Perspectives on Drug Development for the Treatment of Chronic Myeloid Leukemia in Pregnant Patients and Patients Who Are Breastfeeding.

Tyrosine kinase inhibitors (TKI) have improved the outcome and life expectancy of patients with chronic myeloid leukemia (CML). Patients are diagnosed with CML at younger ages, and patients treated for CML may become pregnant or choose to breastfeed. The information available to date on the safety of TKIs during pregnancy and lactation and the optimal management of these patients is largely anecdotal, based on personal or small-group experience, and heterogeneous. A panel of interested parties was convened by U.S. Food and Drug Administration to analyze the current data and discuss possible solutions. Possible solutions include prospective data collection, in clinical trials and in routine clinical practice, a more uniform and specific data collection, and greater coordination among involved entities. As patients with cancer are living longer, frequently receiving therapies for extended periods of time (or for life), data on appropriate management of patients through different reproductive phases of life are needed. It is thus time to change our approach for how to study treatment of cancer (including CML) during pregnancy or breastfeeding to develop evidence-based guidelines for safe and effective patient care.

Complete Genome Sequence of Salmonella enterica Serovar Typhimurium Myophage Mutine.

Mutine is a myophage of Salmonella enterica serovar Typhimurium. Here, we present the complete genome of Mutine (161,502 bp) and show that it is similar to that of phage Vi01.

Complete Genome Sequence of Serratia marcescens Podophage Parlo.

Serratia marcescens is an opportunistic human pathogen with multiple resistance mechanisms that infects hospitalized patients. Here, we report the full genome sequence of S. marcescens podophage Parlo. Parlo is most similar to Erwinia phage PEp14 and encodes a 3,764-residue protein assumed to be a homolog of DarB, an antirestriction protein.
