Lower limb exoskeletons are being used to assist people with movement disorders during activities of daily living or rehabilitation. However, providing a natural interface that automatically adapts to the patient's movement limitations remains an open challenge. In this paper, we present a control implementation that combines a compliant actuator technology with the concept of tacit learning to improve the synchronisation between the exoskeleton and the user during locomotion. We show that this implementation can be effectively used to easily modulate the joint stiffness that is perceived by the user during locomotion...

Autism spectrum disorder (ASD) is a multifaceted neurodevelopmental disorder characterized by a persistence of social and communication impairment, and restricted and repetitive behaviors. However, motor disorders have also been described, but not objectively assessed. Most studies showed inefficient eye-hand coordination and motor learning in children with ASD; in other experiments, mechanisms of acquisition of internal models in self-generated movements appeared to be normal in autism. In this framework, we have developed a robotic protocol, recording gaze and hand data during upper limb tasks, in which a haptic pen-like handle is moved along specific trajectories displayed on the screen...

Mexico, like many low- and middle-income countries (LMICs), faces an epidemic of chronic non-communicable diseases (NCDs), specifically diabetes, hypertension, obesity, and lipid disorders. Many people with these NCDs may not be aware that they have a disease, pointing to the need for broader screening programs. The traditional prevention policy in Mexico was based on screening with a paper-based risk factor questionnaire. However, this was used to screen patients already seeking healthcare services at facilities, and screening goals were set as a function of the number of questionnaires applied, not number of individuals screened...

In the present chapter, we review the literature focusing on oxytocin (OT)-centered research in anxiety spectrum conditions, comprising separation anxiety disorder, specific phobias, social anxiety disorder (SAD), panic disorder, generalized anxiety disorder, and anxiety-related endophenotypes (e.g., trust behavior, behavioral inhibition, neuroticism, and state/trait anxiety). OT receptor gene (OXTR) polymorphisms have been implicated in gene-environment interactions with attachment style and childhood maltreatment and to influence clinical outcomes, including SAD intensity and limbic responsiveness...

Breast cancer survivors are more likely to develop mood disorders and cognitive deficits than women in the general population. Previous studies suggest that peripheral tumors elicit central pro-inflammatory cytokine production, in turn leading to depression and cognitive deficits. In the current study, two cohorts of female Balb/C mice received bilateral orthotopic injections of syngeneic 67NR, 4T07, or 4T1cells (1 × 10(5) cells per injection) to induce mammary tumors. Approximately three weeks later, learned fear (via fear conditioning) or depressive-like behavior (via tail suspension and forced swim test) was assessed...

Neonatal rats were administered a relatively high concentration of ethyl alcohol (11.9% v/v) during postnatal days 4-9, a time when the fetal brain undergoes rapid organizational change and is similar to accelerated brain changes that occur during the third trimester in humans. This model of fetal alcohol spectrum disorders (FASDs) produces severe brain damage, mimicking the amount and pattern of binge-drinking that occurs in some pregnant alcoholic mothers. We describe the use of trace eyeblink classical conditioning (ECC), a higher-order variant of associative learning, to assess long-term hippocampal dysfunction that is typically seen in alcohol-exposed adult offspring...

REVIEW
Mana R Ehlers, Rebecca M Todd
Emotionally arousing events are typically better remembered than mundane ones, in part because emotionally relevant aspects of our environment are prioritized in attention. Such biased attentional tuning is itself the result of associative processes through which we learn affective and motivational relevance of cues. We propose that the locus coeruleus-noradrenaline (LC-NA) system plays an important role in the genesis of attentional biases through associative learning processes as well as their maintenance...

Drooling of saliva is common in children with physical, intellectual and learning disability, and with poor neuromuscular coordination and oral control.(1) It can cause skin breakdown, damage to clothes and equipment and psychosocial problems for the child and family. For many years, glycopyrronium has been prescribed off-label using the injection solution given orally or tablets crushed and suspended in water, or as unlicensed products that were imported or manufactured as pharmaceutical specials.(2,3) In January 2017, a glycopyrronium oral solution (Sialanar-Proveca Limited) became available in the UK as the first licensed product for the treatment of severe drooling (sialorrhoea) in children and adolescents aged 3 years and older with chronic neurological disorders...

Extinction learning is modulated by N-methyl D-aspartate receptors (NMDAR) particularly in prefrontal and hippocampal brain regions. The use of of NMDA agonists in exposure therapy of anxiety disorders has been investigated in various patient groups. Behavioral results showed beneficial effects of pre-learning administration of the partial NMDAR agonist D-Cycloserine (DCS) on therapy success. However, the impact of DCS upon non-fear-related contextual extinction, and associated recruitment of extinction-relevant brain regions is as yet unknown...

Erin M Kerrison
Prison-based therapeutic community (TC) programming is derived from the perspective that drug addiction is primarily symptomatic of cognitive dysfunction, poor emotional management, and underdeveloped self-reliance skills, and can be addressed in a collaborative space where a strong ideological commitment to moral reform and personal responsibility is required of its members. In this space, evidence of rehabilitation is largely centered on the client's relationship to language and the public adoption of a "broken self" narrative...

BACKGROUND: Konzo is an irreversible upper-motor neuron disorder affecting children dependent on bitter cassava for food. The neurocognitive ability of children with konzo over time has yet to be fully documented. METHODS: We did a longitudinal study in a konzo outbreak zone continuously affected by konzo since 1990, in the district of Kahemba, southern Bandundu Province, Congo. We enrolled children with a record of neurological diagnosis of konzo in Kahemba town...

OBJECTIVE: Suicide is a major concern for those afflicted by schizophrenia. Identifying patients at the highest risk for future suicide attempts remains a complex problem for psychiatric interventions. Machine learning models allow for the integration of many risk factors in order to build an algorithm that predicts which patients are likely to attempt suicide. Currently it is unclear how to integrate previously identified risk factors into a clinically relevant predictive tool to estimate the probability of a patient with schizophrenia for attempting suicide...

Pulmonary diseases frequently coexist in heart failure (HF), thus posing diagnostic and therapeutic challenges to cardiologists evaluating patients with overlapping symptoms and implementing recommended HF treatments. There is a growing body of evidence suggesting that pulmonary function testing might provide useful information for the best management of these patients. The availability of portable devices, allowing the measurement of spirometry and lung diffusion capacity for carbon monoxide outside of hospital-based pulmonary lung function laboratories, provides an opportunity for a more widespread use of these measures in the cardiology community, but their interpretation can be challenging...

This study examined the prevalence of learning and psychological diagnoses and associated neurological and personal-environmental risk factors following perinatal and childhood arterial ischemic stroke. In our sample of 126 children and youth, 52.4% received a diagnosis following their assessment. Specifically, 32% had a single diagnosis and 21% had two or more diagnoses. Learning disability, attention deficit-hyperactivity disorder, and intellectual disability were the most prevalent diagnoses. Associated risk factors varied by diagnosis with lower intellectual functioning being the common risk factor across categories...

Women are twice as likely as men to suffer from trauma- and stressor-related disorders. The development of improved therapeutic interventions is contingent upon a more complete grasp of both the neural and behavioral dynamics of the stress response in females. The rodent forced swim test (FST) is a valuable animal model for exploring the neurobiological mechanisms responsible for selection of active and passive responses to inescapable stressors, but it is often neglected in 2-day FST studies is the dissociation of innate (Day 1) versus learned (Day 2) coping responses...

Lisa D'Astolfo, Winfried Rief
Modifying patients' expectations by exposing them to expectation violation situations (thus maximizing the difference between the expected and the actual situational outcome) is proposed to be a crucial mechanism for therapeutic success for a variety of different mental disorders. However, clinical observations suggest that patients often maintain their expectations regardless of experiences contradicting their expectations. It remains unclear which information processing mechanisms lead to modification or persistence of patients' expectations...

REVIEW
Harald Lund, Melanie Pieber, Robert A Harris
While bone marrow-derived Ly6C(hi) monocytes can infiltrate the central nervous system (CNS) they are developmentally and functionally distinct from resident microglia. Our understanding of the relative importance of these two populations in the distinct processes of pathogenesis and resolution of inflammation during neurodegenerative disorders was limited by a lack of tools to specifically manipulate each cell type. During recent years, the development of experimental cell-specific depletion models has enabled this issue to be addressed...

The University of Québec in Montréal has agreements with trade unions providing access to university resources. Researchers involved in this program worked in partnership with union women's and health and safety committees for more than twenty years. Not all studies succeeded in improving women's working conditions. One joint project involved observational studies of tasks done by health-care workers, complemented by interviews and questionnaires. We found that task assignments, movements, postures, and work-related musculoskeletal disorders varied by gender/sex and made recommendations for change...
