Cervical carcinoma and cervical intraepithelial neoplasia (CIN) are associated with persistent infection by oncogenic subtypes of HPV (Human Papillomavirus). Factors linked to immunity, genetics and others like oral contraceptive use, sexual behavior, coinfections with other microorganisms and smoking seem to influence the mechanisms that determine regression or progression to CIN and cervical cancer. We investigated the effect of the MHC class I chain-related gene A (MICA) and Killer Cell Lectin Like receptor K1 (KLRK1) genes on cervical cancer and CIN lesions susceptibility in a group of 195 patients from southern Brazil. There were found a significantly higher number of ex-smokers in the control group (p = 0.005). There were more oral contraceptives (OC) users in the patient group. MICA*00801/04 allele showed a significant difference between patient and control groups (p = 0.03; OR = 0.63, 95% CI 0.41-0.96), as well as MICA*01801(p = 0.004, OR = 0.15, 95% CI 0.03-0.64) and MICA*00201/020 (p = 0.01; OR = 0.60, 95% CI 0.40-0.88). We also analyzed cases and controls according to the MICA-129 genotypes (Met/Val). There was found a difference (p = 0.02) with the Met/Val genotype in a higher frequency in controls and Val/Val and Val/MICA del at a higher frequency in the patient group. For the KLRK1 gene there was no significant difference between groups. This study analyzed the association between peripheral distributions of helper T cell subsets, HLA shared-epitope (SE), anti-cyclic citrullinated peptide antibody (ACPA) and clinical response to therapy in rheumatoid arthritis (RA) patients. Frequencies of IFN-γ-producing CD4+T (Th1) and IL-17A-producing CD4+T (Th17) cells were determined by flow cytometry in 167 patients (114 cases with good-response (GR) and 53 poor-response (PR) based on DAS28). HLA-DRB1 alleles for patients and 150 healthy controls were determined by PCR-SSP. We observed that 65.2% of RA patients were SE+, 63.4%ACPA+, 43.7%SE+ACPA+ and 14.9% were SE-ACPA-. Higher significantly proportions of Th1 and Th17 cells were found in RA patients than controls (P  less then  0.05) as well as in the SE+ or ACPA+RA patients compared to SE- and ACPA- patients. Increased frequencies of both Th subsets were found in SE+ACPA+ versus SE-ACPA- patients (P  less then  0.001) and in the PR versus GR group (P  less then  0.001). We showed significant differences for Th cells frequencies between SE+ and SE- patients in both groups, and between ACPA+ and ACPA- cases in the PR group. Our findings suggest a close link between Th1 and Th17 cells proportions and HLA-SE/ACPA in the RA patients and remarkably in the PR group which could be indicative for the importance of immune monitoring for evaluation of response to therapy. OBJECTIVE We investigated the effectiveness of tocilizumab (an anti-interleukin-6 receptor antibody) in patients with polymyalgia rheumatica (PMR). Dabrafenib METHODS We performed a systematic literature review from the inception dates until August 7, 2019 for articles reporting tocilizumab administration to treat isolated PMR. RESULTS We identified 59 patients with isolated PMR treated with tocilizumab. All studies used intravenously administered tocilizumab at a dose of 8 mg/kg monthly. Tocilizumab monotherapy was administered to 24 and combination therapy (tocilizumab + glucocorticoid) to 35 patients. Tocilizumab monotherapy achieved low disease activity scores in only 17% of patients at week 4 and in only 71% patients even at week 12. Compared to glucocorticoid monotherapy, the reduction in the cumulative glucocorticoid dose was between 58% and 70% using a combination of tocilizumab and glucocorticoids, and 33-100% of the patients eventually showed glucocorticoid-free remission. All relapses occurred in patients administered tocilizumab monotherapy. No new safety event was reported. CONCLUSION Tocilizumab is effective in cases of isolated PMR, particularly in combination with glucocorticoids. In addition to its glucocorticoid-sparing effect, it achieves glucocorticoid-free remission and reduces relapse rates. Tocilizumab monotherapy is not recommended. Major adverse cardiac events are common causes of perioperative mortality and major morbidity. Preventing these complications requires thorough preoperative risk assessment and postoperative monitoring of at-risk patients. Major guidelines recommend assessment based on a validated risk calculator that incorporates patient- and procedure-specific factors. American and European guidelines define when stress testing is needed on the basis of functional capacity assessment. Favoring cost-effectiveness, Canadian guidelines instead recommend obtaining brain natriuretic peptide or N-terminal prohormone of brain natriuretic peptide levels to guide postoperative screening for myocardial injury or infarction. When conditions such as acute coronary syndrome, severe pulmonary hypertension, and decompensated heart failure are identified, nonemergent surgery should be postponed until the condition is appropriately managed. There is an evolving role of biomarkers and myocardial injury after noncardiac surgery to enhance risk stratification, but the effect of interventions guided by these strategies is unclear. OBJECTIVES Postpericardiotomy syndrome (PPS) is a relatively common complication after cardiac surgery. However, long-term follow-up data on the adverse events and mortality of PPS patients requiring invasive interventions are scarce. METHODS We sought to assess the occurrence of mortality, new-onset atrial fibrillation (AF), cerebrovascular events, and major bleeds in PPS patients requiring medical attention in a combination database of 671 patients who underwent isolated surgical aortic valve replacement with a bioprosthesis (n = 361) or mechanical prosthesis (n = 310) between 2002 and 2014 (Cardiovascular Research Consortium-A Prospective Project to Identify Biomarkers of Morbidity and Mortality in Cardiovascular Interventional Patients [CAREBANK] 2016-2018). PPS was defined as moderate if it resulted in delayed hospital discharge, readmission, or medical therapy because of the symptoms; and severe if it required interventions for the evacuation of pleural or pericardial effusion. RESULTS The overall incidence of PPS was 11.
