Behavioral and psychiatric correlates of brain responses to social feedback.

Maladaptive responses to peer acceptance and rejection arise in numerous psychiatric disorders in adolescence; yet, homogeneity and heterogeneity across disorders suggest common and unique mechanisms of impaired social function. We tested the hypothesis that social feedback is processed similarly to other forms of feedback (e.g., monetary) by examining the correspondence between the brain's response to social acceptance and rejection and behavioral performance on a separate reward and loss task. We also examined the relationship between these brain responses and depression and social anxiety severity. The sample consisted of one hundred and thirteen 16-21-year olds who received virtual peer acceptance/rejection feedback in an event-related potential (ERP) task. We used temporospatial principal component analysis and identified a component consistent with the reward positivity (RewP) or feedback negativity (FN). RewP to social acceptance was not significantly related to reward bias or the FN to social rejection related to loss avoidance. The relationship between RewP and depression severity, while nonsignificant, was of a similar magnitude to prior studies. Exploratory analyses yielded a significant relationship between lower socioeconomic status (SES) and blunted RewP and between lower SES and heightened loss avoidance and blunted reward bias. These findings build on prior work to improve our understanding of the function of the brain's response to social feedback, while also suggesting a pathway for further study, whereby poverty leads to depression via social and reward learning mechanisms.

The reward positivity shows increased amplitude and decreased latency with increasing age in early childhood.

The reward positivity (RewP) is a widely studied measure of neural response to rewards, yet little is known about normative developmental characteristics of the RewP during early childhood. The present study utilized a pooled community sample of 309 4- to 6-year-old children who participated in the Doors guessing game to examine the latency and amplitude of the RewP. Peak detection of the gain-loss difference waveform was conducted for electrodes Fz, Cz, Pz, Oz and the mean activity in a 100 ms window centered around this peak was analyzed. There was a significant decrease in RewP latency (RewP was earlier) and increase in RewP amplitude (RewP magnitude was larger) with advancing age in this cross-sectional analysis. Further, these were independent effects, as both RewP latency and RewP amplitude were uniquely associated with children's age. Moreover, our results indicate that the RewP latency in 4- to 6-year-olds falls outside the 250-350 ms window typically used to quantify the RewP (RewP latency in our sample = 381 ms; SD = 60.15). The internal consistency for latency (.64) and amplitude (.27) of the RewP were characterized by moderate to low reliability, consistent with previous work on the reliability of difference scores. Overall, results demonstrate RewP differences in both timing and amplitude across age in early childhood, and suggest that both amplitude and latency of the RewP might function as individual difference measures of reward processing. These findings are discussed in the context of methodological considerations and the development of reward processing across early childhood.

Men's sheds as an alternative healthcare route? A qualitative study of the impact of Men's sheds on user's health improvement behaviours.

BACKGROUND: Men's health is a globally underrepresented area of research and policy. With men facing numerous healthcare barriers, there are calls for more 'male friendly' approaches to health improvement that take into consideration differing male behaviours and attitudes towards health. Men's Sheds are community-based organisations delivering practical and social activities that encourage positive health behaviours. While Sheds have been recognised for their health and wellbeing benefits to men, research has yet to explore the impacts of Sheds on male health improvement and their potential role as a preventative gendered public health measure. METHODS: The study used in-depth interviews with 62 Shed members from five Sheds to investigate the impacts of Shed activity on the health improvement behaviours and attitudes of Shed users. Findings from the qualitative study were used to propose a set of pathways in which Sheds activity led to positive health engagement. RESULTS: The proposed pathways suggest that there are many different and interlinked ways in which Shed activities can impact on the health behaviours and attitudes of Shed users. Through participation in various practical and social activities in an inclusive environment, Shed users reported increases in their health seeking behaviours, improved perspectives on and management of their personal health, and an increased ability to overcome illness and recover. CONCLUSIONS: Where male friendly health provision has been lacking, this study suggests how Men's Shed activities can provide positive male health outcomes, often in unexpected and non-obvious ways. In particular, the proposed visual pathways are important to inform policymakers and practitioners of the ways in that Sheds may contribute to engaging men in health improvement practices and increase their health knowledge. This study also provides a structure from which further studies can measure and evaluate Shed health impacts.

Filling a void? The role of social enterprise in addressing social isolation and loneliness in rural communities.

Social isolation and loneliness has been classed as a major public health concern due to its negative physical and mental health implications, and living in a remote or rural area is a prominent contributing risk factor. Community-led social enterprise models are recognised in government policy as a potential preventative measure for social isolation and loneliness, yet there is a lack of understanding of their application in rural contexts. The objectives of this paper are to investigate the role of social enterprise in addressing social isolation and loneliness in rural communities, and to explore the pathways in which social enterprise activity may act upon the health and wellbeing of social enterprise beneficiaries. We also discuss the capacity of rural community members to deliver and sustain such services. The study used in-depth interviews over a three-year period with 35 stakeholders from seven social enterprises in the Highlands and Islands of Scotland, including board members, staff, volunteers and service users. Findings showed that social enterprises are successfully providing activities that counteract factors contributing to social isolation and feelings of loneliness, leading to wider health and wellbeing benefits for individuals. However, the sustainability and continuity of social enterprises are questionable due to the burden on smaller populations, limited expertise and knowledge of running social enterprises, and effects on the personal lives of social enterprise volunteers and staff. This study supports suggestions that social enterprises can be generators of health and wellbeing through their varied remit of activities that impact on the social determinants of health. However, it also shows that relying on social enterprise as a particular solution to social isolation and loneliness is precarious due to complexities associated with rurality. Therefore, rural policy and practice must move away from a 'one size fits all' approach to tackling social isolation and loneliness, recognise the need for local level tailored interventions and, through harnessing the potential or rural social enterprises, enable flexible service provision that correlates with rural context.

Altered expression of a two-pore domain (K2P) mechano-gated potassium channel TREK-1 in Hirschsprung's disease.

BACKGROUND: The pathophysiology of Hirschsprung's disease (HSCR) is not fully understood. A significant proportion of patients have persisting bowel symptoms such as constipation, soiling, and enterocolitis despite correctly performed operations. Animal data suggest that stretch-activated 2-pore domain K+ channels play a critical role in the maintenance of intestinal barrier integrity. METHODS: We investigated TREK-1 protein expression in ganglionic and aganglionic regions of HSCR patients (n = 10) vs. normal control colon (n = 10). Protein distribution was assessed by using immunofluorescence and confocal microscopy. Gene and protein expression were quantified using quantitative real-time polymerase chain reaction, western blot analysis, and densitometry. RESULTS: Confocal microscopy of the normal colon revealed strong TREK-1 channel expression in the epithelium. TREK-1-positive cells were decreased in aganglionic and ganglionic bowel compared to controls. TREK-1 gene expression levels were significantly decreased in aganglionic and ganglionic bowel compared to controls (P < 0.05). Western blotting revealed decreased TREK-1 protein expression in aganglionic and ganglionic bowel compared to controls. CONCLUSION: We demonstrate, for the first time, the expression and distribution of TREK-1 channels in the human colon. The decreased TREK-1 expression in the aganglionic and ganglionic bowel observed in HSCR may alter intestinal epithelial barrier function leading to the development of enterocolitis.

Use of anoctamin 1 (ANO1) to evaluate interstitial cells of Cajal in Hirschsprung's disease.

PURPOSE: Interstitial cells of Cajal (ICCs) are pacemaker cells involved in facilitating neurotransmission and the generation of slow electrical waves necessary for colonic peristalsis. Their distribution has been found to be abnormal in the aganglionic and ganglionic colon in Hirschsprung's disease (HSCR) using c-kit-labelling. Anoctamin-1 (ANO1) is a Ca(2+)-activated Cl(-) channel thought to be specifically expressed on ICCs. Unlike c-kit, it plays a key role in ICC pacemaker activity. We aimed to investigate the utility of ANO1 in evaluating the colonic ICC network in HSCR. MATERIALS AND METHODS: We collected full-length pull-through specimens from children with HSCR (n = 10). Control colon specimens were collected at colostomy closure in children with anorectal malformation (n = 6). The distribution of ANO1 and c-kit expression was evaluated using immunofluorescence and confocal microscopy. ANO1 expression was quantified using Western blot analysis. RESULTS: ANO1 was not expressed on 23 % of c-kit immuno-positive cells in the circular muscle; however, 100 % of ANO1-positive ICCs were c-kit positive. The distribution of ANO1-positive ICCs was sparse in aganglionic colon, with a modest reduction in ICCs seen in the ganglionic colon in HSCR compared to controls (p = 0.044). ANO1 protein expression was reduced in aganglionic colon but similar in ganglionic colon relative to controls. CONCLUSIONS: ANO1 is preferential to c-kit in evaluating the ICC network in HSCR due to its specificity and functional importance. Abnormal distribution of ANO1-positive ICCs in the ganglionic colon in HSCR may contribute to persistent bowel symptoms in some patients after pull-through surgery.

National multicentric study on the incidence of alcohol burns during the COVID-19 pandemic.

BACKGROUND: Burns are traumatic wounds that occur when skin is exposed to an amount of energy greater than its maximum dissipation capacity. Alcohol, because it fuels flames and its vapor can cause an explosion, is one of the most common causal agents of burns in Brazil. In late 2019, the COVID-19 pandemic caused a sudden and substantial increase in the use of 70% alcohol (w/v) for antisepsis. OBJECTIVES: To analyze the epidemiological characteristics of alcohol burns during the COVID-19 pandemic in participating Burn Treatment Centers, as well as the severity and treatment of these burns. METHOD: Descriptive, cross-sectional, quantitative and retrospective study based on data obtained from medical records of patients treated in participating Burn Treatment Centers. Data collection included origin, gender, education level, occupation, circumstance of the accident, wound depth and type of treatment. RESULTS: Of eight participating centers, theHospital da Restauraç ão Gov. Paulo Guerra Burn Treatment Center experienced the highest number of alcohol burn patients (38.4%) and male gender accounted for 53.6% of all cases. Predominant occupations were those that involve domestic activities (29%) and 48.6% of patients had not completed elementary school. The most common cause was an accident during cooking (35.5%) followed by suicide attempt (18.3%). More than half (58.6%) of the patients had concomitant second and third degree burns and wound treatment of choice was surgical (43.1%). CONCLUSIONS: The predominant population in this study was male, had a lower level of education, resided in the northeast region and had an occupation carried out in a domestic environment. The latter may reflect the population's longer stay at home due to social constraints caused by the COVID-19 pandemic. There were a large number of second and third degree burns and, as a consequence, a high number of cases in which surgical treatment was required.

The impact of community Men's Sheds on the physical health of their users.

With men more susceptible than women to illness and mortality, and less likely to access primary healthcare services, there have been calls for more male friendly spaces within communities to engage 'hard to reach' men in physical health improvement. Research has shown that Men's Shed (Shed) activity can provide localised support for the mental health and social wellbeing of men within communities, yet less is known about Sheds' impacts on physical health. Drawing on qualitative interviews with 62 Sheds users, this study conceptualises proposed pathways from which Shed activity can lead to positive physical health outcomes. Findings showed that in attending a community Men's Shed and taking part in activities users reported (i) increased mobility and decreased sedentary behavior, (ii) increased ability to overcome physical illness or injury, (iii) improved diet, (iv) decreased alcohol use, and (v) improved physical health knowledge. These findings support wider recommendations for community-based male friendly approaches to physical health improvement, and stress the importance of health and care service delivery beyond boundaries of 'standard' NHS settings, especially when targeting those viewed as 'hard to reach'. While initiatives like Sheds do not offer a replacement of primary healthcare services, they have the potential to fit within existing health and social care practices as an alternative local health-engagement space for men.

Men's Sheds in Scotland: the potential for improving the health of men.

Recent policy focus is on the 'non-obvious' role of community-based organisations in tackling causes of poor health, such as social exclusion. Men's Sheds are a type of community-based organisation offering health and wellbeing benefits to men, despite this not being the explicit reason they exist. A qualitative study was conducted in Scotland to identify sustainability challenges that impact on the ability of Sheds to become a formal healthcare service. Findings showed that a reliance on ageing and retired volunteers to undertake operational tasks and generate income to fund activities affected the ability of Sheds to sustain and develop. Further, members preferred their Sheds to remain informal and flexible to fit their specific needs. Although Sheds are recognised for their health and wellbeing benefits to men, policymakers must recognise that formalising their activities might detract from the Shed's primary aims. This paper summarises specific policy implications and recommendations, taking into consideration tensions between the expectations placed on Sheds to expand into formal healthcare delivery, and the needs of Shed users. HIGHLIGHTS: Men's Shed are known for their ability to contribute to men's health and wellbeing. The potential of Shed to take on a formal healthcare role is questionable because of a reliance on ageing and retired volunteers and a preference to remain informal. Policymakers must recognise that although Sheds might be well placed to offer formal health care this may detract from their primary aims.

Use of Continuous Glucose Monitoring to Assess Parenteral Nutrition-Induced Hyperglycemia in an Adult Patient With Severe COVID-19.

Many patients admitted to the intensive care unit (ICU) are acutely malnourished and often require aggressive and early nutrition support with parenteral nutrition (PN). However, PN-induced hyperglycemia is a predictor of hospital mortality and is associated with increased length of stay. Elevated blood glucose in hospitalized patients with coronavirus disease 2019 (COVID-19) is also associated with increased mortality. Real-time continuous glucose monitoring (rtCGM) is primarily used in the outpatient setting, but there is rapidly growing interest in its applicability to help treat dysglycemia in critically ill patients, especially during the ongoing COVID-19 pandemic. We assessed the use of rtCGM data (Dexcom G6) in a 58-year-old male admitted to the ICU for severe COVID-19 infection, who developed PN-induced hyperglycemia with markedly elevated total daily insulin requirements as high as 128 units. rtCGM was used to safely titrate insulin infusion and monitor glucose levels. No episodes of hypoglycemia were observed, despite an extremely aggressive insulin regimen. This case demonstrates the potential utility of rtCGM in the critical care setting and highlights its potential to help conserve personal protective equipment and minimize unnecessary staff exposure in the setting of COVID-19.

The Relationship Between Depression Symptoms and Adolescent Neural Response During Reward Anticipation and Outcome Depends on Developmental Timing: Evidence From a Longitudinal Study.

BACKGROUND: Blunted neural reward responsiveness (RR) is observed in youth depression. However, it is unclear whether symptoms of depression experienced early in development relate to adolescent RR beyond current symptoms and, further, whether such relationships with RR differ during two key components of reward processing: anticipation and outcome. METHODS: Within a prospective longitudinal study oversampled for early depression, children and caregivers completed semiannual diagnostic assessments beginning in preschool. In later adolescence, mean age = 16.49 years (SD = 0.94), youths' (N = 100) neurophysiological responses to cues signaling likely win and loss and these outcomes were assessed. Longitudinally assessed dimensional depression and externalizing symptoms (often comorbid with depression as well as associated with RR) experienced at different developmental periods (preschool [age 3-5.11 years], school age [6-9.11 years], early adolescence [10-14.11 years], current) were used as simultaneous predictors of event-related potentials indexing anticipatory cue processing (cue-P3) and outcome processing (reward positivity/feedback negativity and feedback-P3). RESULTS: Blunted motivated attention to cues signaling likely win (cue-P3) was specifically predicted by early-adolescent depression symptoms. Blunted initial response to win (reward positivity) and loss (feedback negativity) outcomes was specifically predicted by preschool depression symptoms. Blunted motivational salience of win and loss outcomes (feedback-P3) was predicted by cumulative depression, not specific to any developmental stage. CONCLUSIONS: Although blunted anticipation and outcome RR is a common finding in depression, specific deficits related to motivated attention to cues and initial outcome processing may map onto the developmental course of these symptoms.

Outcomes and Healthcare Provider Perceptions of Real-Time Continuous Glucose Monitoring (rtCGM) in Patients With Diabetes and COVID-19 Admitted to the ICU.

OBJECTIVE: We assessed the clinical utility and accuracy of real-time continuous glucose monitoring (rtCGM) (Dexcom G6) in managing diabetes patients with severe COVID-19 infection following admission to the intensive care unit (ICU). METHODS: We present retrospective analysis of masked rtCGM in 30 patients with severe COVID-19. rtCGM was used during the first 24 hours for comparison with arterial-line point of care (POC) values, where clinicians utilized rtCGM data to adjust insulin therapy in patients if rtCGM values were within 20% of point-of-care (POC) values during the masked period. An investigator-developed survey was administered to assess nursing staff (n = 66) perceptions regarding the use of rtCGM in the ICU. RESULTS: rtCGM data were used to adjust insulin therapy in 30 patients. Discordance between rtCGM and POC glucose values were observed in 11 patients but the differences were not considered clinically significant. Mean sensor glucose decreased from 235.7 ± 42.1 mg/dL (13.1 ± 2.1 mmol/L) to 202.7 ± 37.6 mg/dL (11.1 ± 2.1 mmol/L) with rtCGM management. Improvements in mean sensor glucose were observed in 77% of patients (n = 23) with concomitant reductions in daily POC measurements in 50% of patients (n = 15) with rtCGM management. The majority (63%) of nurses reported that rtCGM was helpful for improving care for patients with diabetes patients during the COVID-19 pandemic, and 49% indicated that rtCGM reduced their use of personal protective equipment (PPE). CONCLUSIONS: Our findings provide a strong rationale to increase clinician awareness for the adoption and implementation of rtCGM systems in the ICU. Additional studies are needed to further understand the utility of rtCGM in critically ill patients and other clinical care settings.

Neural Indicators of Anhedonia: Predictors and Mechanisms of Treatment Change in a Randomized Clinical Trial in Early Childhood Depression.

BACKGROUND: Early childhood depression is associated with anhedonia and reduced event-related potential (ERP) responses to rewarding or pleasant stimuli. Whether these neural measures are indicators of target engagement or treatment outcome is not yet known. METHODS: We measured ERP responses to win and loss feedback in a guessing task and to pleasant versus neutral pictures in young (4.0-6.9 years of age) depressed children before and after randomization to either 18 weeks of Parent-Child Interaction Therapy-Emotion Development (PCIT-ED) or waitlist. RESULTS: Analyses included reward positivity (RewP) data from 118 children randomly assigned to PCIT-ED (n = 60) or waitlist (n = 58) at baseline and late positive potential (LPP) data from 99 children (44 assigned to PCIT-ED vs. 55 assigned to waitlist) at baseline. Children undergoing PCIT-ED showed a greater reduction in anhedonia (F1,103 = 10.32, p = .002, partial η2 = .09). RewP reward responses increased more (F1,86 = 5.98, p = .02, partial η2 = .07) for PCIT-ED, but a greater change in RewP was not significantly associated with a greater reduction in major depressive disorder symptoms (r = -.12, p > .4). Baseline RewP did not predict treatment change. LPPs to positive pictures did not change across treatment, but greater baseline LPPs to positive pictures predicted a higher likelihood of remission from major depressive disorder in children undergoing PCIT-ED (B = 0.14; SE = 0.07; odds ratio = 1.15; p = .03). CONCLUSIONS: The ERP reward response improved in young children with depression during a treatment designed to enhance emotion development, providing evidence of target engagement of the neural systems associated with reward. Further, greater baseline LPP responses to positive pictures was associated with a greater likelihood of depression remission, suggesting that this ERP measure can predict which children are most likely to respond to treatment.

Preschool-Onset Major Depressive Disorder is Characterized by Electrocortical Deficits in Processing Pleasant Emotional Pictures.

Reductions in positive affect are a salient feature of preschool-onset major depressive disorder. Yet, little is known about the psychophysiological correlates of this blunted positive affect and whether reduced physiological responding to pleasant stimuli may differentiate depressed and healthy young children. 120 four-to-seven year old children with current depression and 63 psychiatrically healthy 4-to-7 year old children completed a simple picture-viewing task of pleasant and neutral pictures while event-related potentials (ERPs) were recorded. The early-childhood version of the Kiddie Schedule for Affective Disorders and Depression was used to establish psychiatric diagnoses. A one-way ANCOVA was used to test for group differences in response to pleasant and neutral pictures. Young children with depression showed a reduced response to pleasant vs. neutral pictures (LPP), after controlling for children's age (F(1,180) = 4.15, p = 0.04, η2 = 0.02). The LPP for the children with preschool-onset depression (M = 0.99, SE = 0.65) was significantly smaller than the LPP in the healthy group of young children (M = 3.27, SE = 0.90). This difference did not vary as a function of depression or anhedonia severity within the group with depression or the healthy children. Similar to older children and adolescents with depression, young children with depression display reductions in responsivity to pleasant stimuli as indexed by the LPP. These findings extend prior findings indicating a blunted response to pleasant stimuli in preschool- onset depression. Given the greater neuroplasticity of emotional response and regulation, these findings suggest clinical attention to emotional response to pleasure is an important target in preschool-onset depression.

Men's Sheds: A conceptual exploration of the causal pathways for health and well-being.

Although men have a lower life expectancy than women, and are more susceptible to illness, they have been found to be less likely to engage in health-seeking behaviour. Men's Sheds, as a gendered intervention, has been identified as an effective way to engage men in meaningful activity and gain social support from others. However, links between sheds and health and well-being are not well-documented, and evidence is lacking of the potential causal pathways to health generation. This study aims to develop a plausible empirically based causal theory of how Men's Sheds influence the health and well-being of their participants and to set out future research directions to test this theory. Drawing on a scoping review of academic, peer-reviewed journal articles published between 1990 and 2018, potential causal linkages between shed activity and health and well-being outcomes are synthesised into a logic model framework. Sixteen relevant peer-reviewed journal were identified from the academic literature. The data from the articles are predominantly self-reported, and characterised by small sample sizes and/ or low response rates. Further, information is lacking on the demographics of Men's Shed participants and the contexts in which they exist. Most notably, while there is some evidence on the potential mental health and social well-being impacts of shed activities, physical health is less documented. The study shows that there is a lack of reliable and systematic evidence of the potential causal pathways between Men's Shed activities and health and well-being outcomes. In order to address research gaps, further research is required to test and develop the proposed theory and logic model.

Hippocampal volume and depression among young children.

Clinical depression can occur in young children as early as age three. This very early onset variant of depression shows the same clinical features with developmental adjustments as depression that onsets later in life. One robust neural feature of adult depression is reduced hippocampal volume. We measured hippocampal volume in a sample of 35 children aged 4-7 who were either in a clinical trial for preschool onset depression or were recruited from the community. We used T1 MPRAGE acquisitions on a Siemen's Scanner, with Freesurfer 5.3 used to segment the hippocampus. Depression was measured using the K-SADS early childhood (K-SADS-EC) to create a dimensional depression severity score and the Child Behavior Checklist (CBCL) Depression T-Score. Multilevel models indicated that greater depression severity as measured by either the CBCL Depression Score or the K-SADS-EC was associated with lower hippocampal volume, even controlling for total gray matter, maternal depression, income-to-needs ratio, and stressful life events. These data indicate evidence for reduced hippocampal volume among children with PO-MDD who were more severely depressed. Findings are consistent with the idea that hippocampal volume reductions are an early occurring associated neural marker of MDD, particularly for more severe depression.

Neural Indicators of Anhedonia: Predictors and Mechanisms of Treatment Change in a Randomized Clinical Trial in Early Childhood Depression.

BACKGROUND: Early childhood depression is associated with anhedonia and reduced event-related potential (ERP) responses to rewarding or pleasant stimuli. Whether these neural measures are indicators of target engagement or treatment outcome is not yet known. METHODS: We measured ERP responses to win and loss feedback in a guessing task and to pleasant versus neutral pictures in young (4.0-6.9 years of age) depressed children before and after randomization to either 18 weeks of Parent-Child Interaction Therapy-Emotion Development (PCIT-ED) treatment or waitlist (WL) control condition. RESULTS: Analyses included reward positivity (RewP) data from 118 children randomized to PCIT-ED treatment (n = 60) or WL control condition (n = 58) at baseline and late positive potential (LPP) data from 99 children (44 PCIT-ED treatment vs. 55 WL control condition) at baseline. Children in the PCIT-ED group showed a greater reduction in anhedonia (F1,103 = 10.32, p = .002, partial η2 = .09). RewP reward responses increased more (F1,87 = 5.45, p = .02, partial η2 = .06) for PCIT-ED and a greater change in RewP was associated with a greater reduction in major depressive disorder symptoms (r = -.24, p = .05). Baseline RewP did not predict treatment change. LPPs to positive pictures did not change across treatment, but greater baseline LPPs to positive pictures predicted a higher likelihood of remission from major depressive disorder in the PCIT-ED group (B = 0.14; SE = 0.07; odds ratio = 1.15; p = .03). CONCLUSIONS: The ERP reward response improved in young children with depression during a treatment designed to enhance emotion development, providing evidence of target engagement of the neural systems associated with reward. Further, greater baseline LPP responses to positive pictures were associated with a greater reduction in depression, suggesting that this ERP measure can predict which children are most likely to respond to treatment.

Peer Victimization and Dysfunctional Reward Processing: ERP and Behavioral Responses to Social and Monetary Rewards.

Peer victimization (or bullying) is a known risk factor for depression, especially among youth. However, the mechanisms connecting victimization experience to depression symptoms remains unknown. As depression is known to be associated with neural blunting to monetary rewards, aberrant responsiveness to social rewards may be a key deficit connecting socially stressful experiences with later depression. We, therefore, sought to determine whether adolescents' experiences with social stress would be related to their current response to social rewards over less socially relevant monetary rewards. Neural responses to monetary and social rewards were measured using event-related potentials (ERPs) to peer acceptance and rejection feedback (Island Getaway task) and to monetary reward and loss feedback (Doors task) in a sample of 56 late adolescents/emerging young adults followed longitudinally since preschool. In the Island Getaway task, participants voted whether to "keep" or "kick out" each co-player, providing an index of prosocial behavior, and then received feedback about how each player voted for the participant. Analyses tested whether early and recent peer victimization was related to response to rewards (peer acceptance or monetary gains), residualized for response to losses (peer rejection or monetary losses) using the reward positivity (RewP) component. Findings indicated that both experiencing greater early and greater recent peer victimization were significantly associated with participants casting fewer votes to keep other adolescents ("Keep" votes) and that greater early peer victimization was associated with reduced neural response to peer acceptance. Early and recent peer victimization were significantly more associated with neural response to social than monetary rewards. Together, these findings suggest that socially injurious experiences such as peer victimization, especially those occurring early in childhood, relate to two distinct but important findings: that early victimization is associated with later reduced response to peer acceptance, and is associated with later tendency to reject peers. Findings also suggest that there is evidence of specificity to reward processing of different types; thus, future research should expand studies of reward processing beyond monetary rewards to account for the possibility that individual differences may be related to other, more relevant, reward types.

The DSM-5 Self-Rated Level 1 Cross-Cutting Symptom Measure identifies high levels of coexistent psychiatric symptomatology in patients referred for insomnia treatment.

PURPOSE: Referrals to sleep psychology services, even for a perceived single problem such as insomnia, can present with complex, coexistent psychiatric symptoms and comorbid disorders. This study aimed to assess the feasibility of implementing the DSM-5 Self-Rated Level 1 Cross-Cutting Symptom Measure (CCSM) into a sleep psychology clinic to identify coexistent psychiatric symptomatology in insomnia referrals. PATIENTS AND METHODS: Patients were 50 consecutive referrals to a private sleep psychology service within a sleep disorders center in Melbourne, Australia. Patients who attended sleep psychology services between June 2015 and January 2017 had their clinical records reviewed. Basic demographic information, comorbidities, and responses to the Insomnia Severity Index were gathered. The Diagnostic and Statistical Manual of Mental Disorders Ed. 5 Task Force and Work Groups created the CCSM in 2013 to deal with the issue of coexistent psychiatric symptomatology across mental health conditions, and this measure was included into the sleep psychology intake procedure and patient responses were reviewed. RESULTS: The CCSM was simple and quick to administer and score and revealed high levels of psychiatric symptomatology in sleep psychology referrals. Sleep problems were the most common domain of psychiatric symptomatology reported (86%). Anxiety (66%), depression (64%), anger (64%), and somatic symptoms (50%) were also very common. Suicidal ideation was acknowledged by 26% of patients. In addition, 82% of patients had at least one diagnosed comorbidity upon referral (eg, psychiatric, physical health, or other sleep disorder). CONCLUSION: The findings support the CCSM as a feasible measure for identifying the high levels of coexistent psychiatric symptomatology in patients presenting for insomnia treatment at sleep psychology services.
