The psychological science accelerator’s COVID-19 rapid-response dataset

In response to the COVID-19 pandemic, the Psychological Science Accelerator coordinated three large-scale psychological studies to examine the effects of loss-gain framing, cognitive reappraisals, and autonomy framing manipulations on behavioral intentions and affective measures. The data collected (April to October 2020) included specific measures for each experimental study, a general questionnaire examining health prevention behaviors and COVID-19 experience, geographical and cultural context characterization, and demographic information for each participant. Each participant started the study with the same general questions and then was randomized to complete either one longer experiment or two shorter experiments. Data were provided by 73,223 participants with varying completion rates. Participants completed the survey from 111 geopolitical regions in 44 unique languages/dialects. The anonymized dataset described here is provided in both raw and processed formats to facilitate re-use and further analyses. The dataset offers secondary analytic opportunities to explore coping, framing, and self-determination across a diverse, global sample obtained at the onset of the COVID-19 pandemic, which can be merged with other time-sampled or geographic data

A global experiment on motivating social distancing during the COVID-19 pandemic

Finding communication strategies that effectively motivate social distancing continues to be a global public health priority during the COVID-19 pandemic. This cross-country, preregistered experiment (n = 25,718 from 89 countries) tested hypotheses concerning generalizable positive and negative outcomes of social distancing messages that promoted personal agency and reflective choices (i.e., an autonomy-supportive message) or were restrictive and shaming (i.e., a controlling message) compared with no message at all. Results partially supported experimental hypotheses in that the controlling message increased controlled motivation (a poorly internalized form of motivation relying on shame, guilt, and fear of social consequences) relative to no message. On the other hand, the autonomy-supportive message lowered feelings of defiance compared with the controlling message, but the controlling message did not differ from receiving no message at all. Unexpectedly, messages did not influence autonomous motivation (a highly internalized form of motivation relying on one’s core values) or behavioral intentions. Results supported hypothesized associations between people’s existing autonomous and controlled motivations and self-reported behavioral intentions to engage in social distancing. Controlled motivation was associated with more defiance and less long-term behavioral intention to engage in social distancing, whereas autonomous motivation was associated with less defiance and more short- and long-term intentions to social distance. Overall, this work highlights the potential harm of using shaming and pressuring language in public health communication, with implications for the current and future global health challenges

Endovascular Repair of Thoracoabdominal Aortic Aneurysm in High-Surgical Risk Patients: Fenestrated and Branched Endografts

Background: To report early and mid-term results of endovascular repair of thoracoabdominal aortic aneurysms (TAAAs) by using Cook Zenith fenestrated/branched endografts (FB-EVAR) in high surgical risk patients unfit for open repair (OR). Methods: Between January 2012 and April 2015, all the patients with TAAA, considered at high surgical risk for OR and treated by Cook Zenith FB-EVAR, were prospectively enrolled. Patients were studied using a thoracoabdominal computer tomography angiography (CTA) and dedicated software for advanced vessels analysis. Follow-up was performed by duplex ultrasound (DU), contrast-enhanced DU, and/or CTA. Early end points were the following: technical success (TS), spinal cord ischemia (SCI), and 30-day morbidity/mortality. Follow-up end points were the following: survival, TAAA-related mortality, target visceral vessels (TVV) patency, type I/III endoleaks, and freedom from reinterventions (FFRs). Results: Thirty patients (male 77%, mean age 73 ± 7 years, American Society of Anesthesiologists 3/4 60%/40%) affected by TAAA type I (4%), II (21%), III (57%), and IV (18%) were enrolled. The mean aneurysm diameter was 66 ± 14 mm. The overall number of TVV was 107 (3.5 ± 0.9 vessels/patients). Custom-made and off-the-shelf endografts were used in 22 (73%) and 8 (23%) cases, respectively. The procedure was performed in multiple steps in 23 cases (77%). There were not intraoperative mortality and type I-III endoleaks, and the TVV patency was 97% (104/107). TS was 87%.There were 2 irreversible paraplegias (6.6%) and 1 reversible paraparesis (3.4%). Postoperative cardiac and pulmonary complications occurred in 2 (6.6%) and 2 (6.6%) patients, respectively. Renal function worsening (≥30% of the baseline level) was detected in 4 cases (13%). The 30-day mortality was 6.6%. Survival at 6, 12, and 24 months was 90%, 85%, and 68%, respectively. There was no TAAA-related mortality. The TVV patency at 3, 6, and 24 months was 95%, 90%, and 90%, respectively, and there were no type I-III endoleaks. FFRs at 6, 12, and 24 months was 88%. Conclusion: The endovascular repair of TAAA by using Cook Zenith fenestrated/branched endografts is feasible with acceptable technical and clinical results at early to mid-term results in patients at high surgical risk unfit for OR

Endovascular Treatment of Inflammatory Infrarenal Aortic Aneurysms

Objectives: The aim of this study was to evaluate short- and midterm outcomes of endovascular aneurysm repair in patients with inflammatory abdominal aortic aneurysm (IAAA) focusing on changes in perianeurysmal inflammation and hydronephrosis. Methods: A retrospective study was performed considering data prospectively gathered from 1998 to 2013 in 3 centers. Patient demographics, preoperative clinical characteristics, clinical presentation, preoperative imaging measurements, procedural, and postoperative data were collected. Main outcome was to define evolution of periaortic fibrosis and hydronephrosis at computed tomography angiography (CTA) during follow-up. Results: A total of 22 patients (male n = 20; mean age 70.9 years \ub1 9.3) were included (mean AAA diameter: 58 mm \ub1 11, symptomatic: 50%, ruptured: 9.1%). Hydroureteronephrosis was preoperatively diagnosed by CTA in 6 (27.3%) cases. Median clinical follow-up was 2.2 years (range 0.1-14.5). Nine patients died during follow-up. At 1, 2, 4, and 6 years, overall survival was 85.4%, 74.3%, 56.6%, and 49.5%, respectively. Among these 13 patients with CTA follow-up, the mean AAA diameter was 56.2 mm \ub1 15.5, and progression of sac diameter was detected in 1 (7.7%) patient. Median maximum thickness of perianeurysmal inflammation was 5 mm (range 2-11) and decreased/remained unchanged in 92.3% of patients. Regression of hydroureteronephrosis occurred in 3 of 5 patients available for follow-up. There were no cases of de novo hydroureteronephrosis. Conclusion: Endovascular treatment of IAAA has comparable short-term outcomes with non-IAAA. During midterm follow-up, aneurysm sac progression is rare, and perianeurysmal fibrosis decreases or remains unchanged in most cases. Hydronephrosis regression can occur in some but not all instances and thus warrants close surveillance

Planning and Endograft Related Variables Predisposing to Late Distal Type I Endoleaks

Objective: Late distal type I endoleak (ELIB) hampers the outcome of endovascular repair (EVAR) for abdominal aortic aneurysm (AAA); however, only few dedicated experiences have been reported in the literature. The aim of the study was to evaluate the incidence, presentation and treatment of late ELIB and to identify possible anatomical and technical predictors. Methods: All patients undergoing elective EVAR between 2008 and 2013 were collected prospectively. Follow up was by post-operative computed tomography angiography (CTA) performed within 30 days and CTA and/or duplex ultrasound (DUS) at six or 12 months and yearly thereafter. Patients with late ELIB, defined as distal type I endoleak detected more than six months after the primary intervention without endoleak on the intraoperative completion angiogram and on the post-operative CTA, were retrospectively selected (G1) and compared with a control group with no ELIB (G2) homogeneous for clinical conditions, endograft implanted, and timing of follow up. The minimum follow up required for inclusion in the study was 24 months. Preoperative morphological aorto-iliac features and EVAR implant details were evaluated, and measurements performed after centre lumen line reconstructions using dedicated software. The differences between G1 and G2 were analysed using the chi-square test, the Student t test, and logistic regression. Results: Six hundred and sixteen patients were submitted to EVAR. ELIB was detected in 14 cases (2.3%) (G1) at a median follow up of 32.8 (IQR 48) months. In three of the 14 cases ELIB was symptomatic (AAA rupture, 2; pain, 1); in the remaining 11 cases it was asymptomatic and found incidentally at routine follow up. Treatment was by open repair in one case and by endovascular iliac leg extension in 13 cases. Hypogastric exclusion was necessary in two of 14 cases. Thirty patients were included in G2, with a median follow up of 41.2 (25) months. Common iliac artery length <4 cm (OR 5.3, 95% CI 1.1-29.5, p = .05), diameter > 15 mm (OR 3.5, 95% CI 1.2-10.9, p = .03), and severe thrombotic apposition (>50% of circumference) (OR 5, 95% CI 1.2-19.2, p = .02), at the iliac sealing zone were significant predictors of ELIB, on univariable analysis; oversizing of the iliac leg diameter < 10% and distal sealing > 1 cm above the hypogastric origin were independently associated with ELIB (OR 5.4, 95% CI 1.3-21.5, p = .01 and OR 6.6, 95% CI 1.1-39.3, p = .03, respectively), on multivariable analysis. Conclusion: The present data underline that ELIB is a non-negligible occurrence during long term EVAR follow up and requires further interventions, most often by endovascular solutions. According to the ELIB risk factors identified in this study, an iliac leg diameter oversize >10% and extensive common iliac artery coverage (<1 cm above the hypogastric origin) would be suggested to prevent this complication
