them. To address this research gap, this study aims at comparing the Swedish Method for Inventories of Contaminated Sites (MIFO) with the German Individual Assessment of Contaminated Sites Method (EB) from the Hessian Agency for Nature Conservation, Environment and Geology (HLNUG) regarding the risk class categorization of 51 contaminated sites. The results revealed that with the MIFO 39% fewer contaminated sites are assigned to risk classes 1 and 2 and thus, subject to remediation compared to the EB. Moreover, in comparison to the EB, the MIFO showed a lower comparability, traceability, and a larger room for interpretation, which could be related to the lack of a quantitative approach such as a point or ranking system in the MIFO. Hence, we recommend providing the MIFO and other methods that lack a quantitative approach with a point and/or ranking system, similar to the EB, to increase their objectivity for the risk class categorization of contaminated sites.

RESUMEN

OBJECTIVE: To explore the accuracy of estimated 24-h urinary iodine excretion (24-h UIEest) in assessing iodine nutritional status. DESIGN: Fasting venous blood, 24-h and spot urine samples were collected during the day. The urinary iodine concentration (UIC) and urinary creatinine concentration (UCrC) were measured, and the urinary iodine-to-creatinine ratio (UI/Cr), 24-h UIEest, and 24-h urinary iodine excretion (24-h UIE) were calculated. At the population level, correlation and consistency between UIC, UI/Cr, 24-h UIEest and 24-h UIE were assessed using correlation analysis and Bland-Altman plots. At the individual level, receiver operating characteristic (ROC) curves were used to analyse the accuracy of the above indicators for evaluating insufficient and excessive iodine intake. The reference interval of 24-h UIEest was established based on percentile values. SETTING: Indicator can accurately evaluate individual iodine nutrition during pregnancy remains controversial. PARTICIPANTS: Pregnant women (n 788). RESULTS: Using 24-h UIE as standard, the correlation coefficients of 24-h UIEest from different periods of the day ranged from 0·409 to 0·531, and the relative average differences ranged from 4·4 % to 10·9 %. For diagnosis of insufficient iodine intake, the area under the ROC curve of 24-h UIEest was 0·754, sensitivity and specificity were 79·6 % and 65·4 %, respectively. For diagnosis of excessive iodine intake, the area of 24-h UIEest was 0·771, sensitivity and specificity were 66·7 % and 82·0 %, respectively. The reference interval of 24-h UIEest was 58·43-597·65 µg. CONCLUSIONS: Twenty-four-hour UIEest can better indicate iodine nutritional status at a relatively large sample size in a given population of pregnant women. It can be used for early screening at the individual level to obtain more lead time for pregnant women.

RESUMEN

BACKGROUND AND PURPOSE: Team-based learning (TBL) has been successfully applied to multiple healthcare education disciplines. A primary tenet of TBL is the development of solutions leveraging the collective knowledge of a team rather than the individual competency of any one student. In an effort to enhance individual student accountability, an individual verbal defense (IVD) format was implemented in a multi-campus TBL-based pharmacotherapeutics course. The study sought to investigate the use of TBL-IVD embedded within a traditional TBL format on student engagement, teaching style preferences, and exam performance compared to a TBL-only format. EDUCATIONAL ACTIVITY AND SETTING: In this cross-sectional study, second-year pharmacy students enrolled in a pharmacotherapeutics course during fall 2019 completed an 11-item survey. The survey was designed to assess TBL-IVD on student engagement and teaching style preference. Free-response qualitative feedback was solicited to assess positive-negative themes related to the activity. Aggregate exam performance for community-acquired pneumonia (CAP) related content was compared to historical exam data to assess the impact on student performance. FINDINGS: The majority of students (72%, n = 54) preferred the TBL-IVD compared to a TBL-only format. Students reported higher engagement with TBL-IVD (84%, n = 63). Correct exam responses for CAP related content were higher in the TBL-IVD group (67% vs. 55%, P < .001). Positive themes included an increased opportunity to defend recommendations verbally and increased interaction with an on-campus faculty member. SUMMARY: The study demonstrates the addition of IVD can enhance student perceptions, confidence, and performance within a large, multi-campus, TBL-based pharmacotherapeutics course.

RESUMEN

This article focuses on the importance of the right to effective participation of children in conflict with the law in criminal (youth justice) proceedings. In particular, it explores two procedural aspects which are closely related to the right to child-friendly legal aid and the role of individual assessment. The authors claim that qualitatively identifying the needs of the child (through the instrument of individual assessment) and establishing a relationship of trust with a specifically trained legal aid lawyer is critical in raising the child's status to that of an active participant in the proceedings and ensuring that the best interests of the child are observed. The authors also suggest that such an initial encounter within the justice system forms an attitude (of either confidence or rejection) of the child towards public institutions and, accordingly, directly affects the effectiveness of further interventions. To support their position, the authors of the paper bring several examples from the comparative research carried out in two European projects, noting, regretfully, that the initial interventions often suffer from formal implementation and lack a systemic approach.

RESUMEN

Reliable paradigms and imaging measures of individual-level brain activity are paramount when reaching from group-level research studies to clinical assessment of individual patients. Magnetoencephalography (MEG) provides a direct, non-invasive measure of cortical processing with high spatiotemporal accuracy, and is thus well suited for assessment of functional brain damage in patients with language difficulties. This MEG study aimed to identify, in a delayed picture naming paradigm, source-localized evoked activity and modulations of cortical oscillations that show high test-retest reliability across measurement days in healthy individuals, demonstrating their applicability in clinical settings. For patients with a language disorder picture naming can be a challenging task. Therefore, we also determined whether a semantic judgment task ('Is this item living?') with a spoken response ("yes"/"no") would suffice to induce comparably consistent activity within brain regions related to language production. The MEG data was collected from 19 healthy participants on two separate days. In picture naming, evoked activity was consistent across measurement days (intraclass correlation coefficient (ICC)>0.4) in the left frontal (400-800 ms after image onset), sensorimotor (200-800 ms), parietal (200-600 ms), temporal (200-800 ms), occipital (400-800 ms) and cingulate (600-800 ms) regions, as well as the right temporal (600-800 ms) region. In the semantic judgment task, consistent evoked activity was spatially more limited, occurring in the left temporal (200-800 ms), sensorimotor (400-800 ms), occipital (400-600 ms) and subparietal (600-800 ms) regions, and the right supramarginal cortex (600-800 ms). The delayed naming task showed typical beta oscillatory suppression in premotor and sensorimotor regions (800-1200 ms) but other consistent modulations of oscillatory activity were mostly observed in posterior cortical regions that have not typically been associated with language processing. The high test-retest consistency of MEG evoked activity in the picture naming task testifies to its applicability in clinical evaluations of language function, as well as in longitudinal MEG studies of language production in clinical and healthy populations.

RESUMEN

BACKGROUND: Exchange transfusion is a highly complex procedure that requires high levels of expertise. Trainee paediatricians do not have adequate training in exchange transfusion because opportunities to perform this procedure in practice are scarce. This protocol seeks to compare two educational interventions for exchange transfusion that allow students to develop competencies to perform the technique in an appropriate and safe way. METHODS/DESIGN: This is a randomized parallel single-blind clinical trial with allocation by simple randomization to the educational intervention (simulation or a digital didactic environment). Students from the paediatric specialization who volunteer to participate will be included. A practical evaluation of the procedure will be performed through a simulated scenario using a standardized clinical case. The main outcome is defined as the result of evaluation using the Objective Structured Clinical Examination; superior performance will be defined when the percentage is greater than or equal to 85%, and non-superior performance will be defined when the result is less than 84%. The chi-square independence test or the Fisher exact test will be used to evaluate the effect of the interventions. Multivariate analysis will be performed using a non-conditional logistic regression model. Stata 15® software will be used. DISCUSSION: Exchange transfusion is a procedure that requires expertise to achieve adequate outcomes. The inclusion of new educational strategies, such as simulation and digital didactic environments, is seen as a training option that can improve performance in clinical skills, reduce adverse events and increase the level of trust.

RESUMEN

Interdisciplinary multimodal pain therapy (IMST) is recognized as a scientifically founded form of therapy for inpatient treatment of chronic pain conditions. The indications are assessed by private practitioners and must be confirmed by physicians at the inpatient institution. The health insurance companies are obliged to remunerate this treatment but are allowed to test the conditions in individual cases. Recently, reports from members of the German Pain Society on a drastic increase in testing and rejection quotas have become more frequent. Therefore, this article discusses the legal foundations of the treatment of patients with chronic pain in the inpatient sector. Hard criteria for treatment in a certain sector could not be established. A decision in individual cases will depend on the complexity of the disease in the individual patient. A treatment in hospital is principally only necessary when the treatment corresponds to the generally recognized state of medical knowledge and treatment options in daycase units have not been successful. Important guidance can be found in the treatment guidelines of the medical specialist societies. The transfer to a more intensive treatment sector must be made dependent on the severity and complexity of the symptoms and the insufficient effectiveness of the treatment in the previous sector. Simple ICD-10 diagnoses are not suitable as decision-making criteria and therefore, also not as testing criteria for the indications for inpatient treatment. Decompensated and acutely exacerbated chronic pain conditions must as a rule be treated in hospital, also due to the mental component of the pain disease.

RESUMEN

OBJECTIVE: In the present study, we investigated the attitude of psychiatrists who graduated in 2002-2009 towards Objective Structured Clinical Examination (OSCE) and conventional clinical interview examination (Individual Patient Assessment). METHOD: We studied 134 psychiatrists graduated; half of whom were examined with conventional clinical interview and the others with OSCE. A questionnaire was prepared by a specialist workgroup to assess the participants' attitude towards the exams. The questionnaire was initially examined in a pilot study. The findings of the questionnaire were used to assess the graduates' attitude towards each examination, as well as to compare the examinations. RESULTS: The OSCE group indicated a significantly more positive attitude compared to the conventional group (p = 0.03). Furthermore, the OSCE group believed the role of theoretical knowledge (p = 0.01) and pre-test practice (p = 0.03) to be significantly greater for success compared to the other group. The structure of OSCE was reported to be superior to conventional examination in terms of fairness and homogeneity (p = 0.004). First participation in exam (p = 0.04) and ultimate success in the exam (p = 0.009) were predictors of graduates' attitude. CONCLUSION: Based on examinees 'attitudes, OSCE may be a more appropriate choice for graduation examinations of psychiatry compared to the conventional clinical interview examination.
