وَضَرَبَ ٱللَّهُ مَثَلࣰ ا قَرۡيَةࣰ كَانَتۡ ءَامِنَةࣰ مُّطۡمَئِنَّةࣰ يَأۡتِيهَا رِزۡقُهَا رَغَدࣰ ا مِّن كُلِّ مَكَانࣲ فَكَفَرَتۡ بِأَنۡعُمِ ٱللَّهِ فَأَذَٰقَهَا ٱللَّهُ لِبَاسَ ٱلۡجُوعِ وَٱلۡخَوۡفِ بِمَا كَانُواْ يَصۡنَعُونَ
God presents the example of a town that was secure and at ease, with provisions coming to it abundantly from all places. Then it became ungrateful for God’s blessings, so God afflicted it with the garment of famine and fear, for what its people had done
Qur'ān 2:155English sense: fear | Arabic sense: الخوف, خوف

who begrudge you [believers] any help. When fear comes, you [Prophet] see them looking at you with eyes rolling like someone in their death throes; when fear has passed, they attack you with sharp tongues and begrudge you any good. Such men do not believe, and God brings their deeds to nothing- that is all too easy for God

Whenever news of any matter comes to them, whether concerning peace or war, they spread it about; if they referred it to the Messenger and those in authority among them, those seeking its meaning would have found it out from them. If it were not for God’s bounty and mercy towards you, you would almost all have followed Satan

And We will indeed try you with something of fear and hunger, and decrease of wealth, souls, and fruits; and give good news to the patient. The custom of the Lord is that whenever He threatens the servant and shows harshness in a verse, then, right after that or before it, He caresses the servant and gives him hope. Thus in this verse He breaks the servant by mentioning those harsh things and varieties of trial. Then He gives good news, He caresses, and He says, “and give good news to the patient.” And, at the beginning of these verses He says, “Surely God is with the patient” [2:153]. Glory be to Him! How gentle and how merciful He is to His servants! And We will indeed try you. He says, “We will test you, sometimes with fear, sometimes with dread, sometimes with poverty, sometimes with hunger, sometimes with outward affliction, sometimes with inward sorrow.” The outward trial and evide

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.

And Allah gives the example of a township (Makkah), it was secure and peaceful: its provision coming to it in abundance from every place, but it (its people) denied the favors of Allah. So Allah made it taste extreme hunger (famine) and fear, because of what they did (112)There has come to them a Messenger from among themselves, but they denied him, so the torment seized them while they were wrongdoers (113)
The Example of Makkah
This example refers to the people of Makkah, which had been secure, peaceful and stable, a secure sanctuary while men were being snatched away from everywhere outside of it. Whoever entered Makkah, he was safe, and he had no need to fear, as Allah said:

Two is more valid than one: Examining the factor structure of the Self-Compassion Scale (SCS).
The Self-Compassion Scale (SCS; Neff, 2003a) is the most widely used measure of self-compassion. Self-compassion, as measured by the SCS, is robustly linked to psychological health (Macbeth & Gumley, 2012; Zessin, Dickhaüser, & Garbade, 2015). The SCS is currently understood as exhibiting a higher-order structure comprised of 6 first-order factors and 1 second-order general self-compassion factor. Recently, some researchers have questioned the internal validity of this 1-factor conceptualization, and posit that the SCS may instead be comprised of 2 general factors-self-compassion and self-coldness. The current paper provides an in-depth examination of the internal structure of the SCS using oblique, higher-order, and bifactor structural models in a sample of 1,115 college students. The bifactor model comprised of 2 general factors-self-compassion and self-coldness-and 6 specific factors …

Body image and psychological distress in nipple-sparing mastectomy: the roles of self-compassion and appearance investment.
Objective: Women with breast cancer face threats to body image following surgery. Nipple-sparing mastectomy with immediate breast reconstruction (NSM + IBR) may minimise body image disturbance as this preserves the woman's skin and areola complex. We assessed levels of body image disturbance and psychological distress in women undergoing NSM + IBR. To further understand the body image-distress relationship, we investigated the potential moderating effect of self-compassion and appearance investment on this relationship.
Methods: Women diagnosed with breast cancer (N = 75) who had undergone NSM + IBR completed online questionnaires including the Body Image Scale, general (Depression, Anxiety and Stress Scales) and cancer-specific (Impact of Event Scale) psychological distress and Self-Compassion Scale and Appearance Schemas Inventory - Revised.

When Emotional Pain Becomes Physical: Adverse Childhood Experiences, Pain, and the Role of Mood and Anxiety Disorders.
Objective: We examined the association between retrospective reports of adverse childhood experiences (ACEs) and painful medical conditions. We also examined the mediating and moderating roles of mood and anxiety disorders in the ACEs-painful medical conditions relationship.
Method: Ten-year longitudinal data were obtained from the National Comorbidity Surveys (NCS-1, NCS-2; N = 5001). The NCS-1 obtained reports of ACEs, current health conditions, current pain severity, and mood and anxiety disorders. The NCS-2 assessed for painful medical conditions (e.g., arthritis/rheumatism, chronic back/neck problems, severe headaches, other chronic pain).
Results: Specific ACEs (e.g., verbal and sexual abuse, parental psychopathology, and early parental loss) were associated with the painful medical conditions. Baseline measures of depression, bipolar disorder, and posttraumatic stress disorder wer…

Imbalance between TNFα and progranulin contributes to memory impairment and anxiety in sleep-deprived mice.
Sleep disorder is becoming a widespread problem in current society, and is associated with impaired cognition and emotional disorders. Progranulin (PGRN), also known as granulin epithelin precursor, promotes neurite outgrowth and cell survival, and is encoded by the GRN gene. It is a tumor necrosis factor α receptor (TNFR) ligand which is implicated in many central nervous system diseases. However, the role PGRN in sleep disorder remains unclear. In the present study, we found that sleep deprivation (S-DEP) impaired the memory and produced thigmotaxis/anxiety-like behaviors in mice. S-DEP increased the levels of TNFα but decreased PGRN levels in the hippocampus. The intracerebroventricular (ICV) injection of PGRN or intraperitoneal injection of TNFα synthesis blocker thalidomide (25 mg/kg), prevented the memory impairment and anxiety behaviors induced by S-DEP. PGRN treatment also restor…

Neural basis of impaired safety signaling in Obsessive Compulsive Disorder.
The ability to assign safety to stimuli in the environment is integral to everyday functioning. A key brain region for this evaluation is the ventromedial prefrontal cortex (vmPFC). To investigate the importance of vmPFC safety signaling, we used neuroimaging of Pavlovian fear reversal, a paradigm that involves flexible updating when the contingencies for a threatening (CS+) and safe (CS-) stimulus reverse, in a prototypical disorder of inflexible behavior influenced by anxiety, Obsessive Compulsive Disorder (OCD). Skin conductance responses in OCD patients (n = 43) failed to differentiate during reversal compared with healthy controls (n = 35), although significant differentiation did occur during early conditioning and amygdala BOLD signaling was unaffected in these patients. Increased vmPFC activation (for CS+ > CS-) during early conditioning predicted the degree of generalization in …

Risk Factors for Internet Gaming Disorder: Psychological Factors and Internet Gaming Characteristics.
Background: Understanding the risk factors associated with Internet gaming disorder (IGD) is important to predict and diagnose the condition. The purpose of this study is to identify risk factors that predict IGD based on psychological factors and Internet gaming characteristics; Methods: Online surveys were conducted between 26 November and 26 December 2014. There were 3568 Korean Internet game users among a total of 5003 respondents. We identified 481 IGD gamers and 3087 normal Internet gamers, based on Diagnostic and Statistical Manual for Mental Disorders (DSM-5) criteria. Logistic regression analysis was applied to identify significant risk factors for IGD; Results: The following eight risk factors were found to be significantly associated with IGD: functional and dysfunctional impulsivity (odds ratio: 1.138), belief self-control (1.034), anxiety (1.086), pursuit of desired appetiti…

Targeting the Microbiota-Gut-Brain Axis: Prebiotics Have Anxiolytic and Antidepressant-like Effects and Reverse the Impact of Chronic Stress in Mice.
Background: The realization that the microbiota-gut-brain axis plays a critical role in health and disease, including neuropsychiatric disorders, is rapidly advancing. Nurturing a beneficial gut microbiome with prebiotics, such as fructo-oligosaccharides (FOS) and galacto-oligosaccharides (GOS), is an appealing but underinvestigated microbiota manipulation. Here we tested whether chronic prebiotic treatment modifies behavior across domains relevant to anxiety, depression, cognition, stress response, and social behavior.
Methods: C57BL/6J male mice were administered FOS, GOS, or a combination of FOS+GOS for 3 weeks prior to testing. Plasma corticosterone, microbiota composition, and cecal short-chain fatty acids were measured. In addition, FOS+GOS- or water-treated mice were also exposed to chronic psychosocial stress, and behavior, immune, and microbiota parameters were assessed.

Neural correlates of an attentional bias to health-threatening stimuli in individuals with pathological health anxiety.
Background: An attentional bias to health-threat stimuli is assumed to represent the primary pathogenetic factor for the development and maintenance of pathological health anxiety (PHA; formerly termed "hypochondriasis"). However, little is known about the neural basis of this attentional bias in individuals with PHA.
Methods: A group of patients with PHA, a group of depressed patients and a healthy control group completed an emotional Stroop task with health-threat (body symptom and illness) words and neutral control words while undergoing functional MRI.
Results: We included 33 patients with PHA, 28 depressed patients and 31 controls in our analyses. As reflected in reaction times, patients with PHA showed a significantly stronger attentional bias to health-threat words than both control groups. In addition, patients with PHA showed increased amygdala and rostral anterior cingulate cor…

Altered functional connectivity of interoception in illness anxiety disorder.
Interoception collects all information coming from the body and is sustained by several brain areas such as insula and cingulate cortex. Here, we used resting-state functional magnetic resonance imaging to investigate functional connectivity (FC) of networks implied in interoception in patients with Illness anxiety disorders (IADs). We observed significantly reduced FC between the left extrastriate body area (EBA) and the paracentral lobule compared to healthy controls. Moreover, the correlation analysis between behavioural questionnaires and ROI to ROI FC showed that higher levels of illness anxiety were related to hyper-connectivity between EBA and amygdala and hippocampus. Scores on a questionnaire for interoceptive awareness were significantly correlated with higher FC between right hippocampus and nucleus accumbens bilaterally, and with higher connectivity between left anterior cing…

Mood instability is a core clinical feature of affective and psychotic disorders. In keeping with the Research Domain Criteria approach, it may be a useful construct for identifying biology that cuts across psychiatric categories. We aimed to investigate the biological validity of a simple measure of mood instability and evaluate its genetic relationship with several psychiatric disorders, including major depressive disorder (MDD), bipolar disorder (BD), schizophrenia, attention deficit hyperactivity disorder (ADHD), anxiety disorder and post-traumatic stress disorder (PTSD). We conducted a genome-wide association study (GWAS) of mood instability in 53,525 cases and 60,443 controls from UK Biobank, identifying four independently associated loci (on chromosomes 8, 9, 14 and 18), and a common single-nucleotide polymorphism (SNP)-based heritability estimate of ~8%.

Studies suggest that heightened peripheral inflammation contributes to the pathogenesis of major depressive disorder. We investigated the effect of chronic social defeat stress, a mouse model of depression, on blood-brain barrier (BBB) permeability and infiltration of peripheral immune signals. We found reduced expression of the endothelial cell tight junction protein claudin-5 (Cldn5) and abnormal blood vessel morphology in nucleus accumbens (NAc) of stress-susceptible but not resilient mice. CLDN5 expression was also decreased in NAc of depressed patients. Cldn5 downregulation was sufficient to induce depression-like behaviors following subthreshold social stress whereas chronic antidepressant treatment rescued Cldn5 loss and promoted resilience. Reduced BBB integrity in NAc of stress-susceptible or mice injected with adeno-associated virus expressing shRNA against Cldn5 caused infiltr…

Prenatal stress affects placental cytokines and neurotrophins, commensal microbes, and anxiety-like behavior in adult female offspring.
Recent studies demonstrate that exposure to stress changes the composition of the intestinal microbiota, which is associated with development of stress-induced changes to social behavior, anxiety, and depression. Stress during pregnancy has also been related to the emergence of these disorders; whether commensal microbes are part of a maternal intrauterine environment during prenatal stress is not known. Here, we demonstrate that microbiome changes are manifested in the mother, and also found in female offspring in adulthood, with a correlation between stressed mothers and female offspring. Alterations in the microbiome have been shown to alter immune responses, thus we examined cytokines in utero. IL-1β was increased in placenta and fetal brain from offspring exposed to the prenatal stressor. Because IL-1β has been shown to prevent induction of brain derived neurotrophic factor (BDNF), …

Prediction of pre-exam state anxiety from ruminative disposition: The mediating role of impaired attentional disengagement from negative information.
Rumination is a maladaptive form of repetitive thinking that enhances stress responses, and heightened disposition to engage in rumination may contribute to the onset and persistence of stress-related symptoms. However, the cognitive mechanisms through which ruminative disposition influences stress reactivity are not yet fully understood. This study investigated the hypothesis that the impact of ruminative disposition on stress reactivity is carried by an attentional bias reflecting impaired attentional disengagement from negative information. We examined the capacity of a measure of ruminative disposition to predict both attentional biases to negative exam-related information, and state anxiety, in students approaching a mid-term exam. As expected, ruminative disposition predicted state anxiety, over and above the level predicted by trait anxiety. Ruminative disposition also predicted b…

Anti-gay, or homonegative, prejudice is generally considered harmful to the wellbeing of sexual minority individuals. However, the origins or nature of such prejudice may vary. Despite a sizable body of literature suggesting homonegative prejudice is frequently religious-based, the psychological impact of exposure to religious anti-gay prejudice remains largely undetermined. Addressing this research gap, the authors examined whether opposition to same-sex sexuality on religious grounds predicted detrimental outcomes among same- and both-sex attracted individuals, as well as their heterosexual counterparts. A nationwide U.S. sample of 1600 individuals-recruited using contemporary online crowd-sourcing techniques designed to limit selection bias-completed a novel inventory assessing interpersonal exposure to religious (as well as nonreligious) homonegative disapproval. Outcome variables as…

Kumar S, Tansley-Hancock O, Sedley W, Winston JS, Callaghan MF, Allen M, Cope TE, Gander PE, Bamiou DE, Griffiths TD (2017)MEDLINE-indexed journal, not yet read by usCurrent biology : CB146 citations The Brain Basis for Misophonia.
Misophonia is an affective sound-processing disorder characterized by the experience of strong negative emotions (anger and anxiety) in response to everyday sounds, such as those generated by other people eating, drinking, chewing, and breathing [1-8]. The commonplace nature of these sounds (often referred to as "trigger sounds") makes misophonia a devastating disorder for sufferers and their families, and yet nothing is known about the underlying mechanism. Using functional and structural MRI coupled with physiological measurements, we demonstrate that misophonic subjects show specific trigger-sound-related responses in brain and body. Specifically, fMRI showed that in misophonic subjects, trigger sounds elicit greatly exaggerated blood-oxygen-level-dependent (BOLD) responses in the anterior insular cortex (AIC), a core hub of the "salience network" that is critical for perception of in…

Gender differences in factors associated with smartphone addiction: a cross-sectional study among medical college students.
Background: Smartphones are becoming increasingly indispensable in everyday life for most undergraduates in China, and this has been associated with problematic use or addiction. The aim of the current study was to investigate the prevalence of smartphone addiction and the associated factors in male and female undergraduates.
Methods: This cross-sectional study was conducted in 2016 and included 1441 undergraduate students at Wannan Medical College, China. The Smartphone Addiction Scale short version (SAS-SV) was used to assess smartphone addiction among the students, using accepted cut-offs. Participants' demographic, smartphone usage, and psycho-behavioral data were collected. Multivariate logistic regression models were used to seek associations between smartphone addiction and independent variables among the males and females, separately.
Results: The prevalence of smartphone addicti…
