Introduction:High-quality chest compressions (CCs) are associated with high survival rates and good neurological outcomes in cardiac arrest patients. The 2015 American Heart Association (AHA; Dallas, Texas USA) Guidelines for Resuscitation defined and recommended high-quality CCs during cardiopulmonary resuscitation (CPR). However, CPR providers struggle to achieve high-quality CCs. There is a debate about the use of backboards during CPR in literature. Some studies suggest backboards improve CC quality, whereas others suggest that backboards can cause delays. This is the first study to evaluate all three components of high-quality CCs: compression depth, recoil depth, and rate, at the same time with a high number of subjects. This study evaluated the impact of backboards on CC quality during CPR. The primary outcome was the difference in successful CC rates between two groups.Methods:This was a randomized, controlled, single-blinded study using a high-fidelity mannequin. The successful CC rates, means CC depths, recoil depths, and rates achieved by 6th-grade undergraduate medical students during two minutes of CPR were compared between two randomized groups: an experimental group (backboard present) and a control group (no backboard).Results:Fifty-one of all 101 subjects (50.5%) were female, and the mean age was 23.9 (SD = 1.01) years. The number and the proportion of successful CCs were significantly higher in the experimental group (34; 66.7%) when compared to the control group (19; 38.0%; P = .0041). The difference in mean values of CC depth, recoil depth, and CC rate was significantly higher in the experiment group.Conclusion:The results suggest that using a backboard during CPR improves the quality of CCs in accordance with the 2015 AHA Guidelines.Sanri E, Karacabey S.

ABSTRACT Objective To evaluate the difference in orthodontic root resorption between root-filled and vital teeth. Material and Methods Sixteen individuals who required bilateral premolar tooth extraction due to orthodontic treatment and had a previously root-filled premolar tooth on one side were included in the study. The experimental group consisted of root-filled premolar teeth, and the control group consisted of contralateral vital premolar teeth. A 150-g buccally directed force was applied to these teeth using 0.017 × 0.025-inch TMA cantilever springs. The premolars were extracted 8 weeks after the application of force. Images were obtained using micro–computed tomography. Resorption measurements were obtained using the Image J program. Results The mean values for resorption were 0.08869 mm3 for the root-filled teeth and 0.14077 mm3 for the contralateral teeth, indicating significantly less resorption for the root-filled teeth compared with the contralateral teeth after the application of orthodontic force (P = .003). In both groups, the most resorption was seen on the cervical-buccal and apical-lingual surfaces. The mean resorption value of the cervical region was 0.06305 mm3 in the control group and 0.0291 mm3 in the experimental group, and the difference was statistically significant (P = .002). Conclusions Root-filled teeth showed significantly less orthodontic root resorption than vital teeth.

Background. The incidence of thyroid nodules increases in the general population. Similarly, we have also seen a dramatic increase in the number of thyroid surgeries. However, the mortality rate of thyroid cancer remained stable or even decreased. The purpose of our study was to investigate whether thyroid cancer affects the malignant risk of the contralateral TI-RADS 3 and 4 nodules. Methods. We conducted a retrospective cohort study in our institution for all thyroid procedures due to nodules from December 2018 to December 2019. All eligible patients were divided into the experimental group (bilateral nodules) and the control group (unilateral nodules) to assess whether the proportion of malignant nodules was different between the two groups. Multivariate logistic regression analysis was used to control potential confounding factors to investigate whether their differences were statistically significant. Results. A total of 330 patients underwent thyroid surgery, of whom 137 were eligible, including 84 in the experimental group and 53 in the control group. The proportion of malignant nodules was significantly different between the experimental group and the control group (29.8% versus 58.5%, unadjusted OR 0.30, 95% CI: 0.17–0.82, p = 0.001 ). However, after controlling for potential confounding factors, including age ( p = 0.004 ), gender ( p = 0.775 ), and TI-RADS classification ( p ≤ 0.001 ), we found that the difference was not significant (adjusted OR 1.08, 95% CI: 0.39–3.01, p = 0.886 ). Conclusion. There is no evidence that thyroid cancer affects the malignant risk of the contralateral TI-RADS 3 and 4 nodules. This study has been registered with the Chinese Clinical Trial Registry (clinical trial registration number: ChiCTR2000038611, registration time: September 26, 2020).

Abstract The present study attempted to investigate the impact of concept mapping strategy which is based on the theory of meaningful learning on retention of collocations. Moreover, the difference between the male and female learners exposed to the experimental condition was also examined. For this purpose, 90 EFL learners studying general English course at Urmia University were selected out of 115 learners according to their level of proficiency (PET test). Participants were assigned into two classes (class 1 (control group) = 48, class 2 (experimental group) = 42). Both groups received pre-test and post-test; however, they did get different instructions. Concept-mapping teaching strategy was used with experimental group participants while conventional instruction was employed in the control group. The results of this study support the fact that the use of concept mapping as a component of the instructional lesson can be an efficient model for fostering the collocation learning performance of learners with intermediate level of proficiency. However, there was not any statistically significant effect for gender.
