RESUMEN
BACKGROUND: Although reports of reduced nosocomial infections (NI) in very low birth weight infants have been published, the durability of these gains and changes in secondary outcomes, and clinical practices have less often been published. METHODS: This was a retrospective, observational study of NI reduction in very low birth weight infants at two hospital campuses. The intervention began in 2005 with our renewed quality improvement efforts to reduce NI. We compared outcomes before (2000-2005) and after (2006-2009) the intervention by using univariate and multiple regression analyses. RESULTS: We reduced NI by 50% comparing 2000-2005 to 2006-2009 (23.6% vs 11.6%, P < .001). Adjusting for covariates, the odds ratio for NI was 0.33 (confidence interval, 0.26 - 0.42, P < .001) in the more recent era. NI were lower even in infants with birth weight 501-1000 grams (odds ratio = 0.38, confidence interval, 0.29 - 0.51, P < .001). We also reduced bronchopulmonary dysplasia (30.2% vs 25.5%, P = .001), median days to regain birth weight (9 vs 8, P = .04), percutaneously placed central venous catheter use (54.8% vs 43.9%, P = .002), median antibiotic days (8 vs 6, P = .003), median total central line days (16 vs 15, P = .01), and median ventilator days (7 vs 5, P = .01). We sustained improvements for three years. CONCLUSIONS: Quality improvement efforts were associated with sustained reductions in NI, bronchopulmonary dysplasia, antibiotic use, central line use, and ventilator days.

OBJECTIVE: The goal of this work was to study the anticancer activity of cetrorelix, a decapeptide with LHRH receptor antagonist properties in patients with platinum-resistant ovarian cancer. About 80% of primary ovarian cancers and cell lines bear LHRH receptors. Cetrorelix has anticancer activity in in vitro and in vivo ovarian cancer models. METHODS: Eligible patients with ovarian or mullerian carcinoma resistant to platinum chemotherapy received cetrorelix 10 mg subcutaneously every day. Eligibility criteria included age > or = 18, PS < or = 2, measurable disease, chemistries and blood counts in normal range, no estrogen replacement for at least 2 weeks, and no known allergic reactions to extrinsic peptide. In patients volunteering for a biopsy, tissue was taken to perform a LHRH receptor assay. RESULTS: Seventeen patients were treated. Median age was 58 years. Median performance status was 0. Median number of prior chemotherapies was 3. Three patients had partial remissions lasting 9, 16, and 17 weeks. Toxicities effects included grade 4 anaphylactoid reaction (one patient) controlled by cortisol and cimetidine, grade 2 histamine reaction (two patients), grade 2 arthralgia (one patient) 20% cholesterol increase (two patients, who did not require specific treatment), minor hot flushes, headache, and local skin reaction at the injection site. Six of seven samples were LHRH receptor positive for mRNA and/or ligand assay. Two responding patients were LHRH receptor positive. The patient who had no receptor did not respond. CONCLUSION: Cetrorelix has activity against ovarian cancer in this refractory population, and has minimal toxicity, except for potential anaphylactoid reactions. Activity may be mediated through the LHRH receptor.
