Mean ± standard deviation knowledge scores improved from 14.0 ± 4.5 before the class to 16.5 ± 6.5 after the class (P = .008). Anxiety scores (n = 33) improved from 35 ± 13 before the class to 33 ± 12 after the class (P = .047). Conclusion On this surgical mission trip, underserved patients' knowledge about total joint arthroplasty increased only modestly after taking a preoperative class. Greater understanding of how to educate patients and reduce their anxiety on medical missions is needed.Background Debridement, antibiotics, and implant retention (DAIR) is an appealing treatment option for periprosthetic joint infection (PJI) due to its low cost and low morbidity. There are many nonmodifiable risk factors for DAIR failure that have previously been established. A dual DAIR setup constitutes establishing a new, sterile field after the initial debridement. The purpose of this study is to determine whether the modifiable surgical technique of a dual setup improves the infection control rate following PJI. Methods A retrospective study was conducted from January 1, 2000 to December 31, 2017 to identify patients who underwent a DAIR procedure as initial surgical treatment for PJI of the hip or knee. Patients were divided between 2 groups, failed and successful DAIR procedures. Failure was defined as infection recurrence requiring surgical intervention. Demographic (age, gender, body mass index, smoking status, American Society of Anesthesiologists status), preoperative comorbidity (hypertension, cardiac disease, diabetes status, depression or anxiety diagnosis, pulmonary disease), operating surgeon, single vs dual setup, hospital, use of long-term antibiotics postoperatively (greater than 6 weeks of intravenous antibiotics), joint, and laterality data were compared between cohorts using multivariate regression analysis. Results Two hundred sixty-three patients were identified who underwent DAIR as the exclusive and initial treatment for PJI. Single vs dual setup, knee vs hip joint, cardiac or vascular disease diagnosis, major depressive disorder or generalized anxiety disorder diagnosis, and staphylococcal infections were found to be independent predictive variables for DAIR failure. Conclusion In our series, the dual setup DAIR was a modifiable surgical technique that significantly decreased the risk of infection recurrence compared to single setup DAIR.Background and aim Findings on the effects of zinc supplementation on the lipid profile in patients with type 2 diabetes mellitus (T2DM) are conflicting. The current comprehensive systematic review and meta-analysis aimed to summarize available evidence in this regard. Methods and results After a systematic search in the online databases, we included the randomized controlled trials (RCTs) investigating the effect of zinc supplementation on lipid profile [total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and triglyceride (TG)] in patients with T2DM. Altogether, 9 studies with a total sample size of 424 patients with T2DM were included in the analysis. Combining 9 effect sizes from 9 RCTs, we found a significant lowering effect of zinc supplementation on serum levels of TG (weighted mean difference (WMD) -17.08, 95% CI -30.59, -3.58 mg/dL, P = 0.01) and TC (WMD -26.16, 95% CI -49.69, -2.62 mg/dL, P = 0.02). Although the overall effect of zinc supplementation on LDL-C levels was not significant, a beneficial effect was seen in studies that administered less then 100 mg/d zinc. Based on the non-linear dose-response analysis, a greater reduction in serum levels of TC and LDL-C following zinc supplementation was seen at less then 12 weeks' duration of intervention. Unlike the overall effect size, we found a significant increasing effect of zinc supplementation on serum HDL-C concentrations in most subgroups of RCTs according to the subgroup analyses. Conclusion We found that zinc supplementation may beneficially influence lipid profile in patients with T2DM.Background and aims Evaluating associations of circulating electrolytes with atrial fibrillation (AF) and burden of supraventricular arrhythmias can give insights into arrhythmia pathogenesis. Methods and results We conducted a cross-sectional analysis of 6398 participants of the Atherosclerosis Risk in Communities (ARIC) study, ages 71-90, with data on serum electrolytes (magnesium, calcium, potassium, phosphorus, chloride, sodium). Prevalence of AF was determined from electrocardiograms and history of AF hospitalizations. A subset of 317 participants also underwent electrocardiographic recordings for up to 14 days using the Zio® patch. Burden of other supraventricular arrhythmias [premature atrial contractions (PACs), supraventricular tachycardia] was determined with the Zio® patch. We used logistic and linear regression adjusting for potential confounders to determine associations of electrolytes with arrhythmia prevalence and burden. Among 6394 eligible participants, 614 (10%) had AF. Participants in the top quintiles of magnesium [odds ratio (OR) 0.82, 95% confidence interval (CI) 0.62, 1.08], potassium (OR 0.82, 95%CI 0.68, 1.00), and phosphorus (OR 0.73, 95%CI 0.59, 0.89) had lower AF prevalence compared to those in the bottom quintiles. No clear association was found for circulating chloride, calcium or sodium. Higher concentrations of circulating calcium were associated with lower prevalence of PACs in the 12-lead electrocardiogram, while higher concentrations of potassium, chloride and sodium were associated with higher PAC prevalence. Circulating electrolytes were not significantly associated with burden of PACs or supraventricular tachycardia among 317 participants with extended electrocardiographic monitoring. Conclusion Concentrations of circulating electrolytes present complex associations with selected supraventricular arrhythmias.

Traditional risk factors do not seem to fully explain this process in patients with SLE and no other imaging/serum biomarkers have so far improved risk stratification. Here, we focused on the role of adiponectin in women with SLE. Methods and results This is a sub-analysis of a validated cohort enrolling eighty females (age 18-65 years) affected by SLE. Patient underwent a single blood sampling and carotid echography. Serum adipocytokines (i.e. leptin, resistin and adiponectin) were assessed by enzyme-linked immunosorbent assay (ELISA). Patients with a carotid plaque (n = 23) were older, with longer duration of the disease, chronic use of corticosteroids, and immunosuppressive therapies. As expected, patients with a carotid plaque had increased vascular risk and high serum levels of inflammatory biomarkers, total and LDL cholesterol and adiponectin. Significant positive correlation between serum adiponectin and presence of a carotid plaque was found independently of patient age, SCORE Risk Charts, duration of disease, and SLE treatments.
