Minerva pediatrica. 2020;(5):424-432
Abstract
Eosinophilic esophagitis (EoE) is a chronic disease characterized by symptoms related to esophageal dysfunction and eosinophil-predominant inflammation (≥15 eosinophils/high power field). In the last ten years, several epidemiological studies showed a significant increase in the incidence and prevalence of EoE, especially in children in Western Countries. Although EoE often presents with gastrointestinal symptoms, adults and children may develop extraintestinal symptoms and behavioral issues. Also, the chronic nature of the disease, long-term therapies, and strict follow-up may impair the quality of life of patients and their family. This review summarizes current knowledge on the behavioral and psychosocial issues and quality of life of children and adolescents with EoE and their caregivers.

Abstract
PURPOSE OF REVIEW Despite a call for better understanding of the role of environmental pollutant influences on mental health and the tremendous public health burden of mental health, this issue receives far less attention than many other effects of pollutants. Here we summarize the body of literature on non-occupational environmental pollutant exposures and adult depression, anxiety, and suicide-in PubMed, Embase, Web of Science, and PsychINFO through the end of year 2018. RECENT FINDINGS One hundred twelve articles met our criteria for further review. Of these, we found 88 articles on depression, 33 on anxiety, and 22 on suicide (31 articles covered multiple outcomes). The earliest article was published in 1976, and the most frequent exposure of interest was air pollution (n = 33), followed by secondhand smoke (n = 20), metals (n = 18), noise (n = 17), and pesticides (n = 10). Other exposures studied less frequently included radiation, magnetic fields, persistent organic pollutants (POPs), volatile organic compounds, solvents, and reactive sulfur compounds. The current literature, although limited, clearly suggests many kinds of environmental exposures may be risk factors for depression, anxiety, and suicide. For several pollutants, important limitations exist with many of the studies. Gaps in the body of research include a need for more longitudinal, life-course studies, studies that can measure cumulative exposures as well as shorter-term exposures, studies that reduce the possibility of reverse causation, and mechanistic studies focused on neurotoxic exposures.

Abstract
PURPOSE This study evaluated the effects of coping skills training (CST) on symptoms of depression and anxiety in cancer patients, and investigated moderators of the effects. METHODS Overall effects and intervention-related moderators were studied in meta-analyses of pooled aggregate data from 38 randomized controlled trials (RCTs). Patient-related moderators were examined using linear mixed-effect models with interaction tests on pooled individual patient data (n = 1953) from 15 of the RCTs. RESULTS CST had a statistically significant but small effect on depression (g = -0.31,95% confidence interval (CI) = -0.40;-0.22) and anxiety (g = -0.32,95%CI = -0.41;-0.24) symptoms. Effects on depression symptoms were significantly larger for interventions delivered face-to-face (p = .003), led by a psychologist (p = .02) and targeted to patients with psychological distress (p = .002). Significantly larger reductions in anxiety symptoms were found in younger patients (pinteraction < 0.025), with the largest reductions in patients <50 years (β = -0.31,95%CI = -0.44;-0.18) and no significant effects in patients ≥70 years. Effects of CST on depression (β = -0.16,95%CI = -0.25;-0.07) and anxiety (β = -0.24,95%CI = -0.33;-0.14) symptoms were significant in patients who received chemotherapy but not in patients who did not (pinteraction < 0.05). CONCLUSIONS CST significantly reduced symptoms of depression and anxiety in cancer patients, and particularly when delivered face-to-face, provided by a psychologist, targeted to patients with psychological distress, and given to patients who were younger and received chemotherapy.

Relationship between the gut microbiome and brain function.
Mohajeri, MH, La Fata, G, Steinert, RE, Weber, P
Nutrition reviews. 2018;(7):481-496
Abstract
It has become increasingly evident in recent years that the gut microbiome and the brain communicate in a bidirectional manner, with each possibly affecting the other's functions. Substantial research has aimed to understand the mechanisms of this interaction and to outline strategies for preventing or treating nervous system-related disturbances. This review explores the evidence demonstrating how the gut microbiome may affect brain function in adults, thereby having an impact on stress, anxiety, depression, and cognition. In vitro, in vivo, and human studies reporting an association between a change in the gut microbiome and functional changes in the brain are highlighted, as are studies outlining the mechanisms by which the brain affects the microbiome and the gastrointestinal tract. Possible modes of action to explain how the gut microbiome and the brain functionally affect each other are proposed. Supplemental probiotics to combat brain-related dysfunction offer a promising approach, provided future research elucidates their mode of action and possible side effects. Further studies are warranted to establish how pre- and probiotic interventions may help to balance brain function in healthy and diseased individuals.

Saffron in the treatment of depression, anxiety and other mental disorders: Current evidence and potential mechanisms of action.
Shafiee, M, Arekhi, S, Omranzadeh, A, Sahebkar, A
Journal of affective disorders. 2018;:330-337
Abstract
BACKGROUND Depression and anxiety are two common mental health problems with high economic and social costs. Currently, a number of treatments are available for patients with depression and anxiety disorders such as psychotherapy, electroconvulsive therapy and antidepressant drugs. Due to safety concerns, adverse effects, limited efficacy and low tolerability associated with many antidepressant and anti-anxiety medications, identification of novel agents with less toxicity and more favorable outcome is warranted. METHODS The current article provides a non-systematic review of the available in vitro, in vivo and clinical evidence on the efficacy, safety and mechanisms of action of saffron and its active ingredients in the treatment of anxiety, depression and other mental disorders. RESULTS Several interesting data have been reported about the antidepressant and anti-anxiety properties of saffron, the dried stigmas of Crocus sativus L., in several preclinical and clinical studies. In particular, a number of clinical trials demonstrated that saffron and its active constituents possess antidepressant properties similar to those of current antidepressant medications such as fluoxetine, imipramine and citalopram, but with fewer reported side effects. CONCLUSION Saffron may exert antidepressant effects and represents an efficacious and safe treatment.

Abstract
BACKGROUND Attachment has been implicated in the development of social anxiety. Our aim was to synthesise the extant literature exploring the role of adult attachment in these disorders. METHOD Search terms relating to social anxiety and attachment were entered into MEDLINE, PsycINFO and Web of Science. Risk of bias of included studies was assessed using and adapted version of the Agency for Healthcare Research and Quality assessment tool. Eligible studies employed validated social anxiety and attachment assessments in adult clinical and analogue samples. The review included cross sectional, interventional and longitudinal research. RESULTS Of the 30 identified studies, 28 showed a positive association between attachment insecurity and social anxiety. This association was particularly strong when considering attachment anxiety. Cognitive variables and evolutionary behaviours were identified as potential mediators, concordant with psychological theory. LIMITATIONS Due to a lack of longitudinal research, the direction of effect between attachment and social anxiety variables could not be inferred. There was substantial heterogeneity in the way that attachment was conceptualised and assessed across studies. CONCLUSIONS The literature indicates that attachment style is associated with social anxiety. Clinicians may wish to consider attachment theory when working clinically with this population. In the future, it may be useful to target the processes that mediate the relationship between attachment and social anxiety.

Prenatal anxiety effects: A review.
Field, T
Infant behavior & development. 2017;:120-128
Abstract
This review is based on literature on prenatal anxiety effects that was found on Pubmed and PsycINFO for the years 2010-2016. Prenatal anxiety is thought to have distinct features, although it has been measured both by specific prenatal anxiety symptoms as well as by standardized anxiety scales. Its prevalence has ranged from 21 to 25% and it has been predicted by a number of pregnancy - related variables such as unintended pregnancy, demographic variables such as low acculturation and income and psychosocial factors including pessimism and partner tension. Prenatal anxiety effects on pregnancy include increased cortisol levels, pro-inflammatory cytokines, obstetric problems and cesarean section. Effects on the neonate include lower gestational age, prematurity, less insulin-like growth factor in cord blood, less exclusive breast-feeding and less self-regulation during the heelstick procedure. Prenatal anxiety effects continue into infancy and childhood both on physiological development and emotional/mental development. Among the physiological effects are lower vagal activity across the first two years, and lower immunity, more illnesses and reduced gray matter in childhood. Prenatal anxiety effects on emotional/mental development include greater negative emotionality and in infants, lower mental development scores and internalizing problems. Anxiety disorders occur during childhood and elevated cortisol and internalizing behaviors occur during adolescence. Interventions for prenatal anxiety are virtually nonexistent, although stroking (massaging) the infant has moderated the pregnancy - specific anxiety effects on internalizing behaviors in the offspring. The limitations of this literature include the homogeneity of samples, the frequent use of anxiety measures that are not specific to pregnancy, and the reliance on self-report. Nonetheless, the literature highlights the negative, long-term effects of prenatal anxiety and the need for screening and early interventions.

Cannabidiol in medical marijuana: Research vistas and potential opportunities.
Rong, C, Lee, Y, Carmona, NE, Cha, DS, Ragguett, RM, Rosenblat, JD, Mansur, RB, Ho, RC, McIntyre, RS
Pharmacological research. 2017;:213-218
Abstract
The high and increasing prevalence of medical marijuana consumption in the general population invites the need for quality evidence regarding its safety and efficacy. Herein, we synthesize extant literature pertaining to the phytocannabinoid cannabidiol (CBD) and its brain effects. The principle phytocannabinoid Δ9-tetrahydrocannabinol (Δ9-THC) and CBD are the major pharmacologically active cannabinoids. The effect of CBD on brain systems as well as on phenomenological measures (e.g. cognitive function) are distinct and in many cases opposite to that of Δ9-THC. Cannabidiol is without euphoriant properties, and exerts antipsychotic, anxiolytic, anti-seizure, as well as anti-inflammatory properties. It is essential to parcellate phytocannabinoids into their constituent moieties as the most abundant cannabinoid have differential effects on physiologic systems in psychopathology measures. Disparate findings and reports related to effects of cannabis consumption reflect differential relative concentration of Δ9-THC and CBD. Existing literature, notwithstanding its deficiencies, provides empirical support for the hypothesis that CBD may exert beneficial effects on brain effector systems/substrates subserving domain-based phenomenology. Interventional studies with purified CBD are warranted with a call to target-engagement proof-of-principle studies using the research domain criteria (RDoC) framework.

Mental health consequences of exercise withdrawal: A systematic review.
Weinstein, AA, Koehmstedt, C, Kop, WJ
General hospital psychiatry. 2017;:11-18
Abstract
OBJECTIVE A sedentary lifestyle has been associated with mental health disorders. Many medical conditions result in the cessation of exercise, which may increase the risk of developing mental health problems. The purpose of this article is to systematically review the literature examining the effects of exercise withdrawal on mental health. METHOD Literature was searched using PubMed, PsycINFO, and SPORTdiscus for studies that experimentally manipulated the withdrawal of exercise and included mental health as outcome measure. RESULTS A total of 19 studies met inclusion criteria (total N=689 with 385 individuals participating in an exercise withdrawal condition). Exercise withdrawal consistently resulted in increases in depressive symptoms and anxiety. Other mental health outcomes were investigated infrequently. Severe mental health issues requiring clinical intervention after experimentally controlled exercise withdrawal was rare. Heterogeneity in methods and outcomes was observed, especially in terms of the duration of exercise withdrawal (range 1 to 42days, median=7days), with stronger effects if exercise withdrawal exceeded 2weeks. CONCLUSION Experimentally controlled exercise withdrawal has adverse consequences for mental health. These observations in healthy individuals may help to understand the onset of mental health problems in response to acute and chronic medical conditions associated with reduced physical activity. Future research is needed to investigate potential mechanisms explaining the adverse mental health consequences of cessation of exercise that will provide new targets for clinical interventions.

Mindfulness Training for Health Profession Students-The Effect of Mindfulness Training on Psychological Well-Being, Learning and Clinical Performance of Health Professional Students: A Systematic Review of Randomized and Non-randomized Controlled Trials.
McConville, J, McAleer, R, Hahne, A
Explore (New York, N.Y.). 2017;(1):26-45
Abstract
BACKGROUND High levels of stress have been identified in medical students and increasingly in other health profession student population groups. As stress can affect psychological well-being and interfere with learning and clinical performance, there is a clear argument for universities to include health professional student well-being as an outcome in core curriculum. Mindfulness training is a potential construct to manage stress and enhance academic success. OBJECTIVES The aims of this systematic review were to assess the effectiveness of mindfulness training in medical and other health professional student population groups and to compare the effectiveness of the different mindfulness-based programs. DATA SOURCES A literature search was completed using The Cochrane library, Medline, Cinahl, Embase, Psychinfo, and ERIC (proquest) electronic databases from inception to June 2016. Randomized and non-randomized controlled trials were included. Of the potential 5355 articles, 19 met the inclusion criteria. STUDY SELECTION PARTICIPANTS AND INTERVENTIONS Studies focused on medical (n = 10), nursing (n = 4), social work (n = 1), psychology (n = 1), and medical plus other health (n = 3) students. Interventions were based on mindfulness. DATA EXTRACTION The 19 studies included 1815 participants. Meta-analysis was performed evaluating the effect of mindfulness training on mindfulness, anxiety, depression, stress, mood, self-efficacy, and empathy. The effect of mindfulness on academic performance was discussed. DATA SYNTHESIS AND CONCLUSIONS Mindfulness-based interventions decrease stress, anxiety, and depression and improve mindfulness, mood, self-efficacy, and empathy in health profession students. Due to the range of presentation options, mindfulness training can be relatively easily adapted and integrated into health professional training programs.
