Achieving conservation outcomes requires concerted engagement from many people across diverse societies. However, many conservation practitioners struggle to engage new audiences. Research suggests one effective strategy to reach nonengaged individuals is to encourage interested conservation actors to share information, provide resources and assistance, and organize local events to recruit others; we call these "diffusion behaviors." Previous studies suggest few conservation actors who engage in personal-sphere PEB also engage in diffusion PEB, potentially because these behaviors have unique barriers which have yet to be identified. We investigated if there are different psychosocial drivers of diffusion and personal-sphere PEB by surveying residents in Colorado, USA about their personal-sphere wildscape behaviors (e.g. Bovine Serum Albumin compound library chemical planting native plants) and diffusion wildscape behaviors (e.g. helping a friend plant native plants). Including diffusion-specific psychosocial variables led to better predictions of both personal-sphere and diffusion PEB. Diffusion-specific self-efficacy, social and environmental response efficacy, and reputational concerns about perceived competence were significant predictors of diffusion behavior. Diffusion-specific environmental response efficacy and injunctive norms enforced through sanctioning significantly predicted personal-sphere behavior. Personal-sphere self-efficacy and dynamic norm beliefs predicted both behavior types. Our findings suggest that research should consider personal-sphere and diffusion PEB as distinct domains and should investigate the power of diffusion-specific perceptions. Conservation outreach programs seeking to encourage diffusion of PEB may benefit from designing programming to try to change these perceptions.Although health anxiety and corresponding safety behaviors can facilitate disease transmission avoidance, they can be maladaptive in excess, including during the coronavirus pandemic. Disgust proneness (i.e., tendency to experience and be sensitive to disgust) is one factor that may predict elevated coronavirus anxiety and safety behaviors during the pandemic, given the role of disgust in avoiding disease transmission. The present study examined the relations between pre-pandemic disgust proneness and coronavirus anxiety and safety behaviors in community adults who completed a 2016 study and were re-contacted on 4/1/2020 (N = 360). Interactions between pre-pandemic disgust proneness and current perceived stress were tested to examine a diathesis-stress model of the role of disgust proneness in anxiety response to the pandemic. Increased pre-pandemic disgust proneness predicted increased coronavirus anxiety and safety behaviors, controlling for number of COVID-19 cases by state. Consistent with a diathesis-stress model, current perceived stress moderated this effect, such that highest coronavirus anxiety and safety behaviors were reported by those with high disgust proneness and high stress. Trait disgust proneness may be a vulnerability factor for anxiety responses to the coronavirus pandemic, particularly among individuals experiencing high stress. Assessing disgust proneness and current stress may facilitate targeted anxiety intervention during the pandemic.

Aerobic exercise (AE) demonstrated an overall medium treatment effect in anxiety disorders (AD) but there is evidence for an "intensity-response" relationship. High intensity interval training (HIIT) was highly effective on a range of (mental) health parameters. However, so far no randomised-controlled trial (RCT) investigated the efficacy of HIIT in AD.

33 patients with generalized anxiety disorder (GAD) were randomly assigned to 12-day HIIT or a training of lower intensity (LIT). Anxiety, comorbid depression, stress-related bodily symptoms and perceived control over anxiety related stimuli (PC) were assessed at baseline, post-training and 30 days after baseline by using the Penn State Worry Questionnaire (PSWQ), the Hamilton Inventories for Anxiety and Depression (Ham-A, Ham-D), the Screening for Somatoform Symptoms-7 (SOMS-7) and the Anxiety Control Questionnaire (ACQ-R).

Both interventions showed moderate or large effects on all clinical measures. However, effects for HIIT were generally about twice as high as for LIT. PC negatively correlated with GAD severity in the whole sample at baseline but an association of training-induced changes in PC and worrying were exclusively detectable in HIIT.

HIIT was highly effective and fast acting in GAD. Therefore, it may complement first-line treatment approaches in this condition.

Evaluate the acute effects of non-invasive positive pressure ventilation (NiPPV) during high-intensity exercise on endothelial function in patients with coexisting chronic obstructive pulmonary disease (COPD) and heart failure (HF).

This is a randomized, double blinded, sham-controlled study involving 14 COPD-HF patients, who underwent a lung function test and Doppler echocardiography. On two different days, patients performed incremental cardiopulmonary exercise testing (CPET) and two constant-work rate tests (80% of CPET peak) receiving Sham or NiPPV (bilevel mode - Astral 150) in a random order until the limit of tolerance (Tlim). Endothelial function was evaluated by flow mediated vasodilation (FMD) at three time points 1) Baseline; 2) immediately post-exercise with NiPPV; and 3) immediately post-exercise with Sham.

Our patients had a mean age of 70±7 years, FEV

1.9±0.7L and LVEF 41±9%. NIPPV resulted in an increased Tlim (NiPPV 130±29s vs Sham 98±29s p=0.015) and SpO

(NiPPV 94.7±3.5% vs Sham 92.7±5.2% p=0.03). Also, NiPPV was able to produce a significant increase in FMD (%) (NiPPV 9.2±3.1 vs Sham 3.6±0.7, p<0.05), FMD (mm) (NiPPV 0.41±0.18 vs Sham 0.20±0.11, p<0.05), Blood flow velocity (NiPPV 33±18 vs Baseline 20±14, p<0.05) and Shear Stress (SS) (NiPPV 72±38 vs Baseline 43±25, p<0.05). We found correlation between Tlim vs. ΔSS (p=0.03; r=0.57). Univariate-regression analysis revealed that increased SS influenced 32% of Tlim during exercise with NiPPV.

NiPPV applied during high-intensity exercise can acutely modulate endothelial function and improve exercise tolerance in COPD-HF patients. In addition, the increase of SS positively influences exercise tolerance.
