Published: December 2020

Abstract
The Air Quality Index (AQI) is an air quality standards pointer based on air pollutants that have negative impacts on human health and the environment.Due to many human achievements, air pollution is increasing very rapidly and it is the introduction of chemicals, particles or organic materials into the atmosphere that harms the human environment and the natural environment.Indeed, air pollution in metropolitan and industrial cities is one of the major environmental problems. Therefore it is very important to predict pollution and avoid these problems.One of the most exciting and difficult functions is the forecast of air pollution using data mining. Many systems are intentionally help with data storage, inventory management, and convenient data creation.India's air quality indicator is a standard measure used to indicate pollution (so2, no2, rspm, spm, etc.) from time to time. The main objective of the current study is to estimate the temporal AQI used by the previous day AQI and to predict and visualize the temporal data mine using a slope interval and an arbitrary forecasting process of climate change. In Navigation Forecast, we divide the database into 85% data and 15% data based on data testing and training to determine seasonal variations and styles. Balancing problems are often exploited by problems and forecasting uses an arbitrary forecasting process and gradient idle time. Air quality forecast based on at least one year's forecast as a reliable slope using historical data of previous years and a persistent problem.

Abstract
Background. Researchers have demonstrated that GSDMB is highly expressed in cancer tissues and located in amplicons, genomic regions that are often amplified during cancer development. We evaluated the role of GSDMB in bladder cancer using publicly available data.Methods. The relationship between clinical correlation features and GSDMB were analyzed with the Wilcoxon rank sum test (2 groups), Kruskal-Wallis test (multiple groups) and logistic regression. Clinicopathologic characteristics associated with overall survival in TCGA patients using Cox regression and the Kaplan-Meier method. Gene Set Enrichment Analysis (GSEA) was performed using TCGA data set. Results. GSDMB was differentially expressed between the tumor group and the normal group and was highly expressed in the tumor group. Reduced GSDMB expression in BLCA as significantly associated with grade (OR = 4.55, High Grade vs. Low Grade), clinical stage (OR = 2.34, Ⅱvs. Ⅳ), status (OR = 0.51 survival vs. death), all p-values <0.05. Kaplan-Meier survival analysis showed that BLCA with GSDMB- low had a worse prognosis than that with GSDMB-high (p = 0.001). The univariate analysis revealed that GSDMB- low correlated significantly with a poor overall survival (OS) (HR: 0.93; 95%CI: 0.89-0,98; p = 0.006). The multivariate analysis revealed that GSDMB remained independently associated with overall survival, with a HR of 0.711 (CI: 0.55-0.92; p = 0.009). GSEA show that focal adhesion, pathways in cancer, small cell lung cancer, renal cell carcinoma, bladder cancer and other cancer related pathways are differentially enriched in GSDMB low expression phenotype. Conclusions. High GSDMB mRNA expression is an independent risk factor for excellent prognosis in bladder cancer.

Abstract
Objective: The purpose of this study is to investigate how multisite pain, depressive symptoms and disturbed sleep are associated with health-related quality of life (HRQoL) and work ability index (WAI) in health care workers with recurrent non-specific low back pain (LBP). Methods: 219 female health care workers suffering from recurrent non-specific LBP were recruited for the study. Multisite pain (three or more pain sites with pain intensity of 4 or more on the numeric rating scale), depressive symptoms [modified Finnish version of the nine-item Patient Health Questionnaire (PHQ─9-mFIN)], disturbed sleep, HRQoL (RAND-36) and WAI short form were assessed by validated questionnaires. Results: Depressive symptoms and disturbed sleep were significantly associated with mental HRQoL and WAI (p<0.001). Multisite pain was only significantly associated with physical HRQoL. Of the mental subscales of HRQoL, social functioning, vitality and mental health were significantly associated with depressive symptoms and disturbed sleep (p< 0.001). Of the physical subscales of HRQoL, general health, bodily pain and physical functioning were significantly associated with multisite pain (p<0.05). Conclusion: In female health care workers with recurrent non-specific LBP and currently able to work, depressive symptoms and disturbed sleep were associated with decreased self-reported work ability.
Applying “Stages of Readiness to Change” Model to dentists’ decisions to participate in Medicaid: An exploratory study

Published: December 2020

Abstract
Background

The Stages of Readiness to Change (SOC) behavioral model describes behavior change as a process and distinguishes individuals based on their current behavior and readiness to change that behavior. SOC can be used to improve dentists’ participation in a state public dental benefit program (Medicaid) by targeting them at different SOC with interventions, strategies, and tools tailored to those stages. Therefore, this study assessed the usefulness of using SOC to describe dentists’ attitudes towards and participation in Medicaid. Dentists’ participation in Medicaid is of interest to policymakers, and this study demonstrates a method to identify potential opportunities for intervention.
Methods

A modified SOC algorithm used data from a periodic survey of Iowa Dentists to categorize dentists (N = 514) into: 1) Pre-contemplation, 2) Considering participation (SOC contemplation and preparation), 3) Acting ( SOC action and maintenance), and 4) Risk of relapse (at risk for discontinuing participation). The four SOC stages were compared using ANOVA and Post hoc Tukey test among : Practice characteristics, Dentists Altruism scale, Attitude about Program Administration scale, Attitude about Medicaid patients scale and Perception of Importance of Medicaid Problems scale.
Results

Among survey respondents, 36% were categorized as pre-contemplation, 6% were considering Medicaid participation, 12% were acting as Medicaid providers with minimal risk of relapse, and 46% were participating and at risk of discontinuing. Dentists’ attitudes towards program administration, Medicaid patients, and access to care varied across the SOC cycle.
Conclusions

Nealy 46% dentists in this analysis were identified as at risk of discontinuing participation – a much larger proportion than dentists considering Medicaid participation. Categorizing dentists using this approach has important implications for programmatic interventions. For example, policymakers targeting our study population could focus their efforts on reducing the likelihood of dentists dropping out of the program, with less emphasis targeting dentists in the Precontemplation stage.

Authors: Hu Zixuan , Swai Joel 
Published: December 2020

Abstract
Background Band ligation (BL) plays a vital role in the treatment of oesophageal varices; however, the procedure carries a considerable risk of band slippage, variceal site ulcer formation and post-treatment bleeding. Our study aimed to explore the incidence of post-BL ulcer bleeding and to identify possible associated factors.Methods We retrospectively reviewed the records of patients with oesophageal varices who underwent endoscopic haemostasis by BL at our institution between 2015 and 2020. We statistically compared the patients with post-BL ulcer bleeding and those without (controls). The outcome variable was the development of BL-induced ulcer bleeding. The patients’ demographics, clinical and laboratory parameters, BL procedure outcomes and experts’ opinions were used as the independent variables and possible associated factors. Results Of the 4579 eligible patients 388 (8.5%) presented with post-BL ulcer bleeding. Proton pump inhibitor (PPI) use was associated with a lower risk of post-BL ulcer bleeding (odds ratio, 0.77; 95% confidence interval [CI]: 0.603–0.983). The presence of high-risk stigmata indicated a 1.276 times higher risk of bleeding (CI: 1.024–1.592), and a greater number of varices was associated with an increased risk of post-BL ulcer bleeding (P = 0.007). The use of fewer bands per variceal site was associated with fewer bleeding incidents (P = 0.008), while lower haemoglobin levels were associated with a higher probability of bleeding (P = 0.007).Conclusions The overall incidence of post-BL ulcer bleeding was 8.5%. The presence of high-risk stigmata and a higher number of varices and bands per variceal site were associated with an increased risk of bleeding. Adequate haemoglobin levels and the use of adjuvant PPIs and having were protective factors.

Abstract
A single-step spectral editing 1H magnetic resonance spectroscopy (MRS) technique was used to measure fractional enrichments of glutamate and glutamine in the dorsal anterior cingulate cortex of five healthy volunteers after oral administration of [U-13C]glucose. Strong pseudo singlets of glutamate and glutamine were induced at an echo time of 56 ms using an always-on editing pulse at 2.12 ppm. At 113 ± 9 minutes after oral administration of [U-13C]glucose, fractional enrichment of glutamate was found to be 64 ± 5% with 1.7% within-subject coefficient of variation (CV) and fractional enrichment of glutamine was found to be 40 ± 10% with 11% within-subject CV. This study demonstrated that 13C labeling of both glutamate and glutamine can be measured with the high sensitivity and spatial resolution of proton MRS using a proton-only MRS technique with standard commercial hardware. Furthermore, it is now feasible to measure 13C labeling of glutamate and glutamine in limbic structures, which play major roles in behavioral and emotional responses and whose abnormalities are involved in many neuropsychiatric disorders.

Published: December 2020

Abstract
We estimate the impact of indoor face mask mandates and other non-pharmaceutical interventions (NPI) on COVID-19 case growth in Canada. Mask mandate introduction was staggered over two months in the 34 public health regions in Ontario, Canada. Using this variation, we find that mask mandates are associated with a 25 percent or larger weekly reduction in new COVID-19 cases in July and August, relative to the trend in absence of mandate. Province-level data provide corroborating evidence. We control for factors such as mobility (using Google geo-location data) and past cases. Our analysis of additional survey data shows that mask mandates led to an increase of about 30 percentage points in self-reported mask wearing in public. Counterfactual policy simulations suggest that mandating indoor masks nationwide in early July could have reduced new COVID-19 cases in Canada by 25 to 40 percent in mid-August (700 to 1,100 fewer cases per week).

Published: December 2020

Abstract
These paper aims are to study and estimate the evolution of the inequalities to the return on educational and professional investment, thus offering vast opportunities for analysis, in particular the dynamic links "profitability" - "investment". The general view is titled in the research field of human capital theory by analyzing three surveys provided by the National Statistical Institute that focus on wage-employment. We initially use a corrected Mincer model where we specify two types of regression then we will integrate the indicator of depreciation of human capital. Thus giving results that are used to understand the dynamics of individual investment choices. The results show a decrease in profitability and an increase in catch-up time (Overtaking). The study also makes it possible to understand the evolution of returns on educational and professional investments. To look for points of failure and imbalances in the education system and its relation to the labor market and to serve as a guide to government policy as it relates to long-term educational programs.

Published: December 2020

Abstract
The study used structural equation modelling (SEM) techniques to examine the mediation analysis of entrepreneurship development on the economic growth of women entrepreneurs in Nigeria. The study assumes the existence of three null hypotheses; entrepreneurship development does not mediate business performance, psychological, and knowledge of business practice indicators for economic growth. Data were collected from 500 randomly selected women entrepreneurs in Nigeria. Our results suggest that separating household and business income, maintaining a separate business account, stock-keeping, record-keeping among other were the knowledge of business practice indicators; openness to change, desire for self-independent among others were the psychological indicators, and reduced inactivity, increase in the size of the inventory among others were the business performance indicators that stimulate entrepreneurship development. The aforementioned catalyzed higher formalization, increases in capital investment among others as entrepreneurship development indices, which stimulate economic growth of contribution to personal and children school fare, reduction in financial dependence, and increase in affordable health care fee among others. We also established that entrepreneurship development mediates knowledge of business practice to economic growth.

Abstract
Purpose: The aim of this study was to identify the effect of tax incentive practise on sustainability of MSMEs during outbreak of corona virus pandemic in Ethiopia. Design/methodology/approach: In order to achieve this objective, the researchers have employed quantitative research approach with explanatory research design in which six hypotheses have been tested. The primary data was collected from 300 respondents using structured questionnaires. Multiple regression model was employed to identify the effect of tax incentives on sustainability of MSMEs in Ethiopia. Findings: According to the regression analysis, this study revealed that tax holiday, tax allowance, reduction in tax rate, accelerated depreciation, loss carry forward and tax exemption have positive and statistically significant effect on the sustainability of the MSMEs. Based on the finding of the study was concluded that the existence of tax incentive practice has positive contribution to sustainability of the micro, small and medium sized enterprise.Research limitations/implications: The current study was geographically focus on Ethiopia by considering the micro, small and medium sized enterprises sector. The subject wise was focused on the effect of the tax incentives:(tax holiday, tax allowance, tax exemption, and accelerated depreciation, reduction in tax rate, and loss carry forward) and on the sustainability of MSMEs. The study used primary data which is limited to a year of 2020. It might be improved in the future if other researchers incorporate large firms in the country and uses secondary data for analysis. Practical implications: To survive, micro, small and medium scale enterprises need the support from the government in the form of tax incentives. The role of tax incentives in enhancing the growth of micro, small and medium sized enterprises is very significant on the sustainability of MSMEs as well as the economy as a whole. Hence, the findings and recommendations of the current study might serve as an ingredient and be informative to the policy makers on MSMEs sector. It might also give a general insight to the policy makers, academician and professional groups of society and the public at large with regard to the role of effect of tax incentives on the sustainability and growth of MSMEs during outbreak of coronavirus.Originality/value: This study contributes to empirical evidence about the effect of tax incentives practices on sustainability of micro, small and medium enterprises in Ethiopia by considering tax incentive practice in terms of tax holiday, tax allowance, reduction in tax rate, accelerated depreciation, loss carry forward and tax exemption. As tax incentives theories supported the findings of this study, we have concluded that tax incentive practices provided by government have positive contribution for the sustainability and growth of micro, small and medium sized enterprises in Ethiopia

Published: December 2020

Abstract
Background: Neurological impairment during spinal deformity surgery was the most serious complication. When confronting intraoperative neurophysiological monitoring alerts, various surgical management methods such as the release of implants and decompression of the spinal cord are always performed. Transvertebral transposition of the spinal cord is rarely performed, and its role in the management of acute paraplegia is seldom reported.Methods: The authors present two patients with kyphoscoliosis experienced intraoperatively or postoperatively neurological deficits and abnormal neurological monitoring was detected during correction surgery. Acute paraplegia was confirmed by a wake-up test. Subsequent spinal cord transposition was performed. Intraoperative neurophysiological monitoring motor evoked potentials (MEP) and somatosensory evoked potentials (SEP) was performed to detect the changes during the process.Results: After transvertebral transposition of the spinal cord, the MEPs and SEPs were significantly improved in both patients during surgery. The spinal cord function was restored postoperatively and recovered to normal at the final follow-up in two patients. Conclusions： This case demonstrated that instead of decreasing the correction ratio of kyphoscoliosis, transvertebral transposition of the spinal cord under intraoperative neurophysiological monitoring could be an effective therapeutic strategy for acute spinal cord dysfunction caused by deformity correction surgeries.

Abstract
ObjectiveDynesys stabilization (DS) is utilized to preserve mobility at the instrumental segments and prevent adjacent segment pathology (ASP) in clinical practice. However, the advantages of DS method remain controversial. This meta-analysis was to compare the radiographic and clinical outcomes between DS and instrumented fusion in patients with or without grade I spondylolisthesis at a minimum follow-up period of 2 years. MethodsWe conducted a comprehensive search of PubMed, EMBASE, Cochrane, and Web of Science databases for potentially eligible articles. Clinical outcomes were assessed in terms of surgical time, intraoperative blood loss, length of hospital stay, in-hospital complications, VAS and ODI scores, screw loosening and breakage, and reoperation. Radiographic outcomes were assessed in terms of postoperative range of movement (ROM) and disc heigh. Moreover, adjacent segment degeneration (ASDeg) and adjacent segment disease (ASDis) were evaluated. Data are expressed as risk ratio or standardized mean difference with the associated 95% confidence intervals. The meta-analysis was performed using RevMan 5.3 and STATA 15.1 software.ResultsFourteen studies with 1078 patients were included in the meta-analysis. The mean durations of follow-up ranged from 26.64 ± 5.16 months to 93.6 ± 16.5 months. The DS group was associated with significantly shorter surgical time, fewer intraoperative blood loss, shorter length of hospital stay, less in-hospital complications, lower postoperative VAS scores for low-back and leg pain than the fusion group (P < 0.05). Moreover, the ROM at the stabilized segments of the fusion group decreased significantly (P < 0.01) and that at the adjacent segments increased significantly compared with those of the Dynesys group (P < 0.01). Additionally, the Dynesys group showed significantly less ASDeg than the fusion group (P < 0.01) but showed no significant advantage over the fusion group in terms of preventing ASDis (P = 0.33). Furthermore, the Dynesys group was insignificantly different from the fusion group in terms of ODI, screw loosening, screw breakage, surgical reoperation, and disc heigh at stabilized and adjacent segments (P > 0.05).ConclusionDynesys stabilization showed satisfactory clinical outcomes and provided additional benefits in preserving the motion at the stabilized segments and limiting the hypermobility at the adjacent segments compared with fusion method. Dynesys stabilization represented a complementary choice in the treatment of degenerative spinal lumbar disease with or without grade I spondylolisthesis.
