RESUMO

Experimental research has demonstrated that a stress-is-enhancing mindset can be induced and can improve outcomes by presenting information on the enhancing nature of stress. However, experimental evidence, media portrayals, and personal experience about the debilitating nature of stress may challenge this mindset. Thus, the traditional approach of focusing on the more "desired" mindset without arming participants against encounters with the less desired mindsets may not be sustainable in the face of conflicting information. How might this limitation be resolved? Here, we present three randomized-controlled interventions that test the efficacy of a "metacognitive approach." In this approach, participants are given more balanced information about the nature of stress along with metacognitive information on the power of their mindsets aimed at empowering them to choose a more adaptive mindset even in the face of conflicting information. In Experiment 1, employees of a large finance company randomized to the metacognitive mindset intervention reported greater increases in stress-is-enhancing mindsets and greater improvements in self-reported measures of physical health symptoms and interpersonal-skill work performance 4 weeks later compared to a waitlist control. Experiment 2, adapted to be distributed electronically via multimedia modules, replicates the effects on stress mindset and symptoms. Experiment 3 compares the metacognitive stress mindset intervention with a more traditional stress mindset manipulation. The metacognitive approach led to greater initial increases in a stress-is-enhancing mindset relative to the traditional intervention, and these increases were sustained after exposure to contradictory information. Taken together, these results provide support for a metacognitive approach to mindset change. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

RESUMO

BACKGROUND: Despite the benefits of physical activity for individuals with knee osteoarthritis (KOA), physical activity levels are low in this population. OBJECTIVES: We conducted a repeated cross-sectional study to compare mindset about physical activity among individuals with and without KOA and to investigate whether mindset relates to physical activity. METHODS: Participants with (n = 150) and without (n = 152) KOA completed an online survey at enrollment (T1). Participants with KOA repeated the survey 3 weeks later (T2; n = 62). The mindset questionnaire, scored from 1 to 4, assessed the extent to which individuals associate the process of exercising with less appeal-focused qualities (e.g., boring, painful, isolating, and depriving) versus appeal-focused (e.g., fun, pleasurable, social, and indulgent). Using linear regression, we examined the relationship between mindset and having KOA, and, in the subgroup of KOA participants, the relationship between mindset at T1 and self-reported physical activity at T2. We also compared mindset between people who use medication for management and those who use exercise. RESULTS: Within the KOA group, a more appeal-focused mindset was associated with higher future physical activity (ß=38.72, p = 0.006) when controlling for demographics, health, and KOA symptoms. Individuals who used exercise with or without pain medication or injections had a more appeal-focused mindset than those who used medication or injections without exercise (p<0.001). A less appeal-focused mindset regarding physical activity was not significantly associated with KOA (ß = -0.14, p = 0.067). Further, the mindset score demonstrated strong internal consistency (α = 0.92; T1; n = 150 and α = 0.92; T2; n = 62) and test-retest reliability (intraclass correlation coefficient (ICC) > 0.84, p < 0.001) within the KOA sample. CONCLUSIONS: In individuals with KOA, mindset is associated with future physical activity levels and relates to the individual's management strategy. Mindset is a reliable and malleable construct and may be a valuable target for increasing physical activity and improving adherence to rehabilitation strategies involving exercise among individuals with KOA.

RESUMO

OBJECTIVE: To describe the epidemiology of sledding-related injuries among children and adults treated in US emergency departments (EDs). DESIGN: The researchers performed a retrospective analysis using data from the National Electronic Injury Surveillance System (NEISS). SETTING: The NEISS collects data on consumer products-related and sports-related injuries treated in US EDs from approximately 100 hospitals that represent a probability sample of >5000 hospitals. PATIENTS: Children (≤19 years of age) and adults who were treated for sledding-related injuries in EDs from 2008 to 2017. INDEPENDENT VARIABLES: The researchers analyzed characteristics that included sex, body part injured, injury diagnosis, disposition from the ED, injury locale, injury mechanism, and sled type. MAIN OUTCOME MEASURES: All cases of sledding-related injuries were identified using NEISS product codes for sleds (1217), toboggans (1273), snow disks (1274), and snow tubes (1299). RESULTS: An estimated 220 488 patients [95% confidence interval (CI): 169 839-271 137] were treated in EDs for sledding-related injuries. Overall, the injury rate decreased significantly for both children and adults. Children accounted for 69.7% of the injury cases. Fractures were the most common injury diagnosis for children (23.9%) and adults (27.4%). Compared to adults, children were more likely to sustain a head injury [relative risk (RR): 1.91 (95% CI: 1.73-2.13)] and be diagnosed with a concussion or closed-head injury (CHI) [RR: 1.58 (95% CI: 1.35-1.84)]. Most patients were injured by a collision (63.2%). Snow tube and disk riders were more likely to sustain a concussion or CHI compared to sled and toboggan riders [RR: 1.53 (95% CI: 1.18-1.99)]. Injuries predominantly occurred when patients collided with objects in the environment (47.2%). CONCLUSIONS: Although sledding-related injuries decreased over the study period, more research and education to prevent these injuries is needed. The injury patterns and risk of injury type differed by age, with more head injuries sustained by children. Sledding should be performed in obstacle-free areas to reduce the risk of collision and while wearing helmets to mitigate head injuries.

RESUMO

Endogenous active plasminogen activator inhibitor 1 (PAI-1) was targeted in vivo with monoclonal antibodies (mAbs) that redirect its reaction with proteinases to the substrate branch. mAbs were used as an adjunct to prourokinase (single-chain [sc] urokinase [uPA]) intrapleural fibrinolytic therapy (IPFT) of tetracycline-induced pleural injury in rabbits. Outcomes of scuPA IPFT (0.25 or 0.0625 mg/kg) with 0.5 mg/kg of mouse IgG or mAbs (MA-33H1F7 and MA-8H9D4) were assessed at 24 hours. Pleural fluid (PF) was collected at 0, 10, 20, and 40 minutes and 24 hours after IPFT and analyzed for plasminogen activating (PA), uPA, fibrinolytic activities, levels of total plasmin/plasminogen, α-macroglobulin (αM), mAbs/IgG antigens, free active uPA, and αM/uPA complexes. Anti-PAI-1 mAbs, but not mouse IgG, delivered with an eightfold reduction in the minimal effective dose of scuPA (from 0.5 to 0.0625 mg/kg), improved the outcome of IPFT (P < 0.05). mAbs and IgG were detectable in PFs at 24 hours. Compared with identical doses of scuPA alone or with IgG, treatment with scuPA and anti-PAI-1 mAbs generated higher PF uPA amidolytic and PA activities, faster formation of αM/uPA complexes, and slower uPA inactivation. However, PAI-1 targeting did not significantly affect intrapleural fibrinolytic activity or levels of total plasmin/plasminogen and αM antigens. Targeting PAI-1 did not induce bleeding, and rendered otherwise ineffective doses of scuPA able to improve outcomes in tetracycline-induced pleural injury. PAI-1-neutralizing mAbs improved IPFT by increasing the durability of intrapleural PA activity. These results suggest a novel, well-tolerated IPFT strategy that is tractable for clinical development.

RESUMO

OBJECTIVE: Although there is a growing recognition of the importance of active communication behaviours from the incoming clinician receiving a patient handover, there are currently no agreed-upon measures to objectively describe those behaviours. This study sought to identify differences in incoming clinician communication behaviours across levels of clinical training for physicians and nurses. METHODS: Handover observations were conducted during shift changes for attending physicians, resident physicians, registered nurses and nurse practitioners in three medical intensive care units from July 2011 to August 2012. Measures were the number of interjections from the incoming clinician and the communication mode of those interjections. Each collaborative cross-check, a specific type of interactive question, was subsequently classified by level of assertiveness. RESULTS: 133 patient handovers were analysed. Statistical differences were found in both measures. Higher levels of training were associated with fewer interjections, and a higher proportion of interactive questioning to detect erroneous assessments and actions by the incoming provider. All groups were observed to use the least assertive level of a collaborative cross-check, which contributed to misunderstandings. Nurses used less assertive collaborative cross-checks than physicians. CONCLUSIONS: Differences across clinician type and levels of clinical training were found in both measures during patient handovers. The findings suggest that training could enable physicians and nurses to learn communication competencies during patient handovers which were used more frequently by more experienced practitioners, including interjecting less frequently and using interactive questioning strategies to clarify understanding, and assertively question the appropriateness of diagnoses, treatment plans and prognoses. Accompanying cultural change initiatives might be required to routinely employ these strategies in the clinical setting, particularly for nursing personnel.

RESUMO

Previous research has examined parafoveal processing during silent reading, but little is known about the role of these processes in oral reading. Given that masking parafoveal information slows down silent reading, we asked whether a similar effect also occurs in oral reading. To investigate the role of parafoveal processing in silent and oral reading, we manipulated the parafoveal information available to readers by changing the size of a gaze-contingent moving window. Participants read silently and orally in a one-word window and a three-word window condition as we monitored their eye movements. The lack of parafoveal information slowed reading speed in both oral and silent reading. However, the effects of parafoveal information were larger in silent reading than in oral reading, because of different effects of preview information on both when the eyes move and how often. Parafoveal information benefitted silent reading for faster readers more than for slower readers.

RESUMO

Cultural differences have been observed in scene perception and memory: Chinese participants purportedly attend to the background information more than did American participants. We investigated the influence of culture by recording eye movements during scene perception and while participants made recognition memory judgements. Real-world pictures with a focal object on a background were shown to both American and Chinese participants while their eye movements were recorded. Later, memory for the focal object in each scene was tested, and the relationship between the focal object (studied, new) and the background context (studied, new) was manipulated. Receiver-operating characteristic (ROC) curves show that both sensitivity and response bias were changed when objects were tested in new contexts. However, neither the decrease in accuracy nor the response bias shift differed with culture. The eye movement patterns were also similar across cultural groups. Both groups made longer and more fixations on the focal objects than on the contexts. The similarity of eye movement patterns and recognition memory behaviour suggests that both Americans and Chinese use the same strategies in scene perception and memory.
