Palbociclib in combination with endocrine therapy versus capecitabine in hormonal receptor-positive, human epidermal growth factor 2-negative, aromatase inhibitor-resistant metastatic breast cancer: a phase III randomised controlled trial-PEARL.

Background: Palbociclib plus endocrine therapy (ET) is the standard treatment of hormone receptor-positive and human epidermal growth factor receptor 2-negative, metastatic breast cancer (MBC). However, its efficacy has not been compared with that of chemotherapy in a phase III trial.

Patients And Methods: PEARL is a multicentre, phase III randomised study in which patients with aromatase inhibitor (AI)-resistant MBC were included in two consecutive cohorts.

Reverse Transcription Quantitative Polymerase Chain Reaction for Detection of and Differentiation Between RNA and DNA of HIV-1-Based Lentiviral Vectors.

The purpose of the described method is the detection of and differentiation between RNA and DNA of human immunodeficiency virus (HIV)-derived lentiviral vectors (LV) in cell culture supernatants and swab samples. For the analytical surveillance of genetic engineering, operations methods for the detection of the HIV-1-based LV generations are required. Furthermore, for research issues, it is important to prove the absence of LV particles for downgrading experimental settings in terms of the biosafety level.

The spectrum of Aeromonas-associated diarrhea in tropical Queensland, Australia.

During a twelve-month period (1 July 91-30 June 92), feces from 912 persons from the Townsville region in the dry tropics of Queensland, Australia were evaluated by culture and 45 (4.9%) immunocompetent patients were found to be carrying Aeromonas in their stools. All patients were index cases and no secondary cases from household or close contact of index cases were identified.

Spectrum of extraintestinal disease due to Aeromonas species in tropical Queensland, Australia.

During a 12-month period, the clinical spectrum of extraintestinal disease due to Aeromonas species was determined for 56 patients in tropical Queensland (Australia). Forty-six patients acquired their infection in the community, six patients were infected in the hospital, and four patients were colonized. Demographic risk factors included male gender (67%) and Aboriginal ethnic background (35%).

In vitro susceptibilities of tropical strains of Aeromonas species from Queensland, Australia, to 22 antimicrobial agents.

Greater than 90% of 131 strains of Aeromonas species were susceptible to the aminoglycosides, ureidopenicillins, extended-spectrum cephalosporins, aztreonam, quinolones, tetracycline, and chloramphenicol, and all were uniformly resistant to ampicillin. Except for amoxicillin-clavulanate, sulfonamide, trimethoprim, and trimethoprim-sulfamethoxazole, there was good correlation between the results obtained by the agar dilution and disk diffusion techniques.
