Psoriasis is a chronic, inflammatory scaling dermatosis. The marked visible appearance of the lesions have a negative impact on body image that leads to decreased self-esteem, hence seriously compromising the patient's quality of life. The clinical picture critically affects the social well-being of the patient since the disease is commonly misunderstood and feared by the social environment as being contagious. The patient feels stigmatized and this further intensifies their lack of self-confidence and self-esteem...

Anxiety disorders are the most common type of mental disorder during adolescence, which is at least partly due to the resistance to extinction exhibited at this age. The dopaminergic system is known to be dysregulated during adolescence; therefore, we aimed to facilitate extinction in adolescent rats using the dopamine receptor 2 partial agonist aripiprazole (Abilify™), and examine the behavioral and neural outcomes. Adolescent rats were conditioned to fear a tone. The next day, rats received extinction 30 min after a systemic injection of either 5 mg/kg aripiprazole or vehicle, and then were tested the following day...

Since the nineteenth century several clinical features have been observed in common between migraine and epilepsy (such as episodic attacks, triggering factors, presence of aura, frequent familiarity), but only in recent years researchers have really engaged in finding a common pathogenic mechanism. From studies of disease incidence, we understand how either migraine among patients with epilepsy or epilepsy among migraine patients are more frequent than in the general population. This association may result from a direct causality, by the same environmental risk factors and/or by a common genetic susceptibility...

The prevalence of psychological distress, especially depressive and anxiety disorders, is higher in epilepsy than in other chronic health conditions. These comorbid conditions contribute even more than epileptic seizures themselves to impaired quality of life in patients with epilepsy (PWE). The link between these comorbidities and epilepsy appears to have a neurobiological basis, which is at least partly mediated by stress through psychological and pathophysiological pathways. The impact of stress in PWE is also particularly important because it is the most frequently reported seizure trigger...

PHF8 is a histone demethylase with specificity for repressive modifications. While mutations of PHF8 have been associated with cognitive defects and cleft lip/palate, its role in mammalian development and physiology remains unexplored. Here, we have generated a Phf8 knockout allele in mice to examine the consequences of Phf8 loss for development and behaviour. Phf8 deficient mice neither display obvious developmental defects nor signs of cognitive impairment. However, we report a striking resiliency to stress-induced anxiety- and depression-like behaviour on loss of Phf8...

BACKGROUND: The present study was conducted to examine the hypothesis based on our previous studies, that the multiple diagnoses of comorbid anxiety disorders (ADs) and higher interpersonal sensitivity predict treatment-resistant depression (TRD). METHODS: The participants were 199 consecutive outpatients with major depressive disorder (MDD), who were comprehensively diagnosed using the Mini International Neuropsychiatric Interview (MINI). TRD was defined as the failure to achieve remission with two or more adequate antidepressant trials...

Elevated oxidative stress is known to play an important role in development of depression and cognitive dysfunction. To date, thioredoxin (TRX), an antioxidant protein, has been investigated as a marker for psychiatric disorders such as schizophrenia, bipolar disorder and autism but its relationship with depression is yet to be unknown. The aim of this study is to detect the TRX levels in patients with treatment-resistant depression (TRD), analyse the effect of rTMS (repetitive transcranial magnetic stimulation) application on TRX levels and display the relationship of TRX with cognitive areas...

The N-methyl-D-aspartate receptor antagonist ketamine has rapid onset activity in treatment-resistant depression, post-traumatic stress disorder and obsessive compulsive disorder. Due to similarities in brain network activity in depression and anxiety disorders, we hypothesized that ketamine might also be active in other refractory anxiety disorders. We evaluated the efficacy and safety of ketamine in 12 patients with refractory generalized anxiety disorder and/or social anxiety disorder who were not currently depressed, using an ascending single dose study design (0...

There is growing concern worldwide for macrolide resistance in M. genitalium following liberal use of 1 g azithromycin to treat non-gonococcal urethritis and confirmed C. trachomatis infection. Moxifloxacin is the second-line treatment for M. genitalium and still has excellent efficacy against it. However, recent reports indicating that quinolone resistance is more prevalent than previously thought are worrying. Routine testing of symptomatic men and women for M. genitalium is not currently recommended in BASHH guidelines, and attempts to implement such testing have been hampered by a lack of commercially available assays...

The insula is now regarded as a potential site of epileptogenesis in drug-resistant epilepsy, and the advent of microsurgical techniques has allowed insular cortectomy to become a treatment of choice when the insular cortex is involved in the seizure focus. However, considering the evidence of an insular role in socio-emotional processing, it remains unknown whether these cortical resections disturb personality and social behavior as experienced in daily life. We examined such changes in a group of patients (n=19) who underwent epilepsy surgery involving partial or complete resection of the insula, and compared them to a group of patients who underwent standard temporal lobe epilepsy (TLE) surgery (n=19) as a lesion-control group...

Obsessive-compulsive (OC) disorder is a disabling disorder resulting in tremendous individual and social burden. It has a large overlap with depression and anxiety disorders and shows treatment resistance in a relevant proportion of patients. Since a couple of years, different noninvasive brain stimulation methods have been investigated to improve OC symptoms. The application of transcranial direct current stimulation (tDCS) has shown inconsistent results which can probably be attributed to a lack in randomized controlled trials with adequate sample size...

In anxiety, maladaptive avoidance behavior provides for near-perfect controllability of potential threat. There has been little laboratory-based treatment research conducted on controllability as a contributing factor in the transition from adaptive to maladaptive avoidance. Here, we investigated for the first time whether partial reinforcement rate, or the reliability of avoidance at controlling or preventing contact with an aversive event, influences subsequent extinction of avoidance in humans. Five groups of participants were exposed to different partial reinforcement rates where avoidance cancelled upcoming shock on 100%, 75%, 50%, 25% or 0% of trials...

BACKGROUND: Patients with terminal chronic kidney disease (CKDT) requiring renal replacement therapies (RRT) undergo important changes in living habits and frequently need caregiving. These patients and their caregivers are risk groups for the development of physical and psychological symptoms. This study aimed to evaluate the prevalence of anxiety, depression, stress, fatigue, social support, and quality of life in patients with CKD and their caregivers. METHOD: This cross sectional study was conducted with 21 patients and their caregivers, from January to September 2015...

OBJECTIVE: Protein tyrosine phosphatase 1B (PTP1B) has been extensively implicated in the regulation of body weight, food intake, and energy expenditure. The role of PTP1B appears to be cell and brain region dependent. RESULTS: Herein, we demonstrated that chronic high-fat feeding enhanced PTP1B expression in the central nucleus of the amygdala (CeA) of rats compared to rats on chow. Knocking down PTP1B with oligonucleotide antisense (ASO) decreased its expression and was sufficient to improve the anorexigenic effect of insulin through IR/Akt signaling in the CeA...

Chronic musculoskeletal pain (CMP) refers to ongoing pain felt in the bones, joints and tissues of the body that persists longer than 3 months. For these conditions, it is widely accepted that secondary pathologies or the consequences of persistent pain, including fear of movement, pain catastrophizing, anxiety and nervous system sensitization appear to be the main contributors to pain and disability. While exercise is a primary treatment modality for CMP, the intent is often to improve physical function with less attention to secondary pathologies...

A neurochemical target at which cannabinoids interact to have global effects on behavior is brain noradrenergic circuitry. Acute and repeated administration of a cannabinoid receptor synthetic agonist is capable of increasing multiple indices of noradrenergic activity. This includes cannabinoid-induced 1) increases in norepinephrine (NE) release in the medial prefrontal cortex (mPFC); 2) desensitization of cortical α2-adrenoceptor-mediated effects; 3) activation of c-Fos in brainstem locus coeruleus (LC) noradrenergic neurons; and 4) increases in anxiety-like behaviors...
