The Influence of Infection-related Characteristics and Patient Safety Culture on Awareness of Blood-borne Infection Prevention in Operating Room Nurses and General Ward Nurses

Purpose@#This study aimed to identify the factors influencing infection-related characteristics and patient safety culture on awareness of blood-borne infection prevention between operating room nurses and general ward nurses. @*Methods@#Participants were 198 nurses(operating room nurses 98 and general ward nurses: 100) working at three general hospitals and three university hospitals in three cities. Data were collected using a structured questionnaire from September 11 to October 14, 2020. Data were analyzed using descriptive statistics, t-tests, ANOVA, Pearson’s correlation coefficient, and multiple regression with IBM SPSS/WIN 26.0 program. @*Results@#Typically, 39.8% of nurses in the operating room and 24.0% of ward nurses experienced injuries such as needles and sharp instruments used by the patient. The awareness of patient safety culture was identified to be higher for the ward nurses. Factors influencing the awareness of blood-borne infection prevention in operating room nurses were patient safety culture and wearing protective equipment for infection prevention while nursing infected patients. Moreover, the explanatory power of these variables was 19.4%. In general ward nurses, the patient safety culture was identified as a significant predictor, which accounted for 16.5% of awareness of blood-borne infection prevention. @*Conclusion@#To prevent hospital infection, a strategy is needed to improve the level of awareness of blood-borne infection prevention and patient safety culture of operating room nurses. To this end, the difference in infection-related characteristics and influencing factors between the operating room nurses and the general ward nurses should be considered and planned.

The influence of learning presence and self-directed learning competency of nursing students on learning satisfaction in major subjects for online distance learning / 한국간호교육학회지

Purpose@#This study aimed to identify the influence of learning presence and self-directed learning ability on nursing students’ learning satisfaction according to the online learning method. @*Methods@#The participants of this study were 167 nursing students attending three universities in different cities. The data were collected from July 16 to July 23, 2021, via an online self-reported questionnaire. Using SPSS WIN 27.0, data were analyzed by descriptive statistics, Pearson’s correlation coefficient and a multiple regression analysis. @*Results@#The most effective online learning method experienced by nursing students was asynchronous online learning according to 58.2% of the respondents, while 30.3% of the respondents answered synchronous online learning. The main merit of asynchronous online learning was that it was possible to listen repeatedly (61.7%) to lectures, and the top advantage of synchronous online learning was that the location of the class was free (53.3%). In asynchronous online learning, the factors that significantly affected nursing students’ learning satisfaction were cognitive presence (β=.60, p<.001) and emotional presence (β=.25, p<.001). These variables accounted for 56% of their learning satisfaction (F=54.12, p<.001). Similarly, cognitive presence (β=.64, p<.001) and emotional presence (β=.21, p=.001) in synchronous online learning, were the factors cited for significantly affecting learning satisfaction. The explanatory power was 62% (F=69.19, p<.001). @*Conclusions@#In conclusion, it was found that cognitive and social presence from the learning presence factors in both asynchronous and synchronous online learning influence and enhance nursing students’ learning satisfaction. Therefore, these results provide important data for future online class design in nursing education.

The Relationship Between Levels of Serum Testosterone and Prostate-specific Antigen in Healthy Men: An Integrative Review

Purpose@#The purpose of this study was to review primary research exploring the correlations between the levels of serum testosterone and the prostate-specific antigen (PSA) in healthy men without prostate diseases. @*Methods@#An integrative review was conducted using the Whittemore & Knafle (2005) framework. The keywords, ‘testosterone & prostate-specific antigen’, ‘testosterone & PSA’ and ‘healthy men’ were used to search peer-reviewed publications in six databases. Among 1,959 searched articles, eleven articles were selected after excluding articles that do not meet inclusion criteria. Literature quality was moderate (Level 3). @*Results@#As a result of this study, it was confirmed through the nine articles that healthy adult men showed no significant correlation between the serum testosterone and the PSA. Conversely, two articles presented that the serum PSA correlate positively with the testosterone. In particular, it is inferred that the effect of the serum testosterone and the PSA secreted into a 24-hour circadian rhythm with different amplitudes and slopes would have had great influence. However, it does not consider the factors affecting the testosterone and the PSA, such as race, liver disease, and BMI, so there is insufficient empirical data to clearly explain the relationship between the testosterone and the PSA. @*Conclusion@#The correlation between the serum testosterone and the PSA in healthy adult men is insignificant in relation to the circadian rhythm of the testosterone and the PSA secretion. It is that a large-scale study including various influencing factors using new biochemical indicators such as pro PSA be conducted in the future.

An Integrative Review on Alterations of Sleep after Cataract Surgery

PURPOSE: The purpose of this study was to review previous literature with an aim to explore the sleep disturbance level after a patient undergoes cataract surgery using an integrative review. METHODS: We used the key words, ‘cataract surgery’, ‘sleep’, and ‘intraocular lens’ to find peer-reviewed publications in seven databases. Among 450 searched articles, eight articles were selected after exclusion of articles that did not meet the criteria. RESULTS: Five of the articles submitted that subjective sleep quality of the patients with blue-filtering intraocular lens (BF-IOL) implant improved as compared to that before surgery. The change of saliva melatonin concentration after BF-IOL implant did not coincide in two of the articles. Two of the articles reported an increased level of intrinsically photosensitive retinal ganglion cells response after BF-IOL implantation. CONCLUSION: The published studies stated that BF-IOL implant did not have any negative impact on quality of sleep among cataract patients suffering with poor sleep. Rregardless of intraocular lens type, cataract surgery may increase photoreception of intrinsically photosensitive retinal ganglion cells one year after surgery although the mechanism was not clear. It is necessary to identify various factors influencing the quality of sleep such as gender and activities among cataract patients with BF-IOL implant in the future.

A Qualitative Content Analysis of Experiences on Concept Mapping for Pathophysiology in Nursing Students

PURPOSE: The purpose of this study was to explore the experiences of nursing students in Korea who used concept mapping for understanding pathophysiology. METHODS: The data were collected using an open-ended questionnaire from 83 sophomore nursing students after studying concept mapping in pathophysiology class. Each group consisted of five nursing students submitting four concept maps regarding cell injury, inflammation, infection, and neoplasm. After familiarity with concept mapping, the participants wrote their experiences anonymously on sheets of paper. The submitted materials were analyzed via qualitative content analysis. RESULTS: The collected materials were classified into 3 themes, 8 categories, and 18 subcategories. Three themes emerged: (1) awareness of capabilities, (2) difficulties of completion, and (3) benefits of application. CONCLUSION: The study revealed that participants experienced self-capabilities, and the difficulties and benefits of concept mapping. Concept mapping also provided the opportunity for nursing students to realize communication skill improvement by active group discussion within a group.

Predictive Factors for City Dwellers' Attitudes toward Death with Dignity / 한국호스피스완화의료학회지

PURPOSE: This correlation study was performed to examine Korean adults' perceptions and attitudes towards death with dignity and the withdrawal of life sustaining treatment and to identify factors that predict their attitude towards death with dignity. METHODS: The study was conducted using convenience sampling of 291 adults from three towns of a metropolitan city in Korea. Data were collected using structured questionnaires which surveyed people's perception about and attitudes towards withdrawal of life sustaining treatment and scaled their attitude towards death with dignity. Data were analyzed by using descriptive statistics, Pearson correlation coefficients and multiple regression. RESULTS: The attitude towards the withdrawal of life sustaining treatment and death with dignity showed a significant positive correlation (r=0.49, P<0.001). For attitudes towards death with dignity, significant predictors were attitudes towards the withdrawal of life sustaining treatment, age, religion, a proper withdrawal process and advanced medical directives, which explained 49.3% of total variance. CONCLUSION: The results of this study may contribute to development of a new medical decision-making system including nurses' appropriate roles in the process of withdrawing life sustaining treatment and advanced medical directives.

Effects of Treadmill Exercise on the Recovery of Dopaminergic Neuron Loss and Muscle Atrophy in the 6-OHDA Lesioned Parkinson's Disease Rat Model

This study was to determine the effect of exercise on the recovery of dopaminergic neuron loss and muscle atrophy in 6-OHDA-induced hemi Parkinson's disease model. Exercise was loaded twice per day for 30 minutes each time, at 5 days after 6-OHDA lesioning and continued for 16 days using a treadmill. Exercise significantly increased the number of tyrosine hydroxylase positive neuron in the lesioned substantia nigra and the expression level of tyrosine hydroxylase in the striatum compared with the control group. To examine which signaling pathways may be involved in the exercise, the phosphorylation of GSK3beta and ERK were observed in the striatum. In the control group, basal level of GSK3beta phosphorylation was less than in both striatum, but exercise increased it. ERK phosphorylation decreased in the lesioned striatum, but exercise recovered it. These findings suggest that exercise inactivates GSK3beta by phosphorylation which may be involved in the neuroprotective effect of exercise on the 6-OHDA-induced cell death. In the exercise group, weight, and Type I and II fiber cross-sectional area of the contralateral soleus significantly recovered and expression of myosin heavy chain and Akt and ERK phosphorylation significantly increased by exercise. These results suggest that exercise recovers Parkinson's disease induced dopaminergic neuron loss and contralateral soleus muscle atrophy.

Effect of DHEA on Recovery of Muscle Atrophy Induced by Parkinson's Disease

PURPOSE: The purpose of this study was to determine the effect of dehydroepiandrosterone (DHEA) on recovery of muscle atrophy induced by Parkinson's disease. METHODS: The rat model was established by direct injection of 6-hydroxydopamine (6-OHDA, 20 microg) into the left striatum using stereotaxic surgery. Rats were divided into two groups; the Parkinson's disease group with vehicle treatment (Vehicle; n=12) or DHEA treatment group (DHEA; n=22). DHEA or vehicle was administrated intraperitoneally daily at a dose of 0.34 mmol/kg for 21 days. At 22-days after DHEA treatment, soleus, plantaris, and striatum were dissected. RESULTS: The DHEA group showed significant increase (p<.01) in the number of tyrosine hydroxylase (TH) positive neurons in the lesioned side substantia nigra compared to the vehicle group. Weights and Type I fiber cross-sectional areas of the contralateral soleus of the DHEA group were significantly greater than those of the vehicle group (p=.02, p=.00). Moreover, extracellular signal-regulated kinase (ERK) phosphorylation significantly decreased in the lesioned striatum, but was recovered with DHEA and also in the contralateral soleus muscle, Akt and ERK phosphorylation recovered significantly and the expression level of myosin heavy chain also recovered by DHEA treatment. CONCLUSION: Our results suggest that DHEA treatment recovers Parkinson's disease induced contralateral soleus muscle atrophy through Akt and ERK phosphorylation.

PURPOSE: The purpose of this study was to determine the effect of Dehydroepiandrosterone (DHEA) administration alone or exercise combined with DHEA before steroid treatment on rat hindlimb muscles. METHODS: Male Sprague-Dawley rats were assigned to one of three groups: a steroid group (S, n=10) that had no treatment for 7 days before steroid treatment; a DHEA-steroid group (DS, n=8) that had 0.34 mmol/kg/day DHEA injection once a day for 7 days before steroid treatment and an exercise?steroid group (EDS, n=9) that ran on the treadmill combined with 0.34 mmol/kg/day DHEA injection for 7 days before steroid treatment. At 15 days all rats were anesthetized and soleus, plantaris and gastrocnemius muscles were dissected. Body weight, food intake, muscle weight, myofibillar protein content and cross-sectional area of the dissected muscles were determined. RESULTS: The DS group showed significant increases (p<.05) as compared to the steroid group in body weight, and muscle weight of gastrocnemius muscles. The EDS group showed significant increases (p<.05) as compared to the S group in body weight, muscle weight, myofibrillar protein content, and Type II fiber cross-sectional area of soleus, plantaris and gastrocnemius muscles. CONCLUSION: Exercise combined with DHEA administration before steroid treatment prevents steroid induced muscle atrophy, with exercise combined with DHEA administration being more effective than DHEA administration alone in preventing muscle atrophy.

The Review on Characteristics, Pathophysiology and Risk Factors of Irritable Bowel Syndrome / 재활간호학회지

PURPOSE: Irritable bowel syndrome (IBS) is frequently yet little understood disease. Review was performed to promote understanding on the characteristics, pathophysiology, and risk factors of IBS. CONTENT: IBS is characterized by abdom in women and people with higher educational and social background, but there are some controversies. IBS is diagnosed by the Rome II or Manning criteria after excluding organic gastrointestinal diseases. The pathophysioloy is explained by abnormal control mechanism of central and enteric nervous system. Mucosal immunity, secretions, and neurotransmitter are also associated with the hypersensitivity and motility change of bowel function. Stress is known as a major triggering factor and contributed to symptoms. Other risk factors are genetic elements, childhood experiences, inflammation, anxiety, depression, diet, and sleep disorders.
