Effect of antimicrobial stewardship on antimicrobial prescriptions for selected diseases of dogs in Switzerland.

Background: Antimicrobial stewardship programs (ASPs) are important tools to foster prudent antimicrobial use.

Objective: To evaluate antimicrobial prescriptions by Swiss veterinarians before and after introduction of the online ASP AntibioticScout.ch in December 2016.

Antimicrobial prescriptions in cats in Switzerland before and after the introduction of an online antimicrobial stewardship tool.

Background: Antimicrobial stewardship activities are essential to improve prudent antimicrobial use. The aim of the present study was to evaluate changes in antimicrobial prescriptions in cats after the introduction of prudent use guidelines promoted by an online antimicrobial stewardship tool (AntibioticScout.ch) in Switzerland.

Antimicrobial prescriptions and adherence to prudent use guidelines for selected canine diseases in Switzerland in 2016.

Background: Antimicrobial resistance is an increasing problem in human and veterinary medicine and is closely linked to the use of antimicrobials. The objective of this study was to describe antimicrobial prescriptions for selected canine diseases in Switzerland during 2016.

Methods: Dogs presented to two university hospitals and 14 private practices for acute diarrhoea (AD; n=371), suspected or confirmed urinary tract infections (UTIs; n=245), respiratory tract infections (RTIs; n=274) or wound infections (WIs; n=175) were included.

Prognostic impact of polypharmacy and drug interactions in patients with advanced cancer.

The risk of potential drug-drug interactions (PDI) is poorly studied in oncology. We included 105 patients with advanced non-small-cell lung cancer (NSCLC), 100 patients with advanced breast cancer (BC) and 100 patients of the palliative care unit (PCU) receiving systemic palliative treatment between 2010 and 2015. All patients suffered from advanced incurable cancer and received basic palliative care.

Reconstitution of PTEN activity by CK2 inhibitors and interference with the PI3-K/Akt cascade counteract the antiapoptotic effect of human stromal cells in chronic lymphocytic leukemia.

Evidence suggests that tumor microenvironment is critically involved in supporting survival of chronic lymphocytic leukemia (CLL) cells. However, the molecular mechanisms of this effect and the clinical significance are not fully understood. We applied a microenvironment model to explore the interaction between CLL cells and stromal cells and to elucidate the role of phosphatidylinositol 3 kinase (PI3-K)/Akt/phosphatase and tensin homolog detected on chromosome 10 (PTEN) cascade in this process and its in vivo relevance.

Double impact on p-glycoprotein by statins enhances doxorubicin cytotoxicity in human neuroblastoma cells.

The development of multidrug resistance (MDR) is a major problem during cancer treatment. Drug efflux via ATP-binding cassette (ABC) transporters is the main mechanism responsible for resistance to chemotherapeutics. We have recently observed that statins enhance susceptibility to doxorubicin-induced apoptosis in human rhabdomyosarcoma cells, which is now also observed in human SH-SY5Y neuroblastoma cells.
