Abstract Background: The purpose of this study to evaluate the potential relationship between the periosteal reaction and medial compartment knee osteoarthritis (KOA), and to assess the related risk factors for the development of periosteal reaction associated with medial compartment KOA.Methods: From January 2019 to December 2019, a total of 476 consecutive patients with medial compartment KOA were included and assessed in this retrospective comparative study. They were divided into two groups: periosteal reaction group and non-periosteal reaction group. Radiological parameters was measured for malalignment of the lower extremities in coronal plane. Intra-observer and inter-observer reliabilities of all radiological measurements were analyzed by intraclass correlation coefficients (ICCs). Univariate analyses was conducted for comparison of differences with continuous variables between patients with periosteal reaction and without periosteal reaction. Multivariate binary logistical regression analysis were performed to determine the independent risk factors of radiographic parameters for periosteal reaction.Results: A total of 363 patients (726 knees) were selected for the study, including 91 males and 272 females, with an average age of 57.9±12.8 years (range, 18-82 years). The overall incidence of periosteal reaction associated with medial compartment KOA was 56.7%. Furthermore, the incidence of periosteal reaction significantly increased with age and K-L grade progressed (P＜0.05). Multivariate logistical regression analysis found that HKA and JICA were significantly correlated with the development of periosteal reaction adjacent to the lateral of proximal tibia diaphysis in medial compartment KOA (P＜0.05).Conclusions: Our observation of the reaction of periosteum may be an anatomical adaptation for medial compartment KOA. Patients with lower HKA and higher JICA are more likely to developing periosteal reaction, which occurred most commonly adjacent to the lateral of proximal tibia diaphysis.

AbstractThis study aimed to assess the association of coagulation-related indicators such as plasma fibrinogen (FIB), d-dimer, and fibrin degradation product (FDP) in rheumatoid arthritis (RA) with the disease activity. Data from 105 RA patients and 102 age- and gender-matched healthy controls were collected in the retrospective study. Disease activity score in 28 joints based on C-reactive protein (DAS28-CRP) was used to divide RA patients into low activity group (DAS28-CRP ≤ 2.7) and active group (DAS28-CRP > 2.7). Receiver operating characteristic (ROC) curve was applied to determine area under the curve (AUC). The association between plasma FIB, d-dimer, and FDP and DAS28-CRP was evaluated by spearman correlation. Logistical regression analysis was used to identify the independent variables associated with RA disease activity. RA patients showed higher levels of plasma FIB, d-dimer, and FDP than the controls (P < 0.01). Plasma FIB, d-dimer, and FDP were also increased in active groups of RA patients than those in inactive groups (P < 0.001). ROC curve analyses revealed that the AUC of d-dimer was higher than erythrocyte sedimentation rate (ESR) and rheumatoid factor (RF), and that of FDP was higher than RF in RA patients. In addition, the optimal cut-off value of plasma FIB, d-dimer, and FDP for RA diagnosis was 286 mg/dL, 470 μg/L, and 1.45 mg/L, respectively. Spearman analysis showed that plasma FIB, d-dimer, and FDP were positively related with DAS28-CRP (P < 0.001) in RA patients. Logistical regression analysis showed that d-dimer (odds ratio 2.862, 95% confidence interval 1.851–5.426, P < 0.001) was an independent variable associated with RA disease activity. FIB, d-dimer, and FDP were increased in RA patients and positively correlated with the disease activity of RA. d-dimer may act as a novel inflammatory indice for indicating disease activity in RA patients.

Purpose The purpose of this paper is to compare the way in which gender and propensity to risk are associated in two samples, one of entrepreneurs and the other of non-entrepreneurs, while controlling for other factors, namely, national cultures. Design/methodology/approach On the basis of data from 19 advanced countries, and by using two different samples, one of entrepreneurs and the other of non-entrepreneurs, the authors have used logistical regression analysis to analyse the relation between gender and propensity to risk has been used. Findings Findings suggest that gender and culture are much stronger in influencing risk propensity among non-entrepreneurs than among entrepreneurs. Originality/value Instead of analysing the effects of propensity to risk in entrepreneurship, as is usually done, the authors study some of its determinants, highlighting the differences between men and women.

Background: Inadequate bowel preparation can result in missed pathological lesions and cancellation of procedures thereby increasing the cost and delay in the diagnosis. Objectives: Thes aim of the study was to identify the potential predictors of inadequate bowel preparation using 2 liters of polyethylene glycol solution. Methodology: A prospective study was done, which included 138 consecutive patients who underwent colonoscopy over a period of 6 months. Patient’s demographics, medical history, and preparation quality were collected and compared. Factors associated with inadequate bowel preparation were identified by univariate statistics and multivariate logistical regression analysis. Results: Out of 138 colonoscopy procedure, 119 (86.2%) preparations were adequate and 19 (13.8%) were inadequate. The mean age of the patient was 52.62 (SD ±10.51) years. Out of which, 82 (59.4%) were male and 56 (40.6%) were female. In the multivariate regression analysis, constipation [adjusted OR 8.55, 95% CI 1.79-41.67] and non-compliance [adjusted OR 58.82, 95% CI 5.99-500] were independently associated with inadequate bowel preparation. Conclusion: Constipation, non-compliance, overweight, neurological disorders like stroke, dementia and age >60 years were associated with inadequate bowel preparation. Early identification of patients with a high risk of inadequate preparation can be salvaged with change in bowel cleaning strategy.

<p><em>Introduction:<strong> </strong>This paper addresses systematic corruption in Cameroon. Based on the literature review and a previous study, the research question was “does a culture of bribery exist in Cameroon, and what are its predictors? Method and materials</em><em>:</em><em> Data for this study was collected by the Afrobarometer project from 1,200 Cameroonian respondents Based on self-reported data, the research attempted to determine the volume of bribes paid by respondents to receive public services. Results: Overall, the findings revealed the existence of a culture of bribery in Cameroon; forty-five percent of the respondents reported paying bribes within the last year and 30 percent reported paying two or more bribes in that same time period. Logistical regression analysis revealed that 7 variables were significant predictors of payment of bribes. Being the victim of a property crime was the strongest predictor, which, in turn, drew attention to the role of the police in Cameroon’s bribery culture.</em><em></em></p>

AbstractTrees are the main roosts for several European bat species but forestry practices are most often detrimental for them. After checking for the presence or absence of bats in trees, we collected a number of variables to describe trees within a lowland sub-Atlantic oak-dominated forest. We modelled the usage of the trees by bats according to the main characteristics of trees (11 quantitative and 13 qualitative variables) with a logistical regression analysis. Our results show that the number of cavities in the tree is the main variable that induces the occupancy by bats. There is a “typical” lowland tree preferred by bats which is a healthy oak tree of large diameter. We finally provide some guidance for woodland managers to maintain bat roosts, including maintaining some trees of large diameter, protecting small areas of old trees with cavities).

This is a retrospective study that examined predictor variables for postinjury employment outcome of workers' compensation claimants with back injury. Vocational status (returned to work, not returned to work) was used to reflect employment outcome. Using a binary stepwise logistical regression analysis, we found that education, age, physical demands of the job at injury, and mandated vocational rehabilitation independently added information that enhanced the ability to predict claimants who would return to work. The findings support the position that providers of vocational rehabilitation services must be aware of the influence specific demographic and vocational factors may have on employment outcomes for workers' compensation claimants with back injury.
