OBJECTIVE: Avoidant/restrictive food intake disorder (ARFID) is a recently named condition to classify patients who present with restricted nutritional intake without body image distortion or fear of weight gain. We sought to compare treatment outcomes of patients with ARFID in a family-centered partial hospital program (PHP) to those with other eating disorders (ED). METHODS: A retrospective chart review of 130 patients 7 to 17 years of age admitted to the program from 2008 to 2012 was performed...

This article interrogates the mainstream healthcare narrative that frames human immunodeficiency virus (HIV) as a chronic disease, and triangulates it with the lived experiences of people with HIV in Singapore. It also examines how HIV patients reconstruct their identities after the diagnosis of HIV. Four HIV patients (two males and two females) were interviewed in depth by an experienced medical social worker. Findings revealed that even as the illness trajectory of HIV has shifted from a terminal condition to a chronic one, living with HIV continues to be fraught with difficulty as society, especially in the Asian context, perceives HIV with much fear and disapproval...

Child maltreatment (CM) is a common condition with a large impact on the victim and society. In the Netherlands, the preventive child healthcare (CHC) aims to protect children against such threats. However, several studies indicate that the efficacy in this area may be suboptimal for many CHC professionals. Therefore, this study aims to map the practice variation in the primary and secondary prevention of CM, by CHC physicians and nurses. This mixed-methods study used interviews to identify relevant topics and develop an online questionnaire...

BACKGROUND: Measuring gastric residual volume (GRV) to guide enteral feeding is a common nursing practice in intensive care units, yet little evidence supports this practice. In addition, this practice has been shown to potentially contribute to inadequate energy delivery in intensive care, which remains a problem in critically ill children. AIMS: We aimed to explore paediatric intensive care nurses' decision-making surrounding this practice. METHODS: This is a cross-sectional electronic survey in a single mixed general and cardiac surgical PICU in the UK...

Rule-governed behavior and its role in generating insensitivity to direct contingencies of reinforcement have been implicated in human psychological suffering. In addition, the human capacity to engage in derived relational responding has also been used to explain specific human maladaptive behaviors, such as irrational fears. To date, however, very little research has attempted to integrate research on contingency insensitivity and derived relations. The current work sought to fill this gap. Across two experiments, participants received either a direct rule (Direct Rule Condition) or a rule that involved a novel derived relational response (Derived Rule Condition)...

Rac1 belongs to the family of Rho GTPases, and plays important roles in the brain function. It affects the cell migration and axon guidance via regulating the cytoskeleton and cellular morphology. However, the effect of its dynamic activation in regulating physiological function remains unclear. Recently, a photoactivatable analogue of Rac1 (PA-Rac1) has been developed, allowing the activation of Rac1 by the specific wavelength of light in living cells. Thus, we constructed recombinant adeno-associated virus (AAV) of PA-Rac1 and its light-insensitive mutant PA-Rac1-C450A under the control of the mouse glial fibrillary acidic protein (mGFAP) promoter to manipulate Rac1 activity in astrocytes by optical stimulation...

PTEN (phosphatase and tensin homology deleted on chromosome 10) has multiple functions, and recent studies have shown that the PTEN family has isoforms. The roles of these PTEN family members in biologic activities warrant specific evaluation. Here, we show that PTENα maintains CaMKII in a state that is competent to induce long-term potentiation (LTP) with resultant regulation of contextual fear memory and spatial learning. PTENα binds to CaMKII with its distinctive N terminus and resets CaMKII to an activatable state by dephosphorylating it at sites T305/306...

BACKGROUND: Living with an allergic disease has consequences for both affected children and their families. The aim of this qualitative study was to gain deeper knowledge of what life is like for families of children with severe allergic disease, in order to improve care and thereby reduce the consequences of living with a chronic disease. METHODS: Four focus group interviews were performed with Swedish parents of children, aged 6-11 and 12-16 years, with severe allergic disease (from one or more allergic conditions, such as food allergy/eczema/hay fever/asthma)...

Non-invasive prenatal testing (NIPT), based on analysis of cell-free foetal DNA, is rapidly becoming a preferred method to screen for chromosomal aneuploidy with the technology now available in over 90 countries. This review provides an up-to-date discussion of the key clinical, social and ethical implications associated with this revolutionary technology. Stakeholders are positive about a test that is highly accurate, safe, can be perfomed early in pregnancy, identifies affected pregnancies that might otherwise have been missed and reduces the need for invasive testing...

Background: Memory-impairment was one of the common characteristics in patients with diabetes mellitus. The release of chronic inflammation mediators and insulin resistance in diabetic brain gave rise to the generation of toxic factor Aβ42 which was the marker of Alzheimer's disease. In addition, the impairment of memory in diabetes mellitus was also correlated predominantly with uptake/metabolism of glucose in medial prefrontal cortex (mPFC). Previously, anti-inflammation and hypoglycemic effects of berberine (BBr) have been described in peripheral tissues...

Bright light can affect mood states and social behaviours. Here, we tested potential interacting effects of light and dopamine on facial emotion recognition. Participants were 32 women with subsyndromal seasonal affective disorder tested in either a bright (3000 lux) or dim light (10 lux) environment. Each participant completed two test days, one following the ingestion of a phenylalanine/tyrosine-deficient mixture and one with a nutritionally balanced control mixture, both administered double blind in a randomised order...

Male-partnered sexual minority women (SMW) have received little research attention, despite the fact that they represent a large proportion of SMW - particularly child-bearing SMW. Male-partnered SMW are less "out" than female-partnered SMW and will likely be "read" as heterosexual by perinatal providers. Given this, and evidence that pregnant women have unique mental health care needs, the current study focuses on male-partnered SMW (n = 28) during the perinatal period, recruited from Toronto, Canada and Massachusetts, USA, in an effort to understand disclosure and concealment processes in general and to perinatal heath care providers specifically...

Recent studies have highlighted a fear or difficulty with the study and understanding of neuroanatomy among medical and healthcare students. This has been linked with a diminished confidence of clinical practitioners and students to manage patients with neurological conditions. The underlying reasons for this difficulty have been queried among a broad cohort of medical, dental, occupational therapy, and speech and language sciences students. Direct evidence of the students' perception regarding specific difficulties associated with learning neuroanatomy has been provided and some of the measures required to address these issues have been identified...

Some animals learn to fear a situation after observing another individual come to harm, and this learning is influenced by the animals' social relationship and history. An important but sometimes overlooked factor in studies of observational fear learning is that social context not only affects observers, but may also influence the behavior and communications expressed by those being observed. Here we sought to investigate whether observational fear learning in the degu (Octodon degus) is affected by social familiarity, and the degree to which vocal expressions of alarm or distress contribute...

Nuclear calcium is an important signaling end-point in synaptic excitation-transcription coupling that is critical for long-term neuroadaptations. Here we show that nuclear calcium acting via a target gene VEGFD is required for hippocampus-dependent fear memory consolidation and extinction in mice. Nuclear calcium-VEGFD signaling upholds structural integrity and complexity of the dendritic arbor of CA1 neurons that renders those cells permissive for the efficient generation of synaptic input-evoked nuclear calcium transients driving the expression of plasticity-related genes...

The lipid sphingosine 1-phosphate (S1P) is a potent neuroprotective signalling molecule that signals through its own family of five G-protein coupled receptors. S1P signalling enhances presynaptic glutamate release and is essential for neural development. S1P is synthesized by the enzymes sphingosine kinases 1 and 2 (SphK1 and SphK2), of which SphK2 mRNA and activity is more abundant in the brain. In this study we investigated the consequences of global SphK2 knockout (SphK2(-/-)) on basic motor capabilities, anxiety, learning, and memory in mice, using a range of tests including the elevated plus maze, the cheeseboard, contextual and cued fear conditioning, and fear extinction...

Adolescence is a period of high risk for the initiation of nicotine product usage and exposure to traumatic events. In parallel, nicotine exposure has been found to age-dependently modulate acquisition of contextual fear memories; however, it is unknown if adolescent nicotine exposure alters extinction of fear related memories. Age-related differences in sensitivity to the effects of nicotine on fear extinction could increase or decrease susceptibility to anxiety disorders. In this study, we examined the effects of acute nicotine administration on extinction and spontaneous recovery of contextual fear memories in pre-adolescent (PND 23), late adolescent (PND 38), and adult (PND 53) C57B6/J mice...

The therapeutic goal for the treatment of posttraumatic stress disorder (PTSD) is to promote extinction and to prevent the relapse of fearful memories. Research has identified pharmacological treatments that may regulate the formation and extinction of fear memories, but not many reagents that block the relapse of extinguished fear are known. Radix Polygalae (RP) is an Asian herb used for sedation, and its ingredients have anxiolytic and antidepressant properties. As various neurological effects have been identified, we tested whether RP affects the relapse of fear...

BACKGROUND: Exposure therapy is an established learning-based intervention for the treatment of anxiety disorders with an average response rate of nearly 50%, leaving room for improvement. Emerging strategies to enhance exposure therapy in humans and fear extinction retention in animal models are primarily pharmacological. These approaches are limited as many patients report preferring non-pharmacological approaches in therapy. With general cognitive enhancement effects, exercise has emerged as a plausible non-pharmacological augmentation strategy...

Across the human life span, fear is often acquired indirectly by observation of the emotional expressions of others. The observational fear conditioning protocol was previously developed as a laboratory model for investigating socially acquired threat responses. This protocol serves as a suitable alternative to the widely used Pavlovian fear conditioning, in which threat responses are acquired through direct experiences. In the observational fear conditioning protocol, the participant (observer) watches a demonstrator being presented with a conditioned stimulus (CS) paired with an aversive unconditioned stimulus (US)...
