Purpose: : This study aimed to identify the factors influencing physical restraint-related practice among nurses working in the intensive care unit (ICU). Methods: : The participants consisted of 169 ICU nurses in three general hospitals in B and U cities. Data were collected from December 2021 to January 2022 through a structured selfadministered questionnaire. Demographic characteristics, physical restraint-related practice, Person-centered Critical Care Nursing (PCCN), work environment, and attitudes toward physical restraint use were measured. For data analyses, hierarchical multiple regressions were conducted using SPSS/WIN 25.0. Results: : Clinical careers in the ICU, better work environments, higher PCCN levels, and more positive attitudes toward physical restraint use were associated with a better practice of physical restraints, which together explained 35.5% of the total variance of the outcome. Conclusion : Our findings suggest that to promote a safe physical restraintrelated practice among ICU nurses, it is important to improve the nursing environment, prepare guidelines for applying PCCN, and provide education for endorsing positive attitudes toward the use of physical restraints.

A 62-year-old woman without vascular risk factors presented with left-sided weakness and numbness. Magnetic resonance imaging (MRI) brain depicted acute right hemispheric infarcts in the cortical and subcortical white matter. Initial MR angiography (MRA) showed large thrombus at the right carotid bifurcation. Valvular atrial fibrillation (vAF) with severe tricuspid regurgitation (TR) was found on two-dimensional echocardiography. Serial follow-up computed tomography angiography (CTA) or MRA at 3, 9, and 15 days after anticoagulation alone showed complete resolution of the thrombus with no neurological deterioration. Our case suggests that prompt institution of anticoagulantion alone may result in radiologic resolution of the thrombus with improvement in patient’s clinical status.

The purpose of this study was to determine the characteristics of masticatory muscle activity and various oral condition factors, and to analyze their associations in order to improve the prevention and diagnosis of masticatory musclerelated diseases. This study included 30 Korean females (mean age of 20 years, age range of 19–21 years). Participants were instructed to complete a self-written questionnaire on factors that may affect their muscle activity. Surface electromyography was used to measure the activity of the masseter and temporalis muscles. We also observed the buccal mucosa ridge, tongue indentation, tooth cracks and fractures, and mandibular tori in the oral cavity. Spearman correlation analysis and the nonparametric Mann–Whitney U test were applied to the data. When subjects had temporomandibular disorder, the right temporalis muscle exhibited significantly lower activity (P<0.05). Those who had received orthodontic treatment within the previous 2 years showed significantly lower activity of the left masseter muscle (P<0.05). Those who had a left buccal mucosa ridge exhibited lower activity of the left masseter muscle and higher activity of the right temporalis muscle compared with those without such a ridge (P<0.05). Participants with no tongue indentation showed significantly higher activity in the left masseter muscle (P<0.05). These results indicate that there are relationships between masticatory muscle activity and various factors related to the oral condition.

Cadaver dissection is an effective method for learning structure and function of the human body. However, division of health science is conducting an anatomy lecture lean toward theory because it is impossible to operate their own practice program. This study was performed to propose a customized anatomy practice program plan that reflects needs of students majoring dental hygiene. A survey was conducted to 138 students majoring dental hygiene at D university. We used a structured questionnaire to analyze general characteristics of a subject, opinions about cadaver dissection, educational method and the demands of a program. Then we acquired frequency, mean, standard deviation, and correlation coefficient value. Furthermore, we also performed independent t-test and variance analysis (ANOVA) by using R program (version 3.2.2). A majority of students responded positively in items of necessity, satisfaction and comprehension of cadaver dissection. Dissection using cadaver marked a highest response (48.6%) among the methods of anatomic education. As for an appropriate time required for education, 72 students (52.2%) responded 30 minutes for an orientation time and 46 students (33.3%) for an observation time. Students also responded head and neck area and skeletal system to be the top priority for observation. In order to operate systemic cadaver dissection program, practical institutions should provide an active system. Contents of a necessity and procedure of cadaver donation should be included in preliminary education, with a thoughtful consideration to minimize negative psychological response of students during educational process. In observation, we should organize program focused on head and neck region and a three-dimensional structure of skeletal system. We expect our study to provide useful information in composing cadaver dissection program for dental hygiene students in the future.

OBJECTIVES: Although the coating of surface sealants to dental composite resin may potentially reduce bacterial adhesion, there seems to be little information regarding this issue. This preliminary in vitro study investigated the adhesion of Streptococcus mutans (S. mutans) on the dental composite resins coated with three commercial surface sealants. MATERIALS AND METHODS: Composite resin (Filtek Z250) discs (8 mm in diameter, 1 mm in thickness) were fabricated in a mold covered with a Mylar strip (control). In group PoGo, the surfaces were polished with PoGo. In groups PS, OG, and FP, the surfaces polished with PoGo were coated with the corresponding surface sealants (PermaSeal, PS; OptiGuard, OG; Fortify Plus, FP). The surfaces of the materials and S. mutans cells were characterized by various methods. S. mutans adhesion to the surfaces was quantitatively evaluated using flow cytometry (n = 9). RESULTS: Group OG achieved the lowest water contact angle among all groups tested (p < 0.001). The cell surface of S. mutans tested showed hydrophobic characteristics. Group PoGo exhibited the greatest bacterial adhesion among all groups tested (p < 0.001). The sealant-coated groups showed statistically similar (groups PS and FP, p > 0.05) or significantly lower (group OG, p < 0.001) bacterial adhesion when compared with the control group. CONCLUSIONS: The application of the surface sealants significantly reduced S. mutans adhesion to the composite resin polished with the PoGo.

Purpose: This study aimed to identify the effects of preparedness towards delegation, critical thinking disposition, and communicative competence on job satisfaction among comprehensive nursing care service ward nurses and general ward nurses. Methods: The participants in this study were 218 nurses from two university hospitals. Data were collected using self-administered questionnaires and were analyzed using SPSS Statistics/WIN 21.0, including descriptive statistics, x 2 test, Fisher's exact test, t-test, ANOVA, Scheffé test, Pearson’s correlation coefficient, and multiple linear regression analysis. Results: For comprehensive nursing care service ward nurses, the significant influencing factors on job satisfaction were age (β=-.37, p=.041), marital status (β=.35, p=.001), critical thinking disposition (β=.29, p=.003), and communicative competence (β=.28, p=.002) with the explanatory power was 39.0% (F=12.00, p<.001). On the other hand, for general ward nurses, the significant influencing factors on job satisfaction were advanced degree (β=.29, p=.047), critical thinking disposition (β=.23, p=.040), and communicative competence (β=.42, p<.001) with the explanatory power was 33.0% (F=11.78, p<.001). Conclusion The results of this study suggest the importance of developing and applying education programs to improve critical thinking disposition and communicative competence of nurses. This would enhance the comprehensive nursing service and increase overall nursing manpower resources. In addition, further studies are needed to improve nursing work environments and to develop strategies for enhancing preparedness towards delegation, which would increase the job satisfaction of nurses in the comprehensive nursing care service wards.

Corticotropin-releasing factor (CRF) is a peptide involved in the activation of the hypothalamic-pituitary-adrenal (HPA) axis. CRF is distributed not only along the HPA axis but also throughout pain-relevant anatomical sites. CRF elicits potent antinociception at the three main levels of pain transmissions: namely, the brain, spinal cord, and peripheral sensory neurons. The widespread distribution of CRF receptors 1 and 2 in the brain offers several targets wherein CRF could alter pain, some of which may be independent of the HPA axis. In this study, we assessed the expression of CRF and its receptors, CRF receptor type (CRFR)1 and CRFR2, in the spinal dorsal horn and dorsal root ganglion (DRG) in a rat model of neuropathic pain induced by spinal nerve injury (SNI). CRF was expressed in a few DRG neurons and primary afferent fibers in the dorsal horns of nasmall yi, Ukrainianve rats, and the CRF-positive neurons in DRG and fibers in the spinal dorsal horn were found to have increased after SNI. CRFR1 was not expressed in DRG or the dorsal horn and CRFR2 was expressed weakly in the small neurons in DRG in the nasmall yi, Ukrainianve rats. After SNI, CRFR1 was expressed in the activated microglia in the ipsilateral dorsal horn, and immunoreaction for CRFR2 was increased in the contralateral DRG following SNI. Consequently, it has been suggested that the increased expression of CRF and CRFR2 in DRG neurons and primary afferent fibers in dorsal horn, and CRFR1 in the activated microglia, may be involved in the mediation of stress responses as well as in microglial activation in the neuropathic pain state following SNI.

BACKGROUND: Microbial screening tests of umbilical cord blood (UCB) are essential for stem cell transplantation. We analyzed the microbial contamination rate and distribution of isolated microorganisms over 10 years of samples from the MEDIPOST Cord Blood Bank. In addition, we studied the influence of inoculum volume microorganism culture and compared the yield and speed of microorganism detection. METHODS: Microbial screening tests were performed using a manual method, which includes using an inoculum of 2 mL of plasma, a byproduct of UCB processing from pediatric culture bottles. When positive blood culture was detected, each set was once again inoculated with 2 mL and 4 mL of plasma. RESULTS: From 2004 to 2013, a total of 133,610 UCB units were screened, of which 1,311 (0.9%) tested positive for contamination. The most frequently identified microorganism was Escherichia coli (34.6%), followed by Bacillus spp. (12.8%), Enterococcus faecalis (5.3%) and Klebsiella pneumoniae (4.4%). The total yield rate increased by 0.2% over this time period, although the yield rate of Bacillus spp. increased by 8.3%. CONCLUSION: The results of this study could be used in many ways with both domestic and international data regarding cord blood contamination. Also, other microbiology laboratories using culture conditions similar to ours could refer this study when preparing guidelines. Finally, by detecting low levels of bacteria, we have contributed to cord blood safety.
