Purpose/objective: The purpose of this research is to investigate the influence of the 2008 xenophobic events on the structure of earnings of street traders in inner-city Johannesburg and to provide recommendations to policymakers.Problem investigated: The xenophobic events of 2008 are well documented, but absent from the literature is the potential influence on the earnings of foreign street traders. This study investigates this influence through analysis of data from before and after the events.Design and methodology: The study applies an exploratory cross-sectional research design using data from three different samples. Mann-Whitney and Chi-squared measures are applied together with exploratory multiple linear regression analysis to generate insight into the relationships between earnings and differences by origin.Findings and implications: In 2009 the earnings structure of the sector changed. In 2008 and 2010, the earnings of foreign traders are higher, whereas in 2009 these traders earned less than local traders. It is argued that the xenophobic events might have resulted in a temporary restructuring of earnings.Originality or value of the research: This study makes a contribution through exploratory findings that document a change in the structure of earnings of foreign street traders.Conclusion: A change in the structure of earnings of foreign street traders occurred after the xenophobic events of 2008. Although association cannot ascribe causality, it is argued that this change may be related to these events.

Abstract Background: pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections syndrome (PANDAS) identifies patients with acute onset of obsessive-compulsive and tic disorders. The objective of this study was to assess NOX2 levels, as well as serum 8-iso-prostaglandin F2α (iso-PGF2α) and lipopolysaccharide (LPS) derived from Gram-negative bacteria in the gut of patients with PANDAS. Methods: a cross sectional study was performed to compare serum levels of soluble NOX2-dp (sNOX-2-dp), isoprostanes and LPS in 60 consecutive subjects, including 30 children affected by PANDAS and 30 controls (CT) matched for age and gender. Serum zonulin was used to assess gut permeability. Results: compared with CT, PANDAS children had higher values of sNOX-2-dp, 8-iso-PGF2-alpha and LPS. Simple linear regression analysis showed that sNOX2-dp was significantly correlated with serum LPS (Rs=0.359; p=0.005), zonulin (Rs=0.444; p<0.001) and iso-PGF2α (Rs=0.704; p<0.001). LPS significantly correlated with serum zonulin (Rs=0.610; p<0.001), and iso-PGF2α (Rs=0.591; p=0.001). A multiple linear regression analysis was performed to define the independent predictors of sNOX-2-dp. Isoprostanes and zonulin emerged as the only independent predictive variables associated with sNOX2-dp (R2=68%). Conclusion: this study provides evidences that children affected by PANDAS have high circulating levels of sNOX2-dp, isoprostanes and of LPS that could be potentially implicated in the process of neuroinflammation.

SUMMARY OBJECTIVES To compare the serum concentrations of adipokines resistin and chemerin in children and adolescents with eutrophic and overweight and to evaluate their relationship with anthropometric, biochemical, and blood pressure variables. METHODS a cross-sectional epidemiological study was conducted with 234 students enrolled in public elementary schools in the city of Juiz de Fora / MG. Anthropometric evaluation, biochemistry, and blood pressure measurement were performed. Statistical analyzes included the Student-t or Mann-Whitney tests, Pearson or Spearman correlation, used according to the distribution of the variables, and linear regression analysis, by means of the evaluation of the effect of the independent variables on the serum levels of chemerin and resistin, adjusted for age and sex. For the data analysis, SPSS® software version 21.0 and STATA® version 10.1 were used, assuming a significance level of 5%. RESULTS the concentrations of chemerin were higher in eutrophic individuals than in those with excess weight (p> 0.05). In contrast, levels of resistin were higher in the young with excess weight than in the eutrophic ones (p <0.05). In the multiple linear regression analysis, the levels of chemerin were associated with the values of resistin, systolic, and diastolic blood pressure. Resistance levels maintained association only with BMI and chemerin values. CONCLUSION the adipokines analyzed presented a distinct profile in the groups of children and adolescents with eutrophic and overweight.

Background: Medication adherence is key to secondary prevention in patients with stroke. Poor medication adherence can lead to recurrence, disability, or even death in stroke survivors. Patient activation is associated with increased healthy behaviors and improved clinical outcomes in many chronic diseases. However, the association between patient activation and medication adherence in patients with stroke remains unclear.Objective: The study aimed to explore the influence of patient activation on the medication adherence of patients with stroke and to analyze the reasons for medication nonadherence.Materials and Methods: A cross-sectional design with convenience sampling was used in this study. A total of 119 patients with stroke were recruited from a tertiary hospital in Guangzhou. A social-demographic and clinical data form, a self-developed medication adherence questionnaire, and the 13-item Patient Activation Measure (PAM-13) were used. Univariate analysis and multiple linear regression analysis with dummy variables were conducted to investigate the associations between medication adherence and patient activation. Data were analyzed with IBM® SPSS® version 25.0.Results: The mean PAM-13 score in patients with stroke was 51.56 ± 12.58. A low level of patient activation was reported by up to 66.4% of the patients. The self-reported medication adherence questionnaire score was 5.59 ± 1.52. A low level of medication adherence was reported by up to 59.7% of the patients, while a moderate level was reported by 34.4%, and a high level was reported by only 5.9%. In the multiple stepwise regression analysis, patient activation was found to be an independent influencing factor of medication adherence in patients with stroke (p &lt; 0.05).Conclusion: Medication adherence was poor in patients in Guangzhou, China, following an ischemic stroke. Patient activation as the independent influencing factor identified in this study will support healthcare givers to develop the tailored intervention to improve medication adherence among patients with stroke in China.

Abstract Background Fear of workplace violence has become a critical issue worldwide, which can lead to burnout, low levels of job satisfaction, and turnover. However, to date, little attention has been directed toward fear of workplace violence among nurses. Accordingly, this study investigated the level of fear of future workplace violence and its influencing factors among nurses in Shandong, China. Methods A cross-sectional study was conducted from July 30 through September 30, 2020 in Shandong Province, China. A total of 1898 nurses were enrolled from 12 tertiary hospitals. Fear of future workplace violence was measured using the Fear of Future Violence at Work scale. Demographic information, employment characteristics, social support, and experience of workplace violence were assessed. Multiple linear regression analysis was used to explore the influencing factors of fear of future workplace violence. Results The average score of fear of future violence at work was 67.43 ± 17.20 among nurses. Multiple linear regression analysis showed that higher fear of future violence at work scores were reported among nurses who were female (B = 7.10, p < 0.001), married (B = 3.50, p = 0.028), with a monthly income ≥5000 Chinese yuan (CNY) (B = 3.14, p = 0.007), working in the department of internal medicine (B = 2.90, p = 0.032), surgery (B = 5.03, p < 0.001), pediatrics (B = 5.38, p = 0.003), or emergency department (B = 4.50, p = 0.010), working as a contract employee (B = 2.41, p = 0.042), or who had experienced workplace violence (B = 7.02, p < 0.001). Lower fear of future violence at work scores were found among nurses who took vacations (1–14 days: B = − 2.52, p = 0.047; ≥15 days: B = − 3.69, p = 0.007) and had a high-level of social support (B = − 2.03, p = 0.020). Conclusions There was a high level of fear of future workplace violence among nurses in Shandong, China. This should be considered an important issue by hospital administrators and government officials. Effective interventions need to be enacted to address the influencing factors of fear of future workplace violence.

Background: Some previous studies have shown reduced levels of plasma B-type natriuretic peptide (BNP) in individuals with obesity. We aimed to estimate the relationship between BNP and abdominal fat distribution, adjusted for confounding factors. Methods: This cross-sectional study included 1806 Japanese individuals (981 men and 825 women) who underwent a medical health check-up. Analyzed data included age, sex, visceral fat area (VFA), and subcutaneous fat area (SFA) as obtained from computed tomography, blood pressure, and blood test results including BNP. Multiple linear regression analysis was used to examine the association between BNP, VFA, and SFA after adjusting for age, sex, comorbidities, and body mass index. Results: In the models analyzed separately for VFA and SFA, BNP correlated independently with VFA in multiple linear regression analysis among all subjects and in both men and women, while SFA correlated inversely with BNP in all subjects and women but not in men. In the model that included both VFA and SFA, BNP correlated independently with VFA, but SFA and BNP were not correlated in any models. Conclusion: Higher VFA showed an independent, significant association with lower BNP. In addition, the inverse correlation with BNP was stronger for VFA than for SFA.

Abstract Background The purpose of this study was to investigate the association between the severity of the mandibular inferior cortex (MIC) porosity and the number of remaining teeth in elderly Indonesian people.Materials and methods This cross-sectional study was conducted by measuring secondary data on panoramic digital examinations of patients aged 50 years and older. A total of 428 panoramic radiographs were measured from January 2017 to December 2018. The number of remaining teeth (including the third molars) was evaluated. Mandibular porosity was measured by using panoramic radiographs, according to the MIC classification: normal; mildly to moderately eroded; and severely eroded cortex.Statistical analysis used Data analysis was done using Mann-Whitney nonparametric tests to verify the relationship between the MIC classification and the number of remaining teeth. Multiple linear regression analysis was performed to investigate the relationship between confounding variables.Results A significant correlation was found between MIC classification and the number of remaining teeth on the Mann-Whitney test (P < 0.001). Multiple linear regression analysis showed that MIC classification was significantly associated with the value of the number of remaining teeth after controlling for gender and age (β = -0.37, R2 = 0.22, P < 0.001). Subjects with MIC class 3 were 7.14 times more likely to lose their teeth than subjects with MIC class 1 or class 2.Conclusions Our study demonstrated that there was an association between the severity of mandibular inferior cortex porosity and the number of remaining teeth in elderly Indonesian people.
