Untangling the relationships between age, gender, type of sport, perfectionistic self-presentation and motivation on body satisfaction: a cross-sectional study on aesthetic and non-aesthetic female and male athletes aged 10 to 22 years.

Objectives: To explore the relationships between age, gender, type of sport, perfectionistic self-presentation and motivation on body satisfaction among young athletes in one aesthetic sport (gymnastics) and one non-aesthetic sport (basketball). The study hypothesise that (1) age, gender and type of sport (aesthetic or non-aesthetic) will predict body satisfaction scores, (2) autonomous motivation will positively be related to body satisfaction and (3) perfectionistic self-presentation will negatively be related to body satisfaction. Design: Cross-sectional. Method: 209 athletes (132 gymnasts and 77 basketball players) aged 10-22 (median=13) years were recruited. After data screening, 200 athletes were included in analyses (females: n=155; males: n=45). Participants completed an online survey, which assessed demographic information, athlete motivation (Behavioural Regulation in Sport Questionnaire), perfectionistic self-presentation (Perfectionistic Self-Presentation Scale-Junior Form) and body satisfaction (Body Appreciation Scale-2). Results: Hierarchical multiple regression showed age, self-assigned gender, and two facets of perfectionistic self-presentation (ie, perfectionistic presentation and non-disclosure of imperfection) to predict reported levels of body satisfaction significantly. Subsequently, adding motivational variables did not improve the model. A moderation analysis showed that the relationship between non-disclosure of imperfection and body satisfaction was significantly moderated by gender. Conclusions: Two facets of perfectionistic self-presentation were associated with reported body satisfaction. Additionally, the relationship between non-disclosure of imperfection and body satisfaction appears to differ between female and male athletes. Researchers should move beyond sport types and identify factors (eg, perfectionistic self-presentation) at the individual and environmental levels that can protect young athletes' body satisfaction.

The Effectiveness of Lived Experience Involvement in Eating Disorder Treatment: A Systematic Review.

Objective: This systematic review sought to understand the effectiveness of lived experience mentoring, by people recovered from an eating disorder, with clinical samples currently receiving eating disorder treatment. Methods: The systematic review was conducted using PsycINFO, MEDLINE, Scopus, and ProQuest Dissertations and Theses Global and reviewing reference lists of included papers. Articles were included if they: (1) were intervention studies that included peer (recovered from an eating disorder) involvement, (2) delivered the intervention to clinical samples (or carers with direct involvement in treatment), (3) were in English, and (4) included quantitative results. Results: Eleven studies were included across randomized control trials (RCTs), case series, and a case study; there was variation in quality. Findings varied considerably with some concluding that lived experience mentoring led to significant improvements for mentees, while other studies found no significant differences. Mentor outcomes were often not evaluated. Of those that did assess mentors, there is preliminary evidence for some benefits to participation but also the potential for harm. Discussion: There is a need for further research in this area using high-quality RCTs that address the risk of bias. It is important that lived experience peer mentors are monitored on key outcomes, provided with adequate training and ongoing supervision, and are reimbursed for their involvement. Public Significance: This systematic review is the first review to focus on the use of peer mentors recovered from an eating disorder contributing to interventions for people receiving treatment for an eating disorder. All included studies present quantitative results. Given the emerging interest of lived experience mentoring, understanding its effectiveness for both mentees and impacts on mentors continues to be of critical importance. Resumen. Objetivo: Esta revisión sistemática buscó comprender la efectividad de la consejería de la experiencia vivida por parte de personas recuperadas de un trastorno de la conducta alimentaria, con muestras clínicas que actualmente reciben tratamiento para el trastorno alimentario. Método: La revisión sistemática se realizó utilizando PsycINFO, MEDLINE, Scopus y ProQuest Dissertations, and Theses Global y revisando las listas de referencias de los artículos incluidos. Los artículos se incluyeron si: (1) eran estudios de intervención que incluían la participación de pares (recuperados de un trastorno de la conducta alimentaria), (2) administraban la intervención a muestras clínicas (o cuidadores con participación directa en el tratamiento), (3) estaban en inglés y (4) incluían resultados cuantitativos. Resultados: Se incluyeron once estudios en ensayos controlados aleatorios (ECA), series de casos y un estudio de caso; hubo variación en la calidad. Los hallazgos variaron considerablemente y algunos concluyeron que la consejería de la experiencia vivida condujo a mejoras significativas para los aprendices, mientras que otros estudios no encontraron diferencias significativas. Los resultados del mentor a menudo no se evaluaron. De los que evaluaron a los mentores, hay evidencia preliminar de algunos beneficios de la participación, pero también del potencial de daño. Discusión: Se necesitan estudios de investigación adicionales en esta área que utilicen ECA de alta calidad que aborden el riesgo de sesgo. Es importante que los mentores de pares de la experiencia vivida sean monitoreados en los resultados clave, provistos de capacitación adecuada y supervisión continua, y sean remunerados por su participación.Reprinted from Int J Eat Disord 2023; 56:331-349, with permission from Wiley.

Conofolidine: A Natural Plant Alkaloid That Causes Apoptosis and Senescence in Cancer Cells.

Natural products contribute substantially to anticancer therapy; the plant kingdom provides an important source of molecules. Conofolidine is a novel Aspidosperma-Aspidosperma bisindole alkaloid isolated from the Malayan plant Tabernaemontana corymbosa. Herein, we report conofolidine's broad-spectrum anticancer activity together with that of three other bisindoles-conophylline, leucophyllidine, and bipleiophylline-against human-derived breast, colorectal, pancreatic, and lung carcinoma cell lines. Remarkably, conofolidine was able to induce apoptosis (e.g., in MDA-MB-468 breast) or senescence (e.g., in HT-29 colorectal) in cancer cells. Annexin V-FITC/PI, caspase activation, and PARP cleavage confirmed the former while positive ß-gal staining corroborated the latter. Cell cycle perturbations were evident, comprising S-phase depletion, accompanied by downregulated CDK2, and cyclins (A2, D1) with p21 upregulation. Confocal imaging of HCT-116 cells revealed an induction of aberrant mitotic phenotypes-membrane blebbing, DNA-fragmentation with occasional multi-nucleation. DNA integrity assessment in HCT-116, MDA-MB-468, MIAPaCa-2, and HT-29 cells showed increased fluorescent γ-H2AX during the G1 cell cycle phase; γ-H2AX foci were validated in HCT-116 and MDA-MB-468 cells by confocal microscopy. Conofolidine increased oxidative stress, preceding apoptosis- and senescence-induction in most carcinoma cell lines as seen by enhanced ROS levels accompanied by increased NQO1 expression. Collectively, we present conofolidine as a putative potent anticancer agent capable of inducing heterogeneous modes of cancerous cell death in vitro, encouraging further preclinical evaluations of this natural product.

A guide for self-help guides: best practice implementation.

Guided self-help is an evidence-based intervention used globally. Self-help is a fundamental part of the stepped care model of mental health services that enables the efficient use of limited resources. Despite its importance, there is little information defining the role of the guide and the key competences required. In this context, the guide is defined as the person who facilitates and supports the use self-help materials. This article sets out the role of the guide in guided self-help. It considers practical issues such as the importance of engagement to motivate clients for early change, personalising the intervention, structuring sessions, how best to use routine outcome monitoring and supervision requirements. Key competences are proposed, including generic competences to build the relationship as well as specific competences such as being able to clearly convey the role of the guide to clients. Guides should be prepared for "self-help drift", a concept akin to therapist drift in more traditional therapies. Knowing how to identify mental health problems, use supervision and manage risk and comorbidity are all key requirements for guides. The paper concludes by calling for increased recognition and value of the role of the guide within mental health services.

The potential value of brief waitlist interventions in enhancing treatment retention and outcomes: a randomised controlled trial.

People with eating disorders are often placed on lengthy waitlists for treatment. This is problematic, as increased time spent on waitlists has been shown to predict dropout. We examined whether providing brief interventions to people on a waitlist improved retention or outcomes in treatment. Participants (N = 85) were referred to a university training clinic for 10-session cognitive behavioural therapy for non-underweight patients with eating disorders (CBT-T). While waitlisted for CBT-T, participants were randomised to one of two waitlist interventions or a control condition. In one waitlist intervention (CRT-Brief), participants received a cognitive remediation therapy session at the start of the waitlist period. In the other waitlist intervention (brief contact), participants were sent a short supportive email and psychoeducation halfway through the waitlist period. The control condition was waitlist as usual. There was no evidence to suggest that the waitlist interventions improved symptoms during the waitlist period or CBT-T. However, participants who received a waitlist intervention were three times more likely to complete treatment. The present study suggests that providing even brief contact while people are waitlisted for eating disorder treatment significantly improves retention. However, replication in a more adequately powered study is required.

Encapsulation of copper phenanthroline within horse spleen apoferritin: characterisation, cytotoxic activity and ability to retain temozolomide.

Protein capsules are promising drug delivery vehicles for cancer research therapies. Apoferritin (AFt) is a self-assembling 12 nm diameter hollow nanocage with many desirable features for drug delivery, however, control of drug retention inside the protein cage remains challenging. Here we report the encapsulation of copper(ii)-1,10-phenanthroline (Cu(phen)) within the horse spleen AFt (HSAFt) nanocage, by diffusion of the metal through the pores between the protein subunits. Transmission electron microscopy revealed the formation of organised copper adducts inside HSAFt, without affecting protein integrity. These structures proved stable during storage (>4 months at -20 °C). Exposure to physiologically relevant conditions (37 °C) showed some selectivity in cargo release after 24 h at pH 5.5, relevant to the internalisation of AFt within the endosome (60% release), compared to pH 7.4, relevant to the bloodstream (40% release). Co-encapsulation of temozolomide, a prodrug used to treat glioblastoma multiforme, and Cu(phen) enabled entrapment of an average of 339 TMZ molecules per cage. In vitro results from MTT and clonogenic assays identified cytotoxic activity of the Cu(phen), HSAFt-Cu(phen) and HSAFt-Cu(phen)-TMZ adducts against colorectal cancer cells (HCT-116) and glioblastoma cells (U373V, U373M). However, the presence of the metal also contributed to more potent activity toward healthy MRC5 fibroblasts, a result that requires further investigation to assess the clinical viability of this system.

Negevirus Piura Suppresses Zika Virus Replication in Mosquito Cells.

We investigated the interaction between the insect-specific virus, Piura virus (PIUV), and the arbovirus Zika virus (ZIKV) in Aedes albopictus cells. We performed coinfection experiments in C6/36 cells. Piura virus (Cor 33 strain, Colombia) and ZIKV (PRVABC58 strain, Puerto Rico) were co-inoculated into C6/36 cells using two multiplicity of infection (MOI) combinations: 0.1 for both viruses and 1.0 for ZIKV, 0.1 for PIUV. Wells were infected in triplicate with either PIUV and ZIKV coinfection, ZIKV-only, or PIUV-only. Mock infected cells served as control wells. The cell suspension was collected daily 7 days post-infection. Zika virus load was titrated by TCID50 on Vero 76 cells. The ZIKV-only infection and PIUV and ZIKV coinfection experiments were also quantified by RT-qPCR. We also investigated whether ZIKV interfered in the PIUV replication. PIUV suppressed the replication of ZIKV, resulting in a 10,000-fold reduction in ZIKV titers within 3 days post-infection. PIUV viral loads were not reduced in the presence of ZIKV. We conclude that, when concurrently infected, PIUV suppresses ZIKV in C6/36 cells while ZIKV does not interfere in PIUV replication.

mTBI evaluation, management, and referral to allied healthcare: practices of first-line healthcare professionals.

PRIMARY OBJECTIVE: To gain an understanding of current evaluation practices, post-injury recommendations, and referrals to allied healthcare professions (AHP) by first-line healthcare professionals (FHPs) providing care for people with mild traumatic brain injury (mTBI). RESEARCH DESIGN: Survey study. METHODS AND PROCEDURES: Physicians, physician assistants, nurse practitioners, nurses, and athletic trainers (n = 126) completed an online survey, including Likert scale and free response question relating to mTBI evaluation, management, and referral practices. MAIN OUTCOMES AND RESULTS: FHPs surveyed reported being confident in their ability to evaluate patients with suspected mTBI, relying most heavily on patient-reported symptoms and physical signs as methods of evaluation. Most FHPs reported making recommendations to compensate for the symptoms experienced following mTBI diagnosis. In contrast, FHPs expressed challenges in the evaluation and management of symptoms associated with mTBI along with limited knowledge of and referrals to AHPs. CONCLUSIONS: Overall, FHPs feel confident in the diagnosis of mTBI but experience assessment and management challenges. AHPs are underutilized on mTBI management teams calling for a need for multidisciplinary collaboration on research, education, and rehabilitation efforts to optimally care for people experiencing mTBI symptoms.

Addressing the gap of early intervention for eating disorders in primary health care.

AIM: Only one in four individuals with eating disorders (EDs) seek help, with many barriers to treatment-seeking present. Placing an early intervention model in primary mental health care settings is one approach to reducing these barriers. To date, only one model (emerge-ED) has been evaluated in the literature. METHODS: We aimed to replicate findings from the initial emerge-ED evaluation. We report on treatment outcomes in a new cohort and their views on barriers to treatment-seeking. We then examine how this early intervention model in primary health care has evolved to overcome the barriers to treatment delivery cited by health professionals in the initial evaluation. RESULTS: Eighty participants commenced treatment between July 2020 and March 2022 and completed a mean of 8.98 sessions, 70 (87.5%) completed >1 sessional measure on ED cognitions and behaviours, but only 31% (n = 24) completed lengthier assessments. Findings replicated initial emerge-ED outcomes, with small to moderate effect size decreases in the ED sessional measure at 70 days since treatment commencement for cognitions (d = .63) and ED behaviours (d = .09., .69). The most cited barrier by participants was "belief that my problem is not bad enough", reflective of denial of illness. Lastly, to overcome barriers to treatment delivery clinicians had to deviate from treatment protocols and work collaboratively with other healthcare providers. CONCLUSIONS: Our findings replicated the initial emerge-ED evaluation and highlight the importance of considering primary health care settings as an essential site in delivering early intervention services for EDs.

Mercury bioaccumulation and Hepatozoon spp. infections in two syntopic watersnakes in South Carolina.

Mercury (Hg) is a ubiquitous environmental contaminant known to bioaccumulate in biota and biomagnify in food webs. Parasites occur in nearly every ecosystem and often interact in complex ways with other stressors that their hosts experience. Hepatozoon spp. are intraerythrocytic parasites common in snakes. The Florida green watersnake (Nerodia floridana) and the banded watersnake (Nerodia fasciata) occur syntopically in certain aquatic habitats in the Southeastern United States. The purpose of this study was to investigate relationships among total mercury (THg) concentrations, body size, species, habitat type and prevalence and parasitemia of Hepatozoon spp. infections in snakes. In the present study, we sampled N. floridana and N. fasciata from former nuclear cooling reservoirs and isolated wetlands of the Savannah River Site in South Carolina. We used snake tail clips to quantify THg and collected blood samples for hemoparasite counts. Our results indicate a significant, positive relationship between THg and snake body size in N. floridana and N. fasciata in both habitats. Average THg was significantly higher for N. fasciata compared to N. floridana in bays (0.22 ± 0.02 and 0.08 ± 0.006 mg/kg, respectively; p < 0.01), but not in reservoirs (0.17 ± 0.02 and 0.17 ± 0.03 mg/kg, respectively; p = 0.29). Sex did not appear to be related to THg concentration or Hepatozoon spp. infections in either species. We found no association between Hg and Hepatozoon spp. prevalence or parasitemia; however, our results suggest that species and habitat type play a role in susceptibility to Hepatozoon spp. infection.

A randomised controlled evaluation of an online perfectionism intervention for people with disordered eating - how perfect does it need to be?

Less help-seeking for an eating disorder is predicted by higher levels of denial of, and failure to perceive, illness severity. This research evaluates a "backdoor" approach to early intervention by investigating whether internet cognitive behaviour therapy for perfectionism can significantly improve disordered eating. Additionally, we investigated whether a more interactive intervention impacted outcomes. Participants were recruited worldwide online; 368 were screened, 172 (46.7%) met inclusion criteria (endorsed high shape, weight, or eating concerns) and randomised to an interactive (Focused Minds Program; FMP) or static PDF intervention (Centre for Clinical Intervention; CCI-P) or waitlisted (control condition). Participants completed assessments on disordered eating, perfectionism, and a range of secondary variables at the end of treatment, and 1- and 3-month follow-up. Intent-to-treat analyses indicated that, compared to control, FMP resulted in significantly lower levels of disordered eating at each assessment and CCI-P at the 1- and 3-month follow-up (respective 3-month follow-up between group effect sizes of 0.78 and 0.54). There were no significant differences between the two active interventions on any measure except depression and hated self. Results suggest an alternative approach to directly tackling disordered eating that is low-cost is effective, with a more interactive intervention producing a more rapid effect.Trials Registration: Australian New Zealand Clinical Trials Registry (ANZCTR) Trial Number: ACTRN12621001448831.

A meta-analysis of disordered eating and its association with self-criticism and self-compassion.

OBJECTIVE: Future treatments for eating disorders (ED) need to be enhanced by targeting maintaining mechanisms. Literature suggests self-criticism and self-critical perfectionism act as key mechanisms exacerbating ED, and self-compassion protects against self-criticism. This meta-analysis examines associations between self-criticism and self-critical perfectionism on disordered eating (DE), and reviews how self-compassion and self-criticism relate to each other with respect to DE. METHOD: Searches across three databases yielded 135 studies across 42,952 participants. Heterogeneity, publication bias, and quality assessments were analyzed. Moderation analyses between self-criticism measures, self-compassion measures, between clinical and nonclinical samples, and between cross-sectional and experimental studies were also conducted. RESULTS: Random-effects models showed a medium positive link between self-criticism and DE (r = .37), and 10 subgroups pertaining to various measures of self-criticism utilized in literature showed small to large positive links with DE (r = .20-.52). Preliminary evidence also suggests negative relationships between self-compassion and DE (r = -.40 to -.43) and negative relationships between self-compassion and self-criticism (r = -.04 to -.88). DISCUSSION: Greater levels of self-criticism is linked with greater levels of DE and reduced levels of self-compassion, suggesting a need to tackle self-criticism and nurture self-compassion in standard treatments for ED. Understanding these interactions better in conjunction with dismantling intervention studies can help develop more effective and efficient interventions targeting self-criticism and self-compassion for people with DE. PUBLIC SIGNIFICANCE STATEMENT: Higher levels of self-criticism are linked with higher levels of DE and lower self-compassion. Self-compassion interventions could be more effective and efficient in reducing ED symptoms if self-criticism is tackled early in such treatments.

OBJETIVO: Los futuros tratamientos para los trastornos de la conducta alimentaria (TCA) deben ser mejorados mediante la focalización en los mecanismos de mantenimiento. La literatura sugiere que la autocrítica y el perfeccionismo autocrítico actúan como mecanismos clave que exacerban los TCA, y que la autocompasión protege contra la autocrítica. Este meta-análisis examina las asociaciones entre la autocrítica y el perfeccionismo autocrítico en la alimentación disfuncional (AD), y revisa cómo la autocompasión y la autocrítica se relacionan entre sí con respecto a la AD. MÉTODO: Las búsquedas en tres bases de datos arrojaron 135 estudios con 42,952 participantes. Se analizaron la heterogeneidad, el sesgo de publicación y las evaluaciones de calidad. También se llevaron a cabo análisis de moderación entre las medidas de autocrítica, las medidas de autocompasión, entre muestras clínicas y no clínicas, y entre estudios transversales y experimentales. RESULTADOS: Los modelos de efectos aleatorios mostraron una asociación positiva media entre la autocrítica y la AD (r = .37), y 10 subgrupos relacionados con diversas medidas de autocrítica utilizadas en la literatura mostraron asociaciones positivas pequeñas a grandes con la AD (r = .20-.52). Además, evidencia preliminar sugiere relaciones negativas entre la autocompasión y la AD (r = −0.40-−0.43) y relaciones negativas entre la autocompasión y la autocrítica (r = −.04-−.88). DISCUSIÓN: Los niveles mayores de autocrítica están relacionados con mayores niveles de AD y niveles reducidos de autocompasión, lo que sugiere la necesidad de abordar la autocrítica y fomentar la autocompasión en los tratamientos estándar para los TCA. Comprender mejor estas interacciones en conjunto con estudios de intervención puede ayudar a desarrollar intervenciones más efectivas y eficientes dirigidas a la autocrítica y la autocompasión para personas con AD.

Association of size, climatic factors, and mercury body burdens with movement behavior in American alligators.

Animal movement behavior provides insight into organismal and ecological function. These functions are often disturbed by anthropogenic influences, such as urbanization and habitat fragmentation, yet the effects of long-term exposures to environmental contaminants on movement have yet to be examined. The long lifespans and broad diets of crocodilians often lead to bioaccumulation of persistent contaminants and confer a marked vulnerability to consequent physiological effects. In this study, we investigate the relationships between blood concentrations of mercury (Hg), a widespread contaminant with well characterized neurotoxicity, and movement patterns in free living, naturally exposed American alligators (Alligator mississippiensis). We sampled adult male alligators from two former nuclear cooling reservoirs with different Hg contamination histories and placed GPS transmitters on a subset of individuals from each reservoir (13 total). Data collected over the ensuing two years were analyzed using a linear mixed effects framework combined with AICc model selection to resolve the relationships linking seasonal alligator movement (daily activity (s) and daily distance (m)) and home range to climate conditions, individual traits, and blood Hg concentrations (mg/kg; wet weight). We found that climate conditions, alligator size (snout-vent-length), and blood Hg concentrations all influence alligator daily activity but do not contribute to alligator daily movement (distance). Furthermore, we found that blood Hg concentrations were strongly correlated with seasonal home range size where individuals with elevated Hg had larger home ranges in spring, fall, and winter. These findings provide insight into how climate, anthropogenic contaminants, and individual traits relate to alligator movement patterns across seasons.

Probing the Mechanism of Action of Bis(phenolato) Amine (ONO Donor Set) Titanium(IV) Anticancer Agents.

The need for anticancer therapies that overcome metallodrug resistance while minimizing adverse toxicities is targeted, herein, using titanium coordination complexes. Octahedral titanium(IV) trans,mer-[Ti{R1N(CH2-2-MeO-4-R1-C6H2)2}2] [R1 = Et, allyl, n-Pr, CHO, F, CH2(morpholino), the latter from the formyl derivative; R2 = Me, Et; not all combinations] are attained from Mannich reactions of commercial 2-methoxyphenols (27-74% overall yield, 2 steps). These crystalline (four X-ray structures) Ti(IV)-complexes are active against MCF-7, HCT-116, HT-29, PANC-1, and MDA-MB-468 cancer cell lines (GI50 = 0.5-38 µM). Their activity and cancer selectivity (vs nontumor MRC-5 cells) typically exceeds that of cisplatin (up to 16-fold). Proteomic analysis (in MCF-7) supported by other studies (G2/M cell cycle arrest, ROS generation, γH2AX production, caspase activation, annexin positivity, western blot, and kinase screens in MCF-7 and HCT-116) suggest apoptosis elicited by more than one mechanism of action. Comparison of these data to the modes of action proposed for salan Ti(IV) complexes is made.

A pilot study of the perceptions and acceptability of guidance using artificial intelligence in internet cognitive behaviour therapy for perfectionism in young people.

Perfectionism is a transdiagnostic process associated with a range of psychological disorders. Cognitive Behaviour Therapy for Perfectionism (CBT-P) has been demonstrated as efficacious across guided and unguided internet delivered interventions in reducing perfectionism and psychopathology. The aim of this pilot study was to understand perceptions and acceptability of an artificial intelligence supplemented CBT-P intervention (AI-CBT-P) in young people with lived experience of anxiety and depression (n = 8; age range 19-29 years, M = 24 years, SD = 3.77; 50 % female, 38 % male, 12 % non-binary). Young people reported that they were frequent users of artificial intelligence for study, work and general information, were positive about the intervention and using artificial intelligence for guidance in a self-help intervention, but also noted several concerns. Young people perceived numerous benefits to AI-CBT-P, including ease of access, low cost, lack of stigma and benefits for individuals with social anxiety. Overall, young people appear to be interested in, and have a positive view of, AI-CBT-P. Further research is now required to examine the feasibility and acceptability of the intervention.

A novel bluetongue virus serotype 2 strain isolated from a farmed Florida white-tailed deer (Odocoileus virginianus) arose from reassortment of gene segments derived from co-circulating serotypes in the Southeastern USA.

Bluetongue disease is a reportable animal disease that affects wild and farmed ruminants, including white-tailed deer (WTD). This report documents the clinical findings, ancillary diagnostics, and genomic characterization of a novel reassortant bluetongue virus serotype 2 (BTV-2) strain isolated from a dead Florida farmed WTD in 2022. Our analyses support that this BTV-2 strain likely stemmed from the acquisition of genome segments from co-circulating BTV strains in Florida and Louisiana. In addition, our analyses also indicate that genetically uncharacterized BTV strains may be circulating in the Southeastern USA; however, the identity and reassortant status of these BTV strains cannot be determined based on the VP2 and VP5 genome sequences. Hence, continued surveillance based on complete genome characterization is needed to understand the genetic diversity of BTV strains in this region and the potential threat they may pose to the health of deer and other ruminants.

The role of readiness and confidence to change in the treatment of atypical anorexia nervosa and bulimia nervosa.

OBJECTIVE: Atypical anorexia nervosa (AN) is a serious eating disorder that is more common in the population than AN. Despite this, people with atypical AN are less likely to be referred or admitted for eating disorder treatment and there is evidence that they are less likely to complete or benefit from existing interventions. This study examined whether baseline readiness and/or confidence moderated outcomes from 10-session cognitive behavioral therapy among people with atypical AN and bulimia nervosa (BN), and whether the impact of these variables differed between diagnoses. METHODS: Participants (n = 67; 33 with atypical AN) were a subset from an outpatient treatment study. Linear mixed model analyses were conducted to examine whether baseline readiness and/or confidence moderated outcomes. RESULTS: People with BN who had higher levels of readiness or confidence at baseline had steeper decreases in eating disorder psychopathology over time. There was no evidence that readiness or confidence moderated outcomes for people with atypical AN. DISCUSSION: This study suggests that the moderators that have been identified for other eating disorders may not apply for people with atypical AN and highlights a need for future work to routinely investigate whether theoretically or empirically driven variables moderate outcomes in this little-understood population. PUBLIC SIGNIFICANCE STATEMENT: People with bulimia nervosa with higher readiness and confidence experienced greater decreases in eating disorder symptoms than people with lower readiness and confidence when treated with cognitive behavioral therapy. These findings did not apply to people with atypical anorexia nervosa. Results demonstrate that future work is urgently required to identify helpful treatments for people with atypical anorexia nervosa as well as the variables that have a positive impact on outcomes in treatment for these individuals.

Factors Predicting Apparent Ophidiomycosis in Wild Brown Watersnakes (Nerodia taxispilota).

Ophidiomycosis, also known as snake fungal disease, is caused by Ophidiomyces ophidiicola and is a threat to snake conservation worldwide. Ophidiomycosis has been reported throughout much of the eastern US, and outbreaks have been associated with local population declines of already strained populations. Previous studies report significant variability in ophidiomycosis among species sampled, with higher prevalence typically observed in Nerodia spp. Although ophidiomycosis can lead to morbidity and mortality in affected individuals, little is known about disease dynamics in free-ranging populations. Herein, we examine how individual-specific factors (e.g., life stage [immature, mature], contaminant status, sex, hemograms) may be associated with ophidiomycosis status in the brown watersnake (Nerodia taxispilota). During 2018-19, we sampled 97 N. taxispilota from five locations along the Savannah River in South Carolina and Georgia, US. Ophidiomyces ophidiicola DNA was detected in 66 snakes for a prevalence of 68% (95% confidence interval, 59-77). Mature snakes had a significantly higher risk of apparent ophidiomycosis (skin lesions present and quantitative PCR [qPCR], positive) relative to immature snakes. Snakes classified as having possible (skin lesions present, but qPCR negative) or apparent ophidiomycosis exhibited a relative azurophilia and heterophilia compared with individuals classified as negative (P≤0.037). Nerodia taxispilota in this region appear to have a high prevalence of apparent ophidiomycosis (22%; 95% CI, 14-31), similar to previous reports from the southeastern US. Additional epidemiologic investigations are warranted to further elucidate other individual-specific and environmental factors that may dictate disease risk and outcomes in affected populations.
