BACKGROUND AND PURPOSE: Since GABAergic dysfunction underlies a variety of neurological and psychiatric disorders, numerous strategies leading to the augmentation of GABAergic neurotransmission have been introduced. One of them is the inhibition of GABA reuptake from the synaptic cleft mediated by four plasma membrane GABA transporters (GAT1-4). GAT1 which is exclusively expressed in the brain is an interesting target for centrally acting drugs. In this research, pharmacological properties of a novel, highly potent and selective inhibitor of GAT1, the guvacine derivative named DDPM-2571, were assessed in vivo...

BACKGROUND: The expanded disability status scale (EDSS) is a validated and reliable tool to assess the extent of disabilities in patients with multiple sclerosis (MS). However, the use of this tool has been found to be limited in assessing various symptoms of MS that are important. Our study aimed at evaluating the efficacy of a new scoring system, reverse nutech functional score (RNFS) as compared to EDSS in assessing patients with MS treated with human embryonic stem cell (hESC) therapy...

OBJECTIVE: To assess patients' recollections of in-ICU procedural pain and its impact on post-ICU burden. DESIGN: Prospective longitudinal study of patients who underwent ICU procedures. SETTING: Thirty-four ICUs in France and Belgium. PATIENTS: Two hundred thirty-six patients who had undergone ICU procedures. INTERVENTION: None. MEASUREMENTS AND MAIN RESULTS: Patients were interviewed 3-16 months after hospitalization about: 1) recall of procedural pain intensity and pain distress (on 0-10 numeric rating scale); 2) current pain; that is, having pain in the past week that was not present before hospitalization; and 3) presence of traumatic stress (Impact of Events Scale)...

Most patients with dementia have some behavioural and psychological symptoms. While aggression and agitation are easily recognised, symptoms such as apathy may be overlooked. Behavioural and psychological symptoms should be managed without drugs whenever possible. Although there is little evidence to support their use, antipsychotic drugs are often prescribed to people with dementia. Before prescribing it is important to exclude other causes of altered behaviour, such as pain or infection. Some symptoms may be artefacts of memory loss rather than psychosis...

Sleep is regulated by several brain structures, neurotransmitters and neuromodulators. Endocannabinoids (eCBs) are a group of lipids with modulatory activity in the brain and bind mainly to cannabinoid receptors CB1R and CB2R, thereby modulating several brain functions, (memory, mood, food intake, pain perception). Oleoylethanolamide and palmitoylethanolamide belong to the N-acylethanolamides (NAEs) family, another type of active endogenous lipids. They bind to the peroxisome proliferator-activated receptor α but not to CB1R, thereby modulating food satiety, inflammation and pain...

BACKGROUND: The translation of healthcare research into practice is typically challenging and limited in effectiveness. The Theoretical Domains Framework (TDF) identifies 12 domains of behaviour determinants which can be used to understand the principles of behavioural change, a key factor influencing implementation. The Accelerated Chest pain Risk Evaluation (ACRE) project has successfully translated research into practice, by implementing an intervention to improve the assessment of low to intermediate risk patients presenting to emergency departments (EDs) with chest pain...

Suicide is one of the leading causes of violent death in many countries and its prevention is included in worldwide health objectives. Currently, the DSM-5 considers suicidal behavior as an entity that requires further study. Among the three validators required for considering a psychiatric disorder, there is one based on psychological correlates, biological markers, and patterns of comorbidity. This review includes the most important and recent studies on psychological factors: cognitive, emotional, temperament, and personality correlates (unrelated to diagnostic criteria)...

Brain-derived neurotrophic factor (BDNF) is a member of the neurotrophic factor family of signaling molecules. Since its discovery over three decades ago, BDNF has been identified as an important regulator of neuronal development, synaptic transmission, and cellular and synaptic plasticity and has been shown to function in the formation and maintenance of certain forms of memory. Neural plasticity that underlies learning and memory in the hippocampus shares distinct characteristics with spinal cord nociceptive plasticity...

Being able to remember physically and emotionally painful events in one's own past may shape behavior, and can create an aversion to a variety of situations. Pain imagination is a related process that may include recall of past experiences, in addition to production of sensory and emotional percepts without external stimuli. This study aimed to understand 1) the central nervous system processes that underlie pain imagination, 2) the retrieval of pain memories, and 3) to compare the latter with visual object memory...

BACKGROUND: Diverse group of agro-chemicals are indiscriminately sprayed by the farmers for pest control to enhance crop yield. About 25 million agricultural workers in the developing world suffer from at least one episode of poisoning each year, mainly by anticholinesterase- like organophosphates (OPs). OBJECTIVE: The present study was aimed to establish the OP toxicity in 187 occupationally exposed pesticide sprayers of mango plantation in rural Malihabad, Lucknow, in terms of neuro-cognitive impairment, mental health status, clinical symptoms, diabetes, and hematological factors...

BACKGROUND: Posttraumatic stress disorder (PTSD) might be maintained by deficient extinction memory. We used a cued fear conditioning design with extinction and a post-extinction phase to provoke the return of fear and examined the role of the interplay of amygdala, hippocampus and prefrontal regions. METHODS: We compared 18 PTSD patients with two healthy control groups: 18 trauma-exposed subjects without PTSD (nonPTSD) and 18 healthy controls (HC) without trauma experience...

We have previously observed impairing effects of social defeat stress (CSDS) on inhibitory avoidance (IA) in mice. Given the similarity between changes produced by social stress in animals and symptoms of certain human psychopathologies such as depression and anxiety, the effects of the antidepressant clomipramine on IA impairment produced by CSDS were evaluated in the present study. Male CD1 mice were randomly assigned to the groups: non-stressed+saline, non-stressed+clomipramine, stressed+saline and stressed+clomipramine...

Patients with fibromyalgia experience chronic widespread pain, with associated symptoms of fatigue, sleep disturbance and memory problems. There are many therapies which may be helpful in managing the symptoms of fibromyalgia; however, these often require a process of trial and error to establish optimum management using a combination of pharmacological and non-pharmacological approaches. Nurses can support patients with fibromyalgia using a biopsychosocial approach to symptom management. Understanding the nature of fibromyalgia and management options will enable nurses to deliver holistic patient-centred care...

Hemorrhagic stroke has many symptoms, including central pain, learning and memory impairments, motor deficits, language problems, emotional disturbances, and social maladjustment. Lesions of the ventral basal complex (VBC) of the thalamus elicit thermal and mechanical hyperalgesia, forming an animal model of central post-stroke pain (CPSP). However, no research has yet examined the involvement of learning and memory in CPSP using an animal model. The present study examined whether VBC lesions affect motor function, conditioned place preference (CPP; implicit memory), and spatial learning (explicit memory) in the acquisition and retrieval phases...

OBJECTIVE: Charcot-Marie-Tooth disease (CMT) is a hereditary peripheral neuropathy and belongs to neuromuscular diseases. CMT affects motor function of children, but its clinical expressions are heterogeneous and it could also influence cognitive and psychosocial dimensions of patients. Physical activity is recommended for adults with CMT, but any study has been conducted with children. It is important to propose to children with CMT an adapted physical activity that enables a global approach of the patient...

OBJECTIVE: Among pelvitrochanteric muscles, the internal obturator muscle is implicated in some pain projected at the buttock or perineum. Even though the pathophysiology is not completely understood, its responsibility is often held in clinical practice and in the literature due to effectiveness of botulinum toxin injections, constituting a therapeutic test. The objective is to enhance the couple ultrasound/EMG in difficult injections. MATERIAL/PATIENTS AND METHODS: Eighteen patients were treated in the physical medicine department (Besançon) from September 2015 to February 2016 for gluteal or perineal pain suspected to be related to abnormal spasm of the internal obturator muscle...
