Serial RV wall stress measurements: association with right ventricular function in repaired Tetralogy of Fallot patients.

Background: Optimal timing of pulmonary valve replacement (PVR) in Tetralogy of Fallot (TOF) patients remains challenging. Ventricular wall stress is considered to be an early marker of right ventricular (RV) dysfunction. Objectives: To investigate the association of RV wall stresses and their change over time with functional parameters in TOF patients. Methods: Ten TOF patients after surgical repair with moderate/severe pulmonary regurgitation were included. At two timepoints (median follow-up time 7.2 years), patient-specific computational biventricular models for wall stress assessment were created using CMR short-axis cine images and echocardiography-based RV pressures. RV ejection fraction (RVEF), NT-proBNP and cardiopulmonary exercise tests were used as outcome measures reflecting RV function. Associations between regional RV diastolic wall stress and RV function were investigated using linear mixed models. Results: Increased wall stress correlated with lower RV mass (rrm = -0.70, p = 0.017) and lower RV mass-to-volume (rrm = -0.80, p = 0.003) using repeated measures. Wall stress decreased significantly over time, especially in patients with a stable RVEF (p < 0.001). Higher wall stress was independently associated with lower RVEF, adjusted for left ventricular ejection fraction, RV end-diastolic volume and time since initial surgery (decrease of 1.27% RVEF per kPa increase in wall stress, p = 0.029) using repeated measurements. No association was found between wall stress, NT-proBNP, and exercise capacity. Conclusions: Using a computational method to calculate wall stress locally in geometrically complex ventricles, we demonstrated that lower wall stress might be important to maintain ventricular function. RV wall stress assessment can be used in serial follow-up, and is potentially an early marker of impending RV dysfunction.

[Ethical, deontologic and legal considerations about SIAARTI Document "Clinical ethics recommendations for the allocation of intensive care treatments, in exceptional, resource-limited circumstances".] / Considerazioni etiche, deontologiche e giuridiche sul Documento SIAARTI "Raccomandazioni di etica clinica per l'ammissione a trattamenti intensivi e per la loro sospensione, in condizioni eccezionali di squilibrio tra necessità e risorse disponibili".

On 6 March 2020, the Italian Society of Anaesthesia Analgesia Resuscitation and Intensive care (SIAARTI) published the document "Clinical Ethics Recommendations for Admission to and Suspension of Intensive Care in Exceptional Conditions of Imbalance between Needs and Available Resources". The document, which aims to propose treatment decision-making criteria in the face of exceptional imbalances between health needs and available resources, has produced strong reactions, within the medical-scientific community, in the academic world, and in the media. In the current context of international public health emergency caused by the CoViD-19 epidemic, this work aims to explain the ethical, deontological and legal bases of the SIAARTI Document and to propose methodologic and argumentative integrations that are useful for understanding and placing in context the decision-making criteria proposed. The working group that contributed to the drafting of this paper agrees that it is appropriate that healthcare personnel, who is particularly committed to taking care of those who are currently in need of intensive or sub-intensive care, should benefit from clear operational indications that are useful to orient care and, at the same time, that the population should know in advance which criteria will guide the tragic choices that may fall on each one of us. This contribution therefore firstly reflects on the appropriateness of the SIAARTI standpoint and the objectives of the SIAARTI Document. It then turns to demonstrate how the recommendations it proposes can be framed within a shared interdisciplinary, ethical, deontological and legal perspective.

Emotional concerns and coping strategies in Low Grade Glioma patients and reliability of their caregivers in reporting these concerns: Findings from a cross-sectional study.

PURPOSE: To explore the emotional concerns and coping strategies of patients with Low Grade Glioma (LGG) and whether or not their caregivers are reliable in reporting these concerns as surrogate informants. METHODS: An explorative cross-sectional study. Patients who had undergone a neurosurgical procedure at least one year before this study for LGG and who were capable of participating in a face-to-face interview were included. Each patient nominated a reference caregiver. Both the patient and the caregiver were interviewed independently, using the Beck Depression Inventory Scale, the State - Trait Anxiety Inventory, and the Jalowiec Coping Scale. MAIN RESULTS: Forty-six patients and 46 caregivers were included. The average scores of the Beck scale were homogeneous between patients and caregivers (7.76 [CI 95% 5.76-9.75] vs. 6.23 [CI 95% 4.57-7.90]; p = 0.102). Patients reported significantly greater state and trait anxiety (44.26 [CI 95% 40.21-48.31] and 37.95 [CI 95% 34.97-40.94]), respectively compared to their caregivers (40.28 [CI 95% 36.64-43.91] and 35.17 [CI 95% 32.16-38.18]). The coping strategies enacted were homogeneous between patients and caregivers (82.78 [CI 95% 77.21-88.35] vs (80.93 [CI 95% 76.32-85.55]; p = 0.102) while the kind of strategies adopted were significantly diverse. CONCLUSIONS: Patients suffer from depression and greater state anxiety as compared to trait anxiety; moreover, they enact less than half of the available coping strategies. Caregivers may be involved as surrogate informants when necessary for health-care professionals to detect depression while more caution is advised for what concerns anxiety and the coping strategies enacted by patients.

Validation of a method for noninvasive prenatal testing for fetal aneuploidies risk and considerations for its introduction in the Public Health System.

OBJECTIVE: The aim of this study was to validate noninvasive prenatal testing (NIPT) for fetal aneuploidies by whole-genome massively parallel sequencing (MPS). METHODS: MPS was performed on cell-free DNA (cfDNA) isolated from maternal plasma in two groups: a first set of 186 euploid samples and a second set of 195 samples enriched of aneuploid cases (n = 69); digital PCR for fetal fraction (FF) assessment was performed on 178/381 samples. Cases with <10 × 106 reads (n = 54) were excluded for downstream data analysis. Follow-up data (invasive testing results or neonatal information) were available for all samples. Performances in terms of specificity/sensitivity and Z-score distributions were evaluated. RESULTS: All positive samples for trisomy 21 (T21) (n = 43), trisomy 18 (T18) (n = 6) and trisomy 13 (T13) (n = 7) were correctly identified (sensitivity: 99.9%); 5 false positive results were reported: 3 for T21 (specificity = 98.9%) and 2 for T13 (specificity = 99.4%). Besides FF, total cfDNA concentration seems another important parameter for MPS, since it influences the number of reads. CONCLUSIONS: The overall test accuracy allowed us introducing NIPT for T21, T18 and T13 as a clinical service for pregnant women after 10 + 4 weeks of gestation. Sex chromosome aneuploidy assessment needs further validation due to the limited number of aneuploid cases in this study.
