62/100,000 doses. The most frequently reported AEFI was fever/redness/induration (48.82/100,000 doses).Conclusion Our findings illustrated the high level of vaccine safety since the majority of those reported were not serious, or coincidentally associated with vaccination. Furthermore, the national AEFI surveillance system should be continuously used as a surveillance tool for monitoring of AEFI.Rationale Delirium is common in critically ill patients and associated with deleterious outcomes. Non-pharmacologic interventions are recommended in current delirium guidelines, but their effects have not been unequivocally established. Objective To determine the effects of a multicomponent nursing intervention program on delirium in the Intensive Care Unit. Methods Stepped wedge cluster randomized controlled trial, conducted in Intensive care units of 10 centers. Adult critically ill surgical, medical or trauma patients at high risk to develop delirium were included. A multicomponent nursing intervention program focusing on modifiable risk factors was implemented as standard of care. Primary outcome was the number of delirium-free and coma-free days alive in 28 days after Intensive Care Unit admission. Measurements and main results A total of 1749 patients were included. Time spent per 8 hours shift on interventions was median [IQR] 38 [14-116] in the intervention period and median 32 [13-73] minutes in the control period (p=0.44). Patients in the intervention period had median 23 [4-27] delirium-free and coma-free days alive, compared to median 23 [5-27] days for patients in the control group (mean difference -1.21 days, 95%CI -2.84 to 0.42 days; p=0.15). Also, the number of delirium days was similar median 2 [1-4] days (ratio of medians 0.90, 95%CI 0.75 to 1.09; p=0.27). Conclusion In this large randomized controlled trial in adult ICU patients, a limited increase was achieved of the use of nursing interventions, and no change in the number of delirium-free and coma-free days alive in 28 days could be determined.

The International Organization for Standardization Technical Committee 94, Subcommittee 15 utilized work of breathing to evaluate airflow resistance for all classes of respiratory protective devices as part of their development of performance standards regarding respiratory protective devices. The objectives of this study were (1) to evaluate the relationship between the International Organization for Standardization's work of breathing measurements and the National Institute for Occupational Safety and Health's breathing resistance test results; (2) to provide scientific bases for standard development organizations to decide if work of breathing should be adopted; and (3) to establish regression equations for manufacturers and test laboratories to estimate work of breathing measurements using breathing resistance data. A totSafety and Health's breathing resistance were found to be strongly and positively correlated (r values of 0.7-0.9) at each work rate for inhalation and exhalation. In addition, linear and multiple regression models (R-squared values of 0.5-0.8) were also established to estimate work of breathing using breathing resistance. Work of breathing was correlated higher to breathing resistance for full-facepiece and half-mask elastomeric respirators than filtering facepiece respirators for inhalation. For exhalation, filtering facepiece respirators were correlated much better than full-facepiece and half-mask elastomeric respirators. Therefore, the National Institute for Occupational Safety and Health's breathing resistance may reasonably be used to predict work of breathing for air-purifying respirators. The results could also be used by manufacturers for product development and evaluation.
The recommended methodof cardiopulmonary resuscitation (CPR) has been closed-chest cardiac compressions, but the development of CPR adjunctive devices has called into question the efficacy and role of these adjunctive devices. In this review, we provide a comprehensive evaluation and discussion on the commercially available noninvasive CPR adjuncts used during out-of-hospital cardiac arrest (OHCA).

We review the three most common CPR adjunctive devices the piston mechanism, the load distributing band, and the impedance threshold device. All three CPR adjunctive devices have preclinical data to support their use during cardiac arrest. In clinical trials, limited data show improvement in survival and neurologic recovery for these devices, and there is insufficient high-level evidence to support their use over manual chest compressions. However, there is a role for them when adequate manual chest compressions are not feasible.

The commercially available CPR adjuncts do not consistently show improved outcomes in the literature. There is still a need for research and development into innovative solutions to improve OHCA survival and neurologic recovery. Efforts focused on increasing the speed of CPR initiation and increasing perfusion to the cerebral and coronary vasculature have the potential to advance resuscitative practices.

While it is clear that cystic fibrosis airway disease begins at a very young age, the early and subsequent steps in disease pathogenesis and the relative contribution of infection, mucus, and inflammation are not well understood.

As one approach to assessing the early contribution of infection, we tested the hypothesis that early and continuous antibiotics would decrease the airway bacterial burden. We thought that, if it does, it might reveal aspects of the disease that are more or less sensitive to decreasing infection.

Three groups of pigs were studied from birth until ~3 weeks of age 1) wild-type, 2) cystic fibrosis, and 3) cystic fibrosis pigs treated continuously with broad-spectrum antibiotics from birth until study completion. Disease was assessed with chest computed tomography, histopathology, microbiology, and bronchoalveolar lavage.

Disease was present by 3 weeks of age in cystic fibrosis pigs. Continuous antibiotics from birth improved chest computed tomography imaging abnormalities and airway mucus accumulation, but not airway inflammation in the cystic fibrosis pig model. However, reducing bacterial infection did not improve two disease features already present at birth in cystic fibrosis pigs, air trapping and submucosal gland duct plugging. In the cystic fibrosis sinuses, antibiotics did not prevent the development of infection, disease, or the number of bacteria but did alter the bacterial species.

These findings suggest that cystic fibrosis airway disease begins immediately following birth, and that early and continuous antibiotics impact some, but not all, aspects of CF lung disease development.

Basketball is a contact sport with complex movements that include jumps, turns, and changes in direction, which cause frequent musculoskeletal injuries in all regions of the body. Also, injury patterns among athletes, particularly basketball players, continue to evolve and change. The current retrospective epidemiologic study aimed to investigate the incidence, severity, and sports-related risk factors of injuries in Iranian basketball players from 2019 to 2020.

Using the Information Retrospective Injury Questionnaire (online version), data on basketball-related injuries were collected retrospectively for 204 basketball players of the Iranian league (professional super league and first-division league) during the 2019/2020 season.

A total of 628 injuries were reported, which was equivalent to 6.07 injuries/1000h. The ankle was the location of most injuries (n=116 or 26.9%; overuse injuries (n=40 or 20.3%)), followed by lower back/pelvis injuries (acute injury n =67 (15.5%) and overuse injuries (n=23; 11nt than during competition with different patterns of injuries.The coronavirus disease 2019 (COVID-19) pandemic has disproportionately impacted older individuals, those with lower educational attainment, and Black and Hispanic populations, yet vaccine hesitancy remains prevalent. Because widespread uptake of COVID-19 vaccines is critical to end the pandemic, addressing vaccine hesitancy is an important public health priority. Between April 1, 2020 and March 16, 2021, we have repeatedly surveyed a nationally representative online panel of adults and have tracked their stated likelihood of getting COVID-19 vaccinations. We present new evidence that in recent months disparities in self-reported likelihood of COVID-19 vaccination have narrowed by race/ethnicity, with an increasing proportion of Black individuals and Hispanic individuals indicating that they are likely to get a vaccine. At the same time, younger adults have progressively become less likely than older adults to state they will get a COVID-19 vaccine. Most vaccine-hesitant individuals are concerned about both vaccine efficacy and safety and do not trust the vaccine development or vaccine approval process. We conclude that outreach efforts to minority populations may be achieving their objectives in raising confidence in COVID-19 vaccines, but special outreach efforts are needed to address both vaccine hesitancy among younger adults and mistrust in the vaccine development and approval process.Objective The Theory of Planned Behavior (TPB) is one of the most robust models in explaining health-related behavior. In this study, we tested the extended TPB to predict university students' intentions to uptake COVID-19 vaccination.Methods An online cross-sectional survey was developed to investigate students' intention to uptake the COVID-19 vaccine based on the components of the TPB (i.e., attitude, subjective norms, and perceived behavioral control) and extended components (i.e., knowledge about COVID-19, risk perception of COVID-19, and past influenza vaccination behavior). Non-probability sampling was used to collect data from 3145 students from 43 universities in mainland China in January 2021. Structural equation modeling (SEM) was applied to examine the proposed model. Acalabrutinib Enrolled students were relatively young (mean age = 20.80 years; SD = 2.09), half of them are female (50.2%), and most of them were studying in undergraduate programs (n = 3026; 96.2%).Results The results showed that students' knowledge of the COVID-19 vaccine and risk perception of COVID-19 positively influenced their attitude toward the uptake of a COVID-19 vaccine. Also, students' attitude toward COVID-19 vaccination uptake and their past influenza vaccination uptake behaviors were positively associated with the intention to uptake COVID-19 vaccination. Subjective norm and perceived behavioral control were not significant predictors for the intention to uptake COVID-19 vaccination (R2 = 0.49).Conclusions The present study demonstrated that the extended TPB appears to be an efficient model with the focus on attitude, knowledge, risk perception, and past influenza vaccination uptake behaviors in explaining students' intention for COVID-19 vaccination.
