In the era of emerging options for mitral valvular intervention, we sought to characterize the relative utilization, outcomes, and posthospital dispositions of patients referred for transcatheter mitral valve repair (TMVRepair) and surgical mitral valve procedures (SMVP), by cancer-status. Leveraging the National Inpatient Sample, a representative national dataset, ICD-9 codes for all adults >18 years with co-morbid mitral regurgitation, and cancer without metastatic disease admitted from 2003 to 2015 were queried. TMVRepair was performed in 700 hospitalizations from 2012 to 2015, whereas SMVP was utilized during 12,863 hospitalizations from 2003 to 2015. During follow-up, we observed a proportional increase in TMVRepair utilization among cancer patients (vs noncancer), particularly in 2015 (14.2% vs 8.2%, p less then 0.0001). There was no difference in in-hospital mortality (1.4% vs 1.8%, p = 0.71), ischemic stroke (0.7% vs 0.6%, p = 0.97), major bleeding (8.6% vs 10.9%, p = 0.36), and home discharge (62.1% vs 65.7%, p = 0.45) by cancer-status among patients who underwent TMVRepair; but, cost of care was increased ($52,325 vs $48,832, p less then 0.0001). Similarly, there was no difference in in-hospital mortality (3.1% vs 3.4%, p = 0.36), ischemic stroke (2.6% vs 3.1%, p = 0.16) as well as the cost-of-care ($58,106 vs $58,844, p = 0.49) among those who underwent SMVP across the same period; but, cancer was associated with increased major bleeding (34.9% vs 30.5%, p less then 0.0001), and lower likelihood of home discharge (32.8% vs 38.6%, p less then 0.0001). In conclusion, TMVRepair and SMVP were associated with comparable in-hospital mortality and outcomes in cancer versus noncancer patients. However, cancer patients treated with SMVP experienced more frequent bleeding related complications compared with noncancer patients. Chagas heart disease (HD) is a chronic fibrosing myocarditis with high mortality. The PEACH study aimed to evaluate if exercise training can improve the functional capacity of Chagas HD patients with left ventricular dysfunction and/or heart failure. find more The PEACH study was a single center, parallel-group, clinical trial that randomized 30 clinical stable Chagas HD patients with left ventricular ejection fraction less then 45% or heart failure symptoms to either supervised exercise training 3 times/week for 6 months or a control group. Both groups had the same monthly pharmaceutical and nutritional counseling and usual care. Primary end point was functional capacity assessed by peak exercise oxygen consumption (peak VO2) obtained by cardiopulmonary exercise test. Secondary end points included other cardiopulmonary exercise test variables, cardiac function by echocardiography, body composition, muscle respiratory strength, and metabolic biomarkers. Peak VO2 increased among patients in exercise group from 17.60 ± 4.65 mlO2 kg-1 min-1 to 19.40 ± 5.51 mlO2 kg-1 min-1 while decreased in controls from 15.40 ± 6.30 mlO2 kg-1 min-1 to 12.96 ± 4.50 mlO2 kg-1 min-1, resulting in significant difference in change in peak VO2 between groups after 6 months (β = +4.6, p = 0.004). There were significant differences between groups in changes in anaerobic threshold (β = 3.7, p = 0.05), peak oxygen pulse (β = +2.7, p = 0.032) and maximum minute ventilation (β = +13.9, p less then 0.0001) after 6 months of intervention. In conclusion, exercise training improved functional capacity of chronic Chagas HD patients with left ventricular dysfunction and/or heart failure. INTRODUCTION The radial forearm free flap (RFFF) is a widely used tool in head and neck reconstructive surgery. It stands out as a relatively simple flap to achieve; it is versatile and has features that enable the reconstruction of complex head and neck defects. The aim of the study was to present our results using the RFFF in the reconstruction of seated defects in the head and neck area. MATERIAL AND METHODS A retrospective, observational and analytical study that included 58 cases of RFFF interventions, performed between January 2002 and July 2019. The data studied were the age and sex of the patients, location of the tumour, histological type, previous radiation therapy, number of venous anastomoses performed in the surgery and body temperature in the immediate postoperative period, at 24 and 48hours following surgery. RESULTS The percentage of viable RFFF was 82.8%. None of the variables analysed appear to be a risk factor for flap failure. The most frequent cause of flap failure was venous thrombosis. CONCLUSIONS Microvascularised flaps play an important role in reconstructive surgery, being the RFFF one of the most interesting for head and neck reconstruction. It is a very versatile tool that allows the reconstruction of many of the sites where the head and neck surgeon operates. BACKGROUND Cytokine-induced killer (CIK) cells are an ex vivo-expanded cellular therapy product with potent anti-tumor activity in a subset of patients with solid and hematologic malignancies. We hypothesize that directing CIK cells to a specific tumor antigen will enhance CIK cell anti-tumor cytotoxicity. METHODS We present a newly developed method for affixing antibodies directly to cell surface proteins. First, we evaluated the anti-tumor potential of CIK cells after affixing tumor-antigen targeting monoclonal antibodies. Second, we evaluated whether this antibody-conjugation method can profile the surface proteome of CIK cells. RESULTS We demonstrated that affixing rituximab or daratumumab to CIK cells enhances cytotoxic killing of multiple lymphoma cell lines in vitro. These 'armed' CIK cells exhibited enhanced intracellular signaling after engaging tumor targets. Cell surface proteome profiling suggested mechanisms by which antibody-armed CIK cells concurrently activated multiple surface proteins, leading to enhanced cytolytic activity. Our surface proteome analysis indicated that CIK cells display enhanced protein signatures indicative of immune responses, cellular activation and leukocyte migration. CONCLUSIONS Here, we characterize the cell surface proteome of CIK cells using a novel methodology that can be rapidly applied to other cell types. Our study also demonstrates that without genetic modification CIK cells can be rapidly armed with monoclonal antibodies, which endows them with high specificity to kill tumor targets.
