0 %; p = 0.014) for HF management post-discharge when compared to controls. There was a lower heart transplant-free survival at 7 months in patients with dysfunction compared to controls (50.6 vs. 90.9 %; p = 0.040). Trolox ECMO support (p = 0.001) and duration of inotropic support (p = 0.04) were significantly associated with death or transplantation before stage II palliation. Patients with ventricular dysfunction received more HF management and related admissions. Longer inotropic support should prompt discussion regarding alternative treatment strategies given its association with death or transplant.Echocardiography is the mainstay of screening and disease surveillance in isolated left ventricular non-compaction (iLVNC). The aim of our study is to determine the early regional and global myocardial functional changes and whether the myocardial changes that cannot be detected by conventional echocardiography could be detected by tissue Doppler imaging (TDI) or two-dimensional speckle-tracking echocardiography (STE) in iLVNC cases without symptoms. Longitudinal and circumferential strain (S) and strain rates (SR) as determined by STE in 20 children aged 12.1 ± 3.3 years was compared with those in 20 controls. All children underwent echocardiographic assessment using two-dimensional, tissue Doppler and speckle-tracking echocardiography. link2 iLVNC patients who had normal systolic function by ejection and shortening fractions were included in this study. According to the TDI in all three segments [the non-compacted (NC), neighboring NC (NNC) and compacted (C) segments], isovolumic contraction time, isovolumic relaxation time and myocardial performance index values were significantly higher, while ejection time were significantly lower in the iLVNC group. According to STE in two segments (NC and NNC-segments) longitudinal S and SR values and also circumferential S and SR values were significantly lower in the iLVNC group compared with the control group; whereas, in the global measurements both longitudinal and circumferential S and SR values in all three segments were significantly lower in the iLVNC group compared with the control group. We believe that TDI and STE that evaluates myocardial deformation can be used for the detection of early myocardial dysfunction in the iLVNC patients who are subclinical and whose left ventricular functions were detected as normal by conventional methods with normal ejection and shortening fractions.The aim of the study was to examine the effects of exercise training on aerobic capacity and pulmonary function in children and adolescents after congenital heart disease surgery. We searched MEDLINE, Cochrane Controlled Trials Register, EMBASE, (from the earliest date available to January 2015) for controlled trials that evaluated the effects of exercise training on aerobic capacity and pulmonary function (forced expiratory volume in 1 s and forced vital capacity) in children and adolescents after congenital heart disease surgery. Weighted mean differences and 95 % confidence intervals (CIs) were calculated,, and heterogeneity was assessed using the I (2) test. Eight trials (n = 292) met the study criteria. The results suggested that exercise training compared with control had a positive impact on peak VO2. Exercise training resulted in improvement in peak VO2 weighted mean difference (3.68 mL kg(-1) min(-1), 95 % CI 1.58-5.78). link3 The improvement in forced expiratory volume in 1 s and forced vital capacity after exercise training was not significant. Exercise training may improve peak VO2 in children and adolescents after congenital heart disease surgery and should be considered for inclusion in cardiac rehabilitation. Further larger randomized controlled trials are urgently needed to investigate different types of exercise and its effects on the quality of life.The syntheses of large peptides and of those containing non-natural amino acids can be facilitated by the application of convergent approaches, dissecting the native sequence into segments connected through a ligation reaction. We describe an improvement of the ligation protocol used to prepare peptides and proteins without cysteine residues at the ligation junction. We have found that the addition of HOBt to the ligation, improves the conversion of the ligation reaction without affecting the epimerization rate or chemoselectivity, and it can be efficiently used with peptides containing phosphorylated amino acids.
To evaluate imaging changes occurring in a rat model of elastase-induced abdominal aortic aneurysm (AAA), with emphasis on the intraluminal thrombus (ILT) occurrence.
The post-induction growth of the AAA diameter was characterized using ultrasound in 22 rats. ILT was reported on 13 rats that underwent 14 magnetic resonance imaging (MRI) 2-18 days post-surgery, and on 10 rats that underwent 18 fluoro-deoxyglucose (FDG) positron emission tomography (PET)/microcomputed tomography examinations 2-27 days post-surgery. Logistic regressions were used to establish the evolution with time of AAA length, diameter, ILT thickness, volume, stratification, MRI and FDG PET signalling properties, and histological assessment of inflammatory infiltrates.
All of the following significantly increased with time post-induction (p < 0.001) AAA length, AAA diameter, ILT maximal thickness, ILT volume, ILT iron content and related MRI signalling changes, quantitative uptake on FDG PET, and the magnitude of inflammatory infiltrates on histology. However, the aneurysm growth peak followed occurrence of ILT approximately 6 days after elastase infusion.
Our model emphasizes that occurrence of ILT precedes AAA peak growth. Aneurysm growth is associated with increasing levels of iron, signalling properties changes in both MRI and FDG PET, relating to its biological activities.
• ILT occurrence in AAA is associated with increasing FDG uptake and growth. • MRI signalling changes in ILT reflect activities such as haemorrhage and RBC trapping. • Monitoring ILT activities using MRI may require no exogenous contrast agent.

To evaluate the recommendations for multiparametric prostate MRI (mp-MRI) interpretation introduced in the recently updated Prostate Imaging Reporting and Data System version 2 (PI-RADSv2), and investigate the impact of pathologic tumour volume on prostate cancer (PCa) detectability on mpMRI.
This was an institutional review board (IRB)-approved, retrospective study of 150 PCa patients who underwent mp-MRI before prostatectomy; 169 tumours ≥0.5-mL (any Gleason Score [GS]) and 37 tumours <0.5-mL (GS ≥4+3) identified on whole-mount pathology maps were located on mp-MRI consisting of T2-weighted imaging (T2WI), diffusion-weighted (DW)-MRI, and dynamic contrast-enhanced (DCE)-MRI. Corresponding PI-RADSv2 scores were assigned on each sequence and combined as recommended by PI-RADSv2. We calculated the proportion of PCa foci on whole-mount pathology correctly identified with PI-RADSv2 (dichotomized scores 1-3 vs. 4-5), stratified by pathologic tumour volume.
PI-RADSv2 allowed correct identification of 118/125 (94%; 95 %CI 90-99%) peripheral zone (PZ) and 42/44 (95%; 95 %CI 89-100%) transition zone (TZ) tumours ≥0.5mL, but only 7/27 (26%; 95 %CI 10-42%) PZ and 2/10 (20%; 95 %CI 0-52%) TZ tumours with a GS ≥4+3, but <0.5mL. DCE-MRI aided detection of 4/125 PZ tumours ≥0.5mL and 0/27 PZ tumours <0.5mL.
PI-RADSv2 correctly identified 94-95% of PCa foci ≥0.5mL, but was limited for the assessment of GS ≥4+3 tumours ≤0.5mL. DCE-MRI offered limited added value to T2WI+DW-MRI.
• PI-RADSv2 correctly identified 95% of PCa foci ≥0.5mL • PI-RADSv2 was limited for the assessment of GS ≥4+3 tumours ≤0.5mL • DCE-MRI offered limited added value to T2WI+DW-MRI.

To evaluate the impact of magnetic resonance neurography (MRN) on diagnostic thinking and therapeutic choices in patients with suspected peripheral neuropathy.
IRB approval was obtained for this HIPAA-compliant study. Questionnaires were administered to six surgeons regarding the diagnosis and treatment in 85 patients suspected of having peripheral neuropathy, before (pretest) and after (posttest) MRN. Multiple outcome measures related to diagnostic confidence and surgical decision-making were assessed.
The final cohort included 81 patients (30 men and 51 women, age 47 ± 17 years). The following changes were observed from pretest to posttest questionnaires 23% in nerve involvement (P < 0.05), 48% in degree of confidence of nerve involvement (P < 0.01), 27% in grade of injury (P < 0.05), 33% in differential diagnosis (P < 0.05), 63% in degree of confidence in need for surgery (P < 0.001), 41% in timing of surgery (P < 0.01), 30% in approach to surgery (P < 0.05), 58% in degree of confidence in approach to surgery (P < 0.001), 30% in estimated length of surgery (P < 0.05) and 27% in length of incision (P < 0.05). The dichotomous decision regarding surgical or nonsurgical treatment changed from pro to con in 17%.
MRN results significantly influenced the diagnostic thinking and therapeutic recommendations of peripheral nerve surgeons.
• In patients with peripheral neuropathy, MRN significantly impacts diagnostic thinking. • In patients with peripheral neuropathy, MRN significantly impacts therapeutic choices. • 3-T MRN should be considered in presurgical planning of patients with peripheral neuropathy.

Beyond this oversimplification, it requires several different types of ocular movements and reflexes to focus objects of interest to the fovea-the only portion of retina capable of sharp and clear vision. The different movements and reflexes that execute this task are the saccades, smooth pursuit movements, fixation, accommodation, and the optokinetic and vestibulo-ocular reflexes. Many different centres in the cerebrum, cerebellum, brainstem and thalami, control these movements via different pathways. At the outset, these mechanisms appear dauntingly complex to a radiologist. However, only a little effort could make it possible to understand these neural controls and empower the reading session. The following review on ocular movements and their neural control will enable radiologists and clinicians to correlate lesions with clinical deficits effectively without being swamped by exhaustive detail. Key Points • Knowledge of cortical and subcortical areas controlling ocular movements is important.
