Pathology and systemic therapy of non-clear cell renal cell carcinoma: an overview.

Expert Rev Anticancer Ther 2021 Jul 22. Epub 2021 Jul 22.

Medical Clinic II, J.W. Goethe University, Frankfurt, Germany.

Introduction: Non-clear cell renal cell carcinoma (nccRCC) represents a highly heterogenous group of kidney cancer entities. As most clinical trials predominantly include patients with clear cell RCC (ccRCC), nccRCC treatment guidelines are mainly extrapolated from recommendations in ccRCC. Here, we review and elucidate current data on the pathologic classification and treatment of nccRCC. Read More

Angiotensin receptor-neprilysin inhibitors: Comprehensive review and implications in hypertension treatment.

Hypertens Res 2021 Jul 21. Epub 2021 Jul 21.

The Department of Geriatric and General Medicine, Osaka university Graduate School of Medicine, Suita, Osaka, Japan.

Angiotensin receptor-neprilysin inhibitors (ARNIs) are a new class of cardiovascular agents characterized by their dual action on the major regulators of the cardiovascular system, including the renin-angiotensin system (RAS) and the natriuretic peptide (NP) system. The apparent clinical benefit of one ARNI, sacubitril/valsartan, as shown in clinical trials, has positioned the drug class as a first-line therapy in patients with heart failure, particularly with reduced ejection fraction. Accumulating evidence also suggests that sacubitril/valsartan is superior to conventional RAS blockers in lowering blood pressure in patients with hypertension. Read More

Nitric Oxide System and Bronchial Epithelium: More Than a Barrier.

Front Physiol 2021 30;12:687381. Epub 2021 Jun 30.

Department of Pharmacology, Faculty of Medicine, University of Valencia, Valencia, Spain.

Airway epithelium forms a physical barrier that protects the lung from the entrance of inhaled allergens, irritants, or microorganisms. This epithelial structure is maintained by tight junctions, adherens junctions and desmosomes that prevent the diffusion of soluble mediators or proteins between apical and basolateral cell surfaces. This apical junctional complex also participates in several signaling pathways involved in gene expression, cell proliferation and cell differentiation. Read More

Effects of venoms on neutrophil respiratory burst: a major inflammatory function.

J Venom Anim Toxins Incl Trop Dis 2021 28;27:e20200179. Epub 2021 Jun 28.

Université de Paris, INSERM-U1149, CNRS-ERL8252, Centre de Recherche sur l'Inflammation (CRI), Laboratoire d'Excellence Inflamex, Faculté de Médecine Xavier Bichat, Paris, France.

Neutrophils play a pivotal role in innate immunity and in the inflammatory response. Neutrophils are very motile cells that are rapidly recruited to the inflammatory site as the body first line of defense. Their bactericidal activity is due to the release into the phagocytic vacuole, called phagosome, of several toxic molecules directed against microbes. Read More

One year in review 2021: novelties in the treatment of rheumatoid arthritis.

Clin Exp Rheumatol 2021 Jul-Aug;39(4):705-720. Epub 2021 Jul 5.

Rheumatology Unit, Department of Medical Sciences, University of Ferrara and Azienda Ospedaliero-Universitaria S. Anna, Cona, Ferrara, and Epidemiology Unit, Italian Society for Rheumatology, Milan, Italy.

Management of rheumatoid arthritis (RA) has evolved over the years as a result of better understanding of the role of different therapeutic strategies, as well as following an increasing availability of new disease-modifying antirheumatic drugs. However, the role of patients in sharing decisions, as well as the rules informing precision medicine or the principles to follow in case of specific comorbidities or extra-articular manifestations are still areas for improvement. Moreover, in 2020, the novel Coronavirus disease-19 outbreak has completely changed many attitudes in terms of assessment and treatment paradigms in most clinical diseases, including RA. Read More

Paediatr Drugs 2021 Jul 7;23(4):373-380. Epub 2021 Jul 7.

Divisions of Pediatric Infectious Diseases and Clinical Pharmacology, Department of Pediatrics, Children's Mercy Hospital and the University of Missouri-Kansas City, 2401 Gillham Road, Kansas City, MO, 64108, USA.

The antibiotic combination of vancomycin (VAN) and piperacillin-tazobactam (PTZ) has been associated with an increased risk of acute kidney injury (AKI) in both adult and pediatric patients. In this review, we highlight some of the limitations of existing pediatric studies evaluating the combination of VAN/PTZ, focusing on AKI risk in specific pediatric patient populations. We also review the variability in defining AKI in children and provide guidance to clinicians for use of prospective surveillance and stewardship in mitigating the risk of AKI in pediatric patients treated with combination of VAN/PTZ.

Insights Into the Results of Sotagliflozin Cardiovascular Outcome Trials: Is Dual Inhibition the Cherry on the Cake of Cardiorenal Protection?

Drugs 2021 Jul 7. Epub 2021 Jul 7.

Division of Endocrinology and Metabolism and Diabetes Center, First Department of Internal Medicine, Medical School, Aristotle University of Thessaloniki, AHEPA University Hospital, 1 St. Kiriakidi Street, 54636, Thessaloniki, Greece.

Sotagliflozin is a dual sodium-glucose co-transporter (SGLT) 2 inhibitor, manifesting a 20-fold higher inhibitory activity for SGLT2 than for SGLT1. Differences in SGLT2 over SGLT1 selectivity of the available agents have been proposed to relate to variability in efficacy and safety characteristics. In contrast to other SGLT2 inhibitors, the cardiorenal effects of sotagliflozin in type 2 diabetes had not been explored until recently, when the results of SOLOIST-WHF (focusing on heart failure [HF] outcomes) and SCORED (focusing on renal outcomes) were published.

Emerging therapies for AML with myelodysplasia-related changes: slowly but surely moving the needle.

Expert Opin Emerg Drugs 2021 Jul 6:1-13. Epub 2021 Jul 6.

University of North Carolina School of Medicine, Chapel Hill, NC, USA.

: Patients with acute myeloid leukemia with myelodysplasia-related changes (AML-MRC) have historically poor outcomes with conventional chemotherapy regimens. Current treatment strategies focus on intensive induction therapy followed by allogeneic stem cell transplant or a less intensive approach with hypomethylating agents with or without venetoclax. CPX-351 is a liposomal formulation of cytarabine and daunorubicin that has been shown to significantly improve response rates and survival compared with 7 + 3 (continuous infusion cytarabine plus anthracyclines).
