ing preoperative MRI data. Automated quantitative MRI analysis can be quickly and reliably performed in patients with frontal lobe epilepsy, and further studies may be developed for integration into preoperative risk stratification.

In observational studies, patients with chronic kidney disease (CKD) exhibited a controversial risk of atrial fibrillation (AF) recurrence following radiofrequency (RF) or cryoballoon ablation compared with non-CKD patients. This meta-analysis analysed the impact of CKD on AF recurrence following ablation.

We searched the PubMed, Embase, ProQuest, ScienceDirect, Cochrane Library, ClinicalKey, Web of Science, and ClinicalTrials.gov databases for articles published between January 1, 2010, and May 31, 2020. In total, seven observational studies with 23468 patients were analysed. Data included demographics, AF classification, left atrial size, incidence of AF recurrence, and ablation method.

The prevalence of CKD was 8.0% (7.6%-24.4%) in the AF ablation population. The CKD population was older and had a higher prevalence of diabetes mellitus, hypertension, and heart failure, a higher CHA2DS2-VASc score, larger left atrial dimension, and lower left ventricular ejection fraction compared with the non-CKD population. The CKD patients had a higher AF recurrence rate following ablation than non-CKD patients (odds ratio [OR], 3.71; 95% confidence interval (CI), 1.35-10.19). CKD was associated with higher AF recurrent risk after ablation in patients with only paroxysmal AF (OR=4.81, 95% CI 2.48-9.35). CKD was associated with higher AF recurrent risk in patients receiving radiofrequency ablation (OR=3.28, 95% CI 2.17-4.94) or cryoballoon ablation (OR=6.50, 95% CI 2.24-18.89) and in Asian region (OR=4.86, 95% CI, 2.69-8.78).

Some interactions are obligate (essential for survival) while others are facultative (usually beneficial but not essential). Not all individuals host all facultative symbionts in a population, and thus there is probably a trade-off between the cost of hosting these symbionts and the benefits they confer to the host. Plant-sucking insects have been one of the most important models to test these costs and benefits experimentally. This research is now moving beyond the description of symbiont effects towards understanding the mechanisms of action, and their role in the wider ecological community. We present a quantitative and systematic analysis of the published evidence exploring this question. We found that whitefly and true bugs experience benefits through increased growth and fecundity, whereas aphids experience costs to their fecundity but benefits through increased resistance to natural enemies. We also report the lack of data in some plant-sucking groups, and explore variation in effect strengths and directions across aphid host, symbiont and plant species thus highlighting the importance of considering the context dependency of these interactions.The current mixed-method study examined the role of natural mentors in the cyclical process of college students’ sociopolitical development, particularly their critical consciousness. College students (N = 145) completed surveys at two time points over a one-year period. Path analyses indicated that critical action and perceived inequalities were significantly associated with more social justice conversations with mentors and that having more social justice conversations with mentors was significantly associated with more critical action and perceived inequality. Further, mentoring conversations and sociopolitical efficacy helped to explain the positive role of perceived inequality and action on later attitudes around perceived inequalities and critical action. check details Qualitative one-on-one interviews of a subset of participants (n = 30) expanded findings from the quantitative data and revealed detailed information about how mentors supported youth critical consciousness. Specifically, mentors engaged in 1) dialogue and reflection, 2) information and resource sharing, 3) nonjudgmental, comfortable conversations, and 4) role modeling. Findings inform the iterative nature of critical consciousness and on how older adolescents leverage support from natural mentors in this process.

The aim of this study is to evaluate dysfunctional high-density lipoprotein cholesterol (HDL) by measuring myeloperoxidase (MPO)/paraoxonase 1 (PON1) ratio in patients with rheumatoid arthritis (RA) and to investigate the relationship between dysfunctional HDL and cardiovascular disease (CVD) in RA patients.

Sixty-seven healthy individuals and 130 RA patients were included in the study. Routine lipid panels (triglyceride (TG), low-density lipoprotein cholesterol (LDL), HDL, total cholesterol (TC), PON1 and MPO levels were measured. Disease activity scores-28 (DAS28) of RA patients were calculated. Cardiological examination records of the patients were assessed to detect patients who also have CVD.

There were no significant differences between RA and control groups in routine lipid profiles (P>.05 for all). MPO/PON1 ratios were significantly elevated in the RA group compared with the control group (P<.001). MPO/PON1 ratios were higher in RA patients with CVD history compared with those without CVD (P<.05). MPO/PON1 ratios were correlated with DAS28 scores (rho 0.357, P<.001).

HDL dysfunction determined by the MPO/PON1 ratio may be associated with the pathophysiology of increased CVD in RA. Thus, evaluating dysfunctional HDL levels by measuring the MPO/PON1 ratio in RA patients may allow more detailed patient follow-up, as well as the reduction of CVD events in RA patients with therapeutic agents aiming to increase the functional properties of HDL by decreasing this ratio.
