Severe acute isolated right ventricular failure has limited dedicated percutaneous temporary mechanical circulatory support options, especially after orthotopic heart transplantation. The advent of the Impella RP device provides a newer option, though an absolute contraindication to device placement is thrombus within the right heart. We present a novel case where catheter-based embolectomy was used to evacuate right heart thrombus before Impella RP placement in a patient with severe acute right ventricular failure due to primary graft dysfunction after orthotopic heart transplantation.
Chimeric antigen receptor (CAR) T-cell therapy is considered as a major scientific breakthrough in cancer immunotherapy. The success of adoptive CAR T-cell therapy for cancer has inspired researchers to expand indications into the area of solid tumors, autoimmune and infectious diseases. The most important factors influencing outcome and durability of the response after infusion of CAR T-cell are proliferation and persistence of this cell subset. It becomes therefore important to detect easily and monitor circulating CAR T-cells into blood samples. Approaches such as quantitative PCR (qPCR) or flow cytometry have been developed. The aim of this study was to set up and optimize a reachable flow cytometry technique using labeled CD19 protein for the measurement of CAR T-cells in infusion bag and patient's blood.
Patients receiving Yescarta in Cell Therapy Unit (Department of hematology, Lille university hospital, France) between April and October 2019 and healthy volunteers were included to set up the flow subset. Moreover, this technique allows monitoring of both authority approved CD19 CAR T-cell.Malignant melanoma is the skin tumor that causes most deaths in Germany. At an early stage, melanoma is well treatable, so early detection is essential. However, the skin cancer screening program in Germany has been criticized because although melanomas have been diagnosed more frequently since introduction of the program, the mortality from malignant melanoma has not decreased. This indicates that the observed increase in melanoma diagnoses be due to overdiagnosis, i.e. to the detection of lesions that would never have created serious health problems for the patients. One of the reasons is the challenging distinction between some benign and malignant lesions. In addition, there may be lesions that are biologically equivocal, and other lesions that are classified as malignant according to current criteria, but that grow so slowly that they would never have posed a threat to patient's life. So far, these "indolent" melanomas cannot be identified reliably due to a lack of biomarkers. Moreover, the likelihood that an in-situ melanoma will progress to an invasive tumor still cannot be determined with any certainty. When benign lesions are diagnosed as melanoma, the consequences are unnecessary psychological and physical stress for the affected patients and incurred therapy costs. Vice versa, underdiagnoses in the sense of overlooked melanomas can adversely affect patients' prognoses and may necessitate more intense therapies. Novel diagnostic options could reduce the number of over- and underdiagnoses and contribute to more objective diagnoses in borderline cases.

However, these applications still await translation into clinical and pathological routine.
To evaluate the risks of overall and site-specific malignancies in Korean patients with primary Sjögren's syndrome (pSS).
Using the Korean nationwide healthcare claims database, we constructed a retrospective cohort for prevalent pSS aged over 50years. After enrollment between January 2012 and December 2014, patients were followed until the development of any malignancy, or until December 2015. Crude incidence rates of malignancies of pSS patients were calculated, and their standardized incidence ratios (SIRs) for malignancies were calculated compared to those in knee osteoarthritis (OA) patients.
A total of 6,359 pSS and 5,476,302 knee OA patients were included in this study. During follow-up (19,474 person-years [PYs]), 310 cases of solid malignancy (158.8/10,000 PYs) and 47 cases of hematologic malignancies (23.5/10,000 PYs) were observed in pSS patients. The risks of overall (SIR 1.30, 95% CI 1.16-1.43), solid (SIR 1.16, 95% CI 1.03-1.29), and hematologic malignancies (SIR 4.80, 95% CI 3.43-6.17) were increased in pSS patients. There was an elevated risk of site-specific malignancy in non-Hodgkin's lymphoma (NHL, SIR 6.45, 95% CI 4.05-8.83), multiple myeloma (SIR 4.88, 95% CI 2.00-7.76), and oropharynx (SIR 4.16, 95% CI 1.90-6.42). The risk of lung cancer was increased only in male pSS patients (2.50, 95% CI 1.02-3.99), while the risk of thyroid cancer was increased in female patients (1.44, 95% CI 1.04, 1.84).
In patients with pSS over age 50, the risk of solid cancers such as oropharynx, thyroid, and lung cancers is also increased in addition to NHL.

The simultaneously increased prevalence of atopic diseases and decreased prevalence of infectious diseases might point to a link between the two entities. Past work mainly focused on either atopic diseases or recurrent infections. We aim to investigate whether risk factors for atopic diseases (ie, asthma, allergic rhinitis, atopic dermatitis, and/or food allergy) differ from risk factors for recurrent respiratory tract infections (RRTIs) in children.
Cross-sectional data were used from 5517 children aged 1 to 18 years who participated in an Electronic Portal for children between 2011 and 2019. Univariable/multivariable logistic regression analyses were performed to determine risk factors for any atopic disease and RRTIs.
Children aged ≥5 years were more likely to have any atopic disease (adjusted odds ratio [OR] 1.50-2.77) and less likely to have RRTIs (OR 0.68-0.84) compared to children aged less than 5 years. Female sex (OR 0.72; 95% confidence interval [CI] 0.63-0.81), low birth weight (OR 0.74; 95% CI 0.
