Anesthesia and Intensive Care Management for Cardiac Transplantation
Patient management in heart transplant is quite complex and includes multiple steps from preoperative recipient evaluation to postoperative ICU treatment. Monitoring, anesthesia induction, and cardiopulmonary bypass weaning strategies are discussed. The success of the operation also depends on right heart support especially in case of pulmonary hypertension. Many details like fluid management, well-timed respiratory weaning, and primary graft dysfunction management can make the difference in terms of outcome. Pediatric heart transplants represent a small group of total cardiac transplant, but the differences in anatomy and physiology make the surgical and anesthesiological management more complex in unique scenario that requires a specific knowledge at different stages of growth, from newborn through childhood up to adulthood
Reintegração pictórica das pinturas murais da Ermida de Nossa Senhora da Piedade, Loulé: escolhas técnicas
Given its impact on the perception of observers, the reintegration of lacunae in works of pictorial art is one of the most delicate and debated conservation-restoration actions. This text describes the methodology that guided the technical choices regarding the chromatic reintegration of the lacunae and the protective finishing of the mural surfaces in the Nossa Senhora da Piedade (Our Lady of Mercy) Hermitage, in Loulé. Additional reference is made to the way in which those choices/methodology articulated the symbolic and religious values of the hermitage paintings with the ethical and deontological principles of conservation-restoration. Although the type of intervention and its final outcome should always be discussed with the stakeholders, and eventual consultants, technical choices will necessarily be made by the conservator-restorer, who must therefore have training, experience and sensitivity adequate to the critical analysis required by this type of decision making

Ductal ligation timing and neonatal outcomes: a 12-year bicentric comparison.
Funder: Alma Mater Studiorum - Università di BolognaPatent ductus arteriosus (PDA) is common among extremely preterm infants. In selected cases, surgical PDA ligation may be required. The timing for PDA ligation may depend upon a variety of factors, with potential clinical implications. We aimed to investigate the impact of different surgical PDA managements on ligation timing and neonatal outcomes. Inborn infants < 32 weeks of gestation and < 1500 g admitted at two tertiary Neonatal Intensive Care Units that underwent PDA ligation between 2007 and 2018 were enrolled in this retrospective cohort study and split into the following groups based on their surgical management: on-site bedside PDA ligation (ONS) vs. referral to an off-site pediatric cardiac surgery (OFS). Neonatal characteristics, surgical timing, and clinical outcomes of the enrolled infants were compared between the groups. Multivariate analysis was performed to evaluate the impact of PDA ligation timing on significantly different outcomes. Seventy-eight neonates (ONS, n = 39; OFS, n = 39) were included. Infants in the ONS group underwent PDA ligation significantly earlier than those in the OFS group (median age 12 vs. 36 days, p < 0.001) with no increase in postoperative mortality and complications. The multivariate analysis revealed a significant association between PDA ligation timing, late-onset sepsis prevalence (OR 1.045, 0.032), and oxygen need at discharge (OR 1.037, p = 0.025).Conclusions: Compared with off-site surgery, on-site bedside ligation allows an earlier surgical closure of PDA, with no apparent increase in mortality or complications. Earlier PDA ligation may contribute to reduced rates of late-onset sepsis and post-discharge home oxygen therapy, with possible cost-benefit implications. What is known: • Ineffective or contraindicated pharmacological closure of a hemodynamically significant PDA may require a surgical ligation. • Available literature comparing the effect of early vs. late PDA ligation on the main neonatal morbidities has yield contrasting results. What is new: • The availability of a cardiac surgery service performing bedside PDA ligation allows an earlier intervention compared to patient referral to an off-site center, with no difference in postoperative mortality and complications compared to off-site surgery. • Earlier PDA ligation was associated with a lower prevalence of late-onset sepsis and of oxygen need at discharge, with possible cost-benefit implications
