وَيَوۡمَ يُنفَخُ فِي ٱلصُّورِ فَفَزِعَ مَن فِي ٱلسَّمَٰوَٰتِ وَمَن فِي ٱلۡأَرۡضِ إِلَّا مَن شَآءَ ٱللَّهُۚ وَكُلٌّ أَتَوۡهُ دَٰخِرِينَ
On the Day the Trumpet sounds, everyone in heaven and on earth will be terrified- except such as God wills- and all will come to Him in utter humility
مَن جَآءَ بِٱلۡحَسَنَةِ فَلَهُۥ خَيۡرࣱ مِّنۡهَا وَهُم مِّن فَزَعࣲ يَوۡمَئِذٍ ءَامِنُونَ
whoever comes with a good deed will be rewarded with something better, and be secure from the terrors of that Day
وَلَا تَنفَعُ ٱلشَّفَٰعَةُ عِندَهُۥٓ إِلَّا لِمَنۡ أَذِنَ لَهُۥۚ حَتَّىٰٓ إِذَا فُزِّعَ عَن قُلُوبِهِمۡ قَالُواْ مَاذَا قَالَ رَبُّكُمۡۖ قَالُواْ ٱلۡحَقَّۖ وَهُوَ ٱلۡعَلِيُّ ٱلۡكَبِيرُ

Commentary on the verses above, at most two editions per verse.
The greatest terror shall not make them sorrow, and the angels will receive them: “This is the day that you were promised.” On the Day of Resurrection in the greatest gathering place and most tremendous courtyard, they will not hear from the angels the call “no good news” [25:22], nor the address, “Stand apart today, O offenders!” [36:59], nor the harsh call, “Slink into it, and do not talk to Me!” [23:108]. They will not hear the call of separation's pain, nor will they despair of mercy. Rather the angels will keep on coming, company after company, and they will give the good news: “This is the day that you were promised,” that is, “This is the day in which you have the promised reward.” Among them are those who will be received by the angels, and among them are those who will be addressed and made known by the King. God will say, “My servants, have you been yearning for Me?” He will sa

Extending animal models of fear conditioning to humans.: A goal of fear and anxiety research is to understand how to treat the potentially devastating effects of anxiety disorders in humans. Much of this research utilizes classical fear conditioning, a simple paradigm that has been extensively investigated in animals, helping outline a brain circuitry thought to be responsible for the acquisition, expression and extinction of fear. The findings from non-human animal research have more recently been substantiated and extended in humans, using neuropsyc
Fear extinction in rats: implications for human brain imaging and anxiety disorders.: Fear extinction is the decrease in conditioned fear responses that normally occurs when a conditioned stimulus (CS) is repeatedly presented in the absence of the aversive unconditioned stimulus (US). Extinction does not erase the initial CS-US association, but is thought to form a new memory. After extinction training, extinction memory competes with conditioning memory for control of fear expression. Deficits in fear extinction are thought to contribute to post-traumatic stress disorder (PTSD).
Presence and acquired origin of reduced recall for fear extinction in PTSD: results of a twin study.: Recall of fear extinction, which is thought to aid in recovery from a psychologically traumatic event, is hypothesized to be deficient in post-traumatic stress disorder (PTSD), but this has not yet been demonstrated in the laboratory, nor has its origin been investigated. To address these two issues, 14 pairs of monozygotic twins discordant for combat exposure, in 7 of which the combat-exposed twin had PTSD, underwent a two-day fear conditioning and extinction procedure. On Day 1, subjects viewe
The effects of transcutaneous vagus nerve stimulation on conditioned fear extinction in humans.: A critical component of the treatment for anxiety disorders is the extinction of fear via repeated exposure to the feared stimulus. This process is strongly dependent on successful memory formation and consolidation. Stimulation of the vagus nerve enhances memory formation in both animals and humans. The objective of this study was to assess whether transcutaneous stimulation of the vagus nerve (tVNS) can accelerate extinction memory formation and retention in fear conditioned humans. To assess
Neural signatures of conditioning, extinction learning, and extinction recall in posttraumatic stress disorder: a meta-analysis of functional magnetic resonance imaging studies.: Background: Establishing neurobiological markers of posttraumatic stress disorder (PTSD) is essential to aid in diagnosis and treatment development. Fear processing deficits are central to PTSD, and their neural signatures may be used as such markers. Methods: Here, we conducted a meta-analysis of seven Pavlovian fear conditioning fMRI studies comparing 156 patients with PTSD and 148 trauma-exposed healthy controls (TEHC) using seed-based d-mapping, to contrast neural correlates of experimental
Role of Human Ventromedial Prefrontal Cortex in Learning and Recall of Enhanced Extinction.: Standard fear extinction relies on the ventromedial prefrontal cortex (vmPFC) to form a new memory given the omission of threat. Using fMRI in humans, we investigated whether replacing threat with novel neutral outcomes (instead of just omitting threat) facilitates extinction by engaging the vmPFC more effectively than standard extinction. Computational modeling of associability (indexing surprise strength and dynamically modulating learning rates) characterized skin conductance responses and vm
Current approaches to managing fear of cancer recurrence; a descriptive survey of psychosocial and clinical health professionals.
Objective: Fear of cancer recurrence (FCR) is common amongst cancer survivors and help with this problem is the most frequently reported unmet need in this population. This study investigated how FCR is perceived and managed by clinical health professionals (medical and nursing staff) and psychosocial professionals in oncology settings. Methods: Clinical health professionals and psychosocial professionals in oncology settings received emailed invitations from their professional organisation to participate in an online survey. Results: Data from 77 clinical health professionals and 64 psychosocial professionals indicate that FCR is perceived as common and challenging to manage. Thirty-one percent of psychosocial professionals estimated FCR is present in >50% of cancer survivors seen in their practise. Only a minority (21%) of clinical staff reported always referring patients with high lev…

Rapid fear detection relies on high spatial frequencies.
Signals of threat--such as fearful faces--are processed with priority and have privileged access to awareness. This fear advantage is commonly believed to engage a specialized subcortical pathway to the amygdala that bypasses visual cortex and processes predominantly low-spatial-frequency information but is largely insensitive to high spatial frequencies. We tested visual detection of low- and high-pass-filtered fearful and neutral faces under continuous flash suppression and sandwich masking, and we found consistently that the fear advantage was specific to high spatial frequencies. This demonstrates that rapid fear detection relies not on low- but on high-spatial-frequency information--indicative of an involvement of cortical visual areas. These findings challenge the traditional notion that a subcortical pathway to the amygdala is essential for the initial processing of fear signals a…

Epigenetic priming of memory updating during reconsolidation to attenuate remote fear memories.
Traumatic events generate some of the most enduring forms of memories. Despite the elevated lifetime prevalence of anxiety disorders, effective strategies to attenuate long-term traumatic memories are scarce. The most efficacious treatments to diminish recent (i.e., day-old) traumata capitalize on memory updating mechanisms during reconsolidation that are initiated upon memory recall. Here, we show that, in mice, successful reconsolidation-updating paradigms for recent memories fail to attenuate remote (i.e., month-old) ones. We find that, whereas recent memory recall induces a limited period of hippocampal neuroplasticity mediated, in part, by S-nitrosylation of HDAC2 and histone acetylation, such plasticity is absent for remote memories. However, by using an HDAC2-targeting inhibitor (HDACi) during reconsolidation, even remote memories can be persistently attenuated. This intervention …

Barriers and facilitators to self-care communication during medical appointments in the United States for adults with type 2 diabetes.
Objective: Diabetes self-care is challenging and requires effective patient-provider communication to achieve optimal treatment outcomes. This study explored perceptions of barriers and facilitators to diabetes self-care communication during medical appointments. Design: Qualitative study using in-depth interviews with a semistructured interview guide. Participants: Thirty-four patients with type 2 diabetes and 19 physicians who treat type 2 diabetes. Results: Physicians described some patients as reluctant to discuss their self-care behaviors primarily because of fear of being judged, guilt, and shame. Similarly, patients described reluctant communication resulting from fear of being judged and shame, particularly shame surrounding food intake and weight. Physicians and patients recommended trust, nonjudgmental acceptance, open/honest communication, and providing patients hope for livin…

Rethinking the role of worry in generalized anxiety disorder: evidence supporting a model of emotional contrast avoidance.
The Contrast Avoidance model (Newman & Llera, 2011) proposes that individuals with generalized anxiety disorder (GAD) are hypersensitive to sharp upward shifts in negative emotion that typically accompany negative events, and use worry to maintain sustained intrapersonal negativity in an attempt to avoid these shifts. Although research shows that worry increases negative emotionality and mutes further emotional reactivity to a stressor when compared to the worry period (e.g., Llera & Newman, 2010), no study has tracked changes in negative emotionality from baseline to worry inductions followed by a range of emotional exposures. Further, no study has yet assessed participants' subjective appraisals of prior worry on helping to cope with such exposures. The present study tested the main tenets of the Contrast Avoidance model by randomly assigning participants with GAD (n=48) and nonanxious…

Binge-like consumption of a palatable food accelerates habitual control of behavior and is dependent on activation of the dorsolateral striatum.
Access to highly palatable and calorically dense foods contributes to increasing rates of obesity worldwide. Some have made the controversial argument that consumption of such foods can lead to "food addiction," yet little is known about how long-term access to highly palatable foods might alter goal-directed learning and decision making. In the following experiments, rats were given 5 weeks of continuous or restricted daily access to sweetened condensed milk (SCM) before instrumental training for food reward. Subsequently we examined whether goal-directed performance was impaired in these groups using the outcome-devaluation task. Control rats reduced responding following devaluation of the earned outcome as did those with previous continuous access to SCM. Of interest, rats with previous restricted access to SCM responded similarly under the devalued and nondevalued conditions, indicat…

A role for primate subgenual cingulate cortex in sustaining autonomic arousal.
The subgenual anterior cingulate cortex (subgenual ACC) plays an important role in regulating emotion, and degeneration in this area correlates with depressed mood and anhedonia. Despite this understanding, it remains unknown how this part of the prefrontal cortex causally contributes to emotion, especially positive emotions. Using Pavlovian conditioning procedures in macaque monkeys, we examined the contribution of the subgenual ACC to autonomic arousal associated with positive emotional events. After such conditioning, autonomic arousal increases in response to cues that predict rewards, and monkeys maintain this heightened state of arousal during an interval before reward delivery. Here we show that although monkeys with lesions of the subgenual ACC show the initial, cue-evoked arousal, they fail to sustain a high level of arousal until the anticipated reward is delivered. Control pro…

Finding theory- and evidence-based alternatives to fear appeals: Intervention Mapping.
Fear arousal-vividly showing people the negative health consequences of life-endangering behaviors-is popular as a method to raise awareness of risk behaviors and to change them into health-promoting behaviors. However, most data suggest that, under conditions of low efficacy, the resulting reaction will be defensive. Instead of applying fear appeals, health promoters should identify effective alternatives to fear arousal by carefully developing theory- and evidence-based programs. The Intervention Mapping (IM) protocol helps program planners to optimize chances for effectiveness. IM describes the intervention development process in six steps: (1) assessing the problem and community capacities, (2) specifying program objectives, (3) selecting theory-based intervention methods and practical applications, (4) designing and organizing the program, (5) planning, adoption, and implementation,…

Adolescent alcohol exposure reduces behavioral flexibility, promotes disinhibition, and increases resistance to extinction of ethanol self-administration in adulthood.
The prefrontal cortex (PFC) is a brain region that is critically involved in cognitive function and inhibitory control of behavior, and adolescence represents an important period of continued PFC development that parallels the maturation of these functions. Evidence suggests that this period of continued development of the PFC may render it especially vulnerable to environmental insults that impact PFC function in adulthood. Experimentation with alcohol typically begins during adolescence when binge-like consumption of large quantities is common. In the present study, we investigated the effects of repeated cycles of adolescent intermittent ethanol (AIE) exposure (postnatal days 28-42) by vapor inhalation on different aspects of executive functioning in the adult rat. In an operant set-shifting task, AIE-exposed rats exhibited deficits in their ability to shift their response strategy wh…

Behavioral and neural substrates of habit formation in rats intravenously self-administering nicotine.
Tobacco addiction involves a transition from occasional, voluntary smoking towards habitual behavior that becomes increasingly resistant to quitting. The development of smoking habits may reflect a loss of behavioral control that can be modeled in rats. This study investigated the behavioral and neural substrates of habit formation in rats exposed to either brief (10 days) or extended (47 days) intravenous (IV) nicotine self-administration training. Following training, the first cohort of rats were exposed to a nicotine devaluation treatment, which involved repeated pairings of IV nicotine with lithium injection. They were then tested for sensitivity of responding to nicotine devaluation under extinction and reinstatement conditions. The second cohort of rats received equivalent self-administration training followed by processing of brain tissue for c-Fos immunohistochemistry. After brie…

Living in negotiation: patients' experiences of being in the diagnostic process of COPD.
Purpose: To illuminate patients' lived experiences of going through the process of being diagnosed with chronic obstructive pulmonary disease (COPD). Patients and methods: A phenomenological-hermeneutic analysis was applied in the interpretation of interviews with eight persons diagnosed with mild or moderate COPD. Results: One main theme 'living in negotiation', and three themes 'living with a body out of step with the diagnosis', 'dealing with the past', and 'being challenged by the future' reflected the process participants were living through in their quest for acceptance and a new balance in life. Participants found that the diagnostic processes were confusing, and that the diagnosis itself was 'a slap in the face'. Unclear messages gave rise to fluctuating between an understanding of the condition as 'not too severe', insecurity, and fear. Shame and guilt related to the diagnosis h…

Altered emotion perception in insomnia disorder.
Study objectives: Chronic insomnia is a prevalent sleep disorder that negatively affects daytime functioning and confers risk for the future development of psychiatric disorder. Patients with insomnia often report problems with emotion regulation and impaired social interactions. Moreover, experimental sleep loss in healthy adults is associated with altered reactivity to and interpretation of emotional information. In the current study, we investigated socioemotional processing in patients with chronic insomnia disorder relative to healthy good sleepers. Design: Between-groups comparison. Setting: Sleep Research Laboratory. Participants: Patients with well-defined psychophysiological insomnia (PI; n = 16), free from psychiatric disorder, and an age- and sex-matched control group of good sleepers (GS; n = 15). Interventions: N/A. Measurement and results: All participants completed a facia…

'The living death of Alzheimer's' versus 'Take a walk to keep dementia at bay': representations of dementia in print media and carer discourse.
Understanding dementia is a pressing social challenge. This article draws on the 'Dementia talking: care conversation and communication' project which aims to understand how talk about, and to people living with dementia is constructed. In this article I draw on the construction of dementia manifest in two data sets - a corpus of 350 recent UK national newspaper articles and qualitative data derived from in-depth interviews with informal carers. These data were analysed using a thematic discursive approach. A 'panic-blame' framework was evident in much of the print media coverage. Dementia was represented in catastrophic terms as a 'tsunami' and 'worse than death', juxtaposed with coverage of individualistic behavioural change and lifestyle recommendations to 'stave off' the condition. Contrary to this media discourse, in carers' talk there was scant use of hyperbolic metaphor or referen…

Shared mushroom body circuits underlie visual and olfactory memories in Drosophila.
In nature, animals form memories associating reward or punishment with stimuli from different sensory modalities, such as smells and colors. It is unclear, however, how distinct sensory memories are processed in the brain. We established appetitive and aversive visual learning assays for Drosophila that are comparable to the widely used olfactory learning assays. These assays share critical features, such as reinforcing stimuli (sugar reward and electric shock punishment), and allow direct comparison of the cellular requirements for visual and olfactory memories. We found that the same subsets of dopamine neurons drive formation of both sensory memories. Furthermore, distinct yet partially overlapping subsets of mushroom body intrinsic neurons are required for visual and olfactory memories. Thus, our results suggest that distinct sensory memories are processed in a common brain center. S…

Comorbidity of fear of progression and anxiety disorders in cancer patients.
Objective: The relation between fear of progression (FoP) and anxiety disorders remains unclear. Therefore, we investigated the comorbidity between clinical FoP and psychiatric anxiety disorders. Method: In this cross-sectional study, 341 cancer patients undergoing acute inpatient care participated. A structured clinical interview (Structured Clinical Interview for DSM-IV Axis I) was used to identify Diagnostic and Statistical Manual of Mental Disorders: Fourth Edition anxiety disorders and hypochondriasis. Patients completed measures of FoP (Fear of Progression Questionnaire), worries (Penn State Worry Questionnaire, Worry Domains Questionnaire), depression [Patient Health Questionnaire (PHQ): Depression], anxiety (PHQ: General Anxiety Disorder) and somatic symptoms (PHQ: Somatic Symptoms). We cross-tabulated FoP with the presence of anxiety disorders and studied associated variables. R…

Cancer symptom awareness and barriers to medical help seeking in Scottish adolescents: a cross-sectional study.
Background: Initiatives to promote early diagnosis include raising public awareness of signs and symptoms of cancer and addressing barriers to seeking medical help about cancer. Awareness of signs and symptoms of cancer and emotional barriers, such as fear, worry, and embarrassment, strongly influence help seeking behaviour. Whether anxiety influences seeking medical help about cancer is not known. The purpose of this study about adolescents was to examine: 1) the relationship between contextual factors and awareness of signs and symptoms of cancer and barriers (including emotional barriers) to seeking medical help, and 2) associations between anxiety and endorsed barriers to seeking medical help. Interpretation of data is informed by the common sense model of the self-regulation of health and illness. Methods: A cross-sectional study of 2,173 Scottish adolescents (age 12/13 years) using…

Self-compassion and fear of self-compassion interact to predict response to eating disorders treatment: a preliminary investigation.
Gilbert (2005) proposed that the capacity for self-compassion is integral to overcoming shame and psychopathology. We tested this model among 74 individuals with an eating disorder admitted to specialized treatment. Participants completed measures assessing self-compassion, fear of self-compassion, shame, and eating disorder symptoms at admission and every 3 weeks during treatment. At baseline, lower self-compassion and higher fear of self-compassion were associated with more shame and eating disorder pathology. Multilevel modeling also revealed that patients with combinations of low self-compassion and high fear of self-compassion at baseline had significantly poorer treatment responses, showing no significant change in shame or eating disorder symptoms over 12 weeks. Results highlight a new subset of treatment-resistant eating disorder patients.

Discriminative inhibitory control of cocaine seeking involves the prelimbic prefrontal cortex.
Background: Recent neuroimaging studies have shown that people with cocaine addiction retain some degree of control over drug craving that correlates with neural activity in the lateral prefrontal cortex (PFC). Here, we report similar findings in a rat model of inhibitory control of cocaine seeking. Methods: Rats actively responding for cocaine were trained to stop responding when presented with a discriminative stimulus that signaled lack of reinforcement. Rats were then tested for inhibitory control of cocaine seeking in novel behavioral contexts and in circumstances when cocaine seeking is particularly intense (e.g., following drug priming). The role of neuronal activity in different subregions of the PFC was assessed using local pharmacologic inactivation and c-Fos immunohistochemistry. Results: Rats progressively acquired the ability to stop cocaine seeking, even during drug intoxic…

Differential effectiveness of tianeptine, clonidine and amitriptyline in blocking traumatic memory expression, anxiety and hypertension in an animal model of PTSD.
Individuals exposed to life-threatening trauma are at risk for developing post-traumatic stress disorder (PTSD), a debilitating condition that involves persistent anxiety, intrusive memories and several physiological disturbances. Current pharmacotherapies for PTSD manage only a subset of these symptoms and typically have adverse side effects which limit their overall effectiveness. We evaluated the effectiveness of three different pharmacological agents to ameliorate a broad range of PTSD-like symptoms in our established predator-based animal model of PTSD. Adult male Sprague-Dawley rats were given 1-h cat exposures on two occasions that were separated by 10 days, in conjunction with chronic social instability. Beginning 24 h after the first cat exposure, rats received daily injections of amitriptyline, clonidine, tianeptine or vehicle. Three weeks after the second cat exposure, all rat…

From early sensory specialization to later perceptual generalization: dynamic temporal progression in perceiving individual threats.
Threat evokes a variety of negative emotions such as fear, anger, and disgust. Whereas they elicit distinct and even opposite facial, sensory, and autonomic reflexes, threat-related emotions often converge in the actions they prompt (e.g., negative evaluation and avoidance). Here, we tested a unifying hypothesis that threat processing initially involves specialized encoding of individual subtypes to support discrete reflexive operations that later gives way to generalized elaborate analysis to facilitate convergent defensive behavior. Combining event-related potentials (ERPs) and a defensive context in human subjects, we compared temporal courses of perceptual analysis of two threat subtypes-fear and disgust. Indeed, fear enhanced and disgust suppressed early (115 ms) response in visual cortex, accentuating specialized sensory encoding of threat subtypes in accordance with the opposite b…

Corticolimbic brain reactivity to social signals of threat before and after sertraline treatment in generalized social phobia.
Background: Generalized social phobia (gSP), also known as generalized social anxiety disorder, is characterized by excessive fear of scrutiny by others and pervasive avoidance of social interactions. Pathophysiologic models of gSP implicate exaggerated reactivity of the amygdala and insula in response to social evaluative threat, making them plausible targets for treatment. Although selective serotonin reuptake inhibitor (SSRI) treatment is known to be an effective treatment, little is known about the mechanism through which these agents exert their anxiolytic effects at a brain level in gSP. Methods: We acquired functional magnetic resonance imaging data of brain response to social signals of threat (fearful/angry faces) in 21 gSP patients before and after they completed 12 weeks of open-label treatment with the SSRI sertraline. For comparison, 19 healthy control (HC) subjects also und…

Psychological morbidity and stress but not social factors influence level of fear of cancer recurrence in young women with early breast cancer: results of a cross-sectional study.
Background: Fear of cancer recurrence (FCR) is a common problem amongst survivors. Past research has shown that young women with breast cancer are particularly vulnerable to FCR, yet few previous studies have specifically examined FCR in this subgroup. Aims: The aim of the study is to explore the relationship between FCR, psychological morbidity and social factors. A secondary aim was to explore the relationship between clinical levels of FCR and generalised anxiety disorder (GAD) and hypochondriasis. Method: Two hundred eighteen breast cancer survivors (aged 18-45 years at diagnosis) diagnosed at least 1 year prior were recruited through seven metropolitan oncology clinics and two breast cancer consumer groups. Participants completed a web-based questionnaire, which assessed FCR, psychological functioning, generalised anxiety, hypochondriasis and items exploring past cancer-related expe…

Social appearance anxiety, perfectionism, and fear of negative evaluation: distinct or shared risk factors for social anxiety and eating disorders?
Social anxiety and eating disorders are highly comorbid. Social appearance anxiety (i.e., fear of negative evaluation of one's appearance), general fear of negative evaluation, and perfectionism have each been proposed as risk factors for both social anxiety disorder and the eating disorders. However, no research to date has examined all three factors simultaneously. Using structural equation modeling in two diverse samples (N=236; N=136) we tested a model in which each of these risk factors were uniquely associated with social anxiety and eating disorder symptoms. We found support for social appearance anxiety as a shared risk factor between social anxiety and eating disorder symptoms, whereas fear of negative evaluation was a risk factor only for social anxiety symptoms. Despite significant zero-order relationships, two facets of perfectionism (high standards and maladaptive perfection…

Disclosure of HIV status between parents and children in Uganda in the context of greater access to treatment.
While disclosure of HIV sero-status is encouraged in the management of the HIV and AIDS epidemic, it remains a challenge, especially among family members. This article examines the moral dilemmas and pragmatic incentives surrounding disclosure of HIV status in contemporary Uganda. Our findings are based on 12 in-depth interviews, 2 focus-group discussions, 6 key informant interviews with AIDS activists, and open-ended responses derived from 148 HIV-positive persons in a quantitative survey. The study was conducted in 2008-2009 in Kampala, Mpigi, and Soroti districts in Uganda. We found both parents and adult children facing dilemmas in disclosure, whether it was parents revealing their own HIV status to their children or the status of their perinatally infected children, or young people infected through sexual intercourse telling their parents. For both groups, there is fear of blame, st…

Interactions between transient and sustained neural signals support the generation and regulation of anxious emotion.
Anxious emotion can manifest on brief (threat response) and/or persistent (chronic apprehension and arousal) timescales, and prior work has suggested that these signals are supported by separable neural circuitries. This fMRI study utilized a mixed block-event-related emotional provocation paradigm in 55 healthy participants to simultaneously measure brief and persistent anxious emotional responses, testing the specificity of, and interactions between, these potentially distinct systems. Results indicated that components of emotional processing networks were uniquely sensitive to transient and sustained anxious emotion. Whereas the amygdala and midbrain showed only transient responses, the ventral basal forebrain and anterior insula showed sustained activity during extended emotional contexts that tracked positively with task-evoked anxiety. States of lesser anxiety were associated with …
