RESUMEN
Therapeutic communication, of which nonverbal communication is a vital component, is an essential skill for professional nurses. The aim of this study is to assess the possibility of incorporating computer analysis programs into nursing education programs to improve the nonverbal communication skills of those preparing to become professional nurses. In this pilot observational study, the research team developed a computer program for nonverbal communication analysis including facial expressions and poses. The video clip data captured during nursing simulation practice by 10 3rd- and 4th-grade nursing students at a university in South Korea involved two scenarios of communication with a child's mother regarding the child's pre- and post-catheterization care. The dominant facial expressions varied, with sadness (30.73%), surprise (30.14%), and fear (24.11%) being the most prevalent, while happiness (7.96%) and disgust (6.79%) were less common. The participants generally made eye contact with the mother, but there were no instances of light touch by hand and the physical distance for nonverbal communication situations was outside the typical range. These results confirm the potential use of facial expression and pose analysis programs for communication education in nursing practice.
RESUMEN
Stress is a direct or indirect cause of reduced work efficiency in daily life. It can damage physical and mental health, leading to cardiovascular disease and depression. With increased interest and awareness of the risks of stress in modern society, there is a growing demand for quick assessment and monitoring of stress levels. Traditional ultra-short-term stress measurement classifies stress situations using heart rate variability (HRV) or pulse rate variability (PRV) information extracted from electrocardiogram (ECG) or photoplethysmography (PPG) signals. However, it requires more than one minute, making it difficult to monitor stress status in real-time and accurately predict stress levels. In this paper, stress indices were predicted using PRV indices acquired at different lengths of time (60 s, 50 s, 40 s, 30 s, 20 s, 10 s, and 5 s) for the purpose of real-time stress monitoring. Stress was predicted with Extra Tree Regressor, Random Forest Regressor, and Gradient Boost Regressor models using a valid PRV index for each data acquisition time. The predicted stress index was evaluated using an R2 score between the predicted stress index and the actual stress index calculated from one minute of the PPG signal. The average R2 score of the three models by the data acquisition time was 0.2194 at 5 s, 0.7600 at 10 s, 0.8846 at 20 s, 0.9263 at 30 s, 0.9501 at 40 s, 0.9733 at 50 s, and 0.9909 at 60 s. Thus, when stress was predicted using PPG data acquired for 10 s or more, the R2 score was confirmed to be over 0.7.

Periprosthetic fracture after total elbow replacement surgery is a difficult complication to manage, especially when it comes together with implant loosening. If stem revision and internal fixation of the periprosthetic fracture are performed simultaneously, this would be a very challenging procedure. Most of total elbow replacement implants are cemented type. Cement usage at periprosthetic fracture site may interfere healing of fractured site. Authors underwent internal fixation with use of locking plate and cerclage wire for periprosthetic fracture, allogenous fibular strut bone inserted into the humerus intramedullary canal allowing the fractured site to be more stable without cement usage. At 10-month follow-up, the complete union and good clinical outcome was achieved. We present a novel technique for treating periprosthetic fracture with implant loosening after total elbow replacement surgery, using intramedullary allogenous fibula strut bone graft.
RESUMEN
STUDY DESIGN: A nationwide population-based study. PURPOSE: Osteoporotic vertebral compression fracture (OVCF) is a major public health issue. This study examined the incidence and management trends of OVCF in South Korea. OVERVIEW OF LITERATURE: The incidence rates, management trends, and patterns of OVCF differ in different parts of the world. The age-standardized OVCF incidence rate in 2015 was higher in the United States and Asia than in Europe. METHODS: A nationwide database (2012-2016) acquired from the Korean Health Insurance Review and Assessment Service was analyzed. International disease categories in the 10th revision of the International Statistical Classification of Diseases and Related Health Problems codes, medical procedure codes, and examination codes were used to identify and sort OVCF patients aged >50 years. RESULTS: There were 644,500 OVCF cases from 2012 to 2016. OVCF was most common in patients in their seventies (45%) and the number of patients increased from 117,361 in 2012 to 139,889 in 2016 (p <0.001). During 2012-2016, 8.9% of patients visited the emergency department; of those, 54.3% were hospitalized and 35% underwent magnetic resonance imaging. In OVCF treatment, bone cement augmentation rates increased from 23.4% in 2012 to 25.2% in 2016 (p <0.001), while conservative treatment rates slightly decreased from 76.5% in 2012 to 74.7% in 2016 (p <0.001). The total health insurance cost was $193,210,353.55 in 2012 and $281,968,877.65 in 2016. CONCLUSIONS: The 5-year incidence of OVCF per 100,000 persons was 852.24 cases, and 45% of OVCF in South Korea occurred in patients in their seventies. The bone cement augmentation rate and total cost of OVCF are continuously increasing.
RESUMEN
BACKGROUND: Patients with rheumatoid arthritis (RA) have higher rate of osteoporosis and vertebral fracture than individuals without RA. This study aimed to compare the outcomes of balloon kyphoplasty (KP) performed to treat osteoporotic vertebral compression fracture (OVCF) in RA patients with the outcomes in non-RA patients. MATERIALS AND METHODS: The patients who received KP for OVCF and could be followed up at least 1 year were included in the study. These patients were divided into RA group and non-RA group. For clinical outcomes, the visual analog scale for back pain (VAS-BP) and Korean version of the Oswestry Disability Index (K-ODI) were assessed before and after the procedure and at the 1-year followup. For radiological outcomes, the anterior vertebral height and change in local kyphotic angle were measured. Complications were also examined. RESULTS: Twenty three RA patients (31 vertebral bodies) and 107 non-RA patients (124 vertebral bodies) were analyzed. In two groups, postoperative VAS-BP and K-ODI decreased significantly to similar extents. There was a similar recovery of vertebral height and kyphotic angle in two groups. However, in terms of complications, adjacent segment fracture and recollapse were more frequent in the RA group than in the non-RA group. CONCLUSIONS: The use of KP to treat OVCF in RA group exhibited similar outcomes to non-RA group in terms of pain reduction, vertebral height restoration, and kyphosis correction. However, RA group had significantly higher rate of complications involving adjacent segment fracture and recollapse. Therefore, careful followup after KP in patients with RA is required to monitor for high complication rate.
RESUMEN
BACKGROUND CONTEXT: It has been reported that newly developed osteoporotic vertebral compression fractures (OVCFs) occur at a relatively high frequency after treatment. While there are many reports on possible risk factors, these have not yet been clearly established. PURPOSE: The purpose of this study was to investigate the risk factors for newly developed OVCFs after treatment by vertebroplasty (VP), kyphoplasty (KP), or conservative treatment. STUDY DESIGN/SETTING: A retrospective comparative study. PATIENT SAMPLE: One hundred thirty-two patients who had radiographic follow-up data for one year or longer among 356 patients who were diagnosed with OVCF and underwent VP, KP or conservative treatment between March 2007 and February 2016. OUTCOME MEASURES: All records were examined for age, sex, body mass index (BMI), rheumatoid arthritis and other medical comorbidities, osteoporosis medication, bone mineral density (BMD), history of vertebral and nonvertebral fractures, treatment methods used, level of fractures, and presence of multiple fracture sites. METHODS: Patients were divided into those who manifested new OVCF (Group A) and those who did not (Group B). For the risk factor analysis, student's t-tests and chi-square tests were used in univariate analysis. Multivariate logistic regression analysis was carried out on variables with a p<.1 in the univariate analysis. RESULTS: Newly developed OVCFs occurred in 46 of the 132 patients (34.8%). Newly developed OVCF increased significantly with factors such as average age (p=.047), low BMD T-score of the lumbar spine (p=.04) and of the femoral neck (p=.046), advanced age (>70 years) (p=.011), treatment by cement augmentation (p=.047) and low compliance with osteoporosis medication (p=.029). In multivariate regression analysis, BMD T-score of the lumbar spine (p=.009) and treatment by cement augmentation (p=.044) showed significant correlations with the occurrence of new OVCFs with a predictability of 71.4%. CONCLUSION: Osteoporotic vertebral compression fracture patients with low BMD T-score of the lumbar spine and those who have been treated by cement augmentation have an increased risk of new OVCFs after treatment and, therefore, require especially careful observation and attention.
