- Abstract
Financial distress can have a detrimental influence on the performance of hospitals. Hospital management needs to monitor potential financial distress effectively and know how it will respond depending on the severity of the circumstances. This study examined the multiple factors that may explain the financial distress of nonprofit hospitals during 1998 to 2001 and discussed their importance. To obtain more robust results, financial distress was assessed in 2 ways: first, financial strength index was used to incorporate 4 financial dimensions including profitability, liquidity, leverage, and physical facilities; second, cash flow (CF) was used to address the issues of accrual-based accounting in hospitals. This study finds that decrease in occupancy rate and increase in Medicaid payer mix, health maintenance organization penetration, market competition, physician supply, and percentage of the elderly are associated with increased likelihood of financial distress of urban hospitals. Increases in both Medicare and Medicaid payer mix, however, are related to higher likelihood of financial distress of rural hospitals. [ABSTRACT FROM AUTHOR]

McCue MJ and Kim TH
- Abstract
Background: Recent trends show a greater usage of variable rate debt among health care bond issues. In 2004, 63.4% of the total health care bonds issued were variable rate compared with 30.6% in 1995 (Fitch Ratings, 2005).Purpose: The purpose of this study is to gain a better understanding of the underlying factors, credit spread, issue characteristics, and issuer factors behind why hospitals and health system borrowers select variable rate debt compared with fixed rate debt.Methodology: From 2000 to 2004, this study sampled 230 newly issued tax-exempt bonds issued by acute care hospitals and health care systems that included both variable and fixed rate debt issues. Using a logistic regression model, hospitals with variable rate debt issues were assigned a value of 1, whereas hospitals with fixed rate debt issues were assigned a value of 0.Findings: This study found a positive association between bond insurance and variable rate debt and a negative association between callable feature and variable rate debt. Facilities located in certificate-of-need states that possessed higher case mix acuity, earned higher profit margins, generated higher debt service coverage, and held less debt were more likely to issue variable rate debt.Practice Implications: Overall, hospital managers and board members of hospitals possessing a strong financial performance have an interest in utilizing variable rate debt to lower their cost of capital. In addition, this outcome may also reflect that investment bankers are doing a better job in educating senior hospital management about the interest rate savings benefit of variable rate compared with fixed rate debt.

- Abstract
Study Design: A prospective cohort study.Objective: To demonstrate the changes in vitamin D status after surgery in female patients with lumbar spinal stenosis (LSS), and its correlation with surgical outcomes.Summary Of Background Data: In patients with LSS, general health including walking ability and nutritional status can be markedly improved by decompressive surgery. It can be hypothesized that such improvement may have a positive effect on their vitamin D status.Methods: In total, 31 female patients who underwent decompression and instrumented posterolateral fusion for LSS were enrolled. Serum 25-hydroxyvitamin D (25-OHD) level was measured before the surgery and at 1 year postoperative visit. According to serum 25-OHD level, patients were classified into 3 groups: (1) deficient group, when 25-OHD level was less than 20 ng/mL (< 50 nmol/L); (2) insufficient group, when 25-OHD level was between 20 to 30 ng/mL (50 nmol/L ≤ 25-OHD < 75 nmol/L); (3) and normal group, when 25-OHD level was 30 ng/mL or more (≥ 75 nmol/L). The Oswestry Disability Index (ODI) score and health-related quality of life (EQ-5D) were compared according to the level of 25-OHD at 1 year postoperatively.Results: Preoperatively, there were 20 patients in the deficient group, 11 patients in the insufficient group and no patient in the normal group. There were no differences in age, body mass index, preoperative ODI scores, preoperative EQ-5D index scores, and EQ-5D visual analogue scale scores between the 2 groups. Mean preoperative 25-OHD level was 15.8 ng/mL (range, 5.2-29.4 ng/mL) and increased to 19.5 ng/mL (range, 6.3-47.7 ng/mL) 1 year after surgery (P = 0.075). Significant increase of 25-OHD was noted only in the deficient group (P = 0.017). Postoperatively, there were 18 patients in the deficient group, 8 patients in the insufficient group, and 5 patients in the normal group. In the postoperative deficient group, postoperative ODI scores and EQ-5D index scores showed significantly worse outcomes than those in the other groups. The changes in serum 25-OHD level were significantly correlated with the changes in ODI scores (r = -0.580; P = 0.001) and with the changes in EQ-5D index scores (r = 0.379; P = 0.035). In all the groups, postoperative ODI scores (r = -0.665; P < 0.001) and EQ-5D index scores (r = 0.601; P < 0.001) were significantly correlated with postoperative 25-OHD level.Conclusion: Vitamin D deficiency was common in patients with LSS. However, vitamin D status was improved after decompressive surgery, and postoperative 25-OHD level was significantly correlated with surgical outcomes. [ABSTRACT FROM AUTHOR]- Published

- Abstract
Introduction: Recreating the philtral ridge and restoring orbicularis oris muscle continuity in cleft patients is a challenging task. Our muscle to sub-dermis technique introduces an effective method for achieving the desired philtral ridge reconstruction., Method: From August 2015 to July 2023, a retrospective study was conducted with a follow-up period of at least 6 months. This procedure involved a suture technique using muscle-to-sub-dermis sutures. Measurements of philtral projection were taken at two distinct points: one above the cupid's bow and the other at the mid-philtral level. In the comparative analysis of philtral ridges between the cleft and non-cleft sides, the root mean square (RMS) projection value was assessed. Additionally, an analysis of the restoration of the orbicularis oris muscle included the use of color mapping from the mid-sagittal plane and covered seven different points across three distinct horizontal planes: below subnasale, at the mid-philtral level, and above the cupid's bow., Results: Total 134 patients were included with a 37.8-month follow-up(SD 9.4). Philtral side projection was well-maintained, measuring -0.36(0.43)mm, -0.24(0.49)mm on the classical group vs. 0.23(0.29)mm, 0.20(0.21)mm on the muscle to sub-dermis group(p=0.001). The RMS projection value was 0.57(0.46) vs. 0.14(0.046), indicating greater symmetry in the muscle to sub-dermis group, with no difference in sagittal vector analysis of the orbicularis oris muscle between normal and cleft sides., Conclusion: A suturing technique utilizing muscle to sub-dermis sutures has shown promising results in philtral projection and dimple formation. This improvement can be attributed to the combined effect of sub-dermis and less muscle sutures., Competing Interests: Financial Disclosure Statement: The authors declare no financial conflicts of interest or sources of funding regarding any of the products, devices, or drugs mentioned in this manuscript., (Copyright © 2024 by the American Society of Plastic Surgeons.)

- Abstract
Objective: Assess the significance of enlarged lateral lymph nodes (LLN) for disease recurrence, metastasis, and organ preservation in patients with rectal cancer., Background: Optimal treatment of rectal adenocarcinoma involving LLN is subject to debate., Methods: A post hoc analysis of the OPRA trial, a multicenter study of patients with rectal cancer treated with total neoadjuvant therapy (TNT) followed by total mesorectal excision or watch-and-wait management. We analyzed the association of visible LLN (LLN+), LLN≥7 mm (short axis) on baseline MRI, and LLN≥4 mm on restaging MRI with recurrence, metastasis, and rectum preservation., Results: At baseline, 57 out of 324 (18%) patients had LLN+. In 30 (53%) of 57 patients with LLN+ on baseline MRI, the LLN disappeared after TNT. Disease recurrence in LLN was rare (3.5% of patients with LLN+ and 0.4% of patients with LLN-). All patients with recurrence in LLN also had distant metastasis. The rate of organ preservation was significantly lower in patients with LLN≥4 mm on restaging MRI (P=0.013). We found no significant differences in rates of local recurrence or metastasis between patients with LLN+ vs. LLN- and in patients with LLN≥7 vs.<7 mm on baseline MRI. LLN dissection was performed in 3 patients; 2 of them died of distant metastasis., Conclusions: LLN involvement is not associated with disease recurrence or metastasis, but persistence of LLN≥4 mm after TNT is negatively associated with rectum preservation in patients with locally advanced rectal cancer treated with TNT. Dissection of lateral nodes likely benefits few patients., Competing Interests: Conflicts of interest: Martin R. Weiser receives an honorarium from Precisca. J.

- Abstract
Objectives: This study aimed to unidimensionally measure procedural pain at each percutaneous vertebroplasty (PVP) stage and evaluate the effectiveness of paravertebral nerve block (PVNB) in reducing procedural pain., Methods: A retrospective study of prospectively collected data was conducted on 66 patients who underwent PVP for osteoporotic vertebral compression fractures. The patients were divided into 2 groups: group A (fluoroscopic-guided PVNB; 5 cm 3 of 0.75% ropivacaine on each side) and group B (local anesthesia). To investigate procedural pain associated with PVP, the visual analog scale score was assessed at each surgical stage: before the incision (stage 1), transpedicular approach (stage 2), and polymethylmethacrylate cement injection (stage 3). After the procedure, patients were asked about their surgical experience and satisfaction using the Iowa Satisfaction with Anesthesia Scale. Periprocedural complications were also recorded., Results: A total of 63 patients (78.65 y of age) were finally enrolled: 30 from group A and 33 from group B. In both groups, a significant ≥2-point increase in procedural pain was observed during PVP compared with that during stage 1 ( P < 0.001). In stages 2 and 3, the pain intensity was significantly lower in group A ( P < 0.001). Upon discharge, the visual analog scale score improved in all groups; however, the Iowa Satisfaction with Anesthesia Scale score was significantly higher in group A ( P < 0.001). There was no difference in periprocedural complications between the two groups ( P = 0.743)., Conclusion: PVP causes significant procedural pain, and PVNB is a potentially effective modality for enhancing patient satisfaction and reducing procedural pain., Competing Interests: The authors declare no conflict of interest., (Copyright © 2023 Wolters Kluwer Health, Inc.

- Abstract
Deciding whether to include or exclude the papillary muscles and trabeculae to blood pool is essential, because quantifications of left ventricular (LV) functional parameters and myocardial mass are significantly affected. As a result, such inclusion or exclusion might produce different indices for diagnosis and therapy. Using cardiac computed tomography (CT), we obtained standard values of the portion of papillary muscle and trabeculae in normal adults, and to find out how the inclusion or exclusion of papillary muscle and trabeculae affect LV functional parameters depending on the patient group. Excluding the papillary muscles from the LV mass results in easier automated contour detection using CT. The percentage portions of papillary muscle and trabeculae to LV end-diastolic volume (EDV) and LV mass (LVM) were 11.9 ± 5.6% and 20.2 ± 4.3%, respectively, significantly affecting disease diagnosis. Imaging should be consistent at follow-up and include or exclude the papillary muscles and trabeculae to avoid introducing significant differences between measurements., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2023 the Author(s).

- Abstract
Background: Patients with primary malignant brain tumors (PMBTs) experience uncertainty in illness (UI) because of the high recurrence rate and symptoms that occur during treatment., Objective: To develop and test a model based on the Uncertainty in Illness Theory to predict the UI and cancer coping experienced by PMBT patients., Methods: This was a cross-sectional study using path analysis. The participants were adults diagnosed with PMBT who completed a questionnaire about demographic and disease-related characteristics, UI, cancer coping, brain tumor symptoms, and social support. Clinical data (eg, the diagnosis, tumor location, and grade) were obtained from electronic health records. Data were analyzed using SPSS 26.0 and the MVN , psych , and lavaan packages in R 4.1.0., Results: This study included 203 PMBT patients. The hypothesized model satisfied all statistical criteria (comparative fit index = 0.998, root mean square error of approximation = 0.044, standardized root mean square residual = 0.016). The indirect and direct associations of UI in the path from social support to cancer coping were all significant with a 95% bootstrapping confidence interval. Although the indirect and direct associations of UI in the path of brain tumor symptoms and cancer coping did not have direct or total effects, the indirect effect was statistically significant., Conclusions: Uncertainty in illness mediated brain tumor symptoms and social support to predict cancer coping., Implications for Practice: A nurse-led intervention for cancer coping among PMBT patients can be developed by considering symptoms and social support and UI as a mediator., Competing Interests: S.H. received a scholarship from Brain Korea 21 FOUR Project funded by National Research Foundation of Korea, Yonsei University College of Nursing.

- Abstract
Septic cavernous sinus thrombosis (CST) is a rare, life-threatening condition that commonly originates from sinusitis. Posterior nasal septal abscess (NSA) is an extremely rare cause of septic CST because it is a very rare condition by itself. Here we report a rare case involving an elderly woman with septic CST associated with a posterior NSA that was successfully treated without any sequelae. Incision and drainage of the posterior NSA were performed under local anesthesia, and the nasal packing was removed 2 days postoperatively. Pus from the abscess was sent for culture and sensitivity analyses, which revealed Enterococcus faecium . She was treated with intravenous (IV) third-generation cephalosporin (2 g twice daily) and IV vancomycin (0.75 g twice daily) for 4 weeks. IV low-molecular-weight heparin was administered at a dose of 40 mg twice daily for 4 days, followed by warfarin (3 mg once a day) for 21 days. The patient was discharged without any sequelae after 4 weeks. At the 2-month follow-up, she did not complain of any further symptoms. The findings from this case suggest that clinicians should maintain a high index of suspicion and provide prompt treatment to prevent mortality and morbidity associated with septic CST., Competing Interests: The authors report no conflicts of interest., (Copyright © 2023 by Mutaz B.

- Abstract
Many studies have reported electromagnetic navigation bronchoscopy (ENB) diagnostic yields and the importance of size and computed tomography (CT) bronchus sign. This study aimed to determine the diagnostic yield of ENB alone, using forceps biopsy and cytology. We analyzed the factors associated with yield and complications according to gross specimen size. This retrospective study included patients who underwent ENB using forceps for suspected lung lesions on CT between January 2020 and December 2022 in South Korea. Factors related to the ENB diagnostic yield and complications were evaluated, and the impacts of gross specimen size and cytology were analyzed. A total of 276 patients were analyzed. The final diagnostic yield was 75.5% after excluding indeterminate cases. Sensitivity and specificity were 74.2% and 100%, respectively. Pneumothorax developed in 1.4% (4/276) of cases, with no grade 3 or higher bleeding. Univariable analysis showed that the number of biopsies and the size of the gross specimen were related to the diagnosis. Multivariable analyses showed that a larger lesion size on CT was a significant factor for diagnosis. The gross size of the specimens was not significantly associated with epinephrine use. ENB had acceptable diagnostic yield and safety for diagnosing lung lesions with suspected malignancy. Obtaining more tissue through biopsy may not increase bleeding or pneumothorax complications. Identifying patients with lesion characteristics, including CT bronchus sign, would help increase ENB diagnostic yield., Competing Interests: The authors have no funding and conflicts of interest to disclose., (Copyright © 2023 the Author(s).

- Abstract
Objectives: In Asian populations, the correlation between sepsis outcomes and body mass is unclear. A multicenter, prospective, observational study conducted between September 2019 and December 2020 evaluated obesity's effects on sepsis outcomes in a national cohort., Setting: Nineteen tertiary referral hospitals or university-affiliated hospitals in South Korea., Patients: Adult patients with sepsis ( n = 6,424) were classified into obese ( n = 1,335) and nonobese groups ( n = 5,089)., Measurements and Results: Obese and nonobese patients were propensity score-matched in a ratio of 1:1. Inhospital mortality was the primary outcome. After propensity score matching, the nonobese group had higher hospital mortality than the obese group (25.3% vs 36.7%; p < 0.001). The obese group had a higher home discharge rate (70.3% vs 65.2%; p < 0.001) and lower median Clinical Frailty Scale (CFS) (4 vs 5; p = 0.007) at discharge than the nonobese group, whereas the proportion of frail patients at discharge (CFS ≥ 5) was significantly higher in the nonobese group (48.7% vs 54.7%; p = 0.011). Patients were divided into four groups according to the World Health Organization body mass index (BMI) classification and performed additional analyses. The adjusted odds ratio of hospital mortality and frailty at discharge for underweight, overweight, and obese patients relative to normal BMI was 1.25 ( p = 0.004), 0.58 ( p < 0.001), and 0.70 ( p = 0.047) and 1.53 ( p < 0.001), 0.80 ( p = 0.095), and 0.60 ( p = 0.022), respectively., Conclusions: Obesity is associated with higher hospital survival and functional outcomes at discharge in Asian patients with sepsis., Competing Interests: The authors have disclosed that they do not have any potential conflicts of interest., (Copyright © 2023 The Author(s).

- Abstract
Rationale: Pulmonary blastoma is an extremely rare and highly aggressive tumor. Only a few hundred cases of pulmonary blastoma have been reported. In other cases, a definitive diagnosis is often made through surgical resection. The use of preoperative histopathological sampling in diagnosing was of limited value because of the variety of pulmonary blastoma histology. And there was no literature that the first biopsy was attempted with medical thoracoscopy for diagnosis., Patient Concerns: A 65-year-old man presented to our hospital with pleural effusion and lung mass., Diagnoses: The patient was initially diagnosed with dedifferentiated chondrosarcoma by medical thoracoscopic biopsy but the final diagnosis was pulmonary blastoma through bilobectomy., Interventions: Medical thoracoscopy, and video-assisted thoracoscopic surgery (bilobectomy) followed by adjuvant chemotherapy., Outcomes: After surgical resection of the tumor, adjuvant chemotherapy has been performed 5 cycles at 3 weeks intervals, and there was no evidence of recurrence on follow-up computed tomography performed 4 months after surgery., Lessons: Medical thoracoscopy is useful for the diagnosis of indeterminate pleural effusion; however, caution is needed when confirming rare malignancies, such as pulmonary blastoma. Although surgical resection is the treatment of choice, appropriate adjuvant chemotherapy to improve the prognosis may be necessary if there is pleural metastasis., Competing Interests: The authors have no funding and conflicts of interest to disclose., (Copyright © 2022 the Author(s).

- Abstract
In South Korea, there are few studies to understand the current status of pulmonary rehabilitation in clinical practice and develop it. This study aimed to assess the current status and annual changes in the number and pattern of prescriptions for pulmonary rehabilitation before and after its insurance coverage. The trends of pulmonary rehabilitation before and after its insurance coverage commencement were evaluated using the data of 24,380 patients during the 3-year period from 2016 to 2018 that were archived by the National Health Information Database of the Health Insurance Review and Assessment Service in South Korea. The annual total number of patients who received pulmonary rehabilitation was stratified by the type of prescription, sex, age, type of insurance, medical institution, and region. In addition, the frequencies of pulmonary rehabilitation for various diagnoses were investigated using the major codes of the Korean Standard Classification of Disease. The patients who received pulmonary rehabilitation increased by approximately 2 times from 5936 in 2016 (before insurance coverage) to 10,474 in 2019. Before 2017, most patients underwent simple pulmonary rehabilitation coded as MM290. However, since the insurance coverage of rehabilitation exercise for pulmonary disease (MM440), the proportions of patients receiving them increased. Men underwent pulmonary rehabilitation more often than women, and >70% of the patients were aged >60 years. Most patients received pulmonary rehabilitation at tertiary hospitals in Seoul. In 2016, pulmonary rehabilitation was prescribed more frequently for cerebral infarction; after 2017, it was prescribed more frequently for lung cancer. This study summarized the current status and trends of pulmonary rehabilitation in South Korea before and after National Health Insurance Service coverage, which commenced on January 1, 2017. A significant increase in the number of pulmonary rehabilitations was confirmed after the insurance coverage., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2022 the Author(s).

- Abstract
This study estimates the effect of a new dispatcher-assisted basic life support training program on the survival outcomes of out-of-hospital cardiac arrest (OHCA). Before-and-after intervention trials were conducted in Seoul. Patients who suffered OHCA in a private place from January 2014 to December 2017 were included. The intervention group was 3 districts; the other 22 districts were regarded as the control group. The primary outcome was survival up to hospital discharge. The difference-in-difference (DID) was calculated to evaluate changes in the survival outcomes of the 2 groups over the period. A total of 10,127 OHCA patients were included in the final analysis. OHCA patients in the intervention group were less likely to receive bystander cardiopulmonary resuscitation (57.8% vs 61.1%; P = .02) and showed lower survival outcomes (5.7% vs 6.4% for survival up to hospital discharge; P = .34 and 2.8% vs 3.7% for good neurological recovery; P = .11), but this was not statistically significant. Compared to 2014, good neurological recovery in 2017 was significantly improved in the intervention group (DID for good neurological recovery = 3.2%; 0.6-5.8). There were no statistically significant differences in return of spontaneous circulation and survival up to hospital discharge between the 2 groups (DID for survival to discharge was 1.8% [-1.7 to 5.3] and DID for return of spontaneous circulation was -2.5% [-9.8 to 4.8]). Improvement in neurological recovery was observed in the 3 districts after implementing the new dispatcher-assisted basic life support training program., Competing Interests: The authors have no funding and conflicts of interest to disclose., (Copyright © 2022 the Author(s).

- Abstract
Many studies have suggested the possibility of using functional near-infrared spectroscopy (fNIRS) devices as neuroimaging tools in various patients. We aimed to evaluate whether fNIRS to measure the prefrontal cortex (PFC fNIRS) is suitable as a screening tool for cognitive impairments. Sixty participants, divided into normal, mild cognitive impairment, and dementia groups, were instructed to wear an fNIRS device during cognitive assessments to assess whether there is a significant difference in the PFC activity between the groups. A significant difference in PFC activity between the groups was observed during the verbal fluency test. Moreover, the PFC activity during the verbal fluency test significantly correlated with the existing cognitive screening tool score. These results suggested that PFC fNIRS can be used as a cognitive impairment screening tool for mild cognitive impairment and dementia. A larger sample size is needed to validate the potential of PFC fNIRS as a cognitive impairment screening tool., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2021 Wolters Kluwer Health, Inc.

- Abstract
Objective: The aim of the study was to investigate the diagnostic feasibility of radiomics analysis using magnetic resonance elastography (MRE) to assess hepatic fibrosis in patients with nonalcoholic fatty liver disease (NAFLD)., Methods: One hundred patients with suspected NAFLD were retrospectively enrolled. All patients underwent a liver parenchymal biopsy. Magnetic resonance elastography was performed using a 3.0-T scanner. After multislice segmentation of MRE images, 834 radiomic features were analyzed using a commercial program. Radiologic features, such as median and mean values of the regions of interest and variable clinical features, were analyzed. A random forest regressor was used to extract important radiomic, radiological, and clinical features. A random forest classifier model was trained to use these features to classify the fibrosis stage. The area under the receiver operating characteristic curve was evaluated using a classifier for fibrosis stage diagnosis., Results: The pathological hepatic fibrosis stage was classified as low-grade fibrosis (stages F0-F1, n = 82) or clinically significant fibrosis (stages F2-F4, n = 18). Eight important features were extracted from radiomics analysis, with the 2 most important being wavelet-high high low gray level dependence matrix dependence nonuniformity-normalized and wavelet-high high low gray level dependence matrix dependence entropy. The median value of the multiple small regions of interest was identified as the most important radiologic feature. Platelet count has been identified as an important clinical feature. The area under the receiver operating characteristic curve of the classifier using radiomics was comparable with that of radiologic measures (0.97 ± 0.07 and 0.96 ± 0.06, respectively)., Conclusions: Magnetic resonance elastography radiomics analysis provides diagnostic performance comparable with conventional MRE analysis for the assessment of clinically significant hepatic fibrosis in patients with NAFLD., Competing Interests: The authors declare no conflict of interest., (Copyright © 2022 Wolters Kluwer Health, Inc.

- Abstract
Background: Frail patients with atrial fibrillation (AF) are less likely to receive anticoagulation than nonfrail patients with AF despite frailty being associated with poorer clinical outcomes including stroke. Using a population-based cohort, we sought to assess the effectiveness and safety of oral anticoagulants (OACs) in frail patients with AF., Methods: This retrospective cohort study analyzed 83 635 patients aged at least 65 years with AF and frailty (≥5 Hospital Frailty Risk Score) between January 1, 2013 and December 31, 2016 from the Korean National Health Insurance Service database. To account for the differences between patients receiving OAC or not and across different OAC regimens, propensity score-weighting was used. Net adverse clinical event, defined as the first event of ischemic stroke, major bleeding, or cardiovascular death, was compared. In addition, each individual outcome was examined separately., Results: In the study population (57.1% women; mean age, 78.5±7.2 years), a total of 14 968 net adverse clinical event, 3718 ischemic stroke, 5536 major bleeding, and 6188 cardiovascular death occurred. In comparison with no OAC use, OAC use was associated with lower risks of net adverse clinical event (hazard ratio, 0.78 [95% CI, 0.75-0.82]), ischemic stroke (hazard ratio, 0.91 [95% CI, 0.86-0.97]), and cardiovascular death (hazard ratio, 0.52 [95% CI, 0.49-0.55]), but no difference was observed for major bleeding (hazard ratio, 1.02 [95% CI, 0.95-1.10]). Compared with warfarin, all four individual direct OAC were associated with decreased risks of net adverse clinical event, ischemic stroke, major bleeding, and cardiovascular death. The associations for OAC use (compared to no OAC use) or direct OAC use (compared to warfarin) with favorable outcomes were more prominent in individuals with a higher CHA
2 DS2 -VASc score of at least 3., Conclusions: Among frail patients with AF, OAC treatment was associated with a positive net clinical outcome. Direct OACs provided lower incidences of stroke, bleeding, and mortality, compared with warfarin.- Published

- Abstract
Objectives: To investigate whether administration of a vasopressor within 1 hour of first fluid loading affected mortality and organ dysfunction in septic shock patients., Design: Prospective, multicenter, observational study., Setting: Sixteen tertiary or university hospitals in the Republic of Korea., Patients: Patients with septic shock (n = 415) were classified into early and late groups according to whether the vasopressor was initiated within 1 hour of the first resuscitative fluid load. Early (n = 149) patients were 1:1 propensity matched to late (n = 149) patients., Interventions: None., Measurement and Main Results: The median time from the initial fluid bolus to vasopressor was shorter in the early group (0.3 vs 2.3 hr). There was no significant difference in the fluid bolus volume within 6 hours (33.2 vs 35.9 mL/kg) between the groups. The Sequential Organ Failure Assessment score and lactate level on day 3 in the ICU were significantly higher in the early group than that in the late group (Sequential Organ Failure Assessment, 9.2 vs 7.7; lactate level, 2.8 vs 1.7 mmol/L). In multivariate Cox regression analyses, early vasopressor use was associated with a significant increase in the risk of 28-day mortality (hazard ratio, 1.83; 95% CI, 1.26-2.65)., Conclusions: Vasopressor initiation within 1 hour of fluid loading was associated with higher 28-day mortality in patients with septic shock., Competing Interests: Dr. Lim received support for article research from the 2019 Research Grant (2019E280500) from the Korean Disease Control and Prevention Agency.

- Abstract
Rationale: Spontaneous retroperitoneal hematomas due to anticoagulant therapy rarely occur. Retroperitoneal hematomas can cause severe pain in the groin, quadriceps femoris muscle weakness, hemodynamic instability, and abdominal distension. They rarely cause compressive neuropathy of the femoral nerve transversing the iliacus muscle. Differential diagnosis is not easy because they have similar clinical features to retroperitoneal hematomas., Patient Concerns: A 72-year-old female patient whose right arm was stuck in a bookshelf for 5 days developed right cephalic vein thrombosis. After 5 days of intravenous heparin therapy for venous thrombosis, she presented with sudden right groin pain, right leg paresis, hemodynamic instability, and abdominal distension., Diagnosis: Emergency abdominal and pelvic CT showed a large number of hematomas in the bilateral retroperitoneal space with active bleeding of the right lumbar artery. An electrodiagnostic study was performed 2 weeks later to check for neuromuscular damage in the right lower extremity, and right compressive femoral neuropathy was confirmed., Interventions: Heparin therapy was discontinued; emergency embolization of the lumbar artery was performed. After 2 weeks, the patient started receiving physical, occupational, and transcutaneous electrical stimulation therapies., Outcomes: She became hemodynamically stable after arterial embolization; a significant decrease in hematoma and patency of the femoral nerve was confirmed on follow-up pelvic MRI. After 2 months of comprehensive rehabilitation, the muscle strength of the right leg significantly improved, and the pain disappeared., Lessons: Although rare, spontaneous retroperitoneal hematomas may occur in patients receiving anticoagulant medications. They may even occur in patients receiving emergency anticoagulant therapy. Compressive femoral neuropathy due to retroperitoneal hematomas should be considered if muscle weakness and groin pain are observed. Early diagnosis and appropriate treatment plan of compressive femoral neuropathy due to retroperitoneal hematoma are helpful for a good prognosis., Competing Interests: The authors report no conflicts of interest., (Copyright © 2022 the Author(s).

- Abstract
Abstract: Early or multiple recurrences of symptomatic common bile duct (CBD) stones are troublesome late complications after endoscopic stone removal. We aimed to determine the factors related to early or multiple recurrences of CBD stones.We retrospectively analyzed patients who underwent endoscopic CBD stone extraction in a single institute between January 2006 and December 2015. Patients were divided into 2 groups according to the number and interval of CBD stone recurrences: single versus multiple (≥2) and early (<1.5 years) versus late (≥1.5 years) recurrence.After exclusion, 78 patients were enrolled and followed up for a median of 1974 (IQR: 938-3239) days. Twenty-seven (34.6%) patients experienced multiple recurrences (≥2 times), and 26 (33.3%) patients experienced early first recurrence (<1.5 years). In the multivariate analysis, CBD angulation was independently related to multiple CBD stone recurrence (OR: 4.689, P = .016), and endoscopic papillary large balloon dilation was independently related to late first CBD stone recurrence (OR: 3.783, P = .025). The mean CBD angles were more angulated with increasing instances of recurrence (0, 1, 2, 3, and ≥4 times) with corresponding values of 150.3°, 148.2°, 143.6°, 142.2°, and 126.7°, respectively (P = .011). The period between the initial treatment and first recurrence was significantly longer than the period between the first and second recurrence (P = .048).In conclusion, greater CBD angulation is associated with the increased number of CBD stone recurrence, and EPLBD delays the recurrence of CBD stones after endoscopic CBD stone removal., Competing Interests: The authors have no conflict of interest to declare., (Copyright © 2022 the Author(s).

- Abstract
Background/aims: To assess the efficacy and safety of intra-articular sacroiliac glucocorticoid injection in ankylosing spondylitis (AS)., Methods: Patients with AS undergoing fluoroscopy-guided intra-articular sacroiliac glucocorticoid injection were enrolled between 2012 and 2018. Efficacy was assessed by numeric pain rating scale, acute phase reactants, Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), Bath Ankylosing Spondylitis Functional Index, and Ankylosing Spondylitis Disease Activity Score (ASDAS). Patients who started biologics within 3 months despite the intervention were compared with those not starting biologics, hence: the nonbiologic group., Results: A total of 96 patients were treated, with a total of 107 injections. After intervention, there were significant decreases in numeric pain rating scale (7.8 ± 1.8 vs. 3.3 ± 2.2, p < 0.001) and acute phase reactants level (erythrocyte sedimentation rate [ESR] 23.0 mm/h [10.0-47.0 mm/h] vs. 13.0 mm/h [4.0-27.0 mm/h], p < 0.001; C-reactive protein [CRP] 1.0 mg/dL [0.2-2.7 mg/dL] vs. 0.2 mg/dL [0.2-0.9 mg/dL], p < 0.001). Disease activity scores also decreased for BASDAI (6.2 ± 1.8 vs. 4.5 ± 2.5, p = 0.001), Bath Ankylosing Spondylitis Functional Index (5.5 [4.1-7.0] vs. 1.8 [0.5-4.1], p = 0.001), ASDAS-CRP (2.9 ± 1.0 vs. 2.3 ± 1.3, p = 0.046), and ASDAS-ESR (3.7 ± 1.1 vs. 2.4 ± 1.3, p < 0.001). However, 12 patients (12.5%) started biologics within 3 months. These patients showed higher ESR (91.0 mm/h [IQR 21.0-113.0 mm/h] vs. 21.5 mm/h [IQR 9.5-43.0 mm/h], p = 0.010), CRP (8.0 mg/dL [IQR 1.11-17.1 mg/dL] vs. 0.8 mg/dL [IQR 0.2-1.8 mg/dL], p = 0.002), BASDAI (7.4 ± 1.2 vs. 5.9 ± 1.8, p = 0.027), and ASDAS-CRP (4.0 ± 0.5 vs. 2.8 ± 1.0, p = 0.004) than the nonbiologic group. There was no serious adverse event., Conclusions: Intra-articular sacroiliac glucocorticoid injection can be a safe and effective treatment option for active sacroiliitis in AS., Competing Interests: The authors declare no conflict of interest., (Copyright © 2020 Wolters Kluwer Health, Inc.

- Abstract
Rationale: Complex regional pain syndrome (CRPS) is a painful condition classified as type I or II depending on the absence or presence of nerve injury, respectively. Injury to the lateral dorsal cutaneous nerve (LDCN), a branch of the sural nerve, is a rare occurrence observed after a sprain or procedures conducted on the lateral side of the ankle., Patient Concerns: A 38-year-old female, who had undergone prolotherapy for a sprain in the lateral side of the left ankle 3 months ago, presented with persistent causalgia and dysesthesia around the injection site., Diagnosis: An electrodiagnostic study was conducted, which confirmed that the patient had peripheral neuropathy of the left LDCN. Considering the digital infrared thermal imaging and three-phase bone scan findings and the clinical presentation, the condition was diagnosed as CRPS type II due to iatrogenic LDCN injury according to the Budapest diagnostic criteria for CRPS., Interventions: The patient was treated with steroid pulse therapy, physical therapy, and transcutaneous electrical nerve stimulation, as well as nonsteroidal anti-inflammatory drugs, pregabalin, and tricyclic antidepressants., Outcomes: After 1 month of treatment, allodynia of the left foot persisted, but the pain reduced from 6 points to 3 points on the numeric rating scale. Partial recovery of amplitude and conduction velocity was confirmed in the follow-up electrodiagnostic study., Lessons: LDCN injury should be considered in patients who complain of persistent lateral ankle and foot paresthesia or pain after sprain or procedures performed on the lateral side of the ankle. Early diagnosis and treatment can lead to a good prognosis when the LDCN injury has progressed to CRPS., Competing Interests: The authors have no funding and conflicts of interest to disclose., (Copyright © 2021 the Author(s).

Abstract: Various types of flaps are widely utilized as reconstructive options for patients with soft tissue defects. However, the postoperative monitoring of the flap requires a large amount of time and effort. The aim of this study was to evaluate the efficacy and safety of this novel monitoring procedure using negative pressure wound therapy (NPWT) immediately after the flap operations.A retrospective analysis was performed on patients who underwent free flaps and perforator flaps from March 2019 to December 2020. The flaps were managed by either novel NPWT method or conventional dressing. Among NPWT group, computed tomography angiography was performed in randomly selected 5 flaps on the third postoperative day for evaluation of pedicle compression. Statistical analysis was performed between the 2 groups.A total of 54 flaps were included in this study. Twenty seven flaps were managed using novel NPWT method and 27 flaps were managed using conventional dressing. There was no statistically significant difference in flap survival rates between the 2 groups (P = .91). The patency of flap pedicles in the NPWT group was confirmed by comparing the computed tomography angiography findings. The estimated total flap monitoring time and cost for 5 days was significantly decreased by the application of the novel NPWT monitoring system.Through the application of the novel postoperative monitoring system using NPWT, there is efficient evaluation of the flap. Furthermore, safe flap monitoring is possible with the reduced risk of infection by the avoidance of multiple manual dressing performed in the conventional method., Competing Interests: The authors have no funding and conflicts of interest to disclose., (Copyright © 2021 the Author(s).

Abstract: Nasal tip plasty is a surgery that determines important rhinoplasty outcomes. A variety of autologous and alloplastic implants are utilized in this procedure, including 1 synthetic material known as polycaprolactone (PCL). This study provides background on the ready-made three-dimensional printed PCL implant for nasal lobule correction, before discussing the usefulness and effectiveness of the implant. A total of 23 patients who visited our hospital between January 2018 and January 2020 were evaluated in this study. We used 3 types of PCL implant to get an ideal shape for the nasal tip: tipball (globular shape), droneball (rugby ball shape), and dumbbell (dumbbell shape). The authors compared nasolabial angle and tip projection at the preoperative and postoperative period via photographic anthropometric analysis. In 4 patients, we also examined the dead space between the implant and soft tissue via ultrasonography. The follow-up period averaged 9.5 months and no serious complications were found after surgery. The nasolabial angle and tip projection had an average postoperative increase of 6.4° and 0.044, respectively. Ultrasonography revealed the attachment of the implant at the insertion site and no dead space was found. This is the first attempt to apply a ready-made three-dimensional printed PCL implant to a nasal lobule correction procedure. As the implant was easy to use and showed good results, it may be useful for aesthetic purposes in future nasal tip plasty procedures., Competing Interests: The authors report no conflicts of interest., (Copyright © 2021 by Mutaz B.

- Abstract
Abstract: Polymyxin B hemoperfusion (PMX-HP) may improve the clinical outcomes of patients with sepsis and gram-negative bacteremia by reducing endotoxin levels. However, the recent studies with the variable degree of renal support have shown that the improvement of survival rate by PMX-HP remains unclear in such patients. Therefore, we investigated whether the addition of PMX-HP to continuous renal replacement therapy (CRRT) could improve the survival rate than CRRT alone. This study included 231 patients with sepsis undergoing CRRT alone or PMX-HP with CRRT. Primary outcomes were 28-day and 90-day all-cause mortality. Urine output, ventilator support, and Sequential Organ Failure Assessment (SOFA) score were not significantly different between the two groups. Crude 28-day and 90-day mortality rates were higher in the PMX-HP with CRRT group than in the CRRT-alone group. To correct for disease severity, propensity score (PS) matching was performed with acute respiratory distress syndrome, mechanical ventilation support, extracorporeal membrane oxygenation, infection source (abdomen), age, inotropic score, SOFA score, C-reactive protein, and procalcitonin levels. Sixty-six PS-matched pairs revealed significantly higher 28-day and 90-day mortality rates in the PMX-HP with CRRT group than in the CRRT-alone group. Considering the mortality rates after PS matching, the additional use of PMX-HP does not improve the clinical outcomes of patients with sepsis and acute kidney injury requiring CRRT., Competing Interests: The authors report no conflicts of interest., (Copyright © 2021 by the Shock Society.)

- Abstract
Study Design: A retrospective cohort study., Objective: The aim of this study was to develop recurrence-prediction models of pyogenic vertebral osteomyelitis (PVO)., Summary of Background Data: Prediction of recurrence in PVO is crucial to avoid additional prolonged antibiotic therapy and aggressive spinal surgery and to reduce mortality. However, prediction of PVO recurrence by previously identified, initial risk factors is limited in PVO patients who exceptionally require prolonged antibiotic therapy and experience various clinical events during the treatment. We hypothesized that time-series analysis of sequential C-reactive protein (CRP) routinely measured to estimate the response to the antibiotics in PVO patients could reflect such long treatment process and increase the power of the recurrence-prediction model., Methods: A retrospective study was performed to develop a PVO recurrence-prediction model, including initial risk factors and time-series data of CRP. Of 704 PVO patients, 493 and 211 were divided into training and test cohorts, respectively. Conventional stepwise logistic regression and artificial neural network (ANN) models were created from the training cohort, and the predictions of recurrence in the test cohort were compared., Results: Prediction models using initial risk factors showed poor sensitivity (4.7%) in both conventional logistic model and ANN models. However, baseline ANN models using time-series CRP data showed remarkably increased sensitivity (55.8%-60.5%). Ensemble ANN model using both initial risk factors and time-series CRP data showed additional benefit in prediction power., Conclusion: The recurrence-prediction models for PVO created only using the initial risk factors showed low sensitivity, regardless of statistical method. However, ANN models using time-series data of CRP values and their ensemble model showed considerably increased prediction power. Therefore, clinicians treating PVO patients should pay attention to the treatment response including changes of CRP levels to identify high-risk patients for recurrence, and further studies to develop recurrence-prediction model for PVO should focus on the treatment response rather than initial risk factors.Level of Evidence: 4., (Copyright © 2021 Wolters Kluwer Health, Inc.

- Abstract
Purpose of Review: Uterine sarcomas are rare and are often challenging to differentiate on imaging from benign mimics, such as leiomyoma. As functional MRI techniques have improved and new adjuncts, such as machine learning and texture analysis, are now being investigated, it is helpful to be aware of the current literature on imaging features that may sometimes allow for preoperative distinction., Recent Findings: MRI, with both conventional and functional imaging, is the modality of choice for evaluating uterine mesenchymal tumors, especially in differentiating uterine leiomyosarcoma from leiomyoma through validated diagnostic algorithms. MRI is sometimes helpful in differentiating high-grade stromal sarcoma from low-grade stromal sarcoma or differentiating endometrial stromal sarcoma from endometrial carcinoma. However, imaging remains nonspecific for evaluating rarer neoplasms, such as uterine tumor resembling ovarian sex cord tumor or perivascular epithelioid cell tumor, primarily because of the small number and power of relevant studies., Summary: Through advances in MRI techniques and novel investigational imaging adjuncts, such as machine learning and texture analysis, imaging differentiation of malignant from benign uterine mesenchymal tumors has improved and could help reduce morbidity relating to misdiagnosis or diagnostic delays., (Copyright © 2021 Wolters Kluwer Health, Inc.

- Abstract
Abstract: Cholesterol granuloma is commonly found in the mastoid air cells but is rare in the paranasal sinuses. The most commonly affected sinuses are the frontal sinus, followed by the maxillary sinus. Cholesterol granuloma can be difficult to diagnose because clinical manifestations and radiologic findings are similar to those of other sinonasal disorders. The authors observed 4 cases of cholesterol granuloma that were preoperatively suspected to be nasal polyps or mucoceles. Here, the authors report on their clinical presentation and their successful treatment using the endoscopic sinus approach. These cases expand the current literature on cholesterol granuloma in the paranasal sinuses., Competing Interests: The authors report no conflicts of interest., (Copyright © 2021 by Mutaz B.

- Abstract
Background: The middle phalangeal type of postaxial polysyndactyly (MPPP) of the foot is a common congenital limb anomaly and is usually treated surgically at a young age. Owing to the insufficiency of radiologic evaluation due to largely cartilaginous portions of the pediatric foot, we performed intraoperative arthrography (IOA) for MPPP. This study was aimed at presenting a new classification system for foot MPPP in young children based on IOA findings and investigating its intraoperative decision-making., Methods: Thirty-seven patients aged below 2 years who underwent IOA and surgical treatment of foot MPPP in our institute between January 2018 and April 2020 were retrospectively reviewed. The mean patient age at operation was 1.31 years (range, 0.91 to 1.99 y). IOA was performed in the common proximal interphalangeal (PIP) joint. The excisional level and side were determined on the basis of the IOA findings and bony alignment between the proximal and distal phalanges for functional and cosmetic purposes. Arthrographic findings and surgical procedures were recorded., Results: A new classification divided MPPP into 2 major types according to the presence (type A) or absence (type B) of longitudinal contrast filling between the fifth and sixth middle phalanges. These 2 major types were further divided into 4 subtypes according to the shape of the PIP joint by contrast filling. There were 19, 15, and 3 cases of type A, B, and indeterminate IOA. Fifth and sixth ray excisions were performed in 26 and 11 cases, respectively. Interobserver reliability of the classification represented excellent agreement (Cohen κ coefficient=0.823)., Conclusions: Our new classification based on IOA helped determine the articular dominance and its detailed morphology, which can help predict postoperative stability and mobility of the remaining toe. IOA is a simple, safe, and useful imaging tool for the surgical treatment of foot MPPP in patients aged below 2 years., Level of Evidence: Level III., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2021 Wolters Kluwer Health, Inc.

- Abstract
Background: Previous studies have shown conflicting results on the benefits of deferred stenting (DS) in infarct size and the incidence of microvascular obstruction in patients with ST elevation myocardial infarction (STEMI). However, effect of DS on left ventricular (LV) function was not known. We aimed to evaluate whether DS improve LV function and relevant clinical outcomes after STEMI, using follow-up data from the INNOVATION study (NCT02324348)., Methods: In total, 114 patients were randomly assigned to DS group or immediate stenting (IS) group at a 1:1 ratio. LV functional remodeling indices and MACE (major adverse cardiac events: a composite of death, non-fatal MI, unplanned target vessel revascularization, or hospitalization due to heart failure) were compared between DS and IS groups., Results: Serial echocardiographic analyses were completed in 89 subjects (78%). There were no significant changes in LV volume in either group. While LV ejection fraction and wall motion score index (WMSI) improved in both groups during follow-up, the increments were not statistically different between the 2 groups (4.3 ± 8.2 vs 3.2 ± 7.1, P = .504 for ΔLV ejection fraction; -0.16 ± 0.25 vs -0.16 ± 0.25, P = .99 for ΔWMSI). However, E/e'' was decreased and e' was increased only in the DS group (-3.31 ± 5.60 vs -0.46 ± 3.10, P = .005 for ΔE/e'; 0.77 ± 1.71 vs -0.22 ± 1.64, P = .009 for Δe'). The incidence of major adverse cardiac events was numerically lower in the DS group than in the IS group without a statistical significance at 1-year follow-up., Conclusions: Routine DS improved LV diastolic function but not systolic function compared with IS in patients with STEMI., (Copyright © 2021 the Author(s).

- Abstract
Objective: To investigate the effects of single sensory impairment (SSI; visual or auditory) or dual sensory impairment (DSI; visual and auditory) on dementia and longitudinal changes of neuropsychological test scores., Methods: In this nationwide, prospective, community-based elderly cohort study, KLOSCAD (the Korean Longitudinal Study on Cognitive Aging and Dementia), 6,520 elderly individuals (58-101 years) representing the general population were included. We defined visual and auditory sensory impairment via self-report questionnaire: 932 had normal sensory function, 2,957 had an SSI, and 2,631 had a DSI. Demographic and clinical variables including cognitive outcomes were evaluated every 2 years over 6 years. Through logistic regression, Cox regression, and linear mixed model analysis, the relationship between SSI or DSI and dementia prevalence, dementia incidence, and change in neuropsychological scores were evaluated., Results: At baseline, DSI was significantly associated with increased dementia prevalence compared to normal sensory function (odds ratio [OR] 2.17, 95% confidence interval [CI] 1.17-4.02), but SSI was not (OR 1.27, 95% CI 0.66-2.41). During the 6-year follow-up, the incidence of dementia was significantly higher in the DSI group than in the normal sensory function group (hazard ratio 1.9, 95% CI 1.04-3.46) and neuropsychological scores significantly decreased (β -0.87, 95% CI [-1.17 to -0.58])., Conclusions: Our results suggest that coexisting visual and hearing impairments facilitate dementia prevalence, dementia incidence, and cognitive decline, but visual or hearing impairment alone do not. Visual and hearing impairment may lead to dementia or cognitive decline independent of Alzheimer pathology., (© 2021 American Academy of Neurology.)

- Abstract
Abstract: High-intensity focused ultrasound (HIFU) is effective for the ablation of uterine fibroids. However, no research has indicated whether HIFU ablation of uterine fibroids might be improved by application of contrast-enhanced ultrasonography (CEUS) with Sonazoid as a contrast agent. This study aimed to assess the clinical significance of Sonazoid-based CEUS 30 minute before HIFU ablation of uterine fibroids.This retrospective cohort study included Asian patients with solitary uterine fibroids who were treated with HIFU at Seoul HICARE Clinic (South Korea; n = 34) and the Second Affiliated Hospital of Chongqing Medical University (China; n = 30) between August 1, 2017, and October 31, 2017. The patients in Seoul underwent Sonazoid-based CEUS 30 minute before HIFU. All the patients received contrast-enhanced magnetic resonance imaging to diagnose uterine fibroids. The ablation results were evaluated 1 day after HIFU by contrast-enhanced magnetic resonance imaging or Sonazoid-based CEUS.All the patients were successfully treated with HIFU. The CEUS+HIFU group had lower values for sonication power, treatment time, sonication time, total energy applied, and energy efficiency factor compared with HIFU alone group (P < .001). There were no major adverse events after ablation therapy in either group. The incidence of post-procedure sacrococcygeal pain was lower in the CEUS+HIFU group than that in the HIFU alone group (P = .045), while the incidences of all other intraoperative and postoperative adverse events were similar between the 2 groups.Our findings suggest that Sonazoid-based CEUS before HIFU may enhance the ablation of uterine fibroids., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2021 the Author(s).

- Abstract
Background: Low back pain is a very common disease. Many patients with chronic low back pain (CLBP) have been treated by complementary and alternative medicine such as acupuncture (AT) treatment. A type of AT, thread embedding acupuncture (TEA), consists of a thread that can continually stimulate at the AT points and has mechanical and chemical effects. Although TEA was widely used in clinical practice, there was little evidence of its efficacy and safety for CLBP., Methods: This clinical trial was randomized, controlled, assessor-blinded, two-armed, parallel, and conducted in multiple centers. Four Korean medical institutions recruited 38 outpatients with CLBP. The participants were randomly allocated to a treatment group (TEA combined with AT) or a control group (only AT) in a 1:1 ratio. All participants received conventional AT twice a week for 8 weeks (16 sessions) at 15 AT points (GV3 and bilateral BL23, BL24, BL25, BL26, BL40, BL60, and EX-B5) and the treatment group participants additionally received TEA once a week for 8 weeks (8 sessions) on 10 AT points in the multifidus, spinal erector, and lumbar quadrate muscles. The primary outcome measure of this study was the change of visual analog scale (VAS) from baseline (0 week) to the end of intervention (8 weeks). Secondary outcome measures included clinically relevant improvement (minimal clinically important difference) and 3% to 50% decrease on VAS, disability level (Korean version of Roland and Morris disability questionnaire), quality of life (Korean version of European quality of life 5dimension), global assessment (patient global impression of change), economic analysis, credibility test, and safety assessment., Results: The treatment group showed a significant reduction in VAS scores when compared with the control group (-33.7 ± 25.1 vs -15.6 ± 17.0, P = .013). As for the secondary outcome measures, the treatment group showed significant difference in 50% decrease on VAS and patient global impression of change. There was no serious adverse event associated with TEA and AT., Conclusion: This clinical trial documents the efficacy and safety of TEA combined with AT for the management of CLBP.

- Abstract
Introduction: A new dispatcher-assisted basic life support training program, called "Home Education and Resuscitation Outcome Study (HEROS)" was developed with a goal to provide high-quality dispatcher-assisted cardiopulmonary resuscitation (CPR) training, with a focus on untrained home bystanders. This study aimed to determine whether the HEROS program is associated with improved quality in CPR performance during training and willingness to provide bystander CPR compared with other basic life support programs without dispatcher-assisted CPR (non-HEROS)., Methods: This clustered randomized trial was conducted in 3 district health centers in Seoul. Intervention group was trained with the HEROS program and control group was trained with non-HEROS program. The primary outcome was overall CPR quality, measured as total CPR score. Secondary outcomes were other CPR quality parameters including average compression depth and rate, percentages of adequate depth, and acceptable release. Tertiary outcomes were posttraining survey results. Difference in difference analysis was performed to analyze the outcomes., Results: Among total 1929 trainees, 907 (47.0%) were trained with HEROS program. Compared with the non-HEROS group, the HEROS group showed higher-quality CPR performances and better maintenance of their CPR quality throughout the course (total scores of 84% vs. 80% for first session and 72% vs. 67% for last session; difference in difference of 12.2 vs. 13.2). Other individual CPR parameters also showed significantly higher quality in the HEROS group. The posttraining survey showed that both groups were highly willing to perform bystander CPR (91.4% in the HEROS vs. 92.3% in the non-HEROS) with only 3.4% of respondents in the HEROS group were not willing to volunteer compared with 6.2% in the non-HEROS group (P < 0.01)., Conclusions: The HEROS training program helped trainees perform high-quality CPR throughout the course and enhanced their willingness to provide bystander CPR.
