Multiple early factors anticipate post-acute COVID-19 sequelae.

Post-acute sequelae of COVID-19 (PASC) represent an emerging global crisis. However, quantifiable risk factors for PASC and their biological associations are poorly resolved. We executed a deep multi-omic, longitudinal investigation of 309 COVID-19 patients from initial diagnosis to convalescence (2-3 months later), integrated with clinical data and patient-reported symptoms. We resolved four PASC-anticipating risk factors at the time of initial COVID-19 diagnosis: type 2 diabetes, SARS-CoV-2 RNAemia, Epstein-Barr virus viremia, and specific auto-antibodies. In patients with gastrointestinal PASC, SARS-CoV-2-specific and CMV-specific CD8+ T cells exhibited unique dynamics during recovery from COVID-19. Analysis of symptom-associated immunological signatures revealed coordinated immunity polarization into four endotypes, exhibiting divergent acute severity and PASC. We find that immunological associations between PASC factors diminish over time, leading to distinct convalescent immune states. Detectability of most PASC factors at COVID-19 diagnosis emphasizes the importance of early disease measurements for understanding emergent chronic conditions and suggests PASC treatment strategies.

Multi-Omics Resolves a Sharp Disease-State Shift between Mild and Moderate COVID-19.

We present an integrated analysis of the clinical measurements, immune cells, and plasma multi-omics of 139 COVID-19 patients representing all levels of disease severity, from serial blood draws collected during the first week of infection following diagnosis. We identify a major shift between mild and moderate disease, at which point elevated inflammatory signaling is accompanied by the loss of specific classes of metabolites and metabolic processes. Within this stressed plasma environment at moderate disease, multiple unusual immune cell phenotypes emerge and amplify with increasing disease severity. We condensed over 120,000 immune features into a single axis to capture how different immune cell classes coordinate in response to SARS-CoV-2. This immune-response axis independently aligns with the major plasma composition changes, with clinical metrics of blood clotting, and with the sharp transition between mild and moderate disease. This study suggests that moderate disease may provide the most effective setting for therapeutic intervention.

The Compassion Club: A New Proposal for Transformation of Tobacco Retail.

INTRODUCTION: One major assumption in the current tobacco industry is the distribution of tobacco products through a system of commercial for-profit retail. However, other models of distribution that do not rely on this mechanism exist. AIMS AND METHODS: In this review, we examine the potential of a nonprofit Compassion Club model and discuss how the current existence of independent vape stores might provide the infrastructure to allow the transformation of tobacco distribution. RESULTS: Compassion Clubs exist internationally with different levels of regulation and legality and have generally been focused on the distribution of illegal drugs or hard-to-access pharmaceuticals. They provide access to drugs for existing users, limit access by novices, limit negative impacts from illicit markets, and provide social support focused on reducing harms associated with drug use. CONCLUSIONS: With decreasing prevalence of tobacco use in many countries and growing interest in a tobacco endgame, a Compassion Club model of distribution could help transition tobacco away from the model of commercial widely available distribution. More work is needed to develop the regulations and policies that might guide a compassion club model. IMPLICATIONS: Compassion clubs are a model for the distribution of psychoactive substances that are focused on harm reduction and social support rather than profit. There has been little discussion about the possibility that this promising model could be applied to help transform the tobacco industry. Many independent vape stores already demonstrate aspects of the compassion club model that could be used to support a transition.

A Pilot Study of the Efficacy of the Unified Protocol for Transdiagnostic Treatment of Emotional Disorders in Treating Posttraumatic Psychopathology: A Randomized Controlled Trial.

The Unified Protocol for Transdiagnostic Treatment of Emotional Disorders (UP) is an intervention that targets common mechanisms that maintain symptoms across multiple disorders. The UP has been shown to be effective across many disorders, including generalized anxiety disorder, major depressive episode (MDE), and panic disorder, that commonly codevelop following trauma exposure. The present study represented the first randomized controlled trial of the UP in the treatment of trauma-related psychopathology, including posttraumatic stress disorder (PTSD), depression, and anxiety symptoms. Adults (N = 43) who developed posttraumatic psychopathology that included PTSD, MDE, or an anxiety disorder after sustaining a severe injury were randomly assigned to receive 10-14 weekly, 60-min sessions of UP (n = 22) or usual care (n = 21). The primary treatment outcome was PTSD symptom severity, with secondary outcomes of depression and anxiety symptom severity and loss of diagnosis for any trauma-related psychiatric disorder. Assessments were conducted at intake, posttreatment, and 6-month follow-up. Posttreatment, participants who received the UP showed significantly larger reductions in PTSD, Hedges' g = 1.27; anxiety, Hedges' g = 1.20; and depression symptom severity, Hedges' g = 1.40, compared to those receiving usual care. These treatment effects were maintained at 6-month follow-up for PTSD, anxiety, and depressive symptom severity. Statistically significant posttreatment loss of PTSD, MDE, and agoraphobia diagnoses was observed for participants who received the UP but not usual care. This study provides preliminary evidence that the UP may be an effective non-trauma-focused treatment for PTSD and other trauma-related psychopathology.

You are at rock bottom: A qualitative systematic review of the needs of bereaved parents as they journey through the death of their child to cancer.

PROBLEM IDENTIFICATION: This systematic review will examine the social support needs of bereaved parents in the specific context of pediatric cancer by synthesizing the qualitative evidence. Social support encompasses emotional, practical, informational, and meaning-making support needs. LITERATURE SEARCH: The Joanna Briggs Institute procedures for conducting qualitative systematic reviews guided every stage of this review. Four databases (PsychInfo, CINAHL, Pubmed, and ASSIA) were systematically searched, in addition to the gray literature and scoping review. Through a five-step critical appraisal process 11 out of 668 potential articles were identified as meeting the inclusion criteria. DATA EVALUATION/SYNTHESIS: Relevant findings were synthesized with a thematic-synthesis approach. Findings, which follow the journey of bereaved parents integrated under the core-category "Needs." This encompasses of four higher-level categories: Last days: Parent needs when caring for their dying child Rest in peace: Parent needs during the child's death Feeling abandoned: Parent needs for contact after the child's death Searching for Meaning: Parents needs when making sense of loss. CONCLUSION: Informational support needs is largely unexplored in academic literature. Staff in the treating-hospital are central in offering bereavement-support to parents, who may otherwise feel that they have lost their second home (hospital) and second family (staff).

Modified Cognitive Behavior Therapy for Severe, Treatment-Resistant Obsessive-Compulsive Disorder in an Adolescent With Autism Spectrum Disorder.

There is a high rate of comorbidity between obsessive-compulsive disorder (OCD) and autism spectrum disorders (ASD). Standard cognitive-behavior therapy (CBT) protocols have been shown to be less effective in treating OCD in young people with ASD than in typically developing youth. This case study describes the treatment of an adolescent boy with severe, treatment-resistant OCD and ASD using a modified CBT approach. Modifications to a standard evidence-based CBT for OCD protocol included extended psychoeducation about anxiety; regular home-based sessions; and increased involvement of systems, including family and school. Multi-informant outcome data indicated significant improvements in OCD symptoms over the course of treatment with gains being maintained over a 12-month follow-up period. These findings demonstrate the potential efficacy of modified CBT for pediatric OCD in the context of ASD.

Complication of a columellar strut in an edentulous patient.

The cartilaginous columellar strut is a well established, commonly used graft in rhinoplasty which provides support and stability to the nasal base. The risk of such a graft is related to grafts designs, whereby the posterior aspect can cause clicking with movement across the anterior nasal spine. We present an additional unusual complication of ill-fitting maxillary dentures in an edentulous patient, previously not reported in the literature. This unique complication should alert facial plastic surgeons to use additional caution when sculpting columellar grafts in edentulous patients in order to avoid potential post-operative complications in this specific patient population.

Endoscopic transnasal septotomy for contralateral orbital apex venous angioma resection and decompression.

Tumors of the orbital apex region are traditionally difficult to approach surgically due to key anatomic structures found in this highly crowded region. We present a case of progressively enlarging orbital apex venous angioma treated with a novel endoscopic transnasal septotomy technique. We highlight the key steps to this approach, as well as specific landmarks necessary to achieve a safe and successful outcome.

Large libraries of single-chain trimer peptide-MHCs enable antigen-specific CD8+ T cell discovery and analysis.

The discovery and characterization of antigen-specific CD8+ T cell clonotypes typically involves the labor-intensive synthesis and construction of peptide-MHC tetramers. We adapt single-chain trimer (SCT) technologies into a high throughput platform for pMHC library generation, showing that hundreds can be rapidly prepared across multiple Class I HLA alleles. We use this platform to explore the impact of peptide and SCT template mutations on protein expression yield, thermal stability, and functionality. SCT libraries were an efficient tool for identifying T cells recognizing commonly reported viral epitopes. We then construct SCT libraries to capture SARS-CoV-2 specific CD8+ T cells from COVID-19 participants and healthy donors. The immunogenicity of these epitopes is validated by functional assays of T cells with cloned TCRs captured using SCT libraries. These technologies should enable the rapid analyses of peptide-based T cell responses across several contexts, including autoimmunity, cancer, or infectious disease.

Integrated analysis of plasma and single immune cells uncovers metabolic changes in individuals with COVID-19.

A better understanding of the metabolic alterations in immune cells during severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection may elucidate the wide diversity of clinical symptoms experienced by individuals with coronavirus disease 2019 (COVID-19). Here, we report the metabolic changes associated with the peripheral immune response of 198 individuals with COVID-19 through an integrated analysis of plasma metabolite and protein levels as well as single-cell multiomics analyses from serial blood draws collected during the first week after clinical diagnosis. We document the emergence of rare but metabolically dominant T cell subpopulations and find that increasing disease severity correlates with a bifurcation of monocytes into two metabolically distinct subsets. This integrated analysis reveals a robust interplay between plasma metabolites and cell-type-specific metabolic reprogramming networks that is associated with disease severity and could predict survival.

Large libraries of single-chain trimer peptide-MHCs enable rapid antigen-specific CD8+ T cell discovery and analysis.

CD8 + cytotoxic T cell responses against viral infection represent a major element of the adaptive immune response. We describe the development of a peptide antigen - major histompatibility complex (pMHC) library representing the full SARS-CoV-2 viral proteome, and comprised of 634 pMHC multimers representing the A*02.01, A*24.02, and B*07.02 HLA alleles, as well as specific antigens associated with the cytomegalovirus (CMV). These libraries were used to capture non-expanded CD8 + T cells from blood samples collected from 64 infected individuals, and then analyzed using single cell RNA-seq. The discovery and characterization of antigen-specific CD8 + T cell clonotypes typically involves the labor-intensive synthesis and construction of peptide-MHC tetramers. We adapted single-chain trimer (SCT) technologies into a high throughput platform for pMHC library generation, showing that hundreds can be rapidly prepared across multiple Class I HLA alleles. We used this platform to explore the impact of peptide and SCT template mutations on protein expression yield, thermal stability, and functionality. SCT libraries were an efficient tool for identifying T cells recognizing commonly reported viral epitopes. We then constructed SCT libraries designed to capture SARS-CoV-2 specific CD8 + T cells from COVID-19 participants and healthy donors. The immunogenicity of these epitopes was validated by functional assays of T cells with cloned TCRs captured using SCT libraries. These technologies should enable the rapid analyses of peptide-based T cell responses across several contexts, including autoimmunity, cancer, or infectious disease.

Reinfection with SARS-CoV-2 and Waning Humoral Immunity: A Case Report.

Recovery from COVID-19 is associated with production of anti-SARS-CoV-2 antibodies, but it is uncertain whether these confer immunity. We describe viral RNA shedding duration in hospitalized patients and identify patients with recurrent shedding. We sequenced viruses from two distinct episodes of symptomatic COVID-19 separated by 144 days in a single patient, to conclusively describe reinfection with a different strain harboring the spike variant D614G. This case of reinfection was one of the first cases of reinfection reported in 2020. With antibody, B cell and T cell analytics, we show correlates of adaptive immunity at reinfection, including a differential response in neutralizing antibodies to a D614G pseudovirus. Finally, we discuss implications for vaccine programs and begin to define benchmarks for protection against reinfection from SARS-CoV-2.

Angiotensin II receptor I auto-antibodies following SARS-CoV-2 infection.

BACKGROUND: Coronavirus disease 2019 (COVID-19) is associated with endothelial activation and coagulopathy, which may be related to pre-existing or infection-induced pro-thrombotic autoantibodies such as those targeting angiotensin II type I receptor (AT1R-Ab). METHODS: We compared prevalence and levels of AT1R-Ab in COVID-19 cases with mild or severe disease to age and sex matched negative controls utilizing multivariate logistic and quantile regression adjusted for comorbidities including hypertension, diabetes, and heart disease. RESULTS: There were trends toward increased prevalence (50% vs. 33%, p = 0.1) and level of AT1R-Ab (median 9.8 vs. 6.1 U/mL, p = 0.06) in all cases versus controls. When considered by COVID-19 disease severity, there was a trend toward increased prevalence of AT1R-Ab (55% vs. 31%, p = 0.07), as well as significantly higher AT1R-Ab levels (median 10.7 vs. 5.9 U/mL, p = 0.03) amongst individuals with mild COVID-19 versus matched controls. In contrast, the prevalence (42% vs. 37%, p = 0.9) and level (both medians 6.7 U/mL, p = 0.9) of AT1R-Ab amongst those with severe COVID-19 did not differ from matched controls. CONCLUSIONS: These findings support an association between COVID-19 and AT1R-Ab, emphasizing that vascular pathology may be present in individuals with mild COVID-19 as well as those with severe disease.

Reinfection with SARS-CoV-2 and Failure of Humoral Immunity: a case report.

Recovery from COVID-19 is associated with production of anti-SARS-CoV-2 antibodies, but it is uncertain whether these confer immunity. We describe viral RNA shedding duration in hospitalized patients and identify patients with recurrent shedding. We sequenced viruses from two distinct episodes of symptomatic COVID-19 separated by 144 days in a single patient, to conclusively describe reinfection with a new strain harboring the spike variant D614G. With antibody and B cell analytics, we show correlates of adaptive immunity, including a differential response to D614G. Finally, we discuss implications for vaccine programs and begin to define benchmarks for protection against reinfection from SARS-CoV-2.

Multiomic Immunophenotyping of COVID-19 Patients Reveals Early Infection Trajectories.

Host immune responses play central roles in controlling SARS-CoV2 infection, yet remain incompletely characterized and understood. Here, we present a comprehensive immune response map spanning 454 proteins and 847 metabolites in plasma integrated with single-cell multi-omic assays of PBMCs in which whole transcriptome, 192 surface proteins, and T and B cell receptor sequence were co-analyzed within the context of clinical measures from 50 COVID19 patient samples. Our study reveals novel cellular subpopulations, such as proliferative exhausted CD8 + and CD4 + T cells, and cytotoxic CD4 + T cells, that may be features of severe COVID-19 infection. We condensed over 1 million immune features into a single immune response axis that independently aligns with many clinical features and is also strongly associated with disease severity. Our study represents an important resource towards understanding the heterogeneous immune responses of COVID-19 patients and may provide key information for informing therapeutic development.

Methods to quantify variable importance: implications for the analysis of noisy ecological data.

Determining the importance of independent variables is of practical relevance to ecologists and managers concerned with allocating limited resources to the management of natural systems. Although techniques that identify explanatory variables having the largest influence on the response variable are needed to design management actions effectively, the use of various indices to evaluate variable importance is poorly understood. Using Monte Carlo simulations, we compared six different indices commonly used to evaluate variable importance; zero-order correlations, partial correlations, semipartial correlations, standardized regression coefficients, Akaike weights, and independent effects. We simulated four scenarios to evaluate the indices under progressively more complex circumstances that included correlation between explanatory variables, as well as a spurious variable that was correlated with other explanatory variables, but not with the dependent variable. No index performed perfectly under all circumstances, but partial correlations and Akaike weights performed poorly in all cases. Zero-order correlations was the only measure that detected the presence of a spurious variable, whereas only independent effects assigned overlap areas correctly once the spurious variable was removed. We therefore recommend using zero-order correlations to eliminate predictor variables with correlations near zero, followed by the use of independent effects to assign overlap areas and rank variable importance.

Executive Function: Cognition and Behaviour in Adults with Autism Spectrum Disorders (ASD).

Studies of executive function (EF) in autism spectrum disorder (ASD) have reported mixed findings. Possible confounds include EF domain assessed and co-occurring neurodevelopmental diagnoses. EF task performance across multiple domains and everyday function of autistic adults (n = 110) was significantly different to age- and IQ-matched controls (n = 31). Although significantly more likely to fall into the clinically impaired range, 35.8% of the ASD group showed no impairment on EF measures. Factor analysis revealed a single unifying EF construct rather than a selective pattern of impairment. Dysexecutive behaviours were frequently reported in the ASD group, unrelated to Autism symptoms, EF task performance or co-occurring conditions. This study suggests autistic adults can experience clinically significant executive function difficulties and co-occuring dysexecutive behaviours that are disabling in everyday life.

Cognitive and affective associations with an ecologically valid test of theory of mind across the lifespan.

OBJECTIVES: Many studies have demonstrated that theory of mind (ToM) ability declines with increasing age. Research has found that ToM-age associations are often mediated by other cognitive abilities particularly executive function. However, older adults rarely complain about real-world ToM difficulties. It has been suggested that older adults may perform better in real-world situations compared with experimental settings. METHOD: We examined performance on the Strange Stories Film Task (SSFT) which has been designed to assess ToM using naturalistic, video scenarios. Sixty adults aged between 17- and 95-years-old completed the SSFT, inhibitory control (Stroop) and working memory (letter-number sequencing) measures, the basic empathy scale (cognitive and affective empathy), and the broad autism phenotype questionnaire. RESULTS: ToM performance correlated significantly with age, whereas performance on a control task did not. Partial correlations and stepwise regression analyses demonstrated that performance on the three SSFT ToM measures was explained by a combination of executive function and empathy measures, with age explaining none of the variance. CONCLUSIONS: Using a naturalistic test of ToM, performance was shown to decline with age for ToM but not control scenarios. Across the lifespan, the variance in ToM performance was explained by cognitive abilities and empathy but not age. Age alone may not influence ToM ability, but may be associated with age-related changes in cognition and social-cognition. (PsycINFO Database Record

A new test of advanced theory of mind: The "Strange Stories Film Task" captures social processing differences in adults with autism spectrum disorders.

Real-life social processing abilities of adults with autism spectrum disorders (ASD) can be hard to capture in lab-based experimental tasks. A novel measure of social cognition, the "Strange Stories Film task' (SSFt), was designed to overcome limitations of available measures in the field. Brief films were made based on the scenarios from the Strange Stories task (Happé) and designed to capture the subtle social-cognitive difficulties observed in ASD adults. Twenty neurotypical adults were recruited to pilot the new measure. A final test set was produced and administered to a group of 20 adults with ASD and 20 matched controls, alongside established social cognition tasks and questionnaire measures of empathy, alexithymia and ASD traits. The SSFt was more effective than existing measures at differentiating the ASD group from the control group. In the ASD group, the SSFt was associated with the Strange Stories task. The SSFt is a potentially useful tool to identify social cognitive dis/abilities in ASD, with preliminary evidence of adequate convergent validity. Future research directions are discussed.

Exploratory tympanotomy revealing incus discontinuity and stapedial otosclerosis as a cause of conductive hearing loss.

OBJECTIVE: To describe a unilateral progressive conductive hearing loss caused by incus discontinuity (without erosion of the long process of the incus), and otosclerosis with fixation of the stapedial footplate. STUDY DESIGN: Case report. SETTING: Department of Otolaryngology, Head and Neck Surgery of the University of Rochester Medical Center, which is a regional tertiary referral center. PATIENT: A 54-year-old woman with multiple otologic complaints including tympanic membrane perforations, otalgia, tinnitus, and hearing loss. Audiography demonstrated 100% speech discrimination bilaterally and a significant conductive right-sided hearing loss. INTERVENTION: The patient underwent a stapedectomy, during which a discontinuity between the long process of the incus and the stapes with no bony erosion was identified. The stapedectomy was completed and an ossicular piston prosthesis was inserted to reestablish ossicular continuity with the tympanic membrane. MAIN OUTCOME MEASURE: Improved subjective hearing confirmed objectively by audiography. CONCLUSION: This is the third reported case of an unusual combination of otosclerosis and ossicular discontinuity, and the first such case report in a patient without head trauma. In addition, it adds a unique item to the differential diagnosis of the pathologic features implicated in an ear with a conductive deficit and normal tympanogram.
