Comparison of the Trachea in Normocephalic versus Brachycephalic Cats on the Basis of CT-Derived Measurements.

Tracheal hypoplasia is a major concern in brachycephalic dogs, but there is no consensus for the trachea in brachycephalic cats. We aimed to compare tracheal length and diameter between normo- and brachycephalic cats using computed tomography (CT) image measurements and evaluate their usefulness in tracheostomy planning. A total of 15 normocephalic and 14 brachycephalic cats were included in the study. Tracheas of normocephalic cats were significantly longer compared with brachycephalic cats. No difference was detected in tracheal diameter between normocephalic and brachycephalic cats. Both groups had a lateral diameter significantly larger than the dorsoventral diameter at the level of the cranial end of the manubrium sterni and at the level of the second rib. Normocephalic and brachycephalic cats' tracheas have the same dorsoventral flattening at the level of the cranial end of the manubrium sterni and at the level of the second rib. The location between the 4th and 5th cervical vertebrae seems the best place to perform a tracheostomy in cats due to its round shape and easily accessible anatomical location. No sign of tracheal hypoplasia in brachycephalic cats was detected. Finally, 7 mm appears to be an adequate diameter for the tracheal tubes used to perform feline tracheostomies.

Long-term outcome after decompressive hemicraniectomy for malignant middle cerebral artery infarction.

BACKGROUND: Although decompressive hemicraniectomy (DHC) is a lifesaving treatment strategy for patients with malignant middle cerebral artery infarction (mMCAi), only one in four patients achieves low to moderate post-stroke disability according to previous studies. However, the short follow-up periods in prior studies could have overestimated the poor clinical prognosis. This study therefore examined the long-term outcome after DHC for mMCAi. METHODS: We retrospectively included all patients who had undergone DHC after mMCAi at the University Hospital Graz between 2006 and 2019. Demographics, clinical data and complications were collected from electronic clinical patient records. To investigate long-term prognosis, all patients were followed up to 14 years after stroke including quality of life (QOL) assessment. Post-stroke disability was rated according to the modified Rankin Scale (mRS). RESULTS: Of 47 patients that had undergone DHC for mMCAi, follow-up data were available in 40 patients (mean age: 48 years; 40% female). Six months after the mMCAi, 14 patients had died (35%) and nine (23%) had a low to moderate post-stroke disability (mRS 0-3). Of 26 stroke survivors, half (50%) showed further mRS improvement (≥ 1 point) during the long-term follow-up period (mean follow-up time: 8 years). At last follow-up, 17 patients had achieved an mRS score of ≤ 3 (65% versus 35% after 6 months; p = 0.008) and 55% had no signs of depression and anxiety, and 50% no signs of pain or discomfort in QOL assessment. CONCLUSION: This study shows substantial long-term improvement of functional disability and reasonable QOL in mMCAi patients after DHC.

CT measurements of tracheal diameter and length in normocephalic cats.

OBJECTIVES: The aim of this study was to measure the tracheal dimensions of normocephalic cats using CT. METHODS: CT images of 15 client-owned normocephalic cats were retrospectively evaluated to measure the length of the feline trachea. Transverse and vertical inner diameters were measured in five different tracheal regions, and the cross-sectional area of the tracheal lumen was calculated for each point of measurement. Descriptive statistics were applied using a two-tailed t-test. RESULTS: The mean ± SD length of the trachea was 125.13 ± 14.41 mm. Male cats had significantly larger tracheas than female cats. The transverse diameter first increased by 0.94 mm between the most cranial point of measurement and the middle of the trachea. It then decreased by 1.38 mm between the middle of the trachea and the most caudal point of measurement. The vertical diameter decreased by 1.16 mm between the first point of measurement and the penultimate point, and then increased by 0.06 mm between the penultimate point of measurement and the end of the trachea. The two different diameters resulted in an elliptical trachea shape. CONCLUSIONS AND RELEVANCE: The feline trachea was circular only at its cranial and caudal ends, and elliptical with a dorsoventral flattening along the rest of its length. Vertical and transverse diameters varied along the entire length. Tracheal shape differences should be considered when performing permanent tracheostomy, tracheal anastomosis or stenting in cats.

Concentrations and kinetics of renal biomarkers in dogs with gastric dilatation-volvulus with and without 24-h intravenous lidocaine.

Background: Gastric dilatation volvulus (GDV) can lead to organ failure including acute kidney injury (AKI). Due to its cytoprotective, antioxidant and anti-inflammatory effects, lidocaine has a potential to prevent AKI in dogs with GDV. Design and setting: Prospective, observational cohort study in client-owned dogs with GDV. Objective: To determine concentrations of renal biomarkers for AKI in dogs with GDV with and without intravenous (IV) lidocaine therapy. Methods: Thirty-two dogs were randomized to receive either IV lidocaine (2 mg/kg, followed by a lidocaine constant rate infusion at a dose of 50 µg/kg/min over 24 h; n = 17) or no lidocaine (n = 15). Blood and urine samples were taken at admission (T 0) (only blood), during or immediately after surgery (T 1), and 24 (T 24) and 48 (T 48) h after surgery. Plasma creatinine (pCr), plasma neutrophil gelatinase-associated lipocalin (pNGAL), urinary NGAL (uNGAL), uNGAL to creatinine ratio (UNCR), and urinary gamma-glutamyl transferase to creatinine ratio (uGGT/uCr) were evaluated. Biomarker concentrations were compared between dogs with and without IV lidocaine and the course of each marker was determined in comparison to its admission value. Results: In the entire population, a significantly higher pCr at T 0 (median, 95 µmol/L, interquartile range, 82-105) compared with T 1 (69 µmol/L, 60-78), T 24 (63 µmol/L, 52-78), and T 48 (78 µmol/L, 65-87) (P < 0.001) was found. Plasma NGAL increased significantly between T 0 (5.66 ng/mL, 3.58-7.43) and T 24 (7.50 ng/mL, 4.01-11.89) (P = 0.006) and T 48 (9.86 ng/mL, 5.52-13.92) (P < 0.001), respectively. Urinary NGAL increased significantly between T 1 (0.61 ng/mL, 0.30-2.59) and T 24 (2.62 ng/mL, 1.86-10.92) (P = 0.001) and T 48 (4.79 ng/mL, 1.96-34.97 (P < 0.001), respectively. UNCR increased significantly between T 1 (0.15 µg/mmol, 0.09-0.54) and T 24 (1.14 µg/mmol, 0.41-3.58) (P = 0.0015) and T 48 (1.34 µg/mmol, 0.30-7.42) (P < 0.001), respectively. Concentrations of uGGT/uCr increased significantly from T 0 highest at T 24 (6.20 U/mmol, 3.90-9.90) and significantly decreased at T 48 (3.76 U/mmol, 2.84-6.22) (P < 0.001). No significant differences in any renal biomarker concentration were found between dogs with and without IV lidocaine therapy. Conclusion and clinical relevance: Plasma NGAL, uNGAL and UNCR remained increased up to 48 h post-surgery. No evidence of lidocaine-associated renoprotection was found.

Inflammatory biomarker concentrations in dogs with gastric dilatation volvulus with and without 24-h intravenous lidocaine.

Background: Canine gastric dilatation volvulus (GDV) is characterized by tissue ischemia, reperfusion, and systemic inflammation. Evidence exists that lidocaine exerts anti-inflammatory properties and potentially improves outcome. Design and setting: Prospective, randomized observational cohort study in client-owned dogs with GDV. Objective: The primary objective of the study was the determination of pro- and anti-inflammatory biomarker concentrations in dogs with GDV with and without intravenous (IV) lidocaine therapy. The second objective was the evaluation of side effects of lidocaine. Methods: Of 35 dogs included in the study, 20 dogs were assigned to receive lidocaine (LIDO) (2 mg/kg initially, followed by a continuous infusion at a rate of 50 µg/kg/min over 24 h) and 15 dogs not to receive lidocaine (NO-LIDO). Plasma concentrations of cytokines interleukin (IL)-6, IL-7, IL-8, IL-10, IL-15, IL-18, interferon gamma, keratinocyte chemotactic-like, monocyte chemotactic protein, and C-reactive protein (CRP) were measured at admission (prior any therapeutic intervention, T0), immediately after surgery (T1), at 24 h (T24), and at 48 h (T48) post-surgery. Results: No significant differences in concentrations of any cytokines were found between the LIDO- and the NO-LIDO group. Significant lower CRP concentrations (median [range]) were found in dogs with lidocaine compared to dogs without at T24 (97.5 pg/mL [46.3-161.7] vs. 127.9 pg/mL [26.9-182.0]; p = 0.046) and T48 (73.7 pg/mL [18.4-169.4] vs. 116.3 pg/mL [71.4-176.8]; p = 0.002). Dogs receiving lidocaine exhibited significantly impaired mentation, a prolonged period of anorexia, and longer hospitalization compared to dogs without lidocaine. Conclusion: Lidocaine administration had no impact on the plasma levels of cytokines during the 48-h study period, but significantly lower CRP concentrations were found at T24 and T48. Lidocaine's potential side effects require careful decision making regarding its use.

Paediatric and adult congenital cardiology education and training in Europe.

BACKGROUND: Limited data exist on training of European paediatric and adult congenital cardiologists. METHODS: A structured and approved questionnaire was circulated to national delegates of Association for European Paediatric and Congenital Cardiology in 33 European countries. RESULTS: Delegates from 30 countries (91%) responded. Paediatric cardiology was not recognised as a distinct speciality by the respective ministry of Health in seven countries (23%). Twenty countries (67%) have formally accredited paediatric cardiology training programmes, seven (23%) have substantial informal (not accredited or certified) training, and three (10%) have very limited or no programme. Twenty-two countries have a curriculum. Twelve countries have a national training director. There was one paediatric cardiology centre per 2.66 million population (range 0.87-9.64 million), one cardiac surgical centre per 4.73 million population (range 1.63-10.72 million), and one training centre per 4.29 million population (range 1.63-10.72 million population). The median number of paediatric cardiology fellows per training programme was 4 (range 1-17), and duration of training was 3 years (range 2-5 years). An exit examination in paediatric cardiology was conducted in 16 countries (53%) and certification provided by 20 countries (67%). Paediatric cardiologist number is affected by gross domestic product (R2 = 0.41). CONCLUSION: Training varies markedly across European countries. Although formal fellowship programmes exist in many countries, several countries have informal training or no training. Only a minority of countries provide both exit examination and certification. Harmonisation of training and standardisation of exit examination and certification could reduce variation in training thereby promoting high-quality care by European congenital cardiologists.

Antiarrhythmic Medication in Neonates and Infants with Supraventricular Tachycardia.

Supraventricular tachycardia (SVT) is the most common arrhythmia in neonates and infants, and pharmacological therapy is recommended to prevent recurrent episodes. This retrospective study aims to describe and analyze the practice patterns, effectiveness, and outcome of drug therapy for SVT in patients within the first year of life. Among the 67 patients analyzed, 48 presented with atrioventricular re-entrant tachycardia, 18 with focal atrial, and one with atrioventricular nodal re-entrant. Fetal tachycardia was reported in 27%. Antiarrhythmic treatment consisted of beta-receptor blocking agents in 42 patients, propafenone in 20, amiodarone in 20, and digoxin in 5. Arrhythmia control was achieved with single drug therapy in 70% of the patients, 21% needed dual therapy, and 6% triple. Propafenone was discontinued in 7 infants due to widening of the QRS complex. After 12 months (6-60), 75% of surviving patients were tachycardia-free and discontinued prophylactic treatment. Patients with fetal tachycardia had a significantly higher risk of persistent tachycardia (p: 0.007). Prophylactic antiarrhythmic medication for SVT in infancy is safe and well tolerated. Arrhythmia control is often achieved with single medication, and after cessation, most patients are free of arrhythmias. Infants with SVT and a history of fetal tachycardia are more prone to suffer from persistent SVT and relapses after cessation of prophylactic antiarrhythmic medication than infants with the first episode of SVT after birth.

Preservation of nasal turbinates in endoscopic, anterior skull base surgery-yes, we can!

OBJECTIVE: To evaluate the frequency, type and indications of nasal turbinate (NT) resection during endoscopic, anterior skull base surgery and to analyze factors that may have an impact on the need of NT removal. METHODS: In this retrospective cohort study, 306 subjects (150 males and 156 females, mean age 55.4 ± 15.3 years) who underwent multidisciplinary, transnasal, endoscopic tumor surgery of the anterior skull base using 4-handed techniques between 2011 and 2019 at the Department of Otorhinolaryngology, Medical University of Graz, were included. RESULTS: In the majority of interventions (n = 281/306; 91.8%), all NT were preserved. Significant factors influencing the need of NT resections turned out to be type of endoscopic approach (p < 0.001; V = 0.304), sagittal (p = 0.003; d = 0.481) and transversal (p = 0.017; d = 0.533) tumor diameter, tumor type (p < 0.001; V = 0.355) and tumor location (p < 0.001; V = 0.324). CONCLUSIONS: NT can be preserved in the majority of patients undergoing tumor resection in anterior, transnasal, skullbase surgery and routine resection of NT should be avoided. Variables that have an impact on the need of NT resections are types of endoscopic approaches, sagittal and transversal tumor extension and tumor type. These factors should be considered in planning of surgery and preoperative information of patients.

A postresection perfusion deficit in the right colon is an independent predictor of perioperative outcome after major hepatectomy.

BACKGROUND: There is a strong interaction between hepatic hemodynamics and perfusion in the splanchnic system. However, little is known about differences in perfusion in different splanchnic compartments and their changes after hepatectomy. METHODS: Perfusion in various splanchnic compartments (ie, stomach, small intestine, right and left colon, liver) was assessed pre- and post-hepatectomy by intraoperative laser Doppler flowmetry. Differences of splanchnic perfusion between compartments were evaluated by ANOVA, and risk factors of postoperative complications (graded by the comprehensive complication index [CCI]) were analyzed by univariate and multivariate analyses. A prediction model of postoperative complications was developed. RESULTS: A total of 50 and 29 patients with major and minor hepatectomy were enrolled. Splanchnic perfusion at baseline varied significantly across different splanchnic compartments with highest values in the small bowel and right colon (P < .001). Major hepatectomy induced a significant perfusion decrease in the stomach (P = .006), right colon (P < .001) and small bowel (P = .035). A postresection perfusion deficit in the right colon with values below 254 perfusion units (PU) was identified as an independent predictor of clinically relevant complications after major hepatectomy (concordance index: 0.79, 95% CI 0.66-0.87, P = .002). Bootstrap validation confirmed internal validity and excellent calibration. CONCLUSIONS: Major hepatectomy causes significant reduction of splanchnic perfusion. An intraoperative posthepatectomy microcirculatory perfusion deficit of the right colon is a strong and independent predictor of clinically relevant postoperative complications after major hepatectomy.

Kinetics of Plasma Cytokines, Angiopoietin-2, and C-Reactive Protein in Dogs With Gastric Dilatation Volvulus.

Background: The degree of systemic inflammation, reperfusion injury and endothelial activation are potentially important determinants of clinical outcomes in dogs with gastric dilatation volvulus (GDV). Objective: To evaluate plasma concentrations and kinetics of inflammatory markers in dogs with GDV over a time frame of 48 h, and to compare to healthy dogs. Design and Setting: Prospective, observational cohort study in client-owned dogs with GDV. Materials and Methods: Fifteen dogs with GDV and 9 healthy control dogs were enrolled. Plasma concentrations of interleukin (IL)-6, IL-7, IL-8, IL-10, IL-15, IL-18, interferon gamma (IFN-γ), keratinocyte chemotactic-like, monocyte chemotactic protein (MCP)-1, Angiopoietin (Ang)-2, and C-reactive protein (CRP) were measured at admission (prior any therapeutic intervention, (T0), immediately after surgery (T1), 24 ± 4 h (T24), and 48 ± 4 h (T48) post-surgery. Cytokines were measured using multiplex magnetic bead assay. Plasma Ang-2 was measured with a commercial human ELISA test kit validated for dogs. Results: Dogs with GDV had significantly higher plasma concentrations of IFN-γ and IL-10 compared to healthy control dogs at all time points. Concentrations of IL-6 were significantly higher at T1 and T24, concentrations of MCP-1 at T24, and concentrations of CRP at T24 and T48. A significant increase between T0 and T1 was found for IL-6, IL-10, and CRP, between T1 and T24 for IL-8, IFN-γ, MCP-1, and CRP, and between T24 and T48 for IL-15, Ang-2, and CRP. A significant decrease between T0 and T1 was found for IL-7, IL-8, IL-15, IL-18, and Ang-2; between T1 and T24 for IL-6 and KC-like; and between T24 and T48 for IL-6. Conclusion: In GDV dogs, a mild pro-inflammatory reaction was present at admission, which peaked immediately after and up to 24 h post-surgery, mainly represented by IL-6, IFN-γ, MCP-1, and CRP, and which decreased at T48. In addition, the anti-inflammatory IL-10 was increased in GDV dogs at all time points.

Spinal Arachnoiditis Ossificans: A Case-Based Update.

Arachnoiditis ossificans is a rare disease, characterized by intradural ossifications, representing the end stage of chronic adhesive arachnoiditis. We describe the case of a 55-year-old patient who developed symptoms of a cauda equina syndrome after an open microdiscectomy at the L5 to S1 segment. A subsequent exploratory surgery revealed an intradural concentric bony structure with partly incorporated and partly adherent nerve roots. A partial removal of the intradural calcifications was performed. Postoperatively, the patient showed neurological improvement. The removed intradural calcifications were submitted for histological analysis and proved to be normal bone tissue, notably containing yellow bone marrow. To our knowledge, the presence of yellow bone marrow within bony cavities of arachnoiditis ossificans has not previously been reported.

Features of schizophrenia following premorbid eating disorders.

OBJECTIVE: Eating disorders (ED) and schizophrenia are frequently comorbid and schizophrenia shares genetic susceptibility with anorexia. Many factors associated with schizophrenia can disrupt eating, but ED can present years before schizophrenia. If premorbid ED distinguishes a particular subtype of schizophrenia, then phenotypic features may differ between schizophrenia cases with and without premorbid ED. METHOD: This secondary analysis used data from an inpatient schizophrenia research study that comprehensively assessed life course psychiatric disorders (DIGS interview), intelligence (WAIS), global assessments of function (GAF) and assessed symptoms during medication-free and fixed dose neuroleptic phases (PANSS). RESULTS: Premorbid ED was identified in 27 of the 288 schizophrenia cases (9.4%). This group had more females than the group without premorbid ED (74.1% vs. 30%); premorbid ED was 5-fold more common in female than male cases (χ2 (17.9, P < .0001). Only the premorbid ED group had gustatory hallucinations. They also demonstrated significantly more severe psychotic and disorganization symptoms during medication-free and fixed dose treatment phases, despite similar negative symptoms and GAF scores, as other cases. The premorbid ED group had significantly better cognition overall, but relatively lower nonverbal than verbal intelligence. DISCUSSION: Premorbid ED may define a specific subtype of schizophrenia that is common in females. Their more severe psychotic symptoms and better IQ, despite similarly impaired function and negative symptoms as other cases, suggests a distinct pathophysiology. Premorbid ED should be considered in evaluating risk states for schizophrenia, and as a relevant phenotype for treatment resistant schizophrenia.

Extracorporeal membrane oxygenation support in pediatrics.

Extracorporeal membrane oxygenation (ECMO) is a general term that describes the short- or long-term support of the heart and/or lungs in neonates, children and adults. Due to favorable results and a steady decline in absolute contraindications, its use is increasing worldwide. Indications in children differ from those in adults. The ECMO circuit as well as cannulation strategies also are individualized, considering their implications in children. The aim of this article is to review the clinical indications, different circuits, and cannulation strategies for ECMO. We also present our institutional experience with 92 pediatric ECMO patients (34 neonates, 58 pediatric) with the majority (80%) of veno-arterial placements between 2014 until 2018. We further to also highlight ECMO use in the setting of cardiac arrest [extracorporeal cardiopulmonary resuscitation (CPR) or eCPR].

Prenatal Diagnosis of Single Ventricle Physiology Impacts on Cardiac Morbidity and Mortality.

We sought to evaluate the impact of prenatal diagnosis on morbidity and mortality in single ventricle (SV) lesions. All consecutive patients with pre- or postnatally diagnosed SV physiology admitted to our centre between January 2001 and June 2013 were reviewed. Primary endpoints included survival until 30 days after bidirectional cavopulmonary connection (BCPC) without transplant or BCPC takedown. Prenatal diagnosis was performed in 160 of 259 cases (62%). After excluding all cases with termination of pregnancy, intrauterine demise or treated with comfort care, a total of 180 neonates were admitted to our centre for treatment, including 87 with a prenatal and 93 with a postnatal diagnosis. Both groups showed similar distribution regarding diagnosis, dominant ventricle and risk factors such as restrictive foramen or some form of atrial isomerism. A larger proportion of postnatally diagnosed children presented at admission with elevated lactate > 10 mmol/l (p = 0.02), a higher dose of prostaglandin (p = 0.0013) and need for mechanical ventilation (p < 0.0001). Critical lesions such as hypoplastic left heart syndrome were an important determinant for morbidity and mortality. Thirty-days survival after BCPC was better in patients with prenatal diagnosis (p = 0.025). Prenatal diagnosis is associated with higher survival in neonates with SV physiology.

Prevention of Low Cardiac Output Syndrome After Pediatric Cardiac Surgery: A Double-Blind Randomized Clinical Pilot Study Comparing Dobutamine and Milrinone.

OBJECTIVES: Dobutamine and milrinone are commonly used after open-heart surgery to prevent or treat low cardiac output syndrome. We sought to compare efficacy and safety of these drugs in pediatric patients. DESIGN: Prospective, single-center, double-blinded, randomized clinical pilot study. SETTING: Tertiary-care university children's hospital postoperative pediatric cardiac ICU. PATIENTS: After written consent, 50 consecutive patients (age, 0.2-14.2 yr; median, 1.2 yr) undergoing open-heart surgery for congenital malformations were included. INTERVENTIONS: After cardiopulmonary bypass, a continuous infusion of either dobutamine or milrinone was administered for the first 36 postoperative hours. Maximum dose: dobutamine 6 µg/kg/min, milrinone 0.75 µg/kg/min. MEASUREMENTS AND MAIN RESULTS: There were no significant differences in demographic data, complexity of surgery, and intraoperative characteristics between the two study groups (dobutamine vs milrinone). Efficacy was defined as need for additional vasoactive support, which did not differ between groups (dobutamine 61% vs milrinone 67%; p = 0.71). Sodium nitroprusside was used more often in the dobutamine group (42% vs 13%; p = 0.019). Systolic blood pressure showed a trend toward higher values in the dobutamine group, whereas both drugs increased heart rate early postoperatively. Echocardiography demonstrated a consistently good cardiac function in both groups. Central venous oxygen saturation, serum lactate levels, urine output, time to chest tube removal, length of mechanical ventilation, ICU, and hospital stay were similar in both groups. Both drugs were well tolerated, no serious adverse events occurred. CONCLUSIONS: Dobutamine and milrinone are safe, well tolerated, and equally effective in prevention of low cardiac output syndrome after pediatric cardiac surgery. The hemodynamic response of the two drugs is comparable. In uncomplicated cases, a trend toward the more cost-saving dobutamine might be anticipated; however, milrinone demonstrated a trend toward higher efficacy in afterload reduction.

Prognostic value of troponin in infants with hypoplastic left heart syndrome between Stage I and II of palliation.

BACKGROUND: The period between stage I and II procedure for treatment of hypoplastic left heart syndrome (HLHS) bears high mortality and morbidity. METHODS: We sought to analyze the prognostic value of Troponin T/I (Trop), a well-recognized marker for myocardial damage and heart failure, for predicting outcome in a retrospective analysis of 70 infants with HLHS at our institution between March 2001 and October 2014. RESULTS: Stage I procedure consisted of Norwood I operation in 35 (50%) and Hybrid-approach in 22 (31%) patients. Palliative care was chosen for 13 (19%) patients. Trop values were collected from clinical charts and were analyzed in relation to the overall outcome. Trop was significantly higher after Norwood I operation in comparison to Hybrid-approach (median 7.1 µg/l (0.7-20.9), vs 1.2 µg/l (0.3-17.9), P < 0.001). Overall mortality of treated patients was 39% (22 patients). Survival was 54% (19 patients) after Norwood and 73% (16 patients) after Hybrid-approach. Independently from the procedure used, maximal Trop and initial lactate values were significantly higher in non-survivors than in survivors, with median Trop of 9 µg/l (0.6-18.8) vs. 3.4 µg/l (0.4-20.9), P 0.007, and median lactate of 3.7 mmol/L (1.6-25) vs. 2.9 mmol/L (0.3-14.6), p 0.03. Reinterventions were required in 17 (30%) patients, 4 (11%) after Norwood and 13 (59%) after Hybrid procedure. No correlation was found between the need for reintervention and Trop levels in the interstage period. CONCLUSIONS: Patients with HLHS have significantly higher Trop levels after Norwood procedure than after Hybrid-approach. Maximal Trop values were related to mortality, but did not correlate with the need for reinterventions.

Cognitive reappraisal and acceptance: Effects on emotion, physiology, and perceived cognitive costs.

Two emotion regulation strategies-cognitive reappraisal and acceptance-are both associated with beneficial psychological health outcomes over time. However, it remains unclear whether these 2 strategies are associated with differential consequences for emotion, physiology, or perceived cognitive costs in the short-term. The present study used a within-subjects design to examine the effects of reappraisal (reframing one's thoughts) and acceptance (accepting feelings without trying to control or judge them) on the subjective experience of negative emotions, positive emotions, and physiological responses during and following recovery from sad film clips shown in the laboratory. Participants also reported on perceived regulatory effort, difficulty, and success after deploying each emotion regulation strategy. In 2 samples of participants (N = 142), reappraisal (vs. acceptance) was associated with larger decreases in negative and larger increases in positive emotions, both during the film clips and recovery period. However, acceptance was perceived as less difficult to deploy than reappraisal, and was associated with a smaller dampening of skin conductance level (indicating more successful regulation) during the film clips in 1 sample. These results suggest that reappraisal and acceptance may exert differential short-term effects: Whereas reappraisal is more effective for changing subjective experiences in the short term, acceptance may be less difficult to deploy and be more effective at changing one's physiological response. Thus, these 2 strategies may both be considered "effective" for different reasons. (PsycINFO Database Record

Cardiac transplantation in a neonate-First case in Switzerland and European overview.

Twenty-four percent of pediatric heart transplantations (pHTx) are carried out in infants. Neonatal heart transplantation is both rarely performed and challenging. We report on a newborn baby girl suffering from cardiac failure due to a huge tumor (24×52 mm) within the free wall of the left ventricle (LV) and subtotal obstruction of the main left bronchus. Following a surgical tumor resection, a Berlin Heart EXCOR left ventricular assist device was implanted as the bridge to the transplantation. In spite of an organ donor/recipient mismatch of >200%, both heart transplantation and the postoperative course were successful. In addition to this case report, the authors also present data from a survey on performed infant and neonatal transplantations in Western Europe. As neonatal heart transplantation is a rare event in Europe, the authors think it is of crucial importance to share this limited experience. We discuss an alternative strategy-namely, palliative surgical correction using the Fontan pathway. The challenges of donor/recipient weight mismatch and the possibilities of overcoming infant donor organ shortage as a postoperative immunosuppressive regimen are discussed as well.
