RESUMEN
Background/Aims@#Previous studies have revealed that glucagon-like peptide-1 receptor agonist (GLP-1RA) and thiazolidinedione (TZD) can improve nonalcoholic fatty liver disease (NAFLD) or nonalcoholic steatohepatitis (NASH). However, comprehensive research comparing the effects of GLP-1RA and TZD is limited. Thus, this study aimed to compare the effects of GLP-1RA and TZD on NAFLD or NASH through a network meta-analysis. @*Methods@#The PubMed, Embase, Web of Science, and Scopus databases were searched for randomized controlled trials (RCTs) that explored the efficacy of GLP-1RAs or TZDs in adult patients with NAFLD or NASH. The outcomes were liver biopsy-based (NAFLD activity score [NAS], fibrosis stage, and NASH resolution), noninvasive technique-based (liver fat content on proton magnetic resonance spectroscopy [1H-MRS] and controlled attenuation parameter [CAP]), biological, and anthropometric indicators. A random effects model was used to calculate the mean difference (MD) and relative risk with 95% confidence interval (CI). @*Results@#Twenty-five RCTs with 2,237 overweight or obese patients were included. GLP-1RA was significantly superior in reducing liver fat content evaluated using 1H-MRS (MD –2.42, 95% CI –3.84 to –1.00), body mass index (MD –1.60, 95% CI –2.41 to –0.80), and waist circumference (MD –4.89, 95% CI –8.17 to –1.61) than TZD. In liver biopsy-based evaluation and liver fat content assessment using CAP, GLP-1RA tended to surpass TZD, albeit not significantly. Sensitivity analysis showed consistent results with the main results. @*Conclusions@#Compared with TZD, GLP-1RA had better effects on liver fat content, body mass index, and waist circumference in overweight or obese patients with NAFLD or NASH.
RESUMEN
Purpose@#Sepsis is one of the most common causes of death after surgery. Several conventional scoring systems have been developed to predict the outcome of sepsis; however, their predictive power is insufficient. The present study applies explainable machine-learning algorithms to improve the accuracy of predicting postoperative mortality in patients with sepsis caused by peritonitis. @*Methods@#We performed a retrospective analysis of data from demographic, clinical, and laboratory analyses, including the delta neutrophil index (DNI), WBC and neutrophil counts, and CRP level. Laboratory data were measured before surgery, 12–36 hours after surgery, and 60–84 hours after surgery. The primary study output was the probability of mortality.The areas under the receiver operating characteristic curves (AUCs) of several machine-learning algorithms using the Sequential Organ Failure Assessment (SOFA) and Simplified Acute Physiology Score (SAPS) 3 models were compared.‘SHapley Additive exPlanations’ values were used to indicate the direction of the relationship between a variable and mortality. @*Results@#The CatBoost model yielded the highest AUC (0.933) for mortality compared to SAPS3 and SOFA (0.860 and 0.867, respectively). Increased DNI on day 3, septic shock, use of norepinephrine therapy, and increased international normalized ratio on day 3 had the greatest impact on the model’s prediction of mortality. @*Conclusion@#Machine-learning algorithms increase the accuracy of predicting postoperative mortality in patients with sepsis caused by peritonitis.
RESUMEN
Purpose@#Survivors of childhood leukemia are at risk of growth impairment due to intensive chemotherapy and radiation treatments. This study investigated the auxological and biochemical characteristics of childhood leukemia survivors diagnosed with growth hormone deficiency (GHD) and the changes in these parameters after 1 year of growth hormone (GH) treatment. @*Methods@#A total of 24 children diagnosed with GHD after leukemia treatment was analyzed. Clinical and biochemical data were collected retrospectively at leukemia diagnosis, GHD diagnosis, and 1 year after GH treatment. Standard deviation score (SDS) was calculated based on the age- and gender-adjusted population. @*Results@#Of the 24 children included in this study, 19 received GH treatment. The median age at GHD diagnosis was 12.3 years, and the median delay in bone age was 1.46 years. Height SDS decreased from -0.69 at leukemia diagnosis to -2.58 at GHD diagnosis (P<0.001). The change in height SDS with and without GH for 1 year was 0.35 and -0.21, respectively (P=0.044). In regression analyses, higher height SDS at GHD diagnosis and a smaller decrease of the height SDS between leukemia and GHD diagnoses were positively correlated with height SDS after GH treatment. @*Conclusion@#GH treatment could be beneficial and safe for improving height in childhood leukemia survivors with GHD. Height SDS at GHD diagnosis and reduction of height SDS between leukemia and GHD diagnosis could be potential factors in predicting the therapeutic effects. Close auxological monitoring is recommended for any childhood leukemia survivors who experience posttreatment height decline.
RESUMEN
Abstract Objective: To analyze aspects of sexual life and fertility desire among 46, XY DSD people, including those who changed their gender. Methods: It is a cross-sectional study including 127 adults (> 16 years of age) with 46, XY DSD (83 females; 44 males) from a Single Brazilian Tertiary-Care Medical Center. Results: Sexual fantasies and masturbation were more frequent in 46, XY DSD males, whereas orgasm and sexual life satisfaction were similar in both genders. More 46, XY DSD men than women had a long-term romantic relationship. 46, XY DSD women with prenatal androgen exposure reported more fear of being romantically rejected. External genitalia appearance at birth did not impact the sexuality of 46, XY DSD women after surgical genital treatment had been completed. Overall, the sexual life was similar between 46, XY men assigned as males and those who changed to the male gender. Regarding sexual orientation, most self-reported as heterosexual (91% and 92% of women and men, respectively). The desire for fertility had a similar prevalence in both genders, but more women than men considered infertility a barrier to a long-term romantic relationship. Twelve individuals (7 males) had children; 10 out of 12 have adopted children. Conclusion: Fertility desire was shared among 46, XY DSD people, regardless of gender. Prenatal androgen exposure reduced the desire for motherhood in 46, XY women. 46, XY DSD people who changed from female to male gender presented similar sexual parameters as those assigned as males. Among females, virilized genitalia at birth did not affect sexuality once the surgical treatment is completed.
RESUMEN
Purpose@#Numerous studies have reported the effects of interrupting prolonged sitting with aerobic exercise on vascular and postprandial function, but the effects of resistance exercise for interrupting prolonged sitting remain unclear. We tested the hypothesis that intermittent resistance activity breaks would attenuate prolonged sittinginduced vascular and postprandial metabolic dysfunction. @*Methods@#Fourteen healthy adults (age, 24±2 years; body mass index, 22.0±2.4 kg/m2 ) completed two trials in a randomized cross-over design. During a 4-hour sitting after a high-fat meal, the participants underwent either resistance activity (RA) with 10 repetitions of five exercises every hour or uninterrupted sitting as a control trial (SIT). Plasma glucose, triglycerides, and brachial artery blood pressure, along with blood flow and shear rate in the superficial femoral artery and carotid artery were measured at baseline and every hour during the 4-hour sitting period. Brachial artery flow-mediated dilation (FMD) was measured at baseline, 2 hours, and 4 hours after the start of the sitting. @*Results@#Plasma glucose and triglycerides increased after a high-fat meal in both RA and SIT groups without a significant interaction effect. In addition, while SIT group decreased brachial artery FMD (7.2%±2.0% to 6.5%±2.7% to 5.1%±2.6%), RA did not attenuate a decrease in FMD (7.6%±3.4% to 7.3%±3.1% to 6.7%±2.7%, interaction p=0.581). @*Conclusion@#Our findings indicate that interrupting prolonged sitting with intermittent RA did not attenuate the negative effects of sitting on vascular function and postprandial metabolism in young healthy adults.
RESUMEN
Purpose@#Regular aerobic exercise improves exercise capacity and quality of life in children with congenital heart disease (CHD), but it remains unclear whether aerobic exercise would improve vascular function in children with CHD. We tested the hypothesis that acute bout of virtual reality (VR) exergame would improve vascular function in children with CHD. @*Methods@#In a single-arm study, eight children (age, 9±1 years; five males) with CHD participated in VR exergame (30 minutes at 40% of heart rate reserve) using a stationary cycle ergometer with a head mount display. Endothelial function and arterial stiffness as surrogate markers of vascular function were assessed via reactive hyperemia index (RHI) and augmentation index (AIx) using peripheral arterial tonometry at baseline and 30 minutes after VR exergame. @*Results@#Compared to baseline, VR exergame improved in RHI (1.08 [0.96–1.30] to 1.16 [1.09–1.36], p＜ 0.05) and natural log transformed RHI (0.07 [−0.04–0.26] to 0.15 [0.09–0.31], p＜ 0.05). However, no significant changes were observed for decrease AIx (−1.00 [−9.00–9.50] to −7.00 [−14.00–8.75], p=0.547) and AIx@75 (−6.50 [9.75–3.50] to −4.50 [−13.00–4.50], p=0.735) (all index values are reported as median [interquartile range]). @*Conclusion@#These findings suggest that a single bout of VR exergame has the potential to improve vascular endothelial function in children with CHD.
RESUMEN
The purpose of this study is to analyze hazardous substances that can be eluted from polymer instruments used in dentistry in vitro. In the study, Dental polymer based hand instruments were eluted with exaggerated conditions (4 g/20 mL, 50 ℃, 72 h) in accordance with ISO 10993-12:2021. Appearance, pH, potassium permanganate-reducible substances, UV spectrum, residue on evaporation, and heavy metals. The additional test was performed by GC/MS for Bisphenol A. As a result, the extracts of 10 types of dental polymer based hand instruments showed colorless, transparent, and no foreign substances. pH was between 0.9 to 1.7. the difference in potassium permanganate consumption was 0.1 to 0.5 mL. The absorbance (220~350 nm) was less than 0.05, and the evaporation residue was 0.5 to 0.8 mg. Concentration of Pb was less than 4 ppm, and BPA was not detected in all extracts. It was confirmed that the 10 types of polymer materials used in this study did not exceed the regulated amount of hazardous substances set by the domestic regulatory body (Ministry of Food and Drug Safety (MFDS), Korea). These results suggest that these polymers could be safely used in the oral cavity as dental instruments.
RESUMEN
Objectives@# Based on the results from the Korean Total Diet Study (KTDS), the sodium (Na) and potassium (K) intake of Koreans were estimated and compared with intake estimates from the Food & Nutrient Database (FNDB), as in the Korea National Health and Nutrition Examination Survey (KNHANES) to verify the validity of these estimates. @*Methods@# One hundred and thirty-four representative foods (RFs) covering 92.5% of the total food intake of Koreans were selected, and 228 pairs of corresponding ‘RF x representative cooking method’ were derived by reflecting the methods used mainly in terms of frequency and quantity in their cooking.RF samples were collected from three cities with a larger population size in three regions (nine cities) nationwide, and six composite samples were made for each RF, considering its regional and/or seasonal characteristics. One thousand three hundred and sixty-eight ‘RF x representative cooking method’ pair samples were prepared, and the Na and K contents were assessed using inductively coupled plasma atomic emission spectrometry (ICP-MS). The Na and K intake of the Korean population was estimated by linking the content with the food intake data from the 7th KNHANES. @*Results@# The mean Na and K intake of Koreans were 2,807.4 mg and 2,335.0 mg per person per day, respectively. A comparison with the Na and K intake from KNHANES, including only RFs of KTDS, showed comparable results with less than 5% variation. While the contribution and ranking of food items to Na intake were similar between KNHANES and KTDS, there were differences in K intake.This was attributed to the large discrepancies in the K content of rice and coffee between KTDS results and the values in the 9th Revision of the National Food Composition Table used in KNHANES. @*Conclusions@# The Na and K intake of Koreans estimated based on the KTDS, which performed nutrient analysis on samples prepared to a ‘table-ready’ state using foods of the representative collection, was similar and comparable with that of KNHANES. This supports the validity and usefulness of FNDB-based nutrient intake estimation at the population level. The list of nutrients studied in KTDS is expected to be expanded, allowing for intake estimation of nutrients with currently insufficient or absent information in the FNDBs in use.
RESUMEN
Objective@#This study aimed to investigate the prevalence and status of dyslipidemia management among South Korean adults, as performed by the Korean Society of Lipid and Atherosclerosis under the name Dyslipidemia Fact Sheet 2022. @*Methods@#We analyzed the lipid profiles, age-standardized and crude prevalence, management status of hypercholesterolemia and dyslipidemia, and health behaviors among Korean adults aged ≥20 years, using the Korea National Health and Nutrition Examination Survey data between 2007 and 2020. @*Results@#In South Korea, the crude prevalence of hypercholesterolemia (total cholesterol ≥240 mg/dL or use of a lipid-lowering drug) in 2020 was 24%, and the age-standardized prevalence of hypercholesterolemia more than doubled from 2007 to 2020. The crude treatment rate was 55.2%, and the control rate was 47.7%. The crude prevalence of dyslipidemia (more than one out of three conditions [low-density lipoprotein-cholesterol ≥160 or the use of a lipid-lowering drug, triglycerides ≥200, or high-density lipoprotein-cholesterol (men and women) <40 mg/ dL]) was 40.2% between 2016 and 2020. However, it increased to 48.2% when the definition of hypo-high-density lipoprotein-cholesterolemia in women changed from <40 to <50 mg/dL. @*Conclusion@#Although the prevalence of hypercholesterolemia and dyslipidemia has steadily increased in South Korea, the treatment rate remains low. Therefore, continuous efforts are needed to manage dyslipidemia through cooperation between the national healthcare system, patients, and healthcare providers.
RESUMEN
Objective@#We aimed to assess the level of public awareness regarding dyslipidemia and its management among the Korean population. @*Methods@#We conducted a web- or mobile-based survey study targeting the general population, using various recruitment methods, between July 25, 2022 and August 26, 2022.The questionnaire consisted of 12 questions designed to collect demographic information and evaluate participants’ awareness and knowledge about dyslipidemia. @*Results@#In total, 2,882 participants who completed the survey were included in the analysis.Among the participants, a substantial majority (89.1%) were familiar with the concepts of “good cholesterol” and “bad cholesterol,” while a comparatively lower percentage (just 46.7%) were acquainted with the term “dyslipidemia.” Noticeable variations in understanding were observed when examining specific aspects of dyslipidemia management, including diet, exercise, and pharmacotherapy. @*Conclusion@#The results of this survey underscore the significance of enhancing public awareness about dyslipidemia within the context of health literacy, demonstrating the necessity for a more comprehensive approach that includes education and policymaking to effectively manage dyslipidemia.
RESUMEN
Background@#We sought to identify the influence of prepregnancy glucose levels on obstetric complications in subsequent pregnancy. @*Methods@#Women in Republic of Korea who had given birth between January 1st, 2007 and December 31st, 2010 were enrolled. The database of the Health Insurance Review and Assessment Service and data from a national health screening program for infants and children were used. Subjects were divided into seven groups according to their fasting glucose levels. @*Results@#59,619 women were included for analysis, and 10.4%, 13.7%, 19.1%, 21.5%, 16.0%, 11.6%, and 7.5% women had glucose levels of 100 mg/dL. Each 5 mg/dL increase in prepregnancy fasting glucose levels was associated with increased risk of gestational diabetes and macrosomia in subsequent pregnancy. Adjusted risk ratio for gestational diabetes per standard deviation prepregnancy glucose > 100 mg/dL was 2.015 (95% confidence interval, 1.649–2.462) and for macrosomia an adjusted risk ratio 1.389 (95% confidence interval, 1.147–1.682). @*Conclusion@#Higher prepregnancy glucose level within normal range was related to gestational diabetes and macrosomia in following pregnancy. Our results may aid in the identification of women at future risk of obstetric complications and may guide to stratify women into normal and intensified care.Tweetable abstractHigher prepregnancy glucose in normal range is associated with gestational diabetes and macrosomia.
RESUMEN
Background@#Texture analysis may capture subtle changes in the gray matter more sensitively than volumetric analysis. We aimed to investigate the patterns of neurodegeneration in semantic variant primary progressive aphasia (svPPA) and Alzheimer’s disease (AD) by comparing the temporal gray matter texture and volume between cognitively normal controls and older adults with svPPA and AD. @*Methods@#We enrolled all participants from three university hospitals in Korea. We obtained T1-weighted magnetic resonance images and compared the gray matter texture and volume of regions of interest (ROIs) between the groups using analysis of variance with Bonferroni posthoc comparisons. We also developed models for classifying svPPA, AD and control groups using logistic regression analyses, and validated the models using receiver operator characteristics analysis. @*Results@#Compared to the AD group, the svPPA group showed lower volumes in five ROIs (bilateral temporal poles, and the left inferior, middle, and superior temporal cortices) and higher texture in these five ROIs and two additional ROIs (right inferior temporal and left entorhinal cortices). The performances of both texture- and volume-based models were good and comparable in classifying svPPA from normal cognition (mean area under the curve [AUC] = 0.914 for texture; mean AUC = 0.894 for volume). However, only the texture-based model achieved a good level of performance in classifying svPPA and AD (mean AUC = 0.775 for texture; mean AUC = 0.658 for volume). @*Conclusion@#Texture may be a useful neuroimaging marker for early detection of svPPA in older adults and its differentiation from AD.
RESUMEN
Background@#Data on the status of long-term follow-up (LTFU) care for childhood cancer survivors (CCSs) in Korea is lacking. This study was conducted to evaluate the current status of LTFU care for CCSs and relevant physicians’ perspectives. @*Methods@#A nationwide online survey of pediatric hematologists/oncologists in the Republic of Korea was undertaken. @*Results@#Overall, 47 of the 74 board-certified Korean pediatric hematologists/oncologists currently providing pediatric hematology/oncology care participated in the survey (response rate = 63.5%). Forty-five of the 47 respondents provided LTFU care for CCSs five years after the completion of primary cancer treatment. However, some of the 45 respondents provided LTFU care only for CCS with late complications or CCSs who requested LTFU care. Twenty of the 45 respondents oversaw LTFU care for adult CCSs, although pediatric hematologists/ oncologists experienced more difficulties managing adult CCSs. Many pediatric hematologists/oncologists did not perform the necessary screening test, although CCSs had risk factors for late complications, mostly because of insurance coverage issues and the lack of Korean LTFU guidelines. Regarding a desirable LTFU care system for CCSs in Korea, 27 of the 46 respondents (58.7%) answered that it is desirable to establish a multidisciplinary CCSs care system in which pediatric hematologists/oncologists and adult physicians cooperate. @*Conclusion@#The LTFU care system for CCS is underdeveloped in the Republic of Korea. It is urgent to establish an LTFU care system to meet the growing needs of Korean CCSs, which should include Korean CCSs care guidelines, provider education plans, the establishment of multidisciplinary care systems, and a supportive national healthcare policy.
RESUMEN
Background@#and Purpose Physical frailty is known to be closely associated with cognitive impairment and to be an early sign of Alzheimer’s disease. We aimed to understand the characteristics of physical frailty and define factors associated with physical frailty in subjects with subjective cognitive decline (SCD) by analyzing amyloid data. @*Methods@#We prospectively enrolled subjects with SCD from a cohort study to identify predictors for the clinical progression to mild cognitive impairment or dementia from SCD (CoSCo). All of the subjects underwent brain magnetic resonance imaging, and brain amyloid positron-emission tomography (PET) to detect amyloid beta plaques. Self-reported exhaustion, handgrip strength, and gait speed were used to measure physical frailty. @*Results@#Of 120 subjects with SCD, 26 (21.7%) were amyloid-positive in PET. Female (odds ratio [OR]=3.79, p=0.002) and amyloid-PET-positive (OR=3.80, p=0.008) subjects with SCD were at high risks of self-reported exhaustion. Amyloid PET positivity (OR=3.22, p=0.047) and high burden from periventricular white-matter hyperintensity (OR=3.34, 95% confidence interval=1.18–9.46, p=0.023) were significantly associated with a weaker handgrip. The subjects with SCD with self-reported exhaustion and weaker handgrip presented with lower cognitive performance in neuropsychological tests, especially for information processing speed and executive function. Subjects with a slower gait performed worse in visual memory function tests. @*Conclusions@#Amyloid PET positivity was associated with a higher risk of self-reported exhaustion and weaker handgrip in subjects with SCD. The subjects with SCD and physical frailty also performed worse in neuropsychological tests.
RESUMEN
Purpose@#A retrospective descriptive study was performed to develop strategies to manage or prevent pressure ulcers in patients with severe trauma being cared for in the trauma intensive care unit (TICU). @*Methods@#Study data was compiled from 315 patients with severe trauma (injury severity score ≥ 15) who were admitted to a general hospital from January 1, 2020, to February 28, 2021 and were being cared for in the TICU. For patients with pressure ulcers, the characteristics and associated factors of pressure ulcers were examined. @*Results@#There were 42 severe trauma patients (13.3%) with pressure ulcers, of which, 50.0% of cases occurred at the site of the coccyx. In 50% of patients, Stage 2 pressure ulcers were observed. The mean onset day of pressure ulcers was 9.74 days after admission. The occurrence of diabetes, critical care triage score, length of stay in intensive care, death, shock, dialysis, ventilator application, endotracheal intubation, peripheral insertion central catheter insertion, A-line insertion, body protector application, sedatives, blood pressure boosters, nasal cannula, high-flow oxygenators, oxygen tip application, drainage insertion, nasogastric tube nutrition, and ventilator application period were investigated. Logistic regression analysis revealed that the influencing factors for the development of pressure ulcers were endotracheal intubation, length of stay in the TICU, and age, in that order. @*Conclusion@#By identifying the characteristics and risk factors associated with pressure ulcers in patients with severe trauma, strategies can be developed to better prevent or manage pressure ulcers in the future.

However, it increased to 48.2% when the definition of hypo-HDL-cholesterolemia in women changed from <40 to <50 mg/dL. @*Conclusion@#Although the prevalence of hypercholesterolemia and dyslipidemia has steadily increased in South Korea, the treatment rate remains low. Therefore, continuous efforts are needed to manage dyslipidemia through cooperation between the national healthcare system, patients, and healthcare providers.
RESUMEN
Purpose@#This retrospective study aimed to determine the number of times the ultrasound-guided attenuation parameter (UGAP) should be measured during the evaluation of hepatic steatosis. @*Methods@#Patients with suspected nonalcoholic fatty liver disease who underwent two UGAP repetition protocols (six-repetition [UGAP_6] and 12-repetition [UGAP_12]) and measurement of the controlled attenuation parameter (CAP) using transient elastography between October 2020 and June 2021 were enrolled. The mean attenuation coefficient (AC), interquartile range (IQR)/median, and coefficient of variance (CV) of the two repetition protocols were compared using the paired t test. Moreover, the diagnostic performances of UGAP_6 and UGAP_12 were compared using the area under the receiver operating characteristic (AUROC) curve, considering the CAP value as a reference standard. @*Results@#The study included 160 patients (100 men; mean age, 50.9 years). There were no significant differences between UGAP_6 and UGAP_12 (0.731±0.116 dB/cm/MHz vs. 0.734±0.113 dB/cm/MHz, P=0.156) and mean CV (7.6±0.3% vs. 8.0±0.3%, P=0.062). However, the mean IQR/median of UGAP_6 was significantly lower than that of UGAP_12 (8.9%±6.0% vs. 9.8%±5.2%, P=0.012). In diagnosing the hepatic steatosis stage, UGAP_6 and UGAP_12 yielded comparable AUROCs (≥S1, 0.908 vs. 0.897, P=0.466; ≥S2, 0.883 vs. 0.897, P=0.126; S3, 0.832 vs. 0.834, P=0.799). @*Conclusion@#UGAP had high diagnostic performance in diagnosing hepatic steatosis, regardless of the number of repetitions (six repetitions vs. 12 repetitions), with maintained reliability. Therefore, six UGAP measurements seem sufficient for evaluating hepatic steatosis using UGAP.
RESUMEN
The definition of faculty development has been refined and expanded over the past few decades, and various definitions have been used in higher education. Initially, faculty development was defined as activities that help teachers improve teaching skills, design better curricula, and improve the organizational environment for education. Since then, as the focus of faculty development has shifted from individual professors to institutional needs, faculty development is now defined as the personal and professional development of professors, clinicians, researchers, and managers to meet institutional goals, visions, and missions in social terms and moral responsibility to the community. Faculty development in medical education is universally needed to recognize and cope with widespread changes in education, including the traditional role of professors, advances in pedagogical theory, changes in learning styles, innovative curriculum models, and evaluation philosophy. However, critics have pointed out that most universities could not actively implement faculty development or accept professors’ various demands. In this paper, various reports related to faculty development are reviewed to summarize how faculty development has progressed and present future directions for accepting various opinions to improve educational excellence and the quality of health care.
RESUMEN
Purpose@#: This study aimed to compare peripheral pulse oxygen saturation (SpO2) values, measured at different monitoring sites, and arterial oxygen saturation (SaO2) of neurocritical patients. @*Methods@#: The study included 110 patients admitted to the neurosurgical intensive care unit of a university hospital. The patients’ SpO2 values were measured in their index fingers, both second toes, both earlobes, and foreheads, using the patient monitoring system. These values were compared with the standard value of SaO2 measured using a blood gas analyzer. Data were analyzed using descriptive values, Pearson’s correlation coefficients, Lin’s concordance correlation coefficients (CCC), and Bland-Altman plots.Result : Regardless of the measuring site, SpO2 was correlated with the paired measurements of SaO2 (r=.40~.60, p＜.001, CCC range=.40~.58). No significant bias in paired measurements of SpO2 and SaO2 was observed at all sites (-0.06~0.19%, p＞.05). SpO2 values at the left finger and right earlobe had the narrowest range, with a 95% limits of agreement (LOA) (left finger -3.04~2.93% and right earlobe -3.18~2.79%). SpO2 at the index finger, on the side without an arterial catheter, had a narrower range of 95% LOA than that of the opposing finger (-3.00~2.97% vs. -3.73~3.26%). @*Conclusion@#: SpO2 at the finger without an arterial catheter had the highest level of precision. This study suggests using the index finger, on the side without an arterial catheter, for pulse oximetry in neurocritical patients.
RESUMEN
Purpose@#The purpose of this study was to explore the experiences through which nurses overcame turnover intention when first joining the field. @*Methods@#Study subjects included 10 nurses, each of whom had four to six years of work experience at a general hospital. The experiences of overcoming turnover intentions were analyzed from the perspectives of beginner and experienced nurses, using qualitative contents analysis as a method of deduction. @*Results@#The subjects’ turnover intention was low, with an average score of 2.25±0.35. Five themes and 15 sub-themes were extracted from their experiences. The five themes included: “gaining an understanding of the nursing scene”, “experiencing a support system”, “being satisfied with my job”, “developing into a skilled nurse”, and “overcoming and growing”. @*Conclusion@#Subjects maintained low levels of turnover intention, and they were able handle difficulty and grow into their careers as nurses. These findings may inform the development of programs to overcome turnover intention, specifically in terms of factors affecting norvice nurses’ positive achievement factor.
