Abstract
Climate change can significantly influence terrestrial water changes around the world particularly in places that have been proven to be more vulnerable such as Bangladesh. In the past few decades, climate impacts, together with those of excessive human water use have changed the country's water availability structure. In this study, we use multi-mission remotely sensed measurements along with a hydrological model to separately analyze groundwater and soil moisture variations for the period 2003-2013, and their interactions with rainfall in Bangladesh. To improve the model's estimates of water storages, terrestrial water storage (TWS) data obtained from the Gravity Recovery And Climate Experiment (GRACE) satellite mission are assimilated into the World-Wide Water Resources Assessment (W3RA) model using the ensemble-based sequential technique of the Square Root Analysis (SQRA) filter. We investigate the capability of the data assimilation approach to use a non-regional hydrological model for a regional case study. Based on these estimates, we investigate relationships between the model derived sub-surface water storage changes and remotely sensed precipitations, as well as altimetry-derived river level variations in Bangladesh by applying the empirical mode decomposition (EMD) method. A larger correlation is found between river level heights and rainfalls (78% on average) in comparison to groundwater storage variations and rainfalls (57% on average). The results indicate a significant decline in groundwater storage (∼32% reduction) for Bangladesh between 2003 and 2013, which is equivalent to an average rate of 8.73 ± 2.45mm/year.

Abstract
Questionnaire studies suggest that stroke patients experience sustained problems with sleep and daytime sleepiness, but physiological sleep studies focussing specifically on the chronic phase of stroke are lacking. Here we report for the first time physiological data of sleep and daytime sleepiness obtained through the two gold-standard methods, nocturnal polysomnography and the Multiple Sleep Latency Test. Data from community-dwelling patients with chronic right-hemispheric stroke (>12 months) were compared to sex- and age-matched controls. Behavioural and physiological measures suggested that stroke patients had poorer sleep with longer sleep latencies and lower sleep efficiency. Patients further spent more time awake during the night, and showed greater high-frequency power during nonREM sleep than controls. At the same time the Multiple Sleep Latency Test revealed greater wake efficiency in patients than controls. Importantly these findings were not due to group differences in sleep disordered breathing or periodic limb movements. Post-stroke insomnia is presently not adequately addressed within the care pathway for stroke. A holistic approach to rehabilitation and care provision, that includes targeted sleep interventions, is likely to enhance long-term outcome and quality of live in those living with chronic deficits after stroke.

Abstract
Representing a phylogenetically old and very basic mechanism of inhibitory neurotransmission, glycine receptors have been implicated in the modulation of behavioral components underlying defensive responding toward threat. As one of the first findings being confirmed by genome-wide association studies for the phenotype of panic disorder and agoraphobia, allelic variation in a gene coding for the glycine receptor beta subunit (GLRB) has recently been associated with increased neural fear network activation and enhanced acoustic startle reflexes. On the basis of two independent healthy control samples, we here aimed to further explore the functional significance of the GLRB genotype (rs7688285) by employing an intermediate phenotype approach. We focused on the phenotype of defensive system reactivity across the levels of brain function, structure, and physiology. Converging evidence across both samples was found for increased neurofunctional activation in the (anterior) insular cortex in GLRB risk allele carriers and altered fear conditioning as a function of genotype. The robustness of GLRB effects is demonstrated by consistent findings across different experimental fear conditioning paradigms and recording sites. Altogether, findings provide translational evidence for glycine neurotransmission as a modulator of the brain's evolutionary old dynamic defensive system and provide further support for a strong, biologically plausible candidate intermediate phenotype of defensive reactivity. As such, glycine-dependent neurotransmission may open up new avenues for mechanistic research on the etiopathogenesis of fear and anxiety disorders.

Abstract
IntroductionDeficits in behavioral inhibition leading to impulsivity occur frequently in many otherwise different psychiatric diseases, mainly ADHD and borderline personality disorder (BPD). However, the research is complicated by using of different tests and their parameters. Further, the role of frontoparietal network in behavioral inhibition has been questioned recently.ObjectivesThe aims of our studies were:– to present the influence of differences in inhibition tasks parameters;– to describe neural correlates of behavioral inhibition in healthy people;– to compare them with BPD and ADHD patients.MethodsWe implemented two different variants of Go/NoGo Task, one designed for behavioral research and the second for neuroimaging. Thirty healthy participants (37% of women, age range 15 to 33 years) underwent behavioral and fMRI measurement. Further, groups of patients with BPD, ADHD and their healthy controls underwent the Go/NoGo Task under both fMRI and EEG.ResultsThe results show differences in behavioral performance based on different task parameters. The fMRI results in healthy people show specific activation patterns within the frontoparietal network associated with inhibition trials (mainly inferior frontal gyrus, insula, cingulate gyrus, SMA, inferior parietal lobule). Further, we present differences between patients with BPD, ADHD and controls in BOLD signal and ERPs.ConclusionsGo/NoGo Task design substantially influences the subjects’ behavioral performance. Our results with methodologically upgraded Go/NoGo Task design provide support for the inhibition frontoparietal brain network and its different activations in BPD and ADHD patients. The research was supported by Ministry of Health of the Czech Republic, grant nr. 15-30062A.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
INTRODUCTION Type 2 diabetes is an enormous medical problem caused by increasing prevalence of the disease and increasing prevalence of severe chronic complications of diabetes. New ADA/EASD guidelines and also Czech diabetes society guidelines enable effective individual approach to the patient. Goal of the therapy is optimal compensation of diabetes and prevention of acute and chronic complications of diabetes and decrease of mortality. Diabetes therapy is started by education in diet a regime combined with metformin. According to the progressive character of the disease it is usually necessary to intensify the therapy by adding antidiabetics from other groups. AIM This study was proposed to analyse the use of therapy algorithm in Czech Republic in patients with insufficient metformin therapy. Secondary objectives were to describe level of compensation of diabetes in time and level of components of the metabolic syndrome in different treatment combinations.Methodic and results: In the sample of 1 516 patients, frequency of use of antidiabetic medication after metformin it was gliflozins 33% and gliptins 28% in the first phase of the study and the number increased later during the study. Median of HbA1c in the beginning of the study was 65 mmol/mol, greatest decrease was found in patents using combination of incretine analogs with metformin - 89 % of them had the HbA1c level < 60 mmol/mol. CONCLUSION The study showed also that antidiabetic drugs used after metformin in Czech Republic are very effective in reducing weight, and improving blood pressure and lipid profile. Therapy using combination of metformin with gliflozins, gliptins or incretin analogs is most effective when metformin is not effective enough.Key words: diabetes type 2 - gliflozins - gliptins - incretine analogs - metformin therapy failure.

Abstract
Regulatory T cell (Treg ) therapy has been exploited in autoimmune disease, solid organ transplantation and in efforts to prevent or treat graft-versus-host disease (GVHD). However, our knowledge on the in-vivo persistence of transfused Treg is limited. Whether Treg transfusion leads to notable changes in the overall Treg repertoire or whether longevity of Treg in the periphery is restricted to certain clones is unknown. Here we use T cell receptor alpha chain sequencing (TCR-α-NGS) to monitor changes in the repertoire of Treg upon polyclonal expansion and after subsequent adoptive transfer. We applied TCR-α-NGS to samples from two patients with chronic GVHD who received comparable doses of stem cell donor derived expanded Treg . We found that in-vitro polyclonal expansion led to notable repertoire changes in vitro and that Treg cell therapy altered the peripheral Treg repertoire considerably towards that of the infused cell product, to different degrees, in each patient. Clonal changes in the peripheral blood were transient and correlated well with the clinical parameters. We suggest that T cell clonotype analyses using TCR sequencing should be considered as a means to monitor longevity and fate of adoptively transferred T cells.

Abstract
OBJECTIVES Several lines of evidence suggest an adverse effect of psychotic episodes on brain morphology. It is not clear if this relationship reflects the cumulative effect of psychotic outbursts on the gradual progressive reduction of hippocampal tissue or an increased tendency toward psychotic episodes in patients with a smaller hippocampus at the beginning of the illness. METHODS This is a longitudinal 4-year prospective study of patients with first-episode schizophrenia (FES, N = 58). Baseline brain anatomical scans (at FES) were analysed using voxel-based morphometry and atlas-based volumetry of the hippocampal subfields. The effects of first-episode duration on the hippocampal morphology, and the effect of baseline hippocampal morphology on illness course with relapses, number of psychotic episodes and residual symptoms were analysed. RESULTS A significant negative correlation was detected between first-episode duration and baseline hippocampal morphology. Relapse, number of psychotic episodes and residual symptoms had no correlation with baseline hippocampal volume. CONCLUSIONS We replicated the effect of psychosis duration on hippocampal volume already at the time first-episode, which supports the concept of toxicity of psychosis. The indices of a later unfavourable course of schizophrenia had no correlation with baseline brain morphology, suggesting that there is no baseline morphological abnormality of the hippocampus that predisposes the patient to frequent psychotic outbursts.

Abstract
BACKGROUND AND PURPOSE Detection and evaluation of ruptured aneurysms is critical for choosing an appropriate endovascular or neurosurgical intervention. Our aim was to assess whether bone-subtraction CTA is capable of guiding treatment for cerebral aneurysms in patients with acute SAH and could replace DSA. MATERIALS AND METHODS We prospectively studied 116 consecutive patients with SAH with 16-detector row bone-subtraction CTA and DSA before intracranial aneurysm treatment. Two independent neuroradiologists reviewed the bone-subtraction CTA blinded to DSA (reference standard). We determined the accuracy of bone-subtraction CTA for aneurysm detection and the measurement of aneurysm dimensions and compared the radiation doses of the 2 imaging modalities. RESULTS Seventy-one patients (61%) had 74 aneurysms on DSA. Bone-subtraction CTA detected 73 of these aneurysms, but it detected 1 additional aneurysm. On a per-aneurysm basis, sensitivity, specificity, and positive and negative predictive values for bone-subtraction CTA were 99%, 98%, and 99% and 98%, respectively. For aneurysms of ≤3 mm, sensitivity was 94% (95% CI, 73%-99%). Bone-subtraction CTA slightly overestimated neck and dome diameters by <0.2 mm and overestimated the dome-to-neck ratios by 2% on average. Dose-length product was 565 ± 201 mGy × cm for bone-subtraction CTA and 1609 ± 1300 mGy × cm for DSA. CONCLUSIONS Bone-subtraction CTA is as accurate as DSA in detecting cerebral aneurysms after SAH, provides similar information about aneurysm configuration and measures, and reduces the average effective radiation dose for vascular diagnostics by 65%. Diagnostic equivalence in association with dose reduction suggests replacing DSA with bone-subtraction CTA in the diagnostic work-up of spontaneous SAH.

Abstract
BACKGROUND/OBJECTIVE High protein oral nutritional supplements (ONS) are regularly prescribed to undernourished patients; however usage of these in older adults is being discussed, as their renal function might have declined with age. Therefore, the aim of the current study was to evaluate the effects of 8 week long consumption of high protein ONS on the renal function of nursing home residents in need of supplementation. Furthermore, within the same setup, differences in gastro-intestinal tolerance between a standard and a more concentrated version of an ONS were investigated. DESIGN Randomized, controlled, single-blind, parallel-group, multi-country trial (NTR2565). SETTING Nursing home. PARTICIPANTS 67 nursing home residents in need of ONS (energy-dense, small volume group n=32; standard volume group n=35). INTERVENTION Protein supplementation was provided by either a standard (200ml, 300kcal, 20g protein) or an energy-dense, small volume (125ml, 300kcal, 18g protein) ONS during the 8 week long study. MEASUREMENTS Primary outcome was gastro-intestinal tolerance, assessed by daily stool frequency and consistency, and occurrence and intensity of self-reported gastro-intestinal symptoms. Safety was measured via the occurrence of (serious) adverse events, vital signs, as well as liver- and kidney function monitoring. RESULTS No clinically relevant and, except for flatulence, no statistically significant differences in gastro-intestinal tolerance were observed between groups. No significant difference between groups was found for estimated glomerular filtration rate (eGFR) and urinary albumin/creatinine ratio at baseline and week 8, nor for the changes from baseline. Adverse events and the changes in monitored renal parameters over the study period did not point to a deterioration of renal function. CONCLUSION High protein ONS seems to be well-tolerated and safe; there is no indication that it affects renal function in nursing home residents, including patients with stage 3 chronic kidney disease, under the conditions tested. Results did not suggest a difference in the effect on renal function between standard and energy-dense small volume ONS format.

Abstract
INTRODUCTION Compliance is important in optimizing the clinical effectiveness of oral nutritional supplements (ONS). Small volume, energy-dense ONS (ED-ONS; ≥ 2 kcal/ml) have been shown to improve compliance in clinical trial settings. However, data from clinical practice is still lacking. The aim of the present study was to evaluate the effect of ED-ONS on the compliance in an observational set-up to obtain data from daily clinical practice on a geriatric ward. METHODS Geriatric inpatients, undernourished or at risk of undernutrition received two servings of either ED-ONS (125 ml, 2.4 kcal/ml: Nutridrink Compact Energy, Nutricia) or a standard ONS (S-ONS; 200 ml, 1.5 kcal/ml: Nutridrink) as part of their daily routine care. Patients were allocated to a group according to availability of beds and placement on the ward. Compliance (kcal/day and % of prescribed volume) was assessed by weighing returned bottles. Data were analyzed via Mixed Model for Repeated Measures. RESULTS Forty-seven patients received ED-ONS, and 61 patients received S-ONS. Compliance was significantly higher with ED-ONS in geriatric inpatients compared to S-ONS ( 378 ± 14.0 kcal/day vs. 337 ± 13.6 kcal/day (mean ± SEM), p = 0.039, 63.0 ± 2.34% vs. 56.2 ± 2.26%, p = 0.039). Moreover, a trend (p=0.078) was observed towards an increasing difference in compliance over time. CONCLUSION This study shows that compliance to ED-ONS is significantly better than to S-ONS in daily clinical practice. Although small, the difference in compliance seems to increase over time, suggesting clinical relevance with longer treatment.

OBJECTIVES An increasing prevalence since 2010 of Serratia marcescens harbouring the Ambler class A carbapenemase SME prompted us to further characterize these isolates. METHODS Isolates harbouring bla(SME) were identified by PCR and sequencing. Phenotypic analysis for carbapenemase activity was carried out by a modified Hodge test and a modified Carba NP test. Antimicrobial susceptibilities were determined by Etest and Vitek 2. Typing was by PFGE of macrorestriction digests. Whole-genome sequencing of three isolates was carried out to characterize the genomic region harbouring the bla(SME)-type genes. RESULTS All S. marcescens harbouring SME-type enzymes could be detected using a modified Carba NP test. Isolates harbouring bla(SME) were resistant to penicillins and carbapenems, but remained susceptible to third-generation cephalosporins, as well as fluoroquinolones and trimethoprim/sulfamethoxazole. Isolates exhibited diverse genetic backgrounds, though 57% of isolates were found in three clusters. Analysis of whole-genome sequence data from three isolates revealed that the bla(SME) gene occurred in a novel cryptic prophage genomic island, SmarGI1-1. CONCLUSIONS There has been an increasing occurrence of S. marcescens harbouring bla(SME) in Canada since 2010. The bla(SME) gene was found on a genomic island, SmarGI1-1, that can be excised and circularized, which probably contributes to its dissemination amongst S. marcescens.
