Implementation Barriers and Experiences of Eligible Patients Who Failed to Enroll in Collaborative Care for Depression and Anxiety.

BACKGROUND: Effective and efficient implementation of the Collaborative Care Model (CoCM) for depression and anxiety is imperative for program success. Studies examining barriers to implementation often omit patient perspectives. OBJECTIVES: To explore experiences and attitudes of eligible patients referred to CoCM who declined participation or were unable to be reached, and identify implementation barriers to inform strategies. DESIGN: Convergent mixed-methods study with a survey and interview. PARTICIPANTS: Primary care patients at an academic medical center who were referred to a CoCM program for anxiety and depression by their primary care clinician (PCC) but declined participation or were unable to be reached by the behavioral health care manager to initiate care (n = 80). Interviews were conducted with 45 survey respondents. MAIN MEASURES: Survey of patients' referral experiences and behavioral health preferences as they related to failing to enroll in the program. Interview questions were developed using the Consolidated Framework for Implementation Research version 2.0 (CFIR 2.0) to identify implementation barriers to enrollment. KEY RESULTS: Survey results found that patients were uncertain about insurance coverage, did not understand the program, and felt services were not necessary. Referred patients who declined participation were concerned about how their mental health information would be used and preferred treatment without medication. Men agreed more that they did not need services. Qualitative results exhibited a variety of implementation determinants (n = 23) across the five CFIR 2.0 domains. Barriers included mental health stigma, perceiving behavioral health as outside of primary care practice guidelines, short or infrequent primary care appointments, prioritizing physical health over mental health, receiving inaccurate program information, low motivation to engage, and a less established relationship with their PCC. CONCLUSIONS: Multiple barriers to enrollment led to failing to link patients to care, which can inform implementation strategies to address the patient-reported experiences and concerns.

Community-level prevalence of a forest pathogen, not individual-level disease risk, declines with tree diversity.

Understanding why diversity sometimes limits disease is essential for managing outbreaks; however, mechanisms underlying this 'dilution effect' remain poorly understood. Negative diversity-disease relationships have previously been detected in plant communities impacted by an emerging forest disease, sudden oak death. We used this focal system to empirically evaluate whether these relationships were driven by dilution mechanisms that reduce transmission risk for individuals or from the fact that disease was averaged across the host community. We integrated laboratory competence measurements with plant community and symptom data from a large forest monitoring network. Richness increased disease risk for bay laurel trees, dismissing possible dilution mechanisms. Nonetheless, richness was negatively associated with community-level disease prevalence because the disease was aggregated among hosts that vary in disease susceptibility. Aggregating observations (which is surprisingly common in other dilution effect studies) can lead to misinterpretations of dilution mechanisms and bias towards a negative diversity-disease relationship.

Improving Payment for Collaborative Mental Health Care in Primary Care.

BACKGROUND: There is strong evidence supporting implementation of the Collaborative Care Model within primary care. Fee-for-service payment codes, published by Current Procedural Terminology in 2018, have made collaborative care separately reimbursable for the first time. These codes (ie, 99492-99494) reimburse for time spent per month by any member of the care team engaged in Collaborative Care, including behavioral care managers, primary care providers, and consulting psychiatrists. Time-based billing for these codes presents challenges for providers delivering Collaborative Care services. OBJECTIVES: Based on experience from multiple health care organizations, we reflect on these challenges and provide suggestions for implementation and future refinement of the codes. CONCLUSIONS: Further refinements to the codes are encouraged, including moving from a calendar month to a 30-day reimbursement cycle. In addition, we recommend payers adopt the new code proposed by the Centers for Medicare and Medicaid Services to account for smaller increments of time.

Long-term experience using CNI-free immunosuppression in selected paediatric heart transplant recipients.

BACKGROUND: CNI-free immunosuppression with conversion to mTORi-based immunosuppression has been demonstrated to reduce CNI-toxicity and to exhibit anti-proliferative properties. However, the experience of CNI-free immunosuppression in paediatric heart transplantation is limited. METHODS: A retrospective analysis was conducted of 129 paediatric heart transplants performed between 1997 and 2015. Fifteen patients with clinically indicated conversion from CNI-based to CNI-free immunosuppression were identified. Survival data, rejection episodes, renal function, post-transplantation lymphoproliferative disorder and CAV, including examination with OCT were analysed. RESULTS: Immunosuppression conversion was successful in all patients. Fourteen of 15 patients (93%) are currently living with good graft function. Median post-transplant survival was 15 years (range, 5-23 years), and median follow-up since conversion was 6 years (range, 1-11 years). Mild (grade 1R) ACR was present in three patients after discontinuation of CNIs. The recovery of renal function with a significant increase in eGFR was observed at 1 and 3 years after conversion. No patient had angiographic signs of macroscopic CAV according to the current ISHLT classification; however, OCT showed the signs of angiographically silent CAV in all patients. CAV did not progress in any patient, implying CAV was stabilised by mTORi-based CNI-free immunosuppression. CONCLUSIONS: CNI-free immunosuppression based on mTORis is a safe and appropriate strategy for maintenance therapy in selected paediatric patients, significantly improves renal function and stabilises CAV. OCT revealed early development of angiographically silent CAV.

Sporulation Potential of Phytophthora ramorum Differs Among Common California Plant Species in the Big Sur Region.

Sudden oak death (SOD), caused by the generalist pathogen Phytophthora ramorum, has profoundly impacted California coastal ecosystems. SOD has largely been treated as a two-host system, with Umbellularia californica as the most transmissive host, Notholithocarpus densiflorus less so, and remaining species as epidemiologically unimportant. However, this understanding of transmission potential primarily stems from observational field studies rather than direct measurements on the diverse assemblage of plant species. Here, we formally quantify the sporulation potential of common plant species inhabiting SOD-endemic ecosystems on the California coast in the Big Sur region. This study allows us to better understand the pathogen's basic biology, trajectory of SOD in a changing environment, and how the entire host community contributes to disease risk. Leaves were inoculated in a controlled laboratory environment and assessed for production of sporangia and chlamydospores, the infectious and resistant propagules, respectively. P. ramorum was capable of infecting every species in our study and almost all species produced spores to some extent. Sporangia production was greatest in N. densiflorus and U. californica and the difference was insignificant. Even though other species produced much less, quantities were nonzero. Thus, additional species may play a previously unrecognized role in local transmission. Chlamydospore production was highest in Acer macrophyllum and Ceanothus oliganthus, raising questions about the role they play in pathogen persistence. Lesion size did not consistently correlate with the production of either sporangia or chlamydospores. Overall, we achieved an empirical foundation to better understand how community composition affects transmission of P. ramorum.

Internalizing symptoms, intersectional discrimination, and social support among Asian-Pacific Islander sexual and gender minority adults.

OBJECTIVE: This study examined associations of discrimination, social support, and their interaction, with internalizing symptoms among Asian-Pacific Islander (API) sexual and gender minority (SGM) adults in the U.S. METHOD: Analyses included data from 544 participants who completed an online survey, including measures of three internalizing symptoms (anxiety, depression, and somatization), five forms of discrimination (racism, heterosexism/cisgenderism, and three forms of intersectional discrimination), and two types of social support (acceptance for sexual/gender identity, general social support). RESULTS: All forms of discrimination were positively associated with all internalizing symptoms, with the strongest associations with somatization symptoms; further, acceptance for sexual/gender identity was negatively associated with all internalizing symptoms. Overall social support did not buffer associations of discrimination with internalizing symptoms. Positive associations between discrimination and symptoms were generally stronger at higher social support levels, and social support had weaker negative associations with internalizing symptoms at higher discrimination levels. CONCLUSION: Findings suggest the importance of increasing sexual/gender identity-specific social support, attending to somatization symptoms as an important manifestation of discrimination and reducing societal discrimination to address mental health needs of API SGM adults in the U.S. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

Psychiatric Aspects of Chloroquine and Hydroxychloroquine Treatment in the Wake of Coronavirus Disease-2019: Psychopharmacological Interactions and Neuropsychiatric Sequelae.

BACKGROUND: Chloroquine and hydroxychloroquine are among several experimental treatments being investigated in the urgent response to the coronavirus disease-2019. With increased use of these medications, physicians need to become knowledgeable of these drugs' neuropsychiatric side effects and interactions with psychiatric medications. OBJECTIVE: Clarify evidence base regarding the psychiatric side effects and psychiatric drug interactions of chloroquine and hydroxychloroquine. METHODS: A literature review was performed in PubMed from 1950 to 2020 regarding psychiatric topics and targeted pharmacological properties of chloroquine and hydroxychloroquine. RESULTS: First, chloroquine and hydroxychloroquine may mildly inhibit CYP2D6 metabolism of psychiatric medications, and psychiatric medications that interfere with CYP2D6 or CYP3A4 activity could alter chloroquine and hydroxychloroquine levels. Second, they may prolong the QT interval, warranting caution with concomitant prescription of other QT prolonging agents. Finally, neuropsychiatric side effects are very uncommon but possible and include a potentially prolonged phenomenon of "psychosis after chloroquine." Hydroxychloroquine has less information available about its neuropsychiatric side effects than chloroquine, with psychosis literature limited to several case reports. Weak evidence suggests a possible association of hydroxychloroquine exposure and increased suicidal ideation. It is not clear whether patients with psychiatric illness are more vulnerable to neuropsychiatric sequela of these medications; however, overdose of these medications by suicidal patients has high risk of mortality. CONCLUSION: The risk of neuropsychiatric side effects of chloroquine and hydroxychloroquine when used for coronavirus disease-2019 treatment is not known. Best practice may include suicide risk assessment for patients treated with hydroxychloroquine. However, delirium is expected to be a more likely etiology of neuropsychiatric symptoms in critically ill patients treated for coronavirus disease-2019, and adjustment disorder is a much more likely etiology of anxiety and depression symptoms than the side effects of chloroquine or hydroxychloroquine.

Gendered racism and the sexual and reproductive health of Black and Latina Women.

Objective: To understand health disparities, it is important to use an intersectional framework that examines unique experiences of oppression faced by particular groups due to their intersecting identities and social positions linked to societal structures. We focus on Black and Latina women and their experiences with 'gendered racism' - unique forms of oppression due to the intersection of race/ethnicity and gender - to foster understanding of disparities between Black and Latina versus White women in sexual and reproductive health outcomes in the U.S. Specifically, we focus on stereotype-related gendered racism (ongoing discrimination and stereotype threat based on historically-rooted stereotypes about Black and Latina women's sexuality and motherhood) and birth control-related mistrust (ongoing mistrust of the government and medical system related to birth control due to historical and current abuses).Design: We analyzed data from two survey studies with adult women in New York (Study 1: paper-and-pencil community data collection, N = 135, Mage = 43.35) and across the U.S. (Study 2: online data collection, N = 343, Mage = 29.49) who were currently pregnant or had at least one child and identified as Black, Latina, or White.Results: Black and Latina women reported greater frequency of and concern over stereotype-related gendered racism (F(3,131) = 17.90, p < .001 Study 1; F(3,339) = 22.23, p < .001 Study 2) and greater birth control-related mistrust (F(3,131) = 7.55, p < .001 Study 1; F(3,339) = 17.32, p < .001 Study 2) than White women did. In turn, stereotype-related gendered racism was positively associated with pregnancy-specific stress (ß = .40, p < .001 Study 1; ß = .33, p < .001 Study 2), and birth control-related mistrust was negatively associated with sexual relationship power (ß = -.19, p = .002 Study 2), which are factors known to contribute to birth outcomes and sexual risk, respectively.Conclusion: Findings suggest that gendered racism may play an important role in existing racial/ethnic disparities in women's sexual and reproductive health outcomes, and interventions addressing gendered racism at multiple levels are needed to promote health equity.

Immunodepression after CPB: Cytokine dynamics and clinics after pediatric cardiac surgery - A prospective trial.

BACKGROUND: Corrective surgery for congenital heart defects is known to trigger a severe immune reaction. There has been extensive research on the effects of inflammation after cardiopulmonary bypass (CPB). Interestingly, monocytes are observed to be non-responsive to stimulation with lipopolysaccharide (LPS) under these conditions, indicating a state of immunodepression, which lays the ground for second hit infections after cardiosurgery with CPB. OBJECTIVES: The aim of this prospective study was to analyze immunodepression after pediatric cardiopulmonary bypass and to differentiate the effects of monocytic anergy on postoperative outcome. METHODS: In a prospective trial, we quantified the immune responses in 20 pediatric patients (median age 4.9months, range 2.3-38.2months; median weight 7.2kg, range 5.2-11.7kg) with congenital ventricular septal defect undergoing heart surgery with CPB. Ex vivo LPS-induced protein expression of IFN-γ, IL-1ß, IL-1Ra, IL-6, IL-8, IL-10, IL-12, IL-17, TNF-α, and MCP-1 was measured before (T1), immediately after (T2) and 4h after (T3) cardiopulmonary bypass surgery using Luminex technology. RESULTS: The innate immune system responds to CPB with an almost complete depression of monocytic function. Inflammatory IL-12, TNF-α, IL-1ß, IL-6, IL-8 and IFN-y are completely suppressed. IL-10, IL-1Ra and MCP-1 are still produced during suppression with IL-1Ra being overly secreted during reversion. Suppression of TNF-α expression after LPS-stimulation correlates closely with longer mechanical ventilation time (r=-0.619, p=0.004). CONCLUSION: Cardiosurgery with CPB causes a state of immunodepression making pediatric patients more vulnerable to second hit infections. MCP-1, IL-10, and IL-1Ra play an important role in monocyte recovery, eventually permitting new therapeutic options for controlling immunodepression and inflammation. Standardized glucocorticoid therapy should be evaluated carefully for each individual patient.

First steps to a clinical research unit for developmental research in paediatric cardiology: conception and progress of the LEADER project (Long Term Early Development Research) in CHD.

OBJECTIVE: We developed the Long-term Early Development Research (LEADER) project to investigate the development of children with CHD and/or after cardiopulmonary resuscitation. Both populations are at risk for delays in motor, cognitive, and language development. However, few studies to date have investigated the longitudinal development in these children. METHODS: To establish a clinical research unit, we planned three studies: a cross-sectional study in children after cardiopulmonary resuscitation (LEADER-REA Pilot Study), a longitudinal study in children after cardiopulmonary resuscitation, with a focus on evaluating various biomarkers as predictors for developmental outcome (LEADER-CPR study), and a longitudinal study in children with ventricular septal defect, tetralogy of Fallot, or transposition of the great arteries after cardiac surgery (LEADER-CHD study). RESULTS: Implementation of all three LEADER studies was successful and study protocols were conducted as planned. Findings from the LEADER-REA Pilot study have been recently published and data collection for both prospective trials is ongoing. Descriptive analysis of the first 20 assessments of the LEADER-CHD study showed no severe deficits in overall cognitive, motor, and language developments in the children. CONCLUSIONS: Children with CHD and/or after cardiopulmonary resuscitation are at risk for developmental delay. Therefore, a detailed developmental assessment is necessary as a pre-requisite for individual developmental support. Our LEADER project has been shown to be feasible in a clinical setting and is the first step towards the establishment of a clinical research unit in our clinic with a focus on longitudinal research.

Developmental Outcome in Infants with Cardiovascular Disease After Cardiopulmonary Resuscitation: A Pilot Study.

Unfavorable neurological outcome in children after cardiopulmonary resuscitation in infancy is frequent. However, few studies have investigated the development of these patients using comprehensive developmental tests and the feasibility of the Bayley Scales of Infant Development, 3rd Edition (BSID-III) has not been reported for this population. In this cross-sectional pilot study, we assessed the cognitive, language, and motor development in infants after cardiopulmonary resuscitation of ≥ 5 min with the BSID-III at the age of 12 or 24 months, depending on recruitment age. For analysis, 11 patients with in-hospital (n = 8) and out-of-hospital (n = 3) cardiac arrest were included. BSID-III results could not be quantified in three patients because of visual/hearing and/or motor impairment. In patients with quantifiable scores, 50.0% scored average in composite BSID-III scores, while the other 50.0% showed developmental delays, scoring distinctly below average. We conclude that the BSID-III is feasible for developmental assessment in the majority of the study population, but the use of instruments suitable for hearing/visually impaired and/or severely disabled infants is crucial to avoid biased results. Accurate characterization of developmental deficits is important to facilitate early identification and therapy of deficits.

Pregnancy-specific coping and changes in emotional distress from mid- to late pregnancy.

Objective: To examine whether pregnancy-specific coping predicts changes in emotional distress from mid- to late pregnancy. Background: There is a need to identify ways of coping that reduce or elevate emotional distress in pregnant women as such distress increases the risk of adverse birth outcomes. Methods: 132 women receiving prenatal care from a university hospital midwifery practice were recruited prior to 25 weeks gestation (M = 19.58, SD = 5.14). The state anxiety version of the State-Trait Personality Inventory (STPI) and the Revised Prenatal Distress Questionnaire (NuPDQ) were administered in mid- (M = 25.7 weeks, SD = 4.55) and late (M = 33.4 weeks, SD = 4.18) pregnancy and the Revised Prenatal Coping Inventory (NuPCI) at the latter timepoint. Results: Factor analysis of the NuPCI identified five distinct, conceptually interpretable types of coping: Prayer/Spirituality, Receiving Social Support, Planning/Preparation, Positive Appraisal, and Avoidant Coping. Avoidant Coping was used least frequently and Positive Appraisal was used most. The STPI and NuPDQ were aggregated to create a measure of emotional distress. After controlling for mid-pregnancy distress, Avoidant Coping predicted greater emotional distress in late pregnancy (ß = .18, R2 = .61, p < .01) and Positive Appraisal predicted lower late pregnancy distress (ß = -.15, R2 = .60, p < .01). Conclusion: This is one of the first studies to demonstrate that specific ways of coping with stress during pregnancy predict changes in pregnant women's emotional distress. The NuPCI is a psychometrically sound self-report instrument to examine coping and its association with emotional distress.

Impact and Prevalence of Physical and Verbal Violence Toward Healthcare Workers.

BACKGROUND: Threatening and assaultive behaviors against healthcare workers are a growing national concern.1,2,3 OBJECTIVE: To assess the incidence and impact of aggression against healthcare workers, a safety and quality improvement project was initiated in an academic, tertiary care, urban hospital. METHODS: Through the Northwestern Academy of Quality and Safety Initiatives program, an invitation to complete an online survey was sent to healthcare workers. The survey inquired about prevalence, location, and type of experience of physical or verbal abuse by patients or families. Other goals were: 1) worker knowledge and use of reporting systems, 2) effect on healthcare worker engagement, and 3) report of posttraumatic symptoms. RESULTS: 34.4% of healthcare workers reported any incident of verbal or physical violence in the preceeding 12 months, with 13.5% reporting physical assault. Of those with any incident of physical or verbal violence, 60.2% endorsed at least one posttraumatic symptom, 9.4% missed work, and 30.1% had thoughts about leaving their job or career. The reported impact was the same for physical or verbal incidents. DISCUSSION: Physical and verbal abuse of healthcare workers is prevalent and has a significant impact on employee engagement and posttraumatic spectrum symptoms. These results are based on a cross-sectional survey at one institution and may have a significant selection and response bias. CONCLUSION: Assessment of both verbal and physical aggression against healthcare workers should be standard. Front-line consulting psychiatrists and psychiatric programs for employee wellness could assess and manage this impact.

Dynamics in prevalence of Down syndrome in children with congenital heart disease.

We assessed the dynamics in the prevalence of children with congenital heart disease (CHD) and Down syndrome in Germany with regard to phenotype, severity, and gender. Data from patients with CHD and Down syndrome born between 1980 and 2014 were analyzed, who are registered with the German National Register for Congenital Heart Defects. One thousand six hundred eighteen CHD patients with Down syndrome were identified. The prevalence of children born with both Down syndrome and CHD was constant from 2005 to 2009 but increased from 2010 to 2014. Regarding CHD groups, complex and simple lesions have become more equal since 2005. The number of simple lesions with shunt has a peak prevalence in the period of 2010-2014. Atrioventricular septal defect was the most common CHD phenotype, but temporal changes were found within the group of CHD phenotypes over the observation period. CONCLUSION: Our findings suggest a growing number of CHD and Down syndrome, which may be the result of improved medical management and progress in educational, social, and financial support. This development is noteworthy as it adds new aspects to present discussions in the media and political settings. What is known: • Congenital heart disease is regarded to be the most important clinical phenomenon in children with Down syndrome, due to its significant impact on morbidity and mortality. • New developments in prenatal diagnostic and therapy management of congenital heart disease continue to influence the number of patients diagnosed with congenital heart disease and Down syndrome. What is New: • This study provides essential data giving the first overview of the dynamics in the prevalence of congenital heart disease and Down syndrome over an extended length of time up to 2015 in a large patient cohort, taking recent developments into account. • Our data suggest a growing prevalence of congenital heart disease and Down syndrome, which may be the result of improved medical management for Down syndrome patients and progress in educational, social, and financial support for their families; this development is noteworthy as it adds new aspects to the present discussion in the media and political settings.

Educational level and employment status in adults with congenital heart disease.

Purpose Through this study we aimed to assess the educational level and employment status of adults with CHD in Germany. METHODS: Data were acquired from an online survey carried out in 2015 by the German National Register for Congenital Heart Defects. A total of 1458 adults with CHD participated in the survey (response rate: 37.6%). For 1198 participants, detailed medical information, such as main cardiac diagnosis and information from medical reports, was available. RESULTS: Of the participants surveyed (n=1198), 54.5% (n=653) were female, and the mean age was 30 years. The majority of respondents (59.4%) stated that they had high education levels and that they were currently employed (51.1%). Patients with simple CHD had significantly higher levels of education (p<0.001) and were more likely to be employed (p=0.01) than were patients with complex CHD. CONCLUSIONS: More than half of the participants had high education levels and the majority were employed. The association between CHD and its severity and individuals' educational attainment should be investigated more closely in future studies.

Co-occurrence and hybridization of anther-smut pathogens specialized on Dianthus hosts.

Host specialization has important consequences for the diversification and ecological interactions of obligate pathogens. The anther-smut disease of natural plant populations, caused by Microbotryum fungi, has been characterized by specialized host-pathogen interactions, which contribute in part to the isolation among these numerous fungal species. This study investigated the molecular variation of Microbotryum pathogens within the geographic and host-specific distributions on wild Dianthus species in southern European Alps. In contrast to prior studies on this pathogen genus, a range of overlapping host specificities was observed for four delineated Microbotryum lineages on Dianthus hosts, and their frequent co-occurrence within single-host populations was quantified at local and regional scales. In addition to potential consequences for direct pathogen competition, the sympatry of Microbotryum lineages led to hybridization between them in many populations, and these admixed genotypes suffered significant meiotic sterility. Therefore, this investigation of the anther-smut fungi reveals how variation in the degrees of host specificity can have major implications for ecological interactions and genetic integrity of differentiated pathogen lineages.

Agitation, Delirium, and Cognitive Outcomes in Intracerebral Hemorrhage.

BACKGROUND: Delirium predicts higher long-term cognitive morbidity. We previously identified a cohort of patients with spontaneous intracerebral hemorrhage and delirium and found worse outcomes in health-related quality of life (HRQoL) in the domain of cognitive function. OBJECTIVE: We tested the hypothesis that agitation would have additional prognostic significance on later cognitive function HRQoL. METHODS: Prospective identification of 174 patients with acute intracerebral hemorrhage, measuring stroke severity, agitation, and delirium, with a standardized protocol and measures. HRQoL was assessed using the Neuro-QOL at 28 days, 3 months, and 1 year. Functional outcomes were measured with the modified Rankin Scale. RESULTS: Among the 81 patients with HRQoL follow-up data available, patients who had agitation and delirium had worse cognitive function HRQoL scores at 28 days (T scores for delirium with agitation 20.9 ± 7.3, delirium without agitation 30.4 ± 16.5, agitation without delirium 36.6 ± 17.5, and neither agitated nor delirious 40.3 ± 15.9; p = 0.03) and at 1 year (p = 0.006). The effect persisted in mixed models after correction for severity of neurologic injury, age, and time of assessment (p = 0.0006) and was not associated with medication use, seizures, or infection. CONCLUSIONS: The presence of agitation with delirium in patients with intracerebral hemorrhage may predict higher risk of unfavorable cognitive outcomes up to 1 year later.

Survey of corticioid fungi in North American pinaceous forests reveals hyperdiversity, underpopulated sequence databases, and species that are potentially ectomycorrhizal.

The corticioid fungi are commonly encountered, highly diverse, ecologically important, and understudied. We collected specimens in 60 pine and spruce forests across North America to survey corticioid fungal frequency and distribution and to compile an internal transcribed spacer (ITS) database for the group. Sanger sequences from the ITS region of vouchered specimens were compared with sequences on GenBank and UNITE, and with high-throughput sequence data from soil and roots taken at the same sites. Out of 425 high-quality Sanger sequences from vouchered specimens, we recovered 223 distinct operational taxonomic units (OTUs), the majority of which could not be assigned to species by matching to the BLAST database. Corticioid fungi were found to be hyperdiverse, as supported by the observations that nearly two-thirds of our OTUs were represented by single collections and species estimator curves showed steep slopes with no plateaus. We estimate that 14.8-24.7% of our voucher-based OTUs are likely to be ectomycorrhizal (EM). Corticioid fungi recovered from the soil formed a different community assemblage, with EM taxa accounting for 40.5-58.6% of OTUs. We compared basidioma sequences with EM root tips from our data, GenBank, or UNITE, and with this approach, we reiterate existing speculations that Trechispora stellulata is EM. We found that corticioid fungi have a significant distance-decay pattern, adding to the literature supporting fungi as having geographically structured communities. This study provides a first view of the diversity of this important group across North American pine forests, but much of the biology and taxonomy of these diverse, important, and widespread fungi remains unknown.

Discrimination, Internalized Homonegativity, and Attitudes Toward Children of Same-Sex Parents: Can Secure Attachment Buffer Against Stigma Internalization?

With increasing numbers of same-sex couples raising children in the United States, discriminatory attitudes toward children of same-sex parents (ACSSP) are of increasing concern. As with other forms of stigma and discrimination, lesbian, gay, and bisexual (LGB) individuals are at risk for internalizing these societal attitudes, which can negatively affect parenting-related decisions and behaviors and the mental and physical health of their children. Secure attachment is characterized by positive views of the self as loveable and worthy of care that are understood to develop in early relationships with caregivers. Secure attachment has been associated with positive mental and physical health, including among LGB individuals and couples. This study aimed to test the potential buffering role of secure attachment against stigma internalization by examining associations among secure attachment, discrimination, internalized homonegativity (IH), and ACSSP in an online survey study of 209 U.S. adults in same-sex relationships. Bootstrap analyses supported our hypothesized moderated mediation model, with secure attachment being a buffer. Greater discrimination was indirectly associated with more negative ACSSP through greater IH for individuals with mean or lower levels, but not for individuals with higher than average levels of secure attachment, specifically because among those with higher levels of secure attachment, discrimination was not associated with IH. These findings build on and extend past research, with important implications for future research and clinical work with LGB individuals, same-sex couples, and their families, including potential implementation of interventions targeting attachment security.

Strong phylogeographic co-structure between the anther-smut fungus and its white campion host.

Although congruence between host and pathogen phylogenies has been extensively investigated, the congruence between host and pathogen genetic structures at the within-species level has received little attention. Using an unprecedented and comprehensive collection of associated plant-pathogen samples, we investigated the degree of congruence between the genetic structures across Europe of two evolutionary and ecological model organisms, the anther-smut pathogen Microbotryum lychnidis-dioicae and its host plant Silene latifolia. We demonstrated a significant and particularly strong level of host-pathogen co-structure, with three main genetic clusters displaying highly similar spatial ranges in Western Europe, Eastern Europe and Italy, respectively. Correcting for the geographical component of genetic variation, significant correlations were still found between the genetic distances of anther-smut and host populations. Inoculation experiments suggested plant local adaptation, at the cluster level, for resistance to pathogens. These findings indicate that the pathogen remained isolated in the same fragmented southern refugia as its host plant during the last glaciation, and that little long-distance dispersal has occurred since the recolonization of Europe for either the plant or the pathogen, despite their known ability to travel across continents. This, together with the inoculation results, suggests that coevolutionary and competitive processes may be drivers of host-pathogen co-structure.
