Abstract
Abstract
Background: Eribulin mesylate, a novel non-taxane microtubule dynamics inhibitor, has been approved for patients with metastatic breast cancer (MBC) who have previously received at least two chemotherapeutic regimens for MBC. This study evaluates efficacy and safety of eribulin + trastuzumab (TRAZ) as first-line therapy for human epidermal growth factor receptor 2 positive (HER2+) locally recurrent or MBC.
Methods: Patients received eribulin mesylate at 1.4 mg/m2 IV on days 1, 8 and TRAZ initial dose of 8 mg/kg IV on day 1 every 21 days, followed by 6 mg/kg on day 1 of each subsequent cycle. For study inclusion, patients could have been previously treated with TRAZ, but at least 12 months should have passed since any prior neoadjuvant or adjuvant chemotherapy was used. Endpoints include objective response rate (ORR) (primary), safety, progression free survival (PFS), time to response (TTR), and duration of response (DOR). Tumor assessments are evaluated every 6 weeks for the first 6 cycles and every 6–12 weeks thereafter per RECIST 1.1.
Results: Updated results presented here as of June 1, 2012; 37 of 52 planned patients have been treated. Patient characteristics are as follows: median age: 58 years (range, 31–81), 70% have luminal subtype, 95% are stage IV disease, and 73% have visceral disease, 46% had prior neo/adjuvant, 22% had prior anthracycline and 32% had prior taxane, 35% had original diagnosis of MBC. Patients received median of 7 (1,20) cycles for eribulin and 9 (1,23) cycles for TRAZ. The most common treatment related AEs are reported in Table 1.
Treatment-related serious AEs were reported for 4 (11%) patients; neutropenia 3 (8%) and febrile neutropenia 2 (6%) patients each. Eight patients have discontinued treatment due to disease progression (PD). Best patient responses are found in Table 2.
Conclusions: Based on the updated preliminary results of this Phase II study, the combination of eribulin + trastuzumab as first-line therapy for HER2+ locally recurrent or MBC appears to demonstrate an acceptable safety profile with considerable tumor responses, including in patients with ER/PR+ disease. Accrual is ongoing and study completion is anticipated prior to SABCS 2012.

Abstract
Legionella pneumophila is a waterborne pathogen that has been isolated sporadically from drinking water distribution systems (DWDS). Resistance to disinfectants is mainly attributed to the association of cells with amoebae, but biofilms are also thought to provide some degree of protection. In the present work, a two-stage chemostat was used to form heterotrophic biofilms from drinking water to study the influence of chlorine on the presence of naturally occurring L. pneumophila. The pathogen was tracked in planktonic and sessile biofilm phases using standard culture recovery techniques for cultivable cells and a peptide nucleic acid fluorescence in situ hybridisation assay for total cells. The results showed that the total number of L. pneumophila cells in biofilms was not affected by the concentrations of chlorine tested, and the presence of L. pneumophila could not be detected by culturing. To restrict the outbreaks of disease caused by this bacterium, efforts need to be concentrated on preventing L. pneumophila from re-entering an infectious state by maintaining residual disinfectant levels through the entire DWDS network so that the resuscitation of cells via contact with amoebae is prevented.

Abstract
Blastocystis hominis (B. hominis) is a protozoan that may inhabit the human gastrointestinal tract. In our study we reviewed the signs and symptoms of patients at Wilford Hall with stool specimens positive for B. hominis. These patients fell into four groups, HIV-positive adults, foreign nationals, children, and adults not known to be HIV positive. B. hominis caused an acute self-limited diarrheal illness, or chronic gastroenteritis with nausea, abdominal pain, and mild diarrhea. Metronidazole effectively relieved the symptoms and cleared the organism in some but not all patients.
