RESUMEN
OBJECTIVE: Peripheral regional anesthesia is proposed to enhance recovery. We sought to evaluate the efficacy of bilateral continuous erector spinae plane blocks (B-ESpB) for postoperative analgesia and the impact on recovery in children undergoing cardiac surgery. METHODS: Patients aged 2 through 17 years undergoing cardiac surgery in the enhanced recovery after cardiac surgery program were prospectively enrolled to receive B-ESpB at the end of the procedure, with continuous infusions via catheters postoperatively. Participants wore an activity monitor until discharge. B-ESpB patients were retrospectively matched with control patients in the enhanced recovery after cardiac surgery program. Outcomes of the matched clusters were compared using exact conditional logistic regression and generalized linear modeling. RESULTS: Forty patients receiving B-ESpB were matched to 78 controls. There were no major complications from the B-ESpB or infusions, and operating room time was longer by a median of 31 minutes. While blocks were infusing, patients with B-ESpB received fewer opioids in oral morphine equivalents than controls at 24 hours (0.60 ± 0.06 vs 0.78 ± 0.04 mg/kg; P = .02) and 48 hours (1.13 ± 0.08 vs 1.35 ± 0.06 mg/kg; P = .04), respectively. Both groups had low median pain scores per 12-hour period. There was no difference in early mobilization, length of stay, or complications. CONCLUSIONS: B-ESpBs are safe in children undergoing cardiac surgery. When performed as part of a multimodal pain strategy in an enhanced recovery after cardiac surgery program, pediatric patients with B-ESpB experience good pain control and require fewer opioids in the first 48 hours.
RESUMEN
Background: Respiratory syncytial virus (RSV) is a contagious pathogen causing acute respiratory infections (ARIs). Symptoms range from mild upper respiratory tract infections to potentially life-threatening lower respiratory tract disease (LRTD). In adults ≥60 years old, vaccine efficacy of a candidate vaccine for older adults (RSVPreF3 OA) was 71.7% against RSV-ARI and 82.6% against RSV-LRTD (AReSVi-006/NCT04886596). We present the patient-reported outcomes (PROs) from the same trial at the end of the first RSV season in the northern hemisphere (April 2022). Methods: In this phase 3 trial, adults aged ≥60 years were randomized (1:1) to receive one dose of RSVPreF3 OA vaccine or placebo. PROs were assessed using InFLUenza Patient-Reported Outcome (FLU-PRO), Short Form-12 (SF-12), and EuroQol-5 Dimension (EQ-5D) questionnaires. Peak FLU-PRO Chest/Respiratory scores during the first 7 days from ARI episode onset were compared using a Wilcoxon test. Least squares mean (LSMean) of SF-12 physical functioning (PF) and EQ-5D health utility scores were estimated using mixed effects models. Results: In the RSVPreF3 OA group (N = 12,466), 27 first RSV-ARI episodes were observed versus 95 in the Placebo group (N = 12,494). Median peak FLU-PRO Chest/Respiratory scores were lower in RSVPreF3 OA (1.07) versus Placebo group (1.86); p = 0.0258. LSMean group differences for the PF and EQ-5D health utility score were 7.00 (95% confidence interval [CI]: -9.86, 23.85; p = 0.4125) and 0.0786 (95% CI: -0.0340, 0.1913; p = 0.1695). Conclusions: The RSVPreF3 OA vaccine, in addition to preventing infection, attenuated the severity of RSV-associated symptoms in breakthrough infections, with trends of reduced impact on PF and health utility.

The spatial-temporal distribution pattern of St. Lawrence Estuary (SLE) beluga is examined with a passive acoustic monitoring network of 13 stations from June 2018 to October 2021. A beluga calling index, correlated with beluga density, is used as a proxy for habitat use by the population at weekly, monthly, and yearly scales. The seasonal pattern along SLE upstream-downstream axis was repeated annually. In summer, beluga habitat was confined to a 150 km segment of the SLE, with higher occurrences in its â¼20 km central portion, including the head of the Laurentian Channel and Saguenay Fjord mouth. During fall, the distribution gradually shifted to the downstream portion of the SLE and into the Northwestern Gulf, leaving low to no occurrences upstream in winter, until the spring return, characterized by the highest upstream occurrences. Occurrences off Ste. Marguerite Bay, 25 km upstream in Saguenay Fjord, were essentially from June to October. This multi-year continuous habitat use pattern provides a baseline for year-round SLE beluga distribution dynamics for assessing and mitigating anthropogenic threats to this endangered population, such as shipping noise. It also provides insights for optimizing the assessments of population size from aerial line transect surveys.
RESUMEN
Undernutrition in residents of residential care facilities for the dependent elderly can be managed by oral nutritional supplements (ONS). The objective of this study is to evaluate their proper use. A total of 41.9% of residents on NOCs were malnourished on the day of the audit, compared with 71.5% before the introduction of NOCs. NOCs were administered according to the dietician's prescription, which differed from the doctor's prescription in more than half of the cases. NOCs were fully consumed by 79.2% of residents.

Background: The Society of Thoracic Surgeons Workforce on Critical Care and the Extracorporeal Life Support Organization sought to identify how the coronavirus disease 2019 (COVID-19) pandemic has changed the practice of venoarterial (VA) and venovenous (VV) extracorporeal membrane oxygenation (ECMO) programs across North America. Methods: A 26-question survey covering 6 categories (ECMO initiation, cannulation, management, anticoagulation, triage/protocols, and credentialing) was emailed to 276 North American Extracorporeal Life Support Organization centers. ECMO practices before and during the COVID-19 pandemic were compared. Results: Responses were received from 93 (34%) programs. The percentage of high-volume (>20 cases per year) VV ECMO programs increased during the pandemic from 29% to 41% (P < .001), as did institutions requiring multiple clinicians for determining initiation of ECMO (VV ECMO, 25% to 43% [P = .001]; VA ECMO, 20% to 32% [P = .012]). During the pandemic, more institutions developed their own protocols for resource allocation (23% before to 51%; P < .001), and more programs created sharing arrangements to triage patients and equipment with other centers (31% to 57%; P < .001). Direct thrombin inhibitor use increased for both VA ECMO (13% to 18%; P = .025) and VV ECMO (12% to 24%; P = .005). Although cardiothoracic surgeons remained the primary cannulating proceduralists, VV ECMO cannulations performed by pulmonary and critical care physicians increased (13% to 17%; P = .046). Conclusions: The Society of Thoracic Surgeons/Extracorporeal Life Support Organization collaborative survey indicated that the pandemic has affected ECMO practice. Further research on these ECMO strategies and lessons learned during the COVID-19 pandemic may be useful in future global situations.
RESUMEN
BACKGROUND: Post-operative nausea and vomiting is frequent after congenital cardiac surgery. AIMS: We sought to determine factors associated to severe post-operative vomiting after congenital cardiac surgery and the effect on post-operative outcomes. METHODS: Patients > 30 days of age who underwent elective cardiac surgical repair as part of an enhanced recovery after congenital cardiac surgery programme were retrospectively reviewed. Patient characteristics and perioperative factors were compared by univariate analysis for patients with severe post-operative vomiting, defined as three events or more, and for patients with no-or-mild post-operative vomiting. All variables with a p-value < 0.1 were included in a multivariable model, and major post-operative outcomes were compared using regression analysis. RESULTS: From 1 October, 2018 to 30 September, 2019, 430 consecutive patients were included. The median age was 4.8 years (interquartile range 1.2-12.6). Twenty-one per cent of patients (91/430) experienced severe post-operative vomiting. Total intraoperative opioids > 5.0 mg/kg of oral morphine equivalent (adjusted odds ratio 1.72) and post-operative inotropes infusion(s) (adjusted odds ratio 1.64) were identified as independent predictors of severe post-operative vomiting after surgery. Patients suffering from severe post-operative vomiting had increased pulmonary complications (adjusted odds ratio 5.18) and longer post-operative hospitalisation (adjusted coefficient, 0.89). CONCLUSIONS: Greater cumulative intraoperative opioids are associated with severe post-operative vomiting after congenital cardiac surgery. Multimodal pain strategies targeting the reduction of intraoperative opioids should be considered during congenital cardiac surgery to enhance recovery after surgery.

For yet another year, our lives have been dominated by a pandemic. This year in review, we feature an expert panel opinion regarding extracorporeal support in the context of COVID-19, challenging previously held standards. We also feature survey results assessing the impact of the pandemic on cardiac surgical volume. Furthermore, we focus on a single center experience that evaluated the use of pulmonary artery catheters and the comparison of transfusion strategies in the Restrictive and Liberal Transfusion Strategies in Patients With Acute Myocardial Infarction (REALITY) trial. Additionally, we address the impact of acute kidney injury on cardiac surgery and highlight the controversy regarding the choice of fluid resuscitation. We close with an evaluation of dysphagia in cardiac surgery and the impact of prehabilitation to optimize surgical outcomes.

Context: Palmar striated xanthomas (PSX) are macular subcutaneous lesions conferring a yellow-to-orange coloration of palmar and finger creases that characterize dysbetalipoproteinemia, a disease associated with sustained plasma accumulation of triglyceride-rich lipoprotein remnants. Although remnants accumulation may occur in any condition interfering with triglyceride-rich lipoprotein hydrolysis or clearance, the presence of PSX has not been systematically assessed across the spectrum of lipid disorders potentially associated with sustained or recurrent remnants accumulation. Objective: The aim of this study was to assess the occurrence of (PSX) in a wide spectrum of lipid disorders ranging from very severe hypercholesterolemia (homozygous familial hypercholesterolemia) to very severe hypertriglyceridemia (chylomicronemia). Methods: This study involved 3382 dyslipidemic White adult patients (1856 men and 1526 women) seen at the Chicoutimi Hospital Lipid Clinic (Quebec, Canada), covering a wide range of lipid disorders, from severe hypertriglyceridemia to severe hypercholesterolemia. Categorical variables were compared using the Pearson χâ2 statistic, whereas univariate analysis of variance or nonparametric Kruskal-Wallis was used for continuous variables. Results: A total of 5.1% (173/3382) of the studied patients presented PSX, a majority of them (67.1%) being women. PSX were observed in 18.8% of patients with dysbetalipoproteinemia and also among 14.1% of hypertriglyceridemic patients with partial lipoprotein lipase deficiency, 3.7% of patients with chylomicronemia, and in all those with homozygous familial hypercholesterolemia. Overall, 10.7% of patients with PSX did not meet dysbetalipoproteinemia diagnosis criteria. Conclusion: According to our study, the PSX prevalence estimate among patients without dysbetalipoproteinemia would be around 10% and they could be observed in a wide spectrum of lipid disorders associated with recurrent or sustained remnant lipoprotein accumulation.
RESUMEN
OBJECTIVES: Disparities in perioperative outcomes exist. In addition to patient and socioeconomic factors, racial disparities in outcome measures may be related to issues at the provider and institutional levels. Recognizing a potential role of standardized care in mitigating provider bias, this study aims to compare the perioperative sedation and pain management and consequent outcomes in Enhanced Recovery After Surgery (ERAS) cardiac patients of different races undergoing congenital heart surgery at a single quaternary children's hospital. DESIGN: A retrospective study. SETTING: A single quaternary pediatric hospital. PARTICIPANTS: Patients, infants to adults, undergoing elective congenital cardiac surgery and enrolled in the ERAS protocol from October 2018 to December 2020. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Of the patients, 872 were reviewed and 606 with race information were analyzed. There was no significant difference in intraoperative and postoperative oral morphine equivalent, perioperative sedatives, and regional blockade in Asian or African American patients when compared to White patients. Postoperative pain scores and outcomes among African American and Asian races were also not statistically different when compared to White patients. CONCLUSIONS: Racial disparity in perioperative management and outcomes in patients with standardized ERAS protocols does not exist at the authors' institution. Future comparative studies of ERAS noncardiac patients may provide additional information on the role of standardization in reducing implicit bias.

BACKGROUND: The benefits of a comprehensive enhanced recovery after surgery (ERAS) program for patients with congenital heart disease are largely unknown. This study evaluated adherence and to outcomes of a recently implemented enhanced recovery program (ERP) in congenital cardiac surgery. METHODS: Patients undergoing elective procedures for simple and moderately complex congenital cardiac surgery have followed institutional ERP guidelines since October 2018. Adherence to guidelines over a 12-month period (P2) was compared with implementation data (P1, 5 months). The association of outcomes with continuous time was estimated using linear regression. RESULTS: Among 559 patients (representing 40% of the cardiac surgical volume) following the ERP over a period of 17 months, no differences in patient characteristics were observed between periods, except a higher incidence of previous operations in P2. Adherence to many aspects of guidelines improved from P1 to P2. The following improvements were notable: operating room extubation, 27% in P2 vs16% in P1 (P = .006); and a decrease in median ventilation time, 6.0 hours (interquartile range [IQR], 0-9.2 hours) in P2 vs 7.6 hours (IQR, 3.8-12.3 hours) in P1 (P = .002). In addition, there was a reduction in opioids, reported as oral morphine equivalents, that was most significant for intraoperative oral morphine equivalents: 5.00 mg/kg (IQR, 3.11-7.60 mg/kg) in P2 vs 6.05 mg/kg (IQR, 3.77-9.78 mg/kg) in P1 (P = .001). There was no difference in overall intensive care unit and postoperative lengths of stay, except in lower-risk surgical procedures. Surgical outcomes were similar in the 2 periods. CONCLUSIONS: An enhanced recovery program reduced the use of opioids, led to more extubation in the operating room, and reduced mechanical ventilation duration in patients undergoing congenital cardiac surgery.

The AngioVac System (AVS) extracts venous and pulmonary artery (PA) thrombi. We report modified use of the second-generation AVS with concurrent venoarterial extracorporeal membrane oxygenation (VA-ECMO) in a 10-year-old, 23 kg patient with failing Fontan circulation due to acute-on-chronic Fontan and PA thrombosis. Emergent femoral VA-ECMO was initiated for profound hypoxemia during cardiac catheterization. Fluoroscopy-guided thrombo-embolectomy was performed with AVS components. A two-venous limb inflow cannulation strategy was used; the AngioVac cannula (AVC) was positioned in the central PA and joined to the existing ECMO venous-limb. Thrombus extraction proceeded by clamping the ECMO venous-limb with the existing VA-ECMO centrifugal pump generating negative pressure to the AVC. Extracorporeal membrane oxygenation arterial-limb access was used for blood return. Settings to avoid cavitation were a maximal negative pressure of 100 mmHg using <3500 RPMs. To access the branch PAs, the AVC was replaced by a custom-modified 17 Fr arterial ECMO cannula. Clot retrieval was sufficient for improved clinical status enabling ECMO discontinuation within 24-hours, and discharge home 26-days later. This is the first description of successful subtotal thrombo-embolectomy with AVS components in a child with Fontan physiology concurrently supported on VA-ECMO, using one centrifugal pump. Although feasible, circuit modifications and close monitoring are required to avoid complications.

The avian eggshell is a remarkable biomineral, which is essential for avian reproduction; its properties permit embryonic development in the desiccating terrestrial environment, and moreover, are critically important to preserve unfertilized egg quality for human consumption. This calcium carbonate (CaCO3) bioceramic is made of 95% calcite and 3.5% organic matrix; it protects the egg contents against microbial penetration and mechanical damage, allows gaseous exchange, and provides calcium for development of the embryonic skeleton. In vertebrates, eggshell occurs in the Sauropsida and in a lesser extent in Mammalia taxa; avian eggshell calcification is one of the fastest known CaCO3 biomineralization processes, and results in a material with excellent mechanical properties. Thus, its study has triggered a strong interest from the researcher community. The investigation of eggshell biomineralization in birds over the past decades has led to detailed characterization of its protein and mineral constituents. Recently, our understanding of this process has been significantly improved using high-throughput technologies (i.e., proteomics, transcriptomics, genomics, and bioinformatics). Presently, more or less complete eggshell proteomes are available for nine birds, and therefore, key proteins that comprise the eggshell biomineralization toolkit are beginning to be identified. In this article, we review current knowledge on organic matrix components from calcified eggshell. We use these data to analyze the evolution of selected matrix proteins and underline their role in the biological toolkit required for eggshell calcification in avian species. Amongst the panel of eggshell-associated proteins, key functional domains are present such as calcium-binding, vesicle-binding and protein-binding. These technical advances, combined with progress in mineral ultrastructure analyses, have opened the way for new hypotheses of mineral nucleation and crystal growth in formation of the avian eggshell, including transfer of amorphous CaCO3 in vesicles from uterine cells to the eggshell mineralization site. The enrichment of multi-omics datasets for bird species is critical to understand the evolutionary context for development of CaCO3 biomineralization in metazoans, leading to the acquisition of the robust eggshell in birds (and formerly dinosaurs).
RESUMEN
BACKGROUND: Extracorporeal cardiopulmonary resuscitation (ECPR) has emerged as a rescue strategy for nonresponders to conventional CPR (CCPR) in cardiac arrest. Definitive guidelines for ECPR deployment do not exist. Prior studies suggest that arrest rhythm and cardiac origin of arrest may be variables used to assess candidacy for ECPR. AIM: To describe a single-center experience with ECPR and to assess associations between survival and physician-adjudicated origin of arrest and arrest rhythm. METHODS: A retrospective review of all patients who underwent ECPR at a quaternary care center over a 7-year period was performed. Demographic and clinical characteristics were extracted from the medical record and used to adjudicate the origin of cardiac arrest, etiology, rhythm, survival, and outcomes. Univariate analysis was performed to determine the association of patient and arrest characteristics with survival. RESULTS: Between 2010 and 2017, 47 cardiac arrest patients were initiated on extracorporeal membrane oxygenation (ECMO) at the time of active CPR. ECPR patient survival to hospital discharge was 25.5% (n = 12). Twenty-six patients died on ECMO (55.3%) while nine patients (19.1%) survived decannulation but died before discharge. Neither physician-adjudicated arrest rhythm nor underlying origin were significantly associated with survival to discharge, either alone or in combination. Younger age was significantly associated with survival. Nearly all survivors experienced myocardial recovery and left the hospital with a good neurological status. CONCLUSIONS: Arrest rhythm and etiology may be insufficient predictors of survival in ECPR utilization. Further multiinstitutional studies are needed to determine evidenced-based criteria for ECPR deployment.

BACKGROUND: The process of calcium carbonate biomineralization has arisen multiple times during metazoan evolution. In the phylum Cnidaria, biomineralization has mostly been studied in the subclass Hexacorallia (i.e. stony corals) in comparison to the subclass Octocorallia (i.e. red corals); the two diverged approximately 600 million years ago. The precious Mediterranean red coral, Corallium rubrum, is an octocorallian species, which produces two distinct high-magnesium calcite biominerals, the axial skeleton and the sclerites. In order to gain insight into the red coral biomineralization process and cnidarian biomineralization evolution, we studied the protein repertoire forming the organic matrix (OM) of its two biominerals. RESULTS: We combined High-Resolution Mass Spectrometry and transcriptome analysis to study the OM composition of the axial skeleton and the sclerites. We identified a total of 102 OM proteins, 52 are found in the two red coral biominerals with scleritin being the most abundant protein in each fraction. Contrary to reef building corals, the red coral organic matrix possesses a large number of collagen-like proteins. Agrin-like glycoproteins and proteins with sugar-binding domains are also predominant. Twenty-seven and 23 proteins were uniquely assigned to the axial skeleton and the sclerites, respectively. The inferred regulatory function of these OM proteins suggests that the difference between the two biominerals is due to the modeling of the matrix network, rather than the presence of specific structural components. At least one OM component could have been horizontally transferred from prokaryotes early during Octocorallia evolution. CONCLUSION: Our results suggest that calcification of the red coral axial skeleton likely represents a secondary calcification of an ancestral gorgonian horny axis. In addition, the comparison with stony coral skeletomes highlighted the low proportion of similar proteins between the biomineral OMs of hexacorallian and octocorallian corals, suggesting an independent acquisition of calcification in anthozoans.
