    Several self-report measures of conspiracist beliefs have been developed in Western populations, but examination of their psychometric properties outside Europe and North America is limited. This study aimed to examine the psychometric properties of three widely-used measures of conspiracist beliefs in Iran. We translated the Belief in Conspiracy Theory Inventory (BCTI), Conspiracy Mentality Questionnaire (CMQ), and Generic Conspiracist Belief Scale (GCBS) into Persian. Factorial validity was examined using principal-axis factor analysis in a community sample from Tehran, Iran (N = 544). Further, the relationships between scores on these measures and hypothesized antecedents (i.e., education, schizotypal personality, information processing style, superstitious beliefs, religiosity, and political orientation) were examined. Overall, we failed to find support for the parent factor structures of two of the three scales (BCTI and GCBS) and evidence of construct validity for all three scales was limited. These results highlight the necessity of further psychometric work on existing measures of conspiracy theories in diverse culturo-linguistic groups and the development of context-specific measures of conspiracist beliefs

    Olfactory ensheathing cells-based therapy for spinal cord injury (SCI) repair has been a possible treatment for clinical study because of their safety in autologous transplantation and potential regenerative capability. However, there are contradictory reports on the results after transplantation in animal models. The purpose of this research was to investigate the effect of acute transplantation of human mucosa-derived olfactory ensheathing cells (OECs) on the repair of the spinal cord. Human olfactory ensheathing cells were isolated from the human mucosa and cultured under supplemented neuronal cell culture medium. They were characterized by immunocytochemistry for olfactory ensheathing cell markers. We induced spinal cord injury at T8-T9 of rats by aneurysm clips and simultaneously injected two million OECs into subarachnoid space of spinal cord. Sensory and motor behaviors were recorded by tail-flick reflex (TFR) and BBB scores, respectively every week for seven weeks after injury. Morphology and S100-beta antigen expression in olfactory ensheathing cells of the human olfactory mucosa was confirmed by immunostaining. OECs transplantation did not recover inflammation, neuronal vacuolation, hemorrhage, and cyst formation. These findings suggest that OECs transplantation in this experimental setting did not lead to tissue regeneration to enhance locomotion. These results broaden current knowledge and are additions to the science and literature

    <p>Abstract</p> <p>Background</p> <p>Rapid and safe airway management has always been of paramount importance in successful management of critically ill and injured patients in the emergency department. The purpose of our study was to determine success rates of bag-mask ventilation and tracheal intubation performed by emergency medicine residents before and after completing their anesthesiology curriculum.</p> <p>Methods</p> <p>A prospective descriptive study was conducted at Nikoukari Hospital, a teaching hospital located in Tabriz, Iran. In a skills lab, a total number of 18 emergency medicine residents (post graduate year 1) were given traditional intubation and bag-mask ventilation instructions in a 36 hour course combined with mannequin practice. Later the residents were given the opportunity of receiving training on airway management in an operating room for a period of one month which was considered as an additional training program added to their Anesthesiology Curriculum. Residents were asked to ventilate and intubate 18 patients (Mallampati class I and ASA class I and II) in the operating room; both before and after completing this additional training program. Intubation achieved at first attempt within 20 seconds was considered successful. Successful bag-mask ventilation was defined as increase in ETCo<sub>2 </sub>to 20 mm Hg and back to baseline with a 3 L/min fresh gas-flow and the adjustable pressure limiting valve at 20 cm H<sub>2</sub>O. An attending anesthesiologist who was always present in the operating room during the induction of anesthesia confirmed the endotracheal intubation by direct laryngoscopy and capnography. Success rates were recorded and compared using McNemar, marginal homogeneity and paired t-Test tests in SPSS 15 software.</p> <p>Results</p> <p>Before the additional training program in the operating room, the participants had intubation and bag-mask ventilation success rates of 27.7% (CI 0.07-0.49) and 16.6% (CI 0-0.34) respectively. After the additional training program in the operating room the success rates increased to 83.3% (CI 0.66-1) and 88.8% (CI 0.73-1), respectively. The differences in success rates were statistically significant (P = 0.002 and P = 0.0004, respectively).</p> <p>Conclusions</p> <p>The success rate of emergency medicine residents in airway management improved significantly after completing anesthesiology rotation. Anesthesiology rotations should be considered as an essential component of emergency medicine training programs. A collateral curriculum of this nature should also focus on the acquisition of skills in airway management.</p

    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

    The COVID-19 pandemic has increased negative emotions and decreased positive emotions globally. Left unchecked, these emotional changes might have a wide array of adverse impacts. To reduce negative emotions and increase positive emotions, we tested the effectiveness of reappraisal, an emotion-regulation strategy that modifies how one thinks about a situation. Participants from 87 countries and regions (n = 21,644) were randomly assigned to one of two brief reappraisal interventions (reconstrual or repurposing) or one of two control conditions (active or passive). Results revealed that both reappraisal interventions (vesus both control conditions) consistently reduced negative emotions and increased positive emotions across different measures. Reconstrual and repurposing interventions had similar effects. Importantly, planned exploratory analyses indicated that reappraisal interventions did not reduce intentions to practice preventive health behaviours. The findings demonstrate the viability of creating scalable, low-cost interventions for use around the world

    Introduction: Unsuccessful tracheal intubation is considered the most common cause of anesthesia death or brain damage. This study delineates our experience recommending modifications in the cricothyroidotomy technique .Methods: Thirty emergency medicine residents of participated in a study performed on the human simulator moulage in Skill Laboratory of Tabriz University of Medical Science. The cricothyroid membrane was punctured using a 16-gauge cannula. Later, J guide wire was advanced into trachea and standard 16-gauge intravenous cannula with a removable needle stylet withdrawn after the puncture being dilated by a dilator. Consequently, a cuffed tracheal tube (ID= 6) was introduced from the foramen. Results: From 30 residents, 18 residents performed cricothyroidotomy within 1 minute, 7 residents in 2 minutes and 5 residents failed to fulfill the procedure. Conclusion: Several studies using cadavers and human simulators have demonstrated the pre-hospital feasibility of this technique. However, descriptions of clinical pre-hospital experience with percutaneous cricothyroidotomy are limited. This study shows that skill lab may help residents to acquire techniques required in management of difficult airway
