Factors influencing medical students and psychiatry residents in Ghana to consider psychiatry as a career option - a qualitative study
(Cambridge University Press, 2020) Agyapong, Vincent I. O.; Ritchie, Amanda; Doucet, Kacy; Agyapong-Opoku, Gerald; Shalaby, Reham; Hrabok, Marianne; Ulzen, Thaddeus; Osei, Akwasi; University of Alberta; Alberta Health Services (AHS); University of Calgary; University of Alabama Tuscaloosa
Background Currently, Ghana has 14 actively practicing psychiatrists and about 26 psychiatric residents for a population of over 28 million people. Previous research suggests a lack of interest by Ghanaian medical students and medical graduates in considering psychiatry as a career option. Objectives To examine the perception of medical students and psychiatry residents in Ghana about the barriers which hinder Ghanaian medical graduates from choosing careers in psychiatry and how these barriers could be overcome. Methods This was a cross-sectional qualitative study with data gathered using focus group discussion. Twenty clinical year medical students were selected through block randomization from the four public medical schools in Ghana and invited to participate in one of two focus group discussions. Also, four psychiatric residents were invited to participate in the focus group discussions. Results The main barriers identified by participants could be grouped under four main themes, namely: (a) myths and stigma surrounding mental health and patients, (b) negative perceptions of psychiatrists, (c) infrastructure and funding issues, (d) lack of exposure and education. To address the barriers presented, participants discussed potential solutions that could be categorized into five main themes, namely: (a) stigma reduction, (b) educating professionals, (c) addressing deficient infrastructure, (d) risk management, and (e) incentivizing the pursuit of psychiatry among students. Conclusion Health policy planners and medical training institutions could consider implementing proposed solutions to identify barriers as part of efforts to improve the psychiatrist to patient ratio in Ghana.
Neurophysiologic evidence for increased retrieval suppression among negative ruminators
(Wiley, 2020) Nair, Aarti; Eyer, Joshua C.; Faust, Mark E.; Loma Linda University; University of Alabama Tuscaloosa; University of North Carolina; University of North Carolina Charlotte
Introduction Events (e.g., seeing a familiar face) may initiate retrieval of associated information (e.g., person's name), but not all cue-initiated memory retrieval is welcome (e.g., trauma). Retrieval suppression refers to the ability to halt unwanted retrieval, and any erosion of memory associations in response to repeatedly excluding a memory from consciousness. The current study sought to examine event-related potential (ERP, averaged scalp electrical recordings) correlates of inhibitory cognitive control of memory retrieval and any linkage of such control to ruminative memory styles. Methods Participants (N = 23) first learned face-picture pairings. ERPs were then recorded as they viewed face cues while either bringing the associated picture to mind (think trial), or not allowing the associated picture to come to mind (no-think trial). Results Emotional valence of learned pictures (negative versus neutral) modulated a posterior (P1, 100-150 ms) ERP associated with attention to the face cue. Memory strategy (think versus no-think) modulated a frontal (P3, 350-450 ms) associated with alerting of the need to control retrieval. Both valence and strategy worked in combination to modulate a late posterior (LC, 450-550 ms) ERP associated with successful memory retrieval. Brooding, a negative form of rumination, was found to be positively correlated with the LC ERP. Conclusion The results suggest early separation of emotional and strategic control of retrieval, but later combined control over access to working memory. Moreover, the positive correlation of brooding and the LC suggest that individuals who are high in application of perseverative strategies to memory retrieval will show greater modulation of the retrieval-related LC ERP.
Cost and effectiveness of one session treatment (OST) for children and young people with specific phobias compared to multi-session cognitive behavioural therapy (CBT): results from a randomised controlled trial
(BMC, 2022) Wang, Han-, I; Wright, Barry; Tindall, Lucy; Cooper, Cindy; Biggs, Katie; Lee, Ellen; Teare, M. Dawn; Gega, Lina; Scott, Alexander J.; Hayward, Emily; Solaiman, Kiera; Davis, Thompson; McMillan, Dean; Gilbody, Simon; Parrott, Steve; University of York - UK; University of Sheffield; Newcastle University - UK; University of Hull; Keele University; Louisiana State University; University of Alabama Tuscaloosa
Background In the UK, around 93,000 (0.8%) children and young people (CYP) are experiencing specific phobias that have a substantial impact on daily life. The current gold-standard treatment-multi-session cognitive behavioural therapy (CBT) - is effective at reducing specific phobia severity; however, CBT is time consuming, requires specialist CBT therapists, and is often at great cost and limited availability. A briefer variant of CBT called one session treatment (OST) has been found to offer similar clinical effectiveness for specific phobia as multi-session CBT. The aim of this study was to assess the cost-effectiveness of OST compared to multi-session CBT for CYP with specific phobias through the Alleviating Specific Phobias Experienced by Children Trial (ASPECT), a two-arm, pragmatic, multi-centre, non-inferiority randomised controlled trial. Methods CYP aged seven to 16 years with specific phobias were recruited nationally via Health and Social Care pathways, remotely randomised to the intervention group (OST) or the control group (CBT-based therapies) and analysed (n = 267). Resource use based on NHS and personal social services perspective and quality adjusted life years (QALYs) measured by EQ-5D-Y were collected at baseline and at six-month follow-up. Incremental cost-effectiveness ratio (ICER) was calculated, and non-parametric bootstrapping was conducted to capture the uncertainty around the ICER estimates. The results were presented on a cost-effectiveness acceptability curve (CEAC). A set of sensitivity analyses (including taking a societal perspective) were conducted to assess the robustness of the primary findings. Results After adjustment and bootstrapping, on average CYP in the OST group incurred less costs (incremental cost was -302.96 pound (95% CI -598.86 pound to -28.61)) pound and maintained similar improvement in QALYs (QALYs gained 0.002 (95% CI - 0.004 to 0.008)). The CEAC shows that the probability of OST being cost-effective was over 95% across all the WTP thresholds. Results of a set of sensitivity analyses were consistent with the primary outcomes. Conclusion Compared to CBT, OST produced a reduction in costs and maintained similar improvement in QALYs. Results from both primary and sensitivity analyses suggested that OST was highly likely to be cost saving.
Examining US Public Early Intervention for Toddlers With Autism: Characterizing Services and Readiness for Evidence-Based Practice Implementation
(Frontiers, 2021) Aranbarri, Aritz; Stahmer, Aubyn C.; Talbott, Meagan R.; Miller, Marykate E.; Drahota, Amy; Pellecchia, Melanie; Barber, Angela B.; Griffith, Elizabeth McMahon; Morgan, Elizabeth H.; Rogers, Sally J.; University of California Davis; Michigan State University; University of Pennsylvania; Pennsylvania Medicine; University of Alabama Tuscaloosa; University of Colorado Anschutz Medical Campus; California State University Sacramento
As the rates of Autism Spectrum Disorder (ASD) increase and early screening efforts intensify, more toddlers with high likelihood of ASD are entering the United States' (US') publicly funded early intervention system. Early intervention service delivery for toddlers with ASD varies greatly based on state resources and regulations. Research recommends beginning ASD-specific evidence-based practices (EBP), especially caregiver-implemented intervention, as early as possible to facilitate the development of social-communication skills and general learning. Translating EBP into practice has been challenging, especially in low-resourced areas. The main goal of this study was to obtain a more comprehensive understanding of public early intervention system structure, service delivery practices, and factors influencing EBP use for children with ASD in the US. Participants (N = 133) included 8 early intervention state coordinators in 7 states, 29 agency administrators in those states, 57 early intervention providers from those agencies, and 39 caregivers of children with ASD receiving services from those providers. Online surveys gathered stakeholder and caregiver perspectives on early intervention services as well as organizational factors related to EBP implementation climate and culture. Stakeholders identified key intervention needs for young children with ASD. In general, both agency administrators and direct providers reported feeling somewhat effective or very effective in addressing most needs of children with ASD. They reported the most difficulty addressing eating, sleeping, family stress, and stereotyped behaviors. Data indicate that children from families with higher income received significantly higher service intensity. While administrators and providers reported high rates of high-quality caregiver coaching (>60%), caregivers reported low rates (23%). Direct providers with more favorable attitudes toward EBP had greater EBP use. In turn, provider attitudes toward EBP were significantly associated with implementation leadership and culture at their agency. Results suggest that publicly funded early intervention programs in the US require additional resources and training for providers and leaders to support improved implementation climate and attitudes toward ASD EBPs. Results also suggest that more state system support is needed to increase use of ASD-specific EBP use, including high-quality caregiver coaching, to better serve toddlers with ASD. Recommendations for implementation strategies are addressed.
Trauma, Mental Health Distress, and Infectious Disease Prevention Among Women Recently Released From Incarceration
(Frontiers, 2022) Johnson, Karen A.; Hunt, Timothy; Puglisi, Lisa B.; Maeng, Daniel; Epa-Llop, Amali; Elumn, Johanna E.; Nguyen, Antoinette; Leung, Ashley; Chen, Rachel; Shah, Zainab; Wang, Jiayi; Johnson, Rachel; Chapman, Benjamin P.; Gilbert, Louisa; El-Bassel, Nabila; Morse, Diane S.; University of Alabama Tuscaloosa; Columbia University; Yale University; University of Rochester
BackgroundU.S. women recently released from incarceration experience significantly higher rates of trauma and exacerbation of mental health conditions, and the period following release has been identified as a window of heightened risk for mental health distress and human immunodeficiency virus (HIV), sexually transmitted infections (STI) and hepatitis C (HCV) transmissions. Despite these vulnerabilities, and an urgent need for supports, optimal engagement strategies remain unclear. WORTH Transitions is a program made up of two evidence-based interventions focused on improving the health of women returning to the community from incarceration with substance use disorders. Combining the two was designed to reduce HIV/STIs/HCV risks and increase overall health treatment engagement using a community health worker led intervention. MethodsWe examined associations between trauma, mental health symptomology, and HIV/STI/HCV outcomes among women who engaged in the WORTH Transitions intervention (N = 206) Specifically, bivariate and longitudinal multivariate models were created to examine associations between trauma and mental health distress (defined as depressive and PTSD symptoms), on (1) types of engagement in HIV/STIs/HCV prevention and behavioral health services; and (2) HIV/STIs/HCV risk outcomes. The women who engaged in the intervention were 18 years and older and some were White, Black and other racial or ethnic minority. ResultsPTSD symptomology and being a Black or indigenous woman of color was significantly (p = 0.014) associated with individual or group session engagement. Neither trauma nor PTSD symptoms were associated with higher HIV/STIs/HCV risks. Instead, relative to those who did not engage in HIV/STI/HCV risky behaviors, PTSD symptomology (p = 0.040) was associated with more than 3-fold increase in the probability of being lost to follow up (relative risk ratio = 3.722). ConclusionGiven the impact of PTSD-related symptoms on driving both engagement in HIV/STIs/HCV prevention services and intervention attrition among women leaving incarceration, physical and behavioral health interventions must be both overtly trauma- and mental health-informed. As was the case with WORTH Transitions, physical and behavioral health services for this population must include intentional and active support of the forms of treatment participants endorse to ensure maximal engagement.
Socio-Ecological Context of Sleep: Gender Differences and Couples' Relationships as Exemplars
(Springer, 2022) Decker, Andrea N.; Fischer, Alexandra R.; Gunn, Heather E.; University of Alabama Tuscaloosa
Purpose of Review We summarized recent findings on insufficient sleep and insomnia, two prominent sleep issues that impact public health. We demonstrate the socio-ecologial impact of sleep health with findings on gender and couples' relationships as exemplars. Recent Findings Robust gender differences in sleep duration and insomnia are due to biological and socio-ecological factors. Gender differences in insufficient sleep vary by country of origin and age whereas gender differences in insomnia reflect minoritized identities (e.g., sexual, gender). Co-sleeping with a partner is associated with longer sleep and more awakenings. Gender differences and couples' sleep were affected by intersecting social and societal influences, which supports a socio-ecological approach to sleep. Recent and seminal contributions to sleep health highlight the importance of observing individual sleep outcomes in a socio-ecological context. Novel methodology, such as global measures of sleep health, can inform efforts to improve sleep and, ultimately, public health.
The role of the broader autism phenotype in anxiety and depression in college-aged adults
(Frontiers, 2023) Kurtz, McKayla R.; Kana, Rajesh K.; Rivera, Daphne L.; Newman, Sharlene D.; University of Alabama Tuscaloosa; Indiana University Bloomington
The current study examines the relationship between the presence of autistic traits and anxiety and mood disorders in young adults from different racial groups. A representative sample from a predominately white university (2,791 non-Hispanic White (NHW) and 185 Black students) completed the broad autism phenotype questionnaire (BAPQ), a measure of depression (Patient Health Questionnaire, PHQ-9), and anxiety (Generalized Anxiety Disorder, GAD-7). Statistical Package for Social Sciences (SPSS) was used to perform two multiple regression analyses to determine the association between race, BAPQ score and anxiety and depression symptoms. The current study found a stronger association between autistic traits had depression and anxiety symptoms in Black participants than did NHW participants. These findings underscore the association between autistic traits and anxiety and depression in Black communities, and the need for further studies on this topic area. Additionally, it highlights the importance of improving access to mental health care for this population.
Seizure prediction: Methods
(Elsevier, 2011) Carney, Paul R.; Myers, Stephen; Geyer, James D.; University of Florida; University of Alabama Tuscaloosa
Epilepsy, one of the most common neurological diseases, affects over 50 million people worldwide. Epilepsy can have a broad spectrum of debilitating medical and social consequences. Although antiepileptic drugs have helped treat millions of patients, roughly a third of all patients have seizures that are refractory to pharmacological intervention. The evolution of our understanding of this dynamic disease leads to new treatment possibilities. There is great interest in the development of devices that incorporate algorithms capable of detecting early onset of seizures or even predicting them hours before they occur. The lead time provided by these new technologies will allow for new types of interventional treatment. In the near future, seizures may be detected and aborted before physical manifestations begin. In this chapter we discuss the algorithms that make these devices possible and how they have been implemented to date. We also compare and contrast these measures, and review their individual strengths and weaknesses. Finally, we illustrate how these techniques can be combined in a closed-loop seizure prevention system.

Prevalence of mental health disorders among low-income African American adolescents
(Springer, 2013) Byck, Gayle R.; Bolland, John; Dick, Danielle; Ashbeck, Alan W.; Mustanski, Brian S.; Northwestern University; Feinberg School of Medicine; University of Alabama Tuscaloosa; Virginia Commonwealth University
Data on the prevalence of mental health disorders for low-income, urban African American adolescents are scarce. This study presents data about the burden of mental disorders for this understudied population. Mental disorders were assessed using the Diagnostic Interview Schedule for Children (C-DISC), Youth Self-Report (YSR), and Child Behavior Checklist (CBCL) among a sample of adolescents and their caregivers from very impoverished neighborhoods in a Southern city. Based on the C-DISC, 3.8, 5.1 and 7.7 % of adolescents met diagnostic criteria for major depression, post-traumatic stress disorder, and conduct disorder, respectively. There were significant differences among some of the mental health disorders based on adolescent and caregiver characteristics such as sex, school status, caregiver work status, and income level. We found a low prevalence of alcohol, marijuana, and substance abuse and dependence disorders. Information about the prevalence of mental health disorders in specific communities and populations can assist in addressing unmet needs, planning for services and treatment, and reducing health disparities.
School Outcomes of Aggressive-Disruptive Children: Prediction From Kindergarten Risk Factors and Impact of the Fast Track Prevention Program
(Wiley, 2013) Conduct Problems Prevention Res Gr; Bierman, Karen L.; Coie, John; Dodge, Kenneth; Greenberg, Mark; Lochman, John; McMohan, Robert; Pinderhughes, Ellen; Pennsylvania State University; Pennsylvania State University - University Park; Duke University; University of Alabama Tuscaloosa; Simon Fraser University; Tufts University
A multi-gate screening process identified 891 children with aggressive-disruptive behavior problems at school entry. Fast Track provided a multi-component preventive intervention in the context of a randomized-controlled design. In addition to psychosocial support and skill training for parents and children, the intervention included intensive reading tutoring in first grade, behavioral management consultation with teachers, and the provision of homework support (as needed) through tenth grade. This study examined the impact of the intervention, as well as the impact of the child's initial aggressive-disruptive behaviors and associated school readiness skills (cognitive ability, reading readiness, attention problems) on academic progress and educational placements during elementary school (Grades 14) and during the secondary school years (Grades 710), as well as high school graduation. Child behavior problems and skills at school entry predicted school difficulties (low grades, grade retention, placement in a self-contained classroom, behavior disorder classification, and failure to graduate). Disappointingly, intervention did not significantly improve these long-term school outcomes. Aggr. Behav. 39:114130, 2013. (c) 2013 Wiley Periodicals, Inc.
Abnormal partitioning of hexokinase 1 suggests disruption of a glutamate transport protein complex in schizophrenia
(Elsevier, 2014) Shan, Dan; Mount, Daniel; Moore, Stephen; Haroutunian, Vahram; Meador-Woodruff, James H.; McCullumsmith, Robert E.; University of Alabama Birmingham; University of Alabama Tuscaloosa; Icahn School of Medicine at Mount Sinai
Excitatory amino acid transporter 2 (EAAT2) belongs to a family of Na+ dependent glutamate transporters that maintain a low synaptic concentration of glutamate by removing glutamate from the synaptic cleft into astroglia and neurons. EAAT2 activity depends on Na+ and K+ gradients generated by Na+/K+ ATPase and ATP. Hexokinase 1 (HK1), an initial enzyme of glycolysis, binds to mitochondrial outer membrane where it couples cytosolic glycolysis to mitochondrial oxidative phosphorylation, producing ATP utilized by the EAAT2/Na+/K+ ATPase protein complex to facilitate glutamate reuptake. In this study, we hypothesized that the protein complex formed by EAAT2, Na+/K+ ATPase and mitochondrial proteins in human postmortem prefrontal cortex may be disrupted, leading to abnormal glutamate transmission in schizophrenia. We first determined that EAAT2, Na+/K+ ATPase, HK1 and aconitase were found in both EAAT2 and Na+/K+ ATPase interactomes by immunoisolation and mass spectrometry in human postmortem prefrontal cortex. Next, we measured levels of glutamate transport complex proteins in subcellular fractions in the dorsolateral prefrontal cortex and found increases in the EAAT2B isoform of EAAT2 in a fraction containing extrasynaptic membranes and increased aconitase 1 in a mitochondrial fraction. Finally, an increased ratio of HK1 protein in the extrasynaptic membrane/mitochondrial fraction was found in subjects with schizophrenia, suggesting that HK1 protein is abnormally partitioned in this illness. Our findings indicate that the integrity of the glutamate transport protein complex may be disrupted, leading to decreased perisynaptic buffering and reuptake of glutamate, as well as impaired energy metabolism in schizophrenia.

Effects of Nativity, Length of Residence, and County-Level Foreign-Born Density on Mental Health Among Older Adults in the US
(Springer, 2016) Choi, Sunha; Kim, Giyeon; Lee, Sungkyu; University of Tennessee Knoxville; University of Alabama Tuscaloosa; Soongsil University
Using the 2004-2007 Medical Expenditure Panel Survey data that are linked to county-level data from the Area Health Resources Files, this study examined whether the healthy immigrant effect applies to mental health of foreign-born older adults. Additionally, testing a protective ethnic density effect on older foreign-born individuals' mental health, this study examined how the percentage of foreign-born population in the county affected the relationship between older adults' immigration status (U.S.-nativity and length of residence in the U.S.) and their mental health status. The sample included 29,011 individuals (level-1) from 920 counties (level-2) across 50 states and D.C. Using the Mental Component Summary of the Short-Form 12, the Kessler Index (K-6), and the Patient Health Questionnaire (PHQ-2), U.S.-born individuals (n = 24,225), earlier immigrants (aeyen15 years in the U.S.; n = 3866), and recent immigrants (< 15 years in the U.S.; n = 920) were compared. The results indicate that recent immigrants showed worse mental health on all three measures compared with U.S.-born individuals and on the K-6 and PHQ-2 compared with earlier immigrants. Higher county-level foreign-born densities were associated with worse mental health status of individuals. However, the significant interactions found in the full conditional multilevel models indicated that the high foreign-born density functioned as a risk factor for worse mental health only among recent immigrants but not among the U.S.-born. In conclusion, the results revealed the vulnerability of older recent immigrants, especially those living in the counties with high foreign-born densities.
Energy intake estimation from counts of chews and swallows
(Elsevier, 2015) Fontana, Juan M.; Higgins, Janine A.; Schuckers, Stephanie C.; Bellisle, France; Pan, Zhaoxing; Melanson, Edward L.; Neuman, Michael R.; Sazonov, Edward; University of Alabama Tuscaloosa; University of Colorado Anschutz Medical Campus; Clarkson University; INRAE; Institut National de la Sante et de la Recherche Medicale (Inserm); Universite Paris 13; heSam Universite; Conservatoire National Arts & Metiers (CNAM); Children's Hospital Colorado; Michigan Technological University
Current, validated methods for dietary assessment rely on self-report, which tends to be inaccurate, timeconsuming, and burdensome. The objective of this work was to demonstrate the suitability of estimating energy intake using individually-calibrated models based on Counts of Chews and Swallows (CCS models). In a laboratory setting, subjects consumed three identical meals (training meals) and a fourth meal with different content (validation meal). Energy intake was estimated by four different methods: weighed food records (gold standard), diet diaries, photographic food records, and CCS models. Counts of chews and swallows were measured using wearable sensors and video analysis. Results for the training meals demonstrated that CCS models presented the lowest reporting bias and a lower error as compared to diet diaries. For the validation meal, CCS models showed reporting errors that were not different from the diary or the photographic method. The increase in error for the validation meal may be attributed to differences in the physical properties of foods consumed during training and validation meals. However, this may be potentially compensated for by including correction factors into the models. This study suggests that estimation of energy intake from CCS may offer a promising alternative to overcome limitations of self-report. (C) 2014 Elsevier Ltd. All rights reserved.
Emergency department utilization among Medicaid beneficiaries with schizophrenia and diabetes: The consequences of increasing medical complexity
(Elsevier, 2014) Shim, Ruth S.; Druss, Benjamin G.; Zhang, Shun; Kim, Giyeon; Oderinde, Adesoji; Shoyinka, Sosunmolu; Rust, George; Morehouse School of Medicine; Emory University; Rollins School Public Health; University of Alabama Tuscaloosa; University of Missouri Columbia
Objective: Individuals with both physical and mental health problems may have elevated levels of emergency department (ED) service utilization either for index conditions or for associated comorbidities. This study examines the use of ED services by Medicaid beneficiaries with comorbid diabetes and schizophrenia, a dyad with particularly high levels of clinical complexity. Methods: Retrospective cohort analysis of claims data for Medicaid beneficiaries with both schizophrenia and diabetes from fourteen Southern states was compared with patients with diabetes only, schizophrenia only, and patients with any diagnosis other than schizophrenia and diabetes. Key outcome variables for individuals with comorbid schizophrenia and diabetes were ED visits for diabetes, mental health-related conditions, and other causes. Results: Medicaid patients with comorbid diabetes and schizophrenia had an average number of 7.5 ED visits per year, compared to the sample Medicaid population with neither diabetes nor schizophrenia (1.9 ED visits per year), diabetes only (4.7 ED visits per year), and schizophrenia only (5.3 ED visits per year). Greater numbers of comorbidities (over and above diabetes and schizophrenia) were associated with substantial increases in diabetes-related, mental health-related and all-cause ED visits. Most ED visits in all patients, but especially in patients with more comorbidities, were for causes other than diabetes or mental health-related conditions. Conclusion: Most ED utilization by individuals with diabetes and schizophrenia is for increasing numbers of comorbidities rather than the index conditions. Improving care in this population will require management of both index conditions as well as comorbid ones. (C) 2013 Elsevier B.V. All rights reserved.
Whose Responsibility Is It to Dismantle Medical Mistrust? Future Directions for Researchers and Health Care Providers
(Routledge, 2019) Jaiswal, Jessica; University of Alabama Tuscaloosa; Rutgers State University New Brunswick; New York University; Yale University
Medical mistrust persists and appears to be growing. The public health literature on medical mistrust has largely focused on mistrust among Black and African American populations due to legacies of abuse and mistreatment, such as the infamous Tuskegee Syphilis Study. However, research is now emerging that explores mistrust among various populations and in varying contexts, and the literature now largely emphasizes the role of ongoing, present-day social and economic inequalities in shaping and sustaining mistrust, particularly among populations who experience staggering health disparities. This special issue showcased nine articles exploring medical mistrust among diverse populations, exploring a wide array of topics and spanning myriad methodologies. In addition to a rigorous systematic review of the literature, this issue covers several critical subareas of the health disparities literature, including preventative health screenings among Black men, discrimination and cultural factors among rural Latinx communities, health care satisfaction among Latina immigrant women, the complex relationship between HIV testing and "conspiracy beliefs" among Black populations, pre-exposure prophylaxis use among transgender women, the impacts of mass incarceration on HIV care, eHealth interventions to address chronic diseases among sexual minority men of color, and participatory research to engage underserved populations as co-researchers. The purpose of this article is to provide a brief summary of the nine manuscripts in this special issue and to outline some recommendations and future directions for research on medical mistrust.
Food insecurity, mental distress and suicidal ideation in rural Africa: Evidence from Nigeria, Uganda and Ghana
(Sage, 2019) Sweetland, Annika Claire; Pala, Andrea Norcini; Mootz, Jennifer; Kao, Jennifer Chien-Wen; Carlson, Catherine; Oquendo, Maria A.; Cheng, Bryan; Belkin, Gary; Wainberg, Milton; Columbia University; University of Alabama Tuscaloosa; University of Pennsylvania; Pennsylvania Medicine; New York City Department of Health & Mental Hygiene
Background: In sub-Saharan Africa, mental and substance-related disorders account for 19% of all years lived with disability, yet the intersection between poverty and mental distress is poorly understood since most psychiatric research is conducted in high-income countries. Aims: To examine the prevalence of and associations between food insecurity, mental distress and suicidal ideation in three rural village clusters in sub-Saharan Africa. Method: Cross-sectional multivariate analysis of sociodemographic variables associated with mental distress and suicidal ideation in three countries. The sample included 1,142 individuals from three rural village clusters in Nigeria (n = 380), Uganda (n = 380) and Ghana (n = 382). Food insecurity was measured based on the number of months in the previous year that the respondent's family reported being 'unable to eat two square meals per day'. Mental distress was assessed using the Kessler non-specific psychological distress scale (K6) and suicidal ideation was measured using an item from PRIME-MD. Other sociodemographic variables included gender, age, literacy and occupation. Results: The prevalence of individuals with moderate or severe mental distress in Nigeria, Uganda and Ghana were higher than previously reported in the literature: 35.5%, 30.8% and 30.4%, respectively, and suicidal ideation rates were 29.7%, 21.3% and 10.9%. No differences were observed in mental distress between men and women in any of the sites. Being a farmer (vs student or other) was protective for mental distress in two sites (Uganda and Ghana) but no other social indicators, such as age, gender, literacy and food insecurity, were significantly associated with mental distress. Risk for suicidal ideation differed across sites: it was associated with food insecurity in Nigeria, female gender in Uganda, and older age in Uganda. Conclusions: Mental distress and suicidal ideation were highly prevalent in three settings of extreme poverty across all groups, in ways that were not always consistent with the global literature. These findings suggest that more research is needed in to better understand the social etiology of mental distress in sub-Saharan Africa.
Towards a More Inclusive and Dynamic Understanding of Medical Mistrust Informed by Science
(Routledge, 2019) Jaiswal, Jessica; Halkitis, Perry N.; University of Alabama Tuscaloosa; Rutgers State University New Brunswick; Yale University; Rutgers State University Medical Center; Rutgers State University Camden
Mistrust of medical advances and the medical professions continues to persist, and is perhaps increasing. The popular press has documented the growing number of parents globally whose concerns around childhood vaccination, albeit based on faulty scientific information, has led to the anti-vax movement which has already resulted in outbreaks of measles in various parts of the U.S. In recent years, the AIDS Healthcare Foundation has increased speculation and mistrust with regard to the denialism of the effectiveness of pre-exposure prophylaxis (PrEP) to avert HIV infections, again based on misinformation. However, in other cases, medical mistrust reflects the very real historical and ongoing injustices experienced by socially and economically marginalized groups. Whether the genesis of the mistrust is based on fact or fallacy, the results may be similar. There are myriad negative consequences associated with medical mistrust, including lower utilization of healthcare and poorer management of health conditions. Mistrust is thought to provide a partial explanation for staggering health disparities, particularly among Black and African American people, and much of the public health and medical literature cites the infamous Tuskegee Study as a main catalyst for this persistent health-related mistrust among people of color and other groups who experience social and economic vulnerability. While mistrust is often referred to as a phenomenon existing within an individual or community, we must rethink this conceptualization and instead locate mistrust as a phenomenon created by and existing within a system that creates, sustains and reinforces racism, classism, homophobia and transphobia, and stigma. The purpose of this article is to briefly address the state of the medical mistrust literature, and to provide a summary of the articles included in this special issue on medical mistrust. Although the scholarship in this issue addresses diverse methodologies, outcomes and populations, they share a message: social inequality drives mistrust.
Misaligned core body temperature rhythms impact cognitive performance of hospital shift work nurses
(Elsevier, 2019) Molzof, Hylton E.; Prapanjaroensin, Aoyjai; Patel, Vivek H.; Mokashi, Mugdha, V; Gamble, Karen L.; Patrician, Patricia A.; University of Alabama Birmingham; University of Alabama Tuscaloosa
Circadian rhythms greatly influence 24-h variation in cognition in nearly all organisms, including humans. Circadian clock impairment and sleep disruption are detrimental to hippocampus-dependent memory and negatively influence the acquisition and recall of learned behaviors. The circadian clock can become out of sync with the environment during circadian misalignment. Shift work represents a real-world model of circadian misalignment that can be studied for its physiological implications. The present study aimed to test the hypothesis that circadian misalignment disrupts vigilance and cognitive performance on occupationally relevant tasks using shift work as a model. As such, we sought to (1) explore the general effects of night- and day-shift worker schedules on sleep-wake parameters and core body temperature (CBT) phase, and (2) determine whether shift-type and CBT phase impact cognitive performance and vigilance at the end of a 12-h shift. We observed a sample of day-shift and night-shift hospital nurses over a 10-day period. At the end of three, consecutive, 12-h shifts (7 pm-7am or 7am-7 pm), participants completed a cognitive battery assessing vigilance, cognitive throughput, and medication calculation fluency (via an investigator developed and tested metric). Night-shift nurses exhibited significantly greater sleep fragmentation as well as a greater disparity between their wake-time and time of CBT minimum compared to day-shift nurses. Night-shift nurses exhibited significantly slower cognitive proficiency at the end of their shifts, even after adjustment for CBT phase. These results suggest that circadian disruption and reduced sleep quality both contribute to cognitive functioning and performance.
Positive Impact of IPS Supported Employment on PTSD-Related Occupational-Psychosocial Functional Outcomes: Results From a VA Randomized-Controlled Trial
(American Psychological Association, 2019) VA CSP 589 VIP-STAR Investigators; US Department of Veterans Affairs; Veterans Health Administration (VHA); San Francisco VA Medical Center; University of California San Francisco; VA Palo Alto Health Care System; James J. Peters VA Medical Center; VA Connecticut Healthcare System; University of Alabama Tuscaloosa; Veterans Affairs Medical Center - Birmingham; VA North Texas Health Care System
Objective: Posttraumatic stress disorder (PTSD) has significant negative effects on occupational, interpersonal, and social functioning. Supported employment is highly effective in helping people with a diagnosis of PTSD obtain and maintain competitive employment. However, less is known about the impact of supported employment on functioning in work or school, social, and interpersonal areas as specifically related to the symptoms of PTSD. Method: The Veterans Individual Placement and Support Toward Advancing Recovery study was a prospective, multisite, randomized, controlled trial that compared Individual Placement and Support (IPS) supported employment with a stepwise vocational rehabilitation involving transitional work (TW) assignments with unemployed veterans with PTSD diagnoses (a = 541) at 12 Veterans Administration (VA) medical centers. This analysis focuses on the PTSD-related functional outcomes over the 18-month follow-up period. Results: Compared with those randomized to TW, the PTSD Related Functioning Inventory (PRFI) total score significantly improved for participants randomized to IPS (ISMeans difference = -3.92, 95% CI [-7.49, -.36]; p = .03) over 18 months. When the Work/School subscale of the PRFI was removed from the analysis, the IPS group continued to show significant improvements compared with the TW group on the PRFI relationship and lifestyle domains (LSMeans difference = -2.37, 95% CI [-4.74_00]; p = .05), suggesting a positive impact of IPS beyond work/school functioning. Conclusion: Compared with the usual-care VA vocational services for veterans with PTSD, IPS supported employment is associated with greater improvement in overall PTSD-related functioning, including occupational, interpersonal, and lifestyle domains. In addition to superior employment outcomes. IPS has a positive impact on occupational-psychosocial functioning outcomes.

Objective: Transitional work (TW) for veterans with psychiatric disabilities is the predominant model of vocational rehabilitation in the Veterans Health Administration (VA). Although, on average, TW employment outcomes have been demonstrated to be inferior to supported employment. little is known about the potential subgroup of veterans for which TW may be most effective. This study of veterans with posttraumatic stress disorder (PTSD) examines differences in competitive employment outcomes and identifies characteristics of veterans who chose to engage in TW compared with those who did not. Method: A post hoc comparative subgroup analysis of veterans with PTSD randomly assigned to TW as part of a randomized controlled trial was conducted. Veterans were divided into 2 subgroups: those who engaged in TW (n = 141) and nonengagers (n = 129). Differences in baseline characteristics were examined and 18-month employment outcomes were compared. Results: There were no differences in 18-month employment outcomes between TW engagers and nonengagers. Compared with TW engagers, those that did not engage in TW were 2.5 times more likely to get a competitive job within the first 6 months and were less likely to obtain lower skilled jobs. Younger age, adequate housing, personal means of transportation, and recent work history factor into the odds of gaining and maintaining competitive work. Conclusions and Implications for Practice: Consistent with past research, engagement in TW did not result in improved long-term competitive employment outcomes for veterans with PTSD. Those who did not engage in TW were more likely to gain a competitive job within the first 6 months.
