Abstract
AIM The aim of the study was to investigate whether amplitude-integrated electroencephalography (aEEG) and cerebral magnetic resonance imaging (MRI) in preterm piglets would provide measures of cerebral functional, microstructural and anatomical maturation, which might reflect the signs of functional brain immaturity, documented in preterm piglets. METHODS During July-October 2013 at the NEOMUNE Centre, Copenhagen University, Denmark, 31 preterm (90% gestation) and 10 term piglets underwent aEEG on days 1, 2, 4 and 11, and MRI on day 25. Physical activity levels were recorded. RESULTS Preterm showed delayed neonatal arousal and physical activity, relative to term piglets. Preterm piglets had lower growth rates and brain volume than term piglets, but aEEG patterns were similar. MRI mean diffusivity was also similar, but fractional anisotropy (FA) was lower in preterm piglets (p < 0.001). CONCLUSION Functional brain maturation, as assessed by aEEG, was relatively advanced in preterm piglets. Conversely, the low FA in the preterm piglets suggests that the white matter microstructure remains less mature in preterm compared to term piglets at postnatal day 25. The results might be utilised to define whether and how preterm piglets may contribute to preclinical models for brain development in preterm infants.

Abstract
INTRODUCTION The diagnosis of Parkinson's disease (PD) is typically based on the presence of motor symptoms, but in the early phase of the disease, the diagnostic process can be challenging. Examination of non-motor symptoms in patients suspected of PD has gained growing attention. Olfactory tests have shown promising results as ancillary diagnostic tests. The aim of this study was to investigate how olfactory tests may be used clinically in diagnostic process in PD. METHODS A systematic search was conducted in PubMed for relevant literature on 8 March 2017. A total of 358 articles were found. Our screening process left 27 articles, which were included for further analysis. RESULTS In all, 20 of the included studies analysed the diagnostic value of olfactory testing by comparing patients with PD to healthy controls. Sensitivities varied from 61% to 95% and specificities from 66% to 99%. Ten studies used olfactory tests to distinguish between PD and diseases that mimic PD. The sensitivities varied from 62% to 92% and the specificities from 65% and 96%. CONCLUSIONS Olfactory test can be a valuable ancillary tool in the diagnostic process in PD. In a clinical setting, the identification part from Sniffin' Sticks 16 is the most usable because it may be conducted quickly and independently of disease duration and severity. Before using an olfactory test in a clinical setting, it is necessary to adjust the odours to the patient population, and to establish the optimal specificity-adjusted cut-off.

Abstract
Levodopa (l-DOPA, l-3,4-dihydroxyphenylalanine) is the most effective drug in the symptomatic treatment of Parkinson's disease (PD), but chronic use initiates a maladaptive process leading to l-DOPA-induced dyskinesia (LID). Risk factors for early onset LID include younger age, more severe disease at baseline and higher daily l-DOPA dose, but biomarkers to predict the risk of motor complications are not yet available. Here, we investigated whether CSF levels of catecholamines and its metabolites are altered in PD patients with LID [PD-LID, n = 8)] as compared to non-dyskinetic PD patients receiving l-DOPA (PD-L, n = 6), or not receiving l-DOPA (PD-N, n = 7) as well as non-PD controls (n = 16). PD patients were clinically assessed using the Unified Parkinson's Disease Rating Scale and Unified Dyskinesia Rating Scale and CSF was collected after overnight fasting and 1-2 h after oral intake of l-DOPA or other anti-Parkinson medication. CSF catecholamines and its metabolites were analyzed by HPLC with electrochemical detection. We observed (i) decreased levels of dihydroxyphenylacetic acid (DOPAC) and homovanillic acid in PD patients not receiving l-DOPA (ii) higher dopamine (DA) levels in PD-LID as compared to controls (iii) higher DA/l-DOPA and lower DOPAC/DA ratio's in PD-LID as compared to PD-L and (iv) an age-dependent increase of DA and decrease of DOPAC/DA ratio in controls. These results suggest increased DA release from non-DA cells and deficient DA re-uptake in PD-LID. Monitoring DA and DOPAC in CSF of l-DOPA-treated PD patients may help identify patients at risk of developing LID.

Abstract
Dietary n-3PUFA and gut bacteria, particularly Bacteroidetes, have been suggested to be related to adiposity. We investigated if n-3PUFA affected fat storage and cecal bacteria in piglets. Twenty-four 4-day-old piglets were allocated to formula rich in n-3PUFA (∼3E%) from fish oil (FO) or n-6PUFA from sunflower oil (SO) for 14 days. We assessed body weight, fat accumulation by dual-energy X-ray absorptiometry and microbial molecular fingerprints. Dietary PUFA-composition was reflected in higher erythrocyte n-3PUFA in the FO- than the SO-group (P<0.001). Principal component analysis revealed group differences in the overall microbiotic composition, which involved a larger Bacteroides community in the SO-group (P=0.02). There was no significant difference in body fat percentage and no relationship between fat accumulation and gut Bacteroides. Hence, this study does not support an impact of n-3PUFA or microbiota on fat accumulation during the postnatal maturation period. The impact of dietary PUFA on the gut Bacteroides warrants further investigation.
