Extending the concept of moral distress to parents of infants hospitalized in the NICU: a qualitative study in Greece.

BACKGROUND: The hospitalization of infants in the neonatal intensive care unit (NICU) is an ethically challenging situation. A limited number of studies have extended the concept of moral distress to parents of infants hospitalized in the NICU. This topic requires further investigation. METHODS: The present prospective qualitative study was conducted from February 2023 to May 2023. Data were collected through semistructured in-depth interviews, which were conducted in-person with fifteen parents of infants who were hospitalized in the NICU at the time of the interviews. Purposive sampling was used. The data were classified and analyzed using thematic analysis. RESULTS: Three themes emerged from the data analysis performed for this empirical study. One intrapersonal dimension featuring two aspects (one dynamic and one static) and another interpersonal dimension focusing on parental moral distress emerged from the data analysis. Furthermore, seven subthemes emerged across these themes: (1) self-directed negative feelings were experienced by parents due to their inability to fulfill their caregiving/parental roles; (2) intense internal conflict was experienced by parents in response to a moral dilemma that was difficult, which was perceived as irresolvable; (3) objectively unjustified, self-directed negative feelings of guilt or failure were experienced by parents; (4) parents experienced moral distress due to the poor image of the ill infants; (5) inadequate information may predispose parents to experience moral distress (6) neonatologists' caring behaviors were unduly perceived by parents as paternalistic behaviors; (7) reasonable or justified institutional rules were unduly perceived by parents as constraint. CONCLUSIONS: In general, the results of this study support the integrated definition of parental moral distress proposed by Mooney-Doyle and Ulrich. Furthermore, the present study introduces new information. The study distinguishes between the dynamic and static aspects of the intrapersonal dimension of the phenomenon of parental moral distress. Moreover, participants experienced moral distress because they unduly perceived certain situations as causing moral distress. In addition, inadequate information may predispose parents to experience moral distress. The findings of this study may contribute promote family-centered care in the NICU context.

Moral distress among neonatologists working in neonatal intensive care units in Greece: a qualitative study.

BACKGROUND: Working as a neonatologist in a neonatal intensive care unit (NICU) is stressful and involves ethically challenging situations. These situations may cause neonatologists to experience high levels of moral distress, especially in the context of caring for extremely premature infants (EPIs). In Greece, moral distress among neonatologists working in NICUs remains understudied and warrants further exploration. METHODS: This prospective qualitative study was conducted from March to August 2022. A combination of purposive and snowball sampling was used and data were collected by semi-structured interviews with twenty neonatologists. Data were classified and analyzed by thematic analysis approach. RESULTS: A variety of distinct themes and subthemes emerged from the analysis of the interview data. Neonatologists face moral uncertainty. Furthermore, they prioritize their traditional (Hippocratic) role as healers. Importantly, neonatologists seek third-party support for their decisions to reduce their decision uncertainty. In addition, based on the analysis of the interview data, multiple predisposing factors that foster and facilitate neonatologists' moral distress emerged, as did multiple predisposing factors that are sometimes associated with neonatologists' constraint distress and sometimes associated with their uncertainty distress. The predisposing factors that foster and facilitate neonatologists' moral distress thus identified include the lack of previous experience on the part of neonatologists, the lack of clear and adequate clinical practice guidelines/recommendations/protocols, the scarcity of health care resources, the fact that in the context of neonatology, the infant's best interest and quality of life are difficult to identify, and the need to make decisions in a short time frame. NICU directors, neonatologists' colleagues working in the same NICU and parental wishes and attitudes were identified as predisposing factors that are sometimes associated with neonatologists' constraint distress and sometimes associated with their uncertainty distress. Ultimately, neonatologists become more resistant to moral distress over time. CONCLUSIONS: We concluded that neonatologists' moral distress should be conceptualized in the broad sense of the term and is closely associated with multiple predisposing factors. Such distress is greatly affected by interpersonal relationships. A variety of distinct themes and subthemes were identified, which, for the most part, were consistent with the findings of previous research. However, we identified some nuances that are of practical importance. The results of this study may serve as a starting point for future research.

A qualitative study of nursing practitioners' experiences with COVID-19 patients dying alone in Greece.

Background: In Greece, there is still limited research on death in isolation due to COVID-19. This deserves attention because of the recent financial crisis, which profoundly impacted public health, and the high relevance of the Hippocratic tradition to the moral values of clinical practice. Methods: A prospective qualitative study using in-depth interviews with 15 frontline nursing practitioners working in a COVID-19 ward or intensive care unit (ICU) was conducted from July 2021 to December 2021. Results: The inability of family members to say a final goodbye before, during, or after death by performing proper mourning rituals is extremely inhuman and profoundly impacts the mental health status of patients, family members, and nursing practitioners. Patients and their family members strongly desire to see each other. Epidemiology, liability, and proper nursing performance emerged as reasons for the enforced strict visitation restrictions. Participants emphasized that visitations should be allowed on an individual basis and highlighted the need for the effective use of remote communication technology, which, however, does not substitute for in-person contact. Importantly, physicians allowed "clandestine" visits on an individual basis. Nursing practitioners had a strong empathic attitude toward both patients and their families, and a strong willingness to provide holistic care and pay respect to dead bodies. However, they also experienced moral distress. Witnessing heartbreaking scenes with patients and/or their families causes nursing practitioners to experience intense psychological distress, which affects their family life rather than nursing performance. Ultimately, there was a shift from a patient-centered care model to a population-centered care model. Furthermore, we identified a range of policy- and culture-related factors that exaggerate the negative consequences of dying alone of COVID-19. Conclusion: These results reinforce the existing literature on several fronts. However, we identified some nuances related to political decisions and, most importantly, convictions that are deeply rooted in Greek culture. These findings are of great importance in planning tailored interventions to mitigate the problem of interest and have implications for other similar national contexts.

The Adjunctive Use of Leucocyte- and Platelet-Rich Fibrin in Periodontal Endosseous and Furcation Defects: A Systematic Review and Meta-Analysis.

The aim of this systematic review of randomized controlled trials was to evaluate the adjunctive use of leucocyte- and platelet-rich fibrin (L-PRF) in periodontal endosseous and furcation defects, as compared without L-PRF. The endosseous defect group was subclassified into: L-PRF/open flap debridement (L-PRF/OFD) versus OFD, L-PRF/osseous graft (L-PRF/OG) versus OG, L-PRF/Emdogain (L-PRF/EMD) versus EMD, and L-PRF/guided tissue regeneration (L-PRF/GTR) versus GTR. The furcation defect group was subclassified into L-PRF/OFD versus OFD, and L-PRF/OG versus OG. Mean difference, 95% confidence intervals and forest plots were calculated for probing pocket depth (PPD), clinical attachment level (CAL) and radiographic defect depth (DD). Nineteen studies concerning systemically healthy non-smokers were included. The results of this systematic review and meta-analysis showed in two- and/or three-wall endosseous defects that the adjunctive use of L-PRF to OFD or OG was significantly beneficial for PPD reduction, CAL gain and DD reduction, as compared without L-PRF. Furthermore, the data showed that for two- and/or three-wall endosseous defects, the adjunctive use of L-PRF to GTR was significantly beneficial for CAL and DD improvement, whereas adding L-PRF to EMD had no significant effect, and that for class II furcation defects, the addition of L-PRF to OFD was significantly beneficial for PPD, CAL and DD improvement, whereas the addition of L-PRF to OG was significantly clinically beneficial. In conclusion, this systematic review and meta-analysis found that there was significant clinical and radiographic additive effectiveness of L-PRF to OFD and to OG in two- and/or three-wall periodontal endosseous defects of systemically healthy non-smokers, as compared without L-PRF.

Histopathology of thymectomy specimens from the MGTX-trial: Entropy analysis as strategy to quantify spatial heterogeneity of lymphoid follicle and fat distribution.

The thymectomy specimens from the "thymectomy trial in non-thymomatous myasthenia gravis patients receiving prednisone therapy" (MGTX) underwent rigid and comprehensive work-up, which permits analysis of the spatial distribution of histological and immunohistological features. This analysis revealed strong intra- and inter-case variability. While many histological features (e.g. median percent fat content among different specimens) can easily be correlated with clinical parameters, intra-case spatial variability of histological features has yet defied quantification and statistical evaluation. To overcome this gap in digital pathology, we here propose intra-case entropy of measured histological features in all available slides of a given thymectomy specimen as a quantitative marker of spatial histological heterogeneity. Calculation of entropy led to one value per specimen and histological feature. Through these 'entropy values' the so far neglected degree of spatial histological heterogeneity could be fed into statistical analyses, extending the scope of clinico-pathological correlations.

Tailoring naringenin conjugates with amplified and triple antiplatelet activity profile: Rational design, synthesis, human plasma stability and in vitro evaluation.

BACKGROUND: The current standard-of-care antiplatelet therapy in cardiovascular disease patients is consisted of cyclooxygenase-1 (COX-1) inhibitor aspirin, along with a platelet receptor P2Y12 antagonist. Recently, the triple antiplatelet therapy with aspirin, a P2Y12 receptor antagonist and a protease activated receptor-1 (PAR-1) antagonist, has been suggested for the secondary prevention of atherothrombotic events, however presented an increased risk of bleeding. Therefore, the quest for novel antiplatelet agents simultaneously targeting the three pathways with improved efficacy/safety profile is of immense importance. Flavonoids as pre-validated ligands for numerous targets could serve as scaffolds targeting the three platelet activation pathways. METHODS: Computational methods, Ultra High Performance Liquid Chromatography-Tandem Mass Spectrometry (UHPLC-MS/MS) plasma stability and in vitro platelet aggregation experiments were used to establish the antiplatelet activity of the flavonoid naringenin and its conjugates. RESULTS: In silico studies indicated that naringenin could bear a potent triple antiplatelet activity by inhibiting different platelet aggregation mechanisms. However, we found that in human platelets naringenin has diminished activity. We rationally designed and synthesized different naringenin conjugates aiming to amplify the antiplatelet activity of the parent compound. UHPLC-MS/MS revealed a slow degradation rate for a docosahexaenoic acid (DHA) - naringenin conjugate in human plasma. The antiplatelet profile of the new analogues was evaluated against in vitro platelet aggregation induced by several platelet agonists. CONCLUSIONS: The DHA - naringenin hybrid presented triple antiplatelet activity simultaneously targeting PAR-1, P2Y12 and COX-1 platelet activation pathways. GENERAL SIGNIFICANCE: Natural products could offer a rich source for novel bioactives as a powerful alternative to the current combinatorial use of three different antiplatelet drugs.
