Study Design: A retrospective study. Objective: To investigate the effects of percutaneous transforaminal endoscopic decompression (PTED) for lumbar stenosis associated with adult degenerative scoliosis and to analyze the correlation between preoperative radiological parameters and postoperative surgical outcomes. Methods: Two years of retrospective data was collected from 46 patients with lumbar stenosis associated with adult degenerative scoliosis who underwent PTED. The visual analog scale (VAS), Oswestry Disability Index, and modified MacNab criteria were used to evaluate the clinical outcomes. Multiple linear regression analysis was used to analyze the correlation between radiological parameters and surgical outcomes. Results: The mean age of the 33 female and 13 male patients was 73.5 ± 8.1 years. The mean follow-up was 27.6 ± 3.5 months (range from 24 to 36). The average coronal Cobb angle was 24.5 ± 8.2°. There were better outcomes of the VAS for leg pain and Oswestry Disability Index after surgery. Based on the MacNab criteria, excellent or good outcomes were noted in 84.78% of patients. Multiple linear regression analysis showed that Cobb angle and lateral olisthy may be the predictors for low back pain. Conclusion: Transforaminal endoscopic surgery may be an effective and safe method for geriatric patients with lumbar stenosis associated with degenerative scoliosis. The predictive factors of clinical outcomes were severe Cobb angle and high degree lateral subluxation. Transforaminal endoscopic surgery may not be recommended for patients with Cobb angle larger than 30° combined with lateral subluxation.

Objective:The aims of this study were to determine the dominant affective temperament changes in stroke survivors and whether temperament affects the disability.Methods:A total of 63 stroke patients were included in this study. Temperament Evaluation of Memphis, Pisa, Paris and San Diego Autoquestionnaire was used to determine the dominant affective temperament (depressive, hyperthymic, cyclothymic, irritable or anxious). The disability level was measured with the Barthel index (BI).Results:Depressive temperament (17.5%) and anxious temperament (12.7%) were the most common dominant affective temperaments. The frequencies of irritable, cyclothymic and hyperthymic temperaments were 4.8, 3.2 and 0%, respectively. The mean BI score was 78.1 ± 18.3 in patients with depressive temperament and 67.4 ± 28.4 in patients without depressive temperament (p = 0.403). The mean BI score was 78.1 ± 15.3 in patients with anxious temperament and 68.0 ± 28.3 in patients without anxious temperament (p = 0.541). Multiple linear regression analysis indicated that BI score was not associated with affective temperament changes.Conclusion:The results of the current study suggest that depressive and anxious temperaments are the most common affective temperaments and that there appears to be no association between disability level and dominant affective temperament in stroke survivors.

Background: The state of Ohio implemented legislation in August of 2017 limiting the quantity of opioids a provider could prescribe. The purpose of this study was to identify if implementation of legislation affected opioid and nonopioid utilization in patients operatively treated for ankle fractures in the initial 90-day postoperative period after controlling for injury severity and preoperative narcotic usage. Methods: A retrospective review of 144 patients treated for isolated ankle fractures in a pre-law group (January 2017–July 2017; n = 73) and post-law group (January 2018–July 2018; n = 71) was completed using electronic medical records and a legal prescriber database. Total number of opioid prescriptions, pills, milligrams of morphine equivalents (MMEs), and nonopioid prescriptions were recorded. Multiple regression analysis was run to identify predictors of opioid prescribing after controlling for law group, demographic, preoperative narcotic use, and injury severity characteristics. Results: Mean MME prescribed per patient significantly decreased from 817.2 MME pre-law to 380.9 post-law ( P < .01). Mean number of opioid pills prescribed per patient decreased from 99.1 in the pre-law group and 55.3 in the post law group ( P < .001), respectively. Multiple linear regression analysis to predict the mean number of opioid pills prescribed was statistically significant ( R 2 = 0.33; P < .001), with law group adding significantly to the prediction ( P < .001). The multiple linear regression analysis to predict MME per patient was found to be statistically significant ( R 2 = 0.31; P < .001), with the law group contributing significantly ( P < .001). Conclusion: The Ohio prescriber law successfully contributed to the decreased number of opioid pills and MME prescribed in the initial 90-day postoperative period after controlling for injury severity and preoperative narcotic usage. Policies on opioid prescriptions may serve as an important public health tool in the fight against the opioid epidemic. Level of Evidence: Level III, retrospective comparative series.

Abstract Background The minimally invasive treatment for adult degenerative scoliosis has become more and more popular. The purpose of this study was to evaluate the efficiency of stand-alone oblique lateral interbody fusion for the treatment of adult degenerative scoliosis in terms of clinical and radiological outcomes. Methods A total of 18 patients with ADS who underwent stand-alone OLIF in our hospital from July 2017 to May 2018 were enrolled in the study. Clinical evaluations were performed with visual analogue scale (VAS) and Oswestry Disability Index (ODI). Radiographic outcomes were recorded in terms of coronal Cobb angle and lumbar lordosis. Results Mean patient age was 62.4 years, 50% of patients were female. Average follow up was 18.4 months. The average operative duration was 87.4 minutes, whilst the mean estimated blood loss was 45.6 ml. Mean coronal Cobb angle corrected from preoperative 15.2° to the final follow-up 6.8° (p < 0.05); and mean lumbar lordosis improved from preoperative 30.0° to 39.4° (p < 0.05). Mean disc height increased from preoperative 0.7 cm to 1.1 cm at final follow-up (p < 0.05). Mean VAS improved from 5.5 to 2.2 (p < 0.05). The mean preoperative and the final follow-up Oswestry Disability Indices were 27.8% and 13.1% respectively (p < 0.05). Conclusions Stand-alone OLIF could be regarded as an efficient and safe option in the treatment of ADS for careful selected patients.

Background & Aim: The current study aimed to investigate workplace bullying, specifically verbal abuse of working nurses, and its consequences on the physical and psychological levels. Methods & Materials: A cross-sectional study was designed and implemented in 151 nurses working at a university hospital. The survey was conducted in 2018 at a university hospital in Greece, and the Verbal Abuse Scale (G-AVQ v.0/2015) was used to assess the verbal abuse level. Multiple linear regression analysis was applied, and distributions were tested for their symmetry using Blom's method (QQ plot). Results: 88.1% were women as the mean age of all was 41.7 years and 16.1 years the mean length of employment. Almost all nurses (94.7%) reported experiencing verbal abuse, as 77.6% reported that the perpetrator was a patient's relative (p<0.05). Among cognitive assessment, coping, severity of effects, and strength of feeling, coping had the highest mean value the highest mean value, while severity of effects had the lowest (2.52 vs. 1.83, p<0.05). Multiple linear regression analysis showed that frequency of verbal abuse type has a significant correlation with higher coping (β=0.28, p=0.007) and strength of feeling values (β=0.29, p=0.010). Similarly, the severity of verbal abuse type has a significant correlation with higher strength of feeling values (β=0.30, p=0.014). Conclusion: Almost all the nurses reported experiencing verbal abuse as the 'patients' relatives were the main perpetrators. Although the nurses seem to cope with verbal abuse successfully, this fact is described as stressful. Moreover, the frequency, severity of verbal abuse, and consequences are correlated to the emotions that arise from it.

Abstract The purpose of this study was to evaluate the impact of emphysematous changes in lung on dosimetric parameters in stereotactic body radiation therapy (SBRT) for lung tumor. A total of 72 treatment plans were reviewed, and dosimetric factors [including homogeneity index (HI) and conformity index (CI)] were evaluated. Emphysematous changes in lung were observed in 43 patients (60%). Patients were divided into three groups according to the severity of emphysema: no emphysema ( n = 29), mild emphysema ( n = 22) and moderate to severe emphysema groups ( n = 21). The HI ( P &lt; 0.001) and the CI ( P = 0.029) were significantly different in accordance with the severity of emphysema in one-way analysis of variance (ANOVA). The HI value was significantly higher in the moderate to severe emphysema group compared with in the no emphysema (Tukey, P &lt; 0.001) and mild emphysema groups ( P = 0.002). The CI value was significantly higher in the moderate to severe emphysema group compared with in the no emphysema group ( P = 0.044). In multiple linear regression analysis, the severity of emphysema ( P &lt; 0.001) and the mean material density of the lung within the PTV ( P &lt; 0.001) were significant factors for HI, and the mean density of the lung within the PTV ( P = 0.005) was the only significant factor for CI. The mean density of the lung within the PTV was significantly different in accordance with the severity of emphysema (one-way ANOVA, P = 0.008) and the severity of emphysema ( P &lt; 0.001) was one of the significant factors for the density of the lung within the PTV in multiple linear regression analysis. Our results suggest that emphysematous changes in the lung significantly impact on several dosimetric parameters in SBRT, and they should be carefully evaluated before treatment planning.

The contribution degree of different surface factors (complexity and heterogeneity) in the urban interior to the urban thermal environment has become an issue of increasing concern under changing climate. In this paper, the multiple linear regression analysis methods to analyze the contribution degree of different surface factors to the urban thermal environment were based on seven urban built-up areas. At the same time, the LST of the same type of factors in the same city will have a difference of ±2.5°C due to the different surrounding features. At the same time, the LST of the same ground object in the same city will be ±2.5°C different because of the difference of the surrounding ground object. The environmental LST and the mean LST of other surface factors were significantly correlated, and the root mean square error was 3.52. This study first classifies the ground features with different attributes, conducts LST statistics for each category, and conducts multivariate linear analysis, instead of setting some fuzzy exponent and forcing a threshold to calculate. The purpose is to explore the contribution of different reflectivity ground objects to the urban thermal environment.

Background: Late preterm infants suffer from several problems after birth, and the key factor in fighting these problems is effective breastfeeding. Objective: To determine breastfeeding self-efficacy and its relationship with perceived stress and assess breastfeeding performance in mothers with late preterm infants Methods: In this prospective study, 171 eligible nursing mothers with late preterm infants born in Alzahra Medical Center of Tabriz, Iran, were selected via convenience sampling. The Breastfeeding Self-Efficacy Scale-Short Form was employed to measure breastfeeding self-efficacy, and the 14-item Perceived Stress Scale was used to measure the perceived stress 24 hours after giving birth. When the child was 4 months old, breastfeeding performance was measured by the Standard Breastfeeding Performance Questionnaire. The data were analyzed by Pearson and Spearman’s correlation tests, independent t-test, one-way ANOVA, and multiple linear regression analysis. Results: The mean (standard deviation) of breastfeeding self-efficacy was 50.0 (7.8) with scores ranging from 13 to 65, and the mean (standard deviation) of perceived stress was 26.5 (8.8) with scores ranging from 0 to 56. The median (25-75 percentiles) of breastfeeding performance score equaled 2.0 (1.0 to 3.0) with scores ranging from 0 to 6. Based on multiple linear regression analysis and after adjusting the personal-social characteristics, by increasing the score of breastfeeding self-efficacy, perceived stress was significantly decreased (B=-0.1, 95%CI=-0.3 to 0.0). However, there was no statistically significant relationship between breastfeeding self-efficacy and breastfeeding performance (p=0.418). Conclusion: Due to the possibility of adjusting breastfeeding self-efficacy and its role in mothers’ perceived stress, developing proper strategies seems to be essential for enhancing breastfeeding self-efficacy.

Background: Successful Aging (SA), as one of the most important indicators of elderly people's health, has received substantial attention in the gerontological literature. Objective: The present study aimed to identify the successful aging status and its associated factors. Methods: A cross-sectional study was conducted using the stratified multistage sampling method. In 2015, a total of 600 community-dwelling participants aged 60 years or older in Tehran participated in this study. The SA was measured by a validated questionnaire consisting of seven dimensions. A Stepwise multiple linear regression analysis was done using SPSS to identify the most important predictors of SA. Results: The mean age of the participants was 69.7 (SD=7.5), and around 46% of them were retired. The mean score of the composite index of the SA was 65.6 (SD=10.8; expected range 0-100). The results of the study showed that 11.2% of the participants were aging successfully. The results of the stepwise multiple linear regression analysis revealed that childhood health status, socioeconomic status in childhood, level of education, marital status, income, and the number of diseases are significantly contributed to successful aging. Conclusion: The results of the present study showing only a few of the participants are aging successfully, imply that social and health policymakers must pay more attention to the aging population, particularly those with low social status and chronic medical status.

BACKGROUND: Adult degenerative (de novo) scoliosis (ADS) usually occurs due to degenerative changes and is accompanied by progressive low-back pain and/or symptomatic lumbar stenosis. Interlaminar decompression is considered an effective treatment of lumbar stenosis, but some surgical contraindications to traditional open surgery limit its application in elderly patients with many disorders. A 10-mm endoscope has been used in the treatment of stenosis in individuals with ADS and its safety and efficacy should be assessed. OBJECTIVE: The objective was to conduct a retrospective analysis to compare interlaminar decompression with a 10-mm endoscope versus a microscope. STUDY DESIGN: Retrospective study. SETTING: This study took place at the First Affiliated Hospital of Harbin Medical University. METHODS: The data of 34 ADS patients treated in our hospital from January 2018 to December 2019, who underwent decompression with a 10-mm endoscope (ES group, 19 patients) or microscope (MS group, 15 patients) were retrospectively reviewed. The two methods were compared using the visual analog scale (VAS), Japanese orthopedic association (JOA) scale, and Oswestry disability index (ODI). Lumbar stability was also evaluated by the progression of scoliosis. RESULTS: There were no significant differences between the 2 groups in demographic or clinical characteristics. The mean preoperative Cobb angle of all patients was 23.34° ± 6.44°, which indicated degenerative scoliosis. The mean JOA and ODI scores were 8.09 ± 1.44 and 55.47 ± 11.91. The mean preoperative pelvic incidence (PI) and lumbar lordosis (LL) angles were 51.02° ± 7.21 and 38.26° ± 6.98 and the mean PI-LL mismatch was 12.76° ± 5.63. There was no significant difference in the VAS scores for back/leg pain between the groups at 1 week after the operation, but the scores of the ES group were significantly higher than those of the MS group at 3 months and 12 months. There were no significant differences of mean JOA and ODI between the ES and MS groups preoperatively, at 3 months, or at 12 months, but the JOA and ODI scores of the ES group were significantly higher than those of the MS group 1 week after the operation. LIMITATIONS: The study showed that a novel method for the minimally invasive treatment of ADS is feasible; the safety and outcomes of this method should be verified with more cases. CONCLUSIONS: Minimally invasive decompression with a 10-mm endoscope was suggested to be a safe and effective method, as expected, for the treatment of lumbar stenosis in ADS patients.

Abstract Background The parotid gland accounts for significant soft tissue volume in the face and is therefore of central relevance to facial and neck rejuvenation. Objectives To determine how parotid gland volume is predicted by age and other factors. Methods We conducted a retrospective longitudinal study of patients with multiple computed tomography (CT) scans of the neck performed at least 7 years apart. Parotid gland volumes were measured and multiple linear regression analysis was performed to model the relations between age, BMI and parotid volume. Results The study cohort comprised 70 patients. The mean (SD) ages at initial and final imaging time points were 47.5 (12.6) and 58.8 (12.2) years old, with an average of 11.3 years elapsed between CT scans. The mean (SD) parotid gland volume increased from 28.7 (10.0) cc to 32.2 (10.7) cc over the average 11.3 year period (P = 0.03). However, the results of the multiple linear regression analysis show that when controlling for body mass index (BMI) and sex, age alone does not predict parotid volume (P = 0.29). BMI was directly correlated with gland volume (P &lt; 0.01). An increase of 1.0 kg/m 2 in BMI predicted an increase in parotid volume by 1.1 cc. Male sex was also associated with significantly greater parotid volume. Conclusions Mean parotid volume increased over time but these gains were driven by increases in BMI and not age alone. These findings are highly relevant to the treatment of the aging face and neck.
