Item does not contain fulltext The vast majority of human genes encode multiple isoforms through alternative splicing, and the temporal and spatial regulation of those isoforms is critical for organismal development and function. The spliceosome, which regulates and executes splicing reactions, is primarily composed of small nuclear ribonucleoproteins (snRNPs) that consist of small nuclear RNAs (snRNAs) and protein subunits. snRNA gene transcription is initiated by the snRNA-activating protein complex (SNAPc). Here, we report ten individuals, from eight families, with bi-allelic, deleterious SNAPC4 variants. SNAPC4 encoded one of the five SNAPc subunits that is critical for DNA binding. Most affected individuals presented with delayed motor development and developmental regression after the first year of life, followed by progressive spasticity that led to gait alterations, paraparesis, and oromotor dysfunction. Most individuals had cerebral, cerebellar, or basal ganglia volume loss by brain MRI. In the available cells from affected individuals, SNAPC4 abundance was decreased compared to unaffected controls, suggesting that the bi-allelic variants affect SNAPC4 accumulation. The depletion of SNAPC4 levels in HeLa cell lines via genomic editing led to decreased snRNA expression and global dysregulation of alternative splicing. Analysis of available fibroblasts from affected individuals showed decreased snRNA expression and global dysregulation of alternative splicing compared to unaffected cells. Altogether, these data suggest that these bi-allelic SNAPC4 variants result in loss of function and underlie the neuroregression and progressive spasticity in these affected individuals.

The U.S. Department of Veterans Affairs (VA) has been training clinicians in its cognitive behavioral therapy for chronic pain (CBT-CP) structured protocol since 2012. The aim of this project was to review patient outcomes to determine the effectiveness of the VA's CBT-CP treatment. From 2012-2018, 1,331 Veterans initiated individual CBT-CP treatment as part of the training program. Patient outcomes were assessed with measures of patient-reported pain intensity, pain catastrophizing, depression, pain interference, and quality of life (physical, psychological, social, and environmental). Mixed models of the effects of time indicated significant changes across pretreatment, midtreatment, and treatment conclusion on all outcomes. There was a large effect size (Cohen's d = 0.78) for pain catastrophizing, and there were medium to large effect sizes (d > 0.60) for worst pain intensity, pain interference, depression, and physical quality of life. Systematic training of therapists and implementation of the VA's CBT-CP protocol yielded significant patient improvements across multiple domains. This offers strong support for the VA's CBT-CP as an effective, safe treatment for Veterans with chronic pain and highlights it as a model to increase the availability of training in standardized, pain-focused, evidence-based, behavioral interventions. The findings suggest that the broad dissemination of such training, including in routine, nonpain specialty settings, would improve patient access to effective, nonpharmacological treatment options in both the public and private sectors.

Childhood exposure to intimate partner violence (IPV) is associated with serious psychological outcomes including increased odds of developing callous-unemotional (CU) traits and behaviors. Recent studies suggest that concomitant exposure to animal cruelty (AC) may increase this risk. However, even under these circumstances, bonds with companion animals may still be a protective factor that buffers the deleterious impact of IPV on child adjustment. This cross-sectional study evaluates whether, and to what extent, the association between exposure to IPV and children’s CU and empathic-prosocial (EP) traits vary as a function of children’s positive engagement with pets and exposure to AC. Participants included 204 children (aged 7–12 years; 57% Latinx) and their maternal caregiver who were recruited from domestic violence agencies in a western US state. We conducted multiple moderation analyses to evaluate each outcome individually (i.e., CU traits, EP traits), adjusting for the effects of child age, gender, and Hispanic ethnicity. Positive engagement with pets significantly moderated the relationship between IPV and CU traits, ∇R = 0.03, F (1, 195) = 7.43, β = –0.17, t(195) = –2.73, p = .007. Specifically, when high levels of positive engagement with pets is present, IPV is negatively associated with CU traits, whereas the reverse was true at low levels of positive engagement with pets. Evidence of moderation by AC was not supported. Our findings suggest that children who form close relationships with their pets in the context of IPV appear to derive important support from these animals; safeguarding the well-being of these animals may be critical to their long-term emotional health.

This qualitative study explores the benefits and risks associated with living with companion animals during the transition to adulthood among 117 sexual and gender minority (SGM) emerging adults living in the U.S. Interviews were transcribed and analyzed using template analysis. Thematic analysis identified several risks (caregiver burden, pets as barriers to relationships, animal-related psychological stress) and benefits (pets as a buffer to stress, pets as social capital, pets as a coping mechanism for mental health, and pets as identity and purpose) associated with living with pets. Our results suggest that pets may influence SGM emerging adult identity development and related wellbeing by facilitating feelings of belongingness, positive self-regard, and purpose; promoting social interactions; and providing emotional support and comfort to cope with stress. However, pets, and their associated care, were also a source of caregiving burden and psychological stress. We discuss practice and policy implications and directions for future research.

Chronic low back pain (cLBP) is a common and highly disabling problem world-wide. Although many treatment options exist, it is unclear how to best sequence the multitude of care options to provide the greatest benefit to patients.The Sequential and Comparative Evaluation of Pain Treatment Effectiveness Response (SCEPTER) trial uses a pragmatic, randomized, stepped design. Enrollment targets 2529 participants from 20 Veterans Affairs (VA) medical centers. Participants with chronic low back pain will first be randomized to one of three options: 1) an internet-based self-management program (Pain EASE); 2) a tailored physical therapy program (Enhanced PT); or 3) continued care with active monitoring (CCAM), a form of usual care. Participants not achieving a 30% or 2-point reduction on the study's primary outcome (Brief Pain Inventory Pain Interference (BPI-PI) subscale), 3 months after beginning treatment may undergo re-randomization in a second step to cognitive behavioral therapy for chronic pain, spinal manipulation therapy, or yoga. Secondary outcomes include pain intensity, back pain-related disability, depression, and others. Participants will be assessed every three months until 12 months after initiating their final trial therapy. Companion economic and implementation analyses are also planned.The SCEPTER trial is currently recruiting and enrolling participants.Trial results will inform treatment decisions for the stepped management of chronic low back pain - a common and disabling condition. Additional analyses will help tailor treatment selection to individual patient characteristics, promote efficient resource use, and identify implementation barriers of interventions.clinicaltrials.gov Identifier: NCT04142177.

This study examines the role of human-animal interaction (HAI) in relations between sexual and gender minority (SGM) stress, personal hardiness, and psychological stress during emerging adulthood. Data for the current sample reflect 136 SGM emerging adults between the ages of 18 to 21 years who reported living with a companion animal in the past year (37.5% racial/ethnic minority, 49.2% transgender or gender -expansive, 98.5% sexual minority). Mediation was tested using structural equation modeling with a bootstrapping approach. We found evidence of an indirect effect of microaggressions on personal hardiness. Specifically, increases in microaggressions were associated with increases in HAI; in turn, increases in HAI were associated with higher levels of personal hardiness. No other statistically significant indirect effects were identified in our model. We discuss the implications of these findings for enhancing community capacity to empower and facilitate successful coping among SGM emerging adults.

Objective Despite empirical support for interdisciplinary pain rehabilitation programs improving functioning and quality of life, access to this treatment approach has decreased dramatically over the last 20 years within the United States but has grown significantly in the Department of Veterans Affairs (VA). Between 2009 and 2019, VA pain rehabilitation programs accredited by the Commission on Accreditation of Rehabilitation Facilities increased 10-fold in the VA, expanding from two to 20. The aim of this collaborative observational evaluation was to examine patient outcomes across a subset of six programs at five sites. Methods Outcomes were assessed using agreed-upon measures of patient-reported pain intensity, pain interference across various domains, pain catastrophizing, and sleep. Results A total of 931 patients enrolled in the selected VA interdisciplinary pain programs, with 84.1% of participants completing the full course of treatment. Overall, all programs showed significant improvements from pretreatment to posttreatment in nearly all patient-reported outcomes. The effect sizes ranged from medium to large. Notably, the results demonstrate that positive outcomes were typical despite differences in structure and resources across programs. Conclusions The adverse impacts of opioid use have highlighted the importance of chronic pain treatment approaches that emphasize team-based care focused on functional improvements. This study represents the first and largest analysis of outcomes across chronic pain rehabilitation programs and demonstrates the need for increased access to similar comprehensive approaches to pain management across the health care system. Further, it suggests that a variety of structures may be effective, encouraging flexibility in adopting this interdisciplinary approach.

Long-term opioid therapy has the potential for serious adverse outcomes and is often used in a vulnerable population. Because adverse effects or failure to maintain benefits is common with long-term use, opioid taper or discontinuation may be indicated in certain patients. Concerns about the adverse individual and population effects of opioids have led to numerous strategies aimed at reductions in prescribing. Although opioid reduction efforts have had generally beneficial effects, there have been unintended consequences. Abrupt reduction or discontinuation has been associated with harms that include serious withdrawal symptoms, psychological distress, self-medicating with illicit substances, uncontrolled pain, and suicide. Key questions remain about when and how to safely reduce or discontinue opioids in different patient populations. Thus, health care professionals who reduce or discontinue long-term opioid therapy require a clear understanding of the associated benefits and risks as well as guidance on the best practices for safe and effective opioid reduction. An interdisciplinary panel of pain clinicians and one patient advocate formulated recommendations on tapering methods and ongoing pain management in primary care with emphasis on patient-centered, integrated, comprehensive treatment models employing a biopsychosocial perspective.

The implementation of evidence-based psychotherapies, including patient-level measures such as penetration and rates of successfully completing a course of therapy, has received increasing attention. While much attention has been paid to the effect of patient-level factors on implementation, relatively little attention has been paid to therapist factors (e.g., professional training, experience). OBJECTIVE: The current study explores therapists’ decisions to offer a particular evidence-based psychotherapy (cognitive behavioral therapy for chronic pain; CBT-CP), whether and how they modify CBT-CP, and the relationship between these decisions and patient completion rates. METHODS: The study utilized survey responses from 141 Veterans Affairs therapists certified in CBT-CP. RESULTS: Therapists reported attempting CBT-CP with a little less than one half of their patients with chronic pain (mean = 48.8%, s.d.=35.7). Therapist were generally split between reporting modifying CBT-CP for either very few or most of their patients. After controlling for therapist characteristics and modification, therapist-reported percentage of patients with attempted CBT-CP was positively associated with completion rates, t (111) = 4.57, p

Objective. Evidence to date, while sparse, suggests that patients taking long-term opioids require special considerations and protections to prevent potential iatrogenic harms from opioid de-prescribing, such as increased pain or suffering. Following this study protocol, the EMPOWER study seeks to address multiple unmet needs of patients with chronic pain who desire to reduce long-term opioid therapy, and provide the clinical evidence on effective methodology. Methods. EMPOWER applies patient-centered methods for voluntary prescription opioid reduction conducted within a comprehensive, multi-state, 3-arm randomized controlled comparative effectiveness study of three study arms (1) group cognitive behavioral therapy for chronic pain; (2) group chronic pain self-management; and (3) usual care (taper only). Specialized electronic data capture systems collect patient reported symptoms and satisfaction data weekly and monthly during the taper, with real-time clinical alerts and electronic feedback loops informing, documenting, and steering needed care actions. Conclusion. The EMPOWER study seeks to provide granular evidence on patient response to voluntary opioid tapering, and will provide evidence to inform clinical systems changes, clinical care, patient satisfaction, and patient outcomes for opioid reduction.

Background Produce-associated outbreaks of Shiga toxin–producing Escherichia coli (STEC) were first identified in 1991. In April 2018, New Jersey and Pennsylvania officials reported a cluster of STEC O157 infections associated with multiple locations of a restaurant chain. The Centers for Disease Control and Prevention (CDC) queried PulseNet, the national laboratory network for foodborne disease surveillance, for additional cases and began a national investigation. Methods A case was defined as an infection between 13 March and 22 August 2018 with 1 of the 22 identified outbreak-associated E. coli O157:H7 or E. coli O61 pulsed-field gel electrophoresis pattern combinations, or with a strain STEC O157 that was closely related to the main outbreak strain by whole-genome sequencing. We conducted epidemiologic and traceback investigations to identify illness subclusters and common sources. A US Food and Drug Administration–led environmental assessment, which tested water, soil, manure, compost, and scat samples, was conducted to evaluate potential sources of STEC contamination. Results We identified 240 case-patients from 37 states; 104 were hospitalized, 28 developed hemolytic uremic syndrome, and 5 died. Of 179 people who were interviewed, 152 (85%) reported consuming romaine lettuce in the week before illness onset. Twenty subclusters were identified. Product traceback from subcluster restaurants identified numerous romaine lettuce distributors and growers; all lettuce originated from the Yuma growing region. Water samples collected from an irrigation canal in the region yielded the outbreak strain of STEC O157. Conclusions We report on the largest multistate leafy greens–linked STEC O157 outbreak in several decades. The investigation highlights the complexities associated with investigating outbreaks involving widespread environmental contamination.

Human-animal interaction (HAI) is associated with positive psychological adjustment. Although these benefits are hypothesized to be most pronounced for individuals who experience adversity and compromised social relationships, such as LGBTQ+ (lesbian, gay, bisexual, transgender, queer, and other sexual/gender minority identities) individuals, this hypothesis has not been tested. The current, cross-sectional study examined whether the strength of the relationship between emotional comfort from companion animals and self-esteem and personal hardiness varies as a function of exposure to LGBTQ+ interpersonal stressors (i.e., victimization, microaggressions). Our sample included 155 LGBTQ+ emerging adults who lived with a dog and/or cat in the past year (Mage = 19.34 years, SD = 1.12 years). To test the hypothesis, we conducted simple and multiple moderation analyses. We found evidence that the magnitude of the association between comfort from companion animals and personal hardiness was greater for those who experienced high levels of interpersonal microaggressions. Similarly, victimization moderated the relation between comfort from companion animals and self-esteem. Including victimization and interpersonal microaggressions in the same model resulted in only one significant interaction effect: the relation between comfort from companion animals and self-esteem was positive at high levels of victimization and negative at low levels of victimization. Our results suggest that among LGBTQ+ emerging adults, the benefits of HAI on self-esteem were only present when high levels of victimization were reported. Future research should continue to examine factors that may influence the benefits and risks associated with HAI to identify for whom and under what circumstances HAI is beneficial.

Human–animal interaction research is growing in popularity and methodological rigor; however, there remains a need for psychometrically validated measures and inclusion of broader populations. This study addressed these gaps by reporting on the psychometric properties of the Comfort from Companion Animals Scale (CCAS) in a sample of sexual and gender minority emerging adults. Participants included 138 emerging adults between the ages of 18–21 years (M = 19.33 years, SD = 1.11; 38.4% racial/ethnic minority) who identified as a gender (48.6%) and/or sexual minority (98.6%) and who reported living with a companion animal in the past year. We utilized the following analytic methods: (a) confirmatory factor analyses to compare the unidimensional structure of the CCAS with the two alternative models, (b) multiple group analyses to test measurement invariance across demographic groups, and (c) structural equation models to evaluate construct validity. Preliminary analysis found that the majority of participants did not endorse the two lowest response options. To conduct invariance testing, we eliminated items 3, 5, and 8 from the CCAS and collapsed the lowest response options. The results of the confirmatory factor analysis supported the use of this revised unidimensional model. We found evidence of measurement invariance across gender identity, sexual orientation, and race/ethnicity groups. Construct validity was supported by comparing the CCAS with factors on the Pet Attachment and Life Impact Scale; the positive association between the CCAS and anxiety are discussed in the context of prior research. Overall, our findings highlight the importance of validating human–animal interaction measures across samples from diverse backgrounds. We recommend that future studies continue to test the CCAS and other measures of human–animal attachment among diverse samples to delineate which aspects of human–animal interaction may be most beneficial in promoting mental health in vulnerable populations.

Introduction: Brief Cognitive Behavioral Therapy for Chronic Pain (Brief CBT-CP) is a biopsychosocial treatment designed to improve access to nonpharmacological pain care in primary care. Results from a clinical demonstration project in Veterans Health Administration (VHA) clinics showed rapid improvement in pain outcomes following Brief CBT-CP treatment in Primary Care Behavioral Health (PCBH). As part of this larger project, the current work aimed to understand patients' perspectives of Brief CBT-CP via a self-report survey completed posttreatment. Method: Thirty-four primary care patients received Brief CBT-CP as part of their usual VHA care and subsequently completed an anonymous survey that included questions regarding treatment modality, intervention content, utility, and satisfaction, as well as global assessment of change in pain-related functioning. Results: Participants reported that Brief CBT-CP content was useful (91%) and that they were satisfied with the intervention overall (89%), including appointment length, frequency of encounters, and comprehensibility of content. On average (M = 4.50, SD = 1.71), participants reported "somewhat better" to "moderately better" pain-related functioning following treatment. Exploratory descriptive analysis indicated that self-reported change in function following treatment may vary by patient characteristics, including gender and opioid use history. Discussion: Patients were receptive to Brief CBT-CP, were satisfied with their experience during treatment, and reported benefit in pain-related functioning after treatment. Further development and evaluation of Brief CBT-CP as a feasible biopsychosocial treatment option for pain in primary care clinics using the PCBH model of integration is warranted.

Neurobeachin (NBEA) was initially identified as a candidate gene for autism. Recently, variants in NBEA have been associated with neurodevelopmental delay and childhood epilepsy. Here, we report on a novel NBEA missense variant (c.5899G > A, p.Gly1967Arg) in the Domain of Unknown Function 1088 (DUF1088) identified in a child enrolled in the Undiagnosed Diseases Network (UDN), who presented with neurodevelopmental delay and seizures. Modeling of this variant in the Caenorhabditis elegans NBEA ortholog, sel-2, indicated that the variant was damaging to in vivo function as evidenced by altered cell fate determination and trafficking of potassium channels in neurons. The variant effect was indistinguishable from that of the reference null mutation suggesting that the variant is a strong hypomorph or a complete loss-of-function. Our experimental data provide strong support for the molecular diagnosis and pathogenicity of the NBEA p.Gly1967Arg variant and the importance of the DUF1088 for NBEA function.

Background Complex II is an essential component of the electron transport chain, linking it with the tricarboxylic acid cycle. Its four subunits are encoded in the nuclear genome, and deleterious variants in these genes, including SDHA (OMIM 600857), are associated with a wide range of symptoms including neurological disease, cardiomyopathy, and neoplasia (paraganglioma‐pheochromocytomas (PGL/PCC), and gastrointestinal stromal tumors). Deleterious variants of SDHA are most frequently associated with Leigh and Leigh‐like syndromes. Methods and Results Here, we describe a case of a 9‐year‐old boy with tremor, nystagmus, hypotonia, developmental delay, significant ataxia, and progressive cerebellar atrophy. He was found to have biallelic variants in SDHA, a known pathogenic variant (c.91C>T (p.R31*)), and a variant of unknown significance (c.454G>A (p.E152K)). Deficient activity of complexes II and III was detected in fibroblasts from the patient consistent with a diagnosis of a respiratory chain disorder. Conclusion We, therefore, consider whether c.454G>A (p.E152K) is, indeed, a pathogenic variant, and what implications it has for family members who carry the same variant., Progressive cerebellar atrophy in a patient with complexes II and III deficiency and SDHA compound heterozygous variants. These variants were considered pathogenic, given respiratory chain findings, and the family was counseled based on the presence of pathogenic variants.

Although cognitive behavioral therapy is an effective intervention for chronic pain, it is a lengthy treatment typically applied only in specialty care settings. The aim of this project was to collect preliminary effectiveness data for Brief Cognitive Behavioral Therapy for Chronic Pain (Brief CBT-CP), an abbreviated, modular form of treatment designed for use in primary care.A clinical demonstration project was conducted in which Brief CBT-CP was delivered to primary care patients by 22 integrated care providers practicing in the Primary Care Behavioral Health model of Veterans Health Administration primary care clinics. Brief measures were used at each appointment to collect patient-reported clinical outcomes.One hundred eighteen patients provided sufficient data for analysis (male, 75%; mean age, 51.4 y). Multilevel modeling suggested that a composite measure of pain intensity and functional limitations showed statistically significant improvements by the third appointment (Cohen's d=0.65). Pain-related self-efficacy outcomes showed a similar pattern of results but of smaller effect size (Cohen's d=0.22). The exploratory analysis identified that Brief CBT-CP modules addressing psychoeducation and goal setting, pacing, and relaxation training were associated with the most significant gains in treatment outcomes.These findings provide early support for the effectiveness of Brief CBT-CP when delivered by providers in every day Primary Care Behavioral Health settings. Results are discussed in relation to the need for additional research regarding the potential value of employing safe, population-based, nonpharmacological approaches to pain management in primary care.

Contains fulltext : 202800.pdf (Publisher’s version ) (Open Access) SMARCC2 (BAF170) is one of the invariable core subunits of the ATP-dependent chromatin remodeling BAF (BRG1-associated factor) complex and plays a crucial role in embryogenesis and corticogenesis. Pathogenic variants in genes encoding other components of the BAF complex have been associated with intellectual disability syndromes. Despite its significant biological role, variants in SMARCC2 have not been directly associated with human disease previously. Using whole-exome sequencing and a web-based gene-matching program, we identified 15 individuals with variable degrees of neurodevelopmental delay and growth retardation harboring one of 13 heterozygous variants in SMARCC2, most of them novel and proven de novo. The clinical presentation overlaps with intellectual disability syndromes associated with other BAF subunits, such as Coffin-Siris and Nicolaides-Baraitser syndromes and includes prominent speech impairment, hypotonia, feeding difficulties, behavioral abnormalities, and dysmorphic features such as hypertrichosis, thick eyebrows, thin upper lip vermilion, and upturned nose. Nine out of the fifteen individuals harbor variants in the highly conserved SMARCC2 DNA-interacting domains (SANT and SWIRM) and present with a more severe phenotype. Two of these individuals present cardiac abnormalities. Transcriptomic analysis of fibroblasts from affected individuals highlights a group of differentially expressed genes with possible roles in regulation of neuronal development and function, namely H19, SCRG1, RELN, and CACNB4. Our findings suggest a novel SMARCC2-related syndrome that overlaps with neurodevelopmental disorders associated with variants in BAF-complex subunits.

We report a specific region of Giardia spp. 18S ribosomal RNA (18S rDNA) that serves as an ideal target for quantitative PCR (qPCR) detection and sequencing to identify Giardia species, including the clinically-relevant G. duodenalis , in clinical and environmental samples. The presence of multiple copies of the 18S rDNA gene and variations in the selected 18S genomic region enabled the development of a rapid, sensitive qPCR screening method for the detection of Giardia spp. The analytical sensitivity of the Giardia qPCR assay was determined to be a cyst equivalent of 0.4 G. duodenalis cysts per PCR reaction. Amplicon sequencing of the PCR product confirmed Giardia spp. detection and among the 35 sequences obtained, 31, 3 and 1 isolates were classified as belonging to G. duodenalis, G. microti and G. muris , respectively. The TaqMan assay reported here may be useful for the detection of low levels of Giardia in clinical and environmental samples, and further enables the effective use of direct sequencing of the PCR product for Giardia confirmation and to identify major species of Giardia, including G. duodenalis.

Simple Summary The COVID-19 pandemic has contributed to elevated rates of mental health problems and distress among the U.S. population. Pets may be an important source of social support to combat social isolation. This cross-sectional study used latent profile analysis to identify subgroups of U.S. pet owners based on their perceived mental health symptoms prior to and after the onset of the pandemic. Latent transition analysis was used to determine the stability of subgroup membership and examine the effect of attachment to pets on transition probabilities. Five subgroups were identified: low symptoms, mild symptoms, moderate symptoms, high symptoms, and severe symptoms. Evidence of moderation was found, X2(16) = 41.47, p = 0.04. Specifically, results indicated that attachment to pets functioned as a protective factor for individuals exhibiting moderate and high levels of mental health symptoms, as above average attachment to pets was associated with greater odds of transitioning to a less severe symptom profile. However, individuals with severe symptom profiles and high attachment to pets fared worst in the context of COVID-19 restrictions. This study has important implications for future research investigating the role of pets on mental health and for those providing services to pet owners during the COVID-19 pandemic. Abstract This cross-sectional study examined whether, and to what extent, attachment to pets was associated with changes in latent patterns of adults’ perceived mental health symptoms during the COVID-19 pandemic (n = 1942). We used latent transition analysis to determine the stability of subgroup membership pre- and post-COVID and the effect of attachment to pets on transition probabilities. Mental health before COVID-19 was measured retrospectively. Five subgroups were identified: low symptoms, mild symptoms, moderate symptoms, high symptoms, and severe symptoms. Among individuals in the moderate and high symptoms subgroups, those who reported high attachment to pets generally had greater odds of transitioning to a less severe symptom profile (OR = 2.12) over time than those with low attachment to pets (OR = 1.39). However, those who had a severe symptom profile and high attachment to pets had lower odds of transitioning to a less severe symptom profile (OR = 0.30) and higher odds of maintaining a severe symptom profile (OR = 3.33) than those with low attachment to pets. These findings suggest that the protective and risk effects of attachment to pets differ based on individuals’ psychological symptom patterns across multiple indicators. We discuss the implications of these findings for research, policy, and practice.

It is imperative to understand the behavior of enveloped viruses during water treatment to better protect public health, especially in the light of evidence of detection of coronaviruses in wastewater. We report bench-scale experiments evaluating the extent and mechanisms of removal and/or inactivation of a coronavirus surrogate (ϕ6 bacteriophage) in water by conventional FeCl3 coagulation and Fe(0) electrocoagulation. Both coagulation methods achieved ∼5-log removal/inactivation of ϕ6 in 20 min. Enhanced removal was attributed to the high hydrophobicity of ϕ6 imparted by its characteristic phospholipid envelope. ϕ6 adhesion to freshly precipitated iron (hydr)oxide also led to envelope damage causing inactivation in both coagulation techniques. Fourier transform infrared spectroscopy revealed oxidative damages to ϕ6 lipids only for electrocoagulation consistent with electro-Fenton reactions. Monitoring ϕ6 dsRNA by a novel reverse transcription quantitative polymerase chain reaction (RT-qPCR) method quantified significantly lower viral removal/inactivation in water compared with the plaque assay demonstrating that relying solely on RT-qPCR assays may overstate human health risks arising from viruses. Transmission electron microscopy and computationally generated electron density maps of ϕ6 showed severe morphological damages to virus' envelope and loss of capsid volume accompanying coagulation. Both conventional and electro- coagulation appear to be highly effective in controlling enveloped viruses during surface water treatment.
