STROBE-metagenomics: a STROBE extension statement to guide the reporting of metagenomics studies.
The Lancet. Infectious diseases, 2020

The term metagenomics refers to the use of sequencing methods to simultaneously identify genomic material from all organisms present in a sample, with the advantage of greater taxonomic resolution than culture or other methods. Applications include pathogen detection and discovery, species characterisation, antimicrobial resistance detection, virulence profiling, and study of the microbiome and microecological factors affecting health. However, metagenomics involves complex and multistep processes and there are important technical and methodological challenges that require careful consideration to support valid inference. We co-ordinated a multidisciplinary, international expert group to establish reporting guidelines that address specimen processing, nucleic acid extraction, sequencing platforms, bioinformatics considerations, quality assurance, limits of detection, power and sample size, confirmatory testing, causality criteria, cost, and ethical issues. The guidance recognises that metagenomics research requires pragmatism and caution in interpretation, and that this field is rapidly evolving.
Day-to-Day Change in Pulsatility Index Describes Anterior Cerebral Circulation Disturbance and Functional Outcomes in Pediatric Traumatic Brain Injury.
The Journal of neuroscience nursing : journal of the American Association of Neuroscience Nurses, 2020

Traumatic brain injury (TBI) is a significant source of morbidity and mortality in children. Transcranial Doppler (TCD) ultrasound measures the cerebral arterial circulation allowing for the calculation of pulsatility indices (PIs) that provide an assessment of cerebral blood flow alterations. However, the use of PI in children with TBI is poorly understood and may be an important measure for the nursing care of children.
Empathy Examined From Perspectives of Neuroscience and Artistic Imagination.
The American journal of clinical hypnosis, 2016

This response to Ian E. Wickramasekera II's article, Mysteries of Hypnosis and the Self Are Revealed by the Psychology and Neuroscience of Empathy, is addressed from a joint perspective on consciousness comprising two related orientations: neuroscience and artistic imagination. We find that the central importance of empathy to empathic involvement theory (Wickramasekera II, 2015) reflects the pivotal nature of empathy in the brain and in the relational exchange implicit in the psychotherapeutic process, particularly when using art in therapy. We offer a preliminary unpacking of the roles related to key psychological processes, such as imagination, that are implicated in clinical uses of verbal and visual empathic resonance.
Reading without words or target detection? A re-analysis and replication fMRI study of the Landolt paradigm.
Brain structure & function, 2018

The Landolt paradigm is a visual scanning task intended to evoke reading-like eye-movements in the absence of orthographic or lexical information, thus allowing the dissociation of (sub-) lexical vs. visual processing. To that end, all letters in real word sentences are exchanged for closed Landolt rings, with 0, 1, or 2 open Landolt rings as targets in each Landolt sentence. A preliminary fMRI block-design study (Hillen et al. in Front Hum Neurosci 7:1-14, 2013) demonstrated that the Landolt paradigm has a special neural signature, recruiting the right IPS and SPL as part of the endogenous attention network. However, in that analysis, the brain responses to target detection could not be separated from those involved in processing Landolt stimuli without targets. The present study presents two fMRI experiments testing the question whether targets or the Landolt stimuli per se, led to the right IPS/SPL activation. Experiment 1 was an event-related re-analysis of the Hillen et al. (Front Hum Neurosci 7:1-14, 2013) data. Experiment 2 was a replication study with a new sample and identical procedures. In both experiments, the right IPS/SPL were recruited in the Landolt condition as compared to orthographic stimuli even in the absence of any target in the stimulus, indicating that the properties of the Landolt task itself trigger this right parietal activation. These findings are discussed against the background of behavioural and neuroimaging studies of healthy reading as well as developmental and acquired dyslexia. Consequently, this neuroimaging evidence might encourage the use of the Landolt paradigm also in the context of examining reading disorders, as it taps into the orientation of visual attention during reading-like scanning of stimuli without interfering sub-lexical information.
Vestibular mapping in patients with unilateral peripheral-vestibular deficits.
Neurology, 2020

To test the hypothesis that patterns of semicircular canal (SCC) and otolith impairment in unilateral vestibular loss depend on the underlying disorders, we analyzed peripheral-vestibular function of all 5 vestibular sensors.
Menopause Representations Questionnaire: development and validation with Portuguese women.
Climacteric : the journal of the International Menopause Society, 2021

This study aimed to develop and validate a Portuguese version of the Menopause Representations Questionnaire (MenoSentations-Q), a self-report measure to assess cognitive appraisal of menopause, based on cognitive components of the Self-Regulation Model and the results from a previous Portuguese qualitative study.
A TREK to Translate Genetics to Mechanisms of Migraine.
Neuron, 2019

In this issue of Neuron, Royal et al. (2018) find that a mutant form of the TRESK ion channel linked to migraine undergoes alternative translation to produce an inhibitory protein that blocks TREK channels, leading to neuronal hyperexcitability and migraine in rodents.
The right to smoke and the right to smoke-free surroundings: international comparison of smoke-free psychiatric clinic implementation experiences.
BJPsych open, 2021

In Scandinavia, people with a severe mental disorder have a reduced life expectancy of 15-20 years compared with the general public. Smoking is a major contributor, and smoke-free policies are increasingly adopted in psychiatric clinics around the world. We compared potential facilitators and barriers among staff and management, for the implementation of smoke-free psychiatric clinics.
Microglia Regulate Cell Genesis in a Sex-dependent Manner in the Neonatal Hippocampus.
Neuroscience, 2021

Microglia, the innate immune cells of the brain, regulate brain development through many processes such as synaptic pruning, supporting cell genesis and phagocytosing living and dying cells. There are sex differences in these same developmental processes throughout the brain, thus microglia may contribute to brain sex differences. We examined whether microglia support a known sex difference in neonatal hippocampal neurogenesis and whether juvenile hippocampal neurogenesis was impacted by the loss of neonatal microglia. We used central infusion of liposomal clodronate to selectively deplete microglia and found decreased cell genesis in the male, but not female, dentate gyrus and hippocampus. We found that loss of microglia decreased cell genesis in the cortex and amygdala of both males and females. We assessed the expression of several cytokines and growth factors that have previously been shown to support cell genesis. We found that expression of Il1b and Tnf were decreased in the hippocampus due to microglia depletion however, there were no sex differences in the expression of any immune genes. In adolescence, there was an increase in the number of mitotic cells in the subgranular zone of the dentate gyrus of previously microglia depleted rats however, the number of newly-born neurons was unchanged in the adolescent animals. We also sought to determine whether there was a sex difference in the number of progenitor cells in the dentate gyrus in the neonatal period. We found no sex differences in the number of progenitor cells. Overall, these studies show that microglia are important for regulating region-specific sex differences in cell genesis in the developing brain.
Fifteen-minute consultation: A clinical approach to the management of the child with hypertonia.
Archives of disease in childhood. Education and practice edition, 2020

Elevated tone (hypertonia) is a common problem seen in the paediatric clinic. For most children and young people, hypertonia is just one aspect of a broader disorder of movement and posture. This paper describes a clinical approach to the management of hypertonia in children, considering the contribution of high tone to the functional problems experienced by the child, the potential adverse effects of reducing tone, side effects of the intervention and the importance of setting objectives/goals for intervention which can be measured at follow-up. We describe this as the 'MOTOR' approach and provide some examples of how it can be used in practice.
[Medical devices correcting the deafness: Hearing aids and auditory implants].
Presse medicale (Paris, France : 1983), 2017

The management of deafness has become a major public health issue as their lack of detection has a deleterious effect in children and increases the risk factors for aggravation of other pathologies in adults. The detection of deafness remains a real challenge: in the newborn, systematic screening at birth is a good strategy, in adults, much remains to be done. The functional rehabilitation of deafness is based on the use of hearing aids by aerial or bone conduction or of auditory implants. There are three types of auditory implants available: bone anchored hearing implants, middle ear implants and cochlear implants. Many actors, in particular social organizations, can intervene in the financial management of these medical devices.
Comparison of soluble ICAM-1, VCAM-1 and E-selectin levels in patients with episodic cluster headache and giant cell arteritis.
Cephalalgia : an international journal of headache, 2008

The pathophysiology of cluster headache (CH) is supposed to involve the lower posterior part of the hypothalamus, the trigeminal nerve, autonomic nerves and vessels in the orbital/retro-orbital region. The exact connection of this hypothalamic-trigemino-autonomic-vascular axis is not fully understood. The presence of inflammation in the perivascular tissue of the retro-orbital region has been presented as a possible mechanism behind the pain and the sympatheticoplegia sometimes observed during headache attacks. In a previous study we found neither increased levels of erythrocyte sedimentation rate, C-reactive protein or acute-phase reactants nor clinical signs of a generalized inflammatory disorder. However, these tests may not be sensitive enough to detect a focal inflammatory process in the retro-orbital region. In the present study, we analysed serum levels of three soluble adhesion molecules; soluble intercellular adhesion molecule-1 (sICAM-1), soluble vascular cell adhesion molecule-1 (sVCAM-1) and soluble E-selectin (sE-selectin) in patients with episodic CH and in patients with biopsy-positive giant cell arteritis (GCA), a known vasculitic disorder of large and medium-sized arteries. A control group of healthy volunteers was also included. Within the CH group, sICAM-1, sVCAM-1 and sE-selectin showed an increasing trend in remission compared with the active CH period, but the difference was statistically significant for sE-selectin only. The mean sICAM-1 value was higher in patients with active GCA than in CH patients during the active cluster period. Compared with the healthy control group, the mean levels of soluble adhesion molecules in CH patients also tended to be higher, but statistically significantly so only for sVCAM-1. We hypothesize that CH is not a vasculitic disorder of the medium-sized arteries, but CH patients may have an immune response that reacts differently from that of healthy volunteers.
Pupillary responses and reaction times index different cognitive processes in a combined Go/Switch incidental learning task.
Neuropsychologia, 2019

In previous studies we have provided evidence that performance in speeded response tasks with infrequent target stimuli reflects both automatic and controlled cognitive processes, based on differences in reaction time (RT) and task-related brain responses (Cheyne et al. 2012, Isabella et al. 2015). Here we test the hypothesis that such shifts in cognitive control may be influenced by changes in cognitive load related to stimulus predictability, and that these changes can be indexed by task-evoked pupillary responses (TEPR). We manipulated stimulus predictability using fixed stimulus sequences that were unknown to the participants in a Go/Switch task (requiring a switch response on 25% of trials) while monitoring TEPR as a measure of cognitive load in 12 healthy adults. Results showed significant improvement in performance (reduced RT, increased efficiency) for repeated sequences compared to occasional deviant sequences (10% probability) indicating that incidental learning of the predictable sequences facilitated performance. All behavioral measures varied between Switch and Go trials (RT, efficiency), however mean TEPR amplitude (mTEPR) and latency to maximum pupil dilation were particularly sensitive to Go/Switch. Results were consistent with the hypothesis that mTEPR indexes cognitive load, whereas TEPR latency indexes time to response selection, independent from response execution. The present study provides evidence that incidental pattern learning during response inhibition tasks may modulate several cognitive processes including cognitive load, effort, response selection and execution, which can in turn have differential effects on measures of performance. In particular, we demonstrate that reaction time may not be indicative of underlying cognitive load.
Jean Rodier: History of Manganism in Morocco.
Neurotoxicology, 2020

Jean Rodier (1920-2003), distinguished researcher and scientist, directed the Toxicology Department of Hygiene Institute of Rabat under the French Protectorate. From 1946, he developed numerous lines of research in occupational health, in particular on Manganism, a neurological disorder that impacted miners in his home country of Morocco. His many papers on Manganism, only one of which was published in English, describe field and laboratory research studies that focused its prevention and management.
The effect of motor and cognitive placebos on the serial reaction time task.
The European journal of neuroscience, 2021

Motor learning is a key component of human motor functions. Repeated practice is essential to gain proficiency over time but may induce fatigue. The aim of this study was to determine whether motor performance and motor learning (as assessed with the serial reaction time task, SRTT) and perceived fatigability (as assessed with subjective scales) are improved after two types of placebo interventions (motor and cognitive). A total of 90 healthy volunteers performed the SRTT with the right hand in three sessions (baseline, training and final). Before the training and the final session, one group underwent a motor-related placebo intervention in which inert electrical stimulation (TENS) was applied over the hand and accompanied by verbal suggestion that it improves movement execution (placebo-TENS). The other group underwent a cognitive-related placebo intervention in which sham transcranial direct current stimulation (tDCS) was delivered to the supraorbital area and accompanied by verbal suggestion that it increases attention (placebo-tDCS). A control group performed the same task without receiving treatment. Overall better performance on the SRTT (not ascribed to sequence-specific learning) was noted for the placebo-TENS group, which also reported less perceived fatigability at the physical level. The same was observed in a subgroup tested 24 hr later. The placebo-tDCS group reported less perceived fatigability, both at the mental and physical level. These findings indicate that motor- and cognitive-related placebo effects differently shape motor performance and perceived fatigability on a repeated motor task.
Dynamic brain fluctuations outperform connectivity measures and mirror pathophysiological profiles across dementia subtypes: A multicenter study.
NeuroImage, 2021

From molecular mechanisms to global brain networks, atypical fluctuations are the hallmark of neurodegeneration. Yet, traditional fMRI research on resting-state networks (RSNs) has favored static and average connectivity methods, which by overlooking the fluctuation dynamics triggered by neurodegeneration, have yielded inconsistent results. The present multicenter study introduces a data-driven machine learning pipeline based on dynamic connectivity fluctuation analysis (DCFA) on RS-fMRI data from 300 participants belonging to three groups: behavioral variant frontotemporal dementia (bvFTD) patients, Alzheimer's disease (AD) patients, and healthy controls. We considered non-linear oscillatory patterns across combined and individual resting-state networks (RSNs), namely: the salience network (SN), mostly affected in bvFTD; the default mode network (DMN), mostly affected in AD; the executive network (EN), partially compromised in both conditions; the motor network (MN); and the visual network (VN). These RSNs were entered as features for dementia classification using a recent robust machine learning approach (a Bayesian hyperparameter tuned Gradient Boosting Machines (GBM) algorithm), across four independent datasets with different MR scanners and recording parameters. The machine learning classification accuracy analysis revealed a systematic and unique tailored architecture of RSN disruption. The classification accuracy ranking showed that the most affected networks for bvFTD were the SN + EN network pair (mean accuracy = 86.43%, AUC = 0.91, sensitivity = 86.45%, specificity = 87.54%); for AD, the DMN + EN network pair (mean accuracy = 86.63%, AUC = 0.89, sensitivity = 88.37%, specificity = 84.62%); and for the bvFTD vs. AD classification, the DMN + SN network pair (mean accuracy = 82.67%, AUC = 0.86, sensitivity = 81.27%, specificity = 83.01%). Moreover, the DFCA classification systematically outperformed canonical connectivity approaches (including both static and linear dynamic connectivity). Our findings suggest that non-linear dynamical fluctuations surpass two traditional seed-based functional connectivity approaches and provide a pathophysiological characterization of global brain networks in neurodegenerative conditions (AD and bvFTD) across multicenter data.
Twenty years of ISAREN: an amphibian biologist in Wonderland.
General and comparative endocrinology, 2010

The 6th International Symposium on Amphibian and Reptilian Endocrinology and Neurobiology (ISAREN), the former International Symposium on Amphibian Endocrinology (ISAE), was recently held in Berlin. ISAREN developed from two symposia on amphibian biology held in European countries in 1988-1990. In this article, the history of ISAREN was briefly stated. In addition, some of the topics of our researches carried out in collaboration with several groups, using various amphibian species during the past 20 years and/or presented in the past symposia were reviewed. The topics included the discovery of pancreatic chitinase, involvement of growth hormone in vitellogenin synthesis, changes of ANF-like immunoreactivity in the frogs sent into the space, discovery of a peptide sex-pheromone, origin of the epithelial pituitary, and hypothalamic regulation of thyroid-stimulating hormone.
Angelman Syndrome: From Mouse Models to Therapy.
Neuroscience, 2020

The UBE3A gene is part of the chromosome 15q11-q13 region that is frequently deleted or duplicated, leading to several neurodevelopmental disorders (NDD). Angelman syndrome (AS) is caused by the absence of functional maternally derived UBE3A protein, while the paternal UBE3A gene is present but silenced specifically in neurons. Patients with AS present with severe neurodevelopmental delay, with pronounced motor deficits, absence of speech, intellectual disability, epilepsy, and sleep problems. The pathophysiology of AS is still unclear and a treatment is lacking. Animal models of AS recapitulate the genotypic and phenotypic features observed in AS patients, and have been invaluable for understanding the disease process as well as identifying apropriate drug targets. Using these AS mouse models we have learned that loss of UBE3A probably affects many areas of the brain, leading to increased neuronal excitability and a loss of synaptic spines, along with changes in a number of distinct behaviours. Inducible AS mouse models have helped to identify the critical treatment windows for the behavioral and physiological phenotypes. Additionally, AS mouse models indicate an important role for the predominantly nuclear UBE3A isoform in generating the characteristic AS pathology. Last, but not least, the AS mice have been crucial in guiding Ube3a gene reactivation treatments, which present a very promising therapy to treat AS.
[A case of chronic sarcoid myopathy with Basedow's disease and Sjogren's syndrome: A case series of sarcoid myopathy].
Rinsho shinkeigaku = Clinical neurology, 2017

We report a 62-year-old woman with a history of Basedow's disease and Sjogren's syndrome who presented with slowly progressive limb muscle weakness over the course of ten years. On physical examination, she had dry eye and mouth, but was otherwise normal. Neurological examination revealed symmetrical proximal dominant muscle weakness. Polymyositis was suspected at initial diagnosis due to her clinical course, physical examination, and autoimmune disease. However, the final diagnosis based on a muscle biopsy was the chronic myopathic type of sarcoid myopathy. Among 25 definite sarcoid myopathy cases in the National Center of Neurology and Psychiatry muscle repository from 2010 to 2015, 6/25 had autoimmune diseases. All 6 patients were female and had the chronic myopathic type of sarcoid myopathy. The number of patients with Sjogren's syndrome, thyroid disease, autoimmune hepatitis, and idiopathic thrombocytopenia were 4, 1, 1, and 1, respectively. Only the present case had both thyroid disease and Sjogren's syndrome. In conclusion, the chronic myopathic type of sarcoid myopathy is one possibility to consider in patients who present with progressive myopathy together with autoimmune diseases.
Isolating the role of time in bed restriction in the treatment of insomnia: a randomized, controlled, dismantling trial comparing sleep restriction therapy with time in bed regularization.
Sleep, 2020

Sleep restriction therapy (SRT) is one of the most effective treatments for insomnia. Restriction of time in bed (TIB) is assumed to be the central mechanism through which SRT improves sleep consolidation and reduces insomnia symptoms. This hypothesis has never been directly tested. We designed a randomized, controlled, dismantling trial in order to isolate the role of TIB restriction in driving both clinical and polysomnographic sleep outcomes.
Injection pressure monitoring during peripheral nerve blocks: from bench to operating theatre.
Anaesthesia, critical care & pain medicine, 2020

Nerve damage can occur after ultrasound-guided peripheral nerve block (PNB). Injection pressure monitoring could improve the safety of PNB. The aim was to analyse parameters affecting pressure measurements during PNB.
