RESUMEN
Understanding the neurobiology of complex behaviors requires measurement of activity in the discrete population of active neurons, neuronal ensembles, which control the behavior. Conventional neuroimaging techniques ineffectively measure neuronal ensemble activity in the brain in vivo because they assess the average regional neuronal activity instead of the specific activity of the neuronal ensemble that mediates the behavior. Our functional molecular photoacoustic tomography (FM-PAT) system allows direct imaging of Fos-dependent neuronal ensemble activation in Fos-LacZ transgenic rats in vivo. We tested four experimental conditions and found increased FM-PAT signal in prefrontal cortical areas in rats undergoing conditioned fear or novel context exposure. A parallel immunofluorescence ex vivo study of Fos expression found similar findings. These findings demonstrate the ability of FM-PAT to measure Fos-expressing neuronal ensembles directly in vivo and support a mechanistic role for the prefrontal cortex in higher-order processing of response to specific stimuli or environmental cues.
RESUMEN
This study examined the association between the degree of religiosity, combined with cultural beliefs, social stigmas, and attitudes towards mental-health treatment in two groups, who, despite having similar cultural and religious affiliation, have experienced different socio-political contexts: Palestinian Muslim college students living in the Occupied Palestinian Territory (OPT) and Israel. The study was guided by Tanhan and Young's (2021) conceptual framework. Methods: A snowball recruitment strategy was applied, using a cross-sectional survey. A total sample size was 214 students, 105 from the OPT and 109 from Israel. Results indicate that students from the OPT (n = 105) did not differ from those living in Israel (n = 109) on religiosity using the Islamic Belief scale, or Attitudes Towards Mental Health treatment (F(1, 189) = 1.07, p = 0.30). However, students from the OPT had higher confidence in mental-health professionals (M = 15.33) than their counterparts (M = 14.59), and women had higher confidence (M = 16.03) than men (M = 13.90). The reliance on traditions for Muslim students over Western mental-health approaches is a critical factor in predicting the attitudes towards students' mental problems and their chosen treatment. Sociopolitical context played a significant role in shaping attitudes toward mental-health providers.

PURPOSE/BACKGROUND: Subanesthetic dosing of intravenous ketamine has shown to be an effective treatment for patients with major depressive disorder. It is unknown whether sympathetic response is related to treatment outcomes. The purpose of this study is to evaluate sympathetic response to ketamine infusions as it relates to treatment outcomes. METHODS/PROCEDURES: This retrospective study examines an outpatient population diagnosed with major depressive disorder or bipolar depression treated with ketamine infusions. Patient characteristics, depressive symptoms measured with the Patient Health Questionnaire (PHQ-9), and vital signs were retrieved by chart review. Patients (n = 145) were categorized as responders (50% reduction in PHQ-9 or less than 10 on final PHQ-9) or nonresponders. Changes in vital signs were recorded during each infusion for the initiation series. FINDINGS/RESULTS: Ketamine responders (51.7%) showed a significant greater increase in systolic blood pressure response during the first infusion when compared with nonresponders. There was no difference seen in diastolic pressure, heart rate, or rate pressure product. Changes in vital signs for subsequent infusions also did not approach significance. IMPLICATIONS/CONCLUSIONS: Physiologic sensitivity to the effects of ketamine may predict treatment responsiveness. Blood pressure and heart rate did not always increase. Further work should examine possible influences on physiologic responses.

Rates of injection drug use (IDU) of opioids have been consistently lower among Black people relative to Non-Hispanic White people despite rising IDU estimates. While explanations have been proposed, no study has explored differences within a clinical sample of Black people in treatment who prefer IDU to non-IDU opioid administration. The purpose of this pilot study was to explore these differences guided by a seminal framework (e.g., market force, social network, and risk-taking characteristics), along with mental health symptoms, needle phobia, and injection perception variables. A purposive sample of 50 Black participants (58.0% male) were recruited from an opioid treatment program in Detroit by their preference for IDU (n = 16) versus non-IDU. The IDU group was younger, less educated, and younger at first treatment episode. They were more likely to report having been told they had bipolar disorder, PTSD, or anxiety, receiving mental health services as adults, and have a spouse/partner and close friends who injected opioids. The non-IDU group endorsed more symptoms of needle phobia. The non-IDU group also agreed more with statements that family and friends believe police mistreat people who inject drugs, and that people who inject opioids have a harder time quitting, are more likely to die from overdose, and have a harder time hiding it from family. These initial findings provide a rationale for a larger study with sex-specific analysis on factors associated with IDU among Black people to inform harm reduction efforts.

BACKGROUND: Exposure to armed conflict and fleeing country of origin for refugees has been associated with poorer psychological health. METHODS: Within the first month following their arrival in the United States, 152 Syrian and Iraqi refugees were screened in a primary care setting for posttraumatic stress disorder (PTSD), anxiety, and depression and rated their perceived health, and perceived level of adversity of violence, armed conflict/flight. The moderating effects of psychiatric symptoms on the relation between perceived adversity and perceived health were assessed. RESULTS: Three models based on diagnosis (PTSD, anxiety, and depression) were tested. While significant effects were found on perceived adversity negatively influencing perceived health across diagnoses, slightly different patterns emerged based on diagnosis. DISCUSSION: Findings suggest that refugees' perception regarding adversity of violence, armed conflict, and flight may contribute to perceived health, with a moderating role of clinically significant symptoms of PTSD, anxiety, and depression.

BACKGROUND: Conflict in Iraq has displaced millions of refugee youth. Warzone exposure and forced migration have unique acute and chronic impacts on youth, yet effects of exposure may not be universal across diverse refugee groups. Understanding how youth from various refugee groups are differentially affected by stress and trauma is critical to allocate resources and implement screening measures with the goal of providing early intervention. METHOD: To identify the effects of warzone exposure and forced migration, a convenience sample of 48 Iraqi refugee youth ages 6-17 was assessed within the first month of arrival to the United States. Youth provided self-reported severity of posttraumatic stress and anxiety symptoms; symptom severity was then compared with an existing sample of 135 Syrian refugee youth to explore whether refugee youth of different nationalities experience the same effects of warzone exposure and forced migration. These data are the baseline for a longitudinal developmental study of refugee health, which also includes parental data. RESULTS: Severity of separation anxiety and negative alterations in cognition and mood were the greatest symptomatic concerns in Iraqi refugee youth. Thirty-eight percent of responding Iraqi youth showed possible indication of an anxiety disorder. Severity of posttraumatic stress symptoms was lower in Iraqi youth compared to Syrian youth. For both Iraqi and Syrian refugee youth, separation anxiety was the most significant concern, with more than 80% of both samples showing a possible indication of clinically significant separation anxiety. CONCLUSION: The present observational study indicated that Iraqi refugee youth experience a range of anxiety and posttraumatic stress symptoms following warzone exposure and forced migration; posttraumatic stress symptoms were less severe in Iraqi versus Syrian youth. Comparing refugee youth of different nationalities is of particular importance, as our results demonstrate that findings from one refugee population cannot easily be generalized to another. Clinical and research efforts should prioritize interventions to address separation anxiety in refugee youth, which was of concern in both samples.
RESUMEN
BACKGROUND: The COVID-19 pandemic may adversely impact the mental health of health care workers (HCWs). To address this issue, it is essential to determine levels of anxiety, depression, and traumatic stress, and sources of stress, and to identify subgroups of HCWs at a higher risk of adverse mental health outcomes during the COVID-19 pandemic. METHODS: We conducted a cross-sectional study of symptoms of mental illness in HCWs in the area surrounding Detroit, Michigan. The online survey included questions about demographics, health and clinical factors, and sources of stress. Several tools were used to assess psychiatric symptoms among HCWs, including the Perceived Stress Scale, the Patient Health Questionnaire depression scale, the Generalized Anxiety Disorder 7-item assessment, and the Posttraumatic Stress Disorder Checklist for DSM-5. The adequacy of personal protective equipment, patient resources, and training for highly contagious diseases were rated. RESULTS: The sample (N = 129) was predominantly female (51.2%) and White (65.9%), with 30.2% screening positive for clinical follow-up to assess anxiety, 20.9% for moderate to severe depression, and 16.3% for elevated traumatic stress. Differences were found by self-reported psychiatric diagnosis and chronic conditions, and role on treatment teams. CONCLUSIONS: Frontline HCWs demonstrate high levels of stress and trauma symptoms. Timely screening and accommodations may be needed during health care crises, such as the COVID-19 pandemic.

Both healthcare workers (HCWs) and psychiatric patients during the COVID-19 pandemic appear to have elevated prevalence of psychiatric symptoms, but little is known about HCWs with psychiatric diagnoses. To examine their response to the pandemic, we analyzed their perspective, and association with psychiatric symptoms and stress among HCW with psychiatric diagnosis. Using an online survey of HCW, we analyzed demographics, work information, health factors, open-ended question, sources of stress and standardized mental health scales (Perceived Stress Scale (PSS), Generalized Anxiety Disorder-7 (GAD-7), Patient Health Questionnaire-8 (PHQ-8), and Posttraumatic Stress Disorder Checklist (PCL)). Sixteen out of 129 HCWs reported a pre-existing psychiatric diagnosis (median age 32 years, 8 were females, 8 work in the emergency department). Their perception of the impact severity on symptoms was significantly correlated with all the mental health scales and with stress from avoiding physical contact. In multivariate analysis, PSS score and PCL score were associated with self-rated impact of the COVID-19 pandemic on symptoms (standardized beta = .51 for PCL and standardized beta = .55 for PSS). GAD-7 score was significantly related to both impact (standardized beta = .44) and stress from avoiding physical contact (standardized beta = .53). HCWs with psychiatric diagnoses reported a range of perception of the impact of the pandemic on their symptoms with increased severity associated with worse psychiatric outcomes and more stress from avoiding physical contact with others. There is a growing importance to protect HCWs mental health, including those with pre-existing psychiatric diagnosis, and proactively counter psychosocial consequences of healthcare crises.

BACKGROUND: One strategy to address the high number of U.S. opioid-related deaths is to restrict high-risk or inappropriate opioid analgesic prescribing and dispensing. Federal and state laws and regulations have implemented restrictions but less is known about commercial and public payers' policies aside from clinician anecdotal reports that these policies are increasing. To assess the number and types of policies with temporal trends, we examined commercial and public (Medicaid) payer policies in one state, Michigan, that has high opioid-related deaths and implemented opioid analgesic prescribing laws. METHODS: Policies for seven large commercial payers and the public payer for 2012-2018 were reviewed and categorized by actions. Joinpoint regression was used to summarize temporal trends on number of policies for all payers and subgroups. RESULTS: Across the 7 years, there were 529 action policies (75.57 (95% confidence intervals (CI) 35.93, 115.22) actions per year) with a range of 36 to 103 actions by payer. Limitations on number of days for initial prescriptions and prior authorizations were the most frequently implemented policy. The temporal trend showed a decline in new policies from 2012 to 2013 but a steady increase from 2014 to 2018 (average annual percent change or AAPC=29.6% (95% confidence intervals 13.2, 48.5%)). The public payer (n=47 policies) showed no increase in number of policies over time (AAPC=2.9% (95% CI -41.6, 61.6%). CONCLUSIONS: The eight commercial and public payers implemented many new policies to restrict opioid analgesic prescribing with a steady increase in the number of such policies implemented from 2014 to 2018. This case study documented that at least in one state with high opioid-related deaths and multiple commercial payers, new and different policies were increasingly implemented creating barriers to patient care. The impact of these policies is understudied, complicating recommendation of best practices.

Intervention adaptations expand the availability of evidence-based treatments across clinical settings and demographically different populations. These adaptations utilize systematic strategies to preserve core components of an intervention. Intervention adaptations made from one public system to another (e.g., juvenile justice to mental health) reduce the need to invent a new intervention. In this column, the authors discuss the adaptation of Treatment Foster Care Oregon, an evidence-based program for treating youths with serious emotional and behavioral disturbance, to Michigan's public mental health system. Challenges encountered in this adaptation and solutions are presented.

INTRODUCTION AND AIMS: Opioids and benzodiazepines (O/BZD) are increasingly involved in drug overdose deaths in the USA. Expanding treatment capacity may reduce these deaths. Knowledge about co-occurring O/BZD admissions compared to opioid admissions (opioid) is needed to plan this expansion. DESIGN AND METHODS: US treatment admissions to specialty facilities for 2011-2017 were analysed for trends and 2017 for group differences. Due to 1.9 million admissions in 2017, comparisons between O/BZD and opioid admissions were summarised as effect sizes. Additional analysis compared the administratively pre-coded category 'other opiates and synthetics' to other opiates and synthetics/benzodiazepines admissions to control for possible similarity in drug source. Differences within O/BZD admissions by primary drug were explored. RESULTS: Although opioid admissions showed a steady increase over time (25.9% to 38.2%), O/BZD admissions showed increases until decline in 2017 (3.2% to 4.0%). In 2017 no factor reached moderate effect size (≥0.2) in group comparisons or within the O/BZD admissions. Heroin was self-reported in 70% of both O/BZD and opioid admissions. DISCUSSION AND CONCLUSIONS: No meaningful US national differences on data routinely collected were found for O/BZD compared to opioid admissions including the subgroup with other opiates and synthetics only. Efforts to expand existing opioid treatment in specialty treatments may help reduce opioid and O/BZD deaths. However, the analysis could not address whether changes in treatment would improve outcomes.

OBJECTIVES: To identify opioids associated with a spike in opioid-related mortality in Wayne County, Michigan, from July 2016 through February 2017. METHODS: We reviewed records from the Wayne County Medical Examiner's Office of 645 people who died because of accidental nonmedically prescribed opioid overdoses from July 2015 through July 2017. We analyzed basic demographics, locations of death, and all opioid toxicology results. Decedents who died in hospitals were excluded. RESULTS: Of the 645 people who died because of nonmedically prescribed opioid overdoses, 65% were male and 63% were White, with an average age of 43 years. Carfentanil was detected in 129 (20%) cases. During the 8-month mortality spike, carfentanil was detected in 114 of 419 cases (average = 27.2%; range = 6.4%-45.2%). Substances most frequently detected with carfentanil included morphine (57%), 6-monoacetylmorphine (38%), fentanyl (43%), norfentanyl (33%), tetrahydrocannabinol (34%), and cocaine (29%). CONCLUSIONS: The Wayne County spike in mortality temporally corresponded with the detection of carfentanil and a proportional increase in opioid overdose deaths with detectable carfentanil. Public Health Implications. The abrupt decrease in carfentanil-detected mortality coincided with an announcement indicating an impending ban on fentanyl analogs from China, which suggests that source control is an effective countermeasure.

Little is known about mental health problems among newly arrived Syrian refugees in the US. It is important to determine the prevalence of common consequences of exposure to trauma and high stress, and provide needed interventions, as these conditions if untreated, can be detrimental to mental and physical health. Adult Syrian refugees (n = 157, 47.1% women, 52.9% men) were screened at one-month mandatory primary care health visit for Posttraumatic Stress Disorder (PTSD), anxiety and depression using PTSD Checklist, and Hopkins Symptoms Checklist. Prevalence of possible diagnoses was high for PTSD (32.2%), anxiety (40.3%), and depression (47.7%). Possible prevalence of depression and anxiety were higher among women, but there was no gender difference for possible PTSD. We found a high prevalence of possible psychiatric disorders related to trauma and stress among Syrian refugees newly resettled in the US. Due to the high prevalence and feasibility of brief screening tools in primary care facilities, we recommend mental health screening during primary care health visits for resettled Syrian refugees.

The guilty but mentally ill (GBMI) verdict was first adopted in Michigan in part to provide treatment for offenders suffering from mental illness. Currently, little is known of its impact among women prisoners. Therefore, the primary aim of this study was to explore if GBMI women (n = 30) spent more time on acute and residential treatment program (RTP) units in prison and/or had a higher number of violence tickets, compared with matched guilty mentally ill prisoners (non-GBMI, n = 30). The secondary aim was to characterize Axis I and Axis II disorders in GBMI female prisoners. Finally, we analyzed the data to find which Axis I and II disorders, if any, were significantly associated with violence tickets in the first year of incarceration and time in acute and RTP settings. Results showed there were no significant differences in time on acute units or the number of violence tickets between groups. Across both groups, those diagnosed with Borderline Personality Disorder had a higher number of violence tickets in the first year of prison (p < .001). The results supported the arbitrariness of the GBMI verdict in the female population and advocated for Dialectical Behavioural Therapy (DBT) programs in prisons.

Refugees frequently experience symptoms of posttraumatic stress and depression, which impede their acculturation in the new host country where they are resettling. There are few longitudinal studies investigating predictors of mental health and acculturation during the early postmigration period. We conducted a longitudinal study of 298 Iraqi refugees, assessing them upon arrival to the U.S. and 1 year after migration. Premigration trauma was associated with increased PTSD and depressive symptoms at baseline, and with decreased acculturation 1 year later. Resilience was associated with depressive symptoms at 1-year follow-up, but not with other resettlement outcomes (PTSD symptoms, English-language skills, or acculturation). PTSD and depressive symptoms at baseline predicted the same symptoms at 1-year follow-up, but not any other resettlement outcomes. The number of chronic diseases at baseline predicted worse PTSD and depressive symptoms, acculturation, and English language skills at 1-year follow up. Postmigratory exposure to daily stressors and less social support predicted worse 1-year outcomes. Results suggest that interventions that aim to improve mental health and promote acculturation among refugees should assess their history of trauma, chronic disorders, and psychological symptoms soon after migration, and promptly provide opportunities for social support.
