Abstract
Continuous renal replacement therapies (CRRT) affect hemodynamics and urine output. Some theories suggest a reduced renal blood flow as the cause of the decreased urine output, but the exact mechanisms remain unclear. A prospective experimental study was carried out in 32 piglets (2–3 months old) in order to compare the impact of CRRT on hemodynamics, renal perfusion, urine output and renal function in healthy animals and in those with non-oliguric acute kidney injury (AKI). CRRT was started according to our clinical protocol, with an initial blood flow of 20 ml/min, with 10 ml/min increases every minute until a goal flow of 5 ml/kg/min. Heart rate, blood pressure, central venous pressure, cardiac output, renal blood flow and urine output were registered at baseline and during the first 6 h of CRRT. Blood and urine samples were drawn at baseline and after 2 and 6 h of therapy. Blood pressure, cardiac index and urine output significantly decreased after starting CRRT in all piglets. Renal blood flow, however, steadily increased throughout the study. Cisplatin piglets had lower cardiac index, higher vascular resistance, lower renal blood flow and lower urine output than control piglets. Plasma levels of ADH and urine levels of aquaporin-2 were lower, whereas kidney injury biomarkers were higher in the cisplatin group of piglets. According to our findings, a reduced renal blood flow doesn’t seem to be the cause of the decrease in urine output after starting CRRT.

Abstract
Clostridioides difficile is a nosocomial, Gram-positive, strictly anaerobic, spore-forming pathogen capable of colonizing and proliferating in the human intestine. In bacteria, it has been shown that the Toxin-Antitoxin systems mediate the cellular response to external stress by initiating processes such as biofilm formation and programmed cell death. This work aims to evaluate the functionality of four type II TA modules of Clostridioides difficile R20291. We performed bioinformatic analysis to search for putative TA systems using the TADB platform. Then we performed a heterologous expression assay to evaluate the functionality of these systems. Our results showed that the MazEF and RelBE systems were functional, suggesting that their corresponding toxins possess an endoribonuclease activity. In conclusion, MazEF and RelBE systems of C. difficile R20291 are functional in a heterologous expression system.

Abstract
Background Post-extubation upper airway obstruction (UAO) is a frequent complication causing stridor and respiratory distress, which occasionally require reintubation, thereby increasing morbidity and mortality rates. Contradictory results have been obtained in studies assessing the effectiveness of steroids in preventing post-extubation UAO, and the available evidence is limited. We designed a multicentric randomized, placebo-controlled study to explore the effectiveness of dexamethasone in preventing post-extubation UAO in children. Methods A multicentric, prospective, double-blind, randomized, placebo-controlled, phase IV clinical trial has been designed. The sample will include pediatric patients who are between 1 month and 16 years of age and who have been intubated for more than 48 h. Patients who have airway disorders or who have received steroids within the previous seven days will be excluded. Patients will be randomly assigned to receive either placebo or a therapy with dexamethasone 0.25 mg/kg every 6 h to be started 6 to 12 h prior to extubation (to a total of four doses). Randomization will be performed at a 1:1 ratio. Follow-up of patients will be carried out for 48 h after extubation. The main objective of this study is to access the reduction in the incidence of moderate to severe UAO symptoms following extubation. Secondary objectives include assessing the decrease in the incidence of reintubation, evaluating the use of additional therapies for UAO, and monitoring potential side effects of dexamethasone. Discussion The results of this study will contribute to the existing evidence on prophylaxis for post-extubation airway obstruction. Trial registration EudraCT identifier: 2009–016596-30.

Abstract
OBJECTIVES To compare the incidence of permanent pacemaker implantation (PPI) with the CoreValve and Evolut R prostheses, to evaluate the implantation depth with both types of prostheses, and to study factors predicting the need for PPI. BACKGROUND The Evolut R CoreValve can be recaptured and repositioned during deployment, allowing a more precise implantation. METHODS A total of 208 patients treated with CoreValve and 137 patients treated with Evolut R were analyzed. The depth of the prosthesis in the LVOT was measured by angiography in the annular perpendicular view projection after deploymen in all patients. RESULTS Baseline conduction abnormalities were comparable between the groups (85/208, 40.9% vs. 53/137, 38.7%; p = 0.69). The mean prosthesis depth was 10.3 ± 8.6 mm in the CoreValve group and 5.5 ± 2.7 mm in the Evolut R group; p < 0.0001. Conduction disturbances after valve implantation were more frequent with the CoreValve (new-onset left bundle branch block: 93, 44.7% vs. 16, 11.7%; p < 0.05, first-degree atrioventricular block: 23, 11.1% vs. 5, 3.6%; p < 0.05). In addition, the incidence of PPI was significantly lower with Evolut R (45, 21.6% vs. 15, 10.9%; p = 0.01). The predictors of the need for PPI were the mean depth of the prosthesis (OR: 1.13, 95% CI: 1.06-1.21; p < 0.0001) and prior right bundle branch block (OR 10.22, 95% CI: 4.62-22.63; p < 0.0001). CONCLUSIONS The recapturable capability of the Evolut R system allowed for higher and precise valve implantation. This fact had an impact on the reduction in the need for PPI.

Abstract
INTRODUCTION It has been suggested that neuromuscular blockade (NMB) affects the capacity of bispectral index (BIS) monitoring to measure consciousness in sedated children. Our aim was to analyse the impact of NMB on BIS values in critically ill children. METHODS We conducted a prospective observational study of children monitored with a BIS system that received a continuous infusion of vecuronium. We analysed data on clinical, diagnostic and haemodynamic variables, sedatives, analgesics, muscle relaxants, and BIS parameters. We compared BIS parameters before the use of a muscle relaxant, during its administration, before its discontinuation and for the 24h following the end of the infusion. RESULTS The analysis included 35 patients (median age, 30 months). The most common diagnosis was heart disease (85%). The most frequent indication for initiation of NMB was low cardiac output (45%), followed by adaptation to mechanical ventilation (20%). Neuromuscular blockade did not produce a significant change in BIS values. We found a decrease was observed in electromyography (EMG) values at 6h (34.9±9.4 vs 31.2±7; P=.008) and 12h after initiation of NMB (34.9±9.4 vs 28.6±4.8; P =.006). We observed a small significant increase in BIS after discontinuation of NMB (from 42.7±11 to 48.4±14.5, P=.001), and 6 and 12h later (51.3±16.6; P=.015). There were no differences in the doses of sedatives or analgesics except for fentanyl, of which the dose was lowered after discontinuation of vecuronium. CONCLUSION Continuous NMB produces small changes on BIS values that are not clinically significant and therefore does not interfere with BIS consciousness monitoring in critically ill children.

Abstract
BACKGROUND We aimed to examine whether using a high fraction of inspired oxygen (FIO2) in the context of an individualised intra- and postoperative open-lung ventilation approach could decrease surgical site infection (SSI) in patients scheduled for abdominal surgery. METHODS We performed a multicentre, randomised controlled clinical trial in a network of 21 university hospitals from June 6, 2017 to July 19, 2018. Patients undergoing abdominal surgery were randomly assigned to receive a high (0.80) or conventional (0.3) FIO2 during the intraoperative period and during the first 3 postoperative hours. All patients were mechanically ventilated with an open-lung strategy, which included recruitment manoeuvres and individualised positive end-expiratory pressure for the best respiratory-system compliance, and individualised continuous postoperative airway pressure for adequate peripheral oxyhaemoglobin saturation. The primary outcome was the prevalence of SSI within the first 7 postoperative days. The secondary outcomes were composites of systemic complications, length of intensive care and hospital stay, and 6-month mortality. RESULTS We enrolled 740 subjects: 371 in the high FIO2 group and 369 in the low FIO2 group. Data from 717 subjects were available for final analysis. The rate of SSI during the first postoperative week did not differ between high (8.9%) and low (9.4%) FIO2 groups (relative risk [RR]: 0.94; 95% confidence interval [CI]: 0.59-1.50; P=0.90]). Secondary outcomes, such as atelectasis (7.7% vs 9.8%; RR: 0.77; 95% CI: 0.48-1.25; P=0.38) and myocardial ischaemia (0.6% [n=2] vs 0% [n=0]; P=0.47) did not differ between groups. CONCLUSIONS An oxygenation strategy using high FIO2 compared with conventional FIO2 did not reduce postoperative SSIs in abdominal surgery. No differences in secondary outcomes or adverse events were found. CLINICAL TRIAL REGISTRATION NCT02776046.

Abstract
Nonsteroidal anti-inflammatory drugs (NSAIDs) are widely used throughout the world. They are frequently involved in hypersensitivity reactions, which range from local or mild reactions to systemic and severe reactions. Consequently, it is necessary to perform an exhaustive study of patients in order to make an accurate diagnosis, search for safe procedures in the case of severe reactions, and identify alternative treatment options. Various guidelines and protocols address the management of hypersensitivity to NSAIDs, although these vary widely from country to country. The Committees of Asthma, Rhinoconjunctivitis, and Drug Allergy of the Spanish Society of Allergy and Clinical Immunology (SEAIC) propose the present position statement on available options for provocation testing with aspirin/NSAIDs. This document is the fruit of an exhaustive review of current evidence and is based on recent publications addressing the diagnosis of patients with hypersensitivity to NSAIDs and on a consensus-oriented discussion among a group of experts from the SEAIC. The main objective was to draft an easy-toread, practical guideline for health care professionals in specialist areas who assess and manage patients with suspected hypersensitivity to NSAIDs. Furthermore, indications, contraindications, and procedures for oral, bronchial, and nasal provocation tests with aspirin/NSAIDs have been updated.

Abstract
BACKGROUND Continuous renal replacement therapy (CRRT) is the treatment of choice for critically ill children with acute kidney injury. Hypotension after starting CRRT is frequent but very few studies have analyzed its incidence and clinical relevance. METHODS A prospective, observational study was performed including critically ill children treated with CRRT between 2010 and 2014. Hemodynamic data and connection characteristics were collected before, during, and 60 min after CRRT circuit connection. Hypotension with the connection was defined as a decrease in > 20% of the mean arterial pressure from baseline or when intravenous fluid resuscitation or an increase in vasopressors was required. RESULTS One hundred sixty-one connections in 36 children (median age 18.8 months) were analyzed. Twenty-eight patients (77.8%) were in the postoperative period of cardiac surgery, 94% had mechanical ventilation, and 86.1% had vasopressors. The heparinized circuit priming solution was discarded in 8.7% and infused to the patient in 18% of the connections. The circuit was re-primed in the remaining 73.3% using albumin (79.3%), red blood cells (4.5%), or another crystalloid solution without heparin (16.2%). Hypotension occurred in 49.7% of the connections a median of 5 min after the beginning of the therapy. Fluid resuscitation was required in 38.5% and the dose of vasopressors was increased in 12.4% of the connections. There was no relationship between hypotension and age or weight. Re-priming the circuit with albumin reduced the incidence of hypotension from 71.4 to 44.6% (p = 0.004). CONCLUSIONS Hypotension after the connection to CRRT is very frequent in critically ill children. Re-priming the circuit with albumin could improve hemodynamics during connection.

Microcirculatory Differences in Children With Congenital Heart Disease According to Cyanosis and Age. Front Pediatr 2019; 7:264.

Abstract
Background: Congenital heart disease (CHD) is one of the main causes of morbidity and mortality in children. Microcirculatory changes in CHD patients have previously been investigated using a variety of techniques. Handheld videomicroscopy enables non-invasive direct visualization of the microcirculatory bed. The aim of our study was to determine if there are microcirculatory differences among CHD patients based on age and the presence of cyanosis. Methods: A prospective observational study was carried out. Patients with CHD undergoing corrective surgery were evaluated after anesthetic induction prior to surgery. Microcirculation was evaluated using sidestream dark field (SDF) imaging. Hemodynamics and respiratory, biochemical, and tissue perfusion parameters were analyzed. Results: A total of 30 patients were included, of whom 14 were classified as cyanotic and 16 as non-cyanotic. Cyanotic patients had a higher total vessel density (TVD) (p = 0.016), small vessel density (p = 0.004), and perfused small vessel density (p = 0.013), while their microvascular flow index (MFI) was lower (p = 0.013). After adjustment for age and PaO2, cyanotic patients showed increased TVD (p = 0.023), and small vessel density (p = 0.025) compared to non-cyanotic patients but there were no differences on the MFI. Age was directly correlated with total MFI (spearman's rho = 0.499, p = 0.005) and small vessel MFI (spearman's rho = 0.420, p = 0.021). After adjustment for the type of CHD (cyanotic vs. non-cyanotic) patients with MFI and small MFI vessels <3 were younger than those with values ≥3 (p = 0.033 and p = 0.037). Conclusions: SDF-based evaluation of microcirculation in CHD patients showed that patients with cyanotic defects had higher vascular density, as compared to patients with non-cyanotic defects. Younger patients were more likely to have a low MFI regardless of their type of CHD.

Abstract
Felid semen has historically been frozen using an egg yolk-based cryopreservation medium (TEY). However, the use of egg introduces several potential concerns, such as variability in composition, microbial contamination, and regulatory issues. Our recent research has focused on developing an animal protein-free medium containing soy lecithin (SOY). Our studies revealed that SOY was superior to TEY for freezing domestic cat sperm and provided similar results for freezing ocelot, Pallas’ cat, and fishing cat sperm. The objective of this study was to compare SOY to the standard TEY for sperm cryopreservation in 2 wild cat species: the black-footed cat and sand cat. Semen was collected from adult male cats (n=6/species) via electroejaculation, split into 2 aliquots, centrifuged, resuspended in either SOY or TEY, slow-cooled, and frozen in straws over nitrogen vapor. Sperm motility [percent progressively motile (PPM); rate of progressive motility on 0-5 scale (RPM)] was evaluated at 0, 1, 3, 6, and 24h post-thaw and acrosome status (AC) was assessed at 0 and 6h post-thaw. Heterologous IVF was performed using oocytes collected laparoscopically from gonadotropin-treated domestic cats. At 48h post-insemination, Hoechst33342 staining was used to determine oocyte stage, number of blastomeres, and number of accessory sperm (AS) bound to the zona pellucida of embryos and mature oocytes. Percent progressively motile, RPM, and AC were analysed with repeated-measures ANOVA; embryo cleavage, blastomere number, and AS number were analysed with one-way ANOVA. All data are reported as least squares means±average standard error. In the black-footed cat, PPM, RPM, and AC of SOY-treated sperm (32.5±4.0% motile, 2.8±0.2 RPM, 41.8±4.1% intact; 0h) did not differ from TEY-treated sperm (44.2±4.0% motile, 2.8±0.2 RPM, 46.8±4.1% intact; 0h) at any post-thaw time point (P > 0.05). Similarly, in the sand cat, post-thaw PPM, RPM, and AC of SOY-treated sperm (36.7±5.2% motile, 2.6±0.2 progression, 53.3±5.8% intact; 0h) did not differ from TEY-treated sperm (45.8±5.2% motile, 2.8±0.2 RPM, 51.0±5.8% intact; 0h) at any time point (P > 0.05). In black-footed cats, neither embryo cleavage (34.1±10.9% SOY; 58.5±10.9% TEY), blastomere number (7.8±0.8 SOY; 6.3±0.8 TEY), nor AS (3.5±0.8 SOY; 1.7±0.8 TEY) differed between treatments (P > 0.05). Sand cat results were similar, with no difference between SOY and TEY for cleavage (44.7±10.8% SOY; 40.6±10.8% TEY) or blastomere number (7.4±2.0 SOY; 6.7±2.0 TEY) (P > 0.05), but AS was higher in SOY-treated sperm (4.3±0.2 SOY; 3.5±0.2 TEY, P=0.0183). These data collectively demonstrate that our SOY medium was an effective substitute to TEY for sperm cryopreservation in the black-footed cat and sand cat. The replacement of an egg yolk-based cryomedium with a chemically defined, animal protein-free alternative represents a significant advance in quality control and biosecurity for felid semen banking and should augment the use of assisted reproduction for population management of imperiled cats.
