Abstract
The oxytocin receptor plays a significant role in peripheral regulation of parturition and lactation. Given this important role, multiple drug discovery programs have been conducted to develop agonists and antagonists for peripheral activity. The role of the oxytocin receptor in the central nervous system is also significant, promoting social interaction, trust, and empathy in humans. As such, molecules that can access the central nervous system and target the oxytocin receptor are of significant interest. Due to the role of the oxytocin receptor in regulating social function and psychological well-being, agonists of this receptor have considerable promise for the treatment of numerous neuropsychiatric conditions. The poor pharmacokinetic properties and blood-brain barrier penetration of peptide-based molecules means nonpeptide compounds have more commonly been the focus for central nervous system activity. This chapter aims to summarize the current standing of peptide and nonpeptide drug discovery for antagonists and agonists of the oxytocin receptor and focusses on centrally active nonpeptidic agonists.

Involvement of oxidative pathways and BDNF in the antidepressant effect of carvedilol in a depression model induced by chronic unpredictable stress. Psychopharmacology (Berl) 2022; 239:297-311. [PMID: 35022822 DOI: 10.1007/s00213-021-05994-6] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/04/2021] [Accepted: 09/30/2021] [Indexed: 01/30/2023]
Abstract
RATIONALE Depression is a severe psychiatric disorder with oxidative imbalance and neurotrophic deficits as underlying mechanisms. OBJECTIVES Based on the antioxidant effects of carvedilol (CARV), here, we aimed to evaluate CARV's effects against depression induced by the chronic unpredictable stress (CUS) model. METHODS Female Swiss mice were submitted to the CUS protocol for 21 days. Between days 15 and 22, the animals received CARV (5 or 10 mg/kg) or desvenlafaxine (DVS 10 mg/kg) orally. On the 22nd day, mice were subjected to behavioral tests to evaluate locomotion, depressive-like behavior (tail suspension test), motivation/self-care with the splash test (ST), social interaction, and working memory Y-maze test. The prefrontal cortex (PFC) and hippocampus were dissected to evaluate alterations of oxidative and brain-derived neurotrophic factor (BDNF). RESULTS The CUS model reduced locomotion and increased grooming latency, while it reduced the number of groomings in the ST. Both doses of CARV and DVS reverted these alterations. In addition, DVS and CARV reversed CUS model-induced working memory and social interaction deficits. The CUS model decreased hippocampal reduced glutathione (GSH), while DVS and CARV increased GSH in the PFC (CARV5) and hippocampus (CARV5 and 10). The CUS model increased nitrite and malondialdehyde (MDA) concentrations in both areas. All treatments reversed nitrite alterations, while CARV10 changed MDA levels in PFC and all treatments in the hippocampus. The CUS model reduced BDNF levels. CARV10 increased BDNF in the PFC, while both doses of CARV increased hippocampal levels of this neurotrophin. CONCLUSIONS CARV presents antidepressant-like effects comparable to those observed with DVS. In addition, it has an antioxidant effect and is capable of increasing BDNF brain concentrations. Further studies are needed to elucidate the mechanisms involved in the antidepressant effect of CARV.

Abstract
Abstract. Affective disorders, specifically Major Depressive Disorder and Bipolar Disorders, show high prevalence, relapse rates, and a high likelihood to develop a chronic course. For the past two decades, research has investigated the neural correlates of emotion processing and emotion regulation in patients with affective disorders. Putative underlying causal mechanisms of dysregulated affect have been informed by knowledge from the intersection of neuroimaging and clinical psychology. More recent investigations also consider processing the role of mostly negative, self-blaming social emotions, which have been linked to treatment resistance and, hence, provide a prolific target for intervention. Several psychotherapeutic treatment approaches already focus on emotion, and here specific knowledge about the mechanisms underlying persistent changes in affect bears the potential to improve the treatment of affective disorders. In this narrative review, we delineate why and how our insights into the neural correlates of emotion processing and regulation can be applied to the treatment of patients with affective disorders.

Impact of total sleep deprivation and related mood changes on approach-avoidance decisions to threat-related facial displays. Sleep 2021; 44:zsab186.

Abstract
STUDY OBJECTIVES Total sleep deprivation is known to have significant detrimental effects on cognitive and socio-emotional functioning. Nonetheless, the mechanisms by which total sleep loss disturbs decision-making in social contexts are poorly understood. Here, we investigated the impact of total sleep deprivation on approach/avoidance decisions when faced with threatening individuals, as well as the potential moderating role of sleep-related mood changes. METHODS Participants (n = 34) made spontaneous approach/avoidance decisions in the presence of task-irrelevant angry or fearful individuals, while rested or totally sleep deprived (27 h of continuous wakefulness). Sleep-related changes in mood and sustained attention were assessed using the Positive and Negative Affective Scale and the psychomotor vigilance task, respectively. RESULTS Rested participants avoided both fearful and angry individuals, with stronger avoidance for angry individuals, in line with previous results. On the contrary, totally sleep deprived participants favored neither approach nor avoidance of fearful individuals, while they still comparably avoided angry individuals. Drift-diffusion models showed that this effect was accounted for by the fact that total sleep deprivation reduced value-based evidence accumulation toward avoidance during decision making. Finally, the reduction of positive mood after total sleep deprivation positively correlated with the reduction of fearful display avoidance. Importantly, this correlation was not mediated by a sleep-related reduction in sustained attention. CONCLUSIONS All together, these findings support the underestimated role of positive mood-state alterations caused by total sleep loss on approach/avoidance decisions when facing ambiguous socio-emotional displays, such as fear.

Effect of Sensory Deprivation of Nasal Respiratory on Behavior of C57BL/6J Mice. Brain Sci 2021; 11:brainsci11121626.

Abstract
Nasal breathing is a dynamic cortical organizer involved in various behaviors and states, such as locomotion, exploration, memory, emotion, introspection. However, the effect of sensory deprivation of nasal respiratory breath (NRD) on behavior remain poorly understood. Herein, general locomotor activity, emotion, learning and memory, social interaction, and mechanical pain were evaluated using a zinc sulfate nasal irrigation induced nasal respiratory sensory deprivation animal model (ZnSO4-induced mouse model). In the open field test, the elevated O-maze test, and forced swim test, NRD mice exhibited depressive and anxiety-like behaviors. In memory-associated tests, NRD mice showed cognitive impairments in the hippocampal-dependent memory (Y maze, object recognition task, and contextual fear conditioning (CFC)) and amygdala-dependent memory (the tone-cued fear conditioning test (TFC)). Surprisingly, NRD mice did not display deficits in the acquisition of conditional fear in both CFC and TFC tests. Still, they showed significant memory retrieval impairment in TFC and enhanced memory retrieval in CFC. At the same time, in the social novelty test using a three-chamber setting, NRD mice showed impaired social and social novelty behavior. Lastly, in the von Frey filaments test, we found that the pain sensitivity of NRD mice was reduced. In conclusion, this NRD mouse model showed a variety of behavioral phenotypic changes, which could offer an important insight into the behavioral impacts of patients with anosmia or those with an impaired olfactory bulb (OB) (e.g., in COVID-19, Alzheimer’s disease, Parkinson’s disease, etc.).

Disordered eating and self-harm as risk factors for poorer mental health during the COVID-19 pandemic: a UK-based birth cohort study. J Eat Disord 2021; 9:155.

Abstract
BACKGROUND Young adults and especially those with pre-existing mental health conditions, such as disordered eating and self-harm, appear to be at greater risk of developing metal health problems during the COVID-19 pandemic. However, it is unclear whether this increased risk is affected by any changes in lockdown restrictions, and whether any lifestyle changes could moderate this increased risk. METHODS In a longitudinal UK-based birth cohort (The Avon Longitudinal Study of Parents and Children, ALSPAC) we assessed the relationship between pre-pandemic measures of disordered eating and self-harm and mental health during the COVID-19 pandemic in 2657 young adults. Regression models examined the relationship between self-reported disordered eating, self-harm, and both disordered eating and self-harm at age 25 years and depressive symptoms, anxiety symptoms and mental wellbeing during a period of eased restrictions in the COVID-19 pandemic (May-July 2020) when participants were aged 27-29 years. Analyses were adjusted for sex, questionnaire completion date, pre-pandemic socioeconomic disadvantage and pre-pandemic mental health and wellbeing. We also examined whether lifestyle changes (sleep, exercise, alcohol, visiting green space, eating, talking with family/friends, hobbies, relaxation) in the initial UK lockdown (April-May 2020) moderated these associations. RESULTS Pre-existing disordered eating, self-harm and comorbid disordered eating and self-harm were all associated with the reporting of a higher frequency of depressive symptoms and anxiety symptoms, and poorer mental wellbeing during the pandemic compared to individuals without disordered eating and self-harm. Associations remained when adjusting for pre-pandemic mental health measures. There was little evidence that interactions between disordered eating and self-harm exposures and lifestyle change moderators affected pandemic mental health and wellbeing. CONCLUSIONS Young adults with pre-pandemic disordered eating, self-harm and comorbid disordered eating and self-harm were at increased risk for developing symptoms of depression, anxiety and poor mental wellbeing during the COVID-19 pandemic, even when accounting for pre-pandemic mental health. Lifestyle changes during the pandemic do not appear to alter this risk. A greater focus on rapid and responsive service provision is essential to reduce the impact of the pandemic on the mental health of these already vulnerable individuals. The aim of this project was to explore the mental health of young adults with disordered eating behaviours (such as fasting, vomiting/taking laxatives, binge-eating and excessive exercise) and self-harm during the COVID-19 pandemic. We analysed data from an established study that has followed children from birth (in 1991 and 1992) up to present day, including during the pandemic when participants were 28 years old. We looked at the relationship between disordered eating and/or self-harm behaviours from before the pandemic and mental health problems (symptoms of depression and anxiety) and mental wellbeing during the pandemic. We also explored whether there were any lifestyle changes (such as changes in sleep, exercise, visiting green space) that might be linked to better mental health and wellbeing in young adults with disordered eating and self-harm. We found that young adults with prior disordered eating and/or self-harm had more symptoms of depression and anxiety, and worse mental wellbeing than individuals without prior disordered eating or self-harm. However, lifestyle changes did not appear to affect mental health and wellbeing in these young adults. Our findings suggest that people with a history of disordered eating and/or self-harm were at high risk for developing mental health problems during the pandemic, and they will need help from mental health services.

Abstract
ABSTRACT Although mentalization is important in somatic symptom disorder (SSD) and major depressive disorder (MDD), it is not fully understood. In this study, we aimed to investigate the relation between somatic and depressive symptoms with mentalization. A total of 48 patients diagnosed with SSD, 50 patients diagnosed with MDD, and 50 healthy individuals, participated the study. The Montgomery-Asperg Depression Scale, Symptom Checklist-90 Revised, and Reading the Mind in the Eyes Test (RMET) were applied to the participants. The patients with SSD showed significantly the lowest performance of theory of mind. There was no significant difference between MDD and healthy controls. High somatization score was found to be a predictor for low RMET scores (95% confidence interval, -0.339; p = 0.014). Mentalization deficit seems to be associated with somatization rather than depression.

Abstract
OBJECTIVE The TREVIDA study aimed to evaluate vortioxetine for the treatment of major depressive disorder (MDD) in Taiwanese adults. METHODS Patients with active depressive episode were recruited in this non-interventional, prospective, multi-site study conducted between June 2019 and August 2020 in Taiwan. Patient eligibility was independent of the physician's decision to prescribe vortioxetine for an MDD episode. Vortioxetine was initiated on the first visit. Depression severity, cognitive function, work productivity, functioning and safety were evaluated over 3 months. RESULTS Overall, 242 patients were analyzed. At baseline, 70.7% and 90.4% of patients had moderately severe-to-severe depression based on PHQ-9 (Patient Health Questionnaire-9) and TDQ (Taiwanese Depression Questionnaire), respectively. By Month 3, significant improvements from baseline in depression severity (mean [SD] changes in PHQ-9, TDQ and CGI-S [Clinical Global Impression-Severity]: -6.3 [7.3]; -13.2 [14.0]; -1.5 [1.3], respectively), cognitive function (mean [SD] change in PDQ-D: -8.0 [17.5]), functioning (mean [SD] change in SDS: -5.4 [7.6]), and presenteeism (38.9% from 56.3%), work productivity loss (40.9% from 58.7%) and activity impairment (43.2% from 61.0%) were observed (p < .001 for all). By month 3, patient-reported (PHQ-9) response and remission rates were 43.4% and 52.9%, respectively; physician-reported (CGI-S) response and remission rates were 29.0% and 31.6%, respectively. Vortioxetine was well-tolerated and no unexpected side effects were reported. CONCLUSIONS Vortioxetine reduced depression severity and improved cognitive function, work productivity, and functioning in Taiwanese patients with MDD in the real-world setting. Vortioxetine was well-tolerated in this Taiwanese population.

Abstract
BACKGROUND The popularization of social media has led to the coalescing of user groups around mental health conditions; in particular, depression. Social media offers a rich environment for contextualizing and predicting users' self-reported burden of depression. Modern artificial intelligence (AI) methods are commonly employed in analyzing user-generated sentiment on social media. In the forthcoming systematic review, we will examine the content validity of these computer-based health surveillance models with respect to standard diagnostic frameworks. Drawing from a clinical perspective, we will attempt to establish a normative judgment about the strengths of these modern AI applications in the detection of depression. METHODS We will perform a systematic review of English and German language publications from 2010 to 2020 in PubMed, APA PsychInfo, Science Direct, EMBASE Psych, Google Scholar, and Web of Science. The inclusion criteria span cohort, case-control, cross-sectional studies, randomized controlled studies, in addition to reports on conference proceedings. The systematic review will exclude some gray source materials, specifically editorials, newspaper articles, and blog posts. Our primary outcome is self-reported depression, as expressed on social media. Secondary outcomes will be the types of AI methods used for social media depression screen, and the clinical validation procedures accompanying these methods. In a second step, we will utilize the evidence-strengthening Population, Intervention, Comparison, Outcomes, Study type (PICOS) tool to refine our inclusion and exclusion criteria. Following the independent assessment of the evidence sources by two authors for the risk of bias, the data extraction process will culminate in a thematic synthesis of reviewed studies. DISCUSSION We present the protocol for a systematic review which will consider all existing literature from peer reviewed publication sources relevant to the primary and secondary outcomes. The completed review will discuss depression as a self-reported health outcome in social media material. We will examine the computational methods, including AI and machine learning techniques which are commonly used for online depression surveillance. Furthermore, we will focus on standard clinical assessments, as indicating content validity, in the design of the algorithms. The methodological quality of the clinical construct of the algorithms will be evaluated with the COnsensus-based Standards for the selection of health status Measurement Instruments (COSMIN) framework. We conclude the study with a normative judgment about the current application of AI to screen for depression on social media.

Trolio V, Mehak A, Schell SE, Racine SE. Extending the scope of the interpersonal psychotherapy model of eating disorders: Integrating the role of 'feeling fat'. Appetite 2021; 166:105441. [PMID: 34090943 DOI: 10.1016/j.appet.2021.105441] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2020] [Revised: 03/29/2021] [Accepted: 05/17/2021] [Indexed: 11/19/2022]
Abstract
The interpersonal psychotherapy model of eating disorders (IPT-ED) argues that interpersonal problems result in negative affect, and that an inability to cope with this negative affect triggers ED symptoms. Relatedly, it is theorized that 'feeling fat' (i.e., the somatic experience of being overweight not entirely explained by one's body mass) results from shifting negative affect onto one's body, which can then be controlled via ED symptoms. Research has yet to identify why negative affect caused by interpersonal problems may trigger ED symptoms as opposed to other maladaptive behaviours. Integrating 'feeling fat' into the IPT-ED may help to explain this relationship. This study examined whether interpersonal problems positively related to ED symptoms via negative affect and 'feeling fat' in 190 undergraduate women (mean age [SD] = 19.05 [1.23]; mean BMI [SD] = 21.76 [3.17]; 72.8% Caucasian). Using both cross-sectional and longitudinal path analyses, we tested the indirect effects of ostracism and peer victimization on binge eating and restricting via negative affect and 'feeling fat' using serial indirect effects analyses. Cross-sectional path analysis revealed significant indirect effects of ostracism on both binge eating and restricting sequentially via negative affect and 'feeling fat', such that ostracism related to negative affect, which related to 'feeling fat', which was ultimately associated with disordered eating behaviours. Longitudinal path analysis replicated the significant indirect effects of ostracism on binge eating sequentially via negative affect and 'feeling fat'. Results suggest that individuals may displace negative feelings that result from ostracism onto their body, triggering 'feelings of fatness' and prompting ED symptoms. Future research should examine 'feeling fat' within the IPT-ED in a sample of individuals with EDs to determine its clinical utility beyond an undergraduate sample.

Abstract
RATIONALE Stress is a well-known risk factor for anhedonia, and its impacts on social reward functions may be mitigated by its controllability. Moreover, there are questions about the effectiveness of selective serotonin reuptake inhibitors (SSRIs) on improving social hedonic functioning deficits characteristic of major depression. OBJECTIVES The current study in male Sprague-Dawley rats investigated the effects of uncontrollable stress on responses to social incentive stimuli and possible modulation by the SSRI escitalopram (ESC). METHODS The effects of inescapable foot-shocks on preferential responses to a conspecific, and to a compartment that was previously paired with the presence of a conspecific, were assessed in a Y-apparatus in rats that received 0, 5, or 10 mg/kg ESC. RESULTS Although inescapable foot-shock exposure did not significantly alter the investigation of the conspecific, it did impair the response to the social-paired compartment and, importantly, this impairment was reversed by ESC. CONCLUSION These results indicate that psychophysical stress can negatively impact reactivity to learned social rewards and that SSRI administration can have positive therapeutic effects.

Abstract
BACKGROUND Stress is a risk factor for unipolar and bipolar mood disorders, but the mechanisms linking stress to specific symptoms remain elusive. Behavioral responses to stress, such as impulsivity and social withdrawal, may mediate the associations between stress and particular mood symptoms. METHODS This study evaluated behavioral mediators of the relationship between self-reported intensity of daily stress and mood symptoms over up to eight weeks of daily diary surveys. The sample included individuals with unipolar or bipolar disorders, or with no psychiatric history (n = 113, ages 15-25). RESULTS Results showed that higher daily stress was related to higher severity of mania, and this pathway was mediated by impulsive behaviors. Higher stress also predicted higher severity of anhedonic depression, and social withdrawal mediated this relationship. A k-means clustering analysis revealed six subgroups with divergent profiles of stress-behavior-symptom pathways. LIMITATIONS Given the observational study design, analyses cannot determine causal relationships amongst these variables. Further work is needed to determine how relationships between these variables may vary based on stressor type, at different timescales, and within different populations. CONCLUSIONS Findings support a theoretical model in which impulsivity and social withdrawal act as behavioral mediators of the relationship between stress and mood symptoms. Additionally, distinct patterns of reactivity distinguished subgroups of people vulnerable to particular types of mood symptoms. These results provide novel information about how stress-reactive behaviors relate to specific mood symptoms, which may have clinical relevance as targets of intervention.

Abstract
While there has been great deal of research conducted on the effects of child sexual abuse (CSA) on trauma symptoms in children and adults, there is less knowledge on the effects on trauma symptoms in female older adult CSA survivors. The aim of this study was to investigate current symptoms of trauma in adult female survivors of child sexual abuse across each successive decade, beginning with eighteen year olds. This retrospective, anonymous online study gathered a sample of 223 adult female survivors of CSA (38 of whom were aged 50-59 (17%), and 20 of whom were 60+ years of age (9%)), and surveyed their trauma history and their current symptomology. In our sample, the survivors with the most severe trauma symptoms were between 18 and 29 years old. Each subsequent decade reported fewer trauma symptoms, with respondents in the 60+ age group reporting the lowest trauma symptom severity. While a cross-sectional study does not allow us to evaluate individuals' experiences over time, these results suggest that the negative impacts of CSA may abate over the life course. Future research should consider these questions longitudinally to explore whether these results are related to survivorship (those with worse outcomes dying younger) and whether these effects endure as female older adults experience physical and mental challenges in later life.

Abstract
Depression is the second leading cause of disability in the world. Despite developing some efficacious treatments, many patients do not respond to the treatment well due to the complexity of depression and unknown mechanisms involved in its pathogenesis. It has been reported that patients with major depressive disorder (MDD) experience autonomic dysfunctions in different aspects. Evidence suggests that modulation of the autonomic nervous system may improve depression. Von Economo neurons (VENs) are shown to be involved in the pathophysiology of some of the neurological and psychological diseases. VENs are also important for the "ego" formation, sense of empathy, intuition, and cognition. These neurons express a high level of adrenoreceptor alpha 1a, which confirms their role in the autonomic function. Here, based on some evidence, I propose the hypothesis that these neurons may play a role in depression, possibly through being involved in the autonomic function. More focused studies on VENs and their possible role in depression is suggested in future. This pathway may open a new window in the treatment of depression.

Abstract
Introduction: Depressive realism literature suggests that depressed individuals’ negative self-view is correlated with less self-serving positivity bias. Also, research suggests some social cognitive advantages for individuals with subclinical levels of depression (dysphoria), especially in identifying negative emotions. This study tested the hypothesis that individuals with dysphoric symptoms show less of a truth bias and are more accurate at detecting deception. Moreover, this effect was expected to be stronger in positive statements (I like) than in negative (I dislike) statements. Finally, a lower judgment confidence and a more accurate assessment of their lie detection ability were expected to be found in individuals with dysphoric symptoms. Methods: Two hundred-sixty-nine participants judged the veracity of 24 video statements. Analyses tested the hypotheses with three different measures of depression: the IPIP-240 Depression Subscale, the PHQ-9, and the DESC-I. Results: In contrast to the assumptions, results found no evidence that individuals with dysphoric symptoms were better at identifying false and true messages in general. While higher scores of the DESC-I were negatively correlated with accuracy in lie detection, the IPIP-240 and the PHQ-9 were found to be not significantly correlated with lie detection accuracy. While for like statements individuals with dysphoric symptoms and individuals without (measured with the DESC-I) were not different in accuracy, individuals with dysphoric symptoms had lower accuracy scores in dislike statements than individuals without. Moreover, the PHQ-9 found lower measures of judgment confidence in individuals with dysphoric symptoms compared to individuals without, while the other depression measurements showed no significant differences. Furthermore, no evidence for a more accurate assessment of lie detection ability in individuals with dysphoric symptoms was found. Discussion: Results and directions for future research are discussed.

Abstract
Objectives: Locating the family systems theory within the life course stress process perspective, this study investigates how husbands' and wives' marital and financial stress were implicated in their subsequent physical health, psychological distress, and loneliness. Methods: Using prospective data from 254 husbands and wives over 27 years, a path model examined the influence of marital stress and family financial stress during midlife (40-50 years) on later-life (65+ years) physical health, psychological distress, and loneliness. Results: For wives, loneliness was a mechanism linking marital stress to their health outcomes and their husbands' physical health. For husbands, physical health was a mechanism linking financial strain to husbands' health outcomes and wives' physical health. Discussion: The findings emphasize the consideration of midlife financial and marital stress for policies and programs for older adults, particularly the prevention of loneliness and improving interpersonal processes, as ways to protect from earlier stressful experiences.

Abstract
Meaningful social interactions are a fundamental human need, the lack of which can pose serious risks to an individual's physical and mental health. Across species, peer-oriented social behaviors are dramatically reshaped during adolescence, a developmental period characterized by dynamic changes in brain structure and function as individuals transition into adulthood. Thus, the experience of social isolation during this critical developmental stage may be especially pernicious, as it could permanently derail typical neurobiological processes that are necessary for establishing adaptive adult behaviors. The purpose of this review is to summarize investigations in which rodents were isolated during adolescence, then re-housed in typical social groups prior to testing, thus allowing the investigators to resolve the long-term consequences of social adversity experienced during adolescent sensitive periods, despite subsequent normalization of the social environment. Here, we discuss alterations in social, anxiety-like, cognitive, and decision-making behaviors in previously isolated adult rodents. We then explore corresponding neurobiological findings, focusing on the prefrontal cortex, including changes in synaptic densities and protein levels, white matter and oligodendrocyte function, and neuronal physiology. Made more urgent by the recent wave of social deprivation resulting from the COVID-19 pandemic, especially amongst school-aged adolescents, understanding the mechanisms by which even transient social adversity can negatively impact brain function across the lifespan is of paramount importance.

Abstract
Social living facilitates individual access to rewards, cognitive resources, and objects that would not be otherwise accessible. There are, however, some drawbacks to social living, particularly when competing for scarce resources. Furthermore, variability in our ability to make social decisions can be associated with neuropsychiatric disorders. The neuronal mechanisms underlying social decision-making are beginning to be understood. The momentum to study this phenomenon has been partially carried over by the study of economic decision-making. Yet, because of the similarities between these different types of decision-making, it is unclear what is a social decision. Here, we propose a definition of social decision-making as choices taken in a context where one or more conspecifics are involved in the decision or the consequences of it. Social decisions can be conceptualized as complex economic decisions since they are based on the subjective preferences between different goods. During social decisions, individuals choose based on their internal value estimate of the different alternatives. These are complex decisions given that conspecifics beliefs or actions could modify the subject's internal valuations at every choice. Here, we first review recent developments in our collective understanding of the neuronal mechanisms and circuits of social decision-making in primates. We then review literature characterizing populations with neuropsychiatric disorders showing deficits in social decision-making and the underlying neuronal circuitries associated with these deficits.

Abstract
Research links interpersonal violence (IPV) perpetrated by a close personal contact, such as a family member or partner, to poor mental health; however, few studies assess associations by gender and explore the community-wide impacts of IPV on rates of depression and posttraumatic stress disorder (PTSD). Using Sinai Community Health Survey (2015-2016), a face-to-face probability survey in 10 Chicago neighborhoods, we examined the association of a broad IPV measure, ever being emotionally or physically abused by a partner or someone important to you, with current depressive (DEPsym) or PTSD symptoms (PTSDsym), stratified by gender. After logistic regression model building, we used direct model-based standardization to calculate adjusted relative prevalence and population attributable prevalence fractions. Of 1,535 respondents, 8% of men and 15% of women had DEPsym; 15% and 20% had PTSDsym, respectively; and 12% and 26% ever experienced IPV, respectively. Controlling for confounders, men who experienced IPV had a 3.6 times (95% confidence interval [CI]: [1.5, 6.8]) higher prevalence of DEPsym and a 2.5 times (95% CI: [1.3, 4.9]) higher prevalence of PTSDsym. Women who experienced IPV had a 2.2 times (95% CI: [1.1, 3.9]) higher prevalence of DEPsym. If the association between IPV and mental health is causal, almost one in three cases of DEPsym (males: 31.7%; females: 27.3%) and one in five cases of PTSDsym (19.2%) among males may be attributed to IPV. Our findings underscore the need for a public health response to IPV and mental health, and additional research on evidence-driven practices that address this association among men and women.

Abstract
We prospectively investigate protective benefits against depression of cortical thickness across nine regions of a Ventral Frontotemporal Network (VFTN), previously associated with spiritual experience. Seventy-two participants at high and low risk for depression (Mean age 41 years; 22-63 years; 40 high risk, 32 low risk) were drawn from a three-generation, thirty-eight year study. FreeSurfer estimated cortical thickness over anatomical MRIs of the brain (Year 30) for each of the nine ROIs. Depression (MDD with SAD-L; symptoms with PHQ; Years 30 and 38) and spirituality (self-report on five phenotypes; Year 35), respectively, were associated with the weighted average of nine regions of interest. VFTN thickness was: 1) positively associated (p<0.01) with two of five spiritual phenotypes, altruism and love of neighbor, interconnectedness at a trend level, but neither commitment nor practice, 2) inversely associated with a diagnosis of MDD (SADS-L Year 30, for any MDD in the past ten years), and 3) prospectively neuroanatomically protective against depressive symptoms (PHQ-9 Year 38) for those at high familial risk.

Abstract
Longitudinal comorbidity of depression and cognitive impairment has been reported by number of epidemiological studies but the underlying mechanisms explaining the link between affective problems and cognitive decline are not very well understood. Imaging studies have typically investigated patients with major depressive disorder (MDD) and mild cognitive impairment (MCI) separately and thus have not identified a structural brain signature common to these conditions that may illuminate potentially targetable shared biological mechanisms. We performed a meta-analysis of. 48 voxel-based morphometry (VBM) studies of individuals with MDD, MCI, and age-matched controls and demonstrated that MDD and MCI patients had shared volumetric reductions in a number of regions including the insula, superior temporal gyrus (STG), inferior frontal gyrus, amygdala, hippocampus, and thalamus. We suggest that the shared volumetric reductions in the insula and STG might reflect communication deficits and infrequent participation in mentally or socially stimulating activities, which have been described as risk factors for both MCI and MDD. We also suggest that the disease-specific structural changes might reflect the disease-specific symptoms such as poor integration of emotional information, feelings of helplessness and worthlessness, and anhedonia in MDD. These findings could contribute to better understanding of the origins of MDD-MCI comorbidity and facilitate development of early interventions.

Wallace T, Myers B. Effects of Biological Sex and Stress Exposure on Ventromedial Prefrontal Regulation of Mood-Related Behaviors. Front Behav Neurosci 2021; 15:737960.

Abstract
The ventral portion of the medial prefrontal cortex (vmPFC) regulates mood, sociability, and context-dependent behaviors. Consequently, altered vmPFC activity has been implicated in the biological basis of emotional disorders. Recent methodological advances have greatly enhanced the ability to investigate how specific prefrontal cell populations regulate mood-related behaviors, as well as the impact of long-term stress on vmPFC function. However, emerging preclinical data identify prominent sexual divergence in vmPFC behavioral regulation and stress responsivity. Notably, the rodent infralimbic cortex (IL), a vmPFC subregion critical for anti-depressant action, shows marked functional divergence between males and females. Accordingly, this review examines IL encoding and modulation of mood-related behaviors, including coping style, reward, and sociability, with a focus on sex-based outcomes. We also review how these processes are impacted by prolonged stress exposure. Collectively, the data suggest that chronic stress has sex-specific effects on IL excitatory/inhibitory balance that may account for sex differences in the prevalence and course of mood disorders.

Within-Person Associations Among Self-Perceptions of Memory, Depressive Symptoms, and Activity Participation in Older Adults. THE GERONTOLOGIST 2021; 61:1107-1117.

Abstract
BACKGROUND AND OBJECTIVES Self-perceptions of memory problems may impact older adults' mood as well as their activity participation, thereby negatively affecting health and well-being. We examined within-person associations among self-reported memory, depressive symptoms, as well as physical, social, and cognitive activity participation in older adults without cognitive impairment. RESEARCH DESIGN AND METHODS Samples were drawn from the Einstein Aging Study (EAS), National Health and Aging Trends Study (NHATS), Rush Memory and Aging Project (MAP), and Minority Aging Research Study (MARS), with over 8,000 participants (65+ years) included across data sets. In a series of coordinated analyses, multilevel structural equation modeling was used to examine within-person relationships over periods of up to 20 years. RESULTS Across EAS, NHATS, and MAP/MARS samples, we found that older adults' self-perceptions of memory did not directly covary with activity participation over time. However, we did find an indirect association in NHATS such that within-person changes in depressive symptoms were associated with changes in self-reported memory, and these contributed to lower physical as well as social activity participation. DISCUSSION AND IMPLICATIONS Older adults' activity participation is important for health, but maximizing engagement requires understanding potentially impeding factors. We found some evidence that as self-perceptions of memory change over time, associated depressive symptoms may contribute to lower activity participation. Inconsistent findings across data sets, however, suggest future research is needed to understand individual characteristics that may influence these relationships.

Abstract
Regardless of a large amount of literature, whether empathy closely relates to depression is far from conclusive. The present study collected previous evidence and performed a meta-analysis to investigate the correlation between empathy and depression. By searching databases, 21 studies and 48 effect sizes were collected. Results showed that empathy was not correlated to depression (r = .006, p = .87). However, subgroup analyses showed that while the relationship between affective empathy and depression was significantly positively correlated (r = .108, p < .01), cognitive empathy was not (r = -.03, p = .26). Additionally, the relationship between empathy and depression varied during development, with a positive correlation in adolescence (r = .084, p < .01) and negative correlation in older adults (r = -.191, p < .001). Results implied that affective empathy might be one of the risk factors for depression, and higher affective empathy might mean more vulnerability to depression. Further studies would help by examining when and how this relationship builds, as well as the contributing factors of its development.

Trajectories of loneliness and objective social isolation and associations between persistent loneliness and self-reported personal recovery in a cohort of secondary mental health service users in the UK. BMC Psychiatry 2021; 21:421. [PMID: 34425767 PMCID: PMC8381487 DOI: 10.1186/s12888-021-03430-9] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/04/2021] [Accepted: 07/01/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Loneliness is a frequent and distressing experience among people with mental health problems. However, few longitudinal studies have so far investigated the trajectories of loneliness and objective social isolation, and the extent to which both issues may impact mental health outcomes among mental health service users. Therefore, this study aims to describe the trajectories of loneliness and objective social isolation and their associations with self-rated personal recovery among people leaving crisis resolution teams (CRTs). METHODS A total of 224 participants receiving care from CRTs (recruited for a large multi-site randomised controlled trial) were included in this longitudinal cohort study. They completed the eight-item University of California at Los Angeles Loneliness Scale (ULS-8), Lubben-Social Network Scale (LNSN-6), and the Questionnaire about the Process of Recovery (QPR) (primary outcome) at baseline, 4- and 18-month follow-up, as well as baseline sociodemographic and clinical variables. RESULTS We compared groups who were persistently lonely (at all time points), intermittently lonely (at one or two time points) and never lonely. After adjusting for all potential confounders and baseline predictive variables, persistent severe loneliness was associated with worse personal recovery at 18-month follow-up compared with the never lonely (reference group) (coef. = - 12.8, 95% CI -11.8, - 3.8, p < .001), as was being intermittently lonely (coef. = - 7.8, 95% CI -18.8, - 6.8, p < .001). The persistently objectively social isolated group (coef. = - 9.8, 95% CI -15.7, - 3.8, p = .001) also had poorer self-rated recovery at 18-month follow-up than those who were not socially isolated at any timepoint (i.e., reference category). CONCLUSION Results suggest that both persistent loneliness and objective social isolation are associated with poorer self-rated recovery following a crisis, compatible with a causal relationship. These findings suggest a potential role for interventions aimed at alleviating loneliness and objective social isolation in improving recovery outcomes for people with mental health symptoms. Increased awareness of both issues among health practitioners is also warranted.

Abstract
Major depressive disorder (MDD) is a complex and common disorder, with many factors involved in its onset and development. The clinical management of this condition is frequently based on the use of some pharmacological antidepressant agents, together with psychotherapy and other alternatives in most severe cases. However, an important percentage of depressed patients fail to respond to the use of conventional therapies. This has created the urgency of finding novel approaches to help in the clinical management of those individuals. Nutraceuticals are natural compounds contained in food with proven benefits either in health promotion or disease prevention and therapy. A growing interest and economical sources are being placed in the development and understanding of multiple nutraceutical products. Here, we summarize some of the most relevant nutraceutical agents evaluated in preclinical and clinical models of depression. In addition, we will also explore less frequent but interest nutraceutical products which are starting to be tested, also evaluating future roads to cover in order to maximize the benefits of nutraceuticals in MDD.

Abstract
Socially engaging robots have been increasingly applied to alleviate depressive symptoms and to improve the quality of social life among different populations. Seeing that depression negatively influences social reward processing in everyday interaction, we investigate this influence during simulated interactions with humans or robots. In this study, 35 participants with mild depression and 35 controls (all from nonclinical populations) finished the social incentive delay task with event-related potential recording, in which they received performance feedback from other persons or from a robot. Compared to the controls, the mild depressive symptom (MDS) group represented abnormalities of social reward processing in the human feedback condition: first, the MDS group showed a lower hit rate and a smaller contingent-negative variation (correlated with each other) during reward anticipation; second, depression level modulated both the early phase (indexed by the feedback-related negativity (FRN)) and the late phase (indexed by the P3) of reward consumption. In contrast, the effect of depression was evident only on FRN amplitude in the robot feedback condition. We suggest that compared to human-human interaction, the rewarding properties of human-robot interaction are less likely to be affected by depression. These findings have implications for the utilization of robot-assisted intervention in clinical practice.

Abstract
Depression is a common disease that seriously endangers the physical and mental health of human beings, and it often coexists with other metabolic disorders such as diabetes and cancer. There have been endless reports on the mechanism, prevention, and cure of comorbidity because of its high incidence and poor prognosis and the increased burden on the family and society. There may be a specific comorbid basis and causal relationship between depression and metabolic diseases. Depression in patients with metabolic disorders can be effectively alleviated through psychotherapy and medication. The timely and effective treatment of depression can significantly improve the quality of life of patients with metabolic disorders, reduce their psychological burden, and promote the effective treatment of metabolic diseases. This study reorganized the research progress on the management of metabolic disorder comorbidity with depression.

Abstract
Levels of sociability are continuously distributed in the general population, and decreased sociability represents an early manifestation of several brain disorders. Here, we investigated the genetic underpinnings of sociability in the population. We performed a genome-wide association study (GWAS) of a sociability score based on four social functioning-related self-report questions from 342,461 adults in the UK Biobank. Subsequently we performed gene-wide and functional follow-up analyses. Robustness analyses were performed in the form of GWAS split-half validation analyses, as well as analyses excluding neuropsychiatric cases. Using genetic correlation analyses as well as polygenic risk score analyses we investigated genetic links of our sociability score to brain disorders and social behavior outcomes. Individuals with autism spectrum disorders, bipolar disorder, depression, and schizophrenia had a lower sociability score. The score was significantly heritable (SNP h2 of 6%). We identified 18 independent loci and 56 gene-wide significant genes, including genes like ARNTL, DRD2, and ELAVL2. Many associated variants are thought to have deleterious effects on gene products and our results were robust. The sociability score showed negative genetic correlations with autism spectrum, disorders, depression, schizophrenia, and two sociability-related traits-loneliness and social anxiety-but not with bipolar disorder or Alzheimer's disease. Polygenic risk scores of our sociability GWAS were associated with social behavior outcomes within individuals with bipolar disorder and with major depressive disorder. Variation in population sociability scores has a genetic component, which is relevant to several psychiatric disorders. Our findings provide clues towards biological pathways underlying sociability.

Abstract
Cognitive bias in depression may increase sensitivity to judgmental appraisal of communicative cues. Nonverbal communication encompassing co-speech gestures is crucial for social functioning and is perceived differentially by men and women, however, little is known about the effect of depression on the perception of appraisal. We investigate if a cognitive bias influences the perception of appraisal and judgement of nonverbal communication in major depressive disorder (MDD). During watching videos of speakers retelling a story and gesticulating, 22 patients with MDD and 22 matched healthy controls pressed a button when they perceived the speaker as appraising in a positive or negative way. The speakers were presented in four different conditions (with and without speech and with natural speaker or as stick-figures) to evaluate context effects. Inter-subject covariance (ISC) of the button-press time series measured consistency across the groups of the response pattern depending on the factors diagnosis and gender. Significant effects emerged for the factors diagnosis (p = .002), gender (p = .007), and their interaction (p < .001). The female healthy controls perceived the gestures more consistently appraising than male controls, the female patients, and male patients whereas the latter three groups did not differ. Further, the ISC measure for consistency correlated negatively with depression severity. The natural speaker video without audio speech yielded the highest responses consistency. Indeed co-speech gestures may drive these ISC effects because number of gestures but not facial shrugs correlated with ISC amplitude. During co-speech gestures, a cognitive bias led to disturbed perception of appraisal in MDD for females. Social communication is critical for functional outcomes in mental disorders; thus perception of gestural communication is important in rehabilitation.

Abstract
ABSTRACT The aim of this study was to investigate the relationship of attachment and coping mechanisms with social functioning in patients with bipolar disorder (BD). Sixty-three patients with BD type I and 63 healthy controls were evaluated. Structured Clinical Interview for DSM-IV Axis I Disorders, Hamilton Depression Rating Scale, Young Mania Rating Scale, Experiences in Close Relationships Questionnaire II, Coping Orientation to Problems Experienced (COPE) inventory, and Social Functioning Scale were used. In the BD group, adaptive coping style scores and attachment avoidance scores were significantly lower than the control group, but mean scores of maladaptive coping styles were higher than the control group. Regression analysis showed that positive reinterpretation and growth, active coping, use of emotional social support, planning, religious activities, and mental disengagement subscales of COPE were significantly associated with social functioning. Psychosocial interventions to strengthen adaptive coping mechanisms may help improve the social functioning in patients with BD.

BACKGROUND Seltorexant, a selective antagonist of human orexin-2 receptors, demonstrated antidepressant effects in a previous exploratory study in patients with major depressive disorder (MDD). METHODS To replicate and extend this observation, a double-blind, adaptive dose-finding study was performed in patients with MDD who had an inadequate response to 1-3 selective serotonin/serotonin-norepinephrine reuptake inhibitors in the current episode. Patients were randomized (2:1:1) to placebo or seltorexant (20 mg or 40 mg) once-daily, administered adjunctively to the antidepressant the patient had been receiving at screening. After an interim analysis (6 weeks post-randomization of 160th patient), newly recruited patients randomly received (3:3:1) placebo or seltorexant 10 mg or 20 mg; the 40-mg dose was no longer assigned. Patients were stratified by baseline Insomnia Severity Index (ISI) scores (ISI ≥ 15 vs < 15). The primary endpoint was change from baseline Montgomery-Åsberg Depression Rating Scale (MADRS) total score at week 6. RESULTS Mixed-Model for Repeated Measures analysis showed a greater improvement in MADRS total score in the seltorexant 20-mg group vs placebo at weeks 3 and 6; least-square means difference (90% CI): -4.5 (-6.96; -2.07), P = .003; and -3.1 (-6.13; -0.16), P = .083, respectively. The improvement in MADRS score at week 6 for seltorexant 20 mg was greater in patients with baseline ISI ≥ 15 vs those with ISI < 15; least-square means difference (90% CI) vs placebo: -4.9 (-8.98; -0.80) and -0.7 (-5.16; 3.76), respectively. The most common (≥5%) adverse events with seltorexant were somnolence, headache, and nausea. CONCLUSIONS A clinically meaningful reduction of depressive symptoms was observed for seltorexant 20 mg. In the subset of patients with sleep disturbance (ISI ≥ 15), a larger treatment difference between seltorexant 20 mg and placebo was observed, warranting further investigation. No new safety signal was identified. REGISTRATION ClinicalTrials.gov Identifier: NCT03227224.

Abstract
Major depressive disorder (MDD) is a common mental disorder. Although the genetic, biochemical, and psychological factors have been related to the development of MDD, it is generally believed that a series of pathological changes in the brain caused by chronic stress is the main cause of MDD. However, the specific mechanisms underlying chronic stress-induced MDD are largely undermined. Recent investigations have found that increased pro-inflammatory cytokines and changes in the inflammatory pathway in the microglia cells in the brain are the potential pathophysiological mechanism of MDD. P2X7 receptor (P2X7R) and its mediated signaling pathway play a key role in microglia activation. The present review aimed to present and discuss the accumulating data on the role of P2X7R in MDD. Firstly, we summarized the research progress in the correlation between P2X7R and MDD. Subsequently, we presented the P2X7R mediated microglia activation in MDD and the role of P2X7R in increased blood-brain barrier (BBB) permeability caused by chronic stress. Lastly, we also discussed the potential mechanism underlying-P2X7R expression changes after chronic stress. In conclusion, P2X7R is a key molecule regulating the activation of microglia. Chronic stress activates microglia in the hippocampus by secreting interleukin- 1β (IL-1β) and other inflammatory cytokines, and increasing the BBB permeability, thus promoting the occurrence and development of MDD, which indicated that P2X7R might be a promising therapeutic target for MDD.

Abstract
BACKGROUND Social functioning impairment has been described in several psychiatric illness, including depressive disorders. It is associated with a deterioration in global functioning and quality of life, thus there is a growing interest in psychosocial functioning remediation interventions. This systematic review aims to review all psychotherapeutic, pharmacological and biological social functioning interventions in depressive disorders. METHODS A systematic search was conducted on PubMed, PsycINFO and Scopus from the first articles to 2019 following the PRISMA guidelines. 72 original papers were extracted from an initial number of 1827, based on the selected eligibility criteria. RESULTS A growing body of research was observed in the last 10 years, with most studies showing a low level of scientific evidence. The main diagnosis found was major depressive disorder and the principal social cognition domains assessed were emotional processing and attributional style. The type of intervention most found was the pharmacological one, followed by psychotherapeutic interventions classified as "non-specific. The efficacy of treatments showed an improvement in depressive symptoms and positive results for emotional processing and attributional style. LIMITATIONS Because there is a lack of well-controlled designs and really few interventions focusing on its remediation, and low homogeneity on the assessment of social aspects across, a comparison of results and the extraction of general conclusions is quite difficult. CONCLUSIONS Although a promising body of literature has been developed in recent years on the improvement of psychosocial functioning in patients with depressive disorders, more studies are needed to clarify relevant aspects in this area.

Abstract
Depression is a common mental disorder and one of the leading causes of disability around the world. Monoaminergic antidepressants often take weeks to months to work and are not effective for all patients. This has led to a search for a better understanding of the pathogenesis of depression as well as to the development of novel antidepressants. One such novel antidepressant is ketamine, which has demonstrated both clinically promising results and contributed to new explanatory models of depression, including the potential role of neuroplasticity in depression. Early clinical trials are now showing promising results of serotonergic psychedelics for depression; however, their mechanism of action remains poorly understood. This paper seeks to review the effect of depression, classic antidepressants, ketamine, and serotonergic psychedelics on markers of neuroplasticity at a cellular, molecular, electrophysiological, functional, structural, and psychological level to explore the potential role that neuroplasticity plays in the treatment response of serotonergic psychedelics.

Abstract
OBJECTIVE Assessment of the rate of false-positive results of the Structured Inventory of Malingered Symptomatology (SIMS) in healthy controls and authentic patients outside the forensic or rehabilitative context. METHODS Beyond the SIMS scores, further variables (PANSS, Hamilton scale, MMSE) were obtained. SIMS scores of healthy individuals were compared with the SIMS scores of the different groups of patients. Additionally, correlations between the SIMS scores and other variables were investigated. RESULTS Patients with psychotic disorders (n=30) or depressive episodes (n=32) more frequently achieved SIMS scores >16 as compared to healthy controls. In comparison, patients with amnestic disorders (n=15) had inconspicuous SIMS scores. Depressed patients with positive SIMS results were significantly more likely to be diagnosed with another psychiatric disorder and the scores of these patients on the Hamilton scale were correlated with positive results on 2 subscales of the SIMS (NI, AF). CONCLUSION If this instrument is to applied in clinical practice in the future, further validation of the SIMS is necessary. The specificity of the SIMS seems to be context-related.

Abstract
After participating in this activity, learners should be better able to:• Identify the effects of dysregulated opioid signalling in depression• Evaluate the use of opioid compounds and ketamine in patients with depression ABSTRACT: Major depressive disorder (MDD) remains one of the leading causes of disability and functional impairment worldwide. Current antidepressant therapeutics require weeks to months of treatment prior to the onset of clinical efficacy on depressed mood but remain ineffective in treating suicidal ideation and cognitive impairment. Moreover, 30%-40% of individuals fail to respond to currently available antidepressant medications. MDD is a heterogeneous disorder with an unknown etiology; novel strategies must be developed to treat MDD more effectively. Emerging evidence suggests that targeting one or more of the four opioid receptors-mu (MOR), kappa (KOR), delta (DOR), and the nociceptin/orphanin FQ receptor (NOP)-may yield effective therapeutics for stress-related psychiatric disorders. Furthermore, the effects of the rapidly acting antidepressant ketamine may involve opioid receptors. This review highlights dysregulated opioid signaling in depression, evaluates clinical trials with opioid compounds, and considers the role of opioid mechanisms in rapidly acting antidepressants.

Abstract
Social interactions and relationships are often rewarding, but the neural mechanisms through which social interaction drives positive experience remain poorly understood. In this study, we developed an automated operant conditioning system to measure social reward in mice and found that adult mice of both sexes display robust reinforcement of social interaction. Through cell-type-specific manipulations, we identified a crucial role for GABAergic neurons in the medial amygdala (MeA) in promoting the positive reinforcement of social interaction. Moreover, MeA GABAergic neurons mediate social reinforcement behavior through their projections to the medial preoptic area (MPOA) and promote dopamine release in the nucleus accumbens. Finally, activation of this MeA-to-MPOA circuit can robustly overcome avoidance behavior. Together, these findings establish the MeA as a key node for regulating social reward in both sexes, providing new insights into the regulation of social reward beyond the classic mesolimbic reward system.

Abstract
Background: Major depressive disorder (MDD) is a highly prevalent mental disorder which causes public health burden and personal disabilities. In people with mental illness, unemployment is an index character of functional impairment. Methods: Using the Taiwan Databank of Persons with Disability (TDPD), we collected the WHO Disability Assessment Schedule 2.0 (WHODAS 2.0) scores for people with MDD-associated disability. We recorded and analyzed the scores of participants during a 3-year period to determine the impact of employment on the trajectory of functional change. Logistic regression was performed to analyze the association between employment and changes in WHODAS 2.0 scores. Results: In people with MDD-associated disability, unemployed individuals present a worse function initially compared to employed individuals. After a 3-year period, the employed group showed a significant functional improvement in the domains of cognition, mobility, and participation. In logistic regression, the odds of having functional improvement were twice as high for those who were employed compared with those who were not. Conclusions: Higher odds of having functional improvement were noted in participants who stay in employment. Programs and strategies to help people with MDD-associated disability resume work warrant more clinical attention and supportive policies from the government.

Abstract
The Social Norms Questionnaire–Dutch version (SNQ-NL) measures the ability to
understand and identify social boundaries. We examined the psychometric
characteristics of the SNQ-NL and its ability to differentiate between patients
with behavioral variant frontotemporal dementia (bvFTD; n =
23), Alzheimer’s dementia (AD; n = 26), chronic psychiatric
disorders (n = 27), and control participants
(n = 92). Between-group differences in the Total score,
Break errors, and Overadhere errors were examined and associations with
demographic variables and other cognitive functions were explored. Results
showed that the SNQ-NL Total Score and Break errors differed between patients
with AD and bvFTD, but not between patients with bvFTD and psychiatric
disorders. Modest correlations with age, sex, and education were observed. The
SNQ-NL Total score and Break errors correlated significantly with emotion
recognition and verbal fluency but not with processing speed or mental
flexibility. In conclusion, the SNQ-NL has sufficient construct validity and can
be used to investigate knowledge of social norms in clinical populations.

Abstract
Humans need meaningful social interactions, but little is known about the consequences of not having them. We examined meaningful social interactions and the lack thereof in patients diagnosed with major depressive disorder (MDD) or social phobia (SP) and compared them to a control group (CG). Using event-sampling methodology, we sampled participants’ everyday social behavior 6 times per day for 1 week in participants’ natural environment. We investigated the quality and the proportion of meaningful social interactions (when they had meaningful social interactions) and degree of wishing for and avoidance of meaningful social interactions (when they did not have meaningful social interactions). Groups differed on the quality and avoidance of meaningful social interactions: Participants with MDD and SP reported perceiving their meaningful social interactions as lower quality (in terms of subjective meaningfulness) than the CG, with SP patients reporting even lower quality than the MDD patients. Further, both MDD and SP patients reported avoiding meaningful social interactions significantly more often than the CG. Although the proportion of meaningful social interactions was similar in all groups, the subjective quality of meaningful social interactions was perceived to be lower in MDD and SP patients. Future research might further identify what variables influenced the reinforcement of the MDD and SP patients so that they engaged in the same number of meaningful social interactions even though the quality of their meaningful social interactions was lower. Increasing awareness of what happens when patients do or do not have meaningful social interactions will help elucidate a potentially exacerbating or maintaining factor of the disorders.

Abstract
Although healthcare workers play a crucial role in helping curb the hazardous health impact of coronavirus disease 2019 (COVID-19), their lives and major functioning have been greatly affected by the pandemic. This study examined the effects of the COVID-19 pandemic on the quality of life (QoL) of Malaysian healthcare workers and its predictive factors. An online sample of 389 university-based healthcare workers completed questionnaires on demographics, clinical features, COVID-19-related stressors, psychological experiences, and perceived social support after the movement lockdown was lifted. All domains of QoL were within the norms of the general population except for social relationship QoL, which was lower than the norm. Multiple linear regression analysis indicated that COVID-19-related stressors (e.g., stress due to annual leave being frozen, loss of daily routine, and frequent exposure to COVID-19 patients) and psychological sequelae (e.g., greater severity of depression, anxiety, and stress) predicted lower QoL. Conversely, greater perceived social support from friends and significant others predicted higher QoL. Clinical and demographic characteristics predicted QoL to a lesser extent: A history of pre-existing medical illness was associated only with lower physical health QoL, whereas older age and being single, divorced, or widowed were only predictive of higher environmental QoL. Efforts to enhance QoL among healthcare workers in response to the pandemic should focus on mitigating COVID-19-related stressors and psychological sequelae and facilitating social support.

Empathy is a complex phenomenon critical for group survival and societal bonds. In addition, there is mounting evidence demonstrating empathic behaviors are dysregulated in a multitude of psychiatric disorders ranging from autism spectrum disorder, substance use disorders, and personality disorders. Therefore, understanding the underlying drive and neurobiology of empathy is paramount for improving the treatment outcomes and quality of life for individuals suffering from these psychiatric disorders. While there is a growing list of human studies, there is still much about empathy to understand, likely due to both its complexity and the inherent limitations of imaging modalities. It is therefore imperative to develop, validate, and utilize rodent models of empathic behaviors as translational tools to explore this complex topic in ways human research cannot. This review outlines some of the more prevailing theories of empathy, lists some of the psychiatric disorders with disrupted empathic processes, describes rat and mouse models of empathic behaviors currently used, and discusses ways in which these models have elucidated social, environmental, and neurobiological factors that may modulate empathy. The research tools afforded to rodent models will provide an increasingly clear translational understanding of empathic processes and consequently result in improvements in care for those diagnosed with any one of the many psychiatric disorders.

Abstract
Glibenclamide is a second-generation sulfonylurea used in the treatment of Type 2 Diabetes Mellitus. The primary target of glibenclamide is ATP-sensitive potassium channels inhibition; however, other possible targets include the control of inflammation and blood-brain barrier permeability, which makes this compound potentially interesting for the management of brain-related disorders. Here, we showed that systemic treatment with glibenclamide (5 mg/kg, p.o., for 21 days) could prevent the behavioral despair and the cognitive dysfunction induced by chronic unpredictable stress (CUS) in mice. In nonhypoglycemic doses, glibenclamide attenuated the stress-induced weight loss, decreased adrenal weight, and prevented the increase in glucocorticoid receptors in the prefrontal cortex, suggesting an impact in hypothalamic-pituitary-adrenal (HPA) axis function. Additionally, we did not observe changes in Iba-1, NLRP3 and caspase-1 levels in the prefrontal cortex or hippocampus after CUS or glibenclamide treatment. Thus, this study suggests that chronic treatment with glibenclamide prevents the emotional and cognitive effects of chronic stress in female mice. On the other hand, the control of neuroinflammation and NLRP3 inflammasome pathway is not the major mechanism mediating these effects. The behavioral effects might be mediated, in part, by the normalization of glucocorticoid receptors and HPA axis.

Predictors of Quality of Life Improvement with Escitalopram and Adjunctive Aripiprazole in Patients with Major Depressive Disorder: A CAN-BIND Study Report. CNS Drugs 2021; 35:439-450. [PMID: 33860922 DOI: 10.1007/s40263-021-00803-2] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 03/06/2021] [Indexed: 12/19/2022]
Abstract
BACKGROUND Non-response to first-line treatment for major depressive disorder (MDD) is common; for such individuals, quality of life (QoL) impairments can be severe. Identifying predictors of QoL changes may support the management of cases with persistent depressive symptoms despite adequate initial pharmacological/psychological treatment. OBJECTIVE The present study aimed to explore predictors of domain-specific QoL improvement following adjunctive aripiprazole treatment for inadequate response to initial antidepressant therapy. METHODS We evaluated secondary QoL outcomes from a CAN-BIND (Canadian Biomarker Integration Network in Depression) study in patients with MDD who did not respond to an initial 8 weeks of escitalopram and received a further 8 weeks of adjunctive aripiprazole (n = 96). Physical, psychological, social, and environmental QoL domains were assessed using the World Health Organization QoL Scale Brief Version (WHOQOL-BREF). Clinician-rated depressive symptoms were assessed using the Montgomery-Åsberg Depression Rating Scale (MADRS). Functioning was measured with the Sheehan Disability Scale (SDS). Satisfaction with medication was assessed with a single item from the Quality of Life Enjoyment and Satisfaction Questionnaire Short Form (Q-LES-Q-SF). Exploratory t-tests were used to describe domain score changes. A hierarchical linear regression was used to explore demographic, clinical, and treatment-related predictors of improvement. RESULTS Across domains, QoL improved with adjunctive aripiprazole treatment. Satisfaction with medication and MADRS and SDS scores similarly improved. Symptom reduction was a predictor for positive change to physical and psychological QoL; functioning improvements were predictive of increases to all QoL domains. Satisfaction with medication predicted improvements to physical and psychological domains, whereas number of medication trials was a predictor of worsening QoL in the physical domain. CONCLUSION The final model explained the most variance in psychological (68%) and physical (67%) QoL. Less variance was explained for environmental (43%) and social QoL (33%), highlighting a need for further exploration of predictors in these domains. Strategies such as functional remediation may have potential to support QoL for individuals with persistent depressive symptoms. CLINICAL TRIALS REGISTRY ClinicalTrials.gov identifier: NCT016557.
